Description

Technical Field

[0001] This utility model relates to the field of coil book manufacturing technology, and in particular to a single-coil bookbinding mechanism with automatic waste discharge capability. Background Technology

[0002] In existing plastic single coil binding equipment, such as the plastic single coil binding equipment disclosed in the applicant's previous patent application CN222246625U, the plastic single coil is positioned by three drive rollers (i.e. pressure rollers 21) and driven to rotate forward and move, and then bound to the booklet.

[0003] However, this binding method has certain inconveniences. When the equipment malfunctions or there is residual material in the equipment, the machine needs to be stopped and the plastic single coils that have not been fully threaded into the booklet need to be removed manually. Since the machine needs to be stopped during the waste removal process, the waste removal efficiency is low, which affects the normal production progress.

[0004] In addition, since three drive rollers are used to position the plastic single coil, if the position of the coil is misaligned with the position of the hole in the booklet, the positions of the three drive rollers need to be adjusted repeatedly, which takes a long time and therefore the adjustment efficiency is low.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0039] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0040] Furthermore, the use of terms such as "first" and "second" in this utility model is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0041] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] like Figure 1-2 As shown, the single-coil bookbinding mechanism with automatic waste discharge in this embodiment includes a base 10, a support beam 20, an upper positioning component 30, a lower positioning component 40, a feeding guide rail 50, a book pressing component 60, a binding roller 70, a first motor 80, a binding guide head 90, a guide head adjusting component 100, a coil driving component 110, and a coil cutting component 120.

[0043] The upper positioning component 30 and the lower positioning component 40 are respectively arranged on the upper and lower sides of the feeding guide rail 50, and a coil conveying channel is formed between them. The feeding guide rail 50 is used to support the book to be bound. The binding production line conveys the book along the feeding guide rail 50 to the space between the upper positioning component 30 and the lower positioning component 40.

[0044] The pressing assembly 60 is mounted on the upper side of the feeding guide rail 50 via the support beam 20. The pressing assembly 60 includes a fourth cylinder 61 and a book pressing plate 62. The fourth cylinder 61 is fixed on the support beam 20, and the book pressing plate 62 is located at the end of the piston rod of the fourth cylinder 61. The support beam 20 is also provided with a second proximity switch 63. The second proximity switch 63 can be a photoelectric switch, an infrared sensor switch, a capacitive switch, or other inductive switches.

[0045] When the second proximity switch 63 senses that the book has been delivered to the correct position, the fourth cylinder 61 drives the book pressure plate 62 to press down, clamping the book between the feeding guide rail 50 and the book pressure plate 62.

[0046] The binding roller 70 is located on one side of the coil conveying channel. The first motor 80 is connected to the binding roller 70 by a drive, and the two can be connected by a drive assembly such as a pulley, sprocket or gear.

[0047] A second fixed plate 71 is provided on one side of the binding roller 70. A second movable plate 72 and a fifth cylinder 73 are provided on the second fixed plate 71. The second movable plate 72 is slidably connected to the second fixed plate 71 through a fifth slide rail assembly 74. The fifth cylinder 73 is fixed on the second fixed plate 71 and its piston rod end is throttle connected to the second movable plate 72. A second support rod 75 is provided on the side of the second movable plate 72 near the binding roller 70. The two ends of the second support rod 75 are rotatably connected to the binding roller 70 through bearing seats 76.

[0048] The fifth cylinder 73 drives the second movable plate 72 and the second support rod 74 to move closer to the coil conveying channel, thereby bringing the binding roller 70 into contact with the coil. The binding roller 70 has two flat portions 77 symmetrically arranged along its axial direction on its circumferential surface. When the first motor 80 drives the binding roller 70 to rotate, because the binding roller 70 is not a complete circle, an eccentric striking effect is generated during rotation, thus simultaneously conveying and striking the coil, making the coil more smoothly bound into the coil hole on the booklet.

[0049] like Figure 3 As shown, the upper positioning component 30 includes an upper fixed plate 31, an upper pressure plate 32, and an upper positioning cylinder 33. The upper pressure plate 31 is slidably connected to the upper fixed plate 31 through the first slide rail assembly 34. The upper positioning cylinder 33 is fixedly mounted on the upper fixed plate 31 and is connected to the upper pressure plate 32 in a transmission manner. The bottom of the upper pressure plate 32 is provided with an upper coil positioning groove 35.

[0050] The lower positioning assembly 40 includes a lower fixed plate 41, a lower pressure plate 42, and a lower positioning cylinder 43. The lower pressure plate 43 is slidably connected to the lower fixed plate 41 through the second slide rail assembly 44. The lower positioning cylinder 43 is fixedly mounted on the lower fixed plate 41 and is connected to the lower pressure plate 42 in a transmission manner. The lower pressure plate 42 has a lower coil positioning groove 45 on its top.

[0051] The upper positioning cylinder 33 drives the upper pressure plate 32 and the lower positioning cylinder 43 drives the lower pressure plate 42 to move closer to each other. Under the drive of the binding roller 70, the coil moves forward in a spiral manner along the coil conveying channel formed by the upper coil positioning groove 35 and the lower coil positioning groove 45. The binding hole on the book is also located in the coil conveying channel, so that the binding of the book is completed during the spiral conveying of the coil.

