In a more preferred embodiment, the rotating shaft can adjust the tension of the heat-resistant rolling press felt 402 in the direction toward the heating roller 401, i.e., adjust the pressure of the heat-resistant rolling press felt 402 against the interleaving paper, the textile network core, and the transfer paper. For example, the rotating shaft may be horizontally close to or far from the heating roller 401, or the rotating shaft may be moved along the surface of the heating roller 401 such that the transfer paper, the fibrous texture network core, and the backing paper are constrained by the arc shape of the heat-resistant rolling press felt 402, the transfer paper is pressed against the heating roller 401, the fibrous texture network core is pressed against the transfer paper, and the backing paper is pressed against the fibrous texture network core, thereby achieving better transfer printing. The heat-resistant rolling and pressing felt 402 is made of a high-temperature-resistant needle felt, and is preferably made of high-temperature-resistant fibers such as aramid fibers.
In a preferred embodiment, a temperature measuring point (not shown) is further provided on the heating roller 401. The temperature of the heating roller can be measured at any time by setting the temperature measuring point, so that the constancy of the temperature is ensured, and the transfer printing quality is improved.
(III) interleaving paper
The lining paper is positioned between the fiber texture network sandwich and the heat insulation sleeve 402 and is driven together with the fiber texture network sandwich, so that the dye on the transfer printing paper passes through the meshes of the fiber texture network sandwich and is printed on the lining paper, and the phenomenon that the back of the fiber texture network sandwich is stained with pigment after the heat insulation sleeve 402 is stained with the dye is avoided, and the transfer printing quality is influenced.
The transmission speed of the lining paper and the fiber texture network sandwich is set to be the same, so that the phenomenon that the dye adsorbed on the lining paper is stained on the back surface of the fiber texture network sandwich to influence the transfer printing quality due to relative sliding between the lining paper and the fiber texture network sandwich is avoided.
The lining paper is raw edge paper, the absorption performance of the raw edge paper is good, and the dye can be rapidly absorbed. The paper with the rough edges is divided into a rough surface and a smooth surface, and the rough surface is rough and has stronger absorption performance. The rough nature of the hair side of the lining paper is abutted against the fibrous texture network sandwich, so that the friction force between the lining paper and the fibrous texture network sandwich is increased, and the lining paper and the fibrous texture network sandwich are prevented from sliding relatively.
(IV) tension adjusting device
In a preferred embodiment, the winding and unwinding mechanism for the fibrous texture network sandwich further comprises a tension adjusting device, and the tension adjusting device is disposed downstream of the winding and unwinding roller 201 and upstream of the heating roller 401, and tensions the fibrous texture network sandwich before entering the heating roller 401.
Referring to fig. 1, the tension adjusting apparatus includes:
a first tension roller 205 and a second tension roller 206 arranged in parallel; between the first tension roller 205 and the second tension roller 206, there is a gap through which the fibromuscular network core passes, the fibromuscular network core passing through the gap between the first tension roller 205 and the second tension roller 206, and abutting against the first tension roller 205 and the second tension roller 206.
In a preferred embodiment, the second tension roller 206 is fixedly arranged, the first tension roller 205 is slidable up and down relative to the second tension roller 206, and the sliding direction of the first tension roller 205 is perpendicular to the axial direction thereof. The fibrous texture network sandwich is unwound from the fibrous texture network sandwich unwinding roller 201, and is wound around the heating roller 401 after passing through the gap between the first tensioning roller 205 and the second tensioning roller 206.
Specifically, referring to fig. 3, assuming that the tension of the fibromuscular network sandwich wound from the first tensioning roller 205 to the first tensioning roller 205 is the tension of the first end, when the tension of the first end does not exceed the threshold value, the gravity of the first tensioning roller 205 is greater than the tension of the first end, and the first tensioning roller 205 is in the first position. Referring to fig. 4A, when the tension of the first end exceeds the threshold value, the gravity of the first tension roller 205 is less than the tension of the first end, and the fibrous texture network core pulls the first tension roller 205, so that the first tension roller 205 moves to a direction close to the second tension roller 206, and the first tension roller 205 is in the second position. The second position is higher than the first position.
