Description

Technical Field

[0001] The present invention belongs to the technical field of Velcro production, and in particular relates to a cutting device for Velcro production and a use method thereof. Background Art

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

[0003] The general production process of Velcro products is as follows: 1. First, the loom will make the raw yarn into a ribbon shape through the weaving machine. 2. The semi-finished ribbon is dyed into various colors by high-temperature dyeing equipment. 3. The velvet ribbon of the Velcro is first dyed, and then the velvet surface of the color ribbon is brushed with curling machine equipment, and then it is sizing and shaping. 4. The hook surface is to size and shape the dyed ribbon hook surface, and then the monofilament on the surface of the ribbon is cut evenly and appropriately by the imported hook cutting machine to form a ribbon with hook stickiness. 5. The Velcro ribbon is finally divided into various specifications and widths by the tape cutting machine. Then it is cut to the required 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 can be divided into multiple small sections. The Velcro of current tape cutters is prone to twisting and curling after cutting. The main reason is that the material carries static electricity. Therefore, in order to solve this problem, static electricity needs to be eliminated. Summary of the invention

[0004] The purpose of the present invention is to provide a cutting device for Velcro production and a method of using the same in order to solve the above-mentioned technical problems, thereby achieving the effect of reducing the twisting and curling of the Velcro after cutting.

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

[0006] An unwinding roller, the unwinding roller is used to wind up the hook and loop fastener to be cut;

[0007] A conveying roller, the conveying roller is connected to a power source and can rotate circumferentially to convey the hook and loop fastener unwound from the unwinding roller;

[0008] A longitudinal cutting component, 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 a plurality of 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 charges with opposite polarity to the static electricity to meet and cancel out the charged body with the same polarity. Specifically, the static eliminator consists of a high-voltage power 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 a high-voltage corona discharge at the tip, and then a large number of positive and negative ions are blown to the surface of the object with wind 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] Further, the longitudinal cutting assembly comprises:

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

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

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

[0016] Furthermore, a heating component is correspondingly arranged on each tool holder, 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 Velcro before cutting, thereby 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 transmission path of the Velcro, and a height adjustment component for adjusting the vertical distance from the heating lamp tube to the Velcro is arranged on the tool holder.

[0019] Furthermore, the height adjustment component includes:

[0020] An adjusting cylinder, wherein the adjusting cylinder is fixedly arranged 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 tube 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, so as to adapt to different heating requirements and achieve the best effect of softening the Velcro material.

[0023] Further, the cross-cutting assembly comprises:

[0024] A fixing plate, the fixing plate is fixedly arranged below the transmission path of the hook and loop fastener to support the hook and loop fastener;

[0025] An upper blade, wherein the 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 fixing 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 easily stained with dust and debris. After the anti-static 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, and the dust on the Velcro can be removed by the dust removal device.

[0029] Furthermore, the dust removal device comprises:

[0030] A first roller, the first roller is used to roll up a clean dust-sticking paper roll;

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

[0032] In the present technical scheme, 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. When the Velcro is destaticized and transmitted under the second roller, the sticky paper will pick up the dust on the Velcro. 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 on the first roller is unwound for a section, 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 be in contact with the Velcro again and get covered with dust, and this process is repeated.

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

[0034] Further, the method of use comprises the following steps:

[0035] S1: Install the hook and loop fastener to be cut on the unwinding roller and extract part of the hook and loop fastener so that it passes through the conveying roller, the longitudinal cutting assembly, the static electricity removal device and the cross-cutting assembly in sequence, and adjust the height of the heating lamp tube;

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

[0037] The beneficial effects of the present invention are:

[0038] 1. The anti-static device is used to eliminate static electricity in the Velcro and reduce the twisting and curling of the Velcro after cutting. The longitudinal cutter can cut the Velcro longitudinally during the transmission process.

[0039] 2. Before cutting the Velcro, use heat energy to soften the Velcro material, 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 tube, that is, the vertical distance from the heating lamp tube to the Velcro according to different batches of materials, so as to adapt to different heating requirements and achieve the best effect of softening the Velcro material.

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