Description

Technical Field

[0001] This utility model belongs to the field of stationery production technology, and specifically refers to a feeding mechanism for a pencil gluing device. Background Technology

[0002] Perforated pencils are pencils with grooves on their circumference to help users position their fingers when holding them, thus stabilizing the grip and maintaining a consistent writing posture, which helps cultivate good writing habits. However, since pencils already have a relatively small cross-section, adding grooves to the circumference further reduces the overall strength of the pencil, making it more prone to lead breakage and resulting in financial losses.

[0003] To address this, the industry has developed designs that apply glue to the surface of pencils, creating easily identifiable raised dots that clearly indicate the gripping position. Clearly, the glue application process on the pencil's circumference requires specialized machinery to ensure quality and efficiency. A crucial step is arranging several pencils neatly on a tray (rack) before glue application, allowing subsequent processes to accurately identify the pencil's orientation (angle) and ensure precise glue application. Currently, this process of arranging pencils on the tray (rack) is still done manually, resulting in high labor intensity and low efficiency. Utility Model Content

[0031] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0032] refer to Figure 1-7 As shown, this utility model discloses a feeding mechanism for a pencil dispensing device, including a material storage device 1 and a material tray conveying device 2;

[0033] The storage device 1 is equipped with a discharge bin 111. The bottom of the discharge bin 111 is provided with a set of first vertical channels 121 arranged side by side, and a set of second vertical channels 122 arranged side by side below the first vertical channels 121. The first vertical channels 121 and the second vertical channels 122 are staggered in the vertical direction, and a gap is reserved between them. A movable plate 13 that can move laterally is provided in the gap. A set of third vertical channels 131 arranged side by side is provided on the movable plate 13. The third vertical channels 131 are aligned with one of the first vertical channels 121 and the second vertical channels 122 as the movable plate 13 moves laterally. The width of the first vertical channels 121, the second vertical channels 122 and the third vertical channels 131 are all sufficient to allow a pencil a to fit with the gap. The height of the third vertical channel 131 is sufficient to allow a pencil a to fit with the gap.

[0034] The tray conveying device 2 is used to convey a tray 3 having a plurality of pencil placement slots 321, so that the pencil placement slots 321 are aligned with or leave from the bottom of the second vertical channel 122, and transferred to other workstations to convey the tray 3 to the next process.

[0035] Through the above scheme, this utility model, by designing a staggered first vertical channel 121 and a second vertical channel 122, and by using a movable plate 13 that works between the first vertical channel 121 and the second vertical channel 122, allows the reciprocating motion of the movable plate 13 to output pencils a in the first vertical channel 121 to the second vertical channel 122 in groups. The pencils a are then transported through the second vertical channel 122 to the lower tray 3 and fall into the pencil placement slot 321, so that the group of pencils a can be output to the subsequent process in a uniform direction. Ultimately, the mechanical system automatically places the pencils a in the tray 3 in a preset direction (or angle), improving the degree of automation and increasing production efficiency and quality.

[0036] The following are specific embodiments of the present invention.

[0037] The number of the first vertical channel 121, the second vertical channel 122, and the third vertical channel 131 are in one-to-one correspondence.

[0038] In this embodiment, the pencil placement groove 321 of the above-mentioned material tray 3 has an approximately V-shaped cross section, that is, the left and right sides of the pencil placement groove 321 have symmetrically arranged inclined surfaces, which are used to guide and position the pencil a when it falls in, and in particular, to ensure that one surface of the pencil a with a triangular or approximately triangular cross section is flat and facing upward after entering the pencil placement groove 321.

[0039] The aforementioned discharge bin 111 is housed within a laterally movable container 11. The storage device 1 has a support 12 fixed relative to the ground or machine platform 10. The aforementioned first vertical channel 121 and second vertical channel 122 are both mounted on the support 12 to maintain their fixed positions. A discharge plate 123 and a first drive device 14 are mounted on the support 12. The discharge plate 123 is equipped with a guide rail 124 for sliding engagement with the movable container 11, and the upper end of the first vertical channel 121 communicates with the discharge plate 123. The first drive device 14 is connected to the movable container 11 via a transmission mechanism. Lateral movement of the movable container 11 causes the pencil a inside the discharge bin 111 to vibrate and fall smoothly into the first vertical channel 121. The first drive device 14 can be a cylinder, a hydraulic cylinder, or a similar device capable of outputting linear reciprocating motion.

