This equipment can accurately rivet the pull tab at the designated position of the easy-open lid. Through specific riveting processes and mechanisms, appropriate pressure and acting forces are applied to firmly connect the pull tab and the easy-open lid together, ensuring that the pull tab will not fall off easily during subsequent use, and guaranteeing the convenience and safety of opening the beverage can.

[0003] The high-speed riveting and cutting combination machine for pull tabs of easy-open lids usually needs to go through steps such as material transportation, pull tab feeding, pull tab riveting, quality inspection, and finished product discharging to complete the riveting and cutting process of the pull tab of the easy-open lid. Among them, the finished products that pass the quality inspection are transported to the finished product collection area through the discharging device. The easy-open lids are put into the inside of the packing bag for packing, which can make them neatly stacked and placed, facilitating handling and loading / unloading, and being conducive to reasonable stacking in storage places such as warehouses, saving storage space.

[0043] The present invention has achieved the following beneficial effects:

[0044] (1) With the cooperation of the collection and regularization assembly provided in the present invention, the motor drives the rotating wheel to rotate. By using the inertia of the easy-open lid on the conveyor belt, it enters the specific gap area on the rotating wheel, and then with the restriction and guidance of the pushing plate, the easy-open lid is automatically converted from the horizontal transportation state to the vertical stacking state. The entire process does not require manual assistance. The automatic conversion and stacking method greatly reduces the manual operation links, reduces the labor cost, improves the production efficiency, ensures the consistency and regularity of the easy-open lid stacking, and with the cooperation of the pushing assembly, through the transmission of the rack plate and the gear, the rotating block and the inserting plate are driven to rotate, realizing the positioning and grasping of the easy-open lid. Then, the electric slide rail drives the slider to transfer the easy-open lid to the packing cover.

[0045] (2) The present invention uses the second electric push rod, the lifting plate, the connecting plate, the pneumatic rod, the first suction nozzle and the second suction nozzle to form a packing bag opening system. The air pressure device generates suction to open the bag mouth. At the same time, a limiting arc-shaped plate and a magnet are arranged on the top of the packing cover. The limiting arc-shaped plate restricts the horizontal movement of the easy-open lid, and the magnet uses the magnetic field to buffer and stabilize the easy-open lid, guiding it to accurately enter the packing bag. The automated opening system reduces the operation of manually opening the bag mouth, improves the packing efficiency, and the combined design of the limiting arc-shaped plate and the magnet ensures that the easy-open lid can accurately and smoothly enter the packing bag, avoiding the bagging mistakes caused by the deviation of the easy-open lid, and improving the bagging quality and efficiency.

[0046] (3) By setting the adjusting assembly in the present invention, by rotating the adjusting rod, the first adjusting block can move in the transverse adjusting seat, driving the roller to apply force to the conveyor belt, releasing the potential energy of the third spring rod, and pushing the second adjusting block to slide in the longitudinal adjusting seat, realizing the precise adjustment of the insertion distance of the inserting plate into the packing cover, and not affecting the force transmission to the inserting plate, enabling the equipment to adapt to the bagging requirements of different specifications of easy-open lids, greatly improving the versatility and flexibility of the equipment.

Detailed implementation manners

[0057] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0058] As Figures 1 - 3 shown, a high-speed riveting and cutting combination machine for pull tabs of easy-open lids includes a riveting and cutting frame 1, on the top of which there is a riveting and cutting machine 11, and a conveyor belt 12 is arranged on the riveting and cutting frame 1; a collection hood 13, which is symmetrically arranged on one side of the conveyor belt 12; a fixed seat 14 and a packing hood 15, the packing hood 15 is arranged on the top of the fixed seat 14, and a heating machine 16 is provided at one end of the packing hood 15 close to the collection hood 13; a collection and regularization assembly 2, which is arranged between the collection hood 13 and the conveyor belt 12 and is used to convert the easy-open lid from a horizontal state to a vertical state. The collection and regularization assembly 2 includes: a fixed disk 21, which is symmetrically installed at one end of the collection hood 13 close to the conveyor belt 12; a rotating wheel 22, which is rotatably connected between the two fixed disks 21; a pair of symmetric plates 23, which are arranged in an annular array on the side of the rotating wheel 22 corresponding to the conveyor belt 12. The fixed disk 21 at the rear end is equipped with a motor for driving the rotating wheel 22 to rotate; a pad concave plate 24, which is installed on the rotating wheel 22 and is located between the pair of symmetric plates 23. A gap area for pushing the easy-open lid away is formed between the symmetric plate 23 and the pad concave plate 24; a pushing plate 25, which is installed at one end of the collection hood 13 close to the conveyor belt 12 and is arranged on the top of the rotating wheel 22 in the gap area.

