Description

Technical Field

[0001] This utility model relates to the field of rotary machine technology, specifically to a rotary machine roller positioning bracket. Background Technology

[0002] A rotary printing press, also known as a rotary printing press, is a machine in which the image to be printed is bent around a cylinder. It can print on a variety of substrates, including paper, cardboard and plastic. The substrate can be fed individually or printed by rewinding the printing press on a continuous series of rollers, and can be further modified as needed (such as die-cutting, varnishing, embossing).

[0003] Currently, rotary presses are widely used in printing, packaging, and other industries. The precise positioning of their rollers directly affects the processing quality and production efficiency of products. However, existing rotary press roller positioning brackets have many shortcomings in use: for example, roller adjustment is inconvenient. When the roller position needs to be adjusted according to different processing requirements, the existing bracket adjustment process is complicated, cumbersome, and consumes a lot of time and manpower, reducing production efficiency. Furthermore, they lack versatility. One type of bracket is often only suitable for a specific type of roller. When changing the roller model, the entire bracket needs to be replaced, increasing production costs. Therefore, it is urgent to design a rotary press roller positioning bracket to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a roller positioning bracket for a rotary machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A roller positioning bracket for a rotary machine includes a U-shaped frame. Movable slots are provided on both sides of the U-shaped frame near the corners, and lifting sleeves are movably installed on the inner walls of the movable slots. A lifting mechanism for adjusting the height of the two lifting sleeves is provided on the U-shaped frame, and mounting components are provided on the inner walls of the lifting sleeves. A roller body is positioned between the two mounting components. Each mounting component includes a rotating shaft rotatably connected to the inner wall of the lifting sleeve via bearings, and a mounting cylinder is fixed to one end of each rotating shaft. Mounting shafts inserted into the mounting cylinders are fixedly installed at both ends of the roller body, and disassembly / assembly parts are provided on the mounting cylinders and mounting shafts.

[0007] Furthermore, the disassembly component includes a slot formed on one side of the top of the mounting cylinder, and a clamping hoop is fitted between the inner wall of the slot and the outer wall of the mounting shaft. Multiple mounting holes are formed on both the clamping hoop and the mounting cylinder. Multiple reinforcing holes are formed on the mounting shaft, and the positions of the mounting holes correspond to the positions of the reinforcing holes. Mounting screws are inserted through the inner walls of the mounting holes and the inner walls of the reinforcing holes, and nuts are screwed to the bottom of each mounting screw.

[0008] Furthermore, the lifting mechanism includes a cavity set inside the U-shaped frame, and a central hole is opened in the middle of the cavity. A threaded rod is rotatably connected to the inner wall of the central hole through a bearing. A forward and reverse motor for driving the threaded rod to rotate is fixedly installed on the top of the U-shaped frame. Both ends of the bottom of the cavity are provided with inlets and outlets communicating with the movable slot. A U-shaped seat is screwed onto the threaded rod. The bottom ends of the U-shaped seat pass through the inlet and outlet and are inserted into the movable slot. The top of the two lifting sleeves are fixed with lifting seats, and both lifting seats and the bottom ends of the U-shaped seats are provided with buffer components.

[0009] Furthermore, the buffer assembly includes buffer holes at both ends of the bottom of the U-shaped seat, and a T-shaped post is fixedly inserted into the buffer hole at the top of the lifting seat. An airbag is fixedly installed at the top of the T-shaped post and the top of the buffer hole, and a spring is fixedly installed at the bottom of the T-shaped post near the corner and the bottom inner wall of the buffer hole.

[0010] Furthermore, guide holes are provided on both sides of the top of the U-shaped seat, and a guide rod passing through the guide hole is fixed to the inner wall of the cavity.

[0011] Furthermore, guide grooves are provided on both inner walls of the movable groove, and guide seats that are slidably disposed in the guide grooves are fixed on both outer walls of the lifting sleeve.

[0012] Furthermore, ear seats are fixed on both sides of the bottom of the U-shaped frame, and a transmission gear is fixedly installed on the other end of one of the rotating shafts.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this utility model, the lifting mechanism of the bracket uses a forward and reverse motor as the power source to drive the threaded rod to rotate, thereby driving the U-shaped seat to move up and down. Then, through the buffer component, the lifting sleeve and the roller body are driven to lift up and down synchronously. This process does not require complicated operation. The roller height can be adjusted by the motor alone, which solves the problem of the traditional bracket adjustment process being cumbersome, time-consuming and labor-intensive. It can quickly adapt to different processing needs and significantly improve production efficiency.

