Description

Technical Field

[0001] The invention relates to the technical field of gelatin production, in particular to a horse hide gelatin production line and a production process. Background Art

[0002] When gelatin is prepared, it is usually packaged using an automated packaging device. However, existing packaging devices can only fill one group of packaging tapes at a time, which greatly prolongs the working time and reduces the working efficiency.

[0003] Chinese patent CN211417692U discloses a gelatin integrated packaging device, including a bottom plate, a first support frame is fixed on the top of the bottom plate by welding, a feed tank is fixed on the top of the first support frame by screws, an inner cavity is arranged in the feed tank, a feed port is arranged on the top of the feed tank, a first motor is fixed to the bottom of the feed tank by screws, a rotating rod is arranged inside the inner cavity, one end of the rotating rod is transmission-connected to the output shaft of the first motor through a coupling, a stirring blade is arranged on the rotating rod, a discharge pipe is arranged on the right side of the stirring blade, the other end of the discharge pipe passes through the outside of the inner cavity, and three groups of discharge heads are fixed by welding, and a self-priming pump is arranged on the discharge pipe.

[0004] The above scheme improves the efficiency of material unloading by increasing the number of unloading heads. However, during packaging, different raw materials will cause different impurities in the gelatin. When there are fewer impurities, they can be directly filtered through the filter, while some animal hair will directly pass through the mesh of the filter because it has not been cleaned in the early stage. If the raw material is horsehide, due to the characteristics of shorter and harder horse hair, if horse hair is mixed in during packaging, it may cause the packaging to be accidentally punctured. When depilating a large amount of horsehide, due to the large amount of hair, the filter will not be directly used for filtration. Instead, the hair and the horsehide are separated by salvaging the hair. The traditional salvaging mechanism is prone to entanglement with the hair when salvaging the hair, which may cause the salvaging mechanism to get stuck. In addition, the traditional salvaging mechanism must leave the depilatory pool after each salvage and discharge the salvaged hair before it can be salvaged again, which is inefficient. Summary of the invention

[0005] In view of the above problems, a horse hide gelatin production line and production process are provided. After aeration by an aeration unit, the hair rolls to the upper layer of the liquid surface of the depilatory pool, and the salvage frame drives the salvage plate to rotate synchronously. When the salvage plate rotates with the salvage frame and is located on the upper side of the salvage frame, the salvage frame is in a closed state. At this time, the axis of the salvage plate coincides with the axis of the salvage frame, that is, the curved surface of the salvage plate coincides with the curved surface of the salvage frame. At this time, the salvage surface of the salvage plate is vertically downward, so that the hair on the salvage surface of the salvage plate can fall into the collecting unit for collection, and then the salvage frame continues to drive the salvage plate to rotate. When the salvage plate rotates to the lower side of the salvage frame, the hair is collected around its own surface. The salvage plate is rotated and opened at the end, and the salvage plate is switched from a closed state to an open state. After being opened, the salvage plate is driven by the salvage frame to sink into the hair removal pool and salvage the hair. As the salvage frame continues to rotate, the salvage plate completes the salvage and switches from an open state to a closed state again. The closed salvage plate puts the hair on its salvage surface into the collecting unit for collection, and then rotates again driven by the salvage frame to sink into the hair removal pool, and the cycle is repeated, so that the salvage unit can continuously salvage the hair in the hair removal pool without the hair entangled in the salvage frame, thereby ensuring that the salvage unit can operate stably, reducing the maintenance rate and improving the salvage efficiency.

When the salvage plate rotates to the lower side with the salvage frame, the salvage plate is in an open state, and the axis of the salvage plate does not coincide with the axis of the salvage frame. At this time, the salvage plate can salvage hair floating in the hair removal pool.

