Description

Technical Field

[0001] This utility model belongs to the technical field of enema twisting machine, specifically relating to a fully automatic enema twisting machine with a stop valve. Background Technology

[0002] Sausage, also known as cured sausage, is a food made using very ancient food production and meat preservation techniques. Animal meat is minced, mixed with seasonings, and then stuffed into casings to form a long, cylindrical tube-shaped food. Sausages are made by stuffing seasoned meat into small intestines (or sometimes large intestines) or artificial casings, and then drying them. A sausage stuffing and twisting machine is used in the sausage production process.

[0003] In the sausage stuffing and twisting machine, the sausage casing is fitted onto the discharge pipe during the twisting process. The meat material in the feed hopper is then poured into the casing through the discharge pipe by the extrusion mechanism, thus achieving the twisting. However, during the twisting process, because the extrusion of the meat material in the feed hopper is controlled by the extrusion pressure of the extrusion mechanism, the residual pressure in the feed hopper can easily cause the meat material to continuously overflow from the discharge pipe when the equipment starts or stops or when abnormal conditions occur (such as casing breakage or material jamming). This not only wastes raw materials but also contaminates the equipment and the production environment, increases cleaning costs, and raises food safety risks. Utility Model Content

[0011] In this utility model, the clamping mechanism includes an elastic clamping cone ring and an adjusting clamping member.

[0020] See Figures 1 to 12 This embodiment discloses a fully automatic sausage stuffing and twisting machine with a stop valve, including a machine housing 1, a material tank 2 for putting in meat, an extrusion mechanism 3 for squeezing the meat in the material tank 2, a twisting mechanism 4 for stuffing the meat into sausage casings, and a stop valve 5 for controlling the on / off state of the pipeline for conveying the meat in the material tank 2 to the twisting mechanism 4. The material tank 2 is installed in the machine housing 1, and the extrusion mechanism 3 is adapted to the material tank 2. The material tank 2 is provided with a discharge port 21, the inlet end of the stop valve 5 is connected to the discharge port 21, and the outlet end of the stop valve 5 is connected to the discharge pipe 41 of the twisting mechanism 4. During the twisting process, when the equipment starts up, stops, or encounters an abnormal operating condition requiring the twisting operation to be stopped, the extrusion mechanism 3 stops working, and the stop valve 5 closes, blocking the pipeline for conveying meat between the material tank 2 and the twisting mechanism 4. This prevents meat from continuously overflowing from the material tank through the twisting mechanism 4 when the equipment stops twisting, thus avoiding waste and contamination of the equipment and production environment. When the equipment needs to be restarted for twisting, simply open the stop valve 5 to connect the pipeline for conveying meat between the material tank 2 and the twisting mechanism 4. The extrusion mechanism 3 can then work to extrude the meat in the material tank 2 into the twisting mechanism 4, which then fills the sausage casing. In this embodiment of the fully automatic sausage stuffing and twisting machine, by configuring the stop valve 5 between the outlet 21 of the material tank 2 and the outlet pipe 41 of the twisting mechanism 4, the meat extrusion can be controlled to avoid waste of meat and contamination of the equipment and production environment.

[0021] In a preferred embodiment, the stop valve 5 includes a valve body 51, a valve core 52, and a control mechanism 53 for controlling the valve core 52 to switch between open and closed states. The valve core 52 is movably installed in the valve body 51, and the control mechanism 53 is connected to the valve core 52. The valve core 52 is controlled by the control mechanism 53 to switch between open and closed states to realize the on / off control between the feed end and the discharge end of the stop valve 5. Specifically, the valve core 52 is rotatably installed inside the valve body 51. The valve core 52 is provided with a material passage hole 521, which passes through the valve core 52. A stop wall 522 is provided on the outside of the material passage hole 521. The control mechanism 53 drives the valve core 52 to rotate and switch between open and closed states. When the control mechanism 53 drives the valve core 52 to rotate until the material passage hole 521 is directly opposite the inlet and outlet ends of the stop valve 5, the stop valve 5 is in the open state, and the pipeline for conveying meat between the material bucket 2 and the twisting mechanism 4 is connected, allowing the meat to be squeezed out from the material bucket 2 into the twisting mechanism 4. When the control mechanism 53 drives the valve core 52 to rotate until the stop wall 522 is directly opposite the inlet and outlet ends of the stop valve 5, the stop valve 5 is in the closed state, and the pipeline for conveying meat between the material bucket 2 and the twisting mechanism 4 is blocked by the stop wall 522, thereby preventing the meat from entering the twisting mechanism 4 from the material bucket. Specifically, the control mechanism 53 includes a stop motor 531 and a reducer 532. The stop motor 531 is connected to the input shaft of the reducer 532, and the output shaft of the reducer 532 is connected to the valve core 52 via a valve core drive shaft 54. The fit between the valve core drive shaft 54 ​​and the reducer 532 is relatively tight and does not require frequent disassembly. However, after the sausage stuffer has been used, the valve core 52 contains meat, which needs to be removed and cleaned to prevent it from becoming smelly. Therefore, the valve core drive shaft 54 ​​and the valve core 52 are detachably connected to facilitate the removal and cleaning of the valve core 52. When the stop motor 531 is working, it drives the valve core drive shaft 54 ​​and the valve core 52 to rotate via the reducer 532, controlling the opening and closing state of the stop valve 5. Furthermore, the valve core 52 is connected to a stop knob 523 for manually controlling the rotation of the valve core 52 to switch between open and closed states. The stop knob 523 extends from the top of the housing 1. When the control mechanism 53 malfunctions or experiences a power outage and cannot control the rotation of the valve core 52, the valve core 52 can be controlled by rotating the stop knob 523, thereby preventing the meat from overflowing from the hopper through the twisting mechanism 4. Furthermore, the stop valve 5 is also equipped with a proximity switch 30 for identifying the open and closed states. A protrusion adapted to the proximity switch 30 is provided at the bottom of the valve core 52. The protrusion rotates synchronously with the valve core 52. When the valve core 52 rotates to the open state, the protrusion rotates to a position opposite to the proximity switch 30, causing the proximity switch to generate an electrical signal, thus identifying that the stop valve 5 is in the open state. When the valve core 52 rotates to the closed state, the protrusion rotates to a position offset from the proximity switch 30, and the proximity switch does not generate an electrical signal, thus identifying that the stop valve 5 is in the closed state.

