[0085] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0086] like Figure 3 and Figure 4 As shown, a multi-color ironing machine head includes an ironing color changing component 3, an ironing driving component 4, an ironing disc component 5 and an ironing needle bar component 6.

[0087] like Figure 8 As shown, the ironing sheet driving assembly 4 includes a film strip driving assembly 41 and a needle bar driving assembly 42. The film strip driving assembly 41 is used to drive the film strip of the corresponding color to move forward. The needle bar driving assembly 42 is used to drive the corresponding needle bar to perform an up and down reciprocating motion to punch the corresponding film strip into a desired film sheet. The present application does not limit the structure of the needle bar driving assembly 42, and the needle bar driving assembly 42 can adopt any structure of the needle bar driving assembly 42 in the prior art.

[0088] like Fig. 9In combination with FIG. 8 , the membrane belt driving assembly 41 includes a driving motor 1 411 , a driving motor 2 412 , a motor seat A 413 , a motor seat B 414 , a rivet A 414 - 1 , a rivet B 414 - 2 , a disengageable eccentric sleeve 416 , a motor seat torsion spring 415 , a screw 414 - 3 , a driving wheel seat 411 - 1 , a driving wheel 419 and a driving wheel pressure plate 418 .

[0089] The housing of the second drive motor 412 is connected and fixed to the frame of the needle bar drive assembly 42, the motor seat A413 is connected and fixed to the housing of the second drive motor 412, and the motor seat B414 is connected and fixed to the housing of the first drive motor 411. The motor seat B414 is riveted to the motor seat A413 by rivets A414-1 and rivets B414-2, and the motor seat B414 is also provided with a guide groove that cooperates with the rivet A414-1. That is, rivet A414-1 and rivet B414-2 are connected and fixed with motor base A413, motor base B414 is movably connected with the rod of rivet B414-2 through the connecting hole and the rod of rivet A414-1 through the guide groove, and motor base B414 can rotate along rivet B414-2. During the rotation of motor base B414, motor base B414 will perform adaptive position adjustment relative to the rod of rivet A414-1 through the guide groove. During the forward and reverse rotation of motor base B414, the position of driving motor 1 411 will be driven to change accordingly.

[0090] The driving wheel seat 411-1 includes a seat plate and a support body. The output shaft of the driving motor 411 is inserted from the central axis position on one side of the seat plate of the driving wheel seat 411-1 and is connected and fixed to the support body by fastening screws. The driving wheel 419 is sleeved on the support body of the driving wheel seat 411-1. The driving wheel pressure plate 418 is connected and fixed to the shaft end of the support body. The driving wheel 419 is connected and fixed to the driving wheel seat 411-1 through the driving wheel pressure plate 418 and the seat plate. When the driving motor 411 is started, its output shaft will rotate, thereby driving the driving wheel seat 411-1 and the driving wheel 419 to rotate accordingly. When the motor seat B414 rotates in the forward direction to a certain extent, it will drive the position of the driving motor 411 to change accordingly, so that the driving wheel 419 can just match Fig.10 The hot plate bearing 66 is in contact with the hot plate bearing 66 in the hot plate, and when the driving wheel 419 rotates, it can drive the hot plate bearing 66 to rotate, and the film belt is located between the hot plate bearing 66 and the hot plate driven wheel 65. The rotation of the hot plate bearing 66 will drive the film belt forward. When the motor seat B414 rotates in the reverse direction to a certain extent, it will drive the position of the driving motor 411 to change accordingly, so that the driving wheel 419 and the film belt are connected. Fig.10 The hot plate bearing 66 is separated.

[0091] The disengagement eccentric sleeve 416 is connected and fixed to the output shaft of the second drive motor 412 by a fastening screw, and the motor base B414 is also provided with a swing arm that is in contact with the outer peripheral side of the disengagement eccentric sleeve 416. When the second drive motor 412 starts its output shaft to rotate forward and reverse, the disengagement eccentric sleeve 416 will perform corresponding forward and reverse rotations. Since the disengagement eccentric sleeve 416 is eccentrically arranged, the radius of the contact position between it and the swing arm of the motor base B414 will change, so that the swing arm will swing, and then the entire motor base B414 can rotate forward and reverse along the rivet B414-2. The motor base torsion spring 415 is connected and fixed to the rod of the rivet B414-2 and one end is connected to the screw 414-3 arranged on the motor base B414. Through the arrangement of the motor base torsion spring 415, the rotation of the motor base B414 can be made more stable and reliable.

[0092] The film belt driving assembly 41 of the structure of the present application can enable the driving wheel 419 to have a continuous and stable output pressure, effectively improving the smoothness of the film belt positioning, thereby improving the working efficiency of the ironing machine.

