[0002] The background art provided here is for generally introducing the background of this application. The work of the currently named inventors to the extent described in this background art section, and aspects of this description that do not constitute prior art at the time of application, are neither expressly nor implicitly admitted to be prior art conflicting with this application.

[0003] During the process of a carton processing machine processing cardboard, sometimes after the cardboard is transported out from the paper outlet side of the carton processing machine, subsequent processing of the cardboard is still required, such as horizontal cutting. At this time, since there is no device to press the cardboard, the cardboard will warp or be suspended, which will result in low accuracy of subsequent processing or even inability to perform subsequent processing. In the prior art, to ensure sufficient accuracy of subsequent processing, usually a sufficiently large size is left on the cardboard so that the paper pressing device in the equipment can press the paper to ensure processing, but this will also cause a large amount of cardboard waste in subsequent processing, reducing the utilization rate of the cardboard. Therefore, a new device is needed to solve the above problems. Summary of the Utility Model

[0020] The following description is merely exemplary in nature and is not intended to limit the present application, application or use. Furthermore, there is no intention to be limited by any express or implied theory presented in the preceding technical field, background technology and utility model content or the following detailed description. It should be understood that throughout the drawings, corresponding reference numerals identify similar or corresponding parts or features.

[0021] The present application will now be further described. In the following paragraphs, different aspects of the present application are defined in more detail. Unless clearly indicated to the contrary, each aspect so defined may be combined with any other aspect(s). In particular, any feature indicated as being preferred or advantageous may be combined with any other feature(s) indicated as being preferred or advantageous.

[0022] In view of the problems existing in the prior art, the present application provides an auxiliary paper feeding device, which can be installed on the paper output side of a carton processing machine and press and fix the cardboard transported from the paper output side, so as to perform subsequent processing on it and ensure the processing accuracy.

[0023] Refer to the appended Figure 1 and the appended Figure 2 , which shows an auxiliary paper feeding device 100 according to the principle of the present application. The auxiliary paper feeding device 100 includes a support frame 110, a paper pressing mechanism 120, a paper feeding mechanism 130 and a connecting mechanism 140. Among them, the paper pressing mechanism 120 is located at a set distance above the paper feeding mechanism 130, so as to form a gap with a certain height between the two, so that the cardboard can pass through it. The set distance can be determined according to the thickness of the cardboard, so that the cardboard can pass through the gap smoothly. The paper pressing mechanism 120 includes a paper pressing wheel 121, which can rotate around a rotating shaft, and the number of paper pressing wheels 121 can be one, two or more. The paper feeding mechanism 130 includes a paper feeding roller 131, and one end of the paper feeding roller 131 can be connected to a motor to provide power for the rotation of the paper feeding roller 131. Alternatively, in some embodiments, there is no gap between the paper pressing wheel 121 and the paper feeding roller 131, and the rotating shaft of the paper pressing wheel 121 is connected to an elastic device such as a cylinder or a spring. When the cardboard advances, it can force the paper pressing wheel 121 to contract upward, so as to form a gap between the paper pressing wheel 121 and the paper feeding roller 131, so that the cardboard can pass through it.

[0024] When the cardboard comes out from the paper output side of the carton processing machine and enters the gap between the paper pressing mechanism 120 and the paper feeding mechanism 130, the paper feeding roller 131 can rotate to continue driving the cardboard forward by relying on the friction force between it and the cardboard. At this time, the paper pressing wheel 121 can press on the upper side of the cardboard, so that the cardboard can remain stable during the forward movement, so as to perform subsequent processing on it. Both ends of the paper pressing mechanism 120 and the paper feeding mechanism 130 are connected to the connecting mechanism 140, and the connecting mechanism 140 is connected to the support frame 110, so that both ends of the paper pressing mechanism 120 and the paper feeding mechanism 130 can be connected to the support frame 110.

[0025] Refer to the appended Figure 1 and the appended Figure 3, the support frame 110 may include a lifting mechanism 150. The connecting mechanism 140 is connected to the lifting mechanism 150, so that the paper pressing mechanism 120 and the paper feeding mechanism 130 connected to the connecting mechanism 140 can be lifted, so as to adjust the height of the paper pressing mechanism 120 and the paper feeding mechanism 130 from the ground and align them with the paper outlet of the carton processing machine. Preferably, in some embodiments, the lifting mechanism 150 includes a lead screw lift 151. The lead screw lift 151 includes a lead screw 152, a lifting block 153 and a lead screw motor 154. The lifting block 153 is fixedly connected to the connecting mechanism 140, and a worm and gear mechanism (not shown) connected to the lead screw 152 is provided inside the lifting block 153. The output end of the lead screw motor 154 is connected to the worm and gear mechanism, and the lifting block 153 is driven to move along the lead screw 152 by driving the worm and gear mechanism, thereby driving the paper pressing mechanism 120 and the paper feeding mechanism 130 to lift. Optionally, the lead screw motor 154 may be located at one end, both ends or the middle position in the length direction of the paper pressing mechanism 120 or the paper feeding mechanism 130. In some embodiments, the lead screw motor 154 is located at one end of the paper pressing mechanism 120 or the paper feeding mechanism 130, and is connected to the lifting block at the other end through a lead screw motor transmission shaft (not shown) to drive its lifting. It should be understood that the structure of the lead screw lift is simple, easy to operate, and has high precision, which can well meet the lifting requirements.

