Description

TECHNICAL FIELD

[0001] The utility model relates to the field of coil binding device, especially to a binding machine. BACKGROUND

[0002] In the traditional binding method, the coil is first threaded through the binding holes of each medium (for example, paper, photo, etc.), and then the coil is manually pressed into a closed shape. However, this binding method not only has low work efficiency, but also has the problem that the coil cannot be completely pressed into a closed shape, and the accommodation during use causes the medium to fall off the coil.

[0003] Therefore, the Chinese utility model patent with the patent number ZL202121180841.7 (the authorized announcement number CN217347268U) discloses a binding machine, which includes a bracket, the bracket is provided with a guide block for fixing the coil, a clamping assembly for clamping the coil, and a pressing assembly for pressing the coil, the clamping assembly is located above the guide block, the pressing assembly includes a pressing rod, a buckle plate, and a connecting plate, the pressing rod passes through the coil along the axial direction of the entire coil, one end of the pressing rod is fixed to the connecting plate, and the other end is close to the buckle plate, the buckle plate is movably fixed to the connecting plate, and the connecting plate is movably fixed to the bracket. Compared with the traditional binding method, the above-mentioned patent improves the convenience of binding and improves the efficiency of binding, but the binding machine can only be used to bind the coil with a fixed size.

[0004] In addition, in order to realize the binding of the medium, it is necessary to punch holes on the medium first, and then use the coil to bind the medium together. In order to realize the functions of punching and binding, it is necessary to configure a puncher and a binding machine at the same time. However, the simultaneous configuration of the puncher and the binding machine not only has high cost, but also is troublesome to operate, which affects the use experience.

[0005] To this end, the Chinese utility model patent with the patent number ZL99204863.X (the authorized publication number CN2362670Y) discloses a paper punching and binding combined device, which comprises a casing, a punching device, an elastic load pressing plate, a coil pressing device and an adjustable cam brake, the punching device is provided with a tool holder and a plurality of punching tools, each tool is provided with a sliding baffle, and whether to punch with the tool holder can be selected, the elastic load pressing plate is pivotally arranged on a front end shaft of the casing, and it assists the layered paper to pass through the spiral coil, the coil pressing device is fixedly provided with a second handle at the second rotating shaft end, and a transmission gear is arranged to engage with the second tooth row of the L-shaped pressing plate, so that the open spiral coil is pressed and clamped into a closed spiral coil, and the adjustable cam brake is in contact with the protruding part of the L-shaped pressing plate. It can be seen that although the above patent assembles the punching function and the binding function on the same device, the structure is complex, and only the punching function and the binding function are simply combined, both of which are independent in structure and function, and the operation is still troublesome, for example, the user needs to operate the first handle when punching, and the user needs to operate the second handle when pressing. Utility model content

[0006] The first technical problem to be solved by the utility model is to provide a binding machine capable of binding coils of various sizes.

[0007] The second technical problem to be solved by the utility model is to provide a binding machine capable of binding coils of various sizes, and the binding machine also has a punching function, and the punching function and the binding function are integrated.

[0008] The technical scheme adopted by the utility model to solve at least one of the above technical problems is as follows: a binding machine comprises a base, and the top surface of the base is provided with:

[0009] a first pressing member;

[0010] a second pressing member, which is arranged opposite to the first pressing member, and has an initial spacing with the first pressing member in an initial state;

[0011] an adjusting mechanism, which is used to drive the second pressing member to adjust the initial spacing between the second pressing member and the first pressing member, and make the initial spacing match the size of the coil to be pressed;

[0012] a pressing driving member, which is used to drive the first pressing member to move towards the second pressing member in the initial state to press the coil between the first pressing member and the second pressing member.

[0013] Further, the first and second pressing members are both long strip-shaped plates, and are vertically and oppositely arranged along the horizontal direction, so that the coil is arranged in the gap between the two. Through the design of the specific shape of the first and second pressing members and the specific arrangement of the two, the two can better cooperate to press the coil.

[0014] Further, the distance between the upper ends of the first and second pressing members is smaller than the distance between the lower ends of the two. Thus, the coil can be prevented from being squeezed out of the gap between the first and second pressing members during pressing.

[0015] Further, the pressing surface of the first pressing member and the pressing surface of the second pressing member are respectively inclined inward along the length direction of the pressing member from bottom to top. Thus, the coil can be positioned between the first and second pressing members, and the coil can be better prevented from being squeezed out of the gap between the two during pressing.

