Description

Technical Field

[0001] This utility model relates to the field of organosilicon technology, and in particular to production equipment for organosilicon plastic additives. Background Technology

[0002] Organosilicon plastic additives, also known as granular organosilicon plastic additives, are composites of high-content ultra-high molecular weight organosilicon polymers supported on extremely fine powder carriers. They are compatible with almost all types of thermoplastic plastics and are widely applicable to various thermoplastic plastic processing technologies, reducing processing energy consumption and improving the quality of plastic products.

[0003] In the prior art, such as Chinese Patent No. CN211763370U, a production equipment for organosilane additives is disclosed. This equipment solves the problems of low mixing efficiency in single-shaft driven extruders used for organosilane additive preparation, and the easy impact of air bubbles in the raw materials on product quality. The equipment includes a base, with an extrusion cylinder connected to the upper end of the base via a bracket. In this invention, a motor drives a first connecting shaft to rotate, and under the transmission of a first herringbone gear and a second herringbone gear, a second connecting shaft rotates synchronously. This causes the first and second spiral shafts to rotate in opposite directions to mix the raw materials. Compared to the existing single-shaft mixing method, this dual-shaft mixing and transmission method results in higher mixing efficiency and smoother transmission. When the raw materials are spirally extruded and mixed in the extrusion cylinder, the gas contained within can flow with the raw materials and be discharged outwards through the air holes on the end cap via the air outlet pipe, avoiding the formation of air bubbles and effectively reducing the impact of gas on the product.

[0004] While the above-mentioned solution has the advantages mentioned above, it also has the following disadvantages: Although it can drive the first connecting shaft to rotate via a motor, causing the first herringbone gear to mesh with the second herringbone gear, and then the second connecting shaft to rotate synchronously, thus making the first and second spiral shafts rotate in opposite directions to mix the raw materials, resulting in higher mixing efficiency and smoother transmission compared to the existing single-shaft mixing method, when the molten plastic is extruded into plastic filaments through the die, at the beginning of the equipment operation, if the heating temperature has not reached the temperature required for the raw materials to fully melt or the temperature distribution is uneven, the initially extruded plastic filaments may stick to the outside of the die extrusion nozzle and cool into clumps, which can easily scratch the plastic filaments extruded later. Workers need to use tools to remove them, and workers may suffer burns due to improper operation, posing a certain danger. In addition, when the gas inside the extrusion cylinder is discharged through the gas outlet pipe and vent, it can easily carry away heat, resulting in heat waste. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art. Although the first connecting shaft can be driven by a motor to rotate, so that the first herringbone gear and the second herringbone gear mesh, and the second connecting shaft rotates synchronously, so that the first and second spiral shafts rotate in opposite directions to mix the raw materials, which is more efficient and has a smoother transmission than the existing single-shaft mixing method, when the molten plastic is extruded into plastic filaments through the die, at the beginning of the equipment operation, the heating temperature may not reach the temperature required for the raw materials to be fully melted or the temperature distribution may be uneven. The initially extruded plastic filaments may stick to the outside of the die extrusion port and cool into clumps, which may scratch the plastic filaments extruded later. Workers need to use tools to remove them. Workers may be burned due to improper operation, which poses a certain danger. In addition, when the gas inside the extrusion cylinder is discharged through the gas outlet pipe and gas hole, it is easy to carry away heat, resulting in heat waste.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: Organosilicon plastic additive production equipment, comprising: a machine body, and further comprising:

[0007] Two auger screws are symmetrically rotatably connected to opposite sides of the inner wall of the machine body. One end of each auger screw is fixedly connected to a gear, and the teeth of the two gears mesh. A mounting plate is fixedly connected to one side of the machine body, and a motor is fixedly connected to the top of the mounting plate. The output end of the motor is fixedly connected to one end of one of the auger screws. An extrusion hole is provided on the other side of the machine body. Two U-shaped plates are symmetrically slidably connected to the outer surface of the machine body. A receiving frame is fixedly connected to opposite sides of the two U-shaped plates near the bottom. A lead screw is rotatably connected to opposite sides of the inner wall of one of the U-shaped plates. An L-shaped block is slidably connected inside the U-shaped plate, and one of the L-shaped blocks is threadedly connected to the lead screw. A scraper is fixedly connected to opposite sides of the two L-shaped blocks. A second motor is fixedly connected to the top of one of the U-shaped plates, and the output end of the second motor is fixedly connected to one end of the lead screw.

[0008] Preferably, a guide rod is fixedly connected to the opposite side of the inner wall of another U-shaped plate, and another L-shaped block is slidably connected to the guide rod, the width of the L-shaped block being equal to the width of the inner wall of the U-shaped plate.

[0009] Preferably, two positioning holes are symmetrically opened on the top of the body, a positioning rod is slidably connected to the top of the U-shaped plate, one end of the positioning rod is slidably connected to the inside of the positioning hole, and a spring is provided on the outer surface of the positioning rod, and the spring is fixedly connected to the positioning rod and the U-shaped plate respectively.

