Description

Technical Field

[0001] This invention relates to the technical field of wire drawing machines, and more particularly to a cylindrical automatic wire drawing machine with adjustable tension. Background Technology

[0002] Wire drawing machines, also known as wire extrusion machines, are widely used mechanical equipment in industrial applications, including machinery manufacturing, hardware processing, petrochemicals, plastics, bamboo and wood products, and wire and cable industries. Wire drawing machines can be categorized by their application into metal wire drawing machines (used for pre-processing of standard parts and other metal products), plastic wire drawing machines (specialized complete sets of equipment used in the plastics industry to produce various hollow and solid round or flat wires from raw materials such as polyester, nylon, polyethylene, polypropylene, and polyester chips for further processing), and bamboo and wood wire drawing machines (specialized equipment used in the bamboo and wood products industry to draw bamboo and wood fibers for further processing in the production of chopsticks, toothpicks, barbecue sticks, etc.).

[0003] Whether producing metal wire or nylon wire, wire drawing machines have specific length specifications. When a certain length is reached, workers need to replace the spools with new ones for winding. When replacing the spools, the wire ends need to be secured. Currently, workers usually use tape to stick the wire ends together. If the tape is not firmly attached, the wire ends will come loose. Once the wire ends come loose, the wire in front will become loose. If the wire is loose, it will come out of the groove of the roller, causing the wire to be worn during operation and affecting the quality of the wire. Summary of the Invention

[0004] The purpose of this invention is to provide a tension-adjustable cylindrical automatic wire drawing machine in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tension-adjustable cylindrical automatic wire drawing machine, comprising a base for a winding device in the wire drawing machine, a mounting plate fixedly disposed on one side of the base, a winding assembly mounted at the middle position of the side of the mounting plate, a mounting frame fixedly disposed on the upper end of the side of the mounting plate, a lead screw rotatably disposed on the lower end of the mounting frame, one end of the lead screw being connected to the output shaft of a first motor, a warning light mounted on the upper end of the mounting plate, a control box mounted on one side of the mounting plate, and a wire device mounted on the upper end of the mounting plate;

[0006] The wire-conducting device includes a mounting base threadedly connected to a lead screw. The mounting base is slidably connected to a mounting frame. Two fixed frames are mounted on the lower end of the mounting base. A sliding groove is formed in the middle of each of the two fixed frames. A guide rod is fixedly mounted in the middle of the sliding groove. A slider is slidably mounted on the upper end of the guide rod. A first spring is mounted on the lower end of the slider. A first pressure sensor is mounted between the first spring and the lower end of the sliding groove. A first rotating shaft is rotatably mounted on one side of the slider. A guide wheel is mounted between the two rotating shafts. Movable rods are hinged to the outer walls of the two fixed frames. A connecting rod is fixedly mounted between the two movable rods. A cable detection component is mounted in the middle of the connecting rod. A cable clamping component for protecting the guide wheel is mounted on the lower end of one end of the mounting base.

[0007] Furthermore, the clamping assembly consists of two symmetrical extrusion groups. Each extrusion group includes a telescopic rod fixedly connected to a mounting base. A third spring is sleeved around the telescopic rod. The telescopic rod consists of a guide tube and a piston cylinder. A mounting block is fixedly connected to one end of the telescopic rod. A connecting tube is fixedly connected to one side of the outer wall of the mounting block. The connecting tube communicates with the telescopic rod and the guide tube. A rotating cylinder is rotatably connected to the outer wall of the connecting tube. The rotating cylinder consists of an upper rotating cylinder and a lower rotating cylinder, which are connected by threads. The rotating cylinder has a circular cross-section, and a piston cylinder is sleeved on the lower end of the side wall of the rotating cylinder. The rotating drum has a rubber sleeve, and a clamping sleeve is provided at the upper end of the side wall. The clamping sleeve is made of a hard material with a regular polygonal cross-section and anti-slip texture on each face. The lower end of the rotating drum is shaped like a frustum cone. A damping assembly is fixedly installed at the lower end of the connecting pipe. A storage cavity for use with the damping assembly is opened inside the rotating drum. A second pressure sensor is symmetrically arranged on the surface of the storage cavity. An air cylinder is fixedly installed at the lower end of the damping assembly. A threaded rod is threadedly connected to the lower end of the air cylinder. A piston is rotatably connected to the upper end of the threaded rod. The lower end of the threaded rod passes through the rotating drum and is equipped with a handwheel. The threaded rod does not contact the rotating drum.

[0008] Furthermore, the damping assembly includes a housing, an extrusion rod is slidably disposed inside the housing, a sealing plug is disposed at one end of the extrusion rod inside the housing, a rubber block is disposed at the other end of the extrusion rod, and a limiting block is disposed inside the housing to limit the movement distance of the extrusion rod.

[0009] Furthermore, the wiring detection assembly includes a second guide cylinder and a second connecting block rotatably disposed in the middle of the connecting rod. The second guide cylinder has a wiring hole in the middle, and two sets of horizontal rollers and two sets of vertical rollers are respectively disposed at the upper and lower ends of the wiring hole. A laser pointer is installed at the lower end of the second guide cylinder.

