DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] Reference Figure 1-Figure 5 The present invention provides a printing and dyeing device for towel processing, comprising:

[0041] The printing and dyeing tank 1 has a feed roller 2 and a discharge roller 3 connected to the top of both sides along the width direction;

[0042] The nip roller 4 is arranged in the printing and dyeing pool 1. A driving assembly is arranged on the printing and dyeing pool 1. The driving end of the driving assembly is connected to the nip roller 4 so that the nip roller 4 reciprocates in the vertical direction.

[0043] The filter screen 5 is arranged in the printing and dyeing tank 1, and the lowest end of the nip roller 4 is in pressure contact with the top surface of the filter screen 5;

[0044] The filter tank 6 is fixedly connected to one side of the printing and dyeing tank 1. The first discharge hole 7 and the second discharge hole 8 are respectively opened on the side of the printing and dyeing tank 1 close to the filter tank 6. The projection of the first discharge hole 7 along the horizontal direction is arranged at the bottom of the printing and dyeing tank 1, and the projection of the second discharge hole 8 along the horizontal direction is arranged at the top of the filter tank 6;

[0045] The filter box 9 is configured such that the liquid inlet end is connected to the filter tank 6 , and the liquid outlet end of the filter box 9 is connected to the printing and dyeing tank 1 .

[0046] The present invention supports the towel fabric by means of a feed roller 2 and a discharge roller 3, and the towel fabric is transported along the width direction of the printing and dyeing tank 1, and a pressing roller 4 is used to squeeze the towel fabric along the vertical direction. A driving component is provided on the printing and dyeing tank 1, and the driving component drives the pressing roller 4 to reciprocate and rise and fall, and the pressing roller 4 cooperates with the filter screen 5 to squeeze the towel fabric, so that the towel fabric repeatedly absorbs and releases the printing and dyeing liquid, thereby enhancing the degree of printing and dyeing sufficiency, and the lint in the towel fabric can be effectively discharged.

[0047] In addition, as the fluff content in the printing and dyeing pool 1 gradually increases, the printing and dyeing liquid is discharged into the filter tank 6 through the first discharge hole 7 and the second discharge hole 8. Since the fluff can float on the liquid surface of the printing and dyeing pool 1 and mix in the printing and dyeing pool 1 respectively, the printing and dyeing liquid is continuously stirred in the printing and dyeing pool 1 by using the pressing roller 4, so that the fluff mixed in the printing and dyeing pool 1 can be statically settled after passing through the first discharge hole 7 into the filter tank 6, thereby being separated from the printing and dyeing liquid in the printing and dyeing pool 1, and the floating fluff directly overflows into the filter tank 6 through the second discharge hole 8. The top height of the filter tank 6 is lower than the liquid level of the printing and dyeing liquid in the printing and dyeing pool 1, so that the floating fluff is separated from the printing and dyeing pool 1, and the separation liquid in the filter tank 6 is filtered in combination with the filter box 9, so as to purify the printing and dyeing liquid in the printing and dyeing pool 1, and effectively improve the quality of printing and dyeing of towel fabrics.

[0048] Specifically, since the second discharge hole 8 is connected to the filter tank 6, the liquid level in the filter tank 6 is the same as the liquid level in the printing and dyeing tank 1, and the first discharge hole 7 is located between the printing and dyeing tank 1 and the filter tank 6 containing the same medium, the pressing roller 4 is used to stir the printing and dyeing liquid, so that the fluff mixed in the printing and dyeing liquid gradually flows into the filter tank 6 from the first discharge hole 7 and is deposited in the relatively gentle filter tank 6, thereby achieving the separation of the mixed fluff.

[0049] It can be understood that the towel fabric is transported by a winding mechanism and an unwinding mechanism on both sides along the width direction of the printing and dyeing tank 1, which is a conventional technology and will not be described in detail.

[0050] Furthermore, it also includes:

[0051] Two pairs of supports 10 are arranged opposite to each other on both sides of the top of the printing and dyeing pool 1 along the width direction. A rotation interval is provided between any pair of supports 10, and the feed roller 2 and the discharge roller 3 are respectively connected to the two rotation intervals;

[0052] The elastic member is arranged on the support 10, and the elastic end of the elastic member is connected to the adjacent feed roller 2 or discharge roller 3, so that the feed roller 2 or discharge roller 3 has an elastic tendency to be lifted vertically upward.

[0053] By utilizing the rotation range defined between a pair of supports 10, two pairs of supports 10 are respectively arranged corresponding to the feed roller 2 and the discharge roller 3. The supports 10 are fixedly connected to the top of the printing and dyeing pool 1 to stably support the feed roller 2 and the discharge roller 3. Elastic parts are arranged on the supports 10 to make the discharge roller 3 and the feed roller 2 have an elastic tendency in the vertical upward direction, thereby forming an elastic force opposite to that of the pressing roller 4. When the pressing roller 4 presses down the towel fabric, the discharge roller 3 and the feed roller 2 can better cooperate to unfold the towel fabric, thereby enhancing the printing and dyeing effect.

