Description

Technical Field

[0001] This application relates to the field of sandblasting equipment technology, and in particular to a feeding mechanism suitable for sandblasting long columnar materials. Background Technology

[0002] Sandblasting, a widely used surface treatment process, uses compressed air to propel materials such as copper ore sand and quartz sand onto the workpiece surface through a high-speed jet, thereby changing the surface morphology of the workpiece. It plays an important role in many fields such as machinery manufacturing and aerospace.

[0003] In existing technologies, smaller parts are often placed directly inside the sandblasting chamber for sandblasting. For long cylindrical materials, a feeding mechanism is typically used to transport them to the sandblasting chamber for sandblasting. A common feeding mechanism is a conveyor belt.

[0004] However, since the conveyor belt can only achieve straight-line conveying in one direction, if it is necessary to perform all-round sandblasting on long cylindrical materials, workers need to adjust the posture of the workpiece multiple times and repeatedly send the workpiece into the sandblasting chamber for sandblasting. This reduces the sandblasting efficiency of long cylindrical materials and has obvious shortcomings. Utility Model Content

[0005] In order to improve the sandblasting efficiency of long columnar materials, this application provides a feeding mechanism suitable for sandblasting long columnar materials.

[0006] This application provides a technical solution for a feeding mechanism suitable for sandblasting long columnar materials, using the following approach:

[0007] A feeding mechanism for sandblasting cylindrical long materials includes a frame, a sandblasting chamber for sandblasting is provided on the frame, a feed port is provided on one side of the sandblasting chamber, a cylindrical workpiece is slidably connected to the frame, an auxiliary feeding component and a tilting component are provided on the frame, the tilting component includes a first motor mounted on the frame, the output shaft of the first motor is connected to a tilting shaft via a pulley and belt drive, the tilting shaft is arranged along the length direction of the frame and rotatably connected to the frame, a plurality of tilting wheels are coaxially fixedly arranged on the tilting shaft along the length direction, the tilting wheels abut against the outer surface of the workpiece, and when the workpiece is tilted, the auxiliary feeding component drives the workpiece to move along the axis.

[0008] By adopting the above technical solution, during sandblasting, the worker places the workpiece on the side of the frame near the feed inlet, and then starts the first motor. The first motor drives the rotating shaft to rotate through the pulley and belt. The rotating shaft drives multiple rotating wheels to rotate synchronously. The rotating wheels drive the workpiece to rotate through friction. At the same time, the auxiliary feeding component drives the workpiece to move along the axis, thereby realizing the rotation of the columnar workpiece while it is being conveyed. This allows the workpiece to be sandblasted from all directions in the sandblasting chamber without the need for manual adjustment of the rotation, thus improving the sandblasting efficiency of long columnar materials.

[0009] Optionally, the auxiliary feeding assembly includes a feeding plate disposed on the side of the frame away from the tilting shaft. The length direction of the feeding plate is parallel to the axis of the tilting shaft. The feeding plate is provided with multiple mounting brackets, and each mounting bracket is rotatably connected to a feeding wheel. The end of the feeding wheel abuts against the outer surface of the workpiece. The axes of each feeding wheel are parallel to each other, and the angle between the axis of the feeding wheel and the axis of the tilting shaft in the counterclockwise direction is an acute angle.

[0010] By adopting the above technical solution, since the axis of the feeding wheel is set at an inclination relative to the axis of the flipping shaft, when the flipping wheel drives the workpiece to rotate, the friction between the feeding wheel and the workpiece will generate a component force along the axis of the workpiece. This component force drives the workpiece to be conveyed along the axis, thus realizing the synchronous conveying and flipping of the workpiece, and the structure is simple.

[0011] Optionally, each of the mounting brackets is detachably connected to the feed plate by a plurality of connecting bolts.

[0012] By adopting the above technical solution, the setting of connecting bolts enables the detachable installation of the feeding wheel on the feeding plate, allowing the installation position of the feeding wheel to be flexibly adjusted according to the different specifications and sizes of cylindrical long materials, improving the applicability of the feeding mechanism, and at the same time facilitating the daily maintenance and replacement of the feeding wheel, and improving the convenience of worker operation.

