Description

Technical Field

[0001] This invention relates to the field of cement production and packaging technology, specifically to a cement packaging and conveying device with dust removal function. Background Technology

[0002] Cement packaging and conveying equipment is mainly used for packaging and conveying cement. Its main function is to transfer the produced cement into packaging bags, and then transport it to the appropriate location via conveyor belts. The cement packaging process not only affects product quality and safety, but also has a significant impact on production efficiency, transportation costs, and market image. Currently, the equipment used in cement packaging is divided into fixed packaging machines and rotary packaging machines. Fixed packaging machines are widely used in cement plants due to economic and size considerations. To prevent dust from flying around during use, many dust prevention measures have been introduced for cement packaging equipment on the market. For example, the patent "Publication No. CN115108057A A High-Efficiency Dust-Removing Cement Processing and Packaging Machine" discloses a dust removal method. However, in actual use, this dust removal method still has the following shortcomings: low working efficiency, making it difficult to use in automated production lines; during the cleaning of the inner wall of the dust cover, the sealed space formed by the three dust covers will be connected to the external environment, and the dust adhering to the inner wall of the dust cover may escape into the external environment, thus polluting the external environment; finally, after the current cement packaging equipment finishes working, cement residue will remain on the inner wall of the discharge end. When the packaging bag is removed, the cement residue on the inner wall of the discharge end often falls onto the conveyor belt, thus polluting the working environment. The current cement packaging equipment does not have an effective treatment measure for this. Summary of the Invention

[0003] The purpose of this invention is to provide a cement packaging and conveying device with dust removal function to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cement packaging conveying device with dust removal function, the cement packaging conveying device including a mounting frame, a feeding mechanism, a conveying mechanism, and a dust prevention mechanism, the feeding mechanism including a hopper, a feeding funnel, a valve, and a discharging rack, the hopper being mounted on the mounting frame and connected to an external cement production line, the feeding funnel, valve, and discharging rack being sequentially arranged below the hopper, the conveying mechanism being arranged below the mounting frame, and the dust prevention mechanism including a fixed plate, a dust suction pipe, a fixed dustproof plate, a dust removal rod, and a movable dustproof plate, the fixed plate being positioned near the feeding funnel. At one end of the valve, the suction pipe passes through the fixed plate and connects to an external vacuum cleaner. Two sets of fixed dustproof plates are arranged opposite each other at the lower ends of the fixed plate. Two sets of movable dustproof plates are arranged opposite each other on the outer sides of the two sets of fixed dustproof plates. The dust removal rod is located inside one set of fixed dustproof plates. A first rotary motor is located above the fixed plate, and a second rotary motor is located below the fixed plate. The first rotary motor is connected to the two sets of movable dustproof plates via a first transmission assembly, and the second rotary motor is connected to the dust removal rod via a second transmission assembly. The two sets of fixed dustproof plates and two sets of movable dustproof plates are connected and contact the conveying mechanism. When not in operation, the two sets of movable dustproof plates are located on the side away from the two sets of fixed dustproof plates. When in operation, the packaging bag is fixed below the discharge rack, and then the first rotary motor is turned on. This causes the two sets of movable dustproof plates to rotate. Once the two sets of fixed dustproof plates and the two sets of movable dustproof plates form a sealed working space, the operator can open the valve and the external vacuum cleaner. The valve allows the cement in the hopper to fall into the packaging bag, and the external vacuum cleaner disperses it into the working space. The dust is sucked away to avoid environmental pollution. After the cement is discharged, the workers can drive the dust removal rod to rotate through the second rotary motor. During the rotation, the dust removal rod can remove the dust adhering to the inner walls of the two sets of fixed dustproof plates and the two sets of movable dustproof plates. Compared with the dust removal operation method currently used in cement packaging machines, this invention has higher work efficiency and can be used for automated production line production. On the other hand, during the dust removal process, the working space is always isolated from the external environment, thus avoiding the phenomenon of dust overflowing when cleaning the inner walls of the two sets of fixed dustproof plates and the two sets of movable dustproof plates.

[0005] Furthermore, the cement packaging conveying device also includes a sealing mechanism and a bag feeding mechanism. The sealing mechanism is located to the side of the feeding mechanism and on the conveying mechanism. The bag feeding mechanism is located on the side of the feeding mechanism away from the sealing mechanism. The line connecting the sealing mechanism and the bag feeding mechanism is perpendicular to the line connecting the two sets of fixed dustproof plates (the functions and structures achieved by the sealing mechanism and the bag feeding mechanism are conventional technical means in this field, and the specific working principle is not described). Workers can manually transport the packaging bags to the bottom of the discharge rack through the bag feeding mechanism. After the cement packaging is completed, the conveying mechanism moves the packaging bags filled with cement to the position of the sealing mechanism, and the sealing mechanism seals the packaging bags.

