[0038] As an example, the pressure release mechanism 10 is disposed in a support frame 40, and the support frame 40 can be fixedly mounted on a machine platform, such as Figure 1 and Figure 2As shown, the support frame 40 may include two square frames spaced apart in the vertical direction, a driven roller 30 may be movably mounted in the support frame 40, and the pressure-release mechanism 10 is connected to the driven roller 30, and is used to drive the driven roller 30 to move in the support frame 40.

The pressure-release roller 101 includes a roller shaft portion 1011 and pressure-release portions 1012 extending from both ends of the roller shaft portion 1011, and a notch 1013 is provided on the pressure-release portion 1012 in the radial direction, the bottom surface of the notch 1013 is a plane, and the portion of the pressure-release portion 1012 without the notch 1013 is a cylindrical surface. The separation roller 101 is arranged on one side of the separation rod 102 and abuts against the separation rod 102. For example, the separation roller 101 can be arranged above the separation rod 102. Under the action of gravity, the separation portion 1012 of the separation roller 101 abuts against the separation rod 102. Specifically, the notch plane of the separation portion 1012 can abut against the separation rod 102. After the separation roller 101 is rotated, the cylindrical surface of the separation portion 1012 abuts against the separation rod 102.

[0039] In this example, by setting up the off-pressure roller 101 and the off-pressure rod 102 and utilizing the interaction force between the off-pressure roller 101 and the off-pressure rod 102, the driven roller 30 connected to the off-pressure roller 101 can be easily driven to move, thereby solving the problem of the inconvenience of the driven roller 30 moving in the support frame 40.

[0040] In one embodiment, the pressure-release mechanism 10 also includes an adjusting handle 103; one end of the adjusting handle 103 is fixedly connected to one end of the pressure-release roller 101, and is used to drive the pressure-release roller 101 to rotate when the adjusting handle 103 rotates, so that the pressure-release rod 102 is transferred from abutting against the notch plane to abutting against the cylindrical surface, or the pressure-release rod 102 is transferred from abutting against the cylindrical surface to abutting against the notch plane.

[0041] As an example, the pressure-releasing mechanism 10 further includes an adjustment handle 103, which is perpendicularly arranged to the pressure-releasing roller 101, and one end of the adjustment handle 103 is fixedly connected to one end of the pressure-releasing roller 101. When the adjustment handle 103 is rotated, the pressure-releasing roller 101 can be driven to rotate, so that the pressure-releasing rod 102 is transferred from abutting against the notch plane of the pressure-releasing portion 1012 to abutting against the cylindrical surface of the pressure-releasing portion 1012, or the pressure-releasing rod 102 is transferred from abutting against the cylindrical surface of the pressure-releasing portion 1012 to abutting against the notch plane of the pressure-releasing portion 1012, thereby driving the driven roller 30 to move.

[0042] In one embodiment, the pressure-release mechanism 10 also includes a pressure regulating component 104; the pressure regulating component 104 is assembled on the support frame 40; one end of the pressure-release roller 101 is connected to the driven roller 30 through the first fixed block 50, and one end of the pressure regulating component 104 abuts against the first fixed block 50, for adjusting the abutment force between the first fixed block 50.

[0043] As an example, the off-pressure mechanism 10 further includes a pressure regulating component 104. The pressure regulating component 104 is fixedly mounted on the support frame 40, one end of the off-pressure roller 101 is connected to the driven roller 30 through the first fixed block 50, and one end of the pressure regulating component 104 abuts against the first fixed block 50, and while the first fixed block 50 is fixed in the support frame 40, the abutting force between the support frame 40 or other components in the support frame 40 and the first fixed block 50 can be adjusted to clamp and fix the driven roller 30, and the clamping force on the driven roller 30 can be adjusted.

[0044] In one embodiment, the pressure adjustment assembly 104 includes a pressure rod 1041 and an adjustment member 1042; the pressure rod 1041 is used to be installed on the support frame 40; the adjustment member 1042 is inserted into the pressure rod 1041 and connected to the pressure rod 1041; one end of the adjustment member 1042 passes through the pressure rod 1041 and abuts against the first fixed block 50.

