Description

Technical Field

[0001] This utility model relates to the field of fixture technology, specifically a fixture for producing pearl cotton boxes. Background Technology

[0002] EPE foam is made of low-density polyethylene resin through physical foaming, producing countless independent air bubbles. It has the characteristics of heat preservation, water resistance and moisture protection. EPE foam boxes are widely used in the packaging of electronic appliances, instruments and meters. During the production of EPE foam boxes, clamps are used to hold the EPE foam boards and then weld them together after hot melting to form EPE foam boxes.

[0003] To improve the efficiency of EPE foam box production, existing technologies have made numerous improvements to EPE foam box production fixtures. For example, patent publication number CN219381688U discloses an EPE foam box production fixture. Its key technical points are: it includes two crossbeams on both sides, with a horizontal plate installed between the middle of the two crossbeams. Several clamping plates are installed on the horizontal plate. Each of the two crossbeams has a sliding rod at its lower part, with sliders slidably connected to both ends of the sliding rods. A mounting plate is connected to one side of each slider, and a moving plate is connected to the upper part of both mounting plates. It also includes a linkage shaft located at the lower part of one end of the crossbeam. A first gear is keyed to both ends of the linkage shaft, and a second gear is installed at the lower part of the other end of the crossbeam. A toothed belt drives between the first and second gears. A bent connecting plate is provided at the lower part of the mounting plate, and the connecting plate is fixedly connected to the toothed belt through a fixing plate. This utility model can achieve stable clamping and fixing, as well as pushing and welding, and saves resources through a single power output.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative document describes a process where several clamping plates are installed on a horizontal plate. During the production of EPE foam boxes, several EPE foam side panels are clamped onto the corresponding clamping plates, and the EPE foam side panels are then heat-fused and welded together to form the EPE foam box. However, in reality, the side panel thicknesses of various EPE foam box models differ. If EPE foam side panels of different thicknesses are clamped in the aforementioned comparative document, the clamping plates need to be reinstalled, which is quite troublesome. Therefore, there is an urgent need in the art to improve the EPE foam box production fixture to overcome the shortcomings of the prior art. Utility Model Content

[0031] Please see Figures 1-8A jig for producing pearl cotton boxes includes a processing box 1 with an open upper part. A fixed base 2 is fixedly installed at the middle of the upper part of the processing box 1. Two symmetrical first movable clamping plates 3 are slidably connected to the upper part of the processing box 1 and are located on opposite sides of the fixed base 2. The first movable clamping plates 3 are used to clamp first pearl cotton side plates 5. The upper part of the fixed base 2 is provided with several sets of clamping members. Each set of clamping members includes two symmetrical second movable clamping plates 6. The two second movable clamping plates 6 are used to clamp second pearl cotton side plates 7. A first driving unit 4 is provided on one side of the fixed base 2. The first driving unit 4 is used to simultaneously drive two of the second movable clamping plates 6 in the several sets of clamping members to face each other or move towards each other. The machining housing 1 has a second drive unit 8 on one side for simultaneously driving two first moving clamping plates 3 to move towards or away from each other. The machining housing 1 contains two hot-melt plates 9 adapted to the fixed base 2 for hot-melt welding. The two hot-melt plates 9 can move up and down and can move towards or away from each other. A main controller 10 is located on one side of the machining housing 1. The first drive unit 4 includes a first drive motor 11 fixedly installed on one side of the fixed base 2. A first sliding block 12 is fixedly installed on the lower side of the second moving clamping plate 6. A first sliding groove 13 adapted to the first sliding block 12 is opened on the upper part of the fixed base 2. A first sliding groove 13 is rotatably connected to the first sliding block 12 at one end. A first drive screw 14 is fixedly installed at one end of a drive motor 11. The first drive screw 14 is threadedly connected to several first sliding blocks 12. The second drive unit 8 includes two second drive motors 15 fixedly installed on one side of the processing box 1 and synchronized. A connecting seat 16 adapted to the cavity inside the processing box 1 is fixedly installed on the lower side of the first moving clamping plate 3. Second sliding blocks 17 are fixedly installed at both ends of the connecting seat 16. Second sliding grooves 18 adapted to the second sliding blocks 17 are opened on opposite side walls inside the processing box 1. A second drive screw 14, one end of which is fixedly installed to the output end of the second drive motor 15, is rotatably connected in the second sliding groove 18. Rod 19, the second drive screw 19 passes through the second sliding block 17 and is threadedly connected to it. A telescopic device 20 with telescopic effect is fixedly installed at the bottom of the processing box 1.

A third drive screw 24 threadedly connected to the third sliding block 22 is rotatably connected in the third sliding groove 23. A third drive motor 25 for driving the third drive screw 24 to rotate is fixedly installed at one end of the bearing seat 21.

