Description

Technical Field

[0001] The invention relates to the technical field of plastic injection molding, and in particular to a finished product collecting and conveying device used for plastic workpiece injection molding. Background Art

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of the injection molding method are fast production speed, high efficiency, automated operation, a wide variety of colors, shapes from simple to complex, sizes from large to small, and precise product size. The product is easy to update and can be made into parts with complex shapes. Injection molding is suitable for mass production and molding processing fields such as products with complex shapes. At a certain temperature, the completely molten plastic material is stirred by a screw, injected into the mold cavity with high pressure, and cooled and solidified to obtain a molded product. This method is suitable for mass production of parts with complex shapes and is one of the important processing methods.

[0003] In the process of plastic injection molding, an injection molding machine is needed to perform related injection molding work. When the injection molding machine is used, a finished product collection and conveying device is needed to receive the workpieces produced by the injection molding machine and convey them to containers or other equipment.

[0004] Most of the related conveying devices in the prior art are general conveying equipment, such as conveyors with conveyor belts. In actual use, such devices can only convey molded plastic workpieces. However, after the injection molding machine performs injection molding on multiple small plastic workpieces, a small amount of plastic debris will be mixed in the multiple plastic workpieces during the unloading process. These debris will fall on the surface of the conveyor belt of the conveying device, and the staff will need to manually remove them later, which greatly reduces the efficiency of subsequent processing of the plastic workpieces and cannot meet people's usage needs. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to provide a finished product collection and conveying device for plastic workpiece injection molding.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0013] Optionally, a second slide groove is formed on the outer wall of the two guide rods away from the first slide block, a second slide block is installed inside the two second slide grooves, and a limit plate is installed together on one end of the two matching second slide blocks away from the second slide groove.

[0014] Optionally, the guiding mechanism includes two rotating plates rotatably installed on the top of the moving frame, grooves are provided on both side outer walls of the two rotating plates, telescopic airbags are installed inside the two grooves, electric push rods are rotatably installed on one side outer wall of the two rotating plates, and first rotating blocks are installed on the telescopic ends of the two electric push rods.

[0015] Optionally, the cleaning mechanism includes a third slide groove opened on the top of the vertical plate, two third sliders are installed inside the third slide groove, rotating rods are rotatably installed on the top of the two third sliders, and a movable plate is provided on the outer wall on the side where the two rotating rods are close to each other.

[0016] Optionally, two driving screws are installed at the bottom ends of the two rotating rods, and moving blocks are installed on the outer walls of the two driving screws. The two moving blocks are connected to the moving plates adjacent to them, and cleaning brushes and dust heads are installed at the bottom ends of the two moving plates.

[0017] The beneficial effects of the present invention are:

[0018] 1. In the present invention, by providing a moving frame and a driving mechanism, when a plurality of plastic workpieces fall into the moving frame for temporary storage, the driving mechanism drives the moving frame and the plurality of plastic workpieces to move back and forth on the top of the placement plate, and a small amount of plastic debris mixed in the plurality of plastic workpieces can be automatically removed, thereby facilitating the subsequent processing of the plastic workpieces and indirectly improving the processing efficiency of the plastic workpieces.

After the multiple small plastic workpieces are injection molded, as the injection mold moves, the multiple molded plastic workpieces fall downward together. With the help of the two rotated rotating plates and the telescopic airbags, the multiple fallen plastic workpieces can be guided and fall into the interior of the movable frame for temporary storage, ensuring that the multiple plastic workpieces can accurately enter the interior of the movable frame and wait for subsequent processing.

[0020] 3. In the invention, after a plurality of plastic workpieces are located on the top of the conveyor belt, the two driving screws arranged at the bottom of the two rotating rods are controlled to rotate synchronously, and the two movable plates are driven to move downward to a specified height together, and then the two third sliding blocks are controlled to move back and forth in the directions of approaching and moving away from each other inside the third slide groove, so as to flatten the stacked plurality of plastic workpieces, making it convenient for subsequent staff to perform trimming and other processing on the plastic workpieces.

