Description

Technical Field

[0001] This utility model relates to the technical field of pencil production equipment, specifically a pencil board edge trimming machine. Background Technology

[0002] In the pencil production process, the pencil board (the pencil blank substrate formed by cutting wood boards) needs to be positioned on the side by an edge-gauge machine to ensure the dimensional consistency of subsequent cutting and rod-making processes.

[0003] Existing pencil board edge-correcting machines suffer from the following key technical defects, hindering production adaptability and processing quality: Firstly, the positioning components are mostly fixed structures, only suitable for pencil boards of a single width. When processing different specifications, the entire positioning frame must be disassembled and replaced, resulting in time-consuming size changes, requiring specialized tools, and cumbersome operation, making it impossible to quickly respond to the needs of multi-variety production. Secondly, the thickness control precision is insufficient, making it difficult to ensure that pencil boards are moved out individually. The positioning frame height of traditional edge-correcting machines is fixed. If the height is too large, multiple pencil boards may be stacked and pass through, affecting subsequent processing; if the height is too small, the pencil boards may get stuck, causing damage to the substrate. Furthermore, there is a lack of an effective thickness adjustment mechanism, resulting in extremely poor adaptability. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4This utility model provides a technical solution: a pencil board edge trimming machine, including a conveyor belt frame 1, with a conveyor belt 2 arranged between the two conveyor belt frames 1 via conveyor belt rollers. The conveyor belt 2 is driven by an external motor to convey pencil boards. A moving groove 3 is opened along the length direction on one side of the conveyor belt frame 1. A control box 4 is slidably connected inside the moving groove 3 with clearance fit. The control box 4 provides an installation base for subsequent adjustment components. A first threaded rod 5 is rotatably connected to the tail of the control box 4 via a deep groove ball bearing. The outer side of the first threaded rod 5 is threadedly connected to the inside of the conveyor belt frame 1. Rotating the first threaded rod 5 can drive the control box 4 to slide laterally along the moving groove 3 to achieve width adaptation of the positioning frame. A control groove 6 is opened inside one side of the control box 4. A first bevel gear 7 is rotatably connected to the middle of the control groove 6 via a deep groove ball bearing. Two sets of second bevel gears 8 are symmetrically meshed on both sides of the upper part of the first bevel gear 7. A rotating shaft 16 is fixed in the middle of the first bevel gear 7 via a key. One end of the rotating shaft 16 penetrates the control box 4 and is threaded through... A rotating cap 17 is fixedly connected to the wire. Rotating the rotating cap 17 drives the first bevel gear 7 to rotate. The tail of the second bevel gear 8 is fixedly connected to the second threaded rod 9 by a key. The tail of the second threaded rod 9 is rotatably connected to the inner wall of the control groove 6 by a deep groove ball bearing. The bevel gear transmission realizes a 90-degree change in the power direction, converting the vertical rotation of the first bevel gear 7 into the horizontal rotation of the second threaded rod 9. The outer side of the second threaded rod 9 is connected to a moving block 10 by a thread. Two sets of communicating grooves 11 are opened on one side of the control box 4, which communicate with the control groove 6. The moving block 10 is fixedly connected to the first connecting rod 12 by a screw on one side. The other end of the first connecting rod 12 penetrates the communicating groove 11 and is fixedly connected to the first lifting block 13 by a screw. The outer side of the first lifting block 13 is slidably connected to the first lifting frame 14 by a clearance fit. The other side of the first lifting frame 14 is fixedly connected to the positioning frame 15 by a screw. The inner side of the positioning frame 15 is attached with a rubber buffer pad. The positioning frame 15 is used to limit the width of the pencil board, and its height ensures that a single set of pencil boards can pass through.

[0021] The moving slot 3 has symmetrically opened limiting slots 18 on both sides. The control box 4 has a limiting block 19 fixedly connected to both ends of one side by screws. The limiting block 19 is slidably connected to the limiting slot 18 through clearance fit, which limits the sliding direction of the positioning control box 4, prevents the control box 4 from rotating with the first threaded rod 5, and ensures stable lateral adjustment.

