[0038] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0039] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0040] Reference Figures 1-8 As shown, a cardboard box slotting device includes: a placement platform 100 for placing cardboard, a mounting frame 101 fixedly mounted on the placement platform 100, and two sets of adjustable-spaced slotting blades 102 mounted on the mounting frame 101 via a slotting mechanism 200. The slotting blades 102 have a rhomboid cross-section.

[0041] The grooving mechanism 200 includes: a grooving component for driving the grooving blade 102 to rotate and grooving the cardboard, and an adjusting component for adjusting the distance between the two sets of grooving blades 102. The mounting frame 101 is also provided with an adjusting mechanism 300 for adjusting the grooving length and grooving width of the grooving blade 102.

[0042] In use, place the cardboard to be slotted on the placement platform 100, ensuring the cardboard is stable and stationary. Using the adjusting mechanism in the slotting mechanism 200, adjust the distance between the two sets of slotting blades 102 according to the width of the cardboard and the required slotting position. Adjust the slotting length and width of the slotting blades 102 using the adjusting mechanism 300 on the mounting frame 101 to meet specific slotting requirements. Activate the slotting component in the slotting mechanism 200 to start rotating the slotting blades 102. The diamond-shaped cross-section of the slotting blades 102 allows the slotting width to be controlled by driving the lifting and lowering of the slotting blades 102. By adjusting the distance between the two sets of slotting blades 102, this device can adapt to cardboard of different widths, improving the versatility of the equipment.

[0043] Reference Figure 1 and Figure 7 As shown, the adjusting mechanism 300 includes: a reciprocating lead screw 302, a mounting block 304, and a hydraulic rod 306; wherein,

[0044] The mounting bracket 101 has a sliding groove 301, and a reciprocating screw 302 is rotatably mounted in the sliding groove 301. A rotary motor 303 with its output end fixedly connected to the reciprocating screw 302 is fixedly mounted on the mounting bracket 101. A mounting block 304 that slides in cooperation with the sliding groove 301 is threaded onto the reciprocating screw 302. Multiple sets of hydraulic rods 306 are fixedly mounted on the mounting block 304. The output shaft of the hydraulic rod 306 is vertically downward and a grooving mechanism 200 is fixedly mounted at its top.

[0045] When using this device, the rotary motor 303 is started, and its output end drives the reciprocating screw 302 to rotate within the sliding groove 301. Since the mounting block 304 is threaded onto the reciprocating screw 302 and slides within the sliding groove 301, the rotation of the rotary motor 303 causes the mounting block 304 to reciprocate within the sliding groove 301. The position of the mounting block 304 is adjusted according to the width of the carton and the slotting requirements, thereby determining the lateral position of the slotting mechanism 200. Once the position of the mounting block 304 is determined, the hydraulic rod 306 is started, and its output shaft moves vertically downwards, causing the slotting mechanism 200 to descend. The extension of the hydraulic rod 306 is adjusted according to the thickness of the carton and the required slotting depth. After the position and depth of the slotting mechanism 200 are adjusted, the drive mechanism in the slotting mechanism 200 is started, causing the slotting blade 102 to rotate. The carton is placed on the placement table 100, and the carton is pushed through the slotting blade 102 to complete the slotting operation.

[0046] Reference Figure 7 As shown, the mounting bracket 101 is fixedly provided with multiple sets of limiting strips 305 arranged parallel to the sliding groove 301, and the mounting block 304 is provided with a limiting groove 307 that slides with the limiting strips 305.

[0047] In the above scheme, the cooperation between the limiting strip 305 and the limiting groove 307 makes the mounting block 304 more stable during movement, reducing shaking and deviation.

[0048] Reference Figure 1 and Figure 8 As shown, the slotted component includes: a first motor 202, a rotating shaft 203, and a key block 211; wherein,

[0049] The output end of the hydraulic rod 306 is fixedly provided with a bracket 201. A rotating shaft 203 is rotatably provided inside the bracket 201. Multiple sets of keyways 204 are opened on the rotating shaft 203 along its circumference. The grooving cutter 102 is sleeved on the rotating shaft 203 and a key block 211 that cooperates with the keyway 204 is fixed on its inner side wall. A first motor 202 with a horizontally arranged output shaft and its top end fixedly connected to the rotating shaft 203 is fixedly provided on the bracket 201.

