Abstract
Description
Technical Field
[0001] This utility model relates to the field of edge banding equipment technology, specifically a paddle edge banding device. Background Technology
[0002] The paddleboard has an inner skin and an outer skin. The inner skin is used for inflation, and the outer skin is used to protect the inner skin. The outer skin includes a cover and side strips. The cover is located on the upper surface of the paddleboard, and the side strips are located on the sides of the paddleboard. After the cover and side strips are installed, hot-melt edge banding is needed to seal the seam between the cover and the side strips. Currently, during the sealing process, workers need to hold a hot air gun while simultaneously holding a handwheel and rotating it around the paddleboard to cover the seam between the cover and the side strips with the hot-melt edge banding. However, because workers need to hold the hot air gun for a long time while constantly rolling the hot-melt edge banding with the handwheel, the labor intensity is high. Furthermore, the paddleboard is placed on the workbench without any positioning measures. If the rolling force is too large, the paddleboard is prone to movement. When the movement is significant, the position of the paddleboard needs to be readjusted, making it impossible to achieve continuous, stable, and efficient edge sealing. Utility Model Content
[0003] The purpose of this utility model is to provide a paddle sealing device, which aims to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: the paddle sealing device includes an operating table: The upper surface of the operating table is provided with a mounting groove, and a driving sprocket and several driven sprockets are arranged inside the mounting groove. The driving sprocket and several driven sprockets are driven by a chain, and the driving sprocket and several driven sprockets rotate in the same direction. The bottom of the operating platform is equipped with a power mechanism, which is used to drive the drive sprocket to rotate. The operating table is provided with a placement plate, and the interior of the placement plate is provided with a receiving groove, into which the paddleboard can be placed; A fixing plate is provided on the chain, and a heater is provided on the fixing plate. When the chain moves, it can drive the heater to move around the outside of the paddle plate.
[0005] Preferably, the side of the placement plate has a notch that communicates with the receiving groove, and the bottom surface of the notch is located below the bottom surface of the receiving groove.
[0006] Preferably, the lower surface of the placement plate is provided with a stud, the outer surface of the stud is provided with a fixing plate, the operating table is provided with a through groove, the lower end of the stud can pass through the through groove, and a nut is threaded onto the stud.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0018] like Figure 1-6 As shown, a paddle sealing device includes an operating table 3: The upper surface of the operating table 3 is provided with a mounting groove. Inside the mounting groove is a driving sprocket 4 and several driven sprockets 5. The driving sprocket 4 and several driven sprockets 5 are driven by a chain 6. The driving sprocket 4 and several driven sprockets 5 rotate in the same direction. A power mechanism 7 is provided at the bottom of the control panel 3, which is used to drive the drive sprocket 4 to rotate; The operating table 3 is provided with a placement plate 8, and the interior of the placement plate 8 is provided with a receiving groove 9, into which the paddle 1 can be placed; A fixing plate 10 is provided on the chain 6, and a heater 11 is provided on the fixing plate 10. When the chain 6 moves, it can drive the heater 11 to move around the outside of the paddle plate 1.
[0019] The upper and lower surfaces of the paddleboard 1 are covered with skin, and the sides of the paddleboard 1 are also covered with edge strips. There are seams between the edge strips on the sides and the skins on the upper and lower surfaces. The seams need to be sealed by hot-melt edge strips 2. This process is also called edge sealing of paddleboard 1.
