AI Technical Summary
Existing wire drawing machines cannot accurately measure the weight of the coil when drawing finished products, requiring operators to make judgments based on their experience. This results in the equipment needing to be repeatedly stopped to achieve the weight required by the customer.
A weighing mechanism for finished wire drawing machines was designed. Through sensors and motor drive structure, the number of rotations of the winding roller is precisely controlled. Combined with the control panel settings, the winding length is automatically adjusted to achieve the target coil weight.
It enables automatic equipment shutdown when the required pallet weight is reached, avoiding manual judgment and repeated pauses, thus improving production efficiency and accuracy.

Technical Field
[0001] This utility model relates to the technical field of metal products, specifically a weighing mechanism for finished products drawn by a wire drawing machine. Background Technology
[0002] When the wire drawing machine is drawing finished products, it needs to break the wire when the coil weight reaches the customer's required weight. The existing equipment cannot measure the coil weight, so the operator needs to judge whether the weight is close to the customer's required standard based on experience. When it is expected to be close to the coil weight, the machine needs to be stopped to weigh it. This process needs to be repeated several times to accurately reach the customer's required coil weight. Utility Model Content

[0023] The following is a reference to the appendix. Figures 1-5 The preferred embodiments of this utility model are described below. Those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.
[0024] This utility model proposes a weighing mechanism for finished products drawn by a wire drawing machine. Before use, the pair of sensitive elements of a pair of sensors 4 are aligned at one end relative to each other, such as... Figure 1As shown, when using this device, open the movable door 13, align the pair of sliding grooves of the winding drum 7 with the corresponding sliding rods 14 of the winding roller 6, push the winding drum 7, the pair of sliding grooves slide along the corresponding sliding rods 14, and the inner wall of the winding drum 7 slides along the rotating drum of the winding roller 6. Place one disc of the winding drum 7 against one side of the rotating disc of the winding roller 6, pass the starting end of the desired winding thread through the threading loop 12, fix one end of the winding thread on the winding roller 6, and tension the winding thread to make it taut. At this time, the winding thread is stretched out by 50cm. Close the movable door 13 and fix the movable door 13 with the buckle. A set of ball bearings 1... 5. One end of the winding roller 6 is pressed against the outside of the other disc of the winding drum 7. At this time, the other end of the winding roller 6 is inserted into the groove of the movable door 13. Calculate the length of fine wire corresponding to the current winding weight as needed. Set the number of rotations of the gear ring 1 through the control panel 2. Subtract 1m from the required length (i.e., if 100m is needed, set it to 99m, meaning the gear ring 1 needs to rotate 198 times). Start the motor 5 and a pair of sensors 4. The motor 5 drives the gear 3 to rotate, and the gear 3 drives the reciprocating screw 8 and the meshing gear ring 1 to rotate. The reciprocating screw 8 drives the slider 11 to slide back and forth along the reciprocating screw. Block 2 11 drives the threading coil 12 to slide back and forth, and slider 2 11 drives slider 1 10 to slide back and forth along guide rod 9. Gear ring 1 drives cross stabilizer rod to rotate, and cross stabilizer rod drives winding roller 6 to rotate via turntable. Cross stabilizer rod drives corresponding sensor 4 to move in a circular trajectory. When one sensor 4 rotates one revolution and aligns with the sensitive element of another sensor 4, one revolution is counted. Winding roller 6 drives winding drum 7 to rotate via a pair of slide rods 14. Another disc of winding drum 7 rotates and slides along a set of balls 15. Winding drum 7 rotates to wind fine thread, and threading coil 12 slides back and forth to wind fine thread. The thread is evenly wound around the cylinder of the winding drum 7, avoiding the thread from being completely wrapped in the same position. When the winding is finished, the motor 5 stops and the thread is cut off from the inlet end (i.e., 50cm). At this point, the winding is finished. Open the latch and the movable door 13, remove the winding drum 7 after winding, and put in the next winding drum 7 for winding. The operation process is the same and will not be described again. This device calculates the corresponding number of turns according to the weight requirement of the winding, and sets the number of rotations of the winding roller through the control panel to achieve the corresponding coil weight. The device can accurately stop when the coil weight reaches the set point without repeatedly pausing.
