Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of plastic processing waste recycling equipment, and more specifically, to a flash recycling device for plastic processing. Background Technology
[0002] Currently, the initial raw material for plastic bottle processing is the preform, which is generally cylindrical and inverted on a support mold head. After being heated, it enters the blown film mold of the blown film machine. The inside of the blown film mold is the molded shape of the finished plastic bottle to be processed. By drawing a vacuum, the preform clamped between the blown film molds is blown to obtain the formed plastic bottle product quickly.
[0003] In actual production, due to gaps and incomplete closure of blown film molds, flash is prone to occur at the bottle neck of plastic bottles. The flash needs to be removed by a subsequent cutting device, which generates flash waste. Since the flash at the bottle neck of plastic bottles is arc-shaped and relatively thin, the cutting direction of the flash waste is unstable during the cutting process, and it is easy to stick to the ground. In the existing technology, the above-mentioned waste falls directly to the ground, causing pollution in the factory area, and it is difficult to clean up later. Utility Model Content
[0004] The purpose of this invention is to provide a flash recycling device for plastic processing. This flash recycling device is mainly used for recycling flash waste from the bottle necks of plastic bottles, which can prevent the waste from falling onto the factory ground, facilitate subsequent unified recycling and processing, and improve the hygiene of the factory production and processing environment.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] A flash recycling device for plastic processing includes a frame with a control box on one side. A conveyor belt passes between the frames, and plastic bottles are placed on the conveyor belt at intervals via clamps. An electrically controlled cylinder is embedded in the top plate on the other side of the frame. The lower end of the electrically controlled cylinder has a telescopic piston rod connected downward to several limit frames, which are clamped onto the flipped plastic bottles. An L-shaped support plate is provided on the front side of the other side of the frame, and a baffle is provided on the inner side of the L-shaped support plate. A mechanical arm is limited and rotated above the baffle. Rotary bearing seats are embedded in both sides of the baffle via connecting pieces. The rotating part of the rotating bearing seat is rotatably connected to a flash recycling trough. A rotating motor is connected to the outer side of the rotating part of one of the rotating bearing seats. A waste collection box with an opening at the top is provided below the flash recycling trough.
[0007] As a further optimization of this solution, both ends of the upper surface of the L-shaped support plate are fixed with push cylinders. The piston rods of the push cylinders are connected inward to one side of the push plate. A knife holder is fixedly installed on the other side of the push plate. A cutter is clamped on the knife holder. The cutter, driven by the push cylinder, is aligned inward to cut the burr of the plastic bottle mouth area and pushes into the knife groove on the outer side of the baffle. Limiting guide rods are installed on the upper surface of the L-shaped support plate on both sides of the push cylinder through the base. A sliding seat is fitted on the rod of the limiting guide rod. The lower part of the sliding seat is fixed to the upper surface of the push plate.
[0008] As a further optimization of this solution, both sides of the flash recycling trough protrude upwards. In the horizontal state, the upper front surface of the flash recycling trough does not contact the cutter. In the vertical state, the lower front surface of the flash recycling trough overlaps the surface of the inclined downward material plate. The inclined downward material plate is fixed at the upper edge of the inner side of the waste collection box.
[0009] As a further optimization of this solution, an L-shaped support plate is provided on the lower surface of the frame, and a limiting frame is fixed on the surface of the L-shaped support plate. Sliding grooves are provided on both sides of the limiting frame, and the protruding positioning block on the bottom surface of the waste collection box is slidably embedded in the sliding groove.
[0010] As a further optimization of this solution, the waste collection box is provided with a push-pull handle on its outer side.
[0011] As a further optimization of this solution, the control box is connected to the control end of the rotating clamping robot arm, the control end of the conveyor belt, the rotating motor, the pushing cylinder and the electric control cylinder respectively through wiring, and the control box is connected to an external power supply.
[0012] As a further optimization of this solution, the width of the inclined downward material plate is greater than the width of the flash recovery trough.
[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows:
[0014] This invention utilizes a rotating clamping robotic arm structure to invert and clamp multiple plastic bottles from a conveyor belt above a flash recycling trough. A baffle limits the movement, and a cylinder drives a cutter to cut the flash around the bottle neck, inserting it into a groove on the outer side of the baffle. The cut flash falls into the flash recycling trough below. A control box controls a rotating motor to rotate the trough from a horizontal to a vertical position, dumping the flash waste along a sloping downward feed plate into a waste collection box for unified recycling. The waste collection box is positioned using a limiting frame on an L-shaped tray, ensuring the flash waste falls smoothly into the box and preventing it from falling onto the factory floor. This facilitates subsequent unified recycling and improves the hygiene of the factory's production and processing environment. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.
