Description

Technical Field

[0001] The present invention relates to the technical field of respirator production, and particularly relates to a tank feeding device for respirator production. Background Art

[0002] A fire escape mask is an escape equipment for sudden fires. The filter gas tank is an important part of the fire escape mask. When assembling the filter gas tank, usually, filter cloth one is first laid in the tank body, and the tank body with filter cloth one laid is placed on the conveying device. After the conveying device conveys the tank body to the filling mechanism, the operation of the conveying device is stopped. Then, the catalyst layer, filter cloth two, and activated carbon layer are sequentially laid in the tank body by the filling mechanism. Finally, the filled tank body is conveyed backward and taken down. Finally, the tank body is encapsulated by the encapsulation mechanism to assemble and form the filter gas tank.

[0003] A Chinese patent document with the publication number of CN113979094B discloses a tank lane-dividing mechanism, which includes a tank lane-dividing execution total module, a tank body detection device, a transmission device, and a track module. The tank lane-dividing execution total module includes a tank-blocking following component, a total tank-blocking mechanism, double-sided fixing plates, and a tank body displacement total component. The tank-blocking following component is fixedly connected to the transmission device. The total tank-blocking mechanism is arranged above the transmission device. The tank body displacement total component is located above the transmission device and on one side of the total tank-blocking mechanism. The tank body detection device is arranged on the transmission device.

[0004] In the existing tank lane-dividing mechanism, in the initial startup state of the production line, the cans move in a row from the middle position of the track. The tank-blocking following component is in the tank-blocking state, the following-end tank-blocking mechanism is in the tank-blocking state, and the displacement-end tank-blocking mechanism is in the release state. When the equipment starts to run, the cans will run in sequence. When the tank detection board detects a can, and the in-tank end detection device detects a can continuously for a period of time, and at the same time the tank-blocking following component is in place and there is no can being blocked, a signal is sent at this time to make the front-side tank body displacement component and the rear-side tank body displacement component act synchronously to move the can to the required channel. The following-end tank-blocking mechanism opens to release the can, and at the same time the displacement-end tank-blocking mechanism blocks the cans in the subsequent lane. The released cans run continuously. After the cans are output, the can-aligning component of the following component will block the cans during the running process, and then the telescopic mechanism of the following component will lift the can-aligning component of the following component to release the sorted cans to prepare for the subsequent process, and then a new cycle is carried out. The front-side tank body displacement component and the rear-side tank body displacement component act simultaneously, and at the same time as the action is completed, there is an orbit channel to accommodate new cans to come in.

[0005] However, the above-mentioned existing technologies still have the following deficiencies: after the catalyst layer, the second filter cloth, and the activated carbon layer are sequentially laid in the tank, due to the small thickness of the second filter cloth, the distance between the catalyst layer and the activated carbon layer is small. When the tank is continuously driven by the conveying device to move, affected by the operation of the conveying device, the tank is prone to vibration, and the catalyst layer or the activated carbon layer may pass over the second filter cloth, resulting in partial mixing of the catalyst and the activated carbon, thereby affecting the gas filtering effect of the gas filter tank. Summary of the Invention

[0006] The present invention provides a tank feeding device for respirator production, aiming to solve the problem that when the conveying device conveys the tank, the tank vibrates, resulting in partial mixing of the catalyst and the activated carbon.

[0007] The tank feeding device for respirator production of the present invention includes a circular conveying mechanism and a linear conveying mechanism for conveying the tank, and further includes a pressing mechanism. The pressing mechanism includes a transmission member and a plurality of pressing members. The transmission member is connected to the linear conveying mechanism, and the transmission member can drive the pressing members to move synchronously with the tank. A plurality of pressing members are all connected to the transmission member. The tank is sequentially filled with a catalyst layer, a second filter cloth, and an activated carbon layer; the pressing member includes a first channel and a pressing part. The pressing part is arranged on the first channel, and air pressure is applied to the first channel. Through the air pressure, the pressing part can be driven to move into the tank and press the activated carbon layer in the tank.

