Description

Technical Field

[0001] The present invention relates to the technical field of pen refill production equipment, and particularly relates to a pen refill centrifugal exhaust device. Background Art

[0002] A pen refill is an important component structure of a ballpoint pen and a gel pen. During the production process of a pen refill, ink needs to be filled into the core tube, and the pen tip is installed at the end of the core tube. Then, the assembled pen refill is placed inside a centrifuge, and the air filled in the ink is discharged by using the centrifugal force of the centrifuge, so as to avoid affecting the writing effect due to the air blocking the flow of the ink in the core tube.

[0003] Currently, when performing centrifugal operation on pen refills, generally, multiple pen refills are bundled together, and then the bundled pen refills are simultaneously inserted into a box. Then, the box containing the pen refills needs to be passed through the top opening of the centrifuge one by one and extended into the interior of the centrifuge, and then stacked and inserted on the inner wall of the centrifuge. Using this centrifuge to perform centrifugal exhaust on pen refills will make the process of putting in and taking out the pen refills very cumbersome, reducing the production efficiency of pen refills.

[0004] In summary, there is a need for a pen refill centrifugal exhaust device that is convenient for putting in and taking out pen refills. Summary of the Invention

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] Embodiment 1

[0031] To solve the technical problems in the background art, a refill centrifugal exhaust device is provided as follows:

[0032] Combined with Figures 1-8 As shown, a refill centrifugal exhaust device provided by the present invention includes an outer barrel 2. A driving mechanism 1 is connected to the bottom surface of the outer barrel 2. A support ring 3 is sleeved on the outer wall of the outer barrel 2. A retaining ring 21 is inserted into the inner wall of the outer barrel 2. The top surface of the outer barrel 2 is flush with the top surfaces of the support ring 3 and the retaining ring 21. A pneumatic rod 6 is fixed to the outer wall of the outer barrel 2. The telescopic top end of the pneumatic rod 6 penetrates through the support ring 3 and is connected to a barrel cover 4. An exhaust rack 5 is connected inside the barrel cover 4. A centrifugal barrel 8 is arranged inside the outer barrel 2. The rotating end of the driving mechanism 1 penetrates through the outer barrel 2 and is connected to the bottom surface of the centrifugal barrel 8. The exhaust rack 5 is inserted into the centrifugal barrel 8 in a matching manner. Multiple groups of storage mechanisms 7 are arranged inside the exhaust rack 5. The storage mechanism 7 is a separable structure for containing the refill 9;

[0033] The driving mechanism 1 includes a motor 11, a base 12, a first transmission wheel 13, a transmission belt 14, a second transmission wheel 15, and a rotating shaft 16. The base 12 is arranged on the bottom surface of the outer barrel 2. The motor 11 is arranged on the top surface of the base 12. The bottom end of the rotating shaft of the motor 11 is connected to the first transmission wheel 13. The top end of the rotating shaft 16 penetrates through the outer barrel 2 and is connected to the bottom surface of the centrifugal barrel 8. The bottom end of the rotating shaft 16 is connected to the second transmission wheel 15. A transmission belt 14 is sleeved between the outer walls of the first transmission wheel 13 and the second transmission wheel 15;

[0034] After loading multiple pen refills 9 into the storage mechanism 7 in a separated state, the storage mechanism 7 is retracted and clamped to store the pen refills 9, and placed on the support ring 3 to be ready for loading into the centrifugal barrel 8. Then, the pneumatic rod 6 is used to push the barrel cover 4 to rise. At the same time, the exhaust rack 5 extends upward from the inside of the centrifugal barrel 8. Then, multiple groups of storage mechanisms 7 are loaded into the exhaust rack 5. Then, the exhaust rack 5 is lowered and retracted into the centrifugal barrel 8. The driving mechanism 1 is started to make the centrifugal barrel 8 drive the storage mechanism 7 on the exhaust rack 5 to rotate. Finally, the air inside the pen refills 9 in the storage mechanism 7 is discharged by centrifugal force. Thus, by using the separable storage mechanism 7 and the exhaust rack 5 that moves up and down inside the centrifugal barrel 8, the operation method of loading the pen refills 9 into the centrifugal barrel 8 for centrifugation is more convenient and efficient.

