Description

Technical Field

[0001] The utility model relates to the technical field of bag making machines, in particular to a bag making machine. Background Art

[0002] A bag making machine is a machine that makes various plastic packaging bags or other material packaging bags. Its processing range is packaging bags of various sizes, thicknesses and specifications of plastics or other materials. Generally speaking, plastic packaging bags are the main products. When the bag making machine changes the production size, it is also necessary to change the limit device at the front end of the device. The existing bag making machine limit device is mostly two sets of rubber rings on the sliding rod to limit the raw materials. In order to ensure the stability of production, the friction between the rubber ring and the sliding rod is generally large. By changing the distance between the two sets of rubber rings, it can adapt to production needs.

[0003] The existing technology has the following problems:

[0004] After extensive searching, it was found that Chinese Patent Publication No.: CN219276826U discloses a bag making machine, including a mounting base and a bag making machine body, wherein the bag making machine body is located at the rear side end of the top of the mounting base, and mounting frames are symmetrically arranged at both ends of the front side of the top of the mounting base, and a sliding rod is arranged between the two groups of mounting frames, and two groups of limit blocks are slidably arranged on the sliding rod, and a driving member is arranged in the inner cavity of the mounting frame, and a moving member is arranged on the output end of the driving member. In the production process of plastic bags, this patent sets a limiting device at the front side end of the device to prevent the plastic bag raw materials from deviating, so as to limit the plastic bags from deviating during transportation. When the width of the plastic bags to be produced changes, it is necessary to adjust the limit block at the front end of the device to adapt to the production needs, and the limit block is driven to move by the lead screw thread block structure, and the motor is used as the power source instead of manual operation, thereby improving the work efficiency.

[0005] However, the above patent still has problems that need to be improved when adjusting the limit device set at the front end of the bag making machine according to the production needs of plastic bags. The most obvious one is that it is difficult to grasp and judge the spacing between the limit devices, resulting in the problem that the spacing between the limit devices cannot match the actual production needs of plastic bags.

[0006] Therefore, we propose a bag making machine to solve the above-mentioned drawbacks. Utility Model Content

When the servo motor 9 drives the forward and reverse screws 10 to rotate forward, the two limit members 6 are driven to approach each other. On the contrary, when the servo motor 9 drives the forward and reverse screws 10 to rotate reversely, the two limit members 6 are driven to move away from each other, so as to achieve the purpose of adjusting the distance between the two limit members 6. It should be noted that this structure is a common screw thread block structure on the market.

[0025] In this embodiment: a control panel 14 is fixedly mounted on the surface of the bracket 2 , and the control panel 14 is electrically connected to the servo motor 9 via a wire.

[0026] Specifically, it is a common circuit connection structure, which will not be described in detail here.

[0034] Working principle: When in use, in the production process of plastic bags, in order to prevent the plastic bag raw materials from deviating, a limiting device will be set at the front side end of the device to limit the plastic bags from deviating during transportation. When the width of the plastic bags to be produced changes, it is necessary to adjust the distance between the limiting members 6 at the front end of the device to meet the production needs. The control panel 14 is used to control the forward and reverse rotation of the servo motor 9. When the servo motor 9 drives the forward and reverse screws 10 to rotate forward, the two limiting members 6 are driven to approach each other. Conversely, when the servo motor 9 drives the forward and reverse screws 10 to reverse, the two limiting members 6 are driven away from each other, thereby achieving the purpose of adjusting the distance between the two limiting members 6. It should be noted that this structure is a common screw thread block structure on the market, and its working principle and structure are commonplace and well-known, so no further elaboration is required here. By setting the scale line 5 and the pointer 7, when the limit device set at the front end of the bag making machine is adjusted according to the production needs of the plastic bags, it can play an effect of grasping and judging the spacing between the limit devices, which is beneficial to accurately adjust the spacing between the limit devices according to the production needs of the plastic bags. Secondly, by setting the magnifying glass 8, it is convenient for the staff to magnify the scale on the scale line 5, which is beneficial for the staff to read the numbers, improves the convenience and accuracy of the readings, and reduces the probability of reading the wrong values.

[0035] It should be noted that the model and specifications of the servo motor 9 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0036] The power supply and principle of the servo motor 9 are clear to those skilled in the art and will not be described in detail here.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
