Description

[Technical Field]

[0001] This invention relates to the technical field of feed hoppers, and in particular to the technical field of anti-clogging feed hoppers. [Background Technology]

[0002] Graphene is a type of poly(phosphorus) material. 2 A novel material, characterized by the close packing of hybridized carbon atoms into a single-layer two-dimensional honeycomb lattice structure, possesses excellent properties such as high electrical conductivity, thermal conductivity, specific surface area, and Young's modulus. It holds significant application potential in materials science, micro / nano fabrication, energy, biomedicine, and drug delivery, and is considered a revolutionary material for the future. Masterbatch refers to granular material produced during plastic processing by mixing various additives, fillers, and a small amount of carrier resin for ease of operation, followed by metering, mixing, melting, extrusion, and pelletizing using equipment such as extruders. Adding graphene to the raw materials for masterbatch production creates graphene masterbatch. Examples include a graphene masterbatch and its preparation method disclosed in invention patent CN109762305B, and a masterbatch and its preparation method for preparing graphene anti-electromagnetic radiation fibers disclosed in invention patent CN113717478A. Graphene masterbatch can be used to prepare artificial fibers containing graphene, such as the method for preparing graphene oxide polypropylene functional fiber disclosed in the invention patent with publication number CN107385537B.

[0003] Graphene masterbatch is typically produced using a granulator. However, existing granulators require the raw materials to be collected in a feed hopper before being injected into the granulation equipment. Unfortunately, during operation, the feed hopper continuously and in large quantities injects raw materials into the granulator, leading to blockages and ultimately affecting its production efficiency. [Summary of the Invention]

[0004] The purpose of this invention is to solve the problems in the prior art by proposing an anti-clogging material feed hopper. The opening degree of the discharge port can be adjusted to control the discharge speed, and the up-and-down movement cycle of the guide sleeve can be adjusted to control the discharge cycle, effectively avoiding the occurrence of blockage in the granulator.

[0005] To achieve the above objectives, this invention proposes an anti-clogging material feeding hopper, comprising a hopper, a discharging mechanism, and a controller. The lower end of the hopper wall is sloping towards the center, forming a narrowing section. A discharging port is provided above the narrowing section, connecting the inner cavity of the hopper to the outside. The discharging mechanism includes a driver, a guide rod, a guide sleeve, and a baffle. The guide rod is located in the inner cavity of the hopper and passes horizontally through the guide hole of the guide sleeve. The guide sleeve is driven by the driver to move vertically within the inner cavity of the hopper. The baffle is fixed to one end of the guide rod and closely abuts the inner wall of the narrowing section. The baffle can move obliquely along the inner wall of the narrowing section with the guide rod to open or close the discharging port. The controller is electrically connected to the discharging mechanism.

[0006] Preferably, the actuator is a pneumatic cylinder or a hydraulic cylinder, and the actuator is located outside the container with the end of the telescopic rod extending upward into the inner cavity of the container.

[0007] Preferably, the guide rod also includes a reversing ball and fan blades. The outer wall of the guide rod is provided with a rod body spiral pattern, and the inner wall of the guide hole is provided with a hole body spiral pattern that matches the rod body spiral pattern. One end of the guide rod is rotatably connected to the baffle through the reversing ball. Several fan blades are respectively installed on the outer wall of the guide rod without the rod body spiral pattern.

[0008] Preferably, the spiral pattern on the rod is located in the middle section of the guide rod, and several fan blades are located on the left and right sides of the spiral pattern on the rod.

[0009] Preferably, the reversing ball includes a ball seat and a ball body. The ball body is rotatably connected to the ball cavity of the ball seat. The ball seat has a notch that connects the ball cavity to the outside. The ball body is partially exposed outside the ball cavity along the notch and fixed to one end of the guide rod. The ball seat is connected to the baffle.

