Description

Technical Field

[0001] The invention relates to the technical field of special film preparation, in particular to a heating system for a horizontal stretching machine. Background Art

[0002] In the field of film production, the horizontal stretching machine plays an important background technical role in heating and horizontal stretching of films. The molecular chains of many film materials, such as polyolefins, are relatively fixed at room temperature, and it is difficult to achieve ideal orientation and performance improvement by direct horizontal stretching. By heating the film with a horizontal stretching machine, the film is placed in a suitable softening temperature range, and the activity of the molecular chains is enhanced. In the subsequent horizontal stretching process, the molecular chains are arranged in order along the stretching direction, which greatly improves the tensile strength, barrier properties and other properties of the film, meeting the needs of multiple industries such as packaging and electronics for high-quality films.

[0003] The patent application with application number CN202222723928.5 discloses a heating system for a horizontal stretching machine, including a frame, the inner cavity of the frame is divided into an upper chamber and a lower chamber by a special film laid therein, two guide rails are arranged on both sides of the lower chamber along the length direction, and a first electric heating tube and a second electric heating tube are arranged between the two guide rails, a plurality of first electric heating tubes are provided and are arranged at intervals along the length direction of the lower chamber, and the length direction of the first electric heating tube is perpendicular to the length direction of the guide rail, a plurality of second electric heating tubes are provided and are distributed on both sides of the length direction of the first electric heating tube, and the length direction of the second electric heating tube is parallel to the length direction of the guide rail; a third electric heating tube is provided in the upper chamber, a plurality of third electric heating tubes are provided and are arranged at intervals along the length direction of the lower chamber, and the length direction of the third electric heating tube is perpendicular to the length direction of the guide rail.

[0004] In summary, when performing transverse stretching operations on special films of different thicknesses and stretching them to different widths, the transverse stretching machine needs to be adjusted. During the stretching process of the special film, if there is a difference in the clamping force at both ends, the transverse thickness of the special film will be uneven, which may cause excessive local force on the film due to uneven clamp pressure.

[0005] Therefore, we proposed a heating system for a horizontal stretching machine. Summary of the invention

[0016] Compared with the prior art, the present invention provides a heating system for a horizontal stretching machine, which has the following beneficial effects:

[0017] 1. The present invention sets up a heating system for a transverse stretching machine.

[0019] 3. The present invention sets an auxiliary mechanism and uses an auxiliary motor to drive the support frames on both sides of the film to rotate toward both ends, so as to achieve the purpose of stretching the film to different widths according to the deflection angle of the support frames.

[0020] 4. The present invention sets a fixed plate and an inclined plate. The fixed plate applies a thrust to the clamping block, prompting the clamping block to move toward the conveyor belt. During this process, the first roller drives the special films of different thicknesses to move toward the auxiliary mechanism. When the clamping block is separated from the fixed plate, the second elastic component pushes the clamping block to move toward one side of the special film and clamps and fixes its two ends. When the inclined plate generates a thrust on the clamping block to make it move toward the conveyor belt again, the clamping and fixing state of the two ends of the special film is released and is no longer restricted by the clamping block, thereby facilitating the separation of the special film from the conveyor belt after the horizontal pulling operation.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0032] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Example 1: See Figure 1-Figure 3 The present invention provides a technical solution: a heating system for a horizontal stretching machine, comprising a supporting mechanism 1, the supporting mechanism 1 comprising a first fixed frame 101, the outer wall of the first fixed frame 101 is fixedly connected with a supporting foot 102, the inner wall of the first fixed frame 101 is fixedly connected with an infrared heating lamp 104, the inner wall of the first fixed frame 101 is provided with a sliding groove 105, the outer wall of the first fixed frame 101 is fixedly connected with a first connecting frame 106, the outer wall of the first fixed frame 101 away from the first connecting frame 106 is fixedly connected with an auxiliary motor 103, the inner wall of the first fixed frame 101 close to the auxiliary motor 103 is fixedly connected with a second connecting frame 111, the outer surface of the second connecting frame 111 is provided with a through hole 112, and the end of the second connecting frame 111 away from the first fixed frame 101 is provided with an adjustment mechanism 2, and also includes:

[0034] The auxiliary mechanism 3 includes a support frame 301 fixedly connected to the output end of the auxiliary motor 103, the outer wall of the end of the support frame 301 away from the auxiliary motor 103 is rotatably connected to the second roller 302 through a rotating shaft, the outer surface of the support frame 301 is rotatably connected to the conveyor belt 303 through a rotating shaft, and a clamping block 304 is arranged inside the conveyor belt 303. When special films of different thicknesses are to be pulled horizontally to different widths, the output end of the auxiliary motor 103 drives the support frame 301 to rotate, and the second roller 302 rolls on the inner wall of the sliding groove 105, so as to improve the stability of the support frame 301 during rotation. After the two ends of the special film are clamped by the clamping block 304, multiple groups of infrared heating lamps 104 heat it evenly, and then the conveyor belt 303 stretches and conveys the special film horizontally.

