Description

Technical Field

[0001] This invention relates to the field of sausage casing processing technology, specifically to an automated sausage casing processing production equipment. Background Technology

[0002] Sausage casings are livestock products made from the small and large intestines of domestic animals through physical scraping, cleaning, and salting processes. They are mainly used as natural outer packaging materials for meat products such as sausages and stuffed sausages. Based on the animal species, natural sausage casings can be divided into pig casings, sheep casings, and beef casings. They have advantages such as good toughness, high permeability, edibility, and adaptability to meat processing techniques such as steaming, boiling, and smoking. The core of sausage casing processing lies in effectively removing the mucous membrane layer and oily deposits from the inner wall of the intestine while preserving a complete and uniform fibrous layer. This process requires extremely high precision and stability from the processing equipment. It is essential to ensure scraping efficiency while avoiding casing rupture and perforation caused by improper operation, which directly affects the yield and grade of the finished sausage casings.

[0003] With the widespread application of automated processing technology in the field of livestock by-product processing, automated sausage casing processing equipment has been widely used. Existing equipment typically integrates automatic feeding, conveying, scraping, and winding processes to improve processing efficiency and reduce manual intervention. Taking the patent application number 202211289972.8, "An Automated Sausage Casing Processing Equipment," as an example, it discloses a technical solution including a feeding roller, a transfer roller, a drive shaft, a scraping device, and a sensor control system. By coordinating the transfer roller and the feeding roller to continuously feed the intestines, and utilizing a scraping mechanism to complete the mucosal removal, the main processes of sausage casing processing are automated.

[0004] However, existing automated sausage casing processing equipment still has significant technical deficiencies in the dynamic matching of the intestine conveying and scraping mechanisms. Currently, the mainstream feeding method mostly uses a conveyor wheel to compress the intestine and relies on friction to achieve axial propulsion. However, the contact area between the conveyor wheel and the intestine is a localized band, with limited force coverage, making it difficult to ensure uniform force distribution throughout the intestine and maintain precise, uniform forward movement. Especially when the intestine enters the scraping mechanism, to ensure effective scraping, the inlet of the scraping mechanism usually needs to be pre-expanded to a certain diameter. If the intestinal forward movement speed fluctuates or the local force is uneven, instantaneous tensile stress concentration can easily occur at the expanded end, leading to overload of the intestinal tissue in the area contacting the scraper, resulting in tensile deformation or even tearing. These problems are particularly prominent when processing thin-walled sausage casings or raw sausages with high water content. For example, the patent application number 202211289972.8, "An Automated Sausage Casing Processing Equipment", uses a feeding method with a transfer roller and a feeding roller. Although it is equipped with a backstop roller and a position sensor, the local pressing and traction mode of the transfer roller on the intestine has not fundamentally improved the defect of uneven force distribution. During the intestine support and scraping stage, there is also a situation where the sausage casing is damaged due to local pulling, which restricts the further improvement of the equipment's processing quality and applicability. Summary of the Invention

[0005] In existing automated sausage casing processing, the transmission of intestines to the scraping mechanism often uses a transfer wheel. However, the force exerted by the transfer wheel on the intestine has a limited coverage area, resulting in inaccurate and uneven forward movement of the intestine. Especially when the intestine enters the scraping mechanism, the scraping mechanism requires the intestine to support it, which can easily cause localized straining and damage to the intestine in contact with the scraping mechanism. To achieve the above objectives, this invention provides the following technical solution:

[0006] An automated sausage casing processing production device includes a processing box mounted on a base plate, a storage box installed on the side of the processing box, and multiple automated sausage casing processing components installed inside the processing box. Each automated sausage casing processing component includes a sausage scraper and two automated transmission components distributed at both ends of the sausage scraper. The automated transmission components include:

[0007] An external transmission component is assembled inside the processing box; the external transmission component acts from outside the intestine and pushes the intestine forward;

[0008] An internal transmission component is inserted inside an external transmission component, with a material transfer gap reserved between them; the internal transmission component acts from inside the intestine and pushes the intestine forward.

