Description

A tray forming mechanism for a tray making and inserting machine

Technical Field

The invention relates to the technical field of packaging machinery, and in particular to a tray forming mechanism for a tray making and inserting integrated machine.

Background Art

The tray making and loading machine is a type of packaging machinery, which is used to produce trays and load the product packaging bottles into the trays.

In the process of producing the bracket, a bracket forming mechanism is needed to process the film raw material into the bracket. The existing bracket forming mechanism is generally composed of two parts, an upper mold and a lower mold. The upper mold and the lower mold are brought together to squeeze the film raw material into the mold cavity to form the bracket;

When the film raw material is extruded into the mold cavity, the film raw material will be pulled to move into the mold cavity to cover the mold cavity. However, as the extrusion amplitude increases, the distance between the upper mold and the lower mold gradually decreases. Since the process of processing the bracket using the film raw material is continuous (multiple brackets need to be processed on a whole film raw material), there will be an area of the film raw material on the outside of the mold, so that the upper mold and the lower mold are close to each other and contact the film raw material, pressing it (at this time the film raw material has not completely covered the cavity and needs to continue to be extruded), so that the movement of the film raw material is restricted, resulting in the film raw material being difficult to extend into the mold cavity. It is easy for the film raw material to fail to completely cover the mold cavity, resulting in the processed bracket being thin or having holes, etc., affecting the quality of the bracket. For this reason, we propose a bracket forming mechanism for a bracket making and inserting machine.

Summary of the invention

The object of the present invention is to provide a bracket forming mechanism for a bracket making and inserting machine, so as to solve the problem proposed in the above background technology that as the extrusion amplitude increases, the distance between the upper mold and the lower mold gradually decreases, which restricts the movement of the film raw material, making it difficult for the film raw material to extend into the mold cavity, and easily resulting in the film raw material not completely covering the mold cavity, the processed bracket being thin or having holes.

To achieve the above-mentioned object, the present invention provides the following technical solutions: a bracket forming mechanism for a bracket making and inserting machine, comprising: a support, a guide column is provided on the support, an upper die seat is provided above the guide column, an upper die is provided on the upper die seat, a lower die seat is slidably provided on the guide column and is located between the upper die and the support, a lower die is provided on the side of the lower die seat facing the upper die, and the bracket forming mechanism further comprises: a driving member provided on the support to drive the lower die seat to slide along the length direction of the guide column to make the lower die approach or move away from the upper die;

Among them, the upper mold includes a mold body, a raised part and a telescopic mechanism installed on the mold body, and an edge part installed on the movable end of the telescopic mechanism. The edge part is sleeved on the outside of the raised part. When the telescopic mechanism works, it drives the edge part to move closer to or away from the lower mold.

Preferably, a slot is provided in the cavity of the lower die, a contact sensor is provided in the slot, and a PLC controller is connected to the contact sensor to control the telescopic mechanism to be powered on and drive the edge component to move closer to the lower die;

There are several groups of contact sensors, several groups of contact sensors are evenly distributed in the cavity of the lower mold, and several groups of contact sensors are connected in series with the PLC controller.

Preferably, a mounting groove is provided on the side of the edge component facing the lower mold, and a moving part that moves along the transmission direction of the film raw material is slidably inserted into the mounting groove. An elastic part is provided on the moving part to support the moving part. Conductive parts that fit each other are provided on the moving part and the mounting groove. The conductive parts are connected to a PLC controller. When the moving part moves, the two groups of conductive parts are misaligned, so that the PLC controller controls the telescopic mechanism to work and drives the edge component to move away from the lower mold.

Preferably, telescopic parts are provided on both sides of the upper mold and the lower mold, and pressing parts are provided on the movable ends of the telescopic parts. The telescopic parts on the upper and lower sides work to bring the pressing parts on the upper and lower sides closer to fix the transmitted film raw material.

Preferably, a stripper plate is slidably provided on the lower mold to push out the bracket manufactured in the lower mold cavity, and an elastic element is provided on the stripper plate to provide thrust to the stripper plate, so as to facilitate the removal of the manufactured bracket from the lower mold cavity.

Preferably, cooling channels are provided inside the lower mold and the upper mold, and openings connected to the cooling channels are provided on the lower mold and the upper mold to introduce or export cooling medium into or out of the cooling channel, so that the cooling medium flows inside the cooling channel to cool the lower mold and the upper mold.

Compared with the prior art, the beneficial effects of the present invention are as follows: the upper mold in the device is composed of a mold body, a telescopic mechanism, an edge component and a protruding component, so that in the process of the upper mold and the lower mold being combined to extrude the film raw material to produce the bracket, the edge component of the upper mold does not contact the lower mold first, so that the edge of the upper mold will not contact the film raw material, thereby reducing the restriction on the film raw material in the process of moving to the lower model cavity, ensuring that the film raw material can fully enter the cavity of the lower mold, thereby ensuring the quality of the bracket production.

A lower die base 3 is slidably provided on the guide column 2, and the lower die base 3 is located below the upper die 7. A lower die 4 is provided on the side of the lower die base 3 facing the upper die 7. A driving member 5 is provided on the support 1, and a moving end of the driving member 5 is connected to the lower die base 3, and is used to move the lower die base 3 and the lower die 4 up and down;

Furthermore, a stripping plate 9 is slidably provided above the lower mold 4, and the stripping plate 9 can move up and down at the lower mold 4 (a connecting piece is installed on the stripping plate 9, and the connecting piece is slidably installed on the lower mold 4, and the stripping plate 9 can move up and down at the lower mold 4 through the connecting piece), and an elastic element is provided between the stripping plate 9 and the lower mold 4; in the process of the lower mold 4 and the upper mold 7 moving away from each other, the extrusion force of the upper mold 7 on the stripping plate 9 disappears, and the stripping plate 9 is pushed upward by the elastic element reset expansion, which will push the bracket in the cavity of the lower mold 4 outward (the stripping plate 9 pushes the film raw material, because the manufactured bracket is still on the film raw material), which is convenient for mold stripping;

Furthermore, cooling channels are provided inside the lower mold 4 and the upper mold 7, and openings 8 connected to the cooling channels are provided on the lower mold 4 and the upper mold 7. The cooling medium is injected into the cooling channels through the openings 8. After the cooling medium flows in the cooling channels, it is discharged from another opening 8. The cooling medium flows inside the cooling channels, which cools the lower mold 4 and the upper mold 7.

