Description

Technical Field

[0001] The present invention relates to a PET welding grid suitable for use, and more particularly to a fully automatic tape feeding device for a welding device. Background Art

[0002] PET polyester geogrid is used in civil engineering such as highway, retaining wall reinforcement, high slope treatment, etc., and products for water conservancy projects exposed to the outside world.

[0003] PET polyester biaxially oriented welded geogrid is made of polyester as the main material, adding anti-aging agents and other additives, and is mechanically stretched at a low multiple to form refined ribs, which are arranged at right angles in the plane of longitude and latitude, and are formed into a geosynthetic material by special ultrasonic welding. According to the engineering needs, different mesh diameters, rib widths and thicknesses are used to change the tensile strength of the rib tape.

[0004] When preparing PET polyester geogrid, the grid is formed by welding and combining PET polyester strips.

[0005] However, in the existing equipment, the strip is fed by a person through a core-piercing die. During the tape feeding process, problems such as tape running, tape deviation, and insufficient tape feeding will occur, resulting in production problems such as welding deviation, repeated tape feeding, and no-tape welding, which not only affect the product quality, but also greatly reduce the work efficiency and increase the labor intensity.

[0014] Preferably, a first inductor is fixedly provided at the lower part of one side of the fixed pneumatic traction mechanism, and a second inductor is fixedly provided at the lower part of one side of the mobile pneumatic traction mechanism. Both the first inductor and the second inductor are located in the middle - lower part of the threading hole.

[0020] According to an embodiment of the present disclosure, the automatic tape feeding device of the present invention realizes the transportation of the PET strip through the fixed pneumatic traction mechanism and the moving pneumatic traction mechanism. And the fixed pneumatic traction mechanism and the moving pneumatic traction mechanism realize the transportation and maintain the horizontal stability of the PET strip through air pressure, that is, high-pressure gas is ejected through the air injection holes inside the air cavity to maintain the stability of the PET strip. And the moving pneumatic traction mechanism clamps the PET strip through high-pressure gas, which is convenient for pulling and moving the PET strip. And in order to maintain the stability of the PET strip, the pressing plate is pushed by high-pressure gas, so that the pressing plate can press and fix the PET strip to maintain the stable transportation of the PET strip. And an adjusting block is arranged inside the threading hole, and the adjusting block is adjusted through the first screw rod, which is convenient for realizing the threading and transportation of PET strips of different sizes;

[0021] In order to ensure that the pressing plate can stably press and fix the strip for easy traction, the elastic plate contacts with the fixed pneumatic traction mechanism, so that the elastic plate is squeezed by force. Then the top plate can move inside the adjusting cavity, and then the top plate can contact and collide with the first contact block on the second screw rod through the second contact block, so that the top plate can push the second screw rod to move downward, and then the pressing plate can fix and clamp the strip. The second buckle at the end of the top plate can be clamped on the first buckle to maintain the stability of the top plate. The moving pneumatic traction mechanism continues to move, and then the limiting plate can contact with the picking plate, so that the picking plate can lift the limiting plate, and then the second screw rod rises, so that the first contact block on the second screw rod can push the top plate up through the first contact block, so that the first buckle and the second buckle are disengaged. At this time, the top plate resets under the action of the elastic plate and the second spring, and then the pressing plate disengages from pressing the strip, which is convenient for removing the PET grille;

[0022] The PET strip is pulled into place, avoiding defects such as belt running and improper belt feeding; the traction holes with adjustable width can ensure the accuracy of the belt feeding position, ensure the consistency of the position of each strip, avoid the defect of transverse strip welding deviation, ensure the uniformity of the mesh holes, and improve the product quality; automatic strip traction can be realized, and multiple strips can be pulled simultaneously; the strip can be clamped during welding and remains clamped until the strip cools after leaving the welding position, which can avoid the defect of thermal shrinkage of the strip during welding and causing the grille to deform, and is especially beneficial for materials sensitive to problems such as PET welded grilles.

