Abstract
Description
Technical Field
[0001] This utility model relates to the field of hollow guide rail filling technology, and in particular to a hollow guide rail foam filling device. Background Technology
[0002] Hollow guide rails require foamed resin to fill their gaps. The foamed resin absorbs vibration waves, making the guide rail quiet. Traditional foamed resin filling methods usually use a linear motion, which results in the foamed resin forming a straight line of filling material in the guide rail. In cross-sectional view, this filling method appears as a dotted structure. When the gaps between the hollow structures in the hollow guide rail are large or the angle of the gap head is large, this linear filling method often cannot fully fill the hollow structure after the foamed resin expands, thus affecting the quietness of the guide rail. In addition, due to the existence of gaps, the foamed resin is also prone to falling off, further weakening the quietness and durability of the guide rail. Utility Model Content

[0013] according to Figures 1-6As shown, a hollow guide rail foam filling device includes a conveyor frame 1 and a hollow guide rail. The conveyor frame 1 is equipped with a spraying device 2 and an end cap device, with the end cap device positioned in front of the spraying device 2. The conveyor frame 1 includes a pair of symmetrically arranged side plates 12, with support legs at the bottom of each side plate 12. A plurality of conveying wheels 11 are arranged between the side plates 12. The conveying wheels 11 are driven by a drive motor to rotate, thus conveying the hollow guide rail. The drive motor is periodically connected to the conveying wheels 11, and by driving the conveying wheels 11 at corresponding positions, the hollow guide rail at those positions can be conveyed. The spraying device 2 includes a portal frame 21, with the bottom of the portal frame 21 positioned on both side plates. On 12, an L-shaped connecting plate 22 is provided on the top of the portal frame 21. A lifting cylinder 23 is provided on the L-shaped connecting plate 22. The movable end of the lifting cylinder 23 passes through the L-shaped connecting plate 22 and is connected to a discharge chute 24. A nozzle 25 is provided at the bottom of the discharge chute 24. The L-shaped connecting plate 22 is rotatably connected to the top of the portal frame 21. A rotary motor 26 is provided on the rear side of the portal frame 21. The movable end of the rotary motor 26 passes through the portal frame 21 and is connected to a rotating block 27. A connecting rod 28 is provided between the rotating block 27, the L-shaped connecting plate 22, and the portal frame 21. The connecting rod 28 and the connecting points of the rotating block 27, the L-shaped connecting plate 22, and the portal frame 21 are all eccentrically connected.
[0014] The end cap device includes a lifting baffle 3, which is disposed between two side plates 12. The side plates 12 have guide grooves that cooperate with the lifting baffle 3 to make its lifting movement more stable. A baffle cylinder 31 is disposed at the bottom of the lifting baffle 3, mounted on a support leg. The movable end of the baffle cylinder 31 is located at the bottom of the lifting baffle 3, controlling its lifting movement. An end cap placement frame 4 is also disposed on the side plate 12, and a [missing information - likely a design feature or feature] is disposed at the top of the end cap placement frame 4. The end cap has a feed inlet 41. The end cap is rectangular and made of an elastic material, which also provides some protection for the end of the hollow guide rail. The end cap has a groove that matches the cross-section of the hollow guide rail. Two end caps are placed back-to-back with their grooves facing outwards as a group. They are placed into the end cap channel 42 through the feed inlet 41. The end cap placement rack 4 has the end cap channel 42. A support plate 43 is also provided between the side plates at the bottom of the outlet of the end cap channel 42. The end cap placement rack 4 also has a support plate 43 on one side. A telescopic cylinder 44 is provided, and a concave baffle 45 is provided on the movable end of the telescopic cylinder 44. The concave baffle 45 is connected to the end cap channel 42. By driving the concave baffle 45 with the telescopic cylinder 44, the end caps in the end cap channel 42 can be separated for unloading and pre-loading. During the telescopic cylinder 44 controls the concave baffle 45 to extend and retract, the end plate in the groove of the concave baffle 45 can fall onto the support plate 43, and the end plate above the concave baffle 45 is placed in the groove of the concave baffle 45. The purpose of setting the end cap device is that after the foaming resin expands, the edge is usually arc-shaped, which means that the foaming resin at both ends of the hollow guide rail cannot be completely filled after expansion. In order to fill as much as possible and reduce gaps, the foaming resin should be placed as close as possible to the ends of the guide rail when spraying. However, this may cause the foaming resin to flow out of the hollow guide rail after expansion. Therefore, the end cap can prevent the foaming resin from flowing out and assist the expansion of the foaming resin, so that the expanded foaming resin can fill the ends of the hollow guide rail as much as possible.
[0015] The lifting baffle 3 and the end cover placement frame 4 are spaced apart, and the distance between them is slightly greater than the length of the hollow guide rail.
[0016] The discharge trough 24 is provided with a feed inlet 29, and a conveying pipe is connected to the feed inlet 29. The conveying pipe is connected to an external resin storage tank, allowing the foaming resin to enter the discharge trough 24 and then be sprayed through the nozzle 25.
[0017] In practical use, the hollow guide rail moves on the conveyor frame 1, passing sequentially through the end cap placement frame 4, the lifting baffle 3, and the spraying device 2. During the installation of the end caps, the top of the first hollow guide rail is blocked by the lifting baffle 3. Then, the end cap placement frame 4 controls the end cap to fall onto the support plate 43. The second hollow guide rail then moves, with its front end pressing against the rear end of the first hollow guide rail. At this point, the end caps between the first and second hollow guide rails are respectively placed on the front end of the second hollow guide rail and the rear end of the first hollow guide rail. Then, the lifting baffle 3 descends, allowing the first hollow guide rail to proceed with subsequent filling. After the second hollow guide rail reaches the lifting baffle 3, it becomes the new first hollow guide rail, and the end caps are installed with the following hollow guide rails. This cycle continues.
[0018] During the spraying process of the spraying device 2, the rotary motor 26 drives the rotating block 27 to rotate, and the connecting rod 28 drives the L-shaped connecting plate 22 to swing back and forth, thereby driving the nozzle 25 to swing back and forth, spraying the hollow guide rail below, so that the foaming resin forms an S-shaped path in the hollow of the hollow guide rail. In this process, the swaying amplitude of the nozzle 25 itself is small due to the setting of the connecting rod structure, and the range of foaming resin falling can be controlled by adjusting the height of the nozzle 25 by the lifting cylinder 23.
[0019] This design is ingenious. The spraying device uses a rotary motor and linkage mechanism to allow the nozzle to swing back and forth, spraying the foaming resin along an S-shaped path in the hollow guide rail. This effectively improves the filling rate of the foaming resin in the hollow guide rail after expansion. The end cap device ensures that the foaming resin can completely fill both ends of the hollow guide rail after expansion, assisting the expansion of the foaming resin and ensuring the filling effect at both ends of the guide rail.
[0020] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
