[0002] In daily life, inflatable bag filling and packaging technology is widely used in the transportation industry. It plays a role of buffering and shock absorption for small goods and valuable goods, such as mobile phones and computers, and can effectively protect small goods from possible damage during transportation. The inflatable filling packaging machine inflates the rolled materials into gas-filled bags. The rollers that convey the materials and heat and seal them are prone to adhere to plastic and cause pollution, affecting the sealing effect of the inflatable bags. Therefore, it is necessary to regularly clean the dirt on the surface of the rollers and replace the heating wires. Maintenance work such as. The rollers used in traditional packaging machines are directly fixed to the main shaft of the inflatable packaging machine body through a threaded connection, which is very inconvenient to maintain, affecting the maintainability and production efficiency of the inflatable filling packaging machine. Summary of the invention

[0003] The purpose of the present invention is to provide a roller for an inflatable filling packaging machine which can be easily disassembled and improves the maintainability and production efficiency of the equipment, in view of the shortcomings of the previous traditional technology and the inconvenience of using the roller of the inflatable packaging machine produced.

The side of the end cover is provided with a wire groove for accommodating a heating wire. The end surface of the end cover is provided with two arc grooves for accommodating a heating wire tensioning spring. The lower end of a screw at the inner end of each arc groove passes through the end cover and is connected to a conductive column through a thread. Two through holes corresponding to the positions of the conductive columns are opened on the base. The conductive columns pass through the two through holes of the base respectively. A threaded hole is provided at the center of the base and can be connected to the main shaft of the packaging machine through a thread.

The top of the quick-release shaft is made into a button shape, and two grooves are opened on both sides of the quick-release shaft. The grooves have inclined surfaces, and corresponding positions of the inner hole of the packaging machine main shaft are respectively provided with card slots. When the button in the quick-release mechanism is released, the steel ball is pushed out by the inclined surface of the groove and stuck in the card slot of the main shaft. The base, the end cover and the packaging machine main shaft are fixed together at this time. When the button is squeezed and pulled outward, the steel balls can be pressed into the two grooves respectively, thereby separating the end cover from the base.

DETAILED DESCRIPTION

[0017] Reference Figures 1 to 5The present invention provides a roller for an inflatable filling packaging machine, comprising a base 2 and an end cover 1. The side of the end cover 1 is provided with a wire groove 12 for accommodating a heating wire. The end face of the end cover 1 is provided with two arc grooves 17 for accommodating a heating wire tensioning spring 19. The two arc grooves 17 on the end face of the end cover 1 are designed symmetrically with respect to the center of the roller, which can reduce the vibration generated during the operation of the roller. The lower end of the screw 18 at the inner end of each arc groove 17 passes through the end cover 1 and is connected to the conductive column 4 through a thread. The upper end of the screw 18 on the end cover 1 compresses one end of the tensioning spring 19, and the other end of the tensioning spring 19 is connected to the heating wire. The base 2 is provided with two through holes corresponding to the positions of the conductive column 4. The conductive column 4 passes through the two through holes of the base 2 respectively. The center position of the base 1 is provided with a threaded hole that can be connected to the main shaft 7 of the packaging machine through a thread. A quick-release mechanism for closing and opening the base 2 and the end cover 1 is provided. In the quick-release mechanism, the lower end of the quick-release shaft 14 extends into the main shaft. In the inner hole, the lower end of the annular spring 8 is tightly against the countersunk hole 22, and the upper end is tightly against the quick-release shaft 14. A quick-release button 15 is provided at the upper end of the quick-release shaft 14 and extends out of the positioning pressure cover 16. The positioning pressure cover 16 is fixed on the end cover 1. Two grooves 9 are provided on both sides of the quick-release shaft 14. Each groove 9 has an inclined surface 20 at the lower part. Card grooves 10 are respectively provided in the inner hole of the main shaft corresponding to the positions of the two grooves 9. The steel ball 6 is stuck in the card groove 10. The button 15 in the quick-release mechanism is squeezed and pulled outward, so that the steel ball 6 can be pressed into the two grooves 9 respectively, thereby separating the end cover 1 from the base 2.

[0018] The through hole of the base 2 is provided with a metal sleeve 3 for connecting the end cover 1 and the output of the packaging machine slip ring, and one end of the metal sleeve 3 is connected to the output wire 21 of the slip ring rotor on the machine body; there is a compression spring sheet 11 on the conductive column 4, and the compression spring sheet 11 is in contact with the metal sleeve 3 on the base 2 to ensure reliable contact between the conductive column 4 and the metal sleeve 3 and stable power supply to the heating wire; the quick-release mechanism is located under the end cover 1 and is equipped with a first retaining ring 13, which fixes the quick-release shaft 14 on the end cover 2 with the umbrella-shaped end face of the quick-release shaft 5; the main shaft 7 of the packaging machine is located under the base 2 and is equipped with a second retaining ring 5 to ensure positioning in the axial direction.

[0019] When the present invention is installed, the base 1 is connected to the main shaft 7 of the packaging machine body through threads, the lower end of the annular spring 8 is tightly pressed against the countersunk hole, and the upper end is tightly pressed against the quick-release shaft 14. The quick-release shaft 14 pushes out the steel ball 6 through the internal groove 9 and its inclined surface 20, and the steel ball 6 is exposed and stuck in the corresponding groove 10 on the main shaft 7 of the packaging machine body. The conductive column 4 is inserted into the inner hole of the metal sleeve 3 on the base 2. The metal sleeve 3 and the through hole in the base 2 are interference connected. The metal sleeve 3 is connected to the output wire 21 of the slip ring rotor on the body by welding. The two conductive columns 4 adopt the same design, so as to ensure that they can draw electricity from the packaging machine body. When the present invention needs to be disassembled, by squeezing downward and pulling the end cover 1 outward, the steel ball 6 is pressed into the grooves 9 on both sides, and the quick-release mechanism and the conductive column 4 can be pulled out from the base 2, so that the end cover 1 and all parts connected thereto can be separated from the base 2.
