Description

Technical Field

[0001] This utility model relates to the field of material discharge control technology, and in particular to a polystyrene material discharge control device. Background Technology

[0002] Polystyrene is a polymer synthesized from styrene monomers through a free radical addition polymerization reaction. It is a colorless and transparent thermoplastic with a glass transition temperature above 100°C, making it frequently used to manufacture various disposable containers that need to withstand boiling water temperatures, as well as disposable foam lunch boxes. Polystyrene possesses excellent electrical insulation properties, making it a commonly used insulating material in the electronics and electrical appliance industries. It is hard and brittle, lacks ductility, has high surface hardness, and maintains good shape stability. Furthermore, it exhibits excellent processing properties, is easy to mold, and can be produced into various shapes and for different purposes through injection molding, extrusion, foaming, and other processing methods. Examples include everyday plastic stationery, toys, and building insulation materials, with wide applications in packaging, electronics, construction, and daily necessities.

[0003] Polystyrene discharge typically refers to the final product or intermediate product discharged from the production equipment after a series of reactions and processing during the polystyrene production process. After the polymerization reaction of polystyrene is completed, what is obtained is the polymer melt of polystyrene, which is a common form of polystyrene discharge. It has a certain degree of fluidity and plasticity and can be directly used for subsequent molding and processing, such as extruding it into various shapes of plastic products through an extruder.

[0004] However, in the actual production process, it is difficult to flexibly and precisely adjust the discharge speed of some existing polystyrene products according to the actual needs of the current production tasks. When the production process requires to speed up the discharge speed to increase the overall output at a certain time, or to slow down the discharge speed at another time to ensure the stability of product quality, the equipment cannot respond in a timely and effective manner, which seriously affects the smoothness and efficiency of production operations. Therefore, in order to address the above shortcomings, a polystyrene discharge control device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a polystyrene discharge control device, which aims to improve the problem that the discharge speed of some polystyrene products cannot be effectively controlled in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A polystyrene discharge control device includes a discharge frame, an discharge adjustment mechanism inside the discharge frame, and a quick-release mechanism on the front side of the discharge frame.

[0008] The discharge adjustment mechanism includes a guide ring, the outside of which is fixedly connected to the inside of the discharge frame. A conical ring is fixedly connected to the top of the guide ring, and a guide cone is slidably connected inside the guide ring. A limit groove is formed inside the guide cone, and an inclined rod is fixedly connected to the bottom of the guide cone. A spring is sleeved on the outside of the inclined rod. A protective ring is slidably connected inside the guide cone, and a limit ring is fixedly connected to the top of the protective ring. A drive assembly is provided on the right side of the discharge frame, and a guide frame is fixedly connected inside the guide ring.

[0009] As a further description of the above technical solution:

[0010] The drive assembly includes a cylinder, the left side of which is mounted on the outside right side of the discharge frame, a push rod is fixedly connected to the output end of the cylinder, and an inclined shaft is fixedly connected to the left side of the push rod.

[0011] As a further description of the above technical solution:

[0012] The quick-release mechanism includes multiple rotating disks, which are rotatably connected to the inside of the discharge frame. Connecting rods are fixedly connected to the front of the multiple rotating disks. Springs are sleeved on the outside of each of the multiple connecting rods. Sliding rings are slidably connected to the outside of each of the multiple connecting rods. Carding plates are fixedly connected to the front of each of the multiple connecting rods. Mounting plates are slidably connected to the outside of the multiple carding plates. Multiple slots are opened inside the mounting plates. A flow meter is fixedly connected inside the mounting plates.

[0013] As a further description of the above technical solution:

[0014] The bottom of the inclined rod contacts the left side of the inclined shaft, and the outer side of the protective ring is slidably connected to the inside of the limiting groove;

[0015] As a further description of the above technical solution:

[0016] The outer side of the limiting ring is slidably connected to the inside of the limiting groove, and the outer side of the guide cone is slidably connected to the inside of the conical ring;

[0017] As a further description of the above technical solution:

[0018] One end of the spring is fixedly connected to the bottom of the guide cone, and the other end of the spring is fixedly connected to the top of the guide frame.

