Description

Technical Field

[0001] This utility model relates to the field of pencil processing technology, specifically to a multi-sided printing device for pencil barrels. Background Technology

[0002] Pencil manufacturing involves combining wood and graphite cores. First, suitable wood, such as pine or birch, is selected, cut into cylindrical shapes, and grooved. Next, graphite cores are made by mixing graphite powder with adhesive and water to form long strips. The graphite cores are then fixed into the grooves in the wooden shaft. The pencil surface is coated with a finishing varnish, and then it is cut, sanded, printed, and packaged. The entire process requires approximately 20 to 50 steps, including wood processing, core manufacturing, pencil shaft assembly, and exterior decoration, ultimately resulting in a smooth, branded finished pencil.

[0003] Currently, when processing pencils, printing devices are used to print on the surface of the pencil, engraving text and other information onto the pencil shaft. When using a printing device to print on the pencil shaft, it is usually placed on a conveyor belt and transported to the bottom of the printing end before printing. When multiple sides of the pencil shaft need to be printed, the pencil needs to be transported and printed multiple times, resulting in low printing efficiency and affecting the processing efficiency of pencils.

However, when multi-sided printing of pencil barrels is required, the pencil needs to be transported and printed multiple times, resulting in low printing efficiency and affecting the processing efficiency of pencils.

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.

[0023] Please see Figure 1-4 This utility model provides a new technical solution: a multi-sided printing device for pencil barrels for pencil processing, including a conveyor belt 1, an mounting plate 2 fixedly installed on the upper surface of the conveyor belt 1, a printing component 3 fixedly installed on the inner wall of the mounting plate 2, and a drying box 4 fixedly installed at the rear end of the upper surface of the conveyor belt 1.

[0024] The auxiliary mechanism is set on the drying oven 4. The auxiliary mechanism includes a mounting box 5 and a rotating rod 6. Mounting holes 7 are opened on the left and right inner walls of the mounting plate 2. The two mounting boxes 5 are slidably installed inside the two mounting holes 7 respectively. The two rotating rods 6 are rotatably installed on the adjacent surfaces of the two mounting boxes 5 respectively. The far ends of the two rotating rods 6 slide through into the interior of the two mounting boxes 5 respectively. Clamping plates 8 are fixedly installed on the adjacent ends of the two rotating rods 6.

[0025] Furthermore, the auxiliary mechanism also includes multiple placement brackets 9, all of which are fixedly installed on the outer surface of the conveyor belt 1.

[0026] Furthermore, by using two second electric push rods 13 to drive two rotating rods 6 closer together, the two clamping plates 8 clamp the pencil barrel, and then the two first electric push rods 11 drive the pencil barrel upward, so that the two motors 12 can rotate the pencil barrel. After being placed back into the placement bracket 9, the pencil barrel can be printed on multiple sides, which improves the processing efficiency of the device for pencil barrels, thereby improving the production efficiency of pencil barrels.

[0027] Furthermore, mounting grooves 10 are provided on both the left and right surfaces of the mounting plate 2. The lower ends of the two mounting grooves 10 are respectively connected to the interior of the two mounting holes 7. A first electric push rod 11 is fixedly installed on the upper inner wall of the two mounting grooves 10. The two first electric push rods 11 are respectively fixedly connected to the two mounting boxes 5.

[0028] Furthermore, motors 12 are slidably mounted on the inner walls of both mounting boxes 5. The output ends of the two motors 12 are fixedly connected to the two rotating rods 6 respectively. Second electric push rods 13 are fixedly mounted on the distant surfaces of the two mounting boxes 5. The proximal ends of the two second electric push rods 13 penetrate into the interior of the two mounting boxes 5 respectively. The two second electric push rods 13 are fixedly connected to the two motors 12 respectively.

[0029] Furthermore, rubber pads 14 are fixedly installed on the adjacent surfaces of the two clamping plates 8.

[0030] Furthermore, an electric heating plate 15 is fixedly installed on the rear inner wall of the drying oven 4, and a discharge pipe 16 is fixedly installed on the upper end of the rear surface of the drying oven 4, with the front end of the discharge pipe 16 communicating with the interior of the drying oven 4.

[0031] Furthermore, when using this device, the pencil barrels to be printed can be placed on multiple placement brackets 9, and the pencil barrels can be sent to the lower end of the mounting plate 2. When the pencil barrels reach the lower end of the mounting plate 2, the printing electric push rod on the printing assembly 3 can be activated. The printing electric push rod drives the heat transfer plate fixedly connected to its telescopic end to move downward, printing on the surface of the pencil barrel. When multiple sides need to be printed, two second electric push rods 13 can be activated, causing the two second electric push rods 13 to drive the motors 12 fixedly connected to their telescopic ends to move inside the corresponding mounting boxes 5. The two motors 12 drive the rotating rods 6 fixedly connected to their output ends to move closer to each other, so that the clamping plates 8 on the two rotating rods 6 clamp the pencil barrels placed on the placement brackets 9. The two first electric push rods 11 drive the mounting boxes 5 to move upward. This causes the pencils held on the two clamping plates 8 on the two mounting boxes 5 to move upwards, and the pencils held between the two clamping plates 8 to move upwards and leave the placement bracket 9. Then, the two motors 12 can be started, causing the rotating rods 6 fixedly connected to their output ends to rotate with the clamping plates 8, thereby rotating the pencil barrel between the two clamping plates 8. After rotation, the pencil barrel is placed back into the placement bracket 9. The conveyor belt 1 drives the placement bracket 9 forward a certain distance, and then the printing electric push rod drives the heat transfer plate to print on the other surfaces of the pencil barrel. This device can conveniently print on multiple sides of the pencil barrel. After printing, the pencil barrel enters the drying chamber 4, and the interior of the drying chamber 4 is heated and dried by the electric heating plate 15 to dry the pencil barrel inside the drying chamber 4.
