Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The utility model provides a material receiving shaft for plastic film production, which comprises a material receiving part 3 and mounting parts 1 which are symmetrically arranged at two ends of the material receiving part as shown in figures 1 and 2, wherein the material receiving part 3 comprises an inner cylinder body 304 and an outer cylinder body sleeved on the inner cylinder body 304, the outer cylinder body is composed of a plurality of arc-shaped plates 303 with the same structure, and a supporting mechanism for pushing the arc-shaped plates 303 to move outwards is arranged in the inner cylinder body 304.

Among the above-mentioned technical scheme, accessible supporting mechanism promotes the arc outwards to remove, and then increases the diameter of receiving the material portion. During the use, when the arc did not outwards move, a receipts feed cylinder internal diameter for receiving the material was greater than the diameter of receiving the material portion, consequently received the feed cylinder and can easily cup joint to receiving on the material portion, and then promoted the arc outwards and remove through supporting mechanism to only compress tightly the inner wall at the material portion, consequently, the material portion is received to the receipts feed cylinder can only cup joint, and stable completion is received the material operation. After the material receiving is completed, the arc-shaped plate resets, the diameter of the material receiving part is reduced, and therefore the material receiving cylinder can be easily taken down from the material receiving shaft. Simple structure and convenient operation.

Specifically, as shown in fig. 2 to 5, the supporting mechanism includes two push rods 302 sleeved in the inner cylinder 304 in a symmetrical structure and a plurality of supports 307, one end of each support 307 is hinged to a side wall of the push rod 302, and the other end of each support 307 is hinged to an inner wall of the arc-shaped plate 303.

It can be understood that when the push rod is pushed, the angle formed by the support and the push rod is gradually increased, and the distance between the top of the support and the push rod is increased, so that the arc-shaped plate is pushed to move outwards. The operation is very convenient.

Specifically, the supporting member 307 includes a fixing plate 307b, a supporting column 307c and a hinge tube 307e, one side of the fixing plate 307b is in an arc structure and is fixed on the inner wall of the arc-shaped plate 303, the other end of the supporting column 307c is hinged to the other side of the fixing plate 307b through a hinge 307a, one end of the supporting column 307c is fixedly provided with the hinge tube 307e, the outer wall of the push rod 302 is provided with a plurality of hinge seats 308, the hinge tube 307e is rotatably connected to the hinge seats 308, and the inner cylinder 304 is provided with a guide hole 305 for the supporting column 307c to pass through corresponding to each hinge seat 308.

When the push rod is pushed, the angle formed by the support column 307c and the push rod is gradually increased, and the distance between the push rod and the top of the support column 307c is increased, so that the arc-shaped plate is pushed to move outwards. The operation is very convenient.

It can be understood that more and more materials of rolling on the arc, the weight that the arc bore also increases thereupon, therefore support piece's quantity is more, and the support column supports the arc stability better.

Further, a limiting rod 306 is arranged in the guide hole 305, a sliding hole 307d for the limiting rod 306 to pass through is arranged in the supporting column 307c, and the sliding hole 307d is in a strip structure along the supporting column 307 c.

Through the setting of guiding hole and gag lever post to it is better to promote the outside stability of removal of arc.

Further, the section of the push rod 302 is a regular polygon, and one end of the push rod 302 extends to the outside of the material receiving portion 3 and is connected to the mounting portion 1. The mounting part 1 comprises a mounting shaft 102, an inserting hole 101 matched with the push rod 302 is formed in the axis position of the mounting shaft 102, and the length of the push rod 302 exposed outside the material receiving part 3 is larger than the depth of the inserting hole 101.

Through the arrangement of the push rod 302 with the section not in the shape of a regular polygon and the matched inserting hole, the stability is better after the inserting is finished.

It can be understood that the length of the push rod 302 exposed outside the material receiving portion 3 is greater than the depth of the insertion hole 101. Therefore, the bottom side of the insertion hole 101 will be pressed against the end of the push rod 302, thereby completing the pushing effect.

Furthermore, the radial outer wall of the mounting shaft 102 is provided with a plurality of locking holes 103 communicated to the inside of the inserting hole 101, and the outer wall of the push rod 302 is provided with locking columns 301 matched with the locking holes 103.

Because the arc rolling material is more and more, and the gravity that receives is also more and more big, consequently, through the setting in locking post and locking hole, avoid the arc reaction force to the push rod on for the push rod outwards removes. In addition, set up a plurality of locking holes, the locking hole of different positions can promote the different distance of push rod, and the outward distance that moves of arc is also different simultaneously, consequently is suitable for the receipts feed cylinder in different apertures, and application scope is wider.

Further, a plurality of rotary bearings 2 are fixed on the radial outer wall of the mounting shaft 102.

Further, the outer wall of the arc-shaped plate 303 is a rough surface. The rough surface is contacted with the inner wall of the material receiving cylinder, and the friction force is increased, so that the installation is firmer, and the material receiving is more stable.

It should be noted that, this application not only is applicable to the rolling of film, and the product that arbitrary needs the rolling all is in the scope of protection of this application.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments, including the components, without departing from the principles and spirit of the utility model, and still fall within the scope of the utility model.
