Description

Technical Field

[0001] This application relates to the field of clay toy production equipment, and in particular to a biaxial clay kneading machine. Background Technology

[0002] In the production of clay toys, the kneading machine plays a crucial pretreatment role. Through mechanical stirring and kneading, the kneading machine evenly mixes the raw materials used to produce clay toys with pigments, water and other additives to form a clay semi-finished product. The kneading machine also removes air bubbles from the clay semi-finished product, adjusting it to a fine, flexible and uniform density, thus improving the uniformity and plasticity of the raw material mixture.

[0003] There is a kneading machine for producing clay toys. In order to improve the kneading efficiency of raw materials, two sets of stirring mechanisms are installed in the mixing box. The two sets of stirring mechanisms are arranged in the same direction and side by side along the mixing box, and the components of the two sets of stirring mechanisms are the same. The stirring mechanism includes stirring blades and a driving device. The driving device drives the stirring blades to rotate along the mixing box, so as to achieve the purpose of stirring and mixing the raw materials located in the mixing box.

[0004] In practical applications, due to the large amount of raw materials put into the mixing tank, the mixed raw materials are subjected to extrusion force during the mixing process of the two sets of mixing blades, causing them to move towards the axial end face of the mixing blades. This results in some raw materials accumulating at both ends of the mixing blades along the length direction, making it impossible for the raw materials at both ends of the mixing blades to continue mixing. As a result, the mixed raw materials are unevenly mixed. To avoid the above problems, operators need to periodically remove the raw materials that have accumulated at both ends of the mixing blades along the length direction, which is complicated and has room for improvement. Utility Model Content

[0005] The purpose of this utility model is to improve the uniformity of the raw material mixing for producing clay toys and to enhance the stability of the raw material during kneading. This application provides a biaxial clay kneading machine.

[0006] To achieve the above objectives, the biaxial clay kneader provided in this application adopts the following technical solution:

[0007] A biaxial clay kneader includes a main frame, a mixing hopper mounted on the main frame, and a drive mechanism. The mixing hopper rotatably carries a main mixing blade and a secondary mixing blade along its width. The drive mechanism includes a main drive assembly and a secondary drive component. The main drive assembly is connected to the main mixing blade, and the secondary drive component is connected to the secondary mixing blade. The main drive assembly is also connected to the secondary drive component. Auxiliary mixing blades rotatably carry auxiliary mixing blades at both ends along the length of the mixing hopper. A rotating assembly is mounted on the main frame. The rotating assembly includes a hydraulic pusher cylinder. The output shaft of the hydraulic pusher cylinder is located at the centerline of the mixing hopper's width direction, offset towards the secondary mixing blade, and is movably connected to the mixing hopper.

[0008] Preferably, the main drive assembly includes a drive module and a drive gear, the drive gear being coaxially fixed with the main stirring blade, the drive module being connected to the drive gear, and the sub-drive component including a driven gear, the driven gear being coaxially fixed with the sub-stirring blade, and the driven gear meshing with the drive gear.

[0009] Preferably, a limiting assembly is provided on the main frame located at the driven gear. The limiting assembly includes a limiting seat, a cover seat, and a rotating bearing. The rotating bearing is coaxially fixed with the sub-stirring blade. The limiting seat and the cover seat enclose a limiting cavity that matches the outer contour of the rotating bearing. The limiting seat and the cover seat are detachably connected. When the stirring hopper is in the initial state, the rotating bearing is located in the limiting cavity.

[0010] Preferably, an annular limiting groove is provided in the limiting cavity, and the groove width of the annular limiting groove and the thickness tolerance of the rotating bearing are in a transition fit.

[0011] Preferably, a cover plate is hinged to the mixing hopper, and a magnetic lock is provided on the surface of the cover plate that abuts against the mixing hopper. When the magnetic lock is energized, the magnetic lock attracts the cover plate to the mixing hopper.

[0012] Preferably, the auxiliary stirring blade is located above the main stirring blade and the sub-stirring blade, and the auxiliary stirring blade is arranged perpendicular to the main stirring blade and the sub-stirring blade in terms of spatial position.

