Description

Technical Field

[0001] The utility model belongs to the technical field of hook and loop fastener production, in particular to a cutting machine for hook and loop fastener production. Background Art

[0002] Velcro is a commonly used connecting material on clothes. It has two sides, one side is small and soft fiber, round hair (LOOP), and the other side is harder bristles with hooks (HOOK). When the hook side and the hair side are pressed together, the bristles will hook the round hair and fasten the two together. Generally, the hook is on the top.

[0003] The general production process for hook and loop fasteners is as follows: 1. The raw yarn is first woven into a tape using a loom. 2. The semi-finished tape is dyed in various colors using a high-temperature dyeing machine. 3. The suede tape is first dyed, then brushed on a raising machine to create a curled surface, and then sizing to set the shape. 4. The hook surface is then sizing to set the shape. The monofilaments on the surface of the dyed tape are then cut uniformly and appropriately using an imported hook cutter, creating the hook-tight tape. 5. The tape is finally slit into the desired width using a slitting machine, cut to the desired length, and rolled into boxes. A tape cutter is a mechanical device that cuts products into tapes. It can be used in many aspects, such as cutting Velcro into tapes, so that the rolled Velcro is divided into multiple small sections. The current tape cutter makes the Velcro easily twisted and curled after cutting. The main reason is that the material contains static electricity. Therefore, in order to solve this problem, static electricity needs to be eliminated. Utility Model Content

[0004] The purpose of the utility model is to provide a cutting machine for the production of hook and loop fasteners in order to solve the above-mentioned technical problems, thereby reducing the twisting and curling of the hook and loop fasteners after cutting.

[0005] In view of this, the utility model provides a cutting machine for producing hook and loop fasteners, comprising a frame, on which are provided:

[0006] An unwinding roller, used for winding the hook and loop fastener to be cut;

[0007] A conveying roller, connected to a power source and capable of circumferential rotation, for conveying the hook and loop fastener unwound from the unwinding roller;

[0008] A longitudinal cutting assembly, which is used to longitudinally cut the hook and loop fastener into a plurality of strips;

[0009] A cross-cutting assembly, which is arranged behind the longitudinal cutting assembly and is used to cut multiple hook and loop fasteners into segments at the same time;

[0010] The static electricity removal device is arranged between the cross-cutting component and the longitudinal cutting component, and is used to remove static electricity from the Velcro.

[0011] In this technical solution, the static eliminator is used to eliminate static electricity in the Velcro and reduce the twisting and curling of the Velcro after cutting. The static eliminator is a common static eliminator on the market. The recommended model is NEOS12F. The working principle of the static eliminator is mainly based on the balance principle and the cancellation principle. The balance principle means that the static eliminator will transfer the charge from the charged body to the grounded body so that the charges of the two reach a balanced state. The cancellation principle is to eliminate static electricity by outputting a charge with the opposite polarity to the static electricity to meet with a charged body with the same polarity and cancel it out. Specifically, the static eliminator consists of a high-voltage power supply generator and a discharge electrode (generally made into an ion needle). The air is ionized into a large number of positive and negative ions through the high-voltage corona discharge at the tip, and then the wind blows a large number of positive and negative ions to the surface of the object to neutralize the static electricity, or the static eliminator is directly placed close to the surface of the object to neutralize the static electricity.

[0012] Furthermore, the longitudinal cutting assembly includes:

[0013] A longitudinal cutting frame, wherein the longitudinal cutting frame is provided with a slide rail;

[0014] The tool holder is provided in plurality and is arranged on the slide rail at intervals along the length direction of the slide rail, and each tool holder is fixedly provided with a longitudinal cutting knife.

[0015] In this technical solution, the longitudinal cutting knife can cut the Velcro longitudinally during the transmission process of the Velcro.

[0016] Furthermore, each tool holder is provided with a corresponding heating component, and the heating component is used to heat the Velcro before cutting.

[0017] In this technical solution, heat energy is used to soften the material of the hook and loop fastener before cutting, reducing its hardness and strength, thereby making the cutting process smoother.

[0018] Furthermore, the heating component includes a heating lamp tube, which is arranged above the Velcro transmission path, and a height adjustment component for adjusting the vertical distance from the heating lamp tube to the Velcro is provided on the tool holder.

