Description

Technical Field

[0001] The invention relates to the technical field of cylindrical box production, in particular to an automatic cylindrical box capping machine. Background Art

[0002] In the modern packaging industry, with the continuous improvement of product packaging efficiency and quality requirements, the application of automated packaging equipment is becoming more and more extensive. In the production process of cylindrical boxes, it is necessary to put a round cover on the cylindrical box to complete the final assembly, and then the cylindrical box with the round cover is subjected to subsequent processing.

[0003] In the prior art, automatic capping machines are widely used for assembling round caps on cylindrical boxes. The automatic capping machines are usually designed with a loading ramp for conveying the round caps from the storage area to the assembly position. However, due to the small overall size of the round caps and the force and speed of the sliding, the round caps are prone to bounce up and become misplaced when sliding to the assembly position, resulting in position deviation, which makes it impossible for the round caps to be accurately put on the cylindrical box to complete the capping process. This not only reduces the success rate of capping, but also increases the downtime of the equipment and the frequency of operator intervention, seriously affecting production efficiency.

[0004] Therefore, it is necessary to design an automatic cylindrical box capping machine that can accurately cap the round cap after buffering it in the assembly position to improve the success rate and production efficiency. Summary of the invention

When the clamping assembly is in operation, the clamping assembly can clamp and fix the cylindrical box.

[0033] See also Figure 5-Figure 7As shown, the feeding assembly includes a rotating shaft 15, a feeding wheel 151, a baffle 152, a torsion spring 1521 and a trigger assembly. The left rear side and the right front side of the top of the workbench 1 are both rotatably connected with the rotating shaft 15. The rotating shafts 15 on the left and right sides correspond to the feeding frame Ⅰ5 and the feeding frame Ⅱ6 respectively. The feeding wheel 151 is fixedly mounted on the rotating shaft 15. The outer side surface of the feeding wheel 151 is provided with grooves evenly spaced along the circumferential direction. The feeding wheel 151 rotatably penetrates the feeding frame Ⅰ5 and the feeding frame Ⅱ6. When the feeding wheel 151 rotates, the feeding wheel 151 can drive the cylindrical box and the round cover to rotate for transportation. The outer side surface of the feeding wheel 151 is rotatably connected with the baffle 15 evenly spaced along the circumferential direction. 2. The grooves of the baffle plate 152 and the feeding wheel 151 are arranged alternately. The baffle plate 152 can limit the round cover and the cylindrical box on the feeding wheel 151. A torsion spring 1521 is connected between the baffle plate 152 and the feeding wheel 151. A trigger assembly is arranged between the electric slide rail 7 and the rotating shaft 15. When the trigger assembly is operated, the trigger assembly can drive the rotating shaft 15 to rotate; the trigger assembly includes a rack 153 and a one-way gear 154. The ends of the rotating shafts 15 on the left and right sides close to the electric slide rail 7 are fixedly covered with the one-way gear 154. The moving parts of the electric slide rails 7 on the left and right sides are fixedly connected with racks 153, and the racks 153 are meshed with the one-way gear 154.

[0034] See also Figure 8 As shown, the clamping assembly includes a cross bar 16, a grid plate 161 and a driving assembly. The cross bar 16 is fixedly connected to the rear side of the top of the workbench 1, and the grid plate 161 is symmetrically slidably mounted on the cross bar 16. When the grid plate 161 moves and contacts the cylindrical box, the grid plate 161 can clamp and fix the cylindrical box. Guide grooves 162 are evenly spaced on the rear sides of the left and right sides of the material receiving frame 2. The grid plate 161 is located in the guide grooves 162. A driving assembly is provided on the workbench 1. When the driving assembly is in operation, the driving assembly can drive the grid plate 161 to move; the driving assembly includes a servo motor 163 and a bidirectional screw rod 164. The servo motor 163 is installed on the right rear side of the top of the workbench 1. The end of the output shaft of the servo motor 163 is fixedly connected to the bidirectional screw rod 164. The threads on the left and right sides of the bidirectional screw rod 164 are opposite, and the bidirectional screw rod 164 is threadedly connected to the lower part of the grid plates 161 on the left and right sides.

