Description

Technical Field

[0001] This utility model relates to the field of hollow plastic sheet processing technology, specifically a device for cleaning the inner hole of a hollow plastic sheet. Background Technology

[0002] Hollow plastic sheets, such as PP hollow sheets and PC hollow sheets, are widely used in advertising backdrops, stationery materials, industrial packaging, and product shock absorption due to their lightweight, high strength, environmental friendliness, and recyclability. However, the production and use of hollow plastic sheets often involve die-cutting and drilling operations, which leave waste such as plastic scraps and cutting residues in the inner holes of the hollow sheets. Therefore, it is necessary to clean the inner holes.

[0003] Normally, workers use air guns to blow through plastic waste. However, this method often results in a lot of plastic waste being missed, leading to poor blowing results.

[0004] Chinese patent discloses a plastic hollow board cleaning device (authorization announcement number CN214767459U). The patented technology has multiple air blowing heads evenly spaced in the air blowing component, which can simultaneously blow plastic waste in the hollow compartments of multiple plastic hollow boards, resulting in high blowing efficiency. The lifting component includes a lifting plate and a lifting column, with the lifting column used to control the lifting plate to rise or fall, and can blow plastic hollow boards of various thicknesses.

[0005] However, it has certain drawbacks: it can only clean one plastic hollow board at a time. After cleaning one plastic hollow board, it is necessary to loosen the clamping component and then replace it with another plastic hollow board. It cannot clean multiple plastic hollow boards at the same time, so its waste removal efficiency needs to be improved. Utility Model Content

[0006] The purpose of this invention is to provide a waste removal device for the inner hole of a hollow plastic sheet, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A waste removal device for the inner hole of a hollow plastic sheet includes a waste removal platform. A support plate is placed at the rear end of the upper surface of the waste removal platform. A waste removal mechanism is provided on the upper surface of the support plate. A fixing mechanism is provided at the right end of the upper surface of the waste removal platform. The fixing mechanism includes a fixing frame. A threaded rod is movably connected through the upper surface of the fixing frame. A bearing sleeve is installed at the lower end of the threaded rod. A pressure plate is threadedly connected to the outside of the threaded rod inside the fixing frame. A lifting mechanism is provided on the rear surface of the support plate.

[0009] As a further embodiment of this utility model: the waste removal mechanism includes a fan, a first air duct is installed at the air outlet of the fan, a second air duct is installed at the front end of the first air duct, and a plurality of third air ducts are installed on the front surface of the second air duct from left to right.

[0010] As a further embodiment of this utility model: the lifting mechanism includes a mounting plate, a motor is mounted on the rear surface of the mounting plate, a first synchronous pulley is mounted on the output end of the motor, a second synchronous pulley is rotatably connected to the front surface of the mounting plate, a synchronous belt is mounted on the outside of the first and second synchronous pulleys, and two mounting rods are mounted on the front surface of the mounting plate to the right of the first and second synchronous pulleys, and a mounting block is movably connected to the outside of the two mounting rods.

[0011] As a further embodiment of this utility model: the lower end of the fixing frame and the bearing sleeve are both installed on the upper surface of the waste removal platform, and the pressure plate is slidably connected to the inner front and rear surfaces of the fixing frame.

[0012] As a further embodiment of this utility model: the fan is installed on the upper surface of the support plate, and the first air duct and the third air duct are both connected to the interior of the second air duct.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model has a fixing mechanism. By rotating the threaded rod in the fixing mechanism, the pressure plate is driven to descend, which can fix multiple hollow plastic sheets stacked together, thereby facilitating the simultaneous cleaning of the holes in multiple hollow plastic sheets.

[0016] 2. This utility model is equipped with a lifting mechanism. The motor in the lifting mechanism drives the synchronous belt to rotate through the first synchronous pulley and the second synchronous pulley, thereby driving the mounting block to rise and fall, and in turn driving the waste cleaning mechanism to rise and fall. This facilitates the cleaning of the holes of multiple stacked hollow plastic boards, avoiding the need to clean one hollow plastic board at a time, thus greatly improving the cleaning efficiency.

