[0041] like Figure 1-3 A cloth pre-treatment combined machine comprises, in order along the conveying direction of the first cloth: a front cloth loading mechanism 1, a desizing mechanism 2, a scouring mechanism 3, a first drying mechanism 4, a transfer cloth loading and unloading mechanism 5, a bleaching mechanism 6 and a second cloth unloading mechanism 7;

[0042] The first drying mechanism 4 includes: a first drying rack 41, a first drying roller 42 and a first cooling roller 43;

[0043] The first drying roller 42 and the first cooling roller 43 are rotatably mounted on the first drying rack 41. A plurality of the first drying rollers 42 and the first cooling rollers 43 are sequentially arranged along the conveying direction of the first cloth. The interior of the first drying roller 42 is filled with a heating medium; the interior of the first cooling roller 43 is filled with a cooling medium.

[0044] The transfer cloth loading and unloading mechanism 5 comprises: a first cloth lowering frame 51, a first cloth lowering device 52 and a first cloth lowering roller 53;

[0045] The first cloth lowering device 52 is mounted on the first cloth lower frame 51; a plurality of first cloth lowering rollers 53 are rotatably mounted on the first cloth lower frame 51 and are arranged in sequence from the first cooling roller 43 to the bleaching mechanism 6;

[0046] Part of the first cloth 101 passes through part of the first cooling roller 43 and then extends to the first cloth lowering device 52 ; part of the first cloth is output to the bleaching mechanism 6 along the first cloth lowering roller 53 .

[0047] This solution provides a combined machine for cloth pre-treatment, which is provided with a scouring mechanism 3, a first drying mechanism 4, a transfer cloth loading and unloading mechanism 5 and a bleaching mechanism 6 arranged in sequence. Temporary unloading or continued processing can be selected between the scouring treatment and the bleaching treatment, solving the problem that cloth pre-treatment requires continuous treatment and cannot be carried out step by step.

[0048] Specifically, the first cloth generally needs to be pre-treated, for example, including: desizing treatment, scouring treatment and bleaching treatment, and some will also be mercerized after bleaching; in this regard, the desizing mechanism 2 of this scheme is mainly used to desizing the first cloth, and can be replaced by a well-known mechanism with a desizing function, mainly to remove the sizing that must be added during the weaving of the original first cloth; the scouring mechanism 3 is mainly used to scour the first cloth, and can be replaced by a well-known mechanism with a scouring function, mainly to remove natural impurities in the first cloth, and to make the first cloth have a certain permeability; the bleaching mechanism 6 is mainly used to bleach the first cloth, and can be replaced by a well-known mechanism with a bleaching function, mainly to give the first cloth necessary and stable whiteness to ensure sufficient brightness during subsequent dyeing. The first drying mechanism 4 of the present invention is arranged at the rear end of the scouring mechanism 3 and at the front end of the intermediate cloth loading and unloading mechanism 5; because the first cloth has a certain amount of moisture on its surface after scouring, the first cloth will be input into the first drying mechanism 4 after being output from the scouring mechanism 3; the first drying roller 42 and the first cooling roller 43 of the first drying mechanism 4 are distributed in sequence, that is, the first drying roller 42 contacts the first cloth first, and the hollow structure inside the first drying roller 42 is filled with a heating medium, and the heating medium is in a relatively high temperature state, for example, hot oil or steam. After the heating medium indirectly contacts the first cloth through the first drying roller 42, the water molecules on the surface of the first cloth will evaporate faster, thereby achieving a drying effect; and the first cooling roller 43 contacts the first cloth last, and the hollow structure of the first cooling roller 43 is filled with a cooling medium, such as room temperature water, etc.; therefore, after the first cloth passes through the first drying mechanism 4 , having been cooled by the first cooling roller 43, the first cloth can be at a cooled temperature when it is delivered to the intermediate loading and unloading mechanism 5, avoiding localized high temperatures during storage and preventing burns to the cloth loaders. Therefore, the first cloth to be unloaded from the intermediate loading and unloading mechanism 5 can be unloaded at a cooled temperature, passing through the first unloading roller 53 and then being delivered to the combined machine by the first unloading device 52. For the first cloth to be bleached, the bleached first cloth can be passed through multiple first unloading rollers 53 before being delivered to the input of the bleaching mechanism 6. Since the first cloth to be bleached has been cooled, the bleaching temperature is primarily determined by the processing temperature within the bleaching mechanism 6, rather than the drying temperature of the first drying mechanism 4. Therefore, the drying temperature and the bleaching temperature do not conflict, ensuring that the bleaching solution is at the optimal processing temperature when it contacts the first cloth. This solution allows for the option of temporary unloading or seamless processing between the scouring and bleaching processes, resolving the problem of requiring continuous pre-treatment of the first cloth and preventing it from being performed step by step.

