Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically a new type of packaging machine. Background Technology

[0002] The efficiency and quality of friction welding in strapping machines largely depend on the smooth operation of the transmission system. In existing friction welding knife transmission schemes, the cam-link mechanism is widely used. It transmits power through the rolling contact between the drive boss and the roller, and the hinged transmission between the connecting rod and the swing arm. However, in actual use, this type of mechanism suffers from significant noise interference and insufficient operational stability: Firstly, when the crests and troughs of the drive boss alternately contact the roller, a periodic impact force is generated. Combined with the hinge gap between the connecting rod and the swing arm, this easily leads to vibration during operation, resulting in noticeable noise. Under high-speed welding conditions, the noise pollution is even more severe, adversely affecting the working environment. Secondly, the clearance between multiple hinge points in the transmission chain gradually accumulates, reducing the accuracy of the friction welding knife's reciprocating motion and causing slight deviations or wobbling. This not only affects the consistency of the strapping tape welding quality but also further exacerbates component wear due to unstable movement, affecting the long-term stable operation of the equipment.

[0003] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to this case. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a novel packaging machine. To achieve the above objectives, this utility model provides the following technical solution: A novel packaging machine includes a frame, with a welding assembly inside the frame and a material guiding assembly above the welding assembly. The welding assembly includes a cylinder, a mounting frame, a motor, a rotating shaft, an adapter, and a friction head. The motor is fixedly connected to the upper end of the mounting frame, and the rotating shaft is rotatably connected to the mounting frame. The motor drives the rotating shaft to rotate. The friction head is slidably connected to the lower end of the mounting frame, and the upper end of the friction head is fixedly connected to the lower end of the adapter. The lower end of the rotating shaft has an eccentric frustum, and the upper end of the adapter has a drive groove that mates with the eccentric frustum. The cylinder is connected to the upper end of the mounting frame and drives the mounting frame to move up and down. The material guiding assembly includes a guide plate and a welding block. The guide plate is fixedly connected to the frame, and the lower surface of the guide plate has a guide groove. The welding block is fixedly connected to the guide groove.

[0005] Furthermore, a first bearing is fitted on the eccentric circular platform, and the drive groove includes a drive part and clearance parts on both sides of the drive part. The drive part and the first bearing cooperate with each other, and the clearance parts provide clearance when the first bearing swings.

[0006] Furthermore, the upper end of the friction head is provided with a slider, the lower end of the mounting bracket is provided with a sliding groove that slides with the slider, the two side walls of the slider are provided with a first guide groove, the side wall of the groove is provided with a second guide groove corresponding to the side of the first guide groove, and the first guide groove and the second guide groove are provided with balls.

[0007] Furthermore, the lower end of the adapter is provided with a connecting groove, and the upper end of the slider is provided with a connecting boss, which is embedded in the connecting groove for engagement.

[0008] Furthermore, the top wall of the drive groove is provided with a countersunk hole communicating with the connecting groove, and the connecting boss is provided with a threaded hole communicating with the countersunk hole.

[0009] Furthermore, the mounting frame includes an upper frame, a lower frame, and a cover plate connected vertically.

[0010] Furthermore, the guide belt groove is provided with a positioning groove, the welding block is embedded in the positioning groove, and the welding block is locked to the guide belt plate by screws.

[0011] This utility model provides a novel packaging machine. It has the following beneficial effects: 1. In this utility model, the transmission path of the friction head is significantly shortened, the overall structure is simpler and more compact, the inertia of the transmission system is significantly reduced, and the starting and running load of the motor is effectively reduced. Furthermore, the motor uses rolling friction with the adapter through an eccentric frustum and a first bearing, replacing the sliding friction mode with multiple hinge points in the traditional solution. This results in lower frictional resistance and more balanced force distribution, avoiding wear and jamming problems caused by alternating impacts from multiple components. The service life of the core transmission components is significantly extended, and the frequency of equipment maintenance and overall costs are significantly reduced.

[0012] 2. This utility model ensures functional integrity while also taking into account structural compactness and ease of maintenance. The material guiding component and the welding component are integrated and assembled in the frame. The mounting frame adopts a layered design, and the components are arranged in an orderly manner, significantly reducing the overall space occupied compared to traditional solutions, making it suitable for more confined workstation scenarios. The adapter and slider form a quick-release structure, and the welding block adopts a detachable screw locking design. During disassembly and assembly, there is no need to disassemble the entire mechanism; only a single screw needs to be operated to complete the replacement and maintenance of the components, greatly reducing maintenance difficulty and downtime costs.

