Description

Aluminum can color printing drying equipment

Technical Field

The invention relates to the technical field of drying, in particular to color printing drying equipment for aluminum cans.

Background technique

After aluminum cans are printed, the printing ink needs to be cured and dried through a drying process to ensure the quality and durability of the printing effect.

The existing drying of cans usually utilizes a heat source to solidify and dry the color-printed cans first, and then utilizes hot air to reinforce and dry the solidified cans and accelerate the evaporation of volatile components in the ink. This can relatively shorten the production cycle and increase production capacity. However, when the existing drying equipment dries the cans according to the aforementioned steps, a conveyor belt is usually used to transport the cans so that the cans pass through the drying rod solidification drying area and the hot air reinforcement drying area in sequence. The cans are conveyed in the drying rod solidification drying area in an intermittent state. When they enter the hot air reinforcement drying area in the same conveying state and conveying speed, they are easily affected by the weight of the cans themselves, the wind force of the hot air and the conveying speed, and the cans are prone to tipping over, thereby reducing the reliability of the hot air drying process. In addition, the hot air drying in this conveying state and conveying speed requires a long drying distance, which will cause a waste of space and resources.

Detailed ways

In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

Please refer to Figures 1 and 2. A color-printed drying equipment for aluminum cans includes a drying rod curing drying channel 1 and a hot air reinforcement drying channel 2 which are arranged in sequence from left to right. The drying rod curing drying channel 1 is equipped with a conveyor belt 1 4, and the hot air reinforcement drying channel 2 is equipped with a conveyor belt 2 5. The conveying speed of the conveyor belt 2 5 is less than that of the conveyor belt 1 4. A stable transition mechanism 6 is provided between the drying rod curing drying channel 1 and the hot air reinforcement drying channel 2. During the drying process, the conveyor belt 1 4 conveys the color-printed cans from left to right, so that they pass through the drying rod curing drying channel 1 for curing and drying. After drying, the color-printed surface of the cans has been cured and has a certain stability. Then, the stable transition mechanism 6 stably transfers the color-printed surface-cured cans from the conveyor belt 1 4 to the conveyor belt 2 The cans are placed on the conveyor belt 1 5 and then transported by the conveyor belt 2 5 to pass through the hot air reinforcement drying channel 2 for hot air reinforcement drying, which accelerates the evaporation of volatile components in the ink and reinforces the curing strength of the color printing surface, further strengthens the stability of the color printing surface, and improves the durability of the color printing. In the process of transfer, the stable transition mechanism 6 allows the cans to move smoothly and steadily from the conveyor belt 1 4 to the conveyor belt 2 5, and on the other hand, it allows the cans to be stably transformed from the original single-row spacing distribution conveying state to the double-row gathered conveying state. By changing the conveying speed and conveying state of the cans, the hot air reinforcement drying distance is effectively shortened, and the stability of the hot air reinforcement drying process is improved, thereby improving the reliability of the hot air reinforcement drying process and effectively avoiding the occurrence of cans tipping over during the drying process.

Referring to Figures 1, 2, 3, 4 and 5, the stable transition mechanism 6 includes a control component 61, a stable transfer roller 62 that is symmetrically arranged front and back and rotates synchronously in the opposite direction and is arranged at the intersection of conveyor belt 1 4 and conveyor belt 2 5, and a guide diffusion component 63 that cooperates with the stable transfer roller 62 to guide the conveying members transferred to conveyor belt 2 5. The guide diffusion component 63 includes a rotating member 631 that rotates intermittently and reciprocatingly and a guide port 632 that is fixedly arranged on the rotating member 631. As shown in Figure 3, the guide port 632 is symmetrically distributed by guide plates. The control component 61 synchronously controls the stable transfer roller 62 to rotate synchronously in the opposite direction and the rotating member 631 to rotate intermittently and reciprocately. The rotation speed of the stable transfer roller 62 is less than the conveying speed of conveyor belt 1 4, and at the same time, is greater than the conveying speed of conveyor belt 2 5. As shown in Figure 2, during the drying process, conveyor belt 1 4 transports the cans from left to right to the stable transfer roller 62, and the stable transfer The rollers 62 rotate synchronously in the opposite direction to clamp and transfer the cans. During the transfer process, not only the stability of the can conveying state is improved, but also the speed of the cans is reduced, so that they are smoothly transferred from the fast conveying state to the slow conveying state. After the cans are smoothly transferred to the conveyor belt 25, they enter the guide area of the guide port 632 as the conveyor belt 25 is conveyed. After a short period of guidance by the guide port 632, the cans are regularly changed into a double-row gathering state on the conveyor belt 25. As shown in Figure 3, after the cans are transferred by the stable transfer roller 62, the intermittently reciprocating rotating member 631 changes the guiding state of the guide port 632 intermittently and reciprocatingly, so that the cans are changed from the original single-row conveying state to the double-row conveying state. Among them, the transfer contact surface of the stable transfer roller 62 is a rubber surface, which on the one hand further improves the stability of the transfer process, and on the other hand effectively avoids the damage to the color printing surface of the cans during the transfer process.

