Description

Technical Field

[0001] This utility model relates to the field of material suction machine technology, and in particular to a novel material suction machine for the production of thermoplastic polyurethane granules. Background Technology

[0002] Thermoplastic polyurethane granules have wide applications in many industrial fields, playing a key role in the manufacture of high-performance plastic products and automotive parts. The material feeder in the production of new thermoplastic polyurethane granules plays a crucial role in the entire production process. It is responsible for the accurate and efficient transportation and handling of granules or related materials during production, ensuring the continuity of production. During granule production, materials in different states are generated, and the material feeder needs to accurately collect these materials. Whether it is small, dispersed granules or residue generated during production, they all need to be properly handled to ensure a clean production environment and the rational use of resources. This is of great significance for improving the production quality and efficiency of granules.

[0003] Traditional thermoplastic polyurethane granule production suction machines typically use flange connections for their piping. Flange connections require numerous bolts and nuts for tightening, necessitating precise alignment of bolt holes during installation, making the process cumbersome and time-consuming. Regarding the suction function, they often rely on a single drive motor connected to the piping, with suction power controlled by adjusting the motor's power to pick up granules and residues. This method lacks targeted, localized suction adjustment, resulting in poor performance for residues in different locations and with varying accumulation states. Furthermore, the motor's prolonged operation at high or inappropriate power levels can easily lead to equipment wear and tear.

[0004] Currently, the assembly of pipelines for polyurethane granule production suction machines is complicated and consumes a lot of time and manpower. For example, flange connections require workers to tighten each bolt individually and ensure that the tightening of each bolt is uniform, otherwise leakage problems may occur. This complicated assembly process greatly slows down the overall progress during large-scale production or equipment maintenance and pipeline replacement, resulting in the equipment not being put into use in a timely manner, seriously affecting production efficiency and increasing production costs. Utility Model Content

[0007] A novel thermoplastic polyurethane granule production material suction machine includes a support plate, a support assembly on the top of the support plate for supporting the equipment, a power assembly on the top of the support plate for providing suction to the equipment, a control assembly on the top of the support plate for displaying and controlling equipment parameters, and a filter assembly on the side of the control assembly for filtering impurities during material suction.

[0008] The filtration assembly includes a filter barrel disposed on the side wall of the control assembly. An air inlet pipe is fixedly connected to the side wall of the filter barrel. A threaded seat is fixedly connected to one end of the side wall of the air inlet pipe. Multiple balls are slidably connected to the inner wall of the threaded seat. The balls are distributed circumferentially on the inner wall of the threaded seat. A movable ring is slidably connected to the outer wall of the threaded seat. A connecting seat is slidably connected to the inner wall of the threaded seat. A groove is formed on the outer wall of the connecting seat. A connecting pipe is fixedly connected to the outer wall of the connecting seat. A feeding assembly is provided at one end of the connecting pipe. The assembly is used to suck up materials.

[0009] Optionally, the support assembly includes a support arm, the bottom of which is fixedly connected to the top of the support plate. The support arm is distributed on the left and right sides of the support plate. A plurality of casters are fixedly connected to the bottom of the support plate, and the casters are distributed in an array on the bottom of the support plate.

[0010] Optionally, the power assembly includes a base, the bottom of which is fixedly connected to the top of the support plate, a drive motor fixedly connected to the top of the base, an air suction pipe fixedly connected to the output end of the drive motor, and one end of the air suction pipe fixedly connected to the top of the filter barrel.

[0011] Optionally, the control component includes a console, the side wall of which is fixedly connected to the side wall of the support arm, a connecting block is fixedly connected to the side wall of the console, a plurality of connecting rings are fixedly connected inside the connecting block, and the inner wall of the connecting rings is fixedly connected to the outer wall of the filter bucket.

[0012] Optionally, the feeding assembly includes a feeding cup, a connecting tube slidably connected to the top of the feeding cup, and multiple supports fixedly connected to the bottom of the feeding cup. The supports are distributed in a circumferential shape at the bottom of the feeding cup, and a material bucket is fixedly connected to the bottom of the supports.

[0013] Optionally, a feeding pipe is slidably connected to the side wall of the feeding cup, a partition is fixedly connected to one end of the feeding pipe, and a suction device is fixedly connected to the bottom of the partition.

[0014] Optionally, a small motor is fixedly connected inside the partition, and a drive gear is fixedly connected to the output end of the small motor. The drive gear is rotatably connected to the inner wall of the partition. A driven rack one and a driven rack two are provided on the upper and lower sides of the drive gear, and the drive gear meshes with the driven rack one and the driven rack two.

