Description

Technical Field

[0001] The present invention relates to the field of beer can assembly, and particularly to a beer can assembling machine. Background Art

[0002] Beer is an alcoholic beverage brewed mainly from wheat malt and barley malt, with hops added, through liquid gelatinization and saccharification, and then through liquid fermentation. Raw beer is one type of beer among many beer varieties, which is the original young beer directly filled from the fermentation tank, with a delicious and peerless taste, being authentic and pure. Currently, most raw beers are filled into cans, and there is a certain amount of compressed air in the beer cans. When the beer can is opened, air pressure will be generated inside the beer can to draw out the beer. This way of storing beer can maintain the freshness of the beer.

[0003] This kind of beer can is stored with large cans and small cans separated. The small cans store compressed air, and the large cans are filled with beer. After assembling the large cans and small cans together, air is injected into the small cans, and the beer is filled into the large cans to complete the filling of the beer. In the prior art, when assembling the large cans and small cans, generally, special glue is brushed on the bottom of the small cans, and then the small cans are glued to the center position at the inner bottom of the large cans. After the special glue dries, the next step is carried out. However, the existing glue brushing method has the following defects:

[0004] 1. There is only a simple contact between the glue brush and the bottom of the small can, resulting in uneven and insufficient glue brushing, which may cause insufficient and weak gluing between the large can and the small can;

[0005] 2. Excess special glue may overflow from the glue brush and stick to the outer wall of the lower part of the small can, resulting in residual glue sticking to the outer wall of the small can, and it is not easy for the staff to clean.

[0006] These defects will lead to poor assembly quality of the beer cans, thus affecting subsequent beer filling. Summary of the Invention

[0007] In view of this, the present invention provides a beer can assembling machine, which can brush the glue onto the bottom of the small can more fully, evenly, and clean the residual glue on the outer wall of the small can more quickly, improving the assembly quality of the beer cans.

[0008] The technical solution is as follows: A beer can assembling machine includes a base, a motor, a transmission assembly, a clamping mechanism, a guiding mechanism, and a glue brushing mechanism.

[0010] Furthermore, an injection hole is provided on the glue box.

[0011] Furthermore, both of the two guiding rods are of hollow structure.

[0012] Furthermore, the glue brushing mechanism includes a mounting tube, a magnetic rod, a mounting plate, a glue brush, and a connecting hose. Mounting tubes are slidably connected to the outer walls of both of the two guiding rods. The other end of the vertical spring is rotatably connected to the mounting tube.

Magnetic rods are fixedly connected to the sides of the lower parts of the two connecting frames away from the mounting plate, and the magnetic rods are slidably connected to the guiding grooves. Mounting plates are fixedly connected to the lower parts of both of the two mounting tubes. Glue brushes are rotatably connected to both of the two mounting plates. The small beer can is located directly above the glue brush. One end of two connecting hoses is communicated with the glue box. The connecting hose is fixedly connected to the connecting frame, and the connecting hose passes through the guiding rod. The other end of the connecting hose is communicated with the glue brush.

[0013] Furthermore, a rotating mechanism is further included. Rotating mechanisms are provided on both of the two glue brushing mechanisms. The rotating mechanism includes a touch rod, a horizontal spring, a transmission frame, a rack, and a gear. A number of touch rods are slidably connected to the lower parts of both of the two mounting tubes. A horizontal spring is connected between each touch rod and the mounting tube. Transmission frames are fixedly connected between the number of touch rods located on the same mounting tube. The transmission frame is slidably connected to the mounting plate. Racks are fixedly connected to the sides of the two transmission frames away from the mounting tube. Gears are rotatably connected to both of the two mounting plates. The gear is fixedly connected to the bottom of the glue brush, and the rack is meshed with the gear.

