Description

Technical Field

[0001] The invention relates to the technical field of feeding mechanisms, and in particular to a film feeding mechanism. Background Art

[0002] The material feeding method for shock-absorbing bladder molding is: manually place the rolled material, with the rubber sheet inside and the base cloth outside, on a V-shaped roller, then manually tear off the base cloth and the film, and pull the film to the top of the roller, passing through 3 rollers in total until the front roller, and then vertically downward, one of the rollers is driven by a motor to rotate, driving the film to be transmitted downward to the sensor position, the servo motor starts to rotate and calculate, the roller drives the film forward to the preset length and stops, the cutter cuts horizontally, and the cut film material adheres to the bottom plate to be picked up manually, thus completing the entire film material feeding.

[0003] This type of roller feeding rack has a large vertical drop. It is necessary for workers to stand on the feeding rack every time to pull the film, which takes a long time to load and change the material. The film often sticks to the roller and is stretched, which will also cause the cut end of the film to tilt. The film often deviates left and right during the pulling process, which not only exceeds the cutting stroke and cannot be cut, but also once the film is deformed, the cut film will be cut by mistake, resulting in a larger feeding tolerance. If it is too short or too long, it will cause material waste. At the same time, this feeding method cannot be used for automated production. Summary of the invention

[0028] See also Figures 1 to 3The present embodiment discloses a film feeding mechanism, comprising a first bracket 1, a release mechanism 2, a winding mechanism 3, a roller mechanism 4, a tensioning mechanism 5, a second bracket 6, a conveying mechanism 7, a visual inspection mechanism 8, a feeding and laminating mechanism 9, a transition plate 10, and a cutting mechanism 11. The release mechanism 2, the winding mechanism 3, and the roller mechanism 4 are all arranged on the first bracket 1, the conveying mechanism 7, the visual inspection mechanism 8, the feeding and laminating mechanism 9, the transition plate 10, and the cutting mechanism 11 are all arranged on the second bracket 6, the tensioning mechanism 5 is arranged between the first bracket 1 and the second bracket 6, the transition plate 10 is arranged between the conveying mechanism 7 and the feeding and laminating mechanism 9, the visual inspection mechanism 8 is arranged above the feeding and laminating mechanism 9, and the visual inspection mechanism 8 is used to detect the film position and the conveying length.

[0029] Specifically, the coil is installed on the release mechanism 2 and separated at the roller mechanism 4. The separated base fabric 12 is wound on the winding mechanism 3. The separated film 13 bypasses the tensioning mechanism 5, the conveying mechanism 7, the transition plate 8, and the feeding and bonding mechanism 9 in turn, wherein the film 13 is tensioned and released by the tensioning mechanism 5. Before cutting, the conveying length of the film 13 and the position on the feeding and bonding mechanism 9 are detected by the visual inspection mechanism 8. When the conveying length of the film 13 meets the requirements, the cutting mechanism 11 cuts the film 13. The cut film 13 is transported by the feeding and bonding mechanism 9, and then the position feedback of the film 13 on the feeding and bonding mechanism 9 is detected by the visual inspection mechanism 8. The head core rod is controlled to accurately stay and bond with the film 13, and the film and the head core rod are bonded and rotated, thereby completing the automatic feeding of the entire film.

[0030] It should be noted that the release mechanism 2, the winding mechanism 3, and the roller mechanism 4 are all available in the market.

[0031] The feeding mechanism is used for feeding, and no manual labor is required. It is suitable for automated production, and can provide real-time feedback on film position and real-time automatic film cutting. The film is cut to precise size, and the dimensional tolerance of cutting and deformation waste of materials are reduced. Compared with the original manual labor of constantly moving around to pick up materials, the labor load is reduced, and the feeding efficiency is improved.

[0032] Furthermore, a film roller 101 is fixed on the first bracket 1 near the tensioning mechanism 5 to support the film 13 .

[0033] In the reference Figure 3The tensioning mechanism 5 includes a third bracket 51, a counterweight rod 52 and a sensor 53. The third bracket 51 is provided with a counterweight rod 52 that can move vertically. The separated film 13 is conveyed to the conveying mechanism 7 after passing through the counterweight rod 52. The sensors 53 are respectively arranged at different heights for detecting the height of the film 13. In this embodiment, the sensors are arranged in three groups from high to low. Specifically, the counterweight rod 52 is driven to move vertically. When the highest sensor 53 detects the film 13, the release mechanism 2 starts to release the coil. When the middle sensor 53 detects the film 13, the release mechanism 2 can continue to release the coil and issue an early warning, indicating that the length of the film 13 reaches the early warning value. When the lowest sensor 53 detects the film 13, the release mechanism 2 stops releasing the coil to prevent excessive release of the coil.

[0034] In this embodiment, the conveying mechanism 7 is an anti-sticking belt conveying mechanism to prevent the film 13 from being adhered and affecting the conveyance of the film 2 .

