Abstract

The application discloses a ham sausage processing system and a control method of the ham sausage processing system. The ham sausage processing system comprises a filling device, a sealing device and a cutter. The filling device intermittently fills materials into a cylindrical space formed by a casing to fill materials into a sausage section, and leaves a blank section. The sealing device comprises a top sealing part and a bottom sealing part used for sealing and welding the two ends of the length of the sausage section. The top sealing part and the bottom sealing part both comprise a high-frequency current welding assembly. The cutter is used for cutting the blank section. The cutting edge of the cutter is a continuous sawtooth structure. By adopting the high-frequency current welding assembly to seal the end of the ham sausage, compared with the aluminum buckle sealing mode, the problem that the aluminum buckle is easy to fall off and the aluminum buckle sharp may pierce the casing can be solved. When the casing is torn open, there is no blockage of the aluminum ring, and the casing is more simple to open. By adopting the continuous sawtooth cutter to cut the casing, the casing can be directly torn open by the sawtooth structure of the end cut, and the eating is more convenient.

Description

Technical Field

[0001] This invention relates to the field of ham sausage packaging technology, and in particular to a ham sausage processing system and a control method for the ham sausage processing system. Background Technology

[0002] Ham sausage is a meat product made primarily from fresh (frozen) livestock and poultry products and aquatic products. It is processed by trimming, mincing (or chopping), adding auxiliary materials and food additives, marinating (or not marinating), and then mixing (or tumbling, chopping, emulsifying), filling (or shaping) containers made of materials such as plastic casings, and cooking (steaming or sterilizing). It is convenient to carry and has a tender texture, making it a convenient food that is always on hand at home or while traveling.

[0003] In related technologies, aluminum wire is used to tie both ends of the sausage casing for sealing during production. This method has obvious drawbacks. On the one hand, the aluminum wire is easy to fall off, and the sharp points of the wire may puncture the casing, resulting in substandard products. On the other hand, sausages tied with aluminum wire need to be cut open with a knife, which is not convenient for consumption. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes a ham sausage processing system that solves the problems of aluminum buckles easily falling off and the sharp points of the aluminum buckles potentially puncturing the sausage casing, leading to product defects. Furthermore, the processed ham sausages are easier to open and more convenient to eat.

Detailed Implementation

[0022] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0024] The ham sausage processing system 1000 of the first aspect of the present invention is described below with reference to the accompanying drawings.

[0025] The ham sausage processing system 1000 according to an embodiment of the present invention is used to process sausage casings forming a tubular structure. The sausage casing includes a plurality of intestinal segments 2000 and hollow segments 3000 connected in sequence. Figure 1 As shown, the ham sausage processing system 1000 includes: a filling device 300, a sealing device 100, and a cutter 400. The filling device 300 intermittently fills the cylindrical space formed by the casing with material to fill the sausage section 2000, leaving the empty section 3000 empty. The sealing device 100 includes a top sealing member 100b and a bottom sealing member 100a spaced apart along a first direction X. Both the top sealing member 100b and the bottom sealing member 100a include a high-frequency current welding assembly 10. The top sealing member 100b is used to seal and weld one end of the sausage section 2000 along its length, and the bottom sealing member 100a is used to seal and weld the other end of the sausage section 2000 along its length. The cutter 400 is disposed along the first direction X on the side of the top sealing member 100b away from the bottom sealing member 100a. The cutter 400 is used to cut the empty section 3000, and the blade of the cutter 400 has a continuous serrated structure.

[0026] The ham sausage processing system 1000 of the present invention is used to process sausage casings that form a cylindrical structure. The filling device 300 intermittently fills the cylindrical space formed by the sausage casing with material, wherein the material may be minced meat, emulsified meat filling, etc.

[0027] The sausage casing has a continuous long roll structure. The filling device 300 intermittently fills the casing with material, that is, it fills the sausage body section 2000 with material, leaving the empty section 3000 of the casing empty, with an empty section 3000 sandwiched between two adjacent sausage body sections 2000. The sealing device 100 seals both ends of the sausage body section 2000, and then the cutter 400 cuts the empty section 3000, thus forming individual sausages.

[0028] In related technologies, aluminum wire is used to tie both ends of the sausage casing for sealing during production. However, this method has significant drawbacks. On the one hand, the aluminum wire is prone to falling off, and the sharp points of the wire may puncture the casing, resulting in substandard products. On the other hand, sausages tied with aluminum wire need to be cut open with a knife, which is inconvenient for consumption and leaves room for improvement.