[0014] Furthermore, it also includes a scraping mechanism, and the two glue brushing mechanisms are each provided with a scraping mechanism, and the scraping mechanism includes an extrusion spring, a hydraulic cylinder, a piston ring, an annular cylinder, a magnetic piston, an iron ring, a scraper and a liquid hose, one end of the extrusion spring is fixedly connected to the upper part of the two mounting tubes, and the two mounting tubes are slidably connected to the hydraulic cylinder, the hydraulic cylinder is located above the mounting plate, the other end of the extrusion spring is fixedly connected to the hydraulic cylinder, the two hydraulic cylinders are slidably connected with piston rings, the piston ring is slidably connected to the mounting tube, the piston ring is located above the magnetic rod, the piston ring is made of iron, the annular cylinder is fixedly connected to the mounting plate, the glue brush is located in the annular cylinder, the magnetic piston is slidably connected to the inner wall of the annular cylinder, the iron ring is slidably connected to the outer wall of the annular cylinder, the iron ring is made of iron, the scraper is fixedly connected to the top of the iron ring, one end of the liquid hose is fixedly connected to the hydraulic cylinder, the other end of the liquid hose is fixedly connected to the annular cylinder, and the hydraulic cylinder is connected to the annular cylinder through the liquid hose.

[0015] Furthermore, it also includes a cleaning mechanism, which is arranged on the annular cylinder, and includes a mounting rod and a cleaning knife. A wave groove is opened on the outer wall of the annular cylinder, and two mounting rods are slidably connected to the scraper. The iron ring is located between the two mounting rods, and the two mounting rods are slidably connected to the wave groove. The tops of the two mounting rods are fixedly connected with cleaning knives, and the scraper is located between the two cleaning knives, and the scraper is in contact with both cleaning knives.

[0016] The beneficial effects are:

[0017] 1. The clamping mechanism will drive the two small beer cans to move downward. The small beer cans will contact the glue brush when moving downward, and push the glue brush and the mounting plate to move downward together. At the same time, the glue brush will apply special glue to the bottom of the small beer cans. The glue brush and the mounting plate will continue to move downward and rotate along the guide groove and lose contact with the bottom of the small beer cans. The small beer cans will continue to move downward and contact the inner bottom of the large beer can. The special glue will stick the small beer cans and the large beer cans together, thereby completing the rapid assembly of the beer cans.

[0018] 2. The downward movement of the mounting plate will drive several trigger rods to move downward. When the trigger rods move downward, they will continuously contact and be squeezed by the magnetic rods, thereby driving the transmission frame and the rack to move together, causing the rubber brush to rotate. When the trigger rods no longer squeeze the magnetic rods, the transmission frame and the rack will reset to drive the rubber brush to rotate in the opposite direction, causing the rubber brush to rotate back and forth. The reciprocating rotation of the rubber brush will apply the special glue more evenly and fully to the bottom of the small beer can, making the small beer can and the large beer can stick more firmly.

[0019] 3. When the installation pipe moves downward, it will drive the hydraulic cylinder and piston ring to move downward together. When the piston ring moves downward, it will be blocked by the magnetic rod. When the hydraulic cylinder continues to move downward, it will squeeze the hydraulic oil into the annular cylinder and push the magnetic piston to move quickly. The quick movement of the magnetic piston will drive the iron ring and the scraper to rotate around the lower part of the outer wall of the small beer can for one circle, scraping off the special glue overflowing from the lower part of the outer wall of the small beer can, preventing the excess special glue on the small beer can from being applied to the large beer can subsequently and affecting the subsequent beer filling, thereby quickly cleaning up the excess special glue on the small beer can.

[0020] 4. The rotation of the scraper will drive the rotation of the two installation rods, and then drive the rotation of the two cleaning knives. While the two installation rods are rotating, they will reciprocate up and down along the wave-shaped groove, and then drive the two cleaning knives to reciprocate up and down. The reciprocating up and down movement of the two cleaning knives will scrape off the residual glue on the scraper, so that the scraper can more quickly scrape off the excess special glue on the outer wall of the small beer can, thereby improving the efficiency of cleaning the residual glue.

[0038] Embodiment 1

[0039] A beer can assembling machine, as Figures 1 - 7As shown in the figure, it includes a base 1, a motor 2, a transmission component 3, a clamping mechanism 5, a guiding mechanism and a glue brushing mechanism. The motor 2 is connected to the upper side of the base 1 by bolts. The transmission component 3 is connected to the base 1 by bolts, and the input shaft of the transmission component 3 is fixedly connected to the output shaft of the motor 2. A placing disc is provided on the output shaft of the transmission component 3. A number of large beer cans 4 are placed on the placing disc of the transmission component 3. The clamping mechanism 5 is connected to the upper side of the base 1 by bolts. A number of small beer cans 6 are clamped on the clamping mechanism 5. The guiding mechanism is arranged on the base 1, and two glue brushing mechanisms are arranged on the guiding mechanism.

