Description

Technical Field

[0001] This utility model relates to the field of transmission device technology, and in particular to an energy-saving transmission device for a fully automatic wire locking machine. Background Technology

[0002] A sewing machine is a device used for bookbinding. It primarily secures book pages together by stitching to form the spine. A transmission device transports the pages to the vicinity of the sewing machine's binding mechanism, pressing them between a conveyor belt and rollers. The rollers rotate rapidly, throwing the pages onto the binding mechanism, which then binds the pages into a book. Sewing is a traditional bookbinding method, offering advantages such as sturdiness, durability, and ease of reading. It is particularly suitable for binding high-quality printed materials such as hardcover books, picture albums, and manuals.

[0003] Chinese patent application CN202022773567.6 discloses an energy-saving transmission device for a fully automatic sewing machine. This device utilizes the magnetic attraction between the first and second soft magnetic strips to increase pressure, thereby increasing the friction between the conveyor belt and the rotating roller. Furthermore, during the rotation of the roller, the internal centrifugal ball maintains its original motion under centrifugal force, providing a force in the same direction as the central rotating rod, thus improving energy utilization. However, this device lacks an energy-saving mechanism at the rollers. The rollers must reach a certain speed to throw the pages near the binding mechanism, resulting in high energy consumption and hindering energy conservation and environmental protection.

[0029] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0030] Please see Figures 1 to 5This embodiment provides an energy-saving transmission device for a fully automatic wire locking machine, including: a main unit 1, which provides support for the transmission device;

[0031] Sewing part 2, which is located on one side of the top of the main unit 1, is used to bind the pages into a book.

[0032] The transmission mechanism 4 is located inside the main unit 1 and is used to transport the pages to be bound to the sewing unit 2.

[0033] The protection unit 3 is located above the transmission mechanism 4 and is fixedly connected to the host unit 1, and is used to isolate the transmission mechanism 4 from the outside world.

[0034] The throwing part 5 is located above the transmission mechanism 4. The throwing part 5 includes a first roller part 52 and a second roller part 53. The first roller part 52 and the second roller part 53 have the same structure. When the book page is located between the rotating first roller part 52 and the second roller part 53 and the moving conveyor belt 41, the first roller part 52 and the second roller part 53 deform and throw the book page to the binding part 2 for binding.

[0035] The main unit 1 includes a main body 11, a main platform 12 and a recess 13. The main platform 12 is fixedly disposed on the front side of the main body 11, and the recess 13 is disposed on the top of the main platform 12 for holding the transmission mechanism 4.

[0036] The sewing unit 2 includes a sewing platform 21, a stop bar 22, and a sewing machine 23. The sewing platform 21 is fixedly installed on the left side of the main body 12, and the sewing machine 23 is fixedly installed on the front side of the main body 11 for binding the pages. The stop bar 22 is fixedly installed on the top left side of the sewing platform 21 to prevent the pages from continuing to slide along the sewing platform 21.

[0037] The transmission mechanism 4 includes a conveyor belt 41, a drive roller 42, a driven roller 43, and a first motor 44. The drive roller 42 is located at one end of the groove 13 and is rotatably connected to the main platform 12. The driven roller 43 is located at the other end of the groove 13 and is rotatably connected to the main platform 12. The conveyor belt 41 is sleeved on the outer ring of the drive roller 42 and the driven roller 43. The first motor 44 is fixedly installed inside the main platform 12, and the output shaft of the first motor 44 is fixedly connected to one end of the drive roller 42.

[0038] The protective part 3 includes a protective shell 31 and a discharge port 32. The protective shell 31 is fixedly mounted on the top of the main unit 12 and located above the groove 13. The discharge port 32 is provided through the bottom left side of the protective shell 31 to provide a channel for the book pages.

[0039] The throwing unit 5 also includes a connecting shaft 51 and a second motor 54. The second motor 54 is fixedly mounted on the bottom of the front side of the main body 11. The output shaft of the second motor 54 is fixedly connected to the connecting shaft 51 and is used to drive the connecting shaft 51 to rotate.

