Description

Technical Field

[0001] This utility model relates to the field of opening and closing fixtures, and in particular to a simple opening and closing disassembly fixture. Background Technology

[0002] A laminating machine is a widely used piece of equipment in the printing and packaging industries, primarily used to coat the surface of various materials with a protective or decorative film. This equipment uses hot or cold pressing to evenly adhere the film to substrates such as paper, cards, book covers, and advertising posters, enhancing the product's wear resistance, water resistance, and aesthetics, while also extending its service life.

[0003] In the process of disassembling laser-cut products and placing them on a laminating machine for lamination, the disassembly and placement processes often rely on manual operation. Since laser-cut workpieces are typically densely packed or nested, operators must individually separate the cut pieces and place them one by one onto the laminating machine's conveyor belt. This process is time-consuming, especially when there are many workpieces, complex structures, small sizes, or many irregular shapes. Manual disassembly efficiency is significantly reduced, severely restricting the overall production line's operating rhythm and capacity output. During manual disassembly and placement, workpieces inevitably come into contact with the operator's hands or other auxiliary tools, easily causing surface scratches, fingerprints, or dust adhesion. These defects are particularly noticeable on metal or polymer materials where high surface finish is required, directly affecting the product's appearance quality and customer satisfaction. Furthermore, due to the limited accuracy of manual positioning, the placement of workpieces on the laminating machine may deviate, leading to uneven adhesion, residual air bubbles, and edge lifting during lamination, thus affecting the flatness, adhesion, and overall aesthetics of the lamination.

[0004] Therefore, a simple opening and closing disassembly fixture needs to be designed to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the shortcomings of low efficiency in manual operation when disassembling laser-cut products and placing them on a laminating machine, especially for a large number of complex or small-sized workpieces, which is time-consuming, and the fact that workpieces are prone to contact with hands or other tools during manual disassembly, causing surface scratches and contamination, affecting appearance quality, and that limited manual positioning accuracy leads to uneven lamination, air bubbles, and edge lifting, affecting lamination quality and aesthetics, this utility model provides a simple opening and closing disassembly fixture.

[0006] The technical solution is as follows: A simple opening and closing piece-separation fixture includes a base, sleeves, fixed sleeves, rollers, a top cover, and torsion springs. Sleeves are fixedly connected to both sides of the left side of the base. Fixed sleeves are rotatably connected inside the two sleeves. Multiple rollers are rotatably connected to the corresponding sleeves along the axial direction between the two fixed sleeves. A top cover is fixedly connected between the two fixed sleeves. Torsion springs are connected to both sides between the top cover and the base.

[0007] Preferably, the base has multiple square slots in a rectangular array inside, and multiple protrusions are fixed in a rectangular array on the right side of the top cover, with each protrusion inserted into the corresponding square slot.

[0008] Preferably, the device also includes a fixing block and a lever, with the fixing block fixedly connected to the top of the cover and the lever fixedly connected to the left side of the fixing block.

[0009] Preferably, the device also includes a connecting rod, a top block, a screw, a knob, and an abutment block. The base is symmetrically and fixedly connected to two connecting rods. A top block is fixedly connected to one side of each of the two connecting rods on the same side. A screw is threadedly connected to the bottom of each connecting rod. A knob is fixedly connected to the bottom of each screw. An abutment block is rotatably connected to the top of each screw.

[0010] Preferably, all four knobs have anti-slip grooves arranged in a ring on the outside.

[0011] Preferably, it also includes mounting bases and magnets. Mounting bases are symmetrically fixedly connected to both sides of the base and the top cover. The four mounting bases on the same side are symmetrically distributed. Each mounting base has a magnet embedded and fixedly connected inside. Each magnet on each top cover is attracted to the corresponding magnet on the base.

[0012] The beneficial effects of this utility model are as follows: This utility model achieves rapid installation and fixation of the device on the laminating machine through the clamping structure between the connecting rod, top block, and abutment block, improving the applicability and ease of operation of the device; the rolling bearing structure composed of a sleeve, fixing sleeve, and multiple rollers effectively reduces the frictional resistance between rotating parts, making the opening and closing of the top cover easier and less strenuous; and the automatic pressing and separation of the workpiece cutting parts is achieved by the lever driving the top cover to rotate in conjunction with the torsion spring and protrusion, improving the efficiency and consistency of sheet removal; at the same time, the magnetic adsorption structure ensures stable fit of the top cover, enhancing operational safety. The overall structural design is reasonable, the operation is efficient and stable, and it reduces problems such as scratches and displacement caused by manual sheet removal.