[0040] The guiding mechanism includes a mounting disc 71, a connecting frame 72, a glue box 73, a guiding rod 74 and a vertical spring 75. The mounting disc 71 is connected to the upper side of the base 1 by bolts. The upper part of the mounting disc 71 is located above the placing disc of the transmission component 3. Two connecting frames 72 are connected to the mounting disc 71 by bolts. The two connecting frames 72 are symmetrically arranged. A glue box 73 is connected between the two connecting frames 72 by bolts. Guiding rods 74 are connected to both of the two connecting frames 72 by bolts. One end of a vertical spring 75 is connected to both of the two connecting frames 72 by hooks. The vertical spring 75 is sleeved on the guiding rod 74.

[0041] An injection hole is opened on the glue box 73.

[0042] Both of the two guiding rods 74 are of hollow structure.

[0043] The glue brushing mechanism includes a mounting tube 81, a magnetic rod 83, a mounting plate 84, a glue brush 85 and a connecting hose 86. Mounting tubes 81 are slidably connected to the outer walls of both of the two guiding rods 74. The other end of the vertical spring 75 is rotatably connected to the mounting tube 81. Guide grooves 82 are opened on both of the two mounting tubes 81. Magnetic rods 83 are connected to the sides of the lower parts of the two connecting frames 72 far away from the mounting disc 71 by bolts. The magnetic rods 83 are horizontally arranged. The magnetic rods 83 are slidably connected to the guide grooves 82. Mounting plates 84, mounting plates 84 are connected to the lower parts of both of the two mounting tubes 81 by bolts. Glue brushes 85 are rotatably connected to both of the two mounting plates 84. The small beer can 6 is located directly above the glue brush 85. One ends of two connecting hoses 86 are communicated with the glue box 73. The connecting hose 86 is made of a soft material. The connecting hose 86 is fixedly connected to the connecting frame 72, and the connecting hose 86 passes through the guiding rod 74. The other end of the connecting hose 86 is communicated with the glue brush 85.

[0044] At first, two small beer cans 6 are clamped on the clamping mechanism 5, and several large beer cans 4 are placed on the transmission assembly 3. The small beer cans 6 are located above two of the large beer cans 4. The staff first adds special glue into the glue box 73, and then starts the motor 2 and the clamping mechanism 5. The staff adjusts the output shaft of the motor 2 to rotate intermittently. The special glue in the glue box 73 will flow into the two glue brushes 85 through two connecting hoses 86 and then overflow from the two glue brushes 85. The clamping mechanism 5 will drive the two small beer cans 6 to move downward. The downward movement of the small beer cans 6 will contact the glue brushes 85 and push the glue brushes 85 downward. At the same time, the glue brushes 85 will apply the special glue to the bottom of the small beer cans 6. The downward movement of the glue brushes 85 will drive the mounting pipe 81 and the mounting plate 84 to move downward together, and the vertical spring 75 is stretched. Since the magnetic rod 83 is fixed and the magnetic rod 83 is slidably connected to the guide groove 82, the mounting pipe 81 will move downward and rotate. The rotation of the mounting pipe 81 will drive the mounting plate 84 and the glue brush 85 to rotate together. The rotation of the glue brush 85 will disengage from the bottom of the small beer cans 6. At this time, the small beer cans 6 will continue to move downward, and the mounting plate 84 will contact the side of the small beer cans 6. The continuous downward movement of the small beer cans 6 will disengage from the mounting plate 84. The reset of the vertical spring 75 will drive the mounting pipe 81, the mounting plate 84 and the glue brush 85 to rotate in the reverse direction and reset upward. The continuous downward movement of the small beer cans 6 will contact the inner bottom of the large beer cans 4, and the special glue will stick the small beer cans 6 and the large beer cans 4 together, thus completing the assembly of the beer cans. Then, the rotation of the output shaft of the motor 2 will drive the transmission assembly 3 to rotate, and the rotation of the transmission assembly 3 will drive the large beer cans 4 to rotate, transporting the unassembled large beer cans 4 to directly below the glue brush 85. At the same time, the clamping mechanism 5 will rotate and clamp a new small beer can 6 directly above the glue brush 85. Repeat this process to quickly assemble the large beer cans 4 and the small beer cans 6.

