Furthermore, traditional pillow core filling feeding structures typically use a single storage bin for material storage. When filling different types of pillow core materials, it is necessary to frequently change the storage bin or clean it, which is cumbersome and inefficient. At the same time, it is also easy to cause cross-contamination between different materials, affecting the quality of the pillow core.

[0004] Therefore, a pillow core processing and filling feeding structure is proposed. Utility Model Content

This not only leads to inconsistent weights of finished pillow cores, affecting standardized production, but also may cause material waste and increase production costs. Furthermore, traditional pillow core filling feeding structures typically use a single storage bin for material storage. When filling different types of pillow core materials, it is necessary to frequently change the storage bin or clean it, which is cumbersome and inefficient.

[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A pillow core processing filling feeding structure includes a support 1. A first horizontal plate 2 and a second horizontal plate 3 are fixedly connected inside the support 1. A feeding component 4 is fixedly connected inside the first horizontal plate 2. The feeding component 4 includes a plurality of storage bins 401. A weighing component 5 is fixedly connected inside the second horizontal plate 3 and the weighing component 5 is used in conjunction with the storage bins 401.

[0027] The weighing assembly 5 includes a fixed cylinder 501, which is fixedly connected to the inside of the second horizontal plate 3. A measuring cylinder 502 is provided inside the fixed cylinder 501, and a drop valve is provided inside the bottom of the measuring cylinder 502. Vertical grooves 503 are provided on both sides of the inner wall of the fixed cylinder 501. A weighing sensor 504 is fixedly connected to the bottom of the inner wall of the vertical groove 503. A pressing block 505 is fixedly connected to both sides of the surface of the measuring cylinder 502. The pressing block 505 is slidably connected inside the vertical groove 503 and works in conjunction with the weighing sensor 504.

[0028] In this embodiment: by setting up the weighing component 5, the fixed cylinder 501 serves as the main frame of the weighing component 5, providing support and protection for the metering cylinder 502. Simultaneously, it connects to the storage silo 401 via the connecting pipe 8, ensuring that the material can smoothly fall into the metering cylinder 502. The metering cylinder 502 can directly receive the filling material falling from the storage silo 401, and the material release and filling are controlled by a drop valve at the bottom. The drop valve is located at the bottom of the metering cylinder 502. When the weighing sensor 504 detects that the material has reached the set weight, the PLC controller 10 triggers the drop valve to open, completing a single cycle. The filling process involves a vertical groove 503 providing a vertical sliding track for the extrusion block 505. As the material in the metering cylinder 502 increases, the extrusion block 505 presses down on the weighing sensor 504. The weighing sensor 504 can monitor the pressure transmitted by the extrusion block 505 in real time, converting the physical signal into an electrical signal and transmitting it to the PLC controller 10. This allows for accurate weighing of the material in the metering cylinder 502. The cooperation between the extrusion block 505 and the vertical groove 503 ensures that the pressure of the metering cylinder 502 acts vertically on the weighing sensor 504, reducing lateral force interference and improving weight detection accuracy.

[0029] Specifically, such as Figure 3 As shown, an axial flow fan 402 is fixedly connected to the top of the bracket 1. The output end of the axial flow fan 402 is fixedly connected to a guide pipe 403. The end of the guide pipe 403 away from the axial flow fan 402 passes through the bracket 1 and is fixedly connected to a horizontal pipe 404.

[0030] Specifically, such as Figure 3 As shown, the horizontal pipe 404 is set above the storage bin 401 and both ends of the horizontal pipe 404 are fixedly connected to the inner wall of the support 1. The bottom of the surface of the horizontal pipe 404 is fixedly connected to the branch pipe 405. The number of branch pipes 405 is set to multiple and they are used in conjunction with the storage bin 401.

[0031] Specifically, such as Figure 3 As shown, the bottom end of the branch pipe 405 penetrates through the storage silo 401 and is fixedly connected to it, and one end of the branch pipe 405 located inside the storage silo 401 is fixedly connected to the ventilation hood 406, and the ventilation hood 406 is located at the top inside the storage silo 401.

[0032] Specifically, such as Figure 4 As shown, the top of the storage silo 401 is fixedly connected to a feeding pipe 6, and the top of the feeding pipe 6 is threadedly connected to a sealing cap 7.

