Description

Reel storage device for multi-layer co-extrusion film blowing machine

Technical Field

The utility model belongs to the field of mechanical equipment, relates to the field of blow molding machines, and specifically relates to a winding and storing device of a multi-layer film blow molding machine.

Background Art

When using a multi-layer co-extrusion blow molding machine to produce film, the film needs to be rolled up and stored. The winding equipment currently used has a certain thickness of the film to be rolled up. In order to ensure that the film is not disturbed during rolling, the support of the winding roller has a certain height, and the winding roller has a certain weight after winding the film. Therefore, it is inconvenient to unload it. Traditionally, it is necessary to use lifting equipment to remove the winding roller from the winding equipment, which is troublesome and laborious. In addition, on the winding equipment currently used, when the film is rolled up along the winding roller with the help of the roller shaft, the roller shaft structure is single and does not provide guidance and limitation for the film, which easily causes problems such as film rolling wrinkles and irregular rolling.

Utility Model Content

The utility model is to solve the technical problems that the film is difficult to unload and wrinkles easily when rolled, and provides a winding storage device for a multi-layer co-extrusion film blowing machine. The retaining ring on the outer wall of the guide roller guides and limits the film to make the winding regular, and adjusts the deflection angle of the connecting frame so that the winding roller can roll up the film and unload it. The operation is simple, labor-saving and flexible.

The technical solution adopted by the utility model is: to provide a winding and storage device of a multi-layer co-extrusion film blowing machine, comprising a frame and a connecting frame rotatably arranged on the frame at a fixed angle, the free end of the connecting frame being arranged obliquely downward, and a winding roller and an intercepting frame being movably arranged on the connecting frame; a guide roller is rotatably installed on a side of the frame away from the connecting frame, and retaining rings are slidably connected to both ends of the side wall of the guide roller; a driving roller is rotatably installed in the frame, the driving roller is located between the guide roller and the winding roller, and the driving roller is in contact with and fits the winding roller; a driving device is fixedly installed on the outer wall of the frame, and the output end of the driving device is coaxially assembled with the driving roller.

When the film passes around the guide roller and the driving roller in the frame in turn, the position of the retaining ring on the guide roller is adjusted to make it contact with the film to prevent the film from swinging on the guide roller and make the film rolled up smoothly. The connecting end of the connecting frame and the frame is deflected upward, so that the winding roller moves along the connecting frame under gravity and keeps in contact with the driving roller. When the driving roller rotates, the winding roller is driven to rotate by friction transmission to roll up the film. After the winding is completed, the free end of the connecting frame is tilted downward to facilitate the winding roller to slide down from the connecting frame for unloading and transfer. During the downward movement of the winding roller, the interception frame on the connecting frame intercepts the winding roller to limit the downward movement rate of the winding roller and improve its safety.

To further optimize the technical solution, the front end of the connecting frame is rotatably hinged to the frame, and the connecting frame is connected to the frame by means of a hydraulic rod, and both ends of the hydraulic rod are rotatably hinged to the frame and the connecting frame respectively.

The front end of the connecting frame is hinged to the frame, so that it has the freedom to rotate along the frame, and the connection of the hydraulic rod to the frame and the connecting frame limits the rotation angle of the connecting frame, avoiding large-scale deflection of the connecting frame. The deflection control is precise and labor-saving, and the hydraulic rod supports the connecting frame to ensure the safety and reliability of its use.

To further optimize the technical solution, slide rails are fixedly installed on both sides of the top wall of the connecting frame, the shapes of the slide rails correspond to those of the connecting frame, pulleys are provided on the slide rails, and the pulleys are rotatably installed with the winding roller and the intercepting frame respectively.

The winding roller and the interception frame are connected to the slide rail through a pulley, so that they move smoothly and stably. When the winding roller is winding the film, the consistency of movement of the winding roller and the interception frame is guaranteed, so that the winding roller can wind the film smoothly and the interception frame can intercept the winding roller reliably.

