Description

Technical Field

[0001] This utility model relates to a melting device, specifically a high-temperature melting device for producing molding strips, belonging to the field of molding strip production technology. Background Technology

[0002] Mold release strips are a type of mold lubricant used to protect and lubricate the surface of molds after cleaning. They offer advantages such as saving cleaning time, increasing production capacity, not solidifying at room temperature, good moldability, ease of operation, and no damage to the mold. The production of mold release strips requires a high-temperature melting device to melt the plastic material, facilitating subsequent processing and reshaping into the strip shape.

[0003] According to patent CN217802663U, a high-temperature melting device for plastic masterbatch is disclosed, which includes a melting tank and a heating component. The melting tank is provided with a feed inlet on top, and a protective component is provided at the intersection of the melting tank and the feed inlet. The protective component includes a protective cover connected to the melting tank, and a cover plate is provided inside the protective cover.

[0004] The above solution can prevent the flue gas inside the melting tank from overflowing from the feed port during implementation. However, the above solution is difficult to make the material heat evenly during implementation. When the crushed plastic material enters the melting tank, it is easy to squeeze each other, resulting in the intermediate material being heated less and reducing the melting speed of the material. To this end, we provide a high-temperature melting device for producing mold lubricating strips to solve the above problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] The purpose of this invention is to provide a high-temperature melting device for producing molding compound strips in order to solve the above-mentioned problems, thereby addressing the issue in the prior art where uneven heating of plastic raw materials after entering the melting kettle leads to a slower melting rate in the middle of the material.

[0007] (II) Technical Solution

[0008] This utility model is achieved through the following technical solution: a high-temperature melting device for producing molding compound strips, comprising a melting tank, a high-temperature melting vessel fixedly connected inside the melting tank, an electric heating coil sleeved on the outside of the high-temperature melting vessel, a stirring mechanism inside the high-temperature melting vessel, the stirring mechanism comprising a support mounting frame, a fixed sleeve fixedly connected to the bottom surface of the support mounting frame, a transmission adjusting column slidably connected inside the fixed sleeve, a stirring rod fixedly connected to the bottom end of the transmission adjusting column, and a set of stirring blades fixedly connected to the outer surface of the stirring rod.

[0009] Preferably, both ends of the electric heating coil are fixedly connected to the melting tank, and the support mounting bracket is fixed to the top surface of the melting tank. The electric heating coil can perform high-temperature heating operations on the high-temperature melting vessel.

[0010] Preferably, a transmission telescopic rod is fixedly connected to the bottom surface of the support mounting frame, and the telescopic end of the transmission telescopic rod is fixedly connected to the transmission adjusting column, providing space for the raising and lowering of the transmission adjusting column.

[0011] Preferably, the inner wall of the fixed sleeve is provided with a limiting groove, which surrounds the inner wall of the fixed sleeve. The limiting groove can limit the sliding of the limiting slider, so that the limiting slider drives the transmission adjustment column to reciprocate up and down during rotation.

[0012] Preferably, a limiting slider is fixedly connected to the outer surface of the transmission adjusting column. The limiting slider slides inside the limiting groove, and the end of the limiting slider is spherically designed to increase the stability of sliding in the limiting groove.

[0013] Preferably, a barrier filter is fixedly connected inside the high-temperature melting vessel, and the stirring rod is slidably connected to the barrier filter, which can block the plastic material inside the high-temperature melting vessel.

[0014] Preferably, the bottom end of the high-temperature melting vessel is fixedly connected to a discharge pipe, and a control valve is fixedly installed inside the discharge pipe. The control valve facilitates the adjustment of the flow rate of the solution inside the discharge pipe.

[0015] Preferably, a support tripod is fixedly connected to the bottom surface of the melting tank, and a PLC control box is fixedly installed on the outer surface of the melting tank. The support tripod serves to support the operation of the device.

