Description

Technical Field

[0001] This utility model relates to the field of PE film production-related products, specifically a quick material changing device for PE film production. Background Technology

[0002] In PE film production equipment, the extruded PE film passes through the traction station and slitting station, and then to the winding device to wind the PE film onto the winding drum. Existing PE film winding devices require manual clamping and pulling out of the winding rod when winding the PE film onto the winding drum or after winding the finished winding drum. During the replacement process, the PE film production equipment needs to be manually placed on the winding drum of the winding rod, and then the PE film is guided and wound onto the winding drum for winding.

[0003] However, in actual use, replacing the winding drum is quite cumbersome, increasing replacement time and affecting production efficiency, which is a drawback. Utility Model Content

[0004] The purpose of this invention is to provide a quick material changing device for PE film production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick material changing device for PE film production, comprising a base, a vertical plate fixedly connected to the top of one end of the base, a motor fixedly connected to one side of the vertical plate, a support cylinder fixedly connected to the output shaft of the motor, a winding drum provided on the outer side of the support cylinder, a threaded rod rotatably connected inside the support cylinder, the threads on both sides of the center point of the horizontal axial section of the threaded rod having opposite directions, traction plates threadedly sleeved at both ends of the threaded rod, a connecting limiting groove provided on both sides of the support cylinder, a pressure plate provided in the limiting groove, a support block fixedly connected to the inner side wall of the pressure plate, the two ends of the support block being rotatably connected to the traction plate through a connecting plate, a rotating rod fixedly connected to one end of the threaded rod, and a rotating block fixedly connected to one end of the rotating rod penetrating the support cylinder.

[0006] Preferably, the motor is provided with a protective shell on its outer side, the protective shell is fixedly connected to the upright plate, and the protective shell is provided with heat dissipation grooves.

[0007] Preferably, a locking bolt is inserted into one end of the rotating block, and multiple threaded grooves corresponding to the locking bolt are provided on the outer wall of the support cylinder.

[0008] Preferably, the outer wall of the pressure plate is provided with a plurality of conical pressure blocks.

[0009] Preferably, the outer side wall of the rotating block is provided with multiple anti-slip grooves arranged at an angle.

[0010] Preferably, the motor is a servo motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This quick material change device for PE film production works by attaching a take-up drum to a support cylinder. Rotating the rotating block causes a swivel rod to rotate within the support cylinder. As the threaded rod rotates, two traction plates threaded onto it move relative to each other, causing connecting plates at both ends to move. The connecting plates then push a pressure plate within a limiting groove. This limiting groove restricts the pressure plate's sliding movement, causing it to press against the inner wall of the take-up drum. Starting the motor rotates the support cylinder, and the take-up drum rotates along with the support cylinder under the pressure of the pressure plate. This invention, through the setting of the pressure fixing component, facilitates the fixing of the take-up drum, making assembly and disassembly convenient and allowing for easy on-site assembly and use.

[0020] Please see Figure 1-2 This utility model provides an embodiment of a quick material changing device for PE film production, comprising a base 1, a vertical plate 2 fixedly connected to the top of one end of the base 1, a motor 3 fixedly connected to one side of the vertical plate 2, a support cylinder 4 fixedly connected to the output shaft of the motor 3, a winding drum 5 provided on the outer side of the support cylinder 4, a threaded rod 6 rotatably connected inside the support cylinder 4, the threads on both sides of the center point of the horizontal axial section of the threaded rod 6 having opposite directions, traction plates 7 threadedly sleeved at both ends of the threaded rod 6, and connecting limiting grooves on both sides of the support cylinder 4, with a pressing plate 8 provided in the limiting grooves, and a support block 9 fixedly connected to the inner wall of the pressing plate 8, the two ends of the support block 9 communicating with the traction plate 7. The connecting plate 10 is rotatably connected, and one end of the threaded rod 6 is fixedly connected to the rotating rod 11. One end of the rotating rod 11 passes through the support cylinder 4 and is fixedly connected to the rotating block 12. Specifically, rotating the rotating block 12 causes the rotating rod 11 to drive the threaded rod 6 to rotate inside the support cylinder 4. When the threaded rod 6 rotates, the two traction plates 7 threaded on it move relative to each other, thereby causing the connecting plates 10 at both ends to move. At this time, the connecting plate 10 will push the pressure plate 8 to move in the limiting groove. The limiting groove is used to limit the sliding of the pressure plate 8, thereby causing the pressure plate 8 to press against the inner wall of the winding drum 5. The control motor 3 can be started to drive the support cylinder 4 to rotate. At this time, the winding drum 5 rotates with the support cylinder 4 under the pressure of the pressure plate 8.

[0021] In this embodiment, a protective shell 13 is provided on the outer side of the motor 3. The protective shell 13 is fixedly connected to the upright plate 2. The protective shell 13 is provided with heat dissipation grooves to protect the motor 3. A locking bolt 14 is inserted into one end of the rotating block 12. The outer wall of the support cylinder 4 is provided with multiple screw grooves corresponding to the locking bolt 14. The locking bolt 14 is screwed into the corresponding screw groove to realize the rotation and fixation of the rotating block 12. Multiple conical pressing blocks 15 are provided on the outer wall of the pressure plate 8 to increase the fixing effect between it and the inner wall of the winding drum 5. Multiple anti-slip textures are provided on the outer wall of the rotating block 12 in an inclined manner to increase the friction during rotation. The motor 3 is a servo motor 3.

[0022] Working principle: During installation, the take-up drum 5 is first sleeved onto the support drum 4. Then, the rotating block 12 is rotated to cause the rotating rod 11 to drive the threaded rod 6 to rotate inside the support drum 4. When the threaded rod 6 rotates, the two traction plates 7 threaded onto it move relative to each other, thereby causing the connecting plates 10 at both ends to move. At this time, the connecting plates 10 will push the pressure plate 8 to move in the limiting groove. The limiting groove is used to limit the sliding of the pressure plate 8, thereby causing the pressure plate 8 to press against the inner wall of the take-up drum 5. The motor 3 is started to drive the support drum 4 to rotate. At this time, the take-up drum 5 rotates with the support drum 4 under the pressure of the pressure plate 8.

[0023] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
