Description

[0001] The present application relates to the technical field of beef processing equipment, in particular to a fixing device for beef decomposition and segmentation operation. BACKGROUND

[0002] In the beef processing industry, beef decomposition and segmentation is a crucial link, and its efficiency and precision directly affect the quality of beef products and the economic benefits of processing enterprises. With the continuous rise in consumer demand for diversified beef products, operators need to cut standardized pre-made beef modules into corresponding meat block units to meet individual consumer purchasing needs.

[0003] When beef is cut, the beef to be cut is generally placed in a limiting mechanism, and then a cutting mechanism is used to cut the beef in the limiting mechanism. After cutting is completed, meat foam adhesion phenomenon is easy to form on the inner wall of the limiting mechanism. When the residues accumulated on the inner wall of the limiting mechanism cannot be removed in time, it will significantly increase the risk of microbial growth and cross contamination. Currently, the cleaning of the device generally relies on manual intervention cleaning operation, which has a complicated operation process, has cleaning dead angles, and has low overall cleaning efficiency.

[0007] A conveying frame;

[0008] A base is arranged below the conveying frame, the base is rotatably connected with a rotating shaft through a bearing seat arranged on the top of the base, and the outer surface of the rotating shaft is fixedly connected with a limiting seat for placing beef. The limiting seat is slidably connected with a side plate through a slot hole arranged on the top of the limiting seat. The limiting seat is provided with a cleaning member for cleaning meat foam. The base is slidably connected with a cutting machine group through an electric sliding rail arranged on the top of the base. The bottom of the limiting seat is provided with a linkage member for adjusting the position of the side plate.

[0009] The bottom of the base is provided with a driving member for driving the rotating shaft to rotate. When the rotating shaft is turned over by 180 degrees, the cleaning member is started to clean the meat foam adhered to the inner wall of the limiting seat.

[0012] Further, the cleaning element comprises a notch opened in the top of the limiting seat, and the notch is slidably connected with a scraper matched with the inner wall of the limiting seat, the bottom of the scraper is fixedly connected with a guide rod penetrating through the inside of the limiting seat, the guide rod is provided with a plurality of guide rods, the bottom of the plurality of guide rods is fixedly connected with a counterweight frame, and the counterweight frame is connected with the bottom of the limiting seat through the compression spring arranged on the top of the counterweight frame.

[0013] Further, the linkage element comprises a guide groove opened in the bottom of the limiting seat, the guide groove is provided with two groups and is symmetrically distributed along the center of the limiting seat, the guide groove is slidably connected with a moving frame, the bottom of the moving frame is fixedly connected with a counterweight block, and the mass of the counterweight block close to the rotating shaft is greater than that of the counterweight block away from the rotating shaft.

The scraper is tightly attached to the inner wall of the limiting seat, and meat stripping is realized through mechanical scraping.

Furthermore, by using the characteristic that the mass of the counterweight block close to the rotating shaft is greater than that of the counterweight block away from the rotating shaft, when the limiting seat is tilted, the sliding component force of the counterweight block close to the shaft is greater, and the side plate close to the shaft is preferentially attracted by the magnetic member. When the limiting seat is turned to a preset loading angle, the driving torque of the counterweight block close to the shaft overcomes the magnetic force, causing the side plate to reset under the action of the elastic member, preventing the beef from sliding off; the counterweight block away from the shaft resets when the limiting seat resets, driven by the spring force, and the side plate forms a closed cutting cavity, and through the dynamic balance of the counterweight component force, the magnetic force, and the elastic force, the side plate is automatically positioned and reset, ensuring continuous and stable slicing process.

[0035] The base 2 is provided with a discharging plate 21 at the top, and the discharging plate 21 is connected with an external translation mechanism, the discharging plate 21 and the material conveying end of the conveying frame 1 are both designed to be inclined, and the discharging plate 21 and the conveying frame 1 are respectively provided with a roller mechanism.

[0036] The top of the side plate 5 is provided with a butt joint groove matched with the cutter in the cutting machine group 7, and the butt joint groove is provided with a plurality of grooves and is arrayed along the center of the side plate 5, and the side plate 5 is connected with the inner wall of the groove hole through the elastic part arranged outside the side plate 5.