[0050] When in use, the first motor 202 is started, and its output shaft drives the rotating shaft 203 to rotate inside the bracket 201. Since the grooving knife 102 is fixedly connected to the keyway 204 of the rotating shaft 203 through the key block 211, the rotation of the rotating shaft 203 will drive the grooving knife 102 to rotate together, placing the cardboard on the placement table 100 and allowing it to pass through the rotating grooving knife 102 to complete the grooving operation of the carton.

[0051] Reference Figure 4 and Figure 7As shown, the adjusting component includes: a bidirectional screw 205, a threaded sleeve 207, a connecting rod 208, and a rotating drum 209; wherein,

[0052] The bracket 201 is also rotatably provided with a bidirectional screw 205 parallel to the rotating shaft 203. The bidirectional screw 205 has two sections of threads with opposite directions, and each section of thread is threaded with a threaded sleeve 207. The threaded sleeve 207 is rotatably fitted with a connecting rod 208 through a bearing. The side wall of the grooving cutter 102 is coaxially rotatably provided with a rotating drum 209 through a bearing 210. One end of the connecting rod 208 is fixedly fitted onto the rotating drum 209. The bracket 201 is fixedly provided with a second motor 206 with the output shaft horizontally set and the top end fixedly connected to the bidirectional screw 205.

[0053] In the above scheme, the second motor 206 is started, and its output shaft drives the bidirectional screw 205 to rotate on the bracket 201. Since the bidirectional screw 205 has two sections of threads with opposite directions, when the bidirectional screw 205 rotates, the two threaded sleeves 207 will move in opposite directions respectively. The threaded sleeves 207 drive the rotating drum 209 and the grooving knife 102 to move together through the connecting rod 208, thereby adjusting the distance between the two sets of grooving knives 102. Through the cooperation of the bidirectional screw 205 and the threaded sleeves 207, the distance between the two sets of grooving knives 102 can be precisely adjusted to meet the grooving requirements of different carton widths.

[0054] Reference Figures 1-2 As shown, the slotting device further includes: a limiting mechanism 400 slidably disposed on the placement table 100 for limiting the cardboard; wherein,

[0055] The limiting mechanism 400 includes two sets of limiting members arranged opposite each other with adjustable spacing, each set of limiting members being provided with clamping members for clamping the upper and lower surfaces of the cardboard.

[0056] In the above solution, the spacing between the two sets of limiting components is adjusted according to the width of the cardboard to ensure that the cardboard is firmly clamped in the left-right direction. The clamping components are activated to hold the upper and lower surfaces of the cardboard, ensuring that the cardboard will not move or deform during the grooving process. By using the limiting mechanism 400 to firmly clamp and limit the cardboard, the movement and deformation of the cardboard during the grooving process are reduced, and the grooving accuracy is improved.

[0057] Reference Figures 2-4 As shown, the limiting component includes: a sliding mounting block 401, a limiting plate 402, and a driving component; wherein,

[0058] The placement platform 100 has multiple sets of guide grooves 408 spaced apart. The placement platform 100 is provided with a sliding mounting block 401 that slides with the guide grooves 408. The sliding mounting block 401 is fixed with a limiting plate 402 that limits the left and right movement of the cardboard. The placement platform 100 is provided with a driving component that drives the sliding mounting block 401 to slide.

[0059] In the above scheme, the cardboard to be slotted is placed on the placement table 100, ensuring that one end of the cardboard is aligned with the initial position of the limiting plate 402. According to the width of the cardboard, the sliding mounting block 401 is driven to slide in the guide groove 408 by the driving component, thereby adjusting the position of the limiting plate 402. After the position of the limiting plate 402 is adjusted, the slotting mechanism 200 is started, so that the slotting knife 102 performs the slotting operation on the cardboard.

[0060] Reference Figure 6 As shown, the driving component includes: a drive motor 407, a gear 409, and a rack 410; wherein,

[0061] The placement platform 100 is fixedly provided with an output shaft that is vertically upward and a gear 409 is fixedly sleeved at its top. The side of the sliding mounting block 401 is fixedly provided with a rack 410 that meshes with the gear 409.

