Description

Technical Field

[0001] This utility model relates to the technical field of hygiene product manufacturing equipment, specifically to an air intake and delivery structure. Background Technology

[0002] In the production of disposable hygiene products such as baby diapers, pull-ups, and trousers, suction boxes are needed to hold the products in place while they are being conveyed on the main production line. As living standards improve, the required sizes of diapers and pull-ups are increasing, necessitating wider suction boxes. However, when using wider suction boxes, the distance between the suction box and the mounting base is smaller, making installation difficult with a wrench and requiring more manual labor for installation and maintenance. Utility Model Content

[0003] Therefore, in view of the above problems, this utility model provides an air intake and conveying structure to solve the problem of difficult disassembly and assembly operations caused by the narrow installation space between the side of the wide air intake box and the equipment mounting base.

[0006] An air intake box, wherein at least two elongated holes are provided on the left and right sides of the air intake box along the width direction of the air intake box;

[0007] A mounting bracket is used to fix the air intake box to the equipment mounting bracket;

[0008] An adjustment plate, which is movably disposed at each of the elongated holes;

[0009] Fixing bolts are used to fix each of the adjustment plates to the air intake box. Loosening each of the fixing bolts allows each of the adjustment plates to be moved away to expose each of the elongated holes.

[0010] Furthermore, the air intake box includes a shell closed at both ends and mounting blocks at both ends of the shell. Each mounting block includes a solid part located on the side of the shell and a hollow part covering the outside of the shell. The elongated holes are provided on both sides of the shell and on the solid part.

[0011] Furthermore, each hollow part is provided with a positioning post connected to the solid part, and the housing is provided with a positioning groove that matches each positioning post.

[0012] Furthermore, each of the positioning posts has threads on its surface, and each of the positioning grooves has threads corresponding to the surface of the positioning post.

[0013] Furthermore, all of the aforementioned fixing bolts are wing bolts.

[0014] Furthermore, each of the adjustment plates has an adjustment hole arranged along the length of the air intake box, and each of the fixing screws passes through the corresponding adjustment hole and is connected to the air intake box.

[0015] Furthermore, the inner edges of each of the elongated holes are provided with chamfers or rounded corners.

[0016] Furthermore, the adjustment plate is made of stainless steel or aluminum alloy, and the contact surface between the adjustment plate and the air intake box is provided with a sealing gasket or sealing adhesive layer.

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

[0018] This invention provides an operating channel for the tool by creating an elongated hole and designing a movable adjustment plate, making it possible to disassemble and assemble the wide suction box in narrow spaces. Maintenance can be performed simply by loosening the fixing bolts and removing the adjustment plate, without disassembling the entire equipment panel or surrounding complex components. This significantly reduces downtime and labor costs. The entire solution consists of only a few parts, including the suction box, fixed base, adjustment plate, and fixing bolts, resulting in a simple structure, low failure rate, and controllable manufacturing costs. In non-maintenance mode, the adjustment plate effectively covers the elongated hole, ensuring the suction box's airtightness, maintaining sufficient vacuum suction force, and guaranteeing stable production line operation.

[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: Figures 1 to 4 As shown, the suction conveying structure provided in this embodiment mainly includes a suction box 1, a fixed base 2, an adjusting plate 3, and a fixing bolt 4. The fixed base 2 is used to fix the entire suction box 1 to the equipment, and the fixing bolt 4 is a wing bolt.

[0033] The air intake box 1 has four elongated holes 5 extending along its width on each of its left and right sides, located on the upper and lower sides of the air intake box respectively, providing sufficient tool passages for fixing operations inside. The inner edges of the elongated holes 5 are all rounded to avoid stress concentration and protect the installation tools.

[0034] In other preferred embodiments, the interior of the air intake box 1 is provided with longitudinal reinforcing ribs along the length of the air intake box 1 to enhance the overall structural rigidity and prevent deformation caused by negative pressure and its own weight.

[0035] The intake box 1 includes a shell 6 closed at both ends and two mounting blocks 7 respectively disposed at both ends of the shell. The mounting blocks 7 are composed of a solid part 71 and a hollow part 72. The solid part 71 is close to the side wall of the shell 6, and the hollow part 72 covers the outside of the shell 6, which ensures structural strength and reduces the overall weight. Each hollow part 72 is provided with an integrally formed positioning post 73. Correspondingly, a positioning groove 11 that precisely matches the positioning post 73 is provided on the end face of the shell 1. The connection between the shell 6 and the mounting blocks 7 is achieved by bolts 61 and nuts 62. The bolts 61 pass through the solid part of the mounting blocks 7 and extend into the shell 6, while the nuts 62 are disposed in the shell 6. During installation, the bolts 61 and nuts 62 are locked by inserting a hexagonal wrench into the elongated hole 5. To further enhance the connection strength, in this embodiment, the surface of the positioning post 73 is machined with external threads, and the positioning groove 11 is machined with internal threads that match it. Through the thread engagement, the mounting blocks 7 and the shell 6 are firmly connected as a whole.

[0036] The adjustment plate 3 is made of stainless steel, which has good strength and corrosion resistance. To facilitate installation and fine-tuning of position, the adjustment plate 3 is provided with an adjustment hole 31 along the length of the air intake box 1. On the contact surface between the adjustment plate 3 and the housing 6 of the air intake box 1, a rubber sealing gasket 32 ​​is provided to seal the long hole 5 after tightening to prevent air leakage.

[0037] 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.