[0010] Preferably, the ball seat includes a hemispherical cover, a limiting ring, and fasteners. The edges of the hemispherical cover and the limiting ring are respectively provided with cover flanges and ring flanges. Several corresponding cover through holes and ring through holes are provided on the cover flanges and ring flanges. The hemispherical cover and the limiting ring are spliced ​​together and surrounded by several fasteners that pass through the corresponding cover through holes and ring through holes to form a spherical cavity with a notch.

[0011] Preferably, the baffle is provided with guide portions at both ends.

[0012] Preferably, the bottom of the container is provided with an inspection port, and an inspection door is installed at the inspection port.

[0013] Preferably, the inner side of the narrowed section of the bin wall is also provided with a slide rail, and the baffle is slidably connected to the slide rail.

[0014] The beneficial effects of this invention are:

[0015] 1) The feeding mechanism is composed of a driver, guide rod, guide sleeve, and baffle. A narrowing section is set in the lower part of the bin wall. The driver can drive the guide sleeve to move vertically up and down. At the same time, it cooperates with the baffle set in close to the inner wall of the narrowing section. The guide rod moves horizontally along the guide sleeve in sync with the up and down movement of the guide sleeve. This causes the baffle to move obliquely along the inner wall of the narrowing section and open or close the feeding port. The opening degree of the feeding port can be adjusted to control the feeding speed. The up and down movement cycle of the guide sleeve can also be adjusted to control the feeding cycle. This effectively avoids the granulator blockage. The overall structure is simple, the manufacturing cost is low, and the maintenance is convenient.

[0016] 2) By adding interlocking spiral patterns on the outer wall of the guide rod and the inner wall of the guide hole of the guide sleeve, the guide rod and the baffle are rotatably connected. Several fan blades are added outside the guide rod, so that the guide rod rotates synchronously as it passes horizontally through the guide hole and the guide sleeve, thereby driving the fan blades to rotate, realizing the mixing of materials in the bin and avoiding the problem of materials clumping and blocking in the bin.

[0017] 3) The ball seat is formed by setting a hemispherical cover, a limiting ring and fasteners. The ball is rotatably connected in the ball cavity with a notch in the ball seat. Compared with the built-in bearing, the external type is simpler to assemble and requires less assembly precision between the guide rod and the baffle, which can effectively reduce production costs.

[0018] 4) By installing an inspection port with an inspection door at the bottom of the container, it is convenient for workers to inspect the components inside the container and it is easy to fully discharge the accumulated materials.

[0019] 5) By adding a slide rail to the inner side of the narrow section of the bin wall and making the baffle slide-connected to the slide rail, the smoothness of the movement of the guide rod and the baffle can be effectively improved.

[0020] The features and advantages of the present invention will be described in detail through embodiments and in conjunction with the accompanying drawings. [Attached Image Description]

Detailed Implementation Methods

[0028] See Figures 1 to 6 The present invention relates to an anti-clogging material feeding hopper, comprising a hopper 1, a discharging mechanism 2, and a controller. The lower end of the hopper wall of the hopper 1 is inclined towards the center and forms a narrowing section 11. A discharging port 12 is provided on the narrowing section 11, connecting the inner cavity of the hopper 1 with the outside. The discharging mechanism 2 includes a driver 21, a guide rod 22, a guide sleeve 23, and a baffle 24. The guide rod 22 is located in the inner cavity of the hopper 1 and passes horizontally through the guide hole of the guide sleeve 23. The guide sleeve 23 is driven by the driver 21 to move vertically within the inner cavity of the hopper 1. The baffle 24 is fixed to one end of the guide rod 22 and is in close contact with the inner wall of the narrowing section 11. The baffle 24 can move obliquely along the inner wall of the narrowing section 11 with the guide rod 22 to open or close the discharging port 12. The controller is electrically connected to the discharging mechanism 2. This structure allows for adjustment of the opening degree of the discharge port 12 to control the discharge speed, and also allows adjustment of the up-and-down movement cycle of the guide sleeve 23 to control the discharge cycle, effectively preventing clogging of the granulator. The overall structure is simple, the manufacturing cost is low, and maintenance is convenient.

