Description

Technical Field

[0001] This utility model relates to the technical field of powder shaker accessories, and in particular to a conveyor belt with end adsorption. Background Technology

[0002] A drying chamber is located at the tail end of the powder-dissolving machine, mainly used to melt the hot melt powder evenly distributed on the printing media to form a transparent protective film, thereby achieving a color-fixing effect. To ensure the uniformity of the protective film thickness, a conveyor belt is used to transfer the printing media within the drying chamber. Referring to patent application CN115302957A, a printer and a printer / powder-dissolving / color-fixing integrated machine including the same, the annular conveyor belt 51 has a negative pressure suction hole 521 inside; the negative pressure suction hole 521 stably adsorbs the printing media onto the surface of the annular conveyor belt 51; however, during the melting of the hot melt powder, the ink on the surface of the printing media also evaporates due to heat, forming smoke. Therefore, a gas collection hood 41 is generally provided at the top of the drying chamber to collect the smoke. This negative pressure suction hole 521 easily forms a suction effect with the gas collection hood 41, weakening the gas collection hood 41's ability to collect smoke, causing some smoke to be discharged along with the printing media; this smoke cannot be purified, posing a threat to the operator's safety.

Preferably, a drive motor is provided at one end of the drive roller; the output shaft of the drive motor is coaxially fixed to the drive roller, providing power for the annular rotation of the annular mesh belt.

[0005] Preferably, the side of the drive roller is evenly distributed with axial friction ridges to increase the friction between the drive roller and the annular mesh belt and prevent the annular mesh belt from slipping.

[0006] Preferably, the inner wall of the annular mesh belt is provided with an inwardly extending retaining ring; both ends of the active roller and the passive roller are equipped with retaining ring end caps; the retaining ring end caps are provided with retaining grooves that correspond to and match the retaining rings; the retaining rings are inserted into the retaining grooves; the retaining rings and retaining grooves cooperate with each other to achieve axial positioning of the annular mesh belt, thereby ensuring that the printing medium does not shift laterally when it flows on the annular mesh belt.

[0007] Preferably, the top of the negative pressure box is positioned higher than the upper side of the active roller and the upper side of the passive roller to ensure that the annular mesh belt is in close contact with the top of the negative pressure box and to ensure that the negative pressure suction is stably applied to the printing medium.

[0017] Example 1: See Figure 1-12 A conveyor belt with end adsorption includes an active roller 1, a passive roller 2, an annular conveyor belt 3, and adsorption components. The annular conveyor belt 3 is connected to the active roller 1 and the passive roller 2 at both ends, enabling it to rotate in an annular manner. Two adsorption components are located inside the annular conveyor belt 3 at both ends, extending beyond the drying chamber. These two adsorption components are located at the inlet and outlet ends of the drying chamber, respectively, adsorbing the printing media and ensuring that the printing media below the drying chamber adheres tightly to the surface of the annular conveyor belt 3 for color fixation. The adsorption components include a negative pressure box 41 and a turbine fan 42. The turbine fan 42 is located at the bottom of the negative pressure box 41, with its input end connected to the negative pressure box 41, providing negative pressure suction. The top of the negative pressure box 41 has a negative pressure hole 411, which connects to the inner wall of the annular conveyor belt 3, enabling it to adsorb the printing media. Compared with the prior art, this utility model is equipped with adsorption components at the inlet and outlet of the drying chamber to adsorb the printing medium, which can avoid the air collection hood of the drying chamber and ensure that the smoke can be smoothly discharged from the air collection hood.

[0018] One end of the drive roller 1 is equipped with a drive motor 11; the output shaft of the drive motor 11 is coaxially fixed to the drive roller 1, providing power for the annular rotation of the annular mesh belt 3.

[0019] The side of the drive roller 1 is evenly distributed with axial friction ribs 12 to increase the friction between the drive roller 1 and the annular mesh belt 3 and prevent the annular mesh belt 3 from slipping.

[0020] The inner wall of the annular mesh belt 3 is provided with an inwardly extending retaining ring 31; both ends of the driving roller 1 and the driven roller 2 are equipped with retaining ring end caps 21; the retaining ring end caps 21 are provided with retaining grooves 211 that correspond to and match the retaining ring 31; the retaining ring 31 is inserted into the retaining groove 211; the retaining ring 31 and the retaining groove 211 cooperate with each other to achieve axial positioning of the annular mesh belt 3, thereby ensuring that the printing medium will not shift laterally when it flows on the annular mesh belt 3.

