Description

Technical Field

[0001] This utility model relates to the field of machinery, and in particular to a feeding rack for a composite board production line. Background Technology

[0002] Composite panels are a common type of building material, consisting of two layers of metal sheets and a filler core. They are widely used in petrochemical, pharmaceutical, and light industrial fields. In composite panel production lines, metal sheet coils are conveyed via a rotating shaft. The production line folds the edges of the upper and lower metal sheets to form 90° side panels. The filler core is then filled between the two layers, followed by adhesive application, curing, and extrusion to form the composite panel. The composite panel production line feeds the metal sheets using metal coils, thus requiring a coil unloading rack. Existing unloading racks typically require threading the metal coil onto a tensioning shaft, which is then fixed at both ends. Changing the coil usually requires multiple people to loosen one end of the tensioning shaft, replace the coil, and then reinstall it; this is not only inefficient but also often results in the motor driving the tensioning shaft being located on one side or vertically, leading to a large guide column structure and impacting the overall structural design of the production line. Utility Model Content

[0003] The purpose of this utility model is to provide a material feeding rack for a composite board production line that solves or partially solves the above-mentioned technical problems.

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

[0005] A feeding rack for a composite board production line includes a base, on which two mounting seats are movably disposed. Each mounting seat has a rod-shaped cantilever extending horizontally in a first direction. The free end of each cantilever is provided with a tensioning mechanism.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] In the description of this utility model, it should be noted that the terms "inner", "outer", "upper", "lower", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do 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. Therefore, they should not be construed as limitations on this utility model.

[0023] like Figures 1 to 6 As shown, a feeding rack for a composite board production line according to this utility model includes a base 10. Two mounting seats 12 are movably mounted on the base 10. Each mounting seat 12 has a rod-shaped cantilever 14 extending horizontally (or inclined) in a first direction. A tensioning mechanism 16 is mounted at the free end of each cantilever 14. The tensioning mechanism 16 includes a tensioning base 52 rotatably mounted on the cantilever 14. A rotary motor 20 is mounted on the mounting seat 12 to drive the tensioning base 52 to rotate. The mounting seat 12 is movable, allowing the tensioning mechanism 16 to clamp or release the roll material. The rotary motor 20 drives the tensioning base 52 to rotate, achieving active feeding. The cantilever 14 extends the tensioning mechanism 16 outwards, and the rotary motor 20's mounting on the mounting seat 12 ensures a compact overall structure. The tensioning mechanism 16 is a structure that tensions the center hole of the roll material from the inside out, and it is widely used in roll material feeding structures.

[0024] Specifically, the base 10 has two first slide rails 18 arranged along the second direction, with the first and second directions perpendicular to each other. The mounting base 12 is movably mounted on the first slide rails 18. The cross-section of the first slide rail 18 is a dovetail groove structure to achieve stable movement.

[0025] Two double-threaded screws 22 are rotatably mounted on the base 10 along a second direction. Each end of a double-threaded screw 22 has an external thread with a different rotation direction. Two mounting seats 12 are threadedly connected to the external threads at one end of each double-threaded screw 22. A drive motor 24 is mounted on the base 10 to drive one double-threaded screw 22 to rotate. Specifically, four bearings 26 are mounted on the base 10, and each double-threaded screw 22 passes through two bearings 26. A sprocket 28 is located on the middle portion of one double-threaded screw 22 between the two bearings 26. The drive motor 24 is also fixedly mounted on the base 10. A sprocket 30 is mounted on the output shaft of the drive motor 24. The sprockets 28 and 30 are connected by a chain 50, thereby driving the double-threaded screw 22 to rotate. A synchronous belt (not shown) is fitted onto both ends of the two double-threaded screws 22 to drive them to rotate synchronously. This structure enables the drive motor 24 to drive two double-threaded screws 22 to rotate synchronously via a chain. The threads at both ends of the screws 22 then drive the mounting seats 12 to move relative to or towards each other, thus clamping or releasing the roll material. Based on this principle, those skilled in the art can easily derive the following structure: one mounting seat 12 is fixed, and only one double-threaded screw 22 is needed to drive the other mounting seat 12 to move, achieving the same clamping or releasing of the roll material. This derived structure should be considered an equivalent technical solution of this utility model.

[0026] The cantilever 14 is a square steel bar with a U-shaped cross-section. A transmission chain 32 connecting the tensioning base 52 and the rotary motor 20 is installed inside the cantilever 14. A sprocket (not shown) connected to the transmission chain 32 and located inside the cantilever 14 is mounted on the output shaft of the tensioning base 52 and the rotary motor 20. This structure helps protect the transmission chain 32, preventing the moving parts from being exposed, thereby improving safety.

[0027] The tensioning mechanism 16 of this utility model adopts the following structure: four support plates 34 are movably arranged on the tensioning base 52, and a telescopic rod 36 is movably arranged on the tensioning base 52 along its rotation axis. The telescopic rod 36 is movably connected to all the support plates 34 through a connecting rod 37. The tensioning base 52 is also provided with a drive mechanism for driving the telescopic rod 36 to move along the rotation axis of the tensioning base 52.

[0028] The tensioning mechanism 16 of this utility model can also take other forms, such as the applicant's previous cases 2011102518702 and 2022101846553.

[0029] In this embodiment, the telescopic rod 36 is a lead screw, and the driving mechanism includes a threaded sleeve 38 threadedly connected to the telescopic rod 36 and a tensioning motor 40 that drives the threaded sleeve 38 to rotate. The threaded sleeve 38 is movably mounted on the mounting plate. The tensioning motor 40 drives the threaded sleeve 38 to rotate, thereby driving the telescopic rod 36 to move back and forth. Of course, the driving mechanism can also be replaced with a pneumatic cylinder, hydraulic cylinder, or electric cylinder, which can achieve the same function.

[0030] The tensioning base 52 is provided with four sliding grooves 42, and the support plates 34 are all movably disposed in one of the sliding grooves 42.

[0031] The working principle of the above structure is as follows: the tensioning motor 40 drives the telescopic rod 36 to move, and the telescopic rod 36 drives the support plate 34 to move along the slide groove 42 through the connecting rod. When it moves outward, it can tighten the roll material from the inside out; otherwise, it will loosen the roll material.

[0032] The tensioning motor 40 can be installed on the cantilever 14. When the tensioning base 52 rotates, the tensioning motor 40 continuously provides power to drive the telescopic rod 36 to form a support.

[0033] Furthermore, it also includes a base 44, on which a second slide rail 46 is provided along a second direction, and the base 10 is movably mounted on the second slide rail 46; the base 44 is also provided with an electric cylinder 48 that drives the base 10 to move along the second slide rail 46. It can adjust the overall position when loading the roll material, thereby matching the position of the roll material more quickly and improving efficiency.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
