[0057] In addition, it should be noted that in the description of this application, unless otherwise clearly specified and limited, the term "installation" and the like should be understood in a broad sense, for example, it can be a fixed installation or a detachable installation.

[0058] For those skilled in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0059] like Figure 1-Figure 5 The structure of the embodiment of the present application is shown.

[0060] The carton binding machine head provided in this embodiment includes an anti-breakage plate mechanism.

[0061] The anti-breakage plate mechanism includes an anti-breakage horizontal connecting rod 5, an anti-breakage vertical connecting rod 6, an anti-breakage tension spring suspension rod 9, an anti-breakage tension spring 10, and an anti-breakage plate 10.

[0062] The two sides of the anti-breakage plate 10 are respectively connected to the lower end of an anti-breakage tension spring 10, the upper ends of the two anti-breakage tension springs 10 are respectively connected to the lower end of an anti-breakage tension spring suspension rod 9, the upper ends of the anti-breakage tension spring suspension rod 9 are respectively connected to the two ends of the anti-breakage horizontal connecting rod 5, the lower end of the anti-breakage horizontal connecting rod 5 is connected to the upper end of the anti-breakage vertical connecting rod 6, and the lower end of the anti-breakage vertical connecting rod 6 is connected to the upper end of the sliding fork knife 7.

[0063] It should be noted that the anti-breakage horizontal connecting rod 5, the anti-breakage vertical connecting rod 6 and the anti-breakage tension spring hanger 9 in the present application can be block-shaped, columnar or irregular in shape, which is not limited in the present application and all belong to the protection scope of the present application; in addition, the anti-breakage horizontal connecting rod 5, the anti-breakage vertical connecting rod 6 and the anti-breakage tension spring hanger 9 can be straight rod-shaped or bent, which is not limited in the present application and all belong to the protection scope of the present application; the anti-breakage horizontal connecting rod 5, the anti-breakage vertical connecting rod 6 and the anti-breakage tension spring hanger 9 can be an integrated structure or a spliced ​​structure, which is not limited in the present application and all belong to the protection scope of the present application.

[0064] like Figure 6 As shown, it is a schematic diagram of the working process of the anti-breakage plate mechanism in this application.

[0065] The eccentric gear shaft 8 drives the sliding fork knife 7 and places it at the high point H1. H1 is the maximum distance between the lower end of the sliding fork knife 7 and the bottom mold of the suspension beam. At this time, it is the maximum upper limit of the stretching of the anti-breakage tension spring 10. At the same time, the flat wire conveying mechanism has fully fed the raw flat wire. The eccentric gear shaft 8 continues to rotate counterclockwise, and the sliding fork knife 7 is cut and bent downward, and presses against the anti-breakage plate 11. At this time, the anti-breakage tension spring 10 is still in a state of pulling, that is, the anti-breakage tension spring 10 provides tension during the entire working process. When the sliding fork knife 7 works downward, the bottom of the anti-breakage plate 11 first presses the cardboard, and the sliding fork knife 7 is on top, and the cardboard is not damaged. After the binding is completed, the anti-breakage plate 11 is held by power, and the upward speed of the anti-breakage plate can reach the same speed as the design speed of the machine head.

[0066] Because the anti-breakage plate 11 and the sliding fork knife 7 withdraw at the same speed, when the binding is completed, the sliding fork knife 7 moves up and the paper feeding device can transport the paperboard, which greatly improves the binding speed. This process is not available in China or even abroad.

[0067] In a preferred embodiment, Figure 7 , Figure 8 As shown, a preferred transmission mechanism of a carton binding machine head is provided, wherein the transmission mechanism includes an eccentric gear shaft 8, an intermediate gear 13 and a wire feeding wheel 14, wherein the eccentric gear shaft 8 is transmission-connected with the intermediate gear 13, and the intermediate gear 13 is transmission-connected with the wire feeding wheel 14.

[0068] Among them, the vertical center distance between the eccentric gear shaft 8 and the intermediate gear 13 is 25.00mm±2mm, preferably 25.00mm; the horizontal center distance between the eccentric gear shaft 8 and the intermediate gear 13 is 61.89mm±2mm, preferably 61.89mm; the horizontal center distance between the intermediate gear 13 and the wire feeding tooth 14 is 66.75mm±2mm, preferably 61.89;

[0069] In addition, the gear module m of the eccentric gear shaft 8, the intermediate gear 13 and the wire feeding wheel is 1.5.

[0070] Among them, the number of teeth on the tooth portion of the eccentric gear shaft 8 is 38, the number of teeth on the tooth portion of the intermediate gear 13 is 51, and the number of teeth on the tooth portion of the wire feeding wheel is 38.

[0071] The use effect is better by adopting the above structure.

[0072] When a traditional carton binding machine is in use, the flat wire is squeezed and transported by the wire feeding wheel and the wire pressing wheel. The wire feeding length for each binding is fixed, and the wire feeding length must be greater than the normal use length. This length difference is also called excess length. During the transmission of this section of flat wire with excess length, the wire feeding wheel and the wire pressing wheel will cause extrusion and friction on it. The extrusion and friction of the two wheels will definitely have an adverse effect on the flat wire coating, and coating shavings will be generated. The destruction of the flat wire coating affects the binding quality, and the deposition of coating shavings will cause poor wire feeding, machine shutdown, and production impact. In order to solve this problem, such as Figure 9-13 As shown, the present embodiment provides a carton binding machine head, the specific structure of which is as follows:

[0073] Including wire feeding mechanism,

[0074] The wire feeding mechanism includes a curved rail structure, which includes a wire feeding curved rail 103. A wire feeding groove for the flat wire to pass through is provided at one end of the outer side of the wire feeding curved rail 103. The wire feeding curved rail 103 is used in conjunction with a wire pressing plate, and the wire pressing plate covers the outer side of the wire feeding groove so that the flat wire is fed along the wire feeding groove.

