Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aluminum-plastic film processing devices, in particular to an aluminum-plastic film winding mechanism. Background Technique
[0002] An aluminum-plastic film is a film structure with a thin aluminum layer covered on the surface, which has good ductility and excellent heat insulation performance. Therefore, some of its application scenarios are for covering heat insulation materials on the outside, such as: the inner lining of takeaway boxes, food packaging bags, etc.
[0003] In the prior art devices, in order to improve the heat insulation effect, some heat insulation cotton is generally adhered to the inner wall of the aluminum-plastic film. This can improve the buffering and shock absorption effects and further prevent heat dissipation.
[0004] However, after adhering the heat insulation cotton to the inner wall, the thickness and deformation ability of the aluminum-plastic film itself will be significantly improved. This makes it impossible for the adjacent layers of aluminum-plastic films to fully fit during the winding and sorting process of a large number of aluminum-plastic films. At this time, if the stretching distance of the compensating part in the conventional winding device is increased to make the aluminum-plastic film fully taut, the frictional loss will be large, and the aluminum layer on the outer surface of the aluminum-plastic film will be overstretched, thus reducing the expected effect.
[0005] In the prior art devices, most operators tend to force the adjacent layers of aluminum-plastic films to fit by pressing with their palms. However, this also increases the risk of operator injury, and the operator's fingers are easily caught between the aluminum-plastic film and the aluminum-plastic film roller. Therefore, we believe that an aluminum-plastic film winding mechanism with an auxiliary limiting mechanism that can limit the position of the operator's fingers is needed. Summary of the Invention
[0006] Aiming at the deficiencies in the prior art, the utility model proposes an aluminum-plastic film winding mechanism, which has the advantage of fully avoiding the operator from being pressed against the aluminum-plastic film roller and avoiding injury, and solves the disadvantages of high processing risk and easy operator injury in the prior art devices.
[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:
[0008] A kind of aluminum-plastic film winding mechanism comprises a support frame whose horizontal plane projection is U-shaped and the U-shaped opening faces left, a front-rear axial driving motor I is fixedly connected to the inner side of the rear end of the support frame, a winding roller is coaxially fixedly connected to the output shaft of the driving motor I, a front-rear axial limiting roller is arranged on the right side of the winding roller, a positioning rod is rotatably connected to both sides of the limiting roller, and each positioning rod is rotatably connected to the inner side wall of the support frame at one end away from the limiting roller, a front-rear axial connecting rod is arranged on the right side of the limiting roller, two axial ends of the connecting rod are respectively abutted against the upper end surface of the positioning rod, and two axial ends of the connecting rod are respectively fixedly connected to a driving rod, each middle section of the driving rod is rotatably connected to a mounting frame through a pin shaft, the mounting frame is rotatably connected to the inner side wall of the support frame, and the height of the central axis of the pin shaft is greater than the height of the central axis of the connecting piece.
[0009] Preferably, a push plate is sleeved on the outer side of the winding roller, and an internal threaded hole in the front-rear axial direction is penetrated through the lower end of the push plate, a screw rod is threaded in the internal threaded hole, and the screw rod is rotatably connected to the support frame.
[0010] Preferably, an internal threaded hole is respectively formed on the left and right sides of the lower end of the push plate, and a screw rod is threaded in each internal threaded hole. A drive motor II is arranged between the two screw rods, and the output shaft of the drive motor II is connected to the two screw rods through a gear set.
[0011] Preferably, a tension spring is arranged on the side of each positioning rod away from the winding roller, and the two axial ends of each tension spring are respectively slidably connected to the adjacent positioning rod and the support frame. When the tension spring is not affected by external force, the limiting roller does not contact the winding roller.
[0012] Preferably, two axial ends of the connecting rod are coaxially fixedly connected with a bearing, and the outer ring of the bearing abuts against the positioning rod.
[0013] Preferably, the angle between the vertical center line of each driving rod and the inner side wall of the right end of the support frame is greater than ninety degrees, and the two driving rods are respectively fixedly connected to a handle at the distal ends.
[0014] Compared with the prior art, the utility model has the following beneficial effects:
[0015] The utility model compresses the aluminum-plastic film with the assistance of the limiting roller, so as to force the aluminum-plastic films of adjacent layers to fit closely together, which replaces the traditional manual method and can fully prevent the operator's fingers from being caught between the aluminum-plastic film roller and the aluminum-plastic film, thereby preventing the operator from being injured.
