Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of mechanical equipment field for printing, more particularly to a kind of printing equipment with oven. BACKGROUND

[0002] At present, printing is carried out on paper, cloth and other thin carriers by printing equipment to form various beautiful patterns or pictures, and the printing method includes spraying and printing. In spraying, ink is sprayed on the thin carrier according to a preset track.

[0003] In order to prevent the mark on the thin carrier from being damaged by touching other objects before the ink is dried, a drying process is usually added after the spraying is completed. The commonly used drying device is an oven. The existing oven can dry the ink on the thin carrier to a certain extent. However, the existing oven has many defects.

[0004] Firstly, the oven is arranged on the spraying equipment, which inevitably leads to a large size of the spraying equipment. Especially when the thin carrier passes through the oven, it needs to be collected and released by the collecting and releasing rollers. As shown in FIG. Figure 1 In order to ensure that the side of the thin carrier on which the ink is sprayed does not contact the oven when passing through the oven, the collecting and releasing rollers are arranged before and after the oven. Therefore, a plurality of collecting and releasing rollers need to be arranged on the spraying equipment.

[0005] Secondly, when drying the thin carrier, the existing oven usually directs the hot air formed by the heating pipe to the side of the thin carrier on which the ink is sprayed by a fan. During the drying process, the thin carrier shrinks due to heat, which causes wrinkles on the thin carrier. As a result, the picture on the thin carrier is dislocated due to the wrinkles, which affects the quality of the final picture.

[0006] In addition, when drying the thin carrier, the wind pressure received by the thin carrier in the extension direction is extremely uneven, which causes severe shaking of the thin carrier.

[0007] More importantly, a plurality of fans are arranged in some ovens. When the fans blow air, the thin carrier between the two fans shakes violently. As a result, the ink on the thin carrier is severely dislocated, which affects the quality and the pass rate of the final product. SUMMARY

[0051] Reference Figures 2 to 12B A printing equipment with an oven according to a preferred embodiment of the present application will be described in detail below, wherein the printing equipment with an oven comprises at least one oven 100, a printing assembly 300, at least one set of transmission rollers 500 and an equipment main body 700.

[0052] A set of the transmission rollers 300 are coaxially arranged on the equipment main body 700, and a set of the transmission rollers 300 are arranged on the path of the thin carrier 900 that needs to be driven. Specifically, the transmission rollers 500 comprise an unwinding roller 510, at least one conveying roller 520 and a winding roller 530. The unwinding roller 510, the conveying roller 520 and the winding roller 530 are all rotatably mounted on the equipment main body 700, and the unwinding roller 510 is arranged to unwind the thin carrier 900, wherein the conveying roller 520 is used to change the conveying direction of the thin carrier 900, and wherein the winding roller 530 is used to wind the thin carrier 900 after being printed and dried.

[0053] The printing assembly 700 is arranged on the transmission path of the thin carrier 900 to print at least one side of the thin carrier 900. The printed thin carrier 900 is conveyed to the oven 100 for drying through the conveying roller 520. Finally, the thin carrier 900 is wound by the winding roller 520.

[0054] In a preferred embodiment, the oven can be used to dry the thin carrier 900, and hot air can be used cyclically. Those skilled in the art can understand that the thin carrier 900 can be paper, canvas, etc., and the present application is not limited in this regard.

[0055] Specifically, the oven comprises a housing 10, wherein the housing 10 has an inlet end 101 and an outlet end 102, wherein the thin carrier 900 is capable of moving from the inlet end 101 towards the outlet end 102.

[0056] The housing 10 forms a mounting cavity 103 between the inlet end 101 and the outlet end 102, and the housing 10 further forms a set of air outlets 104 in communication with the mounting cavity 103 on top of the mounting cavity 103 between the inlet end 101 and the outlet end 102.

[0057] Preferably, the air outlets 104 are oriented obliquely towards the outlet end 102 to avoid the air directed from the air outlets 104 blowing vertically against the thin carrier 900 and causing the thin carrier 900 to be subjected to excessive pressure.

[0058] Preferably, a transverse direction is defined from the inlet end 101 to the outlet end 102, wherein each of the air outlets 104 is arranged to extend along a longitudinal direction perpendicular to the transverse direction, such that the oven is capable of forming hot air to cover the entire longitudinal width of the thin carrier 900. That is, the air outlets 104 are elongated openings extending along the longitudinal direction.

[0059] Also preferably, the housing 10 forms a plurality of the air outlets 104, wherein the plurality of the air outlets 104 are arranged along the transverse direction at intervals to increase the area of the oven capable of drying the thin carrier 900. More preferably, the plurality of the air outlets 104 are arranged along the transverse direction at equal intervals.

