Description

Technical Field

[0001] The invention relates to the technical field of injection molding production, in particular to an automatic water-cutting device. Background Art

[0002] Plastic products commonly used in daily life are usually injection molded using molds. During processing and molding, the gate on the product, also known as the sprue in the industry, will produce excess molding material. To ensure the integrity and good appearance of the product, the remaining sprue needs to be cut off after molding. At present, many ways to remove the product sprue still use pure manual sprue cutting jigs for processing, that is, after the product is injection molded, personnel are arranged to cut off the waste material handle next to the injection molding machine, which results in low efficiency of sprue cutting, so automatic equipment is also used for cutting.

[0003] In the prior art, the injection molding machine nozzle shearing mechanism with publication number CN206870300U discloses a manipulator, a product tooling, and a product shearing mechanism; the product tooling is installed at the free end of the manipulator, and the product shearing mechanism is located below the product tooling. The pneumatic scissors on the product shearing mechanism cut off the product material head, and the production process is automatically completed.

[0004] When the above scheme is implemented, when the product sprue is cut off, the pneumatic scissors will cut off the sprue one by one at a constant opening and closing speed and force. When the hardness of the sprue is relatively low, the sprue will not damage the blade of the pneumatic scissors. When the hardness of the sprue is relatively high, cutting the sprue with the same opening and closing speed and force will cause damage to the blade of the scissors, causing damage to the scissors and affecting the cutting quality of the product sprue. Summary of the invention

[0005] Based on this, it is necessary to provide an automated water nozzle cutting equipment to address the above technical problems, and adjust the position of the adjustment axis according to water nozzles of different hardness, so that when the water nozzle cutting equipment is shearing the water nozzle of the injection molded product, it can be adjusted in real time according to the hardness change of the water nozzle, and the cutting edge of the shear knife assembly can be protected to prevent damage during the shearing process, thereby improving the quality of the products produced.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: An automatic water cutting device, comprising: Frame; The shearing mechanism is installed on a frame, and the shearing mechanism includes a shearing seat installed with the frame, a plurality of shearing knife assemblies arranged on the shearing seat, and a driving member corresponding to the shearing knife assembly. Each of the shearing knife assemblies is installed with the shearing seat through a mounting seat. The shearing knife assembly includes two cross-arranged shearing arms, a positioning shaft installed at the intersection of the two shearing arms, a control shaft installed at an end away from the cutting edge of the shearing arm, and an adjusting shaft. The adjusting shaft is rotatably connected to the corresponding control shaft through two control rods. A driving gear ring is installed at the output end of the driving member, and the outer ring of the driving gear ring is meshed with a gear ring through teeth. A control disk is arranged in the middle of the gear ring, and an adjusting groove is opened in the radial direction of the control disk. The adjusting shaft is slidably connected along the adjusting groove, and a regulating mechanism for driving the adjusting shaft to slide along the adjusting groove is installed on the control disk.

The position of the product can be sensed by the photoelectric switch sensor, and when the water outlet of the product is placed at the shear knife assembly, the water outlet cutting process is started, and the cut product can fall through the recovery port to the recovery position at the bottom for collection, and the defective products can also be put into the recovery position at the bottom through the recovery port for easy recycling.