[0035] Initially, the connecting spring 12 is in a stretched state. First, a proper amount of round covers are placed in the feeding frame I5. The right-side limit block 8 limits the round covers, and the round covers contact with the grooves of the right feeding wheel 151. Then, a proper amount of cylindrical boxes are placed in the feeding frame II6. The left-side limit block 8 limits the cylindrical boxes, and the cylindrical boxes contact with the grooves of the left feeding wheel 151. The collecting container is placed on the rear side of the workbench 1, and then the electric slide rail 7 is started to drive the limit block 8 and the rack 153 to move upward. The rack 153 moves upward to drive the one-way gear 154 to idle. The limit block 8 moves upward to disengage from the innermost cylindrical box and round cover. The innermost cylindrical box and round cover fall downward and contact with the buffer strip 11. The buffer strip 11 buffers and limits the cylindrical box and round cover, so that the cylindrical box and round cover When the cylindrical box and the round cover are closer to the inner side of the material receiving frame 2, the baffle 152 limits the remaining cylindrical box and the round cover, and at the same time, the limit block 8 moves upward and drives the wedge frame 14 to move upward through the connecting frame 13. When the wedge frame 14 moves upward so that the inclined surface contacts the U-shaped rod 10, the wedge frame 14 stops limiting the U-shaped rod 10. Due to the action of the connecting spring 12, the buffer strip 11 moves outward and drives the U-shaped rod 10 to move outward, and the buffer strip 11 moves outward and stops limiting the cylindrical box and the round cover. The buffered cylindrical box and the round cover slide down into the material receiving frame 2. Since the cylindrical box and the round cover are closer to the inner side of the material receiving frame 2, the cylindrical box and the round cover are precisely located inside the material receiving frame 2. The electric slide rail 7 is closed, and the cylinder 3 is started. The telescopic rod of the cylinder 3 is extended to drive the push block 4 to move backward. The push block 4 moves backward and contacts the round cover, and the push block 4 drives the round cover to move backward, and the round cover moves backward and contacts the cylindrical box, and the round cover drives the cylindrical box to move backward and contacts the electric stopper 9. At this time, the servo motor 163 is started to drive the bidirectional screw rod 164 to rotate forward, and the bidirectional screw rod 164 rotates forward to drive the left and right side grid plates 161 to move in the guide groove 162 in the direction of approaching each other, and the left and right side grid plates 161 contact the cylindrical box, and the left and right side grid plates 161 clamp the cylindrical box to prevent the cylindrical box from moving left and right and affecting the assembly of the round cover, thereby improving the accuracy of the cover, and then the push block 4 continues to push the round cover backward, and the round cover moves backward and is sleeved on the fixed cylindrical box to complete the assembly, and then the cylinder 3 drives the push block 4 to move forward and reset, and at the same time the servo motor The machine 163 drives the bidirectional screw rod 164 to reverse, and the bidirectional screw rod 164 reverses to drive the left and right side grid plates 161 to move away from each other and reset, and the grid plate 161 is out of contact with the cylindrical box, and the electric block 9 moves to the right and stops to block the receiving frame 2, and the electric block 9 is out of contact with the cylindrical box, and then the cylinder 3 is started again to drive the push block 4 to move backward, and the push block 4 moves backward to push the covered cylindrical box out of the receiving frame 2, and the pushed cylindrical box falls into the collection container, and then the electric slide rail 7 is started again to drive the limit block 8 to move downward and reset, and the limit block 8 drives the wedge frame 14 to move downward and reset through the connecting frame 13. The reset of the wedge frame 14 drives the U-shaped rod 10 to move and reset, and the U-shaped rod 10 drives the buffer strip 11 to move and reset, and the connecting spring 12 is stretched.At the same time, the moving part of the electric slide rail 7 moves downward, driving the rack 153 to move downward, and the rack 153 moves downward to drive the one-way gear 154 to rotate. The rotation of the one-way gear 154 drives the rotating shaft 15 to rotate, and the rotating shaft 15 drives the feeding wheel 151 to rotate. The rotation of the feeding wheel 151 drives the baffle 152 to rotate. Due to the action of the torsion spring 1521, when the baffle 152 rotates and contacts the feeding frame Ⅰ5 and the feeding frame Ⅱ6, the baffle 152 can slide over the feeding frame Ⅰ5 and the feeding frame Ⅱ6, and the feeding wheel 151 rotates to drive the next cylindrical box and the round cover to rotate for transportation, so that the next cylindrical box and the round cover are contacted with the limit block 8 and are limited. When the rack 153 moves downward to reset, the rack 153 stops driving the one-way gear 154 to rotate, and the feeding wheel 151 stops rotating. According to the above operation, the round cover can be continuously put on the cylindrical box. When all the cylindrical boxes are covered, the covered cylindrical boxes can be processed later. In this way, the buffer strip 11 can buffer the cylindrical boxes and the round covers and then accurately slide them into the receiving frame 2 for assembly, so as to prevent the position deviation of the cylindrical boxes and the round covers from affecting the covering, thereby improving the success rate and production efficiency.

