Description

Technical Field

[0001] The invention relates to the technical field of cement production and packaging, in particular to a cement packaging and conveying device with a dust removal function. Background Art

[0002] Cement packaging and conveying devices are mainly used for packaging and conveying cement. The main function is to transfer the produced cement into packaging bags, and then transport it to the corresponding place through the conveyor belt. The cement packaging process not only affects the quality and safety of the product, but also has an important impact on production efficiency, transportation costs and market image. At present, the equipment used in the cement packaging process is divided into fixed packaging machines and rotary packaging machines. Fixed packaging machines are widely used in cement plants due to economic and volume reasons. In order to prevent the phenomenon of dust flying during use, many dust prevention measures have appeared in cement packaging devices on the market. For example, the patent "Publication No. CN115108057A A High-efficiency Dust Removal Cement Processing Packaging Machine" discloses a dust removal method. However, in actual use, the dust removal method also has the following shortcomings, such as low working efficiency and difficulty in automatic assembly line production. In the process of cleaning the inner wall of the dust cover, the sealed space composed of three groups of dust covers will be connected to the external environment. At this time, the dust attached to the inner wall of the dust cover may escape into the external environment, thereby polluting the external environment; finally, after the work of the current cement packaging device is completed, there will be cement remaining on the inner wall of the discharge end. When the packaging bag is removed, the cement remaining on the inner wall of the discharge end often falls on the conveyor belt, thereby polluting the working environment, and the current cement packaging device has no effective treatment measures for this. Summary of the invention

[0003] The object of the present invention is to provide a cement packaging and conveying device with a dust removal function to solve the problems raised in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a cement packaging and conveying device with dust removal function, the cement packaging and conveying device comprises a mounting frame, a feeding mechanism, a conveying mechanism and a dust prevention mechanism, the feeding mechanism comprises a silo, a feeding funnel, a valve and a discharging rack, the silo is arranged on the mounting frame and is connected to the external cement production line, the feeding funnel, the valve and the discharging rack are arranged below the silo in sequence, the conveying mechanism is arranged below the mounting frame, the dust prevention mechanism comprises a fixed plate, a dust suction pipe, a fixed dust prevention plate, a dust removal rod and a movable dust prevention plate, the fixed plate is arranged near the feeding funnel One end of the valve, the dust suction pipe runs through the fixed plate and is connected to the external dust collector, the fixed dustproof plate is provided with two groups, the two groups of fixed dustproof plates are relatively arranged at the two ends of the lower part of the fixed plate, the movable dustproof plate is provided with two groups, the two groups of movable dustproof plates are relatively arranged on the outside of the two groups of fixed dustproof plates, the dust removal rod is arranged on the inner side of one group of fixed dustproof plates, a first rotating motor is arranged above the fixed plate, and a second rotating motor is arranged below the fixed plate, the first rotating motor is connected to the two groups of movable dustproof plates through a first transmission assembly, and the second rotating motor is connected to the dust collector through a second transmission assembly The two sets of fixed dust-proof plates and the two sets of movable dust-proof plates are connected with each other by rods, and the two sets of fixed dust-proof plates and the two sets of movable dust-proof plates are in contact with the conveying mechanism. When the present invention is not working, the two sets of movable dust-proof plates are located on the side where the two sets of fixed dust-proof plates are away from each other. When the present invention is working, the packaging bag is fixed to the bottom of the discharge rack, and then the first rotating motor is turned on, and the two sets of movable dust-proof plates are rotated by the first rotating motor. When the two sets of fixed dust-proof plates and the two sets of movable dust-proof plates form a closed working space, the staff can open the valve and the external dust collector, and the cement in the silo falls into the packaging bag through the valve, and the cement that escapes into the working space is removed by the external dust collector. The dust in the space is sucked away to avoid environmental pollution. After the cement is discharged, the staff can drive the dust removal rod to rotate through the second rotating motor. The dust removal rod can remove the dust attached to the inner walls of the two sets of fixed dustproof plates and the two sets of movable dustproof plates during the rotation. Compared with the dust removal operation method currently adopted by the cement packaging machine, the present invention has higher work efficiency and can be used for automated assembly line production. On the other hand, during the dust removal process, the working space of the present invention is always isolated from the external environment, thereby avoiding the phenomenon of dust overflow 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 and conveying device also includes a sealing mechanism and a bag feeding mechanism. The sealing mechanism is arranged on the side of the feeding mechanism and is located on the conveying mechanism. The bag feeding mechanism is arranged on the side of the feeding mechanism away from the sealing mechanism. The connection line between the sealing mechanism and the bag feeding mechanism is perpendicular to the connection line between the two sets of fixed dustproof plates (the functions and structures realized by the sealing mechanism and the bag feeding mechanism belong to conventional technical means in this field, and the specific working principle is not described). The staff can convey the packaging bags to the bottom of the discharging rack through manual operation or the bag feeding mechanism. When the cement packaging is completed, the packaging bags filled with cement are moved to the position of the sealing mechanism through the conveying mechanism, and the packaging bags are sealed by the sealing mechanism.

