Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of coiled material processing, and in particular to a coiled material extrusion device. BACKGROUND

[0002] PET coiled material, especially PET self-adhesive coiled material, as a kind of waterproof material with economic, practical and environmental protection characteristics, has shown wide application potential in modern architecture, packaging and various industrial fields. Its production process is precise and efficient, starting from the accurate proportioning of polyester chips, plasticizers, antioxidants and pigments and other raw materials. These components are fully fused under the action of high temperature in the melt extruder, and then form a continuous coiled material shape through the precise control of the extruder discharge port. Then, the coiled material obtains uniform and standard thickness under the careful adjustment of the extrusion roller, ensuring the performance and quality of the final product.

[0003] However, in the production process of PET coiled material, one technical challenge that cannot be ignored is the accurate control and subsequent processing after coiled material extrusion. The existing PET coiled material extrusion device is usually composed of a base and an upper extruder. The base is equipped with two rotating extrusion rollers. Through the driving of the first motor, a precise extrusion gap is formed between the two rollers to accurately adjust the thickness of the sheet material just output from the extruder. Although this design effectively improves the forming quality of the coiled material, it also brings difficulties in cleaning and maintenance.

[0004] Specifically, when the coiled material passes through the extrusion gap, it may adhere to the outer surface of the extrusion roller due to material properties or operating conditions. This problem can be better solved by regularly cleaning the outer surface of the extrusion roller, because the rotating design of the extrusion roller facilitates the intervention of cleaning tools. However, the base part located directly below the two extrusion rollers is difficult to access due to the narrow space, becoming a blind spot for cleaning work. Long-term accumulation of impurities not only affects the appearance and hygiene of the equipment, but also may adhere to the coiled material again when it passes through, causing surface defects of the finished product, seriously reducing product quality and customer satisfaction, and there is room for improvement.

[0017] Optionally, a scraper is fixed on the side of the cleaning plate away from the cleaning rod.

[0032] The present application will be further described in detail below with reference to all the accompanying drawings.

[0033] Example 1:

[0034] Reference Figure 1 A roll extrusion device includes a base 1, wherein an extrusion roller 11 is rotatably mounted on the base 1 and a first motor 12 is fixedly mounted to drive the extrusion roller 11 to rotate; support rods 13 are hinged to the opposite sides of the base 1, and a forming roller 14 is provided on the base 1 between the two support rods 13 and parallel to the extrusion roller 11.

[0035] The two ends of the forming roller 14 are rotatably connected to two support rods 13 respectively. A second motor 15 that drives the forming roller 14 to rotate is fixed on the side of one of the support rods 13. The first motor 12 and the second motor 15 are both conventional motors, and their specific structures will not be described in detail here.

[0036] The base 1 has a drive component 2 on its side that drives the support rod 13 to rotate. When the support rod 13 rotates, it drives the forming roller 14 to move back and forth toward the extrusion roller 11. When it is necessary to clean the part of the base 1 directly below the extrusion roller 11 and the forming roller 14, the operator can increase the gap between the forming roller 14 and the extrusion roller 11 by using the drive component 2.

[0037] With reference to Figure 1 , the driving member 2 is a driving cylinder 21, a protruding plate 16 is fixed on the side surface of the base 1; one end of the driving cylinder 21 is hinged to the protruding plate 16, and the other end is hinged to the end of the supporting rod 13 away from the extrusion roller 11; when the driving cylinder 21 operates, the overall length of the driving cylinder 21 is adjusted, thereby controlling the rotation of the supporting rod 13, and finally driving the forming roller 14 to act.

[0038] With reference to Figure 1 , two opposite fixed blocks 3 are slidably arranged on the base 1, and a power member 4 is fixedly arranged to drive the fixed blocks 3 to reciprocate towards the extrusion roller 11; wherein the power member 4 is a power cylinder 41 fixedly arranged at one end of the base 1, and the telescopic rod end of the power cylinder 41 is fixedly connected to the side surface of the fixed block 3 away from the extrusion roller 11;

[0039] The two fixed blocks 3 are located on the side of the extrusion roller 11 away from the forming roller 14, and the base 1 is provided with a cooling roller 5 located between the two fixed blocks 3 and having a length parallel to the extrusion roller 11, wherein the two ends of the cooling roller 5 are rotatably connected to the two fixed blocks 3, and one of the fixed blocks 3 is fixedly provided with a third motor 6 for driving the cooling roller 5 to rotate;

[0040] After the sheet is extruded by the extrusion roller 11 and the forming roller 14, it is cooled by the cooling roller 5, and then wound by a winding device; the cooling roller 5 is a conventional cooling member, which generally sprays cooling water directly onto the inner wall of the roller body through an internal nozzle or spraying system, and then uses the convection heat exchange characteristics of water to take away the heat of the roller body and the material in contact with it. The specific structure inside is not described here.

[0041] With reference to Figure 1 and Figure 2 , the base 1 is symmetrically provided with a slide rail 17 below the fixed block 3, and a slide groove 31 is formed in the lower side surface of the fixed block 3 for the slide rail 17 to slide; the cross-sectional shape of the slide rail 17 and the slide groove 31 is an I-shaped profile, so as to improve the stability of the fixed block 3 during sliding.

[0042] With reference to Figure 1 and Figure 3 , the side surface of the base 1 is fixedly provided with a limiting plate 7, wherein the limiting plate 7 is integrally formed with a limiting block 71 located above the driving cylinder 21, and a rubber elastic pad 711 is fixed on the side surface of the limiting block 71 facing the driving cylinder 21 by glue; after the limiting plate 7 is installed, the limiting block 71 can limit the rotation range of the driving cylinder 21, and the setting of the elastic pad 711 reduces the possibility of damage to the driving cylinder 21 and the limiting block 71 due to bumping.

[0043] The implementation principle of the embodiment of the present application is:

[0044] When the part of the base 1 directly below the extrusion roller 11 and the forming roller 14 needs to be cleaned, the staff starts the driving cylinder 21, and then increases the overall length of the driving cylinder 21, and controls the forming roller 14 on the support rod 13 to rotate away from the extrusion roller 11, facilitating subsequent cleaning.

[0045] Embodiment 2:

[0046] With reference to Figure 4 and Figure 5 , the difference between the embodiment of the application and embodiment 1 is that the side of the base 1 is provided with a cleaning assembly 8, wherein the cleaning assembly 8 comprises a cleaning rod 81 and a cleaning plate 82 fixed at one end of the cleaning rod 81, wherein the outer periphery of the cleaning plate 82 is fixed with a cleaning cotton 83 of sponge material; and two limiting snap rings 72 for the cleaning rod 81 to be clamped into are fixed on the side of the limiting plate 7;

[0047] When cleaning the extrusion equipment, the cleaning rod 81 can be taken out from the limiting snap ring 72, and then the cleaning rod 81 is held by hand, and the cleaning cotton 83 is used to clean the place that needs to be cleaned; the scraper 84 is fixed on the side edge of the cleaning plate 82 away from the cleaning rod 81, so that the scraper 84 on the cleaning plate 82 can be used to clean stubborn impurities.
