Description

Technical Field

[0001] The utility model relates to the technical field of processing adsorption, in particular to an air suction disc device with auxiliary blanking. Background Art

[0002] In the processing industry, suction discs are usually used for auxiliary operations. However, existing suction discs have a low degree of automation, are noisy, require a lot of manpower, and pose a large safety risk. In particular, they are prone to damage to the materials during the blanking stage. Some manufacturers now have blanking components installed at the bottom of the suction disc to achieve the automatic falling of the materials. However, this blanking component is usually a structure in which the blanking plate is directly driven to rise and fall by multiple motors. There is a problem of unstable blanking, and the blanking plate will deform after long-term use, affecting the adsorption effect. Therefore, the existing suction discs still cannot meet market demand and need to be improved. Utility Model Content

[0003] Based on this, the purpose of the present invention is to provide a suction disc device with auxiliary blanking, which has the advantages of stable blanking and long service life.

[0004] A suction disc device with auxiliary blanking, comprising:

[0005] Support frame;

[0006] A suction fan is arranged on the support frame;

[0007] a bellows assembly, arranged on the support frame, comprising a box body and a wind shield arranged on the box body, the box body being provided with an air duct connected to the suction fan, and the wind shield being provided with an air cavity connected to the air duct;

[0008] A drive assembly includes a transmission shaft, a mounting seat, an eccentric wheel, a connecting member, a driving wheel and a blanking driving source. The transmission shaft is rotatably inserted into the wind hood, and both ends of the transmission shaft are rotatably installed on the mounting seat. There are two mounting seats and they are symmetrically arranged on both sides of the wind hood. The eccentric wheels are eccentrically installed near both ends of the transmission shaft. The eccentric wheels are rotatably connected to the connecting member through a bearing. The connecting member is movably inserted into the mounting seat. The driving wheel is also provided at one end of the transmission shaft, and the driving wheel is driven to rotate by the blanking driving source.

[0009] A blanking plate is located at the bottom of the wind cover and covers the outlet of the wind cavity. The blanking plate is provided with a plurality of ventilation holes and is connected to the end of the connecting piece.

[0010] The utility model discloses an air suction disc device with auxiliary blanking, which replaces the traditional multi-drive source structure with an eccentric drive structure, so that the blanking plate has higher synchronization when being raised and lowered, runs more smoothly, and is not easily deformed, thereby extending its service life.

[0011] Furthermore, the drive assembly has two groups and is installed in a centrally symmetrical layout, and the drive assembly drives the same blanking plate to rise and fall, which makes the device structure more compact and improves the fit between the blanking plate and the wind cover, ensuring the adsorption strength.

[0012] Furthermore, the connecting member includes a sleeve, a U-shaped connecting block, and a floating joint. The sleeve is mounted outside the bearing. One end of the U-shaped connecting block is hinged to the sleeve, with its hinge axis parallel to the transmission shaft. The other end of the U-shaped connecting block is connected to the blanking plate via the floating joint. This has a simple structure and is easy to maintain.

[0013] Furthermore, a mounting plate is provided on the blanking plate and connected to the floating joint via the mounting plate. This structure facilitates disassembly and maintenance while improving the stability of the blanking plate.

[0014] Furthermore, one end of the transmission shaft is sleeved with a driving wheel, and the blanking drive source is a servo motor, which drives the driving wheel to rotate through a synchronous belt. This structure can improve control accuracy.

[0015] Furthermore, a guide rod is provided through the mounting seat, and the bottom of the guide rod is connected to the blanking plate. This structure guides the movement of the blanking plate and improves the operation stability.

[0016] Furthermore, a buffer member is included, which is sleeved on the outside of the guide rod and compressed and clamped between the head of the guide rod and the mounting seat. This structure can achieve buffering while making it easier to reset the blanking plate.

[0017] Furthermore, air vents connected to the air duct are formed on both sides of the box body. The bellows assembly also includes blades, a rotating shaft, and a rotary drive source. The blades are rotated by the rotating shaft and arranged at the air vents. The rotary drive source drives the rotating shaft to rotate, thereby driving the blades to open or close the air vents. This structure can adjust the size of the air vents, while reducing the noise generated by the original flapping method and preventing damage caused by the flapping of the blades.

[0018] Furthermore, the shaft is provided with a positioning plate, which is provided with at least one positioning boss protruding radially outward. The housing is provided with a positioning sensor corresponding to the positioning plate, which is used to monitor whether the positioning boss is in place. This structure enables the fan blade rotation angle to be adjusted, improving control accuracy.

[0019] Furthermore, it also includes a motor protection cover, which is arranged on the box body and houses the rotary drive source, positioning plate and positioning sensor. This structure can provide protection and dustproof, improve safety and stability of device operation.

[0032] The utility model discloses an air suction disc device, comprising a support frame 1, a suction fan 2, a bellows assembly 3, a drive assembly 4 and a blanking assembly 5. The suction fan 2 and the bellows assembly 3 are respectively arranged on the upper and lower sides of the support frame 1, and the suction fan 2 can form a negative pressure in the bellows assembly 3. The bottom cover of the bellows assembly 3 is provided with a blanking assembly 5, and the blanking assembly 5 is driven to move up and down by the drive assembly 4 arranged on the bellows assembly 3. When the blanking assembly 5 is in contact with the bellows assembly 3, the material is adsorbed on the bottom of the blanking assembly 5 under the action of negative pressure; when the blanking assembly 5 descends and separates from the bellows assembly 3, the material is separated from the blanking assembly 5, thereby realizing blanking.

