Description

Technical Field

[0001] This utility model relates to the field of food processing technology, specifically a material crushing device for food materials. Background Technology

[0002] In food processing, it is often necessary to first break down some materials before proceeding with further processing.

[0003] An investigation revealed that a Chinese utility model patent (publication number: CN222152369U) discloses a feeding device for crushing food materials. The device includes a housing with a rotatable filter cylinder inside. A crusher and a receiving hopper are located on the right side of the housing, with the left end of the receiving hopper extending into the filter cylinder. A first screw conveyor and a second screw conveyor are respectively connected to each other on the left side and top of the housing. A first feed hopper is located on the left side of the first screw conveyor, and a second feed hopper connected to the first screw conveyor is located on the left side wall of the housing. A discharge hopper is located on the right side of the housing, below the filter cylinder and extending out of the housing.

[0004] Although the above technical solution can crush food materials and then separate them into different sizes, the size of the crushed food materials may be similar to the diameter of the filter holes. This can easily cause some food materials to get stuck on the surface of the filter holes, which can affect the feeding of food materials over time, leading to blockage and affecting the efficiency of sorting and processing crushed food materials.

[0005] Therefore, this utility model provides a grinding device for crushing food materials to solve the above problems. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This invention provides a grinding device for crushing food materials, aiming to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A feeding device for crushing food materials includes a fixed frame and a feeding mechanism, the feeding mechanism being rotatably mounted on the top inner side of the fixed frame.

[0011] A fixed plate is fixedly installed on one side of the top of the fixed frame. A feed chute is provided on one side of the top of the fixed plate. A drive motor is fixedly installed on one side of the surface of the feed chute. A crushing box is fixedly installed at the bottom of the fixed plate.

[0012] The feeding mechanism includes a mounting plate, on one side of which a second drive motor is fixedly mounted. On one side of the second drive motor is a drive gear fixedly connected. At the bottom of the drive gear is a meshing gear. On the inner wall of the meshing gear is a feeding cylinder fixedly mounted. Filter holes are opened on the outer surface of the feeding cylinder. Baffles are fixedly mounted on both sides of the feeding cylinder. A fixed shaft is fixedly mounted on the surface of the baffle. A ball roller is rotatably sleeved on the surface of the fixed shaft. An extrusion rod is fixedly connected to one side of the ball roller.

[0013] The feeding mechanism is driven by a second drive motor, which in turn drives the meshing gears and the feeding cylinder to ensure stable rotation of the feeding cylinder for thorough crushing of materials. Simultaneously, the filter holes on the outer surface of the feeding cylinder can promptly screen out materials that meet the particle size requirements, improving crushing accuracy and satisfying the fineness requirements of different food processing methods. The combination of the fixed shaft, rollers, and extrusion rods on the baffles on both sides of the feeding cylinder, during the cylinder's rotation, causes the extrusion rods to rotate with the rollers, creating additional pressure on materials stuck on the filter hole surface, preventing food material blockage. Furthermore, the rotating connection between the rollers and the fixed shaft reduces frictional resistance during the extrusion rod's movement, extending the device's lifespan and reducing operating noise, thus providing a more favorable environment for food processing.

[0014] As a preferred technical solution of this application, a discharge plate is fixedly installed at the bottom of the filter hole, a receiving plate is fixedly installed on one side of the surface of the feeding cylinder, and a collection box is fixedly installed on one side of the surface of the receiving plate. The feeding cylinder is installed at an incline on the top of the inner side of the fixed frame. The feeding cylinder is started by a drive motor, which drives the drive gear to rotate. By using the meshing of the gears, the meshing gear rotates, which synchronously drives the feeding cylinder to rotate and adjust. With the help of the inclined structure and the rotation of the feeding cylinder, materials of the correct particle size can fall quickly through the filter hole to the discharge plate to complete the discharge. Larger materials are then transferred to the receiving plate and collected in the collection box, realizing the automatic separation and collection of materials of different particle sizes, reducing manual sorting steps, and improving the continuity and efficiency of material processing.

