Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, specifically a slip differential shaft unloading device. Background Technology

[0002] The differential shaft consists of a shaft center, differential rings, an air pressure system, and an adjustment device. Each differential ring can rotate independently. When the shaft center rotates in one direction, the corresponding differential ring is locked, causing it to rotate in the same direction as the shaft center. However, when a certain tension is reached, the differential ring can maintain a constant tension by slipping. When the shaft center rotates in another direction, the differential ring is released from the shaft center and does not rotate with the shaft center, thus forming a loose state.

[0003] Slip shafts are typically used in printing equipment on multi-segmented rolls. When removing these rolls, repeated rotation and unloading actions are required. Since the shaft is not powered to rotate, manual rotation is needed when removing and installing the rolls, which can easily lead to problems such as the roll getting stuck, resulting in time-consuming and labor-intensive unloading. Summary of the Invention

[0004] The purpose of this utility model is to provide a slip differential shaft unloading device, including a shaft 13 and a slip differential ring 5 disposed on the shaft 13 for supporting fixed plates 1 disposed opposite to each other at both ends of the shaft 13. The device is characterized by further including an unloading drive transmission unit that drives the shaft 13 to rotate in the direction of loosening from the slip differential ring 5.

[0005] Preferably, the free end of the fixed plate 1 on one side is provided with a receiving frame 11; it also includes a bearing seat 2 disposed at one end of the shaft 13; a pin for rotatably connecting the bearing seat 2 and the receiving frame 11; the unloading drive transmission unit includes: a fixed bracket 14 connected to the bearing seat 2; a motor 7 disposed on the fixed bracket 14; a first gear 8 disposed on the output shaft of the motor 7; a second gear 6 disposed on the fixed bracket 14 and meshing with the first gear 8; a third gear 12 disposed on the fixed bracket 14 and meshing with the second gear 6; the third gear 12 meshing with a fourth gear 9 on the shaft 13.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1 Please see Figure 1-6 This embodiment provides a slip differential shaft unloading device, including a shaft 13 and a slip differential ring 5 disposed on the shaft 13 for supporting fixed plates 1 disposed opposite to both ends of the shaft 13, and also includes an unloading drive transmission unit for driving the shaft 13 to rotate in the direction of loosening from the slip differential ring 5.

[0020] Because of the addition of an unloading drive transmission unit that independently drives the shaft to rotate in the relaxation direction, the shaft can be loosened from the slip ring during unloading, making it easy to remove the material roll and saving time and effort.

[0021] Preferably, the free end of the fixed plate 1 on one side is provided with a receiving frame 11; it also includes a bearing seat 2 disposed at one end of the shaft 13; and a pin for rotatably connecting the bearing seat 2 and the receiving frame 11; so that the bearing seat 2 can rotate relative to the receiving frame 11.

[0022] The unloading drive transmission unit includes: a fixed bracket 14 connected to the bearing housing 2; a motor 7 mounted on the fixed bracket 14; a first gear 8 mounted on the output shaft of the motor 7; a second gear 6 mounted on the fixed bracket 14 and meshing with the first gear 8; a third gear 12 mounted on the fixed bracket 14 and meshing with the second gear 6; and the third gear 12 meshing with a fourth gear 9 on the shaft 13. This allows the motor 7 to be started to drive the shaft 13 and release the differential ring 5.

[0023] The unloading drive transmission unit can follow the slip ring shaft to rotate during unloading. After reaching the appropriate position, it drives the shaft 13 to rotate and release the slip ring 5, which facilitates unloading and installation of the material cylinder.

[0024] Preferably, the second gear 6 is mounted on a connecting shaft 4 that is axially movable and driven by the cylinder 3, so as to mesh or disengage with the first gear 8. This controls the opening and closing of the transmission chain and prevents misoperation.

[0025] Preferably, the device further includes a winding drive transmission unit disposed on the fixed plate 1. The winding drive transmission unit is used to mesh with the fourth gear 9 on the shaft 13 during winding. In this way, the winding is driven by the winding drive transmission unit during winding, and during unloading, the rotation of the slip shaft disengages the winding drive transmission unit, thus completing the switch between unloading and winding. It should be understood that the specific structure of the winding drive transmission unit is a known structure, and will not be described in detail here.

[0026] Preferably, it also includes a retainer 10 provided at the other end of the shaft 13 for clamping and releasing the shaft 13.

[0027] The clamping and releasing of the shaft 3 are controlled by closing and opening the clamping seat 10. The specific structure of the clamping seat 3 is described in the application filed on the same day.

[0028] The working process of this utility model is as follows: During unloading, the clamp 10 is opened to release the other end of the shaft 13. The differential shaft is rotated, and the shaft seat 2 rotates relative to the receiving frame 11. After reaching the appropriate position, the cylinder 3 is started to push the second gear 6 into the transmission chain. Then, the motor 7 is started to drive the shaft 13 to rotate in the direction of disengaging from the differential ring 5, thereby releasing the differential ring 5 for easy unloading. At the same time, a new material cylinder is installed. The motor 7 is turned off, and the cylinder 3 is controlled to disengage the second gear 6 from the transmission chain. The differential shaft is rotated and clamped by the clamp 10, and the winding drive transmission unit drives the next round of winding.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
