Description

Technical Field

[0001] The utility model relates to the technical field of textile equipment, in particular to a preparation device for low-strength and low-elongation polyester filaments. Background Art

[0002] Polyester yarn is known for its resistance to chemicals and frequent washing, minimizing fading and discoloration. This is why it's often used in hotel uniforms, stonewashed blue denim, sportswear, and children's clothing. Relatively speaking, polyester yarn is tougher than rayon. When embroidering, the machine runs at high speeds, and the high-strength polyester thread can withstand greater tension.

[0003] According to a publicly disclosed device for preparing low-strength and low-elongation polyester filament (publication number: CN214193545U), in the above application, the battery is started by a controller, and the battery enables the electromagnetic coil to convert electrical energy into thermal energy, so that the box is in a suitable preparation environment, and the motor is started. The output end of the motor is connected to the input end of the drive shaft through a coupling. The rotation of the motor drives the rotating shaft to rotate. A stirring paddle is nested on the outside of the drive shaft. The rotation of the drive shaft controls the stirring paddle to stir the polyester filament. The motor, drive shaft and stirring paddle are axially symmetrical along the central axis of the box, which can more effectively stir the molten polyester filament and increase its heating efficiency. Through the mutual cooperation of the battery, electromagnetic coil and stirring device, the polyester filament can be heated to a molten state, so that the heating is more uniform and the finished product is better.

[0004] However, in the aforementioned application, when the polyester yarn is melted and discharged from the box, some of the molten material adheres to the inner wall of the box. This adhered material is difficult to fall off naturally. Currently, cleaning this adhered material mainly relies on manual operation, which is not only time-consuming and labor-intensive, but also increases safety risks and labor costs during the production process. Utility Model Content

[0005] The purpose of the utility model is to provide a device for preparing low-strength and low-elongation polyester filaments to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a device for preparing low-strength and low-elongation polyester filaments, comprising a box body, a feed port being provided at the top of the box body, a discharge port being provided at the bottom of the box body, a closed door being installed on the surface of the discharge port, a cleaning assembly for cleaning the inner wall of the box body being provided inside and on the surface of the box body, the cleaning assembly comprising:

[0007] The cylinder is fixed on the top of the box body, the output end of the cylinder passes through the box body, a fixing ring is fixed to the bottom of the output end of the cylinder, the bottom of the fixing ring is slidably connected to a scraper 1, a sliding groove is provided at the bottom of the fixing ring, the inner wall of the sliding groove is slidably connected to a sliding rod, and a scraper 2 is fixed to the end of the sliding rod away from the sliding groove.

[0008] Preferably, the cleaning assembly also includes a resistance rod, which is fixed at the bottom of scraper one, and scraper two is located between the resistance rods, and the resistance rod is in resistance with the surface of scraper two. There are five groups of scraper one and scraper two, and the five groups of scraper one and scraper two are arranged in a circular array with the center of the fixed ring as the axis. A spring one is fixed between the five groups of scraper one. The cleaning assembly also includes a limiter. When the cylinder drives the fixed ring to move downward, scraper one and scraper two can clean the inner wall of the box without manual cleaning by personnel, thereby improving cleaning efficiency.

[0009] The top of described sliding panel also is provided with an interlocking structure, and the interlocking structure is designed so that the sliding panel also is in the interlocking position, and the sliding panel also is in the interlocking position, and the gear train is equipped with an on-off switch, and the on-off switch is equipped with a gear train that is arranged on the interlocking structure to interlock the gear train. The scraper surface contacts the inclined surface of the block, forcing it into the stabilizing groove and compressing spring 2. When the block aligns with the groove, spring 2 releases, allowing the block to enter the groove and retain the scraper. As the retaining ring moves upward, the scraper does not contact the inner wall of the box, preventing carryover of residue. When the retaining ring reaches the top of the box, the rack triggers the gear to rotate, driving the block away from the groove, releasing the retaining force. Spring 1 releases, allowing scrapers 1 and 2 to return to the inner wall of the box.

[0010] Preferably, a slot is provided at the bottom of the scraper 1, and a resistance block is fixed below the inner wall of the box body. The slot cooperates with the resistance block to limit the scraper 1. When the scraper 1 collides with the inclined surface of the resistance block, the scraper 1 can move.

