Description

Technical Field

[0001] This invention relates to perfect binding machines, and more particularly to a perfect binding machine for office desktops. Background Technology

[0002] Existing book binding machines include utility model patents such as "Fully Automatic Binding Machine Device" (application number 99208422.9), "New Type of Binding Machine" (application number 201920553107.7), and "A New Type of Energy-Saving Binding Machine" (application number 202023035677.9), as well as the authorized publication number CN 102815110, which was developed and put into production by the inventor of this application in earlier years. B's invention patent "Spray-on Glue Wireless Binding Machine" and the recently developed and put into production invention application No. 201910183093.9 "A Pneumatic Cold Glue Bookbinding Device," all these book binding machines have their inner page clamping device, spine gluing device, and cover gluing device arranged in a row from left to right. When binding books, the inner pages to be bound must be clamped by the inner page clamping device at one end of the binding machine and then moved to the glue box in the middle of the binding machine for gluing. Then, they are moved from the middle of the binding machine to the other end to seal the cover. After binding is completed, the inner page clamping device... The binding machine needs to be returned to its initial position. Even if some book binding machines have some structural changes, such as rotating 180 degrees from the center position to apply glue, these traditional binding machines still have the following major drawbacks: the binding machine is long and bulky, requiring a lot of office space; the overall structure is not compact; it uses a lot of metal materials in its manufacture, resulting in high costs; the reciprocating motion during binding is long, resulting in high energy consumption; the noise generated by friction and vibration during the movement is also high; the binding accuracy and quality are difficult to further improve; and it is impossible to achieve mass production and automated industrial mass production. Summary of the Invention

[0003] The purpose of this invention is to provide an office desktop binding machine with a compact overall structure. The machine body is only about one-third the length of a traditional binding machine of the same type. It is small in size, occupies little office space, uses less metal material in its manufacture, and has low cost. The reciprocating motion stroke during binding is short, resulting in low energy consumption. The noise generated during operation is greatly reduced due to the absence of sliding friction and vibration. The binding accuracy and quality are further improved. It is particularly suitable for various office spaces, has a high cost-performance ratio, and can realize mass production and automated industrial mass production.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An office desktop perfect binding machine includes a frame, an inner page holder for clamping the inner pages of a book to be bound, a glue box for applying glue to the spine of the book to be bound, and a clamping platform for attaching the cover. The inner page holder is located on the upper part of the frame. The machine is characterized in that: the clamping platform is located on the lower part of the frame; the glue box is located between the inner page holder and the clamping platform; the glue box is equipped with a glue box driving device for reciprocating along the spine direction; and the clamping platform is equipped with a clamping platform lifting device for raising and lowering it. When the glue box needs to move along the spine direction to apply glue to the spine or to reset, the clamping platform lifting device drives the clamping platform to a position below the glue box so that the glue box passes over it; when the clamping platform needs to rise to attach the cover or fall to reset, the glue box driving device drives the glue box to move to the outside of the clamping platform so that the clamping platform passes beside it.

[0006] The glue box includes a glue wheel disposed in the glue groove. The glue box driving device includes a chain three driven by a walking motor. The chain three is connected to the glue box through a connecting structure. When the walking motor drives the chain three to move forward or backward through the sprocket, the chain three drives the glue box to move to the left or right along the spine direction through the connecting structure.

[0007] The glue box driving device further includes: fixed frames at the front and rear ends of the glue box, slide rail grooves on the front and rear sides of the lower part of the inner page holder, a rack on the lower rear side of the inner page holder, and a glue wheel driving gear that meshes with the rack at the rear end of the glue box. Rollers extending into the corresponding slide rail grooves are provided on the upright plates of the two fixed frames.

[0008] The connection structure includes a chain connecting plate and a pressure plate for connecting chain three, which are set on the rear fixed frame upright plate.

[0009] The clamping platform includes a rear clamping plate, a front clamping plate, and a clamping base plate. The rear clamping plate is driven by two rear clamping forks located at both ends of the rear clamping drive shaft, and the front clamping plate is driven by two front clamping forks located at both ends of the front clamping drive shaft. The clamping motor drives the two rear clamping forks and the two front clamping forks through a gear transmission mechanism.

[0010] The clamping platform lifting device includes two lifting wall plates passing through both ends of the rear clamping drive shaft and both ends of the front clamping drive shaft. The upper end of the left lifting wall plate is fixedly connected to the left end of the clamping base plate, and the upper end of the right lifting wall plate is fixedly connected to the right end of the clamping base plate. The outer side of the left lifting wall plate is connected to the lifting chain set on the left fixed wall plate through a connecting plate, and the outer side of the right lifting wall plate is connected to the lifting chain set on the right fixed wall plate through a connecting plate. When the drive shaft driven by the turbine synchronous motor rotates, the drive shaft drives the corresponding lifting chain to move through the lifting sprockets set at its front and rear ends, thereby driving the two lifting wall plates to rise or fall synchronously.

