Description

Technical Field

[0001] This invention relates to the field of raw material addition technology, and more specifically, to a raw material addition mechanism for the production of canned pork small intestine. Background Technology

[0002] In existing technologies for adding raw materials in the production of canned pork small intestines, traditional production processes suffer from significant intermittent operation and production efficiency bottlenecks. This restricts the continuity and economic benefits of large-scale industrial production of canned food. With existing technology, after completing one round of raw material addition, the entire production system must stop, waiting for workers or automated equipment to remove the canned products from the addition station and transfer them to the next process. This intermittent production mode of downtime and waiting compresses the effective working time of the equipment, affecting the production cycle. Each stop not only wastes valuable production time but also leads to frequent equipment start-ups and shutdowns, increasing the load and wear on the motors and transmission systems. Furthermore, operators need to perform repetitive handling and positioning operations in each production cycle, increasing labor intensity and making them prone to operational errors and product quality fluctuations due to human factors.

[0003] The traditional single-station, intermittent operation of the additive mechanism results in low additive efficiency for the entire production line, failing to meet the urgent needs of the modern food industry for high-efficiency, large-scale, and continuous production. In actual production, the downtime of the additive mechanism often accounts for a large proportion of the entire production cycle, leading to insufficient equipment utilization. At the same time, intermittent production also makes it difficult to control the temperature of raw materials during the additive process. During downtime, the raw materials may experience temperature changes or quality deterioration, affecting the taste and shelf life of the final product. Frequent start-up and shutdown operations also increase the risk of equipment failure, and maintenance costs and downtime losses increase accordingly. Summary of the Invention

[0004] (a) Technical problems to be solved To address the problems existing in the prior art, the present invention provides a raw material addition mechanism for canned pork small intestine food production, thereby solving the technical problems mentioned in the background art.

[0005] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a raw material addition mechanism for canned pork small intestine, comprising a feeding pipe, a spiral conveying rod rotatably connected inside the feeding pipe, a motor provided on one side of the feeding pipe, the output end of the motor being fixedly connected to one end of the spiral conveying rod, and an inlet pipe provided on the side wall of the feeding pipe; further comprising an injection mechanism, wherein two sets of the injection mechanism are symmetrically arranged about the feeding pipe, each comprising a protective shell, a flexible tube inside the protective shell, and an extrusion ring rotatably connected inside the protective shell, the extrusion ring abutting against the surface of the flexible tube; and further comprising a start-stop mechanism, wherein two sets of the start-stop mechanism are symmetrically arranged about the feeding pipe, each comprising a push rod, the push rod being connected to a push spring.

[0006] Preferably, the outer surface of the feeding pipe is connected to a mounting frame, the side wall of the mounting frame is provided with two sets of sleeves, the two ends of the mounting frame are provided with two sets of mounting sleeves, and the two sides of the feeding pipe are connected to two sets of discharge pipes. As the core support structure of the entire adding mechanism, the mounting frame provides a stable mechanical foundation and spatial positioning reference for the whole equipment through its firm connection with the outer surface of the feeding pipe.

[0007] Preferably, one end of the hose is connected to the discharge pipe, and the other end is connected to the feed pipe. The protective shell is located at both ends of the mounting frame. The hose serves as a flexible channel for transporting raw materials. The sealed connection between one end of the hose and the discharge pipe ensures a smooth transition of the raw materials from the rigid pipe to the flexible pipe. The connection between the other end of the hose and the feed pipe enables precise directional delivery of the raw materials to the can.

[0008] Preferably, the extrusion ring has a trapezoidal block on one side and a connecting rod on the other side. The connecting rod passes through the mounting sleeve and is rotatably connected to the mounting sleeve. A ratchet is connected to the other end of the connecting rod, and a drive wheel is engaged on the outside of the ratchet. As the core actuator for material injection control, the extrusion ring controls the flow of raw materials and regulates the flow rate by tightly contacting the surface of the hose.

[0009] Preferably, a rotating rod is rotatably connected to the center of the mounting bracket, a driven wheel is sleeved on the surface of the rotating rod, the driven wheel and the drive wheels on both sides are connected by belts, and a circular plate is connected to the other end of the rotating rod. The circular plate serves as a generator of control signals, and its fixed connection with the rotating rod converts the continuous rotational motion into the periodic signals required for control.

[0010] Preferably, the sidewall of the circular plate is hinged with a first hinge rod and a second hinge rod, and the other ends of the first hinge rod and the second hinge rod are respectively hinged to the push rods in the start-stop mechanism on both sides of the feeding tube. The first hinge rod and the second hinge rod realize the mechanical conversion from rotational motion to reciprocating linear motion through the hinged connection of the sidewall of the circular plate.

[0011] Preferably, the push rod is inserted into the sleeve and slidably connected to the sleeve. The sleeve is provided with a ring spring, which provides a stable elastic restoring force and bistable positioning function for the locking mechanism.

[0012] Preferably, the other end of the push spring is connected to a limiting ring, and the other side of the limiting ring is connected to a locking ball adapted to the ring spring. One side of the locking ball abuts against the ring spring. As the core element of the bistable locking, the locking ball's adaptation design with the ring spring enables reliable locking and smooth switching between two stable positions.

