A polyurethane elastomer material processing apparatus

Abstract

This invention discloses a polyurethane elastomer material processing device, relating to the field of polyurethane material technology. Both sides of the conveyor belt are rotatably connected to baffles. A mixing chamber is fixedly connected to the outer surface of each baffle, and a drying chamber is fixedly connected to the end of each baffle. A drying device is provided at the upper end of the inner surface of the drying chamber, and a drying unit is provided at the outer surface of the drying chamber. An alignment device is provided inside each baffle. In use, the output airflow, due to its own reaction force, pushes the fan and the upper air inlet block to slide along the groove on the inner surface of the drying chamber. During this sliding process, the contact block gradually contacts the collision blocks on both sides, causing the fan and the air inlet block to rotate. Therefore, the fan reciprocates while continuously expelling hot air, allowing it to fully dry and cure the polyurethane elastomer material inside the mold.

Description

Technical Field

[0001] This invention relates to the field of polyurethane materials technology, and in particular to a polyurethane elastomer material processing apparatus. Background Technology

[0002] Polyurethane elastomers are elastic materials widely used in industrial and consumer products. They have excellent physical and chemical properties and are made of polyurethane polymers. Their structure consists of polyether, polyester or polyether ester segments and crosslinking agents.

[0003] In existing technologies, raw materials are often prepared and then injected into molds by mechanical stirring or extrusion, and then cured by drying.

[0004] However, in actual use, existing drying methods often use hot air drying in a sealed environment. As a result, there is always evaporated moisture inside the sealed chamber during the drying process, which makes the air humidity high. Expelling the hot air inside causes the overall heat loss to be rapid, which requires additional energy to heat up the inside of the drying chamber. Therefore, the overall drying and curing cost is high, making it inconvenient to promote its use. In view of this, we propose a polyurethane elastomer material processing device. Summary of the Invention

[0005] The main objective of this invention is to provide a polyurethane elastomer material processing apparatus that solves the problem mentioned in the background art, where during the drying process, there is always evaporated moisture inside the sealed chamber, resulting in high air humidity. Expelling the hot air from inside causes rapid heat loss, thus requiring additional energy to heat the interior of the drying chamber.

[0009] Preferably, the alignment device includes a fixed shaft, an arc-shaped block is fixedly connected to the outer surface of the fixed shaft, a positioning rod is slidably connected to the upper end of the inner surface of the baffle, an adjusting rod is slidably connected to the inner surface of the baffle, and a push plate is fixedly connected to the end of the adjusting rod.

[0010] Preferably, there are two sets of baffles, and the two sets of baffles are symmetrically distributed with the center line of the conveyor belt as the axis of symmetry. Multiple sets of rectangular protrusions are provided on the outer surface of the baffles. The upper surface of the mixing bin is connected to the feeding pipe. Through holes are opened on both sides of the drying bin. A rectangular groove is opened at the upper end of the inner surface of the drying bin.

[0011] Preferably, the upper and lower ends of the fan are the air inlet and the air outlet, respectively. The upper surface of the fan is provided with an arc-shaped groove, and the lower end of the outer arc surface of the air inlet block is provided with a rectangular protrusion. The air inlet block is hollow inside and its lower end is connected to the air inlet of the fan.

[0012] Preferably, the outer arc surface of the air inlet block is connected to the connecting block via a flexible hose, the lower end of the air outlet is configured as a flat-topped pyramid, and two sets of collision blocks are provided, with the two sets of collision blocks symmetrically distributed about the center line of the drying chamber.

[0013] Preferably, the drying oven has through holes on both sides, and a rectangular through hole on the lower surface of the drying oven. The cross-sectional areas of the upper fixing plate and the lower connecting plate are both larger than the cross-sectional area of ​​the through hole at the lower end of the drying oven.

[0014] Preferably, the lower surface of the upper fixing plate is provided with multiple sets of rectangular protrusions, the upper surface of the lower connecting plate is provided with a magnet, the upper surface of the lower connecting plate is provided with multiple sets of rectangular protrusions, and the outer surface of the drying box is fixedly connected to the drying chamber.

