Description
Technical Field
The invention relates to the technical field of film stretching treatment, in particular to a dynamic stabilizing mechanism of a chain clamp and a synchronous stretching device.
Background
With the development of film stretching technology, film stretching apparatuses have appeared. The film is stretched in certain times in longitudinal and transverse directions by a film stretching device in a proper temperature range (in high-elasticity state) above the glass transition temperature and below the melting point, so that molecular chains or crystal faces are oriented in a direction parallel to the plane of the film and orderly arranged, then the film is subjected to heat setting in a tensioning state, the oriented macromolecular structure is fixed, and finally the film is prepared by cooling and subsequent treatment. Typically, the film stretching device includes two guide rails and a chain clip assembly correspondingly movably disposed on the guide rails. The opposite sides of the film are respectively pulled by the chain clamp assemblies on the two guide rails, and the chain clamp assemblies stretch and expand the film longitudinally and transversely under the guidance of the guide rails. The change of the distance between the two corresponding outer guide rails along the film channel determines the stretching rate of the film in the transverse direction, and the change of the distance between the inner guide rail and the outer guide rail of one rail determines the stretching rate of the film in the longitudinal direction.
Wherein the guide rail comprises a plurality of track plates which can be used for adjusting the position of the guide rail, and the length of the guide rail is consistent with the length of an oven unit area where the guide rail is positioned (typically, for example, 3000 mm). The flexible rail is fixedly connected with the rail plates connected in series at intervals through fastening bolts, and the guide rail at the bending connection part of the end part of the rail plates is in a local suspension state and is bent into an arc shape. Each chain clip component is supported by the top surface of the flexible rail and guided by the two side surfaces of the flexible rail, and the two sides of the traction film run.
Conventionally, in order to ensure that the two sides of the film are pulled along the line and simultaneously realize longitudinal and transverse biaxial stretching, the chain clamp assembly is subjected to various extreme forces, and a derailment trend or phenomenon possibly caused by jumping and upwarping easily occurs.

Referring to fig. 1 and 2, fig. 1 is a schematic structural view of a dynamic stabilization mechanism of a chain clip according to an embodiment of the present invention, and fig. 2 is another view of the structure shown in fig. 1. The invention provides a dynamic stabilization mechanism of a chain clamp, which comprises an annular guide rail 10 and a chain clamp assembly 20. The annular guide rail 10 comprises a first guide rail 11 and a second guide rail 12 which are arranged at intervals inside and outside. The side of the first rail 11 facing away from the second rail 12 is provided with a first auxiliary rail 13. The chain clip assembly 20 is movably disposed on the endless rail 10, and the chain clip assembly 20 includes at least one first moving assembly 21 movably disposed on the first rail 11, and at least one second moving assembly 22 movably disposed on the second rail 12. The first moving assembly 21 comprises a first base 211 movably arranged on the first guide rail 11, a first limiting piece 212 is arranged on the side surface of the first base 211, which is opposite to the second guide rail 12, the first limiting piece 212 can move along the first auxiliary rail 13, and the first auxiliary rail 13 can limit the first limiting piece 212 to be separated from the first guide rail 11 upwards.
According to the dynamic stabilizing mechanism of the chain clamp, when the chain clamp assembly 20 moves along the annular guide rail 10, the first moving assembly 21 moves along the first guide rail 11, the second moving assembly 22 moves along the second guide rail 12, and the first limiting piece 212 can move along the first auxiliary rail 13, namely, the first limiting piece 212 cannot interfere with the movement of the first moving assembly 21 along the first guide rail 11, and in addition, the first auxiliary rail 13 can limit the first limiting piece 212 to be separated from the first guide rail 11 upwards, so that the first limiting piece 212 is relatively stable in the moving process, and the jumping-off and upturned trend in the moving process of the first moving assembly 21 can be avoided.
