Description

Technical Field

[0001] The utility model specifically relates to the technical field of shaft roll replacement, in particular to a lifting device for replacing shaft rolls of a corrugating machine. Background Art

[0002] The roller is an important part of the corrugator. It presses the base paper into a specific shape of corrugation through heating and pressure. It determines the shape, height and strength of the corrugation, which directly affects the quality of the corrugated board. Different rollers can produce different flute types according to production requirements, so the rollers need to be replaced during the processing and production process.

[0003] At present, when traditional shaft rollers are replaced, they are lifted and replaced manually. However, in special processing and production, the shaft rollers are large in size and heavy in weight, and cannot be lifted manually. With the improvement of technology, the shaft rollers with larger volume are replaced by hoisting. During the hoisting process, the shaft rollers may collide with adjacent shaft rollers, causing damage to the digital display on the surface of the shaft rollers, which may affect the quality of processing and production when used again. When corrugated paper is processed and produced, the production effect needs to be achieved through the cooperation between multiple shaft rollers. Therefore, when hoisting, the hoisting device may not be installed on the shaft rollers.

[0004] A search revealed that Chinese patent publication number CN202222037681.1 discloses a scissor-fork type lifting device, comprising a vehicle body having a hollow structure, an outer shell provided around the vehicle body, a traveling mechanism provided at the bottom of the vehicle body, a power mechanism provided on the inner side of one end of the vehicle body, a control mechanism provided on the inner side of the other end of the vehicle body, a scissor-fork type lifting mechanism provided in the middle of the vehicle body, a lifting platform installed on the top of the scissor-fork type lifting mechanism, a clamp provided on the upper part of the lifting platform, and a navigation assembly provided in the middle of the vehicle body. The scissor-fork type lifting mechanism comprises two symmetrically arranged scissor arm structures, a belt roller group, a belt reel, a motor, and a safety cylinder.

[0005] When the lifting device in the above patent is lifting, the cooperation between the inner scissor fork arm and the outer scissor fork arm enables the top lifting platform to move up and down effectively, thereby achieving the effect of overall lifting. However, in the corrugated machine, the distance between two adjacent shaft rollers is small. In this way, when lifting and replacing, the moving route of the lifting platform may be blocked, and the lifting and replacement of the shaft rollers cannot be effectively realized. Utility Model Content

[0006] The purpose of the utility model is to provide a lifting device for replacing the shaft rollers of a corrugator. In the device, two shaft rollers that cooperate with each other in the corrugator are lifted at the same time by a lifting component, so that the shaft roller that needs to be replaced is moved inside the device, so that when the shaft roller is replaced, it will not cause obstruction. When the shaft roller is moved out of the corrugator, the electric push cylinder in the replacement component drives the movable plate to rotate along the rotating shaft, so that the end of the movable plate where the shaft roller is installed is tilted upward, and the two shaft rollers that cooperate with each other are separated. In this way, collision between two adjacent shaft rollers is effectively avoided during replacement, and the quality of the shaft rollers is effectively guaranteed; so as to solve the problems of the above-mentioned background technology.

[0007] To achieve the above purpose, the present invention provides the following technical solutions:

[0008] A lifting device for replacing a corrugator shaft roll comprises a mounting assembly; the mounting assembly comprises a support plate; one side of the support plate is provided with two symmetrical side ears; side plates are fixedly mounted at both ends of the support plate; a driving shaft roller is mounted between the two side plates; a driving gear is fixedly mounted at one end of the driving shaft roller;

[0009] The bottom of the support plate is equipped with a lifting assembly; the lifting assembly includes a top plate; the top plate is fixedly installed with the support plate; the bottom of the top plate is fixedly installed on the top of the slide; a longitudinal slide rail is fixedly installed on one side of the slide; the longitudinal slide rail is slidably installed with the guide rail on one side of the side support plate;

[0010] As a further technical solution of the present invention, reinforcement plates are fixedly installed on both sides of the top of the slide; the reinforcement plates are fixedly installed to the top plate; a fixing frame is fixedly installed in the middle of the reinforcement plate on one side of the slide through a horizontal plate; a rotating wheel is movably installed at the bottom of the fixing frame through a rotating shaft;

[0011] As a further technical solution of the present invention, the rotating wheel is fitted with the lifting plate. The bottom of the lifting plate is slidably mounted on a transverse slide rail; the transverse slide rail is fixedly mounted on the bottom plate through a pad.

[0012] As a further technical solution of the present invention, the side of the jacking plate away from the reinforcing plate is fixedly installed with the push rod of the cylinder through a connecting plate; the cylinder is fixedly installed on one side of the L-shaped support plate; the bottom of the L-shaped support plate is fixedly installed with the bottom plate;

[0013] As a further technical solution of the present invention, a replacement assembly is also provided between the support plates; the replacement assembly includes an electric push cylinder fixedly mounted on the side ear of one side of the support plate; a movable plate is movably mounted on the inner side of the two side plates through a rotating shaft; a driven shaft is mounted on the end of the movable plate; a driven gear is fixedly mounted on one end of the driven shaft;

[0014] As a further technical solution of the present invention, the driven shaft is movably mounted on the movable plate via a buckle; the buckle is cooperatively mounted on the movable plate; the end of the movable plate away from the buckle is movably connected to the push rod of the electric push cylinder via a connecting rod;

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. In the present invention, when in use, the cylinder drives the lifting plate to move laterally along the transverse slide rail via the connecting plate. Since the top of the lifting plate is arranged in a stepped shape, the bottom of the rotating wheel contacts the lifting plate during the movement of the lifting plate, and the rotating wheel drives the reinforcing plate to move up and down via the fixing frame, thereby effectively adjusting the distance that the top plate drives the installation assembly to move, and realizing the overall removal of the installation assembly from the interior of the production equipment;