The first tensioning roller 205 is moved from the first position to the second position, so that the tension on the fibrous texture network sandwich is in a balanced state, and wrinkling can be effectively prevented. At this time, when the tension of the fibromuscular network core is reduced from the gravity greater than that of the first tensioning roller 205, the first tensioning roller 205 again moves from the second position to the first position until the first position where the tension reaches the lowest point.
It is to be understood that the up-and-down sliding described in the present embodiment is defined only for convenience of description according to the illustrated direction, and in practical cases, it may be changed according to the direction in which the tension adjusting means is installed.
In another preferred embodiment, the first tensioning roller 205 and the second tensioning roller 206 are axially rotatable, and the tension adjusting device further comprises a rotation speed adjusting device for controlling the rotation speed of the first tensioning roller 205 and/or the second tensioning roller 206 to increase or decrease the friction between the fibromuscular network core and the two tensioning rollers, thereby adjusting the tension of the fibromuscular network core.
In another preferred embodiment, referring to fig. 4B, the first tensioning roller 205 and the second tensioning roller 206 are fixedly arranged, and the friction between different areas of the surface of the first tensioning roller 205 and/or the second tensioning roller 206 and the fibrous texture network core is different; the tension adjusting means further comprises angle adjusting means for controlling the surface of the first tension roller 205 and/or the second tension roller 206 in contact with the fibromuscular network core, thereby changing the friction between the fibromuscular network core and the two tension rollers.
(V) nip roll
As shown in fig. 7, when the fibrous texture network sandwich is transfer printed on the existing thermal transfer printing equipment, the shrinkage stress in the longitudinal direction and the shrinkage stress in the transverse direction are caused by temperature difference, so that the printing quality is reduced, and the surface is wrinkled or uneven, as shown in fig. 8.
A nip roll is disposed downstream of the heating roll 401 to eliminate shrinkage stress of the fibrous texture network core caused by thermal transfer.
In a preferred embodiment, the flattening roll is a cylindrical straight roll, and spiral grooves (not shown in the figure) are symmetrically distributed on the cylindrical roll surface from the center to two sides. When the fibrous texture network sandwich contacts the roller surface of the flattening roller, friction is generated between the fibrous texture network sandwich and the spiral grooves from the center to the two sides on the roller surface, the spiral grooves expand the fibrous texture network sandwich to the two ends, meanwhile, the friction force between the flattening roller and the fibrous texture network sandwich can be increased, and the flattening effect of the thermally transferred fibrous texture network sandwich in the transverse direction is improved.
In another preferred embodiment, as shown in fig. 5 and 6, the nip roll comprises a mandrel 2021 and a roller 2022 sleeved outside the mandrel 2021; bearing seats 2023 are respectively arranged between the two end parts of the mandrel 2021 and the roller 2022; a plurality of fixed open width strips 2024 which are uniformly distributed along the circumferential direction are fixedly arranged in the middle of the outer wall of the roller 2022, two ends of each fixed open width strip 2024 are respectively provided with a movable open width strip 2025 which can move along the axial direction, and the fixed open width strips 2024 and the movable open width strips 2025 are spliced to form a roller surface.
In a more preferable embodiment, two spiral track grooves 2026 are symmetrically arranged on the mandrel 2021, and the two track grooves 2026 are distributed on two sides of the position where the fixed open width strip 2024 is located; a sliding block 2027 is radially and inwardly arranged on each movable scutching strip 2025 in an extending manner, an axially extending long through hole is arranged on the roller 2022 corresponding to the position of each sliding block 2027, and each sliding block 2027 is inserted into the track groove 2026 in a matching manner by passing through the corresponding long through hole; the two moving open strips 2025 at both ends of each fixed open strip 2024 slide simultaneously toward the fixed open strip 2024 or simultaneously away from the fixed open strip 2024 along the track groove 2026 with the rotation of the roller 2022.
