Description

Technical Field

[0001] This utility model relates to a rosin refining and melting device, belonging to the field of rosin processing technology. Background Technology

[0002] Rosin is a mixture secreted by pine trees, mainly composed of turpentine and resin acids. In the refining process of rosin, the rosin refining melting device is a special equipment used for melting and processing rosin resin. This device usually has heating and melting functions, which can efficiently convert solid rosin resin into liquid for subsequent processing or application.

[0003] In existing rosin refining and melting equipment, the crushed rosin raw material is usually poured into a heating tank and melted while being stirred. However, considering that rosin itself has high viscosity and surface tension, a large number of bubbles are easily generated during stirring. If these bubbles are not removed in time, their presence will damage the uniformity of the product, reduce the quality of the refined rosin product, and not only hinder the stable production of the equipment, but also affect the production efficiency of the equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rosin refining and melting device to solve the problem that existing rosin refining and melting devices are prone to retaining air bubbles during use, which affects the quality of the refined rosin product.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rosin refining and melting device includes an insulated outer tank, a limiting support fixedly connected to the inner side of the insulated outer tank, a melting inner tank fixedly installed at the middle position of the inner side of the limiting support, a top cover fixedly installed on the top of the insulated outer tank, a limiting disc extending into the interior of the melting inner tank fixedly connected to the middle position of the bottom of the top cover, electric push rods fixedly installed on both sides of the bottom of the limiting disc, a limiting block fixedly connected to the movable end of the electric push rod, a limiting track slidably connected to the outside of the limiting block, a ring plate fixedly connected to the bottom end of the limiting track, a rotating rod with a pointed needle fixedly connected to the bottom left, right, front and back positions of the ring plate, a telescopic rod fixedly connected to the top surface of the ring plate near the middle hole, a sleeve slidably connected to the upper part of the telescopic rod, and a toothed ring fixedly connected to the outside of the sleeve.

[0007] Preferably, a heating ring tube is fixedly installed inside a limiting support frame and sleeved on the outer side of the inner melting tank. A conical discharge end at the bottom of the inner melting tank extends outwards through the bottom of the outer insulated tank. A bracket is fixedly connected to the lower outer side of the outer insulated tank. When the heating ring tube is energized and heats the rosin raw material inside the inner melting tank, the limiting support frame serves to separately limit and support the inner melting tank and the heating ring tube.

[0008] Preferably, a drive motor is fixedly installed at the center of the top surface of the top cover, and a feed inlet is connected to the left side of the top surface of the top cover, with the outlet of the feed inlet extending into the interior of the molten inner tank. The feed inlet assists workers in quickly adding rosin raw materials into the molten inner tank.

[0009] Preferably, the output end of the drive motor is fixedly connected to a drive spindle extending into the inner molten tank. A gear is fixedly connected to the drive spindle at a position slightly above the gear ring. The gear and the gear ring are meshed together. A stirring rod is fixedly installed on the outer side of the drive spindle, and multiple sets of the stirring rods are arranged inside the inner molten tank.

[0010] Preferably, the drive spindle passes through the interior of the limiting disc, the ring plate, and the limiting track. The bottom end of the limiting disc has an annular groove structure that is slidably connected to the sleeve. The tip of the rotating rod with the pointed needle faces downward. The lower part of the limiting block has a spherical structure. The two telescopic rods on the left and right are located inside the limiting track. The electric push rod and the telescopic rod are arranged on the same horizontal line.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the gears, toothed rings, sleeves, telescopic rods, ring plates, and rotating rods with pointed needles facilitate the refining and melting of rosin raw materials inside the inner melting tank via the heated ring tube. Under the transmission of the drive shaft and gears, the bubble removal structure, composed of gears, toothed rings, sleeves, telescopic rods, ring plates, and rotating rods with pointed needles, quickly removes bubbles generated inside the device. This prevents the persistent presence of bubbles from disrupting the uniformity of the product and reducing the quality after refining, thus promoting stable production and improving the device's efficiency. Furthermore, the bubble removal structure works in conjunction with a lifting structure composed of electric push rods, limiting blocks, and limiting tracks, allowing the device to adjust the operating height of the bubble removal structure to improve its efficiency in removing bubbles.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, but the present invention is not limited to the embodiments. Specific experimental conditions and methods not specified in the following embodiments are generally conventional methods well known to those skilled in the art.

[0018] Example 1: A rosin refining and melting device includes an insulated outer tank 1, a limiting support 20 fixedly connected to the inner side of the insulated outer tank 1, a melting inner tank 2 fixedly installed at the middle position of the inner side of the limiting support 20, a top cover 3 fixedly installed on the top of the insulated outer tank 1, a limiting disc 4 extending into the interior of the melting inner tank 2 fixedly connected to the middle position of the bottom of the top cover 3, electric push rods 12 fixedly installed on both sides of the bottom of the limiting disc 4, a limiting block 13 fixedly connected to the movable end of the electric push rod 12, a limiting track 14 slidably connected to the outside of the limiting block 13, a ring plate 10 fixedly connected to the bottom end of the limiting track 14, a rotating rod 11 with a pointed needle fixedly connected to the bottom left, right, front and back positions of the ring plate 10, a telescopic rod 9 fixedly connected to the top surface of the ring plate 10 near the middle hole, a sleeve 8 slidably connected to the upper part of the telescopic rod 9, and a toothed ring 7 fixedly connected to the outside of the sleeve 8.

