Description

Technical Field

[0001] The present invention relates to the technical field of bookbinding machines, and in particular to a bookbinding machine and method for controlling glue application at the glue head and glue tail. Background Art

[0002] The emergence of desktop bookbinding machines enables users to easily produce exquisite contract books, meeting manuals, briefing materials, operation manuals, tender documents, insurance policies, and personalized notebooks in the unit. It has the advantages of small size, fast preheating, low power consumption, fast binding, high glue-binding thickness limit, and simple operation, replacing traditional plastic clip strips. A bookbinding machine generally includes a paper milling mechanism, a glue application mechanism, and a cover packaging device. Before glue binding, the paper milling mechanism is first used to mill the edges of the paper to be glue-bound, leaving a large number of grooves on the paper edges for easy glue application. After paper milling, the paper edge slides over the paper milling mechanism, so that the glue adheres to the paper edge. Finally, the cover is attached to the glued paper through the cover packaging device to complete the glue binding. However, in the process of glue-binding the paper by the existing bookbinding machines, since the glue application wheel in the glue pool is always rotating, when the paper touches and leaves the glue application wheel, too much glue will be applied to the head and tail of the paper, thus affecting the subsequent glue-binding work and unable to meet the actual needs. Summary of the Invention

[0003] The purpose of the present invention is to solve the above-mentioned drawbacks existing in the prior art, and to provide a bookbinding machine and method for controlling glue application at the glue head and glue tail.

[0004] To achieve the above purpose, the present invention adopts the following technical solutions:

[0005] Design a bookbinding machine and method for controlling glue application at the glue head and glue tail, including a bookbinding machine body, a glue pool provided on the bookbinding machine body, two glue application wheels spaced in the glue pool, a glue scraping assembly on one side of the glue application wheel, and further including

[0006] Swinging assemblies, there are two of them, respectively arranged on one side of the glue scraping assembly. Among them, the glue scraping assembly includes a rotating shaft and a glue scraping plate connected to the rotating shaft, and the swinging assembly is connected to one end of the rotating shaft;

[0007] Linkage assembly, which is used to connect the power assembly and the swinging assembly. The power assembly drives the linkage assembly to act according to the movement trajectory of the paper, so that the swinging assembly pushes the rotating shaft to rotate and drives the glue scraping plate to approach or move away from the glue application wheel.

[0008] Further, the swinging assembly includes a mounting block, a through hole penetrating the mounting block for the rotating shaft to pass through, a deformation groove penetrating the top of the mounting block and communicating with the through hole, and a locking bolt for adjusting the width of the deformation groove.

[0009] Further, the linkage assembly includes a push-pull plate, a first support shaft disposed at the bottom of the mounting block and rotatably connected to one end of the push-pull plate, and a crank arm rotatably connected to the other end of the push-pull plate through a second support shaft.

[0010] Further, the power assembly includes a motor fixedly connected to the end of the crank arm away from the second support shaft, and a mounting plate for fixing the motor on the bookbinding machine body.

[0011] Further, the swing assembly further includes a fixed sleeve disposed on one side of the mounting block close to the mounting plate, a limiting rod screwed to the fixed sleeve, and a blocking plate disposed on the mounting plate corresponding to the limiting rod.

[0012] Further, a pair of photoelectric sensors are provided on the bookbinding machine body.

[0013] A method for controlling the gluing of the head and tail of the book uses the above bookbinding machine, and includes the following steps.

[0014] Step 1, using the photoelectric sensor to detect the running state of the head of the book. After the head of the book passes the photoelectric sensor, the photoelectric sensor transmits a glue head fine-tuning pulse signal to the controller of the bookbinding machine.

[0015] Step 2, after the controller receives the glue head fine-tuning pulse signal, it controls the power assembly to drive the linkage assembly to act, so that the swing assembly pushes the rotating shaft to rotate and drives the scraping plate away from the gluing wheel.

[0016] Step 3, using the photoelectric sensor to detect the running state of the tail of the book. After the tail of the book passes the photoelectric sensor, the photoelectric sensor transmits a glue tail fine-tuning pulse signal to the controller of the bookbinding machine.

[0017] Step 4, after the controller receives the glue head fine-tuning pulse signal, it controls the power assembly to drive the linkage assembly to act, so that the swing assembly pushes the rotating shaft to rotate and drives the scraping plate close to the gluing wheel.

[0018] The bookbinding machine and method for controlling the gluing of the head and tail of the book proposed by the present invention have the beneficial effects that:

[0019] By setting the swing assembly, the linkage assembly and the power assembly, the present invention can control the scraping assembly to approach or move away from the gluing wheel according to the movement track of the paper. Before the paper contacts the gluing wheel and after leaving the gluing wheel, the scraping plate can approach the gluing wheel and quickly scrape the gluing wheel. After the paper is above the gluing wheel, the scraping plate moves away from the gluing wheel, and the gluing wheel is used to glue the paper, avoiding excessive glue on the head and tail of the paper and improving the bookbinding effect on the paper.