[0054] Furthermore, the elastic member comprises:

[0055] Connecting rod 11, a groove is provided on one side of the support 10 close to the printing and dyeing pool 1, a fixing rod 12 is fixedly connected in the groove, a sleeve 13 is provided on the outer surface of the fixing rod 12, one end of the connecting rod 11 is fixedly connected to the outer side wall of the sleeve 13, the other end of the connecting rod 11 extends out of the groove and is fixedly connected to a support rod 15, both ends of the support rod 15 are respectively fixedly connected to the two connecting rods 11, and the discharging roller 3 or the feeding roller 2 is sleeved on the connecting rod 11 and transferred to the connecting rod 11;

[0056] The torsion spring 14 is wound around the fixing rod 12 , and two ends of the torsion spring 14 are fixedly connected to the fixing rod 12 and the sleeve 13 respectively.

[0057] The sleeve 13 and the fixed rod 12 are elastically connected by the torsion spring 14, and the connecting rod 11 is fixedly connected to the outer wall of the sleeve 13, so that the connecting rod 11 has an elastic tendency to rotate relative to the fixed rod 12. The connecting rod 11 is used to fix the support rod 15, and the discharge roller 3 and the feed roller 2 are respectively sleeved and connected to the two support rods 15, forming an elastic rotation effect along the opposite sides of the printing and dyeing pool 1, thereby realizing the stretching of the towel fabric.

[0058] Furthermore, the driving component includes:

[0059] The driving motor 16 is fixedly connected to one side of the outer wall of the printing and dyeing pool 1. The output shaft of the driving motor 16 is fixedly connected to a turntable 17. The turntable 17 is connected above the printing and dyeing pool 1. The turntable 17 is fixedly connected to an eccentric shaft 18 on one side close to the printing and dyeing pool 1. A collar 19 is connected to the eccentric shaft 18.

[0060] One end of the transmission rod 20 is fixed to the outer wall of the collar 19 , and the other end of the transmission rod 20 is hinged to a limit rod 21 , which is slidably connected to the printing and dyeing pool 1 along the vertical direction, and the bottom end of the transmission rod 20 is fixed to one end of the pressing roller 4 .

[0061] The driving motor 16 is used to drive the turntable 17 to rotate, and the eccentric shaft 18 is fixed on the turntable 17 and rotates synchronously with the turntable 17. The ring 19 mounted on the eccentric shaft 18 is fixedly connected to the transmission rod 20. When the turntable 17 rotates cyclically, the transmission rod 20 drives the limit rod 21 to reciprocate and rise and fall in the vertical direction.

[0062] Furthermore, it also includes:

[0063] The limiting seat 22 is fixedly connected to the inner wall of the printing and dyeing tank 1. The limiting seat 22 is provided with a limiting groove in the vertical direction, and the limiting rod 21 is slidably connected in the limiting groove;

[0064] The first suspension chain 23 has two ends fixedly connected to the bottom end of the transmission rod 20 and the top end of the nip roller 4 respectively;

[0065] The second hanging chain 24 is fixedly connected to the side of the top of the nip roller 4 away from the first hanging chain 23 . A hook 25 is fixedly connected to the side of the inner wall of the printing and dyeing pool 1 close to the second hanging chain 24 . The top of the second hanging chain 24 is fixed to the hook 25 .

[0066] The limiting rod 21 is limited and stabilized by the limiting seat 22, so that the first hanging chain 23 drives the pressing roller 4 to rise and fall in the vertical direction, and the other end of the pressing roller 4 is connected to the inner wall of the printing and dyeing pool 1 through the second hanging chain 24, and the second hanging chain 24 is fixed by the hook 25. The first hanging chain 23 and the second hanging chain 24 can fix the pressing roller 4 while ensuring the connection between the transmission rod 20 and the pressing roller 4 during the lifting and lowering of the transmission rod 20, so that the end of the pressing roller 4 close to the first hanging chain 23 can be lifted and lowered in the vertical direction to repeatedly squeeze the towel fabric, thereby promoting the contact between the printing and dyeing liquid and the towel fabric.

[0067] Furthermore, the length of the first hanging chain 23 is smaller than that of the second hanging chain 24 , and when the limiting rod 21 slides to the lowest end, the two ends of the pressing roller 4 are distributed in the horizontal direction.

[0068] By lifting and lowering the limiting rod 21 and pulling the first hanging chain 23, the first hanging chain 23 and the second hanging chain 24 are used to fix the pressing roller 4, and at the same time, the angle produced by the rotation and lifting of the pressing roller 4 can be adapted to enhance the coordination effect between the limiting rod 21 and the pressing roller 4.

