Description

Technical Field

[0001] The invention relates to the technical field of glass silk-screen printing, and in particular to a glass silk-screen printing drying and dust-proof device. Background Art

[0002] Glass silk screen printing is an important process in glass processing. It realizes personalized decoration of glass by printing patterns, logos and other decorative elements on the glass surface. Glass silk screen printing is a technology that uses a screen printing plate to perform decorative printing on glass products. It is to print ink on the surface of glass and make the pattern firmly attached to the glass through certain curing measures (such as high temperature firing). When the drying device is running, it is necessary to introduce outside air for heat exchange or to maintain air circulation inside the equipment. These outside air often contain a certain amount of impurities such as dust and particles, which may adhere to the surface of the glass silk screen after entering the drying device.

[0003] In the prior art, a Chinese patent with the authorization announcement number CN212889430U discloses a glass screen printing drying dust prevention device, including a drying box, a heater is fixedly connected to the top of the drying box, the bottom of the heater is penetrated into the inner cavity of the drying box through a conduit and connected to a drying pipe, and a motor is fixedly connected to the bottom of the inner cavity of the drying box. The airflow generated by the rotation of the fan blows up the dust in the drying box, and the vacuum cleaner transports the dust gas generated in the drying box to the dustproof box through the suction pipe, the suction hood and the exhaust pipe, thereby reducing the dust accumulation in the drying box.

[0004] The disadvantages of the above-mentioned prior art solutions are that: when the fan blows up dust, if the wind speed is improperly controlled or the suction force of the vacuum cleaner is not enough to quickly suck all the dust, some dust and other impurities are easily deposited on the ink surface, thereby affecting the quality of glass screen printing. At the same time, the dust gas in the drying box has a certain temperature, and directly discharging it to the outside will indeed cause heat loss and waste, and this heat loss leads to low energy utilization efficiency.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figures 1 to 7As shown, a glass silk-screen drying and dust-proof device comprises a workbench 1, a drying mechanism 2, a dust-proof mechanism 3 and a transport mechanism 4. The drying mechanism 2 comprises a drying box 21, which is fixedly arranged on the top of the workbench 1. The drying box 21 is provided with a drying component 22 for drying the silk-screen on the glass surface. The dust-proof mechanism 3 includes a dust collecting box 31, an air collecting hood 32, a fan 33 and an air outlet duct 34. A dust collecting chamber is provided in the dust collecting box 31. An air inlet 35 and an air outlet 36 connected to the dust collecting chamber are respectively provided on the top and the side of the dust collecting box 31. The air collecting hood 32 and the air outlet duct 34 are arranged in the drying box 21, and the air collecting hood 32 is located at the top of the drying box 21. The air collecting hood 32 is connected to the air inlet 35, the input end of the fan 33 is connected to the air outlet 36, and the output end of the fan 33 is connected to the air outlet duct 34. A filter component 37 for filtering dust is provided in the dust collecting chamber, and an adjustment component 38 for adjusting the position of the air outlet duct 34 and the air outlet direction is provided in the drying box 21. The transport mechanism 4 includes a conveyor belt 41, which is arranged on the top of the workbench 1 and below the drying box 21. A feed port 42 and a discharge port 43 are respectively provided on both sides of the drying box 21. A sliding baffle 44 is provided at the ends of the feed port 42 and the discharge port 43.

[0031] The glass products to be dried are placed on the conveyor belt 41 and enter the drying box 21 through the feed port 42. The baffles 44 at the ports of the feed port 42 and the discharge port 43 slide down to form a relatively closed space in the drying box 21 to prevent external dust from entering the drying box 21. Then, the drying component 22 set in the drying box 21 is started to evenly heat and dry the silk-screen pattern on the glass surface. In this process, the heat generated by the drying component 22 directly acts on the glass surface to accelerate the curing and drying of the ink.

[0032] During the drying process, the dust and tiny particles generated in the drying box 21 are captured by the air collecting hood 32. The air collecting hood 32 is located at the top of the drying box 21, and uses its location advantage to effectively collect the rising hot air and entrained dust. After the fan 33 is started, the dust-containing gas is sucked in through the air outlet 36 of the dust collecting box 31, and filtered by the filter component 37 in the dust collecting chamber, so that the dust is intercepted in the dust collecting chamber, and the clean gas is discharged into the drying box 21 through the air outlet pipe 34 for recycling, thereby reducing the direct leakage of heat in the drying box 21 and improving energy utilization efficiency.