[0033] The bellows assembly 3 includes a box body 31, a wind cover 32, wind blades 33, a rotating shaft 34, a rotary drive source 35, an air outlet protective cover 36, a positioning plate 37 and a positioning sensor 38. The box body 31 is a square structure, and a through air duct is provided in the vertical direction. Air outlets connected to the air duct are also provided on both sides of the box body 31. Wind blades 33 are provided at the air outlet through the rotating shaft 34. The wind blades 33 shield the air outlet. The rotary drive source 35 drives the rotating shaft 34 to rotate, thereby driving the wind blades 33 to rotate, and then realizing the opening and closing of the air outlet. The rotary drive source 35 can be a rotary servo motor, which can control the opening angle of the wind blades 33, thereby controlling the air volume. The outer cover of the air outlet is provided with an air outlet protective cover 36, which can isolate debris while protecting the wind blades 33 and maintenance personnel.

[0034] The fan blades can rotate to 45 degrees, 90 degrees, 180 degrees, and 360 degrees depending on the desired operation and air outlet size, and can also rotate forward or backward as needed. To control the rotation of the fan blades 33, the rotating shaft 34 is also provided with a positioning disk 37. The positioning disk 37 is provided with at least one radially outwardly protruding positioning boss 371. Multiple positioning bosses 371 can be provided depending on the desired rotation angle. The drawings of this embodiment only show one positioning boss 371 as an example. The housing 31 is also provided with a positioning sensor 38. When the rotating shaft 34 rotates, the positioning boss 371 rotates. When the positioning boss 371 rotates to a position corresponding to the positioning sensor 38, the positioning sensor 38 sends a rotation position signal, thereby automatically controlling the opening or closing of the fan blades 33.

[0035] The motor protection cover 39 is provided on the box body 31 , and covers the rotation drive source 35 , the positioning plate 37 and the positioning sensor 38 inside.

[0036] The wind shield 32 is disposed at the bottom of the bellows assembly 3, and its inner cavity is connected to the bellows assembly 3. The wind shield 32 is provided with a drive assembly 4. The wind shield 32 has a trapezoidal structure that narrows from bottom to top, and the bottom of the wind shield 32 corresponds to the blanking assembly 5. The wind shield 32 has an air cavity that is connected to the air duct, and one or two sets of drive assemblies 4 are disposed on the outside. This embodiment is described using two sets of drive assemblies 4 as an example. The two sets of drive assemblies 4 are arranged in a centrally symmetrical layout and drive the same blanking assembly 5 to achieve lifting and lowering.

[0037] The drive assembly 4 includes a transmission shaft 41, a mounting seat 42, an eccentric wheel 43, a connector 44, a drive wheel 45, a blanking drive source 46, a guide rod 47, and a buffer 48. The wind hood 32 is provided with a transmission shaft 41, with both ends of the transmission shaft 41 rotatably mounted on the mounting seat 42. The mounting seat 42 has two symmetrical mounting seats 42 arranged on either side of the wind hood 32. Eccentric wheels 43 are eccentrically mounted near both ends of the transmission shaft 41. The eccentric wheels 43 are connected to the connector 44 via bearings. The connector 44 is movably mounted in the mounting seat 42, and its bottom end is connected to the blanking assembly 5. Sufficient clearance is required between the mounting seat 42 and the connector 44 to prevent interference between the connector 44 and the mounting seat 42 when the connector 44 swings. One end of the transmission shaft 41 is also provided with a drive wheel 45, which is connected to the blanking drive source 46 via a belt. The blanking drive source 46 is a servo motor and is mounted on the wind hood 32.

[0038] The connecting member 44 can have various structural forms. In this embodiment, the connecting member 44 includes a sleeve 441, a U-shaped connecting block 442 and a floating joint 443. The sleeve 441 is sleeved outside the bearing. One end of the U-shaped connecting block 442 is hinged to the sleeve 441, and its hinge axis is parallel to the transmission shaft 41. The other end of the U-shaped connecting block 442 is connected to the blanking plate 51 through the floating joint 443.

[0039] During use, the blanking drive source 46 is started, thereby driving the transmission shaft 41 to rotate through the driving wheel 45. At this time, the eccentric wheel 43 rotates in the sleeve 441, thereby driving the connecting part 44 to move up and down, and then driving the blanking assembly 5 to rise and fall. When the blanking assembly 5 rises, it fits with the wind cover 32, and the negative pressure formed inside the device can adsorb the material. When the blanking assembly 5 falls, the blanking assembly 5 is separated from the wind cover 32, and the outside air enters, making it impossible for the negative pressure to adsorb the material, thereby realizing the blanking of the material.

[0040] The mounting seat 42 is further provided with a guide rod 47, the bottom of which is connected to the blanking assembly 5. A buffer member 48 is sleeved on the outside of the guide rod 47 and is compressed and clamped between the head of the guide rod 47 and the mounting seat 42. The buffer member 48 can be a spring or the like.

[0041] The blanking assembly 5 includes a blanking plate 51 and a mounting plate 52. The blanking plate 51 can be a single-piece structure or composed of multiple plates. The blanking plate 51 is provided with a plurality of ventilation holes 511 and reinforcement ribs 512. The mounting plates 52 are disposed on both sides of the blanking plate 51 and are connected to the connector 44.

[0042] The utility model discloses an air suction disc device with auxiliary blanking, which replaces the traditional multi-drive source structure with an eccentric drive structure, so that the blanking plate has higher synchronization when being raised and lowered, runs more smoothly, and is not easily deformed, thereby extending its service life.
