Description

Technical Field

[0001] The invention relates to the technical field of garment processing, and in particular discloses a wool sweater finished product shrinking machine. Background Art

[0002] In the last process of wool sweater production, the finished wool sweater needs to be subjected to shrinkage treatment to make the sweater tight, short, elastic and warm. At present, the shrinkage treatment of wool sweaters in the industry is usually carried out by a drum shrinking machine. Its working principle is similar to that of a drum washing machine. The shrinkage liquid is injected into the inside, and then the sweater is turned over by the drum and fully contacted with the shrinkage liquid to achieve the shrinkage effect.

[0003] The invention patent with application number 202410702029.8 discloses a shrinking machine for wool sweaters, including a shell, a rotating drum for holding wool sweaters, a liquid inlet assembly and an anti-blocking assembly. The rotating drum is rotatably connected to the shell, and a plurality of drainage holes are provided in the rotating drum. The liquid inlet assembly is used to spray the mixed liquid into the rotating drum. The anti-blocking assembly includes a plurality of cleaning parts and a driving part. The plurality of cleaning parts correspond to the plurality of drainage holes one by one. The cleaning parts include two transmission belts, two gears and a bidirectional screw. The two transmission belts are distributed along the axis of the rotating drum. The gears are arranged on the rotating axis and the two gears are respectively engaged with the opposite threaded sections of the bidirectional screw. The driving part is used to drive the bidirectional screw to rotate. The shrinking machine disclosed in the patent can perform online dredging of the drainage holes during the rotation of the rotating drum through the design of the cleaning parts on the drainage holes, so as to prevent the broken hair and miscellaneous hair falling from the wool sweaters from clogging the drainage holes, which has certain positive effects. However, when the wool sweater is subjected to the milling treatment, the milling machine can only generate mechanical external force through the friction and falling impact between the wool sweaters, which makes the mechanical external force in the milling process insufficient, resulting in poor milling effect. It is necessary to extend the working time of the milling machine to ensure the treatment effect. In addition, during the rotation of the drum, the milling liquid will gather at the bottom and cannot fully contact with the upper wool sweater, which to a certain extent also affects the efficiency and uniformity of the milling treatment of the entire wool sweater. Therefore, in view of the above-mentioned deficiencies of the existing milling machines for wool sweaters, the present application proposes a finished wool sweater milling machine based on the existing milling machine, which is technically upgraded and modified to solve the above-mentioned technical problems and deficiencies of the existing drum milling machine. Summary of the invention

[0004] The present invention aims to provide a finished wool sweater shrinking machine, so as to realize the continuous generation of stronger external mechanical force on the wool sweater during the shrinking process, thereby accelerating the shrinking efficiency of the wool sweater, and at the same time allowing the shrinking liquid to continuously and fully contact with the upper and lower layers of the wool sweater, thereby ensuring the shrinking effect of the wool sweater.

[0005] The present invention is achieved through the following technical solutions: A wool sweater finished product shrinking machine, comprising a bottom box and an outer cylinder, wherein an inner cylinder is concentrically arranged in the outer cylinder, the outer cylinder is arranged at the upper end of the bottom box, and a water outlet connected to the inner cavity of the bottom box is opened at the bottom of the outer cylinder, an arc-shaped sealing plate is arranged in the water outlet, and a cover plate for sealing the outer cylinder and the front end of the inner cylinder is arranged at the front end of the outer cylinder; A plurality of rotating rods are evenly arranged in the circumference of the inner cylinder, and an extrusion cam column spaced from the inner wall of the inner cylinder is eccentrically arranged on the rotating rod, a small gear is connected to the rear end of the rotating rod extending out of the inner cylinder, a large gear meshing with all the small gears is fixedly arranged in the outer cylinder, a hollow rotating shaft passing through the large gear is arranged at the rear end of the inner cylinder, and a power assembly for driving the hollow rotating shaft is arranged on the outer cylinder, an infusion tube is passed through the hollow rotating shaft, an infusion pump is connected to the end of the infusion tube, and a spray head is connected to the lower end of the infusion tube located in the inner cylinder; A plurality of water-permeable holes arranged in rows are evenly arranged on the circumferential surface of the inner cylinder, and a wiper plate is arranged on the outer circumferential surface of the inner cylinder between two adjacent groups of water-permeable holes, and the outer end of the wiper plate is arranged in contact with the inner wall of the outer cylinder.