[0008] As a preferred embodiment of the automatic water cutting device provided by the present invention, the regulating mechanism includes an regulating block rotatably connected to the regulating shaft, an elastic bag embedded in the outer wall of the control disk, a toggle block installed on one side of the elastic bag, and a piston cylinder installed on the control disk. The toggle block is fixed to the inner wall of the gear ring, and the side of the regulating block close to the regulating shaft is plugged into the piston cylinder through a piston rod. The inner cavities of the elastic bag and the piston cylinder are connected in series through a pipeline. When the position of the regulating shaft is regulated, the regulating block is controlled to move up and down, thereby controlling the regulating shaft to move along the regulating groove. When the driving gear ring drives the gear ring to run, as shown in the figure, when the water outlet cut by the shearing arm has a harder texture, the shearing arm encounters resistance when biting, and the resistance is transmitted to the control disk through the control shaft, the control rod and the regulating shaft. At this time, the gear ring drives the toggle block to gradually squeeze the elastic bag, and the elastic bag is squeezed to the control disk. When the bag is squeezed, the pressure of the piston cylinder will increase synchronously through the pipeline. The increased pressure of the piston cylinder pushes the adjusting block to move through the piston rod, thereby synchronously controlling the adjusting axis to move toward the center of the control disk, so as to automatically adjust the position of the adjusting axis according to the hardness of the sprue, so that the shearing amplitude of the cutting edge of the shear arm is smaller, and the sprue with a harder texture is gradually sheared in small amplitude to protect the cutting edge of the shear arm to avoid its collapse, and when the sprue texture is soft, the toggle block reduces the squeezing of the elastic bag, the pressure in the elastic bag is reduced and cooperates with the elastic force of the supporting spring to control the adjusting block to move up and reset, thereby controlling the adjusting axis to move away from the center of the control disk, and realizing the function of automatically adjusting the shearing amplitude of the cutting edge of the shear arm according to the hardness of the sprue, so as to achieve the purpose of automatic adjustment when encountering different products and sprues with different hardness, protect the cutting edge of the shear knife assembly, and improve the quality of the products produced.

[0009] As a preferred embodiment of the automated water cutting equipment provided by the present invention, a support spring is installed on the side of the adjustment block away from the adjustment shaft, and a proximity switch and an electromagnet are installed at the inner cavity of the control disk and the corresponding parts of the adjustment block respectively. The adjustment block is made of ferromagnetic metal material, and the displacement of the adjustment block can be actively controlled by the electromagnet, and active regulation can be performed. The water cutting equipment also includes a shear intelligent controller installed on the frame.

[0010] As a preferred embodiment of the automatic water outlet cutting equipment provided by the present invention, it also includes a shearing intelligent controller installed on a frame, and the shearing intelligent controller is provided with a shearing module, an analysis module and a control module, the shearing module is respectively connected with the analysis module and the driving member signal, the analysis module is respectively connected with the control module, the proximity switch and the photoelectric switch sensor signal, the control module is connected with the electromagnet signal, when the water outlet of the product is sheared by the equipment, the photoelectric switch sensor senses the position signal of the product and sends it to the analysis module, the analysis module determines that the product moves to the shear knife assembly, the analysis module sends a shearing signal to the shearing module, the shearing module controls the driving member to work to shear the water outlet on the product, and when the shearing amplitude of the shearing arm needs to be actively adjusted, through The analysis module sends a main control signal to the control module, and the control module controls the operation of the electromagnet and the input current of the electromagnet to generate magnetic fields of different intensities, thereby controlling the displacement amplitude of the adjustment block and further adjusting the shear amplitude of the shear arm. When the hardness of the water outlet sheared by the shear arm is relatively large, the pressure in the elastic bag gradually increases and the adjustment block is pushed downward to contact the proximity switch. At this time, the proximity switch receives the position signal of the adjustment block and sends it to the analysis module. The analysis module determines that the hardness of the water outlet sheared by the corresponding shear arm is relatively large and will damage the cutting edge. The analysis module sends an alarm signal to the shearing module. After receiving the alarm signal, the shearing module controls the corresponding driving component to stop working, so that when the shearing arm encounters a product with a relatively large water outlet hardness, the shearing arm stops working in time to protect the cutting edge of the shearing arm.

[0011] As a preferred embodiment of the automatic water cutting equipment provided by the present invention, there are multiple elastic bags, and a toggle block is provided on one side of each elastic bag. The piston cylinder is arranged corresponding to the elastic bag, and the elastic bag is filled with hydraulic oil. By arranging multiple elastic bags and toggle blocks, the adjustment block can be pushed to move synchronously through multiple piston cylinders, which is convenient for precise control of the movement of the adjustment block.

