Description

Technical Field

[0001] The utility model relates to the field of pencil sawing machines, and particularly relates to a high-speed pencil sawing machine. Background Technique

[0002] A pencil sawing machine, as an important automated device in the pencil manufacturing industry, focuses on precisely cutting the pencil rod to a preset length and is a key link in the later-stage processing of the production line. Through efficient operation, it not only improves production efficiency but also ensures the precise uniformity of pencil dimensions. During operation, the pencil rod is smoothly conveyed to the saw bed area via a conveyor belt, and the saw blade rotates at high speed to precisely complete the cutting task. And all these precise operations are inseparable from the careful regulation of the control system, which flexibly adjusts the saw blade speed and cutting length to easily meet the production requirements of different specifications of pencils.

[0003] However, in the face of diverse market demands, sometimes it is necessary to saw the pencil into half-sections of different lengths, which poses a higher challenge to the pencil sawing machine. Currently, most pencil sawing machines still rely on manual operation when adjusting the sawing length, which is not only inefficient but also difficult to avoid errors, resulting in inconsistent lengths of the half-section pencils and affecting the product quality and appearance. In mass production, this problem is particularly prominent, which may lead to the appearance of a large number of unqualified products, thereby increasing production costs.

[0004] In addition, the stable clamping of the pencil during the sawing process is also a link that cannot be ignored. If the clamping is not firm, the pencil is prone to shaking during sawing, directly affecting the sawing accuracy and even causing local damage to the pencil, reducing the product quality. The rationality of the clamping structure design is also crucial. An unreasonable design may cause the pencil to deform during clamping, thereby affecting its use effect. Therefore, optimizing the sawing length adjustment mechanism and clamping structure design of the pencil sawing machine is of great significance for improving product quality and reducing production costs. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a high-speed pencil sawing machine, which can effectively solve the problems put forward in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A high-speed pencil sawing machine includes a housing, a driving motor, a speed reducer, and a circular saw blade. The driving motor is installed inside the housing, a speed reducer is installed at the output end of the driving motor, and the circular saw blade is installed at the output end of the speed reducer through a nut. The sawing of the pencil is achieved through the circular saw blade.

[0008] A ball screw assembly is installed at the lower end of the housing, and a pencil clamp is installed on the slide table of the ball screw assembly. Three extension clamping columns are installed on the pencil clamp, and a clamping screw is installed on each extension clamping column. The three extension clamping columns and the pencil clamp form a clamping groove for clamping the pencil, and the pencil is clamped by rotating the clamping screw;

[0009] Two parallel slide rods are installed on the ball screw assembly, and a moving table is installed on the two parallel slide rods. A pencil clamp identical to the slide table is installed under the moving table. The pencil is clamped by the two pencil clamps. Loosen the pencil clamp under the slide table and push the pencil under the moving table to adjust the distance, facilitating the distance adjustment and sawing of the pencil.

[0010] As a further optional solution of the present invention, a stabilizing rod is provided at the tail end of the driving motor, and the stabilizing rod extends to the rear end of the housing. Heat dissipation holes are provided at the rear end of the housing to facilitate the heat dissipation of the driving motor. The housing and the ball screw assembly are fixed by bolts;

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] In the present invention, the circular saw blade is precisely aligned with the central axis of the clamping groove of the pencil clamp, ensuring the precise positioning of the pencil during the sawing process, making the cutting more accurate and improving the product quality. The pencil clamp adopts a jaw design, which, in cooperation with the three extension clamping columns and the clamping screw, can clamp the pencil more tightly, preventing sliding or deviation during the sawing process and ensuring the stability of the cutting. By rotating the clamping screw, the clamping and releasing of the pencil can be easily achieved, greatly simplifying the operation process and improving the work efficiency.

[0017] The design of the mobile station and the sliding rod enables the device to hold a pencil simultaneously, and by adjusting the distance between the two pencil clamps, the distance adjustment and sawing of the pencil can be easily achieved, meeting the cutting requirements of pencils of different lengths.

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figure 1 - Figure 4 shown, a highly efficient pencil sawing device integrates a number of precision components, mainly including a housing 1, a power source drive motor 2, a transmission speed regulation device reducer 3 and a key sawing component circular saw blade 4. The drive motor 2 is firmly arranged in the internal space of the housing 1, and its power output end is cleverly connected to the reducer 3 to achieve smooth power transmission and precise speed regulation. The circular saw blade 4 is fixed to the output shaft end of the reducer 3 by means of a precision nut and is responsible for performing the sawing operation of the pencil, demonstrating excellent cutting performance.

