Description

Technical Field

[0001] The invention relates to the technical field of calenders, in particular to a calender with adjustable tension. Background Art

[0002] The calender is composed of two or more rollers, which are arranged according to the heating method. It can be divided into cold pressing and hot pressing. Cold pressing is suitable for materials that do not require heating, such as graphite film, graphite sheet, absorbing material, shielding material, magnetic material, non-ferrous metal material, etc. Hot pressing is divided into water heating, electric heating, oil heating and electromagnetic heating. They are all machines that press and extend rubber, silicone, silicone rubber, phase change material, PTFE or plastic into a film of a certain thickness and surface shape at a certain temperature, and can coat fiber curtain canvas or steel cord with glue. The calender can be divided into two-roller, three-roller, four-roller and five-roller calenders according to the number of rollers; according to the arrangement of the rollers, it can be divided into "L" type, "T" type, "F" type, "Z" type and "S" type.

[0003] The calender needs to repeatedly calender the material before discharging it for three reasons: first, to improve uniformity, make the ingredients evenly distributed, and eliminate internal defects; second, to adjust the performance, control the thickness and dimensional accuracy, and improve the physical properties; third, to improve production efficiency and product quality stability, optimize process parameters, and adapt to large-scale production. However, the existing calender cannot guide the calendered material when in use, and the staff needs to manually take over the falling material. The staff's hands directly reach under the roller structure, which is very dangerous and inconvenient for the staff to take the material to complete the repeated calendering operation. At the same time, the existing calender cannot tension the material during the discharging process. The sheeted material after calendering is prone to folding or wrinkling, which affects the discharging quality and is inconvenient to use. Summary of the invention

[0018] Compared with the prior art, the present invention provides a calender with adjustable tension, which has the following beneficial effects: 1. The calender with adjustable tension guides the material falling through the calendering equipment through the setting of the guide mechanism and the slide cylinder, so that the material will not fall on the right side of the blanking guide frame, ensuring that the blanking guide frame can limit the material when the material is transmitted to the right, thereby increasing the stability of material transportation. At the same time, the slidable return plate allows the staff to decide whether to discharge the material according to the specific state of the material, so that the staff does not need to put their hands under the calendering equipment, thereby increasing the safety of the staff, and the material that does not meet the standard can be discharged to the left and continue to be in the calendering equipment. The circulation increases the density of the material, increases the structural strength of the material after it is formed into sheets, and improves the material's bearing capacity during subsequent tensioning processing, making it easier for staff to tension the discharged material without breaking it, making it easier for staff to use. After the material has been repeatedly calendered, the staff only needs to adjust the return plate downward to make the material fall to the top of the conveyor belt, so that the material continues to move to the right at the top of the conveyor belt to pass over the top of the tensioning drum below, so that the subsequent tensioning drums on the upper and lower sides can cooperate to directly complete the tensioning processing of the material.

[0019] 2. The calender with adjustable tension, through the positioning mechanism, in the process of the return plate moving upward, drives the triangular slider to slide to the upper right through the limit slide bar, and squeezes the triangular block outward through the corresponding inclined surfaces of the triangular slider and the triangular block, and then completes the positioning of the triangular slider through the flat surface fitting of the triangular block and the triangular slider, so that the staff only needs to control the return plate to move directly upward to the top to complete the positioning of the return plate and the recovery of the fallen materials. At the same time, the staff only needs to pull the pull rod outward, and the return plate can slide downward under the action of gravity, so that the staff can quickly complete the change of the position status of the return plate. The operation is simple and convenient for the staff to use.

[0020] 3. The calender with adjustable tension has a tensioning mechanism. The staff only needs to start the servo motors on the front and rear sides to control the tensioning drums on the upper and lower sides to move inward synchronously, so that the tensioning drums on the upper and lower sides support the extruded materials to be transmitted to the right in a multi-stage Z-shaped state. The staff only needs to control the distance that the tensioning drums on the upper and lower sides move inward across the center line to control the degree of tensioning of the material when the device is in use, which is convenient for the staff to tension the synchronous material and adjust it. The operation is simple and convenient for the staff to use. At the same time, the tensioning drums on the upper and lower sides are in contact with the upper and lower sides of the material during the process of tensioning the material to smooth the material, so that the material is smoothed during the discharging process without wrinkles, and there is no need for the staff to manually smooth it later, which is convenient for the staff to use.

Then the staff can place the material on the calendering device 5, so that the calendering device 5 calenders the material. Then the material falls down to the top of the return plate 1104 and slides to the lower left. Then the staff can pick up the calendered material and repeatedly fill it into the top of the calendering device 5 to complete the repeated calendering and mixing processing of the material, so that the material is evenly mixed and dense inside. Then the staff can pull the pull rods 2206 on the front and rear sides outward, and the pull rods 2206 drive the triangular block 2202 to move outward. The triangular block 2202 moves outward to release the positioning of the triangular slider 2203. At this time, the return plate 1104 slides downward by itself under the action of gravity; After that, the staff again puts the material on the top of the calendering device 5, and then the calendered material moves downward in sheets. The material moves downward and is guided by the top angle of the blanking guide frame 1103 to slide to the left, and then touches the top of the feeding crawler 1304 downward, and then starts the driving motor 1401. The driving motor 1401 starts to drive the worm 1404 to rotate through the rotating shaft 1402. The rotation of the worm 1404 drives the transmission roller 1303 to rotate through the worm gear 1405. The rotation of the transmission roller 1303 drives the feeding crawler 1304 to roll. The rolling of the feeding crawler 1304 drives the material to move to the right. After the sheet of material moves to the right side of the main frame 41, the staff picks up the material and fixes it in the winding device; After that, the staff starts the servo motors 3101 on the front and rear sides. The servo motor 3101 starts and drives the worm 2 3104 to rotate through the rotating shaft 2 3102. The rotation of the worm 2 3104 drives the transmission gear 3203 to rotate through the worm gear 2 3201 and the rotating shaft 3202. The rotation of the transmission gear 3203 drives the sliding racks 3301 on the left and right sides to slide synchronously in opposite directions, wherein the sliding rack 3301 on the left side moves upward, and the sliding rack 3301 on the right side moves downward. The sliding rack 3301 slides through the moving slide bar 3302 to drive the lifting shaft 3303 to move. The movement of the lifting shaft 3303 drives the tensioning drum 3304 to move. The tensioning drums 3304 on the left and right sides move up and down respectively to extrude the material so that it stands suspended in the main frame 41. At this time, the discharge speed and the discharge speed below the calendering equipment 5 are fixed, and the different extrusion degrees of the tensioning drums 3304 on the upper and lower sides can perform different degrees of tensioning treatment on the material.
