Description

Technical Field

[0001] The invention relates to the technical field of tobacco machinery, and in particular to a lifting and glue supplying mechanism of a connecting and loading machine. Background Art

[0002] The YJ29 tipping paper glue supply system adopts continuous and uninterrupted glue supply. Figure 1 The schematic diagram of the structure of the existing tipping paper glue supply system is as follows: Figure 1 As shown, the system includes a glue applicator 1, a glue return tank 2, a motor 3, a glue pump 4, a glue supply tube 5, a glue barrel 6 and a glue return tube 7; wherein the motor 3 drives the glue pump 4 to run continuously, and the glue in the glue barrel 6 is sent to the glue applicator 1 through the glue supply tube 5, and the excess glue flows back into the glue barrel through the glue return tank 2 and the glue return tube 7. However, during the production process, this glue supply method has the following problems:

[0003] 1. During the reflux process, the glue liquid is exposed to the air, causing the glue liquid to lose moisture, and the amount of impurities such as glue particles and dust to increase. The refluxed glue liquid brings a small amount of dried glue particles in the glue applicator and the glue return pipe into the glue liquid barrel, and generates a large number of bubble groups when flowing into the glue liquid barrel, which also reduces the moisture content of the glue liquid, and easily forms dry glue particles around the bubble groups on the surface of the glue liquid.

[0004] 2. This glue supply method requires continuous and uninterrupted glue supply, but there are intermittent flow interruptions in the actual process. Under the uninterrupted glue supply method, the glue pump runs at high speed for a long time, and the gears, pins and other parts of the glue pump will be worn. At this time, if the bubble group and glue particles in the glue liquid enter the glue pump, it will reduce the output pressure and block the glue hole, so that the glue pump can supply less glue. In severe cases, the glue supply will be interrupted. Intermittent flow interruptions in the glue supply are prone to air leakage and cigarette drop, and the detector cannot completely detect and remove them, causing defective cigarettes to enter the next process.

[0053] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0054] like Figures 2 to 9As shown, an embodiment of the present invention provides a lifting and glue supply mechanism of a mounting machine, which includes a box body 100, a rotating structure 200, a rocker arm 500, a lifting structure, a tray 400 and a glue box 600; wherein, a guide groove is provided on the box body 100, and the guide groove extends in the longitudinal direction (vertical direction perpendicular to the ground) of the box body 100; the rotating structure 200 is rotatably connected to the box body 100; one end of the rocker arm 500 is fixedly connected to the rotating structure 200, and the other end of the rocker arm 500 is provided with a waist-shaped hole 510; the lifting structure is slidably connected to the guide groove, and one end of the lifting structure is provided with a guide shaft 331, and the guide shaft 331 is slidably set in the waist-shaped hole 510; the tray 400 is fixedly connected to the other end of the lifting structure; the glue box 600 is set on the tray 400.

[0055] When the rotating structure 200 is rotated, the swing rod 500 can be driven to rotate together. Figure 3 As shown, when the rotating structure 200 is rotated counterclockwise, the rocker arm 500 rotates counterclockwise synchronously, and the lifting structure can only perform translational motion in the guide groove, and cannot rotate with the rocker arm 500. Therefore, the rotational motion of the rocker arm 500 can be converted into the longitudinal translational motion of the lifting structure through the sliding cooperation between the waist-shaped hole 510 on the rocker arm 500 and the guide shaft 331 on the lifting structure, so that the lifting structure can drive the tray 400 to rise or fall.

[0056] It is understandable that the glue box 600 is filled with glue during operation. When the glue box 600 on the tray 400 rises to a preset position along with the lifting structure, part of the roller at the preset position can be immersed in the glue, and gluing can be achieved by rotating the roller.

[0057] Compared with the prior art, the lifting and glue supply mechanism of the mounting machine provided in this embodiment eliminates the pipeline used to transport the glue in the prior art. The roller is directly in contact with the glue in the glue box 600 through the lifting structure, which completely avoids the problem of bubbles generated by transporting the glue through the pipeline. At the same time, by storing the glue in the glue box 600, the problem of glue flow interruption is also avoided, thereby ensuring the quality of gluing.

[0058] In this embodiment, a pneumatic pump without a gear assembly can be used to deliver oil to the glue box 600 to replace the existing glue pump, thereby avoiding problems such as gear wear and aging.

[0059] Further, if Figures 3 to 5 As shown, the rotating structure 200 includes a sleeve shaft 210 and a pull rod 220. The sleeve shaft 210 is a hollow structure. The sleeve shaft 210 is rotatably sleeved on the pull rod 220. The pull rod 220 is arranged on the box body 100. One end of the swing rod 500 is fixedly connected to the sleeve shaft 210.

