Description

TECHNICAL FIELD

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

[0002] At present, printing equipment is used to print on paper, cloth and other thin carriers 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 dry, a drying process is usually added after the thin carrier is sprayed. 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 also has many defects.

[0004] Firstly, 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. Therefore, the existing oven usually has a fan at one end of the oven through which the thin carrier enters. While the fan directs the hot air to the thin carrier, the hot air will overflow along the outlet of the paper. In this way, it is inevitable to cause a large heat loss. In order to fully utilize the hot air, a fan that blows air towards the end through which the thin carrier enters is sometimes arranged at the end through which the thin carrier exits, so that the hot air can be recycled. However, this method requires two fans, which not only increases the cost of the oven, but also makes the oven too large and heavy.

[0005] More importantly, the two fans blow air towards each other, which will inevitably cause the thin carrier between the two fans to shake violently. In this way, it will cause the ink on the thin carrier to move seriously, thereby affecting the quality and qualification rate of the final product. SUMMARY

[0009] The other advantage of the utility model lies in providing a drying oven capable of reducing vibration, wherein the drying oven capable of reducing vibration has little change on the existing drying oven structure, thereby reducing the cost of reconstruction.

[0010] The other advantage of the utility model lies in providing a drying oven capable of reducing vibration, wherein the hot air circulating drying oven can prevent air pressure disorder caused by a single fan, thereby effectively reducing the shaking amplitude of the thin carrier when being dried via the drying oven.

[0011] The other advantage of the utility model lies in providing a drying oven capable of reducing vibration, wherein the drying oven capable of reducing vibration can realize hot air circulation by arranging one fan, and therefore, the drying oven capable of reducing vibration can realize heat recycling while relatively reducing the volume and weight of the drying oven.

[0039] refer to Figures 1 to 9 A preferred embodiment of the present invention, an oven with reduced vibration, will be described in detail below. This oven is capable of drying a thin carrier 900 and can circulate hot air. Those skilled in the art will understand that the thin carrier 900 can be paper, canvas, etc., and the present invention is not limited thereto.

[0040] Specifically, the vibration-reducing oven includes a housing 10, wherein the housing 10 has a feed end 101 and a discharge end 102, wherein the thin carrier 900 is movable via the feed end 101 toward the discharge end 102.

[0041] The housing 10 forms an installation cavity 103 between the feed end 101 and the discharge end 102, and the housing 10 also forms a set of air outlets 104 communicating with the installation cavity 103 at the top of the installation cavity 103 between the feed end 101 and the discharge end 102.

[0042] Preferably, the air outlet 104 is oriented obliquely toward the discharge end 102 to prevent the air from the air outlet 104 from blowing vertically toward the thin carrier 900 and causing the thin carrier 900 to be subjected to excessive pressure.

[0043] Preferably, the distance from the feed end 101 to the discharge end 102 is defined as a transverse direction, wherein each of the air outlets 104 is provided to extend along a longitudinal direction perpendicular to the transverse direction, so that the hot air generated by the vibration-reducing oven can cover the entire longitudinal width of the thin carrier 900. That is, the air outlet 104 is a long and narrow opening extending along the longitudinal direction.

[0044] Preferably, the housing 10 forms a plurality of air outlets 104, wherein the plurality of air outlets 104 are arranged at intervals along the transverse direction to increase the area of ​​the vibration-reducing oven capable of drying the thin carrier 900. More preferably, the plurality of air outlets 104 are arranged at equal intervals along the transverse direction.

[0045] Specifically, the box body 10 has a box main body 11 and an air outlet plate 12, wherein the top of the box main body 11 corresponds to the position of the installation cavity 103, and the air outlet plate 12 covers the top of the installation cavity 103 and forms the air outlet 104.

[0046] The vibration-reducing oven includes at least one set of heat generators 20 and at least one fan 30. The fan 30 is arranged in the installation cavity 103 of the box body 10 near the feeding end 101. The heat generators 20 are also arranged in the installation cavity 103 and located on the flow path of the flowing air formed by the fan 30.

