Description

Technical Field

[0001] This utility model relates to the technical field of binding equipment, and more specifically to an adjustable automatic binding device. Background Technology

[0002] After the roller shutter is manufactured, it needs to be packed into a plastic box before transportation. The plastic box is usually a square tube with an opening at the end. After the roller shutter is packed into the plastic box, the end cap is inserted into the end opening of the plastic box. Finally, the end cap is nailed to the end opening of the plastic box with a stapler to complete the packaging.

[0003] Currently, some automatic binding equipment exists on the market. This equipment is equipped with clamps for securing plastic packaging boxes and a stapler for binding the plastic packaging boxes. However, in actual use, it has been found that the clamps and stapler of this type of equipment are often fixed, meaning they can only be adapted to a single size of plastic packaging box. Once the model or size of the plastic packaging box changes, it becomes unusable, indicating poor versatility. Utility Model Content

[0004] The purpose of this invention is to address the problem that the clamps and binders in existing binding equipment are often fixed, meaning they can only be used with a single type of plastic packaging box. Once the size or model of the plastic packaging box changes, the equipment becomes unsuitable, resulting in poor versatility.

[0005] To address the aforementioned problems, this utility model provides an adjustable automatic binding device, including a base frame, and further comprising:

[0006] The trigger is located on the front side of the base frame;

[0007] A clamping assembly includes an adjusting plate and at least two clamping seats. All the clamping seats are distributed around the trigger, and each clamping seat is radially slidably connected to the front side of a base frame with the trigger as its center. Each clamping seat has a forward-protruding positioning platform for workpiece contact and positioning. The adjusting plate is rotatably connected to the rear side of the base frame, and its rotation axis is along the front-rear direction and coaxial with the trigger. The adjusting plate has connecting rods distributed circumferentially, each corresponding to a clamping seat. The first end of each connecting rod is rotatably connected to the outer edge of the adjusting plate, and the last end has an adjusting hole. A rotatable bolt is provided in the adjusting hole. The base frame has an elongated through hole corresponding to the sliding trajectory of the clamping seat. Each clamping seat has a screw hole facing the elongated through hole. The bolt passes through the corresponding elongated through hole and is screwed to the screw hole of the corresponding clamping seat. When the bolt is in a loose state, the adjusting plate drives the connecting rod to move by forward and reverse rotation, and the connecting rod drives the clamping seats to move closer or further apart through the bolt. When the bolt is in a locked state, the clamping seats and connecting rods are locked relative to the base frame.

[0008] A binding assembly, corresponding to each clamp, includes a binder and a linear drive. The linear drive is connected to the base frame. The binder is connected to the output end of the corresponding linear drive and is driven by the linear drive to move closer to or away from the corresponding clamp. The binder has a staple head facing the positioning table of the corresponding clamp. When the trigger is activated, the linear drive drives the binder to move closer to the positioning table, and the binder binds the workpiece.

[0009] Compared with existing technologies, the above solution designs the clamps to be slidably connected to the front of the base frame. When the size of the workpiece, such as a plastic packaging box, changes, the bolt is loosened by turning it, and the adjustment disc is rotated clockwise or counterclockwise. At this time, the end of the connecting rod will push the clamps closer to or away from the center of the adjustment disc, that is, the clamps will move closer to or away from each other. After the adjustment is appropriate, the bolt is turned to lock it, so that the positioning platform of the clamp can be adapted to and abut against the inner wall of workpieces of different sizes to fix the workpiece, effectively improving versatility. The binding assembly drives the binder to move closer to or away from the corresponding clamp through the linear drive, so that even if the distance between the positioning platforms of the clamps changes, the linear drive can still ensure that the binder can bind the workpiece on the positioning platform, which is simple and convenient to use.

[0010] In an improved embodiment, there are four clamps located on the upper, lower, left, and right sides of the front of the base frame, respectively. The trigger is located in the middle of the front of the base frame. Considering that most plastic packaging boxes are square tubes, four clamps are provided. The positioning platforms of the four clamps abut and position the four inner walls of the plastic packaging box.

