Description

Technical Field

[0001] This utility model relates to the technical field of FIBC processing, specifically to a flat wire drawing machine for FIBC processing. Background Technology

[0002] As an important processing technology for FIBCs (Flexible Intermediate Bulk Containers), drawing is generally completed by a corresponding drawing machine. It uses polypropylene and high-density ethylene as raw materials, which are heated, extruded, split, and stretched to form flat filaments. After being wound up, they are fed to a circular loom for weaving. The drawing mechanism of the drawing machine is the core of the entire plastic woven drawing machine. Its structure consists of a frame, a drive structure, and drawing rollers. The raw materials are wound on the drawing rollers, and the action of the drawing rollers achieves the stretching treatment of the plastic woven filaments.

[0003] An existing patent publication number, CN222064786U, describes a wire drawing mechanism for a plastic weaving machine. This mechanism utilizes a designed assembly base, a cleaning block, and a spring. The assembly base, containing the cleaning block, is installed on one side of the corresponding wire drawing roller. The spring applies elastic pressure to the cleaning block, causing its end face to adhere to the surface of the wire drawing roller. During the rotation of the wire drawing roller, the cleaning block promptly scrapes away and cleans the plastic weaving raw materials and debris from the roller surface, ensuring the roller surface remains smooth at all times and preventing any impact on the wire drawing effect. Designed guide cylinders and guide pillars provide support and correction for the spring, preventing excessive bending and loss of elasticity. A designed reinforcing plate supports and reinforces the connection points of the assembly base, preventing cracking and improving the assembly stability of this invention. Designed limiting pillars and limiting holes limit the cleaning block, preventing it from detaching from the assembly base.

[0004] However, the cleaning block is a one-piece design, which makes it inconvenient to replace and clean, and its practicality is insufficient. Utility Model Content

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a flat yarn drawing machine for processing bulk bags, which has the following advantages:

[0015] Multiple sets of mounting bolts pass synchronously through the base mounting frame and the brush holder, and are fixed on the outside by nuts, forming a fixed connection between the brush and the base mounting frame. When running, the electromagnet is energized, causing the electromagnet to attract the ferromagnetic block. The base mounting frame is then in the upper position via a sliding rod, and the brush disengages from the wire drawing roller. The wire drawing machine body then rotates the wire drawing roller to draw the wire. When cleaning is required, the electromagnet is de-energized, and under the elastic action of the spring, the sliding rod slides down inside the sliding sleeve, moving the base mounting frame down so that the brush adheres to the upper surface of the wire drawing roller. As the wire drawing roller rotates, the brush cleans the surface of the wire drawing roller. After the mounting bolts and nuts are removed, the brush holder can be removed from the base mounting frame, and the brush can be taken out for replacement or cleaning. This design features an automatic contact cleaning structure with automatic adsorption and disengagement, facilitating loading and unloading operations and improving practicality.

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.

[0022] Example

[0023] Please see Figure 1-4A flat yarn drawing machine for processing container bags includes a drawing machine body 1 and a drawing roller 2. The drawing roller 2 is provided at the output end of the drawing machine body 1. It also includes an extension frame 3, a top frame 4, an electromagnet 5, a sliding sleeve 6, a sliding rod 7, a ferromagnetic block 8, a spring 9, a bottom mounting frame 10, a brush frame 11, a brush 12, mounting bolts 13, and nuts 14. The upper front middle side of the drawing machine body 1 is connected to the rear side of the extension frame 3, and the outer side of the middle top of the extension frame 3 is connected to the bottom end of the top frame 4. The top of the top frame 4 is connected to the top of the electromagnet 5. The inner side of the middle of the extension frame 3 is connected to the outer side of the sliding sleeve 6. The inner wall of the sliding sleeve 6 is slidably connected to the outer wall of the sliding rod 7. The top of the sliding rod 7 is connected to the bottom of the ferromagnetic block 8. The bottom of the sliding rod 7 is connected to the middle of the top of the bottom mounting frame 10. A spring 9 is connected to the outer side of the sliding rod 7 at the top of the bottom mounting frame 10 and the outer side of the sliding sleeve 6 at the bottom of the extension frame 3. The bottom of the brush holder 11 is connected to the top of the brush 12. Multiple sets of mounting bolts 13 are connected together. The brush 12 passes through the bottom mounting bracket 10 and the brush holder 11, and is fixed on the outside by nuts 14. Multiple sets of mounting bolts 13 simultaneously pass through the bottom mounting bracket 10 and the brush holder 11, and are fixed on the outside by nuts 14, forming a fixed connection between the brush 12 and the bottom mounting bracket 10. During operation, the electromagnet 5 is energized, causing it to attract the ferromagnetic block 8. The bottom mounting bracket 10 is then in the upper position via the slide rod 7, and the brush 12 disengages from the drawing roller 2, allowing the drawing machine body 1 to... The drawing roller 2 is used for drawing wire. When cleaning is required, the electromagnet 5 is de-energized. Under the elastic action of the spring 9, the slide bar 7 slides down inside the slide sleeve 6, and the bottom mounting bracket 10 is moved down, so that the brush 12 is attached to the upper surface of the drawing roller 2. As the drawing roller 2 rotates, the brush 12 acts on the surface of the drawing roller 2 for cleaning. After the mounting bolt 13 and nut 14 are removed, the brush holder 11 can be removed from the bottom mounting bracket 10, and then the brush 12 can be taken out for replacement or cleaning.

