A kind of grey cloth high efficiency bleaching equipment

Abstract

The invention discloses a grey cloth high-efficiency bleaching device, which belongs to the field of bleaching. The grey cloth high-efficiency bleaching device arranges two groups of rubbing rollers in a bleaching box. During bleaching, the two groups of rubbing rollers are controlled to approach and contact each other, so that the grey cloth is squeezed and clamped to present a wave shape. The rotation of the two groups of rubbing rollers can produce a rubbing effect on the grey cloth, thereby accelerating the penetration of the bleaching liquid into the grey cloth. At the same time, during rotation, the liquid changing strip continuously undergoes a process of being subjected to force deformation and restoring the deformation, so that the liquid changing strip continuously and repeatedly undergoes a process of being subjected to force to squeeze out the bleaching liquid and restoring the deformation to absorb the bleaching liquid. Therefore, during rubbing, the flow speed of the bleaching liquid around the grey cloth at that location is effectively accelerated, and the penetration of the bleaching liquid into the grey cloth is further accelerated. Compared with the prior art, the bleaching efficiency is significantly improved, and the bleaching uniformity is improved.

[0038] 1 side plate, 2 multi-convex rubbing rollers, 3 liquid exchange strips, 31 positioning ends, 32 flexible rubbing ends, 33 ventilation sheets, 4 liquid absorption layers, 5 control balloons, 6 bleaching boxes, 7 guide rollers, 8 electric cylinders, 201 liquid exchange holes, 202 electric push rods, and 203 liquid pushing circular plates. DETAILED DESCRIPTION

[0039] The following will combine 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 the embodiments. All other embodiments obtained by ordinary technicians in this field without creative work based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0040] The first implementation method:

[0041] See also Figure 1-Figure 2 , the hollow arrow in the figure indicates the moving direction of the grey cloth, a indicates the bleaching liquid, and b indicates the grey cloth. An efficient bleaching device for grey cloth comprises a bleaching box 6 with a control chip, and guide components are installed at both ends of the bleaching box 6. The guide components comprise two guide rollers 7 respectively installed at the upper end of the edge of the bleaching box 6 and installed at the bottom end of the bleaching box 6. Two groups of rubbing roller plates are arranged inside the bleaching box 6. The grey cloth passes through the two guide rollers, two groups of rubbing roller plates distributed up and down, and two guide rollers of another guide component, and both ends of the grey cloth are located outside the bleaching box 6;

[0042] See also Figure 4-Figure 5The rubbing roller plate includes two side plates 1 and a plurality of multi-protrusion rubbing rollers 2 connected between the two side plates 1 through an electric rotating shaft. The outer ends of the multi-protrusion rubbing rollers 2 are fixedly inlaid with a plurality of groups of evenly distributed liquid changing strips 3 in the radial direction. The lower ends of the two side plates 1 are installed in the bleaching box 6 through a lifting component. The electric rotating shaft and the lifting component are connected to the control chip signal in the bleaching box 6. During bleaching, the two groups of rubbing rollers are controlled by the lifting component to approach and separate from each other. The electric rotating shaft can control the rotation of the multi-protrusion rubbing rollers 2 during bleaching, which is convenient for the realization of the rubbing action.

[0043] The upper kneading roller plate is fixedly connected to the inner wall of the bleaching box 6; the lower kneading roller plate only contacts the inner wall of the bleaching box 6, and electric cylinders are installed between the lower ends of the two side plates of the lower kneading roller plate and the bottom of the bleaching box. The electric cylinder 8 can control the lower kneading roller plate to approach or move away from the upper kneading roller plate.

[0044] It should also be noted that when controlling the rotation of the multi-convex rubbing rollers 2, the rotation directions of the two groups of multi-convex rubbing rollers 2 are controlled to be the same, so that the forces exerted on the grey cloth by the two groups of multi-convex rubbing rollers 2 during rotation are opposite, which significantly improves the rubbing effect on the grey cloth, thereby effectively improving the penetration of the bleaching solution into the grey cloth and improving the bleaching efficiency.

[0045] The multiple multi-convex rubbing rollers 2 do not contact each other, and the distance between two adjacent multi-convex rubbing rollers 2 is not greater than the diameter of the multi-convex rubbing rollers 2. The multiple multi-convex rubbing rollers 2 above and the multiple multi-convex rubbing rollers 2 below are spaced apart from each other, so that after the upper and lower groups of rubbing roller plates are close to each other, it is effectively ensured that the two can conflict with each other, and the rubbing effect is effectively ensured. The two radially adjacent groups of liquid changing strips 3 are also spaced apart from each other, and the distance between two laterally adjacent liquid changing strips 3 is less than the length of the liquid changing strips 3, so that when rubbing, the contact between the multiple liquid changing strips 3 and the grey cloth is not easy to have four corners, thereby effectively ensuring the uniformity of bleaching.

