Description

Technical Field

[0001] This utility model belongs to the field of door frame production technology, and specifically relates to an automatic feeding device for sheet metal in door frame production. Background Technology

[0002] Door frames, also known as door linings or door jambs, are decorative frame structures installed on the inner wall of a doorway. They are not just decorations, but also important components that combine functionality and aesthetics. Automatic board feeding devices in door frame production are key equipment for modern wooden door factories to achieve automation and improve production efficiency.

[0003] Existing automatic board feeding devices for door frame production use one or more sets of vacuum suction cups to adsorb boards through negative pressure. A sturdy gantry frame spans the hopper and processing equipment, and the suction cup sets are installed on the moving slide of the gantry, which can move horizontally and vertically. The automatic feeding of boards is achieved through the action of the gantry and suction cups. However, in actual use, in order to prevent the suction cups from loosening during the movement of the boards, the staff needs to manually support them with straps, which will bring a workload to the production staff. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing an automatic feeding device for door frame production panels. Through a multi-dimensional fixing method of adsorption, horizontal clamping, and lower side support, it forms an extremely stable clamping system that can effectively prevent the panels from sliding, tipping over, or falling during high-speed or long-distance transport, thus ensuring the reliability and safety of the feeding process.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an automatic feeding device for door frame production, including a plate shifting platform, a plurality of suction cups on the lower surface of the plate shifting platform, an air pump inside the plate shifting platform, the suction cups being connected to the air pump, two sliding seats symmetrically distributed around the vertical center of the plate shifting platform being slidably arranged inside the plate shifting platform, clamping blocks being fixedly arranged on the lower surface of each sliding seat, a rotating shaft being rotatably arranged inside each sliding seat, a rotating frame being fixedly arranged between the two ends of each rotating shaft, and a clamping frame being slidably arranged on each rotating frame; a plurality of vertically evenly distributed positioning holes are opened on both sides of the clamping frame, and positioning bolts are threadedly connected between the rotating frame and the adjacent positioning holes.

[0006] As a further improvement of this utility model, two gears symmetrically distributed around the vertical center of the shifting plate are fixedly sleeved on the outer arc surface of the rotating shaft. A support plate is fixedly installed inside the sliding seat. Two sliding columns are fixedly installed between the support plate and the inner wall of the sliding seat away from the vertical center of the shifting plate. Two sliding plates are slidably installed between the two sliding columns. Two rack plates symmetrically distributed around the vertical center of the shifting plate are fixedly installed between the sliding plates. The rack plates are respectively meshed with the adjacent gears. An adjusting screw is rotatably installed between the support plate and the inner wall of the sliding seat away from the vertical center of the shifting plate. The sliding plates are threadedly connected to the adjacent adjusting screw. A servo motor is fixedly installed in the middle of the support plate. The output shaft of the servo motor is fixed to the adjacent adjusting screw through a coupling.

[0007] As a further improvement of this utility model, a drive seat is fixedly installed in the middle of the upper surface of the transfer platform. Two telescopic columns symmetrically distributed about the vertical center of the transfer platform are slidably installed inside the drive seat. Multiple connecting rods are rotatably installed on each telescopic column. Two supports symmetrically distributed about the vertical center of the transfer platform are fixedly installed on the upper surface of the transfer platform. Two guide rails are fixedly installed between the supports and the adjacent drive seats. Two sliding cylinders symmetrically distributed about the vertical center of the transfer platform are fixedly installed on the outer side of the drive seat. Driving components are slidably installed between the sliding cylinders and the two adjacent guide rails. The ends of the connecting rods away from the telescopic columns are rotatably connected to the adjacent driving components. The telescopic columns are respectively connected and fixed to the adjacent sliding seats. Two adjusting screws 2 symmetrically distributed about the vertical center of the transfer platform are rotatably installed inside the drive seat. The adjusting screws 2 are respectively threadedly connected to the adjacent driving components. A dual-axis motor is installed in the middle of the drive seat. The output shaft of the dual-axis motor is fixed to the adjacent adjusting screws 2 by a coupling.

