Description

Technical Field

[0001] This invention relates to the field of food processing technology, specifically to a device for uniformly coating raw meat with powder. Background Technology

[0002] As is widely known in the food processing industry, some pre-made foods, such as popcorn chicken and chicken cutlets, need to be coated with flour after marinating. The main purpose of coating with flour is to enhance the flavor and taste of the raw meat. By adding various spices and seasonings, the meat can be made more delicious and diverse.

[0003] Currently available powder coating equipment suffers from problems such as severe slurry loss, long coating time, uneven coating, easy sticking of wet powder, and incomplete powder return leading to significant powder waste. These issues not only affect the final quality of fried products but also reduce production efficiency and increase production costs. Therefore, existing technologies address this problem by designing a powder coating mechanism, as exemplified by the invention patent CN108402501B, published on July 28, 2023, entitled "A Raw Meat Roller Powder Coating Device." This device includes a frame, a feeding conveyor system, a roller powder coating system, a vibrating discharge conveyor system, and a residual powder recovery system. The feeding conveyor system, roller powder coating system, and vibrating discharge conveyor system are sequentially installed from left to right on the top of the frame. The residual powder recovery system is installed on the front side of the frame, and multiple sets of casters are symmetrically installed on the bottom of the frame. Due to the adoption of the above technical solution, the beneficial effects of the present invention are as follows: the present invention has less slurry loss, shorter powder coating time, more uniform powder coating, less sticking of wet powder, more thorough powder return and less powder waste, which not only ensures the final quality of fried products, but also improves production efficiency and reduces production costs.

[0004] The shortcoming of the existing technology is that when using a roller powdering system to powder strips or small pieces of raw meat, the raw meat can roll with the roller to achieve the purpose of powdering. However, when powdering larger pieces of raw meat (similar to slices of raw meat), relative sliding may occur between the raw meat and the roller, or the raw meat may pile up after falling due to gravity after rotating with the roller. Obviously, this will inevitably lead to uneven powdering of the raw meat. Summary of the Invention

[0005] The purpose of this invention is to provide a device for uniformly coating raw meat with powder, thereby solving the technical problems in related technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A raw meat homogenization powder coating device includes a frame and a cylinder mounted on the frame. The cylinder is filled with raw meat powder. It also includes a sieve cylinder and a first driving member that drives the sieve cylinder to rotate within the cylinder. A sieve plate is provided inside the sieve cylinder, and the sieve plate rotates synchronously with the sieve cylinder. A second driving member is provided on the cylinder to control the distance between the sieve plate and the inner wall of the sieve cylinder. When coating the raw meat with powder, the process includes two strokes: In the first stroke, the second driving member drives the sieve plate to approach the inner wall of the sieve cylinder to clamp the raw meat, and the first driving member drives the sieve cylinder to rotate half a revolution to flip the raw meat; In the second stroke, along the direction where the sieve plate approached the inner wall of the sieve cylinder during the first stroke, the second driving member drives the sieve plate to approach the inner wall of the sieve cylinder to release the clamping of the raw meat, and the first driving member drives the sieve cylinder to rotate half a revolution.

[0008] As described above, the sieve cylinder consists of two rings arranged at both ends of the axial direction and columnar spiral ribs arranged between the two rings. Multiple straight ribs parallel to the axial direction are arranged between the two rings. The multiple straight ribs are evenly arranged in the circumferential direction, and each straight rib is fixedly connected to the spiral rib. In the second stroke, the spiral rib gives the raw meat a thrust to move along the axial direction.

[0009] As mentioned above, the cylinder is arranged at an angle, and the inlet height of the raw meat is lower than the outlet height of the raw meat after powdering.

[0010] As mentioned above, in the direction in which the raw meat is pushed by the spiral tendons, the amount of raw powder in the screen cylinder gradually decreases.

[0011] As described above, the sieve plate consists of two first rods arranged at both ends in the axial direction and a plurality of ribs parallel to the axial direction arranged between the two first rods. The plurality of ribs are arranged sequentially along the trajectory of the first rods.

[0012] As mentioned above, the first rod can switch between a straight line shape and an arc shape under the action of external force.

[0013] As described above, each ring corresponds to a first rod, and each ring is rotatably provided with two columnar blocks. A second rod is slidably provided on a certain radial direction of the columnar blocks. The two ends of the first rod are respectively hinged to the two second rods at corresponding positions. A slider is provided at the end of the second rod away from the first rod. The cylinder is provided with an annular groove, and the slider is slidably connected to the annular groove. The second driving member pushes the slider away from the annular groove, so that the first rod changes from an arc shape to a straight shape. The second driving member pushes the slider into the annular groove, so that the first rod changes from a straight shape to an arc shape.