[0015] Preferably, the outer surface of the fixed shaft is rotatably connected to the baffle, the arc surface of the arc block is elastically connected to the push plate by a spring, the outer arc surface of the positioning rod is provided with an annular protrusion, the upper end of the inner surface of the baffle is provided with a cylindrical sliding groove, the protrusion of the outer arc surface of the positioning rod is elastically connected to the baffle by a spring, the inner surface of the baffle is provided with a longitudinal through hole, and the upper surface of the adjusting rod is provided with multiple sets of cylindrical grooves.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] (1) When the polyurethane elastomer material processing device is in use, the output wind force will also push the fan and the air inlet block above to slide in one direction along the sliding groove on the inner surface of the drying chamber due to its own reaction force. During the sliding process, the contact block on the outer surface of the fan will gradually contact the collision blocks on both sides. At this time, the collision block will push the contact block and enable it to drive the fan to rotate. At the same time, the rotation amplitude of the fan will also be limited by the upper baffle, so that after the rotation is completed, the air outlet will rotate 90°. At this time, the wind force discharged from the air outlet will push the fan to move in the opposite direction. Since there are two sets of collision blocks and the two sets of collision blocks are symmetrically distributed, the fan will reciprocate in the process of continuously discharging hot air, and enable it to fully dry and cure the polyurethane elastomer material inside the mold.

[0018] (2) When the polyurethane elastomer material processing device is in use, the hot air containing water vapor in the drying chamber will enter the circulation pipe and gradually enter the drying box along the circulation pipe. At this time, the drying plate inside the drying box will absorb the water vapor in the hot air, thereby reducing the overall humidity inside the drying chamber. At the same time, when the drying plate absorbs more water, its own weight will increase due to water absorption. At this time, the drying plate will increase the pressure on the lower connecting plate below. When the drying plate absorbs more water, the lower connecting plate will detach from the suction between it and the drying box due to the pressure above, so that the upper fixed plate can slide down to cover the drying box and maintain the internal sealing state of the circulation pipe. People can easily replace the drying plate after the lower connecting plate falls off.

[0019] (3) When the mold moves on the upper surface of the conveyor belt, the polyurethane elastomer material processing device will be squeezed by the arc blocks on both sides. At this time, the arc blocks will push the mold as a whole towards the center of the conveyor belt due to their own elastic deformation ability and the elastic force of the spring. At the same time, when using molds of different shapes and sizes, people can lift the positioning rod to move it away from the adjusting rod. At this time, people can push the adjusting rod to move it inside the baffle. At the same time, as the adjusting rod moves, the push plate will also move and can drive the arc block and the fixed shaft to rotate as a whole through the elastic force of the spring, thereby preventing it from causing excessive resistance to the mold and causing the mold to stop on the upper surface of the conveyor belt. As a result, when the mold is driven to move on the conveyor belt, it is not easy to produce a large deviation. Attached Figure Description

Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this invention.

[0031] Please see Figure 1-6 The present invention provides a technical solution: a polyurethane elastomer material processing device, including a conveyor belt 7, baffles 1 rotatably connected to both sides of the conveyor belt 7, a mixing bin 6 fixedly connected to the outer surface of the baffles 1, a drying bin 5 fixedly connected to the end of the baffles 1, a drying device 2 provided at the upper end of the inner surface of the drying bin 5, a drying device 3 provided at the outer surface of the drying bin 5, and an alignment device 4 provided inside the baffles 1.

[0032] The drying device 2 includes a fan 204, an air inlet block 202 fixedly connected to the upper end of the fan 204, the upper end of the air inlet block 202 being slidably connected to the drying chamber 5, an air outlet 205 fixedly connected to the lower end of the fan 204, a collision block 201 fixedly connected to the upper end of the inner surface of the drying chamber 5, a connecting block 203 fixedly connected to the right side of the inner surface of the drying chamber 5, a baffle 206 fixedly connected to the upper surface of the fan 204, and a contact block 207 fixedly connected to the end of the fan 204 away from the air outlet 205.

