Description

Technical Field

[0001] This invention relates to the field of pearl cotton processing, and in particular to a pearl cotton cutting device. Background Technology

[0002] Pearl cotton is a new type of environmentally friendly packaging material. It is made of low-density polyethylene resin through physical foaming to produce countless independent air bubbles. It overcomes the shortcomings of ordinary foam, such as fragility, deformation, and poor resilience. It has many advantages such as water and moisture resistance, shock resistance, sound insulation and heat preservation, good plasticity, strong toughness, recyclability, environmental protection, and strong impact resistance. It also has good chemical resistance and is an ideal substitute for traditional packaging materials.

[0003] After the EPE foam is produced, it needs to be cut into different shapes as needed. Some existing cutting devices have a device to fix the EPE foam, while others do not. Without a fixing device, the cutting will result in uneven cuts and large dimensional errors. With a fixing device, corresponding fixing components and drivers need to be configured, which increases the investment in equipment and costs. Summary of the Invention

[0004] The purpose of this invention is to provide a pearl cotton cutting device.

[0005] The technical problem of this invention is mainly solved by the following technical solution:

[0019] The technical solution of the present invention will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0020] A pearl cotton cutting device includes a machine base 1 and a cutting mechanism 2 suspended above the machine base 1. The machine base 1 has a cutting groove 3 longitudinally arranged on its top. The cutting mechanism 2 includes a C-shaped frame 21 arranged directly above the cutting groove 3. The C-shaped frame 21 is upside down and has a hot melt wire 22 in its bottom opening. A limit plate 23 is fixed to the top of the C-shaped frame 21 by a vertical rod 24. The limit plate 23 is connected to a mounting frame 26 by a square rod 25. The mounting frame 26 is driven by a hydraulic rod 27. An mounting plate 28 is also arranged above the limit plate 23 for the square rod 25 to pass through. A spring (not shown in the figure) is sleeved on the square rod 25 above the mounting plate 28. Pressure rods 29 are arranged at the bottom of the mounting plates 28 on both sides of the limit plate 23. Pressure plates 210 are arranged at the bottom of the pressure rods 29.

[0021] A collection box 4 is provided on the outer side of the downstream end of the machine platform 1. A support plate 5 on the same side as the collection box 4 is hinged to the top of one side of the machine platform 1. A triangular base 6 is provided at the bottom of the support plate 5. A support seat 7 is provided at the bottom of the base 6, which abuts against its bottom slope. A lead screw 8 driven by a motor 9 is provided on the support seat 7. A slide rod 10 connected to the machine platform 1 is also provided on the support seat 7 directly below the lead screw 8. A U-shaped notch 11 is provided at one end of the support plate 7 and the base 6 along its length direction, which is directly opposite the lead screw 8.

[0022] In this embodiment, the hot melt wire 22 is located directly above the opening of the cutting groove 3, and the machine base 1 is located directly below the opening of the shaped frame 21.

[0023] In this embodiment, two sets of pressure plates 210 are located on both sides of the shaped frame 21 and the cutting groove 3, respectively, and the bottom of the pressure plate 210 is lower than the bottom horizontal plane of the hot melt wire 22.

[0024] In this embodiment, the mounting plate 28 is provided with a square hole for the square rod 25 to pass through. This method can prevent the mounting plate 28 from rotating on the square rod 25. The mounting plate 28 is fixedly connected to the mounting frame 26 through the telescopic rod 12.

[0025] like Figure 1 As shown, the base 6 is a right-angled triangle, one right-angled side wall of the base 6 is fixedly connected to the bottom of the support plate 5, the hypotenuse side wall of the base 6 is set on the same side as the machine base 1, the support seat 7 is a right-angled trapezoidal structure, and the hypotenuse of the support seat 7 is set parallel to the hypotenuse of the bottom of the base 6.

[0026] In this embodiment, the support base 7 is provided with a screw hole for screwing the lead screw 8, and the support base 7 is provided with a sliding hole for the slide rod 10 to pass through. The lead screw 8 and the slide rod 10 are both located directly below the opening of the U-shaped notch 11.

[0027] The method of using this invention is as follows: Pearl cotton is placed on the machine base 1, with one end extending above the support plate 5. When the cutting position of the pearl cotton is directly above the cutting groove 3, the hydraulic rod 27 drives the mounting frame 26 to move the square rod 25, the limiting plate 23, the vertical rod 24, the U-shaped frame 21, and the hot melt wire 22 downwards. During this process, the mounting frame 26, through a spring, drives the mounting plate 28 to first contact the pressure plate 210 on the pressure rod 29 with the top surface of the pearl cotton, thereby squeezing and fixing the end faces of the pearl cotton on both sides of the cutting groove 3. When the mounting frame 26... The square rod 25, the limiting plate 23 and the vertical rod 24 continue to drive the C-shaped frame 21 and the heated hot melt wire 22 to continue to move downward. At this time, the square rod 25 will move downward in the square hole on the mounting plate 28. At the same time, the mounting frame 28 compresses the spring during the downward movement. After the spring is compressed, the pearl cotton on both sides of the cutting groove 3 can be pressed more firmly through the mounting plate 28, the pressure rod 29 and the pressure plate 210. The hot melt wire 22 moves downward to cut the pearl cotton and slides into the cutting groove 3, so that it can completely cut the pearl cotton. Then the cutting mechanism 2 moves upward to reset.

[0028] like Figure 2 , 3 As shown, after the cutting is completed, the cutting mechanism 2 resets. At this time, the motor 9 drives the lead screw 8 to rotate in the screw hole on the support seat 7, so as to drive the support seat 7 to move towards the machine platform 1. The sliding hole on the support seat 7 slides on the slide rod 10. As the support seat 7 gradually loses its supporting and fixing effect, under the gravity pull of the support plate 5 and the base 6, the support plate 5 rotates clockwise with the hinge as the center, so that the support plate 5 and the base 6 rotate downward. At this time, the U-shaped notch 11 is fastened on the lead screw 8 and the slide rod 10. At the same time, the right end of the support plate 5 slides into the collection box 4. At this time, the pearl cotton cut above the support plate 5 can flow into the collection box 4 along its top slope. Then, the motor 9 drives the lead screw 8 to rotate in the screw hole on the support seat 7, so as to drive the support seat 7 to move to the right and gradually contact the bottom slope of the base 6. By pushing the base 6, the support plate 5 is driven to rotate counterclockwise with the hinge as the center, so that the support plate 5 is in a horizontal state and parallel to the top of the machine platform 1. Then, the above steps are repeated to move the pearl cotton to cut it.

[0029] The present invention has been described in detail above, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
