Wherein, the feeding mechanism 100 is used for realizing automatic feeding and automatically feeding powder into the die. The mold is placed in a cavity of the pig mechanism 200.

After the required powder is put into the mold, the ingot pressing mechanism 200 performs ingot pressing work to press the powder into an ingot-shaped finished product, and the second acting force device 23 is arranged in the ingot pressing mechanism 200 to eject the powder ingot out of the mold and push the powder ingot out of the material pulling module 134 on the feeding mechanism 100 to the grabbing mechanism 300.

And (3) ingot pressing: after the powder is added according to the capacity in the die, ingot pressing is carried out so that the powder in the die forms a powder ingot.

And the depth of the mold in the mold is automatically adjusted according to the parameters in the parameter setting step.

The feed mechanism 100 effects automatic addition of powder by reciprocating over the die as powder is added to the die.

The powder ingot is automatically ejected out of the die after being formed into a powder ingot.

To improve efficiency, the ejector module pushes the powder ingot out of the processing surface during the feeding process by the reciprocating motion of the feeding mechanism 100 above the die.

In this embodiment, the powder ingots are arranged in an array form while being pushed out.

a transmission step: and carrying out integral grabbing and conveying on the powder ingots in the array form to a vessel. During transport, the powder ingots in the form of an array are preheated in a high frequency machine preheater.

In this process, the robot arm is used to transfer the powder to realize an automated production section.

The process can realize a complete set of automatic processing mode of the melamine resin powder.

Referring to fig. 2 and 3, as a specific embodiment, the specific structure of the feeding mechanism 100 includes:

a bin 110 for storing powder;

and the material pushing device 130 is communicated with the bottom of the material box 110 and is used for automatically adding the powder in the material box 110 into the die.

A fixed platform 24 is arranged at the bottom of the pushing device 130 to serve as a carrier of the pushing device 130. Meanwhile, the ingot pressing mechanism 200 is also arranged on the fixed platform 24, an opening is arranged on the fixed platform 24, and the top of the mold in the ingot pressing mechanism 200 is connected with the opening on the fixed platform 24.

The bottom of the material pushing device 130 may be a structure without any baffle, that is, a structure directly connected to the fixed platform 24, or may be a structure of a box 131, and a material outlet 133 is provided at the bottom, so that the powder in the material box 110 can be added into the mold during the movement of the material pushing device 130 on the fixed platform 24.

As a specific embodiment, the fixed platform 24 is provided with a limiting module 241 for limiting a moving track of the pushing device 130, and a related structure of a sliding rail may be adopted, the fixed platform 24 is provided with a sliding rail, the pushing device 130 is provided with a connecting member 251, and the pushing device 130 slides on the sliding rail through the connecting member 251. In this embodiment, two slide rails are adopted.

As a specific example, the bin 110 may be made of a transparent material, so that during the whole processing process, the worker can observe the remaining amount of powder in the bin 110 in real time to add the powder in time.

As a specific example, the inside of the bin 110 may be provided with a monitoring element for monitoring the powder content in the box 131, and a display module or an alarm device or the like may be matched to the monitoring element to play a role of a prompt.

In this embodiment, the monitoring element may be an infrared device, since the box 131 is filled with powder, the powder may automatically move downward during use, and an appropriate position inside the box 131 is provided with an infrared emitter and an infrared receiver on a set of opposite surfaces, respectively, when the powder falls below the infrared emitter, the infrared receiver may receive a signal, and at this time, a prompt of the display module or a prompt of the alarm device may be triggered, thereby realizing an automatic operation of adding powder in the hopper 110.

As a specific embodiment, the pushing device 130 may be provided with a pushing portion 132 located outside the box 131 for providing power to move the pushing device 130 on the limiting module 241. The pushing unit 132 is provided with a control module therein to set the pushing distance and the pushing period of the pushing device 130.

As a specific embodiment, the material containing mold is installed in the mold installation portion 120, and in order to more quickly fill the mold with powder during the material pushing process of the material pushing device 130, if the material pushing device 130 adopts a box 131 structure, the cross section of the material outlet 133 at the bottom of the material pushing device completely covers the material inlet of the material containing mold, or in the direction perpendicular to the pushing direction of the pushing device, the cross section of the material outlet 133 can completely cover the maximum width of the material inlet of the material containing mold during the pushing process of the material outlet 133. Therefore, when the pushing device 130 pushes, the cross section of the die can be covered by the powder, and rapid high-quality feeding is realized.

