Description

Technical Field

[0001] The invention relates to the technical field of calenders, and in particular to a calender for preparing cloth from thermoplastic materials. Background Art

[0002] Thermoplastic materials refer to plastics that soften when heated and harden when cooled. They are commonly used in parts of the automotive industry, consumer goods, and other parts in our lives. The function of the calender is to press and stretch rubber or plastic into a film of a certain thickness and surface shape, and it can also scrape glue on fiber cords or steel cords. For example, prepregs and the inner cord fabric of automobile tires. In the field of thermoplastic material preparation, the calender is a branch. However, in the production field involving prepregs, the calender is a crucial step. Its process level, processing technology, and production speed are directly related to the development of the industry involving the production and use of prepregs.

[0003] In the continuous production process of the existing calender, the surface temperature of the roller is difficult to accurately control, or the viscosity of the thermoplastic raw material is relatively high. This may cause the waste glue on the roller to stick to the thermoplastic raw material on the cloth during use of the calender roller, thereby affecting the production quality of the product. In the prior art, to solve this problem, the detection equipment generally detects that there is waste material attached to the roller surface, and then uses a scraper plate or the like to perform subsequent cleaning operations on the roller surface. However, the use of a hard scraper plate may cause scratches or wear on the surface of the rolling roller, affecting its flatness and finish, which will not only reduce the service life of the rolling roller, but also may affect the quality and performance of the final product, and seriously affect the production efficiency of the product.

DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

[0035] Embodiment 1, refer to Figure 1-Figure 11 A calender for preparing cloth from thermoplastic material, comprising a base 1, side plates 2 are provided at both ends of the base 1, the side plates 2 are connected with a lifting plate 10 and a hydraulic cylinder 11, an electric telescopic rod 6, a rolling roller 7 and a rotating shaft 9 are provided above the base 1, a motor 3 is provided at one end of the rotating shaft 9, and further comprising:

[0036] An adjustment component 4, the adjustment component 4 is located on one side of the side plate 2, and the adjustment component 4 is used to adjust the applicable height of the electric telescopic rod 6;

[0037] A cleaning component 5, which is located on one side of the rolling roller 7, and uses pressure to clean the attachments on the surface of the rolling roller 7;

[0038] The limiting component 8 is located at one side of the cleaning component 5 , and the limiting component 8 uses its own spatial range to ensure the stable movement of the cleaning component 5 .

[0039] Furthermore, the side panel 2 is fixedly connected to the base 1, the inner wall of the side panel 2 slides with the two ends of the lifting plate 10, the upper end of the side panel 2 is fixedly connected to the hydraulic cylinder 11, and one end of the hydraulic cylinder 11 vertically penetrates the inner wall of the side panel 2 and is fixedly connected to the lifting plate 10.

[0040] Adjustment of fabric thickness: a roller (not marked in the figure) is provided at a fixed position below the side plate 2, and the roller is rotated by a driving device, so that the fabric can be rolled in cooperation with the rolling roller 7, and the lifting plate 10 can be controlled by the hydraulic cylinder 11 to slide on the inner wall of the side plate 2 to adjust the rolled thickness of the fabric, so that fabrics of different thicknesses can be processed to improve the use range of the equipment, and a spring is provided between the lifting plate 10 and the inner wall of the side plate 2. In the process of the hydraulic cylinder 11 driving the lifting plate 10 to move, the stability of the up and down movement of the rolling roller 7 can be increased by compressing and stretching the spring, thereby ensuring the uniformity of the fabric thickness during processing and the accuracy of the adjustment.

[0041] Reference Figure 1-Figure 3, further; the rolling roller 7 is fixedly sleeved on the outer wall of the rotating shaft 9, both ends of the rotating shaft 9 are rotatably connected with the corresponding lifting plates 10, the side walls of the lifting plates 10 are fixedly connected with the motor 3, one end of the rotating shaft 9 passes through the side wall of the lifting plate 10 and is fixedly connected with the motor 3, and a plurality of limit blocks 71 are distributed in a circumferential array at both ends of the rolling roller 7, the limit blocks 71 are arranged in an "L" shape, one end of the limit block 71 is fixedly connected to the side wall of the rolling roller 7, and the side wall of the limit block 71 is fixedly connected with a magnetic iron 72.

