Description

Technical Field

[0001] This utility model relates to the field of membrane production technology, and in particular to a blown film traction roller correction mechanism. Background Technology

[0002] In existing blown film production lines, traction rollers often experience lateral shifts during film operation due to uneven material tension, equipment vibration, or feeding deviations. If not corrected in time, this can easily lead to quality problems such as edge tearing, uneven winding, or uneven thickness distribution.

[0003] Traditional correction mechanisms mostly rely on manual adjustment, which is inefficient and slow to respond. In addition, the automatic correction function of some equipment is prone to jamming and unstable operation during use, and lacks an effective real-time early warning mechanism, resulting in untimely correction. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as "low efficiency of manual adjustment, slow response, and the automatic correction function of some equipment being prone to jamming of the transmission mechanism and unstable operation during use, and lacking an effective real-time early warning mechanism, resulting in untimely correction." Therefore, this invention proposes a blown film traction roller correction mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A blown film traction roller correction mechanism includes: a mounting base, a feeding roller is provided on one side of the mounting base, a traction roller is provided on the other side of the mounting base, a connecting plate is provided at the upper end of the mounting base, a correction roller is provided on the connecting plate, and a correction component is provided on the correction roller;

[0007] The correction component includes an adjustment groove formed on the mounting base, a slider slidably disposed in the adjustment groove, and a transmission arm disposed at the bottom of the slider.

[0008] As a preferred embodiment of the blown film traction roller correction mechanism of this utility model, the bottom of the slider is elliptical and its outer wall is slidably connected to the adjustment groove, the mounting base is provided with a mounting groove, and a starting component is provided in the mounting groove.

[0009] In a preferred embodiment of the blown film traction roller correction mechanism of this utility model, the starting component includes a cylinder fixedly disposed in the mounting base, a toothed plate being provided at the output end of the cylinder, a rotating disk being rotatably disposed on the mounting base, and a gear being fixedly disposed at the bottom of the rotating disk.

[0010] In a preferred embodiment of the blown film traction roller correction mechanism of this utility model, the gear meshes with the toothed plate, and the transmission arm is fixedly connected to the rotating disk.

[0011] As a preferred embodiment of the blown film traction roller correction mechanism of this utility model, the mounting base is provided with a warning component for observing whether the material is deviated, and a receiver for use with the warning component is provided on the upper outer side of the mounting base.

[0012] In a preferred embodiment of the blown film traction roller correction mechanism of this utility model, the warning component includes a mounting plate fixedly disposed on the upper end of the mounting base, a connecting block disposed on the mounting plate, an elastic reset member disposed inside the connecting block, a locking block disposed at one end of the elastic reset member, and an infrared transmitter connected to the upper end of the connecting block.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The cylinder-driven toothed plate meshes with gears to drive the rotating disk and transmission arm, precisely adjusting the sliding position of the slider within the adjustment groove. This enables rapid and stable adjustment of the alignment roller, effectively correcting material deviation. The elliptical slider design significantly improves guidance and stability during sliding, reducing the risk of jamming. Combined with a real-time monitoring system consisting of an infrared transmitter and receiver, automated early warning and dynamic correction are achieved. The overall structure offers rapid response and precise control, significantly reducing tearing and uneven thickness caused by film deviation during traction, thus improving production continuity and product yield.

Detailed Implementation

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "set up," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Reference Figure 1 , Figure 3 , Figure 4 A blown film traction roller correction mechanism includes a mounting base 101, a feeding roller 102 on one side of the mounting base 101, a traction roller 103 on the other side of the mounting base 101, a connecting plate 201 at the upper end of the mounting base 101, a mounting groove 205 inside the mounting base 101, a starting component 203 in the mounting groove 205, and a correction roller 202 on the connecting plate 201. Considering the need to correct the deviation of the material, a correction component 204 is provided on the correction roller 202. The correction component 204 includes an adjustment groove 2043 on the mounting base 101, a slider 2042 slidably disposed in the adjustment groove 2043, the bottom of the slider 2042 being elliptical and its outer wall being slidably connected to the adjustment groove 2043, and a transmission arm 2041 at the bottom of the slider 2042.

[0024] The mounting base 101 has a mounting groove 205, and a starting component 203 is provided in the mounting groove 205. The starting component 203 includes a cylinder 2031 fixedly installed in the mounting base 101. A toothed plate 2032 is provided at the output end of the cylinder 2031. A rotating disk 2034 is rotatably installed on the mounting base 101. A gear 2033 is fixedly installed at the bottom of the rotating disk 2034. The gear 2033 meshes with the toothed plate 2032. A transmission arm 2041 is fixedly connected to the rotating disk 2034.

[0025] Referring to the figure, considering the need to monitor the position of the material in real time to prevent displacement, the mounting base 101 needs to be equipped with a warning component 206 for observing whether the material is displaced. The upper part of the mounting base 101 is equipped with a receiver that is used in conjunction with the warning component 206. The warning component 206 includes a mounting plate 2061 fixedly mounted on the upper part of the mounting base 101. A connecting block 2062 is provided on the mounting plate 2061. An elastic reset component 2063 is provided inside the connecting block 2062. A locking block 2064 is provided at one end of the elastic reset component 2063. An infrared transmitter 2065 is connected to the upper end of the connecting block 2062.

[0026] When the material shifts laterally during traction, the infrared transmitter 2065 and receiver mounted on the mounting plate 2061 monitor the material's position in real time. If the material shifts and blocks the infrared light, the signal between the infrared transmitter 2065 and receiver is interrupted, triggering an alarm to alert the operator. The cylinder 2031 in the starting component 203 is activated, and its output pushes the toothed plate 2032 to move. The toothed plate 2032 meshes with the gear 2033, driving the rotating disk 2034 to rotate. The rotating disk 2034 drives the slider 2042 to slide along the adjusting groove 2043 via the transmission arm 2041. The elliptical design at the bottom of the slider 2042 ensures sliding stability. Finally, the position of the correction roller 202 is adjusted by the transmission arm 2041 to correct the alignment of the traction roller 103 with the material. Once the shift is corrected, the signal between the infrared transmitter 2065 and receiver is restored, and the system returns to normal operation.

[0027] It is worth noting that the entire device is controlled by a controller. Since the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the protection scope of this utility model. In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
