[0024] It should be further understood that the term “and / or” used in the specification and appended claims refers to any combination and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0025] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0026] Embodiment 1: like Figures 1 to 6 As shown, the present application provides an automatic tea packaging device, including a workbench 1 and an electric rotating disk 2 and a packaging bag heat sealing component 3 arranged on the workbench 1.

[0027] Through the distribution and configuration of the electric rotating disk 2, an automated process of multi-station continuous operation is realized, thereby increasing the packaging speed and reducing manual intervention.

[0028] The turntable of the electric rotating disk 2 is provided with a packaging bag loading station 21, a packaging bag heat sealing station 22 and a tea bag unloading station 23; wherein the packaging bag loading station 21 is provided with a clamping assembly 211, and the clamping assembly 211 is used to clamp the packaging bag containing tea leaves.

[0029] By arranging the clamping assembly 211 at the packaging bag loading station 21, automatic clamping and positioning of the tea packaging bags are realized, ensuring that the packaging bags can be accurately delivered to the next process.

[0030] The packaging bag heat-sealing component 3 is arranged at one side of the packaging bag heat-sealing station 22 and is used for heat-sealing the packaging bag containing tea leaves clamped by the clamping component 211 .

[0031] By precisely controlling the position and operation of the packaging bag heat-sealing assembly 3, the sealing performance of the packaging bag containing tea can be optimized, ensuring high quality and consistency of the heat-sealing effect.

[0032] The packaging bag heat sealing assembly 3 includes a mounting bracket 31 , a height adjustment member 32 , a heat sealing member 8 and a driving member 37 .

[0033] By comprehensively applying the mounting bracket 31, the height adjusting member 32 and the driving member 37, the height and pressure adjustment of the heat sealing member 8 can be achieved to adapt to packaging bags of different sizes and thicknesses, thereby improving the adaptability and quality of packaging.

[0034] The mounting bracket 31 is fixed on the workbench 1 , the height adjusting member 32 is arranged on the mounting bracket 31 , and the heat sealing member 8 is arranged on one side of the height adjusting member 32 , wherein the heat sealing member 8 includes a heat sealing space 81 .

[0035] Through the cooperation of the mounting bracket 31 and the height adjusting member 32, the heat sealing strip can be precisely adjusted in the vertical direction to adapt to the height change of the packaging bag, allowing the packaging bag to enter the heat sealing space 81 of the heat sealing member 8, thereby ensuring accurate alignment of the heat sealing area.

[0036] The driving member 37 is fixed on the mounting bracket 31 to drive the height adjusting member 32 to perform linear reciprocating motion along the first direction, and the heat sealing member 8 adjusts the spacing of the heat sealing space 81 to achieve heat sealing of the packaging bag containing tea leaves.

[0037] Through the precise control of the driving member 37, the synchronous action of the heat sealing member 8 is effectively coordinated, thereby improving the speed and effect of heat sealing, reducing the operation time and enhancing the uniformity of sealing.

[0038] The tea bag unloading station 23 is used to unload the packaging bags filled with tea leaves after heat sealing.

[0039] Through the design of the automatic unloading station, the packaging bags can be quickly removed and collected after heat sealing, which improves the continuous operation efficiency of the entire packaging line and reduces manual cleaning work.

[0040] In this embodiment, the electric rotating disk 2 on the workbench 1 clamps the packaging bag containing tea leaves from the packaging bag loading station 21 through the clamping assembly 211 and transfers it to the next station of the electric rotating disk 2, namely, the packaging bag heat sealing station 22. Here, the packaging bag heat sealing assembly 3 will perform heat sealing operation on the packaging bag on the clamping assembly 211 to ensure that the tea leaves are completely sealed. After the heat sealing is completed, the packaging bag is transferred to the tea bag unloading station 23 through the electric rotating disk 2, and finally the entire automated packaging process is completed.

[0041] Through the design of the mounting bracket 31, the height adjustment member 32 and the heat sealing member 8 of the packaging bag heat sealing assembly 3, the packaging bag containing tea can be accurately heat-sealed under different height and pressure requirements, which not only ensures the uniformity and sealing effect of the heat seal, but also avoids the problem of improper sealing caused by changes in the packaging height, solves the limitations of the traditional fixed heat sealing assembly, provides more flexible heat sealing operation to adapt to packaging bags of different sizes and shapes, and improves the problem that the height position of the packaging bag is easily changed when the packaging bag is heat-sealed, resulting in loose tea packaging. In addition, the automated workflow reduces manual operations, reduces production costs, and improves the degree of automation of the production line, making production more efficient and economical.

[0042] Embodiment 2: like Figures 1 to 6 As shown, the heat sealing member 8 includes a first clamping plate 33, a second clamping plate 34, a first heat sealing strip 35, and a second heat sealing strip 36; the first clamping plate 33 and the second clamping plate 34 are arranged on one side of the height adjusting member 32, the first heat sealing strip 35 is arranged on the first clamping plate 33, and the second heat sealing strip 36 is arranged on the second clamping plate 34; when the driving member 37 drives the height adjusting member 32 to descend or rise to a preset position, the first clamping plate 33 and the second clamping plate 34 move toward or relative to each other along the second direction.

