Description

TECHNICAL FIELD

[0001] The utility model relates to Christmas tree production equipment technical field, especially a Christmas tree branch binding machine. BACKGROUND

[0002] With the vigorous development of holiday culture, the market demand of artificial Christmas trees is increasing, and the manufacturing process is increasingly pursuing automation and refinement. The existing Christmas tree automatic tree head branch binding machine mainly undertakes the heavy task of accurately binding the artificial Christmas tree branches on the rod material, and the high-temperature meltable yarn is often used to complete the basic binding process. In order to further improve the decoration effect, many artificial Christmas trees also need to be additionally wrapped with rattan, which can cleverly shield the yarn and create a more beautiful visual experience.

[0003] In the application of automation technology, such as the utility model patent authorized announcement number CN213909646U described a kind of Christmas tree branch binding semi-automatic tree head machine, it has already had key components such as winding binding device, lock line fuse line device and branch clamping device. These components have many ingenious designs: the combination of winding pipe and reel increases the radius of yarn rotation, optimizes the binding range while reducing its weight; The linkage of annular mounting plate and constraint core reduces the torsion and tension, and improves the uniformity of binding; The fuse clamp integrates with the temperature sensor and the fuse, to realize automatic fusion, and the special structure of the line hook and the clamping block strengthens the stability of the thread end; There is also a parallel claw hand air cylinder, which can automatically wrap rattan and bring low-cost and high-efficiency production advantages.

[0004] However, the existing technology still has significant defects. The winding binding device lacks flexibility and is difficult to adapt to different sizes of rod materials, which greatly limits its application scenarios. Moreover, when different sizes of rod materials are used for processing, the fuse assembly also needs to be adjusted for the cooperation between the rod materials. When the radial size of the rod material is too small, the arc surface structure does not contact or does not contact tightly with the rod material, which will cause the yarn to be unable to effectively fuse on the rod material. When the radial size of the rod material is too large, the arc surface structure will be stressed too much when it contacts with the rod material, which will affect the gripping force of the parallel claw hand air cylinder and easily cause damage to the parallel claw hand air cylinder. In addition, the hot fuse clamp needs to be preheated, and the hot fuse clamp needs to be heated all the time to ensure the working efficiency, which will increase the power consumption. Therefore, it is necessary to propose an improved technical scheme to solve the above problems. UTILITY MODEL CONTENTS

Detailed Implementation

[0035] The technical solutions in the embodiments of this utility model will be clearly and completely described below. 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.

[0036] Please see Figures 1-10 In this embodiment of the utility model, a Christmas tree tying machine is used to tie branches and vines to the surface of tree branches by winding yarn. The machine includes a body 10, on which are mounted a tree branch butt winding machine 20, an ultrasonic wire bonding machine 30, a tree branch transfer and rotation machine 40, a yarn orientation supply component 11, and a vine orientation supply component 12; wherein:

[0037] The bar stock winding unit 20 includes a large-diameter winding tube 21 rotatably connected to the machine body 10, a first power mechanism 22 installed on the machine body 10 for driving the large-diameter winding tube 21 to rotate, and a bar stock adapter 23 detachably installed at the front end of the large-diameter winding tube 21; a yarn orientation supply component 11 is connected to the rear end of the large-diameter winding tube 21, and a yarn channel 25 is provided on the outside of the large-diameter winding tube 21 so that the yarn provided by the yarn orientation supply component 11 can pass through the yarn channel 25 to the front end of the large-diameter winding tube 21; and a rattan orientation supply component 12 is connected to a position on one side in front of the large-diameter winding tube 21.

[0038] The ultrasonic wire bonding unit 30 includes a support block 31 for laterally clamping the bar stock that is connected to the large-diameter winding tube 21, a wire clamping cylinder 32 for clamping the yarn end, an ultrasonic welder 33 for ultrasonically welding the yarn wound on the surface of the bar stock, and a power transfer module 34 installed on the machine body 10. The power transfer module 34 is used to simultaneously drive the support block 31, the wire clamping cylinder 32 and the ultrasonic welder 33 to connect to the bar stock.

[0039] The bar stock transfer rotary unit 40 includes a bar stock conveying platform 41 mounted on the body 10, a bar stock abutting cylinder 42 mounted on the bar stock conveying platform 41 for supporting and abutting the bar stock that is docked at the large-diameter winding tube 21, a linear conveying module 43 mounted on the bar stock conveying platform 41, a fixed frame 44 powered by the linear conveying module 43, a rigid air pipe 45 rotatably connected to the fixed frame 44 and axially corresponding to the large-diameter winding tube 21, a second power mechanism 46 fixedly mounted on the fixed frame 44 for driving the rigid air pipe 45 to rotate, a bar stock end gripping cylinder 47 fixedly connected to one end of the rigid air pipe 45 and connected to the air passage of the rigid air pipe 45, and a high-speed rotating air pipe connector 48 connected to the other end of the rigid air pipe 45.

