Description

Technical Field

[0001] The utility model relates to the technical field of pressure roller processing, and more specifically, to a novel pressure-balanced pressure roller mechanism. Background Art

[0002] In modern industrial production, pressure roller mechanisms are widely used in printing, coating, papermaking, textiles, and other fields. Their primary function is to apply uniform pressure to the material through the roller, thereby achieving uniform coating, printing, or forming. However, traditional pressure roller mechanisms often have installation problems, resulting in equipment that cannot be replaced or repaired in a timely manner, a short service life, and reduced production efficiency. Furthermore, the operation is cumbersome. To address these issues, a new pressure-balanced pressure roller mechanism is proposed. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a new pressure-balanced pressure roller mechanism, through the mutual operation of the slide groove, slider, limit groove, auxiliary block, limit block, first spring, pull block, auxiliary groove, second spring and buffer sleeve, the outer pressure sleeve can use the limit block to disengage from the limit groove, and then the auxiliary block is fixed on the pressure roller rod by rotating the contact thread, and then the pressure roller rod and the outer pressure sleeve can be slidably connected and disengaged, so as to achieve stability during fixation and convenience during disassembly.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new type of pressure-balanced pressure roller mechanism, including a pressure roller rod, an outer pressure sleeve is inserted into the inner end of the pressure roller rod, a slide groove is opened inside the outer pressure sleeve, a slider is fixedly connected to the outer wall of the pressure roller rod, the slider is slidably connected inside the slide groove, a limiting groove is opened on the slider, an auxiliary block is threadedly provided on the pressure roller rod, a limiting block is slidably connected inside the auxiliary block, one end of the limiting block is inserted into the limiting groove, and a first spring is wound around the outer wall of the limiting block.

[0005] In a preferred embodiment, one end of the limiting block is fixedly connected to a pulling block, the pulling block is spherical, and the outer wall surface of the pulling block is provided with anti-slip lines.

[0006] In a preferred embodiment, one end of the first spring is fixedly connected to the pulling block, and the other end of the first spring is fixedly connected to the auxiliary block.

[0007] In a preferred embodiment, the auxiliary block, the limiting block, the first spring and the pulling block are symmetrically arranged on the pressure roller rod.

[0008] In a preferred embodiment, an auxiliary groove is provided inside the outer pressure sleeve, a second spring is provided at the temporal portion of the auxiliary groove, and buffer sleeves are provided at both ends of the second spring.

[0009] In a preferred embodiment, the outer wall of the buffer sleeve is fitted on the auxiliary groove.

[0010] The technical effects and advantages of this utility model are:

[0011] 1. The design of the outer wall of the buffer sleeve fitting on the auxiliary groove can significantly enhance the fixing effect of the second spring, preventing it from falling out of the auxiliary groove during operation. This design improves the tightness of the connection between the buffer sleeve and the auxiliary groove by increasing the contact area and friction, ensuring that the second spring will not be displaced or fall off when subjected to external force, thereby improving the overall stability and durability of the pressure roller mechanism. This not only reduces the failure rate of the equipment under high-intensity working conditions, but also extends its service life;

[0012] 2. This design allows the second spring to absorb some of the energy through elastic deformation when the pressure roller mechanism is impacted by external forces, thereby reducing the impact force on other parts of the equipment. The close-fitting design of the buffer sleeve effectively disperses the impact force on the outer pressure sleeve, allowing the entire pressure roller mechanism to maintain good performance and stability during long-term use. In this way, the equipment can operate under high-intensity and complex working conditions, reducing the frequency of maintenance and replacement, and improving production efficiency.

[0013] 3. The pressure roller mechanism realizes the convenience and stability of the disassembly and installation process through the interaction of the slide groove, slider, limit groove, auxiliary block, limit block, first spring, pull block, auxiliary groove, second spring and buffer sleeve. When the outer pressure sleeve needs to be removed, the elastic action of the pull block and the first spring enables the limit block to easily detach from the limit groove, thereby simplifying the disassembly process. When reinstalling, the auxiliary block and the pressure roller rod are connected by threading, and then the limit block is reinserted into the limit groove to achieve a stable connection. This design not only improves the efficiency of installation and disassembly, but also ensures the reliability of the equipment and the safety of operation.

