Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to a sand removal device for pre-packaged food raw materials. Background Technology

[0002] A sand removal device for pre-packaged food ingredients is a piece of equipment used to remove impurities such as sand and dirt from pre-packaged food ingredients. A parallel brush roller cleaning device is one type. The parallel brush roller cleaning machine uses the mechanical friction of the brush rollers to peel off the sand particles, combined with the impact of high-pressure water jets to flush away the impurities. The material is conveyed by a mesh belt and washed by multiple sets of brush rollers. Due to its high density, the sand particles settle to the bottom of the water tank and are discharged. It has the following structure:

[0003] 1. Brush roller assembly: The bristles on its surface act directly on the surface of the pre-packaged food raw materials through mechanical friction, peeling off the attached sand, dirt and other impurities;

[0004] 2. Frame: Provides a stable support structure for the entire parallel brush roller cleaning device, fixing the position of various components such as the brush roller assembly and water spray device;

[0005] 3. Water spraying device: sprays high-pressure water jets to impact the raw material after it has been rubbed by the brush rollers, washing away the sand and impurities that have been peeled off from the surface of the raw material.

[0006] Currently, an existing roller peeling and cleaning machine (patent number: CN213763052U) discloses a roller peeling and cleaning machine, including a machine housing, a water spray base, and a feeding box. The machine housing has a rectangular structure with the feeding box connected to one end of its upper surface. The top of the feeding box has a feeding groove. Inside the feeding box, there are two sets of rotating rods. The outer wall of each rotating rod has multiple sets of cylindrical support rods arranged in a ring, with the support rods being equally spaced. The support rods on the two sets of rotating rods interlock with each other. A groove is formed on the side of the feeding box, and the upper surface of the groove has a rectangular water spray base. The bottom surface of the water spray base has a water spray groove. Multiple sets of water spray rods are installed at equal intervals on the inner wall of the water spray groove. Multiple sets of nozzles are connected to the bottom surface of each water spray rod. Multiple sets of movable rods are symmetrically arranged on the outer wall of the water spray base. This roller peeling and cleaning machine effectively prevents raw material blockage and improves cleaning efficiency.

[0007] The feed box is equipped with interlocking support rods to evenly guide the raw materials to be cleaned into the washing machine, preventing the raw materials from entering the machine at the same time and causing blockage. However, during the process of guiding the raw materials, the support rods may collide with the raw materials, which can damage the surface of the raw materials. At the same time, impurities such as sand and mud adhering to the surface of the food are more tightly bound to the surface of the food. Sometimes, it is difficult to completely remove them by relying solely on the brush rollers and water flow. In this case, multiple cleanings are required, which reduces work efficiency. Utility Model Content

[0008] To address the shortcomings of existing technologies, this utility model provides a sand removal device for pre-packaged food raw materials. It solves the technical problem that collisions between the support rod and the raw material during the feeding process can easily damage the surface of the raw material. At the same time, sand, mud, and other impurities adhering to the food surface become more tightly bound to the food surface, making it difficult to completely remove them by relying solely on brush cleaning and water rinsing. This requires multiple cleaning processes, which reduces work efficiency.

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

[0010] A sand removal device for pre-packaged food raw materials includes a frame, an external cleaning mechanism, a mounting frame, and cleaning rollers. The mounting frame is located outside the frame, and there are two sets of cleaning rollers, both sets of which are rotatably connected to the inside of the mounting frame. The external frame is provided with a fixing mechanism for fixing the mounting frame, which includes a positioning groove, threaded holes, and threaded rods. The positioning groove is located outside the frame, and the end of the mounting frame is engaged inside the positioning groove. Two threaded holes are located on the side of the frame corresponding to the positioning groove, and the threaded rods are threaded into the threaded holes and used to restrict the movement of the mounting frame.

[0011] Preferably, a gasket is slidably connected inside the positioning groove, and a guide hole is provided on one side of the frame corresponding to the positioning groove. A guide plate is slidably connected inside the guide hole, and the guide plate is fixedly installed on the outside of the gasket.

[0012] Preferably, the inner side of the mounting frame has two mounting slots, and each mounting slot has a mounting plate that is snapped into it. The two ends of the cleaning roller brush are rotatably connected to the outside of the two mounting plates, and each mounting plate has several adjustment slots on its outside. The end of the cleaning roller brush is rotatably connected to the inside of the adjustment slot.

[0013] Preferably, the mounting frame has a baffle on one side corresponding to each mounting plate to restrict the movement of the mounting plate, and a screw is fixedly installed on one side of the mounting frame corresponding to each baffle. Each screw has a handle threadedly connected to the outside of the screw. The baffle is slidably connected to the outside of the screw. Two limiting grooves are opened on the outside of the mounting frame, and the end of the baffle is engaged in the inside of the limiting groove.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] First, align the left end of the mounting frame with the feed inlet of the machine frame, inserting the end of the mounting frame into the positioning groove. Then, rotate the threaded rods on both sides clockwise to clamp and fix the mounting frame in place by the positioning groove and the gasket. When the raw material enters the mounting frame channel from the feed inlet, its own weight triggers the cleaning roller brush to rotate in opposite directions. Under the friction of the cleaning roller brush, the surface sand particles are initially peeled off. The cleaning roller brush has several flexible bristles fixed on its surface, which avoids damage to the raw material. At the same time, the pre-treated raw material enters the main body of the parallel brush cleaning machine, providing a processing object with a relatively lower impurity content for subsequent cleaning processes. This reduces the fluctuation of the cleaning effect caused by impurity residue, thereby reducing the number of cleaning cycles and improving the overall cleaning efficiency.

