Description

Technical Field

[0001] This utility model relates to the field of heat transfer equipment technology, and in particular to an automatic fabric feeding device for heat transfer of fabric. Background Technology

[0002] Heat transfer printing involves printing a design onto heat transfer paper and then using high-temperature heat pressing to fix it onto clothing. During this process, the heat transfer paper automatically releases a curing agent, allowing the design to adhere firmly to the garment. In existing heat transfer equipment, the fabric and transfer film are simultaneously unwound and fed into the heat pressing mechanism, ensuring they are flush against each other. Currently, heat transfer equipment uses pressure rollers to press the fabric firmly on both sides, applying uniform pressure to ensure a smooth transport and prevent wrinkles or slippage. However, these cylindrical pressure rollers are only suitable for flat, thick, and low-elasticity fabrics. When transporting elastic or thin fabrics (such as knitted or stretch fabrics), wrinkles and curling edges easily occur on the sides, resulting in poor adhesion between the transfer film and the fabric. This leads to air bubbles, white edges, or blurred designs on the fabric edges after transfer. Therefore, those skilled in the art need to address these problems by making improvements to the existing technology. Utility Model Content

[0003] To address the aforementioned problems, this utility model discloses an automatic fabric feeding device for fabric heat transfer printing, which solves the problem in the prior art where the fabric feeding device cannot effectively position different types of fabric during the fabric conveying process, thus ultimately affecting the printing quality.

[0004] The specific technical solution is as follows: An automatic fabric feeding device for heat transfer printing includes a conveyor table disposed at one end of a heat transfer machine. The conveyor table includes a frame and a feeding table horizontally disposed at the upper end of the frame. Positioning pressure roller assemblies for flattening the fabric and both sides of the transfer film are symmetrically disposed on the top of both sides of the frame. The positioning pressure roller assembly includes a hinge seat, a support plate, a movable plate, and a pressure roller. The hinge seat is disposed on the top of one side of the frame. One side of the support plate is hinged to the hinge seat via a telescopic rod. The other side of the support plate has a notch for accommodating the movable plate. The pressure roller is rotatably disposed on the side of the movable plate near the support plate. The pressure roller includes a conical part and a cylindrical part distributed on the left and right sides, wherein the conical part is located at the end near the support plate. Both ends of the support plate are provided with fixed blocks, and both ends of the movable plate are provided with positioning blocks corresponding to the positions of the fixed blocks. A pin is horizontally provided on one side of the fixed block, and one end of the pin is horizontally embedded in the pin hole on the positioning block and rotatably connected thereto. A threaded rod is horizontally threaded through the other side of the fixed block, and each positioning block is provided with two insertion holes for accommodating the threaded rod. By rotating the threaded rod, one end of the threaded rod is embedded in the insertion hole, thereby positioning the support plate on the movable plate. When the threaded rod is embedded in one of the insertion holes, the cylindrical part of the pressure roller is in contact with the surface of the fabric feeding table. When the movable plate is lifted along the pin and the threaded rod is embedded in the other insertion hole, the conical part of the pressure roller is in contact with the surface of the fabric feeding table.

[0005] Furthermore, the support plate and the movable plate are respectively provided with a number of grooves on the side adjacent to each other to accommodate the two ends of the pressure roller.

[0006] Furthermore, the pressure roller shaft end is rotatably mounted on the upper surface of the movable plate via a rotating seat, and the pressure roller shaft end is parallel to the surface of the movable plate.

[0007] Furthermore, the distances between the two insertion holes and pin holes are equal.

[0008] Furthermore, the number of telescopic rods is at least two.

[0009] Furthermore, the telescopic rod includes a sleeve and a plug plate. One end of the sleeve is hinged in the hinge seat. The plug plate extends from one side of the support plate. One end of the plug plate is embedded in the sleeve. The plug plate and the sleeve are pressed and fixed together by bolts fasteners that pass through the sleeve.

[0010] Furthermore, both the bolt fastener and the threaded rod are provided with a rotating handle at one end.

[0011] The beneficial effects of this utility model are reflected in: (1) In this utility model, adjustable positioning pressure roller assemblies are set on both sides of the frame. By adjusting the angle of the movable plate, the cylindrical surface and conical surface on the pressure roller can be used to meet the pressing and positioning requirements of different types of fabrics.

[0012] (2) When the movable plate is raised and the threaded rod is inserted into the upper hole, the conical surface of the pressure roller is made to fit against the fabric on the feeding table. When the conical pressure roller rotates, it will generate a lateral force on the fabric, which helps to unfold the wrinkles and improve the flatness of the fabric. It is especially suitable for thin or easily rolled fabrics. Compared with the cylindrical pressure roller, it avoids further wrinkling of the rolled fabric, thus effectively ensuring the quality of subsequent heat transfer printing.