[0022] Please see Figure 1 and Figure 2 In this embodiment of the utility model, a waste removal device for the inner hole of a hollow plastic board includes a waste removal platform 1. A support plate 2 is placed on the rear end of the upper surface of the waste removal platform 1. A waste removal mechanism 3 is provided on the upper surface of the support plate 2. The waste removal mechanism 3 includes a fan 4. The fan 4 is installed on the upper surface of the support plate 2. A first air duct 5 is installed at the air outlet end of the fan 4. A second air duct 6 is installed at the front end of the first air duct 5. Multiple third air ducts 7 are installed from left to right on the front surface of the second air duct 6. The first air duct 5 and the third air ducts 7 are all connected to the interior of the second air duct 6.

[0023] The rear end of the upper surface of the waste removal platform 1, i.e. the installation position of the support plate 2, is lower than the placement position of the hollow plastic plate 21. This ensures that the distance between the third air duct 7 and the waste removal platform 1 is not too large, thus preventing the air from not reaching the holes of the hollow plastic plate 21.

[0024] The blower 4 draws air from the outside and sprays the air through the third air duct 7 to clean the holes of the hollow plastic sheet 21 and remove the waste.

[0025] exist Figure 1 , Figure 3 and Figure 4 In the middle: A fixing mechanism 8 is provided at the right end of the upper surface of the waste removal platform 1. The fixing mechanism 8 includes a fixing frame 9. A threaded rod 10 is movably connected through the upper surface of the fixing frame 9. A bearing sleeve 11 is installed at the lower end of the threaded rod 10. The lower end of the fixing frame 9 and the bearing sleeve 11 are both installed on the upper surface of the waste removal platform 1. A pressure plate 12 is threadedly connected to the outside of the threaded rod 10 on the inside of the fixing frame 9. The pressure plate 12 is slidably connected to the front and rear surfaces inside the fixing frame 9.

[0026] Multiple hollow plastic sheets 21 can be stacked vertically;

[0027] The bearing sleeve 11 includes a bearing housing and a bearing installed inside the bearing housing. The threaded rod 10 is installed inside the bearing, so the threaded rod 10 and the bearing sleeve 11 are rotatable relative to each other.

[0028] The rotation of the threaded rod 10 can drive the pressure plate 12 to rise and fall, thereby fixing the stacked hollow plastic plates 21 and preventing them from shifting due to airflow impact.

[0029] A lifting mechanism 13 is provided on the rear surface of the support plate 2. The lifting mechanism 13 includes a mounting plate 14. The lower end of the mounting plate 14 is mounted on the upper surface of the waste removal platform 1. A motor 15 is mounted on the rear surface of the mounting plate 14. A first synchronous pulley 16 is mounted on the output end of the motor 15. A second synchronous pulley 17 is rotatably connected to the front surface of the mounting plate 14. A synchronous belt 18 is mounted on the outside of the first synchronous pulley 16 and the second synchronous pulley 17. Two mounting rods 19 are mounted on the right side of the first synchronous pulley 16 and the second synchronous pulley 17 on the front surface of the mounting plate 14. A mounting block 20 is movably connected to the outside of the two mounting rods 19. The rear end of the mounting block 20 is mounted on the right side of the synchronous belt 18, and the front end of the mounting block 20 is connected to the rear surface of the support plate 2.

[0030] Motor 15 is connected to the forward and reverse circuit, which can drive synchronous belt 18 to rotate clockwise and counterclockwise. It also has a self-locking function, meaning that the motor shaft cannot rotate after power is cut off.

[0031] The synchronous belt 18 can drive the mounting block 20 to rise and fall, thereby driving the support plate 2 and the waste removal mechanism 3 to rise and fall, which facilitates the cleaning of the holes in the multiple stacked hollow plastic plates 21.

[0032] The working principle of this utility model is as follows: In use, multiple hollow plastic sheets 21 are stacked on the waste cleaning platform 1. Then, the threaded rod 10 is rotated to drive the pressure plate 12 to descend, and the pressure plate 12 fixes the multiple hollow plastic sheets 21. Next, the fan 4 is started to draw air from the outside, and the airflow passes through the first air duct 5, the second air duct 6, and finally sprays out through the third air duct 7. Then, the motor 15 drives the first synchronous wheel 16 to rotate counterclockwise, thereby driving the synchronous belt 18 to rotate counterclockwise, and then driving the mounting block 20 to rise. This drives the waste cleaning mechanism 3 to rise and clean the holes of the stacked hollow plastic sheets 21. After the mounting block 20 rises to the top, the motor 15 drives the first synchronous wheel 16 to rotate clockwise, thereby driving the mounting block 20, and then driving the waste cleaning mechanism 3 to descend and reset, and clean the holes of the hollow plastic sheets 21 again.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
