[0001] The utility model relates to the technical field of stirring equipment, and particularly relates to a stirring device. Background Art

[0002] With the progress of technology, various chemical materials emerge in an endless stream. And different chemical materials can produce new-performance chemical materials under different ratios. This process usually requires the use of stirring equipment to stir and mix various chemical raw materials. For example, a horizontal chemical raw material mixer disclosed in the patent publication number CN219663407U. This mixer is provided with a horizontal stirring barrel and stirring blades are arranged in the horizontal stirring barrel. The horizontal design enables the raw materials to be fully driven by the stirring blades, causing the raw materials to turn up and down in the stirring barrel, thereby making the raw materials mix more evenly.

[0003] However, after the above-mentioned mixer completes the stirring of various chemical raw materials, it discharges materials through the discharge port on one side of the barrel body. Due to the horizontal design of the stirring barrel, the discharging force at the discharging end is poor, resulting in some materials adhering to the barrel wall and the stirring blades and being difficult to discharge, making the discharging effect of the device poor. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the above technical deficiencies, and propose a stirring device to solve the technical problem of poor discharging effect in the prior art.

[0005] To achieve the above technical purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides a stirring device, which includes a tank body, a screw, a scraper, a stirring frame and a motor. The screw is coaxially arranged in the tank body. The scraper is coaxially arranged in the tank body and is in one-way meshing with the screw. The stirring frame is sleeved outside the screw, and the end side of the stirring frame away from the scraper is in one-way rotational connection with the screw. The other end side of the stirring frame penetrates through the scraper. The motor is installed on one side of the tank body and is used to drive the screw to rotate clockwise or counterclockwise.

[0007] In some embodiments, the tank body is horizontally arranged.

[0008] In some embodiments, the outer edge of the scraper abuts against the inner wall of the tank body. A screw sleeve is provided at the place where the scraper is adapted to the screw.

[0009] In some embodiments, an unslotted area is provided outside the end side of the screw close to the scraper, and the screw sleeve can be disengaged from the screw and is adapted to the unslotted area of the screw.

[0010] In some embodiments, a pressure relief hole is provided at the center of the end side of the tank body close to the scraper, and the output shaft of the motor is fixedly connected to the end of the screw rod close to the pressure relief hole.

[0011] In some embodiments, the stirring frames are symmetrically arranged on both sides of the screw rod, and the outer edge of the stirring frame is in contact with the inner wall of the tank body. The through part of the stirring frame is slidably connected to the scraper.

[0012] In some embodiments, a connecting plate is fixedly arranged at the end side of the stirring frame far from the scraper. The connecting plate is sleeved outside the screw rod, and a one-way bearing is arranged between the connecting plate and the screw rod.

Detailed implementation manners

[0022] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0023] In order to solve the technical problem of poor discharging effect, the present utility model provides a stirring device, which can achieve a better discharging effect.

[0024] It should be noted that the stirring device described in the present utility model is used for but not limited to chemical raw material stirring, etc. For the convenience of description, in the present utility model, only a stirring device applied to a chemical stirring device is taken as an example for description, and the principle of a stirring device applied to other types of devices is substantially the same as that applied to a chemical stirring device, which will not be elaborated here one by one.

[0025] Please refer to Figures 1-4 , wherein, Figure 1 is a structural schematic diagram of a stirring device in an embodiment of the present utility model. A stirring device includes a tank body 100, a screw 200, a scraper 300, a stirring frame 400 and a motor 500. The screw 200 is coaxially arranged inside the tank body 100. The scraper 300 is coaxially arranged inside the tank body 100 and is in one-way meshing with the screw 200. The stirring frame 400 is sleeved outside the screw 200, and one end side of the stirring frame 400 away from the scraper 300 is in one-way rotational connection with the screw 200. The other end side of the stirring frame 400 penetrates through the scraper 300. The motor 500 is installed on one side of the tank body 100 and is used to drive the screw 200 to rotate clockwise or counterclockwise;

