Description

Technical Field

[0001] This utility model relates to the technical field of sausage casing pulverization, and in particular to a pulverizing device for extracting heparin sodium from sausage casings. Background Technology

[0002] Sodium heparin can interfere with many aspects of the blood clotting process, exhibiting anticoagulant effects both in vivo and in vitro. It can prevent thrombosis and embolism, and treat disseminated intravascular coagulation (DIC) caused by various factors. Chinese utility model patent CN214974533U discloses a pulverizing device for extracting sodium heparin from sausage casings. This pulverizing device uses a belt drive to rotate a reciprocating screw, thereby moving a horizontal plate. When the horizontal plate moves downwards, the processing space for the sausage casings decreases, pressing the upper layers of casings downwards and allowing the blades to cut more tightly packed casings. This reduces the gaps between casings, increases the cutting efficiency of the blades, and improves the extraction rate of sodium heparin.

[0003] However, the aforementioned pulverizing device compresses the casing during operation, causing the casing to press against the blade from top to bottom. This results in significant lateral force on the blade, which can lead to bending or even breakage, thus reducing the reliability of the pulverizing device. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a crushing device for extracting heparin sodium casings that can cut and crush large or complete casings, with less lateral force on the blades and improved reliability.

[0005] This utility model discloses a pulverizing device for extracting heparin sodium casings, comprising a feed hopper, side plates, and a lower conveyor belt. Side plates are provided on both sides of the lower part of the feed hopper. The lower conveyor belt is installed below the feed hopper, with its input end located below the output end of the feed hopper. The output end of the feed hopper is located between the two side plates. The device also includes a drive roller, a driven roller, two push rods, an upper clamping belt, a motor, and multiple blades. The drive roller is rotatably mounted on the upper part of the side plates near the feed hopper. The driven roller is located above the output end of the lower conveyor belt. The fixed ends of the two push rods are rotatably mounted on the two side plates, and the lower ends of the piston rods of the two push rods are rotatably connected to the left and right ends of the driven roller's rotating shaft, respectively. The upper clamping belt is fitted onto the drive roller and the driven roller. The motor is mounted on the side plates, and multiple blades are mounted on the output shaft of the motor. Located outside the driven roller and the output end of the lower conveyor belt; during operation, large or complete sausage casings are placed into the feed hopper, the lower conveyor belt moves and transports the casings backward, while the piston rods of the two push rods extend and push the driven roller downward, causing the upper clamping belt to compact the casings transported on the lower conveyor belt. The drive roller and driven roller drive the upper clamping belt to rotate, causing the upper clamping belt and the lower conveyor belt to transport the compacted casings backward. A motor drives multiple blades to rotate, and the multiple blades pass through the output end of the lower conveyor belt and the outside of the driven roller, so that the multiple blades cut and shred the casings output from the lower conveyor belt and the upper clamping belt. The cut and shredded casings are convenient for further shredding. Compared with the existing technology, it can cut and shred large or complete sausage casings, and the lateral force on the blades is smaller, which will not cause the blades to bend or even break, thus improving reliability.

[0006] Preferably, it also includes a lower support plate, with its two ends connected to two side plates respectively. The lower support plate is located outside the output end of the lower conveyor belt, with its upper end face flush with the lower conveyor belt and its outer end face flush with the cutting edge of the blade. The lower support plate holds the casing, and the casing passes through the lower support plate sequentially when multiple blades cut the casing, so that the lower support plate and the blades work together to cut and crush the casing, reducing casing sagging and pulling, and improving the cutting efficiency of the casing.

[0007] Preferably, it also includes two connecting rods and a pressure plate. The upper ends of the two connecting rods are respectively connected to the piston rods of the two push rods, and the lower ends of the two connecting rods are respectively connected to the two ends of the pressure plate. The pressure plate is located below the driven roller on the outside. The inner end of the pressure plate is in frictional contact with the outer end face of the upper pressing belt, and the outer end of the pressure plate is flush with the cutting edge of the blade. The pressure plate is mounted on the piston rods of the two push rods through the two connecting rods. When the blade cuts the casing, the pressure plate squeezes the casing output from the lower conveyor belt and the upper pressing belt tightly, reducing the stretching of the casing and improving the cutting efficiency of the casing.

[0008] Preferably, the assembly also includes a lower grinding disc, a discharge trough, an upper grinding disc, a gear ring I, a motor II, and a gear I. The lower grinding disc is located below the output end of the lower conveyor belt, with the upper surface of the lower conveyor belt serving as the grinding surface. The discharge trough is installed around the outer side of the lower grinding disc. The upper grinding disc is concentrically mounted on the lower grinding disc, with its lower surface serving as the grinding surface. A through-feed inlet is provided in the middle of the upper grinding disc. Gear ring I is installed on the outer wall of the upper grinding disc. Motor II is installed on the outer side of the discharge trough, and gear I is concentrically mounted on the output shaft of motor II. Gear I meshes with gear ring I. The casings, cut and pulverized by multiple blades, fall into the upper grinding disc and enter the grinding surface between the upper and lower grinding discs through the feed inlet. Motor II drives gear I to rotate, and gear I meshes with gear ring I to drive the upper grinding disc to rotate. This allows the upper and lower grinding discs to work together to further grind and pulverize the casing fragments. The ground and pulverized casing fragments are discharged from the lower grinding disc and enter the discharge trough, achieving further pulverization of the casings and improving the pulverization quality.

