Description

Technical Field

[0001] The invention relates to the technical field of leather cutting devices, in particular to a process method for cutting leather textile materials. Background Art

[0002] Leather is animal fur that has been tanned, nitrated or treated in other ways to resist corruption and is relatively soft and supple when the weather is dry. The leather industry covers the main industries of leather making, shoemaking, leather clothing, leather goods, fur and their products, as well as the supporting industries of leather chemicals, leather hardware, leather machinery and auxiliary materials. When leather is used, it needs to be cut according to its specific needs. Manual cutting is time-consuming and labor-intensive. In order to speed up work efficiency and reduce the labor of workers, cutting machines came into being. Cutting machines are indispensable equipment in some light industries. According to traditional concepts, cutting machines are machines that use the force of machine movement to pressurize the knife die to punch non-metallic materials.

[0003] At present, many leathers on the market are still cut manually during the cutting process, which is not only troublesome, time-consuming and labor-intensive, but also inefficient. Although there are some leathers that are cut mechanically using cutting machines, the existing cutting methods do not position the leather during the cutting process of leather textile materials, which can easily cause the leather to become loose and wrinkled during the cutting process, thereby affecting the quality after cutting and failing to meet the needs of use. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a process method for cutting leather textile materials, which solves the problem that manual cutting of leather is not only troublesome, time-consuming and labor-intensive, but also inefficient. In addition, the existing cutting method does not position the leather during the cutting process of the leather textile material, which easily causes the leather to become loose and wrinkled during the cutting process, thereby affecting the quality after cutting and failing to meet the needs of use.

[0006] (II) Technical solution

[0007] To achieve the above objectives, the present invention is implemented through the following technical solutions: A process for cutting leather textile materials, specifically comprising the following steps:

[0008] Step A. Material selection and waste utilization:

[0009] Select leather textile material as the cutting raw material, set the number of stacking layers according to the demand, and select the same material of defective material to make 20 mm wide rectangular strips, the number of layers of the rectangular strips is consistent with the number of stacking layers of the leather textile material, and fit the length side and width side of the stacked leather textile material to the two sides of the inner wall of the 7-shaped process baffle at the top of the spreading table;

[0010] Step B. Leather stacking and laying:

[0011] First, rectangular strips made of waste are laid on a spreading table, and a plurality of rectangular strips are stacked to form a cuboid. The cuboid made of waste is used to replace the 7-shaped process baffle at the front end of the spreading table, and the leather textile material is pushed and pulled to make its length side and width side aligned with the two sides of the 7-shaped cuboid. After that, the rectangular strips made of waste are then used to cling to the other two sides of the leather textile material, so that the cuboid is clinging to the leather textile material.

[0012] Step C. Transport and adsorption:

[0013] The material laid out in step B is transported to the cutting area through the spreading table, and the spreading table moves toward the cutting area to transport the material to the lower end of the cutting device, and the vacuum adsorption device arranged at the lower end of the cutting platform at the lower end of the cutting device adsorbs the lower end of the transported material to complete the fixation;

[0014] Step D. Data input and formatting:

[0015] The specified graphics are input through the CAD drawing program in the microcomputer control cabinet, and the typesetting program is input to cut the leather textile materials;

[0016] Step E. Cutting and collecting:

[0017] After the graphics and layout dimensions are input, the automatic cutting mechanism and servo-driven circulation device are started through the microcomputer-controlled electric cabinet to enable cutting according to the graphics and layout dimensions. After cutting, the scraps and formed leather textile materials are classified and collected.

[0018] Preferably, the maximum height of the stacked layers of raw materials and rectangular strips in step A does not exceed the maximum height of the process baffle in step B, so as to avoid excessive stacking of raw materials, which causes the front and back sides of the raw materials to be unable to align with the two sides of the process baffle, resulting in uneven edges during cutting and cutting deformation due to edge collapse, thereby causing a large amount of waste and damage to raw materials.

