Description

Technical Field

[0001] This invention relates to the field of fireworks and firecrackers production equipment, and in particular to an automatic conveyor belt cleaning device and method. Background Technology

[0002] Currently, the filling of inner cylinders in fireworks displays is mostly done by hand. Cleaning is also primarily manual, resulting in low production efficiency and high labor costs. Mechanization, automation, and intelligentization are inevitable trends. Cleaning the conveyor belts in automated inner cylinder filling production lines is difficult and labor-intensive. Summary of the Invention

[0003] This invention provides an automatic conveyor belt cleaning device and method, which can solve the problem of difficult-to-clean debris and various dust and impurities adhering to the inner cylinder of the firework filling production line.

[0004] According to a first aspect of the present invention, an automatic conveyor belt cleaning device is provided, comprising a conveyor belt, a cleaning mechanism and a drive mechanism. The cleaning mechanism includes a cleaning device, a water tank and a squeegee. The cleaning device includes a cleaning head and a swing arm. The drive mechanism drives the cleaning head to move between the water tank and the lower end face of the conveyor belt through the swing arm. The cleaning device periodically cooperates with the lower end face of the conveyor belt and performs cleaning by means of the running power of the conveyor belt.

[0005] In some specific embodiments, the drive mechanism includes a cylinder and a lifting cylinder, wherein the lifting cylinder is disposed below the conveyor belt and mounted on the conveyor frame.

[0006] In some specific embodiments, one end of the swing arm is connected to the cylinder, and the cylinder, water tank and cleaning device are fixed on the mounting base. The cylinder drives the cleaning device to swing up and down between the lower end face of the conveyor belt and the water tank. With this setting, the cleaning device can automatically fall into the water tank to absorb water and moisten after cleaning for a period of time, and then start the next cleaning cycle, thus realizing periodic automatic cleaning.

[0007] In some specific embodiments, a pressure roller is provided at one end of the swing arm, and the lifting cylinder drives the conveyor belt to move up and down. The lower end face of the conveyor belt can be pressed against the pressure roller. With this arrangement, the cleaning device can make close contact with the conveyor belt by means of the pressure roller and perform cleaning by means of the conveyor belt's own power.

[0008] In some specific embodiments, the cleaning device also includes a support column, which is connected to the swing arm via a pivot and fixed to the conveyor frame. This configuration allows the two ends of the swing arm to swing up and down, forming a lever structure.

[0009] In some specific embodiments, the water tank is equipped with a water level control valve, which includes an inlet switch and a drain switch. With this configuration, when the water level in the water tank is lower than the water level line, the drain switch automatically replenishes the water tank with water, and after the work is completed, the water inside can be drained through the drain switch.

[0010] In some specific embodiments, the squeegee is located inside the water tank and at the rear end of the cleaning head along the direction of conveyor belt movement. This arrangement allows the squeegee to remove residual water and debris from the conveyor belt after the cleaning device has cleaned it, using the conveyor belt's own power.

[0011] In some specific embodiments, the squeegee device includes a silicone scraper, an adjustable telescopic rod, a fixed base plate, and a telescopic spring. The telescopic spring is disposed inside the adjustable telescopic rod, and the silicone scraper is connected to the fixed base plate through the adjustable telescopic rod. This arrangement allows the adjustable telescopic rod to be pre-tightened by the telescopic spring, effectively ensuring the contact force between the silicone scraper and the conveyor belt, ensuring clean squeegeeing without hindering the normal operation of the conveyor belt.

[0012] According to a second aspect of the present invention, an automatic cleaning method for conveyor belts is provided, employing the above-described apparatus, comprising the following steps:

[0013] S1: When the conveyor belt transports the cake to the designated position, the conveyor belt stops running, the lifting cylinder lifts the conveyor belt, the pressure roller separates from the lower end face of the conveyor belt, and the cleaning head at the other end of the rocker arm descends into the water tank by its own weight to get wet.

[0014] S2: The lifting cylinder returns to its initial position, the pressure roller presses against the lower end face of the conveyor belt, and the cleaning head is lifted and contacts the lower end face of the conveyor belt.

[0015] S3: The conveyor belt resumes operation. The water-soaked cleaning head uses the power of the conveyor belt to clean the lower end face of the conveyor belt. The scraper removes the water stains and residues remaining after cleaning.

[0016] S4: The conveyor belt transports the next cake, repeating S1 to S3.

[0017] In some specific embodiments, when the water level in the tank is lower than the internal water level line, the water inlet switch automatically replenishes water, and automatically stops when the water level is reached.

[0018] Compared with the prior art, the beneficial effects of this application are as follows:

[0019] The swing arm structure of the automatic conveyor belt cleaning device in this application can clean both fixed and lifting conveyor belts using different drive mechanisms. Furthermore, the scraper in the water tank effectively removes water and residue from the conveyor belt while ensuring contact and force between the silicone scraper and the conveyor belt, achieving clean cleaning without hindering the normal operation of the conveyor belt. This application also discloses an automatic conveyor belt cleaning method, which uses the conveyor belt to transport the cleaning cake to a designated position, and the lifting cylinder periodically rises to enable the cleaning device to perform periodic automatic cleaning. The water level control valve in the water tank automatically replenishes water according to the water level in the tank, ensuring the cleaning device remains moist and improving its cleaning effect.

