Description

Technical Field

[0001] The invention relates to the technical field of plastic film production, and in particular to a roller pressing device for plastic film production with an anti-adhesion function. Background Art

[0002] During the preparation of plastic film, the film will adhere to the surface of the roller press due to the effects of high temperature and high pressure, resulting in reduced film quality, reduced production efficiency and even equipment damage. The roller press with anti-adhesion function can reduce the adhesion between the film and the roller press through special surface coating or material selection, thereby avoiding the occurrence of adhesion problems. The roller press with anti-adhesion function can reduce the friction and adhesion between the film and the roller press, making it easier to separate the film during the rolling process and reducing resistance in the production process.

[0003] Compared with the existing technology that uses coating on the outer wall of the round roller to solve the adhesion problem, as time goes by and the frequency of use increases, the coating will gradually wear and lose its original anti-adhesion effect. In particular, when the roller pressing device is subjected to a high pressure and high temperature working environment, the coating will wear more rapidly. In addition, some coating materials contain harmful substances, and during the roller pressing process, harmful waste will be generated due to high temperature and high pressure. In addition, the coating needs to be re-coated after wear or peeling, which will increase the maintenance cost and downtime of the equipment;

[0004] When the driven roller is in use for a long time or under heavy pressure, fatigue, thermal expansion or uneven load distribution of its own material will cause its own shape to change. For example, wear and deformation of the cylinder body will affect the parallelism between the driven roller and the active roller. The parallelism between the driven roller and the active roller is lost, resulting in uneven indentation, different depths, position offset and other problems. This seriously affects the indentation effect and quality of the product, especially for packaging or printing products that require precise indentation, which directly leads to product failure or scrapping. In addition, due to the indentation quality problem, it is necessary to increase the inspection and repair process, or even re-perform the indentation operation, which not only increases the production cost, but also leads to the shutdown of the production line and the decline of production efficiency.

[0005] In view of this, the present invention proposes a rolling device for producing plastic films with an anti-adhesion function to compensate for and improve the deficiencies of the prior art. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a rolling device for producing plastic films with an anti-adhesion function to solve the technical problems raised in the above background technology.

[0011] Furthermore, the liquid storage cylinder and the injection tube both initially store water-based lubricant, the liquid storage cylinder is made of a transparent material as a whole, and the interior of the liquid storage cylinder is connected to a liquid refilling tube.

[0012] Furthermore, the partition plate as a whole divides the interior of the injection tube into two equidistant parts, the through-axis is located in the upper half of the interior of the injection tube, and the delivery hose is located in the lower half of the injection tube.

[0013] Furthermore, the through shaft and the extrusion plate form a ball screw structure, and the extrusion plate is initially located at one end close to the transmission assembly, the lower surface of the extrusion plate is symmetrically fixedly connected with a universal ball, and the partition plate is provided with an arc groove at the position corresponding to the universal ball, and the extrusion plate and the partition plate are slidably connected through the universal ball and the arc groove.

[0014] Furthermore, the transmission assembly as a whole is composed of a linkage wheel, a driven wheel and a transmission belt combination. The linkage wheel in the transmission assembly is symmetrically fixedly connected to both sides of the driven pressure roller, and the driven wheel is symmetrically fixedly connected to one end of the through-axis that is away from each other, and the axial length size of the linkage wheel and the driven wheel in the transmission assembly is 1:4.

[0015] Furthermore, the end of the scraper plate away from the patch shell tends to fit the uppermost end of the outer wall of the driven pressure roller, the end of the scraper plate away from the patch shell is curved, and the end of the scraper plate close to the patch shell is inclined straight.

[0016] Furthermore, the traction balancing mechanism includes a buckle ring symmetrically fixedly connected to the outer wall of the driven pressure roller, and an elastic curved rod is installed inside the buckle ring. Both ends of the elastic curved rod are hinged with a hinge group, and one end of the hinge group close to each other is hinged with a sliding shaft, and the sliding shaft is fixedly connected to the buckle, and a pointer is installed on the upper end of the sliding shaft. The outer wall of the sliding shaft is sleeved with a limiting cylinder, and the limiting cylinder is fixedly connected to the upper surface of the equipment bracket as a whole.

