Description

Technical Field

[0001] The utility model belongs to the technical field of tobacco processing, and in particular relates to an intelligent dust removal system for a shredder. Background Art

[0002] The shredder is a device that cuts the processed tobacco leaves or stems into qualified shredded tobacco leaves and stems. It is a key equipment in the shredded tobacco production process. Dust will be generated during the shredding process, so a dust removal system must be set up. The function of the shredder's dust removal system is to collect dust generated during the shredding process, improve the purity of the shredded tobacco after shredding, and improve the working environment of the operator. The reliable operation of the dust removal system plays a vital role in the processing quality of the shredder.

[0003] Usually, one dust collector is connected to multiple wire cutters at the same time, and one dust collector can extract dust from multiple wire cutters. However, in actual use, multiple wire cutters connected to the same dust collector will not run at the same time, and only the running wire cutters need to be extracted by the dust collector.

[0004] In order to avoid wasting wind resources, the existing dust removal system generally adopts the method of inserting a dust removal pipe at the air inlet of the dust collector. That is, when one of the wire cutters is running, the dust removal pipe corresponding to the running wire cutter is inserted into the air inlet of the dust collector, so that the dust collector can remove dust from the corresponding wire cutter; and when the operating state of the wire cutter changes, the dust removal pipe corresponding to the stopped wire cutter is removed, and the dust removal pipe corresponding to the restarted wire cutter is inserted into the air inlet of the dust collector.

[0005] When the above system is used, the dust removal pipe needs to be manually disassembled and assembled, which is inconvenient to use. Utility Model Content

[0006] The purpose of the utility model is to provide an intelligent dust removal system for a shredder, so as to solve the problem of inconvenience in use caused by structural defects of the existing dust removal system.

[0007] In order to achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

[0008] An intelligent dust removal system for a wire cutter, comprising a dust collector and a plurality of wire cutters;

[0009] The dust collector comprises an air inlet pipe, on which a plurality of dust removal pipes are fixedly mounted, and the dust removal pipes are connected to the dust removal port of the shredder;

[0010] The dust removal pipeline is provided with a valve device, the valve device comprising a damper and an adjusting mechanism for adjusting the opening and closing of the damper, and the damper is rotatably installed in the dust removal pipeline;

[0011] It also includes a controller, wherein the input end of the controller is connected to the wire cutter signal, and the output end of the controller is connected to the adjustment mechanism signal;

[0012] When the shredder starts to run, a first pulse signal is sent to the controller, and the controller controls the corresponding regulating mechanism to open the air door based on the first pulse signal;

[0013] When the shredder stops running, a second pulse signal is sent to the controller, and the controller controls the corresponding regulating mechanism to close the air door based on the second pulse signal.

[0014] It is further defined that the damper is a butterfly damper. Such a structural design can block and open the dust removal duct through the butterfly damper, which has a simple structure and strong practicality.

[0015] It is further defined that the controller adjusts the opening of the corresponding air door based on the preset wire cutting frequency of the wire cutting machine, wherein the preset wire cutting frequency of the wire cutting machine is positively correlated with the opening of the air door, that is, the faster the preset wire cutting frequency of the wire cutting machine, the larger the opening of the air door on the corresponding dust removal duct, until the air door opening reaches the maximum value; and vice versa, until the air door is completely closed.

[0016] This structural design adjusts the air door opening through the preset cutting frequency of the shredder. When the preset cutting frequency of the shredder is accelerated, the dust generated by the shredder when cutting tobacco leaves increases. At this time, increasing the opening of the air door can increase the adsorption of the dust generated by the shredder to avoid dust accumulation. Conversely, when the preset cutting frequency of the shredder is low, reducing the opening of the air door can reduce the waste of wind resources of the dust collector, and it is more practical.

[0017] It is further defined that a temperature sensor is fixedly installed in the air inlet duct, and the temperature sensor is connected to the input terminal signal of the controller;

[0018] It also includes a first alarm, which is signal-connected to the output terminal of the controller;

[0019] When the temperature sensor detects that the temperature in the air inlet pipe is higher than the preset temperature, a third pulse signal is sent to the controller, and the controller controls the first alarm to issue an alarm prompt based on the third pulse signal.

[0020] This structural design detects the temperature of the air entering the air inlet duct through a temperature sensor. When the air temperature in the air inlet duct is higher than the preset temperature, the first alarm will sound an alarm. This can avoid the safety hazard of combustion of substances inside the dust collector caused by the air temperature entering the dust collector being too high. It is very practical.

