[0018] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention. The following describes various embodiments of the present invention in detail with reference to the accompanying drawings.

[0019] See also Figures 1 to 5 The utility model preferably provides a technical solution: an adjustable pneumatic glue nail machine, comprising a machine base 1, a machine body 2; a nailing device provided on the machine body 2 for nailing operation, which includes a slide rail and groove structure 22, and a double-rod cylinder 3 and a buffer 23 provided on the top of the machine body 2 and connected to the slide rail and groove structure 22; wherein, the nail gun head assembly provided on the double-rod cylinder 3 is used for the installation and nailing process of glue nail buckles; and a threaded joint 19 and a quick silencer exhaust throttle valve 21 provided at the air inlet of the double-rod cylinder 3, the quick silencer exhaust throttle valve 21 is provided at the air inlet end of the threaded joint 19 and It includes an integrated quick exhaust valve and exhaust throttle valve, and a built-in muffler-quick change connector, which are used to realize the speed regulation of the double-rod cylinder 3; it also includes a valve body assembly arranged on the fuselage 2, and the valve body assembly is used as a driving source for the double-rod cylinder 3 and the nail gun head assembly; further, the nail gun head assembly includes a gun head seat 4 arranged at the front of the double-rod cylinder 3, and a gun head pressure plate 5 and a presser foot 7 arranged at the front and bottom of the gun head seat 4; it also includes a gear gun head 6 arranged on the gun head pressure plate 5, wherein the gear gun head 6 is placed as a whole above the presser foot 7, and the gun head where it is located passes downward through the through hole where the presser foot 7 is located.

[0020] In this application, the gear gun head 6 includes a gun body, a gun head, a gun needle, and a gun head cylinder;

[0021] How this application works: Combined Figure 1 、 2 As shown in Figure 5, by driving the valve body assembly, the double-rod cylinder 3 and the buffer 23 provided on the fuselage 2 can drive the nail gun head assembly provided on the double-rod cylinder 3 to move longitudinally. In this process, the nail gun head assembly moves downward and the pressure foot 7 first contacts the product, which plays a simple fixing role. Then, after the double-rod cylinder 3 is in place, the gun head where the gear gun head 6 is located is inserted into the product, and the valve body assembly is operated again. The gun needle where the gear gun head 6 is located fires the consumable glue needle, so that the product is connected and fixed together by the glue needle. After completing the action, the valve body assembly is closed, and the gear gun head 6 moves upward, and the whole returns to the initial state. This reciprocating process realizes the continuous nailing process of the glue needle.

[0022] The design highlight of the present application is that the quick silencer exhaust throttle valve 21 installed at the intake end of the double-rod cylinder 3 is integrated with the quick exhaust valve and the exhaust throttle valve. This design enables the quick silencer exhaust throttle valve 21 to have a speed regulation function. At the same time, this function can adjust the speed according to personal needs. Specifically, it is achieved by adjusting the size of the air inlet of the quick silencer exhaust throttle valve 21. Manually turn it clockwise to reduce the speed, and manually turn it counterclockwise to increase the speed. After the adjustment, tighten the nut. The quick silencer exhaust throttle valve 21 installed at the inlet end of the double-rod cylinder 3 by the threaded joint 19 of the present application greatly improves the operating speed of the double-rod cylinder 3. The cylinder speed is about 30-60% faster than before.

[0023] Furthermore, the valve body assembly includes a downward pressure solenoid valve 17 and a nailing solenoid valve 18 which are installed on one side of the fuselage 2, and the downward pressure solenoid valve 17 and the nailing solenoid valve 18 are used to drive the double-rod cylinder 3 and the gear gun head 6 respectively; and an air pressure valve assembly is arranged on the outer wall of the fuselage 2 close to the downward pressure solenoid valve 17 and the nailing solenoid valve 18, wherein the air pressure valve assembly consists of an air pressure valve body 10, air source switches 11 at both ends of the air pressure valve body 10, a first threaded elbow joint 13, and a threaded straight-through joint 12 at the end of the air source switch 11.

