Description

Technical field:

[0002] The invention relates to an automatic double-sided flat press machine for ribbon thermal sublimation and a working method thereof. Background technology:

[0004] In the webbing industry, it is usually necessary to heat transfer patterns, logos, text, etc. to both sides of the webbing. At present, the most widely used webbing transfer machine in the industry is the cylindrical transfer machine. Its working principle is: two large rollers are heated at high temperature, and the webbing, padding paper and transfer paper pass through the rollers. The wool felt increases friction and conducts heat to complete the transfer of one side of the webbing. After that, the webbing is turned over and misaligned, and passes through the high-temperature roller again to complete the transfer of the reverse side. The transferred webbing is transferred to the frame through the belt wheel. However, this thermal transfer method has the following shortcomings: (1) Two transfers are required, and the position and size of the double-sided patterns, logos, texts, etc. cannot be guaranteed to be symmetrical, so the quality of the processed product is poor; (2) Since padding paper is used during thermal transfer, it causes material waste.

[0044] like Figures 1 to 12As shown, the present invention is an automatic double-sided flat press for thermal sublimation of ribbon, comprising a frame 1, a hot pressing mechanism 2 installed on the frame 1, a reeling and unreeling mechanism 3 and a turning roller 4, the hot pressing mechanism 2 comprises two hot pressing units 5 symmetrically arranged at the upper and lower parts, the two hot pressing units 5 can move synchronously toward or away from each other in the vertical direction, a hot pressing section 6 is provided between the two hot pressing units 5 to facilitate the passage of the ribbon, and the thickness of the hot pressing section is the thickness of the ribbon; the reeling and unreeling mechanism 3 and the turning roller 4 are respectively arranged on the front and rear sides of the hot pressing section 5, the transfer paper 7 outputted from the unreeling end of the reeling and unreeling mechanism 3 bypasses the upper end of the hot pressing section 6, the turning roller 4 and the lower end of the hot pressing section 6 in turn, and then connects to the reeling end of the reeling and unreeling mechanism 3; a ribbon input mechanism 8 is provided on the left side of the hot pressing mechanism 2, and a pulling mechanism 9 is provided on the right side of the hot pressing mechanism 2 for pulling the ribbon to pass through the hot pressing section in the horizontal direction. During operation, the webbing passes through the hot pressing zone, and the two hot pressing units move toward each other. The hot pressing units clamp the transfer paper and webbing on the upper and lower sides of the hot pressing zone, completing the double-sided transfer operation of the webbing at one time. After that, the pulling mechanism pulls the area on the webbing where the transfer operation is completed out of the hot pressing zone, and the area on the webbing to be transferred is pulled into the hot pressing zone, waiting for the next double-sided transfer operation.

[0045] In this embodiment, an upper pressing roller group and a lower pressing roller group are arranged in parallel up and down between the two hot pressing units 5, and a hot pressing zone 6 is formed between the upper pressing roller group and the pressing roller group to facilitate the passage of the webbing. The upper pressing roller group includes two upper pressing rollers 10 symmetrically arranged on the front and rear sides of the hot pressing mechanism 2, and the lower pressing roller group includes two lower pressing rollers 11 symmetrically arranged on the front and rear sides of the hot pressing mechanism 2 and corresponding to the positions of the two upper pressing rollers 10 one by one; the unwinding mechanism 3 includes an unwinding roller 12 and a winding roller 13 located below the unwinding roller 12, the unwinding roller 12 is the unwinding end of the unwinding mechanism 3, and the winding roller 13 is the winding end of the unwinding mechanism 3. A unwinding transition roller group 14 is provided between the roller 12 and the upper pressure roller group, and a winding transition roller group 15 is provided between the winding roller 13 and the lower pressure roller group. The output end of the transfer paper 7 installed on the unwinding roller 12 successively bypasses the unwinding transition roller group 14, the lower side surfaces of the two upper pressure rollers 10, the turning roller 4, the upper side surfaces of the two lower pressure rollers 11 and the winding transition roller group 15 and is then connected to the winding roller 13. The transfer paper 7 is folded when it bypasses the turning roller 4, that is, the transfer surface of the transfer paper 7 that has not bypassed the turning roller 4 faces downward, and the transfer surface of the transfer paper 7 that has bypassed the turning roller 4 faces upward.

