Description

Technical Field

[0001] The invention relates to the technical field of cloth rinsing, and in particular discloses a linen rinsing device. Background Art

[0002] Linen is a natural fabric made of flax fibers. It is breathable, moisture-absorbent, antibacterial and wear-resistant. It is often used in the production of summer clothing, furniture and other fields. During the deep processing of linen fabrics, the linen fabrics need to be rinsed. On the one hand, it is used to remove some natural impurities, grease and dyes remaining on the surface. On the other hand, it can soften the fibers, making the linen fabric feel softer and more comfortable, and is conducive to the subsequent dyeing process.

[0003] The equipment used for rinsing fabrics on the market mainly consists of a cleaning tank + two rows of guide rollers in an upper and lower row. During the rinsing process, the cleaning tank is filled with rinsing liquid, and then the fabric is pulled and sequentially staggered up and down through the guide rollers, so that the fabric is reciprocatedly immersed in the rinsing for multiple rinsings to ensure the rinsing effect. For example, the utility model patent with application number CN202322774396.2 discloses a fabric rinsing machine, in which a first cleaning wool roller and a second cleaning wool roller arranged up and down are provided in the rinsing tank, and the first cleaning wool roller and the second cleaning wool roller are both immersed in the rinsing tank. The rinsing tank is provided with a plurality of guide rollers on both sides of the rinsing tank, and the discharge end of the rinsing tank is provided with an upper squeeze roller and a lower squeeze roller arranged up and down, and the rinsing tank is provided with a cleaning wool roller for cleaning the two sides of the textile fabric at the discharge end. The fabric rinsing machine disclosed in the patent cleans both sides of the textile fabric through the first cleaning wool roller and the second cleaning wool roller, and immerses the fabric in the rinsing liquid through the guide roller, thereby improving the rinsing effect of the fabric. However, the cleaning roller will brush off the thread ends and fluff on the surface of the fabric (especially linen, which has short linen fibers and produces some cotton-like floating hair during the weaving process) and make them adhere to the surface above the liquid level. After the fabric is pulled out of the rinsing liquid, it will also adhere to its surface, making it impossible to effectively clean it. In addition, the first cleaning roller and the second cleaning roller rotate under the traction of the fabric, so that there is basically no relative movement between the cleaning roller and the fabric, making the brushing effect on the fabric surface unsatisfactory. Therefore, in view of the shortcomings of the existing fabric rinsing machine in the rinsing process of linen, this application proposes a linen rinsing device that can effectively solve the above technical problems. Summary of the invention

[0004] The present invention aims to provide a rinsing device for linen cloth, so as to solve the problem that the existing wool cleaning roller cannot effectively clean the linen cloth, and that impurities such as thread ends and floating wool floating on the upper layer of the liquid surface cannot be quickly removed during the cleaning process, resulting in the linen cloth being attached to the surface of the rinsing liquid after being pulled out of the rinsing liquid, resulting in poor rinsing effect.

[0005] The present invention is achieved through the following technical solutions: A linen rinsing device, comprising a rinsing tank. Feed ports and discharge ports are respectively formed on the left and right side surfaces of the rinsing tank. A row of immersion rollers is rotatably arranged at the lower end of the rinsing tank. A row of turning rollers is rotatably arranged above the immersion rollers. A row of water decanting strip boxes is arranged between the horizontal heights of the immersion rollers and the turning rollers. A lifting assembly is commonly connected to the front ends of the water decanting strip boxes. A hose is connected to the rear ends of the water decanting strip boxes. A row of drain pipes connected to the corresponding hoses is arranged on the rear side surface of the rinsing tank; A brushing mechanism is arranged between the two immersion rollers at the leftmost end. The brushing mechanism includes a C-shaped pipe fixed on the rinsing tank. The upper and lower ends of the C-shaped pipe are respectively connected with first piston rods extending into the rinsing tank through first piston blocks. The ends of the two first piston rods are both connected with brush strips facing each other up and down. And bristles are arranged on the opposite surfaces of the two brush strips. A guide post is arranged on the upper outer side of the C-shaped pipe. A pressing rod vertically extending into the C-shaped pipe penetrates through the guide post. A second piston block is arranged at the lower end of the pressing rod. And hydraulic oil is filled in the C-shaped pipe between the second piston block and the two first piston blocks. A power mechanism for realizing the reciprocating up and down movement of the pressing rod is arranged at the top of the pressing rod extending out of the guide post.

[0006] As a further setting of the above solution, the power mechanism includes a driving motor. A pressing cam is arranged on the motor shaft of the driving motor. A roller acting on the pressing cam is arranged at the top end of the pressing rod. A spring is arranged between the roller and the guide post.

[0007] As a further setting of the above solution, guide rods are connected to the rear ends of the two brush strips. A guide cylinder acting on the guide rods is fixed on the rear side surface of the rinsing tank.

