[0033] like Figures 1 to 9 As shown together, this embodiment provides a double-sided movable drying mechanism for a digital printing machine, which includes an L-shaped frame 1, a placement plate 2 is provided inside the L-shaped frame 1, a drying assembly 3 is provided on one side of the placement plate 2, and two groups of drying assemblies 3 are provided, which correspond to each other. Positioning assemblies 9 are installed at the four corners of the placement plate 2; The drying assembly 3 includes a drying box 31 located inside the L-shaped frame 1. A control panel 32 is provided on one side of the drying box 31. A mounting frame 33 is fixedly installed inside the drying box 31. Heating wires 34 are installed inside the mounting frame 33. The heating wires 34 are arranged at equal intervals. The control panel 32 is used to control the opening and closing of the heating wires 34 and adjust the temperature of the heating wires 34. A folding window 35 is installed on one side of the drying box 31. There are two groups of folding windows 35 that correspond to each other. A drying plate 36 is installed between the two groups of folding windows 35. A fan 37 is installed on the surface of the drying plate 36. The fans 37 are arranged at equal intervals. The interior of the drying plate 36 is provided with through holes 38 arranged at equal intervals. The fans 37 are connected to the drying plate 36 by bolts, which can be easily replaced or maintained. The fan 37 is used to output the heat of the heating wire 34 to facilitate the drying operation of the fabric. At the same time, by arranging folding windows 35 on both sides of the drying plate 36, the drying plate 36 can be moved, thereby adjusting the wind distribution of the fan 37. The cloth position can be adjusted according to the distribution of the cloth and the drying requirements, so that the air flow can be optimized according to the distribution of the cloth and the drying requirements, ensuring that the hot air can evenly penetrate every part of the cloth. In addition, the fan 37 can evenly transfer the heat inside the drying component 3 to the cloth surface, ensuring that the hot air can quickly and evenly cover the entire cloth, thereby improving the drying efficiency. The slidable fan 37 can adjust its position as needed to optimize the heat distribution in different areas, avoiding local uneven drying or drying dead corners caused by the fixed position of the fan 37. At the same time, the setting of the through hole 38 can facilitate air circulation, thereby increasing the uniformity of fabric drying.

[0034] A ceramic fiber layer 391 is installed on the top of the mounting frame 33, and a glass wool layer 39 is installed on the top of the ceramic fiber layer 391. A dehumidification hole 392 is opened on the top of the drying box 31, and the dehumidification holes 392 are arranged at equal intervals. The ceramic fiber layer 391 and the glass wool layer 39 can reduce the loss of heat inside the drying box 31. Moisture will be generated during the drying process, and due to the corresponding setting of the drying box 31, moisture may enter the drying box 31. The moisture can be discharged through the dehumidification holes 392, thereby preventing the humidity in the air or the drying box 31 from being too high, affecting the drying efficiency, avoiding moisture accumulation in the drying environment, and allowing the air to continue to remain in a dry state, thereby improving the overall drying speed and effect.

[0035] Both ends of the drying plate 36 are fixedly connected with guide blocks 361, and the inner sides of the two groups of folding windows 35 are provided with guide grooves 362 adapted to the guide blocks 361. The guide blocks 361 and the folding windows 35 are connected by bolts 363. A driving part 4 is installed on one side of the drying box 31. The guide blocks 361, guide grooves 362 and bolts 363 can make the connection between the drying plate 36 and the folding windows 35 more stable, avoiding the phenomenon of offset during movement. The bolts 363 are bolt structures, and at the same time, combined with the setting of the folding windows 35, it is convenient for internal inspection of the drying box 31, thereby reducing the overall steps of disassembling the drying box 31.

[0036] The driving member 4 includes a motor 41 fixed to one side of the drying box 31. The output end of the motor 41 is fixedly connected to a screw 42. The outer surface of the screw 42 is threadedly connected to a slider 43. The other end of the screw 42 is rotatably connected to the drying box 31. A chute 44 is provided on one side of the drying box 31. The chute 44 is located on one side of the screw 42. One end of the slider 43 extends through the chute 44 to the interior of the drying box 31 and is fixedly connected to the drying plate 36, so as to drive the drying plate 36 to move. The direction and concentration area of ​​air flow can be controlled, and the position of the fan 37 can be adjusted according to the moisture distribution of the fabric to ensure that moisture is quickly discharged and improve the drying effect.

[0037] The two drying boxes 31 are fixedly connected to a connecting rod 5 on the side away from each other. The connecting rod 5 is C-shaped and equidistantly arranged. The other end of the connecting rod 5 is fixedly connected to a T-block 6. The two drying components 3 are connected to the T-block 6 via the connecting rod 5. A T-shaped slot 7 is provided inside the L-shaped frame 1 to match the T-shaped block 6. A first electric push rod 8 is fixedly installed at one end of the L-shaped frame 1. The output end of the first electric push rod 8 extends to the inside of the L-shaped frame 1 and is fixedly connected to the T-shaped block 6, which can facilitate the adjustment of the position of the drying component 3, thereby improving the flexibility of the drying component 3. At the same time, the movable drying component 3 can reduce the steps of removing the fabric from the printing placement plate 2, thereby saving work steps and avoiding the phenomenon of inaccurate drying position caused by moving the fabric.

