Description

Technical Field

[0001] This utility model is a device for quantitative dispensing of colored lead cores, belonging to the technical field of stationery and sports products. Background Technology

[0002] Colored lead, the core component of colored pencils, determines the color and writing effect of the pencil. Primarily used for drawing and writing, colored lead is a composite material made from a mixture of various materials, the main components of which include graphite, clay, and pigments. The manufacturing process of colored lead involves first weighing and batching the raw materials, then mixing and stirring them, followed by kneading the mixture. After kneading, the mixture is ground, extruded, dried, sintered, and then impregnated with oil to obtain the colored lead. A quantitative batching device is required for weighing and batching the raw materials.

[0003] The existing batching device can only weigh colored lead core raw materials once. In actual use, after weighing multiple sets of raw materials, the raw materials in the batching device need to be taken out and weighed again. This process needs to be repeated many times to complete the weighing of multiple colored lead core raw materials, which is quite cumbersome. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a quantitative dispensing device for colored lead cores.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A quantitative dispensing device for colored lead cores includes a dispensing box. Several dispensing cylinders are fixed to the top of the dispensing box; the number of dispensing cylinders can be increased or decreased depending on the required dispensing type. A feed pipe extends from the top of each dispensing cylinder to the outside of the dispensing box, and a threaded cap is threaded to the top of the feed pipe. A discharge pipe extends from the bottom of each dispensing cylinder to the inside of the dispensing box, and a solenoid valve is installed on the discharge pipe. A base plate is fixed to the inner bottom of the dispensing box, and a rotating mechanism is installed on the top of the base plate. A receiving tray is connected to the output end of the rotating mechanism, and several dispensing frames are fixed to the top of the receiving tray. The tops of the dispensing frames correspond to the discharge pipes of the feed pipe.

[0007] Furthermore, the rotating mechanism includes a motor and a support column fixed to the top of the base plate. The output end of the motor is connected to a drive disk. An arc-shaped disk and a lever are fixed to the top of the drive disk. The arc-shaped disk is located at the top center of the drive disk, and the lever is located on one side of the top of the drive disk. A turntable is rotatably connected to the top of the support column. The outer surface of the turntable is evenly provided with six arc surfaces. The arc surfaces cooperate with the outer surface of the arc-shaped disk. A sliding groove is provided between two adjacent arc surfaces. The sliding groove cooperates with the lever.

[0008] Furthermore, a support rod is fixed to the top of the turntable, and the top end of the support rod is fixedly connected to the receiving tray. The top of the receiving tray is divided into six receiving areas, and several weighing devices are fixed to the top of each receiving area. The top of each weighing device is provided with a dispensing frame. The several dispensing frames in the receiving area correspond to the feeding pipes of several dispensing cylinders. The number of weighing devices corresponds to the number of dispensing frames, and the number of weighing devices corresponds to the number of dispensing cylinders. The number of weighing devices is adjusted according to the number of dispensing cylinders.

[0009] Furthermore, the top of the receiving tray is provided with several clamping components that cooperate with the dispensing frame. The clamping components include fixed plates fixed to both sides of the weighing device, T-shaped rods slidably connected to the fixed plates, through holes that cooperate with the T-shaped rods on the fixed plates, limit plates fixed on the T-shaped rods, springs connected between the limit plates and the fixed plates, and clamping members provided at the ends of the T-shaped rods away from the springs. Two of the clamping members cooperate with the sides of the dispensing frame.

[0010] Furthermore, the front of the mixing box is provided with an opening, and the top of the outer surface of the feed pipe is provided with an external thread that mates with the threaded cap.

[0011] Furthermore, the feeding pipe is equipped with a solenoid valve, the batching box is equipped with a controller, and the solenoid valve and the motor are both electrically connected to the controller.