[0006] Furthermore, a bracket is provided below the fixed plate. There are two sets of brackets, which are arranged opposite each other on both sides of the discharge rack. A pressure plate is provided on the side of the lower end of the two sets of brackets that is close to each other, and a cylinder is provided on the side of the lower end of the two sets of brackets that is far from each other. Each set of pressure plates is connected to the working end of a set of cylinders. The two sets of cylinders drive the two sets of pressure plates to move relative to each other. On the one hand, this makes it easier to fix the packaging bag below the discharge rack, so as to prevent the packaging bag from moving when the cement falls into the packaging bag. On the other hand, it reduces the probability of cement being discharged from the packaging bag and reduces cement spillage.

[0007] Furthermore, both the first transmission assembly and the second transmission assembly are disposed inside the fixed disk. The first transmission assembly includes a first internal gear and a first transmission gear, which mesh with the first transmission gear. The working end of the first rotary motor is connected to the first transmission gear. Both sets of movable dustproof plates are fixedly installed at the lower end of the first internal gear. The second transmission assembly includes a second transmission gear and a second internal gear, which mesh with the second internal gear. The working end of the second rotary motor is connected to the second transmission gear. The dust removal rod is fixedly installed at the lower end of the second internal gear. During operation, the first rotary motor drives the first internal gear and the two sets of movable dustproof plates to rotate through the first transmission gear, so that the two sets of fixed dustproof plates and the two sets of movable dustproof plates can form a sealed working space. The second rotary motor drives the second internal gear and the dust removal rod to rotate through the second transmission gear, so as to clean the inner walls of the two sets of fixed dustproof plates and the two sets of movable dustproof plates. In this invention, a sponge is wrapped around the outside of the dust removal rod. The sponge is in a compressed state when in contact with the fixed dustproof plate, thereby preventing the sponge from failing to contact the movable dustproof plate.

[0008] Furthermore, the inside of the feeding funnel is equipped with a feeding component, and the inside of the discharge rack is equipped with a vibration component. The feeding component has a quantitative discharge function and a crushing function, and the vibration component cleans the cement residue on the inner wall of the discharge rack.

[0009] Furthermore, the vibration assembly includes a fixed shaft, a vibrating ball, an electromagnet, and a discharge nozzle. The lower end of the discharge frame has a movable groove, and the upper part of the movable groove has a lifting groove. The fixed shaft is located inside the discharge frame. The vibrating ball is located at the top of the lifting groove, and the electromagnet is located at the bottom of the lifting groove. The upper end of the discharge nozzle is located between the vibrating ball and the electromagnet. A fixing block is located on the lower exterior of the discharge nozzle. The fixing block is movably installed in the movable groove via a telescopic spring rod. The fixed shaft is connected to the vibrating ball via a push rod. The upper end of the discharge nozzle is made of magnetic metal. The discharge nozzle is controlled by an electromagnet and a telescopic spring rod to lower and raise. When cement needs to be delivered into the packaging bag, the electromagnet causes the discharge nozzle to extend into the packaging bag. When cement does not need to be delivered into the packaging bag, the operator can turn off the electromagnet. Under the action of the telescopic spring rod, the discharge nozzle will rise and collide with the vibrating ball. Finally, the discharge nozzle and the discharge rack will vibrate, and the cement adhering to the inner wall of the discharge nozzle and the discharge rack will automatically fall into the packaging bag. Through the above technical solution, it is avoided that the cement remaining in the discharge rack will fall onto the conveying mechanism when the packaging bag is removed, thereby polluting the working environment.

[0010] Furthermore, the feeding assembly includes a feeding motor, a support frame, a transmission disc, and a feeding screw. The support frame is located inside the upper part of the feeding funnel and has several sets of through holes. The feeding motor is mounted on the support frame, and the transmission disc is located inside the support frame. One end of the feeding screw is mounted on the transmission disc, and the other end is located at the end of the feeding funnel near the valve. The cement lumps in the hopper are intercepted through the several sets of through holes. The feeding motor drives the feeding screw to rotate. When the feeding screw rotates, the cement in the feeding funnel falls into the valve. By controlling the number of rotations of the feeding screw, the operator can achieve the purpose of quantitative discharge, ensuring that the amount of cement in each packaging bag is consistent.