[0052] Since the coil is limited by the upper pressure plate 32, the lower pressure plate 42 and the binding roller 70, and all three are movable, it is relatively easy to adjust even if the coil is misaligned with the binding hole. The position of the coil and the binding hole can be adjusted in a short time by adjusting the position of the upper pressure plate 32, the lower pressure plate 42 or the binding roller 70, resulting in high operating efficiency.

[0053] like Figure 4As shown, the binding guide head 90 is located at the end of the coil conveying channel, and the guide head adjustment assembly 100 is connected to the guide head 90 in a transmission manner.

[0054] The guide head adjustment assembly 100 includes a first fixed plate 101, a first movable plate 102, a first cylinder 103, and a guide head mounting plate 104. The first cylinder 103 is fixedly mounted on the first fixed plate 101. The first movable plate 102 is slidably connected to the first fixed plate 101 through a third slide rail assembly 105. The piston rod of the first cylinder 103 is drively connected to the first movable plate 102. The guide head mounting plate 104 is located on the top of the first movable plate 102. The mounting guide head 90 is fixedly mounted on the guide head mounting plate 104.

[0055] The first cylinder 103 can drive the first movable plate 102 to reciprocate along the first fixed plate 101, thereby driving the guide head mounting plate 104 and the binding guide head 90 to move closer to or away from the end of the coil conveying channel.

[0056] The coil drive assembly 110 is located on one side of the binding guide head 90. The coil drive assembly 110 includes a second cylinder 111, a mounting frame 112, a second motor 113, and a drive roller 114. The second cylinder 111 is fixedly mounted on the first movable plate 102. The mounting frame 112 is slidably connected to the first fixed plate 101 through the fourth slide rail assembly 115. The piston rod of the second cylinder 111 is drivenly connected to the fourth slide rail assembly 115 through the mounting frame 112. The second motor 113 is drivenly connected to the drive roller 114, and both are mounted on the mounting frame 112. The second motor 113 and the drive roller 114 can be connected by common transmission methods such as pulleys, sprockets, or gears.

[0057] The second cylinder 111 can drive the second motor 113 and the drive roller 114 to approach or move away from the binding guide head 90. When the drive roller 114 approaches the binding guide head 90, it contacts the coil surface and the coil is driven forward by the friction between the drive roller 114 and the coil.

[0058] like Figure 5 As shown, a first support rod 106 is provided on the first fixed plate 101. A rotating block 108 is provided on the first support rod 106 via a bearing 107. A detection rod 109 is provided through the rotating block 108 on one side of the bearing 107. One end of the detection rod 109 extends to one side of the binding guide head 90, and a first proximity switch 1010 is provided above the other end. The first proximity switch 1010 is connected to the first support rod 106 via a connecting plate 1011. The first proximity switch 1010 can be an inductive switch such as a photoelectric switch, an infrared sensor switch, or a capacitive switch.

[0059] After the entire coil is inserted into the book, one end of the detection rod 109 will naturally droop under the action of gravity and press on the surface of the binding guide head 90. At this time, the other end of the detection rod 109 will approach the first proximity switch 1010. The system then determines that the binding is complete. At this time, the second cylinder 111 and the fifth cylinder 73 will drive the drive roller 114 and the binding roller 70 to reset respectively.

[0060] like Figure 6-7 As shown, a coil cutting assembly 120 is provided at the end of the coil conveying channel near the binding guide head 90. The coil cutting assembly 120 includes a third cylinder 121, scissors 122, scissor seat 123, and tension spring 124. The third cylinder 121 is located above the binding guide head 90. The scissors 122 are rotatably mounted at the end of the upper pressure plate 32 via the scissor seat 123. One end of the tension spring 124 is connected to the upper part of the scissors 122, and the other end is connected to the tension spring positioning block 125. The tension spring positioning block 125 and the third cylinder 121 are both fixed on the support beam 20. The piston rod end of the third cylinder 121 is provided with a pressure block 126 that is connected to the upper part of the scissors 122.

[0061] When the binding time exceeds the system's preset time (i.e., the detection rod 109 still detects the presence of the coil within the preset time), the system will determine that there is an abnormality in the binding process and it needs to be handled. At this time, the third cylinder 121 is activated, pushing the scissors 122 to swing around the scissor seat 123. Under the action of the lever, the blade at the lower end of the scissors 122 will move closer to the side of the sharp edge of the upper coil positioning groove 35, and the coil will be cut off by the shearing action of the two.

[0062] Subsequently, the first cylinder 103 actuates, causing the guide head adjustment assembly 100 to move downward as a whole, leaving sufficient space for material discharge. Then, the second motor 113 drives the drive roller 114 to rotate, rotating and conveying the coils that remain on the binding guide head 90 that have not been inserted into the book, thereby realizing the automatic waste discharge function. Since this process does not require machine shutdown and manual handling, it reduces the workload of the staff and avoids unnecessary time waste, thus effectively improving the binding efficiency of coil books.

[0063] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
