DETAILED DESCRIPTION

[0035] In order to make the technical personnel in the technical field to which the present application belongs to understand the present application more clearly, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0036] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0037] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0038] The embodiment of the present invention discloses a hot air recovery cloth sealing plate vibration device, which can solve the technical problem of smoke hood pressure exceeding the limit value caused by the cloth sealing plate adhesive in the prior art, thereby avoiding system shutdown failures caused by this, improving the continuity and stability of the production line, and preventing personnel from being in a high-temperature working environment for a long time, reducing the danger to personnel, improving working safety, and improving product quality and production efficiency.

[0039] The technical solution of the present application is described in detail below through specific embodiments:

[0040] See also Figure 1 and Figure 4 In the first aspect of the present application, a reheated air cloth sealing plate rapping device is provided, which is used to rap the cloth sealing plate 100, and includes a connecting frame 200, a driving assembly 300 and a rapping assembly 400. The cloth sealing plate 100 is connected to the connecting frame 200. The driving assembly 300 includes a motor 320 and a transmission shaft 310 that is transmission-connected to the motor 320. The transmission shaft 310 is rotationally connected to the connecting frame 200, and the transmission shaft 310 is arranged parallel to the cloth sealing plate 100. The rapping assembly 400 is connected to the transmission shaft 310, and the rapping assembly 400 is used to drive the cloth sealing plate 100 to vibrate. When the motor 320 drives the transmission shaft 310 to rotate, the transmission shaft 310 drives the rapping assembly 400 to vibrate the cloth sealing plate 100.

[0041] The heat recovery air sealing plate vibration device disclosed in this embodiment has a simple structure, is easy to maintain, and has a significant cleaning effect. It can effectively improve the operating efficiency and roasting quality of the belt roasting machine, and avoid system shutdown failures caused by the smoke hood pressure exceeding the limit value caused by the adhesive of the sealing plate 100. The improved design of the sealing plate 100 enhances the vibration effect, improves the efficiency of cleaning the adhesive, extends the continuous production cycle, and improves the continuity and stability of the production line. As an important part of the belt roasting machine, the cleanliness of the sealing plate 100 directly affects the operating efficiency and product quality of the equipment. By vibrating the sealing plate 100, it can be ensured that the sealing plate 100 always remains in a clean state, thereby improving the operating efficiency and product quality of the equipment.

[0042] In one embodiment, the rapping assembly 400 includes a rapping felt 420, a rapping hammer 410 and a transmission member 430. The rapping felt 420 is attached to the cloth sealing plate 100. The transmission member 430 is connected to the transmission shaft 310, and the rapping hammer 410 is rotatably connected to the transmission member 430. The rotation axis of the rapping hammer 410 is arranged parallel to the transmission shaft 310, and the rotation axis of the rapping hammer 410 is arranged at intervals from the transmission shaft 310. When the motor 320 drives the transmission shaft 310 to rotate, the transmission shaft 310 drives the transmission member 430 to rotate and causes the rapping hammer 410 to knock the rapping felt 420 to vibrate the cloth sealing plate 100.

[0043] The vibration felt 420 is a soft material attached to the cloth sealing plate 100, which plays the role of transmitting vibration force and buffering. When the vibration hammer 410 hits the vibration felt 420, the vibration felt 420 can evenly transmit the impact force to the cloth sealing plate 100 to avoid direct damage to the cloth sealing plate 100. The vibration felt 420 can usually be made of highly elastic, wear-resistant and durable materials to ensure its stability and reliability in long-term use.

[0044] The rapping hammer 410 is a component that generates a striking force, and transmits a vibration force by striking the rapping felt 420. The rotation axis of the rapping hammer 410 is arranged parallel to the transmission shaft 310, and is spaced a certain distance from the transmission shaft 310. This arrangement ensures that the rapping hammer 410 can strike the rapping felt 420 evenly during the rotation process, thereby achieving comprehensive rapping of the cloth sealing plate 100.

[0045] When the motor 320 drives the transmission shaft 310 to rotate, the transmission member 430 rotates accordingly, and drives the rapping hammer 410 to rotate. When the rapping hammer 410 rotates to a suitable position, it strikes the rapping felt 420, thereby generating a vibration force.