[0015] As a preferred technical solution of this application, a rotating rod is rotatably installed at the center of the crushing box, and crushing blades are fixedly installed on the surface of the rotating rod. A guide plate is fixedly installed at the bottom of the crushing box, and one side of the surface of the guide plate is connected to the inside of the feeding cylinder. The rotating rod drives the crushing blades to perform preliminary crushing of the material entering the crushing box, reducing the volume of the material in advance and laying the foundation for the subsequent fine processing in the feeding cylinder. The guide plate can guide the material after preliminary crushing into the feeding cylinder, avoid the material from scattering, ensure that all the material participates in the subsequent processing, and improve the material utilization rate.

[0016] As a preferred technical solution of this application, the bottom of the feeding trough is connected to the inside of the crushing box. The rotating rod is driven by a drive motor to rotate, which drives the crushing blades to perform preliminary crushing of the food material fed into the feeding trough. The preliminary crushed food material is then transferred to the inside of the feeding cylinder by a guide plate. The scheme of preliminary crushing of the feeding material by driving the rotating rod and crushing blades by a drive motor realizes the automated connection from feeding to preliminary crushing.

[0017] As a preferred technical solution of this application, the feeding cylinder drives the pre-crushed food material to rotate inside the feeding cylinder through the meshing of the drive gear and the meshing gear. The pre-crushed food material is filtered through the filter holes. The stable power of the gear transmission drives the material to fully tumble inside the feeding cylinder, so that the material is in full contact with the inner wall of the feeding cylinder and other components. Combined with the screening function of the filter holes, it ensures that the material is crushed evenly and meets the particle size requirements, thereby improving the stability of the crushing quality.

[0018] As a preferred technical solution of this application, the filter holes allow smaller, pre-crushed food materials to fall onto the surface of the discharge plate, while larger, pre-crushed food materials are transported to the receiving plate and collected in the collection box as the inclined feeding cylinder rotates. This process can separate qualified materials from materials that require further processing, ensuring the consistency of particle size in the discharged materials and meeting the stringent requirements of food processing for material precision. At the same time, the larger materials collected in the collection box can be further crushed, avoiding material waste and improving resource utilization.

[0019] As a preferred technical solution of this application, the extrusion rod is perpendicular to the filter hole, and the extrusion rod is adjusted by rotating on the surface of the fixed shaft via a roller ball. When the feeding cylinder rotates, the extrusion rod rotates with the roller ball to form targeted extrusion on the material near the filter hole, effectively preventing the material from clogging the filter hole and ensuring smooth filtration. At the same time, the rotation adjustment method reduces the hard friction between the extrusion rod and other components, reduces equipment wear, and extends the service life of the components.

[0020] (III) Beneficial Effects

[0021] The filter holes on the outer surface of the feeding cylinder can promptly screen materials that meet the particle size requirements, improving the crushing accuracy and satisfying the fineness requirements of different food processing methods. Meanwhile, the cleverly designed combination of the fixed shaft, rollers, and extrusion rods on the baffles on both sides of the feeding cylinder, with the extrusion rods perpendicularly aligned with the filter holes, rotates with the rollers as the feeding cylinder rotates, specifically extruding materials stuck on the surface of the filter holes, effectively preventing blockage and ensuring smooth filtration. The rotating connection between the rollers and the fixed shaft reduces the frictional resistance of the extrusion rod movement, lowering equipment wear and extending its service life. It also reduces operating noise, optimizing the food processing environment.

[0022] The discharge plate at the bottom of the filter hole, the receiving plate on one side of the feeding cylinder, and the collection box, together with the inclined and rotatable feeding cylinder, enable materials of the correct particle size to fall quickly onto the discharge plate, while larger materials are transferred to the receiving plate and collected into the collection box, thus achieving automatic separation and collection of materials of different particle sizes and reducing manual sorting.

[0032] 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.

[0033] This utility model provides a feeding device for crushing food materials, such as... Figure 1-6 As shown, it includes a fixed frame 100 and a feeding mechanism 200, which is rotatably mounted on the top inner side of the fixed frame 100.

