Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic cap production technology, specifically to a plastic cap coating and feeding device. Background Technology
[0002] In the modern industrial packaging field, plastic caps are widely used in many industries such as beverages, chemicals, and pharmaceuticals due to their good plasticity, corrosion resistance, and cost advantages. As an important means of surface decoration for plastic caps, decals can not only add a unique visual effect to the product, but also effectively convey brand information and enhance the product's brand image and market competitiveness.
[0003] However, the feeding process for plastic cap decals mainly relies on traditional manual or semi-automatic methods. Manual feeding requires workers to place the plastic caps one by one at the gluing and decal station. This process is not only labor-intensive but also slow. During the peak season for beverages, a medium-sized beverage factory needs to produce hundreds of thousands of paper cups and matching plastic caps every day. If manual feeding is used, a large amount of manpower and time costs are required, and the production efficiency is far from meeting market demand. Even with semi-automatic feeding, frequent manual intervention is still required. The automation level of the equipment is limited, making it difficult to achieve high-speed and continuous production, which makes it difficult to effectively improve the overall production efficiency. With the continuous rise in labor costs, the traditional feeding method that relies on a large amount of manual operation has brought a heavy cost burden to enterprises. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] Please see Figure 1-4 This embodiment of a plastic cap coating and feeding device includes an operating table 1, on which a rotating table 2 is mounted. Multiple adsorption stations 3 are mounted on the rotating table 2. These adsorption stations are used to adsorb and position the plastic caps. The rotation of the rotating table allows the plastic caps to be adjusted in position. On the left side of the rotating table 2, on the operating table 1, a dispensing component 4, a feeding component 5, and a sensing support 6 are mounted. The dispensing component 4 receives the plastic caps transferred from an external transfer device and performs dispensing on the top surface of the plastic caps. Then, the feeding component moves the dispensed plastic caps to the top of the rotating table. The sensing sensor on the sensing support 6 detects that the feeding component 5 is holding the plastic cap and sends a signal to the control system. The control system drives the rotating table 2 to rotate. Using positioning sensors built into the rotating table, such as photoelectric switches and encoders, one of the adsorption stations 3 is precisely positioned directly below the feeding component, ensuring accurate placement of the plastic caps.
[0020] like Figure 2-3 As shown, the dispensing assembly 4 includes a dispensing frame 41 fixed on the operating table 1, a support plate 46 fixed in the middle of the dispensing frame 41, and a glue tank 42 containing glue fixed on the top of the dispensing frame 41. A push cylinder 43 is installed on the top of the glue tank 42, and a piston rod 44 extending to the inside of the glue tank 42 is fixed to the push cylinder 43. A dispensing head 45 is fixed at the bottom of the glue tank 42. By operating the push cylinder, the piston rod can be moved, thereby accurately squeezing the glue in the glue tank through the dispensing head to complete the automatic dispensing operation.
[0021] The support plate 46 has two sets of protruding plates on its left side. A frame box 47 is fixed between the tops of the protruding plates. The frame box 47 is concave and has a strip hole at the top. Two guide posts 48 are fixed inside the frame box 47. A slider 49 passes between the guide posts 48. A base plate 491 is fixed to the bottom of the slider. A translation cylinder 413 is installed on the back of the base plate 491. The ejector rod of the translation cylinder 413 is fixed to the bottom of the support plate 46. Therefore, by ejecting and retracting the ejector rod of the ejector cylinder, the slider can be driven to move back and forth through the guide posts. Thus, it can accept plastic caps transferred from external transfer devices. The plastic caps are then transferred to the area below the dispensing head to complete the dispensing operation. The plastic caps with the dispensing completed are then transferred to the loading area to wait.
[0022] In addition, such as Figure 3 As shown, an upper-lifting cylinder 410 is installed on the front of the base plate 491, and uprights 411 distributed on both sides of the upper-lifting cylinder 410 are inserted through it. The ejector rod of the upper-lifting cylinder 410 is fixed with a support block 412 fixed to the top of the uprights 411. The support block 412 can pass through the slider 49 and the elongated hole. The support block is adapted to the shape of the inner side of the plastic cover. When the upper-lifting cylinder 410 is working, the ejector rod pushes the support block 412 to move up and down along the uprights 411, so that the upper-lifting cylinder drives the support block to lift up, thereby extending to the inner side of the plastic cover. When the translation cylinder moves the slider to the position, it extends to the inner side of the plastic cover through the support block and drives the plastic cover to move until it is below the dispensing head. Then, it is lifted up by the upper-lifting cylinder, so that the plastic cover can be lifted to a certain range. The plastic cover is then sent to a suitable position near the dispensing head to complete the dispensing operation. After the dispensing is completed, it retracts and moves back to the feeding area. Then, the plastic cover is lifted to a suitable height again to wait for the feeding component to pick up the material.
