Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber granule technology, specifically to a raw material conveying device for the production of automotive seals. Background Technology
[0002] The main raw materials used in the production of automotive seals are rubber, plastics, and metal skeletons, with rubber being the most critical material. Depending on the application environment of the seals, materials such as EPDM, NBR, FKM, and silicone rubber are selected. These materials have the characteristics of high and low temperature resistance, oil resistance, aging resistance, and ozone resistance. At the same time, steel wire or metal skeletons are used to enhance the strength and stability of the seals. The reasonable combination of different raw materials can ensure that automotive seals have good air tightness, water tightness, durability, and safety.
[0003] An existing rubber granule quantitative conveying device includes a storage tank, a feeding and metering mechanism, and a screw feeding mechanism. The feeding and metering mechanism includes an impeller housing, a drive shaft, and impeller plates. The impeller housing is fixedly installed at the bottom of the storage tank and communicates with its discharge port. The discharge port of the impeller housing is connected to the screw feeding mechanism. The drive shaft is located at the center of the impeller housing, and impeller plates are installed at equal intervals on the drive shaft.
[0004] However, although the above-mentioned conveying device can achieve quantitative conveying of materials through the feeding chamber, the volume of the feeding chamber is fixed and cannot be adjusted. Therefore, it can only convey a specific amount of material quantitatively and cannot adjust the amount of material conveyed according to actual needs, which limits the use of the entire conveying device. In view of this, we propose a raw material conveying device for automotive sealing parts production. Summary of the Invention
[0005] The purpose of this invention is to provide a raw material conveying device for the production of automotive sealing components, so as to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material conveying device for automotive sealing component production, comprising a frame, a driving device fixedly connected to the side wall of the frame, a transmission roller fixedly connected to the output end of the driving device, a conveyor belt drivingly connected to the side wall of the transmission roller, a fixing frame fixedly connected to the side wall of the frame, and an adjustment component disposed inside the fixing frame, the adjustment component comprising: The motor has a rotating frame fixedly connected to its output end, a feeding cylinder fixedly connected to the inner wall of the rotating frame, and a baffle slidably connected to the side wall of the rotating frame. An adjusting shaft, wherein a hinge rod one is hinged to the side wall of the adjusting shaft, and a hinge rod two is hinged to the end face of the hinge rod one; A feeding hopper, wherein a guide plate is fixedly connected to the side wall of the feeding hopper, a connecting rod is fixedly connected to the side wall of the feeding hopper, and a guide plate is fixedly connected to the end face of the connecting rod; The feeding pipe has a guide plate fixedly connected to its side wall.
[0007] Preferably, the motor is fixedly connected to the side wall of the fixed frame, and the baffle is located on the side of the feed cylinder near the outer wall of the rotating frame.
[0008] Preferably, the rotating frame includes two coaxial rings, and the feeding cylinder is located on the inner wall of the outer ring, enabling quantitative and timed feeding.
[0009] Preferably, the adjusting shaft is rotatably connected to the rotating frame, the second hinge rod is inserted into the inner ring, and a disc is fixedly connected to the end face of the second hinge rod, the disc being inserted into the feeding cylinder.
[0010] Preferably, the feeding hopper is fixedly connected to the inner wall of the fixed frame, the bottom of the feeding hopper is movably connected to the outer wall of the rotating frame, the first guide plate is movably connected to the baffle, and the second guide plate is movably connected to the baffle.
[0011] Preferably, the feeding pipe is fixedly connected to the inner wall of the fixed frame, and the guide plate three is movably connected to the baffle, the guide plate three pushing the baffle away from below the feeding cylinder.
[0012] Preferably, the side wall of the rotating frame is fixedly connected to an installation strip, the side wall of the installation strip is threadedly connected to an adjusting bolt, the end face of the adjusting bolt is fixedly connected to an insert rod, and the insert rod is inserted into the adjusting shaft.
