Description

Technical Field

[0001] This application relates to the field of surface treatment apparatus, and in particular to a surface treatment apparatus for a forklift balance block and its treatment process. Background Technology

[0002] A forklift counterweight is a type of weight installed at the rear of a forklift to balance the vehicle.

[0003] The counterweight is cast in one piece. After casting, the surface of the counterweight usually needs to be polished and deburred. To improve the cleaning effect, a surface treatment device is typically used. This device mainly includes a sandblasting box and several shot blasting machines. The shot blasting machines are evenly arranged on the sandblasting box, which has movable holes. A movable frame is fixed to the sandblasting box, and a movable seat is slidably connected to the movable frame. The movable seat has hooks for lifting the counterweight. The movable seat moves the hooks with the counterweights along the movable holes to move the counterweights into the sandblasting box. At this time, the shot blasting machines start and can treat the surface of the counterweights.

[0004] In actual use, the metal particles thrown out by the shot blasting machine collide with the counterweight and are ejected. Some metal particles are easily discharged from the sandblasting box through the moving hole, reducing the residence time of the metal particles in the sandblasting box. At this time, it is necessary to replenish the metal particles to meet the polishing requirements of the counterweight, which affects the efficiency of the surface treatment device in processing the counterweight. Therefore, it needs to be improved. Summary of the Invention

[0005] To address the aforementioned issues, this application provides a forklift balance block surface treatment device and its processing technology.

[0006] This application provides a surface treatment device for forklift balance weights, which adopts the following technical solution:

[0007] A surface treatment device for a forklift counterweight includes a sandblasting box, a sandblasting assembly, and a conveying assembly for conveying the counterweight. Both the sandblasting assembly and the conveying assembly are mounted on the sandblasting box. The sandblasting box has a movable hole, and several sets of first and second baffles are provided within the movable hole. Each set of first and second baffles is arranged opposite to each other. The sandblasting box also has several sets of support assemblies, with each first and second baffle corresponding to a set of support assemblies. The sandblasting box has a sealing assembly for blocking the movable hole. The sealing assembly is connected to the support assemblies via a control assembly. When the sealing assembly closes the movable hole, the control assembly drives the support assemblies to support the first or second baffle at the corresponding position.

[0008] By adopting the above technical solution, workers use a conveying assembly to move the counterweight into the sandblasting box. When the counterweight reaches the set position, the sealing assembly activates and blocks the moving hole. During the operation of the sealing assembly, it drives the control assembly, which in turn activates the support assembly. The support assembly then supports the first or second baffle at the corresponding position, ensuring that the first and second baffles stably block the moving hole. Simultaneously, in conjunction with the sealing assembly, this prevents metal particles ejected by the sandblasting assembly from easily exiting through the moving hole. This allows the sandblasting assembly to process the counterweight more stably, thereby improving the processing efficiency of the counterweight.

[0009] Preferably, the enclosed assembly includes a control seat, a first baffle, and a second baffle. The sandblasting box has a control slot, and the control seat is disposed in the control slot. A first connecting rod and a second connecting rod are rotatably connected to the control seat. The end of the first connecting rod away from the control seat is rotatably connected to the first baffle, and the end of the second connecting rod away from the control seat is rotatably connected to the second baffle. Both the first baffle and the second baffle are slidably connected to the sandblasting box. The control seat is provided with a synchronizing element for controlling the synchronous rotation of the first connecting rod and the second connecting rod.

[0010] By adopting the above technical solution, when the counterweight moves to the set position, the synchronizing component is activated and synchronously drives the first connecting rod and the second connecting rod to rotate synchronously. The first connecting rod then drives the first baffle to move, and the second connecting rod then drives the second baffle to move, thus realizing the function of synchronously controlling the movement of the first and second baffles. After the first and second baffles abut against each other, the moving hole can be blocked.

