Description

Technical Field

[0001] This invention belongs to the field of agricultural and sideline food processing, specifically a scraping and washing device for removing adhesive substances from the surface of sausage casings. Background Technology

[0002] Agricultural and sideline food processing is an industrial sector that uses agricultural, forestry, animal husbandry, and fishery products as raw materials and employs physical, chemical, or biological methods to produce edible or further processed food and raw materials.

[0003] Among the many products, sausage casings are a highly specialized link in the meat processing industry chain. They are made from the small intestines of animals such as pigs, sheep, and cattle, through precise and complex processes such as cleaning, scraping, sorting, salting, or drying.

[0004] In the core process of sausage casing processing, scraping off the surface adhesive is a key step that determines the quality of the sausage casing. This process is commonly known as "intestinal scraping". It aims to completely remove the mucosal layer and part of the muscle layer of the animal's intestinal wall, leaving only the tough and elastic submucosa and serosa as the main body of the sausage casing.

[0005] Traditional sausage casing scraping and washing equipment has relatively simple functions, only able to treat the surface of the sausage casing. However, the adhesive substances on the casing are not only present on the outside, but also on the inner intestinal mucosa, fat, and lymphatic tissue, which are the main targets for treatment. Traditional processes require manual turning of the casing after one side is cleaned and then putting it back into the equipment. This not only requires transferring longer casings out of the equipment and performing a relatively complicated and tedious manual turning, but also adds unnecessary steps to the entire scraping and washing process, greatly reducing work efficiency.

[0006] Therefore, the present invention provides a scraping and washing device for removing adhesive substances from the surface of sausage casings. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0008] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a scraping and washing device for removing adhesive substances from the surface of sausage casings, comprising a cleaning tank, the cleaning tank being composed of a tilting tank and a scraping tank, wherein the inside of the scraping tank is equipped with a height-adjustable friction roller and a central roller, and the outside of the scraping tank is provided with a motor housing for controlling the rotation of the friction roller and the central roller, one of the output ends of the scraping tank being fixedly connected to a rinsing tank, the top of the tilting tank being connected to the rinsing tank, a float for fixing to the end of the sausage casing being provided in the tilting tank, and a drain valve being provided at the bottom of the tilting tank; This setup not only achieves the scraping and washing effect on the surface of the sausage casing, but also completes the time-consuming and laborious process of turning the casing over during the scraping and washing process. At the same time, the inner wall of the casing is initially scraped and washed during the turning process, improving the cleaning effect. The casing can be scraped and washed again directly after turning over, resulting in a completely clean casing. This greatly improves the scraping and washing efficiency and reduces the difficulty of operation. In addition, it can effectively detect quality problems of the casing during the scraping and washing process, thereby ensuring the quality of the casing when it leaves the factory.

[0009] Preferably, the intestine scraping box has two friction rollers, located on the upper and lower sides of the central roller respectively. The intestine scraping box has two output ports and two input ports. One output port is connected to the rinsing box, and one input port is equipped with a return pipe connected to the tilting tank. By setting two friction rollers, two independent scraping and washing areas are formed in the intestine scraping box, which are not connected to each other, ensuring that the liquid level in the lower area is not too high. The two friction rollers rotate in the same direction, but opposite to the rotation direction of the central roller. This allows the intestine casings to be processed simultaneously in the upper and lower areas, further improving work efficiency. It should be noted that the same intestine casing is not being processed simultaneously, but rather two different intestine casings sharing one central roller.

[0010] Preferably, there are two drain valves at the bottom of the inverted tank, distributed on both sides of the inverted tank. A guide pump is fixed to the outside of the drain valve facing the intestine scraping box. The guide pump is connected to the return pipe. With this setting, the effect of circulating treatment of sausage casings is fully realized. The whole process is clear and straightforward. It effectively completes the functions of scraping and washing the front of the sausage casing, turning the sausage casing over, initial scraping and washing the back of the sausage casing, inspecting the sausage casing, and final scraping and washing the back of the sausage casing. It ensures the removal of the adhesive on both sides of the sausage casing. Moreover, the operation is simple and is basically completed by mechanical control, reducing the difficulty of manual operation.

