Description

Technical Field

[0001] This utility model relates to the field of receiving devices, and more particularly to a receiving trolley for a laser flat cutting machine. Background Technology

[0002] When a laser cutting machine cuts metal sheets, the high-temperature waste generated during the cutting process needs to be collected and transported away through a receiving device.

[0003] The commonly used material receiving device is usually a material receiving carriage, which consists of a carriage body and rollers mounted on the bottom of the carriage body. In the prior art, the bottom surface of the material receiving carriage is a single flat surface, and the rollers are usually directly mounted on the bottom surface of the carriage body to support the carriage body. Since the height of the material receiving carriage that can be inserted into the body of the laser cutting machine is limited, directly mounting the rollers on the bottom surface of the material receiving carriage will reduce the space of the material receiving cavity in the material receiving carriage; if a larger material receiving cavity space is required, the height of the laser cutting machine body needs to be increased accordingly, which will raise the center of gravity of the machine bed and cause instability in the machine bed structure. Utility Model Content

[0004] In order to improve the space utilization of the receiving trolley without increasing the height of the bed, this utility model provides a receiving trolley for a laser flat cutting machine.

[0005] The present invention provides a receiving trolley for a laser flat cutting machine, which adopts the following technical solution:

[0006] A receiving trolley for a laser planar cutting machine includes a trolley body and bottom rollers for the trolley body to roll and slide. The trolley body has a receiving cavity for receiving waste residue. A through hole is provided through the bottom surface of the receiving cavity, and a mounting cover is provided above the through hole to cover it. The mounting cover has a mounting cavity with an opening at the lower end. The bottom rollers pass through the through hole to the mounting cavity and are connected to the mounting cover.

[0007] The bottom roller has rotating teeth, and the trolley body is slidably provided with a meshing push rod that meshes with the rotating teeth and is used to drive the bottom roller to turn; the meshing push rod passes through the mounting cover.

[0008] By adopting the above technical solution, a through hole is opened at the bottom of the trolley body and covered by a mounting cover. The bottom roller is installed in an embedded manner. The bottom roller is installed into the mounting cavity through the through hole. Only a part of the bottom roller extends out of the bottom of the trolley body for rolling. This allows the trolley body to make full use of the space without changing the overall height, forming a large-volume receiving cavity for receiving materials, resulting in high material receiving efficiency.

[0009] Furthermore, the bottom roller's rotating teeth are driven to rotate by the telescopic movement of the meshing push rod, allowing the receiving trolley to turn when it exits the machine tool bed, instead of just moving along the set direction of the bottom roller. This makes it easier for the receiving trolley to unload materials, which is more convenient.

[0010] Optionally, the bottom roller is connected to the mounting cover via a mounting structure, the mounting structure including a connecting plate disposed in the mounting cavity and a welding nut pre-fixed to the connecting plate for mounting the bottom roller.

[0011] By adopting the above technical solution, the connecting plate and welding nut are pre-fixed in the installation cavity. When the bottom roller is installed in the installation cavity, the top of the bottom roller is directly fixed to the welding nut, making disassembly and assembly relatively simple.

[0012] Optionally, the top of the connecting plate is provided with an arrangement groove, and the welding nut passes through the arrangement groove. When the connecting plate is fixed to the top of the mounting cavity, the connecting plate presses the welding nut tightly against the top of the mounting cavity.

[0013] By adopting the above technical solution, when the connecting plate and welding nut are pre-fixed in the installation cavity, the connecting plate can press the welding nut tightly in the installation cavity, making the welding nut less prone to loosening and improving structural stability.

[0014] Optionally, the engagement push rods are symmetrically arranged on the trolley body, and the trolley body is provided with a connecting rod connecting the two engagement push rods and a drive assembly disposed on the connecting rod and driving the engagement push rods to slide.

[0015] By adopting the above technical solution, the meshing push rods on both sides are connected by the connecting rod and driven simultaneously by the drive assembly, so that the meshing push rods on both sides can drive all the bottom rollers, making it easier to control the direction of the receiving trolley.

[0016] Optionally, the drive assembly includes a rotating disk and a drive hand that drives the rotating disk to rotate. The rotating disk has a drive rod, and the connecting rod has a sliding groove for the drive rod to slide to drive the engagement push rod to slide.

[0017] By adopting the above technical solution, the drive assembly can convert the linear motion of the meshing push rod into the rotation of the drive hand, which is convenient for the operator to operate and saves effort.

[0018] Optionally, the vehicle body includes multiple detachable main body units, and adjacent main body units are connected by a connecting structure to increase the length of the vehicle body.