[0029] To address the aforementioned issues, the sealing device 100 of the ham sausage processing system 100 in this embodiment of the invention employs a high-frequency current welding assembly 10. This assembly can melt the sausage casing at high temperature upon contact, heating and connecting the casings together to ensure a tight seal at the ham sausage's opening. Compared to sealing with aluminum buckles, this method solves the problems of aluminum buckles easily detaching and their sharp points potentially puncturing the casing, leading to product defects.

[0030] Furthermore, the blade 400 of the ham sausage processing system 1000 in this embodiment of the invention has a continuous serrated structure, resulting in a regular serrated cut. When eating the ham sausage, the casing can be torn open directly using the serrations at the cut, and since there is no aluminum ring obstructing the end of the ham sausage, the casing can be opened without the need for tools, making it more convenient to eat.

[0031] In addition, by using the high-frequency current welding assembly 10 to seal the end of the sausage segment 2000, the casing can be quickly melted at high temperature, so that the sealing point of the ham sausage is welded and sealed. This not only improves work efficiency, but also improves sealing performance and increases product qualification rate.

[0032] The ham sausage processing system 1000 according to an embodiment of the present invention uses a high-frequency current welding assembly 10 to seal the end of the ham sausage. Compared with sealing with aluminum buckles, this solves the problems of aluminum buckles easily falling off and the sharp points of the aluminum buckles potentially puncturing the casing, leading to product defects. When tearing open the casing, there is no aluminum ring to obstruct the process, making the casing easier to open. Furthermore, by using a continuously serrated cutter 400 to cut the casing, the serrated structure of the end cut allows the casing to be directly torn open without the need for tools, making consumption more convenient.

[0033] In some embodiments of the present invention, such as Figure 1 As shown, the high-frequency current welding assembly 10 includes two welding heads 1, with the inner side of the two welding heads 1 facing each other. The two welding heads 1 surround the intestinal segment 2000 to seal the intestinal segment 2000 through the inner side of the two welding heads 1.

[0034] During the sealing process, the two welding heads 1 are brought close together, and their inner surfaces together surround the sausage casing 2000 to heat and shape the casing, thus sealing the sausage. After the sealing weld, the two welding heads 1 are moved away from each other, causing the sausage casing 2000 to move.

[0035] The above design can meet the needs of assembly line operations and improve processing efficiency.

[0036] In some embodiments of the present invention, the welding head 1 is symmetrically arranged with respect to an axis extending along the first direction X, such as... Figure 2As shown, the welding head 1 includes: a middle portion 11, an edge portion 13, and a transition portion 12. The middle portion 11 is located at the middle position in the length direction of the welding head 1, and the middle portion 11 is constructed as a straight section extending along the length direction of the welding head 1. The edge portion 13 is located at both ends in the length direction of the welding head 1, and the edge portion 13 extends obliquely relative to the length direction of the welding head 1, and the cross-sectional shape of the edge portion 13 in the length direction of the welding head 1 is arc-shaped. The transition portion 12 connects the middle portion 11 and the edge portion 13, and the cross-sectional shape of the transition portion 12 in the length direction of the welding head 1 is arc-shaped.

[0037] The welding head 1 is symmetrically arranged relative to the axis extending along the first direction X. The welding head 1 has a regular shape, and the radial forces on both sides of the intestinal segment 2000 are uniform, which can improve the product qualification rate.

[0038] The inner surface of the middle portion 11 contacts the radial central region of the intestinal segment 2000, and the inner surface of the middle portion 11 together surrounds the intestinal segment 2000 to heat and shape the casing. By designing the middle portion 11 as a straight segment extending along the length of the welding head 1, the inner surface of the middle portion 11 and the central region of the casing are in direct contact, and the inner surfaces of the middle portions 11 of the two welding heads 1 are in close contact with each other, thereby improving the sealing density of the radial central region of the ham sausage.

[0039] The inner surface of the edge portion 13 is heated and plasticized at the radial edge of the intestinal segment 2000, so the edge portion 13 extends obliquely relative to the length direction of the welding head 1, and the cross-sectional shape of the edge portion 13 in the length direction of the welding head 1 is arc-shaped, which can be molded into an elliptical edge seal.

[0040] The transition portion 12 connects the middle portion 11 and the edge portion 13. The cross-sectional shape of the transition portion 12 in the length direction of the welding head 1 is arc-shaped. The transition portion 12 realizes a smooth transition from the middle portion 11 to the edge portion 13 and can form an elliptical edge seal.