[0011] Preferably, the tilting tank is vertically oriented, with a gap between the rinsing tank and the tilting tank. A docking ring is fixed to the top of the float, and the docking ring is semi-circular. A water injection needle for injecting water is installed on one side of the docking ring. A movable locking valve is provided on the outer side of both the docking ring and the puncture ring. The gap between the rinsing tank and the tilting tank allows the casing to expand sufficiently, while also allowing the float to float. The process of fixing the float to the casing is as follows: by using the movable locking valve, the docking ring and the puncture ring are controlled to move towards the center, wrapping the end of the casing, and then the two are docked and fixed. At the same time, the water injection needle of the puncture ring pierces the casing and injects water to expand the interior. After that, the locking valve is retracted, allowing the casing to tilt normally.

[0012] Preferably, a horizontally arranged electric slide rail is installed on the outer side of the puncture ring, and a flexible connecting pipe is fixedly connected to the moving end of the electric slide rail. A horizontally arranged electric telescopic rod is fixedly connected to the outer side of the docking ring, and a horizontally arranged water injection pipe is fixedly connected to the top of the connecting pipe. Two electric doors are opened on the outer side of the tilting tank for the passage of the float and the puncture ring. When the puncture ring and the docking ring are docked, water and air are injected into the puncture ring through the water injection pipe and the connecting pipe. The locking valve is connected to the connecting pipe and also to the puncture ring for pressure connection, realizing the transmission of water flow. The cooperation between the electric slide rail and the flexible connecting pipe can adapt to the movement process of the locking valve. The electric door is temporarily opened when the float needs to be placed. At this time, the movement of the casing is restricted, so it will not cause the casing to leak out.

[0013] Preferably, an electric telescopic rod parallel to the electric slide rail and electric telescopic rod is also provided below them. The end of the electric telescopic rod is smoothly transitioned. The surface of the float is provided with a connecting groove adapted to it. In order to ensure the stable movement of the float, during the movement, the contact between the lower electric telescopic rod and the connecting groove is used to maintain the connection stability of the float. At the same time, when the locking valve is retracted, the lower electric telescopic rod does not retract immediately, but maintains the state of supporting the float. Meanwhile, the electric door is fully closed. At this time, when the casing above moves downward, it can maintain the centered position of the float, allowing the casing to flip over smoothly. Then, the end of the slender electric telescopic rod is pulled back to ensure that the flipping operation is carried out smoothly.

[0014] Preferably, the float is composed of a hollow ellipse and a solid sphere. The hollow ellipse is vertical and fixed to the top of the solid sphere. The docking ring is fixed to the top of the hollow ellipse. Multiple water injection needles are inclined upwards, and a column is fixed to the bottom of the puncture ring. The float is designed to be heavy at the bottom and light at the top. Under the action of buoyancy, the whole float presents a self-righting state. Even if it loses support, it can always maintain its vertical shape, allowing the casing to be turned over smoothly using the top of the float.

[0015] Preferably, raw material conveying pipes are fixedly connected to both sides of the tilting tank near the bottom. The raw material conveying pipes are L-shaped with the output end pointing vertically upward. A protective shell is installed above the raw material conveying pipes. New floats and puncture rings are continuously transferred to the front end of the locking valve through the raw material conveying pipes to complete the grabbing action. The protective shell is used to protect the driving components and reduce external influences.

[0016] Preferably, the diameter of the central roller is larger than that of the friction roller. The outer sides of the central roller and the friction roller are fixed with protrusions for friction. A divider for segmentation is fixed in the middle of the intestine scraping box, and the surface of the divider has multiple spray holes facing different directions. A motor can be installed in the motor box, and the output direction can be changed through a gear set to achieve the effect that the two friction rollers rotate in the same direction and the central roller rotates in opposite directions. The output speed can also be the same. Since the diameter of the central roller is larger, its angular velocity is also larger, so it can form a speed difference with the friction roller to complete the scraping and washing function. This setting can effectively reduce the control difficulty and investment cost. The divider can not only divide the internal space of the intestine scraping box, but also connect to a water source. By increasing the internal water flow through the spray holes, it can clean the friction roller and the central roller, and also increase the effect of water flow guiding the intestine casing.

