[0040] Refer to the following Figures 1 to 5 The present invention describes a label detection device for a label printing machine and a labeling machine according to an embodiment of the present application.

[0041] See also Figures 2 to 5 As shown, an embodiment of the present application provides a label detection device for a printing and labeling machine. The label detection device for a printing and labeling machine includes: a fixed connection member 2, a detection bracket 1, a supporting member 4, and an image detection device 3, wherein the fixed connection member 2 and the supporting member 4 are spaced apart, and the fixed connection member 2 and the supporting member 4 are respectively fixed to their respective designated positions, thereby fixing the label detection device for the printing and labeling machine. The detection bracket 1 is rotatably connected to the fixed connection member 2, and the detection bracket 1 overlaps the supporting member 4. As the detection bracket 1 rotates, the detection bracket 1 can leave the supporting member 4 or overlap the supporting member 4. The detection bracket 1 is provided with a mounting surface 101 for mounting the image detection device 3. After the image detection device 3 is mounted on the mounting surface 101, the image detection device 3 can be set toward the label to detect the printed content and print quality of the label. The image detection device 3 can specifically be an image sensor commonly used in the art. When the detection bracket 1 is attached to the support member 4, a label dispensing passage is formed below the mounting surface 101. Printed labels pass through the dispensing passage one by one, and during this process, the printed content of the labels is inspected by the image inspection device 3. When the detection bracket 1 is separated from the support member 4 and is in the open position, the image inspection device 3 can be exposed for cleaning. After cleaning, the image inspection device 3 is rotated back to its original position with the detection bracket 1, and subsequent label printing and label content inspection can be carried out.

[0042] Specifically, the label detection device for the printing and labeling machine also includes a support member 8, which is in the shape of a long strip. The support member 8 can be a rod or a plate. One end of the support member 8 is connected to the fixed connecting member 2, and the other end of the support member 8 is connected to the supporting member 4. The support member 8 is located below the mounting surface 101 of the detection bracket 1. The above-mentioned label output channel is formed between the upper surface of the support member 8 and the lower surface of the mounting surface 101. At the same time, the label output channel is also a detection channel for the image detection device 3 to fully identify the label. Preferably, the height of the detection channel is 0.4-1.2 mm, and the accuracy of label detection and identification can be ensured within this range.

[0043] Furthermore, the fixed connection member 2 includes a fixed portion 202, a connection portion 201, and a rotating connection member 203. Preferably, the fixed portion 202 and the connection portion 201 have an integral structure, the connection portion 201 is located below the fixed portion 202, and at least the fixed portion 202 is connected to a designated position between the connection portion 201 and the fixed portion 202. The connection portion 201 is plate-shaped, and the connection portion 201 is provided with a first connecting arm 204 and a second connecting arm 205 on both sides facing each other. The first connecting arm 204 and the second connecting arm 205 are raised relative to the surface of the connection portion 201 facing the detection bracket 1. The rotating connection member 203 can be specifically a pin, one end of the rotating connection member 203 is passed through the first connecting arm 204, and the other end of the rotating connection member 203 is passed through the second connecting arm 205. The connecting portion 201 is further provided with a locking portion 206, which is arranged above the second connecting arm 205. The locking portion 206 and the second connecting arm 205 are distributed in an L shape. The locking portion 206, the second connecting arm 205 and part of the surface of the connecting portion 201 jointly define a locking space.

[0044] Furthermore, the label detection device for the printing and labeling machine further includes a reset member 5 , which is specifically a compression spring. The reset member 5 is sleeved on the rotating connecting member 203 .

[0045] Furthermore, the detection bracket 1 is in the shape of an elongated strip. Preferably, the detection bracket 1 has a rectangular structure. One end of the detection bracket 1 is a hinged end, and the hinged end is provided with a through hole. The rotating connecting member 203 is passed through the through hole to hinge the hinged end to the connecting part 201; the other end of the detection bracket 1 is a lap end, and the lap end is used to lap to the supporting member 4.

[0046] An abutment notch 102 is provided at a top corner of the hinged end near the first connecting arm 204, and a perforation is connected to the abutment notch 102. The distance between the first connecting arm 204 and the second connecting arm 205 is greater than the width of the detection bracket 1, so that the detection bracket 1 can move between the first connecting arm 204 and the second connecting arm 205. One end of the reset member 5 abuts the inner wall surface of the first connecting arm 204, and the other end of the reset member 5 abuts the detection bracket 1 within the abutment notch 102. The state in which the overlapping end overlaps the supporting member 4 is defined as the closed state of the label detection device for the printing and labeling machine, and the state in which the overlapping end leaves the supporting member 4 and the detection bracket 1 approaches the fixed connecting member 2 and moves away from the support member 8 is defined as the open state. When the detection bracket 1 is in the closed state, the reset member 5 is compressed when the detection bracket 1 is pulled so that the detection bracket 1 can move closer to the first connecting arm 204. The detection bracket 1 is removed from the locking space, and the detection bracket 1 and the image detection device 3 can be lifted upward to adjust the detection bracket 1 from the closed state to the open state, and the image detection device 3 can be cleaned, repaired, etc.