To further optimize the technical solution, through holes are provided on both sides of the bottom of the intercepting frame, the through holes are slidably connected to the connecting frame, and the pulleys are installed in the through holes; the intercepting frame is slidably connected to the connecting frame by means of a damping sliding assembly.

The intercepting frame is slidably connected to the connecting frame through a through hole, and the pulley is installed in the through hole to make it slide smoothly. The intercepting frame is connected to the connecting frame with the help of a damping sliding component to limit the sliding rate of the intercepting frame, thereby limiting the sliding rate of the winding roller and making the winding roller move downward stably and safely.

To further optimize the technical solution, the damping sliding assembly includes a slide groove arranged on the outer wall of the connecting frame and a bolt threadedly connected to the intercepting frame, and the bolt abuts against the slide groove.

The abutment between the bolt and the slide groove provides damping for the sliding of the intercepting frame along the connecting frame, limits the downward movement rate of the intercepting frame and the winding roller along the connecting frame, and after the bolt slides to the end of the slide groove, the intercepting frame stops the movement of the winding roller and supports the winding roller, which is close to the supporting surface, making it easy to unload and transfer it, and is labor-saving and flexible to use.

To further optimize the technical solution, the side wall of the guide roller is provided with an annular connection pad, the retaining ring is slidably connected to the connection pad, and the retaining ring is magnetically matched with the connection pad by means of a magnetic attraction member.

The connection pad increases the contact friction with the retaining ring, so that the position of the retaining ring on the guide roller remains stable, while the magnetic attraction piece improves the firmness of the connection and positioning between the retaining ring and the guide roller, ensuring the stability of the film guide.

To further optimize the technical solution, the magnetic attraction component includes a metal sleeve sleeved with the inner ring wall of the connecting pad and a magnet magnetically connected to the metal sleeve, the metal sleeve is sleeved with the guide roller, and the magnet is fixedly connected to the retaining ring.

The connection pad shields the metal sleeve, does not damage the contact guide of the film, and does not interfere with the magnetic connection of the magnet, so it is flexible and reliable to use.

To further optimize the technical solution, the inner ring wall of the retaining ring is provided with an assembly groove, and the assembly groove is fixedly sleeved with the magnet.

The magnetic attraction is assembled on the inner wall of the retaining ring, so that the outer wall of the retaining ring remains flat and does not interfere with the guidance of the film.

To further optimize the technical solution, the driving device includes a coaxially assembled driving motor and a reduction gear box, the reduction gear box is fixedly mounted on the outer wall of the frame, and the output end of the reduction gear box is coaxially assembled with the driving shaft.

The reduction gearbox reduces the speed of the drive motor and increases the torque on the drive shaft, making the drive shaft rotate stably and smoothly, ensuring the stability and reliability of film winding.

The beneficial effects of the utility model are:

1. When winding the film, the front end of the connecting frame connected to the frame is supported by the hydraulic rod and kept tilted upward, so that the winding roller is subjected to gravity and slides downward along the connecting frame, and always keeps in contact with the driving roller to ensure the continuity and stability of the winding. After the winding is completed, the connecting frame deflects to a horizontal state along the bracket, and the winding roller is moved to the downward tilted free end to save effort, and the winding roller moves downward along the free end of the connecting frame, which is convenient for unloading and transferring the winding roller, and is flexible to use;

2. When the winding roller moves downward along the free end of the connecting frame, the intercepting frame abuts against the winding roller, and the bolt abuts against the slide groove, providing friction damping for the intercepting frame, limiting the downward movement rate of the intercepting frame along the connecting frame, that is, limiting the downward movement rate of the winding roller, avoiding the winding roller from stalling and causing loss of control, and improving the safety and reliability of downward unloading;

3. After the film is guided by the guide roller and rolled up by the winding roller, the slidingly connected retaining ring on the guide roller prevents the film from swinging on the guide roller, ensuring the smoothness of the rolling. The connecting pad on the guide roller increases the friction with the retaining ring, and the magnet on the retaining ring is magnetically attracted to the metal sleeve in the connecting pad, which improves the firmness of the retaining ring on the guide roller and the guiding and restraining effect on the film.