In one embodiment, the second rail 12 is provided with a second secondary rail 14 on the side facing away from the first rail 11. The second moving assembly 22 includes a second seat 221 movably disposed on the second rail 12, and a second limiting member 222 is disposed on a side of the second seat 221 facing away from the first rail 11. The second limiting member 222 can move along the second auxiliary rail 14, and the second auxiliary rail 14 can limit the second limiting member 222 to be separated upward from the second guide rail 12. Similarly, the second auxiliary rail 14 can limit the second limiting member 222 from being separated from the second guide rail 12, so that the second limiting member 222 is relatively stable in the moving process, and the tendency of jumping off and tilting up in the moving process of the second moving assembly 22 can be avoided.
It should be noted that, the first limiting member 212 can move along the first auxiliary rail 13, and the specific structural manner in which the first auxiliary rail 13 can limit the first limiting member 212 to be separated upward from the first guide rail 11 includes: the first limiting piece 212 is in interference fit with the bottom surface of the first auxiliary rail 13; for another example, the first auxiliary rail 13 is provided with a sliding groove, and the first limiting member 212 is slidably disposed in the sliding groove, so that the sliding groove not only plays a guiding role, but also plays a good limiting role on the first limiting member 212, and the first limiting member 212 is prevented from being separated from the first guide rail 11 upwards.
Similarly, the second limiting member 222 can move along the second auxiliary rail 14, and the second auxiliary rail 14 can limit the second limiting member 222 from being separated upward from the second guide rail 12, for example, the specific structural manners include: the second limiting piece 222 is in interference fit with the bottom surface of the second auxiliary rail 14; for another example, the second auxiliary rail 14 is provided with a sliding groove, and the second limiting member 222 is slidably disposed in the sliding groove, so that the sliding groove not only plays a guiding role and facilitates movement of the second limiting member 222, but also plays a good limiting role on the second limiting member 222, and prevents the second limiting member 222 from being separated from the second guide rail 12 upwards.
The first limiting member 212 and the bottom surface of the first auxiliary rail 13 are mutually abutted to realize horizontal limiting, and the second limiting member 222 and the bottom surface of the second auxiliary rail 14 are mutually abutted to realize horizontal limiting, so that the chain clamp assembly 20 is continuously limited in a horizontal deviation space along the line and is not influenced by the transverse adjustment of the track of the first guide rail 11 and the track of the second guide rail 12.
The "first sub rail 13" may be "a portion of the first rail 11", that is, "the first sub rail 13" is integrally formed with "other portions of the first rail 11"; it is also possible that a separate component, i.e. "first sub rail 13", which is separable from "other parts of first rail 11", can be manufactured separately and then combined in one piece with "other parts of first rail 11".
It should be noted that, the "second auxiliary rail 14" may be "a portion of the second guide rail 12", that is, "the second auxiliary rail 14" is integrally formed with "other portion of the second guide rail 12"; or may be a separate component from the other portions of the second rail 12, i.e., the second secondary rail 14 may be manufactured separately and then integrated with the other portions of the second rail 12.
When the first rail 11 is an inner rail, the second rail 12 is an outer rail provided at intervals on the outer periphery of the first rail 11; conversely, when the first rail 11 is the outer rail, the second rail 12 is the inner rail.
Referring to fig. 3 to 5, fig. 3 is a schematic structural diagram of a dynamic stabilization mechanism of a chain clip according to an embodiment of the invention; fig. 4 is an enlarged schematic view showing the structure of fig. 3 at a; fig. 5 shows another view of the structure of fig. 4. In one embodiment, the first limiting member 212 is a roller, a slider, or a ball; the second limiting member 222 is a roller, a slider or a ball. Thus, when the first limiting member 212 and the second limiting member 222 are configured as rollers, the first limiting member 212 is in rolling contact with the first auxiliary rail 13 through the wheel surface of the rollers, so that the movement effect is smooth and stable, and the tendency of jumping and tilting is not easy to occur. Similarly, the second limiting part 222 is in rolling contact with the second auxiliary rail 14 through the wheel surface of the roller, so that the movement effect is smooth and stable, and the tendency of jumping and upwarping is not easy to occur.
