Description

Technical Field

[0001] This invention belongs to the field of pressure vessel liner welding technology, and particularly relates to an integrated module for infrared heating welding of pipes. Background Technology

[0002] The most crucial manufacturing technology for pressure vessels is the production of the inner liner, and the welding of the inner liner is the most critical technology in the inner liner manufacturing process.

[0003] Traditional plastic pipe welding equipment uses hot plate heating. When the hot plate is pulled out, it can cause the product to stick or string, affecting the welding quality.

[0004] Therefore, the welding workstation of this invention adopts a non-contact infrared heating process to ensure that the product does not stick or produce wires. The welding component is an infrared heating module. Under the action of infrared rays, the weld seam of adjacent pipes to be welded can be rapidly condensed. After pressing and cooling, they are bonded together and can achieve extremely high welding strength without producing phenomena such as sticking or wires.

[0005] However, to improve welding quality, the pipes on both sides of the weld need to be leveled before welding, and the weld needs to be cut and ground after welding. Furthermore, different models of infrared heating welding molds are required when welding different products, meaning the welding assembly faces the problem of needing to change the infrared heating welding molds. To address this, traditional quick-change tooling for infrared heating welding molds is used. Most infrared heating welding molds are detachably mounted to the quick-change tooling using multiple bolts and other threaded fasteners. While this ensures the secure installation of the infrared heating welding molds, its assembly and disassembly are cumbersome, affecting production efficiency.

[0006] Therefore, how to provide an integrated module for pipe infrared heating welding that can integrate the three functions of leveling, cutting and grinding, and can realize the rapid replacement of infrared heating welding molds, has become a technical problem that urgently needs to be solved in this field.

[0054] (1) The infrared heating welding cutting device of the present invention integrates infrared heating welding mold and cutting module, has a simple structure, realizes multiple functions, and is conducive to simplifying the overall structure of the welding workstation and making full use of space.

[0055] (2) The cutting module integrates three functions: leveling, cutting and grinding. It has a simple structure and realizes the multi-functionality of the cutting module, which further facilitates the simplification of the overall structure of the welding workstation and the full utilization of space.

[0056] (3) The forward and backward movement of the movable blade and the grinding assembly is driven by a drive unit with only one power source, and the movable blade and the grinding assembly move in opposite directions. Thus, one of the movable blade and the grinding assembly works in the front while the other waits in the rear. The drive structure for the forward and backward movement of the movable blade and the grinding assembly is simple, requiring only one power source to drive both, thus saving energy.

[0057] (4) By combining the fast moving unit and the fast moving auxiliary unit, and by setting limit units and locking units at the front and rear ends of the quick-change tooling, the assembly and disassembly of the infrared heating welding mold are simple and efficient under the premise of ensuring the firmness of the infrared heating welding mold installation, which greatly improves the production efficiency of the pipe welding device.

[0058] (5) The upper guide wheel assembly, lower guide wheel assembly, and horizontal guide wheel assembly on the inner end face of the vertical mounting plate constitute the rapid movement auxiliary units on both sides of the quick-change tooling; the mating parts extending outward from the left and right ends of the quick-fit plate constitute the rapid movement units on both sides of the infrared heating welding mold. Thus, under the combined action of the rapid movement unit and the rapid movement auxiliary unit, the infrared heating welding mold can be quickly pulled out from front to back and quickly pushed in from back to front.

[0059] (6) The upper guide wheel group, the lower guide wheel group and the horizontal guide wheel group are surrounded on the outside of the mating part and are all in rolling contact with the mating part. This can ensure the rapid extraction and insertion of the infrared heating welding mold, as well as the stability and consistency of the movement of the infrared heating welding mold.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0084] It should be noted that the terms "upper," "lower," "inner," "outer," and "middle," etc., used in the specification, claims, and accompanying drawings of this invention indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings. These terms are primarily for the purpose of better describing the invention and its embodiments, and are not intended to limit the indicated devices, elements, or components to having a specific orientation, or to be constructed and operated in a specific orientation. Furthermore, some of the above terms may be used to indicate other meanings besides orientation or positional relationships; for example, the term "upper" may in some cases indicate a dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this invention according to the specific circumstances. In addition, the term "multiple" should mean two or more.