[0024] Combine Figure 1 、 5 As shown, this machine has two solenoid valves, a downward pressure solenoid valve 17 and a nailing solenoid valve 18, both of which are model 4V110-06, and are used to control the double-rod cylinder 3 to move up and down and control the gear gun head 6 for nailing;

[0025] Here is the working principle of the downward pressure solenoid valve 17 and the nailing solenoid valve 18; the solenoid valve is usually composed of a coil, a valve core and a valve body. When the coil is energized, a magnetic field is generated to move the valve core, thereby changing the direction and pressure of the airflow. Specifically: the size of the opening is controlled by the solenoid valve coil, the flow rate of the airflow is adjusted, and the movement speed of the cylinder is changed; the extension and retraction of the cylinder are achieved by controlling the air intake and exhaust of the cylinder; the direction of the airflow is changed by changing the position of the valve, and the pneumatic valve body 10 is an existing mature technology and will not be described in detail.

[0026] Furthermore, a foot pedal plug 14 is provided on one side of the body 2 close to the air pressure valve assembly.

[0027] Combine Figure 1 As shown, the pedal plug 14 can be connected to the pedal. When the pedal is triggered once, the double-rod cylinder 3 and the gear gun head 6 move straight down to work. When the foot pedal is released, the double-rod cylinder 3 and the gear gun head 6 return to the original point, and the operation can be performed by analogy.

[0028] Furthermore, a safety cover 8 is provided on the front wall of the body 2 and placed below the nailing device; and a wear-resistant pad 9 is provided on the safety cover 8 for supporting the product.

[0029] Here, the safety cover 8 is used to receive the product, and the wear-resistant pad 9 can be used as the nailing operation point between the gun head needle of the gear gun head 6 and the product, and its characteristics increase the service life of the device.

[0030] Furthermore, a control panel 16 and a power plug 15 are provided on a side of the body 2 away from the air pressure valve assembly.

[0031] Here, the functional characteristics of the control panel 16 are as follows:

[0032] 1. With counting function; the machine counts 1 each time it is connected, and the counting can reach 99999 times. Press the counting function key for 3 seconds or more to return the value to zero and start counting again.

[0033] 2. Three gears are set; the corresponding gear is adapted according to the injection thickness, and the injection thickness range has been marked;

[0034] The design principle of the gear position is determined by the time of the time difference pause. The shorter the pause time, the thinner the product will be; the longer the pause time, the thicker the product will be.

[0035] The set value is as follows: The unit is: milliseconds ms

[0036] First stop: F1 ----1.50 F2----0.00

[0037] Second gear: F3-----1.60 F4--------0.00

[0038] 3rd gear F5-----1.80 F6----0.00

[0039] Example 1: The product thickness is 15-20mm, which should be suitable for use in the first gear. Due to the thin product, the double-rod cylinder 3 and the gun head where the gear gun head 6 is located go down at the same time. When the gun head where the gear gun head 6 is located touches the product, the gun head cylinder inside the gear gun head 6 works, and at the same time, the ejector where the gear gun head 6 is located pushes out the glue needle to buckle the product, and the double-rod cylinder 3 and the gun head cylinder are reset at the same time.

[0040] Note: When the double-rod cylinder 3 goes down with the gun head, the gun head cylinder has already started to operate in mid-air, and the operation time is 150 milliseconds.

[0041] Example 2: The product thickness is 35-40mm, which should be suitable for use in the third gear. The operating steps are as above.

[0042] Note: When the double-rod cylinder 3 goes down with the gun head, the gun head cylinder has already started to operate in mid-air, and the operation time is 180 milliseconds.

[0043] Explanation: Regardless of the gear position, the reset time is the same and unaffected. The main difference lies in the length of time the gun head cylinder operates. The control cylinder's pause time is F1, F3, and F5; the control reset cylinder's pause time is F2, F4, and F6, and their times are all the same, which is 0.

[0044] With nail driving (retracting) function; directly controlling the gun head to drive nails, it can quickly deal with gun head abnormalities, and can also control the gun head alone for effective adjustments.

[0045] Furthermore, the lower part of the double-rod cylinder 3 is provided with a second threaded elbow joint 20, which is combined with Figure 1 .

[0046] In the present invention, unless otherwise clearly specified and limited, terms such as "install", "connect", "connect", and "fix" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection. There are many ways of detachable installation, for example, it can be through plug-in and snap-fitting, or through bolt connection, etc.

[0047] The specific description of the present invention in the above embodiments is only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technical engineers in this field may make some non-essential improvements and adjustments to the present invention based on the contents of the above-mentioned utility model, which fall within the scope of protection of the present invention.