[0017] Furthermore, the hinge group is composed of a combination of no less than four rectangular plates, with two rectangular plates forming a group, and the ends of each group of hinged plates close to each other are rotatably connected through a convex shaft, and each rectangular plate is generally wide in the middle and narrow at both ends.

[0018] Furthermore, a cylindrical protrusion is fixedly connected to the outer wall of the sliding shaft, a bending groove is opened on the inner wall of the limiting cylinder at a position corresponding to the cylindrical protrusion, and the sliding shaft and the limiting cylinder are slidably connected through the cylindrical protrusion and the bending groove.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present device realizes a fast, efficient, stable and automatic lubrication process through the linkage cooperation between a few structures, effectively avoiding the adhesion of the driven pressure roller during the rolling process, and at the same time improves other defects of the driven pressure roller during operation. The present device first realizes efficient power transmission through the transmission connection between the transmission components. This design ensures that the entire lubrication system can respond and start quickly when the driven pressure roller starts to rotate. Secondly, through the reciprocating movement of the through-shaft, it ensures that the lubricant can be automatically output and injected and replenished according to the change of air pressure caused by the change of the internal space of the injection tube. The lubricant forms a dynamic circulation inside the injection tube, ensuring that the outer wall of the driven pressure roller always maintains a proper amount of lubricating film. This dynamic lubrication method is more effective than static coating and can continuously provide lubrication, thereby ensuring the continuous supply of lubricant, reducing the need for manual intervention in the operation of the entire device. The lubricant is also stirred by the continuous rotation of the stirring wheel, avoiding the self-precipitation of the lubricant inside the liquid storage cylinder or the injection tube, ensuring the uniformity and effectiveness of the lubricant. Finally, the transparent design of the liquid storage cylinder allows the staff to visually observe the remaining amount of lubricant inside, and timely discover and replenish the lubricant to ensure that the device is always in the best working condition.

[0020] Since the driven pressure roller is in a high pressure and high temperature working environment when in use, compared with the prior art method of coating the outer wall of the driven pressure roller, the present device uses dynamic circulation of lubricant to ensure that the outer wall of the driven pressure roller always maintains a layer of appropriate lubricating film. This method not only solves the defect of the prior art coating method that gradually wears out with the passage of time and the increase in frequency of use, but also avoids the problem that some coating materials contain harmful substances and produce harmful waste due to high temperature and high pressure during the roller pressing process. At the same time, compared with the prior art, the present device greatly reduces the maintenance cost and downtime of the equipment operation through the process of automatically injecting supplementary lubricant into the injection tube. In addition, the lubricant can be automatically extracted and replaced according to the different materials of the film to be processed, thereby improving the compatibility and adaptability of the overall device;

[0021] The present device forms a sliding connection between the extrusion plate and the partition plate through a universal ball and an arc groove. This connection structure converts the traditional surface contact and line contact into point contact, so that the structure can tolerate the deviation between the connecting parts to a certain extent during movement, which helps to reduce assembly errors. Secondly, the sliding connection in the arc groove can reduce the friction resistance of the universal ball during movement, which is conducive to reducing the wear of the connection and extending the service life. Finally, according to the characteristics of the smooth outer wall of the universal ball and the small contact area with other parts, it can absorb vibration and impact to a certain extent during movement, which helps to reduce the vibration transmitted to other parts and improve the stability and comfort of the equipment.

[0022] The device designs the shaft length of the linkage wheel and the driven wheel in the transmission assembly to be 1:4. The linkage wheel with a small shaft length is used as a driving component. Since it has a small mass and moment of inertia, it can be accelerated and decelerated more easily, and then the driven wheel is driven to rotate through its own rapid response, so that the entire device can run quickly. According to the design of the shaft length of the two, the driven wheel rotates one circle when the linkage wheel rotates four circles. Since the rotation speed of the linkage wheel is relatively fast, the device limits the rotation speed of the driven wheel by limiting the transmission ratio, thereby avoiding the situation where the driven wheel rotates too fast and causes excessive output of lubricant, thereby ensuring that the lubricant is input in an appropriate amount to maintain a stable lubrication state of the system.

