Description

Technical Field

[0001] The utility model relates to the field of material processing equipment, in particular to a material distribution device suitable for F0 zone. Background Art

[0002] With the progress of industrial intelligence and under the guidance of the people-oriented concept, production operations in dangerous environments are gradually undertaken by industrial robots, which can not only complete dangerous and heavy work, but also allow people to withdraw from the front-line production workshops to reduce personal injuries. In the F0 area, that is, the place where explosives, detonators, firing powders, pyrotechnics are stored and black powder is manufactured, processed and stored, a slight spark may cause an explosion, and electrical equipment should not be installed.

[0003] The commonly used distribution device in the F0 area can distribute the raw materials or solid fuel on the cross section of another vessel as required. When the distribution device uses hydraulic power, there is a risk of leakage of hydraulic oil and contamination of the product; the use of screw conveyors in ordinary environments can accurately control the falling and distribution of materials, but due to the special properties of pyrotechnics, it is necessary to avoid strong squeezing or friction, so screw conveyors cannot be used for distribution.

[0004] In view of the above problems, the utility model proposes a material distribution device suitable for the F0 zone.

[0005] The technical solution adopted by the utility model is as follows:

[0006] The present application provides a material distribution device applicable to the F0 area, the material distribution device comprising a frame, a material distribution mechanism, a material receiving mechanism and a motion mechanism all arranged in the F0 area, and also comprising a power source arranged in the non-F0 area;

[0009] By arranging the power source in the non-F0 area, the material distributing mechanism, the material receiving mechanism and the motion mechanism are arranged in the F0 area, and the material distributing mechanism of the material distributing device can safely distribute the material on the material receiving mechanism below through the motion mechanism.

[0010] Further, the power source is an air pump, and the motion mechanism includes a first pneumatic telescopic member and a second pneumatic telescopic member respectively connected to the air pump;

[0011] The material distributing mechanism comprises a material leaking component and a material distributing component;

[0012] The leakage component is installed on the frame through the first pneumatic telescopic member, and the first pneumatic telescopic member is used to drive the leakage component to reciprocate in the vertical direction;

[0013] The material distribution assembly is arranged below the material leakage assembly and is mounted on the frame through the second pneumatic telescopic member, and the second pneumatic telescopic member is used to drive the material distribution assembly to reciprocate in the vertical direction.

[0014] The power source is an air pump, the moving mechanism is a pneumatic telescopic part, the leakage component reciprocates in the vertical direction to make the material leak to the cloth component, and the cloth component reciprocates in the vertical direction to realize the cloth in the cross section, that is, the present application realizes the cloth by driving the pneumatic telescopic part to move with an air pump, so that when the cloth device is clothing in the F0 area, there will be no phenomenon of hydraulic oil leakage and contamination of the product, and the cloth is also more uniform.

[0015] Furthermore, the leakage component is used for refining and filtering raw materials.

[0016] Further, the first pneumatic telescopic member and the second pneumatic telescopic member are respectively the first pneumatic tendon and the second pneumatic tendon;

[0017] The second pneumatic muscles include at least two, and the two second pneumatic muscles are respectively pneumatic tendon A and pneumatic tendon B;

[0018] The pneumatic tendon A and the pneumatic tendon B are respectively arranged on both sides of the material receiving mechanism, and the expansion and contraction directions of the pneumatic tendon A and the pneumatic tendon B are along the horizontal direction and the expansion and contraction directions coincide or are parallel;

[0019] When the pneumatic muscle A extends, the pneumatic muscle B contracts, and when the pneumatic muscle A contracts, the pneumatic muscle B extends.

[0020] Furthermore, one end of the first pneumatic muscle is fixed to the frame, and the other end is fixed to the material distribution mechanism; one end of the second pneumatic muscle is fixed to the frame, and the other end is fixed to the material receiving mechanism.

[0021] Furthermore, the first pneumatic muscles include at least two, and the two first pneumatic muscles are arranged at intervals along the circumference of the material distribution mechanism.

[0022] During actual use, an electromagnetic valve is provided between the pneumatic muscle and the air pump, and the air supply and deflation switching of the pneumatic muscle is realized through the electromagnetic valve.

[0023] Furthermore, the leakage assembly includes a barrel, a filter screen, a scraper and a pneumatic motor;

[0024] The filter screen is arranged in the barrel, the scraper is arranged above the filter screen and is connected to the output shaft of the pneumatic motor. When the material enters the barrel, the scraper is driven by the pneumatic motor to rotate and evenly distribute the material above the filter screen on the filter screen.

[0025] The pneumatic motor drives the scraper to rotate, and the pneumatic muscle drives the material receiving mechanism and the material spreading mechanism to move, so that the pneumatic muscle has no rotating parts when working, reducing the risk of accidental collision and fire caused by the pneumatic motor driving the scraper to rotate.

[0026] Furthermore, the barrel has an upper shell, the pneumatic motor is arranged on the upper shell, and the output shaft is located inside the barrel. The output shaft and the barrel are arranged coaxially. The upper shell is also provided with a feed port for feeding.