[0085] like Figure 1-22 As shown, this embodiment provides an integrated module for pipe infrared heating welding as a subsystem of welding workstation 100. Welding workstation 100 includes a pipe 2000 to be welded, which is fixed by a clamping device 1000. A welding assembly is provided on one side of the pipe 2000 to be welded, so as to weld the weld seam of adjacent pipes.

[0086] It should be noted that the welding workstation 100 of this embodiment is particularly suitable for welding plastic inner liner materials, that is, the two ends of the plastic pipe 2000 to be welded are respectively arranged with closed ends (not shown), and the welding assembly welds the weld between the pipe 2000 to be welded and its adjacent closed ends. However, the object processed by the welding assembly and the processing technology used do not constitute a limitation on this embodiment. All seam welding involving plastic tubular materials falls within the scope of this embodiment.

[0087] Understandably, traditional plastic pipe welding equipment uses hot plate heating, which can cause material sticking and stringing when the hot plate is pulled out, affecting the welding quality.

[0088] Therefore, the welding workstation 100 in this embodiment adopts a non-contact infrared heating process to ensure that the product does not stick or produce wires. In other words, the welding component is a pipe infrared heating welding integrated module 3000. Under the action of infrared rays, the weld seams of adjacent pipes 2000 to be welded can be rapidly condensed. After pressing and cooling, they are bonded together and can achieve extremely high welding strength without producing phenomena such as sticking or wires.

[0089] In other words, refer to the appendix for key information. Figure 2-20 The welding assembly in this embodiment is an infrared heating welding and cutting device, including a device base 3001 and an infrared heating welding mold 3300 and a cutting module 3400 slidably mounted on the upper end of the device base 3001. The sliding direction of the infrared heating welding mold 3300 and the cutting module 3400 is perpendicular to the axial direction of the pipe 2000 to be welded. The device base 3001 is slidably mounted on the frame assembly 5000 of the welding workstation 100, and the sliding direction of the device base 3001 is parallel to the axial direction of the pipe 2000 to be welded.

[0090] It is worth noting that the infrared heating welding cutting device of this embodiment integrates the infrared heating welding mold 3300 and the cutting module 3400. It has a simple structure, realizes multiple functions, and is conducive to simplifying the overall structure of the welding workstation 100 and making full use of space.

[0091] Understandably, the infrared heating welding mold 3300 and the cutting module 3400 installed on the device base 3001 can slide along the axial direction of the pipe to be welded 2000 with the device base 3001 to match the position of the weld seam of the pipe to be welded 2000; the infrared heating welding mold 3300 slides back and forth in a direction perpendicular to the axial direction of the pipe to be welded 2000, thereby causing the infrared heating welding mold 3300 to slide toward or away from the pipe to be welded 2000, so as to adjust the heating distance of the infrared heating welding mold 3300 to the pipe to be welded 2000, and to facilitate the rapid removal of the infrared heating welding mold 3300 after the weld seam is heated; the cutting module 3400 slides back and forth in a direction perpendicular to the axial direction of the pipe to be welded 2000, thereby causing the infrared heating welding mold 3300 to slide toward or away from the pipe to be welded 2000, so as to adjust the cutting action distance of the cutting module 3400 to the pipe to be welded 2000.

[0092] Specifically, a base slider 3002 is provided at the lower end of the device base 3001, and the frame assembly 5000 includes a ground rail that matches the base slider 3002, so that the device base 3001 can slide along the axial direction of the pipe 2000 to be welded; a first base slider 3003 and a second base slider 3004 are also fixedly provided above the device base 3001. The infrared heating welding mold 3300 is detachably mounted on the infrared heating module mounting plate 3100 through a quick-change tooling 3200, and the infrared heating module mounting plate... The lower end of 3100 is equipped with a first slide rail 3110 that matches the first base slider 3003, so that the infrared heating welding mold 3300 can slide back and forth in a direction perpendicular to the axial direction of the pipe 2000 to be welded; the cutting module 3400 is disposed on the upper end surface of the cutting module mounting plate 3410, and the lower end of the cutting module mounting plate 3410 is equipped with a second slide rail 3411 that matches the second base slider 3004, so that the cutting module 3400 can slide back and forth in a direction perpendicular to the axial direction of the pipe 2000 to be welded.

