Description

Technical Field

[0001] The invention relates to a packaging machinery system, in particular to a fully automatic valve bag supplying machine for an ultrafine powder packaging line. Background Art

[0002] As we all know, since the 1970s, the production of ultrafine powders has reached a certain scale, which can ensure efficient and high-quality automated production. However, due to the late start of the automated packaging of ultrafine powders, its degree of automation is far lower than that of production. Currently, there are two types of packaging bags for ultrafine powders: valve bags and open bags. Valve bags are difficult to automatically supply bags due to their small opening and thick thickness. Workers need to manually take out and put on bags. Working for a long time in such a harsh environment has a significant impact on the health of workers. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a fully automatic valve bag supply machine for an ultrafine powder packaging line that can realize the automatic bag supply function of ultrafine powder using valve bags, replace manual operation, and improve production efficiency.

[0004] The technical solution adopted by the present invention to solve the technical problem is: a fully automatic valve bag feeding machine for an ultrafine powder packaging line comprises a frame; a bag dividing device is arranged on the frame, and the bag dividing device comprises a feeding box; the feeding box has a vertical inner cavity; an opening is arranged on one side of the vertical inner cavity;

[0005] A bag transfer device is provided on one side of the feeding box with an opening; a bag loading device is provided between the bag transfer device and the feeding box;

[0006] The bag loading device comprises a base, a lifting plate is arranged above the base; a telescopic rod is arranged between the lifting plate and the base; a driving device of the telescopic rod is arranged on the base; and a conveying roller is arranged on the lifting plate;

[0007] A tray is slidably mounted in the vertical inner cavity of the loading box; an elastic telescopic device is arranged under the tray;

[0008] A separation device is provided at one end of the top of the feed box; the separation device comprises a separation roller; the minimum distance between the outer circumferential surface of the separation roller and the top surface of the feed box is less than or equal to the thickness of the valve bag;

[0009] A driving motor for driving the separation device is provided on one side of the loading box; the driving motor is drivingly connected to the separation roller;

[0010] A conveying chute is arranged at one end of the feeding box; the upper end of the conveying chute is flush with the feeding box and is located below the separation roller; a horizontal conveyor belt is arranged at the lower end of the conveying chute; a limiting pressure roller is arranged on the top of the feeding box; and the limiting pressure roller is installed on the feeding box through a telescopic device.

[0011] Furthermore, the separation roller has a central rotating shaft, the two ends of the separation roller are pressure sections, and the middle part is a friction section; a rubber layer is provided on the outer peripheral surface of the pressure section; the pressure section is a turntable installed on the rotating shaft; the friction section includes a rotating sheet evenly distributed along the circumference provided on the rotating shaft, one end of the rotating sheet is fixedly connected to the rotating shaft, and the other end is provided with a right angle.

[0012] Furthermore, the separation device also includes a pulley; the pulley is drivingly connected to the separation roller; and the pulley is drivingly connected to the drive motor via a belt.

[0013] Preferably, the telescopic rod is a pneumatic or hydraulic telescopic rod, and the driving device is a pneumatic cylinder or a hydraulic cylinder; or the telescopic rod is an electric telescopic rod, and the driving device is a motor.

[0014] Specifically, the conveying roller on the lifting plate is driven to rotate by a motor.

[0015] Specifically, the outer circumferential surface of the limiting pressure roller is a smooth surface.

[0016] Preferably, the elastic expansion and contraction device adopts a spring.

[0017] The beneficial effect of the present invention is that the fully automatic valve bag feeding machine for the ultrafine powder packaging line of the present invention utilizes the difference in friction coefficient. The surface of the valve bag is woven from plastic film, and the friction coefficient between them is small. The separation roller has a rubber with a large friction coefficient. When the equipment is running, due to the difference in friction, the uppermost valve bag moves forward under the drive of the separation roller to achieve separation.

[0018] Secondly, the restorability of the compression spring is used to realize the upward transfer of the valve bag, while providing upward pressure to press the valve bag and increase the friction difference.

[0019] Finally, the separation roller is composed of a pressure section and a friction section, wherein the pressure section maintains the overall stability of the valve bag and provides vertical constraints. The friction section is a discontinuous roller. This design is because there are seams at both ends of the valve bag, which are made of paper and have an uneven surface. The use of discontinuous rollers can increase the contact probability between the friction roller and the outer surface of the plastic and improve reliability. At the same time, since the friction roller is designed to be L-shaped and chamfered, if the friction roller cannot effectively contact the plastic film, the contact between the right-angle end and the seam is used to provide forward power.

[0020] Therefore, the fully automatic valve bag supply machine for the ultrafine powder packaging line described in the present invention can effectively improve the production environment of the enterprise, reduce labor intensity and labor cost, and meet the new requirements of the enterprise to improve the degree of automation and production efficiency.

[0029] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0030] like Figures 1 to 5 As shown, the fully automatic valve bag feeding machine for the ultrafine powder packaging line of the present invention comprises a frame 1; a bag dividing device is arranged on the frame 1, and the bag dividing device comprises a feeding box 2; the feeding box 2 has a vertical inner cavity; an opening 21 is arranged on one side of the vertical inner cavity;

[0031] A bag transfer device 10 is provided on one side of the loading box 2 where the opening 21 is provided; a bag loading device 11 is provided between the bag transfer device 10 and the loading box 2;

[0032] The bag loading device 11 comprises a base 111, a lifting plate 113 is arranged above the base 111; a telescopic rod 112 is arranged between the lifting plate 113 and the base 111; a driving device 115 of the telescopic rod 112 is arranged on the base 111; and a conveying roller 114 is arranged on the lifting plate 113;

