Detailed Description of the Invention

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] In view of the deficiencies that the feeding position height dimension of some filter rod compounding machines is high, and the weight of the new filter rod is much greater than that of the conventional filter rod, and manual feeding has problems such as slow speed, inconvenient unloading, long duration, and large physical consumption, this embodiment provides an automatic filter rod unloading and feeding device. This automatic filter rod unloading and feeding device can, within a limited space, meet the requirements of stable feeding, appropriate lifting height, and rapid flipping and feeding, achieving the purpose of ensuring safe production and saving manpower and material resources to the greatest extent.

[0031] As Figure 1 shown, this automatic filter rod unloading and feeding device includes a frame 1, a counterweight assembly 2, a guiding assembly 3, a flipping assembly 4, a lifting power assembly 5, and a blanking assembly 6; the lifting power assembly 5 and the blanking assembly 6 are arranged in parallel on the top of the frame 1; the flipping assembly 4 is slidably installed on the outside of one side of the frame 1 through a first guiding assembly. The flipping assembly 4 includes a flipping power assembly for providing flipping power, a flipping frame, and a fixture assembly for clamping the filter rod tray; the counterweight assembly 2 is slidably installed inside the frame 1 through a second guiding assembly, and the counterweight assembly 2, the lifting power assembly 5, and the flipping assembly 4 are connected by a chain 7. Among them, the start and stop of the flipping assembly 4, the lifting power assembly 5, and the blanking assembly 6 can be controlled by an electric control cabinet circuit, and the electric control cabinet is not shown in the figure.

[0032] The counterweight assembly 2, the guiding assembly 3, the flipping assembly 4, the lifting power assembly 5, and the blanking assembly 6 in this embodiment specifically adopt the following structures:

[0033] As Figure 2 shown, the counterweight assembly 2 adopts the following structure;

[0034] The counterweight assembly 2 is composed of a counterweight frame 8, counterweight blocks 9, fixing screws 10, and chain connecting rods 11; the counterweight blocks 9 are placed inside the counterweight frame 8, and the counterweight blocks 9 are fixed relative to the counterweight frame 8 by two fixing screws 10 passing through the counterweight blocks 9 and the counterweight frame 8; two chain connecting rods 11 are symmetrically and fixedly installed on the top of the counterweight frame 8, and the chain connecting rods 11 can be hinged to one end of the chain 7, so that the counterweight assembly 2 can be connected to one end of the chain 7. The function of the counterweight assembly 2 is to balance the weight of part of the flipping assembly 4 and the filter rod tray, so that the lifting power assembly 5 can lift the flipping assembly 4 and the filter rod tray with a smaller driving force.

[0035] Furthermore, since the lifting directions of the flipping component 4 and the counterweight component 2 are opposite, in order to prevent the counterweight component 2 from colliding with the frame 1 when it moves up and down relative to the frame 1, a second guiding group is installed on both end faces inside the frame 1 and on both sides of the counterweight frame 8. As Figure 2 and Figure 7 shown, the second guiding group is composed of a guide rail 12, a horizontal guiding wheel 13 and a vertical guiding wheel 14; among them, the guide rail 12 is symmetrically installed inside the frame 1 and fixedly connected to the frame 1. The inner side surface of the guide rail 12 is a groove structure for cooperating with the horizontal guiding wheel 13 and the vertical guiding wheel 14; the horizontal guiding wheel 13 and the vertical guiding wheel 14 are cross-fixedly installed on the left and right end faces of the counterweight frame 8. Both the horizontal guiding wheel 13 and the vertical guiding wheel 14 can rotate relative to the counterweight frame 8. The horizontal guiding wheel 13 is in rolling contact with the side wall of the groove structure, and the vertical guiding wheel 14 is in rolling contact with the bottom of the groove structure, so as to guide the lifting movement of the counterweight component 2.

[0036] As Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 shown, the flipping component 4 adopts the following structure;

[0037] The flipping component 4 is composed of a flipping power component, a flipping frame 19 and a fixture component.

