For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] As attached Figure 1 To be continued Figure 3 As shown: This utility model provides a plastic packaging bag cutting and shaping device, including a mounting platform 1, which is square but can also be other shapes, preferably made of metal. Four support legs 2 are mounted on the bottom of the mounting platform 1, and the height of the support legs 2 can be customized according to actual usage. A first mounting plate 3 is mounted on the mounting platform 1, and a placement roller 4 is mounted on the first mounting plate 3. The placement roller 4 and the first mounting plate 3 are rotatably connected. The placement roller 4 is used to place the plastic packaging bag roll, and the slots of the placement roller 4 and the roll match. A limiting component used in conjunction with the placement roller 4 is also provided; this is prior art and will not be described in detail here. A driving component 5 is also mounted on the mounting platform 1 to drive the movement of the plastic bag on the roll. A cutting component 6 is mounted on one end of the driving component 5.

[0021] The drive assembly 5 includes a second mounting plate 501 mounted on the mounting platform 1. A motor 502 is mounted on the second mounting plate 501. The output end of the motor 502 is connected to a traction roller 503. The traction roller 503 is preferably made of plastic. A gap is left between the traction roller 503 and the mounting platform 1 to facilitate the passage of plastic bags on the roll.

[0022] In use, the plastic bag roll can be placed on the placement roller 4 and fixed. Then, the roll is placed below the traction roller 503. The motor 502 is started, which drives the traction roller 503 to start. The friction of the traction roller 503 moves the plastic bag. When the plastic bag moves to the bottom of the cutting component 6, the traction roller 503 is stopped, and the cutting component 6 is started to cut the plastic bag. At this time, the traction roller 503 can also press the plastic bag to a certain extent. The cutting length of the plastic bag can be controlled by controlling the start and stop time of the traction roller 503. This function can be achieved with simple programming, which can be implemented by those skilled in the art and will not be described in detail here. Through the above design, the plastic bag can be cut quickly and continuously, and the cutting length can be controlled, which improves practicality.

[0023] A third mounting plate 7 is mounted on the side of the first mounting plate 3, and a guide roller 8 is mounted on the third mounting plate 7. The distance between the guide roller 8 and the mounting platform 1 is the same as the distance between the traction roller 503 and the mounting platform 1. In use, the plastic bag on the material roll can be passed under the guide roller 8 and then placed under the traction roller 503, thereby reducing the pulling force of the material roll.

[0024] The traction roller 503 includes a roller body 5031, a through groove 5032 inside the roller body 5031, and a connecting rod 5033 installed in the through groove 5032. The connecting rod 5033 and the through groove 5032 are preferably square. When the connecting rod 5033 rotates, it can drive the roller body 5031 to rotate. The connecting rod 5033 is connected to the output end of the motor 502. The connecting rod 5033 has a threaded hole 5034. It also includes a screw 5035. A baffle 5036 is installed at one end of the screw 5035. When the screw 5035 rotates into the threaded hole 5034, the baffle 5036 contacts the roller body 5031. The diameter of the baffle 5036 is larger than the diameter of the connecting rod 5033, thereby blocking the roller body 5031. The baffle 5036 is provided with an insertion hole to facilitate the insertion of a wrench.

[0025] When it is necessary to replace the roller body 5031, simply use a wrench to rotate the baffle 5036, thereby driving the screw 5035 to rotate. When the baffle 5036 is removed, the roller body 5031 can be removed, and then a new roller body 5031 can be installed. Through the above design, the roller body 5031 can be replaced quickly, improving practicality.

[0026] The cutting assembly 6 includes a mounting bracket 601 mounted on a mounting platform 1. A cylinder 602 is mounted on the top of the mounting bracket 601, and a cutter 603 is mounted on the output end of the cylinder 602, extending through the top of the mounting bracket 601. When the plastic bag moves to a position below the cutter 603, the cylinder 602 can be activated, causing the cutter 603 to move and thus cut the plastic bag.

[0027] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
