Description

Technical Field

[0001] The utility model belongs to the technical field of ground film production, and specifically relates to an extrusion molding device for degradable ground film. Background Art

[0002] Ground film is a ground covering film, usually a transparent or black PE film, but also a green or silver film. It is used to cover the ground to increase soil temperature, retain soil moisture, maintain soil structure, prevent pests from attacking crops and diseases caused by certain microorganisms, etc., and promote plant growth.

[0003] The existing cooling device technology for mulch film extrusion production has the following problems: when the existing cooling device for mulch film extrusion production is in use, it is necessary to pull the extruded film upward from the protective frame, flatten it between two tight frames, and use a motor to drive the roller to drive the film outward. The film is naturally cooled through a higher frame. When the film is just extruded, it needs to be protected by the protective frame so that the diameter of the film will not be too large. When the equipment temperature of the machine is too high, the newly extruded film will expand outward more easily under the blowing of the fan, which will make the diameter of the processed film larger. Utility Model Content

[0004] The technical problems to be solved by the utility model are:

[0005] The ground film tends to expand outwards when blown by the fan, resulting in a larger film diameter.

[0006] In order to solve the above technical problems, the technical solution proposed in the utility model is: a degradable mulch extrusion molding device, including a silo, an extrusion assembly, a discharge adjustment assembly and a movable fan assembly, the extrusion assembly is installed at the bottom of the silo, the discharge adjustment assembly is threadedly connected to the top of the silo, the movable fan assembly is arranged in the discharge adjustment assembly, and a feed port is provided on the outer wall of the silo. The movable fan assembly includes a screw drive assembly and a fan, the screw drive assembly is vertically arranged at the bottom of the discharge adjustment assembly, and the fan is fixed to the screw drive assembly through a mounting frame plate.

[0007] Furthermore, the discharge adjustment component includes a film thickness adjustment shell, a circular threaded ring is defined on the film thickness adjustment shell by a connecting frame, an external thread is provided on the inner wall of the silo, the threaded ring and the external thread are threadedly connected, a fastening screw is threadedly connected on the outer wall of the silo, the fastening screw passes through the external thread and is set against the threaded ring, and the film thickness adjustment shell is set in the shape of a thin-walled cone.

[0008] Furthermore, the screw transmission assembly includes a screw mounting frame, a transmission motor, a threaded rod and a slider with a nut.

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] like Figure 1-3 As shown, the utility model proposes an extrusion molding device for a degradable mulch film, comprising a silo 1, an extrusion assembly 2, a discharge adjustment assembly 3 and a movable fan assembly 4, the extrusion assembly 2 is installed at the bottom of the silo 1, the discharge adjustment assembly 3 is threadedly connected to the top of the silo 1, the movable fan assembly 4 is arranged in the discharge adjustment assembly 3, and a feed port 5 is provided on the outer wall of the silo 1, the movable fan assembly 4 comprises a screw transmission assembly 7 and a fan 8, the screw transmission assembly 7 is vertically arranged at the bottom of the discharge adjustment assembly 3, the fan 8 is fixed to the screw transmission assembly 7 through a mounting frame plate, and a heating wire is provided in the inner wall of the silo 1. In order to realize the extrusion function, the extrusion assembly 2 comprises an extrusion motor 17 and an extrusion spiral disk 18, the extrusion motor 17 is fixedly arranged at the outer bottom of the silo 1 and the output shaft penetrates the silo 1, the extrusion spiral disk 18 is fixedly arranged on the output shaft of the extrusion motor 17, the extrusion spiral disk 18 is spirally arranged, and the outer side of the extrusion spiral disk 18 is arranged close to the inner wall of the silo 1.

[0023] In order to facilitate the adjustment of the extrusion thickness of the film, the discharge adjustment component 3 includes a film thickness adjustment shell 9, on which a circular threaded ring 10 is specified by a connecting frame, an external thread 11 is provided on the inner wall of the silo 1, and the threaded ring 10 and the external thread 11 are threadedly connected. A fastening screw 12 is threadedly connected on the outer wall of the silo 1, and the fastening screw 12 passes through the external thread 11 and is set against the threaded ring 10. The film thickness adjustment shell 9 is set in the shape of a thin-walled cone, and a discharge gap is set between the film thickness adjustment shell 9 and the silo 1, and two sets of handles 6 are set on the film thickness adjustment shell 9.

[0024] In order to adjust the tendency of the film to expand outward, the position of the fan 8 is adjusted. The fan 8 is far away from the discharge port and the relative effect between it and the film is weak. The screw transmission assembly 7 includes a screw mounting frame 13, a transmission motor 14, a threaded rod 15 and a slider with a nut 16. The screw mounting frame 13 is vertically arranged on the film thickness adjustment shell 9. The transmission motor 14 is fixedly arranged at one end of the screw mounting frame 13.

[0025] During specific use, the user places the device at the position where it needs to be used, adds the processed ground film into the silo 1 from the feed port 5, and the extrusion motor 17 drives the extrusion spiral disk 18 to extrude the raw material upward. The ground film is squeezed out from the gap between the film thickness adjustment shell 9 and the silo 1, and is formed into a film under the action of the fan 8. The transmission motor 14 can adjust the distance between the fan 8 and the discharge gap when it is running. When the fan 8 is away from the discharge gap, the expansion degree of the film decreases. When it is necessary to adjust the discharge amount of the film and thus change the film thickness, the fastening screw 12 is rotated away from the threaded ring 10. The user holds the handle 6 and rotates the film thickness adjustment shell 9. After the film thickness adjustment shell 9 moves upward, the gap between the silo 1 and the film thickness adjustment shell 9 increases. At this time, the thickness increases, and the fastening screw 12 is tightened against the threaded ring 10 to fix it. The above is the use process of the entire degradable ground film extrusion molding device.