[0011] Preferably, the synchronizing element includes a first motor, a first gear, and a second gear. The first motor is mounted on a control base, the first gear is coaxially mounted on the output end of the first motor, and the second gear is rotatably connected to the control base. The second gear meshes with the first gear. Both the first connecting rod and the second connecting rod have driven gears on their rotating shafts. The driven gear corresponding to the first connecting rod meshes with the first gear, and the driven gear corresponding to the second connecting rod meshes with the second gear.

[0012] By adopting the above technical solution, after the counterweight moves to the set position, the first motor starts and drives the first gear to rotate. One side of the first gear drives the driven gear on the first baffle to rotate, and the other side sequentially drives the second gear and the driven gear on the second baffle to rotate, so that the first baffle and the second baffle rotate in opposite directions, that is, control the first baffle and the second baffle to rotate in opposite directions. After the first baffle and the second baffle come into contact, the moving hole can be blocked.

[0013] Preferably, the support assembly includes a support plate and a driving component. The first and second baffles are each provided with a support groove. The sandblasting box is provided with a driving cavity. The inner wall of the driving cavity is provided with a driving hole that communicates with the support groove. The support plate is slidably connected in the driving hole. One end of the driving component is connected to the support plate and the other end is connected to the second gear.

[0014] By adopting the above technical solution, the second gear rotates, driving the drive component to start. The drive component then moves the support plate along the drive hole, causing the support plate to insert into the support groove at the corresponding position. At this time, the support plate can support the first baffle or the second baffle at the corresponding position, improving the internal structural strength of the first and second baffles, thereby improving the ability of the first and second baffles to block metal particles ejected by the sandblasting assembly.

[0015] Preferably, the driving component includes a driving shaft and a plurality of driving gears. The driving shaft is rotatably connected in the driving cavity. Each of the driving gears is coaxially arranged on the driving shaft. Each of the driving gears corresponds to a support plate. The driving gear meshes with the support plate at the corresponding position. One end of the control component is connected to the second gear and the other end is connected to the driving shaft.

[0016] By adopting the above technical solution, the second gear rotates and, under the transmission action of the control component, drives the drive shaft to rotate. The drive shaft then drives each drive wheel to rotate, and each drive wheel drives the corresponding support plate to move along the support hole, so that the support plate is inserted into the corresponding first or second baffle. The support plate can then support the corresponding first or second baffle.

[0017] Preferably, the conveying assembly includes a conveying frame and a guide rail. The conveying frame is mounted on the sandblasting box, and the guide rail is mounted on the side of the conveying frame near the sandblasting box. A movable seat is slidably connected to the guide rail, and a hook is provided on the side of the movable seat near the sandblasting box.

[0018] By adopting the above technical solution, the worker uses a strip to hang the counterweight on the hook, and then controls the moving seat to move along the guide rail. The moving seat can then move the counterweight into the sandblasting box so that the sandblasting component can process the counterweight.

[0019] Preferably, the sandblasting box is connected to a balance pipe, and the balance pipe is provided with a blocking component. The blocking component includes a cover plate and several sealing plates. The cover plate is slidably connected in the balance pipe, and the several sealing plates are rotatably connected in the balance pipe. The balance pipe is provided with a synchronization component for synchronously controlling the synchronous movement of the cover plate and each sealing plate.

[0020] By adopting the above technical solution, when processing the counterweight, the synchronization component starts and moves the cover plate away from the balance pipe, while simultaneously rotating each sealing plate, connecting the balance pipe to the outside world and the sandblasting box. During the sandblasting process, the balance pipe ensures that the sandblasting box and the outside world maintain the same pressure, minimizing pressure differences. At the same time, the sealing plates block metal particles ejected by the sandblasting component, reducing the likelihood of metal particles exiting the sandblasting box through the balance pipe.

