Description

A track type hot stamping plate holder for tipping paper hot stamping machine which is convenient to replace

technical field

The utility model relates to the field of printing equipment, in particular to a rail-type hot stamping plate frame in tipping paper hot stamping equipment.

Background technique

With the continuous development of the printing market, most printing machinery factories are faced with the pressure of how to realize the rapid plate change system, and how to realize the rapid plate change system is a problem that printing producers must face. At present, most printing equipments use the technology of sleeve-type plate rollers to facilitate customers’ plate-changing operations, and sleeve-type plate-changing technology has become an important technical indicator to measure whether printing equipment is advanced.

For example, "201110410543 A Sleeve Roller Quick Change Mechanism for Flexographic Printing Machine", which discloses a sleeve plate roller quick change mechanism for flexographic printing One end of the roller mandrel is fixed on the movable door through a bearing, and a round hole with a diameter larger than the diameter of the sleeve plate roller is arranged on the wall board. The slider of the fixed support is provided with a guide shaft perpendicular to the wallboard on the upper fixed support, the movable door is arranged on the guide shaft and can move along the guide shaft, the lower end of the movable door is provided with a locking handle, and the side of the movable door is provided with The ball screw that can move the movable door, when the plate needs to be changed, first loosen the locking handle, pull the handle and pull it out along the direction of the guide shaft, so that the movable door is separated from the upper fixed support, and the movable door is separated from the mandrel of the plate roller , and then move the upper and lower fixed supports to the side through the motor and screw rod, then inflate the mandrel of the plate roller, pull out the sleeve printing plate, replace it with a new sleeve printing plate, return all parts to their original positions in turn, and complete change version.

Another example is "01228867.5 Sleeve Type Roller/Net Roll Replacement Device for Flexographic Printing Machine", which is equipped with an openable and openable wheel seat at the free end of the printing machine corresponding to the plate roll and screen roll. A lock groove is recessed on the bottom side of the wheel seat, and a fixed pin capable of moving up and down is set corresponding to the lock groove. The wheel can make the fixed pin protrude and snap into the lock groove for locking and positioning, so that the plate roll/net roll can be exposed quickly, and the sleeve of the plate roll/net roll can be replaced easily. When changing the sleeve of the plate roll or screen roll, turn and lock The handle makes the main wheel of the handle mesh with the gear part of the fixed pin to form a rotation. The rotation action forms an axial downward movement on the threaded part, so that one end of the fixed pin retracts into the first hole, so that the openable wheel seat can be disengaged and can be removed. Sleeve, after replacement, close the openable wheel base to the free end of the net roll, and then turn the locking handle in reverse, so that the main wheel of the handle meshes with the gear part of the transmission fixed pin to form a reverse rotation. The part is formed to move upward in the axial direction, so that one end of the fixing pin protrudes from the first hole and extends into the lock, so that the openable wheel base can be inserted into the mesh roll, and the positioning is locked by the locking device, thereby completing the plate change .

However, the above-mentioned sleeve plate changing technology is mainly applied to flexo plates, and for bronzing, because the working environment is high temperature, high pressure, and high speed, some bronzing plates made of flexible materials are not suitable for long-term work in this environment, and The hot stamping effect produced by the copper hot stamping plate is not only clear and beautiful, but also durable, so the hot stamping plate used in most hot stamping equipment is a hard belt shaft hot stamping plate made of copper. When installing the traditional belt-axle hot stamping plate, first install bearings on the shafts at both ends, then install sliders outside the bearings, and finally put the hot stamping plate with bearings and sliders into the chute of the hot stamping group as a whole; When replacing the hot stamping version, it is necessary to take out the whole hot stamping version with bearings and sliders, then remove the sliders and bearings in turn, and then install them again according to the installation procedure. It is inconvenient, inefficient, time-consuming and expensive to replace the hot stamping version. Workmanship, poor safety, inconvenient storage, poor flexibility, non-standardization and other shortcomings are not compatible with the development of modern printing, especially in large-scale hot stamping, it is even more difficult to replace large hot stamping plates.

In addition, due to the diversity of orders in actual production, the hot stamping plate is often replaced, and the bearing and shaft are often separated and combined. Every time the hot stamping plate is replaced, the bearing and slider on the original plate must be removed and installed on the newly replaced hot stamping plate. On the shaft, and the fit between the two is tight, which will affect the accuracy of the bronzing plate after long-term use.

Therefore, the development of a device that can quickly replace the shaft-type hot stamping plate will play a positive role in improving the efficiency and quality of hot stamping, and promoting the development of the hot stamping industry towards fast, light, safe, high-quality, high-safety, and high-standardization. .