[0009] The external and internal drive components simultaneously clamp the intestine from both the inside and outside, providing comprehensive clamping force and pushing it forward. On one side of the scraping component, the automated casing processing component activates the external and internal drive components to simultaneously clamp the intestine from both the inside and outside, pushing it towards the scraping component. On the other side of the scraping component, the automated casing processing component activates the external and internal drive components to simultaneously clamp the intestine from both the inside and outside, pulling it forward from the scraping component. This provides comprehensive clamping force to the intestine and allows it to move forward precisely and evenly in all directions, ensuring that the intestine is subjected to uniform force and passes smoothly through the scraping component.

[0010] Preferably, the external transmission component includes:

[0011] The crossbeam is assembled inside the machining box;

[0012] Multiple unit external transmission components are distributed at equal intervals along the crossbeam; the unit external transmission components are mounted on the crossbeam.

[0013] Preferably, the unit external transmission component includes:

[0014] The retaining ring is fixed to the crossbeam by a connecting rod;

[0015] The first electric telescopic rod is fixed to the fixed ring;

[0016] A positioning plate is fixed to the end of the first electric telescopic rod away from the fixing ring.

[0017] An outer support cylinder is fixed to the positioning plate; the columnar centerline of the outer support cylinder and the columnar centerline of the fixing ring are on the same straight line.

[0018] Preferably, the unit external transmission component further includes a first airbag gasket, which is laid on the inner wall of the outer support cylinder; the first airbag gasket can be inflated and deflated.

[0019] Preferably, the internal transmission component includes multiple unit internal transmission components, which are arranged in a straight line and are detachably installed inside the processing box; each unit internal transmission component includes a positioning guide structure and an internal moving transmission head, which are assembled together and are located on the same straight line.

[0020] Preferably, the positioning guide structure includes:

[0021] Fixed column;

[0022] One end of the positioning guide tube is attached to the fixed post; the other end of the positioning guide tube is fixed to the fixed post of another positioning guide structure of the adjacent unit's internal transmission component.

[0023] An inner cavity is formed inside the positioning guide tube; the inner cavity is distributed along the main body of the positioning guide tube;

[0024] Multiple guide grooves are formed on the positioning guide tube and are distributed in a ring array on the positioning guide tube; the guide grooves will connect to the inner cavity.

[0025] Preferably, the internal moving transmission head includes:

[0026] The second electric telescopic rod has one end fixed inside the inner cavity and is distributed along the inner cavity with the main body; a gap is reserved between the main body of the second electric telescopic rod and the inner cavity;

[0027] Multiple fixing plates are arranged in a one-to-one correspondence with multiple guide grooves; the fixing plates are slidably assembled inside the guide grooves.

[0028] The inner support cylinder is movably sleeved on the positioning guide tube and can move along the positioning guide tube.

[0029] Preferably, the inner moving transmission head further includes a second airbag gasket, which is sleeved on the outside of the inner support cylinder and can be inflated and deflated.

[0030] Preferably, the intestinal scraping component includes an outer locking cylinder structure and an inner scraping cylinder. The outer locking cylinder structure is sleeved outside the inner scraping cylinder, and the inner scraping cylinder is located on the columnar centerline of the outer locking cylinder structure. The inner scraping cylinder is fixed on the inner transmission component and is linearly distributed with the inner transmission component. A storage cavity is opened inside the inner scraping cylinder, and multiple scraping grooves are opened on the outer surface of the inner scraping cylinder. The scraping grooves are connected to the storage cavity through a guide hole. A drain port connected to the storage cavity is provided on the inner scraping cylinder. An oblique scraper is provided at the outer opening of the scraping groove.

[0031] Preferably, the outer locking cylinder structure includes:

[0032] External locking cylinder;

[0033] The positioning ring is sleeved and fixed to the outside of the outer locking cylinder;

[0034] A gas regulator is fixed on the positioning ring; the gas regulator is used for assembly inside the processing box;

[0035] The third airbag ring is laid on the inner wall of the outer locking cylinder; the third airbag ring is connected to a gas regulator, which can inflate and deflate the third airbag ring.

