[0039] The present utility model provides a slitter.

[0040] Please refer to Figure 1 , in an embodiment of the present utility model, the slitter 100 includes: a pipeline assembly 1, a limiting assembly 2, and a cutting assembly 3. The pipeline assembly 1 is provided with a cutting area, and the pipeline assembly 1 is used for conveying tubular EPE. The limiting assembly 2 has two limiting units 21, and the two limiting units 21 are installed on both sides in the width direction of the pipeline assembly 1, located within the cutting area and arranged oppositely. The oppositely arranged parts of the two limiting units 21 are adjustable in the width direction of the pipeline assembly 1 to correspond to different diameters of the tubular EPE. And the cutting assembly 3 is installed corresponding to the cutting area and has a plurality of cutting units 32. The plurality of cutting units 32 are arranged at intervals along the length direction of the pipeline assembly 1 and are movably arranged along the length direction of the pipeline assembly 1 to adjust the interval distance.

[0041] The technical solution of the present utility model conveys tubular EPE by using the pipeline assembly 1 and conveys the tubular EPE to the cutting area. In order to prevent the tubular EPE from bending on the pipeline assembly 1 and unable to ensure the cutting length, it is necessary to limit the tubular EPE. The limiting assembly 2 has two limiting units 21, and the limiting units 21 are installed on both sides of the pipeline assembly 1 in the width direction, located within the cutting area and arranged oppositely. The relatively arranged parts of the two limiting units 21 are adjustable in the width direction of the pipeline assembly 1 to limit tubular EPE with different diameters; then the cutting assembly 3 cuts the tubular EPE located in the cutting area. The cutting assembly 3 has a plurality of cutting units 32, and the plurality of cutting units 32 are arranged at intervals along the length direction of the pipeline assembly 1, and the interval distance is adjustable, so as to cut tubular EPE with different lengths.

[0042] In order to limit the tubular EPE, in one embodiment, the limiting unit 21 includes: a connecting member 211, a first stopper 212 and a second stopper 213; the connecting member 211 extends along the height direction of the pipeline assembly 1 and is fixedly connected to the pipeline assembly 1; so that the whole limiting unit 21 can be fixedly connected to the pipeline assembly 1; the first stopper 212 is adjustably installed on the connecting member 211 along the width direction of the pipeline assembly 1 and at least partially extends along the height direction of the pipeline assembly 1 to limit the tubular EPE in the width direction of the pipeline assembly 1; the second stopper 213 is at least adjustable along the height direction of the pipeline assembly 1 and at least partially extends along the width direction of the pipeline assembly 1 to limit the tubular EPE in the height direction of the pipeline assembly 1.

[0043] Specifically, the connecting member 211 has a first extension portion 2111 extending along the height direction of the pipeline assembly 1, and a first limiting groove 21111 penetrating along the width direction of the pipeline assembly 1 is provided on the first extension portion 2111; the first stopper 212 has a first threaded rod 2121 extending along the width direction of the pipeline assembly 1, the first bolt rod penetrates through the first limiting groove 21111, and a baffle 21224 extending along the height direction of the pipeline assembly 1 is provided at one end of the first threaded rod 2121; the baffle 21224 is used to abut against the tubular EPE, and the two opposite baffles 21224 jointly limit the tubular EPE in the width direction of the pipeline assembly 1. The limiting unit 21 further includes two first nuts 215. After adjusting the position of the baffle 21224, the two first nuts 215 are threadedly connected to the first bolt rod to fix the first stopper 212 to the connecting member 211, so as to fix the position of the baffle 21224.

