Description

Technical Field

[0001] This utility model relates to the field of colored pen refill processing technology, and in particular to an energy-saving extrusion device for high-saturation colored pen refills. Background Technology

[0002] To improve the saturation of colored pencil leads, in addition to using purer pigment powder, it is also necessary to ensure the dispersion of the pigment powder in the raw material mixture.

[0003] In the prior art, invention patent application No. 2017103522609 discloses a water-resistant colored pencil lead and its production process. The raw materials are stirred and then put into a three-roll mill for extrusion. After extrusion, the raw materials are in the form of flakes. After stirring and crushing, the raw materials are in the form of coin-sized flakes. The extrusion of the three-roll mill improves the dispersion effect of the pigment powder. However, in the actual production process, the solid blocks formed after the raw materials are mixed and stirred have poor fluidity and are prone to clogging in the hopper of the three-roll mill, affecting the smoothness of material feeding, thereby reducing the production efficiency of colored pencil leads and increasing energy consumption.

[0004] In addition, the gap between the rear roller and the middle roller in the three-roll mill is small. Some solid lumps enter the space above the gap between the rear roller and the middle roller and float above the gap, which affects the extrusion efficiency of the raw materials by the rear roller and the middle roller and further increases energy consumption, so improvements are needed. Utility Model Content

[0005] The purpose of this invention is to provide an energy-saving extrusion device for high-saturation colored pencil refills, avoiding the clogging problem of colored pencil refill raw materials and improving extrusion production efficiency.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] An energy-saving extrusion device for high-saturation colored pencil refills includes: a three-roll mill, a hopper, a pressing block, and a pressing block driving mechanism. The three-roll mill has a first roller, a second roller, and a third roller arranged parallel to each other from back to front. A support is provided at the top of the three-roll mill, and the hopper is disposed within the support. A discharge port is located at the bottom of the hopper above the gap between the first and second rollers. The pressing block is vertically and flexibly disposed within the discharge port. The pressing block driving mechanism includes a push rod, a motor, a turntable, and a drive rod. The push rod is disposed at the top of the pressing block and extends upwards above the hopper. A floating seat is provided at the top of the push rod. The motor is horizontally disposed at the top of the hopper. The turntable is vertically disposed on the motor's shaft and located on one side of the floating seat. A guide groove is horizontally disposed in the floating seat. The drive rod is eccentrically disposed on the turntable and extends into the guide groove.

[0008] The drive rod is equipped with a bearing located in the guide groove.

[0009] The hopper is equipped with a guide plate that extends obliquely downward to the discharge port.

[0010] Wherein, the length of the pressing block along the axial direction of the first roller is less than the length of the discharge port along the axial direction of the first roller.

[0011] The hopper is equipped with a guide sleeve corresponding to the push rod.

[0012] The three-roll mill has a scraper in front of it that contacts the third roller.

[0013] The three-roll mill has pin seats on both sides of its front end, and the pin seats are rotatably equipped with support rods that are connected to the scraper.

[0014] The front end of the three-roll mill is provided with a tension spring located above the pin seat and connected to the support rod.

[0015] The beneficial effects of this invention are as follows: An energy-saving extrusion device for high-saturation colored pencil refills, by raising and lowering the pressure block in the feeding port, avoids clogging of the colored pencil refill raw material, ensuring smooth feeding and extrusion dispersion. This ensures the dispersion effect and high saturation of the pigment powder in the raw material. Furthermore, the descent of the pressure block presses down the raw material located above the gap between the first and second rollers, preventing the raw material from floating above and failing to enter the gap. This ensures the efficiency of extrusion production, reduces idling, and thus lowers energy consumption, making it more energy-efficient. Attached Figure Description

[0020] The following is combined Figures 1-4 The technical solution of this utility model will be further illustrated through specific embodiments.

[0021] like Figure 1 and Figure 2The energy-saving extrusion device for high-saturation colored pencil refills shown includes: a three-roll mill 1, a hopper 2, a pressing block 15, and a pressing block drive mechanism. The three-roll mill 1 has a first roller 11, a second roller 12, and a third roller 13 arranged in parallel from back to front. The first roller 11 rotates in opposite directions to the second roller 12, and the second roller 12 rotates in opposite directions to the third roller 13, performing multiple extrusions and dispersions of the colored pencil refill raw material, thereby improving the dispersion effect of pigment powder in the raw material and thus improving the high saturation of the colored pencil refill.

