[0024] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0025] Reference Figure 1-5 As shown, a guide device for a filling machine cutter 6 includes a cutter 6, a cutter seat 1, a power component and a guide assembly, wherein the cutter seat 1 is provided with a cutter groove 7 penetrating the cutter seat 1, the guide assembly is connected to the cutter 6, the cutter 6 is slidably arranged on the cutter groove 7, the power component is connected to the cutter 6, and the power component drives the cutter 6 to reciprocate on the cutter groove 7.

[0026] The present invention solves many defects and shortcomings of the existing filling machine cutter 6 device by arranging a guide component on the cutter 6 without increasing the manufacturing difficulty, manufacturing cost and use cost.

[0027] The present invention provides a guide assembly on the cutter 6, which can play a supporting and guiding role when cutting packaging materials. When the cutter 6 cuts the packaging materials, it will not rub against the cutter groove 7, and will not be deformed or bent, thereby effectively extending the service life of the cutter 6 and the cutter seat 1. At the same time, the guide assembly is installed on the cutter 6. The parts of the guide assembly are easy to replace and have good adaptability, thereby ensuring that the cutter 6 is flexible in extension and contraction during use, thereby ensuring the stable operation of the filling machine.

[0028] The guide assembly includes a guide block 3 , which is arranged on the cutter body of the cutter 6 . The cutter seat 1 is provided with a guide block hole 12 matching the guide block 3 , and the guide block 3 is slidably arranged in the guide block hole 12 .

[0029] The cross-sectional shape of the guide block hole 12 is any one of a semicircle, a rectangle, a trapezoid and a triangle, and the cross-sectional shape of the guide block 3 is the same as the cross-sectional shape of the guide block hole 12 .

[0030] The guide block 3 is made of soft wear-resistant material, and the hardness of the guide block 3 is lower than the hardness of the cutter 6 .

[0031] At least one guide block hole 12 is distributed at one end of the cutter seat 1. The cross-sectional shape of the guide block hole 12 is semicircular or circular, but is not limited to semicircular and circular, and can also be other shapes such as rectangular, trapezoidal, triangular, etc. The guide block 3 is made of soft wear-resistant material, which can be any one of aluminum, copper, and plastic, and has a hardness much lower than that of the cutter 6, which can effectively slow down the wear of the cutter 6, increase the service life of the cutter 6, and ensure the stability of the cutter 6.

[0032] The power component includes a bracket 11 and a cutter push rod 10. The bracket 11 is fixedly connected to the cutter seat 1. The cutter push rod 10 is slidably supported in a guide hole 9 of the bracket 11. The cutter push rod 10 passes through the guide hole 9 and is drivingly connected to the cutter 6.

[0033] The bracket 11 is the basis for installing the entire cutter 6 guide device. The cutter seat 1 is fixed on the bracket 11. The cutter push rod 10 passes through the guide hole 9 and is connected to the cutter 6. The cutter push rod 10 drives the cutter 6 to achieve rapid cutting action.

[0034] The cutter push rod 10 is connected to a driver for providing power. The driver can provide power for a hydraulic device, a pneumatic device, a servo motor (providing reciprocating motion by driving a screw rod, a cam, etc.), etc.

[0035] The bracket 11 is provided with a recessed portion, and a limiting groove for limiting the axial movement of the guide assembly is formed between the recessed portion of the bracket 11 and the cutter seat 1 , and the limiting groove prevents the guide assembly from being detached from the cutter seat 1 .

[0036] The guide block 3 is floatingly supported in the guide block hole 12 and can move flexibly in the guide block hole 12. The end surface of the guide block hole 12 and the end surface (recess) of the bracket 11 in contact with the guide block 3 define the axial position of the guide block 3, effectively preventing it from falling out during use.

[0037] The height of the cutting groove 7 is greater than the thickness of the cutting knife 6 , and the height of the working surface 13 of the guide block 3 is greater than the height of the inner surface 8 of the cutting groove 7 . The cutting knife 6 is clamped by the working surface 13 of the guide block 3 to be maintained in the middle position of the cutting groove 7 .

[0038] The cutter 6 is a cutting tool with a certain edge shape. The blade end of the cutter 6 is inserted into the cutter groove 7 and is clamped by the working surface 13 of the guide block 3 to be maintained in the middle position of the cutter groove 7, and can be flexibly moved in the cutter groove 7 along the movement direction A of the cutter 6.

[0039] The cutter 6 is provided with a positioning hole, and one end of the cutter push rod 10 is provided with a positioning block matching the positioning hole, and the positioning block is penetrated through the positioning hole.

[0040] A limit block is provided on the free end of the cutter push rod 10, and the limit block is connected to the cutter push rod 10. The limit block is slidably arranged in the guide hole 9. The cutter push rod 10 is slidably supported in the guide hole 9 of the bracket 11 through the limit block, and can be flexibly moved in the guide hole 9 along the movement direction A of the cutter 6.

[0041] The utility model further comprises an anvil board 2, which is arranged opposite to the cutting knife seat 1, and the anvil board 2 is provided with a groove 4 matching with the cutting knife 6.

[0042] By providing a guide assembly on the cutter 6, when the cutter 6 cuts the packaging material, it will not deviate and cut the edge of the groove 4 on the heater, thus avoiding abnormal damage to the cutter 6 and the heater.

[0043] The packaging material 5 is a paper-based composite material packaging material 5, which is tightly clamped between the cutter seat 1 and the chopping board 2 in a known manner. The chopping board 2 and the cutter seat 1 press the packaging material 5 to facilitate cutting. A groove 4 is provided on the chopping board 2 to accommodate the blade of the cutter 6 when the cutter 6 cuts the packaging material 5. The chopping board 2 can also be a heater. When pressing the packaging material 5 with the cutter seat 1, the packaging material 5 is heated, and the sealing of the packaging material 5 can be completed at the same time.

[0044] Usage Process

[0045] The packaging material 5 is tightly pressed by the cutter seat 1 and the cutting board 2, and the cutting board 2 heats the packaging material 5 and seals it. When the driver provides power, the cutter push rod 10 pushes the cutter 6 to the left along the movement direction A of the cutter 6 under the support and guidance of the guide block 3, and extends out of the cutter groove 7 in the cutter seat 1 to cut the packaging material 5. The blade of the cutter 6 enters the groove 4 to cut the packaging material 5. Then, the cutter push rod 10 drives the cutter 6 to return to the cutter seat 1 to the right along the movement direction A of the cutter 6 under the support and guidance of the guide block 3, completing the cutting action of the packaging material 5.

[0046] During the entire cutting and resetting process, the guide block 3 always supports and guides the cutter 6, so that the cutter 6 will not be offset, cut off-center, bend, rub against the cutter groove 77, or the blade will not hit the groove 45, etc., which can simply and effectively realize the guidance of the cutter 6 of the paper-based composite material packaging and filling machine.

[0047] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