[0013] Preferably, the mixing hopper is provided with an arc-shaped protrusion in the area between the main mixing blade and the sub-mixing blade.

[0014] Compared with the prior art, this utility model provides a biaxial clay kneader, which has the following beneficial effects:

[0015] 1. The main drive assembly drives the main stirring blade to rotate along the mixing hopper. Since the main drive assembly is connected to the sub-drive component, and the sub-drive component is connected to the sub-stirring blade, the sub-stirring blade can follow the main stirring blade when it moves. This achieves the purpose of the main drive assembly driving the main stirring blade and the sub-stirring blade to stir the raw materials in the mixing hopper at the same time. Since the two ends of the mixing hopper along the length direction also rotate and support auxiliary stirring blades, when the main stirring blade and the sub-stirring blade move, the auxiliary stirring blades are able to rotate along the mixing hopper due to the power applied by the main stirring blade and the sub-stirring blade. This squeezes the raw materials at both ends of the mixing hopper into the area between the two sets of auxiliary stirring blades in the mixing hopper, reducing the amount of raw materials accumulated at both ends of the mixing hopper along the length direction. This plays a positive guiding role in improving the uniformity of the raw materials in the mixing hopper, and no additional power source needs to be installed for the two sets of auxiliary stirring blades.

[0016] 2. When it is necessary to discharge the raw materials in the mixing hopper, the hydraulic pusher cylinder can be controlled to extend the output shaft of the hydraulic pusher cylinder, thereby driving the mixing hopper to rotate along the main frame with the main mixing blade as the reference, so that the mixing hopper is in an inclined state, so that the operator can take out the raw materials in the mixing hopper.

[0017] 3. An additional cover plate is added to the mixing hopper, and the cover plate is magnetically locked to the mixing hopper without the need for other mechanical mechanisms to fix the cover plate, thereby improving the safety of the mixing hopper during the mixing process and reducing the amount of foreign matter entering the mixing hopper during the mixing process.

[0024] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0025] This application discloses a biaxial clay kneader. (Refer to...) Figure 1 , Figure 2 as well as Figure 3 A biaxial clay kneader includes a main frame 1, a mixing hopper 2 mounted on the main frame 1, and a drive mechanism 3. The mixing hopper 2 rotatably carries a main mixing blade 21 and a sub-mixing blade 22 along its width direction. The drive mechanism 3 includes a main drive assembly 31 and a sub-drive component 10. The main drive assembly 31 is connected to the main mixing blade 21, and the sub-drive component 10 is connected to the sub-mixing blade 22. The main drive assembly 31 is also connected to the sub-drive component 10. The mixing hopper 2 rotatably carries auxiliary mixing blades 4 at both ends along its length direction. A rotating assembly 5 is mounted on the main frame 1. The rotating assembly 5 includes a hydraulic pusher cylinder 51. The output shaft of the hydraulic pusher cylinder 51 is located at the centerline of the mixing hopper 2 in the width direction, offset from the sub-mixing blade 22. The output shaft of the hydraulic pusher cylinder 51 is movably connected to the mixing hopper 2.

[0026] Specifically, the main drive assembly 31 includes a drive module 311 and a drive gear 312. The drive gear 312 is coaxially fixed to the main stirring blade 21, and the drive module 311 is connected to the drive gear 312. The sub-drive component 10 includes a driven gear 101, which is coaxially fixed to the sub-stirring blade 22 and meshes with the drive gear 312.

[0027] The drive module 311 includes a drive motor 3111, a geared motor 3112, and a transmission assembly 3113. The drive motor 3111 is located on the main frame 1 on one side of the mixing hopper 2. A mounting frame 9 is installed on the main frame 1 between the drive motor 3111 and the mixing hopper 2. The geared motor 3112 is installed on the mounting frame 9.

[0028] Furthermore, the transmission assembly 3113 includes a first synchronous pulley 31131, a second synchronous pulley 31132, and a synchronous belt 31133. The first synchronous pulley 31131 is coaxially fixed with the output shaft of the drive motor 3111, the second synchronous pulley 31132 is coaxially fixed with the output shaft of the reduction motor 3112, and the synchronous belt 31133 is sleeved on the first synchronous pulley 31131 and the second synchronous pulley 31132. The output shaft of the reduction motor 3112 is coaxially fixed with the drive gear 312.