[0015] Optionally, a connecting plate is fixedly connected to one side wall of the driven rack, a movable door is fixedly connected to the connecting plate, the bottom of the driven rack is fixedly connected to the top of the movable door, a slide rail is fixedly connected to the inner wall of the partition, and the movable door is slidably connected to the inner wall of the slide rail.

[0016] The above-mentioned technical solutions of the novel thermoplastic polyurethane granule production suction machine provided in this embodiment of the utility model have at least one of the following technical effects:

[0017] 1. In this utility model, the connecting seat at one end of the connecting pipe is first inserted into the threaded seat of the air inlet pipe. The ball bearings in the threaded seat slide into the groove of the connecting seat to achieve initial fixation. Then, the movable ring on the outer wall of the threaded seat is rotated. Its rotational displacement will further restrict the movement space of the ball bearings, thus locking the connecting seat. This operation is repeated for multiple pipelines of the equipment, which can quickly and easily fix and assemble the pipelines. This solves the problem of complex and time-consuming assembly of traditional pipelines, improves the equipment assembly efficiency, and reduces production delays caused by complex assembly.

[0018] 2. In this utility model, the small motor inside the partition drives the drive gear to rotate, causing the driven racks on both sides to move relative to each other, thereby moving the movable door. In this way, the residual material can be sucked up without adjusting the total power of the drive motor, achieving a high-efficiency residual material suction effect. This solves the problem of incomplete material suction caused by improper power adjustment, improves the residual material suction efficiency and the stability of the suction machine, and reduces equipment maintenance costs and material waste.

[0031] Reference Figure 1 - Figure 4This utility model provides an embodiment of a novel thermoplastic polyurethane granule production suction machine, comprising a support plate 1, a support assembly on the top of the support plate 1 for supporting the equipment, a power assembly on the top of the support plate 1 for providing suction to the equipment, a control assembly on the top of the support plate 1 for displaying and controlling equipment parameters, and a filter assembly on the side of the control assembly for filtering impurities during material suction. The filter assembly includes a filter barrel 9, which is filled with high-efficiency filter materials such as filter screens and filter cotton. The pore size and density of these filter materials are carefully selected to effectively intercept impurity particles in the polyurethane granules, such as dust and debris, preventing them from entering the motor and causing electrical problems. In case of machine malfunction, the filter cartridge 9 is located on the side wall of the control component. An air inlet pipe 11 is fixedly connected to the side wall of the filter cartridge 9. A threaded seat 19 is fixedly connected to one end of the side wall of the air inlet pipe 11. Multiple balls 21 are slidably connected to the inner wall of the threaded seat 19. The balls 21 are distributed circumferentially on the inner wall of the threaded seat 19. This distribution ensures that a uniform restraining force is applied to the connecting seat 22 in all directions. A movable ring 20 is slidably connected to the outer wall of the threaded seat 19. The inner wall of the movable ring 20 is tightly fitted to the outer wall of the threaded seat 19, achieving relative rotation through a threaded connection. Its inner surface has a raised structure. When the movable ring 20 rotates, the raised structure gradually approaches the balls 21, thereby reducing the movable space of the balls 21. A connecting seat 21 is slidably connected to the inner wall of the threaded seat 19. The connecting seat 22, as one of the key components of the connection, is made of high-strength stainless steel, which is strong and durable. The outer wall of the connecting seat 22 is finely machined to ensure a tight fit with the inner wall of the threaded seat 19. A groove 23 is formed on the outer wall of the connecting seat 22. The groove 23 is an important structure for achieving connection locking. The size and depth of the groove 23 form a good matching relationship with the ball 21. A connecting pipe 12 is fixedly connected to the outer wall of the connecting seat 22. One end of the connecting pipe 12 is equipped with a feeding component for picking up materials. The support component includes a support arm 3. The bottom of the support arm 3 is fixedly connected to the top of the support plate 1. The support arms 3 are distributed on the left and right sides of the support plate 1. Multiple casters 2 are fixedly connected to the bottom of the support plate 1 in an array. The power assembly, distributed at the bottom of the support plate 1, includes a base 4, whose bottom is fixedly connected to the top of the support plate 1. A drive motor 5 is fixedly connected to the top of the base 4, serving as the power source for suction. An air intake pipe 10 is fixedly connected to the output end of the drive motor 5. The motor's output shaft is connected to the air intake pipe 10 via a coupling to ensure stable power transmission. One end of the air intake pipe 10 is fixedly connected to the top of the filter canister 9. The control assembly includes a control console 6, which clearly displays various parameters of the equipment, such as suction strength and motor speed. It is electrically connected to the drive motor 5 via an internal circuit board and control program. Operators can set the operating parameters of the drive motor 5 on the control console 6. The side wall of the control console 6 is fixedly connected to the side wall of the support arm 3.A connecting block 7 is fixedly connected to the side wall of the control console 6. Multiple connecting rings 8 are fixedly connected inside the connecting block 7. The inner wall of the connecting rings 8 is fixedly connected to the outer wall of the filter bucket 9. The feeding assembly includes a feeding cup 13, which is a place for temporary storage and dispersion of materials. It is made of transparent plastic material, making it easy for operators to observe the state of the materials. It has a conical guide structure inside, which allows the materials to be evenly dispersed after entering. A connecting pipe 12 is slidably connected to the top of the feeding cup 13. Multiple supports 14 are fixedly connected to the bottom of the feeding cup 13. The supports 14 are distributed circumferentially at the bottom of the feeding cup 13. A material bucket 15 is fixedly connected to the bottom of the supports 14. The material bucket 15 serves as a container for storing materials, and its capacity is designed according to production needs. The bottom of the feed cup 13 is typically designed with a discharge port for convenient subsequent material processing. A feed pipe 16 is slidably connected to the side wall of the feed cup 13. One end of the feed pipe 16 is fixedly connected to a baffle 17, a component used to control the amount of material sucked in. The shape and size of the baffle 17 are designed according to the specifications of the feed pipe 16 and the material suction requirements, ensuring a tight connection with both the feed pipe 16 and the suction device 18. The bottom of the baffle 17 is fixedly connected to the suction device 18, which is the component that directly contacts the polyurethane granules and sucks up the material. Its suction port is typically made of soft rubber or silicone material, which has good flexibility and sealing properties, allowing it to fit tightly against the bottom of the material trough to prevent air leakage and ensure effective material suction.