[0022] To address the problem that the existing technology for removing plastic bottle neck burrs is problematic because the burrs are rounded and thin, resulting in unstable cutting paths and easy adhesion to the ground, causing the burrs to fall directly to the ground, polluting the factory area and making them difficult to remove later;
[0023] like Figure 1 As shown, this application includes a frame 1, a control box 2 is provided on one side of the frame 1, a conveyor belt 6 passes through the frame 1, and plastic bottles 7 are placed on the conveyor belt 6 at intervals by card seats. An electric control cylinder 3 is embedded in the top plate on the other side of the frame 1. The lower end of the electric control cylinder 3 has a telescopic piston rod 4 connected downward to several limit frames 5. The limit frames 5 are clamped onto the body of the plastic bottle 7 after it is flipped over. An L-shaped bracket plate 8 is provided on the front side of the other side of the frame 1.
[0024] like Figure 2As shown, the inner side of the L-shaped support plate 8 is provided with a baffle 18, and the mechanical arm 17 is limited to rotate and grip above the baffle 18.
[0025] like Figure 5 As shown, rotating bearing seats 26 are embedded in both sides of the baffle 18 via connecting pieces 22. The rotating part of the rotating bearing seat 26 is rotatably connected to the burr recycling trough 19. A rotating motor 21 is connected to the outer side of the rotating part of the rotating bearing seat 26 on one side. A waste collection box 10 with an opening at the top is provided below the burr recycling trough 19.
[0026] like Figure 2 As shown, both ends of the upper surface of the L-shaped support plate 8 are fixed with push cylinders 11. The piston rods of the push cylinders 11 are connected inward to one side of the push plate 13. The other side of the push plate 13 is fixedly installed with a knife holder 15. A cutter 16 is clamped on the knife holder 15. The cutter 16 is aligned and cuts the burr of the bottle mouth area of the plastic bottle 7 inward under the drive of the push cylinders 11 and pushes into the knife groove on the outer side of the baffle 18. The upper surface of the L-shaped support plate 8 on both sides of the push cylinders 11 is equipped with a limiting guide rod 12 through the base. A sliding seat 14 is fitted on the rod of the limiting guide rod 12. The sliding seat 14 is fixed to the upper surface of the push plate 13 below.
[0027] like Figure 3 As shown, both sides of the flash recycling trough 19 protrude upwards. In the horizontal state, the upper surface of the front end of the flash recycling trough 19 does not contact the cutter 16. In the vertical state, the lower surface of the front end of the flash recycling trough 19 overlaps the surface of the inclined downward material plate 20. The inclined downward material plate 20 is fixed at the upper edge of the inner side of the waste collection box 10.
[0028] like Figure 4 As shown, an L-shaped tray 9 is provided on the lower surface of the frame 1. A limiting frame 25 is fixed on the surface of the L-shaped tray 9. Slide grooves are provided on both sides of the limiting frame 25. The raised positioning block 23 on the bottom surface of the waste collection box 10 is slidably embedded in the slide groove. A push-pull handle 24 is provided on the outer side of the waste collection box 10.
[0029] Specifically, control box 2 is connected via wiring to the control end of the rotating clamping robotic arm 17, the control end of the conveyor belt 6, the rotating motor 21, the push cylinder 11, and the electric control cylinder 3. Control box 2 is powered externally. To prevent material leakage, the width of the inclined downward material plate 20 is greater than the width of the flash recovery trough 19. During operation, control box 2 pauses the movement of the conveyor belt 6 and controls the rotating clamping robotic arm 17 to clamp several plastic bottles from above the conveyor belt 6, flipping them to a position above the outer baffle 18. Then, control box 2 controls the electric control cylinder 3 to move the limit clamping frame 5 downwards, clamping it onto the flipped plastic bottle 7 to improve cutting stability. Then, control box 2 continues to control the push cylinder 11, causing the push plate 13 to move along the limit guide rod 12, pushing the cutter 16 inwards to align and cut the flash in the bottle mouth area of the plastic bottle 7. The flash scrap recovery trough 19 is initially horizontal, collected by the cutting flash scrap. Then, the control box 2 rotates the motor 21 to rotate the flash scrap recovery trough 19 downwards to a vertical position. At this point, the lower front surface of the flash scrap recovery trough 19 overlaps the surface of the inclined downward material plate 20, pouring the flash scrap into the waste collection box 10 for unified recycling. The waste collection box 10 is positioned by the limiting frame 25 on the surface of the L-shaped support plate 9. The limiting frame 25 slides and embeds into the protruding positioning block 23 on the bottom surface of the waste collection box 10, ensuring the flash scrap falls smoothly into the waste collection box 10, preventing it from falling onto the factory floor, facilitating subsequent unified recycling and improving the hygiene of the factory's production and processing environment.
