TECHNICAL FIELD

[0001] The utility model belongs to composite packaging film roll technical field, specifically a kind of composite packaging film roll support. BACKGROUND

[0002] Composite packaging film refers to the packaging film formed by printing composite and other processes by multiple films, which is divided into aluminum-plastic composite packaging film and plastic composite packaging film according to material, and is divided into two layers, three layers, four layers, five layers and the like according to material structure. Composite film can make the packaging content have the characteristics of moisture retention, aroma retention, beauty, freshness preservation, light protection, permeation prevention, shelf life extension and wide application range.

[0003] The existing composite packaging film roll support usually has a tensioning structure inside, so that the composite packaging film is always kept tensioned during winding, thereby realizing better structural transmission effect and packaging film winding effect. The principle is usually to use a push rod to apply stress to the composite packaging film to make it displace to achieve tensioning purpose. The structure has high automation degree, but the design difficulty is high, and the matching degree of each component of the support is large. Therefore, the utility model provides a composite packaging film roll support. UTILITY MODEL CONTENT

This step realizes controllable spacing of the tensioning wheel and the driving roller by setting the tensioning frame and the load-bearing rod, thereby realizing tensioning of the composite packaging film, enhancing the practicability and applicability of the support, and being beneficial to solving the relaxation problem in the packaging film winding process, improving the film winding effect and the quality of finished products.

[0006] Preferably, a first lifting rod is rotatably connected to the bottom of the film rolling platform, and two first lifting rods are arranged correspondingly. A second slider is rotatably connected to the ends of the two first lifting rods. A second lifting rod is rotatably connected to the sidewalls of the two first lifting rods, and two second lifting rods are arranged correspondingly. A first slider is rotatably connected to the sidewall of the second lifting rod. A first fixing rod is slidably connected to the inner sidewall of the first slider, and the first fixing rod is fixed to the sidewall of the film rolling platform. A second fixing rod is slidably connected to the corresponding sidewall of the second slider, and a base is fixed to the end of the second fixing rod. A fixed platform is fixed to the top of the base, and a threaded rod is rotatably connected between the fixed platform and the base. This step, by setting the first lifting rod and the second lifting rod in conjunction with their connected components to adjust the height of the bracket, and by setting the threaded rod and the second slider to control the movement of the first lifting rod and the second lifting rod, realizes the convenient adjustment of the height of the composite packaging film roll bracket, enhancing the flexibility and applicability of the bracket.

A slot for inserting a card is provided at the top of the rotating rod. A first limiting hole and a second limiting hole are provided on the side wall of the film winding table, and a limiting block is provided inside the first limiting hole and the second limiting hole. This step limits the position of the rotating rod by setting the limiting block, the first limiting hole, and the second limiting hole, thereby preventing the rotating rod from rebounding and preventing the tension frame and the tension frame connected components from continuously applying tension to the return spring when the bracket is restricted. This improves the practicality and convenience of the bracket and helps to extend the service life of the bracket.

[0008] Preferably, a first stop is fixedly connected to the side wall of the limiting block, and two first stops are arranged in a corresponding manner. A second stop is fixedly connected to the side wall of the limiting block. This step restricts the limiting block to a predetermined position on the film winding table by setting the first stop and the second stop, thereby preventing the limiting block from falling off or being lost, and improving the practicality and convenience of the bracket.

[0009] Preferably, load-bearing blocks are fixed to both ends of the load-bearing rod, and the two load-bearing blocks are positioned corresponding to the position of the rotating rod. This step increases the contact area between components by setting load-bearing blocks, thereby reducing pressure, which helps to extend the service life of the bracket and reduce maintenance requirements.

[0010] Preferably, a handle is fixed to the side wall of the rotating rod, and an anti-slip sleeve is provided on the side wall of the handle.