[0016] The utility model drives the limiting roller to move toward the winding roller through the driving rod. This can fully ensure that the user's hand needs to continuously exert force on the driving rod during the actual processing process in a manual manner. This is a fool-proof design of the device and can further ensure the safety of the operator. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.
[0024] Please refer to Figures 1-4 , an aluminum-plastic film winding mechanism, including a support frame 1 with a U-shaped horizontal plane projection and a left-facing U-shaped opening. In practice, the support frame 1 is the workbench in the conventional sense. For the convenience of description of this device, the workbench is simplified to the form of the support frame 1.
[0025] Consistent with the prior art device, a driving motor I 4 with an axial direction from front to back is fixedly connected to the inner side of the rear end of the support frame 1, and a winding roller 2 is coaxially and fixedly connected to the output shaft of the driving motor I 4. This drives the winding roller 2 through the driving motor I 4 to wind the aluminum-plastic film.
[0026] It should be noted that as shown in the figure, the winding roller 2 is in a hollow shape, and through grooves are formed through the winding roller 2. By means of the through grooves, the aluminum-plastic film can form an initial winding state during the rotation of the winding roller 2 by using friction without the need for additional equipment. This also enables the device to be applied to the winding process of the aluminum-plastic film in a state without an inner core.
[0027] Different from the prior art device, a limiting roller 5 in the front-back axial direction is arranged on the right side of the winding roller 2 of this device. By changing the distance between the limiting roller 5 and the winding roller 2, the outer end face of the limiting roller 5 can be closely attached to the outermost aluminum-plastic film during the winding process of the aluminum-plastic film. This can effectively prevent multiple layers of aluminum-plastic film from not being tightly wound due to the influence of centrifugal force, which may cause the overall device to require manual intervention and lead to unexpected situations.
[0028] Specifically, a positioning rod 6 is rotatably connected to both sides of the limiting roller 5 respectively, and one end of each positioning rod 6 far away from the limiting roller 5 is rotatably connected to the inner side wall of the support frame 1. Therefore, by rotating the positioning rod 6, the limiting roller 5 can rotate synchronously around a certain point, and during this process, the height and horizontal position of the limiting roller 5 can be changed.
[0029] As shown in the figure, this device restricts the included angle between the vertical center line of the positioning rod 6 and the right inner end face of the support frame 1 to be less than 90 degrees, and moreover, restricts the height of the central axis of the limiting roller 5 to be greater than the height of the central axis of the winding roller 2. This can fully achieve the purpose of changing the distance between the outer end face of the limiting roller 5 and the outer end face of the winding roller 2 during the counterclockwise rotation of the positioning rod 6.
[0030] At the same time, the rotatable connection between the limiting roller 5 and the positioning rod 6 also enables when the aluminum-plastic film is wound on the outside of the winding roller 2, the outermost aluminum-plastic film abuts against the limiting roller 5, and when multiple layers of aluminum-plastic film rotate at a high speed under the influence of the winding roller 2, a rotational process with opposite movements can be formed between the aluminum-plastic film and the limiting roller 5. This can prevent the aluminum-plastic film from being directly relatively slid and being subjected to a large vertical direction tensile force, and can effectively prevent the aluminum-plastic film from being damaged.
[0031] Furthermore, in order to ensure that the limiting roller 5 can fit the outermost aluminum-plastic film and ensure that adjacent layers of aluminum-plastic film can be closely attached, a connecting rod 8 in the front-back axial direction is arranged on the right side of the limiting roller 5 of this device. By restricting the two axial ends of the connecting rod 8 to abut against the upper end faces of the positioning rods 6 respectively, the angle of the driven rod can be controlled by changing the position of the connecting rod 8, thereby realizing the control of the position of the limiting roller 5.
[0032] Specifically, a driving rod 12 is fixedly connected to each of the two axial ends of the connecting rod 8 of this device. By restricting the middle section of each driving shaft to be rotatably connected to an installation frame 13 through a pin shaft 15, and the installation frame 13 is rotatably connected to the inner side wall of the support frame 1.
[0033] At this time, it is only necessary to further restrict the height of the central axis of the pin shaft 15 to be greater than the height of the central axis of the connecting member, so that during the clockwise rotation of the driving rod 12, the connecting rod 8 moves towards the positioning rod 6, thereby forcing the positioning rod 6 to rotate counterclockwise, changing the distance between the limiting roller 5 and the winding roller 2.
