Description

Technical Field

[0002] The electromagnetic shielding waste container barrel is a container barrel used for storing waste and has an electromagnetic shielding function. The barrel body is made by bending the steel plate into the required steel plate coil by using a bending machine or a bending machine tool, and then the longitudinal seam is welded. The longitudinal seam can be directly welded by argon arc welding, or welding can be performed between the longitudinal seams by welding rods; however, the existing longitudinal seam welding device still has the following shortcomings during use: in order to improve the firmness, both the inner and outer sides of the longitudinal seam will be welded, but at this time it will require manual adjustment of the position of the steel plate coil, and the steel plate coil needs to be disassembled and assembled twice before and after welding, which increases the labor intensity.

At the same time, an elastic pad 48 can be fixedly installed on each clamping roller 27. The elasticity of the elastic pad 48 makes the clamping effect of the clamping roller 27 on the steel plate coil 30 better, while avoiding direct contact and improving the protection of each other.

This part is an existing conventional method and is not elaborated in detail here.

[0044] Reference Figure 1-Figure 12, a shaft is rotatably mounted on the support plate 3, a gear 2 34 meshing with the gear 1 7 is fixedly mounted on the shaft, a reciprocating screw 2 53 is fixedly mounted on one end of the shaft through a telescopic frame 35, and a support block 2 52 matching the reciprocating screw 2 53 is fixedly mounted on the moving block 13 mounted with the support block 16; the telescopic frame 35 is composed of two blocks, and the end faces of the two blocks are square in shape, and the two blocks can slide against each other and have a telescopic function; a ball nut 2 is mounted on the reciprocating screw 2 53, and a strip rod is mounted on the ball nut 2 36, two strip racks 37 are fixedly installed on the strip rod 36, and transmission gears 38 matched with the strip racks 37 are fixedly installed on the two reciprocating screws 22.

[0045] Reference Figure 1-Figure 12 , a plurality of slide grooves 40 are provided on the arc support plate 24. For ease of understanding, three slide grooves 40 are used for illustration. At this time, the slide groove 40 located in the middle position is only opened on the front side, and the upper ends and front sides of the other two slide grooves 40 are open.

[0046] An arc-shaped baffle plate 43 is installed on the outer movable block 13 in a detachable fixed manner. The specific installation method can be as follows: two clamping blocks 45 are fixedly installed on the outer side of the movable block 13, and three clamping plates 44 are fixedly installed on the lower end of the arc-shaped baffle plate 43. The two clamping plates 44 on both sides are provided with positioning clamping holes that match the clamping blocks 45, and the clamping plate 44 in the middle position is provided with a circular hole. A screw rod 46 that matches the circular hole is fixedly installed on the outer side of the movable block 13, and one end of the screw rod 46 passes through the circular hole and is threadedly installed with a nut 47.

[0047] The following points should be noted in the above summary:

[0048] 1. The shape of the swivel 8 is affected by the shape and position of the gas supply system 4 and the welding gun 5. Therefore, the middle position of the swivel 8 needs to be hollow. Therefore, it needs to be driven by a rotatable gear 7 to rotate, and the L-shaped rod 54 also needs to drive the welding gun 5 to rotate.

[0049] When the swivel 8 rotates, the gear 2 34, the telescopic frame 35, the bar rod 36, the bar rack 37, the transmission gear 38, the reciprocating screw 22, and the lifting block 23 cooperate to realize the automatic adaptive adjustment of the height of the steel plate coil 30 in the vertical direction, so as to realize the simultaneous adjustment of the height of the steel plate coil 30 and the angle of the welding gun 5;

[0050] The function of setting the gear 2 34 is to cooperate with the gear 1 7 to play a transmission role, and it is also convenient to select an appropriate transmission ratio according to the needs, so that the steel plate coil 30 can be moved to the required position when the rotating ring 8 rotates 180° (or increases the rotation of an integer circle on the basis);

[0051] The arrangement of the strip rod 36 and the strip rack 37 is to better cooperate with the two reciprocating screws 22, so that both sides of the steel plate coil 30 are simultaneously subjected to upward or downward force, making the movement more precise. The strip rod 36 and the strip rack 37 can be integrally formed, or can be manufactured separately and then fixed;

[0052] Since the bar 36 moves in the horizontal direction, and the steel plate coil 30 needs to be controlled to move in the vertical direction, the bar rack 37, the reciprocating screw 22 and the lifting block 23 need to cooperate to complete the task smoothly.

[0053] The telescopic frame 35 is provided because the steel plate coil 30 itself will move in the horizontal direction during operation. Only in this way can the horizontal movement and the vertical movement of the steel plate coil 30 not affect each other.

[0054] 2. The welding auxiliary motor 14 is used as a power source. With the cooperation of the one-way bearing 1 55 and the one-way bearing 2 56, the steel plate coil 30 can be automatically clamped and moved in the horizontal direction by forward and reverse rotation.

