Description

Technical Field

[0001] This utility model relates to the technical field of hole positioning equipment, specifically a hole positioning device for pearl cotton production. Background Technology

[0002] Pearl cotton, also known as polyethylene foam, is a new type of environmentally friendly packaging material. It has many advantages such as water and moisture resistance, shock absorption, sound insulation, heat insulation, good plasticity, high toughness, recyclability, environmental friendliness, and strong impact resistance. During the production process of pearl cotton, it is necessary to perform perforation treatment according to the application scope.

[0003] A search revealed a patent, CN219854979U, which discloses a stamping mechanism for EPE foam production. This mechanism solves the problem that after EPE foam is stamped and cut, waste material remains inside, requiring manual removal or the use of a waste removal machine, thus affecting work efficiency. The mechanism includes a support device, a stamping device, and a feeding device. The stamping device includes a cutter head mounting plate, on the bottom of which a stamping cutter head is fixedly mounted. The cutter head has through holes on both sides and a raised ring on its inner bottom. This device facilitates the fixed mounting of the stamping cutter head through the cutter head mounting plate. The through holes on both sides of the cutter head allow a pin mounting strip to pass through, controlling the pin to push out the waste material. The raised ring on the inner bottom of the cutter head helps to hold the waste material cut from the EPE foam, allowing it to be removed as the cutter head rises.

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

[0005] In practice, when drilling holes in EPE foam sheets, due to their light weight, it is necessary to position and fix the sheets. However, the aforementioned comparative documents lack a positioning structure for drilling holes in EPE foam sheets. Because EPE foam sheets are easily deformed, drilling holes in them may cause the sheets to shift. If the sheets shift during the drilling process, it may cause the entire sheet to crack, reducing the quality of the drilling process. Therefore, there is an urgent need in this field to improve the drilling and positioning device for EPE foam production to overcome the shortcomings of the existing technology. Utility Model Content

[0030] 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.

[0031] Please see Figures 1-7A perforation positioning device for EPE foam production includes a perforation frame 1, a placement plate 2 inside the perforation frame 1, and a plurality of perforation clearance openings 3 through the placement plate 2. A first telescopic device 26 with a telescopic effect and its telescopic end extending into the perforation frame 1 is fixedly installed on the upper part of the perforation frame 1. A first movable plate 4 is fixedly installed at the lower telescopic end of the first telescopic device 26. A second movable plate 5 is provided below the first movable plate 4. A plurality of first connecting posts 6 are fixedly installed between the second movable plate 5 and the first movable plate 4. A pressing positioning plate 7 capable of vertical movement is provided below the second movable plate 5. A plurality of perforation cutters 8 adapted to the perforation clearance openings 3 are fixedly installed on the lower part of the second movable plate 5. A plurality of perforation clearance openings 3 through the pressing positioning plate 7 are provided. A through-hole 9 adapted to the drilling tool 8 is provided. A first limiting rod 10 with a T-shaped cross section is fixedly installed on the upper part of the clamping and positioning plate 7. The upper end of the first limiting rod 10 passes through the second moving plate 5. A first spring 11 is fixedly installed between the second moving plate 5 and the first limiting rod 10. Several storage slots 12 are provided at the lower part of the clamping and positioning plate 7. An inclined push tension plate 13 is rotatably connected in the storage slot 12. An elastic plate 14 with elasticity is fixedly installed between the side of the push tension plate 13 and the inner side wall of the storage slot 12. Several rotating columns 23 with elasticity are embedded on the side of the push tension plate 13. The first moving plate 4 has clearance grooves 25 on opposite sides. The clearance grooves 25 are used to make way for the first limiting rod 10.

