Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of automatic control production lines, and particularly to an anti-blocking instrument blowing system. Background Art
[0002] A packaging production line is a general term for a system. Generally, a production manufacturer has its own packaging production line, which is generally composed of several different packaging machines and conveyor belts. Products in production or products that have been processed are transported to the packaging production line for packaging and processing, and after completion, they are sent out to become complete products that are convenient for transportation.
[0003] The packaging production line is an automatic control production line, and there are control probes such as proximity switches on the production line. These control probes are easily damaged when they come into contact with dust, resulting in production stoppage. In addition, the batch number needs to be sprayed on the rear side of the packaged paper bag. Generally, an automatic inkjet printer is used. After using it for a period of time, the dust adhered to the paper bag will block the nozzle of the inkjet printer, and the later rework will waste manpower and material resources. Content of the Utility Model
[0004] The utility model provides an anti-blocking instrument blowing system.
[0005] The technical solution of the utility model is as follows: an anti-blocking instrument blowing system, including an instrument air device and an electromagnetic valve. One side of the instrument air device is provided with an air pipe, and the other side of the instrument air device is provided with a three-way pipe. The two ends of the three-way pipe far away from the instrument air device are respectively provided with a connecting pipe A and a connecting pipe B. The end of the connecting pipe B far away from the three-way pipe is connected to the electromagnetic valve. A sensor is arranged on the side of the electromagnetic valve, and a pipeline is arranged at the bottom of the electromagnetic valve. An air outlet head is arranged at the bottom of the instrument air device, and a protection mechanism is arranged at the bottom of the air outlet head.
[0006] The sensor is electrically connected to the electromagnetic valve through an internal wire, and an installation bracket is arranged at the top of the instrument air device.
[0007] The protection mechanism includes a protective sleeve, which is sleeved on the surface of the air outlet head. A groove is opened inside the protective sleeve, a torsion spring is arranged inside the groove, a rotating shaft is rotatably connected inside the groove through the torsion spring, a sealing cover is fixedly connected to the bottom of the rotating shaft, a clamping groove is opened at the top of the sealing cover, a magnet is fixedly connected to the bottom inside the clamping groove, a connecting rod is fixedly connected to the side of the protective sleeve, a groove is opened at the end of the connecting rod far away from the protective sleeve, a telescopic spring is arranged inside the groove, a clamping block is slidably connected inside the groove through the telescopic spring, a pull rod is fixedly connected to the top of the clamping block, and the pull rod penetrates and is slidably connected to the connecting rod.
[0008] The bottom of the protective cover is closely attached to the top of the closing cover, and the diameter of the closing cover is equal to that of the protective cover. When the closing cover rotates to directly below the protective cover, it will close the opening at the bottom of the protective cover.
[0009] In its initial state, the torsion spring is in a tense state. When the torsion spring rebounds, it will drive the closing cover to rotate to directly below the protective cover.
[0010] The opening size of the groove is equal to that of the card slot, and the card block can be inserted into the card slot.
[0011] In its initial state, half of the card block is located in the card slot. Inserting the card block into the card slot can fix the position of the closing cover.
[0012] The material of the card block is ferromagnetic stainless steel, and the bottom of the card block is initially adsorbed to the bottom of the magnet. The magnet can adsorb the card block to make it move downward.
[0013] In its initial state, the telescopic spring is in a stretched state. When the telescopic spring rebounds, it will drive the card block to completely retract into the groove.
[0014] The magnetic force of the magnet is greater than the elastic force of the telescopic spring.
[0015] The working principle and beneficial effects of the present utility model are as follows:
[0016] 1. By providing an instrument air device, the present utility model adds an instrument air purging step beside the control probe on the packaging production line. By purging the control probe with instrument air at irregular intervals, the packaging stop caused by probe failure is reduced. At the same time, instrument air purging can also be added beside the inkjet printer nozzle to improve the problem that the inkjet printer nozzle is always blocked. In order to prevent waste caused by the continuous opening of the instrument air, solenoid valve control is added to the instrument purging at the above two places. Air blowing only occurs when the packaging bag passes by and is closed at other times. This not only solves the system stop caused by dust but also reduces the waste of instrument air.
[0017] 2. By providing a protection mechanism, when the instrument air device is not used for a long time, the present utility model can pull up the pull rod upward. At this time, the closing cover will automatically rotate to directly below the protective cover to close the opening, preventing other sundries from entering and blocking the air outlet head during long-term static placement. When the closing cover is rotated again to open the opening at the bottom of the protective cover, the card block will automatically be inserted into the card slot to fix the position of the closing cover, effectively achieving a protective effect.

[0025] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.
