Abstract
Description
Technical Field
[0001] This utility model belongs to the field of food forming and processing equipment, and in particular relates to a forming device for pellet-shaped food. Background Technology
[0002] Ball-shaped foods are usually formed using a ball-rolling machine. Existing ball-rolling machines, such as... Figure 4 As shown, the device includes an extrusion mechanism with two pelletizing cylinders at the outlet. Material is extruded into a strip shape and passes between the two pelletizing cylinders. The two cylinders rotate in opposite directions, compressing the strip material into granules. The two cylinders also move at a high frequency in the axial direction, causing the granules to move back and forth and be pelletized. However, during use, it was found that because the two cylinders rotate continuously, a standard circle is formed between them to accommodate the granules. This standard circle quickly reopens as the cylinders continue to rotate, resulting in a short formation time. This makes it difficult to pelletize the material into perfectly round shapes; the pellets are often elliptical, leading to lower pelletizing quality. Utility Model Content
[0003] The purpose of this invention is to provide a pellet-forming device for food products. This invention has the advantage of producing high-quality pellets.
[0004] The technical solution of this utility model is as follows: A forming device for pellet-shaped food includes an extrusion mechanism. The discharge end of the extrusion mechanism is equipped with a belt conveyor. A cutting and feeding mechanism is provided on one side of the belt conveyor, and an inclined lower rubbing plate is provided on the other side of the belt conveyor. An upper rubbing plate that reciprocates is slidably connected to the upper side of the lower rubbing plate. Multiple lower rubbing grooves are provided on the top surface of the lower rubbing plate, and multiple upper rubbing grooves corresponding to the positions of the lower rubbing grooves are provided on the bottom surface of the upper rubbing plate. The upper rubbing grooves and the lower rubbing grooves form a channel with a circular cross-section.
[0005] In the aforementioned pellet-shaped food forming device, the cutting and feeding mechanism includes a push plate located on the upper side of the conveying surface of the belt conveyor, a blade plate is provided at one end of the push plate near the extrusion mechanism, and a cylinder is connected to the middle of the push plate.
[0006] In the aforementioned pellet-shaped food forming device, the cutting edge of the blade is inclined toward the belt conveyor.
[0007] In the aforementioned pellet-shaped food forming device, a motor is provided at the bottom of the lower rubbing plate, and a first connecting rod and a second connecting rod are provided between the motor and the upper rubbing plate. One end of the first connecting rod is fixed to the output end of the motor, and the other end of the first connecting rod is hinged to the second connecting rod. The second connecting rod is hinged to the side wall of the upper rubbing plate.
[0008] In the aforementioned pellet-shaped food forming device, the upper part of the bottom surface of the upper rubbing plate is provided with an inclined extrusion surface.
[0009] In the aforementioned pellet-shaped food forming device, slide rails are provided on both sides of the lower rubbing plate, and the slide rails are connected to the upper rubbing plate through a slider.
[0010] In the aforementioned pellet-shaped food forming device, the bottom of the lower rubbing plate is provided with a first support foot of fixed length and a second support foot of adjustable length. Both the first and second support feet are hinged to the lower rubbing plate. The first support foot is close to the belt conveyor, and the second support foot is away from the belt conveyor.
[0011] Compared with existing technologies, this invention uses an extrusion mechanism to compress materials into strips, and a cutting and feeding mechanism to cut the strips and push them onto a lower rubbing plate. Because the lower rubbing plate is inclined, the strips slide down between the two rubbing plates, are cut into granules, and then enter corresponding channels. Under the action of the two relatively moving rubbing plates, they are kneaded into balls. Since the channel cross-section always remains a standard circle, the granules are kneaded for a longer time in this standard circular state, resulting in very round balls with high quality. Therefore, this invention has the advantage of high-quality ball production.
[0012] Furthermore, by setting the cutting edge of the blade to be inclined towards the belt conveyor, the blade applies downward pressure to the strip material when cutting it, increasing the friction between the strip material and the belt conveyor. This prevents the strip material from moving with the guide plate, ensuring a thorough cut. The extrusion surface ensures that the strip material is squeezed and divided into multiple granules on the lower rubbing plate. The inclination angle of the lower rubbing plate is adjustable to ensure smooth discharge. Attached Figure Description

Detailed Implementation
[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the present invention.