[0006] Furthermore, a bracket is provided below the fixed plate, and there are two groups of brackets. The two groups of brackets are relatively arranged on both sides of the discharging rack, and a pressure plate is provided on the side where the lower ends of the two groups of brackets are close to each other, and a cylinder is provided on the side where the lower ends of the two groups of brackets are far away from each other. Each group of pressure plates is connected to the working end of a group of cylinders, and the two groups of pressure plates are driven by the two groups of cylinders to move relative to each other. On the one hand, it is convenient to fix the packaging bag below the discharging rack 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 the escape of cement.

[0007] Furthermore, the first transmission assembly and the second transmission assembly are both arranged inside the fixed disk, the first transmission assembly includes a first internal gear and a first transmission gear, the first internal gear is meshed with the first transmission gear, the working end of the first rotating motor is connected to the first transmission gear, the two groups of movable dustproof plates are fixedly installed on the lower end of the first internal gear, the second transmission assembly includes a second transmission gear and a second internal gear, the second transmission gear is meshed with the second internal gear, the working end of the second rotating motor is connected to the second transmission gear, and the dust removal rod is fixedly installed on the lower end of the second internal gear. When working, the first rotating motor can drive the first internal gear and the two groups of movable dustproof plates to rotate through the first transmission gear, so as to facilitate the two groups of fixed dustproof plates and the two groups of movable dustproof plates to form an enclosed working space, the second rotating 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 groups of fixed dustproof plates and the two groups of movable dustproof plates. In the present invention, a sponge is wrapped on the outside of the dust removal rod, and the sponge is in a compressed state when it contacts the fixed dustproof plate, thereby preventing the sponge from being unable to contact the movable dustproof plate.

[0008] Furthermore, a feeding assembly is disposed inside the feeding funnel, and a vibration assembly is disposed inside the discharging rack. The feeding assembly has a quantitative discharging function and a crushing function, and the cement remaining on the inner wall of the discharging rack is cleaned by the vibration assembly.

[0009] Furthermore, the vibration assembly includes a fixed shaft, a vibrating ball, an electromagnet and a discharging nozzle. The lower end of the discharging frame is provided with a movable groove, and a lifting groove is provided above the movable groove. The fixed shaft is arranged in the discharging frame, the vibrating ball is arranged at the inner top of the lifting groove, the electromagnet is arranged at the inner bottom of the lifting groove, the upper end of the discharging nozzle is arranged between the vibrating ball and the electromagnet, and a fixed block is arranged outside the lower end of the discharging nozzle. The fixed block is movably installed in the movable groove through a telescopic spring rod. The fixed shaft is connected to the vibrating ball through a top rod, and the upper end of the discharging nozzle is a magnetic metal The electromagnet and the telescopic spring rod are used to control the descent and ascent of the discharge nozzle. When cement needs to be transported into the packaging bag, the electromagnet is used to extend the discharge nozzle into the packaging bag. When cement does not need to be transported into the packaging bag, the staff 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 attached 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 prevented that when the packaging bag is removed, the cement remaining in the discharge rack will not fall onto the conveying mechanism, thereby polluting the working environment.