[0008] As a further setting of the above solution, the lifting assembly includes a lifting frame connected to the front end of the water decanting strip box. A telescopic driving member connected to the lifting frame is arranged at the upper end of the rinsing tank.

[0009] As a further setting of the above solution, the upper end of the water decanting strip box is open and arranged in the direction parallel to the immersion rollers. Each water decanting strip box is arranged between the gaps of the linen passing through the immersion rollers and the turning rollers for up and down turning.

[0010] As a further setting of the above solution, a liquid receiving tank is arranged on the rear side surface of the rinsing tank directly below the row of drain pipes. A filter hole plate is arranged on the liquid receiving tank. The lower end of the liquid receiving tank is connected with a liquid return storage tank. A liquid return pump is connected to the liquid return storage tank. The liquid outlet end of the liquid return pump is connected with a liquid return pipe communicating with the rinsing tank.

[0011] As a further setting of the above solution, a float switch is arranged inside the rinsing tank, and the float switch is arranged in the closed loop of the liquid return pump.

[0012] As a further setting of the above solution, each of the reversing rollers is arranged above the perpendicular bisector of the connection line of two adjacent dipping rollers.

[0013] As a further setting of the above solution, a feeding roller and a discharging roller are rotatably arranged in the rinsing tank at the feeding port and the discharging port, and a controller is arranged on the front side of the rinsing tank.

[0014] During the rinsing process of the linen fabric disclosed by the present invention, the linen fabric is subjected to the brushing action of the upper and lower brush strips perpendicular to the traction direction at the first time when it is immersed in the rinsing liquid. During the operation of the brushing mechanism, the driving mechanism drives the pressing rod to move up and down, so that the second piston block moves up and down in the C-shaped pipe. Then, under the action of the hydraulic oil, the first piston blocks at the upper and lower ends of the C-shaped pipe move synchronously and in opposite directions, so that the upper and lower brush strips move reciprocally and synchronously and in opposite directions perpendicular to the traction direction of the linen fabric. During the movement of the two brush strips, the oil stains and impurities on their surfaces are cleaned off by the bristles. And because the directions of the upper and lower bristles acting on the linen fabric are opposite, the problem of the traction deviation of the linen fabric caused by only a single force perpendicular to the traction direction can be offset, ensuring that the linen fabric moves in the middle during the traction process.

[0015] In addition, after the linen fabric is rinsed for a period of time, impurities such as thread ends and fluff cleaned from the linen fabric will float on the upper layer of the rinsing liquid and are separated into multiple areas by the linen fabric shuttling up and down. Therefore, the impurities on the upper layer of the liquid level in multiple areas cannot be cleaned simultaneously by discharging the upper layer of the rinsing liquid. At this time, the driving telescopic member can be periodically started to extend to press down the lifting frame. During the downward movement of the lifting frame, a row of water draining strip boxes will gradually extend into the rinsing liquid. When the upper end opening of the water draining strip box reaches the liquid level of the rinsing liquid, the upper layer liquid of the rinsing liquid will flow into the water draining strip box, and at the same time, the floating thread ends and fluff on the surface will also enter. Then, before the liquid inside the water draining strip box is full, the water draining strip box is lifted up until the height of the water draining strip box exceeds the drain pipe, and then through the communication action of the hose, the rinsing liquid and impurities in the water draining strip box are discharged from the rinsing tank together. Finally, through the filtering and intercepting action of the filter hole plate in the liquid receiving tank, the separation of the rinsing liquid and impurities can be realized, and the separated rinsing liquid can be sent back to the rinsing tank for recycling.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The linen rinsing device disclosed by the present invention is provided with a row of liftable water decanting strip boxes in the rinsing tank, and the water decanting strip boxes are connected to the drain pipe through hoses. When impurities such as lint and fluff float above the rinsing liquid, the top openings of the water decanting strip boxes are lowered to the same level as the liquid surface, and the floating impurities are brought in by the flowing liquid flowing into the water decanting strip boxes. Then, before the water decanting strip boxes are filled with liquid, they are lifted to a height exceeding the drain pipe, so that the hoses discharge a small amount of rinsing liquid and the impurities above the liquid surface from the rinsing tank. At the same time, since a row of water decanting strip boxes are arranged between the upper and lower folding gaps of the linen passing through the dipping roller and the folding roller, the impurities above the multiple water surface areas separated by the linen can be completely removed. Its structural design is novel and ingenious, effectively solving the problem that the impurities floating above the liquid surface during the linen rinsing process adhere to the fabric again, and improving the cleaning effect of the linen fabric.

[0017] On the basis of removing the impurities above the liquid surface through the water decanting strip boxes, the present invention further sets up a liquid receiving tank, and filters the discharged mixed liquid through a filter hole plate, realizing the separation of the rinsing liquid and the impurities. The separated rinsing liquid can be recycled back to the rinsing tank, reducing the waste of the rinsing liquid.

