Description

Technical Field

[0001] The present invention relates to the technical field of pulverizing devices, and more particularly to a pulverizing device used for food processing. Background Art

[0002] Food raw material crushing device is widely used in food processing industry. Food raw material crushing device is a device used to process food raw materials into powder or finely crushed state. It can cut and grind food raw materials into powder; it is suitable for harder raw materials, such as nuts, condiments, etc.

[0003] A patent application with publication number CN118304988A discloses a food raw material crushing device for food processing and a method of use, including an equipment housing, a feed hopper is fixedly connected to the top of the equipment housing, a support plate is fixedly connected to the top of the feed hopper, a drive motor is fixedly connected to the end of the support plate away from the equipment housing, an output end of the drive motor is fixedly connected to the output shaft, an end of the output shaft away from the drive motor is transmission-connected to a drive belt, an end of the support plate away from the equipment housing is rotatably connected to a crushing shaft, an end of the transmission belt away from the output shaft is transmission-connected to the crushing shaft, a crushing barrel is fixedly connected to the inside of the equipment housing, a plurality of support legs are fixedly connected to the bottom of the crushing barrel, and also includes: a blade cleaning mechanism, the blade cleaning mechanism includes a plurality of rotating blocks fixedly connected to the end of the crushing shaft away from the transmission belt, a plurality of crushing blades are fixedly connected to the side wall of the telescopic rotating block, a plurality of fixed rods are fixedly connected to the top of the equipment housing, a plurality of sliding sheets are slidably connected to the fixed rod, a connecting rod 1 is fixedly connected to the sliding sheet, and a plurality of give-way grooves are provided on the side wall of the crushing barrel. Although this type of crushing device can make food raw materials crush more thoroughly by setting up several rotating blocks, when the crushing blade rotates, the crushing blade will pass through the groove on the scraper block. This setting can scrape off the food raw materials sticking to the surface of the crushing blade, avoid the food raw materials sticking to the surface of the crushing blade, and thus improve the crushing efficiency of the food raw materials.

[0004] However, in the prior art, food raw materials are usually transported from the feed box to the crushing box by gravity or simple mechanical feeding. However, this method is prone to cause the raw materials to accumulate or clog in the feed box when processing raw materials with high humidity or strong viscosity, resulting in unsmooth feeding. The interruption of feeding will directly affect the continuous supply of materials in the crushing box, which will in turn cause the crushing roller to be unable to work continuously and efficiently, affecting the crushing effect. Since the raw materials cannot enter the crushing roller evenly, the crushing process may be uneven, resulting in unstable quality of the finished product.

[0014] Preferably, the baffle is slidably connected to the crushing box.

[0015] Preferably, a thread is provided inside the top block, and the thread is meshed with the screw rod.

[0016] The beneficial effects of the present invention are:

[0017] The pulverizing device for food processing described in the present invention, when actually used, the food raw materials enter into the feed box through the feed hopper, and then fall into the pulverizing box, and then the motor drives the active pulley A to rotate clockwise, and the active pulley A can then drive the driven pulley A to rotate through the transmission belt, and the driven pulley A can then drive the connecting shaft to rotate clockwise, and the connecting shaft can then drive the pulverizing roller to rotate, and the pulverizing roller can then crush the food raw materials, and finally the raw materials fall out from the discharge hopper. At the same time, in this process, the connecting shaft can synchronously drive the active pulley B to rotate, and then drive the driven pulley B to rotate through the transmission belt, and the driven pulley B can then drive the middle shaft to rotate, and the middle shaft can then drive the gear B to rotate through the gear A, and the gear A and the gear B can respectively drive the two sets of middle shafts and blades to rotate, and at this time, when the blades rotate, they can drive the food raw materials to move downward, playing a role. The feeding effect can prevent food raw materials from being blocked in the feed box, thereby improving the feeding efficiency. The present invention drives the rotation of the middle shaft and the blades by designing a transmission system of an active pulley B and a driven pulley B, so that the blades can effectively push the food raw materials downward when rotating, preventing the raw materials from accumulating or clogging in the feed box, ensuring that the food raw materials can continuously and smoothly enter the crushing box, thereby improving the overall feeding efficiency. The rotating feeding function of the blades can effectively prevent the raw materials from accumulating in the feed box, thereby reducing the occurrence of blockage and improving the continuous working ability and reliability of the equipment. At the same time, since the crushing roller rotates and crushes the raw materials under the drive of the connecting shaft, the feeding blades in the feeding process ensure the uniform feeding of the raw materials, which enables the raw materials to enter the crushing roller more evenly, ensuring the continuity and uniformity of the crushing process, thereby improving the crushing effect and having high practicality.

