Detailed Description

The embodiments of the invention will be further described with reference to the accompanying drawings in which:

referring to fig. 1 and fig. 2-7, a die cutting device includes a die cutting frame 51, a die cutting driving member 52 and a die cutting roller set 53 are arranged on the die cutting frame 51, the die cutting roller set 53 includes a first die cutting roller shaft 531 and a second die cutting roller shaft 532, the die cutting driving member 52 is connected with the die cutting roller set 53 and drives the first die cutting roller shaft 531 and the second die cutting roller shaft 532 to rotate and mutually cooperate for die cutting materials, and a die cutting negative pressure component 54 for generating negative pressure to enable the materials to cling to the first die cutting roller shaft 531 is arranged on the first die cutting roller shaft 531. The die-cutting negative pressure assembly has the advantages that the die-cutting negative pressure assembly is arranged, so that materials can be attached reliably when a product is die-cut, the materials cannot shift when the product is die-cut, and the die-cutting of the product is reliable. The invention also has the advantages of simple structure, convenient assembly, reliable action, long service life and the like. Specifically, the die-cutting driving piece can drive the first die-cutting roller shaft and/or the second die-cutting roller shaft to rotate. Namely, the first die-cutting roll shaft or the second die-cutting roll shaft is used as a driving shaft, and the other roll shaft is not moved or is driven to rotate. It is of course also possible to rotate the first and second die-cutting roller shafts in phase or in opposite directions, i.e. the die-cutting drive element rotates the die-cutting roller group by means of a belt drive or a chain drive or a gear drive. According to the die-cutting device, the die-cutting driving piece is connected with the first die-cutting roll shaft and drives the first die-cutting roll shaft to rotate, and the first die-cutting roll shaft drives the second die-cutting roll shaft to rotate through gear transmission.

The die cutting negative pressure component 54 comprises a gas distribution disc 541, a gas distribution groove 5411 is arranged on the gas distribution disc 541, a plurality of first gas distribution holes 5311 are arranged on the first die cutting roller shaft 531, and the first gas distribution holes 5311 are communicated with the gas distribution groove 5411 in the gas distribution disc 541 when receiving materials and generate a first position enabling the materials to be tightly attached to the first die cutting roller shaft 531 and a second position isolated from the gas distribution groove 5411. Specifically, the two positions of the first air distribution holes are that a specific first air distribution hole(s) has two positions when receiving or discharging materials, but not all the first air distribution holes are necessarily in the same first position or second position, that is, the air distribution groove on the air distribution plate can be communicated with a part of the first air distribution holes to enable the first air distribution holes to be in the first position, and the air distribution groove on the air distribution plate can be isolated from a part of the first air distribution holes to enable the first air distribution holes to be in the second position, so that a part of the first air distribution holes can provide negative pressure to facilitate receiving materials by the other part of the first air distribution holes when die cutting and feeding materials, and the processing efficiency of products is improved. Of course, in actual production, all the first air distribution holes may be in the first position or the second position. The die-cutting negative pressure component can provide negative pressure for the first die-cutting roller shaft, materials are attached to the first die-cutting roller shaft during die cutting, the material is prevented from being displaced to cause material waste and waste is prevented from being produced when the die cutting is carried out to a heat-sealing position, and the die-cutting negative pressure component has the function of tensioning during die cutting to a certain extent, so that the die cutting is reliable. The setting up of gas distribution groove makes the product can provide lasting suction simultaneously, and the material after having cut promptly can not the free fall (because the non-woven fabrics is lighter, can cause the offset to be unfavorable for subsequent processing during the free fall), but continues to provide the negative pressure through first gas distribution hole, finally after the terminal negative pressure suction in gas distribution groove cancels, just can make the material fall in the position of being convenient for to collect promptly. More specifically, the die cutting usually occurs in the middle or upper part of the first die cutting roller, and the arrangement of the first air distribution hole and the die cutting negative pressure component enables the material to be still attached to the first die cutting roller after the die cutting until the material is put down at a proper position. In the invention, the die-cut material is transferred to the lower part (or the middle lower part) of the first die-cutting roller shaft and is released, so that the position of the freely falling material is prevented from being deviated, and the subsequent processing is not facilitated.

The first die-cutting roll shaft 531 is provided with a plurality of air distribution channels 5312, and each air distribution channel 5312 is arranged corresponding to the plurality of first air distribution holes 5311. Specifically, the air distribution channels 5312 are arranged corresponding to the two rows of the first air distribution holes 5311, and the air distribution channels 5312 and the first air distribution holes 5311 are arranged in a V-shaped cross section. The structure can reliably realize the adsorption of materials, and is convenient for the reliable and continuous processing of products.

The air distribution groove 5411 is arranged in an arc shape, the first die cutting roll shaft 531 is provided with second air distribution holes 5313, and the second air distribution holes 5313 are arranged on two sides of the first air distribution holes 5311. The middle of the finger sleeve is wide, two ends of the finger sleeve are sharp, so that the two ends of the finger sleeve can be adsorbed and positioned only by one hole, the product structure is simplified, and the reliable adsorption of the product is realized.

The second die-cutting roll shaft 532 is provided with a die-cutting knife 5321 for die-cutting materials, the die-cutting knife 5321 is wrapped by a soft wrapping piece 5322, and the die-cutting knife 5321 is provided with a first position and a second position for die-cutting during installation. Specifically, the soft covering member may be rubber. The soft covering piece can be used for positioning the second material during die cutting, so that the displacement of the material during die cutting is avoided. Specifically, the horizontal height of the soft wrapping member 5322 is higher than the horizontal height of the die cutting knife 5321, and the die cutting knife 5321 extends out of the soft wrapping member 5322 when in the second position for die cutting of the material. More specifically, the soft cladding piece can also avoid the influence of static electricity and the like on the material and avoid the material from shifting. The positioning can be realized through rubber during die cutting, and the coated die-cutting rule can still reliably perform die cutting when in use.

The invention also comprises a first traction mechanism 55, a heat sealing mechanism 56 and a second traction mechanism 57, wherein the heat sealing mechanism 56 is arranged between the first traction mechanism 55 and the second traction mechanism 57. Specifically, the first drawing mechanism 55 includes a first drawing roller set 551, the second drawing mechanism 57 includes a second drawing roller set 571, and the rotation speed of the second drawing roller set 571 is slower than that of the die cutting roller set 53. More specifically, the heat sealing mechanism 56 includes an ultrasonic welding roller 561, and the first and second traction roller sets 551 and 571 rotate synchronously at a slower speed than the ultrasonic welding roller 561. The arrangement of the traction mechanism and the heat sealing mechanism ensures that the product is reliable in feeding and heat sealing, and is convenient for continuous processing of the product. In the actual production process, the speed of the traction mechanism is slightly lower than the speeds of the die-cutting roller group and the heat-sealing assembly, so that the tensioning effect can be achieved, reliable die cutting is facilitated, and the heat-sealing effect is better.
