Description

Technical Field

[0001] The utility model belongs to the field of raw material stirring devices, in particular to a polyurethane AB material stirring device. Background Art

[0002] Bubble foam products are a kind of material with dense pores, low density, light weight, and functions of cushioning protection, heat insulation, sound insulation, shockproof, etc. Polyurethane foam (PU foam) is one of the bubble cotton. The pre-production step of polyurethane foam requires that the AB material be stirred evenly by a high-speed stirring device to become PU material.

[0003] Before stirring, the existing AB material stirring device directly feeds the materials into the stirring barrel through the A material feeding device and the B material feeding device. Although the outlets of the feeding devices are equipped with quantitative discharge valves, theoretically the materials can be fed according to the preset values. However, sometimes the accuracy of the quantitative discharge valves or the weighing devices are deviated, resulting in feeding deviations. However, since the materials are mixed together (AB materials are in a gelatinous state), it is impossible to add or subtract specific materials later, and the mixed materials can only be discarded, which is quite wasteful. Utility Model Content

[0004] Therefore, the technical problem to be solved by the utility model is to overcome the current problem that polyurethane AB materials are directly fed into the mixing barrel of the stirring device before stirring. Once the feeding amount is inaccurate, since they have already been mixed together, it is impossible to add or subtract a specific material, resulting in waste of the previous mixed material.

[0005] In order to solve the above technical problems, the utility model provides a polyurethane AB material stirring device, including a stirring barrel, a stirring structure, a separated material storage container and a weighing device, wherein the weighing device is arranged at the outer bottom of the stirring barrel, and the sensing end of the weighing device bears the weight of the stirring barrel, the separated material storage container is arranged inside the stirring barrel, and the separated material storage container is provided with at least two separated spaces, different materials can enter different separated spaces respectively, and the materials in the separated material storage containers enter the stirring barrel after coming out, and the signal output end of the weighing device can be connected to the signal input end of the discharge valve of the A material feeding equipment and the signal input end of the discharge valve of the B material feeding equipment, and a first liquid level sensor and a second liquid level sensor are respectively provided above the two separated spaces.

[0006] Preferably, the partitioned material storage container comprises a barrel body, a partition plate and a bottom cover, wherein the bottom cover is arranged at the bottom of the barrel body, and the partition plate is arranged in the barrel body to divide the barrel body into at least two partitioned spaces.

[0007] Preferably, a supporting grid frame is provided in the middle of the mixing barrel, the bottom cover is hinged to the bottom of the barrel body, and the separated material storage container can be raised and lowered in the mixing barrel, so that the bottom cover can be opened or closed.

[0008] Preferably, it also includes a screw rod, a ball nut and a lifting motor, the two ends of the outer side of the barrel body are respectively slidably connected to the inner wall of the mixing barrel, the ball nut is fixed to the center of the barrel body, and the ball nut is sleeved on the outside of the screw rod, the stirring structure includes a stirring shaft and a stirring motor, the stirring motor is arranged in the space at the bottom of the mixing barrel, the output shaft of the stirring motor passes through the bottom plate of the mixing barrel, the output shaft of the stirring motor is concentrically fixed with the stirring shaft, the screw rod is rotatably connected to the center of the support grid frame and the top of the stirring shaft at two places, the lifting motor is fixed to the top of the mixing barrel, and the lifting motor drives the screw rod to rotate.

[0009] Preferably, it further comprises a plurality of supporting feet, the weighing device is a weighing sensor, the supporting feet are fixed under the mixing barrel, and a weighing device is arranged between each supporting foot and the mixing barrel.

[0010] The technical solution of the utility model has the following beneficial effects:

[0011] The utility model is provided with a separated material storage container. When feeding the AB materials, it is preferred to temporarily feed them into the separated material storage container, and the materials are stored separately. During the feeding process, the A material and the B material are weighed separately. When the feeding amount of the A material and the B material is not accurate, they can be added or subtracted to correct them respectively, so as to achieve a more accurate feeding amount. This avoids the phenomenon that after the conventional polyurethane stirring device mixes and feeds, it is found that the feeding amount is not accurate, and it cannot be corrected, and can only be directly discarded, resulting in waste.

[0012] In addition to arranging a weighing device to weigh and measure the feeding amount, the utility model also has a first liquid level sensor and a second liquid level sensor, which can measure the volume of material A and material B in the separated storage container, further ensuring that the feeding amount of material A and material B meets the preset value and ensures product quality.

[0019] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0020] The utility model provides a polyurethane AB material stirring device, comprising a stirring barrel 1, a stirring structure 2, a partitioned material storage container 3 and a weighing device 4, wherein the weighing device 4 is arranged at the outer bottom of the stirring barrel 1, and the sensing end of the weighing device 4 bears the weight of the stirring barrel 1, the partitioned material storage container 3 is arranged inside the stirring barrel 1, the partitioned material storage container 3 is provided with at least two partition spaces 41, different materials can enter different partition spaces 41 respectively, and the materials in the partitioned material storage container 3 enter the stirring barrel 1 after coming out, the signal output end of the weighing device 4 can be connected with the signal input end of the discharge valve of the A material feeding device and the signal input end of the discharge valve of the B material feeding device, and a first liquid level sensor 5 and a second liquid level sensor 6 are respectively provided above the two partition spaces 41.

