Description

Technical Field

[0001] This utility model relates to the field of polyurethane resin preparation, and more specifically, it relates to a feeding device for polyurethane resin preparation. Background Technology

[0002] Polyurethane comes in various forms, including soft, semi-rigid, rigid, and elastomers, and can replace materials such as rubber, nylon, and plastics. It is widely used in industries such as building materials, aerospace, and automotive machinery.

[0003] A polyurethane resin processing and loading device is disclosed in patent CN220997036U, including a base, a weighing mechanism mounted on the top of the base, and brackets symmetrically distributed on both sides of the weighing mechanism fixedly installed on the top of the base. A mounting frame is fitted at the end of the brackets, and an arc-shaped plate is fixedly connected to the inner side of the mounting frame. A storage tank is fitted between the two sets of arc-shaped plates. Uniformly distributed sleeves are fixedly fitted on the arc-shaped plates. Uniformly distributed movable rods are fixedly connected to the outer side of the storage tank, and a vibration motor is installed on the outer side of the storage tank. The movable rods are movably fitted in the sleeves.

[0004] The loading device in the above scheme, through the combined use of a vibrating motor, a sleeve, a movable rod, and a spring, enables the vibrating motor on the storage tank to start and generate vibration during the loading process of the polyurethane resin processing loading device. After being affected by the vibration, the storage tank drives the movable rod to extend and retract within the sleeve, compressing the spring. After being compressed and deformed, the spring drives the entire storage tank to return to its original position under its own elastic force, thereby increasing the vibration frequency of the storage tank and preventing raw materials from adhering to the inner wall of the storage tank, thus avoiding waste of raw materials. However, this device will cause a lot of polyurethane resin to adhere to the stirring mechanism set inside the storage tank, which will lead to waste of raw materials.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] To address the shortcomings of existing technologies, the present invention aims to provide a feeding device for preparing polyurethane resin. The device can stir the raw materials in the feeding tank through a stirring component and squeeze out the raw materials in the feeding tank through a discharging component, thereby avoiding a large amount of raw materials remaining on the stirring component and reducing raw material waste.

A threaded rod is fixedly connected to the output shaft of the motor. The threaded rod is rotatably connected to the feeding barrel. A stirring component for stirring raw materials is provided on the threaded rod. An outlet component for controlling the discharge is provided on the feeding barrel.

[0008] The present invention is further configured such that: the stirring assembly includes a stirring disc threadedly connected to a threaded rod and a limiting rod slidably connected to the stirring disc; the stirring disc has several through grooves; and the two ends of the limiting rod are respectively fixedly connected to a support rod and the bottom side of the discharge bucket.

[0009] The present invention is further configured such that: the discharge assembly includes a pusher plate slidably connected inside the discharge bucket, several blocking rods fixedly connected to the bottom side of the pusher plate, a magnetic ring one fixedly connected to the pusher plate, and a magnetic ring two fixedly connected to the stirring plate; the pusher plate is slidably connected to the threaded rod and the limiting rod; the magnetic ring one and the magnetic ring two attract each other; the pusher plate is provided with a limiting member for restricting the sliding of the pusher plate; and the discharge pipe is provided with a blocking member for sealing the discharge pipe.

[0010] The present invention is further configured such that: the limiting member includes a positioning rod fixedly connected to the upper side of the pusher plate and a stop block rotatably connected to the positioning rod, and the support rod is provided with a through hole for the stop block to pass through.

[0011] The present invention is further configured such that: the sealing component includes a positioning plate fixedly connected to the discharge pipe, a sliding column slidably connected to the positioning plate, and a sealing block slidably connected to the discharge pipe; the sealing block is fixedly connected to the sliding column, and a spring is sleeved on the sliding column between the sealing block and the positioning plate.