[0021] The top of the negative pressure box 41 is positioned above the upper side of the active roller 1 and the upper side of the passive roller 2, ensuring that the annular mesh belt 3 is in close contact with the top of the negative pressure box 41, and ensuring that the negative pressure suction acts stably on the printing medium.

[0022] The top of the negative pressure box 41 is positioned between the two retaining rings 31; the width of the top of the negative pressure box 41 is less than the distance between the two retaining rings 31, ensuring that the negative pressure box 41 does not interfere with the retaining rings 31.

[0023] The conveyor belt also includes a connecting platform 46; the two ends of the connecting platform 46 are respectively connected to two negative pressure boxes 41, so that the two negative pressure boxes 41 form a whole, ensuring that the two negative pressure boxes 41 are in stable relative positions, thereby ensuring that the printing medium between the two negative pressure boxes 41 is flat.

[0024] The conveyor belt also includes a Z-shaped plate 43 and a support plate 44; one end of the Z-shaped plate 43 is connected to the frame and the other end is connected to the top edge of the connecting platform 46; one end of the support plate 44 is connected to the frame and the other end abuts against the bottom of the connecting platform 46; the Z-shaped plate 43 and the support plate 44 provide vertical positioning for the connecting platform 46, and also ensure a stable connection between the adsorption components and the frame.

[0025] The number of turbine fans 42 installed in the negative pressure box 41 near the active roller 1 is less than the number installed in the negative pressure box 41 near the passive roller 2. This is beneficial for the active roller 1 to drive the annular mesh belt 3 to rotate, and also prevents the annular mesh belt 3 from slipping at the passive roller 2, which would affect the color fixing effect.

[0026] The bottom of the negative pressure box 41 is slidably connected to a horizontal drawer 412; the turbine fan 42 is installed inside the horizontal drawer 412 and can move with the horizontal drawer 412 for easy maintenance and replacement; the horizontal drawer 412 is provided with a horizontal partition 4121; each turbine fan 42 is provided with a partition 4121 on both sides; each turbine fan 42 is provided with an independent cavity by the partition 4121 so that the negative pressure suction provided by each turbine fan 42 does not interfere with each other; the side of the horizontal drawer 412 is provided with an air outlet A 4122 that corresponds to the output end of the turbine fan 42; the bottom side of the negative pressure box 41 is provided with an air outlet B 413 that corresponds to the air outlet A 4122; the air force output by the turbine fan 42 is discharged through the air outlet A 4122 and the air outlet B 413.

[0028] A Torx screw 4124 is installed on the outer end face of the horizontal drawer 412 as the operating end for pulling out the horizontal drawer 412.

[0029] The working principle of this embodiment is as follows: Adsorption components are installed at the inlet and outlet of the drying chamber to adsorb the printing media, avoiding the air collection hood of the drying chamber and ensuring that smoke can be smoothly discharged from the hood. Axial friction ribs 12 are evenly distributed on the side of the active roller 1 to increase the friction between the active roller 1 and the annular mesh belt 3, preventing slippage of the annular mesh belt 3. The retaining ring 31 and the retaining groove 211 cooperate to achieve axial positioning of the annular mesh belt 3, thereby ensuring that the printing media does not shift laterally when flowing on the annular mesh belt 3. The top of the negative pressure box 41 is positioned higher than the upper side of the active roller 1 and the upper side of the passive roller 2, ensuring that the annular mesh belt 3 is in close contact with the top of the negative pressure box 41, ensuring stable negative pressure suction on the printing media. The connecting platform 46 forms the two negative pressure boxes 41 into a whole, ensuring the relative positional stability of the two negative pressure boxes 41, thereby ensuring the flatness of the printing media between the two negative pressure boxes 41.

[0030] Example 2: Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that: the outer end of the horizontal drawer 412 extends outward to form a baffle 4125; when the horizontal drawer 412 is inserted into the bottom of the negative pressure box 41, the baffle 4125 restricts the insertion depth of the horizontal drawer 412.

[0031] The baffle 4125 is provided with a vertical elongated hole 41251; the conveyor belt also includes a connecting screw 45; the connecting screw 45 passes through the vertical elongated hole 41251 and is threaded to the bottom of the negative pressure box 41 to achieve a fixed connection between the horizontal drawer 412 and the negative pressure box 41.