[0010] Furthermore, the feeding assembly includes a feeding motor, a support frame, a transmission disk and a feeding screw. The support frame is arranged at the inner upper end of the feeding funnel, and a plurality of through holes are arranged on the support frame. The feeding motor is arranged on the support frame, and the transmission disk is arranged inside the support frame. One end of the feeding screw is arranged on the transmission disk, and the other end of the feeding screw is arranged at an end of the feeding funnel close to the valve. The cement agglomerated in the silo is intercepted by the plurality of through holes, and the feeding screw is driven to rotate by the feeding motor. When the feeding screw rotates, the cement in the feeding funnel will fall into the valve. By controlling the number of rotations of the feeding screw, the staff can achieve the purpose of quantitative discharging and ensure that the amount of cement in each packaging bag is consistent.

[0011] Furthermore, the feeding assembly also includes a crushing blade, and the crushing blade is provided in several groups. The several groups of crushing blades are all arranged on the support frame and fixedly connected to the transmission plate. When the feeding motor drives the feeding screw to rotate, the crushing blades rotate synchronously. On the one hand, the crushing blades can crush the agglomerated cement trapped above the support frame to prevent the agglomerated cement from falling into the packaging bag and affecting the quality of the product. On the other hand, when the crushing blades rotate, they can prevent the several groups of through holes set on the support frame from being blocked by large pieces of cement.

[0012] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: compared with the current cement packaging and conveying device, the present invention is provided with two groups of movable dust-proof plates, two groups of fixed dust-proof plates and one group of dust removal rods, and the positions of the two groups of movable dust-proof plates are controlled by a first rotating motor. When the two groups of fixed dust-proof plates and the two groups of movable dust-proof plates form a closed working space, the dust generated during cement packaging can be prevented from entering the external environment, thereby preventing the environment from being polluted. The dust removal rods can be controlled by the second rotating motor to remove the dust attached to the inner walls of the two groups of fixed dust-proof plates and the two groups of movable dust-proof plates. Compared with the dust removal operation method currently adopted by cement packaging machines, on the one hand, the work efficiency is higher and can be used for automated assembly line production. On the other hand, during the dust removal process, the present invention keeps the working space isolated from the external environment at all times. state, thereby avoiding the phenomenon of dust overflowing when cleaning the inner walls of the two groups of fixed dustproof plates and the two groups of movable dustproof plates. The present invention is also provided with a feeding component. On the one hand, the feeding component achieves the purpose of quantitative discharging and ensures that the amount of cement in each packaging bag is consistent. On the other hand, it can avoid the agglomerated cement from entering the packaging bag, thereby affecting the quality of the product. Finally, the feeding component also has a crushing function when working, thereby ensuring the quality of the cement falling into the packaging bag. Finally, the present invention is also provided with a vibration component. When the cement in the packaging bag reaches the rated amount, the staff can use the vibration component to make the cement attached to the discharge nozzle and the inner wall of the discharge rack automatically fall into the packaging bag, thereby avoiding the residual cement in the discharge rack from falling onto the conveying mechanism when the packaging bag is removed, thereby polluting the working environment.

[0018] like Figure 1-Figure 2 As shown, the cement packaging and conveying device also includes a sealing mechanism 4 and a bag feeding mechanism 6. The sealing mechanism 4 is arranged on the side of the feeding mechanism 2 and is located on the conveying mechanism 3. The bag feeding mechanism 6 is arranged on the side of the feeding mechanism 2 away from the sealing mechanism 4. The connection line between the sealing mechanism 4 and the bag feeding mechanism 6 is perpendicular to the connection line between the two groups of fixed dustproof plates 53 (the functions and structures realized by the sealing mechanism 4 and the bag feeding mechanism 6 belong to 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, and two groups of brackets 56 are provided. The two groups of brackets 56 are relatively arranged on both sides of the discharge rack 24, and a pressure plate 561 is provided on the side where the lower ends of the two groups of brackets 56 are close to each other, and a cylinder 562 is provided on the side where the lower ends of the two groups of brackets 56 are away from each other, and each group of pressure plates 561 is connected to the working end of a group of cylinders 562.

[0020] like Figure 4-Figure 6As shown, the first transmission assembly and the second transmission assembly are both arranged inside the fixed plate 51, the first transmission assembly includes a first internal gear 512 and a first transmission gear 513, the first internal gear 512 is meshed with the first transmission gear 513, the working end of the first rotating motor 511 is connected to the first transmission gear 513, two 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 is meshed with the second internal gear 515, the working end of the second rotating 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, and the outer side of the dust removal rod 54 is wrapped with sponge.