[0059] It should be noted that in the high-speed riveting and cutting combination machine for pull tabs of easy-open lids, first, the conveyor belt 12 transports the easy-open lids towards the direction of the collection hood 13. When the easy-open lids are transported to the end of the conveyor belt 12, due to the motor driving the rotating wheel 22 to rotate, the easy-open lids on the conveyor belt 12 enter the gap area between the symmetric plate 23 and the pad concave plate 24 corresponding to the rotating wheel 22 by inertia. As the rotating wheel 22 rotates, when the gap between the symmetric plate 23 and the pad concave plate 24 at the top of the rotating wheel 22 moves to the position of the pushing plate 25, under the limiting action of the pushing plate 25, since the pushing plate 25 is inclined, the easy-open lids will enter the interior of the collection hood 13 along the inclined surface. Due to the continuous transportation of the easy-open lids by the conveyor belt 12 and a certain speed, new easy-open lids will continuously enter the collection hood 13, enabling the easy-open lids to be stacked inside the collection hood 13. By setting the collection and regularization assembly 2, the automatic conversion of the easy-open lids from the horizontal transportation state to the vertical stacking state is realized, eliminating the need for manual bagging or adjusting the stacking state, reducing the manual operation links, lowering the labor intensity, and improving the production efficiency.

[0060] As Figure 2 、 Figure 4 and Figure 5As shown, the push assembly 211 is arranged between the symmetrical collection covers 13 and is used to push the easy-pull lid in a vertical state and collected neatly into the packaging cover 15. The push assembly 211 includes an electric slide rail 212, which is installed between the symmetrical collection covers 13; a slider 213, which is L-shaped, and its bottom is slidably connected to the top of the electric slide rail 212 and can move along the electric slide rail 212; a check counter 214, which is installed at the front and rear ends of the top of the vertical end of the slider 213; a first electric push rod 215, which is installed At the top of the horizontal end of the slider 213, there is a rack plate 216, which is connected to the top of the first electric push rod 215 and is connected to the slider 213 through a slide rail, and can slide relative to the slider 213 under the action of the first electric push rod 215; a gear 217, which is symmetrically arranged and rotatably connected to the right side of the vertical end of the slider 213 and meshes with the rack plate 216; a rotating block 218, which is installed on the side of the gear 217 away from the slider 213; an insert plate 219, which is arranged on the rotating block 218, and the bottom of the insert plate 219 is arranged with a pointed tip;

[0061] It should be noted that when the easy-open lids processed by the collection and arrangement component 2 are stacked vertically and enter the collection cover 13, the detection counter 214 starts to measure and count the number of easy-open lids in real time. When the detection counter 214 detects that the number of easy-open lids entering the collection cover 13 reaches a preset certain value, the system triggers the first electric push rod 215 to start working. After the first electric push rod 215 is started, it pushes the rack plate 216 connected to the top thereof to move upward. The upward movement of the rack plate 216 drives the gears 217 on both sides to rotate, thereby causing the insertion plate 218 set on the rotating block 218 to rotate. 219 also rotates accordingly, and the bottom of the insertion plate 219 is set with a pointed tip, which can be smoothly inserted between the counted easy-open lids during the rotation process to achieve positioning and grabbing of the easy-open lids. After the insertion plate 219 is inserted into the easy-open lids, the electric slide rail 212 starts to work, driving the L-shaped slider 213 slidably connected to its top to move along the electric slide rail 212. Since the insertion plate 219 has been inserted into the easy-open lids, the movement of the slider 213 will drive the insertion plate 219 and the inserted easy-open lids to move together, and finally push the easy-open lids into the packaging cover 15 to prepare for the subsequent packaging process;

[0062] The entire pushing process is highly automated, from counting and monitoring the number of pull-open lids, to rotating and inserting the insert plate 219, to transferring the pull-open lids, all of which are completed automatically by the equipment without manual intervention, greatly reducing manual labor intensity and improving production efficiency.

[0063] like Figure 4 , Figure 6 and Figure 7As shown in the figure, a groove 221 is provided above the middle of the rotating block 218. A rotating rod passing through the groove 221 is rotatably connected to the middle of the rotating block 218. An inclined passive plate 222 is installed at the top of the rotating rod in the groove 221. A slide rail frame 223 for providing stable movement for the reset seat 225 is installed at the left end of the rotating block 218. A first spring rod 224 that can be slidably connected to the reset seat 225 is installed inside the slide rail frame 223. The reset seat 225 is installed with a reset rod 226 that contacts the passive plate 222. On one side of the top of the fixed seat 14, a support frame 227 is installed. Symmetrical active plates 228 are installed on the support frame 227. The active plates 228 and the passive plates 222 are in the same horizontal position.

