Description

Technical Field

[0001] This utility model relates to the field of pencil processing technology, specifically to a pencil lead processing mechanism. Background Technology

[0002] The pencil lead bonding mechanism is a key device used in pencil manufacturing to bond the pencil lead to the wood. The bonding mechanism mainly works by evenly applying glue to the contact surface between the pencil lead and the wood, and then using a certain pressure and bonding device to firmly fix the pencil lead into the wooden pencil barrel.

[0003] The existing pencil lead processing mechanism still has the following problems when in use: uneven glue application, resulting in poor adhesion between the pencil lead and the pencil barrel in some areas, which can easily lead to loosening or breakage during use, affecting the quality and service life of the pencil. In addition, the lead processing efficiency is low. In large-scale production, the lead processing speed cannot keep up with other production stages, resulting in low production efficiency and increased production costs. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Please see Figures 1-4In this embodiment of the utility model, a pencil core processing mechanism includes a transmission mechanism 1. The top of the transmission mechanism 1 is provided with a first glue application mechanism 3 and a second glue application mechanism 4. One end of the transmission mechanism 1 is provided with a pressing mechanism 2. The transmission mechanism 1 includes a transmission box 11. A transmission groove 13 is opened in the middle of the top of the transmission box 11. A belt conveyor mechanism is provided in the transmission groove 13. The first glue application mechanism 3 includes two first electric brackets 31 fixedly installed in a front-to-back symmetrical manner on the other side of the top of the transmission box 11. Multiple first glue application rollers 32 are arranged horizontally and equidistantly between the two first electric brackets 31. A first glue supply machine 33 is provided above the multiple first glue application rollers 32. The overall glue application structure design is optimized. An independent wood board glue application mechanism and a pencil core glue application mechanism are adopted, both of which are set on the transmission mechanism 1. The wood board can be glued first. The glued pencil core is placed in the circular groove of the wood board, ensuring that there is glue contact between the circular groove of the wood board and the pencil core, thus avoiding the pencil core and the pen barrel being not firmly bonded.

[0024] The second glue application mechanism 4 includes a connecting frame 41 fixedly connected to the middle of the front and rear ends of the transmission box 11. A metering electric feeder 42 is fixedly installed between the two connecting frames 41. A discharge trough 43 is provided at the bottom of the metering electric feeder 42. A positioner 47 is fixedly installed at the other end of the metering electric feeder 42. A second electric support 44 is fixedly installed at the bottom of the metering electric feeder 42 and at both ends of the discharge trough 43. A second glue application roller 45 is provided in the two second electric supports 44 and at both ends of the discharge trough 43. The overall workflow of the glue core mechanism is optimized. The positioner 47 is provided so that when the wood board is transported by the conveyor belt 15, the glued pen core is put into the multiple circular slots for assembling pen cores that are equidistantly opened on the wood board by the metering electric feeder 42. This reduces manual intervention and waiting time, making the entire glue core process smoother and more efficient.

[0025] A first support 12 is fixedly connected to each of the four corners at the bottom of the transmission box 11. The belt conveyor mechanism includes two pulleys 14 arranged symmetrically inside the transmission groove 13. The same transmission belt 15 is sleeved on the outside of the two pulleys 14. The two pulleys 14 can rotate, driving the transmission belt 15 on their outside to move, realizing the transmission of the wooden board for pencil processing and production on it. Multiple circular grooves for assembling pencil leads are equally spaced on the wooden board.

[0026] The pressing mechanism 2 includes a limiting bracket 21 fixedly connected to one end of the transmission box 11. The bottom end of the limiting bracket 21 is fixedly connected to the front and rear sides of the second support 26. The top end of the limiting bracket 21 is provided with a limiting assembly groove 22. The front and rear ends of the limiting bracket 21 are each fixedly connected to a fixed frame 23. The same press 24 is fixedly installed between the two fixed frames 23. The movable end of the hydraulic movable shaft at the bottom of the press 24 is fixedly connected to a pressing plate 25. The press 24 can put the wooden board with the pen core in the circular groove into the limiting assembly groove 22, and place another wooden board without the pen core but with glue on it. The press 24 drives the pressing plate 25 to press the two wooden boards to press and fix the pen core inside, ensuring that the glue can fully exert its adhesive effect. At this time, the wooden board can be cut into a pen barrel, thus completing the glue core processing of the pencil.

[0027] The first glue feeder 33 has a material tank 34 fixedly connected to its top feed end. The bottom end of the first glue feeder 33 is provided with multiple glue outlets that match the first glue coating roller 32, which can supply glue to the first glue coating roller 32. The front end of the second electric bracket 44 is fixedly installed with a second glue feeder 46. The top end of the second glue feeder 46 is provided with a feed port that can be connected to a glue supply pipe. The rear end of the second glue feeder 46 is provided with a glue outlet that supplies glue to the two second glue coating rollers 45.

[0028] The working principle of this utility model is as follows: Two pulleys 14 can rotate, driving the outer conveyor belt 15 to move, realizing the transmission of the wooden board for pencil processing. The wooden board has multiple circular grooves for assembling pencil leads at equal intervals. It can be uniformly glued to its top surface by multiple first glue-applying rollers 32 and continue to be transmitted. The whole is equipped with a positioner 47, which can intermittently feed the wood board to multiple transmitted wood boards via a metering electric feeder 42 when the wood board is transmitted by the conveyor belt 15. That is, after a pencil lead is put into the circular groove of one wood board, no feeding is done to the next one, until the next one is put into the next one. During the aforementioned feeding process, the pencil lead is discharged through the discharge trough 43 of the metering electric feeder 42. During discharge, it can be evenly coated with glue by the second glue roller 45. The pencil lead in the circular groove is already coated with glue. The wooden board with the pencil lead in the circular groove can be placed into the limiting assembly groove 22, and another wooden board without a pencil lead but coated with glue can be placed on it. The pressing plate 25 driven by the press 24 presses the two wooden boards together to press and fix the pencil lead inside, ensuring that the glue can fully exert its adhesive effect. At this time, the wooden board can be cut into a pencil barrel, thus completing the glue core processing of the pencil.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
