Technical Field

[0001] This invention relates to the field of electric welded wire mesh machine technology, and specifically to a wire feeding device for an electric welded wire mesh machine. Background Technology

[0002] In modern industrial production, metal mesh, as an important structural and functional component, is widely used in many fields such as construction, metallurgy, chemical industry, aerospace, and electronic equipment. From protective netting and filter netting in the construction industry to shielding netting in electronic equipment, from screening netting in the metallurgical industry to special structural netting in the aerospace industry, the demand for metal mesh is not only large, but the requirements for its precision, strength, and welding quality are also increasing.

[0003] Existing electric wire mesh welding machines require sequential steps such as longitudinal wire feeding, transverse wire feeding, welding, and material discharge during welding. However, in the existing technology, longitudinal / transverse wire feeding either relies on manual operation or can only achieve semi-automatic feeding through manual intervention. It is impossible to achieve full-process automated linkage control based on the real-time status of the production process (such as the position of metal wire, welding progress, material discharge feedback, etc.), resulting in low production efficiency and large errors. Summary of the Invention

[0020] The technical solution provided by this invention has the following advantages compared with the known prior art:

[0021] 1. By integrating the detection and control circuits through the PLC controller, the PLC receives the resistance signals from the detection mechanism and the feedback from the pressure sensor in real time, and uniformly schedules the action sequence of components such as the electric telescopic rod and motor. The longitudinal wire feeding, transverse wire feeding, welding, and material discharge links form a closed-loop linkage through mechanical coupling (such as one-way gear transmission), which can complete the entire process without manual intervention, avoiding the time loss and errors of manual operation, and significantly improving production efficiency.

[0022] 2. The longitudinal wire feeding is driven by the first motor to move the feed cylinder laterally. The meshing of the first one-way gear and the toothed plate enables the longitudinal feed roller to rotate in one direction, accurately feeding out the metal wire. During reset, the one-way gear prevents the roller shaft from reversing and avoids the metal wire from retracting. After the wire is fed, the second electric telescopic rod pushes the alignment block to calibrate the position of the metal wire. Its inclined top pushes the metal wire against the side wall of the push block. Then, the reciprocating screw drives the push block to complete the automatic laying. The entire process does not require manual placement and positioning, simplifying the feeding process and reducing errors.

[0023] 3. When the discharge mechanism pulls the metal mesh, the third toothed plate at the top of the pulling block meshes with the second one-way gear, driving the rotating rod to rotate the transverse feeding roller, so that the wire feeding action is synchronized with the discharge progress. The start and stop time of the third motor is preset to pull one mesh distance, ensuring that the intermittent wire feeding accurately matches the production rhythm. The transverse wire feeding can be completed without an additional power source. Energy efficiency is achieved through mechanical transmission coupling, reducing equipment energy consumption.

The outer wall of the rotating rod 94 is fitted with two symmetrical second one-way gears 1010. The second one-way gears 1010 mesh with the third toothed plate 1013, and the teeth of the third toothed plate 1013 face upward.

[0049] The working principle of this invention is as follows:

[0050] The metal wire to be processed is placed in the first wire storage box 815 and the second wire storage box 93. The equipment is started, the PLC controller is in standby mode, and all components such as electric telescopic rods and motors are ready. The interval time of each step is a pre-tested time and is input into the PLC controller (excluding the detection circuit and the detection of the first pressure sensor and the second pressure sensor).

[0051] Next, the longitudinal wire feeding process begins. The metal wire in the first wire storage box 815 enters the feed cylinder 81 through the connecting port and the wire inlet 813, and falls into the longitudinal storage groove 83 on the outer peripheral wall of the longitudinal feed roller 82. The first motor 85 is started, which drives the threaded rod 86 to rotate, and drives the feed cylinder 81 to move laterally along the mounting platform 1 through the connecting block 87 and the connecting column. When the feed cylinder moves to the end, the preset program controls the first motor 85 to reverse the drive, so that the feed cylinder is reset. Due to the one-way meshing characteristic of the first one-way gear 811 and the first toothed plate 812 (similar to a ratchet mechanism), the longitudinal feed roller 82 will not rotate in reverse when the feed cylinder is reset, thus preventing the metal wire from retracting.

[0052] Since the first one-way gear 811 on the outer wall of the longitudinal feeding roller 82 meshes with the first toothed plate 812 on the outer wall of the support plate 4, when the feeding cylinder 81 moves laterally, the first one-way gear 811 rolls on the first toothed plate 812, further driving the longitudinal feeding roller 82 to rotate, and feeding the metal wire in the longitudinal storage groove 83 out from the wire feeding port 824 in sequence. The fed metal wire falls on the placement block 816 and the placement push block 821 at the top of the mounting platform 1. Then, the second electric telescopic rod 823 is activated, pushing the alignment block 814 to move upward (the top of the alignment block 814 is inclined, tilting downward from the end away from the placement block 816 toward the end close to the placement block 816, and the bottom is straight), thereby calibrating the position of the metal wire (so that one end of the metal wire abuts against the side wall of the placement push block 821).