[0037] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0038] Reference Figure 1-Figure 3 and Figure 8-Figure 10 A horse hide gelatin production line, the production steps along the production line sequentially include cleaning equipment, depilatory equipment, pH adjustment equipment, gelatin extraction equipment, filtering equipment, freeze drying equipment and crushing and packaging equipment, wherein the depilatory equipment includes a depilatory pool 1; a salvaging unit 3 for salvaging hair floating in the depilatory area is arranged on the upper part of the depilatory pool 1, the salvaging unit 3 includes a salvaging frame 31 rotatably arranged on the upper part of the depilatory pool 1, the salvaging frame 31 is a cylindrical frame structure, the lower part of the salvaging frame 31 is immersed below the liquid surface of the salvaging pool, and salvaging plates 32 are evenly arranged on the salvaging frame 31 around the axis of the salvaging frame 31, the salvaging plates 32 are arc-shaped structures, one end of the salvaging plate 32 is hinged to the salvaging frame 31, and the hinged The position is the rotation point, and the other end of the salvage plate 32 rotates around the rotation point. When the salvage plate 32 rotates to the upper side with the salvage frame 31, the salvage plate 32 is in a closed state. At this time, the axis of the salvage plate 32 is in a straight line with the axis of the salvage frame 31. When the salvage plate 32 rotates to the lower side with the salvage frame 31, the salvage plate 32 is in an open state, and the axis of the salvage plate 32 does not coincide with the axis of the salvage frame 31. The salvage plate 32 can salvage the hair floating in the hair removal pool 1 at this time. A collecting unit 33 for collecting hair is provided in the salvage frame 31 along the axial direction of the salvage frame 31. After the salvage plate 32 rotates to the upper side with the salvage frame 31, the salvaged hair is put into the collecting unit 33, and the collecting unit 33 outputs the hair.

[0039] Chinese patent CN216753478U discloses a novel edible gelatin production line. The production equipment corresponding to the cleaning equipment, pH adjustment equipment, gelatin extraction equipment, filtering equipment, freeze-drying equipment and crushing and packaging equipment are all existing equipment, so they are not described here. The present invention mainly improves the equipment used in the depilatory equipment. The angle of rotation of the salvage plate 32 from the closed state to the open state is not greater than 90 degrees. A driving unit 311 for driving the salvage frame 31 to rotate is provided on one side of the salvage frame 31. The driving unit 311 includes a first gear ring 3111, a first gear 3112 and a rotating driver 3113. The first gear ring 3111 is fixedly arranged at the end of the salvage frame 31. The first gear 3112 is rotated. The first gear 3112 is disposed on one side of the first gear ring 3111 and meshes with the first gear ring 3111. The rotary driver 3113 is disposed at the end of the first gear 3112. The rotary driver 3113 is used to drive the first gear 3112 to rotate. The rotary driver 3113 is preferably a servo motor. When the rotary driver 3113 is started, the rotary driver 3113 drives the first gear 3112 to rotate, thereby causing the first gear ring 3111 to drive the salvage frame 31 to rotate. Filter holes are provided on the salvage plate 32. An aeration unit 2 is provided in the depilatory pool 1. Since the aeration unit 2 is a prior art, the structure of the aeration unit 2 is not repeated here. The aeration unit 2 is started after the horse hide is put into the depilatory pool 1. The aeration unit 2 aerates the horse hide in the depilatory pool 1 through aeration. Driven to roll, when in use, the horse hide that has not been depilated is put into the depilatory pool 1, and then the aeration unit 2 arranged in the depilatory pool 1 is started, and the aeration unit 2 provides a driving force for the horse hide in the depilatory state, so that the horse hide can continue to roll while depilating, thereby ensuring the uniformity of depilation of the horse hide, and the aeration unit 2 can not only drive the horse hide to roll but also make the hair detached from the horse hide continuously roll to the upper side of the liquid surface of the depilatory pool 1, so that the salvage unit 3 can salvage the hair that has rolled to the upper layer of the depilatory pool 1. The working principle of the salvage unit 3 is as follows: after aeration by the aeration unit 2, the hair rolls to the upper layer of the liquid surface of the depilatory pool 1, and the salvage frame 31 drives the salvage plate 32 to rotate synchronously, and the salvage plate 32 rotates with the salvage frame 31 and is located on the salvage frame 31. The salvage plate 32 is in the closed state when the salvage plate 32 is on the upper side of the salvage frame 31. At this time, the axis of the salvage plate 32 coincides with the axis of the salvage frame 31, that is, the curved surface of the salvage plate 32 coincides with the curved surface of the salvage frame 31. At this time, the salvage surface of the salvage plate 32 is vertically facing downward, so that the hair on the salvage surface of the salvage plate 32 can fall into the collecting unit 33 for collection. Then the salvage frame 31 continues to drive the salvage plate 32 to rotate. When the salvage plate 32 rotates to the lower side of the salvage frame 31, it rotates around one end of itself to open, and the salvage plate 32 switches from the closed state to the open state. After opening, the salvage plate 32 is driven by the salvage frame 31 to sink into the hair removal pool 1 and salvage the hair. As the salvage frame 31 continues to rotate, the salvage plate 32 completes the salvage and switches from the open state to the closed state again.After closing, the salvage plate 32 puts the hair on its salvage surface into the collection unit 33 for collection, and then rotates again under the drive of the salvage frame 31 and sinks into the hair removal pool 1, and the cycle is repeated, so that the salvage unit 3 can continue to salvage the hair in the hair removal pool 1, and the hair will not entangle the salvage frame 31, ensuring that the salvage unit 3 can operate stably, reducing the maintenance rate and improving the salvage efficiency.

