Description

Technical Field

[0001] This utility model relates to the field of meat processing technology, specifically to a bidirectional pressing device for a slicer. Background Technology

[0002] In the field of meat processing, fully automatic slicers are key equipment for batch slicing, and the performance of their pressing devices directly affects the slicing quality and efficiency. Traditional slicers often use a unidirectional pressing method, such as pressing meat products through a single pressing plate or a unidirectional conveyor belt. This type of structure has the following technical defects: (1) Insufficient pressing stability: Unidirectional pressing is difficult to completely restrict the displacement of meat products during the cutting process. Especially for meats with irregular shapes or soft textures, slippage and displacement are likely to occur, resulting in uneven slice thickness, edge damage, and affecting the finished product qualification rate. (2) Limited adaptability: Traditional pressing devices usually lack an adjustable tensioning structure. When the conveyor belt or pressing belt becomes loose after long-term use, it is difficult to adjust the tension in a convenient way, which can easily cause slippage, reduce the reliability of equipment operation, and increase maintenance costs. Low cleaning efficiency: Meat scraps generated during the pressing process are easy to adhere to the surface of the pressing belt. Existing structures often do not have automatic cleaning components. If they are not cleaned in time, they will not only affect the friction between the pressing belt and the meat products, but may also breed bacteria, which does not meet the hygiene standards of food processing. (3) Poor synchronization: The pressing and conveying systems of some slicers operate independently, and the speed matching between the pressing belt and the conveyor belt is low, resulting in uneven force on meat products during the conveying process, which further affects the slicing accuracy.

[0003] While some improvements have been made in existing technologies to address the aforementioned issues, such as adding unidirectional pressing rollers or simple limiting structures, a systematic bidirectional pressing solution has yet to be established, failing to simultaneously meet multiple requirements including stability, self-cleaning, and tension adjustment. Therefore, there is an urgent need for a high-efficiency pressing device capable of achieving bidirectional synchronous pressing, automatic cleaning, and tension adjustment to improve the automation level and processing quality of meat slicing. Utility Model Content

[0004] The purpose of this invention is to provide a bidirectional pressing device for a slicer to solve the problem mentioned in the background art of not being able to cut and process meat products in large quantities and quickly. This device prevents displacement of meat products during slicing through a bidirectional pressing design, thereby improving slicing stability and efficiency. It is suitable for high-efficiency processing scenarios of fully automatic meat product slicers.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bidirectional pressing device for a slicer, comprising:

[0006] The frame and the conveyor belt fixed to the outer surface of the frame;

[0007] The limiting nylon plates provided on both sides of the outer surface of the conveyor belt are used to limit the conveying path of meat products;

[0008] A worm gear driven by a first servo motor, and a first worm gear and a second worm gear meshing with the worm gear;

[0009] The first rotating frame and the second rotating frame are respectively rotatably mounted on the outer surfaces of the first turbine rod and the second turbine rod.

[0010] The first and second rotating frames are respectively provided with pressing conveyor belts on their outer surfaces. The pressing conveyor belts are connected to the corresponding turbine rods to form a pressing structure that operates synchronously from top to bottom. The counterweights fixedly installed on the outer surfaces of the first and second rotating frames are used to provide downward pressure on the meat products by the pressing conveyor belts.

[0011] To further optimize this utility model, the following technical solutions may be preferred:

[0012] Preferably, elastic brush plate assemblies are slidably mounted on the outer surfaces of the first and second rotating frames. The elastic brush plate assemblies are in contact with the outer surface of the pressing conveyor belt and are used to remove meat scraps and residues from the pressing conveyor belt.

[0013] Preferably, a tensioning self-rolling shaft and a tensioning screw that cooperate with the tensioning self-rolling shaft are slidably installed on the outer surfaces of the first rotating frame and the second rotating frame, respectively, so that the tension of the pressing conveyor belt can be adjusted by adjusting the tensioning screw.

[0014] Preferably, a tensioning screw is provided at one end of the conveyor belt, and the tensioning screw is threadedly connected to the conveyor belt roller to adjust the tension of the conveyor belt.

[0015] Preferably, the pressing conveyor belt and the conveyor belt form a synchronous movement structure in opposite directions, and the linear speed of the pressing conveyor belt matches the linear speed of the conveyor belt to ensure stable clamping and conveying of meat products.

[0016] Preferably, a variable-pitch channel is formed between the pressing conveyor belts of the first rotating frame and the second rotating frame, and the distance between the inlet end of the channel is greater than the distance between the outlet end, forming a gradually narrowing pressing structure.

[0017] Preferably, the surface of the pressing conveyor belt is provided with an anti-slip texture or a flexible coating to enhance the friction against the meat products.

[0018] Preferably, the elastic brush assembly includes an elastic substrate and a detachable brush strip, the brush strip being made of a food-grade flexible material.

