Description

Technical Field

[0001] This utility model belongs to the field of industrial equipment technology, and more specifically, it relates to a feeding mechanism for preventing material bridging. Background Technology

[0002] When producing flame-retardant wood-like foamed materials, a feeder and a mixing device are required. The material of the foamed material enters the feeder through the material feeding mechanism of the feeder. The feeder controls the material to reach the mixing device for mixing, thereby realizing the processing of flame-retardant wood-like foamed materials.

[0003] According to CN202322907043.5, this utility model relates to the technical field of foam material processing equipment and discloses a feeding and discharging device for a foam material reaction tank. Its structure includes a reaction tank, an extraction and discharging device, and a heating device. The beneficial effects of this utility model are as follows: The foam material and aqueous solution are extracted by driving the foam feeding pipe and water inlet pipe through a control valve and discharged into the reaction tank through a diversion pipe for mixing. The diversion pipe separates the foam material and aqueous solution, ensuring sufficient contact between them during mixing within the reaction tank. Then, a control switch controls the rotation of the ball in the one-way ball valve to the discharge state. A solenoid valve drives the extraction pipe to extract the foam material that has completed the reaction within the reaction tank. This avoids the conventional method of filling the reaction tank with foam material bottles and discharging by pressing the bottles. The extraction method allows for faster feeding and discharging of the foam material, improving work efficiency.

[0004] Based on the above, existing feeding mechanisms generally insert materials into the feeder through the inlet structure. Since some of the foaming material is in powder form, bridging is likely to occur after the powder enters the feeder. Bridging can lead to unstable material feeding, with varying amounts, and in severe cases, the material may clump together too much or too large, causing the material to get stuck at the outlet and interrupting production. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a feeding mechanism to prevent material bridging. This addresses the issue that existing feeding mechanisms typically insert materials into the feeder through an inlet structure. Since some foaming materials are powdery, bridging easily occurs after the powder enters the feeder. Bridging leads to unstable material feeding, with varying amounts, and in severe cases, excessive or large material agglomerates, causing material to jam at the outlet and disrupting production.

[0006] The purpose and effect of this utility model's feeding mechanism for preventing material bridging are achieved by the following specific technical means:

[0007] A feeding mechanism for preventing material bridging includes a feeding body, a feeding pipe, a feeding funnel, a feeding outlet, a feeding auger, a sealing plate, an anti-bridging mechanism, and a feeding protection mechanism. The feeding pipe is slidably connected to the upper side inside the feeding body. The feeding funnel is fixedly connected to the upper end face of the feeding pipe and slides on the upper end face of the feeding body. The feeding outlet is fixedly connected to the right side of the lower end face of the feeding body. The feeding auger is rotatably connected to the inner end face of the feeding body. The sealing plate rotates on the upper side of the inner end face of the feeding funnel. The anti-bridging mechanism is disposed inside the feeding body. The feeding protection mechanism is disposed on the upper side inside the feeding funnel.

[0008] Furthermore, the anti-bridging mechanism includes a feeding motor; the feeding motor is fixedly connected to the middle position of the left end face of the feeding body, and the feeding motor shaft and the feeding auger shaft are coaxially fixedly connected.

[0009] Furthermore, the anti-bridging mechanism also includes: a feeding pulley, a feeding drive belt, and an anti-bridging pulley; the feeding pulley is coaxially and fixedly connected to the left side of the feeding auger shaft; the anti-bridging pulley is rotatably connected to the left side inside the feeding body; and the feeding drive belt is drivingly connected to the outer end faces of the feeding pulley and the anti-bridging pulley.

[0010] Furthermore, the anti-bridging mechanism also includes: an anti-rotating shaft, an anti-large bevel gear, and a displacement bevel gear; the anti-rotating shaft is rotatably connected to the left side inside the feeding body, and the left side of the anti-rotating shaft and the anti-pulley are coaxially and fixedly connected; the anti-large bevel gear is coaxially and fixedly connected to the right side of the anti-rotating shaft; the displacement bevel gear is rotatably connected to the left side inside the feeding body, and the meshing of the anti-large bevel gear and the displacement bevel gear together form a bevel gear transmission mechanism.

[0011] Furthermore, the anti-bridging mechanism also includes: a displacement cam and a first connecting block; the displacement cam is fixedly connected to the rear side of the displacement bevel gear, and the displacement cam is rotatably connected to the left side inside the feeding body; the first connecting block is fixedly connected to the middle position of the left end face of the feeding pipe, the first connecting block is slidably connected to the left side inside the feeding body, and the first connecting block is slidably connected to the right side of the displacement cam.

[0012] Furthermore, the anti-bridging mechanism also includes: a second connecting block and a displacement spring; the second connecting block is fixedly connected to the middle position of the right end face of the feed pipe, and the second connecting block is slidably connected to the middle position inside the feeding body; the displacement spring is fixedly connected to the middle position inside the feeding body, and the second connecting block and the displacement spring are elastically connected.

[0013] Furthermore, the feeding protection mechanism includes: a sealing shaft and a sealing torsion spring; the sealing shaft is rotatably connected to the upper side inside the feeding funnel, and the middle position of the sealing shaft is fixedly connected to the sealing guard plate; the sealing torsion spring is fixedly connected to the upper side inside the feeding funnel, and the sealing shaft and the sealing torsion spring are elastically connected.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention employs an anti-bridging mechanism. When powdered material is added to the feed pipe and feed hopper, the feeding motor drives the feeding auger to rotate. The rotation of the feeding auger feeds the material, causing the feed pipe and feed hopper to vibrate. This vibration causes the material inside the feed pipe and feed hopper to vibrate, thereby quickly discharging the material from the feed pipe and feed hopper. This avoids bridging issues caused by material bridging inside the feed pipe and feed hopper, improving material discharge efficiency and reducing the occurrence of unexpected material discharge situations.

[0016] This utility model employs a feeding protection mechanism, in which a sealing torsion spring drives a sealing plate to rotate and protect the inner end face of the feeding funnel. This prevents impurities from entering the feeding funnel and affecting the quality of the flame-retardant wood-like foam material, thus ensuring the feeding funnel is sealed.
