Description

Technical Field

[0001] This invention relates to the field of continuous feeding in continuous smoking and roasting equipment for cured meat, specifically a continuous automated smoking and roasting production line for cured meat. Background Technology

[0002] The continuous smoking and roasting equipment for cured meat generally has a long total length. Its interior is divided into: drying chamber, smoking and coloring chamber, cooking chamber and forced cooling chamber. The different chambers are set with different lengths according to the moving speed of the meat rack to meet the processing time of different steps. At the same time, the continuous production line needs to be equipped with a corresponding conveying mechanism to ensure that the meat rack moves in the continuous smoking and roasting equipment.

[0003] In the existing technology, during the operation of the device, especially when it is moved to the end of the continuous smoking device, it is not easy to separate it from the corresponding meat rack. Furthermore, when the meat rack at the prepared position is pushed into the continuous production device, it needs to be reconnected. The time loss caused by these two steps will result in a discontinuous phenomenon. Therefore, there is room for further improvement in the efficiency of continuous smoking. Summary of the Invention

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1 to 7In this embodiment of the invention, a continuous automated smoking production line for cured meat includes a U-shaped continuous smoking oven 1. The two ends of the continuous smoking oven 1 are an inlet and an outlet, respectively. A guide platform 2 is installed at the bottom of both the inlet and outlet ends of the continuous smoking oven 1. A guide plate 3 is installed on the inclined surface of the guide platform 2. The output end of the guide plate 3 is connected to a limiting guide rail 4 distributed along the bottom of the inner wall of the continuous smoking oven 1. A mounting plate 5 extending to the outside of the continuous smoking oven 1 is fixedly installed at the top of the inner wall of the continuous smoking oven 1. A transmission mechanism extending below the mounting plate 5 is installed at the top of the mounting plate 5. An outer guide rail 11 and an inner guide rail 12 extending to the outside of the continuous smoking oven 1 are respectively installed on both sides of the inner wall of the continuous smoking oven 1. The outer guide rail 11 and the inner guide rail 12 are concentrically arranged. The inner walls of the outer guide rail 11 and the inner guide rail 12 are slidably connected to a connecting frame mechanism connected to the transmission mechanism. The bottom end of the connecting frame mechanism is fixedly installed with a "U"-shaped limiting plate 24. An elastic guiding mechanism is fixedly installed between the inner walls of the two limiting plates 24. A push plate 26 is movably connected to the outer wall of the elastic guiding mechanism. A limiting cover mechanism for the push plate 26 to rotate is installed at one end of the limiting plate 24. A guide ear 30 is installed at the other end of the limiting plate 24. A reset mechanism connected to the push plate 26 and extending upward to contact the bottom ends of the outer guide rail 11 and the inner guide rail 12 is slidably connected to the inner wall of the continuous smoking oven 1. An extrusion mechanism is installed on the inner wall of the discharge port.

