Description

Technical Field

[0001] This utility model relates to the technical field of dry-mixed mortar production and processing equipment, and in particular to a conveying device for bagged dry-mixed mortar. Background Technology

[0002] Dry-mixed mortar, a widely used material in construction engineering, is typically pre-mixed, metered, and packaged in bags at the factory before being transported to the construction site. In automated production processes, conveyor belts are key equipment for transferring bagged mortar from the packaging station to downstream stations (such as stacking and warehousing).

[0003] During the filling and sealing of mortar, due to the powdery nature of the material and the flexible material of the packaging bags, a large amount of dust inevitably adheres to the outer surface of the bags. If this dust is not cleaned up in a timely and effective manner, it will escape into the air during subsequent transportation and handling, not only seriously polluting the working environment and endangering the health of operators, but also making it difficult to perform coding, labeling, or final neat stacking of the packaging bags with a large amount of dust.

[0004] To address this, some existing technologies attempt to add dust removal steps to the conveyor line, such as using brushes or blowers. However, the surface of freshly filled bagged mortar is not smooth; it is bulging, soft, and covered with numerous wrinkles and pits. These irregular wrinkles and pits create "dead zones" where dust can hide. Conventional cleaning or blowing methods can only reach the raised surface of the packaging bag and cannot penetrate into these wrinkles, resulting in incomplete dust removal and a significant reduction in dust removal effectiveness.

[0005] Therefore, this utility model proposes a conveying device for bagged dry-mixed mortar to overcome the shortcomings of the prior art. Utility Model Content

[0006] To overcome the above deficiencies, this utility model provides a conveying device for bagged dry-mixed mortar, which aims to improve the existing technology where the surface of the bagged dry-mixed mortar is bulging, wrinkled, and uneven, making it difficult to effectively and thoroughly remove the attached dust, causing environmental pollution and affecting subsequent automated processes.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a conveying device for bagged dry-mixed mortar, comprising: a frame and a conveyor belt installed inside the frame, and further comprising a pressing component and a dust removal component, wherein the pressing component and the dust removal component are both fixedly connected to the top of the frame and are arranged sequentially along the conveying direction of the conveyor belt; The pressing assembly includes a support frame, a sliding block is slidably connected inside the support frame, a groove is opened inside the support frame for the sliding block to slide, a cylinder is also fixedly connected inside the support frame, the output end of the cylinder drives the sliding block to slide along the groove, a rotating rod is rotatably connected inside the sliding block, a pressure roller is fixedly connected on the rotating rod, and the pressure roller is located above the conveyor belt; The dust removal assembly includes a dust collection box, a dust collection pipe connected to the top of the dust collection box, a fixed frame fixedly connected inside the dust collection box, and a brush plate connected to the bottom of the fixed frame.

[0008] Preferably, it further includes a guide assembly, which is fixedly connected to the top of the frame and located upstream of the pressing assembly along the conveying direction of the conveyor belt.

[0021] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0022] Reference Figures 1-5 This utility model provides a conveying device for bagged dry-mixed mortar, which aims to solve the problem in the prior art that dust is difficult to be effectively and thoroughly removed due to the uneven surface wrinkles of bagged materials.

[0023] Specifically, it includes a frame 1 and a conveyor belt 2 installed inside the frame 1. The frame 1 serves as the mounting base and overall support structure for the entire device, while the conveyor belt 2 is used to carry and transport bagged dry-mixed mortar.

[0024] It also includes a pressing component 4 and a dust removal component 5. Both the pressing component 4 and the dust removal component 5 are fixedly connected to the top of the frame 1 and are arranged sequentially along the conveying direction of the conveyor belt 2. Through the structural cooperation of pressing first and then removing dust, the surface of the bagged mortar is thoroughly cleaned.

