Description

Technical Field

[0001] The invention relates to the technical field of strip cutting machines, in particular to an automatic vertical and horizontal lace strip cutting machine for weft knitted fabrics. Background Art

[0002] The automatic vertical and horizontal lace slitting machine for weft knitted fabrics is an advanced equipment specially used for lace slitting of weft knitted fabrics. In the modern textile industry, the demand for processing weft knitted fabrics is growing, and high-quality lace slitting can add unique decorative effects to the fabrics and enhance the added value of the products. The equipment has a high degree of automation, which can greatly improve production efficiency and reduce the tediousness and errors of manual operations. At the same time, through precise control and advanced technology, it can achieve high-quality cutting effects, making the lace lines more neat and beautiful. In addition, the equipment has strong stability and reliability, can operate stably for a long time, and reduce maintenance costs;

[0003] Existing automatic vertical and horizontal lace slitting machines for weft knitted fabrics usually consist of multiple parts, including a feeding device, a cutting device, a clamping device, etc. The feeding device is responsible for smoothly conveying the weft knitted fabric to the cutting area, the cutting device cuts the fabric with a specific cutter, and the clamping device is used to fix the fabric to ensure the stability of the cutting process. When working, the weft knitted fabric is first placed on the feeding device, and the feeding device conveys the fabric to the cutting area. Then, the clamping device fixes the fabric, and the cutting device starts working to cut the fabric. After the cutting is completed, the feeding device continues to convey the fabric for the next round of cutting operation;

[0004] However, when cutting the fabric, the traditional automatic vertical and horizontal lace slitting machine for weft knitted fabrics usually clamps and fixes the two sides of the fabric. Although this fixing method can prevent the fabric from moving in the lateral direction to a certain extent, it is difficult to effectively guarantee the stability of the middle area of ​​the fabric. In the actual cutting process, the force between the cutting head and the fabric will cause the fabric to deform and displace to a certain extent. Due to the lack of sufficient support and fixation in the middle area, it is easy to move under the action of the cutting head. This movement will not only cause uneven cutting lines and affect the aesthetics of the product, but also cause deviations in the cutting size and reduce the quality of the product. Therefore, an automatic vertical and horizontal lace slitting machine for weft knitted fabrics is proposed to solve the above problems. Summary of the invention

[0005] In order to make up for the above shortcomings, the present invention provides an automatic vertical and horizontal lace cutting machine for weft knitted fabrics, which aims to improve the problem that traditional equipment usually clamps and fixes the two sides of the fabric, resulting in poor stability in the middle area.

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Reference Figure 1 - Figure 3 , an embodiment provided by the present invention: an automatic vertical and horizontal lace cutting machine for weft knitted fabrics, comprising a bottom plate 1, a support seat 2 5 is fixedly connected to the top of the bottom plate 1, the support seat 2 5 is made of solid cast iron material, and the surface is finely polished and smooth, a fixed block 1 7 is fixedly connected to the top of the support seat 2 5, a telescopic cylinder 8 is fixedly connected inside the fixed block 1 7, and a connecting shell 9 is fixedly connected to the output end of the telescopic cylinder 8, the connecting shell 9 is made of aluminum alloy, has light weight and high strength, and its internal structure is reasonably designed to effectively transmit power, a cutting head 17 is arranged inside the connecting shell 9, a replacement assembly is arranged on one side of the cutting head 17, and the replacement assembly is used for quickly replacing the cutting head 17, and a stabilizing assembly is arranged on the outer wall of the cutting head 17, and the stabilizing drum assembly is used for clamping and fixing the fabric;

[0034] The stabilizing component includes a plurality of rubber rollers 11, which are made of high-quality wear-resistant rubber and have good elasticity and friction. The rubber rollers 11 are arranged on the outer wall of the cutting head 17, and the rubber rollers 11 are rotatably connected with fixed blocks 2 12 inside, and one side of the fixed blocks 2 12 is fixedly connected with connecting blocks 13, which are made of aluminum alloy and have good strength and toughness. The connecting blocks 13 are rotatably connected with connecting plates 14 inside, and the outer walls of the connecting plates 14 are rotatably connected with sliders 15, which are made of wear-resistant plastic material with a smooth surface and can slide smoothly in a specific track. The sliders 15 on both sides are slidably connected with limit rods 16 inside, and the limit rods 16 are fixedly connected to the inner wall of the connecting shell 9. A spring 10 is fixedly connected between the sliders 15 on both sides, and one side of the support seat 2 5 is fixedly connected with the support seat 1 2, one side of the support seat 2 is rotatably connected with the fabric shaft 3, and the other side of the support seat 2 is rotatably connected with the guide shaft 4, and the top of the bottom plate 1 is fixedly connected with a collection box 6.

[0035] Specifically, in the process of the equipment cutting the fabric, the output end of the telescopic cylinder 8 is used to push the connecting shell 9 to slide on the top of the support seat 2 5. When the connecting shell 9 slides under the drive of the telescopic cylinder 8, it will drive the cutting head 17 to accurately cut the fabric. When the cutting head 17 moves, it will drive the rubber roller 11 to push the fabric to fit the outer wall of the support seat 1 2. When the rubber roller 11 contacts the outer wall of the support seat 1 2, it will be subjected to the reaction force from the outer wall of the support seat 1 2. This reaction force will push the connecting block 13 to move through the fixed block 2. When the connecting block 13 moves, When the connecting plate 14 moves, it will drive the connecting plate 14 to rotate. When the connecting plate 14 rotates, it will cause the sliders 15 on both sides to move to the opposite side. The movement of the sliders 15 will compress the spring 10. The rebound characteristic of the spring 10 is used to rebound the compression force, thereby increasing the squeezing force of the outer wall of the rubber roller 11 on the surface of the fabric. At the same time, the connecting shell 9 will also drive the rubber roller 11 to roll on the fabric while moving, thereby enhancing the stability of the cutting head 17 on the fabric cutting area, preventing the fabric position from moving, and enhancing the cutting effect of the equipment on the fabric.

