Embodiment 1

[0041] Such as Figure 1-6 As shown, a breast roll with a built-in shaking device includes a breast roll body 1 , and a main shaft 2 is installed inside the breast roll body 1 ; the main shaft 2 runs through the breast roll body 1 . Shaking device and transmission mechanism are installed on the main shaft 2. The shaking device includes a first eccentric mass assembly 3 and the second eccentric mass assembly 4 which are arranged oppositely; Eccentric mass mechanism: each set of eccentric mass mechanisms includes eccentric mass 31 and outer rotor motor 32 . The outer rotor motor 32 refers to a motor whose shell rotates and the shaft is fixed. The outer rotor motor 32 is installed in the eccentric block 31, and the outer casing of the outer rotor motor 32 is connected with the eccentric block 31; when the outer rotor motor 32 is running, the outer rotor motor 32 drives the eccentric block 31 to rotate; the eccentric block 31 rotates produce centrifugal force. Since the two se...

Embodiment 2

[0055] This embodiment is substantially the same as the first embodiment, except that the transmission mechanism of this embodiment includes transmission bearings. The inner ring of the transmission bearing is fixedly connected with the main shaft. The outer ring of the transmission bearing is fixedly connected with the breast roll body. When the breast roll body rotates, the main shaft will not follow the breast roll body rotation. When the shaking device is running, when the main shaft vibrates axially, the main shaft transmits the axial centrifugal force to the breast roll body through the transmission bearing.

Abstract

The invention belongs to the technical field of papermaking equipment, and particularly relates to a breast roll with a built-in shaking device, which comprises a breast roll body and further comprises a main shaft mounted in the breast roll body, the shaking device is mounted on the main shaft, a transmission mechanism is mounted on the main shaft, axial vibration generated by the shaking deviceis transmitted to the breast roll body, the shaking device comprises a first eccentric block assembly and a second eccentric block assembly, each of the first eccentric block assembly and the second eccentric block assembly comprises two groups of eccentric block mechanisms which are oppositely arranged up and down, the eccentric block mechanism comprises an eccentric block and an outer rotor motor, the outer rotor motor is installed in the eccentric block, a shell of the outer rotor motor is connected with the eccentric block, when the outer rotor motor operates, the shell drives the eccentric block to rotate, and a centrifugal force is generated by rotation of eccentric block. By means of the unique design that the outer rotor motor is installed on the eccentric block, the size and the weight of the eccentric block assembly are greatly reduced, and the concept of zero space occupation of the shaking device is achieved.

Description

technical field [0001] The invention belongs to the technical field of papermaking equipment, and in particular relates to a breast roll with a built-in shaking device. Background technique [0002] At present, the shaking devices in the world are all installed on one side of the breast roll, and the breast roll is driven by the shaking rod. Therefore, the space for installing the shaking device must be reserved on the site. [0003] The shaking device is mainly used in paper mills, and the workshop space of paper mills is very crowded. Especially for the renovation project, there is no space reserved for the vibration installation, and it takes a lot of energy and money to renovate the workshop site to make room for the installation of the vibration device, which is very inconvenient. Traditional shaking devices such as Figure 7 As shown, the traditional shaking device (100) includes an eccentric mass assembly installed on the core frame (103), and the eccentric mass ass...
