Description

Technical Field

[0001] This utility model relates to the technical field of crayon production, and in particular to a cooling mechanism for crayon production. Background Technology

[0002] Crayons or oil pastels are pencils made by mixing pigments with wax. They come in dozens of colors and are used for drawing. The manufacturing process typically involves heating the raw material to a suitable temperature to form a liquid, then placing it in a mold to cool and solidify. Finally, the liquid is pressed out of the mold to become the finished crayon. The molded crayons generally need to be cooled to room temperature. Currently, the crayon mold is usually placed near a fan for cooling. This cooling method is inefficient, especially when the outside air temperature is high, requiring a long waiting time and reducing the efficiency of crayon production. Utility Model Content

[0003] The present invention aims to overcome the shortcomings of low cooling efficiency in the prior art by providing a cooling mechanism for crayon production that rapidly cools down the crayon through contact with a low-temperature object.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A cooling mechanism for crayon production includes a cooling pipe and a rotating shaft. The cooling pipe has a cooling cavity, and the rotating shaft is placed inside the cooling cavity and rotatably connected to the cooling pipe. The rotating shaft has several circumferentially distributed placement slots, and a heat dissipation cavity is mounted on the rotating shaft. A cooling fan is installed inside the heat dissipation cavity.

[0006] The cooling pipe is equipped with a cooling chamber. The rotating shaft is placed inside the cooling chamber and rotates. The rotation of the rotating shaft pushes the crayon to move within the cooling chamber. The rotating shaft has several placement slots to hold the crayon. The crayon is placed in the placement slot and contacts the rotating shaft. During the rotation of the rotating shaft, the cooling fan installed in the cooling chamber cools the rotating shaft. Then, the rotating shaft absorbs the heat from the crayon for cooling, thus achieving the purpose of rapid cooling through contact with a low-temperature object.

[0007] Preferably, the cooling pipe has an arc-shaped cross-section, the cooling chamber is open at the top, a feed plate is installed at one end of the cooling pipe, and a discharge plate is installed at the other end. Baffles are installed on both sides of the feed plate and the discharge plate. The arc-shaped cross-section of the cooling pipe facilitates the rotation of the rotating shaft and ensures that the upper end of the cooling chamber is open for easy feeding and discharging. The feed plate and discharge plate are installed at both ends of the cooling pipe, and baffles are installed on both sides of the feed plate and the discharge plate to limit the movement of the crayons, ensuring that the crayons can enter the placement groove of the rotating shaft. This design facilitates feeding and discharging.

[0008] Preferably, the rotating shaft is matched with the cooling chamber. One end of the rotating shaft is provided with a rotating rod, one end of which is connected to the rotating shaft. The other end of the rotating shaft passes through a cooling pipe and is positioned at the other end of the cooling pipe. A gear is installed at the end of the rotating rod that passes through the cooling pipe. A motor is installed on the cooling pipe, and a gear is installed on the motor shaft of the motor. Gears 1 and 2 mesh. The rotating rod on the rotating shaft, with gear 1 installed at the end that passes through the cooling pipe, drives the rotating shaft to rotate within the cooling chamber through the rotation of the motor and the meshing of gears 1 and 2. This rotates the slot containing the crayons to the bottom of the cooling chamber. The rotation within the cooling chamber increases the contact time with the rotating shaft, resulting in better cooling. This design allows the rotating shaft to rotate within the cooling chamber.

[0009] Preferably, the heat dissipation cavity is open at one end of the rotating shaft, and the cooling fan is installed inside and matched with the heat dissipation cavity. The placement slot has several evenly distributed air outlets, which communicate with the cooling fan. The heat dissipation cavity is located inside the rotating shaft and is open at one end. By installing the cooling fan at the open end of the heat dissipation cavity, the fan blows air into the cavity, which is then released through the air outlets on the bottom surface of the placement slot. A mounting hole for the cooling fan is provided on one side of the cooling cavity. The evenly distributed air outlets allow for comprehensive heat dissipation of the crayons in the placement slot, while the cooling fan simultaneously cools the rotating shaft. This design provides comprehensive heat dissipation.

[0010] Preferably, ejector bars are installed on both sides of the cooling chamber. The ejector bars have an arc-shaped cross-section. Ejector grooves are provided at both ends of the rotating shaft, and these grooves match the ejector bars. One end of each ejector bar corresponds to the discharge plate, and the other end corresponds to the placement groove. When the crayon rotates to the discharge plate, it needs to be pushed onto the discharge plate for dispensing. Therefore, ejector grooves are installed at both ends of the rotating shaft, and the two ends of the crayon are placed within these grooves. Ejector bars are installed at both ends of the cooling chamber, and these grooves are placed within the ejector grooves. One end of each ejector bar corresponds to the bottom of the placement groove, and the other end corresponds to the discharge plate. When the crayon rotates to the discharge plate, the two ends of the crayon contact the arc-shaped ejector bars, which push the crayon out of the placement groove and onto the discharge plate. This design facilitates rapid dispensing.

