[0001] The utility model relates to the technical field of packaging bag production and processing, in particular to packaging bag cutting equipment. Background Art

[0002] The utility model patent currently with the announcement number CN221623177U discloses a trimming device for packaging bag production. This patent can cut the edges of various packaging bag films. Its main working principle is that a support rod is horizontally arranged on the operating table, and an adjustment frame is slidably arranged on the support rod. The adjustment frame is sleeved on the outside of the support rod and a fixed plate for pressing on the surface of the support rod is arranged inside the adjustment frame. When the trimming tool needs to move, the pull plates on the front and rear sides of the support rod can be pulled. The pull plates can make the two fixed plates inside the support rod leave the support rod, that is, the adjustment frame can move on the support rod with the trimming tool.

[0003] The inconvenience of using this structure is that when the staff needs to move the position of the trimming tool, the two arms need to pull the two pull plates one back and one back, and move the adjustment frame left and right. Combined with the conventional size first-level structure of the operating table in actual operation, the staff needs to pull the pull plates one back and one back with their arms while walking along the extension direction of the support rod, which is more laborious and inconvenient for the human arms to apply force to the pull plates. Utility Model Content

[0004] The utility model provides a packaging bag cutting device, which solves the above problems existing in the use process of the prior art.

[0005] The technical solution of the utility model is achieved as follows: a packaging bag cutting device includes a frame, a slide bar is fixedly provided on the frame, a mounting pile is provided on the slide bar for sliding left and right, the mounting pile is sleeved outside the slide bar and a cutting mechanism is provided at the lower end thereof, two abutting blocks are provided inside the mounting pile for sliding back and forth, the abutting blocks are respectively provided on the front and rear sides of the slide bar, a first elastic pushing member is provided inside the mounting pile for pressing the abutting block against the surface of the slide bar, a linkage block is provided on the mounting pile for sliding up and down for moving the abutting block away from the slide bar, and the linkage block is provided in linkage with the abutting block.

[0006] The utility model is further configured as follows: a first chamfer is formed between the side walls of the supporting block facing each other and the upper end surface of the supporting block, a push rod is fixedly provided at both front and rear ends of the linkage block, a second chamfer is formed between the side walls of the push rod facing away from each other and the lower end surface of the push rod, and the second chamfer is used to abut against the first chamfer.

[0007] The utility model is further configured as follows: rubber pads are fixedly provided on the side walls of the supporting blocks that are opposite to each other.

[0008] The utility model is further configured as follows: a second elastic pushing member for pushing the linkage block upward is provided in the installation pile.

[0009] The present invention is further configured such that: the first elastic pushing member and the second elastic pushing member are both springs.

[0010] The utility model is further configured as follows: the longitudinal section of the slide rod is polygonal, a through opening for the slide rod to pass through is opened in the middle of the installation pile, and the opening shape of the through opening is consistent with the longitudinal section of the slide rod.

[0011] The utility model is further configured as follows: the slitting mechanism is a slitting wheel, and the slitting wheel is rotatably arranged at the lower end of the installation pile.

[0012] In summary, the beneficial effects of the present invention are:

[0013] 1. This structure only requires the staff to control the up and down position of the linkage block while walking to change the position of the slitting mechanism. Relatively speaking, the operation process is smoother.

[0014] 2. The first chamfer on the supporting block and the second chamfer on the push rod can enable the push rod to push the supporting block away from the slide rod when the staff presses the linkage block downward, thereby changing the position of the slitting mechanism.

[0015] 3. The rubber pad can further increase the friction between the slide bar and the mounting pile, helping the mounting pile to be firmly fixed on the slide bar.

[0016] 4. The second elastic pushing member can be used to reduce the working pressure of the first elastic pushing member, further improving the service life of the second elastic pushing member.

[0017] 5. The longitudinal cross-section of the slide bar is set to a polygon, which can directly limit the installation angle of the mounting pile on the slide bar, which is conducive to the slitting wheel to slit the packaging bag at a fixed working position during operation.

[0022] The following is a combination of the appended examples of the present invention Figure 1-2 , clearly and completely describes the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0023] Example:

[0024] like Figures 1 to 2 As shown, the utility model discloses a packaging bag slitting device, including a frame 1, a slide rod 11 is fixedly provided on the frame 1, and a mounting pile 21 is slidably provided on the slide rod 11 to the left and right. The mounting pile 21 is sleeved outside the slide rod 11 and a slitting mechanism is provided at the lower end thereof. The slitting mechanism is a slitting wheel 29, and the slitting wheel 29 is rotatably provided at the lower end of the mounting pile 21.

[0025] like Figure 2 As shown, a supporting block 22 is provided inside the mounting pile 21 on both sides of the front and rear sides of the slide rod 11 for sliding back and forth. At the same time, a first elastic pushing member 23 is also provided in the mounting pile 21 for pushing the supporting block 22 toward the slide rod 11. Through this structure, the first elastic pushing member 23 is used to press the supporting block 22 against the surface of the slide rod 11 one front and one back, thereby generating friction between the supporting block 22 and the slide rod 11, and thereby preventing the mounting pile 21 from being displaced on the slide rod 11.

[0026] In addition, a linkage block 24 is provided on the mounting pile 21 for sliding up and down to move the abutting block 22 away from the slide rod 11. The linkage block 24 is linked with the abutting block 22. When the linkage block 24 moves downward, the abutting block 22 moves away from the mounting pile 21. Specifically:

[0027] A first chamfer 221 is formed between the side walls of the supporting block 22 facing each other and the upper end surface of the supporting block 22. At the same time, push rods 25 are fixedly extended downward at both the front and rear ends of the linkage block 24. The push rod 25 is located above the supporting block 22, and a second chamfer 251 is formed between the side walls of the push rod 25 facing away from each other and the lower end surface of the push rod 25. In this structure, the second chamfer 251 is used to abut against the first chamfer 221. In addition, a second elastic pushing member 27 for pushing the linkage block 24 upward is provided in the mounting pile 21.

[0028] The working principle of the above structure is: when the position of the slitting wheel 29 needs to be moved, the linkage block 24 can be pressed downward first, and the push rod 25 on the linkage block 24 can push the supporting block 22 to slide away from the sliding rod 11. At this time, the mounting pile 21 can be moved, such as Figure 2 As shown, because there is a connection between the linkage block 24 and the mounting pile 21, the linkage block 24 can be directly pushed at this time, and the linkage block 24 will move together with the mounting pile 21 and the slitting wheel 29 installed on the mounting pile 21. When the slitting wheel 29 moves to the ideal position, the linkage block 24 is released, and the second elastic pusher 27 pushes the linkage block 24 to move upward. At this time, the push rod 25 no longer squeezes the abutting block 22, and the abutting block 22 is also pressed against the surface of the slide rod 11 again under the action of the first elastic pusher 23, so the position of the mounting pile 21 is fixed again.

[0029] Rubber pads 26 are fixedly provided on the side walls of the abutting block 22 that face each other. This structure can further increase the friction between the mounting pile 21 and the sliding rod 11 .

[0030] The first elastic pushing member 23 and the second elastic pushing member 27 are both springs.

[0031] The longitudinal section of the slide rod 11 is polygonal, and a through hole 28 for the slide rod 11 to pass through is opened in the middle of the mounting pile 21. The opening shape of the through hole 28 is consistent with the longitudinal section of the slide rod 11. This structure can be used to directly fix the installation angle of the slitting wheel 29.

[0032] It should also be pointed out that the terms indicated in the present invention, such as: "front", "rear", "vertical", "horizontal", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as limiting the scope of protection of the present invention.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