Referring to fig. 3 and 6, it should be noted that, by adjusting the distance between one section (e.g. the stretch section) of the circular guide rail 10 and another circular guide rail 10, the transverse stretch ratio of the circular guide rail 10 at that position can be adjusted accordingly. Furthermore, adjusting the distance between a certain section of the first rail 11 and the second rail 12 enables the longitudinal stretch of the endless rail 10 at that location to be adjusted accordingly. In the process of adjusting the distance between one section of the annular guide rail 10 and another annular guide rail 10 and adjusting the distance between one section of the first guide rail 11 and one section of the second guide rail 12, the arc-shaped change of the first guide rail 11 and the arc-shaped change of the second guide rail 12 are caused. However, when the first rail 11 is provided with the first sub rail 13 and the second rail 12 is provided with the second sub rail 14, local rigidity of the first rail 11 and the second rail 12 is increased, and a phenomenon of arc distortion is easily caused.
Referring to fig. 3 to 5, in one embodiment, the first guide rail 11 includes at least two first body sections 111 disposed in sequence, and a first arc-shaped connecting section 112 correspondingly connected between two adjacent first body sections 111. The first auxiliary rail 13 includes at least two first main rail sections 131 disposed in sequence, and a first arc-shaped rail section 132 correspondingly connected between the adjacent two first main rail sections 131. The first main track section 131 is correspondingly connected with the first main body section 111, the first arc track section 132 is correspondingly connected with the first arc connecting section 112, the first arc track section 132 is provided with a plurality of first connecting positions which are connected with the first arc connecting section 112 and are arranged at intervals along the longitudinal direction, one of the first connecting positions at the middle part of the first arc track section 132 is a fixed connecting position, and the other first connecting positions are movable connecting positions which can move along the longitudinal direction.
Referring to fig. 3 to 5, in one embodiment, the second guide rail 12 includes at least two second body sections 121 disposed in sequence, and a second arc-shaped connecting section 122 correspondingly connected between two adjacent second body sections 121. The second secondary track 14 comprises at least two second main track segments arranged in sequence, and a second arcuate track segment correspondingly connected between two adjacent second main track segments. The second main track section is correspondingly connected with the second main body section 121, the second arc track section is correspondingly connected with the second arc connecting section 122, the second arc track section is provided with a plurality of second connecting positions which are connected with the second arc connecting section 122 and are arranged at intervals along the longitudinal direction, one of the second connecting positions at the middle part of the second arc track section is a fixed connecting position, and the other second connecting positions are movable connecting positions which can move along the longitudinal direction.
As such, it has been found through the study of the inventor that in the course of changing the position by driving the first rail 11 and the second rail 12, generally, the first arc-shaped connection section 112, the first arc-shaped track section 132, the second arc-shaped track section, and the second arc-shaped connection section 122 undergo arc-shaped change after being stressed, and the first body section 111, the first body track section, the second body section 121, and the second body track section do not undergo arc-shaped change. Therefore, one of the first connection positions located at the middle part of the first arc-shaped track section 132 is set as a fixed connection position, specifically, for example, the first connection position located at the right middle position of the first arc-shaped track section 132 is set as a fixed connection position, and the fixed connection position is in a fastening connection state, so that the connection position cannot move along the longitudinal direction; the rest first connecting positions are movable connecting positions which can move along the longitudinal direction, namely the rest first connecting positions can move along the longitudinal direction, so that the phenomenon of radian distortion caused in the stressed moving process can be avoided. Likewise, one of the second connection positions located at the middle part of the second arc-shaped track section is set as a fixed connection position, specifically, for example, the second connection position located at the right middle position of the second arc-shaped track section is set as a fixed connection position, and the fixed connection position is in a fastening connection state, so that the second connection position cannot move along the longitudinal direction; the rest second connecting positions are movable connecting positions which can move along the longitudinal direction, namely the rest second connecting positions can move along the longitudinal direction, so that the phenomenon of radian distortion caused in the stressed moving process can be avoided.
