Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, and more specifically, to a steel grating processing and conveying device. Background Technology

[0002] Steel grating, a type of mesh-like metal component made of load-bearing flat steel and twisted steel welded at a certain warp and weft spacing, is widely used in industrial platforms, trench covers, stair treads and other fields due to its advantages such as ventilation and light transmission, strong load-bearing capacity and anti-slip properties.

[0003] In practical applications, steel gratings need to be cut to the dimensions on site. First, they are unstacked, and then, to ensure safety, they are transported to the cutting equipment for length cutting via a conveyor.

[0004] However, during the conveying process, due to the inherent mesh structure of the steel grating, its contact with the conveying device (especially roller conveyors or belt conveyors) is discontinuous line contact or point contact, resulting in uneven friction and poor positioning. During acceleration, deceleration, or start-stop, the steel grating is prone to sliding, shifting, or deflecting on the conveying surface, thus deviating from the predetermined conveying trajectory and the final cutting positioning point. This requires operators to manually correct and reposition the steel grating, increasing labor intensity and resulting in low work efficiency.

[0005] Therefore, a steel grating processing and conveying device is proposed. Summary of the Invention

[0006] To address the problems existing in the prior art, the purpose of this invention is to provide a steel grating processing and conveying device that can ensure the steel grating maintains a specified posture during the conveying process, thereby eliminating the need for secondary straightening when the steel grating reaches the designated position and reducing the workload of workers.

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A steel grating processing and conveying device includes a frame;

[0009] The top wall of the frame is provided with an installation groove, and multiple rotating rollers are rotatably inserted on the side walls opposite to the installation groove. A motor with its output end fixedly connected to the rotating roller shaft is also fixedly installed on the side wall of the frame.

[0010] A telescopic rod is slidably installed on the side wall of the mounting groove, and the telescopic rod is parallel to the rotating roller;

[0011] A clamp is fixedly installed on the output end of the telescopic rod;

[0012] The rotating roller has a cylindrical cavity, and the side wall of the cavity has uniformly opened through holes that communicate with the outside.

[0013] A round hole is provided on the end face of the cavity;

[0014] The first grooves are evenly distributed on the side wall of the circular hole. The first grooves are evenly distributed circumferentially on the side wall of the circular hole, and the extension lines of multiple first grooves intersect at the center of the circular hole.

[0015] Each first groove has a mounting rod slidably installed inside it. Each mounting rod has multiple balls movably embedded on the side near the through hole. The balls correspond one-to-one with the through holes. The cavity is equipped with a drive mechanism for driving the mounting rod to move along the first groove.

[0016] Furthermore, a strip-shaped second sliding groove is provided on the side wall of the mounting groove, and a slider is slidably installed in the second sliding groove. The telescopic rod is horizontally fixedly installed on the side wall of the slider.

[0017] A first magnet is embedded in the side wall of the slider, and a second magnet is fixedly installed on the side wall of the second groove. The first magnet and the second magnet repel each other.

[0018] Furthermore, the drive mechanism includes a slide plate slidably mounted in the cavity, and a first elastic element is installed between the slide plate and the end of the cavity away from the circular hole;

[0019] A push block with a tapered end is fixedly installed on the side wall of the slide plate near the mounting rod, with the tip of the push block pointing towards the round hole.

[0020] Furthermore, the skateboard is made of magnetic material, and a coil connected in series with the motor is fixedly installed on the frame;

[0021] An elastic rope is installed between the mounting rod and the end of the first slide near the round hole, and the elastic coefficient of the first elastic element is greater than the elastic coefficient of the elastic rope.

[0022] Furthermore, a third sliding groove is provided on the side wall of the clamping plate, the output end of the telescopic rod is slidably inserted into the third sliding groove, and a second elastic element is installed between the output end of the telescopic rod and the top wall of the third sliding groove.

[0023] Furthermore, the push block includes a round rod and a conical block, with the two ends of the round rod being fixedly connected to the conical block and the sliding plate, respectively.

[0024] Furthermore, a locking hole is provided on the side wall of the mounting rod, and the ball bearing is movably embedded in the locking hole;

[0025] Furthermore, a pressure relief hole communicating with the outside is provided on the side wall of the card hole;

[0026] Each card hole has an air hole on its side wall that communicates with the guide groove; the rotating roller has an annular cavity, and the side wall of the annular cavity has guide grooves evenly distributed.

[0027] Furthermore, the rotating roller is equipped with an air supply mechanism for supplying air to the annular cavity.

[0028] Furthermore, the first elastic element is made of an elastic material;

[0029] The gas supply mechanism includes a pressurization chamber formed on the first elastic member, and an air inlet valve and an air outlet valve are respectively embedded in the side wall of the pressurization chamber;

[0030] The input end of the air intake valve passes through the side wall of the rotating roller and is connected to the outside.

