Description

Technical Field

[0001] The invention relates to the technical field of felt laminating auxiliary tools, in particular to a portable felt seam pressing and bonding device. Background Art

[0002] Felt cloth has a protective function and is widely used in the automotive field. Pasting felt cloth in the car can not only improve the aesthetics of the interior of the car, but also improve the overall sound insulation effect of the car. Some users will choose to paste felt cloth in some places in the car by glue, such as pasting felt cloth on the metal door frame of the car door.

[0003] In the utility model with authorization announcement number CN216009164U, a car felt covering device is disclosed. The car felt covering device is convenient for quick disassembly and assembly of the roller by providing a disassembly and assembly component on the outer surface of the angle adjustment component, so that rollers of different sizes can be replaced and suitable for different covering environments, thereby improving the scope of use and convenience and facilitating adjustment.

[0004] It can be seen that the above-mentioned felt cloth covering device mainly realizes the replacement of rollers of different sizes and improves convenience. However, there are still some shortcomings in specific use. When pasting felt cloth in the car, glue is generally sprayed on the part to be pasted first, and then the entire piece of felt cloth is gradually pasted on the part to be pasted in the car from one edge of the felt cloth, and the excess felt cloth on the edge of the felt cloth will be cut off by the staff with the help of a knife. In the process of pasting and leveling a whole piece of felt cloth, since the pasting starts from one edge of the felt cloth first, in the process of the subsequent operator cutting the excess felt cloth and smoothing the felt cloth to make it bonded to the flat part or other parts of the car frame, as time goes by, the glue at the other edge of the felt cloth will easily dry if it is not bonded to the edge of the felt cloth in time, resulting in the edge of the felt cloth being unable to fully bond to the part to be pasted, which will cause the edge seam of the edge felt cloth to warp. If the edge seam is not repaired and pressed in time, the felt cloth will not be well bonded. The above-mentioned equipment can only press the edge seam of the felt cloth, and cannot repair and press the edge seam.

DETAILED DESCRIPTION

[0018] The present invention will be further described below in conjunction with the embodiments.

[0019] like Figures 1 to 4 as well as Fig. 9As shown, a portable felt seam pressing and bonding device comprises a handheld plate 1, the handheld plate 1 is fixedly connected to an upper fixed plate 11, a side of the handheld plate 1 away from the upper fixed plate 11 is fixedly connected to a lower fixed plate 12, a side seam repair glue pressing mechanism is arranged on the upper fixed plate 11, the side seam repair glue pressing mechanism comprises a through groove 21 provided on the upper fixed plate 11, a groove block 22 is slidably connected inside the through groove 21, a spring 221 is connected between the groove block 22 and the groove surface of the through groove 21, a fixed support 23 is fixedly connected to the side of the groove block 22 away from the lower fixed plate 12, and the fixed support 23 is fixedly connected to the side of the groove block 22 away from the lower fixed plate 12. 3 is fixedly connected with a glue storage cylinder 24, and fluid glue for pasting felt cloth is stored in the glue storage cylinder 24. A cylinder cover 241 is detachably connected to the side of the glue storage cylinder 24 close to the handheld board 1. A piston 25 with a rod is inserted in the glue storage cylinder 24. The piston 25 with a rod and the glue storage cylinder 24 form a piston cylinder structure. A piston disk is provided on the part of the piston 25 with a rod located in the glue storage cylinder 24, and the piston 25 with a rod is movably connected to the cylinder cover 241. Specifically, the glue storage cylinder 24 and the cylinder cover 241 are made of transparent material, and the cylinder cover 241 is threadedly connected to the glue storage cylinder 24. The side of the glue storage cylinder 24 away from the lower fixed plate 12 is fixedly connected with an electric control telescopic rod 251. The end of the electric control telescopic rod 251 close to the handheld plate 1 is the output shaft end, and the output shaft end is fixedly connected to the end of the rod piston 25 close to the handheld plate 1. The side of the glue storage cylinder 24 away from the handheld plate 1 is connected with a glue outlet pipe 26. The glue outlet pipe 26 is a polyurethane hose that can be manually bent and maintained at the angle after bending. A valve is installed at the part where the glue outlet pipe 26 is connected to the glue storage cylinder 24. When in use, the valve is opened to connect the inside of the glue storage cylinder 24 with the glue outlet pipe 26. The end of the glue outlet pipe 26 away from the glue storage cylinder 24 is connected with an extension pipe 27. The extension pipe 27 is movably inserted with an adjustment pipe 28 in order to adjust the length of the adjustment pipe 28 extending out of the extension pipe 27, so as to facilitate the adjustment pipe 28 to be extended between the felt cloth and the vehicle frame for glue repair. When it is necessary to add glue to the glue storage cylinder 24, first rotate the cylinder cover 241 to separate it from the glue storage cylinder 24, and move the cylinder cover 241 along the rod piston 25 to the side away from the glue storage cylinder 24, and then use the electrically controlled telescopic rod 251 to extend the piston disk of the rod piston 25 to be pulled out of the glue storage cylinder 24, and then glue can be added to the glue storage cylinder 24.

