A pre-milling and scraping device for an edge banding machine

Abstract

This utility model belongs to the technical field of edge banding machines, and particularly relates to a pre-milling and scraping device for edge banding machines. It includes an edge banding frame, a pre-milling frame fixedly connected to the outer wall of the edge banding frame, a milling roller on the outer wall of the pre-milling frame, and an adjusting screw on the inner wall of the pre-milling frame. An adjusting base is threadedly connected to the outer wall of the adjusting screw. A scraper is installed, and a spring, through its own elasticity, drives a telescopic block to slide. The sliding of the telescopic block causes two sets of connecting rods to move synchronously, allowing the telescopic block to slide vertically along the limiting groove via the connecting rods. The sliding of the scraper causes the scraper at one end of the scraper frame to come into contact with the edge of the board, thereby cleaning the burrs after pre-milling. Then, the operator rotates the adjusting screw, which, through its thread, causes the adjusting base and the telescopic block to slide relative to each other, thereby adjusting the spring force to ensure a tight fit between the scraper and the edge of the board, preventing incomplete burr removal.

Description

Technical Field

[0001] This utility model belongs to the technical field of edge banding machines, and in particular relates to a pre-milling and scraping device for edge banding machines. Background Technology

[0002] When the edge banding machine is used for edge banding, it is necessary to pre-mill the edge of the board. After pre-milling, the edge of the board often has burrs, which need to be removed by the pre-milling scraping device.

[0003] For example, patent CN207431430U discloses an edge-scraping device for an edge-sealing machine, including an edge-scraping knife, a knife holder, a guide wheel, a fixed base, a linear shaft, a connecting buffer assembly, and a positioning plate assembly. The knife holder is characterized by comprising a support plate, a locking bolt, a locking nut, an adjusting screw, and an adjusting nut. The support plate has an adjusting through hole, and an opening on one side of the adjusting through hole divides the support plate into an upper frame plate and a lower frame plate. The lower frame plate has a through hole and a threaded through hole, the center lines of which are perpendicular to the center line of the adjusting through hole. The upper frame plate has a locking threaded through hole corresponding to the through hole, the center line of which coincides with the center line of the through hole. The front end of the locking bolt passes through the through hole and the locking nut and connects to the locking threaded through hole. One end of the adjusting screw passes through the threaded through hole and abuts against the upper frame plate, while the other end is connected to the adjusting nut. This device has advantages such as simple structure, convenient operation, and high adjustment accuracy.

[0004] Existing edge banding machines using pre-milling and scraping devices often fail to achieve a tight fit between the scraper and the edge of the board, resulting in incomplete burr removal. Therefore, we propose a pre-milling and scraping device for edge banding machines. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned technical problems by providing a pre-milling and scraping device for edge banding machines, thus avoiding the problem of incomplete burr removal by scrapers.

[0006] In view of this, the present invention provides a pre-milling and scraping device for an edge banding machine, including an edge banding frame, a pre-milling frame fixedly connected to the outer wall of the edge banding frame, a milling roller provided on the outer wall of the pre-milling frame, an adjusting screw provided on the inner wall of the pre-milling frame, an adjusting base threadedly connected to the outer wall of the adjusting screw, a spring fixedly connected to the outer wall of the adjusting base, a telescopic block fixedly connected to one end of the spring, a connecting rod screwed to both ends of the telescopic block, a scraping seat screwed to one end of the connecting rod, a limit groove provided at the connection between the pre-milling frame and the scraping seat, a scraping frame fixedly connected to the outer wall of the scraping seat, and a scraper fixedly connected to one end of the scraping frame;

[0007] An edge banding assembly, located at the top of the edge banding frame, is used to perform edge banding operations on the board material.

