Description

Technical Field

[0001] The utility model relates to the field of cardboard processing, and particularly relates to a cardboard turning manipulator for spraying PU. Background Art

[0002] PU, whose full name is Polyurethane and is called polyurethane in Chinese, is a polymer material formed by the polycondensation reaction of polyols and polyisocyanates. Due to the excellent properties of polyurethane, it is widely used in many fields such as textiles, construction, aviation, ships, transportation, medicine, electronics, etc. Spraying polyurethane on the surface of cardboard can make polyurethane board. When producing polyurethane board, it is necessary to spray polyurethane on both sides of the cardboard. Therefore, a cardboard turning manipulator is needed to turn the cardboard over.

[0003] The publication number CN221135906U discloses a manipulator for turning over cardboard processing materials, including a fixing plate and a mounting plate. A pressing mechanism is arranged on one side of the fixing plate. The pressing mechanism includes a bottom plate. The bottom of the fixing plate is fixedly connected with the bottom plate. A chute is opened at the top of the bottom plate. A slide rail is fixedly connected inside the chute. The outer wall of the slide rail is movably connected with a slider.

[0004] The above device uses a moving fixture to clamp the cardboard. After the cardboard is clamped, the motor drives the fixture to rotate to realize the turning over of the cardboard. However, the cardboard itself has a low hardness, and the cardboard will be subject to a large resistance during the rotation process. When the fixture drives a long cardboard to turn over, it is easy to bend the cardboard. Therefore, a cardboard turning manipulator for spraying PU is proposed. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a cardboard turning manipulator for spraying PU, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A cardboard turning manipulator for spraying PU, comprising an equipment base, on which an equipment housing is fixedly installed. Inside the equipment housing, there is a first conveyor belt and a second conveyor belt. At the middle position of the equipment housing, there is a turning component, which includes a positioning plate fixed inside the equipment housing. On the positioning plate, a servo motor is fixedly installed. At the output end of the servo motor, a driving shaft is fixedly installed. On the driving shaft, a clamping frame is fixedly installed. At both the upper and lower ends of the clamping frame, movable rollers are movably installed. At one side edge of the clamping frame, a pressing mechanism is fixedly installed. The pressing mechanism includes a mechanism housing fixed on the clamping frame. At the upper end of the mechanism housing, an electromagnet is fixedly installed. At the lower end of the mechanism housing, a pressing rod is movably installed. At the lower end of the pressing rod, a pressing block is fixedly installed. The pressing rod will drive the pressing rod to move up and down.

[0008] Furthermore, the turning component further includes a bearing fixed on the positioning plate, and an access through-hole is provided at one side edge of the clamping frame.

[0009] Furthermore, bolts are provided at the four corners of the positioning plate, and the positioning plate is fixed inside the equipment housing through the bolts.

[0010] Furthermore, the driving shaft is movably installed on the positioning plate through a bearing, the clamping frame is movably installed inside the equipment housing through the driving shaft. At both the upper and lower ends of the clamping frame, movable holes are provided. The movable rollers are movably installed on the clamping frame through the movable holes. The servo motor can drive the driving shaft to rotate, and after the driving shaft rotates, it will drive the clamping frame to rotate.

[0011] Furthermore, the pressing mechanism further includes a pressing spring arranged inside the mechanism housing. At the upper end of the pressing rod, an iron spring seat is fixedly installed. At the lower surface of the pressing block, a rubber pad is fixedly installed. The pressing spring will provide elastic force to the iron spring seat, making it tend to move downward.

[0012] Furthermore, a movable hole is provided at the lower end of the mechanism housing, and the pressing rod is movably installed at the lower end of the mechanism housing through the movable hole.

[0013] Furthermore, the pressing block is movably installed at the lower end of the mechanism housing through the pressing rod. One end of the pressing spring is connected to the upper end of the mechanism housing, and the other end of the pressing spring is connected to the iron spring seat. The pressing rod passes through the clamping frame through the access through-hole. The electromagnet can adsorb the iron spring seat, and when the iron spring seat is adsorbed by the electromagnet, it will drive the pressing rod to move upward.

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] The cardboard can be conveyed into the clamping frame body. The servo motor can drive the drive shaft to rotate. After the drive shaft rotates, it will drive the clamping frame body to rotate, causing the cardboard in the clamping frame body to be turned over. The turned-over cardboard will slide along the movable roller onto the second conveyor belt, facilitating the conveyance of the cardboard into the spraying machine for spraying on the other side. Moreover, during the turning-over process, the cardboard always remains within the clamping frame body, which can reduce the occurrence of cardboard bending accidents.

[0016] After the cardboard is conveyed into the clamping frame body, the magnetic force of the electromagnet can be controlled to slowly decrease. After the magnetic force of the electromagnet slowly decreases, the compression spring will drive the pressing block on the pressing rod to slowly move downward, thereby pressing the cardboard tightly within the clamping frame body. The slow downward movement of the pressing block can reduce the damage to the cardboard. At the same time, the iron spring seat can be adsorbed by the electromagnet. After the iron spring seat is adsorbed by the electromagnet, the pressing rod will drive the pressing block to reset, thereby releasing the cardboard within the clamping frame body.

