[0002] Coating machines are mainly used for surface coating production of films, paper, etc. This machine coats the rolled substrate with a layer of glue, paint or ink with specific functions, and then cuts it into sheets or rolls it up after drying, which can give the material new properties.

[0003] The patent for the flying knife sliding cutting automatic material connection mechanism for coating machines (Announcement No.: CN 116835366 B) has been authorized, which belongs to the field of coating technology. The flying knife sliding cutting automatic material connection mechanism arranged on the unwinding frame includes: a connecting component rotatably arranged on the unwinding frame, the two ends of the driving component are respectively connected to the unwinding frame and the connecting component, and drive the connecting component to rotate; the cutting support roller is rotatably arranged on the connecting component; and the flying knife component is arranged on the connecting component, the flying knife component is arranged in parallel with the cutting support roller, the linear driving source drives the cutting blade to reciprocate.

However, it adopts manual splicing and bonding in the splicing process, which is prone to the problem of poor bonding flatness.

[0004] The patent for an automatic winding and material splicing mechanism of a coating machine (Announcement No.: CN207078778U) has been authorized, which discloses an automatic winding and material splicing mechanism of a coating machine, including a winding reel mounted on the wallboard of the coating machine and a rubber pressure roller cooperating with the winding reel and used to press the diaphragm onto the winding reel, and also includes a diaphragm cutting assembly, the diaphragm cutting assembly includes a cutter advance and retreat cylinder and a cutter advance and retreat guide rail mounted on the wallboard of the coating machine, a cutter advance and retreat mounting plate that can slide on the cutter advance and retreat guide rail is mounted on the cutter advance and retreat cylinder can drive the cutter advance and retreat mounting plate to slide on the cutter advance and retreat guide rail, a cutter action cylinder is mounted on the cutter advance and retreat mounting plate, a cutter action cylinder is provided at the output end of the cutter action cylinder, and a diaphragm cutter is mounted on the cutter mounting plate. The automatic winding and material splicing mechanism of the coating machine has advantages that the prior art does not have, such as good winding effect and prevention of bottom wrinkles.

[0005] Although the above-mentioned prior art realizes the cutting of the film material before replacing the winding roller, the replaced winding roller needs to be fixed to the film material, and the existing method of manual fixation with double-sided tape is prone to bubbles, unevenness and poor bonding strength at the bonding point, resulting in an uneven material head on the winding roller and easy wrinkling of the winding core. Summary of the invention

[0006] The object of the present invention is to provide a flying knife static material receiving mechanism and a material receiving method thereof, so as to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a flying knife static material receiving mechanism, comprising a frame and a winding roller detachably mounted on the frame and driven to rotate by a driving source mounted on the frame; further comprising a movable frame on which a pressure roller and a cutting assembly are mounted; a swing arm mechanism mounted on the frame for controlling the cutting assembly and the pressure roller to move toward or away from the winding roller; a control system, establishing communication with the driving source and the swing arm mechanism, for controlling the movement of the swing arm mechanism to bring the pressure roller into contact with the winding roller after replacing the winding roller, and controlling the driving source to drive the winding roller to rotate in the opposite direction of winding and then in the winding direction.

[0008] The flying knife static material receiving mechanism as described above: the swing arm mechanism includes: a receiving frame, which has two connecting positions formed along its length direction; a telescopic driving member, which is fixed at one of the connecting positions of the receiving frame, and the movable end of the telescopic driving member is connected to the movable frame; a rotating driving member, which is installed on the frame and connected to the other connecting position of the receiving frame, and is used to drive the receiving frame to rotate.

[0009] The flying knife static material receiving mechanism as described above: the rotating driving member includes a swing shaft rotatably mounted on the frame, the receiving frame is fixed on the swing shaft, both ends of the swing shaft are fixed with connecting arms, and the connecting arms are hinged to the movable end of the cylinder rotatably mounted on the frame.

[0010] The flying knife static material receiving mechanism as described above: the cutting assembly includes: a linear drive installed on the movable frame and with a length direction parallel to the axial direction of the winding roller, and a cutting knife is installed at the movable end of the linear drive.

[0011] The flying knife static material receiving mechanism as described above: a guide roller is also rotatably mounted on the movable frame, and the film material passing through the pressure roller bypasses the guide roller and is connected to the winding roller.

