Description

Technical Field

[0001] This utility model relates to the field of material feeding technology for roller coating machines, and more specifically, to a material feeding mechanism for a roller coating machine. Background Technology

[0002] Roller coaters are typically equipped with paint storage devices and conveying systems. Paint is conveyed from the storage device to the roller coater's distribution system via pipes or pumps. The distribution system's function is to evenly distribute the paint across the roller surface, ensuring uniform paint application when the roller contacts the workpiece. The roller is the core component of the roller coater; it is driven to rotate by a motor or other power source. As the roller rotates, paint adheres to its surface under centrifugal force and is then transferred to the workpiece through contact between the roller and the workpiece.

[0003] In existing roller coating machines, a feeding mechanism is required at the discharge port to receive materials. This feeding mechanism mainly consists of a guard plate, a drive mechanism, a drive roller, and a conveyor belt. The feeding mechanism is placed at the bottom of the discharge port of the roller coating machine to transport the materials. To facilitate changing the direction of the feeding mechanism for transport in different directions, a cylinder is used to drive a corner of the device. However, due to the limited length of the cylinder, the device can only be rotated to a certain angle, which is limited. Furthermore, when the cylinder is driven, it needs to be placed horizontally on one side of the device, and its direction needs to be perpendicular to the overall direction of the device. This results in the device occupying a large space and being unable to adapt to all feeding situations. Therefore, it needs to be modified and optimized. Utility Model Content

Compared with the traditional device, this device drives the protrusion to rotate after starting motor one, and then drives the rotating plate to rotate, thereby driving the rotating base plate to rotate. Compared with the traditional device, the device has a larger rotation angle by cylinder push, which can adapt to more working conditions, reduce the space occupied by the device, and can be rotated to any position at will, thereby improving the working efficiency of the device.

[0018] 2. In this disclosure, rotating the handle drives the threaded rod to rotate, which in turn moves the threaded block, thereby moving the lower pressure roller and tensioning the conveyor belt. Compared to traditional devices, this device tensions the conveyor belt downwards by moving the lower pressure roller. Traditional devices are prone to slackness during use, leading to slippage at the connection with the drive roller and preventing rotation. This device, by moving the conveyor belt, increases its tension, preventing slippage between the belt and drive roller, thus increasing friction between them and improving transmission efficiency.

[0030] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0031] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0032] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0033] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0034] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0035] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] like Figures 1 to 9 As shown, this utility model provides a material feeding mechanism for a roller coating machine, including a wheel 1 and a base plate 2, with the base plate 2 fixedly disposed above the wheel 1;

[0037] The bottom of the base plate 2 has a groove 11. A motor 12 is fixedly installed on one side inside the groove 11. A bevel gear 13 is fixedly installed above the drive shaft of the motor 12. A bevel gear 14 is rotatably installed on the top of the inner side of the groove 11. A protrusion 15 is fixedly installed on the top of the bevel gear 14. The top of the protrusion 15 extends to the outer side of the base plate 2 and a rotating plate 16 is fixedly installed thereon. A rotating base plate 3 is fixedly installed on the top of the rotating plate 16. The rotating plate 16 is movably connected to the base plate 2. The bevel gear 13 and the bevel gear 14 mesh with each other. A heat dissipation hole 17 is opened on one side of the bottom of the base plate 2 and extends into the inside of the groove 11.

[0038] When the operator uses the device, they first start the motor 12 via the controller 32. When the motor 12 starts, it drives the bevel gear 13 to rotate. When the bevel gear 13 rotates, it meshes with the bevel gear 14. As the bevel gear 13 rotates, it drives the bevel gear 14 to rotate. When the bevel gear 14 rotates, it drives the protrusion 15 to rotate. When the protrusion 15 rotates, it drives the rotating plate 16 to rotate. When the rotating plate 16 rotates, it drives the rotating base plate 3 to rotate, thereby driving the upper part of the device to rotate.

[0039] The controller 32 starts the motor 12, which drives the rotation of the bevel gear 13, which in turn drives the rotation of the bevel gear 14, which in turn drives the cam 15, the rotating plate 16 and the upper part of the device to rotate in sequence. Compared with the traditional device, this device drives the cam 15 to rotate after starting the motor 12, which in turn drives the rotation of the rotating plate 16, thereby driving the rotation of the rotating base plate 3. Compared with the traditional device, the device can rotate at a larger angle by means of cylinder push, which can adapt to more working conditions, reduce the space occupied by the device, and can be rotated to any position at will, thereby improving the working efficiency of the device.

[0040] Among them, a base block 4 is fixedly installed above the rotating base plate 3, and two guard plates 5 are fixedly installed above the base block 4. A fixing plate 18 and a fixing plate 29 are fixedly installed on one side of each of the two guard plates 5. The fixing plate 29 is located below the fixing plate 18. A threaded rod 21 is rotatably installed between the fixing plate 18 and the fixing plate 29. A handle 20 is rotatably installed on the top of the fixing plate 18. The bottom of the handle 20 passes through the upper and lower sides of the fixing plate 18 and is fixedly connected to the threaded rod 21. A threaded block 22 is threadedly sleeved on the outer surface of the threaded rod 21. A pressure roller 23 is rotatably installed on one side of the threaded block 22. A limit post 24 is fixedly installed between the other fixing plate 18 and the fixing plate 29. One end of the pressure roller 23 is movably sleeved with the limit post 24.