[0019] Example 2: As Figures 1-3 As shown, the difference between the rosin refining and melting device described in this embodiment and that described in Embodiment 1 is only that the outer side of the inner melting tank 2 is fitted with a heating ring pipe 16 fixedly installed inside the limiting support 20, and the conical discharge end provided at the lower part of the inner melting tank 2 extends outward through the bottom of the outer heat-insulating tank 1. The lower part of the outer side of the outer heat-insulating tank 1 is fixedly connected with a bracket 17. When the heating ring pipe 16 is energized and heated to heat the rosin raw material inside the inner melting tank 2, the limiting support 20 serves to limit and support the inner melting tank 2 and the heating ring pipe 16 respectively.

[0020] A drive motor 19 is fixedly installed at the middle of the top surface of the top cover 3. A feed inlet 18 is connected to the left side of the top surface of the top cover 3. The discharge end of the feed inlet 18 extends into the interior of the molten inner tank 2. The feed inlet 18 is designed to assist workers in quickly adding rosin raw materials into the molten inner tank 2.

[0021] The output end of the drive motor 19 is fixedly connected to a drive spindle 5 extending into the inner melting tank 2. A gear 6 is fixedly connected to the drive spindle 5 at a slightly above position opposite the gear ring 7. The gear 6 and the gear ring 7 are meshed together. A stirring rod 15 is fixedly installed on the outside of the drive spindle 5. Multiple stirring rods 15 are arranged inside the inner melting tank 2. The gear 6 and the gear ring 7 are connected by a sleeve and meshing arrangement, which facilitates the synchronous rotation of the drive spindle 5 through the gear 6 and the gear ring 7. The drive spindle 5 passes through the limiting disc 4, the ring plate 10, and the limiting rail. Inside track 14, the bottom end of the limiting disc 4 is provided with an annular groove structure that slides together with the sleeve 8. The tip of the needle-shaped rotating rod 11 is set downwards. The lower part of the limiting block 13 is set with a spherical structure. The left and right telescopic rods 9 are set inside the limiting track 14. The electric push rod 12 and the telescopic rods 9 are arranged on the same horizontal line. The spherical structure of the lower part of the limiting block 13 not only does not affect the normal synchronous rotation operation of the limiting track 14, but also serves to ensure that the moving end of the electric push rod 12 and the limiting track 14 are always connected together.

[0022] The workflow described in this embodiment is as follows:

[0023] The electrical energy required for the start-up and operation of this device comes from an external power source. Before using the device, the top cover 3 must be securely installed on the top of the insulated outer tank 1, ensuring that the stirring structure and bubble removal structure inside the top cover 3 extend into the interior of the melting inner tank 2. When using this device during the refining and processing of rosin, first close the control valve at the discharge end of the melting inner tank 2, and add an appropriate amount of crushed rosin raw material into the interior of the melting inner tank 2 through the feed port 18. After the material is discharged, under the connection constraint of the limiting support 20, the heating ring pipe 16, continuously powered by the external power source, is energized and started to heat and melt the rosin raw material inside the melting inner tank 2. At the same time, after heating for a period of time, under the connection constraint of the top cover 3 and the limiting disc 4, the drive motor 19 is started, driving the gear 6 and multiple sets of stirring rods 15 to rotate, to assist in stirring the rosin raw material inside the melting inner tank 2, promoting uniform heating of the rosin raw material, and heating the rosin raw material into a liquid state. Considering that liquid rosin raw material is prone to generating bubbles during melting and refining, in order to address this problem, the following measures are taken: Before the liquid rosin raw material is stirred, under the connection constraint of the limiting disc 4 and the sleeve 8, the two electric push rods 12 are activated to extend and retract downwards. The limiting block 13 pushes down the limiting track 14, causing the limiting track 14 and the ring plate 10 to move downwards along with the telescopic rod 9 and the needle-equipped rotating rod 11. This allows the multiple needles at the lower part of the needle-equipped rotating rod 11 to descend to the surface of the liquid rosin raw material. Once the lifting and lowering is in place, the operation of the electric push rods 12 is stopped. Then, the main shaft 5 drives the gear 6 and the stirring structure to mix and stir the liquid rosin raw material, and the liquid surface... When a large number of bubbles are generated, the toothed ring 7 will rotate through the sleeve 8, telescopic rod 9, ring plate 10, limiting track 14 and multiple needle-equipped rotating rods 11 under the driving action of meshing transmission. This allows the device to puncture and remove the large number of bubbles generated on the surface of the liquid rosin raw material through multiple rows of needles, preventing the bubbles from remaining and affecting the production quality of subsequent products. Finally, after the melting process is completed, the control valve at the discharge end of the melting inner tank 2 is opened, and the liquid rosin raw material will be discharged outwards, completing the entire refining and melting operation with the device.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
