DETAILED DESCRIPTION

[0020] The utility model provides a dust removal structure for transporting bagged products. In order to make the purpose, technical solution and effect of the utility model clearer and more specific, the utility model is further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the protection scope of the utility model.

[0021] See also Figure 1 The utility model provides a transport and dust removal structure for bagged products, comprising a frame 1, a transport line 2 rotatably arranged on the frame 1, a first driving member 3 for driving the transport line 2 to rotate, a cover body 4 fixedly arranged on the frame 1, an air inlet duct 41 and an air outlet duct 42 arranged on the cover body 4, a blower (not shown in the figure) connected to the air inlet duct 41, a negative pressure machine (not shown in the figure) connected to the air outlet duct 42, two closed doors 5 arranged inside the cover body 4, and a second driving member 6 for driving the two closed doors 5 to close or open; the blower is used for blowing gas into the interior of the cover body 4 through the air inlet duct 41, and the negative pressure machine is used for forming a negative pressure inside the air outlet duct 42; the two closed doors 5 are respectively located upstream and downstream inside the cover body 4, and are respectively used to connect or close the interior of the cover body 4 with the outside.

[0022] After the bagging is completed, the powder product is transported downstream via the transport line 2, and the second drive member 6 drives the two closed doors 5 to open, so that the powder product can smoothly enter the interior of the cover body 4; then the second drive member 6 drives the two closed doors 5 to close, so that the cover body 4 is in a sealed state; during the operation of the transport line 2, the blower is started synchronously to blow gas to the cover body 4, and the dust, powder, etc. deposited on the outer packaging of the product are suspended by wind force, and then the negative pressure formed by the negative pressure machine is used to make the suspended substances quickly pass through the air outlet duct 42 and be sucked away, thereby achieving dust removal on the outer surface of the bagged product; the transport line 2 continues to transport the bagged product downstream, and the negative pressure machine continues to operate until the dust inside the cover body 4 is sucked clean; then the closed door 5 is opened, and the bagged product is transported to the outside of the cover body 4.

[0023] It should be noted that the blower and the negative pressure machine are both existing products and can be purchased directly from the market, so they will not be described in detail here.

[0024] The above structure uses wind and suction to remove dust from the outer surface of the product through the blower and negative pressure machine; through the second driving member 6 and two closing doors 5, the product located inside the cover body 4 can remain closed during the dust removal process, preventing dust from flying to the outside of the cover body 4, thereby ensuring the dust removal effect.

[0025] See also Figure 1 In some embodiments, the cover body 4 is provided with an installation slot, in which a filter screen 7 is placed, and the filter screen 7 is located below the air outlet duct 42. The filter screen 7 is used to intercept large particles such as labels, paper scraps, etc., to avoid blocking the air outlet duct 42 or affecting the operation of the negative pressure machine. Specifically, the filter screen 7 can be inserted into the installation slot, so that the filter screen 7 can be detachable and easy to replace.

[0026] See also Figure 1 and Figure 2In some embodiments, the second driving member 6 includes a cylinder 61 fixed on the outer wall of the cover body 4, a rack 62 connected to the output end of the cylinder 61, two gears 63 meshing with the rack 62, and a rotating shaft 64 passing through the middle of the corresponding gear 63; the extension direction of the rack 62 is parallel to the length direction of the cover body 4, and the two rotating shafts 64 respectively pass through the two sides of the cover body 4; the two closing doors 5 each include a first door body 51 and a second door body 52, the first door body 51 and the second door body 52 are respectively fixed to the outer peripheral wall of the corresponding rotating shaft 64, and the angle formed between the first door body 51 and the second door body 52 is 180°. By using a cylinder 61 to drive the rack 62 to move forward and backward, the two gears 63 can be synchronously rotated forward or reversed, thereby realizing the synchronous forward or reverse rotation of the two rotating shafts 64 and the two closed doors 5 fixed to the rotating shafts 64. For example, when the closed door 5 rotates forward 90°, the closed door 5 is in an open state; when the closed door 5 reverses 90°, the closed door 5 is in a closed state. The angles of the first door body 51 and the second door body 52 are limited so that the first door body 51 and the second door body 52 are horizontal, which facilitates the synchronous control of closing or opening of the closed door 5.

