Description

Technical Field

[0001] This utility model relates to the field of foam board production technology, and in particular to a strapping machine for foam board production. Background Technology

[0002] Foam board is a commonly used packaging material with lightweight, heat insulation, and cushioning properties. With its good impact resistance and formability, it is widely used in the storage and transportation of goods, effectively reducing the risk of bumps and damage. Strapping machines are used to secure and fix items. During the production and processing of foam boards, manufacturers often use foam board strapping machines to bundle stacks of foam boards. The strapping machine wraps the foam boards with strapping ropes or straps and applies tightness to lock them together, forming a neat and sturdy whole, preventing scattering or displacement during handling or storage.

[0003] In existing technologies, foam board bundling machines use bundling ropes or straps to bundle foam boards. While bundling ropes can bundle foam boards, existing foam board bundling machines lack a knot-melting mechanism, preventing the knots from being heat-fused and locked. During subsequent handling and transportation, the knots are prone to fraying, loosening, and coming undone due to vibration and snagging. While foam board bundling machines using straps solve the problems of fraying and loosening, the connections are not strong enough, and the heat-fused joints of the straps are prone to separation. Furthermore, the cost of using straps is higher than that of ordinary nylon bundling ropes.

[0004] Therefore, there is an urgent need to provide a strapping machine for foam board production to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a strapping machine for foam board production.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a strapping machine for foam board production is provided, including a base mechanism, an eagle beak knotter mechanism and a hot melt mechanism. A protective shell mechanism is fixed on the base mechanism, and a rope winding mechanism is also fixed on the base mechanism. The rope winding mechanism includes a drive motor, a rotating rod is fixed on the output shaft of the drive motor, and a tensioning rod is rotatably connected to the rotating rod. An eagle beak knotter mechanism is fixed on the base mechanism; The beak knotter mechanism is fixed with a hot-melt mechanism, which includes a servo motor. The output end of the servo motor is fixed with a rotating shaft, and the other end of the rotating shaft is fixed with a rotating mounting base. A cylinder is fixed on the rotating mounting base, a first rotating arm is fixed on the cylinder, a second rotating arm is fixed on the output end of the cylinder, and a heating plate is fixed at the end of the second rotating arm.

[0007] The present invention is further configured such that: the base mechanism includes a base plate, a control box is welded and fixed on the base plate, an operating table is welded to the top of the control box, a back plate is welded to the rear end of the base plate, a rope reel is welded and fixed to the rear end of the control box, a foot switch is provided on the base plate, and the foot switch is electrically connected to the control box.

[0008] Through the above technical solution, the control box is equipped with modules such as an industrial control computer, a transformer and a pressurized air source, which can supply air and electricity to the device. The control box can effectively protect its internal electrical modules, the rope reel can be used to prevent the rope from getting tangled, and the foot switch can make it easy for the operator to use both hands to adjust the position of the foam board.

[0009] The present invention is further configured such that: the protective shell mechanism includes a shell welded to the control box, and the shell has multiple hollowed-out grooves.

[0010] Through the above technical solution, the housing can effectively prevent accidental injury to the hands when the rope winding mechanism rotates, and can protect the rope winding mechanism from collisions with other objects. The hollow groove effectively reduces the weight of the device.

[0011] The present invention is further configured such that: the drive motor is fixed to the back plate; the rotating rod is provided with a first wire hole, a third wire hole and a fourth wire hole; the end of the tensioning rod is provided with a second wire hole; the rotating rod and the tensioning rod are elastically rotatably connected; and the drive motor is electrically connected to the control box.

[0012] Through the above technical solution, a torsion spring, spiral spring or elastic hinge can be used to achieve an elastic rotational connection between the rotating rod and the tensioning rod. During the process of bundling the foam board, the tensioning rod can ensure that the nylon rope remains taut at all times, and avoid the nylon rope from loosening due to loose bundling.

[0013] The present invention is further configured such that: a connecting rod is fixed to the end of the rotating rod, and a fifth threading hole is fixed to the end of the connecting rod.

[0014] With the above technical solution, through holes are opened on the back plate. When binding, the staff will pass the nylon binding rope through the through holes, the first threading hole, the second threading hole, the third threading hole, the fourth threading hole, and the fifth threading hole in sequence. When binding, the industrial control computer in the control box controls the drive motor to rotate the rotating rod one revolution, which can wrap the nylon binding rope around the foam.

