DETAILED DESCRIPTION

[0016] Reference Figures 1 to 4The packaging belt switching mechanism shown in the figure includes a multi-station rotating frame 1 for placing packaging belts 2. In this embodiment, there are six stations to prevent six packaging belts 2. The multi-station rotating frame 1 is equipped with a driving device to control the rotation of the multi-station rotating frame 1 to switch the packaging belts 2. Such a design can quickly and automatically complete the switching of the packaging belts 2, reducing the time and workload of manually replacing the packaging belts 2, thereby improving the working efficiency of the entire production line.

[0017] A plurality of mold release mechanisms are arranged on the periphery of the multi-station rotating frame 1, and these mold release mechanisms can stably fix the packaging belt 2 on the multi-station rotating frame 1, thereby ensuring the accurate positioning and smooth transition of the packaging belt 2 during the switching process.

[0018] As a preferred embodiment, the driving device is configured to include a motor 4 and a cylindrical gear 401 arranged on the main shaft of the motor 4, and a ring gear 101 meshed with the cylindrical gear 401 is arranged on the multi-station rotating frame 1. Such a design can not only realize the precise rotation of the multi-station rotating frame 1, but also improve the switching efficiency and stability of the packaging belt 2. Specifically, the cylindrical gear 401 is located on the main shaft of the motor 4, and as the power output part of the motor 4, it is responsible for transmitting power to the multi-station rotating frame 1. The ring gear 101 is installed on the multi-station rotating frame 1, meshed with the cylindrical gear 401, and together constitutes a transmission chain. Through this design, we can use the high transmission accuracy and large transmission torque of the cylindrical gear 401 to realize the high-speed and stable rotation of the multi-station rotating frame 1. At the same time, due to the meshing of the ring gear 101 and the cylindrical gear 401, accurate positioning and power transmission can be achieved between them, so that the multi-station rotating frame 1 always maintains precise position control during the rotation process, thereby realizing efficient and stable switching of the packaging belt 2.

[0019] As a preferred embodiment, in order to ensure the accurate positioning of each station, we set a corresponding positioning hole 102 for each station on the side of the multi-station rotating frame 1. At the same time, a positioning pin 501 driven by the cylinder 5 is also provided. This positioning hole 102 cooperates with the positioning pin 501. After the multi-station rotating frame 1 stops, the positioning pin 501 is inserted into the positioning hole 102 under the drive of the cylinder 5, which greatly improves the stability of the multi-station rotating frame 1 and avoids the problems of misalignment and jamming of the packaging belt 2.

[0020] As a preferred embodiment, the mold release mechanism includes a material tray 6, and the material tray 6 is provided with a detachable support plate 601 to facilitate the installation of the packaging belt 2. A tensioning plate 7 pushed by a spring is provided on the side of the material tray 6. Under the push of the spring, the tensioning plate 7 can be pressed against the packaging belt 2. The tensioning plate 7 mainly provides additional support force. When the packaging belt 2 is installed on the material tray 6, if the position of the packaging belt 2 is maintained only by the gravity and friction of the material tray 6 itself, it may be displaced due to the weight of the packaging belt 2 or the inclination of the material tray 6. By setting the tensioning plate 7, we can use the additional force provided by the spring to further ensure the stability of the mold roll and avoid its displacement during the processing. At the same time, it also provides a certain damping to achieve continuous and stable supply of the packaging belt 2, ensure the continuity of the packaging operation, and prevent the packaging belt 2 from being fast or slow, thereby improving efficiency and quality. On this basis, a head damping plate 8 pressed by a spring is provided on the side of the material tray 6, and the head of the packaging belt 2 is clamped on the head damping plate 8 after being pulled. This design can further provide an additional resistance to the packaging belt 2, making the movement of the packaging belt 2 more stable, and can also fix the head of the packaging belt, so that the head of the packaging belt 2 can be found quickly and conveniently after switching the packaging belt 2.

[0021] Specifically, the above-mentioned material tray 6 includes a fixed plate 602 and a roller shaft 603 arranged in the middle, and a plurality of positioning columns 604 are arranged around the roller shaft 603, wherein the ends of some positioning columns 604 have sharp corners, and the ends of some positioning columns 604 are provided with screw holes, and a plurality of mounting holes 601a are correspondingly provided on the support plate 601. During installation, the packaging belt 2 is first fixed by the roller shaft 603, and then it can be quickly fixed on the positioning column 604 by means of the positioning column 604 with a sharp corner, and then it is connected to the positioning column 604 with a screw hole by bolts to fix the support plate 601.

[0022] Specifically, a movable shaft 701 is provided behind the tensioning plate 7, and the movable shaft 701 is installed on an axle seat 702, and a tensioning plate spring 703 is provided between the tensioning plate 7 and the axle seat 702. The cooperation between the axle seat 702 and the movable shaft 701 can ensure that the movement of the tensioning plate 7 will not deviate, and a blocking plate 704 can be provided at the tail of the movable shaft 701, the purpose of which is to prevent the movable shaft 701 from being separated from the axle seat 702, and to set some monitoring and feedback mechanisms on the blocking plate 704. For example, when the mold roll is almost used up, the tensioning plate 7 moves a long distance, and the feedback to the blocking plate 704 is that it is very close to the axle seat 702. If a proximity sensor is added, the feedback of the proximity sensor can be used to allow the system to receive this signal, indicating that the packaging belt 2 has been used up and needs to be switched. This not only improves the automation level of production, but also increases the continuity and stability of production, and greatly improves production efficiency.

[0023] Specifically, a fixed bottom plate 801 is provided in cooperation with the above-mentioned head damping plate 8. The head damping plate 8 is provided on one side of the fixed bottom plate 801 and is rotatably fixed on the multi-station rotating frame 1. A head plate spring 802 is provided at its tail end. The head plate spring 802 is a tension spring. One end of the head damping plate 8 is provided with a hook fixedly connected to the head damping plate 8, and the other end is provided with a hook fixed to a spring frame 803 provided on the side. Under the action of the tension spring, the head damping plate 8 is pressed downward toward the fixed bottom plate 801, and the head of the belt passes through the head damping plate 8 and the fixed bottom plate 801 and is clamped between the two. Such a design can ensure that the head damping plate 8 can rotate flexibly on the multi-station rotating frame 1, and because a spring is used to provide a clamping force, the head damping plate 8 can better adapt to packaging belts 2 of different thicknesses.
