Description

Technical Field

[0001] This invention relates to the field of tea processing technology, specifically to a fully automatic tea cake bundling device. Background Technology

[0002] Tea cakes, as a common type of compressed tea product (such as Pu-erh tea cakes and white tea cakes), typically require bundling and packaging after production and processing to facilitate transportation, storage, and sales. Currently, bamboo strips or bamboo stalks are commonly used for bundling tea cakes. The tea cakes are manually wrapped, tightened, and secured to form an external support package with a certain structural strength. This traditional process is still widely used in some small and medium-sized tea enterprises and workshops, offering advantages such as low cost and natural, environmentally friendly materials. However, it relies heavily on manual experience, has a low degree of automation, and limited production efficiency.

[0003] However, existing methods of bundling tea cakes mainly rely on manual labor, requiring highly skilled operators who need extensive training to master the process, resulting in high labor costs and difficulty in recruiting skilled workers. Furthermore, the bundling process involves repeated bending and tightening of bamboo strips, which is physically demanding, and the sharp edges of the bamboo strips can easily cut the operators' hands, posing a safety hazard. In addition, when clamping and bundling the tea cakes, operators often need to step on them to secure them, which is not only unprofessional and physically demanding but also fails to meet hygiene and safety requirements in food packaging. Therefore, there is an urgent need for a fully automated tea cake bundling device that can replace manual labor, reduce labor intensity, improve production efficiency, and comply with food safety regulations. Summary of the Invention

[0004] The purpose of this invention is to provide a fully automatic tea cake bundling device, which solves the problems of high labor intensity, low efficiency, safety hazards, and failure to meet food hygiene requirements caused by the reliance on manual operation for bundling existing tea cakes.

[0005] The present invention solves the above-mentioned technical problems through the following technical solutions, the present invention comprising: Control panel; A fixed cylinder is installed on the upper side of the operating table and is used to hold tea cakes; The clamping mechanism is installed on the upper side of the operating table; The lifting mechanism is installed at the bottom of the operating table and corresponds vertically to the fixed cylinder. It is used to lift the tea cake to adjust its height. The left and right bamboo strip tightening mechanisms are installed on the upper side of the operating table and are located on both sides of the clamping mechanism, respectively, to tighten the bamboo strips tied to the outside of the tea cake. The control panel is electrically connected and signal-transmitted to the clamping mechanism and lifting mechanism.

[0006] Preferably, the clamping mechanism includes a fixed clamping plate fixedly installed on the operating table, and a movable clamping plate slidably installed on the operating table and disposed opposite to the fixed clamping plate; A clamping rod motor is installed on the operating table, and the telescopic end of the clamping rod motor is fixedly connected to the movable clamping plate.

[0007] Preferably, a first fixed seat is fixed on the operating table and a second fixed seat is slidably installed thereon; a first sliding seat for fixing the fixed clamp is vertically slidably installed on the first fixed seat, and a second sliding seat for fixing the movable clamp is vertically slidably installed on the second fixed seat, and both the first sliding seat and the second sliding seat are locked by bolts.

[0008] Preferably, the lifting mechanism includes a lifting rod motor fixed to the bottom of the operating table, and the telescopic end of the lifting rod motor is fixed with a base plate for supporting the tea cake. A through hole is provided on the operating table inside the fixed cylinder, and the base plate is located in the through hole.

[0009] Preferably, a vertical guide rod is fixed to the bottom of the base plate, and the bottom of the vertical guide rod has a sensing part; a vertical slide rail is fixed to the bottom of the operating table, and two sliders are vertically slidably mounted on the vertical slide rail, and a second contact sensor for cooperating with the sensing part is respectively mounted on the two sliders.

[0010] Preferably, the left bamboo strip tightening mechanism and the right bamboo strip tightening mechanism have the same structure and are symmetrically arranged. The mechanism includes a fixture mounted on the operating table. A horizontal pendulum is rotatably mounted on the upper end of the fixture. A rotating seat is rotatably mounted on the horizontal pendulum via a ratchet and pawl structure. A tightening wheel is fixed on the upper surface of the rotating seat. A slot is provided on the tightening wheel. An outer cylinder is rotatably mounted on the outer side of the rotating seat. A second pawl is rotatably mounted on the inner wall of the outer cylinder. The second pawl is driven to rotate by a torsion spring. A tightening handle is fixed on the outer side of the outer cylinder.