[0060] The axis of the pull rod 220 is perpendicular to the surface of the box 100 , and the pull rod 220 will not shake radially. The sleeve shaft 210 sleeved on the pull rod 220 can only rotate, so that the lifting structure can be driven to rise and fall by the rotation of the sleeve shaft 210 .

[0061] In order to facilitate the rotation of the sleeve shaft 210 , a handle 211 may be fixedly provided on the sleeve shaft 210 .

[0062] Further, if Figures 3 to 5 As shown, the glue supply mechanism also includes a latch 120, and a receiving groove 130 is provided in the box body 100, and the latch 120 is movably arranged in the receiving groove 130; one end of the latch 120 is fixedly connected to the pull rod 220, and the other end of the latch 120 is provided with a clamping portion 121 for positioning the lifting structure; the rotating structure 200 also includes a spring 230, and a limiting member 221 is provided on the end of the pull rod 220 away from the latch 120, the spring 230 is sleeved on the pull rod 220, and the two ends of the spring 230 are respectively fixedly connected to the sleeve rod shaft 210 and the limiting member 221.

[0063] The depth of the receiving groove 130 is greater than or equal to the thickness of the latch 120. When the latch 120 abuts against the bottom surface of the receiving groove 130, the latch 120 can be completely received in the receiving groove 130 without protruding from the surface around the opening of the receiving groove 130. When the latch 120 needs to be engaged with the positioning lifting structure, the latch 120 can be moved away from the bottom surface of the receiving groove 130 so that the latch 120 protrudes from the surface around the opening of the receiving groove 130. It can be understood that when a part of the structure of the latch 120 protrudes from the receiving groove 130, the part can form a step structure with the surface around the opening of the receiving groove 130, so that the lifting structure can be engaged and positioned on the step structure, thereby preventing the lifting structure from falling back.

[0064] It should be noted that the movement of the tongue 120 can be achieved by pulling the pull rod 220. Specifically, when the pull rod 220 is pushed in the direction of the box body 100, the pull rod 220 can push the tongue 120 into the receiving groove 130. At this time, there is no interference on the movement trajectory of the lifting structure, thereby facilitating the movement of the lifting structure; and when the pull rod 220 is pulled in the direction away from the box body 100, part of the structure of the tongue 120 can be pulled out of the receiving groove 130 to form the above-mentioned step structure, so that the lifting structure can be positioned by the step structure.

[0065] In order to realize that part of the structure on the latch tongue 120 can be automatically moved out of the accommodating groove 130 to automatically form the above-mentioned step structure for easy operation, in this embodiment, a spring 230 can be set on the end of the pull rod 220 away from the box body 100, and the spring 230 is always in a stretched state. When the lifting structure rises, the limit member 221 can be pushed by an appropriate external force to push the latch tongue 120 into the accommodating groove 130 through the pull rod 220. At this time, the lifting structure can continue to rise without being blocked by the latch tongue 120. At the same time, the latch tongue 120 can be blocked by the lifting structure and remain in the accommodating groove 130; and when the lifting structure passes over the latch tongue 120, the latch tongue 120 loses the blocking force of the lifting structure. At this time, the latch tongue 120 is protruded from the surface around the opening of the accommodating groove 130 by the tension of the spring, thereby automatically forming the above-mentioned step structure, so that the lifting structure can be stuck on the step structure to achieve positioning and prevent the lifting structure from falling back.

[0066] In order to improve the comfort when pushing the pull rod 220 , the limiting member 221 may be spherical, and the diameter of the sphere is greater than the diameter of the pull rod 220 .

[0067] Further, if Figure 8 As shown, an inclined surface 122 is provided on the clamping portion 121, and the thickness of the clamping portion 121 gradually increases in the ascending direction of the lifting structure, that is, the inclined surface 122 can make the upper thickness of the clamping portion 121 greater than the lower thickness of the clamping portion 121.

[0068] When the latch tongue 120 is in operation, the upper portion of the latch portion 121 protrudes from the accommodating groove 130, while the lower edge of the latch portion 121 is flush with the surface where the opening of the accommodating groove 130 is located, or the lower edge of the latch portion 121 is still located in the accommodating groove 130, but does not protrude from the surface where the opening of the accommodating groove 130 is located. Therefore, when the lifting structure rises to the position of the latch tongue 120, there is no need to push the pull rod 220 by external force, but the lifting structure is directly controlled to rise. When the lifting structure contacts the inclined surface 122, the latch tongue 120 can be gradually squeezed into the accommodating groove 130 by the push of the lifting structure and the action of its own inclined surface 122, so that there is no need to apply external force to push the pull rod 220, thereby realizing the automatic latching and positioning of the lifting structure by the latch tongue 120.

