Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure-breaking and separation devices, and in particular to an automatic pressure-breaking and separation device for a rice noodle packaging production line. Background Technology
[0002] Rice noodles are a traditional food made from rice and are widely loved by consumers. In the industrial production of rice noodles, the cooked rice noodles are usually cut from long strips into uniform segments to facilitate subsequent weighing, packaging and transportation.
[0003] In existing technologies, traditional rice noodle cutting devices mostly use a cutter to cut long strips of rice noodles in one go. However, because rice noodles have strong elasticity and toughness after cooking, direct cutting with a cutter can easily cause stringing or burrs on the cut edge of the rice noodles. Moreover, the cutter can easily damage or even scratch the surface of the conveyor belt during the cutting process, thereby reducing the operational stability of the equipment and increasing maintenance costs.
[0004] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide an automatic crushing and separating device for a rice noodle packaging production line that provides a clean cut surface and improves the service life of the equipment.
[0006] To achieve this objective, the present invention adopts the following technical solution: an automatic pressing and separating device for a rice noodle packaging production line, comprising a frame, a first conveyor belt, a pre-cutting mechanism, a second conveyor belt, a drive mechanism, a pressing roller, and a discharge chute;
[0007] Both the first conveyor belt and the second conveyor belt are mounted on the frame, with the first conveyor belt positioned above the second conveyor belt and forming an angle between the first conveyor belt and the horizontal plane.
[0008] The pre-cutting mechanism is located on the first conveyor belt and is used to pre-cut the long rice noodles on the first conveyor belt.
[0009] The compression roller is rotatably mounted above the second conveyor belt. The driving mechanism is connected to the compression roller to drive the compression roller to rotate. The compression roller has pressure strips arranged at equal intervals in the circumferential direction. The pressure strips are used to extrude the pre-cut long rice noodles into segments.
[0010] The material discharge chute is located at the end of the second conveyor belt to receive the segmented rice noodles that have been broken and separated.
[0011] Using the above technical solution, in the automatic pressing and separating device of the rice noodle packaging production line, the pre-cutting mechanism includes a rotary motor, an eccentric disc, an annular sleeve, a connecting rod, and a cutter.
[0012] The rotary motor is located at the side end of the first conveyor belt, and the output shaft of the rotary motor is connected to the eccentric disk. The rotary motor is used to drive the eccentric disk to rotate.
[0013] The eccentric disk is provided with an eccentric shaft, which is located inside the annular sleeve. The bottom of the annular sleeve is provided with a connecting rod, the bottom of which is connected to the cutter. The cutter is used to reciprocate in the vertical direction as the eccentric disk rotates.
[0014] Using the above technical solution, in the automatic pressing and separating device of the rice noodle packaging production line, the pre-cutting mechanism further includes a first guide rod and a second guide rod;
[0015] A fixed seat is provided above the eccentric disc. The first guide rod is located on the top of the annular sleeve and is slidably connected to the fixed seat. The second guide rod is located on the side of the first conveyor belt away from the rotating motor and is slidably connected to the cutter.
[0016] Using the above technical solution, in the automatic pressing and separating device of the rice noodle packaging production line, the driving mechanism includes a driving motor and a pulley transmission assembly. The driving motor is located at the side end of the second conveyor belt, and its output shaft is connected to the pressing roller through the pulley transmission assembly.
[0017] In the above-mentioned technical solution, the automatic pressing and separating device of the rice noodle packaging production line further includes a supporting pressure roller in the driving mechanism.
[0018] The three sets of supporting pressure rollers are located at the end of the breaking roller away from the drive motor and are spaced apart along the circumference of the breaking roller. The supporting pressure rollers are used to roll and support the breaking roller.
[0019] Using the above technical solution, in the automatic pressing and separating device of the rice noodle packaging production line, the angle formed between the first conveyor belt and the horizontal plane is 10-30°.
[0020] Using the above technical solution, in the automatic pressing and separating device of the rice noodle packaging production line, the gap between the pressing roller and the surface of the second conveyor belt is 10-20mm.
[0021] Compared with the prior art, the present invention has the following beneficial effects:
[0022] This invention sets a pre-cutting mechanism on the first conveyor belt, creating a weak point for the long rice noodles before they enter the pressing process. The rice noodles then transition to the second conveyor belt under gravity and are pressed at a fixed point by a rotating pressing roller. The pressing roller can use pressure strips to align with the pre-cut seam for segmentation, thereby achieving a structural combination of upper pre-cutting and lower pressing. This separates the shearing and breaking processes, avoiding the stringing and equipment damage caused by direct cutting, and effectively improving the neatness of the break.