[0023] (2) The device enables the scraper plate component to automatically scrape off plastic raw material impurities or dust particles in the working environment remaining on the outer wall of the driven pressure roller when the driven pressure roller is performing the rolling process. This automatic cleaning function effectively reduces the impact of impurities on the rolling process and improves work efficiency and product quality. In addition, according to the shape of the scraper plate as a whole, which is first bent and then inclined in a straight line, the scraped impurities can slide down smoothly along the inclined part, thereby avoiding the problem of blockage of the curved part of the scraper plate due to long-term treatment of impurities. This ensures the continuous and stable operation of the equipment and reduces the maintenance cost and downtime caused by blockage. In addition, by removing the storage residue in combination with the above-mentioned spray lubricant, the lubrication state of the outer wall of the driven pressure roller can be maintained while removing impurities, thereby improving the rolling effect and product quality, thereby reducing the heat and particles generated by the friction of the outer wall of the driven pressure roller due to contact with impurities, and reducing the probability of deformation and wear of the driven pressure roller;

[0024] (3) This device aims to prevent the driven roller from being unbalanced through a series of sophisticated structural designs and balanced force, and to provide an early warning when an unbalance trend occurs. First, through the traction of the articulated group, this device can actively offset the tendency of the driven roller to be slightly unbalanced due to wear and fatigue. Even if the cylinder of the driven roller is partially worn and deformed, the support and traction of the articulated group can maintain its stability to a certain extent to prevent its position from being excessively shifted, thereby reducing the risk of failure caused by component imbalance. In addition, through the traction of the articulated group and the rotational downward movement of the sliding shaft, this device can optimize the force distribution of the components inside the balancing mechanism, making the force between the components more uniform, reducing the wear or damage caused by excessive local force, thereby extending the service life of each component and improving the reliability and durability of the entire system.

[0025] In addition, when the driven pressure roller shows an unbalanced trend, the device can provide timely warning through the rotation of the pointer. As the hinge group moves downward, the tip positions of the pointers will correspond to each other, thereby forming an obvious visual signal. Compared with the prior art that uses tools to test or visually touch the equipment when it is shut down, the warning method in the device is intuitive and easy to observe, so that the staff can quickly identify the unbalanced state of the driven pressure roller, so as to take adjustment measures in time to prevent the problem from further deteriorating. In addition, the device can perform real-time monitoring without stopping the machine, avoiding time delays and efficiency losses caused by tools to test the equipment when it is shut down.

[0026] The hinge group is composed of no less than four rectangular plates, and each rectangular plate is wide in the middle and narrow at both ends. The rectangular plate design of the hinge group that is wide in the middle and narrow at both ends enables the structure to disperse pressure more effectively when subjected to stress. The wide part can withstand greater pressure, while the narrow part provides the necessary flexibility to adapt to possible deformations. This design enhances the strength and stability of the entire structure, enabling it to better withstand external loads and internal stresses. Moreover, since the rectangular plates are combined and have a specific shape distribution, they can work together to optimize stress distribution. This distribution helps to reduce stress concentration, thereby reducing the risk of damage to the structure due to local overload. BRIEF DESCRIPTION OF THE DRAWINGS

