Description

Technical Field

[0001] The invention relates to the technical field of steel grating plate edge wrapping equipment, in particular to an automatic edge wrapping mechanism for a steel grating plate. Background Art

[0002] Steel grating is an important industrial product in our current life and is widely used in many fields such as sewer manholes and fences. During the production process, the end faces of steel grating need to be welded to perform edging treatment. The welded plates are collectively referred to as edging plates.

[0003] An automatic edging mechanism for a steel grating plate with announcement number CN116197567B comprises a conveyor belt, and a feeding mechanism and a welding mechanism are arranged on both sides of the conveyor belt. The feeding mechanism comprises a support platform, and a lifting device capable of driving the support platform to rise and fall is arranged at the bottom of the support platform. A first limit block is arranged on one side of the support platform, and a second limit block is arranged on the support platform. The first limit block and the second limit block are arranged opposite to each other and the two form a groove for placing materials; a long groove is opened on the support platform, and the second limit block is located in the long groove. A first driving device is arranged on the support platform, and the first driving device drives the second limit block to move in the long groove and makes the second limit block close to or away from the first limit block. The second limit block is driven by the first driving device to approach the first limit block to narrow the groove, and the second limit block pushes the edging plate to move close to the first limit block, and the first limit block is located in the gap of the steel grating plate at this time, so the edging plate first contacts with the steel grating plate under the push of the second limit block, and at this time, the welding mechanism welds the edging plate and the steel grating plate together to realize the edging of the steel grating plate.

[0004] Although the above technical solution solves the problems of low efficiency and low precision of traditional manual welding, it is necessary to wrap the edges of the steel grating plate on all sides to improve the appearance and strengthen the structural strength of the steel grating plate. In the above technical solution, each time the steel grating plate passes through the welding area, both sides of the steel grating plate can be welded.

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] See also Figure 1-11 The present invention describes the above technical solution in detail through the following embodiments. An automatic edge binding mechanism for a steel grating plate includes a conveying platform 1, a lifting mechanism 2, a material box 3 and a welding mechanism 4. Lifting mechanisms 2 are provided on both sides of the conveying platform 1, and the lifting mechanisms 2 on both sides are connected by a rectangular lifting frame 5. Material boxes 3 are provided on the inner sides of the rectangular lifting frame 5, and welding mechanisms 4 are provided on the tops of the rectangular lifting frame 5. The welding mechanisms 4 reciprocate along the rectangular lifting frame 5.

[0046] The material box is used to stack and store multiple edging plates in a horizontal direction. A lower plate opening 6 communicating with the cavity is provided at the bottom of the material box 3. A material receiving plate 7 is provided below the lower plate opening 6. The material receiving plate 7 is connected to the material box 3 through abutment plates 8. A feeding mechanism 9 for moving the internal edging plates to the lower plate opening 6 is provided on the material box 3.

[0047] The abutment plate 8 is provided with a clearance hole 10, in which a transmission rod 11 is slidably inserted, and a push-pull mechanism 12 is provided on the rectangular lifting frame 5. A gripping plate mechanism 13 for grabbing the edge plate is provided at one end of the transmission rod 11, and the other end of the transmission rod 11 is connected to the push-pull mechanism 12;

[0048] The push-pull mechanism 12 around the rectangular lifting frame 5 pushes the edge plate to abut against the steel grating plate for welding by the welding mechanism 4, and the push-pull mechanism clamps and positions the steel grating plate by pushing the edge plate.

[0049] Specifically, after the steel grating plate on the conveying platform 1 is transported to the hemming area below the rectangular lifting frame 5, the lifting mechanism 2 drives the rectangular lifting frame 5 to descend, so that the hemming plate on the receiving plate 7 is aligned with the steel grating plate in height, and then the push-pull mechanism 12 around drives the transmission rod 11 to move the set distance to the steel plate grating, so that the steel grating plate is pushed to the specified position and clamped and positioned by the hemming plates around. At this time, the hemming plate is close to the steel grating plate, and the welding mechanisms 4 around begin to weld the hemming plate on the same side to the side of the steel grating plate. When the welding is completed, the gripping plate mechanism 13 is separated from the hemming plate, the push-pull mechanism 12 drives the transmission rod 11 and the gripping plate mechanism 13 to reset, and the lifting mechanism 2 drives the rectangular lifting frame 5 to rise, so that the steel grating plate on the conveying platform 1 leaves the hemming area. When the grab plate mechanism 13 is reset, the feeding mechanism 9 pushes the multiple edging plates in the material box 3 to move as a whole toward the lower plate opening 6, so that the frontmost edging plate moves above the lower plate opening 6 and falls onto the receiving plate 7 under the action of gravity. Then the grab plate mechanism 13 grabs the edging plate on the receiving plate 7 and waits for the next edging.