Figure 6 The diagram shown is a schematic representation of a conveyor belt structure equipped with an automatic cleaning device according to the first embodiment of the present invention. Figure 7 A schematic diagram of the structure of the automatic cleaning device according to the first embodiment of the present invention is shown, and Figure 8 The schematic diagram shown is of an automatic cleaning device with a water tank according to a first embodiment of the present invention. The device will be described in detail below:

[0039] In a specific embodiment, this embodiment has a similar cleaning head 201, mounting adjustment plate 211 and swing arm 202 to the first embodiment, which will not be described again here. The difference is that the other end of the swing arm 202 is connected to the cylinder 203, and the swing arm 202 is connected to the fixing plate 206 through the rotating shaft 212. The fixing plate 206 is mounted on the mounting base 10.

[0040] In a specific embodiment, when the cylinder 203 extends, the cleaning head 201 moves down into the water tank 205 with the swing arm 202 to dip into the water tank 205 and moisten it, ensuring that the cleaning head 201 is wet. When the cylinder 203 returns to its original position, the cleaning head 201 is forced to rise and contact the lower end face of the conveyor belt 100, and is cleaned by the power of the conveyor belt 100 itself.

[0041] In a specific embodiment, this embodiment has a similar wiper device 204 and water tank 205 to the first embodiment, which will not be described again here. The difference is that the wiper device 204 is fixed in the middle of the water tank 205, and the water tank 205 is directly fixed on the mounting base 10.

[0042] Continue to refer to Figure 9 , Figure 9 A schematic diagram of a wiping device according to an embodiment of the present invention is shown, as follows: Figure 9 As shown, the wiping device 204 includes a silicone squeegee 214, a fixed base plate 224, an adjustable telescopic rod 234, and a telescopic spring 244.

[0043] In a specific embodiment, the squeegee device 204 is fixed on the adjusting telescopic rod 234, and the fixed base plate 224 and the adjusting telescopic rod 234 are automatically pre-tightened by the telescopic spring 244 to ensure that the silicone squeegee 214 and the lower end face of the conveyor belt 100 make flexible contact.

[0044] Continue to refer to Figure 10 , Figure 10 A schematic flowchart of an automatic conveyor belt cleaning method according to an embodiment of the present invention is shown, as follows: Figure 10 As shown, the method includes:

[0045] S1: When the conveyor belt transports the cake to the designated position, the conveyor belt stops running, the lifting cylinder lifts the conveyor belt, the pressure roller separates from the lower end face of the conveyor belt, and the cleaning head at the other end of the rocker arm descends into the water tank by its own weight to get wet.

[0046] S2: The lifting cylinder returns to its initial position, the pressure roller presses against the lower end face of the conveyor belt, and the cleaning head is lifted and contacts the lower end face of the conveyor belt.

[0047] S3: The conveyor belt resumes operation. The water-soaked cleaning head uses the power of the conveyor belt to clean the lower end face of the conveyor belt. The scraper removes the water stains and residues remaining after cleaning.

[0048] S4: The conveyor belt transports the next cake, repeating S1 to S3.

[0049] In a specific embodiment, during the long-term cleaning process, the cleaning device periodically dips into water to remove moisture, and the water level in the water tank will continuously drop. If the water level is too low, the cleaning device will not be sufficiently moistened, which will not only affect the cleaning effect, but also easily damage the cleaning device and the conveyor belt. Therefore, the water inlet switch and the water outlet switch of the water tank can effectively control the water level in the water tank to ensure that the water level in the water tank is constant. When the water level is lower than the water level line, the water inlet switch will automatically replenish water, and automatically stop replenishing water when the water level line is reached.

[0050] The swing arm structure of the automatic conveyor belt cleaning device in this application can clean both fixed and lifting conveyor belts using different drive mechanisms. Furthermore, the scraper in the water tank effectively removes water and residue from the conveyor belt while ensuring contact and force between the silicone scraper and the conveyor belt, achieving clean cleaning without hindering the normal operation of the conveyor belt. This application also discloses an automatic conveyor belt cleaning method, which uses the conveyor belt to transport the cleaning cake to a designated position, and the lifting cylinder periodically rises to enable the cleaning device to perform periodic automatic cleaning. The water level control valve in the water tank automatically replenishes water according to the water level in the tank, ensuring the cleaning device remains moist and improving its cleaning effect.

[0051] It is obvious that those skilled in the art can make various modifications and alterations to the embodiments of this application without departing from the spirit and scope of this application. In this way, this application also aims to cover such modifications and alterations if they fall within the scope of the claims and their equivalents. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims. The simple fact that certain measures are described in mutually different dependent claims does not indicate that a combination of these measures cannot be used for profit. Any reference numerals in the claims should not be considered limiting in scope.