The delivery hose 28 is connected with a patch shell 29, and the upper end of the patch shell 29 is fixedly connected with a scraper plate 210. The liquid storage cylinder 21 and the injection tube 22 are initially stored with water-based lubricants. The liquid storage cylinder 21 is made of a transparent material as a whole, and the interior of the liquid storage cylinder 21 is connected with a liquid refilling tube. The partition plate 23 divides the interior of the injection tube 22 into upper and lower parts at equal distances. The through shaft 24 is located in the upper half of the injection tube 22. 28 is located at the lower half of the injection tube 22, and the liquid storage cylinder 21 and the delivery hose 28 are both installed with a one-way valve. The through shaft 24 and the extrusion plate 26 form a ball screw structure, and the extrusion plate 26 is initially located at one end close to the transmission component 25. The lower surface of the extrusion plate 26 is symmetrically fixedly connected with a universal ball. The partition plate 23 is provided with an arc groove at the position corresponding to the universal ball. The extrusion plate 26 and the partition plate 23 are slidably connected through the universal ball and the arc groove. The transmission component 25 is composed of a linkage wheel, a pulley, and a pulley. The driving wheel and the transmission belt are combined, the linkage wheels in the transmission assembly 25 are symmetrically fixedly connected to the two sides of the driven pressure roller 14, the driven wheel is symmetrically fixedly connected to the ends of the through-shaft 24 that are away from each other, and the shaft length of the linkage wheel and the driven wheel in the transmission assembly 25 is 1:4, the end of the scraper plate 210 away from the patch shell 29 tends to fit the uppermost end of the outer wall of the driven pressure roller 14, the end of the scraper plate 210 away from the patch shell 29 is curved, and the end of the scraper plate 210 close to the patch shell 29 is inclined straight;

[0046] Specifically, through the reciprocating movement of the through-shaft 24, the lubricant can be automatically output and injected when the air pressure changes due to the change in the internal space of the injection tube 22, so that the lubricant forms a dynamic circulation inside the injection tube 22, ensuring that the outer wall of the driven pressure roller 14 always maintains a layer of appropriate lubricating film, and this dynamic lubrication method is more effective than static coating and can continuously provide lubrication effect;

[0047] Please refer to Fig. 9 - Fig.12As shown, the traction balancing mechanism 3 includes a buckle ring 31 symmetrically fixedly connected to the outer wall of the driven pressure roller 14, and an elastic curved rod 32 is installed inside the buckle ring 31.

The sliding shaft 34 and the limiting cylinder 36 are slidably connected through the cylindrical protrusion and the bending groove.

[0048] Specifically, the device can actively counteract the tendency of the driven pressure roller 14 to be slightly unbalanced due to wear and fatigue. Even if the cylinder body of the driven pressure roller 14 is partially worn and deformed, the support and traction of the hinge group 33 can maintain its stability to a certain extent to prevent its position from being excessively offset, thereby reducing the risk of failure caused by component imbalance.

[0049] The following are the complete usage steps and working principles of the above embodiment:

[0050] The use process of the device: before using the device, the staff first ensures that the outer surfaces of the active pressure roller 13 and the driven pressure roller 14 are clean and in good working condition, and that there are no impurities and residues. Then, according to the production requirements and the properties of the film, the parameters of the roller pressing device, including roller pressure, roller speed, temperature, etc., are adjusted to ensure that the parameters of the roller pressing device match the requirements of film preparation. Then, the roller pressing device is started. At this time, the driving motor 12 will drive the active pressure roller 13 and the driven pressure roller 14 to keep them rotating. Figure 1 As shown, at this time, the film forming body 15 passes through the rolling area between the active pressing roller 13 and the driven pressing roller 14, so that the film is pressed and stretched to obtain the desired thickness and flatness of the film;

[0051] The roller pressure anti-adhesion mechanism 2 is used to spray the solution when the driven pressure roller 14 rotates a certain number of times to prevent the plastic raw material from adhering to its surface.

[0052] like Figure 3As shown, since the transmission assembly 25 is composed of a linkage wheel, a driven wheel and a transmission belt, and the linkage wheels in the transmission assembly 25 are symmetrically fixedly connected to the two sides of the driven pressure roller 14, and the driven wheel is symmetrically fixedly connected to the ends of the through-shaft 24 that are far away from each other, when the above-mentioned staff starts the device and the driven pressure roller 14 keeps rotating, the linkage wheels located on both sides of the driven pressure roller 14 will drive the driven wheels to rotate synchronously through the transmission belt;

[0053] like Figures 3 to 5 As shown, since the driven wheel in the transmission assembly 25 keeps rotating, it will drive the through shaft 24 that is fixedly connected thereto to rotate synchronously. Since the through shaft 24 and the extrusion plate 26 form a ball screw structure, and the extrusion plate 26 is initially located at one end close to the transmission assembly 25, when the through shaft 24 keeps rotating, it will drive the extrusion plate 26 to move linearly along the upper surface of the partition plate 23 toward the direction of the stirring wheel 27.

