DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. It is understood that, in the absence of conflict, some technical means of the various embodiments described herein can be replaced or combined with each other.

[0032] In the description of this utility model, the terms "first," "second," etc., if used, are used solely to distinguish the objects being described and do not convey any order or technical meaning. Therefore, an object defined as "first," "second," etc. may explicitly or implicitly include one or more of such objects. Furthermore, "a," "an," and similar terms do not imply a limitation on quantity, but rather indicate the presence of at least one, and "plurality" means at least two.

[0033] In the description of this utility model specification, reference to "one embodiment" or "some embodiments" means that one or more embodiments of the utility model include a particular feature, structure or characteristic described in conjunction with the embodiment. Therefore, the phrases "in one embodiment", "in some embodiments", "in other embodiments", "in other embodiments", etc. appearing in different places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments", unless otherwise specifically emphasized.

[0034] Reference Figure 13 In some embodiments, the hose adhesive 200 is similar to the tube structure of a common toothpaste tube, with a tube opening 201 and a tube tail 201 at each end. In applications, products such as 704 silicone often utilize this type of hose structure. For this type of hose adhesive, the present invention provides an electric glue extrusion gun for extruding the hose adhesive, thereby improving extrusion efficiency.

[0035] Reference Figure 1 and Figure 2 In some embodiments, the electric glue gun 100 includes a housing 10, a driving mechanism 20, a push rod 30, a tail clip 40, and an extrusion mechanism 50. The driving mechanism 20 is disposed inside the housing 10, and the push rod 30 is disposed on the housing 10 along a first direction X. The driving mechanism 20 and the push rod 30 are in transmission cooperation, and the driving mechanism 20 is used to drive the push rod 30 to move along the first direction X. Figure 7The push rod 30 is provided with a through slot 31 extending along the first direction X. The tail clip 40 is connected to the housing 10, and the tail clip 40 is located in the through slot 31. The tail clip 40 is provided with a clip slot 411 extending along the second direction Y. The extrusion mechanism 50 is provided at the front end of the push rod 30, and Figure 11 The extrusion mechanism 50 includes a first extrusion member 51 and a second extrusion member 52. A gap 53 is defined between the first extrusion member 51 and the second extrusion member 52. The gap 53 corresponds to the clamping groove 411. The first direction X corresponds to the length of the push rod 30, and the second direction Y is perpendicular to the first direction X. The push rod 30, tail clip 40, and extrusion mechanism 50 can be made of high-strength plastic or metal such as aluminum or aluminum alloy.

[0036] During application, the tail 202 of the hose rubber 200 is passed through the slit 53 and clamped and fixed in the clamping groove 411. The driving mechanism 20 can drive the push rod 30 to move, thereby driving the extrusion mechanism 50 to move along the first direction X away from the tail clamp 40, that is, the extrusion mechanism 50 moves from the tail 202 of the hose rubber 200 toward the pipe mouth 201, thereby using the extrusion mechanism 50 to extrude the hose rubber, which is easy to operate and precise to control.

[0037] Reference Figure 9 and Figure 10 In some embodiments, the tail clamp 40 includes a main body 41, an opening 42, and an adjusting member 43. The main body 41 is a U-shaped structure, and a clamping groove 411 is formed inside the main body 41. The opening 42 is provided on the opening side of the main body 41, and the opening 41 faces the extrusion mechanism 50. The adjusting member 43 is adjustably provided on the side of the main body 41, and the inner end of the adjusting member 43 extends into the clamping groove 411. In some embodiments, the adjusting member 43 can be a part such as a bolt. The adjusting member 43 is threadedly engaged with the side of the main body 41, and the central axis of the adjusting member 43 is perpendicular to the first direction X and the second direction Y. After the tube tail 202 of the hose rubber 200 is installed in the clamping groove 411, the tube tail 202 can be clamped and fixed by tightening the adjusting member 43 to prevent the hose rubber 200 from falling off during the rubber squeezing operation.

[0038] Reference Figure 11 and Figure 12In some embodiments, the first extrusion member 51 includes a first substrate 511 and a first extrusion portion 512. The first substrate 511 is generally U-shaped, with a slot 513 defined in the middle. The back surface of the first substrate 511 is connected to the front end of the push rod 30. The first extrusion portion 512 is located on the left half of the front side of the first substrate 511, and a mounting slot 514 is defined on the right half of the front side of the first substrate 511. The second extrusion member 52 includes a second substrate 521 and a second extrusion portion 522. The second substrate 521 is positioned within the mounting slot 514. The second extrusion portion 522 is located on the front side of the second substrate 521, and the second extrusion portion 522 is disposed opposite the first extrusion portion 512. The gap 53 is formed between the first extrusion portion 512 and the second extrusion portion 522, corresponding to the slot 513. The width of the gap 53 is smaller than the width of the slot 513. In some embodiments, the first extrusion portion 512 and the second extrusion portion 522 can be considered as a quarter-cylinder structure, with the opposing sides of the first extrusion portion 512 and the second extrusion portion 522 both being curved surfaces that arch toward the clamping groove 53. When securing the flexible rubber hose 200, the tube tail 202 can be sequentially passed through the clamping slit 53 and the slot 513 before being inserted into the clamping groove 411. During the glue extrusion operation, the push rod 30 drives the extrusion mechanism 50 from the tube tail 202 of the flexible rubber hose 200 toward the nozzle 201. The first extrusion portion 512 and the second extrusion portion 522 can push the glue in the flexible rubber hose 200 toward the nozzle 201, thereby achieving a better glue extrusion effect.

