Description

Technical Field

[0001] This utility model relates to a material dispensing device for burred granular materials, belonging to the field of material batching. Background Technology

[0002] Online material sorting refers to the process of uniformly dividing particulate matter into several equal parts online. It is a common and widely used process in industrial production. Currently, a divider can simply divide particulate material into two roughly equal parts online, but the error is relatively large. If four equal parts are to be divided, a second divider is used for secondary sorting. The disadvantage is that it can only divide into an even number of parts, and the more stages there are, the larger the height space occupied by the equipment. It is not suitable for most applications. A rotary divider can also be used. The material flow rotates at a certain speed, and the circular receiving hopper below divides it into several fan-shaped receiving hoppers, from which the equal parts are led out by chutes. This method has higher sorting accuracy than a divider, but the sorting can only be done in a circular distribution. It cannot be used in situations where the sorting points must be linearly distributed.

[0003] Currently, in the production of small-particle titanium, it is necessary to roughly divide the crushed granular material into several equal parts, and the output points of these divisions must be linearly distributed and compact. However, due to the burrs around the titanium material and the mutual entanglement between particles, the division error is relatively large, and currently, no suitable equipment is available on the market. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing equipment cannot achieve linear equal division of small titanium particles, and the titanium material has burrs around its periphery, causing particles to entangle with each other, resulting in a large error in equal division.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a burr-bearing granular material dispensing device, including a rotating support roller, a dispensing cylinder and a collecting hopper. The rotating support roller is set at both ends of the dispensing cylinder and can drive the dispensing cylinder to rotate. The dispensing cylinder is inclined and the upper inclined end is connected to the feeding hopper. The inner wall of the dispensing cylinder near the feeding hopper end is arranged with turbulence columns and single-loop spiral blades at intervals. The side wall of the dispensing cylinder is arranged with several rings of dispensing ports at intervals. The collecting hopper is arranged axially at intervals below the dispensing cylinder, and each collecting hopper is correspondingly arranged below a ring of dispensing ports.

[0006] The inclination angle of the dispensing cylinder in the above-mentioned device is 1° to 15°.

[0007] In the above-mentioned device, the feed hopper is L-shaped, with one end of the feed hopper extending into the distribution cylinder, and the angle between the bend and the horizontal plane is 1° to 25°. A vibration motor is installed on the outside of the bend.

[0008] The turbulence column in the above-mentioned device is a prismatic column, and at least one such column is provided.

[0009] In the aforementioned device, the pitch of the single-threaded spiral blade is 3 to 15 times the maximum particle size of the material.

[0010] In the above-mentioned device, the dispensing port has a screw hole structure, and the dispensing port can be sealed with a plug.

[0011] In the aforementioned device, a guide hole is provided on the side wall of the discharge end of the distributing cylinder. The guide hole is arranged in a ring shape, and a collection hopper is also provided below it.

[0012] The rotating support roller in the above-mentioned device includes a power roller, a driven roller, a frame, and a mounting plate. The power roller and the driven roller are arranged in parallel on the frame. The mounting plate is arranged in the gap between the power roller and the driven roller and is connected to the feed hopper. The power roller and the driven roller are provided with flanges at both ends. The flanges at the same end of the power roller and the driven roller are tumblingly connected to the distribution cylinder.

[0013] Furthermore, the dispensing cylinder in the above device is provided with a head rolling ring and a tail rolling ring at both ends. The head rolling ring and the tail rolling ring are placed on the flange portion at the same side end as the drive cylinder and the driven cylinder, and the tail rolling ring can keep the axial position of the dispensing cylinder fixed.

[0014] Furthermore, in the above-mentioned device, an annular groove is provided on the outer side of the tail roller, and the groove is engaged with the flange of the driving roller and the driven roller.

It has the advantages of simple structure, easy maintenance, qualified accuracy, and low failure rate. This device adopts a rotary feeding cylinder, and the material flow is stable, which can meet the requirements of multiple output points arranged in a straight line. Since the material edge has burrs, the deflector column can be set to disperse and connect them, improving the material distribution accuracy. At the same time, the single-threaded spiral is used to shape the material flow, which can improve the stability of the material distribution accuracy. The rear section of the feeding cylinder is equipped with multiple rows of feeding ports.