[0020] When sealing the edges of the paddle plate 1, it is necessary to first place the paddle plate 1 into the receiving groove 9. The shape of the receiving groove 9 is similar to that of the paddle plate 1. The paddle plate 1 needs to be placed in the receiving groove 9 in a deflated state. Then, air is injected into the paddle plate 1 through the air inlet on the paddle plate 1, causing the paddle plate 1 to inflate. After inflating, the paddle plate 1 will not be stuck in the receiving groove 9. The operator can remove the paddle plate 1 from the receiving groove 9 without deflating it. After the paddle plate 1 is placed, the hot-melt edge strip 2 is installed at the joint between the skin and the edge strip. The hot-melt edge strip 2 has its own adhesive layer, so it can be fixed to the joint between the skin and the edge strip by its own adhesive force. Then, the power mechanism 7 is started. The power mechanism 7 includes a motor, a reducer, and a commutator. The motor drives the drive sprocket 4 to rotate through the reducer and the commutator. When the drive sprocket 4 rotates, the other driven sprockets 5 will also rotate under the action of the chain 6. At the same time, the chain 6 will move along the drive sprocket 4 and the driven sprockets 5. As wheel 5 moves, chain 6 moves, driving fixed plate 10 to move. Fixed plate 10 can then move heater 11 above. A power socket can be pre-installed above the device. Heater 11 is a hot air heater and can be powered from the pre-installed power socket. Heater 11 blows hot air onto the hot-melt side strip 2. Heater 11 moves slowly with chain 6 to ensure that the hot-melt side strip 2 is effectively heated. As heater 11 moves with chain 6, the distance between the air outlet of heater 11 and the hot-melt side strip 2 is approximately the same to improve heating accuracy. The operator uses handwheel 21 to repeatedly roll the heated hot-melt side strip 2 to ensure that the hot-melt side strip 2 is firmly connected to the skin and side strip. The operator also needs to move around paddle 1 with heater 11 to roll the hot-melt side strip 2 at various positions.
[0021] If there is excessive twisting between the wire of heater 11 and the socket above, the wire of heater 11 can be loosened from the socket above. After the twisting is corrected, the two can be reinstalled together.
[0022] After processing the hot-melt edge strip 2 on one side, the paddle 1 is removed from the receiving groove 9, then rotated 180° and pressed back into the receiving groove 9 to facilitate the installation of another hot-melt edge strip 2.
[0023] Furthermore, a notch 12 is provided on the side of the placement plate 8, which is connected to the receiving groove 9. The bottom surface of the notch 12 is located below the bottom surface of the receiving groove 9, and the notch 12 facilitates the lifting of the paddle plate 1 in the receiving groove 9.
[0024] Furthermore, a stud 13 is provided on the lower surface of the placement plate 8, and a fixing plate 14 is provided on the outer surface of the stud 13. A through groove is provided on the operating table 3, and the lower end of the stud 13 can pass through the through groove. A nut 15 is threaded onto the stud 13. The placement plate 8 can be fixed to the operating table 3 through the stud 13, the nut 15 and the fixing plate 14.
[0025] When maintenance is required on the drive sprocket 4, driven sprocket 5, and chain 6, the nut 15 needs to be unscrewed from the stud 13, and then the placement plate 8 is lifted upwards to expose the top of the operating table 3. At this time, maintenance can be performed on the drive sprocket 4, driven sprocket 5, and chain 6, including adding lubricating grease, cleaning dirt, and tightening the chain 6.
[0026] Furthermore, a vertical rod 16 is provided on the fixed plate 10, and a top rod 17 is rotatably connected to the vertical rod 16. A compressible rubber ring 18 is provided between the vertical rod 16 and the top rod 17. A sleeve 19 is provided at the upper end of the vertical rod 16, and the heater 11 is located inside the sleeve 19. The rubber ring 18 is in a compressed state. When the top rod 17 rotates, the rubber ring 18 can apply resistance to the top rod 17. When the rotation of the top rod 17 is actively stopped, the top rod 17 will stay in the adjusted position. When the paddle plate 1 is placed into the receiving groove 9, or when the paddle plate 1 is removed from the receiving groove 9, in order to avoid the heater 11 affecting the removal or placement of the paddle plate 1, the heater 11 can be moved away in advance by rotating the top rod 17.
[0027] Furthermore, a clamping bolt 20 is provided on the outside of the sleeve 19. The clamping bolt 20 can fix the heater 11 inside the sleeve 19. The position of the heater 11 can be adjusted inside the sleeve 19 so as to control the distance between the air outlet of the heater 11 and the paddle 1. After the adjustment of the heater 11 is completed, the heater 11 can be fixed inside the sleeve 19 by tightening the clamping bolt 20.
