Description

Technical Field

[0001] This invention belongs to the field of glue gun technology, specifically relating to a low-pressure glue gun for mechanical rolling glue application. Background Technology

[0002] A glue gun is a tool for applying or extruding glue. A two-component glue tube is placed on the gun, and force is applied to the end of the tube to expel the two-component glue. The tube head connects to the gun nozzle, where the glue is forced into the nozzle, mixed evenly, and then expelled. The nozzle tip is placed at the desired application point, and the mixed glue is then applied. Glue guns are widely used in construction and decoration, electronics, automobiles and auto parts, shipbuilding and container industries. Glue guns are classified by the source of the application pressure: manual, pneumatic, and electric. Different pressure sources push the glue tube to extrude the glue. However, most glue guns currently use pressure for extrusion, with a stirring core installed inside the nozzle to promote even mixing of the two-component glue. This method involves higher resistance at the nozzle tip, requiring greater pressure and is more labor-intensive or electrically efficient. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a low-pressure glue gun for mechanical roller application, comprising, from back to front, a power unit, a glue tube bracket, and a head bracket connected in sequence. The glue tube bracket supports the glue tube, which includes two parallel branch tubes. Each branch tube has an opening at its head. The rear end of the glue tube abuts against the front end of the power unit. A flexible storage bag is detachably connected to the opening of each glue tube to receive the glue in the corresponding branch tube.

[0004] The head support includes, from back to front, a softening and extrusion section, a mixing section, and a nozzle. The softening and extrusion section supports and extrudes the storage bag, the mixing section supports and extrudes the flexible mixing bag, and the rear end of the mixing bag is detachably connected to the front outlet of the two storage bags for uniformly mixing the two-component colloid discharged from the storage bags into the mixing bag. The rear end of the nozzle is detachably connected to the front outlet of the mixing bag for applying the mixed colloid.

[0005] Traditional rubber hoses are either double-row or inner / outer sleeve type, with a single outlet at the front end to simultaneously discharge the two-component colloid into the nozzle. The two-component colloid mixes as it passes through the spiral stirring core inside the nozzle (resistance is relatively high) before being extruded from the nozzle. The entire process from hose to nozzle extrusion requires a single power unit, such as manual, pneumatic, or electric power. This invention redesigns the hose dispensing method. The hose uses a conventional double-row design, with each branch having its own outlet. Each branch can be a standard hose, reducing manufacturing complexity. Each branch outlet connects to a storage bag. Under the pressure of the softening extrusion unit, the storage bag softens the colloid inside, reducing resistance during subsequent mixing and promoting the mixing of the two-component colloid. The softening extrusion unit then simultaneously pushes the colloid from both storage bags into a mixing bag. The mixing unit squeezes the mixing bag, mixing the two-component colloid, and then pushes the mixed colloid into the nozzle for application. The softening and extrusion section and the mixing section of this invention provide power respectively, applying force to the storage bag and the mixing bag separately, which completely modifies the force application form of the glue gun, making the force application more concentrated, more targeted, and the mixing effect better.

[0006] Optionally, the softening extrusion section includes an upper extrusion section and a lower extrusion section. The upper extrusion section is located above the storage bag, and the lower extrusion section is located below the storage bag. The upper extrusion section includes two parallel upper tracks and an upper roller that moves along the upper tracks. The lower extrusion section includes two parallel lower tracks and a lower roller that moves along the lower tracks. The upper roller and the lower roller are rod-shaped.

[0007] Both the upper and lower tracks are horizontally set and parallel to the axial direction of the hose; the storage bag is located between the two upper tracks and also between the two lower tracks; the upper and lower rollers work together to squeeze the storage bag during movement.

[0009] Optionally, a support groove is provided above the rear end of the upper track. The support groove is connected to the upper track. When the storage bag is filled with glue, it needs to be loosened. After the upper roller moves to the rear end of the upper track, both ends of the upper roller can continue to move upward and enter the support groove, increasing the distance between the upper roller and the lower roller.

[0010] Further optionally, the side of the lower track facing the storage bag is the inner side, and the top of the inner side of each lower track is provided with a horizontal first groove rail. The first groove rail protrudes in a direction away from the storage bag, and the first groove rails of the two lower tracks have the same height.

The two sides of the first base plate can be inserted into the two first groove rails respectively, and can move along the first groove rails in the direction of approaching or moving away from the rubber tube, and the first base plate is located above the lower roller.