[0046] When the motor 320 drives the transmission shaft 310 to rotate, the transmission shaft 310 transmits power to the rapping hammer 410 through the transmission member 430. The rapping hammer 410 rotates around its rotation axis under the drive of the transmission member 430, and strikes the rapping felt 420 during the rotation. The rapping felt 420 evenly transmits the striking force to the cloth sealing plate 100, causing the cloth sealing plate 100 to vibrate. This vibration can effectively clean or prevent dust, particles or other impurities accumulated on the cloth sealing plate 100, ensuring its continuous and effective operation.

[0047] See also Figure 3 In one embodiment, a protrusion for cooperating with the rapping hammer 410 is provided on the side of the rapping felt 420 facing away from the cloth sealing plate 100 , and the protrusion is located on the rotation path of the rapping hammer 410 .

[0048] The protrusions are located on the side of the rapping felt 420 that faces away from the cloth sealing plate 100. When the rapping hammer 410 strikes the rapping felt 420, it will first contact these protrusions. The shape, size and number of the protrusions can be adjusted according to actual needs to ensure the best match with the rapping hammer 410. The protrusions are designed to be located on the rotation path of the rapping hammer 410. When the rapping hammer 410 rotates under the drive of the transmission member 430, it will directly strike these protrusions. This matching mode can ensure that the striking force of the rapping hammer 410 can be more concentratedly transmitted to the rapping felt 420, thereby improving the rapping effect.

[0049] The raised design enables the striking force of the rapping hammer 410 to be more directly transmitted to the rapping felt 420, reducing energy loss. This helps to improve the rapping efficiency, so that the accumulation on the cloth sealing plate 100 can be cleaned up more quickly. The raised design can also disperse the striking force of the rapping hammer 410, reducing the direct impact on the rapping felt 420 and the cloth sealing plate 100, which helps to extend the service life of the rapping felt 420 and the cloth sealing plate 100, and reduces the cost of replacement and maintenance.

[0050] See also Figure 3 In one embodiment, the transmission member 430 includes a U-shaped bolt 431 and a transmission plate 432. The U-shaped bolt 431 is clamped on the transmission shaft 310, and both ends of the U-shaped bolt 431 are connected to the transmission plate 432, and the rapping hammer 410 is rotatably connected to the transmission plate 432.

[0051] The U-bolt 431 is responsible for fixing the transmission member 430 on the transmission shaft 310. By tightening on the transmission shaft 310, the U-bolt 431 can ensure a stable connection between the transmission member 430 and the transmission shaft 310, thereby transmitting power. The shape of the U-bolt 431 is similar to the English letter "U", and both ends of the U-bolt 431 have threads or other connection structures, which can be connected to the transmission plate 432. The two ends of the U-bolt 431 are connected to the transmission plate 432 in some way (such as fasteners such as bolts and nuts) to form an integral structure. The transmission plate 432 is connected to the end of the U-bolt 431 and is rotatably connected to the rapping hammer 410. This connection method allows the transmission plate 432 to rotate under the drive of the transmission shaft 310, and drives the rapping hammer 410 to perform a knocking operation.

[0052] When the motor 320 drives the transmission shaft 310 to rotate, the transmission shaft 310 transmits power to the transmission plate 432 through the U-shaped bolt 431. The transmission plate 432 rotates with the rotation of the transmission shaft 310 under the fixation of the U-shaped bolt 431. At the same time, since the rapping hammer 410 is rotatably connected to the transmission plate 432, the rapping hammer 410 also rotates under the drive of the transmission plate 432. When the rapping hammer 410 rotates to an appropriate position, it strikes the rapping felt 420, thereby generating a vibration force.

[0053] The combined structure of the U-bolt 431 and the transmission plate 432 ensures a stable connection between the transmission member 430 and the transmission shaft 310, avoiding loosening or falling off when transmitting power. Due to the tight connection between the U-bolt 431 and the transmission plate 432, and the rotational connection between the transmission plate 432 and the rapping hammer 410, the power can be efficiently transmitted to the rapping hammer 410, thereby improving the rapping effect.

