Description

Technical Field

[0001] This utility model relates to the field of etching agent production technology, and in particular to an apparatus for etching agent production. Background Technology

[0002] When using a dental phosphoric acid etching agent production device, the raw materials for making the phosphoric acid etching agent—phosphoric acid, water, and thickener—are placed inside a mixing tank in a certain proportion. Then, a motor drives the stirring rod to rotate, thoroughly mixing the raw materials. This method can effectively produce phosphoric acid etching agents.

[0003] The inventors discovered in their daily work that the production of dental phosphoric acid etching agents still has at least the following problems: When using the dental phosphoric acid etching agent production device, the raw materials for making the phosphoric acid etching agent—phosphoric acid, water, and thickener—are placed inside the mixing tank in a certain proportion, and then the stirring rod is driven by a motor to rotate and fully mix the raw materials. This can produce phosphoric acid etching agents very well. However, in actual use, after production is completed, the surface of the stirring rod may be contaminated with residual raw materials. Because the stirring rod is located on the top of the inner wall of the mixing tank, cleaning is quite troublesome. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an apparatus for producing etchants.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an apparatus for producing etching agent, comprising a stirring tank, a motor fixedly connected to the top of the stirring tank, a stirring rod provided at the output end of the motor, a feed inlet provided at the top of the stirring tank, a discharge outlet provided at the bottom of the stirring tank, a solenoid valve provided on the surface of the discharge outlet, a fixing device provided at the top of the stirring rod, a support device provided on one side of the stirring rod, the fixing device comprising a connecting cylinder, the connecting cylinder being fixedly connected to the output end of the motor, the connecting cylinder being sleeved on the top surface of the stirring rod, a fixing groove being formed on the inner wall of the connecting cylinder, a receiving groove being formed on the top surface of the stirring rod, a fixing strip being slidably connected to the inner wall of the receiving groove, and the fixing strip being slidably connected to the inner wall of the fixing groove.

[0006] The effect achieved by the above components is as follows: when using the fixing device, the top of the stirring rod is manually slid into the inside of the connecting cylinder, the fixing strip is controlled to slide out of the receiving groove, and then one end of the fixing strip is slid into the inside of the fixing groove. This makes it easy to restrict the stirring rod inside the connecting cylinder. Reverse operation makes it easy to disassemble the stirring rod, which makes it easy to clean the surface of the stirring rod.

[0007] Preferably, the top of the stirring rod is provided with a rectangular groove, and a rectangular block is slidably connected to the inner wall of the rectangular groove. The top of the rectangular block is fixedly connected to one side of the inner wall of the connecting cylinder.

[0008] The effect achieved by the above components is to slide the rectangular block into the interior of the rectangular groove, so that when the motor drives the connecting cylinder to rotate, the stirring rod can be driven to rotate through the connecting cylinder.

[0009] Preferably, a first spring is fixedly connected to one side of the inner wall of the storage groove, and the end of the first spring away from the storage groove is fixedly connected to one side of the fixing strip.

[0010] The effect achieved by the above components is that the first spring presses the fixing strip away from the inner wall of the storage groove, thereby making it easier to restrict one end of the fixing strip inside the fixing groove.

[0011] Preferably, a connecting groove is provided in the inner wall of the top of the stirring rod, and a connecting wire is provided in the inner wall of the connecting groove. One end of the connecting wire is slidably inserted into one side of the storage groove. The end of the connecting wire passing through the storage groove is fixedly connected to one end of the fixing strip. A rotating ring is fixedly connected to the end of the connecting wire away from the fixing strip. The rotating ring is rotatably sleeved on the surface of the top of the stirring rod.

[0012] The effect achieved by the above components is as follows: the rotating ring is manually controlled to rotate on the surface of the stirring rod, which causes the connecting wire to be pulled out of the connecting groove, thereby compressing the first spring and causing the fixing strip to move away from the fixing groove.

[0013] Preferably, the inner wall of the connecting cylinder is provided with a circular groove, and a cylinder is slidably connected to the inner wall of the circular groove. A notch is provided on one side of the inner wall of the cylinder, and a rubber ring is provided on the inner wall of the notch. The rubber ring is fixedly connected to the surface of the stirring rod.

[0014] The effect achieved by the above components is that the cylinder is manually controlled to slide out of the inside of the groove, thereby squeezing the rubber ring into the inside of the notch. This allows the top of the stirring rod to be covered by the cylinder, thus preventing the raw material from contacting the connection between the stirring rod and the connecting cylinder.

[0015] Preferably, the support device includes an arc-shaped block, which is fixedly connected to one side of the stirring rod. A sliding groove is provided on the top of the arc-shaped block, and an arc-shaped plate is slidably connected to the inner wall of the sliding groove.

[0016] The effect achieved by the above components is that when using the support device, the arc plate can be manually slid from the bottom of the arc block into the inside of the sliding groove, so that the stirring rod and the connecting cylinder can be set together through the arc plate.