[0011] Both of the aforementioned lifting wall panels are equipped with a guiding mechanism consisting of a lifting guide rod and a lifting slider.

[0012] In the initial state of the above technical solutions, the clamping platform is located at the bottom of the frame, and the glue box is located to the left of the inner page holder and the clamping platform. When it is necessary to glue the book to be bound, the control device drives the clamping platform to rise to the preset top position through the clamping platform driving device. When the inner pages of the book to be bound are placed in the inner page holder, the clamping base plate of the clamping platform also serves as a support to support the spine of the book to be bound. When the control device controls the inner page holder to clamp the book to be bound, the control device controls the clamping platform to descend to the bottom position, and then through the... The glue box drive device controls the glue box to move to the right. When the glue box moves to the preset right limit position, the control device controls it to move to the left and reset. During the leftward movement of the glue box, the glue wheel rotates to apply glue to the spine of the book above it. After the glue box is reset, the control device drives the clamp with the cover placed on it to rise through the clamp drive device. When the top of the clamp touches the spine of the book, it stops rising. The control device controls it to clamp the book to be bound, and the cover is glued. Finally, the control device controls the clamp to release and reset, and at the same time controls the inner page holder to release, so as to complete the book binding.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: Due to the adoption of the above technical solution, the clamping platform is located at the lower part of the frame, the glue box is located between the inner page holder and the clamping platform, the glue box is equipped with a glue box driving device that drives it to reciprocate along the spine direction, and the clamping platform is equipped with a clamping platform lifting device that drives it to rise and fall. When the glue box needs to move along the spine to apply glue to the spine or to reset, the clamping platform lifting device drives the clamping platform to a position below the glue box so that the glue box passes over it; when the clamping platform needs to rise to glue the cover or fall to reset, the glue box driving device drives the glue box to move to the outside of the clamping platform so that the clamping platform passes beside it. This top-to-bottom arrangement of the inner page holder, glue box, and clamping platform breaks through the traditional left-to-right arrangement of existing perfect binding machines, resulting in a compact overall structure. With a body length only about one-third that of a traditional perfect binding machine, it is small in size and occupies little office space, making it particularly suitable for various space-constrained office environments. Due to its compact overall structure and small size, less metal material is used in its manufacture, resulting in significantly reduced costs and high cost-effectiveness. This top-down design sets the traditional reciprocating inner page holder in a fixed position, while the immobile glue box moves back and forth. The clamping table also serves as the book-setting table. During perfect binding, the movement length of the glue box is only about one-third that of a traditional perfect binding machine. The reciprocating motion stroke is short, resulting in low energy consumption. In particular, the operator no longer needs to run back and forth with the inner page holder (loading inner pages on the left and running to the right to load the cover), greatly improving work efficiency and enabling mass production and automated industrial mass production.

[0014] A further beneficial effect is that the plastic box is driven by the chain three to move left or right along the spine of the book. During operation, there is no sliding friction or vibration, and the noise generated is greatly reduced, making it more suitable for use in quiet office spaces.

[0015] A further beneficial effect is that the glue box driving device also includes fixed frames at the front and rear ends of the glue box, slide rail grooves on the front and rear sides of the lower part of the inner page holder, a rack on the lower rear side of the inner page holder, and a glue wheel driving gear at the rear end of the glue box that meshes with the rack. Rollers extending into the corresponding slide rail grooves are provided on the upright plates of both fixed frames. With this structure, the glue wheel is driven to rotate by the glue wheel driving gear, and the glue box body does not need to be equipped with a power device. The structure is very compact and small, further reducing the overall length and volume of the binding machine. The use of gear transmission and rollers makes the reciprocating movement of the glue box very smooth, and the binding accuracy and quality are further improved.

[0016] A further beneficial effect is that the lifting of the clamping platform is driven by two lifting wall plates through the rear clamping drive shaft and the front clamping drive shaft passing through its holes. The two lifting wall plates also serve as the fixing components of the clamping base plate. The structure is compact and has very few parts, which further reduces the overall length and volume of the binding machine, further saves the metal materials used in manufacturing, and further reduces the cost.

