Description
FIELD OF THE INVENTION The present invention relates to a processing device for long strip-shaped materials, in particular to an integrated feeding and cutting device for regular long strip-shaped materials. BACKGROUND OF THE INVENTION In a manufacturing workshop, it is often necessary to process long strip-shaped materials (such as round pipes) and transport them to different processing stations. Before the specific downstream manufacturing or assembly process, the long strip-shaped materials are generally fixed-length cut to obtain the desired shorter materials, and then the cut materials are further manufactured or assembled. Because the long strip-shaped materials (such as round pipes) are long, the pipes are generally placed during feeding one by one manually in a specific location on the mechanical equipment for processing, and the next pipe can be put in only after the last pipe is placed and processed, which will greatly waste manpower and material resources, result in high production costs, and make it difficult to obtain high production efficiency. CONTENTS OF THE INVENTION The purpose of the present invention is to overcome the above-mentioned problems by providing an integrated feeding and cutting device for regular long strip-shaped materials, which can achieve fully automatic feeding, transport, cutting, and discharging operations, reduce the labor intensity for workers, and effectively improve production efficiency. The purpose of the present invention is achieved through the following technical solution: An integrated feeding and cutting device for regular long strip-shaped materials is provided, comprising a feeding module for sending a stacked material, a middle transport module for transporting the material sent by the feeding module, a cutting module for cutting the material, and a discharging module for transporting the cut material downward; the feeding module, arranged at one side of a transport channel of the middle transport module, sends the material to the transport channel of the middle transport module perpendicularly to the transport direction of the middle transport module; and the middle transport module pushes the material to the cutting module in the direction in which the material extends; the feeding module comprises a material storage belt for storing the material and a feeding drive mechanism for driving to change the posture of the material storage belt, wherein one end of the material storage belt close to the middle transport module runs around a first support point and then is fixed on a frame, and the other end runs around a second support point and then is fixedly connected to the feeding drive mechanism; with the second support point higher than the first support point, the material is placed on a material storage portion of the material storage belt between the first support point and the second support point; the feeding drive mechanism comprises a feeding drive motor and at least two auxiliary transmission swing arms, wherein the bottom end of the auxiliary transmission swing arm is hinged to the frame, and the top end is fixedly connected to the material storage belt; and the feeding drive motor is connected with a hinge shaft at the bottom end of the auxiliary transmission swing arm through a rotating connection structure; and the middle transport module comprises a pushing mechanism and a transport channel; after passing the first support point, the material slides down onto the transport channel; and the pushing mechanism acts on one end of the material away from the cutting module, and pushes the material into the cutting module. The cutting module comprises a cutting machine and a clamping mechanism; the clamping mechanism comprises a fixed clamping mechanism to clamp the material for the cutting machine to stably cut the material, and a mobile clamping mechanism for fixed-length transporting the material to under a grinding wheel of the cutting machine, the fixed clamping mechanism being located in front of the mobile clamping mechanism in the direction in which the material is transported; and both the fixed clamping mechanism and the mobile clamping mechanism are provided with a clamping groove located on the same straight line as the transport channel; and a downwardly inclined middle feeding channel is arranged between the discharging module and the cutting module, the material falling into the middle feeding channel after being cut by the cutting machine; and the discharging module comprises a discharging channel, a discharging transport mechanism and a pushing mechanism, wherein the pushing mechanism and the discharging channel are respectively arranged at the two sides of the discharging transport mechanism, and the pushing mechanism pushes the material on the discharging transport mechanism to the next station in the direction perpendicular to the material. The working principle of the above-mentioned integrated feeding and cutting device is as follows: During the operation, first, a worker stores a material (the material with regular sides, such as a round pipe or a polygonal prism pipe) on the material storage belt, and then the feeding drive motor drives the auxiliary transmission swing arm away from the middle transport module, so that the auxiliary transmission swing arm swings outward around the hinge shaft, thereby pulling the material storage belt to extend outward beyond the second support point; as the material storage belt is stretched outward, the material storage portion is gradually lifted upward, so that the material stacked on the material storage belt also rises therewith; when the material rises above the first support point, the material will slide (roll) toward the middle transport module across the