[0033] A tray 6 is slidably mounted in the vertical inner cavity of the loading box 2; an elastic telescopic device 5 is provided below the tray 6;

[0034] A separation device 8 is provided at one end of the top of the feed box 2; the separation device 8 comprises a separation roller; the minimum distance between the outer circumference of the separation roller and the top surface of the feed box 2 is less than or equal to the thickness of the valve bag;

[0035] A driving motor 4 for driving a separation device 8 is provided on one side of the loading box 2; the driving motor 4 is drivingly connected to a separation roller;

[0036] A conveying chute 3 is provided at one end of the feeding box 2; the upper end of the conveying chute 3 is flush with the feeding box 2 and is located below the separation roller; a horizontal conveyor belt 12 is provided at the lower end of the conveying chute 3; a limiting pressure roller 9 is provided on the top of the feeding box 2; and the limiting pressure roller 9 is installed on the feeding box 2 through a telescopic device 91.

[0037] During the application process:

[0038] 1. The bundled valve bags 7 are placed on the bag transfer device 10, which uses a conveyor belt or a roller transmission device; the valve bags 7 are transported to the bag loading device 11 by the conveyor 10;

[0039] 2. After the valve bags 7 in the upper material box 2 are separated, it is necessary to add valve bags 7 to the upper material box 2. At this time, the driving device 115 is started to extend the telescopic rod 112 so that the lifting plate 113 is raised until the lifting plate 113 is flush with the tray 6;

[0040] At the same time, the telescopic device 91 is started to raise the limiting pressure roller 9, and the minimum distance between the limiting pressure roller 9 and the top surface of the loading box 2 is greater than or equal to the height of the valve bag 7 bundle.

[0041] 3. Then start the conveying roller 114 on the lifting plate 113 to convey the valve bag 7 to the tray 6; start the telescopic device 91 to lower the limit pressure roller 9 and press the tray 6 downward until the uppermost valve bag 7 is flush with the top surface of the loading box 2. The tray 6 is pressed toward the limit pressure roller 9 by the upward restoring force of the elastic telescopic device 5.

[0042] 4. The uppermost valve bag 7 contacts the separation roller, and the tray 6 and the valve bag 7 stop moving upward.

[0043] 5. The separation roller rotates. Since the friction between the separation roller and the valve pocket 7 is greater than the friction between the valve pockets, the uppermost valve pocket 7 moves forward with the rotation of the separation roller, while the lower valve pocket 7 remains stationary due to the obstruction of the base box, the friction of the friction pad on the base, and the small gap between the separation roller and the inclined plate.

[0044] 6. When the rear end of the uppermost valve bag 7 leaves the separation roller, it falls into the conveying chute 3. There is a positioning groove in the conveying chute 3 to send the valve bag to the next stage at a suitable angle.

[0045] 7. At the same time, due to the upward restoring force of the elastic telescopic device 5, the second layer of valve bag 7 begins to contact the separation roller.

[0046] In summary, the fully automatic valve bag feeding machine for the ultrafine powder packaging line of the present invention utilizes the difference in friction coefficient. The surface of the valve bag is woven from plastic film, and the friction coefficient between them is small. The separation roller has a rubber with a large friction coefficient. When the equipment is running, due to the difference in friction, the uppermost valve bag moves forward driven by the separation roller to achieve separation.

[0047] Secondly, the restorability of the compression spring is used to realize the upward transfer of the valve bag, while providing upward pressure to press the valve bag and increase the friction difference.

[0048] Therefore, the fully automatic valve bag supply machine for the ultrafine powder packaging line described in the present invention can effectively improve the production environment of the enterprise, reduce labor intensity and labor cost, and meet the new requirements of the enterprise to improve the degree of automation and production efficiency.

[0049] In order to increase the friction between the separation roller and the valve bag 7, the separation roller further has a central rotating shaft, the two ends of the separation roller are pressure sections 82, and the middle part is a friction section 83; a rubber layer is arranged on the outer peripheral surface of the pressure section 82; the pressure section is a turntable installed on the rotating shaft; the friction section 83 includes a rotating sheet evenly distributed along the circumference arranged on the rotating shaft, one end of the rotating sheet is fixedly connected to the rotating shaft, and the other end is arranged at a right angle.

[0050] The separation roller is composed of a pressure section and a friction section, wherein the pressure section maintains the overall stability of the valve bag and provides vertical constraints. The friction section is a discontinuous roller. This design is because there are seams at both ends of the valve bag, which are made of paper and have an uneven surface. The use of discontinuous rollers can increase the contact probability between the friction roller and the outer surface of the plastic and improve reliability. At the same time, since the friction roller is designed to be L-shaped and chamfered, if the friction roller cannot effectively contact the plastic film, the contact between the right-angle end and the seam is used to provide forward power.

[0051] In order to facilitate transmission and simplify the structure, the separation device further includes a pulley 81; the pulley 81 is transmission-connected to the separation roller; and the pulley 81 is transmission-connected to the drive motor 4 via a belt.

[0052] In order to facilitate control and simplify the structure, preferably, the telescopic rod 112 is a pneumatic or hydraulic telescopic rod, and the driving device 115 is a cylinder or a hydraulic cylinder;

[0053] Alternatively, the telescopic rod 112 is an electric telescopic rod, and the driving device 115 is a motor.

[0054] For ease of control, preferably, the conveying roller 114 on the lifting plate 113 is driven to rotate by a motor.

[0055] In order to reduce the friction between the valve pocket and the limiting pressure roller 9, preferably, the outer peripheral surface of the limiting pressure roller 9 is a smooth surface.

[0056] In order to simplify several parts and reduce the cost, preferably, the elastic telescopic device 5 adopts a spring.
