Description

Technical Field

[0001] This utility model relates to the field of hygiene product manufacturing equipment technology, specifically to a drive wheel structure. Background Technology

[0002] In the production of disposable hygiene products such as baby diapers, baby pull-ups, and adult pants, materials need to be pulled by drive wheels when conveyed on the main line. In order to keep the product flat, a suction box is needed to hold the product. This requires connecting the drive wheel and the suction box through a conveyor belt. However, conventionally, the drive wheel and the suction box are fixed independently to the panel. When adjustments are needed, the drive wheel and the suction box need to be adjusted separately. Moreover, when using a wider suction box, a larger drive wheel is required. In the limited space, the drive wheel mounting base cannot be made large enough. This results in the drive wheel blocking the mounting hole, making the installation and adjustment of the drive wheel very inconvenient. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model provides a drive wheel structure to solve the problems of inconvenient adjustment and limited installation space caused by the independent fixing of the drive wheel and the intake box in the prior art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A drive wheel structure includes an air intake box, side plates, a drive wheel, bearings, and a coupling. The air intake box includes a fixed rod and a box body mounted on the fixed rod. Side plates are provided on both sides of the drive wheel. The drive wheel is mounted on the side plates through the bearings. Each side plate is connected to the fixed rod of the air intake box through a connecting component. The drive wheel is connected to an external drive device through the coupling.

[0006] Furthermore, the bearing is a deep groove ball bearing or a needle roller bearing.

[0007] Furthermore, the coupling is a universal coupling or a cross-slider coupling.

[0008] Furthermore, the connecting component includes:

[0009] The upper clamp and the lower clamp are provided with arc-shaped grooves on their inner walls that match the outer diameter of the fixing rod.

[0010] A connecting plate is fixedly disposed on the outside of the upper clamp or the lower clamp, and the connecting plate is provided with mounting holes for mounting the side plate;

[0011] At least two fastening bolts are used to lock the upper clamp and the lower clamp onto the fixing rod, and the fastening bolts are arranged in a centrally symmetrical manner.

[0012] At least two positioning pins are provided, and the upper clamp and the lower clamp are respectively provided with pin holes for the positioning pins to pass through. When the upper clamp and the lower clamp are attached to the fixed rod, the positioning pins pass through the pin holes.

[0013] Furthermore, the connecting plate is integrally formed or welded to the upper clamp, and a triangular reinforcing rib is provided at the connection between the connecting plate and the upper clamp.

[0014] Furthermore, the mounting holes on the connecting plate are elongated.

[0015] Furthermore, the arc-shaped groove surfaces of the inner walls of the upper and lower clamps are knurled.

[0016] Furthermore, each of the fastening bolts is equipped with an anti-loosening element, which is a flange anti-loosening nut, an elastic washer, or a wedge-shaped anti-loosening washer.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention integrates the drive wheel and the suction box into a single module by directly connecting the drive wheel side plate to the fixing rod of the suction box. When the work position needs to be adjusted, only the suction box needs to be moved, and the drive wheel will move synchronously accordingly, eliminating the need for tedious separate adjustments. This greatly simplifies the operation process and improves the adjustment efficiency of the production line. This structure avoids designing a large, independent mounting base for a large drive wheel in a limited panel space. By utilizing the inherent fixing rod of the suction box as the mounting base, it cleverly avoids the problem of the drive wheel's large size obstructing the mounting holes, making installation and adjustment in a compact space feasible and convenient. The fixed relative position of the drive wheel and the suction box ensures that the conveyor belt fitted on them is always in a stable tension and transmission state, avoiding belt deviation, wear, or slippage caused by improper separate adjustments, thereby ensuring the smoothness of product conveying and product quality.

[0031] The following will describe the implementation of this utility model in detail with reference to specific embodiments, so that the process of how this utility model uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0032] Example 1: As Figures 1 to 2 As shown, this embodiment provides a drive wheel structure for a disposable hygiene product production line. The drive wheel structure mainly includes an air intake box 1, a side plate 2, a drive wheel 3, a bearing 4, and a coupling 5.

