Description

Technical Field

[0001] The utility model relates to the field of film rolling equipment, in particular to an automatic film unloading device for an air-expansion shaft of an air bubble film. Background Art

[0002] In the production and processing of plastic bubble wrap, plastic film, and other rolls, air shafts are widely used to support and rewind the material. Conventional air shaft unloading systems are complex, inefficient, and lack automated control, resulting in unstable and unsafe unloading processes. Existing technologies often require manual intervention, which is labor-intensive and prone to damage to the roll.

[0003] As for the current automatic winding device for strapping tape, especially for bubble film with a larger single layer thickness, the degree of automation is relatively low, and the feeding and unloading of the roll film still requires a lot of manual operation. In order to solve this problem, an automated device for automatic unloading of the roll film is needed. Summary of the Invention

[0007] Preferably, a sensor for sensing contact between the supporting surface and the film roll is provided on the base, and the sensor is connected to a control device, which is connected to a lifting power source. When the sensor senses contact between the supporting surface and the film roll, it sends a contact signal to the control device, which controls the lifting power source to stop the action. By extending the track along the axial direction of the inflation shaft and cooperating with the sliding power source on the mobile mounting frame, the mobile mounting frame can automatically slide back and forth on the track, thereby improving the convenience and efficiency of operation. The cooperation between the sensor, the control device and the lifting power source realizes the precise detection and control of the contact between the film roll and ensures the stability and safety of the lifting process of the unloading bracket.

[0010] Preferably, a block is provided on the side of the mobile mounting frame or unloading bracket. The block has a retaining slot for the swing arm to enter. An arm within the retaining slot holds the swing arm upright, limiting its forward swing. The block and retaining slot design prevent excessive swinging of the swing arm, ensuring smooth unloading.

[0011] Preferably, the swing power source is mounted on the mobile mounting frame. The swing power source is a cylinder. The output shaft of the cylinder is hinged to the swing arm, and the bottom of the swing arm is hinged to the mobile mounting frame. The swing power source uses the cylinder to drive the swing arm to swing, realizing automatic swinging of the unloading member, reducing manual operation and improving the degree of automation.

[0012] Preferably, a roller is provided at the bottom of the mobile mounting frame, the output end of the sliding power source is connected to a driving wheel, a passive wheel is further installed on the mounting shaft of the roller, and the driving wheel and the passive wheel are connected by a synchronous belt or chain.

[0013] Preferably, the support surface of the bottom bracket is horizontal or V-shaped with an opening facing upward. The V-shaped support surface design enables the device to adapt to rolls of different shapes and sizes, increasing its stability and versatility in supporting the rolls.

The track 1 is extended along the axial direction of the air expansion shaft; the movable mounting frame 2 is connected to a sliding power source 21, and the sliding power source 21 drives the movable mounting frame 2 to slide back and forth on the track 1; the discharge bracket 3 is installed on the movable mounting frame 2, and the discharge bracket 3 includes a base support 31. The top surface of the base support 31 has a supporting surface for supporting the roll film, and the discharge bracket 3 is connected to a lifting power source 32 for driving the base support 31 to rise and fall; the roll discharge member 4 is arranged on a swing arm 41, and the swing arm 41 is connected to a swing power source 411. A slot 42 cooperating with the air expansion shaft is provided on the side of the roll discharge member 4 facing the air expansion shaft, and the side of the roll discharge member 4 located on the side of the discharge bracket 3 is used to contact the roll film and push the roll film out relative to the air expansion shaft.

[0024] A sensor for sensing the contact between the supporting surface and the roll film is provided on the base 31. The sensor is connected to a control device, which is connected to the lifting power source 32. When the sensor senses the contact between the supporting surface and the roll film, it sends a contact signal to the control device, which controls the lifting power source 32 to stop moving.

[0025] like Figure 3-4 As shown, guide slides 22 are fixedly installed on the left and right sides or the front and back sides of the mobile mounting frame 2, and a slide 23 is slidably provided on the guide slide 22. The mobile mounting frame 2 includes a support leg 24, and several support legs 24 are arranged obliquely. One end of the support leg 24 is hinged to the slide 23, and the other end is hinged to the unloading bracket 3. The lifting power source 32 is connected to at least one slide 23 and drives the slide 23 to slide on the guide slide 22, driving the support leg 24 to swing and causing the base 31 to rise or fall.

[0026] The lifting power source 32 is a motor 321, a screw 332 and a nut 333. The nut 333 is fixedly mounted on the slide 23. The screw 332 and the nut 333 are threadedly matched. The screw 332 is connected to the motor 321. The motor 321 drives the screw 332 to rotate and pushes the slide 23 to slide along the guide slide 22.

[0027] A clamping block 25 is provided on the side of the mobile mounting frame 2 or the unloading bracket 3. The clamping block 25 is provided with a limiting groove 251 for the swing arm 41 to enter. The inner groove arm of the limiting groove 251 keeps the swing arm 41 upright and limits the swing arm 41 from continuing to swing forward.

[0028] The swing power source 411 is installed on the mobile mounting frame 2 . The swing power source 411 is a cylinder. The output shaft of the cylinder is hinged to the swing arm 41 . The bottom of the swing arm 41 is hinged to the mobile mounting frame 2 .

[0029] A roller 26 is provided at the bottom of the mobile mounting frame 2, the output end of the sliding power source 21 is connected to a driving wheel 27, a driven wheel 28 is further installed on the mounting shaft of the roller 26, and the driving wheel 27 and the driven wheel 28 are connected by a synchronous belt or chain.

[0030] The supporting surface of the bottom bracket 31 is horizontal or V-shaped with an opening facing upward.

[0031] Working Principle: After the film roll is completed, the unloading roll needs to be transferred. First, the unloading bracket 3 moves on the mobile mounting frame 2 to a position that supports the film roll. Before supporting the film roll, the base support 31 is equipped with a sensor for sensing contact between the supporting surface and the film roll. This can be a probe that contacts the film roll, an infrared detector, or a weight detector. When the sensor senses that the film roll is on the supporting surface, the motor 321 of the lifting power source 32 stops, stabilizing the unloading bracket 3 at this height. At this time, the power source 411 drives the swing arm 41 to swing, and the slot 42 of the unloading unit 4 is stuck on the side of the air shaft. The top surface of the base support 31 of the unloading bracket 3 has a structure that supports the film roll. The unloading bracket 3 then moves in the opposite direction on the mobile mounting frame 2, keeping the air shaft in the slot 42 of the unloading unit 4. The unloading unit 4 pushes the film roll and pulls it off the air shaft. The base support 31 maintains support for the film roll throughout the entire process, facilitating the transfer or collection of the film roll in the next step.