[0042] Rolling of the rolling roller 7: When the cloth is rolled, after adjusting the height of the rolling roller 7, the motor 3 is started to work, thereby driving the rotating shaft 9 to rotate, thereby driving the rolling roller 7 to start working. During the processing, in order to avoid the increase in cost caused by the deviation or falling of the cloth, "L"-shaped limit blocks 71 are set on both sides of the rolling roller 7. This can limit the left and right movement range of the cloth during the processing, thereby preventing the cloth from deviating significantly or falling off the surface of the rolling roller 7. The setting of the magnetic iron 72 is limited to the limit block 71 at one end of the rolling roller 7, which can reduce unnecessary use and thus reduce production costs.

[0043] Furthermore; the adjustment component 4 includes a second motor 41, a threaded rod 42 and a bearing seat 43, the bearing seat 43 is fixedly connected to the side wall of the side plate 2, the bearing seat 43 is rotatably connected to the threaded rod 42, the second motor 41 is fixedly connected to the bearing seat 43, and the second motor 41 is fixedly connected to one end of the threaded rod 42.

[0044] Height adjustment of the cleaning component 5 and the limiting component 8: When the rolling roller 7 stops, the motor 2 41 can be started to drive the threaded rod 42 to rotate on the bearing seat 43, and then the height between the cleaning component 5 and the limiting component 8 and the base 1 is adjusted by adjusting the threaded connection between the seat 44 and the threaded rod 42, and the cleaning component 5 and the limiting component 8 are adjusted to one side of the central axis of the rolling roller 7, so that the two fixed plates 51 are symmetrically distributed about the central axis of the rolling roller 7. The advantage of doing this is to ensure that the maximum effective cleaning area is maintained during subsequent cleaning, and after cleaning the rolling roller 7, the roller in the fixed position below can continue to be moved and adjusted in the same way, thereby reducing the use of multiple cleaning equipment and saving costs.

[0045] Furthermore, the adjustment assembly 4 also includes an adjustment seat 44, both ends of the adjustment seat 44 are respectively threadedly connected to the corresponding threaded rod 42, the side wall of the adjustment seat 44 is fixedly connected to the electric telescopic rod 6, and one end of the electric telescopic rod 6 is fixedly connected to a rotating plate 61.

[0046] It should be noted that the height of the electric telescopic rod 6 is adjusted as the adjustment seat 44 moves up and down, and when cleaning is not needed, the moving end of the electric telescopic rod 6 is in a retracted state, and the cleaning head 53 is located at one side of the rolling roller 7 at this time. Therefore, during the process of the cleaning component 5 moving up and down, it will not contact the side wall of the rolling roller 7, which can prevent the impurities on the surface of the cleaning head 53 from falling off to the surface of the rolling roller 7 due to friction, thereby affecting the surface flatness of the rolling roller 7. These impurities are accumulated by the attachments on the surface of the rolling roller 7 before cleaning. At this time, the impurities attached to the surface of the cleaning head 53 are less, so it is not necessary to clean it, and it will not affect the subsequent cleaning of the attachments on the surface of the rolling roller 7.

[0047] Therefore, when cleaning the surface of the rolling roller 7, the electric telescopic rod 6 can be started, so that the moving end of the electric telescopic rod 6 drives the rotating plate 61 to approach one side of the rolling roller 7, and through the rotation connection between the connecting plate 85 and the rotating plate 61, the fixed plate 51 and the support plate 81 form an angle of 30 degrees with the base 1. The advantage of this is that the cleaning head 53 can contact the outer wall of the rolling roller 7 with the maximum area, thereby increasing the cleaning area of ​​the surface of the rolling roller 7 to ensure the cleaning effect.