[0019] Preferably, the first servo motor is connected to a worm gear via a reducer to form an adjustable drive system, which can be used to adapt to the pressing requirements of different types of meat products.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. High-efficiency and stable pressing: A first servo motor drives a worm gear, which in turn drives the first and second worm gears to rotate synchronously. This creates a pressing structure where the pressing conveyor belts on the first and second rotating frames operate synchronously from top to bottom. Combined with the synchronous movement of the pressing conveyor belt and the matching linear speed of the two belts, this ensures stable clamping and conveying of meat products, preventing them from shifting or slipping during slicing and guaranteeing slicing accuracy and quality. Simultaneously, counterweights on the outer surfaces of the first and second rotating frames provide downward pressure to the pressing conveyor belts, further enhancing the pressing effect. Furthermore, the gradually contracting pressing structure formed between the two pressing conveyor belts gradually compacts the meat products during transport, adapting to the pressing needs of different meat product shapes and improving pressing efficiency.

[0022] 2. Convenient Cleaning and Maintenance: The elastic brush plate assemblies, slidably mounted on the outer surfaces of the first and second rotating frames, fit snugly against the outer surface of the pressing conveyor belt. This allows for timely removal of meat scraps and residues from the conveyor belt, preventing residue accumulation from affecting normal equipment operation and meat product hygiene. The elastic brush plate assemblies feature a detachable design, and the brush strips are made of food-grade flexible material, facilitating replacement and cleaning, reducing maintenance costs, and ensuring food processing safety.

[0023] 3. Flexible Adjustment Function: By setting the tensioning roller and tensioning screw, the tension of the pressing conveyor belt can be adjusted to ensure that the pressing conveyor belt always maintains the appropriate tension and avoids affecting the pressing effect due to loosening. The tensioning screw at one end of the conveyor belt is threadedly connected to the conveyor belt roller, which can realize the adjustment of the conveyor belt tension and ensure the stable operation of the conveyor belt. In addition, the first servo motor is connected to the worm gear through the reducer to form an adjustable drive system, which can flexibly adjust the operating speed and pressure of the pressing conveyor belt according to the characteristics of different types of meat products, expanding the applicability of the device.

[0024] 4. Enhanced clamping effect: The anti-slip texture or flexible coating on the surface of the conveyor belt can effectively enhance the friction of the meat products, prevent the meat products from slipping during the conveying process, further improve the clamping stability, and ensure the smooth operation of slicing.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-9This utility model provides a technical solution: a bidirectional pressing device for a slicer, comprising a frame 1, a conveyor belt 2 fixedly mounted on the outer surface of the frame 1, a first servo motor 5 fixedly mounted on one side of the outer surface of the conveyor belt 2, a second servo motor 16 fixedly mounted on one side of the outer surface of the frame 1, limiting nylon plates 3 fixedly mounted on both sides of the outer surface of the conveyor belt 2, a worm gear 6 rotatably mounted on one end of the outer surface of the conveyor belt 2 and connected to the first servo motor 5, and a first turbine rod 7 and a second turbine rod 8 rotatably mounted on the outer surface of the conveyor belt 2 respectively, and the second turbine rod 8 and the first turbine rod 7 are respectively connected to the worm gear 6. The first turbine rod 7 is rotatably mounted with a first rotating frame 9 on its outer surface, and the second turbine rod 8 is rotatably mounted with a second rotating frame 10 on its outer surface. The outer surfaces of the second rotating frame 10 and the first rotating frame 9 are respectively rotatably mounted with a pressing conveyor belt 12, and the pressing conveyor belt 12 is respectively connected to the first turbine rod 7 and the second turbine rod 8. The outer surfaces of the first rotating frame 9 and the second rotating frame 10 are slidably mounted with an elastic brush plate assembly 15, and the outer surface of the elastic brush plate assembly 15 is in contact with the outer surface of the pressing conveyor belt 12. The outer surfaces of the first rotating frame 9 and the second rotating frame 10 are respectively fixedly mounted with a counterweight 11.

[0037] Firstly, when slicing meat products, simply place the meat products one by one onto the outer surface of conveyor belt 2. The meat products will then move along the direction of conveyor belt 2, and the movement direction of the meat products will be restricted by the limiting nylon plate 3. At the same time, the first servo motor 5 will start, driving the worm gear 6 to rotate. This will allow the first turbine rod 7 and the second turbine rod 8, which mesh with the worm gear 6, to rotate synchronously. With the use of the counterweight 11, after the meat products enter below the first rotating frame 9 and the second rotating frame 10, the pressing conveyor belt 12 can... The synchronous rotation of the conveyor belt 12 ensures that the meat products are firmly pressed down and propelled forward as they pass through. Combined with the movement of the conveyor belt 2, the meat products do not shift randomly when cut by the toothed blades 23. Simultaneously, the elastic brush assembly 15 cleans the surface of the conveyor belt 12, preventing meat scraps from adhering to its surface, reducing slippage caused by debris, improving the stability of the meat products during slicing, and enabling rapid, batch slicing of meat products. This significantly improves the slicing quality, efficiency, and practicality of the slicer.

