Description

Technical Field

[0001] This utility model relates to the field of PVB film processing technology, specifically to an automatic metering and feeding device. Background Technology

[0002] PVB film processing technology mainly involves the production and application of polyvinyl butyral (PVB) films. The processing steps include dissolving, mixing, coating, heating, and molding. During production, the requirements for raw material metering, proportioning, and feeding are extremely strict. Automatic metering and feeding devices ensure accurate proportioning and stable supply of raw materials, avoid human error, improve production efficiency, reduce waste, and contribute to improving the uniformity and quality of the film products.

[0003] During the design process of this utility model, the following problems were discovered in the existing technology:

[0004] Currently common feeding devices can only perform simple feeding operations. During the feeding process, it is difficult to accurately and automatically measure the required feeding amount according to different feeding needs. Usually, additional manpower and equipment are needed to repeatedly weigh the materials, which is cumbersome and labor-intensive, reducing feeding efficiency, increasing labor costs, and human intervention can easily lead to uneven material ratios, thereby affecting the processing quality and production efficiency of PVB films. Utility Model Content

[0005] The purpose of this invention is to provide an automatic metering and feeding device to solve the problem mentioned in the background art of difficulty in accurately and automatically metering the required feeding amount according to different feeding needs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic metering and feeding device, including a base frame, with several columns installed at one end of the top of the base frame, buffer springs sleeved on the top of the columns, and a placement frame sleeved on the top of the buffer springs. A feeding hopper is installed inside the placement frame, a vibrating motor is installed on one side of the bottom of the feeding hopper, and a conveying hose is installed on the other side of the bottom of the feeding hopper. Support rods are installed at both ends of the middle of the upper surface of the base frame, and a conveying cylinder is installed on the top of the support rods by screws. A drive motor is installed on one side of the conveying cylinder, and a spiral conveying rod is driven on one side of the drive motor. A discharge port is provided at one end of the bottom of the conveying cylinder. A vertical frame is installed at the top of the base frame away from the columns, a guide hopper is installed on the top of the vertical frame, a ramp hopper is installed at the bottom of the vertical frame, and a metering component is installed in the middle of the inner wall of the vertical frame.

[0007] The metering component includes a support plate installed in the middle of the inner wall of the frame. A servo motor is installed at the bottom of one side of the support plate. A drive gear is driven by one side of the servo motor. A driven gear meshes with the surface of the drive gear. A support platform is installed inside the driven gear. A groove is formed on one side of the support platform. An installation slot is installed in the middle of one side of the inner wall of the groove. A pressure sensor is installed inside the installation slot. A storage hopper is installed on one side of the pressure sensor.

[0008] More preferably, the support platform forms a rotating structure through a driven gear and a driving gear.

[0009] More preferably, the support platform forms a rotating structure through a driven gear and a driving gear.

[0010] More preferably, the internal dimensions of the mounting groove are consistent with the external dimensions of the pressure sensor.

[0011] In a further preferred embodiment, the placement rack forms a buffer structure with the uprights via a buffer spring.

[0012] More preferably, the two ends of the support platform are rotatably mounted on the inner wall of the through groove.