[0023] like Figure 4The feeding assembly 5 includes a mounting plate 51 fixed on the operating table 1. A plate base 52 is fixed to the top of the mounting plate 51, and four sliding columns 55 pass through and penetrate the operating table 1. An ejector plate 54 is fixed between the tops of the sliding columns 55. An ejector cylinder 53 is installed on the top of the plate base 52. The ejector rod of the ejector cylinder 53 is fixed to the bottom of the ejector plate 54. A rotary cylinder 56 is installed on the top of the ejector plate 54. A rotary plate 57 is fixed to the rotating end of the rotary cylinder 56. The rotation angle of the rotary cylinder 56 is designed to be 90° to ensure that the clamping cylinder 58 can accurately switch between two positions: the feeding area of the dispensing assembly and the suction station above the rotating table. After rotating to the correct position, it coordinates with the lifting action of the ejector cylinder 53. To achieve precise transfer of the plastic cap from material picking to placement, a clamping cylinder 58 is installed on the side of the rotating plate 57 away from the bottom of the rotating cylinder 56. A slot is opened on the opposite side of the clamping end of the clamping cylinder 58. The slot can be adapted to the shape of the edge of the plastic cap to improve the stability of clamping. When picking up the material, the ejector cylinder 53 drives the ejector plate 54 to descend, so that the clamping cylinder 58 is close to the plastic cap in the feeding area of the dispensing assembly. After the clamping cylinder 58 closes and clamps, the ejector cylinder 53 rises and resets. After the rotating cylinder 56 drives the plastic cap to rotate above the adsorption station, the ejector cylinder 53 descends again to place the plastic cap in the adsorption station 3. The clamping cylinder 58 is released, and the ejector cylinder 53 rises and resets, completing the transfer.
[0024] The working principle of the above embodiments is as follows:
[0025] During equipment operation, the external transfer device moves the plastic cap to be processed to the working area of the dispensing assembly. At this time, the translation cylinder in the dispensing assembly actuates, driving the slider to move along the guide column, moving the base plate and related components to the receiving position to receive the plastic cap delivered by the external transfer device. Subsequently, the upper lifting cylinder operates, pushing the support block to rise along the column. The support block extends to the inside of the plastic cap, and the translation cylinder drives the slider to move, using the support block to move the plastic cap to below the dispensing head. Then, the upper lifting cylinder operates again, lifting it close to the dispensing head. The head is positioned appropriately to prepare for dispensing. The push cylinder drives the piston rod to move within the glue tank, precisely extruding glue through the dispensing head to dispense it onto the top surface of the plastic cap. After dispensing, the upper push cylinder lowers the support block to its original position, and the translation cylinder moves again to transfer the dispensed plastic cap to the loading area. Then, the upper push cylinder raises the support block again, lifting the plastic cap to a suitable height, awaiting the loading assembly's removal. The ejector cylinder drives the ejector plate to descend, causing the rotary cylinder, rotary plate, and clamping cylinder to move downwards, bringing the clamping cylinder closer to the dispensing point. In the plastic cap feeding area of the adhesive assembly, the clamping cylinder closes, and its clamping end groove matches the edge of the plastic cap, stably clamping the plastic cap. Then, the ejector cylinder rises and resets, causing the plastic cap to rise. The rotary cylinder moves, causing the rotary plate and plastic cap to rotate, so that the plastic cap is accurately moved above the adsorption station of the rotary table. When the sensor on the induction support detects that the clamping cylinder of the feeding assembly is ready to release the material, it sends a signal to the control system. The control system drives the rotary table to rotate. Through the built-in photoelectric switch, encoder and other positioning sensors, one of the adsorption stations is accurately stopped directly below the feeding assembly. Then, the ejector cylinder descends again, placing the plastic cap on the adsorption station. The adsorption station activates the adsorption function to fix the plastic cap. The clamping cylinder releases, the ejector cylinder rises and resets, completing the transfer of the plastic cap. The rotary table continues to rotate, taking the plastic cap from the adsorption station to the next process. At the same time, the next adsorption station moves to below the feeding assembly, waiting to receive a new plastic cap after dispensing. This cycle repeats, realizing continuous automated processing of plastic caps.
