DETAILED DESCRIPTION

[0067] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0068] In the embodiment of the present invention, please refer to Figures 1 to 10 , a positioning and cutting mechanism of a labeling machine, comprising a housing 1, and also comprising:

[0069] A bottom plate 2 connected to the inner wall of the shell 1;

[0070] A pressure roller 3 is rotatably connected to the bottom plate 2;

[0071] The conveying mechanism 4 is connected to the housing 1 at one end and to the bottom plate 2 at the other end, and is used to convey the label paper. The conveying mechanism 4 includes: a positioning component 41, connected to the housing 1 at one end and to the bottom plate 2 at the other end, and is used to position the label paper; a pushing component 42, connected to the housing 1 at one end and to the positioning component 41 at the other end, and is used to push the positioning component 41 to move; a limiting component 43, connected to the bottom plate 2 at one end and to the positioning component 41 at the other end, and is used to limit the movement of the positioning component 41;

[0072] The cutting mechanism 5 has one end connected to the positioning assembly 41 and the other end connected to the pushing assembly 42, and is used to cut the label paper.

[0073] The label paper is placed on the base plate 2, and the label paper is located between the pressure roller 3 and the base plate 2. The pressure roller 3 flattens the label paper. At the same time, the pressure roller 3 can only rotate in one direction. The positioning component 41 moves downward to squeeze and position the label paper. The pushing component 42 moves to push the positioning component 41 to move horizontally. The positioning component 41 drives the label paper and the cutting mechanism 5 to move a distance of the label paper width. The pushing component 42 continues to move to squeeze the cutting mechanism 5, so that the cutting mechanism 5 moves downward to cut the label paper. After the cutting is completed, the pushing component 42 moves in the opposite direction, so that the cutting mechanism 5 returns to the original position, and the positioning component 41 moves in the opposite direction. At the same time, the limiting component 43 ensures that the positioning component 41 moves upward to separate from the label paper, and then moves in the opposite direction horizontally to return to the original position for the next cutting action.

[0074] As an embodiment of the present invention, please refer to Figures 1 to 5 , the positioning component 41 includes:

[0075] A telescopic member 411, the top end of which is connected to the housing 1;

[0076] A buffer component 412, one end of which is connected to the bottom end of the telescopic member 1 411;

[0077] A slide groove 413 is slidably connected to the other end of the buffer assembly 412;

[0078] A pressing block 414 is connected to a slide slot 1 413;

[0079] A telescopic folding rod 415, the top end of which is connected to the side wall of the pressing block 414;

[0080] A stop plate 416 is connected to the bottom end of the telescopic folding rod 415, and the stop plate 416 is equal in width to the bottom of the pressing block 414;

[0081] An elastic member 417, one end of which is connected to the slide slot 413, and the other end of which is connected to the buffer assembly 412;

[0082] The buffer assembly 412 includes:

[0083] A connecting plate 4121 is connected to the bottom end of the telescopic member 1 411;

[0084] The top end of the telescopic rod 4122 is connected to the connecting plate 4121;

[0085] The slider 4123 is connected to the bottom end of the telescopic rod 4122 and is slidably connected to the slide groove 1 413;

[0086] The second elastic member 4124 is sleeved on the telescopic rod 4122 , and one end of the elastic member 4124 is connected to the connecting plate 4121 , and the other end of the elastic member 4124 is connected to the sliding block 4123 .

[0087] The telescopic member 1 411 drives the connecting plate 4121 to move downward, and then drives the pressing block 414 to move downward, so that the pressing block 414 cooperates with the abutment plate 416 to position the label paper, and the positioning line is the cutting line. The setting of the elastic member 2 4124 buffers the pressure of the pressing block 414, and while ensuring the pressing of the label paper, it can also ensure that the pressing block 414 can drive the slide 1 413 to move horizontally. The setting of the elastic member 1 417 ensures that the pressing block 414 can return to the original position. The telescopic member 1 411 can be a cylinder, an electric telescopic rod, etc., and the elastic member 1 417 and the elastic member 2 4124 can both be springs, springs, etc.

[0088] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 , the pushing assembly 42 comprises:

[0089] The second telescopic member 421, the top end of which is connected to the housing 1;

[0090] The vertical plate 422 is connected to the bottom end of the second telescopic member 421;

[0091] A pressure rod 423, one end of which is rotatably connected to the bottom of the vertical plate 422;

[0092] The equal width component 424 has one end rotatably connected to the other end of the pressure rod 423 and the other end connected to the vertical plate 422;

[0093] The pressing plate 425 is connected to the vertical plate 422;

[0094] The connecting rod 426 is connected to the side wall of the pressing block 414 .