[0034] A fixing plate 101 is fixedly installed on one side of the top of the fixing frame 100. A feeding trough 102 is provided on one side of the top of the fixing plate 101. A drive motor 103 is fixedly installed on one side of the surface of the feeding trough 102. A crushing box 104 is fixedly installed at the bottom of the fixing plate 101.

[0035] The feeding mechanism 200 includes a mounting plate 203. A second drive motor 204 is fixedly mounted on one side of the surface of the mounting plate 203. A drive gear 205 is fixedly connected to one side of the surface of the second drive motor 204. A meshing gear 202 meshes with the bottom of the drive gear 205. A feeding cylinder 201 is fixedly mounted on the inner wall of the meshing gear 202. A filter hole 206 is opened on the outer surface of the feeding cylinder 201. Baffles 210 are fixedly mounted on both sides of the surface of the feeding cylinder 201. A fixed shaft 211 is fixedly mounted on the surface of the baffles 210. A roller ball 212 is rotatably sleeved on the surface of the fixed shaft 211. An extrusion rod 213 is fixedly connected to one side of the surface of the roller ball 212.

[0036] The feeding mechanism 200 drives the drive gear 205 via the drive motor 204, which in turn drives the meshing gear 202 and the feeding cylinder 201 to rotate, ensuring the stable rotation of the feeding cylinder 201 to fully crush the material. At the same time, the filter holes 206 on the outer surface of the feeding cylinder 201 can promptly screen out materials that meet the particle size requirements, improving the crushing accuracy and meeting the fineness requirements of different food processing. The combination of the fixed shaft 211, roller ball 212 and extrusion rod 213 on the baffles 210 on both sides of the feeding cylinder 201, during the rotation of the feeding cylinder 201, the extrusion rod 213 will rotate with the roller ball 212 to form an additional extrusion effect on the material stuck on the surface of the filter hole 206, avoiding the problem of food material blockage. Moreover, the rotational connection between the roller ball 212 and the fixed shaft 211 can reduce the frictional resistance when the extrusion rod 213 moves, extend the service life of the device, and also reduce operating noise, providing more favorable conditions for the food processing environment.

[0037] like Figure 4As shown, a discharge plate 207 is fixedly installed at the bottom of the filter hole 206, a receiving plate 208 is fixedly installed on one side of the surface of the feeding cylinder 201, and a collection box 209 is fixedly installed on one side of the surface of the receiving plate 208. The feeding cylinder 201 is installed at an incline on the top of the inner side of the fixed frame 100. The feeding cylinder 201 is started by the drive motor 204, which drives the drive gear 205 to rotate. By using the meshing of the gears, the meshing gear 202 rotates, which synchronously drives the feeding cylinder 201 to rotate and adjust. With the help of the inclined structure and the rotation of the feeding cylinder 201, materials of the correct particle size can fall quickly through the filter hole 206 to the discharge plate 207 to complete the discharge. Larger materials are then transferred to the receiving plate 208 and collected in the collection box 209. This realizes the automatic separation and collection of materials of different particle sizes, reduces manual sorting steps, and improves the continuity and efficiency of material processing.

[0038] like Figure 2 As shown, a rotating rod 106 is rotatably installed at the center of the crushing box 104. Crushing blades 107 are fixedly installed on the surface of the rotating rod 106. A guide plate 105 is fixedly installed at the bottom of the crushing box 104, and one side of the surface of the guide plate 105 is correspondingly connected to the inside of the feeding cylinder 201. The rotating rod 106 drives the crushing blades 107 to perform preliminary crushing of the material entering the crushing box 104, reducing the volume of the material in advance and laying the foundation for the subsequent fine processing in the feeding cylinder 201. The guide plate 105 can guide the material after preliminary crushing into the feeding cylinder 201, avoiding material scattering, ensuring that all materials participate in subsequent processing, and improving material utilization.