[0036] The core of an automated sausage casing processing equipment lies in the innovative structural design and coordinated operation of automated transmission components (as the transmission mechanism) and scraping components (as the scraping mechanism), which systematically solves the technical problems of uneven intestinal force and incomplete removal of foreign matter in traditional equipment. Specifically, automated transmission components are symmetrically arranged on both sides of the scraping component, and each automated transmission component includes an external transmission component and an internal transmission component. During operation, the automated transmission component on one side of the scraping component activates the external and internal transmission components, which simultaneously clamp the intestine from the outside and inside of the intestine and push it towards the scraping component. Meanwhile, the processing component on the other side of the scraping component clamps the intestine in the same way and pulls it outward from the scraping component, forming a two-way coordinated drive mode of "push forward and pull backward". This provides the intestine with a continuous and stable clamping force covering the entire circumference, enabling the intestine to move forward accurately and evenly in all directions, and completely avoiding the tearing damage caused by localized force concentration.

[0037] To achieve precise control of the clamping and driving mechanism, this invention uses multiple external transmission units and multiple internal transmission units as execution units. Taking four units as an example: When the intestine enters the working area between the external and internal transmission units, the first and third external transmission units activate simultaneously—inflating the first airbag pad to expand inwards and gently conform to the intestine from the outside; simultaneously, the first and third internal transmission units activate simultaneously—inflating the second airbag pad to expand outwards and support the intestine from the inside. After inflation, the first electric telescopic rod of the external transmission unit extends, driving the outer support cylinder and the first airbag pad to move axially; the second electric telescopic rod of the internal transmission unit extends simultaneously, driving the inner support cylinder and the second airbag pad to move axially. Thus, the first and third units form two stable clamping points, creating a traction unit that smoothly pushes the intestine forward. At the same time, the second and fourth external transmission components and internal transmission components of the unit complete the deflation and reset of the airbags, and immediately receive the intestine delivered by the previous traction unit, then inflate, clamp, and drive; in this way, the odd-numbered and even-numbered external transmission components and internal transmission components of the unit alternately inflate, extend, retract, and reset, forming a continuous alternating traction flow, ensuring that the intestine is always evenly supported by multiple sets of clamping points, achieving precise feeding without pulses or slippage, and laying a stable and constant tension material foundation for the subsequent intestinal scraping process.

[0038] In the intestinal scraping process, this invention overcomes the limitation of traditional scrapers that can only act on the outer surface of the intestine. Traditional equipment (such as the scheme disclosed in the patent application number.) places the scraper outside the intestine. Due to the significant elasticity of the intestine, when internal foreign objects (such as residual mucosa and fat clumps) pass through the scraper with the deformation of the intestine, they are very likely to "dodge" and avoid the blade, resulting in incomplete scraping and repeated processing. This invention adopts a closed intestinal scraping assembly composed of an outer locking cylinder structure and an inner scraping cylinder: when the intestine is evenly fed into the annular gap between the outer locking cylinder and the inner scraping cylinder by the transmission system, the third air bladder pad periodically expands according to the control system command, pressing the intestinal wall evenly against the outer surface of the inner scraping cylinder; the surface of the inner scraping cylinder has multiple scraping grooves distributed circumferentially and axially, and oblique scrapers are embedded in the grooves; under the action of air pressure, the intestine is squeezed into the scraping grooves, and the internal foreign objects are forced into the grooves to make forced cutting contact with the oblique scrapers, thereby realizing the all-round and thorough scraping of foreign objects on the inner wall of the intestine.

[0039] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0040] 1. The automated casing processing unit on one side of the intestinal scraper activates the external and internal drive components to simultaneously clamp the intestine from both the inside and outside of the intestine and push it towards the scraper; the automated casing processing unit on the other side of the scraper activates the external and internal drive components to simultaneously clamp the intestine from both the inside and outside of the intestine and pull the intestine to move from the scraper, so as to provide full clamping force to the intestine and move it forward in all directions with precision and uniformity, so that the intestine is subjected to uniform force and passes smoothly through the scraper.

