[0035] like Figures 4 to 6As shown, the flattening device 2 includes a second flattening ring 24, a limit member 27 and a second adjusting member 28. The limit member 27 is arranged inside the second flattening ring 24, and the limit member 27 is connected to the first adjusting member 26 and the second adjusting member 28 outside. The first adjusting member 26 rotates to drive the limit member 27, the second flattening ring 24 and the second adjusting member 28 to rotate. The side of the second flattening ring 24 is provided with a material lowering device 3, and the material lowering device 3 is used to adjust the position of the material. The limit member 27 is lifted and lowered to drive the first adjusting member 26 and the second adjusting member 28 to extend and retract to detect the material height on the conveyor belt 17, and the second flattening ring 24 rotates to flatten the material.

[0036] It should be noted that the deer glue powder is dried using a low-temperature belt vacuum dryer, including a feed tank, the material outlet of the feed tank is connected to the material inlet of the plunger pump, the discharge pipe of the plunger pump passes through the vacuum chamber, a conveyor belt is arranged inside the vacuum chamber, the discharge pipe of the plunger pump is arranged at the feed end of the conveyor belt, the feed end of the conveyor belt is provided with a distributor, the lower side of the conveyor belt is provided with a first heating system, a second heating system, a third heating system and a cooling system from left to right, and a crushing device is arranged below the discharge end of the conveyor belt. The low-temperature belt vacuum dryer has good linkage, compactness, closure, stability and reliability, which simplifies the cumbersome procedures of manual operation of traditional drying equipment such as ovens and drying rooms when drying food and medicines, and reduces pollution links. The rinsed deerskin is added to the extraction tank, 3-5 times the amount of drinking water is added, and 1-3% of the deerskin is added with rice wine for blanching, and the steam pressure is between 0.06 and 0.20 Mpa, keep the temperature at 100-110℃ for 5 minutes until the deerskin appears curled. Then add 3-6 times the amount of drinking water. Boil the blanched deerskin twice with water, add 3-6 times the amount of water for the first time and 2-5 times the amount of water for the second time. Each time, start the timer from when it boils to 100℃, boil for 4-6 hours and 2-5 hours respectively. During the boiling process, the temperature is controlled at 100-110℃ and the steam pressure is maintained at 0.06-0.20 MPa. The extract is pumped into the storage tank through the filter. Three layers of screens are installed from top to bottom in the primary filter tank, with mesh sizes of 60-200 mesh. The screens with mesh sizes of 100 mesh and 120 mesh are installed from top to bottom in the final filter tank. Centrifuge is then used to perform centrifugation. The extract after centrifugation is vacuum concentrated. The first-effect concentration temperature is controlled at 60°C to 80°C, and the first-effect vacuum pressure is ≥0.06 MPa. The second-effect vacuum concentration temperature is controlled at 40°C to 60°C, and the second-effect vacuum pressure is <1.15 g / , concentrated to a relative density of 1.08-1.13 / 50℃, the concentrated glue liquid is transferred to the batching tank in the clean area through a pipeline, and the initial production of deer glue is completed, and then it can be dried. Since the nozzle arranged on the traditional spraying machine 14 is located above the conveyor belt 17, when the deer glue is sprayed from the nozzle on the spraying machine 14, air may appear due to the transportation of the deer glue through the pipeline and the feeding process of the storage tank 15. Therefore, when the deer glue is sprayed on the conveyor belt 17, the thickness is uneven, and the uneven deer glue may have a poor drying effect when it is dried in the drying tank 11. In order to solve this problem, the following improvements are made:

