Description

Technical Field

[0001] The present invention relates to the technical field of casing processing, and specifically provides an equipment for scraping the grease on the inner wall of the casing. Background Art

[0002] Casing is a livestock product scraped from the large and small intestines of livestock, mainly used as the outer coat for filling sausages and enema. Casing processing is a traditional food processing technology, mainly using the inner membrane of animal viscera, that is, the intestines, as a food packaging material after a series of processing, especially as the outer layer of meat products such as sausages. Scraping the grease on the inner wall of the casing is an important step in the casing processing process, aiming to ensure the cleanliness and food safety of the casing.

[0003] When processing the casing, it is necessary to remove the excess grease on the outer wall of the casing to improve the greasy feeling during eating. Specifically, during the operation, the worker first lays the casing flat on the processing table, then fits the scraper to the outer wall of the casing and pulls the casing to scrape the grease. However, manual cleaning of the casing is very cumbersome, and workers are prone to fatigue after repeating the operation for a long time. These problems not only increase the labor burden of the workers but also seriously reduce the overall work efficiency.

[0004] After retrieval, a fat intestine degreasing equipment is disclosed in the publication number: CN111758763B. The purpose of the present invention is to provide a fat intestine degreasing equipment that can quickly scrape and is convenient to operate. A fat intestine degreasing equipment includes: a base, on which two first bearing seats are symmetrically arranged; a first rotating shaft is arranged between the two first bearing seats on the same side; drums are arranged on the two first rotating shafts, and a conveyor belt is wound around the two drums; an N-shaped frame is arranged on the base, and the top plate of the N-shaped frame is located directly above the conveyor belt; a scraping mechanism is slidably arranged on the N-shaped frame and can scrape the grease of the fat intestine; a lifting and adjusting mechanism is arranged on the upper part of the N-shaped frame and can drive the scraping mechanism to move. The lifting and adjusting mechanism is connected to the scraping mechanism. The present invention achieves the effects of being able to quickly scrape and being convenient to operate.

[0005] When cleaning the fat intestine through the scraper in the above application, only one side of the fat intestine can be cleaned, and the cleaning effect on the bent areas on both sides of the fat intestine is limited. Summary of the Invention

[0006] Aiming at the deficiencies of the prior art, the present invention provides an equipment for scraping the grease on the inner wall of the casing, which solves the problem of incomplete cleaning of the casing by the scraper.

[0007] To achieve the above object, the present invention is realized through the following technical solutions: An intestinal casing inner wall grease scraping device includes a cleaning table. The inner side wall of the cleaning table is fixedly connected with an inner support rod. One end of the inner support rod is provided with a scraping assembly. The scraping assembly includes two fixed seats located above and below. Opposite sides of the two fixed seats are provided with circular openings.

The side wall of the adjusting block is rotatably connected with a pressing plate through a torsion spring rotating shaft.

[0010] Preferably, on the surface of the cleaning table, two second chutes are respectively provided above and below the inner support rod. A conveying assembly is installed on the outer wall of the inner support rod. The conveying assembly includes two upper and lower connecting sliders and a second tension spring. The two connecting sliders are respectively slidably connected with the two second chutes. The outer wall of the upper connecting slider is fixedly connected with a driving motor. The driving end of the driving motor is fixedly connected with an upper conveying wheel. The outer wall of the lower connecting slider is rotatably connected with a lower conveying wheel through a shaft. The rear side wall of the connecting slider is fixedly connected with a raised layer.

[0011] Preferably, annular conveying grooves are respectively provided on the surfaces of the upper conveying wheel and the lower conveying wheel. An annular rubber pad is fixedly arranged on the surface of the conveying groove. Two groups of toothed rings in meshing connection are respectively fixedly connected to the outer walls of the upper conveying wheel and the lower conveying wheel.

[0012] Preferably, the second tension spring is located inside the upper second chute. The two ends of the second tension spring are respectively fixedly connected with the inner top wall of the second chute and the top wall of the connecting slider.

[0013] Preferably, a cleaning assembly is installed on one side of the fixed seat and above the cleaning table. The cleaning assembly includes two semi-circular shells, a water storage tank, a water pump, and a recycling mechanism. A number of cleaning holes are formed in the inner side wall of the shell. The outer walls of the two shells are respectively fixedly connected to the outer walls of the two fixed seats. A liquid inlet end is fixedly arranged on the side wall of the shell. The liquid inlet of the water pump is connected to the water storage tank through a pipeline, and the liquid outlet of the water pump is connected to the two liquid inlet ends through a three-way pipe.

