Description

Technical Field

[0001] The present invention relates to the technical field of casing processing, and particularly to a casing scraping machine for cleaning the inner wall of the casing. Background Art

[0002] With the continuous improvement of global food safety standards and the increasing attention of consumers to healthy diets, the production processes in the meat processing industry are also facing more stringent requirements. As an important material for making sausages and other meat products, the cleanliness of the casing is directly related to the safety and quality of the final products.

[0003] When processing the casing, it is necessary to clean the impurities inside it. The common cleaning work is completed by a casing scraping machine. Workers send one end of the casing between two rotating rollers on the scraping machine. Through the rotation and extrusion of the two rollers, the impurities inside the casing are intercepted on one side of the rollers, and the cleaned casing is output on the other side of the rollers. This cleaning method only uses the external extrusion method to extrude and intercept the impurities, and cannot directly act on the inner wall of the casing to clean the impurities. Therefore, impurity residues will be generated inside the casing, and its cleaning effect is poor. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a casing scraping machine for cleaning the inner wall of the casing. The specific technical solution adopted is as follows: According to the first aspect of the present invention, there is provided a casing scraping machine for cleaning the inner wall of the casing, comprising: A square frame; A spreading structure, arranged inside the square frame and used for spreading the end opening of the casing downward; A first nozzle, located above the spreading structure and used for draining water to the opening position of the spread end of the casing, so that the water acts downward on the end position of the casing and uses the impact effect of the water to make the casing pass downward through its end opening, prompting the casing to turn over; A scraping structure, located below the spreading structure and used for scraping and cleaning the impurities on the outer wall of the turned-over casing; Wherein, when the casing continuously passes through its end opening, the inner wall of the casing is exposed.

[0005] Further, the scraping machine further comprises a bottom table located below the scraping structure. Receiving grooves are provided on both the left and right sides of the top of the bottom table for holding the casing. Side plates are fixed on both the front and rear outer walls of the bottom table. A motor is arranged on the side plate, and the output end of the motor is connected to the outer side wall of the square frame; Wherein, the horizontal axis of the output end of the motor is parallel to the horizontal center line of the square frame and separated from each other on the horizontal plane. Rotating rollers are rotatably arranged on both the left and right sides of the square frame, and the spreading structure is located in the middle of the square frame.

[0006] Furthermore, the scraping structure includes two scraping plates. One scraping plate is fixed on the base table, and a first air cylinder is arranged on the other scraping plate. The fixed end of the first air cylinder is installed on the base table. A support plate is arranged on each scraping plate, and a second spray head is obliquely arranged on the support plate. Wherein, the directions of the two scraping plates are opposite, and the shape of the scraping plate is a V shape with the opening facing downward.

[0007] Furthermore, a top beam is arranged between the two side plates. The top beam slides horizontally on the side plates. Vertical rods are vertically slidably inserted through the front and rear sides of the top beam. A sliding sleeve is slidably sleeved on each vertical rod. A cross beam is connected between the two sliding sleeves, and the first spray head is fixed on the cross beam. Wherein, the bottom of the vertical rod is rotatably installed at the middle position of the side wall of the square frame.

[0008] Furthermore, the top beam and the cross beam are connected by a spring. A sliding column is arranged on the side wall of the sliding sleeve. Guide plates are arranged on the front and rear side walls of the square frame. The shape of the guide plate is triangular, and the sliding column is in sliding contact with the guide plate. Wherein, when the square frame is flipped, the guide plate pushes the sliding column to move in the vertical direction.

[0009] Furthermore, the spreading structure includes two long rods arranged front and back. The two long rods are collinear. The long rods are located inside the square frame. One end of the long rod is fixed on the inner side wall of the square frame. Two right-angle arms are oppositely arranged at the other end of the long rod. One end of the right-angle arm is rotatably connected to the long rod, and a support column is vertically arranged at the other end of the right-angle arm. A moving sleeve is slidably arranged on the long rod. The moving sleeve is rotatably connected to each right-angle arm through a connecting arm. The moving sleeve is connected to the square frame through a second air cylinder.

[0010] Furthermore, a slider is slidably arranged on each right-angle arm. A secondary column is arranged on the slider. The secondary column and the support column cooperate to clamp the casing. The slider and the right-angle arm are connected by an elastic sheet.

