Obviously, the described embodiments 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 creative work are within the scope of protection of the present invention. Example

[0037] like Figure 1~Figure 4 As shown, this embodiment proposes a wet paper-based friction material manufacturing equipment, including a frame 1, the outer surface of the frame 1 is fixedly connected to a mixer 2, a control panel 7 and a pellet machine assembly 8 by bolts, the lower end of the mixer 2 is fixedly connected to a mixing motor 4, the lower end outer surface of the mixer 2 is fixedly connected to a discharge pipe 9, the outer surface of the discharge pipe 9 is movably connected to a discharge rod 10 near the mixer 2, the upper end of the mixer 2 is rotatably connected to a cover 3, the control panel 7 is used to control the operation of various electrical structures of the entire equipment, the mixer 2 is also provided with a heating element for heating internal raw materials, the outer surface of one side of the mixer 2 is provided with a mixing structure 5, and the mixer 2 is provided with a reinforcing structure 6;

[0038] The reinforcement structure 6 includes a reciprocating component 61 and a reinforcement component 62. The reciprocating component 61 includes a reciprocating rod 611 rotatably arranged at the internal axis of the mixer 2. The outer surface of the reciprocating rod 611 is fixedly connected to a mixing and stirring blade 612. The upper and lower ends of the reciprocating rod 611 are provided with connecting grooves 613. An upper rod 614 is arranged between the interior of the upper connecting groove 613 and the cover body 3. A lower rod 615 is arranged between the interior of the lower connecting groove 613 and the output end of the mixing motor 4. A limiting block 616 is fixedly connected to the inner side of the top end of the lower connecting groove 613 corresponding to the interior of the reciprocating rod 611. A supporting kit 617 is movably sleeved on the outer surface of the reciprocating rod 611. A guide piece 619 is fixedly connected to the upper end of the supporting kit 617. A protruding rod 618 is fixedly connected to the outer surface of the reciprocating rod 611. A positioning rod 610 is fixedly connected between the supporting kit 617 and the inner wall of the mixer 2.

[0039] The connecting groove 613 is a regular hexagonal prism groove structure, the lower end of the upper rod 614 and the upper end of the lower rod 615 are matched with the connecting groove 613, the upper end of the upper rod 614 and the cover body 3 are connected by a bearing, and the reciprocating rod 611 moves up and down along the height direction of the upper rod 614 and the lower rod 615. The lower end of the guide piece 619 is an inclined chamfered structure, and the reciprocating rod 611 rotates together with the protruding rod 618 to realize the reciprocating rod 611 The rotation forms a reciprocating motion up and down; the limit block 616 and the support kit 617 are used to limit the reciprocating rod 611 to rotate. The lowest point where the reciprocating rod 611 falls, and the supporting kit 617 is also used to maintain the stability of the guide piece 619 to realize the reciprocating motion of the reciprocating rod 611. The lower end of the supporting kit 617 is higher than the mixing and stirring blades 612 and the higher part is greater than the maximum height difference of the reciprocating motion of the reciprocating rod 611. The number of the mixing and stirring blades 612 is several groups and distributed in a ring array. The lower rod 615 is rotatably connected to the mixer 2 through a bearing, and there is a mechanical seal between the two. The reciprocating rod 611 passes through the supporting kit 617 and there is a rotatable connection between the two.

[0040] In this embodiment, after the mixed material enters the interior of the mixer 2, the mixing motor 4 is first started through the control panel 7, and the mixing motor 4 drives the lower rod 615 to rotate, and the lower rod 615 drives the reciprocating rod 611 to rotate and run, and the reciprocating rod 611 rotates to drive the mixing and stirring blades 612 to stir and mix the raw materials, and the heating element heats the raw materials in the mixer 2. During the rotation of the reciprocating rod 611, the protruding rod 618 will move along the upper end of the guide piece 619, and under the movement of the protruding rod 618, the reciprocating rod 611 will follow and move upward. When the protruding rod 618 moves to the uppermost end of the guide piece 619, the reciprocating rod 611, the protruding rod 618 and the mixing and stirring blade 612 will fall to the lowest end under the action of gravity. Under the action of rotation, the reciprocating rod 611 will rotate upward again and fall, thereby forming a reciprocating operation effect of the reciprocating rod 611 moving up and down, so that the mixing and stirring blade 612 can fully stir the raw materials in different parts. Example

[0041] like Figure 1~Figure 4 As shown, on the basis of Example 1, it is further proposed that the reinforcing component 62 includes a recess 621 opened on the outer surface of the mixing stirring blade 612, the inner wall of the mixer 2 is fixedly connected with a fixing rod 622, one end of the fixing rod 622 is rotatably connected with a horizontal stirring blade 623, the middle part of the fixing rod 622 is rotatably connected with a vertical stirring blade 624, and the vertical stirring blade 624 and the horizontal stirring blade 623 are both provided with a through hole 625, and the mixing stirring blade 612 respectively beats the horizontal stirring blade 623 and the vertical stirring blade 624 to achieve stirring of the horizontal stirring blade 623 and the vertical stirring blade 624.

