Description

Technical Field

[0001] This utility model relates to the field of conveyor belt conveying equipment technology, and specifically to a conveyor belt conveying device. Background Technology

[0002] Conveyor belts are commonly used in industry for transporting materials. Driven by a motor, they rotate in a specific direction to transport materials placed on their surface to designated locations for further processing. However, for powdery materials, some powder may remain on the conveyor belt surface during transport, affecting the conveying of subsequent materials. Therefore, it is necessary to clean up the residual material promptly.

[0003] The current method for cleaning residual materials on the conveyor belt surface is usually to scrape the surface of the conveyor belt with tools such as scrapers after the machine is stopped. This not only damages the conveyor belt, but also requires the conveyor belt to be stopped before cleaning, which seriously reduces production efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a conveyor belt conveying device to solve the technical problem that in the prior art, residual materials on the surface of the conveyor belt need to be scraped off with tools such as scrapers after the machine is stopped, which not only damages the conveyor belt but also seriously reduces production efficiency.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a conveyor belt conveying device, including:

[0007] A conveying assembly includes a fixed support and a conveyor belt rotatably mounted on the fixed support, wherein the portion of the conveyor belt that conveys powder is a conveying section, and the return portion of the conveyor belt is a return section; and

[0008] The impurity removal component includes a striking element and a driving element. The striking element is rotatably connected to the fixed bracket, and the driving element is disposed on the fixed bracket and connected to the striking element. The driving element can drive the striking element to swing back and forth to continuously impact the return section of the conveyor belt. The impurity removal component has adsorption holes for adsorbing dust.

[0009] In some embodiments, the impurity removal component includes a striking member and a driving member. The striking member is rotatably connected to the fixed bracket, and the driving member is disposed on the fixed bracket and connected to the striking member. The driving member is capable of driving the striking member to swing back and forth to continuously impact the conveyor belt.

[0010] In some embodiments, the driving element includes a drive motor and a cam. The cam is rotatably mounted on the fixed bracket and abuts against the striking element. The drive motor is mounted on the fixed bracket and connected to the cam. The drive motor can drive the cam to rotate so that the cam drives the striking element to oscillate back and forth.

[0011] In some embodiments, the striking element includes a moving plate, a rotating shaft, and an impact head. One end of the moving plate is rotatably mounted on the fixed bracket via the rotating shaft, and the impact head is located at the other end of the moving plate and faces the conveyor belt. The impact head can impact the conveyor belt when the moving plate rotates.

[0012] In some embodiments, the impact head is disposed along the width direction of the conveyor belt, and the width of the impact head is equal to the width of the conveyor belt.

[0013] In some embodiments, the impact head has a plurality of adsorption holes, the moving plate has an airflow channel, one end of the airflow channel is connected to all the adsorption holes, and the other end of the airflow channel is used to connect to a negative pressure pump.

[0014] In some embodiments, the striking element further includes an adsorption funnel disposed on the moving plate and connected to the airflow channel, with the larger end of the adsorption funnel facing the conveyor belt.

[0015] In some embodiments, the driving component is a telescopic cylinder, which has a telescopic rod and is connected to the striking component through the telescopic rod. When the telescopic rod is extended, it can drive the striking component to strike the conveyor belt.

[0018] In some embodiments, the conveyor belt conveying device further includes a vibrating element disposed on the fixed support and located between the top of the conveyor belt and the impurity removal assembly, the vibrating element abutting against the return section.

[0019] Compared with existing technologies, the conveyor belt conveying device provided by this utility model can be used to transport powdery materials. When the powder remaining on the conveyor belt returns to the impurity removal component, the component rotates and taps the conveyor belt, using inertia to drive the residual powder off the conveyor belt. Then, a negative pressure pump uses adsorption holes in the impurity removal component to adsorb and recover the dust that has detached from the conveyor belt, thus avoiding large-scale dust generation and benefiting environmental protection.

[0022] Figure 3 This is a schematic diagram of the structure of the striking component according to another embodiment of the present invention. Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] To address the technical problem in existing technologies where residual material on the conveyor belt surface needs to be scraped off with tools such as scrapers after the machine stops, which not only damages the conveyor belt but also severely reduces production efficiency, this utility model provides a conveyor belt conveying device that can remove residual powder from the conveyor belt without stopping the machine, thus not affecting work efficiency.

[0025] It should be noted that the conveyor belt conveying device described in this utility model is used for, but not limited to, conveying powder materials. For ease of explanation, this utility model only uses the application of the conveyor belt conveying device to conveying powder materials as an example. The principle of the conveyor belt conveying device applied to other types of equipment is essentially the same as that applied to conveying powder materials, and will not be described in detail here.

