Description

Technical Field

[0001] The invention relates to the technical field of livestock fur processing equipment, and in particular to a low-alkali cowhide hair removal integrated machine and a use method thereof. Background Art

[0002] Generally speaking, cowhide refers to the skin from a cow. The skin is cut from the cow, and then goes through a series of processes from wet to dry, and then the dry skin is made into products of various styles. Cowhide is more widely used in various industries, and the most commonly used ones are of course: leather shoes, leather bags, belts and other leather goods; at the same time, there are also many other industries that use cowhide products; for example: car steering wheel covers, leather notebook cases, suitcases, jewelry boxes, cigar cases, sports equipment packaging, etc., which are trend pioneers in all walks of life.

[0003] Before cowhide is cut into products, the hair on its surface needs to be dehaired. Most of the existing cowhide dehairing equipment drives the cowhide to rotate by rotating rollers and removes the hair by squeezing with a shovel. In actual operation, due to the flexibility of the cowhide, wrinkles will appear when squeezed by the shovel, thus affecting the scraping effect of the shovel. At the same time, the efficiency of dehairing cowhide by single squeezing with a shovel needs to be further improved. Summary of the invention

[0004] The present invention discloses a low-alkali cowhide hair removal all-in-one machine and a method for using the machine, aiming to solve the technical problem that, during actual operation of the existing cowhide hair removal equipment, due to the influence of the flexibility of the cowhide, wrinkles will appear when the cowhide is squeezed by a shovel plate, thereby affecting the operation efficiency of the equipment, and at the same time, the efficiency of hair removal of the cowhide by a single squeezing method of the shovel plate needs to be further improved.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A low-alkali depilatory machine for cowhide, comprising a machine body, a rotating roller rotatably mounted inside the machine body, a motor for driving the rotating roller mounted on the top of the machine body, an electric control fixture arranged inside the rotating roller, and a shovel plate obliquely mounted inside the machine body, a driving mechanism is arranged inside the machine body, the driving mechanism comprises a shaft mounted inside the machine body, the shaft is distributed on the top of the rotating roller, both ends of the shaft are rotatably sleeved with socket parts, and a roller is rotatably mounted at the bottom of each socket part; An auxiliary mechanism is arranged on the side of the driving mechanism, and the auxiliary mechanism comprises a smoothing roller rotatably mounted between the two rollers, the smoothing roller is a hollow structure, a liquid guide tube is rotatably mounted on the end of the smoothing roller, and the liquid guide tube penetrates through the end of the machine body; The driving mechanism is utilized to drive the auxiliary mechanism to flip over, and the cowhide is smoothed and washed when the rotating roller is working.

[0006] By arranging a driving mechanism and an auxiliary mechanism inside the machine body, when the rotating roller drives the cowhide to rotate and is squeezed and depilated by the shovel, the driving mechanism can realize self-starting along with the rotation of the rotating roller, thereby driving the auxiliary mechanism to rotate and squeeze the surface of the cowhide, so as to smooth the cowhide and prevent wrinkles from appearing on the surface of the cowhide when the shovel scrapes the cowhide. At the same time, along with the squeezing contact between the auxiliary mechanism and the cowhide, the external guide device can spray the heated sodium sulfide and lime mixed solution onto the surface of the cowhide through the auxiliary mechanism, thereby further performing alkaline depilation on the cowhide, and further improving the working efficiency of the equipment.

[0007] In a preferred embodiment, the driving mechanism further comprises a flange member sleeved and fixed at the end of the rotating roller, the roller and the flange member are in extrusion contact, and the auxiliary mechanism is arranged between the two sleeve members and forms an extrusion contact with the outer surface of the rotating roller.

[0008] An axial rod structure with an assembled sleeve is additionally fixed inside the machine body, and a flange structure is additionally sleeved on the end of the rotating roller. When the rotating roller rotates, the flange is also driven to rotate. Through the extrusion relationship between the flange and the roller at the bottom of the sleeve, the sleeve is driven to rotate around the axial rod, thereby driving the auxiliary mechanism to synchronously revolve and squeeze the surface of the cowhide, so as to smooth the cowhide and prevent wrinkles on the surface of the cowhide when the shovel is scraped off, thereby ensuring the integrity of the equipment operation.