[0019] In this embodiment: First, the hanging rack full of cured meat to be smoked is placed at the front end of the feed inlet of the continuous smoking oven 1. The placement position should be below the straight plate of the mounting plate 5 and directly in front of the guide plate 3. When the transmission mechanism is running, it drives the connecting frame mechanism to move along the inner walls of the outer guide rail 11 and the inner guide rail 12. When the connecting frame mechanism moves to the handle position of the meat hanging rack, the connecting frame mechanism drives the two push plates 26 to push the handle position of the meat hanging rack. The meat hanging rack under force moves towards the inside of the guide plate 3. Since the two parts of the guide plate 3 are distributed in a figure-eight shape, the guide plate 3 can push the moving wheels at the bottom of the meat hanging rack to the inside of the limiting guide rail 4 during the movement of the meat hanging rack. This method can avoid the problem that the moving wheels of the meat hanging rack cannot enter the inside of the limiting guide rail 4 due to slight misalignment when the operator places the meat hanging rack in the feeding position (or the preparation position). After the hanging rack carries the cured meat suspended on it into the continuous smoking oven 1, the continuous smoking oven 1 processes the cured meat through four steps: drying, smoking, heating and maturing, and cooling and shaping. After processing, the shaped smoked cured meat moves outward from the outlet of the continuous smoking oven 1. At this time, the outer side of the push plate 26, which moves with the connecting frame mechanism, gradually approaches the inner side of the extrusion mechanism until they come into contact and generate extrusion force. Under the extrusion force, the two push plates 26 slide along the outer wall of the elastic guide mechanism and simultaneously slide along the inner side of the limiting plate 24. During this process, the limiting plate 24 restricts the push plates 26 to always be in a vertical state until the push plates 26 come into contact with the limiting cover mechanism. At this time, the push plates 26 are just offset from the two ends of the limiting plate 24. The push plates 26 are still in contact with the push handle of the hanging rack. Since the push plates 26 can rotate at this time, after the push plates 26 are offset from the limiting plate 24, the limiting cover mechanism moves with the connecting frame mechanism. Plate 24 cannot apply pushing force to the push handle of the meat rack. Instead, it will rotate into the limiting cover mechanism under the reaction force. At this time, the limiting plate 24 changes from a vertical state to an inclined state until the bottom of the push plate 26 is misaligned with the highest position of the push handle of the meat rack. At this time, the reset force of the elastic guide mechanism acts on the inclined push plate 26, and the side of the push plate 26 abuts against the inner wall of the limiting cover mechanism, restricting the push plate 26 to the current position. This can prevent the push plate 26 from rotating directly from the inclined state to the vertical state under the action of gravity when it moves from the discharge port to the inlet of the continuous smoking box. This can prevent the push plate 26 from contacting other empty meat racks or meat racks that are not intended to directly enter the continuous smoking oven 1 when it moves from the discharge port to the inlet. At the same time, during the process of the push plate 26 rotating to the inclined state, it will push the reset mechanism to move upward. When the push plate 26 moves to the position directly below the straight section of the mounting plate 5 under the drive of the connecting frame mechanism, and moves towards the meat rack placed in the preparation position, the reset mechanism is forced to move downward. During the downward movement, the reset mechanism pushes the tilted push plate 26 to the vertical position. At this time, the elastic guide mechanism resets and pushes the push plate 26 to the initial position, so that the meat rack placed in the preparation position can be pushed into the continuous smoking oven 1. The structural design of this device enables the smooth pushing of the meat rack placed in the preparation position into the continuous smoking oven 1, and automatically separates it from the meat rack after smoking. It also avoids the problem of the meat rack not being in the preparation position coming into contact with the meat rack not in the preparation position during the movement from the discharge port to the inlet port, which would cause the meat rack waiting to enter the preparation position to be moved by force, or the meat rack not in the preparation position to be moved by force, colliding with the meat rack in other positions, or even coming into contact with the meat rack in the preparation position, causing the meat rack in the preparation position to be moved out of the preparation position by force.

[0020] Please refer to this carefully. Figure 1 , Figure 2 and Figure 3 The transmission mechanism includes a drive motor 10 mounted on the top of the mounting plate 5 via a bracket and located outside the continuous smoke oven 1. The output end of the drive motor 10 is coaxially connected to a small pulley 8. The small pulley 8 is driven by a large pulley 7 via a synchronous belt 9. The bottom end of the large pulley 7 is connected to a synchronous drive wheel 6 via a synchronous shaft. The synchronous shaft is rotatably connected to the mounting plate 5 via bearings. The synchronous drive wheel 6 is located below the mounting plate 5. The transmission mechanism also includes multiple limiting wheels 13 equidistantly distributed on a "U"-shaped track. The limiting wheels 13 are driven by the mounting plate 5 via bearings. The multiple limiting wheels 13 and the synchronous drive wheel 6 are driven by a transmission belt 15. The multiple limiting wheels 13 and the synchronous drive wheel 6 cooperate to tension the transmission belt 15.

[0021] In this embodiment: During continuous production, the drive motor 10 is started, and the drive motor 10 drives the small pulley 8 to rotate. The small pulley 8 then drives the large pulley 7 to rotate synchronously through the synchronous belt 9. The large pulley 7 can then drive the synchronous drive wheel 6 to rotate. At this time, the multiple limit wheels 13 that tension the conveyor belt 15 rotate during the transmission process of the conveyor belt 15, thereby achieving the purpose of transmission of the conveyor belt 15.