[0008] Beneficial effects: The tank is conveyed by the circular conveying mechanism to the linear conveying mechanism, and then conveyed by the linear conveying mechanism to the filling mechanism. Through the filling mechanism, the catalyst layer, the second filter cloth, and the activated carbon layer are sequentially conveyed into the tank. After filling, air pressure is applied to the first channel, so that the air pressure inside the first channel increases. At this time, the pressing part can be driven to move downward through the air pressure until the pressing part moves into the tank. At the same time, the pressing part presses the activated carbon layer in the tank, so that the catalyst layer, the second filter cloth, and the activated carbon layer are sequentially in close contact. After pressing the activated carbon layer in the tank, when the linear conveying mechanism drives the tank filled with the catalyst layer, the second filter cloth, and the activated carbon layer to continue to move, the transmission member drives the pressing member extending into the tank to move synchronously, so that the pressing part on the pressing member moves synchronously with the tank, so as to avoid partial mixing of the catalyst and the activated carbon caused by the vibration of the tank during the operation of the linear conveying mechanism, thereby ensuring the gas filtering effect of the finished gas filter tank.

[0009] Preferably, the pressing member further includes a second channel, a first elastic part, a piston, and a second elastic part. The second channel is inserted into one end of the first channel, the piston is inserted into the other end of the first channel, the pressing part is inserted onto the second channel, the first elastic part is connected between the second channel and the pressing part, and the second elastic part is connected between the piston and the first channel. The effect is that when the piston moves towards the inside of the first channel, it can push the second channel to move under the action of air pressure, thereby driving the pressing part to move above the tank body. After the second channel is blocked by the first channel and stops moving, the piston continues to move, and can push the pressing part downward into the tank body through air pressure, so as to provide power for the pressing part to press the activated carbon layer in the tank body.

[0010] Preferably, the pressing mechanism further includes a housing, and the transmission member is installed in the housing. The effect is that the housing can provide support for the transmission member.

[0011] Preferably, the transmission member includes a transmission belt and two transmission rollers. The two transmission rollers are both rotatably connected in the housing, the transmission belt is drivingly connected between the two transmission rollers, and the first channel is connected to the transmission belt. The effect is that through the transmission between the transmission belt and the two transmission rollers, power can be provided for the movement of the pressing member.

[0012] Preferably, the pressing mechanism further includes a support member. The support member includes a guide rail and multiple sets of rolling structures. The guide rail is connected in the housing, and multiple sets of rolling structures are respectively connected to multiple first channels. The rolling structure includes a connecting part and three rotating parts. The connecting part is connected to the first channel, and the three rotating parts are all rotatably connected to the connecting part. The three rotating parts are all in rolling contact with the guide rail. The effect is that when air pressure is applied to the first channel, the support member supports and limits the first channel to prevent damage to the connection between the first channel and the transmission belt.

[0013] Preferably, the three rotating parts are arranged in a triangle.

[0014] Preferably, a side plate surface is provided in the housing, and an opening is provided on the outside of the housing.

[0015] Preferably, the pressing mechanism further includes a driving member. The driving member includes a telescopic part and a push plate. The telescopic part is connected to the housing, and the push plate is connected to the telescopic end of the telescopic part. The effect is that the push plate can push the piston to move until the end face of the piston is in the same plane as the side plate surface, so that after the piston is separated from the push plate, the side plate surface can block and position the piston, so that the pressing part can still maintain the state of pressing the activated carbon layer in the tank body under the action of air pressure.

[0016] Preferably, the blanking mechanism further includes a guiding portion, which is connected to the housing and is inclined. The effect is that when the tank body moves to the end of the linear conveying mechanism, the piston on the corresponding pressing member contacts the guiding portion. At this time, the piston is driven by the second elastic portion and gradually resets under the guidance of the guiding portion, so as to avoid taking out part of the activated carbon in the tank body due to the negative pressure generated by the rapid reset of the pressing portion.

