[0002] The building materials processing industry continues to demand higher standards in production efficiency, product quality, and cost control. Traditional manual material feeding methods suffer from low efficiency, high labor intensity, and high labor costs. Furthermore, manual operation is susceptible to factors such as fatigue and skill level, leading to unstable feeding accuracy and consequently affecting product quality consistency. Therefore, an automatic feeding and conveying device for building materials processing centers is needed. Summary of the Invention

[0003] To address the problems in the background art, the present invention provides an automatic feeding and conveying device for a building material processing center. Its clamping component moves to the position of the building material rack and can automatically clamp the building material. It can also gradually push the building material upward through the pusher plate. When the clamping component moves to the position of the receiving trough rack, it can automatically unload the material, thereby realizing the automatic feeding and conveying of building material.

[0004] The present invention provides an automatic feeding and conveying device for a building material processing center, specifically comprising: a chain conveyor assembly, a clamping assembly, a building material rack, a receiving trough rack, a second stepper motor, and an electric push cylinder; The chain conveyor assembly consists of a first support frame, a first stepper motor, a drive shaft, a second support frame, a linkage shaft, a conveyor chain, and an annular groove frame; The clamping assembly includes a clamping fixing frame, a clamping plate, clamping claws, an L-shaped connecting rod, and a clamping spring; The clamping plate is provided in two sets. The two sets of clamping plates are located inside the clamping and fixing frame. The lower end of the inner side of the clamping plate is provided with two sets of clamping claws.

The bottom end of the building material rack is slidably fitted into the slot of the second support frame through a T-shaped plate structure, and the bottom end of the T-shaped plate structure is also equipped with support wheels. The front and rear sides of the building material rack are respectively provided with lifting grooves, and a pusher plate is slidably installed through the lifting grooves. The front and rear ends of the pusher plate are respectively threaded with threaded push shafts, and the bottom ends of the two sets of threaded push shafts are also connected by gear belt transmission.

When the rear end of the building material rack moves to the rear end of the second support frame slot, the bevel gear on the motor shaft of the second stepper motor meshes with the bevel gear on the rear threaded push shaft.

[0005] Furthermore, the first stepper motor and the drive shaft are respectively mounted on the first support frame, and the motor shaft of the first stepper motor and the drive shaft are connected by bevel gear transmission. The linkage shaft is mounted on the second support frame, and the conveyor chain is mounted between the upper side of the drive shaft and the linkage shaft through a sprocket. An annular groove frame is also provided on the upper side of the conveyor chain, and the inner end of the annular groove frame is fixedly connected to the first support frame and the second support frame respectively.

[0006] Furthermore, the clamping assembly also includes a connecting frame, which passes through the conveyor chain and extends downward through the slide groove on the clamping fixing frame. It is locked to the bottom end of the connecting frame on the upper and lower sides of the slide groove by nuts. Auxiliary wheels are also installed at the top two ends of the connecting frame, and the auxiliary wheels are placed in the annular groove frame.

[0007] Furthermore, the bottom ends of the clamping and fixing frame and the clamping plate are respectively higher than the top end of the building material frame and the top end of the right inclined section of the receiving trough frame.

[0008] Furthermore, the left and right ends of the bent plate are respectively connected to side support frames, and the left and right ends of the upper side of the building material rack are respectively provided with limiting groove frames A composed of two sets of L-shaped plates. The left and right ends of the upper side of the first bottom support frame are respectively provided with limiting groove frames B composed of two sets of L-shaped plates. The side support frames are slidably installed in the limiting groove frames A or B through the T-shaped plate ends on them.

[0009] Furthermore, the side support is also provided with a threaded hole, and an adjusting screw is engaged and inserted in the threaded hole. The front section of the adjusting screw is provided with a forward thread and engages with the threaded hole on the front side support, and the rear section is provided with a reverse thread and engages with the threaded hole on the rear side support.

