Description

Technical Field

[0001] The utility model belongs to the technical field of welding wire counting, and in particular relates to an automatic welding wire dispensing and counting device. Background Art

[0002] At present, the degree of automation in welding material management is still very low, and there is a lack of equipment for intelligent management without personnel participation. Manual counting of welding wire and distribution to users is easy to count wrong and labor-intensive. When there are many people who need to use it, they need to wait in line. Each time the welding material manager needs to be present to confirm the identity of the user and the number of distribution. For this reason, an automatic welding wire distribution counting device is used to realize the automatic counting and distribution of welding wire. The automatic welding wire distribution counting device consists of a storage device, a feeding mechanism, a conveying device, a counting system, a discharge device, a control system, a control display screen and a face recognition system. The welding wire is transmitted through the feeding mechanism and the conveying device, and then counted through the technical system, and the welding wire discharge control is realized through the discharge device. At the same time, the automatic welding wire distribution counting device adopts a feeding mechanism with two sets of middle wheels as the main and two side wheels as the auxiliary to solve the problem of difficulty in feeding soft and slender materials and easy feeding errors. The use of automatic welding wire distribution equipment can reduce the number of welding material management personnel, reduce labor intensity, and improve efficiency. The welding wire collection is more flexible and convenient after remote control.

[0003] The existing automatic wire dispensing and counting equipment has the following defects when performing automatic wire dispensing and counting:

[0004] (1) Due to the inconsistent length specifications of welding wire, when counting and dispensing, the welding wire position is prone to shift to one side after being unloaded from the storage bin, resulting in the center position of the welding wire not being aligned with the main feeding wheel mechanism, and then the welding wire is prone to tilt during transmission. For this reason, we propose an automatic welding wire dispensing and counting device. Utility Model Content

[0005] The purpose of the utility model is to provide an automatic welding wire dispensing and counting device to solve the problem that the welding wire position is prone to one-side deviation during the counting and dispensing operation of welding wires of other specifications proposed by the automatic welding wire dispensing and counting device proposed in the above background technology, resulting in the center position of the welding wire not being aligned with the main feeding wheel mechanism, and then the welding wire is prone to tilting during the transmission process.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic welding wire dispensing and counting device, comprising a frame, a feeding drive mechanism is installed at the inner center of the frame, a feeding driving wheel is arranged on the feeding drive mechanism, synchronous wheel groups are respectively installed on both sides of the feeding drive mechanism, a feeding auxiliary wheel is installed on the synchronous wheel group, a conveyor belt is respectively installed on the feeding auxiliary wheel and the feeding driving wheel, a storage bin is installed at one end of the frame, a material plate is arranged at the bottom of the material port of the storage bin, a face recognition touch control unit is arranged on one side of the storage bin, a discharging mechanism is arranged on one side of the front end of the feeding drive mechanism, a photoelectric counter-shooting counting mechanism is arranged on the other side of the front end of the feeding drive mechanism, a whole material adjustment mechanism is arranged on the top of the feeding drive mechanism, a double-axis motor is fixed at the bottom center of the material plate, two screws are symmetrically installed on the output end of the double-axis motor, two adjustment plates are symmetrically arranged on the material plate, a mounting frame is installed on one side of the adjustment plate, a screw hole is opened on the surface of the mounting frame, and the screw hole and the screw are connected by threads.

[0007] Preferably, a guide groove is provided on the end surface of the mounting frame, and a guide rail block is slidably connected to the inner side of the guide groove, and the guide rail block is fixed on the bottom end surface of the material plate.

[0008] Preferably, the longitudinal section of the guide rail block is a convex structure, and the cross section of the guide rail block is a rectangular structure.

[0009] Preferably, limit blocks are fixed at both ends of the bottom of the guide rail block.

[0010] Preferably, a spherical groove is formed on the bottom surface of the adjustment plate, and a ball is embedded in the spherical groove.