[0039] Furthermore, the extrusion mechanism 50 includes a hinge shaft 54 and a positioning ring 55. The bottom of the first substrate 511 and the bottom of the second substrate 521 are hingedly connected via the hinge shaft 54. A first positioning block 515 is provided at the top of the first substrate 511, and a second positioning block 523 is provided at the top of the second substrate 521. The positioning ring 55 is sleeved over the first positioning block 515 and the second positioning block 523. The positioning ring 55 can be an elastic rubber ring, for example. When clamping the hose glue 200, the positioning ring 55 can be removed first to leave a larger gap between the first extrusion part 512 and the second extrusion part 522 to facilitate the passage of the tube tail 202. After the tube tail 202 is clamped and fixed in the clamping groove 411, the positioning ring 55 is put on the first positioning block 515 and the second positioning block 523 to squeeze the tube body of the hose glue 200. The stretching degree of the positioning ring 55 can be adaptively adjusted according to the wall thickness of the hose glue 200, that is, the width of the gap 53 can be adjusted, thereby improving the adaptability of the electric glue gun 100 to hose glue 200 with different wall thicknesses.

[0040] Reference Figure 8In some embodiments, a first limiting protrusion 32 and a second limiting protrusion 33 are respectively provided on the bottom of both sides of the push rod 30. The first limiting protrusion 32 and the second limiting protrusion 33 are spaced apart in the first direction X, and the first limiting protrusion 32 is close to the front end of the through slot 31, and the second limiting protrusion 33 is close to the rear end of the through slot 31. Figure 4 A first travel switch 221 and a second travel switch 222 are provided in the housing 10 (on the driving mechanism 20 ). The first travel switch 221 corresponds to the first limit protrusion 32 , and the second travel switch 222 corresponds to the second limit protrusion 33 .

[0041] Among them, the specific structures of the first limit protrusion 32 and the second limit protrusion 33 can be reasonably set according to actual conditions. For example, in one embodiment, the first limit protrusion 32 and the second limit protrusion 33 are respectively set to a trapezoidal structure. In application, the first limit switch 221 and the second limit switch 222 can respectively adopt limit switch products in the prior art. For example, in one embodiment, the first limit switch 221 and the second limit switch 222 both include a connecting lever and a touch roller provided at the top of the connecting lever, and the top of the connecting lever of the first limit switch 221 is tilted toward the tail end of the push rod 30, and the top of the connecting lever of the second limit switch 222 is tilted toward the front end of the push rod. In this way, the movement range of the push rod 30 along the first direction X can be controlled to ensure the reliability of the electric glue extrusion gun 100. Specifically, during the movement of the push rod 30, when the first limit switch 221 touches the first limit protrusion 32, the first limit switch 221 is triggered, indicating that the push rod 30 has retreated to the first limit position; when the second limit switch 222 touches the second limit protrusion 33, the second limit switch 222 is triggered, indicating that the push rod 30 has advanced to the second limit position. The range between the first limit position and the second limit position is the movable range of the push rod 30.

[0042] Reference Figures 2 to 5 In some embodiments, the drive mechanism 20 includes a motor 21, a reduction gear housing 22, a first reduction gear assembly 23, and a second reduction gear assembly 24. The first reduction gear assembly 23 and the second reduction gear assembly 24 are respectively disposed in the reduction gear housing 22. The motor 21 engages with the first reduction gear assembly 23, which in turn engages with the second reduction gear assembly 24. The second reduction gear assembly 24 engages with the push rod 30. When the motor 21 is operating, power is transmitted to the push rod 30 via the first reduction gear assembly 23 and the second reduction gear assembly 24, causing the push rod 30 to move along the first direction X.

[0043] The reduction gearbox housing 22 may include a lower housing 22a and an upper housing 22b, which are detachably connected using screws and other components. Furthermore, limit blocks 223 are provided on either side of the upper portion of the upper housing 22a, with the centerline of the two limit blocks 223 perpendicular to the first direction X. The two limit blocks 223 limit the position of the push rod 30. The aforementioned first and second limit switches 221, 222 may also be provided at corresponding positions on either side of the upper housing 22a.

[0044] Preferably, the first reduction transmission assembly 23 can utilize a multi-stage planetary reducer. For example, in some embodiments, the first reduction transmission assembly 23 can utilize a three-stage planetary reducer or a four-stage planetary reducer. These reducers offer advantages such as high transmission ratio, high efficiency, compact structure, long life, small size, light weight, smooth operation, low noise, safe performance, and high precision, thereby ensuring the reliability and stability of the electric glue extrusion gun. Multi-stage planetary reducers are commonly used in this field and will not be further described here.