[0014] Preferably, a semi-circular water baffle is fixedly connected to the side wall of the shell. The recycling mechanism includes a collecting hopper. The bottom end of the collecting hopper is fixedly connected to a return pipe. The other end of the return pipe penetrates through the cleaning table and is connected to the water storage tank, and the outer wall of the return pipe is fixedly connected to the cleaning table. The return pipe includes an upper pipe body, a lower pipe body, and a separation cylinder. An upper chamber is formed inside the separation cylinder. A channel is formed at the center of the upper chamber. A lower chamber is formed outside the channel. A filter ring is fixedly connected to the inner wall of the lower chamber. The lower end of the upper pipe body is connected to the upper chamber, and the upper end of the lower pipe body is connected to the lower chamber.

[0015] Preferably, the bottom of the channel is open. A base is fixedly connected to the outside of the separation cylinder. The top end of the base is fixedly connected to the lower surface of the cleaning table. A cleaning assembly is installed inside the separation cylinder. The cleaning assembly includes a conical sealing head. The sealing head is inserted into the channel. A T-shaped connecting head is fixedly connected to the bottom end of the sealing head. A supporting elastic member is sleeved outside the connecting head. A support frame is slidably connected to the outer wall of the connecting head. The two ends of the support frame are fixedly connected to the inner wall of the base.

[0016] Preferably, the cleaning assembly further includes a second cylinder. The second cylinder is fixedly installed on the upper surface of the separation cylinder. The driving end of the second cylinder penetrates through the separation cylinder and is fixedly connected to a sealing plate. A pulling rope is fixedly connected between the sealing plate and the sealing head. A number of through holes are formed on the surface of the sealing plate. Filter nets are respectively fixedly connected above and below the through holes. A one-way valve is fixedly connected inside the through hole.

[0017] Working principle: The controller controls the first cylinder to extend, so that the two ends of the adjusting frame move to the inclined surfaces of the adjusting blocks. At this time, the scraping plates, the upper conveying wheel, and the lower conveying wheel can be opened, so as to insert the turned casing into the inner support rod. After the casing is placed, the first cylinder contracts, so that the two ends of the adjusting frame move to the outside of the pressing plate, and the two scraping plates are kept closed. Thus, when pulling the casing, the grease on the outer wall of the casing can be comprehensively scraped off by the two groups of scraping plates, realizing the rapid scraping of the grease and improving the cleaning effect of the casing.

[0018] The pressing plate is pushed by the adjusting frame and rotates to the horizontal. At this time, the pressing plate pushes the convex layer to slide, driving the two connecting sliders to move synchronously in opposite directions, so that the two conveying wheels move to the outside of the inner support rod and the rubber pads abut against the casing. The driving motor is controlled by the controller to operate, and the driving motor drives the upper conveying wheel to rotate. When the upper conveying wheel rotates, it drives the casing to move through friction, thus realizing the automatic pulling of the casing.

[0019] The cleaning liquid in the storage tank is pumped into the interior of the housing by the water pump and sprayed out through the cleaning holes, so as to wash away the grease cleaned by the side of the scraper, achieving the effect of automatic cleaning. The recovery mechanism is used to recover the cleaning liquid after cleaning and introduce it into the storage tank for recycling, reducing the waste of water resources. When the cleaning liquid enters the separation cylinder, the grease carried in the cleaning liquid is filtered through the filter ring to prevent the grease from flowing into the storage tank.

[0020] When it is necessary to clean the grease inside the separation cylinder, the cylinder two is controlled by the controller to operate. The cylinder two extends and drives the sealing plate to move downward through the channel, so as to push the accumulated grease in the channel downward. The cleaning liquid below the sealing plate flows upward through the one-way valve through the circulation hole and is squeezed through the cooperation of the sealing plate and the sealing head, so as to reduce the cleaning liquid in the grease. When the grease is compressed to the minimum extent, the sealing plate pushes the sealing head downward until the bottom end of the sealing plate moves to the bottom end of the channel, so that the grease leaves the separation cylinder. Most of the grease will automatically fall off. At the same time, the sealing plate seals the channel and the one-way valve closes the circulation port to prevent the cleaning liquid above from flowing out, realizing the function of automatically cleaning the grease under the non-stop machine state. By placing a collection box under the separation cylinder, the dropped and discharged grease can be collected.