[0019] As a further description of the above technical solution:

[0023] This utility model has the following beneficial effects:

[0024] 1. In this invention, when material flows in from the top of the conical ring, the cylinder is activated, serving as the power source for the drive assembly. This drives the push rod to displace the inclined shaft. The interaction between the inclined shaft and the inclined surface of the inclined rod converts the horizontal force into a vertical force, pushing the inclined rod and the guide cone upwards. At this time, the gap between the guide cone and the conical ring increases, accelerating the flow rate of the material through the gap; conversely, the flow rate decreases. This allows for precise control of the discharge rate, adapting to different application requirements and significantly improving production efficiency.

[0025] 2. In this utility model, when the flow meter needs to be disassembled, press the mounting plate backward so that the rear side of the mounting plate contacts the front side of the sliding ring, squeezing the sliding ring and causing the retaining plate to disengage from the inside of the mounting plate. Then, rotate the rotating plate to align the retaining plate with the slot opened inside the mounting plate. At this time, the second spring returns, and the retaining plate passes through the slot, thus realizing the disassembly of the flow meter. During installation, simply align the retaining plate with the slot, press the mounting plate so that the retaining plate passes through the slot and engages with the inside of the mounting plate. At the same time, the mounting plate squeezes the sliding ring, compressing the second spring. The whole process is simple to operate, requires no complicated tools, greatly saves the time of flow meter installation and disassembly, and improves the efficiency of equipment maintenance and repair.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1 to 3 This utility model provides an embodiment of a polystyrene discharge control device, including a discharge frame 1, which serves as the main supporting structure of the entire polystyrene discharge control device. A discharge adjustment mechanism 2 is installed inside the discharge frame 1, and a quick-release mechanism 3 is installed on the front side of the discharge frame 1. The discharge adjustment mechanism 2 includes a guide ring 21, which is externally fixedly connected to the inside of the discharge frame 1. A conical ring 22 is fixedly connected to the top of the guide ring 21, and a guide cone 23 is slidably connected inside the guide ring 21. When the guide cone 23 moves upward under the action of the drive component 29, it changes the gap between itself and the conical ring 22, thereby achieving precise control of the discharge rate. The external slidable connection of the guide cone 23 to the inside of the conical ring 22 allows the conical ring 22 to guide the polystyrene material flowing in from above to be evenly dispersed around the guide cone 23. When the material impacts the inner wall of the conical ring 22, it will naturally spread outwards according to its tilt angle, providing the prerequisite for controlling the discharge rate by adjusting the gap between the guide cone 23 and the conical ring 22.

[0035] The guide cone 23 has a limiting groove 24 inside, and an inclined rod 25 is fixedly connected to the bottom of the guide cone 23. When the inclined shaft 293 is displaced under the drive of the push rod 292, the inclined rod 25 will convert the horizontal force into a vertical force through the inclined contact between the two, thereby pushing the guide cone 23 to move upward. A spring 26 is sleeved on the outside of the inclined rod 25. One end of the spring 26 is fixedly connected to the bottom of the guide cone 23, and the other end of the spring 26 is fixedly connected to the top of the guide frame 210. When the guide cone 23 moves upward under the action of the drive assembly 29, the spring 26 will be stretched and store elastic potential energy. When the drive assembly 29 stops working or moves in the opposite direction, the spring 26 will release the stored elastic potential energy and pull the guide cone 23 back to the initial position, thereby realizing the automatic reset function of the discharge adjustment mechanism 2. The guide cone 23 has a protective ring 27 slidingly connected inside, and the outer side of the protective ring 27 is slidably connected inside the limiting groove 24. The top of the protective ring 27 is fixedly connected to a limiting ring 28, and the outer side of the limiting ring 28 is slidably connected inside the limiting groove 24. The design of the limiting groove 24 not only provides a precise sliding track for the protective ring 27 and the limiting ring 28, but also ensures the stability of the guide cone 23 during movement and prevents it from deviating or shaking.

[0036] A drive assembly 29 is provided on the outer right side of the discharge frame 1. The drive assembly 29 includes a cylinder 291, the left side of which is installed on the outer right side of the discharge frame 1. The cylinder 291 is the power source of the drive assembly 29. A push rod 292 is fixedly connected to the output end of the cylinder 291. An inclined shaft 293 is fixedly connected to the left side of the push rod 292. The bottom of the inclined rod 25 is in contact with the left side of the inclined shaft 293. When the push rod 292 pushes the inclined shaft 293 to move under the drive of the cylinder 291, the inclined surface of the inclined shaft 293 will interact with the inclined surface of the inclined rod 25, converting the horizontal thrust into a vertical force, thereby pushing the inclined rod 25 and the guide cone 23 to move upward. The guide ring 21 is fixedly connected to the guide frame 210 inside, the inclined rod 25 is slidably connected to the inside of the guide frame 210 outside, the bottom of the protective ring 27 is fixedly connected to the top of the guide frame 210, and the outside of the inclined rod 25 slides inside the guide frame 210, ensuring that it will not deviate or shake during the movement, thus ensuring the accuracy of force transmission.