[0037] Add deer glue powder into the storage tank 15, and then transport the deer glue powder to the inside of the drying tank 11 through the spraying machine 14. The jet box 13 sprays hot air into the inside of the drying tank 11, and a plurality of nozzles are arranged below the spraying machine 14, so that the deer glue powder can be sprayed from the nozzles to the top of the conveyor belt 17. Then, the first power column 16 is driven by the motor to rotate, which can drive the conveyor belt 17 to transport the deer glue powder through the inside of the drying tank 11 for drying. When the spraying machine 14 is transporting the deer glue powder, there may be air in the storage tank 15, and when it is transported to the conveyor belt 17, the deer glue powder is transported to the conveyor belt 17. When the deer glue powder is on the conveyor belt 17, the problem of uneven thickness is caused. The side wall of the first protrusion 211 is provided with a material lowering device 3, which can contact with the deer glue powder during transportation, so as to level the height of the deer glue powder. After leveling, there are still thinner places in the deer glue powder. The first adjusting member 26 is driven by a motor to rotate. The rotation of the first adjusting member 26 drives the limit member 27 and the second adjusting member 28 to rotate, thereby driving the multiple second flattening rings 24 to rotate synchronously. The multiple second flattening rings 24 are in contact with the deer glue powder on the conveyor belt 17, and can play the role of squeezing the deer glue powder. When the foot is missing or thin, the second flattening ring 24 can be lowered, and the second flattening ring 24 lowers and drives the material lowering device 3 to lower, so that the collected deer glue powder falls onto the conveyor belt 17, and at the same time, the deer glue powder adhered to the outer wall of the second flattening ring 24 can be removed, and when the second flattening ring 24 is raised or lowered, it can drive the second adjusting member 28 and the first adjusting member 26 to extend and retract, so that when a second flattening ring 24 is raised or lowered, it will not affect the second flattening rings 24 at other positions to extrude the deer glue powder, and the first transmission member 2 5 and the first adjusting member 26 and the limiting member 27 and the second adjusting member 28 are connected to each other, so that even if the second flattening ring 24 rises or falls, it will not affect the rotation of other second flattening rings 24, thereby improving the uniformity of the deer glue powder during drying and preventing the problem of over-drying or under-drying caused by different heights of the deer glue powder. Then, the first flattening roller 23 is used to flatten the deer glue powder again, so that the thickness and compactness of the deer glue powder remain the same, and then the deer glue powder is discharged through the outlet of the drying tank 11 away from the spraying machine 14, thereby completing the drying of the deer glue powder.

[0038] like Figures 3 to 6 As shown, the flattening device 2 includes a first fixed protrusion 22 fixedly mounted on the inner wall of the middle part of the drying tank 11, a first fixed block 21 is fixedly mounted on the end of the first fixed protrusion 22, a second protrusion 212 is fixedly mounted on the outer wall of the first fixed block 21, first rotating columns 214 are rotatably mounted inside both ends of the second protrusion 212, a roller 213 is fixedly mounted on the outer side of the first rotating column 214 at the lower part, a first belt 215 is meshed on the outer wall of the first rotating column 214, a first protrusion 211 is fixedly mounted on the upper part of the second protrusion 212, and a lowering mechanism 214 is arranged on the first protrusion 211. The material device 3 has a first transmission member 25 rotatably mounted on the top side of the second protrusion 212, a first adjusting member 26 rotatably mounted on the first transmission member 25, a limiting member 27 rotatably mounted on the end of the first adjusting member 26, the outside of the limiting member 27 is fixedly mounted to the second flattening ring 24, a second adjusting member 28 is provided on the outside of the limiting member 27 at a mounting position symmetrical to the first adjusting member 26, the end of the first fixed block 21 is located at the upper end of the conveyor belt 17 and a first flattening roller 23 is rotatably mounted thereon, and the first flattening roller 23 has the same height and diameter as the second flattening ring 24.

[0039] It should be noted that when the conveyor belt 17 moves, it engages with the roller 213, thereby driving the roller 213 to rotate. The rotation of the roller 213 drives the first rotating column 214 and the first belt 215 to rotate, and the first belt 215 engages with the upper first rotating column 214, thereby driving the upper first rotating column 214 to rotate, and the upper first rotating column 214 is fixedly connected to the first transmission member 25, thereby driving the first transmission member 25 and the first adjustment member 26 and the second flattening ring 24 to rotate, thereby achieving the purpose of driving multiple second flattening rings 24 to rotate, and the rotation speed of the second flattening ring 24 is the same as the movement speed of the conveyor belt 17, so as to flatten the deer glue powder transported on the conveyor belt 17.

[0040] like Figures 5 and 6 As shown, the first transmission member 25 includes a first rotating block 251 fixedly mounted on the side wall of the upper first rotating column 214, a second rotating block 252 is rotatably mounted inside the first rotating block 251, a first adjusting member 26 is fixedly mounted on the side wall of the second rotating block 252, and the second protrusion 212 rotates to drive the first rotating block 251 and the second rotating block 252 to rotate with the first rotating column 214 as the center.

[0041] It should be noted that the first rotating block 251 is fixedly connected to the side wall of the first rotating column 214, and can drive the first rotating block 251 to rotate when the first rotating column 214 rotates. The rotational connection between the first rotating block 251 and the second rotating block 252 allows the second flattening ring 24 to adapt to different heights and drive multiple second flattening rings 24 to rotate at the same time.

[0042] like Figures 5 and 6 As shown, the first adjusting member 26 includes a first telescopic rod 261 fixedly mounted on the side wall of the second rotating block 252, the outer wall of the first telescopic rod 261 is provided with a first spring 262, the end of the first telescopic rod 261 is fixedly mounted with a third rotating block 263, the inner part of the third rotating block 263 is rotatably mounted with a second rotating column 264, the inner part of the second rotating column 264 is fixedly mounted with a limiting member 27, the first telescopic rod 261 is telescopic to adapt to the height change of the second flattening ring 24, and the first spring 262 makes the second flattening ring 24 concentric with the first rotating column 214 in the normal state.