[0042] The horizontal stirring blades 623 and the vertical stirring blades 624 are both distributed in a ring array. The horizontal stirring blades 623 are rotated by being beaten by the kneading stirring blades 612, and the beating horizontal stirring blades 623 are the horizontal stirring blades 623 close to the reciprocating rod 611. During the up and down reciprocating motion of the kneading stirring blades 612, they never contact the horizontal stirring blades 623 and the upper ends of the fixed rod 622. The rotation radius of the vertical stirring blades 624 is equal to the opening height of the recess 621. The vertical stirring blades 624 can rotate forward and reversely by beating the vertical stirring blades 624 at the lower end or the vertical stirring blades 624 at the upper end through the up and down movement of the kneading stirring blades 612.

[0043] In this embodiment, while the mixing and stirring blades 612 are stirring the mixture by reciprocating up and down motion, each group of mixing and stirring blades 612 will hit the horizontal stirring blades 623 to force the horizontal stirring blades 623 to rotate to further stir the material body. At the same time, in the stirring range of the lower half of the mixing and stirring blades 612, the mixing and stirring blades 612 will hit the upper end of the vertical stirring blades 624, so that the vertical stirring blades 624 rotate forward to stir the material body in the positive longitudinal direction, while in the stirring range of the upper half of the mixing and stirring blades 612, the mixing and stirring blades 612 will hit the lower end of the vertical stirring blades 624, so that the vertical stirring blades 624 rotate forward to stir the material body in the reverse longitudinal direction, which can effectively enhance the mixing effect during the mixing process and thus effectively improve the mixing efficiency of the equipment. Example

[0044] like Figure 1~Figure 4 As shown, on the basis of Example 2, a mixing structure 5 is further proposed, which includes a feed pipe 51 fixedly connected to the outer surface of the mixer 2, one end of the feed pipe 51 is fixedly connected to a stirring chamber 52, the upper end of the stirring chamber 52 is fixedly connected to a distribution pipe 53, the interior of the stirring chamber 52 is rotatably connected to a mixing and stirring blade 54, the upper end of the distribution pipe 53 is fixedly connected to a feed bin 55, the interior of the feed bin 55 is fixedly connected to a partition plate 56, and the lower end of the feed bin 55 corresponds to each area separated by the partition plate 56. Only one group of feed holes 57 are respectively opened inside, and the feed holes 57 are respectively connected to the upper ends of a group of feed pipes 53, a movable plate 58 is movably arranged inside the feed bin 55, one end of the movable plate 58 is fixedly connected to a tip 59, and the other end of the movable plate 58 is clamped on the outer surface of the upper end of the feed bin 55, and an indicating scale 510 is opened on the outer surface of the feed bin 55, and the outer surfaces of the distribution pipe 53 and the feed pipe 51 are fixedly connected to a solenoid valve 511.

[0045] The upper end of the stirring bin 52 is fixedly connected to a driving motor, which drives the mixing and stirring blades 54 to stir and mix. The mixing and stirring blades 54 are two groups of stirring blades arranged in an upper and lower manner, and the movable plate 58 rotates along the circumference of the feed bin 55; the feed amount is adjusted by the size of the opening for falling formed between the movable plate 58 and the feed hole 57, and the opening ratio of multiple groups of feed holes 57 is adjusted by the relative position of the indicating scale 510 and one end of the movable plate 58. The upper end of the stirring bin 52 is fixedly connected to a motor, and the middle shaft of the mixing and stirring blades 54 is fixedly connected to the output end of the motor, and the solenoid valve 511 and the motor are both conductively connected to the control panel 7.

[0046] In this embodiment, the user will first rotate the movable plate 58 so that one end of the movable plate 58 corresponds to the appropriate position on the indicator scale 510 to form the feeding ratio, and then pour the prepared granular raw materials into each compartment of the internal partition plate 56 of the feed bin 55. During this process, the tip 59 is pressed against the bend of the partition plate 56, and the other end of the movable plate 58 rotates along the bearing of the feed bin 55, so as to maintain the rotation accuracy of the movable plate 58. Then, the device is started through the control panel 7, and the solenoid valve 511 on the feed pipe 53 is first controlled to open, so that the raw materials fall from the inside of the feed pipe 53 to the inside of the mixing bin 52. The motor is automatically started through the control panel 7 to drive the mixing and stirring blades 54 to rotate to perform preliminary mixing of the raw materials. After the mixing is completed, the solenoid valve 511 on the feed pipe 51 is automatically controlled to open through the control panel 7, so that the mixed material falls into the inside of the mixer 2.

[0047] Through the function of the above-mentioned mixing structure 5, the ratio of the raw materials can be adjusted in advance. By adjusting the opening of the raw materials through the feed hole 57 and controlling the ratio of more than two groups, it is possible to feed the raw materials at the same time without the need for precise weighing and adding the raw materials, thereby forming an automatic addition effect. At the same time, the raw materials can be premixed in advance, thereby effectively reducing the time of the subsequent mixing process.