[0022] In a preferred embodiment, the twisting mechanism 4 includes a discharge pipe 41 for filling the casing with meat, a sleeve 42 for fitting the casing, a clamping mechanism 43 for pressing the casing, a synchronizing mechanism 44 for synchronously rotating to twist the casing, and a clamping and rolling mechanism 45 for clamping the casing body to cooperate with the twisting of the casing. One end of the discharge pipe 41 is connected to the discharge end of the stop valve 5, and the other end extends outward to form a twisting end, through which the meat is filled into the casing. The sleeve 42 is fitted onto the outside of the discharge pipe 41 and is fixedly connected to the discharge pipe 41. The clamping mechanism 43 is located outside the twisting end and clamps the casing to the outside of the discharge pipe 41, preventing the meat from flowing back into the sleeve 42 and driving the meat outward. The synchronizing mechanism 44 is connected to the discharge pipe 41 and the pressing mechanism 43, driving the discharge pipe 41 and the pressing mechanism 43 to rotate synchronously. At the same time, the discharge pipe 41 and the sleeve 42 are relatively fixedly connected, so the sleeve 42 rotates synchronously with the discharge pipe 41. The clamping and rolling mechanism 45 is located in front of the twisting end. When the discharge pipe 41 fills the casing with meat, the casing filled with meat expands to form a sausage. The clamping and rolling mechanism 45 clamps the sausage body, so that the outer sausage body will not rotate when the synchronizing mechanism 44 rotates to twist the casing. One end is stationary and the other end rotates, thereby achieving the purpose of twisting. While clamping the sausage body, the clamping and rolling mechanism 45 rolls in the direction of outward conveying of the sausage body in conjunction with the axial direction of the sausage body, so that the sausage body can be continuously conveyed outward.

[0023] Specifically, the synchronization mechanism 44 includes a synchronization power source 441, a synchronization shaft 442, a first synchronization pulley 443, a second synchronization pulley 444, a first synchronization belt 445, a third synchronization pulley 446, a fourth synchronization pulley 447, and a second synchronization belt 448. The synchronization power source 441 is connected to one end of the synchronization shaft 442, and the two ends of the synchronization shaft 442 are respectively connected to the first synchronization pulley 443 and the second synchronization pulley 444. In this embodiment, the discharge pipe 41 is a split structure, composed of multiple interconnected pipes; of course, the discharge pipe 41 can also be a one-piece structure. The third synchronization pulley 446 and the fourth synchronization pulley 447 are respectively connected to the outer surfaces of the discharge pipe 41 and the pressing mechanism 43. On one side, the first synchronous pulley 443 and the third synchronous pulley 446 are arranged opposite each other and connected by the first synchronous belt 445; the second synchronous pulley 444 and the fourth synchronous pulley 447 are arranged opposite each other and connected by the second synchronous belt 448; when the synchronous power source 441 rotates, it drives the synchronous shaft 442 to rotate, the synchronous shaft 442 drives the first synchronous pulley 443 and the second synchronous pulley 444 to rotate, the first synchronous pulley 443 drives the third synchronous pulley 446 to rotate through the first synchronous belt 445, and the third synchronous pulley 446 drives the discharge pipe 41 to rotate; the second synchronous pulley 444 drives the fourth synchronous pulley 447 to rotate through the second synchronous belt 448, and the fourth synchronous pulley 447 drives the pressing mechanism 43 to rotate. The synchronous power source 441 can be a motor directly driven by the synchronous shaft 442; or it can be indirectly driven by a motor driving a transmission belt assembly or a transmission chain assembly, etc.