[0043] By setting the first heat sealing strip 35 on the first clamping plate 33 and the second heat sealing strip 36 on the second clamping plate 34, when the driving member 37 drives the height adjusting member 32 to descend to the preset position, the first clamping plate 33 and the second clamping plate 34 drive the first heat sealing strip 35 and the second heat sealing strip 36 to move toward each other along the second direction, so as to achieve heat sealing of the packaging bag containing tea leaves.

[0044] When the driving member 37 drives the height adjusting member 32 to rise to the preset position, the first clamping plate 33 and the second clamping plate 34 drive the first heat sealing strip 35 and the second heat sealing strip 36 to move relative to each other along the second direction, and exit the state of heat sealing the packaging bag containing tea leaves.

[0045] Among them, the height adjustment member 32 includes a sleeve 321, a sliding rack 322, a telescopic block 323 and a bidirectional screw 324, and the driving member 37 includes a driving motor 371, a worm 371, a first worm gear 372, a second worm gear 373, a first transmission gear 374, a second transmission gear 375 and a driven gear 376.

[0046] Through the stable structure of the sleeve 321 and the adjustability of the sliding rack 322 combined with the dynamic adjustment of the telescopic block 323 and the bidirectional screw 324, high-precision position control and flexibility of the height adjustment member 32 are achieved, ensuring that the packaging bag heat sealing assembly 3 can adapt to packaging requirements of different heights and sizes.

[0047] The sleeve 321 is fixed on the mounting bracket 31, the sliding rack 322 is telescopically sleeved on the sleeve 321 along a first direction, the telescopic block 323 is connected to one end of the sliding rack 322 away from the sleeve 321, and the bidirectional screw 324 is rotatably penetrated on the telescopic block 323 along a second direction.

[0048] By fixing the sleeve 321 on the mounting bracket 31, the sliding rack 322 is allowed to be telescopically adjusted along the first direction. Combined with the rotation function of the bidirectional screw 324, fine adjustment of the height adjustment member 32 is achieved to adapt to the variable size and height requirements of the packaging bags in the packaging process.

[0049] The first clamping plate 33 is threadedly connected to one side of the bidirectional screw 324 , and the second clamping plate 34 is threadedly connected to the other side of the bidirectional screw 324 .

[0050] By threading the first clamping plate 33 and the second clamping plate 34 on different thread ends of the bidirectional screw 324 , when the bidirectional screw 324 rotates, the first clamping plate 33 and the second clamping plate 34 can move toward or relative to each other along the second direction.

[0051] like Figures 1 to 6 As shown, a first limiting rod 331 and a second limiting rod 332 are provided between the first clamping plate 33 and the telescopic block 323 , and the first limiting rod 331 and the second limiting rod 332 are used to limit the first clamping plate 33 .

[0052] The limiting functions of the first limiting rod 331 and the second limiting rod 332 ensure that the first clamping plate 33 moves stably along the second direction when moving on the bidirectional screw rod 324, thereby avoiding the problem of rotation of the first clamping plate 33.

[0053] A first guide rod 341 and a second guide rod 342 are provided between the second clamping plate 34 and the telescopic block 323 . The first guide rod 341 and the second guide rod 342 are used to guide the second clamping plate 34 .

[0054] The first guide rod 341 and the second guide rod 342 ensure the precise movement trajectory of the second clamping plate 34 when moving on the bidirectional screw 324, thereby enhancing the alignment accuracy and efficiency of the entire heat sealing operation.

[0055] The driving motor 371 is fixed on the mounting bracket 31 , and the worm 371 is connected to the output end of the driving motor 371 and rotates along the first direction.

[0056] Through the configuration of the driving motor 371 and the worm 371, efficient power transmission and control are achieved, providing a stable and reliable driving force for the entire heat sealing system.

[0057] The worm 371 includes a first driving section 3711, a toothless section 3712 and a second driving section 3713. The first worm wheel 372 is rotatably meshed on the first driving section 3711 along the second direction. The first transmission gear 374 is coaxially connected to the first worm wheel 372, the second transmission gear 375 is meshed with the first transmission gear 374, and the driven gear 376 is coaxially connected to the second transmission gear 375. The outer peripheral wall of the sleeve 321 is provided with an avoidance opening 3211, and the driven gear 376 is penetrated through the avoidance opening 3211 and meshed with the sliding rack 322; the second worm wheel 373 is coaxially connected to the bidirectional screw 324, and when the second worm wheel 373 is in the first state, the second worm wheel 373 slides on the toothless section 3712, and when the second worm wheel 373 is in the second state, the second worm wheel 373 is meshed with the second driving section 3713.