[0016] Further, the pressing surface of the first pressing member and the pressing surface of the second pressing member are respectively provided with anti-skid pads along the length direction of the pressing surface. The anti-skid pads increase the friction between the coil and the pressing surfaces on both sides, so that the coil is prevented from moving (including being squeezed out upward) during pressing, thereby affecting the pressing effect.

[0017] Further, the first and second pressing members are both long strips and are respectively arranged in parallel along the horizontal direction. The adjusting mechanism comprises:

[0018] an adjusting plate arranged along the horizontal direction and fixed to one side of the second pressing member;

[0020] a moving shaft which can be movably positioned along the direction parallel to the length direction of the second pressing member, and is vertically and continuously arranged in the adjusting hole and can move along the length direction of the adjusting hole to drive the adjusting plate. Thus, when the moving shaft moves, the adjusting plate can be driven to move along the direction of the distance between the first and second pressing members, thereby driving the first pressing member to move towards the second pressing member or to move away from the second pressing member, so as to change the size of the initial distance between the two. Moreover, when the coil is pressed, the moving shaft is limited along the direction of the distance between the first and second pressing members, so that the second pressing member is prevented from being displaced due to the movement of the moving shaft.

[0021] Further, the adjusting mechanism further comprises a guide slot formed on the base and extending along a direction parallel to the length direction of the second pressing member, and one end of the moving shaft is embedded in the guide slot and can move back and forth along the guide slot. The cooperation between the moving shaft and the guide slot limits the moving shaft in the guide slot and enables the moving shaft to move back and forth along a direction parallel to the length direction of the second pressing member.

[0024] Further, one side of the boss is provided with a mounting opening extending along the length direction of the second pressing member, the second pressing member is a plate member vertically arranged in the horizontal direction and can shield the mounting opening, the corresponding surfaces of the adjusting plate and the second pressing member are fixed along the length direction, and the other side of the boss is provided with a long and strip-shaped guide opening, the length direction of the guide opening is parallel to the length direction of the second pressing member, and one end of the moving plate is provided with a knob embedded in the guide opening and can move back and forth along the guide opening. Thus, the overall structure of the adjusting mechanism can be more compact, and the moving shaft can move more stably, thereby ensuring the stable movement of the first pressing member driven by the adjusting plate, and further ensuring the reliability of the initial spacing adjustment between the first pressing member and the second pressing member. In addition, the knob facilitates the movement of the moving plate, thereby facilitating the adjustment of the initial spacing.

[0025] Further, when the knob is located at one end of the guide opening, the moving shaft is located at one end of the adjusting hole, the second pressing member shields the mounting opening, and the spacing between the second pressing member and the first pressing member is maximum, and when the knob is located at the other end of the guide opening, the moving shaft is located at the other end of the adjusting hole, the second pressing member is located outside the mounting opening, and the initial spacing between the second pressing member and the first pressing member is minimum. Thus, the first pressing member can be stably arranged in the initial state and the state with the minimum initial spacing.

[0026] Further, the pressing driving member is rotationally arranged on the top surface of the base and is provided with an elastic reset member, and the first pressing member is linked with the pressing driving member through a transmission mechanism,

[0027] In the initial state, the coil to be compressed is placed in the gap between the first and second compression members, and the compression driving member is rotated downward, which drives the first compression member to move towards the second compression member to compress the coil placed between the first and second compression members, and the elastic return member is deformed to make the compression driving member have a tendency to rotate upward to return to its initial state. Thus, the rotation of the compression driving member can drive the first compression member, and the compression driving member is automatically reset under the action of the elastic return member after compression, which is convenient to operate and helps to improve the use experience.

[0028] Further, the top surface of the base is also provided with a punching mechanism, which comprises a handle that can rotate up and down and a punch core, wherein the handle can press the punch core to realize punching, the compression driving member is the handle, and the elastic return member is a torsion spring installed on the rotating shaft of the handle.

[0029] Further, the transmission mechanism comprises a cam, a transmission gear set and a transmission rack, wherein the cam is arranged at the end of the connecting end of the handle and can rotate around the rotating shaft of the handle, the transmission gear set comprises a first transmission gear engaged with the cam and a second transmission gear engaged with the transmission rack, the first transmission gear is engaged with the second transmission gear, the transmission rack is connected with the first compression member and extends along the distance between the first and second compression members, and rotating the handle can drive the transmission rack to move back and forth along the length direction of the transmission rack. Thus, the rotation of the handle drives the transmission gear set through the cam thereon, and drives the transmission rack through the transmission gear set to realize the movement of the first compression member, so that the handle is transmitted to the first compression member.

