Description

Technical Field

[0001] This utility model relates to a perforated plate transmission mechanism in the field of fishing net machine technology. Background Technology

[0002] Fishing net machines weave fishing nets using the coordinated action of upper and lower hooks. The warp threads of the net are fed to these hooks via perforated angle iron plates. In existing technologies (such as...) Figure 2 The perforated plate angle iron has holes for threading warp threads. A cam on the perforated plate pushes a shank bearing, causing the perforated plate swing arm to swing back and forth. This, in turn, drives a linkage mechanism to swing the perforated plate angle iron's swing arm left and right, which in turn causes the perforated plate angle iron to move left and right, allowing the warp threads to be threaded onto the upper and lower hooks. However, this linkage structure involves many components, making installation and disassembly inconvenient during production and maintenance, and also leading to insufficient transmission accuracy. Utility Model Content

[0003] The purpose of this invention is to provide a perforated plate transmission mechanism for a fishing net machine, which reduces transmission components, makes installation and disassembly more convenient, and effectively improves transmission accuracy.

[0004] To achieve the above objectives, this utility model provides a perforated plate transmission mechanism for a fishing net machine, including a perforated plate angle iron, characterized in that: the perforated plate angle iron is connected to a swing structure, and the swing structure is connected to a transmission structure.

[0005] Compared with the prior art, the beneficial effects of this utility model are that the transmission structure drives the swing structure to swing back and forth, thereby driving the perforated plate angle iron to swing back and forth. The end of the perforated plate angle iron has a hole, and the warp thread is inserted through the hole. The perforated plate angle iron swings back and forth, thereby loading the warp thread onto the upper hook and lower hook respectively in the back and forth motion, realizing the weaving of the fishing net. In addition, the transmission components in the entire swing structure are effectively reduced, making installation and disassembly more convenient, and also effectively improving the transmission accuracy.

[0006] As a further improvement of this utility model, the swing structure includes a connecting rod. The front end of the connecting rod is connected to the angle iron of the perforated plate through a front joint bearing, and the rear end of the connecting rod is connected to the front end of the swing arm through a rear joint bearing. The middle part of the swing arm is hinged to the support plate, the support plate is set on the frame, and the rear end of the swing arm is provided with a shank bearing. The shank bearing cooperates with the transmission structure. The front end of the swing arm is connected to one end of a return spring, and the other end of the return spring is connected to a fixed block set on the frame.

[0007] In this way, the swing arm, through the transmission structure and the return spring, swings back and forth around the middle of the swing arm, thereby driving the connecting rod to move left and right, causing the angle iron of the perforated plate to move left and right, thus enabling the upper and lower hooks to hook the warp threads.

[0008] As a further improvement of this utility model, the transmission structure includes a perforated plate cam that cooperates with a shank bearing. The perforated plate cam is sleeved on the driven shaft, and a perforated plate gear is also sleeved on the driven shaft. The perforated plate gear meshes with the main gear, and the main gear is sleeved on the main shaft.

[0009] In this way, the main shaft is connected to the motor of the fishing net machine. Driven by the motor, it rotates, causing the main gear to rotate, which in turn drives the perforated plate gear to rotate. This drives the perforated plate cam to rotate. The protruding part of the perforated plate cam contacts the shank bearing, causing the swing arm to rotate clockwise around the hinge. When the protruding part of the perforated plate cam disengages from the shank bearing as it rotates, the swing arm rotates counterclockwise around the hinge, thus realizing the left and right movement of the perforated plate angle iron.

[0010] As a further improvement of this utility model, a connecting plate is provided on the side of the perforated plate angle iron, and the connecting plate is connected to the front joint bearing.

[0011] In this way, the connecting plate can be connected to the angle iron of the hole plate with bolts, and the connecting plate is connected to the connecting rod through the front joint bearing, which reduces the assembly accuracy between the angle iron of the hole plate and the connecting rod, and reduces the difficulty of manufacturing and assembling the parts.

[0013] Figure 2 This is a schematic diagram of the structure in the prior art.

[0014] Among them, 1 is the angle iron of the perforated plate, 2 is the connecting plate, 3 is the front joint bearing, 4 is the connecting rod, 5 is the rear joint bearing, 6 is the support plate, 7 is the main gear, 8 is the driven gear, 9 is the swing arm, 10 is the bearing with a handle, 11 is the cam of the perforated plate, 12 is the fixing block, and 13 is the return spring. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings:

[0016] like Figure 1 The diagram illustrates a perforated plate transmission mechanism for a fishing net machine, comprising a perforated plate angle iron 1 connected to a swing structure, which in turn is connected to a transmission structure. The swing structure includes a connecting rod 4, the front end of which is connected to the perforated plate angle iron 1 via a front joint bearing 3, and the rear end of which is connected to the front end of a swing arm 9 via a rear joint bearing 5. The middle of the swing arm 9 is hinged to a support plate 6, which is mounted on a frame. A handle bearing 10 is provided at the rear end of the swing arm 9, cooperating with the transmission structure. The front end of the swing arm 9 is connected to one end of a return spring 13, and the other end of the return spring 13 is connected to a fixed block 12 mounted on the frame.

[0017] The transmission structure includes a perforated plate cam 11 that mates with a shank bearing 10. The perforated plate cam 11 is sleeved on the driven shaft, and a perforated plate gear is also sleeved on the driven shaft. The perforated plate gear meshes with a main gear 7, which is sleeved on the main shaft. A connecting plate 2 is provided on the side of the perforated plate angle iron 1, and the connecting plate 2 is connected to the front spherical bearing 3.

[0018] In this invention, the main shaft is driven to rotate continuously by the motor of the fishing net machine, which causes the main gear 7 to rotate. The rotation of the main gear 7 drives the driven gear 8 to rotate. Since the driven gear 8 and the perforated plate cam 11 are mounted on the same driven shaft, the perforated plate cam 11 rotates simultaneously.

[0019] When the protruding part of the perforated plate cam 11 contacts the shank bearing 10 at the rear end of the swing arm 9, the swing arm 9 will rotate clockwise around its middle part. In this way, the rear end of the swing arm 9 rotates to the right and the front end of the swing arm 9 rotates to the left. The connecting rod 4 can move linearly from right to left through the rear joint bearing 5, and then the connecting plate 2 is driven by the front joint bearing 3 to move the perforated plate angle iron 1 linearly from right to left, thereby hooking the warp thread onto the upper hook.

[0020] When the protruding part of the perforated plate cam 11 disengages from the shank bearing 10 at the rear end of the swing arm 9, the swing arm 9 is no longer acted upon by the perforated plate cam 11. Instead, under the tension of the return spring 13, the swing arm 9 rotates counterclockwise around its center. Thus, the rear end of the swing arm 9 rotates to the left, and the front end rotates to the right, returning to its original position. During this process, the connecting rod 4 can move linearly from left to right through the rear joint bearing 5, and the connecting plate 2 is driven by the front joint bearing 3 to move the perforated plate angle iron 1 linearly from left to right, thereby hooking the warp thread onto the lower hook.

[0021] As the perforated plate cam 11 continues to rotate, the perforated plate angle iron 1 will also move back and forth in the left and right directions, so as to continuously hang the line with the upper and lower hooks.

[0022] This invention significantly reduces the number of connecting rods 4 and rocker arms, thereby effectively improving the accuracy of the intermediate transmission, reducing manufacturing costs, and making installation and disassembly more convenient.

[0023] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed herein, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
