Description

Technical Field

[0001] The utility model relates to the technical field of soft leather processing, in particular to an environmentally friendly water squeezing device for processing chrome-free tanned soft leather. Background Art

[0002] In the process of processing soft leather, since a lot of free water is retained in the soft leather, it is necessary to remove the free water in the subsequent soft leather processing. However, exposing it to the sun or baking it at high temperature will seriously damage the quality of the soft leather. Therefore, it is necessary to squeeze out the water through a water squeezing device.

[0003] The patent document with application number CN202121893912.8 discloses a water squeezing device for processing wax-changed, flex-resistant, chrome-free tanned soft leather, comprising a first transmission mechanism, a second transmission mechanism and a water squeezing mechanism, the water squeezing mechanism comprising a first pressure roller and a second pressure roller, the first pressure roller being connected directly above the second pressure roller, the water squeezing mechanism also comprising a screw hole, a mounting seat and a bolt, the bolt being threadedly connected in the mounting seat and the screw hole. The utility model solves the problem that the existing water squeezing device can usually only squeeze water for soft leather of fixed thickness, cannot squeeze water for multiple layers of soft leather at one time, or adjust the size of the water squeezing mechanism to squeeze water according to soft leathers of different thicknesses, and the water squeezing component in the existing water squeezing device is inconvenient to disassemble and replace during use by arranging a water squeezing mechanism. The utility model has the advantages of being convenient for squeezing water for soft leathers of different sizes and being convenient for disassembling and assembling the first pressure roller and the second pressure roller.

[0004] The above application adopts the method of screwing the bolts at both ends of the second pressure roller and tightening the mounting seats at both ends into the screw holes at different positions on the inner side of the support plate to make the device suitable for soft leathers of various thicknesses. However, since the positions of the screw holes are fixed, the adjustable range is limited, thereby reducing the applicability of the device. In addition, when squeezing water from the soft leather, part of the water squeezed out by the device will remain on the surface of the soft leather, thereby increasing the drying time required for the soft leather and reducing the processing efficiency. In response to the above problems, we have introduced an environmentally friendly squeezing device for chrome-free tanned soft leather processing. Utility Model Content

The water in the sump can be discharged through the drain pipe by opening the valve.

[0009] In a preferred solution, the clamping assembly includes two receiving grooves opened on the inner wall of the top end of the upper mounting seat, the inner wall of the receiving groove is fixedly connected with a slide rod, the surface of the slide rod is sleeved with a clamping spring, the bottom end of the upper mounting seat is movably connected with a lower mounting seat, the upper mounting seat and the lower mounting seat are fixed by bolts, the front and rear ends of the conveyor belt are fixedly connected with an electric push rod, and the telescopic end of the electric push rod is fixedly connected with a limiting plate.

[0010] By arranging the clamping assembly, the second squeezing roller can always be in close contact with the first squeezing roller, so that the water absorbed by the absorbent sponge can be squeezed out, which effectively enhances the water absorption capacity of the absorbent sponge. By screwing the bolts, the lower mounting seat can be separated from the upper mounting seat, so as to facilitate the disassembly and replacement of the first squeezing roller. By arranging the electric push rod and the limit plate, the soft leather can be limited, so as to prevent the soft leather from deviating during the squeezing process and affecting the squeezing effect.

DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] The utility model discloses an environment-friendly water squeezing device for chrome-free tanned soft leather processing, which is mainly used in scenarios where the adjustable range is limited and part of the water squeezed out by the device will remain on the surface of the soft leather when squeezing the soft leather.

[0019] Reference Figure 1 , Figure 2 and Figure 3 , an environmentally friendly water squeezing device for processing chrome-free tanned soft leather, comprising a base 1, a water collecting trough 2 is arranged below the base 1, a drain pipe 3 is arranged at the front end of the water collecting trough 2, a valve is arranged on the surface of the drain pipe 3, a conveyor belt 4 is fixedly connected to the top of the base 1, and a plurality of water holes 5 are opened on the surface of the conveyor belt 4, and also comprises: a water squeezing component: the water squeezing component comprises a support frame 6 arranged above the base 1, a cylinder 7 is fixedly connected to the top of the support frame 6, an upper mounting seat 8 is fixedly connected to the telescopic end of the cylinder 7, a first squeezing roller 9 is movably connected in the upper mounting seat 8, a water-absorbing sponge 10 is sleeved on the surface of the first squeezing roller 9, a second squeezing roller 11 is arranged on the left side of the first squeezing roller 9 at the top of the upper mounting seat 8, a water receiving box 12 is fixedly connected to the front and rear ends of the second squeezing roller 11 at the top of the upper mounting seat 8, and the water receiving box 12 is connected to the water collecting trough 2 through a pipeline; a clamping component: the clamping component is arranged between the first squeezing roller 9 and the second squeezing roller 11.