[0011] Preferably, a longitudinally sliding block is mounted on the operating table, and a transversely sliding block is mounted on the longitudinally sliding block, with the fixture mounted on the transversely sliding block.

[0012] Preferably, a bamboo strip soaking tube is fixedly placed on one side of the operating table, and the end of the bamboo strip soaking tube penetrates through the operating table for soaking and treating the bamboo strips.

[0013] Preferably, both the fixed clamping plate and the movable clamping plate are arc-shaped structures adapted to the outer diameter of the tea cake, and are symmetrically arranged with respect to the radial line of the fixed cylinder.

[0014] This invention also proposes a fully automatic tea cake bundling method, implemented based on the aforementioned fully automatic tea cake bundling equipment, comprising the following steps: Step 1: Place multiple tea cakes, stacked and wrapped in outer packaging paper, on the base plate; Step 2: Use a clamping mechanism to hold the lower tea cake in place to secure multiple tea cakes, ensuring that the top tea cake is not covered. Step 3: Wrap the soaked flexible bamboo strips around the outside of the top layer of tea cake, and insert the two ends of the bamboo strips into the slots on the tightening wheels of the left and right bamboo strip tightening mechanisms, respectively. Step 4: By repeatedly turning the handle to tighten it, the ratchet and pawl structure is used to gradually tighten the bamboo strips, thus completing the binding of the current tea cake; Step 5: Loosen the clamping mechanism and lift multiple tea cakes upwards by the lifting mechanism to the height of one tea cake, so that the next tea cake is exposed; Step 6: Repeat steps 2 to 5 above until all tea cakes are bundled. Step 7: Finally, release the clamping mechanism, and the lifting mechanism will continue to lift, completely pushing out the bundled tea cake.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Through the coordinated operation of the clamping mechanism and the lifting mechanism, the automatic clamping and layer-by-layer lifting of the tea cake is achieved, eliminating the need for repeated manual support or position adjustment during the bundling process. This significantly reduces the complexity of operation and labor intensity, while also reducing reliance on the operator's experience. This facilitates standardized operations and improves overall production efficiency and operational stability.

[0016] 2. By setting up a symmetrical bamboo strip tightening mechanism and using a ratchet and pawl structure to achieve unidirectional progressive tightening, the bamboo strip tightening process is made more uniform and controllable, avoiding the problem of uneven or loose manual tightening, thereby improving the firmness and appearance consistency of the tea cake binding and enhancing product quality.

[0017] 3. This invention uses a mechanical clamping and tightening structure to replace traditional manual operation. Operators do not need to directly contact the sharp edges of the bamboo strips, effectively avoiding safety risks such as scratches. At the same time, it reduces high-intensity repetitive labor, improves the working environment, and enhances the safety and ergonomics of the equipment.

[0018] 4. The tea cake is fully restrained and supported by the fixed cylinder, clamping plate and base plate, avoiding the situation of stepping on or touching the tea cake by hand in the traditional binding process. This effectively prevents human contamination, meets the hygiene and safety requirements in the food processing process, and improves the applicability and compliance of the product in the food industry.

[0019] 5. By setting up a multi-directional adjustable structure (including clamp height adjustment and two-dimensional movement adjustment of the tightening mechanism), the equipment can be adapted to tea cakes of different diameters, thicknesses and binding positions, improving the versatility and flexibility of the equipment and reducing the time cost caused by equipment replacement or manual adjustment.

[0020] 6. By using the lifting mechanism to lift layer by layer and operate in a cyclic manner, multiple tea cakes can be loaded and continuously bundled at once, reducing frequent loading and unloading operations, improving batch processing capacity, and making it particularly suitable for large-scale production scenarios, thereby significantly improving overall production efficiency and automation level.

Detailed Implementation

[0023] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings. Example 1

[0024] This embodiment provides a technical solution: a fully automatic tea cake bundling device, such as... Figures 1-6 As shown, it includes an operating table 1, which is the supporting foundation structure of the whole machine, and is preferably made of stainless steel or other materials.

[0025] A mounting position is provided in the middle of the operating table 1, and a fixing cylinder 4 is fixedly installed in the mounting position. The fixing cylinder 4 is a hollow cylindrical structure used to place the tea cake 100 and to radially limit the tea cake 100. The fixing cylinder 4 is slidably installed on the operating table 1 through a self-locking slide rail slider structure 41, so that the fixing cylinder 4 has a longitudinal adjustment function.

