Description

Technical Field

[0001] This application relates to the field of PC gasket production equipment technology, and in particular to a PC gasket composite material tape flipping and guiding device. Background Technology

[0002] PC gaskets have a wide range of applications, including as lens back covers for mobile phones. During the production process, PC gaskets are mounted on conveyor belts for processing and transported via conveyor belts. During the processing of PC gaskets, the conveyor belts need to be flipped.

[0003] During the material strip flipping operation, the material strip is prone to swaying and deviation, and may experience jamming, wrinkling, and deviation. The material strip flipping is not smooth, which affects the continuous production and processing of PC gaskets. Summary of the Invention

[0004] In order to improve the smoothness of the PC gasket composite strip flipping guide device during use, this application provides a PC gasket composite strip flipping guide device.

[0005] This application provides a PC gasket composite strip flipping and guiding device, which adopts the following technical solution: A PC gasket composite strip flipping and guiding device includes an infeed assembly, a guide assembly, and an outlet assembly. The guide assembly is located between the infeed assembly and the outlet assembly. The guide assembly includes a second support frame, a fixed rod is mounted on the second support frame, a material blocking assembly is mounted on the fixed rod, a support rod is mounted on the second support frame and faces the fixed rod, a movable piece is movably mounted on the support rod, and a guide block for guiding the strip is mounted on the movable piece.

[0006] By adopting the above technical solution, the feeding component conveys the material belt to the guiding component, the blocking component limits the material belt to reduce large-scale swaying of the material belt; the movable plate can be adjusted in position and angle on the support rod, driving the guide block to adapt to the material belt conveying path, the guide block guides and flips the material belt, reduces the resistance during the flipping process, improves the smoothness of the flipping, and the material belt after flipping is output by the discharge component, ensuring continuous and stable processing of PC gasket material belt.

[0007] In one specific implementation, a first connecting rod is mounted on the guide block, an upper guide plate is hinged to the first connecting rod, a first spring is connected to the upper guide plate, and the end of the first spring away from the upper guide plate is connected to the guide block. A second connecting rod is mounted on the guide block, the second connecting rod is located on the side of the upper guide plate away from the first connecting rod, a lower guide plate is hinged to the second connecting rod, a second spring is mounted on the lower guide plate, and the end of the second spring away from the lower guide plate is connected to the guide block.

[0008] By adopting the above technical solution, the material strip travels between the upper guide plate and the lower guide plate. The upper guide plate and the lower guide plate are respectively hinged and, together with the first spring and the second spring, can achieve adaptive elastic floating to adapt to the thickness fluctuation of the material strip and avoid hard squeezing and scratching the material strip. At the same time, the upper guide plate and the lower guide plate can change the deflection angle to adapt to different flipping angle requirements, and synchronously guide and constrain the upper and lower surfaces of the material strip to reduce material strip wrinkles and deviation.

[0009] In one specific implementation, a third screw is rotatably mounted on the guide block, a guide rod is mounted on the guide block, a lifting plate is threadedly connected to the third screw, the lifting plate is slidably connected to the guide rod, and a first push rod is mounted on the lifting plate, the first push rod abutting against the upper guide plate.

[0010] By adopting the above technical solution, rotating the third screw causes the lifting plate to move linearly up and down along the guide rod, which drives the first push rod to push against the upper guide plate, thus accurately adjusting the deflection angle of the upper guide plate. The guide rod limits and guides the lifting plate, preventing it from rotating synchronously with the third screw, and ensuring that the adjustment action is stable and reliable.

[0011] In one specific implementation, the end of the first push rod that abuts against the upper guide plate is spherical.

[0012] By adopting the above technical solution, the contact between the spherical end and the upper guide plate is changed from surface contact to point contact. When the upper guide plate deflects at an angle, jamming and scraping can be avoided, ensuring that the push rod can smoothly adjust the angle of the upper guide plate.

[0013] In one specific implementation, a base is mounted on the guide block, a gear is rotatably mounted on the base, a first rack is mounted on the lifting plate and meshes with the gear, a guide seat is mounted on the guide block and is located on the side of the gear away from the first rack, a second rack is slidably mounted on the guide seat and meshes with the gear, a second push rod is mounted on the second rack and abuts against the lower guide plate.

[0014] By adopting the above technical solution, the lifting plate moves the first rack synchronously when it is raised and lowered, and drives the second rack to move in the opposite direction through gear transmission, so as to realize the synchronous reverse movement of the first push rod and the second push rod. The angle adjustment of the upper guide plate and the lower guide plate can be completed simultaneously. The opening and closing tilt angle of the upper and lower guide plates can be changed synchronously with one adjustment. The adjustment efficiency is high, the angle matching degree of the upper and lower guide plates is good, and it is suitable for the channel forming of the material belt flipping.