[0021] 4. In the invention, while the two movable plates move back and forth, the external preset dust suction device is controlled to start, so that the two dust suction heads located at the bottom of the movable plates are started and generate suction. As the two third sliders drive the two movable plates to move back and forth, the two dust suction heads can synchronously remove dust and other fine impurities mixed in the multiple plastic workpieces. Finally, the conveyor belt is controlled to rotate to convey the multiple plastic workpieces in a direction away from the injection molding machine to the vicinity of other subsequent processing equipment, further facilitating the subsequent processing of the plastic workpieces.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Reference Figure 1-Figure 11 A finished product collecting and conveying device for plastic workpiece injection molding processing comprises a conveyor belt 2 and two brackets 1. The conveyor belt 2 is installed between the two brackets 1 through multiple driving shafts. A fixed plate 7 is installed on the outer wall of one side of one bracket 1 away from the conveyor belt 2, and a guide plate 9 is arranged above the fixed plate 7.

Two cleaning mechanisms for cleaning dust remaining on the surface of the plastic workpiece are installed on the top of the vertical plate 4.

[0037] As a technical optimization solution of the present invention, two electric telescopic rods 8 are installed on the top of the fixed plate 7, and the telescopic ends of the two electric telescopic rods 8 are jointly installed with a fixed seat 17, and the guide plate 9 is rotatably installed inside the fixed seat 17. In actual use, a first driving device is preset on the outer wall of one side of the fixed seat 17, and the output end of the first driving device is connected to the rotating part of the guide plate 9, so that the guide plate 9 can be driven to rotate and adjust inside the fixed seat 17.

[0039] As a technical optimization solution of the present invention, the driving mechanism includes a driving motor 18 installed at the bottom of the placement plate 10, and the output end of the driving motor 18 passes through the placement plate 10 and is installed with a rotating shaft 23, and the outer wall of the rotating shaft 23 is installed with two driving blocks 24. After starting, the driving motor 18 can drive the rotating shaft 23 and the two driving blocks 24 to rotate synchronously.

[0040] As a technical optimization solution of the present invention, two protrusions 21 are installed at one end of the placement plate 10 close to the driving motor 18, and the two protrusions 21 are connected to the moving frame 11 through two springs 22, and the two driving blocks 24 are in contact with the outer wall of the moving frame 11 close to the springs 22. Since the two driving blocks 24 are both elliptical, the two driving blocks 24 will continuously push the outer wall of one side of the moving frame 11 while rotating, and since the moving frame 11 and the two protrusions 21 are connected through the springs 22, the moving frame 11 can be reset after moving with the help of the elasticity of the springs 22, so as to achieve the effect that the two driving blocks 24 can continuously rotate and push the moving frame 11 to continuously move back and forth on the top of the placement plate 10.

[0041] As a technical optimization solution of the present invention, the limiting mechanism includes a first slide groove 27 opened on the inner wall of both sides of the moving frame 11, and two first sliders 28 are installed inside the two first slide grooves 27, and the ends of the two first sliders 28 away from the first slide grooves 27 are rotatably installed with guide rods 25. A first double-headed screw is preset inside the two first slide grooves 27, and one end of the two first double-headed screws is driven by a preset second driving device to drive the two first double-headed screws to rotate inside the corresponding first slide grooves 27. The two first sliders 28 are respectively matched with the outer walls of the corresponding first double-headed screws, so that the two first double-headed screws can drive the two corresponding first sliders 28 to move in the direction of approaching or moving away from each other after rotation; a third driving device is preset inside one of the first sliders 28, and the output end of the third driving device is connected to the rotating part of one of the guide rods 25, so that one of the guide rods 25 can be driven to rotate and adjust.

[0042] As a technical optimization solution of the present invention, the outer wall of the two guide rods 25 on the side away from the first slider 28 is provided with a second slide groove 29, and the second slider 30 is installed inside the two second slide grooves 29. The two second sliders 30 that match each other are installed with a limit plate 12 at one end away from the second slide groove 29. Linear motors are preset inside the two second slide grooves 29, and the two linear motors can drive the two second sliders 30 to move up and down inside the corresponding second slide grooves 29, and drive the limit plate 12 to move up and down between the two guide rods 25 for adjustment; Figure 1 As shown, the third driving device inside one of the first sliders 28 can drive one of the guide rods 25 close to the guide plate 9 to rotate and adjust, thereby driving one of the limit plates 12 close to the guide plate 9 and the other guide rod 25 to rotate together, so as to facilitate the downward discharge of the plastic workpieces collected inside the movable frame 11 into the inside of the guide plate 9.

