[0022] like Figure 1 As shown, a clamping device for high-precision paper tube cutting is characterized by comprising: a base 1, a telescopic mechanism 2, and a fastening mechanism 3.

[0023] The base 1 is a cylindrical cavity shell arranged horizontally and transversely, and a circular opening is provided in the center of the left side surface of the base 1;

[0024] The telescopic mechanism 2 is horizontally arranged inside the base 1 and passes through the left side of the base 1 through the opening;

[0025] A plurality of fastening mechanisms 3 are horizontally arranged on the outer side of the base 1 . The plurality of fastening mechanisms 3 are evenly and parallelly arranged around the base 1 . The lower side of the fastening mechanisms 3 is fixed to the surface of the base 1 . The left end of the fastening mechanisms 3 is connected to the left end of the telescopic mechanism 2 .

[0026] like Figure 1 As shown, in the specific implementation of the present invention, three fastening mechanisms 3 are provided, and the angle between each fastening mechanism 3 is 120°, which is evenly distributed to ensure that the force applied by each fastening mechanism 3 to the paper tube is the same.

[0027] The utility model uses the telescopic mechanism 2 to expand the plurality of fastening mechanisms 3 outward, thereby supporting the inner wall of the paper tube and fixing the paper tube.

[0028] Preferably, the telescopic mechanism 2 includes: a cylinder, a push rod 201, and a connecting block 202; the cylinder is fixed to the right side of the inside of the base 1, the right end of the push rod 201 is fixed to the left end of the cylinder, and the left end of the push rod 201 is fixed with a connecting block 202; the connecting block 202 is a circular cylinder, and a plurality of square connecting plates A203 are radially provided on the surface of the connecting block 202; when the cylinder works normally, the push rod 201 moves left and right, and the cylinder can more accurately control the scale of contraction and expansion of the fastening mechanism 3.

[0029] Preferably, the number of connecting plates A203 is equal to the number of fastening mechanisms 3 .

[0030] Preferably, the fastening mechanism 3 includes: a clamping plate 301, a traction rod 302, and two connecting rods 303; the clamping plate 301 is horizontally arranged, two connecting plates B are provided at the center of the bottom surface of the clamping plate 301, and a connecting plate C304 is provided at the left end of the bottom surface of the clamping plate 301; one end of the traction rod 302 is fixed to the left end connecting plate C304 of the clamping plate 301 by screws, and the other end of the traction rod 302 is fixed to the connecting plate A203 of the connecting block 202 by screws; the two connecting rods 303 are arranged in parallel to ensure that the clamping plate 301 is parallel to the base 1; one end of each connecting rod 303 is connected to the base 1 by screws, and the other end is fixed to the connecting plate B of the clamping plate 301 by screws.

[0031] Preferably, a rubber layer is provided on the surface of the pressing plate 301 opposite to the base 1 .

[0032] Preferably, the surface of the rubber layer is a convex arc surface, which ensures that the pressing plate 301 fits the inner wall of the paper tube, increases the contact area between the pressing plate 301 and the inner wall of the paper tube, and thus increases the friction force.

[0033] Preferably, dense protrusions are evenly arranged on the surface of the rubber layer.

[0034] In such Figure 1 In the illustrated embodiment, when the present invention is implemented, when the fastening mechanism 3 contracts, the rubber layer surface of each pressing plate 301 is on the same circumference.

[0035] Working principle: When the cylinder is in the initial unused state, the push rod 201 is inside the base 1, the connecting block 202 is close to the left side of the base 1, the traction rod 302 is in an inclined state, and the distance between the clamping plate 301 and the curved surface of the base 1 is the smallest. At this time, the fastening mechanism 3 is in a contracted state. When the cylinder is pushed to the left, the push rod 201 will push the connecting block 202 to move to the left, and the traction rod 302 will gradually become parallel to the left side of the base 1; when the traction rod 302 and the left side of the base 1 are parallel to each other, the distance between the clamping plate 301 and the curved surface of the base 1 is the largest. This process is the process of the fastening mechanism 3 expanding outward.

[0036] When the utility model is used, the right side of the base 1 is fixed on the rotating device of the cutting platform, and the cylinder is connected to the central controller. When the cylinder is not in use, the fastening mechanism 3 is inserted into the inner wall of the paper tube, and the cylinder is adjusted to expand the fastening mechanism 3 outward until each pressing plate 301 is tightly attached to the inner wall of the paper tube, and the cylinder movement is stopped. At this time, the pressing plate 301 clamps the paper tube from the inner wall of the paper tube.

[0037] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