[0012] As a preferred embodiment of the automatic water cutting equipment provided by the present invention, the positioning shaft is vertically slidably connected along the mounting seat, and a telescopic member whose output end is connected to the positioning shaft is installed on the mounting seat, so as to control the positioning shaft to move vertically along the mounting seat; a grinding plate corresponding to the cutting edge of the shear arm is provided on the mounting seat, and when the cutting edge of the shear arm is damaged, it is necessary to grind the cutting edge in time to ensure the sharpness of the cutting edge of the shear arm. At this time, the positioning shaft is driven to move by the telescopic member, thereby driving the shear arm to move, and controlling the cutting edge of the shear arm to move to the grinding plate, and the cutting edge of the shear arm is ground with the grinding plate by controlling the up and down displacement of the shear arm, thereby achieving the effect of grinding the cutting edge of the shear arm, and it is not easy for the worn shear arm to cause uneven water cutting of the product, thereby improving the quality of the produced products, and when the shear arm moves downward, it will synchronously drive the control disk and the gear ring to move downward and disengage from the driving gear ring, thereby avoiding continuous bite damage to the shear arm.

[0013] As a preferred embodiment of the automatic water outlet cutting equipment provided by the present invention, a grinding module is also provided on the shearing intelligent controller, and the grinding module is respectively connected with the analysis module and the telescopic part signal. In the process of shearing the product water outlet, when the analysis module receives the position signal sent by the proximity switch, it determines whether the number of times the signal of the corresponding proximity switch is received is within three times. When the result is yes, it is determined that the cutting edge of the corresponding shearing arm needs to be ground and repaired. At this time, the analysis module sends a repair signal to the grinding module, and the grinding module controls the telescopic part to work. The telescopic part controls the shearing arm to move downward through the positioning shaft so that its cutting edge moves to the grinding plate for grinding and repair, and the telescopic part resets after grinding for a predetermined time, and the shearing arm performs shearing again; when the result is no, it is determined that the cutting edge of the corresponding shearing arm is severely worn. At this time, the analysis module sends an alarm signal to the shearing module, and the shearing module controls the corresponding driving part to stop working after receiving the alarm signal.

[0015] As a preferred embodiment of the automatic water outlet cutting equipment provided by the present invention, an expansion top block is fixed to the lower end of the mounting seat, and the upper part of the expansion top block is a conical structure. The conical top of the expansion top block corresponds to the bottom gap of the two shear arms, so as to push open the lower ends of the two shear arms. When the shear arms are moved down for grinding and repair, in order to improve the repair effect, the shear arms are moved down to the bottom and contact with the expansion top block. As shown in the figure, the top of the expansion top block pushes open the bottom of the shear arm, so that the cutting edge of the top of the shear arm is ground with the grinding plate in an arc motion trajectory, thereby improving the grinding effect of the cutting edge of the shear arm and enabling it to better shear the water outlet.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides an automatic water nozzle cutting device. When shearing the water nozzle, the adjusting shaft can be controlled to be away from or close to the center of the control disk, so as to control the displacement amplitude of the adjusting shaft in the vertical direction. The driving member drives the driving gear ring to rotate, so as to drive the gear ring and the control disk to rotate synchronously, so as to control the upward and downward movement of the adjusting shaft. When the driving member runs at the same speed, when the controlling adjusting shaft is away from the center of the control disk, the upward and downward displacement amplitude is larger, so that the shearing amplitude of the cutting edge of the shearing arm is larger, and the water nozzle with a softer texture is sheared rapidly and significantly. When the controlling adjusting shaft is close to the center of the control disk, the upward and downward displacement amplitude is reduced, so that the shearing amplitude of the cutting edge of the shearing arm is smaller, and the water nozzle with a harder texture is sheared gradually and slightly. The position of the adjusting shaft is adjusted according to the water nozzles with different hardness by the regulating mechanism, so that when the water nozzle cutting device shears the water nozzle of the injection molded product, it can be adjusted in real time according to the hardness change of the water nozzle, and the cutting edge on the shear knife assembly is protected, so that it is not easy to be damaged during the shearing process, thereby improving the quality of the produced products.

It should be noted that the embodiments of the present invention and the features and technical schemes in the embodiments can be combined with each other without conflict.

