Description

Technical Field

[0001] This utility model belongs to the field of rubber band conveying technology for swimming crab binding machines, specifically relating to a rubber band conveying mechanism for swimming crab binding machines. Background Technology

[0002] The applicant's designed and developed swimming crab binding machine includes rubber band cutting, and the resulting rubber bands need to be spread open by a rubber band spreading mechanism to bind the swimming crabs. However, the applicant's design lacks a rubber band conveying or transmission mechanism, causing the cut rubber bands to not enter the rubber band spreading mechanism in the intended direction during operation. Even with intermediate rubber band fixing or clamping mechanisms, there is a lack of integration between the components, resulting in the equipment not achieving optimal performance. Summary of the Invention

[0003] The purpose of this utility model is to design a rubber band conveying mechanism for a swimming crab binding machine, which smoothly conveys the cut rubber band to the spreading claw of the rubber band spreading mechanism through actions such as fixing, rotating and pushing.

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

[0005] A rubber band conveying mechanism for a swimming crab binding machine includes a support plate, a feeding component, a pushing unit, and a reciprocating mechanism mounted on the support plate. A guide groove is formed on the support plate, and a roller is installed in the guide groove. The movable block of the feeding component is connected to the roller through a slider of the reciprocating mechanism. The reciprocating mechanism causes the slider to move back and forth along the guide groove with the roller, thereby enabling the feeding component to move, rotate, or flip. The pushing unit is used to push the feeding component to push out the rubber band inside the feeding component.

[0006] Furthermore, the feeding assembly includes a frame, an L-shaped movable block is installed at the front end of the frame, an annular groove is provided on the surface, a rubber band is embedded in the annular groove, and a through hole is opened corresponding to the annular groove. A vertical plate is installed at the rear end of the frame, a movable rod is installed on the vertical plate, and the movable rod is connected to a push rod sleeved with a spring. When the movable rod is pressed, the pressure is transmitted to the push rod, and the push rod pushes out or ejects the rubber band inside the annular groove.

[0007] Furthermore, in the reciprocating mechanism, one side of the slider is a movable block, and the other side is a crank. The movable block and the crank are mounted on the slider via a shaft. A roller is installed at the other end of the crank and is placed in a guide groove. The guide groove is designed as an L-shaped guide groove.

[0008] Furthermore, the reciprocating mechanism includes a drive motor, the output shaft of which is connected to a crank arm, one end of which is hinged to a connecting rod, the other end of which is hinged to a slider, a slide bar is installed between the slide blocks, and the slider is mounted on the slide bar.

[0009] Furthermore, the pushing unit includes a rotating joint hinged to the bearing plate, with a connecting rod connected to one end of the rotating joint and an adjustable push plate installed at the other end of the rotating joint.

[0010] Furthermore, the adjustable push plate includes a fixed slide rod mounted on the support plate, a movable slider mounted on the fixed slide rod, an L-shaped push plate mounted in front of the movable slider, and a movable wheel mounted on the back of the movable slider.

[0011] The above technical solution can achieve the following beneficial effects:

[0012] This invention utilizes the L-shaped movable part of the feeding assembly in conjunction with the cutting structure of the rubber band tube to cut the rubber band tube into rubber bands. The cut rubber bands are left in the annular groove. The reciprocating mechanism drives the L-shaped movable part of the feeding assembly to move, flip, or rotate. After the L-shaped movable part carries the rubber band to the appropriate position, the push plate of the upper pushing unit pushes the movable rod and its push rod, thereby pushing or ejecting the rubber band in the annular groove and smoothly placing it onto the opening claw of the opening mechanism.

[0013] The entire structure allows the rubber band to be cut or smoothly inserted into the spreading mechanism. The various components work together to improve the conveying efficiency of the rubber band, and each structure can be adapted to the actual layout. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-12 Further description of this utility model:

[0029] like Figure 1 As shown, a rubber band conveying mechanism for a swimming crab binding machine includes a support plate 1, a feeding assembly 3 mounted on the support plate, a pushing unit 4, and a reciprocating mechanism 2.

[0030] in, Figure 2 , 3 As shown in Figure 4, the feeding assembly 3 includes a frame 31, an L-shaped movable block 32 is installed at the front end of the frame, and an annular groove 33 is provided on the surface. A rubber band is embedded in the annular groove, and a through hole 34 is opened corresponding to the annular groove. A vertical plate is installed at the rear end of the frame, and a movable rod 36 is installed on the vertical plate. The movable rod 36 is connected to a push rod 35 through an end plate 37. A spring 38 is inserted into the push rod 35. When pressure or thrust is applied to the top of the movable rod, the movable rod pushes the push rod 35 to push out or eject the rubber band inside the annular groove.

