Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

The first embodiment is as follows:

referring to fig. 1, a schematic structural diagram of a centralized feeder 100 for feeding multiple injection molding machines according to an embodiment of the present invention is shown. A centralized feeding machine 100 for feeding materials by multiple injection molding machines comprises a mixing shell 10, at least one mixing bin 20, a receiving bin 30, a mounting plate 40 and a leakage-proof plate 50.

With reference to fig. 2 to 9, in particular, the mixing housing 10 is provided with an opening side 11 and a first mixing space 12 is arranged inside, the opening side 11 is communicated with the first mixing space 12, and the mixing housing 10 is provided with an opening at a position corresponding to the opening side 11, that is, the first mixing space 12 is communicated with the outside through the opening.

Further, a first mixing space 12 is arranged in the mixing bin 20, and the mixing bin 20 is slidably connected with the mixing shell 10 through a pulley assembly 60. Wherein, the mixing bin body 20 comprises a top portion and a bottom portion, and a first feeding opening 22 is opened on the top portion; and the bottom is provided with a first mixing outlet.

In a specific embodiment, a second mixing space 21 is provided in the mixing bin 20, and a stirrer and a detector are provided in the second mixing space 21. A plurality of materials are conveyed into the second mixing space 21 from the first feeding opening 22, after the plurality of materials are conveyed, the detector senses whether the weight of the plurality of materials in the second mixing space 21 reaches the requirement of a preset proportioning ratio or not until the weight of the plurality of materials meets the requirement of the preset proportioning ratio, the stirrer is enabled to fully stir the plurality of materials, and finally, the valve arranged at the position of the first mixing outlet is opened, so that the mixed materials are discharged to a corresponding injection molding machine for processing of an injection molding process.

Wherein, in order to improve the detection to the batching ratio of multiple material, can make every kind of material discharge to the second compounding space 21 after, the corresponding response is then done to the detector, and after the weight to this material detects the completion, confirms no mistake back, discharges another kind of material again, this moment the detector detects two total weights, and then reachs the weight of another kind of material, so repeatedly operate, detect until accomplishing the weight to each material of required processing to make actual batching ratio can be close or reach predetermined batching ratio, improve the accuracy, and then improved the performance of the injection molding that the moulding plastics obtained.

Of course, in order to improve the efficiency of discharging the mixed materials, the bottom may be made funnel-shaped to avoid a portion remaining in the second mixing space 21.

Further, the material receiving bin 30 is also disposed in the first material mixing space 12 and is located at the bottom of the material mixing bin 20. Connect the storehouse body 30 to be equipped with and connect material space 31, the same connects the storehouse body 30 of material to be equipped with and connects material opening 32 and pay-off opening, and is concrete, connect material opening 32 to locate and connect the storehouse body of material to be close to the one side of the compounding storehouse body 20, and connect material opening 32 with first compounding export sets up relatively, and connects the opening that material opening 32 is greater than the opening of first compounding export to the material after mixing can be followed first compounding export is carried to connecing in the material space 31 completely through connecing material opening 32.

In connection with practical applications, in order to increase the efficiency of use of a centralized feeder 100 for feeding multiple injection molding machines, it is common to have the mixing silo 20 fill the first mixing space 12 as much as possible, so as to be able to accommodate more material. Therefore, in order to reduce the difficulty in detaching the mixing bin body 20, the material receiving bin body 30 is prevented from being obstructed in the process of moving and taking out the mixing bin body 20 from the first mixing space 12. For example, the mixing bin body 20 is taken out by sliding along the direction toward the opening side 11, that is, a height difference in the vertical direction is formed between the mixing bin body 20 and the material receiving bin body 30, that is, a height difference is formed between the first mixing outlet and the material receiving opening 32, and then the material receiving bin body 30 does not interfere with the mixing bin body 20 in the process of moving out of the mixing bin body 20 in the horizontal direction.