[0023] The position of the PET strip is detected by the first sensor and the second sensor, and after detection, it is welded by the welding mechanism. The welding mechanism is adjusted up and down by the servo electric cylinder, and then welded by the welding head. After welding, the PET strip is cut by the cutting mechanism, and the cutting mechanism is moved by the second servo motor and drives the cutting knife to operate, facilitating the cutting of the PET strip during the movement process.

[0041] As Figure 1-8 shown, the fully automatic tape feeding device of the welding equipment includes a mounting frame 1 and a first servo motor 207, and a conveying assembly 2 is provided inside the mounting frame 1;

[0042] Embodiment 1:

[0043] The conveying assembly 2 includes two lead screws 203 provided inside the mounting frame 1. One end of each of the two lead screws 203 is fixedly provided with a fixed pneumatic traction mechanism 201, and the other ends of the two lead screws 203 are threadedly connected to a moving pneumatic traction mechanism 202. The end portions of the two lead screws 203 are respectively key-connected to transmission wheels 204. The end portion of one of the lead screws 203 is in transmission connection with the output end of the first servo motor 207, and the two transmission wheels 204 are in transmission connection through a transmission belt 206;

[0044] A threading hole 220 is formed in the middle of the fixed pneumatic traction mechanism 201 and the moving pneumatic traction mechanism 202. Air cavities 214 are formed on the upper and lower sides of the threading hole 220 of the fixed pneumatic traction mechanism 201 and the moving pneumatic traction mechanism 202. Air jet holes 215 are formed on the inner sides of the air cavities 214. The two sides of the threading hole 220 are connected with adjusting blocks 213 through first screws 212;

[0045] A pressing plate 217 is provided inside the threading hole 220 of the moving pneumatic traction mechanism 202. A second screw 216 passing through the moving pneumatic traction mechanism 202 is movably connected to the pressing plate 217. A first spring 218 is sleeved on the upper end of the second screw 216. A limiting plate 219 is fixedly provided at the top end of the second screw 216. The two ends of the first spring 218 are respectively fixed on the upper end surface of the moving pneumatic traction mechanism 202 and the lower surface of the limiting plate 219. An air inlet nozzle 211 is formed on one side of the upper and lower air cavities 214. The air inlet nozzle 211 is used to connect an external air pump, and a control valve is connected to the air inlet nozzle 211. A pressing wheel 205 is fixedly installed on one side of the mounting frame 1, and the pressing wheel 205 is attached above the transmission belt 206;

[0046] Both sides of the mounting bracket 1 are provided with conveying holes 5, and the conveying holes 5 are correspondingly arranged with the threading holes 220 on the fixed pneumatic traction mechanism 201 and the moving pneumatic traction mechanism 202. One side of the mounting bracket 1 is welded with a mounting plate 208, and the first servo motor 207 is fixedly installed on the mounting plate 208. Four support legs 7 are respectively welded at the four corners of the lower end surface of the mounting bracket 1;

[0047] A first sensor 209 is fixedly arranged at the lower part of one side of the fixed pneumatic traction mechanism 201, and a second sensor 210 is fixedly arranged at the lower part of one side of the moving pneumatic traction mechanism 202. Both the first sensor 209 and the second sensor 210 are located at the middle lower part of the threading hole 220;

[0048] For the above-mentioned fully automatic tape feeding device of the welding equipment, through the conveying assembly 2, the transportation of the PET strip is realized. That is, the PET strip first passes through the conveying hole 5, so that the end of the PET strip is inside the fixed pneumatic traction mechanism 201. Then, an external air pump is started to fill high-pressure gas into the air cavity 214 in the fixed pneumatic traction mechanism 201. Then, the upper and lower air cavities 214 eject high-pressure gas on the PET strip through the air jet holes 215. Through the relatively ejected high-pressure gas, the PET strip is clamped, and the PET strip can be stably maintained at the center of the threading hole 220. Then, the first servo motor 207 is started. The first servo motor 207 drives the two lead screws 203 to rotate by driving the transmission runner 204, the transmission belt 206 and the pressing wheel 205. Furthermore, the two lead screws 203 can drive the moving pneumatic traction mechanism 202 to move, so that the moving pneumatic traction mechanism 202 can approach the fixed pneumatic traction mechanism 201 to clamp the end of the PET strip. And in order to maintain the stability of the clamping, the PET strip is clamped by the pressing plate 217 and the first spring 218 to facilitate maintaining the stability of the PET strip. Then, the moving pneumatic traction mechanism 202 is driven by the lead screw 203 to reset, realizing the transportation of the PET strip. Then, the size of the PET strip is detected by the first sensor 209 and the second sensor 210;