[0033] In this embodiment: With the above configuration, the axial flow fan 402 serves as a power source, generating high-speed airflow. This airflow transports the filling material from the storage silo 401 to the metering cylinder 502. The air duct 403 connects the axial flow fan 402 to the horizontal pipe 404, guiding the airflow generated by the axial flow fan 402 to the horizontal pipe 404. The horizontal pipe 404, as the main pipe, collects and distributes the airflow to each branch pipe 405, enabling simultaneous feeding from multiple storage silos 401. The shut-off valve 9 can individually control the airflow in each branch pipe 405, thus achieving… The independent feeding or shutdown of a single storage silo 401 is achieved by branch pipe 405 diverting the airflow from horizontal pipe 404 to each storage silo 401, forming an independent feeding channel. The air diffuser 406 diffuses the airflow delivered by branch pipe 405, forming an umbrella-shaped coverage area, which can quickly blow the material in the storage silo 401 into the metering cylinder 502. The feeding pipe 6 is the material inlet, and the filling material can be added to the system manually or mechanically. The sealing cover 7 can prevent the material from getting damp and dust from entering, ensuring the cleanliness of the material inside the storage silo 401.

[0034] Specifically, such as Figure 5 As shown, the bottom of the storage silo 401 is fixedly connected to a connecting pipe 8. Both the connecting pipe 8 and the transverse pipe 404 are equipped with shut-off valves 9, and the shut-off valve 9 inside the transverse pipe 404 is used in conjunction with the branch pipe 405.

[0035] Specifically, such as Figure 1 As shown, a PLC controller 10 is fixedly installed on the left side of the bracket 1. The drop valve, the weighing sensor 504, the axial flow fan 402, and the shut-off valve 9 are all electrically connected to the PLC controller 10.

[0036] In this embodiment: With the above settings, the connecting pipe 8 is the connecting channel between the storage bin 401 and the metering cylinder 502, which can guide the material from the storage bin 401 to fall into the metering cylinder 502. The shut-off valve 9 inside the connecting pipe 8 can control the material flow rate from the storage bin 401 to the metering cylinder 502. When the weighing sensor 504 detects that the material in the metering cylinder 502 is close to the target weight, the PLC controller 10 can close the shut-off valve 9 inside the connecting pipe 8 in advance to prevent the material from continuing to fall during the metering process and causing overweight. The shut-off valve 9 inside the horizontal pipe 404 can open or close the feeding of a specific storage bin 401 individually, which improves the flexibility of use. The PLC controller 10 can read the weight signal of the weighing sensor 504 in real time, convert the analog quantity into a digital quantity, and can automatically control the drop valve, the axial flow fan 402 and the shut-off valve 9 according to preset parameters, which improves the accuracy of use.

[0037] Specifically, such as Figure 1 As shown, the bottom of the storage bin 401 and the bottom of the metering cylinder 502 are both cone-shaped.

[0038] In this embodiment: With the above settings, the conical bottom utilizes the material's own gravity to allow the filler to slide naturally down the slope, avoiding right angles or steps that could cause material jamming, ensuring that fillers of different densities can fall smoothly, and avoiding uneven material distribution caused by local blockages.

[0039] Working principle: First, open the sealing cover 7 and pour the pillow core filling material into the storage silo 401 through the feeding pipe 6. After filling, tighten the sealing cover 7 to prevent dust from overflowing or the material from getting damp. Then, start the axial flow fan 402 through the PLC controller 10. The airflow enters the horizontal pipe 404 through the air guide pipe 403. At this time, the shut-off valve 9 in the horizontal pipe 404 opens, and the airflow enters the air diffuser 406 at the top of the storage silo 401 through the branch pipe 405. The air diffuser 406 evenly diffuses the airflow, forming downward air pressure, which pushes the filling material in the storage silo 401 to fall. The shut-off valve 9 inside the connecting pipe 8 will adjust according to the PLC controller 10. When the command is activated, the filler material enters the weighing component 5 below under the combined action of gravity and airflow. After the filler material falls into the metering cylinder 502 through the connecting pipe 8, the extrusion blocks 505 on both sides of the metering cylinder 502 will press down on the weighing sensor 504 as the weight of the material increases. The weighing sensor 504 will transmit the weight signal to the PLC controller 10 in real time. When the preset weight value is reached, the PLC controller 10 commands the shut-off valve 9 of the connecting pipe 8 to stop the material feeding. After the weighing is completed, the PLC controller 10 controls the drop valve to open, and the material in the metering cylinder 502 can quickly fall into the pillow core through the conical bottom.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