[0029] Therefore, when the output shaft of the drive motor 3111 moves, it will drive the synchronous belt 31133 to rotate. Since the synchronous belt 31133 is sleeved on the first synchronous pulley 31131 and the second synchronous pulley 31132, it will drive the second synchronous pulley 31132 to rotate, thereby driving the output shaft of the reduction motor 3112, which is coaxially fixed with the second synchronous pulley 31132, to rotate. The speed is reduced by the reduction motor 3112, and the power is output through the output shaft to drive the main stirring blade 21 to rotate.

[0030] Furthermore, since the driven gear 101 meshes with the driving gear 312, when the driving gear 312 rotates, it will drive the driven gear 101 to rotate, thereby driving the sub-stirring blade 22 to rotate along the stirring hopper 2. The sub-stirring blade 22 rotates in the opposite direction to the main stirring blade 21, thereby achieving the purpose of mixing, stirring and kneading the raw materials located in the stirring hopper 2.

[0031] Correspondingly, a support frame 8 is installed on the main frame 1 located between the drive gear 312 and the mixing hopper 2. A seated bearing 81 is installed on the support frame 8. The main mixing blade 21 is coaxially fixed with the inner ring of the seated bearing 81, so that the main mixing blade 21 can rotate smoothly along the seated bearing 81, thereby improving the stability of the main mixing blade 21 when rotating along the main frame 1.

[0032] Reference Figure 3 and Figure 4 A limiting component 6 is provided on the main frame 1 located at the driven gear 101. The limiting component 6 includes a limiting seat 61, a cover seat 62, and a rotating bearing 63. The rotating bearing 63 is coaxially fixed with the sub-stirring blade 22. The limiting seat 61 and the cover seat 62 enclose and form a limiting cavity that matches the outer contour of the rotating bearing 63. The limiting seat 61 and the cover seat 62 are detachably connected. When the stirring hopper 2 is in the initial state, the rotating bearing 63 is located in the limiting cavity.

[0033] It needs to be defined here that when the mixing hopper 2 is in a horizontal state, that is, when the output shaft of the hydraulic push cylinder 51 is in a retracted state, the mixing hopper 2 is in its initial state.

[0034] Specifically, the limiting seat 61 is installed on the support frame 8 near the driven gear 101. The limiting seat 61 has threaded holes at both ends along its length. When the cover seat 62 is closed on the limiting seat 61, the cover seat 62 can be locked on the limiting seat 61 by bolts, so that the sub-stirring blade 22 can rotate smoothly in the limiting cavity through the rotating bearing 63, thereby achieving the purpose of limiting the rotation of the sub-stirring blade 22, reducing the wobble of the sub-stirring blade 22 when it rotates along the mixing hopper 2, and ensuring that the driven gear 101 can always mesh with the driving gear 312. This effectively solves the problem that when the sub-stirring blade 22 rotates along the mixing hopper 2, the force on the sub-stirring blade 22 is too large, causing the driven gear 101 to skip teeth along the driving gear 312.

[0035] Furthermore, the rotating assembly 5 also includes a hinge seat 52 and a connecting sleeve 53. The hinge seat 52 is mounted on the main frame 1 and has a through hole along its width. The base of the hydraulic push cylinder 51 is inserted into the through hole through a pin, so that the hydraulic push cylinder 51 can swing along the hinge seat 52.

[0036] Correspondingly, a rotating shaft is fixed on the outer wall of the mixing hopper 2 between the main mixing blade 21 and the sub-mixing blade 22. The rotating shaft is located on the outer wall between the centerline of the mixing hopper 2 along the width direction and the sub-mixing blade 22. The connecting sleeve 53 is fixedly connected to the output shaft of the hydraulic push cylinder 51. The connecting sleeve 53 is sleeved on the rotating shaft and rotatably connected to the rotating shaft.