The circular conductive piece is connected to the middle position of the arc-shaped resistor through a conductive strip. The conductive strip is perpendicular to the connecting rod. One of the conductive groups contacts the circular conductive piece, and the other conductive group contacts the middle position of the arc-shaped resistor.

[0010] Furthermore, the control box is equipped with a processor, a control panel, and a detection module for detecting resistance. The detection module operates on the same principle as a multimeter for detecting resistance. The two sets of conductive groups are connected to the detection module. The processor input is electrically connected to the outputs of the detection module, the control panel, the first pressure sensor, and the second pressure sensor. The processor output is electrically connected to the inputs of the warning light, the laser pointer, the first motor, and the second motor.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In this invention, the thread is wound around the outer wall of the rubber sleeve, creating friction between the rubber sleeve and the thread. Then, the handwheel is rotated to bring the rotating drum close to the rubber sleeve and compress and deform it, thereby locking the thread in place and preventing it from slipping out.

A laser pointer 805 is installed at the lower end of the second guide cylinder 801. The center of the laser pointer 805 and the groove of the guide wheel 503 are located on the same plane.

The second guide cylinder 801 has a circular cavity inside that is used in conjunction with the turntable 807. The turntable 807 is not conductive. Two sets of conductive groups 808 are arranged inside the circular cavity. An arc-shaped resistor 8071 is fixedly arranged on the outer wall of the turntable 807. A circular conductive piece 8073 is fixedly arranged at the central axis of the turntable 807. The circular conductive piece 8073 is connected to the middle position of the arc-shaped resistor 8071 through a conductive strip. The conductive strip is arranged perpendicularly to the connecting rod 509. One of the conductive groups 808 is in contact with the circular conductive piece 8073, and the other conductive group 808 is in contact with the middle position of the arc-shaped resistor 8071.

[0031] Furthermore, the control box 3 is equipped with a processor, a control panel, and a detection module for detecting resistance. The detection module works on the same principle as a multimeter for detecting resistance. Two sets of conductive groups 808 are connected to the detection module. The processor input is electrically connected to the outputs of the detection module, the control panel, the first pressure sensor 508, and the second pressure sensor 7011. The processor output is electrically connected to the inputs of the warning light 4, the laser pointer 805, the first motor, and the second motor.

[0032] Furthermore, the winding assembly 6 consists of a second motor, a rotating shaft, and an I-beam reel.

[0033] Working principle:

[0034] Wiring: When the I-beam needs to be edged after replacing it with a new one, first control the first motor and laser pointer 805 through the control panel. The output shaft of the first motor drives the wire guide device 5 to move. When the laser pointer 805 beam contacts and is parallel to the inner wall of one side of the I-beam, the first motor stops working and the data is recorded (as the first limit position of the wire guide device 5). Similarly, record the position of the inner wall of one side of the other side of the I-beam.

[0035] Clamping: When changing the I-beam reel, first stop the machine. Grasp the wire at both ends of the wire clamping assembly 7 with both hands and control the second motor (usually the machine has a foot pedal to control the second motor). Slowly loosen the wire, then wrap the wire around the outer wall of the rubber sleeve 702 once. Stop the second motor and loosen the wire at the front end of the wire clamping assembly 7. Keep the wire taut with your other hand. Rotate the handwheel to rotate the threaded rod 708. The threaded rod 708 is threadedly connected to the air pump 707, thus pushing the piston to move. Internal gas enters the housing 7061, pushing the sealing plug 7065 inside the housing 7061 against the side wall of the receiving cavity. Then the gas enters the connecting pipe 704 and from the connecting pipe 704 into the telescopic rod 705. The telescopic rod 705 extends and drives the two rotating drums 701 to move closer together through the connecting pipe 704, causing the two rubber sleeves 702 to be squeezed and deformed. At the same time, the outer sides of the two clamping sleeves 703 are in contact with each other. Since the cross-section of the clamping sleeve 703 is a regular polygon, it has a self-locking ability. At this time, the wire can be cut as needed and the I-beam wheel can be replaced.

[0036] Inspection: At the beginning of production, there may be errors in the data input. When the set data is deviated, if the wire device 5 moves beyond the length of the I-beam, the wire cannot be wound beyond the length of the I-beam when it rewinds to the surface of the I-beam, causing the wire to accumulate at one end of the I-beam. As the guide wheel 503 continues to move, the wire will tilt severely. When the wire tilts, it will cause the second guide cylinder 801 to tilt as well. When the second guide cylinder 801 tilts, the conductive group 808 in contact with the arc-shaped resistor 8071 will change and will not be in the middle position of the arc-shaped resistor 8071, causing a change in resistance. The detection module detects the change in resistance and transmits the signal to the processor. The processor controls the warning light 4 to flash to give a warning, and at the same time controls the first motor to reverse (here, reversal means rotating in the opposite direction to the current state) to prevent the wire from accumulating too much at one end of the I-beam and to prevent the wire from being pressed or skipped.

[0037] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