[0011] Furthermore, the feeding assembly also includes crushing blades, and several sets of crushing blades are provided. All sets of crushing blades are mounted on the support frame and fixedly connected to the transmission disc. When the feeding motor drives the feeding screw to rotate, the crushing blades rotate synchronously. The crushing blades can crush the cement lumps trapped above the support frame, preventing cement lumps from falling into the packaging bag and affecting the quality of the product. On the other hand, the crushing blades can prevent the several sets of through holes on the support frame from being blocked by large pieces of cement when they rotate.

[0012] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: Compared with current cement packaging conveying devices, this invention is equipped with two sets of movable dustproof plates, two sets of fixed dustproof plates, and one set of dust removal rods. The position of the two sets of movable dustproof plates is controlled by a first rotary motor. When the two sets of fixed dustproof plates and the two sets of movable dustproof plates form a sealed working space, it can prevent dust generated during cement packaging from entering the external environment, thereby preventing environmental pollution. The dust removal rods can be controlled by a second rotary motor to remove dust adhering to the inner walls of the two sets of fixed dustproof plates and the two sets of movable dustproof plates. Compared with the dust removal operation method used in current cement packaging machines, this invention has higher work efficiency and can be used for automated production lines. Furthermore, during the dust removal process, the working space of this invention remains isolated from the external environment. This invention provides a feeding component to ensure consistent cement quantity in each bag and prevent lumps of cement from entering the bags, thus avoiding dust spillage during cleaning of the inner walls of the two sets of fixed and two sets of movable dustproof plates. The feeding component also features a crushing function to ensure the quality of cement entering the bags. Finally, the invention includes a vibration component. When the cement in the bags reaches the designated amount, the vibration component causes cement adhering to the discharge nozzle and the inner wall of the discharge rack to automatically fall into the bags, preventing residual cement from falling onto the conveying mechanism and contaminating the working environment when the bags are removed.

[0016] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] Please see Figures 1-9This invention provides a technical solution: a cement packaging conveying device with dust removal function. The cement packaging conveying device includes a mounting frame 1, a feeding mechanism 2, a conveying mechanism 3, and a dust prevention mechanism 5. The feeding mechanism 2 includes a hopper 21, a feeding funnel 22, a valve 23, and a discharge rack 24. The hopper 21 is mounted on the mounting frame 1 and connected to an external cement production line. The feeding funnel 22, valve 23, and discharge rack 24 are sequentially arranged below the hopper 21. The conveying mechanism 3 is located below the mounting frame 1. The dust prevention mechanism 5 includes a fixed plate 51, a dust suction pipe 52, a fixed dustproof plate 53, a dust removal rod 54, and a movable dustproof plate 55. The fixed plate 51 is located at the end of the feeding funnel 22 near the valve 23, and the dust suction pipe 52 passes through the fixed plate 51. It is connected to an external vacuum cleaner. Two sets of fixed dustproof plates 53 are provided, which are arranged opposite each other at the lower ends of the fixed plate 51. Two sets of movable dustproof plates 55 are provided, which are arranged opposite each other on the outside of the two sets of fixed dustproof plates 53. The dust removal rod 54 is arranged on the inside of one set of fixed dustproof plates 53. A first rotary motor 511 is provided above the fixed plate 51, and a second rotary motor 516 is provided below the fixed plate 51. The first rotary motor 511 is connected to the two sets of movable dustproof plates 55 through a first transmission assembly, and the second rotary motor 516 is connected to the dust removal rod 54 through a second transmission assembly. Both sets of fixed dustproof plates 53 and two sets of movable dustproof plates 55 are in contact with the conveying mechanism 3.

[0018] like Figures 1-2 As shown, the cement packaging conveying device also includes a sealing mechanism 4 and a bag feeding mechanism 6. The sealing mechanism 4 is located to the side of the feeding mechanism 2 and on the conveying mechanism 3. The bag feeding mechanism 6 is located on the side of the feeding mechanism 2 away from the sealing mechanism 4. The line connecting the sealing mechanism 4 and the bag feeding mechanism 6 is perpendicular to the line connecting the two sets of fixed dustproof plates 53. (The functions and structures achieved by the sealing mechanism 4 and the bag feeding mechanism 6 are conventional technical means in this field, and the specific working principle is not described.)