[0010] Preferably, a feeding hopper is fixedly connected to the top of the machine body away from the extrusion hole, and two feeding pipes are symmetrically fixedly connected to the top of the feeding hopper, and the two feeding pipes, the feeding hopper and the machine body are connected in communication.

[0011] Preferably, the top of the machine body is fixedly connected to two air outlet pipes, one end of the two air outlet pipes is fixedly connected to a conveying pipe, one end of the conveying pipe is fixedly connected to an annular pipe, and the machine body, the two air outlet pipes, the two connecting pipes, the conveying pipe and the annular pipe are interconnected.

[0012] Preferably, the outer surface of the feed hopper near the top is fixedly connected with multiple diversion pipes in a circumferential array, and each of the multiple diversion pipes is fixedly connected to the annular pipe. The feed hopper is provided with a heating groove, and the annular pipe, the multiple diversion pipes and the heating groove are connected to each other.

[0013] Preferably, the bottom of the inner wall of the heating tank is provided with a plurality of exhaust holes in a circumferential array, the exhaust holes are set in an inclined shape, and the heating tank, the plurality of exhaust holes and the feed hopper are connected.

[0014] Preferably, the inner wall of the machine body is provided with a heating device.

[0015] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0016] 1. This utility model controls the start of motor two via a controller, causing its output shaft to drive the lead screw to rotate. Then, with one of the L-shaped blocks threadedly connected to the lead screw and with the inner wall of the U-shaped plate providing limiting and guiding for the L-shaped block, one of the L-shaped blocks can move downward along the outer surface of the lead screw, simultaneously driving the scraper downward. This causes the other L-shaped block to slide downward along the outer surface of the guide rod, allowing the scraper to remove the clumps of plastic adhering to the extrusion hole and causing the clumps of plastic to fall into the receiving frame. This eliminates the need for workers to use tools to remove the clumps, thus avoiding burns caused by improper operation and improving the safety of removing clumps of plastic.

The hot air flows from top to bottom, heating the feed hopper. The hot air then overflows from the exhaust port at the bottom and flows upward from the feed hopper, contacting the raw materials entering the feed hopper for preheating. This reduces the time and energy required for the heating device to heat the raw materials to a molten state, allowing for the reuse of heat and thus saving energy.

[0018] 3. In this utility model, by pulling the positioning rod upward by hand to disengage it from the inside of the positioning hole, the restriction on the U-shaped plate can be released, and the spring is stretched simultaneously. At this time, the U-shaped plate and receiving frame can be removed from the top of the machine body. Conversely, under the restoring force of the spring, the positioning rod can be inserted into the inside of the positioning hole to limit the U-shaped plate, thus completing the installation of the U-shaped plate and receiving frame. It is relatively simple and convenient, making it easy to install and disassemble the U-shaped plate and receiving frame. Attached Figure Description

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Examples, such as Figure 1-5 As shown, this utility model provides a production equipment for organosilicon plastic additives, including: a machine body 1, and two auger screws 101, symmetrically rotatably connected to opposite sides of the inner wall of the machine body 1. One end of each auger screw 101 is fixedly connected to a gear 102, the teeth of the two gears 102 meshing. A mounting plate 103 is fixedly connected to one side of the machine body 1, and a motor 104 is fixedly connected to the top of the mounting plate 103. The output end of the motor 104 is fixedly connected to one end of one of the auger screws 101. An extrusion hole 112 is provided on the other side of the machine body 1. Two U-shaped plates 2 are symmetrically slidably connected to the outer surface of the machine body 1. A receiving frame 201 is fixedly connected to the opposite side of the two U-shaped plates 2 near the bottom. A lead screw 202 is rotatably connected to the opposite side of the inner wall of one of the U-shaped plates 2. An L-shaped block 205 is slidably connected inside the U-shaped plate 2. One of the L-shaped blocks 205 is threadedly connected to the lead screw 202. A scraper 206 is fixedly connected to the opposite side of the two L-shaped blocks 205. A motor 203 is fixedly connected to the top of one of the U-shaped plates 2. The output end of the motor 203 is fixedly connected to one end of the lead screw 202.

[0029] Furthermore, such as Figure 1-5 As shown, a guide rod 204 is fixedly connected to the opposite side of the inner wall of another U-shaped plate 2, and another L-shaped block 205 is slidably connected to the guide rod 204. The width of the L-shaped block 205 is equal to the width of the inner wall of the U-shaped plate 2. With the above arrangement, the other L-shaped block 205 can slide up and down along the outer surface of the guide rod 204, which plays a certain supporting and guiding role for the scraper 206.

[0030] Furthermore, such as Figure 1-5 As shown, two positioning holes 113 are symmetrically opened on the top of the body 1. A positioning rod 207 is slidably connected to the top of the U-shaped plate 2. One end of the positioning rod 207 is slidably connected to the inside of the positioning hole 113. A spring 208 is provided on the outer surface of the positioning rod 207. The spring 208 is fixedly connected to the positioning rod 207 and the U-shaped plate 2 respectively. Under the reset force of the spring 208, the positioning rod 207 can be inserted into the inside of the positioning hole 113 to limit the U-shaped plate 2.

