Description

Technical Field

[0001] The invention relates to the technical field of binding equipment, and in particular to an adjustable automatic binding equipment. Background Art

[0002] After production, the roller shutter needs to be packed into a plastic packaging box before transportation. Most plastic packaging boxes are square tube structures with openings at the ends. After the roller shutter is loaded into the plastic packaging box, the end cover is inserted into the end opening of the plastic packaging box, and finally the end cover is stapled to the end opening of the plastic packaging box with a binder to complete the packaging.

[0003] At present, there are some automatic binding devices on the market, which are equipped with a clamp for fixing plastic packaging boxes and a binder for binding plastic packaging boxes. However, in actual use, it is found that the clamps and binders of such devices are often fixed, that is, they can only be adapted to a single specification of plastic packaging boxes. Once the model and size of the plastic packaging box change, they cannot be used, and the versatility is poor. Summary of the invention

[0004] The purpose of the present invention is to solve the problem that the clamps and binders of the binding equipment in the prior art are often fixed, that is, they can only be adapted to a plastic packaging box of a single specification. Once the model and size of the plastic packaging box change, they cannot be applied and have poor versatility.

[0005] In order to solve the above problems, the present invention provides an adjustable automatic binding device, comprising a base frame and further comprising: A trigger is arranged on the front side of the base frame; The cam is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts, each of which is provided with a plurality of camshafts, The front side of the base frame is connected with a bracket, the bracket is located below the clamping seat and extends forward, and the upper side of the bracket is provided with a shelf for placing workpieces; A binding assembly corresponds to each clamp seat, and the binding assembly includes a binder and a linear drive member. The linear drive member is connected to a base frame, and the binder is connected to an output end of the corresponding linear drive member and is driven by the linear drive member to approach or move away from the corresponding clamp seat. The binder has a nail head facing a positioning platform of the corresponding clamp seat. When the trigger is triggered, the linear drive member drives the binder to approach the positioning platform, and the binder binds the workpiece.

[0006] Compared with the prior art, the above scheme designs the clamp seat to be slidably connected to the front side of the base frame. When the model and size of the workpiece, such as a plastic packaging box, changes, the bolt is turned to a loose state and the adjusting disk is turned forward or reversed. At this time, the tail end of the connecting rod will push the clamp seat close to or away from the center of the adjusting disk, that is, the clamp seats will be close to or away from each other. After the adjustment is appropriate, the bolt is turned to a locked state, so that the positioning table of the clamp seat can adapt to and abut against the inner wall of workpieces of different models and sizes to fix the workpiece, effectively improving the versatility; and the binding assembly drives the binder to approach or move away from the corresponding clamp seat through the linear drive member, so that even if the spacing between the positioning tables of the clamp seat changes, the linear drive member can still ensure that the binder can bind the workpiece on the positioning table, which is simple and convenient to use.

[0007] In an improved solution, there are four clamping seats and they are respectively located at the upper, lower, left and right parts of the front side of the base frame, and the trigger is located in the middle part of the front side of the base frame. Considering that most plastic packaging boxes are square tube-shaped, four clamping seats are equipped, and the positioning platforms of the four clamping seats respectively abut and position the four inner walls of the plastic packaging box.

[0008] In an improved solution, a limit platform protruding backward is provided in the middle of the rear side of the adjusting disk, and a concave arc surface is provided at a position of the outer peripheral wall of the limit platform corresponding to the head end of each connecting rod. The head end of the connecting rod has a rounded corner so as to slide and abut against the corresponding arc surface, thereby ensuring that when the adjusting disk is rotated forward or reversed, the arc surface of the limit platform can support the head end of the connecting rod to a certain extent, thereby improving the structural stability.

[0009] In an improved solution, the adjustment disk is provided with a hexagonal column base extending backwards, so that the adjustment disk can be rotated by the cooperation of a wrench and the hexagonal column base, and the operation is simple and convenient.

