Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of MPP pipe production, in particular to a traction device for MPP pipe production. Background Technique
[0002] MPP pipes are mainly made of modified polypropylene and have the characteristics of high temperature resistance and external pressure resistance. The production process of MPP pipes is as follows: feeding, plasticizing and extruding, die shaping, cooling and shaping, traction, sawing the pipes, and finished product winding. Among them, the equipment used for traction is a traction machine, whose function is to pull the plastic pipe after extrusion molding out of the die head and then send the plastic pipe into the pipe cutting machine.
[0003] Most current pipe traction devices drive the contact blocks to move through conveyor belts, and the contact blocks contact the outer wall of the pipe. Therefore, under the action of friction, the pipe is pulled to move. Most of the sides of the contact blocks close to the pipe are arc-shaped, which can increase the contact area with the arc-shaped outer wall of the pipe, thereby increasing the friction between the two. However, this kind of traction device can only be applied to circular pipes and cannot be used for square pipes, so the applicability is not good. Content of the Utility Model
[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a traction device for MPP pipe production, so as to solve the technical problems mentioned in the above background technique.
[0005] The above technical purpose of the utility model is achieved through the following technical solutions:
[0006] A traction device for MPP pipe production includes a housing with an opening on one side. Through holes are provided on both opposite sides of the housing, and the MPP pipe passes through the two through holes. Conveyor belts are arranged on both the upper and lower halves inside the housing. A number of substrates are evenly and fixedly connected to the surface of the conveyor belts. A first plate and a second plate are fixedly connected to the side of the substrate away from the conveyor belt. A rotating rod is rotatably connected to one side of the first plate. A linkage plate is fixedly connected to the end of the rotating rod away from the first plate. An arc plate and a flat plate are respectively fixedly connected to both opposite sides of the linkage plate. A fixing part is arranged on the side of the linkage plate away from the first plate.
[0007] By adopting the above technical solution, the positions of the arc plate and the flat plate are exchanged through the fixing part, so as to carry out traction operations on round pipes or square pipes, improving the applicability of the device.
[0008] Further, the fixing portion includes a transverse groove formed on one side of the linkage plate close to the second plate. A sliding rod is slidably inserted through one side of the second plate. One end of the sliding rod close to the linkage plate is fixedly connected to a side plate. A spring is fixedly connected between the side plate and the second plate. One side of the side plate away from the second plate is fixedly connected to a transverse plate, and a part of the transverse plate is inserted into the transverse groove.
[0009] By adopting the above technical solution, when it is necessary to traction the square pipe, pull the sliding rod outwards to drive the transverse plate out of the transverse groove, then rotate the linkage plate to exchange the positions of the arc plate and the flat plate, and then release the sliding rod. The transverse plate is inserted into the transverse groove to fix the linkage plate, so that the flat plate is located on the outermost side of the conveyor belt, and thus the square pipe can be tractioned.
[0010] Further, a turntable is fixedly connected to one end of the sliding rod away from the side plate.
[0011] Further, the conveyor belt includes a frame, and a plurality of electric push rods are fixedly connected between the frame and the inner top wall or the inner bottom wall of the housing.
[0012] By adopting the above technical solution, when it is necessary to traction pipes with different diameters or widths, the distance between the two conveyor belts can be adjusted by the electric push rods, thereby further improving the applicability of the present device.
[0013] Further, the two conveyor belts are mirror-symmetrically arranged with respect to the horizontal central plane of the through hole.
[0014] Further, the side wall of the transverse plate is in contact with the inner wall of the corresponding transverse groove.
[0015] By adopting the above technical solution, during the working process of the conveyor belt, since the side wall of the transverse plate is in contact with the inner wall of the transverse groove, the linkage plate will not shake relative to the conveyor belt, ensuring the stability of the traction operation.
[0016] In summary, the present utility model includes at least one of the following beneficial technical effects:
[0017] 1. For the traction device for MPP pipe production, when it is necessary to traction the square pipe, pull the sliding rod outwards to drive the transverse plate out of the transverse groove, then rotate the linkage plate to exchange the positions of the arc plate and the flat plate, and then release the sliding rod. The transverse plate is inserted into the transverse groove to fix the linkage plate, so that the flat plate is located on the outermost side of the conveyor belt, and thus the square pipe can be tractioned, improving the applicability of the present device;
[0018] 2. For the traction device for MPP pipe production, when it is necessary to traction pipes with different diameters or widths, the distance between the two conveyor belts can be adjusted by the electric push rods, thereby further improving the applicability of the present device.

Specific embodiments
[0026] The following further elaborates on the present utility model in detail with reference to the accompanying drawings. Embodiment
[0027] Refer to Figures 1 to 5 , a traction device for MPP pipe production disclosed by the present utility model includes an outer shell 1 with an open side. Through holes 2 are provided on both opposite sides of the outer shell 1, and the MPP pipe passes through the two through holes 2. Conveyor belts 3 are provided in both the upper half and the lower half inside the outer shell 1, and the two conveyor belts 3 are mirror-symmetrically arranged with respect to the horizontal central plane of the through holes 2.