[0021] When the present invention is not working, the two groups of movable dust-proof plates 55 are located on the side where the two groups of fixed dust-proof plates 53 are away from each other. When the present invention is working, the staff can transport the packaging bags to the bottom of the discharge rack 24 through manual operation or the bag feeding mechanism 6, and then drive the two groups of pressing plates 561 to approach each other through the two groups of cylinders 562, and fix the packaging bags under the discharge rack 24 through the two groups of pressing plates 561, and then start the first rotating motor 511. The first rotating motor 511 can drive the first internal gear 512 and the two groups of movable dust-proof plates 55 to rotate through the first transmission gear 513. When the two groups of fixed dust-proof plates 53 and the two groups of movable dust-proof plates 55 form a closed working space, the staff can open the valve 23 and the external dust collector, and the cement in the silo 21 falls into the packaging bag through the valve 23, and the dust scattered into the working space is sucked away by the external dust collector to avoid environmental pollution. After the cement is discharged, the staff can drive the second internal gear 515 and the dust removal rod 54 through the second rotating motor 516. The dust removal rod 54 rotates, and the sponge wrapped on the outside of the dust removal rod 54 contacts the inner walls of the two sets of fixed dustproof plates 53 and the two sets of movable dustproof plates 55 during the rotation process, and the dust attached to the inner walls of the two sets of fixed dustproof plates 53 and the two sets of movable dustproof plates 55 is removed by the sponge wrapped on the outside of the dust removal rod 54. Compared with the dust removal operation method currently used in cement packaging machines, the present invention has higher working efficiency and can be used for automated assembly line production. On the other hand, during the dust removal process, the working space of the present invention is separated from the outside world. The environment is always in an isolated state, thereby avoiding the phenomenon of dust overflowing when cleaning the inner walls of the two groups of fixed dustproof plates 53 and the two groups of movable dustproof plates 55. Finally, after the two groups of fixed dustproof plates 53 and the two groups of movable dustproof plates 55 are cleaned, the first rotating motor 511 drives the two groups of movable dustproof plates 55 to reset to the non-working state. At this time, the packaging bag filled with cement is moved to the position of the sealing mechanism 4 through the conveying mechanism 3, and the packaging bag is sealed by the sealing mechanism 4.

[0022] like Figure 3 , Figure 7-Figure 8As shown, a feeding assembly 221 is disposed inside the feeding hopper 22, and a vibrating assembly is disposed inside the discharging rack 24.

[0023] like Figure 7 As shown, the vibration assembly includes a fixed shaft 241, a vibrating ball 242, an electromagnet 244 and a discharging nozzle 245. A movable groove is provided at the lower end of the discharging frame 24, and a lifting groove 243 is provided above the movable groove. The fixed shaft 241 is arranged in the discharging frame 24, the vibrating ball 242 is arranged at the inner top end of the lifting groove 243, the electromagnet 244 is arranged at the inner bottom end of the lifting groove 243, the upper end of the discharging nozzle 245 is arranged between the vibrating ball 242 and the electromagnet 244, and a fixed block 2451 is arranged on the outside of the lower end of the discharging nozzle 245. The fixed block 2451 is movably installed in the movable groove through a telescopic spring rod. The fixed shaft 241 is connected to the vibrating ball 242 through a top rod, and the upper end of the discharging nozzle 245 is a magnetic metal.

[0024] When the staff transports the packaging bag to the bottom of the discharge rack 24, the staff turns on the electromagnet 244, and a set of magnetic fields is generated by the electromagnet 244 to make the discharge nozzle 245 drop until the discharge nozzle 245 extends into the packaging bag. Then, the two sets of cylinders 562 drive the two sets of pressing plates 561 to approach each other, and the packaging bag and the outer wall of the discharge nozzle 245 are fixed together by the two sets of pressing plates 561. When the valve 23 is opened, cement falls from the discharge rack 24 and the discharge nozzle 245 into the packaging bag. When the valve 23 is closed, the cement falls into the packaging bag from the discharge rack 24 and the discharge nozzle 245. Afterwards, the staff can use the two groups of cylinders 562 to drive the two groups of pressure plates 561 away from each other, and then close 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 attached 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 prevented that when the packaging bag is removed, the residual cement in the discharge rack 24 will not fall onto the conveying mechanism 3, thereby polluting the working environment.