[0035] As an improvement of the above technical solution, the exhaust rack 5 includes a stop block 51, a support column 52, and a support disk 53. The support column 52 is connected through the center of the inside of the barrel cover 4. The top end of the support column 52 is connected to the stop block 51. The stop block 51 is attached to the top surface of the barrel cover 4. The support disk 53 is sleeved on the outer wall of the support column 52. The support disk 53 is cooperatively inserted into the inside of the centrifugal barrel 8. There are two support disks 53 arranged at intervals. Multiple groups of storage mechanisms 7 are inserted into the top surfaces of both support disks 53;

[0036] By moving the support disks 53 one by one so that their top surfaces are flush with the top surface of the retaining ring 21, and then pushing the storage mechanisms 7 to be respectively inserted on the two support disks 53 of the support column 52, the pen refills 9 can be loaded in layers. The loading operation is convenient, and more pen refills 9 can be centrifugally exhausted at the same time, improving the production efficiency.

[0037] As an improvement of the above technical solution, a guide post 81 is fixed on the inner wall of the centrifugal barrel 8. A plurality of guide posts 81 are arranged at intervals along the circumferential inner wall of the centrifugal barrel 8. The storage mechanism 7 is cooperatively inserted between two guide posts 81. A plurality of card slots 531 for the guide posts 81 to be cooperatively inserted are formed on the side wall of the support disk 53;

[0038] By utilizing the mating insertion of the guide posts 81 and the card slots 531, the support plate 53 can slide up and down along the guide posts 81 on the inner wall of the centrifuge barrel 8, and the storage mechanism 7 is guided and inserted between the two guide posts 81 for limitation, improving the accuracy and stability of the placement position of the storage mechanism 7.

[0039] As an improvement of the above technical solution, the distance between the support plate 53 and the barrel cover 4 is equal to the height of the storage mechanism 7, the distance between the two support plates 53 is equal to the height of the storage mechanism 7, a first limit block 532 is fixed on the top surface of the support plate 53, a plurality of the first limit blocks 532 are fixed along the circumferential direction of the support plate 53, the first limit block 532 is of a concave structure, and the storage mechanism 7 is inserted into the groove of the first limit block 532;

[0040] After the storage mechanism 7 is respectively inserted into the top surfaces of the two support plates 53, the first limit block 532 is used to limit the further movement of the storage mechanism 7 in the horizontal direction, and the top surfaces of the storage mechanisms 7 on the two support plates 53 are respectively in contact with the bottom surface of the barrel cover 4 and the bottom surface of the other support plate 53, restricting the movement of the storage mechanism 7 in the vertical direction. After the storage mechanism 7 enters the centrifuge barrel 8 along with the support plate, it can be accurately inserted between the two guide posts 81 for further limitation, improving the accuracy of the centrifugal position of the storage mechanism 7, so as to ensure that the pen refills 9 in each storage mechanism 7 have the same centrifugal force and can obtain the same centrifugal effect.

[0041] Embodiment 2

[0042] As Figures 5-8 shown, on the basis of the above embodiment, the present embodiment further gives the following content:

[0043] To make the loading and unloading of multiple pen refills 9 in each storage mechanism 7 more stable and convenient, the traditional bundling method of the pen refills 9 is cancelled, and the pen refills 9 are directly clamped inside the storage mechanism 7. The following design is given in this embodiment:

[0044] The storage mechanism 7 includes a box body 71, clamping plates 74 and a backing plate 75. An opening is provided on the side wall of the box body 71. One side of the box body 71 with the opening is inserted into the first limit block 532. The backing plate 75 is inserted and matched inside the box body 71. The side wall of the backing plate 75 is connected with the clamping plates 74. Two clamping plates 74 are arranged in parallel, and the two clamping plates 74 are respectively attached to the two inner walls of the box body 71. The side wall of the clamping plate 74 is flush with the end face of the box body 71 with the opening;

[0045] When loading the pen refills 9 into the box body 71, the pen refills 9 are clamped and positioned by the clamping plates 74 on both sides inside the box body 71, and the whole pen refills 9 are inserted into the box body 71, ensuring the stability of the pen refills 9 during centrifugation after being loaded into the box body 71.

[0046] When removing the refill 9 from the inside of the cartridge body 71, by pulling the two clamping plates 74 at the opening of the cartridge body 71, the backing plate 75 is driven to be pushed out from the inside of the cartridge body 71. The inserted refill 9 is pushed out from the inside of the cartridge body 71 by using the backing plate 75, facilitating the complete removal of the refill 9 fully loaded into the cartridge body 71 and allowing it to fall downward between the two clamping plates 74. The removal operation is convenient and fast.

[0047] As an improvement of the above technical solution, the clamping plate 74 is of an L-shaped structure and is divided into an inner plate and an outer plate. The inner plate is a spring plate. A slot 711 is formed in the opening end face of the cartridge body 71, and the outer plate is inserted into the slot 711.