[0019] like Figure 3 As shown, a bracket 56 is also provided below the fixed plate 51. There are two sets of brackets 56, which are arranged opposite each other on both sides of the discharge rack 24. A pressure plate 561 is provided on the side of the lower end of the two sets of brackets 56 that is close to each other, and a cylinder 562 is provided on the side of the lower end of the two sets of brackets 56 that is far apart from each other. Each pressure plate 561 is connected to the working end of a cylinder 562.

[0020] like Figures 4-6As shown, both the first transmission assembly and the second transmission assembly are located inside the fixed disk 51. The first transmission assembly includes a first internal gear 512 and a first transmission gear 513. The first internal gear 512 meshes with the first transmission gear 513. The working end of the first rotary motor 511 is connected to the first transmission gear 513. Both sets of movable dustproof plates 55 are fixedly installed at the lower end of the first internal gear 512. The second transmission assembly includes a second transmission gear 514 and a second internal gear 515. The second transmission gear 514 meshes with the second internal gear 515. The working end of the second rotary motor 516 is connected to the second transmission gear 514. The dust removal rod 54 is fixedly installed at the lower end of the second internal gear 515. The outer side of the dust removal rod 54 is wrapped with sponge.

[0021] When not in operation, the two sets of movable dustproof plates 55 are located on the side away from each other by the two sets of fixed dustproof plates 53. When in operation, the worker can manually transport the packaging bag to the bottom of the discharge rack 24 using the bag feeding mechanism 6. Then, the two sets of cylinders 562 drive the two sets of pressure plates 561 to move closer together, fixing the packaging bag below the discharge rack 24. Next, the first rotary motor 511 is turned on, driving the first internal gear 512 and the two sets of movable dustproof plates 55 to rotate via the first transmission gear 513. Once the two sets of fixed dustproof plates 53 and the two sets of movable dustproof plates 55 form a sealed working space, the worker can open the valve 23 and the external vacuum cleaner. The cement in the hopper 21 falls into the packaging bag through the valve 23, and the external vacuum cleaner removes any dust that has escaped into the working space to prevent environmental pollution. After the cement is discharged, the worker can drive the second internal gear 515 and the dust removal rod 54 using the second rotary motor 516. During the rotation of the dust removal rod 54, the sponge wrapped around its outer side comes into contact with the inner walls of the two sets of fixed dustproof plates 53 and the two sets of movable dustproof plates 55. The sponge removes dust adhering to the inner walls of these plates. Compared to the dust removal methods currently used in cement packaging machines, this invention offers higher efficiency and can be used in automated production lines. Furthermore, during the dust removal process, the working space remains separate from the outside environment. The environment is always isolated, thus avoiding dust overflow when cleaning the inner walls of the two sets of fixed dustproof plates 53 and the two sets of movable dustproof plates 55. Finally, after cleaning the inner walls of the two sets of fixed dustproof plates 53 and the two sets of movable dustproof plates 55, the invention drives the two sets of movable dustproof plates 55 to return to their non-working state by the first rotary motor 511. At this time, the conveying mechanism 3 moves the packaging bag filled with cement to the position of the sealing mechanism 4, and the sealing mechanism 4 seals the packaging bag.

[0022] like Figure 3 , Figures 7-8As shown, the inside of the feed hopper 22 is provided with a feed assembly 221, and the inside of the discharge rack 24 is provided with a vibration assembly.

[0023] like Figure 7 As shown, the vibration assembly includes a fixed shaft 241, a vibrating ball 242, an electromagnet 244, and a discharge nozzle 245. The lower end of the discharge rack 24 is provided with a movable groove, and the upper part of the movable groove is provided with a lifting groove 243. The fixed shaft 241 is located inside the discharge rack 24. The vibrating ball 242 is located at the top inside the lifting groove 243. The electromagnet 244 is located at the bottom inside the lifting groove 243. The upper end of the discharge nozzle 245 is located between the vibrating ball 242 and the electromagnet 244. The lower end of the discharge nozzle 245 is provided with a fixing block 2451. The fixing block 2451 is movably installed in the movable groove by a telescopic spring rod. The fixed shaft 241 is connected to the vibrating ball 242 by a top rod. The upper end of the discharge nozzle 245 is made of magnetic metal.

