Description

Technical Field

[0001] The utility model relates to the technical field of powder coating processing, in particular to a powder coating unloading system. Background Art

[0002] During the powder coating processing, various single-color powders are first poured into the material tank according to a certain proportion, and then the various powders in the material tank are stirred and mixed through the stirring mechanism. The mixed powders are then transferred to the hot melt machine through the material tank for hot melting.

[0003] At present, when feeding powder into the hot melt machine through the material cylinder, since the feed port of the hot melt machine is set at the top, the advantage of this design is that when the powder is added into the feed port, the powder can fall into the hot melt machine by its own gravity, which can avoid the powder from being retained on the inner wall of the feed pipe. Therefore, the existing feeding method is to first lift the material cylinder with a gantry truck, transport the material cylinder to the feed pipe at the top of the hot melt machine, and then connect the discharge pipe of the material cylinder with the feed pipe to complete the unloading;

[0004] However, an obvious problem arises in this process: since the gantry crane is lifted by a flexible sling, it is very unstable when achieving the docking and unloading of the feed pipe and the discharge pipe. The swing amplitude is large and the docking process takes a long time. In addition, the gantry crane is used to lift the cylinder to a high place for unloading. Since the feed pipe does not bear weight, the gantry crane needs to lift the cylinder for a long time, which poses a great safety hazard to the staff below.

[0005] Therefore, there is an urgent need for a powder coating unloading system to assist in unloading the material cylinder, improve unloading efficiency, and reduce safety hazards. Utility Model Content

[0006] In response to the above technical problems, the utility model provides a powder coating unloading system, which is used to solve the problem that when the material cylinder is currently unloaded through a gantry truck, the efficiency of the docking process between the feed pipe of the hot melt machine and the discharge pipe of the material cylinder is low because the gantry truck is lifted by a flexible sling. In addition, there is a very serious safety hazard when using the gantry truck to lift the material cylinder and lift it to a high place for unloading.

[0007] The above technical objectives of the present invention are achieved through the following technical solutions:

[0008] A powder coating unloading system includes a main body, a transfer vehicle, and a material cylinder. The transfer vehicle includes a ground rail and a frame disposed on the ground rail. The frame is equipped with wheels and a drive motor. The frame is provided with a docking unit. The docking unit includes four elastic lifting devices and a docking frame. The docking frame can be raised and lowered under the action of the four elastic lifting devices. The docking frame includes a bottom plate, a docking port is provided in the center of the bottom plate, and limit guide frames are symmetrically provided on the bottom plate.

[0009] A support frame is mounted on the material cylinder, and the support frame is located between two limiting guide frames. A universal wheel is provided at the bottom of the support frame, and a discharge pipe is provided at the bottom center of the material cylinder. The limiting guide frame is used to achieve concentricity between the discharge pipe and the docking port.

[0010] Furthermore, the limiting guide frame includes a cross beam, both ends of which are respectively connected to the elastic jacking device, a connecting beam is provided on the side of the cross beam close to the base plate, the connecting beam is connected to the base plate, the cross beam is provided with a guide rod along the direction of movement of the cylinder, and a limiting rod is provided at one end of the guide rod perpendicular to the axial direction.

[0011] Furthermore, a brake plate is provided on the guide rod, a sleeve is provided on the brake plate, and a latch is provided in the sleeve.

[0012] Furthermore, there are two vehicle frames, and an aisle is provided on one of the vehicle frames.

[0013] Furthermore, the support frame is in a U-shaped structure, and a plurality of support columns are provided on the support frame, and handles are provided on the support columns.

[0014] Furthermore, a limiting plate is provided on the support frame.

[0015] Furthermore, a guide piece is provided at the other end of the guide rod.

[0016] In summary, the beneficial technical effects of the present invention are:

[0017] Four elastic jacking devices are used to lift the entire docking frame upward until the bottom plate is flush with the elevator, and then the material cylinder is moved to the bottom plate through the universal wheel through the support frame, and the discharge pipe of the material cylinder is placed in a position concentric with the docking port through the limit guide frame, and then the material cylinder is dropped through the elastic jacking device to finally complete the docking and unloading of the discharge pipe and the feed pipe in the docking port. In this process, the bottom plate supports the entire material cylinder, and there is no need for lifting by a gantry truck, which improves the stability and work efficiency during docking and also reduces the safety risks during unloading.

[0025] The present invention will be described clearly and completely below with reference to the embodiments.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] In the description of the embodiments, unless otherwise specified or limited, the terms "disposed" and "connected" should be understood broadly. For example, they can refer to fixed, removable, or integral connections; mechanical or electrical connections; direct connections, connections through an intermediary medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on their specific circumstances.

[0028] See attached Figure 1-6 , shown is a powder coating unloading system, including a transfer vehicle and a material tank 6, wherein the transfer vehicle includes two parallel ground rails 3, each of which is provided with a frame 1, and wheels 2 that cooperate with the ground rails 3 are mounted at both ends of the frame 1, one of the wheels 2 is further provided with a drive motor 4, which drives the frame 1 to move on the ground rails 3;

[0029] A docking unit is provided between the two vehicle frames 1, wherein the docking unit comprises four elastic lifting devices 5 and a docking frame. Each vehicle frame 1 is provided with two elastic lifting devices 5, and the elastic lifting devices 5 are specifically an air bag. The docking frame is installed on the top of the elastic lifting devices 5. The entire docking frame is raised and lowered by inflating the elastic lifting devices 5.

