Description

Technical Field

[0001] The present application relates to the field of PVC sheet processing, and in particular to a PVC sheet trimming device. Background Art

[0002] At present, when processing PVC boards, the back-end process includes the process of trimming the boards. Currently, the trimming is performed automatically by a trimming machine.

[0003] Existing trimming machines usually include a dust cover and a cutting blade rotatably arranged in the dust cover. In order to collect scraps, a suction component is usually arranged on the dust cover to collect the cut scraps by using negative pressure. However, it is found during use that the scraps on the top are usually sucked away by the suction component, but the debris splashed below when the cutting blade cuts the plate cannot be cleaned up, resulting in accumulation on the machine, affecting the workshop environment. It is usually necessary to manually clean the debris under the machine. In addition, the spacing under the cover is difficult to design. At present, when the spacing under the cover is small, it is easy to interfere with the plate during the cutting process. When the spacing under the cover is large, more debris splashes and the scrap collection efficiency is poor.

[0004] In view of this, those skilled in the art need to improve the existing material unloading rack to overcome the above-mentioned defects. Utility Model Content

[0005] The main purpose of the present application is to provide a PVC sheet trimming device, in which an elastic support component, a material blocking component and a blocking cover are arranged between the shield and the pad, thereby greatly preventing the splashing of scraps during the trimming process, and a second dust suction component is arranged to facilitate the collection of debris below.

[0007] A further improvement is that the dust blocking assembly includes a brush holder fixedly arranged on the protective cover and a brush fixedly arranged on the brush holder.

[0008] As a further improvement, the elastic support assembly comprises an elastic skeleton fixedly connected to the shield and in a Z shape, and a flexible support membrane fixedly arranged on both sides of the elastic skeleton.

[0009] A further improvement is that the flexible support membrane is a silicone membrane.

[0010] As a further improvement, the elastic support assembly further comprises a sealing pad block fixedly arranged on the lower surface of the elastic skeleton, and the sealing pad block is a rubber block.

[0011] As a further improvement, the first driving mechanism is a driving motor, the motor body of the driving motor is fixedly arranged on the shield, and the motor shaft of the driving motor is connected to the central axis of the cutting blade.

[0025] like Figure 1-Figure 2 As shown, a PVC sheet trimming device comprises a frame, a trimming head vertically slidably arranged on the frame, and a pad 2 arranged below the trimming head, the trimming head comprises a shield 1, a cutting blade 3 rotatably arranged in the shield 1, a first driving mechanism arranged on the shield 1 and driving the cutting blade 3 to rotate, and a first dust suction component connected to the inner cavity of the shield 1, a second driving mechanism driving the trimming head to slide is arranged between the trimming head and the frame, an opening 7 matching the cutting blade 3 is opened on the pad 2, a collecting cover 6 is arranged below the pad 2, the opening 7 is connected to the inner cavity of the collecting cover 6, the collecting cover 6 is connected to the second dust suction component, an elastic support component and a dust blocking component are respectively arranged between the pad 2 and the shield 1, the elastic support component and the dust blocking component are respectively located on both sides of the cutting blade 3, and also includes a blocking cover fixedly arranged on both sides of the shield 1.

[0026] Working process: when trimming, the second driving mechanism drives the trimming head to move downward. When trimming, the plate moves above the pad 2, and the cutting blade 3 is aligned with the opening 7. When trimming, the first driving mechanism drives the cutting blade 3 to rotate to cut off the scraps of the plate from the main body of the plate. In this process, most of the waste cut is collected by the first dust suction component, and a small amount of debris below falls into the collection cover 6 through the opening 7 and is collected by the second dust suction component. The splashes are blocked by the baffles at both ends, the elastic support components on both sides and the dust blocking components to avoid affecting the ground under the machine, maintaining a good environment in the workshop, especially using a Z-shaped elastic skeleton 8, which makes soft contact with the plate and will not affect the plate. Moreover, it has a certain rigidity and is not easy to deviate, so that it maintains a good sealing effect with the plate, avoiding splashes from entering the upper surface of the plate and affecting its subsequent processes. It should be noted that the procedure is a material receiving process, that is, the cut plates are stacked by negative pressure suction cups. If there are more debris on the surface of the plate, the effect of negative pressure adsorption is affected.

[0027] Preferably, in this embodiment, the dust blocking assembly includes a brush holder 9 fixedly mounted on the protective cover 1 and a brush 10 fixedly mounted on the brush holder 9. The brush 10 is located on the outside without a plate underneath and is in contact with the surface of the pad 2. It only needs to ensure that most splashing objects do not splash and does not need to be completely sealed.

[0028] Preferably, in the present embodiment, the elastic support component includes an elastic skeleton 8 fixedly connected to the protective cover 1 and in a Z shape, and a flexible support membrane fixedly arranged on the inner and outer sides of the elastic skeleton 8 respectively. In order to maintain a good deformation effect, the flexible support membrane is a silicone membrane. In order to form a good contact with the surface of the plate, the elastic support component also includes a sealing pad 11 fixedly arranged on the lower surface of the elastic skeleton 8, and the sealing pad 11 is a rubber block.

[0029] In this embodiment, preferably, the first driving mechanism is a driving motor, the motor body of the driving motor is fixedly disposed on the shield 1 , and the motor shaft of the driving motor is connected to the central axis of the cutting blade 3 .

[0030] Preferably in this embodiment, the first dust suction component includes a first dust suction pipe 4 and a first vacuum pump connected to the first dust suction pipe 4 , and the second dust suction component includes a second dust suction pipe 5 and a second vacuum pump connected to the second dust suction pipe 5 .

[0031] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