[0040] Its working principle is as follows:

[0041] 1) Connection of yarn and rattan: The yarn is fed into the Christmas tree head binding machine along the yarn orientation supply 11, and then passed through the yarn channel 25 to the front end of the large diameter winding tube 21. The rattan is fed into the Christmas tree head binding machine along the rattan orientation supply 12. Finally, the yarn and rattan are clamped on the clamping cylinder 32.

[0042] 2) Bar Stock Connection and Preparation: First, the bar stock and the large-diameter winding tube 21 are connected using the bar stock adapter 23. At this time, the linear conveyor module 43 moves the bar stock end gripping cylinder 47 towards the bar stock, and the bar stock end gripping cylinder 47 tightly clamps one end of the bar stock. After the worker places the Christmas branch on the material plate, the linear conveyor module 43 then inserts a small section of the bar stock into the large-diameter winding tube 21, allowing the base of the Christmas branch to also enter the winding tube, preparing for subsequent winding.

[0043] 3) Yarn winding and welding: During the yarn winding stage, the power transfer module 34 pushes the support block 31, the yarn clamping cylinder 32, and the ultrasonic welder 33 closer to the bar stock. The yarn clamping cylinder 32 clamps the yarn and the vine, and then the first power mechanism 22 drives the large-diameter winding tube 21 to rotate. Since the yarn is arranged along the yarn channel 25 on the outside of the large-diameter winding tube 21, and the bar stock is fixed by the bar stock end gripping cylinder 47, the yarn will start from the yarn clamping cylinder 32 and wind along the bar stock and the Christmas branch. After the yarn is wound, the support block 31 and the bar stock resisting cylinder 42 resist the bar stock. At the same time, the ultrasonic welder 33 is turned on, using ultrasound to weld the wound yarn, firmly binding the Christmas branch to the bar stock.

[0044] 4) Rod Rotation and Full Winding: After initial binding, the second power mechanism 46 drives the rigid air tube 45 to rotate, which in turn causes the rod clamped by the rod end gripping cylinder 47 to rotate, and the yarn and rattan are further wound around the rod. Subsequently, the linear conveyor module 43 moves the rod a short distance forward to the large-diameter winding tube 21, and repeats the above winding and welding operations at the new position of the rod. Moreover, the linear conveyor module 43 can also move the rod back and forth to expand the area of ​​winding and binding.

[0045] 5) Rattan supply: Throughout the process, the rattan directional supply unit 12 continuously supplies rattan to the large-diameter winding tube 21, enabling it to complete the decorative winding of the rod material together with the yarn.

[0046] In the above technical solution, the front end of the large-diameter winding tube 21 is equipped with a detachable rod adapter 23, which can be adapted to rods of different sizes, overcoming the problem that traditional winding and binding devices are difficult to adapt to various iron rod sizes, thus broadening the applicability of the equipment. Furthermore, the use of ultrasonic welding technology, compared to traditional manual knotting and fusion methods, can more firmly bind the Christmas branches to the rods, greatly reducing the risk of branches falling off during product use and ensuring product quality. By using the support block 31 and the rod-holding cylinder 42 to hold the rods, the rods can be properly gripped during the yarn fusion stage, and the device can adapt to different rod sizes, ensuring that the ultrasonic welder 33 can flexibly adapt to rods of different sizes during the yarn welding process.

[0047] The bar material transfer and rotation unit 40 enables the linear conveyor module 43 to drive the bar material to move back and forth. In conjunction with the rotation of the bar material, the area of ​​winding and binding can be increased, making the winding of yarn and vines more uniform and comprehensive, thus enhancing the decorative effect of the Christmas tree.

[0048] Ultrasonic welding technology replaces the hot-melt method. By using the support block 31 and the bar cylinder 42 to hold the bar, the ultrasonic welder 33 can firmly grip the bar at the welding position during the process of welding the yarn to the bar. This ensures that the ultrasonic welder 33 is in close contact with the yarn and the bar, thus achieving a full welding effect. This reduces the risk of branches falling off during use and ensures product quality. Compared with the hot-melt method for fixing yarn, the ultrasonic welder 33 acts directly on the yarn and the bar, and stops working directly when not welding, effectively reducing power consumption.

