Description

Technical Field

[0001] The utility model belongs to the technical field of automation equipment, in particular to an auxiliary winding mechanism for a film supply machine. Background Art

[0002] In production operations, it is often necessary to attach protective films to the surfaces of small parts, and film supply machines are important equipment for realizing automatic film application. Although there are many film supply machines on the market, most of them have a defect during use: when the discarded film tape is recycled, it is easy to roll back and squeeze the normal film tape at the loading station, causing the protective film on the normal film tape to shift in position or be directly folded and damaged.

[0003] To solve this problem, the utility model patent with application number 2018212017350 proposes a glue film supply machine, which increases the friction on the waste film tape by setting a pressure roller that cooperates with the first pulling roller to ensure that the waste film tape can be transported stably; however, since the spacing between the pressure roller and the first pulling roller is fixed, only waste film tapes of corresponding thickness specifications can pass through. If there are still some protective film sheets left on the waste film tape, the thickness will increase to form an obstacle, resulting in the waste film tape being unable to pass normally and piling up, causing great trouble to users.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments of the present application, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the protection scope of the present application. It is understood that the drawings are only provided for reference and illustration, and are not used to limit the present application. The connection relationship shown in the drawings is only for the convenience of clear description and does not limit the connection method.

[0030] See attached Figure 1 -Attached Fig. 9An auxiliary winding mechanism for a film supply machine is installed on a film supply machine body 1 and includes a carrier 2, a fixed frame 3 and an elastic member 4; the film supply machine body 1 is provided with a feed roller 11, a winding roller 12, and a driving unit 13 for driving the feed roller 11 and the winding roller 12 to rotate synchronously; the carrier 2 is installed on the film supply machine body 1 and is located beside the feed roller 11; a pressing roller 31 is rotatably installed on the fixed frame 3, and a guide rod 32 slidably connected to the carrier 2 is provided on the fixed frame 3, so that the pressing roller 31 can be away from the feed roller 11; the two ends of the elastic member 4 are respectively abutted against the carrier 2 and the fixed frame 3, and when the pressing roller 31 is away from the feed roller 11, the elastic member 4 deforms and stores energy.

[0031] For ease of understanding, the present invention is described in conjunction with various parts of the film supply machine body 1, as follows:

[0032] When in use, the film tape roll is installed on the receiving wheel 15 of the film supply machine body 1, and the film tape is pulled out and passed through the loading station and the feed roller 11 in sequence, and is fixed on the winding roller 12, and then the driving unit 13 is started to drive the feed roller 11 and the winding roller 12 to rotate synchronously, so that the film tape can be driven to move, so as to transfer the protective film sheet to the loading station for use, while the winding roller 12 simultaneously winds up the waste film tape m.

[0033] In the process of winding up the waste film tape m, the pressure roller 31 squeezes the waste film tape m under the action of the elastic member 4 to ensure the stable movement of the waste film tape m by increasing the friction force. If there is a missed protective film sheet on the waste film tape m, the protective film sheet will exert pressure on the pressure roller 31 when passing through the feed roller 11, so that the pressure roller 31 moves to avoid the position and provide a passage space to ensure that the protective film sheet can pass smoothly. After the protective film sheet passes smoothly, the elastic member 4 that has deformed and stored energy returns to its original state to drive the pressure roller 31 to reset, so as to increase the friction force on the waste film tape m again.

[0034] In summary, the utility model designs a pressure roller 31 to be used in conjunction with the feed roller 11 to increase the friction force on the waste film tape m, thereby ensuring that the waste film tape m can move stably; and because the fixed frame 3 on which the pressure roller 31 is installed is slidably connected to the carrier 2, the pressure roller 31 is used in conjunction with the elastic member 4 to have an avoidance function, thereby ensuring that the missed protective film sheet can also smoothly pass through the gap between the pressure roller 31 and the feed roller 11, thereby solving the problem that the waste film tape m is easily retained and accumulated.

[0035] See attached Figure 1 -Attached Fig. 9 The elastic member 4 can be made of materials such as a spring, a rubber block 520, etc., and can be installed in various ways, which is not limited in the present invention. In order to improve installation convenience and control manufacturing cost, in the present invention, the elastic member 4 is a spring, which is sleeved on the guide rod 32, and its two ends respectively abut against the carrier 2 and the fixed frame 3.

[0036] Specifically, when the waste film strip m with the protective film passes through the feed roller 11, the protective film will drive the pressure roller 31 to move inward, causing the spring to compress and store energy; after the protective film passes smoothly, the spring releases energy and recovers, driving the pressure roller 31 to return to its original position and contact the waste film again.

[0037] See attached Figure 1 -Attached Fig. 9 The utility model also includes an adjusting part 5, which includes a connecting block 51 and an adjusting bolt 52. The tail end of the guide rod 32 is away from the fixed frame 3 and can slidably pass through the carrier 2; the connecting block 51 is installed at the tail end of the guide rod 32, one end of the adjusting bolt 52 is threadedly connected to the connecting block 51, and the other end of the adjusting bolt 52 abuts against the carrier 2.

[0038] Specifically, when the elastic member 4 is in an undeformed state, the distance between the nip roller 31 and the feed roller 11 is the smallest, and only a film strip of a specific thickness can be fed at this time;

[0039] When it is necessary to adapt to film tapes of other thicknesses, rotate the adjusting bolt 52 to increase the protruding length of the adjusting bolt 52. During this process, the fixing frame 3 will gradually approach the carrier 2 and squeeze the elastic member 4, thereby increasing the distance between the pressure roller 31 and the feed roller 11, thereby being able to adapt to film tapes of other thicknesses. Therefore, the design of the adjusting portion 5 can adjust the relative positions of the pressure roller 31 and the feed roller 11 to improve adaptability.