[0013] Optionally, the frame is provided with an adjustment component, which drives the feed plate to slide along the radial direction of the workpiece.

[0014] By adopting the above technical solution, before sandblasting, the worker can drive the feeding plate to slide along the radial direction of the workpiece by adjusting the component, thereby changing the distance between the feeding wheel and the turning wheel to suit columnar workpieces of different diameters. This ensures that the feeding wheel and the turning wheel can maintain good contact and fit with the surface of workpieces of different diameters, further improving the applicability of the feeding mechanism.

[0015] Optionally, the adjustment assembly includes a second motor mounted on the frame. The output shaft of the second motor is connected to an adjustment shaft via a pulley and belt drive. Multiple gears are coaxially mounted on the adjustment shaft. A rack plate corresponding to each of the multiple gears is mounted on the bottom surface of the feeding plate. The rack plate meshes with the corresponding gear. Guide grooves are provided on the opposite inner sidewalls of the frame. The guide grooves are parallel to the radial direction of the workpiece. Both ends of the feeding plate are slidably connected in the guide grooves.

[0016] By adopting the above technical solution, the worker places the workpiece on the frame and makes one end of the workpiece abut against the turning wheel. Then, the second motor is started. The second motor drives the adjusting shaft to rotate through the pulley and belt. The adjusting shaft drives multiple gears to rotate synchronously. When the gears rotate, they drive the meshing rack plate to move. The rack plate drives the feeding plate and feeding wheel to move along the guide groove toward the workpiece until the feeding wheel abuts against the outer surface of the workpiece. In this way, the position of the feeding plate can be adjusted adaptively according to workpieces of different diameters, improving the applicability of the feeding mechanism and meeting diverse production needs.

[0017] Optionally, the second motor is a forward and reverse reversible brake motor.

[0018] By adopting the above technical solution, the brake function of the forward and reverse motor can quickly brake when the second motor stops rotating, avoiding the situation where the feeding wheel is separated from the workpiece due to inertia or mechanical vibration, thereby ensuring the friction between the feeding wheel and the reversing wheel and the workpiece, and ensuring the stable conveying and reversing of the workpiece during the sandblasting process.

[0019] Optionally, a plurality of the tilting wheels and the feeding wheels are evenly and equidistantly arranged along the length of the frame.

[0020] By adopting the above technical solution, the evenly distributed flipping wheels ensure that the workpiece is subjected to consistent force in all parts during the flipping process, avoiding workpiece deformation or flipping jam caused by uneven force. The evenly arranged feeding wheels can provide balanced driving force for the workpiece, preventing the workpiece from deviating or tilting when moving axially, and ensuring that the workpiece is transported smoothly along the preset trajectory.

[0021] Optionally, each of the rotating wheels is provided with a friction ring on its outer surface, and the friction ring abuts against the outer surface of the workpiece.

[0022] By adopting the above technical solution, the friction ring abuts against the outer surface of the workpiece, which effectively increases the friction between the turning wheel and the workpiece, making the turning wheel more stable when turning the workpiece and reducing the possibility of slippage.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. This application sets up a flipping component and an auxiliary feeding component. The flipping component and the auxiliary feeding component enable the columnar workpiece to be flipped while being conveyed, so that the workpiece can be sandblasted in all directions in the sandblasting chamber without the need for manual adjustment of the flipping, thus improving the sandblasting efficiency of columnar long material workpieces.

[0025] 2. By setting an adjustment component, before sandblasting, the worker drives the feeding plate to slide along the radial direction of the workpiece, thereby changing the distance between the feeding wheel and the turning wheel to suit cylindrical workpieces of different diameters. This ensures that the feeding wheel and the turning wheel can maintain good contact and fit with the surface of workpieces of different diameters, thus improving the applicability of the feeding mechanism.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0031] This application discloses a feeding mechanism suitable for sandblasting long columnar materials.

