Description

Technical Field

[0001] The utility model relates to the technical field of carton printing and slotting machine accessories, in particular to a creasing device of a corrugated carton printing and slotting machine. Background Art

[0002] Corrugated cardboard is the most widely used packaging product, and its usage has always been the highest among all packaging products. With its superior performance and good processing performance, corrugated cardboard has gradually replaced wooden boxes and other transport packaging containers, becoming the main force of transport packaging. Generally, when producing corrugated cardboard, it is necessary to slot and splice the cardboard. Before the slotting machine is used, the cut groove printing needs to be pre-pressed to ensure the smoothness and stability of the slotting work. The pressing device of the existing corrugated cardboard printing and slotting machine on the market has disadvantages in its use. The device is not convenient for batch blanking of mass-produced corrugated cardboard, resulting in extremely low production efficiency.

[0003] The mechanism that this invention relates to is that the present invention relates to a paper making machine which is convenient for carrying out paper making, and it is an object of this invention to provide a paper making machine with an easy-to-use method for making paper making.

[0004] The above patent also has certain shortcomings. In the wire pressing mechanism of the device, the flip roller is rotatably installed inside the flip plate, and two wire pressing sleeves are provided on the outer wall of the flip roller. The two wire pressing sleeves are threadedly connected with positioning bolts. The wire pressing sleeve can be adjusted on the flip roller by the positioning bolts, and then the flip roller is tightened by the positioning bolts to fix the wire pressing sleeve. This can indeed fix the wire pressing sleeve, but the bottom of the positioning bolt is flat, and the surface of the flip roller is an arc surface. The flat and arc surfaces are not reliably tightened, and slipping is easy to occur, resulting in poor fixing effect of the wire pressing sleeve, and it is easy to cause the wire pressing sleeve to rotate circumferentially on the flip roller, making it difficult for the flip roller to drive the wire pressing sleeve to rotate, affecting normal wire pressing. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a crimping device of a corrugated cardboard printing and slotting machine that can effectively improve the fixing effect of the crimping sleeve, prevent the crimping sleeve from rotating circumferentially on the flip roller, make it easier for the flip roller to drive the crimping sleeve to rotate, and avoid affecting the normal crimping.

[0006] Technical Solution

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wire pressing device of a corrugated cardboard box printing and slotting machine, comprising a turning roller and a wire pressing structure rotatably installed inside a flip plate, the wire pressing structure comprising two groups of wire pressing sleeves, both groups of wire pressing sleeves are integrally fixed with wire pressing rings, both groups of wire pressing sleeves are integrally fixed with limit blocks on the top of the inner wall, two groups of limit guide grooves are symmetrically provided on the outer wall of the top of the turning roller, the two groups of wire pressing sleeves are symmetrically slidably sleeved on the turning roller through the cooperation of the limit blocks and the limit guide grooves, each group of wire pressing sleeves and the limit blocks are provided with threaded holes, both groups of threaded holes are screwed with positioning bolts, both groups of positioning bolts are fixed with screw caps on the top, and both groups of screw caps are symmetrically fixed with two groups of screw pieces.

[0008] Preferably, steel rulers are fixedly provided in the two sets of limiting guide grooves, and scales are engraved on the top of the two sets of steel rulers.

[0009] Preferably, the two groups of positioning bolts are both provided with anti-loosening springs, and the top ends of the two groups of anti-loosening springs are fixedly connected to the bottom ends of the two groups of screw caps respectively.

[0010] Preferably, anti-slip rubber pads are fixedly provided on the front and rear ends of the four groups of twisting pieces.

[0011] Preferably, the bottom ends of the two groups of positioning bolts are fixedly connected with fastening rubber pads.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: when in use, the bottom end of the positioning bolt is initially tightly against the bottom end of the limiting guide groove, the bottom end of the positioning bolt is flat, and the bottom end of the limiting guide groove is also flat. The flat surfaces are pressed tightly against each other, which can make the contact surface larger and less likely to slip. When the position of the wire pressing sleeve needs to be adjusted, the hand pinches the twist piece and rotates the positioning bolt through the screw cap to loosen the positioning bolt, and then the position of the wire pressing sleeve can be slid to adjust. After the position of the wire pressing sleeve is adjusted, the positioning bolt is tightened again. Through the guiding cooperation of the limiting block and the limiting guide groove, the wire pressing sleeve can only slide along the axial direction and will not produce circumferential rotation, thereby effectively improving the fixing effect of the wire pressing sleeve, preventing the wire pressing sleeve from producing circumferential rotation on the flip roller, and making it easier for the flip roller to drive the wire pressing sleeve to rotate, thereby avoiding affecting normal wire pressing.

