Description

Technical Field

[0001] The invention relates to the technical field of socks equipment, in particular to a residue cleaning component for plastic dot coating on sock soles. Background Art

[0002] The sock dispensing device is a kind of equipment suitable for anti-slip treatment of socks. Its main function is to apply plastic dots on the socks to increase their friction coefficient, thereby improving the anti-slip performance of the product. Generally, plastic particles are dotted on the bottom of the molded socks.

[0003] The current sock dispensing device has some shortcomings. The dispensing nozzle first contacts the sock sole, then slowly rises upward, and the plastic flows out of the dispensing nozzle and drips onto the sock sole. During this process, the plastic overflows and adheres to the edge of the dispensing nozzle. The continuous accumulation of solidified plastic will gradually shrink the glue outlet hole, thereby affecting the subsequent dispensing effect. The traditional method is to replace the dispensing nozzle and then clean the replaced dispensing nozzle. This method is inefficient and labor-intensive for workers. Summary of the invention

DETAILED DESCRIPTION

[0029] The embodiment of the present invention provides a sock sole plastic dot-coating residue cleaning component, such as Figure 1-8 As shown, it is arranged near the nozzle 2, including a syringe 1, a small electric push rod 12 is fixedly installed at the bottom center of the syringe 1, the small electric push rod 12 is vertically welded to the nozzle 2 downward, the syringe 1 is connected to the nozzle 2, and a cleaning component 3 is arranged at the bottom of the syringe 1, and the working end of the cleaning component 3 can be fitted with the outer surface of the lower half of the nozzle 2.

[0030] The cleaning assembly 3 includes a toothed ring 31, a plurality of scrapers 4, a motor 5 and a leather strap 6. The toothed ring 31 is pivotally connected to the bottom of the syringe 1, the toothed ring 31 and the nozzle 2 are arranged in a concentric circle, the scrapers 4 are arranged around the nozzle 2, the upper end of the scrapers 4 is slidably matched with the bottom of the toothed ring 31, the leather strap 6 passes through the plurality of scrapers 4 in sequence, the motor 5 is fixedly connected to the bottom of the toothed ring 31, and both ends of the leather strap 6 are fixedly tied to the transmission shaft of the motor 5.

[0031] The motor 5 rotates and tightens the leather strip 6, so that the scrapers 4 are brought closer to each other, so that the lower end of the scrapers 4 fits the lower end of the nozzle 2. Then the drive gear 31 rotates, and the gear 31 drives the scrapers 4 to rotate. In this way, the solidified plastic remaining on the lower half of the nozzle 2 is scraped off, achieving the purpose of cleaning the residue.

[0032] It also includes a tightness testing component, which is used to sense whether the leather strap 6 is loose.

[0033] The tightness test assembly includes a hollow sleeve 7, a rotating block 71, a tension sensor 72, a large spring 73, and a rotating piece 74. The end of the rotating block 71 is slidably matched with the front end of the sleeve 7, and the rotating block 71 can move forward when the rotating block 71 rotates first.

[0034] A slide groove 711 is provided in the rotating block 71, and the front end of the transmission shaft of the motor 5 is slidably matched with the slide groove 711. The tension sensor 72 is fixedly installed at the end of the rotating block 71, the rotating piece 74 is pivotally connected to the inner wall of the sleeve 7, and the rotating piece 73 is fixedly connected to the tension sensor 72 through a large spring 74. The rotating piece 74 can only rotate and cannot move forward and backward.

[0035] The slide slot 711 is in a "Z" shape, and the cross section of the transmission shaft of the motor 5 is in a "T" shape. Through this matching mode, when the motor 5 drives the rotating block 7 to rotate, the rotating block 7 can move forward and extend out of the sleeve 7.

[0036] The transmission shaft of the motor 5 is parallel to the sleeve 7 , and the end of the leather strip 6 is fixedly bound to the front end of the rotating block 71 .

[0037] When the residue treatment is not performed, the leather strip 6 is in a relaxed state, the scraper blade 4 is away from the nozzle 2, and the motor 5 is not working. At this time, the tension sensor 72 does not measure the tension.