[0017] Preferably, it also includes a feeding tray and a discharging tray. The feeding tray is located above the discharging tray. The feeding tray is connected to one of the input ports of the sausage scraping box, and the discharging tray is connected to one of the output ports of the sausage scraping box. A recycling tray is provided below the cleaning box, which allows multiple cleaning boxes to be placed side by side. The feeding tray and the discharging tray are used to place the casings to be processed and the processed casings, thereby improving processing efficiency. The recycling tray can temporarily store the casings flowing out from below the guide pump and at the same time recover excess water from the equipment.

[0018] The beneficial effects of this invention are as follows: 1. The scraping and washing device for removing adhesive substances from the surface of sausage casings according to the present invention, through the arrangement of a scraping box, a turning tank, and a float, not only achieves the scraping and washing effect of adhesive substances on the surface of sausage casings, but also completes the time-consuming and laborious work of turning the sausage casings over in the traditional process during the scraping and washing process. At the same time, the inner wall of the sausage casing is initially scraped and washed during the turning process, which improves the cleaning effect. Furthermore, the turned sausage casings can be scraped and washed again directly to obtain completely clean sausage casings, which greatly improves the scraping and washing efficiency and reduces the difficulty of operation. At the same time, it can also effectively detect quality problems of sausage casings during the scraping and washing process, thereby ensuring the quality of sausage casings leaving the factory.

[0019] 2. The scraping and washing device for removing adhesive substances from the surface of sausage casings according to the present invention forms two independent scraping and washing areas in the sausage scraping box by setting two friction rollers, which are not connected to each other, ensuring that the liquid level in the lower area is not too high. The two friction rollers rotate in the same direction, but opposite to the rotation direction of the central roller. In this way, sausage casings can be processed in both the upper and lower areas at the same time, which further improves the work efficiency. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 8 As shown in the figure, a scraping and washing device for removing adhesive substances from the surface of sausage casings according to an embodiment of the present invention includes a cleaning tank 3, which is composed of a tilting tank 7 and a scraping tank 9. The scraping tank 9 is equipped with a height-adjustable friction roller 24 and a central roller 25. A motor box 6 for controlling the rotation of the friction roller 24 and the central roller 25 is provided on the outside of the scraping tank 9. A rinsing tank 10 is fixedly connected to one of the output ends of the scraping tank 9. The top of the tilting tank 7 is connected to the rinsing tank 10. A float 15 for fixing to the end of the sausage casing is provided in the tilting tank 7. A drain valve 14 is provided at the bottom of the tilting tank 7. The end of the sausage casing to be processed is placed into the upper inlet of the scraping box 9. The top of the scraping box 9 must be connected to a water source to ensure a constant flow of water. This guides the end of the sausage casing to move between the central roller 25 and the friction roller 24. The motor in the motor housing 6 drives the central roller 25 and the friction roller 24 to rotate in opposite directions, transporting the sausage casing towards the rinsing box 10. The different rotational speeds of the central roller 25 and the friction roller 24 cause relative sliding between them during transport. This process continuously rubs against the surface of the sausage casing, thus scraping and cleaning it. Simultaneously, external water can be injected from either side of the central roller 25 and the friction roller 24, or above the friction roller 24, continuously rinsing their surfaces to remove any adhering substances generated during scraping and maintaining their scraping function. It's important to note that the internal water level needs to be maintained at a certain height, generally below the contact surface between the central roller 25 and the friction roller 24, as water weakens the friction effect. This can be achieved by adjusting the friction roller 24... The height allows for clamping and rubbing different types and thicknesses of sausage casings. After the ends of the casings are scraped, they enter the rinsing tank 10 under the flow of water. The rinsing tank 10 has built-in rinsing components to rinse the surface of the casings, further reducing the residue of adhesives on the casing surface. Then, guided by the water flow, the ends of the casings enter the tipping tank 7. At this time, the scraping box 9 pauses the scraping process, while the float 15 is fixed to the end of the casing, and water and some air are injected into the end of the casing. Because the end of the casing is blocked, it will expand after injection. The intestinal casing expands rapidly after swelling, covering the inside of the inverting tank 7, but not tightly adhering to the inner wall. This is because the casing undergoes a 90-degree bend after entering the inverting tank 7, and water flows continuously from top to bottom in the rinsing tank 10. Simultaneously, the friction roller 24 and the center roller 25 have already squeezed the casing, and the water itself has gravity after being injected, so the casing begins to expand at the end. The water flow in the inverting tank 7 continues to move downwards. After being injected with water, the casing moves more easily with the water flow. At this time, the scraping box 9 can continue to scrape and wash, allowing the casing to begin moving forward.The inflated casing moves downwards at one end, but the float 15, with its significant buoyancy, pushes it upwards from the center. Guided by the water flow, the casing continues to flow downwards, causing the entire casing to flip from the end. This results in the casing below the float 15 being in a double-layered overlapping state. Excess casing is discharged through the drain valve 14. Because the injected water and air cannot escape from the casing, they remain above the water surface in the flipping tank 7, allowing the casing to expand and pass through the float 15. Once all the casing has been removed from the scraping box 9, the other end of the casing passes through the float 15 and continues to move along the double-layered casing. Turn the casings completely inside out. After turning them inside out, insert the ends of the casings back into the scraping box 9 for inner layer scraping. At the same time, cut off the part connected to the float 15. This allows for a quick second inner layer scraping process. Additionally, friction protrusions can be provided on the outer surface of the float 15. As the casings pass through, some of the adhesive residue will be removed during the friction process, further improving the cleaning effect. Furthermore, since the water and air are always maintained at the water level in the turning tank 7, if air or water leakage is found in the casings, it indicates that there are leaks. This allows for accurate screening or marking of casings with quality problems in advance. This setup not only achieves the scraping and washing effect on the surface of the sausage casing, but also completes the time-consuming and laborious process of turning the casing over during the scraping and washing process. At the same time, the inner wall of the casing is initially scraped and washed during the turning process, improving the cleaning effect. The casing can be scraped and washed again directly after turning over, resulting in a completely clean casing. This greatly improves the scraping and washing efficiency and reduces the difficulty of operation. In addition, it can effectively detect quality problems of the casing during the scraping and washing process, thereby ensuring the quality of the casing when it leaves the factory.