[0026] A clamping mechanism 5 is provided on the operating table 1 to clamp and fix the tea cake 100. A lifting mechanism 3 is provided at the bottom of the operating table 1. The lifting mechanism 3 is located directly below the fixing cylinder 4 and lifts the tea cake 100. The lifting mechanism 3 adjusts the height of the tea cake 100 placed in the fixing cylinder 4. A left bamboo strip tightening mechanism 601 and a right bamboo strip tightening mechanism 602 are provided on one side of the fixing cylinder 4 to tighten the bamboo strips tied to the outside of the tea cake 100.

[0027] A control panel 2 is fixedly installed on one side of the control panel 1. The control panel 2 is connected to the electrical components and signal transmission in each actuator to control the operation of the whole machine.

[0028] A bamboo strip soaking tube 7 is fixedly placed on one side of the operating table 1. The end of the bamboo strip soaking tube 7 passes through the operating table 1. The position where it passes through the operating table 1 is preferably on the right side of the operator, so as to facilitate the operator's operation. The bamboo strip soaking tube 7 is used to soak and treat bamboo strips.

[0029] The clamping mechanism 5 includes a fixed clamping plate 53 fixedly installed on the operating table 1 and a movable clamping plate 58 slidably installed on the operating table 1. The fixed clamping plate 53 and the movable clamping plate 58 are symmetrically arranged along the radial line of the fixed cylinder 4. The external structure of the fixed clamping plate 53 and the movable clamping plate 58 is an arc-shaped structure adapted to the outer diameter of the tea cake 100 to ensure that the tea cake 100 can be firmly clamped. A clamping rod motor 54 is fixed on the operating table 1 via a first mounting seat, and the telescopic end of the clamping rod motor 54 is fixed to the movable clamping plate 58, thereby driving the movable clamping plate 58 to move.

[0030] The outer side of the fixed cylinder 4 is provided with a first fixed seat 51 fixed to the operating table 1 and a second fixed seat 56 slidably mounted on the operating table 1. The first fixed seat 51 and the second fixed seat 56 are symmetrically arranged. A first sliding seat 52 is vertically slidably mounted on the first fixed seat 51, and a second sliding seat 57 is vertically slidably mounted on the second fixed seat 56, both of which are locked by bolts. A fixed clamp 53 is fixed to one side of the first sliding seat 52, and the fixed clamp 53 faces the fixed cylinder 4. A movable clamp 58 is fixed to one side of the second sliding seat 57, and the movable clamp 58 is arranged opposite to the fixed clamp 53. The height of the fixed clamp 53 and the movable clamp 58 can be adjusted by adjusting the height of the first sliding seat 52 and the second sliding seat 57.

[0031] A horizontal guide rod 55 is fixedly installed on the second fixed seat 56. The horizontal guide rod 55 slides through the first mounting seat to increase the stability of the second fixed seat 56 when it moves.

[0032] A first contact sensor 59 is installed on one side of the second fixed base 56 and mounted on the operating table 1. When the movable clamping plate 58 is moved into place, the second fixed base 56 approaches the first contact sensor 59 to detect the clamping state, so as to transmit the signal of the clamping rod motor 54 retracting into place to the control panel 2.

[0033] The left bamboo strip tightening mechanism 601 and the right bamboo strip tightening mechanism 602 have the same structure but are symmetrically arranged, located on both sides of the clamping mechanism 5. Each includes a fixture 65 mounted on the operating table 1. A horizontal pendulum 66 is horizontally rotatably mounted on the upper end of the fixture 65. Specifically, one end of the horizontal pendulum 66 rotates with the fixture 65, and the other end of the horizontal pendulum 66 is unidirectionally rotatably mounted on a rotating seat 68 via a ratchet and pawl structure 67. The ratchet and pawl structure 67 specifically includes a ratchet fixed to the outside of the rotating seat 68 and a first pawl rotatably mounted on the horizontal pendulum 66. Furthermore, the engagement of the first pawl with the ratchet restricts the rotating seat 68 to rotate only to one side. A tightening wheel 61 is fixed on the upper surface of the rotating seat 68. The tightening wheel 61 has a slot for holding the bamboo strip to tighten it. An outer cylinder 621 is rotatably installed on the outside of the rotating seat 68. A second pawl 622 is rotatably installed on the inner wall of the outer cylinder 621. Both the first pawl and the second pawl 622 are driven to rotate by a torsion spring, and the rotation direction is towards the ratchet. A tightening handle 62 is fixed on the outside of the outer cylinder 621.