[0095] The equal width component 424 adjusts the inclination of the pressure rod 423 to ensure that the horizontal length of the pressure rod 423 is equal to the width of the label paper. The telescopic component 2 421 drives the vertical plate 422 to move downward, and the vertical plate 422 drives the pressure rod 423 to move downward, so that the pressure rod 423 abuts against the connecting rod 426. The pressure rod 423 squeezes the connecting rod 426, so that the connecting rod 426 drives the pressing block 414 to move. Under the cooperation of the telescopic folding rod 1 415, the pressing block 414 drives the abutting plate 416 and the label paper to move synchronously, and the vertical plate 422 continues to move downward. When the connecting rod 426 abuts against the equal width component 424, the pressing block 414 cannot continue to move. At this time, the pressing block 414 drives the label paper to move a distance of the width of the label paper. The telescopic component 2 421 can be a cylinder, an electric telescopic rod, etc.

[0096] As an embodiment of the present invention, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 , the equal width component 424 includes:

[0097] The bottom end of the connecting tube 4241 is rotatably connected to the other end of the pressing rod 423;

[0098] The sliding rod 4242 is slidably connected to the connecting tube 4241;

[0099] The second slide groove 4243 is connected to the vertical plate 422 and is slidably connected to the top of the sliding rod 4242;

[0100] A threaded rod 4244 connected to the sliding rod 4242;

[0101] The threaded sleeve 4245 is threadedly connected to the threaded rod 4244 and abuts against the second slide groove 4243.

[0102] When it is necessary to adjust the inclination of the pressure rod 423 according to the width of the label paper, rotate the threaded sleeve 4245 so that the threaded sleeve 4245 disengages from the second slide groove 4243, and move the connecting tube 4241 and the sliding rod 4242 laterally according to the width of the label paper. At the same time, the connecting tube 4241 slides on the sliding rod 4242 to adjust the inclination of the pressure rod 423. After the adjustment is completed, rotate the threaded sleeve 4245 in the opposite direction so that the threaded sleeve 4245 abuts against the second slide groove 4243 again, thereby fixing the pressure rod 423, the connecting tube 4241 and the sliding rod 4242.

[0103] As an embodiment of the present invention, please refer to Figures 2 to 5 , Figure 8 and Fig. 9 , the limiting component 43 includes:

[0104] The sliding cavity 431 is provided inside the bottom plate 2;

[0105] The piston rod 432 is connected to the abutment plate 416 and is disposed in the sliding cavity 431 and is slidably connected thereto;

[0106] The air inlet pipe 433 is connected to the interior of the sliding chamber 431, and a one-way valve 1 is provided inside the air inlet pipe 433;

[0107] The air outlet pipe 434 is connected to the interior of the sliding cavity 431, and a second one-way valve is provided inside the air outlet pipe 434;

[0108] A plugging assembly 435 connected to the pressing block 414;

[0109] The blocking assembly 435 includes:

[0110] The third chute 4351 is connected to the side wall of the pressing block 414;

[0111] The top of the second telescopic folding rod 4352 is slidably connected with the third slide groove 4351;

[0112] The blocking block 4353 is connected to the bottom end of the second telescopic folding rod 4352;

[0113] The elastic member 3 4354 has one end connected to the telescopic folding rod 2 4352 and the other end connected to the blocking block 4353 .

[0114] During the pressing process of the pressing block 414, the pressing block 414 drives the blocking block 4353 to move downward synchronously, so that the blocking block 4353 is inserted into the air outlet pipe 434 to block the air outlet pipe 434. At this time, the pressing block 414 continues to move downward until it abuts against the label paper. At this time, the elastic member 4354 undergoes elastic deformation. When the pressing rod 423 squeezes the connecting rod 426 to make the pressing block 414 move laterally, the pressing block 414 drives the abutting plate 416 to move laterally, and the abutting plate 416 drives the piston rod 432 to move laterally, thereby drawing the outside air into the sliding cavity 431 through the air inlet pipe 433. After the label paper is cut, the pressing rod 423 moves upward to return to its original position. When the air outlet pipe 434 is blocked by the blocking block 4353, the gas in the sliding cavity 431 cannot flow out, so that the plate 416 and the pressing block 414 cannot move horizontally back to the initial position, and the telescopic member 1 411 drives the pressing block 414 to move upward. When the pressing block 414 is separated from the label paper, the movement of the pressing block 414 drives the blocking block 4353 to move upward, so that the air outlet pipe 434 is connected to the outside world. Under the reaction force of the elastic member 1 417, the pressing block 414 and the plate 416 move horizontally and return to the original position. Due to the setting of the pressing roller 3, when the plate 416 moves horizontally back to the original position, the label paper will not move horizontally with the plate 416. The elastic member 3 4354 can be a spring, a spring sheet, etc.