[0024] It also includes an oil nozzle 15, with one side of the upper part of the outer end of the sliding sleeve 6 connected to the inner side of the oil nozzle 15; oil can be injected into the inner wall of the sliding sleeve 6 through the oil nozzle 15, which facilitates the contact and lubrication between the sliding sleeve 6 and the sliding rod 7 and avoids jamming.

[0025] It also includes an oil filling cap 16, and the outer side of the oil filling nozzle 15 and the inner side of the oil filling cap 16 can be detachably installed; after the oil filling cap 16 is installed on the outer side of the oil filling nozzle 15, the inside of the oil filling nozzle 15 can be sealed and protected to prevent dust contamination and improve reliability.

[0026] It also includes a mounting base 17 and a recycling frame 18. The bottom of the inside of the wire drawing machine body 1 is connected to the bottom of the mounting base 17. The recycling frame 18 can be detachably installed inside the mounting base 17. Installing the recycling frame 18 inside the mounting base 17 allows the recycling frame 18 to be located on the bottom side inside the wire drawing machine body 1, thereby absorbing cleaning impurities. After the recycling frame 18 is removed, it is easy to empty, improving convenience.

[0027] It also includes a tightening sleeve 19, a tightening screw 20, and a tightening handle 21. The middle right side of the mounting base 17 is connected to the inner side of the tightening sleeve 19. The inner wall of the tightening sleeve 19 is screwed to the outer wall of the tightening screw 20. The outer side of the tightening screw 20 is connected to the middle inner side of the tightening handle 21. By turning the tightening handle 21, the tightening screw 20 is rotated. The tightening screw 20, through its screw engagement with the tightening sleeve 19, acts inward to tighten the outer side of the recycling frame 18 at that position, thus fixing the recycling frame 18 and improving reliability.

[0028] In summary, in the operation of a flat yarn drawing machine for processing container bags, multiple sets of mounting bolts 13 simultaneously pass through the bottom mounting frame 10 and the brush frame 11, and are fixed on the outside by nuts 14, forming a fixed connection between the brush 12 and the bottom mounting frame 10. When running, the electromagnet 5 is energized, causing the electromagnet 5 to attract the ferromagnetic block 8. The bottom mounting frame 10 is in the upper position via the sliding rod 7, and the brush 12 is disengaged from the drawing roller 2. The drawing machine body 1 acts on the drawing roller 2 to rotate and draw the yarn. When cleaning is required, the electromagnet 5 is de-energized. Under the elastic action of the spring 9, the sliding rod 7 slides down inside the sliding sleeve 6, moving the bottom mounting frame 10 down, so that the brush 12 adheres to the upper surface of the drawing roller 2. As the drawing roller 2 rotates, the brush 12 acts on the surface of the drawing roller 2 for cleaning, and the mounting bolts are also removed. After 13 and nut 14 are disassembled, the brush holder 11 can be removed from the bottom mounting bracket 10, and the brush 12 can be taken out for replacement or cleaning. In addition, oil can be injected into the inner wall of the sliding sleeve 6 through the oiling nozzle 15 to facilitate the contact and lubrication between the sliding sleeve 6 and the sliding rod 7 and avoid jamming. After the oiling cap 16 is installed on the outside of the oiling nozzle 15, the inside of the oiling nozzle 15 can be sealed and protected to prevent dust contamination. The recycling frame 18 is installed inside the mounting sleeve 17. By turning the tightening handle 21, the tightening screw 20 is rotated. The tightening screw 20 is screwed into the tightening screw sleeve 19 and acts inward to tighten the recycling frame 18 at this position on the outside, fixing the recycling frame 18. This allows the recycling frame 18 to be located on the bottom side inside the wire drawing machine body 1, thus receiving the cleaned impurities. After the recycling frame 18 is removed, it is easy to pour out.

[0029] The wire drawing machine body 1 and the electromagnet 5 are commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, and we will not elaborate further here.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
