[0001] The present invention relates to the technical field of feeding mechanical equipment, in particular to a feeding device. Background Art

[0002] When the feed port of a device or material processing apparatus is at a higher position, it is usually necessary to use a feeding device to transport the raw materials. In the related art, the feeding device usually uses a conveyor belt to transport the materials.

[0003] The above-mentioned related technical solutions have the following defects: when the production and subsequent processing of materials are in different workshops, after the material frame is transported to the subsequent processing workshop, the material needs to be dumped onto the conveyor belt. Manual operation is inevitably too laborious. If a flipping mechanism is added for dumping, the length of the loading device will be too long and the site area occupied will be too large. Summary of the Invention

[0004] In order to reduce the site occupied by the loading device, the present invention aims to provide a loading device.

[0005] The above-mentioned object of the present invention is achieved through the following technical solutions:

[0006] The lifting and flipping mechanism comprises a driving cylinder with a piston rod inclined upward, an end of the driving cylinder away from the piston rod and hinged to the bracket, the piston rod end of the driving cylinder is hinged to a push plate, the hinge shafts at both ends of the driving cylinder are arranged horizontally, a main shaft parallel to the hinge shaft of the driving cylinder is arranged between the two opposite side walls of the bracket, a flip plate is arranged on the side wall of the pushing plate, the flip plate is provided with two pieces and are respectively located on both sides of the flip plate, the two flip plates are connected to the main shaft, and a placement frame is provided between the ends of the two flip plates, and the driving cylinder can drive the pushing plate and the flip plate to rotate with the main shaft as the axis.

[0007] By adopting this technical solution, in the initial state, the worker places the material frame within the placement frame. The piston rod of the drive cylinder then pushes the push plate, causing the flip plate to rotate about the axis, simultaneously completing the flipping and lifting process, and directly dumping the material into the feed port of the subsequent processing equipment. Compared to the related art that combines a flip mechanism with a conveyor belt, this effectively reduces the site occupied by the loading device.

[0008] In a preferred example, the present invention can be further configured as follows: a load-bearing block is provided on the bracket, the upper end surface of the load-bearing block is inclined, and after the flip plate is reversed, the side wall of the push plate conflicts with the inclined surface of the load-bearing block.

[0009] By adopting the above technical solution, due to the large weight of the material, the main shaft bears the force during the turning and pouring processes. Through the arrangement of the load-bearing blocks, the weight of the material can be effectively borne, and the service life and safety of the feeding device can be improved.

[0010] In a preferred example of the present invention, it can be further configured that: the turning angle of the turning plate from the initial state to the state of contacting the load-bearing block is greater than 90°.

A third plate is provided on the side wall of the first plate, and one side of the third plate is provided as an inclined surface. The pushing plate is arranged on the inclined surface of the third plate.

[0011] By adopting the above technical solution, through the arrangement of the third plate, an included angle is formed between the pushing plate and the first plate, so as to ensure that the pushing plate can be in contact and cooperation with the load-bearing block after turning. The turning angle is greater than 90°, which is convenient for the material to be poured from the material box into the feed inlet of the subsequent equipment.

[0012] In a preferred example of the present invention, it can be further configured that: cover cylinders are provided on the two opposite side walls of the placement frame facing the two turning plates, and the piston rods of the two cover cylinders are jointly connected with a cover plate.

[0013] By adopting the above technical solution, by controlling the movement of the cover plate towards the material box through the cover cylinder, the cover plate can seal the opening of the material box, and the material can be effectively prevented from spilling during the turning process. When pouring is required, the piston rod of the cover cylinder is driven to extend, and the material can be poured out of the material box.

[0014] In a preferred example of the present invention, it can be further configured that: sliding plates are slidably connected to the two opposite side walls of the placement frame, the two cover cylinders are respectively arranged on the corresponding sliding plates, discharge cylinders are provided on the two turning plates, and the piston rods of the two discharge cylinders are connected to the corresponding sliding plates, and the telescopic directions of the piston rods of the cover cylinder and the discharge cylinder are perpendicular to each other.

[0015] By adopting the above technical solution, by controlling the sliding of the cover cylinder through the sliding plate, when the material box is being poured, the lower opening can be gradually opened first, improving the pouring efficiency.

[0016] In a preferred example of the present invention, it can be further configured that: the placement frame and the turning plate are connected by a fixing plate, the middle of the fixing plate is recessed to form a groove, limiting bars are arranged between the two opposite inner walls of the groove, and the sliding plate is slidably connected between the two limiting bars.

[0017] By adopting the above technical solution, through the arrangement of the limiting bars, the stability of the sliding plate during the sliding process can be effectively improved.

