Names corresponding to the marks in the figure:

1. the cutter head comprises a cutter head 10, a mounting part 2, a abdicating disc 3, a cutter head 30, a cutter blade 31, an abdicating step 4, a reinforcing disc 40, a clamping groove 5 and a screw.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art all belong to the protection scope of the present invention.

The embodiment of the utility model provides a:

as shown in fig. 1, the multi-cutter head slotter device of the adhesive binding machine comprises a cutter head 1.

The cutter head 1 is disc-shaped and is rotatably arranged on a rotating shaft in the adhesive binding machine, a connecting hole matched with the rotating shaft is formed in the lower end face of the cutter head 1, and a key groove is formed in the connecting hole; under the action of the rotating shaft, the cutter head 1 can rotate freely.

The circumferential surface of the cutter head 1 is provided with mounting parts 10, the mounting parts 10 are milled mounting planes, and in the embodiment, eight mounting parts 10 are uniformly arranged on the circumferential surface of the cutter head 1 at intervals; each mounting portion 10 is provided with a threaded hole in the radial direction. The mounting parts 10 which are positioned right in the front, right in the back, right in the left and right directions are provided with a cutter head 3 through screws 5; the cutter head 3 is disc-shaped, a round hole penetrates through the middle of the cutter head 3, and the screw 5 penetrates through the round hole and is screwed in a threaded hole in the mounting part 10, so that the cutter head 3 is fixed on the cutter head 1.

Twelve blades 30 are circumferentially arranged on the cutter head 3, and the number of the blades 30 is related to actual requirements, and in other embodiments, other numbers can be set. Blade 30 is the V type form, and the position of keeping away from tool bit 3 center is sharp relatively, can guarantee the back of a book and set up the degree of depth and the regularity of cell body, and the phenomenon that produces the hourglass glue and open the page or leaf takes place when avoiding follow-up glue to order, and blade 30 and tool bit 3 integrated into one piece in this embodiment.

The cutter head 3 in the adhesive binding machine rotates under the rotation of the cutter head 1, and in the rotating process, the blades 30 on each cutter head 1 sequentially pass through the slots in the slotted backer and slot the book backs fixed on the slotted backer; the width of a slot on the slotted backer is matched with that of the blade 30, in order to prevent the cutter head 1 for fixing the cutter head 3 from interfering with the slotted backer, a yielding disc 2 is particularly arranged, the yielding disc 2 is sleeved on the screw 5 and is positioned between the mounting part 10 and the cutter head 3, specifically, one end face of the yielding disc 2 is contacted with the mounting part 10, and the other end face of the yielding disc is contacted with one end face of the cutter head 3; let the diameter of position dish 2 be less than the diameter of tool bit 3 to be less than the thickness of blade disc 1 simultaneously, under the effect of the dish of stepping down 2, can effectively avoid the interference of blade disc 1 and fluting backer.

A reinforcing disc 4 is also provided on the screw 5. Because the head of the screw 5 is smaller than the end surface of the whole cutter head 3, in order to ensure that the screw 5 can well fix the cutter head 3 to prevent the cutter head 3 from rotating in the fixing process, a fixed disc is sleeved on the screw 5, one end surface of the fixed disc is mutually contacted with one end surface of the cutter head 3, the other end surface of the fixed disc is mutually contacted with the head of the screw 5, the fixed disc is mutually contacted with the cutter head 3 by the fastened screw 5, and the probability that the cutter head 3 rotates due to the relative acting force generated by the blade 30 in the grooving process is reduced; the interval is equipped with three joint groove 40 that is used for splines in the circumference edge of reinforcing dish 4, when moving screw 5 twisting, in order to avoid the rotation of tool bit 3 and reinforcing dish 4 to lead to blade 30 position to take place the skew, when screwing up screw 5, can adopt joint spanner and the mutual joint of joint groove 40 on the reinforcing dish 4 simultaneously, thereby guarantee that reinforcing dish 4 takes place to rotate, because reinforcing dish 4 and tool bit 3 contact each other, also can avoid the rotation of tool bit 3 to a certain extent simultaneously.

The cutter head 3 is provided with an annular abdicating step 31, the radial dimension of the abdicating step 31 is smaller than that of the position of the blade 30 on the cutter head 3, and the abdicating step 31 also has the function of avoiding the matching of the cutter head 3 and the slotting backer. In the present embodiment, the cutting head 3 is integrally formed with the relief step 31.

The working principle is as follows:

the let position dish 2, tool bit 3 and reinforcement dish 4 are fixed to be set up on installation department 10 in proper order through screw 5, after fixed, drive the cutter head 1 through the motor and rotate, and four groups of tool bits 3 that are located on the periphery of cutter head 1 will rotate under the rotation of cutter head 1 and cross the slot on the fluting back of a book, and the blade 30 on the tool bit 3 will be drawn across the back of a book to set up the notch on the back of a book, be used for subsequent mucilage binding process. After long-time work, when certain blade on tool bit 3 produced certain wearing and tearing, the shutdown equipment, unscrew screw 5, rotate tool bit 3, make the blade that has worn and torn on the tool bit 3 rotate and leave original position, and make in step not the blade that wears and tear rotate to this position on, set screw 5 again, the change of blade is realized to the interface, whole process is very simple, need not to pull down whole tool bit 3, the time of tool changing has been saved, and tool bit 3 of design can carry out repetitious usage under this kind of mode, and the cost is saved.