[0048] When the refill 9 is inserted between the two clamping plates 74, the inner plate made of spring plate material clamps the refill 9 until the outer plate is inserted into the slot 711 to clamp and position the refill 9, ensuring the stability of the clamping of the refill 9 by the clamping plate 74.

[0049] As an improvement of the above technical solution, the storage mechanism 7 further includes a side push plate 72 and a sliding guide assembly 73. The sliding guide assembly 73 is arranged on the side wall of the cartridge body 71. There are two groups of the sliding guide assembly 73 symmetrically arranged on both sides of the cartridge body 71. The side push plate 72 is slidably inserted into the sliding guide assembly 73, and the end of the side push plate 72 is connected to the side wall of the outer plate.

[0050] By guiding and pushing and pulling the side push plate 72 inside the sliding guide assembly 73, the clamping plate 74 can be driven by the side push plate 72 to guide in and out of the cartridge body 71, making the refill 9 have a guiding property when entering and exiting the cartridge body 71. It is also not necessary to pick out the inner plate from the slot 711 by hand, and it can prevent the problem that the insertion plate is pulled out excessively from the inside of the cartridge body 71 and the refill 9 scatters. The operation is simple and stable.

[0051] As an improvement of the above technical solution, the sliding guide assembly 73 includes a second limit block 731, a rotating column 732 and a bracket 733. The second limit block 731 is fixed on the side wall of the cartridge body 71. There are two second limit blocks 731 arranged in parallel. One end of the two second limit blocks 731 close to the opening of the cartridge body 71 is connected with a fixed block, and a rotating column 732 is rotatably connected between the two fixed blocks. The side push plate 72 is slidably inserted between the two second limit blocks 731. The inner wall of the side push plate 72 fits against the side wall of the cartridge body 71, and the outer wall of the side push plate 72 rolls and fits against the outer wall of the rotating column 732.

[0052] By pushing the side push plate 72 on the outer wall of the cartridge body 71 to slide along the two second limit blocks 731 and making the rotating column 732 roll and fit against the outer wall of the side push plate 72, the friction force received when the side push plate 72 slides in a guiding manner is reduced. Thus, not only the guiding property of the movement of the side push plate 72 is ensured, but also the flexibility of the movement of the side push plate 72 is ensured.

[0053] As an improvement of the above technical solution, the side push plate 72 includes an inclined plate 721 and a side plate 722. The side plate 722 is slidably inserted between two second limit blocks 731. One end of the side plate 722 is connected to the side wall of the outer plate, and the other end is obliquely connected to the inclined plate 721 at an obtuse angle. The inner side of the obtuse angle between the inclined plate 721 and the side plate 722 is an arc concave surface structure. The angle formed between the inclined plate 721 and the side wall of the box body 71 is an acute angle;

[0054] By holding the inclined plate 721 and pushing the side plate 722 to slide in a guiding manner, the clamping plate 74 is extended from the inside of the box body 71. When the clamping plate 74 just extends from the inside of the box body 71, the arc concave surface between the inclined plate 721 and the side plate 722 reaches the position of the rotating column 732 at this time. Then, the inclined plate 721 is pressed against the side wall of the box body 71, so that the acute angle between the inclined plate 721 and the box body 71 is reduced, thereby causing the side plate 722 to flip outward of the box body 71 and driving the inner plate made of spring sheet to flip, releasing the clamped refill 9, making it more convenient to take out the refill 9.

[0055] As an improvement of the above technical solution, the guide post 81 is provided with an inclined surface near the inner wall of the centrifugal barrel 8. The inclined surface of the guide post 81 and the inner wall of the centrifugal barrel 8 form an acute angle groove structure. The inclined plate 721 is inserted into the acute angle groove, and the inclined plate 721 is attached to the inclined surface of the guide post 81;

[0056] By inserting the inclined plate 721 between the acute angle grooves formed by the guide post 81 and the inner wall of the centrifugal barrel 8 to limit the movement of the inclined plate 721, it can further ensure the stability of the refill 9 being clamped and stored inside the box body 71 when the refill 9 is centrifuged.

