Description

Technical Field

[0001] The utility model relates to the technical field of equipment for producing elevator parts, in particular to a sheet material unwinding rack for producing elevator parts. Background Art

[0002] An elevator is a permanent transportation device that serves several specific floors in a building. Its car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or have an inclination angle of less than 15° to the plumb line. There are also stepped types, with treads mounted on tracks and running continuously, commonly known as escalators or moving walkways. Elevators are roughly divided into two types, freight elevators and passenger elevators. It is customary to use elevators as a general term for vertical transportation vehicles in buildings, regardless of their driving mode.

[0003] An elevator is assembled with a variety of accessories. When producing elevator cars, an unwinding rack is needed to reel in and out sheet materials to facilitate stamping, cutting and forming of the sheet materials. The existing sheet unwinding rack for the production of elevator accessories generally supports the support shaft on one side, and the other end of the support shaft is in a suspended state, which is convenient for the sheet unwinding rack for the production of elevator accessories to load and unload sheets. Although this design is convenient for loading and unloading sheets, due to the heavy weight of the sheets, the other side of the support shaft has no support after long-term use, which will cause the support shaft to bend, causing the sheet unwinding rack for the production of elevator accessories to lose stability when reeling in and out the sheets, and unable to stably reel in and out the sheets, resulting in dimensional errors in the sheets during processing and producing defective products. To this end, we provide a sheet unwinding rack for the production of elevator accessories to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

A slide groove 9 is provided on the inner side of the support shaft 7. The outer surface of the support shaft 7 is slidably connected to the outer surface of the roller 5. When it is necessary to move up and down or replace the sheet material, the hydraulic cylinder 13 pushes the slide plate 2 to slide backward, and the slide plate 2 drives the support frame 3 and at the same time drives the roller 5 to break away from the contact with the support shaft 7, so that one end of the support shaft 7 produces a spatial position, and the support shaft 7 can be used to move the sheet material up and down by utilizing the generated spatial position. After the sheet material is moved up and down, the hydraulic cylinder 13 drives the slide plate 2 to slide, and the slide plate 2 drives the support frame 3 together with the roller 5 to move. After the movement, the roller 5 contacts the support shaft 7, and supports one end of the support shaft 7, so that both ends of the support shaft 7 are supported at the same time when it rotates, thereby increasing the stability of the support shaft 7 when rotating to retract and release the sheet material.

[0026] A control mechanism 10 is provided inside the support shaft 7, and the control mechanism 10 can control the fixing and releasing of the sheet material. The control mechanism 10 is wrapped around a threaded sleeve 1001, and the outer surface of the threaded sleeve 1001 is slidably connected to the inner wall of the support shaft 7. The inner wall of the threaded sleeve 1001 is threadedly connected with a lead screw 1002, and the outer surface of the lead screw 1002 is rotatably connected to the inner side of the support shaft 7. After the lead screw 1002 rotates, it can drive the threaded sleeve 1001 to move. The outer surface of the threaded sleeve 1001 is fixedly connected to a base 1003, and the outer surface of the base 1003 is slidably connected to the inner wall of the slide groove 9. When the threaded sleeve 1001 moves, it drives the base 1003 to move, and drives the first support arm 1103 to move and change its angle through the base 1003.

[0027] A locking mechanism 11 is provided on the outside of the support shaft 7, and the locking mechanism 11 can lock the sheet material to prevent the sheet material from loosening when it is retracted and released, which may cause the sheet material to slip during transportation and make it impossible to retract and release the sheet material.

When the base 1003 moves, it drives the first support arm 1103 to move its position and change its angle. After the first support arm 1103 moves its position and changes its angle, it pushes the tensioning plate 1101 to move upward and downward, and the tensioning plate 1101 moves After moving upward, it contacts the inside of the sheet material, supports and fixes the sheet material inside the sheet material, and can drive the sheet material to rotate when the support shaft 7 rotates, so as to retract and release the sheet material.

In order to prevent the tensioning plate 1101 from moving backward and being unable to move downward or upward, the tensioning plate 1101 is restrained by the second support arm 1105 so that the tensioning plate 1101 only has the function of moving upward and downward.

[0028] A power mechanism 8 is arranged below the door frame 6, and the power mechanism 8 can drive the support shaft 7 to rotate. The power mechanism 8 includes a motor 801, and the mounting seat of the motor 801 is fixedly connected to the upper surface of the base plate 1. The output shaft of the motor 801 is fixedly connected with a pulley 1 802. The motor 801 is used as a power source. After the motor 801 rotates, the pulley 1 802 is driven to rotate.

[0029] Working principle: When it is necessary to use a sheet material unwinding stand for the production of elevator accessories, the hydraulic cylinder 13 first pushes the slide plate 2 to slide backward. While the slide plate 2 slides backward, it drives the support frame 3 to move backward. At the same time, the support frame 3 drives the roller 5 to break away from the contact with the support shaft 7, so that a space position for the sheet material to be moved up and down is generated between the support frame 3 and the support shaft 7, and then the sheet material is installed on the support shaft 7. Subsequently, the hydraulic cylinder 13 drives the slide plate 2 to slide. The slide plate 2 drives the support frame 3 to move together with the roller 5. Subsequently, the roller 5 contacts the support shaft 7 to support the support shaft 7, so that both ends of the support shaft 7 are supported at the same time, so that the support shaft 7 has stability when rotating to retract and release the sheet material.
