Detailed Description
The embodiment of the invention discloses a dividing machine, which is used for effectively solving the problems of difficult manufacturing and uneven dividing of the dividing machine.
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1-2, fig. 1 is a schematic diagram of a semi-sectional structure of a dividing machine according to an embodiment of the present invention; fig. 2 is a schematic bottom view of a dividing machine according to an embodiment of the present invention.
In a specific embodiment, the embodiment provides a dividing machine, and the dividing machine specifically comprises a receiving hopper 1, a material guiding pipe 2 and a driving device.
The inner side surface of the receiving hopper 1 is a conical receiving surface, a first receiving opening for collecting materials sliding down from the conical receiving surface is arranged below the receiving hopper 1, and a second receiving opening for collecting the materials falling into the conical receiving surface is partially formed in the conical receiving surface. That is, after the material is sprayed onto the conical receiving surface, the material can either slide down from the conical receiving surface to be collected by the first receiving port and flow out through the first receiving port, and on the other hand, when the material falls, the material can directly fall onto the second receiving port and flow out from the second receiving port. When the materials are uniformly sprayed on the conical material receiving port, a part of the materials flow out from the second material receiving port, a part of the materials slide into the first material receiving port from the conical material receiving port, and the amount of the materials flowing out from the second material receiving port is positively correlated according to the area of the second material receiving port, so that the method can be adopted to finish the shrinkage division. The first material receiving port and the second material receiving port can be used as a sample reserving port and the other one is used as a sample discarding port. It should be noted that in the axial direction, the uniformity of the material is generally poor, whereas in the circumferential direction the material is easily thrown uniformly, on the basis of which the second receiving opening is preferably fan-shaped, i.e. the openings on both sides in the circumferential direction are arranged along the generatrix of the conical receiving surface, whereas in the axial direction the length of the second receiving opening should be greater than the width of the material throwing surface in this direction.
The upper pipe orifice of the material guiding pipe 2 is a feed inlet, the lower pipe orifice is a discharge outlet and the discharge outlet faces the conical material receiving surface, and the driving device is used for driving the material guiding pipe 2 to rotate at a constant speed so that the discharge outlet of the material guiding pipe 2 uniformly throws materials towards the conical material receiving surface. In order to ensure that the material flows toward the lower nozzle under the action of gravity after entering from the upper nozzle of the material guiding pipe 2, the lower nozzle faces the conical material receiving surface, so that the effect of throwing the material toward the conical material receiving surface can be achieved. The specific material guiding pipe can adopt a multi-section straight pipe connecting structure, or the material guiding pipe is made to be straight pipe and is obliquely arranged. In order to achieve a better guiding effect, it is preferred that the guiding pipe 2 is an arc-shaped pipe, so that the material flows smoothly to the lower pipe orifice and is thrown out, and it should be emphasized here that the arc-shaped center of the arc-shaped pipe should be on the outer side. Preferably, an arc tube is used here, which also has the effect of mixing the materials.
In this embodiment, when the dividing machine is applied, the driving device is started to enable the material to rotate at a constant speed, the material is poured into the material from the feeding hole of the material guiding pipe 2, the material slides out of the discharging hole in an accelerating way along the channel in the pipe under the action of gravity and is thrown to the conical material receiving surface from the discharging hole, and the material can be uniformly sprayed to the conical material receiving surface along the circumferential direction due to the constant speed rotation. And one part of the material sprayed on the conical receiving surface falls into the second receiving opening opened on the conical receiving surface, and the other part is blocked by the solid surface and slides downwards along the conical receiving surface, so that the material enters into the first receiving opening, and further the shrinkage is completed. In this division machine, adopted the passage 2 to carry out the cloth, at first passage 2 generally adopts straight tube or arc tube, and it is very simple to make, and through the restriction material of passage 2, can avoid the material to splash moreover, guarantees accurate division. Through the uniform rotation of the material guiding pipe 2, the spraying is realized, and the spraying is more uniform, so that the divider can effectively solve the problems of difficult manufacturing and uneven division of the divider.
Further, the upper end orifice of the material guiding pipe is a feeding hole, while in actual operation, the material guiding pipe 2 is rotated, so that the upper end orifice of the material guiding pipe 2 is preferably circular for convenient material pouring, and the axis of the upper end orifice coincides with the axis of the material guiding pipe 2, so that the upper end orifice of the material guiding pipe 2 is static in size and position during rotation of the material guiding pipe 2, and then the material guiding pipe 2 is conveniently guided. Furthermore, in order to facilitate the pouring, the orifice at the upper end of the material guiding pipe 2 can be outwards expanded.
