[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Please refer to Figure 1-Figure 5The utility model provides a technical solution: a multifunctional electric stirrer, comprising a bottom plate 1 and a fixing frame 2, a connecting plate 3 is fixedly connected to the top outer surface of the fixing frame 2, a first positive and negative screw rod 4 is rotatably penetrated on the outer surface of the connecting plate 3, a second positive and negative screw rod 5 is fixedly connected to the bottom outer surface of the first positive and negative screw rod 4, a knob 23 is fixedly connected to the top outer surface of the first positive and negative screw rod 4, two threaded blocks 6 are threadedly connected to the outer surfaces of the first positive and negative screw rod 4 and the second positive and negative screw rod 5, and the outer surfaces of the left and right sides of the threaded block 6 are rotatably connected to the inclined stirring rod 7 The outer surfaces of the two inclined stirring rods 7 on the left and the two inclined stirring rods 7 on the right away from the threaded block 6 are rotatably connected to a rotating seat 8, and the outer surface of the rotating seat 8 is fixedly connected to a transverse stirring rod 9. In this embodiment, according to the diameter of the container, the knob 23 is rotated, and the knob 23 drives the first forward and reverse screw rod 4 and the second forward and reverse screw rod 5 to rotate, thereby driving the two threaded blocks 6 on the first forward and reverse screw rod 4 and the second forward and reverse screw rod 5 to move. When the two threaded blocks 6 move, the angle between the two inclined stirring rods 7 changes, thereby adjusting the position of the transverse stirring rod 9.
[0026] A placement groove is provided on the top outer surface of the bottom plate 1, and four symmetrically arranged support plates are fixedly connected to the top outer surface of the bottom plate 1, and the third positive and negative screw rods 10 are rotatably connected to the opposite outer surfaces of the two rear support plates, and a first motor 11 is fixedly installed on the right outer surface of the right side support plate close to the rear end, and the output end of the first motor 11 is fixedly connected to the outer surface of the third positive and negative screw rods 10, and the outer surface of the third positive and negative screw rods 10 is threadedly connected to two threaded plates 12, and the opposite outer surfaces of the two threaded plates 12 are fixedly connected to two first springs 13 and a pressure sensor 15, and the other ends of the two first springs 13 are fixedly connected to an arc clamping plate 14, and a controller is fixedly installed on the top outer surface of the bottom plate 1 (not shown in the figure). In this embodiment, when fixing the container, the container is placed in the placement groove, the first motor 11 is turned on, and the first A motor 11 drives the third forward and reverse screw rod 10 to rotate. The rotation of the third forward and reverse screw rod 10 drives the two threaded plates 12 to move towards each other. The movement of the two threaded plates 12 drives the two arc-shaped clamping plates 14 to move towards each other until the two arc-shaped clamping plates 14 collide with the outer wall of the container. The arc-shaped clamping plates 14 will drive the container to move toward the middle end and compress the first spring 13 until the arc-shaped clamping plates 14 contact with the pressure sensor 15. When the arc-shaped clamping plates 14 contact with the pressure sensor 15, when the pressure sensor 15 senses a certain value, it sends a signal to the controller. The controller receives the signal and stops the first motor 11, thereby completing the fixing of the container to avoid damage to the container due to excessive pressure and avoid instability of the container during stirring due to insufficient pressure.
[0027] An inverted L-shaped plate 20 is fixedly connected to the top outer surface of the bottom plate 1, and an electric push rod 21 is fixedly installed on the downward outer surface of the top of the inverted L-shaped plate 20, and the output end of the electric push rod 21 is fixedly connected to a mounting plate, and a second motor 22 is fixedly installed on the bottom outer surface of the mounting plate, and the output end of the second motor 22 is fixedly connected to the top outer surface of the fixed frame 2. In this embodiment, the electric push rod 21 is turned on, and the electric push rod 21 works so that the inclined stirring rod 7 and the horizontal stirring rod 9 are placed inside the container, and the second motor 22 works and drives the fixed frame 2, so that the first forward and reverse screw rod 4 and the second forward and reverse screw rod 5 rotate as a whole, so that the inclined stirring rod 7 and the horizontal stirring rod 9 stir the medium inside the container.
[0028] The outer surface of the horizontal stirring rod 9 is fixedly connected to a vertical plate 16, and a plurality of movable rods 17 are movably inserted into the outer surface of the vertical plate 16. The outer surfaces of the plurality of movable rods 17 are fixedly connected to scraper bars 19. In this embodiment, when the second motor 22 is driven, the scraper bars 19 are driven to scrape the residual medium on the inner wall of the container to improve the stirring effect.
