When the suction cylinder 231 moves upward, the sealing ring 2311 can tightly fit the bottom surface of the plate material 80 on the receiving disc 22.

[0040] In addition, when the suction cylinder 231 moves downward, the sealing ring 2311 is separated from the plate material 80, and the sealing ring 2311 is lower than the conveying wheel 241. At this time, the plurality of conveying wheels 241 can realize the smooth transfer of the plate material 80.

[0041] The suction member 23 in the embodiment of the present application is arranged at the middle part of the receiving disc 22, and the mounting seat 232 and the lifting frame 233 are both in the shape of a snake in cooperation, which helps to improve the suction positioning effect on the plate 80.

[0042] The conveying unit is composed of a plurality of conveying wheels 241 arranged in parallel. The plurality of conveying wheels 241 are connected with the synchronous driving member 60. The top surface of the receiving disc 22 is provided with a plurality of grooves 221, and is internally provided with a containing chamber (not shown in the figure), and the conveying wheels 241 are arranged in the corresponding grooves 221. The synchronous driving member 60 in the embodiment has the function of controlling the synchronous and same-direction rotation of the plurality of conveying wheels 241, thereby assisting the movement and positioning of the plate 80 on the receiving disc 22. Specifically, the synchronous driving member 60 can include a motor 61, a plurality of gear sets 62, and a plurality of parallel rotating rollers 63, wherein each gear set 62 can include a main gear 621 and a slave gear 622 in engagement, wherein the central shaft of each conveying wheel 241 penetrates the containing chamber and is connected with the corresponding slave gear 622, and the main gear 621 is sleeved on the corresponding rotating roller 63. Each rotating roller 63 is movably arranged in the containing chamber, and one of the rotating rollers 63 is connected with the motor 61, and the plurality of rotating rollers 63 are connected through a linkage member 70. It should be noted that the linkage member 70 described in the embodiment has the function of controlling the synchronous and same-direction rotation of the plurality of rotating rollers 63, and the linkage member 70 can refer to the driving mode of the existing conveying belt. Specifically, the linkage member 70 can include a plurality of sprockets 71 and a chain 72, wherein the sprocket 71 and the rotating roller 63 correspond one-to-one, the plurality of sprockets 71 are respectively sleeved on the outside of the corresponding rotating rollers 63, and one chain 72 is sleeved on the outside of the adjacent two sprockets 71.

[0043] It should be noted that the conveying wheel 241 in the embodiment is provided with a friction layer made of rubber, silicone or the like on the outside, which can improve the friction force when the conveying wheel 241 is attached to the plate 80, thereby facilitating the smooth conveying of the plate 80.

[0044] In the embodiment of the present application, the main gear 621, the slave gear 622 and the conveying wheel 241 correspond one-to-one. The rotating roller 63 connected with the motor 61 is driven to rotate, the sprocket 71 on the outside of the rotating roller 63 drives the chain 72 engaged therewith to run, and then drives another rotating roller 63 on the inside of the chain 72 to rotate synchronously and in the same direction. Under the cooperation of the plurality of sprockets 71 and the chain 72, the plurality of rotating rollers 63 rotate synchronously and in the same direction. At the same time, under the driving of the plurality of gear sets 62, the plurality of conveying wheels 241 also rotate synchronously and in the same direction, thereby ensuring the smooth conveying of the plate 80.

[0045] The limiting module 30 is provided with at least two groups, and each limiting module 30 can include a plurality of limiting pieces 31, wherein the plurality of limiting pieces 31 are provided in at least two rows in parallel, and the two rows of limiting pieces 31 are symmetrically arranged, and each limiting piece 31 is provided with a telescopic end, and the height of the telescopic end is higher than the height of the conveying wheel 241. The limiting piece 31 described in the embodiment can adopt a vertically arranged air cylinder, and the output end of the air cylinder is the telescopic end. The height of the output end can be flexibly controlled through the air cylinder, and the effective limiting of the plate 80 can be realized in the process of entering the receiving disc 22.

[0046] In the embodiments of the present application, with reference to Figure 7 , two groups of limiting modules 30 can respectively implement blocking and limiting operations on the plates entering the receiving disc 22 in the transverse and longitudinal directions. Meanwhile, each limiting module 30 is provided with at least two rows of a plurality of limiting pieces 31. By selecting two corresponding limiting pieces 31 located on the same straight line, the two limiting pieces 31 can be in contact with the edges of the plates entering the receiving disc 22, and can effectively ensure that the plates are placed in the correct position, thereby providing a strong guarantee for the accurate positioning of the plates.