[0024] The intestine scraping box 9 has two friction rollers 24, which are located on the upper and lower sides of the central roller 25 respectively. The intestine scraping box 9 has two output ports and two input ports. One output port is connected to the rinsing box 10, and one input port is equipped with a return pipe 12 that communicates with the tilting tank 7. During operation, two friction rollers 24 are set up to form two independent scraping and washing areas in the intestine scraping box 9, which are not connected to each other, ensuring that the liquid level in the lower area is not too high. The two friction rollers 24 rotate in the same direction, but opposite to the rotation direction of the central roller 25. This allows the intestine casings to be processed in the upper and lower areas at the same time, further improving work efficiency. It should be noted that the same intestine casing is not being processed at the same time, but rather two different intestine casings sharing one central roller 25.

[0025] There are two drain valves 14 at the bottom of the tilting tank 7, which are distributed on both sides of the tilting tank 7. A guide pump 11 is fixed to the outside of the drain valve 14 facing the direction of the scraping box 9. The guide pump 11 is connected to the return pipe 12. During operation, before securing the casing end, first open the drain valve 14 of the raw material rinsing tank 10 to drain water. At this time, the water flows from top to bottom along the diagonal of the tilting tank 7, so that the downward-moving casing end will move to the middle position of the tilting tank 7, making it easier to secure the float 15 to the casing end. After securing, switch to another drain valve 14 to allow the water and casing to move into the return pipe 12 for temporary storage. After the casing is completely tilted, it is then introduced into the scraping area below the scraping box 9. The guide pump 11 can be a non-contact diaphragm pump, which simply pushes the water flow to allow the water to pass through the return pipe 12. The casing rises upwards and moves into the scraping box 9. A baffle screen is installed in the return pipe 12 to prevent the casing from entering the scraping box 9 before it is fully turned over, although water will flow normally through the baffle screen. An opening exists at the bottom of the guide pump 11, allowing some water to flow under gravity. This opening is initially closed, opening only when the casing reaches the baffle screen. Excess casing will flow out from the bottom of the guide pump 11, but the overlapping ends will remain at the baffle screen position due to water flow. Excess casing can be temporarily stored below the guide pump 11. Once all casings are turned over, the casing ends will gradually unfold along the casing, and... Finally, the casing moves to the baffle position of the return pipe 12. At this point, the baffle is opened. Because the end of the casing is relatively light, it will move into the casing scraping box 9 under the action of water flow. It will be grabbed by the rotating center roller 25 and friction roller 24, and continuously scraped and pushed under the squeezing and rotating action. At the same time, the casings that fall from the guide pump 11 are pulled upwards. Finally, all the casings are transferred out of the casing scraping box 9, completing the complete scraping and washing of the casings. After the flipped end of the casing is grabbed by the center roller 25 and friction roller 24, the connection between the tail of the casing and the float 15 can be cut off. At this time, the casing will be temporarily stored under the guide pump 11 along with the water flow. Once all casings have been dragged out, the next casing can be prepared for processing. A barrier net is also installed in the drain valve 14. Before the previous casing has been completely processed, the new casing will temporarily remain at the bottom of the turning tank 7. The barrier net will be opened after the previous casing has been completely processed. Through this setting, the effect of circulating casing processing is fully realized. The whole process is clear and concise, and it effectively completes the functions of scraping and washing the front of the casing, turning the casing over, initial scraping and washing the back of the casing, inspecting the casing, and finally scraping and washing the back of the casing. This ensures the removal of the adhesive on both sides of the casing. The operation is simple and is basically completed by mechanical control, reducing the difficulty of manual operation.

[0026] The tilting tank 7 is arranged vertically, and there is a gap between the flushing box 10 and the tilting tank 7. The top of the float 15 is fixed with a docking ring 20, which is arranged in a semi-circular shape. A water injection needle 23 for water injection is installed on one side of the docking ring 20. Locking valves 19 that can be moved are provided on the outer sides of both the docking ring 20 and the puncture ring 21. During operation, the gap between the rinsing tank 10 and the tilting tank 7 allows the casing to expand sufficiently, while also allowing the float 15 to float. The process of fixing the float 15 to the casing is as follows: by using the movable locking valve 19, the docking ring 20 and the puncture ring 21 are controlled to move towards the center, wrapping the end of the casing, and then the two are docked and fixed. At the same time, the water injection needle 23 of the puncture ring 21 punctures the casing and injects water to expand the interior. After that, the locking valve 19 is retracted, allowing the casing to be tilted normally.

[0027] A horizontally arranged electric slide rail 16 is installed on the outside of the puncture ring 21. A flexible connecting pipe 17 is fixedly connected to the moving end of the electric slide rail 16. A horizontally arranged electric telescopic rod 18 is fixedly connected to the outside of the docking ring 20. A horizontally arranged water injection pipe 5 is fixedly connected to the top of the connecting pipe 17. Two electric doors for passing through the float 15 and the puncture ring 21 are opened on the outside of the tilting tank 7. During operation, after the puncture ring 21 and the docking ring 20 are docked, water and air are injected into the puncture ring 21 through the water injection pipe 5 and the connecting pipe 17. The locking valve 19 is connected to the connecting pipe 17 and also presses against the puncture ring 21 to achieve water flow transmission. The cooperation between the electric slide rail 16 and the flexible connecting pipe 17 can adapt to the movement of the locking valve 19. The electric door is temporarily opened when the float 15 needs to be placed. At this time, the sausage casing is restricted from moving, so it will not cause the sausage casing to leak out.

[0028] Below the electric slide rail 16 and the electric telescopic rod 18, there is also an electric telescopic rod 18 parallel to it. The end of the electric telescopic rod 18 is smoothly transitioned. The surface of the float 15 is provided with a connecting groove 22 that is adapted to it. During operation, in order to ensure the stable movement of the float 15, the lower electric telescopic rod 18 contacts the connecting groove 22 during the movement to maintain the connection stability of the float 15. At the same time, when the locking valve 19 retracts, the lower electric telescopic rod 18 does not retract immediately, but maintains the state of supporting the float 15. Meanwhile, the electric door is fully closed. At this time, when the casing above moves downward, it can keep the float 15 in the center position, allowing the casing to flip over smoothly. Then, the end of the slender electric telescopic rod 18 is pulled back to ensure the flipping operation is carried out smoothly.

