Description

Technical Field

[0001] This utility model relates to the field of film blow molding technology, and in particular to a side guard plate device that can automatically identify and adjust movement. Background Technology

[0002] Film blowing is a major method for producing plastic films. It involves extruding molten plastic to form a tubular preform, which is then inflated with compressed air, cooled by an air ring, flattened by clamping rollers, and finally wound into a double-layer film. This method includes flat extrusion top blowing, flat extrusion bottom blowing, and flat extrusion flat blowing.

[0003] A blow molding machine is a plastic processing machine. After liquid plastic is sprayed out, the machine uses airflow to blow the plastic body into a mold cavity of a specific shape, thus creating a product. This type of machine is called a blow molding machine. Alternatively, plastic is melted and extruded in a screw extruder in a measured quantity, then formed through a die, cooled by airflow from a fan ring, and then pulled at a certain speed by a traction machine before being wound into a roll by a winding machine.

[0004] In existing technology, a downblown membrane is formed into a bubble through a mold, and then extruded into a sheet-like membrane material through a herringbone clamp. The membrane bubble is clamped into a double-layer membrane material by the herringbone clamp and conveyed to the rear device. Currently, there are no devices on both sides of the herringbone clamp, which causes unstable air pressure inside the membrane bubble at the bottom, resulting in wrinkles appearing in the membrane bubble during the extrusion process.

[0005] Therefore, based on years of experience and practice in related industries, the inventor proposes a side guard plate device that can automatically identify and adjust movement to overcome the shortcomings of the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a side guard plate device with automatic movement adjustment for main identification, which overcomes the problem in the prior art where unstable air pressure inside the membrane bubble causes wrinkles during the extrusion process. This invention can autonomously control the degree of membrane bubble extrusion through the movement adjustment unit and the identification detection unit. By increasing the air pressure inside the membrane through extrusion, it can autonomously identify and adjust the distance between the guard plate and the membrane bubble in real time according to the degree of extrusion, so that the flattening uniformity of the membrane bubble is better and the membrane will not cause wrinkles or other product quality problems due to extrusion.

[0007] The purpose of this utility model is achieved as follows: a side guard plate device with autonomous identification and automatic movement adjustment includes guard plates disposed on both sides of a herringbone clamp that can squeeze the membrane bubble from the side. A movement adjustment part that can drive the guard plate to move is abutted on the guard plate.

The identification detection part is electrically connected to the movement adjustment part, and the identification detection part controls the movement adjustment part to adjust the distance between the guard plate and the membrane bubble in real time.

[0010] In a preferred embodiment of the present invention, the self-identifying and automatically moving adjustment side guard plate device further includes a support structure, on which a moving adjustment part connection structure and an identification and detection part connection structure are provided.

[0037] like Figures 1 to 4 As shown, this utility model provides a side guard plate device with autonomous identification and automatic movement adjustment, including guard plates 1 disposed on both sides of a herringbone clamp 4 and capable of squeezing the bubble 5 from the side. A movement adjustment part 2 is abutting the guard plate 1 and capable of driving the guard plate 1 to move. At least one end of the guard plate 1 along the height direction of the herringbone clamp 4 is provided with an identification detection part 3 for automatically identifying the degree of squeezing of the bubble 5 and the guard plate 1. The identification detection part 3 is electrically connected to the movement adjustment part 2, and the identification detection part 3 controls the movement adjustment part 2 to adjust the distance between the guard plate 1 and the bubble 5 in real time.

[0038] During operation, the center of the membrane bubble will tilt slightly during rotation. The self-identifying and self-adjusting side guard plate device keeps the membrane bubble smooth before entering the clamping roller, preventing wrinkles, center folds, or other damage to the membrane surface.

[0039] This invention uses the identification and detection unit 3 to detect the depth of deformation of the membrane bubble under the pressure of the protective plate. During the rotation of the herringbone clamp, the membrane bubble will be squeezed differently depending on its position. The identification and detection unit 3 can autonomously control the movement adjustment unit 2 to drive and adjust the distance between the protective plate 1 and the membrane bubble 5, so that the flattening of the membrane bubble is more uniform and it is less likely to produce product quality problems such as wrinkles.

[0040] This invention can autonomously control the degree of membrane bubble compression through the movable adjustment unit 2 and the identification and detection unit 3. By compressing, the air pressure inside the membrane is increased. The distance between the guard plate 1 and the membrane bubble 5 is adjusted in real time according to the degree of compression, so that the flattening of the membrane bubble is more uniform and the membrane will not cause product quality problems such as wrinkles due to compression.

[0041] Furthermore, such as Figure 1 , Figure 2 As shown, the movable adjustment unit 2 includes a lead screw 21 and a drive unit. The drive unit includes a drive motor 22, and a drive nut is connected to the drive motor. The lead screw 21 passes through the drive nut, and one end of the lead screw 21 is hinged to the guard plate 1. The drive motor 22 drives the drive nut to rotate so as to drive the lead screw 21 to move.

[0042] Furthermore, the identification and detection unit 3 includes an ultrasonic sensor, which is electrically connected to the drive motor 22. The ultrasonic sensor measures the distance between the protective plate 1 and the membrane bubble 5 to automatically identify the degree of compression of the membrane bubble 5. The ultrasonic sensor controls the operation of the drive motor 22 according to the degree of compression, thereby adjusting the forward or backward movement of the lead screw 21.

