Description

Technical Field

[0001] This utility model relates to a cutting device for leather processing, belonging to the field of leather cutting and processing technology. Background Technology

[0002] With the rapid development of the leather industry and the diversification of product demands, traditional manual cutting or low-precision mechanical cutting methods can no longer meet the requirements of efficient and high-quality production. Therefore, modern leather processing equipment has gradually introduced automated and precision cutting technologies. Currently, leather cutting devices commonly employ CNC technology and servo drive systems, achieving precision and automated control in cutting. By intelligently adjusting parameters such as the angle, pressure, and speed of the cutting tools, these devices can adapt to leathers of different thicknesses and materials, improving production efficiency while ensuring cutting quality.

[0003] Authorization announcement number (CN222349032U) discloses a cutting device for leather processing, including a base and multiple support columns, each of which is fixedly connected to the base. The device also includes a pressing assembly, a transmission assembly, and a processing assembly. The pressing assembly includes a support seat, a slider, a rotating shaft, and a pressing roller. Two support seats are fixedly connected to the base, two sliders are slidably connected to the support seats, the rotating shaft is rotatably connected to the sliders and located between the two sliders, the pressing roller is fixedly connected to the rotating shaft, the transmission assembly is connected to the support seats, and the processing assembly is connected to the support seats. This invention solves the problem that, in the use of a leather processing cutting device, the leather needs to be rolled flat each time it is cut, resulting in reduced leather processing efficiency. In summary, the aforementioned leather processing cutting device lacks a blade replacement component, which may prevent quick replacement when blades wear or become damaged, impacting production efficiency. When blades wear down to a certain extent and cannot be replaced promptly, the cutting effect will deteriorate, edges will become rough, and damage to the leather surface may even occur, affecting the quality of the finished product. Furthermore, frequent downtime and manual adjustments increase production interruption time, reducing overall production efficiency and equipment utilization.

[0004] Therefore, a cutting device for leather processing is proposed. Utility Model Content

[0005] In view of this, the present invention provides a cutting device for leather processing to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial alternative.

[0006] The technical solution of this utility model is achieved as follows: a cutting device for leather processing, comprising: A cutting assembly includes a workbench, a first U-shaped plate fixedly installed on the top left side of the workbench, a cylinder fixedly installed on the top of the first U-shaped plate, an output plate fixedly connected to the output end of the cylinder, a housing provided at the bottom of the housing, and the top of the housing threadedly connected to the housing by multiple fastening screws. A leveling assembly includes a second U-shaped plate, which is fixedly installed on the top of the workbench. A leveling shell is fixedly installed on the top of the inner side of the second U-shaped plate. A spring is fixedly installed on the inner side of the leveling shell. A leveling plate is slidably connected to the inner side of the leveling shell. The end of the spring away from the leveling shell is fixedly connected to the leveling plate.

[0007] More preferably, the inner side of the housing is movably connected to a bidirectional threaded rod via a rotating shaft, and clamping plates are threadedly connected to both functional sides of the surface of the bidirectional threaded rod. A second motor is fixedly installed on both functional sides of the inner side of the housing, and the clamping plates are slidably connected to the surface of the second motor.

[0008] More preferably, a replacement plate is provided on the inner side of the clamping plate, and a snap-fit ​​groove is provided on the left and right sides of the top of the replacement plate. A snap-fit ​​post is fixedly installed on the front and rear sides of the inner side of the clamping plate, and the snap-fit ​​post is snapped into the inner side of the snap-fit ​​groove. A cutter head is fixedly installed on the bottom of the replacement plate.

[0009] More preferably, a second motor is fixedly installed on the left side of the housing, and the output end of the second motor is fixedly connected to a bidirectional threaded rod.

[0010] More preferably, both the left and right sides of the inner side of the workbench are movably connected to conveyor rollers via rotating shafts, and the surfaces of the conveyor rollers are connected to conveyor belts.

[0011] More preferably, a first motor is fixedly installed on the rear side of the worktable, and the output end of the first motor is fixedly connected to the conveyor roller.

[0014] The present invention has the following advantages due to the adoption of the above technical solution: I. This utility model uses the surface threads of the bidirectional threaded rod to drive the clamping plate to move outward. As the clamping plate moves outward, the locking pin moves out of the inner side of the locking groove, releasing the restriction on the replacement plate and the cutter head, which facilitates the quick replacement of the cutter head by the operator and reduces downtime.

[0015] II. This utility model uses the pressure of the leather on the surface of the conveyor belt to drive the flat plate upward. As the flat plate moves upward, it squeezes the spring. The spring deforms under the pressure, which applies pressure to the flat plate and the flat roller, thus flattening the leather on the surface of the flat plate and avoiding the decline in cutting quality due to uneven leather surface.