[0064] It should be noted that during the operation of the pushing component 211, when the electric slide rail 212 drives the slider 213 and the rotating block 218 installed on it to move, the insertion plate 219 is in the state of inserting into the easy-open lid, and drives the easy-open lid to move from the collection cover 13 towards the packing cover 15. At this time, the passive plate 222 on the rotating block 218 is in the normal position, and the reset seat 225 is in the initial state under the action of the first spring rod 224. There is a certain relative position relationship between the reset rod 226 and the passive plate 222. When the rotating block 218 moves close to the packing cover 15 along with the slider 213, the active plate 228 on the support frame 227 at the top of the fixed seat 14 will start to contact from the bottom of the inclined passive plate 222. As the rotating block 218 continues to move, the active plate 228 will generate an upward thrust on the passive plate 222. Under the thrust of the active plate 228, the passive plate 222 starts to reverse rotation. The rotation of the passive plate 222 will drive the rotation of the rotating rod, and the rotation of the rotating rod will further drive the associated insertion plate 219 to rotate along the direction of the packing cover 15. As the insertion plate 219 rotates, the insertion plate 219 gradually withdraws from between the easy-open lids, so that the easy-open lids originally fixed by the insertion plate 219 lose their restraint and completely enter the inside of the packing cover 15 from the inside of the collection cover 13, completing the unloading process of the easy-open lids. When the active plate 228 is separated from the passive plate 222, under the action of the first spring rod 224, the reset seat 225 slides with the reset rod 226, and the reset rod 226 pushes the passive plate 222 back to the initial position to prepare for the next operation.

[0065] This structure cleverly utilizes the movement of the rotating block 218 and the interaction between the active plate 228 and the passive plate 222 to realize the automatic rotation of the insertion plate 219 and the automatic unloading of the easy-open lids, without additional complex control devices and manual intervention, simplifies the production process, and improves the production efficiency.

[0066] As Figure 2 and Figure 7As shown in the figure, a support seat 321 is installed at one end of the top of the limit arc-shaped plate 237 close to the collection cover 13. A telescopic spring rod 322 is slidably connected to the top of the support seat 321. A pressing block is installed at the top of the telescopic spring rod 322. The heating machine 16 is arranged below the telescopic spring rod 322. The heating machine 16 has a semi-circular arc-shaped structure. An auxiliary plate 323 is installed between the support seat 321 and the collection cover 13.

[0067] It should be noted that when the easy-open lid enters the packing cover 15 through the collection and regulation assembly 2, the pusher assembly 211, etc., the operator can squeeze the telescopic spring rod 322 through the pressing block. After being squeezed, the telescopic spring rod 322 will contract and drive the heating machine 16 below to move downward. Since the heating machine 16 has a semi-circular arc-shaped structure, it can better fit the shape of the port of the packing bag. When the heating machine 16 descends to contact the port of the packing bag, the heating machine 16 is started to heat the port of the packing bag to achieve rapid sealing. After the easy-open lid passes through, no pressure is applied to the pressing block anymore. The telescopic spring rod 322 returns to the extended state under the action of its own elasticity, driving the heating machine 16 to rise back to the initial position to prepare for the next sealing operation.

[0068] As Figure 7 and Figure 8 As shown in the figure, a second electric push rod 231 is installed at the top of the fixed seat 14. A lifting plate 232 is installed at the moving end of the second electric push rod 231. Connecting plates 233 are installed at the front and rear ends of the lifting plate 232. Pneumatic rods 234 arranged in a linear array are installed at the bottom of the connecting plates 233. A first suction nozzle 235 is installed at the bottom of the pneumatic rods 234. A plurality of second suction nozzles 236 are installed inside the packing cover 15. The first suction nozzle 235 and the second suction nozzles 236 are connected by an external air pressure device.