[0034] First, by rotating the horizontal pendulum 66, the inner end of the horizontal pendulum 66 is brought close to the tea cake 100. Then, the two ends of the bamboo strip are inserted into the slots. When the operator turns the tightening handle 62 to the designated side, the second pawl 622 will drive the tightening wheel 61 to rotate to that side, which will tighten the bamboo strip a little. When the tightening handle 62 is turned in the opposite direction, due to the mechanical characteristics of the ratchet and pawl structure 67, the rotating seat 68 and the tightening wheel 61 will not reverse and will be self-locked. The outer cylinder 621 is turned to the designated side again, and so on, thereby tightening the bamboo strip step by step.

[0035] Furthermore, in order to achieve position adjustment of the tightening wheel 61, a longitudinal moving block 64 is slidably arranged on the operating table 1, and a transverse moving block 63 is slidably arranged on the longitudinal moving block 64. The fixture 65 is fixed on the transverse moving block 63 to achieve two-dimensional displacement of the tightening wheel 61 in the horizontal direction. Both the longitudinal moving block 64 and the transverse moving block 63 can be fixed by bolts.

[0036] The specific operation of this embodiment is as follows: The operator places multiple tea cakes 100 to be bundled on the bottom plate 32 inside the fixed cylinder 4 by stacking them, and wraps the multiple tea cakes 100 with outer packaging paper.

[0037] The clamping rod motor 54 is activated, which drives the movable clamping plate 58 to move horizontally along the horizontal guide rod 55 towards the fixed clamping plate 53, thereby pressing the outer packaging paper together to fix the multiple tea cakes 100 in a basic way. At this time, the movable clamping plate 58 and the fixed clamping plate 53 press against the second layer of tea cakes 100, and the tea cake 100 on the top layer will not be covered by the movable clamping plate 58 and the fixed clamping plate 53.

[0038] After soaking, the flexible bamboo strips are wrapped around the outside of the top tea cake 100 (which is not covered by the clamping mechanism), and the two ends of the bamboo strips are tied together. The two ends of the bamboo strips are then inserted into the slots of the left bamboo strip tightening mechanism 601 and the right bamboo strip tightening mechanism 602, respectively. Then, by turning the rotating seat 68 little by little by turning the tightening handle 62, the bamboo strips will be tightened.

[0039] After the first tea cake 100 is bundled, the clamping rod motor 54 is activated to retract, and the lifting mechanism 3 drives the tea cake 100 to move upward, thereby lifting multiple tea cakes 100 to rise synchronously, so that the next tea cake 100 is exposed.

[0040] Then repeat the above steps until all 100 tea cakes are bundled together.

[0041] After the binding is completed, the clamping rod motor 54 reverses its movement, causing the movable clamping plate 58 to move away from the fixed clamping plate 53, releasing the constraint on the tea cake 100; at the same time, the lifting mechanism 3 continues to lift upward, completely pushing the bound tea cake 100 out of the fixed cylinder 4, making it easy for operators or subsequent robotic arms to remove. Example 2

[0042] This embodiment is a further optimization based on Embodiment 1. The parts that are the same as those described above will not be repeated here. Figure 3 and Figure 4 As shown, to further better realize the present invention, the following configuration is specifically adopted: In this embodiment, the lifting mechanism 3 includes a lifting rod motor 31 fixed to the bottom of the operating table 1 via a second mounting base. A through hole is provided on the operating table 1, which is located inside the fixed cylinder 4. A base plate 32 is fixed to the telescopic end of the lifting rod motor 31, and the base plate 32 fills the through hole. The tea cake 100 will be placed on the base plate 32. When the telescopic end of the lifting rod motor 31 is extended, the tea cake 100 can be moved upward.

[0043] A vertical guide rod 33 is fixed at the bottom of the base plate 32. The bottom of the vertical guide rod 33 has an outwardly protruding sensing part. A vertical slide rail 35 is fixed at the bottom of the operating table 1. Two sliders 36 are vertically slidably mounted on the vertical slide rail 35. The two sliders 36 can be fixed to the vertical slide rail 35 by bolts, thereby adjusting the position of the two sliders 36. A second contact sensor 34 is installed on each of the two sliders 36. When the lifting rod motor 31 moves to the lowest or highest stroke, the sensing part corresponds to the second contact sensor 34 located on the lower or upper side, respectively.

[0044] The above are merely preferred embodiments of the present invention and are illustrative in nature, not restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.
