Description

Technical Field

[0001] This utility model belongs to the technical field of silk-making equipment, specifically relating to a cleaning device for the inside of a lifting belt. Background Technology

[0002] In the silk-making workshop, materials are transported between cleaning, unpacking, silk-making, drying, and flavoring equipment via conveyor belts. When there is a height difference in the transport, an elevator belt is used as an important auxiliary device to achieve simultaneous transport and lifting. The elevator belt is driven by a geared motor that drives a sprocket, which in turn drives two chains on the left and right. The belt is fixed to the two chains by a crossarm and moves simultaneously with the chains.

[0003] During the production process, tobacco leaves or shreds will inevitably break down to some extent, producing fine tobacco dust that leaks through the gaps in the side guards of the elevator belt into the back interlayer of the operating elevator belt and adheres to the two chains. If too much tobacco dust adheres, it will cause the chains to jam and the lubrication effect to deteriorate. The tobacco dust deposited inside the chain will form tobacco grime, causing abnormal wear of the chain and making it easy for teeth to skip at the upper part or tail of the chain. This will cause the elevator belt to run abnormally and stop, and in severe cases, it will damage the sprockets, chains and crossarms. Utility Model Content

[0004] The purpose of this utility model is to provide an internal cleaning device for a lifting belt, in which the cleaning structure operates simultaneously when the lifting belt is running. The device removes soot and dust from the lifting belt through a dust removal shell and dust removal port, and cleans the dust accumulated on the back of the lifting belt through a brush, and then removes the cleaned dust through the dust removal port; thereby solving the problems mentioned in the background art.

[0005] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A cleaning device for the interior of a lifting belt is provided for cleaning the interior of the lifting belt. The device includes a support and a cleaning structure. The support has at least one mounting hole. The cleaning structure includes a dust removal shell and a brush. The dust removal shell has at least a dust removal chamber and a dust removal port communicating with the dust removal chamber. The dust removal ports are located on both sides of the bottom of the dust removal shell. Both ends of the dust removal shell have connection ports communicating with the dust removal chamber, and these connection ports are inserted into the mounting holes. The bottom of the dust removal shell has a mounting portion, and the brush is mounted on the mounting portion. The brush is located between the two dust removal ports, and the height of the brush's brushing surface is lower than the opening height of the dust removal ports.

[0007] In this application, when materials such as tobacco packs and stacks are lifted by a conveyor belt, tobacco shreds or dust inevitably fall onto the conveyor belt. Furthermore, fine dust leaks from the gaps in the side guards of the conveyor belt into the back layer of the moving conveyor belt, adhering to the two chains and causing chain jamming and reduced lubrication. In this device, the brush and dust collector are located in the back layer of the conveyor belt, parallel to the back of the conveyor belt. The length of the brush is equal to the length of the belt itself, and the length of the dust collector is equal to the length between the two chains of the conveyor belt. The dust collection port is flat, similar to a vacuum cleaner nozzle. The cleaning structure operates simultaneously with the conveyor belt, using the brush to scrub and clean the dust accumulated on the back of the conveyor belt, and using negative pressure to suck away the leaked tobacco dust, cleaned tobacco dust, and other dust through the dust collection port.

[0008] Furthermore, a telescopic component connects the dust collector housing and the brush, and the telescopic component is electrically connected to a controller. The controller controls the movement of the brush relative to the dust collector housing via the telescopic component to clean the interior of the lifting belt. The controller can be set with a timer function, controlling the telescopic component to operate at required intervals, causing the brush to contact the interior of the lifting belt for cleaning. This eliminates the need for constant contact with the lifting belt, reducing unnecessary wear and extending its service life.

[0009] Furthermore, the mounting part includes a slot formed at the bottom of the dust collector housing, a guide hole formed within the slot, and a guide rod connected to the top of the brush, the guide rod slidingly engaging with the guide hole. This allows for convenient disassembly and installation of the brush, and also facilitates easy replacement when the brush needs to be replaced.

