Description

Technical Field

[0001] This application relates to the field of building material conveying technology, and in particular to a pipe fitting conveying device. Background Technology

[0002] A large amount of building materials are used during construction, and pipe fittings are among the most frequently used. To facilitate the transportation of pipe fittings, conveyor belts are typically used for the continuous and efficient transport of large quantities of pipe fittings.

[0003] During storage, pipe fittings are susceptible to rust due to factors such as moisture in the air. After the pipe fittings are transported to the designated location, the rust must be removed from the surface before they can be used to prevent further corrosion and thus extend their service life.

[0004] Currently, the design of pipe conveying devices is relatively simple, only capable of conveying pipes. During the conveying process, rust on the surface of the pipes cannot be removed at the same time, resulting in rust still remaining on the surface of the pipes after conveying. This means that rust removal equipment is still needed to remove the rust from the surface of the pipes after conveying, which increases the workload and time cost, and affects the appearance and service life of the pipes.

[0005] Therefore, the present invention proposes a pipe fitting conveying device to solve the above-mentioned problems. Summary of the Invention

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0023] This application provides a pipe fitting conveying device to solve the problem in related technologies where it is difficult to remove rust from the surface of pipe fittings during transportation.

[0024] Please see Figures 1 to 20 A pipe fitting conveying device, comprising: The conveyor frame 1 is equipped with multiple drive rollers, each of which has sprockets at both ends; one of the drive rollers is connected to a servo motor. Two annular conveyor chains 2 are respectively connected to sprockets at both ends of multiple transmission rollers; multiple bearing plates 3 are provided on the outer ring of the annular conveyor chains 2 along their annular trajectory direction; a pipe fitting processing mechanism 4 is provided on each bearing plate 3; the pipe fitting processing mechanism 4 has a working space for accommodating pipe fittings, and a rust removal device is provided in the working space. The rack and pinion assembly is installed on top of the conveyor frame 1. During the movement of multiple pipe fitting processing mechanisms 4 driven by the annular conveyor chain 2, the rack and pinion assembly is connected to the multiple pipe fitting processing mechanisms 4 located above, so as to drive the rust removal device inside the pipe fitting processing mechanism 4 connected to the rack and pinion assembly to work.

[0025] During the movement of multiple pipe fitting processing mechanisms 4 driven by the annular conveyor chain 2, the rack assembly is connected to the multiple pipe fitting processing mechanisms 4 located above, so as to drive the rust removal device inside the pipe fitting processing mechanism 4 connected to the rack assembly to work to remove rust from the surface of the pipe fittings. At the same time, no additional drive source is required, simplifying the structure.

[0026] In addition, during the transportation of multiple pipe fittings by the multiple pipe fitting processing mechanism 4, multiple pipe fittings can be transported separately and isolated at the same time, thereby avoiding damage caused by collisions between pipe fittings; the rust removal operation is only performed when the pipe fitting processing mechanism 4 runs to the upper side of the annular conveyor chain 2; when it runs to the upper side of the annular conveyor chain 2, the rust removal device does not work, and the pipe fittings fall from the working space to the next transport line.

[0027] In some preferred embodiments, refer to the appendix Figures 1 to 7 The internal structure of the pipe fitting processing mechanism 4 is as follows: Pipe fitting processing mechanism 4 includes a box structure 41, which has a working space inside; The rust removal device includes a first rust removal component 42 and a second rust removal component 43 for removing rust from the outer wall of the pipe fittings; the first rust removal component 42 and the second rust removal component 43 have the same structure and are arranged in parallel; the first rust removal component 42 includes a cylinder 421, the two ends of which are rotatably connected to the inner wall of the box structure 41; a wire brush sleeve 422 is provided on the outer side of the cylinder 421, and a rotating shaft 424 passing through the box structure 41 is provided at one end of the cylinder 421, and a gear 425 is provided on the rotating shaft 424; the rack assembly includes a rack 5, which is used to mesh with the gear 425.

