Description

Technical Field

[0001] This utility model relates to the field of corrugated cardboard processing technology, specifically to a corrugated cardboard slitting spacing adjustment structure. Background Technology

[0002] Corrugated board slitting is a key process in carton production, mainly used to slit and crimp large-format corrugated board according to product specifications.

[0003] According to CN219819853U, a high-efficiency and fast-adjustable automatic corrugated cardboard slitting mechanism is disclosed. This technology discloses a technical solution including "a machine body and a slitting blade, wherein a slitting assembly is provided inside the machine body; the slitting assembly includes a rotary motor fixedly installed on the right side of the machine body, and threaded holes are opened on the outer surfaces of the slitting blade, the first rotating shaft, and the second rotating shaft, respectively. Fastening bolts are threaded into the internal threads of the threaded holes, and nuts are threaded onto the outer surfaces of the fastening bolts." It has the technical effect that "by setting up a slitting assembly, multiple slitting blades can be installed to quickly slit the corrugated cardboard, thereby improving the cutting efficiency. When it is necessary to adjust the cutting width of the corrugated cardboard, only the cooperation of the fastening bolts and nuts is needed to remove a portion of the slitting blades from the outer surfaces of the first rotating shaft and the second rotating shaft, thereby achieving the effect of quickly adjusting the cutting width of the corrugated cardboard."

[0004] The cutting tools in the above scheme are fixed by fastening bolts and nuts. When adjusting the cutting width, it is necessary to manually disassemble and reinstall some of the dividing blades. This fixing method requires manual operation one by one when adjusting the spacing between multiple blades, which seriously affects production efficiency and the convenience of equipment use. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a corrugated cardboard slitting spacing adjustment structure. Through linkage, it achieves synchronous spacing adjustment of multiple sets of blades, while maintaining precise alignment of the upper and lower blades and independently controlling the cutting pressure, thereby improving production efficiency and processing adaptability.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a corrugated cardboard slitting spacing adjustment structure, comprising a slitting mechanism for slitting corrugated cardboard, the slitting mechanism comprising:

[0007] The main components include uprights symmetrically arranged on the left and right sides. A movable seat is longitudinally slidably installed at the upper end of the uprights. An upper shaft is rotatably installed between the movable seats on the left and right sides. A fixed seat is fixed at the lower end of the uprights. A lower shaft is rotatably installed between the fixed seats on the left and right sides.

[0008] The adjustment assembly includes a horizontal plate fixed between the upper ends of the left and right uprights, a first guide rail fixed at both the left and right ends of the top of the horizontal plate, a first slider slidably mounted on the first guide rail, a guide plate fixed between the tops of the first sliders at the left and right ends, and several guide grooves opened on both the left and right sides inside the guide plate.

[0009] The cutting assembly includes several upper sliding sleeves that are slidably mounted on an upper shaft. A slide frame is fixed to the upper end of each upper sliding sleeve, and a cam is rotatably mounted on the top of the slide frame, with the cam located inside a corresponding guide groove.

[0010] Preferably, the cutting assembly includes a lower shaft lug fixed to the lower end of the upper sliding sleeve, an upper blade rotatably mounted on the right end of the lower shaft lug, a plurality of lower sliding sleeves slidably mounted on the lower shaft rod, a lower blade rotatably mounted on the right end of the lower sliding sleeve and cooperating with the upper blade, an upper shaft lug fixed to the upper end of the lower sliding sleeve, a limit groove hole opened inside the upper shaft lug, a limit rod fixed to the left end of the lower shaft lug, and the limit rod is located inside the limit groove hole.

[0011] Preferably, the main component further includes a first cylinder mounted on the upper end of the stand, and the output end of the first cylinder is fixed to the movable seat.

[0012] Preferably, the adjustment assembly further includes an extension plate fixed to the rear end of the horizontal plate, with a second cylinder mounted on the upper end of the extension plate, and the output end of the second cylinder fixed to the guide plate.

[0013] Preferably, the adjustment assembly further includes a second guide rail fixed to the top of the cross plate, and second sliders are fixed to both ends of the carriage, with the second sliders slidably mounted on the second guide rail.

[0014] Preferably, the guide grooves on the left side and the guide grooves on the right side of the guide plate are arranged symmetrically.