[0014] 4. The auxiliary groove and buffer sleeve inside the outer pressure sleeve provide effective buffering protection for the outer pressure sleeve through the elastic action of the second spring. When the outer pressure sleeve is impacted, the second spring will undergo elastic deformation, and the buffer sleeve will fit tightly with the auxiliary groove to ensure that the second spring will not be separated from its fixed position. This design can not only effectively absorb impact energy and protect other parts of the equipment from damage, but also extend the overall service life of the pressure roller mechanism. Through this optimized design, the pressure roller mechanism can still maintain stable operation under various complex working conditions, providing more reliable equipment support for modern industrial production.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Refer to the instruction manual Figure 1-4 When the cam 1 is in the state of being moved, the cam 1 is in the state of being moved, and the cam 1 is in the state of being moved.

[0022] Then, one end of the limit block 7 is fixedly connected to a pull block 9, which is spherical and has anti-slip textures on its outer wall surface; this makes it easier to pull the limit block 7 outwards and has certain anti-slip properties.

[0023] Then, one end of the first spring 8 is fixedly connected to the pull block 9, and the other end of the first spring 8 is fixedly connected to the auxiliary block 6; driven by the elastic performance of the first spring 8, this structure enables the limit block 7 to be well inserted into the limit groove 5.

[0024] Next, the auxiliary block 6, the limit block 7, the first spring 8 and the pull block 9 are symmetrically arranged on the pressure roller rod 1; the setting of the two groups of auxiliary blocks 6 enables the two groups of limit blocks 7 to be inserted into the two groups of limit grooves 5, thereby achieving the effect of limiting and fixing and improving the stability of the device.

[0025] Next, an auxiliary groove 10 is opened inside the external pressure sleeve 2, a second spring 11 is provided at the temporal part of the auxiliary groove 10, and a buffer sleeve 12 is provided at both ends of the second spring 11; through this structure, when the external pressure sleeve 2 is impacted, it can be buffered to a certain extent by the second spring 11 to achieve the effect of ensuring the life of the equipment.

[0026] It should be noted that the outer wall of the buffer sleeve 12 is fitted on the auxiliary groove 10. Through this design, the fixing effect of the buffer sleeve 12 on the second spring 11 can be significantly improved, and the second spring 11 can be prevented from falling off from the auxiliary groove 10 during operation. In specific applications, when the outer pressure sleeve 2 is impacted by an external force, the second spring 11 will absorb part of the energy through its elastic deformation, thereby reducing the impact force on other parts of the equipment. This structural design ensures that the second spring 11 will not be displaced or fall off when subjected to impact by enhancing the friction and fit between the buffer sleeve 12 and the auxiliary groove 10, thereby improving the stability and durability of the entire pressure roller mechanism. In addition, the fitting design of the buffer sleeve 12 can also effectively disperse the impact force on the outer pressure sleeve 2, so that the pressure roller mechanism can maintain good performance and a long service life during long-term use.

[0027] The pressure roller mechanism achieves a dual improvement in stability and convenience through the interaction of the slide groove 3, slider 4, limiting groove 5, auxiliary block 6, limiting block 7, first spring 8, pulling block 9, auxiliary groove 10, second spring 11 and buffer sleeve 12. When the outer pressure sleeve 2 needs to be disassembled, it is only necessary to pull the limiting block 7 out of the limiting groove 5. This process is completed by the elastic action of the pulling block 9 and the first spring 8, ensuring the simplicity and safety of the disassembly process. When reinstalling, the auxiliary block 6 and the pressure roller rod 1 are threadedly connected, and then the limiting block 7 is reinserted into the limiting groove 5, so as to achieve a stable connection between the pressure roller rod 1 and the outer pressure sleeve 2. The close cooperation between the limiting block 7 and the limiting groove 5 not only improves the stability of the connection, but also maintains a good working condition under the action of external force, reducing the problem of loose connection caused by vibration or impact;

[0028] The auxiliary groove 10 and the buffer sleeve 12 opened inside the outer pressure sleeve 2 realize buffering protection for the outer pressure sleeve 2 through the elastic action of the second spring 11. The two ends of the second spring 11 are connected between the auxiliary groove 10 and the buffer sleeve 12. When the outer pressure sleeve 2 is impacted, the second spring 11 will undergo elastic deformation, and the buffer sleeve 12 will fit tightly with the auxiliary groove 10 to ensure that the second spring 11 will not be separated from its fixed position due to impact. This design can not only effectively absorb impact energy and protect other parts of the equipment from damage, but also extend the overall service life of the pressure roller mechanism. In addition, the close fit between the buffer sleeve 12 and the auxiliary groove 10 further enhances the impact resistance of the pressure roller mechanism, ensuring that it can maintain stable operation under various complex working conditions. In summary, the structural design of the buffer sleeve 12 and the auxiliary groove 10 significantly improves the stability and durability of the pressure roller mechanism by optimizing the fixing method of the elastic element, providing more reliable equipment support for modern industrial production.
