Description

Technical Field

[0001] This utility model belongs to the field of cotton swab processing, specifically relating to a paper grinding shaft mechanism. Background Technology

[0002] In the cotton swab manufacturing industry, the paper shaft, as the core carrier for fixing the cotton head, requires high-precision grinding at both ends to form a conical structure suitable for covering the cotton head.

Detailed Implementation

[0023] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0024] like Figures 1 to 10 As shown, this utility model provides a paper grinding shaft mechanism, which includes a frame 1. A feeding device 3 for placing paper shafts 2 and a pushing device 4 for pushing the paper shafts 2 are mounted on the frame 1. The pushing device 4 is located below the feeding device 3. A distribution device 5 for distributing the paper shafts 2 is located on one side of the pushing device 4. A moving wheel assembly 6 for transporting the paper shafts 2 is located on one side of the distribution device 5. A grinding device 7 for grinding both ends of the paper shafts 2 is located above the moving wheel assembly 6. The grinding device 7 is connected to an adjusting device 8 for adjusting the position of the grinding device 7.

[0025] The feeding device 3 includes two positioning plates 31 mounted on the frame 1. A first baffle 32 and a second baffle 33 are positioned between the two positioning plates 31. The second baffle 33 is inclined above the pushing device 4. A discharge port 34 is provided at the bottom of the first baffle 32 and the second baffle 33. In use, several paper rolls 2 are stacked between the first baffle 32 and the second baffle 33, and the ends of the paper rolls 2 are aligned by the positioning plates 31. The paper puller 2 falls through the discharge port 34 to the pushing device 4 below, and the pushing device 4 can be used to transport the paper rolls 2 to the dispensing device 5.

[0026] Furthermore, the pushing device 4 includes a pushing plate 41 disposed below the discharge port 34. The front end of the pushing plate 41 is inclined downward, and a pushing end 42 is provided at the front end of the pushing plate 41. The pushing end 42 is located at the distribution device 5 and can deliver the paper roll 2 of the pushing plate 4 to the distribution device 5 for distribution. The rear end of the pushing plate 41 is hinged to the push rod 43, and the push rod 43 is eccentrically connected to the shaft 44 of the drive motor (not shown). A slider 45 is provided at the bottom of the pushing plate 41, and a guide rail 46 is provided below the slider 45 to move the slider 45 back and forth. The guide rail 46 is disposed on the frame 1. In use, the push rod 43 is driven by the drive motor to push the pushing plate 41 back and forth to transport the paper roll 2 to the distribution device 5.

[0027] Furthermore, the dispensing device 5 includes two coaxially arranged and rotatable dispensing wheels 51. The outer circumference of each dispensing wheel 51 has several slots 52 for holding paper shafts 2. The slots 52 of the two dispensing wheels 51 correspond to each other. A pushing end 42 is disposed between the two dispensing wheels 51. In use, the push rod 43 pushes the pushing plate 41, transporting the paper shafts 2 on the pushing plate 41 to the dispensing wheels 51. Each paper shaft 2 is secured in one of the two parallel slots 52 of the two dispensing wheels 51. The dispensing wheels 51 rotate (…). Figure 1 The middle distribution wheel rotates counterclockwise, transporting several paper rolls 2, which are stuck in the slots 52, to the moving wheel assembly 6 for polishing. The distribution wheel 51 of this utility model is connected to a drive device to drive the distribution wheel 51 to rotate. The drive device can be a drive motor.

[0028] Furthermore, the rotating wheel assembly 6 is disposed between the two distribution wheels 51. The rotating wheel assembly 6 includes a rotatable rotating wheel 61 and a rotating wheel rubber 62 disposed on the outer periphery of the rotating wheel 61. Two rotating wheel rings 63 are disposed on the outer periphery of the rotating wheel rubber 62. The rotating wheel rings 63 are semi-circular in shape. The two rotating wheel rings 63 are respectively disposed on the upper and lower sides of the rotating wheel rubber 62. A gap is provided between the rotating wheel rings 63 and the rotating wheel rubber 62 to allow the paper shaft 2 to pass through. The outer periphery of the rotating wheel rings 63 is also provided with rotating wheel rubber. A rotating wheel ring pressure plate 64 is disposed on the rotating wheel rubber of the rotating wheel rings 63 to press down on the rotating wheel rings 63. The rotating wheel ring pressure plate 64 is mounted on the frame 1 by a bracket 65. In use, the distribution wheel 51 transports the paper shaft 2 to the moving wheel assembly 6. The moving wheel 61 rotates in the same direction as the distribution wheel 51. When the paper shaft 1 approaches the moving wheel 61, it is drawn into the gap between the moving wheel rubber 62 and the moving wheel ring 63 by the rotation of the moving wheel 61, and several paper shafts are transported sequentially to the bottom of the grinding device 7 for grinding. The moving wheel rubber 62 on the moving wheel 61 can increase the friction, making it easier to move the paper shaft 2 from the slot 52 of the distribution wheel 51 to the moving wheel assembly 6. The moving wheel 61 of this utility model is connected to a driving device to drive the moving wheel 61 to rotate. The driving device can be a drive motor.

