Description

Technical Field

[0001] This invention relates to the field of powder unpacking technology, and in particular to a powder unpacking device. Background Technology

[0002] In the rubber industry, the main function of auxiliary equipment is to transport and weigh various raw materials required for rubber mixing according to the formula requirements of the rubber mixing process and put them into the internal mixer in a certain proportion. Powder materials stored in bulk bags or small packages are generally unpacked manually. The powder enters the pressure tank from the powder unpacking equipment. High pressure and low speed compressed air is used to fluidize the powder in the tank and pressurize it before it is transported through pipelines.

[0003] Powder unpacking equipment serves as a transitional channel for materials entering the conveying unit. It can temporarily store a small amount of powder to be conveyed. In the rubber industry, powder unpacking equipment is usually a single unpacking station with low unpacking efficiency. Moreover, it cannot unpack and mix materials, increasing the risk of different rubber compounding quality due to different raw material quality. Furthermore, the valve plate inside the sealing valve of the powder unpacking equipment has a certain thickness. Due to the obstruction of the valve plate, the material passing through area is reduced, which not only affects the material discharge efficiency but also increases the risk of material blockage.

[0004] Therefore, how to provide a powder unpacking device that can effectively improve the efficiency of material feeding and reduce the risk of material blockage is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a powder unpacking device that can effectively improve the efficiency of material feeding and reduce the risk of material blockage.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A powder unpacking device includes a first unpacking chamber, a second unpacking chamber, a first unpacking frame, a second unpacking frame, a sealing mechanism, and a controller. The first unpacking frame is disposed on the top of the first unpacking chamber, and the second unpacking frame is disposed on the top of the second unpacking chamber. Both the first unpacking frame and the second unpacking frame are used to place a plastic bag containing materials. The sealing mechanism is electrically connected to the controller.

[0008] Both the first unpacking chamber and the second unpacking chamber include an unpacking port for feeding the material, and a feeding pipe for discharging the material is provided at the lower part of the unpacking port.

[0009] There are two sealing mechanisms, which are respectively placed in the first workstation unpacking chamber and the second workstation unpacking chamber. The sealing mechanism can rotate forward or backward by a preset angle to completely block or open the discharge port of the discharge pipe.

[0010] Preferably, the sealing mechanism includes a magnetic switch, a frame, a cylinder, a cylinder seat, a sealing door, and a rocker arm. The magnetic switch is mounted on the cylinder, and both the cylinder and the cylinder seat are mounted on the upper part of the frame. The feeding pipe and the sealing door are both mounted on the lower part of the frame.

[0011] The cylinder seat is disposed on the frame, the cylinder is mounted on the cylinder seat, one end of the rocker arm is placed on the upper part of the frame and connected to the telescopic rod of the cylinder, the other end of the rocker arm passes through the frame and is connected to the sealing door, and the rocker arm is rotatably connected to the frame;

[0012] The sealing gate includes a sealing plate, and a first side plate and a second side plate disposed on both sides of the sealing plate. The first side plate is connected to the rocker arm, and the second side plate is rotatably connected to the frame. The sealing plate can block the discharge port of the discharge pipe.

[0013] Preferably, the sealing mechanism further includes a protective cover, which is disposed on the frame, and the cylinder, the cylinder seat, and the rocker arm located on the upper part of the frame are all disposed inside the protective cover.

[0014] Preferably, it also includes a vibrating magnetic screen mechanism, wherein there are two vibrating magnetic screen mechanisms, which are respectively arranged at the lower part of the sealing mechanism in the first workstation unpacking chamber and the second workstation unpacking chamber;

[0015] The vibrating magnetic screen mechanism includes a turbine air vibrator, a magnetic screen assembly, and a foot valve, wherein the foot valve, the turbine air vibrator, and the magnetic screen assembly are connected in sequence.

[0016] Preferably, the magnetic screen assembly includes a screen body, round steel tubes and magnetic rods, wherein the screen body is provided with a plurality of round steel tubes, and each round steel tube contains a magnetic rod.

[0017] Preferably, the vibrating magnetic screen mechanism further includes a positioning component, which includes a stud, a spring, and a positioning sleeve. The stud is disposed between the support frame and the screen, and the top of the stud has a bent structure. The spring is sleeved on the outside of the stud, and the positioning sleeve is sleeved on the outside of the spring.

