Detailed Implementation

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0019] like Figures 1 to 5 As shown, a single-gantry manual crimping machine includes a gantry frame 100, a crimping tray 102 fixedly mounted on the gantry frame 100, and a crimping mechanism 400 above the crimping tray 102 on the gantry frame 100 for crimping cardboard placed on the crimping tray 102. The crimping mechanism 400 includes two sets of lifting components mounted opposite each other on the gantry frame 100 and an adjusting assembly 500 for crimping cardboard at different intervals. A limiting mechanism 300 is slidably mounted on the gantry frame 100 between the crimping tray 102 and the crimping mechanism 400 to prevent the cardboard from shifting during crimping.

[0020] In this embodiment, the lifting component includes a second mounting groove 401 formed on the gantry frame 100. A hydraulic rod 402 is fixedly installed in the second mounting groove 401. The output end of the hydraulic rod 402 is vertically downward and fixedly provided with a sliding plate 403 that slides in cooperation with the inner sidewall of the second mounting groove 401. A sliding groove 404 for the sliding plate 403 to slide is formed on the inner sidewall of the second mounting groove 401 that is far apart from each other. An adjustment component 500 is provided on the sliding groove 404. The adjustment component 500 includes components that are spaced parallel to each other in the sliding groove 404. The device has multiple sets of third mounting slots 501. One set of third mounting slots 501 has a bidirectional screw 502 rotatably passing through it. The bidirectional screw 502 has two sections of threads with opposite directions, and each section of thread is fitted with a threaded block 503. Each set of threaded blocks 503 is fixedly equipped with a wire-contacting pressure head 504. Each other set of third mounting slots 501 is fixedly equipped with a limiting rod 505. The threaded block 503 is slidably fitted on the limiting rod 505. One end of the bidirectional screw 502 that passes through the third mounting slot 501 is fixedly equipped with a throttle handle 506.

[0021] Start the hydraulic rod 402. The output end of the hydraulic rod 402 extends vertically downward, driving the sliding plate 403, which is fixedly connected to it, to slide downward along the slide groove 404 in the second mounting groove 401. Since the sliding plate 403 is connected to the adjusting component 500 and the crimping mechanism 400, the downward movement of the sliding plate 403 drives the entire adjusting component 500 to descend synchronously in the vertical direction until the crimping head 504 contacts the cardboard placed on the crimping support plate 102, and the crimping operation begins. By rotating the handle 506, the bidirectional screw 502 is driven to rotate. As the bidirectional screw 502 rotates, the two threaded blocks 503 will move in opposite directions along the axial direction of the bidirectional screw 502. At the same time, the threaded blocks 503 are slidably sleeved on the limiting rods 505 fixedly installed in each of the other three mounting grooves 501. The limiting rods 505 play a guiding role, ensuring that the threaded blocks 503 can only move along the axial direction and will not rotate. As the threaded block 503 moves, the spacing between the wire-contacting pressure heads 504 fixed on each set of threaded blocks 503 also changes accordingly until the required wire-contacting spacing is achieved.

[0022] In this embodiment, the limiting mechanism 300 includes multiple sets of first mounting grooves 301 that are spaced apart and parallel to each other on the inner sidewalls of the gantry frame 100. Each set of first mounting grooves 301 is fixedly provided with a spring column 302. The movable end of the spring column 302 is vertically downward and fixedly provided with a mounting plate 303. The bottom surface of the mounting plate 303 is provided with multiple sets of pressure rollers 304 whose surfaces abut against the surface of the cardboard.

[0023] Based on the thickness of the cardboard to be crimped, the limiting mechanism 300 is initially adjusted. Observe the multiple sets of first mounting slots 301 on the gantry 100, which are spaced apart from each other on the inner sidewall. Each set of first mounting slots 301 has a fixed spring column 302, with the movable end of the spring column 302 pointing vertically downwards and fixedly fitted with a mounting plate 303. The cardboard is placed on the crimping support plate 102. After placement, due to the cardboard's thickness, its upper surface will contact the mounting plate 303. As the crimping mechanism 400 descends, the cardboard is subjected to pressure, and the mounting plate 303, under the action of the cardboard, presses upwards against the movable end of the spring column 302. The spring column 302 automatically compresses or extends according to the cardboard's thickness, ensuring that the mounting plate 303 always fits tightly against the upper surface of the cardboard, limiting its movement. During the crimping process, the mounting plate 303 continuously maintains its limiting effect on the cardboard, preventing it from shifting due to the crimping pressure. The limiting mechanism 300, through the elastic adaptive function of the spring column 302, can automatically adapt to cardboard of different thicknesses. Whether the cardboard is thin or thick, the spring column 302 can adjust the position of the mounting plate 303 according to the cardboard thickness, ensuring effective limiting of the cardboard and improving the equipment's versatility and adaptability to various cardboard thicknesses. Utilizing the rotational characteristics of the pressure roller 304, the sliding friction between the mounting plate 303 and the cardboard is transformed into rolling friction. During the crimping process, this significantly reduces friction on the cardboard surface, effectively preventing scratches and wear caused by excessive friction, improving the finished cardboard quality, and reducing the scrap rate. Multiple sets of parallel pressure rollers 304 provide a more uniform limiting force in the width direction of the cardboard. Even if the cardboard is subjected to uneven pressure during crimping, the pressure roller 304 can flexibly adjust its contact state with the cardboard through its own rotation, continuously and stably limiting the cardboard and preventing deviation, further ensuring the accuracy of the crimping.

