Description

Technical Field

[0001] This invention is an intelligent shoe material cutting device, belonging to the field of cutting equipment. Background Technology

[0002] In the shoe upper production process, the vibrating knife cutting technology achieves synchronous cutting of multiple layers of fabric with high-frequency vibration, which significantly improves production efficiency. Its working principle is to complete the cutting action by the high-speed up and down vibration of the blade head. It adopts pneumatic drive and electric drive, and combines synchronous steering technology to accurately control the cutting path.

[0003] During the cutting process, the pressure plate device at the bottom continuously presses the fabric layer to ensure cutting accuracy. However, when the cutter head moves at high speed, the dynamic friction between the pressure plate and the fabric causes wrinkles on the fabric surface. These wrinkles can further cause interlayer misalignment, ultimately resulting in the fabric being scrapped. Summary of the Invention

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to represent selected embodiments of the invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] In the description of this invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0035] In existing cutting processes, the bottom-mounted pressure plate continuously presses down on the fabric layers to ensure cutting accuracy. However, during high-speed cutting, the dynamic friction between the pressure plate and the fabric causes wrinkles on the fabric surface. These wrinkles can further lead to interlayer misalignment, ultimately resulting in fabric failure. Therefore, to solve the above problems, this paper proposes the following technical solution:

[0036] Please see Figures 1 to 7This invention provides a technical solution for an intelligent shoe material cutting device: its structure includes a body 1, a moving platform 3 disposed on the surface of the body 1, and a cutting section 5 parallel to the upper surface of the moving platform 3. A control panel 2 for controlling the cutting section 5 and a projection device 4 is also installed on the side of the body 1. The cutting section 5 includes a cutting head 51 and a slide 52. The slide 52 cooperates with the transmission device of the body 1 through supports 53 disposed on both sides at the bottom. The cutting head 51 includes an auxiliary frame 511 and a cutting sleeve 512. The auxiliary frame 511 is mounted on the surface of the cutting sleeve 512, and a blade 515 is installed inside the cutting sleeve 512. The head 515 is connected to the carriage 52 via a surface-mounted movable stage 514. The auxiliary frame 511 includes a pressure ring 111 and a retainer 116. The pressure ring 111 is connected to a first adjusting arm 112. The first adjusting arm 112 drives the pressure ring 111 to rotate via a surface-mounted first adjusting motor 113. A second adjusting arm 115 is also mounted on one side of the first adjusting arm 112. The second adjusting arm 115 drives the first adjusting arm 112 to rotate via a second adjusting motor 114. The second adjusting arm 115 is mounted at the bottom of the retainer 116 and its movement is controlled by a third adjusting motor 117 on the surface of the retainer 116.

[0037] When in use, the main structure of this device includes a body 1, a movable platform 3 on the top of the body 1, the movable platform 3 is a conveyor belt structure, the fabric is placed on the surface of the movable platform 3 for continuous cutting, a projection device 4 is set on the side of the body 1, the layout of the fabric can be pre-planned on the surface of the fabric through the projection device 4, the utilization rate of the fabric is higher during cutting through projection planning, and the movement of the cutting part 5 can be controlled by the control panel 2 on the side of the body 1, as well as the input of images to the projection device 4.

[0038] The structure of the cutting section 5 includes a cutting head 51, which is mounted on the surface of the slide 52 and slides in cooperation with the slide 52. A transmission structure, such as a rotating worm gear, is installed inside the housing of the slide 52. The transmission group is driven by a horizontal motor 55 to move the cutting head 51 horizontally. The wire harness used by the cutting head 51 is protected by a movable cable 54 to prevent the wire harness from getting tangled. The brackets 53 on both sides of the slide 52 are used to connect the machine body 1 for vertical movement.