4. The matching setting of the pulley and the slide rail makes the winding roller and the interception frame move smoothly along the connecting frame, and the pulley ensures the consistency of the movement of the winding roller and the two ends of the interception frame along the connecting frame, so that the film is rolled flat and the interception frame intercepts the winding roller reliably.

DETAILED DESCRIPTION

The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

Please refer to Figures 1 and 2. The winding and storage device of the multi-layer co-extrusion film blowing machine includes a frame 1 and a connecting frame 2 that is rotatably arranged on the frame 1 at a fixed angle. The front end of the connecting frame 2 is rotatably hinged with the frame 1 so that it has the freedom to rotate along the frame 1. The connecting frame 2 is connected to the frame 1 by means of a hydraulic rod 9. The two ends of the hydraulic rod 9 are rotatably hinged with the frame 1 and the connecting frame 2 respectively. The hydraulic rod 9 supports the connecting frame 2 and limits its rotation angle. The free end of the connecting frame 2 is tilted downward, so that the use of the connecting frame 2 is diverse. A winding roller 3 and an intercepting frame 4 are movably arranged on the connecting frame 2. A guide roller 5 and a driving roller 7 are arranged in the frame 1. The guide roller 5 is located on the side away from the connecting frame 2, and the driving roller 7 is located between the guide roller 5 and the winding roller 3. When the film is wound, the hydraulic rod 9 supports the connecting frame 2 so that its front end is tilted upward, so that the winding roller 3 is subjected to gravity and moves along the front end of the connecting frame 2 and keeps in contact with the driving roller 7.

Please refer to Figures 1, 6, and 7. When the film is rolled up, the film is first made to pass around the guide roller 5. The two sides of the side wall of the guide roller 5 are interactively connected to the retaining ring 6. The retaining ring 6 adjusts its interval according to the film specifications to limit the film from moving randomly and guide it to make the rolling regular. The side wall of the guide roller 5 is sleeved with an annular connecting pad 12. The retaining ring 6 is slidably connected with the connecting pad 12 to increase the contact friction, so that the position of the retaining ring 6 remains stable and the guiding stability is improved. The retaining ring 6 can be magnetically matched with the connecting pad 12 by means of a magnetic suction member, so that the retaining ring 6 is firmly held in the position of the guide roller 5. The magnetic suction member includes a metal sleeve 13 sleeved with the inner ring wall of the connecting pad 12. When the metal sleeve 13 is sleeved with the guide roller 5, the connecting pad 12 is supported. The metal sleeve 13 has magnetic suction. The inner ring wall of the retaining ring 6 is provided with an assembly groove 601, which is fixedly sleeved with the assembly groove 601, so that the retaining ring 6 and the guide roller 5 are firmly magnetically attracted and do not interfere with the guidance of the film.

Please refer to Figures 1 and 3. After the film is guided by the guide roller 5, it passes around the driving roller 7. After the driving roller 7 is driven by the driving device 8 on the outer wall of the frame 1, the film is pulled so that the winding roller 3 can wind it up. The driving device 8 includes a coaxially assembled driving motor 801 and a reduction gear box 802. The reduction gear box 802 is fixedly installed on the outer wall of the frame 1, and the reduction gear box 802 rotates coaxially with the driving shaft. When the driving motor 801 is running, the reduction gear box 802 reduces the speed of the driving motor 801 and increases the output torque to the driving roller 7, so that the driving shaft rotates stably and reliably.

Please refer to Figures 1 and 4. When the connecting frame 2 supports the winding roller 3, the pulley 11 on the winding roller 3 is slidably connected with the slide rail 10 on the connecting frame 2, so that the winding roller 3 moves smoothly and stably along the connecting frame 2. When winding, the winding roller 3 is located in the front part of the connecting frame 2, and the hydraulic rod 9 supports the connecting frame 2 so that its front end has a certain upward tilt angle, so that the winding roller 3 is subject to gravity and moves along the connecting frame 2 and always keeps in contact with the driving roller 7. After the film bypassing the driving roller 7 is connected to the winding roller 3, the driving roller 7 drives the winding roller 3 to rotate by friction transmission when it rotates, so as to wind up the film, and as the thickness of the film increases, the winding roller 3 is pushed to move along the connecting frame 2, but it will not lose contact with the driving roller 7.