[0019] Preferably, a plurality of the rectangular blocks form 7-shaped baffles between each other and are fixed on the four sides of the leather textile material respectively, and the maximum height thereof is 25 mm, thereby enabling the process baffle to have height limiting and position limiting functions.

[0020] Preferably, the servo-driven circulation device performs track-type motion via a slide rail frame, wherein the slide rail frame includes a fixed seat and a slide rod.

[0021] Preferably, the automatic cutting mechanism includes multiple drive motors, fixed rods and cutting mechanisms, and the servo-driven circulation device and the automatic cutting mechanism are electrically connected to a microcomputer-controlled electrical cabinet. The microcomputer-controlled electrical cabinet cooperates with the automatic cutting mechanism and the servo-driven circulation device to realize the production of leather textile materials with a variety of graphics and layout methods, thereby meeting more and wider needs.

[0022] Preferably, the spreading table in step B is supported by a support frame, wherein the support frame is composed of four supporting legs and a plate frame, and the plate frame is made of stainless steel. Among steel materials, stainless steel has the best resistance to chemical corrosion and electrochemical corrosion, second only to titanium alloy, and is heat-resistant, high-temperature-resistant, low-temperature-resistant and even ultra-low-temperature-resistant, and has the advantages of a smooth surface and easy cleaning.

[0023] (III) Beneficial effects

[0025] 1. The present invention provides a process method for cutting leather textile materials. Rectangular strips are arranged to make them close to both sides of the leather textile materials to avoid cutting deformation caused by 5 mm unevenness and edge collapse when the textile layers are laid. The process baffles arranged at the top and rear sides in the forward direction of the laying ensure that the edges of the two sides are neat. At the same time, the negative pressure vacuum equipment at the lower end is adsorbed to ensure the film is attached, and the typesetting program is input to cut the leather textile materials. Compared with the traditional edge reservation of 15 mm, under the equal condition of ensuring that the edge of the leather textile material is not deformed, the original edge surplus is reduced to 5 mm, thereby saving 5% of materials and increasing the utilization rate by 5%.

[0026] 2. The present invention provides a process method for cutting leather textile materials. The process method can save 5% of materials by using rectangular strips made of 7-shaped process baffles and defective materials. The CAD drawing program and typesetting program configured in the microcomputer-controlled electric cabinet can be adjusted according to actual needs to realize the production of leather textile materials with various graphics and typesetting methods, meet different needs, and have higher practicality.

[0027] 3. The present invention provides a process method for cutting leather textile materials. The process method uses a vacuum adsorption device at the lower end to cooperate with a rectangular strip composed of waste or inferior materials that is close to the side of the raw material to avoid the film laid at the upper end from forming a floating surface with a curve during vacuum adsorption, thereby improving the cutting accuracy and quality and ensuring a neat and flat cross-section.

[0036] Step D. Data input and formatting:

[0037] The specified graphics are input through the CAD drawing program in the microcomputer control cabinet, and the typesetting program is input to cut the leather textile materials;

[0038] Step E. Cutting and collecting:

[0039] After the graphics and layout size are input, the automatic cutting mechanism and servo-driven circulation device are started by the microcomputer-controlled electric cabinet to make them cut according to the graphics and layout size. After cutting, the scraps and formed leather textile materials are classified and collected. The servo-driven circulation device is controlled by the microcomputer-controlled electric cabinet to drive the automatic cutting mechanism to circulate back and forth.

The process baffle ensures that the edges of both sides are neat and has the function of limiting height and position. The 7-shaped process baffle and the rectangular strip made of defective materials are close to the leather textile material, which can save 5% of materials. The servo drive circulation device performs track-type movement through a slide rail frame. The slide rail frame includes a fixed seat and a slide rod. The slide rod is a servo drive. The circulation device provides a slide-type fixed track to enable it to operate in a specified direction. The automatic cutting mechanism includes multiple drive motors, a fixed rod and a cutting mechanism.