[0037] The cleaning part 6 comprises a slot 61 arranged at the top of the limiting seat 4, and the slot 61 is slidably connected with a scraper 62 matched with the inner wall of the limiting seat 4, the bottom of the scraper 62 is fixedly connected with a guide rod 63 penetrating through the inside of the limiting seat 4, and the guide rod 63 is provided with a plurality of guide rods 63, the bottom of the plurality of guide rods 63 is fixedly connected with a counterweight frame 64, and the counterweight frame 64 is connected with the bottom of the limiting seat 4 through the compression spring arranged at the top of the counterweight frame 64.

[0038] The linkage 8 comprises a guide groove 81 arranged at the bottom of the limiting seat 4, and the guide groove 81 is provided with two groups and is symmetrically distributed along the center of the limiting seat 4, the guide groove 81 is slidably connected with a moving frame 82, the bottom of the moving frame 82 is fixedly connected with a counterweight block 83, and the mass of the counterweight block 83 close to the rotating shaft 3 is greater than that of the counterweight block 83 away from the rotating shaft 3.

[0039] The moving frame 82 is connected with the inner wall of the guide groove 81 through the reset spring 84 arranged outside the moving frame 82, the top of the moving frame 82 is fixedly connected with a magnetic part 85, and the magnetic part 85 and the bottom of the side plate 5 are connected through magnetic force.

[0040] The driving part 9 comprises a driving motor 91 fixedly connected to the bottom of the base 2, the output end of the driving motor 91 is fixedly connected with a driving gear 92, and the end close to the driving motor 91 of the rotating shaft 3 is fixedly connected with a driven gear 93 engaged with the driving gear 92.

[0041] The working principle and advantages of the fixing device for beef decomposition and segmentation operation are as follows:

[0042] The beef feeding process is as follows:

[0043] In actual operation, the operator controls the driving motor 91 in the driving member 9 to make the driving gear 92 rotate coordinately. Based on the meshing transmission mechanism of the driving gear 92 and the driven gear 93, the driven gear 93 drives the rotating shaft 3 to rotate to a preset feeding angle, until the limiting seat 4 and the inclined station of the conveying frame 1 reach a parallel state. In this process, because the limiting seat 4 is in an inclined posture, under the action of the gravity component force of the counterweight block 83 itself, the counterweight block 83 drives the moving frame 82 to displace along the guide groove 81, and makes the reset spring 84 installed on the outer side of the moving frame 82 in a stretched state. With the downward movement of the counterweight block 83, the magnetic member 85 on the moving frame 82 moves synchronously to the position directly below the side plate 5, so that the magnetic member 85 and the side plate 5 are aligned. Under the action of the magnetic adsorption force, the side plate 5 moves quickly along the slot hole until the bottom of the side plate 5 is completely attached to the magnetic member 85, at this time, the side plate 5 and the limiting seat 4 are in the same reference plane, and the beef pieces conveyed by the conveying frame 1 can smoothly enter the limiting seat 4 station.

[0044] It is worth noting that the mass of the counterweight block 83 close to the rotating shaft 3 is greater than that of the counterweight block 83 away from the rotating shaft 3, when the limiting seat 4 is inclined, the sliding component force of the near-axis side counterweight block 83 is greater than that of the far-axis side counterweight block 83. This mechanical property makes the near-axis side counterweight block 83 displace preferentially when the limiting seat 4 is not rotated to the preset feeding angle, and the side plate 5 near the axis is attracted by the magnetic member 85, when the limiting seat 4 is rotated to the preset feeding angle, the driving torque of the near-axis side counterweight block 83 overcomes the adsorption force between the magnetic member 85 and the side plate 5, so that it continues to move along the guide groove 81, causing the magnetic member 85 and the side plate 5 to be misaligned. At this time, the side plate 5 near the axis completes the reset action under the action of the restoring force of the elastic member, thereby effectively preventing the beef pieces from sliding out of the limiting seat 4, and ensuring the continuity and stability of the beef cutting process.

[0045] Beef cutting process:

[0046] When the beef pieces are positioned in the limiting seat 4, the driving member 9 drives the rotating shaft 3 and the limiting seat 4 to perform a reset movement. During the reset stroke, the inclination angle of the limiting seat 4 changes linearly, and the sliding component force of the far-axis side counterweight block 83 gradually decreases. When the component force is less than the elastic force threshold of the reset spring 84, the far-axis side moving frame 82 completes the reset action along the guide groove 81 under the action of the spring restoring force. With the far-axis side moving frame 82 and the side plate 5 misaligned, the far-axis side side plate 5 returns to the initial positioning state under the action of the elastic member. At this time, the two side plates 5 and the inner wall of the limiting seat 4 together form a closed cutting cavity, and the electric sliding rail drives the cutting machine group 7 to be positioned directly above the limiting seat 4. With the vertical feeding movement of the cutting tool, the tool cuts the beef pieces in the closed cavity along the butt joint groove of the side plate 5 to form beef piece units with uniform size precision.

