Technical Field

[0001] The utility model relates to the technical field of film winding, in particular to a novel winding device. Background Art

[0002] Winding equipment is a mechanical method to roll up materials such as films into coils for subsequent processing. Film products such as polyethylene films need to be rolled up by a winder during production and wound around a winding roller. When the existing winding equipment completes the winding work of a winding roller and replaces the new winding roller, it cannot continue to wind and needs to wait for a period of time. The replacement time interval is long, which easily leads to the accumulation and waste of polyethylene film. Therefore, a winding device is needed that is easy to quickly replace the winding shaft and ensure the continuity of the winding work. Utility Model Content

A through groove is opened in the middle of the support platform, and a push-pull plate is fixedly connected to the middle of the lower surface of the sliding frame. The push-pull plate slides through the through groove and is fixedly connected to the telescopic end of an electric telescopic rod. The electric telescopic rod is fixedly installed on the lower surface of the support platform, and two limit switches are fixedly connected to the side of the through groove. The two limit switches correspond to the push-pull plates. The sliding frame is driven by the electric telescopic rod to move on the support platform, and the moving position of the sliding frame is controlled by the limit switch. The top of the roller shaft mounting frame is provided with a sliding groove, in which a rolling shaft is slidably mounted with a buckle in the sliding groove, and a rotating buckle joint is rotatably mounted on the roller shaft mounting frame just below the rolling shaft, and the rotating buckle joint comprises a round shaft rotatably mounted on the roller shaft mounting frame, and the rotating buckle joint comprises a round shaft rotatably mounted on the roller shaft mounting frame, and one end of the round shaft is a square shaft section, and a square hole sleeve is slidably mounted on the square shaft section, and a first spring is pressed between one end of the square hole sleeve and the end of the round shaft, and the first spring is slidably connected to the square shaft section, and a baffle is fixedly connected to the other end of the square hole sleeve circumferentially, and a winding shaft is buckled and plugged between the corresponding two rotating buckle joints. Square shaft heads are fixedly connected at both ends of the winding shaft, and the corresponding buckle of the square shaft head is plugged into the square hole of the square hole sleeve, and the winding shaft and the rotating buckle joints at both ends are connected as a whole through the square hole sleeve and rotate on the roller shaft mounting frame. The square hole sleeve is pushed away from the winding shaft, so that the square hole sleeve is separated from the winding shaft, and the winding shaft can be taken out. After the square hole sleeve is released, it will be reset under the action of the first spring restoring force, so that a new winding shaft can be installed. The winding shaft is located directly below the rolling shaft. During the film winding process, the rolling shaft will always roll and press on the film roll under the action of its own weight, so that the film can be wound more smoothly and tightly.

[0004] The cam is provided with a plurality of guide wheels, each guide wheel is provided with a plurality of guide wheels, each guide wheel being provided with a plurality of guide wheels respectively connected to the plurality of guide wheels, and a plurality of guide wheels are provided at the plurality of guide wheels respectively connected to the plurality of guide wheels. Brackets are fixedly connected at both ends of the support platform, and the brackets correspond to the lower edges of the guide plates. After the winding shaft is completed, it will detach from the rotating snap joint, fall onto the guide plate and roll onto the brackets, so that it is easy to carry it away directly.

[0005] As a preferred solution of the utility model, the two ends of the rolling shaft are rotatably connected with a snap-on slider, and the snap-on slider is slidably snap-installed in the slide groove. The snap-on slider can make the rolling shaft rotate and slide up and down in the slide groove, so that under the action of its own weight, the rolling shaft can always be pressed downward on the winding shaft.

As a result, the guide push plate presses the baffle to press the square hole sleeve backwards, and the first spring is synchronously compressed. The square hole sleeves at both ends of the winding shaft move under the synchronous push of the guide push plate, thereby synchronously separating from the winding shaft, so that the winding shaft separates from the rotating snap joint and falls onto the guide plate. After the sliding frame stops moving, the baffle separates from the guide push plate, and the first spring rebounds the square hole sleeve to reset it, so that the new winding shaft can be installed on the rotating snap joint.

The rear side of the baffle presses on the front side of the guide push plate and slides, so that the baffle presses the guide push plate to slide the push rod backward on the slide rod, and the second spring is compressed synchronously, while the square hole sleeve does not slide, thereby ensuring that the winding shaft does not separate from the square hole sleeve. After the baffle separates from the guide push plate, the guide push plate and the push rod are reset under the action of the restoring force of the second spring.