[0018] The present invention discloses a pulverizing device for food processing, wherein the connecting shaft can synchronously drive the driving pulley C to rotate when the connecting shaft rotates, and the driving pulley C can then drive the driven pulley C to rotate through the belt, and the driven pulley C can then drive the short rod to rotate clockwise, and the short rod then drives the extrusion rod to rotate clockwise, and each rotation of the extrusion rod can squeeze the top plate downward, and the top plate drives the bottom frame and the scraper to move downward through the vertical rod, and during the downward movement of the scraper, the inner wall of the discharge hopper can be scraped, and the inner wall of the discharge hopper can be cleaned at this time, and due to the elastic force of the spring, when the extrusion rod is away from the top plate, due to the elastic force of the spring, the spring can drive the top plate to move upward, and the top plate then drives the vertical rod, the bottom frame and the scraper to reset upward in turn, and reciprocates in turn, that is, when the pulverizing roller rotates, the scraper can reciprocate up and down to scrape the inner wall of the discharge hopper, thereby cleaning the inner wall of the discharge hopper. In the invention, while the crushing roller rotates, the scraper can automatically reciprocate up and down to continuously clean the inner wall of the discharge hopper. Compared with the prior art, this automatic cleaning function reduces the need for manual intervention, keeps the discharge hopper clean, prevents the accumulation of residual materials, and thus reduces the risk of blockage. Moreover, since the scraper automatically cleans the inner wall of the discharge hopper during the operation of the equipment, there is no need to stop the equipment for cleaning, thereby reducing the downtime caused by cleaning and improving the continuous working capacity and overall production efficiency of the equipment. Through the continuous cleaning of the scraper, the accumulation of materials on the inner wall of the discharge hopper is avoided, thereby maintaining the unobstructed discharge port and ensuring that the materials can be discharged smoothly. By keeping the discharge hopper clean, corrosion or cumulative wear caused by residual materials is reduced, thereby extending the service life of the discharge hopper and related components, and can more effectively protect the equipment and reduce the frequency of replacement of parts.

[0019] The present invention provides a pulverizing device for food processing. When the pulverizing box is blocked, the staff can turn the screw to rotate. When the screw rotates, it can drive the top block to move, and the top block can then drive the baffle to slide in the pulverizing box. When the pulverizing box moves outward, the gap between the pulverizing roller and the inner wall of the pulverizing box can be enlarged, thereby facilitating material discharge. In this way, the blockage can be cleared in time when it is blocked or stuck. When the pulverizing box is blocked, the present invention can quickly drive the top block and the baffle to slide by turning the screw to adjust the gap between the pulverizing roller and the inner wall of the pulverizing box. Compared with the prior art, this design allows the operator to quickly expand the gap in the event of blockage or jamming, so that the blocked material can be discharged quickly, which greatly reduces the troubleshooting time and improves the overall working efficiency of the equipment. At the same time, because the design can discharge materials in time when blockage occurs, long-term shutdown caused by blockage is avoided, thereby reducing equipment downtime and improving production continuity and stability.

DETAILED DESCRIPTION

[0029] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the present specification. Various examples may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0030] Embodiment 1

[0031] like Figures 1 to 8As shown, a pulverizing device for food processing described in an embodiment of the present invention includes a support frame 1, and a receiving tray 16 is arranged on the inner side of the support frame 1, and the receiving tray 16 is made of austenitic stainless steel. Austenitic stainless steel has extremely strong corrosion resistance and mechanical strength due to its unique crystal structure, and is suitable for use in food processing, ensuring that the surface in contact with food will not be corroded or worn, thereby extending the service life of the equipment. A pulverizing box 2 and a motor 3 are fixedly installed on the surface of the support frame 1. The pulverizing box 2 and the motor 3 are fixed to the support frame 1 by high-strength bolts or welding processes. Bolt connection has the characteristics of convenient disassembly and assembly, and is suitable for parts that require regular maintenance or replacement, while welding connection provides extremely high strength and stability, and is suitable for parts that need to be fixed for a long time. A driving pulley A4 is installed at the output end of the motor 3, and the driving pulley A4 is fixed to the output shaft of the motor 3 by a key connection. This connection method can ensure that the output torque of the motor 3 is stably transmitted to the pulley, and prevent the pulley from slipping or shifting when rotating at high speed.