[0030] The docking frame includes a bottom plate 9, a docking port 10 is provided in the center of the bottom plate 9, and the feed pipe 23 on the hot melt machine extends from the docking port 10 during unloading to dock with the material cylinder 6. A limit guide frame is symmetrically provided on both sides of the bottom plate 9, wherein the limit guide frame includes two parallel beams 11, and both ends of each beam 11 are bolted to the corresponding elastic jacking device 5. A connecting beam 12 is provided on the side of the beam 11 close to the bottom plate 9, and the connecting beam 12 is connected to the bottom plate 9. When in use, the elastic jacking device 5 pushes the two beams 11 upward, and the two beams 11 further drive the bottom plate 9 to rise upward through the connecting beam 12;

[0031] Furthermore, a guide rod 13 is provided on the side where the two cross beams 11 are close to each other. One end of the guide rod 13 is provided with a guide member 14 inclined outward, and the other end is provided with a limit rod 15 perpendicular to the axial direction. At the same time, a brake plate 16 is provided in the middle of the guide rod 13. A sleeve is provided on the brake plate 16 perpendicular to the axial direction of the guide rod 13, and a pin 17 is provided in the sleeve.

[0032] It can be seen that by connecting the docking frame and the elastic jacking device 5, the two frames 1 and the docking frame are connected as a whole, so that the frame 1 and the docking frame can be driven by the drive motor 4 to move along the ground rail 3;

[0033] Furthermore, a U-shaped support frame 7 is mounted on the cylinder 6. The width of the support frame 7 can be accommodated between the two guide rods 13. At the same time, the height of the support frame 7 is consistent with the height of the limit rod 15. A universal wheel 8 is provided at the bottom of the support frame 7. In addition, a limit plate 21 is provided at the position of the latch 17 of the support frame 7.

[0034] At the same time, a plurality of support columns 19 are vertically fixed on the support frame 7, and the material cylinder 6 is erected therein through the support columns 19. The bottom of the material cylinder 6 is conical, and a discharge pipe 22 is provided at the center of the bottom. The discharge pipe 22 is equipped with a control valve 24. When in use, the material cylinder 6 is lifted by the elevator, and then the elastic jacking device 5 is used to lift the entire docking frame to a position where the bottom plate 9 is flush with the elevator. After that, the material cylinder 6 is transferred to the bottom plate 9 through the universal wheel 8, and then the limit rod 15 and the latch 17 are used to realize the front and rear limit fixation of the entire support frame 7. At this time, the discharge pipe 22 of the material cylinder 6 is exactly in a concentric position with the docking port 10, and then the material cylinder 6 is dropped by the elastic jacking device 5 and accurately docked with the feed pipe 23 on the hot melt machine. In this process, the docking unit is used to replace the original gantry crane for lifting and docking, which not only improves the stability during docking, but also utilizes the front and rear limit of the support frame 7 to achieve accurate docking of the discharge pipe 22 and the feed pipe 23, thereby improving the work efficiency during docking. Most importantly, by replacing the gantry crane, the safety hazards during unloading are greatly reduced.

[0035] When unloading, the elevator first lifts the mixed powder cylinder 6 to a position close to the bottom plate 9, and then the elastic jacking device 5 is pressurized to lift the entire docking frame upward to a position where the bottom plate 9 is flush with the elevator, and then the handle 20 on the support column 19 is used to transfer the cylinder 6 along the guide member 14 to the bottom plate 9, and one end of the support frame 7 is abutted against one side of the limit rod 15, and then the pin 17 is pushed out and blocked on the rear side of the limit plate 21, so that the front and rear limit of the support frame 7 is achieved, and the purpose of concentricity of the discharge pipe 22 of the cylinder 6 and the docking port 10 is achieved, and then the feed pipe 23 on the hot melt machine is extended from the docking port 10, and then the elastic jacking device 5 is used to drop the cylinder 6 until the discharge pipe 22 and the feed pipe 23 are docked, and then it reaches the bottom plate 9 through the aisle 18 on the frame 1, and the control on the discharge pipe 22 is opened for unloading.

[0036] Another beneficial effect of the present invention is that after the material cylinder 6 is transferred to the bottom plate 9, the feed tube 23 is retracted. At this time, the material cylinder 6 can be driven by the driving motor 4 to move along the ground rail 3 to achieve the purpose of unloading for multiple hot melt machines.

[0037] It should be noted that a cylinder is provided on the top of the hot melt machine for controlling the lifting and lowering of the feed pipe 23. This structure is a prior art and will not be described in detail.

[0038] It should be noted that, after the bottom plate 9 is lifted up by the elastic lifting device 5 , the bottom plate 9 is at the same height as the corresponding vehicle frame 1 and the elevator, thus avoiding interference of the vehicle frame 1 with the universal wheel 8 .

[0039] The above description is only a preferred specific embodiment of the present invention and does not limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