[0045] Embodiment 2

[0046] Based on Embodiment 1, as Figures 2 - 9As shown in the figure, it further includes a rotating mechanism. The rotating mechanism is provided on both of the two glue brushing mechanisms. The rotating mechanism includes a trigger rod 91, a horizontal spring 92, a transmission frame 93, a rack 94 and a gear 95. Four trigger rods 91 are slidably connected to the lower part of each of the two mounting tubes 81. The four trigger rods 91 are all horizontally arranged. A horizontal spring 92 is connected between each trigger rod 91 and the mounting tube 81 through a hook. The horizontal spring 92 is sleeved on the trigger rod 91. A transmission frame 93 is fixedly connected between several trigger rods 91 located on the same mounting tube 81. The transmission frame 93 is slidably connected to the mounting plate 84. A rack 94 is bolted to one side of each of the two transmission frames 93 away from the mounting tube 81. A gear 95 is rotatably connected to each of the two mounting plates 84. The gear 95 is fixedly connected to the bottom of the glue brush 85. The rack 94 meshes with the gear 95.

[0047] When the mounting plate 84 moves downward, it will drive the transmission frame 93 to move downward. When the mounting tube 81 moves downward, it will drive several trigger rods 91, the transmission frame 93 and the rack 94 to move downward together. When the mounting plate 84 moves downward, it will drive the gear 95 to move downward. When several trigger rods 91 move downward, they will continuously contact the magnetic rod 83 and be squeezed to move away from the connecting frame 72. The horizontal spring 92 is continuously compressed. When the trigger rod 91 moves away from the connecting frame 72, it will drive the transmission frame 93 to move. When the transmission frame 93 moves, it will drive the rack 94 to move. When the rack 94 moves, it will drive the gear 95 meshing with it to rotate. When the gear 95 rotates, it will drive the glue brush 85 to rotate. When the trigger rod 91 no longer squeezes the magnetic rod 83, the reset of the horizontal spring 92 will drive the trigger rod 91 and the transmission frame 93 to reset together. When the transmission frame 93 resets, it will drive the rack 94 to reset. When the rack 94 resets, it will drive the gear 95 and the glue brush 85 to rotate in the reverse direction, causing the glue brush 85 to rotate reciprocally, so that the special glue can be applied to the bottom of the small beer can 6 more evenly and fully; when the mounting plate 84 resets upward, it will drive the transmission frame 93 to reset upward. When the mounting tube 81 resets upward, it will drive several trigger rods 91, the transmission frame 93 and the rack 94 to reset upward together. When several trigger rods 91 reset upward, they will continuously contact the magnetic rod 83 and be squeezed. The horizontal spring 92 is continuously compressed. When the trigger rod 91 no longer squeezes the magnetic rod 83, the reset of the horizontal spring 92 will drive the trigger rod 91 and the transmission frame 93 to reset together. When the mounting plate 84 resets upward, it will drive the gear 95 to reset upward.

[0048] Embodiment 3

[0049] On the basis of Embodiment 2, as Figures 2 - 14As shown in the figure, it further includes a rubber scraping mechanism. The rubber scraping mechanism is provided on both of the two glue brushing mechanisms. The rubber scraping mechanism includes a compression spring 101, a hydraulic cylinder 102, a piston ring 103, an annular cylinder 104, a magnetic piston 105, an iron ring 106, a scraper 107 and a liquid passing hose 108. One end of the compression spring 101 is connected to the upper part of each of the two mounting pipes 81 through a hook. A hydraulic cylinder 102 is slidably connected to each of the two mounting pipes 81. The hydraulic cylinder 102 is located above the mounting plate 84. The other end of the compression spring 101 is fixedly connected to the hydraulic cylinder 102. A piston ring 103 is slidably connected to each of the two hydraulic cylinders 102. The piston ring 103 is slidably connected to the mounting pipe 81. The piston ring 103 is located above the magnetic rod 83. The piston ring 103 is made of iron. The annular cylinder 104 is connected to the mounting plate 84 by bolts. The glue brush 85 is located inside the annular cylinder 104. The magnetic piston 105 is slidably connected to the inner wall of the annular cylinder 104. The iron ring 106 is slidably connected to the outer wall of the annular cylinder 104. The iron ring 106 is made of iron. The scraper 107 is connected to the top of the iron ring 106 by bolts. One end of the liquid passing hose 108 is fixedly connected to the hydraulic cylinder 102. The other end of the liquid passing hose 108 is fixedly connected to the annular cylinder 104. The hydraulic cylinder 102 and the annular cylinder 104 are communicated through the liquid passing hose 108.