[0041] Through the above design, the middle part 11 is precisely fitted to the flat surface of the casing, and the arc-shaped transition part 12 and the arc-shaped edge part 13 are adapted to the flat round end face contour of the casing, thus improving the uniformity of heating.

[0042] In some embodiments of the present invention, such as Figure 4 As shown, the casing moves in the first direction X along the direction from the bottom sealing member 100a to the top sealing member 100b, and an opening 131 is defined between the free ends of the two edge portions 13 of the welding head 1. The opening direction of the bottom sealing member 100a and the opening direction of the top sealing member 100b are opposite to each other.

[0043] The top sealing member 100b is located on the side of the bottom sealing member 100a away from the direction of movement of the casing. The bottom sealing member 100a first seals and welds the end of the intestinal segment 2000. Then, the casing moves along the first direction X to move the other end of the same intestinal segment 2000 to the top sealing member 100b. Finally, the top sealing member 100b seals and welds the other end of the intestinal segment 2000.

[0044] An opening 131 is defined between the free ends of the two edge portions 13 of the welding head 1, and the orientation of the opening 131 is away from the middle portion 11. By setting the opening direction of the bottom sealing member 100a and the opening of the top sealing member 100b opposite to each other, the bottom sealing member 100a first seals the end of the intestinal segment 2000 with welding, and the edge portion 13 of the bottom sealing member 100a forms an arc-shaped structure that bends toward the middle of the intestinal segment 2000; similarly, the edge portion 13 of the top sealing member 100b also forms an arc-shaped structure that bends toward the middle of the other end of the intestinal segment 2000.

[0045] In some embodiments of the present invention, the power density of the working area of ​​the middle portion 11 is greater than the power density of the working area of ​​the transition portion 12, and the power density of the working area of ​​the transition portion 12 is greater than the power density of the working area of ​​the edge portion 13.

[0046] Based on the high-frequency current heat conduction law and the thermal processing characteristics of the casing material (composite plastic), the power density of the middle part 11 is the largest, so as to achieve rapid melting and ensure the tightness of the seal.

[0047] The edge portion 13 has the lowest power density. This is understandable because the edge portion 13 is responsible for the heating and plasticizing of the casing at the radial edge of the sausage, where the casing bends and the material thickness is relatively concentrated, resulting in faster heat conduction. Using the same high power density as the middle portion 11 would easily lead to over-melting and reduced structural strength. Therefore, the edge portion 13 has the lowest power density, achieving both edge sealing and heat preservation, thus preventing brittleness after cooling.

[0048] The power density of the transition section 12 is less than that of the middle section 11, but greater than that of the edge section 13. This creates a temperature buffer zone between the middle section 11 and the edge section 13, allowing heat to be smoothly transferred from the high-power area to the low-power area. This eliminates local stress caused by sudden temperature changes and prevents the casing from breaking or cracking due to differences in thermal expansion and contraction.

[0049] Through the above design, in practical use, the sealing reliability is significantly improved. Because the gradient power matches the needs of different areas, the ham sausage melts fully in the middle section 11, while maintaining its shape well at the edges 13. Combined with subsequent pressure from the raised platform and the interlocking structure, the overall seal is dense and can withstand high-temperature sterilization, effectively reducing leakage and ensuring the integrity of the casing. Furthermore, it reduces edge cracking and damage caused by sudden temperature changes, thus effectively lowering the scrap rate during production.

[0050] Furthermore, the sealing device 100 in some embodiments of the present invention has a highly adaptable structure. All three power levels can be independently adjusted via a high-frequency generator, allowing for flexible parameter adjustments based on different thicknesses and materials of composite casings. It eliminates the need to replace the welding head 1, making it compatible with the production of various ham sausage specifications and improving equipment versatility. For example, the casing thickness is 0.08-0.2 mm.

[0051] In some embodiments of the present invention, the power density of the working area of ​​the middle portion 11 is 15-20 kW / cm²; and / or, the power density of the working area of ​​the transition portion 12 is 10-12 kW / cm²; and / or, the power density of the working area of ​​the edge portion 13 is 5-6 kW / cm².

[0052] The power density of the working area of ​​the middle part 11 is 15-20kW / cm², which is used for high-temperature melting of the central area of ​​the casing, so that the central area of ​​the casing is sealed and dense.

[0053] Optionally, the power density of the working area of ​​the intermediate part 11 can be 15kW / cm², 16kW / cm², 18kW / cm², 18.5kW / cm², 20kW / cm², etc.