[0053] Then, the second motor 819 is started to drive the reciprocating screw 817 to rotate, so that the reciprocating plate 820 moves laterally along the mounting platform 1 under the limit of the limit rod 818. The placement push block 821 at the top of the reciprocating plate 820 pushes the metal wire on the placement block 816 through the two conveying wheels 74 in the same fixed frame 71, and then pushes it into the electrode base plate 62 to complete the laying of the longitudinal metal wire. When processing starts for the first time (only at the beginning of processing), the metal wire is pushed forward by the placement push block 821 (the distance pushed each time is also preset). After the first metal wire is loaded, the metal wire is pulled by the discharge mechanism 10 to complete the processing and welding.

[0054] During this process, the detection mechanism 7 operates synchronously. When the metal wire passes through the conveyor wheel 74, the distance between the conveyor wheels 74 increases, which in turn causes the slider 73 below to drive the L-shaped conductive sheet 78 to slide on the resistor plate 77 and change the resistance value. This signal is transmitted to the PLC controller to determine whether the metal wire conveying and position are normal. If there is an abnormality, it is adjusted in time. In subsequent operation, if the resistance value is detected to return to normal, it means that the metal wire has been completely removed from between the two conveyor wheels 74. Therefore, new metal wire is needed to replenish it, and then the above process is repeated for longitudinal feeding.

[0055] After the longitudinal wire feeding is completed, the transverse wire feeding stage begins (the power source for transverse wire feeding is within the discharge mechanism 10). The metal wire in the second wire storage box 93 falls into the transverse storage groove 92 on the outer periphery of the transverse discharge roller 91 through the wire outlet and the inclined wire shell 96. The rotation of the transverse discharge roller 91 causes the metal wire to fall onto the inclined plate, thereby conveying the metal wire to the electrode base plate 62. The metal wire is then prevented from shifting position by the limiting post 68, so that it is laid crosswise with the metal wire laid longitudinally on the electrode base plate 62. Then, by activating the two third electric telescopic rods 97, the alignment block 814 is pushed to squeeze the metal wire, thereby achieving secondary positioning. When both first pressure sensors sense the pressure change, they transmit electrical signals to the PLC controller. The PLC controller controls the two third electric telescopic rods 97 to retract, and then activates the first electric telescopic rod 66. Subsequently, welding is controlled by the PLC controller.

[0056] The first electric telescopic rod 66 is started by the PLC controller. The control head 65 moves downward along the sliding groove 64 at the top of the protective cover 63 through the connecting plate 67, so that the electrode head 61 fixed at the bottom of the control head 65 contacts the electrode base plate 62 at the top of the mounting platform 1. Welding is performed at the intersection to complete the welding of one mesh of the metal mesh. After the welding is completed, the first electric telescopic rod 66 drives the electrode head 61 to reset. The above wire feeding and welding steps are repeated until the welding of the entire metal mesh is completed.

[0057] First, the fourth motor 109 is started, which drives the mesh hook 101 to rotate and hook the welded metal mesh through the rotating shaft. Then, the third motor 106 is started, which drives the bidirectional gear 105 to rotate. Since the bidirectional gear 105 meshes with the second toothed plate 103 on the inner wall of the discharge trough 102, it drives the N-shaped frame 104 to move longitudinally along the mounting platform 1 in the discharge trough 102, which in turn drives the mounting strip 107 and the mesh hook 101 to move. Driven by the third motor 106, the mesh hook 101 pulls the metal mesh along the discharge trough 102 and pulls it out of the discharge frame 3 (the start and stop time of the third motor 106 is preset so that it can pull the metal mesh to move the distance of one grid).

[0058] At the same time, when the hook 101 moves, the second one-way gear 1010 on the outer wall of the rotating rod 94 meshes with the third toothed plate 1013 at the top of the pulling block 1012, driving the rotating rod 94 to rotate, so that the transverse feeding roller 91 intermittently feeds the wire, preparing for the next production cycle.

[0059] When the installation bar 107 moves to the end of the discharge frame 3, the installation bar 107 will squeeze the second pressure sensor. At this time, the second pressure sensor will send an electrical signal to the PLC controller. Then, the PLC controller will control the third motor 106 and the fourth motor 109 to reverse, so that the mesh hook 101 will no longer hook the metal mesh. The reverse rotation of the third motor 106 will move the installation bar 107 to the initial position (in this process, the second one-way gear 1010 and the first one-way gear 811 have the same function). Then, the fourth motor 109 will be restarted, so that the mesh hook 101 will hook the metal mesh again and discharge the material.