[0060] Specifically, the housing 10 has a housing body 11 and an air outlet plate 12, wherein the top of the housing body 11 forms the mounting cavity 103 at a corresponding position, and wherein the air outlet plate 12 covers the top of the mounting cavity 103 and forms the air outlets 104.

[0061] The oven comprises at least one set of heat generators 20 and at least one air blower 30. The air blower 30 is arranged in the mounting cavity 103 of the housing 10 near the inlet end 101. The heat generators 20 are also arranged in the mounting cavity 103 and located on the flow path of the flowing air formed by the air blower 30.

[0062] The fan 30 is arranged to direct air from the feeding end 101 to the discharging end 102. During the process of air being directed from the feeding end 101 to the discharging end 102 by the fan 30, the air is heated by the heat generator 20, and the hot air can be directed out through the air outlet 104. The hot air formed after being heated by the heat generator 20 can flow out from the air outlet 104, and dry the ink on the thin carrier 900 opposite to the air outlet 104. Preferably, the fan 30 is arranged close to the feeding end 101.

[0063] As a preferred embodiment, the oven comprises a plurality of heat generators 20, wherein the plurality of heat generators 20 are arranged at intervals along the transverse direction, preferably at equal intervals. In this way, the thin carrier 900 opposite to the air outlet 104 can be dried uniformly.

[0064] It is worth mentioning that, on the oven body 10, preferably on at least one side of the two sides in the longitudinal direction of the mounting cavity 103, at least one return air passage 105 separated from the mounting cavity 103 and a group of return air holes 106 communicating with the return air passage 105 are formed. The return air holes 106 are arranged at the top of the return air passage 105, and a group of return air holes 106 are arranged at intervals along the transverse direction. At the same time, the return air passage 105 is communicated with the air inlet of the fan 30 close to the feeding end 101.

[0065] As a preferred embodiment, on the oven body 10, at least one return air passage 105 separated from the mounting cavity 103 and a group of return air holes 106 communicating with the return air passage 105 are formed on each of the two sides in the longitudinal direction of the mounting cavity 103. In this way, after the hot air is directed out from the air outlet 104, the used hot air can flow back to the return air passage 105 from the return air holes 106 on both sides of the thin carrier 900 under the action of negative pressure of the fan 30 at the feeding end 101, and constantly flow to the air inlet of the fan 30, because the fan 30 close to the feeding end 101 is working.

[0066] In this way, the hot air can be effectively recycled and utilized.

[0067] As preferred, the box 10 further comprises at least one partition 13, wherein the partition 13 is arranged in the installation cavity 103 to divide the installation cavity 103 into a first installation cavity 1031 and a second installation cavity 1032, and a communication passage 108 is formed between the partition 13 and the air outlet plate 12 to enable the first installation cavity 1031 and the second installation cavity 1032 to communicate through the communication passage 108.

[0068] The fan 30 is installed in the first installation cavity 1031. In a preferred embodiment, a plurality of the heat generators 20 are arranged in the second installation cavity 1032 at intervals. Preferably, the communication passage 108 is arranged on both sides of the longitudinal direction, so that the hot air flowing back from the air return hole 106 can be more guided by the fan 30 to the second installation cavity 1032 through the communication passage 108.

[0069] As understood by those skilled in the art, through such an arrangement, the oven can achieve the recycling of hot air without arranging two fans blowing air in opposite directions.

[0070] Further preferably, the box 10 further comprises an air return plate 14, wherein the air return plate 14 is arranged at the discharge end 102, and the air return plate 14 is arranged to extend upwardly and tilt towards the feeding end 101. At the same time, the box 10, i.e. the air outlet plate 12, forms an air return hole 109 between the air return plate 14 and the feeding end 101, and close to the air return plate 14.

[0071] As preferred, the air return hole 109 and the air return plate 14 are arranged to extend along the longitudinal direction. In this way, when the hot air is guided by the fan 30 from the air outlet hole 104 to flow to the discharge end 102, a part of the hot air will flow back to the installation cavity 103 from the air return hole 109 due to the blocking of the air return plate 14. In a preferred embodiment, the air return passage 105 communicates with the installation cavity 103 close to the discharge end 102, and the air return hole 109 communicates with the air return passage 105. In this way, the hot air flowing back from the air return hole 109 can also flow to the air inlet of the fan 30 through the air return passage 105.

[0072] As a preferred, in one embodiment, the hole diameter of the return air hole 106 gradually decreases from the discharge end 102 to the feeding end 101. In this way, when the fan 30 is working, the hot air from the air outlet 104 near the fan 30 can be reduced to be excessively returned from the return air hole 106. In this way, not only can the thin carrier 900 near the fan 30 be dried by sufficient hot air, but also the hot air can be circulated back.