Please refer to Figures 2 and 5. After the winding is completed, the connecting frame 2 is pressed down to make its front end horizontal. After the film is cut, the winding roller 3 moves along the connecting frame 2 to its free end. The free end is tilted downward to make the winding roller 3 slide downward along the connecting frame 2. An intercepting frame 4 is movably arranged on the connecting frame 2. Through holes 401 are arranged on both sides of the bottom of the intercepting frame 4. The through holes 401 are slidably connected to the connecting frame 2, and pulleys 11 are also installed in the through holes 401. The pulley 11 is slidably connected to the slide rail 10, so that the movement of the intercepting frame 4 is smooth. After the intercepting frame 4 abuts against the winding roller 3, the winding roller 3 is intercepted, and the intercepting frame 4 is connected with the damping sliding component. The connecting frame 2 is slidably connected to the movement of the winding roller 3 of the intercepting frame 4, providing damping to limit the movement rate of the winding roller 3 along the free end of the connecting frame 2. The damping sliding assembly includes a slide groove 201 arranged on the outer wall of the connecting frame 2 and a bolt 402 threadedly connected to the intercepting frame 4. The bolt 402 abuts against the slide groove 201 to provide damping friction for the intercepting frame 4 to prevent the winding roller 3 from sliding down too fast and causing loss of control, thereby improving the safety of use. After the bolt 402 slides to the end along the slide groove 201, the movement of the intercepting frame 4 is limited, thereby supporting the winding roller 3. At this time, the winding roller 3 slides down to the bottom of the connecting frame 2, and it is labor-saving and simple to remove it.

The working principle of the winding and storage device of the multi-layer film blowing machine is as follows: when winding the film, the front end of the connecting frame 2 is deflected upward along the frame 1 and supported by the hydraulic rod 9, and the winding roller 3 is placed on the connecting frame 2, so that it slides to the front end of the connecting frame 2 under gravity and contacts and fits with the driving roller 7. The extruded film is connected to the winding roller 3 after bypassing the guide roller 5 and the driving roller 7 in turn, and the retaining ring 6 slides along the outer wall of the guide roller 5, and the retaining ring 6 is magnetically attracted to the metal sleeve 13 through the magnet 14, so that the retaining ring 6 is firmly positioned to guide the film, prevent it from swinging, and improve its smoothness of winding;

The winding roller 3 is in contact with the driving roller 7. When the driving roller 7 rotates, the winding roller 3 is driven to rotate in a friction transmission mode to wind up the film. As the thickness of the film increases, the winding roller 3 is pushed to move along the slide rail 10 on the connecting frame 2. The matching arrangement of the pulley 11 and the pulley 11 makes the winding roller 3 move smoothly and maintain stable movement, avoiding the deflection of the winding roller 3, interfering with the winding quality, and improving the reliability of winding;

After the winding is completed and the film is cut off, the front end of the connecting frame 2 is deflected downward along the frame 1 and supported to a horizontal state by the hydraulic rod 9. The winding roller 3 moves along the connecting frame 2 to its free end inclined downward. The winding roller 3 moves downward along the connecting frame 2 under the force of gravity so as to unload it. When the winding roller 3 moves downward, the intercepting frame 4 contacts the winding roller 3, and the bolt 402 on the intercepting frame 4 abuts against the slide groove 201 on the connecting frame 2, providing damping for the intercepting frame 4 and the connecting frame 2, limiting the downward movement rate of the winding roller 3, and preventing the winding roller 3 from getting out of control. After the bolt 402 slides to the end along the slide groove 201, the winding roller 3 is intercepted and continues to move downward. At this time, the winding roller 3 is close to the supporting surface so as to unload it. It is labor-saving and easy to use.
