Description

Technical Field

[0001] This utility model belongs to the field of plastic hollow board processing technology, and more specifically, it relates to a plastic hollow board bending device. Background Technology

[0002] Hollow plastic sheets are lightweight and durable sheets made of polypropylene (PP). Their structure consists of two planar layers and a hollow lattice structure in the middle. This unique structure gives hollow sheets good strength, light weight, and sound insulation and heat insulation properties. Hollow plastic sheets are widely used in packaging, billboards, construction, transportation, and other fields.

[0003] Patent application number CN202321277458.2 discloses a plastic hollow board bending device, which solves the problem that some existing plastic hollow board bending devices cannot control the bending angle of the hollow board during the bending process, thus affecting the bending accuracy of the hollow board. It includes a fixed frame, a bending unit, a pointer, and a fixing unit. The fixed frame includes a fixed plate, a support plate, and a support box. The support plate is fixedly installed at the bottom of the fixed plate, and the support box is fixedly installed on the front and rear sides of the fixed plate. The bending unit is located on one side of the fixed plate and includes a flipping plate, a heating block, and a rotating rod. This plastic hollow board bending device can drive the flipping plate to rotate, enabling the flipping plate to bend the hollow board. By observing the pointer and angle scale lines, the hollow board can be bent to a specified angle, meeting the bending needs of most hollow boards. It can also clamp and fix the hollow board, keeping the horizontal and vertical directions of the hollow board flat and improving the bending accuracy. However, the above technical solution lacks a fixing and traction device for the plastic hollow board, which causes the plastic hollow board to easily shift or tilt when placed on the worktable, affecting the bending effect. It is also prone to errors when adjusting the bending length.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a plastic hollow board bending device in order to achieve a more practical purpose. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example 1:

[0025] As attached Figure 1 To be continued Figure 4 As shown: This utility model provides a plastic hollow board bending device, including a worktable 1, a heating mechanism 2, a pressing mechanism 3, and a bending mechanism 4. The structure and operation of the heating mechanism 2 are the same as those disclosed in patent application CN202120138523.8, and it is used to heat a designated position on the plastic hollow board. The heating mechanism 2 is installed at the middle position of the top of the worktable 1. The pressing mechanism 3 is installed at the top of the worktable 1 near the heating mechanism 2. The bending mechanism 4 is installed on one side of the worktable 1 near the pressing mechanism 3. The pressing mechanism 3 and the bending mechanism 4 are the same as those disclosed in patent application CN202321277458.2, and they are used for fixing and bending the plastic hollow board. A first sliding groove 5 is provided on one side of the top of the worktable 1. A first slider 6 is slidably installed in the first slide groove 5. The movement of the first slider 6 realizes the conveying of the clamped plastic hollow board. A first mounting seat 7 is installed at the top of the first slider 6. A second slide groove 8 is provided on one side of the first mounting seat 7. A pair of second sliders 9 are slidably installed on both sides of the second slide groove 8. A pair of clamping plates 10 are symmetrically installed on one side of the pair of second sliders 9. The movement of the pair of clamping plates 10 realizes the fixing and loosening of the plastic hollow board. A first drive assembly is installed in the first slide groove 5 to drive the first slider 6 to move. A second drive assembly is installed in the second slide groove 8 to drive the pair of second sliders 9 to move. A dust collection assembly is installed on one side of the worktable 1 near the heating mechanism 2 to remove and adsorb the dust and debris accumulated on the surface of the plastic hollow board.

[0026] The first drive assembly includes a first screw 11, which passes through the front and rear sides of the first slider 6 and is threadedly connected to the first slider 6.

[0027] The first motor 12 is installed on one side of the workbench 1, and the output end of the first motor 12 is connected to the first screw 11 via a coupling.

[0028] The first motor 12 drives the first screw 11 to rotate. Under the limiting action of the first slide groove 5, the first slider 6 moves and drives the first mounting base 7 to move, thereby adjusting the position of the plastic hollow plate.

[0029] The second drive assembly includes a bidirectional screw 13, which passes through the left and right sides of a pair of second sliders 9 and is threadedly connected to the pair of second sliders 9.

[0030] The first mounting base 7 has a second motor 14 mounted on one side, and the output end of the second motor 14 is connected to the bidirectional screw 13 via a coupling.