[0047] Beef feeding process:

[0048] When the beef pieces are precisely cut, the electric sliding rail drives the cutting machine group 7 to perform a retreat movement, forming a safe working distance with the limiting seat 4. At this time, the driving part 9 drives the limiting seat 4 to perform angular deflection through the rotating shaft 3 until the preset unloading inclination angle is reached. During the angular adjustment of the limiting seat 4, the near-shaft side counterweight 83 generates a downward component force due to the gravity component, driving the moving frame 82 on the same side to generate directional linear displacement along the guide groove 81. With the translational movement of the moving frame 82, the magnetic part 85 installed thereon synchronously reaches the position directly below the near-shaft side side plate 5, and under the action of the magnetic field attraction force, the side plate 5 generates a vertical downward movement along the slot guide mechanism, realizing the opening state of the near-shaft end of the limiting seat 4.

[0049] At the same time, the external translation mechanism drives the discharge plate 21 to complete the preset trajectory positioning, and its working surface forms a continuous transition surface with the inclined plane of the limiting seat 4. The cut beef pieces slide along the inclined inner wall of the limiting seat 4 (the inner wall of the limiting seat 4 is made of smooth material) under the action of gravity to the discharge plate 21, relying on the roller mechanism inside the discharge plate 21, the beef pieces realize power-free conveying, and finally fall into the collection unit below the base 2. After the unloading process is completed, the driving part 9 cooperates with the rotating shaft 3 to drive the limiting seat 4 to continue rotating until it reaches the preset angle of feeding. At this time, the far-shaft side side plate 5 is automatically opened under the coupling action of the change in the component force of the counterweight 83 and the restoring force of the elastic part, and the beef pieces to be processed in the conveying frame 1 are precisely guided into the limiting seat 4 work station through the guide mechanism, completing the closed-loop connection of the feeding process.

[0050] Limiting seat 4 cleaning process:

[0051] When the accumulated amount of meat attached to the inner wall of the limiting seat 4 exceeds the set threshold, the driving part 9 drives it to perform a 180-degree fixed-axis rotational movement around the central axis through the rotating shaft 3 until it reaches the preset cleaning station. During this movement, the counterweight frame 64 is driven by its own gravity, driving the guide rod 63 and the scraper 62 to generate linear displacement in the vertical direction, and the compression spring is compressed. The edge part of the scraper forms a close-fitting contact pair with the side wall of the limiting seat 4, and through directional linear motion, the meat attached to the inner wall of the limiting seat 4 is scraped, realizing the mechanical stripping of solid impurities.

[0052] It is worth mentioning that the process of rotating the limiting seat 4 to the preset cleaning angle includes two movement stages, a low-speed rotation stage from the initial position to 90 degrees, and a high-speed rotation stage from 90 degrees to 180 degrees. The accelerated rotation in the latter half of the process causes the counterweight frame 64 to generate a transient dynamic load on the compression spring at the bottom of the limiting seat 4, triggering the reciprocating linear motion of the counterweight frame 64 along the axis of the guide rod 63 (the motion is a damped vibration that tends to be stationary when the spring elastic force and the gravity of the counterweight frame 64 reach a balance state). During the vibration process of the counterweight frame 64, the protrusions on the surface of the counterweight frame 64 continuously generate impact load on the bottom of the limiting seat 4, achieving vibration peeling of the meat scraps attached to the bottom. At the same time, the side plates 5 periodically enter and exit the slot hole structure of the limiting seat 4 during the feeding and discharging processes, and the slot hole sidewalls generate a scraping effect on the meat scraps attached to the surface of the side plates 5, ensuring that there is no significant accumulation of meat scraps on the surface of the side plates 5, and only local attachment occurs on the inner wall of the limiting seat 4.

[0053] After completing the cleaning operation, the driving member 9 controls the limiting seat 4 to perform a reverse rotation reset action. During the reset stroke, the elastic recovery force of the compression spring and the gravity of the counterweight frame 64 form a synergistic driving force, prompting the scraper assembly to move in the opposite direction and finally be stored in the slot 61 of the limiting seat 4, completing the standby reset state of the cleaning assembly.

