Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical packaging technology, and in particular to a composite rigid sheet flattening device. Background Technology

[0002] Aluminum composite rigid sheets are generally used in the production of drug capsules. For the encapsulation of drug capsule tablets, the aluminum composite rigid sheets need to be flat when they are adhered to the capsule plate. However, wrinkles inevitably form on the aluminum composite rigid sheets during the production process, which affects the adhesion of the aluminum composite rigid sheets to the capsule plate. Before the capsules are encapsulated, the aluminum composite rigid sheets need to be flattened. The current method of flattening aluminum composite rigid sheets is to use a single pressure roller to repeatedly squeeze and roll on the aluminum composite sheet to flatten it. However, this method has low flattening efficiency.

[0003] A search revealed a Chinese patent document (authorization announcement number CN218395379U) entitled "An Aluminum Composite Rigid Sheet Flattening Device," belonging to the field of aluminum composite rigid sheet processing technology. The device includes a processing box, with a motor connected to the upper center of the box. A drive arm, penetrating the processing box and located inside it, is connected to the motor. One end of the drive arm is connected to a flattening component that slides inside the processing box. The drive arm drives the flattening component to reciprocate left and right to flatten the aluminum composite rigid sheet. While this device reduces manual operation time and increases efficiency, and solves the problem of repeatedly rolling the aluminum composite rigid sheet under a single roller, in actual use, the mechanical mechanism driving the single roller to reciprocate roll the aluminum sheet is inefficient, and the connection between the mechanical structure and the single roller reciprocating structure suffers excessive wear, leading to a reduced lifespan of the device. Therefore, a composite rigid sheet flattening device is urgently needed to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a composite rigid sheet flattening device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a composite rigid sheet flattening device, comprising a base plate for mounting the composite rigid sheet flattening device and an extrusion roller for flattening aluminum composite rigid sheets, wherein mounting plates are symmetrically fixedly mounted on the top surface of the base plate, and a horizontal plate is fixedly mounted between the two mounting plates.

[0006] Multiple hydraulic cylinders are fixedly installed at the bottom of the horizontal plate, and a pressure plate is fixedly installed between the telescopic ends of the multiple hydraulic cylinders. Multiple flattening rollers are rotatably installed at the bottom of the pressure plate.

[0007] Two vertical plates are symmetrically fixedly installed on the top surface of the base plate. Each of the two vertical plates has a vertical groove on its opposite side. A slider is slidably installed inside each of the two vertical grooves. The extrusion roller is rotatably installed between the two sliders.

[0008] A spring is fixedly installed on the upper end of the inner wall of the vertical groove, and the bottom of the spring is fixedly connected to the top surface of the slider.

[0009] A fixed roller is rotatably mounted below the opposite side of the two vertical plates.

[0010] Preferably, a vertical rod is fixedly installed on the inner wall of the vertical groove, and a through hole is opened on the side wall of the slider in the longitudinal direction.

[0011] Preferably, the vertical rod fixedly installed in the vertical groove is slidably sleeved into the through hole longitudinally opened on the slider.

[0012] Preferably, two limiting blocks are symmetrically fixedly installed on the side wall of the slider, and two limiting grooves are symmetrically opened on the inner wall of the vertical groove.

[0013] Preferably, the two limiting blocks fixedly installed on the side wall of the slider are slidably connected to the inside of the two limiting grooves opened on the inner wall of the vertical groove.

[0014] Preferably, the top surface of the base plate is provided with multiple strip grooves, and each of the multiple strip grooves is rotatably installed with a pressure roller.

[0015] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0016] This composite rigid sheet flattening device benefits from the structure of horizontal plate, hydraulic cylinder, pressure plate and flattening roller. When the aluminum composite rigid sheet moves between the bottom plate and multiple flattening rollers, multiple hydraulic cylinders are activated simultaneously to push the pressure plate fixedly installed at its telescopic end to move downward. The pressure plate will drive the multiple flattening rollers installed at its bottom to move downward and repeatedly roll the aluminum composite rigid sheet, thereby squeezing the aluminum composite rigid sheet flat.

[0017] This composite rigid sheet flattening device, thanks to the setting of vertical groove, slider, extrusion roller and spring, first places the aluminum composite rigid sheet between the extrusion roller and the fixed roller. At this time, the spring will push the slider fixedly installed at its end to move downward. The slider will drive the extrusion roller to extrude the aluminum composite rigid sheet. The aluminum composite rigid sheet is initially extruded and flattened by the extrusion roller and the fixed roller.

[0018] This composite rigid sheet flattening device benefits from the setting of multiple pressure rollers on the top surface of the base plate. The pressure rollers and the flattening rollers are in contact with each other, and the contact surface between the pressure rollers and the flattening rollers is small but the pressure is large. Therefore, it can further improve the flattening effect of the aluminum composite rigid sheet and prevent wrinkles from occurring.