[0026] Among them, the tank body 100 is horizontally arranged;

[0027] In this embodiment, the motor 500 is started. The motor 500 rotates counterclockwise to drive the screw 200 to rotate. The screw 200 drives the stirring frame 400 to rotate counterclockwise, so as to stir the material. Since the scraper 300 is unidirectionally engaged with the screw 200, at this time, the scraper 300 will not translate outside the screw 200. After the stirring frame 400 finishes stirring, the motor 500 rotates clockwise. At this time, the scraper 300 can be threadedly engaged with the screw 200. At the same time, the stirring frame 400 stops rotating and creates a certain resistance to prevent the scraper 300 from rotating by itself. In this way, the scraper 300 can move in the tank body 100 along the axis of the screw 200, so as to extrude the material to one side of the tank body 100 and discharge it, and at the same time scrape off the material adhered to the stirring frame 400. The device can stir the material by rotating counterclockwise and can scrape and discharge the material by rotating clockwise, avoiding the situation of material adhesion and waste, and ensuring the discharging effect.

[0028] In one embodiment, please refer to Figure 2 - Figure 3 , the outer edge of the scraper 300 is in contact with the inner wall of the tank body 100. A screw sleeve 310 is provided at the place where the scraper 300 is adapted to the screw 200. The screw sleeve 310 is threadedly sleeved on the outside of the screw 200. The screw sleeve 310 is unidirectionally engaged with the screw 200. An unslotted area is provided on the outer side of the end of the screw 200 close to the scraper 300. The screw sleeve 310 can be disengaged from the screw 200 and is adapted to the unslotted area of the screw 200;

[0029] In this embodiment, when the motor 500 drives the screw 200 to rotate counterclockwise, the screw sleeve 310 in the middle of the scraper 300 cannot be engaged with the screw 200. At this time, the scraper 300 is in the unslotted area of the screw 200. However, the stirring frame 400 rotates with the screw 200. Since one end of the stirring frame 400 penetrates through the scraper 300, the stirring frame 400 drives the scraper 300 to rotate together, and the scraper 300 is located in place and does not produce horizontal movement;

[0030] In one embodiment, please refer to Figure 1 And Figure 2 , a pressure relief hole 110 is opened at the center of the end side of the tank body 100 close to the scraper 300. The output shaft of the motor 500 is fixedly connected to the end of the screw 200 close to the pressure relief hole 110;

[0031] In this embodiment, the pressure relief hole 110 can make the scraper 300 move more stably in the tank body 100, avoiding the influence of uneven air pressure in the tank body 100 on the operation effect of the scraper 300.

[0032] In one embodiment, please refer to Figure 1 And Figure 2, the stirring frame 400 is symmetrically arranged on both sides of the screw rod 200, and the outer edge of the stirring frame 400 is in contact with the inner wall of the tank body 100. The stirring frame 400 is slidably connected to the through part of the scraping plate 300. A connecting plate 410 is fixedly arranged at the end side of the stirring frame 400 far away from the scraping plate 300. The connecting plate 410 is sleeved outside the screw rod 200. A same one-way bearing 420 is arranged between the connecting plate 410 and the screw rod 200. The one-way bearing 420 is used to make the screw rod 200 drive the stirring frame 400 to rotate unidirectionally. Two installation grooves 411 are symmetrically formed on the side of the connecting plate 410 close to the tank body 100. A clamping block 412 is slidably arranged in each of the two installation grooves 411. A spring 413 is fixedly connected to the end side of the clamping block 412 located in the installation groove 411. The other end of the spring 413 is fixedly connected to the inner wall of the installation groove 411. A plurality of clamping grooves 120 are annularly arranged on the inner wall of the end side of the tank body 100 close to the connecting plate 410. The clamping grooves 120 are adapted to the clamping blocks 412;

