Description

Technical Field

[0001] This utility model relates to the technical field of bag and luggage leather processing equipment, specifically to a chrome-free bag and luggage leather processing equipment. Background Technology

[0002] Chromium-free leather is a type of leather used for tanning without chromium salts. It has advantages such as being environmentally friendly and safe. During the processing of chromium-free leather, it needs to be soaked in water to restore the moisture of the dried raw hide and soften the fiber structure.

[0003] The existing soaking methods mostly involve manually placing stacked raw hides in a water tank, which causes multiple raw hides to stick together, resulting in insufficient soaking and thus reducing the soaking efficiency of the raw hides. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a processing device for chromium-free bag leather.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a processing equipment for chrome-free bag leather, including a water tank, a drain pipe at the bottom of the water tank, a valve on the drain pipe, and multiple support plates inside the water tank, which are connected by support rods, with the support rods located at the four corners inside the water tank.

[0006] The support plate is provided with multiple cavities;

[0007] Two limiting frames are symmetrically arranged on the top of the water tank. The outer end of the limiting frame has an opening, and positioning frames are provided on both sides of the opening. A transmission gear is provided between the two positioning frames. A rotating shaft is fixedly installed in the middle part of the transmission gear, passing through the positioning frame and rotatably connected to the positioning frame. Two side plates are symmetrically arranged on both sides of the top support plate, passing through the limiting frame. The outer side of the side plate has a toothed plate that passes through the opening, and the transmission gear meshes with the toothed plate. A box body is provided on the rear side of the water tank. A second driven bevel gear is provided at the end of the rotating shaft away from the transmission gear, located inside the box body, and the rotating shaft is rotatably connected to the box body. A drive shaft is rotatably arranged laterally inside the box body. A first driven bevel gear is provided in the middle part of the drive shaft, and second drive bevel gears that mesh with the second driven bevel gear are provided at both ends of the drive shaft. A motor is provided in the middle part of the box body, and a first drive bevel gear that meshes with the first driven bevel gear is provided at the output end of the motor.

[0008] First, start the motor to make the two transmission gears rotate synchronously in opposite directions, causing the two side plates to rise inside the water tank along with the support plates. Through the action of multiple support rods, multiple support plates can rise synchronously. Then, lay the raw hides to be soaked on the support plates. After laying, start the motor again to lower multiple support plates into the water tank, which will prevent the raw hides from piling up and sticking together inside the water tank.

[0009] To improve the stability of the bearing plate during use, the present invention is improved by fixing the support rods at the four corners of the multiple bearing plates respectively.

[0010] To improve the water immersion efficiency of bag leather, the present invention includes an improvement where the supporting plate is provided with multiple raised strips.

[0011] To improve the stability of the housing during use, the present invention includes an improvement in that the housing is provided with a limiting frame through which the drive shaft passes, and the drive shaft is rotatably connected to the limiting frame.

[0012] Furthermore, an improvement of this utility model is that the bearing plate, support rod, and side plate are all made of metal.

[0013] Furthermore, an improvement of this utility model is that the motor is a servo motor.

[0014] Compared with the prior art, this utility model provides a processing equipment for chrome-free bag leather, which has the following beneficial effects:

[0015] This processing equipment, through its innovative structural design, effectively solves the problem of insufficient soaking caused by the stacking of raw hides in traditional soaking methods. Multiple support plates are connected by support rods to form a three-dimensional support structure. Combined with the transmission system of transmission gears and toothed plates, it realizes the layered placement and automatic lifting of raw hides, so that each raw hide can fully contact the water and greatly improve the soaking efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 The present invention relates to a processing equipment for chrome-free bag leather, comprising a water tank 1, a drain pipe 2 at the bottom of the water tank 1, a valve on the drain pipe 2, and multiple support plates 3 inside the water tank 1, which are connected by support rods 4, and the support rods 4 are respectively located at the four corners inside the water tank 1.