[0021] It is further defined that a pressure sensor is installed in the air inlet pipe, and the pressure sensor is connected to the input terminal signal of the controller;

[0022] The controller adjusts the opening of the damper in the open state based on the pressure detected by the pressure sensor, wherein the pressure detected by the pressure sensor is negatively correlated with the opening of the damper, that is, the smaller the pressure detected by the pressure sensor, the larger the opening of the damper in the open state, until the damper opening reaches a maximum value, and vice versa.

[0023] This structural design detects the pressure in the air inlet duct through a pressure sensor. When the dust removal duct in use is partially blocked by tobacco, the pressure detected by the pressure sensor in the air inlet duct decreases. At this time, the controller increases the opening of the damper to keep the wind speed in the air inlet duct at a normal usage state, which is very practical.

[0024] It is further defined that it also includes a second alarm, wherein the second alarm is signal-connected to the output terminal of the controller;

[0025] When the air door opening reaches the maximum value and the pressure detected by the pressure sensor is lower than the preset pressure, the controller controls the second alarm to issue an alarm prompt.

[0026] Such a structural design, through the mutual cooperation of the second alarm and the pressure sensor, when the air door opening reaches the maximum value and the pressure detected by the pressure sensor is lower than the preset pressure, it indicates that the corresponding dust removal duct is severely blocked by tobacco. At this time, the second alarm will issue an alarm prompt to warn the operator, which is convenient for the operator to maintain and is highly practical.

[0027] The utility model adopting the above technical solution has the following advantages:

[0028] 1. Through the cooperation of the wire cutter, controller and valve device, the opening and closing of the damper on the corresponding dust removal pipeline is controlled according to the running state of the wire cutter, so as to realize the automatic control of the dust removal pipeline. There is no need to manually disassemble and assemble the dust removal pipeline, which is more convenient to use and more practical.

[0029] 2. The damper opening is adjusted by the preset cutting frequency of the shredder. When the preset cutting frequency of the shredder is accelerated, the dust generated by the shredder when cutting tobacco leaves increases. At this time, increasing the damper opening can increase the adsorption of the dust generated by the shredder to avoid dust accumulation; conversely, when the preset cutting frequency of the shredder is low, reducing the damper opening can reduce the waste of wind resources of the dust collector, which is more practical.

[0030] 3. The temperature of the air entering the air inlet pipe is detected by the temperature sensor. When the air temperature in the air inlet pipe is higher than the preset temperature, the first alarm will sound an alarm, which can avoid the safety hazard of the material inside the dust collector being burned due to the excessively high air temperature entering the dust collector. It is very practical.

[0031] 4. The pressure in the air inlet pipe is detected by the pressure sensor. When the dust removal pipe in use is partially blocked by tobacco, the pressure detected by the pressure sensor in the air inlet pipe decreases. At this time, the controller increases the opening of the damper to keep the wind speed in the air inlet pipe at a normal use state, which is very practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The main component symbols are described as follows:

[0035] Dust collector 1, air inlet pipe 11, dust removal pipeline 2, valve device 3. DETAILED DESCRIPTION

[0036] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that in the drawings or in the specification, similar or identical parts use the same figure numbers, and the implementation methods not shown or described in the drawings are forms known to ordinary technicians in the relevant technical field. In addition, the directional terms mentioned in the embodiments, such as "upper", "lower", "top", "bottom", "left", "right", "front", "back", etc., are only referenced to the directions of the drawings and are not used to limit the scope of protection of the present invention.

[0037] like Figure 1 As shown, the utility model is an intelligent dust removal system for a wire cutting machine, comprising a dust collector 1 and a plurality of wire cutting machines;

[0038] The dust collector 1 includes an air inlet pipe 11, on which a plurality of dust removal pipes 2 are fixedly mounted, and the dust removal pipes 2 are connected to the dust removal port of the shredder;

[0039] A valve device 3 is installed on the dust removal pipeline 2, and the valve device 3 includes a damper and an adjusting mechanism for adjusting the opening and closing of the damper, and the damper is rotatably installed in the dust removal pipeline 2;

[0040] It also includes a controller, the input end of the controller is connected to the wire cutter signal, and the output end of the controller is connected to the adjustment mechanism signal;

[0041] When the shredder starts to run, a first pulse signal is sent to the controller, and the controller controls the corresponding regulating mechanism to open the air door based on the first pulse signal;

[0042] When the shredder stops running, a second pulse signal is sent to the controller, and the controller controls the corresponding regulating mechanism to close the air door based on the second pulse signal.