[0049] It can be optimized to further include: an intermediate cloth loading mechanism 8;

[0050] The intermediate cloth loading mechanism 8 comprises an intermediate cloth placing device 81 and an intermediate cloth loading roller 82;

[0051] The intermediate cloth placing device 81 is used to store the second cloth; the plurality of intermediate upper rollers 82 are rotatably mounted on the first lower cloth rack 51; the second cloth passes through the intermediate upper rollers 82 and the last part of the first lower cloth rollers 53, and then extends to the bleaching mechanism 6 and the second lower cloth mechanism 7.

[0052] This solution allows loading of materials through the intermediate cloth loading mechanism 8 after the intermediate cloth loading mechanism 8 has been used to unload materials. The intermediate cloth loading mechanism 8 is provided with an intermediate cloth placing device 81 for storing the second cloth. The second cloth only needs to pass through the intermediate upper roller 82 and the first cloth unloading roller 53 at the rear position before entering the bleaching mechanism 6 and the second cloth unloading mechanism 7. Therefore, a new second cloth can be input from the front of the bleaching mechanism 6 during processing, thereby improving the flexibility of cloth processing.

[0053] Optimally, the intermediate cloth loading mechanism 8 further comprises: a cloth loading fixing seat 83, a cloth loading swing seat 84 and a cloth loading swing roller 85;

[0054] The upper cloth fixing seat 83 is installed on the first lower cloth frame 51; a pair of upper cloth swinging rollers 85 are installed at intervals on the upper cloth swinging seat 84, and the upper cloth swinging seat 84 is installed on the upper cloth fixing seat 83 in a resettable and swingable manner; the second cloth passes through the middle upper wheel roller 82, the upper cloth swinging roller 85 and the first lower cloth roller 53 in sequence.

[0055] In this solution, the upper cloth fixing seat 83, the upper cloth swinging seat 84 and the upper cloth swinging roller 85 form a tension adjustment unit for the middle upper cloth; when the second cloth needs to be loaded, the second cloth can be wound around the middle upper roller 82 and the upper cloth swinging roller 85, and then the starting end of the second cloth can be docked with the end of the first cloth, and the end of the first cloth can be wound around the first lower cloth roller 53 arranged at the last position; in this way, the first cloth drives the second cloth to be conveyed to the bleaching mechanism 6 and the second cloth lowering mechanism 7; and since the second cloth is newly connected to the combined machine, the first cloth When the second cloth is loaded, there may be a tension difference between the transition area between the middle upper roller 82 and the first lower cloth roller 53. In this solution, a swingable upper cloth swing seat 84 is set between the middle upper roller 82 and the first lower cloth roller 53; when the second cloth passes through the two upper cloth swing rollers 85, the second cloth can drive the upper cloth swing rollers 85 to move, thereby indirectly adjusting the upper cloth swing seat 84 to swing through the upper cloth swing rollers 85 to balance the tension difference between the middle upper roller 82 and the first lower cloth roller 53, thereby improving the loading stability of the second cloth.

[0056] Optimally, the first lower cloth rack 51 is provided with a first lower cloth transverse rod 511, a first lower cloth vertical rod 512 and a second lower cloth vertical rod 513;

[0057] The first lower cloth transverse rod 511 extends laterally, one horizontal end of the first lower cloth transverse rod 511 is connected to the first lower cloth vertical rod 512, and the other horizontal end of the first lower cloth transverse rod 511 is connected to the second lower cloth vertical rod 513; some of the first lower cloth rollers 53 are distributed along the length direction of the first lower cloth transverse rod 511; some of the first lower cloth rollers 53 are respectively installed on the first lower cloth vertical rod 512 and the second lower cloth vertical rod 513.

