Description

Technical Field

[0001] This application relates to the field of PVC window and door processing technology, and more specifically, to a blanking mechanism for PVC window and door processing. Background Technology

[0002] PVC windows and doors typically consist of a square frame made of PVC structure, with glass glued inside the frame. During processing, holes need to be drilled in the PVC frame to facilitate subsequent installation.

[0003] Currently, when drilling, the plastic steel frame needs to be manually placed on a fixed table, and holes are drilled using a drill rod. After drilling, the plastic steel frame needs to be manually replaced. This requires manual replacement of the plastic steel frame at the machine, which is labor-intensive and inefficient.

[0004] In view of this, we propose a material cutting mechanism for processing PVC doors and windows. Utility Model Content

[0005] 1. Technical problems to be solved

[0006] The purpose of this application is to provide a material cutting mechanism for processing PVC doors and windows, which solves the technical problem in the background art where, during drilling, the PVC frame needs to be manually picked up and placed on a fixed table, and holes are drilled using a drill rod. After drilling, the PVC frame needs to be manually replaced. This requires manual replacement of the PVC frame at the machine, resulting in a large workload and low efficiency. This application achieves the desired technical effect.

[0007] 2. Technical Solution

[0008] This application provides a feeding mechanism for processing PVC-U doors and windows, comprising a frame, a conveyor belt installed on the inner wall of the frame, and a feeding cylinder for stacking PVC-U door and window frames fixedly installed at one end of the frame, and further comprising:

[0009] The drilling mechanism includes a fixed frame, an electric push rod, and a drill rod mounted on a frame, used to drill holes in the plastic steel door and window frame;

[0010] The drive mechanism, including a motor, drive shaft, and microswitches mounted on the outer wall of the frame, is used to drive the conveyor belt and control the electric push rod and drill rod.

[0011] The above method involves accumulating multiple PVC window and door frames inside the feeding cylinder. Then, the drive mechanism alternately drives the conveyor belt and the electric push rod, so that the PVC frames can be transported one by one to the bottom of the fixed frame when the conveyor belt is running. After the conveyor belt stops, the electric push rod extends to make the drill rod drill holes. After drilling, the conveyor belt runs again, automatically replacing the PVC frames, reducing manual labor, realizing automatic feeding, and improving processing efficiency.

[0012] Optionally, the bottom of the feeding cylinder and the top of the upper section of the conveyor belt form a discharge port, and a chute is inclinedly installed on the inner wall of the end of the frame away from the feeding cylinder.

[0013] Optionally, the inner length and width of the feed cylinder are equal to the length and width of the PVC window and door frame, and the outer wall of the conveyor belt is fixedly provided with a rubber layer, and the friction coefficient between the rubber layer and the PVC window and door frame is greater than the friction coefficient between two adjacent PVC window and door frames.

[0014] Optionally, the fixing frame is fixedly installed on the top of the frame, and an electric push rod is fixedly installed on the top of the fixing frame. The output rod of the electric push rod passes through the fixing frame and is fixedly connected to the slide plate. The two ends of the slide plate slide against the inner wall of the fixing frame. Motors are fixedly installed on the bottom of both sides of the slide plate. Drill rods are fixedly installed on the output shafts of the motors. Limiting plates are fixedly installed on both sides of the slide plate, and the bottom of the limiting plates has a sloping structure.

[0015] With the above scheme, the motor drives the drill rod to rotate, and the electric push rod drives the slide plate to move up and down. When the slide plate moves down, the limit plate is locked on both sides of the frame to limit it and prevent the frame from slipping. Thus, the drill rod can drill holes in the frame at the bottom of the fixed frame.

[0016] Optionally, a fixed base is fixedly installed on the outer wall of the frame, the motor is fixedly installed on the fixed base, the output shaft of the motor is fixedly sleeved with a drive wheel, a transmission shaft is rotatably sleeved on the outer wall of the frame on one side of the fixed base, the transmission shaft is connected to the rotating shaft of the conveyor belt through a transmission wheel and a transmission belt, a driven wheel is fixedly sleeved on the transmission shaft, the driven wheel has multiple stop grooves, a push groove is opened on the driven wheel between two adjacent stop grooves, a rotating groove is opened on the drive wheel, one end of a connecting rod is fixedly connected to the end face of the drive wheel at the rotating groove, a push rod is fixedly installed on the other end of the connecting rod, the push rod movably engages with the push groove, a micro switch is fixedly installed on the outer wall of the frame on the side of the fixed base away from the transmission shaft, the micro switch is electrically connected to an electric push rod and a motor, the stop grooves and push grooves are evenly distributed along the circumference of the driven wheel, and the rotating groove is an arc-shaped structure adapted to the outer circumference of the driven wheel.

