[0022] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] like Figures 1-3 This utility model provides a waste edge winding device, including a waste edge winding machine and a waste material elevator. The waste edge winding machine has a fixed guide groove 1 at its material outlet. The waste material elevator includes a movable hopper 2 and a lifting mechanism 21 for driving the movable hopper 2 to move between a low receiving position and a high receiving position. A bridging unit is provided at the material outlet of the fixed guide groove 1 to connect it with the movable hopper 2. More specifically, the bridging unit is used to connect the fixed guide groove 1 with the movable hopper 2 at the low receiving position, so as to seal the gap between the fixed guide groove 1 and the movable hopper 2, prevent waste edges, debris, etc. from entering the foundation pit through the gap, effectively improve the working stability and reliability of the waste edge winding device, and also reduce the labor intensity and danger of workers cleaning the foundation pit.

[0024] The aforementioned lifting mechanism 21 can be in the form of a chain, wire rope, or other drive motor, which will not be described in detail here.

[0025] In one embodiment, such as Figures 2-4 The bridge unit includes a swing shaft 33 and a bridge plate 31. The swing shaft 33 is located at the material outlet of the fixed guide trough 1 and its axis is parallel to the width direction of the fixed guide trough 1. The bridge plate 31 is located at the material outlet of the fixed guide trough 1 and one end is connected to the swing shaft 33. The other end of the bridge plate 31 can swing between the working position and the lifting position. In the working position, the bridge plate 31 extends into the movable hopper 2 located at the receiving position. In the lifting position, the bridge plate 31 stands at the material outlet of the fixed guide trough 1.

[0026] In one embodiment, the bridge unit is a follow-up bridge unit, which can effectively save equipment and operating costs and has very high operational reliability. When the bridge plate 31 is in the working position, it can move with the movement of the movable hopper 2. When the movable hopper 2 moves from the low receiving position to the high handover position under the action of the lifting mechanism 21, it can drive the bridge plate 31 to swing towards the lifting position.

[0027] For the following movement of the aforementioned bridge plate 31, a follower drive component can be installed on the movable hopper 2 to drive the bridge plate 31 to move. Preferably, as follows... Figure 2 The movable hopper 2 has a first roller 32 at its material inlet end. The axis of the first roller 32 is parallel to the axis of the swing shaft 33, and the lifting trajectory of the first roller 32 intersects the swing trajectory of the bridge plate 31. When the movable hopper 2 is in the low receiving position, the bridge plate 31 is above the first roller 32, for example, in the raised or working position. When the movable hopper 2 moves from the low receiving position to the high receiving position under the action of the lifting mechanism 21, the first roller 32 interferes with the bridge plate 31, causing the bridge plate 31 to swing towards the raised position. The first roller 32 is rotatably mounted at the material inlet end of the movable hopper 2. The first roller 32 enables the bridge plate 31 to follow the movement, and the roller 32 has rolling contact with the bridge plate 31, resulting in low friction and significantly reducing wear and noise between the equipment.

[0028] When the bridge plate 31 is in the raised position, it interferes with the falling scrap roll, allowing it to swing towards the working position under the push of the scrap roll, but this will result in a significant impact. As a preferred solution, such as... Figures 2-4 The bridge unit further includes a reset guide plate 34, which is connected to the swing shaft 33 and located to the side of the fixed guide groove 1. A second roller 35 is provided on the outer wall of the movable hopper 2. The axis of the second roller 35 is parallel to the axis of the swing shaft 33, and the descent trajectory of the second roller 35 intersects the swing trajectory of the reset guide plate 34. When the movable hopper 2 moves from the high material receiving position to the low material receiving position, the second roller 35 contacts and pushes the reset guide plate 34, thereby causing the bridge plate 31 to swing downwards, allowing it to swing from the raised position to the working position, achieving the follow-up reset of the bridge plate 31, thus improving the working reliability of the bridge unit.

[0029] Understandably, the reset guide plate 34 has a downward stroke end and an upward stroke end. When the bridge plate 31 swings from the working position to the raised position, it can drive the reset guide plate 34 to swing from the downward stroke end to the upward stroke end. When the reset guide plate 34 is at the upward stroke end, it is located on the downward trajectory line of the second roller 35, so it can be pushed by the second roller 35. When the reset guide plate 34 is pushed by the second roller 35 to swing from the upward stroke end to the downward stroke end, it can drive the bridge plate 31 to swing from the raised position to the working position, thereby realizing the reset of the bridge plate 31.

[0030] As an optimization, such as Figure 2 and Figure 4 The reset guide plate 34 has two pieces and is respectively disposed on both sides of the bridge plate 31 to provide more stable reset guidance.

[0031] In another embodiment, the bridge plate 31 may also be configured with a swing drive device to drive the bridge plate 31 to swing between the working position and the raised position. The swing drive device includes, but is not limited to, cylinders / hydraulic cylinders.

[0032] In one embodiment, the bridge unit further includes a positioning locking mechanism 36 for positioning and constraining the bridge plate 31 in the working position, which can further improve the working reliability of the bridge unit, for example, it can prevent it from being accidentally lifted during material receiving.

[0033] In a specific implementation plan, such as Figure 5 The positioning and locking mechanism 36 includes a positioning disc 361 and a locking roller 362. The axis of the locking roller 362 is parallel to the axis of the swing shaft 33. The locking roller 362 is mounted on the surrounding base via an elastic structure 363, and the elastic direction is arranged radially along the locking roller 362. The positioning disc 361 is fixedly connected to the swing shaft 33. The edge of the positioning disc 361 is provided with a constraint groove. The constraint groove satisfies the following conditions: in the working position, the locking roller 362 is engaged in the constraint groove, and when an external force (such as the first roller 32 on the movable hopper 2) drives the bridge plate 31 to swing to the raised position, the locking roller 362 can separate from the constraint groove. Optionally, as shown in the figure... Figure 5 The elastic structure 363 includes a guide sleeve, a spring, and a base mounted on the surrounding foundation. The base is provided with a guide post. The guide sleeve is movably fitted on the guide post. The spring is fitted on the guide post and its two ends abut against the guide sleeve and the base, respectively. The locking roller 362 is rotatably mounted on the guide sleeve, and the axial direction of the guide post is arranged along the radial direction of the locking roller 362.

[0034] like Figure 5The aforementioned constraint groove can be an arc-shaped groove with rounded corners at the opening. This reduces the difficulty of separating the locking roller 362 from the constraint groove, improves the smoothness of the separation action, and also reduces the frictional wear of the equipment.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