[0036] Reference Figure 1 and Figure 4The replacement component includes a truncated cone block 18, which is fixedly connected to the outer wall of the cutting head 17. The outer wall of the truncated cone block 18 is provided with a special-shaped block 19. The special-shaped block 19 is made of high-strength engineering plastic and has a special shape design. It can be closely matched with the truncated cone block 18 to achieve fixed positioning. An angled slide groove 20 is opened inside the special-shaped block 19. The outer wall of the truncated cone block 18 is provided with a connecting block three 27. The connecting block three 27 is fixedly connected to the outer wall of the connecting shell 9. The outer wall of the connecting block three 27 is slidably connected with a connecting block two 24. The connecting block two 24 is made of high-strength plastic material and has good toughness and wear resistance. The surface of the connecting block 24 is designed with anti-skid patterns, which is convenient for operators to grasp and apply force. The inner wall of the connecting block 24 is fixedly connected with a plurality of slide bars 21, which are made of wear-resistant alloy steel and have a smooth surface, and can slide smoothly in the beveled slide groove 20. The slide bar 21 is slidably connected to the inner wall of the beveled slide groove 20. A spring 23 is fixedly connected to one side of the connecting block 24, and a fixed block 3 22 is fixedly connected to one side of the spring 23. The fixed block 3 22 is fixedly connected to the outer wall of the connecting block 3 27. A baffle 25 is arranged on one side of the truncated table block 18. The baffle 25 is made of a thick aluminum alloy plate, has a certain strength and weight, and can effectively block the movement of the cutting head 17. A latch 26 is slidably connected inside the baffle 25. The latch 26 is made of high-strength stainless steel, and the surface is finely polished, smooth and strong. The head of the latch 26 is designed with a ring structure that is easy to grasp, which is convenient for operators to plug and unplug. The latch 26 is slidably connected to the inside of the connecting block 3 27.

[0037] Specifically, in the process of replacing the cutting head 17, first, when the operator moves the pin 26 out of the baffle plate 25 and the connecting block three 27, the baffle plate 25 loses the fixing effect of the pin 26, and the baffle plate 25 without the fixing of the pin 26 can be smoothly moved out of the connecting block three 27, thereby providing space for the movement of the cutting head 17. Next, the operator pulls the connecting block two 24. When the connecting block two 24 is pulled, the spring two 23 will be driven to rebound. At the same time, the movement of the connecting block two 24 will also cause the slide bar 21 to slide inside the angled slide groove 20. As the slide bar 21 slides, the special-shaped blocks 19 on both sides will be moved out from the outer wall of the truncated cone block 18. When the truncated cone block 18 loses the blocking effect of the special-shaped block 19, the operator can smoothly pull the cutting head 17 out from the inside of the connecting shell 9. In the process of installing another cutting head 17, the special-shaped block 19 is used to fix one side of the truncated cone block 18 in the same way. During the installation process, the special-shaped block 19 can be accurately inserted into the specific position of the truncated cone block 18 to ensure firm fixation. At the same time, the baffle 25 is used to fix the other side of the truncated cone block 18, thereby realizing the rapid installation of the cutting head 17 and improving the efficiency of replacing the cutting head 17 of the equipment.

[0038] Working principle: When the equipment is cutting the fabric, the output end of the telescopic cylinder 8 is used to drive the connecting shell 9 to slide on the top of the support seat 2 5, thereby driving the cutting head 17 to cut the fabric. While the cutting head 17 is moving, it will drive the rubber roller 11 to push the fabric to fit the outer wall of the support seat 2. During this process, the rubber roller 11 will be subjected to the reaction force from the outer wall of the support seat 2, thereby pushing the connecting block 13 to move through the fixed block 2 12. While the connecting block 13 is moving, it will drive the connecting plate 14 to rotate, causing the sliders 15 on both sides to move to the opposite side, thereby compressing the spring 10. The rebound characteristics of the spring 10 are used to rebound this compression force, thereby increasing the squeezing force of the outer wall of the rubber roller 11 on the surface of the fabric. While the connecting shell 9 is moving, it will also drive the rubber roller 11 to roll on the fabric, thereby enhancing the stability of the cutting area of ​​the fabric by the cutting head 17 and preventing the fabric position from moving, making it difficult to In order to achieve a good cutting effect, the cutting effect of the equipment on the fabric is enhanced. In the process of replacing the cutting head 17, the pin 26 is first moved out from the baffle plate 25 and the connecting block three 27. The baffle plate 25 loses the fixing effect of the pin 26, so that it can be smoothly moved out from the connecting block three 27, providing space for the cutting head 17 to move. Then the connecting block two 24 is pulled, thereby driving the spring two 23 to rebound and the slide bar 21 to slide inside the bevel slide groove 20, so that the special-shaped blocks 19 on both sides are moved out from the outer wall of the truncated cone block 18. When the truncated cone block 18 loses the locking effect of the special-shaped block 19, the cutting head 17 can be smoothly pulled out from the connecting shell 9. In the process of installing another cutting head 17, the special-shaped block 19 is used to fix one side of the truncated cone block 18, and the baffle plate 25 is used to fix the other side of the truncated cone block 18, thereby realizing the installation of the cutting head 17 and improving the efficiency of the equipment in replacing the cutting head 17.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