[0028] refer to Figure 8 As shown, the box structure 41 includes a processing box 411 detachably mounted on the support plate 3. A dust cover 412 is hinged to the top opening of the processing box 411. The dust cover 412 is provided with a discharge port 413. A rotating shaft is rotatably mounted on the inner wall of the discharge port 413. A baffle plate 414 and a baffle plate 415 are fixedly mounted on both sides of the outer wall of the rotating shaft. The baffle plate 414 and the baffle plate 415 have semi-circular grooves for placing pipe fittings.

[0029] Multiple pipe processing mechanisms 4 rotate clockwise. Rack 1 5 and rack 2 6 are fixedly mounted on the top of the conveyor frame 1. Rack 2 6 is parallel to rack 1 5 and is equal to two-thirds of the length of the top of the conveyor frame 1. Rack 1 5 and the conveyor frame 1 are of equal length. During the meshing connection between gear 1 425 and rack 1 5, the wire brush sleeve 422 is driven to rotate by the driving force input by gear 1 425, thus rotating relative to the pipe. Under continuous friction, the rust powder separates from the outer wall of the pipe. At the same time, rack 2 6 and gear 1 425 mesh, and gear 2 4268 is driven by the rotational force generated by the drive. Under the acceleration of the gearbox 4266, the rotational speed of the fan blade 4267 is increased. The suction force generated can suck the dust from the grinding into the rust powder collection cylinder 4262 for storage. The pipe fitting processing mechanism 4 includes a box structure 41 detachably mounted on top of the support plate 3. Inside the box structure 41, on the left and right sides, are respectively provided a rust removal component 42 and a rust removal component 43 for cooperating to complete the rust removal work on the outer wall of the pipe fitting. A storage tank 44 for supplying rust-preventive liquid to the rust removal components 42 and 43 is fixedly mounted on the outer wall of the box structure 41. An injection pipe is fixedly mounted on the outer wall of the storage tank 44, and a one-way valve 3 is fixedly mounted inside the injection pipe, allowing only the rust-preventive liquid to flow in. This one-way valve 3 ensures that the rust-preventive liquid inside the storage tank 44 will not overflow under various conditions. The housing structure 41 includes a processing box 411 detachably mounted on top of the support plate 3 by bolts, a dust cover 412 hinged to the top of the processing box 411, and a discharge port 413 opened on the top of the processing box 411. A rotating shaft is rotatably mounted on the inner wall of the discharge port 413, and baffle plate 414 and baffle plate 415 are fixedly mounted on both sides of the outer wall of the rotating shaft, respectively. The width formed by baffle plate 414, baffle plate 415 and the rotating shaft is adapted to the width of the discharge port 413, so that the discharge port 413 is just covered without affecting the rotation, and preventing rust from being scattered to the outside. Baffle plate 1 (414) and baffle plate 2 (415) can remain horizontal when not subjected to external force. However, if a pipe is placed on top of either baffle plate 1 (414) or baffle plate 2 (415), gravity will cause either baffle plate 1 (414) or baffle plate 2 (415) to flip over, and the steel pipe will fall between rust removal component 1 (42) and rust removal component 2 (43). The length of the pipe is less than or equal to the length of baffle plate 1 (414) or baffle plate 2 (415).

The plurality of arc-shaped protrusions 72 are distributed at intervals along a designed straight line.

[0036] A material conveying method of a material conveying device, the method comprising the following steps: Step 1, Pre-processing preparation: Place the pipe fitting in the box structure 41, with the pipe fitting located between the first rust removal component 42 and the second rust removal component 43; the specific process is as follows: place the pipe fitting on top of either the first baffle plate 414 or the second baffle plate 415. Since the first baffle plate 414 and the second baffle plate 415 are symmetrically arranged on both sides of the rotating shaft, when the pipe fitting is placed on top of either the first baffle plate 414 or the second baffle plate 415, the balance between the first baffle plate 414 and the second baffle plate 415 is broken, and the side on which the pipe fitting is placed rotates and flips around the rotating shaft, so the pipe fitting can fall between the tops of the first rust removal component 42 and the second rust removal component 43 inside the processing box 411.

