Description

Technical Field

[0001] The utility model relates to the field of leather processing, and more specifically, to a leather tanning machine. Background Art

[0002] The process of treating raw hides with tanning agents to turn them into leather is called tanning, which is a key process in leather production. Among the common tanning machines and equipment used in the tanning process in the current leather industry, the most commonly used is the rotary drum. The inner wall of the ordinary rotary drum is equipped with convex piles or leather lifting plates. During operation, the hides and tanning liquid are placed in the drum together. During the rotation of the drum, the hides and tanning liquid roll and throw in the drum, generating mechanical action. This mechanical action can promote the penetration of the tanning liquid into the cortex, accelerate the physical and chemical changes of the hides, and thus achieve the effect of tanning leather.

[0003] At present, the existing leather tanning equipment will bring out a lot of tanning agents when unloading the leather after tanning, and a large amount of tanning agents will remain in the folded parts of the leather. The direct unloading of the tanned leather causes a large amount of tanning agent waste, which increases the production cost. The tanning agent remaining in the leather will increase the weight of the leather, which makes it more difficult for production personnel to take it, thereby increasing the labor intensity of the staff. In addition, the tanning agent will spill on the ground when it is discharged with the leather, causing environmental pollution.

[0004] Based on the above, the purpose of the present utility model is to provide a leather tanning machine to solve the above problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a leather tanning machine. The utility model comprises a connecting sleeve and a rotating sleeve which are mutually socketed and rotatably arranged in a mounting frame. When in use, hides and tanning liquid are poured into the rotating sleeve for tanning. After tanning, the tanning liquid flows into a receiving pool through filter plates 2 and 1 for collection. The hides are then driven to flip in the rotating sleeve by a driving mechanism to discharge excess tanning liquid. The hides are taken out after the tanning liquid collection is completed.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: a leather tanning machine, including a mounting frame, a connecting sleeve is rotatably connected to the mounting frame, a rotating sleeve is rotatably connected inside the connecting sleeve, a plurality of through holes are arranged on the side wall of the rotating sleeve close to the connecting sleeve, a storage pool is arranged on the mounting frame, a filter plate 1 is arranged on the storage pool, a feed trough and a discharge trough are respectively arranged on the mounting frame near the connecting sleeve and the storage pool, a feed and outlet groove is arranged on the rotating sleeve, a through groove and a filter plate 2 are arranged on the connecting sleeve, a plurality of push plates are fixedly connected inside the connecting sleeve, and a driving mechanism that can drive the connecting sleeve or the rotating sleeve to rotate is arranged on the mounting frame.

[0007] By adopting the above technical scheme, when leather tanning operation is needed, the hides and tanning liquid are poured into the rotating sleeve through the feed trough, the through trough and the inlet and outlet trough. Due to the wrapping of the connecting sleeve, the tanning liquid will be stored in the connecting sleeve, and then the rotating sleeve is driven to rotate by the driving mechanism, and the push plate causes the hides and tanning liquid to roll and throw in the rotating sleeve, and then the tanning operation is carried out. When tanning is completed, the connecting sleeve is driven to rotate by the driving mechanism until the filter plate 2 rotates to the side close to the storage pool. At this time, the tanning liquid will pass through the filter plate 2 and the filter plate 1 into the storage pool. The filter plate 1 will collect the impurities in the tanning liquid, and then the rotating sleeve is driven to rotate by the driving mechanism, so that the hides are rotated. The sleeve is turned over and thrown inside the rotating sleeve to throw out the excess tanning liquid attached to the hide. When the tanning liquid is collected, the user can clean the impurities through the discharge chute. Then, the rotating sleeve is rotated to the side of the inlet and outlet slot close to the storage pool. The connecting sleeve is driven to rotate by the driving mechanism until the through slot is rotated to the side close to the storage pool. At this time, the hide will pass through the inlet and outlet slot and the through slot and fall onto the filter plate. The user can then take the hide out through the discharge chute. With this arrangement, the tanning liquid can be automatically collected and impurities can be removed after tanning is completed, which is convenient for the tanning liquid to be reused or subsequently processed. The excess tanning liquid on the hide can also be discharged, which is convenient for the workers to process the hides later and prevents the tanning liquid from spilling and polluting the environment.

[0021] The utility model is described in detail below in conjunction with the accompanying drawings.

[0022] A leather tanning machine, such as Figure 1-Figure 2 As shown, it includes a mounting frame 1, on which a connecting sleeve 2 is rotatably connected, and a rotating sleeve 3 is rotatably connected inside the connecting sleeve 2. A plurality of through holes are provided on the side wall of the rotating sleeve 3 near the connecting sleeve 2, a storage pool 4 is installed on the mounting frame 1, and a filter plate 5 is installed on the storage pool 4. The mounting frame 1 is provided with a feed trough 6 and a discharge trough 7 at positions near the connecting sleeve 2 and the storage pool 4, respectively, an inlet and outlet groove 25 is provided on the rotating sleeve 3, a through groove 9 is provided on the connecting sleeve 2 and a filter plate 2 10 is installed, a plurality of push plates 11 are fixedly connected inside the connecting sleeve 2, and a driving mechanism that can drive the connecting sleeve 2 or the rotating sleeve 3 to rotate is provided on the mounting frame 1.

