Description

Technical Field

[0001] This utility model relates to the technical field of drying equipment for digital inkjet printing cloth, specifically a non-contact drying oven for digital inkjet printing cloth. Background Technology

[0002] In the field of digital inkjet printing, the drying process after fabric printing is crucial to the adhesion of the pattern and the quality of the fabric. Existing drying equipment has some shortcomings in design and function, which limits its application in efficient production and high-quality drying.

[0003] Traditional drying equipment involves direct contact between the fabric and the drying components, which can easily damage the fabric surface, affecting the integrity of the pattern and the texture of the fabric. Existing drying equipment also presents inconveniences in fabric conveying and unloading. For example, the introduction and removal of fabric during the drying process are not smooth enough, easily leading to jamming or wrinkles. Furthermore, the speed of introduction and removal cannot be adjusted to allow the fabric to be dried vertically without contact within the drying chamber.

[0004] Furthermore, traditional drying equipment has a relatively simple drying channel design, allowing fabric to pass through in only one direction, which cannot achieve uniform drying on both sides and affects the bonding effect between the pattern and the fabric. Extensive research has been conducted on this issue. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a device that can achieve non-contact vertical drying of fabrics, efficient material feeding, and uniform drying, so as to improve the drying quality and production efficiency of digital inkjet printed fabrics.

[0010] A further technical solution is that the lifting mechanism includes a cylinder fixedly mounted on the drying box, a retainer provided on the push rod of the cylinder, and both ends of the pressing roller being movably mounted in the inner groove of the retainer.

[0011] In a further technical solution, the feeding device includes a feeding roller, which is detachably connected to the drying box, and the drying box is provided with a second power mechanism that drives the feeding roller to rotate.

[0012] A further technical solution includes a second power mechanism comprising a fixed plate fixedly disposed on one side of the drying chamber, a second reducer motor fixedly disposed on the fixed plate, a drive gear fixedly disposed on the output shaft of the second reducer motor, and a driven gear fixedly disposed on the outer surface of the feeding roller. When the feeding roller is installed inside the fixed plate, the driven gear meshes with the drive gear.

[0013] A further technical solution is provided where the two ends of the feeding roller are fitted with mating bearings, and a mounting seat is fixedly provided on one side of the fixing plate. The mounting seat has a groove, and the mating bearing is engaged in the groove. A threaded rod is provided in the mounting seat, and the threaded rod limits and fixes the mating bearing in the groove. The threaded rod passes through one end of the mounting seat and extends into the groove, where it is threadedly engaged with the threaded hole in the groove.

[0014] In a further technical solution, the drying device includes multiple electric heating rods fixedly installed inside the drying chamber, and the electric heating rods are arranged in a vertical array.

[0015] In a further technical solution, multiple supports are fixedly installed at the bottom of the inner side of the drying box, and bottom rollers are rotatably installed at both ends of the supports.

Detailed Implementation

[0034] like Figures 1-11 As shown, this utility model will be described in detail. For ease of description, the directions mentioned below are defined as follows: the directions of up, down, left, right, front, and back mentioned below are the same as... Figure 1 The projection relationship is consistent in the up, down, left, right, front, and back directions. This utility model discloses a non-contact drying oven for digital inkjet printing cloth, including a drying box 11. The top of the drying box 11 is provided with two openings 12. A conveying device 92 for conveying cloth is provided on one side of the opening 12. A detachable feeding device 91 is provided on one side of the drying box 11. The feeding device 91 is used to wrap the dried cloth. A drying device 93 is provided inside the drying box 11. A drying channel is provided in the drying device 93. The cloth is released from the feeding device 91 and introduced into one of the openings 12 under the transportation of the conveying device 92. After passing through the drying channel, it is hung up without contact in the drying box 11 and then led out from the other opening 12.

[0035] Advantageously, the top of the drying oven 11 is provided with an exhaust pipe 31, which is used for exhausting air.

