Description

Technical Field

[0001] This utility model relates to the field of material lifting machine technology, specifically a material lifting machine. Background Technology

[0002] With the advancement of science and technology, machinery manufacturing and processing enterprises are also constantly developing and progressing, which has led to the upgrading and transformation of equipment. In the process of processing bar stock, it is necessary to transport the bar stock to machine tools or machines for processing. Instead, automated machine feeding devices are used, and even the feeding mechanism of bar stock has eliminated manual operation. The lifting machine is a mechanical device used to lift and transport materials. It is widely used in various processing fields to lift materials from a low place to a high place or to another position, which improves the feeding speed and avoids the damage caused by manual handling of materials. In the process of bar stock processing, lifting devices are also needed to transport the bar stock to a high place so that it can be moved to the next position for processing. However, during the use of the lifting machine, the outer surface of the bar stock will have residues left over from processing. These residues will gradually accumulate on the lifting machine during the lifting process and enter between the lifting components, thus causing the lifting machine to wear out faster. Utility Model Content

[0003] The purpose of this invention is to provide a material lifting machine to solve the problem mentioned in the background art that residue on the outer surface of the bar stock easily enters the material lifting machine, causing increased wear.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a material feeding machine, including a feeding rack, a square tube frame fixedly installed on one side surface of the feeding rack, and the square tube frame is a frame design, the outer surface of the feeding rack is inclined, and the end of the feeding rack near the square tube frame is the lowest point, a fixed base plate is fixedly installed inside the square tube frame, and the fixed base plate is connected to the square tube frame by screws, and a receiving mechanism is provided on the outer surface of the feeding rack, which allows the material bar to roll down more easily and reduces the probability of impurities accumulating on the outer surface of the material bar on the feeding rack.

[0005] Preferably, the receiving mechanism includes: a round steel rod, which is evenly arranged on the outer surface of the feeding rack, and a gap is left between the feeding rack and the round steel rod. A baffle plate is fixedly installed on the outer surface of the feeding rack. The baffle plate at one end of the feeding rack near the feeding port is lower than the baffle plate on the other side. The outer surface of the round steel rod is in contact with the outer surface of the material bar.

[0006] By adopting the above technical solution, the bar stock can be placed and stacked through the feeding rack, making it convenient for the bar stock to queue up and enter the lifting machine. The small contact area between the round steel rod and the bar stock allows the bar stock to roll more easily into the square tube frame. The gap between the round steel rods allows the residue to fall off when the bar stock rolls down and land at the bottom of the feeding rack. The baffle plate can effectively prevent the bar stock from falling off when it is stacked, reduce the amount of residue entering the lifting machine and causing wear, and extend the service life of the lifting machine.

[0007] Preferably, fixed side plates are fixedly installed on the outer surfaces of both ends of the fixed base plate, and the outer surfaces of the fixed side plates are provided with sliding grooves. A sliding pushing mechanism is provided between the fixed side plates and the fixed base plate, so that the material bar can be pushed up and lifted by the sliding pushing mechanism.

[0008] Using the above technical solution, after the hydraulic cylinder raises the mounting base, it can also raise the movable material plate together, so that the bar stock moves to the fixed material plate along the inclined surface of the feeding frame, and as the movable material plate rises, it lifts the bar stock one by one, allowing the bar stock to rise step by step.

[0009] Preferably, the sliding pushing mechanism includes: a movable side plate, the movable side plate being located on both sides of the fixed side plate, and a movable material plate being slidably installed in the groove of the fixed side plate, and the movable material plate being fixedly connected to the movable side plate; a fixed material plate being fixedly installed between the fixed side plates, and the outer surface of the fixed material plate being in contact with the outer surface of the movable material plate; a hydraulic cylinder being fixedly installed on the outer surface of the fixed base plate, and a mounting seat being fixedly installed at the output end of the hydraulic cylinder, and the mounting seat being connected to the movable material plate.

[0010] With the above technical solution, the hydraulic cylinder is set inside the square tube frame, which makes it easy to remove the hydraulic cylinder from the fixed base plate for replacement and repair after it is damaged. After the mounting seat is removed from the movable material plate, the movable material plate will also engage with the sliding groove of the fixed side plate, so that the movable material plate will not fall off.

[0011] Preferably, a sliding limiting mechanism is provided between the feeding rack and the movable side plate. The sliding limiting mechanism enables the movable side plate to run more stably and allows the movable material plate to move more smoothly.

[0012] By adopting the above technical solution, the movable side plate can move more smoothly and reduce the friction between the fixed plate and the movable plate, making the movable plate run more stably.

[0013] Preferably, the sliding limiting mechanism includes: a bearing mounting plate, which is fixedly installed on both sides of the square tube frame. A linear bearing seat is fixedly installed on one end of the bearing mounting plate near the movable side plate, and two pairs of guide rails are fixedly installed on the outer surface of the movable side plate. The guide rails engage with the linear bearing seat, and the linear bearing seat and the guide rails are slidably connected. The movable side plate does not adhere to the outer surface of the fixed side plate.

