Description

Technical Field

[0001] This utility model relates to the field of thin film production technology, specifically to a forming device for thin film production. Background Technology

[0002] The production of single-layer film generally begins by feeding plastic raw materials into an extruder, where they are heated and melted by a screw, then extruded into a molten film preform through a specific die head. After cooling and shaping, the preform is pulled out by a traction device and a stretching device, and finally wound into a roll by a winding device to obtain the single-layer film product.

[0003] In the film production process, after the film is extruded by an extruder, it usually needs to be stretched to increase its width, improve its physical properties, and optimize its thickness uniformity. However, the existing stretching devices have obvious structural drawbacks. Their stretching process relies on a long stroke to achieve full stretching and extension of the film, which directly leads to a significant increase in the overall footprint of the equipment. In a factory environment, the excessively long stretching stroke not only increases space costs but also limits the flexibility of the production line layout. Therefore, we propose a forming device for film production. Utility Model Content

[0004] One of the technical problems that this application aims to solve is that after film extrusion, it needs to be stretched to increase the width, improve performance and thickness uniformity. However, existing stretching devices rely on long strokes, which results in large equipment footprints, increased space costs and limited production line layout flexibility.

[0005] To solve the above-mentioned technical problems, this application provides a molding apparatus for film production, including a housing, an extrusion chamber fixedly connected inside the housing, an extrusion head fixedly connected to one side of the extrusion chamber, and the extrusion head being arranged parallel to the housing;

[0006] The three stretching rollers are all housed inside the box and are arranged in a triangular pattern.

[0007] The adjustment assembly includes a triangular frame disposed within a housing. Three sets of first hydraulic rods are fixedly connected within the triangular frame. A connecting plate is fixedly connected to the driving end of each of the three sets of first hydraulic rods. A rectangular frame is fixedly connected to the outside of each of the three connecting plates. A slider is slidably connected within each of the three rectangular frames. Second hydraulic rods are disposed at both ends of each of the three sliders. Sliding sleeves are fixedly connected to both ends of each of the three rectangular frames. Three sets of sliding rods are fixedly connected to the outside of the triangular frame, and the three sets of sliding rods are slidably connected to the three sets of sliding sleeves respectively.

[0008] In some embodiments, the adjustment assembly is configured as two sets, with the three stretching rollers rotatably connected between the two sets of sliders.

[0009] In some embodiments, a connecting frame is fixedly connected to the outside of the triangular frame, a lifting block is fixedly connected to the outside of the connecting frame, a support frame is fixedly connected to the inside of the box, the lifting block extends into the support frame, a motor is fixedly connected to the top of the support frame, the drive end of the motor extends into the support frame and is fixedly connected to a lead screw, and the lead screw is threadedly connected to the lifting block.

[0010] In some embodiments, the connecting frame, lifting block, support frame, motor and lead screw are configured as two sets, which are arranged opposite to each other, and the two connecting frames are respectively fixedly connected to the two triangular frames.

[0011] In some embodiments, a first cooling fan is fixedly connected to the top of the housing, and a second cooling fan is fixedly connected to the bottom of the housing, with the first and second cooling fans arranged opposite to each other.

[0012] In some embodiments, two first upright plates are fixedly connected inside the box, and two first guide rollers are rotatably connected between the two first upright plates.

[0013] In some embodiments, two second upright plates are fixedly connected inside the box, and two second guide rollers are rotatably connected between the two second upright plates.

[0014] This utility model has at least the following beneficial effects:

[0015] After being guided by two first guide rollers, the film passes around three stretching rollers in an S-shaped path: first through the bottom of the nearest first stretching roller, then through the top of the parallel second stretching roller, and finally through the bottom of the bottom third stretching roller, and is finally exited by two second guide rollers. During this process, activating any one of the first hydraulic rods drives the corresponding stretching roller to move, thus stretching the film. Activating all three first hydraulic rods can further improve the stretching degree. During this process, the three stretching rollers are arranged in a triangular combination rather than a linear arrangement. This structural layout effectively reduces the space occupied by the equipment. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] Please see Figures 1-5 This utility model provides a technical solution:

[0024] A forming apparatus for film production includes a housing 1, with an extrusion chamber 2 of the prior art fixedly connected inside the housing 1 for extruding molten material. An extrusion head 3 is fixedly connected to one side of the extrusion chamber 2 and is arranged parallel to the housing 1, so that the film extruded by the extrusion head 3 can enter between two first guide rollers 14.

