Description

Technical Field

[0001] This utility model relates to the field of leather processing, and in particular to an impregnation tank for reducing waste material. Background Technology

[0002] Impregnation is a common production process on leather production lines. The principle is to immerse the leather base fabric in an impregnation tank with an impregnation solution so that both sides of the base fabric can be evenly coated. Existing impregnation tanks, such as the impregnation tank in a wet leather production line as described in application 2018210301297, mainly include a tank body. One end of the tank body is equipped with an inlet wheel, and the other end is equipped with an outlet wheel. The tank body is equipped with several guide wheels, including an upper row of guide wheels above the liquid surface and a lower row of guide wheels below the liquid surface. A squeezing mechanism is provided above the upper row of guide wheels, and a scraping mechanism is provided between the last lower row of guide wheels and the outlet wheel. A bubbling device is provided at the bottom of the tank body. In application, the leather base fabric is transported into the impregnation tank by the inlet wheel. Under the action of the guide wheels, after being fully impregnated by the lower row of guide wheels below the liquid surface, the leather base fabric is squeezed out by the upper row of guide wheels above the liquid surface and the squeezing mechanism, and then enters the liquid surface again. This process is repeated to make the coating more uniform. Then, the scraping mechanism scrapes the excess coating on the base fabric back into the impregnation tank, reducing coating loss. Finally, the base fabric is transported to the next process by the outlet wheel.

[0003] However, during the processing of the aforementioned impregnation tank, the leather base fabric passes along the outer edge of the guide rollers within the tank, forming an arc-shaped space that gradually expands from bottom to top between the guide rollers and the upper row of guide rollers. Since the hollow cavity of the tank is rectangular, it is much larger than the arc-shaped space. This requires a large amount of impregnation liquid to be placed in the tank, and since the impregnation liquid cannot be recycled, a large amount of residual impregnation liquid is wasted outside the arc-shaped space. Furthermore, excessive residual impregnation liquid makes it difficult to clean the tank later, increasing the workload.

[0004] In view of this, the inventors of this case conducted in-depth research on the problem, which led to the creation of this case. Utility Model Content

[0005] The purpose of this invention is to provide an impregnation tank that reduces residual material, thereby solving the problem of excessive residual impregnation liquid in existing impregnation tanks, which leads to waste.

[0006] To achieve its purpose, this utility model adopts the following technical solution:

[0007] An impregnation tank for reducing residual material includes a tank body, which is a hollow shell with an open top. The hollow cavity of the tank body is an impregnation chamber for placing the impregnation liquid. An inlet wheel is provided on one side of the top surface of the tank body, and an outlet wheel is provided on the other side. Guide wheels are provided inside the impregnation chamber, including an upper row of guide wheels above the surface of the impregnation liquid and a lower row of guide wheels below the surface of the impregnation liquid. A squeezing mechanism is provided above the upper row of guide wheels. With the side of the tank body with the inlet wheel designated as left and the side with the outlet wheel as right, a [missing information - likely a design feature] is provided inside the left side of the hollow cavity of the tank body. A partition plate divides the hollow chamber of the tank into two chambers. One chamber is a horn-shaped chamber that gradually expands from bottom to top. The horn-shaped chamber is a small-capacity soaking chamber. The other chamber has a lower chamber located below the horn-shaped chamber and a right chamber connected to the lower chamber and located to the right of the horn-shaped chamber. The lower chamber and the right chamber form a large-capacity soaking chamber. The inner bottom surface of the large-capacity soaking chamber is an inclined surface that slopes from left to right. The small-capacity soaking chamber and the large-capacity soaking chamber constitute the soaking chamber.

[0008] The lower guide wheel has a first lower guide wheel and a second lower guide wheel. The first lower guide wheel is rotatably installed in the small-capacity soaking chamber, and the second lower guide wheel is rotatably installed in the right chamber. The upper guide wheel is located to the right and above the second lower guide wheel. A transition wheel between the first lower guide wheel and the second lower guide wheel is rotatably installed on the top surface of the partition plate.