[0043] As a technical optimization solution of the present invention, the guiding mechanism includes two rotating plates 13 rotatably installed on the top of the moving frame 11, grooves 32 are provided on the outer walls on both sides of the two rotating plates 13, telescopic air bags are installed inside the two grooves 32, electric push rods 31 are rotatably installed on the outer walls of one side of the two rotating plates 13, and the telescopic ends of the two electric push rods 31 are installed with first rotating blocks 26. Two first servo motors are preset at the top of the moving frame 11, and the output ends of the two first servo motors are respectively connected to the rotating parts of the two rotating plates 13, so as to drive the two rotating plates 13 to rotate and adjust; the telescopic airbags located inside the two grooves 32 can extend outward from the inside of the grooves 32 after being inflated, so that the two telescopic airbags in the extended state can cooperate with the rotating plates 13 after rotating upward to guide and limit the plastic workpieces falling downward, so that the plastic workpieces can accurately fall into the inside of the moving frame 11 for collection; and second servo motors are preset inside the two rotating plates 13, and the output ends of the two second servo motors are respectively connected to the two electric push rods 31, so as to drive the two electric push rods 31 and the first rotating block 26 to rotate.

[0044] As a technical optimization solution of the present invention, the cleaning mechanism includes a third slide 16 opened at the top of the vertical plate 4, and two third sliders 33 are installed inside the third slide 16. The tops of the two third sliders 33 are rotatably installed with rotating rods 5, and the outer walls of the two rotating rods 5 on the side close to each other are provided with moving plates 6. A second double-headed screw is preset inside the third slide 16, and one end of the second double-headed screw is connected to the output end of the preset third servo motor, so that the second double-headed screw can be driven to rotate inside the third slide 16. The two third sliders 33 are adapted to the outer wall of the second double-headed screw, so that the two third sliders 33 can be driven to move in the direction of approaching or moving away from each other by the rotation of the second double-headed screw; and a fourth servo motor is preset on the outer wall of one side of the two third sliders 33, and the output ends of the two fourth servo motors are respectively connected to the rotating parts of the two rotating rods 5, so that the two rotating rods 5 can be driven to rotate and adjust.

[0045] As a technical optimization scheme of the present invention, two driving screws 34 are installed at the bottom ends of the two rotating rods 5, and the outer walls of the two driving screws 34 are installed with moving blocks 36. The two moving blocks 36 are connected to the moving plates 6 close to them, and the bottom ends of the two moving plates 6 are installed with cleaning brushes 35 and dust heads 37. The outer walls of the two moving plates 6 close to each other are rotatably installed with second rotating blocks 15, and the side of the vertical plate 4 close to the two moving plates 6 is installed with a buffer pad 14. The top ends of the two rotating rods 5 are preset with fourth driving devices, and the output ends of the two fourth driving devices are respectively connected to the top ends of the two driving screws 34, so that the two driving screws 34 can be driven to rotate, and the two moving blocks 36 can be driven to move up and down on the corresponding driving screws 34 surfaces, and the moving plates 6 can be driven to move up and down synchronously; the two dust heads 37 are connected to the external preset dust suction equipment through hoses, so that after the external dust suction equipment is started, the two dust heads 37 generate suction to remove dust and other debris remaining on the surface of the plastic workpiece.

[0046] In the present invention, when the user uses the device, Figure 1 As shown, after placing the entire device near the front of the injection molding machine, control the telescopic ends of the two electric telescopic rods 8 to extend and retract together, driving the height of the upper guide plate 9 and the placement plate 10 to correspond to the position of the injection mold. As the pushing device moves toward the injection molding machine, drive the placement plate 10 to move to the bottom of the injection mold.

[0047] Before the injection molding machine performs injection molding of multiple smaller plastic workpieces, the two rotating plates 13 on the top of the movable frame 11 can be controlled to rotate upward together to form an inverted eight-shaped tilt state, and the telescopic airbags inside the grooves 32 on both sides of the two rotating plates 13 can be controlled to inflate and expand outward from the corresponding grooves 32, so that the two rotating plates 13 cooperate with the length of the two corresponding telescopic airbags in the expanded state to match the length of the movable frame 11. After multiple smaller plastic workpieces are injection molded, as the injection mold moves, multiple molded plastic workpieces fall downward together, and with the help of the two rotated rotating plates 13 and the telescopic airbags, the multiple fallen plastic workpieces can be guided and fall into the interior of the movable frame 11 for temporary storage, ensuring that the multiple plastic workpieces can accurately enter the interior of the movable frame 11 and wait for subsequent processing.

