[0030] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 、 Figure 2The utility model provides an embodiment: a labeling machine with automatic width adjustment, including a base 1, which plays a supporting and stabilizing role. A plurality of supporting legs are provided at the bottom of the base 1 to improve the overall stability of the equipment when working. A label roller 2 that cooperates with a pressure roller 4 is rotatably installed on the inner wall of the base 1, and a fixing frame 3 is fixedly connected to the top of the base 1. A pressing mechanism is provided inside the fixing frame 3. A mounting plate 10 for supporting and stabilizing is fixedly connected to the top of the base 1, and a cutting mechanism is provided inside the mounting plate 10. A mounting plate 2 15 is provided on the top of the base 1, and a winding mechanism is provided inside the mounting plate 2 15. The top of the base 1 is fixedly connected to a fixing shell 18 arranged in a horizontal state.

[0032] Reference Figure 2 、 Figure 4 A stretching mechanism is provided inside the fixed shell 18, and the stretching mechanism includes a threaded rod 21, a fixed rod 23 and a slide 25. The threaded rod 21 passes through and is threadedly installed on the inner wall of the fixed shell 18. The right side of the threaded rod 21 is rotatably connected to a moving block 20. The rotation of the threaded rod 21 drives the moving block 20 to move left and right through the action of the thread conversion. The moving block 20 is slidably installed on the inner wall of the fixed shell 18. The sliding direction of the moving block 20 is left and right sliding. The right side of the moving block 20 is hinged with a connecting rod 21 arranged in an inclined state. The number of connecting rods 21 is set to two groups, and the two groups of connecting rods 21 are V-shaped. The end of the connecting rod 21 away from the moving block 20 is hinged with a sleeve block 22, and the top of the base 1 is fixedly connected to a receiving tray 26 for transferring labels.

[0033] Reference Figure 4 The sleeve block 22 passes through and is slidably installed on the outer wall of the fixed rod 23. The sliding direction of the sleeve block 22 is forward and backward. The fixed rod 23 is fixedly installed on the inner wall of the slide 25. The top of the slide 25 and the bottom of the mounting plate 15 are fixedly connected. The number of sleeve blocks 22 is set to two groups. The two groups of sleeve blocks 22 are elastically connected by a spring 24 on the side close to each other. The spring 24 is initially set to a naturally relaxed state without force. The spring 24 is sleeved on the outer surface of the fixed rod 23.

[0034] Reference Figure 1 - Figure 3The pressing mechanism includes a pressing roller 4 and a slider 5. The rotation direction of the pressing roller 4 is opposite to that of the label roller 2. A slide groove 6 that matches the slider 5 is opened on the inner wall of the fixed frame 3. The slider 5 is slidably installed on the inner wall of the slide groove 6. The sliding direction of the slider 5 is up and down. The number of sliders 5 is set to two groups. The front and rear sides of the pressing roller 4 are rotatably installed on the side where the two groups of sliders 5 are close to each other. The label and the base paper are pressed against the top of the surface of the label roller 2 by the downward pressure of the pressing roller 4, thereby improving the friction between the label and the base paper and the surface of the label roller 2, thereby improving the stability of the label and the base paper during transportation, and preventing the label and the base paper from slipping due to insufficient friction.

[0035] Reference Figure 3 The clamping mechanism also includes a spring 7, which is fixedly mounted on the top of the slider 5. The top of the spring 7 is fixedly connected to a pressure block 8, which is slidably mounted on the inner wall of the slide groove 6. The spring 7 applies a downward elastic force to the slider 5. The clamping mechanism also includes a threaded rod 9 arranged in a vertical state. The threaded rod 9 passes through and is threadedly mounted on the inner wall of the fixed frame 3. The bottom of the threaded rod 9 contacts the top of the pressure block 8. When the threaded rod 9 rotates, it will also move up and down linearly under the action of the thread, thereby driving the pressure block 8 to move up and down linearly.