[0015] In one specific implementation, the material blocking assembly includes a movable block slidably mounted on the fixed rod, a first screw threadedly connected to the movable block, and a second baffle mounted on the movable block.

[0016] By adopting the above technical solution, the movable block can slide along the fixed rod to adjust the lateral position of the second baffle, adapting to material strips of different widths. Tightening the first screw can lock the movable block in place. The second baffle prevents the material strip from shifting laterally, limiting the swing amplitude of the material strip and further ensuring the smoothness of the material strip flipping process.

[0017] In one specific implementation, a second screw is threaded onto the support rod, and the movable piece is slidably mounted on the second screw. The movable piece is locked onto the support rod by the second screw.

[0018] By adopting the above technical solution, the second screw is loosened, and the movable piece can rotate on the support rod to adjust the installation position and tilt angle of the guide block. After the rough adjustment is completed, the second screw is tightened to lock and fix it, which can be adapted to the material conveyor angle under different working conditions.

[0019] In one specific implementation, the feeding assembly includes a first support frame, a rotating rod rotatably mounted on the first support frame, a motor for controlling the rotation of the rotating rod mounted on the first support frame, and a first baffle mounted on the rotating rod.

[0020] By adopting the above technical solution, the motor drives the rotating rod to rotate to realize the active feeding of the material belt. The first baffle limits the material belt on both sides to prevent the material belt from running off-track. The feeding component continuously guides the feeding, so that the material belt forms a buffer section between the feeding component and the guiding component, which is adapted to the intermittent feeding mode of the discharging component and avoids the material belt being pulled hard.

[0021] In one specific implementation, the discharge assembly includes a third support frame on which a first rolling rod and a second rolling rod are rotatably mounted, and on the second rolling rod are a pressing roller for pressing the material belt.

[0022] By adopting the above technical solution, the rolling roller and the first rolling rod cooperate to clamp the material belt, and the material belt is intermittently conveyed by the roller friction. The material belt is rolled and flattened after being flipped to ensure that the output material belt is flat and facilitates subsequent processing.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. This application is equipped with an adjustable guide block, which works with the upper guide plate and the lower guide plate to flip and guide the material strip. At the same time, the material blocking component restricts the lateral swing of the material strip, effectively improving the problems of jamming and wrinkling when the material strip flips, and improving the smoothness of the material strip flipping.

[0024] 2. Through the third screw, lifting plate, and gear rack mechanism, the upper and lower guide plates can be adjusted synchronously. The tilt angle of the upper and lower guide plates can be adjusted simultaneously in one operation, which is suitable for various specifications of material strips and is easy to adjust.

[0025] 3. The feeding component continuously feeds material, while the discharging component discharges material intermittently, forming a buffer belt in between to prevent the belt from being stretched and deformed. Each component can be adjusted in position and angle to adapt to different production conditions. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0037] This application discloses a PC gasket composite strip flipping and guiding device, referring to... Figure 1 and Figure 2 It includes a feeding component 1, a guiding component 2 and a discharging component 3. The guiding component 2 is located between the feeding component 1 and the discharging component 3. The feeding component 1 conveys the material belt toward the guiding component 2.

[0039] After the gasket is processed on the material strip, it will be conveyed to the rotating rod 12. The motor 13 will control the rotating rod 12 to rotate to assist in the feeding of the material strip. During the feeding process, the material strip will naturally hang down between the material guide assembly 2 and the rotating rod 12 after being fed by the rotating rod 12.

[0041] A support rod 241 is fixedly installed on the second support frame 21, facing the fixed rod 22. A second screw 242 is threadedly connected to the support rod 241, and a movable piece 243 is slidably installed on the second screw 242. The movable piece 243 is locked to the support rod 241 by the second screw 242. (Refer to...) Figure 5 and Figure 6 A guide block 25 is fixedly installed on the movable piece 243. A first connecting rod 251 is fixedly installed on the guide block 25. An upper guide plate 252 is hinged to the first connecting rod 251. A first spring 253 is fixedly connected to the upper guide plate 252. The end of the first spring 253 away from the upper guide plate 252 is fixedly connected to the guide block 25. The first connecting rod 251 and the first spring 253 are respectively located near the two sides of the upper guide plate 252. A second connecting rod 254 is fixedly installed on the guide block 25. The second connecting rod 254 is located on the side of the upper guide plate 252 away from the first connecting rod 251. A lower guide plate 255 is hinged to the second connecting rod 254. A second spring 256 is fixedly installed on the lower guide plate 255. The end of the second spring 256 away from the lower guide plate 255 is fixedly connected to the guide block 25.