[0022] A support 3 is provided on the top of the three-roll mill 1, and the hopper 2 is placed in the support 3 and can be fixed with screws to improve the stability of the hopper 2. The top of the hopper 2 is open, making it convenient to pour the colored pencil refill material into the hopper 2.

[0023] like Figure 3 As shown, the bottom of the hopper 2 is provided with a discharge port 16 located above the gap between the first roller 11 and the second roller 12. In this embodiment, a guide plate 17 extending obliquely downward to the discharge port 16 is provided in the hopper 2, so that the colored pencil refill material in the hopper 2 can flow down to the discharge port 16. The colored pencil refill material in the hopper 2 enters downward through the discharge port 16 into the gap between the first roller 11 and the second roller 12, where it undergoes a first extrusion and dispersion through the cooperation of the first roller 11 and the second roller 12. Then, it enters the gap between the second roller 12 and the third roller 13 for a second extrusion and dispersion, forming a sheet for output.

[0024] like Figure 1 As shown, a scraper 14 is obliquely placed in front of the three-roll mill 1, which contacts the third roller 13. The scraper 14 cleans the sheet off the third roller 13, and the sheet is output downward along the top surface of the scraper 14, which facilitates subsequent crushing.

[0025] In this embodiment, pin seats 19 are provided on both sides of the front end of the three-roll mill 1. A support rod 18, connected to the scraper 14, is rotatably mounted in each pin seat 19. The pin seats 19 support the rotation of the support rod 18, allowing for angle adjustment of the scraper 14. A tension spring 20 is located above the pin seats 19 and connected to the support rod 18 at the front end of the three-roll mill 1. This spring provides elastic upward pull on the support rod 18, ensuring elastic contact between the scraper 14 and the third roller 13, thus ensuring the cleaning of the sheet material on the third roller 13.

[0026] The pressing block 15 is vertically and flexibly positioned in the feed port 16. In this embodiment, the length of the pressing block 15 along the axial direction of the first roller 11 is less than the length of the feed port 16 along the axial direction of the first roller 11. The pressing block 15 is smaller than the feed port 16. During the lifting and lowering process of the pressing block 15, it does not obstruct the descent of the colored pencil refill material in the feed port 16. Moreover, the lifting and lowering of the pressing block 15 in the feed port 16 also prevents the colored pencil refill material from clogging the feed port 16. Figure 2 As shown, ensure smooth material feeding for extrusion and dispersion.

[0027] like Figure 4 As shown, the pressing block driving mechanism includes a top rod 4, a motor 9, a turntable 5, and a drive rod 6. The top rod 4 is located on top of the pressing block 15 and extends upward to above the hopper 2. In this embodiment, the hopper 2 is provided with a guide sleeve 10 corresponding to the top rod 4 for guiding the lifting and lowering of the top rod 4. The top rod 4 is connected to the top of the pressing block 15 by a threaded connection for synchronous lifting and lowering.

[0028] A floating seat 7 is provided at the top of the top rod 4. The motor 9 is horizontally provided at the top of the hopper 2. The turntable 5 is vertically provided on the rotating shaft of the motor 9 and located on one side of the floating seat 7. A guide groove 8 is provided horizontally in the floating seat 7. The drive rod 6 is eccentrically provided on the turntable 5 and extends into the guide groove 8. A bearing located in the guide groove 8 is provided on the drive rod 6 to reduce friction.

[0029] The rotation of the turntable 5 driven by motor 9 causes the eccentric rotation of the drive rod 6, changing its position and height during rotation. The height of the floating seat 7 is changed by the cooperation of the drive rod 6 and the guide groove 8. The floating seat 7 is connected to the top of the push rod 4 by a thread, thus achieving synchronous lifting and lowering of the push rod 4 and the floating seat 7, determining the reciprocating lifting and lowering of the pressure block 15. Furthermore, the descent of the pressure block 15 presses down the raw material located above the gap between the first roller 11 and the second roller 12, preventing the raw material from floating above and failing to enter the gap, ensuring the efficiency of extrusion production and reducing energy consumption.

[0030] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
