Detailed Description
In the description of the present invention, it is to be understood that the terms "front", "rear", "upper", "lower", "left", "right", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
The present invention will be described in further detail with reference to the following embodiments, and fig. 1 shows a schematic state diagram of a quantitative mixing device for particulate materials and a conveying line in the present invention, wherein it can be seen that the quantitative mixing device for particulate materials is attached to a particulate packaging line for mixing two different particulate materials according to a rated ratio. After being weighed and mixed by the granular material quantitative mixing equipment, the granular materials are filled into the woven bags, and then the filled woven bags are conveyed to the next working procedure (such as bag opening sewing, integral weighing, posture overturning adjustment and the like) by the conveying line.
Fig. 2 and 3 are schematic perspective views respectively showing two different states of the quantitative mixing device for granular materials in the present invention, and it can be understood that the quantitative mixing device for granular materials mainly comprises a frame 1, an initial feeding hopper 2, a weighing unit 3, a mixing hopper 4, and the like. Wherein, initial feeder hopper 2, weighing unit 3 and mixing hopper 4 are supported by frame 1, and arrange according to the preface along direction from top to bottom. As shown in fig. 5, the weighing unit 3 is constituted by a first weighing hopper 31 and a second weighing hopper 32 placed side by side. As shown in fig. 4, a partition 21 is provided in the initial feeding hopper 2 to partition a first feeding path 22 and a second feeding path 23, which are independent of each other, in an inner cavity thereof to face a first weighing hopper 31 and a second weighing hopper 32, respectively. As shown in fig. 6, 15 and 16, the first weighing hopper 31 comprises a bin body 311, a force transmission bracket 312, a load cell 313 and a first material release mechanism 314. The force transmission bracket 312 is always contacted with the bin body 311 so as to indirectly transmit the weight of the contained materials to the weighing sensor 313. The load cell 313 is always pressed between the force transmission bracket 312 and the frame 1. The first material releasing mechanism 314 is matched with the silo body 311 to control the open/close state of the outlet of the silo body 311.
It should be noted that the first weighing hopper 31 and the second weighing hopper 32 have similar design structures and completely identical working principles, and the difference is only the difference between the types of the weighing sensors 313 selected respectively, and for the sake of brevity, the description is omitted here.
In practical application, two different particulate materials are first poured into the initial feeding hopper 2, and enter the first weighing hopper 31 and the second weighing hopper 32 through the first feeding channel 22 and the second feeding channel 23 respectively, after being weighed and verified respectively (namely, two weighing sensors 313 belonging to the first weighing hopper 31 and the second weighing hopper 32 respectively reach a set weight requirement), the operation of continuously feeding the particulate materials into the initial feeding hopper 2 is stopped immediately, the two different particulate materials fall into the mixing hopper 4 under the action of gravity to be uniformly mixed, then, the first material releasing mechanism 314 is started to open a discharge port of the mixing hopper 4, and the mixed particulate materials are poured into a woven bag right below.
In the technical scheme disclosed by the invention, the two completely independent weighing sensors 313 are respectively used for measuring the weight of the granular materials contained in the first weighing hopper 31 and the second weighing hopper 32, so that the weighing precision and the sensitivity are higher. In addition, more importantly, when the ratio of the two premixed granular materials is changed, only two weighing sensors 313 belonging to the first weighing hopper 31 and the second weighing hopper 32 need to be subjected to parameter resetting, so that the application range of the granular material quantitative mixing equipment is effectively expanded, and the whole replacement operation process is very quick and efficient.
As is known, the force transmission bracket 312 can be designed in a variety of ways to meet its intended use, however, a simple design, easy to manufacture and low cost embodiment is proposed herein, as follows: as shown in fig. 9 and 10, the force transmission bracket 312 is mainly composed of a fixed seat 3121, a first vertical plate 3122, a second vertical plate 3123, and a force bearing plate 3124. Wherein, the fixing seat 3121 directly covers and is fixed on the corresponding weighing sensor 313. The first upright plate 3122 and the second upright plate 3123 are symmetrically fixed on two side walls of the fixing seat 3121. The bearing plate 3124 is always attached to the side wall of the bunker body 311, and is fixed to the first vertical plate 3122 and the second vertical plate 3123. During the process of filling the particulate material into the first weighing hopper 31, the pressure applied to the load cell 313 by the bin body 311 due to the self weight of the particulate material increases until the value of the load cell 313 reaches the design requirement, i.e., the operation of continuing to feed the particulate material to the first weighing hopper 31 is stopped.