[0038] Among them, the flipping power component includes a motor mounting frame 16, a flipping motor 17, a flipping shaft 18 and a chain connecting rod 11; the motor mounting frame 16 is slidably installed outside one side of the frame 1 through a first guiding component. The first guiding component includes a linear guide rail 15 and a slider. The two linear guide rails 15 are installed in parallel on the frame 1. The motor mounting frame 16 is slidably installed on the linear guide rail 15 through the slider; the flipping motor 17 is fixedly installed on the top side of the motor mounting frame 16; the flipping shaft 18 is rotatably installed in the middle of the top of the motor mounting frame 16, and one end of the flipping shaft 18 is fixedly connected to the output shaft of the flipping motor 17; the chain connecting rod 11 is fixedly installed inside the top of the motor mounting frame 16. The chain connecting rod 11 can be hinged to the other end of the chain 7, so that the flipping power component, the flipping frame 19 and the fixture component can move up and down relative to the frame 1 under the drive of the lifting power component 5. The function of the flipping power component is to provide power for the flipping of the flipping frame 19 relative to the frame 1.

[0039] The flipping frame 19 is an L-shaped frame structure. One end of the L-shaped frame structure is fixedly sleeved on the flipping shaft 18 through an industrial expansion sleeve 20, and the other end is provided with a mounting plate 21 for cooperating with the installation of the fixture component.

[0040] The fixture assembly is composed of a group of vertically parallel upper clamping plates 22, lower clamping plates 23 and a group of horizontally parallel left clamping plates 24 and right clamping plates 25; among them, the lower clamping plate 23 and the left clamping plate 24 are both plate bodies that can move through linear guides and cylinders, so that the fixture assembly can clamp the filter rod tray; since the filter rods in the filter rod tray need to fall onto the blanking assembly 6 from the upper clamping plate 22 after the flipping assembly 4 is flipped on the top of the frame 1, the upper clamping plate 22 also adopts a plate body that can move through linear guides and cylinders.

[0041] Specifically, the linear guide A 28 is arranged in parallel at the lower end of the mounting plate 21. The linear guide A 28 is fixedly connected to the mounting plate 21 through a spacer block. The cylinder seat is arranged in the middle of the two linear guides A 28. The top of the cylinder seat is fixedly installed with a cylinder A 29. The output end of the cylinder A 29 is fixedly connected to the bottom of the lower clamping plate 23. The lower clamping plate 23 is slidably installed on the linear guide A 28 through a slider and vertically slides relative to the mounting plate 21 under the action of the cylinder A 29.

[0042] A cover plate support 45 for mating with the installation of the upper clamping plate 22 is provided at the top of the flipping frame 19. The cover plate support 45 is fixedly connected to the mounting plate 21. The cylinder B 27 is fixedly installed at the bottom of the cover plate support 45 and is located inside the flipping frame 19. The output end of the cylinder B 27 is fixedly connected to the tail end of the upper clamping plate 22 through an adapter seat 30. The middle end of the upper clamping plate 22 is slidably connected to the two linear guides B 26 through sliders. The two linear guides B 26 are fixedly installed on the top surface of the cover plate support 45 and are symmetrically arranged with the cylinder B 27 as the center. The upper clamping plate 22 horizontally slides back and forth relative to the mounting plate 21 under the action of the cylinder B 27.

[0043] The right clamping plate 25 is fixedly installed in the middle of the right side of the mounting plate 21. The end of the left clamping plate 24 close to the cylinder C 32 is hinged to the output end of the cylinder C 32. The cylinder C 32 is fixedly connected to the mounting plate 21 through the hinge seat at the tail end. The bottom of the left clamping plate 24 is slidably connected to the direct guide C 31 through a slider. The direct guide C 31 is fixedly installed in the middle of the left side of the mounting plate 21.

[0044] Furthermore, in order to limit the maximum displacement of the lower clamping plate 23 and the left clamping plate 24, a limit baffle 34 is installed on the front side of the mounting plate 21 through a support rod 33. The limit baffle 34 can limit the maximum displacement of the lower clamping plate 23 and the left clamping plate 24, preventing damage to the filter rod tray when the fixture assembly clamps the filter rod tray.

