Description

Technical fields:

[0001] This invention relates to the field of weaving machinery and equipment, and more specifically to a continuous weaving and cutting process for sushi roll curtains and its processing equipment. Background technology:

[0002] Sushi rolls are made by weaving multiple bamboo skewers together with rope. For example, the sushi roll weaving machine described in Chinese patent application number 200810219833.1 consists of a motor, gearbox, cam mechanism, feeding mechanism, sensor, and pull rod mechanism, achieving fully automated production. However, for each sushi roll, a rope needs to be installed at the pull rod plate on the pull rod mechanism before weaving. After completing one roll, another rope needs to be installed, and so on. This constant installation of ropes after each roll increases labor costs and significantly reduces the efficiency of continuous processing, resulting in poor quality.

[0003] Furthermore, after weaving a sushi roll mat, the rope needs to be tied manually, which is labor-intensive, inefficient, and very troublesome. Some methods use glue, but the glued area becomes quite hard after solidification, and it easily melts when the sushi roll mat is heated for sterilization. Moreover, the raw materials used for glue do not meet food-grade requirements and are basically unusable. Summary of the Invention:

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a continuous weaving and cutting process for sushi rolls. It only requires installing a weaving tube with the weaving thread wound on it to achieve continuous weaving. The weaving effect and efficiency are very high. Moreover, the woven sushi rolls can be ultrasonically cut as needed. At the same time as cutting, the joints are welded, eliminating the need for manual knotting and making it very efficient.

[0005] The solution of the present invention to the aforementioned technical problem is:

[0006] A continuous weaving and cutting process for sushi roll mats includes the following steps:

[0007] The first step is to place the bamboo skewers to be processed into the bamboo skewer placement rack of the bamboo skewer feeding and conveying device. The bamboo skewers are continuously conveyed downwards along the channel between the front vertical circular rod and the vertical circular rod. Through the rotation of the ratchet, they are conveyed all the way to the bottom.

[0008] The second step is to insert the two braided material cylinders one after the other into the corresponding horizontal bars of the frame of the braided thread feeding device;

[0009] The third step is to thread the ropes of the two braided tubes of each frame along the corresponding threading positions, and finally clamp the front end of the ropes between the pressure roller and the first rotating guide roller to complete the threading.

[0010] The fourth step involves setting the sushi roll weaving length on the equipment's control unit, turning on the equipment, and having the bamboo skewer feeding and conveying device push the bamboo skewers into all the truncated cone holes of the weaving pushing device, positioning them between the corresponding upper and lower ropes. Then, all the ropes rotate 180° to form a knot. Simultaneously, the pushing block moves forward, pushing the bamboo skewers out of all the truncated cone holes, so that the knot is in front of the bamboo skewers and moves forward together. At the same time, the first rotating guide roller rotates a certain angle, causing the rope or weaving material at the first rotating guide roller to move forward a certain distance. After continuous weaving reaches the set length, all the ropes rotate 180° at least twice to form multiple continuous knots, and then continue continuous weaving.

[0011] Fifth step: After the rope in the whole roll of weaving material is woven to the point that it can no longer be woven, remove the continuously woven sushi roll from the equipment;

[0012] Step 6: Place the removed sushi roll into an ultrasonic cutter and ultrasonically cut it at the point where there are continuous knots.

[0013] The control host sets the weaving length of the sushi roll curtain to determine the number of bamboo skewers to be woven.

[0076] The guide wheel 302 and the guide conveyor wheel 301 are positioned opposite the bottom bamboo stick.

[0077] Furthermore, the threading through hole of the threading sleeve 50 is a tapered through hole with a smaller inner diameter at the left end and a larger inner diameter at the right end.