[0010] Furthermore, the dust collector housing is provided with an air inlet chamber and an air inlet interface communicating with the air inlet chamber, with the air inlet interface located at both ends of the dust collector housing; the brush includes a brush body and bristles mounted on the brush body; a conical cavity is formed inside the brush body, and an air outlet is formed at the bottom of the conical cavity; a connecting pipe is provided at the center of the guide rod, with one end of the connecting pipe connected to the air inlet chamber and the other end connected to the conical cavity. This structural design allows for self-cleaning of the brush by pumping air through the air inlet interface, allowing the gas to pass through the air inlet chamber and the connecting pipe into the conical cavity, and then being blown out from the air outlet at the bottom of the conical cavity to blow away dust from the brush; this reduces the accumulation of soot on the brush, restores the brush's normal function, and maintains long-term stability. In addition, the dust (including soot) blown away by the brush can be suctioned out through the dust collection port using negative pressure.

[0011] Furthermore, the two ends of the brush body are connected to limiting shafts, which are connected to the mounting holes. A spring is connected between the limiting shafts and the air inlet. The spring can cooperate with the telescopic component, providing an extension force to ensure good contact between the brush and the back of the lifting belt. The movement of the telescopic component can move the brush, releasing it from contact with the back of the lifting belt; the spring and the telescopic component work together to achieve the brushing function.

[0012] Furthermore, the cleaning structure also includes a secondary dust collector housing; the bracket has an installation notch for installing the secondary dust collector housing. If the dust collector housing is installed at one end of the bracket located in the inner interlayer of the lifting belt, the secondary dust collector housing can be installed at the other end of the bracket through the installation notch; an air extraction nozzle is provided on one side of the secondary dust collector housing, and the air extraction nozzle is installed obliquely upward towards the dust collector housing.

[0013] The utility model adopting the above technical solution has the following advantages:

[0014] In this application, a cleaning structure is used to clean the interior of the lifting belt. The structure includes a brush and a dust collector housing located in the back layer of the lifting belt, and is installed and fixed by a bracket. The brush and dust collector housing are parallel to the back of the lifting belt. The length of the brush is equal to the length of the belt itself, and the length of the dust collector housing is equal to the length between the two chains of the lifting belt. The cleaning structure operates simultaneously with the lifting belt, using the brush to scrub and clean the dust accumulated on the back of the lifting belt. Negative pressure is used to suck away any leaked smoke, cleaned smoke, and dust through the dust collection port. Furthermore, the brush does not need to be constantly scrubbing. Through a telescopic component, or a combination of a telescopic component and a spring, the brush can be adjusted to contact or disengage from the back of the lifting belt, allowing for direct and flexible adjustment. The structure is compact, and the overall structure is simple, low-cost, and highly practical. Attached Figure Description

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0026] like Figures 1-6As shown in the figure, an internal cleaning device for a lifting belt according to an embodiment of the present invention is used to clean the inside of the lifting belt. The lifting belt is driven by a gear (specifically a sprocket 102, which can mesh with the chain 103) driven by a reduction motor 101, which in turn drives two chains 103 on the left and right. The belt 105 is fixed to the two chains 103 by a crossbeam and runs simultaneously with the chains 103. A baffle is installed on the outside of the chain 103 to protect the belt 105 during operation. The internal cleaning device of the lifting belt includes a bracket 100 and a cleaning structure 200. The bracket 100 has a T-shaped mounting hole 104. The cleaning structure 200 includes a dust removal shell 201 and a brush 205. The dust removal shell 201 is provided with a dust removal chamber 214 and a dust removal port 204 communicating with the dust removal chamber 214. The dust removal port 204 is located on both sides of the bottom of the dust removal shell 201. Both ends of the dust removal shell 201 are provided with connection ports 202 that communicate with the dust removal chamber 214. The connection ports 202 are inserted into the mounting hole 104. The dust removal shell 201 is installed through the connection ports 202, and a flexible hose is connected through the connection ports 202. The flexible hose is then connected to the negative pressure pipe of a negative pressure device such as an exhaust fan. The negative pressure device generates negative pressure and acts on the dust removal chamber 214, and the dust removal port 204 performs negative pressure dust removal. The bottom of the dust collector housing 201 has a mounting section, on which a brush 205 is mounted. The brush 205 is located between two dust collection ports 204, and the height of the brushing surface of the brush 205 is lower than the opening height of the dust collection ports 204. The brushing surface of the brush 205 is the contact surface between the brush and the back of the lifting belt. The dust collection ports 204 are located on both sides of the bottom of the dust collector housing 201. Negative pressure dust removal can be performed on the back of the lifting belt before and after cleaning with the brush 205. Dust that cannot be removed is then cleaned by the brush 205, and the dust removed by the brush 205 is sucked away by the dust collection ports 204.