[0013] Preferably, the sleeve sidewall is connected to a right-angle tube, the other end of the right-angle tube is connected to the sidewall of the protective shell, a right-angle spring is provided inside the right-angle tube, and the other end of the locking ball is connected to the right-angle spring. The change in the position of the locking ball can be accurately transmitted to the right-angle spring and generate a corresponding locking or unlocking action. The right-angle spring amplifies the displacement signal of the locking ball through elastic deformation and converts it into sufficient locking force.

[0014] Preferably, the other end of the right-angle spring is connected to a retaining sleeve, which is slidably connected to the right-angle tube. The retaining sleeve is adapted to the trapezoidal block on the side wall of the extrusion ring. The retaining sleeve and the trapezoidal block are designed to lock or unlock the injection mechanism.

[0015] (III) Beneficial Effects Compared with existing technologies, this invention provides a raw material addition mechanism for canned pork intestines, which has the following advantages: This raw material addition mechanism for canned pork intestines solves the efficiency bottleneck problem of traditional single-station intermittent production by using a dual-set injection mechanism alternating working design and a start-stop control system. It achieves continuous and efficient raw material addition. The device uses a continuous feeding system driven by a screw conveyor rod in conjunction with symmetrically arranged dual-set injection mechanisms. This allows the injection mechanism on one side to work normally and add raw materials to the can while the injection mechanism on the other side is in a stopped state waiting for the can to be replaced. When one side finishes adding materials, it switches to a stopped state, while the other side immediately starts adding materials, forming an alternating and cyclical continuous production mode. This eliminates the downtime waiting time in traditional technologies and improves equipment utilization.

[0016] The design of the extrusion ring and hose achieves an organic combination of raw material flow and injection control. The thrust of the raw material flow in the hose directly drives the extrusion ring to rotate. The injection status signal is transmitted to the entire control system through the connecting rod and ratchet mechanism. The one-way meshing design of the ratchet and drive wheel ensures that the drive system can continue to operate even if one side of the injection mechanism stops working. The belt drive system realizes the coordinated control of the two injection mechanisms, ensuring the continuity and stability of the system operation. The crank-connecting rod mechanism of the circular plate with the first and second hinge rods converts the continuous rotational motion into reciprocating linear motion, providing control signals and power sources for the start and stop mechanism, and realizing the timing control and automatic switching of the two injection mechanisms.

[0017] The bistable locking mechanism, composed of a push rod, push spring, locking ball, and ring spring, is reliable. The stable locking of the locking ball on both sides of the ring spring ensures accurate control of the start and stop states, avoiding uncertainty in intermediate states. The snap-fit ​​design between the right-angle spring and the sleeve and the trapezoidal block enables reliable locking and rapid release of the extrusion ring. The special geometry of the trapezoidal block provides good self-locking performance and convenient unlocking operation. This mechanical control system can achieve accurate timing control without complex electronic control components, and has the advantages of simple structure, high reliability, and convenient maintenance.

[0018] The entire feeding mechanism, through its dual-station alternating operation design, allows the production line to simultaneously add raw materials at one station while the other station performs can replacement and cleaning preparations, achieving continuous production. Compared to traditional intermittent feeding methods, this improves production efficiency, reduces unit product production costs and energy consumption, and ensures stable raw material temperatures and consistent product quality. It also reduces the impact and wear on equipment caused by frequent start-ups and shutdowns, extends equipment lifespan, and lowers maintenance costs. This mechanism reduces the number of manual operation steps and the intensity of manual labor, lowers the risk of operational errors due to human factors, and improves product quality stability and production safety. This dual-station alternating raw material feeding mechanism solves the core problem of low feeding efficiency in traditional technologies, providing a reliable technical solution for the large-scale, continuous production of canned pork small intestines.

A drive wheel 28 is engaged on the outside of the ratchet 27. A rotating rod 19 is rotatably connected at the center of the mounting frame 15. A driven wheel 110 is sleeved on the surface of the rotating rod 19. The driven wheel 110 and the drive wheels 28 on both sides are connected by a belt 111. The other end of the rotating rod 19 is connected to a circular plate 112. It also includes a start-stop mechanism, which has two sets of start-stop mechanisms symmetrically arranged about the feeding pipe 11. Each start-stop mechanism includes a push rod 31, with a push spring 32 connected inside the push rod 31. A first hinge rod 33 and a second hinge rod 34 are hinged to the side wall of the circular plate 112. The other ends of the first hinge rod 33 and the second hinge rod 34 are respectively hinged to the push rod 31 in the start-stop mechanism on both sides of the feeding pipe 11. The push rod 31 is inserted into the sleeve 16 and slidably connected to the sleeve 16. A ring spring 35 is provided inside the sleeve 16, and the other end of the push spring 32 is connected to a limit switch. Ring 36, the other side of the limiting ring 36 is connected to a retaining ball 37 adapted to the annular spring 35. One side of the retaining ball 37 abuts against the annular spring 35. The side wall of the sleeve 16 is connected to a right angle tube 38. The other end of the right angle tube 38 is connected to the side wall of the protective shell 21. A right angle spring 39 is provided inside the right angle tube 38. The other end of the retaining ball 37 is connected to the right angle spring 39. The other end of the right angle spring 39 is connected to a retaining sleeve 310. The retaining sleeve 310 is slidably connected to the right angle tube 38. The retaining sleeve 310 is adapted to the trapezoidal block 25 on the side wall of the extrusion ring 23.