[0022] A guide rod 20 is fixedly connected to the inside of the first lifting frame 14 on one side by screws. The outside of the guide rod 20 is slidably connected to the inside of the first lifting block 13 on one side by clearance fit. A third threaded rod 21 is rotatably connected to the inside of the first lifting frame 14 on the other side by deep groove ball bearing. The outside of the third threaded rod 21 is threadedly connected to the inside of the first lifting block 13 on the other side. A follower plate 22 is fixedly connected between the lower sides of the two first lifting frames 14 by screws. The follower plate 22 ensures that the two first lifting frames 14 rise and fall synchronously, avoids the positioning frame 15 from tilting, and ensures the accuracy of height adjustment.

[0023] The first lifting frame 14 and the positioning frame 15 are fixedly connected to the second lifting frame 23 by screws on one side. The second lifting frame 23 is slidably connected to the second lifting block 24 through clearance fit. The second lifting block 24 is fixedly connected to the second connecting rod 25 by screws on one side. The second connecting rod 25 penetrates the second lifting frame 23 and is fixedly connected to the limit plate 26 by screws. The limit plate 26 is used to fit the side of the pencil board to prevent it from shifting during movement.

[0024] Two sets of sliding rods 27 are fixedly connected to the rear side of the limiting plate 26 by screws. The sliding rods 27 are slidably connected to the inside of the conveyor belt frame 1 through clearance fit.

[0025] The conveyor belt frame 1 has two sets of sliding grooves 28 that are adapted to the sliding rod 27. The end of the sliding rod 27 that penetrates into the sliding groove 28 is fixedly connected to a limiting plate 29 by screws. The limiting plate 29 is slidably connected to the inside of the sliding groove 28 through clearance fit to prevent the sliding rod 27 from coming out of the conveyor belt frame 1 and to ensure the stable movement of the limiting plate 26.

[0026] Working principle: When using this utility model: According to the width of the pencil board to be processed, the first threaded rod 5 is rotated by hand. The first threaded rod 5 rotates relative to the conveyor belt frame 1 through the deep groove ball bearing, driving the control box 4 to slide laterally along the moving groove 3. When the control box 4 slides, the limiting blocks 19 on both sides slide synchronously along the limiting groove 18 to prevent the control box 4 from rotating and deviating. The control box 4 drives the first lifting frame 14 and the positioning frame 15 to move synchronously until the distance between the positioning frames 15 on both sides matches the width of the pencil board. When the first threaded rod 5 is stopped, due to the self-locking characteristic of the thread, the position of the control box 4 is fixed, and the lateral positioning of the positioning frame 15 is completed.

[0027] Rotate the rotating cap 17 on one side of the control box 4. The rotating cap 17 drives the first bevel gear 7 to rotate through the rotating shaft 16. The first bevel gear 7 meshes and drives the second bevel gears 8 on both sides to rotate synchronously. The second bevel gears 8 drive the second threaded rod 9 to rotate. The moving block 10 moves laterally along the second threaded rod 9. Through the first connecting rod 12, the first lifting block 13 and the first lifting frame 14, the positioning frames 15 on both sides move left and right, thereby positioning the left and right width of the pencil board.

[0028] By rotating the third threaded rod 21, the first lifting block 13 on one side slides along the guide rod 20, and the other side slides along the third threaded rod 21. The follower plate 22 ensures that the first lifting frames 14 on both sides rise and fall synchronously, thereby driving the positioning frame 15 to adjust its height. Observe the height of the positioning frame 15 and make it slightly larger than the thickness of a single pencil board. Stop rotating the rotating cap 17, and the height adjustment of the positioning frame 15 is completed.

[0029] When the height of the positioning frame 15 changes, the second lifting block 24 slides along the second lifting frame 23, and drives the limiting plate 26 to move laterally through the second connecting rod 25; the limiting plate 26 drives the sliding rod 27 to slide along the sliding groove 28 of the conveyor belt frame 1, and the limiting piece 29 prevents the sliding rod 27 from falling out; when the limiting plate 26 moves with the positioning frame 15, its inner rubber pad is in contact with the side of the pencil board, which can prevent the pencil board from shifting laterally when it moves with the conveyor belt 2.

[0030] Start the drive motor of conveyor belt 2, and conveyor belt 2 will move the pencil board towards the positioning frame 15. When the pencil board reaches the positioning frame 15, the positioning frames 15 on both sides restrict the position, and only a single pencil board passes under the positioning frame 15. After passing, the pencil board enters the next edge-correcting process to complete the positioning assistance.