[0014] As described above, multiple protrusions are arranged on the first rod along its trajectory direction, and the overall thickness of the first rod and the protrusions is less than the thickness of the second rod; during the stroke in which the first rod is driven by the second rod to contact the columnar block, the multiple protrusions are successively squeezed by the columnar block to generate vibration.

[0015] The second driving component described above includes multiple grooves formed on the cylinder, with each slider corresponding to one groove, and each groove being divided into a first segment and a second segment; it also includes a turntable and a third rod slidably disposed in a certain radial direction of the turntable, and an elastic element is provided between the third rod and the turntable in the sliding direction; during the rotation stroke of the turntable driving the third rod, when the third rod pushes the slider to move in the first segment, the first rod changes from an arc shape to a straight shape, and when the third rod pushes the slider to move in the second segment, the first rod changes from a straight shape to an arc shape.

[0016] As described above, the first segment gradually becomes shallower in the axial direction along the direction away from the annular groove, and the axial depth of the end of the first segment near the annular groove is shallower than the depth of the annular groove. The second segment gradually becomes shallower in the axial direction along the direction near the annular groove. The depth of the end of the first segment away from the annular groove is deeper than the depth of the end of the second segment away from the annular groove.

[0017] The beneficial effects of the present invention are as follows: the second driving member drives the sieve plate to approach the inner wall of the sieve cylinder to clamp the raw meat, and the first driving member drives the sieve cylinder to rotate half a turn to flip the raw meat. When the sieve cylinder rotates, relative sliding between the raw meat and the inner wall of the sieve cylinder can be avoided, and the raw meat will not fall and pile up due to gravity, thereby improving the powdering effect of the raw meat.

[0026] To enable those skilled in the art to better understand the technical solution of the present invention, the following will be described in conjunction with the appendix. Figure 1 To be continued Figure 5 The present invention will now be described in further detail.

[0027] This invention provides a raw meat uniform powdering device, including a frame 1 and a cylinder 2 disposed on the frame 1. The cylinder 2 is filled with raw meat powder. It also includes a sieve cylinder 3 and a first driving member that drives the sieve cylinder 3 to rotate inside the cylinder 2. The sieve cylinder 3 is provided with a sieve plate 4, which rotates synchronously with the sieve cylinder 3. The cylinder 2 is provided with a second driving member 5 that controls the distance between the sieve plate 4 and the inner wall of the sieve cylinder 3. When powdering the raw meat, there are two strokes: In the first stroke, the second driving member 5 drives the sieve plate 4 to approach the inner wall of the sieve cylinder 3 to clamp the raw meat, and the first driving member drives the sieve cylinder 3 to rotate half a turn to flip the raw meat; In the second stroke, along the direction in which the sieve plate 4 approaches the inner wall of the sieve cylinder 3 during the first stroke, the second driving member 5 drives the sieve plate 4 to approach the inner wall of the sieve cylinder 3 to remove the clamping of the raw meat, and the first driving member drives the sieve cylinder 3 to rotate half a turn.

[0028] Specifically, cylinder 2 is mounted on frame 1. The bottom of its interior stores the raw meat powder for coating. This powder is a consumable, so a powder replenishment mechanism can be installed as needed. This powder replenishment mechanism is existing technology and will not be described in detail. One axial end of cylinder 2 is the raw meat inlet 20, and the other end is the outlet 21 after coating. A conveying mechanism can be installed at inlet 20 to feed the raw meat into cylinder 2 one by one for coating. This conveying mechanism is existing technology and will not be described in detail. A mechanism for further processing of the coated raw meat, such as a retrieval mechanism, can be installed at outlet 21. The existing technology will not be elaborated here. In the existing technology, the cylinder 2 is rolled on the frame 1 and is driven by a drive unit to move in a circumferential direction. The raw meat is powdered by rolling. This powdering method is suitable for powdering strips or small pieces of raw meat. The raw meat can roll with the cylinder to achieve the purpose of powdering. However, when powdering larger pieces of raw meat (similar to slices of raw meat), relative sliding will occur between the raw meat and the cylinder, or the raw meat will pile up after falling due to gravity after rotating with the cylinder. This will inevitably lead to uneven powdering of the raw meat.