[0032] A connecting shaft 5 is provided throughout the interior of the crushing box 2, and the connecting shaft 5 can be made of stainless steel or high-strength alloy steel. Stainless steel is corrosion-resistant and suitable for direct contact with food, while high-strength alloy steel has excellent wear resistance and high strength, and can remain stable for a long time under high-load working conditions. A crushing roller 7 is fixedly installed at one end of the connecting shaft 5, and the crushing roller 7 is fixed on the connecting shaft 5 by a key connection or an interference fit. The key connection can effectively prevent the crushing roller 7 from loosening or displacement when rotating at high speed, while the interference fit uses the tightening force of material deformation to ensure the close fit between the crushing roller 7 and the connecting shaft 5, avoiding any form of looseness, and further improving the durability and reliability of the equipment. A driven pulley A6 is fixedly installed at the other end of the connecting shaft 5, and the driven pulley A6 is connected to the driving pulley A4 through a transmission belt. The transmission belt can be made of oil-resistant rubber or polyurethane, which has good wear resistance and oil resistance, ensuring that it will not fail due to wear or chemical corrosion during long-term operation. In this way, the power of the motor 3 can be efficiently and stably transmitted to the crushing roller 7, driving the crushing roller 7 to rotate at high speed, thereby crushing the food raw materials. The top surface of the crushing box 2 is connected to the feed box 8, and the feed box 8 is fixed to the crushing box 2 by flange connection or welding. The flange connection provides good sealing and stability, and is suitable for parts that require frequent disassembly and assembly, while welding is suitable for parts that do not require frequent disassembly, providing higher connection strength and reliability. The top surface of the feed box 8 is connected to the feed hopper 9, and the feed hopper 9 is fixed to the feed box 8 by threaded connection or flange connection. This can ensure that the feed hopper 9 will not loosen or leak during use, thereby ensuring a continuous and stable supply of raw materials.

[0033] A driving pulley B10 is fixedly installed at one end of the driving pulley A4, and the driving pulley B10 is installed on the connecting shaft 5 by a key connection, so that it can be ensured to rotate synchronously when the connecting shaft 5 rotates, and there will be no dislocation or delay. The inner wall of the feed box 8 is rotatably connected to two central shafts 11, and the material of the central shaft 11 can be selected from stainless steel or high-strength alloy steel. Stainless steel has good rust resistance and is suitable for use in food contact parts, while high-strength alloy steel has excellent strength and wear resistance, and can maintain stable performance in long-term use. The central shaft 11 is connected to the inner wall of the feed box 8 through a precision ball bearing. The ball bearing can effectively reduce the friction of the central shaft 11 during rotation, ensure its smooth operation, and extend its service life. A driven pulley B12 and a gear A14 are fixedly installed on the surface of one of the central shafts 11. The driven pulley B12 is fixed to the central shaft 11 by a key connection, and the gear A14 is fixed to the central shaft 11 by a spline or key connection. This connection method can ensure the transmission efficiency and stability between the various components and ensure the smooth transmission of power. A gear B15 is fixedly installed on the surface of the other central shaft 11, and the gear B15 is fixed to the central shaft 11 by a spline or key connection. Blades 13 are fixedly installed on the surfaces of the two central shafts 11, and the blades 13 are fixed to the central shaft 11 by bolt connection or welding, ensuring that they can effectively push the food raw materials downward during rotation, prevent the food raw materials from being blocked in the feed box 8, and improve the feeding efficiency and reliability of the equipment.