[0058] When the worm 371 is driven to rotate by the driving motor 371, the first driving section 3711 drives the first worm wheel 372 to rotate in the second direction. At this time, the first transmission gear 374 coaxially connected to the first worm wheel 372 rotates synchronously and drives the second transmission gear 375 to rotate. The second transmission gear 375 drives the driven gear 376 coaxially connected thereto to rotate, and the driven gear 376 drives the sliding rack 322 to perform a linear reciprocating motion in the sleeve 321, thereby achieving the effect of driving the sliding rack 322 to perform a linear reciprocating motion by the driving motor 371.

[0059] It should be noted that when the driving motor 371 rotates forward and drives the sliding rack 322 to descend in the first direction, the second worm gear 373 is in the first state and moves downward in the first direction on the toothless section 3712 of the worm 371. After the sliding rack 322 descends to a preset height, the second worm gear 373 is in the second state. At this time, the second worm gear 373 is engaged with the second driving section 3713 of the worm 371. Then, the second worm gear 373 drives the bidirectional screw 324 coaxially connected thereto to rotate. At this time, the first splint 33 and the second splint 34 threadedly connected to the bidirectional screw 324 move toward each other in the second direction, and the heat sealing area of ​​the packaging bag containing tea leaves is heat sealed by using the first heat sealing strip 35 arranged on the first splint 33 and the second heat sealing strip 36 arranged on the second splint 34.

[0060] When the heat sealing of the packaging bag containing tea leaves is completed, the motor reverses and drives the sliding rack 322 to rise in the first direction. At this time, the first clamping plate 33 and the second clamping plate 34 threadedly connected to the bidirectional screw 324 make relative movement in the second direction, and drive the first heat sealing strip 35 arranged on the first clamping plate 33 and the second heat sealing strip 36 arranged on the second clamping plate 34 to exit the heat sealing area. After the sliding rack 322 rises to a preset position in the first direction, the second worm gear 373 is disconnected from the second driving section 3713 of the worm 371, and the toothless section 3712 of the worm 371 moves upward in the first direction, that is, it returns from the second state to the first state, prepares for the next heat sealing, completes the heat sealing of the packaging bag once, and repeats this cycle.

[0061] By integrating the precise control and dynamic configuration of the drive motor 371, the worm 371, the worm wheel, the transmission gear and the bidirectional screw 324, the fully automated management of the heat sealing process of the packaging bag is achieved, which greatly improves the accuracy and efficiency of the heat sealing process. The system controls the vertical movement of the sliding rack 322 by the forward and reverse rotation of the drive motor 371, and accurately adjusts the rotation of the bidirectional screw 324 by coordinating the state switching of the second worm wheel 373 and the dynamic engagement of the worm 371, thereby controlling the relative movement of the first clamping plate 33 and the second clamping plate 34. It not only ensures that the heat sealing strip is accurately aligned and tightly sealed within the appropriate time, but also allows rapid evacuation after the heat sealing is completed, reducing the loss of heat energy and preventing excessive heat treatment of the packaging material. In addition, by utilizing the sliding and meshing action of the second worm gear 373 in the design of the toothless segment 3712, its operating state can be automatically adjusted in different working stages. By cleverly utilizing the precise coordination between mechanical transmissions, a dynamic closed-loop system is realized, so that the packaging bag can always maintain the best condition when being heat-sealed, avoiding poor sealing problems caused by height changes or uneven materials.

[0062] At the same time, the coordinated actions of various components are achieved through the single control of the drive motor 371, which simplifies the complexity of the entire system and significantly improves the operational reliability; the drive motor 371 provides a consistent power source through precise rotation output, and drives the worm 371 and the various transmission components meshing therewith in turn. The centralized control method reduces the equipment's dependence on multiple motors and controllers, reduces manufacturing and maintenance costs, and further reduces energy consumption, thereby improving efficiency and reducing operating errors, providing a high-efficiency, energy-saving and low-maintenance solution for the packaging line. like Figures 1 to 6 As shown, a packaging bag loading component 4 is arranged on one side of the packaging bag loading station 21, and the packaging bag loading component 4 includes a feeding accommodating member 41 and a flip clamping member 42. The feeding accommodating member 41 includes a feeding bracket 411, a conveyor belt 412 and a conveying motor 413. The feeding bracket 411 is fixed on the workbench 1, and the conveyor belt 412 and the conveying motor 413 are arranged on the feeding bracket 411. The conveying motor 413 drives the conveyor belt 412 to rotate and convey the packaging bag.

[0063] Through the precisely controlled conveying system, efficient and continuous conveying of packaging bags can be achieved, ensuring that each packaging bag can reach the working position in a timely and correct manner, thereby improving the smoothness and efficiency of the entire packaging process.

[0064] The flip clamp 42 includes a loading bracket 421 , a loading cantilever bracket 422 , a rotating block 423 , a clamping fixture 424 and a flip cylinder 425 .