[0009] The tank is a hollow strip structure extending in the front-to-back direction. The partition plate has a bottom plate that is fixedly fitted with the left inner wall of the tank and an inclined plate that is connected to the right side of the bottom plate and tilts upward. The bottom plate is a strip-shaped plate structure extending in the front-to-back direction, and the bottom plate is laid flat and suspended above the bottom wall of the tank. The bottom plate, the inclined plate and the left inner wall of the tank form the aforementioned small-capacity soaking chamber.

[0010] An inclined partition is provided below the bottom plate in the tank. The inclined partition is inclined downward from left to right, and the left end of the inclined partition is fixedly engaged with the left inner wall of the tank. The right end of the inclined partition is fixedly engaged with the inner bottom wall of the tank. The top surface of the inclined partition is the inclined surface. The bottom plate and the inclined partition form the lower chamber. The right inner bottom wall of the tank, the right inner wall of the tank, and the inclined partition form the right chamber.

[0011] An installation plate protrudes to the right from the upper right side of the inclined plate, and the transition wheel is rotatably mounted on the top surface of the installation plate.

[0012] Vertical plates are erected at both ends of the right side of the top surface of the trough, and the two vertical plates are located within the right chamber. The aforementioned guide wheel is rotatably mounted between the two vertical plates on the right side of the top surface of the trough. The vertical plates are recessed with a strip-shaped groove that extends vertically and passes through horizontally. The two ends of the upper row of guide wheels are fitted with mounting blocks. The mounting blocks have insert pieces and mounting pieces. The part of the vertical plate below the strip-shaped groove is clamped between the insert pieces and the mounting pieces, and the upper ends of the insert pieces and the mounting pieces extend upward beyond the bottom of the strip-shaped groove. The two insert pieces are located between the two mounting pieces. The insert pieces are recessed with rotating holes. The two ends of the upper row of guide wheels extend into the rotating holes and are rotatably mounted on the insert pieces. The extrusion mechanism is mounted on the two vertical plates in a manner that allows it to move up and down to approach the upper row of guide wheels.

[0013] The extrusion mechanism has an extrusion roller, and sliding blocks are sleeved at both ends of the extrusion roller. The sliding blocks are slidably installed in the strip groove. The top surface of the vertical plate is provided with a translation drive device for controlling the up and down movement of the sliding blocks. The output end of the translation drive device is connected to the sliding blocks. The outer diameter of the upper row of guide wheels is larger than the outer diameter of the mounting block, and a limiting block is provided between the mounting block and the sliding block. The limiting block is stacked on the top surface of the mounting block.

[0014] The two opposite inner walls of the strip groove are each provided with a limiting protrusion to limit the sliding block, and the limiting protrusion is located above the upper row of guide wheels.

[0015] This novel impregnation tank reduces waste material. In application, the leather base fabric is transported to a small-capacity impregnation chamber by an inlet wheel, passing through a first lower guide wheel and then a transition wheel. During transport, the flared structure of the small-capacity impregnation chamber adapts to the first arc-shaped space formed by the leather base fabric from the inlet wheel to the first lower guide wheel and the transition wheel, improving the utilization rate of the impregnation liquid in the small-capacity impregnation chamber and preventing excessive waste of impregnation liquid outside the first arc-shaped space. After passing the transition wheel, the leather base fabric passes through a second lower guide wheel in a large-capacity impregnation chamber for secondary impregnation before passing through an upper guide wheel. A second arc-shaped space is formed between the transition wheel and the second lower guide wheel and the upper guide wheel. The inclined partition in the large-capacity impregnation chamber prevents excessive waste of impregnation liquid outside the second arc-shaped space, thus improving the overall impregnation liquid utilization rate within the impregnation chamber. In terms of utilization, as the leather base fabric passes through the upper guide rollers, the driving extrusion mechanism moves downward, thereby extruding the leather base fabric above the upper guide rollers. Finally, driven by the guide rollers, the base fabric is discharged. Compared with the existing technology, the soaking liquid volume in the soaking chamber is smaller than that in the original rectangular chamber. Moreover, the horn structure of the small-capacity soaking chamber and the inclined surface of the large-capacity soaking chamber can adapt to the arc-shaped space formed by the leather base fabric during the transportation process, which is smaller at the bottom and larger at the top. This prevents excessive waste of soaking liquid outside the arc-shaped space in the soaking chamber and improves the utilization rate of soaking liquid without affecting the soaking of the leather base fabric. It also reduces the amount of residual soaking liquid when it needs to be replaced, effectively controlling the amount of residual soaking liquid and reducing waste. The reduction in soaking liquid also makes operation and cleaning more convenient for operators. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the structure of this utility model.

