Description

Technical Field

[0001] This utility model belongs to the field of metal sawing technology, and relates to a feeding device, particularly a continuous feeding device for metal sawing. Background Technology

[0002] Metal band saws are the main machine tools for processing various metal materials. They consist of a frame (worktable), columns and beams, a transmission mechanism (motor or reducer), and a feed mechanism. Metal band saws are mainly used for processing low-alloy steel, high-alloy steel, special alloy steel, and stainless steel. They are classified by structure as horizontal and vertical; and by function as semi-automatic, fully automatic, and CNC. Horizontal band saws can be further divided into double-column and scissor types. Currently, when using metal band saws to process and cut metal materials, the materials are usually manually transported to the saw for cutting, which is physically demanding and unsafe. Due to the weight of the metal materials, only individual pieces can be fed and cut at a time, significantly reducing cutting efficiency.

[0003] A search revealed a Chinese patent document disclosing a feeding device for a metal band saw [Application No.: 202321075090.1; Publication No.: CN 219724800 U]. This feeding device for a metal band saw includes a feeding unit with several mounting frames fixed at equal intervals on its top. A feeding roller supporting the metal material is rotatably mounted inside each mounting frame. The feeding unit has a first feeding frame, and a second feeding frame is located on one side of the first feeding frame. This application, through the combination of the feeding roller, the first feeding frame, and the second feeding frame, allows the feeding clamps inside the first and second feeding frames to clamp the metal material near its sidewalls when it is placed inside the feeding unit. This enables simultaneous clamping and feeding of multiple pieces of metal. Furthermore, the movement of the first and second feeding frames facilitates bringing the metal material closer to the metal band saw for cutting. A pusher plate is added to the second feeding frame to apply a pushing force to the end of the metal material, achieving a good feeding effect.

[0004] Although the feeding mechanism disclosed in this patent can realize the feeding operation of multiple metal materials, it needs to perform reciprocating motion during feeding, which cannot guarantee the continuity of transportation. Moreover, when transporting multiple metal materials at the same time, due to their large weight, relative slippage is likely to occur, affecting the stability of transportation. Summary of the Invention

[0005] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a continuous feeding device for metal sawing machines. The technical problem this utility model aims to solve is: how to achieve continuous and stable conveying of raw material plates.

[0006] The objective of this utility model can be achieved through the following technical solutions: A continuous feeding device for a metal saw includes a frame, with legs on the lower side of the frame, and mounting frames symmetrically fixed on the upper side of the frame. A drive motor is fixed on the mounting frame, and a belt roller is rotatably connected to the mounting frame. A conveyor belt is mounted on the drive roller, and the output shaft of the drive motor is fixedly connected to the drive roller. Several push blocks are fixed on the belt roller, and several conveying rollers are rotatably connected to the frame. The lower side of the push blocks is higher than the uppermost end of the conveying rollers.

[0007] The working principle of this utility model is as follows: During operation, the raw material sheet is placed on the conveyor roller, the drive motor is turned on, and the distance between the two push blocks is greater than the length of the raw material sheet. The drive motor drives the conveyor belt to rotate through the drive roller, and the conveyor belt drives the push blocks to move, thereby pushing the push blocks against the rear end of the raw material sheet. This allows the raw material sheet to move on the conveyor roller with high stability and no relative sliding with the conveyor roller, ensuring the stability of sawing. At the same time, multiple push blocks are provided, which can convey multiple raw material sheets at the same time to achieve continuous feeding.

[0008] A placement box is fixed to the upper end of the frame. The placement box has a door on the front side and a discharge port at the lower end.

[0009] With the above structure, during operation, the raw material sheet is placed in the placement box. The height of the pusher block is lower than the thickness of the raw material sheet. The pusher block can push the bottom raw material sheet away from the bottom of the placement box. After the raw material sheet leaves the placement box, the next raw material sheet in the placement box will automatically fall onto the conveyor roller under the action of gravity, thus realizing the rapid feeding of raw material sheets.

[0010] The pusher block has an inclined surface on its left side.

[0011] With the above structure, the inclined plane can be used to guide and buffer the raw material sheet as it falls from the placement box, thereby reducing the falling speed of the raw material sheet and improving the stability of the operation.

[0012] The outrigger is equipped with a drive mechanism, which is connected to a first support rod and a second support rod. A lifting plate is fixed to the upper end of the first support rod, a shock absorber is fixed to the lifting plate, a connecting plate is fixed to the upper end of the shock absorber, and a moving wheel is fixed to the lower end of the second support rod.