[0055] The reciprocating screw rod 15 is arranged to cooperate with the one-way bearing 55 to drive the two moving blocks 13 to move in the horizontal direction at the same time, and the movement is specifically a reciprocating movement;

[0056] The support block 16 is fixed on both sides of the moving block 13 close to the air supply system 4, and supports the reciprocating screw 22 and the shaft 17. Due to the influence of the specific setting size and the specific installation position, the support block 16 is set on both sides of the moving block 13 instead of directly setting a longer moving block 13. At the same time, this setting also makes it unnecessary to set the size of the moving block 13 longer (along the width direction of the welding table 1), which can save the materials required for manufacturing the moving block 13;

[0057] The support block 18 is provided to support the rotation of the drum 19. The support block 18 may also be integrally formed with the support plate 3. However, for the convenience of better description, it is named separately, which is similar to the above-mentioned support block 16.

[0058] 3. The transmission structure 1 20 is set to meet the transmission requirements between the one-way bearing 1 55 and the rotating drum 19, and the transmission structure 2 33 is set to meet the coordinated use of the shaft body 17 and the shaft body 2 32. This setting is due to the fact that the horizontal and vertical positions of the shaft body 2 32 will change with the movement of the steel plate coil 30, so it cannot be directly used with the one-way bearing 1 55. At the same time, since the one-way bearing 1 55 and the shaft body 2 32 themselves also have different spatial positions, they are not in the same plane in the horizontal and vertical directions, so it is necessary to cooperate with the transmission structure 1 20, the transmission structure 2 33 and the corresponding structures to meet the use requirements;

[0059] The cooperation between the strip clamping rod 21 and the rotating drum 19 enables the strip clamping rod 21 to rotate together with the rotating drum 19, and the strip clamping rod 21 can also move relative to the rotating drum 19, and the movement is to meet the needs of the horizontal movement of the steel plate coil 30;

[0060] A plurality of strip clamping rods 21 are fixedly connected to one end of the shaft body 17 through a disc. The plurality of strip clamping rods 21 are arranged so that the rotating drum 19 can rotate better. The disc facilitates better fixation with the shaft body 17 and the strip clamping rods 21, and the disc can be integrally manufactured with the shaft body 17 or the plurality of strip clamping rods 21. For the convenience of better description, they are named separately here. At the same time, the strip clamping rods 21 are arranged on the outside of the support plate 3 to avoid contact with the welding machine body 2 when moving.

[0061] The lifting block 23 and the arc-shaped support plate 24 can be one component, and are named separately here for better understanding.

[0062] 4. The fixed roller 25 is provided to meet the needs of the multiple adjusting screws 26, and the clamping roller 27 is provided to clamp the steel coil 30 in multiple directions.

[0063] The setting of the adjusting gear 28 enables the corresponding adjusting rack 29 to directly drive the multiple adjusting screws 26 to rotate together when moving, and then drive the corresponding clamping rollers 27 to move together, so as to clamp the steel plate coil 30 as required;

[0064] The setting of the second shaft 32 plays the role of transmitting rotation. Through the cooperation of the transmission structure 2 33 and the shaft 17, the rotation of the shaft 17 can drive the second shaft 32 to rotate; at the same time, since the steel plate coil 30 will move in the vertical direction, the cooperation of the tensioning wheel 49 can effectively ensure that the transmission structure 2 33 is always in a tensioned state.

[0065] 5. The arc baffle 43 is provided to cooperate with the arc support plate 24 to drive the steel plate coil 30 to move in the horizontal direction, and the clamping plate 44, the clamping block 45 and the positioning clamping hole are for the purpose of facilitating the clamping, positioning and clamping installation of the arc baffle 43 on the corresponding moving block 13. The arc baffle 43 and the clamping plate 44 can be integrally formed and manufactured. For ease of understanding, separate naming is adopted here, and the positioning clamping hole is also for the purpose of facilitating a better understanding of the description required; the nut 47 is used to cooperate with the clamping plate 44 to meet the effect of positioning and clamping, and also makes the subsequent fixation easier;

[0066] The screw rod 46 and the nut 47 are provided to realize quick fixation after the arc baffle 43 is positioned and engaged, and the fixing operation is simple. The nut 47 can be directly installed after the positioning and engagement, and there is no need to apply a positioning force to the arc baffle 43 during the installation process;

[0067] The movable plate 57 is provided to enable the plurality of adjusting racks 29 to move together. The movable plate 57 and the plurality of adjusting racks 29 may also be named as a whole, but distinguishing the names is easier to understand.

[0068] 6. The step chute 1 and the step slider 1 9 used in combination are normal settings that meet the rotation setting of the swivel 8, and the step-shaped setting allows the swivel 8 to rotate without moving away from the support plate 3;

[0069] The cooperation between the second step slide groove 11 and the second step slider 12 is a common setting to meet the normal movement of the moving block 13 on the welding table 1, and the step-shaped setting enables the moving block 13 to slide only on the welding table 1 without relative movement in the vertical direction.