[0054] Of course, making the transmission member 430 include the U-bolt 431 and the transmission plate 432 is only one embodiment in the present embodiment. In other embodiments, the transmission member 430 can also be set to a disc, the disc is coaxially arranged with the transmission shaft 310, and at the same time, the rapping hammer 410 is eccentrically arranged with the disc, and the rapping hammer 410 is rotatably connected with the disc, and this mode can also drive the disc to rotate through the transmission shaft 310 and then drive the rapping hammer 410 to knock the rapping felt 420. In addition, it is also possible to set the transmission member 430 to a strip shape, so that one end of the transmission member 430 is fixedly connected with the transmission shaft 310, and the other end thereof is rotatably connected with the rapping hammer 410.

[0055] In one embodiment, a plurality of rapping assemblies 400 are provided, and the plurality of rapping assemblies 400 are arranged at intervals along the length direction of the sealing plate 100 , and the plurality of rapping assemblies 400 are all connected to the transmission shaft 310 .

[0056] The number of the rapping assemblies 400 is determined according to the length of the cloth sealing plate 100 and actual needs. These rapping assemblies 400 are arranged at intervals along the length direction of the cloth sealing plate 100 to ensure comprehensive coverage and uniform rapping of the cloth sealing plate 100. Each rapping assembly 400 is connected to the transmission shaft 310 through a corresponding transmission member 430, and the transmission member 430 may include structures such as a U-bolt 431 and a transmission plate 432, which are used to transmit the power of the transmission shaft 310 to the rapping hammer 410. When the motor 320 drives the transmission shaft 310 to rotate, all the rapping assemblies 400 connected to the transmission shaft 310 will work synchronously, and each rapping hammer 410 will strike the rapping felt 420 at the same time or a similar time, thereby generating a uniform vibration force.

[0057] The provision of multiple rapping assemblies 400 increases the rapping area and frequency of the cloth sealing plate 100, which helps to more effectively clean the accumulation on the cloth sealing plate 100 and improve the operating efficiency of the equipment. The synchronous operation of multiple rapping assemblies 400 can reduce the equipment downtime caused by the failure of a single rapping assembly 400, which improves the stability and reliability of the equipment and ensures the continuous production.

[0058] See also Figure 1 and Figure 2 In one embodiment, an elastic member 220 is provided between the connecting frame 200 and the cloth sealing plate 100. The two ends of the elastic member 220 act on the connecting frame 200 and the cloth sealing plate 100 respectively, and the elastic member 220 makes the cloth sealing plate 100 have a tendency to move away from the connecting frame 200. The cloth sealing plate 100 is connected to the connecting frame 200 by a pre-tightening bolt 230, and the cloth sealing plate 100 and the pre-tightening bolt 230 are slidably matched, so that the cloth sealing plate 100 moves toward the connecting frame 200 when subjected to pressure.

[0059] The function of the elastic member 220 is to provide a tendency for the cloth sealing plate 100 to move away from the connecting frame 200, that is, when there is no external force, the cloth sealing plate 100 will maintain a certain tension state due to the elastic force of the elastic member 220. The cloth sealing plate 100 is connected to the connecting frame 200 through the pre-tightening bolt 230. This connection method allows the cloth sealing plate 100 to move closer to the connecting frame 200 when it is under pressure. The pre-tightening bolt 230 not only plays a connecting role, but also adjusts the initial position and tension of the cloth sealing plate 100 through its pre-tightening force. This sliding fit helps to ensure that the cloth sealing plate 100 can vibrate smoothly when it is under pressure without getting stuck or damaged.

[0060] See also Figure 1 , Figure 2 and Figure 3 In one embodiment, the connecting frame 200 includes a support seat 210, a plurality of intermediate bearing seats 240 and a plurality of top bearing seats 250. The sealing plate 100 is connected to the bottom of the support seat 210. The plurality of intermediate bearing seats 240 are all installed on the top of the support seat 210. The plurality of top bearing seats 250 are arranged at intervals along the length direction of the sealing plate 100, and the plurality of top bearing seats 250 are all located between the intermediate bearing seats 240. The transmission shaft 310 is connected to the plurality of intermediate bearing seats 240 and the plurality of top bearing seats 250.