[0018] Preferably, it also includes inspection doors, wherein there are two inspection doors, which are respectively disposed on the first workstation unpacking chamber and the second workstation unpacking chamber at positions corresponding to the magnetic screen mechanism.

[0019] Preferably, it also includes a dust removal mechanism, which includes a dust collector, a first dust removal connector and a second dust removal connector. The first workstation unpacking chamber is connected to the dust collector through the first dust removal connector, and the second workstation unpacking chamber is connected to the dust collector through the second dust removal connector.

[0020] Preferably, it also includes a detection mechanism for detecting whether the space bag is in place. The detection mechanism includes a mounting base, a photoelectric switch, and a photoelectric switch cover. The photoelectric switch is disposed on the mounting base, and both the photoelectric switch and the mounting base are disposed inside the photoelectric switch cover.

[0021] Preferably, it also includes a blowing mechanism, wherein there are two blowing mechanisms, which are respectively arranged in the first workstation unpacking chamber and the second workstation unpacking chamber;

[0022] The blowing mechanism includes an electromagnetic pulse valve, a nozzle, and an air distribution pipe.

The air distribution pipe has multiple air outlets, and the workstation unpacking chamber has multiple nozzles. The air outlets are connected to the nozzles.

[0023] As can be seen from the above technical solution, the feeding point of the powder unpacking device has indicators for the target storage bin and the conveyed material. When the target storage bin issues a feeding request, the powder unpacking device receives the feeding signal and starts unpacking. The operator moves the material to the top of the first and second unpacking chambers using an electric hoist or overhead crane, waiting for unpacking. Then, the operator scans the material barcode on the space bag with a barcode scanner and transmits the material barcode information to the controller. If the material barcode information is inconsistent with the formula process production plan, the controller controls the sealing mechanism not to open, remaining in an initial sealing state. If the material barcode information is consistent with the formula process production plan, the controller controls the sealing mechanism to rotate forward by a preset angle, so that the discharge port of the discharge pipe is fully opened. At this time, the operator loosens the rope of the space bag, and the material can fall from the unpacking station into the discharge pipe for feeding. After feeding is completed, the controller can control the sealing mechanism to rotate backward by a preset angle to seal the discharge port of the discharge pipe.

[0024] Compared with the prior art, the powder unpacking device disclosed in the embodiments of the present invention can completely block or open the discharge port of the discharge pipe by the sealing mechanism, thus greatly increasing the discharge area of ​​the discharge pipe, effectively improving the material discharge efficiency and reducing the risk of material blockage.

[0025] Moreover, since the powder unpacking device disclosed in the embodiments of the present invention has two unpacking chambers, compared with the single unpacking chamber in the prior art, it not only effectively solves the problems of low unpacking efficiency and material mixing, but also reduces the risk of rubber quality differences caused by different quality of raw materials of the same variety but from different sources, and improves the uniformity and stability of the product.

Detailed Implementation

[0037] In view of this, the core of the present invention is to provide a powder unpacking device that can effectively improve the efficiency of material feeding and reduce the risk of material blockage.

[0038] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Please refer to... Figures 1 to 8 .

[0039] The powder unpacking device disclosed in this embodiment of the invention includes a first unpacking chamber 100, a second unpacking chamber 200, a first unpacking frame 101, a second unpacking frame 201, a sealing mechanism 500, and a controller. The first unpacking frame 101 is disposed on the top of the first unpacking chamber 100, and the second unpacking frame 201 is disposed on the top of the second unpacking chamber 200. Both the first unpacking frame 101 and the second unpacking frame 201 are used to place space bags containing materials. The sealing mechanism 500 is electrically connected to the controller.

[0040] Both the first unpacking chamber 100 and the second unpacking chamber 200 include unpacking port for material input, and a material unloading pipe 300 is provided at the lower part of the unpacking port for material unloading.

[0041] There are two sealing mechanisms 500, which are respectively placed in the first unpacking chamber 100 and the second unpacking chamber 200. The sealing mechanism 500 can rotate forward or backward by a preset angle to completely block or open the discharge port of the discharge pipe 300.

