Description

Technical Field

[0001] This invention belongs to the field of adhesive applicator technology, specifically a roller-type adhesive applicator. Background Technology

[0002] Glue applicators are commonly used tools in construction, primarily for holding and applying glue. Common types include sponge-type, brush-type, flat-head type, and roller-type. Sponge-type applicators have a sponge layer at the glue outlet on the cap, providing resistance and elasticity for even application. Flat-head type applicators have a flexible plastic flat head at the top of the cap with a small dispensing hole at the bottom. The glue flows through this hole onto the flat head, which is then used for application. To achieve even application of the adhesive, two types of adhesive bottles are used. One type uses a brush on the top of the bottle cap to apply the adhesive evenly. The other type has a roller on the bottle cap, where the adhesive flows onto the roller and is rolled to achieve even application. However, existing roller-type adhesive bottles often allow the adhesive to flow out naturally, making it impossible to control the flow rate. When the roller rolls quickly, the adhesive flow rate may be slower than the roller's application speed, resulting in interruptions in the application. This affects the speed and quality of the application. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a roller-type glue applicator.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a roller-type adhesive applicator, comprising a bottle body and a roller, a cap being provided on the bottle body, a roller being provided on the top of the cap, one side of the roller being a first frustum, the other side of the roller being an adhesive applicator, an intermediate shaft being provided between the roller and the cap for connection, a first support base being provided on the cap, a transmission mechanism being sleeved on the first support base, a second frustum being provided at one end of the transmission mechanism for cooperation with the first frustum, an adjusting bolt being provided on one side of the first support base for abutting against the second frustum, a first synchronous wheel being provided at the other end of the transmission mechanism, an intermediate cavity being provided in the cap, a second support base being provided in the intermediate cavity, an extrusion device being sleeved on the second support base, a second synchronous wheel being provided at one end of the extrusion device, a transmission belt being provided between the first and second synchronous wheels for synchronous transmission, a liquid outlet pipe being sleeved on the cap, the liquid outlet pipe being a flexible pipe in the intermediate cavity portion, multiple extrusion rollers being provided at the other end of the extrusion device, the extrusion rollers extruding onto the liquid outlet pipe, and a liquid outlet being provided at the top of the cap. In this invention, during application, a pressing roller is used to press the liquid out. The second and first truncated cones cooperate with each other. When the roller rotates during application, it transmits power to the second truncated cone, which in turn transmits power coaxially to the first synchronous pulley. The first and second synchronous pulleys are synchronously transmitted to the extrusion device via a transmission belt, causing the extrusion wheel to rotate and extrude the liquid through the flexible dispensing tube. When it is necessary to change the application speed, i.e., the speed at which the colloid is applied, the adjusting bolt on one side of the first support seat abuts against the second truncated cone is adjusted to change the engagement position of the second and first truncated cones, thereby adjusting the transmission ratio between them. This changes the rotation speed of the extrusion device and thus the dispensing speed of the colloid.

[0005] In the above technical solution, preferably, a bearing is provided between the roller and the intermediate shaft, and the roller is sleeved on the intermediate shaft. Roller support seats are provided on both sides of the cover, and the roller support seats are provided with guide grooves. The two ends of the intermediate shaft are sleeved in the guide grooves, and springs are provided between the two ends of the intermediate shaft and the bottom of the guide grooves. This structure avoids the roller rotating and transmitting power to the extrusion device when not in use, which would cause the glue bottle to dispense liquid and thus prevent the glue at the outlet from solidifying and blocking the outlet.

[0006] In the above technical solution, preferably, a piston is installed inside the bottle body, and a push-out block is installed on the piston. This structure ensures that during high-altitude construction, air is squeezed out by the extrusion device, thereby enabling the piston to push the colloid out of liquid.

[0007] In the above technical solution, preferably, a bottom cap is provided at the bottom of the bottle body, a sealing ring is provided between the bottom cap and the bottle body, and a vent hole is provided on the bottom cap. This structure ensures that the piston inside the bottle body is pushed upward.

[0008] In the above technical solution, preferably, the transmission mechanism is provided with a central shaft, and the second frustum is connected to the central shaft via a key. This structure ensures axial movement of the second frustum while preventing its rotation.

[0009] In the above technical solution, preferably, a buffer pad is provided at the top of the adjusting bolt. This structure avoids damage to the second truncated cone caused by friction between the rotating second truncated cone and the adjusting bolt when the adjusting bolt is pressed against it.

[0010] In the above technical solution, preferably, a baffle plate is provided around the liquid outlet pipe. This structure ensures that the liquid outlet pipe does not completely bend and detach from the liquid outlet when the extrusion wheel extrudes it.

[0011] In the above technical solution, preferably, the multiple extrusion wheels of the extrusion device are connected by a second transmission belt.