[0032] Specifically, when using this suction machine, the operator first needs to perform a simple assembly of the equipment's piping. This process is crucial for the normal operation of the equipment. First, the operator inserts the connecting seat 22 at one end of the connecting pipe 12 into the threaded seat 19 of the air inlet pipe 11. When the connecting seat 22 is inserted, the ball bearing 21, under its own weight and the insertion force of the connecting seat 22, rolls along the inner wall of the threaded seat 19 and accurately slides into the groove 23, thus achieving initial positioning and fixation. Then, the operator rotates the movable ring 20 on the outer wall of the threaded seat 19. During rotation, the movable ring 20 rotates along the axial direction of the threaded seat 19. As the rotation angle increases, the restraining effect on the ball bearing 21 becomes stronger, ultimately locking the connecting seat 22 firmly into the threaded seat 19. This method is repeated for multiple pipes on the equipment, achieving a quick and easy fixation and assembly of the equipment's piping. This connection method is convenient and fast, ensuring the stability and sealing of the pipe connection, reducing suction loss or material loss due to loosening of the pipes during the suction process. To prevent material leakage and other issues, after assembly, the partition 17 and the suction device 18 are first placed into the material trough. Then, the drive motor 5 is started by controlling the control panel 6 to generate suction. When the drive motor 5 starts, its internal motor rotor rotates at high speed, driving the air flow in the suction pipe 10, thereby generating suction. At this time, the suction is transmitted to the filter barrel 9 through the suction pipe 10, and then to the connecting pipe 12 through the air inlet pipe 11 on the outer wall of the filter barrel 9. One end of the air inlet pipe 11 is fixedly connected to the side wall of the filter barrel 9, and the other end is connected to the connecting pipe 12. The material is transferred from the feed tube 12 to the inside of the feeding cup 13 and simultaneously to the feed pipe 16 on the outer wall of the feeding cup 13. The suction device 18 at the bottom of the feed pipe 16 then adsorbs the polyurethane granules. The adsorbed granules enter the inside of the feeding cup 13 through the feed pipe 16 and are dispersed inside the feeding cup 13 before falling into the material bucket 15, awaiting processing in the next process. Throughout the material suction process, all components work together to ensure that the polyurethane granules can be efficiently and stably drawn from the material tank into the material bucket 15, providing high-quality raw materials for subsequent production processes.