[0042] The powder unpacking device has indicators for the target storage bin and the conveyed material at the feeding point. When the target storage bin sends a feeding request, the powder unpacking device receives the feeding signal and starts unpacking. The operator moves the material to the first unpacking chamber 100 and the second unpacking chamber 200 using an electric hoist or overhead crane, waiting for unpacking. Then, the operator scans the material barcode on the space bag with a barcode scanner and transmits the material barcode information to the controller. If the material barcode information is inconsistent with the formula process production plan, the controller controls the sealing mechanism 500 not to open, remaining in an initial sealing state. If the material barcode information is consistent with the formula process production plan, the controller controls the sealing mechanism 500 to rotate forward by a preset angle, so that the discharge port of the discharge pipe 300 is fully opened. At this time, the operator loosens the rope of the space bag, and the material can fall from the unpacking station opening into the discharge pipe 300 for discharge. After the discharge is completed, the controller can control the sealing mechanism 500 to rotate backward by a preset angle to seal the discharge port of the discharge pipe 300.

[0043] Compared with the prior art, the powder unpacking device disclosed in the embodiments of the present invention can completely block or open the discharge port of the discharge pipe 300 by the sealing mechanism 500, thus greatly increasing the discharge area of ​​the discharge pipe 300, effectively improving the material discharge efficiency and reducing the risk of material blockage.

[0044] Moreover, since the powder unpacking device disclosed in the embodiments of the present invention has two unpacking chambers, compared with the single unpacking chamber in the prior art, it not only effectively solves the problems of low unpacking efficiency and material mixing, but also reduces the risk of rubber quality differences caused by different quality of raw materials of the same variety but from different sources, and improves the uniformity and stability of the product.

[0045] The embodiments of the present invention do not limit the specific structure of the sealing mechanism 500. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.

[0046] As a preferred embodiment, the sealing mechanism 500 disclosed in this embodiment of the invention includes a magnetic switch 501, a frame 502, a cylinder 503, a cylinder seat 504, a sealing door 505, and a rocker arm 506. The magnetic switch 501 is disposed on the cylinder 503. Both the cylinder 503 and the cylinder seat 504 are disposed on the upper part of the frame 502. The material feeding pipe 300 and the sealing door 505 are disposed on the lower part of the frame 502.

[0047] The cylinder seat 504 is mounted on the frame 502, the cylinder 503 is mounted on the cylinder seat 504, one end of the rocker arm 506 is placed on the upper part of the frame 502 and connected to the telescopic rod of the cylinder 503, and the other end of the rocker arm 506 passes through the frame 502 and is connected to the sealing door 505. The rocker arm 506 is rotatably connected to the frame 502.

[0048] The sealing gate 505 includes a sealing plate, and a first side plate 5051 and a second side plate 5052 disposed on both sides of the sealing plate. The first side plate 5051 is connected to the rocker arm 506, and the second side plate 5052 is rotatably connected to the frame 502. The sealing plate 5053 can block the discharge port of the discharge pipe 300.

[0049] It should be noted that the frame 502 is a flat plate structure with through holes. The rocker arm 506 passes through the through holes. The lower part of the frame 502 is provided with a first mounting plate and a second mounting plate, which are respectively located on both sides of the rocker arm 506. A first rotating pin passes through the first mounting plate and the second mounting plate and is rotatably connected to the rocker arm 506. A first side plate is connected to the bottom end of the rocker arm 506.

[0050] A third mounting plate and a fourth mounting plate are respectively provided on both sides of the second side plate, wherein the second rotating pin passes through the third mounting plate and the fourth mounting plate, so that the second side plate can rotate on the rotating pin.

[0051] With this configuration, both the first and second side plates can rotate, thereby causing the sealing plate 5053 to rotate in the forward or reverse direction.

[0052] To facilitate installation and disassembly, the powder unpacking device disclosed in this embodiment of the invention preferably has the feeding pipe 300 disposed on the lower end surface of the frame 502.

[0053] It should be noted that the magnetic switch 501 is electrically connected to the controller. When the magnetic switch 501 receives a signal that the material barcode is correct, it controls the cylinder 503 to open. The telescopic rod of the cylinder 503 extends and drives the sealing gate 505 to rotate forward by a preset angle through the rocker arm 506. When the magnetic switch 501 detects that the sealing gate 505 has fully opened the opening of the feeding pipe 300, it will issue a green warning light, indicating that feeding is allowed. At this time, the worker unties the rope of the space bag, allowing the material to fall into the feeding pipe 300 through the unpacking station. When the worker determines that there is no material in the space bag, the space bag is removed from the unpacking station; otherwise, a red warning light is issued, indicating that feeding is not allowed.