[0040] Reference Figure 8 and Fig. 9 A rotating unit 34 for driving the rotating unit 34 to rotate is provided at one end of the salvage plate 32. The rotating unit 34 includes a second gear 341 fixedly provided at the end of the rotating part and an arc-shaped rack 342 provided at one side of the second gear 341. The arc-shaped rack 342 is located at the lower side of the salvage frame 31. The second gear 341 and the arc-shaped rack 342 are meshed with each other. When the salvage frame 31 rotates, the salvage frame 31 drives the second gear 341 to rotate synchronously. When the second gear 341 passes through the arc-shaped rack 342, it drives the salvage plate 32 to rotate. Before the second gear 341 passes through the arc-shaped rack 342, the salvage plate 32 is in a closed state. After the second gear 341 passes through the arc-shaped rack 342, the salvage plate 32 is in an open state.

[0041] Since the second gear 341 is fixedly arranged at the end of the rotation position, when the salvage frame 31 drives the salvage plate 32 to rotate, the second gear 341 arranged on the salvage plate 32 rotates around the axis of the salvage frame 31 together with the salvage plate 32. When the salvage plate 32 drives the second gear 341 to pass through the arc-shaped rack 342, the second gear 341 and the arc-shaped rack 342 engage with each other, and the second gear 341 rolls on the arc-shaped rack 342 driven by the salvage frame 31, so that the second gear 341 can drive the salvage plate 32 to rotate, thereby causing the salvage plate 32 to rotate from a closed state to an open state.

[0042] Reference Figure 8 A maintaining unit 35 is provided on one side of the rotating unit 34. When the salvaging plate 32 passes through the arc-shaped rack 342, it rotates from a closed state to an open state. When the salvaging plate 32 passes through the position of the maintaining unit 35, the maintaining unit 35 locks the salvaging plate 32 in the open state.

[0043] Reference Figure 8 and Fig. 9The maintaining unit 35 comprises an arc plate 351 and a maintaining block 352. The axis of the arc plate 351 is colinear with the axis of the salvage frame 31. The arc plate 351 is arranged on the lower side of the salvage frame 31. The maintaining block 352 is arranged at the end of the second gear 341. An arc-shaped cutout having the same arc as the inner ring of the arc plate 351 is cut on the peripheral wall of the maintaining block 352. After the salvage plate 32 rotates from a closed state to an open state, the arc-shaped cutout on the maintaining block 352 just slides into the inner ring side of the arc plate 351. At this time, the maintaining block 352 and the arc plate 351 are slidably matched, and the salvage plate 32 cannot rotate.

[0044] Reference Figure 8 and Fig.11 A coil spring box 36 is provided at the end of the rotation part. The coil spring in the coil spring box 36 is in a loose state when the salvage plate 32 is in a closed state, and the coil spring in the coil spring box 36 is in a tightened state when the salvage is in an open state.

[0045] Before the salvage frame 31 drives the salvage plate 32 to pass through the arc-shaped rack 342, the coil spring in the coil spring box 36 is in a relaxed state. When the salvage frame 31 drives the salvage plate 32 to pass through the arc-shaped rack 342, the second gear 341 disposed at the end of the salvage plate 32 meshes with the arc-shaped rack 342. When the salvage frame 31 rotates, the second gear 341 meshed with the arc-shaped rack 342 rolls on the arc-shaped rack 342, so that the salvage plate 32 completes its rotation, that is, the salvage plate 32 is moved from the closed state to the closed state. The salvage plate 32 gradually rotates from the open state to the open state. After the salvage frame 31 drives the salvage plate 32 to salvage the hair in the hair removal pool 1, the salvage plate 32 gradually rises driven by the salvage frame 31. At this time, the maintaining block 352 set at the end of the salvage plate 32 gradually slides away from the arc-shaped plate 351. When the maintaining block 352 completely slides away from the arc-shaped plate 351, the coil spring wound in the coil spring box 36 drives the salvage plate 32 to rotate in the opposite direction, so that the salvage plate 32 rotates and resets, that is, at this time, the salvage plate 32 switches from the open state to the closed state.

[0046] Reference Figure 6 , Figure 7 , Fig.11 , Fig.12 and Fig.13 A cleaning unit 37 is provided in the salvage frame 31, and a plurality of retractable cleaning rods 371 are provided on the cleaning unit 37. When the cleaning rods 371 are extended, the hair on the salvage surface of the salvage plate 32 is cleaned, and when the cleaning rods 371 are retracted, the hair entangled on the cleaning rods 371 are wiped off.

