Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of stationery processing, and in particular to a device for sealing pen refills with wax. Background Technology
[0002] The waxing and capping process for pen refills is a crucial step in forming a wax layer on the pen tip to seal the ink, prevent oxidation, and provide physical protection for the pen nib. Traditional methods use hot-melt wax (such as modified polyester / polyamide) applied at high temperatures (150-200℃). Existing waxing and capping devices are inefficient at sealing pen refills, resulting in poor sealing effects. Furthermore, the inconsistent contact time between the pen refill and the wax during the waxing process can damage the refill and lead to processing quality issues. Utility Model Content
[0003] The present invention aims to overcome the shortcomings of low processing efficiency and poor results in the existing technology, and provides a pen refill wax sealing device with high processing efficiency and good results.
[0004] To achieve the above objectives, this utility model adopts the following technical solution: a pen refill wax sealing device, comprising:
[0005] A conveyor belt for transporting pen refills;
[0006] A wax-turning wheel is located on the right side of the conveyor belt and is rotatable. A wax-pouring tank is provided above the wax-turning wheel.
[0007] A core-pushing mechanism, located on the left side of the conveyor belt, is used to push the pen core to the right to apply wax.
[0008] A reset mechanism is used to retract and reset the pen refill after waxing is completed. The reset mechanism is located between the conveyor belt and the wax-turning wheel.
[0009] This device includes a conveyor belt for transporting pen refills, enabling assembly line operation. A rotating wax-turning wheel is positioned on the right side of the conveyor belt. Above the wheel is a wax-pouring tank that continuously pours heated molten wax onto the wheel. The rotation of the wheel transfers the wax to the side closer to the conveyor belt. On the left side of the conveyor belt is a refill-pushing mechanism that pushes the pen refill to the right, bringing its tip into contact with the wax on the wheel to complete the waxing and capping process. Simultaneously, a resetting mechanism is located between the conveyor belt and the wax-turning wheel. This mechanism retracts the wax-capped pen refill back to its original position on the conveyor belt, ensuring immediate retraction after waxing to prevent damage from high temperatures and maintain production quality. The combination of the wax-turning wheel and the pushing mechanism allows for simultaneous waxing of multiple pen refills, improving processing efficiency. The resetting mechanism also protects the pen refills, further enhancing the overall processing effectiveness.
[0010] Preferably, the conveyor belt is provided with a plurality of positioning blocks, and the pen refill is placed within the positioning blocks. Specifically, the plurality of positioning blocks arranged at equal intervals on the conveyor belt serve to position the pen refill, ensuring assembly line operation and guaranteeing processing efficiency and quality.
[0011] Preferably, the wax-turning wheel is equipped with fixing plates on both sides, and a drive motor is mounted on the outer side of the fixing plates, connected to the wax-turning wheel. The fixing plates on both sides of the wax-turning wheel, with the drive motors connected to them, allow the wax-turning wheel to rotate, transferring the wax liquid to the side closer to the conveyor belt. Simultaneously, the rotation of the wax-turning wheel helps to cool the wax liquid, preventing it from overheating and affecting the waxing and sealing effect.
[0012] Preferably, the wax-turning wheel has several wax storage tanks on its sidewall, and each wax storage tank has a vertical plate at its end. The vertical plate has several wax-dispensing openings for inserting the pen refill. The wax storage tanks on the sidewall of the wax-turning wheel store wax and facilitate its transfer to the conveyor belt. The vertical plate at the end of each wax storage tank has several wax-dispensing openings. These openings position the pen refill during wax dispensing, allowing the wax squeezed out from the opening to seal the pen refill. This structure ensures effective wax sealing and guarantees the processing quality of the device.
[0013] Preferably, the pusher mechanism includes a pusher cylinder connected to a pusher plate, which contacts the pen refill. The pusher cylinder, with its telescopic end connected to the pusher plate, contacts the pen refill. Its pushing action moves the pen refill towards the wax wheel, achieving the wax application and capping operation. The length of the pusher plate is sufficient to push multiple pen refills, thereby improving processing efficiency.