[0024] In this embodiment, the crimping plate 102 is provided with a clamping mechanism 200 capable of clamping cardboard of different widths. The clamping mechanism 200 includes two sets of spaced and adjustable mounting blocks 202 mounted on the crimping plate 102 via a drive member 201. Each set of mounting blocks 202 is fixedly provided with a stop 203. The stop 203 is provided with a limiting groove 204 for limiting the left and right sides of the cardboard. Multiple sets of drive rollers 205 that rotatably contact the sides of the cardboard are provided in the limiting groove 204.

[0025] Place the cardboard on the crimping plate 102, aligning the two edges of the cardboard with the limiting grooves 204 on the retainers 203. As the mounting block 202 continues to move, the retainers 203 gradually approach the cardboard until the drive roller 205 within the limiting grooves 204 contacts the side of the cardboard. When the drive roller 205 contacts the cardboard, it rotates and rolls as the cardboard's position adjusts, until the cardboard is securely clamped between the two retainers 203, completing the clamping and fixing of the cardboard. The distance between the two sets of mounting blocks 202 and retainers 203 can be precisely adjusted via the drive component 201, achieving accurate fit for both narrow and large cardboard sizes.

[0026] In this embodiment, the bottom surface of the gantry frame 100 is fixedly provided with multiple sets of self-locking casters 101 at intervals.

[0027] The self-locking casters 101 enable the movement and fixation of the equipment, greatly reducing the labor intensity of operators, improving work efficiency, and also reducing the risk of personnel injury that may occur when moving equipment.

[0028] Working process and principle: When using this device, according to the width of the cardboard to be contacted, the drive unit 201 on the contact plate 102 is activated. The drive unit 201 drives the two sets of mounting blocks 202 to move, and the spacing of the mounting blocks 202 is adjusted so that the spacing of the upper limit groove 204 of the stop frame 203 is adapted to the width of the cardboard. The cardboard is placed on the contact plate 102, so that the two sides of the cardboard are aligned with the limit groove 204. As the mounting blocks 202 continue to move, the stop frame 203 approaches the cardboard, and the drive roller 205 in the limit groove 204 contacts the side of the cardboard, completing the clamping and fixing of the cardboard in the width direction. Observe the thickness of the cardboard. The spring column 302 in the first mounting groove 301 on the inner side wall of the gantry frame 100 and the mounting plate 303 fixed at its movable end will automatically adjust the position according to the thickness of the cardboard. The pressure roller 304 on the bottom surface of the mounting plate 303 abuts against the upper surface of the cardboard, limiting the cardboard in the thickness direction to prevent it from shifting when touching the line. According to the required line-touching distance, the operator rotates the handle 506 at one end of the bidirectional screw 502, causing the bidirectional screw 502 to rotate. Because its two ends have opposite screw directions, the threaded block 503 fitted on it moves in opposite axial directions, causing the line-touching pressure head 504 fixed on the threaded block 503 to adjust the distance. The threaded block 503 moves smoothly under the guidance of the limiting rod 505 until the line-touching pressure head 504 reaches the required distance. Then, the hydraulic rod 402 is activated, and its output end extends vertically downwards, causing the sliding plate 403 fixed at its output end to slide downwards along the groove 404 within the second mounting groove 401. The sliding plate 403 drives the adjusting component 500 and the creasing mechanism 400 to descend as a whole. The creasing head 504 gradually approaches and contacts the paperboard to perform the creasing operation. During the creasing process, the pressure roller 304 rolls on the surface of the paperboard to reduce friction and ensure the stability of the paperboard. The drive roller 205 also rolls to maintain the stability of the paperboard in the width direction and ensure the accuracy of the creasing.

Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones.