[0025] like Figure 8-Figure 9 As shown, the feeding assembly 221 includes a feeding motor 2211, a support frame 2212, a transmission disk 2213 and a feeding screw 2214. The support frame 2212 is arranged at the inner upper end of the feeding funnel 22. The support frame 2212 is provided with a plurality of through holes, and the cement agglomerated in the silo 21 is intercepted through the plurality of through holes. The feeding motor 2211 is arranged on the support frame 2212, the transmission disk 2213 is arranged inside the support frame 2212, one end of the feeding screw 2214 is arranged on the transmission disk 2213, and the other end of the feeding screw 2214 is arranged at one end of the feeding funnel 22 close to the valve 23.

[0026] like Figure 8-Figure 9As shown, the feed assembly 221 further includes crushing blades 2215 , and the crushing blades 2215 are provided in a plurality of groups. The plurality of groups of crushing blades 2215 are all provided on the support frame 2212 and fixedly connected to the transmission disc 2213 .

[0027] The staff turns on the feeding motor 2211 to drive the feeding screw 2214 and the crushing blade 2215 to rotate. When the feeding screw 2214 rotates, the cement in the feeding funnel 22 will fall into the valve 23, and finally come out from the discharging rack 24 and the discharging nozzle 245. By controlling the number of rotations of the feeding screw 2214, the staff achieves the purpose of quantitative discharging and ensures that the amount of cement in each packaging bag is consistent. Finally, when the crushing blade 2215 rotates, the crushing blade 2215 can crush the agglomerated cement trapped above the support frame 2212 to prevent the agglomerated cement from falling into the packaging bag, thereby affecting the quality of the product.

[0028] The working principle of the present invention is as follows: during operation, the staff transports the packaging bag to the bottom of the discharge rack 24 manually or through the bag feeding mechanism 6, and then turns on the electromagnet 244 to make the discharge nozzle 245 descend until the discharge nozzle 245 extends into the packaging bag, and then drives the two groups of pressing plates 561 to approach each other through the two groups of cylinders 562, and fixes the packaging bag and the outer wall of the discharge nozzle 245 together through the two groups of pressing plates 561, and finally turns on the first rotating motor 511 to drive the two groups of movable dustproof plates 55 to rotate. When the two groups of fixed dustproof plates 53 and the two groups of movable dustproof plates 55 form a closed working space, the valve 23, the feeding motor 2211 and the external vacuum cleaner are opened. At this time, the cement will continue to fall into the packaging bag, and the dust generated by the cement when falling will be sucked away by the external vacuum cleaner. When the cement in the packaging bag reaches the rated amount, the two groups of pressing plates 561 are first driven away from each other by the two groups of cylinders 562, and then the valve 23, the feeding motor 2211 and the external vacuum cleaner are closed. The material motor 2211 and the electromagnet 244, under the action of the telescopic spring rod, the discharge nozzle 245 will rise and collide with the vibrating ball 242, and finally the discharge nozzle 245 and the discharge rack 24 will vibrate, and the cement attached to the inner wall of the discharge nozzle 245 and the discharge rack 24 will automatically fall into the packaging bag, so as to prevent the residual cement in the discharge rack 24 from falling onto the conveying mechanism 3. When the packaging bag is separated from the discharge nozzle 245, the staff can drive the dust removal rod 54 to rotate through the second rotating motor 516 to remove the dust attached to the inner walls of the two groups of fixed dustproof plates 53 and the two groups of movable dustproof plates 55. Finally, after the inner walls of the two groups of fixed dustproof plates 53 and the two groups of movable dustproof plates 55 are cleaned, the two groups of movable dustproof plates 55 are driven by the first rotating motor 511 to reset to the non-working state. At this time, the packaging bag filled with cement is moved to the position of the sealing mechanism 4 through the conveying mechanism 3, and the packaging bag is sealed by the sealing mechanism 4.
