[0037] This embodiment provides a label cutting device, as Figures 1-5 shown. The label cutting device includes a fixed table 1, and a feeding reel assembly 2, a cutting assembly 3, and a winding reel assembly 4 that are sequentially arranged on the fixed table 1. The winding reel assembly 4 includes a driving unit 41 and a reel recovery cylinder 42. The driving unit 41 can drive the reel recovery cylinder 42 to rotate. After the uncut label roll passes through the feeding reel assembly 2, its end is pulled to the cutting assembly 3. After cutting, it is wound around the reel recovery cylinder 42 through the driving unit 41.

[0038] A label is a piece of paper, plastic film, cloth, metal, or other material attached to a container or product, with information or symbols about the product or item written or printed on it. Information directly printed on the container or item can also be regarded as a label. Labels have many uses, including promotion and providing information about the product source, manufacturer (such as brand name), use, safety, shelf life, and disposal. Therefore, a product label is the "identity card" of the product, and it has the important functions of identifying the product, promoting the brand image, and transmitting product information. Label paper is generally mass-produced in rolls. Before using the label paper, workers generally use a cutter to cut the label paper. The traditional method is generally manual cutting. Manual label cutting not only has the problems of long time consumption and high labor intensity, but also has the phenomenon that the label cutting is imperfect and needs to be reprocessed.

[0039] The label cutting device provided in this embodiment can cut any label, such as labels on air conditioners, fans, compressors, and so on.

[0040] The label cutting device provided in this embodiment eliminates quality hazards through the excavation of effective actions in the label cutting process and the transformation and upgrade using an automated method. And combined with automation to achieve automatic label cutting, so as to reduce the labor intensity. While achieving the effectiveness of label cutting, it also achieves the purpose of reducing staff and increasing efficiency.

[0041] In this embodiment, the fixed platform 1 has a cubic structure with a certain thickness. The label feeding reel assembly 2, the cutting assembly 3, and the label winding reel assembly 4 are arranged on the fixed platform 1, and the entire label cutting device can be moved by moving the fixed platform 1. Moreover, the fixed platform 1 is made of a heat-resistant, corrosion-resistant insulating material, such as phenolic plastic sheet. Phenolic plastic, commonly known as bakelite powder, is a hard and brittle thermosetting plastic. The plastics with phenolic resin as the base material are collectively called phenolic plastics, which are the most important type of thermosetting plastics. It has the characteristics of high strength, toughness, wear resistance, dimensional stability, corrosion resistance, and excellent electrical insulation performance.

[0042] The label feeding reel assembly 2 is used to place the uncut label reel; the cutting assembly 3 is used to cut the label; the label winding reel assembly 4 is used to wind and recycle the cut label.

[0043] In the specific use process, a worker takes an uncut label reel and places it at the label feeding reel assembly 2 in the direction with the end facing the driving unit 41. Then, the worker pulls the end of the label reel to make its end pass through the cutting assembly 3. The cutting assembly 3 works to cut the label into two parts. Suppose it is divided into the first part and the second part. Then, the worker pulls the end of the first part to wind it around the label winding reel 42. After that, the driving unit 41 and the cutting assembly 3 work simultaneously to make the first part completely wind around the label winding reel 42. Then, the worker pastes the end of the first part to the head of the second part. The driving unit 41 continues to work until the second part is also completely wound. Of course, after the first part is completely wound, a new label winding reel 42 can also be replaced, and the second part can be wound around the new label winding reel 42. In this way, two reels of cut labels will be obtained after cutting.

[0044] The label cutting device provided in this embodiment relies on simple automation technology to improve the label cutting quality when cutting labels and reduce the judgment of label cutting caused by manual operations. Moreover, it replaces manual operations of employees with automated tooling, reduces the labor intensity, improves the operation efficiency, and improves the product quality.

