Description

Technical Field

[0001] The utility model relates to the technical field of plate processing, in particular to a 180-degree turning mechanism for a plate. Background Art

[0002] Sheet material is a material widely used in fields such as construction, manufacturing and decoration. It is usually a thin and flat sheet material made of metal, plastic, wood or composite materials. The thickness of the sheet can range from a few millimeters to tens of millimeters. Its length and width also vary greatly and can be cut according to specific needs. Sheets have many types and uses due to their different materials and characteristics. For example, metal sheets are often used to manufacture mechanical parts, vehicle shells, building structures, etc.; plastic sheets are often used to make furniture, decorative materials, billboards, etc.; wood sheets are often used in furniture manufacturing, building decoration, handicraft production, etc.

[0003] At present, in the processing of plates, it is often necessary to perform processing operations such as grinding on both sides of the plates. Therefore, after processing one side, it is necessary to use a flipping mechanism to flip the plates. However, after the existing flipping mechanism flips the plates, the plates may be in a tilted state, which is not convenient for processing. Therefore, the plates need to be manually straightened, which not only reduces work efficiency, but also increases production time costs. Utility Model Content

[0004] The utility model aims to provide a 180-degree turning mechanism for a plate which can adjust the position of the plate after the plate is turned over.

[0005] To achieve the above-mentioned purpose, the technical solution of the utility model is as follows.

[0006] A 180-degree flipping mechanism for plates comprises a frame, a flap frame is arranged on the upper side of the frame, one side of the flap frame is rotatably connected to the frame through two first rotating shafts, first hydraulic cylinders are rotatably installed on both sides of the frame and at one end close to the first rotating shaft, the ends of the telescopic ends of the two first hydraulic cylinders are respectively rotatably connected to both sides of the flap frame and at one end away from the first rotating shaft, a second hydraulic cylinder is rotatably connected to the upper side of the frame and at one end away from the first rotating shaft, a connecting plate is arranged on the lower side of the flap frame and at one end close to the first rotating shaft, and the ends of the telescopic ends of the second hydraulic cylinder are rotatably connected to the connecting plate. Four vacuum suction cups are installed on the flap frame along its length direction, four square sponge suction cups are respectively installed on both sides of the four vacuum suction cups on the flap frame, and a straightening mechanism capable of straightening the position of the plate is arranged on both sides of the flap frame. The straightening mechanism includes a rectangular frame rotatably mounted on the flap frame via a second rotating shaft, six rollers are rotatably mounted inside the rectangular frame, a third hydraulic cylinder is mounted on the surface of the flap frame, the end of the telescopic end of the third hydraulic cylinder is rotatably connected to a side of the rectangular frame away from the second rotating shaft, and a block is mounted on the upper surface of the flap frame.

[0007] It can be seen that through the setting of two first hydraulic cylinders and one second hydraulic cylinder, the flip frame can be driven to flip 180 degrees, and the plate can be adsorbed and fixed by the vacuum suction cup and the square sponge suction cup. Then the flip frame is reset and returns to the upper side of the frame to complete the operation of flipping the plate. After the plate is flipped over, the fixation of the plate by the vacuum suction cup and the square sponge suction cup is cancelled, and then the rectangular frame is lifted up by the third hydraulic cylinder to make the rectangular frame tilt toward one side of the block around the second rotating axis. Therefore, the plate can slide along the roller until it abuts against the block, thereby achieving the purpose of straightening the plate, reducing manual operation, improving work efficiency, and reducing production time costs.

[0008] Furthermore, two fourth hydraulic cylinders are installed on the frame, and push rods are installed at the ends of the telescopic ends of the two fourth hydraulic cylinders. Friction rings are installed on the outer surfaces of the two first rotating shaft ends, and the push rods are arranged directly below the friction rings.

[0009] At the end of the flipping process of the flipping frame, the fourth hydraulic cylinder is started to drive the push rod to push up and press against the friction ring. Due to the large friction force generated, the first rotating shaft can be decelerated, so that the flipping frame can drive the vacuum suction cup and the square sponge suction cup to adsorb the plate at a slower speed, and reset to the upper side of the frame at a slower speed, thereby reducing the impact on the plate and avoiding damage to the plate.

[0010] Furthermore, a vacuum pump is installed on the frame, a diversion pipe is installed on the lower side of the flap frame, and the vacuum pump is connected to the diversion pipe through an air pipe. Twelve joints are arranged on the surface of the diversion pipe, and the twelve joints are respectively connected to four vacuum suction cups and eight square sponge suction cups through air pipes.

[0011] The vacuum pump can provide air source for the vacuum suction cup and the square sponge suction cup to meet their adsorption function on the plate.

[0012] Furthermore, a position monitoring encoder is installed on the frame, and the position monitoring encoder corresponds to the first rotating shaft.

[0013] By setting a position monitoring encoder, the flipping position of the flip rack can be digitized and detected, improving the safe production working environment.

[0014] Furthermore, four groups of diagonal braces are installed inside the frame, and each group of diagonal braces consists of two diagonal braces arranged crosswise with each other.

[0015] By setting up four sets of diagonal braces, the support strength of the frame can be improved, so that the mechanism can turn over a maximum of 2000kg of plate.

[0016] Furthermore, a rubber pad is provided on one side of the stopper facing the rectangular frame.