[0006] During the operation of the wool sweater finished product shrinking machine disclosed in the present invention, the rotation of the inner cylinder causes the extrusion cam column arranged inside to perform planetary motion synchronously, and the meshing transmission between the large gear and the small gear can continuously rotate around the extrusion cam column. During the automatic operation of the extrusion cam column, the distance between the extrusion cam column and the inner wall of the inner cylinder can be continuously changed due to its eccentric structural design, so the wool sweater attached to the inner wall of the inner cylinder can be continuously squeezed by the extrusion cam column during the sliding process, thereby enhancing the mechanical external force received by the wool sweater during the shrinking process, so that the shrinking process speed is faster.

[0007] At the same time, due to the action of the scraper, the shrinking liquid originally gathered at the bottom of the outer cylinder can be scraped up and lifted upward during the rotation of the inner cylinder. When it is lifted to a certain height, the shrinking liquid is sprinkled into the interior of the inner cylinder through the water permeable holes and poured on the wool sweater on the upper layer, so that the wool sweater can be fully in contact with the shrinking liquid, thereby ensuring the shrinking effect of the wool sweater.

[0008] After the shrinking treatment of the wool sweater is completed, the arc-shaped sealing plate is opened to discharge the shrinking liquid in the outer cylinder into the bottom box, and then the inner cylinder is continued to be driven to rotate. During the rotation of the inner cylinder, on the one hand, the water adsorbed on the wool sweater can be thrown out by the centrifugal effect, and on the other hand, the extrusion effect of the extrusion cam column can be utilized to fully squeeze out the adsorbed water on the wool sweater, so that the wool sweater can be quickly dehydrated after the shrinking treatment.

[0011] The above is a specific installation and driving method between the inner cylinder and the outer cylinder, so that the inner cylinder can stably rotate around the central axis of the outer cylinder under the action of the driving motor, and the shrinkage liquid can be avoided from spilling to the front and rear ends of the outer cylinder as much as possible.

[0012] As a further configuration of the above solution, each row of the water-permeable holes is arranged at equal intervals along the axial direction, and the water-permeable holes are in an arc shape with a certain length.

[0014] As a further configuration of the above scheme, a driven pulley is arranged at the rear end of the cleaning rotating rod, a driving pulley is arranged on the hollow rotating shaft, and a transmission belt is arranged between the driving pulley and the driven pulley.

[0015] The present invention further designs the above-mentioned scheme, specifically designs the water permeable hole structure, and utilizes the driving action of the cleaning rotating rod to enable the broken hair picking strip to extend into the water permeable hole, thereby cleaning the broken hair and miscellaneous hair clogging the water permeable hole online, avoiding the broken hair and miscellaneous hair falling from the wool sweater after long-term operation to cause clogging of the water permeable hole, thereby ensuring the stable operation of the entire equipment.

[0016] As a further configuration of the above scheme, the liquid inlet end of the infusion pump is connected to a three-way valve, one end of the three-way valve is connected to the source of the shrinkage solution, and the other end is connected to the lower end of the bottom box.

[0017] As a further configuration of the above scheme, a filter layer is provided in the bottom box, and the three-way valve and the drain are respectively located on both sides of the filter layer.

[0018] The present invention can also reuse the shrinkage liquid recovered in the bottom box through the above-mentioned structural design, and filter and retain the recycled shrinkage liquid through the filter layer before pumping it out, so as to avoid clogging of the spray head by broken hair and miscellaneous hair, thereby ensuring the stable operation of the spray system.

[0019] As a further configuration of the above scheme, the arc-shaped sealing plate is rotatably connected to one end of the drain, a telescopic driving member for driving the arc-shaped sealing plate to rotate is provided in the bottom box, the cover plate is rotatably connected to the front end opening of the outer cylinder, and a handle is provided on the outer surface of the cover plate.

DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Figures 1 to 9 , and describes the application in detail with reference to embodiments. Example 1

[0029] Embodiment 1 discloses a wool sweater finished product shrinking machine, Figures 1 to 3 The main body of the shrinking machine includes a bottom box 1 and an outer cylinder 2. The outer cylinder 2 is fixedly arranged at the upper end of the bottom box 1, and the lower half of the outer cylinder 2 is extended into the inner cavity of the bottom box 1. A cover plate 3 is rotatably connected to the front opening of the outer cylinder 2 through a hinge, and a handle 301 is arranged on the cover plate 3 for convenient operation.

[0030] A water outlet is provided at the lower end of the outer cylinder 2, and an arc-shaped sealing plate 201 is rotatably connected to one end of the water outlet. Meanwhile, a telescopic driving member 4 is rotatably installed on the upper end of the inner wall of the bottom box 1, and the telescopic end of the telescopic driving member 4 is connected to the outer wall of the arc-shaped sealing plate 201. The telescopic driving member 4 can be a hydraulic telescopic rod or an electric push rod, so that the arc-shaped sealing plate 201 opens or closes the water outlet at the lower end of the outer cylinder 2 when the telescopic driving member 4 is extended or shortened.

