Description

Technical Field

[0001] The present application relates to the technical field of leather production, and in particular to a leather stretching and smoothing device. Background Art

[0002] Leather stretching is to stretch the leather to the maximum fur size after heating, making the leather more stretched and larger in size. The existing processing method is to place the leather on a perforated board for flattening and air-drying.

[0003] Although the perforated board is convenient for leveling, one side of the fur after leveling is in contact with the perforated board, which reduces the drying area and prolongs the drying time. In view of the above-mentioned related technologies, the applicant believes that reducing the contact area between the leveling device and the fur after the fur leveling work is completed can speed up the drying efficiency and improve the quality of fur production. Utility Model Content

[0007] By adopting the above technical solution, the flattening structure has a large plane, but the large contact area also leads to a slow air-drying process. However, the device separately sets a movable bracket and a flattening structure, so that the flattening structure can be moved laterally to separate from the fur surface, thereby achieving a rapid air-drying effect. The positioning structure provided on the flattening mechanism retains the original flavor of the part containing the clamping structure under the action of the separation structure, so that the fur can achieve a very good air-drying effect while maintaining its flat state.

[0009] By adopting this technical solution, the combination of a drive motor and a drive screw enables precise position control of the leveling plate. Users can adjust the speed of the drive motor to control the forward and backward sliding distance of the leveling plate. This automated adjustment greatly improves the accuracy and efficiency of the operation and is particularly suitable for applications that require frequent position adjustments.

[0010] Preferably, the positioning structure includes a positioning sleeve and a return spring, the positioning sleeve extends transversely perpendicular to the flat plate and slides through the side wall of the flat plate; one end of the return spring is fixed to the flat plate, and the other end is fixed and drives the positioning sleeve to move toward the rear end of the flat plate.

[0011] By adopting the above technical solution, the application of the return spring enables the positioning sleeve to automatically return to the preset position after the external force is released. This not only simplifies the operation process but also improves work efficiency.

[0013] By adopting the above technical solution, the installation sleeve is accommodated in the positioning sleeve, which not only saves space but also enhances the stability of the entire clamping mechanism and improves the stability and accuracy during operation.

[0014] Preferably, the mounting assembly includes a disassembly connecting rod and a clamping block, the disassembly connecting rod is fixed to the outer wall of the mounting sleeve and extends toward the side away from the clamping seat, the disassembly connecting rod is passed through the inner wall of the positioning sleeve and extends outward, the disassembly connecting rod is elastic and can approach each other; the clamping block is fixed to the side wall of the disassembly connecting rod close to the positioning sleeve, and the clamping block abuts against the end face of the positioning sleeve at one end relative to the clamping seat.

[0025] The present application is further described in detail below with reference to the accompanying drawings.

[0026] The present application discloses a leather stretching and smoothing device, referring to Figure 1 、 2 , including a mobile bracket 1 for easy movement and placement, the inside of the mobile bracket 1 accommodates a leveling structure 2 that extends vertically and is used to flatten the fur; the leveling structure 2 includes a leveling plate 21, a driving motor 22 and a driving screw 23, the leveling plate 21 extends vertically and is horizontally slidably connected to the mobile bracket 1, and a positioning structure 3 for positioning the fur is provided on the leveling plate 21.

[0027] Reference Figure 3 、 4The positioning structure 3 includes a positioning sleeve 31 and a return spring 32. The positioning sleeve 31 extends horizontally and perpendicularly to the flat plate 21 and slides through the side wall of the flat plate 21. One end of the return spring 32 is fixed to the flat plate 21, and the other end is fixed and drives the positioning sleeve 31 to move toward the rear end of the flat plate 21, so that the front plane of the flat plate 21 remains flat.

[0028] Reference Figure 3 、 4 The positioning sleeve 31 clamps the fur through the clamping structure 5. The clamping structure 5 includes a mounting sleeve 51, a clamping seat 52 and a clamping screw 53. The mounting sleeve 51 is accommodated on the side of the positioning sleeve 31 close to the front end of the flat plate 21; the clamping seat 52 accommodates and is rotatably connected to the mounting sleeve 51 and extends outward, thereby adapting to the various angles of support of the fur; the clamping screw 53 is screwed to the outward extending end of the clamping seat 52 and can abut against the rotating end of the clamping seat 52. The support seat and the clamping screw 53 cooperate to clamp the fur.

