Technical Field
[0001] This utility model relates to the technical field of feeding devices for the production of paper stabilizers, specifically a feeding device for the production of paper stabilizers that facilitates feeding control. Background Art
[0002] Paper stabilizers are chemical substances used to improve various chemical and physical properties during paper manufacturing. These stabilizers are mainly used to control paper quality, ensure the stability of the production process, and the quality of the final product. In the production process of paper stabilizers, various raw materials need to be mixed first, and then fed into a reaction vessel through a conveying device to form the finished stabilizer. The feeding of raw materials requires a feeding device. Existing feeding devices for paper stabilizer production mainly consist of a silo and a mixing device. The silo has a stirring rack inside, driven by a motor. After the raw materials enter the silo, they are mixed by the stirring rack in the middle, and then directly fed into the conveying device through the outlet. Traditional feeding devices for paper stabilizer production simply mix the raw materials and then directly feed them into the conveying device to the next process. The mixing process is too short, easily leading to uneven mixing. The feeding amount is fixed and cannot be adjusted according to actual conditions. Therefore, we propose a feeding device for paper stabilizer production that allows for convenient control of the feeding process. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for the production of paper stabilizers that facilitates feeding control, comprising a mixing chamber and a feeding mechanism;
[0005] Mixing bin: It has a hopper at the top center, a feeding port at the bottom center of the mixing bin, and a chute at the bottom center of the mixing bin.
[0006] Feeding mechanism: It includes a baffle, spring, lead screw, connecting shaft and cam. The baffle is slidably connected to the inside of the chute. A spring is provided between the left end of the baffle and the inner wall of the chute. The lead screw is slidably connected to the right side of the bottom wall of the mixing chamber. The left side of the outer surface of the lead screw is threaded to the inside of the baffle. The connecting shaft is rotatably connected to the middle right side of the mixing chamber. The cam is set at the lower end of the connecting shaft. The outer edge of the cam is fitted with the right end of the lead screw, providing a basis for adjusting the feeding amount and opening and closing the discharge port. It can adjust the feeding amount by changing the position of the lead screw according to the actual situation, and can also control the opening and closing of the discharge port by changing the position of the lead screw, which facilitates the uniform mixing of raw materials.
[0007] Furthermore, the feeding mechanism also includes a drive assembly, which includes a central shaft, a motor, and pulleys. The central shaft is rotatably connected to the inside of the hopper, and the motor is located at the upper center of the hopper. The input end of the motor is electrically connected to the output end of the microcontroller, and the lower end of the motor's output shaft is fixedly connected to the upper end of the central shaft. Both the connecting shaft and the upper end of the central shaft are equipped with pulleys. The diameter of the right pulley is larger than that of the left pulley, and the two pulleys are connected by belt drive, providing a foundation for the feeding operation.
[0008] Furthermore, the feeding mechanism also includes a spiral blade, which is disposed on the upper part of the outer surface of the central shaft. The outer edge of the spiral blade is fitted with the inner wall of the hopper to make the raw material fall more smoothly and prevent blockage.
[0009] Furthermore, the feeding mechanism also includes a stirring plate, which is uniformly arranged on the lower end of the outer surface of the central shaft. The outer edge of the stirring plate is fitted with the inner wall of the mixing chamber to facilitate the mixing of raw materials.
[0010] Furthermore, both the mixing chamber and the material hopper have sloping walls to facilitate the falling of raw materials.
[0011] Furthermore, the tilt angles of every two vertically adjacent stirring blades are opposite, and the diameters of the three stirring blades decrease from top to bottom, further improving the mixing efficiency.
[0012] Furthermore, it also includes a microcontroller, which is located at the front center of the mixing chamber. The input terminal of the microcontroller is electrically connected to an external power source to provide a basis for the feeding operation.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This feeding device for the production of paper stabilizers, which facilitates feeding control, has the following advantages:
[0014] 1. By rotating the lead screw to change its position, when the right end of the lead screw is outside the radius of the cam, the cam cannot contact the right end of the lead screw, and the feeding port is always in a closed state, which facilitates the mixing of raw materials inside the mixing chamber.
[0015] 2. When the right end of the lead screw is located at the rotation radius of the cam, the baffle will move left and right with the rotation of the cam, thereby opening and closing the feeding port. When it is necessary to adjust the output, simply rotate the lead screw to move it. The more the lead screw moves to the right, the longer the movement of the baffle, the larger the opening of the feeding port, and the larger the output. Conversely, the smaller the output, the smaller the output. The output can be changed quickly. Attached Figure Description

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] Please see Figure 1-3 This embodiment provides a technical solution: a feeding device for the production of paper stabilizers that is easy to control, including a mixing chamber 1 and a feeding mechanism 4;
[0022] Mixing bin 1: It has a material bin 2 in the middle of its upper end for easy addition of raw materials. The bottom wall of mixing bin 1 has a feeding port in the middle for easy discharge. The bottom wall of mixing bin 1 has a chute 3 in the middle. The walls of mixing bin 1 and material bin 2 are both inclined walls to facilitate the falling of raw materials. It also includes a microcontroller 5, which is located in the middle of the front end of mixing bin 1. The input terminal of microcontroller 5 is electrically connected to an external power supply to provide a basis for feeding.