[0011] Preferably, the bottom surface of the cooling chamber is provided with heat exchange holes, and a heat exchange plate is installed inside the heat exchange holes. The heat exchange plate matches the heat exchange holes and is connected to the cooling pipes. In order to prevent heat from accumulating in the cooling chamber and hindering heat dissipation, heat exchange holes are opened on the bottom surface of the cooling chamber, and matching heat exchange plates are installed inside the heat exchange holes. The heat exchange plates are made of thin plates with good thermal conductivity. This design can reduce the temperature of the cooling chamber.

[0012] The beneficial effects of this utility model are: rapid cooling through contact with low-temperature objects, easy feeding and discharging, the ability to drive the rotating shaft to rotate in the cooling chamber, comprehensive heat dissipation, easy rapid material discharge, and reduction of the temperature of the cooling chamber.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0019] like Figure 1 , Figure 2 In the embodiment shown, a cooling mechanism for crayon production includes a cooling pipe 1 and a rotating shaft 2. The cooling pipe 1 is provided with a cooling cavity 3. The rotating shaft 2 is placed in the cooling cavity 3 and rotatably connected to the cooling pipe 1. The rotating shaft 2 is provided with a plurality of circumferentially distributed placement slots 4. The rotating shaft 2 has a heat dissipation cavity 5, and a heat dissipation fan 6 is installed in the heat dissipation cavity 5.

[0020] like Figure 3 As shown, the cross-sectional shape of the cooling pipe 1 is arc-shaped, the upper end of the cooling chamber 3 is open, one end of the cooling pipe 1 is equipped with a feed plate 7, the other end of the cooling pipe 1 is equipped with a discharge plate 8, and baffles 9 are installed on both sides of the feed plate 7 and the discharge plate 8.

[0021] like Figure 4As shown, the rotating shaft 2 is matched with the cooling chamber 3. One end of the rotating shaft 2 is provided with a rotating rod 10. One end of the rotating rod 10 is connected to the rotating shaft 2. The other end of the rotating shaft 2 passes through the cooling pipe 1 and is placed at the other end of the cooling pipe 1. A gear 11 is installed at the end of the rotating rod 10 that passes through the cooling pipe 1. A motor 12 is installed on the cooling pipe 1. A gear 2 13 is installed on the motor shaft of the motor 12. Gear 11 and gear 2 13 mesh.

[0022] The heat dissipation cavity 5 is open at one end of the rotating shaft 2. The cooling fan 6 is installed in the heat dissipation cavity 5 and matches the heat dissipation cavity 5. The placement slot 4 is provided with several evenly distributed air outlet holes 14, which are connected to the cooling fan 6.

[0023] Both sides of the cooling chamber 3 are equipped with ejector bars 15. The cross-sectional shape of the ejector bars 15 is arc-shaped. Both ends of the rotating shaft 2 are provided with ejector grooves 16. The ejector grooves 16 match the ejector bars 15. One end of the ejector bars 15 corresponds to the discharge plate 8, and the other end of the ejector bars 15 corresponds to the placement groove 4.

[0024] The bottom surface of the cooling chamber 3 is provided with heat exchange holes 17, and a heat exchange plate 18 is provided inside the heat exchange holes 17. The heat exchange plate 18 matches the heat exchange holes 17 and is connected to the cooling pipe 1.

[0025] When the finished crayons need to be cooled, the crayons are placed on the feed plate 7 and the baffle 9 restricts the crayons on the feed plate 7. The crayons at the bottom fall into the placement groove 4 of the rotating shaft 2. Then the motor 12 is activated, and the rotating shaft 2 is driven to rotate in the cooling chamber 3 through the meshing of gear 11 and gear 2 13, so that the crayons enter the placement groove 4 in sequence.

[0026] Then the cooling fan 6 is activated, blowing air into the cooling cavity 5, and then the air is discharged through the air outlet 14 on the bottom of the placement slot 4. The air outlet 14 dissipates heat from the crayon. The air blown by the cooling fan 5 absorbs the heat from the crayon through the rotating shaft 2, thereby quickly cooling the crayon.

[0027] After cooling, the crayon rotates to the other end and is received by the discharge plate 8. When the crayon rotates to the position corresponding to the discharge plate 8, both ends of the crayon come into contact with the ejector bar 15 in the ejector groove 16. Guided by the ejector bar 15, the crayon is pushed out of the placement groove 4 and onto the discharge plate 8.
