Profiles can be used alone or further processed into other manufactured products, and are often used in building structures and manufacturing and installation. Mechanical engineers can select the specific shape, material, heat treatment state, mechanical properties and other parameters of the profile according to the design requirements, and then divide the profile according to the specific size and shape requirements, and then further process or heat treat it to achieve the design accuracy requirements. The material, specifications and dimensions of the profile can refer to the corresponding national standards. In the process of dividing the profile, an automatic interruption saw is required. The automatic interruption saw is an automated equipment that can achieve the profile cutting effect.

[0003] The existing interruption saw needs to be used in conjunction with traction equipment, and an automatic feeding mechanism is used to improve processing efficiency. The conveying guide wheels of the existing feeding and conveying mechanisms are all fixedly installed, and the feeding cannot be adjusted according to the weight and thickness of the plate, which often leads to interference during the feeding process. In addition, the limit mechanism set on the feeding equipment cannot be adjusted as needed, and the convenience of use is poor. Utility Model Content

[0004] In view of the above problems, the utility model provides a simple saw feeding and conveying mechanism to solve the problems that interference is easy to occur during the feeding process and the limit mechanism cannot flexibly adjust the use state.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A simple saw feeding conveying mechanism comprises a conveying frame, wherein both sides of the upper end of the conveying frame along the length direction are fixedly provided with connecting guide rails for slidingly guiding the sawing mechanism, and a flip-adjustable side guard roller is installed on one side of the conveying frame, and the side guard roller is used to block and limit the feeding;

[0007] A plurality of counterweight conveying rollers for feeding and conveying workpieces are installed on the inner upper part of the conveying frame, and a guide bracket matching with the counterweight conveying rollers is fixedly installed on the side of the conveying frame away from the side guard roller.

[0010] As a further solution of the utility model: a driving convex plate is arranged in the middle of the driving frame, a connecting shaft is fixedly mounted on the driving convex plate, and a guide wheel is rotatably mounted on the connecting shaft.

[0011] As a further solution of the utility model: the side guard roller comprises a side guard shaft rotatably mounted on the conveyor frame, a side guard frame is fixedly arranged on the side guard shaft, and a plurality of side guard rollers are rotatably mounted on the side guard frame.

[0012] As a further solution of the utility model: a plurality of tension springs are connected to the side guard shaft, and the tension springs are fixedly connected to the conveyor frame.

Implementation

[0022] The technical solution of the utility model is described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figures 1 to 4 As shown, a simple saw feeding and conveying mechanism described in the utility model includes a conveying frame 1, and connecting guide rails 2 for slidingly guiding the sawing mechanism are fixedly arranged on both sides of the upper end of the conveying frame 1 along the length direction, and a flip-adjustable side guard roller 5 is installed on one side of the conveying frame 1, and the side guard roller 5 is used to block and limit the feeding; a plurality of counterweight conveying rollers 3 for feeding and conveying the workpiece are installed on the upper inner side of the conveying frame 1, and a guide bracket 4 matching the counterweight conveying roller 3 is fixedly installed on the side of the conveying frame 1 away from the side guard roller 5.

[0024] The guide bracket 4 is an inverted isosceles trapezoidal structure. When the workpiece moves to the guide bracket 4 under the action of the counterweight conveying roller 3, the counterweight conveying roller 3 moves downward under the guidance of the trapezoidal structure guide bracket 4, thereby driving the workpiece to move downward as a whole, thereby feeding the workpiece into the cutting saw to achieve cutting processing of the workpiece without interfering with the frame of the cutting saw, ensuring stable feeding and cutting.

[0025] The counterweight conveying roller 3 includes two groups of bearing seats 31 fixedly arranged on the conveying frame 1, a counterweight shaft 32 is installed between the two groups of bearing seats 31, a counterweight frame 33 is fixedly connected to the middle of the counterweight shaft 32, a roller support plate 34 is fixedly arranged at one end of the counterweight shaft 32, and a driving frame 37 is fixedly arranged at the other end of the counterweight shaft 32, a conveying shaft 35 is fixedly installed between the driving frame 37 and the roller support plate 34, and a conveying roller 36 is rotatably installed on the conveying shaft 35.

[0026] A driving convex plate is disposed in the middle of the driving frame 37 , a connecting shaft 38 is fixedly mounted on the driving convex plate, and a guide wheel 39 is rotatably mounted on the connecting shaft 38 .

[0027] The workpiece is conveyed by setting a counterweight conveying roller 3. Since a counterweight frame 33 is set on the counterweight shaft 32, when the weight of the conveyed workpiece is large, the conveying roller 36 is driven downward by the action of gravity, so that the upper surface of the workpiece can be kept at a relatively even height, thereby stably conveying the workpiece and no interference will occur when the workpiece is fed into the cutting mechanism.

[0028] The side guard roller 5 comprises a side guard shaft 51 rotatably mounted on the conveyor frame 1 , a side guard frame 53 is fixedly arranged on the side guard shaft 51 , and a plurality of side guard rollers 54 are rotatably mounted on the side guard frame 53 .

[0029] The side retaining shaft 51 is connected to a plurality of tension springs 52 , and the tension springs 52 are fixedly connected to the conveyor frame 1 .

[0030] A transmission plate 55 is fixedly connected to one end of the retaining shaft 51, a transmission shaft 56 is connected to the transmission plate 55, a transmission wheel 57 is rotatably mounted on the transmission shaft 54, a driving cylinder 59 is fixedly mounted on the conveyor frame 1, and a driving plate 58 meshingly connected to the transmission wheel 57 is fixedly connected to the output end of the driving cylinder 59.

[0031] Under normal conditions, the drive cylinder 59 is in an extended state, and the drive cylinder 59 drives the drive plate 58 to move upward. The drive plate 58 drives the baffle shaft 51 to rotate through the action of the transmission wheel 57 and the transmission plate 55, stretching the tension spring 52 so that the side guard frame 53 faces upward. At this time, the side guard roller 54 is in a vertical state with the upper surface of the conveyor frame 1, which plays a blocking and limiting role. When the traction machine passes through the side guard roller 5, the drive cylinder 59 resets downward, and the baffle shaft 51 rotates outward under the action of the tension spring 52, driving the side guard frame 53 and the side guard roller 54 to rotate outward, canceling their blocking and limiting functions.

[0032] Working principle: The guide bracket 4 of the inverted isosceles trapezoidal structure plays the role of downward limit guide for the counterweight conveying roller 3. The counterweight conveying roller 3 moves downward under the guidance of the trapezoidal structure guide bracket 4, thereby driving the workpiece to move downward as a whole, so as to feed the workpiece into the cutting saw to achieve cutting processing of the workpiece, and will not interfere with the frame of the cutting saw, ensuring stable feeding and cutting. The counterweight conveying roller 3 is set to convey the workpiece. Since a counterweight frame 33 is set on the counterweight shaft 32, when the weight of the conveyed workpiece is heavy, the counterweight conveying roller 3 is set to the counterweight frame 33. When the height of the workpiece is large, the conveying roller 36 is driven downward by gravity, so that the upper surface of the workpiece can be kept at a relatively even height, thereby stably conveying the workpiece. In the normal state, the side guard frame 53 faces upward, and the side guard roller 54 is vertical to the upper surface of the conveyor frame 1, which plays a blocking and limiting role. When the traction machine passes through the side guard roller 5, the drive cylinder 59 is reset downward, and the baffle shaft 51 rotates outward under the action of the tension spring 52, driving the side guard frame 53 and the side guard roller 54 to rotate outward, canceling their blocking and limiting functions.
