Description

TECHNICAL FIELD

[0001] The present application relates to the field of denim garment production and processing technology, in particular to a denim garment desizing device before washing. BACKGROUND

[0002] Desizing, as the name implies, is to remove the "sizing" applied to denim during weaving, but this sizing layer makes denim stiff and lacks elasticity, and also hinders the subsequent washing effect (such as cat whiskers, horse marks, etc.), and affects the penetration of dyes and chemicals. Therefore, it is necessary to remove it through the desizing process. For denim garments, desizing is usually done after garment forming. During the washing process, cellulase and other biological enzymes are used to decompose and remove the sizing (and part of the dye, producing a fading effect) on the denim pants. This process is essentially a desizing process, but it is combined with stone grinding and rinsing to achieve a unique appearance and soft hand feel.

[0003] The current desizing equipment in the workshop is mainly an industrial washing machine. The formed denim garment is placed in the washing machine, then the desizing liquid is added, the washing machine is started for desizing treatment, then the desizing liquid is discharged, and then clean water is injected for cleaning. This process can only handle a small amount of clothing each time, and the operation is complicated. The clothing is easily wrinkled due to high-speed stirring inside.

[0004] Therefore, in order to correct the above-mentioned defects, we propose a denim garment desizing device before washing. SUMMARY

The outlet of the uphill pipeline I is connected with the draining pipeline.

[0009] The desizing liquid source is connected to the desizing pipe through a pipeline to input the desizing liquid into the desizing pipe. A drain pipe is installed at the bottom of the desizing pipe to discharge the desizing liquid.

[0010] Carriers are installed at equal intervals on the flexible conveyor chain, and the carriers movably carry garment clamps.

[0011] Furthermore, it also includes a clean water source, a horizontal cleaning pipe including a clean water cleaning pipe, an uphill pipe including an uphill pipe two, a downhill pipe including a downhill pipe two, the outlet of the drain pipe is connected to the downhill pipe two, the outlet of the downhill pipe two is connected to the clean water cleaning pipe, the outlet of the clean water cleaning pipe is connected to the uphill pipe two, and the outlet of the uphill pipe two is connected to the horizontal discharge pipe.

[0012] Sewage pipes are also installed at the bottom of the sunken end of the second downhill pipe and at the bottom of the clean water cleaning pipe. The clean water source is connected to the clean water cleaning pipe through the pipe.

[0013] Furthermore, the carrier includes a base mounted on a single chain plate of a flexible conveyor chain, and a clamping ring is mounted on the base;

[0014] The garment clamp includes a sleeve, a large bearing is installed on the outside of the sleeve, the large bearing is inside the clamping ring, and two trouser leg rods are installed on one side of the sleeve.

[0015] Flexible conveyor chains drive carriers and garment clamps through horizontal feeding pipes, horizontal cleaning pipes, uphill pipes, downhill pipes, horizontal unloading pipes, and concave pipes.

[0016] Furthermore, the carrier also includes a drive device for rotating the garment clamps. The drive device includes a rack installed in the horizontal cleaning pipe, the uphill pipe, and the downhill pipe, a secondary bearing sleeved on the outside of one end of the sleeve extending from the large bearing, and a gear ring connected to the end of the sleeve extending from the large bearing. The secondary sleeve is sleeved on the secondary bearing, and one end of the secondary sleeve extends into the clamping ring. A vertical rod is installed on the top of the secondary sleeve, a horizontal bar is installed on one side of the vertical rod, a small bearing is installed on one side of the horizontal bar, a shaft passes through the small bearing, a gear is connected to the top of the shaft, the gear meshes with the rack, and a bevel gear is connected to the bottom of the shaft, the bevel gear meshes with the gear ring.

[0017] Furthermore, the carrier also includes a diagonal tensioning device, which includes a U-shaped frame and a diagonal telescopic rod mounted on a single chain plate of the flexible conveyor chain. One end of the diagonal telescopic rod is connected to the U-shaped frame via a pivot, and the other end is connected to a clamping ring via a pin.

[0022] Furthermore, both ends of the rack located in the uphill and downhill pipes maintain a distance from the pipe opening.

[0023] Compared with the prior art, the beneficial effects of the present invention are: the desizing device of the present invention is a circulating cleaning pipe, which is equipped with a circulating flexible conveyor chain plate. Denim garments enter from one end of the pipe, and the flexible conveyor chain plate and clamps are used to sequentially desizing and cleaning the garments with clean water, and then take them out. Putting in from one end and taking out from the other end do not affect each other, so that the entire desizing device can continuously feed and discharge without stopping.