[0031] Reference Figure 3 , Attachment Figure 4 and attached Figure 7 , an annular plate 202 is radially extended inwardly at both the front and rear ends of the inner wall of the outer cylinder 2, and the water outlet is opened at the lower end of the outer cylinder 2 between the two annular plates 202. A bearing ring 5 is arranged in the inner ring of each annular plate 202, and then an inner cylinder 6 is rotatably connected between the two bearing rings 5. The rear end of the inner cylinder 6 is sealed, and the front end is provided with a feeding circular opening adapted to the cover plate 3.

[0032] Reference Figures 4 to 6 , 2 to 4 rotating rods 7 are arranged in a circular array in the inner cylinder 6, and there is still a radial distance of about 8 to 10 cm between the rotating rods 7 and the inner wall of the inner cylinder 6, and then an extrusion cam column 8 is arranged on each rotating rod 7. And the extrusion cam column 8 is eccentrically arranged, so that during the rotation of the rotating rod 7, the radial distance between the extrusion cam column 8 and the inner wall of the inner cylinder 6 can be continuously changed in 3 to 6 cm, thereby providing corresponding extrusion force to the finished wool sweater. A small gear 9 is arranged at the end of each rotating rod 7 extending out of the rear end face of the inner cylinder 6, and then a hollow rotating shaft 10 is arranged at the center of the rear end face of the inner cylinder 6, and a large gear 11 that meshes with all the small gears 9 at the same time is sleeved on the hollow rotating shaft 10, and the large gear 11 is fixedly connected to the rear end face of the outer cylinder 2. During the rotation of the inner cylinder 6, through the meshing transmission between the small gear 9 and the large gear 11, not only the small gear 9 can make a planetary motion, but also it can occur automatically, so that the extrusion cam column 8 in the inner cylinder 6 rotates eccentrically. In addition, in order to drive the inner cylinder 6 to rotate stably around its own central axis, a driven gear 12 is fixedly arranged on the outer circumferential surface of the hollow rotating shaft 10, and then a driving motor 13 is arranged on the rear end surface of the outer cylinder 2, and a driving gear 14 meshing with the driven gear 12 is arranged at the inner end of the motor shaft of the driving motor 13.

[0033] A plurality of groups of water-permeable holes 601 are evenly arranged on the outer circumferential surface of the inner cylinder 6, and each group of water-permeable holes 601 is arranged in 1 to 3 rows. Each row of water-permeable holes 601 is arranged on the outer circumferential surface of the inner cylinder 6 at equal intervals along the axial direction, and the specific shape of the water-permeable holes 601 is an arc shape with a certain length. A wiper 15 is arranged on the outer circumferential surface of the inner cylinder 6 between each two adjacent groups of water-permeable holes 601, and a certain distance is spaced between the wiper 15 and the corresponding water-permeable holes 601, and the radial outer end of the wiper 15 is in contact with the inner wall of the outer cylinder 2. The wiper 15 can scrape the shrinkage solution originally gathered at the lower end of the outer cylinder 2 upwards during the rotation of the inner cylinder 6, and then after rotating and lifting to a certain height, it falls into the upper end of the sweater in the inner cylinder 6 through the water-permeable holes 601.

[0034] Reference Figure 2 , Attachment Figure 3 and attached Figure 4 An infusion pump 16 is arranged at the rear side of the bottom box 1, and an L-shaped infusion tube 17 is connected to the liquid outlet of the infusion pump 16, and the horizontal end of the infusion tube 17 passes through the hollow rotating shaft 10 and extends into the inner cylinder 6, and then a row of spray heads 18 are arranged on the lower surface of the infusion tube 17 in the inner cylinder 6. A three-way valve 19 is connected to the liquid inlet end of the infusion pump 16, one end of the three-way valve 19 is connected to the source of the shrinkage solution, and the other end is connected to one side of the lower end of the bottom box 1. In addition, in order to prevent the broken hair in the second-use shrinkage solution from entering the spray head 18 and causing blockage, a vertically arranged filter layer 20 is also arranged in the bottom box 1.

[0035] During the operation of the wool sweater finished product shrinking machine disclosed in the present embodiment 1, the material is put into the inner cylinder 6, and then the cover plate 3 is closed to seal the front end of the outer cylinder 2 and the front end of the outer cylinder 2. Then, the infusion pump 16 is started to pump the shrinking solution, and spray it downward through the infusion pipe 17 and the spray head 18, so that the shrinking solution is evenly sprinkled on the wool sweater in the inner cylinder 6 to make it wet.