[0010] In an improved solution, an assembly groove is provided at a position where the positioning platform is opposite to the nail head of the binder, and an insert is detachably connected to the assembly groove. The side of the insert facing the nail head of the binder is provided with a groove for guiding the bending of the binding line. The groove of the insert is easily worn due to frequent friction with the binding line. Therefore, the insert is designed to be detachably connected to the assembly groove, which facilitates replacement and maintenance.

[0011] In an improved solution, the binding assembly further comprises a wire drum, the wire drum is wound with binding wire, and the wire drum is used to continuously provide binding wire to the binder, thereby facilitating continuous binding. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] See also Figure 1-Figure 8 An embodiment of the present invention provides an adjustable automatic binding device, comprising a base frame 1, and further comprising: A trigger 2 is arranged on the front side of the base frame 1; The clamp assembly includes an adjusting disk 3 and at least two clamping seats 4, all of which are distributed around the trigger 2, and the clamping seats 4 are slidably connected to the front side of the base frame 1 along the radial direction with the trigger 2 as the center of the circle, and the clamping seats 4 protrude forward to have a positioning table 41 for the workpiece 8 to abut and position, the adjusting disk 3 is rotatably connected to the rear side of the base frame 1, and the rotation axis is along the front-to-back direction and coaxial with the trigger 2, the adjusting disk 3 is provided with connecting rods 31 distributed along the circumferential direction and corresponding to the clamping seats 4 one by one, the head end of the connecting rod 31 is rotatably connected to the outer edge of the adjusting disk 3, and the tail end is provided with an adjusting hole 31 1, a rotatable bolt 32 is arranged in the adjusting hole 311, the base frame 1 is provided with an elongated through hole 11 corresponding to the sliding track of the clamp seat 4, the clamp seat 4 is provided with a screw hole 42 facing the elongated through hole 11, the bolt 32 passes through the corresponding elongated through hole 11 and is screwed to the corresponding screw hole 42 of the clamp seat 4, when the bolt 32 is in a loose state, the adjusting disk 3 drives the connecting rod 31 to move by forward and reverse rotation, and the connecting rod 31 drives the clamp seat 4 to move closer or farther from each other through the bolt 32, and when the bolt 32 is in a locked state, the clamp seat 4 and the connecting rod 31 are locked relative to the base frame 1; The front side of the base frame 1 is connected with a bracket 7, the bracket 7 is arranged to avoid the clamp assembly, the bracket 7 is located below the clamp seat 4 and extends forward, and the upper side of the bracket 7 is provided with a shelf 71 for placing the workpiece 8, so that the workpiece 8 is supported by the shelf 71 of the bracket 7; The binding assembly corresponds to the clamping seat 4 one by one. The binding assembly includes a binder 5 and a linear drive 6. The linear drive 6 is connected to the base frame 1. The binder 5 is connected to the output end of the linear drive 6 of the same binding assembly and is driven by the linear drive 6 to approach or move away from the corresponding clamping seat 4. The binder 5 has a nail head 51 facing the positioning platform 41 of the corresponding clamping seat 4. When the trigger 2 is triggered, the linear drive 6 drives the binder 5 to approach the positioning platform 41, and the binder 5 binds the workpiece 8.

[0019] The above scheme designs the clamp seat 4 to be slidably connected to the front side of the base frame 1. When the model size of the workpiece 8, such as a plastic packaging box, changes, the bolt 32 is loosened by rotating the bolt 32 and the adjusting disk 3 is rotated forward or reversed. At this time, the tail end of the connecting rod 31 will push the clamp seat 4 close to or away from the center of the adjusting disk 3, that is, the clamp seats 4 will move closer to or away from each other. After the adjustment is appropriate, the bolt 32 is rotated to a locked state, so that the positioning platform 41 of the clamp seat 4 can adapt to and abut against the inner wall of workpieces 8 of different models and sizes to fix the workpiece 8, effectively improving the versatility; and the binding assembly drives the binder 5 to move closer to or away from the corresponding clamp seat 4 through the linear drive member 6, so that even if the spacing between the positioning platforms 41 of the clamp seat 4 changes, the linear drive member 6 can still ensure that the binder 5 can bind the workpiece 8 on the positioning platform 41, which is simple and convenient to use.