[0009] In a preferred solution, the auxiliary mechanism further comprises a plurality of oblique spray holes which are obliquely distributed on the outer side of the smoothing roller, and the oblique spray holes are divided into two groups and are symmetrically distributed on both sides of the smoothing roller.

[0010] A smoothing roller structure is installed by rotating between the bottoms of two sockets, and the rotation of the sockets is used to drive the smoothing roller to synchronously revolve and squeeze the surface of the cowhide, so as to smooth the cowhide and prevent wrinkles on the surface of the cowhide when the shovel is scraped off the cowhide, thereby ensuring the integrity of the equipment operation. At the same time, a liquid guide pipe structure is connected to the end of the smoothing roller, and the heated sodium sulfide and lime mixed solution is introduced into the liquid guide pipe and sprayed onto the surface of the cowhide through two groups of inclined spray holes, so as to further perform alkaline depilation on the cowhide. The obliquely distributed inclined spray holes can spray and wash away the adhered cow hair to both sides, thereby further improving the working efficiency of the equipment.

[0011] In a preferred embodiment, the flange member includes a flange ring which is sleeved and fixed on both ends of the rotating roller, the outer side of the flange ring is provided with an inner concave section, the outer side of the inner concave section is provided with an outer arc section, and the roller is squeezed and contacted with the inner concave section and the outer arc section.

[0012] By providing a flange ring structure with an outer arc section and an inner concave section, the flange ring is driven to rotate simultaneously by a rotating roller, thereby changing the positional relationship between the outer arc section, the inner concave section and the roller wheel, causing the sleeve to be pushed and folded, thereby ensuring the integrity of the operation of the equipment.

[0013] As can be seen from the above, the cowhide low-alkali depilatory machine and its use method provided by the present invention have the following improvements and advantages compared with the prior art: An axial rod structure with an assembly sleeve is additionally fixed inside the machine body, and a flange structure is additionally sleeved on the end of the rotating roller. When the rotating roller rotates, the flange is also driven to rotate. Through the extrusion relationship between the flange and the roller at the bottom of the sleeve, the sleeve is driven to rotate around the axial rod, thereby driving the smoothing roller to synchronously revolve and squeeze the surface of the cowhide to smooth the cowhide, thereby preventing wrinkles on the cowhide surface when the shovel is scraped off the cowhide, thereby ensuring the integrity of the equipment operation. At the same time, a liquid guide pipe structure is connected through the end of the smoothing roller, and the heated sodium sulfide and lime mixed solution is introduced into the liquid guide pipe and sprayed onto the surface of the cowhide through two groups of inclined spray holes, thereby further alkaline depilation of the cowhide, and the inclined spray holes can spray and wash away the adhered cow hair to both sides, thereby further improving the working efficiency of the equipment.

DETAILED DESCRIPTION

[0024] 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 the embodiments.

[0025] The low-alkali cowhide hair removal integrated machine and the use method thereof disclosed in the present invention are mainly used in the cowhide hair removal processing scenario.

[0026] Reference Figures 1 to 9 A low-alkali depilatory machine for cowhide comprises a machine body 1, a rotating roller 2 rotatably mounted inside the machine body 1, a motor 3 for driving the rotating roller 2 mounted on the top of the machine body 1, an electric control fixture 4 arranged inside the rotating roller 2, and a shovel plate 5 obliquely mounted inside the machine body 1, a driving mechanism 6 is arranged inside the machine body 1, and the driving mechanism 6 comprises a shaft 601 mounted inside the machine body 1, the shaft 601 is distributed on the top of the rotating roller 2, both ends of the shaft 601 are rotatably sleeved with sockets 602, and a roller 603 is rotatably mounted on the bottom of each socket 602; An auxiliary mechanism 7 is provided on the side of the driving mechanism 6. The auxiliary mechanism 7 includes a smoothing roller 701 rotatably mounted between two rollers 603. The smoothing roller 701 is a hollow structure. A liquid guide tube 703 is rotatably mounted on the end of the smoothing roller 701. The liquid guide tube 703 penetrates from the end of the machine body 1. The auxiliary mechanism 7 is turned over by the driving mechanism 6, and the cowhide is smoothed and washed when the rotating roller 2 is working.

