Description

Technical Field

[0001] This utility model relates to a feeding mechanism, and more particularly to a feeding mechanism for a perfect binding machine. Background Technology

[0002] In the perfect binding process of book production, a perfect binding machine is used to glue the pages together with hot melt adhesive. After the binding is completed, the book needs to be transported from the binding equipment to the cutting equipment. During the binding process, extrusion binding is usually used. After the binding is completed, the cover and inner pages are in an open state. After the binding is completed, the book needs to be transported to the cutting equipment. On the automated conveyor line, the book changes from a vertical state to a horizontal state for transportation.

[0003] In existing perfect binding machines, when a book moves vertically from the machine to the point where the clamping mechanism releases, allowing the book to pass vertically through a narrow, inclined guide chute, the cover and inner pages are closed by baffles on both sides. However, when the book comes into contact with the horizontal conveyor belt at the bottom of the inclined guide chute, it may jump or lag, resulting in slippage and poor conveying. Utility Model Content

[0004] The purpose of this utility model is to provide a feeding mechanism for a perfect binding machine, which solves the problem that when books come into contact with the horizontal conveyor belt at the bottom of the inclined guide chute in existing perfect binding machine feeding mechanisms, the books will jump or stagnate, resulting in slippage and poor conveying.

[0005] To address the aforementioned problems, this utility model provides a feeding mechanism for a perfect binding machine, comprising a guide trough that slopes downwards and is connected at its top to the perfect binding machine. The guide trough consists of a baffle and a bottom plate. A horizontal conveying platform is provided at the bottom of the guide trough, and a flexible, upward-sloping transition conveying section is rotatably connected to the front end of the conveying platform. The upward slope of the transition conveying section is consistent with the slope angle of the bottom plate of the guide trough. The transition conveying section is coplanar with the bottom plate. When the transition conveying section is under pressure, it rotates downwards to increase the angle between the transition conveying section and the conveying platform.

[0006] The feeding mechanism for a perfect binding machine provided by this utility model also has the following technical features:

[0007] Furthermore, the conveying platform includes a platform frame, with a support roller rotatably connected to the front end of the platform frame. The transition conveying section includes a connecting frame and end rollers. One end of the connecting frame is elastically rotatable with the support rollers, and the other end of the connecting frame is rotatably connected to the end rollers. The conveying platform and the transition conveying section also include an integral conveyor belt, which is fitted onto the end rollers and the platform frame.

[0008] Furthermore, torsion springs are fitted at both ends of the support roller. One end of the torsion spring is engaged with the connecting frame, and the other end of the torsion spring is engaged with the platform frame. A limiting rod for limiting excessive tilting of the connecting frame is fixedly connected to the platform frame.

[0009] Furthermore, a transition plate is fixedly connected to the base plate, and the bottom end of the transition plate contacts the conveyor belt.

[0010] Furthermore, a bending wheel is provided above the support roller, the bending wheel abuts against the conveyor belt, and a rotating axle is provided between the platform frame and the baffle, with the bending wheel fixedly connected to the axle.

[0011] Furthermore, a spine baffle is fixedly connected to one side of the platform frame, one end of the spine baffle is fixedly connected to the baffle of the guide chute, and the other end of the spine baffle is provided with an adjustment plate that tilts toward the conveying platform.

[0012] Furthermore, a vertical plate is fixedly connected to the other side of the platform frame, and a flexible push plate is hinged to the vertical plate.

[0013] Furthermore, an arc-shaped guide rod is fixedly connected to the back of the push plate, and a sliding hole is provided on the vertical plate for the guide rod to slide. A limit plate is fixedly connected to the end of the guide rod, and a spring is sleeved on the guide rod. The two ends of the spring abut against the vertical plate and the limit plate respectively.

[0014] The present invention has the following beneficial effects: The feeding mechanism for the binding machine described in this application utilizes an elastically inclined transition conveyor section. When the books slide down to the transition conveyor belt under the influence of gravity, the spine of the book and the transition conveyor section are converted into power conveying, which avoids jamming when the book is tilted to a flat surface. When the book spine leaves the bottom plate of the guide trough, the inclined transition conveyor section and the conveyor platform tend to be horizontal due to the influence of the weight of the book, making the book conveying more stable.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0022] like Figures 1 to 5 In the embodiment of the feeding mechanism for a perfect binding machine shown in this utility model, the feeding mechanism for a perfect binding machine includes a guide trough 1, which is inclined downwards. The top of the guide trough 1 is connected to the perfect binding machine. The guide trough 1 is composed of a baffle 2 and a bottom plate 3. A horizontal conveying platform 4 is provided at the bottom of the guide trough 1. A transition conveying section 5 that is elastically inclined upwards is rotatably connected to the front end of the conveying platform 4. The upward inclination angle of the transition conveying section 5 is consistent with the inclination angle of the bottom plate 3 of the guide trough 1. The transition conveying section 5 and the bottom plate 3 are coplanar. When the transition conveying section 5 is pressed, it rotates downwards to increase the angle between the transition conveying section 5 and the conveying platform 4.