[0017] Preferably, it further includes an intermittent feeding mechanism, which is connected to the linear conveying mechanism. The intermittent feeding mechanism includes a separating portion inserted into the linear conveying mechanism, and the separating portion can approach or move away from the tank body. The effect is that the tank bodies can be fed at equal intervals by the movement of the tank bodies.

[0018] The beneficial effects of the present invention are as follows:

[0019] 1. The driving member pushes the piston to move into the first channel and compresses the second elastic portion until the end face of the piston is in the same plane as the side plate surface. At this time, under the air pressure inside the first channel, the second channel and the pressing portion are pushed to move. And under the action of the first elastic portion, the pressing portion will not move downwards. After the pressing portion moves to directly above the tank body after filling, the first channel limits the second channel, and the second channel stops moving. At this time, the piston continues to move towards the direction of extending into the first channel, and can push the pressing portion to move downwards into the tank body under the action of air pressure, and press the activated carbon layer in the tank body, so as to avoid partial mixing of the catalyst and the activated carbon due to the vibration of the tank body caused by the operation of the linear conveying mechanism, thereby ensuring the air filtering effect of the finished air filter tank.

[0020] 2. When the piston moves in the first channel, the first channel is supported and limited by the supporting member to avoid damage to the connection between the first channel and the conveyor belt.

[0021] 3. When the tank body moves to the end of the linear conveying mechanism, the piston on the corresponding pressing member contacts the guiding portion. At this time, the piston is driven by the second elastic portion and gradually resets under the guidance of the guiding portion, so as to avoid taking out part of the activated carbon in the tank body due to the negative pressure generated by the rapid reset of the pressing portion.

[0022] 4. The driving source one drives the pushing portion to rotate, and the circular protrusion on the pushing portion can push the separating portion to approach or move away from the tank body, so as to realize the equal-interval feeding of the tank bodies. Description of the Drawings

[0034] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0035] As Figures 1 to 9As shown in the figure, the tank feeding device for the production of the respirator of the present invention includes a circular conveying mechanism 1, a linear conveying mechanism 2, an intermittent feeding mechanism 3 and a pressing mechanism 4. The linear conveying mechanism 2 is connected to the circular conveying mechanism 1. The circular conveying mechanism 1 can convey the tank A to the linear conveying mechanism 2. The linear conveying mechanism 2 can convey the tank A to the filling mechanism (the filling mechanism is a prior art and is not shown in the figure), and the filling mechanism sequentially lays a catalyst layer, a second filter cloth and an activated carbon layer in the tank A. The intermittent feeding mechanism 3 is connected to the linear conveying mechanism 2 and can feed the tank A on the linear conveying mechanism 2 at equal intervals, so that the distance between adjacent two tanks A conveyed to the filling mechanism is equal, which is convenient for the pressing mechanism 4 to press the tank A. The pressing mechanism 4 is connected to the linear conveying mechanism 2 and can press down the activated carbon layer in the tank A to prevent partial mixing of the catalyst and the activated carbon due to the vibration of the tank A caused by the operation of the linear conveying mechanism 2, thereby ensuring the gas filtering effect of the finished gas filtering tank.

[0036] During use, place the tank A on the circular conveying mechanism 1, and the circular conveying mechanism 1 conveys the tank A to the linear conveying mechanism 2. During the conveying process, the intermittent feeding mechanism 3 feeds the tank A at intervals, so that multiple tanks A are conveyed to the filling mechanism at equal intervals. After the linear conveying mechanism 2 conveys the tank A to the filling mechanism, the circular conveying mechanism 1, the linear conveying mechanism 2 and the intermittent feeding mechanism 3 stop running. The filling mechanism sequentially lays a catalyst layer, a second filter cloth and an activated carbon layer in the tank A. Then start the pressing mechanism 4, and the pressing mechanism 4 presses down the activated carbon layer. Then start the circular conveying mechanism 1, the linear conveying mechanism 2 and the intermittent feeding mechanism 3 again, so that the filled tank A continues to move, and the pressing mechanism 4 continuously presses down the activated carbon layer in the tank A until the tank A moves to the end of the linear conveying mechanism 2.

