Description

Technical Field

[0001] This utility model belongs to the field of polishing equipment technology, and specifically relates to a belt polishing mechanism that can correct deviation and tension. Background Technology

[0002] A belt polishing mechanism is a type of polishing mechanism in grinding and polishing machines. It is a commonly used machining mechanism capable of grinding and polishing the surface of sheet metal, and is widely used in industries that require processing sheet metal or other sheet materials. The belt grinding and polishing mechanism mainly works by bringing the sheet metal surface into contact with an abrasive belt, utilizing the grinding properties of the abrasive grains on the belt to grind and polish the workpiece surface. Sheet metal surfaces polished using belt grinding and polishing exhibit high quality and precision.

[0003] However, existing belt polishing mechanisms typically adjust the belt tension using a fixed tensioning wheel, which cannot be adaptively adjusted and cannot achieve automatic belt correction. Utility Model Content

[0004] The purpose of this invention is to provide a belt polishing mechanism that can correct deviation and tension. This invention achieves adaptive tensioning and automatic deviation correction of the polishing belt by designing a correction roller, a correction cylinder, and a tensioning cylinder.

[0005] To solve the above-mentioned technical problems, this utility model provides a belt polishing mechanism that can correct deviation and tension, comprising:

[0006] The polishing roller has its shaft end rotatably mounted on the crossbeam of the frame via a bearing seat;

[0007] The correction roller has its shaft end rotatably mounted on the floating beam via a bearing seat. A tension cylinder and a correction cylinder are mounted on the beam. The drive end of the tension cylinder is rotatably connected to the bottom center end of the floating beam. The two drive ends of the correction cylinder abut against a U-shaped correction frame, which is mounted on one end of the floating beam.

[0008] Polishing abrasive belt is wound around the polishing roller and the straightening roller.

[0009] Preferably, the shaft end of either side of the polishing roller is connected to a drive mechanism mounted on the frame to realize the rotation of the polishing roller.

[0010] Preferably, the surface of the polishing roller further includes spiral grooves, and the spiral grooves are formed along the axial surface path of the polishing roller.

[0011] Preferably, it also includes a tension sensor, which is installed between the bearing housing and the floating beam to detect the tension of the polishing belt.

[0012] Preferably, the two drive ends of the correction cylinder move forward or backward synchronously, and the two drive ends are further provided with springs, the two ends of which are respectively connected to the cylinder body of the correction cylinder and the abutment block of the drive end.

[0013] Preferably, it also includes a screw fine-tuning mechanism, which is arranged on the crossbeam, and the front and rear positions of the correction cylinder can be finely adjusted by adjusting the screw fine-tuning mechanism.

[0014] Preferably, it also includes an external correction sensor, which is mounted on a frame on one side of the edge of the polishing belt.

[0015] Preferably, the correction sensor is a high-speed linear array CCD sensor.

[0016] Preferably, the crossbeam of the frame is mounted on a lifting mechanism to achieve vertical adjustment of the polishing roller.

[0017] Compared with the prior art, this utility model has the following advantages:

[0018] This invention allows for adaptive adjustment of the tension of the polishing belt by extending the drive end of the tensioning cylinder upwards or shortening downwards when the tension of the polishing belt is too high or too low. This drives the alignment roller to adjust its displacement up and down, thus achieving the function of adaptive adjustment of the tension of the wound polishing belt. The alignment cylinder's drive end moves forward and backward; when the front drive end moves forward, the rear drive end moves forward simultaneously. At this time, the front drive end applies a resisting force to the U-shaped alignment frame, causing the left end of the alignment roller to deflect forward at a certain angle around the bearing between the tensioning cylinder and the floating beam, thus correcting the polishing belt when it shifts to the right.