[0038] A tensioning screw 4 is rotatably mounted on the outer surface of one end of the conveyor belt 2, and the tensioning screw 4 is threadedly connected to the roller at one end of the conveyor belt 2. The roller of the conveyor belt 2 can rotate on its own. Tensioning self-rolling shafts 13 are slidably mounted on the outer surfaces of the first rotating frame 9 and the second rotating frame 10, and the tensioning self-rolling shafts 13 are respectively engaged with the first rotating frame 9 and the second rotating frame 10. Tensioning screws 14 are threadedly mounted on the outer surfaces of the first rotating frame 9 and the second rotating frame 10, and the outer surface of the tensioning screws 14 is in contact with the outer surface of the tensioning self-rolling shafts 13.

[0039] Furthermore, after prolonged use, the meat slicer can move the rollers of the conveyor belt 2 by rotating the tension screw 4, thus tensioning the conveyor belt 2. At the same time, tightening the tension screw 14 can push the tension self-rolling shaft 13 to move, allowing the tension self-rolling shaft 13 to tension the pressing conveyor belt 12. This prevents slippage between the conveyor belt 2 and the pressing conveyor belt 12 during operation, greatly improving the service life and practicality of the slicing device.

[0040] A rotating plug rod 18 is rotatably mounted on the outer surface of the conveyor belt 2, and a connecting rod 17 is rotatably mounted on the outer surface of the rotating plug rod 18. The other end of the connecting rod 17 is rotatably connected to the output end of the second servo motor 16. Sliding rods 19 are slidably mounted inside the conveyor belt 2, with both ends of the sliding rods 19 penetrating the outer surface of the conveyor belt 2 and engaging with the sliding rods 19. A spherical bearing 20 is fixedly mounted on the outer surface of one end of the sliding rod 19. A plug-in sliding rod 21 is rotatably mounted on the outer surface of the rotating plug rod 18, and the outer surface of the plug-in sliding rod 21 is in contact with the outer surface of the rotating plug rod 18. The rod 18 is fixed to the sliding rod 21 with screws. The sliding rod 21 is slidably connected to the spherical bearing 20. The end of the sliding rod 19 that protrudes from the outer surface of the conveyor belt 2 is fixedly installed with a mounting block 22. The outer surface of the mounting block 22 is provided with grooves, and the grooves of the mounting block 22 are arc-shaped. Toothed blades 23 are inserted between the mounting blocks 22, and the toothed blades 23 are engaged with the mounting blocks 22 with screws. The end of the sliding rod 19 away from the second servo motor 16 is fixedly installed with a cleaning brush 24, and the outer surface of the cleaning brush 24 is in contact with the outer surface of the conveying part of the conveyor belt 2.

[0041] Secondly, when the meat products move along the conveyor belt 2 and enter below the first rotating frame 9 and the second rotating frame 10, the second servo motor 16 will rotate simultaneously and drive the connecting rod 17 to rotate. The rotation of the connecting rod 17 drives the rotating insertion rod 18 to swing synchronously, so that the insertion sliding rod 21 can swing synchronously. The swing of the insertion sliding rod 21 drives the joint bearing 20 to rotate and slide, so that the sliding rod 19 connected to the joint bearing 20 can reciprocate in different directions, so that the mounting clamp 22 installed on the outer surface of the sliding rod 19 and the joint bearing 20 can reciprocate. The toothed blade 23 can reciprocate synchronously, allowing it to cut meat products in both directions. This improves the cutting efficiency of meat products while ensuring the stability of the cutting process. As the sliding rod 19 reciprocates, it also drives the cleaning brush 24 to reciprocate, allowing the cleaning brush 24 to clean the outer surface of the conveyor belt 2. After the meat products are cut, they will be removed from under the second rotating frame 10 and sent out of the frame 1 via the conveyor belt 2 to enter the next process, further improving the cutting quality and cleanliness of the slicing device.

[0042] Working principle: During operation, meat products are first placed onto the surface of conveyor belt 2, allowing them to move along the direction of the limiting nylon plate 3. Simultaneously, the first servo motor 5 starts and drives the worm gear 6 to rotate, causing the first turbine rod 7 and the second turbine rod 8, which mesh with the worm gear 6, to rotate synchronously. After the meat products enter below the first rotating frame 9 and the second rotating frame 10, the pressing conveyor belt 12, through the synchronous rotation of the first turbine rod 7 and the second turbine rod 8, combined with the use of the counterweight 11, ensures that the meat products are firmly pressed against the outer surface of conveyor belt 2. Subsequently, the rotation of the second servo motor 16 causes the sliding... The lever 19 can slide synchronously in the opposite direction, allowing the mounting clamp 22 and toothed blade 23 to move back and forth, so as to cut the passing meat products quickly and stably, ensuring the quality of the sliced ​​meat products. At the same time, while the pressing conveyor belt 12 rotates, the elastic brush plate assembly 15 will brush the pressing conveyor belt 12, and the cleaning brush 24 will move back and forth with the sliding lever 19 and brush the outer surface of the conveyor belt 2, ensuring the cleanliness of the pressing conveyor belt 12 and the surface of the conveyor belt 2. Then, the sliced ​​meat products are transported through the conveyor belt 2, so that the cut meat products can be sent out from the frame 1, improving the efficiency and quality of meat product slicing and processing.