[0093] The film belt drive assembly 41 also includes an origin limit block 417 and a set screw 416-1. The origin limit block 417 is connected to the motor seat A413, and the set screw 416-1 is radially connected to the outer periphery of the detached eccentric sleeve 416 and is cooperatively connected to the origin limit block 417. When the motor seat B414 rotates to make the driving wheel 419 effectively contact the hot plate bearing 66, the set screw 416-1 just contacts the origin limit block 417, which plays a limiting and positioning effect, further improving the stability of the output pressure of the driving wheel 419, thereby further improving the smoothness of the film belt positioning.

[0094] like Figure 5 Combined with Figure 4 , Fig.10 As shown, the color-changing component 3 of the ironing sheet includes a color-changing motor bracket 34, a color-changing cam 33, a color-changing motor 32, a color-changing potentiometer 35, a color-changing ball plate 62 and a color-changing pin 61. The color-changing motor bracket 34 is connected to the top of the frame of the ironing sheet driving assembly 4, and the color-changing cam 33 is arranged between the two color-changing motor brackets 34, and the color-changing cam 33 is provided with a limiting wheel groove. The housing of the color-changing motor 32 is connected to one of the color-changing motor brackets 34, and one end of its output shaft is connected through the color-changing cam 33. The color-changing potentiometer 35 is connected to the same end of the output shaft of the color-changing motor 32, and is used to record the rotation position of the color-changing motor 32 (i.e., the color-changing cam 33). The color-changing ball plate 62 is connected to the frame of the ironing sheet needle bar assembly 6. The color-changing pin 61 is connected to the color-changing ball plate 62 and is matched with the limiting wheel groove of the color-changing cam 33. One color-changing pin 61 corresponds to the setting position of one film strip.

[0095] The present application can arrange multiple groups of film strips of different colors side by side, and each group of film strips is equipped with a corresponding needle bar frame 67 and a sheet ironing bearing 66. A guide rail is arranged on the frame of the sheet ironing drive assembly 4, and a guide shoe is arranged on the frame of the sheet ironing needle bar assembly 6. The guide rail and the guide shoe can make the sheet ironing needle bar assembly 6 move left and right relative to the sheet ironing drive assembly 4 along the direction in which the guide rail is arranged.

[0096] When the film strip needs to be changed in color, the film strip drive assembly 41 can be separated from the ironing sheet bearing 66 corresponding to the current color film strip, and the needle bar drive assembly 42 can be separated from the needle bar frame 67 corresponding to the current color film strip, and then the position of the ironing sheet needle bar assembly 6 on the guide rail can be adjusted so that the ironing sheet bearing 66 and the needle bar frame 67 corresponding to the next color film strip can be docked with the film strip drive assembly 41 and the needle bar drive assembly 42. After the position of the ironing sheet needle bar assembly 6 is adjusted, the color-changing motor 32 can be controlled to start so that the color-changing cam 33 rotates. During the rotation of the color-changing cam 33, its limiting wheel groove will be limited and fixed with the color-changing pin 61 corresponding to the next color film strip, so that the position of the ironing sheet needle bar assembly 6 relative to the ironing sheet drive assembly 4 is fixed, so that the film strip can be punched. When the film strip needs to be changed in color again, the color-changing cam 33 can be driven to rotate by the color-changing motor 32 to separate its limiting wheel groove from the color-changing pin 61 corresponding to the current color film strip, and then the position of the ironing needle bar assembly 6 on the guide rail is adjusted again so that the color-changing pin 61 corresponding to the next color film strip can be engaged with the color-changing cam 33.

[0097] The color-changing component 3 of the ironing sheet of the present application is simple in structure and easy to operate, and can quickly adjust the position of the ironing sheet needle bar assembly 6 and limit and fix it, making the color-changing operation of the ironing sheet machine of the present application extremely simple.

[0098] The ironing sheet color changing component 3 also includes a color changing hand wheel 31 connected to the other shaft end of the output shaft of the color changing motor 32. When the color changing motor 32 fails or in other situations, the user can directly rotate the color changing cam 33 through the color changing hand wheel 31 to connect, fix or separate the ironing sheet needle rod assembly 6 and the ironing sheet driving assembly 4, further improving the color changing convenience of the ironing sheet machine of the present application.

[0099] like Figure 6 and Figure 7 Combined with Figure 3As shown, the film ironing disc assembly 5 includes a disc mounting plate 57, a disc seat 51, a material disc 54, a disc mounting bracket 53, a bearing 56, a film ironing tensioning wheel 55, a film ironing tensioning torsion spring 52, a film passing shaft 1 58 and a film passing shaft 2 59. The disc mounting plate 57 is connected to the top of the frame of the film ironing needle bar assembly 6, and the disc seat 51 is symmetrically provided with two, both connected to the top of the disc mounting plate 57. A plurality of material discs 54 are coaxially installed, and each material disc 54 is used to wind and store a film tape of a color. The material disc mounting bracket 53 is arranged between two adjacent material discs 54 and is provided with an axis mounting hole 1 coaxially connected to the material disc 54. The material disc mounting bracket 53 is also provided with an axis mounting hole 2 and an axis mounting hole 3, and the axis mounting hole 1, the axis mounting hole 2 and the axis mounting hole 3 are arranged in an isosceles triangle. The shaft mounting holes 2 of all the tray mounting brackets 53 are connected through shaft body 2, and the shaft mounting holes 3 of all the tray mounting brackets 53 are connected through shaft body 3. The axial ends of shaft body 3 are connected to the disc seat 51. The bearing 56 is connected to shaft body 2 or shaft body 3 and is arranged between two adjacent tray mounting brackets 53. The bearing 56 plays a role of spacing support on the one hand, and plays a role of film belt guidance on the other hand.