[0024] When the worker conveys the packaging bag to the bottom of the discharge rack 24, the worker activates the electromagnet 244, which generates a magnetic field to lower the discharge nozzle 245 until it enters the packaging bag. Then, two sets of cylinders 562 drive two sets of pressure plates 561 to move closer together, fixing the packaging bag to the outer wall of the discharge nozzle 245. When the valve 23 opens, cement falls from the discharge rack 24 and the discharge nozzle 245 into the packaging bag. When the valve 23 closes... Afterwards, the staff can drive the two sets of pressure plates 561 to move away from each other through the two sets of cylinders 562, and then turn off the electromagnet 244. At this time, under the action of the telescopic spring rod, the discharge nozzle 245 will rise and collide with the vibrating ball 242. Finally, the discharge nozzle 245 and the discharge rack 24 will vibrate, and the cement adhering to the inner wall of the discharge nozzle 245 and the discharge rack 24 will automatically fall into the packaging bag. Through the above technical solution, it is avoided that when the packaging bag is removed, the cement remaining in the discharge rack 24 will fall onto the conveying mechanism 3, thereby polluting the working environment.

[0025] like Figures 8-9 As shown, the feeding assembly 221 includes a feeding motor 2211, a support frame 2212, a transmission disc 2213, and a feeding screw 2214. The support frame 2212 is located inside the upper part of the feeding hopper 22. The support frame 2212 is provided with several sets of through holes to intercept the cement lumps in the hopper 21. The feeding motor 2211 is located on the support frame 2212. The transmission disc 2213 is located inside the support frame 2212. One end of the feeding screw 2214 is located on the transmission disc 2213, and the other end of the feeding screw 2214 is located at the end of the feeding hopper 22 near the valve 23.

[0026] like Figures 8-9As shown, the feeding assembly 221 also includes crushing blades 2215. Several sets of crushing blades 2215 are provided, and the sets of crushing blades 2215 are all mounted on the support frame 2212 and fixedly connected to the transmission disc 2213.

[0027] Workers drive the feeding screw 2214 and crushing blade 2215 to rotate by turning on the feeding motor 2211. When the feeding screw 2214 rotates, the cement in the feeding funnel 22 falls into the valve 23 and finally comes out from the discharge rack 24 and the discharge nozzle 245. By controlling the number of rotations of the feeding screw 2214, workers achieve the purpose of quantitative discharge, ensuring that the amount of cement in each packaging bag is consistent. Finally, when the crushing blade 2215 rotates, it can crush the cement lumps trapped above the support frame 2212, preventing cement lumps from falling into the packaging bags and affecting the quality of the product.

[0028] The working principle of this invention is as follows: During operation, the worker manually or via the bag feeding mechanism 6 transports the packaging bag to the bottom of the discharge rack 24. Then, the electromagnet 244 is activated to lower the discharge nozzle 245 until it enters the packaging bag. Next, two sets of cylinders 562 drive two sets of pressure plates 561 to move closer together, fixing the packaging bag to the outer wall of the discharge nozzle 245. Finally, the first rotary motor 511 is activated to drive two sets of movable dustproof plates 55 to rotate. When the two fixed dustproof plates 53 and the two movable dustproof plates 55 form a sealed working space, the valve 23, the feeding motor 2211, and the external vacuum cleaner are opened. Cement continuously falls into the packaging bag, and the dust generated during the cement's fall is sucked away by the external vacuum cleaner. When the cement in the packaging bag reaches the rated amount, the two sets of cylinders 562 first drive the two sets of pressure plates 561 to move away from each other, then the valve 23 is closed, and the feeding motor 2211 and the external vacuum cleaner are activated. Under the action of the telescopic spring rod, the discharge nozzle 245 rises and collides with the vibrating ball 242. Finally, the discharge nozzle 245 and the discharge rack 24 vibrate, and the cement adhering to the inner wall of the discharge nozzle 245 and the discharge rack 24 will automatically fall into the packaging bag, thus preventing the cement remaining in the discharge rack 24 from falling onto the conveying mechanism 3. After the packaging bag is removed from the discharge nozzle 245, the operator can drive the dust removal rod 54 to rotate through the second rotary motor 516 to remove the dust adhering to the inner walls of the two sets of fixed dustproof plates 53 and the two sets of movable dustproof plates 55. Finally, after cleaning the inner walls of the two sets of fixed dustproof plates 53 and the two sets of movable dustproof plates 55, the first rotary motor 511 drives the two sets of movable dustproof plates 55 to return to their non-working state. At this time, the conveying mechanism 3 moves the packaging bag filled with cement to the position of the sealing mechanism 4, and the sealing mechanism 4 seals the packaging bag.

[0029] Although embodiments of the present invention have been shown and described, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention without departing from the principles and spirit of the present invention.
