Description

Technical Field

[0001] This utility model relates to the field of food processing technology, and in particular to an automatic cutting device for sandwich grains. Background Technology

[0002] Filled pet food is a special type of pet food, typically consisting of an outer layer and an inner core. The outer and inner layers differ in ingredients, texture, and flavor, resulting in a unique eating experience. With the rapid development of the pet market, pet owners' demands for pet food are becoming increasingly diverse and personalized. As a result, various filled pet food products of different shapes, sizes, and thicknesses have emerged to meet the needs of pets of different breeds, ages, and sizes.

[0003] The production process of stuffed pet food has its unique characteristics: the material is expanded by a screw extruder and then shaped by a cutter. Because the extruder head needs to be designed with a process channel for injecting the stuffing, this technical limitation restricts the extruder head diameter from being too small. Under current process conditions, the size of the material after expansion and cutting is typically around 16×10mm, a specification that basically meets the designed capacity of the equipment. However, the market demand for smaller sizes is growing, such as 8×10mm, 10×10mm, and 13×10mm. These products, suitable for small pets or those with special feeding needs, hold an important position in the market.

[0004] The main difficulty faced by existing technologies is that, in order to reduce the size of sandwiched food to the aforementioned small specifications, the traditional process can only achieve this by reducing the feed rate of the equipment. This directly leads to a sharp drop in production capacity, usually by 30%-50%, which seriously affects production efficiency and economic benefits. Another method is to replace the extruder die of the production equipment, but this process not only requires a 2-3 hour shutdown, but also cannot fundamentally solve the problem of efficient production of small-sized products, because the process structure of injecting the sandwich inside the extruder limits the further reduction in the size of the extruder.

[0005] Therefore, developing an automatic cutting device that can efficiently cut sandwich grains of different specifications and adapt to various specification requirements is of great practical value and technical significance for solving the technical bottlenecks faced by the industry and meeting diverse market demands. Summary of the Invention

[0006] The purpose of this invention is to provide an automatic cutting device for sandwich grains, which can efficiently cut sandwich grains and produce small-sized products without reducing the amount of feed.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: It includes a support frame, a base plate, two vertical plates, and a slitting assembly. The base plate is installed on the upper end of the support frame, and the two vertical plates are fixedly spaced on the upper end of the base plate. The slitting assembly is installed between the two vertical plates. The slitting assembly includes a slitting roller and a smooth roller. The slitting roller is rotatably installed on the upper part between the two vertical plates, and a slitting ring is fixed in the middle of the slitting roller. The smooth roller is rotatably installed on the lower part between the two vertical plates. A conveying channel for transporting sandwich grains is formed between the slitting roller and the smooth roller. A driving mechanism for driving the slitting roller and the smooth roller to rotate simultaneously is provided on one side of one of the vertical plates. An adjustment mechanism for adjusting the pitch angle of the base plate is provided between the support frame and the base plate.

[0008] Preferably, the driving mechanism includes two gears and a drive motor. The two gears are respectively fixed on one side of the slitting roller and the smoothing roller, and the two gears mesh with each other. A protective cover is fixed on one side of one of the vertical plates. The drive motor is fixed on one side of the protective cover, and the output end of the drive motor passes through the protective cover and is coaxially fixed with the slitting roller, so as to drive the slitting roller and the smoothing roller to rotate simultaneously.

[0009] Preferably, the adjustment mechanism includes an adjustment screw, which is rotatably mounted on the front end of the base plate. The lower end of the adjustment screw passes through the support frame, and two limiting nuts are threaded on the outer wall of the adjustment screw. The two limiting nuts are located at the upper and lower parts of the opening of the support frame, respectively, and the diameter of the two limiting nuts is larger than the opening on the support frame, which is suitable for limiting the position of the adjustment screw.

[0010] Preferably, the front ends of the two vertical plates are provided with two guide plates, the side of the two guide plates that are close to each other is provided with a concave arc surface, and the front ends of the two vertical plates are provided with an adjustment mechanism for adjusting the distance between the two guide plates.

[0011] Preferably, the adjustment mechanism includes an adjustment frame fixed to the front end of the two vertical plates, a clamping plate fixed to the lower end of each of the two guide plates, a bidirectional lead screw rotatably mounted inside the adjustment frame, and the lower ends of the two clamping plates respectively threaded onto the outer walls of the two ends of the bidirectional lead screw and slidably connected to the adjustment frame for adjusting the distance between the two guide plates.

