Description

Technical Field

[0001] This invention relates to the field of material transfer equipment technology, specifically to a hole opener material receiving and unloading mechanism. Background Technology

[0002] A hole saw, also known as a hole saw or hole cutter, is a special type of circular saw used for processing round holes. When mounted on a regular electric drill, it can easily cut round, square, triangular, straight, and curved holes on any surface, including flat surfaces and spherical surfaces, of various materials such as copper, iron, stainless steel, and plexiglass. It is simple and flexible to operate, easy to carry, safe, and has a wide range of applications.

[0003] The main components of a hole saw include: support shank, spring, and drill bit. The support shank is a general-purpose component; hole saws of different diameters typically come with two different sizes of support shank. During the production of hole saws, support shanks, springs, drill bits, and other components need to be processed individually. To improve production efficiency, each component is processed simultaneously at multiple workstations. After processing, the components need to be collected and dumped into a collection box before further processing or assembly. Currently, the collection and dumping of hole saws and their components usually requires manual labor, which is labor-intensive and inefficient. Some collection and dumping equipment can automatically complete the collection and dumping process, but such equipment has a complex structure, requires multiple drive sources to operate, and is cumbersome to control.

[0004] Therefore, designing a simple mechanism that can automatically complete the collection and unloading process of hole punchers and their accessories using only one drive source is a problem that hole punch manufacturers urgently need to solve at this stage. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention provides a hole opener material collection and unloading mechanism.

Detailed Implementation

[0033] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0034] Please refer to Figures 1-6 An embodiment of the hole opener receiving and unloading mechanism provided by the present invention includes:

[0035] The frame 1 is equipped with a support assembly and a limiting roller 11. The support assembly supports the support platform 3 and can drive the support platform 3 to rise, tilt, or fall back to the upright position to complete the tilting action. The support assembly has a drive protrusion 21. The annular conveyor chain 4 drives the push-pull hook 5 in the guide cylinder 42 to move. The push-pull hook 5 can drive the drive protrusion 21 to move, providing external power for the deformation of the support assembly.

[0036] Support platform 3 is mounted on support assembly and moves with support assembly; support platform 3 has limiting groove 31, and limiting protrusion 71 of tilting box 7 matches limiting groove 31. When support platform 3 rises and tilts, limiting protrusion 71 is locked in limiting groove 31, so that tilting box 7 can stably follow support platform 3 to rise and tilt under the limiting of limiting groove 31 and gravity.

[0037] A ring conveyor chain 4 is connected to a drive assembly 41 that drives its rotation. The ring conveyor chain 4 is provided with a vertically arranged guide cylinder 42. A push-pull hook 5 is provided inside the guide cylinder 42. The lower end of the push-pull hook 5 extends out of the guide cylinder 42 and is in the shape of an inverted trapezoid. When the limiting roller 11 contacts the inclined surface of the lower end of the push-pull hook 5, it can smoothly drive the push-pull hook 5 to rise or fall. The upper end of the push-pull hook 5 extends out of the guide cylinder 42 and is provided with a downward-opening push-pull groove 51. The push-pull groove 51 matches the drive protrusion 21. When the push-pull hook 5 rises or falls, the drive protrusion 21 can be disengaged from or locked in the push-pull groove 51.

[0038] The roller conveyor belt 6 has rollers connected to drive sprockets 61, which mesh with the annular conveyor chain 4. When the annular conveyor chain 4 moves, it drives the drive sprockets 61 to rotate, causing the rollers to rotate, which in turn drives the tilting box 7 to move on the roller conveyor belt 6.

[0039] The tilting box 7 is located on the roller conveyor belt 6 and has a limiting protrusion 71. Specifically, the limiting protrusion 71 is preferably located at the bottom middle position of the tilting box 7. When the limiting protrusion 71 is stuck in the limiting groove 31, the tilting box 7 can more stably follow the support platform 3 to rise, fall and tilt.

[0040] Collection box 8 is located on one side of the frame 1. Collection box 8 is used to collect the hole opener or hole opener accessories poured out of the dumping box 7.