[0048] The present invention also includes a method for using a wet paper-based friction material manufacturing device, and the specific method for using is as follows:

[0049] a. The raw material is pelletized by the pelletizer assembly 8;

[0050] b. First, rotate the movable plate 58 so that one end of the movable plate 58 corresponds to a suitable position on the indicator scale 510 to form a feed ratio, and then pour the prepared granular raw materials into each compartment of the internal partition plate 56 of the feed bin 55;

[0051] c. Start the equipment through the control panel 7, first control the solenoid valve 511 on the material distribution pipe 53 to open, so that the raw materials fall from the inside of the material distribution pipe 53 into the inside of the mixing chamber 52, and automatically start the motor through the control panel 7 to drive the mixing and stirring blades 54 to rotate to perform preliminary mixing of the raw materials. After the mixing is completed, the solenoid valve 511 on the feed pipe 51 is automatically controlled by the control panel 7 to open, so that the mixed material body falls into the inside of the mixer 2;

[0052] d. The mixing motor 4 is started through the control panel 7, driving the reciprocating rod 611 to rotate, mixing the mixed raw materials through the reinforcing structure 6, and heating the internal raw materials to form a mixing effect;

[0053] e. After the mixing is completed, the user presses the discharge rod 10 downward to obtain the mixed material through the discharge pipe 9.

[0054] In summary, when in use, the user first pelletizes the raw material through the pelletizer assembly 8;

[0055] Then, the premixing process is entered. The user will first rotate the movable plate 58 so that one end of the movable plate 58 corresponds to the appropriate position on the indicator scale 510 to form the feeding ratio. Then, the prepared granular raw materials are poured into each compartment of the internal partition plate 56 of the feed bin 55. During this process, the tip 59 is pressed against the bend of the partition plate 56, and the other end of the movable plate 58 rotates along the bearing of the feed bin 55 to maintain the accuracy of the rotation of the movable plate 58. Then, the device is started through the control panel 7. First, the solenoid valve 511 on the feed pipe 53 is controlled to open, so that the raw materials fall from the inside of the feed pipe 53 to the inside of the mixing bin 52. The motor is automatically started through the control panel 7 to drive the mixing and stirring blades 54 to rotate to perform preliminary mixing of the raw materials. After the mixing is completed, the solenoid valve 511 on the feed pipe 51 is automatically controlled to open through the control panel 7, so that the mixed material falls into the inside of the mixer 2.

[0056] Through the function of the mixing structure 5, the ratio of the raw materials can be adjusted in advance. By adjusting the opening of the feed hole 57 through which the raw materials pass and controlling the ratio of two or more groups, the raw materials can be added without accurate weighing while feeding at the same time, which can form an automatic addition effect. At the same time, the raw materials can be pre-mixed in advance, thereby effectively reducing the time of the subsequent mixing process.

[0057] After the mixed material enters the mixer 2, the mixer motor 4 is first started through the control panel 7, and the mixer motor 4 drives the lower rod 615 to rotate, and the lower rod 615 drives the reciprocating rod 611 to rotate, and the reciprocating rod 611 rotates to drive the mixing and stirring blades 612 to mix the raw materials, and the heating element heats the raw materials in the mixer 2. During the rotation of the reciprocating rod 611, the protruding rod 618 moves along the upper end of the guide piece 619, and under the movement of the protruding rod 618, the reciprocating rod 611 moves upward. When the reciprocating rod 611 moves partly upward along the upper rod 614 and the lower rod 615, and the kneading stirring blade 612 moves partly upward accordingly. When the protruding rod 618 moves to the uppermost end of the guide piece 619, under the action of gravity, the reciprocating rod 611 together with the protruding rod 618 and the kneading stirring blade 612 will fall to the lowest end. Under the action of rotation, the reciprocating rod 611 will rotate upward again and fall, thereby forming a reciprocating operation effect of the reciprocating rod 611 moving up and down, so that the kneading stirring blade 612 can fully stir the raw materials at different parts.

[0058] It should be noted that in the process of the mixing and stirring blades 612 reciprocating up and down to stir the mixture, each group of mixing and stirring blades 612 will slap the horizontal stirring blades 623 to force the horizontal stirring blades 623 to rotate to further stir the material body. At the same time, in the stirring range of the lower half of the mixing and stirring blades 612, the mixing and stirring blades 612 will slap the upper end of the vertical stirring blades 624, so that the vertical stirring blades 624 rotate forward to stir the material body in the positive longitudinal direction, and in the stirring range of the upper half of the mixing and stirring blades 612, the mixing and stirring blades 612 will slap the lower end of the vertical stirring blades 624, so that the vertical stirring blades 624 rotate forward to stir the material body in the reverse longitudinal direction, which can effectively enhance the mixing effect during the mixing process, and thus can effectively improve the mixing efficiency of the equipment.

[0059] It should be noted that when the mixing structure 5 is performing the mixing or feeding stage, the heating element inside the mixer 2 and the stirring effect of the reinforcing structure 6 can be started, so that the temperature area inside the mixer 2 is uniform, so that the material can be quickly mixed after entering the mixer 2, which can further improve the mixing efficiency.

[0060] After the mixing is completed, the user can press the discharging rod 10 downward to obtain the mixed material through the discharging pipe 9 .

[0061] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