[0093] It is worth noting that, in order to improve welding quality, the welding workstation 100 of this embodiment levels the pipes 2000 to be welded on both sides of the weld before welding, and cuts and grinds the weld after welding. The cutting module 3400 integrates the three functions of leveling, cutting, and grinding, has a simple structure, and achieves multi-functionality, further simplifying the overall structure of the welding workstation 100 and making full use of space.

[0094] The cutting module 3400 of this embodiment includes a mounting frame 3420 disposed on the cutting module mounting plate 3410 and a blade assembly 3430 mounted above the mounting frame 3420, so as to perform pre-welding leveling and post-welding cutting on the pipe 2000 to be welded by the blade assembly 3430; the cutting module 3400 also includes a grinding assembly 3440 installed in the mounting frame 3420, so as to perform post-cutting grinding on the pipe 2000 to be welded by the grinding assembly 3440.

[0095] The blade assembly 3430 includes a fixed blade 3431 and a movable blade 3432. The sliding direction of the movable blade 3432 is perpendicular to the axial direction of the pipe 2000 to be welded. Thus, when the movable blade 3432 and the fixed blade 3431 are flush with the pipe 2000 to be welded, the fixed blade 3431 and the movable blade 3432 respectively level the pipe 2000 to be welded on both sides of the weld. When the movable blade 3432 protrudes beyond the fixed blade 3431 relative to the pipe 2000 to be welded, the movable blade 3432 cuts the weld area alone.

[0096] The mounting frame 3420 of this embodiment includes a pair of side plates 3421 spaced apart on the upper surface of the cutting module mounting plate 3410. A front plate 3422 is provided at the front end of the pair of side plates 3421, and the front plate 3422 has a through opening 3423 so that the grinding wheel belt 3441 in the grinding assembly 3440 inside the mounting frame 3420 passes through the through opening 3423 and can act on the pipe 2000 to be welded. A top plate 3424 is provided at the upper end of the pair of side plates 3421, and a fixed blade 3431 and a movable blade 3432 are mounted on the upper surface of the top plate 3424.

[0097] Specifically, a fixed blade holder 3433 is fixedly mounted on the upper surface of the top plate 3424, and a fixed blade 3431 is fixedly mounted on the fixed blade holder 3433. A movable blade holder 3434 is also slidably mounted on the upper surface of the top plate 3424, and a movable blade 3432 is fixedly mounted on the movable blade holder 3434, allowing the movable blade 3432 to slide relative to the top plate 3424. Preferably, a sliding rail 3435 is fixedly provided on the inner side of the movable blade holder 3434, and the sliding rail 3435 is also slidably disposed on the upper surface of the top plate 3424. Fixed rails 3427 matching the sliding rail 3435 are fixedly provided on both sides of the top plate 3424. Thus, the drive assembly acts on the movable blade holder 3434 to drive the movable blade 3432 to slide back and forth.

[0098] The grinding assembly 3440 of this embodiment includes a base vertical plate 3442 disposed within a mounting frame 3420, serving as the mounting base for the grinding assembly 3440. A grinding wheel belt 3441 and various grinding wheels are mounted on the base vertical plate 3442. Specifically, a drive wheel 3443 and a driven wheel 3444 are rotatably disposed on one side of the base vertical plate 3442, and the grinding wheel belt 3441 is arranged around the outside of the drive wheel 3443 and the driven wheel 3444. Thus, the grinding power unit 3450 drives the drive wheel 3443 to rotate, thereby driving the grinding wheel belt 3441 to move, thereby grinding the weld seam.

[0099] As the power input for the grinding assembly 3440, the grinding power unit 3450 includes a grinding motor 3451 disposed on the other side of the base vertical plate 3442. A bearing seat 3452 is fixedly disposed inside the base vertical plate 3442. A rotating shaft 3453 is rotatably mounted inside the bearing seat 3452 and extends out from both sides of the base vertical plate 3442. A drive wheel 3443 is fixedly mounted on one end of the rotating shaft 3453, and a driven gear 3454 is fixedly mounted on the other end of the rotating shaft 3453. A drive gear 3455 is fixedly disposed at the output end of the grinding motor 3451, and the drive gear 3455 and the driven gear 3454 are meshed together.

