Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic mixing technology, specifically a TPU plastic addition and mixing device. Background Technology
[0002] The mixing device can fully mix TPU plastic with other additives (such as pigments, plasticizers, flame retardants, etc.) or raw materials to ensure that each component is evenly distributed in the plastic, thereby improving the performance and stability of plastic products.
[0003] Currently, in existing technologies, stirring devices typically use a motor output shaft to drive a rotating shaft to stir TPU plastic and other additives. However, when TPU plastic contains a small amount of moisture, the intermolecular forces change, making the plastic particles more viscous and prone to sticking together during stirring. This adhesion not only reduces the mixing effect of TPU plastic and other additives but also results in uneven color and properties in the mixed material. Therefore, a TPU plastic addition stirring device is proposed. Utility Model Content
[0004] The main objective of this invention is to provide a TPU plastic addition and stirring device that can solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention proposes a TPU plastic addition and mixing device, comprising a mixing tank, a cover plate fixedly connected to the upper side of the mixing tank, a discharge port on the outer wall of the mixing tank, a feeding port at the bottom of the mixing tank, a U-shaped frame fixedly connected to the upper side of the cover plate, and a mixing mechanism disposed within the mixing tank, the mixing mechanism comprising:
[0006] A rotating shaft, the bottom of which is rotatably connected to the inner wall of the mixing tank, the top of which passes through the cover plate and is rotatably connected to the cover plate, and spiral blades are fixedly connected to the outer wall of the rotating shaft;
[0007] A sealed vent is rotatably connected to a rotating shaft. A motor is fixedly connected to the outer wall of the U-shaped frame. A synchronous pulley is fixedly connected to the bottom of the output shaft of the motor. A synchronous pulley is fixedly connected to the outer wall of the rotating shaft. The synchronous pulley is connected to the synchronous pulley through a synchronous belt drive.
[0008] A sleeve rod is fixedly connected to the outer wall of the rotating shaft. A T-rod is sleeved on the sleeve rod, and the T-rod is elastically connected to the inner wall of the sleeve rod by a return spring.
[0009] The agitator is fixedly connected to the end of the T-rod away from the sleeve rod. It rotates through the output shaft of the motor. Under the transmission action of the synchronous belt, the rotating shaft can drive the spiral blades to rotate, thereby driving the sleeve rod, the T-rod and the agitator to rotate, so as to fully mix the TPU plastic with other additives.
[0010] Preferably, a vertical rod is fixedly connected to the outer wall of the T-bar, and a rotating wheel is rotatably connected to the top of the vertical rod.
[0011] Preferably, the cover plate has a groove on its lower side, and the rotating wheel can move in the groove.
[0012] Preferably, the T-rod has a through groove, the inner wall of the sleeve is connected to the inner wall of the rotating shaft, and the T-rod is connected to the inner wall of the stirring rod.
[0013] Preferably, the outer wall of the stirring rod has a first opening, the inner wall of the stirring rod is fixedly connected to a first limiting ring, the inner wall of the stirring rod is slidably connected to an inner rod, and the outer wall of the inner rod has a second opening. By introducing dry gas into the sealed vent, the dry gas enters the stirring rod through the T-rod, and then the inner rod is squeezed down, so that the first opening and the second opening are connected, thereby causing the gas to be ejected. This improves the mixing effect of TPU plastic with other additives and also removes the small amount of moisture contained in the TPU plastic.
[0014] Preferably, the inner rod and the inner wall of the stirring rod are elastically connected by a connecting spring, and a limit ring is fixedly connected to the inner wall of the stirring rod.
[0015] This invention provides a TPU plastic addition and stirring device. It has the following beneficial effects:
[0016] (1) The TPU plastic addition and stirring device uses a stirring mechanism to introduce dry gas into a sealed vent. The dry gas then enters the stirring rod through the T rod, squeezing the inner rod down and connecting the first and second vents, causing the gas to be ejected. As the rotating shaft drives the spiral blades to rotate, it drives the sleeve rod, T rod and stirring rod to rotate, improving the mixing effect of TPU plastic with other additives. At the same time, it can also remove the small amount of moisture contained in the TPU plastic, improving the use effect of the device.
[0017] (2) The TPU plastic additive mixing device uses a stirring mechanism to make the rotating shaft drive the T rod and the stirring rod to rotate. During this process, the rotating wheel moves in the groove, causing the T rod to extend and retract in the sleeve rod, which drives the stirring rod to move and changes the position of the stirring rod, thereby further improving the mixing effect of TPU plastic and other additives.

[0028] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0029] 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.
[0030] Please see Figures 1-7 This utility model proposes a TPU plastic addition and stirring device, including a stirring box 1, a cover plate 2 fixedly connected to the upper side of the stirring box 1, a discharge port 101 opened on the outer wall of the stirring box 1, a feeding port 3 provided at the bottom of the stirring box 1, a U-shaped frame 4 fixedly connected to the upper side of the cover plate 2, and a stirring mechanism 5 provided in the stirring box 1.