[0020] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0021] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] Example 1 like Figure 1-6 As shown, this utility model embodiment provides a cutting device for leather processing, including: The cutting assembly 100 includes a workbench 101. A first U-shaped plate 106 is fixedly installed on the top left side of the workbench 101. A cylinder 107 is fixedly installed on the top of the first U-shaped plate 106. An installation plate 108 is fixedly connected to the output end of the cylinder 107. A housing 109 is provided at the bottom of the installation plate 108. The top of the installation plate 108 is threadedly connected to the housing 109 by a plurality of fastening screws. A leveling assembly 200 includes a second U-shaped plate 201, which is fixedly installed on the top of the workbench 101. A leveling shell 202 is fixedly installed on the top inner side of the second U-shaped plate 201. A spring 203 is fixedly installed on the inner side of the leveling shell 202. A leveling plate 204 is slidably connected to the inner side of the leveling shell 202. The end of the spring 203 away from the leveling shell 202 is fixedly connected to the leveling plate 204. A bidirectional threaded rod 110 is movably connected to the inner side of the outer shell 109 via a rotating shaft. Clamping plates 112 are threadedly connected to both sides of the surface of the bidirectional threaded rod 110. A second motor 116 is fixedly installed on both sides of the inner side of the outer shell 109. The clamping plates 112 are slidably connected to the surface of the second motor 116.

[0023] The clamping plate 112 moves outward due to the thread on the surface of the bidirectional threaded rod 110. As the clamping plate 112 moves outward, the locking post 113 moves out of the inner side of the locking groove 114, releasing the restriction on the replacement plate 111 and the cutter head 115. This facilitates the quick replacement of the cutter head 115 by the staff and reduces downtime.

[0024] Example 2 like Figure 1-6 As shown, in one embodiment, a replacement plate 111 is provided on the inner side of the clamping plate 112. The top left and right sides of the replacement plate 111 are provided with snap-fit ​​grooves 114. Snap-fit ​​posts 113 are fixedly installed on the front and rear sides of the inner side of the clamping plate 112, and the snap-fit ​​posts 113 snap into the inner side of the snap-fit ​​grooves 114. A cutter head 115 is fixedly installed at the bottom of the replacement plate 111. A second motor 116 is fixedly installed on the left side of the outer casing 109. The output end of the second motor 116 is fixedly connected to a bidirectional threaded rod 110. Conveyor rollers 103 are movably connected to the left and right sides of the inner side of the worktable 101 via rotating shafts. A conveyor belt 104 is connected to the surface of the conveyor roller 103. A first motor 105 is fixedly installed on the rear side of the worktable 101. The output end of the first motor 105 is fixedly connected to the conveyor roller 103. A support column 102 is fixedly installed at the bottom of the worktable 101. There are four support columns 102, which are equidistantly distributed at the bottom of the worktable 101. A leveling roller 205 is movably connected to the inner side of the leveling plate 204 through a rotating shaft. Limiting rods 206 are fixedly installed on the front and rear sides of the top of the leveling plate 204. The limiting rods 206 penetrate the second U-shaped plate 201 and extend to the top of the second U-shaped plate 201.

[0025] The leveling roller 205 is driven by the pressure of the leather on the surface of the conveyor belt 104 to move the leveling plate 204 upward. As the leveling plate 204 moves upward, it squeezes the spring 203. The spring 203 is squeezed and deformed, which puts pressure on the leveling plate 204 and the leveling roller 205, and flattens the leather on the surface of the leveling plate 204 to avoid uneven leather surface from causing a decrease in cutting quality.

[0026] In operation, this invention works as follows: First, the leather to be cut is placed on top of the conveyor belt 104. The first motor 105 is then started, and its output drives the conveyor roller 103 to rotate. Simultaneously, the conveyor roller 103 rotates, causing the conveyor belt 104 to rotate as well, thus conveying the leather. During this conveying process, the leveling roller 205, under the pressure of the leather on the surface of the conveyor belt 104, moves the flat plate 204 upwards. As the flat plate 204 moves upwards, it compresses the spring 203. The spring 203 deforms under this pressure, applying pressure to the flat plate 204 and the leveling roller 205, thus smoothing the leather on the surface of the flat plate 204. To avoid uneven leather surfaces that could reduce cutting quality, when the leather reaches the bottom of the cutter head 115, the cylinder 107 is activated. The cylinder 107 drives the mounting plate 108, housing 109, replacement plate 111, and cutter head 115 to descend, cutting the leather. When the cutter head 115 needs to be replaced, the threads on the surface of the bidirectional threaded rod 110 drive the clamping plate 112 to move outward. Finally, as the clamping plate 112 moves outward, the locking post 113 moves out of the inside of the locking groove 114, releasing the restriction on the replacement plate 111 and cutter head 115. This facilitates quick replacement of the cutter head 115 by the operator and reduces downtime.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