[0014] Preferably, the reset mechanism is provided with a mounting plate and a sliding plate at the top. The lower end of the sliding plate is connected to a telescopic rod, and the telescopic rod is connected to a limiting plate for locking and limiting the pen refill. The mounting plate is connected to a fixing plate, and a guide rod is connected to the top outer side of the mounting plate. The sliding plate is provided with a guide hole, and the guide hole is sleeved with the guide rod. A spring is sleeved on the guide rod, and the spring is placed between the mounting plate and the sliding plate. The reset mechanism includes a mounting plate and a sliding plate. The mounting plate is connected to a fixed plate and arranged parallel to the sliding plate. A guide rod is mounted on the mounting plate, and a guide hole is provided on the sliding plate. The guide hole is sleeved with the guide rod. A spring is sleeved on the guide rod, and both ends of the spring are connected to the mounting plate and the sliding plate, respectively. A telescopic rod is mounted on the lower end of the sliding plate, and a limit plate is connected to the lower end of the telescopic rod. The telescopic rod can drive the limit plate to press down, so that the limit plate can limit the tip of the pen refill. This ensures that when the refill pusher mechanism pushes the pen refill to move towards the wax wheel, the limit plate and the sliding plate move towards the wax wheel in a straight line. When the pen tip enters the wax dispensing port, the sliding plate compresses the spring to its limit, limiting the movement of the pen refill. At the same time, under the action of the spring, after the pen refill is waxed and sealed, the refill pusher mechanism retracts, and the spring pushes the sliding plate backward, avoiding prolonged contact between the pen refill and the wax liquid, preventing damage to the pen refill due to excessive temperature, thereby improving the processing effect and ensuring the processing quality.
[0015] Preferably, the limiting plate is a U-shaped plate with several limiting grooves on its side wall, allowing the pen refill to engage with these grooves. Specifically, the limiting plate, being U-shaped, has several limiting grooves on its side wall, the number of which is the same as the number of wax dispensing openings. These grooves limit the protrusion at the tip of the pen refill, ensuring that the pen refill retracts synchronously with the limiting plate during retraction, thus protecting the pen refill and improving processing efficiency and quality.
[0016] Preferably, the inner wall of the limiting plate is provided with a guide slope. The guide slope on the inner wall of the limiting plate ensures that when the limiting plate is pressed down with the telescopic rod, the guide slope of the limiting plate can contact the tip protrusion at the front end of the pen refill, thereby tidying up the pen refill, ensuring the neatness of the pen refill when it moves towards the waxing port, ensuring the waxing and sealing effect of the pen refill, and ensuring the processing quality.
[0017] The advantages of this utility model are: good processing effect, high processing efficiency, and guaranteed processing quality. Attached Figure Description

[0025] Example 1, such as Figure 1-3As shown, a pen refill wax sealing device includes: a conveyor belt 1 for transporting pen refills; a wax-turning wheel 2, which is located on the right side of the conveyor belt 1 and is rotatable, with a wax-pouring tank 3 above the wax-turning wheel 2; a refill-pushing mechanism 4, which is located on the left side of the conveyor belt 1 and is used to push the pen refill to the right for wax application; and a reset mechanism 5, which is used to retract and reset the pen refill after wax application, and is located between the conveyor belt 1 and the wax-turning wheel 2.
[0026] The conveyor belt 1 is provided with a plurality of positioning blocks 10, and the pen refill is placed in the positioning block 10.
[0027] The wax-turning wheel 2 has fixing plates 20 installed on both sides, and a drive motor 21 is installed on the outside of the fixing plates 20. The drive motor 21 is connected to the wax-turning wheel 2.
[0028] The wax roller 2 has several wax storage grooves 22 on its side wall, and the side wall end of the wax storage groove 22 is provided with a vertical plate 23, and the vertical plate 23 is provided with several wax dispensing ports 24 for pen refill insertion.
[0029] The refill mechanism 4 includes a push cylinder 40, which is connected to a push plate 41, and the push plate 41 contacts the pen refill.
[0030] The reset mechanism 5 is provided with a mounting plate 50 and a sliding plate 51 placed at the top. The lower end of the sliding plate 51 is connected to a telescopic rod 52. The telescopic rod 52 is connected to a limiting plate 53 for locking and limiting the pen refill. The mounting plate 50 is connected to the fixing plate 20. The top outer side of the mounting plate 50 is connected to a guide rod 54. The sliding plate 51 is provided with a guide hole 55. The guide hole 55 is sleeved with the guide rod 54. The guide rod 54 is sleeved with a spring 56. The spring 56 is placed between the mounting plate 50 and the sliding plate 51.
[0031] The limiting plate 53 is a U-shaped plate, and the side wall of the limiting plate 53 is provided with a plurality of limiting grooves 57, and the pen refill is engaged with the limiting grooves 57.
[0032] The inner wall of the limiting plate 53 is provided with a guide slope 58.