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] like Figures 1 to 3 As shown, the present invention provides a burr-bearing granular material dispensing device, comprising a rotating support roller 3, a dispensing cylinder 2, and a collecting hopper 4. The rotating support roller 3 is disposed at both ends of the dispensing cylinder 2 and can drive the dispensing cylinder 2 to rotate. The dispensing cylinder 2 is inclined, and a feeding hopper 1 is connected to the inclined upper end. Turbulence columns 6 and single-loop spiral blades 5 are sequentially and spaced apart on the inner wall of the dispensing cylinder 2 near the feeding hopper 1. Several rings of dispensing ports 7 are spaced apart on the side wall of the dispensing cylinder 2. The collecting hopper 4 is spaced apart along the axial direction of the dispensing cylinder 2 below the dispensing cylinder 2, and each collecting hopper 4 is correspondingly disposed below a ring of dispensing ports 7. Those skilled in the art will understand that the distributing cylinder 2 of this device is inclined, and a feeding hopper 1 is provided at the upper inclined end of the distributing cylinder 2. One end of the distributing cylinder 2 is placed on a rotating support roller 3, and the other end is placed on another rotating support roller 3. Several rings of distributing ports 7 are arranged in a circular pattern on the side wall of the distributing cylinder 2, that is, several rings of distributing ports 7 are arranged axially on the side wall of the distributing cylinder 2, and each ring of distributing ports 7 is arranged circumferentially along the outer wall of the distributing cylinder 2. The corresponding collecting hopper 4 is connected below each ring of distributing ports 7. The inner wall of the front end of the distributing cylinder 2 is provided with deflecting columns 6 and single-loop spiral blades 5 at intervals for dispersing and shaping materials.

[0022] Preferably, the inclination angle of the dispensing cylinder 2 in the above-described device is 1° to 15°. Those skilled in the art will understand that the preferred inclination angle of the dispensing cylinder 2 is 1° to 15°, that is, the angle β with the horizontal plane is 1° to 15°. In practice, an angle β of 5° with the horizontal plane is preferable.

[0023] Preferably, the feed hopper 1 in the above-mentioned device is L-shaped, with one end of the feed hopper 1 extending into the distribution cylinder 2, and the angle γ between the bend and the horizontal plane is 1° to 25°. A vibrating motor is provided on the outer side of the bend. Those skilled in the art will understand that this device preferably uses an L-shaped feed hopper 1, with one end extending into the distribution cylinder 2, and the bottom of the feed hopper 1, i.e., the outer wall of the bend, forming a certain angle γ with the horizontal plane of 1° to 25°, more preferably 15°, and a vibrating motor (power: 120W) is provided to prevent material from clogging inside the feed hopper 1.

[0024] Preferably, the turbulence column 6 in the above-mentioned device is a prismatic column, and at least one is provided. Those skilled in the art will understand that the prismatic column 6 in this device, when the screen cylinder rotates at high speed, can disperse materials that are stuck together due to burrs, thus facilitating the subsequent material distribution process. Preferably, the number of turbulence columns 6 is at least one, and practically, three turbulence columns 6 are preferably arranged evenly along the circumference.

[0025] Preferably, the pitch of the single-threaded spiral blade 5 in the above-mentioned device is 3 to 15 times the maximum particle size of the material. Those skilled in the art will understand that a pitch that is too small can easily cause material blockage, while a pitch that is too large will not effectively shape the material flow. Furthermore, the better and more uniform the material flow shaping, the smaller the error during subsequent material distribution. Therefore, this device preferably uses a single-threaded spiral blade 5 with a pitch of 3 to 15 times the maximum particle size of the material, that is, a preferred pitch is 5 times the maximum particle size of the material, i.e., 100 mm.

[0026] Preferably, the feed inlet 7 in the above-mentioned device has a screw hole structure, and the feed inlet 7 can be sealed with a plug. It will be understood by those skilled in the art that the feed inlet 7 is preferably arranged in 9 rings at equal intervals along the axial direction, and each feed inlet 7 is composed of several screw holes (M24) evenly distributed along the circumference. The number of holes can be adjusted according to the required feed flow rate, and the unnecessary ones can be plugged with bolt plugs.

