Description

Technical Field

[0001] The invention belongs to the technical field of ceramic clay processing equipment, and in particular relates to a double-drive clay kneading machine. Background Art

[0002] Clay kneading machine is an indispensable processing equipment in the production of ceramic and electrical porcelain clay. Its main function is to remove air and moisture from the clay, making the clay more uniform and dense, avoiding bubbles and cracks in the molding and firing process of ceramic or electrical porcelain, thereby ensuring the quality and stability of the finished product and improving the plasticity and formability of the clay.

[0003] Traditional mud kneading machines mainly use centralized drive (single motor drive), so traditional mud kneading machines have a large number of gears, and a large number of parts that need to be processed, which makes assembly and maintenance more difficult. And because the mud has a certain viscosity, it is easy to cause the starting load of the motor to be too large when the upper and lower shafts are started at the same time. And when the lower extrusion part and the upper feeding part become smaller due to the user's needs to fry the product, the pressure of the lower extrusion part increases, which slows down the extrusion speed of the lower mud, causing the vacuum box to be blocked. Or when the lower level is extruding, the upper level cannot stop because of the material stop, resulting in the mud being not compacted, causing the mud to leak air in the vacuum box, causing the mud to crack, and other problems such as reduced vacuum degree of other series vacuum equipment.

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0032] The present invention provides Figures 1 to 9A dual-drive mud kneading machine is shown, comprising an upper mounting frame 1 and a lower mounting frame 2, wherein the upper mounting frame 1 is horizontally fixedly connected to the top of the lower mounting frame 2, a feeding box 3 is fixedly mounted on the upper mounting frame 1, and a feeding port is arranged on the top of the feeding box 3, a transmission shaft 4 is rotatably inserted through one side of the feeding box 3, a discontinuous stirring blade group 5 is installed on the surface of the transmission shaft 4 located inside the feeding box 3, a first reducer 6 is connected to one end of the transmission shaft 4 located outside the feeding box 3, a first motor 7 is arranged on the front side of the first reducer 6, and the first motor 7 and the first reducer 6 are all installed on the upper mounting frame 1, and the first motor 7 and the first reducer 6 transmit power through a transmission belt. The side of the feeding box 3 away from the first reducer 6 is connected with a compression cone 8, the compression cone 8 is communicated with the feeding box 3, and a first spiral extrusion rod 9 matching the compression cone 8 is installed in the compression cone 8, the first spiral extrusion rod 9 is connected to the transmission shaft 4, and the compression cone 8 is connected to a vacuum box 10 at one end away from the feeding box 3. A connecting hole is opened at the position opposite to the vacuum box 10 and the first spiral extrusion rod 9, and a connecting hole is installed in the connecting hole. A circular feeding plate 11 is provided, and a plurality of feeding holes 12 are evenly opened between the two sides of the feeding plate 11. A cleaning assembly 13 is provided on the side of the feeding plate 11 away from the compression cone 8. An extrusion cylinder 14 is connected to the position near the bottom end of the side of the vacuum box 10 away from the compression cone 8. A second spiral extrusion rod 15 is installed in the extrusion cylinder 14. One end of the second spiral extrusion rod 15 located in the vacuum box 10 is connected to a drive shaft 16. The drive shaft 16 rotates vertically and penetrates and is inserted into the side of the vacuum box 10 close to the compression cone 8. The drive shaft 16 is away from the second spiral extrusion rod 15. One end of the second spiral extrusion rod 15 is connected to a second reducer 17, and a second motor 18 is arranged on the front side of the second reducer 17. The second motor 18 and the second reducer 17 are both mounted on the lower mounting frame 2, and the second motor 18 and the second reducer 17 also transmit power through a transmission belt. A continuous stirring knife group 19 is installed on the surface of the drive shaft 16 located in the vacuum box 10, and a blocking plate 20 is installed on the rear side box wall of the feeding box 3 and the rear inner wall of the vacuum box 10, and a plurality of anti-slip strips 21 are installed on the inner wall of the feeding box 3 and the inner wall of the vacuum box 10;

[0033] The blocking plate 20 is composed of a plurality of strip scrapers arranged side by side, and the distribution area of ​​the plurality of strip scrapers is parallel to the length direction of the transmission shaft 4 or the driving shaft 16. The anti-slip strips 21 on the inner wall of the feeding box 3 and the inner wall of the vacuum box 10 are respectively parallel to the transmission shaft 4 and the driving shaft 16, and the lengths of the blocking strips on the inner wall of the feeding box 3 and the inner wall of the vacuum box 10 match the internal lengths of the feeding box 3 and the vacuum box 10 respectively. The angle between the blades in the discontinuous stirring knife group 5 and the central axis of the transmission shaft 4 is 30°, and the projection width of the blades in the discontinuous stirring knife group 5 along the axis perpendicular to the central axis of the transmission shaft 4 is equal to the distance between two adjacent strip scrapers on the blocking plate 20 in the feeding box 3. The angle between the blades in the continuous stirring knife group 19 and the central axis of the driving shaft 16 is 25°, and the projection width of the blades in the continuous stirring knife group 19 along the axis perpendicular to the central axis of the driving shaft 16 is equal to the distance between two adjacent strip scrapers on the blocking plate 20 in the vacuum box 10.