[0046] See also Figure 6-Figure 7 The liquid exchange strip 3 includes a positioning end 31, a flexible rubbing end 32 fixedly connected to the outside of the positioning end 31, and a plurality of ventilation sheets 33 fixedly embedded on the positioning end 31. The inner wall of the positioning end 31 is fixedly connected with a control balloon 5. The space surrounded by the control balloon 5, the positioning end 31 and the inner wall of the flexible rubbing end 32 is filled with a liquid absorbing layer 4. The ventilation sheet 33 is a hard porous structure, and the ventilation sheet 33 is connected to the control balloon 5 and the inner cavity of the multi-protrusion rubbing roller 2. The inner cavity of the multi-protrusion rubbing roller 2 is saturated with an inert gas, such as Figure 8When rubbing, the liquid changing strip 3 is deformed by force at the place where the two multi-convex rubbing rollers 2 conflict with each other, so that the bleaching liquid adsorbed inside it seeps out and moves quickly toward the grey cloth, further accelerating the penetration of the bleaching liquid into the grey cloth. When it rotates to the part where the two do not conflict with each other, the liquid changing strip 3 recovers its deformation, adsorbs and stores the bleaching liquid. In addition, when the liquid changing strip 3 is subjected to force due to the conflict between the two, the control balloon 5 inside it is also deformed by force, so that the internal gas is transferred to the multi-convex rubbing rollers 2. When there is no force, the gas quickly returns to the control balloon 5, so that it recovers its deformation, thereby accelerating the recovery of the deformation of the liquid changing strip 3 and the adsorption of the bleaching liquid, thereby effectively ensuring that a certain amount of bleaching liquid is squeezed out of the liquid changing strip 3 each time it is rubbed;

[0047] The control balloon 5 is an elastic spherical structure, and the end of the control balloon 5 extends to the inner side of the flexible rubbing end 32, which effectively ensures that when the liquid changing strip 3 is subjected to force, the control balloon 5 can also be subjected to extrusion force, effectively ensuring the transfer of gas in the multi-protrusion rubbing roller 2 and the control balloon 5. The flexible rubbing end 32 is an elastic porous structure, and the positioning end 31 is a hard sealing structure, and the positioning end 31 is completely located in the multi-protrusion rubbing roller 2, so that its hard structure is not easy to contact with the grey cloth, thereby effectively avoiding the occurrence of hooking and wear of the grey cloth during bleaching.

[0048] S1. Please refer to Figure 2 First, the grey cloth is installed in the bleaching box 6, and the grey cloth is passed through two groups of rubbing rollers arranged up and down, and then the bleaching liquid is introduced into the bleaching box 6 until the bleaching liquid submerges the rubbing rollers located at the top;

[0049] The temperature of the bleaching liquid in the bleaching box 6 is 60-80° C., which effectively accelerates the movement speed of the bleaching liquid molecules toward the grey cloth and improves the bleaching efficiency.

[0050] The guide assembly includes two sets of guide rollers located inside and outside the bleaching box 6, respectively. The guide rollers effectively control the stability of the grey cloth in the bleaching box 6, so that it can be in a relatively straight state, which is convenient for it to be pulled outward;

[0051] S2. Please refer to Figure 3 , the grey cloth is controlled to move at a uniform speed in the bleaching box 6 through an external traction device, and at the same time, a group of rubbing rollers below are controlled to move upward until the two rubbing rollers contact each other across the grey cloth, so that the grey cloth presents a wave shape between the two groups of rubbing rollers;

[0052] S3, controlling the rotation of the multi-convex rollers 2 on the two groups of rubbing roller plates, so that the two upper and lower adjacent multi-convex rollers 2 have a rubbing effect on the grey cloth, accelerating the penetration of the bleaching solution into the grey cloth, and at the same time, during the rotation, the liquid changing strips 3 on the multi-convex rollers 2 continuously undergo a process of deformation under force and recovery of deformation, during which the liquid changing strips 3 repeatedly undergo a process of squeezing out the bleaching solution under force and recovering the deformation to absorb the bleaching solution, further accelerating the penetration of the bleaching solution;

[0053] S4, washing the grey cloth moved outward through the guide assembly for multiple times to complete bleaching.

[0054] The second implementation method:

[0055] Based on the first embodiment, this embodiment changes the specific setting of the multi-protrusion roller 2, and the multi-protrusion roller 2 is not filled with inert gas, and 3 is an integrated structure made of highly adsorbent material, and the rest of the parts are consistent with the first embodiment.

[0056] like Fig. 9 The multi-convex roller 2 is a hollow structure, and a plurality of liquid exchange holes 201 distributed in a circular array are opened in the middle of the multi-convex roller 2. A one-way valve is installed at the liquid exchange hole 201 toward the mouth of the multi-convex roller 2. Fig.10 Two liquid pushing units are installed inside the multi-protrusion roller 2. The liquid pushing units include a liquid pushing circular plate 203 installed on the circular inner wall of the multi-protrusion roller 2 and an electric push rod 202 fixedly connected to the extended end of the liquid pushing circular plate 203. The electric push rod 202 matches the inner wall of the multi-protrusion roller 2.

[0057] In this embodiment, when the two rubbing rollers collide with each other across the grey cloth, on the one hand, the multi-protrusion rubbing roller 2 rotates continuously to generate a rubbing force with the grey cloth, and at the same time, the liquid pushing unit continuously expands and contracts, so that the bleaching liquid is continuously absorbed into the multi-protrusion rubbing roller 2 and continuously squeezed out from 3 places and directly acts on the grey cloth, so that the bleaching liquid can form a circulating flow, thereby accelerating the penetration of the bleaching liquid on the grey cloth and improving the bleaching efficiency.

[0058] Compared with the first embodiment, the bleaching liquid in this embodiment has a stronger impact on the grey cloth and better penetration. During the specific implementation, a suitable embodiment can be selected according to actual needs.

[0059] The above is only a preferred specific implementation manner of the present invention; but the protection scope of the present invention is not limited thereto; any technician familiar with the technical field within the technical scope disclosed by the present invention; any equivalent replacement or change based on the technical solution and improved concept of the present invention shall be covered by the protection scope of the present invention.