[0070] The elastic pad 48 is provided to prevent the pressing roller 27 from directly contacting the inner wall of the steel plate coil 30, and at the same time, the elasticity of the elastic pad 48 can also make the clamping more secure;

[0071] The second slideway, the second slider 50 and the tension spring 51 are all required for the normal coordination 49 to ensure that the tension wheel 49 always tensions the second moving structure 33;

[0072] Since one end of the adjustment rack 29 passes through the arc support plate 24, a square hole 39 needs to be opened on the arc support plate 24 to meet the normal movement requirements of the adjustment rack 29. At the same time, the square hole 39 also supports the sliding of the adjustment rack 29.

[0073] The arrangement of the slide groove 40, the slider 41 and the connecting frame 42 serves to limit the movement of the corresponding pressing roller 27, and cooperates with the use of the adjusting gear 28 and the adjusting rack 29 to better realize the expansion and telescopic function.

[0074] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0075] In the present invention, the figure shows a schematic diagram of a steel coil 30, a welding rod 31 and an arc-shaped baffle 43 after they have been installed, and the description is based on this for ease of understanding;

[0076] Movement of the steel plate coil 30 and the welding rod 31 in the horizontal direction: the welding auxiliary motor 14 is turned on, and the welding auxiliary motor 14 drives the reciprocating screw rod 15 to rotate through the one-way bearing 55. The reciprocating screw rod 15 rotates and drives the two moving blocks 13 to move in the horizontal direction through the ball nut 1, and then the steel plate coil 30 and the welding rod 31 can be driven to move together. The welding rod 31 is clamped and pressed tightly by the steel plate coil 30. On the one hand, the steel plate coil 30 is pushed by the arc baffle 43, and on the other hand, it is pressed by multiple pressing rollers 27, so that it moves together;

[0077] The steel coil 30 and the welding rod 31 are welded internally on the longitudinal seam: the inner wall of the moving longitudinal seam can be welded by the cooperation of the welding machine body 2, the support plate 3, the gas supply system 4 and the welding gun 5; after the longitudinal seam inner wall welding is completed, the steel coil 30 completes the reciprocating movement on one side and returns to Figure 1 Position shown;

[0078] Position adjustment: Turn on the welding control motor 6. The welding control motor 6 drives the swivel 8 and the gear 2 34 to rotate through the gear 1 7. The swivel 8 drives the welding gun 5 to rotate 90 degrees through the L-shaped rod body 54, so that the position of the welding head is changed. The gear 2 34 drives the reciprocating screw rod 2 53 to rotate through the telescopic frame 35. The reciprocating screw rod 2 53 drives the bar rod 36 to move back and forth, but at this time only the bar rod 36 needs to move to the farthest position. In this process, the reciprocating screw rod 22 is driven to rotate through the cooperation of the bar rack 37 and the transmission gear 38. The reciprocating screw rod 22 rotates through the lifting block 23, the arc support plate 24, and the fixed roller 25 to drive the steel plate coil 30 and the welding rod 31 to move downward, so that the height of the steel plate coil 30 and the welding rod 31 can match the rotated welding head;

[0079] Perform external welding of the longitudinal seam on the steel plate coil 30 and the welding rod 31: Turn on the welding auxiliary motor 14, and the welding auxiliary motor 14 drives the reciprocating screw rod 15 to rotate through the one-way bearing 55, thereby driving the steel plate coil 30 and the welding rod 31 to perform a reciprocating motion. In this process, the external welding of the longitudinal seam can be completed by using the cooperation of the welding gun 5;

[0080] Removal after welding: control the welding auxiliary motor 14 to rotate in the opposite direction, and then drive the rotating drum 19 to rotate through the one-way bearing 256 and the transmission structure 1 20. The rotation of the rotating drum 19 drives the shaft body 17 to rotate through the bar clamping rod 21. The rotation of the shaft body 17 drives the shaft body 2 32 to rotate through the transmission structure 2 33. The rotation of the shaft body 2 32 drives the movable plate 57 to move. The movement of the movable plate 57 drives the adjusting gear 28 to rotate through the adjusting rack 29, thereby shortening the adjusting screw 26, so that the steel plate coil 30 loses the tightening and fixing effect provided by the tightening roller 27, which is convenient for removal. It should be noted here that in a complete process of the reciprocating movement of the movable plate 57, the steel plate coil 30 will first lose the tightening of the tightening roller 27, and the tightening effect will be re-applied to the steel plate coil 30. Therefore, in the removal process, it is only necessary to first move the movable plate 57 unidirectionally to the farthest position. When the newly placed steel plate coil 30 needs to be clamped later, the movable plate 57 is controlled to move and reset.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
