Description

Technical Field

[0001] This utility model belongs to the field of cover-making machines, specifically relating to an air-blowing mechanism for cover-making machines. Background Technology

[0002] A capping machine is an automated device specifically designed for sealing containers such as plastic bottles and food cans.

[0003] In the production and packaging line of veterinary drugs (tilmicosin or florfenicol), the capping machine is one of the key pieces of equipment.

[0004] The capping machine currently used in our factory mainly uses a mechanical structure to guide the bottle caps to slide down the capping channel. However, in actual use, this mechanical structure often causes jamming due to the bottle caps not sliding down in time, resulting in poor cap conveying. If workers do not notice this in time, prolonged jamming can easily damage the baffles on the conveyor belt, affecting production.

[0005] Therefore, we propose an air-blowing mechanism for a top cover machine to solve the above problems. Utility Model Content

[0006] The capping machine currently used in our factory mainly uses a mechanical structure to guide the bottle caps to slide down the capping channel. However, in actual use, this mechanical structure often causes jamming due to the bottle caps not sliding down in time, resulting in poor cap delivery. This utility model provides an air blowing mechanism for the capping machine.

[0007] The solution adopted by this utility model to solve its technical problem is: a gas blowing mechanism for a cover-making machine, including an air supply pipe, a solenoid valve, a gas throttle valve, a bamboo-joint nozzle, a photoelectric sensor, and a gas storage tank for storing high-pressure gas. The gas outlet of the gas storage tank is connected to the solenoid valve through the air supply pipe. A connecting air pipe is installed between the solenoid valve and the gas throttle valve. The solenoid valve and the gas throttle valve are respectively installed on the outer side of the cover conveyor.

[0008] The outlet end of the gas throttle valve is equipped with an outlet pipe, and the end of the outlet pipe is equipped with a bamboo tube nozzle. The bamboo tube nozzle corresponds to the cap outlet channel of the cap conveyor and is used to blow the bottle cap to the cap outlet channel.

[0009] A photoelectric sensor is installed on the cap conveyor and located below the bamboo tube nozzle to detect the position of the bottle cap on the cap conveyor.

[0010] Preferably, the solenoid valve is a normally closed solenoid valve.

[0011] Preferably, the gas throttle valve is a manually adjustable throttle valve.

[0012] Preferably, the tail end of the bamboo-joint nozzle is fitted with a fixing seat, which is mounted on the cover conveyor.

[0013] Preferably, the gas storage tank is made of stainless steel and has a volume of 50L.

[0014] Preferably, the air supply pipe, connecting pipe, and outlet pipe are all high-pressure resistant hoses.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses a photoelectric sensor to detect the position of the bottle cap in real time and links it with a solenoid valve. When the solenoid valve receives a signal, it opens. The high-pressure gas in the gas tank passes through the gas supply pipe, solenoid valve, connecting gas pipe, gas throttle valve and gas outlet pipe to the bamboo tube nozzle. The gas blown out by the bamboo tube nozzle blows the bottle cap to the cap outlet channel, ensuring the normal operation of the capping machine and avoiding the occurrence of bottle cap jamming.

[0017] 2. This utility model adopts a manually adjustable gas throttle valve, which allows operators to flexibly adjust the gas flow rate according to actual production needs, ensuring that the force of the bottle cap blowing is moderate and adaptable to bottle caps of different specifications and weights.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1 This utility model provides a technical solution for an air blowing mechanism for a top cover machine:

[0022] Example 1:

[0023] according to Figure 1 As shown, it includes a gas supply pipe 4, a solenoid valve 2, a gas throttle valve 3, a bamboo-joint nozzle 7, a photoelectric sensor 8, and a gas storage tank 1 for storing high-pressure gas. The gas storage tank 1 is equipped with a pressure gauge and a pressure relief valve to ensure safe operation. The gas storage tank 1 is made of stainless steel and has a volume of 50L. The gas storage tank 1 has high pressure resistance and corrosion resistance to ensure that the high-pressure gas remains stable during long-term, high-frequency use.

[0024] The outlet of the gas storage tank 1 is connected to the solenoid valve 2 through the gas supply pipe 4. The solenoid valve 2 is a normally closed solenoid valve 2, which opens when it receives a signal from the control system. The gas throttle valve 3 is a manually adjustable throttle valve, which can adjust the gas flow according to actual needs to ensure that the force of the bottle cap blowing is moderate and adaptable to bottle caps of different specifications and weights. A connecting gas pipe 10 is installed between the solenoid valve 2 and the gas throttle valve 3. The solenoid valve 2 and the gas throttle valve 3 are respectively installed on the outer side of the cap conveyor 92.

[0025] The outlet end of the gas throttle valve 3 is equipped with an outlet pipe 5, and the end of the outlet pipe 5 is equipped with a bamboo tube nozzle 7. The tail end of the bamboo tube nozzle 7 is fitted with a fixing seat 6. The fixing seat 6 is installed on the cap conveyor 92 and is located between the cap conveyor 92 and the transparent cover plate 94. The bamboo tube nozzle 7 corresponds to the cap outlet channel of the cap conveyor 92. When the solenoid valve 2 is opened, the high-pressure gas in the gas storage tank 1 reaches the bamboo tube nozzle 7 through the gas supply pipe 4, solenoid valve 2, connecting gas pipe 10, gas throttle valve 3 and outlet pipe 5. The bamboo tube nozzle 7 blows out gas to blow the bottle cap to the cap outlet channel, ensuring the normal operation of the capping machine and avoiding the occurrence of bottle cap jamming.

[0026] The photoelectric sensor 8 is installed on the cap conveyor 92 and located below the bamboo tube nozzle 7. It is used to detect the position of the bottle cap on the cap conveyor 92. Under the coordination of the control system, the photoelectric sensor 8 is linked with the solenoid valve 2, so that the solenoid valve 2 can open or close according to the received signal to realize automated operation.

[0027] In this embodiment, the air supply pipe 4, the connecting air pipe 10, and the air outlet pipe 5 are all high-pressure resistant hoses, which have good flexibility and pressure resistance, and are easy to install and arrange.

[0028] In practical use, the air blowing mechanism for a capping machine of this utility model first adjusts the blowing angle of the bamboo tube nozzle 7 so that the bamboo tube nozzle 7 corresponds to the cap outlet channel of the cap conveyor 92. Then, the gas throttle valve 3 is adjusted according to the weight of the bottle cap to ensure that the blowing force of the bottle cap is moderate.

[0029] When the cap conveyor 92 conveys the bottle cap to the detection position of the photoelectric sensor 8, the photoelectric sensor 8 detects the bottle cap and transmits a signal to the control system. The control system then transmits the signal to the solenoid valve 2, causing the solenoid valve 2 to open.

[0030] At this time, the high-pressure gas in the gas storage tank 1 reaches the bamboo tube nozzle 7 through the gas supply pipe 4, solenoid valve 2, connecting gas pipe 10, gas throttle valve 3 and gas outlet pipe 5. The gas blown out by the bamboo tube nozzle 7 blows the bottle cap to the cap outlet channel.

[0031] After the blowing is completed, solenoid valve 2 is temporarily closed, waiting for the next bottle cap.