[0021] After the casing completely passes through the scraper, the two ends of the adjusting frame are moved to the inclined surfaces of the adjusting blocks by the operation of the cylinder, so that the scraper, the upper conveying wheel and the lower conveying wheel are opened. Then the casing is pulled back and wound around the winding frame. The winding frame is rotated by the operation of the rotating motor to wind up the casing, so that the casing automatically exits the inner support rod. When the uncleaned end of the casing is about to pass through the scraper, the adjusting frame is controlled to move to the top plane of the adjusting block, realizing the re-closure of the scraper, so as to scrape off the grease at the uncleaned end of the casing, achieving the comprehensive cleaning of the casing and winding up the casing for subsequent transfer to the next processing link.

[0022] The present invention provides a device for scraping grease from the inner wall of the casing. It has the following beneficial effects: 1. In the present invention, the casing is annularly expanded by the inner support rod, so that the scraper is fully in contact with the surface of the casing. Then, when the casing passes through the scraper, the grease on the outer wall of the casing is scraped off by the two groups of scrapers at 360°, realizing the rapid scraping of the grease and improving the cleaning effect of the casing.

[0023] 2. When the upper conveying wheel of the present invention rotates, it drives the casing to move through friction, thereby realizing the automatic pulling of the casing. When the upper conveying wheel rotates, it synchronously drives the lower conveying wheel to rotate, thereby applying a relatively uniform pulling force to the casing and improving the conveying effect of the casing.

[0024] 3. The present invention sprays the cleaning liquid to wash away the grease cleaned on the side of the scraper, achieving the effect of automatic flushing. Moreover, the used cleaning liquid is recycled in the storage water tank after separating the grease, reducing the waste of water resources.

[0025] 4. The present invention extends the second cylinder and performs extrusion through the cooperation of the sealing plate and the sealing head, thereby reducing the cleaning liquid in the grease. Moreover, the sealing plate pushes the accumulated grease in the channel downward and discharges it from the separation cylinder, having the function of automatically cleaning the grease under the non-stop state.

[0028] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to the attached Figure 1 - attached Figure 4, an embodiment of the present invention provides a device for scraping grease from the inner wall of sausage casings, including a cleaning table 1 and a controller. The inner side wall of the cleaning table 1 is fixedly connected by bolts with an inner support rod 2. The inner support rod 2 is hollow inside to reduce weight. One end of the inner support rod 2 is equipped with a scraping assembly 3. The scraping assembly 3 includes two upper and lower fixed seats 31. Opposite sides of the two fixed seats 31 are provided with circular openings. The side walls of the openings are fixedly connected by bolts with semi-circular scraping plates 32. A variety of scraping plates 32 are provided according to different inner diameters of the scraping plates 32 for replacement and use according to different types of sausage casings. Similarly, a variety of inner support rods 2 are provided according to different diameters of the inner support rods 2 for replacement and use according to different types of sausage casings. On the surface of the cleaning table 1, two first chutes 4 are respectively opened above and below the inner support rod 2. The outer wall of the fixed seat 31 is fixedly connected with a support slider 33. One end of the support slider 33 is slidably connected with the first chute 4. The rear side wall of the support slider 33 is fixedly connected with a trapezoidal adjusting block 34. On the opposite sides of the two adjusting blocks 34, a first cylinder 35 is installed. The controller is electrically connected to the first cylinder 35. The outer wall of the first cylinder 35 is fixedly connected with the surface of the cleaning table 1. The driving end of the first cylinder 35 is fixedly connected with a U-shaped adjusting frame 36. When the two ends of the adjusting frame 36 move to the top plane of the adjusting block 34, the other side of the support slider 33 abuts against the side wall of the first chute 4, thereby limiting the support slider 33.

[0030] Specifically, insert the turned sausage casing into the inner support rod 2. The inner support rod 2 expands the sausage casing into a ring shape. Control the first cylinder 35 to extend through the controller, so that the two ends of the adjusting frame 36 move to the inclined surface of the adjusting block 34. At this time, the fixed seat 31 can be pushed to open the scraping plate 32, so that the sausage casing can pass through the scraping plate 32. After the sausage casing passes through the scraping plate 32, the first cylinder 35 contracts, so that the two ends of the adjusting frame 36 move to the top plane of the adjusting block 34, thereby limiting the support slider 33 through the cooperation with the first chute 4, so that the two scraping plates 32 remain closed. By pulling the sausage casing along the inner support rod 2, the grease on the outer wall of the sausage casing can be comprehensively scraped off by the two groups of scraping plates 32, realizing the rapid scraping of grease and improving the cleaning effect of the sausage casing.