[0047] Preferably, the top corner of the first connecting arm 204 is chamfered. Since the detection bracket 1 is provided with an abutment notch 102, when the detection bracket 1 moves out of the locking space and approaches the first connecting arm 204, after the detection bracket 1 is lifted, the abutment notch 102 can avoid each other with the top corner of the first connecting arm 204, thereby increasing the lateral provided distance of the detection bracket 1.

[0048] Furthermore, the supporting member 4 includes a connecting base 402 and a supporting platform 401, the connecting base 402 is used to be fixed to a specified position, and the supporting platform 401 includes a first plate portion and a second plate portion distributed in an L-shape, the connecting base 402 is arranged at the bottom of the first plate portion, and the second plate portion is located on the side of the first plate portion. When the detection bracket 1 is in a closed state, the overlapping end of the detection bracket 1 is overlapped on the supporting platform 401, and the second plate portion is located on the side of the detection bracket 1 close to the second connecting arm 205. The second plate portion can block the detection bracket 1 to prevent the detection bracket 1 from sliding off the supporting platform 401.

[0049] Furthermore, a partial absence at the end of the overlapping end forms an avoidance portion 103, and the shape of the avoidance portion 103 is adapted to the shape of the supporting platform 401, so that the overlapping end is overlapped on the supporting platform 401 in a sinking manner through the avoidance portion 103, thereby ensuring to the greatest extent that the two ends of the detection bracket 1 are at the same height.

[0050] Furthermore, the label detection device for the printing and labeling machine also includes a first stop member 6 and a second stop member 7. A limiting block 207 is provided on the side surface of the fixed portion 202 facing the detection bracket 1. The limiting block 207 has a suction surface 208 on the side surface facing the detection bracket 1. The suction surface 208 is provided with an embedding groove. The first stop member 6 is embedded in the embedding groove, and the surface of the first stop member 6 is kept flush with the suction surface 208. The limiting block 207 can limit the opening angle of the detection bracket 1. The suction surface 208 can be a vertical plane or an inclined surface.

[0051] The second stopper 7 is embedded in the detection bracket 1, and the surface of the second stopper 7 is flush with the upper surface of the detection bracket 1. When the detection bracket 1 is lifted, the second stopper 7 is adapted to connect with the first stopper 6, thereby allowing the detection bracket 1 to stay in the open state. Preferably, the first stopper 6 is a magnet and the second stopper 7 is a suction screw.

[0052] To sum up, the label detection device for a printing and labeling machine provided in the present application places the image detection device 3 on the detection bracket 1. The image detection device 3 can be opened by operating the detection bracket 1 to open the detection bracket 1, so as to clean foreign matter on the surface of the image detection device 3. The operation is simple and convenient. The detection bracket 1 and the image detection device 3 do not interfere with other structures and components of the labeling machine. There is no need to open other components such as the print head, which reduces the tediousness of disassembly and assembly and avoids repeated corrections that cause waste of label paper.

[0053] like Figure 1 As shown, an embodiment of the present application further provides a labeling machine, comprising the label detection device for a printing and labeling machine described in any of the above embodiments, and thus, having all the beneficial technical effects of the label detection device for a printing and labeling machine, which will not be repeated here.

[0054] The labeling machine also includes a shell 9. The label detection device for the printing labeling machine and some other necessary components of the labeling machine are arranged in the installation cavity inside the shell 9. The fixing connector 2 and the supporting member 4 of the label detection device for the printing labeling machine are respectively connected to the designated positions in the shell 9, thereby fixing the label detection device for the printing labeling machine in the shell 9.

[0055] It should be noted that the above-mentioned support member 8 can specifically be a tearing rod of a labeling machine. When the label detection device used for the printing labeling machine is in a closed state, the tearing rod is located below the detection bracket 1. Preferably, the tearing rod is arranged parallel to the mounting surface 101 of the detection bracket 1. As the printing process continues to advance, the label is gradually delivered with the backing paper. The backing paper can be pulled downward to make the backing paper contact with the tearing rod, and the backing paper can be torn along the tearing rod.

[0056] The labeling machine provided in the present application optimizes the setting position of the image detection device 3 through the above-mentioned label detection device for the printing and labeling machine, so that the image detection device 3 can be opened and closed independently without the need to disassemble other components, thereby enabling the image detection device 3 to be conveniently opened for cleaning and maintenance.