[0078] A continuous weaving and cutting process for sushi roll mats includes the following steps:

[0079] The first step is to place the bamboo skewers to be processed into the bamboo skewer placement rack 25 of the bamboo skewer feeding and conveying device 20. The bamboo skewers are continuously conveyed downwards along the channel between the front vertical circular rod and the vertical circular rod. Through the rotation of the ratchet, they are conveyed all the way to the bottom.

[0080] The second step is to insert the two braiding cylinders 100 one after the other into the corresponding horizontal bars of the frame of the braiding thread feeding device 10.

[0081] Thirdly, insert the two braided material cylinders 100 onto the corresponding transverse bars of the frame. Then, pass the ropes of the two braided material cylinders 100 out from the side through holes 1 on both sides, then pass them in from the corresponding winding side through holes 2, then extend them out from the center through hole of the main rotating shaft 121, pass through the first through hole 124 of the transverse extension bar 123, and then pass out from the second through hole 125. The two ropes between the first through hole 124 and the second through hole 125 are located on both sides of the limiting post 126 and clamped on the gasket 1. The tension of the rope is achieved between the corresponding wall surfaces of 27 and the transverse extension strip 123; the two ropes coming out of the second through hole 125 pass through the two central through holes of the corresponding central drive shaft 32, and are located on both sides of the guide rod 33. After crossing through the corresponding slot 331, they pass out through the two wire through holes 341 of the corresponding circular plate 34, and are pulled forward along the vertical through slot 451 of the corresponding push block 45. They are then clamped between the pressure roller 318 and the first rotating guide roller 315 to complete the wire threading.

[0082] The fourth step involves setting the sushi roll weaving length on the control unit of the equipment. This length is determined by the number of bamboo skewers, such as setting the sushi roll weaving length to 50 or 60 bamboo skewers. This can be done by simply inputting 50 or 60 into the input screen on the control unit (the control unit is a conventional control component, which will not be described in detail here; in this embodiment, the photoelectric sensor 412 on the equipment is used for sensing and counting). The equipment is then turned on. The bamboo skewer feeding and conveying device pushes the bamboo skewers into all the truncated cone holes of the weaving pushing device, positioning them between the corresponding upper and lower ropes. Then, all the ropes rotate 180° to form a knot. Simultaneously, the pushing block pushes forward, ejecting the bamboo skewers from all the truncated cone holes, so that the knot is in front of the bamboo skewers and moves forward together. At the same time, the first rotating guide roller rotates a certain angle, causing the rope or weaving material at the first rotating guide roller to move forward a certain distance. After continuous weaving reaches the set length, all the ropes rotate 180° at least twice to form multiple continuous knots, and then continue continuous weaving.

[0083] Fifth step: After the rope in the whole roll of woven material is woven to the point that it can no longer be woven, remove the continuously woven sushi roll from the equipment. At the same time, remove the remaining rope that can no longer be marked on the equipment, and install the new woven material roll 100 and bamboo skewers that need to be processed later.

[0084] The sixth step is to place the removed sushi roll mat into the ultrasonic cutting machine 900, with the continuous knotted part positioned between the bottom surface of the cutting blade 907 and the horizontal metal strip 908, and placed on the horizontal metal strip 908. Then, by turning on the ultrasonic cutting machine 900, the push rod of the lifting cylinder 920 is pushed, causing the ultrasonically heated cutting blade 907 to descend, cutting and melting the knotted part on the horizontal metal strip 908. The connection is firm and has relatively low hardness, making it easy to use.

[0085] In this embodiment, during equipment operation, the process is as follows: during operation, the swing drive motor drives the horizontal slider 212 to move left and right.

[0086] Initially, the limiting head 2321 presses against the vertical limiting post 1 on the left side, so that the right end face of the limiting head 2321 presses against the left end face of the corresponding protrusion 2311, and the outer wall of the large diameter end of the conical sleeve 234 presses against the support wheel 245. Through the elastic force of the buffer spring 233, the conical sleeve 234 and the support wheel 245 are kept close and will not loosen. The bottom of the first clamping part 241 is moved backward, the spring 244 is compressed, and the top of the first clamping part 41 and the top of the second clamping part 42 open to form an opening. At this time, the bottom bamboo stick is exactly at the opening.