[0048] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 , further; the limit assembly 8 includes a support plate 81, one side of the support plate 81 is fixedly connected to a connecting plate 85, the connecting plate 85 is rotatably connected to the rotating plate 61, and the other side of the limit assembly 8 is provided with a limit slide groove 84, the inner wall of the limit slide groove 84 is fixedly connected to a limit slide rod 83, and the outer walls of both ends of the limit slide rod 83 are sleeved with buffer springs 82.

[0049] Function of the limit assembly 8: The rotational connection between the connecting plate 85 and the rotating plate 61 can ensure a better tilt angle of the support plate 81, thereby more effectively assisting the work of the cleaning assembly 5, and the mutual cooperation between the limit slide groove 84 and the limit slide rod 83, on the one hand, ensures the smoothness of the limit slider 57 during the movement, and on the other hand, limits the moving range of the limit slider 57 to prevent the limit slider 57 from detaching. In addition, the buffer spring 82 will be compressed and stretched during the movement of the limit slider 57, which can effectively provide stability for the movement of the limit slider 57, so as to reduce the damage to the cleaning assembly 5 caused by direct collision between the gaps, thereby improving the service life of the equipment.

[0050] Example 2, refer to Figure 4-Figure 11, further; the cleaning assembly 5 includes a fixed plate 51, one side of the fixed plate 51 is fixedly connected to a limiting slider 57, the limiting slider 57 is slidably sleeved on the outer wall of the limiting slide rod 83, the limiting slider 57 is slidably connected to the limiting slide groove 84, the side wall of the limiting slider 57 is fixedly connected to one end of the buffer spring 82, the other end of the buffer spring 82 is fixedly connected to the inner wall of the limiting slide groove 84, and the side wall of the fixed plate 51 is fixedly connected with a magnetic attraction strip 55.

[0051] The magnetic strip 55 cooperates with the magnetic iron 72: during the rotation of the rolling roller 7, the magnetic iron 72 is driven to rotate synchronously through the connection of the limit block 71. In addition, the end of the magnetic iron 72 close to the rolling roller 7 has the same magnetic property as the end of the magnetic strip 55 away from the fixed plate 51. Therefore, when the magnetic iron 72 approaches the magnetic strip 55, due to the mutual repulsion between the same magnetic properties, the magnetic iron 72 exerts a force on the magnetic strip 55, and cooperates with the action of the limit slide bar 83 and the limit slide groove 84, so that the limit slide block 57 drives the fixed plate 51 to move toward the side of the motor 3, thereby driving the multiple cleaning heads 53 to move horizontally on the surface of the rolling roller 7. After the magnetic attractor 72 moves away from the magnetic attraction bar 55, the buffer spring 82 is elastically restored, so that the fixed plate 51 is reset while squeezing the buffer spring 82 on the other side and waiting for the action of the next magnetic attractor 72, thereby forming a periodic movement, thereby expanding the cleaning area of ​​the cleaning head 53 and eliminating the cleaning blind spots between each cleaning head 53, making the cleaning effect more uniform and improving the cleaning effect. In addition, after the cleaning is completed, the resistance during the movement of the limit slider 57 and the fixed plate 51 can prevent the buffer spring 82 from constantly rebounding, and finally the limit slider 57 and the fixed plate 51 can return to their initial positions.

[0052] Furthermore, the cleaning assembly 5 also includes a positioning plate 52, which is fixedly connected to the side of the fixed plate 51 away from the limiting slider 57, and the side wall of the positioning plate 52 is provided with a mounting groove 521, and the inner wall of the mounting groove 521 is fixedly connected with an extrusion strip 522, and telescopic springs 56 are provided on both sides of the positioning plate 52.