Further, a mounting plate 40 is provided at the open side 11 of the mixing housing 10 to cover the first mixing space 12. Specifically, the mounting plate 40 is detachably connected with the mixing housing 10. For example, a plurality of connecting members are arranged in the mixing housing 10, each connecting member is located on the opening side 11, and end faces of the plurality of connecting members are parallel to each other, so that when the mounting plate 40 is covered on the mixing housing 10, on one hand, the plurality of connecting members can play a role in positioning, so as to avoid that the mounting plate 40 falls into the first mixing space 12 in the process of matching connection with the mixing housing 10, and the difficulty of matching connection is increased; on the other hand, the mounting plate 40 is connected with a plurality of the connecting pieces in a matching manner by screw threads, so that the centralized feeding machine 100 for feeding by a plurality of injection molding machines can prevent the material from splashing and impacting the mounting plate 40 to influence the mounting stability of the mounting plate in the material conveying process.

With reference to fig. 3 and 4, further, a plurality of knob members 41 are disposed on a side of the mounting plate 40 away from the plurality of connecting members, the knob members 41 are connected to the connecting members in a one-to-one correspondence, and the mounting plate 40 can be tightly connected to the plurality of connecting members by rotating the knob members 41, or the mounting plate 40 and the connecting members can be loosely connected to remove the mounting plate 40, so that the efficiency of assembling and disassembling the mounting plate 40 is improved.

Of course, the mounting plate 40 can be made of a transparent material, so that an operator can observe the actual conveying condition of the material in the first mixing space 12 through the mounting plate 40, for example, the splashing condition of the material, the residual material and the blocking condition of the material can be observed, and the adjustment can be performed in time.

Further, the side leakage-proof plate 51 is disposed on one side of the mounting plate 40 close to the material receiving bin 30, and extends into the material receiving bin 30 through the material receiving opening 32.

In combination with the above, since the mounting plate 40 is mounted on the opening side 11 of the mixing casing 10, a gap is formed between one side of the mixing bin body 20 and the material receiving bin body 30 close to the opening side 11 and the mounting plate 40, so that the materials are easy to splash and fall into the gap to cause long-term accumulation and are difficult to remove, which affects the normal operation of the centralized feeding machine 100 for feeding of multiple injection molding machines. Then, the leakage-proof plate 50 is overlapped on the material receiving opening 32 of the material receiving bin 30 to cover the gap, so that the material splashed to the gap can enter the material receiving space 31 under the blocking effect of the leakage-proof plate 50. Through setting up leak protection plate, can collect the guide to the granular material of spill, it is internal to connect the feed bin with it to prevent granular material spill and the batching ratio deviation that leads to.

Referring to fig. 5, the pulley assembly 60 preferably includes, for example, at least one pair of slide rails 61 and at least one pair of pulleys 62, and at least one pulley 62 is slidably connected to each slide rail 61. Specifically, the slide rails 61 are arranged on two opposite sides of the mixing shell 10 close to the mixing cabin 20, and each pair of slide rails 61 are arranged in parallel and extend towards the opening side 11; the pulleys 62 are arranged on two opposite sides of the mixing bin body 20 close to the corresponding slide rails 61. Specifically, still be equipped with on the slide rail 61 with the card strip that its orbit equidirectional extension, relatively, pulley 62 locate with the draw-in groove that the card strip cooperation is connected to make pulley 62's cross section be the H shape, and then spacing pulley 62 is the slip orbit on slide rail 61.

Preferably, the centralized feeder 100 includes, for example, at least one pair of bosses 72 and at least one pair of buffers 71. The bosses 72 are fixedly arranged on the mixing shell 10, and each boss 72 is movably connected with a corresponding slide rail 61; the buffering members 71 are interposed between the corresponding bosses 72 and the slide rails 61, and the buffering members 71 and the bosses 72 are arranged in one-to-one correspondence. Wherein the slide rails 61 can be moved closer to or farther away from the corresponding bosses 72. For example, the buffer member 71 is a spring member, for example, when filling the material into the mixing bin body 20, because the speed of the material in the process of being discharged into the mixing bin body 20 is large, large impact is caused to the mixing bin body 20, and under the effect of the spring member, the impact caused by the material can be slowed down to a certain extent, specifically, the mixing bin body 20 can drive the slide rails 61 connected with the sliding bin body to move repeatedly in the same vertical direction to offset the impact caused by the material, so as to offset the impact, thereby prolonging the service life of the slide rails 61 and the pulleys 62.