[0062] In the above scheme, the drive motor 407 is started, and its output shaft drives the gear 409 to rotate. The rotating gear 409 meshes with the rack 410 fixed to the side of the sliding mounting block 401, causing the sliding mounting block 401 to slide within the guide groove 408. The sliding of the sliding mounting block 401 causes the limiting plate 402 to move, thereby adjusting the distance between the limiting plate 402 and the cardboard, ensuring that the cardboard is securely limited. Through the cooperation of the drive motor 407, gear 409, and rack 410, the position of the limiting plate 402 can be precisely adjusted to meet the needs of cardboard of different widths.

[0063] Reference Figure 6 As shown, the bottom surface of the sliding mounting block 401 is provided with multiple sets of rollers 411 that rotatably contact the inner bottom wall of the placement platform 100.

[0064] In the above scheme, the roller 411 rolls on the inner bottom wall of the placement platform 100, reducing the frictional resistance when the sliding mounting block 401 moves, making the adjustment process smoother. At the same time, the rolling of the roller 411 reduces the direct contact between the sliding mounting block 401 and the placement platform 100, reducing wear and extending service life.

[0065] Reference Figure 5 As shown, the clamping component includes: a slide bar 403, a spring 404, and a pressure plate 405; wherein,

[0066] Multiple sets of parallel and vertically arranged slide rods 403 are slidably arranged on the limiting plate 402 at intervals. The bottom surface of the slide rod 403 is fixedly provided with a pressure plate 405 that contacts the surface of the cardboard. A spring 404 is sleeved on one set of slide rods 403, with its two ends abutting against the side wall of the limiting plate 402 and the side wall of the pressure plate 405 respectively. A limiting block 406 is fixedly provided at the top.

[0067] When in use, place the cardboard between the limiting plate 402 and the pressure plate 405, ensuring that the upper and lower surfaces of the cardboard are in contact with the limiting plate 402 and the pressure plate 405 respectively. After the cardboard is placed, the pressure plate 405 moves downward under the pressure of the cardboard, causing the slide bar 403 to slide on the limiting plate 402. At the same time, the spring 404 is compressed. The elastic force of the spring 404 causes the pressure plate 405 to generate an upward clamping force on the cardboard, which works together with the limiting plate 402 to firmly clamp the cardboard.

[0068] In summary, the cardboard slotting device provided by this utility model allows for the following steps: The cardboard to be slotted is placed on the placement table 100, ensuring correct positioning. Based on the cardboard's dimensions and slotting requirements, the drive motor 407 is activated. The output shaft of the drive motor 407 rotates the gear 409, which meshes with the rack 410, thereby driving the sliding mounting block 401 to slide within the guide groove 408. The position of the limiting plate 402 is adjusted. When the limiting plate 402 reaches the predetermined position, the cardboard is clamped by a clamping mechanism consisting of a slide rod 403, a spring 404, and a pressure plate 405. The spring 404 provides appropriate pressure to ensure the cardboard remains stable during slotting. The position of the slotting blade 102 is adjusted via the adjusting mechanism 300 according to the required slotting length and width. The rotary motor 303 is started, and its output shaft drives the reciprocating screw 302 to rotate, causing the mounting block 304 to slide within the sliding groove 301, thereby adjusting the longitudinal position of the grooving knife 102. The vertical position of the grooving knife 102 is adjusted via the hydraulic rod 306 to ensure an appropriate gap between the grooving knife 102 and the cardboard. The second motor 206 is started, and its output shaft drives the bidirectional screw 205 to rotate. Since the bidirectional screw 205 has two sections of threads with opposite directions, the threaded sleeve 207 will move along the bidirectional screw 205 in opposite directions. The connecting rod 208 and the rotating drum 209 drive the two sets of grooving blades 102 to move closer or further apart, adjusting the distance between the grooving blades 102. The first motor 202 is started, and the output shaft of the first motor 202 drives the rotating shaft 203 to rotate. Since the key block 211 on the inner side wall of the grooving blade 102 cooperates with the keyway 204 on the rotating shaft 203, the grooving blade 102 will rotate with the rotation of the rotating shaft 203. The grooving blade 102 can form the required grooving shape on the cardboard. The cardboard is grooved under the action of the grooving blade 102, and at the same time, the limiting mechanism 400 ensures that the cardboard remains stable during the grooving process.