[0033] The working principle of this utility model is as follows: Figure 1-3As shown, this device includes a conveyor belt 1 for transporting pen refills, enabling assembly line operation. A wax-turning wheel is located on the right side of conveyor belt 1. This wheel is rotatable, and a wax-pouring tank is positioned above it. The tank continuously pours heated molten wax onto the wheel, which, through rotation, transfers the wax closer to conveyor belt 1. A refill-pushing mechanism 4 is located on the left side of conveyor belt 1. This mechanism pushes the pen refill to the right, bringing its tip into contact with the wax on the wheel, completing the waxing and capping operation. Simultaneously, a reset mechanism 5 is located between conveyor belt 1 and the wax-turning wheel. This mechanism retracts the wax-capped pen refill back to its original position on conveyor belt 1, ensuring immediate retraction after waxing to prevent damage from high temperatures and maintain production quality. The device is equipped with a wax-turning wheel and a core-pushing mechanism 4, which can simultaneously apply wax to multiple pen refills, thus improving processing efficiency. At the same time, the reset mechanism 5 can protect the pen refills, thereby improving the effect of the processing.
[0034] Among them, a number of positioning blocks 10 are arranged at equal intervals on the conveyor belt 1. The positioning blocks 10 can play the role of positioning the pen refill, ensuring assembly line operation and ensuring processing efficiency and processing effect.
[0035] The wax-turning wheel is equipped with a fixing plate 20 on both sides, and a drive motor 21 is installed on the fixing plate 20. The drive motor 21 is connected to the wax-turning wheel and can drive the wax-turning wheel to rotate, thereby transferring the wax liquid to the side closer to the conveyor belt 1. At the same time, when the wax-turning wheel rotates, it can cool the wax liquid to a certain extent, so as to avoid the wax liquid temperature being too high and affecting the waxing and sealing effect.
[0036] The device includes several wax storage tanks 22 on the side wall of the wax-turning wheel. These tanks store wax and transport it to the side of the conveyor belt 1. A vertical plate 23 is installed on the end side wall of the wax storage tank 22. The vertical plate 23 has several wax dispensing nozzles 24. These nozzles provide positioning for the wax dispensing operation of the ejected pen refill. After the pen refill is inserted into the nozzle 24, the wax squeezed out from the nozzle 24 seals the pen refill. This structure ensures the wax sealing effect and guarantees the processing effect of the device.
[0037] The pusher mechanism 4 includes a pusher cylinder 40, the telescopic end of which is connected to a pusher plate 41. The pusher plate 41 contacts the pen refill, and its push-out action can drive the pen refill to move towards the wax wheel to achieve the waxing and capping operation. The length of the pusher plate 41 can meet the needs of pushing multiple pen refills, thereby improving processing efficiency.
[0038] The reset mechanism 5 includes a mounting plate 50 and a sliding plate 51. The mounting plate 50 is connected to the fixed plate 20 and is arranged parallel to the sliding plate 51. A guide rod 54 is provided on the mounting plate 50, and a guide hole 55 is provided on the sliding plate 51. The guide hole 55 is sleeved with the guide rod 54. A spring 56 is sleeved on the guide rod 54, and both ends of the spring 56 are connected to the mounting plate 50 and the sliding plate 51, respectively. A telescopic rod 52 is installed at the lower end of the sliding plate 51, and a limit plate 53 is connected to the lower end of the telescopic rod 52. The telescopic rod 52 can drive the limit plate 53 to press down. A support guide plate is provided below the limit plate 53, so that... The limiting plate 53, in conjunction with the support guide plate, can limit the tip of the pen refill, ensuring that when the pusher mechanism 4 pushes the pen refill towards the wax-turning wheel, the limiting plate 53 and the sliding plate 51 move towards the wax-turning wheel in a straight line. When the pen tip enters the wax-dispensing port 24, the sliding plate 51 compresses the spring 56 to its limit, limiting the movement position of the pen refill. At the same time, under the action of the spring 56, after the pen refill is waxed and sealed, the pusher mechanism 4 retracts, and the spring 56 pushes the sliding plate 51 backward, avoiding prolonged contact between the pen refill and the wax liquid, preventing damage to the pen refill due to excessive temperature, thereby improving the processing effect and ensuring the processing quality.
[0039] The limiting plate 53 is a U-shaped plate, and several limiting grooves 57 are provided on the side wall of the limiting plate 53. The number of limiting grooves 57 is the same as the number of wax dispensing openings 24. The limiting grooves 57 can limit the protrusion at the tip of the pen refill, ensuring that the limiting plate 53 can drive the pen refill to retract synchronously when it retracts, thereby protecting the pen refill, improving the processing effect, and ensuring the processing quality.
[0040] The guide slope 58 provided on the inner wall of the limiting plate 53 can ensure that when the limiting plate 53 is pressed down with the telescopic rod 52, the guide slope 58 of the limiting plate 53 can contact the tip protrusion at the front end of the pen refill, thereby tidying up the pen refill, ensuring the neatness of the pen refill when it moves towards the waxing port 24 for waxing, ensuring the waxing and sealing effect of the pen refill, and ensuring the processing quality.