[0029] Therefore, based on the above problems, in this embodiment, the cylinder 2 is fixed to the frame 1, and a sieve cylinder 3 is rotatably installed inside the cylinder 2. The sieve cylinder 3 is made by rolling a sieve plate 4 into a cylindrical shape. It is driven to rotate inside the cylinder 2 by a first driving member. The first driving member can be a motor that drives the sieve cylinder 3 to rotate through a gear transmission mechanism. When the raw meat enters the cylinder 2, it is on the sieve cylinder 3. There is a certain space 58 between the outer wall of the sieve cylinder 3 and the inner wall of the cylinder 2. Therefore, the amount of raw material powder filling in the cylinder 2 should be sufficient to cover the raw meat. After the raw meat is placed in the sieve cylinder 3, it is on the raw material powder and does not contact the inner wall of the sieve cylinder 3. Therefore, it is difficult for the sieve cylinder 3 to move the raw meat together when it rotates. Therefore, in this embodiment, a sieve plate 4 is installed inside the sieve cylinder 3. The sieve plate 4 can be an ordinary mesh sieve plate 4. The sieve cylinder 3 is driven by the second driving member 5 to move closer to the inner wall of the sieve cylinder 3 in a certain direction. That is, when the raw meat enters the cylinder 2, it is in a position close to the bottom of the cylinder 2. Then the sieve plate 4 should be driven by the second driving member 5. The second drive component 5 moves towards the bottom of the cylinder 2, and then works with the inner wall of the screen cylinder 3 to clamp the raw meat. When the screen cylinder 3 is rotated by the first drive component, the raw meat can rotate with it. When the screen cylinder 3 rotates half a turn, it can turn the raw meat over. At this time, the raw meat is supported by the screen plate 4. Then the second drive component 5 drives the screen plate 4 to move vertically downward towards the bottom of the cylinder 2. The raw meat moves down with the screen plate 4. During the contact with the raw powder and the subsequent stroke, the raw meat will gradually be supported by the raw powder and detach from the screen plate 4. Then the first drive component drives the screen cylinder 3 to rotate half a turn, and then repeats the above process to turn the raw meat over. After the raw meat is turned over multiple times, the powder coating effect can be effectively improved. The second drive component 5 drives the screen plate 4 to move vertically. It can be a linear motion mechanism, such as a cylinder or an electric push rod. After the raw meat is coated with powder, it can be taken out by the picking mechanism and sent to the frying equipment.

[0030] The beneficial effects of this embodiment are as follows: First, by driving the sieve plate 4 close to the inner wall of the sieve cylinder 3 with the second driving member 5 to clamp the raw meat, and by driving the sieve cylinder 3 to rotate half a turn to turn the raw meat over, relative sliding between the raw meat and the inner wall of the sieve cylinder 3 can be avoided when the sieve cylinder 3 rotates, and the raw meat will not fall and pile up due to gravity. Second, when the raw meat is supported by the raw powder after being turned over, during the process of the sieve plate 4 being driven by the sieve cylinder 3 to rotate half a turn, when the sieve plate 4 detaches from the bottom of the raw meat, it pushes and loosens the raw powder below the raw meat. In this way, the raw meat will sink into the raw powder a certain distance under the influence of gravity, and the raw powder on the side of the raw meat will come into contact with the side of the raw meat, thus completing the powdering of the side of the raw meat.

[0031] Preferably, the screen cylinder 3 is composed of two rings 30 arranged at both ends of the axial direction and columnar spiral ribs 31 arranged between the two rings 30. A plurality of straight ribs 32 parallel to the axial direction are arranged between the two rings 30. The plurality of straight ribs 32 are evenly arranged in the circumferential direction, and each straight rib 32 is fixedly connected to the spiral rib 31. In the second stroke, the spiral rib 31 provides the raw meat with a thrust to move along the axial direction.