[0026] Please see Figure 1 , Figure 1This is a schematic diagram of the conveyor belt conveying device in one embodiment of the present invention. The conveyor belt conveying device includes a conveying component 1 and a dust removal component 2. The conveying component 1 includes a fixed support 11 and a conveyor belt 12 rotatably mounted on the fixed support 11. The conveyor belt 12 includes a conveying section 121 and a return section 122. The dust removal component 2 is rotatably mounted on the fixed support 11 and can impact the return section 122 when rotating. The dust removal component 2 has adsorption holes for adsorbing dust.

[0027] In this embodiment, the fixed bracket 11 mainly serves a supporting function, supporting the various components mounted on it. The conveyor belt 12 rotates relative to the fixed bracket 11 under the drive of the corresponding motor to transport the powder placed in the conveying section 121 from a lower position to a higher position, so that the powder can enter the next process for processing. The conveyor belt 12 rotates cyclically during operation. The part of the conveyor belt 12 that contacts and transports the powder is the conveying section 121, and the part at the bottom of the conveyor belt 12 that does not transport powder and returns from the end of the feeding process to the beginning of the feeding process is the return section 122. It can be understood that the conveying section 121 and the return section 122 of the conveyor belt 12 are constantly changing during the cyclic rotation process. After conveying the powder to the top of the conveyor belt 12, the section of the conveyor belt 12 with residual powder becomes the return section 122, which enters below the conveyor belt 12. After being impacted by the impurity removal component 2, the powder adhering to the return section 122 can be separated from the conveyor belt 12 by inertia. The adsorption holes of the impurity removal component 2 are connected to a negative pressure pump to create a vacuum in the adsorption holes, thus adsorbing the dust separated from the conveyor belt 12. This avoids significant dust generation after the powder separates from the conveyor belt 12, which is beneficial to environmental protection. The conveyor belt 12 does not need to be stopped. While conveying the powder, the impurity removal component 2 can continuously impact the opposite side of the conveyor belt 12 to remove the powder accumulated on the conveyor belt 12, without affecting work efficiency. Small protrusions 123 can be provided on the surface of the conveyor belt 12. These protrusions 123 can limit the powder or increase the friction with the powder pile, so as to stably convey the powder to a higher position.

[0028] In one embodiment, please refer to Figure 1 The impurity removal component 2 includes an impactor 21 and a drive component 22. The impactor 21 is rotatably connected to a fixed bracket 11, and the drive component 22 is disposed on the fixed bracket 11 and connected to the impactor 21. The drive component 22 can drive the impactor 21 to swing back and forth to continuously impact the conveyor belt 12. In this embodiment, when energized, the drive component 22 can drive the impactor 21 to swing back and forth continuously to impact the conveyor belt 12, removing the powder accumulated on the conveyor belt 12. In this embodiment, the drive component 22 automatically controls the impactor 21 to frequently impact the conveyor belt 12. Compared with the method of manually driving the impactor 21, this embodiment uses automatic control, which is convenient and labor-saving.

[0029] In one embodiment, please refer to Figure 1 The driving component 22 includes a drive motor 221 and a cam 222. The cam 222 is rotatably mounted on the fixed bracket 11 and abuts against the striking component 21. The drive motor 221 is mounted on the fixed bracket 11 and connected to the cam 222. The drive motor 221 can drive the cam 222 to rotate, so that the cam 222 drives the striking component 21 to oscillate back and forth. In this embodiment, when the drive motor 221 is energized, it can drive the cam 222 to rotate continuously. When the cam 222 rotates, it can drive the striking component 21 to oscillate back and forth cyclically, so that the striking component 21 frequently impacts the conveyor belt 12, thereby achieving the purpose of cleaning the powder. In this embodiment, the method of driving the striking component 21 to move through the cam 222 is relatively simple, with a concise structure and small space occupation. In other embodiments, the driving component 22 can also be a telescopic cylinder, which is connected to the striking component 21 and drives the striking component 21 to move back and forth to impact the conveyor belt 12 through telescopic movement.

[0030] In one embodiment, please refer to Figure 2 The striking element 21 includes a moving plate 211, a rotating shaft 212, and an impact head 213. One end of the moving plate 211 is rotatably mounted on a fixed bracket 11 via the rotating shaft 212. The impact head 213 is located at the other end of the moving plate 211 and faces the return section 122 of the conveyor belt 12. The impact head 213 can impact the conveyor belt 12 when the moving plate 211 rotates. In this embodiment, the impact head 213 protrudes from the surface of the moving plate 211. When the moving plate 211 rotates, it can drive the impact head 213 to move, so that the impact head 213 impacts the conveyor belt 12. The impact head 213 is located near the end of the moving plate 211, and the center of gravity of the striking element 21 is concentrated on the impact head 213, so that the impact head 213 has a greater force when impacting the conveyor belt 12, which can give the conveyor belt 12 a greater inertial effect and effectively separate the residual powder on the conveyor belt 12.