[0034] Embodiment 2

[0035] like Figures 3 to 6As shown, in contrast to Example 1, another embodiment of the present invention is as follows: the bottom end of the crushing box 2 is connected to a discharging mechanism, which includes a discharging hopper 17. The discharging hopper 17 can be fixed to the bottom end of the crushing box 2 by welding or flange connection, ensuring that it has good sealing and stability during use and preventing the crushed materials from overflowing. The surface of the discharging hopper 17 is rotatably connected to a short rod 18, which is connected to the surface of the discharging hopper 17 by a high-precision rolling bearing. This connection method can ensure that the short rod 18 maintains a stable motion trajectory during rotation, reduces friction, and improves motion efficiency. A driven pulley C20 is fixedly installed at one end of the short rod 18, and the driven pulley C20 is fixed to the short rod 18 by a key connection or a spline connection, ensuring that it will not loosen during rotation and can stably transmit power to the short rod 18. A driving pulley C19 is fixedly installed on the surface of the connecting shaft 5, and the driving pulley C19 is fixed to the connecting shaft 5 by a key connection, ensuring that it synchronously drives the driven pulley C20 to rotate when the connecting shaft 5 rotates. The surface of the short rod 18 is fixedly installed with an extrusion rod 21, which can be fixed on the short rod 18 by bolt connection or welding, so that it can be ensured that the extrusion rod 21 will not loosen or deviate during the rotation process, and can continuously and effectively contact with the top plate 24 to play a cleaning role. The side of the discharge hopper 17 is fixedly installed with a side block 22, which is fixed on the discharge hopper 17 by welding or bolt connection, ensuring that it has sufficient strength and stability during use. The top surface of the side block 22 is penetrated by a vertical rod 23, and the material of the vertical rod 23 can be selected from stainless steel or high-strength plastic to ensure that it will not bend or break when subjected to external force. The vertical rod 23 is slidably connected to the side block 22, and the vertical rod 23 can be slidably connected by a guide rail or a bearing to achieve smooth sliding, ensuring that when the extrusion rod 21 contacts the top plate 24, the vertical rod 23 can move smoothly without getting stuck or deviating. A top plate 24 is fixedly installed on the top of the vertical rod 23. The material of the top plate 24 can be selected from high-strength plastic or stainless steel to ensure that it will not deform or break when squeezed by the extrusion rod 21, and maintain its structural stability and durability. A base frame 25 is fixedly installed on the bottom end of the vertical rod 23. The base frame 25 is an "L"-shaped structure. A scraper 26 is fixedly installed on one end of the base frame 25. The material of the scraper 26 can be selected from wear-resistant rubber or high-strength plastic. It can clean the inner wall of the discharge hopper 17 without damaging the surface of the discharge hopper 17, and has good wear resistance and flexibility. The surface of the vertical rod 23 is sleeved with a spring 27. The material of the spring 27 is high-elastic spring steel, which has excellent elasticity and fatigue resistance. It can quickly restore its original position when the extrusion rod 21 is away from the top plate 24, ensuring the continuous and efficient operation of the equipment.

[0036] Embodiment 3

[0037] like Figures 7 and 8As shown, in contrast to Example 1, another embodiment of the present invention is as follows: a discharge mechanism is provided on the side of the crushing box 2, and the discharge mechanism includes a baffle 28, which is slidably connected to the side of the crushing box 2 through a sliding groove or a guide rail, and can move smoothly during the adjustment process without getting stuck or offset. A top block 29 is fixedly mounted on the top surface of the baffle 28, and a thread is provided inside the top block 29, which is meshed with a screw rod 30, and the screw rod 30 is connected to the top block 29 through a ball screw or a trapezoidal thread. This design can provide a larger transmission ratio and self-locking ability, ensuring that the top block 29 can move smoothly and accurately during the adjustment process.