[0030] Further, the first compression member is a long strip-shaped plate member arranged vertically along the horizontal direction, the lower end of the first compression member is provided with a horizontally extending sliding bottom plate, the two sides of the sliding bottom plate are respectively provided with the transmission racks, and the sliding bottom plate can move back and forth along the length direction of the transmission racks,

Through the above design, the first pressing member can be driven by the handle to move back and forth along the direction of the distance between the first pressing member and the second pressing member.

[0032] Further, the bottom surface of the gear base is a plane and is slidably matched with the top surface of the sliding bottom plate, and the bottom of the gear base is provided with a rollable ball, the ball is at least partially exposed on the bottom surface of the gear base, and the lowest part of the ball protrudes below the bottom surface of the gear base.

[0033] Further, one side of the base is provided with a row of hanging columns arranged in a straight line and used for hooking the coil along the length direction.

[0034] Further, the base further comprises a baffle, the top surface of the base is provided with an insertion hole for vertically inserting the baffle, and in the state that the baffle is inserted on the top surface of the base, the baffle can abut against the side edge of the medium to position the medium. The baffle is used for positioning the medium, which is beneficial to ensure the accuracy of the punching position.

[0035] Further, the baffle is in a strip shape, both ends of the baffle are respectively provided with an insertion column extending along the width direction of the baffle, the insertion hole is arranged on the top surface of the base and is respectively used for inserting each insertion column, and each insertion hole is arranged in a preset array, in the array, the insertion column at one end of the baffle is inserted into the corresponding insertion hole according to the working position of the medium, and the insertion column at the other end can always be inserted into the corresponding another insertion hole.

[0054] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0055] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Since the embodiments disclosed in this utility model can be arranged in different directions, these terms indicating direction are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0056] like Figures 1 to 15 As shown, a binding machine includes a base 1. A first pressing member 21, a second pressing member 22, an adjusting mechanism 3, and a pressing drive are respectively disposed on the top surface of the base 1. The second pressing member 22 is disposed opposite to the first pressing member 21, and initially, there is an initial gap between them. The adjusting mechanism 3 drives the second pressing member 22 to adjust the initial gap between it and the first pressing member 21, matching the size of the initial gap to be pressed. The pressing drive drives the first pressing member 21 to move towards the second pressing member 22 in the initial state to press the coil between them.

[0057] As can be seen, the utility model discloses a first pressing part 21 and the initial spacing size between the second pressing part 22 are adjusted by the adjusting mechanism 3, and the initial spacing size is matched with the size of the coil to be pressed, and the coil between the first pressing part 21 and the second pressing part 22 is pressed by the pressing driving part to drive the first pressing part 21 to move to the direction of the second pressing part 22. It can be seen that the utility model can realize the pressing of various different size coils (6.4mm-16mm), thereby realizing the binding of products using different size coils, such as notebook, calendar, photo album and the like.

[0058] Preferably, the first pressing part 21 and the second pressing part 22 are both long strip-shaped plate members, and are vertically arranged in the left-right direction, so that the coil is arranged in the gap between the two along the length direction of the coil, as shown in Figure 1 and Figure 7 The specific shape of the first pressing part 21 and the second pressing part 22 and the specific arrangement manner of the two can better cooperate to press the coil.

[0059] Further preferably, as shown in Figure 7 The spacing between the upper ends of the first pressing part 21 and the second pressing part 22 is smaller than the spacing between the lower ends of the two, so that the coil can be prevented from being extruded out of the first pressing part 21 and the second pressing part 22 during the pressing process. In the embodiment, specifically, the pressing surface of the first pressing part 21 and the pressing surface of the second pressing part 22 are respectively inclined inwardly from bottom to top along the length direction of the pressing part, so that the coil can be positioned between the first pressing part 21 and the second pressing part 22, and the coil can be better prevented from being extruded out of the two during the pressing process. Preferably, the pressing surface of the first pressing part 21 and the pressing surface of the second pressing part 22 are respectively provided with anti-skid pads 211, 221 along the length direction of the pressing surface. The anti-skid pads 211, 221 can increase the friction between the coil and the two pressing surfaces, so that the coil can be prevented from moving (including being extruded upward) during the pressing process, thereby affecting the pressing effect.

