[0032] Reference Figure 1~Figure 4 , which is the first embodiment of the utility model, proposes

[0033] A blocking-proof feeding device includes: a first main body 100, having a feed discharge channel 110; a second main body 200, having a conveying channel 210, the feed discharge channel 110 being connected to the conveying channel 210; a fixing member 300, arranged in the feed discharge channel 110, the fixing member 300 and the first main body 100 forming a feed discharge port 310, the fixing member 300 being used to guide materials, and the feed discharge port 310 being used to convey materials to the conveying channel 210.

[0034] In this embodiment, the first body 100 is made of high-strength wear-resistant material and is in the shape of a vertically placed cylindrical barrel, with the bottom slightly smaller than the top to facilitate the natural sliding of the material. A straight-line feed channel 110 is opened in the center of the barrel. The second body 200 is located immediately below the first body 100 and is made of the same or compatible material as the first body 100. It is in the form of a horizontal pipe structure, and the inside of the pipe constitutes a conveying channel 210. The conveying channel 210 is connected to the feed channel 110 of the first body 100 at the bottom through a smoothly transitioned interface to ensure that the material can be seamlessly transitioned to the conveying channel 210 for ventilation during the conveying process to convey the material. The fixing part 300 is installed in the feed channel 110 of the first body 100, and the material is selected from a wear-resistant material with a low friction coefficient, such as stainless steel. The fixing part 300 extends from the feed channel 110 to a position close to the connection to the conveying channel 210. The design of the fixing part 300 not only guides the material to slide down along a specific path, but also reduces the friction of the material in contact with it through its surface treatment, further promoting the smooth fall of the material. The fixing part 300 is used to increase the wind pressure and wind speed, thereby improving the conveying efficiency; the fixing part 300 and the first body 100 can be fixed by bolts or welding to ensure that the structure is stable and reliable. The discharge port 310 is located at the connection between the first body 100 and the second body 200, and is formed by the natural gap formed by the fixing part 300 and the first body 100. This design ensures that after being guided by the fixing part 300, the material can be concentrated and accelerated through the narrow discharge port 310 to enter the conveying channel 210, reducing the possibility of material accumulation in this link and effectively preventing the occurrence of blockage.

[0035] Furthermore, the fixing member 300 includes: a first guide plate 320, which is tiltedly arranged in the discharge channel 110; a second guide plate 330, which is slidably arranged on the first guide plate 320. After the second guide plate 330 slides, the second guide plate 330 and the discharge channel 110 form a discharge port 310, and the second guide plate 330 is used to push the material.

[0036] In this embodiment, the first guide plate 320 is made of a material with high strength and certain flexibility, and is tilted inside the material discharge channel 110. The tilt angle ensures that the material slides smoothly along the preset path. The first guide plate 320 is fixed to a side wall of the material discharge channel 110, and is firmly connected by bolts or welding to ensure stability and non-displacement during long-term use. The second guide plate 330 is designed as a flat plate structure that can slide along the surface of the first guide plate 320. The material is selected to be a lightweight and wear-resistant alloy or engineering plastic to ensure that it can slide freely on the first guide plate 320 without getting stuck. This design allows the size of the material discharge port 310 to be flexibly adjusted according to actual needs, thereby controlling the material flow rate and speed to adapt to different working conditions. When the second guide plate 330 slides to the bottom of the material discharge channel 110, it forms a variable-sized material discharge port 310 together with the first guide plate 320. The subtlety of this design is that by adjusting the position of the second guide plate 330, the speed and amount of the material passing through the material discharge port 310 can be controlled to prevent air backflow or small particle material backflow, further enhancing the anti-blocking effect. In addition to being an adjustment component of the discharge port 310, the second guide plate 330 also has the function of pushing materials. When materials are accumulated in the conveying channel 210, the second guide plate 330 is slid toward the accumulated materials through an external driving mechanism (such as electric, pneumatic or manual), which directly acts on the material layer to push the accumulated materials, effectively solving the problem of local blockage caused by excessive humidity or strong viscosity of the materials. In summary, the design of the fixing member 300 in this embodiment not only optimizes the guiding and discharge process of the materials through the coordinated use of the first guide plate 320 and the second guide plate 330, but also realizes the dynamic adjustment of the size of the discharge port 310 and the effective pushing of the materials.

[0037] Furthermore, the first guide plate 320 has a plurality of first through holes 321 , and the second guide plate 330 has a plurality of second through holes 331 . After the second guide plate 330 slides, the first through holes 321 and the second through holes 331 overlap or communicate with each other.

