Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a continuous kneading machine, and more particularly to a continuous kneading machine having a rotating shaft around which a stirring member is provided in a cylindrical casing.

[Prior Art] If the conventional kneaders of this type are further classified, there are a single-screw screw type, and a double-screw type in which a large number of paddles are combined on the two shafts and fixed around the axis. One of the inner rotating shafts protrudes out of the casing and engages with the drive shaft to receive a rotational force, and the other is rotatably supported by a side plate of the casing or outside the casing in a sealed state.

For example, FIG. 6 shows an example of this type, in which a rotary shaft 3a having a stirring member 2a provided in a cylindrical casing 1a is supported at one end by a drive unit 4a and at the other end by a shaft support 72a. Between the both ends of the casing and the extending portion of the rotating shaft, the sealing portion 71a prevents leakage of the fluid material inside. By the way, since the basic function is to move the fluid while kneading the fluid in the sealed casing, avoid the problem of degrading the kneading action by viscous material adhering to or infiltrating the voids of the casing inner wall and stirring member There are some suggestions for improvement of this type because it cannot be passed.

That is, in Japanese Utility Model Laid-Open No. 62-170134 / FIG. 7, the lower surface of the casing (case) 1b is a base 10
1 is provided with a rolling shaft 102 that moves the upper surface of the base away from the upper surface of the rotating body 3b.
It can be exposed from b.

Further, in FIG. 8 of Japanese Utility Model Laid-Open No. 1-167325, since blade shafts 104 and 105 are provided in opposite states on both sides of a trough 1c for rotatably accommodating the blade 103, the blade shafts are provided between the blade shafts. Is detachably connected.

In addition, Japanese Utility Model Publication No. 64-40506 and Japanese Utility Model Publication No. 64-40506
Japanese Patent No. 28938 discloses the improvement of the purpose for solving the same problem. In addition, the actual exploitation Sho 62-957
In the prior art of Japanese Patent Publication No. 30, the basic structure of the kneading machine is opened at the upper side, and the kneading material is charged from the open portion of the can body having a U-shaped cross section, and when the kneading is completed, the can body itself is opened. The material is discharged downward by pivoting to reverse the open portion downward. Since the rotating shaft is supported at both ends independently of the can body, the shaft is sealed with a sealing material so that the material does not leak from the shaft portion penetrating the can body. After all, the purpose of this device is to easily remove and clean this seal part,
In order to easily replace the worn seal material, the support material into which the seal material is inserted is divided into two parts, both members are integrally connected with the rotary shaft sandwiched, and then the whole is attached to the outer surface of the can body. The main purpose is to lock the fixed ring to the rotating shaft.

[Problems to be Solved by the Invention] In the prior art shown in FIG. 7, although the rotating body can be pulled out from the casing and exposed, the cleaning purpose can be achieved.
Since the mutual relationship between the casing and the rotating body does not change at all times, if the properties of the material to be treated inside the casing change, it is necessary to immediately follow this and replace it with an optimum rotating body, which requires a troublesome work. .

In this respect, in the prior art shown in FIG. 8, the blade can be easily replaced and the inside of the trough can be cleaned, but the bearing portion and the sealing portion are integrally assembled as they are. It must be said that the problems common to the relevant model, such as leakage, are still insufficient.
Furthermore, in the conventional technique disclosed in Japanese Utility Model Publication No. 62-95730,
It is clear that the purpose is to maintain cleanliness in the vicinity of the seal part where the rotating shaft projects from the can body, and it does not bring any improvement to the main body of other devices, that is, the kneading space in the casing. is there. In the first place, since it is a basic configuration in which the upper part is largely opened and the can itself tilts, it is unlikely that a large burden has been imposed on the cleaning of the kneading space, and the gist of this conventional technology is also It cannot be read that there is a sense of purpose.

In order to solve the above-mentioned problems, the present invention makes it easy to dismantle and clean all members including the casing and the rotating body, as well as the bearing and the sealing, and to promptly request a change in the kneading function itself. The purpose of the present invention is to provide a new continuous kneader that can handle the above.

[Means for Solving the Problems] In the continuous kneading machine according to the present invention, a rotating shaft 3 around which a stirring member 2 is provided in a split casing 1 having a sealed cylindrical shape, and one end of a drive unit 4 outside the casing is provided. The drive shaft 5 is detachably engaged with the drive shaft 5 in the horizontal direction, and the other end thereof forms an extending portion 32 extending to the outside of the casing. The extending portion 32 is a sealing member connected to the casing 1. The aforementioned problem is solved by inserting the sleeve 6 rotatably fitted in the stopper 71 and the shaft support 72 so as to be engageable and disengageable.

