Abstract

The present invention relates to the field of printing technology, and discloses a ribbon cutting machine for printing and binding, comprising a frame, a cutting assembly movably mounted at the bottom of the inner cavity of the frame, the cutting assembly comprising a guide plate slidably mounted around the inner cavity of the frame, a cutting plate movably engaged with the side wall of the guide plate, a storage assembly movably connected to the bottom of the frame, the storage assembly comprising a leveling bar movably arranged at the front and rear sides of the bottom of the frame, and storage tubes fixedly connected at both ends of the leveling bar. The present invention provides multiple sets of cutting plates, and the cutting assembly can simultaneously cut multiple sets of ribbon coils when in operation, greatly improving processing efficiency. After the cut ribbon falls into the storage drum, the cutting assembly synchronously drives the leveling bar, causing the storage drum to shake, so that the ribbons stacked in the storage drum are evenly spread out, avoiding single-point accumulation that causes the subsequent ribbon to be unable to fall normally after being cut. At the same time, the adjustment of the unwinding assembly is used to achieve control of different cutting lengths of the ribbon.

Description

Technical Field

[0001] The invention relates to the technical field of printing, in particular to a ribbon cutting machine for printing and binding. Background Art

[0002] Post-print binding refers to the binding process of printed sheets after printing. It is a process of connecting batches of scattered semi-finished pages of printed materials by different methods of binding, locking and gluing according to different specifications and requirements, and then selecting different binding methods for packaging and processing to make printed materials easy to use, read and store. In this process, ribbons can be used as bookmarks of printed materials, or for external decoration, bundling and other purposes of printed materials. Since printing and binding require a certain length of ribbon, it is necessary to cut the rolled ribbon. When the ribbon cutting machine for printing and binding in the prior art is used, one machine can only cut one roll of ribbon, resulting in low processing efficiency. Moreover, the cut ribbon falls directly into the collecting mechanism, and is easily accumulated in a certain place in the collecting mechanism, causing the accumulation height there to be too high, affecting the normal falling of the subsequently cut ribbon.

[0003] In addition, conventional cutting machines generally have a fixed cutting length for the ribbon, and are unable to achieve changes in the cutting length requirements for different ribbons. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems of low processing efficiency, single-point stacking of cut ribbons, and lack of controlled cutting of different lengths in the use of general ribbon cutting machines for printing and binding. The present invention provides a ribbon cutting machine for printing and binding.

[0005] In order to achieve the above-mentioned purpose, the present invention specifically adopts the following technical solutions:

[0006] The cam is connected to the bottom of the cam and is connected to the guide rail, and the cam is connected to the guide rail by a screw thread on the top of the cam and the screw rod is connected to the guide rail for movement.

[0007] Furthermore, a threaded gear rod is driven and installed in the middle of the inner cavity of the frame.

[0008] Furthermore, the cutting assembly also includes a rotating gear rotatably installed in the middle of the inner cavity of the frame, the rotating gear is meshed with the lower end of the threaded gear rod, and a hinge rod is movably connected between the eccentric part of the surface of the rotating gear and the guide plate.

[0009] Furthermore, two wedge grooves are formed on one side of the guide plate close to the cutting plate, and the side wall of the cutting plate includes a pin convex portion that is movably engaged in the wedge grooves.

[0010] Furthermore, the inner wall of the frame includes a cutting groove corresponding to the cutting plate, the cutting plate is slidably connected in the cutting groove, the cutting plate includes a tool on the side facing the cutting groove, and the movement direction of the cutting plate is perpendicular to the movement direction of the guide plate.

[0011] Furthermore, the storage component also includes a flexible connecting column fixedly connected to the front and rear sides of the bottom of the rack, the uniform swing bar is fixed at the bottom of the flexible connecting column, the surface of the hinge rod is movably connected with the swing bar, and a ball head rod is movably clamped between the swing bar and the uniform swing bar.

[0012] Furthermore, the right side of the swing bar includes a sliding groove that is movably engaged with the hinge rod.

[0013] Furthermore, the unwinding assembly also includes a conical gear rod rotatably installed on the front and rear sides of the inner cavity of the frame, the conical gear rod is meshed with the threaded gear rod, an adjusting screw is rotatably installed on the upper wall of the inner cavity of the frame, the adjusting screw is threadedly connected to the adjusting frame, and the upper wall of the frame is provided with a scale groove adapted to the top of the adjusting frame.

[0014] Furthermore, two sides of the adjustment frame are respectively provided with slots for movably engaging with the friction ring.

[0015] Furthermore, the roller rod is located on the upper side of the conical head gear rod, and one side of the roller rod connecting end is conical corresponding to the conical head gear rod, the distance between one side end of the roller rod connecting end and the end of the conical head gear rod is equal to the wall thickness of the friction ring, and the other end of the roller rod includes an end rod part for movable clamping of the ribbon coil.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention is provided with multiple sets of cutting plates, and multiple sets of ribbon coils can be cut at the same time when the cutting assembly is in operation, thereby greatly improving the processing efficiency. After the cut ribbons fall into the storage drum, the cutting assembly synchronously drives the swing bar to make the storage drum shake, and the ribbons stacked in the storage drum are evenly spread out, avoiding single-point accumulation that causes the subsequent ribbons to be unable to fall normally after being cut, and affects the normal collection function of the storage drum.