[0041] When the operator uses the device, they first turn the handle 20. When the handle 20 turns, it drives the threaded rod 21 to turn. When the threaded rod 21 turns, since the threaded rod 21 and the threaded block 22 are threadedly connected, and the rotation of the threaded block 22 is restricted by the limit post 24, the rotation of the threaded rod 21 will drive the threaded block 22 to move. When the threaded block 22 moves, it will drive the pressure roller 23 to move. When the pressure roller 23 moves, it will drive the conveyor belt 29 to be tensioned.

[0042] By rotating the handle 20, the threaded rod 21 rotates, causing the threaded block 22 to move, which in turn moves the pressure roller 23, thus tensioning the conveyor belt 29. Compared to conventional devices, this device tensions the conveyor belt 29 downwards by moving the pressure roller 23 downwards. In contrast, conventional devices are prone to slackness during use, leading to slippage at the connection with the drive roller 28 and preventing rotation. This device, by moving the conveyor belt 29, increases its tension, preventing slippage between the conveyor belt 29 and the drive roller 28, thereby increasing the friction between them and improving transmission efficiency.

[0043] Among them, two side plates 6 are fixedly installed on the upper part of the guard plate 5, and are evenly distributed on the upper part of the two guard plates 5.

[0044] The side plate 6 is designed to support the bottom of the bracket 7, thereby improving the stability of the bracket 7.

[0045] A bracket 7 is fixedly installed on the top of the side plate 6, and the two ends of the bottom of the bracket 7 are fixedly connected to the top of the two side plates 6 respectively.

[0046] The bracket 7 is designed to support the bottom of the double-headed cylinder 8, thereby improving the stability of the double-headed cylinder 8 itself.

[0047] Among them, a double-headed cylinder 8 is fixedly installed on the top of the bracket 7, and a movable plate 9 is fixedly installed at the bottom of both ends of the double-headed cylinder 8. The bottom of the movable plate 9 passes through the upper and lower sides of the bracket 7.

[0048] The controller 32 starts the double-headed cylinder 8 to drive the two moving plates 9 to move, thereby limiting the objects transported above the conveyor belt 29.

[0049] Among them, a roller 10 is fixedly installed on one side of the movable plate 9, and the roller 10 is located below the bracket 7.

[0050] Among them, a motor bracket 25 is fixedly installed on one side of the guard plate 5, and a motor 26 is fixedly installed on one side of the motor bracket 25. The drive shaft of the motor 26 passes through the left and right sides of the guard plate 5 and a drive roller 28 is fixedly installed thereon. There are two drive rollers 28, and a conveyor belt 29 is connected between the two drive rollers 28. The conveyor belt 29 is movably connected to the lower pressure wheel 23.

[0051] The controller 32 starts the motor 26 to drive the rotating frame 27 to rotate. When the rotating frame 27 rotates, it drives the drive roller 28 to rotate, thereby driving the conveyor belt 29 to rotate.

[0052] A guide plate 30 is fixedly installed between the two guard plates 5, and one end of the guide plate 30 is movably connected to the conveyor belt 29.

[0053] The guide plate 30 is designed to guide the transported items, making it easier to move the items above the conveyor belt 29.

[0054] Among them, a limiting roller 31 is rotatably installed between the two guard plates 5. The limiting roller 31 is located at the bottom of the conveyor belt 29 and is movably connected to the conveyor belt 29.

[0055] The design of the limiting roller 31 can prevent the contact area between the conveyor belt 29 and the drive roller 28 from becoming smaller, thus avoiding slippage.

[0056] Among them, a controller 32 is fixedly installed on one side of the guard plate 5. The controller 32 is electrically connected to the double-headed cylinder 8, the motor 12 and the motor 26.

[0057] The controller 32 is designed to control the operation of the device and improve the safety of the device operation.

[0058] Working principle and usage process of this utility model:

[0059] When the operator uses the device, they first start the motor 12 via the controller 32. When the motor 12 starts, it drives the bevel gear 13 to rotate. When the bevel gear 13 rotates, it meshes with the bevel gear 14. As the bevel gear 13 rotates, it drives the bevel gear 14 to rotate. When the bevel gear 14 rotates, it drives the protrusion 15 to rotate. When the protrusion 15 rotates, it drives the rotating plate 16 to rotate. When the rotating plate 16 rotates, it drives the rotating base plate 3 to rotate, thereby driving the upper part of the device to rotate.

[0060] When the operator uses the device, they first turn the handle 20. When the handle 20 turns, it drives the threaded rod 21 to turn. When the threaded rod 21 turns, since the threaded rod 21 and the threaded block 22 are threadedly connected, and the rotation of the threaded block 22 is restricted by the limit post 24, the rotation of the threaded rod 21 will drive the threaded block 22 to move. When the threaded block 22 moves, it will drive the pressure roller 23 to move. When the pressure roller 23 moves, it will drive the conveyor belt 29 to be tensioned.