[0035] The visual inspection mechanism 8 includes a fourth bracket 81 , a light source 82 and a camera 83 . The fourth bracket 81 is fixed on the second bracket 6 . The light source 82 and the camera 83 are both fixed on the fourth bracket 81 and are located above the feeding and laminating mechanism 9 .

[0036] See also Figure 4 The feeding and laminating mechanism 9 includes a base 91, a sliding component 92, a driving motor 93, a sponge belt transmission mechanism 94, a rotating component 95, a connecting rod, and a driving cylinder 96. The base 91 is movably arranged on the second bracket 6 through the sliding component 92. The driving motor 93 and the sponge belt transmission mechanism 94 are both arranged on the base 91. The output end of the driving motor 93 is connected to the sponge belt transmission mechanism 94 to provide power for the sponge belt transmission mechanism 94. One end of the sponge belt transmission mechanism 94 close to the transition plate 10 is arranged on the base 91 through the rotating component 95, and the other end is arranged on the base 91 through a connecting rod (not shown in the figure) arranged at the bottom. A driving cylinder 96 is also fixed on the base 91, and the output end of the driving cylinder 96 is vertically arranged and connected to the connecting rod.

[0037] Specifically, the base 91 is moved by the sliding assembly 92, so that the feeding and bonding mechanism 9 moves forward as a whole, away from the transition plate 10, waiting for the arrival of the head mandrel, and the stop position of the head mandrel is detected by the visual detection mechanism 8. The feedback of the size of the film 13 from the edge of the sponge belt conveyor mechanism 94 is used to control the head mandrel to accurately stay and fit the film 13, and then drive the driving cylinder 96 to make the end of the sponge belt conveyor mechanism 94 away from the rotating assembly 95 rotate upward with the rotating assembly 95 as the center, and the film 13 is rotated to fit the head mandrel, thereby completing the automatic feeding of the entire film.

[0038] The transition plate 10 is provided with blowing holes and cutting seams. Through the setting of the blowing holes, gas is blown through the film 13 on the transition plate 10, which can not only prevent the film 13 from wrinkling when passing through the transition plate 10, but also prevent the cut film 13 from adhering to the transition plate 10.

[0039] The cutting mechanism 11 includes a cutting bracket 111, a cutting drive assembly 112, a cutting cylinder, and a cutting knife. The cutting bracket 111 is fixed on the second bracket 6 on both sides of the transition plate 10. The cutting drive assembly 112 is arranged on the cutting bracket 111. The cutting cylinder is fixed on the output end of the cutting drive assembly 12, so that the cutting cylinder can move along the length direction of the transition plate 10. The output end of the cutting cylinder is connected to the cutting knife, and the cutting knife is located directly above the cutting seam.

[0040] Specifically, the cutting knife is driven downward by the cutting cylinder, and then the cutting cylinder is driven to move along the length direction of the transition plate 10 by the cutting drive assembly 102 to cut the film 13 .

[0041] The second bracket 6 is also provided with a brush roller 14, which is rotatably arranged on the top of the sponge belt conveyor mechanism 94. When the cut film passes through the brush roller 14, the brush roller 14 rotates to smooth the film 13 to prevent the film 13 from wrinkling.

[0042] The working principle of this embodiment is as follows: by driving the release mechanism 2, the coil is released and separated at the roller mechanism 4, the separated base fabric 12 is rolled up on the winding mechanism 3, and the separated film 13 bypasses the tensioning mechanism 5, the conveying mechanism 7, the transition plate 8, and the feeding and laminating mechanism 9 in turn, wherein the film 13 is tensioned and released by the tensioning mechanism 5, and the counterweight rod 52 is driven to move vertically. When the highest sensor 53 detects the film 13, the release mechanism 2 starts to release the coil. When the middle sensor 53 detects the film 13, the release mechanism 2 can continue to release the coil and issue an early warning, indicating that the length of the film 13 has reached the early warning value. When the lowest sensor 53 detects the film 13, the release mechanism 2 stops releasing the coil to prevent excessive release of the coil.

[0043] Before cutting, the conveying length of the film 13 and its position on the feeding and laminating mechanism 9 are detected by the visual detection mechanism 8. When the conveying length of the film 13 meets the requirements, the cutting mechanism 11 cuts the film 13. The cut film 13 is conveyed by the feeding and laminating mechanism 9, and the base 91 is driven to move by the sliding component 92, so that the feeding and laminating mechanism 9 moves forward as a whole, away from the transition plate 10, waiting for the arrival of the head mandrel. The stop position of the head mandrel is the size feedback of the film 13 from the edge of the sponge belt conveyor mechanism 94 detected by the visual detection mechanism 8, so as to control the head mandrel to stay accurately and fit with the film 13, and then drive the driving cylinder 96, so that the end of the sponge belt conveyor mechanism 94 away from the rotating component 95 rotates upward with the rotating component 95 as the center, and the film 13 is rotated in fit with the head mandrel, thereby completing the automatic feeding of the entire film.
