Description

Technical Field

[0001] This utility model relates to the field of leather treatment agent production technology, specifically to a mixer for producing leather treatment agents. Background Technology

[0002] Leather treatment agents are chemical substances used to improve the properties, appearance, or feel of leather. They play a key role in the leather manufacturing and processing process. Various treatment agents are widely used in leather tanning, dyeing, finishing, and other processes to improve the quality and added value of leather and produce leather products that meet different needs, such as shoe upper leather, clothing leather, and furniture leather.

[0003] A mixer is needed in the production process of leather treatment agents. Utility model patent CN217511695U discloses a mixing device for a disperser, including a disperser support, a controller on one side of the disperser support, an electric lift at the other end of the disperser support, a disperser moving structure at one end of the disperser support, a rotating disperser motor on the outer wall of the moving structure, a disperser rotating rod at the bottom of the rotating disperser motor, a dispersion splash-proof structure on the outer wall of the disperser rotating rod, a stainless steel dispersion impeller at the bottom of the disperser rotating rod, a disperser base at the bottom of the disperser support, and a dispersion container fixing structure at the top of the disperser base. This utility model, by setting a dispersion splash-proof structure, allows a moving ring to slide on the disperser rotating rod, causing the splash-proof cover to move accordingly. The fixed threaded rod, through the moving ring, abuts against the disperser rotating rod, fixing the splash-proof cover in place, thus achieving the dispersion splash-proof function.

[0004] However, when using the stirring device of this disperser, if the dispersing impeller is placed into the container due to a calculation error, the dispersing impeller is prone to hitting the bottom of the container, causing damage to both the container and the dispersing impeller. Therefore, a mixer for the production of leather treatment agents is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mixer for the production of leather treatment agents, which has advantages such as preventing the mixing disc from hitting the bottom. It solves the problem that when the mixing device of a common disperser is used, the dispersing impeller is easily hit by the bottom of the container when it is placed in the container, causing damage to both the container and the dispersing impeller.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A mixer for producing leather treatment agents includes a mounting base plate, a lifting hydraulic cylinder fixedly mounted on the top of the mounting base plate, a transmission box fixedly mounted on the movable end of the lifting hydraulic cylinder, a stirring shaft rotatably mounted on the inner top wall of the transmission box, and an anti-bottom-touching component provided on the stirring shaft. The anti-bottom-touching assembly includes an inner rod that passes through the inside of the stirring shaft. An arc-shaped block is fixedly installed at the bottom end of the inner rod, and a top plate is fixedly installed at the top end of the inner rod. A pull-down spring is fixedly installed at the bottom of the top plate. A mounting shell is fixedly installed on the top of the transmission box, and a stop switch aligned with the top plate is fixedly installed on the inner bottom wall of the mounting shell.

[0007] Furthermore, the bottom end of the stirring shaft is bolted to a stirring turntable, the arc-shaped block is located below the stirring turntable, and the top plate is located above the transmission box.

[0008] Furthermore, a mounting arc plate is fixedly installed on one side of the transmission box, and a fixed junction box is fixedly installed on one side of the mounting arc plate.

[0009] Furthermore, an emergency stop branch line is fixedly installed on the top of the fixed junction box, and one end of the emergency stop branch line is fixedly connected to the stop switch.

[0010] Furthermore, a drive motor is fixedly installed at the bottom of the transmission box, and a drive sprocket is rotatably installed on the inner bottom wall of the transmission box. The output shaft of the drive motor is fixedly connected to the drive sprocket.

[0011] Furthermore, a driven sprocket is fixedly mounted on the surface of the transmission box on the stirring shaft, and the driving sprocket and the driven sprocket are connected by a drive chain.

[0012] Furthermore, a guide tube is fixedly installed at the bottom of the transmission box, through which the stirring shaft rotates. A limit plate is fixedly installed at the fixed end of the lifting hydraulic cylinder, and a linear bearing is fixedly installed at the top of the limit plate. A limit guide rod is slidably connected inside the linear bearing, and the top end of the limit guide rod is fixedly connected to the bottom of the transmission box.

[0013] Furthermore, a control box is fixedly installed on the top of the mounting base plate, a main cable is fixedly installed on one side of the control box, the main cable is connected to a fixed junction box, and a motor branch line is fixedly installed at the bottom of the fixed junction box, the motor branch line is connected to a drive motor.

[0014] Compared with the prior art, the present invention provides a mixer for the production of leather treatment agents, which has the following beneficial effects: 1. This mixer for producing leather treatment agents uses an inner rod inserted inside the mixing shaft. An arc-shaped block is installed at the bottom of the inner rod. When the mixing shaft is inserted into the mixing container, the arc-shaped block contacts the bottom of the container, pushing the inner rod upward. This causes the top plate to move upward and contact the stop switch, triggering the stop switch and closing the lifting hydraulic cylinder. This prevents the mixing disc from hitting the bottom, thus solving the problem that common dispersing machines often cause the dispersing impeller to hit the bottom of the container when it is placed in the container, resulting in damage to both the container and the dispersing impeller.

[0015] 2. The mixer used for producing leather treatment agents has a fixed junction box on one side of the transmission box. The wiring is connected to the stop switch and drive motor through the fixed junction box. When the stop switch and drive motor move up and down, the wiring is fixed. The main cable with reserved slack is connected to the control box to keep the circuit of the stop switch and drive motor unobstructed. Attached Figure Description

The output shaft of the drive motor 15 is fixedly connected to the drive sprocket 16.

[0026] The driven sprocket 17 is fixedly mounted on the surface of the transmission box 3 on the stirring shaft 4. The driving sprocket 16 and the driven sprocket 17 are connected by a drive chain 18. The drive motor 15 drives the driving sprocket 16 to rotate, which in turn drives the driven sprocket 17 to rotate via the drive chain 18, thereby driving the stirring shaft 4 to rotate and the stirring turntable 11 to rotate.

[0027] Meanwhile, a guide tube 19 is fixedly installed at the bottom of the transmission box 3. The stirring shaft 4 rotates through the guide tube 19. A limit plate 20 is fixedly installed at the fixed end of the lifting hydraulic cylinder 2. A linear bearing 21 is fixedly installed at the top of the limit plate 20. A limit guide rod 22 is slidably connected inside the linear bearing 21. The top end of the limit guide rod 22 is fixedly connected to the bottom of the transmission box 3. The connection between the limit guide rod 22 and the linear bearing 21 makes the lifting of the transmission box 3 more stable.

[0028] Among them, a control box 23 is fixedly installed on the top of the mounting base plate 1, a main cable 24 is fixedly installed on one side of the control box 23, the main cable 24 is connected to the fixed junction box 13, and a motor branch line 25 is fixedly installed at the bottom of the fixed junction box 13, the motor branch line 25 is connected to the drive motor 15.

[0029] The working principle of the above embodiment is as follows: the lifting hydraulic cylinder 2 drives the transmission box 3 to move down, which drives the stirring shaft 4 to extend into the stirring container. The arc-shaped block 6 contacts the bottom of the container and pushes the inner rod 5 upward until the top plate 7 contacts the stop switch 10, thus closing the lifting hydraulic cylinder 2.
