Description

Technical fields:

[0001] This utility model relates to the technical field of roller coating devices, and more specifically to an automatic roller coating device. Background technology:

[0002] In the production of rollers, rubber coating is the final and crucial step. However, current technology often relies on manual labor with hand tools. The process involves a tower crane placing the roller on a workbench, while workers manually cut the rubber sheet and apply the coating by hand-tapping. Existing coating equipment has low automation; the rotation and coating process are almost entirely manual, resulting in low efficiency. The pressure applied during coating is also manual, leading to inconsistent quality and significant errors. In some production scenarios, rubber coating is achieved by manually tapping the rubber sheet surface with a hand-held rubber hammer. This requires human coordination, and if the tapping angle is inaccurate, there is a risk of injury from the rubber hammer, posing a safety hazard. Utility Model Content:

[0003] To address the aforementioned problems and overcome the shortcomings of existing technologies, this utility model proposes to provide an automatic roller coating device that can automatically coat the rubber and reduce inconsistent coating quality caused by human error.

[0004] To achieve the above objectives, the present invention provides an automatic roller coating device, comprising a support mechanism and a pressing mechanism. The support mechanism includes a frame and at least two spaced rollers, which are rotatably mounted on the upper part of the frame and driven by an external power device. The pressing mechanism includes a coating pressure roller for pressing the rubber sheet against the roller, which is located outside the roller that drives the rubber sheet downward.

[0005] Furthermore, the rollers located on the upper part of the frame are preferably provided with two flat rollers, and the two flat rollers are preferably cylindrical first flat rollers and second flat rollers.

[0006] Furthermore, the rubber-coating roller is a cylindrical first rubber-coating roller. The first rubber-coating roller is connected to the machine frame via a cylinder.

The two ends of the first rubber-coating roller are rotatably connected to the ends of the cylinder piston rods. The two cylinders are inclined toward the rollers. The first flat roller, the second flat roller, and the first rubber-coating roller are parallel to each other.

[0007] Furthermore, the rollers disposed on the upper part of the frame are preferably provided with two concave rollers, namely a first concave roller and a second concave roller; the concave angle of the first concave roller and the second concave roller is β1.

[0008] Furthermore, the rubber-coated pressure roller is a two-section second rubber-coated pressure roller with a central hinge. The second rubber-coated pressure roller includes a fixed roller in the core and a rotating roller layer sleeved outside the fixed roller. The rotating roller layer rotates in conjunction with the fixed roller. The second rubber-coated pressure roller is connected to the frame via cylinders. The two cylinders are parallel and their bottoms are fixedly connected to the frame. The two ends of the fixed roller of the second rubber-coated pressure roller are rotatably connected to the ends of the piston rods of the cylinders. The two cylinders are inclined toward the roller. The included angle between the two sections of the second rubber-coated pressure roller opens downwards, and the included angle is β2. β1 = β2.

[0009] Furthermore, the rollers located on the upper part of the frame are preferably provided with two convex rollers, namely a first convex roller and a second convex roller; the convex angle of the first convex roller and the second convex roller is α1.

[0010] Furthermore, the rubber-coated pressure roller is a two-section second rubber-coated pressure roller with a central hinge.

The included angle between the two sections of the second rubber-coated pressure roller opens upward, and the included angle is α2. α1 = α2.

[0011] Furthermore, the rollers are respectively connected to the frame via bearing seats and respectively connected to the motor via reduction gears.

[0012] The beneficial effects of this utility model are as follows: The coating device provided by this utility model can solve the problem of automatic bonding between the rubber sheet and the roller by setting rollers and coating pressure rollers; the rollers are connected to the motor through a reduction mechanism, and the rotation of the rollers can drive the rotation of the rollers; the coating pressure rollers are connected to the piston rod of the cylinder, and when the piston rod of the cylinder extends, the coating pressure rollers coincide with the rollers in the vertical direction, which will inevitably squeeze the rubber sheet tightly against the rollers.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in more detail below with reference to the accompanying drawings.

[0029] In the description of this utility model, it should be understood that the description indicating the orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] A concave roller is a roller with a large diameter at both ends and a small diameter in the middle, while a convex roller is a roller with a small diameter at both ends and a large diameter in the middle. The cross-section of both concave and convex rollers perpendicular to their central axis is circular.

[0032] An automatic roller coating device includes a support mechanism and a pressing mechanism. The support mechanism includes a frame 5 and at least two spaced rollers. The rollers are rotatably mounted on the upper part of the frame 5 and are driven by an external power unit. The pressing mechanism includes a coating pressure roller for pressing the rubber sheet against the roller. The coating pressure roller is located outside the roller that drives the rubber sheet downward. The rollers are connected to the frame 5 via bearing seats and to a motor via a reduction gear mechanism.

[0033] The rollers are used to support the roller to be coated. Under the weight of the roller, there is a very large friction between the rollers and the roller, which enables the roller to drive the roller to rotate. The rollers are all connected to a power unit, which can provide sufficient power for the rotation of the roller and also prevent slippage between the roller and the roller due to the insertion of the rubber sheet. The beginning of the contact between the rubber sheet and the roller is on the side of the roller close to the coating pressure roller. The coating pressure roller presses the rubber sheet and the roller together. At the same time, the roller continues to rotate under the drive of the roller, so that the rubber sheet can be wrapped around the roller once and adhered to the outer wall of the roller.

[0034] Example 1

[0035] As attached Figure 1-4 As shown, the rollers set on the upper part of the frame 5 are preferably two flat rollers, and the two flat rollers are preferably cylindrical first flat roller 1 and second flat roller 2.