[0010] Furthermore, the two sets of adjusting screws on the building material rack are respectively inserted into the outer connecting plate A fixed on the building material rack, and the rear ends of the two sets of adjusting screws are connected by a gear belt drive. The two sets of adjusting screws on the first base support frame are also respectively inserted into the outer connecting plate B fixed on the first base support frame, and the rear ends of the two sets of adjusting screws are also connected by a gear belt drive.

[0011] Furthermore, the outer ends of the L-shaped connecting rods are respectively connected to limiting plates, and when the outer ends of the two sets of L-shaped connecting rods pass through the straight section at point g of the bent plate, the L-shaped structure at the outer end of the L-shaped connecting rod does not contact the straight section at point g of the bent plate, and the limiting plate is attached to the clamping and fixing frame.

[0012] Furthermore, the right end of the straight section at point h on the front and rear sides of the building material rack is located to the right of the right side of the building material rack, the left end of the straight section at point h is directly opposite to the 1 / 4 point from the right to the left of the building material rack, and the right end of the straight section at point i of the bent plate is on the same vertical plane as the vertical middle of the lifting groove.

[0013] Furthermore, the left end of the straight section at point g of the bending plate on the front and rear sides of the receiving trough is level with the front and rear of the inclined section on the right side of the receiving trough.

[0014] The automatic feeding and conveying device for building material processing centers provided by this invention has the following beneficial effects: When the clamping component of this invention moves to the position of the building material rack, it can automatically clamp the building materials and gradually push the building materials upward through the pusher plate. When the clamping component moves to the position of the receiving trough rack, it can automatically unload the materials, thus realizing the automatic feeding and conveying of building materials.

[0015] Furthermore, by setting up a clamping assembly and a building material rack with a bending plate on it, the clamping assembly moves in a step-by-step manner under the drive of the chain conveyor assembly. When the clamping assembly moves to the right side of the building material rack, under the action of the limiting plate, the L-shaped connecting rod on the clamping assembly passes through the straight section at point g of the bending plate. During the movement from the straight section at point g to the straight section at point h, the L-shaped connecting rod pulls the clamping plate outward and into the outer side of the building material to be processed. During the movement from the straight section at point h to the straight section at point i, under the action of the clamping spring, the jaws insert into the inner side of the building material, and the clamping plate is tightly attached to the outer end of the building material, automatically clamping the building material and moving towards the receiving trough under the drive of the chain conveyor assembly.

[0016] In addition, by setting a second stepper motor and an electric pusher cylinder, the second stepper motor can drive two sets of threaded pusher shafts to rotate, and then push the building materials upward through the pusher plate, so that the building materials on the top side are pushed to the top and are aligned with the discharge gap on the building material rack. The electric pusher cylinder can also push the building material rack to move, so that when the building materials in the building material rack are short of materials, the building material rack can be pushed out to replenish the materials.

[0017] In addition, by setting up a receiving trough frame and a bending plate on it, when the clamping assembly moves to the receiving trough frame, under the action of the limiting plate, the L-shaped connecting rod on the clamping assembly passes through the straight section at point g of the bending plate. During the movement from the straight section at point g to the straight section at point h, the L-shaped connecting rod pulls the clamping plate to move outward. When it moves to the straight section at point h, the building material falls off from the inside of the two sets of clamping plates and slides down the inclined section on the receiving trough frame to the straight section, realizing the automatic feeding and conveying of building materials.

The upper left side of the building material rack 3 is also provided with a discharge notch 304. The receiving trough frame 5 consists of a right inclined section, a middle inclined section and a left straight section, and the bottom of the right inclined section is connected to a first bottom support frame 501 and the bottom of the left straight section is connected to a second bottom support frame 502. The front and rear ends of the building material rack 3 and the receiving trough rack 5 are respectively equipped with bent plates 4; The second stepper motor 6 and the electric push cylinder 7 are respectively fixed to the bottom end of the second support frame 104, and the telescopic front end of the electric push cylinder 7 is fixedly connected to the lower rear end of the building material rack 3. When the rear end of the building material rack 3 moves to the rear end of the slot of the second support frame 104, the bevel gear on the motor shaft of the second stepper motor 6 meshes with the bevel gear on the rear threaded push shaft 303.

