Description

Technical Field

[0001] The invention relates to the field of packaging machinery, in particular to a beverage capping machine. Background Art

[0002] The capping machine is a machine that presses the cup lid onto the opening of the beverage cup to seal it. It is often used in beverage vending machines. The beverage vending machine mainly includes the cup dropping position, juice receiving position, cap dropping position, cap pressing position and cup taking position. After the beverage cup receives the beverage, it is switched to the cap dropping position through the position change mechanism, and the cup lid falls to the cup mouth, and then switched to the cap pressing position through the position change mechanism. After the cap pressing mechanism completes the pressing of the cup lid, it is switched to the cup taking position through the position change mechanism for the customer to take it away.

[0003] The existing Chinese patent with publication number CN109019472A discloses a capping machine, including a frame, a downward pressure cylinder assembly and a capping assembly; the downward pressure cylinder assembly is vertically installed in the frame, the upper end of the downward pressure cylinder assembly is fixedly connected to the frame, and the lower end of the downward pressure cylinder assembly is fixedly connected to the capping assembly, and the downward pressure cylinder assembly controls the upward and downward movement of the capping assembly; the capping assembly includes a pressing wheel sleeve and a pressing wheel shaft, the pressing wheel sleeve is in the shape of ∞, the pressing wheel sleeve fixed sleeve is arranged on the capping shaft, and the capping assembly composed of the pressing wheel sleeve and the capping shaft is still in the shape of ∞; the capping assembly in the shape of ∞ is pressed on the cup cover. During the capping process, the downward pressure cylinder assembly drives the capping assembly to press down, so that the cup cover can be pressed and fixed on the can mouth.

[0004] However, the above-mentioned capping machine has the following disadvantages: since the up and down movement of the capping assembly is controlled by the downward pressure cylinder assembly, the up and down movement stroke is controlled by the movement stroke of the cylinder piston rod. When it is necessary to cap cans of different heights, it is necessary to replace cylinders with different strokes, and it is impossible to directly and quickly adjust the up and down movement stroke of the capping assembly. Therefore, it is inconvenient and single to use, and the stroke cannot be flexibly adjusted. Summary of the invention

[0005] The object of the present invention is to provide a beverage capping device which is easy to use and can flexibly and diversely adjust the pressing stroke.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a beverage capping machine, comprising a frame and a shell covering the frame, a reduction motor is fixedly connected to the frame and a pressure block is movably arranged, a transmission assembly is arranged between the reduction motor and the pressure block, and the reduction motor drives the pressure block to move relative to the frame through the transmission assembly; a first micro switch and a push rod are arranged on the frame, the push rod is detachably connected to the frame, and a second micro switch is arranged on the pressure block, the first micro switch is in conflict with the pressure block, and the second micro switch is in conflict with the push rod; when the pressure block presses the cap, the second micro switch is in conflict with the push rod and stops driving the reduction motor, thereby limiting the downward stroke of the pressure block, and when the pressure block is retracted, the first micro switch is in conflict with the pressure block and stops driving the reduction motor, thereby limiting the upward stroke of the pressure block.

[0007] By adopting the above technical solution, when pressing the lid, the beverage cup with the cup cover is placed under the pressing block, the reduction motor is started and the pressing block is moved downward through the transmission component, and the cup cover is pressed on the cup mouth of the beverage cup. When the second micro switch conflicts with the push rod, the second micro switch controls the reduction motor to stop driving, thereby limiting the continued downward movement of the pressing block. When it is necessary to adjust the downward stroke of the pressing block, the push rod can be removed and replaced with a push rod of a different length; when the pressing block rises and resets, the output shaft of the reduction motor rotates in the opposite direction and drives the pressing block to move upward through the transmission component. When the top of the pressing block contacts the first micro switch, the first micro switch stops driving the reduction motor, thereby limiting the continued upward movement of the pressing block. In this way, it is more convenient to use, and the downward pressing stroke can be adjusted flexibly and diversely.

[0008] The present invention is further configured as follows: the top rod is detachably connected to the frame via threads.

