Description

Technical Field

[0001] This utility model relates to the field of printing press technology, specifically to a printing press with shock absorption function. Background Technology

[0002] In the modern printing industry, the printing press, as a core production piece of equipment, directly determines the precision and quality of printed materials through its operational stability. With the increasing demands for image clarity and registration accuracy in packaging printing, book printing, and other fields, the vibration problems generated during high-speed operation of the equipment are becoming increasingly prominent. During operation, the printing press generates periodic vibrations in multiple components, including motor drive, roller rotation, and paper transport. These vibrations not only cause defects such as ghosting and blurring in the printed images but can also lead to loosening of equipment parts, accelerated wear, and a shortened lifespan of the equipment.

[0003] Currently, traditional printing presses mostly rely on rubber pads on their bottom feet for vibration damping. This only provides preliminary buffering for low-frequency, small-amplitude vibrations. For high-frequency vibrations generated during high-speed operation or impact vibrations caused by sudden changes in local loads (such as uneven paper stacking), this single damping structure cannot effectively absorb energy, nor can it adapt to changes in local loads (such as increased pressure in paper stacking areas). This easily leads to vibrations being transmitted to the machine body, affecting printing accuracy. Furthermore, the contact area of ​​the feet on existing printing presses is limited. In workshop environments with slight bumps, depressions, or uneven surfaces, the feet cannot evenly distribute the weight of the equipment, easily causing the machine to tilt or sway, further exacerbating the vibration amplitude. Additionally, some printing presses use an integrated design for their auxiliary support structure, making disassembly and installation complex. When it is necessary to move the equipment or adjust the work position, the presence of support components increases the difficulty of operation. Therefore, a printing press with vibration damping capabilities is needed to solve the problems existing in current technology. Utility Model Content

[0004] The purpose of this invention is to provide a printing press with shock absorption function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a printing press with shock absorption function, comprising a printing press, wherein the bottom of the printing press is provided with leveling feet, and a reinforcing support mechanism is provided between two rows of leveling feet at the bottom of the printing press, the reinforcing support mechanism comprising a support pad and an inflatable support assembly, the support pad being provided at the bottom of the printing press, the inflatable support assembly being provided above the printing press, an anti-slip rubber pad being fixed at the bottom of the support pad, and mounting brackets being provided on both sides of the support pad.

[0006] Preferably, the inflatable support assembly includes a first cushioning airbag, a second cushioning airbag is provided on one side of the first cushioning airbag, and a third cushioning airbag is provided on the other side of the first cushioning airbag.

[0007] Preferably, connecting pipes are fixedly connected between the first and second buffer airbags and between the first and third buffer airbags, and an inflation nozzle is fixed to one end of the second buffer airbag.

[0008] Preferably, an adjusting screw is slidably connected in a slide rail inside the support pad, and an adjusting knob is threaded onto the surface of the adjusting screw.

[0009] Preferably, one end of the adjusting screw is fixed to the middle of one end face of the mounting bracket, and the mounting bracket is provided with a positioning groove on the side near the leveling foot.

[0010] Preferably, the bottom of the leveling foot is fixed with a shock-absorbing rubber pad, and the surface of the leveling foot is threaded with a fastening nut.

[0011] This utility model provides a printing press with shock absorption function, which has the following advantages compared with the prior art:

[0012] The leveling feet at the bottom of the printing press are equipped with shock-absorbing rubber pads, which directly buffer vibrations transmitted to the ground during machine operation. The inflatable support component in the reinforcement support mechanism, through the synergistic action of the first, second, and third buffer airbags, utilizes the compressibility of gas to further absorb vibration energy. The three airbags are connected by pipes, forming a uniform buffer support after inflation. This effectively mitigates vibrations caused by localized load changes due to paper stacking and other factors during printing press operation. Combined with the shock-absorbing rubber pads on the leveling feet, multi-layered shock absorption is achieved, effectively reducing the risk of displacement or tilting caused by machine vibration and swaying, providing a stable foundation for high-precision printing operations. The inflatable support component can be easily inflated and deflated via an inflation nozzle, allowing for adjustments to the support strength according to actual usage needs. The overall structural design balances ease of use with functional flexibility.

