Detailed Description
The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
As shown in fig. 1 and 2, a gun body structure of a fiber spray gun includes a gun body 10, a base 20 and a thimble 30. Wherein the gun body 10 and the base 20 are made of aluminum material, which has good heat dissipation for the whole structure.
A pinhole 11 penetrating through the upper end and the lower end of the gun body 10 is arranged in the gun body 10, a first counter bore 12 communicated with the pinhole 11 is formed in the upper end of the gun body 10, and a second counter bore 13 communicated with the pinhole 11 is formed in the lower end of the gun body 10;
the base 20 is connected to the lower end of the gun body 10, a boss 21 which is matched and connected with the second counter sink 13 is arranged in the center of the upper end of the base 20, the boss 21 is located in the second counter sink 13, a mounting groove 22 is arranged in the boss 21, a discharge hole 23 which penetrates through the base 20 is arranged in the center of the bottom of the mounting groove 22, a cushion block 24 is arranged in the mounting groove 22, an elastic body 25 which is abutted against the inner wall of the mounting groove 22 is sleeved on the cushion block 24, and a through hole 26 which is concentric with the discharge hole 23 is arranged in the;
the thimble 30 is slidably inserted into the pinhole 11, the lower end of the thimble 30 abuts against the through hole 26, and the upper end of the thimble 30 is provided with a thimble countersink 31 which is connected with the first countersink 12 in a matching manner.
The upper end of the gun body 10 is connected with a micro cylinder, the electromagnetic valve switches air pressure, the ejector pin 30 is driven by the air pressure to slide among the first counter bore 12, the needle hole 11 and the second counter bore 13, when the gun body needs to be closed, the ejector pin 30 is driven by the air pressure to slide downwards, the lower end of the ejector pin 30 abuts against the cushion block 24, impact force during abutting enables the position of the cushion block 24 to be finely adjusted in the mounting groove 22 through the elastic body 25 sleeved on the cushion block 24, so that the conical surface at the lower end of the ejector pin 30 is automatically and concentrically matched with the through hole 26 on the cushion block 24, and the through hole 26 is sealed and closed; when the hot melt adhesive is required to be opened, the air pressure drives the ejector pin 30 to slide upwards, the ejector pin 30 is separated from the cushion block 24, and the hot melt adhesive is discharged from the through hole 26 along the discharge hole 23.
As a further technical solution of this embodiment, a first seal ring installation groove 211 is formed on the outer peripheral side of the boss 21 for installing a seal ring on the boss 21 to enhance the sealing performance between the base 20 and the gun body 10.
As a further technical solution of this embodiment, the cushion block 24 is a cylinder, and since the outer peripheral surface of the cylinder is an arc surface, the range of movement when being abutted by the thimble 30 is large, which is convenient for the thimble 30 to concentrically cooperate with the through hole on the cushion block 24.
As a further technical scheme of the embodiment, the elastic body 25 is a rubber sealing ring, so that the structure is simple, the cost is low, and the cushion block 24 and the thimble 30 can be matched to achieve the fine adjustment effect.
As a further technical solution of this embodiment, a second seal ring installation groove 32 is disposed on the outer peripheral side of the thimble countersink 31 for installing a seal ring on the thimble countersink 31, so as to enhance the connection between the thimble countersink 31 and the inner wall of the first countersink 12, and when the pneumatic driving is performed, the thimble countersink 31 acts as a piston to allow the thimble to slide.
By adopting the technical scheme, the cushion block is arranged in the mounting groove of the boss, the cushion block is sleeved with the elastic body which is abutted to the inner wall of the mounting groove, when the thimble slides in the pinhole and the first counter sink through the electromagnetic valve and is abutted to the through hole on the cushion block, the elastic body slightly deforms, so that the conical surface of the lower end of the thimble automatically keeps concentric fit with the through hole on the cushion block, the closing effect and the sealing effect are effectively improved, and the problem of material leakage of the base is solved.
