Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, in particular to a printing machine for tensioning cloth. Background Art

[0002] In the prior art, a transfer printing machine generally includes a cloth feeding mechanism, a printing device, a drying device, and a rolling mechanism. When working, the cloth enters the printing device through the cloth feeding mechanism to complete the printing of the cloth. After the printing of the cloth is completed, the cloth enters the drying device through multiple cloth guide rollers to dry the cloth. After the drying is completed, the cloth enters the rolling mechanism through multiple cloth guide rollers to complete the rolling and collection of the cloth.

[0003] There are many existing technologies for tensioning fabric printing machines, such as:

[0004] Chinese patent publication number CN216272300U discloses a fabric tensioning device for a transfer printing machine, including a rotating frame and a driving member, the rotating frame includes a first roller, a second roller and two connecting rods, the two connecting rods are parallel to each other and are respectively located at the two ends of the first roller, the two connecting rods are respectively connected to the ends of the first roller, the two ends of the second roller are respectively connected to the two connecting rods, the first roller and the second roller are parallel to the width direction of the fabric, the driving member is used to be installed on the frame of the printing machine and connected to the connecting rod to drive the rotating frame to rotate in a vertical plane. The application has the effect of adjusting the tension of the fabric.

[0005] It can be seen that most printing machines for tensioning fabrics include a rotating frame and a driving member. A number of connecting rods are arranged on the rotating frame, and one end of each connecting rod is connected to the end of a roller. After the fabric passes through the roller, the driving member is used to rotate the rotating frame to adjust the tension of the fabric. However, fabrics of different sizes require rollers of different lengths. When the fabric width is greater than the length of the roller, the entire fabric tensioning device is unusable. In addition, when the fabric is tensioned, the force on the roller is huge. If the fixing of the connecting rod and the roller is a simple clamping method, the roller may be detached from the connecting rod when the fabric is tensioned.

[0006] In view of this, we propose a printing machine for tensioning fabric. Utility Model Content

[0007] The purpose of the utility model is to solve the above-mentioned shortcomings and provide a printing machine for fixing the tensioned fabric which can be adjusted according to the fabric width.

[0023] Most of the printing machines for tensioning fabrics include a rotating frame and a driving member. A number of connecting rods are arranged on the rotating frame, and one end of each connecting rod is connected to the end of a roller. After the fabric passes through the roller, the driving member is used to rotate the rotating frame to adjust the tension of the fabric. However, fabrics of different sizes require rollers of different lengths. When the fabric width is greater than the length of the roller, the entire fabric tensioning device is unusable. In addition, when the fabric is tensioned, the force on the roller is enormous. If the connecting rod and the roller are fixed by a simple clip-on method, the roller may be detached from the connecting rod when the fabric is tensioned.

[0024] like Figure 1-Figure 4 As shown, the present embodiment provides a printing machine for tensioning fabric, including a base 100, a fixed plate 110 is provided above the base 100, a slidable sliding plate 120 is provided on one side of the fixed plate 110, in consideration of adjusting the size of a roller 140, a second hydraulic rod 150 is provided on the side of the sliding plate 120 away from the fixed plate 110, the fixed plate 110 and the sliding plate 120 are both provided with a rotating assembly 130, the rotating assembly 130 includes a rotating plate 132 rotatably fixed in the fixed plate 110 and the sliding plate 120 and a sleeve 133 fixed on the rotating plate 132, in consideration of increasing the force strength of the roller 140, a slidable roller 140 is provided between the two sleeves 133.

[0025] The improvement of this embodiment lies in that a second hydraulic rod 150 is arranged on one side of the sliding plate 120, and the second hydraulic rod 150 is used for hydraulic operation to adjust the size of the roller 140 arranged between the sliding plate 120 and the fixed plate 110 for tensioning, so that the roller 140 can be adjusted according to the cloth width, thereby improving the applicability of the equipment, and the roller 140 is arranged in two sleeves 133, and the sleeve 133 fixed on the rotating plate 132 is used to cover the roller 140, so that when the cloth is tensioned, the situation of the roller 140 detaching from the equipment due to excessive force is reduced.

[0026] Considering the further adjustment of the size of the rotating roller 140 and the introduction of the rotating assembly 130 and the rotating roller 140 , a second embodiment of the present invention is shown.

[0027] A slide groove 101 is symmetrically provided on the base 100, and a fixed block 121 is symmetrically provided at the bottom of the sliding plate 120. The fixed block 121 is fixed in the slide groove 101 to slide, and the second hydraulic rod 150 that limits the sliding direction of the sliding plate 120 performs hydraulic movement to make the sliding plate 120 slide in the slide groove 101, so as to adjust the size of the roller 140. A rotating groove 111 is provided in both the fixed plate 110 and the sliding plate 120. The rotating plate 132 is fixed in the rotating groove 111 to rotate. A motor 131 is provided on one side of the rotating plate 132. The sleeve 133 is hollow. The roller 140 is fixed in the sleeve 133 to slide. Blocks 141 that limit the sliding distance of the roller 140 are fixed on both sides of the roller 140. A first hydraulic rod 134 is fixed between the rotating plate 132 and the roller 140 in the fixed plate 110. A baffle 135 is fixed on one side of the sleeve 133. The baffle 135 is used to limit the tensioning area of ​​the fabric.

[0028] In summary, the working principle of this solution is as follows:

[0029] According to the size of the cloth, the second hydraulic rod 150 is started, and the second hydraulic rod 150 performs hydraulic movement, and the sliding plate 120 slides in the slide groove 101, so that the roller 140 slides in the sleeve 133 fixed on the sliding plate 120. When one end of the roller 140 is against the bottom of the sleeve 133 on the sliding plate 120, it is still not suitable for the cloth size. At this time, the first hydraulic rod 134 is started, and the piston rod of the first hydraulic rod 134 pulls the roller 140 to move toward the fixed plate 110. The second hydraulic rod 150 is started again until the distance between the baffle 135 fixed on one side of the sleeve 133 is suitable for the cloth size, and the cloth passes through the two rollers 140 in an S-shaped route, and the motor 131 is started. The angle between the two rollers 140 is adjusted by the motor 131 until the appropriate tension is reached.