[0047] One end of the positioning arm 40 extends to the input end of the edge banding machine 901, and one side of the positioning arm 40 is provided with a positioning module 41. The positioning module 41 can include a side wheel group 411 arranged in a shape of and two main wheel groups 412, wherein the two main wheel groups 412 are parallel to each other and connected to the opposite driving parts 13. The side wheel group 411 can include a side plate 4111 and a plurality of side wheels 4112 arranged in parallel on the side plate 4111, and the side plate 4111 is fixedly arranged on the positioning arm 40. The main wheel group 412 can include a main plate 4121 and a plurality of main wheels 4122 arranged in parallel on the main plate 4121, and the opposite driving parts 13 are arranged on the other side of the positioning arm 40, and the output ends of the opposite driving parts 13 are connected to the two main plates 4121, respectively. It should be noted that the opposite driving parts 13 described in the embodiment can be a double-acting cylinder, and the two output ends of the double-acting cylinder are connected to the two main plates 4121, respectively. Starting the double-acting cylinder can realize the relative (mutual approach or mutual separation) movement of the two main plates 4121, thereby realizing the clamping positioning of the plate 80.

[0048] The main wheel group 412 is provided with a plurality of avoidance openings 4123 for avoiding the corresponding conveying wheels 241. It can be understood that the conveying wheels 241 that need to be avoided are located at the edges of the receiving disc 22.

[0049] It should be noted that the two ends of the external rotary conveyor production line are respectively arranged near the outlet of the edge banding machine 901 and the other end of the base 10 away from the positioning arm 40, and such a layout enables the device to smoothly receive the plate 80 output from the rotary conveyor production line and send it to the inlet of the edge banding machine 901. At the same time, the device can also reverse the plate 80 during the transfer process.

[0050] Specifically, when the plate 80 with single edge banding needs to be loaded, the relevant personnel first adjusts the two limiters 31 (which are located on the same straight line) according to different sizes of the plate 80, so that the telescopic end of the adjusted limiter 31 moves up and is higher than the conveying wheel 241.

[0051] Then, the plate 80 is conveyed to the receiving disc 22 by the external rotary conveyor production line, and in this process, the relevant personnel control the synchronous rotation of the plurality of conveying wheels 241 through the synchronous driving member 60 to assist the transfer of the plate 80. When one end of the plate 80 contacts the two limiters 31, the conveying wheel 241 stops rotating, thereby completing the transfer of the plate 80.

[0052] After the plate 80 is located on the receiving disc 22, the relevant personnel control the lifting frame 233 and the plurality of suction cylinders 231 to move up through the lifting member 14, so that the suction cylinder 231 moves up to tightly contact the plate 80 on the receiving disc 22. Then, the external suction fan is started, and the external suction fan generates suction force on the plurality of branch conduits 51 through the main conduit 52, and the branch conduit 51 adsorbs the plate 80 through the corresponding suction cylinder 231, thereby realizing the fixation of the plate 80. Subsequently, the receiving disc 22 can be driven to rotate 90 degrees by the rotating member 12, thereby completing the reversing operation of the plate 80.

[0053] Subsequently, the plate 80 is transferred. First, the telescopic end of the adjusted limiter 31 is controlled to move down and reset, so that the limiter 31 is lower than the transfer frame 21. Then, the transfer frame 21 is driven to move towards the positioning arm 40 by the moving member 11.

[0054] When one side of the plate 80 enters between the upper and lower main wheels 4122 and contacts the side wheel 4112, the relevant personnel immediately control the two main plates 4121 to approach each other through the relative driving member 13, so that the plurality of main wheels 4122 clamps and positions the plate 80.

[0055] Finally, the relevant personnel control the plurality of conveying wheels 241 to rotate and accurately convey the plate 80 to the edge banding machine 901, thereby realizing the accurate loading operation of the plate 80.

[0056] In conclusion, the plate edge sealing reversing device of the embodiment of the present application can realize accurate reversing and feeding of the plate, can be flexibly adapted to plate processing scenarios of different sizes, and can significantly improve the overall efficiency of plate edge sealing.