[0040] The first roller section 52 includes a roller shaft 521 and several pressing sections 522. The roller shaft 521 is fixedly sleeved on the outer end of the connecting shaft 51, and the pressing sections 522 are all fixedly disposed on the outer ring of the roller shaft 521.

[0041] The tableting section 522 includes a connecting piece 523, a tableting body 524, and several tableting blade groups. Each tableting blade group includes tableting blades 525, several round pieces 526, and several column bars 527. The tableting body 524 is fixedly mounted on the outer ring of the roller shaft 521 via the connecting piece 523. The tableting blades 525 are all fixedly mounted on the outer side of the tableting body 524. The round pieces 526 are all fixedly mounted on the outer side of the tableting blades 525. The column bars 527 are arranged longitudinally between the round pieces 526 and are all fixedly connected to the tableting blades 525.

[0042] Both the disc 526 and the bar 527 are made of rubber, which increases the friction between the pressing blade 525 and the book page, making it easier for the pressing blade 525 to throw out the book page.

[0043] Both the pressing body 524 and the pressing blade 525 are made of beryllium copper alloy, which has good elasticity. After being squeezed and deformed, it can return to its original shape and release elastic energy to spring the book page toward the sewing platform 21. Both the pressing body 524 and the pressing blade 525 are arc-shaped, and their arc-shaped outer contour is the same as their rotation trajectory, which increases the contact area with the book page and makes it easier to throw the book page out.

[0044] After neatly stacking the pages to be bound in order, secure them with clips along opposite sides of the spine to prevent them from unraveling during transport and affecting the binding process. Place the stacked pages on top of the conveyor belt 41, start the first motor 44, which drives the drive roller 42 to rotate. The drive roller 42, through the conveyor belt 41, drives the driven roller 43 to rotate, transporting the pages on the conveyor belt 41 to the right side below the throwing section 5. Start the second motor 54, which drives the connecting shaft 51 to rotate. The connecting shaft 51 drives the first roller section 52 and the second roller section 53 to rotate. 3. The rollers rotate synchronously in a clockwise direction, pressing the pages at the bottom of the first roller 52 and the second roller 53. The linear speed of the first roller 52 and the second roller 53 rotating in a clockwise direction is the same as the speed at which the conveyor belt 41 moves to the left. When the pages are between the first roller 52, the second roller 53 and the conveyor belt 41, the pushing speed of the first roller 52 and the second roller 53 on the pages from above is the same as the pushing speed of the conveyor belt 41 on the pages from below. This prevents the pages from spreading out due to the different running speeds on the top and bottom sides, which would prevent the sewing machine from binding them. The first roller section 52, the second roller section 53, and the conveyor belt 41 together push the book pages toward the sewing section 2. After the pressing section 522 contacts the book page, it is squeezed by the upward reaction force of the book page. The pressing body 524 and the pressing blade 525 both bend toward the roller shaft 521, deform, and accumulate energy. When the pressing section 522 at the lowest end of the roller shaft 521 turns away from the book page, the pressing body 524 and the pressing blade 525 rebound, release energy, and throw the book page to the left onto the sewing platform 21. Under its inertia, the book page continues to slide to the left until it stops on the sewing platform 21 after one side abuts against the stop bar 22. The sewing machine 23 is operated to bind the book pages on the sewing platform 21. After binding is completed, the bound book is removed from the sewing platform 21 by manual or robotic arm, and the next layer of binding operation can continue. Because the tablet press body 524 and the tablet press blade 525 rebound and generate an additional leftward thrust on the book page, the book page can be thrown onto the thread-locking platform 21 even with a reduced rotational speed of the first roller part 52 and the second roller part 53. This reduces the energy input of the second motor 54, saves resources, and is beneficial to energy conservation and environmental protection.

[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