[0017] Using a single drive shaft, the lifting chains are driven by lifting sprockets located at its front and rear ends to move, thereby raising or lowering two lifting wall panels. This structure ensures that the two lifting wall panels rise and fall synchronously, improving the accuracy and quality of adhesive application.

[0018] This desktop binding machine breaks through the limitations of existing binding machine layouts and operating methods. Its compact structure and length (approximately one-third the size of traditional binding machines of the same type, meaning books of roughly the same size) result in a small footprint, requiring less office space. It uses less metal material, leading to lower costs. The short reciprocating motion during binding reduces energy consumption, and the absence of sliding friction and vibration significantly reduces noise. This further improves binding accuracy and quality, making it particularly suitable for various office environments where books are less than 2cm thick. It offers high cost-effectiveness and enables mass production and automated industrial mass production. Attached Figure Description

Figures 1 to 17 This invention will be described in detail below. It should be understood that the specific embodiments described in this specification are merely for explaining the invention and are not intended to limit the scope of protection of the invention.

[0039] This invention relates to an office desktop perfect binding machine, comprising a frame 1, an inner page holder 2 for clamping the inner pages of a book to be bound, a glue box 3 for applying glue to the spine of the book to be bound, and a clamping platform 4 for attaching the cover. The inner page holder 2 is located on the upper part of the frame 1. The clamping platform 4 is located on the lower part of the frame 1. The glue box 3 is located between the inner page holder 2 and the clamping platform 4. The glue box 3 is equipped with a glue box driving device that drives it to reciprocate along the spine direction. The clamping platform 4 is equipped with a clamping platform lifting device that drives it to rise and fall. When the glue box 3 needs to move along the spine direction to apply glue to the spine or to reset, the clamping platform lifting device drives the clamping platform 4 to a position below the glue box 3 so that the glue box 3 passes over it. When the clamping platform 4 needs to rise to attach the cover or fall to reset, the glue box driving device drives the glue box 3 to move to the outside of the clamping platform 4 so that the clamping platform 4 passes to its side.

When the motor 2-09 drives the chain 2-19 to move forward or backward via the sprocket 2-22, the chain 2-19 drives the glue box 3 to move left or right along the spine direction via the connecting structure. The glue box driving device also includes fixed... The fixed frame 3-13 includes slide rail grooves 2-20 on the front and rear sides of the lower part of the inner page holder 2, a rack 2-21 on the lower rear side of the inner page holder 2, and a rubber wheel drive gear 3-12 on the rear end of the glue box 3 that meshes with the rack 2-21.

The rubber wheel shaft 3-03 is supported on the rubber shaft sleeves 3-04 at both ends of the rubber groove 3-01. High-temperature deep groove ball bearings 3-05 are installed inside the rubber shaft sleeves 3-04. O-rings 3-06 are provided at both ends of the rubber wheel shaft 3-03 to prevent glue leakage. A one-way needle roller bearing 3-15 is provided between the rubber wheel drive gear 3-12 and the rubber wheel shaft 3-03. When the glue box 3 starts to move to the right, the glue wheel 3-02 does not rotate. When the glue box 3 moves to the right and returns, the glue wheel 3-02 rotates to start applying glue. The bottom of the glue box 3 is equipped with a heating mica sheet 3-07, a mica sheet pressure plate 3-08, and a temperature measuring wire fixing nut 3-09. The upper part of the glue box 3 is equipped with an adjusting plate 3-14. The roller 3-16 is set on the upright plate of the fixed frame 3-13 through a pin 3-17. The range of reciprocating movement of the glue box 3 is limited by the corresponding limit switch.

[0041] The clamping platform 4 includes a rear clamping plate 4-01, a front clamping plate 4-01', and a clamping base plate 4-18.