[0048] Since the injection molding machine performs injection molding on multiple plastic workpieces at the same time, a small amount of plastic debris will inevitably be mixed in the multiple plastic workpieces. After the multiple plastic workpieces enter the interior of the moving frame 11, according to the number of plastic workpieces in the moving frame 11, the two corresponding guide rods 25 can be controlled to drive the two limit plates 12 to move in a direction close to each other or away from each other, ensuring that the multiple plastic workpieces are located in a loose state inside the moving frame 11, and then the two rotating plates 13 above the moving frame 11 can be controlled to drive the deployed telescopic airbag to rotate in a direction close to the top of the moving frame 11, until the two rotating plates 13 and the telescopic airbag rotate to a state flush with the top of the moving frame 11, at which time the two rotating plates 13 and the telescopic airbag can block the top opening of the moving frame 11, and then the drive motor 18 is controlled to start and drive the rotating shaft 23 The two driving blocks 24 rotate with each other, so that the two driving blocks 24 can drive the moving frame 11 to move back and forth on the top of the placement plate 10 with the help of the elasticity of the multiple springs 22 during the continuous rotation, thereby driving the multiple plastic workpieces inside the moving frame 11 to move back and forth on the top of the placement plate 10, so that the plastic debris mixed in the plastic workpieces can fall downward through the multiple through grooves 19 into the preset collection container, thereby achieving the effect of automatically cleaning and removing the plastic debris mixed in the multiple injection-molded plastic workpieces. The two rotating plates 13 and the telescopic airbags located in a horizontal state on the top of the moving frame 11 can prevent the plastic workpieces inside the moving frame 11 from falling during the back and forth movement of the moving frame 11, thereby facilitating the subsequent plastic workpiece processing operations to be carried out quickly without spending time removing the plastic debris.

[0049] After removing the plastic debris mixed inside the plastic workpiece, the placement plate 10 can be controlled to rotate slightly upward to an inclined state, and ensure that the two driving blocks 24 push the moving frame 11 in the direction close to the guide plate 9, so that the gap between the moving frame 11 and the guide plate 9 is reduced to a minimum, and then control one group of guide rods 25 close to the guide plate 9 to rotate upward, driving one of the limit plates 12 to rotate upward and open in the direction close to the guide plate 9, so that the multiple plastic workpieces located inside the moving frame 11 can slide from the top of the placement plate 10 to the inside of the guide plate 9, and with the guidance of the guide plate 9, the multiple plastic workpieces are automatically guided to the top of the conveyor belt 2 for placement.

[0050] After the multiple plastic workpieces are located on the top of the conveyor belt 2, the two driving screws 34 arranged at the bottom of the two rotating rods 5 can be controlled to rotate synchronously, and the two movable plates 6 can be driven to move downward to a specified height together, and then the two third sliding blocks 33 can be controlled to move back and forth in the third sliding groove 16 in the direction of approaching and moving away from each other, so as to flatten the stacked multiple plastic workpieces, so as to facilitate the subsequent staff to perform trimming and other processing on the plastic workpieces;

[0051] At the same time, the external preset dust suction equipment can be controlled to start, so that the two dust suction heads 37 located at the bottom of the movable plate 6 start and generate suction. As the two third sliders 33 drive the two movable plates 6 to move back and forth, the two dust suction heads 37 can synchronously remove dust and other fine impurities mixed in the multiple plastic workpieces. Finally, the conveyor belt 2 is controlled to rotate to transport the multiple plastic workpieces in a direction away from the injection molding machine to the vicinity of other subsequent processing equipment, further facilitating the subsequent processing of the plastic workpieces.

[0052] And when the above-mentioned guide plate 9 transports multiple plastic workpieces to the top of the conveyor belt 2 for placement, the two movable plates 6 can be controlled to move in a direction close to each other until the spacing between the two movable plates 6 is matched with the width of the guide plate 9, so that the multiple plastic workpieces transported by the subsequent guide plate 9 can accurately fall on the position between the two movable plates 6, avoiding the accidental situation of the plastic workpieces falling from the top of the conveyor belt 2 during the process of falling on the top of the conveyor belt 2.

