Description

Technical Field

[0001] This utility model belongs to the technical field of automated stamping production equipment, and specifically relates to a reciprocating feeding and waste discharge device. Background Technology

[0002] In modern industrial production sectors such as machining, stamping, and injection molding, a large amount of waste is generated during the production process. Traditional waste disposal methods largely rely on manual operation, requiring workers to regularly clean and remove waste generated by production equipment. This manual waste removal method has many drawbacks and increases labor costs.

[0003] In addition, most of the existing semi-automatic waste discharge equipment has a complex structure and a high failure rate. Moreover, the speed and efficiency of waste discharge are difficult to match with the high-speed production equipment, making it impossible to achieve timely and efficient waste discharge and failing to solve the problem of waste treatment in industrial production. Utility Model Content

[0004] To address the aforementioned problems, the primary objective of this invention is to provide a reciprocating feeding and waste discharge device to solve the technical issues described above.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] This utility model provides a reciprocating feeding and waste discharge device, comprising:

[0007] The base has a bearing seat and a motor fixedly mounted on it. A rotating shaft is mounted on the bearing seat, a driven gear is mounted on the rotating shaft, and a driving gear is mounted on the output shaft of the motor. The driven gear and the driving gear are meshed and connected.

[0008] The transmission assembly and the waste container are provided. One end of the transmission assembly is connected to the waste container, and the other end of the transmission assembly is connected to the rotating shaft so that the waste container can be driven to reciprocate when the rotating shaft moves.

[0009] Preferably, a slanted frame is provided inside the waste container, with one end of the slanted frame being higher than the other end, so that the waste inside the waste container can move from one end of the slanted frame to the other end.

[0010] In one working scenario, the output shaft of the motor drives the drive gear to rotate, the drive gear drives the transmission gear to rotate, the transmission gear drives the rotating shaft to rotate, and the rotating shaft drives the transmission assembly to rotate, thereby driving the waste container to reciprocate.

[0011] Compared with existing technologies, the advantages of this invention are: this device only requires a "motor-gear-rotating shaft-transmission assembly" to achieve reciprocating motion, eliminating the need for additional pneumatic sources, air pipes, and other auxiliary components, thus greatly simplifying the structure, improving operational stability, and saving costs. Furthermore, this device boasts high efficiency, good safety, and seamless integration with automated production lines, making it of significant practical importance and market value.

[0012] Furthermore, the transmission assembly includes a rocker arm and a swing arm. The first end of the rocker arm is connected to the waste container, the second end of the rocker arm is connected to the first end of the swing arm, and the second end of the swing arm is connected to the rotating shaft.

[0013] Preferably, the second end of the swing arm is provided with a swing arm groove, and the upper end of the rotating shaft is embedded in the swing arm groove to reduce the height of the feeding and waste discharge device, thereby reducing the footprint of the feeding and waste discharge device, so that the device can be used in workstations with lower height.

[0014] Furthermore, the transmission assembly also includes a first equal-height screw and a second equal-height screw;

[0015] The rocker arm has a first rocker arm through hole at its first end and a second rocker arm through hole at its second end; the swing arm has a first swing arm through hole at its first end; and the waste collection box has a waste material through hole.

[0016] The first leveling screw passes through the first rocker arm through hole and the waste material through hole. The first leveling screw is movably connected to the first rocker arm through hole so that the first end of the rocker arm is movably connected to the waste material container.

[0017] The second leveling screw passes through the second rocker arm through hole and the first swing arm through hole. The second leveling screw is movably connected to the second rocker arm through hole to realize the movable connection between the second end of the rocker arm and the first end of the swing arm.

[0018] In a working scenario, the rotating shaft drives the swing arm to rotate, making circular motion with the second end of the swing arm as the center. At the same time, the first end of the swing arm drives the second end of the rocker arm to make circular motion, and the second end of the rocker arm swings back and forth with the second equal-height screw as the center, thereby driving the first end of the rocker arm to make reciprocating motion. At the same time, the first end of the rocker arm swings back and forth with the first equal-height screw as the center.

[0019] Preferably, a gap is formed between the first end of the rocker arm and the waste container to prevent the waste container from obstructing the movement of the first end of the rocker arm and generating noise, while making the transmission movement between the drive shaft and the swing arm smoother.

[0020] Furthermore, the joystick includes a first joint and a second joint. The first joint includes a first joint body and a first bearing, and the second joint includes a second joint body and a second bearing.

[0021] The first joint body has a first bearing through hole, the first bearing is embedded in the first bearing through hole, the first bearing is movably connected to the first bearing through hole, and the first bearing has a first rocker arm through hole; the first bearing is embedded in the first joint body, which enhances the smoothness of the rotation of the first joint and makes the back-and-forth swing of the first joint smoother.

