Description

Technical Field

[0001] The present application belongs to the technical field of calenders, and in particular to a calender. Background Art

[0002] Plastic calender is mainly used in the production of various types of plastic films and PVC calendering artificial leather products. It usually has four main rollers or five main rollers to press the plastic evenly.

[0003] Publication number CN219650411 U A plastic calender, belonging to the field of intelligent equipment technology. Support base plate, the upper surface of the support base plate is fixedly connected with support vertical block 1 and support vertical block 2, between the support vertical block 1 and support vertical block 2 are provided with calendering rolling shaft 1 and calendering rolling shaft 2, the outer surface of the calendering rolling shaft 1 is sleeved with two adjustment plates 1, and the outer surface of the calendering rolling shaft 2 is sleeved with two adjustment plates 2.

[0004] The above patent limits the width of the pressed product by adjusting the distance between two adjustment plates one and two adjustment plates two. However, in actual use, due to the setting and coordination of driving structures such as hydraulic telescopic rods, the linkage between the structures is relatively complicated, making it difficult to clean the plastic raw materials and ink marks contaminated on the calendering rolling shaft after calendering. If things go on like this for a long time, the flatness of the outer wall of the calendering roller will be reduced, which will eventually affect the overall processing and needs to be improved. Utility Model Content

[0005] The purpose of this application is to provide a calender that can solve the above problems.

[0006] The purpose of this application is to provide a calender, comprising:

[0007] A base, wherein a first vertical plate and a second vertical plate are arranged on the base, and a top plate is arranged on the first vertical plate and the second vertical plate;

[0008] A calendering mechanism, comprising a first calendering roller and a second calendering roller arranged at intervals, and a driving structure for driving the first calendering roller and the second calendering roller;

[0009] A cleaning mechanism is disposed between the first vertical plate and the second vertical plate and is used to clean the first calendering roller and the second calendering roller;

[0010] There are two cleaning mechanisms, which clean the first calendering roller and the second calendering roller respectively.

[0011] The base, the first vertical plate, the second vertical plate and the top plate together constitute the main frame of the calender, providing stable support for the calendering mechanism and the cleaning mechanism, ensuring the stability and reliability of the calender during operation. By setting up two cleaning mechanisms, the first calendering roller and the second calendering roller are cleaned respectively, which effectively ensures the cleanliness of the calendering roller. During the calendering process, materials may remain on the calendering roller, affecting the calendering quality and roller surface wear. Through regular cleaning, the residues can be removed to maintain the finish and service life of the calendering roller. In addition, through the precise driving structure and the calendering rollers set at intervals, precise calendering processing of the material can be achieved. During the calendering process, the material undergoes plastic deformation under the action of the calendering roller to form the required shape and size. Due to the high cleanliness of the calendering roller, the calendering quality problems and roller surface wear problems caused by residues can be reduced, thereby improving the service life and economic benefits of the calender.

[0012] Furthermore, the cleaning mechanism comprises:

[0013] A mounting frame, one side of which is provided with a driving motor, an output shaft of the driving motor is provided with a screw rod, a mounting seat is provided on the screw rod, and a scraper is provided on the mounting seat;

[0014] A support plate is arranged on a side of the installation frame away from the screw rod, and an electric lifting rod is arranged between the support plates;

[0015] The scraper and the mounting seat are detachably connected.

[0016] The drive motor drives the screw to rotate, and the mounting seat and scraper move back and forth along the screw to clean the calender roller. This cleaning method is more efficient than manual cleaning and can quickly remove residues on the calender roller in a short time. The setting of the electric lifting rod allows the height of the scraper to be accurately adjusted to adapt to calender rollers of different sizes and shapes, ensuring the appropriate spacing between the scraper and the calender roller, avoiding the cleaning effect or scratching the calender roller due to excessive or too small spacing. The detachable connection design between the scraper and the mounting seat allows the scraper to be easily replaced after wear or damage, reducing maintenance costs and downtime. At the same time, the cleaning mechanism is located in the safe area of ​​the calender, away from the high temperature and high-speed rotating calender roller, reducing the risk of operator injury.

[0017] Further: the driving structure includes:

[0018] A first end face gear is arranged on one side of the first calendering roller;

[0019] A second end face gear is arranged on one side of the second calendering roller;

[0020] A servo motor is arranged on one side of the first vertical plate, and a power gear is arranged on the output shaft of the servo motor, and the power gear is meshed with the first end face gear and the second end face gear;

[0021] The servo motor, the first calendering roller and the second calendering roller are perpendicular to each other, and the power gear is in the shape of a long strip.