[0011] Preferably, a handle is fixed to the end of the threaded rod, and the handle is set to correspond to the size of the base. This step increases the torque by setting the handle to control the threaded rod, which provides convenience for the daily use of the staff and enhances the practicality of the bracket.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The composite packaging film roll support described in this utility model achieves controllable spacing between the tensioning wheel and the drive roller by setting a tensioning frame and a support rod, thereby realizing the tensioning of the composite packaging film, enhancing the practicality and applicability of the support, helping to solve the problem of slack in the packaging film rolling process, and improving the film rolling effect and finished product quality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] like Figures 1 to 3 As shown, a composite packaging film roll support according to an embodiment of the present invention includes a film rolling platform 1. A tensioning frame 3 is rotatably connected inside the film rolling platform 1. Fixed protrusions 2 are fixedly connected to the inner side wall of the film rolling platform 1, and two fixed protrusions 2 are arranged correspondingly. A drive roller 7 is rotatably connected between the two fixed protrusions 2, and two drive rollers 7 are arranged correspondingly. Tensioning wheels 4 are rotatably connected between corresponding side walls of the tensioning frame 3, and multiple tensioning wheels 4 are arranged correspondingly. Second transmission gears 9 are fixedly connected to the ends of the two drive rollers 7 respectively. The two second transmission gears 9 mesh with the first transmission gear 8. A support rod 5 is fixedly connected to the end of the tensioning frame 3. An arc groove is provided on the side wall of the film roll table 1, and the arc groove is set to correspond to the size of the support rod 5. A return spring 10 is fixedly connected between the tensioning frame 3 and the fixed protrusion 2, and the two return springs 10 are set in a corresponding manner. During operation, the operator can adjust the position of the support rod 5 to achieve the tensioning function of the film roll support. During the process, whenever the support rod 5 fixed to the end of the tensioning frame 3 moves, the support rod 5 will be released. When the force bar 5 moves within the arc groove, the tension frame 3 and the multiple tensioning wheels 4 rotatably connected to the tension frame 3 will rotate together with the tension frame 3. Since the composite packaging film is in contact with the surfaces of multiple active rollers 7 and multiple tensioning wheels 4 at the same time, the distance between the multiple tensioning wheels 4 and multiple active rollers 7 will increase as the tension frame 3 rotates. As this distance increases, the composite film will be tightened. The second transmission gear 9 fixed to the side wall of the active roller 7 and the first transmission gear 8 rotatably connected to the side wall of the film rolling table 1 play a transmission role. The two corresponding fixed protrusions 2 play a role in fixing the active roller 7. The return spring 10 fixed between the fixed protrusion 2 and the tension frame 3 plays a role in resetting the tension frame 3. This step achieves controllable spacing between the tensioning wheels 4 and the active rollers 7 by setting the tension frame 3 and the force bar 5, thereby achieving tension of the composite packaging film, enhancing the practicality and applicability of the bracket, helping to solve the problem of slack in the film rolling process, and improving the film rolling effect and finished product quality.

[0024] like Figure 1 and Figure 4As shown, a first lifting rod 17 is rotatably connected to the bottom of the film winding table 1, and two first lifting rods 17 are arranged correspondingly. A second slider 22 is rotatably connected to the ends of the two first lifting rods 17. A second lifting rod 18 is rotatably connected to the side walls of the two first lifting rods 17, and the two second lifting rods 18 are arranged correspondingly. A first slider 19 is rotatably connected to the side wall of the second lifting rod 18. A first fixing rod 20 is slidably connected to the inner side wall of the first slider 19, and the first fixing rod 20 is fixed to the side wall of the film winding table 1. A second fixing rod 21 is slidably connected to the corresponding side wall of the second slider 22, and a base 26 is fixed to the end of the second fixing rod 21. A fixing platform 23 is fixed to the top of the base 26, and a threaded rod 24 is rotatably connected between the fixing platform 23 and the base 26. During operation, the threaded rod 24 rotatably connected between the fixing platform 23 and the base 26 is threadedly connected to the second slider 22. The operator can rotate the threaded rod 24 to achieve this connection. The height of the bracket is controlled by the threaded rod 24. During the process, when the threaded rod 24 rotates, the second slider 22, which is threadedly connected to the threaded rod 24, is simultaneously restricted by the two second fixed rods 21, thus moving horizontally at the top of the base 26. Accompanying the movement of the second slider 22, multiple first lifting rods 17 and multiple second lifting rods 18 will rotate through their corresponding rotational connections, ultimately allowing the film roll platform 1 and the base 26 to move closer and further apart. The first slider 19 and the first fixed rod 20 guide the second lifting rods 18. This step adjusts the height of the bracket by setting the first lifting rods 17 and second lifting rods 18 in conjunction with their connected components. By setting the threaded rod 24 and the second slider 22 to control the movement of the first lifting rods 17 and second lifting rods 18, the height adjustment of the composite packaging film roll bracket is made convenient, enhancing the flexibility and applicability of the bracket.

