Description

Technical Field

[0001] This utility model relates to the field of profile stacking technology, specifically a profile stacking device. Background Technology

[0002] Previously, palletizing and packaging of steel profiles were mostly done manually. For new products such as large-size and long-length profiles, manual palletizing is difficult to implement, and it cannot guarantee product packaging quality. Furthermore, manual methods result in high labor intensity for workers, and the increase in production capacity is limited by human capabilities. Worker safety is also poor, with numerous safety hazards that can easily lead to accidents. Therefore, specialized automated machinery for palletizing steel profiles is needed. However, current steel profile palletizing devices lack anti-fall functionality, causing steel profiles to easily fall during the palletizing process. To address these shortcomings, existing technology (Chinese patent application number: 202322907552.8, authorized announcement date: 2024-06-07) discloses a steel... The profile palletizing device uses a palletizer body and clamping plates to hold steel profiles. The baffles prevent the profiles from falling and injuring workers during clamping. A first motor drives a threaded rod to rotate, and with the cooperation of a threaded sleeve, slider, and groove, the horizontal position of the palletizer body can be adjusted, facilitating pallet placement. When it's time to lower a steel profile, a second motor rotates 180 degrees, disengaging the baffles and allowing for easy placement. A pressure sensor detects the pressure between the clamping plates and the steel profile, allowing for a further tightening of the palletizer body when the pressure decreases, thus improving the anti-falling effect.

[0003] Existing technology uses clamps to hold and fix steel profiles to prevent them from falling during stacking. However, excessive clamping force can easily cause indentations on the steel profiles, affecting product quality. Furthermore, while automatic stacking devices are also used in China, these devices mostly employ electromagnet translation and electromagnet oscillation to stack the steel profiles in opposite directions, resulting in low production efficiency. Therefore, we have proposed a profile stacking device that can effectively solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a profile stacking device to solve the problem mentioned in the background art, which is that excessive clamping force can easily cause indentations on steel profiles, thus affecting product quality. Furthermore, while there are existing automatic stacking devices in China, most domestic equipment uses electromagnet translation and electromagnet swing to stack the front and back steel profiles separately, resulting in low production efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a profile stacking device, comprising a base plate, wherein fixed plates are symmetrically fixed on the right side of the upper surface of the base plate, and a conveying roller is installed between the two fixed plates; a bracket is symmetrically fixed on the left side of the upper surface of the base plate, and a motor is installed on the left side of the top of the bracket; further comprising: a threaded rod rotatably connected to the top of the front bracket, a fixed rod fixedly connected to the top of the rear bracket, a threaded sleeve plate sleeved on the outer side of the fixed rod and the threaded rod, and a hydraulic cylinder installed on the top of the threaded sleeve plate; an electromagnet is provided below the threaded sleeve plate; a support block is fixed to the output end of the hydraulic cylinder, and a driven gear is rotatably connected to the inside of the support block via a shaft; and a rack is fixed to the front of the rear bracket.

[0006] Preferably, the threaded sleeve and the threaded rod are connected by a thread, and the threaded sleeve and the fixed rod are connected by a sliding connection. The output end of the hydraulic cylinder passes through the interior of the threaded sleeve, and the output end of the hydraulic cylinder is fixedly connected to the top of the support block by bolts.

[0007] Preferably, the top of the electromagnet is fixed with connecting blocks at equal angles, the shaft end of the driven gear is fixedly connected to the top of the electromagnet, the electromagnet is slidably disposed at the bottom of the support block through multiple connecting blocks, and the rack and the driven gear are meshed.

[0008] Preferably, a movable plate is hinged to the upper surface of the base plate, and movable blocks and partition plates are respectively provided on the left and right sides of the top of the movable plate, and a torsion spring is installed at the connection position between the shaft end of the movable plate and the base plate.

[0009] Preferably, both the partition plate and the movable block are hinged to the upper surface of the movable plate, the top of the movable block is arc-shaped, and the height of the movable block is higher than the height of the conveying roller.