[0022] Please refer to this carefully. Figure 4 The connecting frame mechanism includes a connecting frame 16 connected to the conveyor belt 15. Traction rollers 17 are fixedly installed at both ends of the bottom of the connecting frame 16. A driven roller 18 with the same structure as the traction roller 17 is provided behind the traction roller 17. Hollow connecting balls 19 are welded to the outer walls of the traction roller 17 and the driven roller 18 in opposite directions. Movable balls 20 are movably connected in the ball grooves at opposite ends of the two hollow connecting balls 19. The two movable balls 20 are fixedly connected to both ends of the connecting rod 21. The connecting frame mechanism also includes a rotating seat 41 that is rotatably connected to both ends of the traction roller 17 and the driven roller 18 around the Y-axis. A roller 22 is rotatably installed at the end of the rotating seat 41 away from the traction roller 17 and the driven roller 18 around the X-axis. The roller 22 and the rotating seat 41 distributed at both ends are located on the inner walls of the outer guide rail 11 and the inner guide rail 12, respectively. Mounting rods 23 are fixedly installed at both ends of the outer wall of the driven roller 18. The bottom end of the outer wall of the mounting rod 23 is fixedly connected to the inner wall of the arc-shaped part of the limiting plate 24.

[0023] In this embodiment: During the transmission process of the conveyor belt 15, the conveyor belt 15 drives the connecting frame 16 connected to it to move synchronously, and the connecting frame 16 pulls the bottom traction roller 17 to move synchronously. When the traction roller 17 drives the rollers 22 at both ends to rotate to the arc-shaped part of the outer guide rail 11 and the inner guide rail 12, at this time, the two ends of the traction roller 17 rotate at the same angle under the traction force, but the end located on the outer periphery moves a larger distance, while the end located on the inner periphery moves a smaller distance. At this time, the rotating seat 41 designed can avoid the opposite movement interference. Similarly, the rotating seat 41 at both ends of the driven roller 18 is designed to avoid the movement interference problem when the driven roller 18 rotates to the arc-shaped position. Meanwhile, since the traction roller 17 and the driven roller 18 are in a front-to-back position, when one moves to the arc position, the other is still in the straight position. At this time, the design of the hollow connecting ball 19 and the movable ball 20 can cause interference between the movement of the traction roller 17 and the driven roller 18.

[0024] Please refer to this carefully. Figure 4 , Figure 6 and Figure 7 The elastic guiding mechanism includes a guide rod 25 fixedly installed between two limiting plates 24 and passing through a mounting rod 23. A sliding seat 40 is slidably connected to the outer wall of the guide rod 25. The outer wall of the sliding seat 40 is rotatably connected to a push plate 26. The push plate 26 is located on the inner wall of the limiting plate 24, and the width of the push plate 26 is equal to the width of the inner wall of the limiting plate 24. A fixing ring 27 is formed near the middle position on the outer wall of the guide rod 25. A spring 38 is installed between the fixing ring 27 and the sliding seat 40. The bottom of the push plate 26 extends downward to abut against the handle of the meat-hanging cart. The limiting cover mechanism is fixedly installed on the limiting plate 24 near the end of the traction roller 17. The center of the connecting cover 28 is concentric with the center of the guide rod 25. A blocking plate 29 is formed on one side above the opening of the connecting cover 28 to restrict the continuous movement of the push plate 26 toward the center of the guide rod 25. The push plate 26 blocked by the blocking plate 29 is aligned with the opening of the connecting cover 28. The extrusion mechanism includes extrusion plates 14 fixedly installed on both sides of the inner wall of the outlet end of the continuous smoking oven 1. Multiple balls 39 are equidistantly installed on the opposite side of the two extrusion plates 14 along the trajectory of the inner side of the extrusion plates 14. The inner side of the extrusion plates 14 is inclined away from the outlet end, and the installation height of the extrusion plates 14 is greater than the maximum height of the meat hanging cart.