[0020] like Figures 1 to 4 as well as Figure 8 and Fig. 9 As shown, a support shaft 211 is rotatably connected between the upper fixed plate 11 and the lower fixed plate 12 on the side away from the hand-held plate 1, a positioning plate 1 212 is fixedly connected to the end of the support shaft 211 close to the upper fixed plate 11, a positioning plate 213 is fixedly connected to the end of the support shaft 211 close to the lower fixed plate 12, and a flattening roller 214 is rotatably connected between the positioning plate 1 212 and the positioning plate 2 213 on the side away from the hand-held plate 1, and the outer surface of the flattening roller 214 is provided with an elastic silicone layer, and the outer surface of the elastic silicone layer is provided with anti-slip texture.

[0021] When the edge gap of the felt cloth needs to be pressed, the device can be used to add glue to the edge gap so that the edge gap of the felt cloth can be fully adhered to the surface of the car frame. Figure 2 When the user needs to add glue to the side seam of the felt cloth above, the user holds the handheld board 1 by hand, so that the lower end of the adjusting tube 28 is aligned with the side seam of the felt cloth and inserted into the side seam. Then the user starts the electric control telescopic rod 251 through the external controller and opens the valve at the connecting part of the glue outlet pipe 26 and the glue storage cylinder 24, driving the rod piston 25 to move horizontally in the direction close to the glue outlet pipe 26, thereby causing the glue inside the glue storage cylinder 24 to be squeezed out from the glue outlet pipe 26, and sent to the extension pipe 27 and the adjusting tube 28 through the glue outlet pipe 26, and finally discharged outward through the adjusting tube 28, and the discharged glue falls into the side seam between the felt cloth and the car frame. In this way, the user can hold the device and gradually perform glue filling treatment on other side seams of the felt cloth along the trajectory of the side seam. In this process, the user can control the output shaft end of the electric control telescopic rod 251 through the controller to drive the rod piston 25 to move slowly in the glue storage cylinder 24 to ensure that the glue in the glue storage cylinder 24 can be effectively squeezed out.

[0022] Through the cooperation of the electrically-controlled telescopic rod 251 and the glue storage cylinder 24, the edge seam between the felt cloth and the vehicle frame can be repaired with glue to avoid the glue at the edge drying out or uneven first application of glue, which may lead to poor bonding of the felt cloth. The user can replenish glue to ensure that there is enough glue at the edge seam of the felt cloth to bond with the vehicle frame, thereby ensuring the bonding effect of the felt cloth.

[0023] At the same time, when the user is repairing the glue along the felt cloth edge seam moving device, the flattening roller 214 will also be driven to move synchronously. When the adjustment tube 28 extends into the felt cloth edge seam, the outer surface of the flattening roller 214 also fits with the outer surface of the felt cloth. At this time, the operator can hold the support shaft 211 and the second positioning plate 213 by hand to ensure that the flattening roller 214 and the outer surface of the felt cloth remain in contact, and the adjustment tube 28 is located on the travel path of the flattening roller 214, so that when the adjustment tube 28 repairs the glue at the edge seam of the felt cloth, as the device moves, the flattening roller 214 can press the edge seam of the felt cloth coated with glue, so as to promote the felt cloth edge seam to fully contact with the surface of the frame through the glue, so as to achieve faster bonding. Therefore, when the glue is repaired at the felt cloth edge seam, the edge seam can be pressed at the same time to ensure that the edges of the felt cloth are fully bonded when the felt cloth is bonded, and to prevent the edge seam from warping after the felt cloth is pasted. When the user has completed the glue repair and the side seam pressing, the user can close the electric control telescopic rod 251 through the controller.