[0042] A third screw 261 is rotatably mounted on the guide block 25, and a guide rod 262 is fixedly mounted on the guide block 25. A lifting plate 263 is threadedly connected to the third screw 261. The lifting plate 263 is slidably connected to the guide rod 262. A first push rod 264 is fixedly mounted on the lifting plate 263. The first push rod 264 abuts against the upper guide plate 252. The end of the first push rod 264 that abuts against the upper guide plate 252 is spherical.

[0043] Reference Figure 6 , Figure 7 and Figure 8A base 271 is fixedly mounted on the guide block 25, and a gear 272 is rotatably mounted on the base 271. A first rack 273 is fixedly mounted on the lifting plate 263, and the first rack 273 is positioned on the side of the gear 272 close to the first push rod 264, meshing with the gear 272. A guide seat 274 is fixedly mounted on the guide block 25, positioned on the side of the gear 272 away from the first rack 273. A guide groove 2741 is provided on the guide seat 274, and a second rack 275 is slidably mounted on the guide seat 274 through the guide groove 2741, meshing with the gear 272. A second push rod 276 is fixedly mounted on the second rack 275, and the second push rod 276 abuts against the lower guide plate 255.

[0044] The material strip is passed between the upper guide plate 252 and the lower guide plate 255. The second screw 242 is loosened, and the guide block 25 is rotated to adjust its tilt angle for initial adjustment. After adjustment, the second screw 242 is rotated to lock the movable piece 243. Then, the third screw 261 is rotated, which controls the lifting plate 263 to descend. The lifting plate 263 drives the first push rod 264 to move downward, and the first push rod 264 presses against the upper guide plate 252 to adjust its tilt angle. Simultaneously, the lifting plate 263 will also drive the first rack 273 to move downward, the first rack 273 will drive the gear 272 to rotate, the gear 272 will drive the second rack 275 to move upward, the second rack 275 will drive the second push rod 276 to move upward, and the second push rod 276 will push the lower guide plate 255 to move and adjust the angle of the lower guide plate 255 in a synchronous manner. This allows the upper guide plate 252 and the lower guide plate 255 to adjust their tilt angles according to the movement path of the material belt. The material belt passes through the upper guide plate 252 on one side and rests on the second baffle 233 on the other side, preventing the material belt from swinging too much during the transportation and pulling process. This makes the material belt more smooth and the flipping process more natural.

[0045] Reference Figure 1 and Figure 9 The discharge assembly 3 includes a third support frame 31, on which a first rolling rod 32 and a second rolling rod 33 are rotatably mounted, and a pressing roller 34 for pressing the material belt is fixedly mounted on the second rolling rod 33.

[0046] The material strip is flipped over and passed between the rolling roller 34 and the first rolling rod 32, and is rolled and conveyed by the rolling roller 34 and the first rolling rod 32. In this embodiment, the material strip is automatically conveyed upstream toward the rotating rod 12, and the material strip is conveyed and pulled downstream by a power source. The conveying method is that the rotating rod 12 continuously releases material to the material feeding assembly 2, and the material discharging assembly 3 intermittently conveys the material strip downstream. For example, after the material strip released by the rotating rod 12 is three centimeters long, the material discharging assembly 3 conveys three centimeters of material strip downstream, and then the material discharging assembly 3 waits for the rotating rod 12 to release another three centimeters of material strip before conveying it downstream again.

[0047] The implementation principle of this application embodiment is as follows: PC gasket composite material strip is continuously released through the rotating rod 12 of the feeding assembly 1, and the material strip is conveyed downward to the guiding assembly 2; firstly, the second screw 242 is loosened, and the overall tilt angle of the movable piece 243 and the guide block 25 is adjusted to complete the coarse positioning, and then the second screw 242 is locked; the material strip passes between the upper guide plate 252 and the lower guide plate 255, and the third screw 261 is rotated to drive the lifting plate 263 to rise and fall, the first push rod 264 pushes the upper guide plate 252 to change the tilt angle, and at the same time, the first rack 273, the gear 272, and the second rack 275 are driven, and the second push rod 276 synchronously adjusts the tilt angle of the lower guide plate 255 in the opposite direction to match the material strip flipping path; the second baffle 233 of the baffle assembly 23 restricts the lateral swing of the material strip, and the material strip completes the flipping under the guidance of the upper and lower guide plates; the flipped material strip is sent into the discharge assembly 3, and the rolling roller 34 cooperates with the first rolling rod 32 to intermittently pull and output the material strip. The feeding component 1 continuously feeds material, while the discharging component 3 discharges material intermittently, with a buffer section reserved in between to prevent the material belt from being pulled hard, thus achieving smooth and stable rotation of the material belt.

[0048] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