[0017] 2. In this utility model, during lifting, the reinforcement plate is fixed to the slide, and the longitudinal slide rail fixed on the side of the slide away from the fixed frame slides up and down along the guide rail on the side of the side support plate, thereby effectively ensuring the stability of the top plate during lifting;

[0018] 3. In the utility model, after the entire installation component is moved out of the equipment, one end of the movable plate is driven to move downward by the electric push cylinder installed at the bottom of the support plate. When one end of the movable plate moves downward, the movable plate rotates along the rotating shaft at the same time, so that the movable plate moves upward through the driven shaft rod installed by the buckle, thereby realizing the separation between the driven shaft rod and the active shaft roller, and then the buckle at the end of the movable plate is opened to realize the replacement of the driven shaft rod. The distance between the driven shaft rod and the active shaft roller is large, which effectively avoids collisions. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The bottom of the support plate 10 is fitted with a lifting assembly 3; the lifting assembly 3 includes a top plate 33; the top plate 33 is fixedly mounted to the support plate 10; the bottom of the top plate 33 is fixedly mounted on the top of the slide 312; a longitudinal slide rail 311 is fixedly mounted on one side of the slide 312; the longitudinal slide rail 311 is slidably mounted on the guide rail 310 on one side of the side support plate 32;

[0032] Reinforcement plates 39 are fixedly installed on both sides of the top of the slide 312; the reinforcement plates 39 are fixedly installed with the top plate 33; a fixing frame 36 is fixedly installed in the middle of the reinforcement plate 39 on one side of the slide 312 through a horizontal plate; a rotating wheel 37 is movably installed at the bottom of the fixing frame 36 through a rotating shaft.

[0033] By adopting the above technical solution, when in use, the cylinder 31 drives the lifting plate 35 to move laterally along the transverse slide rail 34 through the connecting plate 313. Since the top of the lifting plate 35 is arranged in a stepped shape, the bottom of the rotating wheel 37 contacts the lifting plate 35 during the movement of the lifting plate 35, so that the rotating wheel 37 drives the reinforcing plate 39 to move up and down through the fixing frame 36, thereby effectively adjusting the distance that the top plate 33 drives the installation assembly 1 to move, and realizing the overall removal of the installation assembly 1 from the interior of the production equipment;

[0034] The rotating wheel 37 is fitted with the lifting plate 35. The bottom of the lifting plate 35 is slidably mounted on the transverse slide rail 34; the transverse slide rail 34 is fixedly mounted on the bottom plate 30 through a pad.

[0035] In this embodiment, the side of the lifting plate 35 away from the reinforcing plate 39 is fixedly mounted to the push rod of the cylinder 31 through the connecting plate 313; the cylinder 31 is fixedly mounted on one side of the L-shaped support plate 38; the bottom of the L-shaped support plate 38 is fixedly mounted to the bottom plate 30;

[0036] By adopting the above technical solution, during lifting, the reinforcing plate 39 is fixedly mounted on the slide 312, and the longitudinal slide rail 311 fixedly mounted on the side of the slide 312 away from the fixed frame 36 slides up and down along the guide rail 310 on the side of the side support plate 32, thereby effectively ensuring the stability of the top plate 33 during the lifting process;

[0037] In this embodiment, a replacement assembly 2 is further provided between the support plates 10; the replacement assembly 2 includes an electric push cylinder 23 fixedly mounted on the side ear of one side of the support plate 10; a movable plate 21 is movably mounted on the inner side of the two side plates 11 through a rotating shaft 24; a driven shaft 20 is mounted on the end of the movable plate 21; and a driven gear 25 is fixedly mounted on one end of the driven shaft 20;

[0039] By adopting the above technical solution, after the installation component 1 is moved out of the equipment as a whole, the electric push cylinder 23 installed at the bottom of the support plate 10 drives one end of the movable plate 21 to move downward. When one end of the movable plate 21 moves downward, the movable plate 21 rotates along the rotating shaft 24 at the same time, so that the movable plate 21 moves upward with the installed driven shaft rod 20 through the buckle 26, thereby realizing separation from the active shaft roller 14, and then the buckle 26 at the end of the movable plate 21 is opened to realize replacement of the driven shaft rod 20.

Since the top of the lifting plate 35 is arranged in a stepped shape, the bottom of the rotating wheel 37 contacts the lifting plate 35 during the movement of the lifting plate 35, so that the rotating wheel 37 drives the reinforcing plate 39 to move up and down through the fixing frame 36, thereby effectively adjusting the distance that the top plate 33 drives the installation assembly 1 to move, and realizing the overall removal of the installation assembly 1 from the interior of the production equipment;

[0041] During lifting, the reinforcing plate 39 is fixedly mounted on the slide 312, and the longitudinal slide rail 311 fixedly mounted on the side of the slide 312 away from the fixing frame 36 slides up and down along the guide rail 310 on the side of the side support plate 32, thereby effectively ensuring the stability of the top plate 33 during the lifting process;

[0042] After the installation component 1 is moved out of the equipment as a whole, the electric push cylinder 23 installed at the bottom of the support plate 10 drives one end of the movable plate 21 to move downward. When one end of the movable plate 21 moves downward, the movable plate 21 rotates along the rotating shaft 24 at the same time, so that the movable plate 21 moves upward with the installed driven shaft rod 20 through the buckle 26, thereby achieving separation from the active shaft roller 14. Then the buckle 26 at the end of the movable plate 21 is opened to replace the driven shaft rod 20. The distance between the driven shaft rod 20 and the active shaft roller 14 is large, which effectively avoids collisions.