[0049] And inside the threading holes 220 of the fixed pneumatic traction mechanism 201 and the moving pneumatic traction mechanism 202, an adjusting block 213 is connected by a first screw 212. That is, the position of the adjusting block 213 is adjusted by the first screw 212 to facilitate the adjustment of the size of the threading hole 220, so as to realize the transportation of PET strips of different sizes, ensure the accuracy of the tape feeding position, ensure that the position of each strip is consistent, avoid the defect of the transverse strip being welded offset, ensure the uniformity of the mesh holes, and improve the product quality.

[0050] Embodiment Two:

[0051] The mounting bracket is provided with a pick - up plate 221 on one side of the mobile pneumatic traction mechanism. An elastic plate 222 is fixedly arranged on one side of the mobile pneumatic traction mechanism. A moving hole 223 is formed on one side of the mobile pneumatic traction mechanism. An adjusting cavity 224 is formed inside the moving hole 223 of the mobile pneumatic traction mechanism. A first buckle 225 is fixedly arranged on one end wall of the adjusting cavity 224. A first contact block 232 is fixedly arranged on one side of the second screw 216. A top plate 226 is fixedly arranged inside the elastic plate 222. A second contact block 228 is fixedly arranged at one end of the top plate 226. A second buckle 229 is fixedly arranged at the end of the top plate 226. A second spring 231 is fixedly arranged between the elastic plate 222 and the mobile pneumatic traction mechanism. A T - shaped slideway 230 is formed on one side of the top plate 226. A positioning and limiting block 227 is fixedly arranged on one side of the adjusting cavity 224, and one side of the positioning and limiting block 227 is movably connected inside the T - shaped slideway 230;

[0052] It should be noted that, in order to ensure that the pressing plate 217 can stably press and fix the strip for easy traction, when the mobile pneumatic traction mechanism 202 moves and contacts one side of the fixed pneumatic traction mechanism 201, the elastic plate 222 contacts the fixed pneumatic traction mechanism 201, causing the elastic plate 222 to be squeezed. As a result, the top plate 226 can move inside the adjusting cavity 224, and then the top plate 226 can contact and collide with the first contact block 232 on the second screw 216 through the second contact block 232, enabling the top plate 226 to push the second screw 216 downward, so that the pressing plate 217 can fixedly clamp the strip. And when the top plate 226 moves, the second buckle 229 at the end can be engaged with the first buckle 225 to maintain the stability of the top plate 226. Then the mobile pneumatic traction mechanism 202 resets and stops at a position close to the pick - up plate 221. Then the strip is welded by the welding mechanism 4. After the welding process, the first servo - motor 207 is started to drive the mobile pneumatic traction mechanism 202 to move again, so that the limiting plate 219 can contact the pick - up plate 221, causing the pick - up plate 221 to lift the limiting plate 219, and then the second screw 216 rises, enabling the first contact block 232 on the second screw 216 to lift the top plate 226 through the first contact block 232, causing the separation between the first buckle 225 and the second buckle 229. At this time, the top plate 226 resets under the action of the elastic plate 222 and the second spring 231, so that the pressing plate 217 disengages from pressing the strip, facilitating the removal of the PET grille.

[0053] Embodiment Three:

[0055] In another embodiment, after threading the PET strip, the PET strip is welded by the welding mechanism 4, that is, the position of the lifting plate 401 is lowered by the servo electric cylinder 403, so that the welding heads 402 on the lifting plate 401 can approach the PET strip to realize the welding treatment of the PET strip.

[0056] Embodiment Four:

[0058] For another example, after the PET strip is welded, the PET strip is cut by the cutting mechanism 3, that is, the gear 306 is driven to rotate by the second servo motor 303, and the gear 306 is meshed with the rack 301, so that the housing 302 and the cutting knife 312 can move inside the mounting frame 1.
