DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 , Figure 2 As shown, a polyethylene composite pipe processing clamping device includes a base plate 1, a mechanism frame 2 is fixedly connected to the middle of the upper surface of the base plate 1, a rotating mechanism 3 is rotatably connected to the inner side of the mechanism frame 2, a mounting plate 4 is fixedly connected to the inner side of the rotating mechanism 3 near the upper left side, and a conveying mechanism 5 is fixedly connected to the inner side of the rotating mechanism 3.

[0025] It should be noted that a plurality of such devices may be provided to operate synchronously to perform operations such as clamping and conveying the composite pipe, thereby reducing the load on a single device during operation.

[0026] like Figure 2 , Figure 3 As shown, the rotating mechanism 3 includes a first motor 31, the lower side of the first motor 31 is fixedly connected to the upper surface of the substrate 1 near the right side, and the first motor 31 is located on the rear side of the mechanism frame 2, the output end of the first motor 31 is fixedly connected to the first gear 32, and the first gear 32 is located on the inner side of the side wall of the mechanism frame 2, the inner side of the mechanism frame 2 is rotatably connected to a rotating circle 33, the outer middle part of the rotating circle 33 is fixedly connected to a gear ring 34, the lower right side of the gear ring 34 is meshed and connected with the upper left side of the first gear 32, and the left side of the mounting plate 4 is fixedly connected to the inner side of the rotating circle 33 near the upper left side.

[0027] It should be noted that the first motor 31 drives the first gear 32 to rotate, and when the first gear 32 rotates, it drives the ring gear 34 to rotate, and when the ring gear 34 rotates, it drives the rotating ring 33 to rotate, and when the rotating ring 33 rotates, it drives the conveying mechanism 5 to rotate.

[0028] like Figure 3 , Figure 4 As shown, the conveying mechanism 5 includes an electromagnetic telescopic rod 51, one end of which is fixedly connected to the inner side of the rotating circle 33, and two electromagnetic telescopic rods 51 are symmetrically distributed up and down, and the ends of the two electromagnetic telescopic rods 51 close to each other are fixedly connected to a rotating frame 52, and the inner sides of the two rotating frames 52 are rotatably connected to conveying rollers 53.

[0029] It should be noted that the electromagnetic telescopic rod 51 is a device that uses electromagnetic force to achieve telescopic movement. It is mainly composed of components such as an electromagnetic wire package, a bracket, a wire and a controller. The magnetic field generated by the electromagnetic wire package drives the telescopic rod to perform telescopic movement. The electromagnetic telescopic rod 51 drives the rotating frame 52 to move, causing the two conveying rollers 53 to approach or move away from each other, so that the conveying rollers 53 can clamp the composite pipe.

[0030] like Figure 4 , Figure 5 As shown, the left and right sides of the two conveying rollers 53 are rotatably connected with two movable blocks 54 that are symmetrically distributed on the left and right sides, and the front and rear sides of the four movable blocks 54 are movably sleeved with two limit rods 55 that are symmetrically distributed on the front and rear sides. The ends of the limit rods 55 that are away from each other are fixedly connected to the side of the rotating frame 52 away from the electromagnetic telescopic rod 51, and the outer sides of the eight limit rods 55 are movably sleeved with springs 56, and the springs 56 are located on the side of the movable block 54 close to the rotating frame 52.

[0031] It should be noted that the spring 56 pushes the movable block 54, causing the conveying roller 53 to be closely attached to the polyethylene composite pipe, which is beneficial to improving the stability of the composite pipe and preventing the composite pipe from being damaged when the electromagnetic telescopic rod 51 pushes the conveying rollers 53 to be close to each other.

[0032] like Figure 4 , Figure 5 As shown, the inner side of the rotating circle 33 is rotatably connected to two transmission rods 59 distributed symmetrically on the left and right sides, the upper side of the mounting plate 4 is fixedly connected to a second motor 57, the output end of the second motor 57 is fixedly connected to a second gear 58, the outer side of the transmission rod 59 on the left side near the upper side is fixedly connected to a third gear 510, the front side of the third gear 510 is meshed and connected with the rear side of the second gear 58, the left and right sides of the two conveying rollers 53 are rotatably connected to gear racks 511, the left and right sides of the two conveying rollers 53 are fixedly connected to first bevel gears 512, the transverse walls of the four gear racks 511 are rotatably connected to second bevel gears 513, and the left and right second bevel gears 513 on the same side are arranged symmetrically with respect to the center, the side of the second bevel gear 513 close to the rotating rack 52 is meshed and connected with the side of the first bevel gear 512 away from the conveying roller 53, and the inner side of the second bevel gear 513 is movably sleeved on the outer side of the transmission rod 59.

[0033] It should be noted that the second motor 57 drives the second gear 58 to rotate, and when the second gear 58 rotates, it drives the third gear 510 to rotate, and when the third gear 510 rotates, it drives the transmission rod 59 located on the left side to rotate, and when the transmission rod 59 rotates, it drives the second bevel gear 513 to rotate, and when the second bevel gear 513 rotates, it drives the first bevel gear 512 to rotate, and when the first bevel gear 512 rotates, it drives the conveying roller 53 to rotate.

[0034] like Figure 4 , Figure 5 As shown, sprockets 514 are fixedly connected to the outer sides of the two transmission rods 59 away from the third gear 510 , and the side surfaces of the sprockets 514 are meshedly connected with chains 515 .

[0035] It should be noted that when the transmission rod 59 on the left side rotates, it drives the sprocket 514 on the left side to rotate. When the left sprocket 514 rotates, the two transmission rods 59 rotate synchronously in the same direction by relying on the chain 515, so that the left and right sides of the conveying roller 53 are subjected to balanced force.

[0036] The working principle of the utility model is as follows: first, the first motor 31 drives the first gear 32 to rotate, and when the first gear 32 rotates, it drives the gear ring 34 to rotate, and when the gear ring 34 rotates, it drives the rotating circle 33 to rotate, and when the rotating circle 33 rotates, it drives the conveying mechanism 5 to rotate. The first motor 31 drives the rotating circle 33 to rotate, so that the conveying mechanism 5 rotates as a whole, so that when the conveying mechanism 5 conveys the composite pipe, the rotating mechanism 3 rotates it, and the two mechanisms are combined with each other, so that the device can synchronously operate the composite pipe conveying and rotation, avoiding mutual interference between components, and finally, the electromagnetic telescopic rod 51 drives the rotating frame 52 to move, so that the two conveying rollers 53 are close to or away from each other, so that the conveying rollers 53 can clamp the composite pipe, and the second motor 57 drives the second gear 58 to rotate, and the second gear 58 rotates. When the transmission rod 59 rotates, it drives the second bevel gear 513 to rotate. When the second bevel gear 513 rotates, it drives the first bevel gear 512 to rotate. When the first bevel gear 512 rotates, it drives the conveying roller 53 to rotate. When the transmission rod 59 on the left side rotates, it drives the sprocket 514 on the left side to rotate. When the left sprocket 514 rotates, the two transmission rods 59 are caused to rotate synchronously in the same direction by relying on the chain 515, so that the left and right sides of the conveying roller 53 are balanced in force. The electromagnetic telescopic rod 51 drives the rotating mechanism 3 to approach each other to clamp the composite pipe. The second motor 57 drives the conveying roller 53 to rotate synchronously in the opposite direction, so that the conveying roller 53 conveys the composite pipe, which is beneficial to reduce the burden on workers and improve work efficiency.