[0012] The flying knife static material receiving mechanism as described above: the cutting knife is located between the pressing roller and the guide roller.

[0013] The flying knife static material receiving mechanism as described above: the control system includes a detection unit, the detection unit establishes communication with the driving source, and is used to detect the position of the double-sided tape placed on the winding roller, and control the driving source to drive the winding roller to rotate according to the position of the double-sided tape, so as to keep the winding roller with the double-sided tape placed facing directly upwards.

[0014] A flying knife static material receiving method, using the above-mentioned flying knife static material receiving mechanism, comprises the following steps: S1. After the winding roller is wound up, the swing arm mechanism drives the pressure roller to contact the winding roller, and drives the cutting assembly to cut the film material; S2, then control the swing arm mechanism to reset, remove the winding roller and install a new winding roller on the frame, and control the double-sided tape pasted on the winding roller to face upward, and manually paste the head of the film material on the double-sided tape; S3, the control system controls the swing arm mechanism to drive the pressure roller to contact the winding roller again, and then controls the driving source to drive the winding roller to rotate in the opposite direction of winding, so as to level the material head and the double-sided tape pasting position, and then controls the driving source to drive the winding roller to perform the winding action.

[0015] Compared with the prior art, the beneficial effect of the present invention is that after the winding roller is completed, the swing arm mechanism controls the cutting assembly and the pressure roller to move toward the winding roller, so that the pressure roller abuts against the winding roller, and then the cutting assembly cuts the film material. The set pressure roller can prevent the film material from being cut and deformed due to tension during the disassembly process of the film material. Secondly, it can prevent the film material wound on the winding roller from becoming loose.

[0016] When replacing the winding roller, the swing arm mechanism controls the pressure roller and the cutting assembly to reset, then the winding roller with the film material is removed and a new winding roller is installed, the material head of the film material is manually bonded to the double-sided tape on the winding roller, the control system controls the movement of the swing arm mechanism to make the pressure roller and the winding roller abut, and controls the driving source to drive the winding roller to rotate in the opposite direction of winding, thereby squeezing and flattening the artificially bonded material head, eliminating bubbles or uneven bonding that exist in artificial bonding, and ensuring that subsequent winding can eliminate the problems of core wrinkles and winding offset.

[0019] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0020] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0021] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0022] See also Figure 1-Figure 5In an embodiment of the present invention, a flying knife static material receiving mechanism comprises a frame 1 and a winding roller 11 detachably mounted on the frame 1 and driven to rotate by a driving source 5 mounted on the frame 1; it also comprises a movable frame 13, on which a pressure roller 12 and a cutting assembly are mounted. Preferably, the movable frame 13 is provided with two, and the rotating shafts at both ends of the pressure roller 12 are rotatably connected to the two movable frames 13, and the cutting assembly is fixed between the two movable frames 13; a swing arm mechanism is mounted on the frame 1 and is used to control the cutting assembly and the pressure roller 12 to move toward or away from the winding roller 11; a control system establishes communication with the driving source 5 and the swing arm mechanism and is used to control the swing arm mechanism to move the pressure roller 12 to abut against the winding roller 11 after replacing the winding roller 11, and control the driving source 5 to drive the winding roller 11 to rotate in the opposite direction of winding and then rotate in the winding direction.

[0023] In this embodiment, after the winding roller 11 completes winding, the swing arm mechanism controls the cutting assembly and the pressure roller 12 to move toward the winding roller 11, so that the pressure roller 12 abuts against the winding roller 11, and then the cutting assembly cuts the film material. The setting of the pressure roller 12 can prevent the film material from being cut and deformed due to tension during the disassembly of the film material. Secondly, it can prevent the film material wound on the winding roller 11 from becoming loose.

[0024] When the winding roller 11 is replaced, the swing arm mechanism controls the pressure roller 12 and the cutting assembly to reset, then the winding roller 11 with the film material rolled up is removed and a new winding roller 11 is installed, the material head of the film material is manually bonded to the double-sided tape on the winding roller 11, the control system controls the swing arm mechanism to move the pressure roller 12 and the winding roller 11, and controls the driving source 5 to drive the winding roller 11 to rotate in the opposite direction of winding, thereby squeezing and flattening the artificially bonded material head, eliminating bubbles or uneven bonding that exist in artificial bonding, and ensuring that subsequent winding can eliminate the problems of core wrinkles and winding offset.