[0054] The power density of the edge portion 13 is 5-6 kW / cm², which is used for edge insulation, shaping, and sealing reinforcement to reduce the brittleness of the casing edge due to excessive melting at high temperatures.

[0055] Optionally, the power density of the working area of ​​the edge portion 13 can be 5kW / cm², 5.2kW / cm², 5.5kW / cm², 5.6kW / cm², 6kW / cm², etc.

[0056] The power density of the transition section 12 is 10-12 kW / cm². The power density of the transition section 12 is less than that of the middle section 11, but greater than that of the edge section 13. This creates a temperature buffer zone between the middle section 11 and the edge section 13, allowing heat to be smoothly transferred from the high-power area to the low-power area, eliminating local stress caused by temperature changes, and preventing the casing from being damaged or cracked due to thermal expansion and contraction differences.

[0057] Optionally, the power density of the working area of ​​the transition section 12 can be 10kW / cm², 10.5kW / cm², 11kW / cm², 11.3kW / cm², 12kW / cm², etc.

[0058] In some embodiments of the present invention, such as Figure 2 As shown, the thickness of the middle portion 11 is the greatest, the thickness of the edge portion 13 is the smallest, and the thickness of the transition portion 12 is less than the thickness of the middle portion 11 but greater than the thickness of the edge portion 13. Furthermore, the thickness of the transition portion 12 gradually decreases from the middle portion 11 to the edge portion 13, and the thickness of the edge portion 13 also gradually decreases from the middle portion 11 to the edge portion 13. In this way, when the two welded heads 1 are joined together, the middle portion 11 is less prone to deformation, while the transition portion 12 and the edge portion 13 are more easily deformed to surround and enclose the sausage, adapting to the stress on the flattened, round end face of the casing after it has been flattened. Moreover, the variation in thickness of the transition portion 12 and the edge portion 13 reduces stress concentration and improves the operational reliability of the welded head 1.

[0059] In some embodiments of the present invention, the thickness of the middle portion 11 is 5 mm, the thickness of the edge portion 13 is 2-3 mm, and the thickness of the transition portion 12 is 3-5 mm.

[0060] In some embodiments of the present invention, the two welding heads 1 are arranged axially symmetrically. The two welding heads 1 are identical in shape and size, and when the two welding heads 1 are together, the intestinal segment 2000 is subjected to uniform force, which can improve the uniformity of heating and improve the working reliability of the welding heads 1.

[0061] In some embodiments of the present invention, such as Figure 3 As shown, the two welding heads 1 of the top sealing member 100b are the first welding head and the second welding head, respectively. The two transition portions 12 of the first welding head are provided with interlocking protrusions, and the two transition portions 12 of the second welding head are provided with interlocking grooves. The interlocking protrusions and the interlocking grooves are engaged in a meshing fit. And / or, the two welding heads 1 of the bottom sealing member 100a are the third welding head and the fourth welding head, respectively. The two transition portions 12 of the third welding head are provided with interlocking protrusions, and the two transition portions 12 of the fourth welding head are provided with interlocking grooves. The interlocking protrusions and the interlocking grooves are engaged in a meshing fit.

[0062] By setting interlocking ridges and interlocking grooves, the transition part 12 forms a dual sealing structure of physical interlocking and heat sealing during sealing, thereby improving the tensile strength of the seal.

[0063] In some embodiments of the present invention, such as Figure 3 As shown, a clamping boss 16 is integrally formed at the edge of the edge portion 13, and the local pressure of the clamping boss 16 is greater than the pressure at the middle position in the length direction of the welding head 1.

[0064] By providing a clamping boss 16, when the welding head 1 is clamped, the clamping boss 16 will contact the edge of the casing first, improving the sealing effect. The local pressure of the clamping boss 16 is greater than the pressure at the middle position along the length of the welding head 1, ensuring that there are no leaks at the edge seal.

[0065] In some embodiments of the present invention, the clamping pressure of the welding head 1 is adjusted by using a pressure sensor to make the local pressure at the clamping boss 16 reach 0.39MPa.

[0066] In some embodiments of the present invention, such as Figure 3 As shown, a ceramic protective ring 17 is nested at the edge of the pressing boss 16. The outer edge of the ceramic protective ring 17 is flush with the outer edge of the pressing boss 16. This can prevent high-frequency current leakage from burning the equipment and operators, and also reduce the occurrence of damage caused by direct friction between the edge of the casing and the metal.