[0036] Reference Figure 2 、 Figure 3 The cutting mechanism includes a knob 11, and the circumferential surface of the knob 11 is provided with an anti-slip key pattern for increasing the friction between the palm and the knob 11, reducing the possibility of slipping and facilitating use. A bidirectional screw rod 12 is fixedly connected to the rear side of the knob 11, and the surface of the bidirectional screw rod 12 is provided with two sections of threads with opposite rotation directions. The bidirectional screw rod 12 passes through and is rotatably mounted on the inner wall of the mounting plate 10, and a tool 13 is slidably connected to the circumferential surface of the bidirectional screw rod 12. The number of tools 13 is set to two groups, and the two groups of tools 13 slide on threads with different rotation directions respectively. When the bidirectional screw rod 12 rotates, the two groups of tools 13 move away from or approach each other, which is convenient for cutting the width of the label and the base paper as needed, and the distance between the two groups of tools 13 is adjusted accordingly. A guide rod 14 is fixedly connected to the surface of the mounting plate 10, and the tool 13 slides on the outer wall of the guide rod 14. The guide rod 14 is used to guide the displacement of the tool 13, so that the tool 13 performs more precise linear motion during displacement, thereby improving the accuracy of displacement and thus improving the quality of cutting.

[0037] Reference Figure 2 、 Figure 4The winding mechanism includes a stepper motor 16, which is fixedly mounted on the front side of the second mounting plate 15. The stepper motor 16 can accurately control the rotation angle of its output shaft, which is convenient for adjusting the winding speed and can be adjusted according to different production requirements. It has good adaptability. The rear end of the output shaft of the stepper motor 16 is fixedly connected to a winding roller 17 for winding the base paper after removing the label, so that the equipment can work continuously and improve work efficiency. The rear end of the winding roller 17 is rotatably mounted on the surface of the second mounting plate 15.

[0038] Working principle: When in use, the label and the backing paper are fed from the right side between the label roller 2 and the pressure roller 4, and then the label and the backing paper are passed under the cutter 13 and fixed on the surface of the winding roller 17, and then the threaded rod 2 19 is rotated. The rotation of the threaded rod 2 19 drives the moving block 20 to move to the left. The displacement of the moving block 20 is caused by the action of the connecting rod 21 to make the two sets of blocks 22 approach each other. The two sets of blocks 22 approach each other and squeeze the spring 2 24, so that the length of the spring 24 is compressed, thereby increasing the elastic force applied by the spring 24 to the two sets of blocks 22, and then making the slide 25 have a tendency to approach the moving block 20, so that the winding roller 17 above the slide 25 maintains a tension on the label and the backing paper when the rod is rotated, reducing the possibility of wrinkles when the label and the backing paper are transported.

[0039] By turning the knob 11, the bidirectional screw rod 12 rotates, and the rotation of the bidirectional screw rod 12 drives the two sets of cutters 13 to move closer to or away from each other. After adjusting the distance between the two sets of cutters 13 according to the width of the label and the bottom paper to be trimmed, the stepper motor 16 is started again. The stepper motor 16 drives the winding roller 17 to rotate, thereby winding the label and the bottom paper. When the label and the bottom paper pass over the receiving tray 26 during the movement, the label will fall off the bottom paper, which is convenient for subsequent labeling of the product.

[0040] On the basis of the above work, by rotating the threaded rod 9, the threaded rod 9 rotates to drive the pressure block 8 to move downward, and the pressure block 8 moves downward and squeezes the spring 7, so that the length of the spring 7 is compressed, thereby increasing the downward pressure of the spring 7 on the slider 5 and the pressure roller 4, so that the pressure roller 4 maintains a certain pressure on the label and the base paper, thereby ensuring that the label and the base paper will neither slip nor be torn due to excessive pulling force during the transportation process, thereby improving the control accuracy and product quality.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