[0024] The first stepper motor 102, the second stepper motor 6, and the electric pusher cylinder 7 are all electrically connected to an external control box (not shown in the figure), and can be controlled by the external control box.

[0025] In this embodiment of the invention, the first stepper motor 102 and the drive shaft 103 are respectively mounted on the first support frame 101, and the motor shaft of the first stepper motor 102 and the drive shaft 103 are connected by bevel gear transmission. The linkage shaft 105 is mounted on the second support frame 104. The conveyor chain 106 is mounted between the upper sides of the drive shaft 103 and the linkage shaft 105 through a sprocket. The upper side of the conveyor chain 106 is also provided with an annular groove frame 107, and the inner end of the annular groove frame 107 is fixedly connected to the first support frame 101 and the second support frame 104 respectively.

[0026] In embodiments of the present invention, such as Figure 8 As shown, the clamping assembly 2 also includes a connecting frame 205. The connecting frame 205 passes through the conveyor chain 106 and extends downward through the slide groove 2011 on the clamping fixing frame 201. The connecting frame 205 is locked to the bottom of the upper and lower sides of the slide groove 2011 by nuts. The top two ends of the connecting frame 205 are also equipped with auxiliary wheels 2051. The auxiliary wheels 2051 are placed in the annular groove frame 107 to facilitate the connection between the conveyor chain 106 and the clamping assembly 2 through the connecting frame 205.

[0027] In embodiments of the present invention, such as Figure 2 and Figure 3As shown, the bottom ends of the clamping and fixing frame 201 and the clamping plate 202 are respectively higher than the top end of the building material rack 3 and the top end of the right inclined section of the receiving trough frame 5. This is to enable automatic clamping and unloading of building materials via the clamping assembly 2.

[0028] In embodiments of the present invention, such as Figure 2 , Figure 6 and Figure 12 As shown, the left and right ends of the bent plate 4 are respectively connected to side support frames 401. The left and right ends of the upper side of the building material rack 3 are respectively provided with limiting slot frames A305 composed of two sets of L-shaped plates. The left and right ends of the upper side of the first bottom support frame 501 are respectively provided with limiting slot frames B5011 composed of two sets of L-shaped plates. The side support frame 401 is slidably installed in the limiting slot frame A305 or the limiting slot frame B5011 through the T-shaped plate end on it. The side support frame 401 is also provided with a threaded hole 4011, and an adjusting screw 402 is engaged and inserted in the threaded hole 4011. The front section of the adjusting screw 402 is provided with a positive thread, and it is respectively engaged with the front side support frame 401. The threaded hole 4011 on the upper part engages with the threaded hole 4011 on the rear section, and the reverse thread is provided on the rear section, which engages with the threaded hole 4011 on the rear side support 401 respectively. The two sets of adjusting screws 402 on the building material frame 3 are also inserted into the outer connecting plate A307 fixed on the building material frame 3 respectively, and the rear ends of the two sets of adjusting screws 402 are connected by gear belt drive. The two sets of adjusting screws 402 on the first bottom support 501 are also inserted into the outer connecting plate B5012 fixed on the first bottom support 501 respectively, and the rear ends of the two sets of adjusting screws 402 are also connected by gear belt drive. The front and rear position of the bending plate 4 as a whole can be adjusted by rotating the adjusting screws 402.