[0034] When performing mud kneading operation, first start the first motor 7 and the second motor 18 in sequence. When the first motor 7 and the second motor 18 can respectively drive the transmission shaft 4 and the driving shaft 16 to rotate stably through the first reducer 6 and the second reducer 17, the mud material is added into the feeding box 3 through the feeding port on the top of the feeding box 3. Then, the discontinuous stirring knife group 5 in the feeding box 3 can fully crush and mix the mud material. Moreover, since the blades of the discontinuous stirring knife group 5 are inclined, the blades in the discontinuous stirring knife group 5 can be inclined during the rotation of the discontinuous stirring knife group 5. The mud material generates a thrust in the direction of approaching the compression cone 8, so that the discontinuous stirring blade group 5 can also play a role in conveying the mud material. In the process of the discontinuous stirring blade group 5 conveying the mud material into the compression cone 8, since the mud material itself has a certain plasticity, the mud material will follow the discontinuous stirring blade group 5 to make a circular rotation. When the mud material is turned to the area where the blocking plate 20 is located under the stirring of the discontinuous stirring blade group 5, the strip scraper on the blocking plate 20 can cut the mud material off from the discontinuous stirring blade group 5, thereby improving the discontinuous stirring blade group 5 The efficiency of crushing and mixing the mud material;

[0035] In addition, since the mud is conveyed in the form of a spiral when it is crushed and mixed, the anti-slip strip 21 on the inner wall of the feeding box 3 can limit the circular motion of the mud and promote the mud to be conveyed in a straight line along the length direction of the anti-slip strip 21, thereby improving the conveying efficiency of the mud. When the mud is conveyed to the inside of the compression cone 8, the first spiral extrusion rod 9 in the compression cone 8 can fully squeeze the mud and fill the compression cone 8. Then, as the mud in the compression cone 8 increases, the mud can contact the feeding plate 11 under the action of the first spiral extrusion rod 9, so that the mud can be cut into long and thin strips under the cutting action of the feeding hole 12 on the feeding plate 11, and then the cut mud can fall into the vacuum box 10;

[0036] Subsequently, the mud material falling into the bottom of the vacuum box 10 can be fully crushed, mixed and transported for the second time under the stirring action of the continuous stirring blade group 19. In this process, since the continuous stirring blade group 19 has a smaller angle with the drive shaft 16 than the discontinuous stirring blade group 5, the mud material can be cut and crushed more finely, thereby facilitating the vacuum box 10 to vacuum and degas it. In addition, since the vacuum box 10 is also provided with a baffle plate 20 and a slide-blocking strip 21, the cut mud material can move along a straight line into the extrusion barrel 14. When the mud material enters the extrusion barrel 14, the second spiral extrusion rod 15 can fully knead and squeeze the mud material to eliminate the spiral lines, and finally extrude it from the end of the extrusion barrel 14.

[0037] Compared with the existing mud kneading machines, the present invention realizes stirring and extruding of the mud material respectively by making the first motor 7 and the second motor 18 drive the transmission shaft 4 and the drive shaft 16 to rotate respectively, thereby avoiding the problems of excessive starting load of the motor of the existing mud kneading machine, too many transmission gears, a large number of processed parts, and difficult assembly and maintenance. At the same time, it also avoids the problem that when the second spiral extrusion rod 15 is extruding during the mud kneading process, the first spiral extrusion rod 9 cannot be stopped due to stopping the feeding, resulting in loose compression of the mud material, causing cracking of the mud material due to air leakage from the vacuum box 10, and reduced vacuum degree of other series vacuum equipment.