[0040] Furthermore, the aforementioned storage device 1 also includes a fixed container 15 docked with the movable container 11; the fixed container 15 is fixed relative to the ground or machine platform 10 and is provided with a feeding hopper 151 communicating with the discharge hopper 111. The feeding hopper 151 is equipped with a discharge conveyor belt 16 for conveying pencils a to the discharge hopper 111, and a feeding conveyor belt 17 for conveying pencils a to the discharge conveyor belt 16. Several push plates 161 are evenly arranged on the circumference of the discharge conveyor belt 16. Thus, workers only need to pour batches of pencils a into the feeding hopper 151, and subsequent work is performed mechanically. In this embodiment, the discharge conveyor belt 16 is arranged along an inclined direction, and the feeding conveyor belt 17 is arranged along a transverse direction; a height-adjustable baffle 152 is provided above the output end of the feeding conveyor belt 17 to adjust the number of pencils a conveyed to the discharge conveyor belt 16, achieving flow control.

[0041] Also see Figure 4 The bottom side of the discharge hopper 111 is provided with a viewing window 112 to facilitate observation of the material storage above the discharge plate 123. In this embodiment, material level sensors 18, such as photoelectric sensors and infrared sensors, are provided above and below the viewing window 112 to detect the material status in the discharge hopper 111 in real time.

[0042] See Figure 5The upper openings of the first vertical channel 121, the second vertical channel 122, and the third vertical channel 131 are all widened by setting chamfers or bevels, so that pencil a can enter the corresponding channel more easily and avoid getting stuck.

[0043] The aforementioned storage device 1 also includes a second drive device 19 that is fixed relative to the ground or machine platform 10 (such as mounted on the aforementioned bracket 12), and the second drive device 19 is connected to the movable plate 13 in a transmission manner. The second drive device 19 can be a cylinder, a hydraulic cylinder, or a similar device capable of outputting linear reciprocating motion.

[0044] See Figure 6-7 This diagram illustrates a portion of the structure of the material tray conveying device 2 of this invention. The material tray conveying device 2 includes a third drive device 21, a movable seat 22, and a feeding belt conveyor 23. One end of the output stroke of the third drive device 21 is located below the second vertical channel 122, while the other end is located outside the lower part of the second vertical channel 122. The movable seat 22 is driven by the third drive device 21 to perform lateral movement, thereby entering or exiting below the second vertical channel 122. The feeding belt conveyor 23 is mounted on the movable seat 22 and is used to carry the material tray 3. Thus, the third drive device 21 can drive the movable seat 22 to move the feeding belt conveyor 23 and the material tray 3 on it into and out of the lower part of the second vertical channel 122, and the feeding belt conveyor 23 can drive the material tray 3 to the next process. In this embodiment, the third drive device 21 is a linear motor or a similar device capable of outputting linear reciprocating motion.

[0045] Furthermore, the aforementioned tray conveying device 2 also includes a pair of tray sensors 24, such as photoelectric sensors and infrared sensors, installed on the movable seat 22 and located at both ends of the feeding belt 23, for real-time detection of whether there are still trays 3 on the feeding belt 23, so as to achieve automation in combination with the program settings of the equipment.

[0046] The aforementioned tray 3 includes a base plate 31 supported by the tray conveying device 2 for conveying, and flanges 32 disposed on both sides of the base plate 31, with the aforementioned pencil placement grooves 321 provided on the flanges 32. Thus, the tray 3 only supports the two ends of the pencil a, while the two ends of the pencil a are suspended, ensuring that the glued area of ​​the pencil a does not contact the tray a after glue dispensing.

[0047] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
