Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing equipment, and in particular to a sheet metal feeding and supporting device. Background Technology

[0002] Traditional board drying equipment involves flat conveying of boards within the drying oven, resulting in slow drying speeds, long conveying distances, large space requirements, and high energy consumption. To reduce energy consumption and minimize space requirements during the board drying process, drying equipment typically employs a hinged conveyor mechanism that can lift and stand the boards for conveying, significantly reducing space requirements in the conveying direction. Existing technology includes drying equipment using a hinged circulating conveyor mechanism, where boards are conveyed along a circulating route within the drying oven. When the boards are conveyed from the bottom of the oven, multiple hooks arranged in a row hold the boards in place, providing support and transport. Refer to the working principle of a board drying production line with authorization announcement number CN114353486B; for the unloading equipment in this equipment, refer to the attached manual. Figure 6 After the sheet material is dried, it is unloaded through a sheet material unloading device. During the unloading process, the sheet material is first unhooked by an inclined plane. The lower end of the sheet material is conveyed on the conveyor belt, while the upper end is tilted against the back of the baffle. As the sheet material moves, the tilt angle decreases. The following two problems exist in this process: 1. As the tilt angle of the sheet material decreases, the upper edge of the sheet material abuts against the back of the baffle and generates friction, resulting in wear on the edge of the sheet material; 2. When the sheet material is tilted to a certain angle, such as close to 90°, the baffle can no longer support the upper end of the sheet material. Due to gravity, the sheet material will fall onto the conveyor belt, causing damage to the sheet material. When it falls, the upper edge of the sheet material further rubs against the baffle, damaging the upper edge of the sheet material. Utility Model Content

[0003] To address the above problems, this utility model provides a sheet material feeding and supporting device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A sheet metal feeding and supporting device includes a frame, a receiving conveyor mechanism mounted on the frame, and a feeding conveyor mechanism. The receiving conveyor mechanism includes a receiving conveyor belt, a first supporting frame is provided beside the receiving conveyor belt, and a first supporting part is provided on the top of the first supporting frame. The first supporting frame is rotatably connected to the frame, and a first driving mechanism is connected between the first supporting frame and the frame. The first supporting part rotates as the inclination angle of the sheet metal changes, effectively supporting the sheet metal and preventing it from falling onto the receiving conveyor belt under gravity.

[0006] Preferably, a second support frame is rotatably connected to the end of the first support frame, and a second support portion is provided on the top of the second support frame. A second drive mechanism is connected between the second support frame and the first support frame. The second support portion cooperates with the first support portion and abuts against the bottom of the sheet material, so that the upper edge of the sheet material is disengaged from the baffle, thus preventing the sheet material from being damaged by friction with the baffle.

[0007] Preferably, the first support is a support belt that is annularly sleeved around the first support frame. The support belt is installed by a non-powered driven roller, so that the support belt can move synchronously with the sheet material and play a supporting role, but will not generate relative movement with the sheet material to avoid friction.

[0008] Preferably, the second support is composed of one or more driven rollers. Using rollers can better abut against the back of the sheet material, allowing the upper edge of the sheet material to detach from the baffle.

[0009] Preferably, the first material support frame is located on the left side of the unloading conveyor mechanism. This arrangement allows the first material support frame to support the left end of the sheet material when it falls, so that the sheet material falls smoothly onto the unloading conveyor mechanism.

[0010] Preferably, the receiving conveyor mechanism includes two or more receiving conveyor belts spaced apart, and the unloading conveyor mechanism includes two or more unloading conveyor belts spaced apart. The unloading conveyor belts are inclined downward from left to right, which is conducive to the falling of the sheet material and reduces the falling height of the sheet material on the left side. The unloading conveyor belts are staggered from the receiving conveyor belts, and their ends overlap each other, which is conducive to the sheet material moving from the receiving conveyor belt to the unloading conveyor belt.

[0011] Preferably, the total length of the first support portion and the second support portion when aligned is greater than half the total height of the conveyed plate, ensuring that the bottom of the plate does not leave the feeding conveyor belt when they support the bottom of the plate.

[0012] Preferably, the receiving conveyor belt is inclined upward from left to right to facilitate the unhooking of the sheet material.

[0013] The beneficial effects of this utility model are:

[0014] This invention features a first material support section that holds the sheet metal in place, preventing it from falling directly. A second material support section, working in conjunction with the first, ensures that the upper edge of the sheet metal does not contact the baffle as the tilt angle changes, preventing friction and scratches on the sheet metal's edges. The two-section connection between the first and second material support sections allows the first support section to rotate within a limited space. Once the first support section is rotating, the second support section can then be rotated, effectively extending the total length between them. This supports the upper part of the sheet metal, allowing it to move away from the baffle and preventing friction between the sheet metal and the back of the baffle. Attached Figure Description

[0021] The technical solution of this utility model will be described below with reference to the accompanying drawings and embodiments.