[0007] As a preferred solution of the utility model, the two ends of the upper edge of the guide plate are fixedly connected with plug-in sleeves, the plug-in sleeves correspond to the positioning pin holes, and are plugged and fixed by pins. The arc-shaped arrangement of the positioning pin holes allows the plug-in sleeves to correspond to the positioning pin holes during the rotation of the guide plate, which is convenient for the plug-in pins to fix, and the guide plate can be rotated to adjust its inclination and the distance from the winding shaft, so that the guide plate can be adjusted according to the thickness of the winding shaft after winding, so that the winding shaft after winding can fall smoothly onto the guide plate.

After one winding shaft completes winding, the sliding frame can quickly switch to another winding shaft. The two groups of winding shafts are respectively connected to the motor drive at the winding station to carry out the winding work, and the winding shaft that has completed winding will move to the side to complete the unloading and replacement of the new winding shaft, so as not to affect the winding work and improve the winding efficiency. The winding shaft is fixed by the designed rotating snap joint. When the sliding frame drives the winding shaft to move, the unloading push plate can be used to move the square hole sleeve on the rotating snap joint, so that the winding shaft that has completed winding automatically detaches from the rotating snap joint, falls onto the guide plate and finally falls on the bracket to complete the automatic unloading work. The staff only needs to install the new winding shaft into the rotating snap joint. The entire device improves the replacement speed of the winding shaft, ensures the continuity of the winding work, and improves production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] Example 1

[0017] like Figures 1 to 6 As shown, a new type of winding device of the utility model is provided, in which a sliding frame 4 is slidably installed on the upper surface of a support platform 1 through a sliding rail 13, and two groups of roller mounting frames 401 are fixedly connected to each other on both sides of the sliding frame 4, and each two corresponding roller mounting frames 401 form a group, and a rolling shaft 8 and a winding shaft 7 are installed between them, and two groups of rolling shafts 8 and winding shafts 7 are symmetrically installed on the sliding frame 4. A through slot 103 is provided in the middle of the support platform 1, and a push-pull plate 404 is fixedly connected to the middle of the lower surface of the sliding frame 4. The push-pull plate 404 slides through the through slot 103 and is fixedly connected to the telescopic end of the electric telescopic rod 11. The electric telescopic rod 11 is fixedly installed on the lower surface of the support platform 1. Two limit switches 12 are fixedly connected to the side of the through slot 103. The two limit switches 12 correspond to the push-pull plate 404. The sliding frame 4 is driven by the electric telescopic rod 11 to move on the support platform 1. The moving position of the sliding frame 4 is controlled by the limit switch 12 to ensure that the electric telescopic rod 11 pushes the sliding frame 4 through telescoping, and moves the two sets of rolling shafts 8 and the winding shaft 7 to the winding position respectively, so that the corresponding driven gear 5 is engaged with the driving gear 3. The roller mounting frame 401 is provided with a slide groove 402 on the top, and a rolling shaft 8 is installed by sliding buckle in the slide groove 402. Buckle sliders 801 are rotatably connected at both ends of the rolling shaft 8. The buckle sliders 801 are slidably buckled and installed in the slide groove 402. The rolling shaft 8 can rotate and slide up and down in the slide groove 402 through the buckle sliders 801. A rotating buckle joint 6 is rotatably installed on the roller mounting frame 401 just below the rolling shaft 8. The rotating buckle joint 6 includes a round shaft 601 rotatably installed on the roller mounting frame 401. One end of the round shaft 601 is a square shaft section 605. The square shaft section 605 slides upward. The movable buckle is installed with a square hole sleeve 603, and a first spring 602 is pressed between one end of the square hole sleeve 603 and the end of the round shaft 601, and the first spring 602 is slidably connected to the square shaft section 605. The other end of the square hole sleeve 603 is circumferentially fixedly connected with a baffle 604, and a winding shaft 7 is buckled and inserted between the corresponding two rotating buckle joints 6. Square shaft heads 701 are fixedly connected at both ends of the winding shaft 7, and the square shaft heads 701 are correspondingly buckled and inserted in the square holes of the square hole sleeve 603. The winding shaft 7 and the rotating buckle joints 6 at both ends are connected as a whole through the square hole sleeve 603 and rotate on the roller mounting frame 401. Pushing the square hole sleeve 603 away from the winding shaft 7 will cause the square hole sleeve 603 to disengage from the winding shaft 7, thereby allowing the winding shaft 7 to be taken out. After releasing the square hole sleeve 603, it will be reset under the restoring force of the first spring 602, thereby facilitating the installation of a new winding shaft 7.