[0011] In an improved embodiment, a rearwardly protruding limiting platform is provided at the center of the rear side of the adjusting disc. The outer peripheral wall of the limiting platform has a concave arc-shaped surface at a position corresponding to the first end of each connecting rod. The first end of the connecting rod has a rounded corner so as to slide and abut against the corresponding arc-shaped surface, thereby ensuring that when the adjusting disc is rotated clockwise or counterclockwise, the arc-shaped surface of the limiting platform can provide a certain degree of support for the first end of the connecting rod, thus improving the structural stability.

[0012] In an improved embodiment, the adjustment disc is provided with a rearwardly extending hexagonal column, so that the adjustment disc can be rotated by cooperating with a wrench and the hexagonal column, making the operation simple and convenient.

[0013] In an improved embodiment, the positioning platform is provided with an assembly groove at the position opposite to the staple head of the binder. An insert is detachably connected in the assembly groove. The side of the insert facing the staple head of the binder is provided with a groove for guiding the bending of the binding thread. The groove of the insert is prone to wear due to frequent friction with the binding thread. Therefore, by designing the insert to be detachably connected in the assembly groove, it is easy to replace and maintain.

[0014] In an improved embodiment, a bracket is connected to the front side of the base frame. The bracket is located below the clamp and extends forward. The upper side of the bracket is provided with a shelf for placing the workpiece, thereby supporting the workpiece through the shelf of the bracket.

[0015] In an improved embodiment, the binding assembly further includes a thread spool wound with binding thread, the spool being used to continuously supply binding thread to the binder, thereby facilitating continuous binding. Attached Figure Description

[0029] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0030] Please see Figures 1-8 An embodiment of this utility model provides an adjustable automatic binding device, including a base frame 1, and further comprising:

[0031] Trigger 2 is located on the front side of base frame 1;

[0032] The fixture assembly includes an adjusting disk 3 and at least two clamping seats 4. All clamping seats 4 are distributed around the trigger 2, and the clamping seats 4 are radially slidably connected to the front side of the base frame 1 with the trigger 2 as the center. The clamping seats 4 have a forward-protruding positioning platform 41 for the workpiece 8 to abut and be positioned. The adjusting disk 3 is rotatably connected to the rear side of the base frame 1, and its rotation axis is along the front-back direction and coaxial with the trigger 2. The adjusting disk 3 is provided with connecting rods 31 distributed circumferentially, corresponding to each clamping seat 4. The first 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 provided in the adjustment hole 311. The base frame 1 is provided with an elongated through hole 11 corresponding to the sliding trajectory of the clamp 4. The clamp 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 4. When the bolt 32 is in a loose state, the adjustment plate 3 drives the connecting rod 31 to move by forward and reverse rotation. The connecting rod 31 drives the clamp 4 to move closer or further away from each other by the bolt 32. When the bolt 32 is in a locked state, the clamp 4 and the connecting rod 31 are locked relative to the base frame 1.

[0033] The binding assembly corresponds to each clamp 4. 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 move closer to or away from the corresponding clamp 4. The binder 5 has a staple head 51 facing the positioning table 41 of the corresponding clamp 4. When the trigger 2 is triggered, the linear drive 6 drives the binder 5 to move closer to the positioning table 41, and the binder 5 binds the workpiece 8.

[0034] The above scheme designs the clamp 4 to be slidably connected to the front side of the base frame 1. When the size of the workpiece 8, taking a plastic packaging box as an example, changes, the bolt 32 is turned to a loose state, and the adjusting plate 3 is rotated clockwise or counterclockwise. At this time, the tail end of the connecting rod 31 will push the clamp 4 closer to or away from the center of the adjusting plate 3, that is, the clamps 4 will move closer to or away from each other. After the adjustment is appropriate, the bolt 32 is turned to a locking state, so that the positioning platform 41 of the clamp 4 can be adapted to and abut against the inner wall of the workpiece 8 of different sizes to fix the workpiece 8, effectively improving the versatility. The binding assembly drives the binder 5 closer to or away from the corresponding clamp 4 through the linear drive 6. So even if the distance between the positioning platforms 41 of the clamp 4 changes, the linear drive 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.

