Abstract
Description
Technical Field
[0001] This invention relates to food processing technology, and more particularly to a knotting device and knotting process. Background Technology
[0002] In the food processing industry, knotting bean curd sheets is a common process, mainly used to make bean curd sheet knots, bean curd sheet rolls, and other similar foods. Currently, knotting bean curd sheets primarily relies on manual operation, where operators need to wind the bean curd sheets into a loop and then manually tie the knot. This method has the following significant drawbacks: First, manual operation is inefficient and cannot meet the needs of large-scale production in the modern food processing industry.
[0003] Secondly, the quality of knotting is unstable, with inconsistent knot size and tightness, resulting in uneven product quality.
[0004] Manual operation easily leads to broken bean curd skins or loose knots, resulting in waste of raw materials. Furthermore, prolonged repetitive labor can cause operator fatigue, affecting work efficiency and product quality. While some automated equipment exists, it generally suffers from complex structures, poor adaptability, and inconsistent knotting quality, failing to effectively solve the aforementioned technical challenges.
[0005] Therefore, there is an urgent need for a bean curd knotting device that is simple in structure, easy to operate, highly automated, and produces stable knotting quality, in order to meet the food processing industry's demand for efficient and high-quality production. Summary of the Invention

The first drive motor drives the turntable to rotate, the first cylinder is mounted on the turntable, the annular frame is provided at the output end of the first cylinder, and the sleeve is provided at the top end of the annular frame.
[0010] In a knotting device of the present invention, the winding assembly further includes a first control cylinder and a first clamping plate.

The third drive motor is disposed on the back of the guide rail plate, and the eccentric cam is mounted on its output shaft. The slide rail is disposed on one side of the guide rail plate, and the slider is mounted on the slide rail. The guide rail is mounted on the slider. One end of the guide rail is connected to the eccentric cam, and the other end is fixedly mounted with the support frame. The second control cylinder and the second clamping plate are mounted on the support frame. The second control cylinder is used to drive the opening and closing of the second clamping plate.
[0014] In a knotting device of the present invention, the third drive motor drives the eccentric cam to rotate, and the rotational motion of the eccentric cam is converted into the linear reciprocating motion of the guide rail, which drives the support frame to move up and down, so that the second clamping plate can extend into the interior of the sleeve.
[0015] In a knotting device of the present invention, the cutting assembly includes a horizontal rod, a vertical rod, a first connecting plate, a second connecting plate, an adjusting plate, a second adjusting cylinder, a third control cylinder, and scissors.

[0016] In a knotting device of the present invention, the installation angle of the second adjusting cylinder is 30-60 degrees.
[0017] The knotting device and knotting process of this invention have the following beneficial effects:
[0018] This device integrates four functional modules: feeding, winding, knotting, and cutting. Through the coordinated work of motors, cylinders, and mechanical structures, it achieves a fully automated process for knotting bean curd skins, significantly improving production efficiency, reducing labor costs, and meeting the needs of large-scale production.
[0019] By precisely controlling the rotation of the winding component and the clamping process of the knotting component, the size and tightness of each bean curd knot are ensured to be consistent, and the product quality is stable and controllable, effectively solving the quality fluctuation problem caused by manual operation.

Detailed Implementation
[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
[0034] Example 1
[0035] Reference Figures 1 to 11 As shown, this embodiment proposes a knotting device, including a winding assembly 10, a feeding assembly 20, a knotting assembly 30, and a cutting assembly 40.
[0036] Furthermore, the winding assembly 10 includes a first mounting plate 101, on the back side of which a first drive motor 102 is mounted. A turntable 103 is fixedly connected to the output shaft of the first drive motor 102, and a first cylinder 104 is mounted on the turntable 103. An annular frame 105 is provided at the output end of the first cylinder 104. Under the action of the first cylinder 104, the annular frame 105 is driven to move.
[0037] The annular frame 105 has a sleeve 106 at its top, and the sleeve 106 has a conical structure. The sleeve 106 has a slot 107 that runs through its interior and exterior.
[0038] Refer again Figure 3 As shown, the winding assembly 10 also includes a first control cylinder 108 and a first clamping plate 109. The first control cylinder 108 is mounted on the ring frame 105 and is used to control the opening and closing of the first clamping plate 109.
[0039] Furthermore, the feeding assembly 20 includes a base plate 201, on which a ball screw 202 is mounted. The ball screw 202 is connected to a second drive motor 203, which controls the rotation of the ball screw 202. A sliding frame 204 is provided on the ball screw 202, and a first adjusting cylinder 205 is mounted on the sliding frame 204. A discharge head 206 is mounted on the output shaft of the adjusting cylinder 205, and strips of bean curd skin are pulled out along the discharge head 206.
[0040] A roller frame 207 is provided on one side of the discharge head 206. The roller frame 207 is used to straighten the strip-shaped bean curd skin so that it can be fed into the discharge head 206 and pulled out by the discharge head 206.