[0041] The annular conveyor chain 4 can move between a first position, a second position, and a third position. In the first position, the drive protrusion 21 is engaged in the push-pull groove 51, the support platform 3 is lifted by the support assembly, the limiting protrusion 71 is engaged in the limiting groove 31, the tilting box 7 is located directly above the collection box 8, and the angle between the platform surface of the support platform 3 and the conveying surface of the roller conveyor belt 6 exceeds 90°. The opening device or opening device accessory in the tilting box 7 on the support platform 3 can automatically tilt into the collection box 8 under the action of gravity. In the second position, the push-pull hook... The lower end of 5 abuts against the limiting roller 11, which lifts the push-pull hook 5. The driving protrusion 21 is located directly below the push-pull groove 51, which allows the driving protrusion 21 to easily engage or disengage from the push-pull groove 51. The table surface of the support platform 3 is flush with the conveying surface of the roller conveyor belt 6. In the third position, the pouring box 7 is located at the end of the roller conveyor belt 6 away from the support platform 3. The bottom surface of the pouring box 7 abuts against at least one roller. The roller conveyor belt 6 drives the pouring box 7 to move, and the roller conveyor belt 6 can convey the pouring box 7 to the support platform 3.

[0042] In this embodiment, please refer to Figures 1-4The frame 1 is provided with a slide rail 12; the slide rail 12 is preferably horizontally arranged; the support assembly includes a first support arm 22, a second support arm 23, a third support arm 24, and a triangular plate 25. The first support arm 22 and the second support arm 23 are arranged crosswise and pivotally connected at the intersection point. One end of the first support arm 22 is pivotally connected to the frame 1, and the other end of the first support arm 22 is pivotally connected to one end of the third support arm 24. The other end of the third support arm 24 is pivotally connected to one corner of the triangular plate 25; one end of the second support arm 23 is pivotally connected to the other corner of the triangular plate 25. A movable protrusion 21 is provided on the other end of the second support arm 23. A slider 26 is also provided on the other end of the second support arm 23. The slider 26 is slidably connected to the slide rail 12. The support platform 3 is fixed on the triangular plate 25. When the drive protrusion 21 is stuck in the push-pull groove 51, the push-pull hook 5 moves with the annular conveyor chain 4, which can drive the second support arm 23 to move. Through the pivot point of the first support arm 22, the second support arm 23, the third support arm 24 and the triangular plate 25, the triangular plate 25 moves accordingly, realizing the upward tilting and downward return of the support platform 3.

[0043] Based on the foregoing embodiments, please refer to Figures 1-4 The triangle 25 is preferably a right-angled triangle, which is convenient to manufacture and can better ensure that the support platform 3 is flush with the roller conveyor belt 6 after it descends and returns to its normal position. The first support arm 22 and the second support arm 23 are both non-right-angled pivotally connected to the right-angled triangle. One right-angled side of the right-angled triangle is fixed to the support platform 3, which is convenient for installation and positioning. Specifically, the first support arm 22 and the second support arm 23 should both be longer than the third support arm 24. The first support arm 22, the second support arm 23 and the third support arm 24 move synchronously, which can better realize the rising and tilting and descending and returning to normal actions of the support platform 3, and can make the angle between the platform surface of the support platform 3 and the conveying surface of the roller conveyor belt 6 exceed 90°.

[0044] In this embodiment, please refer to Figures 1-4 The limiting roller 11 is preferably rotatably mounted on the frame 1 via a bearing. The limiting roller 11 can rotate freely. The lower end of the push-pull hook 5 abuts against the limiting roller 11 during movement. The limiting roller 11 can easily make the push-pull hook 5 rise or fall. One end of the slide rail 12 is located directly above the limiting roller 11. The slider 26 stops moving after it moves directly above the limiting roller 11. At this time, the table surface of the support platform 3 is flush with the conveying surface of the roller conveyor belt 6.

[0045] In this embodiment, please refer to Figures 1-4 and Figure 6The support platform 3 should include several support rollers 32; when the annular conveyor chain 4 is in the second position, the several support rollers 32 are distributed in the horizontal direction, and the support rollers 32 support the tilting box 7 by rolling support, so that the tilting box 7 can move on the support platform 3; the opening of the limiting groove 31 faces the tilting box 7, and the height of the limiting protrusion 71 on the tilting box 7 matches that of the limiting groove 31. When the limiting protrusion 71 on the tilting box 7 moves in the direction of the limiting groove 31, it can be easily inserted into the limiting groove 31.

[0046] In this embodiment, please refer to Figures 1-4 The frame 1 is equipped with several tension sprockets 13, all of which mesh with the annular conveyor chain 4. The tension sprockets 13 support the annular conveyor chain 4. The drive component 41 is a motor, and the output shaft of the motor is connected to one of the tension sprockets 13, which can drive the annular conveyor chain 4 to move.

