Description

Technical Field

[0001] This utility model relates to blown film machine equipment, and more particularly to a fully biodegradable rope-string bag blown film machine. Background Technology

[0002] In the production process of plastic film, blown film machines are mainly used. The raw materials are heated to a molten state and extruded through the extrusion mechanism. Compressed air is used to blow out film bubbles to obtain film. Finally, the film is wound into a cylinder by the winding mechanism.

[0003] In the traditional blown film production process, the raw material is melted and extruded by the blown die head and blown into a cylindrical film tube. When the film passes through the blown film mechanism to the conveying mechanism, due to the long distance, it is easily affected by the external lateral wind force, causing the freshly produced film to flake and resulting in unqualified product quality. Therefore, a windproof drawstring bag blown film machine is needed to ensure the quality of product production. Utility Model Content

[0004] The purpose of this invention is to provide a fully biodegradable rope-string bag blown film machine, which can effectively ensure the production of the blown film machine and reduce the impact of external crosswinds, thus reducing work efficiency.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: This utility model provides a fully biodegradable drawstring bag blown film machine, including a heated extrusion mechanism. The upper end of the heated extrusion mechanism is provided with a hopper. A blown film mechanism is connected to one side of the heated extrusion mechanism. A support is provided on the outside of the blown film mechanism. A conveying mechanism is provided at the upper end of the support. An arc-shaped protective mechanism is provided between the conveying mechanism and the blown film mechanism. Arc-shaped protective mechanisms are provided on both the front and rear sides of the support. The two arc-shaped protective mechanisms are symmetrical. The arc-shaped protective mechanism includes an arc-shaped block, a connecting plate, an arc-shaped plate body, a slide groove, and a telescopic film assembly. A slide groove is provided on the arc-shaped plate body. Connecting plates are slidably connected to both sides of the slide groove. A limiting component is provided on the opposite side of the connecting plate. An arc-shaped block is provided on the other side of the connecting plate. A telescopic film assembly is connected to the side of the arc-shaped block near the arc-shaped plate body. The other side of the telescopic film assembly is placed inside the arc-shaped plate body.

[0006] Preferably, the telescopic membrane assembly includes a soft membrane, a spring, and a rotating shaft. The main body of the arc-shaped plate has slots on both sides, a spring is provided at the upper end of the slot, a rotating shaft is connected to the inner side of the spring, the rotating shaft is perpendicular to the horizontal plane, the soft membrane is fixedly connected to the rotating shaft, and the other end of the soft membrane is fixedly connected to the arc-shaped block.

[0008] Preferably, the support has a step on one side.

[0009] Preferably, the heating extrusion mechanism is equipped with a power distribution box at its front end, and the electrical components of the device are connected to the power distribution box by wires.

[0010] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0011] This invention incorporates an arc-shaped protective mechanism to prevent crosswinds from affecting the film as it is conveyed from the blown film mechanism to the conveying mechanism, thus ensuring the smooth production process.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] The components of this utility model, including the distribution box 1, bracket 2, conveying mechanism 3, arc-shaped protective mechanism 4, blown film mechanism 5, step 6, winding mechanism 7, heating extrusion mechanism 8, hopper 9, arc-shaped block 41, connecting plate 42, arc-shaped plate body 43, slide 44, telescopic film assembly 45, soft film 451, spring 452, and rotating shaft 453, are all general standard parts or parts known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0022] like Figure 1-4 As shown, this utility model provides a fully biodegradable rope bag blown film machine, including a heated extrusion mechanism 8, a hopper 9 at the upper end of the heated extrusion mechanism 8, a blown film mechanism 5 connected to one side of the heated extrusion mechanism 8, a support 2 on the outside of the blown film mechanism 5, a conveying mechanism 3 at the upper end of the support 2, and an arc-shaped protective mechanism 4 between the conveying mechanism 3 and the blown film mechanism 5.

[0023] In use, the film is extruded through the heating extrusion mechanism 8 into the blown film mechanism 5, and blown out into a cylindrical shape. The film enters the conveying mechanism 3 vertically upward for transport. The arc-shaped protective mechanism 4 can provide some protection for the film and reduce the impact of horizontal wind on the film. After entering the conveying mechanism 3, the film is sent to the winding mechanism 7 for winding under the action of the conveying mechanism 3.

[0024] The support 2 is equipped with arc-shaped protective mechanisms 4 on both the front and rear sides. The two arc-shaped protective mechanisms 4 are symmetrical in front and behind, which can effectively reduce the impact of lateral wind force on the film over a large area.

[0025] Combination Figure 3 As shown, the arc-shaped protective mechanism 4 includes an arc-shaped block 41, a connecting plate 42, an arc-shaped plate body 43, a sliding groove 44, and a telescopic membrane assembly 45. The outer side of the arc-shaped plate body 43 is bolted to the bracket 2. The arc-shaped plate body 43 is provided with a sliding groove 44, and the connecting plates 42 are slidably connected to both sides of the sliding groove 44. The opposite side of the connecting plates 42 is provided with a limiting component. The other side of the connecting plate 42 is provided with an arc-shaped block 41. The side of the arc-shaped block 41 closest to the arc-shaped plate body 43 is connected to the telescopic membrane assembly 45, and the other side of the telescopic membrane assembly 45 is placed inside the arc-shaped plate body 43. In use, the operator pulls the arc-shaped block 41 to move it outward, and the arc-shaped block 41 drives the telescopic membrane assembly 45 to slide in coordination, blocking the lateral wind force from affecting film production to the maximum extent.

[0026] Combination Figure 4 As shown, the telescopic membrane assembly 45 includes a soft membrane 451, a spring 452, and a rotating shaft 453. The arc-shaped plate body 43 has slots on both sides, with a spring 452 at the upper end of each slot. The rotating shaft 453 is connected to the inner side of the spring 452 and is perpendicular to the horizontal plane. The soft membrane 451 is fixedly connected to the rotating shaft 453, and the other end of the soft membrane 451 is fixedly connected to the arc-shaped block 41. The friction between the connecting plate 43 and the sliding groove is greater than the elastic force of the spring 452, preventing workers from pulling the arc-shaped block 41 to... After reaching the maximum distance from the main body 43 of the curved plate, it is pulled back by the spring force of the spring 452, which can effectively avoid wasted effort. The curved block 41 pulls and drives the soft film 451 to rotate and extend around the rotating shaft 453, blocking the lateral wind force from the blown film mechanism 5 to the conveying mechanism 3 to the maximum extent, thus affecting film production. Conversely, when the curved block 41 is retracted, the spring 452 drives the rotating shaft 453 to rotate in the opposite direction, causing the soft film 451 to wrap around the rotating shaft 453, which facilitates the disassembly of the curved protective mechanism 4 and saves time for later transportation and maintenance.

[0027] The front end of the support 2 is provided with a winding mechanism 7, and the input end of the winding mechanism 7 cooperates with the conveying mechanism 3.

[0028] The support 2 has a step 6 on one side, which makes it convenient for staff to access the conveying mechanism 3 for maintenance and component installation.

[0029] The heating extrusion mechanism 8 is equipped with a power distribution box 1 at its front end (which is well known to those skilled in the art based on the technical manual, so it will not be described in detail). The electrical components of this device are connected to the power distribution box 1 by wires, and the operator controls the start-up and operation of the device motor through the power distribution box 1.

[0030] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