[0022] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings. Embodiment 1

[0023] Please refer to Figure 1-Figure 6, an automatic water outlet cutting equipment, which includes a frame 1 and a shearing mechanism 3; the shearing mechanism 3 is installed on the frame 1, the shearing mechanism 3 includes a shearing seat 4 installed with the frame 1, a plurality of shearing knife assemblies 6 arranged on the shearing seat 4, and a driving member 7 corresponding to the shearing knife assembly 6, each shearing knife assembly 6 is installed with the shearing seat 4 through a mounting seat 8, the shearing knife assembly 6 is installed on the mounting seat 8, the water outlet of the product is sheared by the shearing knife assembly 6, the shearing knife assembly 6 includes two cross-arranged shearing arms 9, a positioning shaft 10 installed at the intersection of the two shearing arms 9, and a control shaft 11 installed at one end away from the cutting edge of the shearing arm 9. The control shaft 11 and the adjusting shaft 13 are rotatably connected with the corresponding control shaft 11 through two control rods 12. The two shear arms 9 are controlled to cross so that the cutting edges on the two shear arms 9 are matched, so that the nozzle located at the cutting edge is quickly sheared. The adjusting shaft 13 is periodically controlled to move up and down, so that the two control shafts 11 are controlled to move away from or close to each other through the two control rods 12, so as to control the cutting edge of the shear arm 9 to cut off the nozzle. A driving gear ring 15 is installed at the output end of the driving member 7. The outer ring of the driving gear ring 15 is meshed with a gear ring 14 through teeth. A control disk 16 is arranged in the middle of the gear ring 14. The control disk 16 is provided with an adjustment groove 21 along its radial direction, and the adjustment shaft 13 is slidably connected along the adjustment groove 21, so that the adjustment shaft 13 can be controlled to be away from or close to the center of the control disk 16, thereby controlling the displacement amplitude of the adjustment shaft 13 in the vertical direction. The driving gear ring 15 is driven to rotate by the driving member 7, thereby driving the gear ring 14 and the control disk 16 to rotate synchronously, thereby controlling the adjustment shaft 13 to move up and down. When the driving member 7 runs at the same speed, when the control adjustment shaft 13 is controlled to be away from the center of the control disk 16, its up and down displacement amplitude is large, so that the shearing amplitude of the cutting edge of the shearing arm 9 is large, and the water outlet with a soft texture can be sheared rapidly and significantly. When the control adjustment shaft 13 is close to the center of the control disk 16, the amplitude of its up and down displacement is reduced, so that the shearing amplitude of the cutting edge of the shear arm 9 is smaller. For the water outlet with a harder texture, a small amplitude is gradually sheared. A regulating mechanism for driving the regulating shaft 13 to slide along the regulating groove 21 is installed on the control disk 16. The position of the regulating shaft 13 is adjusted according to the water outlet with different hardness through the regulating mechanism. When the water outlet cutting equipment is shearing the water outlet of the injection molded product, it can be adjusted in real time according to the hardness change of the water outlet, and the cutting edge of the shear knife assembly 6 is protected, so that it is not easy to be damaged during the shearing process, thereby improving the quality of the produced products.

[0024] In addition, photoelectric switch sensors are installed on the shear seat 4 at the positions corresponding to the shear knife assembly 6, and recovery ports 5 are opened at the positions corresponding to the shear seat 4. A recovery position is provided at the position below the recovery port 5 of the frame 1. The position of the product can be sensed by the photoelectric switch sensor, and when the product water outlet is placed at the shear knife assembly 6, the water outlet cutting process is started. The cut product can fall through the recovery port 5 to the recovery position at the bottom for collection, and the defective products can also be put into the recovery position at the bottom through the recovery port 5 for easy recycling.

