Description

Technical Field

[0001] The invention relates to the technical field of draw rope production equipment, in particular to a draw rope butt joint machine. Background Art

[0002] The drawstring is woven from chemical fiber materials and is widely used in automatic retractable hangers, curtain accessories and various decorative pendants. In these application scenarios, it is often necessary to connect the two ends of the drawstring to form a closed loop rope for use. At present, the market uses a hot melt connection method to connect the drawstrings. For example, CN101666049B discloses an electric control circulation rope production device. The two ends of the drawstring are first manually cut and then the drawstring is clamped by the device. After the two end faces of the drawstring are operated to be close, the heating body is lowered to heat the end faces. After the heating body is removed, the end faces are connected. This method has problems in the initial end face processing: the ends of the rope strands woven from chemical fiber materials are easily scattered, drawn, and the end faces are skewed after manual shearing; the rope strand ends are likely to explode after being manually sheared and then clamped with two faces pressed together. The hot melt section is started only after multiple steps of shearing. All of these will lead to a decrease in the hot melt effect and docking quality. In addition, the hot solution at both ends of the joint is directly connected, making it difficult for the joint point to be inconsistent with the thickness of the rope strands. After the hot melt is cooled, there are protruding condensed solids at the joint, which makes the joint rough and causes stumbling during use, causing the joint to easily fall apart under external force, affecting the service life and aesthetics. Summary of the invention

[0003] The present invention aims to overcome the shortcomings of the prior art that the rope shearing is rough and the end surface is uneven, which affects the service life and aesthetics, and provides a rope butt jointing machine that can accurately cut the end surface and make the butt joint smooth.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A rope docking machine comprises a base and a pair of linear guides. The lower surface of the linear guides is fixedly connected to the upper surface of the base. The linear guides are arranged parallel to each other. A guillotine, a heat fuser and a kneader are arranged from front to back on the symmetry axis between the pair of linear guides. The linear guides are movably connected to a slide. The slide is located above the linear guides. The slide is connected to a rope carrying platform. The rope carrying platform is arranged symmetrically on the left and right with the symmetry axis of the linear guides as the symmetry center.

[0006] The base is connected to a controller. The linear guide includes a track and a ball screw. The track carries the slide and guides the slide. The slide is meshed with the ball screw. The ball screw is connected to the stepper motor (not shown in the figure). The stepper motor is controlled by the controller to provide power to push the slide and drive the rope carrier to move forward and backward on the linear guide. A pair of rope carriers carry two rope ends for the pull rope to be connected. From front to back, they pass through a guillotine, a hot melter, and a kneader in turn. The end faces of the two rope ends are guillotined as required, and the rope ends are hot-melted before they are spread apart. After hot melting, they are immediately connected together to shape. The cutting, hot melting, and butt-jointing of the butt rope ends are completed in one go. The pull rope joints are firmly connected, flat, and there is no condensed solid protrusion, which improves the service life and aesthetics.

[0007] Preferably, the rope carrying platform is provided with a clamping plate, which is in the shape of a rectangular plate. A matching cover plate is provided on the upper surface of the clamping plate, which is in the shape of a rectangular plate. One end of the cover plate is rotatably connected to the rear end of the upper surface of the clamping plate, and the other end of the cover plate is connected to a rod-shaped push rod, and the other end of the push rod is suspended. A rotating shaft is fixed to the rear end of the clamping plate, and the lower end of the cover plate is rotatably connected to the rotating shaft. When the cover plate is opened, the angle between the cover plate and the clamping plate can exceed 90 degrees, which is convenient for placing and removing the pull rope. The push rod makes it easy to open and close the cover plate.

[0008] Preferably, the surfaces of the splint and the cover plate that match each other are provided with grooves, respectively, and the grooves penetrate the inner and outer sides of the splint and the cover plate, respectively. The rope carrying platform is provided with a pair of semi-circular clamping grooves, the outer surface of the clamping groove at one end is a cylindrical surface, and the outer surface of the other end is a frustum surface. The cylindrical surface of the outer surface of the clamping groove is fixed to the groove of the splint and the cover plate, and the outer surface of the clamping groove is a frustum surface, and one end thereof protrudes from the inner side of the splint and the cover plate. The splint and the cover plate cooperate, and a pair of clamping grooves are formed into a circular tube shape. The grooves are respectively placed in the middle of the upper surface of the splint and the front surface of the cover plate, and the grooves are rectangular grooves, and the grooves penetrate the left and right sides of the splint and the cover plate, that is, the length direction of the grooves is perpendicular to the direction of the linear guide rail. One groove connects one clamping groove. The outer surface of the clamping groove is fixedly connected to the inner wall of the groove, and the clamping groove protrudes from the groove, and the end section is trapezoidal. When the splint and the cover plate are covered, the inner surfaces of the clamping grooves of the splint and the cover plate are connected to form a circular tube. The inner circle of the circular tube clamp groove is connected to adapt to the outer surface of the draw rope, so that the draw rope is clamped without being overly compressed, and the rope end is subjected to less pressure and can remain flat without bursting, which is convenient for cutting, hot melting and docking.

[0009] Preferably, the slide is L-shaped, and a slide groove is provided at the lower end of the vertical part of the slide, and the slide groove is embedded with the linear guide rail. A cylinder is fixedly connected to the upper surface of the end of the horizontal part of the slide, and the horizontal part of the slide is connected with a connecting block, and the connecting block is in the shape of a plate, and the connecting block is provided with a through hole, and the connecting block is in a circular shape. The connecting block is sleeved with the horizontal part of the slide, and the inner side surface of the connecting block is fixed with the clamping plate, and the outer side surface of the connecting block is connected to the telescopic rod of the cylinder. The cylinder is controlled by the controller. The cylinder is used to change the distance between the two rope heads, and the structure is simple. The two rope heads will not be collided to cause the rope strands to be dispersed by external force, which ensures the compactness of the rope strands and makes the subsequent hot melt surface flat and evenly hot melted.