[0008] Based on the above structure, the spring drives the telescopic block to slide through its own elastic force. The sliding of the telescopic block causes the two sets of connecting rods to move synchronously, so that the sliding of the telescopic block drives the scraper seat to slide vertically along the groove of the limiting groove through the connecting rods. The sliding of the scraper seat causes the scraper at one end of the scraper frame to fit against the edge of the board, thereby cleaning the burrs after the board is pre-milled. Then, the operator rotates the adjusting screw, which drives the adjusting base to slide relative to the telescopic block through the thread, thereby adjusting the magnitude of the spring force, so as to achieve a tight fit between the scraper and the edge of the board and avoid incomplete burr removal.

[0009] Preferably, the central axes of the adjusting base and the telescopic block coincide. In this embodiment, the operator rotates the adjusting screw, which drives the adjusting base and the telescopic block to slide relative to each other through the thread, thereby adjusting the magnitude of the spring force and achieving a tight fit between the scraper and the edge of the board.

[0010] Preferably, the scraping seat forms a sliding structure with the limiting groove through the telescopic block and the connecting rod. The limiting groove is vertical. In this embodiment, the telescopic block slides through the connecting rod to drive the scraping seat to slide vertically along the groove of the limiting groove, thereby realizing the control operation of the vertical sliding of the scraping seat.

[0011] Preferably, the outer wall of the scraper is arc-shaped. In this embodiment, the scraper seat slides to drive the scraper at one end of the scraper frame to fit against the edge of the plate, thereby cleaning the burrs after the plate is pre-milled.

[0012] Preferably, the edge-sealing assembly includes:

[0013] The edge banding frame has an active roller at its top and a driven roller that is screwed to the top of the edge banding frame on one side. A gluing roller is located on one side of the milling roller, a first pressure roller is located on one side of the gluing roller, and a second pressure roller is located on one side of the first pressure roller. In this embodiment, the gluing roller applies glue evenly to the edge banding surface of the board. Then, the first and second pressure rollers press the edge banding strip tightly against the edge banding surface of the board, thus achieving the edge banding operation.

[0014] Preferably, the active rollers are equidistantly distributed along the top of the edge sealing frame, and the active rollers and driven rollers correspond one-to-one. In this embodiment, it is convenient for workers to place the board on the active rollers and driven rollers. The active rollers drive the board to be conveyed, avoiding the board from shifting during conveying.

[0015] Preferably, the diameter of the first pressure roller is smaller than the diameter of the second pressure roller. In this embodiment, by setting the relative sizes of the first and second pressure rollers, it is beneficial to perform graded pressing operations on the board and edge banding strip, and to avoid serious glue overflow from the board and edge banding strip.

[0016] The beneficial effects of this utility model are:

[0017] 1. This edge banding machine uses a pre-milling and scraping device. By setting a scraper, the spring drives the telescopic block to slide through its own elasticity. The sliding of the telescopic block drives two sets of connecting rods to move synchronously. This causes the telescopic block to slide vertically along the limiting groove through the connecting rods. The sliding of the scraping seat causes the scraper at one end of the scraping frame to come into contact with the edge of the board, thereby cleaning the burrs after pre-milling. Then, the operator rotates the adjusting screw. The adjusting screw drives the adjusting base to slide relative to the telescopic block through the thread, thereby adjusting the spring force to achieve a tight fit between the scraper and the edge of the board, avoiding incomplete burr removal.

[0018] 2. This edge banding machine uses a pre-milling and scraping device. By setting a first pressure roller and a second pressure roller, the glue application roller works to evenly apply glue to the edge banding surface of the board. Then, the first pressure roller and the second pressure roller tightly press the edge banding strip to the edge banding surface of the board to achieve the edge banding operation. The diameter of the first pressure roller is smaller than the diameter of the second pressure roller, which is conducive to the graded pressing operation of the board and the edge banding strip and avoids serious glue overflow on the board and the edge banding strip.

[0028] Edge banding assembly, located at the top of edge banding frame 1, is used to perform edge banding operations on the board.