[0040] See attached Figure 1 -Attached Fig. 9 A rubber block 520 is installed on one end of the adjusting bolt 52 that contacts the carrier 2; the design of the rubber block 520 can avoid rigid collision between the adjusting bolt 52 and the carrier 2, thereby extending the service life of both.

[0041] See attached Figure 1 -Attached Fig. 9 The utility model also includes a driving unit 6. The carrier 2 is slidably mounted on the film supply machine body 1. The driving unit 6 is mounted on the film supply machine body 1 and is drivingly connected to the carrier 2 to drive the carrier 2 to move toward the feed roller 11.

[0042] According to different usage conditions, the driving part 6 has two embodiments: one is used alone and the other is used in conjunction with the adjusting part 5. The details are as follows:

[0043] Embodiment 1

[0044] The driving part 6 is used alone; during use, if the adjusting part 5 is not provided, the driving part 6 can be used to drive the carrier 2 to move toward the feed roller 11, thereby making the pressing roller 31 move away from or close to the feed roller 11 to adjust the distance between the pressing roller 31 and the feed roller 11; and since the adjusting part 5 is not provided, the elastic member 4 will not be squeezed to change the elastic potential energy of the elastic member 4, thereby avoiding excessive pressure on the pressing roller 31 due to excessive elastic potential energy of the elastic member 4, causing the pressing roller 31 to completely press the film tape onto the feed tape.

[0045] Embodiment 2

[0046] It is used in conjunction with the adjusting part 5. During use, if the elastic potential energy of the elastic part 4 is too large, the pressure roller 31 will be driven to tightly squeeze and fit the feed roller 11, resulting in the film tape being unable to pass smoothly. However, if the elastic potential energy of the elastic part 4 is too small, it will not be able to increase the friction force on the discarded film. If the adjusting part 5 and the driving part 6 are provided at the same time, the adjusting part 5 can be used as a component for adjusting the elastic part 4.

[0047] Specifically, when in use, the elastic potential energy of the elastic member 4 is first adjusted through the adjustment part 5, and then the thickness of the waste film is measured, and the position of the carrier 2 is adjusted through the driving part 6, and then the distance between the pressing roller 31 and the feeding roller 11 is adjusted; therefore, the coordinated use of the adjustment part 5 and the driving part 6 can not only improve the adaptability to adapt to film tapes of different thickness specifications, but also make the pressing roller 31 accurately fit the waste film tape m.

[0048] It should be noted that, compared with the first embodiment, the second embodiment has better advantages, so the second embodiment is actually preferred as the main implementation scheme.

[0049] See attached Figure 1 -Attached Fig. 9 There are various types of driving parts 6, for example, a screw motor with a stroke can be used, and for the convenience of operation, the driving part 6 in this embodiment includes a slider 61 and a driving bolt 62, and a slide groove 14 is provided on the film supply machine body 1, the slider 61 is arranged on the carrier 2 and is slidably connected to the slide groove 14, the driving bolt 62 is rotatably installed on the film supply machine body 1, and one end of the driving bolt 62 extends into the slide groove 14 and is threadedly connected to the slider 61.

[0050] Specifically, the slider 61 can be driven to move along the slide groove 14 by rotating the driving bolt 62 , thereby driving the carrier 2 , so that the pressing roller 31 moves away from or close to the feeding roller 11 .

[0051] See attached Figure 1 -Attached Fig. 9The utility model also includes a pressure fork 7, and a pressure groove 121 is provided on the winding roller 12; the pressure fork 7 is slidably installed on the winding roller 12, and has a first position for engaging with the pressure groove 121 and a second position for disengaging from the pressure groove 121.

[0052] Specifically, before use, the pressure fork 7 is in the second position, the end of the waste film tape m is placed in the pressure groove 121, and the pressure fork 7 is adjusted from the second position to the first position, so that the waste film tape m can be pressed tightly in the pressure groove 121, and the end of the waste film tape m is fixed on the winding roller 12. At this time, the winding roller 12 is driven to rotate by the driving member to reel in the waste film tape m.

[0053] After the waste film tape m is completely rolled up, the pressure fork 7 is switched from the first position to the second position, so that the waste film tape m can be released from the winding roller 12, making it convenient for the user to remove the waste film tape m in a unified manner.

[0054] Therefore, the combined use of the pressing fork 7 and the pressing groove 121 can, on the one hand, fix the discarded film tape m, and on the other hand, facilitate the user to remove the film tape from the roller 12, thereby improving the convenience of use.

[0055] See attached Figure 1 -Attached Fig. 9 The roller 12 is also provided with an insertion hole 122, the pressure fork 7 is U-shaped, and one end of the pressure fork 7 can be slidably installed in the insertion hole 122, and the other end of the pressure fork 7 can be switched between the first position and the second position.

[0056] Specifically, when in use, the pressure fork 7 is slid outward along the direction of the insertion hole 122 to drive the pressure fork 7 to move from the first position to the second position, so that the pressure fork 7 is completely separated from the roller 12; similarly, the pressure fork 7 is slid inward along the direction of the insertion hole 122 to drive the pressure fork 7 to move from the second position to the first position, so that the pressure fork 7 is installed on the roller 12.

[0057] It should also be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