[0050] Initially, the hydraulic cylinder 102 and the liquid hose 108 are filled with hydraulic oil. The small beer can 6 moves downward and contacts the scraper 107. The mounting tube 81 moves downward and drives the hydraulic cylinder 102 downward through the extrusion spring 101. The hydraulic cylinder 102 moves downward and drives the piston ring 103 and the liquid hose 108 to move downward together. The mounting plate 84 moves downward and drives the annular cylinder 104 to move downward. The annular cylinder 104 moves downward and drives the magnetic piston 105, the iron ring 106 and the scraper 107 to move downward together. The piston ring 103 moves downward. The hydraulic cylinder 102 will contact the magnetic rod 83 and be supported by the magnetic rod 83. At this time, the hydraulic cylinder 102 continues to move downward to squeeze the hydraulic oil, so that the hydraulic oil in the hydraulic cylinder 102 flows into the liquid hose 108, and the hydraulic oil in the liquid hose 108 flows into the annular cylinder 104 and pushes the magnetic piston 105 to move quickly. Since the iron ring 106 is made of iron, the rapid movement of the magnetic piston 105 will drive the iron ring 106 to move quickly, and the rapid movement of the iron ring 106 will drive the scraper 107 to rotate along the lower part of the outer wall of the small beer can 6, so as to remove the overflowed special beer can 6. The glue is scraped off to prevent the subsequent excess special glue of the small beer can 6 from being applied to the large beer can 4, which affects the subsequent beer filling, so that the excess special glue of the small beer can 6 can be quickly cleaned up, and the hydraulic cylinder 102 continues to move downward and will be supported by the piston ring 103 and will no longer move. The installation tube 81 continues to move downward and the extrusion spring 101 will be compressed; when the installation tube 81 moves upward, the extrusion spring 101 will no longer be compressed, and the extrusion spring 101 will reset. Since the piston ring 103 is made of iron, the magnetic rod 83 will absorb the piston ring 103, and the installation tube 81 continues to move upward The hydraulic cylinder 102 is driven upward by the extrusion spring 101. The upward movement of the hydraulic cylinder 102 will draw the hydraulic oil. The hydraulic oil in the annular cylinder 104 will flow into the liquid hose 108. The hydraulic oil in the liquid hose 108 will flow into the hydraulic cylinder 102. The magnetic piston 105 will reset under the action of the pressure in the annular cylinder 104. The reset of the magnetic piston 105 will drive the iron ring 106 and the scraper 107 to reset together. The hydraulic cylinder 102 continues to move upward to drive the piston ring 103 to move upward. The upward movement of the piston ring 103 will lose contact with the magnetic rod 83.

[0051] Example 4

[0052] On the basis of Example 3, Figures 2 - 15As shown in the figure, it further includes a cleaning mechanism. The cleaning mechanism is arranged on the annular cylinder 104. The cleaning mechanism includes a mounting rod 112 and a cleaning knife 113. A wave groove 111 is formed on the outer wall of the annular cylinder 104. Two mounting rods 112 are slidably connected to the scraping knife 107. The iron ring 106 is located between the two mounting rods 112, and both of the two mounting rods 112 are slidably connected to the wave groove 111. Cleaning knives 113 are fixedly connected to the tops of the two mounting rods 112. The scraping knife 107 is located between the two cleaning knives 113, and the scraping knife 107 is in contact with both of the two cleaning knives 113.

[0053] When the scraping knife 107 rotates along the lower part of the outer wall of the small beer can 6, it will drive the two mounting rods 112 to rotate. The rotation of the mounting rods 112 will drive the cleaning knives 113 to rotate. While the two mounting rods 112 rotate, they will reciprocate up and down along the wave groove 111. The reciprocating up and down movement of the mounting rods 112 will drive the cleaning knives 113 to reciprocate up and down. The reciprocating up and down movement of the two cleaning knives 113 will scrape off the residual glue on the scraping knife 107, so that the scraping knife 107 can more quickly scrape off the excess special glue on the outer wall of the small beer can 6, thereby improving the efficiency of cleaning the residual glue; when the scraping knife 107 resets, it will drive the two mounting rods 112 to reset, and the reset of the mounting rods 112 will drive the cleaning knives 113 to reset.