[0020] In this solution, by setting up a water squeezing component and a conveyor belt 4, not only can the water of soft leathers of different thicknesses be squeezed, but also the residual water on the surface of the soft leather can be absorbed, thereby reducing the residual moisture in the soft leather, effectively reducing the time required for the soft leather to be dried, and improving the processing efficiency. The water in the sump 2 can be discharged through the drain pipe 3 by opening the valve.

[0021] Among them, a tensioning wheel 19 is arranged at the bottom end of the conveyor belt 4, the bottom surface of the water receiving box 12 is higher than the bottom surface of the first squeezing roller 9, the size of the water collecting trough 2 is greater than or equal to the size of the conveyor belt 4, and the size of the water receiving box 12 is greater than or equal to the size of the second squeezing roller 11; by setting the tensioning wheel 19, the transmission tightness of the conveyor belt 4 is guaranteed, the bottom surface of the water receiving box 12 is higher than the bottom surface of the first squeezing roller 9 to prevent the first squeezing roller 9 from being unable to continue to move downward due to the water receiving box 12 contacting the soft leather before the first squeezing roller 9, the size of the water collecting trough 2 is greater than the size of the conveyor belt 4 and the size of the water receiving box 12 is greater than the size of the second squeezing roller 11, which ensures that the squeezed water will not fall outside the device.

[0022] Reference Figure 1 and Figure 2 In a preferred embodiment, the clamping assembly includes two receiving grooves 13 opened on the inner wall of the top end of the upper mounting seat 8, the inner wall of the receiving groove 13 is fixedly connected with a slide rod 14, the surface of the slide rod 14 is sleeved with a clamping spring 15, the bottom end of the upper mounting seat 8 is movably connected with a lower mounting seat 16, the upper mounting seat 8 and the lower mounting seat 16 are fixed by bolts, the front and rear ends of the conveyor belt 4 are fixedly connected with an electric push rod 17, and the telescopic end of the electric push rod 17 is fixedly connected with a limiting plate 18.

[0023] Specifically, the second squeezing roller 11 can be pushed to slide on the surface of the slide rod 14 in the containing groove 13 by the compression spring 15, so that the second squeezing roller 11 can be close to the first squeezing roller 9, thereby squeezing out the water absorbed by the water-absorbing sponge 10 sleeved on the surface of the first squeezing roller 9, and effectively enhancing the water absorption capacity of the water-absorbing sponge 10. The lower mounting seat 16 can be separated from the upper mounting seat 8 by tightening the bolts, thereby facilitating the disassembly and replacement of the first squeezing roller 9. In the process of squeezing water from the soft leather, the electric push rod 17 will push the limiting plate 18 to move toward the soft leather, thereby limiting the soft leather and preventing the soft leather from deviating during the squeezing process and affecting the squeezing effect.

[0024] Working principle: When in use, the cylinder 7 at the top of the support frame 6 will push the upper mounting seat 8 toward the soft leather until the first squeezing roller 9 is close to the soft leather. The conveyor belt 4 can be used to adjust the distance between the first squeezing roller 9 and the soft leather according to the thickness of the soft leather to squeeze out the water in the soft leather. The squeezed water will fall into the water collecting tank 2 through the water holes 5 on the surface of the conveyor belt 4. While squeezing the water from the soft leather, the first squeezing roller 9 can absorb the residual water on the surface of the soft leather through the absorbent sponge 10 on its surface. The squeezed water will fall into the water receiving box 12 and finally fall into the water collecting tank 2 through the pipeline, thereby reducing the residual water in the soft leather, effectively reducing the time required for the soft leather to be dried, and improving the processing efficiency. The water in the water collecting tank 2 can be discharged through the drain pipe 3 by opening the valve.

[0025] The above are only preferred specific implementations of the utility model, but the protection scope of the utility model is not limited to them. The replacement can be a replacement of part of the structure, device, method steps, or a complete technical solution. Equivalent replacement or changes based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