[0036] Advantageously, the conveying device 92 includes two synchronously operating second rollers 29 and first rollers 28. The second rollers 29 are disposed on one side of the opening 12. The first rollers 28 are provided with a pressing roller 27 that moves up and down. The first rollers 28 and the second rollers 29 are driven to rotate by a first power mechanism. The pressing roller 27 is lifted by a lifting mechanism. The pressing roller 27 presses the fabric down onto the upper end face of the first roller 28, and then passes through the outer surface of the second rollers 29, so that the fabric can enter and exit the opening 12, realizing the movement process of the fabric.

[0037] Advantageously, the first power mechanism includes a first reducer motor 22 disposed on the top of the drying chamber 11, the first reducer motor 22 being poweredly connected to the first roller 28, the first roller 28 being rotatably connected to the top of the drying chamber 11, and a gear transmission assembly being disposed between the first roller 28 and the second roller 29 to make the second roller 29 and the first roller 28 rotate in the same direction.

[0038] Advantageously, the gear transmission assembly includes a third gear 34 fixedly disposed on one side of the second roller 29, a first gear 32 fixedly disposed on one side of the first roller 28, and a second gear 33 meshing between the third gear 34 and the first gear 32. The second gear 33 is rotatably connected to the top of the drying chamber 11. Through the meshing of the second gear 33 with the third gear 34 and the first gear 32, the third gear 34 and the first gear 32 drive the second roller 29 and the first roller 28 to rotate in the same direction.

[0039] Advantageously, the lifting mechanism includes a cylinder 23 fixedly mounted on the drying chamber 11. The push rod of the cylinder 23 is provided with a retainer 24. The two ends of the pressing roller 27 are movably mounted in the inner groove of the retainer 24. Bearings are also provided at both ends of the pressing roller 27. The top of the drying chamber 11 is provided with a U-shaped groove to accommodate the bearings. When the pressing roller 27 is in the lower position, the bearings are placed in the U-shaped groove. At this time, the pressing roller 27 presses the fabric tightly against the outer surface of the first roller 28 to avoid the weight of the pressing roller 27 being concentrated on the cylinder 23.

[0040] Advantageously, the feeding device 91 includes a feeding roller 13, which is detachably connected to the drying box 11, and the drying box 11 is provided with a second power mechanism that drives the feeding roller 13 to rotate.

[0041] Advantageously, the second power mechanism includes a fixed plate 16 fixedly disposed on one side of the drying box 11, a second reducer motor 17 fixedly disposed on the fixed plate 16, a drive gear 18 fixedly disposed on the output shaft of the second reducer motor 17, and a driven gear 14 fixedly disposed on the outer surface of the feeding roller 13. When the feeding roller 13 is installed in the fixed plate 16, the driven gear 14 meshes with the drive gear 18.

[0042] Advantageously, the feeding roller 13 is fitted with mating bearings 42 at both ends, and a mounting base 15 is fixedly provided on one side of the fixing plate 16. The mounting base 15 is provided with a groove 43, and the mating bearing 42 is snapped into the groove 43. A threaded rod 41 is provided in the mounting base 15. The threaded rod 41 limits and fixes the mating bearing 42 in the groove 43. The threaded rod 41 passes through one end of the mounting base 15 and extends into the groove 43, where it is threadedly connected to the threaded hole in the groove 43. The threaded rod 41 passes through the threaded hole and protrudes from one side of the mounting base 15.

[0043] Advantageously, the drying device 93 includes a plurality of electric heating rods 51 fixedly installed inside the drying chamber 11. The electric heating rods 51 are arranged in a vertical array, and there are three sets of electric heating rods 51.

[0044] Advantageously, a side plate 52 is fixedly installed inside the drying oven 11. The side plate 52 is located on one side of the electric heating rod 51. The side plate 52 is used to separate the electric heating rod 51, and multiple heat dissipation holes are provided inside the side plate 52.

[0045] Advantageously, multiple supports 54 are fixedly installed on the bottom inner side of the drying box 11, and bottom rollers 53 are rotatably installed at both ends of the supports 54. The bottom rollers 53 are used to prevent the fabric from entering between the side plates 52 when it moves upward, thus playing a protective role.

[0046] Advantageously, the bottom of the opening 12 is provided with guide openings 61 and 63 for the fabric to pass through. In the specific arrangement, the fabric on the outer surface of the second roller 29 passes through the opening 12 and the guide opening 61 and then extends into the drying box 11 and hangs down.