[0029] The float 15 consists of a hollow ellipse and a solid sphere. The hollow ellipse is vertical and fixed to the top of the solid sphere. The docking ring 20 is fixed to the top of the hollow ellipse. Multiple water injection needles 23 are inclined upwards, and a column is fixed to the bottom of the piercing ring 21. During operation, the float 15 is designed to be heavy at the bottom and light at the top. Under the action of buoyancy, it presents an undisturbed state. Even if it loses support, it can always maintain its vertical shape, allowing the casing to be flipped over smoothly using the top of the float 15.

[0030] Raw material conveying pipes 13 are fixedly connected to both sides of the tilting tank 7 at the lower part. The raw material conveying pipes 13 are arranged in an L shape and the output end is vertically upward. A protective shell 8 is installed above the raw material conveying pipes 13. During operation, the new float 15 and puncture ring 21 are continuously transferred to the front end of the locking valve 19 through the raw material conveying pipe 13 to complete the grabbing action. The protective shell 8 is used to protect the drive components and reduce external influences.

[0031] The diameter of the central roller 25 is larger than the diameter of the friction roller 24. The outer sides of the central roller 25 and the friction roller 24 are fixed with friction protrusions. The middle part of the scraping box 9 is fixed with a divider 26 for dividing, and the surface of the divider 26 is provided with multiple spray holes facing different directions. During operation, a motor can be installed in the motor housing 6, and the output direction can be changed through a gear set to achieve the effect that the two friction rollers 24 rotate in the same direction, while the center roller 25 rotates in the opposite direction. The output speed can also be the same. Since the diameter of the center roller 25 is larger and its angular velocity is also larger, it can form a speed difference with the friction rollers 24 to complete the scraping and washing function. This setting can effectively reduce the control difficulty and investment cost. The separator 26 can not only divide the internal space of the intestine scraping box 9, but also connect to a water source. By increasing the internal water flow through the spray holes, it can clean the friction rollers 24 and the center roller 25, and also increase the effect of water flow guiding the intestine casing.

[0032] It also includes a feeding tray 1 and a discharging tray 2. The feeding tray 1 is located above the discharging tray 2. The feeding tray 1 is connected to one of the input ports of the gut scraping box 9. The discharging tray 2 is connected to one of the output ports of the gut scraping box 9. A recycling tray 4 is provided below the cleaning box 3. During operation, multiple cleaning boxes 3 can be placed side by side, and the infeed tray 1 and the discharge tray 2 can be used to place the casings to be processed and the processed casings to improve processing efficiency; the recovery tray 4 can temporarily store the casings flowing out from below the guide pump 11, and at the same time recover excess water from the equipment.