[0012] Optionally, the mixing section includes a side extrusion section, an upper rolling section, and a lower rolling section. The upper rolling section includes two upper supports and an upper roller mounted on the upper supports. The lower rolling section includes two lower supports and a lower roller mounted on the lower supports. The side extrusion section includes a side track and a side roller that moves along the side track.

[0013] The upper roller, lower roller, and side rail are all parallel to the axial direction of the hose and also parallel to the mixing bag; the upper roller is above the mixing bag, the lower roller is below the mixing bag, and the side rail is beside the mixing bag.

[0016] Further optionally, the side roller is perpendicular to the mixing bag and positioned above the mixing bag, for extruding the uniformly mixed colloid inside the mixing bag out of the mixing bag and into the nozzle;

[0017] The side track has a straight track perpendicular to the mixing bag at one end near the rear end of the mixing bag. This straight track points away from the mixing bag, so as to keep the side roller away from the mixing bag.

[0018] Further optionally, a vertical suspension plate is provided on each of the two sides below the mixing bag. The side of the suspension plate facing each other is the inner side. A horizontal second groove rail is provided on the inner side of the suspension plate. The second groove rail protrudes away from the mixing bag.

Detailed Implementation

[0026] This embodiment provides a low-pressure glue gun for mechanical roller application, such as... Figures 1-4 As shown, from back to front, it includes a power unit 1, a hose 4 bracket 2 and a head bracket connected in sequence. The hose 4 bracket 2 is used to support the hose 4. The hose 4 includes two parallel branch pipes 5. Each branch pipe 5 has a pipe opening at its head. The rear end of the hose 4 abuts against the front end of the power unit 1. Each hose 4 pipe opening is detachably connected to a flexible storage bag 6 for receiving the colloid in the corresponding branch pipe 5.

[0027] The head support includes, from back to front, a softening and extrusion section 3, a mixing section 7, and a nozzle 8. The softening and extrusion section 3 supports and extrudes the storage bag 6, and the mixing section 7 supports and extrudes the flexible mixing bag 9. The rear end of the mixing bag 9 is detachably connected to the front outlet of the two storage bags 6 for uniformly mixing the two-component colloid discharged from the storage bags 6 into the mixing bag 9. The rear end of the nozzle 8 is detachably connected to the front outlet of the mixing bag 9 for applying the mixed colloid.

[0028] Optionally, the softening extrusion section 3 includes an upper extrusion section and a lower extrusion section. The upper extrusion section is located above the storage bag 6, and the lower extrusion section is located below the storage bag 6. The upper extrusion section includes two parallel upper tracks 10 and an upper roller 12 that moves along the upper tracks 10. The lower extrusion section includes two parallel lower tracks 11 and a lower roller 13 that moves along the lower tracks 11. The upper roller 12 and the lower roller 13 are rod-shaped.

[0029] The upper track 10 and the lower track 11 are both set horizontally and parallel to the axial direction of the hose 4; the storage bag 6 is located between the two upper tracks 10 and the two lower tracks 11; the upper roller 12 and the lower roller 13 cooperate to squeeze the storage bag 6 during the movement.

[0030] Further optionally, the upper roller 12 is perpendicular to the upper track 10, and the two ends of the upper roller 12 are slidably connected to the two upper tracks 10; the lower roller 13 is perpendicular to the lower track 11, and the two ends of the lower roller 13 are slidably connected to the two lower tracks 11.

[0031] Further optional, a support groove 14 is provided above the rear end of the upper track 10. The support groove 14 is connected to the upper track 10. When the storage bag 6 is filled with glue, the storage bag 6 needs to be loosened. After the upper roller 12 moves to the rear end of the upper track 10, both ends of the upper roller 12 can continue to move upward and enter the support groove 14, increasing the distance between the upper roller 12 and the lower roller 13.

[0032] The support groove 14 is an annular shape with a notch at the bottom. The outer diameter of the upper roller 12 is interference-fitted with the notch, so that after the upper roller 12 enters the notch, it can be stuck in the support groove 14 and will not fall down.

[0033] Further optionally, the side of the lower track 11 facing the storage bag 6 is the inner side, and the top of the inner side of each lower track 11 is provided with a horizontal first groove track 15. The first groove track 15 protrudes in a direction away from the storage bag 6, and the first groove track 15 of the two lower tracks 11 has the same height.

