Description

Technical Field

[0001] This utility model relates to the field of container processing technology, and in particular to automatic welding of container sealing plates. Background Technology

[0002] The container sealing plate welding device is an industrial equipment specifically used for welding container door risers. In the container manufacturing process, the door riser is an important component of the container door. It needs to be firmly welded to the container door frame structure to provide sufficient strength and support. Before assembly, the two ends of the door riser need to be sealed to improve its quality.

[0003] The existing container sealing plate welding equipment uses a material handling machine to place the door risers. This material handling machine is purely manual, requiring employees to manually place the door risers onto the inclined slide. An automatic unloading machine then places the door risers one by one onto an automatic equidistant conveyor. The automatic equidistant conveyor arranges the door risers from the automatic unloading machine at equal intervals, preparing them for a reciprocating loading machine. The automatic reciprocating loading machine cycles through the three material states: "waiting to weld," "welding in progress," and "welding completed." The automatic clamping and positioning device positions and clamps the door risers in terms of height and horizontal direction. Then, sealing plates are welded to both ends of the door risers, and finally, the automatic unloading machine removes the door risers.

[0004] However, in implementing the relevant technology, the existing container sealing plate welding device has the following problems: the material placement machine of the existing device is manually placed, which can easily lead to the door uprights being placed crookedly. This may cause the automatic unloading machine to be unable to place the door uprights accurately, which in turn leads to errors in subsequent welding and easily reduces the processing quality of the door uprights. In view of this, an automatic container sealing plate welding device is provided to overcome the above defects. Utility Model Content

Two limiting frames are provided between the four connecting plates. Several rotating shafts are rotatably connected inside each of the two limiting frames. Rollers are fixed to the sides of each of the rotating shafts. Two sliders are fixed to the sides of each of the two threaded seats.

[0007] As a further description of the above technical solution: the inside of the adjustment frame has two sliding grooves, and the inside of the two sliding grooves are respectively slidably connected to the sides of the four sliders, so that the adjustment frame can protect the forward and reverse motors.

[0008] As a further description of the above technical solution: one end of the bidirectional threaded rod is rotatably connected to the inside of the adjusting frame, and one end of each of the support rods is fixedly connected to one side of the two fixed plates respectively. The bidirectional threaded rod facilitates the movement of the threaded seat.

[0009] As a further description of the above technical solution: the interior of the adjustment frame is provided with a number of movable holes, and the interior of the number of movable holes respectively fits into the side of a number of support rods, so that the support rods can easily fix the fixing plate.

[0010] As a further description of the above technical solution: the bottom ends of the two fixed seats are respectively fixedly connected to the top ends of several connecting rods, and one side of the four connecting plates is respectively fixedly connected to one side of the two limiting frames. The fixed seats facilitate the fixing of the connecting plates.

[0011] As a further description of the above technical solution: each of the two limiting frames has a limiting groove inside, and several rollers are respectively located inside the two limiting grooves, so that the rollers can limit the door vertical tube.

[0012] As a further description of the above technical solution: the bottom end of the base frame is provided with four fixing rods, the top ends of the four fixing rods are fixedly connected to the bottom end of the base frame, and the fixing rods facilitate the support of the base frame.

The support feet facilitate the improvement of the friction between the support rods and the ground.

[0014] This utility model has the following beneficial effects:

[0015] This utility model designs an automatic container sealing plate welding system. Through its design and coordination, several rollers limit the position of the door risers when they are placed on the placement frame of the unloading machine. This prevents the door risers from tilting during placement, minimizes friction between the rollers and the door risers, and does not affect the sliding of the door risers on the placement frame. The rotation of the forward and reverse motors can move the rollers closer together or further apart, making the spacing between the rollers easy to adjust. This allows the device to limit the position of door risers of different sizes, ensuring that the door risers are perpendicular to the placement frame. This facilitates accurate placement of the door risers by the automatic unloading machine, reduces errors during subsequent welding, and improves the processing quality of the door risers. Furthermore, the adjustable spacing of the rollers allows for the limiting of door risers of different sizes, thus expanding the applicability of the device. Attached Figure Description

[0023] As a further implementation of the above technical solution: the inside of the adjustment frame 2 is provided with two sliding grooves, and the inside of the two sliding grooves are respectively slidably connected to the sides of the four sliders 16. The adjustment frame 2 is convenient for protecting the forward and reverse motor 5.

