Description

Technical Field

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

[0002] The fire escape mask is an escape equipment for sudden fires, in which the gas filter tank is an important component of the fire escape mask. When assembling the gas filter tank, usually the filter cloth one is laid in the tank body first, and the tank body laid with the filter cloth one is placed on the conveying device. After the tank body is transported to the filling mechanism by the conveying device, the operation of the conveying device is stopped, and then the filling mechanism lays the catalyst layer, the filter cloth two and the activated carbon layer in the tank body in layers, and finally the filled tank body is transported backward and removed, and finally the tank body is packaged by the packaging mechanism to assemble to form the gas filter tank.

[0003] A Chinese patent document with announcement number CN113979094B discloses a tank lane separation mechanism, including a tank lane execution general module, a tank body detection device, a transmission device, and a track module. The tank lane execution general module includes a tank blocking following component, a total tank blocking mechanism, double-sided fixing plates, and a tank body shifting general 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 shifting general component is located above the transmission device and is arranged on one side of the total tank blocking mechanism, and the tank body detection device is arranged on the transmission device.

[0004] In the existing tank lane separation mechanism, when the production line is started for the first time, the tanks move in a row from the middle of the track, the tank-blocking following component is in the tank-blocking state, the tank-blocking mechanism at the following end is in the tank-blocking state, and the tank-blocking mechanism at the shifting end is in the releasing state. The equipment starts to run, and the tanks will run in sequence. The tank detection board detects that there are tanks, and the detection device at the tank inlet end detects that there are tanks for a period of time. At the same time, the tank-blocking following component is in place and there are no tanks. At this time, a signal is sent to make the front tank body shifting component and the rear tank body shifting component move synchronously. , move the cans to the required channel, follow the end can blocking mechanism to open the cans, and at the same time, the shift end can blocking mechanism blocks the rear cans, allowing the cans to run continuously. After the cans are output, the can blocking components of the following components will align the cans during operation, and then the can blocking components of the following components will be lifted up by the telescopic mechanism of the following components, releasing the sorted cans to prepare for the back, and then a new cycle will be carried out. The front tank body shifting components and the rear tank body shifting components will act at the same time, and while completing the action, there is a track channel to accommodate new cans.

[0005] However, the above-mentioned prior art still has the following shortcomings: after the catalyst layer, the second filter cloth and the activated carbon layer are laid in the tank body in sequence, 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 body is continued to be driven by the conveying device to move, the tank body is easily vibrated by the influence of the operation of the conveying device, and the catalyst layer or the activated carbon layer passes through the second filter cloth, thereby causing partial mixing of the catalyst and the activated carbon, which in turn affects the air filtering effect of the air filter tank. Summary of the invention

[0006] The present invention provides a tank feeding device for respirator production, aiming to solve the problem in the related art that when a conveying device conveys the tank, the tank vibrates, resulting in partial mixing of catalyst and 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 body, and also includes a pressing mechanism, which includes a transmission member and a plurality of pressing members, the transmission member is connected to the linear conveying mechanism, the transmission member can drive the pressing member and the tank body to move synchronously, the plurality of pressing members are all connected to the transmission member, and the tank body is filled with a catalyst layer, a filter cloth second and an activated carbon layer in sequence; the pressing member includes a channel one and a pressing part, the pressing part is arranged on the channel one, and air pressure is applied to the channel one, and the air pressure can drive the pressing part to move into the tank body and press down the activated carbon layer in the tank body.

[0008] Beneficial effect: the tank body is transported from the circular conveying mechanism to the linear conveying mechanism, and then transported by the linear conveying mechanism to the filling mechanism, and the catalyst layer, the second filter cloth and the activated carbon layer are sequentially transported into the tank body by the filling mechanism. After the filling is completed, air pressure is applied to the channel one, so that the air pressure inside the channel one increases, at this time, the pressing part can be driven downward by the air pressure until the pressing part moves into the tank body, and at the same time, the activated carbon layer in the tank body is squeezed by the pressing part, so that the catalyst layer, the second filter cloth and the activated carbon layer are in close contact in sequence, after the activated carbon layer in the tank body is pressed downward, when the tank body containing the catalyst layer, the second filter cloth and the activated carbon layer is driven to continue to move by the linear conveying mechanism, the pressing part extending into the tank body is driven to move synchronously by the transmission member, so that the pressing part on the pressing part moves synchronously with the tank body, so as to avoid partial mixing of the catalyst and the activated carbon due to the vibration of the tank body when the linear conveying mechanism is running, thereby ensuring the gas filtering effect of the finished gas filter tank.

