Detailed Implementation

[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0022] Example:

[0023] like Figures 1-5 As shown, a printing paper feeding device includes a support frame 1, a conveyor 2 installed at the top of the support frame 1, a drive mechanism 3 at the end of the conveyor 2, a conveyor belt 4 connected to the drive mechanism 3, a first protective mechanism 5 movably connected to the outer wall of the conveyor 2, a second protective mechanism 6 at the upper end of the drive mechanism 3, and two sets of the first protective mechanisms 5, which cover the conveyor belt 4 for protection by sliding and closing.

[0024] The first protective mechanism 5 includes a first protective plate 51 set at the upper end of the conveyor 2, a slider 52 fixed on the outer wall of the bottom end of the first protective plate 51, a groove 53 opened in the inner wall of the conveyor 2, a movable groove 54 opened in the first protective plate 51, a threaded groove 55 opened in the conveyor 2, a threaded rod 56 inserted into the movable groove 54 and threadedly connected to the threaded groove 55, and a nut 57 fixed on the outer wall of the top end of the threaded rod 56.

[0025] When the staff does not need to use the conveyor belt 4, only need to move the first guard plate 51 at both ends inward, so that the first guard plate 51 slides in the sliding groove 53 through the sliding block 52, until the two groups of first guard plates 51 are attached to each other, covering the conveyor belt 4 completely, at this time, slide the threaded rod 56, so that the threaded rod 56 moves in the movable slot 54 to coincide with the threaded groove 55, then turn the nut 57 inward, the nut 57 drives the threaded rod 56 to rotate inward and tighten in cooperation with the threaded groove 55.

[0026] It is worth noting that the sliding groove 53 is symmetrically provided with two groups, and the length of each group of sliding grooves 53 is greater than the width of the conveyor belt 4. The purpose of designing the two groups of sliding grooves 53 is to ensure that the first guard plate 51 can slide without being limited by the width of the conveyor belt 4, and can completely cover the conveyor belt. When the conveyor belt 4 is in working condition, the first guard plate 51 slides in the sliding groove 53 through the sliding block 52. Since the length of each group of sliding grooves is greater than the width of the conveyor belt 4, it can be ensured that the guard plate can cover the entire conveyor belt when moving without being unable to cover the entire conveyor belt due to insufficient space;

[0027] The movable slot 54 is symmetrically provided with two groups on the first guard plate 51, and the shape of each group of movable slots 54 is set as a waist round shape. The waist round shape of the movable slot 54 can provide sufficient space for the threaded rod 56 to move smoothly in the movable slot and be precisely connected with the threaded groove 55. The design of the waist round shape may help to improve the stability of the adjustment process, avoid excessive friction, and ensure smooth operation;

[0028] The bottom end of the nut 57 is provided with a soft pad, and the outer wall of the nut 57 is provided with anti-skid lines;

[0029] The second guard mechanism 6 includes two groups of fixed plates 61 symmetrically fixed on the side walls of the conveying table 2, a rotating shaft 62 rotatably connected between the two groups of fixed plates 61, and a second guard plate 63 sleeved on the outer wall of the rotating shaft 62;

[0030] When the first guard mechanism 5 covers the conveyor belt 4 completely, there is still a part of the conveyor belt 4 exposed above the driving mechanism 3. At this time, only need to rotate the second guard plate 63, so that the second guard plate 63 drives the rotating shaft 62 to rotate between the two groups of fixed plates 61, and finally the second guard plate 63 covers and protects the exposed part of the conveyor belt 4.

[0031] In the utility model, unless another definite provision and limitation, first feature is "on" or "under" second feature can include that first and second features are in direct contact, also can include that first and second features are not in direct contact but are in contact through other features between them. Moreover, first feature "on", "above" and "on" second feature include that first feature is directly above and obliquely above second feature, or only indicates that first feature is higher than second feature in horizontal height. First feature "under", "below" and "under" second feature include that first feature is directly below and obliquely below second feature, or only indicates that first feature is lower than second feature in horizontal height.

[0032] The basic principle, main features and advantages of the utility model are shown and described above. The skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments, the above-mentioned embodiments and the description in the specification are only preferred examples of the utility model and are not used to limit the utility model, various changes and improvements of the utility model can be made without departing from the spirit and scope of the utility model, these changes and improvements all fall into the scope of the utility model claimed for protection, the scope of protection of the utility model is defined by the appended claims and equivalents thereof.