[0037] Therefore, after the raw materials in the mixing hopper 2 have been kneaded, the operator can loosen the bolts and remove the cover seat 62 along the limit seat 61. Then, the hydraulic push cylinder 51 is activated. The output shaft of the hydraulic push cylinder 51 will drive the mixing hopper 2 to rotate along the main frame 1 with the seated bearing 81 as the base point. During this process, the driven gear 101 is always engaged with the driving gear 312, so that the mixing hopper 2 is in an inclined state, so that the operator can take out the kneaded raw materials along the mixing hopper 2.

[0038] Similarly, after the raw material in the mixing hopper 2 is removed, the operator can control the output shaft of the hydraulic push cylinder 51 to retract. The output shaft of the hydraulic push cylinder 51 will drive the mixing hopper 2 to rotate until the rotating bearing 63 is on the limit seat 61. Then the cover seat 62 is closed on the limit seat 61. At this time, the limit bearing is located in the limit cavity. Then the cover seat 62 is fixed again with bolts.

[0039] On the other hand, an annular limiting groove is provided in the limiting cavity, and the annular limiting groove and its width are in a transition fit with the thickness tolerance of the rotating bearing 63. The annular limiting groove limits the rotation path of the rotating bearing 63 along the limiting cavity, thus preventing radial displacement of the sub-stirring blade 22 and the rotating bearing 63 when the sub-stirring blade 22 rotates.

[0040] Meanwhile, there are two sets of auxiliary stirring blades 4. The two sets of auxiliary stirring blades 4 are located at both ends of the mixing hopper 2 along the length direction. The auxiliary stirring blades 4 are located above the main stirring blade 21 and the sub-stirring blade 22, and the spatial position relationship between the auxiliary stirring blades 4 and the main stirring blade 21 and the sub-stirring blade 22 is perpendicular to each other.

[0041] The purpose is that when the main stirring blade 21 and the sub-stirring blade 22 are in motion, the auxiliary stirring blade 4 is rotated along the mixing hopper 2 by the power applied by the main stirring blade 21 and the sub-stirring blade 22, thereby squeezing the raw materials located at both ends of the mixing hopper 2 into the area of ​​the mixing hopper 2 located between the two sets of auxiliary stirring blades 4, reducing the amount of raw materials accumulated at both ends of the mixing hopper 2 along the length direction, and playing a positive guiding role in improving the uniformity of the raw materials in the mixing hopper 2, without the need to install an additional power source for the two sets of auxiliary stirring blades 4.

[0042] On the other hand, refer to Figure 5 The mixing hopper 2 is provided with an arc-shaped protrusion 23 in the area between the main mixing blade 21 and the sub-mixing blade 22. The arc-shaped protrusion 23 is integrally formed with the mixing hopper 2. The bottom of the mixing hopper 2 is lifted by the arc-shaped protrusion 23. When the main mixing blade 21 and the sub-mixing blade 22 rotate along the mixing hopper 2, when the raw material reaches the arc-shaped protrusion 23, the guiding effect of the arc-shaped protrusion 23 allows the raw material to quickly reach between the main mixing blade 21 and the sub-mixing blade 22, instead of accumulating at the bottom of the mixing hopper 2. This effectively solves the problem that the raw material in the blind zone cannot be completely kneaded because there is a blind zone between the main mixing blade 21 and the sub-mixing blade 22 during the kneading process.

[0043] In addition, refer to Figure 1 and Figure 2A cover plate 7 is hinged to the mixing hopper 2. A magnetic lock 71 is provided on the surface of the cover plate 7 that abuts against the mixing hopper 2. The cover plate 7 is connected to the mixing hopper 2 via a hinge, and the magnetic lock 71 is installed on the surface of the cover plate 7 away from the hinge. When the magnetic lock 71 is energized, it attracts the cover plate 7 to the mixing hopper 2. The addition of a cover plate 7 to the mixing hopper 2, and its attraction to the mixing hopper 2 via the magnetic lock 71, eliminates the need for other mechanical mechanisms to fix the cover plate 7. This improves the safety of the mixing hopper 2 during the mixing process and reduces the amount of foreign matter entering the mixing hopper 2 during mixing.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