[0061] The support seat 210 is the base part of the connecting frame 200. It is usually located at the bottom of the connecting frame 200, used to support the weight of the entire connecting frame 200 and fix it to the main structure of the equipment. The design of the support seat 210 should ensure that it can withstand the gravity and vibration forces from components such as the cloth sealing plate 100 and the transmission shaft 310. Multiple intermediate bearing seats 240 are installed on the top of the support seat 210. These bearing seats are used to support the transmission shaft 310 and allow the transmission shaft 310 to rotate smoothly inside them. Multiple top bearing seats 250 are arranged at intervals along the length direction of the cloth sealing plate 100 and are all located between the intermediate bearing seats 240. Similar to the intermediate bearing seats 240, the top bearing seats 250 are also used to support the transmission shaft 310 and allow it to rotate. However, the top bearing seat 250 is located higher, which can further disperse the load on the transmission shaft 310 and improve the stability of the entire connecting frame 200.

[0062] By providing a plurality of intermediate bearing seats 240 and a top bearing seat 250, the stability and support force of the transmission shaft 310 on the entire connecting frame 200 can be ensured. This design helps to reduce the vibration and shaking of the transmission shaft 310 during operation, and improves its operating efficiency and service life. The top bearing seat 250 is located between the intermediate bearing seats 240, which can further disperse the load on the transmission shaft 310. This load-dispersing design helps to reduce the pressure on a single bearing seat, extend its service life, and reduce the risk of equipment failure.

[0063] See also Figure 1 and Figure 4 In one embodiment, the driving assembly 300 further includes a coupling 330 and a sealing assembly 340. The output end of the motor 320 is connected to the transmission shaft 310 through the coupling 330, and the sealing assembly 340 is disposed between the coupling 330 and the transmission shaft 310.

[0064] The motor 320 is the power source of the drive assembly 300, and it is responsible for providing rotational power to drive the transmission shaft 310 to rotate. The selection of the motor 320 should be determined according to actual needs, including its power, speed and type. The transmission shaft 310 is a key component connecting the motor 320 and the cloth sealing plate 100 to rapping the assembly 400. It is responsible for transmitting the rotational power of the motor 320 to the rapping assembly 400 to drive the rapping hammer 410 to perform the knocking action. The design of the transmission shaft 310 should ensure that it has sufficient strength and rigidity to withstand the torque from the motor 320 and the reaction force of the rapping assembly 400. The coupling 330 is used to connect the output end of the motor 320 and the transmission shaft 310 to transmit torque. The coupling 330 usually has an elastic element, which can compensate for the slight displacement and deviation between the motor 320 and the transmission shaft 310, ensuring that the connection between them is stable and reliable. The selection of the coupling 330 should be determined according to the power, speed and size of the transmission shaft 310 of the motor 320. The sealing assembly 340 is disposed between the coupling 330 and the transmission shaft 310 to prevent lubricating oil or other liquids from leaking from the transmission shaft 310 and to prevent external dust and impurities from entering the transmission system. The design of the sealing assembly 340 should ensure that it has good sealing performance and durability to adapt to harsh working environments.

[0065] When the motor 320 is started, its output end transmits the rotational power to the transmission shaft 310 through the coupling 330. The elastic element in the coupling 330 can compensate for the slight displacement and deviation between the motor 320 and the transmission shaft 310, ensuring the smooth transmission of torque. After receiving the rotational power, the transmission shaft 310 transmits it to the transmission member 430 in the rapping assembly 400 of the cloth sealing plate 100, thereby driving the rapping hammer 410 to perform the knocking action. The sealing assembly 340 forms a barrier between the coupling 330 and the transmission shaft 310 to prevent the leakage of lubricating oil and external impurities from entering the transmission system, ensuring the normal operation of the equipment and extending its service life.

[0066] See also Figure 1In one embodiment, the reheated air sealing plate rapping device further includes a pressure sensor 500, which is used to detect the pressure borne by the sealing plate 100. The pressure sensor 500 can monitor the stress of the sealing plate 100 during operation in real time or periodically, and provide key data for the operation and maintenance of the equipment. The pressure sensor 500 can be installed between the sealing plate 100 and the connecting frame 200, or at a position that is in direct contact with the sealing plate 100. The selection of the installation position should ensure that the sensor can accurately and reliably detect the pressure borne by the sealing plate 100.

