Description

Technical Field

[0001] This utility model relates to the field of hopper technology, specifically to an adjustable flow rate plastic granule anti-accumulation hopper. Background Technology

[0002] A hopper is a device used to store and guide materials from a high place to a low place or into specific equipment. It is typically installed at the front end of a material conveying system, serving to temporarily store materials, control material flow, and guide material direction. The hopper is a simple and practical material conveying equipment component widely used in various industries.

[0003] When using a hopper to process plastic granules, if the plastic granules are irregularly shaped or too large, they are prone to accumulating at the discharge port, forming a "natural arch bridge" that obstructs material flow. In addition, plastic granules absorb moisture in humid environments, causing them to soften and increasing friction with the hopper wall, making discharge difficult and leading to accumulation and blockage, which affects the discharge effect. Utility Model Content

[0004] The purpose of this utility model is to provide an adjustable flow rate plastic granule anti-accumulation hopper, including a support frame, a hopper inside the support frame, a guide component for preventing plastic granule material accumulation on the inner wall of the hopper, the guide component including an adjusting valve at one end of the hopper, guide plates and circulation grooves on both sides of the inner wall of the hopper, a spring shaft in the middle section of the guide plate, pulleys at both ends inside the circulation groove, a contact belt on the outside of the pulleys, and multiple friction pads on the outer wall of the contact belt;

[0005] The inner wall of the circulation tank is provided with a drive roller, and the outer wall of the drive roller is provided with multiple cavities, each of which is provided with a protrusion and a pressure plate.

[0006] Preferably, the hopper is located on the inner wall of the support frame and is connected to the support frame by bolts. The regulating valve is located at the discharge end of the hopper and can control the opening range of the regulating valve and adjust the feeding speed.

[0007] Preferably, the guide plate has a segmented structure, with one end connected to the inner wall of the hopper and the other end at an inclined angle and placed above the circulation trough. The two segmented ends of the guide plate are rotatably connected by a spring shaft.

[0008] Preferably, the two pulleys are located at both ends inside the circulation groove and are rotatably connected to the inner wall of the circulation groove through bearings. The contact belt is sleeved on the outside of the pulley and abuts against the outer wall of the pulley, so that the contact belt can be circulated and transported in the circulation groove through the pulley.

[0009] Preferably, one side of the contact belt extends from the circulation trough into the hopper and contacts the material in the hopper. The material passing over the guide plate will cause one end of the guide plate to rotate and guide the material at an angle toward the contact belt to contact and rub against the contact belt.

[0010] Preferably, the drive roller is located in the circulation groove and is rotatably connected to the inner wall of the circulation groove via a connecting shaft. A plurality of cavities are distributed in a ring on the outer wall of the drive roller. The protrusion is located in the cavity and is rotatably connected to the inner wall of the cavity, and its other end abuts against the pressure plate, so as to solve the problems mentioned in the background art.

[0011] By adopting the above technical solution, it is possible to prevent the accumulation and blockage of plastic granules during feeding.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By installing guide plates and contact belts on the inner wall of the hopper, the contact belt can be rotated and conveyed by pulleys in the circulation trough. When the material is discharged, it falls onto the guide plates and is guided and lifted by the guide plates. When the material comes into contact with the contact belt, it falls, increasing the speed of the material's fall, effectively reducing the friction time with the hopper and reducing the chance of accumulation. At the same time, the pressure when it falls and contacts the contact belt increases, increasing the pushing force on the contact belt. This causes the contact belt to rotate due to the pressure of the fall. The rotation keeps the material in a flowing state, thus avoiding accumulation and improving the efficiency of material discharge.

[0014] 2. By installing a drive roller at the center of the circulation tank, when the material accumulates and comes into contact with the contact belt, it will press the contact belt into the circulation tank and deform and shrink, thereby contacting and pressing the protrusions on the outer wall of the drive roller. When the pressure plate inside the drive roller senses the pressure, it controls the drive roller to rotate, thereby pushing the contact belt to rotate further. This can clear the accumulated or blocked material and ensure the quality of material discharge.

[0015] This invention improves the quality of material conveying in the hopper by guiding the material and assisting in the conveying of the material by the cyclic rotation of the contact belt, and prevents the material from accumulating, thus ensuring smooth and efficient material discharge.

[0021] 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.