[0031] The output end of the exhaust valve passes through the slide plate and push block and extends into the annular cavity.

[0032] Furthermore, the sidewalls of the pusher are mirrored, and the pusher is made of stainless steel.

[0033] Furthermore, both the top and bottom walls of the slider are provided with strip grooves, which are parallel to the first sliding groove.

[0034] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0035] (1) This solution utilizes the cooperation of clamps, telescopic rods, and ball bearings. For steel gratings with surface holes smaller than the diameter of the ball bearings: when steel gratings need to be transported, the unstacked steel gratings are placed on the surface of the rotating rollers, and then the telescopic rods are extended, thereby driving the two clamps to move closer to each other. The two clamps clamp the steel gratings, and when the steel gratings are aligned and clamped, the steel gratings can directly contact the ball bearings, thereby reducing the friction on the steel gratings during the alignment process and preventing wear on the surface of the steel gratings. When the output ends of both telescopic rods extend to the specified length, the steel gratings can be aligned. Then the motor is started, the ball bearings retract into the cavity, and the steel grating comes into contact with the rotating roller. When the rotating roller moves the steel grating through friction, the clamping plate moves with the steel grating. Thus, during the process of the rotating roller rotating and moving the steel grating, the clamping plate can clamp the steel grating, preventing the steel grating from shaking on the surface of the rotating roller, ensuring that the steel grating can be transferred to the designated position without secondary alignment, which improves work efficiency.

[0036] (2) In this scheme, through the cooperation of the third slide and the second elastic element, during the process of the clamping plate being aligned and clamping the steel grating, the steel grating is in contact with the ball bearings, and the second elastic element is in a relaxed state. When the motor is started and the ball bearings retract into the cavity, the steel grating falls onto the surface of the rotating roller under the action of the steel grating's gravity, and the clamping plate moves down with the steel grating. The second elastic element is in a stretched state, which ensures that the clamped steel grating can contact the rotating roller, thereby improving the stability during the conveying process.

[0037] (3) This solution utilizes the cooperation between the pressure relief hole and the air supply mechanism. Since dust is generated during the cutting of the steel grating, the gas discharged from the pressurized chamber through the pressure relief hole on the side wall of the chuck located on the bottom wall of the rotating roller is discharged to the outside. During the exhaust process of the pressure relief hole, the dust in the chuck is discharged to the outside along with the airflow, thereby reducing the resistance encountered by the ball when it rotates. This ensures that the steel grating can rotate smoothly when the clamping plate straightens the steel grating, thus ensuring that the steel grating can be straightened. Attached Figure Description

[0047] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0048] Example 1:

[0049] Please see Figures 1 to 7 A steel grating processing and conveying device, comprising a frame 1;

[0050] The top wall of the frame 1 is provided with an installation groove, and multiple rotating rollers 2 are rotatably inserted on the side walls opposite to the installation groove. The multiple rotating rollers 2 are evenly distributed, and a motor 3 with its output end fixedly connected to the rotating shaft of the rotating roller 2 is fixedly installed on the side wall of the frame 1. Thus, the rotating roller 2 can be driven to rotate by the motor 3. When the material is placed on the surface of the rotating roller 2, the material can be moved by the rotating roller 2.

[0051] A telescopic rod 4 is slidably installed on the side wall of the mounting groove, and the telescopic rod 4 is parallel to the rotating roller 2;

[0052] A clamping plate 5 is fixedly installed on the output end of the telescopic rod 4;

[0053] A cylindrical cavity 6 is provided on the rotating roller 2, and through holes 7 communicating with the outside are evenly provided on the side wall of the cavity 6.

[0054] A circular hole 8 is provided on the end face of cavity 6;

[0055] The sidewall of the circular hole 8 is evenly provided with first grooves 9. The first grooves 9 are evenly distributed circumferentially on the sidewall of the circular hole 8, and the extension lines of multiple first grooves 9 intersect at the center of the circular hole 8.

[0056] Each first groove 9 has a mounting rod 10 slidably installed in it. Each mounting rod 10 has multiple balls 11 movably embedded on the side near the through hole 7. The balls 11 correspond one-to-one with the through holes 7. The cavity 6 is provided with a drive mechanism for driving the mounting rod 10 to move along the first groove 9.

[0057] like Figure 2 As shown, a strip-shaped second sliding groove 12 is provided on the side wall of the mounting groove. The second sliding groove 12 penetrates the side wall of the frame 1. A slider 13 is slidably installed in the second sliding groove 12. The telescopic rod 4 is horizontally fixedly installed on the side wall of the slider 13.

[0058] A first magnet 14 is embedded in the side wall of the slider 13, and a second magnet 15 is fixedly installed on the side wall of the second slide groove 12. The first magnet 14 and the second magnet 15 repel each other, and the second magnet 15 is located at the end of the second slide groove 12 near the cutting station.