[0047] In this embodiment, please refer to Figures 1-5 The upper end of the push-pull hook 5 has an inclined surface facing the side of the drive protrusion 21. When the push-pull hook 5 approaches the drive protrusion 21, the inclined surface first abuts against the drive protrusion 21, so that the push-pull hook 5 can be lifted by force, and the push-pull groove 51 moves to the top of the drive protrusion 21, so that the drive protrusion 21 can be inserted into the push-pull groove 51.

[0048] Based on the foregoing embodiments, please refer to Figures 1-5 A spring 52 is fitted on the part of the push-pull hook 5 that extends from the lower end of the guide cylinder 42. The spring 52 causes the push-pull hook 5 to have a downward tendency. When the push-pull hook 5 is not subjected to external force, it can move downward quickly, ensuring that the drive protrusion 21 can be stably locked in the push-pull groove 51. Specifically, a connecting hole is provided on the outer wall of the guide cylinder 42. The screw passes through the connecting hole and is threaded to the side wall of the annular conveyor chain 4, so that the guide cylinder 42 and the push-pull hook 5 can be fixed on the annular conveyor chain 4.

[0049] It should be noted that several workstations should be provided on one side of the roller conveyor belt 6. When the roller conveyor belt 6 drives the tilting box 7 to move, the hole punch or hole punch accessories processed at each workstation can be put into the tilting box 7, which can conveniently complete the collection of hole punch or hole punch accessories from multiple workstations.

[0050] The specific working principle of this invention is as follows:

[0051] like Figure 4 As shown, the initial position of the annular conveyor chain 4 is in the third position, and the tilting box 7 is located on the roller conveyor belt 6 and away from the support platform 3. At this time, the annular conveyor chain 4 rotates counterclockwise, and the roller conveyor belt 6 drives the tilting box 7 to move closer to the support platform 3. Multiple stations sequentially put the processed hole openers or hole opener accessories into the tilting box 7.

[0052] like Figure 2 and Figure 3 As shown, the annular conveyor chain 4 moves to the second position. At this time, the annular conveyor chain 4 rotates counterclockwise, and the tilting box 7 moves onto the support platform 3. The guide cylinder 42 on the annular conveyor chain 4 abuts against the drive protrusion 21. The lower end of the push-pull hook 5 abuts against the limiting roller 11. The limiting roller 11 lifts the push-pull hook 5, and the drive protrusion 21 is located directly below the push-pull groove 51. The annular conveyor chain 4 continues to move. After the push-pull hook 5 disengages from the limiting roller 11, the push-pull hook 5 automatically descends under the action of the spring 52. The drive protrusion 21 can be inserted into the push-pull groove 51. The annular conveyor chain 4 can stably drive the drive protrusion 21 to move, so that the support platform 3 and the tilting box 7 can continuously rise and tilt.

[0053] like Figure 1 As shown, the annular conveyor chain 4 moves to the first position, the drive protrusion 21 is engaged in the push-pull groove 51, the support platform 3 is lifted to the limit position by the support assembly, the limiting protrusion 71 is engaged in the limiting groove 31, the tilting box 7 is located directly above the collection box 8, the angle between the platform surface of the support platform 3 and the conveying surface of the roller conveyor belt 6 exceeds 90°, and the hole opener or hole opener accessory in the tilting box 7 is automatically tilted into the collection box 8 under the action of gravity; then, the annular conveyor chain 4 begins to rotate clockwise, the push-pull groove 51 drives the drive protrusion 21 to move to the second position, and the support platform 3 begins to descend back to the center position;

[0054] like Figures 2-4 As shown, the annular conveyor chain 4 moves to the second position. At this time, the annular conveyor chain 4 rotates clockwise, and the lower end of the push-pull hook 5 abuts against the limiting roller 11. The limiting roller 11 lifts the push-pull hook 5, and the annular conveyor chain 4 drives the push-pull hook 5 to move. The driving protrusion 21 can disengage from the push-pull groove 51. The roller conveyor belt 6 can drive the tilting box 7 to move away from the support platform 3, and collect the hole opener or hole opener accessories at multiple workstations again, until the annular conveyor chain 4 moves to the third position.

[0055] By repeating the above steps, the present invention can automatically complete the collection and unloading process of the hole opener and its accessories using only one drive component 41. The structure is simple and the operation is convenient.

[0056] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