[0025] like Figure 1 and Figure 2As shown, a rotating rod 11 is rotatably connected to the side wall of the film rolling table 1, and the rotating rod 11 is positioned corresponding to the bearing rod 5. A slot for inserting a card is provided at the top of the rotating rod 11. A first limiting hole 12 and a second limiting hole 13 are provided on the side wall of the film rolling table 1, and limiting blocks 14 are provided inside the first limiting hole 12 and the second limiting hole 13. During operation, the operator can rotate the rotating rod 11 to make it contact the bearing rod 5, thereby adjusting the angle of the tension frame 3. The operator can fix the position of the rotating rod 11 by inserting the limiting block 14 into the first limiting hole 12 and the second limiting hole 13. When the bracket is in the packaging film tensioned state, the operator can... The limiting block 14 is inserted into the first limiting hole 12 and positioned at the top of the rotating rod 11. Whenever the bracket is idle, the operator can insert the limiting block 14 into the second limiting hole 13 and position it at the bottom of the rotating rod 11. The slot at the top of the rotating rod 11 corresponds to the size of the limiting block 14. This step limits the position of the rotating rod 11 by setting the limiting block 14, the first limiting hole 12, and the second limiting hole 13, thereby preventing the rotating rod 11 from rebounding and preventing the tension frame 3 and the connected components of the tension frame 3 from continuously applying tension to the return spring 10 when the bracket is restricted. This improves the practicality and convenience of the bracket and helps to extend the service life of the bracket.

[0026] like Figure 2 As shown, a first stop 15 is fixedly connected to the side wall of the limiting block 14, and the two first stop 15s are arranged correspondingly. A second stop 16 is fixedly connected to the side wall of the limiting block 14. During operation, the two first stop 15s fixed to the side wall of the limiting block 14 can cooperate with the second stop 16 to restrict the limiting block 14 to the predetermined position of the film winding table 1, preventing the limiting block 14 from falling off. This step restricts the limiting block 14 to the predetermined position of the film winding table 1 by setting the first stop 15 and the second stop 16, thereby preventing the limiting block 14 from falling off or being lost, and improving the practicality and convenience of the bracket.

[0027] like Figure 2 As shown, load-bearing blocks 6 are fixed to both ends of the load-bearing rod 5, and the two load-bearing blocks 6 are set at the positions corresponding to the rotating rod 11. During operation, whenever the operator rotates the rotating rod 11, the bottom of the rotating rod 11 will contact the load-bearing blocks 6 fixed to both ends of the load-bearing rod 5, thereby adjusting the position of the tensioning frame 3. This step increases the contact area between components by setting load-bearing blocks 6, thereby reducing pressure, which is beneficial to extending the service life of the bracket and reducing maintenance requirements.