[0069] Furthermore, a pair of racks 26 are fixedly connected in the printing and dyeing pool 1 along the length direction, the two ends of the filter screen 5 are respectively sleeved on the pair of racks 26, and the projection of the nip roller 4 along the vertical direction is arranged between the pair of racks 26.

[0070] The filter screen 5 is supported by the frame rod 26. When the nip roller 4 is pressed down, the bottom end of the nip roller 4 contacts the filter screen 5 and squeezes the towel fabric between the nip roller 4 and the filter screen 5, causing the printing and dyeing liquid in the towel fabric to precipitate. At the same time, when the nip roller 4 is lifted, new printing and dyeing liquid is absorbed, thereby enhancing the degree of printing and dyeing.

[0071] Furthermore, the liquid level in the printing and dyeing pool 1 does not exceed the horizontal height of the second discharge hole 8 , and the height of the inner wall of the bottom end of the filter pool 6 is lower than the horizontal height of the first discharge hole 7 .

[0072] In the present technical scheme, the liquid level of the printing and dyeing pool 1 is controlled below the second discharge hole 8. As the liquid level gradually increases, the fluff floating on the top surface of the printing and dyeing liquid can overflow from the second discharge hole 8 out of the printing and dyeing pool 1 and be collected by the filter 6. The inner wall height of the bottom end of the filter 6 is lower than the first discharge hole 7, so that the bottom of the filter 6 is connected with the printing and dyeing pool 1. As the pressing roller 4 continuously rises and falls to stir the printing and dyeing liquid, the fluff mixed in the printing and dyeing liquid can move along the direction of the filter 6 with a small stirring amplitude and settle at the bottom of the filter 6, thereby separating the fluff mixed in the printing and dyeing liquid and improving the printing and dyeing quality in the printing and dyeing pool 1.

[0073] Furthermore, a plurality of filter layers 27 are arranged vertically downward in the filter box 9. The top of the filter box 9 is connected to the filter tank 6 through the liquid inlet pipe 28. The bottom side of the filter box 9 is connected to the printing and dyeing tank 1 through the liquid outlet pipe 29. Pumps 30 are installed on the liquid outlet pipe 29 and the liquid inlet pipe 28.

[0074] The filter layer 27 is paved with common filter cotton, activated carbon and other materials, which are conventional technologies and will not be described in detail.

[0075] Specifically, the bottom end of the liquid inlet pipe 28 extends into the filter tank 6 and is arranged horizontally between the first discharge hole 7 and the second discharge hole 8. The printing and dyeing liquid in the filter tank 6 is sucked by a pump 30 and passed into the filter box 9, filtered through a plurality of filter layers 27, and finally the filtered printing and dyeing liquid is passed into the printing and dyeing tank 1 to complete the purification of the printing and dyeing liquid.

[0076] Furthermore, the cross-sections of the discharge roller 3 and the feed roller 2 are both I-shaped structures.

[0077] By arranging the discharge roller 3 and the feed roller 2 into an I-shaped structure, the structure forms a retaining edge structure along both sides, thereby improving the conveying stability of the towel fabric.

[0078] The working principle of the printing and dyeing device for towel processing of the present invention:

[0079] The towel fabric is conveyed along the width direction of the printing and dyeing pool 1, and is laid along the top of the feed roller 2 to the bottom of the nip roller 4 and then to the top of the discharge roller 3. The drive motor 16 is started to rotate the turntable 17, and the turntable 17 drives one end of the nip roller 4 to reciprocate and rise and fall through the transmission rod 20 and the limit rod 21. The nip roller 4 is supported by the filter screen 5. As the nip roller 4 moves, the nip roller 4 squeezes the towel fabric to repeatedly absorb and squeeze out the printing and dyeing liquid.

[0080] In addition, the pressing roller 4 stirs the printing and dyeing liquid in the printing and dyeing pool 1. Since the printing and dyeing pool 1 is connected to the filter pool 6, and the printing and dyeing liquid in the filter pool 6 and the printing and dyeing pool 1 are all submerged in the first discharge hole 7, and the top surface of the liquid surface in the filter pool 6 is located below the second discharge hole 8, as the printing and dyeing liquid in the printing and dyeing pool 1 is stirred, the fluff mixed in the printing and dyeing liquid enters the filter pool 6 through the first discharge hole 7. The bottom end height of the filter pool 6 is lower than the first discharge hole 7, so that the mixed fluff is precipitated and separated, and the fluff floating on the top surface of the printing and dyeing liquid overflows into the filter pool 6 through the second discharge hole 8, and the height difference prevents the floating fluff from flowing back into the printing and dyeing pool 1, thereby realizing the synchronous separation of the mixed fluff and the floating fluff, and effectively improving the printing and dyeing quality of the printing and dyeing liquid in the printing and dyeing pool 1. In addition, the printing and dyeing liquid in the filter pool 6 is suction filtered in combination with the filter box 9 to remove the separated fluff.

[0081] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0082] The embodiments described above are only descriptions of the preferred modes of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