[0015] The present invention is further configured such that: the eagle beak knotter mechanism includes a mounting bracket fixed on the control box, one end of the mounting bracket is fixed with a drive module, and the drive module is connected to an eagle beak knotter and a rope clamping module.

[0016] With the above technical solution, the drive module is equipped with a rope-cutting blade. After the rope winding mechanism wraps the nylon binding rope around the foam, the drive module drives the rope clamping module to limit the nylon binding rope. At this time, the eagle-beak knotting pliers can tie a knot in the nylon rope, and the rope-cutting blade can cut the knotted nylon rope.

[0017] The present invention is further configured such that: a first connecting frame and a second connecting frame are fixed on the mounting bracket, and a bearing is rotatably connected to the inner side of the second connecting frame.

[0018] With the above technical solution, the first connecting frame and the second connecting frame are aligned, and the outer ring of the bearing is fixed to the second connecting frame.

[0019] The present invention is further configured such that: the servo motor is fixed to the first connecting frame, a limit sleeve is fixed on the cylinder, a limit rod is slidably connected to the inner side of the limit sleeve, the end of the limit rod is fixed to the second rotating arm, and both the servo motor and the cylinder are electrically connected to the control box.

[0020] Through the above technical solution, the rotating mounting base is fixed to the inner ring of the bearing, so the cylinder can rotate relative to the second connecting frame. After the eagle beak knotter mechanism ties and cuts the nylon binding rope, the servo motor can drive the cylinder to rotate upward, so that the ends of the first and second rotating arms are aligned with the binding rope knot. At this time, the cylinder retracts, and the ends of the first and second rotating arms clamp the binding rope knot. The heating plate can then heat melt the rope knot. Subsequently, the cylinder extends, and the first and second rotating arms release the clamping of the rope knot. The heat-melted part of the rope knot cools and solidifies, thereby preventing the rope knot from loosening due to vibration or pulling during subsequent transportation and handling. During the rotation of the cylinder, the limit rod can effectively prevent the cylinder and its piston rod from rotating relative to each other. After the rope knot is heat melted, the servo motor will drive the cylinder to rotate downward and reset, thereby preventing the first and second rotating arms from interfering with the operation of the eagle beak knotter mechanism.

[0021] The beneficial effects of this utility model are as follows: 1. This utility model, through the setting of a heat-melting mechanism, enables the device to locally heat-melt the knot of the nylon rope after it is bundled, thereby effectively preventing the knot from loosening due to subsequent vibration or pulling of the foam board. 2. This utility model, through the setting of the rope winding mechanism, the rotating rod and the tensioning rod, ensures that the binding rope remains taut throughout the binding process, thus guaranteeing the stability of the binding.

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0025] Please see Figures 1-5A strapping machine for foam board production includes a base mechanism 1, a beak knotter mechanism 4, and a hot-melt mechanism 5. The base mechanism 1 includes a base plate 101, a control box 102 welded to the base plate 101, an operating platform 103 welded to the top of the control box 102, a back plate 104 welded to the rear end of the base plate 101, and a rope reel 105 welded to the rear end of the control box 102. A foot switch 106 is installed on the base plate 101 and electrically connected to the control box 102. The control box 102 contains modules such as an industrial control computer, a transformer, and a pressurized air source, enabling the device to... The control box 102 effectively protects the internal electrical modules, and the rope reel 105 can prevent the rope from getting tangled. The foot switch 106 allows the operator to easily adjust the position of the foam board with both hands. A protective shell mechanism 2 is fixed on the base mechanism 1. The protective shell mechanism 2 includes a shell 201 welded to the control box 102. The shell 201 has multiple hollow slots 202. The shell 201 can effectively prevent accidental injury to the operator's hands when the rope winding mechanism 3 rotates, and can protect the rope winding mechanism 3 from collisions with other objects. The hollow slots 202 effectively reduce the weight of the device.

