Description

Technical Field

[0001] The utility model relates to the technical field of film tape processing, in particular to a film storage device and film tape conveying equipment. Background Art

[0002] The film strip conveying equipment generally includes a film releasing device, a film sealing and cutting device, and a bagging device. The film strip is released by the film releasing device, and the film strip is heat-sealed and cut by the film sealing and cutting device to form a film strip with one end closed and the other end open. Finally, the bagging device pulls the film strip into a square bag mouth for bagging. The film releasing device, the film sealing and cutting device, and the bagging device are generally produced together. Among them, since the film ring of the film releasing device continuously releases film, the film strip will gradually decrease, so the radius of the film ring gradually decreases, and then the length of the film strip continues to decrease. However, the length of the film strip used for bagging is consistent. In order to ensure that the length of the film strip released by the film releasing device is the same as the length of the film strip used for bagging, a film storage device is required to store the unrolled film strip. After the film storage device works for one round, the length of the film strip stored or output is consistent, which is not affected by the size of the film ring radius, thereby ensuring that the length of the film strip used by the subsequent film sealing and cutting device and the bagging device is consistent, and further making the length of the film strip used for each bagging the same.

[0003] In the related technology, the film storage device includes a frame, a film releasing mechanism, a floating frame, a floating film guide roller and a fixed film guide roller. The film releasing mechanism is arranged at the bottom of the frame, the film releasing mechanism is used to release the film, the floating frame slides up and down on the frame, the floating film guide roller rotates on the floating frame, the fixed film guide roller rotates on the upper end of the frame, the floating film guide roller is located between the film releasing mechanism and the fixed film guide roller, and the film strip released by the film releasing mechanism is sequentially wound around the floating film guide roller and the fixed film guide roller.

[0004] However, after the power of the film unwinding mechanism is cut off, the rotating shaft of the film unwinding mechanism will gradually stop. Since the rotating shaft only relies on the friction between the rotating shaft and the frame to stop, the rotating shaft decelerates slowly, causing the film unwinding mechanism to not stop rotating in time, and there is a risk of over-unwinding. When too much film is unwinded, the film belt will fall and rub against other parts, causing damage to the film belt.

[0005] Therefore, there is an urgent need to solve the problem of excessive film release by the film release mechanism. Utility Model Content

[0006] In order to solve the deficiencies of the prior art, the utility model provides a film storage device and a film tape conveying equipment, which avoids the problem of excessive film release due to the slow deceleration of the rotating shaft causing the film releasing mechanism to stop rotating in time, thereby avoiding the problem of excessive film release.

[0040] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. The described implementation is a part of the implementation of the utility model, not all of the implementations.

[0041] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1:

[0043] Please see attached Figure 1-3 The film storage device 10 of the present invention includes a fixing frame 100 , a film placing driving shaft 200 and a stop assembly 300 .

[0044] The fixing frame 100 is vertically set up and arranged adjacent to the film pulling device, so as to facilitate the film strip 211 to enter the film pulling device of the next station. The film releasing active shaft 200 is rotatably connected to the fixing frame 100, so that the film ring 210 on the film releasing active shaft 200 rotates relative to the fixing frame 100, thereby releasing the film strip 211. The stop assembly 300 includes an elastic member 310 and an abutment member 320. The elastic member 310 is a retractable elastic structure. One end of the elastic member 310 is connected to the fixing frame 100, and the other end of the elastic member 310 is connected to the abutment member 320. The elastic member 310 is used to apply elastic force to the abutment member 320, so that the abutment member 320 continuously abuts against the film releasing active shaft 200, that is, the elastic member 310 pushes the abutment member 320 to continuously abut against the film releasing active shaft 200.

[0045] In this embodiment, when the power of the film-releasing active shaft 200 is cut off, the film-releasing active shaft 200 will gradually stop rotating. Since the elastic member 310 pushes the abutting member 320 to continuously abut against the film-releasing active shaft 200, the film-releasing active shaft 200 is subjected to greater resistance, so that the film-releasing active shaft 200 stops rotating more quickly, and the film ring 210 stops rotating more quickly, thereby stopping the release of the film belt 211 in time. Preferably, the elastic member 310 can be a spring.