[0025] The pressing assembly 4 includes a support frame 401, with a sliding block 405 slidably connected inside the support frame 401. A groove 404 is provided inside the support frame 401 for the sliding block 405 to slide. A cylinder 406 is also fixedly connected inside the support frame 401. The output end of the cylinder 406 drives the sliding block 405 to slide up and down along the groove 404. A rotating rod 403 is rotatably connected inside the sliding block 405. A pressure roller 402 is fixedly connected to the rotating rod 403. The pressure roller 402 is positioned above the conveyor belt 2 through this connection method. The action of the cylinder 406 can drive the pressure roller 402 to rise and fall to adapt to bagged mortar of different thicknesses and apply pressure.

[0026] The dust removal assembly 5 includes a dust collection box 501. A dust collection pipe 502 is connected to the top of the dust collection box 501 for discharging the collected dust outward. A fixing frame 503 is fixedly connected inside the dust collection box 501. A brush plate 504 is connected to the bottom of the fixing frame 503. The brush plate 504 is positioned directly opposite the surface of the bagged mortar after it has been flattened by the pressure roller 402, and is used to perform preliminary physical cleaning on the flattened surface.

[0027] To position and organize the incoming bagged mortar before flattening, the device also includes a guide assembly 3. The guide assembly 3 is fixedly connected to the top of the frame 1 and is located upstream of the pressing assembly 4 along the conveying direction of the conveyor belt 2. That is, the bagged mortar first passes through the guide assembly 3 and then enters the pressing assembly 4, ensuring that the mortar bags can enter the flattening process in the correct position and posture, thus guaranteeing the subsequent flattening and dust removal effects. The guide assembly 3 includes a material sorting plate 301, a fixing block 302, a threaded rod 303, and a rotating block 304. The fixing block 302 is fixed to the top of the frame 1 by welding or bolts, etc. The threaded rod 303 is threaded into the fixing block 302. The material sorting plate 301 is set perpendicular to the conveying direction of the conveyor belt 2, and the lower end face of the material sorting plate 301 is flush with the conveyor belt. The upper surface of 2 has a safety gap. One end of the material guide plate 301 is fixedly connected to the end of the threaded rod 303 away from the rotating block 304. The rotating block 304 is fixedly connected to the outer wall of the threaded rod 303 and serves as a manually operated part. By manually turning the rotating block 304, the threaded rod 303 can be moved within the fixed block 302 using the threaded pair transmission principle, thereby driving the material guide plate 301 to move in the width direction of the conveyor belt 2 to adjust the guide width. In order to limit the movement on both sides of the conveyor belt 2, two sets of guide components 3 are symmetrically arranged and located on both sides of the conveyor belt 2. The two sets of guide components 3 have the same structure. By adjusting the distance between the material guide plates 301 on both sides, different sizes and specifications of bagged mortar can be accommodated to ensure that it moves stably on the center line of the conveyor belt 2.

[0028] The axis of the rotating rod 403 is perpendicular to the conveying direction of the conveyor belt 2. The outer circumferential surface of the pressure roller 402 is a smooth cylindrical surface, which is used to roll the bagged mortar located on the conveyor belt 2. When the cylinder 406 drives the sliding block 405 to move towards the conveyor belt 2, the pressure roller 402 descends and presses the surface of the bagged mortar with its own weight or the additional pressure provided by the cylinder 406. As the conveyor belt 2 moves, the bagged mortar passes under the pressure roller 402. The pressure roller 402 is passively rotated under the drive of the bagged mortar, forcibly flattening the original bulging area and wrinkles on the surface of the bagged mortar to form a flat and taut surface.

[0029] To achieve active dust collection, a dust collection fan is also installed inside the dust collection box 501. The dust collection fan can be a centrifugal fan or an axial fan. The air inlet of the dust collection fan is connected to the internal space of the dust collection box 501, and its air outlet is connected to the dust collection pipe 502. When the dust collection fan is working, a negative pressure is formed inside the dust collection box 501, which strongly sucks up the dust swept down by the brush plate 504 and the fine dust attached to the surface of the bagged mortar. The dust is then transported to the external central dust collection system for unified treatment through the dust collection pipe 502. In order to enhance the initial cleaning effect, the brush plate 504 is preferably located on the side of the dust collection box 501 near the feed inlet, and the bristles of the brush plate 504 face the surface of the conveyor belt 2. The length of the bristles is set so that the ends can elastically contact the surface of the flattened bagged mortar without generating too much resistance to affect the conveying.