[0018] Example: A simple opening and closing disassembly fixture, such as... Figures 1-4 As shown, it includes a base 1, a sleeve 2, a fixing sleeve 3, a roller 4, a top cover 5, a torsion spring 6, a fixing block 7, and a lever 8. The base 1 has six square slots arranged in a rectangular array inside. The right side of the top cover 5 has six protrusions fixed in a rectangular array, each protrusion being inserted into a corresponding square slot. Sleeves 2 are welded to the front and rear sides of the left side of the base 1. Fixing sleeves 3 are rotatably connected inside each of the two sleeves 2. Multiple rollers 4 are rotatably connected to the corresponding sleeves 2 along the axial direction between each of the two fixing sleeves 3. The top cover 5 is welded between the two fixing sleeves 3. Torsion springs 6 are connected to the front and rear sides of the top cover 5 and the base 1. A fixing block 7 is welded to the top of the top cover 5. A lever 8 is welded to the left side of the fixing block 7.

[0019] like Figure 1 and Figure 4 As shown, it also includes connecting rods 9, top blocks 10, screws 11, knobs 12, and abutment blocks 13. Two connecting rods 9 are welded symmetrically on both sides of the base 1. Top blocks 10 are welded to the side of the two connecting rods 9 on the same side that are close to each other. Each connecting rod 9 is threadedly connected to a screw 11 at its bottom. A knob 12 is welded to the bottom of each screw 11. Anti-slip grooves are arranged in a ring on the outer surface of the four knobs 12. The anti-slip grooves increase the friction between the fingers and the surface of the knobs 12, ensuring a good grip even when the hands are wet or gloves are worn, and preventing slippage. An abutment block 13 is rotatably connected to the top of each screw 11.

[0020] like Figure 1 and Figure 4 As shown, it also includes a mounting base 14 and a magnet 15. Mounting bases 14 are symmetrically welded to the upper and lower sides of the base 1 and the upper cover 5. The four mounting bases 14 on the same side are symmetrically distributed. Each mounting base 14 has a magnet 15 embedded inside. Each magnet 15 on the upper cover 5 is attracted to the corresponding magnet 15 on the base 1.

[0021] When the device is needed, first place the connecting rod 9 on the worktable of the laminating machine and limit and fix it by the top block 10. Then, rotate the knob 12 to drive the screw 11 to rotate, thereby driving the abutment block 13 to move upward along the guide rail until it is in close contact with the frame of the laminating machine. At this time, the top block 10 and the abutment block 13 together form a clamping structure, so that the entire device is installed on the laminating machine. Next, the operator pulls the film to the bottom of the base 1 and places the workpiece to be delaminated on the base 1. Then, press the lever 8 to make the fixing block 7 drive the upper cover 5 to rotate clockwise. During the rotation, the rolling bearing structure composed of the sleeve 2, the fixing sleeve 3 and multiple rollers 4 begins to play its role. When the upper cover 5 is subjected to radial load and begins to rotate, multiple rollers 4 roll between the sleeve 2 and the fixing sleeve 3. Since the rolling friction is much less than the sliding friction, the operator needs less effort to rotate the upper cover 5.

[0022] During this process, the torsion spring 6 deforms, and the protrusion at the bottom of the upper cover 5 presses the cut part in the workpiece into the square groove below, causing it to detach from the base 1 and fall onto the film layer of the laminating machine. After pressing, the two magnets 15 installed between the upper cover 5 and the base 1 attract each other, making the upper cover 5 stably adhere to the surface of the base 1. The operator pushes the upper cover 5 backward with a little force to further enhance the magnetic attraction effect. Then, the lever 8 is released, and under the action of the torsion spring 6, the upper cover 5 automatically rotates back to the initial position. At this time, the sheet material that has been delaminated can be taken out from the base 1, completing one delamination operation. If a new workpiece needs to be delaminated, the above steps can be repeated to continue the operation. If the device needs to be removed, simply rotate the knob 12 in the opposite direction to make the screw 11 drive the abutment block 13 to move downward and detach from the frame of the laminating machine, and the entire device can be easily removed from the laminating machine.