[0100] As a preferred embodiment of the grinding assembly 3440, a tensioning mechanism 3460 is also provided on one side of the base vertical plate 3442 to enhance the tension of the grinding wheel belt 3441. Specifically, the tensioning mechanism 3460 includes a swing arm 3461 rotatably mounted on one side of the base vertical plate 3442, and a tensioning wheel 3463 is provided at one end of the swing arm 3461 away from its swing point 3462. The grinding wheel belt 3441 is arranged around the outside of the driving wheel 3443, the driven wheel 3444, and the tensioning wheel 3463. It is understood that a tension spring (not shown) is provided between the base vertical plate 3442 and the swing arm 3461.

[0101] In this embodiment, the grinding assembly 3440 can move back and forth relative to the mounting frame 3420. When the grinding assembly 3440 needs to work, the grinding wheel belt 3441 in the grinding assembly 3440 inside the mounting frame 3420 passes through the through port 3423 and acts on the pipe 2000 to be welded. When the grinding assembly 3440 does not need to work, the grinding wheel belt 3441 in the grinding assembly 3440 retracts into the mounting frame 3420.

[0102] The forward and backward movement of the movable blade 3432 and the grinding assembly 3440 is driven by a drive unit 3470 with only one power source. The movable blade 3432 and the grinding assembly 3440 move in opposite directions, meaning that one of them operates in the front while the other waits in the rear. The drive structure for the forward and backward movement of the movable blade 3432 and the grinding assembly 3440 is simple, requiring only one power source to drive both, thus saving energy.

[0103] Specifically, a vertical plate 3425 is fixedly installed inside the mounting frame 3420, and several slide rails 3426 are fixedly provided on the side of the vertical plate 3425. Several sliders 3445 that match the slide rails 3426 are fixedly provided on the side of the base vertical plate 3442, so that the base vertical plate 3442 can slide back and forth inside the mounting frame 3420, thereby allowing the grinding assembly 3440 installed on the base vertical plate 3442 to slide back and forth inside the mounting frame 3420.

[0104] In other words, the vertical fixed plate 3425 is fixedly installed on the upper surface of the cutting module mounting plate 3410. The vertical fixed plate 3425 is located between a pair of side upright plates 3421 and is arranged parallel to the side upright plates 3421. The mounting base of the grinding assembly 3440 has a base vertical plate 3442 that slides on the side of the vertical fixed plate 3425. Thus, the grinding assembly 3440 as a whole can move relatively back and forth.

[0105] In this embodiment, the single power source of the drive unit 3470 is the cylinder 3471. That is, the planar cam plate 3472 driven by the cylinder 3471 moves up and down relative to each other, thereby driving the movable blade 3432 and the grinding assembly 3440 to move back and forth in opposite directions.

[0106] Specifically, the planar cam plate 3472 has a slanted groove 3473, and a drive shaft (not shown) is movably arranged in the slanted groove 3473. The top plate 3424 has an elongated hole 3436, through which the planar cam plate 3472 passes. The length of the elongated hole 3436 is greater than the width of the planar cam plate 3472 so that the top plate 3424 will not interfere with the forward and backward movement of the planar cam plate 3472. A circular hole 3437 is provided on the side of the elongated hole 3436, and the end of the drive shaft is fixedly arranged inside the circular hole 3437.

[0107] Therefore, when the planar cam plate 3472 driven by the cylinder 3471 moves up and down relative to each other, the relatively fixed drive shaft cooperates with the inclined groove 3473, so that the planar cam plate 3472 moves up and down relative to each other while moving back and forth, so that the moving tool holder 3434, which is relatively fixed to the planar cam plate 3472 in the back and forth direction, moves back and forth with the planar cam plate 3472, thereby driving the moving tool 3432 to slide back and forth.