[0013] The support pad, in conjunction with the additional brackets on both sides, significantly increases the contact area of ​​the leveling feet. In scenarios with uneven ground, the larger contact area can distribute localized pressure and reduce machine instability caused by ground bumps or depressions. The reinforcement support mechanism is installed by adding the support pad and additional brackets directly into the middle area of ​​the bottom of the printing press. The disassembly process is equally simple and efficient, and disassembly will not affect the normal handling and operation of the printing press. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a printing press with shock absorption function. The printing press includes a printing press 1, and a leveling support 2 is provided at the bottom of the printing press 1. A shock-absorbing rubber pad 3 is fixed to the bottom of the leveling support 2, and a fastening nut is threaded onto the surface. This design not only helps to absorb shock, but also ensures the stability of the leveling support 2 after height adjustment through the fastening nut. A reinforcing support mechanism 4 is provided at the bottom of the printing press 1 between the two rows of leveling support 2. The reinforcing support mechanism 4 includes a support plate 5 and an inflatable support assembly 11. The support plate 5 is located at the bottom of the printing press 1, and an anti-slip rubber pad 10 is fixed to its bottom to enhance the friction with the ground and reduce slippage. A mounting bracket 6 is provided on both sides of the support plate 5.

[0021] Furthermore, the structure of the inflatable support assembly 11 deserves specific explanation. It includes a first buffer airbag 12, a second buffer airbag 13 on one side of the first buffer airbag 12, and a third buffer airbag 14 on the other side. Connecting pipes 15 are fixedly connected between the first and second buffer airbags 12 and 13, and between the first and third buffer airbags 12 and 14. An inflation nozzle 16 is fixed to one end of the second buffer airbag 13. Inflation can be applied to the three buffer airbags through the inflation nozzle 16. The connecting pipes 15 ensure gas flow between the airbags, resulting in more uniform inflation and consistent cushioning effect. The fully inflated airbags support the support pad 5 and the bottom of the printing press, improving the situation where a large area of ​​the printing press bottom is suspended. The airbags can adjust their support strength through inflation pressure, using gas compression to buffer vibration. This is particularly suitable for scenarios where localized load changes occur due to paper stacking, improving shock absorption without altering the force balance of the main support.

[0022] Furthermore, an adjusting screw 7 is slidably connected in the slide rail inside the support plate 5, and an adjusting knob 8 is threaded onto the surface of the adjusting screw 7. One end of the adjusting screw 7 is fixed to the middle of one end face of the mounting bracket 6, and a positioning groove 9 is provided on the side of the mounting bracket 6 near the leveling foot 2. This structure facilitates the adjustment of the mounting bracket 6 according to the position of the leveling foot 2, and the positioning groove 9 allows the mounting bracket 6 to more accurately mate with the leveling foot 2; the support plate 5 and the mounting bracket 6 are assembled on the two rows of leveling feet 2. The combination of the two increases the contact area with the ground, which can reduce displacement or tilting caused by vibration and shaking during the operation of the printing press, making it suitable for high-precision printing presses; in scenarios with uneven ground, it can disperse local pressure, reduce the probability of machine instability, and the mounting method is convenient for disassembly and does not affect the handling of the printing press.

[0023] This solution includes the following workflow:

[0024] Before use, the printing press 1 is placed on the ground using the leveling feet 2. Adjusting the height of the leveling feet 2 allows the printing press 1 to be stably supported on the ground.

[0025] Before installing the reinforcement support mechanism 4, first insert the support pad 5 and the two mounting brackets 6 from the middle area of ​​the bottom of the printing machine 1. Then, place the two mounting brackets 6 close to the corresponding two rows of leveling feet 2. Then, rotate the adjustment knob 8 along the adjustment screw 7 so that the adjustment knob 8 is pressed against the side surface of the support pad 5. This allows the support pad 5 and the mounting brackets 6 to be assembled on the two rows of leveling feet 2. The support pad 5 and the mounting brackets 6 together can increase the contact area of ​​the two rows of leveling feet 2, which can reduce displacement or tilting caused by vibration and shaking during the operation of the printing machine. This is especially suitable for high-precision equipment such as printing machines. In scenarios where the ground is not flat, a larger contact area can distribute local pressure and reduce the probability of machine instability during operation due to ground protrusions or depressions. In addition, the support pad 5 is installed in an additive manner, which facilitates subsequent disassembly, and the disassembly does not affect the convenient handling of the printing machine.

[0026] After the support pad 5 is installed on the printing press, air is injected into the first buffer airbag 12, the second buffer airbag 13, and the third buffer airbag 14 through the air inlet 16. The first buffer airbag 12, the second buffer airbag 13, and the third buffer airbag 14, when fully inflated, support the support pad 5 and the bottom of the printing press. In this way, the inflatable support assembly 11 and the support pad 5 work together to improve the large-area suspension of the bottom of the printing press. The airbags can adjust the support force through inflation pressure and can buffer vibration through gas compression. It is especially suitable for scenarios where the weight of the suspended part is unstable (such as local load changes caused by paper stacking). The inflatable support assembly 11 can improve the shock absorption effect without changing the force balance of the main support and only buffering local vibration.