[0013] Compared with the prior art, this utility model provides a raw material conveying device for the production of automotive seals, which has the following advantages: 1. This raw material conveying device for automotive sealing parts production, through its adjustable components, changes the position of the disc within the feeding cylinder to regulate the feeding amount, making the material discharge more precise. Adjustment allows for rapid switching of production line requirements, adapting to different formulas and processes, improving production flexibility, and reducing downtime caused by equipment or mold changes. Only when the cylinder opening is below the hopper or above the discharge pipe is the baffle pushed open by guide plate one and guide plate three, allowing particles to freely enter and exit. This ensures the opening is only at a designated location, guaranteeing feeding accuracy and improving feeding uniformity and stability. The follow-up baffle only moves momentarily during opening and closing, resulting in concentrated and controllable friction, reducing material accumulation, lowering maintenance costs, and minimizing material buildup and wear.
[0014] 2. The raw material conveying device for automotive sealing parts production uses adjustable bolts to precisely control the position of the insertion rod, thereby controlling the insertion depth or angle of the adjusting shaft. The threaded drive has self-locking properties, preventing the insertion rod from loosening due to vibration or rotation, thus ensuring stability and safety during the adjustment process.

[0017] like Figures 1-6 As shown, this utility model provides a technical solution: a raw material conveying device for automotive sealing parts production, including a frame 1, a drive device 2 fixedly connected to the side wall of the frame 1, a transmission roller fixedly connected to the output end of the drive device 2, a conveyor belt 3 drivingly connected to the side wall of the transmission roller, a fixed frame 4 fixedly connected to the side wall of the frame 1, and an adjustment component 5 provided inside the fixed frame 4. The adjustment component 5 includes a motor 501, a rotating frame 502, an adjustment shaft 503, a first hinge rod 504, a second hinge rod 505, a feeding cylinder 506, a baffle 507, a feeding hopper 508, a first guide plate 509, a connecting rod 510, a second guide plate 511, a discharge pipe 512, and a third guide plate 513.
[0018] In one embodiment of this utility model, a motor 501 is fixedly connected to the side wall of a fixed frame 4, and a rotating frame 502 is fixedly connected to the output end of the motor 501. A feeding cylinder 506 is fixedly connected to the inner wall of the rotating frame 502, and a baffle 507 is slidably connected to the side wall of the rotating frame 502. The baffle 507 is located on the side of the feeding cylinder 506 near the outer wall of the rotating frame 502. The rotating frame 502 includes two coaxial rings, and the feeding cylinder 506 is located on the inner wall of the outer ring. The feeding cylinder 506 realizes quantitative and timed feeding.
[0019] The adjusting shaft 503 is rotatably connected to the rotating frame 502. The side wall of the adjusting shaft 503 is hinged with a first hinge rod 504. The end face of the first hinge rod 504 is hinged with a second hinge rod 505. The second hinge rod 505 is inserted into the inner ring. The end face of the second hinge rod 505 is fixedly connected to a disc. The disc is inserted into the feeding cylinder 506.
[0020] The feeding hopper 508 is fixedly connected to the inner wall of the fixed frame 4. A guide plate 509 is fixedly connected to the side wall of the feeding hopper 508. A connecting rod 510 is fixedly connected to the side wall of the feeding hopper 508. A guide plate 511 is fixedly connected to the end face of the connecting rod 510. The bottom of the feeding hopper 508 is movably connected to the outer wall of the rotating frame 502. The guide plate 509 is movably connected to the baffle 507. The guide plate 511 is movably connected to the baffle 507.
[0021] The feeding pipe 512 is fixedly connected to the inner wall of the fixed frame 4. The side wall of the feeding pipe 512 is fixedly connected to the guide plate 3 513. The guide plate 3 513 is movably connected to the baffle 507. The guide plate 3 513 pushes the baffle 507 away from the bottom of the feeding cylinder 506.