[0057] The working principle and usage process of the present invention:

[0058] First, press Figure 5 and Figure 6 to load the refill 9 into the storage mechanism 7 in a separated state. By stacking multiple refills 9 together and inserting them between the two clamping plates 74, the inner plate of the clamping plate 74 is made of a spring plate. The refill 9 is clamped by the elasticity of the inner plate, and the tip of the refill 9 is attached to the backing plate 75. The top and bottom of the stacked refills 9 are temporarily pressed by both hands to limit the movement of the refill 9. Then, the two clamping plates 74 are pushed so that the refill 9 and the backing plate 75 completely enter the box body 71 until the outer plate of the clamping plate 74 is inserted into the slot 711 on the box body 71, completing the loading of the refill 9 into the storage mechanism 7. Similarly, multiple storage mechanisms 7 are filled with refills 9;

[0059] Then, press Figures 1-4 and Figure 8Place multiple storage mechanisms 7 filled with refill cartridges 9 on the support ring 3. Start the pneumatic rod 6, and use the pneumatic rod 6 to push the bucket lid 4 upward. The bucket lid 4 pushes the blocking block 51 upward, causing the blocking block 51 to drive the support column 52 to move upward. The two support plates 53 on the support column 52 rise inside the centrifugal bucket 8. During the rising process, the card slots 531 cooperate with the outer wall of the guide post 81 to slide, so that the support plate 53 is guided upward until the top surface of the lowermost support plate 53 is flush with the top surfaces of the retaining ring 21, the support ring 3, and the centrifugal bucket 8. The spacing distance between the two support plates 53 is less than the length of the guide post 81. At this time, the guide post 81 is always inserted inside the card slot 531 of the lowermost support plate 53. Then, push the box body 71 of a group of storage mechanisms 7, so that the box body 71 is pushed from the support ring 3 onto the top surface of the support plate 53, and the opening side of the box body 71 is inserted into the inside of the first limiting block 532. And at this time, the top surface of the box body 71 is in contact with the bottom surface of the upper support plate 53. Then rotate the support plate 53, and insert the other storage mechanisms 7 one by one into the first limiting blocks 532 distributed in the circumferential direction;

[0060] Then start the pneumatic rod 6 to pull the bucket lid 4 downward. The exhaust rack 5 descends, and the lowermost support plate 53 drives multiple storage mechanisms 7 filled with refill cartridges 9 to move downward and enter the inside of the centrifugal bucket 8. During the entry process, the inclined plate 721 of the side push plate 72 in each storage mechanism 7 is inserted into the acute angle groove formed by the inclined surface of the corresponding guide post 81 and the inner wall of the centrifugal bucket 8, and the inclined block is in contact with and slides along the inclined surface of the guide post 81, so that each storage mechanism 7 is inserted between the two guide posts 81, restricting the position of the inclined plate 721, so that the refill cartridges 9 can be stably stored inside the storage mechanism 7;

[0061] As the exhaust rack 5 descends, the upper support plate 53 descends until its top surface is flush with the top surfaces of the retaining ring 21, the support ring 3, and the centrifugal bucket 8. In the same way as the above steps, insert the other storage mechanisms 7 filled with refill cartridges 9 on the support plate 53, and use the bucket lid 4 to restrict the top surface of the storage mechanism 7. Then start the pneumatic rod 6 to pull the bucket lid 4 downward, so that the entire exhaust rack 5 descends, and the upper support plate 53 drives the placed storage mechanisms 7 to continue to move downward and enter the inside of the centrifugal bucket 8 until the bucket lid 4 is in contact with the top surface of the support ring 3, closing the top surface of the outer bucket 2;

[0062] Then start the motor 11, so that the first transmission wheel 13 drives the second transmission wheel 15 to rotate inside the base 12 by using the transmission belt 14. The second transmission wheel 15 drives the centrifugal bucket 8 to rotate inside the outer bucket 2 through the rotating shaft 16, causing the refill cartridges 9 inside the storage mechanism 7 to perform circular motion, and under the action of centrifugal force, the air bubbles are discharged from the inside of the core tube;

[0063] Finally, after completing the centrifugal exhaust, the entire exhaust rack 5 is lifted, the storage mechanism 7 is removed from the support plate 53, and then the refill 9 of each storage mechanism 7 is taken out. By positioning the box body 71 above the conveyor belt for inspection, and pushing the inclined plate 721 in the opening direction of the box body 71, the side plate 722 slides along the second limit block 731, and the clamping plate 74 is drawn out from the inside of the box body 71, so that the backing plate 75 pushes out the refill 9 until the connection position of the inclined plate 721 and the side plate 722 reaches the rotating column 732. At this time, the cushion block is flush with the end face of the box body 71, and the refill 9 completely extends out of the box body 71. Then, press the inclined plate 721 towards the side wall of the box body 71, so that the side plate 722 flips and drives the elastic inner plate to flip and open towards both sides of the stacked refills 9, so that the refills 9 clamped between the two clamping plates 74 are completely released and fall down onto the conveyor belt for inspection. The detection equipment is used to detect whether the air bubbles in each refill 9 are completely removed.