[0029] The relative outer surfaces of the two front support plates are fixedly connected with a sliding rod, and the two threaded plates 12 are movably mounted on the outer surfaces of the sliding rod. In this embodiment, when the first motor 11 drives the third forward and reverse screw rod 10 to rotate, the threaded plate 12 slides on the outer surface of the sliding rod, so that the threaded plate 12 moves stably, avoiding the threaded plate 12 from rotating with the rotation of the third forward and reverse screw rod 10.
[0030] Two L-shaped rods arranged in a mirror image are fixedly connected to the bottom outer surface of the connecting plate 3, and two vertical plates 16 and two scraper strips 19 are respectively sleeved on the outer surfaces of the two L-shaped rods. In this embodiment, when the angle between the two inclined stirring rods 7 changes, the vertical plates 16 and the scraper strips 19 are driven to slide on the outer surfaces of the L-shaped rods, so that the vertical plates 16 and the scraper strips 19 perform linear motion in the lateral direction.
[0031] A plurality of second springs 18 are fixedly connected to the opposite outer surfaces of the two vertical plates 16, and the other ends of the plurality of second springs 18 are fixedly connected to the scraper strip 19. The plurality of second springs 18 are respectively sleeved on the outer surfaces of the plurality of movable rods 17. In this embodiment, under the elastic force of the second springs 18, the scraper strip 19 can be tightly attached to the inner surface of the container when it is inside the container.
[0032] Two limit rods are fixedly connected to the bottom outer surface of the connecting plate 3, and four threaded blocks 6 are movably sleeved on the outer surfaces of the two limit rods. In this embodiment, when the knob 23 drives the first forward and reverse screw rod 4 and the second forward and reverse screw rod 5 to rotate, the threaded blocks 6 slide on the outer surfaces of the limit rods, preventing the threaded blocks 6 from rotating with the rotation of the first forward and reverse screw rod 4 and the second forward and reverse screw rod 5.
[0033] The bottom outer surfaces of the two scrapers 19 are both inclined outer surfaces, and the bottom outer surfaces of the two scrapers 19 form an inverted eight-shape. In the present embodiment, the bottom outer surfaces of the two scrapers 19 are in an inverted eight-shape, so that when the scraper 19 enters the interior of the container, when the scraper 19 is slightly located outside the container, when the scraper 19 moves downward, the container contacts the bottom end of the scraper 19, so that the container can squeeze the bottom end of the scraper 19, causing the second spring 18 to compress.
[0034] Working principle: When the utility model is in use, the container that needs to be stirred is fixed. When fixing the container, the container is placed in the placement slot, and the first motor 11 is turned on. The first motor 11 drives the third positive and negative screw rod 10 to rotate. The rotation of the third positive and negative screw rod 10 drives the two threaded plates 12 to move in the direction of approaching each other. The movement of the two threaded plates 12 drives the two arc-shaped clamping plates 14 to move in the direction of approaching each other until the two arc-shaped clamping plates 14 conflict with the outer wall of the container. The arc-shaped clamping plates 14 will drive the container to move toward the middle end and compress the first spring 13 until the arc-shaped clamping plates 14 contact with the pressure sensor 15. When the arc-shaped clamping plates 14 contact with the pressure sensor 15, when the pressure sensor 15 senses a certain value, it sends a signal to the controller. The controller receives the signal and stops the first motor 11, thereby completing the fixing of the container to avoid damage to the container caused by excessive pressure. To avoid instability of the container during stirring caused by too little pressure, after the fixation is completed, the knob 23 is turned according to the diameter of the container. The knob 23 drives the first positive and negative screw rod 4 and the second positive and negative screw rod 5 to rotate, thereby driving the two threaded blocks 6 on the first positive and negative screw rod 4 and the second positive and negative screw rod 5 to move. When the two threaded blocks 6 move, the angle between the two inclined stirring rods 7 changes, thereby adjusting the position of the horizontal stirring rod 9, and turning on the electric push rod 21. The electric push rod 21 works so that the inclined stirring rod 7 and the horizontal stirring rod 9 are placed inside the container. The second motor 22 works and drives the fixing frame 2 so that the first positive and negative screw rod 4 and the second positive and negative screw rod 5 rotate as a whole, thereby causing the inclined stirring rod 7 and the horizontal stirring rod 9 to stir the medium inside the container, and during the stirring process, the scraper 19 is driven to rotate, and the scraper 19 scrapes the medium adhered to the inner wall of the container to improve the stirring effect.
[0035] The controller is an existing structure, and the control circuit can be implemented through simple programming by technicians in this field. It belongs to the common knowledge in this field. It is only used without modification, so the control method and circuit connection are not described in detail.
[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
