Description

Technical Field

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

[0002] In traditional plastic product processing, the core function of the feeding device is to accurately deliver plastic parts to the feed inlet of the molding equipment. In the early stages and in some small and medium-sized processing enterprises, the common practice was to use a robotic arm to grasp and feed the parts individually. This involved programming and controlling the movement trajectory of the robotic arm to grasp one plastic part at a time from the plastic parts stacking area or hopper, move it to the designated position on the conveyor table, and then the robotic arm would reset and repeat the grasping action, thus completing the feeding process in a cycle.

[0003] The core problems of the traditional single-grip feeding mode of robotic arms are concentrated in efficiency and cost. In terms of efficiency, intermittent single operations require waiting for the robotic arm to reset, which cannot achieve continuous feeding. Especially when processing small plastic parts, the accumulated time loss will directly limit the production capacity of the back-end equipment. In terms of cost, the purchase and installation costs of precision robotic arms are high, and the long-term cost pressures such as replacement of worn parts of the robotic arm, system debugging and maintenance, and energy consumption are significant. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for processing plastic products, comprising an operating table and a conveyor table installed on the operating table. A double-chain transmission device is installed on the operating table, and multiple bearing plates are fixed between the two sets of chains of the double-chain transmission device. A limited displacement conveying component is installed on the operating table, and a pushing component located at the tail end of the double-chain transmission device and coaxial with the conveyor table is also installed. The limited displacement conveying component includes a push cylinder installed on the operating table. The piston rod of the push cylinder is fixed with a movable frame extending to the tail end of the double-chain transmission device. A baffle is fixed on the side of the movable frame, and a support plate located at the tail end of the double-chain transmission device and connected to the bearing plate is fixed at the bottom. The bottom of the support plate near the bearing plate has a slope. The support plate can be located on the same axis as the pushing component and the conveyor table.

[0005] Furthermore, the pushing component includes a side plate, on which a pushing cylinder is mounted, and a pushing block is fixed to the piston rod of the pushing cylinder.

[0006] Furthermore, two sets of auxiliary rollers that are connected to the conveyor table are fixed on the operating platform.

[0007] Furthermore, a fixed frame is also installed on the operating table, and the movable frame is located inside the fixed frame. Both the fixed frame and the movable frame are equipped with a downward-pressing cylinder and multiple sets of guide rods. The piston rod of the downward-pressing cylinder is fixed with a downward pressure plate connected to the corresponding guide rod.

[0008] Furthermore, the operating platform is fixed with stop bars located on both sides of the double chain drive device.

[0009] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0010] The feeding device for processing plastic products, through the combination of a double chain drive and a multi-bearing plate structure, and the cooperation of the pushing component and auxiliary rollers, can smoothly push a row of plastic parts on the support plate to the conveyor table.

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-3This embodiment of a feeding device for processing plastic products includes an operating table 1. A conveyor table 17 is fixedly installed on the top left side of the operating table 1. The conveyor table 17 is used to transport plastic parts to the subsequent processing area. A double chain drive device 2 is fixed on the top of the operating table 1, located on the right side of the conveyor table 17. The double chain drive device 2 is driven by a stepper motor. Between the two sets of parallel chains of the double chain drive device 2, multiple bearing plates 16 are evenly spaced along the length of the chains to synchronously carry multiple rows of plastic parts to achieve intermittent movement. A limited displacement conveying component is installed on the top of the operating table 1 at the tail end of the double chain drive device 2 and close to the conveyor table 17. This component is used to accurately transfer the plastic parts on the bearing plates 16 to the pushing station. The top of the operating table 1, located at the tail end of the double chain drive device 2 and on the same axis as the conveyor table 17, is used to push the plastic parts on the support plate 15 to the pushing component on the conveyor table 17.

[0017] The top of the operating platform 1 is also fixed with two sets of stop bars 3. The two sets of stop bars 3 are located on both sides of the double chain drive device 2 and are parallel to the direction of chain movement, in order to prevent the plastic parts on the bearing plate 16 from tipping over or shifting during the conveying process.