[0036] See also Fig. 9 and Fig.10 As shown, the automatic capping machine for cylindrical boxes also includes a positioning component installed between the feeding frame I5 and the feeding frame II6, the positioning component includes an elastic telescopic rod 17, a positioning plate 171, a movable plate 172 and a driving component, the front and rear sides of the feeding frame I5 and the feeding frame II6 are both symmetrically and slidably penetrated with the elastic telescopic rod 17, a positioning plate 171 is fixedly connected between the inner ends of the two elastic telescopic rods 17 on the same side, when the positioning plate 171 moves, the positioning plate 171 can realize the center positioning of the cylindrical box and the round cover, the outer ends of the two elastic telescopic rods 17 on the same side are fixedly connected with the movable plate 172, and a driving component is arranged on the workbench 1, when the driving component is in operation, the driving component can realize the movement of the movable plate 172; the driving component includes an installation Mounting plate 173, reciprocating screw rod 174 and double-axis motor 175, two mounting plates 173 are fixedly connected on the left rear side and the right front side of the workbench 1, and a reciprocating screw rod 174 is rotatably connected between the front and rear mounting plates 173. The reciprocating threads on the front and rear sides of the reciprocating screw rod 174 are opposite. The reciprocating screw rod 174 is threadedly connected to the lower part of the movable plate 172. When the reciprocating screw rod 174 rotates, the reciprocating screw rod 174 can drive the movable plate 172 to move back and forth. A double-axis motor 175 is installed on the left side of the top of the workbench 1, and the output shaft end on the rear side of the double-axis motor 175 is fixedly connected to the front end of the left reciprocating screw rod 174, and the output shaft on the front side of the double-axis motor 175 is connected to the front side of the right reciprocating screw rod 174 through a synchronous belt assembly.

[0037] When an appropriate amount of round covers are placed in the feeding frame I5 and an appropriate amount of cylindrical boxes are placed in the feeding frame II6, the double-axis motor 175 is started, and the double-axis motor 175 drives the left reciprocating screw 174 to rotate. The rotation of the left reciprocating screw 174 drives the two left movable plates 172 to move inward and outward at the same time. The left movable plate 172 drives the two left positioning plates 171 to move inward and outward at the same time through the left elastic telescopic rod 17. The left positioning plate 171 moves to contact the cylindrical box, and the left positioning plate 171 can position the cylindrical box in the center. At the same time, the double-axis motor 175 rotates through the synchronous belt assembly transmission belt The right reciprocating screw rod 174 is driven to rotate, and the right reciprocating screw rod 174 rotates to drive the two movable plates 172 on the right to move inside and outside at the same time. The right movable plate 172 drives the two positioning plates 171 on the right to move inside and outside at the same time through the right elastic telescopic rod 17. The right positioning plate 171 moves to contact the round cover. The right positioning plate 171 can center the round cover, and under the action of the elastic telescopic rod 17, the positioning plate 171 can adapt to round covers and cylindrical boxes of different lengths, thereby improving adaptability. The cylindrical boxes and round covers after centering are transported to the receiving frame 2 to complete assembly. When all the cylindrical boxes are covered with round covers, the double-axis motor 175 is turned off, the reciprocating screw rod 174 stops driving the movable plate 172 to move, and the positioning plate 171 also stops moving. In this way, the cylindrical boxes and round covers can be prevented from being offset during the conveying process to affect the subsequent cover processing, thereby ensuring that the cylindrical boxes are covered smoothly.

[0038] See also Fig.11 As shown, the automatic capping machine for cylindrical boxes also includes a material guiding frame 18 and a collecting frame 19. The material guiding frame 18 is fixedly connected to the middle part of the rear side of the workbench 1, and the feeding end of the material guiding frame 18 corresponds to the discharging end of the material receiving frame 2. The material guiding frame 18 can guide the cylindrical boxes after capping. A collecting frame 19 is placed at the lower part of the workbench 1, and the collecting frame 19 is located below the material guiding frame 18. The collecting frame 19 can collect and process the cylindrical boxes after capping.

[0039] When the covered cylindrical boxes are pushed out from the receiving frame 2, the cylindrical boxes are pushed into the guiding frame 18, and the cylindrical boxes in the guiding frame 18 slide into the collecting frame 19, which collects and processes the covered cylindrical boxes. When the collecting frame 19 is filled with an appropriate amount of cylindrical boxes, the collecting frame 19 is picked up to process the covered cylindrical boxes, and after all the cylindrical boxes are poured out, the collecting frame 19 is put back on the workbench 1. In this way, it is more convenient to collect and process the covered cylindrical boxes.
