When reaching the specified position, turn the handle 3234, and the eccentric wheel 3233 pushes the top rod 3235 to move, thereby causing the locking block 3231 to abut against the guide rod 34, forming a strong friction force to limit the guide rod 34; and by adjusting the adjusting bolt, the third mounting plate 42 can be driven to deflect, thereby deviating from the transverse seal assembly 21 to avoid interference with the transverse seal assembly 21; finally, rotate the bolt handle 2263 to disengage from the base 22, so that the movable plate 2261 is in a loose state, and the transmission belt between the power unit 225 and the transverse seal assembly 21 can be easily removed.

[0037] The implementation principle of this embodiment is as follows: by designing the transverse seal assembly 21 to be detachably mounted on the base 22, and arranging positioning blocks and fastening bolts on the base 22, the transverse seal assembly 21 can be quickly disassembled and assembled; at the same time, the guide rod 34 and the locking device 213 of the packaging material conveying device 3 are designed so that when the transverse seal assembly 21 is disassembled, the first conveying roller 35 can automatically move away from the transverse seal assembly 21, avoiding the impact on the packaging material, and the material blocking device 4 is rotatable, and by adjusting the bolt installation angle, the impact when disassembling the transverse seal assembly 21 is also avoided. This design not only improves the maintenance convenience of the packaging machine, but also significantly shortens the downtime caused by disassembling the transverse seal device 2, and improves the overall work efficiency.

[0038] Embodiment 2 Reference Figures 10-12The present embodiment discloses a packaging machine with a quick-release transverse sealing device, which is different from the above-mentioned embodiment in that: a return spring 341 is sleeved on the guide rod 34; a guide rail 2111 is provided at the bottom of the fixed block 211; a sliding opening is provided in the base 22, in which a laterally arranged push rod 5 is slidably connected, and a sliding pin 51 adapted to the guide rail 2111 is installed on the push rod 5 by bolt fastening; the sliding pin 51 is slidably connected in the guide rail 2111, and a pulley 511 is provided on the sliding pin 51 to reduce resistance; a vertically arranged lever 52 is provided at the end of the push rod 5 away from the base 22, and in order to enhance the structural strength between the push rod 5 and the lever 52, a diagonal brace 523 is welded between the push rod 5 and the lever 52 to form a stable triangular structure.

[0039] like Fig.13 As shown, the upper part of the lever 52 is provided with a first lever pin 521; the side of the mounting seat of the first conveying roller 35 is provided with a second lever pin 522 that abuts against the lever, and the third mounting plate 42 is provided with an oblique guide hole 425, in which the first lever pin 521 is slidably connected; when the lever 52 moves away from the base 22, the lever 52 pushes the first conveying roller 35 away from the transverse sealing assembly 21 through the second lever pin 522, and pushes the third mounting plate 42 to rotate and deviate from the transverse sealing assembly 21 through the first lever pin 521. This design enables the first conveying roller 35 and the third mounting plate 42 to quickly detach from the transverse sealing assembly 21 when the transverse sealing assembly 21 is disassembled, thereby avoiding damage to the packaging material.

[0040] like Figures 14 and 15 As shown, when disassembling and assembling the transverse sealing assembly 21, no matter whether the fixed block 211 moves into the base 22 or out of the base 22, the guide rail 2111 provided at the bottom of the fixed block 211 will drive the push rod 5 to move in a direction away from the base 22 within a certain distance, and there is no need to manually adjust the material conveying device 3 and the material blocking device 4. The material conveying device 3 and the material blocking device 4 can be automatically moved away from the transverse sealing assembly 21 under the action of the lever 52.

[0041] The implementation principle of this embodiment is as follows: the reset spring 341 can make the guide rod 34 automatically return to its original position after movement, thereby improving the convenience of operation; the abutment column cooperates with the guide plate to ensure that the fixed block 211 stably pushes the guide plate to move during the sliding process; the design of the guide rail 2111 makes the movement path of the guide plate more precise and controllable; the linkage design of the push rod 5 and the first push pin 521 can effectively push the first conveying roller 35 away from the transverse sealing assembly 21 when disassembling the transverse sealing assembly 21, thereby avoiding obstruction of the disassembly and assembly process; at the same time, the first push pin 521 is used to push the third mounting plate 42 to rotate, thereby further ensuring that the distance between the material conveying device 3 and the transverse sealing assembly 21 is increased, automatically avoiding interference and preventing misoperation, thereby achieving rapid disassembly and assembly and improving production efficiency.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the technical solutions of the embodiments of the present application.