The fiber texture network sandwich after thermal transfer printing drives the flattening roller to rotate under the traction force of the fiber texture network sandwich winding roller 204, the movable open width strip 2025 can do reciprocating outward expansion or inward contraction motion along the axial direction of the mandrel 2021 under the guiding action of the sliding block 2027 embedded into the track groove 2026, and a transverse stress is applied to the fiber texture network sandwich after thermal transfer printing, so that the fiber texture network sandwich is flattened in the transverse direction. The roller 2022 rotates for a circle, a moving open-width strip 2025 on the roller 2022 just moves from a retracted state to an outward-extended state toward the outer end of the roller 2022, then returns to the retracted state, and performs a back-and-forth axial movement, and the slider 2027 thereon slides along one side edge of the track groove 2026 toward the outer end, and then slides along the other side edge of the track groove 2026 toward the inner end.
In another preferred embodiment, each of the moving open strips 2025 is connected to a driving device (not shown in the drawings), which drives the moving open strip 2025 to reciprocate along the surface of the mandrel 2021 in the axial direction of the mandrel 2021.
In the above embodiment, the rotation of the winding roller 204 applies a longitudinal stress to the textile network core after thermal transfer, so as to eliminate the shrinkage deformation in the longitudinal direction caused by thermal transfer.
It should be noted that the above-mentioned transverse stress is proportional to the longitudinal stress. The application time of the longitudinal stress and the transverse stress is more than or equal to the contraction deformation time of the fibrous texture network sandwich caused by thermal transfer printing. The application values of the longitudinal stress and the transverse stress are more than or equal to the shrinkage stress of the fiber texture network sandwich caused by thermal transfer printing.
The winding speed of the fiber texture network sandwich winding roller 204 can be changed by adjusting the rotation speed of the driving motor, so as to form different longitudinal stress and transverse stress. Aiming at the thermal transfer printing of the fiber texture network sandwich with different shrinkage values, the longitudinal stress can be adjusted, the thermal transfer printing is carried out, the deformation is observed, and the shrinkage deformation of the fiber texture network sandwich caused by the thermal transfer printing is conveniently eliminated.
It should be understood that in the above two embodiments, the number of the nip rolls may be set to one or more. As shown in fig. 1, for example, two nip rolls are provided, including a first nip roll 202 and a second nip roll 203, which are parallel to each other in the axial direction, the first nip roll 202 being disposed downstream of the heating roll 401, and the second nip roll 203 being disposed downstream of the first nip roll 202 and upstream of the fibrous texture web core-winding roll 204. The number of the flattening rollers is set according to the actual flattening effect after the fiber texture network sandwich is transferred.
FIG. 9 is a schematic diagram of the effect of the fibrous texture network sandwich after thermal transfer without the nip roll. As shown in fig. 9, since the fiber texture network core after thermal transfer printing can only eliminate shrinkage stress in one direction by stretching in one direction without using a flattening roll, the surface still has wrinkles or unevenness. Referring to fig. 7, because some connection points exist between fibers of the fibrous texture network sandwich, the fibers are heated and deformed in the thermal transfer process, and the surrounding fibers are driven to deform together under the action of the connection points, so that the problems of unevenness such as wrinkles, bulges and the like are formed (refer to fig. 8). The general textile fiber cloth does not have connecting points, the fibers are only contacted with each other, and the problem of unevenness can be solved after unidirectional stretching. FIG. 10 is a schematic diagram illustrating the effect of the fibrous texture network sandwich after thermal transfer printing of the present application after the transverse shrinkage stress and the longitudinal shrinkage stress are eliminated. As shown in fig. 10, in the case of applying a bidirectional tensile force, the fiber texture network sandwich after thermal transfer printing simultaneously eliminates the transverse shrinkage stress and the longitudinal shrinkage stress, and the surface of the fiber texture network sandwich is flat, and the phenomenon of wrinkles or unevenness completely disappears.
To sum up, the utility model provides a pair of fiber texture network presss from both sides heat-transfer seal system of core sets up the nip roll through the low reaches at the warming mill, has eliminated the shrinkage stress of the fiber texture network that arouses by the heat-transfer seal and presss from both sides the core, makes fiber texture network press from both sides the core level and smooth, reduces the shrink, avoids appearing the condition of surface fold or unevenness, makes the fiber texture network that the heat-transfer seal was pressed from both sides the core pattern homogeneity good, and is more pleasing to the eye, and the quality is higher.