As a specific example, after the ingot pressing mechanism 200 presses the powder ingot in the material holding mold, the second force applying device 23 in the ingot pressing mechanism 200 may push the powder ingot out to the fixing platform 24, and at this time, an independent third force applying member may be disposed on the fixing platform 24 to push the powder ingot away from the position of the mold. At this time, the feeding mechanism 100 feeds again to realize a linked feeding-ingot pressing-pushing process.

As a specific example, the third force applying member can make full use of the movement of the pushing device 130, and the third force applying member is disposed on the pushing device 130. The end of the third force applying member in contact with the powder ingot is marked as the kick-out block 134. The kick-off modules 134 are shaped to match the powder ingot to reduce the impact on the powder ingot.

The material pulling module 134 can work independently, and as long as the second acting force device 23 pushes out the powder ingot, the material pulling module 134 can push the powder ingot to the lower part of the grabbing mechanism 300.

Or, the material pushing device 130 may not be provided with a separate driving component, and is directly installed at the front end of the box 131 of the material pushing device 130, and by setting the motion trajectory of the pushing device, when the material pushing module 134 pushes the powder ingot to the lower side of the grabbing mechanism 300, the pushing device can feed the mold at the same time, so that the simultaneous work of powder adding and powder ingot pushing is realized, the work cycle can be greatly reduced, and the processing efficiency is improved.

As a specific example, a cleaning part may be provided on the feeding mechanism 100 to blow out the powder remaining on the fixed platform 24 by blowing air to improve the cleanliness of the whole processing table.

As a specific example, the powder ingot is shaped as a cylinder, and the material pushing module 134 is shaped as an arc, which is consistent with the powder ingot.

Referring to fig. 4 and 5, as a specific embodiment, the ingot pressing mechanism 200 structurally includes a material accommodating member 212 for accommodating melamine resin powder; the first acting force device 22 is used for pressing an ingot on one surface of the material containing part 212; and the second force device 23 is connected with the material containing part 212 and is used for ejecting the pressed product out of the material containing part 212. Wherein the material containing part 212 can be replaced and comprises the ingot pressing end of the first force device 22, so that the production of powder ingots with different scales can be realized.

When the powder storage device is used specifically, powder is stored in the material storage part 212, then the powder is pressed and molded by the first acting force device 22, and finally the pressed and molded block is ejected by the second acting force device 23. The process can realize the automatic ingot pressing and molding of the powder.

As a specific example, if there is a relatively fine requirement for the size of the powder lump, a weighing module may be disposed on the top of the second force application member 213, and during the process of continuously injecting the powder into the material accommodating member 212, the weighing module performs weighing to make the powder amount reach the requirement, so that the cake weight after each processing is the same. After feeding, the pushing device 130 moves from the fixed platform 24 to trowel the redundant powder, the weight of the weighing module is the weight of the final powder ingot at the moment, and records are formed, and as the powder ingots are arranged in an array, as long as the several groups of the powder ingots grabbed by the grabbing mechanism 300 can be recorded, rapid positioning can be realized.

If need remind in time, can be provided with the threshold value in weighing module, when the result of weighing not in reasonable scope, report to the police promptly, need artifical intervention in order to adjust.

In order to adapt to different material containing modules, for example, in the case of the same cross section, powder ingots of different heights need to be produced, and at this time, the second force application member 213 of the material containing member 212 needs to be adjusted in height.

As a specific example, the height of the cake product can be changed by adjusting the depth adjusting module 25, which can be manually or automatically.

By way of example, the adjustment member 252 is configured to:

an adjustment rod 2521 for defining a sliding trajectory of the connection 251;

an adjustment block 2522 on the adjustment rod 2521 for defining a movement range of the connection member 251;

a stop 2523 on the connection 251 for movement between the adjustment blocks 2522;

wherein the position of the adjustment block 2522 on the adjustment rod 2521 is movable.

The moving range of the stopper 2523 is changed by manually changing the position of the adjusting block 2522, namely, the moving range of the position of the connecting member 251 is changed, and after the cake-shaped product is pushed out, the connecting member 251 is descended to the position of the adjusting block 2522, so that the cake-shaped product can quickly reach the specified position.