[0067] In some embodiments of the present invention, such as Figure 5 As shown, the sealing device 100100 also includes a cooling component 20, which includes a cooling pipe 21 embedded in the welding head 1. The shortest distance between the cooling pipe 21 and the inner side of the welding head 1 is 2-3 mm. A cooling channel 211 is defined inside the cooling pipe 21, and the heat exchange medium flows through the cooling channel 211 to cool the welding head 1.

[0068] By embedding a cooling pipe 21 inside the welding head 1, the structural stability of the welding head 1 can be improved and the working reliability of the welding pipe can be enhanced compared to the design method of directly drilling the flow channel inside the welding head 1.

[0069] Both excessively small and excessively large shortest distances between the cooling pipe 21 and the inner surface of the welding head 1 are detrimental to the operation of the welding head 1. When the shortest distance is too small, the high heating temperature of the welding head 1 will reduce the service life of the cooling pipe 21. Conversely, when the shortest distance is too large, it will reduce cooling efficiency and hinder the processing of sausage casings by the welding head 1. Therefore, a shortest distance of 2-3 mm between the cooling pipe 21 and the inner surface of the welding head 1 is preferable. This not only protects the cooling pipe 21 and extends its service life but also improves cooling efficiency, which is beneficial for the processing of sausage casings by the welding head 1.

[0070] The moment the welding head 1 is completed, the cooling component 20 is activated, delivering the heat exchange medium into the cooling channel 211. Due to the short heat exchange cutoff time, the sealing surface is rapidly cooled and shaped.

[0071] In some embodiments of the present invention, the cooling pipe 21 is a high-temperature resistant stainless steel pipe, and the heat exchange medium is low-temperature cooling water.

[0072] In some embodiments of the present invention, the cooling component 20 is connected to the water circulation system in the ham sausage production line. The cooling component 20 also includes a solenoid valve and an air blowing mechanism. The cooling component 20 is activated the instant the welding head 1 is completed, the solenoid valve opens, and low-temperature circulating cooling water at 0-15°C is supplied to the cooling channel 211. The water flow time is controlled within 0.2 seconds, causing the sealing surface temperature to drop from 180°C to below 80°C within 0.2 seconds, achieving rapid cooling and shaping of the sealing surface. After cooling is complete, the solenoid valve closes, and residual moisture in the cooling channel 211 is discharged through the air blowing mechanism, reducing the impact on the next welding operation.

[0073] In some embodiments of the present invention, such as Figure 1 and Figure 6 As shown, the ham sausage processing system 1000 also includes an exhaust device 500, which includes a pre-pressure roller 51. The pre-pressure roller 51 is rotatably arranged with its own axis as the rotation center. The pre-pressure roller 51 is located between the top sealing member 100b and the bottom sealing member 100a. There are two pre-pressure rollers 51, which are spaced apart along the second direction Y. The second direction Y is perpendicular to the first direction X. The pre-pressure roller 51 can be moved along the second direction Y. The pre-pressure roller 51 is used to abut against the sausage body section 2000 to provide pre-pressure, and rolls relative to the sausage body section 2000 to expel the air between the casing and the material.

[0074] By setting the pre-pressure roller 51, pre-pressure is applied to the casing section from both sides of the sausage body section 2000. On the one hand, it can eliminate the gap between the casing and the material. Through bidirectional rolling pre-pressure, air between the casing and the material can be quickly discharged. At the same time, the material is pre-compressed, which can improve problems such as incomplete welding and bulging caused by air during the welding of the sealing device 100, as well as the problems of bottom bulging and leakage during the filling process. On the other hand, it can protect the integrity of the casing. The pre-pressure roller 51 can be moved along the second direction Y to adapt to sausage body sections 2000 of different sizes, improve casing damage caused by rigid contact, and reduce the scrap rate.

[0075] In some specific embodiments of the present invention, the pre-pressure roller 51 is a silicone part, and the outer layer hardness of the pre-pressure roller 51 is set to Shore 70A, which can achieve pre-pressure and degassing without damaging the surface of the casing.

[0076] In some embodiments of the present invention, such as Figure 6As shown, the exhaust device 500 also includes: guide rods 52, springs 53, and sliders 54. There are two guide rods 52, which are fixedly connected to the two welding heads 1 of the top sealing member 100b respectively. The guide rods 52 move synchronously with the movement of the welding heads 1. A slide 521 extending along the length direction of the guide rods 52 is defined inside the guide rods 52. The springs 53 are disposed in the slide 521, and one end of the springs 53 is connected to the end of the slide 521. The sliders 54 are at least partially located in the slide 521, and the slide 521 is restricted to move along the slide 521. The sliders 54 are connected to the other end of the springs 53. The preload rollers 51 are fixedly connected to the sliders 54.

