Description

Technical Field

[0001] The utility model belongs to the technical field of conveying devices, in particular to a plate feeding device of a sawing machine. Background Art

[0002] The raw materials of hydraulic valve blocks are usually cut from large metal plates. The length of such metal plates is usually 3 to 6 meters, and the width has specifications such as 20 cm, 30 cm, 40 cm, and 60 cm. During the sawing process, the metal plates are first processed along the length direction according to the width of the manufactured valve block, and the metal plates are sawn into multiple long strips, and then they are sawed into the required length of the valve block. In the process of sawing the plates into long strips, it is particularly important to adjust the conveying direction of the plates and the distance between the edge of the plates and the saw blade. Once there is a slight deviation in the conveying direction, the long strips finally sawed out will become wedge-shaped. If there is a large error in the distance between the edge of the plate and the saw blade, the raw materials will be scrapped or the processing allowance of the valve block will be large, increasing the processing cost. Therefore, the prior art provides limiting wheels on both sides of the conveying track of the sawing machine to limit the conveying direction of the plates and the distance between the edge of the plates and the saw blade. However, the existing technology mainly adjusts the position of the plate in the width direction of the track by hammering, checks the distance between the edge of the plate and the saw blade by measuring with a ruler, and checks the distance between multiple points in the length direction of the plate and the limit wheel by measuring with a ruler to ensure that the conveying direction of the plate is parallel to the edge of the plate after being limited by the limit wheel. The efficiency of the above adjustment and detection methods is relatively low, which seriously affects the production efficiency. Utility Model Content

[0003] In order to solve the deficiencies in the prior art, the utility model provides a plate feeding device for a sawing machine, which can effectively improve the positioning efficiency of the plate.

[0004] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0005] A plate feeding device for a sawing machine comprises: a feed track and a discharge track respectively arranged at two ends of the sawing machine processing direction, and limit wheels are arranged on both sides of the feed track, the limit wheels are perpendicular to the conveying plane, and the limit wheels are arranged to move along the width direction of the feed track and the discharge track. A mobile platform is arranged at the inlet end of the feed track, which is arranged to move along the feeding direction of the feed track, and a pair of push rods are arranged on the top surface of the mobile platform and the outlet end of the feed track, respectively, and the length direction of the push rods is consistent with the width direction of the feed track, and the push rods are threaded rod structures, and when the push rods are rotated, they move along the axis, and a mounting plate is arranged on the top surface of the mobile platform, which is perpendicular to the conveying surface of the feed track and the feeding direction, and at least two laser emitters are arranged on the mounting plate, and the direction of the laser beam is consistent with the feeding direction of the feed track, and the laser emitters are arranged along the width direction of the feed track, and the laser beam of one of the middle laser emitters intersects with the saw blade, and the remaining laser emitters are arranged to move along the width direction of the feed track.

[0006] The beneficial effects of the utility model are:

[0007] 1. This solution uses a threaded push rod to adjust the position of the plate in the width direction of the feed track, thereby avoiding the use of a hammer to hit it, making the adjustment process easier and more convenient.

[0013] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings, but the embodiments described in the utility model are only part of the embodiments of the utility model, rather than all the embodiments.

[0014] like Figure 1 , Figure 2As shown, a plate feeding device of a sawing machine includes: a feed track 1 and a discharge track 2 respectively arranged at both ends of the sawing machine in the processing direction, and limiting wheels 11 are arranged on both sides of the feed track 1. The limiting wheels 11 are perpendicular to the conveying plane, and the limiting wheels 11 are movably arranged along the width direction of the feed track 1 and the discharge track 2 to adapt to the distance between the edge of the plate and the saw blade, so as to obtain strip materials of different widths. A movable platform 3 is provided at the entrance end of the feed track 1, which is movable along the feeding direction of the feed track 1. A pair of push rods 4 are respectively provided on the top surface of the movable platform 3 and the exit end of the feed track 1. The length direction of the push rod 4 is consistent with the width direction of the feed track 1. The push rod 4 is a threaded rod structure. When the push rod 4 is rotated, it moves along the axis to adjust the position of the plate in the width direction of the feed track 1, so as to avoid hitting with a hammer, and the adjustment process is easier and more convenient. A mounting plate 31 is provided on the top surface of the movable platform 3, which is perpendicular to the conveying surface and feeding direction of the feed track 1. At least two laser emitters 32 are provided on the mounting plate 31. The direction of the laser beam is consistent with the feeding direction of the feed track 1, and the laser emitters 32 are arranged along the width direction of the feed track 1. The laser beam of one of the middle laser emitters 32 intersects with the saw blade, and the remaining laser emitters 32 are movable along the width direction of the feed track 1. When in use, adjust the movable laser emitter 32 so that the distance between it and the laser emitter 32 where the laser beam intersects the saw blade is equal to the width of the plate after it is sawed; rotate the top rod 4 and use it to adjust the position of the plate on the width of the feed track 1 so that the edge of the side of the plate that needs to be cut coincides with the beam emitted by the movable laser emitter 32, thereby ensuring that the distance between the edge and the saw mark of any section in the length direction of the plate is the same, thereby reducing the tedious process of multi-point detection, thereby improving the adjustment and detection efficiency of the plate; use the top rod 4 to adjust the position of the plate and then move the limit wheel 11 so that the limit wheel 11 contacts the two sides of the plate, and fix the limit wheel 11, thereby finally limiting the moving direction of the plate and the distance between the edge of the plate and the saw blade in the width direction of the feed track 1.

[0015] Preferably, Figure 2 As shown, a rotatably arranged round ball 41 is embedded in the front end of the push rod 4 so as to achieve rolling contact with the side surface of the plate during the plate conveying process to reduce friction.

[0016] Preferably, the distance between the mounting plate 31 and the top surface of the movable platform 3 is adjustable to accommodate different plate thicknesses, so that when the plate is placed, the beams from the laser emitter 32 can pass through the top surface of the plate, making it easier to observe the trajectory of each laser beam.

[0017] Preferably, Figure 2As shown, three laser emitters 32 are provided on the mounting plate 31, the rays of the middle laser emitter 32 intersect with the saw blade, and the laser emitters 32 on both sides are movable along the width direction of the feed track 1 to facilitate material cutting from both sides of the saw blade. More specifically, the mounting plate 31 is provided with a bar hole 311 for installing a laser emitter 32 with adjustable position.

[0018] The above is only a preferred embodiment of the utility model, and does not mean that it is the only one or limit the utility model. Those skilled in the art should understand that various changes or equivalent replacements made to the utility model without departing from the scope of the utility model are within the scope of protection of the utility model.