[0060] Further, as shown in Figure 4 and Figure 5 The adjusting mechanism 3 comprises an adjusting plate 31, an adjusting hole 311 and a moving shaft 32. The adjusting plate 31 is arranged in the horizontal direction and fixed to one side of the second pressing part 22. The adjusting hole 311 is long strip-shaped and arranged on the adjusting plate 31, and the length direction of the adjusting hole 311 intersects with the length direction of the second pressing part 22 and is inclined to one side from the length direction of the second pressing part 22. In the embodiment, specifically, the second straight line extends in the left-right direction, the third straight line extends in the front-back direction, and the first straight line extends to the left from front to back.

[0061] Further, the moving shaft 32 is limitedly movable in the direction parallel to the length direction of the second pressing member 22, and is vertically inserted into the adjusting hole 311 and movable along the length direction of the adjusting hole 311 to drive the adjusting plate 31. Thus, when the moving shaft 32 moves, the adjusting plate 31 is driven to move along the direction of the interval between the first pressing member 21 and the second pressing member 22, thereby driving the first pressing member 21 to move towards the second pressing member 22 or to move away from the second pressing member 22, so as to change the size of the initial interval therebetween. Moreover, when the coil is pressed, since the moving shaft 32 is limitedly movable along the direction of the interval between the first pressing member 21 and the second pressing member 22, the displacement of the second pressing member 22 caused by the movement of the moving shaft 32 can be avoided.

[0062] Preferably, as shown in Figure 5 , the adjusting mechanism 3 further comprises a guide slot 111 formed on the base 1, the guide slot 111 extends in the direction parallel to the length direction of the second pressing member 22, and one end of the moving shaft 32 is embedded in the guide slot 111 and movable along the guide slot 111. The cooperation between the moving shaft 32 and the guide slot 111 limits the moving shaft 32 in the guide slot 111, and realizes the limited movement in the direction parallel to the length direction of the second pressing member 22. In addition, the adjusting mechanism 3 further comprises a moving plate 33, which extends horizontally and is arranged on the upper side or the lower side of the adjusting plate 31, and the moving shaft 32 is installed on the moving plate 33, which is conducive to the stable arrangement of the moving shaft 32.

[0063] In this embodiment, as shown in Figure 1 , Figure 6 and Figure 7 , one side of the top surface of the base 1 is provided with a hollow boss 11, the adjusting plate 31, the moving plate 33 and the moving shaft 32 are all accommodated in the inner cavity of the boss 11, and the inner top surface and the inner bottom surface of the boss 11 are respectively provided with the guide slot 111, and the upper and lower ends of the moving shaft 32 are respectively embedded in the corresponding guide slot 111 and movable along the corresponding guide slot 111. The adjusting plate 31 is two pieces, and the two adjusting plates 31 are arranged in an upper and lower interval, and the moving plate 33 is clamped between the two adjusting plates 31, so as to facilitate the stable movement of the moving plate 33, and the adjusting hole 311 is formed on each adjusting plate 31, and the upper and lower ends of the moving shaft 32 on the moving plate 33 are respectively inserted into the adjusting hole 311 of the corresponding adjusting plate 31.

[0064] Furthermore, one side of the aforementioned boss 11 is a vertical wall with a mounting opening 113 extending laterally. The aforementioned second pressing member 22 is a vertically arranged plate that can cover the mounting opening 113, and the corresponding surfaces of each of the aforementioned adjusting plates 31 and the second pressing member 22 are fixed along the length direction. In this embodiment, preferably, each adjusting plate 31 and the second pressing member 22 are integral parts (e.g., Figure 5 (As shown). A long, narrow guide opening 112 extends through the other side of the aforementioned boss 11. The length direction of the guide opening 112 is parallel to the length direction of the aforementioned second pressing member 22. A lever 34 protrudes from one end of the aforementioned moving plate 33. The lever 34 is embedded in the guide opening 112 and can move back and forth along the guide opening 112. Figure 2 As shown. This allows for a more compact overall structure of the adjustment mechanism 3 and a smoother movement of the moving shaft 32, ensuring the smooth movement of the first pressing member 21 driven by the adjustment plate 31, and consequently ensuring the reliability of the initial distance adjustment between the first pressing member 21 and the second pressing member 22. Furthermore, the presence of a toggle block 34 facilitates the movement of the moving plate 33, thereby enabling easier adjustment of the initial distance.

[0065] Furthermore, when the aforementioned lever 34 is located at one end of the aforementioned guide port 112, the aforementioned moving shaft 32 is located at one end of the adjusting hole 311, the aforementioned second pressing member 22 covers the aforementioned mounting port 113, and the distance between the second pressing member 22 and the first pressing member 21 is at its maximum. When the lever 34 is located at the other end of the aforementioned guide port 112, the aforementioned moving shaft 32 is located at the other end of the adjusting hole 311, the aforementioned second pressing member 22 is located outside the aforementioned mounting port 113, and the initial distance between the second pressing member 22 and the first pressing member 21 is at its minimum, thereby stabilizing the first pressing member 21 in its initial state and in the state with the minimum initial distance.