[0015] Beneficial effects

[0016] This utility model provides a structure for adjusting the slitting spacing of corrugated cardboard. Compared with the prior art, it has the following advantages:

[0017] 1. Driven by the second cylinder, the guide plate moves along the first guide rail in cooperation with the first slider, forcing the cams in the guide grooves inside to move relative to each other. Since the cams are rotatably mounted on the top of the carriage, and the carriage is fixedly connected to the upper sliding sleeve, the movement of the cams under the constraint of the guide grooves will be converted into the lateral sliding of the carriage and the upper sliding sleeve along the upper shaft, thereby realizing the synchronous linkage adjustment of the spacing between multiple cutting components. The overall structure is not only easy to operate and reliable to adjust, but also effectively reduces the complexity and time cost of adjusting multiple blade positions one by one, greatly improving the production flexibility and efficiency of corrugated cardboard slitting.

[0018] 2. When the upper sliding sleeve moves laterally along the upper shaft, it drives the upper cutter to move left and right through the lower shaft lug. At the same time, the limiting rod fixed to the lower shaft lug drives the lower cutter on the lower sliding sleeve to move synchronously through the upper shaft lug, so that the lower cutter and the upper cutter always remain vertically aligned. Furthermore, when the upper cutter adjusts the distance between itself and the lower cutter, the lower shaft lug drives the limiting rod to move longitudinally inside the limiting slot. Since the limiting slot is a vertical longitudinal slot, its structure allows the limiting rod to move freely in the vertical direction without exerting a longitudinal force on the lower sliding sleeve. This ensures that the lifting action of the upper cutter is not transmitted to the lower sliding sleeve and the lower cutter, and ensures that the lower cutter is always stably at the preset working height.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 - Figure 4This utility model provides a technical solution: a corrugated cardboard slitting spacing adjustment structure, including a slitting mechanism 1 for slitting corrugated cardboard, the slitting mechanism 1 including:

[0026] The main component 11 includes uprights 111 symmetrically arranged on the left and right sides. A movable seat 112 is longitudinally slidably installed at the upper end of the upright 111. An upper shaft 113 is rotatably installed between the movable seats 112 on the left and right sides. A fixed seat 114 is fixed at the lower end of the upright 111. A lower shaft 115 is rotatably installed between the fixed seats 114 on the left and right sides.

[0027] The adjustment assembly 12 includes a horizontal plate 121 fixed between the upper ends of the left and right uprights 111. The top left and right ends of the horizontal plate 121 are fixed with first guide rails 122. The first sliders 123 are slidably installed on the first guide rails 122. The top ends of the first sliders 123 at the left and right ends are fixed with guide plates 124. The guide plates 124 have several guide grooves 125 on the left and right sides inside.

[0028] The cutting assembly 13 includes several upper sliding sleeves 131 that are slidably mounted on the upper shaft 113. A slide 132 is fixed to the upper end of the upper sliding sleeve 131. A cam 133 is rotatably mounted on the top of the slide 132, and the cam 133 is located inside the corresponding guide groove 125.

[0029] In this embodiment, the guide plate 124 is driven by the second cylinder 127 to move along the first guide rail 122 in cooperation with the first slider 123, which forces the cams 133 located in the guide grooves 125 inside to move relative to each other. Since the cams 133 are rotatably mounted on the top of the slide 132, and the slide 132 is fixedly connected to the upper slide sleeve 131, the movement of the cams 133 under the constraint of the guide grooves 125 will be converted into the lateral sliding of the slide 132 and the upper slide sleeve 131 along the upper shaft 113, thereby realizing the synchronous linkage adjustment of the spacing of multiple cutting components 13. The overall structure is not only easy to operate and reliable to adjust, but also effectively reduces the complexity and time cost of adjusting multiple blade positions one by one, and greatly improves the production flexibility and efficiency of corrugated cardboard slitting.

[0030] Specifically, the cutting assembly 13 includes a lower shaft lug 134 fixed to the lower end of the upper sliding sleeve 131. An upper blade 135 is rotatably mounted on the right end of the lower shaft lug 134. Several lower sliding sleeves 136 are slidably mounted on the lower shaft rod 115. A lower blade 137 is rotatably mounted on the right end of the lower sliding sleeve 136 and cooperates with the upper blade 135. An upper shaft lug 138 is fixed to the upper end of the lower sliding sleeve 136. A limiting slot 139 is opened inside the upper shaft lug 138. A limiting rod 1310 is fixed to the left end of the lower shaft lug 134, and the limiting rod 1310 is located inside the limiting slot 139.