[0027] In fact, the mounting section includes a slot at the bottom of the dust collector housing 201, with a guide hole inside the slot. A guide rod is connected to the top of the brush 205, and the guide rod is inserted into the guide hole. This allows for easy disassembly and installation of the brush 205, and also facilitates easy replacement when the brush 205 needs to be replaced. The dust collection port 204 is flat, similar to a vacuum cleaner nozzle; it has good dust collection efficiency. In this embodiment, the device can have two or more cleaning structures 200 for lifting belts of different lengths. All the dust collector housings 201 in the cleaning structures 200 can be connected to a common negative pressure pipe to achieve negative pressure suction. Of course, in this embodiment, the dust collector housing 201 can also be installed without a slot, with the guide hole directly formed at the bottom of the dust collector housing 201.

[0028] In this embodiment, Figure 1For example, the lifting belt rotates clockwise at a speed V; V can be set as needed. While the lifting belt is running, the cleaning structure 200 operates simultaneously, using brushes 205 to scrub and clean the dust accumulated on the back of the lifting belt, and suctioning away any spilled smoke, cleaned smoke, and dust through the dust collection port 204. In fact, corresponding to the T-shaped mounting hole 104, the connection port 202 is set as a rectangular pipe, which can both allow for insertion and positioning with the mounting hole 104, and also connect to the negative pressure pipe.

[0029] In this embodiment, the guide rod slides into the guide hole, and the brush 205 is telescopic. A telescopic component is connected between the dust collector housing 201 and the brush 205. The telescopic component can be a telescopic air rod 213, which is electrically connected to a controller. The controller controls the movement of the brush 205 relative to the dust collector housing 201 through the telescopic air rod 213 to clean the inside of the lifting belt.

[0030] In practice, the telescopic component can be an electric actuator, which is electrically connected to the controller. The controller can be a conventional PLC controller; such as a Siemens S7-200 SMART, Mitsubishi FX3U, or Xinje XC series, which is low-cost and enables control of the telescopic component.

[0031] In fact, the controller can be set with a timer function to control the electric push rod to move according to the required cycle, driving the brush 205 to come into contact with the inside of the lifting belt and clean the inside of the lifting belt; thus reducing unnecessary wear on the lifting belt and extending its service life.

[0032] In practice, a camera can be installed on the bracket and connected to the controller. The controller acquires monitoring data of the inside of the lifting belt through the camera, analyzes the dust accumulation inside the lifting belt, and controls the movement of the telescopic components based on the analysis results. This, in turn, uses brush 205 to clean the inside of the lifting belt, thus automatically completing the cleaning of the inside of the lifting belt. This ensures the normal operation of the silk-making equipment, preventing chain skipping, component damage, or abnormal shutdowns, and greatly reducing the downtime and material shortage rate of the process.