[0077] The guide rod 52 moves synchronously with the welding head 1. The guide rod 52 then drives the spring 53, slider 54, and pre-pressure roller 51 to move together. This allows the pre-pressure roller 51 to move along the second direction Y towards the intestinal segment 2000 while the welding head 1 moves towards it, achieving synchronous movement. By having the welding head 1, which already moves relative to the intestinal segment 2000, drive the pre-pressure roller 51, the number of driving components required for the pre-pressure roller 51 can be reduced, simplifying the structure and lowering manufacturing costs.

[0078] One end of the spring 53 is connected to the end of the slide rail 521, and the other end of the spring 53 is connected to the slider 54. The slider 54 is fixedly connected to the pre-pressure roller 51. In this way, the spring 53 can provide stable pressure to the pre-pressure roller 51, improving the reliability of the force applied by the pre-pressure roller 51 to the intestinal segment 2000. This ensures consistent pressure at multiple locations on the intestinal segment 2000, providing a stable end face for subsequent gradient welding and interlocking sealing, further guaranteeing the uniformity of sealing quality, and effectively controlling the fluctuation of its sealing strength.

[0079] In some embodiments of the present invention, the ham sausage processing system 1000 further includes an adjustment mechanism that can drive the top sealing member 100b and / or the bottom sealing member 100a to move along a first direction X. This allows it to accommodate sausage segments 2000 of different specifications, thus broadening its application range.

[0080] The control method of the ham sausage processing system of the second aspect of the present invention is described below with reference to the accompanying drawings.

[0081] According to an embodiment of the present invention, a control method for a ham sausage processing system, wherein the ham sausage processing system is a ham sausage processing system 1000 according to a first aspect of the present invention, the control method includes at least the following steps: S1: a bottom sealing member 100a is sealed and welded to one end of the sausage body segment 2000 along its length direction; S3: a filling device 300 fills the sausage body segment 2000 with material; S5: the casing moves along a first direction X from the bottom sealing member 100a to the top sealing member 100b, an exhaust device 500 abuts against the sausage body segment 2000 to provide pre-pressure, and the pre-pressure roller 51 of the exhaust device 500 rolls from one end of the sausage body segment 2000 along its length direction to the other end of the sausage body segment 2000 to expel air between the casing and the material; S7: a top sealing member 100b is sealed and welded to the other end of the sausage body segment 2000 along its length direction; S9: a cutter 400 cuts the empty segment 3000, forming a serrated cut at the cut.

[0082] The casing has been processed into a cylindrical structure, comprising multiple intestinal segments 2000 and hollow segments 3000 connected in sequence, such as... Figure 7 As shown, the first intestinal segment 2000a, the first empty segment 3000a, the second intestinal segment 2000b, the second empty segment 3000b, and the third intestinal segment 2000c are connected in sequence. In practical applications, the length of the intestine is longer, including more intestinal segments 2000 and empty segments 3000. Here, only the processing of the above segments is described for ease of understanding.

[0083] The sealing device 100 sequentially seals and welds both ends of the first intestinal segment 2000a, the second intestinal segment 2000b, and the third intestinal segment 2000c. When sealing the first intestinal segment 2000a, firstly, as... Figure 7 As shown, the bottom sealing member 100a of the sealing device 100 is welded to one end of the first intestinal segment 2000a, thus forming a structure where one end of the intestinal segment 2000 is sealed and the other end is open. Next, the filling device injects material from the other end opening of the intestinal segment 2000, filling it completely. Finally, the casing moves along the first direction X from the sealing member to the top sealing member 100b, as shown... Figure 8 As shown, the process continues until the other end of the first intestinal segment 2000a moves to the top sealing member 100b, whereby the top sealing member 100b seals and welds the other end of the first intestinal segment 2000a, thus completing the sealing of both ends of the first intestinal segment 2000a.

[0084] It is worth noting that, such as Figure 8As shown, when the casing moves along the first direction X from the sealing member to the top sealing member 100b until the other end of the first sausage segment 2000a mates with the top sealing member 100b, the end of the second sausage segment 2000b closest to the first sausage segment 2000a also moves to a position where it mates with the bottom sealing member 100a. At this time, the first empty segment 3000a between the first sausage segment 2000a and the second sausage segment 2000b is located between the bottom sealing member 100a and the top sealing member 100b.

[0085] In this way, when the top sealing member 100b seals the first intestinal segment 2000a, the bottom sealing member 100a can also seal the segment of the second intestinal segment 2000b simultaneously or at a very short interval, resulting in high working efficiency for both the top sealing member 100b and the bottom sealing member 100a.

