DETAILED DESCRIPTION

[0030] The two embodiments of the application will be described in detail below with reference to the drawings.

[0031] First embodiment:

[0032] Figures 1-2 A self-adhesive film feeding device is shown, wherein a represents a film material and b represents a film piece. The device comprises a bottom plate 1 integrated with a control chip. The upper end of the bottom plate 1 is fixedly connected with a feeding frame 2. The left top and bottom of the feeding frame 2 are respectively provided with a feeding roller 31 and a collecting roller 32. The middle part of the feeding frame 2 is fixedly connected with a bearing platform 72. The side wall of the feeding frame 2 is fixedly connected with a crossbar. The lower end of the crossbar is provided with a pressure plate 71 through a gas cylinder. The pressure plate 71 is located directly above the bearing platform 72. The right end of the feeding frame 2 is connected with a film dividing platform 4 through two electric sliding tables. The electric sliding table is driven by a servo motor on the side of the feeding frame 2, so that the film dividing platform 4 can reciprocate with the film dividing. The right end of the film dividing platform 4 is fixedly connected with a film receiving platform 5 through bolts. The ends of the film dividing platform 4 and the film receiving platform 5 that are close to each other do not contact and form a film dividing gap. The end of the film dividing platform 4 facing the film receiving platform 5 is arc-shaped, so that the film material can be smoothly recovered after film dividing. The front and rear inner walls of the feeding frame 2 are provided with a pressure roller 9 and a plurality of guide rollers 33 through electric shafts. The pressure roller 9 and the plurality of guide rollers 33 are respectively located on the upper and lower sides of the bearing platform 72. The pressure roller 9 is located between the pressure plate 71 and the feeding roller 31. The feeding roller 31 is wound with a film material.Figure 3 The end of the film material sequentially passes through the pressure roller 9, under the pressure plate 71, the film separation gap, and the plurality of guide rollers 33, and is connected with the take-up roller 32. During feeding, the take-up roller 32 winds, and the pay-off roller 31 unwinds, so that the film material moves along the pressure roller 9, the film separation platform 4, and the plurality of guide rollers 33. When the film material with the film sheet moves to the film separation platform 4, the film separation platform 4 moves laterally under the action of the electric sliding table, generates a lateral force on the film material, assists the film sheet to separate from the film material, and enables the film sheet to continue to move laterally to the T-shaped silica gel sheet 55, and the film material moves along the film separation gap to the take-up roller 32 and is wound.

[0033] The surface of the guide roller 33 is sleeved with a silica gel rectangular tooth, so that when the film separation platform 4 moves laterally, it can be deformed to a certain extent, so that the film material is not easily subjected to excessive stress when moving, the film material is protected from being broken due to excessive stress, and the stable feeding of the equipment is effectively ensured.

[0034] The pressure plate 71 is not in contact with the bearing platform 72, and a gap of 3-5 mm exists between the two, facilitating the film material to pass through. The pressure plate 71 is mainly used to limit the film material, so that it is not easy to bulge upward or collapse downward during movement, but can stably maintain a horizontal direction to move to the film separation platform 4.

