[0003] When the material enters the hopper through the feed port, it generates an impact force that impacts and wears the inner wall of the vacuum suction machine. This impact force mainly comes from the high speed of the material during flow, which increases the impact force and causes greater wear on the inner wall. Therefore, a vacuum suction machine feed anti-collision structure is needed. Utility Model Content

[0021] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] A vacuum conveyor is a device that uses vacuum to transport granules, powders, or other materials from one location to another. It is widely used in industries such as plastics, chemicals, and food. Its basic operating principle is to use a vacuum pump to generate negative pressure, creating suction that draws the material into a suction pipe and delivers it to the target location. During use, the impact force of certain materials and the abrasive properties of the materials themselves can cause impact and wear on the inner wall of the vacuum conveyor's barrel. Therefore, a vacuum conveyor feeder anti-collision mechanism is required.

[0023] In the process of the existing device, when the material enters the hopper through the feed port, it will generate impact force, which will cause impact and wear on the inner wall of the vacuum suction machine. This impact force mainly comes from the high speed of the material during the flow process, which will increase the impact force and cause greater wear on the inner wall. Figures 1-4 This embodiment provides a feeding anti-collision structure for a vacuum suction machine, including a hopper 1, a feeding pipe 2 fixedly connected to the outside of the hopper 1, and a vacuum pump 3 fixedly connected to the top of the hopper 1. When the vacuum pump 3 is turned on, the gas in the hopper 1 is extracted, and the material enters the hopper 1 through the feeding pipe 2.

[0024] refer to Figure 2-Figure 3As shown in the figure, in the process of the material entering the hopper through the feed port of the existing device, an impact force is generated, which causes impact and wear on the inner wall of the hopper of the vacuum suction machine. This impact force mainly comes from the high speed of the material during the flow process, which increases the impact force and causes greater wear on the inner wall. In order to improve the anti-collision performance of the vacuum suction machine and extend the service life of the equipment, the following configuration is made: the interior of the hopper 1 is provided with an anti-collision component 5 to reduce the impact force of the logistics. The anti-collision component 5 includes a rotor 51 rotating in the hopper 1. A plurality of impact-reducing blades 52 are fixed to the outer ring of the rotor 51 at equal intervals. The end face of the feed pipe 2 is fixedly connected to a meander pipe 4 to optimize the flow path of the material and play a role in guiding the flow direction of the logistics, ensuring that the logistics rush towards the impact-reducing blades 52 to rotate the rotor 51. The inhaled logistics rushes towards the impact-reducing blades 52, driving the rotor 51 to rotate. The impact-reducing blades 52 guide the flow direction of the logistics, allowing it to enter the hopper 1 more smoothly, avoiding turbulence or sudden changes in the logistics within the hopper 1. This guiding effect helps to reduce the impact speed of the logistics and further reduce the wear on the hopper 1. Each of the impact-reducing blades 52 is fitted with a buffer plate 53. This internal component is designed to limit the sliding freedom of the buffer plate 53 within the blade 52. The buffer plate 53 has a horizontal rail formed on its inner wall. A slider is fixedly connected to the outer wall of the buffer plate 53, which slides laterally along the inner wall of the horizontal rail. A buffer pad 54 is fixed to one side of the buffer plate 53. The buffer pad 54 is made of, but not limited to, polyurethane or rubber, materials with excellent elasticity and energy absorption. When the material contacts the buffer pad 54, it deforms, absorbing some of the kinetic energy and reducing the impact force. This elastic property cushions the collision of the material and reduces direct impact on the inner wall of the equipment. A buffer spring 55 is fixed to the other side of the buffer plate 53. When the material impacts the buffer pad 54, the pressure generated pushes the buffer plate 53 into the impact-reducing blade 52, squeezing the buffer spring 55. This process not only further absorbs the impact energy but also provides a rebound force, slowing the material as it passes through this section, thereby reducing its impact intensity. Through the above mechanism, the logistics flow becomes smoother and violent collision and wear are avoided.

[0025] refer to Figure 2-Figure 4As shown, due to the different physical properties of different materials, materials with higher density will generate greater impact force when flowing, which can easily cause damage to the equipment. In order to optimize the anti-collision effect, the flow rate in the feed pipe is dynamically adjusted according to the material characteristics to ensure the smooth flow of the material during the transportation process. The following settings are specially made. The interior of the impact reduction leaf 52 is provided with a control device 56 for automatically adjusting the flow rate of the material in the feed pipe 2 according to the impact force of the material. The control device 56 includes a pressure sensor 561 fixed in the impact reduction leaf 52 and an electric valve 562 fixed outside the feed pipe 2, wherein the pressure sensor 561 is in contact with the buffer plate 53. Due to the different physical properties of different materials, the real-time detection and adjustment mechanism enables the system to adapt to various materials to ensure that it is always In the best working state, the pressure sensor 561 can detect the material pressure in real time. This pressure value is directly related to the flow rate and impact force of the material. By monitoring these data, the movement state of the material can be understood in a timely manner. When the pressure sensor 561 detects that the impact force exceeds the preset threshold, the information can be fed back to the external controller. The controller determines whether the current flow rate is appropriate based on these real-time data. The external controller changes the flow rate in the feed pipe 2 by adjusting the working parameters of the electric valve 562. This automatic adjustment mechanism can ensure that the system always maintains the best feeding state under different materials or working conditions. By reducing the flow rate, the impact force of the material on the suction pad 54 can be reduced, thereby effectively reducing wear and damage to the equipment. On the contrary, when the material flow is relatively stable, the flow rate can be appropriately increased to improve work efficiency. This feedback control system can not only achieve real-time adjustment, but also maintain the stability and reliability of the equipment during long-term operation and reduce the failure rate.

[0026] refer to Figure 2-Figure 3 As shown, an arc-shaped wear-reducing plate 6 is fixed to the inner wall of the hopper 1 to prevent the residual force of the logistics from wearing the inner wall of the hopper 1. The impact-reducing blades 52 guide the logistics to be discharged to the arc-shaped wear-reducing plate 6 with lower impact intensity, so as to reduce the direct contact between the material and the wall surface, reduce the force of direct impact, and thus reduce the risk of wear, which can effectively extend the service life of the hopper 1 and maintain its performance.

[0027] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