[0009] Preferably, the pressing member further comprises channel 2, elastic part 1, piston and elastic part 2, channel 2 is plugged into one end of channel 1, the piston is plugged into the other end of channel 1, the pressing part is plugged into channel 2, elastic part 1 is connected between channel 2 and the pressing part, and elastic part 2 is connected between the piston and channel 1. The effect is that when the piston moves toward channel 1, it can push channel 2 to move under the action of air pressure, thereby driving the pressing part to move to the top of the tank body, and after channel 2 is blocked by channel 1 and stops moving, the piston continues to move, and can push the pressing part down into the tank body through air pressure, thereby providing power for the pressing part to press down the activated carbon layer in the tank body.

[0010] Preferably, the pressing mechanism further comprises a housing, and the transmission member is installed in the housing, which has the effect 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 rotatably connected in the housing, the transmission belt is transmission-connected between the two transmission rollers, and the channel 1 is connected to the transmission belt. The effect is that the transmission between the transmission belt and the two transmission rollers can provide power for the movement of the lower pressing member.

[0012] Preferably, the pressing mechanism further comprises a support member, the support member comprises a guide rail and a plurality of rolling structures, the guide rail is connected in the housing, the plurality of rolling structures are respectively connected to a plurality of channels 1, the rolling structure comprises a connecting portion and three rotating portions, the connecting portion is connected to the channel 1, the three rotating portions are all rotatably connected to the connecting portion, and the three rotating portions are all in rolling contact with the guide rail. The effect is that when air pressure is applied to the channel 1, the channel 1 is supported and limited by the support member to avoid damage to the connection between the channel 1 and the transmission belt.

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

[0014] Preferably, a side panel is provided inside the shell, and an opening is provided on the outer side of the shell.

[0015] Preferably, the material pressing mechanism further comprises a driving member, the driving member comprises 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 surface of the piston and the side plate surface are located in the same plane, so that after the piston is separated from the push plate, the side plate surface is used to block and position the piston, so that the pressing part can still keep pressing down the activated carbon layer in the tank under the action of air pressure.

[0016] Preferably, the pressing mechanism further comprises a guide part, which is connected to the housing and is inclined. The effect is that when the tank moves to the end of the linear conveying mechanism, the piston on the corresponding pressing member contacts the guide part, and the piston is driven by the second elastic part and gradually resets under the guidance of the guide part, so as to avoid negative pressure caused by the rapid reset of the pressing part and bring out part of the activated carbon in the tank.

[0017] Preferably, the device further comprises an interval discharging mechanism, which is connected to the linear conveying mechanism and comprises a partition inserted into the linear conveying mechanism, and the partition can be close to or away from the tank body. The effect is that the tank body can be discharged at equal distances by moving the tank body.

[0018] The beneficial effects of the present invention are: 1. The driving member pushes the piston toward the channel one and compresses the elastic part two until the end face of the piston is in the same plane as the side plate surface. At this time, the air pressure inside the channel one pushes the channel two and the pressing part to move, and under the action of the elastic part one, the pressing part will not move downward. After the pressing part moves to the top of the tank body after filling, the channel one limits the channel two, and the channel two stops moving. At this time, the piston continues to move in the direction of extending into the channel one, and can push the pressing part down into the tank body under the action of the air pressure, and press down the activated carbon layer in the tank body to avoid partial mixing of the catalyst and the activated carbon due to the vibration of the tank body during the operation of the linear conveying mechanism, thereby ensuring the gas filtering effect of the finished gas filter tank.

[0019] 2. When the piston moves in channel 1, channel 1 is supported and limited by the support member to avoid damage to the connection between channel 1 and the transmission belt.