[0043] It should be noted that the first telescopic rod 261 can enable the second flattening ring 24 to automatically adjust its height when it contacts the deer glue powder on the conveyor belt 17, thereby not affecting the rotation of the second flattening ring 24, and the first spring 262 ensures that the multiple second flattening rings 24 are concentric with the center of the first rotating column 214 under normal circumstances.

[0044] like Figures 5 and 6 As shown, the limiting member 27 includes a first limiting column 273 fixedly installed inside the second rotating column 264, and long fixed blocks 272 are fixedly installed on both ends of the first limiting column 273. A cross fixing plate 271 is fixedly installed on the outer wall of the long fixed block 272, and a second flattening ring 24 is fixedly installed on the outer wall of the cross fixing plate 271. The cross fixing plate 271 is installed in the inner center of the second flattening ring 24. The first limiting column 273 is symmetrically arranged with respect to the cross fixing plate 271, and a second adjusting member 28 is fixedly installed on the outer wall of the first limiting column 273 away from one end of the first adjusting member 26, and the second adjusting member 28 has the same function as the first adjusting member 26.

[0045] It should be noted that when the second rotating column 264 drives the limit member 27 to rotate, if the second flattening ring 24 is lifted or lowered, it can drive the first adjusting member 26 to extend or retract, so that the second rotating column 264 can automatically adjust the angle of engagement with the limit member 27, so that when the second flattening ring 24 is lifted or lowered, the first adjusting member 26 can still drive the second flattening ring 24 to rotate.

[0046] like Figures 4 to 6As shown, the first fixed block 21 is provided with second protrusions 212 at both ends symmetrically with respect to the length of the conveyor belt 17, the length of multiple second flattening rings 24 spliced ​​together is the same as the width of the conveyor belt 17, and the multiple second flattening rings 24 are connected to the limit member 27 through the second adjusting member 28, and the side wall of the upper first rotating column 214 is connected to the limit member 27 through the first transmission member 25 and the first adjusting member 26.

[0047] It should be noted that the length of the multiple second flattening rings 24 is the same as the width of the conveyor belt 17, so that the second flattening rings 24 can completely contact the deer glue powder on the conveyor belt 17, and the connection between the limit member 27 and the second adjusting member 28 is the same as the connection between the first adjusting member 26 and the limit member 27, thereby driving the second flattening ring 24 to rotate, and the two first rotating columns 214 are connected by the first belt 215, thereby driving the second flattening ring 24 to rotate when the roller 213 rotates.

[0048] like Figures 7 and 8 As shown, the material lowering device 3 includes a first fixed plate 31 fixedly installed at the bottom end of the first protrusion 211, a sliding column 33 is rotatably installed inside the first fixed plate 31, the number of the sliding columns 33 is the same as the number of the second flattening rings 24, a square groove 32 is fixedly installed at the top of the sliding column 33, a bottom limiting plate 34 is fixedly installed at the bottom end of the sliding column 33, a second spring 35 is fixedly installed at the top of the bottom limiting plate 34, the second spring 35 is concentric with the sliding column 33, a limiting I-shaped block 36 is fixedly installed on the side wall of the first fixed plate 31 close to the second flattening ring 24 side, a discharge port 37 is fixedly installed on the side of the square groove 32 close to the second flattening ring 24 side, the discharge port 37 is meshed with the limiting I-shaped block 36, and an inclined block 38 is fixedly installed on the top of the square groove 32 close to the second flattening ring 24 side, and the end of the inclined block 38 contacts the outer wall of the second flattening ring 24.