[0038] In this embodiment, a plurality of evenly distributed first through holes 321 are arranged on the surface of the first guide plate 320. These through holes are designed to be circular, rectangular or other suitable shapes according to actual needs, and the size and layout take into account the material characteristics and flow control requirements. The setting of the first through hole 321 can not only allow part of the material to pass directly, but also provide a multi-path falling option for the material when the second guide plate 330 is not completely closed, so as to achieve the preliminary dispersion of the material. The second guide plate 330 is also designed with a plurality of second through holes 331, and the second through holes 331 match the first through holes 321 in quantity, shape and size. The layout of the second through holes 331 ensures that an effective material flow path can be formed when the two slide against each other and finally align. When the first through hole 321 and the second through hole 331 are closed, the material can slide down along the first guide plate 320. This design can adjust the position of the second guide plate 330 according to production needs, and then adjust the number and position of the through hole alignment, so as to flexibly control the material flow to multiple different conveying channels 210 or distribute it to different processing links according to a specific ratio, thereby improving the flexibility and efficiency of system processing.

[0039] Furthermore, the first guide plate 320 has a plurality of grooves 322 , and the second guide plate 330 has a plurality of protrusions 332 , and the protrusions 332 are slidably disposed in the grooves 322 .

[0040] In this embodiment, the depth and width of the groove 322 on the surface of the first guide plate 320 are customized according to the size of the protrusion 332 of the second guide plate 330 to ensure a close fit between the two. The protrusion 332 is designed to have a smooth surface to ensure the stability and accuracy of the second guide plate 330 when sliding in the groove 322 of the first guide plate 320. In order to enhance the diversion effect, the present solution can also design a plurality of first through holes 321 on the groove 322, and also design a second through hole 331 on the protrusion 332.

[0041] Furthermore, it also includes: a screw rod 400, which is rotatably disposed on the second guide plate 330 and has a thread disposed on the first body 100, and the screw rod 400 drives the second guide plate 330 to slide after rotating.

[0042] In this embodiment, a sturdy and durable screw 400 is installed on one side edge of the second guide plate 330, and the axis of the screw 400 is parallel to the sliding direction of the second guide plate 330. The inner surface of the first body 100 is processed with a thread structure matching the screw 400, corresponding to the position of the rotation path of the screw 400. When the screw 400 rotates, it can drive the second guide plate 330 to move up and down along its sliding track smoothly and efficiently. One end of the screw 400 is connected to a motor or other power source, and the forward and reverse rotation of the motor is controlled by the command of the control system (such as PLC or microprocessor), so as to realize the rotation of the screw 400. According to the preset program or real-time feedback signal of the control system, the up and down sliding position of the second guide plate 330 can be accurately controlled to achieve automatic adjustment of the size of the discharge port 310 and the material flow rate. The operator or system only needs to issue a simple control command, and the motor drives the screw 400 to rotate, and the precise displacement of the second guide plate 330 is realized through the engagement of the thread with the screw 400. The threaded matching structure does not affect the sealing effect of the discharge channel 110. This design greatly improves the convenience and response speed of operation, and can significantly improve production efficiency and flexibility of process control.

[0043] Furthermore, the first guide plate 320 and the second guide plate 330 are both integrated structures.

[0044] In this embodiment, the first guide plate 320 is designed as an independent one-piece unit, which is manufactured by injection molding, casting or precision machining to ensure a compact structure and high strength. This structure is easy to install in the material discharge channel 110 and provides a stable guide path for the material. The second guide plate 330 is also designed as an independent one-piece structure, including a protrusion 332. The material and manufacturing process of the second guide plate 330 also focus on strength and wear resistance, ensuring stability and long life during the sliding process.

[0045] Furthermore, it also includes: a detection member 500, which is arranged on the first body 100, and the detection member 500 is used to detect material accumulation.

[0046] In this embodiment, in order to further enhance the intelligent monitoring capability of the anti-blocking feeding device, the detection member 500 is installed at an appropriate position of the first body 100, usually a key area where materials are easily accumulated or need to be monitored in real time. This may involve multiple detection points to ensure full coverage and accurate reflection of the material status in the feeding channel 110. After detecting a blockage, a signal is sent to the feeding member to prevent the material from entering the feeding channel 110.

[0047] Furthermore, it also includes: a baffle 600, which is arranged on the second guide plate 330, and the baffle 600 is used for guiding wind.

[0048] In this embodiment, in order to prevent the wind in the conveying channel 210 from being blown out from the first through hole 321 and the second through hole 331 and entering the unloading channel 110, a baffle 600 is designed on the second guide plate 330. Due to the blocking effect of the baffle 600, the conveying efficiency in the conveying channel 210 is higher.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
