Description

Technical Field

[0001] The utility model belongs to the field of extrusion molding devices and relates to an extrusion molding device for weather-resistant film materials. Background Art

[0002] A weather-resistant film material is a film-like material with excellent weather resistance, and an extrusion molding device for weather-resistant film materials is a device specifically used for producing weather-resistant film materials. Usually, a single-screw or twin-screw extruder is used to heat and melt raw materials such as resin and additives of the weather-resistant film material and then extrude them. The performance of the extruder directly affects the quality and production efficiency of the film material.

[0003] However, in the extrusion molding device for weather-resistant film materials, there is no overall material winding thickness monitoring device during the winding process of the film finished product. Due to the absence of a thickness monitoring device, it is difficult to accurately judge when the specified winding amount is reached, which may lead to either insufficient winding and the need for re-winding operations, wasting time and resources, or over-winding, increasing the workload of subsequent processing. In either case, the production efficiency will be reduced. Therefore, it is necessary to design an extrusion molding device for weather-resistant film materials with a winding state monitoring function to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an extrusion molding device for weather-resistant film materials with reasonable space utilization in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved by the following technical solutions:

[0006] An extrusion molding device for weather-resistant film materials, characterized in that it includes an equipment bin and a base table. The upper end of the base table is fixedly connected with an extrusion material pipe. A pair of flat pressing roller shafts are installed inside the base table. One end of the equipment bin close to the base table is provided with a guiding roller shaft. One end of the equipment bin far from the base table is fixedly connected with an extending cross bar. A winding roller shaft is installed at the end of the extending cross bar far from the equipment bin. There is a driving motor outside the winding roller shaft. Inner vertical grooves are symmetrically opened on the upper sides of the left and right inner walls of the winding roller shaft. A follower roller shaft is slidably connected between the two inner vertical grooves. A movable transverse plate is movably connected in the inner vertical groove on the right side. A contact sensor is fixedly connected to the lower end of the movable transverse plate. The contact sensor is located directly above the follower roller shaft.

[0007] In the above extrusion molding device for weather-resistant film materials, the follower roller shaft and the contact sensor cooperate with each other. Side inner clamping grooves are symmetrically opened on the left and right inner walls of the inner vertical groove.

[0008] In the above-mentioned extrusion molding device for weather-resistant film materials, an inner cavity is provided at the inner end of the movable transverse plate, and inner push rods are slidably connected to the left and right inner walls of the movable transverse plate.

[0009] In the above-mentioned extrusion molding device for weather-resistant film materials, inner contraction springs are fixedly connected to the mutually approaching ends of the two inner push rods, and engaging abutting blocks are fixedly connected to the ends of the inner push rods close to the inner side slots.

[0010] In the above-mentioned extrusion molding device for weather-resistant film materials, the two engaging abutting blocks are respectively engaged with the corresponding inner side slots on both sides, and a water cooling tank is fixedly connected between the equipment bin and the base table.

[0011] In the above-mentioned extrusion molding device for weather-resistant film materials, a spraying mechanism is externally connected to the water cooling tank, and a weather-resistant film material is extruded from the output end of the extrusion material pipe.

[0012] In the above-mentioned extrusion molding device for weather-resistant film materials, the weather-resistant film material extends to the position between a pair of flat pressing roller shafts, and the weather-resistant film material penetrates inside and outside the equipment bin and is wound around the outside of the winding roller shaft.

[0013] Compared with the prior art, in the extrusion molding device for the weather-resistant film material of the present invention, a follower roller shaft that slides up and down through inner vertical grooves can be arranged inside the winding roller shaft. The follower roller shaft can be arranged above the roll of the weather-resistant film material and gradually lift up as the weather-resistant film material is wound and thickened until it contacts the contact sensor below the movable transverse plate at the top of the inner vertical groove. After receiving the contact signal, the contact sensor can send a material taking signal to the staff through an externally connected control terminal. By setting the follower roller shaft as a thickness monitoring device, the winding thickness of the weather-resistant film material can be detected in real time, improving production efficiency. At the same time, the contact sensor under the movable transverse plate serves as the detection point for the winding thickness. By pressing the two inner push rods, the inner push rods can be squeezed into the inner cavity through the inner contraction springs, and the position of the movable transverse plate can be adjusted up and down. After adjustment, the two inner push rods are released, and the inner contraction springs bounce outward. The two engaging abutting blocks bounce outward into the corresponding inner side slots for limit fixation, which can facilitate improving the flexibility of use of the movable transverse plate.

The term "or / and" used herein includes any and all combinations of one or more of the related listed items.