[0012] The present invention is further configured such that a platform scale is fixedly connected to the base.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] A feeding device for preparing polyurethane resin, such as Figures 1-5 As shown, the device includes a base 1 and a feeding bucket 2 fixedly connected to the base 1. The feeding bucket 2 has an inlet pipe 3 and a outlet pipe 4. A support rod 5 is fixedly connected to the feeding bucket 2. A motor 6 is fixedly connected to the support rod 5. A threaded rod 7 is fixedly connected to the output shaft of the motor 6. The threaded rod 7 is rotatably connected to the feeding bucket 2. The threaded rod 7 is equipped with a stirring component for stirring raw materials. The feeding bucket 2 is equipped with a discharge component for controlling the discharge. The stirring component includes a stirring disc 8 threadedly connected to the threaded rod 7 and a limiting rod 9 slidably connected to the stirring disc 8. The stirring disc 8 has several through slots 10. The two ends of the limiting rod 9 are fixedly connected to the support rod 5 and the bottom side of the feeding bucket 2, respectively.

[0022] like Figures 1-5As shown, when using the loading device, the raw material can first be loaded into the discharge bucket 2 through the feed pipe 3, and then the motor 6 is started. The motor 6 will drive the threaded rod 7 to rotate. At this time, the mixing plate 8 is restricted by the limit rod 9 and cannot rotate. The mixing plate 8 will slide on the limit rod 9. When the mixing plate 8 slides, the mixing plate 8 will gradually approach the raw material and then contact the raw material. Then, part of the raw material will pass through the inner wall of the discharge bucket 2 and the outer wall of the mixing plate 8 and move to the upper side of the mixing plate 8. Another part of the raw material will pass through the through groove 10 to the upper side of the mixing plate 8. When the mixing plate 8 contacts the inner bottom side of the discharge bucket 2, the motor 6 will drive the threaded rod 7 to reverse. At this time, the mixing plate 8 will move upward, and the raw material on the mixing plate 8 will be lifted. Then, due to its own gravity, it will pass through the through groove 10 again and contact and merge with the raw material in the discharge bucket 2. By repeating this process, the raw material in the discharge bucket 2 can be stirred. It can also be used in conjunction with the discharge component to reduce raw material waste.

[0023] like Figures 1-5 As shown, the discharge assembly includes a pusher plate 11 slidably connected inside the discharge tank 2, several blocking rods 12 fixedly connected to the bottom side of the pusher plate 11, a magnetic ring 13 fixedly connected to the pusher plate 11, and a magnetic ring 14 fixedly connected to the mixing plate 8. The outer wall of the pusher plate 11 is in contact with the inner wall of the discharge tank 2. The pusher plate 11 is slidably connected to the threaded rod 7 and the limiting rod 9. The magnetic ring 13 and the magnetic ring 14 attract each other. The pusher plate 11 is provided with a limiting element to restrict the sliding of the pusher plate 11. The discharge pipe 4 is provided with a sealing element to block the discharge pipe 4. The limiting element includes... The upper side of the pusher plate 11 is fixedly connected to the positioning rod 15 and the positioning rod 15 is rotatably connected to the stop block 16. The support rod 5 is provided with a through hole 17 for the stop block 16 to pass through. The sealing component includes a positioning plate 18 fixedly connected to the discharge pipe 4, a sliding column 19 slidably connected to the positioning plate 18, and a sealing block 20 slidably connected to the discharge pipe 4. The sealing block 20 is fixedly connected to the sliding column 19. A spring 21 is sleeved on the sliding column 19 between the sealing block 20 and the positioning plate 18. When the sealing block 20 is no longer in contact with the discharge pipe 4, the spring 21 is in a compressed state.