[0039] like Figure 1-2 As shown, the bottom of the feeding trough 102 is connected to the inside of the crushing box 104. The rotating rod 106 is driven to rotate by the drive motor 103, which drives the crushing blades 107 to perform preliminary crushing of the food material fed into the feeding trough 102. The preliminary crushed food material is then transferred to the discharge cylinder 201 by the guide plate 105. The scheme of using the drive motor 103 to drive the rotating rod 106 and the crushing blades 107 to perform preliminary crushing of the feeding material realizes the automated connection from feeding to preliminary crushing of the material.

[0040] like Figure 2-3 As shown, the feeding cylinder 201 drives the pre-crushed food material to rotate inside the feeding cylinder 201 through the meshing of the drive gear 205 and the meshing gear 202. The pre-crushed food material is filtered through the filter hole 206. The stable power of the gear transmission drives the material to fully tumble inside the feeding cylinder 201, so that the material is in full contact with the inner wall of the feeding cylinder 201 and other components. Combined with the screening effect of the filter hole 206, it ensures that the material is crushed evenly and meets the particle size requirements, thereby improving the stability of the crushing quality.

[0041] like Figure 4-5As shown, the filter hole 206 allows smaller, pre-crushed food materials to fall onto the surface of the discharge plate 207. Larger, pre-crushed food materials are transferred to the receiving plate 208 as the inclined feeding cylinder 201 rotates, and are then collected in the collection box 209. This process can separate qualified materials from those requiring further processing, ensuring the consistency of the particle size of the discharged materials and meeting the strict requirements of food processing for material precision. At the same time, the larger materials collected in the collection box 209 can be further crushed, avoiding material waste and improving resource utilization.

[0042] like Figure 3-6 As shown, the extrusion rod 213 is perpendicular to the filter hole 206, and the extrusion rod 213 is adjusted by rotating on the surface of the fixed shaft 211 via the roller ball 212. When the feeding cylinder 201 rotates, the extrusion rod 213 rotates with the roller ball 212 to form targeted extrusion on the material near the filter hole 206, effectively preventing the material from clogging the filter hole 206 and ensuring smooth filtration. At the same time, the rotation adjustment method reduces the hard friction between the extrusion rod 213 and other components, reduces equipment wear, and extends the service life of the components.

[0043] In summary: First, food materials are fed into the feeding trough 102, whose bottom is connected to the inside of the crushing chamber 104, allowing the materials to enter smoothly. At this time, drive motor 103 starts, driving the rotating rod 106 at the center of the crushing chamber 104 to rotate, which in turn rotates the crushing blades 107 on the surface of the rotating rod 106, thus performing preliminary crushing on the materials entering the crushing chamber 104. The pre-crushed materials, guided by the guide plate 105 at the bottom of the crushing chamber 104, enter the inclined feeding cylinder 201. Then, the feeding mechanism 200 starts working, and drive motor 204 starts, driving the drive gear 205 on its surface to rotate. Because the drive gear 205 meshes with the meshing gear 202, it drives the meshing gear 202 and the feeding cylinder 201 fixed to the inner wall to rotate synchronously. During the rotation of the feeding cylinder 201, the pre-crushed materials inside are agitated and mixed with the feeding material. The material is further crushed by contact with the inner wall of the cylinder 201. At the same time, the fixed shaft 211 and roller ball 212 on the baffles 210 on both sides of the feeding cylinder 201 drive the extrusion rod 213 to rotate. Since the extrusion rod 213 is perpendicular to the filter hole 206 on the outer surface of the feeding cylinder 201, the extrusion rod 213 will form targeted extrusion on the material near the filter hole 206 to prevent the material from clogging the filter hole 206. Subsequently, as the feeding cylinder 201 continues to rotate, smaller materials that meet the particle size requirements fall through the filter hole 206 to the discharge plate 207 at the bottom and are discharged. Larger materials are transferred to the receiving plate 208 on one side of the feeding cylinder 201 as the inclined feeding cylinder 201 rotates, and finally collected in the collection box 209. At the same time, the larger materials collected in the collection box 209 can be crushed again to avoid material waste and improve resource utilization, thereby completing the entire process of crushing, filtering and separating food materials.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
