Description

Technical Field

[0001] This utility model belongs to the field of pencil processing technology, and more specifically, it relates to a pencil drying device after coating. Background Technology

[0002] Pencils are typically made of wood, and the varnish forms a protective film on the wood surface, effectively isolating it from external moisture and humidity. If wood is exposed to a humid environment for a long time, it is prone to rot and warping. The varnish layer can prevent these problems, extending the lifespan of the pencil and keeping it in good working order for an extended period.

[0003] The existing Chinese patent application number is CN202420089679.5, which discloses a pencil production drying device, comprising: a drying box, on both sides of which support blocks are provided, and a conveyor belt is installed inside the two support blocks, the conveyor belt being movably fitted together with the drying box; several mounting slots, which are respectively opened on the top and bottom surfaces inside the drying box, and two rotating shafts are rotatably installed inside the conveyor belt; and a drying assembly, which is located inside the mounting slots and is used to dry the pencils. When the conveyor belt moves inside the drying box, it facilitates the removal of the dried paper-rolled pencils from the drying box and quickly feeds the paper-rolled pencils into the drying box for drying. When the worker places the paper-rolled pencils inside the two placement slots, it ensures that the outer wall of the paper-rolled pencil can directly contact the heat, ensuring that the pencil lead is heated evenly, thereby improving the quality of the paper-rolled pencils. In practical application, after the pencil falls into the placement slot, the contact area between the pencil's paint and the slot is relatively large, which can easily damage the paint on the pencil, thus limiting its practical use.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a pencil drying device after coating, in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a pencil drying device after coating, which is achieved by the following specific technical means:

[0006] A pencil drying device after painting includes a main frame. Bending sections are provided on the top sides of both ends of the main frame, with two sets of bending sections arranged in a figure-eight shape. Two sets of rotating shafts are symmetrically connected to each bending section via bearings. Two sets of conveying mechanisms are installed on the inner side of the main frame, with adjacent sides of each conveying mechanism inclined downwards. Each conveying mechanism includes a first rotating roller and a second rotating roller, with a conveyor belt connected to the outer sides of both rollers. Rollers one and two are coaxially fixedly connected to their corresponding rotating shafts. A drying mechanism is installed on the main frame.

[0007] Furthermore, both ends of the first and second rollers are fixedly connected to a limiting plate, and the two sides of the conveyor belt abut against one side of the limiting plate.

[0008] Furthermore, the conveyor belt is provided with multiple sets of anti-slip grooves at equal intervals.

[0009] Furthermore, four sets of fixing plates are fixedly installed on the bottom side of the inner wall of the main frame. The inner side of each of the four sets of fixing plates is rotatably connected to a drive shaft. The drive shaft is coaxially fixedly connected to two sets of rotating rollers and two sets of rotating rollers respectively.

[0010] Furthermore, the two sets of drive shafts located between the two sets of rollers and the two sets of drive shafts located between the two sets of rollers are all connected by universal joints.

[0011] Furthermore, a driving wheel and a driven wheel are rotatably connected to one side of the main frame. One end of each of the two sets of rotating shafts passes through one side of the main frame and is fixedly connected to one side of the driving wheel and the driven wheel, respectively. The driving wheel and the driven wheel are connected by a synchronous belt drive. A protective housing is installed on the outside of the driving wheel and the driven wheel. A drive motor is fixedly installed on one side of the protective housing. The output end of the drive motor passes through one side of the protective housing and is fixedly connected to one side of the driving wheel on the same axis.

[0012] Furthermore, the drying mechanism includes a cover plate fixedly connected to the top side of the main frame, a hot air blower fixedly installed on the top side of the cover plate, the output end of the hot air blower passing through the cover plate and corresponding to the two sets of conveying mechanisms; and support frames fixedly installed on the four corners of the bottom side of the main frame.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention, through the combination of a bent section and a rotating shaft, allows for the tilted installation of two sets of conveyor mechanisms. This reduces the contact area between the pencil and the conveyor belt when the pencil falls onto the two sets of conveyor mechanisms, ensuring that only a corner of the pencil's end contacts the conveyor belt. This prevents damage to the pencil's paint surface during conveying and drying, thus increasing the product's practicality.

