Description

Technical Field

[0001] This utility model relates to the field of leather-shaped product processing technology, and in particular to a grooving device for processing high-density leather-shaped products. Background Technology

[0002] Grooving is a crucial piece of equipment in wet fur processing, used to perform steps such as soaking, degreasing, softening, pickling, and tanning of fur at specific temperatures. However, traditional processing equipment currently on the market suffers from several problems that affect production: Because the leather absorbs a large amount of reaction liquid during processing, during the process of replacing the reaction liquid in the trough, the reaction liquid continuously seeps out of the leather and is difficult to remove quickly. In order to ensure the effect of liquid replacement and reduce the amount of waste liquid remaining in the trough, the operators need to drain it multiple times, which increases the workload.

[0003] Therefore, those skilled in the art urgently need to develop a grooving device for processing high-density leather-shaped products. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grooving device for processing high-density leather-shaped products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a grooving device for processing high-density leather-shaped products, comprising a base, two side-by-side support frames on the base, a groove between the two support frames, both ends of the groove being rotatably connected to the support frames via groove shafts, a filter cylinder inside the groove, a scraping assembly in the middle of the filter cylinder, scraping shafts at both ends of the scraping assembly being connected to scraping shafts, and the two scraping shafts passing through the filter cylinder and rotatably connected to the groove, the filter cylinder being rotatably connected to the scraping shafts at both ends, a drive motor connected to the scraping shaft at the right end being provided on the right side of the groove; an angle adjustment assembly for controlling the rotation of the groove being provided on the side of the support frame, and locking assemblies for controlling the filter cylinder being provided on the two side plates of the groove.

[0006] Preferably, the tank and the filter cartridge each consist of two side plates and a bottom plate, and the bottom plate of both the tank and the filter cartridge has an arc-shaped structure.

[0007] Preferably, the angle adjustment assembly includes a support platform connected to the base, a telescopic cylinder hinged to the support platform, and the output end of the telescopic cylinder connected to the tank.

[0008] Preferably, the locking assembly includes a control box that is connected to two side plates of the tank respectively. The control box is provided with a transverse limiting rod inside. A fixing groove is provided on both side plates of the filter cartridge. One end of the limiting rod passes through the tank and extends into the fixing groove.

[0009] Preferably, a slider is provided on the side of the limiting rod away from the fixed groove, the contact surfaces of the limiting rod and the slider are both inclined surfaces, a retaining ring is sleeved on the limiting rod, a spring is sleeved on the left side of the retaining ring and sleeved on the limiting rod, the bottom of the slider is connected to the driving block, a limiting plate is slidably connected to the left side of the driving block, the limiting plate is connected to the control box, a rack is connected to the right side of the driving block, a gear is meshed on the edge of the rack, and a servo motor connected to the gear is provided inside the control box.

[0010] Preferably, the peeling assembly includes two fixed discs placed side by side, and a plurality of scribing plates located between the two fixed discs. The scribing plates are close together on the side near the center of the fixed discs and are distributed in a radiating pattern on the side away from the center, and the spacing between the scribing plates is consistent.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This grooving device achieves rapid fixing and unlocking of the filter cartridge through an automated locking structure, eliminating the need for manual operation of fastening components and significantly reducing downtime for material changes. At the same time, with the cooperation of multiple sets of circumferential fixing grooves and limit rods, it ensures that the filter cartridge is stable and does not shake during processing, effectively avoiding grooving accuracy problems caused by filter cartridge misalignment.

[0012] During the liquid change operation, the device utilizes the relative rotation design between the filter cartridge and the tank. During liquid change, the leather-shaped products can remain inside the filter cartridge without manual transfer. This reduces the damage and loss of the leather during the transfer process and avoids the pollution of the workshop environment by the dripping waste liquid. At the same time, the filter pore structure of the filter cartridge can intercept the debris generated during processing and prevent the debris from clogging the pipeline with the waste liquid discharge.

[0013] The equipment integrates functions such as locking, mixing, and liquid changing into one unit. The entire process is automated through motors and cylinders, which greatly reduces the number of steps required for operator intervention and reduces labor intensity. At the same time, the inclined tank design reduces the amount of waste liquid residue in the equipment, reducing the workload of subsequent cleaning and maintenance. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] Please see Figures 1-4 This utility model provides an embodiment: a grooving device for processing high-density leather-shaped products, including a base 1, two side-by-side support frames 2 on the base 1, a groove 3 between the two support frames 2, the two ends of the groove 3 being rotatably connected to the support frames 2 through a groove shaft 31, the axial direction of the groove shaft 31 being perpendicular to the height direction of the support frames 2, and the groove 3 being able to rotate around the groove shaft 31 in a vertical plane.

[0020] The tank 3 is equipped with a filter cylinder 4. Both the tank 3 and the filter cylinder 4 are composed of two side plates and a bottom plate. The radius of the arc-shaped bottom plate of the tank 3 is larger than that of the arc-shaped bottom plate of the filter cylinder 4. Both the bottom plates of the tank 3 and the filter cylinder 4 are arc-shaped. The arc-shaped bottom plate of the filter cylinder 4 is evenly provided with several filter holes for filtering waste liquid or debris generated during the processing.