[0039] The cutting head 51 cuts through the front blade 515. The drive rod 151 of the blade 515 uses airflow as the main power to pneumatically drive the bottom blade 155 to reciprocate and cut the fabric. To facilitate the replacement of the blade 155, the drive rod 151 is disassembled through the locking ring 152. A pressure plate 154 is set on the outside of the blade 155 to wrap and protect it. The pressure plate 154 provides downward pressure through the buffer spring 153, making it adhere to the surface of the fabric. During cutting, the rotary motor 513 on the surface of the cutting sleeve 512 on which the blade 515 is mounted drives the blade 515 to rotate. The first lifting motor 516 on the top of the moving table 514 controls the blade 515 to move up and down. A drill 517 for drilling is also set on the side of the cutting sleeve 512 to enrich the functions. When cutting quickly, the friction between the pressure plate 154 and the fabric increases, which makes the fabric prone to wrinkles and affects the yield of cut products.

[0040] This device is optimized by adding an auxiliary frame 511 at the bottom of the cutter head 515. The auxiliary frame 511 is equipped with a pressure ring 111, which covers the fabric surface and restricts the covered area to reduce tensile deformation. The pressure ring 111 is limited by a support arm formed by the first adjusting arm 112 and the second adjusting arm 115 at the top. When the third adjusting motor 117 on the surface of the retainer 116 controls the second adjusting arm 115 to move up and down, it can independently lift the pressure ring 111 to speed up the response. A second adjusting motor 114 and a first adjusting motor 113 are set at the joint between the second adjusting arm 115 and the first adjusting arm 112. By controlling the two motors, the range of motion of the pressure ring 111 is increased, and the second adjusting arm 115 is more flexible during cutting.

[0041] The bottom of the ring body 101 of the pressure ring 111 is chamfered to improve the flexibility of sliding and reduce resistance. The ring body 101 is connected to the auxiliary side plate 104 and is supported by the movable rod 102 and the top pressure ring 103 through the connection. The movable rod 102 is nested with a spring. The top pressure ring 103 engages with the toothed ring 105 installed at the bottom of the first adjusting arm 112. The surface of the toothed ring 105 is provided with external tooth grooves. When the ring body 101 is rotated by the driving force of the first adjusting motor 113, the protrusion inside the auxiliary side plate 104 and the groove on the surface of the toothed ring 105 vibrate, so that the ring body 101 can vibrate intermittently, thereby flattening the fabric surface, reducing resistance during lateral movement, and the pre-vibration makes the fabric layers adhere more tightly, making the cutting more even.

[0042] Side plates are also provided on the upper and lower surfaces of the pressure ring 103. The side plates cooperate with the grooves on the upper and lower surfaces of the toothed ring 105 to prevent the pressure ring 103 from rotating during operation and to make it more stable during movement.

[0043] A movable groove is provided at the connection between the retainer 116 and the second adjusting arm 115. The second adjusting arm 115 is nested in the movable groove of the retainer 116. The screw in the middle of the third adjusting motor 117 is engaged with the internal thread of the second adjusting arm 115. When the third adjusting motor 117 rotates, it controls the second adjusting arm 115 to move up and down for short-distance rapid lifting and lowering. When the second adjusting motor 114 rotates, the first adjusting arm 112 swings back and forth. When the first adjusting motor 113 rotates, the pressure ring 111 swings left and right, thereby separating from the blade 155 and working independently. The independent operation of the pressure ring 111 not only expands the leveling range but also further smooths the fabric, making the cutting smoother.

[0044] The improved device, through the cooperation of the ring body 101 and the top pressure ring 103, when driven to rotate by the first adjusting motor 113 and the second adjusting motor 114, can not only quickly move the ring body 101 to avoid affecting the cutter path of the second adjusting arm 115, but also the intermittent action between the top pressure ring 103 and the toothed ring 105 can drive the ring body 101 to shake at the movable shaft of the auxiliary side plate 104. When moving horizontally, it can flatten the fabric, and through a wide range of limiting, the fabric is cut more evenly.

[0045] The above description only outlines the basic principles and preferred embodiments of the present invention. Those skilled in the art can make many changes and modifications based on the above description, and these changes and modifications should fall within the protection scope of the present invention.

[0046] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