[0067] When the cloth sealing plate 100 is subjected to pressure, the pressure sensor 500 senses this change and converts it into an electrical signal for output. These electrical signals can be received and processed by the processor of the belt roaster, and corresponding control is made. When the pressure data is greater than or equal to the preset pressure data, the controller controls the motor 320 to work, so as to drive the rapping assembly 400 to drive the cloth sealing plate 100 to vibrate. Thereby, real-time monitoring of the pressure of the cloth sealing plate 100 and the intelligent start and stop of the rapping system are realized.

[0068] Through the above embodiments, the present application has the following beneficial effects or advantages: the heat recovery air sealing plate vibration device disclosed in the present application has a simple structure, is easy to maintain, and has a significant cleaning effect, which can effectively improve the operating efficiency and roasting quality of the belt roasting machine, and avoid system shutdown failures caused by the smoke hood pressure exceeding the limit value caused by the adhesive of the sealing plate 100. The improved design of the sealing plate 100 enhances the vibration effect, improves the efficiency of cleaning the adhesive, extends the continuous production cycle, improves the continuity and stability of the production line, and can avoid personnel from being in a high-temperature working environment for a long time, reduces the danger to personnel, improves operational safety, and improves product quality and production efficiency. Through automated pressure monitoring and controllers, real-time monitoring of the pressure of the sealing plate 100 and intelligent start and stop of the vibration system are realized, effectively avoiding system shutdown failures caused by blockage of the sealing plate 100.

[0069] Based on the same inventive concept, the second embodiment of the present application discloses a belt roasting machine, which includes a main body, a controller and a reheated air cloth sealing plate rapping device according to any embodiment of the first aspect. The controller is installed on the main body. The connecting frame 200 is connected to the main body, and the motor 320 is electrically connected to the controller.

[0070] The belt roasting machine disclosed in the present application has a simple structure, is easy to maintain, and has a significant cleaning effect. It avoids system shutdown failures caused by the smoke hood pressure exceeding the limit value caused by the adhesion of the cloth sealing plate 100. The improved design of the cloth sealing plate 100 enhances the vibration effect, improves the efficiency of cleaning the adhesion, extends the continuous production cycle, and improves the continuity and stability of the production line.

[0071] Based on the same inventive concept, the third aspect of the present application discloses a control method for a belt roasting machine based on any embodiment of the second aspect, which comprises the following steps:

[0072] The controller obtains the pressure data of the sealing plate 100;

[0073] When the pressure data is greater than or equal to the preset pressure data, the controller controls the motor 320 to work, so as to drive the rapping assembly 400 to drive the sealing plate 100 to vibrate;

[0074] After the pressure data is less than the preset pressure, the controller controls the motor 320 to stop working.

[0075] The control method of the belt roaster automatically obtains the pressure data of the cloth sealing plate 100 through the controller, and determines whether it is necessary to start the rapping assembly 400 for rapping operation according to the preset pressure threshold. This automated and intelligent control method not only improves the operating efficiency of the equipment, but also reduces the need for manual intervention, reduces the difficulty of operation and labor costs.

[0076] By monitoring the pressure data of the cloth sealing plate 100 in real time, the controller can respond quickly when the pressure reaches or exceeds the preset threshold, and control the motor 320 to start the rapping assembly 400 for rapping. This real-time response mechanism helps to clean up the accumulation on the cloth sealing plate 100 in time to prevent it from affecting the normal operation of the equipment. At the same time, regular rapping operations can also play a role in preventive maintenance and extend the service life of the cloth sealing plate 100.

[0077] The control method can control the start and stop of the motor 320 according to the actual pressure of the cloth sealing plate 100, thereby avoiding unnecessary energy consumption. When the pressure of the cloth sealing plate 100 is lower than the preset threshold, the motor 320 stops working, thereby achieving energy saving. In addition, by reducing the accumulation on the cloth sealing plate 100, the pollution to the environment can also be reduced, which meets the environmental protection requirements.