[0033] Specifically, two sets of baffles 1 are provided, and the two sets of baffles 1 are symmetrically distributed about the center line of the conveyor belt 7. Multiple sets of rectangular protrusions are provided on the outer surface of the baffles 1, allowing them to be fixedly connected to the mixing bin 6 via these protrusions. A feed pipe is connected to the upper surface of the mixing bin 6, allowing raw materials to be injected into the mixing bin 6 for mixing. Through holes are provided on both sides of the drying bin 5, allowing molds to enter and exit through these holes. In actual use, PVC curtains need to be installed at the through holes on both sides of the drying bin 5 to prevent heat loss from inside the drying bin 5. A rectangular groove is provided at the upper end of the inner surface of the drying bin 5, allowing the air inlet block 202 to slide within the groove. The upper and lower ends of the blower 204 are the air inlet and air outlet, respectively. The upper surface of 204 is provided with an arc-shaped groove, so that the baffle 206 can be located in it and rotate. The lower end of the outer arc surface of the air inlet block 202 is provided with a rectangular protrusion, so that the rotation range of the fan 204 can be limited. The air inlet block 202 is hollow inside and its lower end is connected to the air inlet of the fan 204, so that it can transmit air force. The outer arc surface of the air inlet block 202 is connected to the connecting block 203 through a flexible hose, so that the flexible hose will not obstruct the movement of the air inlet block 202 when it moves. The lower end of the air outlet 205 is set as a flat-topped pyramid shape. There are two sets of collision blocks 201, and the two sets of collision blocks 201 are symmetrically distributed about the center line of the drying chamber 5. So that the contact block 207 can continuously change the direction of the fan 204 by contacting the collision blocks 201 on both sides.

[0034] In this embodiment of the invention, the drying device 3 includes a drying chamber 302. An upper fixing plate 301 is slidably connected to the inner surface of the drying chamber 302. A lower connecting plate 305 is fixedly connected to the lower surface of the upper fixing plate 301. A drying plate 304 is placed on the upper surface of the lower connecting plate 305. Both sides of the drying chamber 302 are connected to circulation pipes 303. A connecting block 203 is fixedly connected to one end of the circulation pipe 303 away from the drying chamber 302.

[0035] Specifically, the drying chamber 302 has through holes on both sides, allowing it to connect with the circulation pipe 303. A rectangular through hole is located on the lower surface of the drying chamber 302, allowing the upper fixing plate 301 to press the lower connecting plate 305 downwards. The cross-sectional areas of both the upper fixing plate 301 and the lower connecting plate 305 are larger than the cross-sectional area of ​​the through hole at the lower end of the drying chamber 302, preventing the upper fixing plate 301 from detaching from the drying chamber 302 during sliding. Multiple sets of rectangular protrusions are provided on the lower surface of the upper fixing plate 301, allowing it to connect with the lower connecting plate 305. A magnet is provided on the upper surface of the lower connecting plate 305, and the lower surface of the drying chamber 302 is made of magnetic metal, allowing the lower connecting plate 305 to adhere to the lower surface of the drying chamber 302 upon contact. Multiple sets of rectangular protrusions are provided on the upper surface of the lower connecting plate 305, providing fixed support for the drying plate 304. The outer surface of the drying chamber 302 is fixedly connected to the drying chamber 5.

[0036] In this embodiment of the invention, the alignment device 4 includes a fixed shaft 402, an arc-shaped block 401 fixedly connected to the outer surface of the fixed shaft 402, a positioning rod 405 slidably connected to the upper end of the inner surface of the baffle 1, an adjusting rod 404 slidably connected to the inner surface of the baffle 1, and a push plate 403 fixedly connected to the end of the adjusting rod 404.