[0086] Similarly, during the end-sealing and injection process, the second intestinal segment 2000b, such as Figure 9 As shown, it also moves along the first direction X from the sealing member to the top sealing member 100b, so that the top sealing member 100b mates with the other end of the second intestinal segment 2000b. At this time, the end of the third intestinal segment 2000c near the second intestinal segment 2000b also moves to a position to mate with the bottom sealing member 100a. At this time, the second empty segment 3000b between the second intestinal segment 2000b and the third intestinal segment 2000c is located between the bottom sealing member 100a and the top sealing member 100b.

[0087] When the end of the third intestinal segment 2000c near the second intestinal segment 2000b moves to a position that engages with the bottom sealing member 100a, the end of the second intestinal segment 2000b is still engaging with the top sealing member 100b, while the first intestinal segment 2000a is no longer engaging with the sealing device 100. At this time, the first empty segment 3000a moves to the cutter 400, and the cutter 400 cuts off the first empty segment 3000a, thereby making the first intestinal segment 2000a and part of the empty segment 3000 form a separate entity.

[0088] The control method of the ham sausage processing system 1000 according to an embodiment of the present invention can improve work efficiency.

[0089] In some embodiments of the present invention, step S1 further includes at least the following steps: S11: the two welding heads 1 of the bottom sealing member 100a move toward the casing; S12: the edge portion 13 of the welding head 1 abuts against the edge of the intestinal segment 2000, and the edge portion 13 clamps the intestinal segment 2000; S13: the middle portion 11 and the transition portion 12 of the welding head 1 clamp the intestinal segment 2000; S14: the middle portion 11, the edge portion 13 and the transition portion 12 are heated synchronously according to a preset power gradient; S15: the cooling channel 211 in the welding head 1 of the bottom sealing member 100a is circulated with a heat exchange medium to cool the working area of ​​the welding head 1, so that the sealing surface of the intestinal segment 2000 is cooled and shaped; S16: the heat exchange medium in the cooling channel 211 is emptied; S17: the two welding heads 1 of the bottom sealing member 100a are reset.

[0090] The two welding heads 1 of the bottom sealing member 100a move under the drive of the control system. The edge part 13 of the welding head 1 first abuts against the edge of the intestinal segment 2000 to form a local pressure seal. Then the middle part 11 and the transition part 12 clamp the intestinal segment 2000.

[0091] Welding is performed in step S14. At the moment the welding is completed in step S14, step S15 is performed. The control system activates the solenoid valve corresponding to the hollow cooling channel 211. The cooling water circulation system introduces low-temperature circulating cooling water at 10-15°C into the cooling channel 211. The heat is rapidly conducted through the metal substrate of the welding head 1, causing the temperature of the sealing surface to drop from 180°C to below 80°C within 0.2s. This achieves rapid cooling and shaping of the sealing surface, preventing the casing from sticking back or deforming due to natural cooling.

[0092] After cooling is complete, the solenoid valve closes, and step S16 is performed. The air blowing mechanism introduces compressed air into the cooling channel 211 to discharge the residual cooling water.

[0093] In some embodiments of the present invention, step S7 further includes at least the following steps: S71: the two welding heads 1 of the top sealing member 100b move toward the casing; S72: the edge portion 13 of the welding head 1 abuts against the edge of the intestinal segment 2000, and the edge portion 13 clamps the intestinal segment 2000; S73: the middle portion 11 and the transition portion 12 of the welding head 1 clamp the intestinal segment 2000; S74: the middle portion 11, the edge portion 13 and the transition portion 12 are heated synchronously according to a preset power gradient; S75: the cooling channel 211 in the welding head 1 of the top sealing member 100b is circulated with a heat exchange medium to cool the working area of ​​the welding head 1, so that the sealing surface of the intestinal segment 2000 is cooled and shaped; S76: the heat exchange medium in the cooling channel 211 is emptied; S77: the two welding heads 1 of the top sealing member 100b are reset.

[0094] The top sealing component 100b and the bottom sealing component 100a adopt the same pressurization method and the same gradient heating mode. Furthermore, the cooling parameters of the top sealing component 100b are the same as those of the bottom sealing component 100a to achieve rapid cooling and shaping of the top sealing surface, thereby preventing the casing from sticking back and deforming.

[0095] By using the same pressurization method, gradient heating mode, and cooling parameters for the top sealing component 100b and the bottom sealing component 100a, the sealing effect at both ends of the intestinal segment 2000 is consistent, thereby improving the product qualification rate.

