Description

Technical Field

[0001] The present invention relates to the technical field of glue gun equipment, and in particular to a simple two-component glue gun. Background Art

[0002] A glue gun is a tool for applying glue. To improve the drying effect of polyurethane foam sealant, the polyurethane foam sealant can be mixed with a drying aid (curing agent) for use.

[0003] Most of the glue guns on the market for extruding polyurethane foam sealant are industrial products, which are inconvenient to operate. Some of them also require power drive and are not suitable for simple household work. To better suit household work and reduce the professional requirements during the operation process, there are currently several dual-channel two-component glue guns introduced on the market. For example, in the Chinese invention patent with the patent number CN202321001272.4, a portable aerosol-type two-component raw material mixing and dispersing system is disclosed. In this solution, a mixing tube for mixing two components A and B is connected to the left end of the gun body. Component A flowing out of the aerosol-type component A pipeline and component B flowing out of the aerosol-type component B pipeline both enter the mixing tube for mixing, and after mixing, it is sprayed out. In actual application, since components A and B react in the mixing tube, during the first use of the mixing tube, glue can be continuously discharged. However, when it is used again, since some reactants will remain in the mixing tube and solidify, the mixing tube will be blocked, and at this time, glue cannot be discharged smoothly, and the mixing tube needs to be replaced, which is troublesome to operate. Moreover, if the connection between the mixing tube and the gun head is blocked, it will even cause difficulty in disassembling the mixing tube. In addition, since the mixing tube is a disposable item, the above glue gun needs to be equipped with multiple mixing tubes, resulting in high material costs and great waste. Summary of the Invention

[0004] To solve the above problems, the present invention proposes a simple two-component glue gun.

[0005] The technical solution adopted by the present invention is: a simple two-component glue gun, comprising:

[0016] Preferably, a glue flow pipeline for the foaming glue to flow is arranged in the rubber tube, and the glue flow pipeline extends forward and backward from the introduction hole.

[0017] Preferably, in the pressed state, the foaming glue ejected from the front end of the glue flow pipeline and the drying aid ejected from the front end of the output channel are mixed outside the glue gun.

[0018] More preferably, a step for cooperatively abutting against the wrench is arranged on the outer wall of the rubber tube.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. It is more convenient to install. Only need to install a foaming glue tank on the first installation port and a drying aid tank on the second installation port to complete the assembly.

[0021] 2. It is more convenient to use. After pressing the wrench, glue can be ejected. Since the foaming glue and the drying aid react outside the glue gun, the reaction products will not remain in the gun head, and the gun head will not be blocked. Therefore, the gun head at the front end of the drying aid tube does not need to be frequently replaced, and the use cost is low.

[0022] 3. Since the drying aid tube is sleeved on the outer part of the rubber tube at a position closer to the front, it is equivalent to a single-tube structure, and the structure is more compact and stable, and the assembly of the glue gun will be more convenient.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0039] Specific implementation scheme: Refer to Figures 1-10 This invention is a simple two-component glue gun, including:

[0040] A gun seat main body 100, on which a first feeding component 120 and a second feeding component 130 are installed. A first input pipeline 122 is provided in the first feeding component 120, and a second input pipeline 132 is provided in the second feeding component 130;

[0041] A rubber tube 200, installed on the gun seat main body 100 and passing through the first feeding component 120. The rubber tube 200 extends in the front-back direction, and an introduction hole 230 is provided on the rubber tube 200;

[0042] A drying agent tube 500, with its rear end installed on the second feeding component 130 and extending in the front-back direction. The drying agent tube 500 is sleeved on the outer part of the rubber tube 200 at a position closer to the front, and cooperates with the rubber tube 200 to jointly form a diversion channel 510. The second input pipeline 132 is communicated with the diversion channel 510. A gun rod head 520 is provided at the front end of the drying agent tube 500. The rubber tube 200 passes through the gun rod head 520. An output channel 530 is provided between the gun rod head 520 and the outer wall of the rubber tube 200. An opening and closing structure for adapting and adjusting whether the diversion channel 510 and the output channel 530 are communicated is provided between the gun rod head 520 and the rubber tube 200;

[0043] The wrench 300 is hingedly installed on the gun seat body 100 and has a released state and a pressed state. In the released state, the first input pipeline 122 and the inlet hole 230 are disconnected, and the opening and closing structure is closed; in the pressed state, the wrench 300 drives the hose 200 to translate backward relative to the drying agent pipe 500, the first input pipeline 122 and the inlet hole 230 are communicated, the opening and closing structure is opened, the foaming glue in the first input pipeline 122 enters the hose 200 through the inlet hole 230, and the drying agent in the diversion channel 510 enters the output channel 530;

[0044] The return spring 400 is arranged in the gun seat body 100 and abuts against the rear end of the hose 200.

[0045] As a preferred implementation manner of this embodiment, the opening and closing structure includes a wedge surface 240 arranged on the outer wall of the hose 200 and a guiding inclined surface 521 arranged at the rear end of the gun rod head 520. A closing point 522 is formed between the front end of the guiding inclined surface 521 and the rear end of the output channel 530.

[0046] Refer to Figure 4 、 Figure 7 and it can be seen that in the released state, the closing point 522 abuts against the wedge surface 240 and cuts off the diversion channel 510 and the output channel 530; refer to Figure 8 and Figure 10 and it can be seen that in the pressed state, the closing point 522 leaves the wedge surface 240, and the diversion channel 510 and the output channel 530 are communicated.