[0031] Please refer to the appendix Figure 3 , the diameter of the inner support rod 2 is larger than the diameter of the sausage casing. One end of the inner support rod 2 is fixedly connected with a frustum-shaped guiding head 5.

[0032] Specifically, the diameter of the inner support rod 2 is flexibly adjusted according to different animal types, as long as it can expand the sausage casing and make the sausage casing slightly expand. And the diameter of the scraping plate 32 needs to be larger than the diameter of the inner support rod 2, and the distance between the scraping plate 32 and the inner support rod 2 needs to be slightly smaller than the thickness of the sausage casing. One end of the guiding head 5 has a smaller diameter, which is convenient for guiding the sausage casing to pass through the inner support rod 2.

[0033] Please refer to the appendix Figure 3, the outer wall of the adjusting frame 36 is slidably connected to the side wall of the cleaning table 1. The inner top wall of the upper chute 1 4 is fixedly connected to a first tension spring 37, and the bottom end of the first tension spring 37 is fixedly installed at the top end of the adjacent support slider 33.

[0034] Specifically, when both ends of the adjusting frame 36 move to the inclined surface of the adjusting block 34, the lower support slider 33 automatically slides downward due to its own gravity, and the upper support slider 33 slides upward under the tension of the first tension spring 37, so as to automatically open the scraping plate 32 for casing threading, reducing the manual operation link.

[0035] Please refer to the appendix Figure 5 - appendix Figure 6 , two second chutes 6 are respectively opened above and below the inner support rod 2 on the surface of the cleaning table 1. A conveying assembly 7 is installed on the outer wall of the inner support rod 2. The conveying assembly 7 includes two upper and lower connecting sliders 71 and a second tension spring 76. The two connecting sliders 71 are respectively slidably connected to the two second chutes 6. A driving motor 72 is fixedly connected to the outer wall of the upper connecting slider 71. The controller is electrically connected to the driving motor 72. The driving end of the driving motor 72 is fixedly connected to an upper conveying wheel 73. The outer wall of the lower connecting slider 71 is rotatably connected to a lower conveying wheel 74 through a shaft. Annular conveying grooves 75 are respectively opened on the surfaces of the upper conveying wheel 73 and the lower conveying wheel 74. An annular rubber pad is fixedly arranged on the surface of the conveying groove 75. The rubber pad fits flexibly with the casing to avoid crushing the casing. A convex layer 77 is fixedly connected to the rear side wall of the connecting slider 71. A pressing plate 8 is rotatably connected to the side wall of the adjusting block 34 through a torsion spring rotating shaft. The pressing plate 8 abuts against the connecting convex layer 77 by the torsion of the torsion spring rotating shaft.

[0036] Specifically, when pulling the casing, the two ends of the adjusting frame 36 are moved by the extension of the air cylinder and the pressing plate 8 is pushed to rotate to the horizontal. At this time, the pressing plate 8 pushes the convex layer 77 to slide, driving the two connecting sliders 71 to move synchronously in opposite directions, so that the two conveying wheels move to the outside of the inner support rod 2 and the rubber pads abut against the casing. The controller controls the driving motor 72 to rotate at a constant speed. The driving motor 72 drives the upper conveying wheel 73 to rotate, and when the upper conveying wheel 73 rotates, it drives the casing to move through friction, thus realizing the automatic pulling of the casing.

[0037] Please refer to the appendix Figure 5 , the second tension spring 76 is located inside the upper second chute 6. The two ends of the second tension spring 76 are respectively fixedly connected to the inner top wall of the second chute 6 and the top wall of the connecting slider 71. Two groups of toothed rings 78 which are meshed with each other are respectively fixedly connected to the outer walls of the upper conveying wheel 73 and the lower conveying wheel 74.

