DETAILED DESCRIPTION

[0021] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0022] See also Figure 1-6 A technical solution provided by an embodiment of the utility model: the grinder for processing plastic products includes a base 1, an arch frame 5 is provided on the base 1, an arc-shaped guide hole 7 is provided in the arch frame 5, and a plurality of arc-shaped grooves 6 are provided in a circular array on the inner wall of the guide hole 7, a connecting rod 18 is slidably connected in the guide hole 7, the connecting rod 18 can be engaged with any one of the grooves 6, an electric push rod 19 is provided at one end of the connecting rod 18, a grinder body 20 is provided at the output end of the electric push rod 19, a transmission assembly for driving the connecting rod 18 to slide along the guide hole 7 is provided at the other end of the connecting rod 18, and a clamping assembly for clamping plastic products is provided on the base 1.

[0023] As a preferred technical solution, the transmission assembly includes a rotating plate 4, a first motor 2 and a second slider 17. A second slide groove 15 is opened on one side of the rotating plate 4. The second slider 17 is vertically slidably connected in the second slide groove 15. One end of the second slider 17 is fixedly connected to the connecting rod 18. The first motor 2 is fixedly connected to the base 1. The output end of the first motor 2 is fixedly connected to the rotating plate 4. Specifically, the first motor 2 is started to drive the rotating plate 4 to rotate. The rotating plate 4 drives the grinder body 20 to make an arc movement along the guide hole 7 through the second slider 17. The second slide groove 15 and the second slider 17 are arranged to adapt to the change in the sliding radius when the connecting rod 18 slides from one groove 6 to another groove 6.

[0024] As a preferred technical solution, a second spring 16 is provided between the second slider 17 and the bottom wall of the second slide groove 15. Specifically, the elastic force of the second spring 16 can ensure that the second slider 17 is always in sliding contact with the inner wall of the guide hole 7 and the inner wall of each groove 6, thereby preventing the connecting rod 18 from sliding from one groove 6 to another groove 6. In the process of the rotating plate 4 rotating too fast, the connecting rod 18 is caused to break away from the groove 6 and bounce up due to inertia, and collides with the arch frame 5, which will cause damage to the equipment.

[0025] As a preferred technical solution, the clamping assembly includes an articulated seat, in which an articulated shaft 10 is rotatably connected, a connecting plate 9 is sleeved on the articulated shaft 10, a supporting plate 3 is fixedly connected to the top of the connecting plate 9, and two clamping plates 14 are relatively slidably connected on both sides of the supporting plate 3. A second motor 8 is provided on the base 1, and the output end of the second motor 8 is coaxially fixedly connected to the articulated shaft 10. Specifically, starting the second motor 8 can drive the connecting plate 9 to rotate, so that the supporting plate 3 rotates relative to the connecting plate 9, and the inclination angle of the plastic product to be polished can be adjusted, so that the polishing angle is more extensive.

[0026] As a preferred technical solution, two first sliding grooves 11 are horizontally opened in the supporting plate 3, and the first sliders 13 are slidably connected in the two second sliding grooves 15. First springs 12 are provided between the two first sliders 13 and the inner walls of the two first sliding grooves 11, and the two first sliders 13 are fixedly connected with two clamping plates 14 in a one-to-one correspondence. Specifically, the two clamping plates 14 are pulled to place the plastic product to be polished on the supporting plate 3, and the elastic force of the first springs 12 is used to reset the two clamping plates 14 to fix the plastic product to be polished on the supporting plate 3.

[0027] As a preferred technical solution, the corners between two adjacent grooves 6 are rounded. Specifically, when the connecting rod 18 slides from one groove 6 to another groove 6, the rounded corners can make the sliding process smoother without any jamming.

[0028] Working principle: The plastic product processing grinder first fixes the plastic product to be grinded on the supporting plate 3, adjusts the inclination angle of the supporting plate 3 by the second motor 8, starts the first motor 2 to drive the connecting rod 18 to slide along the guide hole 7, and adjusts the inclination angle of the grinder body 20 between 0 and 180 degrees. The adjustment angle has a large adjustment range, and the setting of the groove 6 can more accurately position the grinding angle, thereby improving the grinding effect of the plastic product. The electric push rod 19 is used to facilitate the adjustment of the distance between the plastic product and the grinder body 20, and the grinding effect is better.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
