Description

Technical Field

[0001] The utility model relates to the technical field of winding mechanisms, in particular to an aluminum-plastic film winding mechanism with high automation degree. Background Technique

[0002] The aluminum-plastic film is a film structure with a thin aluminum layer covered on the surface layer, which has good ductility and excellent heat insulation performance. Therefore, some of its application scenarios are external covering heat insulation materials, such as: the inner lining of takeout boxes, food packaging bags, etc.

[0003] During the production process of the aluminum-plastic film, multiple processes are required, and it is often necessary to transfer between different processes. For the convenience of transfer, the aluminum-plastic film often needs to be wound to reduce the occupied space area and facilitate the subsequent steps. Among them, the base film of the aluminum-plastic film, that is, the film structure only including the base material and the thin aluminum layer, generally requires the assistance of an inner core roller during the winding process, and the aluminum-plastic film is wound around the outer side of the inner core roller.

[0004] In the prior art devices, since rotation and limit need to be completed synchronously, generally, a support tube is fixedly connected to the output shaft of the driving motor, and a corresponding clamping mechanism is arranged on the side end of the support tube, and the clamping mechanism is used to realize the synchronous movement between the support tube and the inner core roller.

[0005] However, the method of clamping and fixing generally affects the winding process, and its single size is generally small, which makes the diameter change range of the inner core roller that can be clamped and fixed small. At the same time, the existence of the clamping mechanism also makes the operator need to perform more operation procedures to avoid the force imbalance of the inner core roller during rotation. Therefore, we believe that an aluminum-plastic film winding mechanism with simple operation and wide application range 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 with high automation degree, which has the advantages of simple operation and wide application range, and solves the disadvantages of many operation procedures and small adjustable range of the prior art devices.

[0007] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0008] An aluminum-plastic film winding mechanism with high automation degree, including a support tube in the front-back axial direction, an inner core roller coaxially sleeved outside the support tube. A screw rod is coaxially and rotatably connected inside the support tube. One axial end of the screw rod is key-connected with a driving motor, and the driving motor is fixedly connected with the support tube. Moreover, one axial end of the support tube is fixedly connected with a driving bracket. A plurality of driving parts are coaxially sleeved on the outside of the screw rod in parallel from front to back. The driving parts are screwed with the screw rod. A driving groove is circumferentially penetrated through the side end of each driving part. Moreover, the distances between the front and rear ends of each driving groove and the central axis of the driving part are not equal. A driven rod with a central axis perpendicular to the central axis of the driving part is arranged at the upper end of each driving groove. An installation hole is penetrated through the support tube for the driven rod. The driven rod is inserted into the installation hole, and the end of the driven rod far from the driving part protrudes outside the support tube. The inner side wall of the inner core roller abuts against the driven rod.

[0009] Preferably, a U-shaped frame with a U-shaped opening facing the driving part is fixedly connected to one end of each driven rod close to the driving part. A bearing is rotatably connected inside the U-shaped opening of the U-shaped frame, and the bearing is embedded in the driving groove and abuts against the driving part.

[0010] Preferably, an installation plate with an arc-shaped structure in the vertical plane projection is fixedly connected to the end of the driven rod far from the driving part, and a damping pad is fixedly connected to the outside of the installation plate.

[0011] Preferably, through holes are penetrated through the installation plate and the damping pad. Bolts are inserted into the through holes, and each bolt is threadedly connected with the corresponding driven rod.

[0012] Preferably, limiting parts are respectively fixedly connected to the upper and lower sides of one end of the driving bracket close to the support tube. Installation grooves are opened for the driving motor at the close ends of the two limiting parts. The upper and lower sides of the middle section of the driving motor are respectively embedded in the installation grooves.

[0013] Preferably, an auxiliary tube with a T-shaped structure in the vertical plane is inserted into the installation hole. The driven rod is inserted into the auxiliary tube, and the larger-width part of the driven rod is located outside the support tube and fixedly connected with the outer side wall of the support tube.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] By moving the driving part, the distance between the driven rod and the central axis of the support tube can be changed, so as to realize the tightening and fixing of the inner core roller. This not only has a wider adaptation range, but also can realize the automatic positioning effect of the inner core roller, ensuring that the inner core roller is coaxial with the support tube.

[0016] The present utility model drives the screw rod to rotate through the driving motor, so as to realize the forward and backward movement of the driving part. This makes it only necessary for the operator to complete the process of taking and placing the inner core roller during the actual operation to complete the overall winding. This can effectively reduce the operation steps and relieve the burden of the operator. Brief Description of the Drawings

Detailed Description of the Preferred Embodiments

[0025] 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 of 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.

[0026] 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 thus should not be construed as a limitation to the present utility model.

[0027] Please refer to Figure 1-7, An aluminum-plastic film winding mechanism with a high degree of automation, which is consistent with the prior art device. This device includes a support tube 2, and the inner core roller 1 used in winding is supported by the support tube 2.

[0028] Different from the prior art device, this device is provided with a plurality of mounting holes on the support tube 2 whose central axes are perpendicular to the central axis of the support tube 2. A driven rod 12 is coaxially inserted into the mounting holes. Therefore, by sliding the driven rod 12, the distance between the driven rod 12 and the central axis of the support tube 2, that is, the distance between the driven rod 12 and the inner side wall of the inner core roller 1 can be changed. This can use the driven rod 12 to support and limit the inner core roller 1, ensuring that the inner core roller 1 can always be coaxial with the support tube 2 during the actual winding process.