[0019] Furthermore, the height adjustment component includes:

[0020] An adjusting cylinder, wherein the adjusting cylinder is fixedly mounted on the tool holder, and the piston rod of the adjusting cylinder is perpendicular to the transmission direction of the hook and loop fastener;

[0021] A connecting plate is fixedly arranged at the output end of the regulating cylinder, and the heating lamp is fixedly connected to the connecting plate.

[0022] In this technical solution, the height adjustment component can adjust the height of the heating lamp tube, that is, the vertical distance from the heating lamp tube to the Velcro, according to different batches of materials to adapt to different heating requirements and achieve the best effect of softening the Velcro material.

[0023] Furthermore, the cross-cutting assembly includes:

[0024] A fixing plate, the fixing plate being fixedly disposed below the transmission path of the hook and loop fastener for supporting the hook and loop fastener;

[0025] An upper blade is slidably disposed above the transmission path of the hook and loop fastener, and the upper blade is staggered with respect to the fixed plate;

[0026] The cross-cutting cylinder is fixedly arranged on the frame, and the piston rod of the cross-cutting cylinder is fixedly connected to the upper blade, which can drive the upper blade to move up and down to cut the Velcro.

[0027] Furthermore, a dust removal device is provided between the longitudinal cutting assembly and the cross-cutting assembly, and the dust removal device is used to remove dust and debris on the Velcro.

[0028] In this technical solution, the Velcro is cut with the bristles facing upwards, and the bristle surface is more likely to be stained with dust and debris. After the static electricity removal device removes static electricity from the Velcro, the adsorption force of the dust originally adsorbed on the Velcro under the action of the electrostatic force will be reduced. At this time, the dust on the Velcro can be removed by the dust removal device.

[0029] Furthermore, the dust removal device includes:

[0030] a first roller, the first roller being used for winding a clean sticky paper roll;

[0031] The second roller is used to roll up the used sticky paper, the bottom of the second roller contacts the Velcro, and the second roller is connected to the servo motor and can intermittently rotate circumferentially at a preset angle.

[0032] In this technical solution, when the servo motor is started, the second roller rotates to roll the clean sticky paper on the first roller onto the second roller, and then the servo motor stops. After the Velcro is destaticized, the sticky paper will pick up the dust on the Velcro when it passes under the second roller. After a certain period of time, there will be a lot of dust on the sticky paper in contact with the Velcro. At this time, the servo motor is started again to rotate the second roller by a certain angle, and the clean sticky paper roll on the first roller is unwound, and the section of paper with more dust on the second roller will be wound on the second roller, so that the clean sticky paper roll will come into contact with the Velcro again and get covered with dust, and this process is repeated.

[0033] Furthermore, a receiving tray is provided at the rear of the cross-cutting assembly.

[0034] Furthermore, the method of use includes the following steps:

[0035] S1: Install the hook and loop fastener to be cut onto the unwinding roller and extract part of the hook and loop fastener, passing it through the conveyor roller, longitudinal cutting assembly, static elimination device and cross-cutting assembly in sequence, and adjust the height of the heating lamp;

[0036] S2: Start the power source of the conveying roller and the cross-cutting cylinder to start the transmission of the hook and loop fastener, start the longitudinal cutting component to cut, start the static electricity removal device to remove static electricity, and start the dust removal device to remove dust.

[0037] The beneficial effects of the utility model are:

[0038] 1. The anti-static device is used to eliminate static electricity in the hook and loop fastener, reducing the twisting and curling of the hook and loop fastener after cutting. The slitting knife can cut the hook and loop fastener longitudinally during the conveying process.

[0039] 2. Before cutting the Velcro, use heat energy to soften the material of the Velcro, reduce its hardness and strength, and make the cutting process smoother.

[0040] 3. The height adjustment component can adjust the height of the heating lamp, that is, the vertical distance from the heating lamp to the Velcro, according to different batches of materials, to adapt to different heating requirements and achieve the best effect of softening the Velcro material.

[0041] 4. When cutting the Velcro, the bristles are facing upwards, and the bristle surface is more likely to be stained with dust and debris. After the static electricity removal device removes the static electricity from the Velcro, the adsorption force of the dust originally adsorbed on the Velcro under the action of the electrostatic force will be reduced. At this time, the dust on the Velcro can be removed by the dust removal device. BRIEF DESCRIPTION OF THE DRAWINGS