[0041] In this embodiment, refer again Figure 6 As shown, the feeding assembly 20 is located on one side of the winding assembly 10, and the strip-shaped bean curd skin pulled out by the discharge head 206 is clamped on the first clamping plate 109. Then, the first drive motor 102 drives the turntable 103 and the sleeve 106 on it to rotate, so that the strip-shaped bean curd skin is wound around the sleeve 106 once.
[0042] Furthermore, the tie assembly 30 includes a mounting plate 301, on which an adjusting rod 302 is provided. A guide rail plate 303 is adjustable up and down on the adjusting rod 302. A third drive motor 304 is provided on the back of the guide rail plate 303, and an eccentric cam 307 is mounted on the output shaft of the third drive motor 304.
[0043] The guide rail plate 303 is provided with a slide rail 305 on the side away from the third drive motor 304, and a slider 306 is installed on the slide rail 305.
[0044] The slider 306 is equipped with a movable guide rail 308, wherein the direction of movement of the guide rail 308 is perpendicular to the direction of movement of the slider 306 on the slide rail 305.
[0045] One end of the guide rail 308 is connected to the eccentric cam 307, and a support frame 309 is fixedly installed on the other end. A second control cylinder 311 and a second clamping plate 310 are installed on the support frame 309. The second control cylinder 311 is used to drive the second clamping plate 310 to open and close.
[0046] In this embodiment, the third drive motor 304 drives the eccentric cam 307 to rotate. The rotational motion of the eccentric cam converts the rotational motion into the linear reciprocating motion of the guide rail 308. One end of the guide rail 308 is connected to the eccentric cam 307, and the other end is fixedly mounted on the support frame 309, causing the support frame 309 to reciprocate vertically. A second control cylinder 311 and a second clamping plate 310 are mounted on the support frame 309. The second control cylinder 311 controls the opening and closing of the second clamping plate 310. When the support frame 309 moves up and down to a suitable position, the second clamping plate 310 clamps the wrapped bean curd skin. Under the control of the second control cylinder 311, the second clamping plate 310 tightens the bean curd skin, forming a knot. The height of the guide rail plate 303 can be adjusted by the adjusting rod 302 to accommodate bean curd skin of different lengths.
[0047] Furthermore, the shearing assembly 40 includes a transverse bar 401 and a longitudinal bar 402, which are mounted by a first connecting plate 403 and a second connecting plate 404 that are perpendicular to each other.
[0048] An adjustment plate 405 is provided on the first connecting plate 403.
[0049] A second adjusting cylinder 406 is installed obliquely on the adjusting plate 405 at a certain angle (adjusted according to actual conditions, generally 30-60°). A third control cylinder 407 is provided at the output end of the second adjusting cylinder 406, and a scissor 408 is installed on the outside of the third control cylinder 407. The third control cylinder 407 is used to control the opening and closing of the scissors 408 to cut bean curd sheets.
[0050] In this embodiment, the extension and retraction of the second adjusting cylinder 406 drives the third control cylinder 407 to move on the adjusting plate 405, adjusting the starting position of the scissors 408. The third control cylinder 407 controls the opening and closing of the scissors 408, which is mounted on the outside of the third control cylinder 407.
[0051] Once the bean curd skin is pulled into a knot, the second adjusting cylinder 406 adjusts the scissors 408 to a suitable position. The third control cylinder 407 drives the scissors 408 to close, cutting the bean curd skin. After cutting, the scissors 408 open under the action of the third control cylinder 407 to prepare for the next cut. The cutting angle (30-60°) can be adjusted appropriately according to the material and thickness of the bean curd skin to ensure the cutting effect.
[0052] Furthermore, this embodiment proposes a knotting device with the following working process:
[0053] Feeding stage: The second drive motor 203 in the feeding assembly 20 drives the ball screw 202 to rotate. The ball screw 202 drives the sliding frame 204 to move along the base plate 201, and the first adjusting cylinder 205 on the sliding frame 204 drives the discharge head 206 to pull out the strip-shaped bean curd skin. The roller frame 207 straightens the bean curd skin, ensuring that the bean curd skin is smoothly fed into the discharge head 206.
[0054] Winding stage: The first drive motor 102 in the winding assembly 10 drives the turntable 103 to rotate. The sleeve 106 on the turntable 103 has a conical structure and a through slot 107. As the turntable 103 rotates, the bean curd skin pulled out by the discharge head 206 is clamped by the first clamping plate 109. The bean curd skin is wound around the sleeve 106 once, forming a preliminary winding structure.
[0055] Knotting stage: The third drive motor 304 in the knotting assembly 30 drives the eccentric cam 307 to rotate, and the eccentric cam 307 drives the guide rail 308 to move, causing the support frame 309 to move up and down. The support frame 309 drives the second clamping plate 310 to move to the point where the bean curd skin is wrapped, and the second control cylinder 311 controls the opening and closing of the second clamping plate 310 to tighten the bean curd skin to form a knot.