[0075] The wire pressing plate includes a fixed wire pressing plate and a rotating wire pressing plate 105, the fixed wire pressing plate is fixedly connected to the wire feeding curved rail 103, and can be fixed with screws, the lower end of the rotating wire pressing plate 105 is hingedly connected to the rotating wire pressing plate seat 106, so that the rotating wire pressing plate 105 can rotate around one hinged end, the rotating wire pressing plate seat 106 is fixedly connected to the wire feeding curved rail 103, and the rotating wire pressing plate 105 can also be directly hingedly connected to the wire feeding curved rail 103;

[0076] The rotating wire pressing plate 105 is connected to the elastic reset component so that after rotating around one end of the hinge, it can be reset by using the force generated by the elastic reset component. Specifically, the structure of the elastic reset component can adopt the following structure, or other structures that can achieve this function:

[0077] The first type, the elastic reset component includes a tension spring 104 and a tension spring connecting column 107, the upper end of the rotating wire pressing plate 105 is connected to one end of a tension spring 104, the other end of the tension spring 104 is connected to the tension spring connecting column 107, and the tension spring connecting column 107 is fixedly connected to the panel 108 or connected to other locations where it can be installed;

[0078] The second type, such as Fig.16As shown, the elastic reset component includes a compression spring rod 1016 and a compression spring 1017, one end of the compression spring 1017 is crimped onto the outer side of the upper end of the rotating wire pressing plate 105, and the other end of the compression spring 1017 is connected to the compression spring rod 1016, wherein the compression spring rod 1016 is fixedly connected to the panel 108 or the wire feeding bending rail 103, or other locations where it can be installed.

[0079] The fixed wire pressing plate includes an upper wire pressing plate 1012 and a lower wire pressing plate 1013 , and the wire feeding curved rail 103 sequentially connects the upper wire pressing plate 1012 , the rotating wire pressing plate 105 and the lower wire pressing plate 1013 from top to bottom.

[0080] The wire feeding mechanism also includes a wire drawing block 101, a wire pressing wheel 102 and a wire feeding wheel 14 installed on a panel 108. The wire pressing wheel 102 and the wire feeding wheel 14 are used in conjunction with each other and are arranged below the wire drawing block 101. The wire feeding curved rail 103 is arranged below the wire pressing wheel 102 and the wire feeding wheel 14.

[0081] The buffer wire feeding process of the present application is described as follows.

[0082] like Fig.14 As shown, when the wire feeding wheel and the wire pressing wheel have fully fed the raw material flat wire, the excess length of the flat wire is subjected to the clamping thrust of the wire pressing wheel and the wire feeding wheel, thereby deforming into an arc shape. The force generated by the arc-shaped flat wire pushes the rotating wire pressing plate to rotate counterclockwise around one hinged end, so that the excess length of the flat wire will no longer be squeezed and rubbed by the wire feeding wheel and the wire pressing wheel. When the wire feeding part of the wire feeding wheel completes wire feeding, it enters a non-wire feeding state. At this time, the rotating wire pressing plate returns to its original position through the tension of the tension spring or the elastic force of the compression spring, and the flat wire moves in the opposite direction for a distance, completing the entire wire feeding process. In this process, there is no squeezing and friction between the wire feeding wheel and the pressing wheel.

[0083] In a preferred embodiment,

[0084] The rotary pressing plate 105 is connected with a sensor baffle 109 , a sensor bracket 1011 is installed on the panel, a sensor 1010 is installed on the sensor bracket 1011 , the sensor 1010 is used in conjunction with the sensor baffle 109 , and the sensor bracket 1011 is installed on the back side of the panel.

[0085] During the box binding process, if the flat wire fails to be transported, the rotating wire pressing plate 105 cannot be pulled back by the tension spring, and the flat wire transport mechanism is still working, the sensor baffle 109 and the sensor 1010 play a role, the sensor 1010 collects signals, outputs signals to alarm, and the control mechanism controls the whole machine to stop automatically after receiving the signals, thereby effectively preventing the flat wire from bending and curling. It is understood that the above-mentioned improved structure has not been disclosed at home and abroad.

[0086] In a preferred embodiment,

[0087] like Fig.15 As shown, the carton binding machine head also includes a sheath, and a mounting hole is respectively provided on the left and right sides of the lower end of the sheath. A lower blade 1014 used in conjunction with a wire feeding mechanism is provided in the left mounting hole, and a top wire block 1015 is provided in the right mounting hole.

[0088] In the present application, the lower blade 1014 and the top screw block 1015 are both embedded in the sheath and fastened with screws. This structure is an integrated design, which has the advantages of compact structure and high connection strength. Among them, the distance between the dimension at A and the lower blade and the top screw block installation hole is short, which can greatly increase the thickness space of the binding cardboard and effectively adjust the space for installing the anti-breakage board.

[0089] In addition, in the present application, a carton binding machine is also provided, which includes the structure of the carton binding machine head mentioned above, and also includes structures such as a cantilever bottom mold bracket 1 and a cantilever bottom mold 2, which will not be described in detail here.

[0090] It should be noted that the technical solutions not described in detail in this application adopt publicly known technologies.

[0091] The above is only a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
