The wire tying motor 36 is arranged on one side of the twisting box 37, and its output end is matched with the driving wheel 38. A toothed column 36 is transitionally matched at the output end of the wire tying motor 36 1, through the toothed column 361 meshing with the driving wheel 38, the driving wheel 38 is controlled to rotate, and the driving wheel 38, the driven wheel 34 and the twist box 37 are all provided with bearings, which improves the rotation effect of the driving wheel 38 and the driven wheel 34, and a rotating shaft 33 is provided on the driven wheel 34, when the front plate 372 and the rear plate 371 cooperate, one end of the rotating shaft 33 is located at the front plate 372 and extends out and cooperates with the wire guide 32, and the extruding piece 35 cooperates with the driven wheel 34, when the sausage is filled, the casing is filled and expanded through the extruding piece 35 to the twist wire tie 3, and the wire tie motor 36 outputs, so that the driving wheel 38 drives the synchronous wheel to rotate through the synchronous belt, and synchronously makes the wire guide 32 synchronously rotate the clamping mouth 45 decomposer to tie the sausage in sections, and the interval of each section of sausage is within the qualified range.

[0045] As a further embodiment of the present invention, the extruding member 35 includes a feed pipe 352 and a fixed plate 353 fixed to one side of the twist box 37. One end of the feed pipe 352 is clamped on the fixed plate 353, and a rubber sleeve 351 is provided at the other end. When the casing is filled with meat, it passes through the feed pipe 352, and the feed pipe 352 guides the sausage to move axially. When passing through the feed pipe 352, the rubber sleeve 351 causes the meat in the casing to be subjected to a certain pressure, making it more meaty and compact, thereby improving the quality and taste of the sausage.

[0046] As a further embodiment of the present invention, the wire guide 32 includes a support frame 328 and a wire storage wheel 321 clamped on the support frame 328, and the support frame 328 is respectively provided with a first wire hole 322, a second wire hole 323, a third wire hole 327 and a fourth wire hole 329, and the wire rope on the wire storage wheel 321 passes through the first wire hole 322, the second wire hole 323, the third wire hole 327 and the fourth wire hole 329 and cooperates with the clamping mouth 45, the support frame 328 has a threaded rod, one end of the threaded rod is slidably provided with a wire pressing wheel 324, and the other end thereof is threadedly connected with a nut 325, and the nut 325 is provided with a spring 326 that pushes the wire pressing wheel 324, and the wire storage wheel 321 is clamped on the support frame 328, and the wire storage wheel 321 can be removed and replaced after the wire rope is used up, and the replaced wire storage wheel 321 can be removed and replaced. The wire rope led out of the wire storage wheel 321 first passes through the fourth wire hole 329 and the third wire hole 327 in sequence, then passes through the second wire hole 323 and the first wire hole 322 around the wire pressing wheel 324, and the wire end is placed at the shrinkage hole 451. Further, when the bolt is tightened and moved with the support frame 328, a certain extrusion force is given to the spring 326 in sequence, so that the pressure plate presses the wire rope to improve the tightening effect of the wire rope on the sausage. Similarly, the closer the bolt is to the support frame 328, the greater the extrusion force of the spring 326 on the pressure plate. When tying the sausage, the wire guide 32 is clamped on the rotating shaft 33 and rotates synchronously with it to tie the sausage in sections. A cover 31 that cooperates with the twist box 37 is provided on one side of the wire wheel. The cover 31 is used to limit the axial sliding of the wire guide 32 so that it can only rotate on the rotating shaft 33.

[0047] As an embodiment further provided by the present invention, the feeding unit 6 includes a base 63 fixed on the box body 1, and a handle 62 is rotatably provided on the base 63. The feeding pipe 61 is clamped in the base 63, and the handle 62 plays a role in fixing the feeding pipe 61. The handle 62 is rotated clockwise so that one end of the handle 62 is engaged with the base 63, thereby fixing the feeding pipe 61 and enabling it to stably feed materials.

[0048] As a further embodiment of the present invention, the unloading unit 2 includes a unloading hopper 21 and a hinge 26 arranged on the box body 1. A sealing ring is arranged at the connection between the unloading hopper 21 and the box body 1. When the unloading hopper 21 and the box body 1 are fitted, the sealing between the two is improved. A chassis 25 is rotatably arranged between the hinges 26. A swing rod 22 cooperating with the hinge 26 is rotatably arranged on one side of the chassis 25. A unloading port 24 facing the vacuum blade metering pump 15 is opened on the chassis 25. The end of the unloading port 24 has a conical opening, which improves the unloading effect when the meat material falls, and the unloading port 24 corresponds to the blade 151. A card block 23 is provided on the chassis 25 to cooperate with the card slot 1531 on the cam 153. When the lower hopper 21 flips over and fits with the box body 1, the card block 23 is inserted into the card slot 1531 of the cam 153 to fix the cam 153. There are three hinges 26, two of which are symmetrically arranged on both sides of the chassis 25 for controlling the flipping of the chassis 25, and the other hinge 26 is used to cooperate with the swing rod 22 on the chassis 25. When the swing rod 22 is perpendicular to the box body 1, the lower hopper 21 can be flipped, and the relative swing rod 22 is horizontal to the upper plane of the box body 1 to fix the lower hopper 21.

