Description

Technical Field

[0001] The utility model relates to the technical field of a cloth rolling machine gearbox, in particular to a digital chassis assembly which is convenient for maintenance and installation. Background Art

[0002] Circular knitting machines are basic equipment in the textile industry, also known as large circular machines. They use multiple knitting needles set on the needle plate and needle cylinder to weave yarns of the same or different materials into circular fabrics. After the circular knitting machine completes weaving, the fabric needs to be pulled and rolled into a roll or folded into a pile for easy storage and transportation. In order to keep the rolled or folded fabric flat without creases, and to make the tension of the fabric even when it is rolled and unfolded. The device that rolls the woven fabric into a bundle of flat fabric rolls is the cloth roll machine set under the circular knitting machine. After the knitting machine weaves the fabric, it needs to be sent to the cloth roll machine, and the cloth pull roller transmission device set on the top of the side case of the cloth roll machine is used to press and flatten the fabric, and cooperate with the cloth roll machine to fold or roll the fabric into the preset specifications.

[0012] A further improvement is that: the fixing device is: the first sealing shell and the second sealing shell are locked on the control box by bolts.

[0013] By adopting the above technical solution, the beneficial effects of the utility model are:

[0014] The structure is simple, space-saving, and convenient for maintenance and installation. When in use, the first sealing shell and the second sealing shell seal the PLC controller and other components to avoid dust pollution and increase service life. When maintenance is required, just remove the screws and then pull out the first sealing shell and the second sealing shell from both sides, and the staff can repair and replace the PLC controller, which greatly facilitates the staff's operation. Moreover, it is placed between the transmission box and the cloth winding machine, which reasonably utilizes the space between the cloth winding machine and the transmission box, saves the space occupied by the installation of the PLC, and is conducive to the operation and installation of the cloth winding machine.
