A conveying device for processing plastic products

Abstract

This utility model relates to the field of plastic product processing technology, specifically a conveying device for plastic product processing. It includes a double-belt conveyor system and multiple positioning and labeling components mounted on the double-belt conveyor system. It also includes a left single-belt conveyor system connected to the tail end of the double-belt conveyor system, a middle single-belt conveyor system connected to the tail end of the left single-belt conveyor system, and a right single-belt conveyor system connected to the tail end of the middle single-belt conveyor system. This conveying device for plastic product processing, through the layout of the double-belt main conveyor system and the three sets of single-belt conveyors, allows for independent collection of workpieces in each unloading area. When a turnover box in a certain unloading area is full, the pushing component can transfer the workpiece to the single-belt conveyor corresponding to another empty box, without interrupting the main conveyor line.

Description

Technical Field

[0001] This utility model relates to the field of plastic product processing technology, specifically to a conveying device for processing plastic products. Background Technology

[0002] In the telecommunications equipment manufacturing industry chain, plastic casings are core components, and their processing involves multiple stages such as injection molding, surface treatment, and labeling. The conveying device is a crucial piece of equipment connecting these processes, especially during the labeling stage. Ensuring the stability and continuity of casing transport is essential for accurate label application and ensuring product quality. Currently, the industry primarily uses a traditional model for conveying plastic casings for telecommunications equipment: a single linear conveyor line coupled with pallet support. The conveyor line runs along a fixed straight path, and the pallet receives the injection-molded plastic casings from the upstream process and smoothly transports them to the labeling area. After labeling is completed, the casings are then transported to the final unloading point for centralized collection.

[0003] While this traditional conveying mode can meet basic conveying needs, it exposes significant efficiency bottlenecks in actual production. The core problem is the saturation shutdown phenomenon in the material unloading stage. Since the production of plastic shells for communication equipment is mostly a batch continuous operation, once the collection containers at the unloading point, such as turnover boxes, are full of products, the entire conveyor line must be stopped. Only after the operators transfer the full containers and replace them with empty containers can the conveyor line be restarted to continue receiving subsequent products. During this process, not only is the upstream labeling process forced to be interrupted, but the injection-molded shells also cannot be conveyed in time, resulting in flow interruption or accumulation problems between processes. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a conveying device for processing plastic products, comprising a double-belt conveyor and multiple sets of positioning components and labeling components installed on the double-belt conveyor; further comprising a left single-belt conveyor connected to the tail end of the double-belt conveyor, a middle single-belt conveyor connected to the tail end of the left single-belt conveyor, and a right single-belt conveyor connected to the tail end of the middle single-belt conveyor; a pushing component is installed on each of the double-belt conveyor, the left single-belt conveyor, and the middle single-belt conveyor; the pushing component includes a side plate, a push cylinder is installed on the side plate, an L-shaped plate is fixed to the piston rod of the push cylinder, a pushing cylinder is installed on the back of the L-shaped plate, and a push plate is fixed to the piston rod of the pushing cylinder.

[0005] Furthermore, the L-shaped plate is provided with guide posts that are fixed to the push plate.

[0006] Furthermore, the two ends of the push plate extend in opposite directions to form baffles.

[0007] Furthermore, the positioning assembly includes a convex plate and a transverse plate. A limiting cylinder is installed at the bottom of the transverse plate, and a stop post is fixed to the piston rod of the limiting cylinder. An upper lifting cylinder is installed on the side of the convex plate, and an upper lifting plate is fixed to the piston rod of the upper lifting cylinder.

[0008] Furthermore, the labeling assembly includes a column, a side plate fixed on the column, a concave plate fixed on the surface of the side plate, a sliding plate, and a drive motor mounted on the back. The shaft end of the drive motor is located in the groove of the concave plate. A U-shaped groove is formed on the concave plate. A ring plate is fixed to the shaft end of the drive motor. A T-shaped block is fixed on the ring plate. A guide wheel that slides in the ring plate and the U-shaped groove is rotatably connected to the back of the T-shaped block. An adsorption device is installed at the bottom of the sliding plate.