[0043] Furthermore, such as Figure 1 , Figure 3 As shown, the self-identifying and automatically adjusting side guard plate device also includes a support structure 6, on which a movement adjustment part connecting structure 61 and an identification and detection part connecting structure 62 are provided.

[0044] Furthermore, such as Figure 1 , Figure 3 As shown, the movable adjustment unit connection structure 61 includes a connecting block body 611 that is slidably connected to the support structure 6, and a drive motor 22 is connected to the connecting block body 611.

[0045] Furthermore, such as Figure 1 , Figure 3 As shown, the connecting block body 611 is connected to a connecting hole that can be fitted onto the support structure 6. The side wall of the connecting hole is provided with a push rod structure 612 that can press against the support structure 6. Tightening the push rod structure 612 inwards can fix the connecting block body 611 onto the support structure 6, and loosening the push rod structure 612 outwards can allow the connecting block body 611 to move along the support structure 6.

[0046] Furthermore, such as Figure 1 , Figure 3 As shown, the identification and detection unit connection structure 62 includes a connector 621 fixed on the support structure, and an ultrasonic sensor is connected to the connector 621.

[0047] Furthermore, such as Figure 1 , Figure 3 , Figure 4 As shown, the support structure 6 is provided with an external connecting bracket 63, and the support structure 6 is connected and fixed to the side of the herringbone clamp 4 through the external connecting bracket 63. In a specific embodiment, the external connecting bracket 63 is arranged in a U-shape, and the external connecting bracket 63 can be snapped and fixed to the crossbeam 41 (prior art) on the side of the herringbone clamp 4.

[0048] Furthermore, such as Figure 1 As shown, a hinge seat 11 is provided on the guard plate 1, and one end of the lead screw 21 is hinged to the hinge seat 11. The hinge seat can adopt a movable joint structure to meet the possible tilting requirements of the guard plate 1.

[0049] Example 1:

[0050] In this embodiment, as Figure 1 As shown, a recognition and detection unit 3 is provided at both ends of the guard plate 1 along the height direction of the herringbone clamp 4, and a moving adjustment unit 2 is provided at each of the recognition and detection units 3. The recognition and detection units 3 and the moving adjustment units 2 are electrically connected in a one-to-one correspondence.

[0051] Specifically, such as Figure 4 As shown, the self-identifying and automatically moving adjustment side guard plate device of this utility model is set at the bottom of the herringbone clamp 4. The guard plate 1 is used to squeeze the membrane bubble 5 from the side to ensure sufficient air pressure at the bottom of the membrane bubble 5.

[0052] This utility model uses an ultrasonic sensor to measure the distance between the protective plate 1 and the membrane bubble 5. The upper and lower ends of the protective plate 1 are equipped with a moving adjustment part 2, namely a drive motor 22 and a lead screw 21, to control the forward and backward movement of the protective plate 1.

[0053] The support structure 6 has ultrasonic sensors at both its upper and lower ends. Each ultrasonic sensor is electrically connected to the drive motor 22 at the upper and lower ends, respectively, to control the rotation of its corresponding drive motor 22, thereby controlling the forward and backward movement of the lead screw 21. This invention is installed on both sides of the herringbone clamp 4. Ultrasonic sensors are used to automatically identify the degree of membrane bubble compression, and this compression degree is used to control the drive motor and lead screw to maintain the forward movement of the guard plate (the forward and backward movement of the lead screw 21 and the guard plate 1).

[0054] The upper and lower parts of the guard plate 1 are connected to the lead screw 21 via a hinge seat 11 (movable joint), and the lead screw 21 is then connected to the drive motor 22. The hinge seat 11 (movable joint) allows the upper and lower parts of the guard plate 1 to tilt freely without restriction. The lead screw 21 can move forward or backward under the drive of the drive motor 22. The added ultrasonic sensor is used to sense the degree of compression between the membrane bubble 5 and the guard plate 1 (the depth of deformation of the membrane bubble 5 by the guard plate 1), thereby adjusting the forward or backward movement of the lead screw. During the rotation of the membrane bubble, the center of the membrane bubble will tilt slightly. Through autonomous recognition and adjustment, the membrane bubble is kept smooth before entering the clamping roller, preventing wrinkles, center folds, and other damage to the membrane surface.

[0055] An ultrasonic sensor (ultrasonic rangefinder) is connected to each end of the support structure 6. The ultrasonic sensor is a miniature component used to sense the membrane surface of the bubble 5. A fixed distance between the membrane surface and the ultrasonic sensor is set first. When the ultrasonic sensor cannot sense the membrane surface, the drive motor 22 is controlled to rotate the drive screw 21 to push the guard plate 1 inward and squeeze the bubble 5. When the bubble 5 is squeezed out and detected by the ultrasonic sensor, the drive motor 22 stops rotating and the screw 21 stops moving forward. Similarly, when the bubble 5 is squeezed out too much, the drive motor 22 is controlled to rotate the drive screw 21 to move the guard plate 1 outward and backward.

[0056] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model.
