Description

Technical Field

[0001] The utility model belongs to the technical field of pottery-making equipment, and particularly relates to an outlet of a clay kneading machine with adjustable size. Background Technique

[0002] Clay kneading is a key process in making pottery and porcelain. It is to expel the air in the clay completely by means of pounding and extrusion. Usually, a clay kneading machine is used to knead the clay.

[0003] However, the size of the outlet of the traditional clay kneading machine is fixed at the time of factory. With the continuous increase of product categories, users can only replace the outlet with different sizes according to different product sizes, which is time-consuming and laborious. Secondly, the traditional outlet does not have the ability of sealing. Whenever the machine is used up, the outlet must be sealed to prevent the raw material (clay) from drying and hardening due to the evaporation of moisture at the outlet, resulting in the extrusion of the raw material inside the machine and the cracking of the product during the later firing process due to the presence of dry and hard raw material in the finished raw material. The use process is rather laborious. Therefore, it is necessary to design an outlet of a clay kneading machine with adjustable size to solve the above problems. Content of the Utility Model

Detailed implementation manners

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] As Figures 1 to 3 shown, a size-adjustable outlet of a clay kneading machine according to an embodiment of the present invention includes a conical cylinder 1, a fixing plate 2, a sliding block 3 and a rotating gear disk 5. A convex male mouth 23 is provided on the fixing plate 2. The fixing plate 2 is arranged at the outlet of the conical cylinder 1, and the convex male mouth 23 communicates with the outlet of the conical cylinder 1;

[0025] Six sliding blocks 3 are provided. The six sliding blocks 3 are circumferentially distributed on the fixing plate 2. The rotating gear disk 5 is connected to the fixing plate 2. The six sliding blocks 3 are located between the fixing plate 2 and the rotating gear disk 5, and the rotating gear disk 5 rotates relative to the fixing plate 2;

[0026] A sliding pin 4 is installed on the sliding block 3. A straight groove 51 is formed on the rotating gear disk 5. One end of the sliding pin 4 is inserted into the straight groove 51 and is slidably connected to the straight groove 51.

[0027] Specifically, the conical cylinder 1, the fixing plate 2 and the rotating gear disk 5 are coaxially arranged. Secondly, six straight grooves 51 are evenly circumferentially distributed on the rotating gear disk 5, and the six sliding pins 4 are correspondingly inserted into the six straight grooves 51.

[0028] In this embodiment, the rotating gear disc 5 rotates, thereby driving the straight groove 51 on the rotating gear disc 5 to rotate. One end of the sliding pin 4 is inserted into the straight groove 51 and slides therein, so that the rotating gear disc 5 can drive the sliding pin 4 to rotate and move in the radial direction of the fixed plate 2 at the same time. Since the sliding pin 4 is installed on the sliding block 3, the sliding block 3 also rotates and moves in the radial direction of the fixed plate 2 at the same time. The sliding block 3 seals or opens outlets of different specifications and sizes for the convex sub-mouth 23.

[0029] Thus, by rotating the rotating gear disc 5, driving the sliding pin 4 to slide in the straight groove 51, six sliding blocks 3 move inward in the radial direction of the fixed plate 2 to seal the convex sub-mouth 23, which can effectively prevent the raw materials from drying out and hardening due to water evaporation, making the use process more convenient.

[0030] Secondly, when the rotating gear disc 5 rotates and drives the six sliding blocks 3 to move outward in the radial direction of the fixed plate 2, the convex sub-mouth 23 is opened, and outlets of different sizes can be set according to different product sizes and specifications, making the use process more convenient.

[0031] Optionally, as Figure 2 shown, a hexagonal limiting groove 21 is formed in the fixed plate 2, and the six sliding blocks 3 are all arranged in the hexagonal limiting groove 21.

[0032] Specifically, one end of the rotating gear disc 5 is located in the hexagonal limiting groove 21.

[0033] In this embodiment, by forming a hexagonal limiting groove 21 in the fixed plate 2 and arranging the six sliding blocks 3 in the hexagonal limiting groove 21, the six sliding blocks 3 can be prevented from separating from the fixed plate 2.