[0030] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0031] like Figures 1 to 3 As shown in the figure, this utility model embodiment provides an automatic pressing and separating device for a rice noodle packaging production line, including a frame 1, a first conveyor belt 2, a pre-cutting mechanism 3, a second conveyor belt 4, a drive mechanism 5, a pressing roller 6, and a discharge chute 7. The first conveyor belt 2 and the second conveyor belt 4 are both mounted on the frame 1, with the first conveyor belt 2 located above the second conveyor belt 4, and the first conveyor belt 2 forming an angle α with the horizontal plane. The pre-cutting mechanism 3 is mounted on the first conveyor belt 2 and is used to pre-cut the long rows of rice noodles on the first conveyor belt 2. The pressing roller 6 is rotatably mounted above the second conveyor belt 4. The drive mechanism 5 is connected to the pressing roller 6 to drive the pressing roller 6 to rotate. The pressing roller 6 has pressure strips arranged at equal intervals along its circumference, which are used to compress the pre-cut long rows of rice noodles into segments. The discharge chute 7 is located at the end of the second conveyor belt 4 to receive the segmented rice noodles that have been pressed and separated. The pre-cutting mechanism 3 is installed on the first conveyor belt 2. Before the rice noodles enter the next process, they are partially cut, forming a pre-cut slit of a certain depth, which creates certain weak points in the rice noodles. Then, the rice noodles enter the second conveyor belt 4 located below. The driving mechanism 5 can drive the pressing roller 6 to rotate. The pressing strips arranged equidistantly around the circumference of the pressing roller 6 periodically contact the rice noodles as it rolls, pressing them against the pre-cut slit, so that the rice noodles naturally break into segments along the predetermined position. By adopting this combination of upper pre-cutting and lower pressing process, the shearing and cracking processes can be effectively separated, which reduces damage to the cutting tools and conveyor belts, and avoids problems such as stringing and rough cross-section caused by directly cutting cooked rice noodles, thereby improving the neatness and efficiency of cutting. The pressed rice noodles are transported to the end along the second conveyor belt 4 and collected uniformly through the discharge chute 7, which facilitates the seamless connection of subsequent automated processes such as weighing and packaging.
[0032] like Figure 3As shown, the pre-cutting mechanism 3 further includes a rotary motor 31, an eccentric disk 32, an annular sleeve 33, a connecting rod 34, and a cutter 35. The rotary motor 31 is located at the side end of the first conveyor belt 2, and the output shaft of the rotary motor 31 is connected to the eccentric disk 32. The rotary motor 31 is used to drive the eccentric disk 32 to rotate. An eccentric shaft 321 is provided on the eccentric disk 32. The eccentric shaft 321 is located inside the annular sleeve 33. A connecting rod 34 is provided at the bottom of the annular sleeve 33. The bottom of the connecting rod 34 is connected to the cutter 35. The cutter 35 is used to reciprocate along the vertical direction as the eccentric disk 32 rotates. When the rotary motor 31 starts, it can drive the eccentric disk 32 connected to it to rotate continuously. The eccentric shaft 321 on the eccentric disk 32 rotates in a circular motion within the annular sleeve 33, thereby causing the annular sleeve 33 to float up and down. Then, through the connecting rod 34, it drives the cutter 35 below to achieve reciprocating motion in the vertical direction, thereby making shallow cuts on the rice noodles passing below, forming a continuous and incompletely broken pre-cut seam.
[0033] like Figure 3 As shown, the pre-cutting mechanism 3 further includes a first guide rod 36 and a second guide rod 37. A fixed seat 38 is provided above the eccentric disc 32. The first guide rod 36 is located on the top of the annular sleeve 33 and is slidably connected to the fixed seat 38. The second guide rod 37 is located on the side of the first conveyor belt 2 away from the rotary motor 31 and is slidably connected to the cutter 35. The arrangement of the first guide rod 36 and the second guide rod 37 can improve the stability of the cutter 35 during reciprocating cutting.
[0034] like Figure 1 As shown, the drive mechanism 5 further includes a drive motor 51 and a pulley transmission assembly 52. The drive motor 51 is located at the side end of the second conveyor belt 4, and its output shaft is connected to the breaking roller 6 through the pulley transmission assembly 52. When the drive motor 51 starts, power is transmitted to the breaking roller 6 through the pulley transmission assembly 52, causing the breaking roller 6 to rotate stably around its axis, thereby aligning with the pre-cut seam for breaking operation.
[0035] like Figure 1 As shown, the drive mechanism 5 further includes a support roller 53. Three sets of support rollers 53 are located at the end of the crushing roller 6 away from the drive motor 51 and are spaced apart along the circumference of the crushing roller 6. The support rollers 53 can maintain rolling contact with the outer surface of the crushing roller 6 when it rotates, thereby providing support force to the crushing roller 6 and preventing the crushing roller 6 from swaying or axially shaking due to uneven force.
[0036] like Figure 2As shown, the angle α formed between the first conveyor belt 2 and the horizontal plane is 10-30°. In this embodiment, the angle α formed between the first conveyor belt 2 and the horizontal plane is 20°, so that the rice noodles can slide down onto the second conveyor belt 4 below by gravity.
[0037] Furthermore, the gap between the pressing roller 6 and the surface of the second conveyor belt 4 is 10-20mm. In this embodiment, the gap between the pressing roller 6 and the surface of the second conveyor belt 4 is 14mm. This setting ensures that the pressing strip applies sufficient pressure to the rice noodles during the pressing process, without causing excessive compression, thus avoiding the problem of the rice noodles being flattened, deformed, or having their cross-sections cracked.
[0038] This invention sets the pre-cutting mechanism 3 on the first conveyor belt 2, so that the long rice noodles form a fracture weak point before entering the pressing process. Then, the rice noodles are transferred to the second conveyor belt 4 under the action of gravity, and are pressed at a fixed point by the pressing roller 6 in a rotating state. The pressing roller 6 can use the pressure strip to align with the pre-cut seam to implement segmentation, thereby realizing the structural cooperation of upper pre-cutting and lower pressing, separating the shearing and breaking processes, avoiding the pulling and equipment damage caused by direct cutting, and effectively improving the neatness of the break.
[0039] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