[0025] It is worth mentioning that Figure 5 and Figure 6 As shown, the regulating mechanism includes an regulating block 19 rotatably connected to the regulating shaft 13, an elastic capsule 18 embedded in the outer wall of the control disk 16, a toggle block 17 installed on one side of the elastic capsule 18, and a piston cylinder 20 installed on the control disk 16. The toggle block 17 is fixed to the inner wall of the gear ring 14. The side of the regulating block 19 close to the regulating shaft 13 is plugged into the piston cylinder 20 through a piston rod. The inner cavities of the elastic capsule 18 and the piston cylinder 20 are connected in series through a pipeline. When the position of the regulating shaft 13 is regulated, the regulating block 19 is controlled to move up and down, thereby controlling the regulating shaft 13 to move along the regulating groove 21. When the driving gear ring 15 drives the gear ring 14 to run, as shown in FIG. Figure 6 As shown, when the texture of the nozzle sheared by the shearing arm 9 is relatively hard, the shearing arm 9 encounters resistance when biting, and the resistance is transmitted to the control disk 16 through the control shaft 11, the control rod 12 and the adjusting shaft 13. At this time, the gear ring 14 drives the toggle block 17 to gradually squeeze the elastic bag 18. After the elastic bag 18 is squeezed, the pressure of the piston cylinder 20 is synchronously increased through the pipeline. The increased pressure of the piston cylinder 20 pushes the adjusting block 19 to move through the piston rod, thereby synchronously controlling the adjusting shaft 13 to move toward the center of the control disk 16, thereby automatically adjusting the position of the adjusting shaft 13 according to the hardness of the nozzle, so that the shearing amplitude of the cutting edge of the shearing arm 9 is smaller. , for the water outlet with harder texture, the cutting edge of the shear arm 9 is protected to avoid its collapse, and when the water outlet texture is soft, the toggle block 17 reduces the squeezing of the elastic bag 18, the pressure in the elastic bag 18 is reduced and cooperates with the elastic force of the supporting spring 24 to control the adjustment block 19 to move up and reset, thereby controlling the adjustment shaft 13 to move away from the center of the control disk 16, and realizing the function of automatically adjusting the shearing amplitude of the cutting edge of the shear arm 9 according to the hardness of the water outlet, so as to achieve the purpose of automatic adjustment when different products and water outlets with different hardness are encountered, protect the cutting edge of the shear knife assembly 6, and improve the quality of the products produced.

[0026] In addition, if Figure 6 and Figure 7As shown, a support spring 24 is installed on the side of the adjustment block 19 away from the adjustment shaft 13, and a proximity switch 22 and an electromagnet 23 are installed at the inner cavity of the control disk 16 corresponding to the adjustment block 19. The adjustment block 19 is made of ferromagnetic metal. The displacement of the adjustment block 19 can be actively controlled by the electromagnet 23, and active regulation can be performed. The water cutting device also includes a shearing intelligent controller 2 installed on the frame 1, and the shearing intelligent controller 2 is provided with a shearing module, an analysis module and a control module. The shearing module is respectively connected to the analysis module and the driving member 7 by signal, and the analysis module is respectively connected to the control module, the proximity switch 22 and the photoelectric switch sensor signal, and the control module is connected to the electromagnet 23 signal. When the water outlet of the product is sheared by the equipment, the photoelectric switch sensor senses the position signal of the product and sends it to the analysis module. The analysis module determines that the product moves to the shear knife assembly 6, and the analysis module sends a shearing signal to the shearing module. The shearing module controls the driving member 7 to work on the product. The water outlet on the product is sheared. When it is necessary to actively adjust the shearing amplitude of the shearing arm 9, a main control signal is sent to the control module through the analysis module. The control module controls the operation of the electromagnet 23 and controls the input current of the electromagnet 23 to generate magnetic fields of different strengths, thereby controlling the displacement amplitude of the adjustment block 19, and then adjusting the shearing amplitude of the shearing arm 9; when the hardness of the water outlet sheared by the shearing arm 9 is relatively large, the pressure in the elastic bag 18 gradually increases and the adjustment block 19 is pushed downward to contact the proximity switch 22. At this time, the proximity switch 22 receives the position signal of the adjustment block 19 and sends it to the analysis module. The analysis module determines that the hardness of the water outlet sheared by the corresponding shearing arm 9 is relatively large at this time, which will damage the cutting edge. The analysis module sends an alarm signal to the shearing module. After receiving the alarm signal, the shearing module controls the corresponding driving component 7 to stop working, so that when the shearing arm 9 encounters a product with a relatively large water outlet hardness, the shearing arm 9 is stopped in time to protect the cutting edge of the shearing arm 9.