[0025] First, the raw material to be added is connected to the feed pipe 14. The raw material is injected into the feeding pipe 11 through the feed pipe 14. The motor 13 starts and drives the screw conveyor 12 to rotate. The screw conveyor 12 conveys the raw material injected into the feeding pipe 11 forward. The raw material is pushed and enters the hose 22 through the discharge pipe 18 on one side. When the raw material flows through the hose 22, it pushes the extrusion ring 23 to rotate. Then, it is injected into the empty can placed below through the discharge pipe 24. The rotation of the extrusion ring 23 drives the connecting rod 26 to rotate synchronously. The rotation of the connecting rod 26 drives the ratchet 27 to rotate. The drive wheel 28, which meshes with the ratchet 27, rotates accordingly. The rotation of one drive wheel 28 drives the driven wheel 110 and the other drive wheel 28 to rotate via the belt 111. The rotation of the driven wheel 110 drives the circular plate 112 to rotate via the rotating rod 19. The first hinge rod 33 and the second hinge rod 34 move with the rotation of the circular plate 112. The movement of the first hinge rod 33 and the second hinge rod 34 will drive the push rod 31, which is hinged to them, to slide along the sleeve 16. The first hinge rod 33 and the second hinge rod 34 reciprocate with the rotation of the circular plate 112. When the first hinge rod 33 rotates to the position closest to the injection mechanism on one side, it generates the maximum thrust on the push rod 31 connected to it. The push spring 32 at the other end of the push rod 31 is pushed forward by the thrust, which in turn pushes the locking ball 37 to overcome the elastic force of the ring spring 35 and move to the other side of the ring spring 35. At this time, the other side of the locking ball 37 abuts against the ring spring 35, and the other end of the locking ball 37 pushes the right angle spring 39 together with the sleeve 310 to engage with the trapezoidal block 25 on the side wall of the extrusion ring 23. At this time, the extrusion ring 23 is locked and can no longer rotate, and the injection mechanism on this side can no longer inject material. The ratchet 27 corresponding to the extrusion ring 23 on this side stops rotating. Because the direction of rotation of the drive wheel 28 is always in one direction, the ratchet 27 on one side stops rotating, but this does not prevent the drive wheel 28 meshing with it from continuing to be driven by the drive wheel 28 on the other side through the belt 111. The two sets of drive wheels 28 and driven wheels 110 are constantly rotating, and the circular plate 112 is also constantly rotating. At the same time, the injection mechanism on one side of the second hinge rod 34 is in the open state. When the first hinge rod 33 generates the maximum thrust on the push rod 31 connected to its hinge, the second hinge rod 34 generates the maximum pull on the push rod 31 connected to its hinge. The second hinge rod 34 pulls the push rod 31 on one side to slide along the sleeve 16. The push rod 31 drives the push spring 32 to move. The push spring 32 drives the ball 37 to move synchronously through the limit ring 36. The ball 37 is pulled to the other side of the ring spring 35, which in turn pulls the right angle spring 39 and the sleeve 310 to move backward, releasing the sleeve 310 from the trapezoidal block 25. The extrusion ring 23 can rotate, and the raw material pushes the extrusion ring 23 to rotate through the hose 22 and is injected into the empty can below through the discharge pipe 24. The first hinge rod 33 and the second hinge rod 34 continue to rotate with the circular plate 112. When the second hinge rod 34 rotates to the position closest to the filling mechanism on one side, it generates the maximum thrust on the push rod 31 connected to it. The push rod 31 pushes the push spring 32 and the locking ball 37 forward. The locking ball 37 overcomes the elastic force of the ring spring 35 and moves to the other side of the ring spring 35, pushing the right-angle spring 39 together with the sleeve 310 to engage with the trapezoidal block 25 of the extrusion ring 23 on this side, causing the extrusion ring 23 on this side to stop rotating and thus stop filling. At this time, the canned goods filled on this side can be collected. At the same time, when the second hinge rod 34 pushes the push rod 31 connected to it... When rod 31 generates the maximum thrust, the first hinge rod 33 generates the maximum pull on the push rod 31 that is hinged to it. The push rod 31 pulls the push spring 32 and the locking ball 37 to move backward. The locking ball 37 overcomes the elastic force of the ring spring 35 and returns to the other side of the ring spring 35. The locking ball 37 drives the right angle spring 39 and the sleeve 310 to move backward, releasing the locking and fixing of the extrusion ring 23 on this side. At this time, the raw material can push the extrusion ring 23 to rotate and then be injected into the empty can on this side through the feed pipe 24. At this point, the circular plate 112 has rotated one revolution, and the first hinge rod 33 and the second hinge rod 34 reciprocate, so that when raw material is being added on one side, the feeding mechanism on the other side is in a stopped state.