Referring to fig. 8-9, in one embodiment, the sliding rails 61 are connected with the pulleys 62 in a one-to-one fit manner. Specifically, the compounding storehouse body 20 is equipped with two at least mounting grooves 25 for example, and mounting groove 25 is used for installing pulley 62, and the two one-to-one cooperation is connected, wherein, two mounting grooves 25 are located the compounding storehouse body 20 respectively with open on the both sides that the side 11 is adjacent, to the in-process of the interior filler material of the compounding storehouse body 20, because the material is the graininess, in can make the relative pulley 62 of the compounding storehouse body 20 take place the slope, for example the material piles up when being close to the position of opening the side 11 in second compounding space 21, can make the compounding storehouse body 20 towards the direction slope of opening the side 11, then, make the terminal surface of mounting groove 25 and the corresponding terminal surface contact of slide rail 61, and then avoid the compounding storehouse body 20 to take place to empty, be unfavorable for collecting the material. However, when the mixing silo 20 is in an inclined state, since the first feeding opening 22 is also arranged in an inclined manner, it is difficult to fully utilize the second mixing space 21, i.e. the materials overflow from the lower side of the first feeding opening 22.

Then, what make further improvement to above-mentioned technical scheme can make the quantity of mounting groove 25 be three, and at this moment, it is corresponding, and the quantity of pulley 62 is also three for be equipped with a pulley 62 on one of them slide rail 61, and be equipped with two pulleys 62 on another slide rail 61, and then form stable fitting surface, can make the steady horizontal sliding connection of compounding storehouse body 20 on slide rail 61, improved the utilization ratio to first compounding space 12 this moment.

Further, in order to further enable the mixing bin body 20 to be stably and slidably connected to the corresponding slide rails 61 through the pulleys 62, two pulleys 62 are slidably connected to each slide rail 61, and thus, under the cooperation of the four pulleys 62 and the two slide rails 61, the mixing bin body 20 can be stably connected to the mixing housing 10.

Of course, when the material is conveyed to the first mixing space 12, the sliding of the pulley 62 relative to the sliding rail 61 is avoided, and the derailment occurs, so that the length of the sliding rail 61 is slightly smaller than the width of the mixing housing 10. Specifically, the gap between one end of the slide rail 61 and the mounting plate 40 is smaller than the diameter of the pulley 62, and likewise, the other end of the slide rail 61 communicates with the corresponding inner wall of the mixing housing 10.

With reference to fig. 2, preferably, a first side leakage gap 34 is formed between the material receiving bin body 30 and the mixing shell 10; the centralized feeder 100 includes, for example, at least one side leakage prevention plate 51. Specifically, the one end of the side leakage preventing plate 51 is fixedly connected with the inner wall of the mixing shell 10, and the other end opposite to the side leakage preventing plate extends into the material receiving bin 30 through the material receiving opening 32, so as to cover the first side leakage gap 34, prevent the material from splashing before the first mixing outlet discharges into the material receiving bin 30, enable part of the material to splash into the first side leakage gap 34, and cause the deviation of the material mixing ratio finally output to the corresponding injection molding machine and the preset material mixing ratio.

Preferably, the height of the joint of the side leakage preventing plate 51 and the mixing material housing 10 and the height of the side leakage preventing plate 51 extending into the material receiving opening 32 form a height difference. Specifically, the side leakage preventing plate 51 faces the direction close to the material receiving bin 30, and the height of the side leakage preventing plate 51 in the vertical direction is gradually reduced, that is, the height is gradually increased, so that part of the material falling onto the side leakage preventing plate 51 can slide into the material receiving bin 30 along the surface of the side leakage preventing plate 51 under the action of gravity.

Preferably, the number of the mixing cabin bodies 20 can be two, and the two mixing cabin bodies are arranged in an overlapped mode.
