Description

Technical Field

[0001] The utility model relates to the technical field of metal strip processing, in particular to a heating roller pressing mechanism with pressure detection. Background Art

[0002] In the process of compounding thinner metal strips with different materials, such as copper foil, due to the hard texture of copper, a higher processing temperature is required according to the process requirements to make the copper better compounded with other materials and make it firmly bonded. At the same time, a larger diameter heating roller is also required to process the copper foil. The large diameter heating roller can not only provide a larger heating area, but also make the copper foil more evenly pressurized, thereby ensuring uniform processing of the copper foil. This makes the heating roller for processing copper foil higher in temperature and larger in diameter, but the existing heating roller press mechanism does not have the function of heat insulation. Temperature changes will cause the sensitivity of the pressure sensor to change, thereby affecting the accuracy of the measurement results and making it impossible to accurately detect the pressure exerted on the copper foil during processing. High temperature also makes it impossible for workers to repair the heating roller press mechanism in use, and the cylinder in the existing heating roller press mechanism is used for heating rollers with smaller diameters and is not suitable for heating rollers with large diameters.

[0003] Therefore, a heating roller pressing and lifting mechanism with pressure detection is needed to solve the above problems. Utility Model Content

[0004] The utility model proposes a heating roller pressing and lifting mechanism with pressure detection, which performs heat insulation treatment on the pressure sensor, reducing the influence of high temperature on the heating roller on the sensitivity of the pressure sensor, so that the pressure exerted on the metal strip during processing can be accurately detected. The cylinder piston rod and the lifting plate are connected by a connecting seat, which realizes the downward pressing and lifting of the upper large-diameter heating roller without affecting the pressure detection.

[0005] The technical solution of the present utility model is achieved as follows:

[0006] A heating roller pressing and lifting mechanism with pressure detection includes a knife seat on which an upper large-diameter heating roller and a lower large-diameter heating roller are rotatably mounted, and the upper large-diameter heating roller is connected to a pressing and lifting assembly;

[0007] The pressure-lifting assembly includes a cylinder mounting seat mounted on the tool holder, two cylinders are fixedly mounted on the cylinder mounting seat, piston rods of the two cylinders pass through the cylinder mounting seat and are provided with a connecting plate, the pressure-lifting assembly also includes a lifting plate driven by the two cylinders, the lifting plate is connected to the upper large-diameter heating roller, two first heat insulation plates are fixedly mounted on the lifting plate, each of the first heat insulation plates is fixedly mounted with a connecting seat, each of the connecting seats is provided with a through hole for adapting to the corresponding cylinder piston rod, each of the through holes is provided with a limiting end surface for limiting the corresponding connecting plate, and a pressure sensor is provided between each connecting plate and the corresponding first heat insulation plate.

[0008] As a preferred technical solution, both ends of the upper large-diameter heating roller are connected to a bearing box, each of the bearing boxes is constrained and installed on the knife seat, and a second insulation block is fixedly installed between the lifting plate and the two bearing boxes.

[0009] As a preferred technical solution, a third heat insulation block is fixedly installed between the cylinder mounting seat and the tool holder.

[0010] As a preferred technical solution, a connection plate limiting cavity is formed between the corresponding limiting end surface and the corresponding bottom of the connection seat in each through hole.

[0011] As a preferred technical solution, the cylinder mounting seat, the lifting plate, the upper large-diameter heating roller and the lower large-diameter heating roller are all arranged horizontally, and the two cylinders are both arranged vertically.

[0012] By adopting the above technical solution, the beneficial effects of the utility model are:

[0013] Since the heating roller pressing and lifting mechanism with pressure detection includes a pressing and lifting assembly, during the process of processing the metal strip, the metal strip is placed between the upper large-diameter heating roller and the lower large-diameter heating roller, the piston rod of the cylinder extends, and the piston rod pushes the lifting plate down, and the upper large-diameter heating roller and the lower large-diameter heating roller apply pressure to the metal strip, and this mechanism is started, the upper large-diameter heating roller and the lower large-diameter heating roller are heated. After being heated to a certain temperature, the upper large-diameter heating roller and the lower large-diameter heating roller process the metal strip under the traction of the traction device. In the present utility model, the heat that affects the sensitivity of the pressure sensor is mainly transferred to the pressure sensor through the lifting plate by the upper large-diameter heating roller. By arranging a first thermal insulation block between the lifting plate and the pressure sensor, the influence of the high temperature on the upper large-diameter heating roller on the sensitivity of the pressure sensor is reduced, so that the pressure exerted on the metal strip during the processing can be accurately detected.

[0014] In the present invention, through the cooperation between the connecting disk and the connecting seat, when the cylinder piston rod descends, the connecting disk presses against the pressure sensor in the vertical direction in the connecting disk limit cavity, and pushes the lifting plate down, thereby realizing the downward pressure of the upper large-diameter heating roller. When the cylinder piston rod rises, the top of the connecting disk presses against the limit end face, and the connecting disk drives the lifting seat to move upward, that is, drives the lifting plate to move upward, thereby realizing the lifting of the upper large straight-down heating roller. At this time, there is no pressure between the connecting disk and the pressure sensor, so through the cooperation between the connecting disk and the connecting seat, the downward pressure and lifting of the upper large-diameter heating roller are realized without affecting the pressure detection.

[0015] Since the heating roller lifting mechanism with pressure detection includes a second heat insulation plate, the setting of the second heat insulation plate can reduce the conduction of heat from the upper large-diameter heating roller to the lifting plate, thereby further avoiding the influence of the heat from the upper large direct-fall heating roller on the sensitivity of the pressure sensor.

[0016] Since the heating roller lifting mechanism with pressure detection includes a third heat insulation plate, during the use of this device, the heat on the two heating rollers will be transferred to the tool holder through the bearing box, and the heat on the tool holder will be transferred to the pressure sensor through the cylinder mounting seat and the cylinder. The provision of the third heat insulation plate can reduce the impact of the heat on the tool holder on the pressure sensor. At the same time, it reduces the temperature on the cylinder mounting seat, making it convenient for workers to perform maintenance on this mechanism while it is in use. In addition, the piston, piston rod, valve and other components of the cylinder will expand due to high temperature, resulting in a smaller fitting clearance, thereby affecting the normal operation of the cylinder. The provision of the third heat insulation block can also reduce the impact of the heat on the two heating rollers on the cylinder. BRIEF DESCRIPTION OF THE DRAWINGS