[Operation] Since the kneading machine of the present invention has the above structure, the casing 1 is disconnected from the sealing portion 71 and the shaft support portion 72, and the sleeve 6
If the engagement between the rotary shaft and the extending portion 32 of the rotary shaft is released, the sealing portion 71,
The shaft supporting portion 72 and the sleeve 6 are integrally pulled out horizontally from the extending portion. After pulling out the sleeve and the like, the extended portion of the shaft protruding while being exposed from the end portion of the casing is disengaged from the drive shaft 5 at one end of the casing and pulled out horizontally from the casing. Remove all with the stirring member attached. Since the hollow casing is divided into two parts, remove the upper half and clean the inside. If the stirring member is cleaned and the combination of the members is changed due to the change of the kneading material, both can be easily worked out of the machine. If you prepare in advance the necessary number of sets mounted on the rotating shaft with a type arrangement for kneading A material, b type arrangement for kneading B material, and arrangement of stirring members for each kneading material, Instantly respond to material changes and replace the entire rotating shaft.

[Example] A rotating shaft 3 around which a stirring member 2 is provided in a cylindrical casing 1.
Is detachably engaged with the drive shaft 5 rotated by the drive unit 4 at one end. As an embodiment of the stirring member 2, the figure shows a state in which various combinations of convex lens-shaped or triangular paddle-shaped paddles are mounted around the rotation axis. To engage the drive shaft and the rotary shaft, as shown in FIGS. 2A and 2B, a convex portion and a concave portion which are fitted to each other are provided between the tip 31 of the rotary shaft 3 and the tip 51 of the drive shaft 5. It is preferable that it can be inserted freely.

The other of the rotating shafts is an extending portion 32 that extends outside from the side plate 11 of the casing 1, and is fitted in the sleeve 6 that rotates together with the rotating shaft over its entire length. The sleeve 6 is axially supported so as to prevent the fluid material being kneaded in the casing from leaking to the outside. Specifically, as shown in the figure, the sleeve 6 is covered by the gland packing 71 in the bearing box 7. It is enclosed and receives a sealing action, and is supported by a bearing 72.

In order to assemble and lock these members, set bolt 6
1, nut 73, oil seals 74, 75, etc. are used.

Now, when the stop bolt 61 is removed in FIG. 1, the engagement between the rotary shaft 3 and the sleeve 6 is released. Next, the body flange 12 of the casing and the side plate 11 are unscrewed, and the side plate 11, the sealing portion 71, the shaft support portion 72, and the sleeve 6 fitted in the former two are completely taken together on the right side of the drawing. Horizontally,
Only the extending portion 32 of the rotating shaft 3 remains exposed while protruding from the body flange of the casing. Since the casing 1 is divided into upper and lower parts, the upper half is removed and opened.
When the rotary shaft 3 is moved to the right in the casing by the length of the tip 51 with which the drive shaft engages, the engagement of both shafts is released,
With the stirring member 2 and the rotating shaft 3 assembled into a set, the stirring member 2 and the rotating shaft 3 are lifted upward and removed from the casing.

FIG. 3 shows a rotating part which is removed and exposed, and a large number of paddles are fitted on the shaft, and all are closely fitted and tightly tightened by the nut 21 to break the mutual relationship combined to fulfill a special condition. I have maintained without.

In this state, the inside of the casing and the outer surface of the paddle can be cleaned.

Also, insert another rotary shaft with a paddle that is combined under the same conditions into the casing instead, and insert the assembly that combines all the outer peripheral members such as the sleeve, the sealing part, and the shaft support part on the outer periphery of the rotary shaft extension part. The paddle part can be instantly replaced by fitting it in and fastening the end face to the end face of the casing. The rotating shaft with paddle after removal can be prepared for the next replacement after being well-maintained on a worktable with good workability.

In addition, when the materials to be supplied change frequently and the processing conditions are required to change accordingly, the desired number of rotary shafts equipped with a combination of stirring members (such as paddles) that satisfy each condition beforehand can be used. This request can be easily fulfilled by preparing and replacing the members in the state shown in FIG. 3 as appropriate.

FIGS. 4A and 4B are front sectional views showing another embodiment, which adopts a structure in which the same sealing and pivotal support functions as those of the rotary shaft in FIG. 1 are added to the drive shaft side in either the right or left direction. Can also be released horizontally.

Next, a preferred embodiment for preventing the seizure of the rotary shaft 3 and the sleeve 6 will be described. As shown in FIGS. It is fitted in the groove 33 with a slight gap, and a lock nut 63 is screwed into the lock bolt 61 to prevent it from loosening.

The action peculiar to this embodiment is that it can absorb the expansion and expansion of the rotary shaft caused by heat that is found in melt-kneading and the like, and the rotary shaft and the sleeve can smoothly rotate together.

[Effects of the Invention] As described above, the invention of the present application makes it easy to clean the residue and the like in the sealed casing, and if the rotary shaft is replaced with a spare part, the equipment is instantly completed and the kneading conditions are changed. When it is necessary, it is possible to change to a combination of members that is optimal for this condition. That is, the effect of maximizing the efficiency and maintenance of the device and greatly expanding the versatility of the device is achieved.