[0047] Working principle of the opening and closing structure: Refer to Figure 4 and Figure 7 and it can be seen that the extending direction of the guiding inclined surface 521 and the extending direction of the output channel 530 form an included angle with each other, and a closing point 522 is formed at the bent position. In the released state, the closing point 522 abuts against the wedge surface 240, thereby cutting off the diversion channel 510 and the output channel 530. Refer to Figure 8 and Figure 10 and when the hose 200 translates backward, the wedge surface 240 will also translate backward. Since the position of the gun rod head 520 remains unchanged, at this time, the closing point 522 leaves the wedge surface 240, the diversion channel 510 and the output channel 530 are communicated, and the drying agent in the diversion channel 510 will enter the output channel 530.

[0048] Then, please refer to Figures 1-4It can be seen that the upper end of the first feeding component 120 is provided with a first mounting port 121 for connecting to the foaming rubber tank, and the first feeding component 120 also includes a first sleeve joint 123 for the rubber hose 200 to pass through, and the first input pipeline 122 is arranged between the first mounting port 121 and the first sleeve joint 123. In the loosened state, the inner wall of the first sleeve joint 123 blocks the connection between the first input pipeline 122 and the introduction hole 230.

[0049] Next, in this embodiment, the upper end of the second feeding assembly 130 is provided with a second mounting port 131 for connecting to the drying agent tank. The second feeding assembly 130 also includes a second sleeve joint 133 for the hose 200 to pass through. The second sleeve joint 133 is arranged in front of the first sleeve joint 123. The second input pipeline 132 is arranged between the second mounting port 131 and the second sleeve joint 133. The rear end of the drying agent tube 500 extends into and is fixed inside the second sleeve joint 133.

[0050] In addition, in the present embodiment, the gun seat body 100 includes a rear base 110, a handle 140 is fixed on the rear base 110, a return spring 400 is arranged inside the rear base 110, and the gun seat body 100 also includes a first connecting member 150 arranged between the rear base 110 and the first feed assembly 120, and a second connecting member 160 arranged between the first feed assembly 120 and the second feed assembly 130.

[0051] Here, the gun holder body 100 is an integrally formed design, and the rear base 110, the first feed assembly 120, the second feed assembly 130, the handle 140, the first connecting member 150 and the second connecting member 160 do not need to be assembled separately, and the structure is more stable.

[0052] Then, see Figure 4 and 5 It can be seen that the wrench 300 is hingedly mounted on the first connecting member 150 , and a step 220 for cooperating with and abutting the wrench 300 is provided on the outer wall of the hose 200 .

[0053] In this embodiment, when the wrench 300 is manually bent backward, the wrench 300 rotates clockwise around the hinge point on the first connecting member 150 and squeezes the step 220 on the hose 200 backward, thereby driving the hose 200 to translate backward.

[0054] Next, see Figure 4 , Figure 6 , Figure 8 and Figure 9It can be seen that in this embodiment, the front end of the rear base 110, the first sleeve joint 123 and the front and rear ends, and the front end of the second sleeve joint 133 are all threadedly installed with plugs, and the hose 200 passes through all the plugs. In the loosened state, the inner wall of the plug located at the rear end of the first sleeve joint 123 blocks the connection between the first input pipeline 122 and the introduction hole 230.

[0055] In the above, the working principle of controlling the backward translation of the hose 200 by turning the wrench 300 has been described, as well as the working principle that during the backward translation of the hose 200, the opening and closing structure is opened, and the drying aid located in the guide channel 510 enters the output channel 530.

[0056] See also Figure 4 and Figure 5 It can be seen that in this embodiment, a rubber flow pipeline 210 for the flow of foamed rubber is provided in the rubber hose 200, and the rubber flow pipeline 210 extends forward and backward from the introduction hole 230.

[0057] The glue discharging principle of the rubber hose 200 is described below:

[0058] See also Figure 4 , Figure 6 It can be seen that in this embodiment, there are two introduction holes 230 and they are respectively arranged on the upper and lower sides of the hose 200. By setting plugs at both the front and rear ends of the first sleeve joint 123, the hose 200 passes through the plugs, so that there is a gap between the outer wall of the hose 200 and the channel inside the first sleeve joint 123, and the foam glue flowing out from the first input pipeline 122 will continue to fill the gap. When the wrench 300 is in a loose state, the introduction hole 230 will be sealed by the plug, and the foam glue in the gap cannot enter the hose 200. When the wrench 300 is in a pressed state, as described above, the hose 200 will move backwards, and at this time, the two introduction holes 230 are connected to the gap, and the foam glue in the gap will enter the rubber flow pipeline 210 in the hose 200.

[0059] More specifically, in the pressed state, the foaming glue sprayed from the front end of the self-flowing glue pipeline 210 and the drying aid sprayed from the front end of the output channel 530 are mixed outside the glue gun.

[0060] Note that, in this embodiment, the internal pressures of the foaming glue in the gap and the drying aid in the diversion channel 510 are both very high. When the wrench 300 is in the pressed state, the foaming glue in the gap will instantaneously impact and enter the glue flow pipeline 210, and the drying aid in the diversion channel will instantaneously impact and enter the output channel 530, and then will basically be ejected from the front of the gun head 520 regardless of the front or back. When the foaming glue and the drying aid are ejected forward simultaneously, the two will undergo a chemical reaction outside the glue gun, thereby accelerating the curing of the foaming glue.

[0061] The above are only the preferred embodiments of the simple two-component glue gun of the present invention, and do not limit the patent scope of the present invention. Any equivalent structural transformation made under the inventive concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields is included in the patent protection scope of the present invention.