[0024] Specifically, the pressing mechanism 43 includes an elastic pressing cone ring 431 and an adjusting pressing member 432. The elastic pressing cone ring 431 is fitted onto the outside of the discharge pipe 41 and is located inside the fourth synchronous wheel 447. The inner wall of the fourth synchronous wheel 447 abuts against the outer conical surface of the elastic pressing cone ring 431. The adjusting pressing member 432 is threadedly connected to the inside of the fourth synchronous wheel 447. The front end of the adjusting pressing member 432 abuts against the end face of the elastic pressing cone ring 431. When the adjusting pressing member 432 adjusts to move the elastic pressing cone ring 431 forward, the inner wall of the fourth synchronous wheel 447 applies a squeezing force to the elastic pressing cone ring 431, causing the elastic pressing cone ring 431 to contract and cooperate with the outer wall of the discharge pipe 41 to press the casing. This prevents meat from flowing back into the casing.

[0025] Specifically, the clamping rolling mechanism 45 includes two rollers 451 arranged opposite each other and an adjusting mechanism 452 for adjusting the distance between the two rollers 451. The two rollers 451 are respectively connected to the adjusting mechanism 452, and a space is provided between the two rollers 451 for the sausage to pass through.

[0026] In a preferred embodiment, the bottom of the material bucket 2 is provided with a water inlet pipe 40 and a water outlet pipe 50, both of which extend to the outside of the machine casing, so as to facilitate the connection of an external water pipe to clean the residue inside the material bucket.

[0027] In a preferred embodiment, the extrusion mechanism 3 includes an extrusion piston 31 and a lifting mechanism 32 for driving the extrusion piston 31 to move up and down within the material barrel 2. The extrusion piston 31 is located inside the material barrel 2, and the bottom of the extrusion piston 31 is connected to the lifting mechanism 32. The lifting mechanism 32 can be a screw jack or a ball screw jack, etc. When meat is placed in the material barrel 2, the lifting mechanism 32 drives the extrusion piston 31 to move upward, thereby squeezing the meat in the material barrel 2 and extruding it from the outlet 21. The top outer periphery of the extrusion piston 31 is provided with a downwardly inclined guide port 311, which connects to the top surface and side surface of the extrusion piston 31 and is positioned opposite to the outlet 21. When the extrusion piston 31 rises to fit the material barrel cover 6, the remaining meat in the material barrel 2 is squeezed into the guide port 311, collected and extruded through the guide port 311 to the outlet 21, making the meat in the material barrel 2 more fully extruded. In addition, in order to make the extrusion piston 31 move more smoothly up and down in the material barrel 2 and to prevent the discharge port 21 from being misaligned with the guide port 311 due to the rotation of the extrusion piston 31, a guide rod 33 is connected to the bottom of the extrusion piston 31. The guide rod 33 extends downward through the bottom of the material barrel 2 and positions and guides the extrusion piston 31.

[0028] In a preferred embodiment, the top of the material barrel 2 is also provided with a material barrel cover 6, and the material barrel cover 6 is provided with an exhaust valve 7. The exhaust valve 7 is connected to the inside of the material barrel 2. After the meat is put into the material barrel 2, the meat can be squeezed by the extrusion mechanism 3, so that the air in the meat can be discharged through the exhaust valve 7, which can play a certain role similar to vacuuming and reduce the air in the meat. Before filling, by closing the stop valve 5, a little meat is pre-pressed and discharged from the exhaust valve 7 on the material barrel cover 6, which can remove some of the remaining air in the meat, so that the meat can be tightly filled into the casing, which is convenient for the sausage to air dry. This prevents the casing from bursting due to high temperature during smoking or baking, and prevents the moisture and oil in the casing from splashing out due to the casing breaking. It also prevents moisture from remaining in the sausage for a long time and causing the sausage to spoil.

[0029] In a preferred embodiment, the side wall of the casing 1 is provided with a recessed area 11 for arranging the control panel 8 and control switch 9. The recessed area 11 is provided with a waterproof cover 10 that can be flipped open, and the upper side of the waterproof cover 10 is hinged to the upper side of the recessed area 11. After use, the enema twisting machine needs to be cleaned. During cleaning, water may splash out from the side wall of the casing 1. If water splashes onto the control panel 8 and control switch 9, it may cause a short circuit. In this embodiment, by providing a recessed area 11 on the side wall of the casing 1, the control panel 8 and control switch 9 are arranged in the recessed area 11. During cleaning, the waterproof cover 10 can prevent water from splashing into the control panel 8 and control switch 9, thus providing a better waterproof effect. In addition, when the enema twisting machine is working, the hand needs to operate the twisting process. Sometimes the hand may not be free to press the start and stop button of the control device. Therefore, the twisting machine in this embodiment is also equipped with a knee switch 20. The knee switch 20 extends out of the casing 1, and the device can be controlled by touching the knee switch 20 with the leg.

[0030] The above description is only a preferred embodiment of the present utility model. Any technical solution that achieves the purpose of the present utility model by essentially the same means shall fall within the protection scope of the present utility model.
