Technical Field

[0001] This utility model relates to the field of pearl cotton processing technology, specifically to an automatic waste discharge device for pearl cotton die-cutting processing. Background Technology

[0002] Polyethylene foam, also known as EPE pearl cotton, is a non-crosslinked closed-cell structure and a new type of environmentally friendly packaging material. It is composed of countless independent air bubbles created through the physical foaming of low-density polyethylene resin. This overcomes the shortcomings of ordinary foam, such as fragility, deformation, and poor resilience. It possesses numerous advantages, including water and moisture resistance, shock absorption, sound insulation, heat insulation, excellent plasticity, high toughness, recyclability, environmental friendliness, and strong impact resistance. It also has excellent chemical resistance. After processing, the pearl cotton is a single unit. The inner frame needs to be punched according to the requirements of different packaging materials. After punching the entire pearl cotton unit, the blocky waste material in the inner frame needs to be removed.

[0003] In the prior art, there is a Chinese patent with authorization announcement number CN212656546U entitled "A Waste Discharge Device for Pearl Cotton". The patent discloses a waste discharge device for pearl cotton, including a frame, an ejection mechanism and two clamping mechanisms on the frame, and a fixed station between the two clamping mechanisms.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-7 This utility model provides a technical solution: an automatic waste discharge device for die-cutting pearl cotton, including a conveyor frame 1 and a fixed frame 2 installed on the conveyor frame 1. The fixed frame 2 is provided with a material distribution groove 3 adapted to pearl cotton, and a waste material unloading component is vertically slidably connected to the fixed frame 2. The fixed frame 2 is also provided with a servo cylinder 6 for driving the unloading component to slide vertically. The conveyor frame 1 is provided with a conveying component, and the unloading component and the conveying component are connected by intermittent linkage.

[0026] Specifically, this automatic waste removal device for EPE foam die-cutting includes a conveyor frame 1 and a fixed frame 2 mounted on the conveyor frame 1. The fixed frame 2 has a material distribution trough 3 adapted to the EPE foam. Therefore, when waste removal is needed, the EPE foam is placed in the material distribution trough 3 for convenient subsequent waste removal. A waste feeding component is vertically slidably connected to the fixed frame 2 to facilitate waste removal from the EPE foam inside the material distribution trough 3. The fixed frame 2 is equipped with a servo cylinder 6 to drive the vertical sliding of the feeding component, providing power for its vertical sliding. The conveyor frame 1 is equipped with a conveyor component, specifically used to transport waste material from the EPE foam. The feeding component and the conveyor component are connected by an intermittent linkage. Therefore, during use, the EPE foam is placed in the material distribution trough 3, and then the servo cylinder 6 drives the feeding component to slide downwards to complete the waste removal operation. When the feeding assembly moves downwards to remove waste from the pearl cotton, the conveyor will not operate to prevent waste from accumulating on it. After the feeding assembly completes the waste removal process, the servo cylinder 6 drives the feeding assembly to slide upwards. During the upward stroke of the feeding assembly, the conveyor will move, discharging the waste that has fallen on it. This prevents the discharged waste from accumulating at the bottom of the device and greatly improves the waste collection efficiency.

[0027] In the embodiments provided by this utility model, the feeding component includes a power plate 4 slidably connected to the fixed frame 2. Multiple sets of ejector pins 5 are fixedly connected to the bottom of the power plate 4, and the power plate 4 is installed at the output end of the servo cylinder 6. Therefore, in use, the power plate 4 is driven to slide downward by the servo cylinder 6, which in turn drives the multiple sets of ejector pins 5 to slide downward, thereby performing waste removal operation on the pearl cotton body.

[0028] In the embodiments provided by this utility model, the conveying component includes multiple sets of conveying rollers rotatably connected to the conveying frame 1, and a conveyor belt 7 is sleeved between the multiple sets of conveying rollers. A transmission rod 9 is provided on one of the conveying rollers, which drives the conveying roller to rotate, thereby realizing the rotation of the conveyor belt 7, so as to facilitate the conveying of waste materials to a predetermined position.

[0029] In the embodiments provided by this utility model, the intermittent linkage includes a drive rod 8 rotatably connected to the conveyor frame 1, and the drive rod 8 and the transmission rod 9 are connected by a synchronizing member 10; it also includes a drive gear 11, which is connected to the drive rod 8 by an intermittent connecting part; a rack 12 is fixedly connected to the power plate 4, and the rack 12 meshes with the drive gear 11; the intermittent connecting part includes a base 15 fixedly connected to the drive rod 8, a ratchet 14 is installed on the base 15, and a torque spring is provided between the ratchet 14 and the base 15; a toothed groove 13 is formed on the drive gear 11, and the elastic force of the torque spring drives the ratchet 14 to engage in the toothed groove 13. Specifically, the ratchet 14 is connected to the base 15 through a snap-fit ​​unit so that the ratchet 14 can only rotate clockwise. During operation, when the power plate 4 drives the ejector pin 5 to slide downwards, the rack 12 drives the drive gear 11 to rotate. At this time, the arc-shaped part of the tooth groove 13 on the drive gear 11 abuts against the arc-shaped part of the ratchet 14, preventing the ratchet 14 from rotating. When the power plate 4 drives the rack 12 to slide upwards, the rack 12 drives the drive gear 11 to rotate. At this time, the tooth groove 13 inside the drive gear 11 engages with the end of the ratchet 14, causing the ejector pin to rotate, which in turn drives the transmission rod 9 to rotate, thus realizing the movement of the conveyor belt 7. This facilitates the transport of waste materials to a predetermined position and prevents waste material from accumulating.

[0030] In the embodiments provided by this utility model, multiple sets of limiting members are provided between the power plate 4 and the fixed frame 2. The limiting members include a limiting block fixedly connected to the power plate 4. The fixed frame 2 is provided with a limiting groove adapted to the limiting block. The limiting block is vertically slidably connected in the limiting groove, which can improve the stability of the power plate 4 when sliding.

[0031] In the embodiments provided by this utility model, multiple sets of support members are provided on the bottom of the conveyor frame 1, which can improve the stability of the device during operation.

[0032] It should be noted that all electrical equipment involved in this application can be powered by batteries or external power sources.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