[0041] 2. Taking an example where there are four external and four internal transmission units, after the intestine enters between the external and internal transmission units, the first and third external transmission units are simultaneously activated from the outside of the intestine, while the first and third internal transmission units are simultaneously activated from the inside of the intestine. That is, the external transmission unit inflates the first airbag cushion, causing it to expand inwards, thus completing the action of the external transmission unit on the intestine from the outside; the internal transmission unit inflates the second airbag cushion, causing it to expand outwards, thus completing the action of the internal transmission unit on the intestine from the inside. The external transmission component activates the first electric telescopic rod, which synchronously moves the outer support cylinder and the first airbag pad through its extension and retraction. The internal transmission component activates the second electric telescopic rod, which synchronously moves the inner support cylinder and the second airbag pad through its extension and retraction. This creates a clamping point between the first external transmission component and the first internal transmission component, and another clamping point between the third external transmission component and the third internal transmission component. This ensures a stable traction unit between the two clamping points, which is beneficial for the intestine to be evenly stressed and move forward accurately and evenly in all directions, and to pass smoothly through the intestinal scraping component.

[0042] During this process, the second and fourth external transmission units, which reset from the outside, and the second and fourth internal transmission units, which reset from the inside, receive the intestines that are synchronously pulled in by the first and third external transmission units and the first and third internal transmission units. This allows the first and third external and internal transmission units to pull the intestines synchronously with the second and fourth external and internal transmission units. In this way, the odd-numbered and even-numbered external and internal transmission units alternately inflate, expand, and reset, forming a continuous alternating traction flow. This ensures that the intestines are always evenly supported by multiple sets of clamping points, achieving precise feeding without pulses or slippage, and laying a stable and constant tension material foundation for the subsequent intestinal scraping process.

[0043] 3. Traditional intestinal scrapers are all external. When the intestine passes through the scraper, due to the elasticity of the intestine, foreign objects inside the intestine can easily evade the scraper as the intestine deforms (for example, the "scraper" disclosed in the patent application number 202211289972.8, an automated sausage casing processing production equipment, is set externally, and foreign objects will evade the "scraper" when the intestine passes through it). Therefore, in this invention, after the intestine enters between the outer locking cylinder structure and the inner scraping cylinder, the third airbag cushion periodically expands and squeezes the intestine onto multiple scraping grooves on the outer surface of the inner scraping cylinder, realizing that foreign objects inside the intestine can enter multiple scraping grooves from all directions and be scraped off by the oblique scraper; the scraping efficiency of foreign objects inside the intestine is high and the effect is good.

[0044] 4. The transmission system adopts a clamping method with alternating traction on both the inner and outer sides, which not only makes the intestine move at a uniform speed and in a precise position, but more importantly, it has already spread the intestine evenly to the preset diameter in the circumference before it enters the scraping station. This "pre-spreading" state is perfectly matched with the periodic expansion and squeezing action of the outer locking cylinder. The automated transmission component, as the transmission mechanism, continuously feeds the intestine under stable tension. The air bladder expansion and squeezing of the scraping component, as the scraping mechanism, no longer needs to overcome the resistance caused by local accumulation or relaxation of the intestine. The expansion force can be completely converted into effective scraping work, thus improving the scraping efficiency.

[0045] 5. The odd-numbered and even-numbered external and internal transmission components alternately inflate, extend, and reset, forming a continuous alternating traction. Although not rigidly synchronized with the rhythm of the periodic expansion of the airbag, it naturally forms an optimal rhythm of "traction-compression-scraping-reset" during continuous operation. This allows foreign objects inside the intestine to be repeatedly exposed to the scraper path during dynamic compression, improving the cleanliness of the scraping and eliminating the need for secondary manual inspection.

[0065] The technical solution of the present invention will be further described in detail below with reference to specific embodiments. In the description of the present invention, unless otherwise stated, "a plurality of" means two or more.

[0066] In one embodiment of the present invention, please refer to Figures 1-3 An automated sausage casing processing production equipment includes a processing box 3 mounted on a base plate 2. A storage box 1 is installed on the side of the processing box 3. Multiple automated sausage casing processing parts 4 are installed inside the processing box 3. The automated sausage casing processing parts 4 include a sausage scraping part 6 and two automated transmission parts 5 distributed at both ends of the sausage scraping part 6.

