Description

Technical Field

[0001] The invention relates to the technical field of plate processing equipment, in particular to an automatic turning-over processing device for fire door plates. Background Art

[0002] Fire doors are an important building safety device specially designed to prevent the spread of fire. They have a wide range of applications and are mainly used in various public facilities and residential buildings. Fire doors can effectively separate fire sources, slow the spread of fire, and buy precious time for personnel evacuation. The materials of fire doors can be divided into wooden fire doors, steel fire doors, steel-wood fire doors, etc. Wooden fire doors use flame-retardant wood products as door frames, door leaf frames, and door leaf panels. These woods need to be smoothed on both sides before being installed on the fire doors. Only by ensuring the flatness of the two planes of the wooden board can the flatness of the subsequent fire door body be guaranteed. These wooden boards used as door bodies are often large in area, thick, and therefore heavy. Therefore, when grinding the two sides of the door panels, if you rely on manual flipping of the door panels, it will be very laborious and easy to cause safety accidents.

[0003] The technical content disclosed in the Chinese patent document (publication number: CN220462993U, patent name: automatic plate turning device) is as follows: it includes a concave support plate, and a turning mechanism is provided in the concave support plate. After the plate is placed in the turning frame, the second drive motor is started to drive the output end to drive the bidirectional screw to rotate through the second rotating rod, so that the splint moves along the bidirectional screw through the threaded holes opened on the top surfaces of the connecting blocks on both sides, and the limit slider is used to limit the sliding during movement, so that the upper and lower symmetrical splints can make relative movement operations, and then the plates of different thicknesses can be adjusted and fixed according to the thickness of the plates, thereby improving the flexibility of the automatic plate turning device during use. After the fixing is completed, the turning mechanism is set, and the gear is driven to rotate by the output end of the first drive motor, and then the outer gear ring is driven to rotate, so as to complete the automatic turning operation of the plates fixed between the turning frames.

[0004] From the above implementation scheme, it can be seen that although the automatic plate turning equipment is equipped with a turning rack to place the plates and turn them over, it is not equipped with an automatic mechanism to move the plates to the turning rack. Therefore, it is still necessary to manually move the plates and place them on the turning rack, which is still a very heavy task for the operator. Summary of the Invention

[0005] The invention overcomes the shortcomings of the prior art and is equipped with a flipping conveyor assembly. The plates can be directly conveyed into the flipping conveyor assembly from an external conveying mechanism. The clamping assemblies on both sides of the flipping conveyor assembly clamp the plates and then flip them. Therefore, the entire process does not require manual participation, which reduces labor costs and can also avoid the occurrence of safety accidents to the greatest extent. In order to solve the above technical problems, the invention is achieved through the following technical solutions: An automatic flipping processing device for fire door panels comprises a base, a flip frame is rotatably arranged on the base, a flip conveying assembly is arranged at the center of the flip frame, and clamping assemblies are arranged on both sides of the flip conveying assembly; The rotation of the flip frame drives the flip conveyor assembly to rotate.

Furthermore, the base is connected to a flip power assembly, which includes a first motor and a chain. The chain surrounds the outer periphery of the flip frame. The first motor drives the chain to rotate, and the rotation of the chain drives the flip frame to rotate.

[0007] Furthermore, the flip frame includes a first connecting rod and a second connecting rod arranged in parallel, and both ends of the first connecting rod and the second connecting rod are connected to the turntable. Furthermore, the turntable is provided with a chain groove, and the chain is embedded in the chain groove.

[0015] The preferred embodiments of the invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the invention and are not used to limit the invention.

[0016] like Figures 1 to 5 The automatic flipping processing device for fire door panels shown in the figure includes a base 1, a flip frame 2 is rotatably arranged on the base 1, a flip conveying assembly 5 is arranged at the center of the flip frame 2, and clamping assemblies 4 are arranged on both sides of the flip conveying assembly 5; the panels can be directly transported into the flip conveying assembly 5 from the external conveying mechanism, and the clamping assemblies 4 on both sides of the flip conveying assembly 5 clamp the panels and then flip them, so the whole process does not require manual participation, which reduces labor costs and can also avoid the occurrence of safety accidents to the greatest extent.

[0017] The rotation of the flip frame 2 drives the flip conveyor assembly 5. One end of the flip conveyor assembly 5 is connected to an external conveying mechanism. When the flip conveyor assembly 5 rotates to a position parallel to the bottom surface of the base 1, the external conveying mechanism conveys the wooden board onto the flip conveyor assembly 5. The clamping assembly 4 clamps the board, and then the flip conveyor assembly 5 rotates 180 degrees to flip the board over. The flip conveyor assembly 5 is equipped with a conveyor shaft. After the board is flipped, the conveyor shaft rotates to send the board out of the flip conveyor assembly 5. This ensures that the board can be moved and transported on the flip conveyor assembly 5 while ensuring that the board does not shift during flipping, and ensures the stability of the board's relative position to the flip conveyor assembly 5 during flipping.