[0049] Please see Figure 2 and Figure 8 Both the first power mechanism 22 and the second power mechanism 46 include a first power motor 51 and a first synchronous pulley mechanism 52 connected to the first power motor 51. The first power motor 51 of the first power mechanism 22 is installed inside the machine body 10. The first power motor 51 is connected to the large-diameter winding tube 21 through the first synchronous pulley mechanism 52. The first power motor 51 of the second power mechanism 46 is installed on the fixed frame 44. The first power motor 51 is connected to the rigid air pipe 45 through the first synchronous pulley mechanism 52. The first power motor 51, installed inside the machine body 10, serves as the power source for the first power mechanism 22. It is connected to the large-diameter winding tube 21 through the first synchronous pulley mechanism 52. This layout allows for stable and efficient power transmission, ensuring that the large-diameter winding tube 21 rotates at a uniform speed, laying the foundation for the precise winding of yarn onto the bar stock. Furthermore, the internal installation saves external space, making the overall layout of the equipment more compact. The first power motor 51 of the second power mechanism 46 is placed on the fixed frame 44, and also uses the first synchronous belt pulley mechanism 52 to drive the rigid air pipe 45. This ensures that the rigid air pipe 45 drives the bar material to rotate stably, so that the yarn and rattan are wrapped more evenly and beautifully, improving the final decorative effect of the Christmas tree. Secondly, the unified power configuration mode reduces the types of equipment parts and maintenance difficulty. In case of failure, it is easier for technicians to troubleshoot and repair, improve overall production efficiency, and reduce downtime for maintenance.

[0050] Please see Figure 4The front end of the large-diameter winding tube 21 is connected to a bar stock pusher. The bar stock pusher includes a buffer frame 211 fixed to the outside of the large-diameter winding tube 21, a sleeve flange 212 movably connected to the inside of the large-diameter winding tube 21 and confined within the buffer frame 211, multiple guide rods 213 connected to the outside of the sleeve flange 212 and movably connected to the buffer frame 211, and a buffer spring 214 sleeved on the guide rods 213 and abutting against the sleeve flange 212 and the buffer frame 211. The bar stock adapter 23 is screwed to the front of the sleeve flange 212. The buffer frame 211 is fixed to the outside of the winding tube, providing stable support for the entire structure. The sleeve flange 212 is movably connected to the inside of the winding tube and confined by the buffer frame 211. Together with the multiple guide rods 213, it makes the moving parts of the pusher operate more accurately and stably. The buffer spring 214 is sleeved on the guide rod 213 and abuts against the sleeve flange 212 and the buffer frame 211. It can effectively buffer various sudden impacts, avoid damage to components caused by excessive impact force during bar docking and pushing, protect the equipment and extend its service life. The bar fitting 23 screws are connected to the sleeve flange 212, which not only facilitates disassembly and replacement and adapts to different sizes of bars, but also allows for fine-tuning of the position during assembly with the help of the buffer structure, making the docking of the bar and the winding tube smoother and more precise, improving the overall assembly efficiency and quality, and laying a solid foundation for subsequent stable and efficient branch binding operations.

[0051] Please see Figures 5-6 The power transfer module 34 includes a slider-mounted base 341 fixedly mounted on the machine body 10, a first sliding seat 342 slidably connected to the slider-mounted base 341, and a transfer cylinder 343 fixedly mounted on the slider-mounted base 341 for driving the first sliding seat 342 to slide along the slider-mounted base 341. The support block 31, the wire clamping cylinder 32, and the ultrasonic welder 33 are all fixedly mounted on the first sliding seat 342. The first sliding seat 342 is slidably connected to it, giving the support block 31, the wire clamping cylinder 32, and the ultrasonic welder 33 the ability to move flexibly. The transfer cylinder 343 is fixed to the slider-mounted base 341 and is responsible for driving the first sliding seat 342 to slide, so that the support block 31, the wire clamping cylinder 32, and the ultrasonic welder 33 can synchronously and accurately approach or move away from the bar stock along a predetermined route. This integrated design ensures the coordinated movement of all components, allowing for smooth operation of wire clamping, tightening, and welding, thus improving work efficiency. On the other hand, the compact layout reduces unnecessary space occupation, optimizes the overall structure of the equipment, and facilitates subsequent inspection and maintenance, reducing the difficulty of troubleshooting.