[0017] Figure 2 This is another structural schematic diagram of the present invention. Detailed Implementation

[0018] To further explain the technical solution of this utility model, a detailed description is provided below in conjunction with the accompanying drawings.

[0019] An impregnation tank that reduces residue, such as Figure 1-2As shown, the system includes a tank 1, which is a hollow shell with an open top. The hollow cavity of the tank 1 is a soaking chamber for placing soaking liquid. One side of the top surface of the tank 1 is provided with an inlet wheel 11, and the other side is provided with an outlet wheel 12. The soaking chamber is provided with guide wheels, including an upper row of guide wheels 2 above the surface of the soaking liquid and a lower row of guide wheels 3 below the surface of the soaking liquid. A squeezing mechanism is provided above the upper row of guide wheels 2. In application, the leather base fabric is transported into the soaking chamber by the inlet wheel 11, and then soaked in the soaking liquid by the lower row of guide wheels 3 below the liquid surface. Then, under the squeezing of the upper row of guide wheels and the squeezing mechanism above the liquid surface, the soaking liquid is squeezed out. Finally, the base fabric is transported to the next process by the outlet wheel 12.

[0020] With the side of tank 1 with the inlet wheel 11 as the left and the side with the outlet wheel 12 as the right, a partition plate 4 is provided on the left side of the hollow cavity of tank 1 to divide the hollow cavity of tank 1 into two chambers. One of the two chambers is a horn-shaped chamber 100 that gradually expands from bottom to top. The horn-shaped chamber 100 is a small-capacity immersion chamber. Specifically, tank 1 is a hollow strip structure extending in the front-back direction. The partition plate 4 has a lower bottom plate 41 that is fixedly fitted with the left inner wall of tank 1 and a right side that is connected to the lower bottom plate 41 and inclined upwards. The inclined plate 42 and the lower bottom plate 41 are rectangular plates extending in the front-back direction. The lower bottom plate 41 is suspended above the lower bottom wall of the tank. The left side of the lower bottom plate 41 is locked to the left inner wall of the tank. The lower bottom plate 41, the inclined plate 42 and the left inner wall of the tank 1 form the small-capacity soaking chamber. In application, the small-capacity soaking chamber is shaped like a trumpet chamber. Compared with a square chamber of the same length, width and height, the volume of the trumpet chamber is smaller for the same height of soaking liquid. The trumpet chamber liquid can also accommodate the soaking of leather base fabric in the small-capacity chamber.

[0021] Another chamber includes a lower chamber 200 located below the horn chamber 100 and a right chamber 300 connected to the lower chamber 200 and located to the right of the horn chamber 100. The lower chamber 200 and the right chamber 300 form a large-capacity soaking chamber. The inner bottom surface of the large-capacity soaking chamber is inclined from left to right. The small-capacity soaking chamber and the large-capacity soaking chamber constitute the soaking chamber. Specifically, an inclined partition 13 is provided below the lower bottom plate 41 in the tank 1. The inclined partition 13 is inclined downward from left to right, and the left end of the inclined partition 13 is fixedly engaged with the left inner wall of the tank 1, and the right end of the inclined partition 13 is fixedly engaged with the inner bottom wall of the tank 1. The lower bottom plate 41 and the inclined partition 13 are inclined downward from left to right. The partition 13 forms the lower chamber 200, and the top surface of the inclined partition 13 is the inclined surface. The right inner bottom wall of the tank 1, the right inner tank wall of the tank 1, and the inclined plate 42 form the right chamber 300. During application, as the leather base fabric is soaked, the soaking liquid continuously decreases and the liquid level drops. Under the action of the inclined partition, the lower chamber 200 forms a chamber that is larger at the top and smaller at the bottom. When the liquid level drops, the soaking liquid in the lower chamber falls into the right chamber, making the utilization rate of the soaking liquid in the lower chamber higher. It also makes the soaking liquid in the large-capacity soaking chamber less than that in a square chamber of the same length, width, and height, without affecting the further soaking of the leather base fabric.