[0008] As a further improvement of this utility model, a lifting frame is fixedly installed on the upper surface of the transfer platform, the transfer platform is slidably installed inside the gantry frame, rollers are rotatably installed at the four corners of the lower end of the gantry frame, a support frame is installed on the outer side of the gantry frame, two slide rails are fixedly installed inside the support frame, and the gantry frame is slidably installed between the two slide rails; an electric push rod one is fixedly installed on the upper side of the support frame, the telescopic end of the electric push rod one is connected and fixed to the gantry frame, and an electric push rod two is fixedly installed at the top inside the gantry frame, the telescopic end of the electric push rod two is connected and fixed to the lifting frame.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: Firstly, a vacuum negative pressure is generated by controlling the suction cup with an air pump to achieve initial adsorption and fixation of the board. Next, a dual-axis motor drives the telescopic column, which moves the clamping blocks from the horizontal direction to the opposite side to clamp the board laterally. Finally, a servo motor drives the rotating frame to move in an arc trajectory by adjusting the transmission of the lead screw, rack and pinion plate and gears, so that the clamping frame applies a supporting force from below the board. This multi-dimensional fixing method of adsorption + horizontal clamping + lower side support constitutes an extremely stable clamping system, which can effectively prevent the board from sliding, tipping or falling during high-speed or long-distance transfer, ensuring the reliability and safety of the loading process.

[0010] Secondly, the spacing of the horizontal clamping mechanism (clamping blocks) and the angle and height of the vertical supporting mechanism (clamping frame) can be precisely adjusted by the motor. This means that the same equipment can quickly adapt to plates of different lengths, widths and thicknesses, greatly enhancing the versatility of the equipment. It is particularly suitable for flexible production needs of multiple varieties and small batches. Operators can mechanically lock the clamping frame by sliding it and tightening the bolts. This design allows for flexible adjustment according to the thickness of the plate.

[0011] Thirdly, the horizontal and vertical movement of the transfer table (controlled by electric push rod one and electric push rod two), the suction cup's picking up and releasing, and the execution of clamping and supporting actions are all centrally coordinated and controlled by the electronic control system. This highly automated design enables "one-click" operation from sheet material conveying to precise feeding, greatly reducing manual intervention, lowering the labor intensity of operators, and significantly improving the cycle time and efficiency of the entire production process. The system provides a foundation for continuous material supply and helps meet the needs of 24-hour uninterrupted production. Attached Figure Description

[0016] like Figure 3 , 4 As shown, the device includes a transfer platform 201. Multiple suction cups 202 are provided on the lower surface of the transfer platform 201. An air pump 203 is installed inside the transfer platform 201, and the suction cups 202 are all connected to the air pump 203.

[0017] like Figure 3 , 4As shown, two gears 213 are fixedly fitted on the outer arc surface of the rotating shaft 206, symmetrically distributed around the vertical center of the shifting platform 201. Support plates 209 are fixedly installed inside the sliding seats 204.

Two sliding plates 211 are slidably installed between the two sliding pillars 210. Two gears 213 symmetrically distributed around the vertical center of the shifting platform 201 are fixedly installed between the sliding plates 211. Symmetrically distributed rack plates 212 are connected to adjacent gears 213 respectively; an adjusting screw 214 is rotatably provided between the support plate 209 and the inner wall of the sliding seat 204 away from the vertical center of the moving plate platform 201; the sliding plate 211 is threadedly connected to the adjacent adjusting screw 214; a servo motor 215 is fixedly provided in the middle of the support plate 209; the output shaft of the servo motor 215 is fixed to the adjacent adjusting screw 214 through a coupling.

[0018] like Figure 2 , 3 As shown, a drive seat 301 is fixedly installed in the middle of the upper surface of the shifting platform 201. Two telescopic columns 302 are slidably arranged inside the drive seat 301, symmetrically distributed around the vertical center of the shifting platform 201. Multiple connecting rods 306 are rotatably mounted on each telescopic column 302. Two supports 303 are fixedly installed on the upper surface of the shifting platform 201, symmetrically distributed around the vertical center of the shifting platform 201. Two guide rails 304 are fixedly installed between each support 303 and the adjacent drive seat 301. Two sliding cylinders 307 are fixedly installed on the outer side of the drive seat 301, symmetrically distributed around the vertical center of the shifting platform 201. A drive component 305 is slidably arranged between the 07 and the two adjacent guide rails 304. The end of the connecting rod 306 away from the telescopic column 302 is rotatably connected to the adjacent drive component 305. The telescopic column 302 is fixedly connected to the adjacent sliding seat 204. The drive seat 301 is rotatably arranged with two adjusting screws 308 symmetrically distributed around the vertical center of the moving plate platform 201. The adjusting screws 308 are threadedly connected to the adjacent drive component 305. A dual-axis motor 309 is arranged in the middle of the drive seat 301. The output shaft of the dual-axis motor 309 is fixed to the adjacent adjusting screw 308 by a coupling.