[0037] As Figure 1 and Figure 2 As shown in the figure, the linear conveying mechanism 2 includes a mounting frame 21 and a conveying member 22. The conveying member 22 is installed in the mounting frame 21. The conveying member 22 is composed of a motor, a conveyor belt and two conveying rollers. The two conveying rollers are respectively rotatably connected to the front and rear ends of the inner side of the mounting frame 21. The conveyor belt is drivingly connected between the two conveying rollers. The motor is connected to the mounting frame 21, and the output shaft of the motor is connected to one of the conveying rollers. The circular conveying mechanism 1 conveys the tank A to the conveyor belt, starts the motor to drive the transmission between the conveyor belt and the two conveying rollers, and drives the tank A to move to the filling mechanism through the conveyor belt.

[0038] As Figures 1 to 3As shown, the interval discharge mechanism 3 includes a driving source 31, a partition 32 and a pushing part 33. The driving source 31 is connected to the mounting frame 21 and is close to the circular conveying mechanism 1. The partition 32 is inserted into the mounting frame 21. A vertical slide groove is provided on the side of the partition 32. The pushing part 33 is connected to the output shaft of the driving source 31. A circular protrusion is provided on the pushing part 33, and the circular protrusion is slidably connected in the slide groove on the partition 32. The driving source 31 is started to drive the pushing part 33 to rotate. The circular protrusion on the pushing part 33 can push the partition 32 close to or away from the tank body A, thereby realizing equidistant discharge of the tank body A.

[0039] like Figure 1 , Figures 4 to 9 As shown, the pressing mechanism 4 includes a shell 41, a transmission member 42, a pressing member 43, a support member 44, a driving member 45 and a guide portion 46. The shell 41 is connected to the mounting frame 21, the transmission member 42 is installed in the shell 41, and the pressing member 43 is provided in plurality. The plurality of pressing members 43 are all connected to the transmission member 42. The transmission member 42 can drive the plurality of pressing members 43 to move along a set trajectory, and press down the activated carbon layer in the tank body A after the filling is completed one by one, so as to avoid partial mixing of the catalyst and the activated carbon due to the vibration of the tank body A during the operation of the linear conveying mechanism 2, thereby ensuring the gas filtering effect of the finished gas filter tank, and when the linear conveying mechanism 2 drives the tank body A When continuing to move, the transmission member 42 drives the pressing member 43 pressing down on the tank body A to move, so that the pressing member 43 can maintain the pressing state on the tank body A. The support member 44 is connected in the shell 41, and is used to support the pressing member 43 to ensure the stability of the pressing member 43 when in use. The driving member 45 is connected to the shell 41, and the driving member 45 is used to drive the pressing member 43 to press down the activated carbon layer in the tank body A. The guide part 46 is connected to the shell 41, and is used to gradually separate the pressing member 43 from the tank body A when the pressing member 43 moves to the end of the linear conveying mechanism 2, so as to avoid the negative pressure caused by the rapid resetting of the pressing member 43 and bring out part of the activated carbon in the tank body A.

