AI Technical Summary
The paddle structure design of the existing swimming crab binding machine is unreasonable, resulting in poor coordination with the rubber band expansion mechanism, poor paddle synchronization effect, and low friction when plucking, which easily leads to plucking failure.
The paddle mechanism is designed using a gear set. The driving wheel, driven wheel and gear meshing drive the rotating rod to rotate. A groove is designed at the end of the paddle. The surface of the groove is rough and is used to hook the rubber band, so that the two sets of paddles can rotate synchronously to plucking the rubber band.
The effective cooperation between the pick and the rubber band is achieved to avoid slipping and ensure that the rubber band is successfully plucked. The structure is simple and reliable.

Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of swimming crab binding machines, and particularly relates to a paddle mechanism of a swimming crab binding machine. Background Art
[0002] The applicant previously applied for swimming crab binding machine technology, patent publication number CN116788568A. This technology installs a pair of paddles on the inside of the window. When the rubber band stretching part leaves the window, the paddles block the rubber band, causing the rubber band to slide down from the rubber band stretching part to bind the large claws of the swimming crab. However, the structural design of this part of the paddles is not reasonable, and the coordination between the paddles and other mechanical parts is not high, and the paddle synchronization effect is poor. Secondly, when the rubber band is moved, the contact friction between the paddles and the rubber band is small, and there is a possibility of paddle failure. Summary of the Invention
[0003] The purpose of the present invention is to design a paddle mechanism of a swimming crab binding machine, which can fully cooperate with the rubber band stretching mechanism to effectively and successfully paddle the rubber band at the window.
[0004] In order to achieve the above object, the technical solution adopted by the present invention is as follows:
[0005] The paddle mechanism of the swimming crab binding machine includes a swimming crab binding machine body, a plurality of rubber band stretching mechanisms are arranged on the turntable of the swimming crab binding machine body, a window is arranged on the casing of the swimming crab binding machine, and the paddle mechanism is installed on the casing. The paddle mechanism includes a driving part, the output shaft of the driving part is installed with a driving wheel, the driving wheel is engaged with the right driven wheel, the right side of the right driven wheel is engaged with the first gear, the left side of the right driven wheel is engaged with the left driven wheel, and the left driven wheel is engaged with the second gear. The first gear and the second gear drive the rotating rod to rotate, and a paddle is installed at the bottom of the rotating rod, and a groove is opened at the end of the paddle.
[0006] Furthermore, two picks are placed on both sides of the window, and when rotated, the grooves of the picks just hook the rubber band.
[0007] Furthermore, the groove is in a V-shape, an arc shape or a square groove shape.
[0008] Furthermore, the surface of the groove is designed to be a rough surface.
[0009] Furthermore, the rotating rod is installed on the inner side of the casing through a plurality of bearing seats.
[0010] The following beneficial effects can be achieved through the above technical solution:
[0011] The utility model completely overcomes the problem that the pick slips when the rubber band is pulled off, and the pick cannot be successfully pulled off. The utility model adopts a gear set to realize the simultaneous opposite rotation of two groups of picks, and the rubber band is pulled off when they rotate inward at the same time. After being pulled off, they are rotated outward at the same time to return to the original position and prepare for subsequent work.
[0012] The utility model has a simple overall structure, and the pick is designed with a groove with a rough surface, which can effectively hook the rubber band, thus preventing the rubber band from slipping. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below with reference to the accompanying drawings:
[0020] Figure 1-4 As shown, this embodiment provides a paddle mechanism for a swimming crab binding machine. Figure 4 As shown, it includes a swimming crab binding machine body, a plurality of rubber band stretching mechanisms are set on the turntable of the swimming crab binding machine body, a window is set on the casing of the swimming crab binding machine, and a paddle mechanism is installed on the casing 1 ( Figure 1 As shown), the paddle mechanism includes a driving part 7, which is specifically a motor. The output shaft of the driving part 7 is installed with a driving wheel 2, and the driving wheel 2 is engaged with the right driven wheel 3. The right side of the right driven wheel 3 is engaged with the first gear 4, and the left side of the right driven wheel 3 is engaged with the left driven wheel 5. The left driven wheel 5 is engaged with the second gear 6 ( Figure 3 As shown), the first gear 4 and the second gear 6 drive the rotating rod 8 to rotate, and a paddle 10 is installed at the bottom of the rotating rod, and a groove 11 is opened at the end of the paddle 10 ( Figure 2 (As shown). Two paddles 10 are placed on either side of the window. When rotated, the paddles' grooves 11 precisely hook onto the rubber band. These grooves 11 are V-shaped, arc-shaped, or square-shaped. The surface of grooves 11 is designed to be rough. The rotating rod 8 is mounted on the inside of the housing via several bearing blocks 9.
[0021] The utility model installs a paddle mechanism on the casing of the swimming crab binding machine, and the two groups of paddles are respectively located on the left and right sides of the window. The top of the rotating rod vertically connected to the right paddle is covered with a first gear 4, and the top of the rotating rod vertically connected to the left paddle is covered with a second gear 6. The motor is installed on the top of the casing, and its output shaft is connected to the driving wheel 2, the driving wheel 2 is engaged with the right driven wheel 3, the right side of the right driven wheel 3 is engaged with the first gear 4, the left side of the right driven wheel 3 is engaged with the left driven wheel 5, and the left driven wheel 5 is engaged with the second gear 6. Figure 4 As shown, after the rubber band expansion mechanism expands the rubber band, the swimming crab is placed in the rubber band area, and the paddles on both sides rotate inward at the same time. After the grooves of the paddles contact the rubber band, the rubber band is pulled off the rubber band expansion mechanism, and the rubber band is fastened to the swimming crab. Then, the paddles on both sides rotate outward at the same time to return to their original positions, ready for the next time to expand the rubber band.