[0015] In this invention, the design of the disassembly and assembly parts in the installation assembly makes the connection between the roller body and the mounting cylinder more flexible. By using the cooperation of clamping clamps, mounting holes, reinforcing holes and mounting screws, different models of rollers can be installed securely. Only the connection method of the disassembly and assembly parts needs to be adjusted according to the specifications of the roller's mounting shaft. There is no need to replace the entire bracket, which greatly improves the adaptability of the bracket to different models of rollers and reduces equipment replacement costs.

[0025] Specifically, the lifting mechanism 7 includes a cavity 75 disposed within the U-shaped frame 1, with a central hole 76 at the center of the cavity 75. A threaded rod 712 is rotatably connected to the inner wall of the central hole 76 via bearings. A forward / reverse motor 71 for driving the threaded rod 712 is fixedly mounted on the top of the U-shaped frame 1. Both ends of the bottom of the cavity 75 have inlet / outlet 77 communicating with the movable slot 10. A U-shaped seat 72 is screwed onto the threaded rod 712. The bottom ends of the U-shaped seat 72 pass through the inlet / outlet 77 and insert into the movable slot 10. Lifting seats 74 are fixed to the top of both lifting sleeves 8, and buffer assemblies are provided at both ends of the bottom of the U-shaped seat 72 for each lifting seat 74. The buffer assemblies include buffer holes 78 at both ends of the bottom of the U-shaped seat 72. A T-shaped post 710 is fixed at the top and inserted into the buffer hole 78. An airbag 79 is fixedly installed at the top of the T-shaped post 710 and the top of the buffer hole 78. A spring 711 is fixedly installed at the bottom of the T-shaped post 710 near the corner and the bottom inner wall of the buffer hole 78. Guide holes are opened on both sides of the top of the U-shaped seat 72, and a guide rod 73 passing through the guide hole is fixed on the inner wall of the cavity 75. The forward and reverse motor 71 in the lifting mechanism 7 drives the threaded rod 712 to rotate in the center hole 76, so that the U-shaped seat 72 screwed on the threaded rod 712 moves up and down along the guide rod 73, thereby facilitating the adjustment of the height of the roller body 5. In the buffer assembly, the T-shaped post 710 slides in the buffer hole 78, and the airbag 79 and spring 711 can buffer the impact force during the lifting process.

[0026] Specifically, guide grooves 11 are provided on both inner walls of the movable groove 10, and guide seats 9 are fixed on both outer walls of the lifting sleeve 8 and are slidably disposed in the guide grooves 11. The sliding action of the guide seats 9 in the guide grooves 11 ensures the stability of the lifting sleeve 8.

[0027] Specifically, ear seats 2 are fixed on both sides of the bottom of the U-shaped frame 1, and a transmission gear 6 is fixedly installed on the other end of one of the rotating shafts 43. The ear seats 2 facilitate the fixed installation of the entire positioning bracket on the rotating machine, and the transmission gear 6 is connected to the power source of the rotating machine to ensure that the roller body 5 rotates synchronously with the power source of the rotating machine.

[0028] The working principle of this utility model is as follows: First, the entire positioning bracket is fixedly installed on the rotary machine through the ear seat 2, and the transmission gear 6 is connected to the power source of the rotary machine for transmission.

[0029] In terms of roller installation and fixing, the mounting shafts 44 at both ends of the roller body 5 are inserted into the mounting cylinder 41, the clamping hoop 42 fits the slot 45 of the mounting cylinder 41 and the outer wall of the mounting shaft 44, and after the mounting hole 46 is aligned with the reinforcing hole 47, the mounting screw 48 is inserted and the nut is screwed on to fix the roller body 5 to the mounting assembly 4. The rotating shaft 43 of the mounting assembly 4 is connected to the inner wall of the lifting sleeve 8 through the bearing, and with the help of the transmission gear 6, the roller body 5 is ensured to rotate synchronously with the power source of the rotary machine.

[0030] During height adjustment, the forward and reverse motor 71 of the lifting mechanism 7 starts, driving the threaded rod 712 to rotate in the center hole 76, causing the U-shaped seat 72 screwed onto the threaded rod 712 to move up and down along the guide rod 73. The bottom ends of the U-shaped seat 72 pass through the inlet and outlet 77 and enter the movable groove 10, driving the lifting sleeve 8 to move synchronously through the buffer assembly. In the buffer assembly, the T-shaped column 710 slides in the buffer hole 78. The air bag 79 and the spring 711 can buffer the impact force during the lifting process. When the lifting sleeve 8 moves, the guide seat 9 on its outer wall slides along the guide grooves 11 on both sides of the movable groove 10, thereby realizing the height adjustment function of the roller body 5.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
