A clamping component 6 is arranged on the top of the adjusting component 7, and the packaging paper tube is clamped by the clamping component 6 to improve the stability of the packaging paper tube.

[0034] Reference Figure 2 The clamping assembly 6 includes a support column 62, the top of the support column 62 is fixedly connected to a fixed frame 61, and a through groove is provided at the bottom of the inner wall of the fixed frame 61. The fixing effect of the fixed frame 61 prevents the fixed frame 61 from falling off. The top inner wall of the fixed frame 61 is slidably connected to a movable rod 64, and the movable rod 64 is symmetrically distributed in two groups. The sliding effect of the movable rod 64 drives the cylindrical frame 65 to move, and the outer periphery of the support column 62 is slidably connected to a shell sleeve 66. The sliding effect of the shell sleeve 66 drives the hinged rod 63 to move. The outer wall of the shell sleeve 66 is hinged with a hinged rod 63, and the hinged rod 63 is symmetrically distributed in two groups. The moving effect of the hinged rod 63 drives the movable rod 64 to slide. A limiting assembly 67 is provided on the inner wall of the shell sleeve 66, and the shell sleeve 66 is limited by the limiting assembly 67 to keep the movable rod 64 fixed.

[0035] Reference Figure 1 and Figure 3The adjusting component 7 includes a fixing plate 71, which supports and fixes the fixing block 72 through the fixing plate 71. The top of the fixing plate 71 is fixedly connected to the fixing block 72, and the inner wall of the fixing block 72 is rotatably connected to the rotating shaft 73. Through the rotation effect of the rotating shaft 73, the supporting column 62 is driven to rotate around the rotating shaft 73 as the center. The inner wall of the rotating shaft 73 is provided with a clamping component 74, and the clamping component 74 is used to limit the rotating shaft 73 so that the supporting column 62 remains fixed.

[0036] Reference Figure 2 The inner wall of the bottom end of the support column 62 is fixedly connected to the outer periphery of the rotating shaft 73, and the top end of the movable rod 64 is fixedly connected to a cylindrical frame 65.

Through the elastic force of the limiting spring 672, the limiting block 671 always maintains a clamping effect with the limiting groove 673 when not affected by external force, thereby limiting the shell sleeve 66. The outer wall of the limiting block 671 is fixedly connected with a pull rod 674, and the outer wall of the support column 62 is provided with a limiting groove 673. There are multiple groups of limiting grooves 673. Through the multiple groups of limiting grooves 673, the limiting block 671 is clamped at different positions to limit the shell sleeve 66 at different positions.

[0038] Reference Figure 3 and Figure 5 When the locking cam 742 is in the state of being lifted up, the locking cam 741 of the locking cam 74. When the locking cam 742 is in the state of being lifted up, the locking cam 741 of the locking cam 741 is in the state of being lifted up.

[0039] Reference Figure 4One end of the limit spring 672 is fixedly connected to the inner wall of the shell sleeve 66, and the other end of the limit spring 672 is fixedly connected to the outer wall of the limit block 671. The fixing effect of the limit spring 672 keeps the limit block 671 fixed to prevent the limit block 671 from falling off. The outer periphery of the pull rod 674 penetrates and is slidably connected to the inner wall of the shell sleeve 66. The sliding effect of the pull rod 674 drives the limit block 671 to slide along the inner wall of the shell sleeve 66.

[0040] Reference Figure 5 One end of the spring 742 is fixedly connected to the top inner wall of the rotating shaft 73, and the other end of the spring 742 is fixedly connected to the bottom of the block 741. The fixing effect of the spring 742 keeps the block 741 fixed to prevent the block 741 from falling off. The outer wall of the block 741 is slidably connected to the top inner wall of the rotating shaft 73. The sliding effect of the block 741 makes the block 741 and the slot 744 engage or release the engagement effect. The outer wall of the block 741 is engaged with the inner wall of the slot 744. The engagement effect of the block 741 and the slot 744 allows the ring 743 to limit the rotating shaft 73.

[0041] Reference Figure 4 The outer wall of the limit block 671 is slidably connected to the inner wall of the shell sleeve 66. Through the sliding effect of the limit block 671, the limit block 671 and the limit groove 673 are engaged or released. The outer wall of the limit block 671 is engaged with the inner wall of the limit groove 673. Through the engaging effect of the limit block 671 and the limit groove 673, the support column 62 limits the shell sleeve 66.

[0042] Working principle: When it is necessary to cut and feed the packaging paper, the staff pulls the pull rod 674 outward, and drives the limit block 671 to slide along the inner wall of the shell sleeve 66 through the pull rod 674, and at the same time releases the clamping effect with the limit groove 673, so that the shell sleeve 66 releases the limiting effect, and the staff slides the shell sleeve 66 upward along the outer wall of the support column 62, driving the hinged rod 63 to move, and drives the movable rod 64 to slide to both sides along the inner wall of the fixed frame 61 through the hinged rod 63, so that the two groups of movable rods 64 drive the two groups of cylindrical frames 65 to open.

[0043] The staff inserts one side of the packaging paper tube with the curled packaging paper into a group of cylindrical frames 65, slides the shell 66 downward, so that the hinged rod 63 drives the movable rod 64 to slide to the middle position of the fixed frame 61, so that the two groups of cylindrical frames 65 are close to each other, and the other group of cylindrical frames 65 is inserted into the other side of the packaging paper tube. The staff loosens the pull rod 674, so that the limit block 671 is engaged with the limit groove 673 under the elastic force of the limit spring 672, and the shell 66 is limited at the same time, so that the two groups of movable rods 64 remain fixed, thereby improving the stability of the packaging paper tube. The staff unwinds the packaging paper onto the electric conveyor belt 3, starts the electric conveyor belt 3, and transports the packaging paper to the bottom of the cutting knife 4 through the pressure roller 8. The electric telescopic rod 5 is started to drive the cutting knife 4 to cut the packaging paper.

[0044] When the packaging paper is too large or too small, resulting in a certain angle between the packaging paper and the electric conveyor belt 3 when unwinding, resulting in uneven transmission of the packaging paper, the staff presses the block 741 to release the clamping effect of the block 741 and the clamping slot 744, and at the same time releases the limiting effect on the rotating shaft 73. The staff rotates the rotating shaft 73 to the left, driving the support column 62 to rotate to the left, so that the packaging paper tube on the cylindrical frame 65 is in the same horizontal line with the electric conveyor belt 3. When the adjustment is completed, the block 741 is released, so that the block 741 is clamped with the clamping slot 744 under the elastic force of the spring 742, thereby limiting the rotating shaft 73 and keeping the support column 62 fixed.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
