Description

Technical Field

[0001] The utility model relates to the technical field of plastic film anti-deviation, in particular to an auxiliary mechanism for preventing plastic film from deviating and getting stuck, which is used in a film blowing machine. Background Art

[0002] Plastic film blowing machine is a kind of equipment used to manufacture plastic film. Its main function is to heat and melt plastic particles and form them into film by blowing. Plastic raw materials are added to the equipment through the barrel, and then the raw materials are heated to melt and have a certain fluidity. Under the action of the extruder, the molten plastic forms a continuous film through the die. Air is injected into the film through the blowing device to make it bulge up to the same shape as the mold. The bulging film is fixed by the herringbone plate and continuously pulled out by the traction device. Finally, it is rolled into the required film product. During the rolling process, the plastic film may deviate, affecting the stability of the plastic film rolling.

[0003] Chinese patent CN220883395U discloses an anti-deviation mechanism for a plastic film blowing machine. The anti-deviation mechanism of the plastic film blowing machine includes: a machine base, on which a plurality of electric hydraulic rods for blowing a plastic film are arranged, and the plurality of electric hydraulic rods are symmetrically fixedly mounted on the top of the machine base; an assembly plate, which is fixedly mounted on the top of the plurality of electric hydraulic rod output rods; and a mounting shell, which is fixedly mounted on the top of the assembly plate. The patent sets an anti-deviation mechanism, which includes two U-shaped guide frames, which are in contact with the edge of the plastic film, and limit the deviation of the film when the plastic film moves.

DETAILED DESCRIPTION

[0025] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0026] Reference Figure 1-Figure 6 As shown, the utility model provides an auxiliary mechanism for preventing plastic film from deflecting and getting stuck for a film blowing machine, comprising a main body 1, a film blowing machine body 11 is fixed on one side of the top of the main body 1, a conveying device 12 for supporting plastic film is arranged at the top of the main body 1 near the discharge end of the film blowing machine body 11, an anti-deviation component 13 for preventing the plastic film from deflecting is arranged at the top of the main body 1 near the conveying device 12, a winding component 14 for winding the plastic film is arranged at the top of the main body 1 near the anti-deviation component 13, and the anti-deviation component 13 includes a first anti-deviation roller 1341 and a second anti-deviation roller 136 that can move along the width direction of the plastic film, the first anti-deviation roller 1341 and the second anti-deviation roller 136 clamp the plastic film and adjust the position of the plastic film, and the first anti-deviation roller 1341 and the second anti-deviation roller 136 can move along the width direction of the plastic film, thereby adjusting the position of the plastic film. It can ensure that the plastic film always remains on the predetermined path to avoid deviation. This design allows flexible adjustment of plastic films of different widths and thicknesses.

[0027] The anti-deviation assembly 13 includes a support frame 134 for supporting a first anti-deviation roller 1341, and a first lifting mechanism 135 for the up and down movement of a second anti-deviation roller 136 is arranged on the support frame 134. The first lifting mechanism 135 is used to control the up and down movement of the second anti-deviation roller 136. This design allows the position of the second anti-deviation roller 136 to be accurately adjusted according to the thickness, material or tension requirements of the plastic film. The first lifting mechanism 135 can be in various forms, such as pneumatic, electric or hydraulic drive, to provide the required adjustment range and accuracy.

[0028] The first lifting mechanism 135 includes a second telescopic driving member 1351 fixed to the top of the support frame 134, the output end of the second telescopic driving member 1351 passes through the support frame 134 and is connected to the lifting plate 1352, the top of the lifting plate 1352 is evenly distributed with first guide rods 1353, the first guide rods 1353 are slidably matched with the support frame 134, the second anti-deviation roller 136 is rotatably arranged on the lifting plate 1352 along the width direction of the lifting plate 1352, and the second telescopic driving member 1351 serves as a power source for the first lifting mechanism 135. The second telescopic driving member 1351 can be an electric, pneumatic or hydraulic driver, which can provide sufficient driving force to move the lifting plate 1352 and the second anti-deviation roller 136 thereon.

[0029] The anti-deviating assembly 13 includes a moving mechanism 133 for reciprocating the support frame 134 along the width direction of the plastic film. The anti-deviating assembly 13 includes a first telescopic driving member 131 fixed on the main body 1. A support plate 132 is fixed on the top of the first telescopic driving member 131. The moving mechanism 133 is arranged on the support plate 132. The moving mechanism 133 includes a lead screw 1332 that is rotatably arranged along the length direction of the support plate 132. The moving mechanism 133 also includes a first rotating driving member 1331 that is fixed on the support plate 132 and used to drive the lead screw 1332 to rotate. The output end of the first rotating driving member 1331 is fixedly connected to the lead screw 1332. The lead screw 1332 is connected to the support frame 134 by threads. The support plate 132 and the support frame 134 are connected by slide rails and sliders. The first rotating driving member 1331 can be a motor or a similar driver that can provide sufficient torque to rotate the lead screw 1332.