[0029] Reference Figure 3 、 4 The clamping seat 52 is positioned on the movable bracket 1 through the separation structure 6 and remains flush with the flat plate 21. The separation structure 6 includes a positioning rod 61 and a limiting rod 62. The positioning rod 61 is vertically spaced and penetrates the front surface of the flat structure 2 and remains flush with the flat plate 21, and the positioning rod 61 is fixed to the movable bracket 1; the limiting rod 62 is rotated along the plane of the flat structure 2 and is connected to one side of the clamping seat 52. The limiting rod 62 is staggered with the clamping screw 53 to prevent interference with the clamping of the fur. The limiting rod 62 abuts against the side wall of the positioning rod 61, so that the front end of the clamping seat 52 is positioned flush with the flat plate 21; at the same time, there is only one positioning rod 61 on the left and right sides of the clamping seat 52. By rotating the limiting rod 62 and cooperating with the positioning rod 61, the number of positioning rods 61 is reduced, thereby reducing the contact with the fur and accelerating the drying efficiency.

[0030] Reference Figure 3 、 5 The rear end of the clamping seat 52 is positioned at the corresponding mounting sleeve 51 through the mounting assembly 4. The mounting assembly 4 includes a disassembly connecting rod 41 and a clamping block 42. The disassembly connecting rod 41 is fixed to the outer wall of the mounting sleeve 51 and extends toward the side away from the clamping seat 52. The disassembly connecting rod 41 is passed through the inner wall of the positioning sleeve 31 and extends outward. The disassembly connecting rod 41 is elastic and can approach each other; the clamping block 42 is fixed to the side wall of the disassembly connecting rod 41 close to the positioning sleeve 31, and the clamping block 42 abuts against the end face of the positioning sleeve 31 relative to the clamping seat 52, so that the rear end of the mounting sleeve 51 is stably connected to the positioning sleeve 31; when it is necessary to disassemble and pinch the disassembly connecting rod 41, the clamping blocks 42 approach each other and are accommodated in the positioning sleeve 31 to realize the disassembly of the mounting sleeve 51.

[0031] Reference Figure 1 、2 The driving motor 22 is fixed to the rear end of the movable bracket 1; the driving screw 23 is fixed to the output shaft of the driving motor 22, and the driving screw 23 is screwed to the leveling plate 21; when the fur leveling work is completed, the leveling plate 21 is driven away from the fur by the driving motor 22, thereby accelerating the drying.

[0032] The actual working process of this application is: spread the fur flat on the front end of the leveling plate 21, then insert the installation sleeve 51 at various points on the leveling plate 21, and adjust the limit rod 62 to stagger the position of the fur and abut against the positioning rod 61. At this time, the clamping seat 52 is positioned by the front and rear ends of the clamping block 42 and the limit rod 62 to make the fur close to the leveling plate 21, so that the leveling work can be carried out smoothly.

[0033] When all the fur points are clamped and the fur is flat, the drive motor 22 is started. The drive motor 22 drives the flattening plate 21 to move backward away from the fur, so that there is sufficient drying space on the fur side. The positioning sleeve 31 without the installation sleeve 51 is supported by the reset spring 32 and moves backward with the flattening plate 21, while the positioning sleeve 31 with the installation sleeve 51 is inserted. Since the limit rod 62 abuts against the positioning rod 61, the positioning sleeve 31 and the flattening plate 21 slide relative to each other, the reset spring 32 is compressed, and the positions of the positioning sleeve 31 and the installation sleeve 51 remain unchanged, so that the fur continues to dry in a flat position.

[0034] When drying is completed, the driving motor 22 drives the flattening plate 21 to reset, pinch the disassembly connecting rods 41 on both sides and push them forward, install the sleeve 51 to quickly complete the disassembly, loosen the clamping screw 53, and the fur can be removed.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