[0024] As a further implementation of the above technical solution: one end of the bidirectional threaded rod 6 is rotatably connected to the inside of the adjusting frame 2, and one end of several support rods 8 is fixedly connected to one side of two fixed plates 9 respectively.

[0025] As a further implementation of the above technical solution: the interior of the adjustment frame 2 is provided with several movable holes, and the interior of the several movable holes respectively fits with the side of several support rods 8, so that the support rods 8 can fix the fixing plate 9.

[0026] As a further implementation of the above technical solution: the bottom ends of the two fixed seats 11 are respectively fixedly connected to the top ends of several connecting rods 10, and one side of the four connecting plates 12 is respectively fixedly connected to one side of the two limiting frames 13.

[0030] In practice: When welding the door riser tubes is required, the door riser tubes are first placed on the top of the placement frame 3. The cylinder 4 extends and retracts to rotate the placement frame 3, making the tilt angle of the placement frame 3 adjustable. This positions the door riser tubes near the critical point of sliding down. Multiple door riser tubes are then placed onto the placement frame 3 of the material handling machine. Subsequently, the automatic unloading machine places the door riser tubes from the material handling machine one by one onto the automatic equidistant conveyor. The automatic equidistant conveyor arranges the door riser tubes delivered by the automatic unloading machine at equal intervals, preparing them for the reciprocating feeding machine. The reciprocating feeding machine circulates the three materials—waiting to be welded, being welded, and welded—alternatingly. Automatic clamping and positioning are then used to achieve this. The positioning device positions and clamps the door riser tubes in both height and horizontal direction. Then, an automatic X-axis and Y-axis argon arc welding device positions and clamps the door riser tubes left and right, automatically feeding the sealing plate and performing automatic argon arc welding. An automatic unloading machine then removes the door riser tubes. When the door riser tubes are placed on the placement frame 3 of the unloading machine, several rollers 15 limit their movement, preventing them from tilting during placement. A rotating shaft 14 allows the rollers 15 to rotate within the limiting frame 13, minimizing friction between the rollers 15 and the door riser tubes and ensuring they slide smoothly on the placement frame 3. The rotation of the forward and reverse motor 5 drives the bidirectional threaded rod 6 to rotate, thus… The two threaded seats 7 are moved away from each other, which in turn moves the support rods 8 away from each other, which in turn moves the two fixed plates 9 away from each other, which in turn moves the connecting rods 10 away from each other, which in turn moves the two fixed seats 11 away from each other, which in turn moves the four connecting plates 12 away from each other, which in turn moves the two limit frames 13 away from each other, which in turn moves the rollers 15 away from each other. The reversing motor 5 reverses the direction of rotation, which in turn reverses the direction of rotation of the bidirectional threaded rod 6, which in turn moves the two threaded seats 7 closer together, which in turn moves the support rods 8 closer together, which in turn moves the two fixed plates 9 closer together, which in turn moves the connecting rods 10 closer together, which in turn moves the two fixed seats 11 closer together. The rollers move closer together, causing the four connecting plates 12 to move closer together, which in turn causes the two limiting frames 13 to move closer together, which in turn causes the rollers 15 to move closer together. This makes the spacing between the rollers 15 easy to adjust, allowing the device to limit the door vertical tubes of different sizes. This makes it easy for the device to limit the door vertical tubes by using the rollers 15, ensuring that the door vertical tubes are perpendicular to the placement frame 3. This facilitates the automatic unloading machine to accurately place the door vertical tubes, reducing errors during subsequent welding and improving the processing quality of the door vertical tubes. Furthermore, the adjustable spacing of the rollers 15 allows for the limiting of door vertical tubes of different sizes, thus expanding the applicability of the device.
