Description

Technical Field

[0001] The utility model belongs to the technical field of binding equipment, and particularly relates to a novel double-head binding device. Background Art

[0002] Existing binding machines are generally of a single-body structure and only have one binding opening. When binding documents, it needs to be operated twice, which is time-consuming and laborious. Therefore, double-head binding devices have emerged on the market.

[0003] For example, the Chinese utility model patent with the authorization announcement number "CN206406001U" discloses a standard-format stapler. The standard-format stapler includes a base, two staplers installed on the base, two brackets provided on the outer sides of the two staplers on the base, a rotating shaft connected between the two brackets, a pressing handle fixedly connected to the rotating shaft, and a telescopic paper support provided on the base. A transverse positioning baffle for adjusting the parallel binding margin is provided on the telescopic paper support, positioning marks are provided on the telescopic paper support, and corresponding positioning marks are provided on the base. The utility model is provided with a telescopic paper support with positioning marks, and the telescopic paper support and the transverse positioning baffle are integrated, which can ensure the standardization of the text in a horizontal state during binding, and can also conveniently adjust the distance between the parallel binding and the text page margin. It has the advantages of simple structure, low production cost, convenient use, time-saving and labor-saving, etc.

[0004] The above stapler can achieve double binding with one press. However, since the pressing handle is directly rotatably connected to the bracket, the stress point during pressing is mainly concentrated on the pressing handle itself. After long-term use, the pressing handle is easily damaged and has a short service life. The structure of the stapler still needs to be further optimized.

[0005] In view of this, the applicant has conducted in-depth research on the above problems, and thus this case has been generated. Summary of the Invention

[0006] The purpose of the utility model is to provide a novel double-head binding device with a simple structure and a long service life.

[0007] In order to achieve the above purpose, the utility model adopts such a technical solution:

[0008] A new type of double - head binding device, including a base and support plates respectively fixed on both sides of the top of the base. At least two binding machines are arranged on the base, and the binding openings of the binding machines are flush with the top surface of the base. The positions between the binding openings of each binding machine form a binding channel. Two binding machines are arranged in parallel and at intervals between the two support plates. A T - shaped pressing handle for driving the two binding machines to complete the binding action is also arranged between the two support plates. The T - shaped pressing handle includes a horizontal part rotatably connected to the support plate and a vertical part for pressing. The horizontal part is located above the binding channel. Support blocks are also arranged between the two ends of the horizontal part and the corresponding support plates. The two support blocks are rotatably arranged on the support plates through a rotating rod. One end of the support block is sleeved on the rotating rod, and the other end is fixedly connected to the horizontal part. A first pressing roller is also penetrated through one side of the horizontal part corresponding to the binding machine. The first pressing roller is rotatably penetrated through both ends of the horizontal part. The first pressing roller is located on the top of the binding machine and abuts against the top surface of the binding machine. Both ends of the first pressing roller respectively extend out of the horizontal part and are fixedly connected to the corresponding support blocks.

[0009] Further, a second pressing roller is also penetrated through one side of the horizontal part corresponding to the binding machine. The second pressing roller is rotatably arranged at both ends of the horizontal part and is located above the first pressing roller. Both ends of the second pressing roller respectively extend out of the horizontal part and are fixedly connected to the corresponding support blocks.

[0010] Further, a protective cover is also arranged on the top of the support plate. An avoidance groove is opened in the middle of the protective cover. The avoidance groove is located above the binding channel and is opened towards the direction of the binding channel. The vertical part is rotatably arranged in the avoidance groove.

[0011] Further, a sliding groove with an open outer end is recessed in the middle of the top surface of the base. A limiting convex column is fixed in the middle of the top surface of the sliding groove. A bearing plate is slidably arranged in the sliding groove. A strip - shaped groove is opened in the middle of the bearing plate. The limiting convex column is located in the strip - shaped groove.

[0012] Further, a first limiting baffle is integrally formed on the top surface of one end of the bearing plate close to the binding machine. The thickness of the bearing plate is the same as the depth of the sliding groove.