Further, a scraping device 3 is also provided, and the scraping device 3 and the material guiding pipe 2 are relatively fixed, and can be directly and fixedly connected or adopt the same or synchronous driving device. The scraping device 3 is used for scraping a conical receiving surface, and specifically, when the material guiding pipe 2 rotates, the scraping device 3 moves together with the material guiding pipe 2, so that cleaning is completed. It should be noted that the scraping device 3 should have a scraping surface against the conical receiving surface. Wherein the particular shape of the sweeping surface should be dependent on the sweeping means 3, the particular sweeping means 3 may be a brush assembly or a squeegee assembly. Depending on the nature of the material, the scraping section 31 of the scraping device 3 is preferably a rubber section, wherein the scraping section 31 is the point of abutment against the conical receiving surface. The scraping and sweeping part 31 is provided with a saw tooth shape on one side propped against the conical material receiving surface, so that the overlarge propped force between the edge of the second material receiving opening and the scraping and sweeping device 3 can be avoided.
Further, the driving device is generally a motor, and of course, driving devices such as wind power, water power and the like can also be used. For convenience of arrangement, it is preferable that the driving means includes a motor and a sprocket chain transmission 6 linked with the motor, and one end sprocket of the sprocket chain transmission 6 is relatively fixed with the lower end of the guide tube 2 to apply torque to the lower end of the guide tube 2, thereby causing the guide tube 2 to rotate. At this time, for convenience in arrangement, the chain needs to pass through the second material receiving port, and the material needs to fall down at the second material receiving port, in order to ensure the accuracy of the material, and the cleanliness of the chain, a supporting piece for supporting the material guiding pipe 2 can be used as a supporting pipe 7, and a part, located at the first material receiving port, of the chain wheel and chain transmission device is penetrated in the supporting pipe 7, so that the chain is protected through the supporting pipe 7, and the material is prevented from being separated from the first material receiving port by the material strip.
As described above, one of the first receiving port and the second receiving port is a sample reserving port, and the other is a sample discarding port. For convenience in setting and adjustment, the second receiving port is preferably a sample retaining port. Further, in order to control the division accuracy conveniently, the second material receiving opening is preferably provided with an opening and closing size adjustable bin gate, and it should be noted that, in order to ensure the division accuracy, the size adjustment direction of the bin gate should be along the circumferential direction so as to ensure that the second material receiving opening is always kept in the maximum opening state in the bus direction. The opening and closing adjustment of the bin gate can be achieved through a motor, and it is required to be noted that materials falling on the bin gate can slide along the bin gate, and then can continue to slide along the conical material receiving surface into the second material receiving opening.
Further, considering that the material guiding pipe 2 is in a rotating state when throwing the material, a certain centrifugal force exists in the thrown material, so that the thrown material can move forward along the conical material receiving surface along the rotating direction, and the shrinkage accuracy can be greatly influenced if the thrown material slides into the second material receiving opening. In this respect, it is preferred here that, in the direction of rotation of the feed pipe 2, the side of the second receiving opening through which the feed pipe 2 passes first is provided with a baffle 5 for extending the feed pipe 2, i.e. inwardly, in order to prevent material falling onto the conical receiving surface or the bin gate from slipping circumferentially into the second receiving opening. In the case where the closing direction of the door is the same as the rotation direction of the feed pipe 2, the dam 5 is preferably provided on the door and on the side of the door through which the feed pipe 2 passes. If the closing direction of the bin gate is opposite to the rotation direction of the material guiding pipe 2, the material blocking plate 5 is preferably arranged on the opening edge of the second material receiving opening, which is firstly passed by the material guiding pipe 2. When the scraping device is provided, the dam 5 should not block the movement of the scraping device, i.e., the height of the dam 5 should be lower than the deformable distance of the scraping portion.
After long-term operation, a small corner is formed between the scraping plate and the conical receiving surface, when the material is accumulated at the corner easily under the action of centrifugal force, the accumulated material at the corner not only easily affects the progress, but also has the effect of stopping the material when the material overflows the baffle plate 5, and the phenomenon is particularly easy to occur when the reduced material has high humidity. Based on this, a purging device 4 may also be provided for purging the accumulation between the dam 5 and the conical receiving surface. In general, an air duct and a high-pressure gas generating device for introducing a high-pressure gas into the air duct are used as the purging means.
In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