[0033] Reference Figure 5A small motor 24 is fixedly connected inside the partition 17. The small motor 24 serves as the drive component and the power source for the entire residual material suction operation, providing stable power output. A drive gear 25 is fixedly connected to the output end of the small motor 24. The drive gear 25 has smooth and high-precision teeth, ensuring tight and stable meshing with driven rack 1 26 and driven rack 28. The drive gear 25 is rotatably connected to the inner wall of the partition 17. Driven rack 1 26 and driven rack 28 are arranged on the upper and lower sides of the drive gear 25, with high meshing precision to ensure accurate power transmission. The drive gear 25 meshes with driven rack 1 26 and driven rack 28. A connecting plate 27 is fixedly connected to the side wall of driven rack 1 26, serving as a connection between the driven rack 1 26 and driven rack 28. The intermediate component between the driven rack 26 and the movable door 29 is made of steel plate, which has good strength and rigidity. The connecting plate 27 is fixed to the driven rack 26 and the movable door 29 by welding to ensure that there will be no loosening during the movement. The movable door 29 is fixedly connected to the connecting plate 27. The movable door 29 is composed of metal plate and sealing rubber. The sealing rubber is pasted on the edge of the movable door 29. The sealing rubber has good elasticity and sealing performance. When the movable door 29 is closed, it can be tightly fitted to the inner wall of the partition 17 to prevent air leakage and ensure the normal operation of the suction system. The bottom of the driven rack 28 is fixedly connected to the top of the movable door 29. The inner wall of the partition 17 is fixedly connected to the slide rail 30. The movable door 29 is slidably connected to the inner wall of the slide rail 30.

[0034] Specifically, during the material feeding process, when encountering residual polyurethane particles at the bottom, the partition 17 begins to function. First, the small motor 24 drives the drive gear 25 to rotate. Driven by the small motor 24, the drive gear 25 rotates around its axis within the inner wall of the partition 17. Its rotation direction is determined by the rotation direction of the small motor 24, and its rotation speed is proportional to the speed of the small motor 24. The rotation of the drive gear 25 causes relative displacement of the driven racks 26 and 28 on either side. Under the action of the drive gear 25, the driven racks 26 and 28 move along a straight line perpendicular to the tangent of the gear teeth. Due to the rotation of the drive gear 25, the driven racks 26 and 28... The rack 28 moves in opposite directions. This relative displacement is key to the opening and closing of the movable door 29. Driven by the driven rack 1 26 and the driven rack 28, the movable door 29 slides along the slide rail 30 on the inner wall of the partition 17. This allows for the collection of residual material without adjusting the total power of the drive motor 5, thus achieving efficient collection of residual material. This design enables the suction machine to cleverly collect residual polyurethane particles at the bottom through local structural adjustments, avoiding problems such as excessive suction causing damage to the material or affecting the stability of the entire suction system caused by adjusting the total power of the drive motor 5. This improves the efficiency and quality of material collection and ensures the continuity and stability of the production process.

[0035] Working Principle: When using this suction feeder, the operator first needs to perform a simple assembly of the equipment's piping. First, the operator inserts the connecting seat 22 at one end of the connecting pipe 12 into the threaded seat 19 of the air inlet pipe 11. At this time, multiple balls 21 inside the threaded seat 19 slide into the groove 23 of the connecting seat 22, forming a preliminary fixation. Then, the operator rotates the movable ring 20 on the outer wall of the threaded seat 19. As the movable ring 20 rotates and shifts, it further restricts the movement space of the balls 21, thus locking the connecting seat 22. This method is used to perform the same operation on multiple pipes on the equipment, achieving a quick and easy fixation and assembly of the equipment's piping. After assembly, the separator 17 and the suction feeder 18 are placed into the material trough. Then, the control console 6 controls the drive motor 5 to start working and generate suction. At this time, the suction is transmitted to the filter bucket 9 through the suction pipe 10. Air is conveyed from the inlet pipe 11 on the outer wall of the filter barrel 9 to the connecting pipe 12, and then from the connecting pipe 12 to the inside of the feeding cup 13. At the same time, it is conveyed to the feed pipe 16 on the outer wall of the feeding cup 13. The polyurethane particles are then adsorbed by the suction device 18 at the bottom of the feed pipe 16. The adsorbed particles enter the inside of the feeding cup 13 through the feed pipe 16 and are dispersed inside the feeding cup 13 before falling into the material bucket 15, waiting for the next process. During the suction process, when the remaining polyurethane particles at the bottom are encountered, the small motor 24 on the inner wall of the partition 17 drives the drive gear 25 to start rotating. The rotation of the drive gear 25 causes the driven rack 1 26 and driven rack 28 on both sides to move relative to each other. The displacement of driven rack 1 26 and driven rack 28 causes the movable door 29 to move. This achieves the effect of efficiently sucking up the residual material without adjusting the total power of the drive motor 5.
