Description

Technical Field

[0001] This utility model relates to the field of protective film processing technology, specifically a feeding device for protective film processing. Background Technology

[0002] In the field of protective film processing, the efficiency and accuracy of the feeding process have a crucial impact on the overall production process and product quality. Traditional protective film feeding devices mostly have a fixed limiting structure, with the limiting rod directly fixed to the base by screws. Therefore, the limiting size is not adjustable or has a very limited adjustment range. This means that the same feeding device can only be used for protective films of a specific size. When faced with processing tasks for protective films of different specifications and sizes, companies have to frequently change feeding devices or customize special limiting components. This not only increases equipment procurement costs and production preparation time, but also reduces the flexibility and versatility of the production line, making it impossible to quickly respond to changes in market demand for protective film products of different sizes.

[0003] Therefore, we have designed a feeding device for protective film processing to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a feeding device for protective film processing, thereby solving the problems mentioned in the background art.

[0019] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1: Please refer to Figures 1-3 This protective film processing feeding device mainly consists of a limiting structure, a feeding structure, and a conveying structure. The limiting structure is set on a base 8, which is fixed with two sets of transverse slide rails 1 and two sets of longitudinal slide rails 4. These four sets of slide rails are arranged in a cross shape. A transverse slider 2 is slidably installed on each set of transverse slide rails 1, and a longitudinal slider 5 is slidably installed on each set of longitudinal slide rails 4. Each slider is fixed with a pair of vertically set limiting rods 7. A transverse lead screw 3 and a longitudinal lead screw 6 are rotatably installed on the base 8 through bearing seats. Two nuts on the transverse lead screw 3 are fixed to two transverse sliders 2 respectively, and two nuts on the longitudinal lead screw 6 are fixed to two longitudinal sliders 5 respectively. When the limiting structure needs to limit the protective film of different sizes, the operator can rotate the knob at the end of the transverse lead screw 3 or the longitudinal lead screw 6. Since the left and right half of the lead screw has opposite screw directions, when the lead screw is rotated, the two nuts on the lead screw will drive the two sliders to move relative to or away from each other along the slide rail, thereby adjusting the distance between the limiting rods 7.

[0021] The feeding structure includes a bracket 9 fixed on a base 8. A hydraulic cylinder 10 with its output rod pointing vertically downwards is mounted on the bracket 9. A servo motor 11 with its output shaft pointing vertically downwards is mounted on the output rod of the hydraulic cylinder 10. Two horizontally arranged and symmetrical rotating arms 12 are mounted on the output shaft of the servo motor 11. Two fixing parts 13 are mounted on each rotating arm 12. A vacuum suction cup 14 is mounted at the bottom of each fixing part 13. The air holes of each vacuum suction cup 14 are connected to an external vacuum suction cup control system through a hose. When feeding, the hydraulic cylinder 10 drives the servo motor 11 to move downwards, so that the vacuum suction cup 14 on one of the rotating arms approaches the protective film. After the vacuum suction cup 14 adsorbs the protective film, the hydraulic cylinder 10 retracts, lifting the protective film. The servo motor 11 can drive the rotating arm 12 to rotate, thereby transferring the adsorbed protective film to the conveyor. When the hydraulic cylinder 10 drives the servo motor 11 to move downwards again, the vacuum suction cup 14 releases the protective film transferred to the top of the conveyor, thereby placing the protective film on the conveyor belt of the conveyor, realizing the feeding operation of the protective film.

[0022] The feeding structure includes an electric cylinder 15 and a support plate 16. The support plate 16 is horizontally positioned and located in the middle of the four pairs of limiting rods 7 of the limiting structure. The electric cylinder 15 is installed at the bottom of the base 8, with its output rod pointing vertically upward. Its top end passes through the through hole on the base 8 and is fixed to the bottom of the support plate 16. When using the device, the protective film can be stacked on the support plate 16. The limiting rods 7 around the perimeter can limit the stacked protective film to prevent it from tilting or collapsing. When the top protective film is removed, the overall height of the stacked protective film will decrease. At this time, the electric cylinder 15 drives the support plate 16 to move upward, which can raise the overall height of the stacked protective film so that the vacuum suction cup 14 of the feeding structure can grab the top protective film. A photoelectric sensor and a controller can be installed on the base 8. The photoelectric sensor is used to monitor the height of the stacked protective film in real time. When the photoelectric sensor detects that the height of the stacked protective film is lower than the preset height, the controller starts the electric cylinder 15 to drive the support plate 16 to move upward until the height of the stacked protective film reaches the preset height. The entire device is connected to the controller, which controls its automatic feeding.

