Description

Technical Field

[0001] This utility model relates to a sander grinding structure. Background Technology

[0002] The full name of the strip shape measuring roller is the strip shape measuring roller. It is a core measuring device used for the shape detection of cold-rolled strip. Its structure is as follows: it includes a steel inner roller, four axial grooves are evenly distributed on the outer circumference of the steel inner roller, and electromagnetic sensors are installed in the axial grooves. Several steel sleeves are sleeved on the outer circumference of the steel inner roller along the axial direction. The tension force of the conveyed strip on the steel sleeves is detected by the electromagnetic sensors to realize the detection of the strip shape.

[0003] As the steel sleeve of the strip shape measuring roller continuously detects the strip shape, its surface will wear under the action of the strip. Since the strip surface is not absolutely flat, the strip shape measuring roller will develop surface quality defects after a period of use, which will affect rolling efficiency and product quality. In order to stabilize product quality, the strip shape roller needs to be replaced in time. If the replaced strip shape roller is discarded directly, it will result in huge waste.

Detailed Implementation

[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0019] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0020] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0021] like Figure 1-4As shown, a belt sander grinding structure includes a base plate 1, on which a belt sanding mechanism 2 is mounted. A grinding fluid pipe 3 is mounted above the front side of the base plate. The belt sanding mechanism includes a support frame 4, on which a belt abutment roller assembly 5 is rotatably connected. A belt tension roller 6 is vertically connected to the middle of the support frame. A belt drive roller 8 driven by a motor 7 is mounted on the rear side of the support frame. A sanding belt 9 is sleeved around the belt abutment roller assembly, the belt tension roller, and the belt drive roller. In use, a plate-shaped roller 32 is mounted on a grinding machine, or the end of the plate-shaped roller can be mounted on a bearing on the grinding machine. This device grinds existing seamless plate-shaped rollers, which are a type of air shaft. Since the plate-shaped roller is mounted on a grinding machine, the air outlet of the plate-shaped roller needs to be blocked while the air inlet of the plate-shaped roller is continuously ventilated. This allows the gaps between the various steel sleeves on the plate-shaped roller and the gaps between the steel sleeves at both ends and the inner steel roller to be filled with gas and exhausted outwards, preventing grinding waste from entering the plate-shaped roller. Then, the belt sander grinding structure of this embodiment is mounted on the grinding machine tool holder on the side of the grinding machine, that is, the base plate is screwed onto the grinding machine tool holder. The movement of the grinding machine tool holder on the horizontal plane drives the sanding belt of the belt sander grinding structure to contact the outer periphery of the plate-shaped roller and the movement of the belt sander grinding structure in the axial direction of the plate-shaped roller. Then, the belt sander drive roller driven by the motor drives the movement of the sanding belt, thereby realizing the sanding of the outer periphery of the plate-shaped roller by the sanding belt.

[0022] In this embodiment, to achieve the overall erection of the belt sander grinding structure, the support frame includes at least one support column 10. This embodiment uses two support columns, which are fixed to the base plate. A support block 11 is provided on the support column, and a rectangular sliding channel 12 with a horizontal front-to-back orientation is provided inside the support block. A rectangular sliding rod 13 is slidably connected in the rectangular sliding channel, with the front end of the rectangular sliding rod extending out of the rectangular sliding channel. The sanding belt abutment roller assembly is installed on the front end of the rectangular sliding rod. Bolts for fixing the rectangular sliding rod are horizontally placed on the side of the support block. The extension and retraction of the rectangular sliding rod drives the extension and retraction of the front sanding belt abutment roller assembly, thereby adjusting the position of the sanding belt abutment roller assembly.

[0023] In this embodiment, to achieve contact between the sanding belt and the plate roller, the sanding belt contact roller assembly includes a vertically arranged contact support plate 14. The middle part of the contact support plate is installed on the front side of the rectangular sliding rod. The upper and lower ends of the contact support plate are symmetrically arranged with forward-facing extension plates 15. The sanding belt contact rollers 16 are rotatably connected to the extension plates. That is, the sanding belt contact roller assembly includes two sanding belt contact rollers, one upper and one lower. The sanding belt is sleeved on the outside of the roller assembly composed of the two sanding belt contact rollers, the sanding belt tensioning roller, and the sanding belt driving roller. In use, the sanding belt sleeved between the two sanding belt contact rollers is used to abut against the plate roller. Specifically, by moving the base plate, the tensioned sanding belt sleeved between the two sanding belt contact rollers abuts against the outer wall surface of the plate roller. At this time, the sanding belt adheres to the outer wall of the plate roller, which facilitates subsequent grinding.

[0024] In this embodiment, in order to make the angle of the sanding belt segment sleeved between the two sanding belt abutting rollers adjustable, the abutting support plate is rotatably connected to the front end of the rectangular sliding rod via the rotating shaft 17. The abutting support plate has an arc-shaped guide groove 18 starting from the circumference of the rotating shaft. The front end of the rectangular sliding rod is provided with a guide screw 19 corresponding to the arc-shaped guide groove. By loosening the guide screw, the abutting support plate can be rotated at a certain angle, and the angle of the sanding belt segment sleeved between the two sanding belt abutting rollers can be adjusted as needed.

[0025] In this embodiment, in order to tension the sanding belt as needed, a swing seat 20 is installed on the support block, a swing rod 21 is hinged to the swing seat, and a telescopic rod 22 is also hinged to the support block. The telescopic end of the telescopic rod is hinged to the swing rod. The telescopic rod can be an existing telescopic pneumatic rod, an electric push rod, or other existing telescopic mechanism. The sanding belt tensioning roller is rotatably connected to the swing rod, and the movement of the swing rod is supported by the telescopic rod.

[0026] In this embodiment, a hinge seat 23 is provided on the side of the swing rod, and a hinge plate 24 is hinged to the hinge seat. The middle part of the hinge plate is hinged to the hinge seat. The plate body on the side of the hinge plate near the hinge seat is divided into two sub-plate bodies by the hinge seat. One sub-plate body is connected to the side of the swing rod by a spring 25. A top bolt 26 is screwed onto the swing rod corresponding to the sub-plate body without a spring. The sanding belt tension roller is rotatably connected to the plate body on the side of the hinge plate away from the hinge seat. The sanding belt tension roller is connected to the hinge plate. The swing angle of the sanding belt tension roller can be adjusted by the top bolt to achieve the purpose of adjusting the sanding belt alignment. This solves the problem that if the sanding belt tension roller is directly rotatably connected to the swing rod, the angle of the tension roller cannot be adjusted, and the sanding belt is prone to deviating and falling off during operation.

[0027] In this embodiment, a handrail 27 is horizontally placed on the upper end of the swing rod to facilitate lifting.

[0028] In this embodiment, to facilitate the cooling of the grinding fluid during grinding, a connecting plate 28 is installed on the front side of the base plate, and an L-shaped mounting bracket 29 is provided on the side wall of the connecting plate. The L-shaped mounting bracket includes a horizontal part and an inclined part. The end of the inclined part is installed on the connecting plate and located next to the belt grinding mechanism. The horizontal part of the L-shaped mounting bracket is located above the front side of the belt abutment roller assembly. The grinding fluid pipeline is installed on the horizontal part of the L-shaped mounting bracket. More specifically, the grinding fluid pipeline includes a nozzle 30 with the nozzle facing downward. The nozzle is fixed to the horizontal part of the L-shaped mounting bracket, and the nozzle input end is connected to an external grinding fluid tank via a hose 31. During grinding, the nozzle pours the external grinding fluid onto the plate roller.