[0035] As shown in the figure, Figure 4 c represents the electric sliding table. The film receiving platform 5 includes two Z-shaped connecting plates 51 fixedly connected to the tail of the film separation platform 4 through bolts, a film receiving plate 52 fixedly connected to the upper ends of the two Z-shaped connecting plates 51, and a plurality of T-shaped silica gel sheets 55 attached to the upper end of the film receiving plate 52. The lower end of the film receiving plate 52 is provided with a film separation detection unit, which includes a mounting strip 53 fixedly connected between the mutually close end portions of the two Z-shaped connecting plates 51, and a plurality of outer lasers 54 mounted on the lower end of the mounting strip 53. The plurality of outer lasers 54 correspond to the plurality of T-shaped silica gel sheets 55, respectively. A plurality of monitoring long holes 501 are formed in the T-shaped silica gel sheets 55 and the film receiving plate 52, and a plurality of light transmission holes corresponding to the outer lasers 54 are also formed in the mounting strip 53. After film separation, the film sheets gradually move toward the T-shaped silica gel sheets 55 under the action of the film receiving platform 5, and gradually block the monitoring long holes 501 on the T-shaped silica gel sheets 55. When the film separation is successful, the plurality of film sheets in the same column synchronously block the plurality of monitoring long holes 501, as shown in the figure. Figure 5At this time, the laser light emitted by the outer laser 54 passes through the light transmission hole and the two monitoring long holes 501 in turn and reaches the diaphragm, so that the data received by the multiple outer lasers 54 is synchronously reduced and tends to be consistent. When the diaphragm appears abnormal to cause the data of the multiple outer lasers 54 to change out of synchronization, it indicates that the film material is inclined, causing the multiple diaphragms in the same column to move inconsistently. When the data of a certain outer laser 54 is obviously greater than the data on the remaining outer lasers 54, it indicates that part of the diaphragm is not successfully separated from the film material and is collected with the film material. According to the data change of the multiple outer lasers 54, the film separation situation can be monitored in real time, so that the abnormality can be detected in time, the film material can be corrected in time, the situation that the diaphragm cannot be separated from the film material continuously occurs is effectively avoided, and the film separation precision is ensured.

[0036] The two limiting strips 401 fixedly connected to the upper end of the film separation platform 4 are symmetrical to each other, and the distance between the two limiting strips 401 is consistent with the width of the film material. The limiting strip 401 is used for limiting the film material, so that the film material is limited between the two limiting strips 401, and the possibility of film material deviation is reduced.

[0037] The monitoring long holes 501 on the multiple T-shaped silica gel pieces 55 correspond to and overlap with the multiple monitoring long holes 501 on the film receiving plate 52. The monitoring long hole 501 is a long hole with semicircles at both ends. The light transmission hole corresponds to the center of the semicircle close to the film separation platform 4, so that when the diaphragm is just separated from the film material and reaches the T-shaped silica gel piece 55, it can be monitored.

[0038] As Figures 6-7 Two monitoring grooves corresponding to the lower end of the pressing plate 71 are dug in the upper end of the bearing platform 72. The monitoring grooves are located below the pressing plate 71, and the film deviation monitoring unit is arranged in the monitoring groove. The left and right edges of the film material are flush with the edges of the two monitoring grooves close to each other. When the film material is normally not deviated during feeding, the two edges are close to the edges of the monitoring grooves and do not approach the film deviation monitoring unit, so that the film deviation monitoring unit is not triggered. When the deviation occurs, the film deviation monitoring unit on the deviated side is triggered, so that the monitoring of whether the film material is deviated can be realized.

[0039] The film deviation monitoring unit includes multiple inner lasers 11 installed at the bottom of the monitoring groove, a partition plate 10 fixedly connected to the inner wall of the monitoring groove, and multiple film sensing strips 8 fixedly connected to the lower end of the pressing plate 71. The top of the multiple film sensing strips 8 is located directly above the multiple inner lasers 11. Figure 8, the film sensing strip 8 comprises a pre-deformation strip 81, a light-blocking block 82 fixedly connected to the middle of the pre-deformation strip 81, and a counterweight block 83 fixedly connected to the lower end of the light-blocking block 82, the partition plate 10 and the counterweight block 83 are both hard transparent structures, the pre-deformation strip 81 is a flexible transparent structure, the light-blocking block 82 is a hard opaque structure, and the light-blocking block 82 is close to and lower than the edge of the detection groove, so that when the film extrudes the pre-deformation strip 81, the deformation amount at the stress position is the largest, the light-blocking block 82 close to the position can change position under the extrusion of the film material, which facilitates the dislocation with the laser beam, and the counterweight block 83 is in a vertical state, for example Figure 9 , in the figure, d represents the laser beam, at this time, the film sensing strip 8 is not in contact with the film material and is not stressed, and is in a natural vertical state, the laser emitted by the inner laser 11 coincides with the central axis of the vertical film sensing strip 8, and the light beam is blocked when reaching the light-blocking block 82, so that the data is stable, and when the film material deviates, the edge thereof gradually approaches the film sensing strip 8 on the deviation side and gradually extrudes the film sensing strip 8, due to the flexibility of the pre-deformation strip 81, the position of the light-blocking block 82 changes after being stressed, and gradually dislocates from the laser beam emitted by the inner laser 11, so that the data abnormally increases, based on which it can be judged that the film material deviates, and the more the number of inner lasers 11 whose data changes changes, the greater the deviation amplitude of the film.