[0012] The beneficial effects of this utility model are:

[0013] By using a rotating mechanism, once the raw materials in several batching cylinders are weighed in the batching frames within the receiving area, the raw material preparation for one colored lead core is complete. The rotating mechanism then rotates several batching frames in the next receiving area to the bottom of the batching cylinder. At this point, the raw materials in the batching cylinders can be introduced into the batching frames for weighing. This completes the preparation of the raw materials for another colored lead core. Then, the batching frames in the next receiving area are rotated to the bottom of the batching cylinder again. This process is repeated to weigh several colored lead cores. This avoids the need to remove the raw materials from the batching frames after weighing one colored lead core, place the batching frames on top of the weighing device, and introduce the raw materials again for weighing, thus saving operational steps and improving work efficiency.

[0014] With the clamping component in place, the material box located on top of the weighing device can be clamped and fixed, making it simple and convenient to use. Attached Figure Description

Detailed Implementation

[0024] 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.

[0025] Please see Figure 1-7 This utility model provides a technical solution for a quantitative dispensing device for colored lead cores, including a dispensing box 1. Several dispensing cylinders 2 are fixed to the top of the dispensing box 1. A feeding pipe 3 is provided through the top of the dispensing cylinders 2 to the outside of the dispensing box 1. A threaded cap 15 is threadedly connected to the top of the feeding pipe 3. A discharge pipe 16 is provided through the bottom of the dispensing cylinders 2 to the inside of the dispensing box 1. A solenoid valve is provided on the discharge pipe 16. A base plate 4 is fixed to the inner bottom of the dispensing box 1. A rotating mechanism is provided on the top of the base plate 4. A receiving tray 12 is connected to the output end of the rotating mechanism. Several dispensing frames 14 are fixed to the top of the receiving tray 12. The top of the dispensing frames 14 corresponds to the discharge pipe of the feeding pipe 3.

[0026] See Figure 2 , Figure 4 and Figure 5The rotating mechanism includes a motor and a support column fixed to the top of the base plate 4. The output end of the motor is connected to a drive disk 5. An arc-shaped disk 6 and a lever 7 are fixed to the top of the drive disk 5. The arc-shaped disk 6 is located in the middle of the top of the drive disk 5, and the lever 7 is located on one side of the top of the drive disk 5. A turntable 8 is rotatably connected to the top of the support column. The outer surface of the turntable 8 is evenly provided with six arc surfaces 9. The arc surfaces 9 cooperate with the outer surface of the arc-shaped disk 6. A sliding groove 10 is opened between two adjacent arc surfaces 9. The sliding groove 10 cooperates with the lever 7. A support rod 11 is fixed to the top of the turntable 8. The top end of the support rod 11 is fixedly connected to the receiving disk 12. The top of the receiving disk 12 is divided into six receiving areas 17. Several weighing devices 13 are fixed to the top of the receiving areas 17. The dispensing frame 14 is provided on the top of the weighing devices 13. Several dispensing frames are located in the receiving areas 17. The frame 14 corresponds to the feeding pipe 16 of several feeding cylinders 2. Through the setting of the rotating mechanism, after the raw materials in several feeding cylinders 2 are weighed in the feeding frame 14 in the receiving area 17, the raw materials required for one colored lead core are configured. The rotating mechanism will drive several feeding frames 14 in the next receiving area 17 to rotate to the bottom of the feeding cylinder 2. At this time, the raw materials in the feeding cylinder 2 can be introduced into the feeding frame 14 for weighing. At this time, the raw materials required for another colored lead core are configured. Then, the feeding frame 14 in the next receiving area 17 is rotated to rotate to the bottom of the feeding cylinder 2 again. This process is repeated to complete the weighing of several colored lead core raw materials. This avoids the need to take out the raw materials in the feeding frame 14 after weighing the raw materials required for one colored lead core, and then place the feeding frame 14 on the top of the weighing device 13 and introduce the raw materials again for weighing. This saves certain operation steps and improves work efficiency.