[0026] Referring to the attached Figure 1 and the attached Figure 3 , advantageously, the lifting mechanism 150 further includes a slide rail 155. The connecting mechanism 140 is provided with a slider 141 that can cooperate with the slide rail 155, and the slider 141 is slidably connected to the slide rail 155. When the connecting mechanism 140 is lifted by the lead screw lift 150, the slider 141 can slide along the slide rail 155, thereby enhancing the stability of the connecting mechanism 140. It is easy for those skilled in the art to understand that according to the size of the connecting mechanism 140, the slide rail 155 can be provided with 1, or 2 or more.

[0027] Alternatively, in some embodiments, the lifting mechanism 150 may include a hydraulic lift (not shown), and the connecting mechanism 140 may be connected to the hydraulic lift to achieve lifting. It should be understood that in this case, the lifting mechanism 150 may also include a slide rail 155, and the connecting mechanism 140 may also be provided with a slider 141 to enhance the stability of the connecting mechanism 140 through their sliding connection. It is easy for those skilled in the art to understand that the lifting mechanism 150 may also include other types of lifts, such as lifts that perform lifting transmission through chain drive, belt drive, crank and connecting rod, etc.

[0028] Referring to the attached Figure 1, the paper pressing mechanism 120 may include a protective housing 122, which is located above the paper pressing wheel 121 to protect the paper pressing wheel 121. Advantageously, the top of the protective housing 122 is flat. Thus, when it is necessary to repair or maintain the carton processing machine, only the paper pressing mechanism 120 and the paper feeding mechanism 130 need to be lowered to an appropriate position without removing the entire auxiliary paper feeding device, and the top of the protective housing 122 can be stepped on by the maintenance personnel to carry out repair or maintenance operations.

[0029] Refer to the attached Figure 1 and the attached Figure 3 , the support frame 110 may be provided with a limit sensor 111 to detect the positions of the paper pressing mechanism 120 and the paper feeding mechanism 130. When the limit sensor 111 detects that the paper pressing mechanism 120 and the paper feeding mechanism 130 are lifted or lowered to the target positions, the lifting or lowering can be stopped. The limit sensor 111 may be at the bottom of the support frame 110. Advantageously, casters 112 may be provided at the bottom of the support frame 110 to facilitate the movement of the entire auxiliary paper feeding device. Advantageously, the support frame 110 may also be provided with a device connection part 113, and the device connection part 113 may be provided with threaded holes, snap structures or other connection devices so that the auxiliary paper feeding device 100 can be connected to the carton processing machine by threads or snaps. In some embodiments, the device connection part 113 may be connected to the support frame 110 by a pin. When it is necessary to separate the auxiliary paper feeding device 100 from the carton processing machine, the pin can be pulled out to achieve quick separation. In some embodiments, the device connection part 113 may be fixedly connected to the support frame 110. When it is necessary to separate the auxiliary paper feeding device 100 from the carton processing machine, separation can be achieved by screwing out bolts, opening snaps, etc.

[0030] Refer to the attached Figure 4 , in some embodiments, the auxiliary paper feeding device 100 can be split into a first body 101 and a second body (not shown) along its length direction. When it is necessary to transport it, the auxiliary paper feeding device can be split into the first body and the second body for packaging to reduce the packaging volume. When it is necessary to use it, the first body and the second body can be connected. It should be understood that in this case, the support frame 110, the paper pressing mechanism 120, the paper feeding mechanism 130, and the lead screw motor transmission shaft can all be split into two parts along their length directions. In some embodiments, the two parts of the paper feeding roller 131 can be detachably connected by a first coupling 132, and the two parts of the lead screw motor transmission shaft can be detachably connected by a second coupling 156.

[0031] In another aspect of the present application, a carton processing machine is also provided. The carton processing machine includes an auxiliary paper feeding device according to the principle of the present application and has the advantages as described above.

[0032] The auxiliary paper feeding device and the carton processing machine according to the present application can press the cardboard when it comes out from the paper outlet side of the carton processing machine, so as to perform subsequent processing on the cardboard. The auxiliary paper feeding device has a simple structure and can adjust its height according to the height of the paper outlet of the carton processing machine, so that it can adapt to carton processing machines of different sizes and specifications. In addition, the auxiliary paper feeding device can also be disassembled for easy transportation. In summary, the auxiliary paper feeding device and the carton processing machine according to the principle of the present application effectively solve the problems existing in the prior art.
