Description

Technical Field

[0001] The utility model relates to the technical field of cardboard printing machines, in particular to a cardboard creasing device. Background Art

[0002] Corrugated cardboard is a multi-layer adhesive body, which is composed of at least one layer of corrugated core paper and one layer of cardboard. It has high mechanical strength and can withstand collisions and falls during transportation. Corrugated paper needs to be creased during the production and printing process.

[0003] After searching, the Chinese patent publication number is CN218615745U, which discloses a creasing device for a corrugated cardboard printing machine. Through the arrangement of grooves, creasing strips, through-holes, insertion rods and handles, when it is necessary to creasing the corrugated cardboard, the distance between the indentations on the corrugated cardboard can be adjusted according to the needs of the user. The creasing strip is placed inside the groove, and the handle is held. The handle drives the insertion rod to be inserted into the inside of the iron plate and through the through-hole to fix the creasing strip, which is convenient for creasing the corrugated cardboard. Through the arrangement of magnets, the magnets can be adsorbed on the side walls of the iron plate, and the position of the handle can be limited. The distance between the creasing strips can be adjusted through the above operation, but the operation is more cumbersome, and the equal distance adjustment is more difficult, which is not convenient and quick to use.

[0025] The utility model is further described below in conjunction with the accompanying drawings:

[0027] The sliding installation mechanism 4 includes a sliding seat 401, which is slidably connected in the horizontal sliding groove 301. A longitudinal sliding groove 402 is provided on the side of the sliding seat 401 away from the pressure plate 3. A mounting block 403 is welded at the bottom of the sliding seat 401. The indentation strip 8 is connected between two corresponding mounting blocks 403 at the front and rear by screws. The movement of the sliding seat 401 will drive the indentation strip 8 to move. By adjusting the distance between multiple sliding seats 401, the distance between multiple indentation strips 8 can be adjusted to achieve the adjustment of the indentation spacing.

[0028] The telescopic mechanism 5 includes a connecting rod 501, and a plurality of connecting rods 501 are cross-rotatably connected to form a scissor-type telescopic structure. Both ends of the connecting rod 501 are rotatably connected with a pin shaft 502. A slider 503 is welded on one side of the pin shaft 502 close to the sliding seat 401. The upper and lower sliders 503 are slidably connected in the same longitudinal sliding groove 402. When the telescopic mechanism 5 is extended as a whole, the upper and lower sliders 503 approach each other, and the distance between the two adjacent sliding seats 401 becomes larger.

[0029] The control mechanism 6 includes two connecting plates 601, which are fixedly connected to the top of the sliding seats 401 on both sides. A bidirectional screw rod 602 is connected to the connecting plate 601 through a thread, and the two ends of the bidirectional screw rod 602 are connected to a support 603 through a bearing. The support 603 is connected to the two sides of the pressing plate 3 through screws. The two connecting plates 601 are driven to move away from or closer to each other by rotating the bidirectional screw rod 602, so that the connecting plates 601 drive the sliding seats 401 on both sides to move away from or closer to each other, and the telescopic mechanism 5 is correspondingly lengthened or shortened to ensure that the distance between the two adjacent sliding seats 401 is the same, so as to achieve equidistant adjustment of the indentation strip 8. A handle 604 is welded at one end of the bidirectional screw rod 602.

[0030] A scale line 9 is provided on the front edge of the top of the pressing plate 3, and an indicator head 404 is fixedly connected to the top of the sliding seat 401, and the arrow of the indicator head 404 points to the scale line 9. The spacing of the indentation strips 8 can be adjusted conveniently through the indicator head 404 and the scale line 9;

[0031] The clamping mechanism 7 includes a fixed seat 701, which is connected to the top of the workbench 1 by screws, and a cylinder 702 is connected to one side of the fixed seat 701 by bolts, and the output shaft of the cylinder 702 is fixedly connected to a clamping plate 703, and the cylinders 702 on both sides simultaneously drive the clamping plate 703 to move, clamping and fixing the corrugated cardboard;

[0032] The pressing mechanism 2 includes a fixed frame 201, which is connected to the top of the workbench 1 by bolts. The top wall of the fixed frame 201 is connected to a hydraulic cylinder 202 by bolts. The output shaft of the hydraulic cylinder 202 is fixedly connected to the top of the pressing plate 3. A plurality of guide rods 203 are slidably connected inside the top of the fixed frame 201. The bottom of the guide rod 203 is fixedly connected to the top of the pressing plate 3. The pressing plate 3 can be stably moved up and down through the guide rod 203.

[0033] Working principle: when in use, the corrugated cardboard is placed on the top of the workbench 1, and the cylinder 702 drives the clamping plate 703 to move, so that the clamping plates 703 on both sides clamp and fix the corrugated cardboard, and then the hydraulic cylinder 202 drives the pressing plate 3 to move downward, so that the indentation strip 8 moves downward to perform indentation operation on the corrugated cardboard. For different corrugated cardboards, when the indentation spacing needs to be adjusted, the bidirectional screw rod 602 is rotated by the handle 604, and the bidirectional screw rod 602 drives the two connecting plates 601 to approach or move away from each other, and the two connecting plates 601 drive the sliding seats 401 on both sides to approach or move away from each other, so that the telescopic mechanism 5 is shortened or elongated as a whole, so that the distance between each sliding seat 401 increases or decreases at the same time, and the sliding seat 401 drives the indentation strip 8 to move through the mounting block 403, thereby realizing the equidistant adjustment of the distance between the indentation strips 8, and the adjustment distance can be quickly and conveniently determined through the indicator head 404 and the scale line 9, thereby improving the convenience of use.