[0030] The anti-deviation assembly 13 is mainly composed of a first anti-deviation roller 1341 and a second anti-deviation roller 136, which work together to clamp the plastic film. The first anti-deviation roller 1341 and the second anti-deviation roller 136 move synchronously to effectively correct the deviation of the plastic film. During the transmission of the plastic film, once deviation occurs, the first anti-deviation roller 1341 and the second anti-deviation roller 136 will move immediately to adjust the position of the plastic film in time to ensure that the plastic film can be neatly wound on the winding roller 141.

[0031] refer to Figure 5 and Figure 6 As shown, the winding assembly 14 includes a winding support 145 fixed to the top of the main body 1, a winding roller 141 is rotatably provided on the winding support 145, a second rotating driving member 142 for driving the winding roller 141 to rotate is also fixed to the outside of the winding support 145, and the output end of the second rotating driving member 142 is fixedly connected to the winding roller 141. The winding assembly 14 also includes a pressing assembly 144 for pressing the film on the winding roller 141, and the winding assembly 14 also includes a second lifting mechanism 143 for driving the pressing assembly 144 to move up and down.

[0032] When the plastic film passes through the winding assembly 14, the plastic film is first guided to the winding roller 141. The second rotary drive member 142 starts to work, driving the winding roller 141 to rotate. The pressing assembly 144 is adjusted to the plastic film contact position through the second lifting mechanism 143 to ensure that the film can be pressed on the winding roller 141.

[0033] The second lifting mechanism 143 includes a third telescopic driving member 1431 fixed on the top of the winding assembly 14. The output end of the third telescopic driving member 1431 passes through the winding bracket 145 and is connected to the lifting frame 1432. A second guide rod 1433 is fixed on the top of the lifting frame 1432. The second guide rod 1433 passes through the winding bracket 145 and extends out. The pressing assembly 144 includes a pressure roller support 1441. A pressure roller body 1442 is rotatably arranged on the pressure roller support 1441. A moving rod 1443 is arranged on the top of the pressure roller support 1441 along its length direction. The moving rod 1443 is slidably arranged on the lifting frame 1432 in the second lifting mechanism 143. A spring 1444 is sleeved on the outside of the moving rod 1443. One end of the spring 1444 is connected to the pressure roller support 1441, and the other end of the spring 1444 is connected to the lifting frame 1432.

[0034] When the third telescopic driving member 1431 is activated, the third telescopic driving member 1431 will start to telescope, thereby driving the lifting frame 1432 to move up and down. As the lifting frame 1432 moves, the pressing assembly 144 (including the pressure roller support member 1441, the pressure roller body 1442 and the moving rod 1443) will also move up and down accordingly. The spring 1444 provides additional pressing force between the pressure roller support member 1441 and the lifting frame 1432 to ensure that the plastic film can be tightly pressed on the winding roller 141.

[0035] During the plastic film winding process, the pressure roller body 1442 will descend and press the plastic film onto the winding roller 141. As the size of the plastic film roll on the winding roller 141 gradually increases, the force of the spring 1444 will keep the pressure roller body 1442 on the plastic film to prevent the plastic film roll from unraveling due to being too loose.

[0036] Working principle: When in use, the raw materials for making the plastic film are first poured into the film blowing machine body 11. Subsequently, the film blowing machine body 11 melts the raw materials and processes them into plastic film. The plastic film then passes through the gap between the second anti-deviation roller 136 and the first anti-deviation roller 1341, and is finally wound around the winding roller 141. In order to clamp the plastic film, the second telescopic driving member 1351 is started, and the second telescopic driving member 1351 moves the lifting plate 1352 downward, thereby driving the second anti-deviation roller 136 to move downward, and clamp the plastic film together with the first anti-deviation roller 1341. If the plastic film deviates during the transmission process, the first rotating driving member 1331 is started, and the first rotating driving member 1331 rotates the lead screw 1332, thereby driving the support frame 134 to move. This movement causes the second anti-deviation roller 136 and the first anti-deviation roller 1341 to move accordingly, and the position of the plastic film is corrected in real time. In addition, the vertical positions of the second anti-deviation roller 136 and the first anti-deviation roller 1341 can be adjusted through the first telescopic driving member 131 to adapt to the height of the plastic film. In the plastic film winding stage, the third telescopic driving member 1431 is started, and the third telescopic driving member 1431 moves the lifting frame 1432 downward, thereby causing the pressure roller body 1442 to press the plastic film on the winding roller 141. As the size of the plastic film roll on the winding roller 141 gradually increases, the force of the spring 1444 ensures that the pressure roller body 1442 is always tightly pressed on the plastic film, preventing the plastic film roll from being loosened due to being too loose.

[0037] The above embodiments only express one or several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be based on the attached claims.