[0043] The air door is a butterfly-shaped air door. The dust removal duct 2 is blocked and opened by the butterfly-shaped air door, which has a simple structure and strong practicality.

[0044] The controller adjusts the opening of the corresponding air door based on the preset wire cutting frequency of the wire cutter, wherein the preset wire cutting frequency of the wire cutter is positively correlated with the opening of the air door, that is, the faster the preset wire cutting frequency of the wire cutter, the larger the opening of the air door on the corresponding dust removal duct 2, until the air door opening reaches the maximum value; vice versa, until the air door is completely closed.

[0045] The damper opening is adjusted by the preset cutting frequency of the shredder. When the preset cutting frequency of the shredder is accelerated, more dust is generated when the shredder cuts tobacco leaves. At this time, increasing the damper opening can increase the adsorption of the dust generated by the shredder to avoid dust accumulation. On the contrary, when the preset cutting frequency of the shredder is low, reducing the damper opening can reduce the waste of wind resources of the dust collector 1, which is more practical.

[0046] A temperature sensor is fixedly installed in the air inlet pipe 11, and the temperature sensor is connected to the input signal of the controller;

[0047] It also includes a first alarm, which is connected to the output terminal signal of the controller;

[0048] When the temperature sensor detects that the temperature in the air inlet pipe 11 is higher than the preset temperature, a third pulse signal is sent to the controller, and the controller controls the first alarm to issue an alarm prompt based on the third pulse signal.

[0049] The temperature of the air entering the air inlet pipe 11 is detected by a temperature sensor. When the air temperature in the air inlet pipe 11 is greater than the preset temperature, the first alarm sends out an alarm prompt, which can avoid the safety hazard of combustion of the substances inside the dust collector 1 caused by the air temperature entering the dust collector 1 being too high, and has strong practicality.

[0050] A pressure sensor is installed in the air inlet pipe 11, and the pressure sensor is connected to the input end signal of the controller;

[0051] The controller adjusts the opening of the damper in the open state based on the pressure detected by the pressure sensor, wherein the pressure detected by the pressure sensor is negatively correlated with the opening of the damper, that is, the smaller the pressure detected by the pressure sensor, the larger the opening of the damper in the open state, until the damper opening reaches the maximum value, and vice versa.

[0052] The pressure in the air inlet pipe 11 is detected by a pressure sensor. When the dust removal pipe 2 in use is partially blocked by tobacco, the pressure detected by the pressure sensor in the air inlet pipe 11 decreases. At this time, the controller increases the opening of the air door, so that the wind speed in the air inlet pipe 11 can be maintained in a normal use state, which is very practical.

[0053] It also includes a second alarm, which is connected to the output terminal signal of the controller;

[0054] When the air door opening reaches the maximum value and the pressure detected by the pressure sensor is lower than the preset pressure, the controller controls the second alarm to issue an alarm prompt.

[0055] Through the cooperation between the second alarm and the pressure sensor, when the air door opening reaches the maximum value and the pressure detected by the pressure sensor is lower than the preset pressure, it means that the corresponding dust removal duct 2 is seriously blocked by tobacco. At this time, the second alarm will issue an alarm to warn the operator, which is convenient for the operator to maintain and has strong practicality.

[0056] In this embodiment, when in use, one of the wire cutters starts to run at a preset wire cutting frequency, sends a first pulse signal to the controller, controls the air door in the valve device 3 on the corresponding dust removal pipeline 2 to open at a corresponding opening, and at this time, the dust collector 1 generates negative pressure, and the dust is removed from the corresponding wire cutter through the air inlet pipe 11 and the corresponding dust removal pipeline 2;

[0057] When the dust removal duct 2 in use is partially blocked by tobacco, the pressure detected by the pressure sensor in the air inlet duct 11 decreases, and the controller increases the opening of the damper at this time, so that the wind speed in the air inlet duct 11 can be maintained in a normal use state;

[0058] When the air door opening reaches the maximum value and the pressure detected by the pressure sensor is lower than the preset pressure, it means that the corresponding dust removal duct 2 is seriously blocked by tobacco shreds. At this time, the second alarm will sound an alarm to warn the operator;

[0059] When the air temperature in the air inlet pipe 11 is greater than the preset temperature, the first alarm will sound an alarm;

[0060] When the shredder stops running, a second pulse signal is sent to the controller to control the air door in the valve device 3 on the corresponding dust removal pipeline 2 to close.

[0061] The above is a detailed introduction to an intelligent dust removal system for a shredder provided by the utility model. The description of the specific embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, several improvements and modifications can be made to the utility model, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