[0034] At the same time, this not only enables the driving rod 12 to have a shorter movement stroke for easy operation, but also makes the reaction force of the positioning rod 6 on the driving rod 12 obvious enough to prevent the user from pulling the driving rod 12 to cause the downward pressure exerted by the limiting roller 5 on the winding roller 2 to be too large, and to avoid excessive resistance during the rotation of the winding roller 2.
[0035] Furthermore, in order to reduce the frictional resistance during the relative movement between the connecting rod 8 and the positioning rod 6, a bearing 7 is coaxially and fixedly connected to each axial end of the connecting rod 8 of this device, and the outer ring of the bearing 7 is constrained to abut against the positioning rod 6, thereby preventing relative sliding between the connecting rod 8 and the positioning rod 6.
[0036] Furthermore, in order to facilitate the user to control the position of the driving rod 12, a handle 14 is fixedly connected to each driving rod 12 of this device.
[0037] At the same time, in order to further restrict the positions of the operator's hands, this device restricts the two handles 14 to be respectively located at the far ends of the two driving rods 12, and the distance between the two driving rods 12 is also relatively large. This makes it necessary for the operator to provide tensile forces to the driving rod 12 with both hands simultaneously to avoid unilateral force on the connecting rod 8.
[0038] Furthermore, since the included angle between the vertical center line of the positioning rod 6 and the right inner wall of the support frame 1 is less than ninety degrees, therefore, affected by gravity, the positioning rod 6 has a tendency to move downward under normal conditions. Therefore, in order to prevent the winding roller 2 from being distorted due to the long-term downward pressure of the limiting roller 5 on the winding roller 2, a tension spring 9 is arranged on the side of the positioning rod 6 away from the winding roller 2 of this device. Each axial end of the tension spring 9 is constrained to be slidably connected to the adjacent positioning rod 6 and the support frame 1 respectively, and further constrained that when the tension spring 9 is not affected by external forces, the limiting roller 5 and the winding roller 2 are not in contact, thereby preventing the limiting roller 5 from pressing the winding roller 2 under normal conditions.
[0039] Furthermore, a push plate 3 is sleeved outside the winding roller 2 of this device. After the multi-layer aluminum-plastic film winding is completed, the wound aluminum-plastic film roll can be removed from the winding roller 2 by moving the push plate 3. This can further prevent the operator from directly intervening in the processing process and avoid the operator being injured due to misoperation.
[0040] Specifically, an internally threaded hole in the front-to-back axial direction is penetrated and opened at the lower end of the push plate 3, and a screw rod 11 is screwed in the internally threaded hole. Moreover, the screw rod 11 is rotatably connected to the support frame 1. By rotating the screw rod 11, the position of the push plate 3 can be changed by using the screwing relationship in the case where the push plate 3 cannot rotate relative to the screw rod 11.
[0041] Furthermore, an internally threaded hole is penetrated and opened on each of the left and right sides at the lower end of the push plate 3, and a screw rod 11 is screwed in each internally threaded hole. The push plate 3 can be restricted from rotating relative to a single screw rod 11 by the mutual restraint of the two screw rods 11.
[0042] Meanwhile, a driving motor II 16 is arranged between the two screw rods 11 of the device. The output shaft of the driving motor II 16 is in transmission connection with the two screw rods 11 through a gear set 10. This can achieve the rotation of the screw rods 11 and fully ensure the synchronous rotation of the two screw rods 11.
[0043] In the actual use process of the present utility model:
[0044] First of all, the operator inserts the end of the aluminum-plastic film into the through groove at the upper end of the winding roller 2 by surrounding the winding roller 2 from the lower part of the winding roller 2. At this time, the angle of the aluminum-plastic film covering the winding roller 2 is at least greater than 180°.
[0045] After that, the user holds the two grips 14 with both hands and pulls them to the right. At this time, the positioning rod 6 rotates counterclockwise, and the limiting roller 5 abuts against the aluminum-plastic film.
[0046] Then, the driving motor I 4 is turned on, and the winding roller 2 starts to rotate counterclockwise, and the aluminum-plastic film is wound layer by layer.
[0047] Finally, after the aluminum-plastic film roller is wound to an appropriate number of turns, the driving motor I 4 is turned off, and the driving motor II 16 is turned on. At this time, the push plate 3 pushes the aluminum-plastic film roller forward, and the aluminum-plastic film roller is separated from the winding roller 2 from the front side.
[0048] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