[0024] like Figures 1-5As shown, when discharge is required, the placement bucket is first placed on the base 1, and then the motor 6 is turned on to drive the mixing plate 8 to move upward. When the mixing plate 8 moves upward, it will contact the pusher plate 11. At this time, the material between the mixing plate 8 and the pusher plate 11 will be squeezed out, and the material in the through groove 10 will be squeezed out by the blocking rod 12. When the bottom side of the blocking rod 12 is at the same horizontal line as the bottom side of the mixing plate 8, the magnetic ring 13 and the magnetic ring 14 will attract each other, so that the mixing plate 8 can drive the pusher plate 11 to move together. Then, the stop block 16 is rotated so that the stop block 16 can pass through the through hole 17. Then the motor 6 is started to drive the mixing plate 8 to move downward. At this time, the pusher plate 11 will also be driven downward by the mixing plate 8. When the mixing plate 8 and the pusher plate 11 move downward, the material will move downward. When the 11 comes into contact with the raw material, it will push the raw material, and then the raw material will push the sealing block 20, so that the sealing block 20 no longer contacts the discharge pipe 4. At this time, the raw material will flow out from the discharge pipe 4. When the motor 6 stops, the raw material will no longer push the sealing block 20. At this time, the spring 21 will reset and drive the sealing block 20 to reset and stop the discharge. If it is necessary to remove all the raw material in the discharge bucket 2, the motor 6 can be turned on to drive the mixing plate 8 and the push plate 11 to contact the bottom side of the discharge bucket 2. Then, the raw material adhering to the mixing plate 8, the push plate 11 and the blocking rod 12 will be squeezed out from the discharge pipe 4 when it contacts the bottom side of the discharge bucket 2, thereby avoiding a large amount of raw material remaining on the mixing components and reducing raw material waste.

[0025] like Figures 1-3 As shown, a platform scale 22 is fixedly connected to the base 1, which can be used to measure the weight of the polyurethane resin taken out each time, so as to avoid over-taking.

[0026] Working principle: When using the loading device, the raw material can be loaded into the discharge bucket 2 through the feed pipe 3 first, and then the motor 6 is started. The motor 6 will drive the threaded rod 7 to rotate. At this time, the mixing plate 8 is restricted by the limit rod 9 and cannot rotate. The mixing plate 8 will slide on the limit rod 9. When the mixing plate 8 slides, it will gradually approach the raw material and then contact it. Then, part of the raw material will pass through the inner wall of the discharge bucket 2 and the outer wall of the mixing plate 8 and move to the upper side of the mixing plate 8. Another part of the raw material will pass through the through groove 10 to the upper side of the mixing plate 8. When the mixing plate 8 contacts the inner bottom side of the discharge bucket 2, the motor 6 will drive the threaded rod 7 to reverse. At this time, the mixing plate 8 will move upward, and the raw material on the mixing plate 8 will be lifted. Then, due to its own gravity, it will pass through the through groove 10 again and contact and merge with the raw material in the discharge bucket 2. By repeating this process, the raw material in the discharge bucket 2 can be stirred.

[0027] When discharge is required, first place the polyurethane resin container on the platform scale 22, then turn on the motor 6 to drive the mixing plate 8 to move upward. When the mixing plate 8 moves upward, it will contact the pusher plate 11. At this time, the material between the mixing plate 8 and the pusher plate 11 will be squeezed out, and the material in the through groove 10 will be squeezed out by the blocking rod 12. When the bottom side of the blocking rod 12 is at the same horizontal line as the bottom side of the mixing plate 8, the magnetic ring 13 and the magnetic ring 14 will attract each other, so that the mixing plate 8 can drive the pusher plate 11 to move together. Then rotate the stop block 16 so that the stop block 16 can pass through the through hole 17, and then start the motor. Motor 6 drives the mixing plate 8 to move downwards. At this time, the pusher plate 11 will also be driven downwards by the mixing plate 8. When the mixing plate 8 and the pusher plate 11 come into contact with the raw material, they will push the raw material. Then the raw material will push the sealing block 20, so that the sealing block 20 no longer comes into contact with the discharge pipe 4. At this time, the raw material will flow out from the discharge pipe 4. When the platform scale 22 shows that the weight has reached the picking value, the motor 6 can be turned off. At this time, the pusher plate 11 and the mixing plate 8 will no longer push the raw material, and the raw material will no longer push the sealing block 20. At this time, the spring 21 will reset and drive the sealing block 20 to reset and stop the discharge.