[0018] The flip conveyor assembly 5 includes a transmission shaft mounting crossbar 501, which includes a first transmission shaft 502 and a second transmission shaft 503. The first transmission shaft 502 and the second transmission shaft 503 are respectively arranged on both sides of the transmission shaft mounting crossbar 501; a second motor 504 is provided on one side of the transmission shaft mounting crossbar 501, and the second motor 504 is connected to a linkage sprocket component 506, which is connected to a main transmission shaft 505, which is connected to a first belt 507 and a second belt 508; the first belt 507 is connected to the second transmission shaft 503, and the second belt 508 is connected to the first transmission shaft 502. Therefore, the second motor 504 can simultaneously drive the first transmission shaft 502 and the second transmission shaft 503 to rotate. Compared with the traditional method of requiring multiple motors to drive multiple transmission shafts to rotate, a driving power source is saved, which saves the cost of manufacturing the equipment. The base 1 is connected to the flip power assembly 3, which includes a first motor 301 and a chain 303. The chain 303 surrounds the outer periphery of the flip frame 2. The first motor 301 drives the chain 303 to rotate, and the rotation of the chain 303 drives the flip frame 2 to rotate.

[0019] The turning frame 2 includes a first connecting rod 201 and a second connecting rod 202 arranged in parallel. Both ends of the first connecting rod 201 and the second connecting rod 202 are connected to a turntable 203. The turntable 203 is provided with a chain groove 2031, and a chain 303 is embedded in the chain groove 2031. The automatic turning processing device of the present invention uses the chain 303 to drive the turning frame 2 to rotate. Compared with the traditional method of using gear meshing to achieve rotation, the structure is simpler, the cost is lower, and it is convenient for repair and daily maintenance. In this real-time example, a sensor plate is provided in the middle of the base, and sensors are provided on the first connecting rods 201 on the upper and lower sides of the flip frame 2. When one of the first connecting rods 201 rotates 180 degrees from the upper end of the flip frame 2 to the lower end of the flip frame 2, the sensor on the first connecting rod 201 approaches the sensor plate in the middle of the base, and the device senses that the flip conveyor assembly 5 has completed a 180-degree rotation, indicating that the wooden board has been flipped. At this time, the first motor 301 stops driving the chain 303, and the flip conveyor assembly 5 pushes the flipped wooden board out, then feeds the second wooden board into the flip conveyor assembly 5. The flip frame 2 then rotates 180 degrees in the opposite direction, causing the second wooden board to be flipped. After the flip frame 2 rotates in the opposite direction, the sensor on the other first connecting rod 201 opposite the previous first connecting rod 201 approaches the sensor plate in the middle of the base, indicating that the second wooden board has been flipped. This process is repeated, and the wooden boards fed into the flip conveyor assembly 5 are flipped one by one. In this embodiment, the sensor is a proximity switch.

[0020] The turning power assembly 3 also includes a turntable card wheel 304, which is provided with an embedded groove 3041. The side edges of the chain groove 2031 are embedded in the embedded groove 3041. The turntable card wheel 304 is rotatably connected to both sides of the base 1. The turntable card wheel 304 supports the turntable 203. The embedded groove 3041 limits the movement of the turning frame 2 in a direction perpendicular to the turntable 203, thereby ensuring the stability of the turntable 203.

[0021] Sprockets 302 are rotatably connected to both sides of the base 1, and the first motor 301 is connected to one of the sprockets 302, which is meshed with the chain 303. Therefore, the first motor 301 can drive the flip frame 2 to rotate.

[0022] The clamping assembly 4 includes a clamping power component 401, the output end of which is connected to a clamping plate 402. A rubber pad is provided on one side of the clamping plate 402. In this embodiment, the clamping power component 401 is a pneumatic cylinder. When the output end of the clamping power component 401 pushes the clamping plate 402 out, the clamping plate 402 clamps the wooden board from two planes. The rubber pad contacts the wooden board, preventing scratches from contact. The rubber pad also increases the friction between the clamping plate 402 and the board, ensuring a more secure clamping of the board. Finally, it should be noted that the above are only preferred embodiments of the invention and are not intended to limit the invention. Although the invention has been described in detail with reference to the embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. However, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the invention should be included in the scope of protection of the invention.