[0032] Reference Figure 1 and Figure 2 A feeding mechanism for sandblasting cylindrical long materials includes a frame 1, a sandblasting chamber 2 fixedly connected to the frame 1, a feed port 21 communicating with the interior on one side of the sandblasting chamber 2, a workpiece 01 to be sandblasted placed on the frame 1, the workpiece 01 being a cylindrical long material, and a sandblasting device (not shown in the figure) for sandblasting installed inside the sandblasting chamber 2. The sandblasting principle is existing technology and will not be described in detail here.

[0033] Reference Figure 1 and Figure 2The frame 1 is equipped with a tilting assembly 3 and an auxiliary feeding assembly 4. The tilting assembly 3 includes a first motor 31 fixedly installed at the bottom of the frame 1. The output shaft of the first motor 31 is connected to a tilting shaft 32 via a pulley and belt drive. The tilting shaft 32 is located inside the sandblasting chamber 2 and is rotatably connected to the upper surface of the frame 1. The axis of the tilting shaft 32 is parallel to the length direction of the frame 1. Multiple tilting wheels 33 are coaxially fixedly connected to the tilting shaft 32 along the length direction. Each tilting wheel 33 has a friction ring 331 fixedly connected to its outer surface to increase friction. The friction ring 331 abuts against the outer surface of one side of the workpiece 01.

[0034] Reference Figure 1 and Figure 2 The auxiliary feeding assembly 4 includes a feeding plate 41 disposed on the side of the frame 1 away from the tilting shaft 32. Both the feeding plate 41 and the tilting shaft 32 are disposed inside the sandblasting chamber 2. The length direction of the feeding plate 41 is parallel to the axis of the tilting shaft 32. Multiple mounting brackets 42 are mounted on the feeding plate 41 along its length direction. Multiple feeding wheels 43 are rotatably connected to each mounting bracket 42. Each mounting bracket 42 is detachably connected to the feeding plate 41 by multiple connecting bolts 5. In this embodiment, there are four connecting bolts 5, which are respectively disposed at the four corners of the mounting bracket 42. The setting of the connecting bolts 5 enables the detachable installation of the feeding wheels 43 on the feeding plate 41, so that the installation position of the feeding wheels 43 can be flexibly adjusted according to the columnar long materials of different specifications and sizes.

[0035] Reference Figure 1 and Figure 2 The end of the feeding wheel 43 near the workpiece 01 abuts against the outer surface of the workpiece 01. The axes of each feeding wheel 43 are parallel to each other, and the angle between the axis of the feeding wheel 43 and the axis of the flipping shaft 32 in the counterclockwise direction is an acute angle.

[0036] During sandblasting, the worker places the workpiece 01 on the side of the frame 1 near the feed inlet 21, and then starts the first motor 31. The first motor 31 drives the rotating shaft 32 to rotate through the pulley and belt. The rotating shaft 32 drives multiple rotating wheels 33 to rotate synchronously. The rotating wheels 33 drive the workpiece 01 to rotate through the friction between the friction ring 331 and the outer surface of the workpiece 01. Since the axis of the feeding wheel 43 is inclined relative to the axis of the rotating shaft 32, when the rotating wheel 33 drives the workpiece 01 to rotate, the friction between the feeding wheel 43 and the workpiece 01 will generate a component force along the axis of the workpiece 01. This component force drives the workpiece 01 to be conveyed along the axis, thereby realizing the rotation of the columnar workpiece 01 while it is being conveyed. This allows the workpiece 01 to be sandblasted in all directions in the sandblasting chamber 2 without the need for manual adjustment of the rotation, thus improving the sandblasting efficiency of the columnar long material workpiece 01.

[0037] Reference Figure 1 and Figure 2 To ensure stable conveying and flipping of workpiece 01 during sandblasting, multiple flipping wheels 33 are evenly spaced along the length of the flipping shaft 32, so that the workpiece 01 is subjected to consistent force in all parts during flipping, avoiding deformation or jamming of workpiece 01 due to uneven force. Multiple feeding wheels 43 are evenly spaced along the length of the feeding plate 41, and the evenly arranged feeding wheels 43 provide balanced driving force for workpiece 01, preventing workpiece 01 from shifting or tilting when moving axially.