first support point until it reaches the transport channel in the middle transport module. Next, the pushing mechanism pushes against the end of the material away from the cutting module to move the material toward the cutting module, so that the front end of the material passes through the clamping grooves on the mobile clamping mechanism and the fixed clamping mechanism successively; and then the mobile clamping mechanism clamps the material and moves to the fixed clamping mechanism, so that the front end of the material continues to move relative to the clamping groove of the fixed clamping mechanism, until the length of the material extending out reaches a predetermined length. Then, the cutting machine drives the high-speed rotating grinding wheel to approach the material, so that the grinding wheel cuts the material; the cut and separated small pieces of material fall into the middle feeding channel, and then slide down from the downwardly inclined middle feeding channel to the discharging transport mechanism, which transports the separated pieces of material forward. After the material is transported to a specific position, the pushing mechanism pushes the material on the discharging transport mechanism in the direction perpendicular to the material, so that the material is transported to the next station through the discharging channel. After the previous section of the material is cut and separated, the mobile clamping mechanism continues to clamp and push forward the remaining section of the material to repeat the above cutting and discharging process. The above processes are repeated until all the material on the current round of material storage belt is processed. Furthermore, as the material on the material storage belt decreases, the material storage portion is gradually straightened from an arc into a straight line in shape; when all the material on the material storage belt is sent out, the material storage portion between the first support point and the second support point is stretched into a straight line, while the auxiliary transmission swing arm swings outward to the farthest point with its top end rotating to the lowest position to avoid the delivery mechanism, thereby reducing the height of delivery and greatly facilitating the delivery of the next round of materials to the material storage belt. Moreover, when the next round of material is placed on the material storage belt (at this time, the material storage belt is straightened or almost straightened), the gravity of the material acts directly on the material storage portion of the material storage belt, which causes the material storage portion to sag, so that the material storage belt is retracted inward, thereby exerting a reset force on the auxiliary transmission swing arm; in this way, the reset drive force of the feeding drive motor can be effectively reduced, with the feeding drive motor only needing to provide part of the drive force, which is beneficial to saving electric energy. In addition, when the feeding drive motor drives the auxiliary transmission swing arm to swing outward to lift the material, the auxiliary transmission swing arm rotates outward and downward from a vertical or nearly vertical state, with its own center of gravity gradually changed; this can convert the gravity of the auxiliary transmission swing arm into the drive force for driving the material storage belt, which can also reduce the power output of the feeding drive motor, thereby saving electric energy. Specifically, for materials of different types and sizes, by adjusting the gravity of the auxiliary transmission swing arm, it is possible to lift the materials or reset the auxiliary transmission swing arm without the help of an external force. In a preferred solution of the present invention, the second support point is the connection point between the auxiliary transmission swing arm and the material storage belt, and the first support point is the connection point between the frame and the material storage belt. In this way, both ends of the material storage belt are directly fixed between the frame and the top end of the auxiliary transmission swing arm, making the structure simple. In a preferred solution of the present invention, one end of the frame close to the auxiliary transmission swing arm is provided with at least two support columns disposed in the direction in which the auxiliary transmission swing arm is arranged, a support rod running through the upper end of the support columns; and the material storage belt is fixedly connected to the auxiliary transmission swing arm after passing over the support rod, with the portion where the support rod contacts the material storage belt constituting the second support point. By providing the support rod, the position of the second support point is fixed, thereby ensuring that the material storage belt can stably lift the material. Preferably, one support rod is provided, and runs through a plurality of support columns at the same time. In a preferred solution of the present invention, a plurality of single-row height-limiting mechanisms for restricting the passage of a single row of the material are arranged between the first support point and the transport channel; and the single-row height-limiting mechanism comprises an upper limit plate and a lower limit plate, between which a downwardly inclined height-limiting channel leading from the first support point to the transport channel is arranged. With the above structure, when the height of the material exceeds the first support point, the material will move orderly in a single row from the height-limiting channel to the transport channel, so as to be transported to the cutting module in turn through the transport channel.