[0018] The winding shaft 7 is located directly below the rolling shaft 8. During the film winding process, the rolling shaft 8 will always roll and press on the film roll wound on the winding shaft 7 under the action of its own weight, so that the film can be wound more smoothly and tightly. The side of the sliding frame 4 is fixedly mounted with a motor 2 on the upper surface of the support platform 1 through a motor mounting seat 101. A driving gear 3 is fixedly connected to the rotating shaft of the motor 2. A driven gear 5 is fixedly connected to the outer end of the rotating snap joint 6 on the same side as the driving gear 3. The driven gear 5 is fixedly connected to the corresponding end of the circular shaft 601. The driving gear 3 and the driven gear 5 are correspondingly matched in transmission. During the left and right movement of the sliding frame 4, the two driven gears 5 will be meshed with the driving gear 3 respectively, so that the motor 2 drives the rotating snap joint 6 and the winding shaft 7 to rotate through the cooperation of the driving gear 3 and the driven gear 5.

[0019] Each of the rotating snap joints 6 is correspondingly provided with a discharge push plate 9, and the discharge push plate 9 includes a fixed plate 901 fixedly connected to the support platform 1, and two sliding rods 902 are fixedly connected to the upper end of the fixed plate 901, and a pushing rod 904 and a second spring 903 are slidably passed through the sliding rod 902, and the two ends of the second spring 903 are respectively pressed on the pushing rod 904 and the fixed plate 901, and a guide push plate 905 is fixedly connected to the upper surface of the end of the pushing rod 904, and the guide push plate 905 is inclined relative to the sliding direction of the sliding frame 4, and the side surface of the baffle 604 on one side of the winding shaft 7 corresponds to the rear side surface of the front end of the guide push plate 905. After the winding shaft 7 completes winding, during the process of moving sideways driven by the sliding frame 4, the front side of the baffle 604 presses on the rear side of the guide push plate 905 and slides, so that the guide push plate 905 presses the baffle 604 to press the square hole sleeve 603 backward, and synchronously compresses the first spring 602. The square hole sleeves 603 at both ends of the winding shaft 7 move under the synchronous push of the guide push plate 905, thereby synchronously disengaging from the winding shaft 7, causing the winding shaft 7 to disengage from the rotating snap joint 6 and fall onto the guide plate 10. After the sliding frame 4 stops moving, the baffle 604 disengages from the guide push plate 905, and the first spring 602 rebounds and resets the square hole sleeve 603, so that the new winding shaft 7 can be installed on the rotating snap joint 6. After the other group of winding shafts 7 completes winding, the sliding frame 4 moves in the reverse direction, so that the replaced winding shaft 7 moves synchronously toward the motor 2, and the rear side of the baffle 604 presses on the front side of the guide push plate 905 to slide, so that the baffle 604 presses the guide push plate 905 to slide the push rod 904 backward on the slide rod 902, and the second spring 903 is compressed synchronously, and the square hole sleeve 603 does not slide, so as to ensure that the winding shaft 7 does not separate from the square hole sleeve 603, and after the baffle 604 separates from the guide push plate 905, the guide push plate 905 and the push rod 904 are reset under the restoring force of the second spring 903. Therefore, during the movement of the sliding frame 4, the winding shaft 7 that has been wound is disassembled by pushing the rotary buckle joint 6 by the unloading push plate 9, and it is ensured that the replaced winding shaft 7 will not be affected by the unloading push plate 9 when it moves in the reverse direction with the sliding frame 4.

[0020] The lower part of the roller mounting frame 401 is provided with positioning pin holes 403 arranged in an arc shape, and the two ends of the sliding frame 4 are equipped with guide plates 10 through hinge rotation. The guide plates 10 are arranged obliquely below the winding shaft 7, and the two ends of the upper edge of the guide plate 10 are fixedly connected with plug sleeves 1001, which correspond to the positioning pin holes 403 and are plugged and fixed by pin shafts 1002. The arc-shaped arrangement of the positioning pin holes 403 allows the plug sleeves 1001 to correspond to the positioning pin holes 403 during the rotation of the guide plate 10, which is convenient for the plugging of the pin shaft 1002 for fixing, and the guide plate 10 can be rotated to adjust its inclination and the distance from the winding shaft 7, so that the guide plate 10 can be adjusted according to the thickness of the winding shaft 7 after winding, so that the winding shaft 7 after winding can fall onto the guide plate 10 smoothly. The two ends of the support platform 1 are fixedly connected with brackets 102, and the brackets 102 correspond to the lower edge of the guide plate 10. After the winding shaft 7 completes the winding, it moves to the side with the sliding frame 4 and is detached from the rotating snap joint 6 by the pressure of the unloading push plate 9, and will fall onto the guide plate 10 and roll onto the bracket 102, so as to facilitate direct transportation.