[0115] As an embodiment of the present invention, please refer to Figures 1 to 4 , Fig.10 , the cutting mechanism 5 comprises:

[0116] A connecting block 51 connected to a side wall of the pressing block 414;

[0117] The cutting knife 52 is slidably connected to the connecting block 51 and abuts against the front end of the pressing block 414;

[0118] A fixing rod 53, the bottom end of which is connected to the cutting knife 52;

[0119] A horizontal plate 54 connected to the top of the fixing rod 53;

[0120] The elastic member 45 has a bottom end connected to the connecting block 51 and a top end connected to the fixing rod 53.

[0121] The pressing rod 423 squeezes the pressing block 414 to move horizontally. When the connecting rod 426 moves to abut against the connecting tube 4241, the pressing block 414 cannot move further. At this time, the vertical plate 422 continues to move downward, driving the pressing plate 425 to move downward and squeeze the horizontal plate 54. The horizontal plate 54 drives the cutting knife 52 to move downward to cut the label paper. The setting of the elastic member 455 ensures that the cutting knife 52 can return to the original position. The elastic member 455 can be a spring, a spring sheet, etc.

[0122] The working principle of the present invention is as follows: the label paper is placed on the bottom plate 2, and the label paper is located between the pressure roller 3 and the bottom plate 2, the cutting line of the frontmost label paper is aligned with the front end of the abutment plate 416, the pressure roller 3 flattens the label paper, and at the same time, the pressure roller 3 can only rotate in one direction, the threaded sleeve 4245 is rotated to make the threaded sleeve 4245 disengage from the second slide groove 4243, and the connecting cylinder 4241 and the sliding rod 4242 are moved laterally according to the width of the label paper. At the same time, the connecting cylinder 4241 slides on the sliding rod 4242, so as to adjust the inclination of the pressure rod 423. After the adjustment is completed, the threaded sleeve 4245 is rotated in the opposite direction so that the threaded sleeve 4245 is abutted against the second slide groove 4243 again, and the pressure rod 423, the connecting cylinder 4241 and the sliding rod 4242 are fixed;

[0123] The telescopic member 1 411 drives the connecting plate 4121 to move downward, and then drives the pressing block 414 to move downward. During the pressing process of the pressing block 414, the pressing block 414 drives the blocking block 4353 to move downward synchronously, so that the blocking block 4353 is inserted into the air outlet pipe 434 to block the air outlet pipe 434. The pressing block 414 continues to move downward until it contacts the label paper to fix the label paper.

[0124] The second telescopic member 421 drives the vertical plate 422 to move downward, and the vertical plate 422 drives the pressure rod 423 to move downward, so that the pressure rod 423 abuts against the connecting rod 426, and the pressure rod 423 squeezes the connecting rod 426, so that the connecting rod 426 drives the pressure block 414 to move, and under the cooperation of the first telescopic folding rod 415, the pressure block 414 drives the abutting plate 416 and the label paper to move synchronously, and the vertical plate 422 continues to move downward. When the connecting rod 426 abuts against the connecting tube 4241, the pressure block 414 cannot continue to move. At this time, the pressure block 414 drives the label paper to move a distance of the width of the label paper;

[0125] When the pressing block 414 drives the plate 416 to move laterally, the plate 416 drives the piston rod 432 to move laterally, and draws the outside air into the sliding chamber 431 through the air inlet pipe 433;

[0126] The vertical plate 422 continues to move downward, driving the pressing plate 425 to move downward and press the horizontal plate 54, and the horizontal plate 54 drives the cutting knife 52 to move downward to cut the label paper;

[0127] After the cutting is completed, the telescopic member 421 moves upward, so that the cutting knife 52 and the pressure rod 423 return to their original positions. At this time, since the blocking block 4353 blocks the air outlet pipe 434, the gas in the sliding cavity 431 cannot flow out, so that the plate 416 and the pressure block 414 cannot move horizontally back to the initial position. The telescopic member 411 drives the pressure block 414 to move upward. When the pressure block 414 is separated from the label paper, the movement of the pressure block 414 drives the blocking block 4353 to move upward, so that the air outlet pipe 434 is connected to the outside world. Under the reaction force of the elastic member 417, the pressure block 414 and the plate 416 move horizontally and return to the original position. Due to the setting of the pressure roller 3, during the process of the plate 416 moving horizontally back to the original position, the label paper will not move horizontally with the plate 416.

[0128] Repeat the above steps to cut the label paper.
