Description

Lifting supporting device and cover film heat sealing equipment

Technical Field

The utility model relates to the technical field of automatic production line filling equipment, in particular to a lifting supporting device for heat sealing of a product cover film and cover film heat sealing equipment.

Background

The automatic capsule filling line is designed for filling contents such as capsule coffee, capsule beverage, capsule tea and the like. When the top cover film heat-sealing welding is carried out on the capsules in the production process, the general procedure is that the cover film is automatically placed on a capsule cup on a conveyor belt of a production line, and then a heating piece is pressed down on the capsule cup for heat sealing. When the heating element is pressed down, the bottom of the capsule cup on the production line needs to be provided with a supporting force to ensure that the heating element has an acting point; meanwhile, the supporting force needs to be automatically withdrawn after the heat sealing is finished, so that the capsule is transported away without obstruction after the heat sealing. The conveyor belt is generally suspended in the middle and erected at two ends of the production line for normal operation, and drives the conveyor belt to rotate and transport repeatedly through driving turntables at two ends of the production line. When the heating piece is pressed down, the conveying belt has no supporting force and the supporting device is needed to provide supporting force. The existing production line generally directly controls the lifting of the supporting device through aerodynamic force, and has the defects that the lifting is strong, the capsule cup at the station to be heat-sealed is easy to vibrate, and the content in the cup is easy to spill; in addition, the direct pneumatic lifting supporting device has no locking and positioning function, and when the heating piece is pressed down, the supporting device is easy to be compressed, so that the supporting force is insufficient, and poor welding is caused.

The heat insulating sheet 73 serves to insulate the heat of the heating block 71 from being conducted to the guide lower plate 62.

The specific production operation process of the cover film heat sealing equipment provided by the utility model is as follows:

When the conveyor belt 42 conveys the machined piece with the cover film placed in the die 41 to a station where the cover film heat sealing equipment is located, the air cylinder 40 on the lifting supporting device 1 is started, the body 46 of the air cylinder 40 moves to a state that the pneumatic shaft 47 stretches out and is opened under the aerodynamic force, and the body 46 of the air cylinder 40 drives the guide connecting plate 32 connected with the body 46 to move leftwards together with the guide sliding plate 30, so that the guide ring 31 on the guide sliding plate 30 moves synchronously. At this time, due to the high-low guiding action between the first positioning portion 311 and the second positioning portion 312 in the guide ring 31, the bearing moves up from the first positioning portion 311 to the second positioning portion 312, the bearing will drive the lifting plate 20 connected thereto to rise together, the lifting plate 20 is gradually lifted from the rest position to the positioning pin 441 at the bottom of the mold 41 to fall into the positioning hole 23 on the lifting plate 20, thereby playing a role in positioning and supporting the mold 41. In the process of gradually lifting the lifting plate 20, the guide column 21 on the lifting plate 20 synchronously passes through and lifts in the guide column sleeve 11 on the bottom plate 10, and due to the limiting effect of the guide column sleeve 11, the guide column 21 can only pass through and lift upwards without inclination and dislocation, so that the lifting plate 20 fixedly connected with the guide column 21 is limited to lift vertically upwards. Meanwhile, due to the continuous aerodynamic force input, the body 46 of the air cylinder 40 is positioned at the position where the pneumatic shaft 47 extends out and is opened, and the bearing is fixed in the second positioning portion 312 of the guide ring 31, so that continuous support of the lifting plate 20, that is, continuous support of the mold 41 is realized, and the performance of the film covering heat sealing operation is ensured.

After the lifting supporting device 1 supports the die 41, opening the cover film heat sealing device 2; the driving shaft 51 of the driving member 50 drives the elastic member 60 and the heating member 70 to integrally move downward until the heat seal head 72 contacts the cover film placed on the work piece. At this time, the driving shaft 51 drives the guide upper plate 61 to move downward, the guide upper plate 61 is compressed along the guide rod 64 toward the lower plate 62, and the compression force is transmitted to the heat seal head 72, so that the cover film is sufficiently pressed against the edge of the workpiece to be sufficiently welded. Meanwhile, the guide upper plate 61 does not collide with the guide lower plate 62 due to the reaction force of compression of the spring 63.

After the heat seal welding is finished, the driving shaft 51 drives the guide upper plate 61 to move upwards, and when the guide upper plate 61 rises to the screw cap at the top end of the guide rod 64, the guide upper plate 61 cannot deviate from the guide rod 64 due to the limiting effect of the screw cap, so that the guide upper plate 61 rises synchronously with the guide lower plate 62 connected with the guide post rod 64; the heating element 70 is connected to the lower guide plate 62 and thus rises synchronously, so that after the welding is completed, the heat-sealing head 72 rises to be separated from the cover film. The driving shaft 51 drives the elastic member 60 and the heating member 70 to integrally rise to the original positions and then stop, and the heat sealing welding of the cover film of the workpiece is completed.

After the heating member 70 is lifted off the cover film on the workpiece, the direction of the driving force of the air cylinder 40 in the lifting support device 1 is reversed, the body 46 of the air cylinder 40 is pulled back and moved to one side of the baffle 14 connected with the air shaft 47 under the action of the reverse pneumatic force, and the air shaft 47 completely penetrates into the body 46 of the air cylinder 40. At the same time, the body 46 of the cylinder 40 drives the guide connection plate 32 connected with the cylinder and the guide slide plate 30 to move rightwards together, and the guide ring 31 on the guide slide plate 30 moves synchronously with the guide connection plate. At this time, due to the high-low guiding effect between the first positioning portion 311 and the second positioning portion 312 in the guide ring 31, the bearing moves down from the second positioning portion 312 to the first positioning portion 311, the bearing drives the lifting plate 20 connected with the bearing to descend together, the lifting plate 20 is gradually pulled down from the original supporting position, and the positioning hole 23 on the lifting plate 20 is separated from the positioning pin 441 at the bottom of the mold 41, so that the mold 41 is separated from the support, and is sent to the next station by the conveyor belt 42. In the process of gradually descending the lifting plate 20, the guide column 21 on the lifting plate 20 synchronously passes through and descends in the guide column sleeve 11 on the bottom plate 10, and due to the limiting effect of the guide column sleeve 11, the guide column 21 can only pass downwards without inclined dislocation, so that the lifting plate 20 fixedly connected with the positioning column is limited to move vertically downwards. Meanwhile, when the body 46 of the air cylinder 40 is positioned at the position where the pneumatic shaft 47 completely penetrates the air cylinder 40, due to the gravity action of the lifting plate 20, the bearing can be fixed in the first positioning part 311 of the guide ring 31 without continuous reverse aerodynamic force input, so that the lifting plate 20 is pulled down, the die 41 is separated from the support of the lifting support device 1, and the workpiece after the film covering and heat sealing can be guaranteed to be conveyed to the next station by the conveying belt 42.