[0024] The clamp in this invention can fix denim clothing in the same way as a clothing display mannequin. It is used in conjunction with a carrier and a drive mechanism to keep the denim clothing in an unfolded state and rotate during movement. This can effectively allow the inside and outside of the clothing to come into full contact with the desizing liquid, water, etc., and can prevent the clothes from getting mixed together and wrinkling.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] This invention provides a technical solution:

[0035] Please see Figures 1-7 A desizing device for denim garments before washing includes a circulating cleaning pipe and a desizing liquid source 6. A closed-loop flexible conveyor chain plate 14 is installed inside the circulating cleaning pipe. The chain, sprockets, etc. of the flexible conveyor chain plate 14 are all inside the circulating cleaning pipe. The drive module of the flexible conveyor chain plate 14 is outside the circulating cleaning pipe. The drive of the drive module passes through the pipe body, and the penetration is sealed with a shaft seal. The flexible conveyor chain plate 14 here is a known technology and will not be described in detail in this case.

[0036] In addition, the circulating cleaning pipe is equipped with a chain pressure bar to ensure full contact between the chain and the sprocket, and a chain plate support plate to support the chain plate. At the bends of the pipe, the pressure bar and the chain plate support plate have corresponding angles or curvatures.

[0037] The circulating cleaning pipeline includes a horizontal feeding pipe 2, a concave pipe 1, a horizontal cleaning pipe, an uphill pipe, a downhill pipe and a horizontal discharging pipe 12. The horizontal cleaning pipe includes a desizing pipe 4 and a draining pipe 8. The uphill pipe includes an uphill pipe 7 and the downhill pipe includes a downhill pipe 3.

[0038] The two openings of the concave pipe 1 are respectively connected to the horizontal feeding pipe 2 and the horizontal discharging pipe 12. Both the horizontal feeding pipe 2 and the horizontal discharging pipe 12 have openings. The outlet of the horizontal feeding pipe 2 is connected to the downhill pipe 3. The outlet of the downhill pipe 3 is connected to the desizing pipe 4. The outlet of the desizing pipe 4 is connected to the uphill pipe 7. The outlet of the uphill pipe 7 is connected to the draining pipe 8. It also includes a clean water source 13. The horizontal cleaning pipe also includes a clean water cleaning pipe 10. The uphill pipe also includes an uphill pipe 2 11. The downhill pipe also includes a downhill pipe 2 9. The outlet of the draining pipe 8 is connected to the downhill pipe 2 9. The outlet of the downhill pipe 2 9 is connected to the clean water cleaning pipe 10. The outlet of the clean water cleaning pipe 10 is connected to the uphill pipe 2 11. The outlet of the uphill pipe 2 11 is connected to the horizontal discharging pipe 12.

[0039] Of the above, the horizontal feeding pipe 2, the drain pipe 8, and the horizontal discharging pipe 12 are located at the highest positions, while the desizing pipe 4 and the clean water cleaning pipe 10 are located at the lowest positions, in order to ensure that the desizing liquid and clean water do not enter the horizontal feeding pipe 2, the drain pipe 8, and the horizontal discharging pipe 12.

[0040] Sewage pipes 5 are also installed at the bottom of the sunken end of the downhill pipe 2 9 and at the bottom of the clean water cleaning pipe 10. The clean water source 13 is connected to the clean water cleaning pipe 10 through the pipe.

[0041] In the above, all pipe connections are made using flange connections. Each pipe section is composed of several small, modular pipe sections, all of which are square. Each pipe section is equipped with a cap, which has a sealing structure to prevent water leakage.

[0042] The desizing liquid source 6 is connected to the desizing pipe 4 through a pipeline. The bottom of the desizing pipe 4 is equipped with a sewage pipe 5. The desizing liquid source 6 can also be a desizing liquid tank, desizing liquid kettle, etc. The desizing liquid is filled into the desizing pipe 4 by the pump body and the pipeline. The clean water source 13 can also be a clean water tank, clean water container, tap water valve, etc. The clean water is filled into the clean water cleaning pipe 10 by the pump body and the pipeline.