Taking an automatic mode as an example, the structure of the adjusting block 2522 is added to the structure of the electronic ruler, so that the height of the electronic ruler can be remotely controlled according to actual needs, and the size can be controlled.

The mode of in time modifying can also be selected, namely, the real-time weighing is carried out in the process of continuously injecting the powder, each height of the electronic ruler can correspond to the weight of the powder in the material containing part 212 under the current height, and when the weighing module detects that the current weight exceeds the weight of the powder at the current height, an adjusting signal is sent to the electronic ruler for adjusting, so that an automatic correcting mode can be realized.

As a specific embodiment, the power sources of the first acting force device 22 and the second acting force device 23 adopt hydraulic cylinders, and a hydraulic frame is arranged to fix each component.

The hydraulic frame adopts the design of four columns and five layers, the fixed platform 24 is used for fixing the powder channel and building the automatic powder feeding mechanism 100, and is connected with the array transmission mechanism, the second force application part 213 has the main function of changing the volume in the cavity of the material containing channel by using the depth adjusting module 25 to carry out powder weighing and metering, an electronic ruler is installed to automatically adjust the volume according to the requirement of the weight of a powder ingot by a program, and the lifting is responsible for lifting and ejecting the pressed powder ingot upwards to eject the cavity of the material containing channel to be demolded. The upper hydraulic cylinder is connected with the first force application piece 211 through a first force application piece 211 installation sliding block, and mainly has the main function of applying pressure to powder in the material containing channel cavity and pressing the powder into powder ingots, wherein the pressure can be set; the material containing channel is filled with powder through an automatic powder feeding mechanism 100 arranged on the die fixing platform 24, and ingots are pressed circularly.

As a specific embodiment, the ingot pressing process is divided into several steps:

a feeding step: and automatically adding the powder to be processed into the die, and pushing the removed powder ingot away from the upper part of the die before adding the powder into the die.

If the adjustment rod 2521 is adjusted manually, the weight of the powder ingot processed this time is set before the feeding step. And manually or remotely adjusting the depth of the die according to the set weight of the powder ingot.

If an automatic adjustment mode is adopted, taking the above embodiment as an example, the electronic ruler is adopted and the weighing module is arranged, then the weighing module is used for weighing the powder in real time in the process of adding the powder into the die, and the electronic ruler automatically adjusts the depth of the die according to the weight in the process of adding the powder.

And (3) ingot pressing: and carrying out ingot pressing and molding on the powder in the mold to obtain a powder ingot.

And (3) an ejection step: the powder ingot is ejected from the mold, and the powder is ingot-pressed from above the mold by the ingot pressing mechanism 200. In the ejection process, the ejection mechanism and the ingot pressing mechanism 200 are kept relatively static, in the process of ejecting the powder ingot, the ingot pressing mechanism 200 applies acting force to the powder ingot so that the upper part and the lower part of the powder ingot have acting force, and after the powder ingot is moved out of the die, the ingot pressing mechanism 200 continues to move so as to be separated from the powder ingot.

Referring to fig. 6, after the powder ingot is pressed into an ingot shape by the ingot pressing mechanism 200, the powder ingot is pushed out from the fixed platform 24 to the conveying part 311 by the material pushing module 134, and then the powder ingot is grabbed and transported by the grabbing module 320.

As a specific example, the conveying part 311 conveys the powder ingots at a fixed period, so that at least one row of the powder ingots is distributed on the conveying part 311 and the powder ingots are uniformly distributed.

In order to be able to increase the distribution density of the powder ingots even further, not only a row of powder ingots is realized, but also the powder ingots are formed into an array. The powder ingot is subjected to position change by the fourth force application member 312, taking the array as n × m as an example, the specific process is as follows: when the powder ingot is just pushed onto the conveying portion 311, the position is recorded as [1,1], and if the fourth force application member 312 is not operated, the conveying portion 311 performs a conveying operation to the position [1,2] for a distance period, which is a distance between two adjacent conveying positions, and so on, thereby forming a row array of 1 × m.

If the fourth force applying member 312 is activated, when the powder ingot is located at the position [1,1], the fourth force applying member 312 may push the powder ingot to the position [2,1] along a direction perpendicular to the conveying direction of the conveying portion 311 on the surface where the conveying portion 311 is located, the next powder ingot is placed at the position [1,1], and then the conveying portion 311 conveys the powder ingot again, and so on, so as to realize a 2 × m matrix distribution.