[0033] During operation, the end of the sausage casing to be processed is placed into the upper inlet of the sausage scraping box 9. A water source must be connected to the top of the sausage scraping box 9 to ensure a constant flow of water. This guides the end of the sausage casing to move between the central roller 25 and the friction roller 24. The motor in the motor housing 6 drives the central roller 25 and the friction roller 24 to rotate in opposite directions, transporting the sausage casing towards the rinsing box 10. The different rotational speeds of the central roller 25 and the friction roller 24 cause relative slippage between them during sausage transport. The movement of the friction rollers causes continuous friction against the casing surface, effectively scraping and cleaning it. Simultaneously, external water can be injected from either side of the center roller 25 and friction roller 24, or above the friction roller 24, continuously rinsing their surfaces to remove any adhering substances and maintain their scraping function. It's important to maintain a consistent internal water level, generally below the contact surface between the center roller 25 and friction roller 24, as water weakens the friction effect. This can be achieved by adjusting the friction roller 24... The height of the device 4 allows for clamping and rubbing different types and thicknesses of sausage casings. After the ends of the casings are scraped, they enter the rinsing tank 10 under the flow of water. The rinsing tank 10 has built-in rinsing components that can rinse the surface of the casings, further reducing the residue of adhesives on the casing surface. Then, guided by the water flow, the ends of the casings enter the tipping tank 7. At this time, the scraping box 9 pauses the scraping process, while the float 15 is fixed at the end of the casing, and water and some air are injected into the end of the casing. Because the end of the casing is blocked, it will expand after injection. The expanded sausage casing rapidly increases in volume, covering the inside of the tilting tank 7, but not tightly adhering to the inner wall. This is because the casing undergoes a 90-degree bend after entering the tilting tank 7, and water continuously flows from top to bottom in the rinsing tank 10. Simultaneously, the friction roller 24 and the center roller 25 have already squeezed the casing, and the water itself has gravity after being injected, so the casing begins to expand at the end. The water flow in the tilting tank 7 continues to move downwards. After water is injected, the casing moves more easily with the water flow. At this time, the scraping box 9 can continue to scrape and wash, allowing the casing to begin moving forward.The inflated casing moves downwards at one end, but the float 15, with its significant buoyancy, pushes it upwards from the center. Guided by the water flow, the casing continues to flow downwards, causing the entire casing to flip from the end. This results in the casing below the float 15 being in a double-layered overlapping state. Excess casing is discharged through the drain valve 14. Because the injected water and air cannot escape from the casing, they remain above the water surface in the flipping tank 7, allowing the casing to expand and pass through the float 15. Once all the casing has been removed from the scraping box 9, the other end of the casing passes through the float 15 and continues to move along the double-layered casing. Turn the casings completely inside out. After turning them inside out, insert the ends of the casings back into the scraping box 9 for inner layer scraping. At the same time, cut off the part connected to the float 15. This allows for a quick second inner layer scraping process. Additionally, friction protrusions can be provided on the outer surface of the float 15. As the casings pass through, some of the adhesive residue will be removed during the friction process, further improving the cleaning effect. Furthermore, since the water and air are always maintained at the water level in the turning tank 7, if air or water leakage is found in the casings, it indicates that there are leaks. This allows for accurate screening or marking of casings with quality problems in advance. This setup not only achieves the scraping and washing effect on the surface of the sausage casing, but also completes the time-consuming and laborious process of turning the casing over during the scraping and washing process. At the same time, the inner wall of the casing is initially scraped and washed during the turning process, improving the cleaning effect. The casing can be scraped and washed again directly after turning over, resulting in a completely clean casing. This greatly improves the scraping and washing efficiency and reduces the difficulty of operation. In addition, it can effectively detect quality problems of the casing during the scraping and washing process, thereby ensuring the quality of the casing when it leaves the factory.