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further elaborated below in conjunction with specific embodiments.

[0023] As Figure 1 Figure 2As shown in the figure, a cardboard turning manipulator for spraying PU includes an equipment base 1, on which an equipment housing 2 is fixedly installed. Inside the equipment housing 2, there is a first conveyor belt 3 and a second conveyor belt 4. At the middle position of the equipment housing 2, there is a turning component 5. The turning component 5 includes a positioning plate 503 fixed inside the equipment housing 2. On the positioning plate 503, a servo motor 507 is fixedly installed. At the output end of the servo motor 507, a driving shaft 505 is fixedly installed. On the driving shaft 505, a clamping frame 501 is fixedly installed. At the upper and lower ends of the clamping frame 501, movable rollers 502 are movably installed. At one side edge of the clamping frame 501, a pressing mechanism 6 is fixedly installed. The pressing mechanism 6 can fix the cardboard on the turning component 5. After the cardboard is fixed on the turning component 5, the clamping frame 501 on the turning component 5 can drive the cardboard to turn quickly.

[0024] As Figure 3 shown in the figure, at the middle position of the equipment housing 2, there is a turning component 5. The turning component 5 includes a positioning plate 503 fixed inside the equipment housing 2. On the positioning plate 503, a servo motor 507 is fixedly installed. At the output end of the servo motor 507, a driving shaft 505 is fixedly installed. On the driving shaft 505, a clamping frame 501 is fixedly installed. At the upper and lower ends of the clamping frame 501, movable rollers 502 are movably installed. The turning component 5 also includes a bearing 506 fixed on the positioning plate 503. At one side edge of the clamping frame 501, an access through-hole 504 is provided.

[0025] Specifically, the cardboard can be conveyed into the clamping frame 501. The servo motor 507 can drive the driving shaft 505 to rotate. After the driving shaft 505 rotates, it will drive the clamping frame 501 to rotate, so that the cardboard in the clamping frame 501 turns over. The turned-over cardboard will slide along the movable roller 502 onto the second conveyor belt 4, which is convenient for conveying the cardboard into the spraying machine for spraying the other side. And during the turning process, the cardboard always remains in the clamping frame 501, which can reduce the occurrence of accidents of cardboard bending.

[0026] As Figure 4 shown in the figure, the pressing mechanism 6 includes a mechanism housing 601 fixed on the clamping frame 501. At the upper end of the mechanism housing 601, an electromagnet 602 is fixedly installed. At the lower end of the mechanism housing 601, a pressing rod 604 is movably installed. At the lower end of the pressing rod 604, a pressing block 605 is fixedly installed. The pressing mechanism 6 also includes a pressing spring 603 arranged inside the mechanism housing 601. At the upper end of the pressing rod 604, an iron spring seat 607 is fixedly installed. At the lower surface of the pressing block 605, a rubber pad 606 is fixedly installed.

[0027] Specifically, after the cardboard is conveyed into the clamping frame body 501, the magnetic force of the electromagnet 602 can be controlled to slowly decrease. After the magnetic force of the electromagnet 602 slowly decreases, the compression spring 603 will drive the pressing block 605 on the downward pressing rod 604 to slowly move downward, thereby pressing the cardboard tightly in the clamping frame body 501. The slow downward movement of the pressing block 605 can reduce the damage to the cardboard. At the same time, the iron spring seat 607 can be adsorbed by the electromagnet 602. After the iron spring seat 607 is adsorbed by the electromagnet 602, the downward pressing rod 604 will drive the pressing block 605 to reset, thereby loosening the cardboard in the clamping frame body 501.

[0028] It should be noted that the present utility model is a cardboard turning manipulator during the spraying of PU. In actual use, first, the cardboard is conveyed into the clamping frame body 501 by the first conveyor belt 3. After the cardboard is conveyed into the clamping frame body 501, the magnetic force of the electromagnet 602 can be controlled to slowly decrease. Since one end of the compression spring 603 is connected to the upper end of the mechanism housing 601 and the other end of the compression spring 603 is connected to the iron spring seat 607, after the magnetic force of the electromagnet 602 slowly decreases, the compression spring 603 will drive the pressing block 605 on the downward pressing rod 604 to slowly move downward, thereby pressing the cardboard tightly in the clamping frame body 501. After the cardboard is pressed tightly in the clamping frame body 501, the servo motor 507 can be started. Since the drive shaft 505 is movably installed on the positioning plate 503 through the bearing 506 and the clamping frame body 501 is movably installed in the equipment housing 2 through the drive shaft 505, after the servo motor 507 is started, it will drive the drive shaft 505 to rotate. After the drive shaft 505 rotates, it will drive the clamping frame body 501 to rotate, turning the cardboard over. When the pressing mechanism 6 is inclined downward towards the second conveyor belt 4, the servo motor 507 can be turned off. Then, the electromagnet 602 can be started. After the electromagnet 602 is started, the pressing block 605 will reset, loosening the cardboard in the clamping frame body 501. At this time, the turned-over cardboard will slide along the movable roller 502 onto the second conveyor belt 4, facilitating the conveyance of the cardboard into the spraying machine for spraying the other side.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
