Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, and more specifically, to an adjustable packaging machine. Background Technology

[0002] Currently, automated packaging equipment is widely used in the packaging process of various products, especially in the food, pharmaceutical, and daily chemical industries. As crucial equipment for automatically wrapping, sealing, and conveying products, packaging machines play a vital role in improving production efficiency and ensuring packaging quality.

[0003] Traditional packaging machines typically have a fixed structure, designed for packaging material rolls of specific sizes or specifications. They lack good adjustability and cannot adapt to the need for changing packaging material rolls of different sizes. When changing packaging material rolls, misalignment may occur during transport, affecting packaging quality and production efficiency. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model provides an adjustable packaging machine with the advantage of being able to position material rolls of different sizes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable packaging machine, including a base, a bracket fixedly connected to one side of the base, an unwinding roller fixedly connected to one side of the bracket, a conveying mechanism mounted on the other side of the bracket, a circumferential groove formed on the outer wall of the unwinding roller, an electric telescopic rod fixedly connected to one end of the inner wall of the unwinding roller, a fixing block fixedly connected to the output end of the electric telescopic rod, a motor fixedly connected inside the fixing block, a screw fixedly connected to the output end of the motor, a fixing cylinder fixedly connected to the middle of one side of the fixing block, and the outer wall of the screw rotatably connected to... On the inner wall of the fixed cylinder, a fixed sleeve is fixedly connected to one side of the outer wall of the fixed cylinder, and a threaded sleeve is threadedly connected to one side of the outer wall of the screw. A first fixed frame is fixedly connected to the outer wall of the fixed sleeve, and a second fixed frame is fixedly connected to the outer wall of the threaded sleeve. A first connecting plate is rotatably connected to the inner side of the first fixed frame, and a second connecting plate is rotatably connected to the inner side of the second fixed frame. The first and second connecting plates are arranged crosswise and connected by a connecting rod. An adjusting plate is installed on one side of the first and second connecting plates. The outer wall of the adjusting plate is slidably connected to the inner wall of the slide groove, and a clamping plate is fixedly connected to the surface of the adjusting plate.

[0006] As a preferred embodiment of the present invention, the conveying mechanism includes a tensioning component, a conveying component, and a conveying shaft. The tensioning component is installed on the lower part of one side of the support, the conveying component is installed on the upper part of one side of the support, and the conveying shaft is installed on one side of the surface of the base.

[0007] As a preferred embodiment of this utility model, a controller is fixedly connected to the other side of the surface of the bracket.

[0008] As a preferred embodiment of this utility model, a pressure roller is rotatably connected to the center of the front side of the bracket.

[0009] As a preferred embodiment of the present invention, the tensioning assembly includes a mounting frame, one side of which is fixedly connected to the lower part of one side of the support, and a tensioning roller is rotatably connected to the inner side of the mounting frame.

[0010] As a preferred embodiment of the present invention, the conveying assembly includes a support frame, one side of which is fixedly connected to the upper part of one side of a bracket, and a conveying roller is rotatably connected to the inner side of the support frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention uses a drive motor to rotate a screw, which in turn moves a screw sleeve and a fixing frame, thereby moving a connecting plate. With the help of a connecting rod, the connecting plate on the fixing frame moves accordingly, allowing the adjusting plate to open outwards and move the clamping plate out of the slide groove. Then, the electric telescopic rod is activated to move the fixing block, which in turn moves the clamping plate within the slide groove, causing its surface to press against one end of the material roll. This achieves compatibility with multiple specifications of materials and avoids the problem of misalignment during operation caused by the lack of adjustment function for materials of different sizes.

A connecting plate 14 is rotatably connected to the inner side of the fixed bracket 12. A connecting plate 2 15 is rotatably connected to the inner side of the fixed bracket 2 13. The connecting plate 14 and the connecting plate 2 15 are arranged crosswise and connected by a connecting rod 16. An adjusting plate 17 is installed on one side of the connecting plate 14 and the connecting plate 2 15. The outer wall of the adjusting plate 17 is slidably connected to the inner wall of the slide groove 4. A clamping plate 18 is fixedly connected to the surface of the adjusting plate 17.

[0021] In this embodiment, packaging film or thin film material is sleeved on unwinding roller 3. Unwinding roller 3 has a groove 4 on its outer wall for guidance. Then, motor 7 in fixing block 6 is started. Motor 7 drives screw 8 to rotate. Screw 8 drives screw sleeve 11 connected to it to move. Screw sleeve 11 drives fixing frame 2 13 to move laterally, thereby driving connecting plate 2 15 to move. With the cooperation of connecting rod 16, connecting plate 14 connected to fixing frame 1 12 can move in linkage. Adjusting plate 17 slides accordingly, so that adjusting plate 17 drives clamping plate 18 to slide out of groove 4. Then, electric telescopic rod 5 is started to drive fixing block 6 to move towards packaging bag, so that clamping plate 18 positions packaging roller.

[0022] The conveying mechanism includes a tensioning component 19, a conveying component 20, and a conveying shaft 21. The tensioning component 19 is installed on the lower part of one side of the support 2, the conveying component 20 is installed on the upper part of one side of the support 2, and the conveying shaft 21 is installed on one side of the surface of the base 1.

[0023] By setting up the tensioning component 19, the conveying component 20 and the conveying shaft 21, the material can be conveyed in an orderly manner.

[0024] The controller 23 is fixedly connected to the other side of the surface of the bracket 2;

[0033] By setting up the conveyor shaft 21, it works in conjunction with the conveyor assembly 20 to achieve the orderly conveying of materials.

[0034] Working principle and usage process of this utility model:

[0035] By placing the packaging film or thin film material onto the unwinding roller 3, which has a groove 4 on its outer wall for guidance, the motor 7 inside the fixing block 6 is activated. The motor 7 drives the screw 8 to rotate, and the screw 8 drives the threaded sleeve 11 to move. The threaded sleeve 11 drives the fixing frame 13 to move laterally, which in turn drives the connecting plate 15 to move. With the cooperation of the connecting rod 16, the connecting plate 14 connected to the fixing frame 12 can move in linkage. The adjusting plate 17 slides accordingly, causing the adjusting plate 17 to drive the clamping plate 18 to slide out of the groove 4. Then, the electric telescopic rod 5 is activated to drive the fixing block 6 to move towards the packaging bag, so that the clamping plate 18 positions the packaging roller.