[0069] It should be noted that, first, the packing bag is placed inside the packing cover 15, and the packing cover 15 provides a relatively closed and stable working space for the entire packing operation. When the packing operation is required, the second electric push rod 231 is started. After the second electric push rod 231 starts working, it will generate a downward thrust, driving the lifting plate 232 and the connecting plate 233 connected thereto to move downward synchronously. As the lifting plate 232 and the connecting plate 233 move downward, the pneumatic rod 234 and the first suction nozzle 235 installed under the connecting plate 233 gradually approach the packing bag, and finally contact with the upper surface of the packing bag. After the contact is in place, When the air pressure device is started and starts working, a certain air pressure difference will be generated, so that the second suction nozzle 236 and the first suction nozzle 235 will generate suction. Under the suction generated by the air pressure difference, the second suction nozzle 236 and the first suction nozzle 235 will tightly adhere to the two sides of the packaging bag, and the opening part of the packaging bag will be stretched open, thereby forming a channel for the easy-open lid to enter. From the positioning of the packaging bag to the formation of the opening and the bagging of the easy-open lid, the whole process is highly automated through the coordinated work of the second electric push rod 231, the air pressure device, etc., which greatly reduces manual participation, reduces labor intensity, and also improves production efficiency.

[0070] like Figure 8 As shown, an arc-shaped limiting arc plate 237 is installed on the top of the packaging cover 15, and a magnet 238 is symmetrically installed on the top of the limiting arc plate 237.

[0071] It should be noted that, due to the arc structure of the limiting arc plate 237, the horizontal movement of the easy-open cover is restricted, so that the easy-open cover can only move in the circular space surrounded by the packing cover 15 and the limiting arc plate 237, so as to prevent the easy-open cover from spreading randomly around and guide the easy-open cover to move in the direction of the packing bag. By setting the magnet 238, the material of the easy-open cover usually has a certain magnetic conductivity, and the magnetic field generated by the magnet 238 will produce a magnetic effect on the easy-open cover. On the one hand, this magnetic effect can play a certain buffering and stabilizing role in the movement of the easy-open cover, and prevent the easy-open cover from being moved during the movement. On the other hand, the easy-open lid can be kept in a relatively stable horizontal state to a certain extent to ensure that it can smoothly enter the packing bag without tilting or turning over. The circular space formed by the packing cover 15 and the limiting arc plate 237 and the limiting effect of the limiting arc plate 237 can effectively limit the easy-open lid to a specific area, so that it can move toward the packing bag more accurately, which greatly improves the accuracy of the easy-open lid entering the packing bag, reduces the bagging errors caused by the deviation of the easy-open lid, and ensures the quality and efficiency of bagging.

[0072] like Figure 7 and Figure 8As shown, the front and rear ends of the fixed seat 14 and the packing cover 15 are connected by a slide rail. A slide rail groove is provided inside the fixed seat 14. A second spring rod 239 passing through the slide rail groove is installed below the packing cover 15, and a foot pressure plate 2391 is installed at the lower end of the second spring rod 239.

[0073] It should be noted that in the initial state, the second spring rod 239 is in a natural state, and the packing cover 15 is held at a certain height position under the support of the second spring rod 239. When the packing bag is filled with pull tabs, the operator presses the foot pressure plate 2391 with the foot, causing the second spring rod 239 to compress and drive the packing cover 15 to move downward along the slide rail on the fixed seat 14. As the packing cover 15 moves downward, the packing bag also descends. When it descends to a certain position, the operator can conveniently take away the packing bag filled with pull tabs from the packing cover 15. When the operator releases the foot pressure plate 2391, the second spring rod 239 returns to its original state under the action of its own elasticity, extends upward and pushes the packing cover 15 to move upward along the slide rail, returning to the initial position, preparing for placing a new packing bag and filling it next time. With the design of the foot pressure plate 2391, the operator does not need to perform complex operations with hands, and only needs to gently press with the foot to achieve the descent of the packing cover 15, conveniently and quickly take away the filled packing bag, improving work efficiency.

[0074] As Figure 4 As shown, the adjusting assembly 3 is arranged on the rotating block 218 and is used to adjust the distance of the insertion plate 219. The adjusting assembly 3 includes a transverse adjusting seat 31: which is in the shape of a groove 221 and is fixedly connected to the rotating block 218, an adjusting rod 32: which is threadedly connected to the groove 221 inside the transverse adjusting seat 31, a first adjusting block 33: which is threadedly connected to the adjusting rod 32 and is slidably connected inside the transverse adjusting seat 31, a longitudinal adjusting seat 34: which is in the shape of a groove 221 and is installed on the top of the transverse adjusting seat 31, a third spring rod 35: which is installed inside the longitudinal adjusting seat 34, a second adjusting block 36: which is slidably connected to the third spring rod 35 and is slidably connected inside the longitudinal adjusting seat 34, a roller 37, which is installed at one end of the rotating rod and on one side of the first adjusting block 33 and the second adjusting block 36, and a conveyor belt 38, which is drivingly connected to each group of rollers 37.