[0045] In addition, the driving unit 41 in this embodiment is a servo motor. The servo motor mainly relies on pulses for positioning. Basically, it can be understood that when the servo motor receives a pulse, it will rotate by an angle corresponding to the pulse, thereby achieving displacement. Because the servo motor itself has the function of emitting pulses, every time the servo motor rotates by an angle, it will emit a corresponding number of pulses. In this way, it forms a correspondence, or a closed loop, with the pulses received by the servo motor. In this way, the system will know how many pulses are sent to the servo motor and how many pulses are received back. In this way, the rotation of the motor can be accurately controlled, so as to achieve accurate positioning, which can reach 0.001 mm.

[0046] The DC servo motor is adopted in this embodiment, which is divided into brushed and brushless motors. The brushed motor has low cost, simple structure, large starting torque, wide speed regulation range, easy control, requires maintenance, but the maintenance is inconvenient (changing carbon brushes), generates electromagnetic interference, and has requirements for the environment. Therefore, it can be used in general industrial and civil occasions that are sensitive to cost. The brushless motor is small in size, light in weight, large in output, fast in response, high in speed, small in inertia, smooth in rotation, and stable in torque. The control is complex and it is easy to realize intelligence. Its electronic commutation method is flexible and can be square wave commutation or sine wave commutation. The motor is maintenance-free, has high efficiency, low operating temperature, very small electromagnetic radiation, and long service life, and can be used in various environments.

[0047] The servo motor in this embodiment can control the winding speed at the winding component 4, and further control the cutting speed of the cutting component 3, so that the cutting speed matches different label materials.

[0048] In a specific embodiment, the unwinding component 2 includes a support member 21 and a reel fixing shaft 22. The support member 21 is arranged on the fixed table 1, and the reel fixing shaft 22 is connected to the end of the support member 21; the reel fixing shaft 22 is used for placing the label reel before cutting.

[0049] Specifically, the support member 21 is an L-shaped structure, which includes a first plate arranged vertically and a second plate arranged horizontally, and the first plate and the second plate are integrally formed. The second plate is closely attached to the fixed table 1, and the top of the first plate has a notch, and there is a screw at the notch, and the reel fixing shaft 22 is connected to the screw.

[0050] During the specific use process, the uncut label reel is sleeved on the reel fixing shaft 22. Under the action of the driving unit 41, the unwinding component 2 without power can realize unwinding. Specifically, the driving unit 41 drives the reel recovery cylinder 42 to rotate, the reel recovery cylinder 42 drives the label to move, and then the label makes the reel fixing shaft 22 for sleeving the label reel rotate, realizing unwinding; and the driving unit 41 includes a servo motor, and the unwinding speed can also be controlled by controlling the servo motor.

[0051] In a specific embodiment, the unwinding component 2 further includes a first blocking unit 23 movably arranged on the reel fixing shaft 22. Two first blocking units 23 are arranged, and the two first blocking units 23 are respectively located at both ends of the label reel.

[0052] The uncut label reel is sleeved on the reel fixing shaft 22. In order to prevent the label reel from moving axially during the rotation of the reel fixing shaft 22, the first blocking unit 23 is arranged at both ends of the label reel.

[0053] During the specific installation process, first, one of the first blocking units 23 is sleeved on the material roll fixing shaft 22 and is close to the vertical plate. Then, the uncut label roll is sleeved. Finally, the other first blocking unit 23 is sleeved on the material roll fixing shaft 22 and is close to the label roll.

[0054] In a specific embodiment, the first blocking unit 23 includes a first baffle 231 and a first retaining disc 232. In the direction from near the label roll to far from the label roll, the first baffle 231 and the first retaining disc 232 are arranged in sequence.

[0055] Specifically, the first baffle 231 is a circular structure with a fixing hole in the middle. It can be sleeved on the material roll fixing shaft 22 through the fixing hole and has a relatively large area. In this way, when the uncut label roll has a relatively large diameter, the two first baffles 231 can limit the label roll and prevent it from moving axially.

[0056] The first retaining disc 232 is sleeved on the material roll fixing shaft 22, which can prevent the first baffle 231 from moving axially. The first retaining disc 232 can be rotationally matched with the material roll fixing shaft 22 or threadedly matched with the material roll fixing shaft 22, etc.

[0057] In this way, after adopting the above structure, during the unwinding process, the uncut label roll sleeved on the material roll fixing shaft 22 can be cut and wound along the established route without deviation.