[0021] A scraping assembly 5 is provided in the middle of the filter cylinder 4. The scraping assembly 5 includes two fixed disks placed side by side and multiple scribing plates located between the two fixed disks. The scribing plates are close together on the side near the center of the fixed disks and are distributed in a divergent manner on the side away from the center, and the spacing between the scribing plates is consistent (equal included angles). Scraping shafts 51 are connected to both ends of the scraping assembly 5, and the two scraping shafts 51 pass through the filter cylinder 4 and are rotatably connected to the tank body 3. The filter cylinder 4 is rotatably connected to the scraping shafts 51 at both ends through bearings. A drive motor 6 is provided on the right side of the tank body 3 and is connected to the scraping shaft 51 at the right end. The output shaft of the drive motor 6 is connected to the scraping shaft 51 at the right end through a coupling, which can drive the scraping assembly 5 to rotate.

[0022] The support frame 2 is provided with an angle adjustment component for controlling the rotation of the tank 3. The two side plates of the tank 3 are provided with locking components for controlling the filter cartridge 4. The angle adjustment component includes a support platform 7 connected to the base 1. A telescopic cylinder 8 is hinged on the support platform 7. The output end of the telescopic cylinder 8 is connected to the tank 3.

[0023] The rotation of the tank body 3 is controlled by the telescopic cylinder 8. Since the leather-shaped product is placed inside the filter cylinder 4, the filter cylinder 4 remains unchanged due to gravity. While the tank body 3 rotates, the internal liquid is poured out and the liquid is replaced. At the same time, the leather-shaped product inside the tank body 3 remains unchanged inside the filter cylinder 4.

[0024] Furthermore, the locking assembly includes a control box 9 connected to two side plates of the tank 3 respectively. The control box 9 is provided with a transverse limiting rod 10 inside. The filter cartridge 4 is provided with a fixing groove 41 on both side plates. One end of the limiting rod 10 passes through the tank 3 and extends into the fixing groove 41 to achieve the positioning of the filter cartridge 4.

[0025] A slider 13 is provided on the side of the limiting rod 10 away from the fixing groove 41. The contact surfaces of the limiting rod 10 and the slider 13 are both inclined planes at 45°. When the slider 13 moves upward, it pushes the limiting rod 10 towards the side closer to the fixing groove 41 through the inclined plane. A retaining ring 12 is sleeved on the limiting rod 10. A spring 11 is sleeved on the left side of the retaining ring 12 and is sleeved on the limiting rod 10. When the limiting rod 10 is inside the fixing groove 41, the spring 11 is compressed. When the slider 13 moves downward, the spring 11 restores its deformation and drives the limiting rod 10 to be removed from inside the fixing groove 41, thereby canceling the fixation and unlocking the filter cartridge 4.

[0026] The bottom of slider 13 is connected to drive block 14. A limit plate 15 is slidably connected to the left side of drive block 14, and limit plate 15 is connected to control box 9. A rack 16 is connected to the right side of drive block 14, and a gear 17 meshes with the edge of rack 16. A servo motor connected to gear 17 is installed inside control box 9. The servo motor drives the rotation of gear 17, which in turn drives the rack 16 to move up and down, thereby controlling the up and down movement of slider 13.

[0027] Working principle of this utility model: 1. Preparation stage: The control motor (servo motor) of the locking assembly is started, driving the gear 17 to rotate, which drives the rack 16 and the drive block 14 to rise. The slider 13 rises with the drive block 14 and pushes the limit rod 10 through the inclined plane to compress the spring 11, so that the limit rod 10 is inserted into the corresponding fixed groove 41, thereby locking the filter cartridge 4. Then, the leather-shaped product and reaction liquid are added to the tank 3.

[0028] II. Processing stage: Start the drive motor 6, and its output shaft drives the scraping shaft 51 to rotate through the coupling. The scraping assembly 5 rotates synchronously with the shaft; then the leather product is turned over to make it fully and evenly mixed with the treatment liquid for processing.

[0029] III. Liquid Replacement Stage: When the reaction liquid needs to be replaced, the servo motor controlling the locking component reverses, the slider 13 moves down, the spring 11 recovers its deformation and drives the limit rod 10 to be removed from the inside of the fixed groove 41, thereby unlocking the filter cartridge 4. The rotation of the tank body 3 is controlled by the telescopic cylinder 8. Since the leather-shaped product is placed inside the filter cartridge 4, the filter cartridge 4 remains unchanged due to gravity. While the tank body 3 rotates, the internal liquid is poured out and the liquid is replaced. At the same time, the leather-shaped product inside the tank body 3 remains unchanged inside the filter cartridge 4. After that, the locking and liquid addition are performed.

[0030] IV. End Stage: After processing is completed, turn off the drive motor 6, control the locking assembly to unlock the filter cylinder 4, the telescopic cylinder 8 drives the tank 3 to rotate to pour out the liquid and then reset, lock the filter cylinder 4 again, the telescopic cylinder 8 drives the tank 3 to rotate to pour out the leather-shaped product, and complete one processing cycle.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