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] Embodiment, referring to Figures 1-3 , a bookbinding machine and method for controlling the application of glue to the head and tail of the glue, including a bookbinding machine body 1, a glue pool 2 provided on the bookbinding machine body 1, two glue application wheels 3 spaced apart in the glue pool 2, a glue scraping assembly 4 located on one side of the glue application wheels 3, and further including

[0025] A swing assembly 5, the number of which is two, is respectively arranged on one side of the glue scraping assembly 4. Among them, the glue scraping assembly 4 includes a rotating shaft 401 whose two ends are respectively rotatably connected to the bookbinding machine body 1, and a glue scraping plate 402 connected to the rotating shaft 401. The swing assembly 5 is connected to one end of the rotating shaft 401;

[0026] A linkage assembly 6, which is used to connect the power assembly 7 and the swing assembly 5. The power assembly 7 drives the linkage assembly 6 to act according to the movement track of the paper, so that the swing assembly 5 pushes the rotating shaft 401 to rotate and drives the glue scraping plate 402 to approach or move away from the glue application wheels 3. Preferably, a sensor for detecting the movement of the paper can be provided on the bookbinding machine body 1 in this embodiment. When the paper is above the glue application wheels 3, the controller receives the sensor signal and controls the power assembly 7 to act.

[0027] By setting the swing assembly 5, the linkage assembly 6 and the power assembly 7, the present invention can control the glue scraping assembly 4 to approach or move away from the glue application wheels 3 according to the movement track of the paper. Before the paper contacts the glue application wheels 3 and after leaving the glue application wheels 3, the glue scraping plate 402 can approach the glue application wheels 3 and quickly scrape the glue application wheels 3. After the paper is above the glue application wheels 3, the glue scraping plate 402 moves away from the glue application wheels 3, and the glue application wheels 3 are used to apply glue to the paper, avoiding excessive glue being applied to the head and tail of the paper and improving the bookbinding effect on the paper.

[0028] In an alternative embodiment of the present invention, the swing assembly 5 includes a mounting block 501, a through hole 502 penetrating the mounting block 501 for the rotation shaft 401 to pass through, a deformation groove 503 penetrating the top of the mounting block 501 and communicating with the through hole 502, and a locking bolt 504 for adjusting the width of the deformation groove 503. In this embodiment, by rotating the locking bolt 504, the width of the deformation groove 503 is reduced, thereby driving the inner wall of the through hole 502 to squeeze the rotation shaft 401 to achieve the fixation of the rotation shaft 401.

[0029] In an alternative embodiment of the present invention, the linkage assembly 6 includes a push-pull plate 601, a first support shaft 602 provided at the bottom of the mounting block 501 and rotatably connected to one end of the push-pull plate 601, and a crank arm 604 rotatably connected to the other end of the push-pull plate 601 through a second support shaft 603.

[0030] In an alternative embodiment of the present invention, the power assembly 7 includes a motor 701 fixedly connected to the end of the crank arm 604 away from the second support shaft 603, and a mounting plate 702 for fixing the motor 701 on the bookbinding machine body 1. Preferably, the motor 701 in this embodiment can be implemented by a stepper motor; the crank arm 604 rotates under the drive of the motor 701 and drives the push-pull plate 601, so that the mounting block 501 pushes the rotation shaft 401 to rotate, thereby controlling the scraping plate 402 to approach or move away from the glue application wheel 3.

[0031] In an alternative embodiment of the present invention, the swing assembly 5 further includes a fixed sleeve 505 provided on one side of the mounting block 501 close to the mounting plate 702, a limiting rod 506 screwed to the fixed sleeve 505, and a blocking plate 507 provided on the mounting plate 702 corresponding to the limiting rod 506. By the limiting rod 506 abutting against the blocking plate 507, the mounting block 501 can be blocked and limited to prevent the swing angle of the mounting block 501 from being too large.

[0032] In an alternative embodiment of the present invention, a pair of photoelectric sensors are provided on the bookbinding machine body 1.

[0033] A method for controlling the glue application at the head and tail of the glue, using the above-mentioned bookbinding machine, includes the following steps.

[0034] Step 1, using the photoelectric sensor to detect the running state of the head of the book. When the head of the book passes the photoelectric sensor, the photoelectric sensor emits a glue head fine-tuning pulse signal to the controller of the bookbinding machine.

[0035] Step 2: After the controller receives the glue head fine-tuning pulse signal, it controls the power assembly 7 to drive the linkage assembly 6 to act, so that the swing assembly 5 pushes the rotating shaft 401 to rotate and drives the glue scraping plate 402 away from the glue applying wheel 3. Such an operation can avoid applying too much glue when the head of the book touches the glue applying wheel 3, and improve the effect of gluing the head of the book.

[0036] Step 3: Use the photoelectric sensor to detect the running state of the tail of the book. After the tail of the book passes the photoelectric sensor, the photoelectric sensor emits a glue tail fine-tuning pulse signal to the controller of the bookbinding machine.

[0037] Step 4: After the controller receives the glue head fine-tuning pulse signal, it controls the power assembly 7 to drive the linkage assembly 6 to act, so that the swing assembly 5 pushes the rotating shaft 401 to rotate and drives the glue scraping plate 402 close to the glue applying wheel 3. Such an operation can avoid applying too much glue when the tail of the book leaves the glue applying wheel 3, and improve the effect of gluing the tail of the book.