[0027] See Figure 6 The top of the receiving tray 12 is provided with several clamping assemblies that cooperate with the dispensing frame 14. The clamping assembly includes a fixing plate 18 fixed on both sides of the weighing device 13. A T-shaped rod 19 is slidably connected to the fixing plate 18. The fixing plate 18 has a through hole that cooperates with the T-shaped rod 19. A limit plate is fixed on the T-shaped rod 19. A spring 21 is connected between the limit plate and the fixing plate 18. A clamping member 20 is provided at the end of the T-shaped rod 19 away from the spring 21. Two clamping members 20 cooperate with the side of the dispensing frame 14. Through the setting of the clamping assembly, the clamping assembly can clamp and fix the dispensing frame 14 located on the top of the weighing device 13, which is simple and convenient to use.

[0028] See Figure 1 and Figure 3The mixing box 1 has an opening on the front, the top of the outer surface of the feed pipe 3 has an external thread that matches the threaded cover 15, the feed pipe 16 is equipped with a solenoid valve, the mixing box 1 is equipped with a controller, the solenoid valve 16 and the motor are electrically connected to the controller, the threaded cover 15 and the external thread can seal the top of the feed pipe 3, making it relatively simple to use.

[0029] In use, when it is necessary to weigh and batch various groups of raw materials, multiple groups of raw materials are placed into several batching cylinders 2. Several batching frames 14 on the receiving area 17 correspond to the discharge pipes 16 at the bottom of several batching cylinders 2. The controller controls the solenoid valve on the discharge pipe 16 to start, so that the raw materials inside the batching cylinder 2 flow into the batching frame 14 through the discharge pipe 16. The value on the weighing device 13 is observed. When the required weight is reached, the controller controls the solenoid valve to close. Then, the motor is started, and the motor drives the drive disc 5 to rotate. The drive disc 5 drives the arc disc 6 and the lever 7 to rotate. As the drive disc 5 rotates, the drive disc 5 drives the lever 7 to rotate into the slide groove 10 on the turntable 8. As the drive disc 5 continues to rotate, the lever 7 will squeeze the inner wall of the slide groove 10 when rotating, thereby driving the slide groove 10 to rotate. The slide groove 10 drives the turntable 8 and the support The lever 11 and the receiving tray 12 rotate, and the receiving tray 12 drives the weighing device 13 and the feeding frame 14 at the top to rotate. When the lever 7 leaves the slide 10, the arc surface 9 of the turntable 8 contacts the outer surface of the arc-shaped disk 6. At this time, the turntable 8 does not move. At this time, the turntable 8 drives several feeding frames 14 on the next set of receiving areas 17 to rotate to the bottom of several feeding cylinders 2. At this time, the discharge pipe 16 at the bottom of the feeding cylinder 2 corresponds to the top of the feeding frame 14. At this time, the controller starts the solenoid valve on the discharge pipe 16 again to introduce the raw material in the feeding cylinder 2 into the feeding frame 14 at the bottom. When the value on the weighing device 13 reaches the required weight, the controller controls the solenoid valve to close again. At the same time, the lever 7 rotates into the next slide 10 again. With the rotation of the lever 7, the slide 10 and the turntable 8 rotate again to repeat the previous operation.

[0030] When the drive disc 5 rotates one revolution, the turntable 8 rotates exactly one-sixth of a revolution. The turntable 8 drives the receiving disc 12 and the next receiving area 17 on top of the receiving disc 12 to rotate one-sixth of a revolution, which in turn drives the next receiving area 17 to rotate to the position corresponding to the bottom of the dispensing cylinder 2. In this way, with the cooperation of the controller and the solenoid valve, six colored lead core raw materials can be weighed and dispensed at once, eliminating the need to remove the dispensed material from the dispensing box 14 after weighing and dispensing one colored lead core raw material and then place the dispensing box 14 on the weighing device. At the top of 13, the raw material is introduced again for weighing. Furthermore, the several batching boxes 14 on each receiving area 17 are just enough to prepare one batch of colored lead core raw material. The six receiving areas 17 can just be enough to prepare six batches of colored lead core raw material. Therefore, this device can prepare six batches of colored lead core raw material at the same time. It is not necessary to take out the weighed raw material after completing one batch of colored lead core raw material preparation, place it inside the batching device, and weigh it again. This saves certain operation steps and improves work efficiency.

[0031] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