[0025] To further enhance the practicality and flexibility of the device, a ball screw assembly 5 is specially equipped at the bottom of the outer shell 1. A pencil clamp 8 is tightly mounted on the slide table of this assembly. The pencil clamp 8 is ingeniously designed. It is equipped with three extended clamping posts 9 distributed in a triangle, and each extended clamping post 9 is equipped with a clamping screw 10. This design not only ensures the firm clamping of the pencil but also easily realizes the clamping and release of the pencil by rotating the clamping screw 10, greatly improving the operation convenience. At the same time, the three extended clamping posts 9 and the pencil clamp 8 together form a clamping groove 11, providing an accurate clamping space for the pencil.

[0026] In addition, the ball screw assembly 5 is also cleverly provided with two parallel slide rods 6, and a moving table 7 is slidably mounted on the slide rods 6. The same pencil clamp 8 as that on the slide table is also configured below the moving table 7. This design enables the device to clamp pencils simultaneously and easily realizes the distance adjustment and sawing of the pencils by adjusting the distance between the two pencil clamps 8. The user only needs to perform simple operations to adjust the sawing length of the pencil according to actual needs, greatly improving the work efficiency.

[0027] This device also performs excellently. A stabilizing rod is added to the tail end of the drive motor 2, effectively enhancing the overall stability of the device. At the same time, heat dissipation holes are opened at the rear end of the outer shell 1 to ensure good heat dissipation of the drive motor 2 during operation and extend the service life of the device. The outer shell 1 and the ball screw assembly 5 are firmly connected by bolts, and rubber gaskets are provided at the connection to reduce vibration and noise. The pencil clamp 8 and the slide table of the ball screw assembly 5 are also fixed by bolts to ensure the stability and reliability of the clamp.

[0028] The pencil clamp 8 adopts a jaw design, which can clamp the pencil more tightly and prevent sliding or offset during the sawing process. The rubber sleeves on the surfaces of the three extended clamping posts 9 further improve the clamping comfort and stability. The end of the clamping screw 10 is designed as an anti-slip rotating head, which is convenient for users to operate and is not easy to slip.

[0029] The central axes of the clamping grooves 11 of the two pencil clamps 8 are accurately set at the lower edge of the circular saw blade 4. This design ensures the accurate positioning and efficient cutting of the pencil during the sawing process. At the same time, the smooth design between the moving table 7 and the two slide rods 6 also reduces the sliding resistance and improves the running smoothness of the device.

[0030] Usage process: Confirm that the device outer shell 1 is stably placed on the workbench, the power supply is connected and in a safe state. Check whether the key components such as the drive motor 2, the transmission speed regulation device reducer 3, the circular saw blade 4, and the ball screw assembly 5 are intact, and all connections are tightly reliable.

[0031] Open the top or side of the outer shell 1 (depending on the specific design), and place the pencil in the clamping groove 11 of one of the pencil clamps 8. By rotating the clamping screw 10, using the jaw design on the extended clamping post 9, tightly clamp the pencil in the clamping groove 11. If necessary, repeat the above steps to install the pencil on the other pencil clamp 8 and adjust the distance between the two clamps as needed.

[0032] Utilize the sliding rod 6 and the moving table 7 of the ball screw assembly 5 to adjust the relative position between the two pencil clamps 8, thereby determining the length of the sawn pencil. Ensure that the moving table 7 slides smoothly without abnormal resistance.

[0033] Connect the power supply, press the start button, and the driving motor 2 starts to operate. The motor power is smoothly transmitted to the circular saw blade 4 through the speed reducer 3, and the circular saw blade 4 starts to rotate.

[0034] On the premise of ensuring safety, slowly push or move the clamped pencil to make it approach the rotating circular saw blade 4. The circular saw blade 4 quickly and accurately saws off the pencil, and the pencil should remain stable without shaking during the cutting process.

[0035] After sawing is completed, turn off the power supply of the device and wait for the circular saw blade 4 to completely stop rotating. Gently loosen the clamping screw 10, and take out the sawn pencil from the pencil clamp 8. Collect the finished pencils at the designated location for the next step of processing or packaging.

[0036] Clean the sawdust and impurities on the device outer shell 1, the circular saw blade 4, and the pencil clamps 8. Check whether each component has wear or looseness, and perform repairs or replacements in a timely manner. Regularly lubricate and maintain the device to ensure that the transmission system is smooth and unobstructed. Then, the pencil sawing machine can be used efficiently and accurately to complete the sawing operation of the pencil.
