[0004] The existing technical solution described above has the following drawbacks: by driving multiple second electric push rods to adjust the distance between the fan and the yarn, it is inconvenient to adjust the distance between the fan and the yarn in each direction at the same time, which affects the efficiency of blowing off the lint and impurities on the yarn, thereby reducing the quality and color uniformity of the fabric processed from the yarn, and affecting the quality of single-sided sweatshirt knitting. Utility Model Content

[0005] The purpose of this invention is to provide a circular knitting machine for single-sided sweatshirts, which solves the problem that existing circular knitting machines for single-sided sweatshirts cannot conveniently adjust the distance between the fan and the yarn in each direction at the same time.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a circular knitting machine for single-sided sweatshirts, including a sleeve;

[0007] An adjustment mechanism is installed on the outer wall of the sleeve;

[0008] The adjusting mechanism includes a first motor fixedly installed on the top of the sleeve. The output shaft of the first motor is fixedly connected to a threaded rod via a coupling. A conical movable block is movably connected to the outer wall of the threaded rod. A support column is movably connected to the outer wall of the conical movable block. A baffle is fixedly connected to the outer wall of the support column. A fan is fixedly connected to the outer wall of the support column.

[0009] Preferably, the conical movable block has a threaded groove inside, a guide rod is fixedly connected to the top of the conical movable block, and a return spring is fixedly connected to one side of the baffle.

[0010] Preferably, the threaded rod and the sleeve form a rotating structure, and the threaded rod is threadedly connected to the conical movable block through a threaded groove, so that the threaded rod can rotate to drive the conical movable block to move and rise.

[0011] Preferably, the guide rod and the sleeve form a sliding structure, and the conical movable block and the support column form a sliding structure, which allows the conical movable block to move down and squeeze the support column.

[0012] Preferably, the return spring is sleeved on the outer wall of the support column, the support column and the sleeve form a sliding structure, the support column is arranged in a ring around the central axis of the conical movable block, and the guide rod is symmetrically arranged around the central axis of the conical movable block, so that the support column can slide and adjust along the sleeve.

[0013] Preferably, a lifting mechanism is fixedly connected to the bottom of the sleeve. The lifting mechanism includes a lifting column fixedly installed at the bottom of the sleeve. A rack is fixedly connected to the outer wall of the lifting column. A housing is movably connected to the outer wall of the lifting column. A storage groove is provided inside the housing. A second motor is fixedly connected to the outer wall of the housing. The output shaft of the second motor is fixedly connected to a rotating rod through a coupling. A gear is fixedly connected to the outer wall of the rotating rod.

[0014] Preferably, the gear meshes with the rack, and the lifting column forms a sliding structure with the housing through the receiving groove, which allows the gear to rotate and drive the lifting column to rise and fall.

[0015] The advantages of the single-sided sweatshirt knitting circular knitting machine provided by this utility model are as follows:

[0016] By using the sleeve, adjustment mechanism and fan, the first motor can be started to rotate the threaded rod, which will cause the conical surface of the conical moving block to press against the support column, causing the support column to slide along the sleeve. This will cause the fans fixedly connected to the outer walls of the three support columns to extend outwards for adjustment, which will facilitate the adjustment of the distance between the fan and the knitting circular knitting machine, and can more thoroughly blow off the lint and impurities on the yarn.

[0017] Furthermore, under the action of the guide rod, the stability of the conical moving block lifting and lowering can be improved, and the stability of the fan adjustment can be further improved, so that the lint and impurities on the yarn are blown off, improving the quality and color uniformity of the fabric processed from the yarn, and improving the quality of single-sided sweatshirt knitting.

[0018] Furthermore, with the combined action of the return spring and the baffle, the conical movable block can be raised while the support column is adjusted inward, thereby increasing the adjustment range.

[0019] By setting up a fan and lifting mechanism, and by starting the second motor, the gear fixedly connected to the outer wall of the rotating rod can be rotated, which can move the rack and drive the lifting column to rise and fall, so as to facilitate the height adjustment of the fan and increase the range of the fan that blows off the lint and impurities from the yarn.

[0020] Furthermore, the combined effect of the lifting column and the storage slot can improve the stability of the fan's lifting and lowering. Attached Figure Description

The guide rod 25 is symmetrically arranged around the central axis of the conical movable block 23.

[0030] By starting the first motor 21, the threaded rod 22 can be rotated. Since the threaded rod 22 is threadedly connected to the conical movable block 23 through the threaded groove 24, the conical movable block 23 can be moved, causing the guide rod 25 to slide along the sleeve 1. This causes the conical surface of the conical movable block 23 to press against the support column 26, causing the support column 26 to slide along the sleeve 1. This causes the baffle 27 to press against the return spring 28, causing the fans 3, which are fixedly connected to the outer walls of the three support columns 26, to extend outwards simultaneously for adjustment. This allows the distance between the fans 3 and the knitting circular knitting machine to be adjusted. Starting the fans 3 can blow off the lint and impurities on the yarn.

[0031] Reference Figure 2 and Figure 5 As shown, a lifting mechanism 4 is fixedly connected to the bottom of the sleeve 1.