[0013] With the above structure, during operation, the drive mechanism can retract the moving wheels into the outriggers, while the shock absorbers extend out of the outriggers. The shock absorbers can be used to dampen and buffer the vibrations generated during operation, extending the service life of the device. When moving, the moving wheels can be extended to facilitate the movement of the device. When stored and not in operation, the moving wheels and shock absorbers can be completely retracted into the outriggers to prevent them from being subjected to long-term pressure and to extend their service life.

[0014] The rotating column has a drive track inside, and an annular opening on the outer periphery of the drive track. A first moving column and a second moving column are slidably connected inside the drive track. A first support rod extends into the drive track and is fixedly connected to the first moving column. The upper end of the second support rod extends into the drive track and is fixedly connected to the second moving column. The drive track consists of a smooth part, a first curved part, and two second curved parts, which are symmetrically arranged on the left and right.

[0015] With the above structure, when switching between the states of the moving wheel and the shock absorber, the rotating column can be rotated by a rotary motor. When the shock absorber needs to extend, the first curved part is located directly below, the second moving column is located inside the first curved part, and the second moving column is located on the smooth part, thus allowing the shock absorber to extend and the moving wheel to retract. When the moving wheel and the shock absorber need to be fully retracted into the outrigger, the first and second moving columns can be located in the two second curved parts respectively. When the moving wheel and the shock absorber need to be fully extended from the outrigger, the first and second moving columns can be located on the smooth part. This structure allows for switching between multiple states by rotating the rotating column. It is simple in structure, easy to operate, and highly practical.

[0016] Compared with existing technologies, the continuous feeding device for metal sawing machines has the following advantages: 1. During operation, the raw material sheet is placed on the conveyor roller, the drive motor is turned on, and the distance between the two push blocks is greater than the length of the raw material sheet. The drive motor drives the conveyor belt to rotate through the drive roller, and the conveyor belt drives the push blocks to move, thereby pushing the rear end of the raw material sheet. This allows the raw material sheet to move on the conveyor roller with high stability and no relative slippage with the conveyor roller, ensuring the stability of sawing. At the same time, multiple push blocks are set, which can convey multiple raw material sheets at the same time to achieve continuous feeding.

[0017] 2. During operation, the raw material sheet is placed in the placement box. The height of the pusher block is lower than the thickness of the raw material sheet. The pusher block can push the bottom raw material sheet away from the bottom of the placement box. After the raw material sheet leaves the placement box, the next raw material sheet in the placement box will automatically fall onto the conveyor roller under the action of gravity, thus realizing the rapid feeding of raw material sheets.

[0018] 3. During operation, the drive mechanism can be used to retract the moving wheels into the outriggers, while the shock absorbers can be extended out of the outriggers. The shock absorbers can be used to dampen and buffer the vibrations generated during operation, thus extending the service life of the device. When moving, the moving wheels can be extended to facilitate the movement of the device. When stored and not in operation, the moving wheels and shock absorbers can be completely retracted into the outriggers to prevent them from being subjected to pressure for a long time and to extend their service life.

Detailed Implementation

[0024] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0025] like Figures 1-4 As shown, the continuous feeding device for metal sawing machines includes a frame 1, with support legs 2 on the lower side of the frame 1. Mounting frames 6 are symmetrically fixed on the upper side of the frame 1, with a drive motor 8 fixed on the mounting frame 6. A belt roller is rotatably connected to the mounting frame 6, and a conveyor belt 7 is mounted on the drive roller. The output shaft end of the drive motor 8 is fixedly connected to the drive roller. Several push blocks 9 are fixed on the belt roller, and several conveying rollers 5 are rotatably connected to the frame 1. The lower side of the push block 9 is higher than the uppermost end of the conveying roller 5.

[0026] During operation, the raw material sheet is placed on the conveyor roller 5, and the drive motor 8 is turned on. The distance between the two push blocks 9 is greater than the length of the raw material sheet. The drive motor 8 drives the conveyor belt 7 to rotate through the drive roller, and the conveyor belt 7 drives the push blocks 9 to move. This allows the push blocks 9 to push the rear end of the raw material sheet, so that the raw material sheet can move on the conveyor roller 5. The movement is highly stable and will not slip relative to the conveyor roller 5, ensuring the stability of sawing. At the same time, multiple push blocks 9 are provided, which can convey multiple raw material sheets at the same time to achieve continuous feeding.

[0027] The upper end of the frame 1 is fixed with a placement box 3, the front side of the placement box 3 is provided with a box door 4, and the lower end of the placement box 3 is provided with a discharge port.