[0045] As an example, the pressure adjustment assembly 104 includes a pressure rod 1041 and an adjustment member 1042. The pressure rod 1041 is arranged on one side of the pressure roller 101. For example, the pressure rod 1041 can be arranged above the pressure roller 101. The pressure rod 1041 is fixedly connected to the support frame 40. The adjustment member 1042 is passed through the pressure rod 1041 and connected to the inner wall of the pressure rod 1041. One end of the adjustment member 1042 passes through the pressure rod 1041 and abuts against the first fixed block 50. By adjusting the length of the portion of the adjustment member 1042 passing through the pressure rod 1041 The degree can be used to adjust the abutment force between the adjusting member 1042 and the fixed block 50, so as to lock and fix the fixed block 50. For example, the adjusting member 1042 can be a screw, which can be inserted into the pressure rod 1041 in a direction perpendicular to the pressure rod 1041 and form a threaded fit with the inside of the pressure rod 1041. The first end of the screw passes through the pressure rod 1041 and abuts against the first fixed block 50. When the screw is rotated, the length of the part of the screw passing through the pressure rod 1041 can be adjusted to adjust the abutment force between the screw and the first fixed block 50.

[0046] In one embodiment, the pressure regulating assembly 104 further includes a buffer member 1043 ; a first end of the buffer member 1043 abuts against one end of the regulating member 1042 , and a second end of the buffer member 1043 abuts against the first fixing block 50 .

[0047] As an example, the pressure adjustment assembly 104 further includes a buffer 1043. The buffer 1043 may be a spring, one end of which abuts against one end of the adjustment member 1042, and the second end of which abuts against the first fixed block 50. When the adjustment member 1042 is adjusted to extend the length of the portion of the adjustment member 1042 that passes through the screw rod, the adjustment member 1042 compresses the spring, and the spring converts a portion of the pressure of the adjustment member 1042 into an abutting force between the adjustment member 1042 and the first fixed block 50, thereby preventing the abutting force between the adjustment member 1042 and the first fixed block 50 from being too large to damage the adjustment member 1042 or the first fixed block 50.

[0048] An embodiment of the utility model also provides a traction device, including an active roller 20, a driven roller 30, a support frame 40 and the pressure-release mechanism 10 in any of the above embodiments; the active roller 20 and the driven roller 30 are arranged in the support frame 40 with an interval; the pressure-release mechanism 10 is connected to both ends of the driven roller 30, and is used to drive the driven roller 30 to move toward or away from the active roller 20.

[0049] As an example, the traction device includes an active roller 20, a driven roller 30, a support frame 40, and a pressure-release mechanism 10 in any of the above examples. The active roller 20 can be fixedly installed in the support frame 40, and the driven roller 30 can be movably installed in the support frame 40 and spaced apart from the active roller 20, so that a receiving space for accommodating the passage of materials is formed between the roller surface of the active roller 20 and the roller surface of the driven roller 30. The pressure-release mechanism 10 is connected to both ends of the driven roller 30, and can drive the driven roller 30 to move in a direction close to the active roller 20 to reduce the receiving space and clamp the materials passing through the receiving space, or drive the driven roller 30 to move in a direction away from the active roller 20 to expand the receiving space, so as to facilitate the operator to adjust the materials in the receiving space.

[0050] In this example, by providing the pressure-releasing mechanism 10 in the traction device, the operator can be assisted to easily move the driven roller 30 to expand the accommodation space between the driven roller 30 and the active roller 20, making it convenient for the operator to adjust the material in the accommodation space.

[0055] In one embodiment, the traction device further includes a driving motor 80 ; the output shaft of the driving motor 80 is drivingly connected to the active roller 20 to drive the active roller 20 to rotate.

[0057] The embodiment of the utility model further provides a label making device, comprising a machine platform and a traction device in any of the above embodiments arranged on the machine platform for traction and transmission of materials.