[0011] Furthermore, a long plate is arranged on the side wall of each right-angle arm. The length direction of the long plate is along the sliding direction of the slider on the right-angle arm. A hook is rotatably arranged on the side wall of the slider, and the hook slides on the upper surface of the long plate.

[0012] The beneficial effects of the present invention are: By using the method of turning the casing inside out, the inner wall of the casing and the impurities on the inner wall can be directly exposed. Then, the impurities on the outer wall of the casing can be directly cleaned by using the scraping structure, so that the cleaning work can directly act on the inner wall of the casing, which is convenient for thoroughly removing the impurities on the inner wall of the casing, and solves the problem that the traditional sausage scraping machine can only be cleaned by external extrusion. Since the outer wall of the turned-out casing can be directly cleaned, the cleaning speed is faster and the work efficiency is higher; this cleaning method can avoid applying a large extrusion force to the casing and is convenient for protecting the casing.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations. This embodiment is written in a progressive manner.

[0019] As Figures 1 to 6 shown, a sausage scraping machine for cleaning the inner wall of sausage casings according to the present invention includes: a square frame 1; a spreading structure 2, arranged inside the square frame 1 and used for spreading the end opening of the sausage casing downward; a first spray head 3, located above the spreading structure 2 and used for draining water to the opening position of the end of the spread sausage casing, so that the water acts downward on the end position of the sausage casing and uses the impact effect of the water to make the sausage casing pass through its end opening downward, prompting the sausage casing to turn over; a scraping structure 4, located below the spreading structure 2 and used for scraping and cleaning the impurities on the outer wall of the turned-over sausage casing; wherein, when the sausage casing continuously passes through its end opening, the inner wall of the sausage casing is exposed.

[0020] In detail, the first nozzle 3, the square frame 1 and the scraping structure 4 are arranged in sequence from top to bottom, the opening structure 2 is located inside the square frame 1, and the square frame 1 is mainly used to support the opening structure 2. When cleaning the impurities on the inner wall of the casing, one end of the casing is wound around the square frame 1 and installed downward on the opening structure 2. The opening structure 2 opens the end of the casing, so that the casing opening is elastically deformed and its diameter is increased, so as to facilitate the subsequent casing turning work. The first nozzle 3 is used to drain water downward, and the water flow acts on the part of the casing at the opening position of the end of the opened casing, and the casing is opened by the first nozzle 3. Due to the impact force of water and gravity, part of the casing at the opening of the casing passes through its opening and moves downward, and the casing begins to turn over. As the water continues to be discharged, the casing continues to pass through its end opening until the other end of the casing also passes through the opening. The casing turning over is completed, and the inner wall of the casing is exposed. The scraping structure 4 is then used to directly scrape and clean the impurities on the outer surface of the exposed casing, so that the inner wall of the casing can be directly cleaned. When the casing is cleaned, the casing is turned over and restored to its original state in a similar manner.

[0021] By turning the casing over, the inner wall of the casing and the impurities on the inner wall can be directly exposed, and then the scraping structure 4 can be used to directly clean the impurities on the outer wall of the casing, so that the cleaning work can directly act on the inner wall of the casing, which is convenient for completely removing the impurities on the inner wall of the casing, and solves the problem that traditional sausage scrapers can only clean by external extrusion. Since the outer wall of the turned casing can be cleaned directly, the cleaning speed is faster and the work efficiency is higher. This cleaning method can avoid a large extrusion force on the casing and is convenient for protecting the casing.

[0022] Furthermore, the sausage scraper also includes a base 5 located below the scraping structure 4, and storage grooves 6 are provided on the left and right sides of the top of the base 5, and the storage grooves 6 are used to hold sausage casings. Side panels 7 are fixed on the front and rear outer walls of the base 5, and a motor 8 is provided on the side panels 7. The output end of the motor 8 is connected to the outer wall of the square frame 1; The horizontal axis of the output end of the motor 8 is parallel to the horizontal center line of the square frame 1 and separated from each other in the horizontal plane. The left and right sides of the square frame 1 are both rotatably provided with rollers 31, and the support structure 2 is located in the middle of the square frame 1.