[0033] At the same time, by adjusting the position of the air outlet duct 34, the heat exchange process between the hot air and the glass substrate can be optimized, so that the heat is more evenly distributed on the glass substrate, the temperature gradient during the drying process is reduced, and the problem of local overheating or uneven drying is avoided. By adjusting the air outlet direction of the air outlet duct 34, the hot air can form a more uniform airflow distribution in the drying box 21, avoiding the situation of local overheating or uneven drying. This is very important for ensuring the drying quality of glass silk printing, and can reduce the quality problems caused by uneven drying. In addition, adjusting the air outlet direction of the air outlet duct 34 can also make the air flow direction maintain a certain angle with the ink on the glass surface, which can guide dust away from the ink on the glass surface to a certain extent to reduce the adhesion of impurities such as dust.

[0034] After the drying is completed, the baffles 44 at the ports of the feed port 42 and the discharge port 43 slide upward, and then the conveyor belt 41 sends the dried glass products out of the drying box 21 .

[0035] refer to Figure 2 and Figure 5 As shown, in some specific embodiments, the adjustment assembly 38 includes a slide rail 39, a sliding bracket 310, a screw 311 and a rotating motor 315. The slide rail 39 is fixedly connected to the drying box 21 in a horizontal state. The sliding bracket 310 is slidably connected to the slide rail 39. The screw 311 is rotatably arranged in the slide rail 39. The sliding bracket 310 is provided with a rotating hole threadedly matched with the screw 311. The air outlet pipe 34 is rotatably connected to the bottom of the sliding bracket 310. The bottom of the sliding bracket 310 is provided with a locking member 312 for locking the rotation of the air outlet pipe 34. The locking member 312 includes a locking rod. The bottom of the sliding bracket 310 is provided with a plurality of adjusting holes 313 arranged in an annular shape. The side of the air outlet pipe 34 is provided with a positioning hole 314. The locking rod is penetrated and arranged in the adjusting hole 313 and the positioning hole 314. The rotating motor 315 is fixedly connected to the drying box 21. The output end of the rotating motor 315 is coaxially fixedly connected with the screw 311.

[0036] The rotating motor 315 is started, and the output end of the rotating motor 315 drives the screw rod 311 to rotate. Since the screw rod 311 is threadedly matched with the rotating hole of the sliding bracket 310, the rotation of the screw rod 311 is converted into a linear movement of the sliding bracket 310 on the slide rail 39. By controlling the rotation direction and rotation time of the rotating motor 315, the horizontal position of the sliding bracket 310 and the air outlet pipe 34 in the drying box 21 can be accurately adjusted.

[0037] At the bottom of the sliding bracket 310, the air outlet pipe 34 can rotate within a certain range relative to the sliding bracket 310. After the air outlet pipe 34 is rotated to the desired angle, it is locked using the locking member 312. The locking rod is inserted into the corresponding adjustment hole 313 and positioning hole 314 to fix the rotation position of the air outlet pipe 34, ensuring that the air outlet pipe 34 will not rotate due to external force during the drying process. When the air outlet direction needs to be adjusted, the locking rod can be pulled out from the adjustment hole 313 and positioning hole 314.

[0038] refer to Figure 5 As shown, in some specific embodiments, the sliding bracket 310 includes a sliding base 316, a fixed bracket 317 and a movable bracket 318, the sliding base 316 is slidably connected with the slide rail 39, the sliding base 316 is provided with a rotating hole threadedly matched with the screw rod 311, the fixed bracket 317 is fixedly connected with the sliding base 316, the fixed bracket 317 is provided with a vertical slide groove, the movable bracket 318 is slidably connected with the slide groove, the air outlet pipe 34 is rotatably connected with the bottom of the movable bracket 318, and the bottom of the movable bracket 318 is provided with a locking member 312 for locking the rotation of the air outlet pipe 34. The locking member 312 includes a locking rod, the bottom of the movable bracket 318 is provided with a plurality of annularly arranged adjustment holes 313, the side of the air outlet pipe 34 is provided with a positioning hole 314, and the locking rod is arranged through the adjustment hole 313 and the positioning hole 314.