[0023] Feeding mechanism 4 includes a baffle 41, a spring 42, a lead screw 43, a connecting shaft 44, and a cam 45. The baffle 41 is slidably connected to the inside of the chute 3. A spring 42 is provided between the left end of the baffle 41 and the inner wall of the chute 3. The lead screw 43 is slidably connected to the right side of the bottom wall of the mixing chamber 1. The left side of the outer surface of the lead screw 43 is threaded to the inside of the baffle 41. The connecting shaft 44 is rotatably connected to the middle right side of the mixing chamber 1. The cam 45 is located at the lower end of the connecting shaft 44. The outer edge of the cam 45... Installed in conjunction with the right end of the lead screw 43, providing a basis for adjusting the feeding amount and opening and closing the discharge port. The feeding mechanism 4 also includes a drive assembly 46, which includes a central shaft 461, a motor 462, and a pulley 463. The central shaft 461 is rotatably connected to the middle of the inside of the hopper 2. The motor 462 is located at the upper middle of the hopper 2. The input end of the motor 462 is electrically connected to the output end of the microcontroller 5. The lower end of the output shaft of the motor 462 is fixedly connected to the upper end of the central shaft 461. The connecting shaft 44 and the central shaft 461 are connected to the central shaft 461. Each shaft 461 has a pulley 463 at its upper end. The diameter of the right pulley 463 is larger than that of the left pulley 463, which can create a transmission effect. The two pulleys 463 are connected by belt drive, providing a basis for feeding. The feeding mechanism 4 also includes a spiral blade 47, which is set on the upper part of the outer surface of the central shaft 461. The outer edge of the spiral blade 47 is installed in conjunction with the inner wall of the hopper 2, so that the raw material falls more smoothly and prevents blockage. The feeding mechanism 4 also includes a stirring blade 48, which is set on the lower part of the outer surface of the central shaft 461. The outer edge of the stirring blade 48 is installed in conjunction with the inner wall of the mixing hopper 1, which facilitates the mixing of raw materials. The inclination angles of vertically adjacent stirring blades 48 are opposite. The diameters of the three stirring blades 48 decrease from top to bottom, which further improves the mixing efficiency. The feeding amount can be adjusted by changing the position of the screw 43 according to the actual situation. The opening and closing of the discharge port can also be controlled by changing the position of the screw 43, which facilitates the uniform mixing of raw materials.
[0024] The working principle of the feeding device for paper stabilizer production provided by this utility model is as follows: During feeding, the raw materials are first mixed. The screw 43 is rotated forward, causing it to move to the left until its right end no longer contacts the outer edge of the cam 45's protrusion. At this point, the feeding port is closed. Then, the raw materials are added into the hopper 2. The microcontroller 5 controls the motor 462 to operate. The output of the motor 462 drives the central shaft 461 to rotate, and the spiral blades 47 also rotate, evenly conveying the raw materials downwards to prevent blockage of the hopper 2. After the raw materials enter the mixing chamber 1, the central shaft 461 drives the stirring blades 48 to rotate. The three stirring blades 48 mix the raw materials evenly. As the central shaft 461 continues to rotate, the left pulley 463 also rotates synchronously. Because the diameter of the right pulley 463 is larger than that of the left pulley 463, the two pulleys 463 are driven by the belt to form a transmission effect. The pulley 463 also rotates synchronously, and the connecting shaft 44 rotates accordingly, driving the cam 45 to rotate. Since the right end of the lead screw 43 has separated from the outer edge of the protruding part of the cam 45, the baffle 41 will not shift, and the feeding port is in a closed state. After the raw materials inside the mixing chamber 1 are evenly mixed, the lead screw 43 is reversed according to the actual situation, so that the lead screw 43 moves to the right until the right end of the lead screw 43 is located at the rotation radius of the cam 45. At this time, as the cam 45 rotates, the protruding part of the cam 45... When the right end of the screw 43 is pressed, the baffle 41 moves to the left, the spring 42 is compressed, the feed port opens, and the raw material falls from the feed port. When the protruding part of the cam 45 leaves the right end of the screw 43, the spring 42 is no longer compressed and rebounds, the baffle 41 returns to its original position, and the feed port closes. When it is necessary to adjust the output, simply rotate the screw 43 to move it. The more the screw 43 moves to the right, the longer the travel of the baffle 41, the larger the feed port opens, and the larger the output. Conversely, the output is smaller when the screw 43 moves to the right.
[0025] It is worth noting that the microcontroller 5 disclosed in the above embodiments is an S7-200 microcontroller, and the motor 462 is a YE4 motor. The microcontroller 5 controls the operation of the motor 462 using methods commonly used in the prior art.
[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