[0019] By adopting the above technical solution, the main body of the trolley adopts a split design, which makes the main body of the trolley more flexible and able to adapt to the processing needs of different laser cutting machines, while also facilitating the maintenance and upkeep of the trolley.

[0020] Optionally, the connection structure includes connecting bolts installed at intervals for connecting adjacent main units and a welding stiffener plate connected to the inner wall of the receiving cavity for the connecting bolts to pass through simultaneously.

[0021] By adopting the above technical solution, multiple main units are connected by connecting bolts, making disassembly and assembly relatively simple; by setting welding stiffeners, the wall thickness of the main unit can be increased, and the clamping force of the connecting bolts can be evenly distributed through the welding stiffeners, thereby improving the connection stability of the main unit.

[0022] Optionally, the main body unit has symmetrically provided lifting holes on both sides, which penetrate inside and outside and are used for lifting and dumping waste residue when the trolley body is withdrawn from the machine tool bed.

[0023] By adopting the above technical solution, when the receiving trolley exits from the machine tool bed, the lifting device connected to the lifting hole can lift the receiving trolley and dump the waste inside, thereby facilitating the transportation and material removal of the receiving trolley; and because the receiving trolley is protected by the lifting device through the lifting hole during transportation, the transportation process is safer.

[0024] Optionally, the receiving cavity is provided with a lifting hole reinforcing plate at the lifting hole to thicken the wall at the lifting hole.

[0025] By adopting the above technical solution, the lifting hole reinforcement plate can increase the wall thickness at the lifting hole, improve the overall structural strength, and make the material receiving trolley less prone to cracking at the lifting hole during the lifting process due to the large amount of waste residue inside.

[0026] Optionally, the bottom surface of the trolley body is covered with refractory bricks to prevent the inner wall of the trolley body from being eroded by high-temperature waste residue.

[0027] By adopting the above technical solution and laying refractory bricks, the inner wall of the receiving trolley does not need to be in direct contact with high-temperature waste residue, thereby avoiding corrosion of the trolley body, extending the service life of the receiving trolley, and making the structure of the receiving trolley more robust and durable.

[0028] In summary, this utility model has at least one of the following beneficial technical effects:

[0029] 1. The bottom rollers are installed using an embedded installation method, with only a portion of the bottom rollers extending from the bottom of the trolley body for rolling. This allows the trolley body to make full use of the space without changing its overall height, forming a large-volume receiving cavity for receiving materials, resulting in high material receiving efficiency.

[0030] 2. When the bottom roller is located inside the mounting cavity, the mounting cover can protect the bottom roller, preventing the laser from corroding the wheel, thereby improving the lifespan of the bottom roller;

[0031] 3. The main body of the trolley adopts a split design, which makes the trolley more flexible and adaptable to the processing needs of different laser cutting machines, while also facilitating the maintenance and upkeep of the trolley. Attached Figure Description

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0039] This utility model discloses a receiving trolley for a laser planar cutting machine.

[0040] Reference Figure 1 and Figure 2 A receiving trolley for a laser planar cutting machine includes a trolley body 1 and bottom rollers 2. The trolley body 1 has a receiving cavity 3 for receiving waste slag generated from cutting steel by the laser cutting machine. The bottom rollers 2 are used to support the trolley body 1 and for the trolley body 1 to roll horizontally. In use, the receiving trolley body 1 is inserted into the machine tool bed, the receiving cavity 3 can receive the waste slag, and finally the bottom rollers 2 remove the trolley body 1 from the machine tool bed.

[0041] Reference Figure 2 The trolley body 1 can be a single piece or a split piece. In this embodiment, the trolley body 1 is a detachable split piece structure, which includes multiple main body units 11 connected by a connecting structure 4. The lengths of the main body units 11 can be equal or unequal. By connecting multiple main body units 11, a trolley body 1 suitable for the operating conditions of the laser cutting machine currently in use is formed.

[0042] In this embodiment, the connecting structure 4 includes connecting bolts 41 and reinforcing ribs 42. The reinforcing ribs 42 are rectangular plates, welded to the inner wall of the main body unit 11 and located at both ends of the main body unit 11 along its length. The reinforcing ribs 42 are used to thicken the wall of the main body unit 11 at the connection point, thus improving the structural strength of the main body unit 11. The connecting bolts 41 pass through the reinforcing ribs 42 and the main body unit 11 to fix two adjacent main body units 11 together. Multiple connecting bolts 41 are arranged along the length of the reinforcing ribs 42 to improve the connection stability of adjacent main body units 11.