[0087] Then, by moving the horizontal slider 212, the horizontal slider 212 moves to the right until the right end of the horizontal adjusting rod 232 presses against the vertical limiting post 1 on the right side, causing the horizontal adjusting rod 32 to move to the left, causing the conical sleeve 34 to move to the left, and the buffer spring 33 to compress. At this time, the conical sleeve 34 separates from the guide wheel 45, and the spring 44 returns to its original position. At this time, the bottom of the first clamping part 41 returns to its original position, causing the top of the first clamping part 41 and the top of the second clamping part 42 to come together, clamping the bottommost bamboo stick. Then, as the horizontal slider 212 moves to the left, the clamped bamboo stick moves to the left, and the left end of the bamboo stick is inserted into the through hole formed in the middle of the threading sleeve 250, and extends out from it and enters between the guide guide wheel 302 and the guide conveying wheel 301 (the guide guide wheel 302 is pressed against by the adjusting spring). This allows for height adjustment. When a bamboo skewer is inserted, the guide wheel 302 is lifted, but it remains clamped between the guide wheel 302 and the guide conveyor wheel 301. The conveyor motor rotates the guide conveyor wheel 301, which in turn drives the bamboo skewer to be conveyed quickly to the left. The bamboo skewer is then inserted between all the frustum holes (the diameter of the left end of the frustum hole is smaller than that of the right end, which ensures that the bamboo skewer can be inserted smoothly) and the corresponding upper and lower ropes. Its leftmost end presses against the side baffle 411 to achieve positioning. At this time, the photoelectric sensor 412 senses the bamboo skewer, indicating that it has moved into place, and sends the sensing signal to the control host (the control host is electrically connected to all electrical equipment and components in this embodiment through electrical connection lines to achieve control), indicating that the bamboo skewer is in place and can operate normally.

[0088] During the bamboo skewer feeding process, the drive motor 4 is running, driving the corresponding components. When the bamboo skewer is inserted into the frustum holes of all the threading blocks 42, it rotates the corresponding upper and lower ropes 180°, thus forming a knot. At the same time as the knot is formed, the drive motor 4 also pushes forward through the push block 45, pushing the bamboo skewer out of all the frustum holes (during the push, the upper pressure block 43 is lifted, thus pushing the bamboo skewer out), causing the front of the bamboo skewer at the knot to move forward together. At this time, the drive motor 4 also drives the first rotation guide. Roller 315 rotates at a certain angle, causing the rope or woven material at the first rotating guide roller 315 to move forward a certain distance. In this way, bamboo skewers and rope can be gradually woven and finally output from the first rotating guide roller 315. The control host (a conventional component that can be purchased directly and will not be detailed here) can be programmed to require the upper and lower ropes to rotate two consecutive 180° rotations after 50, 60, or more bamboo skewers have been inserted (depending on the settings). This determines the distance between the next bamboo skewer and the nearest one in front, facilitating subsequent cutting. The conveying beam carrying 50 or 60 bamboo skewers is counted by the number of rotations of a horizontal turntable driven by a oscillating motor. The oscillating motor is a servo motor, which facilitates counting. Alternatively, the photoelectric sensor 412 in this embodiment can be electrically connected to the control host to achieve the counting function. This is a conventional structure and will not be detailed here. The photoelectric sensor 412 in this embodiment can be a diffuse reflection sensor or other types of sensing.

[0089] During the processing, bamboo skewers can be continuously added when there are not enough. Generally, when the photoelectric sensor 412 cannot detect bamboo skewers, it sends a sensing signal to the control host (if no bamboo skewers are detected, the counting stops). The control host then controls the equipment to stop running, so that bamboo skewers can be added manually or the equipment can be checked for jamming.