[0054] like Figure 5 and Figure 6 As shown, since the liquid storage cylinder 21 and the injection tube 22 are initially filled with water-based lubricants, and the partition plate 23 as a whole divides the interior of the injection tube 22 into two equidistant upper and lower parts, specifically: the through-axis 24 is located in the upper half of the interior of the injection tube 22, and the delivery hose 28 is located in the lower half of the injection tube 22. Therefore, when the above-mentioned extrusion plate 26 keeps moving in a straight line, the space in the upper half of the interior of the injection tube 22 gradually becomes smaller, and at this time, the air pressure inside the injection tube 22 will continue to increase and be greater than the air pressure outside the injection tube 22. Therefore, with the continuous movement of the extrusion plate 26, the water-based lubricant inside the injection tube 22 will gradually be discharged from the delivery hose 28 in the lower half of the injection tube 22, and the discharged water-based lubricant will gradually flow to the interior of the patch shell 29 and make it in a wet state. At this time, when the driven pressure roller 14 that keeps rotating passes the position of the patch shell 29, its outer wall will continue to absorb the water-based lubricant on the surface of the patch shell 29 to form a lubricating film;

[0055] like Figure 6As shown in the figure, when the extrusion plate 26 is reversely reset as the through-shaft 24 is continuously rotated, the air pressure inside the injection tube 22 will continue to decrease and become less than the air pressure outside the injection tube 22. Therefore, as the extrusion plate 26 is reversely reset, the water-based lubricant inside the injection tube 22 will stop being discharged from the delivery hose 28 at the lower half of the injection tube 22. Since the liquid storage cylinder 21 and the injection tube 22 are connected, and the liquid storage cylinder 21 and the delivery hose 28 are both installed with a one-way valve, when the water-based lubricant inside the injection tube 22 is discharged, the liquid storage cylinder 21 and the delivery hose 28 are connected. When the output stops, the liquid storage cylinder 21 will automatically add enough water-based lubricant to its interior until the water-based lubricant capacity inside the injection tube 22 is equal to the initial capacity, and as the through-shaft 24 continues to rotate, the extrusion plate 26 will repeat the above movement inside it, thereby wetting the outer wall of the driven pressure roller 14 to prevent it from sticking during the rolling process. In addition, since the liquid storage cylinder 21 is made of transparent material as a whole and the interior of the liquid storage cylinder 21 is connected to a liquid refilling tube, the staff can directly observe the remaining amount of water-based lubricant inside the liquid storage cylinder 21 and replenish it in time;

[0056] like Figure 6 and Figure 7 As shown, the position of the stirring wheel 27 is specifically at the boundary between the upper and lower layers inside the injection tube 22, and at the output port of the liquid storage cylinder 21 for inputting the water-based lubricant. Therefore, no matter the above-mentioned output of the lubricant inside the injection tube 22, or the lubricant transported from the liquid storage cylinder 21 to the inside of the injection tube 22, the flowing lubricant will pass through the position of the stirring wheel 27. Since the stirring wheel 27 is fixedly connected to the through shaft 24, the through shaft 24 will rotate synchronously with the stirring wheel 27, and the stirring wheel 27 that keeps rotating will continuously stir the flowing lubricant, thereby preventing the lubricant from self-precipitation when it is in the liquid storage cylinder 21 or the injection tube 22 for a long time.