[0017] With the above scheme, the motor drives the drive wheel to rotate continuously. When the trough turns towards the driven wheel, the push rod slides into the push groove to push the driven wheel to rotate. When the trough moves away from the driven wheel, the push rod slides out of the push groove, and at this time, the outer circumference of the drive wheel is engaged in the stop groove, causing the driven wheel to stop. Then, the transmission shaft intermittently drives the conveyor belt to rotate. When the driven wheel rotates, the push rod moves away from the micro switch, so the electric push rod and motor do not rotate. When the driven wheel stops, the push rod gradually rotates and contacts the micro switch, causing the electric push rod and motor to rotate. The electric push rod moves up and down once, causing the drill rod to drill a hole. Through the alternating operation of the conveyor belt and the electric push rod and motor, the plastic steel frame is fed into the bottom of the fixed frame one by one for drilling, eliminating the need for manual feeding and improving efficiency.

[0018] 3. Beneficial effects

[0019] One or more technical solutions provided in this application have at least the following technical effects or advantages:

[0020] 1. This application stacks multiple PVC window and door frames inside a feeding cylinder, and then drives the conveyor belt and electric push rod alternately through a drive mechanism. Thus, when the conveyor belt is running, the PVC frames can be transported one by one to the bottom of the fixed frame. After the conveyor belt stops, the electric push rod extends to make the drill rod drill holes. After drilling, the conveyor belt runs again to automatically replace the PVC frames, reducing manual labor, realizing automatic feeding, and improving processing efficiency.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] Reference Figure 1 This application provides a feeding mechanism for processing PVC-U doors and windows, comprising a frame 1, a conveyor belt 2 installed on the inner wall of the frame 1, and a feeding cylinder 3 for stacking PVC-U door and window frames fixedly installed at one end of the top of the frame 1. It also includes: a drilling mechanism 5, comprising a fixed frame 51, an electric push rod 52, and a drill rod 55 mounted on the frame 1, for drilling holes in the PVC-U door and window frames; and a drive mechanism 6, comprising a motor 61, a drive shaft 63, and a micro switch 610 mounted on the outer wall of the frame 1, for driving... The conveyor belt 2 and the electric push rod 52 and drill rod 55 are used to control the material feeding cylinder 3. Multiple plastic steel door and window frames are piled up. Then, the drive mechanism 6 alternately drives the conveyor belt 2 and the electric push rod 52, so that the plastic steel frames can be transported one by one to the bottom of the fixed frame 51 when the conveyor belt 2 is running. After the conveyor belt 2 stops, the electric push rod 52 extends to make the drill rod 55 drill holes. After drilling, the conveyor belt 2 runs again to automatically replace the plastic steel frames, reduce manual labor, realize automatic material feeding, and improve processing efficiency.

[0028] Reference Figure 1 The bottom of the feeding cylinder 3 and the top of the upper section of the conveyor belt 2 form a discharge port 31. A chute 4 is installed at an inclination on the inner wall of the end of the frame 1 away from the feeding cylinder 3. The height of the discharge port 31 is equal to the thickness of the plastic steel frame, so that one plastic steel frame is dropped at a time and transported by the conveyor belt 2, achieving the purpose of transporting the plastic steel frames one by one. The chute 4 facilitates the frame after drilling to slide to the ground.

[0029] Reference Figure 1 The inner length and width of the feed cylinder 3 are equal to the length and width of the plastic steel door and window frame. The outer wall of the conveyor belt 2 is fixed with a rubber layer, and the friction coefficient between the rubber layer and the plastic steel door and window frame is greater than the friction coefficient between two adjacent plastic steel door and window frames. Through the difference in friction coefficient, the conveyor belt 2 can carry the frame for transport.