[0028] The fabric assembly is hoisted on the frame by an anti-static fabric sling. By adjusting the installation length of the fabric sling, the inclination angle of the fabric assembly can be changed to match the repose angle of the material, thereby achieving precise control of material falling. The structure is simple and solves the problem of fire and explosion caused by the screw squeezing the material when using a screw conveyor for fabric delivery.

[0029] Furthermore, the material placing device further comprises an air hammer, and the air hammer is connected to the power source;

[0030] The air hammer is installed on the outer wall of the barrel. When material adheres to the inner wall of the barrel, the air hammer is used to impact the barrel to make the material leak out of the barrel smoothly.

[0031] Furthermore, the scraper is made of anti-static polytetrafluoroethylene;

[0032] The scraper and the filter screen are spaced apart in the vertical direction.

[0033] The scraper material is made of anti-static polytetrafluoroethylene, and the scraper does not contact the filter when rotating, so no friction is generated and the squeezing of the material is avoided. When the scraper evenly distributes the material above the filter on the filter, the material leaks into the bottom of the barrel at the same time. Since the scraper itself is made of anti-static material, the risk of static electricity accumulation caused by friction igniting the material is avoided.

[0034] Furthermore, the material distributing device also includes a movable material receiving hopper. When the material receiving mechanism finishes receiving the material, the movable material receiving hopper is used to move between the material distributing component and the material receiving mechanism to receive the remaining material that may drop from the material distributing component.

[0035] Furthermore, the material receiving mechanism includes a stop assembly, a tray, a conveying assembly and a lifting assembly;

[0036] The tray is arranged on the conveying assembly, and the tray is used to receive the falling materials from the material distributing mechanism;

[0037] The conveying assembly is arranged on the frame, and the conveying assembly is used to transport the pallet laterally. The conveying assembly forms a material distributing working position directly below the material distributing mechanism;

[0038] The lifting assembly is installed below the conveying assembly. When the pallet is transferred to the material distributing working position, the stopping assembly is used to limit the transmission of the pallet on the conveying assembly. At the same time, the lifting assembly lifts the pallet so that the material distributing mechanism can distribute the material to the pallet.

[0039] Furthermore, the stopping assembly is arranged on the frame or the conveying assembly.

[0040] Furthermore, the conveying assembly is a conveyor belt composed of multiple rollers, and the conveying assembly is driven by an air pump. In actual use, the two ends of the tray are located on the upper rollers for conveyance. In actual use, the rollers are driven by another air motor.

[0041] Furthermore, the material distribution device further comprises a controller, and the material receiving mechanism further comprises a weighing sensor, and the weighing sensor is electrically connected to the controller;

[0042] The weighing sensor is installed on the lifting assembly, and the weighing sensor is used to weigh and measure the pallet; when the mass of the pallet reaches a set value, the controller is used to control the motion mechanism to stop moving, control the lifting assembly to descend, and control the stop assembly to cancel the restriction on the transmission of the pallet on the conveying assembly.

[0043] The weighing sensor is used to feedback the quality of the material being dropped, which is beneficial to the quantitative control of the material distribution mechanism and accurate material distribution.

[0044] Further, the lifting assembly includes an airbag, a first mounting plate, a second mounting plate, a mounting frame, a limit block and a lifting column;

[0045] The first mounting plate is fixed on the frame, the lifting column is slidably arranged on the first mounting plate, the upper end of the lifting column is fixed to the mounting frame, and the lower end of the lifting column is fixed to the second mounting plate;

[0046] The weighing sensor is mounted on the mounting frame and is located between the mounting frame and the tray;

[0047] The limiting blocks are respectively arranged between the first mounting plate and the mounting frame and between the first mounting plate and the second mounting plate;

[0048] The airbag is installed between the first mounting plate and the mounting frame, and the airbag is connected to the power source. When the airbag expands, the airbag abuts against the mounting frame and causes the mounting frame to drive the tray to move away from the first mounting plate.

[0049] When the airbag contracts, the mounting frame drives the tray to move toward the side close to the first mounting plate under the action of gravity.

[0050] Furthermore, the lifting assembly also includes a linear bearing and a support plate, the linear bearing is installed on the mounting frame, and the lifting column is slidably penetrated on the first mounting plate through the linear bearing.

[0051] The support plate is arranged above the weighing sensor for contacting the pallet.

[0052] Furthermore, the material distribution device also includes a voltage stabilizing element, which is arranged in the non-F0 area, and the voltage stabilizing element is arranged between the motion mechanism and the power source, and the voltage stabilizing element is used to provide a standard pressure air source to the motion mechanism in the F0 area.

[0053] The working principle of the material distribution device provided in the present application is as follows: the material leakage component is installed on the frame through four first pneumatic tendons. When the material enters the material leakage component, the four first pneumatic tendons drive the material leakage component to shake up and down, and at the same time the pneumatic motor drives the scraper to rotate slowly. Under the dual effects of vibration and scraper push, the material is broken into blocks through the filter screen and falls into the material distribution component below.