[0021] The basic working principle of the utility model is as follows: the A material feeding device and the B material feeding device feed the two separated spaces 41 of the separated storage container 3 in turn. If the A material feeding device feeds first, during this process, the weighing device 4 weighs the A material of the separated storage container 3, and when the preset weight is reached, the discharge valve of the A material feeding device is closed; then the B material feeding device feeds, during this process, the weighing device 4 weighs the A+B materials of the separated storage container 3, and when the total weight reaches the preset value, the discharge valve of the B material feeding device is closed. Then after a period of time, when the liquid levels of the A material and the B material are flat, the first liquid level sensor 5 and the second liquid level sensor 6 begin to measure the liquid levels of the two separated spaces 41. When the feeding amount of the A material and the B material exceeds the error tolerance, the first liquid level sensor 5 and the second liquid level sensor 6 will alarm to remind the workers, and the workers will manually add or reduce the material. When the feeding amount meets the standard, the first liquid level sensor 5 and the second liquid level sensor 6 will stop alarming. At this point, the feeding is completed. Then the materials in the separated material storage container 3 will enter the mixing barrel 1, and the mixing structure 2 will mix the materials.

[0022] In the above process, material A and material B are fed into different spaces in the feeding process. The weighing device 4 is used to weigh the feeding, and the subsequent liquid level measurement and the double measurement of weight and volume make the feeding amount more accurate. In addition, by feeding into different spaces separately, the feeding amount can be adjusted in time after the liquid level measurement to ensure that there will be no mistakes, avoiding waste caused by measuring errors after mixing, and tracing back which specific discharge device (discharge valve) has an error, so that errors can be corrected in time to avoid subsequent feeding errors.

[0023] The separated material storage container 3 includes a barrel body 31, a partition plate 32 and a bottom cover 33. The bottom cover 33 is arranged at the bottom of the barrel body 31, and the partition plate 32 is arranged inside the barrel body 31, so as to divide the barrel body 31 into at least two separated spaces 41. The barrel body 31 and the bottom cover 33 can allow two materials to be temporarily separated and stored in the separated material storage container 3, which is convenient for weighing, measuring volume, and adding or subtracting materials.

[0024] A support grid frame 7 is provided in the middle of the mixing barrel 1, and a bottom cover 33 is hinged at the bottom of the barrel body 31. The separated material storage container 3 can be raised and lowered in the mixing barrel 1, so that the bottom cover 33 can be opened or closed. When the separated material storage container 3 rises, the bottom cover 33 automatically opens, and the material leaks out from the bottom of the barrel body 31 and enters the mixing barrel 1. When the mixing barrel 1 descends, the bottom cover 33 contacts the support grid frame 7, and the bottom cover 33 is closed.

[0025] The utility model also includes a screw 8, a ball nut 9 and a lifting motor 10. The two ends of the outer side of the barrel body 31 are respectively slidably connected to the inner wall of the mixing barrel 1. The ball nut 9 is fixed at the center of the barrel body 31. The ball nut 9 is sleeved on the outside of the screw 8. The stirring structure 2 includes a stirring shaft 21 and a stirring motor 22. The stirring motor 22 is arranged in the space at the bottom of the mixing barrel 1. The output shaft of the stirring motor 22 passes through the bottom plate of the mixing barrel 1. The output shaft of the stirring motor 22 is fixed concentrically with the stirring shaft 21. The screw 8 is rotatably connected at two places to the center of the support grid frame 7 and the top of the stirring shaft 21. The lifting motor 10 is fixed at the top of the mixing barrel 1. The lifting motor 10 drives the screw 8 to rotate. The lifting motor 10 can rotate the screw 8, thereby driving the ball nut 9 to slide on the screw 8, and finally driving the separation storage container 3 to rise and fall. The stirring motor 22 rotates the stirring shaft 21, thereby stirring the material in the mixing barrel 1. Since the screw rod 8 and the stirring shaft 21 are rotatably connected, the two can rotate independently without affecting each other, that is, the lifting and lowering of the separation storage container 3 and the stirring of the stirring shaft 21 do not interfere with each other.

[0026] The utility model also includes a plurality of supporting feet 11, and a weighing device 4 is a weighing sensor. The supporting feet 11 are fixed under the mixing barrel 1, and a weighing device 4 is arranged between each supporting foot 11 and the mixing barrel 1. The weighing device 4 is set as a weighing sensor and is arranged between the supporting feet 11 and the mixing barrel 1, which not only reduces the weight of the equipment, but also makes the weighing device 4 integrated with the entire equipment, which is convenient for equipment transportation.

[0027] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