[0021] Preferably, the synchronization component includes a synchronization rod and several synchronization blocks. A clearance cavity is provided in the balance tube. The synchronization rod is slidably connected in the clearance cavity. Each synchronization block is disposed on the synchronization rod. Each synchronization block corresponds to a sealing plate. Each sealing plate extends into the clearance cavity. Each sealing plate is connected to the synchronization block at the corresponding position through a connector. A movable rod is provided on the cover plate. The movable rod extends into the clearance cavity. The movable rod is slidably connected to the inner wall of the clearance cavity. The synchronization rod is connected to the movable rod.

[0022] By adopting the above technical solution, the synchronizing rod moves and drives the various synchronizing blocks to move. Under the transmission action of the connecting parts, the synchronizing blocks can drive the corresponding sealing plates to rotate, thereby adjusting the angle of the sealing plates. At the same time, the synchronizing rod then drives the moving rod and the synchronizing rod to move, and the moving rod then drives the cover plate to move, so that the balance pipe is connected to the outside world and the sandblasting box.

[0023] Preferably, the connector includes a dovetail block, and each of the synchronization blocks is provided with a dovetail block. The sealing plate has a dovetail groove at one end of the relief cavity, and the dovetail block is slidably connected in the dovetail groove.

[0024] By adopting the above technical solution, the synchronizing rod drives each synchronizing block to move, and the synchronizing block drives the corresponding dovetail block to move. Under the guidance of the dovetail groove, the dovetail block can drive the corresponding sealing plate to rotate. When it is necessary to reset the sealing plate, the synchronizing rod moves in the opposite direction. At this time, under the action of the dovetail block, the sealing plate can be controlled to reset, thus providing convenience for controlling the movement of the sealing plate.

[0025] This application also discloses a processing technology for a forklift counterweight surface treatment device, including the following steps:

[0026] The conveying assembly conveys the counterweight to the sandblasting box, and the sealing assembly seals the moving hole;

[0027] The closed component drive control component controls the support component to support the first baffle or the second baffle at the corresponding position;

[0028] The sandblasting assembly performs sandblasting on the counterweight.

[0029] By adopting the above technical solution, when the sandblasting component processes the counterweight, the support component supports the first baffle or the second baffle at the corresponding position. At this time, the sealing component cooperates with the first baffle and the second baffle to provide double obstruction for the moving hole, making it difficult for the metal particles sprayed by the sandblasting component to be discharged from the moving hole, so that the sandblasting component can process the counterweight more stably, thereby improving the efficiency of the processing device in processing the counterweight.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. By setting up a sealing component, a first baffle, and a second baffle, a double obstruction is provided for the moving hole, making it difficult for the metal particles ejected by the sandblasting component to be discharged from the moving hole, so that the sandblasting component can process the counterweight more stably, thereby improving the efficiency of the processing device in processing the counterweight.

[0032] 2. By setting a support component, the support component supports the first baffle or the second baffle at the corresponding position, so that the first baffle and the second baffle can stably block the moving hole, thereby improving the structural strength of the first baffle and the second baffle and making it difficult for the metal particles of the sandblasting component to be discharged from the moving hole;

[0033] 3. By setting up a balance pipe, the pressure between the sandblasting box and the outside environment can be easily balanced, so that the sandblasting assembly can process the counterweight more stably. Attached Figure Description

Detailed Implementation

[0041] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0042] This application discloses a surface treatment device for forklift balance weights. (Refer to...) Figure 1 and Figure 2 A surface treatment device for a forklift counterweight includes a sandblasting box 1, a sandblasting assembly 11, and a conveying assembly 2 for conveying the counterweight. Both the sandblasting assembly 11 and the conveying assembly 2 are mounted on the sandblasting box 1. The sandblasting box 1 has a movable hole 12, in which several sets of first baffles 121 and second baffles 122 are arranged, each set of first baffles 121 and second baffles 122 being arranged opposite to each other. The sandblasting box 1 has several sets of support assemblies 3, with each first baffle 121 and second baffle 122 corresponding to a set of support assemblies 3. The sandblasting box 1 has a sealing assembly 4 for blocking the movable hole 12, and the sealing assembly 4 is connected to the support assemblies 3 via a control assembly 5. When the sealing assembly 4 blocks the movable hole 12, the control assembly 5 drives the support assemblies 3 to support the corresponding first baffle 121 or the corresponding second baffle 122.

