Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to a sorting device for an injection molding machine used in the production of injection molded parts. Background Art

[0002] Most of the accessories of the banknote counting machine are injection molded by an injection molding machine, such as the anti-copying plate of the banknote counting machine. During injection molding, a special injection mold is designed according to the structure of the anti-copying plate, and multiple anti-copying plates are formed by one injection molding. Since a runner is provided between adjacent anti-copying plate cavities, after the anti-copying plates are formed, there are connecting pieces connecting adjacent anti-copying plates, so it is necessary to punch and shear the connection position between the anti-copying plate and the connecting piece. After punching and shearing, the anti-copying plate body and the connecting piece waste are obtained, and it is necessary to sort the anti-copying plate body and the connecting piece waste.

[0003] The currently used sorting device conveys the mixed anti-copying plate bodies and connecting piece wastes to the sorting roller position through a conveyor belt. The anti-copying plate bodies fall from the gap between the conveyor belt and the sorting roller, and the connecting piece wastes are transmitted to the side far away from the conveyor belt through the sorting roller. However, during the sorting process, the anti-copying plate bodies and the connecting piece wastes will be in an overlapping state. When the anti-copying plate body is above the connecting piece waste, the connecting piece waste will support the anti-copying plate body, causing the anti-copying plate body to cross the gap between the conveyor belt and the sorting roller, and then being transmitted to the side far away from the conveyor belt through the sorting roller. Subsequently, manual sorting is required, resulting in poor sorting effect and low efficiency. Summary of the Invention

[0004] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by this patent application is how to provide a sorting device for an injection molding machine used in the production of injection molded parts that can improve the sorting effect and efficiency and is easy to use.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme:

The sorting component is located between the feeding conveyor belt and the discharging conveyor belt and is arranged at intervals from the feeding conveyor belt and the discharging conveyor belt. The upper end of the storage box is open. The feeding conveyor belt and the discharging conveyor belt are respectively installed on a feeding conveyor belt bracket and a discharging conveyor belt bracket. The feeding conveyor belt bracket and the discharging conveyor belt bracket are respectively arranged at both ends of the storage box and are fixedly connected to the storage box through support beams.

[0007] The sorting component includes a transmission structure and a vibration structure. The transmission structure includes three transmission rollers, and the vibration structure includes three vibration rollers. The transmission rollers and the vibration rollers are arranged alternately in sequence.

[0008] In this way, the mixed waste of the baffle body and the connecting piece is placed on the feeding conveyor belt. The feeding conveyor belt drives the baffle body and the waste of the connecting piece to move in the direction of the sorting component. The baffle body falls into the storage box through the gap between the feeding conveyor belt and the sorting component, while the waste of the connecting piece is conveyed to the discharging conveyor belt through the sorting component, realizing sorting. During the sorting process, the driving rollers are used for driving, and the driving rollers and the vibrating rollers are arranged alternately. Then the vibrating rollers can provide vibration to vibrate the overlapping baffle bodies and the waste of the connecting pieces, achieving the separation effect. After separation, the baffle body falls into the storage box through the gap between the sorting component and the discharging conveyor belt, improving the separation effect and separation efficiency.

[0009] Among them, the transmission structure includes two oppositely arranged support arms. Two support rods are fixedly installed at the upper end of the storage box.

The driving sprockets at the ends of adjacent driving rollers are connected by a driving chain. One of the driving rollers is fixedly connected to the output shaft of the driving motor, and the driving motor is fixedly installed on the support arm.

[0010] Among them, the vibration structure includes three brackets. The vibrating rollers are installed on the brackets through bearings. A vibrating sprocket is fixed at the end of the vibrating rollers on both sides, and two vibrating sprockets are fixed at the end of the vibrating roller in the middle. The vibrating sprockets at the ends of adjacent vibrating rollers are connected by a vibrating chain. One of the vibrating rollers is fixedly connected to the output shaft of the vibrating motor, and the vibrating motor is fixedly installed on the bracket;

[0011] The adjacent brackets are fixedly connected by a connecting arm. One of the support arms is fixed with a moving cylinder, and the cylinder rod of the moving cylinder is fixedly connected to the bracket in the middle through a connecting block.

[0012] Among them, a guiding block is fixedly installed downward on the connecting arm, and a guiding rod is fixed between the two support arms. The guiding block is slidably matched with the guiding rod.

[0013] Among them, a limiting plate is fixed at the upper end of the support arm.

[0015] In summary, the sorting device of the injection molding machine for producing injection molded parts of the present invention has the advantages of improving the sorting effect and sorting efficiency and being convenient to use. Description of the Drawings

[0016] Figure 1 It is a schematic structural diagram of a sorting device of an injection molding machine for producing injection molded parts of the present invention.

[0017] Figure 2 It is a schematic diagram of the sorting component.