[0047] The fan 30 is arranged to guide the air from the feeding end 101 to the discharging end 102. During the process of guiding the air from the feeding end 101 to the discharging end 102 by the fan 30, the air is heated by the heat generators 20, and the hot air can be guided out through the air outlet 104. The hot air formed after being heated by the heat generators 20 can flow out from the air outlet 104 to dry the ink on the thin carrier 900 opposite to the air outlet 104. Preferably, the fan 30 is arranged near the feeding end 101.

[0048] As a preferred embodiment, the vibration-reducing oven includes 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 uniformly dried.

[0049] It is worth mentioning that the box body 10 of the vibration-reducing oven, preferably at least one of the two sides in the longitudinal direction of the installation cavity 103, forms at least one return air passage 105 separated from the installation cavity 103 and a set of return air holes 106 communicating with the return air passage 105, wherein the return air holes 106 are arranged on the top of the return air passage 105, and a set 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 near the feeding end 101.

[0050] As preferred, at least one return air passage 105 is formed on each of the two sides of the housing 10 in the longitudinal direction of the installation cavity 103, and a set of return air holes 106 is formed in communication with the return air passage 105. In this way, after the hot air is discharged 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 the negative pressure formed by the fan 30 near the feeding end 101, and then continuously flow to the air inlet of the fan 30.

[0051] In this way, the hot air can be effectively recycled and utilized.

[0052] As preferred, the housing 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.

[0053] The fan 30 is installed in the first installation cavity 1031. In a preferred embodiment, a plurality of 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 return air holes 106 can be more guided to the second installation cavity 1032 by the fan 30 through the communication passage 108.

[0054] As can be understood by those skilled in the art, through such an arrangement, the vibration-reducing oven can achieve the recycling of hot air without arranging two fans that blow air in opposite directions.

[0055] Further preferably, the housing 10 further comprises a return air plate 14, wherein the return air plate 14 is arranged at the discharging end 102, and the return air plate 14 is arranged to extend upwardly and tilt towards the feeding end 101. At the same time, the housing 10, i.e. the air outlet plate 12, forms a return air outlet 109 between the return air plate 14 and the feeding end 101, and near the return air plate 14.

[0056] As preferred, the return air outlet 109 and the return air 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 104 to the discharge end 102, a portion of the hot air will return to the installation cavity 103 from the return air outlet 109 due to the blocking of the return air plate 14. In a preferred embodiment, the return air passage 105 is in communication with the installation cavity 103 near the discharge end 102, and the return air outlet 109 is in communication with the return air passage 105. In this way, the hot air returned from the return air outlet 109 can also flow to the air inlet of the fan 30 through the return air passage 105.

[0057] As preferred, in an embodiment, the 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 guided from the air outlet 104 can be reduced to be excessively guided back from the return air hole 106, which not only ensures that the thin carrier 900 near the fan 30 can be sufficiently dried by the hot air, but also enables the hot air to be circulated and returned.

[0058] In another embodiment, the spacing between two adjacent return air holes 107 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 also be reduced to be interfered.

[0059] 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 carrier passage 109 with the air outlet plate 12 for the thin carrier 900 to pass through.

[0060] 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. It can be understood by those skilled in the art 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.

[0061] More preferably, one side of the cover plate 15 towards the air outlet 104 forms an arc surface 1501, which is used to abut the side of the thin carrier 900 on which the ink is printed. In addition, the arc surface 1501 is provided with an anti-wrinkle structure 40.

[0062] 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 lateral 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.

[0063] By such an arrangement, while the thin carrier 900 is dried via the vibration-reducing 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 inward when being dried. By arranging the anti-wrinkle structure 40, the degree of the thin carrier 900 shrinking inward when being dried can be effectively reduced, because the anti-wrinkle structure 40 gives the thin carrier 900 a force to expand outward when being dried.

[0064] 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 pair of ribs 41 near the side of the arc surface 1501 along the longitudinal direction is larger.

[0065] More preferably, a plurality of pairs of anti-wrinkle structures 40 are arranged along the lateral direction.

[0066] 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.

[0067] 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.

[0068] 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.
