Description

Technical Field

[0001] The utility model belongs to the technical field of machinery and relates to a pre-treatment device for jacquard fabrics. Background Art

[0002] Fabric pretreatment is a crucial step in textile production, which takes place before the fabric is cut and the final product is made.

[0003] The purpose of pretreatment is to improve or give specific properties to fabrics, ensure the quality of the finished product, extend its service life, and optimize subsequent processing steps. Fabric pretreatment involves a variety of different steps and methods, and heating and tensioning is one of the treatment methods. Heating and tensioning it can effectively eliminate the wrinkle structure on the fabric and effectively improve the surface smoothness of the fabric.

[0004] However, in the existing pretreatment operation, the fabric directly passes through a feed roller with a set temperature. Since the fabric passes through the roller at a high speed and in a short time, the pretreatment effect is relatively poor. Summary of the invention

[0005] The purpose of the utility model is to provide a pretreatment device for jacquard fabrics with high stability and compact structure in view of the above problems existing in the prior art.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A pretreatment device for jacquard fabrics, comprising a frame, characterized in that it also comprises an upper feed roller, a lower feed roller, a tension roller and a transmission assembly, wherein the upper feed roller is axially fixedly connected to the upper part of the frame, the lower feed roller is axially fixedly connected to the middle part of the frame, the tension roller is axially fixedly connected to the frame and the tension roller is located at the side of the lower feed roller, the transmission assembly connects the upper feed roller, the lower feed roller and the tension roller and can drive the upper feed roller, the lower feed roller and the tension roller to rotate synchronously through the transmission assembly.

[0008] The pretreatment device for jacquard fabrics creatively arranges an upper feed roller, a lower feed roller and a tensioning roller, and the jacquard fabrics to be pretreated are wound around the upper feed roller, the lower feed roller and the tensioning roller in sequence, thereby effectively increasing the contact area between the jacquard fabrics and the upper feed roller and the lower feed roller.

[0009] Since the upper feed roller and the lower feed roller are heated to the set temperature, the jacquard fabric is tensioned in a relatively high environment, thereby effectively improving the surface smoothness of the jacquard fabric.

[0010] The transmission assembly can make the upper feeding roller, the lower feeding roller and the tensioning roller rotate synchronously and continuously, which plays an appropriate traction role on the jacquard rice fabric and ensures that the jacquard fabric can pass through the pretreatment device smoothly.

[0011] In the above-mentioned pretreatment device for jacquard fabrics, the transmission assembly includes sprocket one, sprocket two, sprocket three, sprocket four, a transmission chain and a driving member, the driving member is fixedly connected to the bottom of the frame, the sprocket one is fixedly connected to the end of the upper feeding roller, the sprocket two is fixedly connected to the end of the lower feeding roller, the sprocket three is fixedly connected to the end of the tensioning roller, the sprocket four is connected to the driving member, and the transmission chain is meshed with sprocket one, sprocket two, sprocket three and sprocket four in sequence.

[0012] When the driving member drives the transmission chain to move continuously through sprocket four, since sprocket one, sprocket two and sprocket three are all engaged with the transmission chain, the upper feeding roller, the lower feeding roller and the tensioning roller can finally rotate stably and continuously.

[0013] In the above-mentioned pretreatment device for jacquard fabrics, the right sides of the sprocket 1, the sprocket 2 and the sprocket 4 are flush.

[0014] Such a structure can ensure that the transmission chain is stably engaged with the sprocket, sprocket two and sprocket four.

[0015] In the above-mentioned pre-treatment device for jacquard fabrics, the driving member is a motor, and the rotating shaft of the motor is fixedly connected to the sprocket four.

[0016] As the shaft of the motor continues to rotate, the sprocket wheel four can rotate steadily.

[0017] In the above-mentioned pretreatment device for jacquard fabrics, the interior of the upper feed roller is a cavity and a fluid heating medium is provided inside the upper feed roller.

[0018] In the above-mentioned pretreatment device for jacquard fabrics, the interior of the lower feed roller is a cavity and a fluid heating medium is provided inside the lower feed roller.

[0019] The fluid heating medium is usually oil with a relatively high temperature.

[0020] In the above-mentioned pretreatment device for jacquard fabrics, the tensioning roller includes a cylindrical shaft and a cylindrical contact cylinder. The number of the contact cylinders is several, and the several contact cylinders are all sleeved on the shaft and arranged in sequence along the length direction of the shaft.

[0021] In the above-mentioned pretreatment device for jacquard fabrics, the contact cylinder includes a fixed cylinder and a movable cylinder. There are two fixed cylinders, which are respectively fixedly connected to both ends of the shaft body, and the movable cylinder is limited between the two fixed cylinders.

[0022] In the above-mentioned pre-treatment device for jacquard fabrics, the number of the movable cylinders is several and the movable cylinders are made of flexible materials.

[0023] The flexible movable cylinder can avoid rigid contact between the movable cylinder and the jacquard fabric while ensuring appropriate friction between the movable cylinder and the jacquard fabric, thereby effectively improving the processing stability.

[0024] Of course, during the operation, the jacquard fabric only contacts the movable cylinder.

[0025] In the above-mentioned pre-treatment device for jacquard fabrics, the movable cylinder is made of rubber material.

[0026] Compared with the prior art, the pretreatment device for jacquard fabrics can cover the upper feed roller and the lower feed roller with a large area of ​​the jacquard fabric, and the jacquard fabric can be stably tensioned under the action of the tensioning roller. Therefore, after the jacquard fabric passes through the upper feed roller and the lower feed roller with set temperature, the jacquard fabric can be stably pretreated to ensure that the surface of the jacquard fabric is smooth.

[0027] At the same time, the driving member drives the upper feeding roller, the lower feeding roller and the tensioning roller to rotate, which effectively simplifies the structure of the entire device. The structure is relatively compact and has high practical value. BRIEF DESCRIPTION OF THE DRAWINGS