[0069] Further, if Figure 3 and Figure 7 As shown, the lifting structure includes a guide block 330 and a guide rod 310; a guide hole is provided on the box body 100, one end of the guide rod 310 passes through the guide hole and is fixedly connected to the guide block 330, and the guide block 330 is slidably matched with the guide groove; the other end of the guide rod 310 is fixedly connected to the tray 400, and the guide shaft 331 is provided on the guide block 330.

[0070] The guide block 330 can only move in the guide groove, that is, the surface of the guide block 330 does not protrude from the surface where the guide groove opening is located. At the same time, the swing rod 500 and the tongue 120 are integrated in the guide groove. The box body 100 can be provided with a cover plate 110, and the cover plate 110 can seal the guide block 330, the swing rod 500 and the tongue 120 in the guide groove. Figure 2 As shown, the above-mentioned moving parts are prevented from being contaminated or bumped, thereby ensuring the reliability of the operation of the glue supply mechanism.

[0071] Among them, two guide rods 310 can be arranged in parallel to prevent rotation and ensure the smoothness of lifting.

[0072] Further, if Figure 4 As shown, in order to facilitate the connection between the lifting structure and the tray 400, the lifting structure further includes a bracket 320, and one end of the guide rod 310 away from the guide block 330 is fixedly connected to the bracket 320, and the bracket 320 is fixedly connected to the tray 400.

[0073] The tray 400 is provided with a connecting flange, which can be connected to the bracket 320 by a connecting member such as a bolt.

[0074] Further, if Figure 4 and Figure 5 As shown, in order to realize automatic detection and monitoring of the ascending and descending positions of the lifting structure, the lifting structure may further include a detection device 700, which is fixedly arranged on the bracket 320. The detection device 700 may be a proximity switch. When the plastic box 600 is not raised to the right position, the proximity switch may send a signal to prohibit starting the device, and the device cannot operate, so as to avoid producing defective cigarettes.

[0075] Further, if Figure 4 and Figure 5 As shown, the tray 400 includes a main body 410 and a card plate 420, the card plate 420 is rotatably connected to the main body 410, one end of the card plate 420 extends out of the main body 410, and the other end of the card plate 420 is provided with a protrusion 421, the main body 410 is provided with a through hole, the protrusion 421 is telescopically arranged in the through hole, and the bottom of the plastic box 600 is provided with a card slot, which cooperates with the protrusion 421.

[0076] It should be noted that the middle part of the card plate 420 is rotatably connected to the main body 410. Specifically, the card plate 420 can be rotatably connected to the main body 410 through a pin 423, thereby allowing the card plate 420 to form a lever structure. When one end of the card plate 420 extending out of the main body 410 is pushed, the card plate 420 rotates around the pin 423, so that the end of the card plate 420 with a protrusion 421 rotates together, so that the protrusion 421 is inserted into or removed from the through hole on the main body 410.

[0077] In order to realize the automatic clamping of the cardboard 420 to the plastic box 600, a torsion spring can be sleeved on the pin 423. In the natural state, the torsion spring can make the end of the cardboard 420 with the protrusion 421 abut against the body 410, so that the protrusion 421 can always be kept in the state of passing through the through hole. At the same time, the protrusion 421 can also be provided with a guiding inclined surface 422, such as Figure 3 and Fig. 9 As shown, when the plastic box 600 slides in from one end of the body 410, the plastic box 600 first contacts the guide slope 422, and the projection 421 is squeezed out of the through hole by the action of the guide slope 422, so that the plastic box 600 continues to slide forward. When the card slot at the bottom of the plastic box 600 is aligned with the projection 421, the projection 421 is no longer squeezed by the plastic box 600, and the projection 421 is automatically snapped into the card slot by the restoring force of the torsion spring, thereby realizing the positioning of the plastic box 600.

[0078] Further, if Fig. 9 As shown, a slide groove 610 is provided on the plastic box 600 , and the slide groove 610 is slidably matched with the body 410 .

[0079] The slide groove 610 can be sleeved on the edge of the body 410 and slide on the body 410 under the guidance of the slide groove 610, thereby preventing the plastic box 600 from shaking in other directions and ensuring the stability of the plastic box 600.

[0080] Further, if Figure 4 As shown, a limit baffle 430 may be further provided on the tray 400 , and the limit baffle 430 may prevent the plastic box 600 from excessively sliding on the body 410 , so as to ensure the placement accuracy of the plastic box 600 on the tray 400 .

[0081] The lifting and glue supplying mechanism of the mounting machine provided in the embodiment of the present invention eliminates the pipeline used for conveying glue in the prior art. The roller is directly in contact with the glue in the glue box through the lifting structure, which completely avoids the problem of bubbles generated by conveying glue through the pipeline. At the same time, by storing the glue in the glue box, the problem of glue flow interruption is also avoided, thereby ensuring the quality of gluing.

[0082] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the present invention is not limited to the scope of implementation shown in the drawings. Any changes made according to the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the description and drawings, should be within the protection scope of the present invention.