[0011] Preferably, a avoidance hole is opened on the surface of the mounting frame, and the central axes of the avoidance hole and the screw hole coincide with each other.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] (1) Through the designed adjustment plate, mounting frame, dual-axis motor and screw, the adjustment plates are symmetrically arranged on both sides of the material plate. The adjustment plates are connected to the dual-axis motor through the mounting frame and the screw. When the storage bin is feeding welding wires of different lengths, the dual-axis motor drives the screws at both ends to rotate simultaneously. The screws at both ends are simultaneously screwed and adjusted with the corresponding mounting frames, thereby adjusting the spacing between the two adjustment plates, so that when the welding wire is unloaded from the storage bin to the material plate, the welding wire slides between the two adjustment plates, and the bending end and the plane end of the adjustment plate are adjusted to achieve the center position of the welding wire extrusion adjustment. The position can avoid the welding wire from being tilted when it is not in the center position for loading. The guide block and guide groove are designed to place the guide block inside the guide groove to guide the movement of the mounting frame. The limit block is designed to limit the position to avoid excessive adjustment that causes one end of the mounting frame to fall off the guide block. The ball is designed to be embedded in the bottom of the adjustment plate to lubricate and reduce the friction resistance between the bottom surface of the adjustment plate and the surface of the material plate, making the adjustment smoother. The avoidance hole is designed to avoid the end of the screw being blocked by one end of the mounting frame during adjustment, thereby affecting the adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

Through the designed adjustment plate 11, mounting frame 12, double-axis motor 17 and screw 15, the adjustment plates 11 are symmetrically arranged on both sides of the material plate 5. The adjustment plate 11 is connected to the double-axis motor 17 through the mounting frame 12 and the screw 15. When the storage bin 2 is feeding welding wires of different lengths, the double-axis motor 17 drives the screws 15 at both ends to rotate simultaneously. The screws 15 at both ends are simultaneously screwed and adjusted with the corresponding mounting frames 12, so as to adjust the spacing between the two adjustment plates 11, so that when the welding wire is unloaded from the storage bin 2 to the material plate 5, the welding wire slides between the two adjustment plates 11, and the bending end and the plane end of the adjustment plate 11 are used to realize the adjustment of the center position of the welding wire extrusion, so as to avoid the welding wire being not in the center position for feeding and being easily tilted. The screw hole 16 and the screw 15 are connected by threads.

[0023] In this embodiment, preferably, a guide groove 14 is opened on the end face of the mounting frame 12, and a guide block 19 is slidably connected to the inner side of the guide groove 14. Through the designed guide block 19 and guide groove 14, the guide block 19 is placed inside the guide groove 14 to guide the movement of the mounting frame 12.

[0025] The working principle and use process of the utility model: When the utility model is in use, the management personnel can open the welding wire storage bin 2 and put in welding wire in batches only after the face recognition touch unit 4 performs face recognition, and close the bin door. When the user takes the welding wire, first the face recognition confirms the identity information, and the display screen of the face recognition touch unit 4 can display the user's predetermined quantity, or the quantity can be manually input. After pressing the release button, the welding wire in the storage bin 2 falls onto the material plate 5, and with the cooperation of the feeding drive mechanism 7 and the synchronous wheel group 10, the conveyor belt 6 is driven to rotate, and then the welding wire is transported by the conveyor belt 6. During the transportation process, the welding wire is sorted by the sorting plate on the sorting adjustment mechanism 3, and then counted by the photoelectric counter-shooting counting mechanism 8. When the release quantity is about to be reached, the conveyor belt 6 slows down, and when the release quantity is just reached, the conveyor belt 6 stops, and the discharging mechanism 21 is started, wherein the discharging mechanism 21 is provided with a discharging inclined block, which is driven by the electric cylinder to separate the counted welding wire and the uncounted welding wire, and then The welding wire delivery device has been counted, and the control system records the personnel information and the number of releases. At this time, the device completes a release counting action. When the amount of welding wire in the storage bin is less than a certain level, the material level sensor at the bottom of the silo is used for sensing, and the device will send a signal to remind the administrator to add material. This device can be connected to a mobile phone through an APP to achieve remote supervision and control. When the welding wire is fed through the storage bin 2, the dual-axis motor 17 drives the screws 15 at both ends to rotate simultaneously, wherein the model of the dual-axis motor 17 is 0K35STH20-0404B, and the screws 15 at both ends are simultaneously screwed and adjusted with the corresponding mounting brackets 12, thereby adjusting the spacing between the two adjustment plates 11 to match the spacing and the length of the welding wire. When the welding wire is unloaded from the storage bin 2 to the material plate 5, the welding wire slides between the two adjustment plates 11, and the bending end and the plane end of the adjustment plate 11 are used to adjust the center position of the welding wire to avoid the welding wire being not in the center position for feeding and easily tilting.