[0043] The conveying component 2 moves the counterweight to the designated position. The sealing component 4 then activates and seals the moving hole 12. Simultaneously, the sealing component 4 activates the control component 5, which in turn drives the support component 3. The support component 3 then supports the corresponding first baffle 121 or the corresponding second baffle 122, improving the structural strength of the first and second baffles 121 and 122. The sandblasting component 11 then activates and processes the counterweight. At this time, each of the first and second baffles 121 cooperates with the sealing component 4 to seal the moving hole 12, making it difficult for metal particles ejected by the sandblasting component 11 to escape from the moving hole 12. This allows the sandblasting component 11 to process the counterweight more stably, thereby improving the efficiency of the processing device in processing the counterweight.

[0044] Reference Figure 2 and Figure 3 The sandblasting assembly 11 includes several shot blasting machines 111, and each shot blasting machine 111 is evenly arranged on the sandblasting box 1.

[0045] The conveying assembly 2 includes a conveying frame 21 and a guide rail 22. The conveying frame 21 is mounted on the sandblasting box 1, and the guide rail 22 is fixed to the side of the conveying frame 21 near the sandblasting box 1. A movable seat 23 is slidably connected to the guide rail 22, and a hook 24 is fixed to the side of the movable seat 23 near the sandblasting box 1. A drive motor 25 is fixed to the movable seat 23, and an adjusting gear 26 is coaxially fixed to the output end of the drive motor 25. A rack 27 is fixed to the guide rail 22 along its length, and the adjusting gear 26 meshes with the rack 27. A pulley 28 is rotatably connected to the movable seat 23, and the pulley 28 abuts against the guide rail 22.

[0046] Workers use a chain to hoist the counterweight onto the hook 24, then start the drive motor 25. The drive motor 25 drives the adjusting gear 26 to rotate. Guided by the rack 27 and the guide rail 22, the movable seat 23 moves along the guide rail 22. The movable seat 23 then moves the hook 24, which is equipped with the counterweight, into the sandblasting box 1. During the movement of the movable seat 23, the pulley 28 changes the sliding friction between the guide rail 22 and the movable seat 23 into rolling friction, reducing the frictional force between the movable seat 23 and the guide rail 22, thereby improving the stability of the movable seat 23 during movement.

[0047] Reference Figure 2 and Figure 4 The enclosed assembly 4 includes a control seat 41, a first baffle 42, and a second baffle 43. A control groove 13 is provided on the sandblasting box 1. The control seat 41 is fixed in the control groove 13. A first connecting rod 44 and a second connecting rod 45 are rotatably connected to the control seat 41. The end of the first connecting rod 44 away from the control seat 41 is rotatably connected to the first baffle 42, and the end of the second connecting rod 45 away from the control seat 41 is rotatably connected to the second baffle 43.

[0048] The first baffle 42 and the second baffle 43 are both slidably connected to the sandblasting box 1. A first auxiliary rod 14 and a second auxiliary rod 15 are rotatably connected to the sandblasting box 1. The first auxiliary rod 14 and the second auxiliary rod 15 are arranged opposite to each other, and the end of the first auxiliary rod 14 away from the sandblasting box 1 is rotatably connected to the first baffle 42, and the end of the second auxiliary rod 15 away from the sandblasting box 1 is rotatably connected to the second baffle 43. The first auxiliary rod 14 is parallel to the first connecting rod 44, and the second auxiliary rod 15 is parallel to the second connecting rod 45. A synchronizing element 46 is provided on the control base 41 for controlling the synchronous rotation of the first connecting rod 44 and the second connecting rod 45.

