Description

Technical Field

[0001] This utility model belongs to the field of dairy processing technology, specifically a dairy processing shearing device. Background Technology

[0002] Dairy product shearing devices specifically refer to mechanical equipment used in dairy product processing to achieve material mixing, dispersion, emulsification, and homogenization by applying high-speed shearing force. Its core function is to break up material particles and form a uniform and stable emulsion or suspension.

[0003] Existing dairy product shearing devices include: a drive system, a shearing mechanism, a temperature control system, and a feeding and discharging system. The drive motor drives the main shaft to rotate, which in turn causes the stator and cutting blade to rotate, thereby shearing the dairy products.

[0004] However, existing shearing devices still have some problems. When shearing dairy products, the spindle is located inside the dairy product. When shearing dairy products with high viscosity, the dairy product is easy to adhere to the spindle, which makes the surface of the spindle prone to the accumulation of microorganisms. Therefore, the device needs to be cleaned, which increases the downtime of the device and reduces the shearing efficiency of dairy products. Therefore, a dairy product shearing device for processing is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and address the problems of existing equipment, this utility model proposes a dairy product shearing device for processing.

[0006] The technical solution adopted by this utility model to solve its technical problem is a dairy product shearing device for processing, including: a hollow shaft servo motor, the output end of which is fixedly connected to a main shaft, a transmission tube inserted inside the hollow shaft servo motor and extending into the interior of the main shaft, an air pump installed at one end of the transmission tube, a rotary joint installed at the output end of the transmission tube, the rotary joint installed inside one end of the main shaft, a PTFE bushing fixedly connected to the outside of the main shaft, the PTFE bushing having threaded grooves, and microporous air channels on both the main shaft and the PTFE bushing. When the threaded grooves rotate, they can push the cheese to flow axially, avoiding local accumulation or stagnation, thereby improving shearing efficiency and uniformity.

[0007] Preferably, the other end of the main shaft is threaded with a blade, one side of the hollow shaft servo motor is threaded with a connecting frame, the lower surface of the connecting frame is fixedly connected with a connecting rod, one end of the connecting rod is threaded with a feed frame, the main shaft passes through the feed frame, the blade is located inside the feed frame, and a mounting bracket is installed on the main shaft. The hollow shaft servo motor is started by an external controller, which drives the main shaft, the cutting blade, the PTFE bushing and the blade to rotate, causing the cheese to flow upward from the bottom of the blade and the connecting frame, and cooperate with the cutting blade to cut the cheese.

[0008] Preferably, a positioning rod is installed on one side of the mounting bracket, an adjustment groove is provided on the outer quarter of the positioning rod, a positioning groove is provided inside the positioning rod, a rotating rod is rotatably connected inside the adjustment groove, one end of the rotating rod extends to the outer side of the positioning rod, and a cutting blade is threaded to one end of the rotating rod. Because five sets of transverse grooves are provided at 90° on the outer side of the adjustment groove, the angle of the cutting blade can be adjusted according to the different viscosities of dairy products.

[0009] Preferably, a spring is fixedly connected to the other end of the rotating rod. The spring is located inside the mounting bracket and the positioning rod. A damping pad is fixedly connected to the outside of the rotating rod. A locking block is installed on the outside of the rotating rod. The locking block is movably connected inside the adjusting groove. The damping pad can increase the friction with the inner wall of the positioning rod, thereby improving the stability of the cutting blade when the position of the cutting blade is fixed.

[0010] Preferably, a plug rod is fixedly connected to one side of the rotating rod, and a rubber pad is fixedly connected to one end of the plug rod. Elastic plates are installed on the rubber pad and the plug rod. The rubber pad and the plug rod are movably connected inside the positioning groove. After the rubber pad enters the positioning groove, the elastic plate pushes the rubber pad back to a flat state, thereby cooperating with the damping pad and the locking block to make the cutting blade more stable during cutting.

[0011] Preferably, the shearing device is externally connected to a controller, which is used to control the start and stop of the hollow shaft servo motor and the air pump. By controlling the hollow shaft servo motor and the air pump through the external controller, the ease of use of the shearing device is improved.

[0012] The advantages of this invention are as follows: by combining the air pump, the transmission pipe and the microporous air channel, an air film is formed on the outer surface of the main shaft, thereby preventing dairy products from sticking to the main shaft surface during shearing. When the threaded groove rotates, it can push the cheese to flow axially. The lubricating properties of the PTFE bushing can prevent the protein, fat and other components in the cheese from sticking to the main shaft at high temperatures, reducing residual contamination and improving product hygiene. Thus, with the combination of the PTFE bushing, the threaded groove and the air film, the risk of microbial growth can be reduced, the frequency of downtime for cleaning can be reduced, and the shearing efficiency of cheese can be improved.