[0009] Furthermore, two sets of buffers are installed on the surface of the concave plate, and two sets of rubber heads are installed on the T-block.

[0010] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0011] The conveying device for processing plastic products uses a layout of a main conveyor line with dual belt conveyors and three sets of single belt conveyors. Each unloading area can collect workpieces independently. When a turnover box in a certain unloading area is full, the pushing component can transfer the workpiece to the single belt conveyor corresponding to other empty boxes without stopping the main conveyor line. This completely solves the problem of traditional conveyor lines stopping completely when one stops, and ensures the continuous operation of injection molding and labeling processes.

[0017] 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.

[0018] Please see Figure 1-4 This embodiment describes a conveying device for processing plastic products, including a conveying structure, a positioning component 6, a labeling component 5, and a pushing component 7. The conveying system adopts a layout of main conveying and multi-branch conveying. The conveying structure includes a double-belt conveyor 1, a left single-belt conveyor 2, a middle single-belt conveyor 3, and a right single-belt conveyor 4. The double-belt conveyor 1 serves as the main conveying line, used to carry workpieces to complete the positioning and labeling processes. Its tail end is connected to the head end of the left single-belt conveyor 2. The left single-belt conveyor 2, the middle single-belt conveyor 3, and the right single-belt conveyor 4 serve as branch unloading lines, arranged in a sequential unloading structure. The tail end of the left single-belt conveyor 2 is connected to the head end of the middle single-belt conveyor 3, and the tail end of the middle single-belt conveyor 3 is connected to the head end of the right single-belt conveyor 4. Each of the four conveyors has an independent unloading area at its end, where turnover boxes can be placed to collect workpieces, realizing multi-path parallel unloading.

[0019] like Figure 2The number of positioning components 6 is no less than four sets, with the first and third sets serving as pre-waiting units, and the second and third sets lifting the tray so that the tray at the tail end can dock with the left single belt conveyor 2. This is used to fix the workpiece position before labeling and ensure labeling accuracy. The positioning component 6 includes a convex plate 61 and a horizontal plate 65 fixed inside the frame of the double belt conveyor 1. A limiting cylinder 66 is installed vertically at the bottom of the horizontal plate 65. The piston rod of the limiting cylinder 66 is fixed with a stop post 67. When the workpiece is conveyed to the positioning area, the piston rod of the limiting cylinder 66 extends, and the stop post 67 rises to block the workpiece from moving forward, thereby achieving axial positioning of the workpiece. An upper lifting cylinder 62 is installed on the right side of the convex plate 61. The piston rod of the upper lifting cylinder 62 is fixedly connected to the upper top plate 63. After the stop post 67 blocks the workpiece, the piston rod of the upper lifting cylinder 62 extends, pushing the bottom of the tray on the upper top plate 63 to lift the tray and separate it from the belt, preventing deviation during labeling.

[0020] like Figure 3 The labeling component 5 is installed beside the double belt conveyor 1, close to and above the second set of positioning components 6, for automated labeling of workpieces. The labeling component 5 includes a column 51 fixed to the frame of the double belt conveyor 1, a side plate 52 fixed to the side of the column 51, a drive motor 54 installed on the back of the side plate 52, the output shaft of the drive motor 54 passing through the side plate 52 and fixedly connected to a ring plate 55, and a concave plate 53 fixed to the front of the side plate 52, the front of the concave plate 53 having an opening. The side plate 52 has a U-shaped groove, and a sliding plate 56 is slidably connected to the front. An adsorption device 57 is installed at the bottom of the sliding plate 56. A T-shaped block 58 is fixed at the top front of the sliding plate 56. A guide wheel that slides in the ring plate 55 and the U-shaped groove is installed on the back of the T-shaped block 58. When the drive motor 54 drives the ring plate 55 to rotate, the guide wheel slides along the U-shaped groove, driving the T-shaped block 58 to perform reciprocating linear motion. When the T-shaped block 58 drives the sliding plate 56 to reciprocate, the adsorption device 57 accurately sticks the label to the surface of the positioned workpiece.

