Description

Technical Field

[0001] The utility model relates to the technical field of non-woven fabric processing equipment, in particular to a point-breaking component structure of a point-breaking slitting machine. Background Art

[0002] Non-woven fabrics, also known as non-woven fabrics, needle-punched cotton, etc., are made of directional or random fibers. They are called cloth because they have the appearance and certain properties of cloth. Non-woven fabrics are moisture-proof, breathable, flexible, lightweight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in colors, low in price, and recyclable. For example, polypropylene (pp material) pellets are often used as raw materials, and are produced in a continuous one-step process of high-temperature melting, spinning, laying, hot pressing and winding. In the production process of non-woven fabrics, a point-breaking slitting machine is required to cut them.

[0003] When the non-woven fabric is point-cut in the existing non-woven fabric point-cutting folding machine, a point-cutting knife is generally directly set on the point-cutting roller, and a corresponding knife groove is set on another point-cutting roller, so that the non-woven fabric can be point-cut under the coordinated action of the point-cutting knife and the point-cutting roller. However, this method can only point-cut the non-woven fabric, and cannot form an indentation at the point-cutting position, so that when the non-woven fabric is torn during use, stratification is easily formed at the breaking point. Utility Model Content

[0004] The purpose of the utility model is to provide a point-breaking component structure of a point-breaking slitting machine, which can compact the non-woven fabric when performing point-breaking operations on the non-woven fabric, reduce the technical problem of stratification at the breaking point during use, and is convenient for tearing the non-woven fabric for use.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A point breaking assembly structure of a point breaking slitting machine comprises a first roller and a second roller for being mounted on a frame, the first roller and the second roller are connected via a transmission mechanism, the first roller is provided with a point breaking assembly, and the second roller is provided with a knife letting groove;

[0007] The point breaking assembly includes a base, a pressure plate and a plurality of point breaking knives. A mounting groove is provided on the first roller, and the base is fixedly installed in the mounting groove. A slide groove is provided on the base, and the pressure plate is slidably arranged in the slide groove. A reset member connected with the pressure plate is provided in the slide groove. A plurality of guide grooves are provided on the pressure plate. The point breaking knives are fixedly installed in the guide grooves and slidably cooperate with the guide grooves. The knife grooves provided on the second roller correspond to the point breaking knives.

[0008] Wherein, the knife groove is an annular groove arranged on the side of the second roller.

[0009] Furthermore, a T-shaped slot is arranged on the side of the first roller, the T-shaped slot is connected to the mounting slot, a T-shaped limiting portion corresponding to the T-shaped slot is arranged on the base, and the T-shaped limiting portion is fixed with screws after being installed in the T-shaped slot.

[0010] Preferably, the mounting groove is a dovetail groove.

[0011] Furthermore, the reset element is a reset spring.

[0012] Wherein, the transmission mechanism is a gear transmission mechanism.

[0013] Furthermore, the slide groove includes a first slide groove and a second slide groove, a limiting surface is formed at the connection position of the first slide groove and the second slide groove, and limiting protrusions are arranged on both sides of the pressure plate. After the limiting protrusions contact with the limiting surface, the pressure plate is limited.

[0014] The top of the pressing plate has an arc-shaped portion, and the curvature radius of the arc-shaped portion is the same as the curvature radius of the first roller.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] The utility model arranges the base and the pressing plate in a sliding manner so that the pressing plate can move after being pressed. When performing the point breaking operation, the first roller and the second roller can rotate simultaneously under the action of the transmission mechanism, and the rotation speeds are the same. A gap is formed between the first roller and the second roller. When the non-woven fabric is point broken through the gap, the pressing plate follows the rotation and presses the non-woven fabric on the surface of the second roller, thereby compacting the point breaking position of the non-woven fabric. The pressing plate is reset after being pressed, and at this time the point breaking knife can extend out of the pressing plate and extend into the knife groove, so that the point breaking and compaction of the non-woven fabric can be achieved, and an indentation can be formed at the point breaking position.

[0030] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0031] See also Figure 1-Figure 4 This embodiment discloses a point breaking component structure of a point breaking slitting machine, including a first roller 101 and a second roller 102 for being mounted on a frame, the first roller 101 and the second roller 102 are connected via a transmission mechanism, a point breaking component 103 is arranged on the first roller 101, and a knife groove 104 is arranged on the second roller, and the frame is a frame of the point breaking slitting machine;

[0032] Among them, the point breaking component 103 includes a base 105, a pressure plate 106 and a plurality of point breaking knives 107. A mounting groove 108 is provided on the first roller 101. The base 105 is fixedly installed in the mounting groove 108. A slide groove 109 is provided on the base 105. The pressure plate 106 is slidably set in the slide groove 109. A reset member 110 connected to the pressure plate 106 is provided in the slide groove 109. A plurality of guide grooves are provided on the pressure plate 106. The point breaking knife 107 is fixedly installed in the guide groove and slidably cooperates with the guide groove; the knife groove 104 provided on the second roller corresponds to the point breaking knife 107.

[0033] The utility model sets the base 105 and the pressing plate 106 to slide, so that the pressing plate 106 can move after being pressed. When the point breaking operation is performed, the first roller 101 and the second roller 102 can rotate at the same time under the action of the transmission mechanism, and the rotation speed is the same. A gap is formed between the first roller 101 and the second roller 102. When the non-woven fabric is point broken through the gap, the pressing plate 106 follows the rotation and presses the non-woven fabric on the surface of the second roller to achieve compaction of the non-woven fabric at the point breaking position. The pressing plate 106 is reset after being pressed, and the point breaking knife 107 can extend out of the pressing plate 106 and extend into the knife groove 104. In this way, the point breaking and compaction of the non-woven fabric can be achieved, and an indentation can be formed at the point breaking position.

[0034] Furthermore, by making the knife groove 104 an annular groove disposed on the side of the second roller 102, the installation accuracy of the second roller 102 can be reduced and the installation efficiency can be improved.

[0035] A T-shaped slot 111 is provided on the side of the first roller, and the T-shaped slot 111 is connected to the mounting slot 108. A T-shaped limiting portion 112 corresponding to the T-shaped slot 111 is provided on the base 105. The T-shaped limiting portion 112 is installed in the T-shaped slot 111 and fixed with screws.

[0036] In this way, the base 105 can be positioned, making installation more convenient.

[0037] The mounting groove 108 is a dovetail groove, which can limit the base 105 .

[0038] The reset member 110 is a reset spring. In actual use, the spring may have a larger elastic coefficient so that the pressure of the pressing plate 106 is greater to ensure the formation of an indentation on the non-woven fabric.

[0039] The transmission mechanism is a gear transmission mechanism, so that the rotation speeds of the first roller 101 and the second roller 102 are the same.

[0040] Among them, the slide groove 109 includes a first slide groove 113 and a second slide groove 114, and a limiting surface is formed at the connecting position of the first slide groove 113 and the second slide groove 114. Limiting protrusions are arranged on both sides of the pressure plate 106. After the limiting protrusions contact with the limiting surface, the pressure plate 106 is limited, which can achieve the limitation of the pressure plate 106.

[0041] Furthermore, the top of the pressing plate 106 has an arc-shaped portion 115, and the curvature radius of the arc-shaped portion 115 is the same as the curvature radius of the first roller 101. In this way, the pressing plate 106 can be flush with the surface of the first roller after being pressed, and the non-woven fabric can pass more smoothly.
