Description

Technical Field

[0001] The utility model relates to a sleeve conveying mechanism suitable for sleeves of different lengths. Background Art

[0002] Aluminum coil is an important basic material for the development of my country's national economy. In the normal industrial production process, after the production and processing of aluminum sheets and strips are completed, aluminum sheet and strip manufacturers must roll up a large number of finished products and store them in the workshop as finished products or semi-finished products or transport them to users. In the process of rolling aluminum sheets and strips, a core shaft sleeve is usually placed at the core of the roll, which is used as the basic core roll for rolling aluminum sheets and strips. This is the aluminum core sleeve.

[0003] The aluminum coil is wrapped around the aluminum core sleeve in the middle. Different lengths of the sleeve are required to accommodate different aluminum coils. However, during the transportation process, sleeves of different lengths cannot be pushed to the appropriate positions due to the consistent pushing displacement, which easily leads to positional displacement. At this time, manual re-pushing is required, which wastes manpower, affects efficiency and is prone to stacking with subsequent rolled-down sleeves, which urgently needs to be improved. Utility Model Content

[0004] In view of the deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a sleeve conveying mechanism suitable for sleeves of different lengths, which is not only simple and reasonable in structure, but also convenient and stable.

The support rollers are rotatably connected to the U-shaped frame via a rotating shaft, and the bottom of the U-shaped frame is fixedly connected to the top of the pushing frame via a support seat.

[0008] Furthermore, a guide plate extending obliquely inwardly is fixedly provided on one side of the sleeve conveying frame close to the short push plate.

[0009] Furthermore, the bottom of the cylinder is fixedly connected to a support plate, the support plate is fixedly connected to the sleeve conveying frame, and the sleeve conveying frame is provided with a notch for the cylinder to extend and retract.

[0010] Furthermore, a shift rod is rotatably connected to the longitudinally opposite side of the cylinder on the sleeve conveying frame. The shift rod extends longitudinally and is provided with a plurality of shift fork groups along its longitudinal extension direction.

DETAILED DESCRIPTION

[0021] In order to make the above features and advantages of the present invention more obvious and easy to understand, embodiments are given below with reference to the accompanying drawings for detailed description as follows.

[0022] like Figures 1 to 4 As shown, a sleeve conveying mechanism suitable for sleeves of different lengths comprises a sleeve conveying frame 1 which extends laterally and is slightly inclined, a pushing frame 2 is butted at the bottom of the sleeve conveying frame, a longitudinally extending slide rail 3 is provided in the pushing frame, a pushing block 4 is slidably connected in the slide rail, and a long push plate 5 is fixedly connected to the top of the driving block, a short push plate 6 is hingedly connected to the bottom of the pushing end of the long push plate, and the bottom of the short push plate away from the long push plate is connected to the upper end surface of the driving block via a spring 7, and receiving mechanisms 8 for receiving the sleeve are symmetrically arranged on both sides of the upper end of the pushing frame; a longitudinally extending cylinder 9 is fixedly provided near the bottom end of the sleeve conveying frame, and a positioning plate 10 is fixedly connected to the end of the cylinder to facilitate the adjustment of the sleeve.

[0023] In the embodiment of the utility model, the cross section of the slide rail is cross-shaped and the upper and lower ends both pass through the push rack, and the cross section of the push block is convex-shaped and the top end is at the same level as the upper end surface of the push rack.

[0024] In an embodiment of the utility model, the receiving mechanism includes a longitudinally extending U-shaped frame 11, and a plurality of support rollers 12 are evenly spaced along the longitudinal extension direction of the U-shaped frame. The support rollers are inclined toward the middle of the slide rail to be bidirectionally supported on the lower part of the sleeve, that is, the support rollers on both sides are opposite and inclined upward so that the end faces of the support rollers are supported on the lower side of the sleeve. The support rollers are rotatably connected to the U-shaped frame via a rotating shaft 13, and the bottom of the U-shaped frame is fixedly connected to the top of the pushing frame via a support seat 14.

[0025] In the embodiment of the utility model, a guide plate 15 extending obliquely inward is fixedly provided on one side of the sleeve conveying frame close to the short push plate, so as to guide the inclined sleeve so that the longer sleeve end can be pressed onto the short push plate.

[0026] In the embodiment of the utility model, the bottom of the cylinder is fixedly connected to a support plate 16, and the support plate is fixedly connected to the sleeve conveying frame. The sleeve conveying frame is provided with a notch 17 for the cylinder to be extended and retracted.

[0027] In the embodiment of the utility model, a shift rod 18 is rotatably connected to the longitudinally opposite side of the cylinder on the sleeve conveying frame. The shift rod extends longitudinally and is provided with a plurality of shift fork groups 19 along its longitudinal extension direction. Each shift fork group is composed of two shift forks 20 fixedly connected to the shift rod. The other end of the shift rod is driven to swing by a motor 21. Induction gratings are provided on the sleeve conveying frames on both sides of the shift rod to determine whether the sleeve is in place and to transmit the signal to the shift fork group, so as to avoid two groups of sleeves descending at the same time. The setting of the shift fork group effectively guides the tilted sleeve and ensures more orderly sleeve conveying.

[0028] In the embodiment of the utility model, a plurality of guide plates 22 are longitudinally spaced apart at the bottom of the sleeve conveying frame, and the tops of the guide plates are inclined downward to guide the sleeve onto the receiving mechanism for conveying transition.

[0029] In the embodiment of the utility model, a baffle 23 extending vertically to prevent the sleeve from falling off is fixedly provided on one side of the pushing rack away from the pushing rack.

[0030] In the embodiment of the utility model, the bottom of the pushing block is driven to move longitudinally via a longitudinally extending screw rod 24 .

[0031] The working principle of the embodiment of the utility model is as follows: first, the sleeve is transported to the fork on the sleeve conveying rack and is guided by the fork, and at this time the cylinder extends, and the sleeve is pushed longitudinally to be close to the other side of the sleeve conveying rack through the adjustment plate, and then the fork rod rotates, so that the sleeve is transported downward through the guide plate to the receiving mechanism of the pushing rack. If the sleeve is longer in length, the lower end thereof will fall on the short push plate under the guiding action of the guide plate, that is, the lower end of the sleeve will press it down, and the spring will be compressed. At this time, the screw rod will drive the pushing block to move longitudinally, and the sleeve will be pushed to the center position of the next station by the long push plate; if the sleeve is shorter in length, it will not be pressed on the short push plate if it is pushed longitudinally to the other end due to insufficient length, so the screw rod will drive the pushing block to move longitudinally, and the sleeve will be pushed to the center position of the next station by the short push plate, and no eccentricity will occur.

[0032] The utility model is not limited to the above-mentioned best implementation mode. Anyone can derive other various forms of sleeve conveying mechanisms suitable for sleeves of different lengths under the inspiration of the utility model. All equivalent changes and modifications made according to the scope of the patent application of the utility model shall fall within the scope of the utility model.