[0009] By adopting the above technical solution, on the one hand, the push rod is connected to the frame through threads, which makes it easier to disassemble. On the other hand, the height of the push rod relative to the frame can be adjusted by simply rotating the push rod.

[0010] The present invention is further configured as follows: a mounting hole is provided on the frame, and the top rod is plugged and matched with the mounting hole.

[0011] By adopting the above technical solution, the ejector rod can be easily removed from the mounting hole and replaced with another ejector rod of appropriate length.

[0012] The present invention is further configured as follows: the transmission assembly comprises an output gear and a rack that are meshed with each other, the rack is arranged on the pressing block, the reduction motor drives the output gear to rotate, and the output gear drives the pressing block to move through the rack.

[0013] The present invention is further configured as follows: the reduction motor includes a housing, a drive motor and a reduction mechanism arranged in the housing, a drive gear is arranged on the output shaft of the drive motor, the drive gear is matched with the reduction mechanism for transmission, and the reduction mechanism includes a first-stage reduction gear set, a second-stage reduction gear set and a third-stage reduction gear set.

[0014] By adopting the above technical solution, the driving motor drives the driving gear to rotate, and the rotation of the driving gear drives the first-stage reduction gear set, the second-stage reduction gear set and the third-stage reduction gear set to transmit in sequence.

[0015] The present invention is further configured as follows: a first-stage reduction gear set includes a driven gear meshing with a driving gear, a second-stage reduction gear set includes a first connecting shaft and a first double gear, a second double gear, and a third double gear sleeved on the first connecting shaft; a third-stage reduction gear set includes a second connecting shaft and a fourth double gear, a fifth double gear, and a sixth double gear sleeved on the second connecting shaft, the first double gear is matched with the driven gear and the fourth double gear, the second double gear is matched with the fourth double gear and the fifth double gear, the third double gear is matched with the fifth double gear and the sixth double gear, and the sixth double gear is matched with the output gear.

[0016] By adopting the above technical solution, when the driven gear rotates, it drives the first double gear to rotate, the first double gear drives the fourth double gear to rotate, the fourth double gear drives the second double gear to rotate, the second double gear drives the fifth double gear to rotate, the fifth double gear drives the third double gear to rotate, the third double gear drives the sixth double gear to rotate, and the sixth double gear drives the output gear to rotate.

[0017] The present invention is further configured as follows: a U-shaped fixing frame for fixing the reduction motor is arranged on the frame, and both ends of the U-shaped fixing frame are fixedly connected to the frame by bolts.

[0018] By adopting the above technical solution, the U-shaped fixing frame can fix the reduction motor.

[0019] The present invention is further configured as follows: a pressing plate is movably arranged on the pressing block, a return spring is arranged between the pressing block and the pressing plate, the return spring makes the pressing plate in an inclined state relative to the pressing block, and when the cover is pressed, the pressing plate is pressed parallel to the pressing block.

[0020] By adopting the above technical scheme, when in the natural state, the pressure plate is away from the pressure block under the elastic force of the return spring, and the pressure plate is inclined relative to the pressure block; when pressing the lid, the pressure block drives the pressure plate to move downward, and the relative lowest point of the contact surface between the pressure plate and the cup lid contacts the cup lid, so that a part of the cup lid is fastened to the cup mouth. As the pressure block is pressed downward, the contact area between the cup lid and the pressure plate gradually increases, and the contact point extends circumferentially from the lowest contact point to both sides. At the same time, the pressure plate gradually tends to be horizontal. When the cup lid is completely pressed against the cup mouth, the pressure plate is parallel to the cup mouth and the pressure block, and the pressure plate is tightly attached to the pressure block. Compared with pressing the cup lid directly vertically, such inclined lid pressing is more convenient, and the cup lid is not easy to break and cause damage.

[0021] The present invention is further configured as follows: a semicircular protrusion is provided on the pressing plate, and an inner groove corresponding to the protrusion is provided on the pressing block.

[0022] By adopting the above technical solution, when the pressure plate is close to the pressure block, the protrusion is embedded in the inner groove, and the cooperation between the protrusion and the inner groove can play a certain limiting role, preventing the pressure plate from moving outward in the horizontal direction due to the elastic force of the return spring during the clamping process.