The torque of the servo motor when it rotates overcomes the torque set by the magnetic powder brake, and pulls the transfer paper to complete the paper collection.

The encoder is connected to the detection wheel, and the detection wheel presses the transfer paper on the transition roller. The encoder signal changes and is fed back to the servo motor to control the transfer paper to move at a constant linear speed.

[0058] The advantages of the present invention are:

[0059] (1) The transfer paper and the ribbon are clamped by the electric heating plates on the upper and lower sides. Both sides of the ribbon are thermally sublimated at the same time to ensure that the position of the transfer paper remains unchanged, thereby improving the position and size of the pattern, logo, mosquito, etc. and improving product quality;

[0060] (2) The double-sided flat pressing method eliminates the use of padding paper and reduces costs;

[0061] (3) During the transfer process, the heating surface is in direct contact with the transfer paper, which improves energy utilization;

[0062] (4) It can transfer multiple ribbons at the same time, thus improving production efficiency.

[0063] In this embodiment, the specific working process is as follows: initially, the webbing is in a state of passing through the hot pressing zone, and the movable clamp is located at the end away from the tape output roller group. The specific steps are as follows:

[0064] (1) The first vertical cylinders 26 of the webbing fixing fixtures 20 at the left and right ends of the hot pressing mechanism 2 drive the lifting seat 24 to move downward, so that the webbing pressing wheel 27 presses the webbing in the transverse through groove 25;

[0065] (2) The electric heating plates 17 located on the upper and lower sides of the hot pressing zone 6 move toward each other under the drive of the lifting cylinder 18. The electric heating plates 17 on the upper and lower sides clamp the transfer paper 7 and the ribbon in the hot pressing zone 6 to complete the double-sided transfer of the ribbon;

[0066] (3) The second vertical cylinder 31 of the movable clamp 21 drives the movable clamp 29 to move downward, and the movable clamp 29 cooperates with the fixed clamp 28 to clamp the webbing. At the same time, the third vertical cylinder 35 of the tape outlet roller group 22 drives the lifting frame 34 to move downward, so that the tape pressing roller 33 cooperates with the tape outlet roller 32 to clamp the webbing;

[0067] (4) The electric heating plates 17 located on the upper and lower sides of the hot pressing zone 6 move in opposite directions under the drive of the lifting cylinder 18, so that the electric heating plates 17 are separated from the transfer paper 7 and the ribbon, and the first vertical cylinder 26 drives the lifting seat 24 to move upward, so that the ribbon pressing wheel 27 no longer presses the ribbon;

[0068] (5) The power mechanism drives the linkage shaft 36 to rotate. When the linkage shaft 36 rotates, it drives the synchronous belt mechanism 37 and the active turntable 38 to rotate synchronously. The driving slider 43 on the synchronous belt mechanism 37 drives the movable clamp 21 to move laterally toward the tape delivery roller group 22. The active turntable 38 drives the driven turntable 39 to rotate together through the connecting rod 40. The tape delivery roller 32 rotates with the driven turntable 39. Under the joint action of the movable clamp 21 and the tape delivery roller 32, the ribbon that has been transferred in the hot pressing zone 6 is pulled out, and the new ribbon is pulled into the hot pressing zone;

[0069] (6) The first vertical cylinders 26 of the webbing fixing fixtures 20 at the left and right ends of the hot pressing mechanism 2 drive the lifting seat 24 to move downward, so that the webbing pressing wheel 27 continues to press the webbing in the transverse through groove 25;

[0070] (7) The third vertical cylinder 35 of the tape outlet roller group 22 drives the lifting frame 34 to move upward, so that the tape pressing roller 33 is separated from the tape outlet roller 32, and the second vertical cylinder 31 of the movable clamp 21 drives the movable clamp plate 29 to move upward, so that the movable clamp plate 29 is separated from the fixed clamp plate 28. Then the power mechanism drives the synchronous belt mechanism 37 and the active turntable 38 to rotate in the opposite direction through the linkage shaft 36, and the synchronous belt mechanism 37 drives the movable clamp 21 to move to the initial position through the driving slider 43;

[0071] (8) Repeat steps (2) to (7).

Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integrated molding using a casting process) (except when it is obviously impossible to use an integrated molding process).