[0013] More preferably, the end of the conveying hose away from the feed hopper is installed at one end of the top of the conveying cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This feeding device gradually increases the weight of the hopper by injecting material into it until a pre-set threshold is reached by a pressure sensor. At this point, the servo motor automatically starts, driving the support platform and the hopper to flip to one side, thus emptying the collected material. This achieves metering and conveying of the material. Similarly, the hopper on the other side flips over to continue subsequent metering operations, achieving accurate automatic metering without additional human intervention. This avoids repeated weighing operations and human error, simplifies the feeding process, improves feeding efficiency, reduces operating costs, helps improve the uniformity of material proportions, and effectively ensures the processing quality and production efficiency of PVB films.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution for an automatic metering and feeding device: The automatic metering and feeding device includes a base frame 1, with several columns 2 installed at one end of the top of the base frame 1. A buffer spring 3 is sleeved on the top of the column 2, and a placement frame 4 is sleeved on the top of the buffer spring 3. A feeding hopper 5 is installed inside the placement frame 4. A vibration motor 6 is installed on one side of the bottom of the feeding hopper 5, and a conveying hose 7 is installed on the other side of the bottom of the feeding hopper 5. Support rods 8 are installed at both ends of the middle of the upper surface of the base frame 1. A conveying cylinder 9 is installed on the top of the support rods 8 by screws. A drive motor 10 is installed on one side of the conveying cylinder 9, and a spiral conveying rod 11 is driven on one side of the drive motor 10. A discharge port 12 is provided at one end of the bottom of the conveying cylinder 9. A frame 13 is installed at the top of the base frame 1 away from the column 2. A guide hopper 14 is installed on the top of the frame 13, and a ramp hopper 15 is installed at the bottom of the frame 13. A metering component 16 is installed in the middle of the inner wall of the frame 13.

[0023] The metering component 16 includes a support plate 1601 installed in the middle of the inner wall of the frame 13. A servo motor 1602 is installed at the bottom of one side of the support plate 1601. A drive gear 1603 is driven by one side of the servo motor 1602. A driven gear 1604 meshes with the surface of the drive gear 1603. A support platform 1605 is installed inside the driven gear 1604. A groove 1606 is opened on one side of the support platform 1605. An installation groove 1607 is installed in the middle of one side of the inner wall of the groove 1606. A pressure sensor 1608 is installed inside the installation groove 1607. A storage hopper 1609 is installed on one side of the pressure sensor 1608.

[0024] In this embodiment, as Figure 4 As shown, the support platform 1605 forms a rotating structure through the driven gear 1604 and the driving gear 1603.

[0025] In this embodiment, as Figure 4 As shown, a through groove is provided in the middle of the surface of the support plate 1601.

[0026] In this embodiment, as Figure 4 As shown, the internal dimensions of the mounting slot 1607 are consistent with the external dimensions of the pressure sensor 1608.

[0027] In this embodiment, as Figure 2 As shown, the placement rack 4 forms a buffer structure with the column 2 through the buffer spring 3.

[0028] In this embodiment, as Figure 4 As shown, the two ends of the support platform 1605 are rotatably mounted on the inner wall of the through groove.

[0029] In this embodiment, as Figure 2 As shown, the end of the conveying hose 7 away from the feed hopper 5 is installed at one end of the top of the conveying cylinder 9.

[0030] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the automatic metering and feeding device operates as follows:

[0031] First, the operator gradually injects material into the feed hopper 5. During the injection process, the vibration motor 6 is started, causing the feed hopper 5 and the material inside to shake, facilitating smooth material conveying. Simultaneously, multiple buffer springs 3 work together to effectively reduce the adverse effects of vibration on subsequent feeding operations. Next, the material is conveyed along the conveying cylinder 9 to one end inside the cylinder. Then, the drive motor 10 is started, driving the screw conveyor 11 to rotate, thereby conveying the material to the top of the inner wall of the conveying cylinder 9. Finally, the material falls out through the discharge port 12, and the scattered material is then distributed on the surface of the guide hopper 14. Guided by the feed hopper 14, the material is scattered inside the storage hopper 1609. As the weight of the material gradually accumulates, it reaches the set threshold of the pressure sensor 1608. At this time, the servo motor 1602 will be automatically started to drive the support platform 1605 and the storage hopper 1609 to flip to one side, thereby pouring out the material collected inside, thus realizing the function of material metering and discharging. Similarly, the storage hopper 1609 on the other side continues to perform material metering operations after flipping. Finally, the material will be scattered inside the ramp hopper 15 and then slide down the ramp hopper 15 for feeding, thus realizing the metering feeding operation.