[0054] In the beef block cutting operation, the inner wall of the limiting seat 4 is treated with a smooth surface, and the amount of residual material on the inner wall is relatively low. When the amount of residual material on the inner wall of the limiting seat 4 reaches a preset cleaning trigger threshold, the driving member 9 cooperates with the rotating shaft 3 to perform a cleaning operation of the limiting seat 4, effectively avoiding the problem of reduced cutting efficiency caused by frequent start and stop of the equipment.

[0055] In the present application, the cleaning member 6 and the linkage member 8 have the following advantages:

[0056] Advantage one: the rotating shaft 3 drives the limiting seat 4 to turn 180 degrees by means of the driving member 9. At this time, the counterweight frame 64 is subjected to the action of gravity, driving the guide rod 63 and the scraper plate 62 to move linearly along the inner wall of the limiting seat 4, and the compression spring is compressed. The scraper plate 62 is in close contact with the inner wall of the limiting seat 4, and meat scraps are peeled off by mechanical scraping. During the accelerated rotation of the limiting seat 4 in the latter half of the process, the counterweight frame 64 generates a transient dynamic load on the compression spring, triggering reciprocating linear vibration, and impact load is used to achieve vibration peeling of the meat scraps at the bottom of the limiting seat 4, replacing manual cleaning, improving cleaning efficiency, and reducing the risk of microbial contamination.

[0057] The second advantage is that the linkage counterweight controls the opening and closing of the side plate 5, ensuring the continuity of the cutting. By using the feature that the mass of the counterweight block 83 close to the rotating shaft 3 is greater than that of the counterweight block 83 far from the rotating shaft 3, when the limiting seat 4 is tilted, the sliding force of the near-axis side counterweight block 83 is greater, and the near-axis side plate 5 is preferentially attracted by the magnetic member 85. When the limiting seat 4 is turned to the preset loading angle, the driving torque of the near-axis side counterweight block 83 overcomes the magnetic force, causing the side plate 5 to reset under the action of the elastic member, preventing the beef from sliding off. The far-axis side counterweight block 83 resets when the limiting seat 4 resets, and the side plate 5 is driven to form a closed cutting cavity. Through the dynamic balance of the counterweight force, magnetic force, and elastic force, the automatic positioning and resetting of the side plate 5 are realized, ensuring the continuity and stability of the cutting process.

[0058] The third advantage is that the side plate 5 is connected to the inner wall of the slot through the outer elastic member. During the cutting process, the elastic member can absorb part of the impact force generated during cutting, acting as a buffer and reducing the vibration of the side plate 5 and the limiting seat 4, thereby improving the stability of the cutting process and ensuring the cutting quality.

[0059] The fourth advantage is that the magnetic member 85 at the top of the moving frame 82 in the linkage member 8 is magnetically connected to the bottom of the side plate 5. When the limiting seat 4 is tilted, the moving frame 82 is moved by the counterweight block 83, the magnetic member 85 is quickly aligned and attracted to the side plate 5, causing the side plate 5 to quickly move to the same plane as the limiting seat 4, achieving quick positioning of the side plate 5, shortening the loading preparation time, and improving production efficiency.

[0060] The fifth advantage is that the whole process is automatically connected, improving production efficiency. Through the cooperative work of the driving member 9, electric sliding rail, and translation mechanism, the whole process of automatic control is realized, including beef loading from the conveying frame 1, limiting seat 4 positioning, cutting machine set 7 cutting, discharge plate 21 unloading, and automatic cleaning of the limiting seat 4. This reduces the manual operation steps, shortens the production cycle, and improves the production efficiency of beef decomposition and the economic benefits of processing enterprises.

[0061] The sixth advantage is that the vibration stripping is combined with mechanical scraping, making the cleaning more thorough. The cleaning process is divided into two stages: low-speed rotation scraping and high-speed rotation vibration. During the first half of the low-speed rotation, the scraper 62 removes the side wall meat by mechanical scraping. During the second half of the accelerated rotation, the counterweight frame 64 generates impact load by vibration, stripping the stubborn meat at the bottom, achieving dual cleaning of "scraping + vibration" and covering the entire inner wall of the limiting seat 4.

[0062] The above examples are only used to illustrate the technical solutions of the present application, and are not limited thereto. Although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that modifications can be made to the technical solutions described in the foregoing examples, or some technical features can be replaced by equivalents. Such modifications or replacements do not change the essence of the corresponding technical solutions, and do not deviate from the protection scope of the technical solutions of the embodiments of the present application.