[0046] In the above-mentioned film storage device 10, after the film placing active shaft 200 stops rotating, the elastic member 310 pushes the abutting member 320 to continuously abut against the film placing active shaft 200. Therefore, compared with the conventional film placing active shaft 200, the film placing active shaft 200 of the present invention is subjected to greater rotational resistance, so that the film placing active shaft 200 can stop rotating in time, thus avoiding the problem of excessive film placing. Since the problem of excessive film placing is solved, the film belt 211 is prevented from sagging and being scratched, thereby avoiding the problem of the film belt 211 being damaged due to sagging.

[0047] In some preferred embodiments, the stop assembly 300 further includes a limiting column 330, a first end of which is fixedly connected to the fixing frame 100, and the abutment member 320 is sleeved on the limiting column 330, that is, a sleeve hole 321 is provided inside the abutment member 320, and the second end of the limiting column 330 is passed through the sleeve hole 321 and sleeved with the abutment member 320. The elastic member 310 is sleeved on the limiting column 330, and the two ends of the elastic member 310 are respectively abutted against the first end of the limiting column 330 and the abutment member 320, that is, the limiting column 330 is passed through the elastic member 310, one end of the elastic member 310 is connected to the first end of the limiting column 330, and the other end of the elastic member 310 is abutted against the abutment member 320. In this embodiment, the limiting column 330 is respectively disposed through the elastic member 310 and the abutting member 320 , so that the elastic member 310 abuts against the abutting member 320 more stably, thereby making the elastic force of the elastic member 310 acting on the abutting member 320 more stable.

[0048] In some preferred embodiments, the stop assembly 300 also includes a fixing member 340, which is fixedly connected to the fixing frame 100. The fixing member 340 is provided with a connecting hole 341. The second end of the limiting column 330 is passed through the connecting hole 341 and fixedly connected to the fixing member 340, so that the limiting column 330 is fixedly connected to the fixing frame 100 through the fixing member 340.

[0049] In some preferred embodiments, the stop assembly 300 also includes a blocking gasket 350, which is sleeved on the limiting column 330. The elastic member 310 abuts against the first end of the limiting column 330 through the blocking gasket 350, so that the blocking gasket 350 limits the position of the elastic member 310, so that the elastic member 310 can continue to elastically abut against the abutting member 320.

[0050] Preferably, the fixing member 340 is provided with an avoidance groove 342, and the film releasing active shaft 200 is passed through the avoidance groove 342, so that the film releasing active shaft 200 rotates in the avoidance groove 342, thereby reducing the distance between the fixing member 340 and the abutment member 320, and improving the structural compactness of the stop assembly 300.

[0051] In some more preferred embodiments, the abutment member 320 is provided with an arc-shaped abutment groove 322, the inner wall of which abuts against the film-releasing active shaft 200, so that the film-releasing active shaft 200 and the abutment member 320 fit more closely, thereby causing the film-releasing active shaft 200 to decelerate and stop rotating more quickly.

[0052] Embodiment 2:

[0053] The difference between this embodiment and embodiment 1 is that this embodiment further optimizes the structure of the membrane storage device 10 of the utility model, see Figure 2 .

[0054] The film storage device 10 further includes a fixed roller group 400 and a movable assembly 500. An active area 101 is formed between the fixed roller group 400 and the film placing active shaft 200. The fixed roller group 400 includes a film passing roller 410 and a lead-out roller 420. The number of the film passing rollers 410 is multiple, and the lead-out roller 420 and the multiple film passing rollers 410 are arranged in sequence. The movable assembly 500 is movably arranged in the active area 101. The movable assembly 500 includes a sliding member 510 and a film guide roller 520. The sliding member 510 is slidably connected to the fixed frame 100 up and down. The number of the film guide rollers 520 and the film passing rollers 410 is the same. The multiple film guide rollers 520 are arranged at intervals and rotatably connected to the sliding member 510. That is, the film placing active shaft 200, the movable assembly 500 and the fixed roller group 400 are sequentially established on the fixed frame 100 from bottom to top.