[0038] like Figures 6 to 9As shown, the cleaning assembly 13 includes a circular cleaning plate 131, the cleaning plate 131 is concentric and parallel to the feeding plate 11, and the side of the cleaning plate 131 close to the feeding plate 11 is evenly provided with plug blocks 132 matching the multiple feeding holes 12, and the length of the plug blocks 132 is the same as the depth of the feeding holes 12, a rotating shaft 133 is inserted through the center of the cleaning plate 131 and the feeding plate 11, the rotating shaft 133 is rotatably connected with the cleaning plate 131, and there is a gap between the feeding plate 11 and the rotating shaft 133, the end of the rotating shaft 133 away from the feeding plate 11 is rotatably inserted through the side of the vacuum box 10 away from the compression cone 8, and the end of the rotating shaft 133 away from the feeding plate 11 is connected to the third motor 134, and the part of the rotating shaft 133 located on the side of the cleaning plate 131 away from the feeding plate 11 is threadedly sleeved with a movable sleeve 135, The front and rear sides of the sleeve 135 are symmetrically fixedly connected with a fixing plate 136, and a limiting rod 137 parallel to the rotating shaft 133 is slidably inserted and inserted on the fixing plate 136, and the two ends of the limiting rod 137 are respectively fixedly connected to the inner walls of the two sides of the vacuum box 10, and a first rotating ring 138 is rotatably connected between the two fixing plates 136 close to the feeding plate 11, and the first rotating ring 138 is located between the two limiting rods 137, and a second rotating ring 139 is rotatably connected to the side of the feeding plate 11 close to the cleaning plate 131, and the second rotating ring 139 and the first rotating ring 138 are coaxial with the rotating shaft 133, and two pull rods 140 are vertically symmetrically fixedly connected between the opposite sides of the first rotating ring 138 and the second rotating ring 139, and notches are provided at the front and rear sides of the cleaning plate 131 opposite to the two pull rods 140, and the two pull rods 140 are slidably connected to the two notches respectively;

[0039] The end of the rotating shaft 133 close to the feeding plate 11 is slidably sleeved with a one-way shaft sleeve 22, and the one-way shaft sleeve 22 is rotatably installed at the center of the feeding plate 11. The inner side of the one-way shaft sleeve 22 is symmetrically fixedly connected with two limit blocks 23. The surface of the rotating shaft 133 is symmetrically provided with two strip-shaped limit grooves 24, and the limit grooves 24 are parallel to the length direction of the rotating shaft 133. The two limit blocks 23 are respectively slidably installed in the two limit grooves 24, and the one-way shaft sleeve 22 is away from the cleaning A plurality of scraper strips 25 are distributed in a ring on one side of the processing plate 131, and the scraper strips 25 are fixedly connected to the one-way sleeve 22, and the scraper strips 25 are in contact with the side of the feed plate 11 away from the cleaning plate 131. A plurality of spiral scrapers 26 are distributed in a ring on the side of the feed plate 11 away from the cleaning plate 131, and the scrapers 26 are fixedly connected to the feed plate 11, and the plurality of scrapers 26 are rotationally symmetrical about the rotating shaft 133, and the side of the scraper strips 26 away from the rotating shaft 133 is in contact with the inner wall of the connecting hole.

[0040] When the rotating shaft 133 starts to rotate under the drive of the third motor 134, the rotating shaft 133 can move along the rotating shaft 133 under the joint limiting action of the limiting rod 137 and the fixed plate 136. In this process, the movable sleeve 135 can pull the feeding plate 11 to move in the direction of the cleaning plate 131 through the fixed plate 136 and the pull rod 140. At the same time, as the rotating shaft 133 rotates, the rotating shaft 133 can drive the one-way shaft sleeve 22 and the feeding plate 11 to rotate together through the cooperation of the limiting groove 24 and the limiting block 23. As the feeding plate 11 rotates, the feeding plate 11 When the feed plate 11 is separated from the connecting hole, the spirally arranged scraper 26 can also scrape along the inner wall of the connecting hole, so that the mud remaining at the connecting hole is pushed off from the gap between the feed plate 11 and the connecting hole into the vacuum box 10, thereby preventing the mud remaining at the connecting hole from clogging the feed plate 11 after drying. During the rotation of the feed plate 11, the feed plate 11 and the cleaning plate 131 can keep rotating synchronously under the restriction of the pull rod 140, so that the plug 132 on the cleaning plate 131 will not deviate from the feed hole 12 on the feed plate 11.

[0041] As the feeding plate 11 moves along the rotating shaft 133, when the feeding plate 11 contacts the cleaning plate 131, the insert block 132 on the cleaning plate 131 can be inserted into the feeding hole 12, so as to eject the mud material remaining in the feeding hole 12, and then the third motor 134 is rotated in the reverse direction. As the third motor 134 rotates in the reverse direction, the rotating shaft 133 can drive the fixed plate 136, the pull rod 140 and the feeding plate 11 to gradually return to their original position through the movable sleeve 135. At the same time, as the rotating shaft 133 rotates in the reverse direction, the one-way The shaft sleeve 22 can idle and will not drive the feed plate 11 to rotate. As the one-way shaft sleeve 22 idles, the scraper bar 25 can scrape along the side of the feed plate 11 away from the cleaning plate 131, thereby scraping off the mud material just pushed out of the feed hole 12 by the plug block 132 from the feed plate 11, thereby preventing the mud material from sticking to the feed plate 11. As the rotating shaft 133 continues to rotate in the opposite direction, when the feed plate 11 re-enters the connecting hole, the third motor 134 stops, and the feed plate 11 completes the resetting operation again.

[0042] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
