Description

Technical Field

[0001] The utility model belongs to the technical field of tile turning machines, and in particular relates to a tile turning machine. Background Art

[0002] During the production process, the ceramic tile blank needs to be turned over for double-sided processing. Factories usually use a blank turning machine with a cross-shaped turning frame to turn the blank over. The rotation axis of the cross-shaped turning frame is perpendicular to the conveying direction. When the blank is received, it needs to be rotated 180 degrees to turn the blank over and send it to the next conveying device. When the blank is in a vertical state during the turning process, the center of gravity of the blank is higher than the height of the conveyor belt. The blank may fall to the conveyor belt at the rear end, which is easy to cause unnecessary damage to the blank. Some blank turning machines use a circular turning frame, which uses the double-layer transmission belt in the middle of the circular turning frame to limit the blank, and then the circular turning frame is rotated 180 degrees to realize the turning of the ceramic tile blank. However, in actual production, in order to cooperate with the front and rear end transportation, the diameter of the circular turning frame is usually slightly larger than the width of the front and rear end conveyor belts. The overall circular turning frame is larger, and the ceramic tile blank is turned over together with the double-layer transmission belt during turning, and the required power consumption is also larger.

[0003] Therefore, there is an urgent need for a tile turning machine that can reduce damage to the tile when turning over, has a lower center of gravity and consumes less power. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0027] The present invention will be further described below in conjunction with specific embodiments, but this is not intended to limit the present invention.

[0028] A tile turning machine comprises a base frame 1, on which at least two turning stations are arranged, each of which is adjacently arranged in sequence along the width direction of the base frame, and each of which is equipped with a loading conveyor belt 2 and a unloading conveyor belt 4;

[0029] Each two adjacent blank turning stations are connected by a side-turning mechanism, which includes a side-turning device 3 for turning blanks. The side-turning device includes at least one group of blank turning frames for loading materials and a side-turning drive unit for turning the blank turning frames between two adjacent blank turning stations. At least one of the blank turning stations is a material receiving station, and a material receiving device for receiving the tile blanks on the side-turning device 3 is arranged at the material receiving station; the flipping axis of the blank turning frame is axially parallel to the conveying direction of the loading conveyor belt 2 and the unloading conveyor belt 4.

[0030] like Figure 1 As shown, two turning over stations are arranged on the base frame 1, namely the first station 101 and the second station 102. The loading conveyor belt 2 transports the ceramic tile blank to one of the stations. The receiving device 303 on the other station is in an inclined state of being rotated upward at a certain angle. The side-turning device 3 rotates to rotate the ceramic tile blank on the loading station toward another receiving station. When the ceramic tile blank rotates more than 90°, the ceramic tile blank falls toward the receiving station due to gravity. At this time, the inclined receiving device 303 can receive the ceramic tile blank from both sides of the ceramic tile blank before the ceramic tile blank hits the receiving station, and drives the ceramic tile blank to rotate downward until it is horizontal, so that the ceramic tile blank is slowly turned over to the receiving station, and then transported to the unloading conveyor belt 4, which reduces the turning center of gravity of the ceramic tile blank, reduces the risk of the blank falling, avoids unnecessary damage to the blank, simplifies the overall side-turning mechanism, and reduces the power consumption required for turning.

[0031] In order to adapt to the multiple parallel horizontal conveying on the conveyor belt, the setting direction of two adjacent workstations is perpendicular to the conveying direction, so that the ceramic tile body can be loaded and unloaded at different conveying workstations before and after flipping. In actual operation, the flipping direction can be adjusted according to the actual conveying situation. The first workstation 101 rotates toward the second workstation 102 in the first mode, and the second workstation 102 rotates toward the first workstation 101 in the second mode. The operator can use only the first mode or the second mode, or use the first mode and the second mode alternately.