[0034] The first groove rail 15 is provided with a detachable first base plate 17. The two sides of the first base plate 17 can be inserted into the two first groove rails 15 respectively, and move along the first groove rails 15 towards or away from the rubber tube 4. The first base plate 17 is located above the lower roller bar 13.

[0035] In use, the power unit 1 provides thrust to the rear end of the hose 4, simultaneously pushing the adhesive from the two branch tubes 5 into the corresponding storage bags 6. The power unit 1 then stops pushing. The front outlet of the storage bag 6 is closed. The upper roller 12 moves along the upper track 10, and the lower roller 13 moves along the lower track 11. The distance between the upper roller 12 and the lower roller 13 is adjusted by changing the height of the upper track 10 and the lower track 11. The rollers 12 and 13 can move synchronously and be vertically aligned, or they can be vertically misaligned, rolling back and forth above and below the storage bag 6 to soften the adhesive inside. When it is necessary to discharge the colloid, the upper roller 12 enters the support groove 14 and pushes the first bottom plate 17 into the first groove rail 15 to support the bottom surface of the storage bag 6. The upper roller 12 returns to the upper rail 10, opens the front outlet of the storage bag 6, and moves from the rear end of the upper rail 10 to the front end. Under the upper and lower squeezing action of the upper roller 12 and the first bottom plate 17, the colloid in the storage bag 6 is pushed out into the mixing bag 9. Then the front outlet of the storage bag 6 is closed to prepare for the next batch of colloid to enter and soften.

[0036] Since the storage bag 6 and the mixing bag 9 can operate independently without affecting each other, batch feeding and batch processing of the storage bag 6 and the mixing bag 9 are achieved. Finally, even if some adhesive remains inside the storage bag 6, since the two-component adhesive is not mixed inside the storage bag 6, the adhesive inside the storage bag 6 can remain in a closed state and can be used for the next application without curing, thus saving adhesive and solving the problem of residual adhesive in traditional glue guns curing and becoming unusable.

[0037] Optionally, the mixing section 7 includes a side extrusion section, an upper rolling section and a lower rolling section. The upper rolling section includes two upper supports 19 and an upper roller 21 mounted on the upper supports 19. The lower rolling section includes two lower supports 20 and a lower roller 22 mounted on the lower supports 20. The side extrusion section includes a side track 23 and a side roller 24 that moves along the side track 23.

[0038] The upper roller 21, lower roller 22, and side rail 23 are all parallel to the axial direction of the hose 4 and parallel to the mixing bag 9; the upper roller 21 is above the mixing bag 9, the lower roller 22 is below the mixing bag 9, and the side rail 23 is beside the mixing bag 9.

[0039] Further optionally, the two ends of the upper roller 21 are respectively connected to two upper brackets 19, and any end of the upper roller 21 is connected to the shaft of the first rotating motor 25, which can drive the upper roller 21 to rotate horizontally.

[0040] The two ends of the lower roller 22 are respectively connected to two lower supports 20, and any end of the lower roller 22 is connected to the shaft of the second rotating motor 26. The second rotating motor 26 can drive the lower roller 22 to rotate horizontally.

[0041] Further optionally, the upper support 19 is an inverted L-shape, including a lower first vertical slide 27 and an upper first horizontal slide 29. The top end of the first vertical slide 27 is connected to one end of the first horizontal slide 29, so that the upper roller 21 can slide continuously along the first vertical slide 27 and the first horizontal slide 29, thereby changing the position of the upper roller 21 and the first rotating motor 25.

[0042] A fixing plate 31 is provided at the bottom of the first vertical slide 27 near the first rotating motor 25. When the upper roller 21 is at the bottom of the first vertical slide 27, the fixing plate 31 is used to support the first rotating motor 25, so that the first rotating motor 25 drives the upper roller 21 to rotate.

[0043] Further optionally, the lower support 20 is L-shaped, including a lower second horizontal slide rail 30 and an upper second vertical slide rail 28. The bottom end of the second vertical slide rail 28 is connected to one end of the second horizontal slide rail 30, so that the lower roller 22 can slide continuously along the second vertical slide rail 28 and the second horizontal slide rail 30, thereby changing the position of the lower roller 22 and the second rotating motor 26.

[0044] A fixing hook 32 is provided at the top of the second vertical slide 28 near the second rotating motor 26. When the lower roller 22 is at the top of the second vertical slide 28, the fixing hook 32 is used to fix the second rotating motor 26, so that the second rotating motor 26 drives the lower roller 22 to rotate.