[0010] Preferably, movable plates are fixed on both the front and rear sides of the threaded sleeve, and a fitting block is provided on the side of the bottom of the movable plate. Connecting plates are connected inside the two fixed plates, and adjusting plates are fixed at the opposite ends of the two connecting plates. A return spring is installed at the connection position between the outer side of the connecting plate and the fixed plate.

[0011] Preferably, the movable plate is arranged in an "L" shape, the connecting plate is slidably connected to the inside of the fixed plate, and both ends of the connecting plate extend out of the outer surface of the fixed plate. The opposite ends of the two connecting plates are inclined, and the outer side of the bonding block is in contact with the inclined surface of the connecting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This profile palletizing device adopts a novel structural design, the specific details of which are as follows:

[0013] (1) When the electromagnet moves the steel to the left, the rack makes the driven gear rotate and drives the electromagnet and the steel to rotate, thus adjusting the position of the steel. The electromagnet can be used to stack profiles and stack steel in both directions by rotating itself. This has the advantages of reducing labor intensity, improving production efficiency, reducing production costs, simple operation, high safety, and enabling multi-specification production.

[0014] (2) The threaded rod is driven by a motor to rotate, so that the threaded sleeve moves the electromagnet to the upper position of the steel. Then the hydraulic cylinder drives the electromagnet downward, so that the electromagnet is energized and attracts the steel, which can prevent the profile from being indented and ensure the quality of the profile. Then the motor drives the threaded rod to reverse, move the steel to the starting position, and drive the steel down through the hydraulic cylinder. At the same time, the electromagnet is de-energized and the steel is put down. The above operation is repeated to realize automatic stacking.

[0015] (3) The conveying roller moves the steel to the position of the movable block. The movable block moves downward under the weight of the steel itself. By using the lever principle, the movable plate rotates and drives the partition plate at the other end to move upward, which can block the steel behind it, thereby preventing the steel on the conveying roller from accumulating and blocking and affecting the stacking efficiency.

[0016] (4) When the threaded sleeve plate moves the electromagnet to the right, the moving plate moves to the position of the connecting plate and uses the sticking block to squeeze the connecting plate, causing the connecting plate to move. At this time, the two adjusting plates move relative to each other, centering the steel, so that the electromagnet can accurately adsorb the steel and ensure the stability in the stacking.

[0025] 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.

[0026] Please see Figures 1-7 The present invention provides the following technical solution: a profile stacking device;

[0027] Example 1: To address the issue that excessive clamping force in existing technologies can easily cause indentations on steel profiles, affecting product quality, and considering that while some domestic automatic stacking devices exist, their low production efficiency stems from the use of electromagnets 10 for translation and oscillation to stack the steel profiles in opposite directions, the following solution is disclosed. Please refer to the following for details. Figures 1-3 and Figure 5 As shown, the system includes a base plate 1, with fixed plates 2 symmetrically fixed on the right side of the upper surface of the base plate 1, and a conveyor roller 3 installed between the two fixed plates 2. Supports 4 are symmetrically fixed on the left side of the upper surface of the base plate 1, and a motor is installed on the left side of the top of the supports 4. The system also includes: a threaded rod 5 rotatably connected to the top of the front support 4, a fixed rod 6 fixedly connected to the top of the rear support 4, threaded sleeve plates 7 sleeved on the outer sides of the fixed rod 6 and the threaded rod 5, a hydraulic cylinder 8 installed on the top of the threaded sleeve plate 7, an electromagnet 10 below the threaded sleeve plate 7, and a support block 14 fixed to the output end of the hydraulic cylinder 8. The support block 14 is internally rotatable via a shaft. The driven gear 15 is dynamically connected, and the top of the electromagnet 10 is fixed with connecting blocks 16 at equal angles. The shaft end of the driven gear 15 is fixedly connected to the top of the electromagnet 10. The electromagnet 10 is slidably set at the bottom of the support block 14 through multiple connecting blocks 16. The rack 21 is meshed with the driven gear 15. The rack 21 is fixed on the front of the rear bracket 4. The threaded sleeve 7 is threadedly connected to the threaded rod 5, and the threaded sleeve 7 is slidably connected to the fixed rod 6. The output end of the hydraulic cylinder 8 passes through the interior of the threaded sleeve 7, and the output end of the hydraulic cylinder 8 is fixedly connected to the top of the support block 14 by bolts.