[0036] Next, the driving motor 13 is started, and the inner cylinder 6 is made to rotate concentrically inside the outer cylinder 2 under the meshing transmission of the driving gear 14 and the driven gear 12, and the shrinkage solution is continuously sprayed through the spray head 18 until the shrinkage solution immerses the sweater at the lower end. During the rotation of the outer cylinder 2, the multiple rotating rods 7 and the small gear 9 perform planetary motion synchronously, and because the large gear 11 is relatively fixed, the multiple extrusion cam columns 8 arranged in the inner cylinder 6 are caused to rotate synchronously through the action between the large gear 11 and the small gear 9. During the rotation of the extrusion cam column 8, due to the eccentric design of the extrusion cam column 8, the distance between the extrusion cam column 8 and the inner wall of the inner cylinder 6 can be continuously changed, so that the sweater is continuously squeezed by the extrusion cam column 8 while sliding downward along the inner cylinder 6. Combined with the immersion treatment of the shrinkage solution, the shrinkage treatment efficiency of the sweater can be accelerated.

[0037] In addition, during the rotation of the inner cylinder 6, the wiper plate 15 can scrape up the shrinkage solution accumulated at the bottom of the inner cylinder 6, and then rotate and lift it to a certain height before falling through the water-permeable hole 601 to the upper end of the wool sweater in the inner cylinder 6 under the action of gravity, so that the wool sweater inside can be fully in contact with the shrinkage solution, which can improve the shrinkage uniformity of the wool sweater.

[0038] Finally, after the wool sweater is fully shrunken, the drain port at the lower end of the outer cylinder 2 is opened by the telescopic driving member 4, so that the excess fully shrinking solution is discharged to the lower end of the inner cavity of the bottom box 1. Then, during the continuous rotation of the inner cylinder 6, the solution adsorbed by the wool sweater is thrown out by the centrifugal force, and on the other hand, the squeezing effect of the squeezing cam column 8 can accelerate the squeezing of the solution on the wool sweater, so that the wool sweater can be quickly dehydrated. After the dehydration is completed, the cover plate 3 can be opened to take it out. Example 2

[0039] Example 2 discloses a finished wool sweater shrinking machine that is further improved based on the technical solution in Example 1, and the similarities between it and Example 1 are not described again.

[0040] Reference Figure 3 , Attachment Figure 4 and attached Fig. 9 In the second embodiment, a cleaning port is provided on one side of the upper end of the outer cylinder 2, and a shield 21 is provided on the outer circumferential surface of the outer cylinder 2 to cover the outer side of the cleaning port. A cleaning rotating rod 22 is provided in the annular gap between the outer cylinder 2 and the inner cylinder 6, and the cleaning rotating rod 22 is rotatably connected to the two ring plates 202. At the same time, a driven pulley 23 is connected to the rear end of the ring plate 202 after the cleaning rotating rod 22 extends out, and then a driving pulley 24 is provided on the hollow rotating shaft 10, and a transmission belt 25 is provided between the driving pulley 24 and the driven pulley 23.

[0041] One or two rows of hair-splitting strips 26 are arranged on the cleaning rotating rod 22, and each row of hair-splitting strips 26 is aligned with each row of water-permeable holes 601 on the inner cylinder 6. When the water-permeable holes 601 are rotated to the cleaning opening position, the row of hair-splitting strips 26 on the cleaning rotating rod 22 can extend into the water-permeable holes 601 to remove the hairs blocked in the water-permeable holes 601. Finally, a row of cleaning combing rods 27 are fixedly connected to the outer wall of the outer cylinder 2 below the shield 21, and the cleaning combing rods 27 and the hair-splitting strips 26 are mutually offset, and a material guide chute 101 is provided on the upper surface of the bottom box 1 below the cleaning combing rods 27.

[0042] Through the above-mentioned improved design, the cleaning rod 22 of the present embodiment 2 can rotate synchronously during the rotation of the inner cylinder 6, and through the design of a reasonable transmission coefficient, when the water permeable hole 601 on the inner cylinder 6 rotates to the debris cleaning port, the broken hair strip 26 on the cleaning rod 22 can extend therein, thereby picking up the broken hair and scattered hair originally blocked in the water permeable hole 601; and when the wiper blade 15 rotates to the debris cleaning port, the broken hair strip 26 on the cleaning rod 22 is received in the baffle cover 21 and does not affect it.

[0043] When the picked up broken hair and miscellaneous hair rotate with the cleaning rotating rod 22 to the position of the cleaning combing rod 27, they can be combed out by the cleaning combing rod 27 and finally fall on the guide chute 101 for discharge and collection. The whole design can clean the miscellaneous hair and broken hair in the water permeable hole 601 online to avoid clogging the water permeable hole 601.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