[0043] The degreasing pipe 4 can be filled first, and then the drain pipe 5 can be started to drain the degreasing liquid, and then new degreasing liquid can be injected; or the degreasing pipe 4 can be continuously injected into and continuously discharged from the degreasing liquid at the same time, and the same applies to the clean water cleaning pipe 10.

[0044] The sewage pipe 5 of the deslurry pipe 4 is connected to the special treatment equipment, and the sewage pipe 5 of the clean water cleaning pipe 10 is also connected to the special treatment equipment. These two special treatment devices are not technical means in this case and will not be described in detail here.

[0045] A clean water source 13 can also be connected to the uphill pipe 7 near the outlet to achieve pre-rinsing after deslurry removal.

[0046] Carriers 16 are installed at equal intervals on the flexible conveyor chain plate 14, and the carriers 16 movably carry garment clamps 15.

[0047] In the above description, the garment clamp 15 is initially located outside the pipe. First, the jeans are placed onto the garment clamp 15. Then, the carrier 16, installed on the flexible conveyor chain plate 14 at the inlet of the horizontal feed pipe 2, is placed in. After the first garment clamp 15 is placed in, the carrier 16 moves it forward at a slow speed. Then, the second garment clamp 15 is placed in, and so on. The garment clamp 15 follows the flexible conveyor chain plate 14 down the downhill pipe 3 and enters the desizing pipe 4. The desizing pipe 4 is pre-filled with... The garment clamp 15 is filled with desizing liquid, and the jeans on it come into full contact with the desizing liquid for desizing treatment. During the desizing treatment, the garment clamp 15 continuously follows the flexible conveyor chain plate 14. The forward speed is slow. When it comes out of the desizing pipe 4 and enters the uphill pipe 7, the desizing is just completed. After entering the uphill pipe 7, it enters the drain pipe 8. The jeans drain the remaining desizing liquid in the uphill pipe 7 and the drain pipe 8. The drained desizing liquid also enters the desizing pipe 4.

[0048] The garment clamp 15 then follows the flexible conveyor chain plate 14 into the downhill pipe 2 9, then into the clean water cleaning pipe 10 for clean water cleaning, and finally into the uphill pipe 2 11 and then into the horizontal discharge pipe 12, and is taken out from the carrier 16 along with the garment clamp 15.

[0049] After removal, subsequent processes are carried out. In this case, the main purpose of rinsing with water is to remove the residual desizing liquid from the jeans.

[0050] For the above, the carrier 16 includes a base 163 mounted on a single chain plate of the flexible conveyor chain plate 14, and a clamping ring 161 is mounted on the base 163;

[0051] The garment clamp 15 includes a sleeve 151, a large bearing 162 is installed on the outside of the sleeve 151, the large bearing 162 is located inside the clamping ring 161, and two trouser leg rods 154 are installed on one side of the sleeve 151.

[0052] The flexible conveyor chain plate 14 drives the carrier 16 and the garment clamp 15 through the horizontal feeding pipe 2, the horizontal cleaning pipe, the uphill pipe, the downhill pipe, the horizontal feeding pipe 12, and the concave pipe 1.

[0053] The sleeve 151 and the two leg inserts 154 form a denim mannequin. The waistband of the denim is fitted onto the sleeve 151, and the two leg inserts 154 are inserted into the two legs of the denim. The two leg inserts 154 are relatively short and do not need to be the same length as the legs. During the movement, water will enter the sleeve 151 from the front of the carrier 16 and then enter the two legs of the denim. This water flow will cause the denim to open up, so that the inside and outside of the denim can fully contact the desizing liquid and clean water.

[0054] When inserting the garment clamp 15, it is only necessary to insert the large bearing 162 outside the sleeve 151 into the clamping ring 161. In order to make it easier to insert the garment clamp 15, the clamping ring 161 includes two semi-circular rings 1610. One side of the two semi-circular rings 1610 is connected by a hinge 1611, and the other side of the two semi-circular rings 1610 has an extension. The two extensions are locked together by a hand-tightening screw.

[0055] Before inserting the garment clamp 15, first open the upper semicircular ring 1610, then lower the garment clamp 15 so that the large bearing 162 is placed inside the upper semicircular ring 1610. Then cover the upper semicircular ring 1610 and tighten the hand screw. In this way, the clamping ring 161 clamps the large bearing 162.