Preferably, the height-limiting channel is provided at the end with a limit boss raised in the channel; and the limit boss is provided at one side with a lift mechanism, which comprises a lift member and a lift drive mechanism. During the operation, when the material passes through the height-limiting channel, it will be blocked in the limit channel by the limit boss, and then pushed out of the limit channel to reach the transport channel by the lift drive mechanism driving the lift member, so that the materials can be transported one by one, preventing multiple materials from entering the transport channel at the same time. Specifically, the lift drive mechanism is constituted by a lift drive cylinder, the lift member being vertically fixed on a retractable rod of the lift drive cylinder. In a preferred solution of the present invention, the middle transport module also includes at least two sets of support sliding mechanisms arranged in a V-shaped straight line, each of which comprises two pulleys rotatably arranged symmetrically in an inclined V-shaped structure, thereby forming the transport channel; when the pushing mechanism pushes the material, the pulley can slidably support the material, thereby greatly reducing the friction of the material in motion. In a preferred solution of the present invention, the pushing mechanism comprises a pushing arm and a pushing drive mechanism, wherein the pushing drive mechanism comprises a pushing drive motor and a pushing transmission assembly, and the pushing transmission assembly comprises a synchronous belt assembly and a screw-rod transmission assembly; the screw-rod transmission assembly comprises a screw rod and a screw-rod nut, wherein the screw rod, having both ends rotatably connected to the frame, is arranged in parallel at one side of the transport channel; and the pushing arm is fixedly connected to the screw-rod nut; and the synchronous belt assembly comprises a driving pulley arranged on the output shaft of the pushing drive motor, a driven pulley fixedly arranged at one end of the screw rod, and a synchronous belt surrounding the driving pulley and the driven pulley. Preferably, a lateral guide structure, comprising a guide rail and a slide block, is arranged between the screw-rod nut and the frame. In a preferred solution of the present invention, the mobile clamping mechanism comprises a mobile clamping assembly, and a lateral drive mechanism for driving the clamping assembly closer to or away from the fixed clamping mechanism; the mobile clamping assembly comprises a first mounting frame, a first clamping plate and a first clamping drive member, wherein the first mounting frame is provided on the top surface with a V-shaped clamping groove, and the first clamping drive member drives the first clamping plate closer to or away from the clamping groove. Preferably, the first clamping plate goes down through the first mounting frame via a first guide post, so as to be connected to the drive end of the first clamping drive member. Preferably, the lateral drive mechanism comprises a lateral drive motor, and a lateral transmission assembly that is a screw-rod transmission assembly, with the nut of the screw-rod transmission assembly fixedly connected to the mounting frame. In a preferred solution of the present invention, the fixed clamping mechanism includes a fixed clamping assembly, which comprises a second mounting frame, a second clamping plate and a second clamping drive member, wherein the second mounting frame is provided on the top surface with a V-shaped clamping groove, and the second clamping drive member drives the second clamping plate closer to or away from the clamping groove. Specifically, the first and second clamping drive members are both drive hydraulic cylinders, the first and second guiding posts being connected to the retractable rod of the drive hydraulic cylinders. Preferably, there are two sets of the fixed clamped assemblies, which are arranged in a straight line in front of the transport channel. In a preferred solution of the present invention, the discharging transport mechanism comprises a conveyor belt and a discharging drive motor, a baffle for blocking the cut material being arranged above the upper surface of the conveyor belt. In a preferred solution of the present invention, the pushing mechanism comprises a pushing plate and a pushing drive member, the pushing plate being connected to the drive end of the pushing drive member, the drive direction of the pushing drive member being perpendicular to the transport direction of the discharging transport mechanism. Specifically, the pushing drive member can be a drive cylinder, and the pushing plate can be fixed on the retractable rod of the drive cylinder. In a preferred solution of the present invention, the discharging channel is constituted by two inclined discharging plates, which can move relative to each other to change the width of the discharging channel. The present invention has the following beneficial effects compared with the prior art: 1. The integrated feeding and cutting device of the present invention can achieve fully automatic feeding, transport, cutting, and discharging operations, reduce the labor intensity for workers, and effectively improve production efficiency. 2. During feeding, when the feeding drive motor drives the auxiliary transmission swing arm to swing outward to lift the material, the auxiliary transmission swing arm rotates outward and downward from a vertical or nearly vertical state, with its own center of gravity gradually changed; this can convert the gravity of the auxiliary transmission swing arm into the drive force for driving the material storage belt, which can also reduce the power output of the feeding drive motor, thereby reducing the load on the feeding drive motor and saving electric energy. 3. When all the material on the material storage belt is sent out, the material storage portion between the first support point and the second support point is stretched into a straight line, while the auxiliary transmission swing arm swings outward to the farthest point with its top end rotating to the lowest position to avoid the delivery mechanism, thereby reducing the height of delivery and greatly facilitating the delivery of the next round of materials to the material storage belt. Moreover, when the next round of material is placed on the material storage belt (at this time, the material storage belt is straightened or almost straightened), the gravity of the material acts directly on the material storage portion of the material storage belt, which causes the material storage portion to sag, so that the material storage belt is retracted inward, thereby exerting a reset force on the auxiliary transmission swing arm; in this way, the reset drive force of the feeding drive motor can be effectively reduced, with the feeding drive motor only needing to provide part of the drive force, which is beneficial to saving electric energy. 4. For materials of different types and sizes, by adjusting the gravity of the auxiliary transmission swing arm, it is possible to lift the materials or reset the auxiliary transmission swing arm without the help of an external force.