[0032] Specifically, in the aforementioned embodiments, the raw meat remains essentially in one position within the cylinder 2 during the powdering process. Depending on the length of the cylinder 2, multiple pieces of raw meat can be placed at once. After the raw meat is powdered within the cylinder 2, a picking mechanism is needed. In this embodiment, the sieve cylinder 3 is composed of columnar spiral ribs 31 and multiple straight ribs 32. This ensures that the raw meat within the sieve cylinder 3 can contact the powder while also providing an axial thrust to the raw meat during rotation. That is, the two rings 30 are arranged rotatably at both ends of the cylinder 2's axial direction and are driven to rotate by the first driving member. In the second stroke, the raw meat is supported by the raw powder. During the half-turn rotation of the screen plate 4 and the screen cylinder 3, the rotation of the columnar spiral ribs 31 gives the raw powder an axial thrust (similar to the conveying principle of the spiral conveyor mechanism). The direction of this force is from the raw meat inlet 20 of the cylinder 2 to the outlet 21. The movement of the raw powder drives the raw meat to move together. In this way, the frying equipment can be set at the outlet 21 of the cylinder 2, which can eliminate the need for a picking mechanism. When the distance between the previous piece of raw meat and the inlet 20 is suitable for the next piece of raw meat to enter the cylinder 2, the conveying mechanism can send the next piece of raw meat into the cylinder 2 for powder coating.

[0033] Furthermore, the cylinder 2 is arranged at an angle, and the height of the raw meat inlet 20 is lower than the height of the raw meat outlet 21 after powdering.

[0034] Specifically, during the rotation of the columnar spiral ribs 31, an axial thrust is applied to the raw material powder, causing the powder to concentrate at the outlet 21. Therefore, the cylinder 2 is arranged at an angle, with the height of the inlet 20 lower than the height of the outlet 21. The raw material powder pushed towards the outlet 21 can also slide towards the inlet 20 under the influence of gravity along the tilting direction of the cylinder 2. The amount of raw material powder near the outlet 21 should be less than that near the inlet 20. Therefore, in the direction in which the raw meat is pushed by the spiral ribs 31, the amount of raw material powder in the sieve cylinder 3 gradually decreases. That is, the process of powdering the raw meat in the cylinder 2 is divided into a powdering stage and a residual powder recovery stage. If there is raw material powder in the half of the sieve cylinder 3 near the inlet 20 and no raw material powder in the half near the outlet 21, then powdering is performed first during the movement of the raw meat. After powdering is completed, the excess powder can fall back into the cylinder 2 after the part without raw material powder is turned over, thus avoiding waste of raw material powder.

[0035] Preferably, the sieve plate 4 consists of two first rods 40 arranged at both ends in the axial direction and a plurality of ribs 41 parallel to the axial direction arranged between the two first rods 40, with the plurality of ribs 41 arranged sequentially along the trajectory of the first rods 40.

[0036] Specifically, in the aforementioned embodiments, the movement of raw meat within the cylinder 2 is divided into a powdering stage and a residual powder recovery stage. During the residual powder recovery stage, since this part of the sieve cylinder 3 has no raw meat powder, the flipped raw meat continues to be supported by the sieve plate 4. Therefore, when the sieve plate 4 rotates half a revolution with the sieve cylinder 3, the raw meat cannot move with the sieve plate 4. Thus, in this embodiment, the part of the sieve plate 4 that contacts the raw meat is composed of multiple axially parallel pressure ribs 41. Since the sieve cylinder 3 can provide axial thrust to the raw meat, in the remaining... In terms of direction, the sieve cylinder 3 provides resistance to the raw material powder. When the pressing strip 41 presses the raw meat against the inner wall of the sieve cylinder 3, it utilizes the resistance of the sieve cylinder 3 to prevent the raw meat from sliding. When the raw meat is supported by the sieve plate 4, it does not contact the inner wall of the sieve cylinder 3, so there can be relative movement between the raw meat and the sieve plate 4. Furthermore, the pressing strip 41 can be rotatably set on the first rod 40. In this way, when the sieve plate 4 rotates with the sieve cylinder 3, it is easier for the pressing strip 41 and the raw meat to move relative to each other, thus preventing the raw meat from moving with the sieve plate 4.

[0037] Furthermore, the first rod 40 can switch between a straight line shape and an arc shape under external force. Specifically, during the process of pressing and turning the raw meat, the raw meat should be prevented from folding. Therefore, when pressing the raw meat, the shape of the sieve plate 4 should become an arc shape close to the concentricity of the sieve cylinder 3. Then, when the second driving member 5 drives the sieve plate 4 to approach the inner wall of the sieve cylinder 3, it should also control the sieve plate 4 to become an arc shape. In the preferred embodiment, each ring 30 corresponds to one first rod 40, and each ring 30 is rotatably provided with two columnar blocks 50. A second rod 51 is slidably provided on a certain radial direction of the first rod 40. The second rod 51 is non-deformable. The two ends of the first rod 40 are respectively hinged to the two second rods 51 at corresponding positions. A slider 52 is provided at the end of the second rod 51 away from the first rod 40. An annular groove 53 is provided on the cylinder 2. The slider 52 is slidably connected to the annular groove 53. The second driving member 5 pushes the slider 52 away from the annular groove 53, so that the first rod 40 changes from an arc shape to a straight shape. The second driving member 5 pushes the slider 52 into the annular groove 53, so that the first rod 40 changes from a straight shape to an arc shape.

