Description

Technical Field

[0001] The utility model relates to the technical field of polishing imitation wood grain railings, and more specifically, to a polishing device for imitation wood grain railings. Background Art

[0002] Wood grain guardrail is also a kind of guardrail with the most decorative effect. The inner cavity of the guardrail is reinforced with galvanized steel lining or aluminum alloy. It has sufficient strength and impact resistance, and is corrosion-resistant, tough, anti-static, non-fading, non-cracking, and non-brittle. When producing imitation wood grain railings, it is necessary to grind their surface. For this purpose, a grinding device is proposed for grinding imitation wood grain railings.

[0003] After searching, for example, a grinding device for the production of imitation wood grain railings with publication number CN214722850U is found. The wood to be grinded is inserted into the clamping device, the rotating device is started, and the second motor of the rotating device drives the wood to rotate. Then the first motor on the left side of the grinding device is started, and the first motor drives the grinding wheel to rotate through the first belt. At this time, the operating screw is rotated, so that the screw drives the grinding device to move up and down to grind the outside of the wood. At the same time, when encountering a place that needs to be polished separately, it is only necessary to stop rotating the screw and continue grinding.

[0004] However, when the above scheme is used, the imitation wood grain railing is clamped by a plywood, and the imitation wood grain railing is then polished using a polishing wheel. Since the polishing wheel is located in the center of the above scheme, it is difficult to polish the upper and lower ends of the imitation wood grain railing. Moreover, the above scheme can only polish imitation wood grain railings of a single length, and it is difficult to polish imitation wood grain railings of a longer length, and its scope of application is limited. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a wood-grain imitation railing grinding device, and the technical problem to be solved is: it is difficult to grind both ends of the wood-grain imitation railing, and it can only be used to grind wood-grain imitation railings of a single length, and the scope of application is small.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a wood-grain imitation railing polishing device, comprising a processing table:

[0007] A chip removal groove is provided on the inner side of the processing table, and a rotating cylinder is movably provided on the upper end of the processing table.

[0009] The railing transmission device includes a support platform, which is fixedly arranged at the upper end of the processing platform, and a crawler motor is fixedly arranged at the lower end of the support platform through a bracket;

[0010] The upper end of the processing table is provided with a rotating grinding device capable of grinding the surface of the imitation wood grain railing, which is used to drive the rotating cylinder to rotate so that the two grinding plates grind the surface of the imitation wood grain railing.

[0011] In a preferred embodiment, a movable platform is movably provided on the upper end of the support platform, the support platform and the movable platform are symmetrical to each other, and two conveying wheels are movably provided on the inner side of the support platform and the movable platform respectively.

[0012] In a preferred embodiment, a transmission disc is fixedly provided on one side of each of the two conveying wheels at the upper end of the support platform, and the output end of the support platform is connected to the transmission disc via a crawler belt transmission.

[0013] In a preferred embodiment, two fixed seats are fixed on both sides of the support platform, a limiting slide rod is fixed on the upper end of the fixed seat, two sliding plates are fixed on both sides of the movable platform, the limiting slide rod passes through the inner side of the sliding plate, and a first spring is movably provided between the sliding plate and the upper end protrusion of the limiting slide rod.

[0014] In a preferred embodiment, the rotary grinding device includes two support frames, which are fixedly arranged on the upper ends of the processing table, and the upper ends of the two support frames are respectively fixed with connecting frames.

[0015] In a preferred embodiment, the connecting frame is located on the outer surface of the rotating cylinder, and a plurality of rolling balls are movably provided between the connecting frame and the rotating cylinder. A rotating motor is fixedly provided on one side of one of the support frames, and the output end of the rotating motor passes through the inner sides of the two support frames.

[0017] The technical effects and advantages of this utility model are:

[0018] 1. The utility model uses two support platforms and two moving platforms to clamp the same imitation wood grain railing with eight conveyor wheels. When the crawler motor is running, the conveyor belt drives the two conveyor wheels to rotate, thereby achieving the effect of conveying the imitation wood grain railing. The movable platform is then limited by the limit slide bar, and the first spring tops the sliding plate, thereby squeezing the imitation wood grain railing, making the conveying of the imitation wood grain railing more stable. The whole is suitable for conveying and grinding imitation wood grain railings of different lengths, which expands the scope of application of the utility model.

When the conveying wheel conveys the imitation wood grain railing to between the two grinding plates, the pulling rod is loosened, and the two grinding plates are pressed against the surface of the imitation wood grain railing by using the second spring. The rotating motor is started to drive the rotating gear to rotate, so that the engagement of the rotating gear and the transmission gear can make the rotating cylinder rotate, driving the two grinding plates to grind around the imitation wood grain railing, thereby achieving the effect of rotational grinding as a whole. When the imitation wood grain railing is conveyed by the conveying wheel, the imitation wood grain railing can be polished as a whole, avoiding the problem of difficulty in polishing at both ends.