[0056] Cutting stage: The second adjusting cylinder 406 in the cutting assembly 40 adjusts the angle of the scissors 408, and the third control cylinder 407 drives the scissors 408 to close, cutting the knotted bean skin. After cutting, the scissors 408 open to prepare for the next cutting.
[0057] In this embodiment, the cut bean curd skin forms a complete knot, completing one knotting process, and automatically enters the next cycle, repeating the process of feeding, winding, knotting, and cutting.
[0058] Example 2
[0059] Based on the above embodiments, this embodiment further proposes a knotting process including the following steps:
[0060] Step 1: Each PLC control component performs a self-test;
[0061] The first drive motor 102, the second drive motor 203, the third drive motor 304, the first cylinder 104, and the first control cylinder 108 are reset to their initial positions.
[0062] Check that the shears 408 of the cutting assembly 40 are in the open position to ensure there is no interference.
[0063] The rolled strips of bean curd skin are placed in the feeding area of the feeding assembly 20. The bean curd skin is manually pulled by the end, passing through the rollers of the roller frame 207 in sequence, and finally passing out slightly from the discharge head 206.
[0064] After this stage is completed, it enters standby automatic cycle mode.
[0065] Step 2: Feeding and positioning;
[0066] The second drive motor 203 starts upon receiving a command, driving the ball screw 202 to rotate and precisely controlling the sliding frame 204 and the discharge head 206 to advance forward a predetermined distance. This distance determines the length of a single bean curd knot.
[0067] Meanwhile, the first adjusting cylinder 205 can be finely adjusted to ensure that the discharge head 206 delivers the bean curd skin to the preset clamping position of the winding assembly.
[0068] Step 3: Winding and shaping;
[0069] When the bean curd sheet is delivered to the designated position on the side of the sleeve 106, the first control cylinder 108 of the winding assembly 10 is activated, driving the first clamping plate 109 to close and firmly clamp the end of the bean curd sheet.
[0070] The first drive motor 102 starts, driving the turntable 103 and sleeve 106 to rotate at least 360 degrees, usually 370-400 degrees, to ensure reliable overlap.
[0071] During rotation, the bean skin is wrapped around the outer surface of the conical sleeve 106, forming a loose ring structure. The conical design of the sleeve 106 facilitates subsequent removal and knotting.
[0072] Step 4: Tie and tighten;
[0073] The third drive motor 304 of the tie assembly 30 starts, driving the eccentric cam 307 to rotate. Through the slider 306 and the slide bar 308 mechanism, the rotational motion is converted into the precise linear motion of the support frame 309 downward.
[0074] The support frame 309 drives the second clamping plate 310 to move downward, so that it can accurately extend into the inside of the sleeve through the slot 107 on the sleeve 106.
[0075] When the second clamping plate 310 moves to the area below the bean curd ring inside the sleeve 106, the second control cylinder 311 activates, driving the second clamping plate 310 to close and clamp the bean curd ring.
[0076] Subsequently, the first clamping plate 109 opens under the control of the first control cylinder 108, releasing the bean curd skin end. Immediately afterwards, the support frame 309 resets upward under the drive mechanism, and the second clamping plate 310 clamps the bean curd skin ring and moves upward, pulling the bean curd skin ring out of the sleeve 106 and tightening it, thereby forming a tight bean curd skin knot.
[0077] Step 5: Cutting and unloading;
[0078] After the knotting action is completed, the cutting assembly 40 begins to work. The second adjusting cylinder 406 extends and retracts, driving the third control cylinder 407 and the shears 408 at its end to move to the optimal cutting position, usually between the knot and the raw material strip.
[0079] The third control cylinder 407 activates, driving the scissors 408 to close quickly, cleanly and neatly cutting the knotted bean curd skin off the raw material belt.
[0080] In this embodiment, the cut bean curd sheets fall into a collection basket or conveyor belt under the action of gravity or an auxiliary conveying device, and proceed to the next process. The scissors 408 open, and all components return to their initial state. The next work cycle is immediately triggered, repeating from step 2 to achieve continuous automated production.
[0081] The control system allows for flexible settings of the sleeve rotation speed, feeding length, knotting force, and shear angle (30-60°) to adapt to bean curd skin raw materials of varying widths, thicknesses, and toughness, offering high versatility. The consistency and precision of the mechanical movements fundamentally ensure a high degree of uniformity in the size, shape, and tightness of each bean curd skin knot, resulting in stable and controllable product quality superior to manual operation. The fully automatic cycle eliminates intermittent stoppages caused by human factors, significantly improving production efficiency. Simultaneously, precise control reduces breakage losses of the bean curd skin during the winding and knotting process.
[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