[0022] The servo motor is used as a driving source. The power gear on the output shaft meshes with the first end face gear and the second end face gear to achieve synchronous rotation of the first calendering roller and the second calendering roller. This transmission method is highly efficient and can ensure the stability and accuracy of the calendering roller during operation. The servo motor has the characteristics of high-precision control. By adjusting the control parameters of the servo motor, the speed and direction of the calendering roller can be accurately controlled to meet the calendering requirements of different materials. The servo motor is perpendicular to the first calendering roller and the second calendering roller, and the power gear is in a long strip shape. This design makes the entire drive structure more compact, reduces the floor space, and is convenient for installation and layout in a limited space. At the same time, the end face gear has the advantages of smooth transmission, low noise, and long life. The end face gear is used for transmission in the calender, which can ensure the stability and reliability of the calendering roller during long-term continuous operation. And because the structure of the servo motor and the end face gear is relatively simple and easy to disassemble and install, the maintenance cost of the entire drive structure is low. In the event of a failure, it can be quickly repaired and replaced, reducing downtime and improving production efficiency.

[0023] Furthermore, a mounting cover is provided on one side of the first vertical plate, the servo motor, the power gear, the first end face gear and the second end face gear are all arranged in the mounting cover, and a heat dissipation port is provided on one side of the mounting cover.

[0024] The installation cover can provide protection for the internal drive components, preventing interference and damage to the drive components by external factors such as dust and debris, thereby extending the service life of the equipment. The installation cover isolates the drive components from the external environment, reduces the dangers that operators may be exposed to during maintenance or adjustment, and improves work safety. The heat generated inside can be effectively discharged through the heat dissipation port set on one side of the installation cover, preventing the drive components from being damaged or performance degradation due to overheating. The installation cover is detachable or openable, which can easily inspect, maintain or replace the internal drive components when necessary.

[0025] Furthermore, the second vertical plate is provided with:

[0026] a first mounting groove, wherein a first bearing adapted to the first calendering roller is disposed in the first mounting groove;

[0027] a second mounting groove, wherein a second bearing adapted to the second calendering roller is disposed in the second mounting groove;

[0028] Wherein, the first installation slot and the second installation slot are respectively provided with a first maintenance door and a second maintenance door.

[0029] The first and second calendering rollers are supported by the first and second bearings, which ensures the stability and reliability of the calendering rollers during rotation, reduces the vibration and deviation of the calendering rollers, and improves the accuracy and efficiency of the calendering operation. The first and second mounting grooves provide convenience for the installation and removal of the calendering rollers. The operator can easily put the calendering rollers into or take them out of the mounting grooves by opening the corresponding maintenance doors, which greatly simplifies the installation and removal process. The maintenance of the calendering rollers and bearings becomes more convenient. When the calendering rollers or bearings need to be inspected, replaced or lubricated, the operator only needs to open the corresponding maintenance door to perform maintenance work without disassembling the entire calender.

[0030] Furthermore, a plurality of supporting feet are arranged at the bottom of the base, and a shock-absorbing pad is arranged at the bottom of each supporting foot.

[0031] The design of multiple support feet can evenly distribute the weight of the calender, increase its overall stability, help reduce the vibration and shaking of the calender during operation, and ensure the accuracy and efficiency of the calendering operation. By setting a shock-absorbing gasket at the bottom of each support foot, the vibration and noise generated by the calender can be effectively absorbed and reduced, which not only improves the working environment quality of the calender and reduces noise pollution, but also reduces the damage of vibration to the equipment itself and the surrounding environment. It also plays a role in protecting the ground. Through the buffering effect of the shock-absorbing gasket, the pressure and wear on the ground can be reduced, and the service life of the ground can be extended.

[0032] The beneficial effects of this application are:

[0033] 1. By setting up two cleaning mechanisms and cleaning regularly, the residues can be removed to maintain the smoothness and service life of the calendering roller. During the calendering process, the material undergoes plastic deformation under the action of the calendering roller to form the required shape and size. Due to the high cleanliness of the calendering roller, the calendering quality problems and roller surface wear problems caused by the residues can be reduced, thereby improving the service life and economic benefits of the calendering machine.

[0034] 2. The servo motor is used as the driving source. The power gear on the output shaft meshes with the first end gear and the second end gear to achieve synchronous rotation of the first calendering roller and the second calendering roller. The servo motor is perpendicular to the first calendering roller and the second calendering roller, and the power gear is in the shape of a long strip. This design makes the entire drive structure more compact, reduces the floor space, and is convenient for installation and layout in a limited space.