[0053] For example, multiple plastic workpieces that have been injection molded do not need to be transported by the conveyor belt 2, but only need to be collected together. In this case, there is no need to control the start of the conveyor belt 2, and the collection container such as the collection frame is placed between the two movable plates 6. The two movable plates 6 are controlled to move in a direction close to each other until the outer wall of one side of the two second rotating blocks 15 that are close to each other is tightly abutted against the outer walls of both sides of the collection container, thereby achieving the effect of limiting and clamping the collection container. The plastic workpieces that have been removed from the inside of the movable frame 11 can be adjusted in height by controlling the telescopic ends of the two electric telescopic rods 8 to extend upward, pushing the guide plate 9 and the placement plate 10 so that the lower end of the guide plate 9 is flush with the top of the collection container, and multiple plastic workpieces are discharged downward through the guide plate 9 After coming out, it can automatically fall into the collecting container until a sufficient amount of plastic workpieces are collected in the collecting container. By controlling the two rotating rods 5 to rotate 180 degrees in the direction close to the placing table 3, the clamped collecting container is driven to rotate together and placed on the top of the placing table 3. Since the two second rotating blocks 15 are rotatably connected with the corresponding moving plates 6, when the two rotating rods 5 drive the moving plates 6 to rotate, the collecting container will not rotate therewith, thereby preventing the plastic workpieces from falling out from the collecting container. The collecting container falling on the top of the placing table 3 can facilitate the staff to quickly carry it, and can also prevent the staff from working in an area close to the injection molding machine, which indirectly has a protective effect on the staff.

[0054] When the plastic workpiece is placed on the top of the placing plate 10, the two limiting plates 12 are controlled to clamp and fix the two sides of the plastic workpiece. Then, the two corresponding second slide blocks 30 are controlled to move upward inside the corresponding second slide grooves 29, and the two limiting plates 12 are driven to move upward together, and the clamped plastic workpiece is driven to move upward to the top of the moving frame 11. Then, the two rotating plates 13 are controlled to rotate upward to a vertical state, and the two first rotating blocks 26 are driven to extend together with the other two sides of the plastic workpiece after the upward movement, and the telescopic ends of the two electric push rods 31 are controlled to extend together, and the two first rotating blocks 26 are driven to move in a direction close to each other. After the other two sides of the plastic workpiece are clamped and fixed, the two limiting plates 12 are controlled to slide downward to a position lower than the plastic workpiece. The two first rotating blocks 26 drive the clamped plastic workpiece to flip together, so that the automatic appearance detection equipment can identify and detect the other side of the plastic workpiece. According to the combination of the two detection results of the plastic workpiece by the automatic appearance detection equipment, if there are defects on the surface of the plastic workpiece, the two first rotating blocks 26 can be controlled to drive the plastic workpiece to rotate into an inverted state, and then move upward with the help of the two limit plates 12, and clamp the two sides of the plastic workpiece. As the two limit plates 12 move downward and reset, the plastic workpiece in the inverted state is driven back to the top of the placement plate 10 for placement, so that when the subsequent guide plate 9 transports the plastic workpiece to the top of the conveyor belt 2 for placement, the defective plastic workpiece is located at the top of the conveyor belt 2 in an inverted state, and the qualified plastic workpiece is located at the top of the conveyor belt 2 in a normal state, thereby facilitating the subsequent staff to quickly identify and detect unqualified plastic workpieces, and classify and process them, thereby improving the efficiency of plastic workpiece processing.

[0055] After the device is used, a small amount of impurities such as plastic debris will inevitably adhere to the top of the conveyor belt 2. The two movable plates 6 can be controlled to move downward together until the cleaning brushes 35 arranged at the bottom of the two movable plates 6 abut against the surface of the conveyor belt 2. As the conveyor belt 2 rotates, the surface of the conveyor belt 2 continuously and automatically rubs against the cleaning brush 35, so that the plastic debris and other impurities on the surface of the conveyor belt 2 can be automatically cleaned with the help of the cleaning brush 35, which facilitates the subsequent use of the conveyor belt 2 and improves the applicability of the cleaning mechanism.