[0049] Reference Figure 2 and Figure 4 Synchronizing element 46 includes a first motor 461, a first gear 462, and a second gear 463. The first motor 461 is fixed on the control base 41. The first gear 462 is coaxially fixed on the output end of the first motor 461. The second gear 463 is rotatably connected to the control base 41 and meshes with the first gear 462. Driven gears 464 are coaxially fixed on the rotating shafts of the first connecting rod 44 and the second connecting rod 45. The driven gear 464 corresponding to the first connecting rod 44 meshes with the first gear 462, and the driven gear 464 corresponding to the second connecting rod 45 meshes with the second gear 463.

[0050] Once the counterweight has moved to the designated position, the first motor 461 starts and drives the first gear 462 to rotate. One side of the first gear 462 drives the driven gear 464 on the first connecting rod 44 to rotate, and the other side sequentially drives the second gear 463 and the driven gear 464 on the second connecting rod 45 to rotate, causing the first connecting rod 44 and the second connecting rod 45 to rotate in opposite directions, thus controlling the first baffle 42 and the second baffle 43 to rotate in opposite directions. After the first baffle 42 and the second baffle 43 come into contact, the moving hole 12 is sealed. The sealing components 4 are arranged in two opposing sets so that each of the first baffle 42 and the second baffle 43 can stably block the moving hole 12.

[0051] When the first connecting rod 44 controls the movement of the first baffle 42 and the second connecting rod 45 controls the movement of the second baffle 43, the first auxiliary rod 14 provides support for the first baffle 42 and the second auxiliary rod 15 provides support for the second baffle 43, thereby improving the stability of the first baffle 42 and the second baffle 43 during movement.

[0052] Reference Figure 4 and Figure 5The support assembly 3 includes a support plate 31 and a driving component 32. Support grooves 123 are provided on both the first baffle 121 and the second baffle 122. A driving cavity 16 is provided in the sandblasting box 1, and a driving hole 161 communicating with the support groove 123 is provided on the inner wall of the driving cavity 16. The support plate 31 is slidably connected in the driving hole 161. One end of the driving component 32 is connected to the support plate 31, and the other end is connected to the second gear 463. Both the first baffle 121 and the second baffle 122 are provided with rubber plates.

[0053] The driving component 32 includes a driving shaft 321 and a plurality of driving gears 322. The driving shaft 321 is rotatably connected in the driving cavity 16, and each driving gear 322 is coaxially mounted on the driving shaft 321. Each driving gear 322 corresponds to a support plate 31, and the driving gear 322 meshes with the support plate 31 at the corresponding position. One end of the control component 5 is connected to the second gear 463, and the other end is connected to the driving shaft 321.

[0054] The control assembly 5 includes a control shaft 51, a first bevel gear 52, and a second bevel gear 53. The control shaft 51 is coaxially fixed on the second gear 463 and extends into the drive cavity 16. The first bevel gear 52 is coaxially fixed on the control shaft 51 in the drive cavity 16, and the second bevel gear 53 is coaxially fixed on the drive shaft 321, and the second bevel gear 53 meshes with the first bevel gear 52.

[0055] The second gear 463 rotates, driving the control shaft 51 to rotate. The control shaft 51 drives the first bevel gear 52 to rotate, which in turn drives the second bevel gear 53 and the drive shaft 321 to rotate. The drive shaft 321 then drives each drive wheel to rotate, and each drive wheel drives the corresponding support plate 31 to move along the support hole, so that the support plate 31 is inserted into the corresponding first baffle 121 or second baffle 122. When the support plate 31 abuts against the bottom of the corresponding support groove 123, the support plate 31 can support the corresponding first baffle 121 or the corresponding second baffle 122.

[0056] Reference Figure 1 and Figure 6 A balance pipe 6 is connected to the sandblasting box 1. A blocking assembly 7 is installed in the balance pipe 6. The blocking assembly 7 includes a cover plate 71 and several sealing plates 72. The cover plate 71 is slidably connected in the balance pipe 6. Each sealing plate 72 is rotatably connected in the balance pipe 6. A synchronization assembly 8 is installed in the balance pipe 6 for synchronously controlling the movement of the cover plate 71 and each sealing plate 72.