[0037] Step 2, Pipe Rust Removal: A servo motor drives one of the transmission rollers to rotate. Since the sprocket is fixed on the transmission roller, the annular conveyor chain drives multiple pipe processing mechanisms 4 to rotate synchronously clockwise at a uniform speed. The rust on the outer wall of the pipe fitting is ground off, and the granular rust powder is collected. The specific process is as follows: The pipe fitting is located in the gap between rust removal component 1 42 and rust removal component 2 43, with the outer wall of the pipe fitting in contact with the wire brush sleeve 422. At this time, the servo motor is activated to drive one of the transmission rollers to rotate. Simultaneously, the sprocket fixed on the outer wall of the transmission roller drives the annular conveyor chain to rotate. Therefore, the pipe fitting processing mechanism 4, connected to the bearing plate 3 and the annular conveyor chain, can move synchronously. When the pipe fitting processing mechanism 4 is located at the top leftmost position of the conveyor frame 1, gear 1 425 and rack 1 5 are meshed, and gear 2 4268 and rack 2 6 are meshed. Therefore, when the pipe fitting processing mechanism 4 moves relative to the conveyor frame 1, rack 1 5 and rack 2 6 drive gear 1 425 and gear 2 4268 to rotate. During the rotation of the wire brush sleeves 422 on both sides, the rust powder is ground off the outer wall of the pipe fitting. The rust on the wall is polished, and the rust powder is separated from the pipe wall and dispersed in the treatment box 411. At the same time, rack 26 drives gear 2 4268 to rotate, and after being accelerated by gearbox 4266, fan blade 4267 rotates rapidly. The air inside the rust powder collection cylinder 4262 is extracted and discharged through the through hole on the outer wall of the rust powder collection cylinder 4262 near gear 2 4268. Therefore, negative pressure can be generated inside the mounting bracket 4261. Since the rotating shaft 424 is sealed and rotated in the connecting hole 4264, the inside of the cylinder 421 is subjected to the suction of fan blade 4267. The scattered rust powder enters the cylinder 421 through the collection port 423 and is sucked into the rust powder collection cylinder 4262 through the rotating shaft 424. The rust powder is filtered by filter plate 4265, and the air is discharged through the filter hole.

[0038] Step 3, Pipe Protection: After the rust removal components 1 42, rust removal component 2 43 and rack 2 6 are separated, they immediately meet and are driven by the pumping control component 7. The rack 1 5 continues to mesh with the rust removal components 1 42 and rust removal component 2 43. The rust removal components 1 42 and rust removal component 2 43 intermittently spray rust-preventive liquid. During the pipe rotation process, the rust-preventive liquid is evenly sprayed on the surface of the pipe. The specific process is as follows: After gear 2 4268 and rack 2 6 separate, gear 1 425 continues to mesh with rack 1 5, and the pipe continues to rotate. At this time, piston rod 4287 intermittently meets arc-shaped protrusion 72 and moves towards the inside of suction cylinder 4281 under the push of arc-shaped protrusion 72. The rust inhibitor inside suction cylinder 4281 is squeezed out by the moving piston 4286. Due to the setting of check valve 2 4285 and check valve 1 4283, the rust inhibitor can only be discharged through connecting pipe 4284. After piston rod 4287 and arc-shaped protrusion 72 separate, spring 2 4288 pushes piston rod 4287 away from suction cylinder 4281. The rust inhibitor in storage tank 44 enters the cavity of suction cylinder 4281 through inlet pipe 4282. Since the delivery pipe 4271 and the connecting pipe 4284 are sealed and rotatably connected, the rust inhibitor enters multiple annular pipes 4272 through the delivery pipe 4271. The rust inhibitor enters the delivery pipe 4271 and pushes the baffle 42735 to slide along the inner wall of the pipe body 42731 in a sealed manner until the baffle 42735 slides above the spray hole 42732. At this time, the spray hole 42732 moves upward synchronously under the push of the lifting rod 42733 until the dust cover 42734 moves above the spray hole 42732. The rust inhibitor is sprayed out through the spray hole 42732 and evenly sprayed on the outer wall of the pipe. After the piston rod 4287 and the arc-shaped protrusion 72 separate, the pressure of the rust inhibitor inside the pipe body 42731 is insufficient to push the baffle 42735 to move. The spring 42736 pushes the baffle 42735 downward with elastic force, and the dust cover 42734 covers the spray hole 42732.