[0018] 2. In the present invention, when the threaded gear rod is in operation, the unwinding assembly is driven to automatically unwind the ribbon coiled material sleeved on the roller rod, and by moving the position of the adjustment frame, the input speed of the friction ring is changed. After the friction ring changes the contact position with the roller rod, the output speed of the roller rod is changed, thereby facilitating the control of cutting the ribbon into different lengths.

[0019] 3. The present invention utilizes the threaded gear rod to drive the cutting assembly and the unwinding assembly to be driven synchronously, thereby implementing the unwinding and cutting of multiple groups of ribbon coils, and the ribbon cutting is convenient and fast.

[0037] The effect achieved by the second embodiment is that the ribbon coils are cut at four sides of the machine respectively, and the cutting of the ribbon coils does not interfere with each other, thereby improving the cutting efficiency of the ribbon coils.

[0038] Example 3

[0039] See also Figure 2As shown, the storage assembly 4 also includes a flexible connecting column 41 fixedly connected to the front and rear sides of the bottom of the frame 1, a uniform swing bar 42 is fixed at the bottom of the flexible connecting column 41, a swing bar 45 is movably connected to the surface of the hinge rod 33, and a ball head rod 46 is movably clamped between the swing bar 45 and the uniform swing bar 42.

[0041] The effect achieved by the third embodiment is that the accumulated cut ribbons are shaken so that they are spread flat in the collecting mechanism, thereby avoiding single-point accumulation, which would cause the collecting height to be too high and affect the subsequent falling of the cut ribbons.

[0042] Example 4

[0043] See also Figure 4-6 As shown, the unwinding assembly 5 also includes a conical gear rod 51 rotatably mounted on the front and rear sides of the inner cavity of the frame 1. The conical gear rod 51 is meshed with the threaded gear rod 2. An adjusting screw rod 55 is rotatably mounted on the upper wall of the inner cavity of the frame 1. The adjusting screw rod 55 is threadedly connected to the adjusting frame 53. A scale groove adapted to the top of the adjusting frame 53 is opened on the upper wall of the frame 1.

[0044] Both sides of the adjustment frame 53 are respectively provided with slots for movably engaging with the friction ring 54 .

[0045] The roller rod 52 is located on the upper side of the conical gear rod 51, and one side of the connecting end of the roller rod 52 is conical corresponding to the conical gear rod 51. The distance between one end of the connecting end of the roller rod 52 and the end of the conical gear rod 51 is equal to the wall thickness of the friction ring 54. The other end of the roller rod 52 includes an end rod part for movable clamping of the ribbon coil.

[0046] The effect achieved by the fourth embodiment is: providing adjustment of the unwinding speed to achieve control to obtain the required ribbon cutting length, solving the problem that the cutting length of traditional equipment cannot be adjusted.

[0047] The working principle of the present invention is:

[0048] Before use, the ribbon coils are respectively sleeved on each roller rod 52, and according to the cutting length requirements, the adjusting screw 55 on the corresponding ribbon coil is rotated, and the scale groove adapted to the adjusting frame 53 is observed to control the movement of the adjusting frame 53 to drive the friction ring 54, and respectively change the contact position with the cone head gear rod 51 and the roller rod 52. This makes it possible that when the input speed of the threaded gear rod 2 driving the cone head gear rod 51 is fixed, the cutting speed of the cutting plate 34 is fixed, and the output speed of the roller rod 52 can be changed, that is, the speed of unwinding the ribbon is changed, thereby realizing the adjustment of the ribbon cutting length.

[0049] After each ribbon coil is installed and the corresponding cutting length of the ribbon coil is adjusted, the threaded gear rod 2 is driven to rotate, and the threaded gear rod 2 drives the cone-head gear rod 51 to rotate, and the friction ring 54 is used to frictionally transmit the transmission between the cone-head gear rod 51 and the roller rod 52, and the roller rod 52 drives the ribbon roll to be automatically unwound. Synchronously, the rotating gear 31 is driven to rotate by the engagement of the threaded gear rod 2, and the hinge rod 33 connected to the rotating gear 31 pushes and pulls the guide plates 32 on both sides respectively. Since two wedge grooves are provided on the side of the guide plate 32 close to the cutting plate 34, the side wall of the cutting plate 34 includes a pin convex part that is movably engaged in the wedge groove. When the guide plate 32 is pushed and pulled by the hinge rod 33, the cutting plate 34 uses its tool on the side facing the cutting groove to cut the ribbon lowered into the cutting groove.

[0050] At the same time, when the hinge rods 33 on both sides are offset, the swing bar 45 connected thereto moves in both the horizontal and vertical directions, and the swing bar 45 is used to pull and push the uniform swing bar 42. The storage tubes 44 at both ends of the uniform swing bar 42 are approximately oscillating in a circle, and the cut ribbons accumulated at a single point in the storage tube 44 are collapsed and flattened, avoiding single-point accumulation that causes the subsequent ribbons to be unable to fall normally after being cut.

[0051] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