[0038] Specifically, when the casing needs to pass through the upper conveying wheel 73 and the lower conveying wheel 74, the lower connecting slider 71 slides downward automatically under its own gravity, and the upper connecting slider 71 slides upward under the tension of the second tension spring 76, so as to automatically open the upper conveying wheel 73 and the lower conveying wheel 74 for casing threading. When the upper conveying wheel 73 and the lower conveying wheel 74 move outside the inner support rod 2, the two toothed rings 78 are automatically engaged. When the upper conveying wheel 73 rotates, it drives the lower conveying wheel 74 to rotate synchronously, so as to apply a relatively uniform tension to the casing and improve the conveying effect of the casing.

[0039] Please refer to the attached Figure 7 - attached Figure 8 , a cleaning assembly 9 is installed on one side of the fixed seat 31 and above the cleaning table 1. The cleaning assembly 9 includes two semi-circular shells 91, a water storage tank 92, a water pump 93 and a recycling mechanism. Brine is added to the water storage tank 92. A number of cleaning holes 97 are provided on the inner side wall of the shell 91. The outer walls of the two shells 91 are respectively fixedly connected to the outer walls of the two fixed seats 31. A liquid inlet end is fixedly arranged on the side wall of the shell 91. The liquid inlet of the water pump 93 is connected to the water storage tank 92 through a pipeline, and the liquid outlet of the water pump 93 is connected to the two liquid inlet ends through a three-way pipe. The controller is electrically connected to the water pump 93.

[0040] Specifically, the shell 91 is connected to the fixed seat 31, so as to open or close synchronously according to the fixed seat 31 for easy casing threading. The cleaning liquid in the water storage tank 92 is pumped into the interior of the shell 91 by the water pump 93 and sprayed out from the cleaning holes 97, so as to wash away the grease cleaned by the side of the scraper 32, achieving the effect of automatic flushing. The recycling mechanism is used to recycle the flushing cleaning liquid and introduce it into the water storage tank 92 for recycling, reducing the waste of water resources.

[0041] Please refer to the attached Figure 8 - attached Figure 9 , a semi-circular water baffle 94 is fixedly connected to the side wall of the shell 91. The recycling mechanism includes a collecting hopper 95. The bottom end of the collecting hopper 95 is fixedly connected to a return pipe 96. The other end of the return pipe 96 penetrates through the cleaning table 1 and is connected to the water storage tank 92, and the outer wall of the return pipe 96 is fixedly connected to the cleaning table 1. The return pipe 96 includes an upper pipe body 961, a lower pipe body 962 and a separation cylinder 963. An upper chamber is provided inside the separation cylinder 963, a channel is provided at the center of the upper chamber, a lower chamber is provided outside the channel, and a filter ring 964 is fixedly connected to the inner wall of the lower chamber. The lower end of the upper pipe body 961 is connected to the upper chamber, and the upper end of the lower pipe body 962 is connected to the lower chamber. The separation cylinder 963 is made of transparent material so that the operator can observe the accumulation amount of grease inside, and thus clean it when the grease accumulates more.

[0042] Specifically, during rinsing, the baffle 94 blocks the sprayed cleaning liquid to prevent the cleaning liquid from splashing and contaminating the surrounding environment, and at the same time helps to collect the cleaning liquid. The cleaning liquid flows into the interior of the collection hopper 95 through the baffle 94 and then flows into the water storage tank 92 through the return pipe 96. When the cleaning liquid passes through the return pipe 96, it flows sequentially through the upper pipe body 961, the separation cylinder 963, and the lower pipe body 962. When the cleaning liquid enters the separation cylinder 963, the grease carried in the cleaning liquid is filtered by the filter ring 964 to prevent the grease from flowing into the water storage tank 92.

[0043] Please refer to the attached Figure 9 - attached Figure 10 , the bottom of the channel is open, and a base 10 is fixedly connected to the outside of the separation cylinder 963. The water storage tank 92 and the water pump 93 are installed at the bottom of the base 10. The top of the base 10 is fixedly connected to the lower surface of the cleaning table 1. A cleaning component 11 is installed inside the separation cylinder 963. The cleaning component 11 includes a conical sealing head 111. The conical sealing head 111 facilitates the better dropping of grease. The sealing head 111 is inserted into the interior of the channel. A sealing ring is fixedly arranged on the outer wall of the sealing head 111 to block the channel. The bottom end of the sealing head 111 is fixedly connected to a T-shaped connector 112. A support elastic member 113 is sleeved outside the connector 112. The support elastic member 113 is made of a fatigue-resistant spring. The outer wall of the connector 112 is slidably connected to a support frame 114. The two ends of the support frame 114 are fixedly connected to the inner wall of the base 10.