[0023] Specifically, when the casing undergoes a turning operation, the inner wall of the casing is exposed. At this time, the casing can be collected through the receiving groove 6 on the left. After the casing is cleaned and restored to its original state, the casing can be collected through the receiving groove 6 on the right. Since the output axis of the motor 8 is separated from the center line of the square frame 1, when the motor 8 drives the square frame 1 to rotate, the expanding structure 2 in the middle of the square frame 1 will flip from one side of the motor 8 to the other side of the motor 8. That is, the two working positions of the expanding structure 2 respectively correspond to the positions above the two receiving grooves 6. The two rollers 31 on the square frame 1 are mainly used for the lapping work during the transportation of the casing, avoiding damage to the casing caused by the square frame 1 when the casing directly contacts the square frame 1 and slides relative to it.

[0024] In the specific operation, the expanding structure 2 is located above the receiving groove 6 on the left. One end of the casing is wound above the square frame 1 and installed on the expanding structure 2. At this time, the water discharged by the first nozzle 3 flips the casing on the expanding structure 2. The flipped casing falls into the receiving groove 6 on the left. After the casing is flipped, the motor 8 drives the square frame 1 to rotate, and the expanding structure 2 flips to above the receiving groove 6 on the right. The first nozzle 3 moves horizontally synchronously with the square frame 1, and the first nozzle 3 discharges water again, and the casing is flipped again. At this time, the scraping structure 4 scrapes and cleans the impurities on the outer surface of the casing in the conveying state. As the casing continues to be conveyed from the receiving groove 6 on the left to the receiving groove 6 on the right, the casing is continuously cleaned. When all the casing enters the receiving groove 6 on the right, the casing cleaning work is completed.

[0025] It should be noted that the scraping structure 4 is located above the first receiving groove 6 among the two receiving grooves 6 for collection work. A drain pipe for discharging the sewage and impurities in the receiving groove 6 is connected to the bottom of each receiving groove 6.

[0026] Furthermore, the scraping structure 4 includes two scraping plates 9. One scraping plate 9 is fixed on the base 5, and a first cylinder 10 is arranged on the other scraping plate 9. The fixed end of the first cylinder 10 is installed on the base 5. A support plate 11 is arranged on each scraping plate 9, and a second nozzle 12 is inclined on the support plate 11; Among them, the directions of the two scraping plates 9 are opposite, and the shape of the scraping plate 9 is a V shape with the opening facing downwards.

[0027] Specifically, when the casing is conveyed from one receiving groove 6 to another receiving groove 6, the first cylinder 10 pushes the upper scraping plate 9 on it to move towards the other scraping plate 9 and makes the two scraping plates 9 contact the outer wall of the casing between them. The scraping plates 9 scrape and clean the impurities on the outer wall of the casing in the conveying state. At the same time, the water discharged by the second nozzle 12 can clean the outer wall of the casing, thereby improving the cleaning effect. By setting the shape of the scraping plate 9 as a V shape with the opening facing downwards, it is convenient for the impurities scraped by the scraping plate 9 to move obliquely along the trajectory of the scraping plate 9 and separate from the casing, thus avoiding the accumulation of impurities at the position of the casing and the scraping plate 9.

[0028] It should be pointed out here that in order to improve the casing conveying effect and avoid the casing slipping due to excessive extrusion pressure or other situations, on the basis of using water flow to turn the casing over, it can be equipped with a conventional conveying structure.

[0029] Furthermore, a top beam 13 is provided between the two side plates 7, and the top beam 13 slides horizontally on the side plates 7, and vertical rods 14 are vertically slidably inserted on both the front and rear sides of the top beam 13, and a sliding sleeve 15 is slidably sleeved on each vertical rod 14, and a cross beam 16 is connected between the two sliding sleeves 15, and the first nozzle 3 is fixed on the cross beam 16; The bottom of the vertical rod 14 is rotatably mounted at the middle position of the side wall of the square frame 1 .

[0030] In detail, when the motor 8 drives the square frame 1 to flip, the square frame 1 will push the vertical rod 14 to move in the vertical direction. At this time, the vertical rod 14 slides vertically on the top beam 13. At the same time, the square frame 1 will use the vertical rod 14 to push the top beam 13 to move in the horizontal direction. The top beam 13 slides laterally on the side plate 7. The vertical rod 14 drives the sliding sleeve 15, the cross beam 16 and the first nozzle 3 to move synchronously laterally, so that the position of the first nozzle 3 and the support structure 2 always corresponds.