[0027] See also Figure 1 In some embodiments, a slider 65 is fixedly connected to the outer wall of the cover body 4, and the upper surface of the rack 62 is provided with a slide rail 66, and the slider 65 is slidably provided on the slide rail 66. Since the rack 62 is relatively long, the cooperation of the slider 65 and the slide rail 66 can reduce the vibration amplitude of the rack 62, thereby ensuring the meshing of the rack 62 and the gear 63.

[0028] See also Figure 1 In some embodiments, a first infrared transmitter 8 and a first infrared receiver (blocked by the first infrared transmitter 8) are provided upstream of the rack 1, and the first infrared transmitter 8 and the first infrared receiver are respectively located on both sides of the transport line 2; the first infrared transmitter 8, the first infrared receiver, and the cylinder 61 are respectively electrically connected to the control mechanism. Specifically, when the infrared rays emitted by the first infrared transmitter 8 are blocked by the powder product, the first infrared receiver uses the transmission of the signal to enable the control mechanism to drive the cylinder 61 to operate, thereby driving the closed door 5 to open.

[0029] See also Figure 1In some embodiments, a second infrared transmitter 9 and a second infrared receiver (second infrared transmitter 9) are further provided between the two closed doors 5, and the second infrared transmitter 9 and the second infrared receiver are respectively located on both sides of the transport line 2; the second infrared transmitter 9, the second infrared receiver, and the cylinder 61 are respectively electrically connected to the control mechanism. When the infrared rays emitted by the second infrared transmitter 9 are blocked by the powder product, the second infrared receiver uses the transmission of the signal to control the operation of the drive cylinder 61 and close the pneumatic closed door 5. When the powder product after dust removal moves to the upstream of the closed door 5 located downstream, the next powder product to be dusted will move to the first infrared transmitter 8 and the first infrared receiver located upstream, so that the two closed doors 5 are opened, so that the next powder product to be dusted enters the cover body 4, and the powder product after dust removal leaves the cover body 4.

[0030] See also Figure 1 In some embodiments, the transport line 2 includes a first rotating roller 21 and a second rotating roller 22 that pass through both sides of the frame 1, and a transport belt 23 that is wound between the first rotating roller 21 and the second rotating roller 22; any end of the first rotating roller 21 or the second rotating roller 22 is transmission-connected to the first driving member 3. The transport belt 23 is operated by the rotation of the first rotating roller 21 and the second rotating roller 22, so that the products on the transport belt 23 are transported downstream.

[0031] See also Figure 1 In some embodiments, the first driving member 3 includes a driving motor 31 disposed on the frame 1, a driving wheel 32 drivingly connected to the output end of the driving motor 31, a driven wheel 33 fixedly connected to any end of the first rotating roller 21 or the second rotating roller 22, and a transmission belt 34 wound between the driving wheel 32 and the driven wheel 33. The rotation of the driving motor 31 drives the driving wheel 32, the transmission belt 34 and the driven wheel 33 to rotate, thereby realizing the operation of the conveyor belt 23.

[0032] See also Figure 1 In some embodiments, the bottom of the frame 1 is further provided with a plurality of horizontal beams 11 extending left and right, and the upper and lower side walls of the plurality of horizontal beams 11 are penetrated with adjusting screws 12, and the corresponding adjusting screws 12 are threadedly connected with adjusting nuts 13, and the adjusting nuts 13 are fixedly connected to the corresponding horizontal beams 11, and the upper part of the adjusting screws 12 is fixedly connected with an adjusting hand wheel 14, and the lower part of the adjusting screws 12 is fixedly connected with a foot cup 15. The plurality of horizontal beams 11 can be used to support the frame 1, and the adjusting hand wheel 14 can be rotated to drive the adjusting screws 12 to change their positions relative to the adjusting nuts 13, thereby changing the length of the adjusting screws 12, so that each position of the frame 1 is level with the ground.

[0033] In summary, the utility model uses the blower and negative pressure machine to achieve dust removal on the outer surface of the product by using wind force and suction force; by providing the second driving member 6 and two closing doors 5, the product located inside the cover body 4 can remain sealed during the dust removal process, preventing dust from flying to the outside of the cover body 4, thereby ensuring the dust removal effect.