[0023] Specifically, when the book's cover and inner pages, bound together, are clamped and conveyed to the guide trough 1, the book slides down from the guide trough 1 under the influence of gravity. The baffle 2 of the guide trough 1 holds the cover and inner pages together. When the book slides down to the transition conveyor section 5, the active conveying of the transition conveyor section 5 avoids the jamming that occurs when the inclined section turns to the horizontal section. When the book is conveyed forward until it leaves the bottom plate 3 and fully enters the transition conveyor section 5, the transition conveyor section 5 rotates downward under the pressure of the book and gradually becomes more horizontal with the conveyor platform 4, making the conveying smoother. When the book is completely conveyed away from the transition conveyor section 5, the transition conveyor section 5 returns to its inclined state and is coplanar with the bottom plate 3 under the action of elasticity. This device utilizes the elastically inclined transition conveyor section 5 to power the book when it slides down to the transition conveyor section 5 under the influence of gravity, avoiding jamming when the inclined section turns to the horizontal section. When the book is conveyed to the bottom plate 3 of the guide trough 1, the inclined transition conveyor section 5 becomes more horizontal with the conveyor platform 4 due to the influence of the book's gravity, making the book conveying smoother.

[0024] In one embodiment of this application, preferably, the conveying platform 4 includes a platform frame 6, with a support roller 7 rotatably connected to the front end of the platform frame 6. The transition conveying section 5 includes a connecting frame 8 and an end roller 9. One end of the connecting frame 8 is elastically rotatable with the support roller 7, and the other end of the connecting frame 8 is rotatably connected to the end roller 9. The conveying platform 5 and the transition conveying section 6 also include an integral conveyor belt 10, which is sleeved on the end roller 9 and the platform frame 6. This conveyor belt 10 is used to make the connecting frame 8 rotate around the support roller 7 when subjected to the pressure of books, thereby increasing the angle between the inclined and horizontal conveying surfaces and reducing the lag and book jumping when the inclined surface turns horizontal.

[0025] In one embodiment of this application, preferably, torsion springs 11 are sleeved at both ends of the support roller 7. One end of the torsion spring 11 is engaged with the connecting frame 8, and the other end of the torsion spring 11 is engaged with the platform frame 6. A limiting rod 12 is fixedly connected to the platform frame 6 to limit the excessive tilting of the connecting frame 8, so that the transition conveying section 5 remains tilted under a small pressure, and the transition conveying section 5 is driven to return to the tilted state when the books leave the transition conveying section 5.

[0026] In one embodiment of this application, preferably, a transition plate 13 is fixedly connected to the base plate 3, and the bottom end of the transition plate 13 contacts the conveyor belt 10, so as to effectively connect the gravity conveying section and the power conveying section of the base plate 3.

[0027] In one embodiment of this application, preferably, a bending wheel 14 is provided above the support roller 7, the bending wheel 14 abuts against the conveyor belt 10, and a rotating axle 15 is provided between the platform frame 6 and the baffle 2. The bending wheel 14 is fixedly connected to the axle 15 to ensure that the conveyor belt 10 always fits against the support roller 7, so as to prevent the conveyor belt 10 from becoming loose when the connecting frame 8 tilts and changes horizontally.

[0028] In one embodiment of this application, preferably, a spine baffle 16 is fixedly connected to one side of the platform frame 6, one end of the spine baffle 16 is fixedly connected to the baffle 2 of the guide trough 1, and the other end of the spine baffle 16 is provided with an adjustment plate 17 that tilts toward the conveying platform 4, which is used to push the books down and flatten them so that the books are changed from vertical conveying to horizontal conveying.

[0029] In one embodiment of this application, preferably, a vertical plate 18 is fixedly connected to the other side of the platform frame 6, and an elastic push plate 19 is hinged to the vertical plate 18. When the books are pushed over, the push plate 19 can correct the tilting of the books so that the spine of the books abuts against the spine baffle 16, thereby correcting the regularity of the book transport.

[0030] In one embodiment of this application, preferably, an arc-shaped guide rod 20 is fixedly connected to the back of the push plate 19, and a sliding hole (not shown in the figure) is provided on the vertical plate 18 for the guide rod 20 to slide. A limiting plate 21 is fixedly connected to the end of the guide rod 20, and a spring 22 is sleeved on the guide rod 20. The two ends of the spring 22 abut against the vertical plate 18 and the limiting plate 21 respectively, so as to make the push plate 19 generate elastic force to push the tilted book to correct its direction.

[0031] In summary, the feeding mechanism for the perfect binding machine in the above embodiments of this utility model specifically involves the book sliding down the guide trough 1 under gravity as the cover and inner pages, bound together, are clamped and conveyed to the guide trough 1. The baffle 2 of the guide trough 1 holds the cover and inner pages together. When the book slides onto the upward-sloping conveyor belt 10, the conveyor belt 10 provides the conveying power. The conveyor belt 10 conveys the book until it is fully within its range. Under the pressure of the book, the connecting frame 8 gradually becomes horizontal with the platform frame 6. The conveyor belt 10 continues to transport the book. To reduce the jamming during the transition between the inclined and horizontal sections, after the books enter the conveyor platform 4, the connecting frame 8 returns to the inclined position under the action of the torsion spring 11. When the books are conveyed to the conveyor platform 4, they are tilted and flattened by the push of the adjusting plate 17. When flattened, the spine of the books is pushed towards the spine baffle 16 by the push plate 19 to complete the adjustment. This device uses the movable transition conveyor section 5 to reduce the lag between the inclined and horizontal sections of the conveyor mechanism, making the conveying smoother. It also uses the adjusting plate 17 and the push plate 19 to solve the problem of books being scattered when they are switched from vertical to horizontal conveying.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