[0019] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] Example

[0021] See also Figure 1-Figure 5The utility model relates to a crimping device of a corrugated cardboard box printing and slotting machine, comprising a turning roller 1 rotatably mounted inside a flap, two sets of crimping sleeves 2 are integrally fixed with crimping rings 3, the tops of the inner walls of the two sets of crimping sleeves 2 are integrally fixed with limit blocks 4, two sets of limit guide grooves 5 are symmetrically provided on the outer wall of the top of the turning roller 1, the two sets of crimping sleeves 2 are symmetrically slidably sleeved on the turning roller 1 through the cooperation of the limit blocks 4 and the limit guide grooves 5, each set of crimping sleeves 2 and the limit blocks 4 are provided with threaded holes 6, and the two sets of threaded holes 6 are screwed with positioning bolts 7, the tops of the two sets of positioning bolts 7 are fixed with screw caps 8, and the two sets of screw caps 8 are symmetrically fixed with two sets of screw pieces 9; when in use, the bottom ends of the positioning bolts 7 are initially tightly fastened. When the position of the wire sleeve 2 needs to be adjusted, the hand pinches the screw piece 9 and rotates the positioning bolt 7 through the screw cap 8 to loosen the positioning bolt 7, and then the position of the wire sleeve 2 can be slidably adjusted. After the position of the wire sleeve 2 is adjusted, the positioning bolt 7 is tightened again. Through the guiding cooperation of the limit block 4 and the limit guide groove 5, the wire sleeve 2 can only slide along the axial direction and will not rotate circumferentially, thereby effectively improving the fixing effect of the wire sleeve and preventing the wire sleeve from rotating circumferentially on the flip roller, making it easier for the flip roller to drive the wire sleeve to rotate, and avoiding affecting the normal wire pressing.

[0022] A steel ruler 10 is fixed in each of the two groups of limiting guide grooves 5, and scales are engraved on the top of each group of steel rulers 10; by setting the steel ruler 10, when adjusting the position of the wire pressing sleeve 2, the position of the wire pressing sleeve 2 is adjusted by the scale on the steel ruler 10 and the indication on the inner side of the wire pressing ring 3, so that the inner side of the wire pressing ring 3 is indicated on the same scale of the steel ruler 10, thereby ensuring that the two groups of wire pressing sleeves 2 can be symmetrically distributed on both sides of the flip roller 1.

[0023] The two groups of positioning bolts 7 are both provided with anti-loosening springs 11, and the top ends of the two groups of anti-loosening springs 11 are fixedly connected to the bottom ends of the two groups of screw caps 8 respectively; by providing the anti-loosening springs 11, when the positioning bolts 7 are tightened by the screw caps 8, the screw caps 8 move downward to compress the anti-loosening springs 11, and the compression of the anti-loosening springs 11 generates an axial thrust, so that the threads on the positioning bolts 7 are tightly matched with the threads on the threaded holes 6, effectively preventing the positioning bolts 7 from loosening.

[0024] Anti-skid rubber pads 12 are fixed to the front and rear ends of the four groups of twisting pieces 9. The anti-skid rubber pads 12 can prevent the twisting pieces 9 from slipping when the positioning bolts 7 are rotated by the hands.

[0025] The bottom ends of the two groups of positioning bolts 7 are fixedly connected with fastening rubber pads 13; by providing the fastening rubber pads 13, the friction of the bottom ends of the positioning bolts 7 can be increased, so that the positioning bolts 7 can fit more closely with the bottom ends of the limiting guide grooves 5 when tightened, further preventing slipping.

[0026] When the position of the wire pressing sleeve 2 needs to be adjusted, the hand pinches the screw piece 9 and rotates the positioning bolt 7 through the screw cap 8 to loosen the positioning bolt 7, and then the position of the wire pressing sleeve 2 can be slidably adjusted. After the position of the wire pressing sleeve 2 is adjusted, the positioning bolt 7 is tightened again. Through the guiding cooperation of the limiting block 4 and the limiting guide groove 5, the wire pressing sleeve 2 can only slide along the axial direction and will not rotate circumferentially, thereby effectively improving the fixing effect of the wire pressing sleeve and preventing the wire pressing sleeve from rotating circumferentially on the flip roller.