[0029] Furthermore, this device is fixedly connected with a mounting plate 11 whose vertical plane projection is an arc structure at one end of the driven rod 12 away from the driving part 8. By means of the mounting plate 11, the contact area between this device and the inner core roller 1 is increased, the local pressure is reduced, and it is avoided that the pressure exerted by the driven rod 12 on the inner core roller 1 is too large, resulting in damage and deformation of the inner core roller 1.

[0030] Furthermore, this device is fixedly connected with a damping pad 9 on the outside of the mounting plate 11. The damping pad 9 can be made of rubber material. This can increase the frictional resistance between this device and the inner core roller 1. Cooperating with the tightening effect of the driven rod 12 on the inner core roller 1, it can fully ensure that the inner core roller 1 can be driven to achieve synchronous rotation effect during the rotation of the support tube 2, realizing the winding process of the aluminum-plastic film.

[0031] Furthermore, for the convenience of assembly, this device is provided with through holes on the mounting plate 11 and the damping pad 9. Bolts 10 are inserted into the through holes, and each bolt 10 is threadedly connected to the corresponding driven rod 12.

[0032] Furthermore, in order to improve the constraint effect on the driven rod 12, this device inserts an auxiliary tube 5 whose vertical plane projection is a T-shaped structure into each mounting hole, and the driven rod 12 is constrained to be inserted into the auxiliary tube 5 to increase the constraint area of the driven rod 12.

[0033] It should be noted that as shown in the figure, the wider part of the auxiliary tube 5 is located outside the support tube 2 and is fixedly connected to the support tube 2, which can be realized by welding in practice.

[0034] Specifically, in order to adjust the position of the driven rod 12, this device is provided with a driving part 8 between a plurality of driven rods 12 in the same vertical plane, and driving grooves 15 are provided on the outer side of the driving part 8 for the corresponding plurality of driven rods 12 to penetrate through.

[0035] Therefore, the distances between the front and rear ends of the constraint drive slot 15 and the central axis of the drive member 8 are not equal. Thus, by changing the contact position between the driven rod 12 and the drive slot 15, the distance between the central axis of the driven rod 12 and the support tube 2 can be changed.

[0036] Furthermore, at one end of each driven rod 12 close to the drive member 8, a U-shaped frame 13 with a U-shaped opening facing the drive member 8 is fixedly connected. A bearing 14 is rotatably connected within the U-shaped opening of the U-shaped frame 13. Therefore, when the constraint bearing 14 is inserted into the drive slot 15 and abuts against the drive member 8, the relative sliding between the driven rod 12 and the drive member 8 can be avoided by utilizing the characteristics of the bearing 14, thereby reducing friction and loss.

[0037] Specifically, to change the position of the drive member 8, a screw rod 3 is coaxially and fixedly connected inside the support tube 2 of the device, and a drive motor 7 is key-connected to one axial end of the screw rod 3. By constraining the drive motor 7 to be fixedly connected to the support tube 2, the self-rotation of the screw rod 3 can be achieved.

[0038] Therefore, an internal threaded hole is penetrated through the drive member 8 of the device. By constraining the drive member 8 to be sleeved outside the screw rod 3 and screwed to the screw rod 3, the front and rear positions of the drive member 8 can be changed by rotating the screw rod 3 on the premise that the bearing 14 forms a position constraint on the drive member 8.

[0039] Specifically, to rotate the support tube 2, a drive bracket 4 is fixedly connected to one axial end of the support tube 2. When the drive bracket 4 rotates, the support tube 2 can be driven to rotate. In practice, the drive bracket 4 is connected to a servo motor.

[0040] Furthermore, to facilitate the wiring harness erection and the separation of the inner core roller 1 from the support tube 2, the device constrains the drive bracket 4 and the drive motor 7 to be on the same side of the support tube 2.

[0041] Therefore, at the upper and lower sides of one end of the drive bracket 4 close to the support tube 2, limit members 6 are respectively fixedly connected. Installation slots are provided at the ends of the two limit members 6 facing the drive motor 7. By respectively inserting the upper and lower sides of the middle section of the drive motor 7 into the installation slots, the fixed connection among the drive motor 7, the drive bracket 4, and the support tube 2 can be achieved.

[0042] In the actual use process of the present utility model:

[0043] First, the operator inserts the inner core roller 1 into the outside of the support tube 2 from the front side of the support tube 2;

[0044] Then, the drive motor 7 is started, the screw rod 3 rotates, and the drive member 8 moves from front to back. At this time, the driven rod 12 moves in a direction away from the screw rod 3. Multiple driven rods 12 simultaneously apply a thrust to the inner core roller 1 in a direction away from the support tube 2, so that the inner core roller 1 is coaxial with the support tube 2;

[0045] After that, cover the aluminum-plastic film on the side end of the inner core roller 1 to complete the fixation, and start the driving structure corresponding to the driving bracket 4. The driving bracket 4 drives the support tube 2 to rotate at a high speed to realize the winding process of the aluminum-plastic film;

[0046] Finally, when the winding reaches an appropriate thickness, stop the driving structure corresponding to the driving bracket 4, start the driving motor 7 in reverse, cancel the pressing effect on the inner core roller 1, and the operator removes the inner core roller 1 from the support tube 2.

[0047] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