[0035] A dual-axis motor 107 is fixedly connected to the inner wall of the first connecting frame 106, and a rotating frame 108 is fixedly connected to the output end of the dual-axis motor 107. An end of the rotating frame 108 away from the dual-axis motor 107 is rotatably connected to an auxiliary roller 109 via a rotating shaft. A first elastic component 110 is fixedly connected to the inner wall of the auxiliary roller 109. When the special film operation is completed, the dual-axis motor 107 operates to drive the rotating frame 108 to rotate toward the special film, and the auxiliary roller 109 rotates accordingly and contacts the special film, and relies on its own rotation and friction to squeeze and push the special film.

[0036] Example 2: Please refer to Figure 4-Figure 5 On the basis of the first embodiment, the present invention provides a technical solution: the adjustment mechanism 2 includes a hydraulic rod 201 fixedly connected to the second connecting frame 111, the output end of the hydraulic rod 201 is fixedly connected to the first sliding block 202, the inner wall of the first sliding block 202 is rotatably connected to the rotating rod 203 through a rotating shaft, the end of the rotating rod 203 away from the first sliding block 202 is rotatably connected to the second sliding block 204 through a rotating shaft, the second sliding block 204 is slidably connected to the inner wall of the through hole 112, and the second sliding block 204 is away from the rotating rod 2 The outer wall of one end of 03 is fixedly connected to the second fixed frame 205, and the through hole 112 is used to limit the sliding distance of the second sliding block 204. When performing horizontal pulling operations on special films of different thicknesses, the hydraulic rod 201 applies a thrust to the first sliding block 202, prompting the first sliding block 202 to move away from the second connecting frame 111. During the movement of the first sliding block 202, the force is transmitted to the second sliding block 204 with the help of the rotating rod 203, causing the second sliding block 204 to move in the direction of the special film.

[0037] The inner wall of the second fixed frame 205 is rotatably connected to the first driving roller 206 via a rotating shaft, and the inner wall of one end of the second fixed frame 205 away from the first driving roller 206 is rotatably connected to the second driving roller 207 via a rotating shaft. The first driving roller 206 and the second driving roller 207 are used for conveying special films. The second driving roller 207 is shorter than the first driving roller 206. Since the side of the second fixed frame 205 close to the second driving roller 207 is narrower than the first driving roller 206, when the auxiliary mechanism 3 clamps and fixes the film, this width difference makes it easier for the auxiliary mechanism 3 to clamp the special film on both sides of the film. The outer wall of one end of the second fixed frame 205 close to the second driving roller 207 is fixedly connected to a fixing plate 208. The outer wall of one side of the second fixed frame 205 close to the fixed plate 208 is rotatably connected to the first roller 209 through a rotating shaft. The first roller 209 is rollingly connected to the outer surface of the special film. The fixed plate 208 is used to push the clamping block 304 toward the side of the conveyor belt 303. When the conveying task of special films of different thicknesses is carried out, the first driving roller 206 and the second driving roller 207 on the upper and lower sides of the special film are started, and the two cooperate with each other to clamp the special film, and then start the conveying action. At the same time, the fixed plate 208 generates a thrust on the clamping block 304, causing the clamping block 304 to move toward the conveyor belt 303. During this process, the first roller 209 causes the special films of different thicknesses to move toward the auxiliary mechanism 3.

[0038] Example 3: Please refer to Figure 6-Figure 8 On the basis of the first and second embodiments, the present invention provides a technical solution: a second elastic component 306 is fixedly connected to the outer wall of the clamping block 304 on one side close to the conveyor belt 303, and the second elastic component 306 is fixedly connected to the conveyor belt 303 at one end away from the clamping block 304, and a flexible gasket 305 is fixedly connected to the outer wall of the clamping block 304 on one side away from the second elastic component 306. The second elastic component 306 generates a force to push the clamping block 304 to move toward the two ends of the special film. During the movement, the flexible gasket 305 fixedly connected to the bottom outer wall of the clamping block 304 contacts and applies pressure to the two ends of the special film, thereby achieving clamping and fixing of the two ends of the special film.

[0039] A connecting rod 307 is fixedly connected to the outer wall of one side of the support frame 301 close to the second roller 302, and a tilting plate 308 is fixedly connected to the connecting rod 307 away from the support frame 301. When the conveyor belt 303 is running and conveys the clamping block 304 toward the tilting plate 308, as the clamping block 304 gradually approaches the tilting plate 308, the tilting plate 308 will generate a thrust on the clamping block 304, causing the clamping block 304 to move in the direction of the conveyor belt 303. Due to the change in the position of the clamping block 304, the clamping state of the two ends of the special film is released, and the special film is no longer restricted by the clamping block 304, which makes it easy to remove the special film from the conveyor belt 303 after the horizontal pulling operation, thereby realizing the separation of the special film from the conveyor belt 303.
