A thin-neck stretching device for monofilament filter material

Abstract

This invention provides a necking device for monofilament filter media, comprising a housing with a stretching cavity inside. Two drive shafts are rotatably connected within the stretching cavity. Two motors are fixedly connected to the housing, with their output shafts fixedly connected to the drive shafts. A first winding roller is fixedly connected to the outer surface of one drive shaft, and a second winding roller is rotatably connected to the outer surface of the other drive shaft. A heating assembly and a cooling assembly are fixedly arranged between the two drive shafts. A first sliding groove is provided on the drive shaft rotatably connected to the second winding roller, and several second sliding grooves are provided on the side of the second winding roller near the drive shaft. This solution improves the necking efficiency by setting a first winding roller with a higher rotational speed than the second winding roller on both sides of the heating and cooling assemblies, and by providing second sliding grooves on the second winding roller that can slidably connect with a locking slider. This allows the rotational speed of the second winding roller to be changed by whether the second sliding grooves are locked to the locking slider.

[0020] like Figure 1-3As shown, it includes a shell 11, a stretching chamber 12 is opened in the shell 11, two driving shafts 13 are rotatably connected in the stretching chamber 12, two motors 14 are fixedly connected to the shell 11, the output shaft of the motor 14 is fixedly connected to the driving shaft 13, a first winding roller 15 is fixedly connected to the outer circumferential surface of one driving shaft 13, and a second winding roller 16 is rotatably connected to the outer circumferential surface of the other driving shaft 13, a heating component and a cooling component are fixedly arranged between the two driving shafts 13, a first sliding groove 25 is opened on the driving shaft 13 rotatably connected to the second winding roller 16, a plurality of second sliding grooves 26 are opened on the surface of the second winding roller 16 close to the driving shaft 13, a locking slider 27 is slidably connected in the first sliding groove 25, the length of the locking slider 27 is equal to that of the first sliding groove 25, the length of the locking slider 27 is greater than the length of the second sliding groove 26, and chamfers are arranged on both sides of the locking slider 27 close to one end of the second winding roller 16.

[0021] It is noteworthy that the rotation speed of the driving shaft 13 provided with the first winding roller 15 is greater than the rotation speed of the driving shaft 13 provided with the second winding roller 16 .

[0022] When the driving shaft 13 drives the second winding roller 16 to rotate until the first winding roller 15 is at the upper limit position, the locking slider 27 slides into the first sliding groove 25, and the first sliding groove 25 and the second sliding groove 26 are unlocked. At this time, the second winding roller 16 is pulled by the monofilament filter material, and the rotation speed of the second winding roller 16 is equal to the rotation speed of the first winding roller 15.

[0023] When the driving shaft 13 drives the second winding roller 16 to rotate until the first winding roller 15 is at the lower limit position, the locking slider 27 slides into the second sliding groove 26, and the first sliding groove 25 and the second sliding groove 26 are locked. At this time, the rotation speed of the first winding roller 15 is greater than the rotation speed of the second winding roller 16.

[0024] The heating assembly comprises a heating base 17 . A heating block 20 is fixedly arranged on the heating base 17 at the level of the driving shaft 13 . A heating cavity 21 is defined in the heating block 20 .

[0025] The cooling assembly includes a cooling base 18, which is located at the horizontal height of the drive shaft 13 and has a slot. The cooling base 18 is provided with a cooling cavity 22 that penetrates the slot in the vertical direction. An air-cooling pipe group is fixedly arranged in the cooling cavity 22.

Then, the two motors 14 are started at the same time, and the two motors 14 respectively drive the driving shaft 13 to rotate. Since the locking slider 27 is initially located in the second sliding groove 26, the rotation speed of the first winding roller 15 is greater than the rotation speed of the second winding roller 16. Therefore, the monofilament filter material heated by the heating chamber 21 is stretched by the first winding roller 15. Finally, when the driving shaft 13 drives the second winding roller 16 to rotate until the first winding roller 15 is located at the upper limit position, the locking slider 27 slides into the first sliding groove 25, and the first sliding groove 25 and the second sliding groove 26 are unlocked. At this time, the second winding roller 16 is pulled by the monofilament filter material, and the rotation speed of the second winding roller 16 is equal to the rotation speed of the first winding roller 15, and the above steps are repeated.