[0050] The present application arranges material boxes 3, feeding mechanisms 9, push-pull mechanisms 12, grabbing mechanisms 13 and welding mechanisms 4 around a rectangular lifting frame 5, and utilizes lifting mechanisms 2 on both sides of a conveying platform 1 to drive the rectangular lifting frame 5 to rise and fall, thereby being able to simultaneously perform edging on all sides of the steel grating plate transported by the conveying platform 1, thereby improving production efficiency and being able to meet the need for edging on all sides of the steel grating plate product.

[0051] The lifting mechanism 2 generally uses a hydraulic cylinder as a power component. Preferably, at least two hydraulic cylinders are provided on both sides of the conveying platform 1 to stably drive the rectangular lifting frame 5 to rise and fall.

[0052] Among them, the pushing and pulling mechanism 12 includes a rodless cylinder 1201 and a connecting rod 1202. The rodless cylinder 1201 is arranged on a rectangular lifting frame 5. The abutment plate 8 is provided with at least two make way holes 10. The rodless cylinder 1201 is connected to all the transmission rods 11 on the same side through the connecting rod 1202. By setting at least two transmission rods 11 for transmission, it is beneficial for the rodless cylinder 1201 to push the edging plate smoothly. The rodless cylinder 1201 is connected to the transmission rod 11 on the same side through the connecting rod 1202, which is beneficial to reducing the number of rodless cylinders 1201, or, when multiple rodless cylinders 1201 are used, it is beneficial to the centralized arrangement of multiple rodless cylinders 1201.

[0053] The gripping mechanism 13 includes a suction cup 1301 and a fixing seat 1302 . The suction cup 1301 is arranged at one end of the transmission rod 11 through the fixing seat 1302 . The transmission rod 11 and the fixing seat 1302 are provided with air holes 14 for connecting the suction cup 1301 with an external air source.

[0054] The lower end of the abutment plate 8 is tilted toward the lower plate opening 6 to help the edging plate on the receiving plate 7 to abut against the suction cup 1301 .

[0055] Correspondingly, the gripping plate mechanism 13 further includes a movable seat 1303 and a V-shaped spring sheet 1304, the suction cup 1301 is connected to the fixed seat 1302 via the movable seat 1303, an air cavity 15 connected to the suction cup 1301 is provided in the movable seat 1303, and hollow shafts 16 connected to the air cavity 15 are provided at both ends of the top of the movable seat 1303;

[0056] The movable seat 1303 is rotatably disposed on the fixed seat 1302 via the hollow shaft 16 and communicates with the air hole 14 inside the fixed seat 1302 via the hollow shaft 16. The V-shaped spring sheet 1304 connects the fixed seat 1302 and the movable seat 1303 and is located between the fixed seat 1302 and the movable seat 1303.

[0057] The suction cup 1301 is kept at the same inclination angle as the abutment plate 8 by the V-shaped spring sheet 1304, and the V-shaped spring sheet 1304 is compressed in the process of the edge plate pushing the steel grating plate until the edge plate fits against the side of the steel grating plate.

[0058] Moreover, in the process of the edging plate being abutted against the steel grating plate, the edging plate changes from inclined to vertical, and the height of the bottom of the edging plate decreases, thereby avoiding the problem of the bottom of the edging plate being higher than the bottom of the steel grating plate due to the presence of the receiving plate 7, resulting in poor edging effect.

[0059] In addition, to facilitate the fit between the movable seat 1303 and the fixed seat 1302, the V-shaped spring piece 1304 is preferably embedded in both, such as a groove structure for embedding the V-shaped spring piece 1304 on one side of the fixed seat 1302 and the movable seat 1303 that is close to each other.

[0060] The feeding mechanism 9 includes an upper rack 901, a lower rack 902, a transmission gear 903 and a transmission sleeve 904. A guide hole 17 is provided on one side of the material box 3 close to the rectangular lifting frame 5. The upper rack 901 is slidably plugged into the guide hole 17. The transmission gear 903 is rotatably arranged on the material box 3. The lower rack 902 is arranged on the transmission rod 11 through the transmission sleeve 904. The upper rack 901 and the lower rack 902 are connected by transmission through the transmission gear 903.