[0037] Reference Figure 1 , Figure 4 and Figure 5The quick-release mechanism 3 includes multiple rotating disks 31, which are externally rotatably connected to the inside of the discharge frame 1. When the rotating disks 31 rotate, they drive the connecting rods 32 to rotate synchronously. Connecting rods 32 are fixedly connected to the front of each rotating disk 31. When the flow meter 38 is disassembled or installed, the connecting rods 32 move with the rotation of the rotating disks 31, simultaneously displacing the clamping plate 35 to achieve the fixing and loosening of the flow meter 38. Each connecting rod 32 is fitted with a second spring 33. When the installation plate 36 is pressed to disassemble or install the flow meter 38, the second spring 33 is compressed, storing elastic potential energy. When the operation is completed and the installation plate 36 is released, the second spring 33 releases the stored elastic potential energy, pushing the sliding ring 34 forward, thereby resetting the clamping plate 35 and automatically clamping and fixing the flow meter 38, ensuring that the flow meter 38 will not loosen during equipment operation. Multiple connecting rods 32 are slidably connected to the outside of sliding rings 34, and multiple connecting rods 32 are fixedly connected to the front side of clamping plates 35;

[0038] When it is necessary to disassemble the flow meter 38, press the mounting plate 36 backward to disengage the clamping plate 35 from the interior of the mounting plate 36. Then rotate the rotating disk 31 to align the clamping plate 35 into the interior of the slot 37. At this time, the spring 33 returns, and the clamping plate 35 passes through the slot 37, thus disassembling the flow meter 38. The mounting plate 36 is externally slidably connected to multiple clamping plates 35. The rear side of the mounting plate 36 contacts the front side of the sliding ring 34. Multiple slots 37 are opened inside the mounting plate 36, and the clamping plates 35 can be firmly clamped inside the slots 37 to prevent the flow meter 38 from loosening. The external side of the clamping plate 35 is slidably connected to the interior of the slots 37, and the flow meter 38 is fixedly connected inside the mounting plate 36. The flow meter 38 plays a key role in detecting the discharge rate in the entire equipment. It adopts a high-precision flow detection sensor, which can measure the discharge rate of polystyrene material in real time and accurately.

[0039] Working principle: When using this polystyrene discharge control equipment, when the material flows in from the top of the conical ring 22, the cylinder 291 is activated to drive the push rod 292 and the inclined shaft 293 to move. As the inclined shaft 293 moves, the inclined rod 25 moves upward due to the inclined surface design of the inclined shaft 293 and the inclined rod 25. This causes the guide cone 23 to move upward, which in turn allows the limiting ring 28 to slide inside the limiting groove 24. At this time, the spring 26 is stretched, which causes the guide cone 23 to move upward, increasing the gap between the guide cone 23 and the conical ring 22. This allows for the control of the discharge rate, which can be detected by the flow meter 38.

[0040] When the flow meter 38 needs to be replaced, press the mounting plate 36 backward to disengage the clamping plate 35 from the inside of the mounting plate 36. Then rotate the clamping plate 35 so that the rotating plate 31 rotates inside the discharge frame 1, aligning the clamping plate 35 with the inside of the slot 37. This will cause the second spring 33 to rebound, allowing the clamping plate 35 to pass through the inside of the slot 37, thus enabling the disassembly of the flow meter 38. When the flow meter 38 needs to be installed, simply align the clamping plate 35 with the inside of the slot 37, and then press the mounting plate 36 to allow the clamping plate 35 to pass through the inside of the slot 37. This will cause the mounting plate 36 to press the sliding ring 34, causing the sliding ring 34 to slide outside the connecting rod 32. At the same time, the second spring 33 will be compressed, allowing the clamping plate 35 to engage with the inside of the mounting plate 36, thus enabling the quick installation of the flow meter 38.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