[0035] In this embodiment, the base frame 1 is generally plate-shaped with one side facing forward and the other side facing backward. There are four clamps 4, located at the upper, lower, left, and right sides of the front of the base frame 1, respectively. The trigger 2 is located at the center of the front of the base frame 1. Considering that plastic packaging boxes are mostly square tubes, four clamps 4 are provided. The positioning platforms 41 of the four clamps 4 respectively abut against and position the four inner walls of the plastic packaging box. Correspondingly, there are four connecting rods 31 and four binding components. It should be understood that, if needed, there can also be two clamps 4, or the number of clamps 4 can be increased or decreased accordingly when the cross-sectional shape of the plastic packaging box is another polygon.

[0036] The linear drive unit 6 is preferably a pneumatic cylinder or an electric cylinder. The cylinder bodies of the four linear drive units 6 are respectively fixed to the upper, lower, left, and right parts of the base frame 1, and all four linear drive units 6 are located on one side of the four clamps 4 facing away from the trigger 2. The four binders 5 are respectively connected to the cylinder rods of the four linear drive units 6. The structure of the binder 5 is prior art and will not be described in detail here.

[0037] See Figure 7 and Figure 8 Regarding bolt 32, bolt 32 can rotate relative to adjusting hole 311. The nut end of bolt 32 is located behind adjusting hole 311, and the screw end of bolt 32 passes through adjusting hole 311 and elongated through hole 11 and is screwed to screw hole 42 of clamp 4. When bolt 32 is rotated in the direction of clamp 4, bolt 32 gradually becomes locked. At this time, clamp 4 and connecting rod 31 are pressed against base frame 1 and locked relative to base frame 1. When bolt 32 is rotated away from clamp 4, bolt 32 gradually becomes loose. In the loose state, the screw end of bolt 32 is still in contact with screw hole 42. At this time, clamp 4 and connecting rod 31 can move relative to base frame 1.

[0038] See Figure 4 and Figure 5 As an optimization of the adjustment plate 3, a rearwardly protruding limiting platform 33 is provided in the middle of the rear side of the adjustment plate 3. The outer peripheral wall of the limiting platform 33 is provided with an inwardly concave arc-shaped surface 331 at the position corresponding to the first end of each connecting rod 31. In this embodiment, since there are four connecting rods 31, there are four arc-shaped surfaces 331. The first end of the connecting rod 31 has rounded corners so as to slide and abut against the corresponding arc-shaped surface 331, thereby ensuring that when the adjustment plate 3 is rotated forward or backward, the arc-shaped surface 331 of the limiting platform 33 can provide a certain degree of support for the first end of the connecting rod 31, thereby improving the structural stability.

[0039] In addition, see Figure 2 Alternatively, by setting a rearward-extending hexagonal column 34 on the rear side of the adjustment plate 3, the adjustment plate 3 can be rotated by cooperating with the hexagonal column 34 using a wrench, making the operation simple and convenient.

[0040] See Figure 1As an optimization of the positioning platform 41, the positioning platform 41 is provided with an assembly groove 411 at the position opposite to the staple head 51 of the binder 5. An insert 43 is detachably connected in the assembly groove 411. The side of the insert 43 facing the staple head 51 of the binder 5 has a groove 431 for guiding the bending of the binding thread. The groove 431 of the insert is prone to wear due to frequent friction with the binding thread. Therefore, by designing the insert to be detachably connected in the assembly groove 411, it is easy to replace and maintain. Regarding the detachable connection between the insert 43 and the assembly groove 411, a buckle can be provided in the assembly groove 411 to snap the insert 43 into the assembly groove 411, or, in this embodiment, the insert 43 can be fixed in the assembly groove 411 with screws.

[0041] As an improvement to this embodiment, a bracket 7 is connected to the front side of the base frame 1. The bracket 7 is set away from the clamping assembly. The bracket 7 is located below the clamping seat 4 and extends forward. The upper side of the bracket 7 is provided with a shelf 71 for placing the workpiece 8, thereby supporting the workpiece 8 through the shelf 71 of the bracket 7.

[0042] As an improvement to this embodiment, the binding assembly also includes a thread reel 52, on which binding thread is wound. The thread reel 52 is used to continuously supply binding thread to the binder 5, thereby facilitating continuous binding.
