Description

Technical Field

[0001] This utility model relates to an automatic adjustment device for hand-held conveyor, belonging to the technical field of paper bag manufacturing equipment. Background Technology

[0002] Current paper bag conveying technology typically involves the paper bag being woven by a paper bag machine and cut in half. The left hand bag is then conveyed via guide plates and multiple guide rollers to the upper hand bag operating side box and attached to the paper bag base. The right hand bag is conveyed via separating rollers and guide rollers to the upper hand bag machine transmission side box and attached to the paper bag base. When the specifications of the paper bags being woven by the machine are changed, the position of the transmission side box needs to be adjusted according to the different specifications of the paper bags, as the position of the operating side box remains unchanged. This causes the right hand bag at the hand bag conveyor to become loose or tight. At this time, the tightness of the hand bag needs to be adjusted, otherwise subsequent weaving cannot proceed. However, current paper bag machines are not very easy to adjust the tightness of the hand bag, making subsequent paper bag weaving inconvenient. Summary of the Invention

[0003] The purpose of this utility model is to provide an automatic adjustment device for hand-held conveyors, which solves the technical defects in the prior art where the tightness of the hand-held mechanism is not easy to adjust, and it is inconvenient for subsequent manufacturing when the specifications of paper bags are changed.

[0004] To solve the above problems, the technical solution adopted by this utility model is: an automatic adjustment device for hand-held conveyors, including a frame, guide roller shaft, paper separating wheel, left hand-held guide structure, and right hand-held guide structure. The frame is fixed on the hand-held conveyor and includes a left column, a right column, a first crossbar, and a second crossbar. The two ends of the first crossbar are fixedly connected to the middle of the left and right columns, respectively. The two ends of the second crossbar are fixedly connected to the top of the left and right columns, respectively. The two ends of the guide roller shaft are connected to the left and right columns, respectively. The guide roller shaft is located below the first crossbar. A guide roller is rotatably mounted on the guide roller shaft. The paper separating wheel is rotatably mounted on the first crossbar. A first guide roller is fixedly mounted on the paper separating wheel and rotates coaxially with it. The paper strip with the hand-held handle attached to the hand-held conveyor passes around the guide roller and is cut into left and right hand-held handles by the paper separating wheel. The left hand-held guide structure includes a second guide roller, a third guide roller, and a fourth guide roller. The second guide roller is rotatably mounted on the left column. The third guide roller is fixedly mounted on the left column. The paper roller and the fourth guide roller are rotatably mounted on the right side of the frame. The left handle successively passes around the second, third, and fourth guide rollers to one end of the drive-side housing. The right handle guide structure includes a seventh guide roller 13, which is rotatably mounted on the second crossbar. The right handle passes upward around the seventh guide roller 13 to the other end of the drive-side housing. The frame also includes a third crossbar, the two ends of which are fixedly connected to the left and right columns respectively. The third crossbar is located between the first and second crossbars. The right handle guide structure also includes a fifth guide roller, a guide roller mounting block, and a sixth guide roller. The fifth guide roller is rotatably mounted on the lower part of the third crossbar. The guide roller mounting block is mounted on the third crossbar and can move horizontally on the third crossbar. The sixth guide roller is rotatably mounted on the guide roller mounting block and moves synchronously with the guide roller mounting block. The right handle passes around the fifth and sixth guide rollers before passing around the seventh guide roller. This utility model is equipped with a fifth guide wheel and a sixth guide wheel. By moving the sixth guide wheel, the tightness of the handle can be adjusted. This allows the tightness of the handle to be adjusted according to the change of paper bag specifications. When the position of the transmission side box changes due to the adjustment of paper bag specifications, the tightness of the handle can be adjusted, which facilitates subsequent manufacturing.

[0005] As a further improvement of this utility model, it also includes a linear guide rail and a cylinder. The linear guide rail is fixedly mounted on the third horizontal bar in the left-right direction. The guide wheel mounting block is set on the linear guide rail and forms a horizontal moving pair with the linear guide rail. The cylinder is mounted on the third horizontal bar, and its piston rod is set in the horizontal direction and connected to the guide wheel mounting block. The extension and retraction of the piston rod of the cylinder is used to drive the guide wheel mounting block to move horizontally. This utility model, through the linear guide rail and the cylinder, can drive the sixth paper guide wheel to move, realize the automatic adjustment of the sixth paper guide wheel, and improve the automation level of paper bag manufacturing.

[0006] As a further improvement of this utility model, it also includes an adjusting arm and an adjusting drive structure. The upper end of the adjusting arm is rotatably connected to the right column, and the fourth paper guide wheel is rotatably mounted on the lower end of the adjusting arm. The adjusting drive structure is mounted on the right column and connected to the adjusting arm, and is used to drive the adjusting arm to swing.
