[0007] A clamping component is arranged inside each of the triangular plates. A fixed shaft is clamped and installed between the two triangular plates, and a feeding drum is rotatably connected to the outside of the fixed shaft.

[0008] Through the above technical solutions, by arranging a block installation component between the head bottom plate and the triangular plate, the triangular plate can be quickly installed on the head bottom plate, getting rid of the traditional screw installation method. It is not only convenient to replace the feeding drum, but also the disassembly and assembly operation can be completed without repeatedly turning the screws, greatly improving the disassembly and assembly efficiency. At the same time, the downtime is reduced, and the working efficiency of the three-dimensional packaging machine is also improved, which is conducive to practical applications.

[0009] Preferably, the quick - installation component includes a limit groove, a limit block, a limit hole, a sliding groove, a sliding plate, a spring and a limit rod. The limit grooves are opened at both ends of the top and bottom of the machine head bottom plate. The limit blocks are installed at the top and bottom of the triangular plate. The limit blocks are slidably connected to the corresponding limit grooves. The limit holes are opened at both ends of the machine head bottom plate. The sliding grooves are opened on the sides of the two triangular plates away from each other. The sliding plate is slidably connected in the sliding groove. The spring is installed between the outer side of the sliding plate and the inner wall of the sliding groove. The limit rod is fixed on the side of the sliding plate away from the spring.

[0028] Refer to Figure 1 and Figure 2, an embodiment of the utility model provides a left and right triangular plate with convenient replacement, which includes a machine head bottom plate 1 and two triangular plates 2, and the two triangular plates 2 are respectively installed at both ends of the machine head bottom plate 1. Installation plates 15 are installed on both the top and bottom of the machine head bottom plate 1, and installation holes 16 are provided at both ends of the installation plate 15. By using the installation plate 15 and the installation holes 16, the machine head bottom plate 1 can be better installed on the three-dimensional packaging machine for use. Quick installation components are arranged inside the triangular plates 2, and the quick installation components are used to install the triangular plates 2 on the machine head bottom plate 1. Clamping components are arranged inside the triangular plates 2, and a fixed shaft 3 is clamped and installed between the two triangular plates 2 through the clamping components. A material discharging reel 4 is rotatably connected to the outside of the fixed shaft 3, and the material discharging reel 4 can be used for the material discharging operation of the film. By arranging a block installation component between the machine head bottom plate 1 and the triangular plate 2, the triangular plate 2 can be quickly installed on the machine head bottom plate 1, getting rid of the traditional screw installation method. It is not only convenient to replace the material discharging reel 4, but also the disassembly and assembly operation can be completed without repeatedly screwing the screws, greatly improving the disassembly and assembly efficiency. At the same time, the downtime is reduced, the working efficiency of the three-dimensional packaging machine is improved, which is beneficial to the actual application.

[0029] Refer to Figure 3 and Figure 4, in one aspect of this embodiment, the quick - installation component includes a limit groove 5, a limit block 6, a limit hole 7, a sliding groove 8, a sliding plate 9, a spring 10, and a limit rod 11. The limit groove 5 is opened at both ends of the top and bottom of the machine head bottom plate 1. The limit blocks 6 are installed at the top and bottom of the triangular plate 2. The limit blocks 6 are all slidably connected to the corresponding limit grooves 5. By using the sliding between the limit block 6 and the limit groove 5, the installation position of the triangular plate 2 can be preliminarily positioned. The limit holes 7 are opened at both ends of the machine head bottom plate 1. The sliding groove 8 is opened on the side of the two triangular plates 2 away from each other. The sliding plate 9 is slidably connected to the sliding groove 8. The spring 10 is installed between the outer side of the sliding plate 9 and the inner wall of the sliding groove 8. By using the elastic force of the spring 10, a force can be applied to the sliding plate 9 so that it always lies at one end inside the sliding groove 8 without external force. The limit rod 11 is fixed on the side of the sliding plate 9 away from the spring 10. The limit rods 11 all penetrate through the corresponding triangular plates 2 and extend into the limit holes 7. By using the cooperation between the limit rod 11 and the limit hole 7, the installation position of the triangular plate 2 can be further fixed. The ends of the limit rod 11 away from the sliding plate 9 and both ends of the machine head bottom plate 1 are provided with mutually cooperating inclined surfaces. By using the cooperation between the inclined surfaces, when installing the triangular plate 2, the inclined surface at one end of the limit rod 11 contacts the inclined surface outside the machine head bottom plate 1, and the triangular plate 2 continues to be slidably installed. Under the action of the force generated by sliding the triangular plate 2 and in cooperation with the inclined surface, the limit rod 11 can contract, and the sliding plate 9 squeezes the spring 10. When the triangular plate 2 is slidably installed to the designated position, by using the elastic force of the spring 10, the sliding plate 9 and the limit rod 11 return to their positions, and the limit rod 11 can smoothly enter the limit hole 7, thus facilitating the completion of the installation operation of the triangular plate 2.

