Description

Technical Field

[0001] This utility model relates to an electric ink tray lifting device, belonging to the field of printing machinery technology. Background Technology

[0002] Traditional printing presses typically use manual hand-cranking for raising and lowering the ink roller. Due to the specific structural design of printing presses, the ink roller is usually positioned quite low, requiring operators to bend over while simultaneously raising and lowering it and cleaning the ink roller. This usually requires multiple operators, increasing labor costs and increasing the risk of accidents due to improper operation. Furthermore, the frequent ink roller cleaning and prolonged bending over can easily lead to occupational diseases for operators. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides an electric ink tray lifting device that automates the lifting of the ink tray and precisely controls its stroke.

[0004] To achieve this objective, the structure adopted in this utility model is as follows: an electric ink tray lifting device, including a main shaft, a motor reducer connected to the main shaft, one or more gear seats fitted on the main shaft, a gear fitted inside the gear seat and mounted on the main shaft, a rack next to each gear seat, the rack being perpendicular to the main shaft and meshing with the gear inside the gear seat, an ink tray holder connected to the top of each rack, and the gear seats and the motor reducer being mounted on the printing press frame.

[0005] A switch bracket is provided on one or more gear seats, and a first limit switch is provided on the switch bracket, with the first limit switch facing the ink tray holder.

[0006] The motor reducer is mounted on the motor frame, one end of which is equipped with a second limit switch, and a screw shaft is mounted on the main shaft.

[0007] The screw shaft is connected to the end of the main shaft via a limit switch arm. The limit switch arm is connected to the main shaft via a bearing. A crescent groove is provided on the side of the limit switch arm, and a pin is provided in the crescent groove. The pin is connected to the main shaft.

[0008] The limit switch arm is provided with multiple connection holes, and the screw shaft is connected to one of the connection holes.

[0009] A sleeve is provided on the gear seat, and the rack is inserted inside the sleeve.

[0010] A reinforcing plate is provided between the rack and the ink tray holder.

[0011] Its beneficial effects are: the structure of this utility model is reasonable and ingenious. The main shaft rotates under the drive of the motor reducer, which causes the rack to drive the ink tray frame to move up and down automatically. There is no need for manual hand cranking. The operator only needs to wipe the ink roller. At the same time, when it is raised and lowered to a certain height, the operator does not need to bend over to work. Attached Figure Description

[0012] This utility model will be described by way of example and with reference to the accompanying drawings, wherein:

[0013] Figure 1 This is a three-dimensional structural diagram of the present invention;

[0014] Figure 2 This is a structural diagram of the limit switch swing arm. Detailed Implementation

[0015] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0016] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used solely for the convenience of describing this utility model and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; a fixed connection can be welding or adhesive bonding. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0018] like Figure 1The electric ink tray lifting device shown includes a main shaft 2, which is connected to a motor reducer 1 and driven to rotate. One or more gear seats 3 are mounted on the main shaft 2, with gears mounted inside the gear seats 3. A rack 4 is located next to each gear seat 3, perpendicular to the main shaft 2, and meshes with the gears inside the gear seats 3. When the main shaft 2 rotates, the rack 4 rises and falls under the action of the gears. An ink tray holder 5 is connected to the top of each rack 4, and the ink tray 5 is connected to the ink tray holder 5. The gear seats 3 and the motor reducer 1 are mounted on the printing press frame. The motor reducer 1 is controlled remotely to achieve the electric lifting of the rack 4, saving manpower. Operators only need to wipe the ink rollers, improving safety, and the raised ink tray operation avoids the occupational disease caused by prolonged bending.

[0019] One or more gear seats 3 are equipped with a switch bracket 6, and a first limit switch 10 is mounted on the switch bracket 6, with the first limit switch 10 facing the ink tray holder 5. When the ink tray holder 5 touches the first limit switch 10, the first limit switch 10 controls the motor reducer 1 to stop running. The switch bracket 6 encloses the first limit switch 10 in the center, with an opening at the top. When the ink tray holder 5 is lowered, it covers the top of the switch bracket 6 to prevent the first limit switch 10 from being exposed and accidentally activated.

[0020] The motor reducer 1 is mounted on the motor frame 9, and a second limit switch 7 is mounted on one end of the motor frame 9. A screw shaft 8 is mounted on the main shaft 2.

[0021] like Figure 2 As shown, the screw shaft 8 is connected to the end of the main shaft 2 via a limit switch arm 11. The limit switch arm 11 is connected to the main shaft 2 via a bearing. A crescent groove is provided on the side of the limit switch arm 11, and a pin 12 is provided in the crescent groove. The pin 12 is connected to the main shaft 2. In the stopped state, the screw shaft 8 hangs down naturally. When the main shaft 2 rotates, the pin 12 rotates accordingly. When the pin 12 rotates to the edge of the crescent groove, it drives the limit switch arm 11 to rotate together. At this time, the screw shaft 8 also rotates. When the screw shaft 8 touches the second limit switch 7, the ink disc holder 5 rises to the highest point, and the second limit switch 7 controls the motor reducer 1 to stop.

[0022] The limit switch arm 11 is provided with multiple connection holes, and the screw shaft 8 is connected to one of the connection holes.

[0023] A sleeve is provided on the gear seat 3, and the rack 4 is inserted into the sleeve to ensure the meshing of the rack with the gear inside the gear seat 3 and to avoid misalignment and slippage.

[0024] A reinforcing plate is provided between the rack 4 and the ink tray frame 5. The reinforcing plate is located at the bottom of the ink tray frame 5 and provides reinforcement and support to the ink tray frame 5, ensuring the load-bearing capacity of the ink tray frame 5.

[0025] Based on the above description and inspired by this utility model, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