[0027] In this embodiment, a plurality of elastic bags 18 are provided, and a toggle block 17 is provided on one side of each elastic bag 18. The piston cylinder 20 is provided corresponding to the elastic bag 18. The elastic bag 18 is filled with hydraulic oil. By providing a plurality of elastic bags 18 and toggle blocks 17, the adjustment block 19 can be pushed to move synchronously through the plurality of piston cylinders 20, so as to precisely control the movement of the adjustment block 19. Embodiment 2

[0028] The automatic water-cutting device provided in the first embodiment is further optimized. The difference from the first embodiment is that Figure 7-10As shown, the positioning shaft 10 is vertically slidably connected along the mounting seat 8, and a telescopic member 28 whose output end is connected to the positioning shaft 10 is installed on the mounting seat 8, so as to control the positioning shaft 10 to move vertically along the mounting seat 8. A sharpening plate 27 corresponding to the cutting edge of the shearing arm 9 is arranged on the mounting seat 8. When the cutting edge of the shearing arm 9 is damaged, it is necessary to grind the cutting edge in time to ensure the sharpness of the cutting edge of the shearing arm 9. At this time, the positioning shaft 10 is driven to move by the telescopic member 28, thereby driving the shearing arm 9 to move, and controlling the cutting edge of the shearing arm 9 to move to the sharpening plate 27. By controlling the up and down displacement of the shearing arm 9, the cutting edge is ground with the sharpening plate 27, so as to achieve the effect of grinding the cutting edge of the shearing arm 9, and it is not easy for the worn shearing arm 9 to cause uneven cutting of the product nozzle, thereby improving the quality of the produced products. When the shearing arm 9 moves downward, it will synchronously drive the control disk 16 and the gear ring 14 to move downward, and disengage from the driving gear ring 15, thereby avoiding the situation where the shearing arm 9 is continuously bitten and damaged.

[0029] It is worth mentioning that a grinding module is also provided on the shearing intelligent controller 2, and the grinding module is respectively connected with the analysis module and the telescopic part 28 signal. During the shearing process of the product water outlet, when the analysis module receives the position signal sent by the proximity switch 22, it determines whether the number of times the signal of the corresponding proximity switch 22 is received is within three times. When the result is yes, it is determined that the cutting edge of the corresponding shearing arm 9 needs to be ground and repaired. At this time, the analysis module sends a repair signal to the grinding module, and the grinding module controls the telescopic part 28 to work. The telescopic part 28 controls the shearing arm 9 to move downward through the positioning shaft 10 so that its cutting edge moves to the grinding plate 27 for grinding and repair, and the telescopic part 28 is reset after grinding for a predetermined time, and the shearing arm 9 performs shearing again; when the result is no, it is determined that the cutting edge of the corresponding shearing arm 9 is severely worn. At this time, the analysis module sends an alarm signal to the shearing module, and the shearing module will control the corresponding driving part 7 to stop working after receiving the alarm signal.

[0030] In this embodiment, if Figure 8 and Fig. 9 As shown, two positioning plates 25 parallel to the moving track of the positioning shaft 10 are fixed on the mounting seat 8, and the positioning plates 25 are placed on both sides of the gear ring 14 to limit the position of the gear ring 14, so that the gear ring 14 and the control plate 16 can be stably displaced with the shear arm 9. An expansion top block 26 is fixed to the lower end of the mounting seat 8, and the upper part of the expansion top block 26 is a conical structure. The conical top of the expansion top block 26 corresponds to the bottom gap of the two shear arms 9, so as to push the lower ends of the two shear arms 9 open. When the shear arms 9 are moved down for grinding and repair, in order to improve the repair effect, the shear arms 9 are moved down to the bottom and contact with the expansion top block 26, as shown in FIG. Fig. 9As shown, the top of the expansion top block 26 pushes open the bottom of the shear arm 9, so that the cutting edge of the top of the shear arm 9 is ground with the grinding plate 27 in an arc motion trajectory, thereby improving the grinding effect of the cutting edge of the shear arm 9 and enabling it to better shear the water outlet.