[0047] The cleaning unit 37 further includes a second gear ring 373, a third gear 374, a fourth gear 375, an inner shell 376, an outer shell 377, an electromagnet 378 and a magnetic block. The second gear ring 373 is fixedly arranged on the inner ring of the salvage frame 31, and the axis of the second gear ring 373 is collinear with the axis of the salvage frame 31. The third gear 374 is arranged on the inner ring side of the second gear ring 373, and the third gear 374 and the second gear ring 373 are meshed with each other. The fourth gear 375 is provided with two fourth gears. 75 are respectively arranged on both sides of the third gear 374, and the third gear 374 is respectively meshed with the two fourth gears 375, the inner shell 376 is horizontally arranged inside the salvage frame 31, the inner shell 376 is fixedly arranged at the end of the fourth gear 375, the inner shell 376 is a tubular structure, the electromagnet 378 is fixedly arranged in the middle position of the inner shell 376 and divides the inner shell 376 into two, the magnetic blocks are respectively arranged on both sides of the electromagnet 378, the magnetic blocks are slidably arranged in the inner shell 376, and the outer shell 376 is fixedly arranged in the middle position of the inner shell 376. The outer shell 377 is sleeved on the periphery of the inner shell 376. The outer shell 377 is a tubular structure. An annular cavity is present between the outer shell 377 and the inner shell 376. The annular cavity is communicated with the inner shell 376. A telescopic groove is provided on the peripheral wall of the outer shell 377 in the radial direction. The sweeping rod 371 is slidably arranged in the telescopic groove. The telescopic groove is communicated with the annular cavity. When the electromagnet 378 is energized, the magnetic pole of the electromagnet 378 is different from the magnetic block. The electromagnet 378 can absorb the magnetic block. When the magnetic block is absorbed by the electromagnet 378, the inner shell 376 is The air in 76 is pressed into the annular cavity by the magnetic block, and the air entering the annular cavity pushes the sweeping rod 371 out of the telescopic groove. After the sweeping rod 371 is extended for a period of time, the electromagnet 378 is energized again. At this time, the magnetic pole of the electromagnet 378 is opposite to the magnetic block. The magnetic block moves in the direction away from the electromagnet 378 under the action of repulsive force, and the air in the annular cavity is sucked into the inner shell 376, so that the sweeping rod 371 can be retracted into the telescopic groove, and the hair wrapped around the sweeping block can be filtered out.

[0048] Reference Figure 6-Figure 8 A hair dryer 372 with a downward air outlet is arranged above the salvage frame 31, and the hair dryer 372 can blow away the hair attached to the salvage plate 32.

[0049] The blower 372 blows off the hair attached to the salvaging plate 32 .

[0050] Reference Figure 7 The collecting unit 33 includes a collecting shell 331 and a collecting tube 332.

The collecting shell 331 is provided at the upper portion of the collecting port. The upper opening of the collecting shell 331 is larger than the lower opening of the collecting shell 331. The hair salvaged by the salvage plate 32 falls into the collecting tube 332 through the collecting shell 331.

[0051] When the salvage frame 31 drives the salvage plate 32 to rotate to its upper side, under the action of the blower 372 and the cleaning unit 37, the hair attached to the salvage plate 32 falls into the collecting tube 332 through the collecting shell 331, and the collecting tube 332 runs through the salvage frame 31. The hair that falls into the collecting tube 332 is discharged through the collecting tube 332, avoiding affecting the rotation of the salvage frame 31 when the hair is discharged.

[0052] Reference Figure 4 and Figure 5 : A cleaning unit 333 is provided in the collecting tube 332 and slides along the extending direction of the collecting tube 332. When the cleaning unit 333 slides in the collecting tube 332, it can push out the hair in the collecting tube 332.

When the cleaning plate 3331 slides in the collection tube 332, the winder 3333 for winding the traction ropes 3332 is wound. The winder 3333 on one end of the collecting tube 332 releases the traction rope 3332, and the winder 3333 on the other end retracts the traction rope 3332, so that the cleaning plate 3331 slides in the collecting tube 332. When the cleaning plate 3331 slides in the collecting tube 332, the hair accumulated in the collecting tube 332 is removed. In this way, under the action of the two winders 3333, the cleaning plate 3331 moves back and forth in the collecting tube 332, and the hair accumulated in the collecting tube 332 is discharged from both ends of the collecting tube 332.