[0031] In one embodiment, please refer to Figure 2 The impact head 213 is arranged along the width direction of the conveyor belt 12, and the width of the impact head 213 is equal to the width of the conveyor belt 12. In this embodiment, the width of the impact head 213 is equal to the width of the conveyor belt 12. When the impact head 213 impacts the conveyor belt 12, it can maintain a large force application area on the conveyor belt 12. The force covers the transverse part of the conveyor belt 12, which can effectively remove the powder accumulated on the conveyor belt 12.

[0032] In one embodiment, please refer to Figure 2The impact head 213 has multiple adsorption holes 214, and the moving plate 211 has an airflow channel 215. One end of the airflow channel 215 connects to all the adsorption holes 214, and the other end of the airflow channel 215 is used to connect to a negative pressure pump. In this embodiment, the impact head 213 has multiple adsorption holes 214. When the negative pressure pump is working, it can drive all the adsorption holes 214 to form a negative pressure through the airflow channel 215. While impacting the conveyor belt 12, the impact head 213 can absorb the powder separated from the conveyor belt 12 in the first instance, which can avoid dust generation when impacting the conveyor belt 12 and can also collect residual powder in a timely manner. Multiple adsorption holes 214 can absorb powder at the same time, which can improve the absorption efficiency and reduce dust.

[0033] In one embodiment, please refer to Figure 3 The striking element 21 also includes an adsorption funnel 216, which is disposed on the moving plate 211 and connected to the airflow channel 215. The larger end of the adsorption funnel 216 faces the conveyor belt 12. In this embodiment, the adsorption funnel 216 is used to assist in the adsorption of powder. The opening area of ​​the adsorption funnel 216 is much larger than that of the adsorption hole 214, resulting in high efficiency in powder absorption. It can absorb powder that has not been absorbed by the adsorption hole 214, thereby further improving the powder absorption effect.

[0034] In one embodiment, please refer to Figure 1 The conveyor belt conveying device also includes a first collection box 3 located below the return section 122. The first collection box 3 is used to collect powder falling from the return section 122. In this embodiment, by providing the first collection box 3 below the conveyor belt 12, it is possible to receive powder that has separated from the conveyor belt 12 and has not been absorbed by the adsorption holes 214, so as to further collect residual powder separated from the conveyor belt 12. The length of the first collection box 3 substantially covers the conveyor belt 12 to facilitate the full reception of powder separated from the conveyor belt 12.

[0035] In one embodiment, please refer to Figure 1 The conveyor belt conveying device also includes a second collection box 4, which is connected to the bottom of the conveyor belt 12 and is used to collect powder that slides down from the conveyor section 121. Besides adhering to the conveyor belt 12, some powder may accumulate in the conveyor section 121 of the conveyor belt 12 and slide to the bottom of the conveyor belt 12 under its own gravity. The second collection box 4 can receive the powder that slides to the bottom of the conveyor belt 12, thereby further improving the powder collection efficiency. The powder collected by the first collection box 3, the second collection box 4, the adsorption hole 214, and the adsorption funnel 216 can be centrally sent to the raw material pool for reuse, saving raw materials.

[0036] In one embodiment, please refer to Figure 1The conveyor belt conveying device also includes a vibrating element 5, which is disposed on the fixed support 11 and located between the top of the conveyor belt 12 and the impurity removal component 2. The vibrating element 5 abuts against the return section 122. In this embodiment, the vibrating element 5 can be driven by piezoelectric ceramic to vibrate at high frequency, so as to loosen the powder attached to the conveyor belt 12 before the impacting element 21 impacts the conveyor belt 12. Subsequently, the powder attached to the conveyor belt 12 is more easily separated by the impacting element 21, which can improve the powder separation effect.

[0037] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail below:

[0038] The conveyor belt 12 provided by this utility model can be used to transport powdery materials. When the powder remaining on the conveyor belt 12 returns to the impactor 21, the impactor 21, driven by the drive member 22, can rotate and impact the conveyor belt 12, thereby driving the residual powder off the conveyor belt 12 through inertia. At this time, a negative pressure pump is used to absorb and recover the dust that has detached from the conveyor belt 12 through the adsorption holes 214 opened in the impactor 21, which can avoid large-scale dust pollution and is beneficial to environmental protection. It can be seen that the conveyor belt 12 of this utility model can absorb residual powder while working without stopping the machine, without affecting production efficiency.

[0039] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