[0018] In a preferred embodiment, the present invention can be further configured as follows: A gap is left between the sliding plate and the placement frame, and the hose of the capping cylinder passes through the gap in the groove.

[0019] By adopting the above technical solution, passing the hose of the capping cylinder through the gap in the groove can limit and protect the hose, avoiding scattering during the flipping process or interference by other objects, thus preventing faults of the capping cylinder.

[0020] In a preferred embodiment, the present invention can be further configured as follows: The hoses of the capping cylinder and the feeding cylinder are fixed on the side walls of the two flipping plates close to each other. A number of through holes are provided on the flipping plates, and cable ties for fixing the hoses are arranged in the number of through holes.

[0021] By adopting the above technical solution, through the cooperation of the cable ties and the through holes, the hoses of the capping cylinder and the feeding cylinder can be well fixed and protected.

[0022] In a preferred embodiment, the present invention can be further configured as follows: A load-bearing block is provided on the bracket, the upper end surface of the load-bearing block is inclined, the side wall of the pushing plate after the flipping plate is reversed abuts against the inclined surface of the load-bearing block, a sensor is arranged in the inclined surface of the load-bearing block, the sensor is used to judge whether the flipping plate abuts against the load-bearing block, and a control console is arranged on one side of the bracket. The control console receives the sensor signal and controls the piston rods of the capping cylinder and the feeding cylinder to extend.

[0023] By adopting the above technical solution, controlling the activities of the piston rods of the capping cylinder and the feeding cylinder through the signal of the sensor can effectively improve the efficiency and the stability of the device operation.

[0024] In a preferred embodiment, the present invention can be further configured as follows: The sensor adopts a photosensitive sensor.

[0025] By adopting the above technical solution, when in the state of dumping materials, since the pushing plate will abut against the inclined surface of the load-bearing block, and the photosensitive sensor is arranged in the inclined surface. On the one hand, it can effectively prevent the sensor from being damaged. On the other hand, when the pushing plate abuts against the load-bearing block, the photosensitive sensor will lose the light source, and the signal transmission is also relatively accurate.

[0026] In summary, the present invention includes at least one of the following beneficial technical effects:

[0027] 1. In the initial state, the staff places the material frame in the placement frame, and then pushes the pushing plate through the piston rod of the driving cylinder, so that the flipping plate rotates around the rotating shaft, and at the same time completes the flipping and lifting process, and directly dumps the materials into the feeding port of the subsequent material processing equipment.

Detailed Embodiment

[0037] The following will further elaborate on the present invention in conjunction with the attached Figures 1-6 for a more detailed description.

[0038] Refer to Figure 1, A feeding device disclosed by the present invention includes a bracket 1. A lifting and flipping mechanism 3 is arranged inside the bracket 1. A number of protective plates 2 are arranged on both sides of the bracket 1 with respect to the lifting and flipping mechanism 3. A control console 4 is arranged on one side of the protective plate 2. An inlet 5 of the equipment for the next process is arranged on one side of the lifting and flipping mechanism 3.

[0039] Referring to Figure 1 , Figure 2 , the lifting and flipping mechanism 3 includes two mutually parallel driving cylinders 31. The piston rods of the two driving cylinders 31 are inclined upward. The end of the driving cylinder 31 facing away from the piston rod is hinged to the inner bottom wall of the bracket 1. The ends of the piston rods of the two driving cylinders 31 are jointly hinged to a pushing plate 32. The hinge axes of the driving cylinders 31 with the bracket 1 and the pushing plate 32 are all horizontally arranged and mutually parallel. Two flipping plates 33 are fixed on the side of the pushing plate 32 facing the driving cylinder 31. The two flipping plates 33 are respectively located at both ends of the pushing plate 32. A placing frame 34 is fixedly connected between the ends of the two flipping plates 33. The staff places the loaded material frame in the placing frame 34.

[0040] Referring to Figure 2 , Figure 3 , the flipping plate 33 includes a first plate 331 and a second plate 332 that are perpendicular to each other. In the initial state, the first plate 331 is horizontally arranged. A third plate 333 is connected to the side wall of the first plate 331. One side of the third plate 333 is set as an inclined surface. The pushing plate 32 is fixedly connected to this inclined surface. In order to reduce interference during flipping and increase the flipping angle, the end of the first plate 331 facing away from the second plate 332 is sequentially connected with a fourth plate 334 and a fifth plate 335. The fourth plate 334 is inclined. The fifth plate 335 is parallel to the first plate 331. Among them, the two fifth plates 335 are respectively fixedly connected to the two opposite side walls of the placing frame 34.