[0013] This invention uses a rotating cutting blade to adjust its cutting angle. The angle of the cutting blade is fixed by the cooperation of the adjusting groove, the locking block, the positioning groove, and the rubber pad. Because there are 5 sets of horizontal grooves at 90° on the outside of the adjusting groove, the angle of the cutting blade can be adjusted according to the different viscosities of dairy products. This allows the shearing device to cut dairy products of different viscosities, thereby expanding the application range of the shearing device. Attached Figure Description

[0021] 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 scope of protection of the present utility model.

[0022] Please see Figure 1-5As shown, a dairy product shearing device for processing includes: a hollow shaft servo motor 1, a main shaft 2 fixedly connected to the output end of the hollow shaft servo motor 1, a transmission pipe 3 inserted inside the hollow shaft servo motor 1 and extending into the interior of the main shaft 2, an air pump 4 installed at one end of the transmission pipe 3, a rotary joint 5 installed at the output end of the transmission pipe 3, the rotary joint 5 installed inside one end of the main shaft 2, a PTFE bushing 6 fixedly connected to the outside of the main shaft 2, a threaded groove 7 on the PTFE bushing 6, microporous air passages 8 on both the main shaft 2 and the PTFE bushing 6, a blade 9 threadedly connected to the other end of the main shaft 2, a connecting frame 10 threadedly connected to one side of the hollow shaft servo motor 1, a connecting rod 11 fixedly connected to the lower surface of the connecting frame 10, a feed frame 12 threadedly connected to one end of the connecting rod 11, the main shaft 2 passing through the feed frame 12, the blade 9 located inside the feed frame 12, and a mounting bracket 13 installed on the main shaft 2;

[0023] In existing dairy processing, high-viscosity products such as cheese and butter often require shearing. Therefore, a dairy shearing device is needed. In actual use, when shearing cheese, the upper and lower support plates of the device are connected by a lifting cylinder. The lifting cylinder moves, pushing the shearing device upwards, increasing the distance between the bottom of the device and the lower support plate. Then, the can containing the dairy product to be sheared is placed at the bottom of the device. The lifting cylinder then retracts, causing the shearing device to descend, so that the cutting blade 18 and the blade 9 are both inside the dairy product to be sheared. Subsequently, the hollow shaft servo motor 1 is activated by an external controller, driving the main shaft 2, cutting blade 18, PTFE bushing 6, and blade 9 to rotate. This causes the cheese to flow upwards from the bottom of the blade 9 and connecting frame 10, working in conjunction with the cutting blade 18 to shear the cheese. During the dairy product shearing process, the air pump 4 is activated by the external controller, allowing gas to pass through the transmission... The gas enters the main shaft 2 through the pipe 3. The gas needs to be purified into sterile compressed air to avoid contamination of the cheese. Then the gas is blown out through the microporous air channel 8, forming an air film on the surface of the PTFE bushing 6 and the threaded groove 7. The air film is formed before the cheese comes into contact with the main shaft 2, preventing adhesion at the source. When the threaded groove 7 rotates, it can push the cheese to flow axially, avoiding local accumulation or stagnation, thereby improving shearing efficiency and uniformity. The PTFE bushing 6 has an extremely low coefficient of friction, which can reduce the frictional energy consumption between the main shaft 2 and the cheese, making the shearing process smoother. In addition, the lubricating properties of the PTFE bushing 6 can prevent the protein, fat and other components in the cheese from sticking to the main shaft 2 at high temperatures, reducing residual contamination and improving product hygiene. Thus, with the cooperation of the PTFE bushing 6, the threaded groove 7 and the air film, the risk of microbial growth can be reduced, the frequency of downtime for cleaning can be reduced, and the shearing efficiency of cheese can be improved.