[0025] The three stretching rollers 4 are all set inside the box 1. The three stretching rollers 4 are arranged in a triangular pattern. The film can pass through the three stretching rollers 4 in an S-shape and then be guided out by the two second guide rollers 16.

[0026] Adjustment component 5 includes a triangular frame 51 disposed within the housing 1. Three sets of first hydraulic rods 52 are fixedly connected within the triangular frame 51. A connecting plate 53 is fixedly connected to the driving end of each of the three sets of first hydraulic rods 52. A rectangular frame 54 is fixedly connected to the outside of each of the three connecting plates 53. A slider 55 is slidably connected within each of the three rectangular frames 54. Second hydraulic rods 56 are disposed at both ends of each of the three sliders 55. Sliding sleeves 57 are fixedly connected to both ends of each of the three rectangular frames 54. Three sets of sliding rods 58 are fixedly connected to the outside of the triangular frame 51. The three sets of sliding rods 58 are slidably connected to the three sets of sliding sleeves 57 respectively. Adjustment component 5 is configured with two sets, and three spreading rollers 4 are rotatably connected between the two sets of sliders 55.

[0027] A connecting frame 6 is fixedly connected to the outside of the triangular frame 51. A lifting block 7 is fixedly connected to the outside of the connecting frame 6. A support frame 8 is fixedly connected inside the housing 1. The lifting block 7 extends into the support frame 8. A motor 9 is fixedly connected to the top of the support frame 8. The drive end of the motor 9 extends into the support frame 8 and is fixedly connected to a lead screw 10. The lead screw 10 is threadedly connected to the lifting block 7. The connecting frame 6, the lifting block 7, the support frame 8, the motor 9, and the lead screw 10 are set in two groups, which are arranged opposite to each other. The two connecting frames 6 are fixedly connected to the two triangular frames 51 respectively.

[0028] During operation: After being guided by the two first guide rollers 14, the film can pass around the three stretching rollers 4 in an S-shape. Then, any one of the first hydraulic rods 52 is activated to drive the corresponding stretching roller 4, which can stretch the film for stretching.

[0029] For example, the film can be stretched by passing through the bottom of the first stretching roller 4 at the nearest position, then through the top of the second stretching roller 4 at the parallel position, then through the bottom of the third stretching roller 4 at the bottom position, and finally exited by the two second guide rollers 16. During this process, as long as any one of the first hydraulic rods 52 drives the corresponding stretching roller 4 to move, the film can be stretched.

[0030] Furthermore, the corresponding drive of the second hydraulic rod 56 can fine-tune the relative position between the three stretching rollers 4, thereby fine-tuning the degree of film stretching;

[0031] Furthermore, the motor 9 is started, and the motor 9 drives the lead screw 10 to rotate, thereby driving the lifting block 7 to rise and fall, which in turn drives the two adjusting components 5 and the three stretching rollers 4 to rise and fall as a whole, so that the film can be stretched from different directions. For example, when the film passes over the two top stretching rollers 4, the two adjusting components 5 and the three stretching rollers 4 rise as a whole to stretch the film. For example, when the film passes over the bottom stretching roller 4, the two adjusting components 5 and the three stretching rollers 4 fall as a whole to stretch the film. Example 2

[0033] Unlike Embodiment 1, a first cooling fan 11 is fixedly connected to the top of the housing 1, and a second cooling fan 12 is fixedly connected to the bottom of the housing 1. The first cooling fan 11 and the second cooling fan 12 are arranged opposite to each other. The relative blowing of the first cooling fan 11 and the second cooling fan 12 can cool the film and further shape it.

[0034] Two first upright plates 13 are fixedly connected inside the housing 1. Two first guide rollers 14 are rotatably connected between the two first upright plates 13. Two second upright plates 15 are fixedly connected inside the housing 1. Two second guide rollers 16 are rotatably connected between the two second upright plates 15. The film is guided by the two first guide rollers 14, then stretched by the three stretching rollers 4, and finally discharged by the two second guide rollers 16.