[0009] Preferably, it also includes multiple baffles, which are evenly installed on the outer wall of the upper grinding disc and extend into the discharge trough. When the upper grinding disc rotates, it drives the multiple baffles to scrape the casing fragments in the discharge trough, so that the multiple baffles discharge the casing fragments from the discharge trough and improve the discharge efficiency.

[0010] Preferably, it also includes a drive ring and multiple guide plates. The upper end face of the upper grinding disc is funnel-shaped. The drive ring is concentrically mounted on the end face of the upper grinding disc. Multiple guide plates are circumferentially mounted on the inner wall of the drive ring. The lower end faces of the multiple guide plates scrape the upper end face of the upper grinding disc. The drive ring is driven by a drive assembly. When the upper grinding disc rotates, the drive assembly drives the drive ring and multiple guide plates to rotate in opposite directions, so that the multiple guide plates agitate the casing fragments on the funnel-shaped end face of the upper grinding disc and guide the casing fragments to the feed inlet of the upper grinding disc, so that the casing fragments enter the feed inlet of the upper grinding disc efficiently, thereby improving the crushing efficiency.

[0011] Preferably, the drive assembly includes a second gear and a second gear ring. A bracket is mounted on the second motor, and the second gear is rotatably mounted on the bracket. The second gear meshes with the first gear. The second gear ring is mounted on the outer wall of the drive ring, and the second gear ring meshes with the second gear. The second motor drives the first gear to rotate forward, and the first gear meshes with the first gear ring to drive the upper grinding disc to rotate in reverse. At the same time, the first gear meshes with the second gear to drive the second gear to rotate in reverse, and the second gear meshes with the second gear ring to drive the drive ring to rotate forward. This causes the upper grinding disc and the drive ring to rotate in opposite directions, thereby causing the drive ring to drive multiple guide plates to rotate in the opposite direction to the upper grinding disc, so that the multiple guide plates can guide the sausage casing fragments, resulting in a good driving effect.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During operation, large pieces or complete sausage casings are placed into the feed hopper, and the lower conveyor belt moves to transport the casings backward. At the same time, the piston rods of the two push rods extend and push the driven roller downward, so that the upper pressing belt compacts the casings transported on the lower conveyor belt. The drive roller and the driven roller drive the upper pressing belt to rotate, so that the upper pressing belt and the lower conveyor belt transport the compacted casings backward. The motor drives multiple blades to rotate. The height of the multiple blades passes through the output end of the lower conveyor belt and the outside of the driven roller, so that the multiple blades cut and crush the casings output by the lower conveyor belt and the upper pressing belt. The cut and crushed casings are convenient for further crushing. Compared with the prior art, it can cut and crush large pieces or complete sausage casings. The lateral force on the blades is smaller, which will not cause the blades to bend or even break, thus improving reliability. Attached Figure Description

[0020] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example 1

[0021] like Figures 1 to 4 As shown, a pulverizing device for extracting heparin sodium casings includes a feed hopper 1, side plates 2, and a lower conveyor belt 3. Side plates 2 are provided on both sides of the lower part of the feed hopper 1. The lower conveyor belt 3 is installed below the feed hopper 1, with its input end located below the output end of the feed hopper 1. The output end of the feed hopper 1 is located between the two side plates 2. The device also includes a drive roller 4, a driven roller 5, two push rods 6, an upper clamping belt 7, a motor 8, and multiple blades 9. The drive roller 4 is rotatably mounted on the upper part of the side plate 2 near the feed hopper 1. The driven roller 5 is located above the output end of the lower conveyor belt 3. The fixed ends of the two push rods 6 are rotatably mounted on the two side plates 2, respectively. The lower ends of the piston rods of the two push rods 6 are rotatably connected to the left and right ends of the rotating shaft of the driven roller 5, respectively. The upper clamping belt 7 is fitted onto the drive roller 4 and the driven roller 5. The upper part includes a motor 8 mounted on a side plate 2, multiple blades 9 mounted on the output shaft of the motor 8, and multiple blades 9 located outside the output end of the driven roller 5 and the lower conveyor belt 3; it also includes a lower support plate 10, the two ends of which are connected to the two side plates 2 respectively, the lower support plate 10 is located outside the output end of the lower conveyor belt 3, the upper end face of the lower support plate 10 is flush with the lower conveyor belt 3, and the outer end face of the lower support plate 10 is flush with the cutting edge of the blade 9; it also includes two connecting rods 11 and a pressure plate 12, the upper ends of the two connecting rods 11 are connected to the piston rods of the two push rods 6 respectively, the lower ends of the two connecting rods 11 are connected to the two ends of the pressure plate 12 respectively, the pressure plate 12 is located below the driven roller 5 on the outside, the inner end of the pressure plate 12 is in frictional contact with the outer end face of the upper pressing belt 7, and the outer end of the pressure plate 12 is flush with the cutting edge of the blade 9.