[0018] Figure 3 It is Figure 2 A schematic diagram of another orientation after removing the support rod. Specific implementation manner

[0019] The following further describes the present utility model in detail with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by orientation words such as "upper, lower" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing the present utility model and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the protection scope of the present utility model; the orientation words "inside, outside" refer to the inside and outside relative to the contour of each component itself.

[0020] As Figures 1-3 shown, an injection molding machine sorting device for injection molding part production includes a storage box 1, a feeding conveyor belt 2, a discharging conveyor belt 3, and a sorting component 4. The sorting component is located between the feeding conveyor belt and the discharging conveyor belt and is spaced from the feeding conveyor belt and the discharging conveyor belt. The upper end of the storage box is open. The feeding conveyor belt and the discharging conveyor belt are respectively installed on the feeding conveyor belt support 5 and the discharging conveyor belt support 6. The feeding conveyor belt support and the discharging conveyor belt support are respectively arranged at both ends of the storage box and are fixedly connected to the storage box through a support beam 7;

[0021] The sorting component includes a transmission structure and a vibration structure. The transmission structure includes three transmission rollers 8, and the vibration structure includes three vibration rollers 9. The transmission rollers and the vibration rollers are arranged alternately in sequence.

[0022] In this way, the mixed baffle plate body 100 and the connecting piece waste 110 are placed on the feeding conveyor belt. The feeding conveyor belt drives the baffle plate body and the connecting piece waste to move towards the sorting component. The baffle plate body falls into the storage box through the gap between the feeding conveyor belt and the sorting component, and the connecting piece waste is conveyed to the discharging conveyor belt through the sorting component to achieve sorting. During the sorting process, the transmission rollers are used for transmission. The transmission rollers and the vibration rollers are arranged alternately, so the vibration rollers can provide vibration to vibrate the overlapped baffle plate body and the connecting piece waste to achieve separation. After separation, the baffle plate body falls into the storage box through the gap between the sorting component and the discharging conveyor belt, improving the separation effect and separation efficiency.

[0023] Specifically, the widths of the loading conveyor belt and the unloading conveyor belt are smaller than the length of the connecting piece waste, so as to prevent the connecting piece waste from falling down at intervals. The interval size is greater than half of the size of the baffle body, which enables the baffle body to fall easily. The interval size is smaller than half of the length size of the connecting piece waste, so as to prevent the connecting piece waste from falling from the interval.

[0024] During implementation, the transmission structure includes two oppositely arranged support arms 11. Two support rods 12 are fixedly installed at the upper end of the storage box. The support arms are fixedly installed on the support rods. The transmission roller is rotatably connected to the support arms through bearings. A transmission sprocket 13 is fixed at the end of the transmission rollers on both sides. Two transmission sprockets are fixed at the end of the transmission roller in the middle. The transmission sprockets 14 at the ends of adjacent two transmission rollers are connected by a transmission chain. One of the transmission rollers is fixedly connected to the output shaft of a transmission motor 15. The transmission motor is fixedly installed on the support arm.

[0025] In this way, the transmission motor drives the transmission roller to rotate. Through the transmission chain and the transmission sprocket, the transmission rollers are driven to rotate synchronously to achieve transmission.

[0026] During implementation, the vibration structure includes three brackets 21. The vibration rollers are installed on the brackets through bearings. A vibration sprocket 22 is fixed at the end of the vibration rollers on both sides. Two vibration sprockets are fixed at the end of the vibration roller in the middle. The vibration sprockets at the ends of adjacent two vibration rollers are connected by a vibration chain 23. One of the vibration rollers is fixedly connected to the output shaft of a vibration motor 24. The vibration motor is fixedly installed on the bracket;

[0027] The adjacent brackets are fixedly connected by a connecting arm 25. One of the support arms is fixed with a moving cylinder 26. The cylinder rod of the moving cylinder is fixedly connected to the bracket in the middle through a connecting block.

[0028] In this way, the vibration motor drives the vibration roller to rotate. Through the vibration chain and the vibration sprocket, the vibration rollers are driven to rotate synchronously, and the bracket is driven to move by the moving cylinder, so as to realize the rotation and movement of the vibration roller relative to the transmission roller, and further realize the effect of "lateral rubbing" relative to the transmission roller. When the baffle body and the connecting piece waste overlap, through the setting of the vibration structure, the overlapping baffle body and the connecting piece waste are quickly separated to achieve efficient sorting.

[0029] During implementation, a guide block 27 is fixedly installed downward on the connecting arm. A guide rod 28 is fixed between the two support arms. The guide block is slidably matched with the guide rod. Through the setting of the guide block and the guide rod, the bracket is supported and guided.

[0030] During implementation, a limiting plate 29 is fixed at the upper end of the support arm. It is convenient to limit the connecting piece waste so that it can reach the unloading conveyor belt better.

[0031] During implementation, one side of the storage box is open and is plugged and matched with a drawer 30. When the baffle body drops into the drawer, the drawer can be pulled out to take out the baffle body.

[0032] Finally, it should be noted that those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent statistical numbers, the present utility model also intends to include these modifications and variations.
