Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Examples

As shown in fig. 1, the embodiment of the utility model provides a flatness detecting device for plastic sheets, which comprises a base 1, a first motor 4, a second motor 11, a detector 15 and a driving cylinder 18, wherein the top of the base 1 is fixedly connected with a first fixing plate 2, the top of the first fixing plate 2 is fixedly connected with a second fixing plate 3, the first motor 4 is fixedly connected with the top of the second fixing plate 3, the driving end of the first motor 4 is fixedly connected with a driving plate 5 through a rotating shaft, the bottom of one end of the driving plate 5 far away from the first motor 4 is fixedly connected with a driving rod 6, a movable plate 7 is arranged below the second fixing plate 3, a slot 8 is arranged at the top of the movable plate 7, the driving rod 6 is in sliding clamping connection with the inside of the slot 8, the bottom of the second fixing plate 3 is symmetrically and fixedly connected with two clamping plates 9, the two clamping plates 9 are respectively contacted with two side walls of the movable plate 7, the bottom of the second fixed plate 3 is symmetrically and fixedly connected with two connecting plates 10, two clamping plates 9 are positioned between the two connecting plates 10, a second motor 11 is fixedly connected to the side wall of one connecting plate 10 far away from the clamping plates 9, a driving end of the second motor 11 is fixedly connected with a screw rod 12, the screw rod 12 is rotationally connected between the two connecting plates 10, the outer surface of the screw rod 12 is in threaded connection with two limiting plates 13, a mounting plate 14 is arranged above the base 1, sliding grooves are formed in two side walls of the mounting plate 14, the sliding grooves of the two side walls of the mounting plate 14 are respectively and slidably clamped with the two limiting plates 13, a detector 15 is arranged on the front surface of the mounting plate 14, the top of the mounting plate 14 is fixedly connected with a limiting rod 16, a limiting groove 17 is formed in the bottom of the movable plate 7, the limiting rod 16 is slidably clamped inside the limiting groove 17, a driving cylinder 18 is fixedly connected to the top of the base 1, the movable end of the driving cylinder 18 is fixedly connected with a placing plate 19.

The upper and lower surfaces of the movable plate 7 are in close contact with the bottom of the driving plate 5 and the top of the mounting plate 14, respectively. The main purpose of this design is to ensure that the movable plate 7 remains at a constant height during movement, avoiding its sloshing or shifting due to uneven stress or minor errors during movement. By the close contact design, the movable plate 7 can stably move along a predetermined path when receiving the driving force of the driving lever 6 without causing a height change due to uneven stress. Such stability is critical to ensure that the detector 15 is able to accurately and stably detect the flatness of the plastic sheet.

The placement plate 19 is designed to be located below the detector 15. This arrangement enables the detector 15 to directly detect the plastic sheet placed on the placement plate 19 without additional adjustment or movement. The design simplifies the detection flow and improves the detection efficiency. Meanwhile, the accuracy and precision of detection are improved due to the fact that the distance between the detector 15 and the plastic sheet is relatively short.

The two limiting plates 13 are connected through a fixing rod, and the screw rod 12 is positioned right in front of the fixing rod. The design not only enhances the structural stability between the limiting plates 13, but also ensures that the screw rod 12 can be kept stable when the limiting plates 13 are driven to move. The fixing rod penetrates through the two limiting plates 13, so that the connection strength between the limiting plates 13 is further enhanced. The design ensures that the limiting plate 13 can be kept stable in the moving process, and detection errors caused by shaking or deflection are avoided.

Working principle when using the flatness detecting device of plastic sheet, the operator places the plastic sheet to be detected on the placing plate 19. By the action of the driving cylinder 18, the placement plate 19 and the plastic sheet thereon are pushed upward. When the plastic sheet is raised to a certain position, it will come into contact with the detector 15 on the mounting plate 14, ready for detection. The first motor 4 is started to drive the driving rod 6 at the bottom of the driving plate 5 to perform circumferential rotation. The driving rod 6 is in sliding clamping connection with a slot 8 at the top of the movable plate 7, and the movable plate 7 is limited by two clamping plates 9. Thus, the rotation of the driving lever 6 is converted into a longitudinal linear motion of the movable plate 7 along the side wall of the clamping plate 9. Because the limit rod 16 at the top of the mounting plate 14 is clamped in the limit groove 17 at the bottom of the movable plate 7, the movement of the movable plate 7 can drive the mounting plate 14 to move together. The mounting plate 14 is in sliding clamping connection with the sliding grooves on the two side walls of the mounting plate through the two limiting plates 13, so that stable longitudinal movement of the mounting plate is ensured. Thereby, the detector 15 of the front surface of the mounting plate 14 also realizes a longitudinal rectilinear motion. The second motor 11 is started to drive the screw 12 to rotate. The rotation of the screw rod 12 drives the two limiting plates 13 to perform transverse linear motion. Because the limiting plate 13 is in sliding clamping connection with the sliding groove of the mounting plate 14, the limiting plate and the sliding groove can drive the mounting plate 14 and the detector 15 on the mounting plate to transversely move together. By means of the above-described adjustment of the longitudinal and transverse movements, the detector 15 can be changed in its position as desired. This enables the detector 15 to perform a full detection of the flatness of the plastic sheet on the placement plate 19.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