[0019] Compared with existing technologies, this composite rigid sheet flattening device can effectively improve the flattening efficiency of aluminum composite rigid sheets. Attached Figure Description

[0030] like Figures 1 to 4The main structure of the composite hard sheet leveling device shown is a base plate 1 for mounting the composite hard sheet leveling device and an extrusion roller 10 for leveling aluminum composite hard sheets. The top surface of the base plate 1 is symmetrically fixedly mounted with an mounting plate 2. A horizontal plate 3 is fixedly mounted between the two mounting plates 2. Multiple hydraulic cylinders 4 are fixedly mounted at the bottom of the horizontal plate 3. A pressure plate 5 is fixedly mounted between the telescopic ends of the multiple hydraulic cylinders 4. Multiple flattening rollers 6 are rotatably mounted at the bottom of the pressure plate 5. The flattening rollers 6 are mounted at the bottom of the flattening rollers 6 through two mounting blocks. Multiple flattening rollers 6 are set to achieve repeated rolling of the aluminum composite hard sheet, thereby further improving the leveling effect of the aluminum composite hard sheet.

[0031] Traction rollers 16 are symmetrically installed on the top surface of the base plate 1 away from the vertical plate 7, which pulls the aluminum composite hard sheet between the two traction rollers 16, thereby effectively pulling the aluminum composite hard sheet.

[0032] Thanks to the structure of the horizontal plate 3, hydraulic cylinder 4, pressure plate 5 and pressing roller 6, when the aluminum composite hard sheet moves between the bottom plate 1 and multiple pressing rollers 6, multiple hydraulic cylinders 4 are activated simultaneously to push the pressure plate 5, which is fixedly installed at its telescopic end, to move downward. The pressure plate 5 will drive the multiple pressing rollers 6 installed at its bottom to move downward and repeatedly roll the aluminum composite hard sheet, thereby squeezing the aluminum composite hard sheet flat.

[0033] Two vertical plates 7 are symmetrically fixedly installed on the top surface of the base plate 1. Each of the two vertical plates 7 has a vertical groove 8 on one side opposite to the other. A slider 9 is slidably installed inside each of the two vertical grooves 8. The extrusion roller 10 is rotatably installed between the two sliders 9. The size of the slider 9 slidably installed inside the vertical groove 8 is slightly smaller than the internal size of the vertical groove 8, so that the inner wall of the slider 9 slides against the inside of the vertical groove 8, thereby limiting the sliding direction of the slider 9 and further improving the stability of the slider 9 when sliding.

[0034] A spring 12 is fixedly installed on the upper end of the inner wall of the vertical groove 8. The bottom of the spring 12 is fixedly connected to the top surface of the slider 9. A fixed roller 11 is rotatably installed on the lower side of the two vertical plates 7 on opposite sides. Thanks to the structure of the vertical groove 8, slider 9, extrusion roller 10 and spring 12, the aluminum composite hard sheet is first placed between the extrusion roller 10 and the fixed roller 11. At this time, the spring 12 will push the slider 9 fixedly installed at its end to move downward. The slider 9 will drive the extrusion roller 10 to extrude the aluminum composite hard sheet. The aluminum composite hard sheet is initially extruded and flattened by the extrusion roller 10 and the fixed roller 11.

[0035] A vertical rod 13 is fixedly installed on the inner wall of the vertical groove 8. A through hole is opened on the side wall of the slider 9. The vertical rod 13 fixedly installed in the vertical groove 8 is slidably sleeved into the through hole opened on the slider 9. The vertical rod 13 can effectively limit the sliding direction of the slider 9 and further improve the stability of the slider 9 when sliding longitudinally.

[0036] Two limiting blocks 14 are symmetrically fixedly installed on the side wall of the slider 9, and two limiting grooves are symmetrically opened on the inner wall of the vertical groove 8. The two limiting blocks 14 fixedly installed on the side wall of the slider 9 are slidably connected to the inside of the two limiting grooves opened on the inner wall of the vertical groove 8. The two limiting blocks 14 can effectively limit the sliding direction of the slider 9.

[0037] Multiple strip grooves are provided on the top surface of the base plate 1. Each of the multiple strip grooves has a pressure roller 15 rotatably installed inside. Thanks to the multiple pressure rollers 15 on the top surface of the base plate 1, the pressure rollers 15 and the flattening rollers 6 are in contact with each other. The contact area between the pressure rollers 15 and the flattening rollers 6 is small but the pressure is strong. Therefore, the flattening effect of the aluminum composite hard sheet can be further improved and wrinkles can be prevented.

[0038] Working principle

[0039] In use, the aluminum composite sheet flattening device first places the aluminum composite sheet to be flattened between the extrusion roller 10 and the fixed roller 11. At this time, the spring 12 in the vertical groove 8 will push the slider 9 fixedly installed at its end to move downward. The two sliders 9 drive the extrusion roller 10 to move downward, thereby initially extruding and flattening the aluminum composite sheet. Then, the aluminum composite sheet is pulled between the flattening roller 6 and the pressure roller 15, and then the aluminum composite sheet is pulled between the two traction rollers 16. At this time, multiple hydraulic cylinders 4 are activated. The telescopic ends of the multiple hydraulic cylinders 4 push the pressure plate 5 fixedly installed at its end to move downward. The pressure plate 5 drives the multiple flattening rollers 6 installed at its end to repeatedly extrude and flatten the aluminum composite sheet, thereby further improving the flattening effect of the aluminum composite sheet.
