Detailed Implementation
[0027] In view of the shortcomings of the prior art, the inventor of this case, through long-term research and extensive practice, has come up with the technical solution of this utility model. The following will further explain the technical solution, its implementation process, and its principles.
[0028] like Figure 1 , Figure 2 As shown, this utility model discloses a line knotting device, including a knotting unit 100. The knotting unit 100 includes a clamping component 1, a knotting component 2, a clamping component 6, and a cutting component 3. Before knotting, an external carrier moves the line to the clamping component 1. The clamping component 1 is used to clamp at least one end of the line and move that end of the line. The line is in a taut or slightly taut state between the carrier and the clamping component. Specifically, as shown... Figure 5As shown, the gripping assembly 1 includes a gripper 11 and a gripper cylinder 12. The gripper cylinder 12 is used to drive the gripper 11 to open or close. A third drive assembly 13 is provided on one side of the gripper cylinder 12. Under the drive of the third drive assembly 13, the gripper moves towards or away from the gripping assembly to pull the line. When the carrier moves the line to the gripping assembly 1, the third drive assembly 13 drives the gripper and the gripper cylinder 12 to move to the carrier. The gripper cylinder 12 drives the gripper to clamp one end of the line. The third drive assembly 13 drives the gripper cylinder 12 and the gripper to move away from the carrier, so that the line is in a taut or slightly taut state between the carrier and the gripper.
[0029] The knotting component 2 is at least used to wrap around the line, rotate the line to form a circle, and pass one end of the line through the circle formed by the line; specifically, as shown in the example... Figure 3 As shown, the knotting assembly 2 includes a clamping assembly 21, a rotation drive assembly 22, and a first drive assembly 23. The clamping assembly 21 is at least used to hook and clamp the line, the rotation drive assembly 22 is at least used to drive the clamping assembly 21 to rotate so that the line wraps around the clamping assembly 21, and the first drive assembly 23 is at least used to drive the clamping assembly 21 to move so that one end of the line passes through the loop formed by the line.
[0030] More specifically, such as Figure 4 As shown, the clamping assembly 21 includes a first clamping arm 211 and a second clamping arm 212, which are hinged together. A second driving assembly 213 is connected to one side of the first clamping arm 211 via a connector. The driving end of the second driving assembly 213 is fixedly connected to the connector, which is hinged to the first clamping arm 211. Under the drive of the second driving assembly 213, the first clamping arm 211 and the second clamping arm 212 open or close relative to each other. The second driving assembly 213 includes a linear cylinder or motor and a lead screw. In this embodiment, the second driving assembly 213 includes a linear cylinder, and the driving end of the linear cylinder is fixedly connected to the connector. To hook the line and prevent it from falling off the side wall of the clamping assembly 21 during rotation, a hook groove 214 is provided on one side of the first clamping arm 211. The hook groove 214 is at least used to hook the line.
[0031] More specifically, the rotary drive assembly 22 may include a rotary cylinder or a rotary motor, and in this embodiment, the rotary drive assembly 22 includes a rotary motor.
[0032] More specifically, the first drive assembly 23 may include a linear cylinder or a motor and a lead screw; in this embodiment, the first drive assembly 23 includes a motor and a lead screw. To ensure better balance of the knotting assembly 2 during movement, a slider and a slide rail are provided between the fixing frame 4 and the knotting assembly 2, and the knotting assembly 2 and the fixing frame 4 are slidably connected by the slider and the slide rail.
[0033] Based on the above, the cutting component 3 is at least used to cut off the excess lines after knotting. The lines can be cut by scissors or by heat-setting; in this embodiment, the lines are cut by heat-setting. Specifically, such as... Figure 6 As shown, the cutting component 3 includes a resistance sheet 31. A heating component 32 is disposed on one side of the resistance sheet 31. The heating component 32 is used to heat the resistance sheet 31 so that the resistance sheet 31 burns the wire. Specifically, the heating component 32 includes a copper sheet, which is connected to a power source via a wire. When the copper sheet is energized, it heats up, thereby heating the resistance sheet 31. A fourth driving component 33 is disposed on one side of the heating component 32. Under the drive of the fourth driving component 33, the resistance sheet 31 moves towards or away from the clamping component. When the knotted wire end needs to be cut, the fourth driving component 33 drives the resistance sheet 31 and the heating component 32 to move towards the clamping component 21 to burn the wire.
[0034] Based on the above, such as Figure 1 As shown, the line knotting device also includes a fixing frame 4. To improve knotting efficiency, two knotting units 100 are provided on the fixing frame 4. The two knotting units 100 are used to knot the two ends of the line respectively. In this application, the two knotting units 100 simultaneously knot the two ends of the line, thereby improving knotting efficiency.
[0035] In some implementations, a collecting component 5 is provided below the clamping component, the collecting component 5 being used at least to collect the cut thread ends. Specifically, such as... Figure 7 As shown, the collection component 5 includes a collection hopper 51, which is connected to a suction gun 52 via a pipe. The cut lines move downward under the suction of the suction gun 52 to collect the cut lines.
[0036] Working principle:
[0037] When the carrier moves the line to the clamping assembly 1, both knotting units 100 operate simultaneously. Specifically, the clamping assembly 6 clamps the line on the carrier, and the clamping assembly 1 clamps one end of the line on the carrier and moves that end away from the carrier, so that the line is taut or slightly taut between the carrier and the clamping assembly 1. The first driving assembly 23 drives the clamping assembly 21 to move to the line, so that the hook groove 214 on the first clamping arm 211 hooks the line. Then, the rotation driving assembly 22 drives the clamping assembly 21 to rotate. At this time, the first clamping arm 211 and the second clamping arm 211... Arms 212 open relative to each other. Driven by the rotation drive assembly 22, the wire wraps around the clamping assembly 21. Then, the second drive assembly 213 drives the first clamping arm 211 and the second clamping arm 212 to close relative to each other and clamp the wire. Then, the first drive assembly 23 drives the clamping assembly 21 to move backward, so that one end of the wire passes through the loop formed by the wire and ties a knot. The fourth drive assembly 33 drives the heated resistance plate 31 to move towards the wire and burn off the wire. The first clamping arm 211 and the second clamping arm 212 open relative to each other, and the burn-off excess wire falls into the collection hopper 51.
[0038] The knotting component in this application can automatically knot one end of the line, replacing manual knotting and improving work efficiency; the two knotting units in this application simultaneously knot the ends of the line, further improving work efficiency; the cutting component in this application replaces manual cutting of excess thread ends, saving manpower; the collecting component in this application can collect the cut thread ends, keeping the environment tidy and preventing the mess of thread ends from affecting the normal operation of the equipment; at the same time, this application has a simple structure, flexible operation, and low cost.