[0041] Referring to Figure 2 , Figure 3 , two bearing seats 6 are fixedly connected to the inner bottom wall of the bracket 1. A main shaft 35 is rotatably connected between the two bearing seats 6. The main shaft 35 is parallel to the hinge axes at both ends of the driving cylinder 31. The main shaft 35 vertically penetrates the two second plates 332 and is fixedly connected to them. Two load-bearing blocks 7 are also fixedly connected to the bottom inner wall of the bracket 1. The upper end surface of the load-bearing block 7 is inclined. This inclined surface is located on the side of the load-bearing block 7 facing the main shaft 35.

[0042] Referring to Figure 4 , the driving cylinder 31 drives the piston rod to push the pushing plate 32, so that the flipping plate 33 and the pushing plate 32 rotate around the main shaft 35 until the pushing plate 32 abuts and fits against the inclined surface of the load-bearing block 7. In the implementation of this application, the flipping angle of the flipping plate 33 from the initial state to the dumping state is 104°.

[0043] Referring toFigure 2 , Figure 3 , Figure 5 The placement frame 34 and the flip plate 33 are fixedly connected by a fixed plate 8. The middle portion of the fixed plate 8 is recessed and formed with a groove. The groove is located on the side of the fixed plate 8 facing the placement frame 34. A limit bar 9 is fixedly connected between the two opposing inner walls of the groove. A sliding plate 10 is slidably connected between the two limit bars 9. The sliding plate 10 slides along the length of the fifth plate 335.

[0044] A capping cylinder 11 is fixedly connected to the side of the sliding plate 10 facing away from the fifth plate 335. The pistons of the capping cylinders 11 on both sides of the placement frame 34 are fixedly connected to a cover plate 12. When a worker places a material frame into the placement frame 34, the piston rods of the capping cylinders 11 retract, causing the cover plates 12 to seal the opening of the material frame, preventing the material from spilling during the turning process.

[0045] Discharging cylinders 13 are fixedly connected to opposite side walls of the two fifth plates 335 , and piston rods of the two discharging cylinders 13 are fixedly connected to corresponding sliding plates 10 .

[0046] Reference Figure 2 , Figure 5 A gap is left between the sliding plate 10 and the discharge frame, and the hose of the capping cylinder 11 passes through the gap in the groove. The side walls of the fourth plate 334 and the fifth plate 335 are penetrated by a plurality of through holes 14. Ties are provided in the through holes 14 to secure the hoses of the capping cylinder 11 and the discharge cylinder 13. The hoses of the capping cylinder 11 and the discharge cylinder 13 are both fixed to the side walls of the two flip plates 33 that are close to each other.

[0047] Reference Figure 6 , grooves are provided on the inclined surfaces of the two load-bearing blocks 7, and photosensors 15 are installed in the grooves. By installing two photosensors 15, it is possible to avoid that when a single photosensor 15 is damaged, the device cannot work properly.

[0048] The implementation principle of this embodiment is:

[0049] In the initial state, the staff places the material frame containing the material in the placement frame 34. At this time, the piston rods of the covering cylinder 11 and the discharge cylinder 13 are in the extended state. By operating the control console 4, the piston rods of the covering cylinder 11 and the discharge cylinder 13 are controlled to retract, so that the cover plate 12 seals the opening of the material frame.

[0050] Meanwhile, the piston rods of the driving cylinders 31 extend synchronously, driving the pushing plate 32, the turning plate 33 and the placing frame 34 to rotate around the main shaft 35 until the pushing plate 32 fits against the inclined surface of the load-bearing block 7. Since the inclination angle is small in the initial stage of turning, the materials in the material box will not spill due to friction. Therefore, the piston rods of the covering cylinder 11, the discharging cylinder 13 and the driving cylinders 31 can extend and retract synchronously. When the angle at which spilling may occur is reached, the piston rods of the covering cylinder 11 and the discharging cylinder 13 have completed retraction.

[0051] After the pushing plate 32 and the load-bearing block 7 are in contact with each other, the photosensitive sensor 15 in the load-bearing block 7 loses the light source and sends a signal to the control console 4. The control console 4 processes the signal and controls the piston rods of the covering cylinder 11 and the discharging cylinder 13 to extend, thereby opening the cover plate 12 to pour the materials into the feeding port 5. By setting the time on the control console 4, after a preset time is reached starting from the moment when the photosensitive sensor 15 sends a signal of losing the light source, the control console 4 controls the piston rod of the driving rod to contract and reset, thereby driving the placing frame 34 back to its original position to wait for the next feeding operation.

[0052] The embodiments of this specific implementation manner are all preferred embodiments of the present invention, and do not limit the protection scope of the present invention accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present invention shall be covered within the protection scope of the present invention.