[0035] 3. The first installation groove and the second installation groove provide convenience for the installation and removal of the calendering roller. The operator can easily put the calendering roller into or take it out of the installation groove by opening the corresponding maintenance door, which greatly simplifies the installation and removal process.

DETAILED DESCRIPTION

[0040] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0041] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0042] The calender provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0043] Embodiment 1:

[0044] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides a calender, comprising:

[0045] A base 100, a first vertical plate 110 and a second vertical plate 120 are disposed on the base 100, and a top plate 130 is disposed on the first vertical plate 110 and the second vertical plate 120;

[0046] The calendering mechanism 200 includes a first calendering roller 210 and a second calendering roller 220 which are arranged at intervals, and a driving structure 230 for driving the first calendering roller 210 and the second calendering roller 220;

[0047] The cleaning mechanism 300 is disposed between the first vertical plate 110 and the second vertical plate 120 and is used to clean the first calendering roller 210 and the second calendering roller 220;

[0048] There are two cleaning mechanisms 300 , and the two cleaning mechanisms 300 clean the first calendering roller 210 and the second calendering roller 220 respectively.

[0049] In some implementations of the embodiments of the present application, Figure 1 As shown, the base 100, the first vertical plate 110, the second vertical plate 120 and the top plate 130 together constitute the main frame of the calender, providing stable support for the calender mechanism 200 and the cleaning mechanism 300, ensuring the stability and reliability of the calender during operation. By setting two cleaning mechanisms 300, the first calender roller 210 and the second calender roller 220 are cleaned respectively, which effectively ensures the cleanliness of the calender roller. During the calendering process, the material may remain on the calender roller, affecting the calendering quality and roller surface wear. Through regular cleaning, the residue can be removed to maintain the finish and service life of the calender roller. In addition, through the precise driving structure 230 and the calender rollers arranged at intervals, the precise calendering treatment of the material can be achieved. During the calendering process, the material undergoes plastic deformation under the action of the calender roller to form the desired shape and size. Due to the high cleanliness of the calender roller, the calendering quality problem and roller surface wear problem caused by the residue can be reduced, and the service life and economic benefits of the calender can be improved.

[0050] Furthermore, a plurality of supporting legs 600 are disposed at the bottom of the base 100 , and a shock-absorbing pad 610 is disposed at the bottom of each supporting leg 600 .

[0051] The design of multiple support legs 600 can evenly distribute the weight of the calender, increase its overall stability, help reduce the vibration and shaking generated by the calender during operation, and ensure the accuracy and efficiency of the calendering operation. By arranging a shock-absorbing gasket 610 at the bottom of each support leg 600, the vibration and noise generated by the calender can be effectively absorbed and reduced, which not only improves the working environment quality of the calender and reduces noise pollution, but also reduces the damage caused by vibration to the equipment itself and the surrounding environment. It also plays a role in protecting the ground. Through the buffering effect of the shock-absorbing gasket 610, the pressure and wear on the ground can be reduced, and the service life of the ground can be extended.

[0056] The support plate 360 ​​is arranged on a side of the installation frame 310 away from the screw rod 330, and an electric lifting rod 370 is arranged between the support plates 360;

[0057] The scraper 350 and the mounting seat 340 are detachably connected.

[0058] In the embodiment of the present application, the screw rod 330 is driven to rotate by the driving motor 320, and the mounting seat 340 and the scraper 350 reciprocate along the screw rod 330, so as to clean the calendering roller. This cleaning method is more efficient than manual cleaning and can quickly remove the residue on the calendering roller in a short time. The setting of the electric lifting rod 370 allows the height of the scraper 350 to be accurately adjusted to adapt to calendering rollers of different sizes and shapes, ensuring the appropriate spacing between the scraper 350 and the calendering roller, avoiding the cleaning effect or scratching the calendering roller due to excessive or too small spacing. The detachable connection design between the scraper 350 and the mounting seat 340 allows the scraper 350 to be easily replaced after wear or damage, reducing maintenance costs and downtime. At the same time, the cleaning mechanism 300 is located in a safe area of ​​the calender, away from the high temperature and high-speed rotating calendering roller, reducing the risk of injury to the operator.

[0059] Embodiment 3:

[0060] An embodiment of the present application provides a calender. In addition to the above-mentioned technical features, the calender in the embodiment of the present application also includes the following technical features.