[0040] In addition, when the film sensing strip 8 is in a vertical state without external force, the lower end of the film sensing strip 8 is in contact with the partition plate 10, the counterweight block 83 used as a counterweight is made of silica gel material and has a certain weight to stabilize the vertical pre-deformation strip 81, and at the same time, the density is not too large, so that the weight is not too large, and when the film material is extruded, it can be smoothly deformed and displaced.

[0041] In use, only the inner laser 11 closest to the film material is in an open state, and when the data of the inner laser 11 changes obviously, the remaining inner lasers 11 on the same side are controlled to be opened in turn, and the specific way of opening in turn is that after the data of the previous inner laser 11 changes, the next inner laser 11 is controlled to be opened, so that the inner lasers 11 do not need to be opened in advance, and the energy consumption can be reduced.

[0042] In summary, through the setting of the film offset monitoring unit, the movement of the film material can be monitored before the film material is divided, and the offset abnormality of the film material can be found before the film material is divided, so that the staff can timely correct the film material, so that the film material stably reaches the film dividing gap, and then the film is accurately divided, the film precision is effectively improved, the problem of increasing the material throwing rate caused by the film offset is reduced, the material waste is greatly reduced, and under the cooperation of the film receiving platform and the film dividing detection unit, on the one hand, the setting of the film receiving platform can provide support for the film piece after the film is divided, so that the film piece is effectively prevented from falling or failing to be smoothly separated from the film material, and on the other hand, the film output situation can be monitored, so that the film output abnormality can be found in time, and then the staff can timely make corresponding correction, so that the film output precision is further improved, and the material throwing rate is reduced.

[0043] The second embodiment is as follows:

[0044] The present embodiment is improved on the basis of the first embodiment, and the remaining parts remain the same as the first embodiment.

[0045] Figures 10-11 It is shown that the pressing roller 9 comprises a roller body 91 and a transverse sleeve roller 92 sleeved outside the roller body 91, the roller body 91 is provided with two corresponding sliding rails 901, the transverse sleeve roller 92 is fixedly connected with two sliding blocks 94 located in the two sliding rails 901, and the two ends of the sliding block 94 are provided with electric push rods 93 on the inner walls of the sliding rails 901, and the inner wall of the transverse sleeve roller 92 is attached to the outer wall of the roller body 91.

[0046] When the film offset monitoring unit detects that the movement of the film material deviates from the predetermined track, the control center can control the electric push rod 93 away from the side of the film offset monitoring unit to be shortened, and the other electric push rod 93 is synchronously elongated, so as to drive the transverse sleeve roller 92 to move in the opposite direction of the roller body 91 and the film offset direction, and then drive the film material in contact with it to move in the opposite direction of the offset direction, until the two film offset monitoring units are restored to normal and are not triggered, the movement of the transverse sleeve roller 92 along the axis of the roller body 91 is stopped, so as to achieve self-correction of the film offset, compared with the manual correction of the first embodiment, automatic correction without stopping can be realized, so that the whole feeding process is not easy to be interrupted, continuous and stable precise feeding is achieved, and the feeding efficiency is effectively ensured.

[0047] In combination with the current actual demand, the above-mentioned embodiments adopted by the present application are not limited to this, various changes made within the knowledge range of those skilled in the art without departing from the concept of the present application still fall within the protection range of the present application.