[0057] rely on Figure 7 and Figure 8 Combination Figure 4 It can be seen that the end of the scraper plate 210 away from the patch shell 29 tends to fit the uppermost end of the outer wall of the driven pressure roller 14, and the end of the scraper plate 210 away from the patch shell 29 is curved, while the end of the scraper plate 210 close to the patch shell 29 is inclined straight. Therefore, when the driven pressure roller 14 is rolling, if there are impurities on the plastic raw material on its outer wall, or dust particles in the working environment air remain on the outer wall of the driven pressure roller 14, the curved part of the scraper plate 210 will scrape off the impurities on the surface of the driven pressure roller 14 as the driven pressure roller 14 rotates, and the scraped impurities will continue to slide down along the inclined part of the scraper plate 210, thereby avoiding the problem of clogging of the curved part of the scraper plate 210 due to long-term treatment of impurities;

[0058] The traction balancing mechanism 3 for maintaining the parallelism between the active pressure roller 13 and the driven pressure roller 14 is specifically used as follows:

[0059] When the driven roller 14 is in use for a long time or subjected to heavy pressure, fatigue, thermal expansion or uneven load distribution of its own material will cause its own shape to change, such as wear and deformation of the cylinder body, thereby affecting the parallelism between the active roller 13 and the driven roller 14;

[0060] like Fig. 9 and Fig.10 As shown, in the initial state, the active pressure roller 13 and the driven pressure roller 14 are in the same vertical plane and are kept parallel to each other. At this time, the left and right sides of the driven pressure roller 14 are kept in a supported suspension state through the buckle 31 and the elastic curved rod 32. Since the active pressure roller 13 and the driven pressure roller 14 are kept parallel to each other at this time, the elastic curved rod 32 is in an inverted isosceles triangle state as a whole, and under the suspension traction of the elastic curved rod 32, the hinge group 33 is in a regular triangle contracted state at this time;

[0061] However, when the driven pressure roller 14 is used for a long time, its outer part is worn and fatigued due to heavy pressure, and the mass of the driven pressure roller 14 itself will be uneven due to wear. At this time, the geometric shape of the driven pressure roller 14 changes, which leads to a decrease in its concentricity and causes offset imbalance. At this time, no matter whether the driven pressure roller 14 is offset to the left or right as a whole, both ends of the driven pressure roller 14 will pull the elastic curved rod 32 downward through the buckle ring 31 on one side and squeeze the elastic curved rod 32 upward through the buckle ring 31 on the other side due to the offset force. At this time, the elastic curved rods 32 on both sides of the driven pressure roller 14 will synchronously pull downward and squeeze upward the hinge group 33, such as Fig. 9 As shown, since the hinge group 33 is installed as a whole inside the equipment support 11, and the top intersection position of the hinge group 33 is kept in contact with the sliding shaft 34, when the elastic curved rod 32 is pulled downward by the traction force to pull the hinge group 33, the hinge group 33 will gradually rotate along the inner wall of the equipment support 11 to make its own contraction angle smaller, and when the elastic curved rod 32 on the other side is pressed upward to lift the hinge group 33, the hinge group 33 will gradually rotate along the inner wall of the equipment support 11 to make its own contraction angle larger, thereby offsetting the unbalanced bias trend of the driven pressure roller 14 through the change of traction of the elastic curved rod 32;

[0062] like Fig.11 and Fig.12As shown, as the above-mentioned hinge group 33 moves downward or upward as a whole, the gear at the intersection of the hinge group 33 will drive the sliding shaft 34 to move when it rotates, thereby causing the sliding shaft 34 to move upward or downward synchronously. Since the sliding shaft 34 and the limiting cylinder 36 are slidingly connected through the cylindrical protrusion and the curved groove, and the sliding shaft 34 and the limiting cylinder 36 are symmetrically installed above the equipment bracket 11, when the above-mentioned sliding shaft 34 moves along the inner wall of the limiting cylinder 36, the cylindrical protrusion on its outer wall will continue to rotate along the inner wall of the curved groove and gradually rotate. Therefore, with the action of the rotating friction force at the intersection of the above-mentioned hinge group 33, the specific movement form of the sliding shaft 34 is rotational up and down movement, and as the sliding shaft 34 rotates in the opposite direction at the same time, it will drive the pointer 35 to rotate in the opposite direction, thereby making the tip positions of the pointer 35 on both sides of the driven pressure roller 14 correspond to each other, thereby reminding the staff that the driven pressure roller 14 is in a state of position imbalance.
