Description

Technical Field

[0001] The utility model belongs to the field of plate material screening, in particular to a plate material screening device. Background Art

[0002] When factories make furniture, sheet materials are an essential raw material. When using sheet materials to customize and produce different furniture, the sheet materials are often first cut into several relatively large and small sheets. The cut sheets are unloaded one by one and in an orderly manner onto the unloading mechanism, and then inspected by the inspection mechanism, such as visual inspection to check whether the display surface of the sheet is complete. The inspected sheets are transported to the next station through the screening device, and if the sheets that do not meet the requirements are detected, they can be selected by the screening device.

[0003] When the plates do not meet the requirements, most of the existing screening devices use power sources to directly remove the plates that do not meet the requirements. Although this can also screen the plates that do not meet the requirements, this screening method is too simple and easily damages the plates that do not meet the requirements, resulting in poor screening effects. Utility Model Content

[0004] In view of the above problems, the purpose of the present invention is to provide a plate screening device, aiming to solve the problem that the screening method of the existing plate screening device is too simple and the screening effect is poor.

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0015] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0016] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.

[0017] Combination Figure 1-3 As shown, the screening device includes a chassis 1, and the chassis 1 is provided with a pair of left and right side panels, such as Figure 1As shown, the left side plate is marked as 2.1 and the right side plate is marked as 2.2, wherein the left side plate 2.1 can move left and right, and the right side plate 2.2 is fixedly installed, and a group of rollers 3 are rotatably provided on the inner side of each side plate, and a carrier plate 4 is provided in the chassis 1, and a pair of screening racks 5 are provided on the carrier plate 4, wherein the left screening rack is slidably installed, and the right screening rack is fixedly installed, each screening rack 5 passes through the top of the side plate on the same side, and the screening bars 6 in the screening rack 5 are staggered with the rollers on the same side, and each screening bar 6 is formed with a carrier block 7 along the length direction, and a lifting cylinder 8 for driving the carrier plate 4 to move up and down is also provided in the chassis 1, and a driving mechanism for driving all rollers 3 to rotate simultaneously is also provided on the chassis 1.

[0018] In this embodiment, a feeding mechanism is provided at the front end of the device, a detection mechanism is provided on the feeding mechanism, and a conveying platform is provided at the rear end. When a factory makes furniture, sheet materials are an indispensable raw material. When using sheet materials to customize the production of different furniture, the sheet materials are often first cut into several relatively large and small plates. The cut plates are fed one by one and orderly onto the feeding mechanism, and are inspected by the detection mechanism, such as by visual inspection to detect whether the display surface of the plate is complete. The inspected plates are conveyed to the conveying platform through this device. Of course, if the detection mechanism detects plates that do not meet the requirements, they can be selected by this screening device. The above-mentioned feeding mechanism, detection mechanism, and conveying platform are not the focus of this device, so they will not be described here.

[0019] Slide wheels 9 are rotatably provided at both ends of the side plates. The slide wheels are provided to facilitate the feeding and discharging of the plates. When the device is used to screen the plates, the spacing between the left and right side plates can be adjusted according to the size of the plates to adapt to plates of different sizes.

[0020] When the plate slides into the device through the sliding wheel at the front end, two sets of rollers support the current plate, and the two sets of rollers rotate simultaneously to transport the current plate to the conveying table. If the current plate does not meet the requirements, the lifting cylinder will drive the carrier plate to move up one station, and the screening rack will also move up one station synchronously. The current plate will be lifted up by the carrier block on the same layer, and the plate will be separated from the rollers. If the next plate does not meet the requirements, the same lifting cylinder will continue to drive the carrier plate to move up one station, and the next plate will also be lifted up.

[0021] As a preferred structure, Figure 2-3The chassis 1 is also provided with a fixed plate 10, a pair of threaded rods 11 are rotatably provided between the fixed plate 10 and the right side plate 2.2, the left side plate 2.1 is installed on the threaded rod 11 through a pair of threaded sleeves 12, a pair of linkage rods 13 are rotatably provided on the outer side of the fixed plate 10 on the chassis 1, a pair of driven bevel gears 14 are provided on the linkage rods 13, the left ends of the threaded rods 11 are provided with active bevel gears 15, and the active bevel gears 15 are meshed and installed with the corresponding driven bevel gears 14, and a crank shaft 23 is provided at the right end of one of the threaded rods 11, and the crank shaft 23 passes through the right side plate and is rotatably installed on the chassis 1.

[0022] In this device, the left side plate can be moved left and right to adapt to plates of different sizes. When the distance between the left and right side plates needs to be adjusted, the end of the crankshaft is a square column, the square sleeve is inserted into the crankshaft, and the square sleeve is rotated, the threaded rod rotates, and under the linkage of the active bevel gear and the driven bevel gear, the other threaded rod rotates synchronously, and at this time, the left side plate is moved along the length direction of the threaded rod through the threaded sleeve to achieve the purpose of adjusting the distance between the two side plates.

[0023] In this structure, the shaft of the roller 3 passes through the side plate and is provided with a slave sprocket 16. The driving mechanism includes a hexagonal shaft 17 rotatably installed between the fixed plate 10 and the right side plate 2.2. A pair of hexagonal sleeves 18 are sleeved on the hexagonal shaft 17. The hexagonal sleeves 18 are rotatably installed on the side plate on the same side. A main sprocket 19 is provided on the outer side of each hexagonal sleeve 18 on the side plate. The main sprocket 19 and all the slave sprockets 16 on the same side are jointly sleeved with a matching chain (not shown in the figure). The chassis is also provided with a driving motor 20 for driving the hexagonal shaft 17 to rotate.

[0024] When the device is used to screen plates, when the plates enter the device, two groups of rollers support the plates, and the driving mechanism drives all the rollers to rotate simultaneously to transport the current plates to the conveying platform.

[0025] Specifically, the driving motor drives the hexagonal shaft to rotate, and the two main sprockets rotate synchronously through the hexagonal sleeves. Under the linkage of the chain, all the rollers rotate synchronously. The design structure of the hexagonal shaft and the hexagonal sleeve is that when the left side plate moves, the left hexagonal sleeve will slide on the hexagonal shaft. In this way, the hexagonal sleeve can rotate synchronously with the hexagonal shaft, and can also slide along the length direction of the hexagonal shaft driven by the left side plate. The entire design structure is quite ingenious.

[0026] In addition, each side plate is provided with adjustment grooves (blocked in the figure) on both sides of the main sprocket 19, and a friction wheel 22 is provided in the adjustment groove. In this structure, friction wheels are rotatably provided on both sides of the main sprocket, and the tightness of the chain is adjusted by adjusting the position of the friction wheel. In the embodiment, the end face of the friction wheel is provided with a locking bolt (not shown in the figure) for mounting the friction wheel on the adjustment groove. When the installation position of the friction wheel needs to be adjusted, the locking bolt is first loosened, and the friction wheel can be adjusted along the length direction of the adjustment groove. After the adjustment is in place, the locking bolt is tightened.

[0027] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