[0016] This utility model provides a high-temperature melting device for producing mold lubricating strips, which has the following beneficial effects:

[0017] 1. This utility model, by setting up components such as a fixed sleeve, transmission adjustment column, stirring rod, and stirring blade, and through the cooperation between the limiting slide groove and the limiting slider, allows the transmission adjustment column to reciprocate up and down inside the fixed sleeve during rotation. This enables the stirring rod and stirring blade to better and more thoroughly stir the plastic material inside the high-temperature melting kettle, ensuring that the material inside the high-temperature melting kettle is heated evenly. This prevents the material in the middle from heating slowly due to its greater distance from the inner wall of the high-temperature melting kettle, thus reducing the melting speed of the device and improving the production efficiency of the lubricating strip.

[0018] 2. This utility model, through the setting of the blocking filter screen, allows the molten plastic solution to flow through the filter holes to the bottom of the melting tank, while the unmelted plastic raw materials are blocked on the blocking filter screen, so that the raw materials are heated evenly by the stirring of the stirring blades, thereby improving the melting speed of the device; through the setting of the discharge pipe and control valve, it is convenient to discharge the molten plastic solution inside the high-temperature melting kettle into the mold for subsequent processing and shaping, and the flow rate of the solution can be controlled.

[0028] This utility model embodiment provides a high-temperature melting device for producing lubricating strips.

[0029] Please see Figure 1 The device includes a melting tank 1, with a supporting tripod 8 fixedly connected to the bottom of the melting tank 1. The supporting tripod 8 serves to fix and support the entire device for high-temperature melting operations. The production process of the molding strip includes several steps such as crushing, melting and remanufacturing. The production of the strip can reduce the accumulation of waste, reduce waste disposal costs, and provide a stable supply of recycled materials for the plastic products supply chain.

[0030] A PLC control box 9 is fixedly installed on the outer surface of the melting tank 1. The PLC control box 9 is existing technology and is electrically connected to the various electronic components inside the device via wires. The PLC control box 9 can set parameters for each electronic component of the device and control its operation and shutdown, which facilitates the automatic high-temperature melting of plastic materials and improves the automation level of the device. A hardened glass observation window is installed on the outside of the melting tank 1 to facilitate the observation of the inside of the melting tank 1 by the staff.

[0031] Please see Figure 1 , Figure 2 and Figure 3 The melting tank 1 is fixedly connected to a high-temperature melting vessel 2. An electric heating coil 3 is sleeved on the outside of the high-temperature melting vessel 2. Both ends of the electric heating coil 3 are fixedly connected to the melting tank 1. The high-temperature melting vessel 2 can hold the crushed plastic raw materials and heat the whole body of the high-temperature melting vessel 2 at high temperature through the electric heating coil 3, so that the material inside the high-temperature melting vessel 2 can be melted by heat, thereby facilitating the subsequent production of the molding strip. The electric heating coil 3 is prior art and will not be described in detail in this application.

[0032] A baffle screen 5 is fixedly connected inside the high-temperature melting vessel 2. The stirring rod 404 is slidably connected to the baffle screen 5. The baffle screen 5 has filter holes, which allow the molten plastic solution to flow through the filter holes to the bottom of the melting tank 1. The unmelted plastic raw materials are blocked on the baffle screen 5 so that the raw materials are heated evenly by the stirring of the stirring blade 405, thereby improving the melting speed of the device. The baffle screen 5 can provide a certain support for the lifting and rotation of the stirring rod 404, so that the stirring rod 404 can remain stable during the rotation and lifting process.

[0033] The bottom end of the high-temperature melting kettle 2 is fixedly connected to a discharge pipe 6. A control valve 7 is fixedly installed inside the discharge pipe 6. The discharge pipe 6 facilitates the discharge of the molten plastic solution inside the high-temperature melting kettle 2 into the mold for subsequent processing and shaping. The control valve 7 can restrict the flow space inside the discharge pipe 6, thereby controlling the flow rate of the solution inside the discharge pipe 6. The control valve 7 is a common existing technology, and will not be described in detail in this application.