[0055] In this embodiment, the plurality of film-passing rollers 410 include a first film-passing member 410a and a second film-passing member 410b, and the film-guiding roller 520 includes a first film-guiding member 520a and a second film-guiding member 520b. The film-passing rollers 410 and the film-guiding rollers 520 are staggered. The film releasing active shaft 200 releases the film tape 211, and the film tape 211 is sequentially wound around the first film passing member 410a, the first film guiding member 520a, the second film passing member 410b and the second film guiding member 520b, and finally wound around the lead-out roller 420, and the film tape 211 is led out to the next workstation by the lead-out roller 420; when the film releasing active shaft 200 starts to rotate, thereby releasing the film tape 211, the movable component 500 slides downward under the action of gravity, and the first film passing member 410a, the first film guiding member 520a, the second film passing member 410b, the second film guiding member 520b and the lead-out roller 420 rotate simultaneously under the action of the film tape 211, thereby increasing the length of the film tape 211 in the active area 101 to achieve the effect of film storage. When the movable component 500 slides down to the lower limit position, the power of the film-releasing active shaft 200 is cut off, so that the film-releasing active shaft 200 gradually stops to complete the film storage; when the film-releasing active shaft 200 gradually stops, the film-pulling device of the next station starts to pull the film, so that the movable component 500 slides upward, and the lead-out roller 420, the second film guide member 520b, the second film passing member 410b, the first film guide member 520a and the first film passing member 410a rotate at the same time, so that the film storage device 10 outputs the film tape 211, and when the movable component 500 slides up to the upper limit position, the film pulling stops.

[0056] In some preferred embodiments, the movable assembly 500 further includes a counterweight 530, which is connected to the sliding member 510, that is, the counterweight 530 is disposed on the sliding member 510, so that the movable assembly 500 can slide down more smoothly during film storage to ensure normal film storage. Of course, the movable assembly 500 may not be provided with the counterweight 530, and in some other embodiments, the movable assembly 500 slides down on the fixed frame 100 by its own weight.

[0057] In some preferred embodiments, the film storage device 10 further includes an in-place sensor 600, which is mounted on the fixing frame 100. When the sliding member 510 moves to the lower limit position, the in-place sensor 600 is triggered, and the in-place sensor 600 is electrically connected to the control end of the driving member of the film placing active shaft 200. In this embodiment, when the sliding member 510 slides down to the limit position, the sliding member 510 triggers the in-place sensor 600, and the in-place sensor 600 transmits an in-place signal to the control end of the driving member, and the control end of the driving member cuts off the driving member.

[0058] It can be understood that the in-place sensor 600 can be a photoelectric sensor, a weight sensing sensor or other existing in-place sensors 600 .

[0059] In some more preferred embodiments, the film storage device 10 also includes a buffer member 700, which is installed on the fixed frame 100. The sliding member 510 elastically contacts the buffer member 700 when moving to the lower limit position, thereby preventing the movable component 500 from continuously sliding down to a position where it collides with the film ring 210 on the film release active shaft 200, thereby avoiding affecting the release of the film belt 211 by the film release active shaft 200.

[0060] Embodiment 3:

[0061] This embodiment provides a film tape conveying device based on the above embodiments.

[0062] A film tape conveying device includes a film pulling device (not shown in the figure) and a film storage device 10.

[0063] Among them, the film pulling device is arranged adjacent to the film storage device 10, and the film pulling device is used to pull out the film strip 211 in the film storage device 10. When the movable component 500 of the film storage device 10 slides down to the lower limit position, the film storage device 10 completes film storage. At this time, the film pulling device pulls out the film strip 211 stored in the film storage device 10. The tension generated by the film pulling device pulling the film drives the film strip 211 to move, thereby causing the movable component 500 to slide up to the upper limit position.