[0030] A baffle 6 is fixedly installed at the end of the conveyor belt 2. The height of the baffle 6 is higher than the height of the bagged mortar. It is used to block the bagged mortar being conveyed to the end, causing it to pause at a designated position and wait for subsequent processing. To achieve automation of end-point gripping, the device further includes a robotic arm 7 and sensors. The robotic arm 7 is a multi-joint robot. Its base is installed on an independent ground or platform next to the frame 1 to avoid vibration interference to the conveying device when it moves. The sensor can be a photoelectric sensor or a proximity switch. It is installed in the vicinity of the baffle 6 to detect whether bagged mortar has arrived and been blocked by the baffle 6. Once the sensor detects a signal, it will trigger the robotic arm 7 to start according to the preset program and perform a series of actions such as gripping, rotating, and placing, so as to transport the cleaned bagged mortar from the end of the conveyor belt 2 to the designated stacking area.

[0031] Working principle: During operation, the frame 1 serves as the support point for the device, and a conveyor belt 2 is installed inside it. The mortar is bagged and sealed at the bagging machine and moves along the bagging and unloading line to the conveyor belt 2. The conveyor belt 2 transports the bagged mortar. The bagged mortar is first guided by the guide component 3 set on the frame 1 to limit and straighten the bagged mortar, and then it is flattened by the pressing component 4 to make its surface flat, so that the dust removal component 5 on the side can contact all dust without dead angles. The bagged mortar passing through the dust removal component 5 is temporarily held at one end of the conveyor belt 2 and blocked by the baffle 6 at the end of the conveyor belt 2. The sensor installed on the frame 1 detects the incoming material, and then the robotic arm 7 set on the outer wall of the frame 1 moves to the set position to grab the material and then moves the bagged mortar to the set stacking area for storage.

[0032] When guiding the bagged mortar, the rotating block 304 is turned to drive the threaded rod 303 fixed on the outer wall to rotate inside the fixing block 302. The fixing block 302 is fixed to the top of the frame 1. By moving the threaded rod 303, the material guide plate 301 set at one end of the threaded rod 303 can be moved on the surface of the conveyor belt 2. The guide plate 301 of the bagged mortar limits and straightens the bagged mortar. By adjusting the position of the material guide plate 301, it can be adapted to bagged mortar of different sizes.

[0033] When pressing bagged mortar, the bagged mortar is guided and conveyed by the guide assembly 3 and passes under the pressure roller 402 inside the support frame 401. The support frame 401 is fixed to the top of the machine frame 1. A rotating rod 403 is fixedly connected inside the pressure roller 402. The rotating rod 403 is rotatably connected inside the sliding block 405. The sliding block 405 is located inside the support frame 401. When it is necessary to adjust the position of the pressure roller 402, the output end of the cylinder 406 fixed inside the support frame 401 drives the sliding block. 405 slides inside the support frame 401. The sliding of the sliding block 405 drives the internal rotation of the rotating rod 403 to slide along the groove 404 opened inside the support frame 401, so as to adapt to bagged mortar of different volumes. The surface of the mortar bag after it has not been pressed is bulging, full of wrinkles and pits. Dust will hide in these dead corners. The pressure roller 402 forcibly flattens and tightens the surface of the bag. A flat bagged mortar surface can allow the dust removal component 5 to contact all dust without dead corners.

[0034] When removing dust from bagged mortar, the bagged mortar is compressed and then enters the dust collection box 501 fixed on the top of the frame 1 via the conveyor belt 2. The dust collection box 501 is fixedly connected to the fixing frame 503, and the bottom of the fixing frame 503 is equipped with a brush plate 504. The bagged mortar first passes through the brush plate 504 to clean the dust remaining on its surface. Then, the dust removal fan installed in the dust collection box 501 sucks away the dust on the bagged mortar and extracts it for storage through the dust collection pipe 502 set at the top of the dust collection box 501, which reduces dust pollution and is beneficial to protecting the environment and human health.