[0018] The linen rinsing device disclosed by the present invention adopts a specially designed brushing mechanism. The brushing mechanism reciprocates the upper and lower brush strips in the opposite direction and perpendicular to the traction direction of the linen to brush the surface of the linen, which can not only clean the oil and impurity on the surface of the linen, but also avoid the problem of linen traction deviation caused by a single force perpendicular to the traction direction. In addition, the design of the driving mechanism is novel. Using the hydraulic oil inside the C-shaped pipe as the transmission medium, only by driving the up and down movement of the pressing rod by the motor can the actions of the two brush strips be realized, and the contact between the liquid inside the rinsing tank and the driving mechanism is effectively isolated, having a good use effect.

Detailed implementation manners

[0021] In order to enable those skilled in the art to better understand the solution of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application.

[0022] It should be noted that, without conflict, the embodiments in this application and the features in the embodiments can be combined with each other. The following will refer to the attached Figures 1 to 7 drawings and describe this application in detail in combination with the embodiments. Embodiment 1

[0023] Embodiment 1 discloses a linen rinsing device. Referring to the attached Figures 1 - 4 drawings, it includes a rinsing tank 1 welded by stainless steel enclosure, and the upper end of the rinsing tank 1 is open, and the lower end is connected with a corresponding sewage pipe (not shown in the figure). Feeding ports 101 and discharging ports 102 are respectively opened at the upper ends of the left and right side surfaces of the rinsing tank 1, and then a feeding roller 3 and a discharging roller 4 are rotatably arranged inside the rinsing tank 1 corresponding to the feeding port 101 and the discharging port 102. In addition, a controller 2 for controlling the entire rinsing device is arranged on the front side surface of the rinsing tank 1.

[0024] A row of immersion rollers 5 is rotatably installed at the lower end of the inner cavity of the rinsing tank 1, and the intervals between each immersion roller 5 are equal. A row of turning rollers 6 is rotatably installed at the upper end of the inner cavity of the rinsing tank 1, and each turning roller 6 is arranged above the mid-perpendicular line connecting two adjacent immersion rollers 5, so that the linen enters the bottom of the rinsing tank 1 under the guidance of the feeding roller 3, extends out of the rinsing liquid level after passing through two immersion rollers 5, and then is guided by the turning roller 6 into the rinsing liquid, and is discharged from the rinsing tank 1 by the discharging roller 4 after multiple turnings (refer to the attached Figure 4 drawings).

[0025] Referring to the attached Figure 2 drawings, attached Figure 3 drawings and attached Figure 5, in the rinsing tank 1 between the horizontal heights of the dipping roller 5 and the turning-back roller 6, there is arranged a row of water decanting strip boxes 7. The water decanting strip boxes 7 are arranged parallel to the dipping roller 5, and their upper ends are open. Each water decanting strip box 7 is arranged between the gaps where the linen fabric turns back up and down. At the front ends of the row of water decanting strip boxes 7, a lifting frame 8 is fixedly connected together. Then, at the upper end of the rinsing tank 1, there is a driving telescopic member 9 for driving the lifting frame 8 to move up and down. In addition, to ensure the stable up and down movement of the lifting frame 8, a vertical sliding rail 10 is fixed on the front inner wall of the rinsing tank 1. Then, a sliding opening 801 interacting with the vertical sliding rail 10 is formed on the lifting frame 8. At the bottom of the rear ends of all the water decanting strip boxes 7, a hose 11 is connected. Then, on the rear side of the rinsing tank 1, a row of L-shaped drain pipes 12 is connected. One end of the drain pipe 12 extends out of the rinsing tank 1. Finally, the end of the hose 11 is connected to the drain pipe 12.

[0026] Reference appendix Figure 1 , appendix Figure 3 , appendix Figure 6 and appendix Figure 7 , between the two dipping rollers 5 at the leftmost end, a brushing mechanism 13 is arranged. The brushing mechanism 13 includes a C-shaped pipe 130 fixed on the front side of the rinsing tank 1. In the upper and lower ends of the C-shaped pipe 130, first piston blocks 132 are arranged. Then, first piston rods 133 extending into the rinsing tank 1 are connected to the two first piston blocks 132. Brush strips 134 are fixedly connected to the two first piston rods 133. A large number of bristles 135 are arranged on the opposite sides of the two brush strips 134. Guide rods 136 are connected to the rear ends of the two brush strips 134. Then, a guide cylinder 137 interacting with the guide rods 136 is fixed on the rear side of the rinsing tank 1.