[0022] Motor 501 drives rotating frame 502 to rotate, so that rotating frame 502 and feeding cylinder 506 pass under feeding hopper 508. Rubber particles inside feeding hopper 508 fall into feeding cylinder 506. Then, as rotating frame 502 rotates, rubber particles fall into discharge pipe 512 and then onto conveyor belt 3, realizing quantitative feeding. This helps to stabilize subsequent mixing, calendering or extrusion processes, ensuring more accurate raw material ratios and reducing fluctuations during the production of sealing parts.
[0023] Rotating the adjusting shaft 503 causes the hinge rod 1 504 and hinge rod 2 505 to move. The hinge rod 2 505 pushes the disc, changing the position of the disc in the feeding cylinder 506, thereby adjusting the feeding amount and making the feeding amount more precise. Through adjustment, production line requirements can be quickly switched to adapt to different formulas and processes, improving production flexibility and reducing downtime caused by changing equipment or molds.
[0024] During the rotation of the rotating frame 502, the second guide plate 511 pushes the baffle 507 to block the outlet of the feed cylinder 506 containing rubber granules. The first guide plate 509 and the third guide plate 513 push the baffle 507 to open the opening of the feed cylinder 506. When the feed cylinder 506 is at the bottom of the upper hopper 508 or the top of the lower pipe 512, the rubber granules can freely enter and exit the feed cylinder 506. When the feed cylinder 506 is in a non-discharge position during rotation, the outlet is blocked by the baffle 507, and the rubber granules will not fall off prematurely, avoiding contamination of the equipment or waste of raw materials. Only when the cylinder opening is below the upper hopper 508 or above the lower pipe 512 is the baffle 507 pushed open by the first guide plate 509 and the third guide plate 513, and the granules can freely enter and exit. This achieves opening only at designated positions, ensuring the accuracy of feeding and improving the uniformity and stability of feeding.
[0025] Compared to a fixed baffle ring, which rubs against particles for a long time, the fixed ring is prone to wear and jamming. The baffle 507, which rotates with the feed cylinder 506, only moves at the moment of opening and closing, so the friction is concentrated and controllable, making it less likely to accumulate material, reducing maintenance costs, and reducing material accumulation and wear.
[0026] In addition, a mounting strip 8 is fixedly connected to the side wall of the rotating frame 502, and an adjusting bolt 6 is threadedly connected to the side wall of the mounting strip 8. A plug rod 7 is fixedly connected to the end face of the adjusting bolt 6. The plug rod 7 is inserted into the adjusting shaft 503. The adjusting bolt 6 is threadedly connected to the mounting strip 8, which allows for precise control of the position of the plug rod 7, thereby controlling the insertion depth or angle of the adjusting shaft 503. The threaded drive has self-locking properties, preventing the plug rod 7 from loosening from the adjusting shaft 503 due to vibration or rotation, thus ensuring stability and safety during the adjustment process.
[0027] In this invention, during use, motor 501 drives rotating frame 502 to rotate, causing rotating frame 502 and feeding cylinder 506 to pass below feeding hopper 508. Rubber granules inside feeding hopper 508 fall into feeding cylinder 506. Then, as rotating frame 502 rotates, the rubber granules fall into discharge pipe 512 and onto conveyor belt 3. Rotating adjusting shaft 503 causes hinge rod one 504 and hinge rod two 505 to move. Hinge rod two 505 pushes the disc, changing the disc's position in the feeding... The position of the feed cylinder 506 allows for adjustment of the feeding amount, making the discharge more precise. When the feed cylinder 506 is in a non-discharge position during rotation, the outlet is blocked by the baffle 507, preventing the rubber granules from falling prematurely and avoiding contamination of the equipment or waste of raw materials. Only when the cylinder opening is below the feed hopper 508 or above the discharge pipe 512 is the baffle 507 pushed open by the guide plate 1 509 and the guide plate 3 513, allowing the granules to freely enter and exit. This ensures that the opening is only at a designated position, guaranteeing the accuracy of the feeding.
[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