[0038] The positioning assembly 9 includes a conical shell 91 located on the placement plate 2. A positioning shell 96 is fixedly connected to the interior of the conical shell 91. A sliding shell 94 is movably connected to the interior of the positioning shell 96. The bottoms of the positioning shell 96 and the sliding shell 94 are both conical in shape. The bottom of the sliding shell 94 is movably connected to positioning steel balls 95. The positioning steel balls 95 are arranged in a ring array. The interior of the sliding shell 94 is provided with grooves adapted to the positioning steel balls 95. A tension spring 92 is fixedly connected to the inside of the conical shell 91, and a conical block 93 is fixedly connected to the bottom of the tension spring 92. The conical block 93 is located inside the sliding shell 94 and is movably connected to it. It can position the positioning steel needle 99 to achieve the purpose of fixing the fabric.

[0039] Slide bars 97 are fixedly connected to both sides of the sliding shell 94, and a limiting groove 98 adapted to the slide bars 97 is opened on the inner side of the positioning shell 96 to facilitate the lifting and lowering operation of the sliding shell 94 and prevent the sliding shell 94 from deflecting.

[0040] A positioning steel needle 99 is provided at the bottom of the placement plate 2, and the outer surface of the positioning steel needle 99 is provided with equally spaced card slots 991. One end of the positioning steel needle 99 passes through the placement plate 2 and extends to the interior of the positioning shell 96, and is located between multiple groups of positioning steel balls 95. The card slot 991 is located between multiple groups of positioning steel balls 95, which can facilitate the positioning operation of the positioning steel needle 99. Through the setting of the card slot 991, the positioning of the positioning steel needle 99 can be made more stably, and the fabric can be more stably installed on the placement plate 2, thereby avoiding wrinkles or offsets in the fabric.

[0041] A second electric push rod 10 is fixedly installed inside the L-shaped frame 1, and the output end of the second electric push rod 10 is fixedly connected to a connecting rod 11. The other end of the connecting rod 11 is fixedly connected to the placement plate 2, which can facilitate the adjustment of the forward and backward movement of the placement plate 2, thereby increasing the drying range of the fabric. At the same time, the placement plate 2 is located at a height between the two groups of drying components 3, which can facilitate the drying operation of the fabric by the drying components 3. At the same time, a cavity is opened inside the placement plate 2 to facilitate the insertion of the positioning steel needle 99.

[0042] When in use, the fabric to be dried is spread flat on the placement plate 2, and the conical shells 91 are placed at the four corners of the placement plate 2 respectively, and then the positioning steel needle 99 is inserted from the bottom of the placement plate 2 and penetrates the fabric and the positioning shell 96. When the positioning steel needle 99 is inserted into the positioning shell 96, the top of the positioning steel needle 99 will push the sliding shell 94 and the tension spring 92 upward, and make the sliding shell 94 rise along the inside of the limiting groove 98 through the slide bar 97, so that the tension spring 92 is squeezed and deformed. In this process, the positioning steel balls 95 will rise with the rise of the sliding shell 94 until the card groove 991 on the outer surface of the positioning steel needle 99 is located in the multiple groups of positioning steel balls 95, and then the pressure on the positioning steel needle 99 is cancelled, and the tension spring 92 recovers its deformation and pushes the sliding shell 94 and the positioning steel balls 9 5 descends, and since the bottom of the sliding shell 94 is conical, it can be used to position the positioning steel ball 95, that is, the positioning steel ball 95 cannot move, and at the same time the positioning steel ball 95 can clamp the positioning steel needle 99, so that the purpose of fixing the fabric can be achieved. When the positioning steel needle 99 needs to be removed, a permanent magnet is placed on the top of the conical shell 91 to drive the positioning steel ball 95 to rise by magnetic force, and the tension spring 92 is squeezed to produce deformation. The positioning steel ball 95 will cancel the lock with the positioning steel needle 99 during the rising process, so that it can be removed. In this way, the fabric can be stably fixed on the placement plate 2, preventing the fabric from being deformed or twisted due to the action of hot air or air flow during the drying process, thereby maintaining the original shape of the fabric and avoiding wrinkles or uneven drying effects.

[0043] The fabric is fixed on the placement plate 2 by the above placement, and then printed by the printing device. After the printing is completed, the first electric push rod 8 is started to push the T-block 6 to drive the two sets of drying components 3 to move toward the placement plate 2 until the two sets of drying components 3 cover the placement plate 2, thereby achieving the purpose of double-sided drying; The heating wire 34 is started through the control panel 32, and then the heat generated by the heating wire 34 is transferred to the fabric through the fan 37. At the same time, the motor 41 can be started to drive the screw 42 to rotate according to the specifications of the fabric, and the slider 43 can be used to drive the drying plate 36 along the inside of the slide 44 for operation adjustment. During this process, the movement of the drying plate 36 can enable the two sets of folding windows 35 to fold and stretch to avoid the risk of heat leakage. At the same time, since the drying plate 36 is connected to the fan 37 and the folding window 35 by bolts, it is convenient to inspect the interior of the drying box 31, and the folding window 35 can be directly pulled to facilitate the inspection of the drying component 3.

[0044] At the same time, the second electric push rod 10 can be started to drive the placement plate 2 to move forward and backward, so as to increase the drying range of the fabric, thereby making the fabric drying more uniform and comprehensive.