[0034] By setting two friction rollers 24 to form two independent scraping and washing areas in the intestine scraping box 9, which are not connected to each other, the liquid level in the lower area is ensured not to be too high. The two friction rollers 24 rotate in the same direction, but opposite to the rotation direction of the central roller 25. This allows the intestine casings to be processed in the upper and lower areas at the same time, further improving work efficiency. It should be noted that the same intestine casing is not being processed at the same time, but rather two different intestine casings sharing one central roller 25.

[0035] Before securing the casing end, first open the drain valve 14 of the raw material rinsing tank 10 to drain the water. At this time, the water flows from top to bottom along the diagonal of the tilting tank 7, so that the downward-moving casing end will move to the middle position of the tilting tank 7, making it easier to secure the float 15 to the casing end. After securing, switch to another drain valve 14 to allow the water and casing to move into the return pipe 12 for temporary storage. After the casing is completely tilted, it is then introduced into the scraping area below the scraping box 9. The guide pump 11 can be a non-contact diaphragm pump, which simply pushes the water flow, allowing the water to climb upward through the return pipe 12. The casing is lifted and moved into the scraping box 9; a baffle screen is installed in the return pipe 12 to prevent the casing from entering the scraping box 9 before it is fully turned over, but the water will flow normally through the baffle screen; there is an opening at the bottom of the guide pump 11, and some water will also flow under the action of gravity. This opening is not open at the beginning, but is opened when the casing moves to the baffle screen; at this time, the excessively long casing will flow out from the bottom of the guide pump 11, but the overlapping ends of the casing will still be located at the baffle screen position under the action of water flow; excess casing can be temporarily stored below the guide pump 11; after all the casings are turned over, the ends of the casings will gradually unfold along the casing and finally Move to the position of the barrier screen on the return pipe 12. At this time, the barrier screen is opened. Since the end of the casing is relatively light, it will move into the casing scraping box 9 under the action of water flow. It will be grabbed by the rotating center roller 25 and friction roller 24, and continuously scraped and pushed under the action of squeezing and rotation. At the same time, it will pull up the casings that fall from the guide pump 11. Finally, all the casings will be transferred out of the casing scraping box 9, completing the complete scraping and washing of the casings. After the flipped end of the casing is grabbed by the center roller 25 and friction roller 24, the connection between the tail of the casing and the float 15 can be cut off. At this time, the casing will be temporarily stored below the guide pump 11 along the water flow. Once all casings have been dragged out, the next casing can be prepared for processing. A barrier net is also installed in the drain valve 14. Before the previous casing has been completely processed, the new casing will temporarily remain at the bottom of the turning tank 7. The barrier net will be opened after the previous casing has been completely processed. Through this setting, the effect of cyclic processing of casings is fully realized. The whole process is clear and straightforward. It effectively completes the functions of scraping and washing the front of the casing, turning the casing over, initial scraping and washing the back of the casing, inspecting the casing, and finally scraping and washing the back of the casing. It ensures the removal of the adhesive on both sides of the casing. The operation is simple and is basically completed by mechanical control, reducing the difficulty of manual operation.