[0031] The second motor 14 drives the bidirectional screw 13 to rotate. Under the limiting action of the second slide groove 8, a pair of second sliders 9 move towards or away from each other simultaneously, thereby fixing and releasing the plastic hollow plate.

[0032] The dust collection assembly includes a dust collection box 15, an air inlet 16 installed on one side of the dust collection box 15, and the air inlet 16 is located above the workbench 1. An antistatic device 17 is installed on the side of the air inlet 16 away from the heating mechanism 2. An air inlet pipe 18 is installed at the top of the dust collection box 15, and the other end of the air inlet pipe 18 is connected to the air inlet 16. A filter screen 19 is installed in the middle of the interior of the dust collection box 15. An air pump 20 is installed at the bottom of the interior of the dust collection box 15. An air outlet 21 is provided at the bottom of one side of the dust collection box 15, and the air outlet 21 is connected to the output end of the air pump 20.

[0033] The static electricity remover 17 removes static electricity from the surface of the plastic hollow board. When the air pump 20 is turned on, the air pump 20 discharges the air in the dust collection box 15, causing a negative pressure to be generated in the dust collection box 15 instantly. This causes the dust and debris on the surface of the plastic hollow board to enter the dust collection box 15 through the air inlet 16 and the air inlet pipe 18 with the airflow and be filtered by the filter screen 19.

[0034] The workbench 1 is equipped with a controller 22 on one side. The controller 22 is electrically connected to the first motor 12, the second motor 14, the static eliminator 17, the air pump 20, the heating mechanism 2 and the bending mechanism 4, respectively, so as to facilitate the control of the overall circuit of the device.

[0035] The working principle of this embodiment is as follows: When using the plastic hollow board bending device, the operator first connects the device to the power supply and sets the bending length and bending angle data of the plastic hollow board in the controller 22. After setting, the operator places the plastic hollow board between a pair of clamping plates 10 and turns on the second motor 14. The second motor 14 drives the bidirectional screw 13 to rotate. Under the limiting action of the second slide groove 8, a pair of second sliders 9 simultaneously clamp and fix the plastic hollow board. After fixing, the operator turns on the first motor 12. The first motor 12 drives the first screw 11 to rotate. Under the limiting action of the first slide groove 5, the first slider 6 moves and moves the plastic hollow board to below the heating mechanism 2. Heating is performed at the designated location. After heating is completed, the operator continues to control the movement of the plastic hollow board. During the movement, the air pump 20 is turned on, and the static electricity remover 17 removes static electricity from the surface of the plastic hollow board. When the air pump 20 is turned on, it discharges the air from the dust collection box 15, creating a negative pressure inside the dust collection box 15. This causes the dust and debris on the surface of the plastic hollow board to enter the dust collection box 15 through the air inlet 16 and the air inlet pipe 18 with the airflow and be filtered by the filter screen 19. Then, the operator controls the plastic hollow board to move to the position below the pressing mechanism 3 and presses the plastic hollow board through the pressing mechanism 3. After pressing, the operator opens the bending mechanism 4 to bend the plastic hollow board. Example 2:

[0036] Based on Example 1, as shown in the appendix Figure 1To be continued Figure 5 As shown: The pressing mechanism 3 includes a gantry frame 23, which is installed on one side of the top of the workbench 1. A pressing plate 24 is slidably installed on the inner side of the gantry frame 23. An electric telescopic rod 25 is installed on the top of the gantry frame 23. The bottom end of the output end of the electric telescopic rod 25 passes through the top of the gantry frame 23 and is slidably connected to the gantry frame 23. The bottom end of the output end of the electric telescopic rod 25 is connected to the pressing plate 24.

[0037] By extending the output end of the electric telescopic rod 25, the pressing plate 24 can move together and press against the surface of the plastic hollow board, thereby avoiding the need for manual control to press the pressing plate 24 against the surface of the plastic hollow board.

[0038] The working principle of this embodiment is as follows: When the first slider 6 moves the plastic hollow plate to the position below the pressing plate 24, the controller 22 controls the electric telescopic rod 25 to extend, so that the pressing plate 24 presses on the surface of the plastic hollow plate. After bending, the electric telescopic rod 25 retracts, releasing the fixation of the plastic hollow plate, thereby improving work efficiency and reducing labor costs.

[0039] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
