Description

Technical Field

[0001] The utility model relates to the technical field of book binding, in particular to a cover secondary positioning and deviation correction mechanism and a glue binding machine. Background Art

[0002] A perfect binder is a device used to bind printed documents, papers or other materials into a book by gluing them together with a cover.

[0003] At present, cover paper feeding generally adopts vacuum adsorption, using a paper suction component to adsorb the cover to the clamping table to realize automatic cover feeding. For example, Chinese patent CN113400832A discloses an automatic cover feeding mechanism for a glue binder. Through the cooperation of a lifting structure, a creasing structure and a conveying structure, the operator only needs to put multiple covers on the lifting structure at one time, and the conveying structure can automatically move a single cover to the correct position. Its paper suction component includes a suction cup, a suction cup connecting rod and an air guide tube.

[0004] However, when the cover is fed in automatically, when the paper suction component absorbs the top cover paper, it may cause the cover paper below it to move, causing part of the cover paper to be skewed when being absorbed onto the clamping platform, resulting in reduced binding quality.

[0005] Therefore, it is urgent to develop a cover secondary positioning and correction mechanism and a glue binding machine to solve the problems in the existing technology. Utility Model Content

[0006] The utility model aims to provide a cover secondary positioning and correction mechanism and a glue binder, which solves the problem of the poor binding quality caused by the crooked placement of cover paper in the above background technology by setting a first positioning unit with elasticity.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A cover secondary positioning and correction mechanism includes a platform, the upper surface of which is provided with a first positioning unit, at least two of which are provided, and the first positioning unit includes a fixed block, an elastic element and a positioning element; the fixed block is arranged on the platform; one end of the elastic element is connected to the positioning element, and the other end is connected to the fixed block.

[0009] Furthermore, the elastic element includes a spring, the positioning element includes a positioning bar, a cavity is provided in the fixing block, and the spring and the positioning bar are arranged in the cavity.

[0010] Furthermore, the fixing block and the positioning bar are also provided with matching limiting structures for limiting the movement range of the positioning bar in the front-rear direction.

[0011] Furthermore, the positioning element further comprises a positioning stopper, and the positioning stopper is arranged at the front end of the positioning strip.

[0012] Furthermore, the positioning block is slidably connected to the platform.

[0013] Furthermore, the first positioning unit also includes a positioning plate, the upper end of the positioning plate is used to be connected to the suction cup connecting rod of the cover feeding mechanism, and the lower end of the positioning plate cooperates with the positioning stopper.

[0014] Furthermore, a second positioning unit is also provided on the platform, and the second positioning unit includes a positioning block, and the positioning block is slidably connected to the platform.

[0015] Furthermore, a sliding hole is provided on the platform, and a convex block matching with the sliding hole is provided at the lower end of the positioning block, and the convex block penetrates into the sliding hole and has an interference fit with the sliding hole.

[0016] Furthermore, an anti-slip strip is also provided on the positioning block.

[0017] A glue binding machine comprises the cover secondary positioning and deviation correction mechanism.

[0018] Compared with the prior art, the beneficial effect of the utility model is that a first positioning unit including a fixed block, an elastic element and a positioning element is provided, and after the paper suction assembly places the cover, the cover can be rebounded to a predetermined position through the elastic element to avoid the problem of crooked placement of the cover, thereby improving the binding quality.

[0019] At the same time, by setting up the second positioning unit, it can cooperate with the first positioning unit to limit the front end of the cover to further improve the positioning effect.

[0030] In this embodiment, when the cover 4 is inserted, the position where the cover 4 is placed by the cover feeding mechanism is behind the predetermined position, the cover 4 contacts the positioning element, and the elastic elements 22 of the two first positioning units are compressed. When the cover 4 is placed, the elastic element 22 rebounds, and the cover 4 is moved to the predetermined position through the positioning element, so as to avoid the influence of the skewed placement of the cover feeding mechanism on the quality of the binding. Specifically, the predetermined position is the position where the cover 4 should be placed during the binding, and the elasticity of the elastic element 22 can be selected according to the quality of the cover 4.

[0031] In this embodiment, the fixed block 21 is a hollow cuboid provided with a cavity, wherein the opening of the cavity is provided at the front end of the fixed block 21; the elastic element 22 is a spring; and the positioning element includes a positioning bar 231. The spring and the positioning bar 231 are provided in the cavity of the fixed block 21, one end of the spring is connected to the rear end of the positioning bar 231, and the other end is connected to the rear end of the fixed block 21, the positioning bar 231 cooperates with the fixed block 21, the inner wall of the fixed block 21 limits the radial movement of the positioning bar 231, and the positioning bar 231 is slidably connected to the fixed block 21.

[0032] Preferably, the fixing block 21 and the positioning bar 231 are also provided with matching limiting structures to limit the movement range of the positioning bar 231 in the front-rear direction.

[0033] Specifically, a first limiting hole is provided on the positioning strip 231, and two second limiting holes cooperating with the first limiting hole are provided on the fixing block 21. A limiting strip 233 cooperating with the first limiting hole passes through the first limiting hole, and both ends of the limiting strip 233 respectively cooperate with the two second limiting holes and are respectively inserted into the two second limiting holes, and are slidably connected with the fixing block 21 to limit the distance that the positioning strip 231 is pushed out by the spring, thereby improving the positioning accuracy.

[0034] In this embodiment, the positioning element further includes a positioning stopper 232 . The positioning stopper 232 is disposed at the front end of the positioning bar 231 and is fixedly connected to the positioning bar 231 .

[0035] Preferably, the positioning block 232 is slidably connected to the platform 1. Specifically, in this embodiment, a slide groove is provided on the platform 1 to cooperate with the lower end of the positioning block 232, and the positioning block 232 is inserted into the slide groove.

The second positioning unit cooperates with the first positioning unit to limit the cover 4 paper to a predetermined position. The second positioning unit includes a positioning block 31, which is provided on the platform 1 at a side away from the first positioning unit.

[0037] Preferably, the positioning block 31 is slidably connected to the platform 1.

[0040] Embodiment 2

[0041] like Figure 4 As shown, the difference between this embodiment and embodiment one is that the first positioning unit also includes a positioning plate 234, the upper end of the positioning plate 234 is used to connect with the suction cup connecting rod 5 of the cover feeding mechanism, and the lower end of the positioning plate 234 cooperates with the positioning stop block 232.

[0046] When the cover advancing mechanism is separated from the cover 4 and moves away from the first positioning unit, the spring rebounds and moves the cover 4 forward through the positioning element. The second positioning unit limits the excessive forward movement of the cover 4 through the positioning block 31, so that the cover 4 is positioned at a predetermined position.

[0047] Optionally, the cover feeding mechanism may place the cover 4 at a predetermined position, and then move the cover 4 to the predetermined position through a first positioning unit to further prevent the cover 4 from being skewed.