[0022] The second joint body has a second bearing through hole, and the second bearing is embedded in the second bearing through hole and movably connected to the second bearing through hole. The second bearing also has a second rocker arm through hole. Embedding the second bearing in the second joint body enhances the smoothness of the second joint's rotation, making the back-and-forth swing of the second joint smoother.

[0023] Furthermore, the joystick also includes a double-ended rod. The first joint has a first bearing connection groove, and the second joint has a second bearing connection groove. The two ends of the double-ended rod are respectively embedded in the first bearing connection groove and the second bearing connection groove. Through this design, the length of the joystick can be quickly adjusted to adapt to various installation scenarios, improving the fault tolerance rate and thus greatly optimizing the installation process of the device.

[0024] Preferably, the two ends of the double-ended rod are respectively provided with external threads, and the first bearing connecting groove and the second bearing connecting groove are respectively provided with internal threads, and the two ends of the double-ended rod are respectively threadedly connected to the first bearing connecting groove and the second bearing connecting groove.

[0025] Furthermore, the bearing housing also includes a height adjusting member that abuts against the bottom of the driven gear to adjust the height of the driven gear, thereby achieving meshing between the driving gear and the driven gear.

[0026] Preferably, a protrusion is formed on the side of the rotating shaft, and an external thread is provided on the protrusion. The inner surface of the height adjusting member is provided with an internal thread adapted to the external thread. The height adjusting member abuts against the bottom of the driven gear, so as to adjust the height of the driven gear by adjusting the height of the driven gear, thereby realizing the meshing between the driving gear and the driven gear. In some embodiments, the height adjusting member can be a height adjusting nut.

[0027] Furthermore, a locking through hole is provided on the driven gear, and a locking groove is recessed on the side of the rotating shaft.

[0028] The bearing housing also includes a locking element. The driven gear is sleeved on the rotating shaft. The locking groove and the locking through hole form a locking space.

[0029] Furthermore, the feeding and waste discharge device also includes a motor mount, on which the motor is mounted. The motor mount is movably connected to the base to adjust the relative position between the motor mount and the bearing housing. This, in turn, adjusts the relative position between the driven gear and the driving gear. Through the matching arrangement of the height adjustment component and the motor mount, the spatial positions of the driven gear and the driving gear can be adjusted simultaneously to better achieve meshing between them.

[0030] Preferably, a slotted through hole is provided on the motor base, and a fixing through hole is provided on the base. The width of the slotted through hole is greater than the width of the fixing through hole. Screws are correspondingly provided with the fixing through holes, and the screws can pass through any area within the slotted through hole to connect with the fixing through hole to adjust the position of the motor. After adjusting the position of the motor, the screws are tightened to fix the motor on the base.

[0031] Furthermore, the feeding and waste discharge device also includes a limiting component. One end of the limiting component is connected to the waste container, and the other end of the limiting component is connected to the base to restrict the movement direction of the waste container, thereby realizing the linear reciprocating motion of the waste container.

[0032] Furthermore, the limiting component includes a fixed seat, a guide shaft, and a sliding seat. One end of the fixed seat is fixedly connected to the base, and the other end of the fixed seat is fixedly connected to the guide shaft. One end of the sliding seat has a sliding through hole, and the sliding seat is movably connected to the guide shaft by being sleeved on the guide shaft through the sliding through hole. The other end of the sliding seat is fixedly connected to the waste container.

[0033] In a working scenario, a rotating shaft drives a swing arm to rotate, making circular motion around the second end of the swing arm as the center. Simultaneously, the first end of the swing arm drives the second end of the rocker arm in circular motion, while the second end of the rocker arm swings back and forth around the second level screw as the center, thus driving the first end of the rocker arm in reciprocating motion. While the first end of the rocker arm performs linear reciprocating motion, it also swings back and forth around the first level screw as the center. The sliding seat performs linear reciprocating motion along the guide shaft. Under the combined action of the sliding seat and the rocker arm, the waste container performs linear reciprocating motion.

[0034] Furthermore, magnetic mounting bases are installed at both ends of the base. A switch knob is provided on each magnetic mounting base. When the switch knob is turned to the open position, the magnetic mounting base becomes magnetic, thus magnetically securing the base; when the switch knob is turned to the closed position, the magnetic mounting base becomes demagnetized, allowing for flexible installation and handling of the feeding and waste discharge device.

[0035] Compared with existing technologies, the advantages of this invention are: this device only requires a "motor-gear-rotating shaft-transmission assembly" to achieve reciprocating motion, eliminating the need for additional pneumatic sources, air pipes, and other auxiliary components, thus greatly simplifying the structure, improving operational stability, and saving costs.