[0012] Preferably, one side of the bidirectional lead screw passes through the adjustment frame and is fixed with a handle for driving the bidirectional lead screw to rotate and adjust the distance between the two guide plates.

[0013] Preferably, the upper end of the adjustment frame is fixed with an arc-shaped cover, which is suitable for preventing the residue of the sandwiched grain from falling into the adjustment frame.

[0014] Preferably, one end of each of the two vertical plates is fixed with a guide roller for guiding the slit sandwich grain, and multiple connecting rods are fixed between the two vertical plates for connecting the two vertical plates.

[0015] Preferably, the lower end of the support frame is fixed with a plurality of first support legs, a reinforcing plate is fixed to one side of the support frame, and a second support leg is fixed to one side of the reinforcing plate.

[0016] Compared with the prior art, the advantages of this utility model are as follows: by fixing a slitting ring in the middle of the slitting roller, the sandwich grain can be cut in half, increasing the slitting specifications. It can increase output without frequently changing production equipment or reducing the feeding amount. By setting a drive mechanism, it can drive the slitting roller and the smooth roller to rotate simultaneously to slitting and convey the sandwich grain. By setting an adjustment mechanism, it can adjust the pitch angle of the bottom plate, thereby changing the angle of the slitting component. When the angle of the slitting component is different, the discharge height is also different. This design can effectively prevent the occurrence of material sticking and breakage, and improve the slitting quality. Attached Figure Description

[0024] The present invention will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] like Figure 1-6 As shown, an automatic slitting device for sandwich grains includes a support frame 1, a base plate 2, two vertical plates 3, and a slitting assembly. One side of the base plate 2 is rotatably mounted on the upper end of the support frame 1, allowing the base plate 2 to rotate relative to the support frame 1, facilitating subsequent adjustment of the angle of the slitting assembly. The two vertical plates 3 are bolted to the upper end of the base plate 2, providing a stable mounting base for the slitting assembly.

[0026] The slitting assembly is installed between two vertical plates 3. The slitting assembly includes a slitting roller 4 and a guide plate 9. The slitting roller 4 is rotatably installed at the upper end between the two vertical plates 3. The rotation of the slitting roller 4 can roll and cut the sandwich grain. Due to the arc-shaped groove designed on the slitting roller 4, it can cut indentations into the sandwich grain without cutting it off, which facilitates the conveying after slitting. The rotation of the slitting roller 4 can drive the slitting ring 15 to rotate. The slitting ring 15 is aligned with the middle of the sandwich grain and cuts indentations into the middle part of the sandwich grain. After the material is expanded and shaped by the cutter, the size is about 16*10mm, which basically meets the equipment's capacity. If the size is to be made into smaller sizes such as 8*10mm, 10*10mm, and 13*10mm, according to the traditional device, the only way is to reduce the feeding amount, which leads to a sharp drop in capacity. By adding a cutting ring 15, the 16*10mm particles are cut in half again, which can both increase the output and make the particles smaller. The guide plate 9 is set at the front end of the two vertical plates 3, which plays a guiding role for the sandwich grain and ensures the stability of the sandwich grain position during the cutting process.

[0027] A protective cover 7 is bolted to one side of the vertical plate 3. The protective cover 7 serves two purposes: firstly, it protects the internal transmission components such as the gears 6, preventing accidental injury to operators; secondly, it prevents external dust and other impurities from entering and affecting the normal operation of the transmission components. A drive motor 8 is fixed to one side of the protective cover 7. The output end of the drive motor 8 passes through the protective cover 7 and is fixedly installed to the slitting roller 4 via a coupling. The drive motor 8 provides power for the rotation of the slitting roller 4. By controlling the speed and direction of the drive motor 8, the cutting speed and frequency of the slitting ring 15 can be precisely controlled to meet different slitting process requirements.

[0028] When the drive motor 8 drives the slitting roller 4 to rotate, the gear 6 at one end of the slitting roller 4 drives the gear 6 at one end of the smooth roller 5 to rotate, thereby making the smooth roller 5 rotate synchronously. The rotation of the smooth roller 5 assists in conveying the sandwiched grain on the one hand, and cooperates with the slitting roller 4 on the other hand to make the slitting process more stable and smooth.