[0024] Furthermore, if Figure 1 and Figure 2 as well as Figures 5 to 7As shown, the outer wall of the adjusting tube 28 away from the end of the extension tube 27 is symmetrically fixedly connected with two limit strips 281, and the outer wall of the extension tube 27 is provided with a limit groove 282 at a position corresponding to the limit strip 281. The end of the limit strip 281 close to the glue outlet tube 26 is slidably matched with the adjacent limit groove 282, and the end of the adjusting tube 28 away from the glue outlet tube 26 is rotatably connected with a ring 29, and a cotton ring 210 is sleeved on the ring 29. After use, the cotton ring 210 can be manually removed for replacement.

[0025] When one end of the adjusting tube 28 away from the glue outlet tube 26 extends into the inner side of the edge seam of the felt cloth, the outer surface of the cotton ring 210 will fit with the surface of the vehicle frame. When the user holds the device to repair the glue along the edge seam, the ring 29 and the cotton ring 210 will rotate under the friction between the cotton ring 210 and the surface of the vehicle frame or the surface of the felt cloth, so that the cotton ring 210 can absorb the excess glue leaking from the adjusting tube 28.

[0026] In addition, when the user needs to add glue to the vertical edge seam of the felt cloth, the user can hold the device and rotate it 90 degrees. Figure 3 , so that the adjustment tube 28 is above the flattening roller 214, at this time, starting from the bottom of the felt cloth side seam, the side seam is repaired from bottom to top. Then the side seam is pressed from bottom to top by the flattening roller 214. When the side seam below the felt cloth needs to be repaired and pressed, the side seam is pressed from bottom to top. Figure 2 and Figure 3 , the user needs to rotate the entire device another ninety degrees so that the flattening roller 214 is above the adjusting tube 28, and then the user manually twists the glue outlet hose 26 so that the end of the adjusting tube 28 that discharges glue is aligned with the edge seam of the felt cloth, and the adjusting tube 28 is extended into the edge seam of the felt cloth, and the glue repair and pressing process can be carried out.

[0027] like Figures 8 to 11As shown, the portable felt seam pressing and bonding device also includes a manual switching function mechanism, which includes a convex plate 31, a positioning plate 213 symmetrically fixedly connected with two convex plates 31, a positioning plate 1 212 fixedly connected with an extension plate 3101 at one end away from the flattening roller 214, a fixed shaft 37 fixedly connected between the convex plate 31 and the extension plate 3101 on the side away from the flattening roller 214, and the outer surface of the fixed shaft 37 is symmetrically connected with two movable pressing plates 38, and the angle between the two movable pressing plates 38 is an acute angle, and the ends of the two movable pressing plates 38 that are attached to each other are rounded. The outer surfaces of the two movable pressing plates 38 are jointly attached with a rubber layer 39, the rubber layer 39 is elastic, and the outer surface of the rubber layer 39 is a smooth surface. A plurality of arc springs 310 are evenly fixedly connected between the two movable pressure plates 38. A mounting groove 32 is provided on the side of the lower fixed plate 12 away from the second positioning plate 213. A dial plate 33 is slidably connected in the mounting groove 32. Circular grooves are provided on both sides of the dial plate 33 to facilitate the finger contact of the user. The dial plate 33 can only slide horizontally inside the mounting groove 32. A concave plate 36 is fixedly connected to the top of the dial plate 33, and both convex plates 31 can be engaged with the concave plate 36. A side of the dial plate 33 away from the support shaft 211 is fixedly connected to a push rod 34, a spring 2 331 is connected between the dial plate 33 and the mounting slot 32, a control switch 35 is fixedly installed on the side of the mounting slot 32 away from the support shaft 211, and the control switch 35 is located on the moving path of the push rod 34, an electromagnet 1 311 is fixedly installed at the bottom of the fixed support 23 close to the handheld plate 1, and an electromagnet 2 312 is fixedly installed on the upper fixed plate 11, the position of the electromagnet 2 312 corresponds to the position of the electromagnet 1 311, and the magnetism of the two sides close to each other after power is turned on is opposite, a rack 313 is fixedly connected to one side of the bottom of the slot block 22, and a gear 314 is fixedly connected to the position of the support shaft 211 corresponding to the rack 313, and the gear 314 and the rack 313 are meshed with each other. The above-mentioned control switch 35, electromagnet 1 311, electromagnet 2 312 and the electric control telescopic rod are all connected to an external mobile power supply, and are powered by the mobile power supply.