[0033] The air intake box 1 consists of a fixed rod 11 and a box body 12 mounted on the fixed rod 11. A negative pressure chamber is formed inside the box body 12, and air intake holes for adsorbing materials are provided on its upper surface. The drive wheel 3 is arranged laterally, and its central shaft is supported between the side plates 2 on both sides by two deep groove ball bearings, so that the drive wheel 3 can rotate flexibly.

[0034] One end of the central shaft of the drive wheel 3 extends out of the side plate 2 and is connected to the main shaft of the external drive motor (not shown in the figure) through a universal coupling. The universal coupling can effectively compensate for the radial and angular deviations between the drive wheel 3 and the external drive motor caused by adjusting the position of the intake box 1, ensuring the continuity and stability of power transmission.

[0035] The key to this embodiment is that the drive wheel 3 is connected to the suction box 1 via the side plate 2. In this embodiment, by directly connecting the side plate 2 to the fixing rod 11 of the suction box 1, the drive wheel 3 and the suction box 1 are integrated into a single module. When the work position needs to be adjusted, only the suction box 1 needs to be moved, and the drive wheel 3 will move synchronously accordingly. There is no need to make tedious separate adjustments to the two. The structure provided by this embodiment avoids designing a large and independent mounting base 31 for the large drive wheel 3 in the limited panel space. By using the inherent fixing rod 11 of the suction box 1 as the mounting base, the problem of the large size of the drive wheel 3 blocking the mounting hole 32 is cleverly avoided.

[0036] In this embodiment, the side plate 2 and the fixing rod 11 are welded together. In other preferred embodiments, bolts can also be used for connection. These are all existing public connection methods and will not be described in detail here.

[0037] Example 2: Figures 3 to 5 The difference between this embodiment and Embodiment 1 is that the side plate 2 is directly fixed to the fixing rod 11 of the air intake box 1 by a dedicated connecting component 6. The connecting component 6 consists of an upper clamp 61, a lower clamp 62, a connecting plate 63, a fastening bolt 64, and a positioning pin 65. The inner walls of the upper clamp 61 and the lower clamp 62 are machined with arc-shaped grooves 66 that precisely match the outer diameter of the fixing rod 11. The connecting plate 63 and the upper clamp 61 are fixed together by welding, and a triangular reinforcing rib 67 is welded at the junction of the two, thereby significantly enhancing the ability of the connecting plate to resist the transmission torque from the drive wheel 3 and preventing its deformation.

[0038] The connecting plate 63 has an elongated mounting hole 68. The side plate 2 is fixed to the connecting plate by bolts passing through the elongated mounting hole 68. This elongated hole design allows the upper clamp 61 and lower clamp 62 to be locked onto the fixing rod 11 first during installation, and then the side plate 2 is connected to the connecting plate 63. The side plate 2, together with the entire drive wheel 3, can be finely adjusted in position along the axial direction of the fixing rod 11.

[0039] During installation, first place the lower clamp 62 in the predetermined position of the fixing rod 11, and then close the upper clamp 61 so that the arc-shaped grooves 66 of both clamps fit onto the fixing rod 11. Subsequently, use two centrally symmetrical fastening bolts 64 to initially lock the upper and lower clamps. Each fastening bolt 64 is equipped with a flange-face anti-loosening nut to prevent the upper clamp 61 and lower clamp 62 from shifting during the installation of the positioning pin 65. After the upper and lower clamps are fully locked, drive two cylindrical positioning pins 65 into the corresponding pin holes on them to ensure that there is no relative displacement between the clamps and the fixing rod 11.

[0040] In addition, the surfaces of the arc-shaped grooves 66 on the inner walls of the upper clamp 61 and the lower clamp 62 are knurled to further increase the static friction between the clamp and the fixing rod 11.

[0041] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