[0019] like Figure 1 , 2As shown, a lifting frame 106 is fixedly installed on the upper surface of the shifting platform 201. The shifting platform 201 is slidably installed inside the gantry frame 103. Rollers 104 are rotatably installed at the four corners of the lower end of the gantry frame 103. A support frame 101 is installed on the outer side of the gantry frame 103. Two slide rails 102 are fixedly installed inside the support frame 101. The gantry frame 103 is slidably installed between the two slide rails 102. An electric push rod 105 is fixedly installed on the upper side of the support frame 101. The telescopic end of the electric push rod 105 is connected and fixed to the gantry frame 103. An electric push rod 207 is fixedly installed at the top of the inside of the gantry frame 103. The telescopic end of the electric push rod 207 is connected and fixed to the lifting frame 106.

[0020] In use, the support frame 101 is moved to a designated position, and then the electric push rod 105 and the electric push rod 107 are controlled to operate. The telescopic end of the electric push rod 105 drives the gantry frame 103 to slide between the two slide rails 102, and the telescopic end of the electric push rod 107 drives the lifting frame 106 to rise or fall. This causes the plate-shifting platform 201 fixedly installed on the lower side of the lifting frame 106 to move horizontally and vertically. As a result, the plate-shifting platform 201 moves under the drive of the electric push rods 105 and 107 to approach the plate material that has been conveyed to the lower side of the support frame 101 by the external conveying device. Then, the air pump 203 is controlled to operate, so that the air pump 203 controls the suction cup 202 to suck up air, thereby absorbing the conveyed plate material. Then, the dual-axis motor 309 is controlled to run, and the threaded relationship between the dual-axis motor 309 and the telescopic column 302 drives the telescopic column 302 to move towards or away from each other. This causes the telescopic column 302 to drive the sliding seats 204 on both sides to move towards or away from each other. During the movement of the telescopic column 302, the telescopic column 302 rotates with the connecting rod 306, and the connecting rod 306 rotates with the driving component 305. This causes the driving component 305 to slide between the slide cylinder 307 and the two adjacent guide rails 304. The sliding friction damping between the driving component 305 and the slide cylinder 307 and the guide rails 304 helps the telescopic columns 302 on both sides to move towards or away from each other stably. During the movement of the sliding seats 204 towards or away from each other, the clamping blocks 205 installed and fixed on the sliding seats 204 move towards or away from each other, so that the clamping blocks 205 can be horizontally close to the plate to be transferred and clamp and fix it. The clamping frames 208 on both sides are slidable, so that the clamping frame 208 and the rotating frame 207 slide together, thereby allowing the clamping frame 208 to adapt to the thickness of the plate that needs to be supported. Then, the bolts are tightened by external tools to fix the clamping frame 208 and the rotating frame 207, thereby achieving the adjustment of the clamping frame 208. Then, the servo motor 215 is controlled to run, so that the output shaft of the servo motor 215 drives the adjusting screw 214 connected to it to rotate. Then, through the thread relationship between the adjusting screw 214 and the slide plate 211, the rack plates 212 on both sides move towards each other or away from each other. Then, through the meshing relationship between the rack plates 212 and the gear 213, the rotating shaft 206 where the gear 213 is located rotates. Then, the rotating shafts 206 on both sides rotate synchronously towards each other, which in turn drives the rotating frames 207 on both sides to rotate synchronously towards each other. Then, the rotating frames 207 drive the clamping frame 208 to approach and support the plate in an arc trajectory, which makes it easier to support the plate from the bottom and clamp and fix it from the top and bottom during the subsequent loading process. After the board is picked up, the servo motor 215 and the dual-axis motor 309 work together to clamp and fix the board in the horizontal and vertical directions. Then, the electric push rod 105 and the electric push rod 207 are controlled to make the transfer table 201 move the clamped board to feed it. When the board is fed to the designated position by the transfer table 201, the air pump 203, the dual-axis motor 309 and the servo motor 215 are controlled to release it, so that the board can be fed quickly and stably in a fully automatic manner.

Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