The drive and clamping motor 4-13 drives two rear clamping forks 4-03 and two front clamping forks 4-03' through a gear transmission mechanism; the clamping platform lifting device includes two lifting wall plates 4-08 passing through both ends of the rear clamping drive shaft 4-12 and the front clamping drive shaft 4-12', the upper end of the left lifting wall plate 4-08 is fixedly connected to the left end of the clamping base plate 4-18, the upper end of the right lifting wall plate 4-08 is fixedly connected to the right end of the clamping base plate 4-18, and the outer side of the left lifting wall plate 4-08 is connected to the fixed wall plate 4 on the left side through a connecting plate 4-07. The lifting chain 4-24 on the -21 is connected, and the outer side of the right lifting wall plate 4-08 is connected to the lifting chain 4-24 on the right fixed wall plate 4-21 through the connecting plate 4-07. When the drive shaft 4-23 driven by the turbine synchronous motor 4-10 rotates, the drive shaft 4-23 drives the corresponding lifting chain 4-24 to move through the lifting sprockets 4-19 set at its front and rear ends, so as to drive the two lifting wall plates 4-08 to rise or fall synchronously. Both of the lifting wall plates 4-08 are provided with a guide mechanism consisting of a lifting guide rod 4-04 and a lifting slider 4-06. Preferably, the lifting wall panel 4-08 is connected to the lifting slider 4-06 via the lifting slider fixing plate 4-05, the lifting guide rod 4-04 is mounted on the lifting guide rod fixing seat 4-09, the rear clamping plate 4-01 and the front clamping plate 4-01' are slidably mounted on the clamping base plate 4-18 via corresponding clamping plate sliders 4-16, the clamping motor 4-13 is fixed on the clamping motor fixing plate 4-17, the fixed wall panel 4-21 is mounted on the fixed wall panel mounting bracket 4-22, and the turbine synchronous motor 4-10 is mounted on the fixed base plate 4-11. A sensor 4 for detecting the lifting position of the clamping platform 4 is also provided on the fixed base plate 4-11. -15, the gear transmission mechanism includes a gear mounted on the shaft of the clamping motor 4-13, a gear mounted on the rear clamping transmission shaft 4-12 that meshes with the gear on the shaft of the clamping motor 4-13, a rear clamping gear 4-14 mounted on the rear clamping transmission shaft 4-12, and a front clamping gear 4-14' mounted on the front clamping transmission shaft 4-12'. The rear clamping gear 4-14, through meshing with the front clamping transmission shaft 4-12', drives the front clamping transmission shaft 4-12' and the rear clamping transmission shaft 4-12 to rotate synchronously in opposite directions. A photoelectric sensor 4-25 for sensing the cover to be glued is provided on the clamping base plate 4-18.

[0042] The inner page holder 2, apart from being equipped with the walking motor 2-09, chain three 2-19, sprocket 2-22, slide rail groove 2-20, and rack 2-21, has a structure that is basically the same as the prior art. It also includes: a cover 2-01, a main body 2-02, a front clamping cardboard 2-03, a rear clamping cardboard 2-04, a photoelectric plate 2-07, a paper clamping motor 2-10, a first sprocket 2-13, a first lead screw 2-14, a second lead screw 2-15, a lead screw nut 2-16, a first chain 2-17, a second chain 2-18, and a transmission sprocket 2-23. The paper clamping motor 2-10 operates, which drives the lead screw 2-15 and lead rod 2-14 through the transmission of sprocket 2-13, chain 2-18 and chain 2-17. The reciprocating motion of the lead screw nut 2-16 realizes the clamping and loosening of the front clamping paperboard 2-03 and the rear clamping paperboard 2-04.

[0043] In the initial state, the clamping platform 4 is located at the bottom of the frame 1, and the glue box 3 is located to the left of the inner page holder 2 and the clamping platform 4;

[0044] When it is necessary to bind the book, the control device drives the clamping platform 4 to the preset top position through the clamping platform drive device. When the inner pages of the book to be bound are placed in the inner page holder 2, the clamping base plate 4-18 of the clamping platform 4 also serves as a base to support the spine of the book to be bound.

[0045] When the control device controls the inner page holder 2 to clamp the book to be bound, the control device controls the clamping platform 4 to descend to the bottom position, and then controls the glue box 3 to move to the right through the glue box drive device. When the glue box 3 moves to the preset right limit position, the control device controls it to move to the left to reset. During the leftward movement of the glue box 3, the glue wheel 3-02 rotates to apply glue to the spine of the book above it.

[0046] After the glue box 3 is reset, the control device drives the clamping platform 4, which has the cover on it, to rise through the clamping platform drive device. When the top of the clamping platform 4 touches the spine of the book, it stops rising. The control device controls it to clamp the book to be bound, and the cover is glued. Finally, the control device controls the clamping platform 4 to release and reset, and at the same time controls the inner page holder 2 to release, so as to complete the book binding.

[0047] This office desktop binding machine breaks through the limitations of existing binding machine layouts and operating methods. It has a compact structure, with a body length only about one-third that of traditional binding machines of the same type. It is small in size, occupies little office space, uses less metal material in its manufacture, and has low cost. The reciprocating motion stroke during binding is short, resulting in low energy consumption. The noise generated during operation is greatly reduced due to the absence of sliding friction and vibration. The binding accuracy and quality are further improved. It is especially suitable for various office environments where the thickness of the bound books is less than 2cm. It has a high cost performance and can realize mass production and automated industrial mass production.
