[0002] Against the backdrop of rapid development in food industrial processing and intelligent manufacturing equipment, polypropylene plastic is mainly used in the production of food bottle caps because of its heat resistance, strength and low cost.

The upper side of the rotating disk 707 is slidably connected to the bottom of the cover plate 702. A flow port 708 is provided on the rotating disk 707. The flow port 708 and one of the discharge ports 704 are located on the same axis. A toothed ring 709 is bolted to the outside of the rotating disk 707.

An isolation plate 713 is bolted to the inner wall of the feeding box 2, and a collection hopper 712 is mounted on the isolation plate 713, located below the rotating disk 707.

[0017] In specific application scenarios, the sorting and feeding module 7 is mainly suitable for the sorting and feeding stage in the sorting and feeding process. Specifically, the sorting and feeding module 7 utilizes the dispensing cylinder 701, rotating disk 707, flow port 708, and toothed ring 709 to enable the device to quickly switch between different raw material types as needed during bottle cap production. This significantly speeds up the raw material feeding waiting time, reduces process delays, accelerates production progress, and improves production efficiency. It also utilizes the weighing cylinder 717, storage tank 718, receiving cylinder 715, connecting port 716, mounting block 703, and discharge port 709. 4. It can effectively control the amount of raw materials fed in a single batch, thereby accurately controlling the total amount of raw materials fed in a single or multiple batches. This reduces the situation of feeding too much or too little raw materials, ensures the accuracy of the raw material ratio, and improves production quality. By using the notched gear 725, gear 722, transmission plate 726, and curved spring 728, the device can fix the time interval between filling and feeding the material storage tank 718, so that the material storage tank 718 has sufficient time for each loading and unloading, reducing the situation of insufficient filling of the material storage tank 718 due to time constraints.

[0018] Reference Figure 8 In a preferred embodiment, the vibratory feeding module 8 includes multiple symmetrical limiting members 801. The limiting members 801 are bolted to the opposite side of the outer surface of the storage hopper 1. The inner wall of the limiting member 801 is slidably connected to the same impact ring 802. The impact ring 802 is located outside the storage hopper 1, and two symmetrical sinking grooves 803 are opened on the upper side of the impact ring 802. The bottom inner wall of the sinking groove 803 is provided with a circular opening, and the inner wall of the circular opening is rotatably connected to a circular shaft through a bearing. The outer side of the two circular shafts is bolted to a cam 804. The end of the cam 804 away from the circular shaft is provided with a counterweight 805, and a closed frame 806 is provided above the cam 804. The bottom of the closed frame 806 is bolted to the upper side of the impact ring 802. The bottom of the impact ring 802 is bolted to two symmetrical motors 807. The output end of the motors 807 is connected to the bottom of the circular shaft on the same side through a coupling.

[0019] In specific application scenarios, the vibration feeding module 8 is mainly suitable for the vibration feeding link in the vibration feeding process. That is, the vibration feeding module 8 uses the centrifugal force generated by the rotation of the cam 804 and the counterweight 805 driven by the motor 807 to drive the impact ring 802 to impact the limiting member 801 and the storage hopper 1, thereby transmitting the vibration to the distribution cylinder 701 in the storage hopper 1, disrupting the balance formed by the accumulation of raw materials in the distribution cylinder 701. This disrupts the conical balance formed by the sinking of raw materials in the distribution cylinder 701, allowing the raw materials to continuously flow out of the distribution cylinder 701 until they all enter the feeding box 2 and are fed into the production equipment, significantly improving the continuity of raw material feeding and ensuring the smoothness of the production process.

[0020] A feeding method for producing food bottle caps, using a feeding device for producing food bottle caps as described above, includes the following steps: Step 1: Fill the different material distribution cylinders 701 with the raw materials needed for producing bottle caps in sequence; Step 2: Select a weighing cylinder 717 with a corresponding capacity for the storage tank 718 according to the planned production volume, and load the weighing cylinder 717 into the feeding box 2. Step 3: During bottle cap production, the sorting and feeding module 7 controls the feeding sequence and amount of different raw materials according to a preset program. During feeding, the vibrating feeding module 8 vibrates the storage hopper 1, allowing the raw materials in the dispensing cylinder 701 to fall smoothly. (Before bottle cap production, according to the expected production plan, the corresponding amounts of raw materials and other additives are filled into different dispensing cylinders 701. During production, according to the production process, motor 711 is started. Motor 711 drives the gear 710 meshing with the gear ring 709 to rotate, causing the rotating disk 707 to rotate, opening the flow port 708 in the closed area between the two dispensing cylinders 701.) Rotate to below the dispensing cylinder 701 where material needs to be dispensed. The material in the dispensing cylinder 701 flows into the collecting hopper 712 through the discharge port 704 and the flow port 708. The collecting hopper 712 guides the material to accumulate in the inclined groove 714 on the mounting block 703. Start the second motor 724. The second motor 724 drives the notched gear 725, which meshes with the second gear 722, to rotate. This causes the second gear 722 to rotate the connecting port 716 on the receiving cylinder 715 to an upward position, so that the material accumulated in the inclined groove 714 fills the storage hopper 718. Start the second motor 724 again. The second motor 724 drives the second gear 722 to rotate 180 degrees, from... The material storage tank 718 is rotated to a vertically downward position, allowing the raw material in the storage tank 718 to be fed into the production equipment from the feeding box 2. As the notched gear 725 rotates and disengages from gear 722, the compressed curved spring 728 pushes the transmission plate 726 to rotate the receiving cylinder 715 180 degrees in the opposite direction to return it to its original position. Under the program control of the control panel 3, the number of rotations of the notched gear 725 driven by the motor 724 is controlled to regulate the amount of raw material fed in. When it is necessary to control the single feeding amount of the weighing cylinder 717, the locking member 720 is pushed outward against the elastic force of the return spring 721, thus locking the cylinder. 720 Release the limiting position of the symmetrical measuring cylinder 717, pull the measuring cylinder 717 out of the receiving cylinder 715, and reinsert the receiving cylinder 715 with different volume storage tanks 718. When the device is feeding, the raw material in the distributing cylinder 701 will gradually enter the feeding box 2. Start the motor 807. The motor 807 drives the cam 804 to rotate in the sink trough 803. The weight of the counterweight 805 generates violent vibration as the two cams 804 rotate clockwise. Under the constraint of the limiting member 801, the impact ring 802 continuously impacts the outside of the storage hopper 1, causing the raw material attached to or accumulated on the inner wall of the distributing cylinder 701 to collapse and fall.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