[0054] To prevent dust from adhering to the cylinder 503 and causing it to jam during operation, the sealing mechanism 500 disclosed in this embodiment of the invention further includes a protective cover 507. The protective cover 507 is mounted on the frame 502, and the cylinder 503, cylinder seat 504, and rocker arm 506 located on the upper part of the frame 502 are all disposed inside the protective cover 507. This arrangement prevents the cylinder 503 from jamming, ensuring smooth production.

[0055] It should be noted that a Y-type connector is preferably used to connect the rocker arm 506 and the telescopic rod of the cylinder 503.

[0056] As a preferred embodiment, the powder unpacking device disclosed in this embodiment of the invention further includes a vibrating magnetic screen mechanism 600, wherein there are two vibrating magnetic screen mechanisms 600, which are respectively disposed at the lower part of the sealing mechanism 500 in the first station unpacking chamber 100 and the second station unpacking chamber 200.

[0057] The vibrating magnetic screen mechanism 600 includes a turbine air vibrator 601, a magnetic screen assembly 602, and a foot valve 603, which are connected in sequence to the foot valve 603, the turbine air vibrator 601, and the magnetic screen assembly 602.

[0058] When feeding materials, stepping on the foot valve 603 causes the turbine air vibrator 601 to vibrate under the action of compressed air, which in turn drives the magnetic screen assembly 602 to vibrate up and down. This setting can effectively eliminate the accumulation of materials in the first station unpacking chamber 100 and the second station unpacking chamber 200, accelerate the falling of materials and improve the mixing degree of materials, so that different materials can be effectively mixed.

[0059] The specific structure of the magnetic screen assembly 602 is not limited in the embodiments of the present invention. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.

[0060] As a preferred embodiment, the magnetic screen assembly 602 disclosed in this embodiment of the invention includes a screen body 6021, a round steel tube 6022 and a magnetic rod 6023, wherein a plurality of round steel tubes 6022 are provided on the screen body 6021, and a magnetic rod 6023 is provided in any one of the round steel tubes 6022.

[0061] The support frame 605 is located at the lower part of the screen body 6021 to support the screen body 6021.

[0062] The specific arrangement of the round steel pipe 6022 in this embodiment of the invention is not limited. Any structure that meets the requirements of this invention is within the protection scope of this invention.

[0063] As a preferred embodiment, the round steel pipes 6022 disclosed in this embodiment of the invention are evenly distributed on the screen body 6021 at equal intervals. This arrangement can effectively prevent large foreign objects from falling into the first unpacking chamber 100 and the second unpacking chamber 200, and at the same time, it can also effectively adsorb small metal shavings and impurities in the material.

[0064] In order to enable the screen body 6021 to be flexibly connected to the support frame 605, the vibrating magnetic screen mechanism 600 disclosed in the embodiment of the present invention further includes a positioning component 604, wherein the positioning component 604 includes a stud 6041, a spring 6042 and a positioning sleeve 6043. The stud 6041 is disposed between the support frame 605 and the screen, and the top of the stud 6041 is a bent structure. The spring 6042 is sleeved on the outside of the stud 6041, and the positioning sleeve 6043 is sleeved on the outside of the spring 6042.

[0065] It should be noted that the positioning sleeve 6043 is preferably made of nylon, which guides the spring 6042. The screen body 6021 can be flexibly connected to the support frame 605 through the spring 6042, which plays a role in buffering and energy storage.

[0066] The bent structure at the top of the stud 6041 can effectively prevent the screen body 6021 from falling off when the vibrating magnetic screen mechanism 600 vibrates.

[0067] To facilitate maintenance of the vibrating magnetic screen mechanism 600, the powder unpacking device disclosed in this embodiment of the invention further includes maintenance doors 400 respectively disposed on the first station unpacking chamber 100 and the second station unpacking chamber 200, corresponding to the vibrating magnetic screen mechanism 600. When the vibrating magnetic screen mechanism 600 malfunctions, it can be maintained by opening and closing the maintenance doors 400.