[0028] With the above structure, during operation, the raw material sheet is placed in the placement box 3. The height of the push block 9 is lower than the thickness of the raw material sheet. The push block 9 can push the bottom raw material sheet away from the bottom of the placement box 3. After the raw material sheet leaves the placement box 3, the next raw material sheet in the placement box 3 will automatically fall onto the conveyor roller 5 under the action of gravity, thus realizing the rapid feeding of the raw material sheet.

[0029] The pusher block 9 has an inclined surface on its left side.

[0030] With the above structure, when the raw material sheet falls from the placement box 3, the inclined plane can be used for guidance and buffering, thereby reducing the falling speed of the raw material sheet and improving the stability of the operation.

[0031] The support leg 2 is equipped with a drive mechanism, which is connected to a first support rod 14 and a second support rod 18. A lifting plate 15 is fixed to the upper end of the first support rod 14, and a shock absorber 16 is fixed to the lifting plate 15. A connecting plate 17 is fixed to the upper end of the shock absorber 16. A moving wheel 19 is fixed to the lower end of the second support rod 18. The outer periphery of the lifting plate 15 abuts against the inner periphery of the support leg 2, and the outer periphery of the wheel seat on the moving wheel 19 abuts against the inner periphery of the support leg 2.

[0032] With the above structure, during operation, the drive mechanism can retract the moving wheel 19 into the support leg 2, while the shock absorber 16 extends out of the support leg 2. The shock absorber 16 can be used to dampen and buffer the vibration generated during operation, extending the service life of the device. When moving, the moving wheel 19 can be extended to facilitate the movement of the device. When stored and not in operation, the moving wheel 19 and the shock absorber 16 can be completely retracted into the support leg 2 to prevent the moving wheel 19 and the shock absorber 16 from being subjected to pressure for a long time, thus extending their service life.

[0033] The rotating column 11 has a drive rail 21 inside, and an annular opening 13 is provided on the outer periphery of the drive rail 21. A first moving column 20 and a second moving column 12 are slidably connected inside the drive rail 21. A first support rod 14 extends into the drive rail 21 and is fixedly connected to the first moving column 20. The upper end of the second support rod 18 extends into the drive rail 21 and is fixedly connected to the second moving column 12. The drive rail 21 is composed of a smooth part, a first curved part 23 and two second curved parts 22, and the two curved parts are symmetrically arranged on the left and right.

[0034] With the above structure, when switching the state of the moving wheel 19 and the shock absorber 16, the rotating column 11 can be rotated by the rotating motor 10. When the shock absorber 16 needs to extend, the first curved part 23 is located directly below, the second moving column 12 is located inside the first curved part 23, and the second moving column 12 is located on the smooth part, so that the shock absorber 16 extends and the moving wheel 19 retracts. When the moving wheel 19 and the shock absorber 16 need to be fully retracted into the support leg 2, the first moving column 20 and the second moving column 12 can be located in the two second curved parts 22 respectively. When the moving wheel 19 and the shock absorber 16 need to be fully extended out of the support leg 2, the first moving column 20 and the second moving column 12 can be located on the smooth part. This structure can achieve switching between multiple states by rotating the rotating column 11. It is simple in structure, convenient in operation, and highly practical.

[0035] The working principle of this utility model is as follows: During operation, the raw material sheet is placed in the placement box 3. The height of the push block 9 is lower than the thickness of the raw material sheet. The drive motor 8 is turned on. The distance between the two push blocks 9 is greater than the length of the raw material sheet. The drive motor 8 drives the conveyor belt 7 to rotate through the drive roller. The conveyor belt 7 drives the push block 9 to move. The push block 9 can push the bottom raw material sheet away from the bottom of the placement box 3, so that the raw material sheet can move on the conveyor roller 5. When the raw material sheet leaves the placement box 3, the next raw material sheet in the placement box 3 will automatically fall onto the conveyor roller 5 under the action of gravity. The movement stability is high and there will be no relative sliding with the conveyor roller 5, which ensures the stability of sawing. At the same time, multiple push blocks 9 are provided, which can convey multiple raw material sheets at the same time to achieve continuous feeding. The drive mechanism can be used to retract the moving wheel 19 into the support leg 2, while the shock absorber 16 can be extended out of the support leg 2. The shock absorber 16 can be used to dampen and buffer the vibration generated during operation, thus extending the service life of the device. When moving, the moving wheel 19 can be extended to facilitate the movement of the device. When stored and not in operation, the moving wheel 19 and the shock absorber 16 can be completely retracted into the support leg 2 to prevent the moving wheel 19 and the shock absorber 16 from being subjected to pressure for a long time, thus extending their service life.

[0036] In summary, the continuous and stable conveying of raw material sheets is achieved through the design of mechanisms such as pusher block 9 and conveyor belt 7.