[0013] Further, a limiting seat is slidably arranged on the side of the base. The limiting seat is arranged at the position of the base close to the binding channel. The limiting seat includes an insertion plate slidably arranged on the side of the base and a second limiting baffle integrally formed on the insertion plate. The second limiting baffle is arranged at one end of the insertion plate away from the base. A slot for the insertion plate to slide is opened on the side of the base.

[0014] By adopting the foregoing design solution, the beneficial effects of the present utility model are as follows:

[0015] By arranging a support block between the support plate and the T-shaped pressing handle, and the T-shaped pressing handle is rotationally connected to the rotating rod through the support block, the force of the T-shaped pressing handle can be dispersed through the support block during pressing, effectively reducing the concentrated force on the T-shaped pressing handle, avoiding the T-shaped pressing handle from bearing the load alone, and prolonging the service life of the T-shaped pressing handle.

[0016] Furthermore, a second pressing roller is arranged on the T-shaped pressing handle, and the second pressing roller is fixedly connected to the support block. The second pressing roller has a fixing effect on the support block, so that the force applied to the T-shaped pressing handle and the support block can be dispersed to the second pressing roller, thereby further dispersing the concentrated stress on the T-shaped pressing handle 2 to the support block 3 and the T-shaped pressing handle 2, avoiding the T-shaped pressing handle 2 from bearing the load alone, and prolonging its service life.

[0017] Furthermore, an avoidance groove is arranged on the protective cover, and the avoidance groove is opened in the direction of the binding channel, so that when the operator performs binding in front of the binding channel, the arm can exert force towards its own direction to press the T-shaped pressing handle, which is convenient for operation.

[0034] Next, in combination with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] As Figures 1 to 3 shown, a new type of double-head binding device includes a base 1 and support plates 11 respectively fixed on both sides of the top of the base 1. At least two binding machines 12 are arranged on the base 1. The two binding machines 12 are arranged in parallel at intervals between the two support plates 11. The binding machine 12 has a binding seat 13 for carrying the items to be bound, a staple box 14 for accommodating staples, and a pressing staple upper cover 15 for pressing the staples out of the staple box 14. There is a binding opening between the staple box 14 and the binding seat 13. The binding opening of the binding machine 12 is flush with the top surface of the base 1. The positions of the binding openings of the two binding machines 12 form a binding channel; it should be noted that the binding machine 12 in this embodiment can adopt a conventional binding machine 12 in the art. For example, the binding machine disclosed in the Chinese utility model patent with the publication number "CN211390650U" and the name "Protection device for staples of a binding machine". The above-mentioned binding seat 13, staple box 14, and pressing staple upper cover 15 are all conventional components in the binding machine.

[0036] A T-shaped pressing handle 2 for driving two binding machines 12 to complete the binding action is further arranged between the two support plates 11. Specifically, the T-shaped pressing handle 2 includes a horizontal portion 21 rotatably connected to the support plate 11 and a vertical portion 22 for pressing. The horizontal portion 21 is located above the binding channel of the binding machine 12. Support blocks 3 are further arranged between the two ends of the horizontal portion 21 and the corresponding support plates 11. The two support blocks 3 are rotatably arranged on the support plate 11 through a rotating rod 31. Specifically, the two ends of the rotating rod 31 are respectively rotatably arranged on the corresponding support plates 11. One end of the support block 3 is sleeved on the rotating rod 31, and the other end is fixedly connected to the horizontal portion 21 of the T-shaped pressing handle 2. A first pressing roller 23 is further arranged on one side of the horizontal portion 21 corresponding to the binding machine 12. The two ends of the first pressing roller 23 are respectively rotatably penetrated through the two ends of the horizontal portion 21, and the two ends of the first pressing roller 23 respectively extend out of the horizontal portion 21 and are fixedly connected to the corresponding support blocks 3. The first pressing roller 23 is located on the top of the nail pressing upper cover 15 and abuts against the top surface of the nail pressing upper cover 15.

[0037] During use, the item to be bound is placed on the binding seats 13 of the two binding machines 12. The vertical portion 22 of the T-shaped pressing handle 2 is pressed. Under the pressing action of the vertical portion 22, the horizontal portion 21 drives the support block 3 to rotate around the rotating rod 31. The first pressing roller 23 rolls on the binding machine 12 under the pressing action and presses the nail pressing upper cover 15 downward to complete a binding operation. Through the rolling of the first pressing roller 23, wear on the binding machine 12 and the T-shaped pressing handle 2 during the binding process can be avoided, and at the same time, the pressing effectiveness and stability of the binding machine 12 can be ensured.