[0028] In operation, the steel is moved to the support position by the conveying roller 3, and the threaded rod 5 is rotated by the motor, causing the threaded sleeve 7 to move the electromagnet 10 to the upper position of the steel. Then, the hydraulic cylinder 8 drives the electromagnet 10 downward, so that the electromagnet 10 is energized and attracts the steel. Then, the motor drives the threaded rod 5 to reverse, moving the steel to the starting position, and the hydraulic cylinder 8 drives the steel to descend. At the same time, the electromagnet 10 is de-energized and the steel is put down. The above operation is repeated to achieve automatic stacking. Then, when the electromagnet 10 moves the steel to the left, the rack 21 causes the driven gear 15 to rotate, which in turn drives the electromagnet 10 and the steel to rotate, thus adjusting the position of the steel. In this way, the electromagnet 10 is used to achieve the stacking of profiles and the stacking of steel in both directions. It has the advantages of reducing labor intensity, improving production efficiency, reducing production costs, simple operation, high safety, and enabling multi-specification production.

[0029] Example 2: Unlike Example 1, this example utilizes the upward movement of the partition plate 12 to block subsequent steel materials, preventing the steel materials on the conveyor roller 3 from accumulating and clogging, thus affecting the stacking efficiency. See details... Figure 3 and Figure 4 As shown, a movable plate 11 is hinged to the upper surface of the base plate 1, and a movable block 13 and a partition plate 12 are respectively provided on the left and right sides of the top of the movable plate 11. A torsion spring is installed at the connection position between the shaft end of the movable plate 11 and the base plate 1. The partition plate 12 and the movable block 13 are both hinged to the upper surface of the movable plate 11. The top of the movable block 13 is set in an arc shape, and the height of the movable block 13 is higher than the height of the conveyor roller 3.

[0030] The conveyor roller 3 moves the steel to the position of the movable block 13. The movable block 13 moves downward under the weight of the steel itself, and by using the lever principle, the movable plate 11 rotates and drives the partition plate 12 at the other end to move upward, which can block the steel behind, thereby preventing the steel on the conveyor roller 3 from accumulating and blocking and affecting the stacking efficiency. When the steel is removed by the electromagnet 10, the movable plate 11 rotates and resets under the stored force of the torsion spring, causing the partition plate 12 to reset downward and no longer block the subsequent steel.

[0031] Example 3: Unlike Example 2, this example utilizes the relative movement of two adjusting plates 19 to center the steel, facilitating precise adsorption of the steel by the electromagnet 10 and ensuring stability during stacking. See details for further information. Figures 1-3 and Figure 6 and Figure 7As shown, movable plates 9 are fixed on both the front and rear sides of the threaded sleeve 7, and a fitting block 17 is provided on the side of the bottom of the movable plate 9. Connecting plates 18 are connected inside the two fixed plates 2, and adjusting plates 19 are fixed at the opposite ends of the two connecting plates 18. A return spring 20 is installed at the connection position between the outer side of the connecting plate 18 and the fixed plate 2. The movable plate 9 is L-shaped. The connecting plate 18 is slidably connected inside the fixed plate 2, and both ends of the connecting plate 18 extend out of the outer surface of the fixed plate 2. The opposite ends of the two connecting plates 18 are inclined. The outer side of the fitting block 17 is in contact with the inclined surface of the connecting plate 18.

[0032] When the threaded sleeve 7 moves the electromagnet 10 to the right, the moving plate 9 moves to the position of the connecting plate 18 and uses the contact block 17 to press the connecting plate 18, causing the connecting plate 18 to move. At this time, the two adjusting plates 19 move relative to each other, centering the steel, so that the electromagnet 10 can accurately attract the steel and ensure the stability in stacking. When the threaded sleeve 7 moves the moving plate 9 away from the connecting plate 18, the connecting plate 18 is reset under the elastic force of the return spring 20, and drives the adjusting plate 19 to reset.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
