Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing, in particular to an internal driving component of an electron gun. Background Art

[0002] Most of the current hot glue guns are pneumatic guns, which use solenoid valves to drive the needle valve to open and close the glue. The advantage of pneumatic guns is that they have strong adaptability to the viscosity of glue. When the viscosity is high, a higher air pressure is used to drive the needle valve. The disadvantage is that the action response frequency is low. If the glue application speed is slightly faster, the glue dispensing action cannot be performed. Due to the above-mentioned slow response defect, the effect of glue dispensing is line glue, rather than a clearly separated glue dispensing effect. The action response of some electronic guns for opening and closing glue can be completed in a limit of 2ms. They are generally used in cold glue (low viscosity). In the field of hot glue, there are limitations for high-viscosity hot glue, so it cannot meet the existing production needs.

[0025] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] like Figure 1 -7, the utility model provides an electron gun internal drive assembly 100 including a gun body 1, an adjusting rod 2, a coil assembly 3, an elastic member 4 and an ejector pin 5, the gun body 1 has a receiving chamber 11, the ejector pin 5 is slidably arranged at a liquid outlet 51 of the receiving chamber 11, the ejector pin 5 slides relative to the receiving chamber 11 to block the liquid outlet 51 or withdraw, the elastic member 4 is arranged on the ejector pin 5, the elastic member 4 is a compression spring, the elastic member 4 is connected to the outside of the ejector pin 5, the elastic member 4 provides an elastic force, and the elastic force makes one side of the ejector pin 5 always have a tendency to block the liquid outlet 51, the adjusting rod 2 is installed on the receiving chamber The coil assembly 3 is installed on the adjusting rod 2 in the cavity 11 and on the other side of the ejector pin 5. When the coil assembly 3 is energized, it attracts the ejector pin 5 so that the ejector pin 5 overcomes the elastic force of the elastic member 4 and moves away from the liquid outlet 51 and abuts against the adjusting rod 2. The adjusting rod 2 can control the retraction stroke of the ejector pin 5. The coordination among the adjusting rod 2, the coil assembly 3, the elastic member 4 and the ejector pin 5 makes the overall structure very simple. It can not only be flexibly used in cold glue guns and hot glue guns, but also has strong versatility. In addition, due to its simple and flexible structure, the ejector pin 5 is very flexible in movement and has the advantage of rapid response. More specifically, as follows:

[0027] like Figure 1-3, the adjusting rod 2 can move in the direction of approaching or moving away from the ejector pin 5, and an adjusting knob 6 is provided between the adjusting rod 2 and the gun body 1, and the adjusting knob 6 is connected to the adjusting rod 2. By rotating the adjusting knob 6, the distance between the ejector pin 5 and the adjusting rod 2 is adjusted, and the distance between the ejector pin 5 and the adjusting rod 2 is adjusted to zero to 0.4 cm. The manufacturer can adjust it according to actual needs, so it is not limited to this. Specifically, a digital mark 61 is provided on the adjusting knob 6, and an arrow mark 12 is provided on the gun body 1 corresponding to the digital mark 61. For example, there are multiple digital marks 61 such as 0, 0.1, 0.2, 0.3 and 0.4 on the adjusting knob 6, which respectively correspond to the distance between the ejector pin 5 and the adjusting rod 2. The retraction stroke of the ejector pin 5 is controlled by adjusting the distance, that is, the liquid output is controlled.

[0028] like Figure 7 The coil assembly 3 includes a coil seat 31 and a coil 32. The coil seat 31 is connected to the adjustment rod 2. The coil 32 is built into the coil seat 31. The coil seat 31 is a rectangular seat with a mounting cavity 311. The rectangular seat has a mounting port 312 and a lateral opening 313.

The sealing nozzle 8 is formed at the liquid outlet 51, and the sealing nozzle 8 is wrapped with the nozzle 9.

[0030] It is understandable that the electron gun internal drive assembly 100 of the present invention can be used on a cold glue gun and a hot glue gun, such as Figure 1 -3, when it is used in a cold glue gun, the cold glue gun includes a cold glue gun housing and an internal driving assembly 100 of the electron gun, and the gun body 1 is a cold glue gun body 1, and the cold glue gun body 1 is installed in the cold glue gun housing. A heat sink 3a is provided at the cold glue gun housing, and a heat sink 3a is provided on both sides of the coil assembly 3, which effectively ensures that the coil 32 is at room temperature and ensures the reliability of the cold glue. Figure 4 -7, when it is used in a hot glue gun, the hot glue gun includes a hot glue gun housing and an internal driving assembly 100 of the electron gun, and the gun body 1 is a hot glue gun body 1, and the hot glue gun body 1 is installed in the hot glue gun housing. The hot glue gun also includes a connecting piece for connecting to the outside, and a heat insulating piece 3b for heat insulation is provided between the connecting piece and the gun body 1, which ensures that the temperature is retained in the hot glue gun body 1 to the maximum extent, and does not affect the temperature conduction of the installation fixture to affect other equipment.

[0031] The working process of the electron gun internal drive assembly 100 of the utility model is as follows:

[0032] For example, cold glue guns, see Figures 1 to 3 When glue spraying is required, the glue flows from the glue flow channel into the adjusting rod 2 and the accommodating chamber 11, and flows to the sealing nozzle 8 and the nozzle 9. When the coil assembly 3 is energized, the ejector pin 5 is attracted, so that the ejector pin 5 overcomes the elastic force of the elastic member 4 and moves away from the liquid outlet 51 and abuts against the adjusting rod 2. The adjusting rod 2 controls the retraction amount of the ejector pin 5, that is, controls the liquid output amount, and the nozzle 9 sprays glue. When glue spraying is not required, when the coil assembly 3 is not energized, the ejector pin 5 abuts against the liquid outlet 51 and blocks it under the elastic recovery effect of the elastic member 4. At this time, the glue cannot be sprayed out (the flow path of the glue can be seen in Figure 3 in the direction indicated by arrow a).

[0033] By combining the gun body 1, the adjusting rod 2, the coil assembly 3, the elastic member 4 and the ejector pin 5 together, the gun body 1 has a accommodating chamber 11, the ejector pin 5 is slidably arranged at the liquid outlet 51 of the accommodating chamber 11, the elastic member 4 is arranged on the ejector pin 5, the elastic member 4 provides an elastic force, and the elastic force makes one side of the ejector pin 5 always have a tendency to block the liquid outlet 51, the adjusting rod 2 is installed in the accommodating chamber 11 and is located on the other side of the ejector pin 5, the coil assembly 3 is installed on the adjusting rod 2, and the coil assembly 3 attracts the ejector pin 5 when energized, so that the ejector pin 5 overcomes the elastic force of the elastic member 4 and moves away from the liquid outlet 51 and abuts against the adjusting rod 2. The coordination among the adjusting rod 2, the coil assembly 3, the elastic member 4 and the ejector pin 5 makes the overall structure very simple, which can not only be flexibly used in cold glue guns and hot glue guns, but also has strong versatility, and because of its simple and flexible structure, the activity of the ejector pin 5 is very flexible, and has the advantage of fast response.