[0049] It should be noted that the deer glue powder on the known conveyor belt 17 moves from the second flattening ring 24 to the first flattening roller 23. Therefore, before the deer glue powder on the conveyor belt 17 contacts the second flattening ring 24, a leveling member 39 is provided on the side wall of the first protrusion 211. The leveling member 39 can highly level the deer glue powder on the conveyor belt 17, and the excess deer glue powder enters the interior of the square groove 32. The second flattening ring 24 contacts the end of the inclined block 38 during the rotation process, so that the outer wall of the second flattening ring 24 is adhered. Deer glue powder is removed. Under normal conditions, the second flattening ring 24 is concentric with the center of the first rotating column 214. When the conveyor belt 17 is carrying deer glue powder, multiple second flattening rings 24 are raised to a certain distance. At this time, multiple second flattening rings 24 are at the same center, and the center of the second flattening ring 24 is above the first rotating column 214. When the deer glue powder on the conveyor belt 17 is missing, the second flattening ring 24 can be driven to descend, and the descent of the second flattening ring 24 drives the inclined block 38 and the square groove 32 to descend. Figure 7 As shown, the part where the limiting I-shaped block 36 meshes with the discharge port 37 is a solid part. The discharge port 37 is in an open state under normal conditions, and the meshing part between the limiting I-shaped block 36 and the discharge port 37 is provided with an opening. When the second flattening ring 24 descends and drives the discharge port 37 to descend, the discharge port 37 engages with the groove provided on the limiting I-shaped block 36, so that the excess deer glue powder on the square groove 32 falls to the bottom of the second flattening ring 24 through the discharge port 37, thereby preventing the deer glue powder on the conveyor belt 17 from being too thin, and at the same time, the excess deer glue powder and the deer glue powder adhering to the outer wall of the second flattening ring 24 can be collected.

[0050] like Figures 7 and 8 As shown, an inclined groove 321 is fixedly installed inside the square groove 32 , the inside of the square groove 32 is connected to the inside of the discharge port 37 , and the length of the inclined block 38 is the same as that of the square groove 32 and the discharge port 37 .

[0051] It should be noted that when the limiting I-shaped block 36 is engaged with the opening inside the discharge port 37, the deer antler powder inside the square groove 32 can fall from the discharge port 37 to below the second flattening ring 24, so that the thickness of the deer antler powder is uniform.

[0052] like Figure 8 As shown, a leveling member 39 is fixedly installed on the side of the first protrusion 211, and the leveling member 39 includes an inclined adjustment plate 392 fixedly installed on the side wall of the first protrusion 211, and third limit blocks 391 are fixedly installed at both ends of the lower part of the inclined adjustment plate 392. A plurality of triangular grooves 393 are arranged at the lower part of the inclined adjustment plate 392.

[0053] It should be noted that a triangular groove 393 is provided on the tilt adjustment plate 392, so that the deer glue powder can pass through from below the triangular groove 393, and the excess deer glue powder passes from above the tilt adjustment plate 392 into the interior of the square groove 32, and the connection method between the tilt adjustment plate 392 and the first protrusion 211 can be a rotating connection, so as to adjust the distance between the triangular groove 393 and the conveyor belt 17 where the deer glue powder is placed.

[0054] A processing technology of a low-temperature vacuum belt dryer for deer glue powder, the method adopts the above-mentioned low-temperature vacuum belt dryer for deer glue powder, and comprises the following steps:

[0055] Step 1, firstly, the deerskin is dehaired and cut, then rice wine is added for blanching, after blanching, it is extracted and concentrated by a centrifuge, and then crystal sugar and soybean oil are added again for glue production, the colloidal deer glue powder is placed in the storage tank 15, then the spraying machine 14 is started, the spraying machine 14 transports the deer glue powder in the storage tank 15 to the inside of the drying tank 11 through a pipeline, and sprays it onto the plurality of conveyor belts 17 through a nozzle, and the jet box 13 is started, and the jet box 13 sprays hot air into the inside of the drying tank 11, completing the preparation work before drying;

[0056] Step 2, when the deer glue powder sprayed from the spraying machine 14 is transported to the direction close to the jet box 13 through the conveyor belt 17, the conveyor belt 17 is meshed with the roller 213, driving the first belt 215 and the second flattening ring 24 and the first flattening roller 23 to rotate. If the deer glue powder on the conveyor belt 17 is unevenly distributed, it can be evenly adjusted by the mixing member 39. When the deer glue powder on the conveyor belt 17 passes through the second flattening ring 24, the second flattening ring 24 is lifted and lowered to drive the first adjustment member 26 and the second adjustment member 28 to extend and retract, and will not affect the rotation of the second flattening ring 24. Multiple second flattening rings 24 detect the thickness of the deer glue powder at different positions on the conveyor belt 17 when it passes. The lifting of the second flattening ring 24 drives the material lowering device 3 to replenish the deer glue powder from below the second flattening ring 24, so that the thickness of the deer glue powder on the conveyor belt 17 is the same, and the paving work is completed;

[0057] Step 3: After the deer glue powder on the conveyor belt 17 passes through the second flattening ring 24, it enters directly below the first flattening roller 23. The first flattening roller 23 can roll and flatten the deer glue powder on the conveyor belt 17, so that the deer glue powder on the conveyor belt 17 has the same thickness and the same compactness, and then is discharged from the outlet on the drying tank 11 away from the spraying machine 14, thereby improving the drying effect.

The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