[0108] Understandably, the cylinder 3471 mounted on the movable tool holder 3434 also moves back and forth with the movable tool holder 3434. Preferably, a vertical slide groove 3438 is fixedly mounted on the upper end of the movable tool holder 3434, and the upper end of the flat cam plate 3472 is vertically slidably mounted within the vertical slide groove 3438. Thus, the cylinder 3471 can drive the flat cam plate 3472 to move up and down relative to each other, and the back and forth movement of the flat cam plate 3472 is transmitted to the movable tool holder 3434 through the vertical slide groove 3438.

[0109] The drive unit 3470 also includes a connecting rod 3474, and a straight groove 3475 is provided on the planar cam plate 3472. One end of the connecting rod 3474 is disposed in the straight groove 3475, and the other end of the connecting rod 3474 is connected to the base vertical plate 3442. Thus, when the planar cam plate 3472 driven by the cylinder 3471 moves up and down and back and forth relative to each other, the straight groove 3475 drives the base vertical plate 3442 to move laterally through the connecting rod 3474, so that the base vertical plate 3442 drives the grinding assembly 3440 to slide back and forth. Preferably, a vertical guide groove 3446 is installed at the lower end of the base vertical plate 3442, and the other end of the connecting rod 3474 is installed in the vertical guide groove 3446 through a pin.

[0110] It should be noted that the cylinder 3471 drives the planar cam plate 3472 to move up and down relative to each other, causing the connecting rod 3474 to swing under the drive of the straight groove 3475 to extend or retract the base vertical plate 3442; at the same time, the drive shaft acts on the inclined groove 3473, causing the planar cam plate 3472 to move back and forth, driving the movable tool holder 3434 and its movable tool 3432 to move in the opposite direction to the base vertical plate 3442. Thus, one of the movable tool 3432 and the grinding assembly 3440 performs work in the front while the other waits in the rear position.

[0111] In this embodiment, a waste chip collection trough 3480 is also provided at the front end of the mounting frame 3420, and a chip discharge pipe 3481 is fixedly provided at the upper end of the cutting module mounting plate 3410, with the inlet end 3482 of the chip discharge pipe 3481 connected to the waste chip collection trough 3480. Thus, waste chips falling from the pipe 2000 to be welded are promptly discharged when the cutting module 3400 is working.

[0112] In this embodiment, the quick-change tooling 3200 is slidably mounted on the upper end of the infrared heating module mounting plate 3100, and the sliding direction of the quick-change tooling 3200 is perpendicular to the axial direction of the pipe 2000 to be welded. The infrared heating welding mold 3300 is detachably mounted on the upper end of the quick-change tooling 3200.

[0113] It is understandable that the quick-change tooling 3200 slides back and forth in a direction perpendicular to the axis of the pipe to be welded 2000, thereby causing the infrared heating welding mold 3300 to slide toward or away from the pipe to be welded 2000, so as to adjust the heating distance of the infrared heating welding mold 3300 to the pipe to be welded 2000.

[0114] Specifically, a third slide rail 3120 is fixedly mounted on the upper surface of the infrared heating module mounting plate 3100, and a tooling slider 3211 is mounted on the lower end of the quick-change tooling 3200. The tooling slider 3211 matches the third slide rail 3120 to enable the quick-change tooling 3200 to reciprocate along a direction perpendicular to the axis of the pipe 2000 to be welded. A power unit (not shown) is also provided at the lower end of the infrared heating module mounting plate 3100, and the actuating end of the power unit is connected to the quick-change tooling 3200, thereby driving the quick-change tooling 3200 to reciprocate along with the infrared heating welding mold 3300.

[0115] Understandably, different models of infrared heating welding molds 3300 are required when welding different products using pipe welding equipment, meaning the welding assembly faces the issue of needing to replace the infrared heating welding mold 3300. To address this, traditional quick-change tooling for infrared heating welding molds 3300 mostly uses multiple bolts and other threaded fasteners to detachably mount the mold onto quick-change tooling 3200. While this ensures the secure mounting of the infrared heating welding mold 3300, its assembly and disassembly are cumbersome, impacting production efficiency.

[0116] To overcome the above-mentioned defects, the quick-change tooling for infrared heating welding mold in this embodiment has quick-moving auxiliary units on both sides of the quick-change tooling 3200, and limit units and locking units at both ends of the quick-change tooling 3200; correspondingly, quick-moving units are provided on both sides of the infrared heating welding mold 3300, and the quick-moving units cooperate with the quick-moving auxiliary units.

