Technical Field
[0001] This utility model relates to the field of bag making machine technology, specifically to a bag making machine auxiliary material conveying and adjusting mechanism. Background Technology
[0002] A bag-making machine is a machine that produces various plastic or other material packaging bags. Its processing range includes packaging bags of various sizes, thicknesses, and specifications made of plastic or other materials, with plastic packaging bags being the main product.
[0003] The earliest bag-making machines simply placed two layers of film on a continuous conveyor line, then completed the process through heat sealing and heat cutting. However, with market demand, more feature-rich bag-making machines became urgently needed. For example, the market demanded more aesthetically pleasing packaging bags, necessitating improvements to the machines. These machines needed to achieve differential speed conveying of the double-layer film and alignment of the printed areas on the double-layer film. Further market demand led to the development of a new type of bag-making machine. This machine incorporated an auxiliary material conveyor line, intersecting with the main material conveyor line, located near the beginning of the traditional processing line. This auxiliary material, which would form the sides of the packaging bag, was conveyed to the corresponding position on the film and entered the subsequent heat sealing and heat cutting process along with the film. This resulted in packaging bags with two sides, allowing them to unfold into a three-dimensional shape and effectively increasing their capacity.
[0004] However, during the auxiliary material conveying process, precise control of the conveying of auxiliary materials is required. If the position is deviated, the auxiliary materials and the main materials will be misaligned during heat sealing, resulting in the failure of the side heat sealing of the final product and affecting the quality of the final product. Therefore, a frame that can be effectively adjusted is needed to ensure that the conveying mechanism can convey the auxiliary materials to the accurate position. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides a material conveying and adjusting mechanism for a bag making machine.
[0006] The specific technical solution is as follows:
[0007] The auxiliary material conveying and adjusting mechanism for a bag-making machine includes a base, an adjusting seat, and a mounting frame arranged sequentially from bottom to top. The upper part of the base is connected to the bottom of the adjusting seat via a first linear guide rail, and the upper part of the adjusting seat is connected to the bottom of the mounting frame via a second linear guide rail. The sliding directions of the first and second linear guide rails are cross-shaped in the horizontal direction. Ball screws, namely a first ball screw and a second ball screw, are provided at the connection positions of the upper part of the base and the lower part of the adjusting seat, and at the connection positions of the upper part of the adjusting seat and the lower part of the mounting frame. The direction of the first ball screw is parallel to the direction of the first linear guide rail, and the direction of the second ball screw is parallel to the direction of the second linear guide rail. By rotating the first and second ball screws, the horizontal position of the mounting frame can be adjusted.
[0008] Furthermore, the base includes a first base plate and four vertical first side plates. The base plate is also provided with a set of parallel groove plates to improve the connection rigidity of the base. It is also provided with a set of cross-shaped reinforcing plates. The first linear guide rails are at least two sets and are respectively fixed to the upper part of a set of parallel first side plates.
[0009] Furthermore, the groove plate is also provided with a first linear guide rail, which is parallel to the first linear guide rail fixed on the first side plate.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. The described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0020] In the relevant existing technologies, the conveying of auxiliary materials requires precise control. If the position is deviated, the auxiliary materials and the main materials will be misaligned during heat sealing, resulting in the failure of the side heat sealing of the final product and affecting the quality of the final product. Therefore, a frame that can be effectively adjusted is needed to ensure that the conveying mechanism can convey the auxiliary materials to the accurate position.
[0021] To address the problems existing in the relevant prior art, this utility model proposes an auxiliary material conveying and adjusting mechanism for a bag making machine. The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.
[0022] Please see Figures 1 to 3 This utility model proposes an auxiliary material conveying and adjusting mechanism for a bag making machine, specifically including a base 1, an adjusting seat 2, and a mounting frame 3 arranged sequentially from bottom to top. The upper part of the base 1 is connected to the bottom of the adjusting seat 2 via a first linear guide rail 4, and the upper part of the adjusting seat 2 is connected to the bottom of the mounting frame 3 via a second linear guide rail 5. The sliding directions of the first linear guide rail 4 and the second linear guide rail 5 are cross-shaped in the horizontal direction. Ball screws are provided at the connection positions of the upper part of the base 1 and the lower part of the adjusting seat 2, and at the connection positions of the upper part of the adjusting seat 2 and the lower part of the mounting frame 3, namely a first ball screw 6 and a second ball screw 7. The direction of the first ball screw 6 is parallel to the direction of the first linear guide rail 4, and the direction of the second ball screw 7 is parallel to the direction of the second linear guide rail 5. By rotating the first ball screw 6 and the second ball screw 7, the horizontal position of the mounting frame 3 can be adjusted.
[0023] For detailed usage, please refer to [link / reference]. Figure 4In the figure, 11 is the position of the unwinding mechanism, and 12 is the subsequent slitting section. The main material is conveyed along the main material direction. The auxiliary material unwinding and cutting conveying mechanism is fixed on the mounting frame 3 and completes the cutting and conveying of the auxiliary material and aligns it with the main material. Then, the auxiliary material is conveyed together with the main material to complete the subsequent slitting and heat sealing work. The overall auxiliary material conveying position needs to be accurately aligned with the main material, so the conveying of the auxiliary material needs to be adjusted. At this time, the first ball screw 6 and the second ball screw 7 can be adjusted so that the auxiliary material unwinding mechanism installed on the mounting frame 3 can be adjusted in the horizontal direction to achieve the purpose of calibrating and aligning with the main material. Specifically, the driving mechanism for driving the first ball screw 6 and the second ball screw 7 can be a motor, or a manual adjustment method using handwheels can be used, that is, handwheels are set at the ends of the first ball screw 6 and the second ball screw 7.
[0024] Please refer to details. Figure 2 and Figure 3 The base 1 includes a first base plate 1a and four vertical first side plates 1b. The first base plate 1a is also provided with a set of parallel groove plates 1c to improve the connection rigidity of the base 1. It is also provided with a set of cross-shaped reinforcing plates 1d. There are at least two sets of first linear guides 4, which are respectively fixed on the upper part of a set of parallel first side plates 1b. The groove plates 1c are also provided with first linear guides 4, which are parallel to the first linear guides 4 fixed on the first side plates 1b. The adjusting seat 2 includes a second base plate 2a and four vertical second side plates 2b. Multiple second linear guides are provided on a set of parallel second side plates. Through the above settings, planar sliding can be effectively realized, and the sliding stability can prevent shaking, thus ensuring the stability of each component on the mounting frame.
[0025] Specifically, there must be at least one first ball screw 6 and one second ball screw 7. The exact number of first ball screws 6 and second ball screws 7 is selected according to the actual situation. When the distance between the two first linear guides 4 is large, two or more sets of first ball screws 6 can be set to rotate synchronously to ensure stable drive and prevent jamming. When the distance between the two first linear guides 4 is small, setting one first linear guide 6 will not easily cause jamming. The requirements for setting the second ball screw 7 are the same.
[0026] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