[0020] In this embodiment, the base frame 1 is roughly plate-shaped with one side facing forward and the other side facing backward. There are four clamping seats 4 and they are respectively located at the upper part, lower part, left part and right part of the front side of the base frame 1. The trigger 2 is located at the middle part of the front side of the base frame 1. Considering that most plastic packaging boxes are square tube-shaped, four clamping seats 4 are equipped. The positioning platforms 41 of the four clamping seats 4 respectively abut and position the four inner walls of the plastic packaging box. Correspondingly, the number of connecting rods 31 and binding components are both four. It should be understood that the number of clamping seats 4 can also be two as needed, or when the cross-sectional shape of the plastic packaging box is other polygonal, the number of clamping seats 4 can be increased or decreased accordingly.

[0021] The linear drive member 6 is preferably a pneumatic cylinder or an electric cylinder, and the cylinder bodies of the four linear drive members 6 are respectively fixed to the upper part, the lower part, the left part, and the right part of the base frame 1, and the four linear drive members 6 are all located on the side of the four clamping seats 4 facing away from the trigger 2. The four binders 5 are respectively connected to the cylinder rods of the four linear drive members 6. The structure of the binder 5 belongs to the prior art and will not be repeated here.

[0022] See also Figure 7 and Figure 8, regarding the bolt 32, the bolt 32 and the adjustment hole 311 can rotate relative to each other, the nut end of the bolt 32 is located at the rear side of the adjustment hole 311, and the screw end of the bolt 32 passes through the adjustment hole 311 and the elongated through hole 11 and is screwed to the screw hole 42 of the clamp seat 4. When the bolt 32 is rotated toward the clamp seat 4, the bolt 32 gradually changes to a locked state, at which time the clamp seat 4 and the connecting rod 31 are pressed toward the base frame 1 and locked relative to the base frame 1; when the bolt 32 is rotated away from the clamp seat 4, the bolt 32 gradually changes to a loosened state, and in the loosened state, the screw end of the bolt 32 is still in contact with the screw hole 42, and at this time the clamp seat 4 and the connecting rod 31 are movable relative to the base frame 1.

[0023] See also Figure 4 and Figure 5 As an optimization solution for the adjusting disk 3, a limit platform 33 protruding backward is provided in the middle of the rear side of the adjusting disk 3, and a concave arc surface 331 is provided at the position of the outer peripheral wall of the limit platform 33 corresponding to the head end of each connecting rod 31. In this embodiment, since there are four connecting rods 31, there are four arc surfaces 331. The head end of the connecting rod 31 has a rounded corner so as to slide and abut against the corresponding arc surface 331, thereby ensuring that when the adjusting disk 3 is rotated forward or reversed, the arc surface 331 of the limit platform 33 can support the head end of the connecting rod 31 to a certain extent, thereby improving the structural stability.

[0024] In addition, see Figure 2 It is also possible to provide a hexagonal column 34 extending backward on the rear side of the adjusting disk 3, so that the adjusting disk 3 can be rotated by the cooperation of a wrench and the hexagonal column 34, which is simple and convenient to operate.

[0025] See also Figure 1 As an optimization solution for the positioning platform 41, a mounting groove 411 is provided at the position of the positioning platform 41 opposite to the nail head 51 of the binder 5, and an insert 43 is detachably connected in the mounting groove 411. A groove 431 for guiding the bending of the binding line is provided on the side of the insert 43 facing the nail head 51 of the binder 5. The groove 431 of the insert is easily worn due to frequent friction with the binding line, so the insert is designed to be detachably connected in the mounting groove 411 to facilitate replacement and maintenance. Regarding the detachable connection between the insert 43 and the mounting groove 411, a buckle can be provided in the mounting groove 411 to clamp the insert 43 in the mounting groove 411, or the insert 43 can be fixed in the mounting groove 411 by screws in this embodiment.

[0026] As an improvement to the present embodiment, the binding assembly further comprises a wire drum 52 around which a binding wire is wound. The wire drum 52 is used to continuously provide the binding wire to the binder 5, thereby facilitating continuous binding.