[0044] Specifically, the elastic force of the support elastic member 113 elastically supports the sealing head 111 to bear the impact force of the water flow, so that the sealing head 111 is inserted into and stays inside the channel, thereby blocking the channel and making the grease stay inside the separation cylinder 963. The support frame 114 and the connector 112 cooperate to limit the position of the sealing head 111.

[0045] Please refer to the attached Figure 9 - attached Figure 10 , the cleaning component 11 further includes a second cylinder 115. The controller is electrically connected to the second cylinder 115. The second cylinder 115 is fixedly installed on the upper surface of the separation cylinder 963. The driving end of the second cylinder 115 penetrates the separation cylinder 963 and is fixedly connected to a sealing plate 116. A pull rope 117 is fixedly connected between the sealing plate 116 and the sealing head 111. A plurality of through holes 118 are formed on the surface of the sealing plate 116. Filter meshes 119 are fixedly connected above and below the through holes 118 respectively. A one-way valve is fixedly connected inside the through holes 118. A sealing ring is fixedly arranged on the outer wall of the sealing plate 116 to block the channel.

[0046] Specifically, the one-way valve is used to control the one-way upward flow of fluid through the flow port 118. The filter screen 119 is used to filter the cleaning liquid passing through the flow port 118 to prevent grease from entering. When the cylinder two 115 contracts, the sealing plate 116 is driven to be located inside the upper chamber, and the sealing plate 116 is pulled by the pull rope 117, so that the bottom end of the sealing plate 116 is slightly higher than the top end of the support elastic member 113, thereby reducing the pressure on the support elastic member 113 and extending the service life of the support elastic member 113. When it is necessary to clean the grease inside the separation cylinder 963, the controller controls the operation of the cylinder two 115. The cylinder two 115 extends to drive the sealing plate 116 to move downward and pass through the channel, thereby pushing the accumulated grease in the channel downward. The cleaning liquid below the sealing plate 116 then flows upward through the one-way valve through the flow hole, and is squeezed through the cooperation of the sealing plate 116 and the sealing head 111, thereby reducing the cleaning liquid in the grease. When the grease is compressed to the minimum extent, the sealing plate 116 pushes the sealing head 111 downward until the bottom end of the sealing plate 116 moves to the bottom end of the channel, so that the grease leaves the separation cylinder 963, and most of the grease will automatically fall. At the same time, the sealing plate 116 seals the channel, and the one-way valve closes the flow port 118 to prevent the cleaning liquid above from flowing out, realizing the function of automatically cleaning grease in a non-stop state. By placing a collection box below the separation cylinder 963, the dropped and discharged grease can be collected.

[0047] Please refer to the appendix Figure 9 At the bottom end of the sealing head 111, a telescopic cylinder 12 is fixedly connected, and the bottom end of the telescopic cylinder 12 is fixedly connected to the upper surface of the support frame 114.

[0048] Specifically, the telescopic cylinder 12 expands and contracts synchronously with the lifting of the sealing head 111, achieving the effect of isolating the support elastic member 113 and preventing grease from entering the inside of the support elastic member 113.

[0049] Please refer to the appendix Figure 3 - Appendix Figure 4 On the outer wall of the cleaning table 1, a rotating motor 13 is fixedly connected. The controller is electrically connected to the rotating motor 13. The driving end of the rotating motor 13 passes through the cleaning table 1 and is fixedly connected to a winding rack 14.

[0050] Specifically, after the casing completely passes through the scraping plate 32, the two ends of the adjusting frame 36 are moved to the inclined surfaces of the adjusting blocks 34 through the operation of the air cylinder, so that the scraping plate 32, the upper conveying wheel 73 and the lower conveying wheel 74 are opened. Then, the casing is pulled back and wound around the winding frame 14. The rotation motor 13 is controlled to operate by the controller. The rotation of the winding frame 14 is driven by the operation of the rotation motor 13 to wind the casing, so that the casing automatically exits the inner support rod 2. When the uncleaned end of the casing is about to pass through the scraping plate 32, the adjusting frame 36 is controlled to move to the top plane of the adjusting block 34, so as to realize the re-closure of the scraping plate 32, thereby scraping off the grease at the uncleaned end of the casing. While achieving a comprehensive cleaning of the casing, the casing can be wound up for subsequent transfer to the next processing step.

[0051] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