[0045] As Figure 1 、 Figure 7 shown, the lifting power assembly 5 adopts the following structure;

[0046] The lifting power assembly 5 is composed of a driving motor 35, a torque arm 36, a torque arm mounting seat 37, a driving shaft 38 and a sprocket 39; the seat bearing is mounted on the top of the frame 1 through a fixing block, the driving shaft 38 is rotatably mounted on the top of the frame 1 through two seat bearings, one end of the driving shaft 38 is fixedly connected to the output end of the driving motor 35, and the driving motor 35 is connected to the torque arm mounting seat 37 mounted on the frame 1 through the torque arm 36 to fix its position; there are two sprockets 39, two sprockets 39 are fixedly mounted on the driving shaft 38 and connected to the driving shaft 38 key, a circular nut and a stop washer are provided on the side of the sprocket 39 close to the seat bearing, and the sprocket 39 is connected to the chain 7 in a transmission manner. The function of the lifting power assembly 5 is to provide power for the lifting and lowering of the flip assembly 4 relative to the frame 1.

[0047] like Figure 1 , Figure 7 and Figure 8 As shown, the blanking assembly 6 adopts the following structure;

[0048] The blanking assembly 6 includes a side panel 40, a back panel 41, a horizontal conveyor 42 and a door panel assembly 43; the side panel 40, two back panels 41 and the door panel assembly 43 form a cavity structure with a top opening, the horizontal conveyor 42 is located at the bottom of the cavity structure, and the cavity structure can receive the filter rod dropped from the filter rod tray through the top opening. A diversion assembly 44 capable of diverting the filter rod is fixedly installed inside the cavity structure, and the filter rod falls onto the horizontal conveyor 42 after being diverted by the diversion assembly 44.

[0049] The working principle of the automatic unloading and feeding device for rod-type materials is as follows:

[0050] like Figure 1 and Figure 9 As shown, first, the driving motor 35 of the lifting power assembly 5 is started, and the driving motor 35 drives the driving shaft 38 and the sprocket 39 on the driving shaft 38 to rotate. The flip assembly 4 descends from the top of the frame 1 along the two linear guide rails 15 of the first guide assembly under the action of its own gravity, and stops after descending until the clamp assembly of the flip assembly 4 and the filter rod plate are at the same height. At the same time, the counterweight assembly 2 rises along the guide rail 12 of the second guide assembly inside the frame 1 under the action of the traction force of the chain 7.

[0051] Then the clamp assembly of the flipping assembly 4 is actuated, and the left clamping plate 24 and the lower clamping plate 23 of the clamping assembly move on the linear guide C31 and the linear guide B26 respectively under the action of the cylinder C32 and the cylinder B27, and the left clamping plate 24 cooperates with the right clamping plate 25 to clamp the filter rod plate in the horizontal direction, and the lower clamping plate 23 cooperates with the upper clamping plate 22 to clamp the filter rod plate in the vertical direction.

[0052] Then, the drive motor 35 of the lifting power assembly 5 starts again. The drive motor 35 drives the drive shaft 38 and the sprocket 39 on the drive shaft 38 to rotate in the reverse direction. Under the action of its own gravity, the counterweight assembly 2 descends along the guide rail 12 passing through the second guiding assembly from the top inside the frame 1. At the same time, under the traction of the chain 7, the flipping assembly 4 ascends from the bottom of the frame 1 along the two linear guide rails 15 passing through the first guiding assembly to the top outside the frame 1.

[0053] Then, the flipping motor 17 of the flipping power assembly starts. The flipping motor 17 drives the flipping shaft 18 to rotate, so that the flipping frame 19, the fixture assembly, and the filter rod tray rotate 180° with the flipping shaft 18 as the center at the top of the frame 1. At this time, the lower clamping plate 23, the filter rod tray, the upper clamping plate 22, and the blanking assembly 6 of the fixture assembly are located on the same vertical axis from high to low. Under the action of the cylinder A29, the upper clamping plate 22 slides horizontally along the linear guide rail A28 to the side away from the blanking assembly 6. The filter rods in the filter rod tray enter the cavity structure from the top opening of the blanking assembly 6. Under the action of the shunting assembly 44, the filter rods are shunted in the cavity structure and finally horizontally conveyed to the next process by the horizontal conveyor 42.

[0054] Through the cycle of the above steps, smooth feeding, lifting to an appropriate height, and rapid flipping and feeding are realized within a limited space, ensuring safe production and saving manpower and material resources to the greatest extent. This automatic unloading and feeding device for rod-shaped materials is not only applicable to the feeding of filter rods in the tobacco industry but also can be used for the feeding of rod-shaped materials in other industries.

[0055] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