[0024] Please see Figure 1-5As shown, a positioning rod 14 is installed on one side of the mounting bracket 13. An adjustment groove 15 is opened on the outer quarter of the positioning rod 14. A positioning groove 16 is opened inside the positioning rod 14. A rotating rod 17 is rotatably connected inside the adjustment groove 15. One end of the rotating rod 17 extends to the outer side of the positioning rod 14. A cutting blade 18 is threadedly connected to one end of the rotating rod 17. A spring 19 is fixedly connected to the other end of the rotating rod 17. The spring 19 is located inside the mounting bracket 13 and the positioning rod 14. A damping pad 20 is fixedly connected to the outer side of the rotating rod 17. A locking block 21 is installed on the outer side of the rotating rod 17. The locking block 21 is movably connected inside the adjustment groove 15. An insertion rod 22 is fixedly connected to one side of the rotating rod 17. A rubber pad 23 is fixedly connected to one end of the insertion rod 22. Elastic pieces 24 are installed on the rubber pad 23 and the insertion rod 22. The rubber pad 23 and the insertion rod 22 are movably connected inside the positioning groove 16. An external controller is connected to the shearing device. The external controller is used to control the start and stop of the hollow shaft servo motor 1 and the air pump 4.

[0025] When shearing low-viscosity dairy products, the angle of the cutting blade 18 is between 10° and 20°; when shearing high-viscosity dairy products, the angle of the cutting blade 18 is between 20° and 30°. This improves the efficiency and quality of shearing dairy products. To adjust the angle of the cutting blade 18, press the cutting blade 18 and the rotating rod 17 against the mounting bracket 13, causing the locking block 21 to move out of the horizontal groove of the adjusting groove 15, and driving the rubber pad 23 out of the positioning groove 16. This releases the fixation of the cutting blade 18 angle and simultaneously compresses the spring 19. Then, rotating the cutting blade 18 changes the position of the locking block 21 in the horizontal groove of the adjusting groove 15, thereby adjusting the angle of the cutting blade 18. The part has three sets of positioning grooves 16, and the three sets of positioning grooves 16 are respectively opposite to the horizontal grooves of the adjustment groove 15. After the angle of the cutting blade 18 is adjusted, the pressure on the cutting blade 18 and the rotating rod 17 is released. The spring 19 pushes the locking block 21 into the corresponding horizontal groove of the adjustment groove 15. The insertion rod 22 and the rubber pad 23 are forced into the corresponding positioning groove 16. When the rubber pad 23 enters the positioning groove 16, the elastic piece 24 is compressed. After the rubber pad 23 enters the positioning groove 16, the elastic piece 24 pushes the rubber pad 23 back to a flat state, thus cooperating with the damping pad 20 and the locking block 21 to make the cutting blade 18 more stable when cutting and prevent the cutting blade 18 from rotating on its own.

[0026] Working principle: When shearing low-viscosity dairy products, the angle of the cutting blade 18 is between 10° and 20°; when shearing high-viscosity dairy products, the angle of the cutting blade 18 is between 20° and 30°. Pressing the cutting blade 18 and the rotating rod 17 against the mounting bracket 13 causes the locking block 21 to move out of the horizontal groove of the adjusting groove 15, and also causes the rubber pad 23 to move out of the positioning groove 16, thus releasing the fixation on the angle of the cutting blade 18. Rotating the cutting blade 18 changes the position of the locking block 21 in the horizontal groove of the adjusting groove 15, thereby adjusting the angle of the cutting blade 18. After the angle adjustment is complete, releasing the pressure on the cutting blade 18 and the rotating rod 17 allows the spring 19 to push the locking block 21 into the corresponding horizontal groove of the adjusting groove 15, and the insert rod 22 and the rubber pad 23 are forced into the corresponding positioning groove 16, thus cooperating with the damping pad 20 and the locking block 21, so that when the cutting blade 18 shears... To ensure greater stability and prevent the cutting blade 18 from rotating independently, the hollow shaft servo motor 1 is activated via an external controller, driving the main shaft 2, cutting blade 18, PTFE bushing 6, and blades 9 to rotate. This causes the cheese to flow upwards from the bottom of the blades 9 and connecting frame 10, working in conjunction with the cutting blade 18 to cut the cheese. During the dairy product cutting process, the air pump 4 is activated via the external controller, and gas is blown outwards through the microporous air channel 8, forming an air film on the surface of the PTFE bushing 6 and the threaded groove 7. As the threaded groove 7 rotates, it can push the cheese to flow axially, avoiding local accumulation or stagnation. The PTFE bushing 6 has an extremely low coefficient of friction, thereby reducing the frictional energy consumption between the main shaft 2 and the dairy product. With the cooperation of the PTFE bushing 6, the threaded groove 7, and the air film, the risk of microbial growth can be reduced, the frequency of downtime for cleaning can be reduced, and thus the cutting efficiency of cheese can be improved.
