Problems solved by technology

However, because the method of adjusting the circulating water and vacuum negative pressure is a manual adjustment method, and this method requires the operator to conduct continuous fine-tuning and observation online, the technical ability of the operator is high, and the general operator cannot complete it at all. The goal of bending adjustment; at the same time, when this method of bending is used, online adjustments must be made again for each production, which takes a long time and has low production efficiency
Other methods of bending adjustment, such as the method of hot air baking, are not only complicated in installation, but also consume a lot of power and are not environmentally friendly. It will reduce the physical and chemical properties of the profile, so the method of hot air baking is only used when the profile with a large cross-section is bent
In summary, there is no effective means to solve the bending phenomenon of plastic profiles in the continuous extrusion process in the prior art.

Embodiment Construction

[0031] Such as Figure 1~4 As shown, a bending adjustment device used in the production of plastic profiles, the bending adjustment device includes a base 9, and the base 9 is provided with a reverse extrusion of the bending direction of the profile 15 so that the profile 15 can be straightened. Straight adjustable bend parts.

[0032] There are many ways to realize the bending parts, such as using a fixed side plate, and making the side wall of the continuously extruded plastic profile slide along the surface of the side plate, relying on the extrusion force of the fixed side plate to make the curved part of the plastic profile be corrected.

[0033] As a preferred solution of the present invention, the bending adjustment component is a roller 2, the roller 2 is sleeved on the roller shaft 3 and forms a rolling fit with the roller shaft 3, at least one end of the roller shaft 3 is fixedly connected to the guide rod 6, so The guide rod 6 is fixed on the base 9.

Abstract

The invention belongs to the technical field of plastic profile production, and particularly relates to a curve adjusting device used in plastic profile production. The curve adjusting device comprises a base, and a curve adjusting component used for extruding the profile along the direction opposite to the curving direction to straighten the profile is arranged on the base. The invention has good curve adjusting effect; when the plastic profile are extruded continuously and pass, the outer roller wall of a roller of the invention is used for compulsively extruding the curved part of the plastic profile, so as to correct the profile in the reverse direction, further ensure the flatness of the plastic profile; the roller in the invention can adjust profiles in different shape and size, as well as different curve degrees of the corresponding profile, and has a wide adjusting range; meanwhile the invention can classify the profiles based on the section sizes of the curved profiles, then the curve adjusting devices in the same type are designed to be standard, after that corresponding curve adjusting device can be directly applied to the profiles in the same type, so that standard production is easy to realize.

Description

technical field [0001] The invention belongs to the technical field of production of plastic profiles, and in particular relates to a bending adjustment device used in the production of plastic profiles. Background technique [0002] For the bending phenomenon of plastic profiles in the continuous extrusion process, it is usually solved by adjusting the circulating water and vacuum negative pressure. However, because the method of adjusting the circulating water and vacuum negative pressure is a manual adjustment method, and this method requires the operator to conduct continuous fine-tuning and observation online, the technical ability of the operator is high, and the general operator cannot complete it at all. The goal of bending adjustment; at the same time, when this method of bending adjustment is adopted, online adjustment must be carried out again every time production, which takes a long time and has low production efficiency. Other methods of bending adjustment, su...