[0039] Step 4: Release the pipe fitting: When the pipe fitting processing mechanism 4 moves to the far right of the conveyor frame 1 and continues to move, the top opening of the box structure 41 opens under its own gravity, and the pipe fitting automatically falls out of the pipe fitting processing mechanism 4. The specific process is as follows: When the processing box 411 moves to the far right of the conveyor frame 1 and continues to move, it flips over. The dust cover 412 and the processing box 411 are connected by a hinge, so they open automatically under gravity, and the pipe fitting falls out of the processing box 411 under its own gravity.

[0040] Beneficial effects of this invention: (1) By setting up multiple pipe fitting processing mechanisms, multiple pipe fittings can be transported separately and isolated at the same time, thereby avoiding damage caused by collision between pipe fittings; secondly, during the transport process, the rust on the outer wall of the pipe fitting can be removed by the rust removal components 1 and 2, so that the surface of the pipe fitting remains clean and the pipe fitting can be prevented from rusting faster. When the pipe fitting is used later, there is no need to perform rust removal operation, thereby saving the time of rust removal; furthermore, by setting up a rust powder collection component, the suction force generated by the fan blades can draw the rust powder off the pipe fitting into the rust powder collection cylinder for centralized storage while the pipe fitting is being rusted, thereby preventing the rust powder from flying around and achieving the purpose of preventing pollution of the surrounding air.

[0041] (2) During the movement of the wire brush sleeve and rust powder collection assembly, rack one and rack two can synchronously drive gear one and gear two to rotate. Rack one drives gear one to rotate, which can provide power for the rotation of the wire brush sleeve and achieve the effect of removing rust from the outer wall of the pipe fitting; while rack two drives gear two to rotate, which can provide driving force for the rotation of the fan blade and achieve the effect of sucking up the rust powder that has been polished. Secondly, the operation of the wire brush sleeve and rust powder collection assembly does not require a separate drive device, thus saving the cost of setting up a drive device, making the structure simpler and facilitating subsequent inspection and maintenance.

[0042] (3) By setting up a rust-preventive liquid spraying component, a pumping component, and a pumping control component, the piston rod can be intermittently pushed by the arc-shaped drive block on the side plate component during the conveying of the pipe fitting, thereby achieving the purpose of the piston sucking up or squeezing out the rust-preventive liquid, providing driving force for the spraying of the rust-preventive liquid; secondly, by setting up multiple nozzle units, the rust-preventive liquid spraying component can evenly spray the rust-preventive liquid onto the surface of the pipe fitting during the pipe fitting flipping process, forming a protective layer on the surface of the pipe fitting, which plays a role in protecting the pipe fitting; furthermore, in the nozzle unit, through the design of the dust cover, the spray hole can be kept open during the spraying of the rust-preventive liquid, and when the rust-preventive liquid is not sprayed, the dust cover can block the spray hole to prevent dust from entering, thereby achieving a good anti-clogging effect.

[0043] (4) The rust powder collection component and the mounting bracket are designed separately, so that the rust powder collection cylinder can be disassembled from the mounting bracket after the pipe is transported, and the rust powder can be removed from the rust powder collection cylinder more conveniently for the next use.