[0017] By setting the rubber pad, when the plate contacts the rubber pad, the rubber pad can play a role of buffering and protection to prevent the plate from being damaged. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The utility model is described in detail below with reference to the accompanying drawings.

[0025] like Figure 1-5As shown, a 180-degree flipping mechanism for a plate includes a frame 100, a flap frame 101 is arranged on the upper side of the frame 100, one side of the flap frame 101 is rotatably connected to the frame 100 through two first rotating shafts 102, first hydraulic cylinders 103 are rotatably installed on both sides of the frame 100 and one end close to the first rotating shaft 102, the ends of the telescopic ends of the two first hydraulic cylinders 103 are respectively rotatably connected to both sides of the flap frame 101 and one end away from the first rotating shaft 102, a second hydraulic cylinder 104 is rotatably connected to the upper side of the frame 100 and one end away from the first rotating shaft 102, a connecting plate 105 is installed on the lower side of the flap frame 101 and one end close to the first rotating shaft 102, and the end of the telescopic end of the second hydraulic cylinder 104 is rotatably connected to the connecting plate 105. Four vacuum suction cups 106 are installed on the flip frame 101 along its length direction, and four square sponge suction cups 107 are installed on both sides of the four vacuum suction cups 106 on the flip frame 101. Both sides of the flip frame 101 are provided with a straightening mechanism 200 capable of straightening the position of the plate. The straightening mechanism 200 includes a rectangular frame 202 rotatably installed on the flip frame 101 through a second rotating shaft 201, and six rollers 203 are rotatably installed inside the rectangular frame 202. A third hydraulic cylinder 204 is installed on the surface of the flip frame 101, and the end of the telescopic end of the third hydraulic cylinder 204 is rotatably connected to the side of the rectangular frame 202 away from the second rotating shaft 201, and a stopper 205 is installed on the upper surface of the flip frame 101.

[0026] When in use, the two first hydraulic cylinders 103 can be started, and the telescopic ends of the two first hydraulic cylinders 103 drive the flip frame 101 to rotate around the first rotating shaft 102, and when the flip frame 101 flips to 80 degrees or minus 80 degrees, the second hydraulic cylinder 104 provides power assistance, so that the flip frame 101 can complete the 180-degree flip operation, and then the vacuum suction cup 106 and the square sponge suction cup 107 are used to adsorb and fix the plate. Due to the combined use of the vacuum suction cup 106 and the square sponge suction cup 107, plates of different materials can be adsorbed, and then the flip frame 101 flips 180 degrees to reset and return to the upper side of the frame 100. The operation of turning over the plate can be completed. Since the position of the plate may be in an inclined state at this time, and the inclination angle of each plate is different, which will affect the machine or manual processing of the plate, the vacuum suction cup 106 and the square sponge suction cup 107 are cancelled to fix the plate after the plate is turned over, and then the third hydraulic cylinder 204 is started. The telescopic end of the third hydraulic cylinder 204 lifts the rectangular frame 202, so that the rectangular frame 202 tilts around the second rotating shaft 201 to one side of the stop block 205, so that the plate can slide along the roller 203 until it abuts against the stop block 205, thereby achieving the purpose of straightening the plate, reducing manual operations, improving work efficiency, and reducing production time costs.

[0027] Specifically, two fourth hydraulic cylinders 300 are installed on the frame 100, and push rods 301 are installed at the ends of the telescopic ends of the two fourth hydraulic cylinders 300. Friction rings 302 are installed on the outer surfaces of the ends of the two first rotating shafts 102, and the push rods 301 are arranged directly below the friction rings 302. At the end of the flipping process of the flip frame 101, the fourth hydraulic cylinders 300 are started to drive the push rods 301 to push up and press against the friction rings 302. Due to the large friction force generated, the first rotating shaft 102 can be decelerated, so that the flip frame 101 can drive the vacuum suction cup 106 and the square sponge suction cup 107 to adsorb the plate at a slower speed, and reset to the upper side of the frame 100 at a slower speed, thereby reducing the impact on the plate and avoiding damage to the plate.

[0028] Specifically, a vacuum pump 400 is installed on the frame 100, a diverter pipe 401 is installed on the lower side of the flip frame 101, and the vacuum pump 400 is connected to the diverter pipe 401 through an air pipe. Twelve joints 402 are arranged on the surface of the diverter pipe 401, and the twelve joints 402 are respectively connected to four vacuum suction cups 106 and eight square sponge suction cups 107 through air pipes. The vacuum pump 400 can provide an air source for the vacuum suction cups 106 and the square sponge suction cups 107 to meet their adsorption function for the plate.

[0029] Specifically, a position monitoring encoder 500 is installed on the frame 100, and the position monitoring encoder 500 corresponds to the first rotating shaft 102. By setting the position monitoring encoder 500, the flipping position of the flip frame 101 can be digitized and detected, thereby improving the safe production working environment.

[0030] Specifically, four groups of diagonal braces 600 are installed inside the frame 100, and each group of diagonal braces 600 is composed of two diagonal braces 600 arranged crosswise with each other. By setting up four groups of diagonal braces 600, the supporting strength of the frame 100 can be improved, so that the mechanism can turn over a maximum of 2000kg of plate.

[0031] Specifically, a rubber pad 700 is disposed on one side of the stopper 205 facing the rectangular frame 202. Through the provision of the rubber pad 700, when the plate contacts the rubber pad 700, the rubber pad 700 can play a role of buffering and protection to prevent the plate from being damaged.