[0038] How it works

[0039] The food raw materials enter the feed box 8 through the feed hopper 9, and then fall into the crushing box 2, and then the motor 3 drives the active pulley A4 to rotate clockwise, and the active pulley A4 can then drive the driven pulley A6 to rotate through the transmission belt, and the driven pulley A6 can then drive the connecting shaft 5 to rotate clockwise, and the connecting shaft 5 can then drive the crushing roller 7 to rotate, and the crushing roller 7 can crush the food raw materials at this time, and finally the raw materials fall out from the discharge hopper 17. At the same time, in this process, the connecting shaft 5 can synchronously drive the active pulley B10 to rotate, and then drive the driven pulley B12 to rotate through the transmission belt, and the driven pulley B12 can then drive the middle shaft 11 to rotate, and the middle shaft 11 can then drive the gear B15 to rotate through the gear A14. The wheel A14 and the gear B15 can respectively drive the two sets of central shafts 11 and blades 13 to rotate. At this time, when the blades 13 rotate, they can drive the food raw materials to move downward, which has a feeding effect, avoids the food raw materials from being blocked in the feed box 8, and improves the feeding efficiency. The present invention drives the rotation of the central shaft 11 and the blades 13 by designing a transmission system of an active pulley B10 and a driven pulley B12, so that the blades 13 can effectively push the food raw materials downward when rotating, prevent the raw materials from accumulating or clogging in the feed box 8, ensure that the food raw materials can continuously and smoothly enter the crushing box 2, and improve the overall feeding efficiency. The rotating feeding function of the blades 13 can effectively prevent the raw materials from accumulating in the feed box 8, thereby reducing the clogging phenomenon. The continuous working capacity and reliability of the equipment are improved. At the same time, the crushing roller 7 is driven by the connecting shaft 5 to rotate and crush the raw materials, and the feeding blades 13 in the feeding process ensure the uniform feeding of the raw materials, which enables the raw materials to enter the crushing roller 7 more evenly, ensuring the continuity and uniformity of the crushing process, thereby improving the crushing effect and having high practicality. When the connecting shaft 5 rotates, it can synchronously drive the active pulley C19 to rotate, and the active pulley C19 can then drive the driven pulley C20 to rotate through the belt, and the driven pulley C20 can then drive the short rod 18 to rotate clockwise, and the short rod 18 then drives the extrusion rod 21 to rotate clockwise, and each rotation of the extrusion rod 21 can squeeze the top plate 24 downward, and the top plate 24 passes through the top plate 24. The vertical rod 23 drives the bottom frame 25 and the scraper 26 to move downward. During the downward movement of the scraper 26, the inner wall of the discharge hopper 17 can be scraped, and the inner wall of the discharge hopper 17 can be cleaned at this time. Due to the elastic force of the spring 27, when the extrusion rod 21 is away from the top plate 24, the spring 27 can drive the top plate 24 to move upward due to the elastic force of the spring 27. The top plate 24 then drives the vertical rod 23, the bottom frame 25 and the scraper 26 to reset upward in sequence, and reciprocates in sequence. That is to say, when the crushing roller 7 rotates, the scraper 26 can reciprocate up and down to scrape the inner wall of the discharge hopper 17, thereby cleaning the inner wall of the discharge hopper 17. In the present invention, while the crushing roller 7 rotates, the scraper 26 can automatically reciprocate up and down to continuously clean the inner wall of the discharge hopper 17. Compared with the prior art,This automatic cleaning function reduces the need for manual intervention, keeps the discharge hopper 17 clean, prevents the accumulation of residual materials, and thus reduces the risk of blockage. Moreover, since the scraper 26 automatically cleans the inner wall of the discharge hopper 17 during the operation of the equipment, there is no need to stop the equipment for cleaning, thereby reducing the downtime caused by cleaning and improving the continuous working ability and overall production efficiency of the equipment. The continuous cleaning of the scraper 26 avoids the accumulation of materials on the inner wall of the discharge hopper 17, thereby maintaining the unobstructed discharge port and ensuring that the materials can be discharged smoothly. By keeping the discharge hopper 17 clean, the corrosion or cumulative wear caused by the residual materials is reduced, thereby extending the service life of the discharge hopper 17 and related components, and can more effectively protect the equipment and reduce the frequency of replacing parts. At the same time, when the crushing box 2 is blocked, the staff can turn the screw rod 30 to rotate. When the crushing box 2 is blocked, the top block 29 can be driven to move, and the top block 29 can then drive the baffle 28 to slide in the crushing box 2. When the crushing box 2 moves outward, the gap between the crushing roller 7 and the inner wall of the crushing box 2 can be enlarged, thereby facilitating material discharge. In this way, when the crushing box 2 is blocked, the present invention can quickly drive the top block 29 and the baffle 28 to slide by twisting the screw rod 30, thereby adjusting the gap between the crushing roller 7 and the inner wall of the crushing box 2. Compared with the prior art, this design allows the operator to quickly expand the gap in the case of blockage or jamming, so that the blocked material can be quickly discharged, greatly reducing the troubleshooting time and improving the overall working efficiency of the equipment. At the same time, because the design can discharge materials in time when blockage occurs, long-term shutdown caused by blockage is avoided, thereby reducing equipment downtime and improving production continuity and stability.