[0023] Example 2: In actual production, in order to more accurately adjust the spacing of the limit rods 7, two first scales 17 are fixed on the base 8. One is set horizontally next to one of the horizontal sliders 2 of the limit structure, and the other is set vertically next to one of the vertical sliders 5 of the limit structure. When adjusting the spacing of the limit rods 7, the operator can observe the position of the slider on the scale, thereby accurately controlling the spacing of the limit rods 7. At the same time, both the horizontal lead screw 3 and the vertical lead screw 6 are trapezoidal lead screws. These lead screws have a self-locking function, which can ensure that after the spacing of the limit rods 7 is adjusted, the slider will not move arbitrarily due to external force, thereby ensuring the stability of the limit.

[0024] Example 3: The fixing component 13 includes a lower clamping plate 1301, a threaded post 1302, an upper clamping plate 1303, and a nut 1304. A vacuum suction cup 14 is fixed to the bottom of the lower clamping plate 1301, and the threaded post 1302 is fixed to the top of the lower clamping plate 1301. The upper clamping plate 1303 has a through hole through which only the threaded post 1302 can pass. The rotating arm 12 has a strip-shaped through hole. The threaded post 1302 passes through the strip-shaped through hole on the rotating arm 12 and the through hole on the upper clamping plate 1303 sequentially from bottom to top. Finally, it is connected to the nut 1304 by a thread and tightened. When adjustment is required... When positioning the vacuum suction cup 14 on the rotating arm 12, the operator can first loosen the nut 1304, then move the lower clamping plate 1301 and the vacuum suction cup 14, so that the threaded post 1302 moves within the strip-shaped through hole of the rotating arm 12. After adjusting to the appropriate position, tighten the nut 1304. In addition, a second scale 18 parallel to its strip-shaped through hole is fixed on the rotating arm 12. When adjusting the position of the vacuum suction cup 14, the operator can refer to the reading of the second scale 18 to achieve more precise position adjustment to meet the adsorption requirements of protective films of different sizes.

[0025] Example 4: The support plate 16 is a cross-shaped plate with multiple horizontal and vertical elongated notches around its perimeter. The limiting rod 7 can move horizontally within the elongated notches of the support plate 16. During the adjustment of the spacing of the limiting rod 7, when the support plate 16 moves up and down or the limiting rod 7 moves horizontally, the limiting rod 7 and the support plate 16 do not obstruct each other. At the same time, since the support plate 16 is cross-shaped, its structure is stable and can evenly support the protective film, ensuring that the protective film remains stable during the feeding process.

[0026] Usage Procedure: Before use, adjust the spacing of the limiting rods 7 according to the size of the protective film. Rotate the horizontal lead screw 3 and the vertical lead screw 6 by turning the knob, so that the lead screw nut drives the limiting rods 7 to move relative to or away from each other through the slider, until the front-to-back spacing and left-to-right spacing of the limiting rods 7 are adjusted to be slightly larger than the length and width of the protective film. Then, place the stacked protective film on the support plate 16. Preset the height of the stacked protective film on the controller. After the preparation is completed, start the device. The electric cylinder 15 starts and lifts the stacked protective film on the placement plate 16 to the preset height. Then, the hydraulic cylinder 10 drives the servo motor 11 to move downward, so that the vacuum suction cup 14 on one of the rotating arms 12 approaches the stacked protective film. After the suction cup 14 adsorbs the first protective film, the hydraulic cylinder 10 retracts, lifting the protective film. Then, the servo motor 11 drives the rotating arm 12 to rotate 180° clockwise, transferring the adsorbed first protective film onto the conveyor. Next, the hydraulic cylinder 10 drives the servo motor 11 to move downwards, and another rotating arm 12 approaches and adsorbs the second protective film. At the same time, the vacuum suction cup 14 releases the first protective film, thus placing the first protective film onto the conveyor belt of the conveyor to be conveyed to the next process. Then, the hydraulic cylinder 10 retracts, and the servo motor 11 drives the rotating arm 12 to rotate 180° counterclockwise again, placing the second protective film onto the conveyor belt of the conveyor. This process is repeated to achieve continuous feeding of protective films.