[0021] Please see the appendix Figure 1-6This embodiment provides an automatic fabric feeding device for heat transfer printing of fabric, including a conveyor table 2 set at one end of a heat transfer machine 1. The conveyor table includes a frame 3 and a feeding table 4 horizontally set at the upper end of the frame. The top of both sides of the frame 3 are symmetrically provided with positioning pressure roller assemblies 10 for flattening the fabric and the two sides of the transfer film. The positioning pressure roller assembly 10 includes a hinge seat 5, a support plate 6, a movable plate 7 and a pressure roller 8. The hinge seat 5 is set at the top of one side of the frame 3. One side of the support plate 6 is hinged to the hinge seat 5 through a telescopic rod 9. The other side of the support plate 6 has a notch 61 for accommodating the movable plate 7. The pressure roller 8 is rotatably set on the side of the movable plate 7 near the support plate 6. The shaft end 83 of the pressure roller 8 is rotatably set on the upper surface of the movable plate 7 through a rotating seat 84, and the shaft end 83 of the pressure roller 8 is parallel to the surface of the movable plate 7. The pressure roller 8 includes a conical portion 82 and a cylindrical portion 81 distributed on the left and right sides, wherein the cylindrical portion 81 is located at one end near the shaft end 83, and the conical portion 82 is located at one end near the support plate 6.

[0022] Both ends of the support plate 6 are provided with fixing blocks 63, and both ends of the movable plate 7 are provided with positioning blocks 71 corresponding to the positions of the fixing blocks 63. A pin 64 is horizontally provided on one side of the fixing block 63. One end of the pin 64 is horizontally embedded in the pin hole 711 on the positioning block 71 and rotatably connected thereto. A threaded rod 65 is horizontally threaded through the other side of the fixing block 63, and each positioning block 71 is provided with two insertion holes for accommodating the threaded rod 65. By rotating the threaded rod 65, one end of the threaded rod 65 extends into the insertion hole, thereby positioning the movable plate 7 by the support plate 6.

[0023] When the threaded rod 65 is inserted into one of the holes, the cylindrical part 81 of the pressure roller 8 is fitted against the surface of the fabric feeding table 4. At this time, the cylindrical part 81 of the pressure roller 8 applies uniform pressure to the side of the fabric to ensure that the fabric is conveyed flat and avoids wrinkles or slippage. It is suitable for flat, thick, and low-elasticity fabrics.

[0024] When the movable plate 7 is raised and the threaded rod 65 is inserted into another socket, the conical part 82 of the pressure roller 8 is fitted against the surface of the fabric feeding table 4. Because the linear velocities of the two ends of the conical part 82 of the pressure roller 8 are different, that is, the linear velocity of the large end is fast and the linear velocity of the small end is slow, the fabric will move towards the side with the slower linear velocity (small end). As a result, when the pressure roller 8 rotates under the action of the fabric, it will generate a lateral force on the fabric, which helps to unfold slight wrinkles, especially suitable for thin or easily rolled elastic fabrics.

[0025] In this embodiment, a plurality of grooves 62 for accommodating the two ends of the pressure roller 8 are respectively provided on the adjacent side of the support plate 6 and the movable plate 7. The grooves 62 are rectangular in shape, and the grooves 62 on the support plate 6 and the movable plate 7 are corresponding in position and symmetrically distributed.

[0026] In this embodiment, the pin hole 711 on the positioning block 71 is located on one side near the bracket plate 6, and the two insertion holes are located on the other side. The straight-line distance between the two insertion holes and the pin hole 711 is equal. One of the insertion holes is located on the horizontal side of the pin hole 711 and is called the upper insertion hole 712. The other insertion hole is located below the side of the pin hole 711 and is called the lower insertion hole 713. When the threaded rod 65 is inserted into the upper insertion hole 712, the movable plate 7 is in a horizontal state and the fabric is pressed by the cylindrical part 81 of the pressure roller 8. When the threaded rod 65 is inserted into the lower insertion hole 713, both the movable plate 7 and the pressure roller 8 are in an inclined state. At this time, the pressure roller 8 presses the fabric by the conical part 82.

[0027] In this embodiment, there are two telescopic rods 9. Each telescopic rod 9 includes a sleeve 91 and a plug plate 92. One end of the sleeve 91 is hinged in the hinge seat 5. The plug plate 92 extends from one side of the support plate 6. One end of the plug plate 92 is embedded in the sleeve 91. The plug plate 92 and the sleeve 91 are pressed and fixed together by bolts 93 that pass through the sleeve 91. By adjusting the length of the telescopic rod 9, it can adapt to fabrics of different widths. In this embodiment, both the bolt fastener and the threaded rod 65 are provided with a rotating handle at one end for quick adjustment.

[0028] The above description is merely a preferred embodiment of this utility model, but the scope of protection of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be determined by the scope of the claims.
