Description

Technical Field

[0001] The utility model relates to the field of transfer printing equipment, and more specifically, to a conveyor belt structure of a roller transfer printing machine. Background Art

[0002] The roller transfer machine is a type of heat transfer printing machine, mainly used to transfer patterns and text onto various materials. The working principle of the roller transfer machine is to transfer the designed pattern or text onto the target material through heat transfer technology. Currently, the pattern on the transfer paper is generally transferred to the fabric through high temperature and pressure to complete the transfer part.

[0003] The roller transfer machine consists of a machine body and a conveyor belt. After the fabric completes the heat transfer step in the machine body, the fabric will be conveyed out through the conveyor belt located on one side of the machine body. However, when transferring thinner fabrics, especially knitted fabrics, the temperature of the fabric drops sharply when it just enters the conveyor belt, causing the fabric to shrink easily on the conveyor belt, making the fabric prone to wrinkling later.

[0004] Therefore, new solutions need to be proposed to solve this problem. Utility Model Content

[0005] In view of the deficiencies in the prior art, the present invention aims to provide a conveyor belt structure for a roller transfer machine.

[0006] The above technical purpose of the present utility model is achieved through the following technical solutions: a conveyor belt structure of a roller transfer machine, including a frame and several conveyor rollers, both ends of the conveyor rollers are fixed on the frame, and several of the conveyor rollers are covered with the same conveyor belt. Two mounting boxes are fixedly connected to the frame, and a mounting block is slidably connected in the mounting box. The mounting block slides along the height direction of the mounting box. An extrusion roller located above the conveyor belt is provided between the two mounting boxes, and the two ends of the extrusion roller are respectively rotatably connected to the two mounting blocks.

[0007] The utility model is further configured as follows: a through hole is opened on the top surface of the installation box, a driving rod with one end fixedly connected to the installation block is provided in the through hole, a compression spring is provided on the outer sleeve of the driving rod, and the two ends of the compression spring respectively contact the installation block and the upper inner wall of the installation box.

[0008] The utility model is further configured as follows: a through hole is provided on the driving rod, and a limiting rod passes through the through hole.

[0009] The utility model is further configured as follows: the number of the through holes is two, and one of the through holes is arranged close to the upper end of the driving rod.

[0010] The utility model is further configured as follows: a waist-shaped hole is opened on one side of the two installation boxes facing each other, one end of the squeezing roller passes through the waist-shaped hole and is connected to the installation block, and when one end of the squeezing roller contacts the upper end of the waist-shaped hole, the two through holes are just exposed outside the installation box.

[0011] The utility model is further configured as follows: the diameter of the through hole close to the upper end of the driving rod is equal to the diameter of the limiting rod, and the diameter of the other through hole is larger than the diameter of the limiting rod.

[0012] In summary, the present invention has the following beneficial effects:

[0013] When thinner knitted fabrics need to be transferred in the machine body, people slide the mounting block in the mounting box so that the squeezing roller presses the fabric tightly against the conveyor belt. The squeezing roller is close to the machine body so that the fabric can be squeezed by the squeezing roller just after it leaves the machine body. During the rapid cooling process, the fabric is restricted by the squeezing roller, which reduces the shrinkage of the fabric. The squeezing roller can move up and down, so that when people transfer thicker fabrics or woven fabrics, the fabric itself is not easily shrunk. At this time, people can move the squeezing roller upward so that the squeezing roller does not affect the transmission of the fabric. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0019] Roller transfer machine conveyor belt structure, such as Figure 1 and Figure 2As shown, it includes a frame 1 and several conveyor rollers 2, both ends of the conveyor rollers 2 are fixed on the frame 1, and the several conveyor rollers 2 are covered with the same conveyor belt 3. The movement of the conveyor belt 3 is driven by the rotation of the several conveyor rollers 2. The machine body is located on one side of the frame 1. After the cloth is thermally transferred in the machine body, it is conveyed out through the conveyor belt 3. Two mounting boxes 4 are fixedly connected to the frame 1. The mounting boxes 4 are slidably connected with mounting blocks 5. The mounting blocks 5 slide along the height direction of the mounting boxes 4. A squeezing roller 6 located above the conveyor belt 3 is provided between the two mounting boxes 4. The squeezing roller 6 is set on the side of the frame 1 close to the machine body. The two ends of the squeezing roller 6 are rotatably connected to the two mounting blocks 5. When thinner knitted fabrics need to be transferred in the machine body, people can The sliding mounting block 5 in the mounting box 4 allows the squeezing roller 6 to press the cloth against the conveyor belt 3. The squeezing roller 6 is close to the machine body, so that the cloth can be squeezed by the squeezing roller 6 just after it leaves the machine body. During the rapid cooling process of the cloth, the cloth is restricted by the squeezing roller 6, and the fit between the cloth and the conveyor belt 3 is made tighter, reducing the degree of shrinkage of the cloth. The squeezing roller 6 can move up and down, so that when people transfer thicker cloth or woven cloth, the cloth itself is not easy to shrink. At this time, people can move the squeezing roller 6 upward so that the squeezing roller 6 does not affect the transmission of the cloth. The squeezing roller 6 is moved and adjusted by the sliding mounting block 5. The mechanical structure itself will not be affected by the temperature, thereby ensuring the service life of the up and down adjustment structure of the squeezing roller 6.