[0032] As a specific implementation of the structure for realizing the flipping process of the tile blank, the blank flipping frame includes a rotating shaft and a plurality of side flipping plates 305 circumferentially arranged on the rotating shaft. The side flipping driving unit is a flipping motor. One end of the rotating shaft is transmission-connected to the output end of the flipping motor. The rotating shaft is located at the bottom between two adjacent blank flipping stations and the axial direction of the rotating shaft is parallel to the conveying direction. Figure 1 As shown, the rotating shaft is located at the bottom between the first station 101 and the second station 102, so as to reduce the center of gravity of the ceramic tile blank as much as possible during the flipping. During the actual flipping, the rotating shaft drives the multiple side flipping plates to rotate continuously, and the ceramic tile blank on the first station 101 is flipped to the second station 102 continuously. The width of the side flipping plate is smaller than the width of the ceramic tile blank.

[0033] As a specific implementation of the side flap distribution method, the side flap 305 is circumferentially distributed on the rotating shaft in a cross shape. In actual situations, the side flipping can be achieved by modifying the existing blank turning machine with a cross flipping frame.

[0034] In order to prevent the tile blank from tilting and falling toward the receiving station in a vertical state, the angle between two adjacent side flaps 305 is not greater than 60°, which reduces the angle at which the tile blank tilts toward the receiving station. Figure 3 As shown, when the material receiving device 303 fails or fails to reach the tilting state for receiving the material, the front side flip plate 305 receives the tilted ceramic tile body in advance, further avoiding unnecessary damage to the ceramic tile body due to tilting.

[0035] As another specific embodiment of the structure for realizing the flipping process of the tile blank, the flipping frame includes a flipping plate arranged on the flipping station, and the side flipping driving unit is a jacking folding rod 3031 connecting the base frame 1 and the bottom surface of the flipping plate. The side of the flipping plate and the bottom of the jacking folding rod 3031 are both rotatably mounted on the base frame 1, and the jacking folding rod 3031 is provided with a jacking cylinder, such as Figure 1 As shown, the flip plates are a first flip plate 301 located on the first station 101 and a second flip plate 302 located on the second station 102. Both flip plates are rectangular plates. The sides of the rectangular plates are rotatably mounted on the base frame 1. The lifting cylinder is rotatably arranged on the base frame 1 and is rotatably connected to a connecting rod at the top. The lifting cylinder and the connecting rod form a lifting folding rod. The other end of the connecting rod is rotatably connected to the middle part of the rectangular plate. When the lifting cylinder is extended, the rectangular plate rotates along the rotating connection to achieve flipping.

[0036] More specifically, the side edges of the rectangular plate are detachably connected to the base frame 1 through telescopic connectors, such as Figure 4 As shown, the telescopic connecting member is a telescopic pin 307, and the four sides of the rectangular plate are provided with pin holes 306 adapted to the telescopic pin 307. In actual use, the controller controls the telescopic pin 307 to extend into the pin hole 306 to form a rotating connection, and cooperates with the lifting of the lifting cylinder and the lifting folding rod to realize the flipping of the flip plate in four directions.

[0037] In order to facilitate the material receiving device to receive the tile body in time, the rotation direction of the material receiving device 303 is opposite to that of the blank turning rack, that is, the rotation direction of the blank turning rack is from the loading station to another laterally adjacent material receiving station, and the rotation direction of the material receiving device is from another material receiving station to the loading station, so that the material receiving device 303 can receive the tile body before the tile falls.

[0038] In order to facilitate the loading and unloading transportation and flipping of ceramic tile blanks, the width of the turning rack along the conveying direction is smaller than the width of the ceramic tile blanks. The ceramic tile blanks only contact the turning rack in the middle part. The bottom surface of the ceramic tile blanks has areas on both the front and rear sides along the conveying direction that are not in contact with the turning rack. The material receiving device and the loading and unloading conveyor belts achieve material receiving force or transportation acceptance by contacting this area.