[0032] The specific implementation method in this embodiment is as follows: When it is necessary to produce pearl cotton boxes, a suitable first drive screw 14 is selected according to the size of the second pearl cotton side plate 7 of the pearl cotton box to be produced. The threads on the side of the first drive screw 14 are custom-made, and the threads of the moving range of each pair of first sliding blocks 12 are symmetrical and opposite. When the first drive screw 14 rotates, the two first sliding blocks 12 on several sets of clamping members move towards or away from each other simultaneously. The first drive motor 11 is turned on by the main controller 10. The output end of the first drive motor 11 drives the first drive screw 14 to rotate. When the first drive screw 14 rotates, each pair of first sliding blocks 12 moves towards or away from each other, adjusting the distance between the two second moving clamping plates 6 in each set of clamping members to the distance between the second pearl cotton side plate 7 and the first drive motor 14. The size is adapted to the position. The first drive unit 4 can simultaneously drive the two second moving clamping plates 6 in each set of clamping parts to move towards or away from each other, which facilitates the adjustment of the distance between the second moving clamping plates 6, improves the applicability of the clamp, and makes it easy to adjust. The first pearl cotton side plate 5 is positioned and clamped in the first moving clamping plate 3. The telescopic device 20 is activated. The telescopic end of the telescopic device 20 drives the bearing seat 21 to rise. The bearing seat 21 drives the two hot melt plates 9 to rise. The two hot melt plates 9 are located on opposite sides of the fixed seat 2. The third drive motor 25 is activated. The output end of the third drive motor 25 drives the third drive screw 24 to rotate. The threads of the third drive screw 24 located in the third sliding groove 23 are symmetrical and opposite. The third drive screw 24 drives the two third sliding blocks 2. 2. Moving in opposite directions, the two hot-melt plates 9 are existing known technologies, each equipped with a heating device. The two hot-melt plates 9 heat-melt the sides of several second pearl cotton side panels 7. Subsequently, the third drive motor 25 drives the two hot-melt plates 9 to move in opposite directions, while simultaneously driving the support seat 21 to move downwards via the telescopic device 20. The second drive motor 15 is activated. The two second drive motors 15 are synchronous motors. The output end of the second drive motor 15 drives the second drive screw 19 to rotate. The threads of the second drive screw 19 located on the inner side of the second sliding groove 18 are symmetrical and opposite. When the second drive screw 19 rotates, it drives the two second sliding blocks 17 to move in opposite directions. The two second sliding blocks 17 drive the connecting seat 16 to move, and the connecting seat 16 drives the first moving clamp 3 to move. The first moving clamp 3 drives the second... One pearl cotton side plate 5 moves, and two first pearl cotton side plates 5 abut against the sides of several second pearl cotton side plates 7, maintaining this position for a specified time until the second pearl cotton side plates 7 and the first pearl cotton side plates 5 are welded together. Then, the second drive motor 15 is activated to drive two first moving clamping plates 3 to move back-to-back, completing the production of the pearl cotton box. The first drive motor 11 is programmable; when clamping the second pearl cotton side plates 7, it can drive two second moving clamping plates 6 in each set of clamping components to move back-to-back, making the distance between the two second moving clamping plates 6 slightly larger than the thickness of the second pearl cotton side plate 7, facilitating the placement of the second pearl cotton side plate 7 between the two second moving clamping plates 6. Then, the first drive motor 11 drives the two second moving clamping plates 6 to move towards each other.The second pearl cotton side plate 7 is clamped. After the pearl cotton box is welded, the two second moving clamping plates 6 can be moved back and forth by the first drive motor 11. This facilitates the removal of the welded pearl cotton box and the placement, clamping, and fixing of the second pearl cotton side plate 7, improving the efficiency of pearl cotton box production.

[0033] Example 2

[0034] Please see Figure 3 and Figure 6 This embodiment includes the above embodiment, and further includes: the first movable clamping plate 3 is provided with two positioning clamping plates 26 and adjusting plates 27 for clamping the first pearl cotton side plate 5. The position of the adjusting plate 27 can be adjusted within the first movable clamping plate 3. A limiting guide post 29 that penetrates the adjusting plate 27 is fixedly installed on one side of the positioning clamping plate 26. A spring 28 is sleeved on the side of the limiting guide post 29. An adjusting threaded rod 30 is threaded through and threaded to the opposite sides of the first movable clamping plate 3, one end of which is rotatably connected to the side of the adjusting plate 27. A limiting nut 31 is threadedly connected to the side of the adjusting threaded rod 30.

[0035] In this embodiment, the first pearl cotton side plate 5 is placed between two positioning clamping plates 26. Since the spring 28 has a pushing effect on the positioning clamping plates 26, it is convenient to clamp and position the first pearl cotton side plate 5. When it is necessary to clamp and position the first pearl cotton side plate 5 of different sizes, the position of the positioning clamping plate 26 can be adjusted by rotating the adjusting threaded rod 30. When the adjusting threaded rod 30 rotates, it drives the adjusting plate 27 to move. Then, the position of the adjusting threaded rod 30 is fixed by locking the limiting nut 31. The third sliding groove 23 of the limiting guide post 29 prevents the spring 28 from undergoing radial deformation and is used to connect the positioning clamping plate 26 and the adjusting plate 27. The elastic coefficient of the spring 28 is small, as long as it can fix the position of the first pearl cotton side plate 5.