[0014] Using the above technical solution, when the hydraulic cylinder pushes a movable material plate to move, it will also bring the movable side plate to rise and slide together, so that the movable material plate can move upward at the same time and maintain the moving trajectory of the movable material plate. In addition, after the linear bearing seat is damaged, the bearing mounting plate can be removed to facilitate the replacement and maintenance of the linear bearing seat and guide rail.

[0015] Preferably, a photoelectric sensor is fixedly installed on the outer surface of the square tube frame away from the feeding rack, and a feeding extension plate is fixedly installed on the end of the square tube frame near the photoelectric sensor. The outer surface of the feeding extension plate below the photoelectric sensor has a through hole. Stop bars are fixedly installed on both outer surfaces of the feeding extension plate. An inclined support rod is provided between the feeding extension plate and the feeding rack, and the inclined support rod of the feeding extension plate does not contact the outer surface of the fixed material plate.

[0016] Using the above technical solution, after the bar stock is raised to the highest point, it will roll down the inclined surface of the fixed plate to the discharge extension plate. At this time, the photoelectric sensor will detect the bar stock passing through and count it. The baffle can effectively prevent the bar stock from rolling out of the discharge extension plate when it rolls down.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This material lifting machine:

[0018] 1. Simply place the bar stock prepared in the previous process onto the outer surface of the feeding rack, and the bar stock will roll down the inclined surface of the feeding rack. The bar stock will roll down to the top of the fixed material plate, and the round steel rod can effectively support the bar stock. During the rolling process, the impurities on the outer surface of the bar stock will not enter the interior of the lifting machine along the slope. The impurities will fall through the gaps in the round steel rod to the bottom of the feeding rack for easy cleaning. This reduces the wear caused by impurities entering the fixed material plate and the movable side plate, and improves the service life of the lifting machine.

[0019] 2. When the hydraulic cylinder is activated to retract and extend, it will move the mounting base and the movable material plate together. As the movable material plate moves, it will also raise and lower the movable side plate, allowing all the movable material plates to rise and fall together. Together with the fixed material plate, the material bar is lifted and transported to the designated location step by step. The linear bearing seats and guide rails on both sides of the movable side plate allow the movable material plate and the movable side plate to move vertically in a straight line, making the movement of the movable side plate and the movable material plate more stable. After the linear bearing seats and guide rails are worn and damaged, the bearing mounting plate can be removed to replace the linear bearing seats and guide rails, which can also reduce the wear caused by the movement between the movable material plate and the fixed material plate.

[0020] 3. After the bar stock is lifted to the highest point of the feeding machine, it will roll down the inclined surface of the fixed plate, allowing it to roll through the discharge extension plate. After the bar stock passes through the discharge extension plate, the photoelectric sensor will detect and count the passing bar stock, reducing the chance of material blockage in the next process. The baffle bar can effectively prevent the bar stock from falling off the discharge extension plate during the rolling process, while the support rod can increase the support force of the discharge extension plate, preventing the discharge extension plate from collapsing, counting the bar stock and preventing it from rolling off the discharge extension plate.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-6 This utility model provides a technical solution: a material feeding machine, including a feeding rack 1, a square tube frame 3 fixedly installed on one side surface of the feeding rack 1, and the square tube frame 3 is a frame design, the outer surface of the feeding rack 1 is inclined, and the end of the feeding rack 1 near the square tube frame 3 is the lowest point, a fixed base plate 4 is fixedly installed inside the square tube frame 3, and the fixed base plate 4 is connected to the square tube frame 3 by screws, and a receiving mechanism is provided on the outer surface of the feeding rack 1, which allows the material bar to roll down more easily and reduces the probability of impurities on the outer surface of the material bar accumulating on the feeding rack 1.

[0030] The bar stock processed in the previous process is neatly stacked on the outer surface of the feeding rack 1. The baffle plate 5 can prevent the bar stock from falling off the feeding rack 1 when it rolls down. The inclined design of the feeding rack 1 allows the bar stock to roll down automatically and enter the interior of the feeding rack 1, so that the bar stock can enter the fixed plate 7 for easy lifting.

[0031] The receiving mechanism includes: round steel rods 2, which are evenly arranged on the outer surface of the feeding rack 1, with a gap between the feeding rack 1 and the round steel rods 2. A baffle plate 5 is fixedly installed on the outer surface of the feeding rack 1. The baffle plate 5 at one end of the feeding rack 1 near the feeding port is lower than the baffle plate 5 on the other side. The outer surface of the round steel rods 2 is in contact with the outer surface of the material bar.