[0028] When in use: when the user needs to press the felt cloth inside the car, the user uses his finger to move the dial plate 33, causing the dial plate 33 and the concave plate 36 to move horizontally toward the control switch 35, and the second spring 331 is compressed during the process. After the concave plate 36 moves, it will no longer be engaged with the convex plate 31 near the side of the movable pressing plate 38, so it will not block the second positioning plate 213 from rotating around the support shaft 211. When the push rod 34 moves to contact the control switch 35 and the control switch 35 is pressed, the electromagnet 1 311 and the electromagnet 2 312 are energized, and the opposite magnetic attraction between the two forces causes the electromagnet 1 311 to drive the fixed support 23, the slot block 22, the rack 313 and the rubber storage cylinder 24 to move horizontally toward the electromagnet 2 312. During the process, the spring 1 221 is compressed, and the movement of the rack 313 drives the gear 314 to rotate. When the electromagnet 1 311 and the electromagnet 2 312 are finally attached to each other, the gear 314 can be driven to rotate 180 degrees. The rotation of the gear 314 drives the support shaft 211 and the positioning plate 1 212 and the positioning plate 2 213 to rotate synchronously, so that the flattening roller 214 and the movable pressing plate 38 are rotated and exchanged. Then the user releases the pressure on the shift plate 33 with his finger, so that under the action of the rebound force of the second spring 331, the push rod 34 moves away from the control switch 35. At this time, the electromagnet 1 311 and the electromagnet 2 312 are still in the energized adsorption state. Under the action of the rebound force of the second spring 331, the concave plate 36 moves horizontally toward the direction close to the support shaft 211, so as to engage with the convex plate 31 close to the flattening roller 214, so as to fix the position of the support shaft 211, the flattening roller 214 and the movable pressing plate 38 after rotation adjustment, so that they remain in a fixed position. Then the user can use the movable pressing plate 38 to press the felt cloth on some angle parts of the car frame with the handheld device. When the user needs to switch the flattening roller 214 and the movable pressure plate 38 to the initial state, the user needs to use his finger to push the dial plate 33 again to move horizontally in the direction close to the control switch 35, so that the push rod 34 moves to contact the control switch 35 and presses the control switch 35 again. At this time, the electromagnet 1 311 and the electromagnet 2 312 are powered off. The control switch 35 is a known technology in the prior art, and its working principle is no longer repeated here. Therefore, under the action of the rebound force of the spring 1 221, the rack 313 is driven to move and reset, and then the rack 313 drives the gear 314 to rotate in the opposite direction and reset, thereby resetting the flattening roller 214 and the movable pressure plate 38 to the initial state. Then the user releases the pressure on the dial plate 33 again, so that the concave plate 36 is engaged with the convex plate 31 close to the side of the movable pressure plate 38, thereby ensuring the stability of the flattening roller 214 and the movable pressure plate 38 after they are reset to the initial state.

[0029] Thus, by cooperating with the two convex plates 31 and the concave plate 36, when the user performs a lamination process on the felt cloth, the stability of the flattening roller 214 can be ensured, and the stability of the movable pressing plate 38 after the position is changed can also be ensured.

[0030] At the same time, when the user presses the felt cloth at some parts with smaller angles, the user only needs to insert the rounded ends of the two movable pressing plates 38 into the angle. Under the blocking effect of the angle, the two movable pressing plates 38 will rotate with the fixed axis 37 as the fulcrum. During the process, the arc spring 310 is compressed and the rubber layer 39 is stretched. As the two movable pressing plates 38 rotate, the angle between the movable pressing plates 38 will also become smaller, so as to automatically adapt to the angle parts in the car frame, so as to better press the felt cloth at these parts.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