[0036] The gap between the rinsing tank 10 and the turning tank 7 allows the casing to expand sufficiently, while also allowing the float 15 to float. The process of fixing the float 15 to the casing is as follows: by using the movable locking valve 19, the docking ring 20 and the puncture ring 21 are controlled to move towards the center, wrapping the end of the casing, and then the two are docked and fixed. At the same time, the water injection needle 23 of the puncture ring 21 punctures the casing and injects water to expand the interior. After that, the locking valve 19 is retracted, allowing the casing to turn normally.

[0037] After the puncture ring 21 and the docking ring 20 are docked, water and air are injected into the puncture ring 21 through the water injection pipe 5 and the connecting pipe 17. The locking valve 19 is connected to the connecting pipe 17 and also presses against the puncture ring 21 to achieve water flow transmission. The cooperation between the electric slide rail 16 and the flexible connecting pipe 17 can adapt to the movement of the locking valve 19. The electric door is temporarily opened when the float 15 needs to be placed. At this time, the sausage casing is restricted from moving, so it will not cause the sausage casing to leak out.

[0038] To ensure the stable movement of the float 15, during the movement, the lower electric telescopic rod 18 contacts the connecting groove 22 to maintain the connection stability of the float 15. At the same time, when the locking valve 19 retracts, the lower electric telescopic rod 18 does not retract immediately, but maintains the state of supporting the float 15. Meanwhile, the electric door closes to a large extent. At this time, when the casing moves downward, it can keep the float 15 in the center position, allowing the casing to flip over smoothly. Then, the end of the slender electric telescopic rod 18 is pulled back to ensure the flipping operation is carried out smoothly.

[0039] The design of float 15 is bottom-heavy and top-light. Under the action of buoyancy, the whole body presents a roly-poly state. Even if it loses support, it can always maintain its vertical shape, allowing the sausage casing to be flipped over smoothly using the top of float 15.

[0040] The new float 15 and puncture ring 21 are continuously transferred to the front end of the locking valve 19 through the raw material conveying pipe 13 to complete the grabbing action. The protective shell 8 is used to protect the drive components and reduce external influences.

[0041] A motor can be installed in the motor box 6, and the output direction can be changed through a gear set to achieve the effect that the two friction rollers 24 rotate in the same direction and the center roller 25 rotates in opposite directions; the output speed can also be the same. Since the diameter of the center roller 25 is larger and its angular velocity is also larger, it can form a speed difference with the friction rollers 24 to complete the scraping and washing function. This setting can effectively reduce the control difficulty and investment cost; the separator 26 can not only divide the internal space of the intestine scraping box 9, but also connect to a water source to increase the internal water flow through the spray hole. While cleaning the friction rollers 24 and the center roller 25, it can also increase the effect of water flow guiding the intestine casing.

[0042] Multiple cleaning boxes 3 can be placed side by side, and the infeed tray 1 and the discharge tray 2 can be used to place the casings to be processed and the processed casings to improve processing efficiency; the recovery tray 4 can temporarily store the casings flowing out from below the guide pump 11, and at the same time recover excess water from the equipment.