[0025] In this embodiment: when the connecting frame mechanism moves towards the outlet of the continuous smoke oven 1, the push plate 26 gradually approaches the inclined surface of the extrusion plate 14 until it contacts it, generating extrusion force. At this time, the two push plates 26 are forced to move along the outer wall of the guide rod 25 towards the center of the guide rod 25 until the guide rod 25 moves out from the inner side of the limiting plate 24. At this time, the guide rod 25 is located on the straight surface of the extrusion plate 14, and one side of the push plate 26 contacts the blocking plate 29. During the above process, the spring 38 is compressed. At this time, the push plate 26 and the limiting plate 24 are misaligned, and the meat rack push handle no longer has the function of... The pushing force, and the reaction force, will cause the push plate 26 to rotate. At this time, the upper part of the push plate 26 will rotate downward toward the inner wall of the connecting cover 28, and the lower part of the push plate 26 will rotate upward away from the connecting cover 28 until the lower part of the push plate 26 is misaligned with the meat rack push handle. At the same time, due to the restoring force of the spring 38 acting on the push plate 26, the push plate 26 that has completed the rotation will be tightly pressed against the inner side of the connecting cover 28. At this time, the push plate 26 cannot be reset to a vertical state under the action of gravity and remains in the current tilted state. During the above process, as the push plate 26 rotates, it drives the reset mechanism to move upward; Therefore, the cooperation between the elastic guide mechanism, the limiting cover mechanism and the push plate 26 can achieve the following: when the push plate 26 moves from the discharge port to the inlet port, it can avoid the push plate 26 from contacting any meat rack push handle that is not in the ready position, thereby ensuring the stability of the meat rack arrangement and avoiding interference problems. The sliding seat 40 is designed to prevent interference between the push plate 26 and the fixed end of the spring 38 when the push plate 26 rotates, which could cause the push plate 26 to rotate poorly or be reset by the twisted spring 38 after rotation.

[0026] Please refer to this carefully. Figure 4 , Figure 5 and Figure 7 The reset mechanism includes a push rod 32 that slides vertically and vertically connected to the inner wall of the guide ear 30. A connecting strip 33 is fixedly installed at the top of the vertical part of the push rod 32. An upwardly extending pressure plate 34 is fixedly installed at the top of the connecting strip 33. The top of the pressure plate 34 has an arc-shaped structure. A pressure plate 35 is installed at the bottom of the outer guide rail 11 and the inner guide rail 12 in front of the feed inlet of the continuous smoke oven 1. The bottom end of the pressure plate 35 is formed with a pressing slope that abuts against the arc-shaped surface of the pressure plate 34. The reset mechanism also includes a protruding plate 31 fixedly installed at the bottom of the inner side of the push plate 26. An outwardly protruding follower plate 36 is formed on the inner side of the protruding plate 31. A vertical groove 37 is vertically opened on the follower plate 36. The horizontal part of the push rod 32 is movably connected to the inner wall of the vertical groove 37.

[0027] In this embodiment: when the upper half of the push plate 26 rotates downward toward the inner wall of the connecting cover 28, the bottom of the push plate 26 drives the protruding plate 31 to rotate upward synchronously. The protruding plate 31 then drives the follower plate 36 to rotate upward. During the rotation, the inner wall of the vertical groove 37 on the follower plate 36 applies an upward thrust to the horizontal part of the push rod 32. The force on the horizontal part of the push rod 32 will drive the two vertical parts of the push rod 32 to move upward synchronously. The top of the vertical part of the push rod 32 will push the connecting strip 33 upward. The connecting strip 33 will then drive the pressure plate 34 to move upward to the highest position. Since the vertical groove 37 is movably connected to the push rod 32, the problem of axial movement of the push rod 32 caused by the movement of the follower plate 36 can be avoided. Until the push plate 26 rotates to the front end of the feed inlet of the continuous smoke oven 1 and is located at the straight plate part of the mounting plate 5, the top arc-shaped surface of the pressure plate 34, which is moving linearly, will contact the extrusion slope of the pressure plate 35. Since the position of the pressure plate 35 is fixed, the pressure generated by the extrusion will cause the pressure plate 34 to move downward. The pressure plate 34 will then drive the push rod 32 to return downward through the connecting strip 33 connected to it. At this time, the push rod 32 will apply a downward thrust to the vertical groove 37. At this time, the vertical groove 37 will be pushed downward through the follower plate 36 and the protrusion. The ejector plate 31 drives the push plate 26 to rotate to a vertical position. At this time, the highest point of the pressure plate 34 is aligned with the lowest point of the pressure plate 35, and the two no longer contact and squeeze each other. At this time, the push plate 26 contacts the bottom end of the opening of the connecting cover 28, restricting the push plate 26 to remain in a vertical position. At this time, the spring 38 can reset and drive the push plate 26 to reset to the inside of the limit plate 24. The push plate 26, which cannot rotate, has sufficient pushing force. At this time, the push plate 26 can push the meat rack push handle placed in the preparation position into the interior of the continuous smoking oven 1.
