Description

Technical Field

[0001] The invention belongs to the technical field of nut packaging, in particular to an automatic packaging production line for high-lock nuts. Background Art

[0002] High-strength self-locking nuts are a category of self-locking nuts. They have high strength and strong reliability. They are mainly based on the introduction of European technology and are used in road construction machinery, mining machinery, vibration machinery and equipment, etc. High-locking nuts are key components in mechanical assembly, and their packaging process must take into account damage prevention, sealing and efficiency. Traditional packaging methods rely on manual operations.

[0003] However, manual bagging and sealing by workers can easily lead to slow packaging speed, and human operational errors may cause nuts to be missed or packaging to be damaged. The existing automated equipment does not fully solidify the sealing end after heat sealing, causing high-lock nuts to impact the sealing part when loaded, causing the risk of rupture. In addition, the nuts cannot be quickly and effectively sorted during loading and transportation, which will cause changes in the accuracy of subsequent segmented loading.

[0004] By stirring the materials in the collecting box, the threads are prevented from accumulating at the discharge port and causing material blockage, thereby ensuring the nut feeding rate. By strengthening the firmness of the heat-sealed ends, the packaging bags are prevented from breaking when the nuts are packaged. The nuts are transported in sections when they are fed, so that the accuracy of nut packaging can be effectively controlled in the subsequent packaging process. Summary of the invention

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention cooperates with structures such as a feeding box, a feeding baffle plate, and a torsion spring so that the device can, after the nut enters the feeding box through the vibration generated by the start-up of the vibration motor, fall into the top of the feeding baffle plate. At this time, the restoring force provided to the feeding baffle plate by the torsion spring can make the feeding baffle plate rotate only when the limit value of its own restoring force is reached, so that the nuts inside the feeding box fall into the collecting trough and are packaged. Furthermore, the user can start the third servo motor and open the feeding baffle plate by himself according to the speed of the third servo motor to complete the packaging of nuts of different quantities and specifications required by different customers. Furthermore, by energizing the electromagnet, the electromagnet and the bottom end of the feeding box can be adsorbed on each other, and then the magnetic force is used to control the quantitative blanking of the nuts, so that the device can use a variety of methods to achieve the quantitative effect of dropping nuts, thereby ensuring the accuracy of the nut blanking and packaging of the nuts by the device, thereby achieving the purpose of facilitating the device to accurately package and blank the nuts.

[0020] The present invention arranges a packaging table, a collecting trough, a card slot and other structures in coordination, so that the device can fix the top end of the packaging bag on the card slot and make it hang naturally, and start the first cylinder and the second cylinder to extrude the first heat sealing plate and the second heat sealing plate. When the first heat sealing plate and the second heat sealing plate are in contact, they start to generate heat to heat-seal the packaging bag. Due to the extrusion, the first heat sealing plate and the second heat sealing plate will be in closer contact, and the contact surface is large enough, so that the sealing area becomes larger, thereby avoiding the phenomenon that the packaging bag is broken when the nuts are packaged, so as to achieve the purpose of ensuring the strength of the connection of the packaging bag when the device is used to package the nuts.

[0021] The present invention arranges the coordination of the first servo motor, gears, transmission ring and other structures so that when the user places a large number of nuts in the storage box, the nuts fall into the top end of the first conveyor belt through the discharge port and are accumulated when the first conveyor belt is not started. At this time, starting the first conveyor belt to transport the nuts will cause the nuts to accumulate at the discharge port and cannot be discharged. By starting the first servo motor to drive the gear to rotate, the shape of the gear drives the transmission ring and the stirring rod to rotate, so that the stirring rod can stir the nuts inside the storage box when moving, thereby helping the device to drop the nuts and improving the effect of packaging the nuts.

Due to the extrusion, the first heat sealing plate 805 and the second heat sealing plate 807 will be in closer contact, and the contact surface is large enough, so that the sealing area becomes larger.

[0040] like Figures 1 to 8 As shown, the feeding mechanism 2 includes a first servo motor 201, a gear 202 and a transmission ring 203. The first servo motor 201 is fixed at the top of the storage box 1. The gear 202 is fixed to the outside of the first servo motor 201.

[0042] The working principle and use process of the present invention are as follows: when a large number of nuts are placed inside the storage box 1, the nuts fall into the top of the first conveyor belt 3 through the discharge port, and are accumulated when the first conveyor belt 3 is not started, and the second servo motor 404 is started to drive the second connecting rod 403 to rotate and then drive the belt 405 to move, and synchronously drive the first connecting rod 402 to rotate. When the belt 405 moves, the dividing plate 406 will move upward following the movement of the belt 405, and then the nuts transported by the first conveyor belt 3 will fall between the dividing plates 406 of each group, and be separated and transported to the upper material tray 5 for separation. When the nuts enter the interior of the loading tray 5, the vibration motor 6 is started to vibrate the loading tray 5, and then the nuts are evenly transported to each group of the discharge boxes 701 along the arc groove, and after the device packs the nuts, the second conveyor belt 9 is started to transport and collect the packaged nuts. The user can start the third servo motor 704 and The baffle plate 702 is opened automatically by the rotation speed of the third servo motor 704 to complete the packaging of nuts of different quantities and specifications required by different customers.

When the first heat sealing plate 805 and the second heat sealing plate 807 are in contact, they start to generate heat to heat-seal the packaging bag. Due to the extrusion, the first heat sealing plate 805 and the second heat sealing plate 807 will be in closer contact, and the contact surface is large enough to increase the sealing area. After heat-sealing packaging, the packaged nuts fall to the top of the second conveyor belt 9 for further transportation.