[0054] When the pallet reaches the material distribution working position via the conveying assembly, the stopping assembly intercepts the pallet, and the lifting assembly lifts the pallet at the same time. At this time, the pallet leaves the roller of the conveying assembly, and the mass is completely pressed on the weighing sensor above the lifting assembly.

[0055] When the lifting assembly lifts the pallet into place, the two second pneumatic muscles drive the fabric assembly to vibrate horizontally, and the material begins to fall evenly into the pallet. The weighing sensor weighs in real time. When the weight reaches the requirement, the first pneumatic muscle, the second pneumatic muscle and the pneumatic motor stop working, and the fabric assembly no longer drops material. Then the lifting assembly descends, and the pallet returns to the conveying assembly. The stop assembly cancels the restriction, and the pallet flows into the next process along the conveyor line.

[0056] The beneficial effects of the utility model are:

[0057] (1) The material distributing device provided in the present application arranges an air pump in a non-F0 area, supplies air through a voltage stabilizing element, and directly or indirectly drives the first pneumatic muscle, the second pneumatic muscle, the roller, the cylinder, the air bag and the scraper of the material distributing device through the air pump, so that the material distributing device can distribute materials safely.

[0058] (2) The material distribution device provided in the present application reduces the friction between the material and the device and the individual components of the device by providing an anti-static scraper and a vertical spacing distance between the scraper and the filter, thereby reducing the risk of collision and fire.

[0059] (3) The material distributing device provided in the present application realizes material discharging by using the first pneumatic muscle to realize the up and down vibration of the material leakage component, the second pneumatic muscle to realize the horizontal vibration of the material discharging component, the scraper to evenly flatten the concentrated materials, and the control and coordination of components such as the weighing sensor, so that the material distributing device can realize precise material distributing.

[0092] The filter screen 212 is arranged in the barrel 211 , and the scraper 213 is arranged above the filter screen 212 and connected to the output shaft of the pneumatic motor 214 . When the material enters the barrel 211 , the scraper 213 rotates under the drive of the pneumatic motor 214 and evenly distributes the material above the filter screen 212 on the filter screen 212 .

When the tray 320 is transferred to the material distributing working position, the stopping assembly 310 is used to limit the transmission of the tray 320 on the conveying assembly 330.

[0113] The weighing sensor 350 is used to feedback the quality of the blanking material, which is beneficial to the quantitative control and precise material distribution of the material distribution mechanism 20.

[0116] The weighing sensor 350 is mounted on the mounting frame 344 and is located between the mounting frame 344 and the tray 320;

[0117] The limit blocks 345 are respectively arranged between the first mounting plate 342 and the mounting frame 344 and between the first mounting plate 342 and the second mounting plate 343; when the airbag 341 is ventilated and expanded or deflated and contracted, the limit blocks 345 are respectively used to limit the rising or falling height of the lifting column 346.

[0118] The airbag 341 is installed between the first mounting plate 342 and the mounting frame 344. The airbag 341 is connected to the power source. When the airbag 341 expands, the airbag 341 abuts against the mounting frame 344 and the mounting frame 344 drives the tray 320 to move away from the first mounting plate 342.

[0119] When the airbag 341 contracts, the mounting frame 344 drives the tray 320 to move toward the first mounting plate 342 under the action of gravity.

[0120] In this embodiment, the lifting assembly 340 further includes a linear bearing 347 and a support plate 348 . The linear bearing 347 is mounted on the mounting frame 344 , and the lifting column 346 is slidably disposed on the first mounting plate 342 via the linear bearing 347 .

[0122] In this embodiment, the material distribution device further includes a voltage stabilizing element, which is disposed in the non-F0 area and between the motion mechanism 40 and the power source, and is used to provide a standard pressure gas source to the motion mechanism 40 in the F0 area.

[0123] The working principle of the material distribution device provided in the present application is as follows: the material leakage component 210 is installed on the frame 10 through four first pneumatic tendons. When the material enters the material leakage component 210, the four first pneumatic tendons drive the material leakage component 210 to shake up and down, and at the same time, the pneumatic motor 214 drives the scraper 213 to rotate slowly. Under the dual effects of vibration and the push of the scraper 213, the material is broken into blocks through the filter screen 212 and falls into the material distribution component 220 below.

[0124] When the pallet 320 reaches the material distribution working position via the conveying assembly 330 , the stopping assembly 310 intercepts the pallet 320 , and the lifting assembly 340 lifts the pallet 320 . At this time, the pallet 320 leaves the roller 331 of the conveying assembly 330 , and the mass is completely pressed on the weighing sensor 350 above the lifting assembly 340 .

[0125] When the lifting assembly 340 lifts the pallet 320 into place, the two second pneumatic muscles drive the cloth assembly 220 to vibrate horizontally, and the material begins to fall evenly into the pallet 320. The weighing sensor 350 weighs in real time. When the weight reaches the requirement, the first pneumatic muscle, the second pneumatic muscle and the pneumatic motor 214 stop working, and the cloth assembly 220 no longer drops material. Then the lifting assembly 340 descends, and the pallet 320 returns to the conveying assembly 330.