[0029] The adjustment mechanism includes an adjustment frame 10 fixed to the front end of two vertical plates 3, and clamping plates 11 fixed to the lower ends of two guide plates 9. A bidirectional lead screw 12 is rotatably mounted inside the adjustment frame 10. The lower ends of the two clamping plates 11 are threaded onto the outer walls of both ends of the bidirectional lead screw 12 and slidably connected to the adjustment frame 10. When the bidirectional lead screw 12 is rotated, since the threads at both ends of the bidirectional lead screw 12 rotate in opposite directions, the clamping plates 11 will slide along the adjustment frame 10 under the action of the bidirectional lead screw 12, thereby adjusting the distance between the two guide plates 9 to meet the cutting requirements of different specifications of sandwiched grains.

[0030] One end of the bidirectional lead screw 12 passes through the adjustment frame 10 and is fixed with a handle 13. By turning the handle 13, the operator can easily drive the bidirectional lead screw 12 to rotate, thereby adjusting the distance between the two guide plates 9. The operation is convenient and quick. The two guide plates 9 have an arc surface at their closest ends. The arc surface design can better guide the sandwiched grain into the cutting area and avoid damage to the sandwiched grain when entering the cutting area.

[0031] An arc-shaped cover 14 is fixed to the upper end of the adjusting frame 10. During the process of cutting sandwich grains, some residues are inevitably generated. The arc-shaped cover 14 can prevent the residues of sandwich grains from falling into the adjusting frame 10, avoid the residues from affecting the normal operation of the bidirectional lead screw 12 and the clamping plate 11, and ensure the service life and adjustment accuracy of the adjusting components.

[0032] The adjustment mechanism includes an adjusting screw 16 rotatably mounted on the front end of the base plate 2. The adjusting screw 16 supports the slitting assembly and adjusts its angle. Two limiting nuts 17 are threaded onto the outer wall of the adjusting screw 16. The lower end of the adjusting screw 16 passes through the support frame 1, and the two limiting nuts 17 are located at the upper and lower ends of the support frame 1, respectively. By adjusting the positions of the two limiting nuts 17 on the adjusting screw 16, the support length of the adjusting screw 16 can be changed, thereby changing the angle of the slitting assembly. When the angle of the slitting assembly is different, the discharge height is also different. This design effectively prevents material sticking and breakage, improving the slitting quality.

[0033] Guide rollers 18 are fixed to one end of each of the two vertical plates 3. The slit sandwich grains are guided by the guide rollers 18 and can be smoothly output from the slitting device, preventing the slit sandwich grains from shifting or falling during the output process, thus ensuring the continuity and stability of the production process. Multiple connecting rods 22 are fixed between the two vertical plates 3. The connecting rods 22 enhance the connection strength between the two vertical plates 3, making the entire slitting device more stable, able to withstand greater external forces during the slitting process, reducing vibration and deformation, and improving slitting accuracy.

[0034] Multiple first support legs 19 are fixed to the lower end of the support frame 1. The first support legs 19 support the entire slitting device, keeping the device in a stable working state. A reinforcing plate 20 is fixed to one side of the support frame 1, and a second support leg 21 is fixed to one side of the reinforcing plate 20. The reinforcing plate 20 and the second support leg 21 further enhance the stability of the support frame 1. Especially when the slitting device vibrates or is subjected to external forces during operation, it can effectively prevent the support frame 1 from tilting or shaking, ensuring the safe operation of the slitting device.

[0035] In actual use, if it is necessary to adjust the angle of the slitting component, it can be achieved by adjusting the position of the two limit nuts 17 on the adjusting screw 16. According to the specifications of the sandwich grain, the bidirectional screw 12 is adjusted by turning the handle 13 so that the distance between the two guide plates 9 is adapted to the width of the sandwich grain. Then, the sandwich grain to be slitted is placed on the smooth roller 5, and the drive motor 8 is started. The drive motor 8 drives the slitting roller 4 to rotate. The slitting roller 4 drives the smooth roller 5 to rotate synchronously through the gear 6. The sandwich grain moves under the action of the relative rotation of the smooth roller 5 and the slitting roller 4. The arc groove designed on the slitting roller 4 can cut the sandwich grain with an indentation without cutting it off, which is convenient for conveying after slitting. The slitting ring 15 cuts the middle part of the sandwich grain. The slitting sandwich grain is smoothly output under the guidance of the guide roller 18.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model.