[0038] When residue treatment is required, the small electric push rod 12 contracts so that the nozzle 2 is surrounded by the cleaning assembly 3, the motor 5 drives the rotating block 71 to rotate, the belt 6 is wound around the rotating block 71, and the belt 6 is rolled up to bring the scraper 4 closer to the nozzle 2. As the belt 6 is continuously tightened, the rotating block 71 extends out of the sleeve 7. During this process, the rotating block 71 drives the tension sensor 72 to move. Since the position of the rotating piece 74 remains unchanged, the large spring 73 is stretched, and the tension sensor 72 senses the tension and transmits the data to the outside world through wireless transmission.

[0039] When the tension reaches the preset value, the scraper 4 fits with the nozzle 2. When the leather strap 6 is used for a long time, the elastic potential energy is weakened, and the recovery ability of the leather strap 6 becomes weak, so the leather strap gradually becomes longer, and it takes a longer time to reel. At this time, it takes more time to reach the preset tension value. It is judged whether the leather strap 6 needs to be replaced according to the feedback time of the tension sensor 72.

[0040] The toothed ring 31 is provided with a circular hole, the nozzle 2 is located at the circular hole, a slide bar 32 is welded at the bottom of the toothed ring 31, the upper end of the scraper 4 is slidably matched with the slide bar 32, the slide bar 32 has a flange at one end facing the nozzle 2, a small spring 34 is sleeved on the body of the slide bar 32, one end of the small spring 34 is welded to the scraper 4, and the other end of the small spring 34 is welded to the flange of the slide bar 32. The flanged end of the slide bar 32 does not contact the nozzle 2. The small spring 34 keeps the scraper 4 away from the nozzle 2 when not working.

[0041] A support rod 33 is welded to the bottom of the gear ring 31 , the lower end of the support rod 33 is fixedly mounted to the motor 5 , and an extension section 331 is welded to the support rod 33 , and the extension section 331 is fixedly mounted to the surface of the sleeve 7 .

[0042] The scraper blade 4 is distributed in a ring around the nozzle 2, and the lower end of the scraper blade 4 can fit the nozzle 2. A hoop 41 is provided on the outer side of the scraper blade 4, and the leather strip 6 passes through the hoop 41. A sliding hole 42 adapted to the sliding rod 32 is opened on the upper end of the scraper blade 4, and a small protrusion 43 is provided on the inner side of the lower end of the scraper blade 4. The scraper blade 4, the hoop 41 and the small protrusion 43 are integrally formed.

[0043] The small protrusion 43 can be embedded in the glue outlet of the nozzle 2 and fit with the inner wall of the glue outlet. When the scraper 4 fits with the nozzle 2, the small protrusion 43 fits with the inner wall of the glue outlet, which plays a role in improving the cleaning effect.

[0044] The collecting barrel 8 is also provided with a rotating bar 81 hinged on the top of the collecting barrel 8 . The upper end of the rotating bar 81 is connected to a motor 82 . The transmission shaft of the motor 82 is connected to a gear 83 . The gear 83 is meshed with the gear ring 31 .

[0045] An annular groove 14 is provided at the bottom of the syringe 1, and the gear ring 31 is slidably matched with the annular groove 14. A large electric push rod 11 is fixedly installed on the top of the syringe 1, and is fixedly installed together with the frame of the entire plastic dispensing equipment through the large electric push rod 11.

[0046] A material injection pipe 13 is fixedly installed and connected between the syringe 1 and the nozzle 2 .

[0047] In summary, the residue cleaning component for the plastic coating on the sock sole is provided with a toothed ring 31 outside the nozzle 2, and a scraper 4 is slidably matched at the bottom of the toothed ring 31. A plurality of scrapers 4 are connected in series through a leather strip 6. A motor 5 is provided at the bottom of the toothed ring 31. The leather strip 6 is rolled up by the motor to make the scraper 4 fit the nozzle 2, and the toothed ring 31 is driven to rotate, so as to clean the glue outlet of the nozzle 2 and scrape off the plastic attached to the glue outlet. This avoids the continuous accumulation of residues that causes the glue outlet to shrink or even become blocked, and replaces traditional manual work to achieve automatic cleaning.