[0027] In this embodiment: the operator holds both sides of one end of the cowhide and lays the cowhide on the outside of the rotating roller 2, and at the same time inserts the end of the cowhide into the inside of the electric-controlled clamp 4, and starts the electric-controlled clamp 4 to clamp and fix the cowhide to be cleaned, and then starts the entire equipment. At this time, the motor 3 rotates and synchronously drives the rotating roller 2. The rotating roller 2 will drive the cowhide to rotate, and the cowhide that rotates synchronously will be scraped by the shovel plate 5 to remove the hair. While the rotating roller 2 drives the cowhide to rotate, the driving mechanism 6 will start automatically and drive the auxiliary mechanism 7 to flip, squeeze the surface of the cowhide and smooth the cowhide with the relative rotation of the rotating roller 2. While the auxiliary mechanism 7 smoothes the cowhide, it will slowly spray a mixed solution of sodium sulfide and lime on the surface of the cowhide through a diversion device connected to the outside of the equipment, and while assisting the cowhide in removing the hair, the fallen cow hair will be washed to both ends of the rotating roller 2.

[0028] It should be additionally explained that a blanking plate 9 is fixedly installed inside the machine body 1 , and the blanking plate 9 is obliquely distributed below the rotating roller 2 , and the cow hair falling from both ends of the rotating roller 2 will be received by the blanking plate 9 .

[0029] Further, it is supplemented that a belt 8 is connected between the output end of the motor 3 and the end of the rotating roller 2 .

[0030] In the above scheme, considering that the cowhide is flexible, it will be deformed when squeezed by the shovel plate 5, thereby affecting the effect of the hair removal treatment of the entire cowhide. The surface of the cowhide needs to be smoothed, and the specific operation is as follows.

[0031] Reference Figures 2 to 4 , Figures 6 to 8 In a preferred embodiment, the driving mechanism 6 also includes a flange 604 fixed to the end of the rotating roller 2, the roller 603 and the flange 604 are in extrusion contact, and the auxiliary mechanism 7 is arranged between the two sleeves 602 and forms an extrusion contact with the outer surface of the rotating roller 2.

[0032] In this embodiment: along with the rotation of the rotating roller 2, the flange 604 located at the end of the rotating roller 2 will rotate synchronously, and at the same time, squeeze and push the roller 603 at the bottom of the socket 602, so that the socket 602 rotates around the shaft 601, driving the auxiliary mechanism 7 to press down and squeeze the cowhide in contact with the surface of the rotating roller 2. At this time, along with the continuous rotation of the rotating roller 2, the shovel plate 5 squeezes and removes the hair on the surface of the cowhide, and the auxiliary mechanism 7 smoothes the unextruded parts of the cowhide, thereby preventing the cowhide from wrinkles, and the roller 603 continues to rotate along the surface of the flange 604.

[0033] In the above scheme, in order to further improve the depilatory efficiency of the shovel plate 5 on the cowhide, the specific operation is as follows.

[0034] Reference Figures 1 to 4 , Figure 6 In a preferred embodiment, the auxiliary mechanism 7 also includes a plurality of oblique spray holes 702 which are obliquely distributed on the outer side of the smoothing roller 701 . The oblique spray holes 702 are divided into two groups and are symmetrically distributed on both sides of the smoothing roller 701 .