3 and 4 , the guide opening 632 is distributed up and down to form two upper and lower guide areas, which guide and convey the conveying member from a position close to the upper end of the conveying member and a position close to the lower end of the conveying member respectively. As shown in FIG4 , the stability of the can conveying process can be effectively improved by limiting the guidance of the upper and lower guide areas on the cans, wherein the two ports of the guide opening 632 are both trumpet-shaped, as shown in FIG3 . The trumpet-shaped ports not only facilitate the cans to enter the guide area smoothly, but also facilitate the cans to be smoothly moved out of the guide area, which is further beneficial to improving the stability and reliability of the conveying process.

Referring to Figures 1, 2, 4 and 5, the control component 61 includes a gear box 612 with a built-in gear component 611. The gear box 612 is provided with an input shaft 613 and three output shafts 614, one of the output shafts 614 intermittently reciprocates and is fixedly connected to the rotating member 631. It is intended that the output shaft 614 is an intermittent rotation control shaft, and the other two output shafts 614 rotate synchronously in the opposite direction and are coaxially connected to the symmetrical stable transfer rollers 62, respectively. It is intended that the two output shafts 614 are synchronous rotation control shafts. As shown in Figure 5, the gear assembly 611 includes a gear 1 6111, a gear 2 6112, a gear 3 6113 and a gear 4 6114. The gear 1 6111 is coaxially connected to the three output shafts 614, respectively, and the gear 2 6112 is symmetrically distributed and is respectively connected to the gears on the synchronous rotation control shaft. The gears 1 and 2 are meshed with each other, and the gears 1 and 2 are meshed with each other respectively. The gears 1 and 2 are coaxially connected with the gears 1 and 2 and meshed with each other at the same time. The gears 1 and 2 are coaxially connected with each other at the same time and meshed with the gears 1 and 2 on the intermittent rotation control shaft at the same time. The gears 1 and 2 are coaxially connected with each other at the same time and meshed with the gears 1 and 2 on the intermittent rotation control shaft at the same time. The gears 1 and 2 are coaxially connected with each other at the same time and meshed with the gears 1 and 2 on the intermittent rotation control shaft at the same time. The gears 1 and 2 are coaxially connected with each other at the same time and meshed with the gears 1 and 2 on the intermittent rotation control shaft at the same time. The gears 1 and 2 are coaxially connected with each other at the same time and meshed with the gears 1 and 2 on the intermittent rotation control shaft at the same time. The input shaft 613 is coaxially connected with one of the gears 1 and 2 6112.

Referring to Figures 1, 2 and 3, a heating cavity 3 is provided on the drying rod curing and drying channel 1, and the heating cavity 3 is connected with the hot air reinforcement drying channel 2. The heat energy generated by the drying rod curing and drying channel 1 is used to heat the heating cavity 3. The air is heated by the heating cavity 3 to form hot air that enters the hot air reinforcement drying channel 2 to heat the cans, thereby accelerating the evaporation of volatile components in the ink and reinforcing the curing strength of the color printing surface. There is no need to set up a separate heating source, which effectively improves the utilization rate of resources and reduces the waste of resources.

Referring to Figures 1 and 2, a sealed transition cavity 7 is set between the drying rod curing drying channel 1 and the hot air reinforcement drying channel 2, and the intersection of conveyor belt 1 4 and conveyor belt 2 5 is located in the transition cavity 7. The transition cavity 7 seals and connects the drying rod curing drying channel 1 and the hot air reinforcement drying channel 2 together and forms a transition zone in the middle, which reduces the loss of heat energy and keeps the cans in a drying environment at all times. The transition zone has a certain distance interval. Combined with the setting that the port of the drying rod curing drying channel 1 close to the hot air reinforcement drying channel 2 only allows the conveying parts and conveyor belt 1 4 to pass through, the situation in which the air convection in the drying rod curing drying channel 1 and the hot air reinforcement drying channel 2 generates hot air in the drying rod curing drying channel 1 and affects its drying and curing effect can be effectively reduced.

Referring to Figures 1, 2 and 6, the output port of the heating chamber 3 connected to the hot air reinforcement drying channel 2 is spaced apart from the guide port 632. As shown in Figure 2, the setting of the output port increases the transition distance of the transition zone on the one hand, further avoiding the convection of air in the drying rod curing drying channel 1 and the hot air reinforcement drying channel 2 affecting the drying and curing effect of the drying rod curing drying channel 1, and the hot air generated by the output port acts on the cans after the cans are in a double-row aggregation state, further improving the stability and reliability of the hot air reinforcement drying process, wherein a plurality of groups of inclined guide plates 8 are arranged along the conveying direction in the hot air reinforcement drying channel 2, and the inclined guide plates 8 in the plurality of groups are distributed in an inverted U shape, as shown in Figure 2, in the process of hot air flowing from left to right, the inclined guide plates 8 are used to increase the activity of the hot air flow, and the hot air is guided in the direction of the cans, so that the hot air can fully act on the cans, thereby improving the efficiency of hot air drying.