[0037] Specifically, the outer surface of the fixed shaft 402 is rotatably connected to the baffle 1. The arc surface of the arc block 401 is elastically connected to the push plate 403 via a spring. The arc block 401 is a metal spring sheet, thus giving it a certain elastic deformation capability. The outer arc surface of the positioning rod 405 is provided with an annular protrusion, thus enabling it to connect to the spring. The upper end of the inner surface of the baffle 1 is provided with a cylindrical groove, thus allowing the positioning rod 405 to slide inside the baffle 1. The protrusion on the outer arc surface of the positioning rod 405 is elastically connected to the baffle 1 via a spring, thus allowing the positioning rod 405 to be pushed downward and inserted into the adjusting rod 404 by the spring force when the positioning rod 405 is released, thereby limiting its position. The inner surface of the baffle 1 is provided with a longitudinal through hole, thus allowing the adjusting rod 404 to slide inside the baffle 1. The upper surface of the adjusting rod 404 is provided with multiple sets of cylindrical grooves, thus allowing the positioning rod 405 to limit its position when inserted into the upper end of the adjusting rod 404.

[0038] During operation (or use), the material to be mixed needs to be placed into the mixing bin 6 through the pipe at the top of the mixing bin 6. At this time, the mold can be placed on the upper surface of the conveyor belt 7 according to the actual processing requirements. The conveyor belt 7 can be driven to rotate as a whole by an external drive device, so that the mold can be transported to the lower end of the mixing bin 6. At this time, the mixing bin 6 can be used to inject material into the mold below.

[0039] Simultaneously, as the mold moves on the upper surface of the conveyor belt 7, it will be squeezed by the arc blocks 401 on both sides. At this time, the arc blocks 401 will push the mold as a whole towards the center of the conveyor belt 7 due to their own elastic deformation ability and the spring force. At the same time, when using molds of different shapes and sizes, people can lift the positioning rod 405 to move it away from the adjusting rod 404. Then, people can push the adjusting rod 404 to move it inside the baffle 1. At the same time, as the adjusting rod 404 moves, the push plate 403 will also move and can drive the arc blocks 401 and the fixed shaft 402 to rotate as a whole through the spring force, thereby preventing excessive resistance to the mold and causing the mold to stop on the upper surface of the conveyor belt 7. As a result, when the mold is driven to move on the conveyor belt 7, it is not easy to produce a large deviation.

[0040] Simultaneously, when the material filling in the mold of this device is completed, the conveyor belt 7 will transport the mold containing polyurethane elastomer material to the drying chamber 5 through its own operation. At this time, the blower 204 can be started to continuously operate and deliver hot air through the air outlet 205 to the upper surface of the mold, thereby drying the material. At the same time, when the blower 204 outputs air force, the output air force will also push the blower 204 and the air inlet block 202 above it to slide in one direction along the slide groove on the inner surface of the drying chamber 5 due to its own reaction force. During its sliding process, the contact block 207 on the outer surface of the blower 204 will gradually contact the two sides of the contact block. When the impact block 201 is engaged, it will push the contact block 207 and cause the fan 204 to rotate. At the same time, the rotation amplitude of the fan 204 will be limited by the upper stop block 206, so that after the rotation is completed, the air outlet 205 will rotate 90°. At this time, the air force discharged from the air outlet 205 will push the fan 204 to move in the opposite direction. Since there are two sets of impact blocks 201, and the two sets of impact blocks 201 are symmetrically distributed, the fan 204 will reciprocate while continuously discharging hot air, and can fully dry and cure the polyurethane elastomer material inside the mold.

[0041] Furthermore, during the operation of the fan 204, airflow will be continuously supplied into the drying chamber 5. Simultaneously, as the fan 204 supplies airflow, the hot air containing moisture inside the drying chamber 5 will enter the circulation pipe 303 and gradually flow into the drying box 302. At this time, the drying plate 304 inside the drying box 302 will absorb the moisture in the hot air, thereby reducing the overall humidity inside the drying chamber 5. When the drying plate 304 absorbs a lot of moisture, its own weight will increase due to the water absorption. This will increase the pressure of the drying plate 304 on the lower connecting plate 305 below. When the drying plate 304 absorbs a lot of water, the lower connecting plate 305 will disengage from the drying box 302 due to the pressure from above, allowing the upper fixing plate 301 to slide downwards to cover the drying box 302 and maintain the internal sealing of the circulation pipe 303. After the lower connecting plate 305 falls off, the upper drying plate 304 can be easily replaced.

[0042] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