[0031] Since the bottom of the first nozzle 3 will be close to the support structure 2 when the casing is turned over, the sliding sleeve 15 can slide on the vertical rod 14 when the square frame 1 is flipped over to raise the height position of the cross beam 16 and the first nozzle 3 to avoid the first nozzle 3 from colliding with the roller 31 on the square frame 1.

[0032] Furthermore, the top beam 13 is connected to the cross beam 16 via a spring 17, a slide post 18 is provided on the side wall of the sliding sleeve 15, and a guide plate 19 is provided on the front and rear side walls of the square frame 1. The guide plate 19 is in a triangular shape, and the slide post 18 is in sliding contact with the guide plate 19; When the square frame 1 is turned over, the guide plate 19 pushes the slide post 18 to move in the vertical direction.

[0033] In detail, the spring 17 provides an elastic thrust for the cross beam 16, so that the slide column 18 maintains contact with the guide plate 19. When the square frame 1 is flipped, the square frame 1 will drive the guide plate 19 to move synchronously. The guide plate 19 uses its upper bevel to push the slide column 18 to move in the vertical direction. The slide column 18 drives the cross beam 16 and the first nozzle 3 to move through the sliding sleeve 15, so that the first nozzle 3 avoids the rotating roller 31. When the square frame 1 is leveled again, the slide column 18 moves to the other bevel of the guide plate 19, and the first nozzle 3 returns to its initial height position.

[0034] Further, the expanding structure 2 includes two long rods 20 distributed front and back. The two long rods 20 are collinear and are located inside the square frame 1. One end of each long rod 20 is fixed to the inner side wall of the square frame 1, and two right-angle arms 21 are oppositely arranged at the other end of the long rod 20. One end of the right-angle arm 21 is rotatably connected to the long rod 20, and a support column 22 is vertically arranged at the other end of the right-angle arm 21. A moving sleeve 23 is slidably arranged on the long rod 20. The moving sleeve 23 is rotatably connected to each right-angle arm 21 through a connecting arm 24, and the moving sleeve 23 is connected to the square frame 1 through a second air cylinder 25.

[0035] Specifically, there are a total of four support columns 22 on the two long rods 20. When the end of the casing is sleeved outside the four support columns 22, the two second air cylinders 25 can be used to respectively pull the two moving sleeves 23 to slide on the two long rods 20. By using the moving sleeve 23 and the connecting arm 24, the right-angle arm 21 is rotated on the long rod 20 and the four support columns 22 are separated from each other. Thus, the four support columns 22 perform the expanding work on the end of the casing.

[0036] Further, a slider 26 is slidably arranged on each right-angle arm 21. A secondary column 27 is arranged on the slider 26. The secondary column 27 cooperates with the support column 22 to clamp the casing, and the slider 26 and the right-angle arm 21 are connected through an elastic piece 28.

[0037] Specifically, when the casing is sleeved on the four support columns 22, the elastic piece 28 can provide elastic force for the secondary column 27 through the slider 26, so that the secondary column 27 and the support column 22 extrude the casing therebetween. Thus, the fixing work of the opening at the end of the casing is realized, and the casing is prevented from slipping off the support column 22.

[0038] Further, a long plate 29 is arranged on the side wall of each right-angle arm 21. The length direction of the long plate 29 is along the sliding direction of the slider 26 on the right-angle arm 21. A hook 30 is rotatably arranged on the side wall of the slider 26, and the hook 30 is slidably located on the upper surface of the long plate 29.

[0039] Specifically, when the casing needs to be sleeved on the support column 22, the worker can push the slider 26 away from the support column 22. At this time, the hook 30 slides on the long plate 29. When the hook 30 slides to the end of the long plate 29, the hook 30 rotates on the slider 26 and hooks on the end of the long plate 29. At this time, the long plate 29 and the hook 30 limit the position of the long plate 29. After the casing is sleeved, the hook 30 can be released, so that the slider 26 moves towards the support column 22 and the secondary column 27 extrudes the casing.

[0040] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
