It solves the problems of existing pencil lead cutting devices on the market, which lack good performance, quick adjustment of cutting length, and rapid cooling of pencil leads, leading to easy deformation of the pencil leads and making them unsuitable for user operation.
[0004] Based on existing solutions and actual production and processing, the current pen refill ejection structure still has some problems, such as: when the pen refill is placed on the rack, it is easy for it to tilt upwards and shift during cutting, affecting the quality; moreover, the debris generated during cutting is directly scattered, requiring workers to clean up the debris, increasing the workload; at the same time, the cutting length is adjusted by pushing the pen refill with the first electric telescopic rod, but the cutting length is unstable, affecting the accuracy. Therefore, we propose a positioning pen refill ejection structure to solve the problems mentioned above. Utility Model Content

[0033] 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.
[0034] Please see Figure 1-6 This utility model provides a technical solution: a positioning pen refill ejection structure, including a worktable 1, a first support plate 2, a second support plate 3, a pushing mechanism 4, a support frame 5, an adjusting component 6, a connecting rod 7, an adjusting frame 8, a gear 9, a second motor 10, a pressure plate 11, a storage platform 12, a first storage box 13, a guide plate 14, a connecting port 15, a second storage box 16, a spring 17, and a limiting plate 18.
[0035] Example: Existing pen refills placed on a shelf are prone to tilting upwards and shifting during cutting, affecting quality. Therefore, this example uses the following technical solution, such as... Figure 1 , Figure 2 and Figure 4 Since the gear 9 is meshed on the sawtooth structure of the adjustment frame 8, the pressure plate 11 is in a lifting structure on the upper side of the workbench 1 through the gear 9 and the adjustment frame 8, and the width of the pressure plate 11 is equal to the width of the first bearing plate 2.
[0036] Therefore, multiple pen refills are placed sequentially in the arc-shaped grooves at the upper ends of the first support plate 2 and the second support plate 3 for simple positioning, so that the second motor 10 can work to drive the gear 9 to rotate. When the gear 9 rotates, it meshes with the sawtooth structure on the front and rear inner walls of the adjustment frame 8.
[0037] The connecting rods 7, which are symmetrically arranged at the front and rear, drive the adjusting frame 8 to descend stably, so that the adjusting frame 8 drives the pressure plate 11 to descend, so that the lower end of the pressure plate 11 fits against the upper end of the pen refill, thereby facilitating positioning and preventing deviation during cutting.
[0038] The existing method adjusts the cutting length by pushing the pen refill with a first electric telescopic rod, but the cutting length is unstable, affecting accuracy. Therefore, this embodiment adopts the following technical solution, such as... Figure 1 and Figure 5 Since the top of the adjusting plate 603 is slidably connected to the inside of the long groove 604, the adjusting plate 603 has a sliding structure on the lower side of the support frame 5 through the threaded rod 601 and the long groove 604.
[0039] Therefore, when the first motor 602 is working, it drives the threaded rod 601 to rotate at the lower left end of the support frame 5, so that the upper end of the adjusting plate 603 slides left and right inside the long groove 604, adjusting the distance between the adjusting plate 603 and the left end of the worktable 1, so that the pushing mechanism 4 pushes the pen refill to the left until the left end of the pen refill touches the lower right end of the adjusting plate 603, thus making it easy to adjust the cutting length.
[0040] Existing cutting methods generate debris that simply scatters, requiring workers to clean it up, increasing workload. Therefore, this embodiment addresses this issue by implementing the following technical solution: Figure 1 , Figure 3 and Figure 6 Since springs 17 are fixedly connected at equal intervals on the left wall of the shelf 12, the width of the first storage box 13 is greater than the width of the guide plate 14, and the connection port 15 is connected to the first storage box 13 through the guide plate 14.
[0041] Therefore, the first storage box 13 is placed inside the right end of the shelf 12, so that the right wall of the first storage box 13 abuts against the right wall of the shelf 12. The second storage box 16 is placed inside the left end of the shelf 12, so that the right wall of the second storage box 16 fits against the left wall of the first storage box 13. The springs 17, which are set at equal intervals, drive the limiting plate 18 to move to the right.
[0042] Until the limiting plate 18 abuts against the second storage box 16, it limits the position of the first storage box 13 and the second storage box 16 on the shelf 12. During cutting, the scraps fall into the connecting port 15. The scraps in the connecting port 15 slide into the interior of the first storage box 13 through the inclined direction of the guide plate 14, which facilitates the collection of pen refills and scraps. All the electrical components mentioned above are existing technologies and will not be described in detail here.
[0043] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.
[0044] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