[0040] Continue to refer Figure 1 , Figures 4 to 9 As shown, a side panel 411 is provided in the shell 41, an opening 412 is provided on the outer side of the shell 41, the transmission member 42 includes a transmission belt 422, a driving source 423 and two transmission rollers 421, the two transmission rollers 421 are respectively rotatably connected to the two ends of the inner side of the shell 41, the transmission belt 422 is transmission-connected between the two transmission rollers 421, the driving source 423 is connected to the shell 41, the driving source 423 is a motor, and the output shaft of the driving source 423 is connected to one of the transmission rollers 421, and multiple pressing members 43 are all connected to the outer side of the transmission belt 422. When the transmission belt 422 is running, it can drive the multiple pressing members 43 to move synchronously, so that the multiple pressing members 43 press down the tank body A after filling one by one.

[0041] Continue to refer to Figure 1 、 Figures 4 to 9 As shown, the pressing member 43 includes a first channel 431, a second channel 432, a pressing portion 433, a first elastic portion 434, a piston 435, and a second elastic portion 436. The first channel 431 is connected to the outside of the conveyor belt 422. The second channel 432 is inserted into one end of the first channel 431 close to the linear conveying mechanism 2. The pressing portion 433 is inserted into the second channel 432. The first elastic portion 434 is connected between the pressing portion 433 and the second channel 432. The first elastic portion 434 is a compression spring for driving the pressing portion 433 to reset. The piston 435 is inserted into one end of the first channel 431 away from the linear conveying mechanism 2. The second elastic portion 436 is connected between the piston 435 and the first channel 431. The second elastic portion 436 is a compression spring for driving the piston 435 to reset.

[0042] Start the driving member 45 to push the piston 435 to move in the direction of extending into the first channel 431 and compress the second elastic portion 436. At this time, through the air pressure inside the first channel 431, the second channel 432 and the pressing portion 433 are pushed to move. And under the action of the first elastic portion 434, the pressing portion 433 will not move downward. After the pressing portion 433 moves to directly above the can body A after filling, the second channel 432 stops moving under the limitation of the first channel 431. At this time, the piston 435 continues to move in the direction of extending into the first channel 431, and can push the pressing portion 433 to move downward into the can body A under the action of air pressure, and press the activated carbon layer in the can body A to avoid partial mixing of the catalyst and the activated carbon due to the vibration of the can body A during the operation of the linear conveying mechanism 2, thereby ensuring the air filtering effect of the finished air filter can.

[0043] When the linear conveying mechanism 2 drives the filled can body A to continue to move, start the transmission member 42 to drive the pressing member 43 to move synchronously with the can body A, so that the piston 435 on the pressing member 43 moves to the side plate surface 411 of the housing 41. The piston 435 is blocked and positioned by the side plate surface 411, so that the pressing portion 433 remains in the state of pressing the activated carbon layer in the can body A under the action of air pressure. After the piston 435 is separated from the side plate surface 411, the piston 435 resets under the action of the second elastic portion 436. At the same time, under the action of the first elastic portion 434, the pressing portion 433 first disengages from the can body A, and then the second channel 432 drives the pressing portion 433 to move away from the top of the can body A and reset.

[0044] Continue to refer to Figure 1 、 Figures 4 to 9As shown, the support member 44 includes a guide rail 441 and a rolling structure. The guide rail 441 is connected inside the housing 41. The rolling structure is provided in multiple groups, and the multiple groups of rolling structures are respectively connected to a plurality of first channels 431. The rolling structure includes a connecting portion 442 and three rotating portions 443. The connecting portion 442 is connected to the first channel 431, and the three rotating portions 443 are all rotatably connected to the connecting portion 442. The three rotating portions 443 are arranged in a triangle, and the three rotating portions 443 are all in rolling contact with the guide rail 441, so as to realize the limitation of the first channel 431.

[0045] When the piston 435 moves in the first channel 431, the first channel 431 is supported and limited by the support member 44 to prevent the connection between the first channel 431 and the transmission belt 422 from being damaged. When the transmission belt 422 drives the first channel 431 to move, it can drive the connecting portion 442 and the three rotating portions 443 at its bottom to move, and make the three rotating portions 443 roll on the guide rail 441.