[0012] Compared with the prior art, the present invention has the following beneficial effects: During construction, the present invention presses the roller when dispensing liquid. The second truncated cone and the first truncated cone cooperate. When the roller rotates during construction, it transmits power to the second truncated cone, and then coaxially transmits power to the first synchronous pulley. The first synchronous pulley and the second synchronous pulley transmit power synchronously to the extrusion device through the transmission belt, so that the extrusion wheel rotates and extrudes the soft liquid dispensing tube to dispense liquid. When it is necessary to change the construction speed, i.e., the speed of applying the colloid, the adjustment bolt that abuts against the second truncated cone on one side of the first support seat is adjusted to change the cooperation position between the second truncated cone and the first truncated cone, thereby adjusting the transmission ratio between them, thereby changing the rotation speed of the extrusion device and thus changing the dispensing speed of the colloid.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See Figures 1 to 8 A roller-type adhesive applicator includes a bottle body 1 and a roller 3. A cap 2 is mounted on the bottle body 1, and the roller 3 is positioned on top of the cap 2. One side of the roller 3 is configured as a first frustum 31, and the other side is configured as an adhesive applicator 32. An intermediate shaft 5 connects the roller 3 and the cap 2. A first support base 23 is mounted on the cap 2, and a transmission mechanism 6 is sleeved on the first support base 23. One end of the transmission mechanism 6 has a second frustum 62 that engages with the first frustum 31. An adjusting bolt 7 is mounted on one side of the first support base 23, abutting against the second frustum 62. The other end of the transmission mechanism 6... The cover 2 is provided with a first synchronous wheel 61, the cover body 2 is provided with an intermediate cavity 27, the intermediate cavity 27 is provided with a second support seat 24, the extrusion device 8 is sleeved on the second support seat 24, one end of the extrusion device 8 is provided with a second synchronous wheel 81, a transmission belt 10 is provided between the first synchronous wheel 61 and the second synchronous wheel 81 to achieve synchronous transmission, the cover body 2 is provided with a liquid outlet pipe 13, the liquid outlet pipe 13 is set as a flexible pipe in the intermediate cavity 27 part, the other end of the extrusion device 8 is provided with multiple extrusion wheels 82, the extrusion wheels 82 extrude on the liquid outlet pipe 13, and the top of the cover body 2 is provided with a liquid outlet 21. In this invention, during application, the pressing roller 3, the second truncated cone 62 and the first truncated cone 31 cooperate. When the roller 3 rotates during application, it transmits power to the second truncated cone 62, and then coaxially to the first synchronous pulley 61. The first synchronous pulley 61 and the second synchronous pulley 81 are synchronously transmitted to the extrusion device 8 through the transmission belt 10, so that the extrusion wheel 82 rotates and extrudes the soft liquid outlet tube 13 to achieve liquid dispensing. When it is necessary to change the application speed, i.e., the speed of applying the colloid, the adjusting bolt 7 that abuts against the second truncated cone 62 on one side of the first support seat 23 is adjusted to change the cooperation position between the second truncated cone 62 and the first truncated cone 31, thereby adjusting the transmission ratio between them, thus changing the rotation speed of the extrusion device 8 and thus changing the dispensing speed of the colloid.

[0022] In this embodiment, a bearing 12 is provided between the roller 3 and the intermediate shaft 5, and is sleeved on the intermediate shaft 5. First support seats 23 are provided on both sides of the cover 2, and each first support seat 23 has a guide groove 26. Both ends of the intermediate shaft 5 are fitted into the guide groove 26, and springs 11 are provided between both ends of the intermediate shaft 5 and the bottom of the guide groove 26. This structure avoids the roller 3 rotating and transmitting power to the extrusion device 8 when not in use, preventing the adhesive from dispensing from the dispensing bottle and causing the adhesive at the dispensing port 21 to solidify and block the port 21.

[0023] In this embodiment, a piston 4 is installed inside the bottle body 1, and a push-out block 41 is installed on the piston 4. This structure ensures that during high-altitude construction, air is squeezed out by the squeezing device 8, thereby enabling the piston 4 to push the colloid out of liquid.

[0024] In this embodiment, a bottom cover 9 is provided at the bottom of the bottle body 1, a sealing ring 92 is provided between the bottom cover 9 and the bottle body 1, and a vent hole 91 is provided on the bottom cover 9. This structure ensures that the piston 4 inside the bottle body 1 is pushed upward.

[0025] In this embodiment, the transmission mechanism 6 is provided with a central shaft 63, and the second frustum 62 is connected to the central shaft 63 via a key 64. This structure ensures axial movement of the second frustum 62 while preventing rotation of the second frustum 62.

[0026] In this embodiment, a buffer pad 71 is provided at the top of the adjusting bolt 7. This structure avoids damage to the second frustum 62 caused by friction between the second frustum 62 and the adjusting bolt 7 when the adjusting bolt 7 is pressed against it.

[0027] In this embodiment, a baffle plate 25 is provided around the liquid outlet pipe 13. This structure ensures that when the extrusion roller 82 extrudes the liquid outlet pipe 13, the liquid outlet pipe 13 does not completely bend and detach from the liquid outlet 21.

[0028] In this embodiment, the multiple extrusion rollers 82 of the extrusion device 8 are connected by a second transmission belt 83.

[0029] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