[0056] In addition, the carrier 16 also includes a drive device for rotating the garment clamp 15. The drive device includes a rack 17 installed in the horizontal cleaning pipe, the uphill pipe, and the downhill pipe respectively, a secondary bearing sleeved on the outside of the end of the sleeve 151 extending from the large bearing 162, and a gear ring 20 connected to the end of the sleeve 151 extending from the large bearing 162. A secondary sleeve 156 is sleeved on the secondary bearing. One end of the secondary sleeve 156 extends into the clamping ring 161. A vertical rod 19 is installed on the top of the secondary sleeve 156. A horizontal bar is installed on one side of the vertical rod 19. A small bearing is installed on one side of the horizontal bar. A shaft 21 passes through the small bearing. A gear 18 is connected to the top of the shaft 21. The gear 18 meshes with the rack 17. A bevel gear 22 is connected to the bottom of the shaft 21. The bevel gear 22 meshes with the gear ring 20.

[0057] The crossbar and small bearings are provided in multiple sets, and the bottom of the gear 18 is also equipped with a transverse bearing, which presses against the small bearing at the top.

[0058] The clamping ring 161 clamps the large bearing 162 and the secondary sleeve 156 simultaneously, which means that the large bearing 162 and the secondary sleeve 156 are locked at the same time.

[0059] Under normal circumstances, each of the downhill pipe 1 3, uphill pipe 1 7, drain pipe 8, clean water washing pipe 10, and uphill pipe 2 11 is equipped with a rack 17. The horizontal feed pipe 12 is also equipped with a rack 17. However, the rack 17 stops when it is close to the opening on the horizontal feed pipe 12. Both ends of the rack 17 in the uphill and downhill pipes are kept at a distance from the pipe opening. The purpose is to allow the gear 18 to contact the rack 17 after the carrier 16 and the garment clamp 15 are stabilized.

[0060] As the flexible conveyor chain plate 14 moves forward, the gear 18 meshes with the rack 17, the gear 18 rolls on the rack 17, driving the shaft 21 to rotate, the shaft 21 drives the bevel gear 22 to rotate, the bevel gear 22 drives the gear ring 20 to rotate, and then the sleeve 151 drives the jeans to rotate along the large bearing 162.

[0061] Because the jeans are open, they come into full contact with the desizing liquid, so the rotation speed of the sleeve 151 does not need to be high.

[0062] The sleeve 151 rotates to dehydrate the jeans after they enter the drain pipe 8 and the horizontal discharge pipe 12.

[0063] The length of the horizontal feed tube 12 can be set to be relatively long, allowing the sleeve 151 to rotate continuously within the horizontal feed tube 12 for a period of time.

[0064] In addition, for the stability of the carrier 16, the carrier 16 also includes a diagonal pull device. The diagonal pull device pulls the carrier 16 back from the opposite side of the clamp to ensure the stability of the carrier 16 and the garment clamp 15. The diagonal pull device includes a U-shaped frame 164 and a diagonal telescopic rod 165 mounted on a single chain plate of the flexible conveyor chain plate 14. One end of the diagonal telescopic rod 165 is connected to the U-shaped frame 164 through a pivot, and the other end is connected to the clamping ring 161 through a pin.

[0065] A chain plate separates the U-shaped frame 164 and the base 163, meaning that the U-shaped frame 164 and the base 163 are not mounted on the same chain plate.

[0066] The inclined telescopic rod 165 includes an inner telescopic rod and an outer telescopic rod. One end of the inner telescopic rod is slidably sleeved inside the outer telescopic rod, and a spring 166 is installed inside the outer telescopic rod. The two ends of the spring 166 are respectively connected to one end of the inner telescopic rod and the inner bottom of the outer telescopic rod.

[0067] The inclined telescopic rod 165 can elastically expand and contract to adapt to the bends in the pipeline. When bending, the inclined telescopic rod 165 can elastically expand and contract and can adapt to the swing by using the pivot and pin.

[0068] The inner telescopic rod has an expanded diameter at one end inside the outer telescopic rod, which slides within the inner cavity of the outer telescopic rod. The outer telescopic rod has a reduced diameter at the other end near the outlet, which prevents the inner telescopic rod from slipping out.

[0069] Among them, the sleeve 151 has a number of filter holes 153 on the other end extending from the large bearing 162.

[0070] The sleeve 151 has a hook 152 installed on the outer wall of the other end extending from the large bearing 162. When the waistband of the jeans is put on the sleeve 151, the hook 152 can be used to hook the waistband.

[0071] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