[0034] Optionally, as Figure 2 shown, a hexagonal sliding groove 22 is formed on the bottom surface of the hexagonal limiting groove 21, and the other end of the sliding pin 4 is inserted into the hexagonal sliding groove 22 and slides along the contour of the hexagonal sliding groove 22.

[0035] In this embodiment, by forming a hexagonal sliding groove 22 on the bottom surface of the hexagonal limiting groove 21 and inserting the end of the sliding pin 4 into the hexagonal sliding groove 22, the movement track of the sliding pin 4 is limited by the contour of the hexagonal sliding groove 22 to ensure the stability of the movement of the sliding pin 4, so that the six sliding blocks 3 can stably perform the opening and closing actions.

[0036] Optionally, as Figure 2As shown, a concave female opening 11 is provided at the outlet of the conical cylinder 1, and the convex male opening 23 is positioned and connected to the concave female opening 11.

[0037] Specifically, the convex male opening 23 and the concave female opening 11 are coaxially arranged. The protruding part of the convex male opening 23 is inserted into the recessed part of the concave female opening 11, and the fixing plate 2 and the conical cylinder 1 are connected by bolts.

[0038] In this embodiment, by providing the convex male opening 23 on the fixing plate 2 and the concave female opening 11 on the conical cylinder 1, and using the docking of the convex male opening 23 and the concave female opening 11, the fixing plate 2 and the conical cylinder 1 can be accurately docked, thereby realizing the positioning of the fixing plate 2 and the conical cylinder 1.

[0039] Optionally, as Figure 2 shown, six sliding blocks 3 are evenly distributed circumferentially on the fixing plate 2. A convex groove 31 is provided on one side surface of the sliding block 3, and a concave groove 32 is provided on the other side surface of the sliding block 3. Between two adjacent sliding blocks 3, the convex groove 31 of one sliding block 3 is slidably connected to the concave groove 32 of the other sliding block 3.

[0040] Specifically, the sliding block 3 is arranged in a pentagonal structure.

[0041] In this embodiment, among the six sliding blocks 3, between two adjacent sliding blocks 3, the side surface with the convex groove 31 on one sliding block 3 is attached to the side surface with the concave groove 32 on the other sliding block 3, and the convex groove 31 slides in the concave groove 32, making the mutual sliding of the six sliding blocks 3 smoother and less likely to shake, which is beneficial to improving the stability of the movement between the six sliding blocks 3.

[0042] Optionally, as Figure 1 and Figure 2 shown, the outlet of the size-adjustable clay kneading machine further includes a locking ring 7 and a driving mechanism 6. The locking ring 7 is connected to the fixing plate 2 by bolts and is located outside the rotating gear disc 5. The driving mechanism 6 is connected to the locking ring 7, and the driving mechanism 6 is in transmission connection with the rotating gear disc 5.

[0043] In this embodiment, by providing the locking ring 7, it is convenient to install the driving mechanism 6. And by providing the driving mechanism 6, the driving mechanism 6 can be used to drive the rotating gear disc 5 to rotate, saving manpower.

[0044] Optionally, as Figure 1 and Figure 2As shown, the driving mechanism 6 includes a driving motor 61 and a driving gear 62. The driving motor 61 is installed on the locking ring 7. A sawtooth is provided on the outer sidewall of the rotating gear disk 5. The driving gear 62 meshes with the sawtooth on the outer sidewall of the rotating gear disk 5. A certain gap is left between the upper plane of the locking ring 7 and the rotating gear disk 5.

[0045] In this embodiment, the driving mechanism 6 drives the driving gear 62 to rotate. By using the meshing of the driving gear 62 with the sawtooth on the outer sidewall of the rotating gear disk 5, the rotating gear disk 5 is driven to rotate, ensuring the effect of the driving mechanism 6.

[0046] Secondly, a certain gap is left between the upper plane of the locking ring 7 and the rotating gear disk 5, that is, the upper plane of the rotating gear disk 5 is located outside the locking ring 7, which is convenient for the meshing of the driving gear 62 with the sawtooth on the outer sidewall of the rotating gear disk 5.

[0047] Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