[0029] Based on the above structure, the spring 6 drives the telescopic block 7 to slide through its own elastic force. The sliding of the telescopic block 7 drives the two sets of connecting rods 8 to move synchronously. This causes the telescopic block 7 to slide vertically along the groove of the limiting groove 10 through the connecting rods 8. The sliding of the edge scraping seat 9 causes the scraper 12 at one end of the edge scraping frame 11 to fit against the edge of the board, thereby cleaning the burrs after the board is pre-milled. Then, the operator rotates the adjusting screw 4. The adjusting screw 4 drives the adjusting base 5 to slide relative to the telescopic block 7 through the thread, thereby adjusting the elastic force of the spring 6 to achieve a tight fit between the scraper 12 and the edge of the board, avoiding incomplete burr removal.

[0030] In one embodiment, the central axes of the adjusting base 5 and the telescopic block 7 coincide.

[0031] In this embodiment, the operator rotates the adjusting screw 4, which drives the adjusting base 5 and the telescopic block 7 to slide relative to each other through the thread, thereby adjusting the elastic force of the spring 6 to achieve a tight fit between the scraper 12 and the edge of the board.

[0032] In one embodiment, the scraping seat 9 forms a sliding structure with the limiting groove 10 through the telescopic block 7 and the connecting rod 8, and the limiting groove 10 is vertical.

[0033] In this embodiment, the telescopic block 7 slides through the connecting rod 8 to drive the scraping seat 9 to slide vertically along the groove of the limiting groove 10, thereby realizing the control operation of the vertical sliding of the scraping seat 9.

[0034] In one embodiment, the outer wall of the scraper 12 is arc-shaped.

[0035] In this embodiment, the scraper seat 9 slides to drive the scraper 12 at one end of the scraper frame 11 to fit against the edge of the board, thereby cleaning the burrs after the board is pre-milled.

[0036] In one embodiment, the edge-sealing component includes:

[0037] The active roller 13 is provided at the top of the sealing frame 1. A driven roller 14 is provided on one side of the active roller 13 and screwed to the top of the sealing frame 1. A glue-applying roller 15 is provided on one side of the milling roller 3. A first pressure roller 16 is provided on one side of the glue-applying roller 15. A second pressure roller 17 is provided on one side of the first pressure roller 16.

[0038] In this embodiment, the glue-applying roller 15 applies glue evenly to the edge-sealing surface of the board. Then, the first pressure roller 16 and the second pressure roller 17 press the edge-sealing strip tightly against the edge-sealing surface of the board to achieve the edge-sealing operation of the board.

[0039] In one embodiment, the active rollers 13 are equidistantly distributed along the top of the edge sealing frame 1, and the active rollers 13 and the driven rollers 14 correspond one-to-one.

[0040] In this embodiment, it is convenient for workers to place the board on the active roller 13 and the driven roller 14. The active roller 13 drives the board to be conveyed, avoiding the board from shifting during conveying.

[0041] In one embodiment, the diameter of the first pressure roller 16 is smaller than the diameter of the second pressure roller 17.

[0043] In this embodiment, when using the pre-milling and scraping device for the edge banding machine, the operator first places the board on the drive roller 13 and the driven roller 14. The drive roller 13 drives the board to be conveyed. Then, the motor drives the milling roller 3 to rotate and pre-mill the edge banding surface of the board.

[0044] Then, the spring 6 drives the telescopic block 7 to slide through its own elastic force. The sliding of the telescopic block 7 drives the two sets of connecting rods 8 to move synchronously. This causes the telescopic block 7 to slide vertically along the groove of the limiting groove 10 through the connecting rods 8. The sliding of the edge scraping seat 9 causes the scraper 12 at one end of the edge scraping frame 11 to fit against the edge of the board, thereby cleaning the burrs after the board is pre-milled. Then, the operator rotates the adjusting screw 4. The adjusting screw 4 drives the adjusting base 5 to slide relative to the telescopic block 7 through the thread, thereby adjusting the elastic force of the spring 6 to achieve a tight fit between the scraper 12 and the edge of the board, avoiding incomplete burr removal.

[0045] Finally, the glue-applying roller 15 applies glue evenly to the edge-sealing surface of the board. Then, the first pressure roller 16 and the second pressure roller 17 press the edge-sealing strip tightly against the edge-sealing surface of the board to achieve the edge-sealing operation of the board.