[0022] Reference Figures 1 to 5 The present invention discloses a sheet material feeding and supporting device, comprising a frame 1, a receiving and conveying mechanism 2 and a feeding and conveying mechanism 3 arranged on the frame 1 and positioned at the front and back. The receiving and conveying mechanism 2 includes two or more receiving conveyor belts 21 arranged at intervals. The receiving conveyor belts 21 are inclined upward from left to right. The bottom of the baffle is provided with hooks to hook the sheet material. During rotation, the hooks will extend under the receiving conveyor belts 21, and the sheet material will be lifted by the receiving conveyor belts 21. The baffle continues to rotate, thus allowing the sheet material on the baffle to be unhooked (see background technology for details and principles), which will not be described in detail here. A first material support frame 4 is provided beside the receiving conveyor belt 21. The first material support frame 4 has a first support part 5 on its top. The first material support frame 4 is rotatably connected to the frame 1. A first drive mechanism 6 is connected between the first material support frame 4 and the frame 1. The first drive mechanism 6 can be a conventional mechanism such as a cylinder, hydraulic cylinder or linear motor. The first drive mechanism 6 drives the first material support frame 4 to rotate. When the first material support frame 4 is at its lowest position, it can be hidden under the receiving conveyor belt 21 to avoid affecting the unhooking of the board and the movement of the board. When the board is conveyed from the receiving conveyor belt 21 with the baffle, the first material support frame 4 is located under the receiving conveyor belt 21. After the bottom end of the target board has moved past, the first drive mechanism 6 drives the first material support frame 4 to rotate and support the board. The first support part 5 rotates with the change of the tilt angle of the board, which can effectively support the board and prevent the board from falling onto the receiving conveyor belt 21 under the action of gravity.

[0023] Specifically, a second support frame 7 is rotatably connected to the end of the first support frame 4. A second support part 8 is provided on the top of the second support frame 7. A second drive mechanism 9 is connected between the second support frame 7 and the first support frame 4. The second drive mechanism 9 can be a conventional mechanism such as a cylinder, hydraulic cylinder or linear motor. The second support part 8 cooperates with the first support part 5 to adjust the angle between the first support frame 4 and the second support frame 7, so that the second support part 8 and the first support part 5 abut against the bottom of the board. As the tilt angle of the board decreases, the upper edge of the board disengages from the baffle. The second support part 8 and the board, and the first support part 5 and the board, either roll or move synchronously, to avoid the board rubbing against the baffle and damaging the board.

[0024] By adopting a structure that connects the first support frame 4 and the second support frame 7 in two sections, the first support frame 4 can rotate within a limited space when the second support frame 7 is not rotating. Because the gap between the two baffles is limited, if the length of the first support frame 4 is too long, it will interfere with the baffle. After the first support frame 4 rotates, the second support frame 7 can be rotated, effectively extending the total length between them. Without the participation of the second support frame 4, the first support part 5 can only support the lower part of the center line in the height direction of the plate, which will not allow the upper end of the plate to leave the baffle. By connecting the second support frame 7 to the end of the first support frame 4, the second support part 8 can support the upper part of the plate, allowing the upper end of the plate to leave the baffle and avoiding friction between the plate and the back of the baffle.

[0025] Specifically, the first support part 5 is a support belt 51 that is annularly sleeved around the first support frame 4. The support belt 51 is installed by a non-powered driven roller, so that the support belt 51 can move synchronously with the board and play a supporting role, but will not generate relative movement with the board to avoid friction.

[0026] Specifically, the second support part 8 is composed of one or more driven rollers. The rollers are unpowered and preferably made of a softer material. Using rollers can better support the back of the sheet material, allowing the upper edge of the sheet material to detach from the baffle.

[0027] Specifically, the first material support frame 4 is located on the left side of the unloading conveying mechanism 3. This arrangement allows the first material support frame 4 to support the left end of the sheet material when it falls, so that the sheet material falls smoothly onto the unloading conveying mechanism 3.

[0028] Specifically, the unloading conveying mechanism 3 includes two or more unloading conveyor belts 31 arranged at intervals. The unloading conveyor belts 31 are inclined downward from left to right, which is conducive to the falling of the sheet material and reduces the falling height of the sheet material on the left side. The unloading conveyor belts 31 and the receiving conveyor belts 21 are staggered and their ends overlap each other, which is conducive to the sheet material moving from the receiving conveyor belts 21 to the unloading conveyor belts 31.

[0029] Specifically, when the first support 5 and the second support 8 are aligned, the total length is greater than half the total height of the conveyed plate. When they support the bottom of the plate, the second support 8 is pulled above the center line in the height direction of the plate, ensuring that the bottom of the plate does not leave the feeding conveyor belt 31, the upper end of the plate leaves the baffle, and the feeding conveyor belt 31 carries the plate forward.

[0030] In operation, the first material support frame 4 is located below the receiving conveyor belt 21, and the second material support frame 7 is located below the first material support frame 4. The sheet material is conveyed from the baffle to the receiving conveyor mechanism 2. The receiving conveyor belt 21 is inclined upward from left to right. During the conveying process, the sheet material is lifted by the receiving conveyor belt 21, which allows the sheet material on the baffle to disengage and leave the baffle. As the baffle rotates, the upper end of the sheet material rests against the back of the baffle. When the lower end of the sheet material moves close to the end of the receiving conveyor belt 21, the receiving conveyor belt 21 stops rotating, stopping the lower end of the sheet material. The first material support frame 4 rotates upward. After rotating to the desired position, the second material support frame 7 starts rotating. After positioning, the second support 8 lifts the sheet material to prevent the upper edge of the sheet material from touching the back of the baffle. After the sheet material is lifted, the receiving conveyor belt 21 moves, so that the bottom of the sheet material is transferred to the unloading conveyor belt 31. The second support 8 and the sheet material move or roll synchronously to avoid excessive friction and avoid scratching the sheet material. As the angle between the sheet material and the horizontal plane gradually decreases, the second support frame 7 rotates together and is stored under the first support frame 4 until the back of the sheet material touches the first support 5. The angle of the first support frame 4 then begins to rotate until the upper end of the sheet material falls smoothly onto the receiving conveyor belt 21. The first support frame 4 then rotates to the bottom of the unloading conveyor belt 31, and this process is repeated.