[0035] In this embodiment, the sleeve 602 rotates around the shaft 601, driving the smoothing roller 701 to press down and squeeze the cowhide in contact with the surface of the rotating roller 2. At this time, with the continuous rotation of the rotating roller 2, the shovel plate 5 squeezes and removes the hair on the surface of the cowhide, while the smoothing roller 701 smoothes the unpressed parts of the cowhide and rotates synchronously under the influence of the friction of the cowhide, thereby preventing the cowhide from wrinkling. At this time, the operator starts the diversion device additionally connected to the liquid guide tube 703, and the heated vulcanized The mixed solution of sodium and lime is introduced into the interior of the smoothing roller 701, and sprayed onto the surface of the cowhide through two groups of inclined spray holes 702, so as to further perform alkaline heating and hair removal on the cowhide. At the same time, the oblique spray holes 702 distributed obliquely can spray and wash away the adhered cow hair to both sides, causing the cow hair to fall off to the inside of the blanking plate 9; wherein, an adapter 704 is rotatably connected between the end of the smoothing roller 701 and the liquid guide tube 703, and a movable groove 705 is penetrated at the end of the body 1, and the liquid guide tube 703 passes through the inside of the movable groove 705.

[0036] Reference Figure 8 In a preferred embodiment, the flange member 604 includes a flange ring 6041 which is sleeved and fixed on both ends of the rotating roller 2, an inner concave section 6042 is provided on the outer side of the flange ring 6041, an outer arc section 6043 is provided on the outer side of the inner concave section 6042, and the roller 603 is squeezed and contacted with the inner concave section 6042 and the outer arc section 6043.

[0037] In this embodiment: in the initial state, the roller 603 is distributed inside the concave interval 6042. As the rotating roller 2 rotates, the flange 604 located at the end of the rotating roller 2 will rotate synchronously, and at the same time, the roller 603 at the bottom of the socket 602 is squeezed and pushed, causing the roller 603 to gradually move from the inside of the concave interval 6042 to the surface of the outer arc interval 6043. During the transition from the concave interval 6042 to the outer arc interval 6043, the socket 602 pushed by the roller 603 will gradually rotate, causing the smoothing roller 701 to be squeezed and contacted with the surface of the cowhide.

[0038] Among them, it should be additionally explained that: a torsion spring 605 is fixedly connected between each socket 602 and the end of the shaft 601, and the torsion spring 605 is sleeved on the outer side of the shaft 601. When the roller 603 rotates one circle along the surface of the flange 604 and resets, the torsion spring 605 that loses the extrusion restriction will reset and rotate, thereby driving the socket 602 to rotate synchronously.

[0039] Working principle: When in use, the operator holds both sides of one end of the cowhide and lays the cowhide on the outside of the rotating roller 2, and at the same time inserts the end of the cowhide into the inside of the electric control clamp 4, and starts the electric control clamp 4 to clamp and fix the cowhide to be cleaned, and then starts the whole equipment. At this time, the motor 3 rotates and synchronously drives the rotating roller 2. The rotating roller 2 will drive the cowhide to rotate, and the cowhide that rotates synchronously will be scraped by the shovel plate 5 to remove the hair; while the rotating roller 2 drives the cowhide to rotate, the flange 604 located at the end of the rotating roller 2 will rotate synchronously, and at the same time, it will squeeze and push the roller 603 at the bottom of the socket 602, causing the roller 603 to gradually move from the inside of the concave interval 6042 to the surface of the outer arc interval 6043. In the transition process from the concave interval 6042 to the outer arc interval 6043, the socket 602 pushed by the roller 603 will gradually rotate around the shaft 601, causing the smoothing roller 601 to squeeze and contact the surface of the cowhide (such as Fig. 9 As shown), at this time, along with the continuous rotation of the rotating roller 2, the shovel plate 5 squeezes and removes the hair on the surface of the cowhide, and the smoothing roller 701 smoothes the un-squeezed parts of the cowhide, and rotates synchronously under the influence of the friction of the cowhide, thereby preventing the cowhide from wrinkling. After that, the operator starts the diversion device additionally connected to the liquid guide tube 703, and introduces the heated sodium sulfide and lime mixed solution into the smoothing roller 701 through the liquid guide tube 703, and sprays it onto the surface of the cowhide through two groups of inclined spray holes 702, thereby further alkaline depilating the cowhide. At the same time, the oblique spray holes 702 distributed obliquely can spray and wash away the adhered cow hair to both sides, causing the cow hair to fall to the inside of the blanking plate 9, completing the depilation of the cowhide.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