[0023] The support plate 3 is provided with multiple cavities 6;

[0024] Two limiting frames 8 are symmetrically arranged on the top of the water tank 1. Each limiting frame 8 has an opening at its outer end, and positioning frames 9 are located on both sides of the opening. A transmission gear 10 is located between the two positioning frames 9. A rotating shaft 11 is fixedly installed in the middle of the transmission gear 10, passing through and rotatably connected to the positioning frames 9. Two side plates passing through the limiting frames 8 are symmetrically arranged on both sides of the top support plate 3. Toothed plates 7 with through openings are located on the outer sides of the side plates, and the transmission gear 10 meshes with the toothed plates 7. A tank body 12 is located at the rear of the water tank 1. The rotating shaft... A second driven bevel gear 18 is provided at one end away from the transmission gear 10 and located inside the housing 12. The shaft 11 is rotatably connected to the housing 12. A drive shaft 14 is rotatably arranged inside the housing 12. A first driven bevel gear 15 is provided in the middle part of the drive shaft 14. A second drive bevel gear 17 that meshes with the second driven bevel gear 18 is provided at both ends of the drive shaft 14. A motor 13 is provided in the middle part of the housing 12. A first drive bevel gear 16 that meshes with the first driven bevel gear 15 is provided at the output end of the motor 13.

[0025] The support rods 4 are fixed at the four corners of the multiple bearing plates 3 respectively.

[0026] The housing 12 has a limiting frame 8 inside which is penetrated by the drive shaft 14, and the drive shaft 14 is rotatably connected to the limiting frame 8.

[0027] The core of the operation of this chrome-free leather processing equipment lies in the coordinated design of the power transmission and load-bearing structure.

[0028] When the motor 13 is started, the first drive bevel gear 16 at the output end of the motor 13 begins to rotate, driving the first driven bevel gear 15 through meshing, which in turn causes the drive shaft 14 to rotate. The second drive bevel gears 17 at both ends of the drive shaft 14 then rotate synchronously, meshing with the second driven bevel gear 18 and transmitting power to the rotating shaft 11, causing the transmission gear 10 to start rotating.

[0029] Since the transmission gear 10 meshes with the toothed plate 7, the rotation of the transmission gear 10 causes the side plate to move up and down within the opening of the limiting frame 8. The side plate is connected to the top bearing plate 3. Through the connection of the support rod 4, multiple bearing plates 3 can be raised and lowered synchronously.

[0030] When it is necessary to soak the raw hides, first start motor 13 to raise the support plate 3, and lay the raw hides flat on the support plate 3. Then start motor 13 again to lower the support plate 3 into the water tank 1. At this time, the raw hides are evenly distributed on different support plates 3, avoiding stacking and sticking together. The raised strips 5 on the support plate 3 increase the contact area with the leather, and the cavity structure 6 facilitates water circulation, ensuring that the raw hides are fully soaked in the water tank 1.

[0031] The support plate 3 is provided with multiple protrusions 5.

[0032] The raised strips 5 on the support plate 3 further increase the contact area between the leather and the water flow, enhancing the water immersion effect.

[0033] The bearing plate 3, support rod 4, and side plate are all made of metal.

[0034] The equipment uses metal bearing plates 3, support rods 4 and side plates to ensure the stability and durability of the structure. The bearing plates 3, support rods 4 and side plates are all made of stainless steel. The limit frame 8 inside the housing 12 improves the stability of the drive shaft 14 when it rotates, ensuring the smooth operation of the entire transmission system.

[0035] The motor 13 is a servo motor.

[0036] The use of servo motors enables precise control of the lifting process of the support plate 3, making operation convenient and reliable. This equipment replaces manual operation with mechanical transmission, not only reducing labor input but also ensuring the uniformity and consistency of raw hide soaking, laying a solid foundation for subsequent processing of chrome-free leather bags, and possessing significant practical and environmental value.
