[0031] The following further describes the present utility model in detail with reference to the drawings.

[0032] A tea cake packaging machine, as Figures 1-3As shown in the figure, it includes an electrical component chassis cabinet 1, a tea cake sorting device 2, a tea cake conveying device 3, a packaging bag conveying device 4, a limit control device 5, and a packaging device 6. The tea cake sorting device 2, the tea cake conveying device 3, the packaging bag conveying device 4, and the packaging device 6 are all installed on the top of the electrical component chassis cabinet 1 and supported by the electrical component chassis cabinet 1. At the same time, the control and power supply lines of the tea cake sorting device 2, the tea cake conveying device 3, the packaging bag conveying device 4, and the packaging device 6 are all led to the inside of the electrical component chassis cabinet 1 for connection to achieve integrated circuit control. The tea cake sorting device 2 and the packaging bag conveying device 4 are distributed left and right. Among them, the tea cake sorting device 2 is a vibrating disk, which is used to sort and arrange the disordered tea cakes, and the packaging bag conveying device 4 is used to batch wind and transport the packaging bags for packaging the tea cakes. The tea cake conveying device 3 is arranged between the tea cake sorting device 2 and the packaging bag conveying device 4, and is used to continue to convey the tea cakes sorted by the tea cake sorting device 2, and enable the tea cakes to converge equidistantly with the packaging bags conveyed by the packaging bag conveying device 4. The packaging device 6 is arranged at the intersection of the tea cakes and the packaging bags, and the packaging device 6 closes and cuts the packaging bags to complete the packing operation.

[0033] It should be noted that in this embodiment, the tea cake sorting device 2 is a vibrating feeding tray, and the packaging device 6 is a prior art, and neither of them is the technical point improved in this application. Therefore, no further description will be given.

[0034] Specifically, the tea cake sorting device 2 sorts and transports the tea cakes to be packaged through the vibration principle. The tea cake conveying device 3 is located at the output end of the tea cake sorting device 2 to receive the tea cakes sorted by the tea cake sorting device 2, and the sorted tea cakes are uniformly conveyed through the tea cake conveying device 3. The limit control device 5 is installed on the conveying path of the packaging bag, and the limit control device 5 is in contact with the packaging bag, and senses the tightness of the packaging bag under the action of gravity or the pressure of the packaging bag. The limit control device 5 controls the conveying speed of the packaging bag conveying device 4 according to the tightness of the packaging bag. The conveyed tea cakes and packaging bags are all led to the inside of the packaging device 6, and the mechanical components inside the packaging device 6 fold, seal, and cut the packaging bags to achieve the packing of the tea cakes.

[0035] In one specific embodiment, such as Figures 2-4As shown in the figure, the packaging bag conveying device 4 includes a support frame 401, a driving motor 402, a packaging bag feeding tray 403, a first guiding roller 404, and a second guiding roller 405. The support frame 401 is used to support the driving motor 402, the packaging bag feeding tray 403, and the first guiding roller 404. After being powered on, the driving motor 402 can drive the packaging bag feeding tray 403 to rotate, so that the packaging bags on the surface of the packaging bag feeding tray 403 can be conveyed. The first guiding roller 404 is arranged on the side of the packaging bag feeding tray 403, and the second guiding roller 405 is installed at the lower part of the support frame 401, and the second guiding roller 405 is located directly above the packaging device 6. Specifically, both the first guiding roller 404 and the second guiding roller 405 are used to guide the packaging bag, so that the packaging bag is in a taut state, avoiding loosening of the packaging bag during the conveying process.

[0036] On the basis of the above embodiment, a number of adjustment mounting holes 406 are provided on the support frame 401, and the adjustment mounting holes 406 are runway-shaped holes. The adjustment mounting holes 406 for installing the first guiding roller 404 are horizontally arranged, and the adjustment mounting holes 406 for installing the second guiding roller 405 are vertically arranged. Both the first guiding roller 404 and the second guiding roller 405 are installed inside the adjustment mounting holes 406 through bolts, and the installation positions of the first guiding roller 404 and the second guiding roller 405 can be adjusted according to the production requirements to adjust the conveying path of the packaging bag.

[0037] It should be noted that the number of the first guiding rollers 404 is two, and the two first guiding rollers 404 are horizontally arranged, so as to increase the turning angle during the conveying process of the packaging bag and avoid an excessive turning angle of the packaging bag, which may lead to an increase in the torque required for driving.

[0038] In one specific embodiment, as Figures 2-3 shown, the limit control device 5 includes a limit trigger 501, a trigger shaft disc 502, and a limit rod 503. Both the limit trigger 501 and the trigger shaft disc 502 are arranged on the support frame 401. Among them, switches are respectively arranged on both sides of the bottom of the limit trigger 501, which can respectively output start-up and shutdown signals. The limit rod 503 is arranged on the trigger shaft disc 502. Under the action of gravity or the pressure of the packaging bag, the limit rod 503 drives the trigger shaft disc 502 to rotate to respectively trigger the switches at the bottom of the limit trigger 501, realizing the output of start-up or shutdown signals. The signals sent by the limit trigger 501 are transmitted to the driving motor 402 through wires, used to control the start-up and shutdown of the driving motor 402, and further control the conveying speed of the packaging bag.

[0039] On the basis of the above embodiments, a notch is provided on one side of the trigger disc 502 facing the limit trigger 501, and the edge of the notch abuts against the trigger switch of the limit trigger 501 after the trigger disc 502 rotates. This is to enable different switches to be triggered when the trigger disc 502 rotates left and right.

[0040] It should be noted that the end of the limit rod 503 is L-shaped, and the end of the limit rod 503 presses down on the packaging bag from inside the packaging bag. Setting the end of the limit rod 503 to be L-shaped can increase the contact area with the packaging bag and also increase the weight of the end of the limit rod 503, enabling the end of the limit rod 503 to better press on the packaging bag; while the limit rod 503 is slidably mounted on the trigger disc 502, the installation position of the limit rod 503 and the trigger disc 502 can be changed, thereby changing the length of the force arm of the limit rod 503, and further adjusting the control of the conveying tightness of the packaging bag by the limit rod 503.

[0041] The working process and beneficial effects of the present utility model are as follows: During operation, the limit rod 503 applies a downward pressure on the packaging bag from above under the action of gravity. When the packaging bag is too loose, the limit rod 503 drives the trigger disc 502 to rotate and trigger the shutdown switch of the limit trigger 501, sending a shutdown signal to the drive motor 402 to prevent the continuous conveyance of the packaging bag. When the packaging bag is too tight, the limit rod 503 drives the trigger disc 502 to rotate and trigger the startup switch of the limit trigger 501, sending a startup signal to the drive motor 402 to increase the conveying speed of the packaging bag, achieving the effect of automatically controlling the input volume of the packaging bag.

[0042] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present utility model shall be included within the protection scope of the present utility model.
