Description

Technical Field

[0001] The utility model relates to the technical field of film blowing, in particular to a full-automatic film blowing equipment. Background Art

[0002] Film blowing is a plastic processing method that refers to a plastic processing technology that heats and melts plastic particles and then blows them into a film. It usually involves extruding a polymer into a tubular film blank. Under good melt flow conditions, the tubular film is blown to the required thickness using high-pressure air, and then cooled and shaped into a film.

[0003] The known patent application number is: CN202122244448.6, which discloses a fully automatic thickness control device for blown film. Its background technology proposes the problem that "in the existing blow molding machine, the thickness control of the film is generally manual adjustment, but manual adjustment is time-consuming and labor-intensive, and the production efficiency is low; in addition, manual adjustment will also have large errors, affecting the accuracy of the thickness of the product, and easily causing a large amount of waste." Therefore, the technical solution to this problem is "including a first side plate, a second side plate, a blow molding head and a herringbone plate, the ... A top plate is fixedly connected between the top of one side plate and the top of the second side plate, a connecting plate is fixedly connected to one side of the second side plate, a base is fixedly connected to one side of the top of the connecting plate, a thickness detector is installed on the top of the base, an air ring is fixedly connected to the inner wall of the first side plate, a second connecting pipe is fixedly connected to one side of the outer peripheral surface of the air ring, a fixing plate is fixedly connected to one side of the second side plate, a fan is installed on one side of the top of the fixing plate, one end of the fan outlet is fixedly connected to the first connecting pipe, an adjustment box is provided between the first connecting pipe and the second connecting pipe, and an air plate is fixedly connected between the inner walls of the adjustment box.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Example

[0031] See also Figure 1 - Figure 4 The utility model provides a fully automatic film blowing molding equipment, comprising: a fixed frame 1, on which a film blowing molding mechanism is provided;

[0032] A mounting frame 2 fixedly mounted on one side of the fixing frame 1;

[0033] A fixed housing 3 fixedly mounted in the mounting frame 2;

[0034] A movable shell 4 is provided in the mounting frame 2 and is located on one side of the fixed shell 3. The movable shell 4 is adjusted in position by a power member provided on the mounting frame 2.

[0035] The two dust sticking rollers 5 connected to the fixed shell 3 and the movable shell 4 are rotated respectively;

[0036] Two shells 6 are symmetrically fixedly mounted on the top of the fixed shell 3 and the movable shell 4;

[0037] A cleaning sponge plate 7 is slidably connected to the housing 6, wherein sponges are mounted on opposite surfaces of the two cleaning sponge plates 7 by bonding, so as to facilitate subsequent replacement and maintenance;

[0038] A spring 8 fixedly connected to one side of the inner wall of the housing 6 and connected to the cleaning sponge plate 7;

[0039] And a power mechanism is provided on the mounting frame 2 for rotating the dust sticking roller 5 and moving the cleaning sponge plate 7.

[0040] The power mechanism includes a rotating shaft 10 rotatably connected to one side of the inner wall of the mounting frame 2, two synchronous wheels 11 fixedly connected to one end of the rotating shaft 10 and one end of the dust-sticking roller 5 located in the fixed shell 3, a synchronous belt 12 tensioned and engaged on the surface of the two synchronous wheels 11, a rotating rod 13 fixedly mounted on the surface of the rotating shaft 10, a protrusion 14 fixedly mounted on one end surface of the two shells 6 and cooperating with the rotating rod 13, and a driving member provided on the mounting frame 2.

[0041] The driving member includes a motor 15 fixedly mounted on one side of the mounting frame 2 , and an output end of the motor 15 movably passes through the mounting frame 2 and is connected to the other end of the dust-sticking roller 5 located in the fixed shell 3 .