[0021] Among them, a pair of buffers 510 are installed on the concave plate 53, and a rubber head 59 that can cooperate with the corresponding buffer 510 is fixed on the T-block 58. The buffer can be achieved when the T-block 58 moves to the end of the stroke to avoid rigid impact and ensure the smooth labeling process.

[0022] like Figure 4The pushing components 7 are respectively installed on the tail side of the double belt conveyor 1, the tail side of the left single belt conveyor 2, and the tail side of the middle single belt conveyor 3, and are used to transfer the workpiece from the current conveyor line to the next conveyor line to realize multi-path material feeding. The pushing components 7 include side plates 71 fixed on the outer side of the tail end of the double belt conveyor 1, the left single belt conveyor, and the middle single belt conveyor. A piston cylinder 72 with the piston rod facing upward is installed on the plate surface of the side plate 71. The piston rod of the piston cylinder 72 is fixed with an L-shaped plate 73, and the piston rod pushes the piston upward. The cylinder pushes the L-shaped plate to adjust the lifting and lowering of the L-shaped plate. A push cylinder 74 is installed on the back of the L-shaped plate 73, and a guide post 76 is inserted through it. The piston rod of the push cylinder 74 is fixed with a push plate 75 connected to the guide post 76. The left and right ends of the push plate 75 extend in opposite directions to form baffles. The guide post improves the stability of the push plate movement. The push cylinder and the push cylinder can drive the push plate to lift and push. The specific shape of the push plate can play a blocking role, so that the pallet can be moved to the designated position and pushed into the corresponding conveying device.

[0023] The working principle of the above embodiments is as follows:

[0024] After injection molding, the workpiece is placed onto the belts of a dual-belt conveyor system by hand or robotic arm. The dual-belt conveyor system moves the workpiece along the main conveyor path and into the working area of ​​the positioning components. As the main conveyor line, the dual-belt structure ensures the stability of the workpiece during transport, preventing workpiece deviation caused by uneven force on one side of the belt. This provides a foundation for subsequent positioning and labeling processes. When the workpiece moves to the second set of positioning components, the piston rod of the limiting cylinder of this component extends, driving the stop column to rise into the conveyor path to block the workpiece's advance. Simultaneously, the piston rod of the upper lifting cylinder extends, pushing the upper plate upward to lift the bottom of the pallet, completely separating the pallet from the belts of the dual-belt conveyor system. This prevents pallet deviation caused by belt vibration and ensures the workpiece remains horizontal and stable during labeling. If a workpiece at the second set of positioning components is currently undergoing labeling operations, it will be blocked by the first set of positioning components when it arrives, achieving a pre-waiting function and avoiding process congestion. After the workpiece is labeled, it can... The first branch is completed by directly conveying the material from the double belt conveyor. When the first branch is full, the L-shaped plate is moved down by the push cylinder in the first set of pushing components, so that the push plate is in contact with the belt of the double belt conveyor, thus blocking the conveyed pallet. At the same time, the third set of positioning components will block the push plate of the subsequent conveyor, which serves as a waiting function. Then, the fourth set of positioning components lifts up to the bottom of the pallet and supports it. Then, the push cylinder drives the push plate to push out, thus pushing the steering plate to the left single belt conveyor. The second branch is completed by the left single belt conveyor. When the second branch is full, the pallet is pushed to the middle single belt conveyor by the push component on the left single belt conveyor to complete the third branch. Then, the pallet is pushed to the right single belt conveyor by the push component on the middle single belt conveyor to complete the fourth branch. When the turnover box of any branch conveyor is full, the operator only needs to transfer the full box and replace it with an empty box to maintain continuous operation without stopping the machine, so as to realize the continuous processing and conveying of batch workpieces.