[0032] The small contact area between the round steel rod 2 and the bar stock effectively reduces friction during rolling. Furthermore, the gap between the round steel rods 2 allows residues adhering to the outer surface of the bar stock to fall out of the feeding rack 1, preventing residues from accumulating inside the feeding rack 1. This also prevents residues from entering between the fixed material plate 7 and the movable material plate 9 along the inclined surface of the feeding rack 1, thus avoiding increased wear and extending the service life of the lifting machine.

[0033] Fixed side plates 6 are fixedly installed on the outer surfaces of both ends of the fixed base plate 4, and the outer surface of the fixed side plates 6 is provided with sliding grooves. A sliding pushing mechanism is provided between the fixed side plates 6 and the fixed base plate 4, so that the material bar can be pushed up and lifted through the sliding pushing mechanism.

[0034] When the hydraulic cylinder 16 is damaged, it can be removed from the fixed base plate 4 and taken out from the side surface of the feeding rack 1 for easy replacement. When the hydraulic cylinder 16 and the mounting base 17 are removed, the movable material plate 9 will not fall directly to the bottom because of the sliding groove of the fixed side plate 6.

[0035] The sliding pushing mechanism includes: a movable side plate 8, which is located on both sides of the fixed side plate 6, and a movable material plate 9 is slidably installed in the groove of the fixed side plate 6, and the movable material plate 9 is fixedly connected to the movable side plate 8. A fixed material plate 7 is fixedly installed between the fixed side plates 6, and the outer surface of the fixed material plate 7 is in contact with the outer surface of the movable material plate 9. A hydraulic cylinder 16 is fixedly installed on the outer surface of the fixed base plate 4, and a mounting seat 17 is fixedly installed at the output end of the hydraulic cylinder 16, and the mounting seat 17 is connected to the movable material plate 9.

[0036] When the hydraulic cylinder 16 is activated, it will drive the mounting base 17 to rise together, causing the mounting base 17 to push the movable material plate 9 to move. This will push the bar material that reaches the top of the movable material plate 9 up and lift it onto the next fixed material plate 7, allowing the movable material plate 9 to move along the sliding groove direction of the fixed side plate 6. The bar material will then move along the inclined surface of the fixed material plate 7 to the next movable material plate 9, causing the hydraulic cylinder 16 to push the bar material upward as it extends and retracts.

[0037] A sliding limit mechanism is provided between the feeding rack 1 and the movable side plate 8. The sliding limit mechanism makes the movable side plate 8 run more stably and the movable material plate 9 move more smoothly.

[0038] By using two linear bearing seats 11 and two guide rails 12, the linear bearing seats 11 can move along the guide rails 12 when the movable side plate 8 moves, so that the movable side plate 8 can move stably and without deviation, reducing the contact between the movable material plate 9 and the fixed side plate 6, reducing the friction between the fixed side plate 6 and the movable material plate 9, and allowing the movable side plate 8 to move stably and smoothly.

[0039] The sliding limit mechanism includes: a bearing mounting plate 10, which is fixedly installed on both sides of the square tube frame 3. A linear bearing seat 11 is fixedly installed on one end of the bearing mounting plate 10 near the movable side plate 8. Two pairs of guide rails 12 are fixedly installed on the outer surface of the movable side plate 8. The guide rails 12 engage with the linear bearing seat 11, and the linear bearing seat 11 and the guide rails 12 are slidably connected. The movable side plate 8 is not in contact with the outer surface of the fixed side plate 6.

[0040] After the hydraulic cylinder 16 pushes the movable material plate 9, it will move along with the movable side plate 8, so that all the movable material plates 9 can rise and fall together, allowing the bar stock to be lifted and transported to the next processing and transportation location step by step. When the linear bearing seat 11 and the guide rail 12 are damaged or worn, the bearing mounting plate 10 can be removed, and the linear bearing seat 11 and the guide rail 12 can be repaired and replaced. At the same time, the fixed base plate 4 and the square tube frame 3 can be disassembled, and the fixed base plate 4 and the fixed side plate 6 can be removed as a whole, and the fixed material plate 7 and the movable material plate 9 can be repaired and replaced.

[0041] A photoelectric sensor 13 is fixedly installed on the outer surface of the square tube frame 3 away from the feeding rack 1. A feeding extension plate 14 is fixedly installed on the outer surface of the square tube frame 3 near the photoelectric sensor 13. A through hole is opened on the outer surface of the feeding extension plate 14 below the photoelectric sensor 13. A stop bar 15 is fixedly installed on both outer surfaces of the feeding extension plate 14. An inclined support rod is provided between the feeding extension plate 14 and the feeding rack 1. The inclined support rod of the feeding extension plate 14 does not contact the outer surface of the fixed material plate 7.

[0042] When the bar is pushed to the top, it will roll down along the feed plate 14. At this time, the photoelectric sensor 13 will detect the bar passing through and count it. The baffle 15 will prevent the bar from falling off the feed plate 14 while rolling, reducing the chance of the bar falling, and count the passing bars.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