[0020] 3. When the tank body moves to the end of the linear conveying mechanism, the piston on the corresponding pressing part contacts the guide part. At this time, the piston is driven by the elastic part 2 and gradually resets under the guidance of the guide part to avoid the negative pressure caused by the rapid reset of the pressing part and taking out part of the activated carbon in the tank body.

[0021] 4. The driving source drives the pushing part to rotate, and the circular protrusion on the pushing part can push the partition part to be close to or away from the tank body, thereby achieving equidistant discharge of the tank body. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] When in use, the tank body A is placed on the circular conveying mechanism 1, and the circular conveying mechanism 1 conveys the tank body A to the linear conveying mechanism 2. During the conveying process, the interval discharge mechanism 3 discharges the tank body A at intervals so that multiple tank bodies A are equidistantly conveyed to the filling mechanism. After the linear conveying mechanism 2 conveys the tank body A to the filling mechanism, the circular conveying mechanism 1, the linear conveying mechanism 2 and the interval discharge mechanism 3 stop running, and the filling mechanism sequentially lays the catalyst layer, the filter cloth 2 and the activated carbon layer in the tank body A in layers, and then starts the pressing mechanism 4, and the pressing mechanism 4 presses down the activated carbon layer, and then starts the circular conveying mechanism 1, the linear conveying mechanism 2 and the interval discharge mechanism 3 again, so that the filled tank body A continues to move, and the pressing mechanism 4 continues to press down the activated carbon layer in the tank body A until the tank body A moves to the end of the linear conveying mechanism 2.

[0035] like Figure 1 and Figure 2 As shown, 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 conveyor rollers. The two conveyor rollers are rotatably connected to the front and rear ends of the inner side of the mounting frame 21 respectively.

[0036] like 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.

[0037] 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.

[0038] 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.

[0039] Continue to refer Figure 1 , Figures 4 to 9 As shown, the pressing member 43 includes a channel 1 431, a channel 2 432, a pressing portion 433, an elastic portion 1 434, a piston 435 and an elastic portion 2 436. The channel 1 431 is connected to the outer side of the transmission belt 422. The channel 2 432 is inserted into the end of the channel 1 431 close to the linear conveying mechanism 2. The pressing portion 433 is inserted into the channel 2 432. The elastic portion 1 434 is connected between the pressing portion 433 and the channel 2 432. The elastic portion 1 434 is a compression spring for driving the pressing portion 433 to reset. The piston 435 is inserted into the end of the channel 1 431 away from the linear conveying mechanism 2. The elastic portion 2 436 is connected between the piston 435 and the channel 1 431. The elastic portion 2 436 is a compression spring for driving the piston 435 to reset.

[0040] The driving member 45 is started to push the piston 435 to move in the direction of the channel 1 431 and compress the elastic part 2 436. At this time, the air pressure inside the channel 1 431 pushes the channel 2 432 and the pressing part 433 to move, and under the action of the elastic part 1 434, the pressing part 433 will not move downward. After the pressing part 433 moves to the top of the tank body A after the filling is completed, the channel 2 432 stops moving under the limit of the channel 1 431. At this time, the piston 435 continues to move in the direction of the channel 1 431, and can push the pressing part 433 to move downward into the tank body A under the action of the air pressure, and press down the activated carbon layer in the tank body A 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 air filtering effect of the finished air filter tank.

[0041] When the linear conveying mechanism 2 drives the filled tank body A to continue to move, the transmission member 42 is started to drive the pressing member 43 to move synchronously with the tank body A, so that the piston 435 on the pressing member 43 moves to the side plate surface 411 of the shell 41, and the piston 435 is blocked and positioned by the side plate surface 411, so that the pressing part 433 can still keep pressing down the activated carbon layer in the tank body A under the action of air pressure. After the piston 435 is separated from the side plate surface 411, the piston 435 is reset under the action of the elastic part 436. At the same time, under the action of the elastic part 434, the pressing part 433 is first separated from the tank body A, and then the channel 432 drives the pressing part 433 to move away from the top of the tank body A and reset.