[0030] Referring to Figure 1 and Figure 2 , in one aspect of this embodiment, the clamping component includes an installation groove 12, an adjusting screw 13, and a clamping block 14. The installation groove 12 is opened on the outside of the triangular plate 2. The adjusting screw 13 is threadedly connected to the top of the triangular plate 2. The clamping block 14 slides inside the installation groove 12. The bottom of the adjusting screw 13 extends into the installation groove 12 and is rotatably connected to the top of the clamping block 14. Both ends of the fixed shaft 3 are clamped and fixed between the bottom of the clamping block 14 and the bottom of the inner wall of the installation groove 12. By rotating the adjusting screw 13, the clamping block 14 can be driven to move up and down inside the installation groove 12, thus facilitating the clamping and loosening operations of the fixed shaft 3. The bottom of the clamping block 14 is provided with an arc - surface structure for cooperating with the fixed shaft 3. By using the arc - surface structure, the bottom of the clamping block 14 fits more closely to both ends of the fixed shaft 3, thus ensuring the clamping and fixing effect.

[0031] Working principle:

[0032] When in use, first align the limiting block 6 on a set of triangle plates 2 with the limiting groove 5 on the machine head bottom plate 1, and then slide and install the triangle plate 2. When the inclined surface at one end of the limiting rod 11 contacts the inclined surface on the outer side of the machine head bottom plate 1, and continue to slide and install the triangle plate 2, under the force generated by sliding the triangle plate 2 and in cooperation with the inclined surface, the limiting rod 11 can be retracted, and the slide plate 9 is used to squeeze the spring 10. When the triangle plate 2 is slid and installed to the specified position, the elastic force of the spring 10 is used to make the slide plate 9 and the limiting rod 11 return to their original positions, and the limiting rod 11 can smoothly enter the interior of the limiting hole 7, thereby facilitating the installation operation of the triangle plate 2.

[0033] Then, one end of the fixed shaft 3 is passed through the mounting groove 12 on the outer side of the triangular plate 2, and then the adjusting screw 13 is rotated to drive the clamping block 14 to move downward inside the mounting groove 12, thereby clamping one end of the fixed shaft 3;

[0034] At this time, slide and install the second triangle plate 2 according to the above operation, and make the other end of the fixed shaft 3 be located inside the installation groove 12 outside the triangle plate 2, and repeat the above operation, and use the clamping block 14 to clamp the other end of the fixed shaft 3;

[0035] When it is necessary to replace the fixed shaft 3 and the unloading reel 4, first turn the adjusting screw 13 to drive the clamping block 14 to move upward inside the mounting groove 12, so that the clamping block 14 no longer clamps the fixed shaft 3, and then move the slide plate 9 to squeeze the spring 10 and drive the limiting rod 11 to disengage from the limiting hole 7, and then the triangular plate 2 can be slid and removed, and the fixed shaft 3 and the unloading reel 4 can be disassembled at the same time, so that it is convenient to replace them, getting rid of the traditional screw installation method, not only making it convenient to replace the unloading reel 4, but also eliminating the need to repeatedly turn the screws to complete the disassembly and assembly operation, which greatly improves the disassembly and assembly efficiency, while reducing downtime, and also improving the working efficiency of the three-dimensional packaging machine, which is beneficial to practical applications.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