[0011] Preferably, a motor is fixed on the top of the box, the output shaft of the motor passes through the box, a spiral stirring blade is fixed on the surface of the output shaft of the motor, an air outlet is provided on the top of the box, an activated carbon filter element is fixed on the top of the air outlet, an annular cavity is provided inside the box, a heating rod is installed on the inner wall of the annular cavity, the heating rod is started to melt the polyester yarn, and the motor drives the spiral stirring blade to improve the heating efficiency.

[0012] Preferably, the side of the clamping block away from the second spring and close to the first scraper is configured as an inclined surface, and when the inclined surface is abutted, the clamping block can enter the stable groove.

[0013] Preferably, the top of the interference block is configured as an inclined surface, which can cause the scraper to move when it interferes with the scraper.

[0014] Compared with the prior art, the present invention provides a device for preparing low-strength and low-elongation polyester filaments, which has the following beneficial effects:

[0015] 1. The preparation device of low-strength and low-elongation polyester filament has a cleaning component. When the cylinder drives the fixed ring to move downward, scrapers 1 and 2 can clean the inner wall of the box, without the need for manual cleaning by personnel, thereby improving cleaning efficiency. Through the limiter, scrapers 1 and 2 will only fit against the inner wall of the box when the fixed ring moves downward. When moving upward, scrapers 1 and 2 are away from the inner wall of the box to avoid residue being driven, resulting in incomplete cleaning, thereby improving cleaning efficiency.

[0016] 2. The low-strength and low-elongation polyester filament preparation device can start the motor to rotate the spiral stirring blade, thereby stirring the molten polyester filament and making it heat more evenly. BRIEF DESCRIPTION OF THE DRAWINGS

There is a sliding rod 84, and a scraper 2 85 is fixed at one end of the sliding rod 84 away from the slide groove 83. The cleaning component 8 also includes a resistance rod 87, which is fixed to the bottom of the scraper 1 82. The scraper 2 85 is located between the resistance rod 87, and the resistance rod 87 is in resistance with the surface of the scraper 2 85. There are five groups of scrapers 1 82 and scrapers 2 85, and the five groups of scrapers 1 82 and scrapers 2 85 are arranged in a circular array with the center of the fixed ring 81 as the axis. A spring 1 86 is fixed between the five groups of scrapers 1 82. The cleaning component 8 also includes a limiter 88. The cylinder 80 drives the fixed ring 81 to reciprocate up and down, and the scrapers 1 82 and scrapers 2 85 then fit into the inner wall of the box 1 to scrape off the residue.

[0026] The limiting member 88 includes a connecting groove 880, which is provided at the bottom of the fixing ring 81. A fixing block 881 is fixed to the inner wall of the connecting groove 880. A stabilizing groove 882 is provided at the bottom of the fixing block 881. A clamping block 883 is slidably connected to the inner wall of the stabilizing groove 882. A spring 2 884 is fixed to the surface of the clamping block 883. The end of the spring 2 884 away from the clamping block 883 is fixed to the inner wall of the stabilizing groove 882. The inner wall of the connecting groove 880 is rotatably connected to a gear 885. The inner wall of the connecting groove 880 is slidably connected to a rack 1 886. The top of the rack 1 886 passes through the fixing ring 81. The surface of the fixing block 881 is slidably connected to a rack 2 889. A through hole 887 is provided on the surface of the fixing block 881. A fixing rod 888 is fixed to the surface of block 883. The end of fixing rod 888 away from block 883 passes through through-hole 887. The end of fixing rod 888 away from block 883 is fixed to the surface of rack 2 889. Rack 1 886 and rack 2 889 both mesh with gear 885. A slot 8801 is provided at the bottom of scraper 1 82. A resistance block 8800 is fixed to the lower inner wall of housing 1. The side of block 883 away from spring 2 884 and closer to scraper 1 82 is configured as an inclined surface. The top of resistance block 8800 is configured as an inclined surface. When scraper 1 82 moves to the bottom of housing 1, the inclined surface of resistance block 8800 causes it to move toward the center, compressing spring 1 86 and simultaneously pushing resistance rod 87 to move scraper 2 85 synchronously. The chute 83 and slide rod 84 ensure the stable movement of scraper 2 85. The surface of scraper 1 82 contacts the inclined surface of block 883, causing it to enter the stable groove 882 and compress spring 2 884. When the position of block 883 is parallel to the groove 8801, spring 2 884 is released and block 883 enters the groove 8801 to limit scraper 1 82 and scraper 2 85. When the fixed ring 81 moves upward, scraper 1 82 and scraper 2 85 do not contact the inner wall of the box 1 to avoid bringing back residue. When the fixed ring 81 reaches the top of the box 1, the top of rack 1 886 contacts the top of the inner wall of the box 1, causing the gear 885 to rotate, and rack 2 889 drives the block 883 to move away from the groove 8801, releasing the limit. Spring 1 86 is released to reset scraper 1 82 and scraper 2 85 and re-fit with the inner wall of the box 1, improving the cleaning effect and preventing residue from being brought back, resulting in incomplete cleaning.