[0023] In summary, the present invention has the following beneficial effects:

[0024] 1. The first micro switch is in contact with the pressure block, and the second micro switch is in contact with the ejector rod to limit the upward and downward travel of the pressure block. The height of the ejector rod can be flexibly adjusted, which is more convenient to use. The downward travel can be flexibly and variously adjusted.

[0025] 2. The top rod is threadedly connected to the frame, making disassembly and height adjustment more convenient. BRIEF DESCRIPTION OF THE DRAWINGS

A U-shaped fixing frame 12 for fixing the reduction motor 2 is provided on the frame 1, and both ends of the U-shaped fixing frame 12 are fixedly connected to the frame 1 by bolts. During use, the pressure block 3 can move up and down in the vertical direction relative to the frame 1. The pressure block 3 includes a vertical flat plate 31 and a circular plate 32. The horizontal circular plate 32 is fixedly connected to the lower end of the vertical flat plate 31, and the circular plate 32 is adapted to the cup cover 41. During use, the beverage cup 4 is placed directly below the circular plate 32. The cup cover 41 is provided with an annular groove 411 that is interlocked with the cup mouth of the beverage cup 4 in the circumferential direction. When the pressure block 3 is pressed down, the cup cover 41 can be pressed tightly against the cup mouth of the beverage cup 4.

[0036] like Figure 2 and Figure 4As shown, the reduction motor 2 includes a housing 21, a driving motor 22 arranged in the housing 21, and a reduction mechanism. A driving gear 221 is arranged on the output shaft of the driving motor 22. The driving gear 221 is matched with the reduction mechanism in transmission. The reduction mechanism includes a primary reduction gear set, a secondary reduction gear set, and a third reduction gear set. The primary reduction gear set includes a driven gear 23 meshing with the driving gear 221. The secondary reduction gear set includes a first connecting shaft 24 and a first double gear 241, a second double gear 242, and a third double gear 243 sleeved on the first connecting shaft 24; the third reduction gear set includes a first double gear 241, a second double gear 242, and a third double gear 243 sleeved on the first connecting shaft 24. The reduction gear set includes a second connecting shaft 25 and a fourth double gear 251, a fifth double gear 252, and a sixth double gear 253 sleeved on the second connecting shaft 25, the first double gear 241 is in transmission cooperation with the driven gear 23 and the fourth double gear 251, the second double gear 242 is in transmission cooperation with the fourth double gear 251 and the fifth double gear 252, the third double gear 243 is in transmission cooperation with the fifth double gear 252 and the sixth double gear 253, the housing 21 is rotatably connected with the output gear 13, and the sixth double gear 253 is in transmission cooperation with the output gear 13. A rack 311 is arranged on the vertical plate 31 of the pressing block 3 in the vertical direction, and the rack 311 is meshed with the output gear 13.

[0037] When the driving motor 22 is driven, it drives the driving gear 221 to rotate, and the driving gear 221 drives the driven gear 23 to rotate. When the driven gear 23 rotates, it drives the first double gear 241 to rotate, the first double gear 241 drives the fourth double gear 251 to rotate, the fourth double gear 251 drives the second double gear 242 to rotate, the second double gear 242 drives the fifth double gear 252 to rotate, the fifth double gear 252 drives the third double gear 243 to rotate, the third double gear 243 drives the sixth double gear 253 to rotate, and the sixth double gear 253 drives the output gear 13 to rotate, so that the power can be transmitted to the output gear 13, and the output gear 13 cooperates with the rack 311 to drive the pressing block 3 to move up and down.

