Description

Technical Field

[0001] The utility model relates to the field of fabric heat transfer processing, and more specifically, to a roller transfer machine. Background Art

[0002] The working principle of the roller transfer machine is mainly to transfer ink or dye to the surface of the material to be printed through a rotating roller, thereby realizing the pattern transfer process. This rotating roller is usually called a transfer roller.

[0003] After the transfer roller transfers the pattern on the transfer paper to the fabric, the transferred part of the fabric is conveyed out through the conveyor belt on one side of the transfer machine. During the transfer process, the motor that drives the transfer roller to rotate is generally driven synchronously with the motor that drives the conveyor belt, so that the transfer speed of the transfer roller is the same as the conveyor belt speed, so that as much fabric as the transfer is completed can be smoothly conveyed out. The effective width of the existing fabric is generally called the width, and the effective length of the fabric is called the piece length. Before the fabric is transferred, we need to cut the fabric so that the effective length of the fabric meets our needs. However, during the cutting process, the length of the fabric cut may deviate from the expected length. Therefore, it is necessary to design a roller transfer machine that can adjust the effective length of the fabric during the transfer process. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention aims to provide a roller transfer machine.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a roller transfer machine, comprising a machine body, a transfer roller is provided on the machine body, a conveyor belt is provided on one side of the machine body, a squeezing roller is provided above the conveyor belt, the squeezing roller is used to press the fabric onto the conveyor belt, and the motor driving the transfer roller to rotate is independent of the motor driving the conveyor belt to rotate.

[0006] The utility model is further configured such that the pressure exerted by the squeezing roller on the fabric increases as the speed of the conveyor belt increases.

[0007] The utility model is further configured as follows: a frame is provided on one side of the machine body, the conveyor belt is provided on the frame, two cylinders are fixedly connected to the frame, the cylinders include a cylinder body and an output shaft, and the output shafts of the two cylinders are respectively fixedly connected to the two ends of the extrusion roller.

[0008] The utility model is further configured as follows: the conveyor belt comprises a belt and a plurality of transmission rollers, the belt is wrapped around all the transmission rollers, and one of the transmission rollers is located below the squeezing roller.

[0009] The utility model is further configured as follows: the squeezing roller is arranged at one end of the frame close to the machine body.

[0010] The utility model is further configured as follows: the upper side of the frame is a workbench for placing fabrics and transfer paper, and the two cylinders are both arranged close to the upper end of the frame.

[0011] In summary, the present invention has the following beneficial effects:

[0012] The squeezing roller is used to press the fabric against the conveyor belt so that the fabric and the conveyor belt are not easily moved relative to each other, ensuring that the fabric conveying speed is consistent with the conveyor belt conveying speed. The motor that drives the transfer roller and the motor that drives the conveyor belt are independent of each other, so that people can independently control the conveyor belt conveying speed. By slightly increasing or decreasing the conveyor belt conveying speed, the effective length of the fabric can be fine-tuned during the transfer process, so that the effective length of the fabric is closer to people's expectations.

[0016] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0017] A roller transfer machine, such as Figure 1 and Figure 2As shown, it includes a body 1, a transfer roller is provided on the body 1, a conveyor belt is provided on one side of the body 1, and a squeezing roller 2 is provided above the conveyor belt, the squeezing roller 2 is used to press the fabric on the conveyor belt, and the squeezing roller 2 is used to press the fabric against the conveyor belt, so that the fabric and the conveyor belt are not easily moved relative to each other, ensuring that the fabric conveying speed is consistent with the conveying speed of the conveyor belt, the motor driving the transfer roller to rotate and the motor driving the conveyor belt to rotate are independent of each other, so that people can independently control the conveying speed of the conveyor belt. After people cut, when the effective length of the fabric is less than the actual required length, people adjust the speed of the conveyor belt so that the speed of the conveyor belt is slightly faster than the speed of the transfer roller. When the speed of the conveyor belt is slightly faster than the speed of the transfer roller, the fabric will continue to be fed by the conveyor belt at a higher speed after passing through the transfer roller. Continue to pull the fabric, so that the part of the fabric between the transfer roller and the conveyor belt is stretched, thereby increasing the length of the fabric, and then making the length of the fabric close to the length we actually need. After people cut, when the effective length of the fabric is greater than the actual required length, people adjust the speed of the conveyor belt so that the speed of the conveyor belt is slightly slower than the speed of the transfer roller. When the speed of the conveyor belt is slightly lower than the speed of the transfer roller, the transfer roller will provide greater traction to push the fabric forward, while the conveyor belt will lag behind relatively. This mismatched speed difference will cause the fabric to be slightly tightened under the traction of the transfer roller, causing the fabric to shrink slightly, thereby reducing the length of the fabric. By fine-tuning the speed of the conveyor belt, the effective length of the fabric can be adjusted during the transfer process, so that the length of the fabric is closer to our needs.

[0018] like Figure 1 and Figure 2 As shown, the pressure of the squeezing roller 2 on the fabric increases with the increase in the speed of the conveyor belt. When the conveyor belt speed increases, the friction required between the fabric and the conveyor belt needs to increase to ensure that the fabric and the conveyor belt are unlikely to move relative to each other. In this way, the pressure of the squeezing roller 2 on the fabric only needs to be at the critical point where the fabric and the conveyor belt do not move relative to each other, so that the pressure of the squeezing roller 2 on the fabric is not too great. A frame 3 is provided on one side of the machine body 1, and the conveyor belt is provided on the frame 3. Two cylinders are fixedly connected to the frame 3. The cylinders include a cylinder body 4 and an output shaft 5. The output shafts 5 of the two cylinders are respectively fixedly connected to the two ends of the squeezing roller 2. By providing two synchronously moving cylinders, the upward and downward movement of the squeezing roller 2 can be controlled, and the pressure of the squeezing roller 2 on the fabric can also be controlled. The conveyor belt includes a belt 6 and several drive rollers 7. The belt 6 is wrapped around all the drive rollers 7, and one of the drive rollers 7 is located below the squeezing roller 2. This arrangement ensures that when the fabric is squeezed by the squeezing roller 2, there is sufficient support force under the fabric, preventing excessive deformation of the belt 6 and ensuring smooth transmission of the conveyor belt.

[0019] like Figure 1 and Figure 2 As shown, the squeezing roller 2 is arranged at one end of the frame 3 close to the body 1, and the squeezing roller 2 is arranged close to the body 1, so that the position where the fabric is stretched or contracted is concentrated in the body 1. Since the temperature in the body 1 is relatively high, the area with relatively high temperature is more likely to cause the length of the fabric to change, thereby ensuring the effect of adjusting the length of the fabric. The upper side of the frame 3 is a workbench for placing the fabric and transfer paper, and the two cylinders 4 are both arranged close to the upper end of the frame 3. People place the fabric and transfer paper that are bonded to each other on the workbench. Under the action of the traction force of the transfer roller, the fabric and the transfer paper will enter the body 1 for transfer together. Since the temperature of the fabric just coming out of the body 1 is relatively high, the distance between the cylinder 4 and the fabric is increased, thereby reducing the influence of the heat on the fabric on the heat dissipation of the cylinder 4.