[0028] A plurality of base plates 4 are evenly and fixedly connected to the surface of the conveyor belt 3, a first plate 5 and a second plate 6 are fixedly connected to the side of the base plate 4 away from the conveyor belt 3, a rotating rod 7 is rotatably connected to one side of the first plate 5, an end of the rotating rod 7 away from the first plate 5 is fixedly connected to a linkage plate 8, an arc plate 9 and a flat plate 10 are fixedly connected to opposite sides of the linkage plate 8, and a fixing portion 11 is provided on the side of the linkage plate 8 away from the first plate 5.
[0029] In this embodiment, the MPP pipe passes through the gap between the two conveyor belts 3 and the two through holes 2, and then passes through the housing 1 for traction. The side of the arc plate 9 away from the linkage plate 8 is set in an arc shape, and the side of the flat plate 10 away from the linkage plate 8 is set horizontally. In the initial state, the linkage plate 8 is in a horizontal state, and the arc plate 9 is located on the side of the linkage plate 8 away from the conveyor belt 3. At this time, the device can pull the round pipe.
[0030] When the round tube is pulled, a plurality of arc plates 9 are in contact with the outer circumference of the round tube. When the conveyor belt 3 is working, the arc plates 9 are driven to move, and the arc plates 9 drive the round tube to move horizontally through the friction between the arc plates 9 and the round tube, thereby pulling the round tube through the housing 1. The side of the arc plates 9 away from the linkage plate 8 is rough.
[0031] In a further preferred embodiment of the present invention, Figure 5 As shown, the fixing portion 11 includes a transverse groove 111 opened on the side of the linkage plate 8 close to the second plate 6, a sliding rod 112 is slidably penetrated on one side of the second plate 6, and the end of the sliding rod 112 close to the linkage plate 8 is fixedly connected to a side plate 113, a spring 114 is fixedly connected between the side plate 113 and the second plate 6, and a transverse plate 115 is fixedly connected to the side of the side plate 113 away from the second plate 6, and the transverse plate 115 is partially inserted into the transverse groove 111.
[0032] In this embodiment, when the square tube needs to be pulled, the staff pulls the slide bar 112 outward to drive the horizontal plate 115 out of the horizontal groove 111, and then rotates the linkage plate 8 to exchange the positions of the arc plate 9 and the flat plate 10, and then releases the slide bar 112, and the horizontal plate 115 is inserted into the horizontal groove 111 to fix the linkage plate 8, so that the flat plate 10 is located at the outermost side of the conveyor belt 3. At this time, the conveyor belt 3 can drive the square tube to be pulled when working. The side of the flat plate 10 away from the linkage plate 8 is rough.
[0033] In a further preferred embodiment of the present invention, Figure 4 As shown, one end of the sliding rod 112 away from the side plate 113 is fixedly connected to the rotating disk 12 .
[0034] In this embodiment, the turntable 12 facilitates the staff to pull the sliding rod 112 .
[0035] In a further preferred embodiment of the present utility model, as Figure 1 shown, the conveyor belt 3 includes a frame 31, and a plurality of electric push rods 32 are fixedly connected between the frame 31 and the inner top wall or the inner bottom wall of the outer shell 1.
[0036] In this embodiment, when the electric push rod 32 works, it can drive the frame 31 to move vertically, so as to adjust the distance between the two conveyor belts 3. Therefore, this device can tow round tubes with different diameters or square tubes with different widths, further improving the applicability of this device.
[0037] In a further preferred embodiment of the present utility model, as Figure 5 shown, the side wall of the cross plate 115 is in close fit with the inner wall of the corresponding cross groove 111.
[0038] In this embodiment, during the working process of the conveyor belt 3, since the side wall of the cross plate 115 is in close fit with the inner wall of the cross groove 111, the linkage plate 8 will not shake relative to the conveyor belt 3, ensuring the stability of the towing operation.
[0039] The implementation principle of the above embodiment is as follows:
[0040] In the initial state, the conveyor belt 3 works, driving the arc plate 9 to move. The arc plate 9 drives the round tube to move horizontally through the friction force with the round tube, so as to tow the round tube through the outer shell 1.
[0041] When it is necessary to tow a square tube, the staff pulls the sliding rod 112 outwards to drive the cross plate 115 out of the cross groove 111, then rotates the linkage plate 8 to exchange the positions of the arc plate 9 and the flat plate 10, and then releases the sliding rod 112. The cross plate 115 is inserted into the cross groove 111 to fix the linkage plate 8, so that the flat plate 10 is located on the outermost side of the conveyor belt 3. At this time, when the conveyor belt 3 works, it can drive the square tube for towing, improving the applicability of this device.
[0042] When the electric push rod 32 works, it can drive the frame 31 to move vertically, so as to adjust the distance between the two conveyor belts 3. Therefore, this device can tow round tubes with different diameters or square tubes with different widths, further improving the applicability of this device.