[0045] Further optionally, the side roller 24 is perpendicular to the mixing bag 9 and above the mixing bag 9, for extruding the uniformly mixed colloid inside the mixing bag 9 out of the mixing bag 9 and into the nozzle 8;

[0046] The side track 23 is provided with a straight track 33 perpendicular to the mixing bag 9 at one end near the rear end of the mixing bag 9. The straight track 33 points away from the mixing bag 9, so as to keep the side roller 24 away from the mixing bag 9.

[0047] Further optionally, a vertical suspension plate 34 is provided on each of the two sides below the mixing bag 9. The side of the suspension plate 34 facing each other is the inner side. A horizontal second groove rail 16 is provided on the inner side of the suspension plate 34. The second groove rail 16 protrudes away from the mixing bag 9. The second groove rail 16 of the two suspension plates 34 are at the same height.

[0048] The second groove rail 16 is provided with a detachable second base plate 18. The two sides of the second base plate 18 can be inserted into the two second groove rails 16 respectively, and move along the second groove rails 16 towards or away from the rubber tube 4. The second base plate 18 is located above the second horizontal slide 30.

[0049] Further optionally, a plurality of protruding bumps are evenly provided on the outer surfaces of the upper roller 21 and the lower roller 22, the length of the upper roller 21 and the lower roller 22 is equal to the length of the mixing bag 9, and the side roller 24 is rod-shaped and has a smooth surface.

[0050] In use, after the two-component colloid is filled into the mixing bag 9, the front and rear ends of the mixing bag 9 are sealed. The upper roller 21 moves along the upper support 19 to the bottom end of the first vertical slide 27, the first rotating motor 25 is placed on the fixed plate 31, and the lower roller 22 moves along the lower support 20 to the top end of the second vertical slide 28, and the second rotating motor 26 is fixed by the fixing hook 32. At this time, the distance between the upper roller 21 and the lower roller 22 is small, and both are pressing the surface of the mixing bag 9. During the horizontal rotation of the upper roller 21 and the lower roller 22 (rotation in the same direction or in opposite directions is acceptable), the two-component colloid in the mixing bag 9 is squeezed and pushed, so that it is mixed evenly. Then, the upper roller 21 moves along the upper support 19 to the end of the first horizontal slide 29 away from the mixing bag 9, and the lower roller 22 moves along the lower support 20 to the end of the second horizontal slide 30 away from the mixing bag 9. At this time, both the upper roller 21 and the lower roller 22 are away from the mixing bag 9.

[0051] The second base plate 18 is inserted into the second grooved rail 16 to support the bottom surface of the mixing bag 9. At this time, the side roller 24 is located at the end of the straight rail 33 away from the mixing bag 9. Then, the side roller 24 moves along the straight rail 33 to the rear end of the side rail 23. At this time, the side roller 24 is located at the rear end and above the mixing bag 9, with a small gap between the side roller 24 and the second base plate 18. As the side roller 24 moves along the side rail 23, it can squeeze the mixed adhesive inside the mixing bag 9 towards the gun head 8, ultimately achieving adhesive application through the gun head 8. The mixing bag 9 is detachable and can be discarded after use, replaced with a new mixing bag 9.

[0052] The nozzle 8 of this invention is the same as that of a traditional glue gun, except that no stirring core is provided inside the nozzle 8, and the length of the nozzle 8 is shortened to 2-5cm. Since the mixing part 7 has already completed the mixing of the two-component colloid, there is no need to rely on the stirring core for mixing in the longer nozzle 8. This invention solves the problem of high pushing resistance of traditional glue guns.

[0053] Optionally, a support frame is provided on the outer side of the softening extrusion section 3, the mixing section 7, and the nozzle 8. The rear end of the support frame is connected to the tube 4 bracket 2. In use, the operator can support the support frame by hand or other support objects, so that the head bracket can run smoothly.

[0054] Optionally, the power unit 1 and the hose 4 bracket 2 can be the same as those of a conventional glue gun, and can be manual, pneumatic, or electric. This allows a simple modification to an ordinary glue gun by installing the head bracket, making it ready for use.

[0055] Optionally, a pressure sensor is provided at the rear end of the outer side of the hose 4. The power unit 1 can push the component at the rear end of the hose 4 to contact the pressure sensor to detect the pushing pressure of the power unit 1. When the pressure is within a reasonable range, it means that there is still adhesive in the hose 4. When the pressure is too high or too low, it means that there is no adhesive in the hose 4 and the hose 4 needs to be replaced or inspected.