As shown in Figs. 1-6, the feeding module comprises a material storage belt 1 for storing the material a and a feeding drive mechanism for driving to change the posture of the material storage belt 1, wherein one end of the material storage belt 1 close to the middle transport module runs around a first support point b and then is fixed on a frame 2, and the other end runs around a second support point c and then is fixedly connected to the feeding drive mechanism; with the second support point c higher than the first support point b, the material a is placed on a material storage portion of the material storage belt 1 between the first support point b and the second support point c; the feeding drive mechanism comprises a feeding drive motor 3 and at least two auxiliary transmission swing arms 4 (in this example, there are three auxiliary transmission swing arms 4 and, of course, there may be two, four or even more), wherein the bottom end of the auxiliary transmission swing arm 4 is hinged to the frame 2, and the top end is fixedly connected to the material storage belt 1; and the feeding drive motor 3 is connected with a hinge shaft at the bottom end of the auxiliary transmission swing arm 4 through a rotating connection structure, which may be a synchronous gear structure or a synchronous belt structure. As shown in Figs. 1-6, the middle transport module comprises a pushing mechanism and a transport channel; after passing the first support point b, the material a slides down onto the transport channel; and the pushing mechanism acts on one end of the material a away from the cutting module, and pushes the material a into the cutting module. As shown in Figs. 1-6, the cutting module comprises a cutting machine 5 and a clamping mechanism; the clamping mechanism comprises a fixed clamping mechanism 7 to clamp the material a for the cutting machine 5 to stably cut the material a, and a mobile clamping mechanism 6 for fixed-length transporting the material a to under a grinding wheel of the cutting machine 5, the fixed clamping mechanism 7 being located in front of the mobile clamping mechanism 6 in the direction in which the material a is transported; and both the fixed clamping mechanism 7 and the mobile clamping mechanism 6 are provided with a clamping groove located on the same straight line as the transport channel.

As shown in Fig. 12, in a preferred solution of the present invention, the discharging transport mechanism comprises a conveyor belt 23 and a discharging drive motor 24, a baffle 25 for blocking the cut material being arranged above the upper surface of the conveyor belt 23.
