Description
Technical Field
[0001] This utility model relates to the field of salt field plastic covering technology, and in particular to a variable channel floating roll plastic covering lifting button rail inserter. Background Technology
[0002] During the process of floating roll plastic covering in Yantian, the two sides of the plastic sheet need to be adjusted frequently when entering the rail. Each time the floating roll is used, the position of the lifting button wrapped around the float is relatively large when the plastic sheet is rolled up, and there are cases where it is not within the range of the rail. This makes it difficult for the lifting button to enter the rail during plastic covering, and manual adjustment is required. This is not only time-consuming and labor-intensive for the staff, but also affects the efficiency of plastic covering. Utility Model Content
[0003] To address the problems existing in the prior art, this utility model provides a variable channel floating roll plastic sheeting hanging button rail inserter.
[0004] The variable channel floating roll plastic sheeting lifting button rail inserter provided by this utility model adopts the following technical solution:
[0005] A variable channel float roll plastic cover lifting button track inserter includes two symmetrically arranged upper and lower rails and two symmetrically arranged lower and lower rails. A gap is provided between the rails for the lifting button body to pass through and move, and a similar gap is provided between the rails for the lifting button body to pass through and move. The rails are inclined and their ends away from the float are close to each other. A gap is provided between the end of the rail near the rail and the rail for the lifting button head to pass through. A track separation plate for closing the gap is hinged to the end of the rail. The track separation plate is elastically abutted against the rail by a return spring. A guard plate is fixed to the top surface of the upper rail and the rail, and a guard plate is fixed to the bottom surface of the lower rail and the rail. The guard plate includes a main plate and a lifting button release guide plate located at the end of the main plate near the float. The upper and lower lifting button release guide plates are bent in opposite directions to form a cantilever edge.
[0006] By adopting the above technical solution, the rail entry device uses two different tracks to enter and exit at different positions, with the exit track being further back, ensuring that no personnel operation is required for the next rail entry; the entry track is wide and the exit track is narrow. By installing an automatically operating track separation plate inside the rail entry device, the purpose of ensuring that the lifting button is wrapped around the outermost fixed area of the float during the float recovery process is achieved, so that the lifting button enters the track accurately and avoids derailment.
[0007] Optionally, the return spring is a tension spring, which is connected between the side of the track separation plate near the entry track and the side of the derailment track near the entry track.
[0008] By adopting the above technical solution, the tension spring elastically pulls the track separation plate to move closer to the entry track. The tension spring is easy to source, has stable performance, and low operating cost.
[0009] Optionally, the return spring is a torsion spring installed at the hinge point of the track separation plate, which has an elastic tendency to cause the end of the track separation plate to elastically abut against the track.
[0010] By adopting the above technical solution, the torsion spring elastically drives the track separation plate to move closer to the entry track. The torsion spring is easy to obtain, has stable performance, and low operating cost.
[0011] Optionally, the return spring is a tension spring, which is located on the outside of the guard plate. An anti-disengagement hook is fixed to the outside of the main plate. A sliding hole is opened on the main plate corresponding to the position of the track separation plate. A positioning pin is fixed on the track separation plate and slides through the sliding hole. The return spring is connected between the positioning pin and the anti-disengagement hook.
[0012] By adopting the above technical solution, the return spring is located on the outside, which not only reduces the unexpected impact on the movement of the button, but also facilitates the installation and replacement of the return spring.
[0013] Optionally, the lower release guide plate has a longer extension than the upper release guide plate.
[0014] By adopting the above technical solution, it is possible to more comprehensively receive and guide the pontoons wrapped around the lower buoy.
[0015] Optionally, the lower release guide plate is detachably connected to the main board via connecting bolts.
[0016] By adopting the above technical solution, it is easy to reduce the overall weight of the guard plate, and at the same time, it is easy to replace the release guide plate of the lifting button in a timely and convenient manner after wear.
[0017] Optionally, the guard plate also includes a hook recovery guide plate located at the end of the main board away from the float, with the upper and lower hook recovery guide plates bent in opposite directions to form a lifting edge.
[0018] By adopting the above technical solution, it is easier to guide the lifting button to perform the retraction movement more effectively.
[0019] Optionally, reinforcing ribs are fixed to the outer side of the main board along the direction of movement of the plastic fabric.
[0020] By adopting the above technical solution, the reinforcing ribs effectively enhance the strength and stability of the protective plate structure.
[0021] In summary, this utility model has at least one of the following beneficial technical effects:
[0022] The entry device uses two different tracks to enter and exit at different positions, with the exit track located further back, ensuring that no human intervention is required for the next entry.
[0023] With a wide entry rail and a narrow exit rail, an automatically operating rail separation plate is installed inside the rail inserter to ensure that the lifting button is wound around the outermost fixed area of the float during the float recovery process, ensuring accurate insertion of the lifting button and preventing derailment.

[0029] The following is in conjunction with the appendix Figure 1 -Appendix Figure 4 The present invention will be described in further detail below.