[0057] The synchronization assembly 8 includes a synchronization rod 81 and several synchronization blocks 82. A clearance cavity 61 is provided in the balance tube 6, and the synchronization rod 81 is slidably connected in the clearance cavity 61. Each synchronization block 82 is evenly fixed on the synchronization rod 81, and each synchronization block 82 corresponds to a sealing plate 72. Each sealing plate 72 extends into the clearance cavity 61 and is connected to the corresponding synchronization block 82 via a connector. A movable rod 711 is fixed on the cover plate 71, extending into the clearance cavity 61 and slidably connected to the inner wall of the clearance cavity 61. The synchronization rod 81 is connected to the movable rod 711.

[0058] Reference Figure 6 The connector includes a dovetail block 821. Each synchronization block 82 is provided with a dovetail block 821. The sealing plate 72 is provided with a dovetail groove 721 at one end of the relief cavity 61. The dovetail block 821 is slidably connected in the dovetail groove 721.

[0059] A synchronizing gear 611 is rotatably connected in the relief cavity 61. The synchronizing gear 611 meshes with the synchronizing rod 81, and a second motor 62 is fixed on the balance tube 6. The output end of the second motor 62 is coaxially fixed with the synchronizing gear 611.

[0060] After the first baffle 42 and the second baffle 43 close the moving hole 12, the second motor 62 starts and drives the synchronous gear 611 to rotate. The synchronous gear 611 then drives the synchronous rod 81 to move, and the synchronous rod 81 then drives each synchronous block 82 to move. The synchronous block drives the dovetail block 821 to move, so that the dovetail block 821 moves along the dovetail groove 721. At this time, the dovetail block 821 can control the corresponding sealing plate 72 to rotate. The synchronous rod 81 then drives the moving rod 711 and the cover plate 71 to move, so that the balance pipe 6 connects to the outside and the sandblasting box 1. When the shot blasting machine 111 is working, the sealing plates 72 can block the metal particles conveyed by the shot blasting machine 111, making it difficult for the metal particles to be discharged from the balance pipe 6 into the sandblasting box 1.

[0061] After the counterweight is processed, the first baffle 42 and the second baffle 43 are reset. At the same time, the second motor 62 reverses and drives the synchronous gear 611 to reverse, which in turn drives the synchronous rod 81 to reset. At this time, with the cooperation of the dovetail block 821 and the dovetail groove 721, when the synchronous rod 81 drives each synchronous block 82 to reset, it can drive the corresponding sealing plate 72 to reset, which provides convenience for the continued use of the sealing plate 72.

[0062] The implementation principle of the forklift counterweight surface treatment device according to this application embodiment is as follows: After the conveying component 2 moves the counterweight to the designated position, the sealing component 4 is activated and closes the moving hole 12. At the same time, the sealing component 4 drives the control component 5 to start, and the control component 5 then drives the support component 3 to start. The support component 3 then supports the first baffle 121 or the second baffle 122 at the corresponding position, improving the structural strength of the first baffle 121 and the second baffle 122. The sandblasting component 11 is activated and processes the counterweight. Each first baffle 121 and second baffle 122 cooperates with the sealing component 4 to provide double sealing for the moving hole 12, making it difficult for the metal particles sprayed by the sandblasting component 11 to be discharged from the moving hole 12 during operation. This allows the sandblasting component 11 to process the counterweight more stably, thereby improving the efficiency of the processing device in processing the counterweight.

[0063] This application also discloses a processing technology for a forklift balance weight surface treatment device, including the following steps:

[0064] Conveying component 2 conveys the counterweight to the sandblasting box 1, and sealing component 4 seals the moving hole 12;

[0065] The enclosed component 4 drives the control component 5 to control the support component 3 to support the first baffle 121 or the second baffle 122 at the corresponding position;

[0066] The sandblasting component 11 performs sandblasting treatment on the counterweight block.

[0067] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