[0013] 3. The short transmission path in this utility model reduces the multi-stage attenuation in the energy transmission process, and the motor output power can be directly applied to the friction head, which greatly improves the effective power utilization rate. It can achieve the designed welding effect without relying on a high-power motor, thus reducing the equipment manufacturing cost. Furthermore, the friction coefficient of the first bearing, ball bearings and other rolling friction components is much lower than that of traditional sliding friction, which further reduces energy loss. Under the premise of ensuring welding efficiency and quality, energy saving and consumption reduction are achieved during the operation phase. Attached Figure Description

Detailed Implementation

[0016] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please see the appendix Figure 1 - Appendix Figure 8This utility model provides a novel packaging machine, including a frame 6. A welding assembly is located inside the frame 6, and a material guiding assembly is located above the welding assembly. The welding assembly includes a cylinder 11, a mounting frame 2, a motor 12, a rotating shaft 13, an adapter 3, and a friction pressure head 4. The motor 12 is fixedly connected to the upper end of the mounting frame 2, and the rotating shaft 13 is rotatably connected to the mounting frame 2. The motor 12 drives the rotating shaft 13 to rotate. The friction pressure head 4 is slidably connected to the lower end of the mounting frame 2, and the upper end of the friction pressure head 4 is connected to the adapter. The lower end of the adapter 3 is fixedly connected, and the lower end of the rotating shaft 13 is provided with an eccentric frustum 131. The upper end of the adapter 3 is provided with a drive groove 31 that cooperates with the eccentric frustum 131. The cylinder 11 is connected to the upper end of the mounting frame 2 and drives the mounting frame 2 to move up and down. The material guiding assembly includes a guide plate 51 and a welding block 52. The guide plate 51 is fixedly connected to the frame 6. The lower surface of the guide plate 51 is provided with a guide groove. The welding block 52 is fixedly connected to the guide groove and is correspondingly positioned above the friction pressure head 4. With the above structure, the cable tie in the frame 6 is conveyed to the welding assembly and the material guiding assembly through the feeding mechanism and enters the guide groove. Then, the cylinder 11 drives the mounting frame 2 to rise, driving the friction pressure head 4 to approach the welding block 52. Then, the motor 12 drives the rotating shaft 13 to rotate and transmits the power through the adapter 3, driving the friction pressure head 4 to move back and forth repeatedly on the mounting frame 2, so that the friction pressure head 4 and the welding block 52 weld the cable tie.

[0018] In this embodiment, a first bearing 132 is fitted onto the eccentric frustum 131. The drive groove 31 includes a drive part 311 and clearance parts 312 on both sides of the drive part 311. The drive part 311 and the first bearing 132 cooperate with each other, and the clearance parts 312 provide clearance for the first bearing 132 when it swings. Specifically, the distance between the drive parts 311 is D1, and the size of D1 is equal to the diameter of the bearing. The distance between the clearance parts 312 is D2, and the size of D2 is larger than the diameter of the bearing, so that the groove of the drive groove 31 is racetrack shaped. In this way, when the first bearing 132 swings, it will only contact the side wall of the drive part 311, and will not contact the side wall of the clearance part 312, thus driving the friction head 4 to move back and forth.

[0019] In this embodiment, the upper end of the friction head 4 is provided with a slider 41, and the lower end of the mounting bracket 2 is provided with a groove that slides with the slider 41. The sidewalls of the slider 41 are provided with first guide grooves 411, which can be one or more. The sidewalls of the grooves are provided with second guide grooves 21 corresponding to the sides of the first guide grooves 411. Ball bearings 211 are provided within the first and second guide grooves 411. With this structure, the ball bearings 211 cooperate with the first and second guide grooves 411 to form a linear guide rail structure, locking the friction head 4 onto the mounting bracket 2 and guiding the translation of the friction head 4, further improving the stability of the friction head 4 during movement.

[0020] In this embodiment, the lower end of the adapter 3 is provided with a connecting groove 32, and the upper end of the slider 41 is provided with a connecting boss 412, which is embedded in the connecting groove 32. The top wall of the drive groove 31 is provided with a countersunk hole communicating with the connecting groove 32, and the connecting boss 412 is provided with a threaded hole communicating with the countersunk hole. By inserting a screw into the countersunk hole and threading the lower end of the screw into the threaded hole, the adapter 3 and the connecting boss 412 are fixedly connected together. The structure is simple and the disassembly and assembly are more convenient.

[0021] In this embodiment, the mounting frame 2 includes an upper frame 22, a lower frame 23, and a cover plate 24 connected vertically. The motor 12 is fixedly installed inside the lower frame 23. The cover plate 24 is connected to the piston rod of the cylinder 11. The upper frame 22 has mounting holes 25, and several second bearings 26 are provided in the mounting holes 25. The second bearings 26 are sleeved on the rotating shaft 13. In addition, the lower end of the upper frame 22 is provided with a cutter 27 fixedly connected to it. When the cutter 27 rises, it can cut the cable ties.

[0022] In this embodiment, a positioning groove 511 is provided in the guide belt groove, and the welding block 52 is embedded in the positioning groove 511. The welding block 52 is fixed to the guide belt plate 51 by screws. This makes the installation of the welding block 52 more secure and the disassembly and assembly more convenient.

[0023] The working principle of this utility model is as follows: The cable ties in the frame 6 are conveyed to the welding assembly and the guide assembly through the feeding mechanism and enter the guide groove. Then, the cylinder 11 drives the mounting frame 2 to rise, so that the friction pressure head 4 approaches the welding block 52. Then, the motor 12 drives the rotating shaft 13 to rotate. When the rotating shaft 13 rotates, it drives the first bearing 132 to swing in the drive groove 31 through the eccentric frustum 131. When the first bearing 132 swings, it is in contact with the drive part 311 in the drive groove 31, thereby driving the friction pressure head 4 to move back and forth repeatedly at the lower end of the mounting frame 2 to weld the cable ties.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
