DETAILED DESCRIPTION

[0015] The present invention is further described and understood by the following non-limiting examples.

[0016] like Figure 1-3 As shown, the present invention is a glove machine drum transmission mechanism, comprising a bottom plate 1, two groups of drum assemblies 2 symmetrically arranged on the bottom plate 1, the drum assembly 2 comprising a drum 22 and a drum gear 23 arranged on the same drum shaft 21, the drum groove of the drum 22 and the tooth groove 231 on the drum gear 23 correspond one to one; the drum shaft 21 ensures that the rotation direction and rotation pace of the drum 22 and the drum gear 23 are consistent.

[0017] Two mutually parallel positioning cylinders 3 are symmetrically provided on the base plate 1. The two positioning cylinders 3 correspond to the two roller gears 23 one by one. The cylinder axis of the positioning cylinder 3 is the slope axis 31, and the slope axis 31 is vertically inserted into the tooth groove 231 of the corresponding roller gear 23; thereby controlling the positioning and locking of the roller gear 23.

[0018] The bottom plate 1 is also fixedly provided with a push cylinder 4 and a pressure block 5 which are coaxial with the symmetry axis of the two groups of roller assemblies 2. A through cavity is provided in the pressure block 5, and a slider 6 is provided in the cavity. The cylinder shaft end of the push cylinder 4 is provided in the cavity of the pressure block 5 and is fixedly connected with one end of the slider 6. The other end of the slider 6 protrudes from the pressure block 5. The cylinder shaft of the push cylinder 4 controls the slider 6 to reciprocate in the pressure block 5.

[0019] One end of the slider 6 protruding from the pressure block 5 is inclined inwardly along the central axis and is provided with a left inclined end face 61 and a right inclined end face 62. A left swing block 7 and a right swing block 8 are symmetrically provided along the center line on the bottom plate 1. When the cylinder shaft of the push cylinder 4 controls the slider 6 to be at the maximum stroke, one end of the left swing block 7 is arranged close to the left inclined end face 61, and one end of the right swing block 8 is arranged close to the right inclined end face 62. The left swing block 7 and the right swing block 8 are respectively fixed to the bottom plate 1 by a pin 9 near one end and can rotate around the pin 9. The other ends of the left swing block 7 and the right swing block 8 are respectively inserted into the tooth grooves 231 of the roller gear 23 on both sides.

[0020] The end of the left swing block 7 close to the pin shaft 9 is connected to the slider 6 through a tension spring 10, and the end of the right swing block 8 close to the pin shaft 9 is connected to the slider 6 through a tension spring 10; corresponding positions on the left swing block 7, the right swing block 8 and the slider 6 are all provided with fixing columns 11 for fixing the tension spring 10, and the two ends of the tension spring 10 are respectively arranged on the corresponding fixing columns 11.

[0021] When in use, the two positioning cylinders 3 are set to move in unison, and the push cylinder 4 is set to have a stroke opposite to that of the positioning cylinder 3. When the air intake bevel shafts 31 of the two positioning cylinders 3 are retracted to release the two roller gears 23, the air intake of the push cylinder 4 pushes the slider 6 to move along the pressure block 5 toward the pin shaft 9, thereby pushing the left swing block 7 and the right swing block 8 to move upward respectively, and the top ends of the left swing block 7 and the right swing block 8 are inserted into the tooth grooves 231 of the roller gear 23; the two roller gears 23 rotate upward by one tooth under the push of the left swing block 7 and the right swing block 8, that is, the left roller gear 23 rotates one tooth counterclockwise, and the right roller gear 23 rotates one tooth clockwise. At this time, the two positioning cylinders 3 are reset, and the bevel shafts 31 are sent out and lock the corresponding roller gears 23.

[0022] The push cylinder 4 is reset, and the slider 6 moves along the pressure block 5 toward the push cylinder 4. Under the action of the tooth groove 231 of the roller gear 23 and the tension spring 10, the top ends of the left swing block 7 and the right swing block 8 rotate upward along the pin shaft 9. After the left swing block 7 and the right swing block 8 pass over a tooth, they are inserted into the next tooth groove 231 and enter the next cycle.

[0023] Since the roller 22 is coaxial with the roller gear 23, and the roller groove corresponds to the groove of the roller gear 23 one by one, driven by the roller gear 23, the two rollers 22 rotate clockwise and counterclockwise respectively to meet the weaving requirements.