[0027] A motor 10 is fixed on the top of the box body 1, and the output shaft of the motor 10 passes through the box body 1. A spiral stirring blade 11 is fixed on the surface of the output shaft of the motor 10. An air outlet 5 is provided on the top of the box body 1, and an activated carbon filter element is fixed on the top of the air outlet 5. An annular cavity 6 is provided inside the box body 1, and a heating rod 7 is installed on the inner wall of the annular cavity 6.

[0028] When in use, polyester yarn is put into the feed port 2, and the heating rod 7 is turned on to heat and melt it. At the same time, the motor 10 is turned on to make the spiral stirring blade 11 stir it to improve its heating efficiency. The hot air generated is discharged through the air outlet 5 and filtered by the activated carbon filter element. When the processing is completed and needs to be discharged for further processing, the closed door 4 is opened to discharge it. When there is residue adhering to the inner wall of the box body 1, the cylinder 80 is turned on to reciprocate, which can drive the fixed ring 81 to reciprocate up and down. When the fixed ring 81 moves down, the scraper 82, The scraper 2 85 fits with the inner wall of the box 1, and can scrape and clean the residue of the box 1. When the scraper 1 82 is at the bottom of the box 1, the inclined surface of the friction block 8800 conflicts with the surface of the scraper 1 82, so that the scraper 1 82 moves close to the center of the box 1. At the same time, the spring 1 86 is compressed, and when the scraper 1 82 moves, it drives the friction rod 87 to move synchronously. At this time, the friction rod 87 conflicts with the surface of the scraper 2 85, so that the scraper 2 85 moves synchronously close to the center of the box 1. The movement of the scraper 2 85 is stabilized by the slide groove 83 and the slide rod 84. At this time, the surface of the scraper 1 82 When the clamping block 883 is in the stable groove 882, the spring 2 884 is compressed. When the clamping block 883 is parallel to the clamping groove 8801, the spring 2 884 is released, and the clamping block 883 enters the clamping groove 8801, which allows the clamping block 883 to limit the clamping groove 8801 and the scraper 1 82. At this time, the scraper 1 82 and the scraper 2 85 are separated from the inner wall of the box body 1. When the fixing ring 81 moves up, the scraper 1 82 and the scraper 2 85 will not conflict with the inner wall of the box body 1, which can avoid bringing back residue. When the fixing ring 81 is at the top of the box body 1, the rack 1 The top of 886 contacts the top of the inner wall of the box body 1, thereby driving the gear 885 to rotate. At this time, the rack 2 889 drives the fixed rod 888 and the block 883 to move away from the slot 8801, so that the block 883 disengages from the slot 8801, and the limit on the scraper 1 82 is released. At this time, the spring 1 86 is released, so that the scraper 1 82 and the scraper 2 85 can be reset and fit with the inner wall of the box body 1 again. When the cylinder 80 continues to work back and forth, the scraper 1 82 and the scraper 2 85 can reciprocate and fit with the inner wall of the box body 1, thereby improving the cleaning effect and avoiding the residue being driven, resulting in incomplete cleaning.

[0029] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