[0038] When the raw meat is placed into the sieve cylinder 3, the sieve plate 4 is in a straight line. Then, the second driving member 5 exerts a force on the second rods 51 located at both ends of the same first rod 40, causing the two second rods 51 to move closer together. During this process, the end of the second rod 51 furthest from the first rod 40 should also bend upwards to apply a downward force to the first rod 40, allowing it to bend in a specific direction. During this bending process, the pressure strips 41 gradually press the raw meat against the inner wall of the sieve cylinder 3. Then, the first driving member drives the sieve cylinder 3 to rotate half a revolution. During this process, the second driving member 5 does not affect the rotation of the sieve plate 4. After the raw meat is turned over, the sieve plate 4 needs to move downwards and bend towards the bottom of the cylinder 2 to fit close to the inner wall of the sieve cylinder 3. At this time, the second driving member 5 exerts a force on the second rods 51 located at both ends of the same first rod 40, causing the two second rods 51 to move closer together. As the bodies 51 move away from each other, the sieve plate 4 changes from an arc shape to a straight shape, and then back to an arc shape. Therefore, after the sieve plate 4 becomes straight, the second driving member 5 exerts a force on the second rods 51 located at both ends of the same first rod 40, causing the two second rods 51 to move closer to each other. During the process of the two second rods 51 moving closer to each other, the end of the second rod 51 away from the first rod 40 should also bend upward to give the first rod 40 a downward force, causing the first rod 40 to bend in a specific direction until the first rod 40 is close to the inner wall of the sieve cylinder 3 and becomes an arc shape. During the above process, the columnar block 50 can adapt to the change in the swing angle of the second rod 51. The annular groove 53 is used when the sieve cylinder 3 drives the sieve plate 4 to rotate. The slider 52 slides in the annular groove 53. The slider 52 is restricted by the annular groove 53, and the bending angle of the first rod 40 is not easily changed due to the gravity of the raw meat.

[0039] Preferably, the second driving member 5 includes a plurality of grooves 54 formed on the cylinder 2, each slider 52 corresponding to one groove 54, and each groove 54 is divided into a first segment 540 and a second segment 541; it also includes a turntable 55 and a third rod 56 slidably disposed in a certain radial direction of the turntable 55, and an elastic element is provided between the third rod 56 and the turntable 55 in the sliding direction; during the rotation stroke of the turntable 55 driving the third rod 56, when the third rod 56 pushes the slider 52 to move in the first segment 540, the first rod 40 changes from an arc shape to a straight shape, and when the third rod 56 pushes the slider 52 to move in the second segment 541, the first rod 40 changes from a straight shape to an arc shape.

[0040] Specifically, after the sieve plate 4 flips the raw meat (the sieve plate 4 is away from the bottom of the cylinder 2), the slider 52 stops at the end of the first section 540 near the annular groove 53. When the sieve plate 4 presses the raw meat and after the raw meat flips (the sieve plate 4 is near the bottom of the cylinder 2), the slider 52 stops at the end of the second section 541 near the annular groove 53. A notch 57 is opened at each end of the third rod 56, the size of which matches the slider 52. During the rotation of the turntable 55 driven by the replacement source, the third rod 56 is rotated by the turntable 55. When the third rod 56 is not aligned with... Before contact, slider 52 is positioned on the rotation path of the notch 57 at one end of the third rod 56. That is, slider 52 should be aligned with the end of the first segment 540 closest to the annular groove 53 (at this time, the first rod 40 is far from the bottom of the cylinder 2 and is in an arc shape). After the notch 57 at one end of the third rod 56 abuts against slider 52, the third rod 56 continues to rotate, pushing slider 52 out of the annular groove 53 and into the first segment 540. Since slider 52 can only move along the trajectory of the first segment 540, the third rod 56 will be subjected to the force of slider 52 on the turntable 55. If the slider 52 moves radially, it will always be pushed by the third rod 56 during the movement of the first segment 540 until it reaches the junction of the first segment 540 and the second segment 541 (at which point the first rod 40 is in a straight line). Then, the turntable 55 will be driven to reverse direction by the drive source. After the notch 57 at one end of the third rod 56 disengages from the slider 52, the third rod 56 returns to its initial position under the action of the elastic element. At this point, the slider 52 is located on the rotation path of the notch 57 at the other end of the third rod 56. Therefore, the third rod 56 is driven to rotate in the opposite direction, causing its other end... The notch 57 abuts against the slider 52, pushing the slider 52 to slide within the second section 541. Similarly, since the slider 52 can only move along the trajectory of the second section 541, the slider 52 exerts a force on the third rod 56, causing the third rod 56 to move radially on the turntable 55. Therefore, when the slider 52 moves in the second section 541, it will always be pushed by the third rod 56 until the slider 52 is pushed back to the annular groove 53 (at this time, the first rod 40 is close to the bottom of the cylinder 2 and is in an arc shape). In this way, the shape change of the first rod 40 is achieved, and the raw meat is turned over and coated with flour.