[0026] like Figure 1 and Figure 3 As shown, a rope winding mechanism 3 is also fixed on the base mechanism 1. The drive motor 301 is fixed to the back plate 104. The rotating rod 302 has a first threading hole 304, a third threading hole 306, and a fourth threading hole 307. The tension rod 303 has a second threading hole 305 at its end. The rotating rod 302 and the tension rod 303 are elastically rotatably connected. The drive motor 301 is electrically connected to the control box 102. A connecting rod 308 is fixed to the end of the rotating rod 302. A fifth threading hole 309 is fixed to the end of the connecting rod 308. A torsion spring or a spiral spring can be used between the rotating rod 302 and the tension rod 303. A spring or elastic hinge is used to achieve an elastic rotational connection. During the binding of the foam board, the tension rod 303 can ensure that the nylon rope remains taut at all times, preventing the nylon rope from coming loose due to loose binding. The back plate 104 has through holes. When binding, the worker passes the nylon binding rope through the through holes, the first threading hole 304, the second threading hole 305, the third threading hole 306, the fourth threading hole 307, and the fifth threading hole 309 in sequence. During binding, the industrial control computer in the control box 102 controls the drive motor 301 to drive the rotating rod 302 to rotate one revolution, which can wrap the nylon binding rope around the foam.

[0027] like Figure 1 and Figure 4As shown, a beak knotter mechanism 4 is fixed on the base mechanism 1. The beak knotter mechanism 4 includes a mounting bracket 401 fixed on the control box 102. A drive module 402 is fixed to one end of the mounting bracket 401. A beak knotter pliers 403 and a rope clamping module 404 are connected to the drive module 402. A first connecting bracket 405 and a second connecting bracket 406 are fixed on the mounting bracket 401. A bearing 407 is rotatably connected to the inner side of the second connecting bracket 406. A rope cutting blade is provided on the drive module 402. After the rope winding mechanism 3 winds the nylon binding rope onto the foam, the drive module 402 drives the rope clamping module 404 to limit the nylon binding rope. At this time, the beak knotter pliers 403 can knot the nylon rope, and the rope cutting blade can cut the knotted nylon rope. The first connecting bracket 405 and the second connecting bracket 406 are aligned, and the outer ring of the bearing 407 is fixed to the second connecting bracket 406.

[0028] like Figure 1 and Figure 5 As shown, a hot-melt mechanism 5 is fixed on the beak knotter mechanism 4. The hot-melt mechanism 5 includes a servo motor 501. A rotating shaft 502 is fixed to the output end of the servo motor 501. A rotating mounting base 503 is fixed to the other end of the rotating shaft 502. A cylinder 504 is fixed on the rotating mounting base 503. A first rotating arm 506 is fixed on the cylinder 504. A second rotating arm 507 is fixed to the output end of the cylinder 504. A heating plate 508 is fixed to the end of the second rotating arm 507. The servo motor 501 is fixed to the first connecting frame 405. A limit sleeve 505 is fixed on the cylinder 504. A limit rod 509 is slidably connected to the inner side of the limit sleeve 505. The end of the limit rod 509 is fixed to the second rotating arm 507. Both the servo motor 501 and the cylinder 504 are electrically connected to the control box 102. The rotating mounting base 503 is fixed to the inner ring of the bearing 407. Therefore, the cylinder 504 can rotate relative to the second connecting frame 406. After the eagle beak knotter mechanism 4 knots and cuts the nylon binding rope, the servo motor 501 drives the cylinder 504 to rotate upward, so that the ends of the first rotating arm 506 and the second rotating arm 507 are aligned with the binding rope knot. At this time, the cylinder 504 retracts, and the ends of the first rotating arm 506 and the second rotating arm 507 clamp the binding rope knot. The heating plate 508 can then heat-melt the rope knot. Subsequently, the cylinder 504 extends, and the first rotating arm 506 and the second rotating arm 507 release the clamp on the rope knot. The heat-melted part of the rope knot cools and solidifies, thereby preventing the rope knot from loosening due to vibration or pulling during subsequent transportation and handling. During the rotation of the cylinder 504, the limit rod 509 can effectively prevent the cylinder 504 and its piston rod from rotating relative to each other. After the rope knot is heat-melted, the servo motor 501 drives the cylinder 504 to rotate downward and reset, thereby preventing the first rotating arm 506 and the second rotating arm 507 from interfering with the operation of the eagle beak knotter mechanism 4.

[0029] In use, the operator first places the binding rope coil on the rope reel 105, then arranges the binding rope on the winding mechanism 3, and connects its end to the eagle beak knotter mechanism 4. Then, the foam board to be bound is placed at the designated position on the operating table 103, and the foot switch 106 is pressed. At this time, the winding mechanism 3 can wind the binding rope around the foam board. Subsequently, the eagle beak knotter mechanism 4 ties the binding rope and cuts it. The heat-melting mechanism 5 can heat-melt the knot of the binding rope.