[0027] On the outer upper end of the C-shaped pipe 130, a guide post 138 is arranged. A pressing rod 139 vertically extending into the inner cavity of the outer end of the C-shaped pipe 130 penetrates through the guide post 138. Then, a second piston block 131 adapted to the C-shaped pipe 130 is arranged at the lower end of the pressing rod 139. Hydraulic oil is filled in the C-shaped pipe 130 between the second piston block 131 and the two first piston blocks 132. At the top of the pressing rod 139 extending out of the guide post 138, a power mechanism 14 for driving the pressing rod 139 to reciprocate up and down is arranged. Specifically, the power mechanism 14 includes a bracket 141 fixed on the front side of the rinsing tank 1. A driving motor 142 is arranged on the bracket 141. A pressing cam 143 is arranged on the motor shaft of the driving motor 142. Then, a roller 144 interacting with the pressing cam 143 is arranged at the top of the pressing rod 139. Finally, a spring 145 is connected between the roller 144 and the top of the guide post 138.

[0028] During the process of rinsing the linen fabric, the linen fabric rinsing device disclosed in Embodiment 1 is completely immersed in the rinsing liquid when passing through the two leftmost immersion rollers 5, and the two brush bars 134 in the brushing mechanism 13 are respectively located on the upper and lower sides of the linen fabric.

[0029] During the traction movement of the linen fabric, the driving motor 142 is synchronously started to make the pressing cam 143 rotate. Then, the roller 144 reciprocates up and down under the action of the pressing cam 143 and the spring 145, thereby driving the pressing rod 139 and the second piston block 131 to reciprocate up and down. When the second piston block 131 moves up and down in the C-shaped tube 130, the two first piston blocks 132 will move in opposite directions back and forth through the action of hydraulic oil. Then, the upper and lower brush bars 134 will move back and forth perpendicular to the traction direction of the linen fabric, so that the bristles 135 brush the linen fabric. At the same time, since the directions of the upper and lower bristles acting on the linen fabric are opposite, the problem of linen fabric traction deviation caused by only a single force perpendicular to the traction direction can be offset.

[0030] After the linen fabric rinsing device has been running for a period of time, the lint and floating hairs that have fallen from the surface of the linen fabric will float on the upper layer of the rinsing liquid. At this time, the controller 2 can be used to control the driving telescopic member 9 to extend and press the lifting frame 8 downward. During the downward movement of the lifting frame 8, a row of water decanting strip boxes 7 will gradually extend into the rinsing liquid. When the upper opening of the water decanting strip box 7 reaches the liquid level of the rinsing liquid, the upper layer liquid of the rinsing liquid will flow into the water decanting strip box 7, and at the same time, the floating lint and fluff on the surface will also enter. Then, before the liquid inside the water decanting strip box 7 is full, the water decanting strip box 7 is lifted until the height of the water decanting strip box 7 exceeds the drain pipe 12. Finally, through the connection of the hose 11, the water and impurities in the water decanting strip box 7 are discharged from the rinsing tank 1 together. At the same time, since the multiple water decanting strip boxes 7 in Embodiment 1 are arranged between the gaps where the linen fabric folds back and forth, the rinsing liquid in each interval separated by the linen fabric can effectively remove the floating impurities on its upper layer. Embodiment 2

[0031] Embodiment 2 discloses a linen fabric rinsing device improved and designed based on Embodiment 1. The same parts as those in Embodiment 1 will not be described again. The differences are as shown in the attached Figure 2 and the attached Figure 4 .

[0032] In the second embodiment, a liquid receiving tank 15 is further arranged on the rear side of the rinsing tank 1 and located below a row of drain pipes 12. A filter plate 16 for filtering out lint and fluff in the rinsing liquid is installed in the liquid receiving tank 15. Then, a connecting pipe 17 is arranged at the bottom of the liquid receiving tank 15 below the filter plate 16, and a liquid return storage tank 18 is connected to the end of the connecting pipe 17. A liquid return pump 19 is connected to the lower end of the liquid return storage tank 18. Then, a liquid return pipe 20 is connected to the liquid outlet end of the liquid return pump 19, and the end of the liquid return pipe 20 is communicated with the rinsing tank 1. In addition, a float switch 21 is arranged inside the rinsing tank 1, and the float switch 21 is connected in the closed loop of the liquid return pump 19.

[0033] With the above design in the second embodiment, after the decanting strip box 7 discharges the rinsing liquid and impurities through the hose 11 and the drain pipe 12, the liquid receiving tank 15 receives them. After the filter plate 16 removes impurities such as lint and fluff, the liquid flows back into the liquid return storage tank 18. At this time, the liquid level in the rinsing tank 1 drops, and the float switch 21 closes to start the liquid return pump 19. Then, the rinsing liquid recovered in the liquid return storage tank 18 is re-introduced into the rinsing tank 1 through the liquid return pump 19, realizing the recycling of the upper-layer rinsing liquid and reducing the waste of the rinsing liquid.

[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