It is known that the tightness of the combination of the force transmission bracket 312 and the first weighing hopper 31 has a crucial influence on the weighing accuracy, and if there is a gap between the two, the weighing accuracy is greatly reduced, and after multiple charging cycles, the bin body 311 is easily separated from the frame 1 due to unbalanced force, and therefore, as a further optimization of the structure of the first weighing hopper 31, a strip-shaped adjusting cushion plate 3125 is additionally provided. A strip trim pad 3125 lines the load bearing plate 3124 and the bin body 311 to ensure good contact between the load transfer bracket 312 and the first weigh bin 31.
Further, as shown in fig. 5-8, the first material release mechanism 314 preferably includes a first cylinder 3141, a cross beam 3142, and a striker plate 3143. The striker plate 3143 and the beam 3142 are detachably fixed as a whole, and perform drawing movement under the action of the driving force of the first cylinder 3141, so as to realize/release the plugging of the discharge port of the silo body 311. In the process of filling the granular material into the first weighing hopper 31, the material baffle 3143 is always kept in a pulled-out state to reliably block the discharge hole of the silo body 311. And when the numerical value belonging to the first weighing hopper 31 reaches the design requirement, the first air cylinder 3141 is started to drag the baffle plate 3143 to perform displacement movement backwards until the discharge hole of the bin body 311 is opened, so that the particle materials are guided to the mixing hopper 4 right below, and the subsequent mixing process is smoothly performed.
In addition, as shown in fig. 5 to 8, it can be seen that a guiding unit 3144 is further added to the first material releasing mechanism 314 to ensure that the striker 3143 always keeps good directivity in the process of being pulled, thereby effectively preventing the occurrence of the phenomenon of jamming due to "off tracking". The guide unit 3144 is composed of a first guide block 31441 and a second guide block 31442 detachably fixed to both sides of the magazine body 311. A first sliding groove and a second sliding groove (not shown in the figure) matched with the striker plate 3143 are respectively formed on the first guide block 31441 and the second guide block 31442. During the drawing process, the striker plate 3143 performs the directional sliding movement along the first sliding groove and the second sliding groove simultaneously.
As shown in fig. 11 and 12, the mixing hopper 4 includes a mixing hopper body 41 and a second material releasing mechanism 42. The second material releasing mechanism 42 is matched with the mixing hopper body 41 to control the opening/closing state of the discharge port of the mixing hopper body 41. Unlike the first material releasing mechanism 314, the second material releasing mechanism 42 is mainly composed of a first material stopping tongue 421, a second material stopping tongue 422, a first hinge shaft 423, a second hinge shaft 424, and a push-pull power unit 425. The first material blocking tongue 421 and the second material blocking tongue 422 are preferably sheet metal bent pieces (as shown in fig. 13 and 14), and are hinged to two sides of the mixing hopper body 41 by the first hinge shaft 423 and the second hinge shaft 424 in a one-to-one correspondence manner, and perform a swinging motion in an opposite direction/back-to-back direction under the action of the push-pull power unit 425. The push-pull power unit 425 includes a second cylinder 4251 and a third cylinder 4252. The second cylinder 4251 and the third cylinder 4252 are symmetrically arranged on two sides of the mixing hopper body 41 and are hinged between the first material stopping tongue piece 421 and the second material stopping tongue piece 422 at the same time. In the process of executing the material mixing operation, the first material blocking tongue piece 421 and the second material blocking tongue piece 422 are always kept in a closed state, and after two different granular materials are uniformly mixed, the second air cylinder 4251 and the third air cylinder 4252 are simultaneously started to drive the first material blocking tongue piece 421 and the second material blocking tongue piece 422 to execute reverse deflection movement until the discharge port of the material mixing hopper body 41 is completely opened, so that the mixed granular materials are favorably poured into the woven bag smoothly.
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.
