[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] An auxiliary trolley for disassembling and assembling a spiked roller includes a frame. Multiple first omnidirectional wheels are mounted on the bottom of the frame. Two guide rails are horizontally mounted on the bottom of the frame. A slider is installed inside each guide rail. An extension arm parallel to the guide rail is fixed to one side of the slider. A second omnidirectional wheel is mounted on the side of the extension arm away from the slider. The bottoms of the first and second omnidirectional wheels are flush. A lifting device is mounted on the top of the extension arm near the second omnidirectional wheel. A support base is connected to the lifting end of the lifting device. A receiving groove for accommodating the spiked roller shaft head is formed on the top of the support base.

[0006] Furthermore, the lifting device includes a sleeve, a screw, and a tube. The sleeve is longitudinally fixed to the top of the extension arm. The inside of the sleeve is threaded. The screw is threaded into the sleeve. A round shaft is coaxially connected to the top of the screw. The tube is sleeved on the round shaft. The support is fixed to the top of the tube.

[0007] Furthermore, a crank is connected to the circular shaft.

[0008] Furthermore, the frame includes a support plate, two longitudinal arms, and a handlebar. The guide rail is horizontally mounted on the bottom of the support plate, the first omnidirectional wheel is mounted on the bottom of the support plate, the two longitudinal arms are spaced apart on the top of the support plate, and the handlebar is horizontally fixed between the two handlebars. An ear plate is connected to the outer circumference of the sleeve near the support plate, and a pin is movably inserted into the ear plate. A pin hole is opened on the side of the support plate near the sleeve corresponding to the ear plate, and the pin can pass through the ear plate and be inserted into the pin hole.

[0009] Furthermore, the guide rail is a square tube closed at one end, the slider is slidably connected in the square tube, and a sliding hole matching the shape of the extension arm is opened on the closed end of the square tube, and the extension arm passes through the sliding hole.

[0010] The beneficial effects of this utility model are as follows: When disassembling the licker-in roller, push the frame to the back of the carding machine, then one person holds the frame while two other people pull the two extension arms downwards towards the licker-in roller, so that the support seat receiving groove is aligned with the shaft end of the licker-in roller. Then adjust the lifting device to move the support seat upwards to lift the licker-in roller, and then push the extension arms towards the frame to complete the disassembly of the licker-in roller. The entire operation does not require manual lifting of the licker-in roller onto the trolley, effectively reducing the burden on the operators and avoiding safety hazards. The same principle applies when installing the licker-in roller. Attached Figure Description