[0017] Preferably, the arc-shaped plate has a positioning groove on its inner wall near the stirring rod. A rectangular plate is slidably connected to the inner wall of the positioning groove. A damping rod is fixedly connected to one side of the inner wall of the positioning groove. The end of the damping rod away from the positioning groove is fixedly connected to one side of the rectangular plate. A second spring is sleeved on the surface of the damping rod. One end of the second spring is fixedly connected to one side of the inner wall of the positioning groove. The end of the second spring near the damping rod is fixedly connected to one end of the rectangular plate.

[0018] The effect achieved by the above components is that the rectangular plate is pressed away from the positioning groove by the second spring, so that the rectangular plate is set at the bottom of the arc plate, which makes it easier to confine the arc plate inside the sliding groove.

[0019] Preferably, a positioning plate is fixedly connected to one side of the connecting cylinder, a positioning groove is provided on one side of the positioning plate, a rubber block is provided on the inner wall of the positioning groove, and one side of the rubber block is fixedly connected to one side of the arc plate.

[0020] The effect achieved by the above components is to squeeze the rubber block into the inside of the locking groove, which makes it easier to set the arc plate on one side of the connecting cylinder.

[0021] In this invention, by setting a fixing device, when using the fixing device, the top of the stirring rod is manually slid into the inside of the connecting cylinder, and the fixing strip is controlled to slide out of the receiving groove. Then, one end of the fixing strip is slid into the inside of the fixing groove. This makes it easy to restrict the stirring rod inside the connecting cylinder. Reverse operation makes it easy to disassemble the stirring rod, which makes it easy to clean the surface of the stirring rod. Attached Figure Description

[0027] Example 1, such as Figure 1-4 As shown, an apparatus for producing dental phosphoric acid etching agent includes a motor 2 fixedly connected to the top of a mixing tank 1, a stirring rod 3 at the output end of the motor 2, a feed inlet 4 at the top of the mixing tank 1, a discharge outlet 5 at the bottom of the mixing tank 1, a solenoid valve 6 on the surface of the discharge outlet 5, a fixing device 7 at the top of the stirring rod 3, and a support device 8 on one side of the stirring rod 3. When using the dental phosphoric acid etching agent production apparatus, the raw materials for making the phosphoric acid etching agent—phosphoric acid, water, and thickener—are placed inside the mixing tank 1 in a certain proportion. Then, the motor 2 drives the stirring rod 3 to rotate, thoroughly mixing the raw materials, thus producing the phosphoric acid etching agent effectively.

[0028] Reference Figure 2The fixing device 7 includes a connecting cylinder 701, which is fixedly connected to the output end of the motor 2. The connecting cylinder 701 is sleeved on the top surface of the stirring rod 3. A fixing groove 703 is formed on the inner wall of the connecting cylinder 701, and a receiving groove 705 is formed on the top surface of the stirring rod 3. A fixing strip 704 is slidably connected to the inner wall of the receiving groove 705. The fixing strip 704 is slidably connected to the inner wall of the fixing groove 703. When using the fixing device 7, the top of the stirring rod 3 is manually slid into the connecting cylinder 701, and the fixing strip 704 is controlled to slide out of the receiving groove 705, thereby sliding one end of the fixing strip 704 into the fixing groove 703. This facilitates the restriction of the stirring rod 3 within the connecting cylinder 701. Inside the 1, the reverse operation facilitates the disassembly of the stirring rod 3, making it easier to clean its surface. A rectangular groove 709 is formed at the top of the stirring rod 3. A rectangular block 710 is slidably connected to the inner wall of the rectangular groove 709. The top of the rectangular block 710 is fixedly connected to one side of the inner wall of the connecting cylinder 701. Sliding the rectangular block 710 into the rectangular groove 709 allows the stirring rod 3 to rotate when the motor 2 drives the connecting cylinder 701 to do so. A first spring 714 is fixedly connected to one side of the inner wall of the receiving groove 705. The end of the first spring 714 away from the receiving groove 705 is fixedly connected to one side of the fixing strip 704. The first spring 714 guides the stirring rod 3 away from the receiving groove 705. One side of the inner wall of the groove 705 presses against the fixing strip 704, thereby facilitating the confinement of one end of the fixing strip 704 within the groove 703. A connecting groove 706 is formed in the inner wall of the top of the stirring rod 3. A connecting wire 707 is provided on the inner wall of the connecting groove 706. One end of the connecting wire 707 is slidably inserted into one side of the receiving groove 705. The end of the connecting wire 707 passing through the receiving groove 705 is fixedly connected to one end of the fixing strip 704. A rotating ring 708 is fixedly connected to the end of the connecting wire 707 away from the fixing strip 704. The rotating ring 708 is rotatably sleeved on the surface of the top of the stirring rod 3. The rotating ring 708 can be manually controlled to rotate on the surface of the stirring rod 3, thus allowing the connecting wire 707 to be... Pulling out the connecting groove 706 compresses the first spring 714, causing the fixing strip 704 to move away from the fixing groove 703. The inner wall of the connecting cylinder 701 has a circular groove 711, and a cylinder 712 is slidably connected to the inner wall of the circular groove 711. A notch 713 is provided on one side of the inner wall of the cylinder 712, and a rubber ring 702 is provided on the inner wall of the notch 713. The rubber ring 702 is fixedly connected to the surface of the stirring rod 3. By manually controlling the cylinder 712 to slide out of the circular groove 711, the rubber ring 702 is squeezed into the notch 713. In this way, the top of the stirring rod 3 can be covered by the cylinder 712, thereby preventing the raw material from contacting the connection between the stirring rod 3 and the connecting cylinder 701.