[0039] When the rotating motor 315 drives the screw rod 311 to rotate, the screw rod 311 is threadedly matched with the rotating hole on the sliding base 316, and the sliding base 316 moves linearly along the slide rail 39, thereby changing the horizontal position of the air outlet duct 34 in the drying box 21. By adjusting the position of the movable bracket 318 in the slide groove, the height of the air outlet duct 34 can be fine-tuned to adapt to drying scenes with different height requirements. When the air outlet duct 34 is rotated to the desired angle, the locking rod is inserted into the corresponding adjustment hole 313 and positioning hole 314 to fix the rotation position of the air outlet duct 34. When the air outlet direction needs to be adjusted, the locking rod can be unlocked by simply pulling it out from the adjustment hole 313 and the positioning hole 314.

[0040] Through the cooperation between the sliding base 316 and the slide rail 39, the cooperation between the fixed bracket 317 and the movable bracket 318, and the rotation cooperation between the air outlet pipe 34 and the movable bracket 318, the precise adjustment of the position and the air outlet direction of the air outlet pipe 34 is achieved, so that the drying device can more flexibly adapt to the drying of glass products with different sizes and height requirements, and improve the versatility and flexibility of the drying device.

[0041] refer to Figure 3As shown, in some specific embodiments, the filter assembly 37 includes an insert plate 319 and a filter screen 320. A through groove is provided on the top of the insert plate 319, and the filter screen 320 is fixedly arranged in the through groove. A plurality of longitudinally arranged slots 321 are provided on the side of the dust box 31, and a plurality of insert plates 319 are provided, and are respectively arranged in corresponding slots 321.

[0042] When the hot air with dust in the drying box 21 passes through the dust box 31, it will first pass through the filter 320. The filter 320 can effectively block the particles in the air, allowing clean air to pass and continue to flow. The blocked particles will adhere to the filter 320 and gradually accumulate to form dust. When the filter 320 accumulates too much dust and affects the filtering effect, you only need to remove the plug plate 319 from the slot 321 to easily replace the new filter 320, which greatly reduces the maintenance cost and time.

[0043] refer to Figure 3 As shown, in some specific embodiments, the filter assembly 37 also includes a sealing rubber ring 322, a sealing groove is opened at the end of the slot 321, a sealing plate matching the sealing groove is fixedly provided at one end of the plug plate 319, and the sealing rubber ring 322 is fixedly set in the sealing groove.

[0044] When the plug board 319 is inserted into the slot 321 of the dust box 31, the sealing plate at one end of the plug board 319 will fit tightly with the sealing groove at the end of the slot 321. At this time, the sealing rubber ring 322 fixed in the sealing groove will play a sealing role to ensure that there is no air leakage at the connection between the plug board 319 and the slot 321.

[0045] refer to Figure 4 As shown, in some specific embodiments, the drying assembly 22 includes a plurality of electric heating rods, which are arranged in a matrix in the drying box 21 .

[0046] When the electric heating rod is powered on, the current passes through the electric heating element to generate heat, converting electrical energy into thermal energy. The generated heat is transferred to the air in the drying box 21 and the glass products to be dried through the surface of the electric heating rod. The air circulates in the drying box 21, distributing the heat evenly to the entire drying space.

[0047] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention is now described in combination with specific application scenarios:

[0048] In actual use, first, a number of glass products to be dried are placed on the conveyor belt 41 in sequence to ensure that they are stable and have appropriate spacing. Then, the conveyor belt 41 is started to feed the glass products one by one into the drying box 21. When the glass products reach the feed port 42, the baffle 44 of the feed port 42 slides down to close the drying box 21.

[0049] The electric heating rod in the drying box 21 starts to work, generating heat to evenly heat and dry the silk screen on the glass surface. The dust and tiny particles generated during the drying process are captured by the air collecting hood 32 and sucked into the dust collecting box 31 through the fan 33. After the dust is filtered by the filter 320, the clean gas with a certain temperature is discharged into the drying box 21 through the air outlet pipe 34 for recycling. According to the drying requirements, the screw 311 is driven to rotate by the rotating motor 315, and the horizontal position and height of the sliding bracket 310 and the air outlet pipe 34 in the drying box 21 are adjusted, and the air outlet direction of the air outlet pipe 34 is adjusted to ensure that the heat exchange process between the hot air and the glass substrate is optimized.

[0050] When the drying is completed, the baffle 44 of the discharge port 43 slides upward, and the conveyor belt 41 continues to run to send the dried glass products out of the drying box 21.

[0051] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
