Description

Technical field:

[0002] The utility model relates to an aluminum strip pressing device. Background technology:

[0004] After rolling, aluminum strips are rolled into coils for placement. When rolling aluminum strips, due to the thinness of some aluminum strips, the head of the aluminum strip lacks compression during the rolling process, so that the head of the aluminum strip cannot fully fit with the surface of the rolling roller, which causes loose layers when the aluminum strip is rolled, affecting the normal rolling operation. Therefore, it is necessary to improve this technical problem, and this case is born. Utility model content:

[0006] The utility model makes improvements on the problems existing in the above-mentioned prior art, that is, the technical problem to be solved by the utility model is to provide an aluminum strip clamping device with reasonable design to ensure that the head of the aluminum strip fits the surface of the curling roller when curling.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an aluminum strip pressing device, including a curling roller, a lower pressing roller arranged parallel to the top of the curling roller and capable of swinging up and down, a support rod arranged parallel to the front side of the lower pressing roller, the support rod swings up and down synchronously with the lower pressing roller, a connecting rope is arranged on the support rod, and the end of the connecting rope away from the support rod is connected to a magnet pressing block for pressing the head of the aluminum strip against the outer surface of the curling roller, and the magnet pressing block is connected to the curling roller by magnetic adsorption.

[0008] Furthermore, a ring is provided at one end of the connecting rope close to the support rod, and the ring is sleeved on the outside of the support rod and can slide along the support rod.

[0009] Furthermore, the length of the connecting rope is less than three quarters of the circumference of the winding roller.

[0010] Furthermore, it also includes a pair of swing arms arranged on the left and right sides of the lower pressure roller, the swing arms are driven by the swing mechanism to swing up and down, and the lower pressure roller and the support rod are both installed between the pair of swing arms.

[0011] Compared with the prior art, the utility model has the following effects: the utility model has a simple and reasonable structural design. A connecting rope and a magnet pressing block are arranged on the front side of the lower pressure roller. After the head of the aluminum strip passes through between the lower pressure roller and the curling roller, the magnet pressing block is pressed on the head of the aluminum strip. The magnet pressing block and the curling roller are connected together by magnetic adsorption, so that the head of the aluminum strip is pressed tightly against the outer surface of the curling roller, ensuring that the head of the aluminum strip fits with the surface of the curling roller during curling, which facilitates the normal curling of the aluminum strip and effectively avoids the phenomenon of loose layers when the aluminum strip is curled.

[0014] Figure 2 It is a schematic diagram of the top view of the structure of an embodiment of the utility model. Specific implementation method:

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0017] In the description of the present invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0018] like Figures 1-2 As shown, the utility model is an aluminum strip clamping device, which is improved on the existing strip curling equipment. The existing curling equipment includes a curling roller 1 made of metal material, and a lower pressing roller 2 arranged parallel to the curling roller 1 and capable of swinging up and down. The curling roller 1 curls the aluminum strip 8, and the lower pressing roller 2 is used to press the aluminum strip on the curling roller 1. A support rod 3 is arranged parallel to the front side of the lower pressing roller 2, and the support rod 3 swings up and down synchronously with the lower pressing roller 2. The specific improvement of the aluminum strip clamping device is that a connecting rope 4 is arranged on the support rod 3, and a magnet pressing block 5 is connected to the end of the connecting rope 4 away from the support rod 3. The magnet pressing block 5 is used to press the head 6 of the aluminum strip on the outer surface of the curling roller 1, and the magnet pressing block 5 is connected to the curling roller 1 by magnetic adsorption. During operation, the curling roller 1 and the lower pressure roller 2 work normally. After the aluminum strip 8 passes between the lower pressure roller 2 and the curling roller 1, the head 6 of the aluminum strip is located at the front side of the lower pressure roller 2. Then, the magnet pressing block 5 is manually pressed on the side of the aluminum strip head 6 away from the curling roller. The magnet pressing block 5 and the curling roller 1 are connected together by magnetic adsorption, that is, the aluminum strip head 6 is clamped between the magnet pressing block 5 and the outer surface of the curling roller 1, so that the aluminum strip head is pressed tightly against the outer surface of the curling roller 1 to ensure that the aluminum strip head and the surface of the curling roller are in contact during curling; then the magnet pressing block 5 rotates synchronously with the curling roller 1 to the rear side and lower side of the lower pressure roller 2. When the connecting rope 4 is in a completely straightened state, the magnet pressing block 5 no longer rotates with the curling roller 1, and the magnet pressing block is located below the aluminum strip body, and the curling roller can curl the aluminum strip normally; finally, the magnet pressing block is manually pulled down through the connecting rope, because the magnet pressing block is no longer needed after normal curling.

[0019] In this embodiment, a ring 7 is provided at one end of the connecting rope 4 close to the support rod. The ring 7 is sleeved on the outside of the support rod 3 and can slide along the support rod 3 to facilitate the movement of the magnet pressing block along the support rod. Especially after the curling operation is carried out normally, the position of the connecting rope can be slid to the edge of the support rod.

[0020] In this embodiment, the length of the connecting rope 4 is slightly smaller than three quarters of the circumference of the curling roller 1, so as to ensure that the position of the magnet pressing block 5 is located below the rear side of the lower pressing roller when the connecting rope 4 is stretched to a straightened state, that is, the magnet pressing block is located below the rear side of the curling corner of the aluminum strip, so as to avoid the connecting rope being too long, which causes the magnet pressing block to affect the curling of the aluminum strip.

[0021] In this embodiment, a pair of swing arms 9 are further included on the left and right sides of the lower pressure roller 2, and the swing arms 9 are driven by a swing mechanism to swing up and down, and the lower pressure roller 2 and the support rod 3 are both installed between the pair of swing arms 9. It should be noted that the structure of the swing arm and the corresponding swing mechanism are the same as those of the existing curling equipment, and the specific structure and working principle will not be repeated here.

[0022] If the present invention discloses or involves components or structures that are fixedly connected to each other, then, unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (for example, connection using bolts or screws), and can also be understood as: a non-detachable fixed connection (for example, riveting, welding). Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by one-piece molding using a casting process) (except where it is obviously impossible to use an one-piece molding process).

[0023] In addition, unless otherwise stated, the terms used to indicate positional relationships or shapes in any of the technical solutions disclosed in the above utility model include states or shapes that are approximate, similar or close thereto.

[0024] Any component provided by the utility model can be assembled from multiple separate components, or can be a separate component manufactured by an integrated molding process.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the relevant field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for protection of the utility model.