[0058] The first lower cloth transverse rod 511 extends from the first lower cloth transverse rod 511 at one end to the second lower cloth vertical rod 513 at the other end; and the first lower cloth transverse rod 511 is provided with a first lower cloth roller 53 arranged along the first cloth conveying direction. The lateral distribution of the first lower cloth roller 53 can effectively stretch the first cloth, so that the first cloth can be fully cooled before entering the bleaching mechanism 6, thereby extending the cooling span of the first cloth; at the same time, the lateral extension of the first lower cloth transverse rod 511 can also effectively leave more space to accommodate the intermediate cloth placer 81 and the first lower cloth device 52 at the same time.

[0059] Optimally, the first drying rollers 42 are distributed obliquely in pairs, and multiple pairs of the first drying rollers 42 are arranged vertically; the first cooling rollers 43 are distributed obliquely in pairs, and at least one pair of the first cooling rollers 43 is arranged vertically at the end of multiple pairs of the first drying rollers 42.

[0060] In this embodiment, the first drying rollers 42 are arranged in pairs, with adjacent first drying rollers 42 positioned diagonally to facilitate the wrapping of the first cloth. This allows for faster transfer of the first cloth from one first drying roller 42 to the other, thereby improving drying efficiency. Furthermore, the vertical arrangement of multiple pairs of first drying rollers 42 and first cooling rollers 43 creates a more organized drying area, minimizing space and maximizing drying efficiency.

[0061] Optimally, multiple pairs of the first drying rollers 42 are arranged vertically to form a drying unit 410; multiple drying units 410 are arranged in sequence from the scouring mechanism 3 to the transfer upper and lower cloth mechanism 5; at least one pair of the first cooling rollers 43 is arranged vertically below the last position of the drying unit 410.

[0062] The first drying roller 42 of the present scheme may not be limited to a single vertical arrangement structure, but may also be arranged horizontally; specifically, the first drying roller 42 is arranged vertically to form a drying unit 410; and the drying unit 410 is arranged horizontally, and is arranged from the scouring mechanism 3 to the transfer upper and lower cloth mechanism 5; in this way, several pairs of first drying rollers 42 may be provided; and it is only necessary to arrange the first cooling roller 43 at the end of the drying unit 410 in the horizontal position, thereby making full use of the horizontal space and the vertical space to improve the heat dissipation efficiency, and the first cooling roller 43 may be used to cool the first cloth for temporary unloading.

[0063] Optimally, the second cloth dropping mechanism 7 includes: a cloth dropping device 71 and a cloth rolling device 72;

[0064] The swing arm roller of the open-width cloth dropping device 71 is used to drive the cloth to move to the cloth rolling device 72, and the cloth rolling device 72 is used to roll up the cloth.

[0065] The open-width cloth dropping device 71 is a well-known textile unloading mechanism, which is used to continuously drop the cloth (the first cloth or the second cloth) in an open width through its swinging swing arm roller; and the cloth will fall directly to the cloth winding device 72, and the cloth winding device 72 only needs to rotate continuously to automatically wind up the cloth.

[0066] It can be optimized to further include: a mercerizing mechanism 9 and a second drying mechanism 10;

[0067] The front cloth loading mechanism 1, the desizing mechanism 2, the scouring mechanism 3, the first drying mechanism 4, the intermediate cloth loading and unloading mechanism 5, the bleaching mechanism 6, the mercerizing mechanism 9, the second drying mechanism 10 and the second cloth unloading mechanism 7 are arranged in sequence;

[0068] The structure of the second drying mechanism 10 is the same as that of the first drying mechanism 4 .

[0069] The structure of the second drying mechanism 10 is similar to that of the first drying mechanism 4. After bleaching, the cloth enters the mercerizing mechanism 9 for mercerization. The roller structure within the mercerizing mechanism 9 maintains a certain tension on the cloth. The cloth is then treated with concentrated caustic soda and washed to remove alkali, thereby improving the surface finish, gloss, feel, and product quality. The second drying mechanism 10 is located between the mercerizing mechanism 9 and the second cloth unloading mechanism 7. It primarily dries the first or second cloth after mercerization. Cooling can be performed before unloading by the second cloth unloading mechanism 7 to prevent excessive processing temperatures from affecting unloading.

[0070] A cloth processing line is provided with the above-mentioned cloth pre-treatment combined machine.

[0071] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