[0020] like Figure 2 and Figure 3 As shown, a through hole 7 is provided on the top surface of the mounting box 4, and a driving rod 8 is provided in the through hole 7 at one end of which is fixedly connected to the mounting block 5. A compression spring 9 is provided on the outer sleeve of the driving rod 8, and the two ends of the compression spring 9 respectively contact the mounting block 5 and the inner wall of the mounting box 4. People control the up and down movement of the squeezing roller 6 by pulling the driving rod 8. The compression spring 9 always provides a downward force for the mounting block 5, so that the squeezing roller 6 can press the cloth onto the conveyor belt 3. A through hole 10 is provided on the driving rod 8, and a limit rod passes through the through hole 10. When people need to lift the squeezing roller 6 upward, they pull the driving rod 8 to move the squeezing roller 6 upward until the through hole on the driving rod 8 is released. The position 10 is exposed outside the installation box 4. At this time, people pass the limit rod through the through hole 10. The length of the limit rod is greater than the diameter of the through hole 7, so that the limit rod can limit the movement of the drive rod 8, so that the squeezing roller 6 is limited, so that there is a distance between the squeezing roller 6 and the conveyor belt 3, which does not affect the conveying process of the cloth. There are two perforations 10, one of which is set close to the upper end of the drive rod 8. The perforation 10 at the upper end of the drive rod 8 is always exposed outside the installation box 4, so that when the squeezing roller 6 presses the cloth onto the conveyor belt 3, people can insert the limit rod into the perforation 10 at the upper end of the drive rod 8, so that the limit rod has a position to be placed.

[0021] like Figure 2 and Figure 3 As shown, a waist-shaped hole 11 is provided on the side facing each other of the two mounting boxes 4, and one end of the squeezing roller 6 passes through the waist-shaped hole 11 and is connected to the mounting block 5. When one end of the squeezing roller 6 contacts the upper end of the waist-shaped hole 11, the two through-holes 10 are just exposed outside the mounting box 4. This arrangement ensures that when the limit rod limits the driving rod 8, the position of the squeezing roller 6 is the upper limit position, thereby ensuring that the distance between the squeezing roller 6 and the conveyor belt 3 is the maximum, minimizing the interference of the squeezing roller 6 on the conveyor belt. The diameter of the through-hole 10 near the upper end of the driving rod 8 is equal to the diameter of the limit rod, and the diameter of the other through-hole 10 is equal to the diameter of the limit rod. The diameter is larger than the diameter of the limit rod. When the limit rod is placed in the through hole 10 at the upper end of the driving rod 8, the contact area between the outer peripheral wall of the limit rod and the inner peripheral wall of the through hole 10 is large, so that the friction between the limit rod and the inner wall of the through hole 10 is large. During the shaking of the extrusion roller 6, the limit rod is not easy to fall out. When the limit rod passes through the through hole 10 near the lower end of the driving rod 8, the diameter of the through hole 10 is larger than the diameter of the limit rod, which facilitates the insertion of the limit rod into the through hole 10. After the limit rod is inserted into the through hole 10, under the action of the elastic force of the compression spring 9, the limit rod will be pressed against the inner wall of the through hole 10, which can also ensure that the limit rod will not fall out.
