Description

Technical Field

[0001] The utility model relates to the technical field of machinery, and more specifically, to a pressing roller motor mounting and fixing device and a stem pressing machine. Background Art

[0002] Currently, stem presses are widely used in tobacco production processes. These machines are primarily deployed before the cutting process in the tobacco processing line, flattening the steamed tobacco stems for subsequent processing. The front and rear rollers of the stem press are made of chilled alloy cast iron, offering high surface hardness and excellent wear resistance. The rear roller is fixed to the frame with bearings, while the front roller is mounted on guide slides on either side of the frame via bearing blocks. The gap between the rollers can be adjusted as needed with the movement of the slides. During operation, the rollers, driven by two reducers, rotate in opposite directions to flatten the tobacco stems. The gap between the rollers can be adjusted within a range of 0.5 to 5.0 mm. The rolling force is provided by a hydraulic system, and a photoelectric detector is installed between the two rollers. When a large amount of tobacco is fed into the rollers, blocking the light path, the blocked tobacco stems block the optical path. A photoelectric signal triggers the hydraulic system to retract the front roller, creating a gap of approximately 50 mm between the rollers to allow the blocked tobacco stems to be discharged.

[0003] During the design and installation process of the stem press roller motor, different equipment manufacturers have adopted different design solutions to achieve the installation of the stem press roller motor, ultimately all of which can meet the process performance requirements of the actual production process. A stem press roller motor mounting and fixing device, based on the design and installation structural characteristics of the stem press roller motor, utilizes the double shaft reversing function of the stem press roller motor mounting and fixing device to achieve a vertical mounting and fixing method for the stem press roller motor within the available equipment space.

[0004] Therefore, how to provide a pressing roller motor mounting and fixing device and a stem pressing machine has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0056] The middle block 15 and the first plate 11 and the second plate 12 may be an integral structure, or the three parts may be fastened together by bolts;

[0057] The bottom of the intermediate block 15 begins to have a threaded hole, and the intermediate block is fixed to the rack connection base 3 by passing the fixing bolt 100 through the bottom plate hole 33 on the rack connection base 3. In order to tighten the connection, there can be two bottom plate holes 33.

[0058] like Figure 4 As shown, the rack connection base 3 is a right-angle structure, including a bottom plate 31, a vertical plate 32 and a bottom plate hole 33; the bottom plate 31 and the vertical plate 32 are arranged vertically; a bottom plate hole 33 is provided on the bottom plate 31, and the rack connection base 3 also includes a reinforcing plate 34, which is a right-angled triangle plate, one right-angled side is welded to the vertical plate 32, and the other right-angled side is welded to the bottom plate 31.

This ensures a certain degree of variable adjustment function when adjusting the roller gap and retracting the roller. The multi-point adjustment capability within a certain distance allows the horizontal position to change with the roller, meeting production requirements.

[0063] According to a second aspect of the present invention, a stem pressing machine is provided, comprising the pressing roller motor mounting and fixing device described in any one of the first embodiments. The working principle and installation steps are as follows:

[0064] The frame connection base is positioned appropriately on the stem press frame as needed. It is connected to the machine frame using mounting bolts through the four mounting holes on the frame connection base, establishing the base installation position for the entire unit. The pivot-type through-hole locating block is bolted to the frame connection base via the locating block mounting plate. The pivot-type through-hole locating block utilizes two holes on the locating block mounting plate for hole-to-shaft connection. The locating bolts are secured using compression nuts through the through-holes on the pivot-type through-hole locating block. A number of locating adjustment shims can be added as needed during the connection process. These locating adjustment shims ensure installation accuracy and reduce vibration and impact on the entire unit during operation of the roller motor, thereby increasing the equipment's service life. The upper end of the locating bolts connects to the shaped locating arm using a threaded hole, and a compression nut is used to secure and secure the connection. The other end of the shaped locating arm features two holes at its open end for reversing connection with the shaped locating arm's shaft and the motor baseplate. A retaining ring is used to prevent disengagement. The shaped positioning arm and the motor base plate form a rotating shaft connection via the shaped positioning arm's rotating shaft, enabling rotation and displacement within a specific spatial range. The motor mounting base plate is securely connected to the stem press motor via four fastening bolts. Designed from carbon steel, the motor mounting base plate features a top plate with reinforced side supports for the shaft sleeve and a bottom plate fixed to it, further enhancing its overall design strength and operational stability. The entire device utilizes design features and mechanical structure variations, ingeniously designed and assembled using multiple mechanical components. The shaped positioning arm's rotating shaft connects to the motor base plate, and the axial connection is secured by a through-hole positioning block using two holes in the positioning block's mounting plate. This creates a vertical linkage mechanism centered around the equipment mounting frame. The entire device can vary its displacement around this center, ensuring variable adjustment of the roller gap and roll retraction. It also features multi-point adjustment capabilities within a certain distance, allowing it to follow the horizontal position of the rollers to meet production requirements.

[0065] In summary, the device disclosed herein is used to mount and secure the motor of a stem pressing roller in the silk production process. It provides for transitioning and changing the mounting orientation of the motor to meet the requirements of equipment installation and use. This device is simple and effective in design, easy to install and maintain, and has already been successfully applied to some related equipment.