Detailed Implementation

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0026] like Figures 1-5 As shown, this utility model embodiment provides a belt polishing mechanism that can correct deviation and tension, including:

[0027] The polishing roller 1 has its two shaft ends rotatably mounted on the crossbeam 3 of the frame via bearing seats 2;

[0028] The correction roller 4 has its two shaft ends rotatably mounted on the floating beam 6 via bearing seats 2 5. The crossbeam 3 is equipped with a tension cylinder 7 and a correction cylinder 8. The tension cylinder 7 is located at the top center of the crossbeam 3. The drive end of the tension cylinder 7 is rotatably connected to the bottom center end of the floating beam 6 via a bearing. The two drive ends of the correction cylinder 8 abut against the front and rear side walls of the U-shaped correction frame 9. The U-shaped correction frame 9 is installed at one end of the floating beam 6.

[0029] The polishing belt 10 is wound around the polishing roller 1 and the straightening roller 4. Through the drive of the polishing roller 1 and the straightening roller 4, the polishing belt 10 rotates to polish and grind the surface of the material to be processed. When the tension of the polishing belt 10 is too high or too low, the drive end of the tensioning cylinder 7 extends upward or shortens downward to drive the straightening roller 4 to adjust its displacement up and down, thereby realizing the function of adaptive adjustment of the tension of the wound polishing belt 10. The correction cylinder 8 moves forward and backward. When the front drive end moves forward, the rear drive end moves forward synchronously. At this time, the front drive end applies a resisting force to the U-shaped correction frame 9, causing the left end of the correction roller 4 to deflect forward at a certain angle with the bearing between the tension cylinder 7 and the floating beam 6 as the rotation center. This creates a "taper" on the right side of the roller surface. When the polishing belt 10 passes through this "twisted" roller, it will be subjected to a lateral force to the left, which will push the polishing belt 10 back to the center position to correct the deviation of the polishing belt 10 to the right.

[0030] The shaft end of the polishing roller 1 on either side is connected to the drive mechanism mounted on the frame. The drive mechanism provides power and transmits the power to the polishing roller 1 to achieve the rotation of the polishing roller 1.

[0031] The surface of the polishing roller 1 also includes spiral grooves 11, which are opened along the axial surface path of the polishing roller 1. By opening the spiral grooves 11, when they are wrapped with the polishing belt 10, the polishing and grinding ability of the polishing belt 10 on the surface of the board is enhanced.

[0032] It also includes a tension sensor 71, which is installed between the bearing housing 2 5 and the floating beam 6 to detect the tension of the polishing belt 10. By dynamically acquiring and detecting the tension of the polishing belt 10 wrapped around the straightening roller 4 through the tension sensor 71, the tension data can be sent to an external PLC controller. The controller's feedback signal controls the tension cylinder 7 to move up or down, thereby adjusting the vertical position of the polishing roller 1 and achieving the purpose of adaptive tension adjustment.

[0033] The two drive ends of the correction cylinder 8 move forward or backward synchronously, and each drive end is also equipped with a spring 81. The two ends of the spring 81 are connected to the cylinder body of the correction cylinder 8 and the abutment block 82 of the drive end, respectively. The spring 81 provided above makes the force applied by the correction cylinder 8 to the floating beam 6 more stable.

[0034] It also includes a screw fine-tuning mechanism 83, which is arranged on the crossbeam 3. By adjusting the screw fine-tuning mechanism 83, the front and rear positions of the correction cylinder 8 can be finely adjusted. This allows for fine-tuning and centering of the position of the correction cylinder 8 during assembly or subsequent maintenance.

[0035] It also includes an external correction sensor, which is installed on the frame on one side of the edge of the polishing belt 10. It is used to detect the deviation displacement of the polishing belt 10 in real time and control the correction cylinder 8 to perform correction action.

[0036] The correction sensor is a high-speed linear array CCD sensor, which achieves the advantages of high-precision detection and fast response.

[0037] The crossbeam 3 of the frame is installed on the lifting mechanism to adjust the polishing roller 1 and the entire structure installed on it up and down, so as to adjust the contact distance between the surface of the plate and the polishing belt 10, and facilitate the polishing and grinding.

[0038] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