[0022] The lower guide wheel 3 has a first lower guide wheel 31 and a second lower guide wheel 32. The first lower guide wheel 31 is rotatably installed in the small-capacity soaking chamber, and the second lower guide wheel 32 is rotatably installed in the right chamber 300. The upper guide wheel 2 is located above and to the right of the second lower guide wheel 32. Specifically, vertical plates 14 are erected at both ends of the front and rear of the right side of the top surface of the tank 1. The two vertical plates are located within the right chamber. The guide wheel 12 is rotatably installed on the right side of the top surface of the tank 1 and is located between the two vertical plates 14. The guide wheel is located on the left side of the top surface of the tank and is located outside the left side of the vertical plate. The method of rotating and suspending the guide wheel 11 and the guide wheel 13 on the top surface of the tank is a well-known technique to those skilled in the art and will not be described in detail here. The vertical plate 14 has a recessed groove extending vertically and penetrating horizontally. The upper row of guide wheels is rotatably mounted between the two vertical plates. Specifically, mounting blocks 5 are fitted over both ends of the upper row of guide wheels 2. Each mounting block 5 has an insert piece 51 and a mounting piece 52. The portion of the vertical plate 14 below the groove is clamped between the insert piece 51 and the mounting piece 52, with the insert piece 51 and the mounting piece 52 extending upwards beyond the bottom of the groove. The two insert pieces 51 are positioned between the two mounting pieces 52, and both are locked to the vertical plate. The insert piece 51 has a recessed rotating hole. Both ends of the upper row of guide wheels 2 extend into the rotating hole and are rotatably mounted on the insert piece 51. The pressing mechanism is installed in a manner that allows it to move vertically closer to the upper row of guide wheels 2. On the two vertical plates 14, the extrusion mechanism has extrusion rollers 6, which are positioned above and parallel to the upper row of guide wheels 2. Sliding blocks 61 are sleeved on both ends of the extrusion rollers 6, positioned directly above the mounting block 5. The sliding blocks 61 are slidably mounted within a strip groove, meaning that sliding grooves are recessed on both the left and right end faces of the sliding blocks. The inner walls of the strip groove are in contact with the bottom of the sliding groove. The top surface of the vertical plates 14 is equipped with a translation drive device for controlling the up-and-down movement of the sliding blocks 61. The translation drive device is a translation cylinder, positioned downwards, with its output end extending downwards into the strip groove and connecting to the sliding block 61. Preferably, the outer diameter of the upper row of guide wheels 2 is larger than the outer diameter of the mounting block 5. A limiting block 53 is provided between the mounting block 5 and the sliding block 61, and the limiting block is stacked on the top surface of the mounting block 5. In application, the setting of the insert piece 51 and the mounting piece 52 allows the upper row of guide wheels to rotate and be installed between the two vertical plates, which also facilitates the disassembly and installation of the upper row of guide wheels. Drive the translation cylinder, and the extrusion roller moves downward under the drive of the translation cylinder. At the same time, under the limiting action of the limiting block 53, the extrusion roller will not get too close to the leather base fabric, which would cause the leather base fabric to deform. Meanwhile, the guide wheel 12 is on the right side of the extrusion roller and the upper row of guide wheels. After the leather base fabric is soaked in the soaking liquid, under the squeezing action of the upper row of guide wheels and the extrusion roller, the soaking liquid is squeezed out and then discharged through the guide wheel, which can squeeze out the excess soaking liquid on the leather base fabric and reduce the loss of soaking liquid.