[0015] This invention, through the cooperation of a drive motor, a driving wheel, a driven wheel, and a synchronous belt, can drive two rollers to rotate simultaneously. Through the cooperation of a transmission shaft and a universal joint, it can enable two sets of conveying mechanisms to operate simultaneously through one drive motor, thereby reducing the production cost of the product.

[0025] As attached Figure 1 To be continued Figure 4 As shown:

[0026] This utility model provides a pencil drying device after painting, including a main frame 1. Both ends of the main frame 1 have bent sections on their top sides, arranged in a figure-eight shape. Two sets of rotating shafts 2 are symmetrically connected to each bent section via bearings. Two conveying mechanisms are installed on the inner side of the main frame 1, with adjacent sides of each conveying mechanism inclined downwards. Each conveying mechanism includes a first rotating roller 3 and a second rotating roller 4. A conveyor belt 5 is connected to the outer sides of both the first rotating roller 3 and the second rotating roller 4. The first rotating roller 3 and the second rotating roller 4 are coaxially fixedly connected to their respective rotating shafts 2. A drying mechanism is installed on the main frame 1.

[0027] Both ends of the first roller 3 and the second roller 4 are fixedly connected to a limiting plate 6, and both sides of the conveyor belt 5 abut against one side of the limiting plate 6 to prevent the conveyor belt 5 from deviating during operation.

[0028] The conveyor belt 5 is provided with multiple sets of anti-slip grooves at equal intervals, which can effectively move the pencil and prevent it from shaking or slipping.

[0029] Four sets of fixing plates 7 are fixedly installed on the bottom inner wall of the main frame 1. The inner side of each of the four sets of fixing plates 7 is rotatably connected to a drive shaft. The drive shaft is coaxially fixedly connected to two sets of rotating rollers 3 and two sets of rotating rollers 4, respectively, to increase the stability of the conveying mechanism when it is fixed.

[0030] The two sets of drive shafts located between the two sets of rotating rollers 3 and the two sets of drive shafts located between the two sets of rotating rollers 4 are all connected by universal joints 8, which can realize the drive connection of the two sets of rotating rollers 3 and the drive connection of the two sets of rotating rollers 4.

[0031] The main frame 1 has a drive wheel 9 and a driven wheel 10 rotatably connected to one side. One end of each of the two sets of rotating shafts 2 passes through one side of the main frame 1 and is fixedly connected to one side of the drive wheel 9 and the driven wheel 10, respectively. The drive wheel 9 and the driven wheel 10 are connected by a synchronous belt 11, which can drive the first rotating roller 3 and the second rotating roller 4 to rotate synchronously. A protective housing 12 is installed on the outside of the drive wheel 9 and the driven wheel 10 to protect the drive wheel 9, the driven wheel 10 and the synchronous belt 11. A drive motor 13 is fixedly installed on one side of the protective housing 12. The output end of the drive motor 13 passes through one side of the protective housing 12 and is fixedly connected coaxially to one side of the drive wheel 9, which can drive the drive wheel 9 to rotate automatically.

[0032] The drying mechanism includes a cover plate 14 fixedly connected to the top side of the main frame 1. A hot air blower 15 is fixedly installed on the top side of the cover plate 14. The output end of the hot air blower 15 passes through the cover plate 14 and is set corresponding to two sets of conveying mechanisms, which can quickly dry the pencils. Support frames 16 are fixedly installed on the four corners of the bottom side of the main frame 1 to increase the horizontal height of the main frame 1.

[0033] The working principle of this embodiment is as follows: When the pencils need to be dried, the electrical components such as the drive motor 13 and the hot air blower 15 in the product are connected to an external power supply and control unit. The drive motor 13 and the hot air blower 15 are started. At this time, the drive motor 13 drives the drive wheel 9 to rotate. The drive wheel 9 is driven by the synchronous belt 11 and the driven wheel 10, and drives the first roller 3 and the second roller 4 to rotate. The first roller 3 and the second roller 4 drive the conveyor belt 5 to operate, and drive the two sets of conveying mechanisms to operate through the universal joint 8. When the pencils that have been painted are put into the feeding end of the conveying mechanism, only one corner of each end of the pencil contacts the conveying mechanism, which can effectively prevent large-area damage to the paint surface of the pencil. The hot air blower 15 dries the pencils until all the pencils are dried.