[0046] Continue to refer to Figure 1 、 Figures 4 to 9 As shown, the driving member 45 includes a telescopic portion 451 and a push plate 452. The telescopic portion 451 is connected to the housing 41. The telescopic portion 451 is a cylinder. The push plate 452 is connected to the telescopic end of the telescopic portion 451. Starting the telescopic portion 451 drives the push plate 452 to approach the housing 41, and the telescopic portion 451 pushes the piston 435 to move in the direction of extending into the first channel 431 until the end face of the piston 435 is in the same plane as the side plate surface 411, so as to drive the pressing portion 433 to press the activated carbon layer in the tank body A under the action of air pressure. The guiding portion 46 is connected in the opening 412. The guiding portion 46 is inclined. When the tank body A moves to the end of the linear conveying mechanism 2, the piston 435 on the corresponding pressing member 43 contacts the guiding portion 46. At this time, the piston 435 is driven by the second elastic portion 436 to reset, and gradually resets under the guiding of the guiding portion 46, so as to prevent part of the activated carbon in the tank body A from being carried out due to the rapid reset of the pressing portion 433 generating negative pressure.

[0047] Working principle:

[0048] Place a plurality of tank bodies A on the circular conveying mechanism 1, and the circular conveying mechanism 1 conveys the tank bodies A to the linear conveying mechanism 2.

[0049] Start the driving source one 31 to drive the pushing portion 33 to rotate, and push the separating portion 32 to approach or move away from the tank body A through the circular protrusion on the pushing portion 33, so as to equally space the tank bodies A for discharging materials.

[0050] After the linear conveying mechanism 2 drives the tank body A to move to the filling mechanism, the circular conveying mechanism 1, the linear conveying mechanism 2 and the intermittent feeding mechanism 3 stop operating. The filling mechanism sequentially lays the catalyst layer, the second filter cloth and the activated carbon layer in the tank body A layer by layer. Subsequently, the telescopic part 451 is started to drive the push plate 452 to approach the housing 41, and the telescopic part 451 pushes the piston 435 to move in the direction of extending into the first channel 431 until the end face of the piston 435 and the side plate surface 411 are in the same plane.

[0051] When the piston 435 moves in the direction of extending into the first channel 431, the second elastic part 436 is compressed. At this time, through the air pressure inside the first channel 431, the second channel 432 and the pressing part 433 are pushed to move. And under the action of the first elastic part 434, the pressing part 433 will not move downward. After the pressing part 433 moves to directly above the tank body A after filling, the second channel 432 stops moving under the limitation of the first channel 431. At this time, the piston 435 continues to move in the direction of extending into the first channel 431, and under the action of the air pressure, the pressing part 433 is pushed to move downward into the tank body A and press the activated carbon layer in the tank body A, and the first channel 431 is supported and limited by the support member 44.

[0052] When the linear conveying mechanism 2 drives the filled tank body A to continue moving, the transmission part 42 is started to drive the pressing part 43 to move synchronously with the tank body A, so that the piston 435 on the pressing part 43 moves to the side plate surface 411 of the housing 41, and the piston 435 is blocked and positioned by the side plate surface 411, so that the pressing part 433 remains in the state of pressing the activated carbon layer in the tank body A under the action of the air pressure. At the same time, the connecting part 442 and the three rotating parts 443 at the bottom of its first channel 431 are driven to move, and the three rotating parts 443 roll on the guide rail 441.

[0053] When the tank body A moves to the end of the linear conveying mechanism 2, the piston 435 on the corresponding pressing part 43 contacts the guiding part 46. At this time, the piston 435 is driven by the second elastic part 436 to reset, and gradually resets under the guiding of the guiding part 46. At the same time, under the action of the first elastic part 434, the pressing part 433 first disengages from the tank body A, and then the second channel 432 drives the pressing part 433 to move away from the top of the tank body A and reset.

[0054] Finally, the filled tank body A is taken down and subsequent packaging can be carried out.