[0117] Therefore, when the infrared heating welding mold 3300 needs to be disassembled, simply open the locking unit at the rear end of the quick-change tooling 3200, and then, with the cooperation of the rapid movement unit and the rapid movement auxiliary unit, quickly pull out the infrared heating welding mold 3300 from front to back; when the infrared heating welding mold 3300 needs to be assembled, with the cooperation of the rapid movement unit and the rapid movement auxiliary unit, quickly push the infrared heating welding mold 3300 from back to front until the front end of the infrared heating welding mold 3300 contacts the limiting unit at the front end of the quick-change tooling 3200, and then close the locking unit at the rear end of the quick-change tooling 3200, thus completing the rapid installation of the infrared heating welding mold 3300.

[0118] With this setup, the rapid movement unit and rapid movement auxiliary unit work together, and the limit and locking units are set at the front and rear ends of the quick-change tooling 3200. Under the premise of ensuring the firmness of the infrared heating welding mold 3300 installation, the assembly and disassembly of the infrared heating welding mold 3300 are simple and efficient, which greatly improves the production efficiency of the pipe welding device.

[0119] Specifically, the quick-change tooling 3200 includes a base plate 3210 and vertical mounting plates 3220 fixedly mounted on both sides of the base plate 3210. The two vertical mounting plates 3220 are symmetrically arranged relative to the base plate 3210, and the upper surface of the vertical mounting plates 3220 is higher than the upper surface of the base plate 3210. The quick-movement auxiliary unit, the limiting unit, and the locking unit are all disposed on the base plate 3210 and / or the vertical mounting plates 3220.

[0120] In other words, the base plate 3210 and the vertical mounting plates 3220 on both sides together constitute the U-shaped base mounting frame of the quick-change tooling 3200. The quick-movement auxiliary unit, the limiting unit, and the locking unit are all installed on this base mounting frame. Preferably, the base plate 3210 and the vertical mounting plates 3220 on both sides are connected by the connecting block 3230 at the bottom.

[0121] The inner end face 3221 of the vertical mounting plate 3220 is provided with an upper guide wheel assembly 3240 and a lower guide wheel assembly 3250, with the upper guide wheel assembly 3240 located above the lower guide wheel assembly 3250, and the upper guide wheel assembly 3240 and the lower guide wheel assembly 3250 arranged at intervals; a horizontal guide wheel assembly 3260 is also provided between the upper guide wheel assembly 3240 and the lower guide wheel assembly 3250.

[0122] The rotation axes of the upper guide wheel assembly 3240 and the lower guide wheel assembly 3250 are perpendicular to the inner end face 3221 of the vertical mounting plate 3220. The horizontal guide wheel assembly 3260 is horizontally arranged, and its rotation axis is parallel to the inner end face 3221 of the vertical mounting plate 3220. The infrared heating welding mold 3300 includes an infrared heating mold body 3310 and a quick-fit plate 3320 fixedly disposed at the lower end of the infrared heating mold body 3310. Both ends of the quick-fit plate 3320 extend outward to form mating portions 3330 with the upper guide wheel assembly 3240, the lower guide wheel assembly 3250, and the horizontal guide wheel assembly 3260. The mating portions 3330 maintain contact with the upper guide wheel assembly 3240, the lower guide wheel assembly 3250, and the horizontal guide wheel assembly 3260.

[0123] Therefore, the upper guide wheel assembly 3240, the lower guide wheel assembly 3250, and the horizontal guide wheel assembly 3260 on the inner end face 3221 of the vertical mounting plate 3220 constitute the rapid movement auxiliary units on both sides of the quick-change tooling 3200; the mating parts 3330 extending outward from both ends of the quick-fit plate 3320 constitute the rapid movement units on both sides of the infrared heating welding mold 3300. Thus, under the combined action of the rapid movement units and the rapid movement auxiliary units, the infrared heating welding mold 3300 can be quickly pulled out from front to back and quickly pushed in from back to front.