[0045] Reference Figures 3 to 5 In some embodiments, the second reduction transmission assembly 24 includes an inner ring gear 242, a planet carrier 243, multiple planetary gears 244, a driving gear 245, and a driven gear 246. The planet carrier 243 is drivingly connected to the first reduction transmission assembly 23. The multiple planetary gears 244 are respectively mounted on the planet carrier 243 and mesh with the inner ring gear 242. The driving gear 245 is disposed on the exterior of the reduction gearbox housing 22 (on the upper housing 22b) and is coaxially connected to the planet carrier 243. The driven gear 246 is disposed on the exterior of the reduction gearbox housing 22 (on the upper housing 22b) and meshes with the driving gear 245. Teeth 34 extending in the first direction X are provided on both sides of the push rod 30. The driving gear 245 and the driven gear 246 respectively mesh with the teeth 34 on either side. Furthermore, a washer 241 is disposed below the inner ring gear 242.

[0046] At the same time, most of the current electric glue extruding guns are push-button switches. Since the push rod 30 has inertia in its movement, even if the power is turned off by the switch, it is impossible to ensure the precise control of pausing the glue extrusion operation, which affects the reliability and glue extrusion quality of the electric glue extruding gun. Therefore, in the preferred embodiment of the present invention, the drive mechanism 20 also includes a stop assembly 25, referring to Figures 3 to 5The stop assembly 25 includes a stop switch 251, a stop member 252, a sleeve 253, and a spring 254. The stop switch 251 is mounted on the housing 10. The middle portion of the stop member 252 is hinged to the reduction gear housing 22. The upper end of the stop member 252 extends upward and bends toward the inner ring gear 242 to form a first bent portion 2521. The outer periphery of the inner ring gear 242 is provided with a plurality of slots 2421. The first bent portion 2521 is configured to engage with the slots 2421 of the inner ring gear 242. The lower end of the stop member 252 extends downward and bends toward the stop switch 251 to form a second bent portion 2522. The second bent portion 2522 extends into the inner cavity of the stop switch 251. The first bent portion 2521 and the second bent portion 2522 bend in opposite directions. The sleeve 253 is mounted on the reduction gear housing 22. A boss 2523 is also provided at the lower end of the stopper 252. The boss 2523 protrudes in the opposite direction from the second bent portion 2522. The boss 2523 is inserted into the sleeve 253, and the spring 254 is sleeved on the boss 2523. The stopper 252 is hingedly connected to the lower housing 22b, which has an opening corresponding to the stopper. The sleeve 253 is fixed to the lower housing 22b. Multiple slots 2421 are evenly spaced along the outer periphery of the inner gear ring 242. The number and depth of the slots 2421 can be adjusted based on actual conditions.

[0047] During operation, when the first bent portion 2521 engages the slot 2421 of the inner gear ring 242, the inner gear ring 242 is fixed, and the second reduction transmission assembly 24 has one degree of freedom. The driving force of the motor 21 is transmitted to the push rod 30 through the first reduction transmission assembly 23 and the second reduction transmission assembly 24, causing the push rod 30 to move in the first direction X, thereby achieving automatic glue extrusion. When the stop switch 251 is pressed, the spring 254 is compressed, and the stop member 252 rotates about its own hinge axis, causing the first bent portion 2521 to disengage from the slot 2421. The inner gear ring 242 is no longer fixed, and the second reduction transmission assembly 24 has two degrees of freedom. At this time, the push rod 30 encounters resistance, causing it to immediately stop moving, thereby pausing glue extrusion. After the stop switch 251 is no longer pressed, the spring 254 rebounds, driving the stop member 252 to rotate in the opposite direction about its own hinge axis, causing the first bent portion 2521 to reengage the slot 2421, and glue extrusion can resume. In this way, the stop assembly 25 is used to precisely control the suspension of glue extrusion, thereby improving the control accuracy and reliability of the electric glue extrusion gun.

[0048] The electric glue squeezing gun of the utility model is suitable for the glue squeezing operation of hose glue. During application, the tail of the hose glue passes through the clamping gap of the squeezing mechanism and is clamped in the clamping groove of the tail clamp. The driving mechanism can drive the push rod to move, thereby driving the squeezing mechanism to move in a direction away from the tail clamp, so that the hose glue is squeezed out by the squeezing mechanism, which is easy to operate; a limit bump is provided on the push rod, and a travel switch is correspondingly provided in the shell, which is convenient for limiting the moving range of the push rod; a stop assembly is also provided in the driving mechanism, which is convenient for realizing precise control of pausing glue squeezing, thereby improving the reliability and glue injection quality of the electric glue squeezing gun.

[0049] The present invention has been described with reference to the above embodiments. However, these embodiments are merely exemplary embodiments of the present invention. It should be noted that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and improvements made without departing from the spirit and scope of the present invention are within the scope of patent protection of the present invention.