[0028] like Figure 2As shown, a handle 27 is fixedly connected to the side wall of the rotating rod 11, and an anti-slip sleeve 28 is provided on the side wall of the handle 27. During operation, the operator can rotate the rotating rod 11 by means of the handle 27 fixed to the side wall of the rotating rod 11. The anti-slip sleeve 28 provided on the side wall of the handle 27 plays the role of preventing slippage and protecting the hand. This step provides convenience for the daily use of the operator by setting the handle 27, and reduces safety hazards by setting the anti-slip sleeve 28, thereby enhancing the practicality of the device.

[0029] like Figure 4 As shown, a handle 25 is fixed to the end of the threaded rod 24, and the handle 25 is set to correspond to the size of the base 26. During operation, the handle 25, which is set to correspond to the size of the base 26, can rotate in its own position. The operator can use the handle 25 to rotate the threaded rod 24. This step increases the torque by setting the handle 25 to control the threaded rod 24, which provides convenience for the operator's daily use and enhances the practicality of the bracket.

[0030] During operation, the operator can adjust the position of the support rod 5 to achieve the tensioning function of the film roll support. During this process, whenever the support rod 5 fixed to the end of the tensioning frame 3 moves—that is, when the support rod 5 moves within the arc groove—the tensioning frame 3 and the multiple tensioning wheels 4 rotatably connected to it will rotate together. Since the composite packaging film simultaneously contacts the surfaces of multiple drive rollers 7 and multiple tensioning wheels 4, the distance between the multiple tensioning wheels 4 and the multiple drive rollers 7 will increase with the rotation of the tensioning frame 3. As this distance increases, the composite film will be tightened. The second transmission gear 9 fixed to the side wall of the drive roller 7 and the first transmission gear 8 rotatably connected to the side wall of the film roll table 1 provide the transmission function. The fixed protrusion 2 serves to fix the active roller 7, and the return spring 10, fixed between the fixed protrusion 2 and the tension frame 3, serves to reset the tension frame 3. The threaded rod 24, which is rotatably connected between the fixed platform 23 and the base 26, is threadedly connected to the second slider 22. The operator can control the height of the bracket by rotating the threaded rod 24. During the process, when the threaded rod 24 rotates, the second slider 22, which is threadedly connected to the threaded rod 24, is simultaneously restricted by two second fixed rods 21, thus moving horizontally at the top of the base 26. Accompanying the movement of the second slider 22, multiple first lifting rods 17 and multiple second lifting rods 18 will rotate through their corresponding rotatable connections, ultimately achieving... The film rolling platform 1 and the base 26 move closer and further apart. The first slider 19 and the first fixing rod 20 guide the second lifting rod 18. The operator can rotate the rotating rod 11 to contact the load-bearing rod 5, thereby adjusting the angle of the tension frame 3. The operator can fix the position of the rotating rod 11 by inserting the limiting block 14 into the first limiting hole 12 and the second limiting hole 13. When the bracket is in the packaging film tensioned state, the operator can insert the limiting block 14 into the first limiting hole 12, placing the limiting block 14 at the top of the rotating rod 11. Whenever the bracket is in an idle state, the operator can insert the limiting block 14 into the second limiting hole 13, placing the limiting block 14 at the bottom of the rotating rod 11. The rotating rod... The card slot at the top of the 11 corresponds to the size of the limiting block 14. The two first blocks 15 fixed to the side wall of the limiting block 14 can cooperate with the second block 16 to restrict the limiting block 14 to the predetermined position of the film rolling table 1 and prevent the limiting block 14 from falling off. Whenever the operator rotates the rotating rod 11, the bottom of the rotating rod 11 will contact the bearing blocks 6 fixed to both ends of the bearing rod 5, thereby adjusting the position of the tensioning frame 3. The operator can rotate the rotating rod 11 by means of the handle 27 fixed to the side wall of the rotating rod 11. The anti-slip sleeve 28 set on the side wall of the handle 27 plays the role of anti-slip and protecting the hand. The rotating handle 25, which corresponds to the size of the base 26, can rotate in its own position. The operator can rotate the threaded rod 24 by means of the rotating handle 25.