[0022] Such as Figure 1As shown in FIG. 4, the extrusion molding device of the weather-resistant film material includes an equipment bin 1 and a base table 2. The upper end of the base table 2 is fixedly connected with an extrusion material pipe 3. A pair of flat pressing roller shafts 5 are installed inside the base table 2. A guiding roller shaft 4 is arranged at one end of the equipment bin 1 close to the base table 2. One end of the equipment bin 1 far from the base table 2 is fixedly connected with an extension cross bar 17. A winding roller shaft 7 is installed at the end of the extension cross bar 17 far from the equipment bin 1. There is a driving motor outside the winding roller shaft 7. Inner vertical grooves 8 are symmetrically opened on the upper sides of the left and right inner walls of the winding roller shaft 7. A follower roller shaft 11 is slidably connected between the two inner vertical grooves 8. A movable transverse plate 9 is movably connected in the inner vertical groove 8 on the right side. The lower end of the movable transverse plate 9 is fixedly connected with a contact sensor 10. The contact sensor 10 is located directly above the follower roller shaft 11.

[0023] The follower roller shaft 11 and the contact sensor 10 cooperate with each other. Side inner clamping grooves 12 are symmetrically opened on the left and right inner walls of the inner vertical groove 8.

[0024] An inner cavity bin 16 is opened at the inner end of the movable transverse plate 9. Inner pushing bar shafts 13 are slidably connected to the left and right inner walls of the movable transverse plate 9.

[0025] The ends of the two inner pushing bar shafts 13 close to each other are fixedly connected with a retraction spring 14. The end of the inner pushing bar shaft 13 close to the side inner clamping groove 12 is fixedly connected with a clamping and abutting block 15.

[0026] Both of the two clamping and abutting blocks 15 are clamped with the corresponding side inner clamping grooves 12. A water cooling tank 6 is fixedly connected between the equipment bin 1 and the base table 2.

[0027] The water cooling tank 6 is externally connected with a spraying mechanism. The output end of the extrusion material pipe 3 extrudes a weather-resistant film material.

[0028] The weather-resistant film material extends to the position between a pair of flat pressing roller shafts 5, passes through the inside and outside of the equipment bin 1, and is wound around the outside of the winding roller shaft 7.

[0029] This solution can mix the raw materials of the weather-resistant film material according to a certain formula ratio and add them to the extrusion pipe 3. The extrusion pipe 3 heats and melts the raw materials, and through the rotation and extrusion of the internal screw rod therein, the molten material is extruded into the output end. Through the die style at the output end, the molten material is formed into the required shape and thickness of the weather-resistant film material. The extruded weather-resistant film material passes through the water-cooling tank 6, and the external spraying mechanism of the water-cooling tank 6 quickly cools and solidifies it to ensure the dimensional stability and performance of the film material. The cooled film material is evenly pulled by the guiding roller shaft 4 into the equipment bin 1 and flattened by two flat pressing roller shafts 5. After being flattened, the weather-resistant film material is wound around the outer side of the winding roller shaft 7 into a coil with a certain length and diameter for subsequent transportation. When the weather-resistant film material is wound around the outer side of the winding roller shaft 7, a follower roller shaft 11 that slides up and down through the internal vertical groove 8 can be arranged inside the winding roller shaft 7. The follower roller shaft 11 can be arranged above the weather-resistant film material roll and lift up as the weather-resistant film material gradually winds and thickens until it contacts the contact sensor 10 under the movable horizontal plate 9 at the top of the internal vertical groove 8. After receiving the contact signal, the contact sensor 10 can send a material-taking signal to the staff through an external control terminal. By setting the follower roller shaft 11 as a thickness monitoring device, the winding thickness of the weather-resistant film material can be detected in real time. When the specified winding amount is reached, a signal can be sent in time to pause the winding operation so as to remove the finished product. This avoids the situation of insufficient or excessive winding, reduces the time for repeated operations and adjustments, and improves the production efficiency. At the same time, the contact sensor 10 under the movable horizontal plate 9 as the monitoring point for the winding thickness can push the two inner push rods 13 into the inner cavity bin 16 by pressing the two inner push rods 13, squeezing them through the inner contraction spring 14, adjust the position of the movable horizontal plate 9 up and down. After adjustment, release the two inner push rods 13, and the inner contraction spring 14 rebounds outward, and the two engaging abutting blocks 15 rebound outward into the corresponding inner side card slots 12 for limit fixation, which can facilitate improving the use flexibility of the movable horizontal plate 9.

[0030] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0031] Those of ordinary skill in the art in this technical field should recognize that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. As long as within the scope of the essential spirit of the present invention, appropriate changes and variations made to the above embodiments fall within the scope of protection required by the present invention.
