But when sewing, after the cutting pieces are stacked and sewn, the sewing line and the edge of the cutting piece sewn are located in the outside of the pillowcase, so the pillowcase needs to be turned inside out at the opening of the pillowcase before delivery.

[0003] At present, the turning step of the pillowcase mainly depends on manual operation: a common way is that the worker turns the pillowcase inside out by fingertips, or further with the help of auxiliary tools, the common pillowcase turning auxiliary tools at present, such as the pillowcase turning device for textile provided by the patent document CN208414926U, the auxiliary tools generally have two sharp ends, the cloth at both ends of the opening of the pillowcase is hung on the two sharp ends, then the worker pulls the pillowcase downward at the opening, and the pillowcase is turned inside out while being sleeved on the tool.

[0004] In the above process, although the tool is used to assist, the efficiency of turning the pillowcase is improved and the operation difficulty is reduced, but the opening of the pillowcase is generally arranged at the short side of the pillowcase, and the worker needs to sleeve the pillowcase on the auxiliary tool along the long side direction, so it can be seen that in the process, the worker needs to move the opening position of the pillowcase along the complete length of the long side of the pillowcase, then the pillowcase is taken off from the tool, the worker needs to bend or swing arms repeatedly in a large range, so the labor intensity is still large. UTILITY MODEL CONTENTS

[0005] The utility model provides a more convenient and labor-saving pillowcase turning auxiliary equipment aiming at the problem that the current auxiliary turning device still needs the worker to bend and swing arms greatly and the labor intensity is large when turning the pillowcase at present.

[0006] To solve the above problems, the utility model adopts the technical scheme, a pillowcase turning over auxiliary equipment, including frame, be equipped with lifting device on the frame, lifting device and a control device electricity is connected, the lifting end of lifting device is connected with lifting seat, install first dialing lever and second dialing lever on the lifting seat, first dialing lever and / or second dialing lever are hinged with lifting seat and can rotate in vertical plane, be equipped with elastic tensioning piece between the lower end of first dialing lever and the lower end of second dialing lever, the elastic tensioning piece makes first dialing lever second dialing lever become included angle and included angle opening vertical upward.