[0019] Example: A forming device for pellet-shaped food, such as Figure 1 As shown, it includes an extrusion mechanism 1, such as a screw extruder. The discharge end of the extrusion mechanism 1 is equipped with a belt conveyor 2. The belt conveyor 2 can be grounded by a support frame. One side of the belt conveyor 2 is equipped with a cutting and feeding mechanism, and the other side of the belt conveyor 2 is equipped with an inclined lower rubbing plate 3. The upper side of the lower rubbing plate 3 is slidably connected to a reciprocating upper rubbing plate 4. The upper part of the bottom surface of the upper rubbing plate 4 is equipped with an inclined extrusion surface 13. The top surface of the lower rubbing plate 3 has multiple lower rubbing grooves 5 with semi-circular cross sections. The bottom surface of the upper rubbing plate 4 is equipped with multiple upper rubbing grooves 6 corresponding to the positions of the lower rubbing grooves 5. The upper rubbing grooves and the lower rubbing grooves 5 form a channel with a circular cross section. The distance between adjacent channels should be as small as possible to facilitate the extrusion of strip-shaped materials.
[0020] The cutting and feeding mechanism includes a push plate 7 located on the upper side of the transmission surface of the belt conveyor 2. A blade 8 is provided at one end of the push plate 7 near the extrusion mechanism 1. The cutting edge of the blade 8 is inclined towards the belt conveyor 2. A cylinder 9 is connected to the middle of the push plate 7. The cylinder 9 can be fixed on the frame or support frame of the conveyor 2.
[0021] The bottom of the lower washboard 3 is provided with a motor 10. A first connecting rod 11 and a second connecting rod 12 are provided between the motor 10 and the upper washboard 4. One end of the first connecting rod 11 is fixed to the output end of the motor 10, and the other end of the first connecting rod 11 is hinged to the second connecting rod 12. The second connecting rod 12 is hinged to the side wall of the upper washboard 4.
[0022] Both sides of the lower washboard 3 are provided with slide rails 14, and the slide rails 14 are connected to the upper washboard 4 through sliders 15.
[0023] The bottom of the lower washboard 3 is provided with two fixed-length first support legs 16 and two adjustable-length second support legs 17. Both the first support legs 16 and the second support legs 17 are hinged to the lower washboard 3. The first support legs 16 are closer to the belt conveyor 2, and the second support legs 17 are farther away from the belt conveyor 2. The second support leg 17 includes a square tube with its upper end hinged to the lower washboard 3. A telescopic rod is provided inside the square tube, and a bolt is provided on the square tube to connect the telescopic rod. After the bolt is loosened, the telescopic rod can move axially to change the length of the second support leg 17.
[0024] Working principle: The material is formed into a strip by the extrusion mechanism 1 and falls onto the belt conveyor 2. The feeding speed of the belt conveyor 2 is kept equal to the extrusion speed. When one end of the strip material approaches the discharge end of the belt conveyor 2, the cylinder 9 quickly extends and retracts. The cutter plate 8 first contacts the material to cut it, and then the push plate 7 contacts the material to push the strip material out of the belt conveyor 2 and onto the lower rubbing plate 3. The cylinder 9 can be connected to a compressed air source through a solenoid valve. The solenoid valve is connected to the mains power through a timer (KG316T). The time interval for one opening and closing of the solenoid valve is set on the timer, which is the time interval for one extension and retraction of the cylinder 9, thus setting the cutting length of the strip material.
[0025] Motor 10 drives the upper rubbing plate 4 to move back and forth via the first connecting rod 11 and the second connecting rod 12. Under gravity, the material flows down along the lower rubbing plate 3 and enters the space between the upper and lower rubbing plates 4 and 3 under the action of the extrusion surface 13. There, it is cut into granules and kneaded into balls. Due to the back-and-forth movement of the upper rubbing plate 4, the balls also move back and forth between the upper and lower rubbing plates. However, because the lower rubbing plate 3 is tilted, the downward movement of the balls exceeds the upward movement in each back-and-forth motion, ultimately resulting in discharge from the lower end of the lower rubbing plate 3. By changing the length of the second support leg 17, the tilt of the lower rubbing plate 3 is altered, ensuring smooth discharge of the balls. A container can be placed below the lower end of the lower rubbing plate 3 to catch the falling material.