[0034] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5The high-temperature melting vessel 2 is equipped with a stirring mechanism 4. The stirring mechanism 4 includes a support mounting frame 401, which is fixed to the top surface of the melting tank 1. The support mounting frame 401 can provide support for the operation of each component in the stirring mechanism 4. If it is desired to absorb the waste gas generated during the melting process, a gas purification device can be installed on the support mounting frame 401 during production. The gas purification device is not within the scope of this application, so it will not be described in detail.

[0035] A fixed sleeve 402 is fixedly connected to the bottom surface of the support mounting bracket 401. A transmission adjusting column 403 is slidably connected inside the fixed sleeve 402. A limiting groove 407 is opened on the inner wall of the fixed sleeve 402, and the limiting groove 407 surrounds the inner wall of the fixed sleeve 402. A limiting slider 408 is fixedly connected to the outer surface of the transmission adjusting column 403. The limiting slider 408 slides inside the limiting groove 407. When the transmission adjusting column 403 rotates inside the fixed sleeve 402, the limiting slider 408 on its surface will also rotate. Under the limiting action of the limiting groove 407, the rotation of the limiting slider 408 will drive the transmission adjusting column 403 to slide and rise and fall inside the fixed sleeve 402. The transmission adjusting column 403 can slide and rise and fall while rotating, thereby driving the stirring rod 404 to rotate and reciprocate to a certain height inside the high-temperature melting kettle 2.

[0036] A stirring rod 404 is fixedly connected to the bottom end of the transmission adjusting column 403. A set of stirring blades 405 are fixedly connected to the outer surface of the stirring rod 404. When the stirring rod 404 moves up and down and rotates with the transmission adjusting column 403 inside the high-temperature melting kettle 2, the stirring blades 405 can fully stir the raw materials inside the high-temperature melting kettle 2 and re-drive the material accumulated on the top surface of the barrier filter screen 5. This improves the melting speed of the internal plastic material and prevents the material from accumulating on the top surface of the barrier filter screen 5 and clogging the filter holes on the barrier filter screen 5, ensuring that the melting operation inside the device can be carried out efficiently.

[0037] Please see Figure 5 A transmission telescopic rod 406 is fixedly connected to the bottom surface of the support mounting frame 401. The telescopic end of the transmission telescopic rod 406 is fixedly connected to the transmission adjusting column 403. The transmission telescopic rod 406 provides space for the lifting and lowering of the transmission adjusting column 403. A stirring motor is fixedly installed on the top surface of the support mounting frame 401. The transmission telescopic rod 406 passes through the support mounting frame 401 and is fixedly connected to the output shaft of the stirring motor. When the stirring motor starts, it can drive the transmission telescopic rod 406 to rotate. The rotation of the transmission telescopic rod 406 can drive the transmission adjusting column 403 to rotate inside the fixed sleeve 402, thereby providing power for the subsequent stirring of the stirring rod 404 and stirring blade 405.

[0038] Working principle: When the operator wants to perform high-temperature melting of crushed plastic materials, the crushed materials are first added to the high-temperature melting kettle 2. Then, the electric heating coil 3 is started by controlling the PLC control box 9. The electric heating coil 3 can heat and melt the raw materials inside the high-temperature melting kettle 2. Then, the stirring motor installed on the support mounting frame 401 is started. The stirring motor can drive the transmission telescopic rod 406 to rotate. The rotation of the transmission telescopic rod 406 can drive the transmission adjusting column 403 to rotate inside the fixed sleeve 402. Under the action of the limiting slide groove 407 and the limiting slider 408, the transmission adjusting column 403 will slide up and down inside the fixed sleeve 402 while rotating, thereby driving the stirring rod 404 to rotate inside the high-temperature melting kettle 2 and reciprocate up and down. During the movement of the stirring rod 404, the stirring blade 405 can stir the plastic raw materials inside the high-temperature melting kettle 2, so that they are heated evenly. After melting is completed, the operator can discharge the plastic solution through the discharge pipe 6.