[0038] In the double-headed binding device of the present utility model, by arranging the support block 3 between the support plate 11 and the T-shaped pressing handle 2, and the T-shaped pressing handle 2 is rotatably connected to the rotating rod 31 through the support block 3, the force of the T-shaped pressing handle 2 can be dispersed through the support block 3 during pressing, effectively reducing the concentrated force on the T-shaped pressing handle 2 and prolonging the service life of the T-shaped pressing handle 2.

[0039] Further, a second pressing roller 24 is also passed through one side of the transverse portion 21 corresponding to the binding machine 12. The second pressing roller 24 is rotatably arranged at both ends of the transverse portion 21 and is located above the first pressing roller 23. Both ends of the second pressing roller 24 respectively extend out of the transverse portion 21 and are fixedly connected to the corresponding support blocks 3. The second pressing roller 24 is arranged on the T-shaped pressing handle 2, and the second pressing roller 24 is fixedly connected to the support blocks 3. The second pressing roller 24 has a fixing effect on the support blocks 3, so that the force applied to the T-shaped pressing handle 2 and the support blocks 3 can be dispersed to the second pressing roller 24, thereby further dispersing the concentrated stress on the T-shaped pressing handle 2 to the support blocks 3 and the T-shaped pressing handle 2 when the T-shaped pressing handle 2 is pressed, avoiding the T-shaped pressing handle 2 bearing alone and extending its service life.

[0040] In the present utility model, a protective cover 4 is further provided on the top of the support plate 11. A relief groove 41 is provided in the middle of the protective cover 4. The relief groove 41 is located above the binding channel. The relief groove 41 is opened in the direction of the binding channel of the binding machine 12. The vertical portion 22 is rotatably arranged in the relief groove 41. The relief groove 41 is mainly used for the movement when the T-shaped pressing handle 2 is pressed, avoiding the protective cover 4 affecting the vertical portion 22 of the T-shaped pressing handle 2. The relief groove 41 of the present utility model is opened in the direction of the binding channel of the binding machine 12. Such a setting enables the operator to exert force towards his own direction to press the T-shaped pressing handle 2 when binding in front of the binding channel, which is convenient for operation.

[0041] Further, a sliding groove 17 with an open outer end is concavely provided in the middle of the top surface of the base 1. A limiting convex column 171 is fixed in the middle of the top surface of the sliding groove 17. A bearing plate 18 is slidably arranged in the sliding groove 17. A strip-shaped groove 181 is provided in the middle of the bearing plate 18. The limiting convex column 171 is located in the strip-shaped groove 181; a first limiting baffle 182 is integrally formed on the top surface of one end of the bearing plate 18 close to the binding machine 12. The thickness of the bearing plate 18 is the same as the depth of the sliding groove 17.

[0042] A limiting seat 19 is slidably arranged on the side of the base 1. The limiting seat 19 is arranged at a position on the side of the base 1 close to the binding channel of the binding machine 12. The limiting seat 19 includes a plug board 191 slidably arranged on the side of the base 1 and a second limiting baffle 192 integrally formed on the plug board 191. The second limiting baffle 192 is arranged at one end of the plug board 191 away from the base 1. The horizontal position of the top surface of the second limiting baffle 192 is higher than the horizontal position of the top surface of the base 1. A slot for the plug board 191 to slide is provided on the side of the base 1, so that the plug board 191 can move in the slot to adjust the distance between the second limiting baffle 192 and the base 1.

[0043] The bearing plate 18 can move within the sliding groove 17, driving the first limit baffle 182 to move. The position of the first limit baffle 182 within the binding channel determines the depth of the item to be bound that can be placed in the binding machine 12. The first limit baffle 182 and the second limit baffle 192 can respectively ensure that the two edges of the item to be bound are aligned, so as to ensure the effectiveness and reliability of the binding operation. Moreover, according to different binding requirements, the positions of the first limit baffle 182 or the second limit baffle 192 can be adjusted to improve its scope of application.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