[0075] It should be noted that when it is necessary to adjust the insertion distance of the insertion plate 219 into the inside of the packing cover 15, the adjusting rod 32 is rotated. The rotation of the adjusting rod 32 causes the first adjusting block 33 to move along the axial direction of the adjusting rod 32 within the lateral adjusting seat 31. When the first adjusting block 33 moves, the roller 37 connected to it will also move accordingly. The movement of the roller 37 exerts a force on the conveyor belt 38, and this force acts on the other roller 37 connected to the conveyor belt 38, and this roller 37 is connected to the second adjusting block 36. At this time, the elastic potential energy of the third spring rod 35 is released, and the elastic force of the third spring rod 35 pushes the second adjusting block 36 to slide on the longitudinal adjusting seat 34. During the entire adjustment process, although the first adjusting block 33 and the second adjusting block 36 move, the roller 37 always remains rotatably connected to the rotating rod, the first adjusting block 33 and the second adjusting block 36. The rotation of the rotating rod can transmit power to the insertion plate 219 through the roller 37, and the conveyor belt 38 always maintains a driving connection with the roller 37 during the adjustment process. Therefore, it will not affect the power transmission from the roller 37 on the rotating rod to the insertion plate 219, thus ensuring that the insertion plate 219 can work normally and realizing the adjustment of its insertion distance at the same time. By adjusting the adjusting rod 32, the moving distance of the first adjusting block 33 can be accurately controlled, and then through a series of linkage effects, the accurate adjustment of the insertion distance of the insertion plate 219 into the inside of the packing cover 15 can be realized. This enables the equipment to adapt to the bagging requirements of different specifications of easy-open lids, improving the versatility and flexibility of the equipment.

[0076] The working principle of the present invention is as follows. For a high-speed riveting and cutting combination machine for pull tabs of easy-open lids, during use, the conveyor belt 12 sends the easy-open lids to the end. The motor drives the rotating wheel 22 to rotate. The easy-open lids enter the gap between the symmetric plate 23 and the pad concave plate 24 on the rotating wheel 22 by inertia. As the rotating wheel 22 rotates, the gap moves to the position of the pushing plate 25. The inclined pushing plate 25 causes the easy-open lids to enter the collection cover 13 and stack up, realizing the conversion from the horizontal state to the vertical state. The inspection counter 214 monitors the number of easy-open lids in the collection cover 13. When the preset value is reached, the first electric push rod 215 is activated, driving the rack plate 216 to move upward, causing the gear 217 to rotate. The rotating block 218 and the insertion plate 219 rotate, and the tip inserts between the easy-open lids. Subsequently, the electric slide rail 212 drives the slider 213 to push the easy-open lids to the packing cover 15. When the rotating block 218 approaches the packing cover 15 along with the slider 213, the active plate 228 contacts the passive plate 222 and pushes it to reverse rotation, driving the rotating rod and the insertion plate 219 to rotate. The insertion plate 219 is withdrawn, and the easy-open lids fall into the packing cover 15. After the active plate 228 is separated from the passive plate 222, the first spring rod 224 resets the passive plate 222. The packing bag is placed in the packing cover 15. The second electric push rod 231 is activated, driving the lifting plate 232, the connecting plate 233, the pneumatic rod 234, and the first suction nozzle 235 to descend and contact the packing bag. The pneumatic device is activated, and the first suction nozzle 235 and the second suction nozzle 236 generate suction to expand the bag opening. The easy-open lids enter. The limiting arc-shaped plate 237 restricts the horizontal movement of the easy-open lids. The magnet 238 generates magnetic force to buffer and stabilize the easy-open lids, enabling them to smoothly and accurately enter the packing bag. After the packing bag is full, the operator steps on the foot pressure plate 2391, and the second spring rod 239 is compressed. The packing cover 15 descends. The operator takes away the packing bag and releases the foot pressure plate 2391. The second spring rod 239 resets, and the packing cover 15 rises. The adjusting rod 32 is rotated, and the first adjusting block 33 moves in the horizontal adjusting seat 31, driving the roller 37 to apply force to the conveyor belt 38, releasing the potential energy of the third spring rod 35, and pushing the second adjusting block 36 to slide in the longitudinal adjusting seat 34. During the adjustment, the middle roller 37 remains connected to the rotating rod, the first adjusting block 33, and the second adjusting block 36, without affecting the transmission of force to the insertion plate 219, realizing precise adjustment of the insertion distance.