[0124] In other words, the mating part 3330 has an upper contact surface 3331, a lower contact surface 3332, and an outer contact surface 3333. The upper contact surface 3331 contacts the upper guide wheel assembly 3240 and forms a rolling pair, the lower contact surface 3332 contacts the lower guide wheel assembly 3250 and forms a rolling pair, and the outer contact surface 3333 contacts the horizontal guide wheel assembly 3260 and forms a rolling pair. Thus, the upper guide wheel assembly 3240, the lower guide wheel assembly 3250, and the horizontal guide wheel assembly 3260 surround the outside of the mating part 3330 and are all in rolling contact with the mating part 3330. This ensures both the rapid extraction and insertion of the infrared heating welding mold 3300 and the stability and consistency of the movement of the infrared heating welding mold 3300.

[0125] In this embodiment, the upper guide wheel assembly 3240 includes a plurality of upper guide wheels 3241 arranged in a horizontal array, each upper guide wheel 3241 being rotatably mounted on the inner end face 3221 of the vertical mounting plate 3220 via a horizontal pivot; similarly, the lower guide wheel assembly 3250 includes a plurality of lower guide wheels 3251 arranged in a horizontal array, each lower guide wheel 3251 being rotatably mounted on the inner end face 3221 of the vertical mounting plate 3220 via a horizontal pivot.

[0126] In this embodiment, the horizontal guide wheel assembly 3260 includes a plurality of horizontal guide wheels 3261 arranged in a horizontal array. The vertical mounting plate 3220 has a plurality of horizontally arranged mounting slots 3222, and the number and position of the mounting slots 3222 match the horizontal guide wheels 3261. Each mounting slot 3222 is equipped with a vertical rotating shaft, and each horizontal guide wheel 3261 is rotatably mounted on the corresponding vertical rotating shaft.

[0127] It should be noted that the horizontal guide wheel 3261 protrudes from the inner end face 3221 of the vertical mounting plate 3220, so that the horizontal guide wheel 3261 contacts the outer contact surface 3333. To facilitate easier entry of the mating part 3330 into the space enclosed by the upper guide wheel assembly 3240, the lower guide wheel assembly 3250, and the horizontal guide wheel assembly 3260, the front end of the mating part 3330 is configured as an inclined narrowing section 3334. Preferably, to facilitate the movement of the infrared heating welding mold 3300, handles 3311 are also installed on both sides of the infrared heating mold body 3310 to facilitate applying force to the infrared heating welding mold 3300.

[0128] In this embodiment, the quick-change tooling for the infrared heating welding mold has a limiting protrusion 3270 at its front end, and a limiting groove 3321 at its front end. Thus, when the infrared heating welding mold 3300 needs to be assembled, it is quickly pushed in from back to front until the limiting groove 3321 at the front end of the quick-fit plate 3320 contacts the limiting protrusion 3270. Then, the locking unit at the rear end of the quick-change tooling 3200 is closed, completing the quick installation of the infrared heating welding mold 3300.

[0129] Specifically, the front end of the base plate 3210 is provided with an installation notch 3312, and the limiting protrusion 3270 is fixedly installed in the installation notch 3312. The upper end face of the limiting protrusion 3270 protrudes from the upper end face of the base plate 3210, so that the part of the limiting protrusion 3270 protruding from the base plate 3210 forms an effective limit.

[0130] In this embodiment, the quick-change tooling for infrared heating welding molds has a locking unit 3280 at its rear end. Specifically, a quick-lock mounting base 3223 is fixedly mounted on the outer rear end of the vertical mounting plate 3220, and the quick-locking component 3280 is mounted on the rear end face of the quick-lock mounting base 3223.

[0131] Therefore, when the infrared heating welding mold 3300 needs to be disassembled, the quick-locking component 3280 at the rear end of the vertical mounting plate 3220 can be quickly opened, allowing the infrared heating welding mold 3300 to be quickly pulled out from front to back; when the infrared heating welding mold 3300 needs to be assembled, the infrared heating welding mold 3300 is quickly pushed in from back to front until the limiting groove 3321 at the front end of the quick-fitting plate 3320 contacts the limiting protrusion 3270, and then the quick-locking component 3280 at the rear end of the vertical mounting plate 3220 is quickly closed, thus completing the quick installation of the infrared heating welding mold 3300.

[0132] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