[0016] 2. According to the specifications of the raw materials, insert both ends of the cleaning roller brush into the adjustment groove of the mounting plate, then snap the mounting plate into the mounting groove of the mounting frame, and rotate the handle to make the baffle press the mounting plate. At this time, the mounting plate is fixed so as to adapt to raw materials of different sizes and improve the flexibility of the cleaning mechanism. Attached Figure Description

[0024] This application provides a sand removal device for pre-packaged food raw materials, which effectively solves the technical problem that collisions between the support rod and the raw material during the feeding process can easily damage the surface of the raw material. At the same time, the sand, mud and other impurities attached to the food surface are more tightly bound to the food surface, and it is sometimes difficult to completely remove them by relying solely on brush cleaning and water rinsing. In this case, multiple cleanings are required, which reduces work efficiency.

[0025] Example

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the technical solution in this application embodiment effectively solves the technical problem that collisions between the support rod and the raw material during the feeding process can easily damage the surface of the raw material. Furthermore, impurities such as sand and mud adhering to the food surface become more tightly bound to the food surface, making it difficult to completely remove them using only roller cleaning and water rinsing. This necessitates multiple cleaning cycles, thus reducing work efficiency. The overall approach is as follows:

[0027] To address the problems existing in the prior art, this utility model provides a sand removal device for pre-packaged food raw materials, including a frame 1, which is the frame 1 of a parallel brush washing machine. A cleaning mechanism is provided on the outside of the frame 1, including a mounting frame 2 and cleaning roller brushes 3. The mounting frame 2 is located on the outside of the frame 1 at the feed inlet of the frame 1. There are two sets of cleaning roller brushes 3, both sets of which are rotatably connected to the inside of the mounting frame 2. Several flexible bristles are fixed on the surface of the cleaning roller brushes 3. A fixing mechanism for fixing the mounting frame 2 is provided on the outside of the frame 1. The fixing mechanism includes a positioning groove 4, threaded holes 5, and threaded rods 6. The positioning groove 4 is opened on the outside of the frame 1, and the end of the mounting frame 2 is engaged with the inside of the positioning groove 4. There are two threaded holes 5, both of which are opened on the side of the frame 1 corresponding to the positioning groove 4 and communicate with the inside of the positioning groove 4. There are two threaded rods 6, which are threadedly connected to the inside of the threaded holes 5 and used to restrict the movement of the mounting frame 2.

[0028] The mounting frame 2 positions the cleaning roller brush 3, forming a raw material feeding channel. The two sets of cleaning roller brushes 3 rotate in opposite directions, loosening the sand particles on the surface of the material through brush bristle friction. The positioning groove 4 positions the mounting frame 2. After the threaded rod 6 is screwed into the threaded hole 5, it squeezes the gasket 7 and locks the position of the mounting frame 2.

[0029] A gasket 7 is slidably connected inside the positioning groove 4. A guide hole 8 is provided on one side of the frame 1 corresponding to the positioning groove 4. A guide plate 9 is slidably connected inside the guide hole 8. The guide plate 9 is fixedly installed on the outside of the gasket 7. The guide plate 9 cooperates with the guide hole 8 to restrict the sliding direction of the gasket 7 and prevent the gasket 7 from shifting.

[0030] The inner side of the mounting frame 2 has two mounting slots 10, and each mounting slot 10 has a mounting plate 11 snapped into it. The two ends of the cleaning roller brush 3 are respectively rotatably connected to the outside of the two mounting plates 11. The detachable design makes it easy to replace the cleaning roller brush 3.

[0031] Each mounting plate 11 has several adjustment slots 12 on its exterior. The end of the cleaning roller brush 3 is rotatably connected to the inside of the adjustment slot 12 to adjust the distance between the two sets of roller brushes and adapt to different sizes of raw materials.

[0032] Each mounting frame 2 has an L-shaped baffle 13 on one side corresponding to each mounting plate 11 to restrict its movement. A screw 14 is fixedly mounted on one side of each baffle 13 on the mounting frame 2. Each screw 14 has a handle 15 threadedly connected to its exterior. The handle 15 consists of a threaded sleeve and two rectangular plates on either side. The baffle 13 is slidably connected to the exterior of the screw 14. Two limiting grooves 16 are formed on the exterior of the mounting frame 2. The ends of the baffle 13 are engaged inside the limiting grooves 16. After the baffle 13 is inserted into the limiting grooves 16, the handle 15 cooperates with the screw 14 to fix the mounting plate 11.

[0033] Working principle:

[0034] First, align the left end of the mounting frame 2 with the feed inlet of the frame 1, so that the end of the mounting frame 2 is inserted into the positioning groove 4. Then, rotate the threaded rods 6 on both sides clockwise. The front end of the threaded rod 6 pushes the pad 7 to slide horizontally along the guide plate 9 until the pad 7 tightly presses against the end face of the mounting frame 2. At this time, ensure that the mounting frame 2 is clamped and fixed by the positioning groove 4 and the pad 7. According to the raw material specifications, insert both ends of the cleaning roller brush 3 into the adjustment groove 12 of the mounting plate 11. Then, insert the mounting plate 11 into the mounting groove 10 of the mounting frame 2. Then, slide the baffle 13 along the screw 14 to be embedded in the limiting groove 16. Rotate the handle 15 to make the baffle 13 press the mounting plate 11. At this time, the mounting plate 11 is fixed. When the raw material enters the channel of the mounting frame 2 from the feed inlet, its own weight triggers the cleaning roller brush 3 to rotate in opposite directions. Under the action of the friction of the cleaning roller brush 3, the surface sand particles are initially peeled off. The pre-treated raw material then enters the main body of the parallel brush cleaning machine. After subsequent brush washing and water rinsing, deep sand removal is completed.

[0035] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