[0031] In this embodiment of the invention, in order to add TPU plastic and additives for stirring, the stirring mechanism 5 specifically includes a rotating shaft 51, a sealed vent 53, a sleeve rod 55, and a stirring rod 59. The bottom of the rotating shaft 51 is rotatably connected to the inner wall of the mixing tank 1, and the top of the rotating shaft 51 passes through the cover plate 2 and is rotatably connected to the cover plate 2. A spiral blade 52 is fixedly connected to the outer wall of the rotating shaft 51. The sealed vent 53 is rotatably connected to the rotating shaft 51. A motor 54 is fixedly connected to the outer wall of the U-shaped frame 4. A synchronous pulley 1 is fixedly connected to the bottom of the output shaft of the motor 54, and a synchronous pulley 2 is fixedly connected to the outer wall of the rotating shaft 51. The synchronous pulley 1 and the synchronous pulley 2... The sleeve 55 is fixedly connected to the outer wall of the rotating shaft 51 via a synchronous belt drive. The sleeve 55 is fitted with a T-rod 56, and the T-rod 56 is elastically connected to the inner wall of the sleeve 55 by a return spring. The stirring rod 59 is fixedly connected to the end of the T-rod 56 away from the sleeve 55. TPU plastic and additives are added through the feeding port 3. During the rotation of the output shaft of the motor 54, the rotating shaft 51 can drive the spiral blade 52 to rotate under the transmission action of the synchronous belt, which transports the TPU plastic and additives into the mixing tank 1. At the same time, it drives the rotation of the sleeve 55, the T-rod 56 and the stirring rod 59 to fully mix the TPU plastic and other additives.
[0032] Furthermore, to improve the mixing effect of TPU plastic with other additives, specifically, a through groove 561 is provided in the T-rod 56, the inner wall of the sleeve 55 is connected to the inner wall of the rotating shaft 51, the T-rod 56 is connected to the inner wall of the stirring rod 59, a through opening 591 is provided on the outer wall of the stirring rod 59, a limit ring 592 is fixedly connected to the inner wall of the stirring rod 59, an inner rod 593 is slidably connected to the inner wall of the stirring rod 59, a through opening 594 is provided on the outer wall of the inner rod 593, and the inner rod 593 and the inner wall of the stirring rod 59 are elastically connected by a connecting spring. Next, a limiting ring 595 is fixedly connected to the inner wall of the stirring rod 59. Dry air is introduced into the sealed vent 53, which can be done by a blower. The dry air passes through the rotating shaft 51 to the sleeve rod 55 and the T rod 56, and then enters the stirring rod 59, squeezing the inner rod 593 down to the limiting ring 595, so that the first vent 591 and the second vent 594 are connected, thereby causing the gas to be ejected. This improves the mixing effect of TPU plastic with other additives and also removes the small amount of moisture contained in the TPU plastic, thus improving the use effect of the device.
[0033] Furthermore, in order to further improve the mixing effect of TPU plastic with other additives, specifically, a vertical rod 57 is fixedly connected to the outer wall of the T rod 56, and a rotating wheel 58 is rotatably connected to the top of the vertical rod 57. A groove 21 is opened on the lower side of the cover plate 2, and the rotating wheel 58 can move in the groove 21. During the rotation of the T rod 56 and the stirring rod 59 driven by the rotating shaft 51, the rotating wheel 58 moves in the groove 21, causing the T rod 56 to extend and retract in the sleeve rod 55, driving the stirring rod 59 to move, causing the position of the stirring rod 59 to change, thereby further improving the mixing effect of TPU plastic with other additives.
[0034] In addition, when no more gas is added to the sealed vent 53, the inner rod 593 is driven to abut against the limiting ring 592 under the reset action of the connecting spring, thereby causing the first vent 591 and the second vent 594 to be misaligned, preventing impurities from entering the stirring rod 59.
[0035] It should be noted that the above electrical components are all existing technology products. They are selected, installed and debugged by those skilled in the art according to the needs of use to ensure that all electrical appliances can work normally. The components are all general standard parts or components known to those skilled in the art. Their structure and principle can be known by those skilled in the art through technical manuals or conventional experimental methods. The applicant does not impose any specific restrictions here.
[0036] In use, TPU plastic and additives are first added through the feeding port 3. Then, as the output shaft of the motor 54 rotates, the synchronous belt drives the rotating shaft 51 to rotate the spiral blades 52, conveying the TPU plastic and additives into the mixing tank 1. At the same time, the sleeve rod 55, T rod 56 and stirring rod 59 are rotated to fully mix the TPU plastic and other additives. Meanwhile, dry air is added to the sealed vent 53. This process can be carried out by a blower. The dry air passes through the rotating shaft 51 to the sleeve rod 55 and T rod 56, and then enters the stirring rod 59, squeezing the inner rod 593 down to the limit ring 595, connecting the first vent 591 and the second vent 594, thus causing the gas to be ejected. This not only assists in the mixing of TPU plastic and other additives, but also removes the small amount of moisture contained in the TPU plastic.
[0037] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