[0068] In order to recover the dust raised during feeding and avoid environmental pollution, the powder unpacking device disclosed in this embodiment of the invention also includes a dust removal mechanism 700, wherein the dust removal mechanism 700 includes a dust collector 703, a first dust removal pipe 701 and a second dust removal pipe 702. The first station unpacking chamber 100 is connected to the dust collector 703 through the first dust removal pipe 701, and the second station unpacking chamber 200 is connected to the dust collector 703 through the second dust removal pipe 702.

[0069] When the unpacking is started, the dust removal mechanism 700 is connected and the dust removal fan is started. The dust raised during unpacking is connected to the dust collector 703 through the first dust removal pipe 701 and the second dust removal pipe 702 to absorb the dust flying during feeding.

[0070] As a preferred embodiment, the powder unpacking device disclosed in this invention further includes a detection mechanism 800 for detecting whether the space bag is in place. The detection mechanism 800 includes a mounting base 801, a photoelectric switch 802, and a photoelectric switch cover 803. The photoelectric switch 802 is disposed on the mounting base 801, and both the photoelectric switch 802 and the mounting base 801 are disposed inside the photoelectric switch cover 803.

[0071] When the photoelectric switch 802 detects that the space bag has been removed, it transmits the information to the controller. The controller controls the cylinder 503 to move, thereby driving the sealing door 505 to rotate in the opposite direction by a preset angle to completely block the discharge port. When the magnetic switch 501 detects that the sealing door 505 is completely closed, it waits for the next bag of material to be fed in.

[0072] The embodiments of the present invention do not limit the specific control method of cylinder 503. Any structure that meets the requirements of the present invention is within the protection scope of the present invention.

[0073] Preferably, the cylinder 503 disclosed in this embodiment of the invention uses a solenoid valve to control the opening and closing of the air path, thereby causing the cylinder to move. Since the control method of controlling the cylinder movement by a solenoid valve is prior art, this embodiment of the invention will not elaborate on it further.

[0074] It should be noted that there are two detection mechanisms 800, which are respectively set at the first dust removal pipe 701 and the second dust removal pipe 702. The photoelectric switch 802 detects whether the space bag is in place and transmits the detection result to the controller. The controller starts to execute the next process based on the detection.

[0075] It should be further explained that the photoelectric switch cover 803 not only prevents dust from adhering to the photoelectric switch 802 and affecting its stability, but also prevents the photoelectric switch 802 from being damaged by the space bag during hoisting.

[0076] As a preferred embodiment, the powder unpacking device disclosed in this embodiment of the invention also has multiple openings on the photoelectric switch cover 803 to adjust the sensitivity of the photoelectric switch 802.

[0077] To prevent materials from clumping and arching during the unpacking process, the powder unpacking device disclosed in this embodiment of the invention further includes a blowing mechanism 900. There are two blowing mechanisms 900, which are respectively arranged in the first station unpacking chamber 100 and the second station unpacking chamber 200.

[0078] The blowing mechanism 900 includes an electromagnetic pulse valve 901, a nozzle 902, and an air distribution pipe 903. One end of the electromagnetic pulse valve 901 is connected to compressed air, and the other end of the electromagnetic pulse valve 901 is connected to the air distribution pipe 903. The air distribution pipe 903 has multiple air outlets, and the workstation unpacking chamber has multiple nozzles 902. The air outlets are connected to the nozzles 902.

[0079] The blowing mechanism 900 uses an electromagnetic pulse valve 901 to blow compressed air through the air distribution pipe 90 and the nozzle 902 into the interior of the first station unpacking chamber 100 and the second station unpacking chamber 200, preventing the material from caking and arching in the conical wall of the dual station unpacking chamber.

[0080] Among them, the lower flange of the cone of the first station unpacking chamber 100 and the second station unpacking chamber 200 is usually connected to a double pressure conveying tank.

[0081] It should be noted that the blowing pressure should not exceed 0.25 MPa, otherwise it may cause personal injury and a large amount of powdery material to be scattered. The cleaning time is set in the control system of the powder unpacking device. After the control system determines the time, cleaning ends and the device awaits the next feeding instruction.