[0031] In this embodiment, when the upper sliding sleeve 131 moves laterally along the upper shaft 113, the upper blade 135 moves left and right through the lower shaft lug 134. At the same time, the limiting rod 1310 fixed to the lower shaft lug 134 drives the lower blade 137 on the lower sliding sleeve 136 to move synchronously through the upper shaft lug 138, so that the lower blade 137 and the upper blade 135 always remain vertically aligned. Furthermore, when the upper blade 135 adjusts the distance between itself and the lower blade 137, the lower shaft lug 134 drives the limiting rod 1310 to move longitudinally inside the limiting slot 139. Since the limiting slot 139 is a vertical slot, its structure allows the limiting rod 1310 to move freely in the vertical direction without exerting a longitudinal force on the lower sliding sleeve 136, thereby ensuring that the lifting action of the upper blade 135 is not transmitted to the lower sliding sleeve 136 and the lower blade 137, and ensuring that the lower blade 137 is always stably at the preset working height.

[0032] Specifically, the main component 11 also includes a first cylinder 116 installed on the upper end of the stand 111, and the output end of the first cylinder 116 is fixed to the movable seat 112.

[0033] In this embodiment, when the first cylinder 116 is activated, its output end directly drives the movable seat 112 to slide longitudinally along the upright frame 111, thereby driving the entire upper shaft 113 and all the upper sliding sleeves 131 and upper blades 135 mounted on it to rise and fall synchronously. By controlling the stroke of the first cylinder 116, the vertical distance between the upper blade 135 and the lower blade 137 can be precisely adjusted. The overall lifting and adjustment method can adapt to the cutting pressure requirements of corrugated cardboard of different thicknesses, ensuring that the distance between all upper blades 135 and the corresponding lower blades 137 remains consistent, thus avoiding cutting quality problems caused by uneven local pressure.

[0034] Specifically, the adjustment assembly 12 also includes an extension plate 126 fixed to the rear end of the horizontal plate 121. A second cylinder 127 is installed on the upper end of the extension plate 126, and the output end of the second cylinder 127 is fixed to the guide plate 124.

[0035] In this embodiment, the pneumatic drive not only improves the speed and efficiency of tool spacing adjustment and enables rapid switching between different specifications of cardboard during production, but also ensures the consistency and accuracy of all tool spacing adjustments through precise stroke control of the cylinder.

[0036] Specifically, the adjustment assembly 12 also includes a second guide rail 128 fixed to the top of the horizontal plate 121, and a second slider 129 fixed to both ends of the slide 132, and the second slider 129 is slidably mounted on the second guide rail 128.

[0037] In this embodiment, when the guide plate 124 drives the slide 132 to move laterally via the cam 133, the second slider 129 slides along the second guide rail 128, providing stable linear motion constraints and rigid support for the slide 132, effectively eliminating radial clearance and deflection torque during the movement process.

[0038] Specifically, the guide grooves 125 on the left side and the guide grooves 125 on the right side of the guide plate 124 are arranged symmetrically.

[0039] In this embodiment, the tilt angle of each guide groove 125 is set differently according to the initial position of its corresponding cutting component 13, so as to ensure that all cutting components 13 can achieve precise synchronous equidistant displacement when the guide plate 124 moves laterally.

[0040] The working principle and usage process of this utility model are as follows: First, the operator starts the second cylinder 127 through the control system. Its output end drives the guide plate 124 to move laterally along the first guide rail 122 via the first slider 123. The guide grooves 125, symmetrically arranged with varying inclination angles inside the guide plate 124, then push the corresponding cam 133 to produce precise displacement. The cam 133 drives the upper sliding sleeve 131 to slide laterally along the upper shaft 113 via the slide 132. During this process, the second sliders 129 at both ends of the slide 132 slide along the second guide rail 128, ensuring smooth and deflection-free movement. Simultaneously, the fixed... The limiting rod 1310 of the lower shaft lug 134 drives the lower sliding sleeve 136 and the lower blade 137 to move synchronously along the lower shaft rod 115 through the upper shaft lug 138, so that the upper and lower blades always remain aligned. When it is necessary to adjust the cutting pressure, the first cylinder 116 drives the movable seat 112 to raise and lower the upper shaft rod 113 as a whole. At this time, the limiting rod 1310 moves freely longitudinally in the limiting slot 139 to ensure that the lower blade 137 maintains a fixed working height. The entire mechanism realizes the synchronous equidistant adjustment and pressure control of multiple cutting components 13 through the cooperation of pneumatic drive and mechanical linkage, perfectly adapting to the slitting and processing needs of corrugated cardboard of different specifications.