[0030] This utility model discloses a variable channel floating roll plastic sheeting hanging button rail inserter. Example
[0031] Reference Figure 1 and Figure 2 The variable channel floating roll plastic cover hanging button rail inserter acts on multiple hanging buttons 1. The rail inserter includes two rail inserting tracks 2 arranged symmetrically in the upper and lower positions and two rail exiting tracks 3 arranged symmetrically in the upper and lower positions. A gap is provided between the two rail inserting tracks 2 to accommodate the body of the hanging button 1 to pass through and move. A gap is also provided between the two rail exiting tracks 3 to accommodate the body of the hanging button 1 to pass through and move.
[0032] Reference Figure 1 and Figure 2Both the entry track 2 and the exit track 3 are inclined and their ends away from the pontoon are close to each other. There is a gap between the end of the entry track 2 away from the pontoon and the end of the exit track 3 away from the pontoon for the head of the lifting button 1 to pass through. Both the end of the entry track 2 away from the pontoon and the end of the exit track 3 away from the pontoon are fixedly connected to a slide rail connecting rod 4 arranged along the moving direction of the plastic cloth. The slide rail connecting rod 4 is used to connect with the slide rails on both sides of the salt field.
[0033] Reference Figure 1 and Figure 2 A track separation plate 5 is rotatably mounted on the end of the derailment track 3 away from the buoy via a pin. The movable end of the track separation plate 5 rests on the entry track 2, thereby closing the gap between the derailment track 3 and the entry track 2. A return spring 6 is connected between the side of the track separation plate 5 near the entry track 2 and the side of the derailment track 3 near the entry track 2. In this embodiment, the return spring 6 is a tension spring; in other examples, a torsion spring can also be installed at the pin as the return spring 6. When the button 1 passes through this gap, it pushes the track separation plate 5 to move away from the entry track 2; after the button 1 passes through this gap, under the elastic drive of the return spring 6, the track separation plate 5 moves in the opposite direction to return to its original position, thereby closing the gap.
[0034] Reference Figure 1 and Figure 2 A guard plate 7 is fixed to the top surface of the upper entry rail 2 and the lower exit rail 3, and a guard plate 7 is fixed to the bottom surface of the lower entry rail 2 and the lower exit rail 3. The guard plate 7 includes a main plate 70 and a release guide plate 71 for the lifting button located near the end of the main plate 70 near the float. The upper and lower release guide plates 71 are bent in opposite directions to form a lifting edge. The bending length of the lower release guide plate 71 is greater than that of the upper release guide plate 71, so as to more comprehensively receive and guide the lifting button 1 wrapped on the lower float.
[0035] When it is necessary to cover the salt field with plastic before it rains, the traction device moves one end of the plastic sheet forward to cover the salt field, and then moves the hanging button 1 on the plastic sheet into the space between the upper and lower guard plates 7. Under the guidance of the track 2, the hanging button 1 pushes open the track separation plate 5 and moves out to the track on both sides of the salt field.
[0036] When the plastic sheet is rolled up, the float rotates to roll up the plastic sheet, and the lifting button 1 moves with the plastic sheet. At this time, since the track separation plate 5 is in a stable closed state, the lifting button 1 can only move along the outside of the track separation plate 5 to the outside of the derailment track 3, and under the guidance of the derailment track 3, it moves to both ends of the float, so that the lifting button 1 is uniformly wrapped around the outer end of the float. When the plastic sheet is covered again, the lifting button 1 will be within the track entry range to avoid manual track entry.
[0037] The rail feeder uses two different tracks for entry and exit at different positions, with the exit track positioned further back to ensure that no manual operation is required for the next rail feed. It features a wide entry track and a narrow exit track. By installing an automatically operating track separation plate 5 inside the rail feeder, the lifting button 1 is kept within the outermost fixed area of the float during the float recovery process, ensuring accurate rail feed and preventing derailment. Example
[0038] Reference Figure 3 and Figure 4 The difference between this embodiment and Embodiment 1 is that in this embodiment, the return spring 6 is located on the outside of the guard plate 7, and an anti-disengagement hook 8 is fixedly connected to the outside of the main plate 70. A sliding hole 700 is provided on the main plate 70 corresponding to the position of the track separation plate 5. A positioning pin 9 is fixed on the track separation plate 5 and slides through the sliding hole 700. The return spring 6 is a tension spring, which is connected between the positioning pin 9 and the anti-disengagement hook 8. The return spring 6 has an elastic tendency to drive the track separation plate 5 towards the direction of the entry track 2. The location of the return spring 6 on the outside not only reduces the accidental impact on the movement of the lifting button 1, but also facilitates the installation and replacement of the return spring 6.
[0039] Reference Figure 3 and Figure 4 In this embodiment, the lower release guide plate 71 is detachably connected to the main board 70 via connecting bolts 73, which reduces the overall weight of the guard plate 7 and facilitates timely and convenient replacement of the release guide plate 71 after wear. The guard plate 7 also includes a release guide plate 72 located at the end of the main board 70 away from the float. The upper and lower release guide plates 72 are bent in opposite directions to form a cantilever, which helps to more effectively guide the release button 1 to perform the retrieval movement. A reinforcing rib 74 is also fixed to the outer side of the main board 70 along the direction of plastic fabric movement. The reinforcing rib 74 enhances the structural strength and stability of the guard plate 7.
[0040] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