[0067] The parts other than the automated sausage casing processing part 4 are not described because they are all existing technologies and can be purchased directly on the market or assembled by purchasing parts, etc. Whether they are disclosed or not does not affect the automated sausage casing processing part 4 that is to be protected, so they will not be described in detail here.

[0068] Automated transmission component 5 includes:

[0069] An external transmission component 51 is assembled inside the processing box 3; the external transmission component 51 acts from outside the intestine and pushes the intestine forward;

[0070] The inner transmission component 52 is inserted inside the outer transmission component 51, and a material transmission gap is reserved between them; the inner transmission component 52 acts from inside the intestine and pushes the intestine forward.

[0071] Among them, the external transmission component 51 and the internal transmission component 52 simultaneously clamp the intestine from both the inside and outside sides of the intestine, providing a full clamping force to the intestine and then pushing it forward.

[0072] Therefore, in existing automated sausage casing processing, the method of transmitting the intestine to the scraping mechanism mostly uses a transfer wheel. However, the force exerted by the transfer wheel on the intestine has a limited coverage area, and the intestine cannot move forward accurately and evenly. In particular, when the intestine enters the scraping mechanism, the scraping mechanism requires the intestine to support it, which can easily cause localized damage to the intestine in contact with the scraping mechanism due to tensile stress. This application can achieve the following:

[0073] The automated casing processing unit 4 on one side of the intestinal scraping component 6 activates the external transmission component 51 and the internal transmission component 52 to simultaneously clamp the intestine from both the inside and outside of the intestine and push it towards the intestinal scraping component 6; the automated casing processing unit 4 on the other side of the intestinal scraping component 6 activates the external transmission component 51 and the internal transmission component 52 to simultaneously clamp the intestine from both the inside and outside of the intestine and pull the intestine to move from the intestinal scraping component 6, so as to provide the intestine with full clamping force and then move it forward in all directions with precision and uniformity, so that the intestine is subjected to uniform force and passes smoothly through the intestinal scraping component 6.

[0074] In another embodiment of the present invention, please refer to Figures 3-5 The external transmission component 51 includes:

[0075] Crossbeam 511 is assembled inside machining box 3;

[0076] Multiple unit external transmission components 512 are distributed at equal intervals along the crossbeam 511; the unit external transmission components 512 are mounted on the crossbeam 511.

[0077] For further details, please refer to Figure 5 The unit external transmission component 512 includes:

[0078] The fixing ring 513 is fixed to the crossbeam 511 by the connecting rod 514;

[0079] The first electric telescopic rod 515 is fixed on the fixing ring 513;

[0080] Positioning plate 516 is fixed to the end of the first electric telescopic rod 515 away from the fixing ring 513;

[0081] The outer support cylinder 517 is fixed on the positioning plate 516; the column center line of the outer support cylinder 517 and the column center line of the fixing ring 513 are on the same straight line.

[0082] Please see Figure 5 The unit external transmission component 512 also includes a first airbag pad 518, which is laid on the inner wall of the outer support cylinder 517; the first airbag pad 518 can be inflated and deflated.

[0083] In another embodiment of the present invention, please refer to Figure 3 , Figure 6 and Figure 7 The internal transmission component 52 includes multiple internal transmission components 521 (each internal transmission component 521 corresponds to a external transmission component 512), the multiple internal transmission components 521 are arranged in a straight line and are detachably installed inside the processing box 3; each internal transmission component 521 includes a positioning guide structure 522 and an internal moving transmission head 523, the positioning guide structure 522 and the internal moving transmission head 523 are assembled together and are on the same straight line.

[0084] Meanwhile, the specific number of multiple internal transmission components 521 can be two, four, six, eight, etc., and there is no limit to the exact number, as long as they can act alternately from inside the intestine and push the intestine forward. Here, it is preferred to use four internal transmission components 521.