[0049] As a further embodiment of the present invention, the vacuum vane metering pump 15 includes a cam 153 and a runner 152 rotatably connected to the groove 14, and the runner 152 is provided with vanes 151 in a circumferential array that fit with the cam 153. The runner 152 is annular, and the cam 153 is arranged at the inner circle of the runner 152. Twelve card slots are provided on the runner 152, and each card slot has a vane 151. The runner 152 is provided with a spacing hole that matches the vane 151. After the vane 151 has been running for a long time, The wear and tear forms a gap with the rotating wheel 152, and the spacing hole is used to limit the meat from entering the inner side of the rotating wheel 152, that is, the position of the fixed cam 153. The spacing hole also facilitates the operator to separate the blade 151 from the rotating wheel 152 for subsequent cleaning. At the same time, the blade 151 is tightly matched with the rotating wheel 152, and the gap is less than 0.02 mm, so that the rotating wheel 152 has good sealing performance, reducing the meat from entering the gap between the blade 151 and the rotating wheel 152 during the rotating sausage enema process. Since the hardness of the blade 151 is relatively large compared with the blade 151, the blade 151 is relatively large compared with the blade 151. The hardness of each component that the blade 151 contacts is slightly smaller, so the blade 151 is a vulnerable part. After long-term use and wear, the blade 151 can be replaced to increase the service life of the sausage twisting machine. The two spaced blades 151 form a closed space. When the wheel 152 rotates, the volume of the closed space changes from small to large or from large to small, so as to transport and squeeze the meat. The wheel 152 is rotated by the gearbox, and at the same time, the wheel 152 drives the blade 151 to follow the inner diameter curve of the groove 14 and the outer diameter curve of the cam 153. The channel operates, and the extension and contraction direction of the blade 151 is changed to achieve the effect of squeezing out the meat. The vacuum blade metering pump 15 is further divided into a vacuum zone, a feeding zone, a high-pressure zone and a closed zone. The vacuum pump is connected to the vacuum zone of the vacuum blade metering pump 15 through a first feeding pipe to extract vacuum, so that the impeller channel is in a vacuum state, and its negative pressure vacuum channel is transferred to the feeding zone to fill the meat. The blade 151 rotates with the impeller 152. When each blade 151 enters the high-pressure zone, it pushes and squeezes the meat entering the high-pressure zone, and finally discharges it into the feeding pipe 61.

[0050] As an embodiment further provided by the present invention, a vacuum gauge 12, a vacuum pump and a vacuum tank 18 are respectively provided on the box body 1. The vacuum tank 18 has three pipe joints, which are respectively connected to the vacuum gauge 12, the vacuum pump and the vacuum vane metering pump 15. The pipe joints are all provided with conveying pipes, and the first conveying pipe is connected to the vacuum vane metering pump 15, and the second and third conveying pipes are connected to the vacuum gauge 12 and the vacuum pump. The first conveying pipe is inserted into the vacuum tank 18 near the bottom of the vacuum tank 18. When the vacuum pump outputs, the meat material in the groove 14 is stored in the vacuum tank 18 through the first conveying pipe under the suction of the vacuum, and the second and third conveying pipes are arranged on the top of the vacuum tank 18, so as to prevent the meat material from flowing into the vacuum gauge 12 and the vacuum pump. The display 11 on the box body 1 is electrically connected to the vacuum pump to control the opening and closing of the vacuum. A vacuum cover plate 13 is provided at one end of the vacuum tank 18, which can be removed when cleaning the vacuum tank 18 to clean its interior.

[0051] Working principle: first, pour the seasoned meat into the lower hopper 21, and put the casing into the feeding pipe 61. The meat slides from the lower feeding port 24 along the inclined part of the lower hopper 21 to the vacuum vane metering pump 15, and then the reducer and the vacuum pump are operated. The vacuum pump improves the effect of the meat falling in the lower hopper 21, and the reducer drives the runner 152 located in the groove 14 to rotate so that the blades 151 rotate along the cam 153, so that the spacing between each blade 151 changes from large to small, pushing the meat into the feeding pipe 61, and then the meat is poured into the casing by the feeding pipe 61. As the casing continues to lengthen, it enters the guide pipe 352, and then the electrical signal is used to control the wire binding motor 36 and the cylinder 42 to output, so that the clamping nozzle 45 located on the box body 41 continuously swings, and the support frame 328 links the wire storage wheel 321 to rotate synchronously with the clamping nozzle 45, so as to bind the sausage in sections, so that the spacing of each section of the wire binding is kept within the qualified range, further improving the sausage production efficiency.

[0052] The technical solution of the present invention provides a solution that is significantly different from the prior art to address the technical problem that the prior art solution is too single. The parts not involved in the technical solution of this application are the same as the prior art or can be implemented by using the prior art and will not be described in detail.

[0053] The technical solutions in the above embodiments have clearly and completely described the contents of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