Please refer to FIG. 2 , FIG. 3 , FIG. 4 and FIG. 5 , the upper mold 7 includes a mold body 71 , a protruding component 74 , a telescopic mechanism 72 and an edge component 73 ;

The protruding part 74 is mounted on the mold body 71, and the protruding part 74 matches the cavity of the lower mold 4. The telescopic mechanism 72 is mounted on the mold body 71, and the edge part 73 is mounted on the moving end of the telescopic mechanism 72, and the edge part 73 is in a U-shape, and the protruding part 74 is located on the inner side of the edge part 73. When the telescopic mechanism 72 works, it drives the edge part 73 to move up and down, so that it is close to or away from the lower mold 4;

Furthermore, a slot 13 is provided in the cavity of the lower mold 4, and a contact sensor 12 (the contact sensor 12 is also a pressure sensor, model MS5561C) is provided in the slot 13, and a PLC controller (model TPC24-24TD) is connected to the contact sensor 12; when the film material is extruded into the cavity of the lower mold 4, the film material will touch the contact sensor 12, and after receiving the information, the PLC controller controls the telescopic mechanism 72 to be powered on, driving the edge component 73 to move closer to the lower mold 4, so that the upper mold 7 and the lower mold 4 are closed, the film material is extruded, and the bracket is made and formed; the edge component 73 works more intelligently;

There are several groups of contact sensors 12, which are evenly distributed in the cavity of the lower mold 4, and are connected in series with the PLC controller; the PLC controller controls the telescopic mechanism 72 to work only after the several groups of contact sensors 12 are touched, ensuring that the film material has fully entered the cavity, avoiding the edge component 73 from contacting the lower mold 4 too quickly and restricting the film material, avoiding affecting the extension of the film material into the cavity of the lower mold 4, and ensuring the quality of the bracket processing;

In summary, the process of making the support is as follows: when the film raw material is transmitted to between the upper mold 7 and the lower mold 4, the driving member 5 is energized to work, and the lower mold seat 3 is pushed upward, so that the lower mold 4 and the upper mold 7 are brought closer together; during the process of approaching, the raised part 74 on the upper mold 7 will move into the cavity of the lower mold 4, squeeze the film raw material, and move the film raw material into the cavity of the lower mold 4 until the film raw material completely covers the cavity of the lower mold 4; then the telescopic mechanism 72 is energized to work, so that the edge part 73 is brought closer to the lower mold 4, and the film raw material between the upper mold 7 and the lower mold 4 is squeezed to complete the forming of the support; then the driving member 5 works again to move the lower mold seat 3 in the opposite direction, so that the lower mold 4 is separated from the upper mold 7, and the formed support is removed from the cavity of the lower mold 4; then the film raw material continues to be transmitted, the area with the support on the film raw material is removed, and the blank area on the film raw material is moved between the upper mold 7 and the lower mold 4, and processed again;

When the protruding part 74 squeezes the film material, the edge part 73 is moved upward by the telescopic mechanism 72 to prevent the edge part 73 from contacting and squeezing the film material, thereby ensuring that the film material enters the cavity of the lower mold 4 normally.

Embodiment 2:

As a preferred solution, please refer to Figures 3 and 4. A mounting groove 75 is provided on the side of the edge component 73 facing the lower mold 4. A moving member 76 is slidably inserted in the mounting groove 75. The sliding direction of the moving member 76 is the same as the transmission direction of the film raw material. An elastic member is provided between the moving member 76 and the mounting groove 75 for supporting the moving member 76; conductive members are provided on both the moving member 76 and the mounting groove 75, and the two groups of conductive members are fitted with each other, and the conductive members are connected to the PLC controller; after the edge component 73 moves closer to the lower mold 4 and squeezes the film raw material, if the film raw material continues to move in the cavity of the lower mold 4, the film raw material will be pulled, causing the film raw material to move, moving with the moving member 76, and causing the two groups of conductive members to be misaligned; after receiving the information, the PLC controller controls the telescopic mechanism 72 to work, so that the edge component 73 moves away from the lower mold 4, so that the film raw material moves into the cavity of the lower mold 4 without restriction; after a period of time, the PLC controller controls the telescopic mechanism 72 to reset the edge component 73 to continue squeezing the film raw material.

Embodiment 3:

As a preferred solution, please refer to Figures 2, 4 and 5. Telescopic parts 10 are provided on both sides of the upper mold 7 and the lower mold 4, and pressing parts 11 are provided on the movable ends of the telescopic parts 10; when the telescopic parts 10 work, the upper and lower groups of pressing parts 11 move closer together to fix the transported film raw materials; in the process of extruding the film raw material to make the bracket, the film raw material can be fixed on the side facing the next processing area, so that in the process of extruding the film raw material, the film raw material in the next processing area will not be pulled, thereby avoiding the misalignment of the bracket in the next processing area (multiple brackets will be processed on the film raw material, and the bracket made by the mold will be transmitted to the next processing area for use and processing together with the film raw material).