[0026] Embodiment 1
[0027] As Figures 1 to 2 shown, this embodiment proposes an anti-blocking instrument blowing system, including an instrument air device 1 and a solenoid valve 6. One side of the instrument air device 1 is provided with an air pipe 2, and the other side of the instrument air device 1 is provided with a three-way pipe 3. The two ends of the three-way pipe 3 away from the instrument air device 1 are respectively provided with a connecting pipe A 4 and a connecting pipe B 5. One end of the connecting pipe B 5 away from the three-way pipe 3 is connected to the solenoid valve 6. A sensor 7 is provided on the side of the solenoid valve 6. The sensor 7 is electrically connected to the solenoid valve 6 through an internal wire. An installation bracket is provided on the top of the instrument air device 1. A pipeline 8 is provided at the bottom of the solenoid valve 6. An air outlet head 9 is provided at the bottom of the instrument air device 1. A protection mechanism 10 is provided at the bottom of the air outlet head 9.
[0028] In this embodiment, two sets of overall devices are respectively installed beside the control probe on the packaging production line and beside the nozzle of the inkjet printer. The air pipe 2, the connecting pipe A 4, the connecting pipe B 5 and the pipeline 8 are connected to the corresponding pipelines. The air outlet head 9 sprays out gas, and periodically blows the instrument air to the control probe and the nozzle of the inkjet printer. Moreover, the instrument blowing at the above two places is controlled by the solenoid valve 6, and the air blowing is only carried out when the packaging bag passes by and is closed at other times. In this way, both the system stop caused by dust is solved and the waste of instrument air is reduced.
[0029] Embodiment 2
[0030] As Figures 3 to 5 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes a protection mechanism 10, including a protective sleeve 101. The protective sleeve 101 is sleeved on the surface of the air outlet head 9. A groove body 102 is opened inside the protective sleeve 101. A torsion spring 103 is arranged inside the groove body 102. A rotating shaft 104 is rotatably connected inside the groove body 102 through the torsion spring 103. The torsion spring 103 is in a taut state in the initial state. When the torsion spring 103 rebounds, it will drive the closing cover 105 to rotate to directly below the protective sleeve 101. The bottom of the rotating shaft 104 is fixedly connected with the closing cover 105. The bottom of the protective sleeve 101 is closely attached to the top of the closing cover 105, and the diameter of the closing cover 105 is equal to the diameter of the protective sleeve 101. When the closing cover 105 rotates to directly below the protective sleeve 101, it will close the opening below the protective sleeve 101. A clamping groove 106 is opened at the top of the closing cover 105. A magnet 107 is fixedly connected to the inner bottom of the clamping groove 106. A connecting rod 108 is fixedly connected to the side surface of the protective sleeve 101. A groove 109 is opened at one end of the connecting rod 108 away from the protective sleeve 101. The opening size of the groove 109 is equal to the opening size of the clamping groove 106. A clamping block 1011 can be inserted into the clamping groove 106. A telescopic spring 1010 is arranged inside the groove 109. The telescopic spring 1010 is in a stretched state in the initial state. When the telescopic spring 1010 rebounds, it will drive the clamping block 1011 to completely retract into the groove 109. The clamping block 1011 is slidably connected inside the groove 109 through the telescopic spring 1010. Initially, half of the clamping block 1011 is located inside the clamping groove 106. When the clamping block 1011 is inserted into the clamping groove 106, the position of the closing cover 105 can be fixed. The material of the clamping block 1011 is ferromagnetic stainless steel, and the bottom of the clamping block 1011 is initially adsorbed to the bottom of the magnet 107. The magnet 107 can adsorb the clamping block 1011 to make it move downward. The magnetic force of the magnet 107 is greater than the elastic force of the telescopic spring 1010. The top of the clamping block 1011 is fixedly connected with a pull rod 1012. The pull rod 1012 penetrates through and is slidably connected with the connecting rod 108.
[0031] In this embodiment, when the instrument air device 1 is not used for a long time, pull the pull rod 1012 upward. The upward movement of the pull rod 1012 drives the clamping block 1011 to move upward and leave the clamping groove 106 and return to the groove 109. When the clamping block 1011 leaves the clamping groove 106, the torsion spring 103 will rebound and drive the rotating shaft 104 to rotate. The rotation of the rotating shaft 104 drives the closing cover 105 to rotate to directly below the protective sleeve 101 to close the bottom opening of the protective sleeve 101, preventing other sundries from entering and blocking the air outlet head 9 during long-term static state. When it is reused, rotate the closing cover 105 in the reverse direction to make it rotate to the far right to open the opening below the protective sleeve 101. At this time, the groove 109 fits with the clamping groove 106, and the magnetic force of the magnet 107 will drive the clamping block 1011 to move downward and re-enter the clamping groove 106 to fix the position of the closing cover 105.
[0032] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