[0032] Specifically, when it is necessary to make holes in the EPE foam board, place the EPE foam board of the appropriate size on the upper part of the placement plate 2, so that the EPE foam board completely covers several opening clearance slots 3. Activate the first telescopic device 26. The telescopic end of the first telescopic device 26 drives the first moving plate 4 to move down. The first moving plate 4 drives the second moving plate 5 to move down through the first connecting column 6. The second moving plate 5 drives the first spring 11 to move down. The first spring 11 drives the first limiting rod 10 to move down. The first limiting rod 10 drives the pressing positioning plate 7 to move down, pushing the rotating column 23 on the tensioning plate 13 into contact with the EPE foam board, pushing the tensioning plate 13 to tilt. The tensioning plate 13 is pushed to rotate under pressure, and the elastic plate 14 is compressed. When the rotating column 23 rotates, it pushes the EPE foam board to tension until the tensioning plate 13 is pushed to tilt. 3. The plate is fully rotated into the storage groove 12, and the clamping positioning plate 7 is fully clamped on the upper part of the pearl cotton board. The clamping positioning plate 7 stops moving downward, and the second moving plate 5 continues to move downward, driving the hole-making cutter 8 to move downward. The hole-making cutter 8 continues to move downward to make holes in the pearl cotton board. By clamping and positioning the pearl cotton board by moving downward, the stability of the pearl cotton board is ensured when making holes in the pearl cotton board, thereby improving the quality effect after making holes in the pearl cotton board. At the same time, through several rotatable pushing tension plates 13, the laid pearl cotton board can be flattened within a limited range, further improving the quality after making holes in the pearl cotton board. After the opening is completed, the clamping positioning plate 7 is driven to reset in conjunction with the first spring 11, and the clearance groove 25 is used to make way for the first limit rod 10.

[0033] As a technical optimization of this utility model, a plurality of second telescopic devices 15 with telescopic effect are fixedly installed on the upper part of the first moving plate 4. The telescopic ends of the plurality of second telescopic devices 15 penetrate through the first moving plate 4 and a third moving plate 16 is fixedly installed between their ends. A plurality of second connecting posts 17 adapted to the position of the hole-opening tool 8 are fixedly installed at the lower end of the third moving plate 16. The second connecting posts 17 penetrate through the second moving plate 5 and extend into the interior of the hole-opening tool 8. A push plate 18 adapted to the interior of the hole-opening tool 8 is fixedly installed at one end of the second connecting post 17 located inside the hole-opening tool 8.

[0034] Specifically, after the second moving plate 5 moves down to the lowest position, several synchronous second telescopic devices 15 are activated. The telescopic ends of the second telescopic devices 15 drive the third moving plate 16 to move down. The third moving plate 16 drives several second connecting columns 17 to move down. The second connecting columns 17 drive the push plate 18 located in the hole-opening cutter 8 to move down. The push plate 18 pushes out the waste material after the pearl cotton board is holed in the hole-opening cutter 8, thereby improving the efficiency of hole-opening pearl cotton.

[0035] As a technical optimization of this utility model, the opposite sides of the perforated frame 1 are provided with several second limiting rods 19 with T-shaped cross sections, and the opposite sides of the perforated frame 1 are provided with insertion slots 20 adapted to the placement plate 2. The placement plate 2 is provided with several limiting holes 21 adapted to the ends of the second limiting rods 19, and a second spring 22 is fixedly installed between the side of the second limiting rods 19 and the side of the perforated frame 1.

[0036] Specifically, when the placement plate 2 needs to be installed, the second limiting rod 19 is pulled away from the hole frame 1. At this time, the second spring 22 is stretched, and the side of the placement plate 2 is inserted into the insertion slot 20. After both sides of the placement plate 2 are fully inserted into the insertion slot 20, the position of the limiting hole 21 is aligned with the end position of the second limiting rod 19. The second limiting rod 19 is released, and the second spring 22 retracts, causing the end of the second limiting rod 19 to be inserted into the limiting hole 21, which facilitates the installation or later replacement of the placement plate 2. It is worth noting that the first movable plate 4 is fixedly installed at the telescopic end position of the first telescopic device 26 by fasteners and other existing known technologies. Its entirety can be replaced according to the required hole size of the pearl cotton board.

[0037] As a technical optimization of this utility model, an inclined plate 24 located below the placement plate 2 is fixedly installed between the opposite side walls inside the perforated frame 1. The inclined plate 24 is inclined, and the waste material after the hole is opened falls onto the inclined plate 24 and is discharged through the inclined plate 24.