[0085] Please see Figures 6-8 The positioning and guiding structure 522 includes:

[0086] Fixed column 5221;

[0087] The positioning guide tube 5222 is attached to the fixed post 5221 at one end; the other end of the positioning guide tube 5222 is fixed to the fixed post 5221 of another positioning guide structure 522 of the adjacent unit internal transmission component 521.

[0088] An inner cavity 5224 is formed inside the positioning guide tube 5222; the inner cavity 5224 is distributed along the main body of the positioning guide tube 5222;

[0089] Multiple guide grooves 5223 are all formed on the positioning guide tube 5222 and are distributed in a ring array on the positioning guide tube 5222; the guide grooves 5223 will connect to the inner cavity 5224.

[0090] Please see Figure 7 , Figure 9 and Figure 10 The internal moving transmission head 523 includes:

[0091] The second electric telescopic rod 5231 has one end fixed inside the inner cavity 5224 and is distributed along the inner cavity 5224 with the main body; a gap is reserved between the main body of the second electric telescopic rod 5231 and the inner cavity 5224.

[0092] Multiple fixing plates 5234 are in one-to-one correspondence with multiple guide grooves 5223; the fixing plates 5234 are slidably assembled inside the guide grooves 5223.

[0093] The inner support cylinder 5233 is movably sleeved on the positioning guide tube 5222 and can move along the positioning guide tube 5222.

[0094] Please see Figure 9 and Figure 10 The inner moving transmission head 523 also includes a second airbag pad 5234, which is sleeved on the outside of the inner support cylinder 5233 and can be inflated and deflated.

[0095] Therefore, taking four units of external transmission components 512 and four units of internal transmission components 521 as an example, after the intestine enters between the external transmission components 51 and the internal transmission components 52, the first unit of external transmission component 512 and the third unit of external transmission component 512 are simultaneously activated from the outside of the intestine, and the first unit of internal transmission component 521 and the third unit of internal transmission component 521 are simultaneously activated from the inside of the intestine. That is, the unit of external transmission component 512 inflates the first airbag cushion 518, and the first airbag cushion 518 expands inward, completing the action of the unit of external transmission component 512 on the intestine from the outside of the intestine; the unit of internal transmission component 521 inflates the second airbag cushion 5234, and the second airbag cushion 5234 expands outward, completing the action of the unit of internal transmission component 521 on the intestine from the inside of the intestine. The external transmission component 512 activates the first electric telescopic rod 515, which synchronously drives the outer support cylinder 517 and the first airbag pad 518 to move synchronously through extension and retraction. The internal transmission component 521 activates the second electric telescopic rod 5231, which synchronously drives the inner support cylinder 5233 and the second airbag pad 5234 to move synchronously through extension and retraction. This achieves a clamping point formed by the first external transmission component 512 and the first internal transmission component 521, and another clamping point formed by the third external transmission component 512 and the third internal transmission component 521. This ensures a stable traction unit between the two clamping points, which is beneficial for the intestine to be evenly stressed and move forward accurately and evenly in all directions, and to pass smoothly through the intestinal scraper 6.

[0096] During this process, the second and fourth external transmission components 512, which reset from the outside, and the second and fourth internal transmission components 521, which reset from the inside, receive the intestine that is synchronously pulled by the first and third external transmission components 512, the first internal transmission component 521, and the third internal transmission component 521. This allows the first and third external transmission components 512 and internal transmission components 521 to synchronously pull the intestine along with the second and fourth external transmission components 512 and internal transmission components 521. In this way, the odd-numbered and even-numbered external transmission components 512 and internal transmission components 521 alternately inflate, expand, and reset, forming a continuous alternating traction flow. This ensures that the intestine is always evenly supported by multiple sets of clamping points, achieving precise feeding without pulses or slippage, and laying a stable and constant tension material foundation for the subsequent intestinal scraping process.

