Technical Field

[0001] The utility model belongs to the technical field of profile extrusion anti-deflection equipment, in particular to a plastic profile extrusion anti-deflection device. Background Art

[0002] Plastic profiles refer to extruded plastic products with non-circular cross-sections, including corrugated, grooved, T-shaped, and other shapes. They are widely used in construction, decoration, and other fields. They have good dimensional accuracy and stable physical properties, and are important materials in construction, decoration, and other fields. Common examples include window frames, stair handrails, cable ducts, skirting boards, special-shaped pipes, and accessories such as furniture and building materials.

[0003] In the extrusion molding production of plastic profiles, air cooling is often used to cool the products. However, during the operation of the cooling equipment, the cooling speed is not uniform due to factors such as equipment temperature and coolant. This leads to uneven cooling effects in some areas of the profile. Under the influence of temperature differences, deformation and deviation are prone to occur, affecting the production quality of the profile.

[0004] In order to solve the above problems, this application proposes a plastic profile extrusion anti-deflection device. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-4 As shown, the utility model is a plastic profile extrusion anti-deflection device, comprising: a base 1 and a slide 2;

[0028] The side seat 3 is located at the front end of the base 1 and is connected to the front end of the slide 2 through the rear extension seat 4. The extension seat 4 is used to provide sliding space for the slide 2 to achieve the effect of extending the cooling interval to ensure sufficient cooling of the profile. The upper and lower ends of the slide 2 and the side seat 3 are internally provided with ventilation hoses 6 connected to the cold air cylinder 5 on the left side of the base 1;

[0029] The vertically symmetrical positioning shaft 15 is located between the two adjacent left and right supports 14 inside the base 1. Combined with the rotating shaft sleeves 17 on the outer sides of both ends, it forms a clamping effect on the profile, so that it is not affected by temperature changes during the cooling period to maintain the stability of the structure and prevent deformation and deviation.

[0030] This embodiment provides a plastic extrusion anti-deviation device with an adjustable cooling zone. The cooling process is performed by adjusting the zone length in real time, which can prevent the profile from being deformed and deviated due to temperature differences caused by insufficient cooling, thereby ensuring its production quality. At the same time, during the cooling period, it can resist the temperature difference deformation caused by cold wind by clamping on all four sides, ensuring that its structure is stable and adaptable to cooling operations of different efficiencies.

[0031] Among them, a sliding groove 7 is provided inside the right side of the base 1 for slidingly installing a slider 9 on the right side of the slide 2. A screw hole is opened inside the slider 9 to connect to the electric screw 8 on the right side of the base 1, so that the slide 2 can be moved outward at any time to increase the cooling area of ​​the profile and ensure its sufficient cooling.

[0032] The first cooling air ducts 10 are provided inside the upper and lower ends of the slide 2 and connected to the second cooling air ducts 11 inside the side seat 3 to adapt to different cooling zones of the slide 2 .

[0033] A cooling nozzle 13 is provided on a side surface of the first cold air duct 10 near the center of the base 1. The internal air holes of the cooling nozzle 13 near one end of the second cold air duct 11 are connected to the ventilation holes 12 inside the second cold air duct 11 to ensure that the performance of the cooling nozzle 13 is maintained after the cooling range is adjusted.

[0034] Secondly, the opening of the ventilation holes 12 can also pre-treat the profile to reduce the temperature, so that it can adapt to the high-efficiency cooling operation of the cooling nozzle 13.

[0035] Among them, a middle seat 16 is provided inside the slide 2, and the support 14 is installed through electric telescopic devices on the upper and lower sides. An elastic telescopic rod 18 is provided at one end of the rotating sleeve 17 to control the clamping force formed by the rotating sleeve 17. Through symmetrical clamping, the formation is always maintained in a predetermined position to resist temperature difference deformation during cooling operation.

[0036] The positioning shaft 15 and the support 14 are rotatably connected, and an annular mechanism is rotatably mounted on the inner sides of both ends of the support 14 for mounting the elastic telescopic rod 18 .

[0037] It can be understood that the utility model can adjust the length of the cooling zone in real time to adapt to the cooling needs of the profile to prevent insufficient cooling. In addition, the side of the profile can be limited during the cooling operation to resist deformation and deviation caused by the temperature difference between hot and cold, so that the profile structure is stable and the production quality is improved.

[0038] A specific application of the operating process of this embodiment is: when in use, first, the temperature of the profile after cooling is monitored in real time at the outlet end of the slide 2 through a temperature sensing instrument. After insufficient cooling is found, the slide 7 and the electric screw 8 cooperate to drive the slide 2 to slide with the profile to extend its cooling area so that it can achieve a sufficient cooling effect. During this period, the extension seat 4 is stretched and expanded to connect the side seat 3 and the slide 2 to maintain the internal cooling effect stable, and it is also convenient for the staff to find problems in time to adjust the equipment parameters; in addition, during the cooling period of the profile, the positioning shaft 15 and the rotating sleeve 17 can also be used to support its outer side in real time to keep its structure stable during temperature changes. After this arrangement, the profile can be effectively prevented from deformation and deviation due to temperature changes, thereby ensuring its production efficiency and product quality.