[0010] Preferably, a raised slider is fixedly connected to the lower end of the outer surface of the connection block, and the raised surface of the slider is an arc surface. A pair of push blocks are provided on the outer side of the linear guide rail with the axis of symmetry of the linear guide rail as the symmetry center. The push block is a rectangular block. The lower surface of the push block is fixedly connected to the base. The inner side surface of the push block is provided with a guide surface and a retaining surface. The guide surface forms an angle with the linear guide rail. The guide surfaces of a pair of push blocks are trapezoidal, with the small end facing the rear end of the linear guide rail. The front end of the retaining surface is smoothly connected to the rear end of the guide surface, and the rear end of the retaining surface is smoothly connected to the rear end surface of the push block. The retaining surface is parallel to the linear guide rail, and the slider is in contact with the inner side surface of the push block. The inner side surface of the push block is provided with a guide surface and a retaining surface, and the arc surface of the slider is in contact with the guide surface. For the distance from the clamping groove passing through the shearing machine to entering the kneader, the end surface of the clamping groove gradually approaches the axis of symmetry of the linear guide rail, so that the rope carrier is offset inward under the push of the slider, close to the hot melt ring, which is convenient for rapid melting of the cross section. The arc surface of the slider is in contact with the retaining surface, which is the path for the clamping groove to enter and exit the kneader. The end face of the clamping groove is parallel to the symmetry axis of the linear guide, so that the position of the pull rope head remains unchanged after melting and before and after docking, ensuring that the joint is fixed and not torn off.

[0011] Preferably, the guillotine machine is provided with a guillotine table, the guillotine table is columnar, the lower surface of the guillotine table is fixedly connected to the base, the upper surface of the guillotine table is provided with a knife groove, the knife groove is in the shape of "〔", an upper beam is provided above the guillotine table, the upper beam is provided with a guillotine, the upper end of the guillotine is telescopically connected to the upper beam, the lower end of the guillotine is an arc with a concave end face, the cross section of the guillotine is in the shape of "〔", and the guillotine matches the knife groove. The upper beam is provided with a telescopic cylinder, and the telescopic rod of the telescopic cylinder is fixed to the upper end of the guillotine. The telescopic cylinder is controlled by the controller to move, and when the clamping groove carries a pair of rope heads to the upper surface of the guillotine table, under the control of the controller, the telescopic rod of the telescopic cylinder pushes the guillotine down until the end of the guillotine is inserted with the knife, to ensure that the groove guillotine completely cuts off the rope head, and the rope head retained at the end of the clamping groove is close to a truncated cone. The guillotine mechanically shears the rope end, quickly shears and keeps the rope section flat without unraveling, completely cuts through the rope end, and is fast and neat, without fiber drawing or rope strand unraveling. The rope section is truncated, which is convenient for later hot melting, and will not produce condensed solids, ensuring that the melt surface is flat and beautiful.

[0012] Preferably, the kneader comprises a columnar column, the lower end of the column is fixed to the base, an upper shaping plate and a lower shaping plate are arranged on the upper part of the column, the upper shaping plate is in strip shape, the rear end of the upper shaping plate is fixed to the column, the front end of the upper shaping plate is suspended, the suspended end of the upper shaping plate is provided with an upper shaping groove with a concave end face, the groove bottom of the upper shaping groove is an arc surface, the opening end of the groove side wall of the upper shaping groove is located at the suspended end face of the upper shaping plate and is wedge-shaped, the lower shaping plate is in strip shape, the rear end of the lower shaping plate is movably connected to the column, the front end of the lower shaping plate is suspended, the suspended end of the lower shaping plate is a hook-shaped lower shaping groove, the inner wall of the lower shaping groove hook is an arc surface, the end of the lower shaping groove hook is wedge-shaped, the lower shaping plate moves up, and the upper shaping groove and the lower shaping groove are embraced into a cylindrical shape. The kneader is a metal structure, which can quickly conduct heat and shape the cooling rope docking interface. When the wedges at the ends of the upper and lower shaping grooves are in contact and closed, the solution is more easily wrapped in the arc surface, and it is difficult to flow into the gap, and no condensed solids will be produced. In addition, the width of the upper and lower shaping grooves is greater than the width of the interface, ensuring that the interface is fully kneaded during kneading, and the effect of the rope joint is more coordinated and beautiful with the rope as a whole.

[0013] Preferably, the hot melt comprises a hot melt ring and a heat holder, wherein the lower end of the heat holder is fixedly connected to the base and the upper end is fixedly connected to the hot melt ring, and the hot melt ring is a sheet-like structure formed by coiling an electric heating wire. When the hot melt ring is not working, the heat holder keeps the hot melt ring in a heated state, and when the draw rope needs to be welded, the hot melt ring immediately reaches a temperature that can melt the draw rope under the control of the controller to weld the draw rope joint. The hot melt ring does not need to go through a process of cooling and heating to reach the welding temperature, and the hot melt ring is instantly heated, so that the hot melting is rapid and effective, preventing the rope strands from spreading due to long shearing time, and improving the docking efficiency of the draw rope.

[0014] The beneficial effects of the present invention are as follows: the docking of the pull rope is automated and efficient. The two ends of the rope are precisely sheared, and the cross-section of the docking portion is consistent with that of other parts of the rope, thereby ensuring an aesthetic effect. The process from shearing to kneading the joint is fast and short, the hot-melt cross-section is uniform, there is no protruding condensed solid, the docking portion is smooth, and the service life of the pull rope is increased.