[0027] Preferably, the discharge end sidewall of the distributing cylinder 2 in the above-mentioned device is provided with a guide hole 8, which is arranged in an annular shape, and a collection hopper 4 is also provided below it. Those skilled in the art will understand that, in order to facilitate the discharge of remaining material in the distributing cylinder 2, this device preferably provides a guide hole 8 on the discharge end sidewall of the distributing cylinder 2. Preferably, the size of the guide hole 8 is significantly larger than that of the distributing port 7. Simultaneously, the guide hole 8 is arranged in an annular shape on the outer wall of the distributing cylinder 2, and a collection hopper 4 is also provided below it, so that remaining material can be collected through the corresponding collection hopper 4 below.

[0028] Preferably, the rotating support roller 3 in the above-mentioned device includes a driving roller 31, a driven roller 32, a frame 35, and a mounting plate 33. The driving roller 31 and the driven roller 32 are arranged parallel to each other on the frame 35. The mounting plate 33 is disposed in the gap between the driving roller 31 and the driven roller 32 and is connected to the feed hopper 1. The driving roller 31 and the driven roller 32 are provided with flange portions 34 at both ends. The flange portions 34 at the same end of the driving roller 31 and the driven roller 32 are tumblingly connected to the distributing cylinder 2. Those skilled in the art will understand that the rotating support roller 3 structure is further preferred in this device, specifically including a driving roller 31, a driven roller 32, a frame 35, and a mounting plate 33. It is supported and fixed by the frame 35, while the driving roller 31 and the driven roller 32 respectively contact the distributing cylinder 2 to realize the rotation of the distributing cylinder 2. This structure uses friction to transmit power, which is simple in structure and easy to maintain compared with gear or chain drive. The driven roller 31 is an internally powered electric roller (400W power, output speed 40r / min), with symmetrical flanges 34 at both ends. The cylindrical surface is heat-treated to a hardness of HRC60 to improve wear resistance. The driven roller 32 has bearings inside and flanges 34 at both ends. The cylindrical surface of the flanges 34 is heat-treated to a hardness of HRC60 to improve wear resistance. When the flanges 34 wear beyond the limit, the driven roller 31 can be turned around and reused, thus extending its service life. The mounting plate 33 is used to fix the feed hopper 1, and the tail rotating support roller 3 may not require the mounting plate 33.

[0029] Preferably, in the above-mentioned device, the dispensing cylinder 2 is provided with a head roller 10 and a tail roller 9 at both ends. The head roller 10 and the tail roller 9 are placed on the flange portion 34 at the same side end as the driving roller 31 and the driven roller 32, and the tail roller 9 can keep the axial position of the dispensing cylinder 2 fixed. Those skilled in the art will understand that, in order to facilitate the rotation of the dispensing cylinder 2 and the rotating support roller 3, this device preferably provides a head roller 10 and a tail roller 9 at both ends of the dispensing cylinder 2, such that the head roller 10 is placed on the rotating support roller 3, and the tail roller 9 is placed on another rotating support roller 3. The head roller 10 and the tail roller 9 are respectively placed on the flange portion 34 at the same side end of the driving roller 31 and the driven roller 32 on the corresponding side of the rotating support roller 3, which facilitates driving the dispensing cylinder 2 to rotate. At the same time, since the dispensing cylinder 2 is inclined, this device also preferably allows the tail roller 9 to keep the axial position of the dispensing cylinder 2 fixed, preventing the dispensing cylinder 2 from sliding.

[0030] Preferably, the tail roller 9 in the above-mentioned device is provided with an annular groove on its outer side, and the groove is engaged with the flange portion 34 of the driving roller 31 and the driven roller 32. Those skilled in the art will understand that, in order to achieve axial positioning of the distributing cylinder 2, this device provides an annular groove on the outer side of the tail roller 9. The groove engages the flange portion 34 at the same end of the driving roller 31 and the driven roller 32, preventing the distributing cylinder 2 from moving axially. The head roller 10, being cylindrical, is not subject to axial restriction.

[0031] Work process:

[0032] First, start the power roller 31 of the rotating support roller 3, and then start the vibrating motor on the feed hopper 1. The crushed material is introduced into the feed hopper 1, and under the action of the vibrating motor, it enters the distribution cylinder 2 along the bottom of the trough. It is dispersed by the turbulence column 6, and the unstable material flow is shaped by the single-lock spiral blade 5. Under the rotation of the inclined distribution cylinder 2, the material rolls forward in a straight line and is intercepted by the distribution ports 7 arranged in each section. A certain amount of material is then led to the next step station by its respective collection hopper 4, thus completing the equal distribution of material output points in a straight line.