By analogy, for the first n powder ingots, the fourth force application member 312 is sequentially pushed to the positions [ n,1], [ n,1], …, [1,1], so as to obtain a column matrix of n × 1, and the conveying portion 311 conveys again, so that by analogy, a matrix of n × m can be obtained.

Of course, the driving control of the fourth force application member 312 is matched with a control module, the pushing distance is set every time according to the size of the matrix actually required, the distance between the matrixes to be formed is not necessarily equal, as long as the pushing at every time can realize the distinguishing of the positions, and the distance can be ensured as long as the adjacent powder ingots cannot be crossed.

As a specific example, the fourth force application member 312 may be matched with a sliding rail, a plurality of track points are disposed on the sliding rail, and the distribution of the track points corresponds to the n-row array, so that the fourth force application member 312 can be directly controlled to push the predetermined track points, thereby improving the pushing precision of the fourth force application member 312.

As a specific example, the fourth force-applying member 312 can move at a fixed distance, and a sliding rail is provided at the bottom of the conveying portion 311, and the relative movement between the fourth force-applying member 312 and the conveying portion 311 is realized by moving the conveying portion 311 in a direction perpendicular to the pushing direction of the pushing mechanism.

In the present embodiment, the conveying direction of the conveying portion 311 coincides with the pushing direction of the pushing mechanism.

As a specific example, the gripping members 322 of the gripping module 320 are distributed in the same array at the maximum array on the conveying part 311, which is generally the array of powder ingots on each conveying part 311. If the array distribution is not as dense as required due to the processing requirements of different powder ingots, the operation distance and the operation period of the conveying part 311 and the fourth force application member 312 can be adjusted, in this case, due to the distribution mode of the gripping members 322 in the embodiment, all the powder ingots on the conveying part 311 can be gripped simultaneously, and only if the utilization rate is not hundreds, there will be idle gripping members 322.

As a specific example, the grabbing mechanism 300 is provided with a positioning member for accurately positioning the grabbing member 322 to the powder ingot, and may be generally disposed on the grabbing member 322 or disposed on the main plate 321.

As a specific example, the grabbing mechanism 300 is matched with a track control module 330, so as to directly control the position of the grabbing member 322, replace the function of the positioning member, or make the positioning member used as an alternative, and improve the grabbing precision of the whole device.

In this embodiment, adopt the triaxial sliding structure that relatively commonly uses in the industrial production, namely, x axle slide rail, y axle slide rail and z axle slide rail, adopt sliding cylinder or sliding block to be connected between the adjacent slide rail. The position of the grabbing mechanism 300 is accurately positioned through cooperation of the x-axis slide rail and the y-axis slide rail, and finally accurate grabbing action is realized through the z-axis slide rail.

As a specific example, the z-axis slide rail and the gripping mechanism 300 are interconnected to achieve the up-and-down gripping action of the gripping mechanism 300.

As a specific example, the gripping member 322 employs a vacuum chuck structure to achieve gripping of the powder ingot without any damage to the surface of the powder ingot.

After the powder ingot is processed and formed, the next procedure is to carry out hot pressing final forming. In this process, the gripping mechanism 300 is provided with a conveying device for transferring the gripping mechanism 300 to the upper side of the hot press mechanism and placing the powder ingot into the vessel for hot press molding.

As a specific embodiment, the conveying device is in the form of a mechanical arm, more than one connecting arm 520 is arranged, the connecting arm 520 is connected with the grabbing mechanism 300, no acting force is generated between the connecting arm 520 and the grabbing mechanism 300 during the grabbing action of the grabbing mechanism 300, including the accurate positioning process realized by the three-axis sliding rail, after the grabbing mechanism 300 grabs all the powder ingots with the array structure, the grabbing mechanism 300 moves up and down through the z-axis sliding rail, so that the top of the grabbing mechanism 300 is connected with the connecting arm 520, and then the grabbing mechanism 300 is separated from the z-axis sliding rail. A telescoping structure may be provided on the connecting arm 520 to enable the gripping mechanism 300 to perform a downward action when gripping the powder ingot over the vessel.