[0097] In another embodiment of the present invention, please refer to Figures 11-13 The intestinal scraping component 6 includes an outer locking cylinder structure 61 and an inner scraping cylinder 62. The outer locking cylinder structure 61 is sleeved on the outside of the inner scraping cylinder 62, and the inner scraping cylinder 62 is located on the columnar centerline of the outer locking cylinder structure 61. The inner scraping cylinder 62 is fixed on the inner transmission component 52 and is linearly distributed with the inner transmission component 52. A storage cavity 622 is opened inside the inner scraping cylinder 62, and multiple scraping grooves 621 are opened on the outer surface of the inner scraping cylinder 62. The scraping grooves 621 are connected to the storage cavity 622 through a guide hole. A drain port connected to the storage cavity 622 is provided on the inner scraping cylinder 62. An oblique scraper 623 is provided at the outer opening of the scraping groove 621.

[0098] The feed guide hole and drain outlet in the figure are not shown because they are existing technologies, and their detailed structures can be found in existing literature and journals, and they can also be purchased directly from the market; they are not what this invention is meant to protect, and will not be described in detail here.

[0099] Please see Figure 11 and Figure 14 The outer locking cylinder structure 61 includes:

[0100] External locking cylinder 612;

[0101] The positioning ring 614 is sleeved and fixed to the outside of the outer locking cylinder 612;

[0102] Gas regulator 611 is fixed on the positioning ring 614; gas regulator 611 is used to be assembled inside the processing box 3;

[0103] The third airbag pad 613 is laid on the inner wall of the outer locking cylinder 612; the third airbag pad 613 is connected to the gas regulator 611, which can inflate and deflate the third airbag pad 613.

[0104] Traditional intestinal scrapers are all external. When the intestine passes through the scraper, the elasticity of the intestine allows foreign objects inside to easily evade the scraper due to intestinal deformation (for example, the "scraper" disclosed in the patent application number 202211289972.8, an automated sausage casing processing production equipment, is located externally, and foreign objects can evade the scraper when the intestine passes through it). Therefore, in this invention, after the intestine enters between the outer locking cylinder structure 61 and the inner scraping cylinder 62, the third airbag pad 613 periodically expands, squeezing the intestine onto the multiple scraping grooves 621 on the outer surface of the inner scraping cylinder 62. This allows foreign objects inside the intestine to enter the multiple scraping grooves 621 from all directions and be scraped away by the oblique scraper 623. The scraping efficiency and effect of foreign objects inside the intestine are high.

[0105] The first airbag pad 518, the second airbag pad 5234, and the third airbag pad 613 are all connected to an inflation tube and a deflation tube. Each inflation tube and deflation tube is connected to its own gas regulator 611. The gas regulator 611 has an inflator and a vacuum pump installed inside. The inflator and vacuum pump, as well as the inflation tube and deflation tube, are all existing technologies and can be purchased directly on the market or assembled by purchasing parts, etc. Whether they are publicly available or not does not affect the automated sausage casing processing component 4 to be protected, and will not be described in detail here.

[0106] In summary, the core of an automated sausage casing processing equipment lies in the innovative structural design and coordinated operation of the automated transmission component 5 (as a transmission mechanism) and the scraping component 6 (as a scraping mechanism), which systematically solves the technical problems of uneven intestinal force and incomplete removal of foreign matter in traditional equipment. Specifically, automated transmission components 5 are symmetrically arranged on both sides of the scraping component 6, and each automated transmission component 5 includes an outer transmission component 51 and an inner transmission component 52. During operation, the automated transmission component 5 on one side of the scraping component 6 activates the outer transmission component 51 and the inner transmission component 52, which simultaneously clamp the intestine from the outside and inside of the intestine and push it towards the scraping component 6. Meanwhile, the processing component 4 on the other side of the scraping component 6 clamps the intestine in the same way and pulls it outward from the scraping component 6, forming a two-way coordinated drive mode of "push forward and pull backward". This provides the intestine with a continuous and stable clamping force covering the entire circumference, enabling the intestine to move forward accurately and evenly in all directions, and completely avoiding the tearing damage caused by localized force concentration.