[0029] In embodiments of the present invention, such as Figure 2 and Figure 5As shown, the outer ends of the L-shaped connecting rods 203 are also connected to limiting plates 2031. When the outer ends of the two sets of L-shaped connecting rods 203 pass through the straight section at g of the bent plate 4, the L-shaped structure at the outer end of the L-shaped connecting rod 203 does not contact the straight section at g of the bent plate 4. The limiting plate 2031 is attached to the clamping and fixing frame 201. The right end of the straight section at h of the bent plate 4 on the front and rear sides of the building material rack 3 is located to the right of the right side of the building material rack 3. The left end of the straight section at h is directly opposite to the 1 / 4 point from the right side to the left side of the building material rack 3. The right end of the straight section at i of the bent plate 4 is perpendicular to the vertical middle of the lifting groove 301. On the same vertical plane, when the clamping assembly 2 moves to the right side of the building material rack 3, under the action of the limiting plate 2031, the L-shaped connecting rod 203 on the clamping assembly 2 passes through the straight section at g of the bending plate 4. During the movement from the straight section at g to the straight section at h, the L-shaped connecting rod 203 pulls the clamping plate 202 to move outward and enters the outside of the building material to be processed. During the movement from the straight section at h to the straight section at i, under the action of the clamping spring 204, the gripper 2021 inserts into the inside of the building material, and the clamping plate 202 is tightly attached to the outer end of the building material, automatically clamping the building material.

[0030] In embodiments of the present invention, such as Figure 3 and Figure 6 As shown, the left end of the straight section at g of the bending plate 4 on the front and rear sides of the receiving trough frame 5 is level with the right inclined section of the receiving trough frame 5. During the process of the clamping assembly 2 moving from the straight section at g of the bending plate 4 on the receiving trough frame 5 to the straight section at h, the clamping plate 202 is pulled outward by the L-shaped connecting rod 203. When it moves to the straight section at h, the building material falls off from the inside of the two sets of clamping plates 202, so that the building material can fall onto the right inclined section of the receiving trough frame 5.

[0031] The specific usage and function of this embodiment are as follows: In this invention, the push plate 302 is lowered to its lowest position through the transmission connection between the second stepper motor 6 and two sets of threaded push shafts 303. Then, the building material rack 3 is pushed out through the electric push cylinder 7, and the I-shaped building material processing materials are put into the building material rack 3 in sequence. The building material rack 3 is pulled back through the electric push cylinder 7, and the bevel gear on the threaded push shaft 303 on the rear side meshes with the bevel gear on the motor shaft of the second stepper motor 6. The first step motor 102 drives the conveyor chain 106 to move in a stepping motion. When the clamping assembly 2 moves to the right side of the building material rack 3, under the action of the limit plate 2031, the L-shaped connecting rod 203 on the clamping assembly 2 passes into the straight section at g of the bending plate 4. During the movement from the straight section at g to the straight section at h, the L-shaped connecting rod 203 pulls the clamping plate 202 to move outward and enters the outside of the building material to be processed. During the movement from the straight section at h to the straight section at i, under the action of the clamping spring 204, the gripper 2021 inserts into the inside of the building material. The clamping plate 202 is tightly attached to the outer end of the building material, automatically clamping the building material. Driven by the chain conveyor assembly 1, it moves towards the receiving trough rack 5 through the discharge notch 304. After the clamped building materials leave the building material rack 3, the second stepper motor 6 drives the two sets of threaded push shafts 303 to rotate, causing the pusher plate 302 to move upward, and then gradually push the building materials upward, so that the building materials on the top side of the building material rack 3 are pushed to the top and are opposite to the discharge notch 304 on the left side of the building material rack 3. When the clamping assembly 2 moves to the receiving trough frame 5, under the action of the limiting plate 2031, the L-shaped connecting rod 203 on the clamping assembly 2 passes through the straight section at g of the bending plate 4. During the movement from the straight section at g to the straight section at h, the L-shaped connecting rod 203 pulls the clamping plate 202 to move outward. When it moves to the straight section at h, the building material falls off from the inside of the two sets of clamping plates 202 and slides down the inclined section on the receiving trough frame 5 to the straight section, realizing the automatic feeding and conveying of the building material.