[0042] The technical solution provided by this embodiment is as follows: when in use, the raw materials are squeezed into the film blowing molding mechanism through an external extruder, so that the film blowing molding mechanism forms the film, and the formed film is introduced into the installation frame 2 and passed between the two sticky rollers 5. The movable shell 4 is then driven by the power member to move toward the fixed shell 3, so that the two sticky rollers 5 and the cleaning sponge plate 7 are in contact with both sides of the film, and finally the film is transferred to the subsequent equipment for processing. During this process, the film is moved and transported, and at the same time, the motor 15 drives one sticky roller 5 and the synchronous wheel 11 at its end to rotate, and the synchronous belt 12 drives the other synchronous wheel 11 to rotate, so that the rotating shaft 10 and the rotating rod 1 3 rotates, and the rotating rod 13 rotates to contact the two protrusions 14 and cause squeezing, thereby driving the two cleaning sponge plates 7 to move and compress the spring 8. When the rotating rod 13 is separated from the protrusion 14, the spring 8 drives the cleaning sponge plate 7 to move and reset. Such a cycle can make the cleaning sponge plate 7 move back and forth in a small amplitude to clean the film efficiently and prevent stubborn impurities and dust from remaining. The film can then be cleaned again by the rotating dust-sticking roller 5, further improving the cleaning effect. Therefore, the dust and impurities attached to the surface of the film can be cleaned, and the dust and impurities can be prevented from affecting the subsequent processing of the film, thereby effectively improving the quality and work efficiency of the film forming process.

[0043] Furthermore, the power component includes an electric push rod 9 fixedly mounted on a side of the mounting frame 2, and an output end of the electric push rod 9 movably passes through the mounting frame 2 and is connected to the movable shell 4.

[0044] Specifically: the movable shell 4 can be driven to move by the electric push rod 9, so that the dust-sticking roller 5 inside it can move closer to or away from the dust-sticking roller 5 in the fixed shell 3, so as to adjust the distance between the cleaning parts on both sides according to the thickness of the film, thereby improving the flexibility of use.

[0045] Furthermore, the film blowing molding mechanism includes a film blowing component 16 fixedly mounted on the inner bottom wall of the fixed frame 1, connecting plates 17 symmetrically fixedly mounted on both sides of the inner wall of the fixed frame 1, adjusting plates 18 symmetrically hinged on the top of the two connecting plates 17, a molding roller 19 rotatably connected to the top of the two adjusting plates 18, and a thickness adjustment component provided on the fixed frame 1 for adjusting the angle of the two adjusting plates 18. A through groove for the film to pass through is provided on the top of the fixed frame 1.

[0046] The thickness adjustment component includes two electric push rods 20 symmetrically fixed on both sides of the inner wall of the fixed frame 1, and the output ends are movably connected to the two adjustment plates 18, and a thickness detector 21 fixedly mounted on the top of the fixed frame 1. Among them, the thickness detector 21 and the film blowing component 16 are both existing technologies and will not be described in detail here.

[0047] Specifically: when blowing film, the raw materials are extruded into the film blowing component 16 through an external extruder, and the plastic body is blown into a cylindrical shape by the wind force blown out from the outside. The two adjustment plates 18 of the film are then rolled into shape under the extrusion of the forming roller 19. The formed film is then passed through a thickness detector 21 and then transmitted to the next device through the installation frame 2 for subsequent processing. During the process, the thickness of the film can be monitored in real time by the thickness detector 21. When it is detected that the film is thicker, the two adjustment plates 18 are driven by the electric push rod 20 to rotate closer to each other, changing the angle between the two, so as to shorten the distance between the two forming rollers 19. On the contrary, when it is thinner, the two adjustment plates 18 are driven away from the forming roller 19 to increase the distance between the forming rollers 19, thereby achieving the effect of adjusting the thickness of the film forming.

[0048] Furthermore, the top of the fixed frame 1 and one side of the thickness detector 21 is rotatably connected to a guide roller 22 through a base block 1, and one side of the fixed frame 1 and above the mounting frame 2 is rotatably connected to a guide roller 23 through a base block 2.

[0049] Specifically, by providing the guide roller 1 22 and the guide roller 2 23 , the formed film can be guided so as to enter the installation frame 2 for cleaning.

[0050] It should be noted that: the device is equipped with a controller to control the electrical components and detection components in the device, thereby achieving an automated effect.

[0051] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
