Description

Technical Field

[0001] This invention relates to the field of PVC glue spraying machine technology, specifically a PVC glue spraying conveyor. Background Technology

[0002] PVC coating is a common surface treatment process. It mainly involves mixing PVC resin with plasticizers, stabilizers, pigments and other additives to make a coating. The coating is then evenly applied to the surface of the substrate. After drying and curing, a coating with a certain thickness and performance is formed to achieve the purpose of protection, decoration or to impart specific functions.

[0003] Currently, PVC coating machines have certain shortcomings in actual use. The workpiece to be coated needs to be pre-installed on a designated fixture, and the fixture and workpiece are delivered to the coating area via the machine tool slide rail. However, the delivery coating method is easily restricted and interfered with by the fixture, especially the coating process of hollow workpieces. The structure of hollow workpieces is different from that of conventional workpieces, and their surface is more complex, so the coating will be interfered with. In severe cases, it will cause uneven coating thickness or other defects on the surface of the hollow workpiece.

[0004] In view of this, a PVC glue spraying conveyor was designed to solve the above problems. Summary of the Invention

A first washer 330 is provided on the outside of the first threaded sleeve 340. The two ends of the first pad 330 are movably connected to two symmetrically distributed first cantilever 320; The other end of the first cantilever 320 is movably connected to the clamping plate 230.

[0032] Preferably, two sets of clips 240 located at the bottom of the main support plate 210 and the auxiliary support plate 220 are used to provide effective limiting constraints for the limiting plate 310, and the two ends of the limiting plate 310 are provided with anti-detachment plates.

At this time, an adjacent main support plate 210 and a secondary support plate 220 will be compressed and push the two sets of air-conditioning angle mechanisms 500 to extend at equal intervals.

[0033] Example 4: Combination Figure 4 and Figure 6 As shown, based on Embodiment 1, the drive mechanism 400 includes a support plate 410 installed at the bottom of two main support plates 210, a housing 420 installed in the middle of the support plate 410, and a motor 430 installed inside the housing 420. The outer end of the internal drive shaft of the motor 430 is equipped with a drive end head, and the drive end head is connected to the track 440 for transmission.

[0035] Example 5: Combination Figures 7 to 10As shown, in the above embodiment, the workpiece clamping mechanism 600 includes two outer frames 610 mounted on two sliding plates 520, a base 620 mounted inside the two outer frames 610, and a second lead screw 630 movably mounted in the middle hole of the outer frame 610. A second washer 640 is provided on the threaded section of the second lead screw 630, and a second threaded sleeve 650 is provided on the outside of the second washer 640. The top and bottom ends of the second threaded sleeve 650 are movably mounted with two symmetrically distributed second cantilevers 660, and the other end of the second cantilevers 660 is mounted with a crossbar 670. The other end of the crossbar 670 is installed inside the tension arm 560.

[0036] Preferably, the base 620 is fixed to the middle of the two outer frames 610 by welding, and the end of the drive shaft 450 away from the track 440 is installed inside one of the bases 620 by welding. When one or two of the second lead screws 630 are rotated, the two adjacent sets of second cantilevers 660 can work with the two sets of crossbars 670 to apply different lateral thrusts to the four evenly distributed tension arms 560. Finally, the four steel cables 590 after the tension of the four longitudinal tension arms 560 is adjusted can apply different degrees of compressive force to the inner wall of the hollowed-out workpiece. At this time, the workpiece can be clamped and fixed according to the selected inclination angle.

[0037] The working principle and usage process of this invention are as follows: According to the size of the workpiece, the steel cable 590 is installed in the designated holes of the two tension arms 560 using two wire harness pins 580. Then, the rotating wheel 270 at the outer end of the two second lead screws 630 is adjusted to rotate counterclockwise. At this time, the second pad 640 and the second screw sleeve 650 will move outward along the second lead screw 630. The two second cantilever arms 660, which are movably installed at the top and bottom of the second screw sleeve 650, will be pressed and drive the two crossbars 670 to extend at equal intervals. The two tension arms 560 installed on the two crossbars 670 will be pressed and flipped to the side until the four evenly distributed steel cables 590 are located inside the workpiece. Under the relative flipping of the four tension arms 560, the workpiece is pressed outward. After the workpiece is tightened by four steel cables 590 from the inside, according to the height requirements of the workpiece at both ends, two sets of retaining angle mechanisms 500 are used to tighten the two ends of the workpiece at the same horizontal height or at an angle. Once the workpiece is tightened by the two sets of retaining angle mechanisms 500, the auxiliary mechanism 200 can be controlled to move effectively laterally along the inner side of the bearing mechanism 100. During the overall lateral movement of the auxiliary mechanism 200, the two sets of retaining angle mechanisms 500 installed on the auxiliary mechanism 200 can deliver the tightened workpiece to the nozzle of the glue spraying machine. Finally, the workpiece can be effectively and evenly sprayed by the glue sprayer with the maximum exposed area. Workpieces tightened on the same horizontal plane can be coated with glue of uniform thickness during this period, while workpieces tightened at an angle can be coated with glue of varying thickness. When the length of the workpiece to be processed is short or long, the first lead screw 350 can be adjusted to rotate until the first screw sleeve 340 and the first pad 330 rise and fall stably along the first lead screw 350. Finally, the two first cantilever 320s movably installed at both ends of the first pad 330 can apply traction force to the two clamping plates 230. Finally, the main support plate 210 and the auxiliary support plate 220 can be extended moderately along the gap between the top track 120 and the bottom track 130. At this time, the two adjacent main support plates 210 and the two auxiliary support plates 220 can expand to adapt to workpieces of different lengths. After the workpiece is evenly coated with adhesive, the motor 430 can be started. At this time, the transmission shaft inside the motor 430 will drive the track 440, and the other end of the track 440 will drive the drive shaft 450. A set of stabilizing angle mechanism 500 installed at the inner end of the drive shaft 450 can cooperate with another set of stabilizing angle mechanism 500 to rotate the tightened workpiece in a circular motion. At this time, the bottom surface of the tightened workpiece can be flipped. After the workpiece is flipped, its upward bottom surface can be coated with adhesive again.