[0029] The actuator 21 is a pneumatic or hydraulic cylinder, located outside the chamber 1 with the end of the telescopic rod extending upwards into the inner cavity of the chamber 1. Alternatively, the actuator 21 can also be a ball screw. Furthermore, since the actuator 21 is located outside the chamber 1 and does not come into contact with the graphene masterbatch in the chamber 1, damage to the actuator 21 is avoided, and maintenance is convenient.

[0030] It also includes a reversing ball 25 and fan blades 26. The outer wall of the guide rod 22 is provided with a rod spiral pattern 221, and the inner wall of the guide hole is provided with a hole spiral pattern 231 that matches the rod spiral pattern 221. One end of the guide rod 22 is rotatably connected to the baffle 24 through the reversing ball 25. Several fan blades 26 are respectively installed on the outer wall of the guide rod 22 without the rod spiral pattern 221. This structure allows the guide rod 22 to rotate synchronously as it passes horizontally through the guide sleeve 23 along the guide hole, thereby driving each fan blade 26 to rotate, realizing the mixing of materials in the bin 1 and avoiding the problem of material clumping and blockage in the bin 1.

[0031] The spiral pattern 221 of the rod body is located in the middle section of the guide rod 22, and several fan blades 26 are located on the left and right sides of the spiral pattern 221 of the rod body, respectively.

[0032] The reversing ball 25 includes a ball seat and a ball 253. The ball 253 is rotatably connected to the ball cavity of the ball seat. The ball seat has a notch connecting the ball cavity to the outside. The ball 253 protrudes partially from the ball cavity along the notch and is fixed to one end of the guide rod 22. The ball seat is connected to the baffle 24. Compared with built-in bearings, the external reversing ball 25 is easier to assemble and requires lower assembly precision between the guide rod 22 and the baffle 24, which can effectively reduce production costs.

[0033] The ball seat includes a hemispherical cover 251, a limiting ring 252, and fasteners 254. The edges of the hemispherical cover 251 and the limiting ring 252 are respectively provided with cover flanges and ring flanges. Several corresponding cover through holes and ring through holes are provided on the cover flanges and ring through holes. The hemispherical cover 251 and the limiting ring 252 are spliced ​​together and surrounded by several fasteners 254 that pass through the corresponding cover through holes and ring through holes to form a spherical cavity with a notch.

[0034] The baffle 24 is provided with guide portions 241 at both ends.

[0035] The bottom of the container 1 is also provided with an inspection port 13, and an inspection door 14 is installed at the inspection port 13, which not only facilitates workers to inspect the components inside the container, but also makes it easy to fully discharge the accumulated materials.

[0036] The inner side of the narrowing section 11 is also provided with a slide rail, and the baffle 24 is slidably connected to the slide rail, which can effectively improve the smoothness of the movement of the guide rod 22 and the baffle 24.

[0037] The working process of this invention:

[0038] When material needs to be discharged, the driver 21 drives the telescopic rod to extend and moves the guide sleeve 23 upward. As the guide rod 22 moves upward, it moves synchronously to the right along the guide hole of the guide sleeve 23. Meanwhile, the baffle 24 moves obliquely upward along the inner wall of the narrowing section 11 and opens the discharge port, ultimately allowing material to be discharged from... Figure 2 The status shown has switched to Figure 3 The graphene masterbatch in the bin 1 is shown in the diagram. At this time, the graphene masterbatch located in bin 1 can be discharged into the granulator along the discharge port. Furthermore, the guide rod 22 has a spiral groove 221 on its outer surface, and a spiral groove 231 on the inner wall of the guide hole of the guide sleeve. Therefore, as the guide rod 22 moves to the right along the guide hole of the guide sleeve 23, it also rotates simultaneously, thereby driving each fan blade 26 to rotate, thus stirring the graphene masterbatch in bin 1. When discharge is not required, the driver 21 drives the telescopic rod to retract until the baffle 24 closes the discharge port again, and the discharge resumes. Figure 3 The status shown has been switched back. Figure 2 The state shown.

[0039] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