[0025] After the pressure roller 12 abuts against the winding roller 11 and rotates to level the material head, the control system controls the driving source 5 to drive the winding roller 11 to rotate along the normal winding direction to start a new winding process. Through automated control, not only the efficiency of film material winding is improved, but also the quality of winding is ensured, winding problems caused by improper manual operation are avoided, and the stability and reliability of the production line are greatly improved.

[0026] See also Figure 1-Figure 7The swing arm mechanism includes a receiving frame 3, which is in the shape of a long plate and is provided with two receiving frames 3. The two receiving frames 3 are fixed by a fixing frame. The receiving frame 3 has two connecting positions along its length direction, one of which is fixed with a telescopic driving member 4. The movable end of the telescopic driving member 4 is connected to the movable frame 13, and the other connecting position is connected to the rotating driving member installed on the frame 1.

[0027] For the sake of convenience, the connection position for connecting the telescopic driving member 4 is defined as connection position a, and the connection position for connecting the rotating driving member is defined as connection position b. The rotating driving member drives the receiving frame 3 to rotate along the connection position b, so that the receiving frame 3 drives the telescopic driving member 4 to rotate as a whole to achieve the swing drive requirement.

[0028] The telescopic driving component 4 described above includes but is not limited to a cylinder, an electric push rod, etc., and is not specifically limited in this embodiment as long as it meets the driving requirements.

[0029] Exemplarily, in one embodiment, the rotating driving member includes a swing shaft 2 rotatably mounted on the frame 1, the supporting frame 3 is fixed on the swing shaft 2, and connecting arms 6 are fixed at both ends of the swing shaft 2, and the connecting arms 6 are hinged to the movable end of the cylinder 7 rotatably mounted on the frame 1.

[0030] When the cylinder 7 is telescopically moved, it drives the swing shaft 2 to rotate through the connecting arm 6, thereby driving the receiving frame 3 to rotate, thereby realizing the driving requirement.

[0031] For further information, see Figure 3-Figure 5 The cutting assembly includes a linear drive 8 installed on the movable frame 13 and with a length direction parallel to the axial direction of the winding roller 11. A cutting knife 9 is installed at the movable end of the linear drive 8. The linear drive 8 is used to drive the cutting knife 9 to move, thereby cutting the film material. Trigger switches are installed at both ends of the linear drive 8. When the cutting knife 9 moves and contacts the trigger switch, the linear drive 8 stops working, thereby allowing the cutting knife 9 to complete a cutting action.

[0032] For further information, see Figure 3 A guide roller 10 is also rotatably installed on the movable frame 13. The film material passing through the pressure roller 12 bypasses the guide roller 10 and is connected to the winding roller 11. The cutting knife 9 is located between the pressure roller 12 and the guide roller 10. The guide roller 10 can be used to guide the film material on the one hand, and on the other hand, the tension of the film material and the fit with the cutting knife 9 can be maintained when the cutting knife 9 performs the cutting action.

[0033] Furthermore, the control system includes a detection unit, which establishes communication with the driving source 5, and is used to detect the position of the double-sided tape placed on the winding roller 11, and control the driving source 5 to drive the winding roller 11 to rotate according to the position of the double-sided tape, so as to keep the winding roller 11 with the double-sided tape placed facing upward, so that the rotation angle of the winding roller 11 in the opposite direction of winding driven by the driving source 5 is relatively constant and easy to control.

[0034] As another embodiment of the present invention, a flying knife stationary material receiving method is also proposed, which adopts the above-mentioned flying knife stationary material receiving mechanism, and includes the following steps: S1. After the winding roller 11 is wound, the swing arm mechanism drives the pressure roller 12 to contact the winding roller 11, and drives the cutting assembly to cut the film material; S2, then control the swing arm mechanism to reset, remove the winding roller 11 and install a new winding roller 11 on the frame 1, and control the double-sided tape pasted on the winding roller 11 to face upward, and manually paste the head of the film material on the double-sided tape; S3, the control system controls the swing arm mechanism to drive the pressure roller 12 to contact the winding roller 11 again, and then controls the driving source 5 to drive the winding roller 11 to rotate in the opposite direction of winding, so as to level the material head and the double-sided tape pasting position, and then controls the driving source 5 to drive the winding roller 11 to perform the winding action.

[0035] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