[0047] Fabric ejected from the digital inkjet printer is rolled onto the unloading device 91, then passes through one of the conveying devices 92 and enters the drying chamber 11 through an opening 12 on one side. After passing through the drying device 93, the fabric is bent inside the drying chamber 11 and pulled out through another opening 12. It is then squeezed and conveyed again by the conveying device 92 on one side of the unloading device 91 and piled on the ground for easy handling. The fabric does not come into contact with the drying devices 93 or the inner end wall of the drying chamber 11 while moving between the drying devices 93, thus achieving a non-contact drying function.

[0048] When the conveying device 92 is working, the fabric passes over the upper surface of the first roller 28, and after the cylinder 23 is working, it drives the card seat 24 and the pressing roller 27 to move downward, so that the pressing roller 27 presses the fabric. After the first reducer motor 22 is working, it drives the first roller 28 to rotate. Through the transmission of the first gear 32, the second gear 33 and the third gear 34, the second roller 29 also rotates synchronously with the first roller 28.

[0049] The fabric is wound around the outer surface of the feeding roller 13. After the second reducer motor 17 is working, it drives the drive gear 18 to rotate, which in turn drives the driven gear 14 and the feeding roller 13 to rotate. This releases the fabric from the outer surface of the feeding roller 13. After being squeezed and conveyed by the first roller 28, the fabric enters the opening 12 from the upper end of the second roller 29. The drying device 93 consists of two drying channels composed of three sets of electric heating rods 51. After passing through the second roller 29, the fabric is introduced into the first drying channel. After being turned around at the bottom of the drying box 11, it is led out of the opening 12 from the second drying channel and abuts against the upper end of another second roller 29. Then, it passes through the upper end of the first roller 28 in another conveying device 92 and continues to be conveyed. The fabric is then piled on the ground for easy handling.

[0050] like Figure 1 As shown, the fabric is introduced through the left opening, hangs in a U-shaped path inside the drying chamber, passes through two sets of drying channels, and is then led out from the right opening.

[0051] After the fabric is completely released from the outer surface of the feed roller 13, the threaded rod 41 is rotated to disengage the threaded connection between the threaded rod 41 and the threaded hole on the inner wall of the groove 43, so that the threaded rod 41 can be pulled out from the groove 43. At this time, the bearing 42 is not limited by the threaded rod 41, and personnel can remove the feed roller 13 with the fabric wrapped around it by forklift or manual labor.

[0052] For the fabric, the operating speed of the conveyor 92 on the feeding side represents the feeding speed of the fabric, and the operating speed of the conveyor 92 on the discharging side represents the discharging speed of the fabric. After the fabric enters the drying chamber 11, both ends of the fabric are pressed and connected to the conveyor 92 to realize the displacement conveying function. When adjusting the fabric, it can be made to hang the fabric in the drying chamber 11. That is, if the fabric is close to the bottom roller 53 in the drying chamber 11, the length of the fabric in the drying chamber 11 will gradually increase by making the operating speed of the conveyor 92 on the feeding side greater than the operating speed of the conveyor 92 on the discharging side. Then, due to gravity, the bottom of the fabric will separate from the bottom roller 53.

[0053] Similarly, when the fabric is close to the bottom of the inner side of the drying chamber 11, the fabric inside the drying chamber 11 will gradually become shorter and the bottom of the fabric will gradually move upward by increasing the speed of the discharge side conveyor 92 to be greater than the speed of the feed side conveyor 92.

[0054] When the bottom of the fabric is adjusted so that it does not contact the bottom roller 53 and the bottom end wall of the drying chamber 11, the fabric can be hung vertically in the drying channel between the electric heating rods 51 under the guidance of the second roller 29. When adjusted to the correct position, the fabric will not contact the electric heating rods 51 and the side plate 52.

[0055] When the fabric is in the correct position, the conveyor devices 92 on both sides operate at the same speed to keep the fabric in a non-contact state.

[0056] When the fabric is initially pulled into the equipment, it needs to be guided manually. If necessary, the equipment's baffle can be removed to allow personnel to pull the fabric. The equipment is not in operation when pulling the fabric.

[0057] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without creative effort should be included within the protection scope of this utility model; therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
