Description

A book wrapping machine safety pushing device

technical field

The invention belongs to the technical field of printing machinery and relates to a book pushing device for a book wrapping machine.

Background technique

At present, there are relatively few models of book wrapping machines produced at home and abroad, and many book printing factories still pack them manually, which greatly limits work efficiency. Previously produced book wrapping machines had a smaller format and a relatively low speed (0 to 8 books). In addition, the seal sticking mechanism, drying mechanism, and transmission mechanism made the whole machine more restricted. Therefore, many manufacturers prefer to wrap books by hand. As an important part of the book wrapping machine, the book pushing mechanism is an important link in the performance improvement of the book wrapping machine. Reasonable design of the book pushing mechanism plays a vital role in improving the packing efficiency and work safety of the book wrapping machine, as well as reducing energy consumption.

Chinese patent (application number: CN201620295585.9, title of invention: a book wrapping machine based on gear transmission, publication number: CN205631782U, publication date: 2016.04.07) discloses a book wrapping machine based on gear transmission. It includes a housing, a gear transmission mechanism, a paper release shaft, a paper collection shaft, a roller shaft and a separation shaft, and is provided with tension rods and rollers. When working, the self-adhesive book cover is pulled out from the paper release shaft, tensioned by the tension rod, and then the self-adhesive book cover is separated into pad paper after passing through the separation shaft. In the above, after the pad paper is separated, the cover paper is rolled and pasted on the book smoothly by the roller on the roller, and the paper receiving shaft and the paper releasing shaft are driven by a pair of meshing gears, because the speed ratio between the paper releasing shaft and the paper receiving shaft is not constant value, for which the gear ratio adaptive adjustment mechanism is set. However, there are still shortcomings: the working efficiency of the book wrapping mechanism is relatively low and there is no overload protection mechanism. When the mechanism is overloaded (the book output channel is blocked or the book push plate cannot pass because the book pressure plate is too low), the machine is prone to damage. . In response to this problem, in order to further improve the working efficiency and safety of the book wrapping machine, it is necessary to design a forward book pushing mechanism that can realize displacement amplification and overload protection.

detailed description

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

A book pushing device for a book wrapping machine according to the present invention has a structure as shown in Figure 1, including a book pushing platform 1, a book pushing plate 2 is arranged on the book pushing platform 1, and an upper rack 3 is connected to the bottom of the book pushing plate 2, A gear 4 is provided below the upper rack 3, the upper side of the gear 4 meshes with the upper rack 3, the lower side of the gear 4 meshes with the lower rack 5, and the lower rack 5 is connected with the book pushing platform 1 through a support plate 6. The center of the gear 4 is connected to one end of the connecting rod 7, and the other end of the connecting rod 7 is connected to one end of the swing rod 8 (the connecting rod 7 and the swing rod 8 are not on the same straight line). On the groove, the other end of the swing rod 8 is connected with the frame support 10, and the other end of the connecting rod 7 is connected with an overload protection mechanism 11.

Wherein, a notch is provided on the book pushing platform 1, and the upper rack 3 is connected to the bottom of the book pushing plate 2 by bolts, and the upper rack 3 extends from the notch to the book pushing platform 1 and engages with the gear 4.

As shown in Figures 2 and 3, the overload protection mechanism 11 includes a T-shaped compression spring block 11-1, and a through hole A is opened along the central axis of the horizontal block body of the compression spring block 11-1. A through hole B is opened on the central axis of the vertical block of 1, and the through hole A communicates with the through hole B. The other end of the connecting rod 7 is inserted in the through hole A, and a pressure spring is coaxially arranged in the through hole B. 11-2, a spherical pin 11-3 is coaxially sleeved in the stage clip 11-2, and a catch 11-8 is arranged between the pin head of the spherical pin 11-3 and the upper end of the stage clip 11-2, and the spherical pin 11 The lower end of -3 is sleeved in the hollow locking block 11-4, and the spherical pin 11-3 is threadedly connected with the locking block 11-4, and the upper end surface of the locking block 11-4 is pressed against the compression spring 11-2 The lower end of the steel sheet 11-6 is connected on the lower end face of the spherical pin 11-3 by a screw 11-5, and the one side of the steel sheet 11-6 is provided with a microswitch 11-7 (microswitch 11-7 is arranged on the support block 12, and the upper end of the support block 12 is in contact with the lower end surface of the stage clip 11-1 horizontal block body).