[0042] Continue to refer 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 in the shell 41, the rolling structure is arranged in multiple groups, the multiple groups of rolling structures are respectively connected to multiple channels 431, the rolling structure includes a connecting part 442 and three rotating parts 443, the connecting part 442 is connected to the channel 431, the three rotating parts 443 are all rotatably connected to the connecting part 442, the three rotating parts 443 are arranged in a triangle, and the three rotating parts 443 are all in rolling contact with the guide rail 441, thereby realizing the limitation of the channel 431.

[0043] When the piston 435 moves in the channel 1 431, the support member 44 supports and limits the channel 1 431 to avoid damage to the connection between the channel 1 431 and the transmission belt 422. When the transmission belt 422 drives the channel 1 431 to move, it can drive the connection part 442 and the three rotating parts 443 at the bottom thereof to move, and make the three rotating parts 443 roll on the guide rail 441.

[0044] Continue to refer 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 shell body 41, and the telescopic portion 451 is a cylinder. The push plate 452 is connected to the telescopic end of the telescopic portion 451. The telescopic portion 451 is started to drive the push plate 452 to approach the shell body 41, and the telescopic portion 451 pushes the piston 435 to move in the direction of extending into the channel 1 431 until the end surface of the piston 435 and the side plate surface 411 are located on the same plane, thereby driving the pressing portion 433 to press down the activated carbon layer in the tank body A under the action of air pressure. The guide portion 46 is connected in the opening 412, and the guide 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 guide portion 46. At this time, the piston 435 is reset by the elastic portion 2 436 and is gradually reset under the guidance of the guide portion 46 to avoid the negative pressure generated by the rapid reset of the pressing portion 433 and taking out part of the activated carbon in the tank body A.

[0045] Working principle: A plurality of can bodies A are placed on the circular conveying mechanism 1 , and the circular conveying mechanism 1 conveys the can bodies A to the linear conveying mechanism 2 .

[0046] The driving source 1 31 is started to drive the pushing part 33 to rotate, and the circular protrusion on the pushing part 33 pushes the partition part 32 to approach or move away from the tank body A, so that the tank body A is discharged at an equal distance.

[0047] 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 interval discharge mechanism 3 stop running, and the filling mechanism sequentially lays the catalyst layer, the second filter cloth and the activated carbon layer in the tank body A in layers, and then starts the telescopic part 451 to drive the push plate 452 to approach the shell 41, and the telescopic part 451 pushes the piston 435 to move in the direction of extending into the channel 1 431 until the end face of the piston 435 and the side plate surface 411 are on the same plane.

[0048] When the piston 435 moves in the direction of extending into the channel 1 431, the elastic part 2 436 is compressed. At this time, the air pressure inside the channel 1 431 pushes the channel 2 432 and the pressing part 433 to move, and under the action of the elastic part 1 434, the pressing part 433 will not move downward. After the pressing part 433 moves to the top of the tank body A after the filling is completed, the channel 2 432 stops moving under the limit of the channel 1 431. At this time, the piston 435 continues to move in the direction of extending into the channel 1 431, and under the action of the air pressure, the pressing part 433 is pushed down into the tank body A, and the activated carbon layer in the tank body A is pressed down, and the channel 1 431 is supported and limited by the support member 44.

[0049] When the linear conveying mechanism 2 drives the filled can body A to continue to move, the transmission member 42 is started 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 shell 41, and the piston 435 is blocked and positioned by the side plate surface 411, so that the pressing part 433 can still keep pressing down the activated carbon layer in the can body A under the action of air pressure, and at the same time drive the connecting part 442 and the three rotating parts 443 at the bottom of its channel 1 431 to move, and make the three rotating parts 443 roll on the guide rail 441.

[0050] When the tank body A moves to the end of the linear conveying mechanism 2, the piston 435 on the corresponding pressing piece 43 contacts the guide part 46. At this time, the piston 435 is reset by the elastic part 2 436 and gradually reset under the guidance of the guide part 46. At the same time, under the action of the elastic part 1 434, the pressing part 433 first separates from the tank body A, and then the channel 2 432 drives the pressing part 433 to move away from the top of the tank body A and reset.

[0051] Finally, the filled can body A is removed and the subsequent packaging is performed.
