DETAILED DESCRIPTION

[0022] The following will be combined with the attached embodiment of the present utility model Figure 1-3 , 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 them. Based on the embodiments of 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.

[0023] Example:

[0024] like Figures 1 to 3 As shown, the utility model discloses a bar material supporting device for a horizontal band sawing machine, comprising a sliding table 13 , a moving frame 11 slidably arranged on the sliding table 13 , and a material placing table 12 installed above the moving frame 11 .

[0025] In this structure, the sliding table 13 is used to fix the sliding direction of the moving frame 11 so that the material discharging table 12 can slide along a predetermined route. At the same time, the moving frame 11 is provided with a lifting mechanism for driving the material discharging table 12 to move up and down and a balancing mechanism for keeping the material discharging table 12 balanced, so that the material discharging table 12 can feed or receive materials for horizontal band saws with different table heights, specifically:

[0026] A slide groove 131 is provided on the upper end surface of the sliding table 13, and a wheel 111 for sliding in the slide groove 131 is provided on the mobile frame 11. Through this structure, the mobile frame 11 can move closer to or away from the horizontal band saw by sliding the wheel 111. In addition, a liftable positioning block 41 is provided between the mobile frame 11 and the sliding table 13. Specifically, a cylinder 42 is fixedly provided on the mobile frame 11, and the piston rod of the cylinder 42 is fixedly connected to the positioning block 41. Correspondingly, a plurality of positioning grooves 132 are arranged on the upper end surface of the sliding table 13 along the extension direction of the slide groove 131. The working principle of this structure is: when the mobile frame 11 moves to a suitable position with the unloading table 12, the cylinder 42 can drive the positioning block 41 to enter the positioning groove 132 to prevent the mobile frame 11 from sliding again.

[0027] The lifting mechanism includes a first hinge rod 21 and a second hinge rod 22 which are cross-arranged between the unloading platform 12 and the moving frame 11, and the first hinge rod 21 and the second hinge rod 22 are in a rotational connection relationship. The structural relationship between the first hinge rod 21 and the second hinge rod 22 and the unloading platform 12 and the moving frame 11 is as follows: a first hinge seat 23 and a second hinge seat 24 are slidably arranged on the side walls of the unloading platform 12 and the moving frame 11 which are opposite to each other, wherein the first hinge seat 23 is respectively used for rotational connection with the end portions of the first hinge rod 21, and the second hinge seat 24 is respectively used for rotational connection with the end portions of the second hinge rod 22. In addition, the lifting mechanism also includes a driving member, which is used to change the first hinge rod 21 and The crossing angle between the second hinged rod 22 enables the first hinged rod 21 and the second hinged rod 22 to drive the unloading platform 12 to rise and fall. The driving component specifically includes a motor 25 and a screw rod 26, wherein the motor 25 is fixedly arranged on the moving frame 11, and the screw rod 26 is rotatably arranged on the moving frame 11 and connected to the output end of the motor 25. At the same time, a limiting block 27 is fixedly connected to the second hinged seat 24 on the moving frame 11, and the limiting block 27 is sleeved outside the screw rod 26 and is threadedly connected to the screw rod 26.

[0028] At the same time, the balancing mechanism includes a telescopic rod 31, which is provided in plurality and is vertically arranged between the unloading platform 12 and the moving frame 11, and the upper and lower ends of the telescopic rod 31 are fixedly connected to the unloading platform 12 and the moving frame 11 respectively.

[0029] The working principle of the above structure is as follows: on the one hand, the telescopic rod 31 can keep the unloading platform 12 balanced at all times during the lifting process; on the other hand, the telescopic rod 31 can prevent the unloading platform 12 from being displaced relative to the moving frame 11 along the sliding direction of the moving frame 11 during the lifting process, which helps to ensure that the position of the unloading platform 12 can remain consistent with the moving frame 11 in the horizontal direction; at the same time, since the first hinge seat 23 and the second hinge seat 24 are both slidingly arranged, the telescopic rod 31 can also ensure the effective operation of the motor 25 and the screw rod 26, so that once the screw rod 26 rotates, the height of the unloading platform 12 must be adjusted.

[0030] like Figure 1 As shown, a material transport trough 121 is provided at the upper end of the unloading platform 12 , and a material transport roller 122 is rotatably provided in the material transport trough 121 . This structure is mainly used to facilitate the movement of the bar material on the unloading platform 12 .

[0031] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