[0107] To achieve the refined control of clamping and driving as described above, this invention uses multiple units of external transmission element 512 of external transmission element 51 and multiple units of internal transmission element 521 of internal transmission element 52 as execution units. Taking four units as an example, when the intestine enters the working area between the external transmission element 51 and the internal transmission element 52, the first and third units of external transmission element 512 are activated simultaneously—by inflating the first airbag pad 518 to expand it inward, it gently conforms to the intestine from the outside; at the same time, the first and third units of internal transmission element 521 are activated simultaneously—by inflating the second airbag pad 5234 to expand it outward, it supports the intestine from the inside. After inflation, the first electric telescopic rod 515 of the external transmission component 512 extends, driving the external support cylinder 517 and the first airbag pad 518 to move axially; the second electric telescopic rod 5231 of the internal transmission component 521 extends simultaneously, driving the internal support cylinder 5233 and the second airbag pad 5234 to move axially, thus forming two stable clamping points from the first and third unit components, creating a traction unit that smoothly pushes the intestine. At the same time, the second and fourth external transmission components 512 and the internal transmission components 521 of the unit complete the deflation and reset of the airbags, and immediately receive the intestine delivered by the previous traction unit, then inflate, clamp, and drive; in this way, the odd-numbered and even-numbered external transmission components 512 and the internal transmission components 521 of the unit alternately inflate, extend, and reset, forming a continuous alternating traction flow, ensuring that the intestine is always evenly supported by multiple sets of clamping points, achieving precise feeding without pulses or slippage, and laying a stable and constant tension material foundation for the subsequent intestinal scraping process.

[0108] In the process of scraping the intestine, this invention breaks through the limitation of traditional scrapers that can only act on the outer surface of the intestine. Traditional equipment (such as the solution disclosed in the patent application number 202211289972.8) places the scraper outside the intestine. Since the intestine has significant elasticity, when foreign objects inside (such as residual mucosa and fat clumps) pass through the scraper with the deformation of the intestine, they are very easy to "dodge" and avoid the blade, resulting in incomplete scraping and repeated processing. This invention employs a closed intestinal scraping assembly consisting of an outer locking cylinder structure 61 and an inner scraping cylinder 62. When the intestine is uniformly fed into the annular gap between the outer locking cylinder 61 and the inner scraping cylinder 62 by the transmission system, the third airbag pad 613 periodically expands according to the control system command, pressing the intestinal wall uniformly against the outer surface of the inner scraping cylinder 62. The surface of the inner scraping cylinder 62 has multiple scraping grooves 621 distributed circumferentially and axially, with oblique scrapers 623 embedded in the grooves. Under the action of air pressure, the intestine is squeezed into the scraping grooves 621, and the foreign objects inside are forced into the grooves to make forced cutting contact with the oblique scrapers 623, thereby achieving all-round and thorough scraping of foreign objects from the inner wall of the intestine.

[0109] The transmission system adopts a clamping method with alternating traction on both the inner and outer sides, which not only makes the intestinal movement speed uniform and the position precise, but more importantly, it has already spread the intestinal circumferentially to the preset diameter before the intestinal scraping station. This "pre-spreading" state is exactly in time with the periodic expansion and squeezing action of the outer locking cylinder 61. The automated transmission component 5, as the transmission mechanism, continuously feeds the intestinal under stable tension. The air bladder expansion and squeezing of the scraping component 6, as the scraping mechanism, no longer needs to overcome the resistance caused by local accumulation or relaxation of the intestinal. The expansion force can be completely converted into effective scraping work, thus improving the scraping efficiency.

[0110] Traditionally, it is believed that the expansion and compression of the air bladder can easily lead to intestinal deformation and damage. However, since the automated transmission component 5 of this invention provides balanced clamping and constant speed traction in the entire circumference, the intestine is firmly positioned at the moment of pressure and the force is evenly distributed to the entire tube wall, thereby reducing the breakage rate of thin-walled sausage casings at the scraping station.

[0111] The odd-numbered and even-numbered external transmission components 512 and internal transmission components 521 alternately inflate, extend, and reset, forming a continuous alternating traction. Although not rigidly synchronized with the rhythm of the periodic expansion of the air bladder, they naturally form an optimal rhythm of "traction-compression-scraping-resetting" during continuous operation. This allows foreign objects inside the intestine to be repeatedly exposed to the scraper path during dynamic compression, improving the cleanliness of the scraping and eliminating the need for secondary manual inspection.