[0038] Reference Figure 2 and Figure 3 In order to make the feeding mechanism suitable for workpieces 01 of different diameters, an adjustment component 6 is provided on the frame 1. The adjustment component 6 drives the feeding plate 41 to slide along the radial direction of the workpiece 01. Specifically, the adjustment component 6 includes a second motor 61 fixedly installed at the bottom of the frame 1. The second motor 61 is a forward and reverse brake motor. The output shaft of the second motor 61 is connected to the adjustment shaft 62 through a pulley and belt drive. The brake function enables the second motor 61 to stop rotating quickly, so as to avoid the automatic rotation of the adjustment shaft 62 due to inertia or mechanical vibration.

[0039] Reference Figure 2 and Figure 3 The adjusting shaft 62 is rotatably connected inside the frame 1 and located below the feeding plate 41. The axis of the adjusting shaft 62 is parallel to the length direction of the feeding plate 41. Multiple gears 63 are coaxially fixedly connected to the adjusting shaft 62 along the length direction. The multiple gears 63 are evenly and equidistantly arranged. A rack plate 64 corresponding to each of the multiple gears 63 is fixedly connected to the bottom surface of the feeding plate 41. The rack plate 64 is parallel to the radial direction of the workpiece 01 and is meshed with the corresponding gear 63.

[0040] Reference Figure 2 and Figure 3 Guide grooves 101 are provided on the inner sidewalls of the frame 1 along the length direction. The guide grooves 101 are parallel to the radial direction of the workpiece 01. Both ends of the feeding plate 41 are slidably connected in the guide grooves 101. The opening of the guide grooves 101 improves the stability of the movement of the feeding plate 41.

[0041] Before sandblasting, the worker places the workpiece 01 on the frame 1 and makes one end of the workpiece 01 abut against the tilting wheel 33. Then, the second motor 61 is started. The second motor 61 drives the adjusting shaft 62 to rotate through the pulley and belt. The adjusting shaft 62 drives multiple gears 63 to rotate synchronously. When the gears 63 rotate, they drive the meshing rack plate 64 to move. The rack plate 64 drives the feeding plate 41 and the feeding wheel 43 to move along the guide groove 101 toward the workpiece 01 until the feeding wheel 43 abuts against the outer surface of the workpiece 01. In this way, the position of the feeding plate 41 can be adjusted according to the different diameter workpieces 01, ensuring that the feeding wheel 43 and the tilting wheel 33 can maintain good contact and fit with the surface of workpieces 01 of different diameters, thus improving the applicability of the feeding mechanism.

[0042] The implementation principle of a feeding mechanism for sandblasting cylindrical long materials in this application embodiment is as follows: During sandblasting, the worker places the workpiece 01 on the side of the frame 1 near the feed inlet 21, and then starts the first motor 31. The first motor 31 drives the rotating shaft 32 to rotate through the pulley and belt. The rotating shaft 32 drives multiple rotating wheels 33 to rotate synchronously. The rotating wheels 33 drive the workpiece 01 to rotate through the friction between the friction ring 331 and the outer surface of the workpiece 01. Since the axis of the feeding wheel 43 is inclined relative to the axis of the rotating shaft 32, when the rotating wheel 33 drives the workpiece 01 to rotate, the friction between the feeding wheel 43 and the workpiece 01 will generate a component force along the axis of the workpiece 01. This component force drives the workpiece 01 to be conveyed along the axis, thereby realizing the rotation of the cylindrical workpiece 01 while being conveyed, so that the workpiece 01 can be sandblasted in all directions in the sandblasting chamber 2 without the need for manual adjustment of the rotation, thus improving the sandblasting efficiency of the cylindrical long material workpiece 01.

[0043] 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.