[0100] The sheet-heating tensioning wheel 55 is connected to the shaft body 1, and the axial ends of the shaft body 1 are connected to the sheet disc seat 51. The sheet-heating tensioning torsion spring 52 is sleeved on the shaft body 1 between the two sheet-heating tensioning wheels 55 at intervals, and one end of the torsion spring is connected to the corresponding sheet-heating tensioning wheel 55. The sheet-heating tensioning wheel 55 and the sheet-heating tensioning torsion spring 52 are arranged in coordination to keep the film tape at a certain tensioning force, which is not easy to loosen, thereby improving the guiding effect of the film tape. The axial ends of the film-passing shaft 1 58 are connected to the sheet-heating sheet disc seat 51, and the axial ends of the film-passing shaft 2 59 are connected to the sheet-heating sheet disc seat 51. When the film tape moves forward, it passes between the film-passing shaft 1 58 and the film-passing shaft 2 59, which can prevent the film tape from being disordered and make it proceed effectively in a certain order, thereby further improving the guiding effect of the film tape.

[0101] In the film ironing disc assembly 5 of the present application, the film belt passes through the bearing 56 of the shaft body 3 of the material disc 54, then passes horizontally between the film passing shaft 1 58 and the film passing shaft 2 59, and finally moves downward through the film ironing tensioning wheel 55. The film ironing disc assembly 5 of the present application has a good guiding effect, preventing the film belt from deviating during the moving process, thereby improving the working efficiency of the film ironing machine.

[0102] like Fig.10 As shown, the ironing needle bar assembly 6 includes a needle bar frame 67, an ironing support plate 64, an ironing mold frame 61-1, an ironing mold frame 61-1, an ironing die assembly 69-4, an ironing bearing 66, an ironing driven wheel 65, an ironing sheet outlet guide plate 63, an ironing sheet upper panel 69-5, an ironing sheet lower panel 69-6, a film passing shaft three 69-7, a film passing shaft four and a film passing shaft five.

[0103] The sheet ironing support plate 64 is connected to the bottom of both sides of the needle bar frame 67. The sheet ironing mold frame 61-1 is connected to the bottom of the needle bar frame 67 through the mold frame pad 69-8, and the mold frame pad 69-8 has a positioning function. The sheet ironing die assembly 69-4 is detachably connected to the sheet ironing mold frame 61-1 through the die pressing block 69-9, and the die pressing block 69-9 is used to press the sheet ironing die assembly 69-4 and the sheet ironing mold frame 61-1 tightly, so that the connection between the two is very stable, thereby improving the sheeting effect of the film strip.

[0104] The sheet ironing bearing 66 is connected to the shaft body 4 and is connected to the driving wheel 419. The two axial ends of the shaft body 4 are connected to the sheet ironing support plate 64. The number and position of the sheet ironing bearing 66 correspond to the number and position of the material tray 54. The sheet ironing driven wheel 65 is connected to the shaft body 5. The two axial ends of the shaft body 5 are connected to the sheet ironing support plate 64. The number and position of the sheet ironing driven wheel 65 correspond to the number and position of the sheet ironing bearing 66. The sheet ironing sheet outlet guide plate 63 is connected to the sheet ironing support plate 64. The sheet ironing sheet outlet guide plate 63 is provided with a film strip outlet. After the film strip comes out of the gap between the sheet ironing bearing 66 and the sheet ironing driven wheel 65, it directly enters the corresponding film strip outlet to facilitate the outlet of the waste film strip. The upper ironing panel 69-5 is connected to the upper front part of the needle bar frame 67, the lower ironing panel 69-6 is connected to the lower front part of the needle bar frame 67, and the two axial ends of the film-passing shaft 3 69-7 are connected to the positions on both sides of the needle bar frame 67 located on the upper ironing panel 69-5. The two axial ends of the film-passing shaft 4 are connected to the two axial ends of the film-passing mold frame 61-1, and the two axial ends of the film-passing shaft 5 are connected to the two axial ends of the film-passing mold frame 61-1. A guide gap is formed between the film-passing shaft 4 and the film-passing shaft 5 to allow the film tape to pass through.