[0039] As a specific embodiment of the structure of the material receiving device 303, the material receiving device 303 is a material receiving plate rotatably arranged at the head and tail sides of the workstation, and a tensioning and closing assembly is arranged between the bottom of the material receiving plate and the top of the base frame 1. When the blank turning frame is the first flip plate 301 and the second flip plate 302, the material receiving plate is arranged at the head and tail sides of the first flip plate 301 and the head and tail sides of the second flip plate 302 along the conveying direction; when the blank turning frame is a plurality of side flip plates 305 arranged circumferentially around the rotating shaft, the material receiving plate is arranged at the head and tail sides of the blank turning frame as a whole along the conveying direction. When the material receiving plate is in the state of receiving the material, it is driven by the tensioning and closing assembly to form an angle of not less than 45° with the horizontal plane, so as to facilitate receiving the tilted tile blank. When the tile blank is turned from the first station 101 to the second station 102, the receiving plates at the head and tail of the second station 102 are responsible for receiving the material, and when the tile blank is turned from the second turning plate 302 to the first turning plate 301, the receiving plates at the head and tail of the first station 101 are responsible for receiving the material. The opening and closing assembly is a lifting folding rod or a cross-connecting rod structure or a folding fan type connection structure.

[0040] In order to further reduce the damage caused by the force on the bottom end of the tile blank during the flipping process, a flipping assisting assembly 304 for abutting against one end of the tile blank is provided between two adjacent flipping stations. The flipping assisting assembly 304 is located at the front and rear sides of the side flipping device 3. Figures 1 to 3 As shown, when the first flip plate 301 drives the tile body to rotate toward the second flip plate 302, the tile body is affected by gravity and is likely to slide downward at the beginning of rotation. The flip-assisting assembly 304 supports the side of the tile body at the lowest point to prevent the tile body from sliding off the side-flipping mechanism.

[0041] As a specific implementation of the structure of the flip-assisting component 304, the flip-assisting component 304 is a disc with a fan-shaped notch, and the central angle of the fan-shaped notch is no more than 90°, so as to facilitate the catching of the lowest side of the sliding tile blank and to stick to the inner wall of one side of the fan-shaped notch, thereby driving the disc to continue to rotate. When the tile blank rotates more than 90°, the inner wall on the other side of the fan-shaped notch applies a flipping thrust to the tile blank as the disc rotates, which is helpful to control the flipping state of the tile blank.

[0042] In order to ensure the normal transportation of the ceramic tile blanks before and after they are overturned, conveyor plates 5 are provided at the tail end of the loading conveyor belt 2 and the head end of the unloading conveyor belt 4. When the ceramic tile blanks are transported to the tail end of the loading conveyor belt 2, the conveyor plates 5 of the loading conveyor belt 2 slide to transport the ceramic tile blanks to the first flip plate 301, so that the middle of the bottom surface of the ceramic tile blanks contacts the top surface of the first flip plate 301, and the conveyor plates 5 of the loading conveyor belt 2 slide back to their original positions. When the ceramic tile blanks are flipped onto the second flip plate 302, the conveyor plates 5 of the unloading conveyor belt 4 slide to contact the side area of ​​the bottom surface of the ceramic tile blanks, and then slide back to their original positions to transport the ceramic tile blanks to the unloading conveyor belt 4, thereby realizing the transportation of the ceramic tile blanks before and after they are overturned. Figure 1 or Figure 2 As shown, a driving slider is provided at the bottom of the conveying plate 5, and the driving slider slides on the slide rail on the base frame 1 to realize the sliding of the conveying plate 5. Furthermore, the conveying plate 5 can be replaced by a slidable transport assembly, which is a small conveying belt arranged in parallel, and the transport assembly slides on the slide rail.

[0043] The above are only preferred embodiments of the present invention, and do not limit the implementation mode and protection scope of the present invention. Those skilled in the art should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the contents of the present invention specification should be included in the protection scope of the present invention.