[0036] The rubber-coating roller is a cylindrical first rubber-coating roller 3. The first rubber-coating roller 3 is connected to the frame 5 through a cylinder 4. The two cylinders 4 are parallel and the bottom of the cylinder is fixedly connected to the frame 5 respectively. The two ends of the first rubber-coating roller 3 are rotatably connected to the ends of the piston rods of the cylinders 4 respectively. The two cylinders 4 are inclined towards the rollers. The first flat roller 1, the second flat roller 2, and the first rubber-coating roller 3 are parallel to each other.

[0037] When the roller is a flat roller, the first rubber-coating pressure roller 3 that cooperates with it is cylindrical. The first flat roller 1, the second flat roller 2, and the first rubber-coating pressure roller 3 are parallel to each other. This combination is suitable for coating cylindrical rollers. The two ends of the first rubber-coating pressure roller 3 are respectively connected to the ends of the piston rods of the cylinders 4 in a rotatable manner. The two cylinders 4 are inclined towards the roller. The distance between the first rubber-coating pressure roller 3 and the roller is adjusted by the forward-extending cylinder rods of the cylinders 4.

[0038] Example 2

[0039] As attached Figure 5-8 As shown, the rollers disposed on the upper part of the frame 5 are preferably provided with two concave rollers, namely a first concave roller 701 and a second concave roller 702; the concave angle of the first concave roller 701 and the second concave roller 702 is β1.

[0040] The roller is a concave roller, which is suitable for coating convex rollers with small diameters at both ends and large diameters in the middle. The convex roller is placed on the concave roller, and the concave and convex fit together. The surface of the convex roller is in line contact with the surface of the concave roller. Under the action of the convex roller's own weight, the concave roller provides sufficient friction for the rotation of the convex roller.

[0041] The rubber-coated pressure roller is a two-section second rubber-coated pressure roller 6 with a central hinge. The second rubber-coated pressure roller 6 includes a fixed roller 62 in the core and a rotating roller layer 61 sleeved on the outside of the fixed roller 62. The rotating roller layer 61 is rotatably engaged with the fixed roller 62. The second rubber-coated pressure roller 6 is connected to the frame 5 through cylinders 4. The two cylinders 4 are parallel and their bottoms are fixedly connected to the frame 5. The two ends of the fixed roller 62 of the second rubber-coated pressure roller 6 are rotatably connected to the ends of the piston rods of the cylinders 4. The two cylinders 4 are inclined toward the roller. The included angle between the two sections of the second rubber-coated pressure roller 6 opens downward and the included angle is β2. β1 = β2.

[0042] The two sections of the second rubber-coating pressure roller 6 are hinged together in the middle. The included angle between the two sections of the second rubber-coating pressure roller 6 can be adjusted as needed. When the included angle between the two sections of the second rubber-coating pressure roller 6 is adjusted so that the opening faces downward and the included angle is equal to that of the concave roller, the surface of the second rubber-coating pressure roller 6 is in line contact with the surface of the convex roller when coating the convex roller, which can fully compress the rubber sheet and adhere it to the surface of the convex roller. The rotating roller layer 61 of the second rubber-coating pressure roller 6 rotates and cooperates with the fixed roller 62, which ensures that the surface of the second rubber-coating pressure roller 6 and the surface of the convex roller are in rolling friction, making operation more labor-saving.

[0043] Example 3

[0044] like Figure 9-13 As shown, the rollers set on the upper part of the frame 5 are preferably provided with two convex rollers, namely a first convex roller 801 and a second convex roller 802; the convex angle of the first convex roller 801 and the second convex roller 802 is α1.

[0045] The roller is a convex roller, which is suitable for coating concave rollers with large diameters at both ends and small diameters in the middle. The concave roller is placed on the convex roller, and the concave and convex fit together. The surface of the concave roller is in line contact with the surface of the convex roller. Under the action of the concave roller's own weight, the convex roller provides sufficient friction for the rotation of the concave roller.

[0046] The rubber-coated pressure roller is a two-section second rubber-coated pressure roller 6 with a central hinge. The second rubber-coated pressure roller 6 includes a fixed roller 62 in the core and a rotating roller layer 61 sleeved outside the fixed roller 62. The rotating roller layer 61 is rotatably engaged with the fixed roller 62. The second rubber-coated pressure roller 6 is connected to the frame 5 through cylinders 4. The two cylinders 4 are parallel and their bottoms are fixedly connected to the frame 5. The two ends of the fixed roller 62 of the second rubber-coated pressure roller 6 are rotatably connected to the ends of the piston rods of the cylinders 4. The two cylinders 4 are inclined toward the roller. The included angle between the two sections of the second rubber-coated pressure roller 6 opens upward, and the included angle is α2. α1 = α2.

[0047] The included angle between the two sections of the second rubber-coating roller 6 is adjusted so that the opening faces upwards, and the included angle is equal to that of the convex roller. This ensures that when coating the concave roller, the surface of the second rubber-coating roller 6 is in line contact with the surface of the concave roller, allowing for thorough pressing and adhesion of the rubber sheet to the concave roller surface. Similarly, the rotating roller layer 61 of the second rubber-coating roller 6 rotates in conjunction with the fixed roller 62, ensuring that the surface of the second rubber-coating roller 6 and the surface of the concave roller experience rolling friction, resulting in less effort during operation.

[0048] Except for the technical features described in the specification, all of these are technologies known to those skilled in the art.