[0043] Reference Figure 2 and Figure 3 To adapt to the machine tool bed and fully utilize the space of the receiving cavity 3 of the receiving trolley, the bottom rollers 2 are installed on the main body unit 11 in an embedded manner. The main body unit 11 has through holes 12 circumferentially formed on the inner bottom surface of the receiving cavity 3, penetrating both the inner and outer surfaces of the main body unit 11. In this embodiment, there are six through holes 12, symmetrically distributed in the receiving cavity 3. Furthermore, the main body unit 11 is also fitted with a mounting cover 51 inside the receiving cavity 3 by welding, which covers the through holes 12. The mounting cover 51 is a square box shape with a mounting cavity 54 open at the lower end, allowing communication between the through holes 12 and the mounting cavity 54.

[0044] The bottom roller 2 passes through the through hole 12 via the mounting structure 5 and is installed in the mounting cavity 54, such that only a portion of the bottom roller 2 protrudes from the bottom of the main body unit 11. The mounting structure 5 includes a connecting plate 52 and a welding nut 53. The connecting plate 52 has a U-shaped cross-section and an arrangement groove 55 at its upper end. The welding nut 53 is disposed in the arrangement groove 55 and vertically passes through the connecting plate 52, such that the thread of the welding nut 53 extends downward beyond the connecting plate 52. The welding nut 53 can be threaded onto the connecting plate 52 or directly welded to the connecting plate 52; in this embodiment, welding is preferred. In this embodiment, the connecting plate 52 is welded to the inner bottom surface of the mounting cavity 54 with the arrangement groove 55 facing upward, to further press the welding nut 53 against the inner bottom surface of the mounting cavity 54.

[0045] When installing the bottom roller 2, the bottom roller 2 is inserted into the mounting cavity 54 through the through hole 12 at the bottom of the main body unit 11, and the bottom roller 2 is connected and fixed with the welding nut 53. When the bottom roller 2 is in the mounting cavity 54, the mounting cover 51 can also protect the bottom roller 2, making the bottom roller 2 less susceptible to damage from laser and high temperature.

[0046] Reference Figure 2 Furthermore, when the receiving trolley retracts from the machine tool bed, in order to facilitate the dumping of waste residue by the receiving trolley, symmetrical lifting holes 6 are provided on both sides of the main body unit 11 for lifting and dumping waste residue. The lifting holes 6 penetrate the inner and outer surfaces of the main body unit 11. In order to strengthen the structural strength of the main body unit 11 at the lifting holes 6, a lifting hole reinforcing plate 7 is provided on the inner wall of the main body unit 11 at the lifting holes 6 by welding.

[0047] Furthermore, the main unit 11 has refractory bricks 8 laid on the inner bottom surface of the receiving chamber 3. The refractory bricks 8 have high temperature resistance, which can prevent the receiving chamber 3 from being corroded by high temperature waste residue and laser when the receiving trolley is located in the machine tool bed to receive materials.

[0048] Furthermore, the side wall of the trolley body 1 is connected to a handle 9 to facilitate the removal of the receiving trolley from the machine tool bed after receiving the material.

[0049] Reference Figure 3 and Figure 4 Furthermore, in order to enable the receiving trolley to turn, the bottom roller 2 has rotating teeth 21, and a meshing push rod 56 is slidably disposed on the trolley body 11. The meshing push rod 56 passes horizontally through the trolley body 1 and the mounting cover 51 and meshes with the rotating teeth 21. The meshing push rods 56 are symmetrically arranged on the trolley body 1 so that they can mesh with the rotating teeth 21 of the bottom rollers 2 on both sides.

[0050] Reference Figure 4 and Figure 5Two meshing push rods 56 are connected by a connecting rod 57 and driven by a drive assembly 58 so that the two meshing push rods 56 can slide synchronously. The drive assembly 58 includes a mounting plate 581 welded to the handle 9, a rotating disk 582 rotatably mounted on the mounting plate 581, and a drive hand 583 that drives the rotating disk 582 to rotate. The bottom of the rotating disk 582 has a drive rod 584, and the top of the connecting rod 57 is provided with a sliding groove 571 for the drive rod 584 to slide.

[0051] Combination Figure 2 , Figure 4 and Figure 5 When the drive hand 583 drives the rotating disk 582 to rotate, the drive rod 584 can slide in the sliding groove 571 of the connecting rod 57, thereby driving the connecting rod 57 to move along the length direction of the meshing push rod 56. Since the meshing push rod 56 is connected to the connecting rod 57, the meshing push rod 56 can slide synchronously with the connecting rod 57, and the bottom roller 2 can turn.

[0052] In order to make the engagement push rod 56 adaptable to the split structure of the trolley body 1, the engagement push rod 56 is formed by connecting multiple units, and adjacent engagement push rods 56 are locked to each other by locking hooks 561.

All technical solutions falling within the scope of this utility model's concept are within its protection scope. For those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