[0044] To prevent the tubular EPE from arching in the height direction of the assembly line component 1, which may affect the cutting length of the tubular EPE. One end of the first extension part 2111 extends along the width direction of the assembly line component 1 to form the second extension part 2112; the second extension part 2112 is provided with a second limiting groove 21121 extending along the width direction of the assembly line component 1; the second stop member 213 extends integrally along the width direction of the assembly line component 1, and the second stop member 213 further has a third bolt rod 2131 extending along the height direction of the assembly line component 1, and the third bolt rod 2131 passes through the second limiting groove 21121; the third bolt rod 2131 can move along the width direction of the assembly line component 1 and is used to abut against the circumferential position of the upper half of the tubular EPE to limit the tubular EPE. The limiting unit 21 further includes a third nut 217, and the third nut 217 is threadedly connected to the third bolt rod 2131 to fix the second stop member 213 to the connecting member 211. In the specific fixing manner of the connecting member 211, the first limiting groove 21111 is arranged to extend along the height direction of the assembly line component 1; second bolt rods 214 extending in the width direction of the assembly line are provided on both sides in the width direction of the assembly line component 1, and the second bolt rods 214 pass through the first limiting groove 21111; the limiting unit 21 further includes a second nut 216, and the second nut 216 is threadedly connected to the second bolt rod 214 to fix the connecting member 211 to the assembly line component 1.

[0045] In one type of embodiment, the cutting assembly 3 is arranged as follows: the cutting assembly 3 includes a mounting plate 31, a thermal resistance wire 321, and a mounting assembly 322. The mounting plate 31 is provided with two third limiting grooves 311 extending along the length direction of the assembly line component 1; the two third limiting grooves 311 are arranged on both sides in the width direction of the assembly line component 1; the thermal resistance wire 321 is used to cut the tubular EPE; the mounting assembly 322 includes two mounting members 3221, which are respectively adjustably mounted in the two third limiting grooves 311 along the length direction of the assembly line component 1, and the mounting members 3221 can slide along the third limiting members. The two mounting members 3221 are arranged oppositely in the width direction of the assembly line component 1 and are respectively used to fix both ends of the thermal resistance wire 321; one of the mounting assemblies 322 and one thermal resistance wire 321 form a cutting unit 32. The simultaneous sliding of the two mounting members 3221 of a cutting unit 32 can change the position of the thermal resistance wire 321, thereby adjusting the distance between the two thermal resistance wires 321 and thus adjusting the cutting length.

[0046] In order to install the thermal resistance wire 321 on the mounting member 3221 and facilitate the replacement of the thermal resistance wire 321 after subsequent damage, the mounting member 3221 includes a mounting hole 32211, a threaded hole 32212 and a setscrew 32213. The mounting hole 32211 is provided through in the width direction of the pipeline assembly 1 for the thermal resistance wire 321 to pass through; one end of the threaded hole 32212 communicates with the mounting hole 32211 and the other end communicates with the outside; the setscrew 32213 is installed in the threaded hole 32212, and the end extends into the mounting hole 32211 to position the thermal resistance wire 321. When the setscrew 32213 is loosened, the end of the thermal resistance wire 321 can be taken out from the mounting hole 32211.

[0047] In order to stop the movement of the tubular EPE after it reaches the cutting area for easy cutting, the slitter 100 further includes a baffle 21224, which is movably installed along the height direction of the pipeline assembly 1 on one side of the cutting area to block the movement of the tubular EPE. After cutting is completed, the baffle 21224 moves downward along the height direction of the pipeline assembly 1 to enable the cut tubular EPE to continue to flow and enter the next process.

[0048] In order to prevent friction from being generated between the pipeline assembly 1 and the tubular EPE after the baffle 21224 blocks the tubular EPE, causing the tubular EPE to deform and affecting the cutting length and the shape after cutting, it is necessary to pause the pipeline assembly 1 when the tubular EPE abuts against the baffle 21224. The slitter 100 further includes a sensor and a controller. The controller is electrically connected to the sensor and the pipeline assembly 1 respectively. The sensor is arranged on the baffle 21224 to emit an electrical signal when the tubular EPE abuts against the baffle 21224. After receiving the electrical signal, the controller stops the operation of the pipeline assembly 1, and after completing the cutting action and lowering the baffle 21224, the pipeline assembly 1 is restarted.

[0049] In order to better limit the tubular EPE to extend in a straight line direction, a plurality of limiting components 2 are provided and arranged at intervals along the length direction of the pipeline assembly 1.

[0050] In order to prevent the limiting component 2 from hindering the downward movement of the cutting unit 32, a plurality of limiting components 2 are arranged at intervals along the length direction of the pipeline assembly 1, and a plurality of cutting units 32 are respectively located in the gaps between the plurality of limiting components 2.