[0023] The top surface of the partition plate 4 is rotatably mounted with a transition wheel 7 located between the first lower guide wheel 31 and the second lower guide wheel 32. Specifically, the upper right side of the inclined plate 42 has a mounting plate 421 protruding to the right, and the transition wheel 7 is rotatably mounted on the top surface of the mounting plate 421. The way the transition wheel is rotatably mounted on the mounting plate is similar to the way the guide wheel is mounted, so it will not be described in detail here. In application, the setting of the transition wheel prevents the leather base fabric from being scratched by the top surface of the inclined plate 42 when it transitions from the first lower guide wheel 31 to the second lower guide wheel 32. At the same time, when the leather base fabric passes through the transition wheel, it also exerts a certain squeezing effect on the soaking liquid on the leather base fabric.

[0024] This novel impregnation tank for reducing waste material, in application, involves a leather base fabric being transported to a small-capacity impregnation chamber by an inlet wheel 11, passing through a first lower guide wheel 31 and then over a transition wheel 7. During transport, the flared structure of the small-capacity impregnation chamber adapts to the first arc-shaped space formed by the leather base fabric from the inlet wheel 11 to the first lower guide wheel and the transition wheel 7, improving the utilization rate of the impregnation liquid in the small-capacity impregnation chamber. After passing through the transition wheel 7, the leather base fabric undergoes a second impregnation by passing through a second lower guide wheel 32 in a large-capacity impregnation chamber before passing through an upper guide wheel 2. A second arc-shaped space is also formed between the transition wheel 7 and the second lower guide wheel 32 and the upper guide wheel. The inclined partition in the large-capacity impregnation chamber prevents excessive waste of the impregnation liquid outside the second arc-shaped space, improving the overall utilization rate of the impregnation liquid in the impregnation chamber. When the upper guide rollers are in operation, the driving translation drive device moves the squeezing roller 6 downward, thereby squeezing the leather base fabric passing above the upper guide rollers 2. Finally, the base fabric is discharged under the drive of the discharge roller. Compared with the prior art, the volume of soaking liquid in the soaking chamber is smaller than that in the original rectangular chamber. Moreover, the horn structure of the small-capacity soaking chamber and the inclined partition 13 of the large-capacity soaking chamber can adapt to the arc-shaped space formed by the leather base fabric during the transportation process. This prevents excessive waste of soaking liquid outside the arc-shaped space in the soaking chamber and does not affect the soaking of the leather base fabric. This improves the utilization rate of soaking liquid and reduces the amount of residual soaking liquid when it needs to be replaced. This effectively controls the amount of residual soaking liquid and reduces waste. The reduction in soaking liquid makes operation and cleaning more convenient for operators.

[0025] In this invention, the superior feature is that each of the two opposite inner groove walls of the strip groove is provided with a limiting protrusion 131 to limit the sliding block 61. The limiting protrusion 131 is located above the upper row of guide wheels 2. In application, when the driving translation cylinder moves downward to drive the extrusion roller downward, under the further limiting effect of the limiting protrusion 131, the extrusion roller will not collide with the upper row of guide wheels, while maintaining a certain distance between the extrusion roller and the upper row of guide wheels for the leather base fabric to pass through.

[0026] In this novel design, a partition 15 is provided on the right side of the hollow chamber of the tank. The partition 15 is inclined upwards from left to right. The lower end of the partition 15 is connected to the inner bottom wall of the tank 1, and the upper end of the partition 15 is connected to the right inner side wall of the tank 1. The partition 15 and the inclined partition 13 form a horn-shaped space that gradually narrows from bottom to top. In application, the inclined partition 13 further divides the right chamber, making the large-capacity soaking chamber form a horn-shaped space that gradually narrows from bottom to top. This can accommodate the horn-shaped structure formed by the leather base fabric transitioning from the transition wheel 7 to the second lower row of guide wheels 32 and then to the upper row of guide wheels 2, reducing the amount of soaking liquid in the large-capacity soaking chamber and improving the utilization rate of the soaking liquid.

[0027] The product form of this utility model is not limited to the illustrations and embodiments in this case. Any appropriate changes or modifications made to it based on similar ideas should be considered as not departing from the patent scope of this utility model.