[0031] Furthermore, such as Figure 1-5As shown, a feed hopper 105 is fixedly connected to the top of the machine body 1 away from the extrusion hole 112. Two feed pipes 106 are symmetrically fixedly connected to the top of the feed hopper 105. The two feed pipes 106, the feed hopper 105 and the machine body 1 are connected. The raw materials for producing silicone plastic additives are added to the feed hopper 105 through the feed pipes 106 and enter the feed hopper 105.

[0032] Furthermore, such as Figure 1-5 As shown, two air outlet pipes 107 are fixedly connected to the top of the body 1. One end of the two air outlet pipes 107 is fixedly connected to a conveying pipe 109, and one end of the conveying pipe 109 is fixedly connected to an annular pipe 110. The body 1, the two air outlet pipes 107, the two connecting pipes 108, the conveying pipe 109 and the annular pipe 110 are connected. With the above arrangement, the hot air inside the body 1 can pass through the air outlet pipes 107, the connecting pipes 108 and the conveying pipe 109 in sequence and enter the annular pipe 110.

[0033] Furthermore, such as Figure 1-5 As shown, the outer surface of the feed hopper 105 near the top is fixedly connected with multiple diversion pipes 111 in a circumferential array. All the diversion pipes 111 are fixedly connected to the annular pipe 110. A heating tank 114 is opened inside the feed hopper 105. The annular pipe 110, the multiple diversion pipes 111 and the heating tank 114 are connected. With the above arrangement, hot air can enter the heating tank 114 through the annular pipe 110 and the diversion pipes 111 and flow downward.

[0034] Furthermore, such as Figure 1-5 As shown, the bottom of the inner wall of the heating tank 114 is provided with multiple vent holes 115 in a circumferential array. The vent holes 115 are set in an inclined shape. The heating tank 114, the multiple vent holes 115 and the feed hopper 105 are connected. By setting the vent holes 115 in an inclined shape, raw materials can be prevented from entering the vent holes 115. By blocking the vent holes 115, the hot air inside the heating tank 114 can be discharged into the feed hopper 105 through the vent holes 115.

[0035] Furthermore, such as Figure 1-5 As shown, a heating device is provided on the inner wall of the machine body 1, which facilitates the heating treatment of the raw materials inside the machine body 1.

[0036] Working principle: During use, the raw material for producing silicone plastic additives is added to the feed hopper 105 through the feed pipe 106 and enters the feed hopper 105. Then, the controller controls the motor 104 to start, causing its output shaft to drive one set of auger screws 101 and gears 102 to rotate. Then, under the meshing action of the two gears 102, the other set of auger screws 101 and gears 102 can rotate in opposite directions, mixing and conveying the raw material. The heating device heats the raw material to a molten state, and then it is extruded through the extrusion hole 112. The above is existing technology, so it will not be described in detail. When the extrusion hole 112 is sticky... When there is clumped plastic, the controller starts the motor 203, causing its output shaft to drive the lead screw 202 to rotate. Then, with one of the L-shaped blocks 205 threadedly connected to the lead screw 202 and with the inner wall of the U-shaped plate 2 providing limiting and guiding for the L-shaped block 205, one of the L-shaped blocks 205 can move downwards along the outer surface of the lead screw 202, simultaneously driving the scraper 206 downwards. This causes the other L-shaped block 205 to slide downwards along the outer surface of the guide rod 204, allowing the scraper 206 to scrape off the clumped plastic adhering to the extrusion hole 112 and cause the clumped plastic to fall into the receiving frame 201. This eliminates the need for manual operation. The tool removes the clumps of plastic, thus preventing burns to workers due to improper operation and improving safety during removal. By manually pulling the positioning rod 207 upwards, it disengages from the positioning hole 113, releasing the U-shaped plate 2 from its position. Simultaneously, the spring 208 is stretched, allowing the U-shaped plate 2 and receiving frame 201 to be removed from the top of the machine body 1. Conversely, the positioning rod 207 is inserted into the positioning hole 113 by the restoring force of the spring 208, limiting the U-shaped plate 2. This completes the installation of the U-shaped plate 2 and receiving frame 201, which is simple and convenient. The material frame 201 and other components are installed and disassembled. The hot air inside the machine body 1 enters the heating tank 114 through the air outlet pipe 107, connecting pipe 108, conveying pipe 109, annular pipe 110 and diversion pipe 111 in sequence. The hot air flows from top to bottom, heating the feed hopper 105. The hot air overflows from the exhaust hole 115 at the bottom and then flows upward from the feed hopper 105, so that the hot air comes into contact with the raw material entering the feed hopper 105 and preheats the raw material. This can appropriately reduce the time and energy consumption required for the heating device to heat the raw material to a molten state, and reuse the heat, thereby saving energy.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
