Description

Technical Field

[0001] This utility model relates to pipe equipment, and more particularly to a pipe traction machine. Background Technology

[0002] After being extruded from the extruder, plastic pipes undergo cooling and shaping processes before entering the traction wheel of the traction machine. The traction wheel uses surface friction to pull the pipe, maintaining its straightness and stability, and transports it to the next process. In existing technologies, most pipes are moved by a drive wheel equipped with a power unit that contacts the pipe. This requires the drive wheel to maintain continuous contact with the pipe to ensure effective traction. During this process, pressure exists between the drive wheel and the pipe to maintain friction. Since the pipe has not yet been protected after exiting the extruder, this pressure can cause scratches to the outer wall of the pipe. Therefore, the pipe traction machine needs optimization. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a pipe traction machine, which solves the problem that the existing technology requires continuous contact with the pipe when traction, which may cause scratches to the pipe and affect product quality.

The drive unit is fixedly mounted on the sliding tables and is used to drive the sliding tables to reciprocate on the guide rail.

[0005] The technical principle of this utility model is as follows: the main motor drives the adjusting sleeve to rotate along the contact sleeve, which reduces the inner diameter of the contraction section of the contact sleeve to fix the pipe and then drives the pipe to move.

[0015] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0016] like Figure 1As shown in the figure, this utility model embodiment proposes a pipe traction machine. A cooling device is installed at the discharge section of the extruder, and the pipe enters the traction machine after exiting the cooling device. This traction machine includes a guide rail 1 and two or more sliding tables 2. The sliding tables 2 are slidably connected to the guide rail 1. The guide rail 1 is fixedly positioned below the pipe's moving trajectory. The sliding table 2 is equipped with a contact sleeve 3, an adjusting sleeve 4, a main motor 7, and a drive unit. The contact sleeve 3 is adapted to the pipe diameter and has a gap. The contact sleeve 3 is fixedly connected to the sliding table 2, and the axis of the contact sleeve 3 is parallel to the extension line of the guide rail 1. The pipe produced by the extruder can pass through the contact sleeve 3. A contraction section 9 is provided at the end of the contact sleeve 3. The outer side of the contraction section 9 is tapered, and a slit 12 parallel to the axis of the contact sleeve 3 is arranged around the contraction section 9, thus dividing the contraction section 9 into several long, arc-shaped plates. The portion of the contraction section 9 away from the middle of the contact sleeve 3 can elastically contract. The adjusting sleeve 4 is threadedly connected to the contraction section 9. When the adjusting sleeve 4 rotates, the inner diameter of the contraction section 9 decreases, increasing the friction between the inside of the contraction section 9 and the pipe, thereby fixing the contact sleeve 3 and the pipe relatively. The main motor 7 is fixedly mounted on the sliding table 2, and a first gear 8 is fixedly mounted on the output shaft of the main motor 7. A second gear is sleeved on the outside of the adjusting sleeve 4, and the first gear 8 and the second gear mesh. Changing the rotation direction of the first gear 8 driven by the main motor 7 adjusts the axial position of the contact sleeve 3 on the adjusting sleeve 4, so that the contact sleeve 3 and the pipe are locked or released. The drive unit is fixedly mounted on the sliding table 2 and is used to drive the sliding table 2 to reciprocate on the guide rail 1. When the drive unit drives the pipe forward, the main motor 7 controls the first gear 8 to lock the inner hole of the contraction section 9. When the drive unit drives the sliding table 2 backward, the main motor 7 controls the first gear 8 to rotate in the opposite direction, creating a gap between the inner hole of the contraction section 9 and the pipe. After the contraction section 9 at the end of the contact sleeve 3 is fixed relative to the pipe, the drive unit drives the sliding table 2 to move, and the contact sleeve 3 fixed on the sliding table 2 will drive the pipe to move. Two or more sliding platforms 2 move forward alternately, allowing the pipe to move continuously forward. In subsequent processing, the area where the contact sleeve 3 contacts the pipe can be cut off and recycled, and the pipe in the area between the two contact sleeves 3 can be sold externally, thus ensuring quality.

[0017] Preferably, the drive unit includes an auxiliary motor 5 and a third gear 6. The auxiliary motor 5 is fixedly mounted on the sliding table 2, and the third gear 6 is fixedly mounted on the output shaft of the auxiliary motor 5. A strip tooth 10 is fixedly mounted on the guide rail 1, and the third gear 6 meshes with the strip tooth 10. The auxiliary motor 5, through the rotation of the third gear 6, causes the sliding sleeve to slide along the guide rail 1. The auxiliary motors 5 on each sliding table 2 alternately change their rotation direction, thereby ensuring that a sliding table 2 always moves, driving the pipe to move.

[0018] Preferably, the contact sleeve 3 includes an inner layer and an outer layer, the inner layer being made of rubber and the outer layer being made of metal. The rubber material increases friction, and the outer metal layer is machined with external threads to improve service life.

[0019] Preferably, the top surface of the guide rail 1 is provided with a T-slot 11, and the bottom of the sliding table 2 is fixedly provided with a sliding connector, the T-slot 11 and the sliding connector being adapted to each other. The T-slot 11 makes the sliding table 2 more stable when moving along the guide rail 1.

[0020] like Figure 2 As shown, preferably, the sliding table 2 and the contact sleeve 3 are fixedly connected at the middle. Both ends of the contact sleeve 3 are provided with contraction sections 9 and adjustment sleeves 4. The main motor 7 is a dual-axis motor, and the first gear 8 is fixedly mounted on the output shafts at both ends of the main motor 7. The external threads at both ends of the contact sleeve 3 have opposite directions of rotation. The contraction sections 9 at both ends of the contact sleeve 3 increase the contact area of ​​the pipe, allowing the contact sleeve 3 to better fix the pipe.

[0021] Preferably, the contact sleeve 3 and the sliding table 2 are detachably connected. When the rubber material inside the contact sleeve 3 is worn out, disassembling the contact sleeve 3 facilitates better maintenance.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