[0029] Furthermore, the polishing device 7 includes several polishing wheels (not shown) disposed on both sides of the moving wheel assembly 6 for polishing the ends of the paper drawer 2. In this invention, the length of the paper shaft 2 is greater than the width of the moving wheel 61, and both ends of the paper shaft 2 can extend beyond the sides of the moving wheel 61, facilitating the polishing device 7 to polish the ends of the paper shaft 2. Each polishing wheel is connected to a motor 72 that drives the polishing wheel to rotate at high speed; the motor 72 is mounted on the adjusting device 8. The polishing wheels can sharpen the ends of the paper shaft, and their angle can be adjusted using the adjusting device 8 according to the degree of sharpening of the paper shaft 2.

[0030] Furthermore, the adjustment device 8 includes a Z-axis adjustment assembly 81, an R-axis adjustment assembly 82, and an X-axis adjustment assembly 83.

[0031] The Z-axis adjustment assembly 81 includes a Z-axis adjusting screw 811 and a clamp 812 connected to the motor 72. The clamp 812 is connected to the Z-axis adjusting screw nut (not shown) of the Z-axis adjusting screw 811. The Z-axis adjusting screw shaft 8112 of the Z-axis adjusting screw 811 is rotatably mounted on the support base 814. In use, rotating the Z-axis adjusting screw shaft 8112 causes the Z-axis adjusting screw nut to move up and down, thereby causing the clamp 812 to drive the motor 72 to move, thus adjusting the position of the grinding wheel. The position of the motor 72 on the clamp 812 can also be finely adjusted.

[0032] The R-axis adjustment assembly 82 includes an R-axis adjusting screw 821 and an R-axis adjusting support 822 hinged to a support base 814. The support base 814 is hinged to the R-axis adjusting screw nut 8211 of the R-axis adjusting screw 821. The R-axis adjusting screw shaft 8212 of the R-axis adjusting screw 821 is rotatably mounted on a shaft seat 823, which is hinged to the R-axis adjusting screw support 824. In use, by turning the R-axis adjusting screw 821, the angle of the support base 814 can be adjusted significantly. By rotating the R-axis adjusting screw shaft 8212 of the R-axis adjusting screw 821, the R-axis adjusting screw nut 8211 can be moved, causing the support base 814 to move for small-angle fine adjustments, thereby achieving position adjustment of the grinding wheel 71.

[0033] The X-axis adjustment assembly 83 includes an X-axis adjusting screw 831 and a platform 832 inclinedly mounted on the frame 1. A base 833 and an X-axis adjusting screw support 834 are mounted on the platform 832. The X-axis adjusting screw 831 is mounted on the X-axis adjusting screw support 834. A sliding groove 8321 is provided on the platform 832, and the base 833 and platform 832 are slidably connected via the sliding groove 8321. An R-axis adjusting support 822 and an R-axis adjusting screw support 823 are mounted on the base 832. The end of the screw shaft of the X-axis adjusting screw 831 can be aligned with the R-axis adjusting screw support 823. In use, rotating the X-axis adjusting screw 831 causes the end of its screw shaft to push the R-axis adjusting screw support 823, which in turn moves the base 833 on the platform 832, thus adjusting the position of the grinding wheel 71.

[0034] The dust collection device 9 includes a dust collection box 91 located below the grinding wheel. Several dust collection boxes 91 can be provided. The bottom of the dust collection box 91 is provided with a dust collection port 92. The dust collection port 92 can be equipped with a fan and pipe (not shown) for dust collection. The dust collection box 91 is located on the frame 1. In use, the dust collection box 91 can be used to suck the debris from the grinding wheel 71 grinding the paper drawer 2 into the dust collection box to prevent pollution of the production environment.

[0035] The working principle of this utility model is as follows: Several paper shafts 2 are stacked and placed between the first baffle 32 and the second baffle 33. The ends of the paper shafts 2 are aligned by the positioning plate 31. The paper puller 2 falls into the pusher plate 41 below through the discharge port 34. The pusher 43 is driven by the drive motor to push the pusher plate 41 back and forth to transport the paper shafts 2 to the distribution wheel 51. Each paper shaft 2 will be stuck in the two parallel slots 52 of the two distribution wheels 51. By rotating the distribution wheel 51, the paper shafts 2 stuck in the slots 52 are transported to the moving wheel assembly device 6. When the paper shaft 1 is close to the moving wheel 61, it will be driven by the rotation of the moving wheel 61 and rolled into the gap between the moving wheel rubber 62 and the moving wheel ring 63. The paper shafts 2 are transported to the bottom of the grinding device 7 in sequence. The paper shafts 2 are ground by pre-adjusting the angle position of the grinding wheel. The ground paper shafts 2 are transported to the next station by the rotation of the moving wheel 61 to complete the material collection.