[0096] In other embodiments of the present invention, the two welding heads 1 of the bottom sealing member 100a are respectively a third welding head and a fourth welding head. The two transition portions 12 of the third welding head are provided with interlocking protrusions, and the two transition portions 12 of the fourth welding head are provided with interlocking grooves. The interlocking protrusions and the interlocking grooves engage with each other. The welding head 1 of the bottom sealing member 100a has a pressing boss 16 integrally formed at the edge of the edge portion 13, and a ceramic protective ring 17 is nested at the edge of the pressing boss 16.

[0097] Step S1 further includes at least the following steps: S11: The third welding head and the fourth welding head move toward the casing; S12: The edge portion 13 of the welding head 1 abuts against the edge of the intestinal segment 2000, and the pressing protrusion 16 of the edge portion 13 clamps the intestinal segment 2000; S13: The middle portion 11 and the transition portion 12 of the welding head 1 clamp the intestinal segment 2000, and the biting protrusion of the transition portion 12 engages with the biting groove; S14: The middle portion 11, the edge portion 13 and the transition portion 12 are heated synchronously according to a preset power gradient; S15: The cooling channel 211 in the welding head 1 of the bottom sealing member 100a is circulated with heat exchange medium to cool the working area of ​​the welding head 1, so that the sealing surface of the intestinal segment 2000 is cooled and shaped; S16: The heat exchange medium in the cooling channel 211 is emptied; S17: The third welding head and the fourth welding head are reset.

[0098] In other embodiments of the present invention, the two welding heads 1 of the top sealing member 100b are respectively a first welding head and a second welding head. The two transition portions 12 of the first welding head are provided with interlocking protrusions, and the two transition portions 12 of the second welding head are provided with interlocking grooves. The interlocking protrusions and the interlocking grooves engage with each other. The welding head 1 of the top sealing member 100b has a pressing boss 16 integrally formed at the edge of the edge portion 13, and a ceramic protective ring 17 is nested at the edge of the pressing boss 16.

[0099] Step S7 further includes at least the following steps: S71: The first welding head and the second welding head move toward the casing; S72: The edge portion 13 of the welding head 1 abuts against the edge of the intestinal segment 2000, and the clamping protrusion 16 of the edge portion 13 clamps the intestinal segment 2000; S73: The middle portion 11 and the transition portion 12 of the welding head 1 clamp the intestinal segment 2000, and the biting protrusion of the transition portion 12 engages with the biting groove; S74: The middle portion 11, the edge portion 13 and the transition portion 12 are heated synchronously according to a preset power gradient; S75: The cooling channel 211 in the welding head 1 of the top sealing member 100b is circulated with a heat exchange medium to cool the working area of ​​the welding head 1, so that the sealing surface of the intestinal segment 2000 is cooled and shaped; S76: The heat exchange medium in the cooling channel 211 is emptied; S77: The first welding head and the second welding head are reset.

[0100] In some embodiments of the present invention, step S5 further includes at least the following steps: S51: The casing moves along the first direction X from the bottom sealing member 100a to the top sealing member 100b; S52: The two welding heads 1 of the top sealing member 100b move toward the casing, and the welding heads 1 simultaneously drive the two guide rods 52 to move toward the casing. The guide rods 52 drive the pre-pressure roller 51 to abut against the sausage section 2000, and the spring 53 provides pre-pressure to the welding heads 1; S53: The pre-pressure roller 51 rolls around its own axis in contact with the casing, expelling the air gap between the casing and the material; S54: Under the pressure of the welding heads 1 of the top sealing member 100b, the pre-pressure roller 51 retracts along the slide 521 in the guide rod 52, and the pre-pressure roller 51 resets.

[0101] The pre-compression roller 51 rolls around its own axis in close contact with the sausage casing, rolling from one end of the sausage section 2000 along its length to the other end, achieving bidirectional pre-compression and venting. This removes air from the gap between the casing and the material, while simultaneously pre-compressing the bottom material by 1-2mm, smoothing the casing end face, eliminating gaps between the casing and the meat filling, and preventing bottom bulging or leakage.

[0102] In some embodiments of the present invention, step S9 further includes at least the following steps: S91: the cutter 400 cuts off the empty segment 3000, forming a serrated cut at the cut; S92: the micro-trimming structure on the blade of the cutter 400 simultaneously removes the edge burrs, which fall into the corresponding waste collection trough; S93: the cutter 400 resets and stands ready.