[0053] Restriction of the positioning plate 52: By opening a mounting groove 521 inside the positioning plate 52, the moving space of the mounting plate 54 can be restricted to prevent the mounting plate 54 from falling off, and the stable movement of the mounting plate 54 can be ensured to reduce shaking, so that the cleaning head 53 is more powerful when cleaning the attachments on the outer wall of the rolling roller 7. In addition, the positioning plate 52 and the fixing plate 51 can be detachably installed, which makes it easy to replace and repair the mounting plate 54, improves the maintenance efficiency, and also facilitates the cleaning of the cleaning head 53, thereby ensuring the cleaning effect.

[0054] Furthermore; a plurality of evenly distributed cleaning heads 53 are fixedly connected to one side of the mounting plate 54 away from the fixing plate 51, a cross groove 531 is provided at one end of the cleaning head 53 away from the mounting plate 54, and a ball head groove 532 is provided on the side wall of the cleaning head 53, the depth of the ball head groove 532 is greater than the depth of the cross groove 531.

[0055] Specific application of the cleaning head 53: The cleaning head 53 is made of high-temperature resistant rubber material and has excellent wear resistance and friction performance. This not only ensures the service life of the cleaning head 53, but also increases the friction force between the cleaning head 53 and the rolling roller 7, which can improve the cleaning degree. During the rotation of the rolling roller 7, the surface of the rolling roller 7 is longitudinally cleaned by the cleaning head 53, and the left and right movement of the cleaning head 53 can increase the cleaning degree, so that the attachments on the surface of the rolling roller 7 can be cleaned more cleanly and thoroughly. The mutual cooperation of horizontal cleaning and vertical cleaning can effectively improve the cleaning efficiency, and during the cleaning process, the cross groove 531 can cooperate to better scrape the attachments on the surface of the rolling roller 7, and the attachments can be temporarily stored in the ball head groove 532, or the attachments can be directly scraped off, so as to avoid impurities adhering to the surface of the cleaning head 53 and affecting the subsequent cleaning effect.

[0056] Furthermore, the cleaning assembly 5 also includes a mounting plate 54, which is slidably connected to the inner wall of the mounting groove 521, and the lower side wall of the mounting plate 54 is fixedly connected to one end of the telescopic spring 56, and the other end of the telescopic spring 56 is fixedly connected to the inner wall of the mounting groove 521. An electric heating rod 541 is provided inside the mounting plate 54, and a touch pressure plate 542 is fixedly connected to the lower side wall of the mounting plate 54, and the touch pressure plate 542 is electrically connected to the electric heating rod 541.

[0057] Automatic cleaning of accumulated impurities in the cleaning head 53: When there are more impurities stored at the end of the cleaning head 53, the weight of the entire cleaning head 53 will increase accordingly. In the process of impurity accumulation, the increase in weight will drive the mounting plate 54 to gradually move downward, thereby compressing the telescopic spring 56. When the impurities accumulate to a certain weight, the mounting plate 54 will drive the contact plate 542 to contact the extrusion strip 522. At this time, the electric heating rod 541 is powered on and starts to work. As the temperature rises, the impurities accumulated inside the cross groove 531 and the ball head groove 532 will gradually melt, thereby causing the impurities to separate from the cleaning head 53 and automatically fall off. Some impurities fall onto the surface of the rolling roller 7, but they will also be cleaned up later. Therefore, during the process of impurity separation, the overall weight of the cleaning head 53 is reduced, which causes the telescopic spring 56 to gradually begin to recover elastically and drive the mounting plate 54 to move up and reset. At the same time, the contact plate 542 and the extrusion strip 522 are separated. At this time, the electric heating rod 541 is no longer powered on for heating, but the electric heating rod 541 can continue to melt the impurities through the residual heat until it cools down and waits for the next heating, so as to ensure the cleanliness of the end of the cleaning head 53, thereby ensuring the effect of cleaning the attachments on the surface of the rolling roller 7 and reducing the number of manual cleaning of the cleaning head 53.

[0058] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