[0033] In this embodiment, when the motor 500 rotates clockwise, the threads of the screw rod 200 and the thread of the screw sleeve 310 are correspondingly engaged. At the same time, the connection end side of the screw rod 200 and the connecting plate 410 on the stirring frame 400 is connected through a one-way bearing 420. The one-way bearing 420 can transmit the power of the counterclockwise rotation of the screw rod 200 and does not transmit the power of the clockwise rotation. In this way, when the screw rod 200 rotates clockwise, the stirring frame 400 does not rotate following the screw rod 200;

[0034] Furthermore, a clamping block 412 and a clamping groove 120 are respectively arranged between the connecting plate 410 and the end side of the tank body 100 close to it. The spring 413 in the installation groove 411 on the connecting plate 410 can make the clamping block 412 embed into the clamping groove 120. At the same time, the embedding end of the clamping block 412 is hemispherical. When the screw rod 200 rotates counterclockwise, the one-way bearing 420 does not transmit power, and the clamping block 412 further clamps the stirring frame 400 on the connecting plate 410. In this way, the stirring frame 400 has a greater resistance to stop rotating;

[0035] Even further, when the stirring frame 400 stops rotating, the scraping plate 300 can be limited, so that the scraping plate 300 moves more stably outside the screw rod 200 for operation.

[0036] In one of the embodiments, please refer to Figure 1 , a feed inlet 130 and a discharge outlet 140 are respectively arranged at the top and one side of the tank body 100. A support 150 is arranged at the bottom of the tank body 100. A shock-absorbing foot 160 is arranged at the bottom of the support 150.

[0037] For a better understanding of the present invention, the following is combined with Figures 1 to 4The technical solution of the present utility model will be described in detail: Start the motor 500. The motor 500 rotates counterclockwise and drives the screw rod 200 to rotate. When the motor 500 drives the screw rod 200 to rotate counterclockwise, the middle screw sleeve 310 of the scraper 300 cannot mesh with the screw rod 200. At this time, the scraper 300 is in the non-grooved area of the screw rod 200. However, the stirring frame 400 rotates with the screw rod 200. Since one end of the stirring frame 400 penetrates through the scraper 300, the stirring frame 400 drives the scraper 300 to rotate together. And the scraper 300 is located in place and does not produce horizontal movement. After the stirring of the stirring frame 400 is completed, make the motor 500 rotate clockwise. When the motor 500 rotates clockwise, the thread of the screw rod 200 corresponds to and meshes with the thread of the screw sleeve 310. At the same time, the connection end side of the screw rod 200 and the connecting plate 410 on the stirring frame 400 is connected through a one-way bearing 420. This one-way bearing 420 can transmit the power of the counterclockwise rotation of the screw rod 200 and does not transmit the power of the clockwise rotation. In this way, when the screw rod 200 rotates clockwise, the stirring frame 400 does not rotate with the screw rod 200;

[0038] Further, a clamping block 412 and a clamping groove 120 are respectively provided between the connecting plate 410 and the side close to the tank body 100. The spring 413 in the mounting groove 411 on the connecting plate 410 can make the clamping block 412 embed into the clamping groove 120. At the same time, the embedding end of the clamping block 412 is hemispherical. When the screw rod 200 rotates counterclockwise, the one-way bearing 420 does not transmit power, and the clamping block 412 further clamps the stirring frame 400 on the connecting plate 410. In this way, the stirring frame 400 has a large resistance to stop rotating;

[0039] Even further, when the stirring frame 400 stops rotating, the scraper 300 can be limited, so that the scraper 300 moves more stably outside the screw rod 200 for operation, so as to squeeze the material to one side of the tank body 100 and discharge it. At the same time, the material adhered to the stirring frame 400 is scraped off together. The device can stir the material by rotating counterclockwise and can scrape and discharge the material by rotating clockwise, avoiding the situation of material adhesion and waste, and ensuring the discharging effect.

[0040] The above specific implementation manners of the present utility model do not constitute a limitation on the protection scope of the present utility model. Any other corresponding changes and deformations made according to the technical concept of the present utility model should be included in the protection scope of the claims of the present utility model.