[0058] In a specific embodiment, the cutting assembly 3 includes a fixed seat 31, a cutting knife, and a pressing unit 32. The fixed seat 31 is arranged on the fixed table 1. The pressing unit 32 is connected to the top of the fixed seat 31. The cutting knife is located above the pressing unit 32 and is used to cut the label when the pressing unit 32 presses the label.

[0059] Specifically, the fixed seat 31 includes a bottom plate, a front panel, and two side plates. The bottom plate is horizontally arranged, and a vertically arranged front panel is connected to one side. Vertical side plates are respectively arranged at both ends of the bottom plate, and the two side plates are respectively connected to both sides of the front panel. Moreover, the shape of the side plates is similar to a triangle, which can ensure the stability of the fixed seat 31.

[0060] The pressing unit 32 is fixed on the front panel, and the cutting knife is movably arranged on the pressing unit 32.

[0061] The cutting knife is made of stainless steel, which is tough and does not chip. Stainless steel is defined in accordance with GB / T 20878-2007 as steel with mainly stainless and corrosion-resistant properties, and the chromium content is at least 10.5%, and the carbon content does not exceed 1.2% at most.

[0062] Stainless steel is short for stainless acid-resistant steel. Steel types that are resistant to weak corrosive media such as air, steam, and water or have rust resistance are called stainless steels; while steel types that are resistant to chemical corrosive media are called acid-resistant steels. Due to the differences in their chemical compositions, their corrosion resistances are different. Ordinary stainless steels are generally not resistant to chemical media corrosion, while acid-resistant steels generally have rust resistance. The term "stainless steel" does not simply refer to a single type of stainless steel, but represents more than a hundred industrial stainless steels. Each developed stainless steel has good performance in its specific application field. The key to success is first to clarify the use, and then determine the correct steel type. There are usually only six steel types related to the application field of building structures. They all contain 17-22% chromium, and better steel types also contain added molybdenum to further improve atmospheric corrosion resistance, especially corrosion resistance to chloride-containing atmospheres. Generally speaking, the hardness of stainless steel is higher than that of aluminum alloy, and the cost of stainless steel is higher than that of aluminum alloy.

[0063] In a specific embodiment, the pressing unit 32 includes a first pressing shaft 321, a second pressing shaft 322, and a third pressing shaft 323. From the direction close to the unwinding roll assembly 2 to the direction away from the unwinding roll assembly 2, the first pressing shaft 321, the second pressing shaft 322, and the third pressing shaft 323 are arranged in sequence. The labels pass under the first pressing shaft 321, above the second pressing shaft 322, and under the third pressing shaft 323 in sequence and then are wound around the winding roll assembly 4.

[0064] Specifically, one ends of the first pressing shaft 321, the second pressing shaft 322, and the third pressing shaft 323 are all fixed on the front panel.

[0065] In a specific embodiment, the pressing unit 32 further includes a fourth pressing shaft 324. A pressing piece 325 is arranged on the fourth pressing shaft 324, and the pressing piece 325 can press the label on the second pressing shaft 322; the cutting knife is arranged on the fourth pressing shaft 324.

[0066] In addition, in order to ensure the stability of the structure, after one end of the fourth pressing shaft 324 is fixed on the front panel, the other end thereof is connected to the other end of the second pressing shaft 322 through a connecting block 327.

[0067] In the above embodiment, along the direction from unwinding to winding, the first pressing shaft 321, the fourth pressing shaft 324, the second pressing shaft 322, and the third pressing shaft 323 are arranged in sequence, and the first pressing shaft 321, the fourth pressing shaft 324, the second pressing shaft 322, and the third pressing shaft 323 are at different heights.

[0068] Of course, more pressing shafts can also be provided to optimize the transmission of the labels.

[0069] In addition, a pressing piece 325 is sleeved on the fourth pressing shaft 324. The pressing piece 325 faces the second pressing shaft 322 and can press the label on the second pressing shaft 322, facilitating the cutting by the cutting knife at this time.

