[0002] Industrial equipment for producing polyethylene film is widely used in packaging, agriculture, construction, medical treatment and other fields, and its core process is to make polyethylene resin into film through steps of heating and melting, extrusion molding, blowing or stretching, cooling and shaping, and winding, etc. The existing polyethylene film production equipment, as shown in the application number CN202411916223.2, "High-puncture-resistance polyethylene geomembrane and its production device and production process", uses a ring die (for blown film method, to produce cylindrical film), in this process, the user needs to pull the just-extruded film into a ring shape to form a cylindrical film bubble, and in order to ensure stable molding, a higher support is generally needed to convey and transfer upward, this process is also relatively cumbersome, and generally needs multiple people to complete or the user to continuously hold the end of the film bubble to extend upward, which has the disadvantage of extremely inconvenient operation. SUMMARY

[0003] The present application aims to solve the above technical problems, and provides an intelligent polyethylene film production equipment.

[0004] In order to achieve the above-mentioned purpose, the present application specifically adopts the following technical solutions: The present application provides an intelligent polyethylene film production equipment, which comprises a machine body, a frame body and a film blowing device on the machine body, the frame body has a frame cavity, and the outlet end of the film blowing device leads out a film bubble; The frame body is provided with a guide device on the outside; The guide device comprises a lifting device, an extender fixed to the output end of the lifting device, a clamping jaw fixed to the output end of the extender, and a clamping plate fixed to the output end of the clamping jaw, and further comprises a button fixed to the outside of the frame body; The clamping jaw has two opposite output ends that are close to each other and far away from each other, and the outside of each output end is fixed with a clamping plate, when the end of the film bubble is placed between the two groups of clamping plates, the clamping jaw operates to make the two groups of clamping plates close to clamp the end of the film bubble; the lifting device operates to pull the film bubble to stably convey in the frame cavity; and the extender retracts to operate to drive the clamping jaw to separate from the top of the film bubble.

[0005] As a preferred technical solution of the present application, the clamping plate comprises a plate body fixed to the output end of the clamping jaw, a plate cavity provided on the plate body, a pressure sensor fixed in the plate cavity, a paste plate partially placed in the plate cavity, and an elastic member fixed in the plate cavity; The sensing end of the pressure sensor is fixed with the paste plate, and the outside of the paste plate is fixed with the elastic member.

[0006] As a preferred embodiment of the present invention, the elastic element is provided in multiple sets and is evenly distributed within the plate cavity.

[0007] As a preferred technical solution of the present invention, the lifting device includes a housing fixed to the outside of the frame, a threaded rod rotatably connected inside the housing, a forward and reverse motor disposed outside the housing, a support plate fixed outside the housing, a slider threaded through the threaded rod, and a guide bar slidably connected to the outside of the slider. The top end of the threaded rod protrudes outside the housing and is fixed to the output end of the forward and reverse motor. The housing is also provided with a strip-shaped opening, and part of the slider protrudes from the strip-shaped opening and is fixed to the telescopic device.

[0008] As a preferred embodiment of the present invention, the guiding device further includes; A distance sensor is fixed to the outside of the lifting device and is located above the telescopic joint for monitoring its height and distance. A drive winding device is fixed between the telescopic device and the gripper.

[0010] The beneficial effects of this invention are as follows: The lifting device is pre-operated to drive the telescopic mechanism, grippers, and clamping plates to an appropriate height. At this point, the end of the membrane bubble is placed between the two sets of clamping plates, and the operation button is pressed to clamp the end of the membrane bubble. The lifting device then operates, causing the telescopic mechanism and grippers to move upward steadily, ensuring a good shape and high convenience for the membrane bubble. Meanwhile, the user quickly moves the device upward on the frame. Once the end of the membrane bubble has moved to the appropriate position, another button is used to stop the operation. At the same time, the grippers release their clamping action, and the telescopic mechanism drives the grippers and clamping plates to retract. This does not obstruct the subsequent transport of the membrane bubble, greatly simplifying the operation process. Attached Figure Description

Detailed Implementation Example 1:

[0013] like Figure 1 As shown in the figure, this embodiment proposes an intelligent polyethylene film production equipment, including a machine body 1 and a frame 2 and a blown film device 3 on it. The frame 2 has a frame cavity between them. The outlet end of the blown film device 3 leads out a film bubble. The frame 2 is equipped with a climbing and walking frame (not shown in the figure). The user pulls the annularly extruded film into a cylindrical shape at the outlet end of the blown film device 3, and squeezes the top end in the center to form a closed film bubble end. The user then holds the film bubble upward and pulls it upward. During this process, the end of the film bubble is cooled to provide minimal or no adhesive force. It also includes a PLC controller that connects to an external power source to power and switch on / off the electrical components; A guide device 4 is fixedly installed on the outside of the frame 2, and the guide device 4 is set at the rear end of the frame 2. The guiding device 4 includes a lifting device a, a telescopic device b fixed to the output end of the lifting device a, a gripper c fixed to the output end of the telescopic device b, and a clamping plate d fixed to the output end of the gripper c; it also includes a button fixed to the outside of the frame 2, the gripper c is an automatic gripper (such as an electric gripper, model: EFG-8), the button is located near the gripper c and the button is electrically connected to the components that start the operation of the lifting device a, the telescopic device b and the gripper c, and the button is electrically connected to the PLC controller; and the button is provided in at least two parts, one part is located near the blown film device 3 and the other part is located on the outside of the frame 2 near where the gripper c stops moving upward; The gripper c has two output ends that are close to each other and far apart, and clamping plates d are fixed on its outer side respectively. When the end of the membrane bubble is placed between the two sets of clamping plates d, the gripper c rotates so that the two sets of clamping plates d move closer to clamp the end of the membrane bubble; the lifting device a rotates to pull the membrane bubble in the frame cavity to be steadily conveyed upward; the telescopic device b retracts and rotates to drive the gripper c to disengage from above the membrane bubble. The lifting device a is pre-operated to drive the telescopic device b, gripper c, and clamping plate d to adjust to a suitable height. At this time, the end of the membrane bubble is placed between the two sets of clamping plates d, and the operation button is pressed to clamp the end of the membrane bubble. The lifting device a then drives the telescopic device b and gripper c to move upward steadily, ensuring a good shape effect and high convenience for the membrane bubble. At the same time, the user quickly moves upward on the frame 2. After the end of the membrane bubble moves to a suitable position, the operation is stopped by another button. At the same time, the gripper c releases its clamp, and the telescopic device b drives the gripper c and clamping plate d to retract. This will not obstruct the subsequent transmission of the membrane bubble, greatly simplifying the operation process. The specific structure of the clamp d is shown below: The clamping plate d includes a plate body d1 fixed to the output end of the gripper c, a plate cavity d2 disposed on the plate body d1, a pressure sensor d3 fixed in the plate cavity d2, a patch plate d4 partially placed in the plate cavity d2, and an elastic element d5 fixed in the plate cavity d2. The sensing end of the pressure sensor d3 is fixed to the plate d4, and the outer side of the plate d4 is fixed to the elastic element d5; the model of the pressure sensor d3 is: FSG15N1A or E8F2-R10C; the elastic element d5 can be a cylindrical helical spring and its two opposite elastic ends are respectively fixed inside the plate cavity d2 and the plate d4. like Figure 1 As shown, the membrane bubble end is located between the adhesive plate d4 of the two sets of clamping plates d. When the clamping claw c drives the two plates d1 to move closer to each other, the adhesive plate d4 continuously presses against the membrane bubble end until the pressure sensor d3 reaches the preset sensing pressure, that is, the membrane bubble end has been pressed and can be moved upward stably; the elastic element d5 can provide support for the adhesive plate d4 to improve the stability of the adhesive plate d4 in the use position.

[0014] Among them, the elastic element d5 is provided in multiple sets and is evenly distributed in the plate cavity d2; multiple sets of elastic elements d5 are evenly and reasonably arranged to provide better support stability.

[0015] The specific structure of the lifting device a is shown below: The lifting device a includes a housing a1 fixed to the outside of the frame 2, a threaded rod a2 rotatably connected inside the housing a1, a forward and reverse motor a3 located outside the housing a1, a support plate a4 fixed outside the housing a1, a slider a5 threaded through the threaded rod a2, and a guide bar a6 slidably connected to the outside of the slider a5. The top end of the threaded rod a2 protrudes outside the housing a1 and is fixed to the output end of the forward and reverse motor a3. The housing a1 is also provided with a strip-shaped opening, and part of the slider a5 protrudes from the strip-shaped opening and is fixed to the telescopic device b. When the lifting device a is in use, the forward and reverse motor a3 runs, which drives the threaded rod a2 to rotate in the forward or reverse direction. The threaded rod a2 is threaded through the slider a5. Under the sliding limit action of the slider a5 on the guide bar a6, the slider a5 moves up and down, thereby driving the telescopic device b to move synchronously, and thus realizing the adjustment of the position of the gripper c and the clamping plate d. The forward and reverse motor a3 is an existing type of motor [such as a DC motor that switches between forward and reverse rotation by changing the direction of the input current (i.e., changing the positive and negative terminals of the power supply).] Example 2:

[0016] like Figure 1 As shown, the difference between this embodiment and Embodiment 1 is that the guiding device 4 further includes; The distance sensor e is fixed to the outside of the lifting device a (specifically, such as...) Figure 1 , 2 As shown, distance sensor e is fixed on the upper outer side of housing a1. Distance sensor e is located above telescopic device b for monitoring its height and distance. The model of distance sensor e is: Keyence IL-300 or SICK OD5000 laser rangefinder (non-contact). The drive winding device f is fixed between the telescopic device b and the gripper c. The output end of the drive winding device f is fixed to the gripper c to drive the gripper c and the clamping plate d to rotate. When the telescopic device b moves to a suitable height and is detected by the distance sensor e, the drive winding device f will operate and rotate the membrane bubble. It can pull the membrane at a fixed position before the user reaches the pick-up point. The membrane bubble that has reached the maximum height has cooled down (i.e., it is no longer sticky), which can also ensure quick removal. It has strong functionality.

[0017] The specific structure of the drive winding device is shown below: The drive winding device f includes a rotary joint f1, a first gear f2 fixed to one end of the rotary joint f1, a second gear f3 meshing with the outer side of the first gear f2, and a rotator f4 whose output end is fixed to the outer side of the second gear f3. The outer side of the rotator f4 is fixed to the output end of the telescopic device b, and the two ends of the rotary joint f1 are fixed to the output end of the telescopic device b and the outer side of the gripper c, respectively. The rotary joint f1 provides power for the opening and closing of the gripper c, which is rotated by the slip ring. The rotator f4 is a motor (which can be a servo motor) to provide rotational force. The rotation of the rotator f4 drives the second gear f3 to rotate, which in turn drives the meshing first gear f2 to rotate, and then drives the rotating end of the gripper c connected to the rotary joint f1 to rotate. When reused, the flatness of the gripper c can be adjusted by the controller.

[0018] The control method of this invention is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the art. Furthermore, since this invention is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