[0061] A slide groove 18 is axially provided on the side wall of the transmission rod 11, and a slider 19 connected to the transmission sleeve 904 is slidably provided in the slide groove 18. The slider 19 slides to one end of the slide groove 18 during the resetting process of the transmission rod 11, and pushes the lower rack 902 meshing with the transmission gear 903 to move under the drive of the transmission rod 11.

[0062] When the suction cup 1301 is reset, after the slider 19 moves relatively to the front end of the chute 18, as the transmission rod 11 drives the suction cup 1301 to continue to reset, the slider 19 drives the transmission sleeve 904 provided with the lower rack 902 to move backward, and under the transmission of the transmission gear 903, the upper rack 901 moves forward, so that when the suction cup 1301 is reset, the frontmost edge plate in the material box 3 moves to the lower plate opening 6 and falls onto the material receiving plate 7. At this time, the edge plate is located in front of the suction cup 1301 and abuts against the abutment plate 8 and the inclined plate. When the transmission rod 11 pushes the edge plate to move toward the steel grid plate, the slider 19 moves relatively backward along the chute 18 to avoid the transmission sleeve 904 from limiting the movement of the transmission rod 11. In this process, because the slider 19 loses support in the horizontal direction, it is impossible or difficult to push the lower rack 902 to move.

[0063] This embodiment not only realizes the coordination of the feeding mechanism 9 and the transmission rod 11 , but also reduces the use of driving components, which is beneficial to reduce the hardware cost and the load of the rectangular lifting frame 5 , thereby reducing the energy consumption of the lifting mechanism 2 .

[0064] Furthermore, in order to prevent the upper rack 901 from retreating due to mechanical vibration or the like, thereby affecting the supply of the next edging board, a pawl 20 is rotatably provided on the rectangular lifting frame 5, and a reverse tooth 21 is provided on the top of the upper rack 901. The tip of the pawl 20 is inserted into the tooth groove of the adjacent reverse tooth 21 to prevent the upper rack 901 from retreating.

[0065] The back of the material box 3 is connected to the rectangular lifting frame 5 , and the rectangular lifting frame 5 is provided with a clearance groove 22 at the upper rack 901 and the transmission gear 903 , so as to avoid assembly conflict between the rectangular lifting frame 5 and the material box 3 provided with the feeding mechanism 9 .

[0066] In addition, a mounting hole 23 connected to the clearance groove 22 is provided on the top of the rectangular lifting frame 5, and the pawl 20 is rotatably arranged in the mounting hole 23 through a pin shaft, so as to reduce the length of the pawl 20, and a reset handle 24 is provided at one end of the pawl 20 away from the upper rack 901, so as to operate the pawl 20 to separate from the inverted tooth 21. That is, before the hemming plate is loaded into the material box 3, the reset handle 24 is pressed downward to lift the pawl 20 and separate from the inverted tooth 21, and then the upper rack 901 is pulled to reset.

[0067] Among them, the welding mechanism 4 includes a linear guide rail 401 and a welding machine 402. The welding machine 402 is set on the top of the rectangular lifting frame 5 through the linear guide rail 401 and is driven by the linear guide rail 401 to reciprocate. During the movement, the welding machine 402 welds the edging plate and the steel grating plate on the same side.

[0068] Further optimized in the above embodiment is that a gate plate 25 is provided in the material box 3 to slide along the pushing direction of the edge plate, and a plurality of spring plungers 26 are provided on the side of the material box 3 close to the lower plate opening 6. The spring plungers 26 are connected to the gate plate 25 and limit the initial position of the gate plate 25 to be above the lower plate opening 6. When the upper rack 901 pushes the multiple edge plates inside the material box 3 to move as a whole, the edge plate at the front pushes the gate plate 25 to move above the lower plate opening 6, and in this process, the spring plunger 26 is compressed. Under the action of gravity, the edge plate above the lower plate opening 6 overcomes the friction between the gate plate 25 and falls onto the receiving plate 7.

[0069] In addition, a limit plate 27 is provided on the side of the material box 3 away from the lower plate opening 6, and the guide hole 17 passes through the limit plate 27. The side of the limit plate 27 and the gate plate 25 that are close to each other are both inclined surfaces with the same inclination angle as the abutment plate 8, which is conducive to the edging plate to be in a backward tilting posture when falling onto the receiving plate 7, so that the edging plate can be abutted against the abutment plate 8.

[0070] In addition, a feeding port 28 for adding edging boards is provided on the top of the material box 3. The feeding port 28 is located between the limiting plate 27 and the gate plate 25, so as to facilitate the addition of edging boards and indicate the area of ​​edging boards.

[0071] It is known from common technical knowledge that the present application can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present application or within the scope equivalent to the present application are included in the present application.