[0052] Please see Figure 3 and Figure 9A fixed sheet metal 421 is installed on the bar stock conveying platform 41. A bar stock abutting cylinder 42 is vertically installed on the fixed sheet metal 421. An abutting sheet metal 422 is connected to the piston end of the bar stock abutting cylinder 42, and the abutting sheet metal 422 is guided and engaged with the fixed sheet metal 421. A right-angle notch 423 is provided on the abutting sheet metal 422, which abuts and engages with the bar stock through the right-angle notch 423, so that the abutting sheet metal 422 and the support block 31 can jointly apply a clamping force to the bar stock. The installation of the fixed sheet metal 421 on the bar stock conveying platform 41 provides a stable mounting base for the bar stock abutting cylinder 42, making its vertical installation more secure. The abutting sheet metal 422 connected to the piston end of the bar stock abutting cylinder 42, in guide engagement with the fixed sheet metal 421, ensures that the movement trajectory of the abutting sheet metal 422 is accurate and stable, without deviation or shaking, greatly improving the reliability of the operation. The right-angle notch 423 on the sheet metal 422 abuts against the bar material and, together with the support block 31, can apply a clamping force to the bar material from multiple directions. This multi-angle and precise clamping method allows the bar material to be firmly held in the welding position during ultrasonic welding, enabling the ultrasonic welder 33 to make close contact with the yarn and the bar material for full welding, thus laying a solid foundation for the production of high-quality Christmas tree products.

[0053] Please see Figure 10 The linear conveying module 43 includes a linear guide rail 431 fixedly mounted on the bar conveying platform 41, a second synchronous pulley mechanism 432 mounted at the lower end of the bar conveying platform 41, a second power motor 433 mounted at the lower end of the bar conveying platform 41 for driving the second synchronous pulley mechanism 432, and a second sliding seat 434 slidably connected to the linear guide rail 431 and driven by the second synchronous pulley mechanism 432 and the second power motor 433. The linear guide rail 431 is firmly fixed on the bar conveying platform 41, laying a precise guiding foundation for the entire conveying process and ensuring that the movement path of subsequent components is stable and does not deviate. The second synchronous pulley mechanism 432 mounted at the lower end of the bar conveying platform 41, together with the second power motor 433 responsible for driving it, constitutes a stable and efficient power transmission system, which can continuously supply sufficient power for the conveying action. The second sliding seat 434 is not only slidably connected to the linear guide rail 431 to ensure smooth movement, but also achieves a transmission connection with the second power motor 433 through the second synchronous belt pulley mechanism 432. In this way, driven by the second power motor 433, the second sliding seat 434 can move precisely along a predetermined straight track, driving the connected components to move stably, creating good conditions for the bar to move back and forth and be precisely positioned, thereby allowing the area of ​​yarn and rattan wrapped on the bar to be precisely controlled, improving the overall quality and efficiency of Christmas tree tying operations.

[0054] Please see Figures 7-8The mounting frame 44 includes two bearing-bearing upright plates 441 spaced apart from each other. The two bearing-bearing upright plates 441 are fixedly mounted on the second sliding seat 434, and support plates 442, also fixed to the second sliding seat 434, are connected to both sides of each bearing-bearing upright plate 441. Protective covers 443 are connected to the two bearing-bearing upright plates 441 to seal the space between them. A rigid air pipe 45 is bearing-connected to the two bearing-bearing upright plates 441. A first power motor 51 is mounted on one of the bearing-bearing upright plates 441, and a first synchronous pulley mechanism 52 is positioned between the two bearing-bearing upright plates 441. The two bearing-bearing upright plates 441 are spaced apart and firmly fixed to the second sliding seat 434, providing a stable main frame for the entire structure and ensuring the stability of subsequent component installation. The support plates 442 on both sides further strengthen the connection between the mounting frame 44 and the second sliding seat 434, distributing the force and enabling it to bear a greater load. A protective cover 443 is added between the bearing plates 441 to provide protection, effectively preventing dust and foreign objects from entering, reducing the risk of damage to internal components, and extending the service life of the equipment. The rigid air pipe 45 is connected to the bearing plates 441 through bearings, ensuring smooth and stable rotation. The first power motor 51 is installed on one of the bearing plates 441, and is paired with the first synchronous pulley mechanism 52 located between the two. The layout is compact and reasonable, facilitating power transmission and allowing the rigid air pipe 45 to rotate accurately and stably, driving the bar stock to rotate.

[0055] Please see Figure 1 A material trough 13 is provided on the machine body 10 and is located next to the bar material docking and winding unit 20. When workers are tying Christmas tree branches, they can conveniently place the required bar material, Christmas branches and other loose parts in the material trough 13 without having to walk around to retrieve materials frequently. The material retrieval distance is greatly shortened, saving operation time and making the entire production process more compact and smooth, thereby effectively improving the overall production efficiency and optimizing the working experience.