[0031] Figure 5 , 6 As shown in Figure 7, the pushing unit 4 includes a rotating joint 41 hinged to the support plate 1. The rotating joint is V-shaped, with one end of a connecting rod hinged to the right end of the rotating joint. The other end of the connecting rod is connected to a reciprocating motion structure (not shown in the figure), which only needs to drive the rotating joint to reciprocate; a reciprocating motion structure with special features is not required. A hole is provided on the left end of the rotating joint 41, into which a guide wheel 46 of an adjustable push plate is inserted. The guide wheel is mounted in a limiting groove 45 of the support plate 1. The adjustable push plate includes a fixed slide rod 44 mounted on the support plate, a movable slider 43 mounted on the fixed slide rod 44, an L-shaped push plate 42 mounted on one side of the movable slider 43, and a guide wheel 46 mounted on the other side.

[0032] When the right side of the rotating joint 41 is pulled to the right, under the action of the hinge structure, the left end hole of the rotating joint 41 pulls the guide wheel 46 to move downward along the limiting groove 45, and the L-shaped push plate 42 also moves downward. If the right side of the rotating joint 41 is pushed to the left, under the action of the hinge structure, the left end hole of the rotating joint 41 will pull the guide wheel 46 to move upward along the limiting groove 45, and the L-shaped push plate 42 also moves upward.

[0033] Figure 1 The reciprocating mechanism includes a drive motor 21, the output shaft of which is connected to a crank arm 22. The crank arm is hinged to the right end of a connecting rod 23, and the left end of the connecting rod is hinged to a slider 24. The slider is mounted on two slide rods 25, and the two ends of the slide rods 25 are supported by slide blocks 26. When the motor rotates, the crank arm and the connecting rod drive the slider 24 to reciprocate along the slide rods 25 (sliding back and forth).

[0034] in, Figure 8 As shown, the outer side of the slider contacts the L-shaped movable part, and the inner side contacts the crank 27. Specifically, the L-shaped movable part and one end of the crank 27 are connected by a shaft, and a bearing is provided in the middle of the slider so that the L-shaped movable part and the crank 27 can rotate together. The other end of the crank is hinged to a roller 6, which is located in the L-shaped guide groove 5.

[0035] Figure 1 , 9 As shown in Figure 7, the initial state diagram of the rubber band conveying mechanism is displayed, that is, the feeding component 3 is in a horizontal state, and the slider of the reciprocating mechanism is located at the far left of the slide bar. At this time, the side of the L-shaped movable part with the annular groove 33 is close to the rubber band tube cutting structure. The rubber band tube on the left is inserted into the annular groove 33 along the conveying mechanism. When the cutting of the rubber band tube cutting structure cuts down from the top, the rubber band can be cut out smoothly. At this time, the rubber band is embedded in the annular groove of the L-shaped movable part. Subsequently, the drive motor of the reciprocating mechanism rotates, and the connecting rod pulls the slider to move to the right. At the same time, under the action of the L-shaped guide groove, the slider and its feeding component first move horizontally to the right. When the roller reaches the angle of the L-shaped guide groove, the feeding component rotates counterclockwise. Figure 10 As shown), the drive motor continues to rotate, and the rollers of the feeding assembly gradually reach the highest point of the L-shaped guide groove (as shown). Figure 12 (As shown in the roller state), the movable rod of the feeding assembly is located below the pushing unit 4. At the same time, the L-shaped push plate of the pushing unit 4 moves downward under the pull of the rotating joint, pushing or pressing the movable rod downward, and then pressing and pushing the movable rod downward. The movable rod transmits pressure to the push rod, and the push rod moves downward along the through hole, pushing out the rubber band in the annular groove. Figure 11 (As shown).

[0036] It should be noted that in practical applications, the opening claw of the opening mechanism is installed at the position where the rubber band is extended. After the rubber band is extended, it falls smoothly into the opening claw.

[0037] The above descriptions are all preferred embodiments of this utility model. For those skilled in the art, any modifications to this utility model in various equivalent forms without departing from the principle of this utility model shall fall within the protection scope of the appended claims.
