Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard production technology, specifically to a pre-pressing line structure for a corrugated cardboard production line. Background Technology

[0002] In the corrugated cardboard manufacturing industry, the slitting press is an indispensable core unit on the production line, and its performance and functions directly affect the forming quality and production efficiency of the corrugated cardboard. Slitting presses typically need to perform multiple functions, such as point flattening, point concave pressing, and pre-pressing. However, in existing slitting press technologies, achieving these three functions often requires three independent components, each performing its respective function. This design results in an extremely complex overall structure for the slitting press, significantly increasing the difficulty of installation, debugging, and maintenance of the components. This not only consumes substantial manpower and time costs but also easily leads to malfunctions due to component compatibility issues, reducing the reliability and stability of the equipment. Simultaneously, the configuration of three independent components significantly increases the manufacturing cost of the equipment, including the procurement cost of the components themselves, equipment assembly costs, and energy consumption costs during subsequent operation. This greatly limits the economic benefits and market competitiveness of corrugated cardboard manufacturers and hinders the promotion and optimization of slitting press equipment within the industry.

[0019] The present invention will be further described in conjunction with the following embodiments.

[0020] Depend on Figures 1 to 4 As can be seen, the pre-pressing line structure of the corrugated cardboard production line slitting machine described in this embodiment includes a frame 1; an upper knife holder 2 is provided at the top of the frame 1; a lower knife holder 3 is slidably provided at the bottom of the frame 1 along the Y-axis; the lower knife holder 3 is rotatably provided with a flat pressure roller 31 and a lower knife shaft 32 arranged along the X-axis; the lower knife shaft 32 is provided with a pressing lower knife 33; the lower knife holder 3 is provided with a cardboard guide 34; the flat pressure roller 31 is located between the cardboard guide 34 and the lower knife shaft 32;

[0021] The upper tool holder 2 is provided with an upper tool drive 41, a pre-pressure drive 51, an upper tool swing arm 42, and a pre-pressure swing arm 52; the upper tool drive 41 is hinged to the upper tool holder 2; the output end of the upper tool drive 41 is hinged to one end of the upper tool swing arm 42; the middle part of the upper tool swing arm 42 is rotatably connected to the upper tool holder 2; the other end of the upper tool swing arm 42 is rotatably provided with a pressure line cutter 43; the pre-pressure drive 51 is hinged to the upper tool holder 2; the output end of the pre-pressure drive 51 is hinged to one end of the pre-pressure swing arm 52; the other end of the pre-pressure swing arm 52 is rotatably connected to the upper tool holder 2; the middle part of the pre-pressure swing arm 52 is rotatably provided with a pre-pressure wheel 53.

[0022] Specifically, in the pre-pressing line structure of the corrugated cardboard production line described in this embodiment, when the pressing knife performs the point pressing operation, the lower knife holder 3 is driven to move along the Y-axis direction, so that the pre-pressing roller 53 is aligned with the flat pressing roller 31, and the upper pressing knife 43 is aligned with the lower pressing knife 33. Under the control of the pre-pressing drive component 51, the pre-pressing roller 53 falls on the flat pressing roller 31 to realize the cardboard pre-pressing function. The upper knife drive component 41 drives the upper pressing knife 43 to descend, and cooperates with the lower pressing knife 33 to perform point pressing operation on the cardboard.

[0023] When switching modes to perform point pressing and flattening operations, the pre-pressing roller 53 and the pressure line knife 43 are first driven upward by the pre-pressing drive 51 and the upper knife drive 41, respectively. Then, the lower knife holder 3 is driven to move along the Y-axis, so that the pre-pressing roller 53 is aligned with the paperboard 34 and the pressure line knife 43 is aligned with the flat pressing roller 31. Under the control of the pre-pressing drive 51, the pre-pressing roller 53 falls onto the paperboard 34 to realize the paperboard pre-pressing function. The upper knife drive 41 drives the pressure line knife 43 to descend, and cooperates with the flat pressing roller 31 to perform point pressing and flattening operations on the paperboard.

[0024] The pre-pressing line structure of the corrugated cardboard production line described in this embodiment can be driven to move the lower knife holder 3 along the Y-axis direction, so that the upper knife 43 of the pressing line and the lower knife 33 of the pressing line can be aligned to perform point pressing and concave operation, and the upper knife 43 of the pressing line can be aligned with the flat pressing roller 31 to perform point pressing and flattening operation. Furthermore, the pre-pressing roller 53 can perform pre-pressing treatment during both point pressing and concave operation and point pressing and flattening operation.

[0025] The pre-pressing line structure of the corrugated cardboard production line slitting press described in this embodiment includes an upper blade drive component 41 and a pre-pressing drive component 51, both of which are cylinders, hydraulic cylinders, or electric push rods. This configuration facilitates the upward or downward swinging of the upper blade 43 and the pre-pressing roller 53.

The upper blade holder 2 is equipped with an adjusting block 21; the adjusting block 21 has a through-hole 22; the adjusting hole 22 has an adjusting bolt; the adjusting bolt passes through the adjusting hole 22 and abuts against the pre-pressing swing arm 52. The adjusting bolt is not shown in the figure. Through the above-described configuration, the length of the adjusting bolt extending out of the adjusting hole 22 can be adjusted, thereby facilitating control of its abutment position against the pre-pressing swing arm 52 and changing the lower stop point of the pre-pressing roller 53 to adapt to cardboard of different thicknesses.

[0027] The pre-pressing line structure of the corrugated cardboard production line described in this embodiment includes a guide rail 11 arranged along the Y-axis at the bottom of the frame 1; a guide pulley 35 is provided on the lower knife holder 3; and the guide pulley 35 is slidably mounted on the guide rail 11. This arrangement allows the lower knife holder 3 to slide stably along the Y-axis.

[0028] This embodiment describes a pre-pressing line structure for a corrugated cardboard production line, wherein the bottom of the frame 1 is equipped with a switching drive component 12; the output end of the switching drive component 12 is connected to the lower blade holder 3. In this embodiment, the switching drive component 12 is a cylinder, hydraulic cylinder, or electric push rod. This configuration facilitates driving the lower blade to slide along the Y-axis.

[0029] This embodiment describes a pre-pressing line structure for a corrugated cardboard production line. The top of the frame 1 is equipped with an upper knife slide rail 61 and an upper knife rack 62 arranged along the X-axis. The upper knife holder 2 is equipped with an upper knife slider 63 slidably connected to the upper knife slide rail 61. The upper knife holder 2 is equipped with an upper knife motor 64. The output end of the upper knife motor 64 is equipped with an upper knife gear 65 that meshes with the upper knife rack 62. Specifically, through the above-described configuration, the upper knife motor 64 can be activated, driving the upper knife gear 65 to rotate. This, in conjunction with the upper knife rack 62, causes the upper knife holder 2 to move along the upper knife slide rail 61 in the X-axis direction, thereby changing the position of the pressing blade 43 and the pre-pressing roller 53.

[0030] This embodiment describes a pre-pressing line structure for a corrugated cardboard production line. The lower blade holder 3 is equipped with a lower blade slide rail 71 and a lower blade rack 72 arranged along the X-axis. The lower blade 33 of the pressing line is connected to a movable seat 73.