[0033] In this embodiment, as Figure 6As shown, the dust collector housing 201 is provided with an air inlet chamber 210 and an air inlet interface 203 communicating with the air inlet chamber 210. The air inlet interface 203 is located at both ends of the dust collector housing 201. The brush 205 includes a brush body 206 and brush bristles 207 installed on the brush body 206. A conical cavity 212 is opened inside the brush body 206, and an air outlet 208 is opened at the bottom of the conical cavity 212. A connecting pipe 211 is provided at the center of the guide rod. One end of the connecting pipe 211 is connected to the air inlet chamber 210, and the other end of the connecting pipe 211 is connected to the conical cavity 212. The air inlet interface 203 can pass through the mounting hole 104 to connect to an air inlet pipe, which is connected to the factory's air pipeline and indirectly connected to the factory's air compressor equipment. When self-cleaning of the brush 205 is required, cleaning gas is pumped in through the air inlet 203. The gas enters the conical cavity 212 through the air inlet chamber 210 and the connecting pipe 211, and is blown out from the air outlet 208 at the bottom of the conical cavity 212 to blow away dust from the brush 205. This can reduce the accumulation of soot on the brush 205 and keep the brush 205 functioning normally.

[0034] In fact, limiting shafts 209 are connected to both ends of the brush body 206. The limiting shafts 209 are connected to the mounting holes 104 and can slide up and down in the mounting holes 104. A spring (not shown in the figure) is connected between the limiting shafts 209 and the air inlet 203. The spring can cooperate with the telescopic air rod 213, and the spring provides an extension force to keep the brush 205 in good contact with the back of the lifting belt. When the telescopic air rod 213 retracts, it can drive the brush 205 to move, releasing the brush 205 from contact with the back of the lifting belt, and putting it into standby mode.

[0035] In this embodiment, as Figure 6 , Figure 7 As shown, the cleaning structure 200 also includes a secondary dust collector housing 220; the bracket 100 has an installation notch 106 for installing the secondary dust collector housing 220. If the dust collector housing 201 is installed at one end of the bracket 100 located in the inner layer of the lifting belt, the installation notch 106 can be opened at the other end of the bracket, thereby installing the secondary dust collector housing 220 at the other end of the bracket; an exhaust nozzle 221 is provided on one side of the secondary dust collector housing 220, and the exhaust nozzle 221 is opened obliquely upward facing the dust collector housing 201. A secondary dust collector chamber 222 is provided inside the secondary dust collector housing 220, and exhaust ports 223 connected to the secondary dust collector chamber 222 are provided at both ends of the secondary dust collector housing 220. The exhaust ports 223 can be connected to a negative pressure pipe. The negative pressure generated by the negative pressure pipe acts on the exhaust nozzle 221 through the secondary dust collector chamber 222 to remove dust from the back of the lifting belt near the exhaust nozzle 221.

[0036] In fact, a top air extraction port 224 is provided at the top of the secondary dust collector housing 220, and the top air extraction port 224 is connected to the secondary dust collector chamber 222. The position of the top air extraction port 224 corresponds to the position of the two chains 103 of the lifting belt; the top air extraction port 224 mainly performs negative pressure dust removal on the chains 103.

[0037] In fact, in this embodiment, air extraction nozzles 221 can also be provided on both sides of the secondary dust collector housing 220; the air extraction nozzles 221 are inclined upwards.

[0038] This structural design utilizes a cleaning structure 200 to remove smoke, dust, and other contaminants that have seeped into the lifting belt. The brushes 205 within the cleaning structure 200 target stubborn dust accumulation, and, in conjunction with the dust collection shell 201, suck up and discharge the cleaned dust. Multiple dust collection shells 201 can be configured as needed, connected to a central negative pressure pipe for centralized negative pressure dust removal. The telescopic components allow the brushes 205 to perform contact cleaning as required, preventing unnecessary wear on the lifting belt. Additionally, a secondary dust collection shell 220 without brushes 205 can be included to assist the cleaning work of the dust collection shells 201 and brushes 205, achieving a balance between construction cost and cleaning effectiveness. The dust collection shells 201 and secondary dust collection shells 220 work together at the beginning and end of the lifting belt, providing comprehensive coverage of the entire lifting process and a wide cleaning range. The overall structure is simple and highly practical.

[0039] The above provides a detailed description of a lifting belt internal cleaning device provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