[0059] like Figure 5 As shown, the drive mechanism includes a slide plate 16 that is slidably installed in the cavity 6, and a first elastic element 17 is installed between the slide plate 16 and the end of the cavity 6 away from the circular hole 8.

[0060] A push block 18 with a tapered end is fixedly installed on the side wall of the slide plate 16 near the mounting rod 10, with the tip of the push block 18 pointing towards the round hole 8.

[0061] like Figure 4 , Figure 5 As shown, the skateboard 16 is made of magnetic material. A coil 19 connected in series with the motor 3 is fixedly installed on the frame 1. When the motor 3 is energized, a magnetic field is generated around the coil 19. The adjacent ends of the coil 19 and the skateboard 16 are opposite magnetic poles. Therefore, when the motor 3 is energized, the skateboard 16 is attracted by an attractive force.

[0062] An elastic rope 20 is installed between the mounting rod 10 and the end of the first sliding groove 9 near the round hole 8, and the elastic coefficient of the first elastic element 17 is greater than the elastic coefficient of the elastic rope 20.

[0063] When the motor 3 is not powered on, the first elastic element 17 does not deform. At this time, under the action of the first elastic element 17, the push block 18 is inserted between multiple mounting rods 10, the side wall of the mounting rod 10 is in contact with the side wall of the cavity 6, the elastic rope 20 is in a stretched state, and the ball 11 extends to the outside of the through hole 7.

[0064] When the motor 3 is powered on, a magnetic field is generated around the coil 19 that attracts the slide plate 16. Under the action of the attraction, the slide plate 16 drives the push block 18 to be pulled out from between the multiple mounting rods 10, and the first elastic element 17 is squeezed. At the same time, the elastic rope 20 pulls the mounting rod 10 closer to the round hole 8 until the ball 11 retracts into the cavity 6.

[0065] like Figure 7 As shown, a third sliding groove 21 is provided on the side wall of the clamping plate 5, the output end of the telescopic rod 4 is slidably inserted into the third sliding groove 21, and a second elastic element 22 is installed between the output end of the telescopic rod 4 and the top wall of the third sliding groove 21.

[0066] During the process of aligning and clamping the steel grating with the clamping plate 5, the steel grating comes into contact with the ball bearing 11, and the second elastic element 22 is in a relaxed state.

[0067] When the motor 3 is started and the ball bearing 11 retracts into the cavity 6, the steel grating falls onto the surface of the rotating roller 2 under the action of its own weight, and the clamping plate 5 moves down with the steel grating. The second elastic element 22 is in a stretched state, which ensures that the clamped steel grating can contact the rotating roller 2.

[0068] In the initial state, the telescopic rod 4 is in the retracted state, and the clamping plate 5 is located in the second slide groove 12. At this time, under the action of the repulsive force between the first magnet 14 and the second magnet 15, the clamping plate 5 is located at the end of the second slide groove 12 away from the cutting station.

[0069] For steel gratings with surface holes smaller than the diameter of ball bearing 11: When it is necessary to transport the steel grating, firstly, the motor 3 is de-energized, and at this time the ball bearing 11 is in the state of extending out of the through hole 7.

[0070] The destacking steel grating is then placed on the surface of the rotating roller 2. The telescopic rod 4 is then extended, causing the two clamping plates 5 to move closer together, clamping the steel grating. During the alignment and clamping process, the clamping plates 5 ensure direct contact between the steel grating and the ball bearings 11, reducing friction and preventing surface wear. The steel grating is aligned when both telescopic rods 4 have extended to the specified length.

[0071] Then start motor 3, the ball bearing 11 retracts into cavity 6, and the steel grating comes into contact with rotating roller 2.

[0072] When the rotating roller 2 drives the steel grating to move through friction, the clamping plate 5 moves along with the steel grating.

[0073] When the rotating roller 2 moves the steel grating to the designated position, the telescopic rod 4 is retracted. At this time, the clamping plate 5 moves the first magnet 14 closer to the second magnet 15. When the clamping plate 5 retracts into the second slide groove 12, under the action of the repulsive force between the first magnet 14 and the second magnet 15, the first magnet 14 moves the clamping plate 5 and the slider 13 to the end of the second slide groove 12 away from the cutting station, in preparation for working again.

[0074] Thus, as the rotating roller 2 rotates and drives the steel grating to move, the clamping plate 5 can clamp the steel grating, preventing it from shaking on the surface of the rotating roller 2, ensuring that the steel grating can be transferred to the designated position without secondary straightening, thereby improving work efficiency.