[0018] Additionally, the limited displacement conveying assembly includes a push cylinder 9 fixed on the operating table 1 and opposite to the double chain drive device 2. The piston rod end of the push cylinder 9 is fixed to a movable frame 10. The movable frame 10 can move towards and away from the conveyor table 17 under the drive of the push cylinder 9. A baffle 14 is fixed on the side of the movable frame 10 near the double chain drive device 2. The baffle 14 is used to block and limit the conveyed row of plastic parts. A support plate 15 is fixed at the bottom of the movable frame 10. The top of the support plate 15 is flush with the top of the support plate 16, and the side of the support plate 15 near the support plate 16 has a slope to facilitate the smooth transition of the plastic parts on the support plate 16 to the surface of the support plate 15. The movement of the movable frame is driven by the operation of the push cylinder, which can drive the support plate to separate from the support plate and align it with the conveyor table. The double chain drive device will only run again when the support plate is close to the support plate, and will stop when it is separated.

[0019] Meanwhile, a fixed frame 8 is fixed on the top of the operating table 1, and a movable frame 10 is slidably set inside the fixed frame 8. A downward-pressing cylinder 11 is vertically installed on the top of both the fixed frame 8 and the movable frame 10, and two guide rods 12 are passed through both the fixed frame 8 and the movable frame 10. A downward-pressing plate 13 is fixed to the end of the piston rod of the downward-pressing cylinder 11. The downward-pressing plate 13 is fixedly connected to the lower end of the guide rod 12. The guide rod 12 can slide along the guide holes of the fixed frame 8 and the movable frame 10. First, when the plastic parts are moved to the support plate, the downward-pressing cylinder 11 on the movable frame is driven, and the downward-pressing plate 13 can be pressed down vertically to temporarily fix the plastic parts on the support plate 15. Then, the push cylinder retracts, and the support plate drives the plastic parts to align with the conveyor table. When the next row of plastic parts is moved to the tail end of the double chain drive device, the downward-pressing cylinder on the fixed frame pushes down to drive the downward-pressing plate, which can also press down and tighten the plastic parts on the bearing plate to achieve pre-waiting.

[0020] In addition, the pushing component includes a side plate 5 fixed on the operating table 1 and distributed opposite to the conveyor table. A pushing cylinder 6 is installed on the side plate 5. A pushing block 7 is fixed to the piston rod of the pushing cylinder 6. The pushing block 7 is made of soft rubber. By operating the pushing cylinder, the plastic part can be pushed into the conveyor table. The pushing block can prevent scratches on the surface of the plastic part during pushing.

[0021] To further explain, two sets of auxiliary rollers 4 are also fixed on the top of the operating table 1. The two sets of auxiliary rollers 4 are used to improve the smoothness of the push cylinder lifting the support plate to the conveyor table. When the plastic part is pushed onto the auxiliary rollers, the rotation of the auxiliary rollers is used to help the plastic part smoothly transition from the push station to the conveyor table 17, reducing frictional resistance.

[0022] The working principle of the above embodiments is as follows:

[0023] First, rows of plastic parts are placed on the support plate. A double-chain drive system moves the support plate, thus conveying the plastic parts until the first row is moved onto the support plate and contacts the baffle. At this point, the lower cylinder on the movable frame drives the lower pressure plate to press the plastic parts on the support plate firmly. A push cylinder then drives the movable frame to retract, moving the support plate away from the support plate and aligning it with the conveyor table. The double-chain drive system then stops intermittently. The lower cylinder on the fixed frame then drives the corresponding lower pressure plate to press the next row of plastic parts on the support plate firmly. A push cylinder then drives the push block, pushing the next row of plastic parts towards the conveyor table. During this process, auxiliary rollers assist in improving the smoothness of the transfer to the conveyor table. The push cylinder, lower cylinder, and push cylinder then reset. The double-chain drive system moves the support plate, and the process is repeated to complete the conveying of the next group. This achieves continuous processing, reduces processing and conveying costs, and facilitates maintenance.