[0023] Furthermore, the driving mechanism includes a mounting plate 12 slidably connected to the mounting frame 1, an electric push rod 13 is installed on the mounting plate 12, the protruding end of the electric push rod 13 is fixedly connected to the mounting plate 12, a motor 14 is installed on the mounting plate 12, a driving gear 15 is fixedly connected to the output shaft of the motor 14, and a gear ring 16 and a gear ring 2 17 that cooperate with the driving gear 15 are respectively fixedly connected to the connecting sleeve 2 and the rotating sleeve 3.

[0024] Furthermore, a gear ring three 18 is fixedly connected to the connecting sleeve 2, and a limiting gear 19 cooperating with the gear ring three is fixedly connected to the mounting plate 12.

[0025] Furthermore, a water pump 20 and a water inlet pipe 21 are installed on the mounting frame 1. The water inlet and the water outlet of the water pump 20 are connected to the receiving pool 4 and the water inlet pipe 21 respectively. A connecting groove 22 corresponding to the position of the water inlet pipe 21 is opened on the connecting sleeve 2.

[0026] Furthermore, a scraper 23 is provided on the filter plate 1 5 , and an electric push rod 24 is installed on the mounting frame 1 , and the extended end of the electric push rod 24 is fixedly connected to the scraper 23 .

[0027] Furthermore, door panels 8 are rotatably connected to both the feed chute 6 and the discharge chute 7 .

[0028] Working principle: When leather tanning is required, the hides and tanning liquid are poured into the rotating sleeve 3 through the feed trough 6, the through trough 9 and the inlet and outlet trough 25. Due to the wrapping of the connecting sleeve 2, the tanning liquid will be stored in the connecting sleeve 2 and the rotating sleeve 3, and then the driving gear 15 is driven to rotate by the motor 14. The driving gear 15 then drives the rotating sleeve 3 to rotate through the gear ring 2 17, and the limiting gear 19 will limit the gear ring 3 18 at this time, thereby restricting the connecting sleeve 2 from rotating.

[0029] The rotating push plate 11 causes the hides and tanning liquid to tumble and throw in the rotating sleeve 3, thereby tanning the hides. When tanning is completed, the mounting plate 12 is driven to move by the electric push rod 13, so that the driving gear 15 is separated from the gear ring 2 17 and meshed with the gear ring 1 16, and then the connecting sleeve 2 is driven to rotate by the motor 14 until the filter plate 2 10 rotates to the side close to the storage pool 4. At this time, the tanning liquid will pass through the through hole, filter plate 2 and filter plate 1 into the storage pool 4, and the filter plate 1 will block and collect the impurities in the tanning liquid, and then the driving gear 15 is driven by the electric push rod 13 to mesh with the gear ring 2 17, and the limit gear 19 is meshed with the gear ring 3 18, and then the rotating sleeve 3 is driven to rotate, so that the hides are flipped and thrown in the rotating sleeve 3, and then the excess tanning liquid attached to the hides is thrown out.

[0030] When the tanning liquid is collected, the user opens the door panel 8, and then drives the scraper 23 to move toward the discharge trough 7 through the electric push rod 24, thereby discharging the impurities on the filter plate 5 from the discharge trough 7, and then drives the connecting sleeve 2 to rotate to the side of the through groove 9 close to the storage pool 4 through the above method, and then drives the rotating sleeve 3 to rotate to the side of the inlet and outlet groove 25 close to the storage pool 4. At this time, the hides will pass through the inlet and outlet groove 25 and the through groove 9 and fall on the filter plate 5. The user then uses the electric push rod 24 and the scraper 23 to take the hides out of the discharge trough 7. If any hides are stuck in the rotating sleeve 3 and have not been taken out, the feed groove 6, the inlet and outlet groove 25 and the through groove 9 can be adjusted to be mutually conductive, and then the hides can be taken out by tools such as clamps and then added for the next operation. The water pump 20 can send the tanning liquid in the storage pool 4 back to the rotating sleeve 3 for reuse.

[0031] With such an arrangement, the tanning liquid can be automatically collected and impurities removed after tanning is completed, which is convenient for the reuse or subsequent treatment of the tanning liquid. The excess tanning liquid on the hides can also be discharged, which is convenient for the workers to handle the hides later and prevents the tanning liquid from spilling and polluting the environment.

[0032] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