[0022] Please see Figures 1-3 An adjustable flow rate plastic granule anti-accumulation hopper includes a support frame 1, with a hopper 2 inside the support frame 1 for temporary storage and guiding of the material during discharge. The inner wall of the hopper 2 is equipped with a guiding component to prevent the accumulation of plastic granules. The guiding component includes a regulating valve 201 located at one end of the hopper 2, which controls the opening width to adjust the discharge flow rate. Guide plates 3 and circulation troughs 4 are located on both sides of the inner wall of the hopper 2. The guide plates 3 guide the angle of the falling material, and the circulation troughs 4 are used for... The contact belt 6 is stored and collected. A spring shaft 301 is provided in the middle section of the guide plate 3. The spring shaft 301 is used to support the two sections of the guide plate 3. When the material contacts the guide plate 3, it can press one end of the guide plate 3 to rotate and tilt. Both ends of the circulation trough 4 are provided with pulleys 5. The pulleys 5 can support the contact belt 6, thereby maintaining the structure of the contact belt 6. The contact belt 6 is provided outside the pulleys 5. The two ends of the contact belt 6 are annular structures, which can cooperate with the pulleys 5 to transport in the circulation trough 4. Multiple friction pads 601 are provided on the outer wall of the contact belt 6.

[0023] The hopper 2 is located on the inner wall of the support frame 1 and is connected to the support frame 1 by bolts. The regulating valve 201 is located at the discharge end of the hopper 2 and can control the opening range of the regulating valve 201 and adjust the feeding speed. The guide plate 3 has a segmented structure, with one end connected to the inner wall of the hopper 2 and the other end at an inclined angle and placed above the circulation trough 4. The two segmented ends of the guide plate 3 are rotatably connected by a spring shaft 301. One side of the contact belt 6 extends from the circulation trough 4 into the hopper 2 and contacts the material in the hopper 2. The material passing on the guide plate 3 will cause one end of the guide plate 3 to rotate and guide the material angle toward the contact belt 6 to contact and rub against the contact belt 6.

[0024] Specifically, when the material falls in the hopper 2, the material at the edge will contact the guide plate 3 and be guided by the guide plate 3 to adjust its falling angle. The material is pressed to tilt the guide plate 3 and guide the material to the contact belt 6. The friction between the material and the contact belt 6, combined with the impact force during the fall, works with the pulley 5 to drive the contact belt 6 to be conveyed in the circulation trough 4. The rotation of the contact belt 6, in conjunction with the guide plate 3, can increase the speed of the material falling, thereby breaking up any clumps of material, effectively preventing material accumulation, and ensuring the quality of the falling material.

[0025] Please see Figure 2 and Figure 4 The inner wall of the circulation trough 4 is provided with a drive roller 7. When the connecting shaft inside the drive roller 7 is energized, it can generate driving force to make the drive roller 7 rotate. The outer wall of the drive roller 7 is provided with multiple cavities 8 for storing the protrusions 801 and pressure plates 802 and for positioning the protrusions 801 at an angle. The multiple cavities 8 are provided with protrusions 801 and pressure plates 802. The protrusions 801 can increase the friction between the drive roller 7 and the contact belt 6, so that the drive roller 7 can drive the contact belt 6 to convey. The pressure plates 802 can detect the contact pressure when the contact belt 6 contacts the drive roller 7.

[0026] Two pulleys 5 are located at both ends inside the circulation groove 4, and are rotatably connected to the inner wall of the circulation groove 4 through bearings. The contact belt 6 is sleeved on the outside of the pulleys 5 and abuts against the outer wall of the pulleys 5. The contact belt 6 can be circulated and conveyed in the circulation groove 4 through the pulleys 5. The drive roller 7 is located inside the circulation groove 4 and is rotatably connected to the inner wall of the circulation groove 4 through a connecting shaft. Multiple cavities 8 are distributed in a ring on the outer wall of the drive roller 7. The protrusion 801 is located inside the cavity 8 and is rotatably connected to the inner wall of the cavity 8, and its other end abuts against the pressure plate 802.

[0027] Specifically, when material accumulates in hopper 2 and is located in the contact belt 6 area, the contact belt 6 is made of flexible material, and the drive roller 7 does not normally contact the contact belt 6. Therefore, the support force in the central area of ​​the contact belt 6 is relatively weak. When the material accumulates, it can squeeze the contact belt 6, causing the contact belt 6 to contract and contact the protrusion 801 on the outer wall of the drive roller 7. At the same time, the pressing force is transmitted to the pressure plate 802 through the protrusion 801. When the pressure plate 802 detects the pressure, it controls the connecting shaft to activate, causing the drive roller 7 to rotate in the circulation groove 4. This drives the contact belt 6 to convey the material. The contact belt 6 rubs against the material during conveying, thereby breaking the structure of the material accumulation and clearing the blockage caused by the accumulation. This ensures the quality and efficiency of material feeding from hopper 2.