[0038] like Figure 3 As shown, a first micro switch 5 is provided at the upper end of the frame 1, and a push rod 6 is provided at the bottom of the frame 1. The push rod 6 is detachably connected to the frame 1 through threads. On the one hand, the push rod 6 is connected to the frame 1 through threads, which makes it more convenient to disassemble. On the other hand, the height of the push rod 6 relative to the frame 1 can be adjusted by simply rotating the push rod 6. In addition, a mounting hole can be opened on the frame 1, and the push rod 6 can be plugged into the mounting hole. In this way, the original push rod 6 can be removed from the mounting hole and replaced with another push rod 6 of appropriate length. A second micro switch 7 is provided at the top of the vertical plate 31. The first micro switch 5 is in contact with the top of the pressure block 3, and the second micro switch 7 is in contact with the push rod 6.

[0039] The basic working principle of the present invention is as follows: when pressing the lid, the beverage cup 4 with the cup cover 41 is placed under the pressing block 3, the reduction motor 2 is started and the pressing block 3 is moved downward as a whole through the transmission component, and the cup cover 41 is pressed on the cup mouth of the beverage cup 4. When the second micro switch 7 conflicts with the push rod 6, the second micro switch 7 controls the reduction motor 2 to stop driving, thereby limiting the pressing block 3 from continuing to move downward. When it is necessary to adjust the downward stroke of the pressing block 3, the push rod 6 can be rotated to adjust its height; when the pressing block 3 rises and resets, the output shaft of the reduction motor 2 rotates in the opposite direction and drives the pressing block 3 to move upward through the transmission component. When the top of the pressing block 3 contacts the first micro switch 5, the first micro switch 5 stops the reduction motor 2 from driving, thereby limiting the pressing block 3 from continuing to move upward. In this way, it has the effect of being more convenient to use, and the downward stroke can be adjusted flexibly and diversely.

[0040] Embodiment 2

[0041] A beverage capping device, such as Figure 5 and Figure 6 As shown, the difference between this embodiment and the first embodiment lies in that: a circular pressure plate 8 is movably provided on the lower end surface of the circular plate 32, and a plurality of return springs 9 are provided between the circular plate 32 and the pressure plate 8. The lengths of the plurality of return springs 9 first decrease and then increase along the circumferential direction, and the longest return spring 9 is arranged opposite to the shortest return spring 9. The plurality of return springs 9 make the pressure plate 8 in an inclined state relative to the circular plate 32, and a plurality of first mounting grooves 321 are provided on the lower end surface of the circular plate 32, and a plurality of second mounting grooves 82 are correspondingly provided on the upper end surface of the pressure plate 8, the upper end of the return spring 9 is welded in the first mounting groove 321, and the lower end of the return spring 9 is welded in the second mounting groove 82; a semicircular protrusion 81 is provided in the center of the upper end surface of the pressure plate 8, and an inner groove 33 corresponding to the protrusion 81 is provided in the center of the lower end surface of the circular plate 32.

[0042] When in the natural state, the pressing plate 8 is away from the circular plate 32 under the elastic force of the return spring 9, and the pressing plate 8 is inclined relative to the circular plate 32; when pressing the lid, the circular plate 32 drives the pressing plate 8 to move downward, and the relative lowest point of the contact surface between the pressing plate 8 and the cup cover 41 contacts the cup cover 41, so that the cup cover 41 is buckled on the cup mouth. As the circular plate 32 is pressed downward, the contact area between the cup cover 41 and the pressing plate 8 gradually increases, and the contact point extends circumferentially from the lowest contact point to both sides. At the same time, the pressing plate 8 gradually tends to be horizontal, and the return spring 9 is gradually compressed. When the cup cover 41 is completely pressed against the cup mouth, the pressing plate 8 is parallel to the cup mouth and the circular plate 32, and the pressing plate 8 is tightly attached to the circular plate 32. Compared with directly pressing the cup cover 41 vertically downward, such inclined pressing of the lid is more convenient, and the cup cover 41 is not easy to break and cause damage.

[0043] When the pressing plate 8 is close to the pressing block 3, the protrusion 81 is embedded in the inner groove 33. The cooperation between the protrusion 81 and the inner groove 33 can play a certain limiting role, preventing the pressing plate 8 from moving outward in the horizontal direction due to the elastic force of the return spring 9 during the clamping process.

[0044] The above description is only a preferred embodiment of the present invention, so all equivalent changes or modifications made according to the structure, characteristics and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