[0070] In a specific embodiment, in order to ensure that the label is pressed when cutting the label, two pressing pieces 325 are provided, and a synchronizing shaft for ensuring the synchronous movement of the two pressing pieces 325 is connected between the two pressing pieces 325; the cutting knife is movably arranged between the two pressing pieces 325.

[0071] In a specific embodiment, first blocking pieces 326 for limiting the label are arranged at both ends of the first pressing shaft 321;

[0072] The first blocking piece 326 is a circular structure with a through hole, and it is sleeved on the first pressing shaft 321 through the through hole to prevent the label from deviating from the preset path.

[0073] In a specific embodiment, second blocking pieces for limiting the label are arranged at both ends of the second pressing shaft 322.

[0074] The second blocking piece is a circular structure with a through hole, and it is sleeved on the second pressing shaft 322 through the through hole to prevent the label from deviating from the preset path.

[0075] In a specific embodiment, the material receiving reel assembly 4 further includes a second blocking unit 44 movably arranged on the output shaft 43 of the driving unit 41. Two second blocking units 44 are provided, and the two second blocking units 44 are respectively located at both ends of the label roll.

[0076] The label roll in this embodiment refers to the label roll on the material roll recovery cylinder 42.

[0077] When the empty label roll, that is, the material roll recovery cylinder 42, is sleeved on the output shaft 43 of the driving unit 41, in order to prevent the label roll from moving axially during the rotation of the material roll recovery cylinder 42, second blocking units 44 are arranged at both ends of the label roll.

[0078] During the specific installation process, first, one of the second blocking units 44 is sleeved on the output shaft 43 of the driving unit 41, then the material roll recovery cylinder 42 is sleeved, and finally the other second blocking unit 44 is sleeved on the output shaft 43 of the driving unit 41.

[0079] The second blocking unit 44 includes a second blocking piece 441 and a second blocking disk 442. From the direction close to the label roll to the direction away from the label roll, the second blocking piece 441 and the second blocking disk 442 are arranged in sequence.

[0080] Specifically, the second baffle 441 has a circular structure with a fixing hole in the middle. It can be sleeved on the output shaft 43 of the driving unit 41 through the fixing hole, and it has a relatively large area. In this way, when the cut labels are wound more to form a label roll with a larger diameter, the two second baffles 441 can limit the label roll to prevent it from moving axially.

[0081] The second retaining disc 442 is sleeved on the output shaft 43 of the driving unit 41, which can prevent the second baffle 441 from moving axially; the second retaining disc 442 can be rotationally matched with the output shaft 43 of the driving unit 41, or can be threadedly matched with the output shaft 43 of the driving unit 41, etc.

[0082] The specific working process of the label cutting device provided in this embodiment is as follows:

[0083] An operator takes a roll of uncut labels, places it at the unwinding roll assembly 2 in the direction with the end facing the driving unit 41, installs the first blocking unit 23 and tightens it, pulls the label forward and passes it under the first pressing shaft 321, then lifts the cutting knife and the pressing piece 325, passes the label under the fourth pressing shaft 324 and above the second pressing shaft 322, places the cutting knife at the center position of the label and then releases the cutting knife, and then pulls the label through under the third pressing shaft 323 and winds it around the material roll recovery cylinder 42, tapes the label tightly to the material roll recovery cylinder 42, installs the second blocking unit 44 and tightens it, turns on the switch of the servo motor, and then the label cutting can run normally.

[0084] After the whole roll of labels is cut and the labels are divided into two parts, the first part of the labels has been wound around the material roll recovery cylinder 42. Then, the end of the first part of the labels is pasted to the head of the second part of the labels, and the servo motor continues to work until the second part of the labels is also wound. Of course, after the first part of the labels is wound, a new material roll recovery cylinder 42 can also be replaced, and the second part of the labels can be wound around the new material roll recovery cylinder. In this way, two rolls of cut labels will be obtained after cutting.

[0085] The label cutting device provided in this embodiment excavates the effective actions in the manual label cutting process, and uses the method of a simple tooling electric mechanism to rotate and cut the labels for transformation and upgrade, eliminates quality hidden dangers, and avoids the occurrence of major after-sales accidents.