[0030] Reference Figure 1 and Figure 3The fixed frame 51 is fixedly installed on the top of the frame 1. The electric push rod 52 is fixedly installed on the top of the fixed frame 51. The output rod of the electric push rod 52 passes through the fixed frame 51 and is fixedly connected to the slide plate 53. The two ends of the slide plate 53 slide against the inner wall of the fixed frame 51. Motors 54 are fixedly installed on the bottom of both sides of the slide plate 53. Drill rods 55 are fixedly installed on the output shafts of the motors 54. The motors 54 drive the drill rods 55 to rotate. The electric push rod 52 drives the slide plate 53 to move up and down. When the slide plate 53 moves down, the limiting plate 56 is engaged with both sides of the frame to limit the movement and prevent the frame from slipping. Thus, the drill rod 55 can drill holes in the frame at the bottom of the fixed frame 51.

[0031] Reference Figure 1 and Figure 2 A fixed base 611 is fixedly installed on the outer wall of the frame 1. The motor 61 is fixedly installed on the fixed base 611. The output shaft of the motor 61 is fixedly sleeved with a drive wheel 62. A transmission shaft 63 is rotatably sleeved on the outer wall of the frame 1 on one side of the fixed base 611. The transmission shaft 63 is connected to the rotating shaft of the conveyor belt 2 through a transmission wheel and a transmission belt. A driven wheel 64 is fixedly sleeved on the transmission shaft 63. Multiple stop grooves 65 are opened on the driven wheel 64. The driven wheel 64 between two adjacent stop grooves 65 is opened with... The drive wheel 62 has a push groove 66 and a rotating groove 67. One end of the connecting rod 68 is fixedly connected to the end face of the drive wheel 62 at the rotating groove 67. The other end of the connecting rod 68 is fixedly mounted with a push rod 69, which is movably engaged with the push groove 66. A micro switch 610 is fixedly mounted on the outer wall of the frame 1 on the side of the fixed base 611 away from the drive shaft 63. The micro switch 610 is electrically connected to the electric push rod 52 and the motor 54. The stop groove 65 and the push groove 66 are evenly distributed along the circumference of the driven wheel 64. The trough 67 is an arc-shaped structure adapted to the outer circumference of the driven wheel 64. The motor 61 drives the driving wheel 62 to rotate continuously. When the trough 67 turns towards the driven wheel 64, the push rod 69 slides into the push groove 66 to push the driven wheel 64 to rotate. When the trough 67 moves away from the driven wheel 64, the push rod 69 slides out of the push groove 66, and at this time, the outer circumference of the driving wheel 62 is engaged in the stop groove 65, causing the driven wheel 64 to stop. Then, the drive shaft 63 intermittently drives the conveyor belt 2 to rotate. Furthermore, when the driven wheel 64 rotates... When push rod 69 moves away from micro switch 610, electric push rod 52 and motor 54 do not operate. When driven wheel 64 stops, push rod 69 gradually rotates and contacts micro switch 610, causing electric push rod 52 and motor 54 to operate. Electric push rod 52 moves up and down once, causing drill rod 55 to drill. Through the alternating operation of conveyor belt 2 and electric push rod 52 and motor 54, the plastic steel frame is fed into the bottom of fixed frame 51 one by one for drilling, eliminating the need for manual feeding and improving efficiency.

[0032] Working principle: Multiple plastic steel door and window frames are piled up inside the feeding cylinder 3. The motor 61 drives the drive wheel 62 to rotate continuously. When the rotating groove 67 turns towards the driven wheel 64, the push rod 69 slides into the push groove 66 to push the driven wheel 64 to rotate. When the rotating groove 67 moves away from the driven wheel 64, the push rod 69 slides out of the push groove 66, and at this time, the outer circumference of the drive wheel 62 is engaged in the stop groove 65, causing the driven wheel 64 to stop. Then, the transmission shaft 63 intermittently drives the conveyor belt 2 to rotate. Furthermore, when the driven wheel 64 rotates, the push rod 69 pushes the driven wheel 64 to rotate. When rod 69 moves away from micro switch 610, electric push rod 52 and motor 54 do not operate. When driven wheel 64 stops, push rod 69 gradually rotates and contacts micro switch 610, causing electric push rod 52 and motor 54 to operate. Electric push rod 52 moves up and down once, causing drill rod 55 to drill. Through the alternating operation of conveyor belt 2 and electric push rod 52 and motor 54, the plastic steel frame is fed into the bottom of fixed frame 51 one by one for drilling, eliminating the need for manual feeding and improving efficiency.