[0073] In another embodiment, the spacing between two adjacent return air holes 106 gradually decreases from the discharge end 102 to the feeding end 101. In this way, when the fan 30 is working, the return air hole 106 near the fan 30 can be reduced to be disturbed.

[0074] Further preferably, the box 10 further comprises a cover plate 15, wherein the two sides of the cover plate 15 are mounted on the two longitudinal sides of the box 10 and form a material body passage 109 with the air outlet plate 12 to pass the thin carrier 900.

[0075] The cover plate 15 is covered on the air outlet 104 formed by the box 10, so as to avoid the loss of hot air. Those skilled in the art can understand that, since the cover plate 15 and the return air plate 14 are respectively arranged around the air outlet 104, at the same time, the fan 30 continuously guides the hot air to flow from the feeding end 101 to the discharge end 102, and then returns through the return air hole 106. In this way, the hot air can be fully utilized to dry the thin carrier 900.

[0076] More preferably, one side of the cover plate 15 towards the air outlet 104 forms an arc surface 1501 to abut the side of the thin carrier 900 on which the ink is sprayed. In addition, the arc surface 1501 is provided with an anti-wrinkle structure 40.

[0077] In one embodiment, the arc surface 1501 formed by the cover plate 15 is located between the conveying roller 520 and the winding roller 530. In this way, the arc surface 1501 formed by the cover plate 15 can tighten the thin carrier 900. In this way, at least one conveying roller 520 between the cover plate 15 and the winding roller 530 can be omitted. In this way, the volume of the entire inkjet printing equipment with the oven will be reduced. As shown in FIG. 12.

[0078] In one embodiment, the anti-wrinkle structure 40 comprises at least one pair of ribs 41, wherein the pair of ribs 41 are symmetrically arranged along the transverse direction on the arc surface 1501, and the distance between the two ribs 41 of the pair of ribs 41 near the end portion of the feed end 101 is smaller than the distance between the two ribs 41 of the pair of ribs 41 near the end portion of the discharge end 102.

[0079] By such an arrangement, while the thin carrier 900 is dried by the oven, the anti-wrinkle structure 40 can give the thin carrier 900 a force to expand along the longitudinal direction, because the thin carrier 900 is pressed against the anti-wrinkle structure 40. As is known, the thin carrier 900, especially paper or film, tends to shrink inwardly when being dried. By arranging the anti-wrinkle structure 40, the degree of the thin carrier 900 shrinking inwardly when being dried can be effectively reduced, because the anti-wrinkle structure 40 gives the thin carrier 900 a force to expand outwardly when being dried.

[0080] Preferably, the anti-wrinkle structure 40 comprises a plurality of pairs of ribs 41. Preferably, one rib 41 of each pair of the plurality of pairs of ribs 41 is arranged along the longitudinal direction on one side of the arc surface 1501 along the longitudinal direction, and the other rib 41 of each pair of the plurality of pairs of ribs 41 is arranged along the longitudinal direction on the other side of the arc surface 1501 along the longitudinal direction. In this way, the distance between the two ribs 41 of the pair of ribs 41 near the side of the arc surface 1501 along the longitudinal direction is larger.

[0081] More preferably, a plurality of pairs of anti-wrinkle structures 40 are arranged along the transverse direction.

[0082] As can be understood by those skilled in the art, by such an arrangement, the degree of deformation of the thin carrier 900 due to drying can be effectively reduced.

[0083] It is worth mentioning that the cross-sectional dimension of the installation cavity 103 in the vertical direction gradually decreases from the position where the fan 30 is installed to the discharge end 103 along the direction from the feed end 101 to the discharge end 103. Those skilled in the art can understand that, since the amount of gas in the installation cavity 103 of the fan is more close to the position where the fan 30 is installed and less far away from the position where the fan 30 is installed, by gradually decreasing the cross-sectional dimension of the installation cavity 103 in the vertical direction from the position where the fan 30 is installed to the discharge end 103 along the direction from the feed end 101 to the discharge end 103, the consistency of the gas pressure in the installation cavity 103 along the direction from the feed end 101 to the discharge end 103 can be ensured as much as possible, so that the wind power formed by the hot air blown out from the air outlet 104 can be kept as consistent as possible, thereby effectively reducing the shaking of the thin carrier 900.

[0084] Those skilled in the art will understand that the above description and the embodiments of the present application shown in the drawings are only examples and do not limit the present application. The advantages of the present application have been fully and effectively realized. The functions and structural principles of the present application have been shown and described in the embodiments, and the embodiments of the present application can be any deformation or modification without departing from the principles.