[0029] Reference Figure 3 and Figure 4The support device 8 includes an arc-shaped block 801, which is fixedly connected to one side of the stirring rod 3. A sliding groove 802 is formed at the top of the arc-shaped block 801, and an arc-shaped plate 803 is slidably connected to the inner wall of the sliding groove 802. When using the support device 8, the arc-shaped plate 803 is manually slid from the bottom of the arc-shaped block 801 into the sliding groove 802, thus allowing the stirring rod 3 and the connecting cylinder 701 to be set together via the arc-shaped plate 803. A positioning groove 807 is formed on the inner wall of the arc-shaped plate 803 near the stirring rod 3, and a rectangular plate 808 is slidably connected to the inner wall of the positioning groove 807. A damping rod 809 is fixedly connected to one side of the inner wall of the positioning groove 807, and the end of the damping rod 809 away from the positioning groove 807 is fixedly connected to one side of the rectangular plate 808. A second spring 8 is sleeved on the surface of the damping rod 809. 10. One end of the second spring 810 is fixedly connected to one side of the inner wall of the positioning groove 807. The end of the second spring 810 near the damping rod 809 is fixedly connected to one end of the rectangular plate 808. The second spring 810 presses the rectangular plate 808 away from the positioning groove 807, so that the rectangular plate 808 is set at the bottom of the arc plate 803. This makes it easier to restrict the arc plate 803 inside the sliding groove 802. A positioning plate 804 is fixedly connected to one side of the connecting cylinder 701. A locking groove 805 is opened on one side of the positioning plate 804. A rubber block 806 is provided on the inner wall of the locking groove 805. One side of the rubber block 806 is fixedly connected to one side of the arc plate 803. The rubber block 806 is pressed into the locking groove 805, which makes it easier to set the arc plate 803 on one side of the connecting cylinder 701.

[0030] Working principle: When using the dental phosphoric acid etching agent production device, the raw materials for making the phosphoric acid etching agent—phosphoric acid, water, and thickener—are placed into the mixing tank 1 in a certain proportion. Then, the motor 2 drives the stirring rod 3 to rotate, thoroughly mixing the raw materials. This ensures efficient production of the phosphoric acid etching agent. When using the fixing device 7, the top of the stirring rod 3 is manually slid into the connecting cylinder 701, controlling the fixing strip 704 to slide out of the receiving groove 705. Then, one end of the fixing strip 704 is slid into the fixing groove 703. The first spring 714 presses the fixing strip 704 away from the inner wall of the receiving groove 705, thus confining one end of the fixing strip 704 inside the fixing groove 703. This facilitates the confinement of the stirring rod 3 inside the connecting cylinder 701, allowing the rectangular block 710 to slide into the rectangular groove 709. When the motor 2 drives the connecting cylinder 701 to rotate, the stirring rod 3 can be rotated through the connecting cylinder 701. Reverse operation facilitates the disassembly of the stirring rod 3, making it easier to clean its surface. The cylinder 712 is manually controlled to slide out of the circular groove. Inside 711, the rubber ring 702 is squeezed into the notch 713, allowing the top of the stirring rod 3 to be covered by the cylinder 712, thus preventing the raw material from contacting the connection between the stirring rod 3 and the connecting cylinder 701. When the stirring rod 3 needs to be disassembled, the rotating ring 708 is manually controlled to rotate on the surface of the stirring rod 3, which pulls the connecting wire 707 out of the connecting groove 706, thereby compressing the first spring 714, which moves the fixing strip 704 away from the fixing groove 703. When using the support device 8, it is manually... The arc-shaped plate 803 slides from the bottom of the arc-shaped block 801 into the interior of the sliding groove 802. The second spring 810 presses the rectangular plate 808 away from the positioning groove 807, so that the rectangular plate 808 is set at the bottom of the arc-shaped plate 803. This makes it easier to restrict the arc-shaped plate 803 inside the sliding groove 802 and press the rubber block 806 into the interior of the locking groove 805. This makes it easier to set the arc-shaped plate 803 on one side of the connecting cylinder 701. In this way, the stirring rod 3 and the connecting cylinder 701 can be set together by the arc-shaped plate 803.

[0031] It should be noted that all damping rods in this case are telescopic dampers, which can absorb energy during the extension and retraction process.