[0022] During operation, large or complete sausage casings are placed into the feed hopper 1. The lower conveyor belt 3 moves to transport the casings backward.

The drive roller 4 and the driven roller 5 drive the upper pressing belt 7 to rotate, causing the upper pressing belt 7 and the lower conveyor belt 3 to transport the compacted casings backward. The motor 8 drives multiple blades 9 to rotate. The multiple blades 9 pass through the output end of the lower conveyor belt 3 and the outside of the driven roller 5. The lower support plate 10 supports the casings. When the blade 9 cuts the sausage casing, it passes through the lower support plate 10 in sequence, so that the lower support plate 10 and the blade 9 cooperate to cut and crush the sausage casing. The pressure plate 12 squeezes the sausage casing output from the lower conveyor belt 3 and the upper pressure belt 7 tightly, reducing the stretching of the sausage casing. This allows multiple blades 9 to cut and crush the sausage casing output from the lower conveyor belt 3 and the upper pressure belt 7. The cut and crushed sausage casing is convenient for further crushing. Compared with the existing technology, it can cut and crush large pieces or whole sausage casings. The lateral force on the blades is small, which will not cause the blades to bend or even break, thus improving reliability and cutting efficiency of sausage casing. Example 2

[0023] like Figures 1 to 3 , Figure 5 and Figure 6 As shown, based on Embodiment 1, it further includes a lower grinding disc 13, a discharge chute 14, an upper grinding disc 15, a gear ring 16, a motor 17, and a gear 18. The lower grinding disc 13 is located below the output end of the lower conveyor belt 3, and the upper end surface of the lower conveyor belt 3 is the grinding surface. The discharge chute 14 is installed around the outer side of the lower grinding disc 13. The upper grinding disc 15 is concentrically mounted on the lower grinding disc 13, and the lower end surface of the upper grinding disc 15 is the grinding surface. A through-feed port is provided in the middle of the upper grinding disc 15. The gear ring 16 is installed on the outer wall of the upper grinding disc 15. The motor 17 is installed on the outer side of the discharge chute 14. The output shaft of the motor 17 is concentrically mounted with the gear 18, and the gear 18 meshes with the gear ring 16. It also includes multiple levers 19, multiple... The paddles 19 are evenly installed on the outer wall of the upper grinding disc 15, and multiple paddles 19 extend into the discharge trough 14; it also includes a drive ring 20 and multiple guide plates 21. The upper end face of the upper grinding disc 15 is funnel-shaped. The drive ring 20 is concentrically rotated and installed on the end face of the upper grinding disc 15.

The lower end face of the multiple guide plates 21 scrapes the upper end face of the upper grinding disc 15. The drive ring 20 is driven by a drive assembly; the drive assembly includes a second gear 22 and a second gear ring 23. A bracket is installed on the second motor 17.

The second gear ring 23 meshes with the second gear 22.

[0024] Motor 17 drives gear 18 to rotate forward. Gear 18 meshes with gear ring 16 to drive the upper grinding disc 15 to rotate in reverse. At the same time, gear 18 meshes with gear 22 to drive gear 22 to rotate in reverse. Gear 22 meshes with gear ring 23 to drive the drive ring 20 to rotate forward. This causes the upper grinding disc 15 and the drive ring 20 to rotate in opposite directions. Consequently, the drive ring 20 drives multiple guide plates 21 to rotate in the opposite direction to the upper grinding disc 15. The casings, cut and shredded by multiple blades 9, fall into the upper grinding disc 15. The multiple guide plates 21 agitate the funnel-shaped end face of the upper grinding disc 15. The casing fragments are guided to the feed inlet of the upper grinding disc 15, allowing them to enter the feed inlet of the upper grinding disc 15 efficiently. The casing fragments enter between the grinding surfaces of the upper grinding disc 15 and the lower grinding disc 13 through the feed inlet. The upper grinding disc 15 and the lower grinding disc 13 work together to further grind and pulverize the casing fragments. The ground and pulverized casing fragments are discharged from the lower grinding disc 13 and enter the discharge trough 14. Multiple baffles 19 discharge the casing fragments from the discharge trough 14, achieving further pulverization of the casings.

The casings are crushed and then cut into powder by multiple blades 9, falling into the upper grinding disc 15. Under the agitation of multiple guide plates 21, they enter the grinding surface between the upper grinding disc 15 and the lower grinding disc 13 through the feed inlet. The motor 2 17 drives the gear 18 to rotate, and the gear 18 meshes with the gear ring 16 to drive the upper grinding disc 15 to rotate, so that the upper grinding disc 15 and the lower grinding disc 13 cooperate to further grind and crush the casing fragments. The ground and crushed casing fragments are discharged from the lower grinding disc 13 and enter the discharge trough 14.