[0041] Furthermore, multiple protrusions 42 are arranged on the first rod 40 along its trajectory direction. The overall thickness of the first rod 40 and the protrusions 42 is less than the thickness of the second rod 51. A space 58 is provided inside the columnar block 50. During the stroke when the first rod 40 is driven by the second rod 51 to contact the columnar block 50, the multiple protrusions 42 are successively moved by the columnar block 50 to generate vibration.

[0042] Specifically, during the process of the first rod 40 changing from an arc shape to a straight shape, the end of the first rod 40 needs to follow the second rod 51 through the columnar block 50 for a certain length. The protrusions 42 on the curved first rod 40 are more easily obstructed by the columnar block 50. In order for the first rod 40 to pass through the columnar block 50, the protrusions 42 avoid being squeezed by the columnar block 50. The columnar block has a space 58 inside, which is equivalent to removing the squeezing effect on the squeezed protrusions 42. Therefore, the squeezing of each protrusion 42 by the columnar block 50 is equivalent to a prying action, which can make the first rod 40 vibrate. This vibration can shake the raw meat. After the raw meat is flipped, the powder on the side away from the bottom of the cylinder 2 can be better attached to the raw meat by the shaking action, while the floating powder on the other side can be shaken off to avoid affecting the subsequent powdering, thereby improving the powdering effect of the raw meat.

[0043] Preferably, the first segment 540 gradually becomes shallower in the axial direction along the direction away from the annular groove 53, and the axial depth of the end of the first segment 540 near the annular groove 53 is shallower than the depth of the annular groove 53. The second segment 541 gradually becomes shallower in the axial direction along the direction near the annular groove 53. The depth of the end of the first segment 540 away from the annular groove 53 is deeper than the depth of the end of the second segment 541 away from the annular groove 53.

[0044] Specifically, in the aforementioned embodiment, after the third rod 56 pushes the slider 52 to the junction of the first segment 540 and the second segment 541, it needs to be reversed so that the notch 57 at the other end abuts against the slider 52. At this time, the first rod 40 is in a straight line. During this process, the sieve plate 4 is subjected to the gravity of the raw meat, and the sieve plate 4 tends to bend downwards. When the sieve plate 4 bends downwards, the end of the second rod 51 away from the first rod 40 will tilt upwards, which will cause the notch 57 at the other end of the third rod 56 to not align with the slider 52. Also, when the sieve plate 4 is in an arc shape away from the bottom of the cylinder 2, the slider 52 is aligned with the end of the first segment 540 near the annular groove 53. Similarly, the sieve plate 4 will also tend to deform into a straight line under the gravity of the raw meat, and the slider 52 will also be affected by the weight of the raw meat entering the first segment 540. The problem caused the notch 57 at one end of the third rod 56 to be unable to align with the slider 52. Therefore, in this embodiment, the slider 52 is configured to be elastically expandable and contractable along the axial direction. That is, when subjected to external force, the slider 52 shortens and the internal spring is compressed to generate elastic force. After the external force is removed, it can extend under the action of the spring's rebound force. A wedge surface can be set at the junction of the first segment 540 and the annular groove 53, and at the junction of the first segment 540 and the second segment 541. The wedge surface generates resistance to the movement of the slider 52. When the third rod 56 drives the slider 52 to move, the slider 52 can shorten under the squeezing action of the wedge surface. Thus, the slider 52 can smoothly enter the first segment 540 or the second segment 541, thereby avoiding the above-mentioned problem (the wedge surface is not shown in the figure).