As shown in Fig. 12, the pushing mechanism comprises a pushing plate 26 and a pushing drive member 27, the pushing plate 26 being connected to the drive end of the pushing drive member 27, the drive direction of the pushing drive member 27 being perpendicular to the transport direction of the discharging transport mechanism. Specifically, the pushing drive member 27 can be a drive cylinder, and the pushing plate 26 can be fixed on the retractable rod of the drive cylinder. Furthermore, the discharging channel 9 is constituted by two inclined discharging plates 28, which can move relative to each other to change the width of the discharging channel 9. As shown in Figs. 1-12, the working principle of the above-mentioned integrated feeding and cutting device is as follows: During the operation, first, a worker stores the material a (such as a round pipe) on the material storage belt 1, and then the feeding drive motor 3 drives the auxiliary transmission swing arm 4 away from the middle transport module, so that the auxiliary transmission swing arm 4 swings outward around the hinge shaft, thereby pulling the material storage belt 1 to extend outward beyond the second support point c; as the material storage belt 1 is stretched outward, the material storage portion is gradually lifted upward, so that the material a stacked on the material storage belt 1 also rises therewith, as shown in Figs. 4-5; when the material a rises above the first support point b, the material a will slide (roll) toward the middle transport module across the first support point b until it reaches the transport channel in the middle transport module, as shown in Fig. 6. Next, the pushing mechanism pushes against the end of the material a away from the cutting module to move the material a toward the cutting module, so that the front end of the material a passes through the clamping grooves on the mobile clamping mechanism 6 and the fixed clamping mechanism 7 successively; and then the mobile clamping mechanism 6 clamps the material a and moves to the fixed clamping mechanism 7, so that the front end of the material a continues to move relative to the clamping groove of the fixed clamping mechanism 7, until the length of the material a extending out reaches a predetermined length, as shown in Figs. 9-11. Then, the cutting machine 5 drives the high-speed rotating grinding wheel to approach the material a, so that the grinding wheel cuts the material a; the cut and separated small pieces of material a fall into the middle feeding channel 8, and then slide down from the downwardly inclined middle feeding channel 8 to the discharging transport mechanism, which transports the separated pieces of material a forward. After the material is transported to a specific position, the pushing mechanism pushes the material a on the discharging transport mechanism in the direction perpendicular to the material a, so that the material a is transported to the next station through the discharging channel 9. After the previous section of the material a is cut and separated, the mobile clamping mechanism 6 continues to clamp and push forward the remaining section of the material a to repeat the above cutting and discharging process. The above processes are repeated until all the material a on the current round of material storage belt 1 is processed. Furthermore, as the material a on the material storage belt 1 decreases, the material storage portion is gradually straightened from an arc into a straight line in shape; when all the material a on the material storage belt 1 is sent out, the material storage portion between the first support point b and the second support point c is stretched into a straight line, while the auxiliary transmission swing arm 4 swings outward to the farthest point with its top end rotating to the lowest position to avoid the delivery mechanism, thereby reducing the height of delivery and greatly facilitating the delivery of the next round of material a to the material storage belt 1. Moreover, when the next round of material a is placed on the material storage belt 1 (at this time, the material storage belt 1 is straightened or almost straightened), the gravity of the material a acts directly on the material storage portion of the material storage belt 1, which causes the material storage portion to sag, so that the material storage belt 1 is retracted inward, thereby exerting a reset force on the auxiliary transmission swing arm 4; in this way, the reset drive force of the feeding drive motor 3 can be effectively reduced, with the feeding drive motor 3 only needing to provide part of the drive force, which is beneficial to saving electric energy. In addition, when the feeding drive motor 3 drives the auxiliary transmission swing arm 4 to swing outward to lift the material a, the auxiliary transmission swing arm 4 rotates outward and downward from a vertical or nearly vertical state, with its own center of gravity gradually changed; this can convert the gravity of the auxiliary transmission swing arm 4 into the drive force for driving the material storage belt 1, which can also reduce the power output of the feeding drive motor 3, thereby saving electric energy. Specifically, for materials a of different types and sizes, by adjusting the gravity of the auxiliary transmission swing arm 4, it is possible to lift the materials a or reset the auxiliary transmission swing arm 4 without the help of an external force. Example 2 This example, as shown in Fig. 13, is different from Example 1 in that the second support point c is the connection point between the auxiliary transmission swing arm 4 and the material storage belt 1, and the first support point b is the connection point between the frame 2 and the material storage belt 1. In this way, both ends of the material storage belt 1 are directly fixed between the frame 2 and the top end of the auxiliary transmission swing arm 4, making the structure simple.
Example 3 This example is different from Example 1 in that there are a plurality of support rods 11 (in this example, there are three discrete support rods 11), the number of which being the same as that of the support columns 10. The above-mentioned examples are preferred embodiments of the present invention; however, the embodiments of the present invention are not limited to these examples, and any other alterations, modifications, replacements, combinations and simplifications that are made without departing from the spirit and principle of the present invention shall be equivalent substitutions and within the protection scope of the present invention.