[0075] like Figure 5As shown, the push block 18 includes a round rod 1802 and a conical block 1801. The two ends of the round rod 1802 are fixedly connected to the conical block 1801 and the slide plate 16, respectively. Therefore, when the push block 18 moves toward the round hole 8, the conical block 1801 is first inserted between multiple mounting plates, and then the round rod 1802 is inserted between multiple mounting rods 10. The round rod 1802 provides support force to the mounting plate. When the steel grating is placed on the surface of the ball 11, it plays a role in preventing the ball 11 from retracting into the cavity 6.

[0076] like Figure 6 As shown, a locking hole 23 is provided on the side wall of the mounting rod 10, and the ball bearing 11 is movably embedded in the locking hole 23;

[0077] Furthermore, a pressure relief hole 24 communicating with the outside is provided on the side wall of the card hole 23;

[0078] Each card hole 23 has an air hole 25 on its side wall that communicates with the guide groove 27; the rotating roller 2 has an annular cavity 26, and the side wall of the annular cavity 26 is uniformly provided with guide grooves 27.

[0079] Furthermore, the rotating roller 2 is equipped with an air supply mechanism for supplying air to the annular cavity 26.

[0080] The first elastic element 17 is made of elastic material;

[0081] The gas supply mechanism includes a pressurization chamber 28 opened on the first elastic member 17, and an air inlet valve 29 and an air outlet valve 30 are respectively embedded on the side wall of the pressurization chamber 28.

[0082] The input end of the air intake valve 29 passes through the side wall of the rotating roller 2 and is connected to the outside.

[0083] The output end of the exhaust valve 30 passes through the slide plate 16 and the push block 18 and extends into the annular cavity 26.

[0084] When the motor 3 is de-energized, the first elastic element 17 is squeezed. At this time, the gas in the pressurized chamber 28 is discharged into the annular chamber 26 through the exhaust valve 30, and then discharged into the card hole 23 through the guide groove 27 and the air hole 25. Finally, it is discharged through the gap between the card hole 23 and the side wall of the ball 11 and the pressure relief hole 24.

[0085] Since dust is generated when cutting steel grating, the gas discharged from the pressurized chamber 28 is released to the outside through the pressure relief hole 24 on the side wall of the 23 located on the bottom wall of the rotating roller 2.

[0086] During the venting process of the pressure relief hole 24, the dust in the clamp hole 23 is discharged to the outside along with the airflow, thereby reducing the resistance encountered by the ball 11 when it rotates. This ensures that the steel grating can rotate smoothly when the clamp plate 5 straightens the steel grating, thus ensuring that the steel grating can be straightened.

[0087] like Figure 5 As shown, the sidewall of the push block 18 is mirrored and the push block 18 is made of stainless steel. By setting the sidewall of the push block 18 to be mirrored, the friction between the push block 18 and the mounting rod 10 can be reduced. When the push block 18 pushes the mounting rod 10 to move along the first slide groove 9, it plays a role in ensuring that the mounting rod 10 can move smoothly.

[0088] like Figure 7 As shown, both the top and bottom walls of the slider 13 are provided with strip grooves 31, which are parallel to the first sliding groove 9. This reduces the friction between the slider 13 and the first sliding groove 9, ensuring that the slider 13 can be reset under the repulsive force between the first magnet 14 and the second magnet 15.

[0089] Instructions for use: When steel grating needs to be conveyed, firstly, the motor 3 is de-energized, and at this time the ball bearing 11 is in the state of extending out of the through hole 7.

[0090] The destacking steel grating is then placed on the surface of the rotating roller 2. The telescopic rod 4 is then extended, causing the two clamping plates 5 to move closer together, clamping the steel grating. During the alignment and clamping process, the clamping plates 5 ensure direct contact between the steel grating and the ball bearings 11, reducing friction and preventing surface wear. The steel grating is aligned when both telescopic rods 4 have extended to the specified length.

[0091] Then start motor 3, the ball bearing 11 retracts into cavity 6, and the steel grating comes into contact with rotating roller 2.

[0092] When the rotating roller 2 drives the steel grating to move through friction, the clamping plate 5 moves along with the steel grating.

[0093] When the rotating roller 2 moves the steel grating to the designated position, the telescopic rod 4 is retracted. At this time, the clamping plate 5 moves the first magnet 14 closer to the second magnet 15. When the clamping plate 5 retracts into the second slide groove 12, under the action of the repulsive force between the first magnet 14 and the second magnet 15, the first magnet 14 moves the clamping plate 5 and the slider 13 to the end of the second slide groove 12 away from the cutting station, in preparation for working again.

[0094] Thus, as the rotating roller 2 rotates and drives the steel grating to move, the clamping plate 5 can clamp the steel grating, preventing it from shaking on the surface of the rotating roller 2, ensuring that the steel grating can be transferred to the designated position without secondary straightening, thereby improving work efficiency.

[0095] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
