[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , an embodiment provided by the present invention:

[0023] A roller structure of an assemblable food packaging machine: including a support frame 1, a motor 2 is fixedly connected to the surface of the support frame 1, a limit disc 3 is fixedly connected to the output shaft of the motor 2, a roller shaft 4 is fixedly connected to the surface of the limit disc 3, a roller sleeve 5 is sleeved on the surface of the roller shaft 4, a first bolt 6 is threadedly connected to the surface of the roller shaft 4, an extension shaft 7 is fixedly connected to the surface of the first bolt 6, a second bolt 8 is threadedly connected to the surface of the extension shaft 7, a limit cylinder 9 is fixedly connected to the surface of the second bolt 8, a knob 10 is fixedly connected to the surface of the limit cylinder 9, a drive rod 11 is perforatedly connected to the surface of the knob 10, the motor 2 drives the limit disc 3 to rotate through the output shaft, and the limit disc 3 drives the roller shaft 4 and the roller sleeve 5 to rotate, so as to realize the transmission of the packaging bag. The roller of this packaging machine divides the roller into a roller shaft 4 and a roller sleeve 5. During use, the roller sleeve 5 can be assembled onto the roller shaft 4 for use. At the same time, the roller sleeve 5 is in direct contact with the packaging bag. By disassembling the roller sleeve 5 from the roller shaft 4, cleaning and disinfection can be carried out, which is convenient for maintaining the roller, making the maintenance work time-saving and labor-saving. At the same time, by installing an extension shaft 7 on the roller shaft 4, roller sleeves 5 of different lengths can be adapted, and thus packaging bags of different widths can be adapted.

[0024] Furthermore, multiple groups of limit rods are arranged on the surface of the roller shaft 4, and the multiple groups of limit rods are evenly distributed in a circular shape. Guide holes are opened on the surface of the roller sleeve 5, and the cross-sectional shape of the guide hole of the roller sleeve 5 is the same as the cross-sectional shape of the roller shaft 4. During the rotation of the roller shaft 4, the roller shaft 4 will drive the roller sleeve 5 to rotate through the limit rods, so as to realize the transmission of the packaging bag.

[0025] Further, multiple groups of limiting rods are arranged on the surface of the extension shaft 7, and the multiple groups of limiting rods are evenly distributed in a circular shape. The cross-section of the extension shaft 7 is the same as that of the roller shaft 4. The roller sleeve 5 is sleeved on the surfaces of both the roller shaft 4 and the extension shaft 7 through the guiding holes. The extension shaft 7 extends the length of the roller shaft 4, thus facilitating the assembly of roller sleeves 5 with different lengths on the roller shaft 4.

[0026] Further, a threaded groove is provided at one end of the roller shaft 4. The first bolt 6 is threadedly connected to the threaded groove of the roller shaft 4. The extension shaft 7 is in contact connection with one end of the roller shaft 4. The extension shaft 7 is installed on the surface of the roller shaft 4 through the first bolt 6, and the extension shaft 7 and the roller shaft 4 overlap with each other, ensuring that the limiting rods of the roller shaft 4 and the limiting rods of the extension shaft 7 are on the same straight line, so that the roller sleeve 5 can be sleeved on both the roller shaft 4 and the extension shaft 7 simultaneously.

[0027] Further, a threaded groove is provided at one end of the extension shaft 7 away from the first bolt 6. Another extension shaft 7 can be additionally installed on the extension shaft 7 to increase the length of the roller shaft 4. Circular holes are provided on the surface of the extension shaft 7. The driving rod 11 can pass through the circular holes of the extension shaft 7, so as to rotate the first bolt 6 through the extension shaft 7. The second bolt 8 is threadedly connected to the circular groove of the extension shaft 7, and the second bolt 8 installs the limiting cylinder 9 on the surface of the roller sleeve 5.

[0028] Further, the diameter of the limiting disc 3 is the same as that of the limiting cylinder 9. The diameter of the limiting cylinder 9 is larger than the diameter of the roller shaft 4 and smaller than the diameter of the roller sleeve 5. The diameter of the limiting disc 3 is larger than the diameter of the roller shaft 4 and smaller than the diameter of the roller sleeve 5. One end of the roller sleeve 5 is in contact connection with the limiting disc 3, and the other end of the roller sleeve 5 is in contact connection with the limiting cylinder 9. And there is no contact between the limiting cylinder 9 and the extension shaft 7. The limiting disc 3 and the limiting cylinder 9 limit the roller sleeve 5 on the surface of the roller shaft 4, thus completing the assembly between the roller shaft 4 and the roller sleeve 5.

[0029] Further, the rotation direction of the roller shaft 4 is the same as the installation and rotation direction of the first bolt 6 in the threaded groove of the roller shaft 4. The rotation direction of the extension shaft 7 is the same as the installation and rotation direction of the second bolt 8 in the threaded groove of the extension shaft 7. The rotation directions of the roller shaft 4 and the extension shaft 7 are also the same, so that during the rotation of the roller shaft 4 and the extension shaft 7, the first bolt 6 and the second bolt 8 will not loosen and fall off. Circular holes are provided on the surface of the knob 10. The driving rod 11 passes through the circular holes of the knob 10, and the rotation of the knob 10 can be controlled through the driving rod 11, thereby controlling the rotation of the second bolt 8 in the threaded groove of the extension shaft 7. When not in use, the driving rod 11 can be pulled out from the circular hole of the support frame 1.

[0030] Working principle: Rotate the first bolt 6 on the threaded groove of the roller shaft 4, so as to install the extension shaft 7 on the surface of the roller shaft 4, and make the cross-section of the extension shaft 7 coincide with the cross-section of the roller shaft 4. Sleeve the roller sleeve body 5 on both the roller shaft 4 and the extension shaft 7 at the same time, and make one end of the roller sleeve body 5 contact and connect to the limit disc 3. Drive the second bolt 8 to rotate on the surface of the extension shaft 7 through the knob 10, so that the limit cylinder 9 contacts and connects to the end of the roller sleeve body 5 far from the limit disc 3. At this time, the limit cylinder 9 cooperates with the limit disc 3 to assemble the roller sleeve body 5 on the roller shaft 4. When the roller sleeve body 5 is disassembled, penetrate the driving rod 11 through the circular hole of the knob 10, drive the knob 10 to rotate through the driving rod 11, and then drive the second bolt 8 to rotate on the threaded groove of the extension shaft 7, cancel the restriction of the limit cylinder 9 on the roller sleeve body 5, and facilitate the removal of the roller sleeve body 5 from the roller shaft 4 for cleaning and disinfection, so as to facilitate the maintenance of the roller and make the maintenance work time-saving and labor-saving.