[0066] Furthermore, preferably, the aforementioned pressing drive is rotatably mounted on the top surface of the base 1 and is equipped with an elastic reset member, and is linked to the first pressing member 21 via a transmission mechanism 5. In the initial state, the coil to be pressed is placed into the gap between the first pressing member 21 and the second pressing member 22. The pressing drive is rotated downwards, causing the first pressing member 21 to move towards the second pressing member 22, thus pressing the coil placed between them. The elastic reset member deforms, causing the pressing drive to tend to rotate upwards and return to its initial state. In this way, the rotation of the pressing drive can drive the first pressing member 21, and after pressing, the pressing drive automatically resets under the action of the elastic reset member, making operation convenient and improving the user experience.

[0067] Further, the binding machine in the embodiment further has a punching function, and therefore the top surface of the base 1 is further provided with a punching mechanism 4, which comprises a handle 41 and a punch core 42, as shown in Figure 6 . The handle 41 can press the punch core 42 to realize punching. The pressing driving part is the handle 41, and the elastic reset part is a torsion spring 43 installed on the rotating shaft 410 of the handle 41. It can be seen that the handle 41 of the punching mechanism 4 is used as the pressing driving part, and the handle 41 can realize binding operation while realizing punching driving. The punching function and the binding function are deeply integrated, which is beneficial to realize the simple internal structure of the device.

[0068] Further, in the embodiment, as shown in Figure 7 , Figure 11 , Figure 13 , Figure 14 and Figure 15 , the transmission mechanism 5 comprises a cam 51, a transmission gear set 52 and a transmission rack 531. The cam 51 is arranged at the end of the connecting end 411 of the handle 41 and can rotate around the rotating shaft 410 of the handle 41. The transmission gear set 52 comprises a first transmission gear 521 engaged with the cam 51 and a second transmission gear 522 engaged with the transmission rack 531. The first transmission gear 521 is engaged with the second transmission gear 522. The transmission rack 531 is connected with the first pressing part 21 and extends along the spacing direction of the first pressing part 21 and the second pressing part 22. Rotating the handle 41 can drive the transmission rack 531 to move back and forth along the length direction of the transmission rack 531. In this way, rotating the handle 41 drives the transmission gear set 52 through the cam 51 on the handle 41, and drives the transmission rack 531 through the transmission gear set 52 to realize the movement of the first pressing part 21, so that the handle 41 is transmitted to the first pressing part 21.

[0069] Further, the lower end of the first pressing member 21 is provided with a horizontally extending sliding base plate 53, and the left and right sides of the sliding base plate 53 are respectively provided with the transmission racks 531, and the sliding base plate 53 can move back and forth along the length direction of the transmission racks 531. The transmission mechanism 5 further comprises a gear base 54 arranged along the left and right direction, and the gear base 54 is respectively provided with an upper wheel shaft 541 and a lower wheel shaft 542 below the upper wheel shaft 541 along the left and right direction. The two ends of the upper wheel shaft 541 are respectively provided with the first transmission gears 521, and the two ends of the lower wheel shaft 542 are respectively provided with the second transmission gears 522. The two cams 51 are arranged along the left and right direction, and each cam 51 is engaged with the corresponding first transmission gear 521, and each transmission rack 531 is engaged with the corresponding second transmission gear 522. Through the above design, the first pressing member 21 can move back and forth along the direction of the distance between the first pressing member 21 and the second pressing member 22 more stably under the driving of the handle 41.

[0070] Preferably, the bottom surface of the gear base 54 is a plane and is matched with the top surface of the sliding base plate 53, and the bottom of the gear base 54 is provided with the rolling balls 55, which are at least partially exposed on the bottom surface of the gear base 54, and the lowest part of the rolling balls 55 is exposed below the bottom surface of the gear base 54. Through the design of the rolling balls 55, the friction between the bottom surface of the gear base 54 and the top surface of the sliding base plate 53 is reduced, the movement of the first pressing member 21 is smoother, the mutual friction between the parts is reduced, and the service life of the parts is prolonged. In the embodiment, the bottom surface of the gear base 54 is square, and the four corners of the bottom surface are respectively provided with the rolling balls 55, as shown in Figure 15 .
