Description

Technical Field

[0001] This application relates to the technical field of plunger manufacturing, and in particular to an automatic feeding device for plunger spraying. Background Technology

[0002] The plunger is a device that enables the cylinder to draw and pressurize oil. The plunger needs to move repeatedly, and as the automation and continuous operation of equipment in enterprises increase, surface wear and corrosion will also increase. Thermal spraying technology can be used to strengthen the surface of the plunger, and by using supersonic spraying of tungsten carbide coating, the wear resistance of the plunger can be effectively improved.

[0003] Existing plunger spraying equipment mostly requires fixing a single plunger on a rotating mechanism, and then using the rotation to drive the spraying equipment to spray the plunger. After spraying, the plunger needs to be cooled before it can be removed, which is inefficient and affects subsequent projects.

[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: the plunger needs to be fixed on the rotating bracket before spraying, and needs to be cooled before it can be removed after spraying, which is inefficient and affects subsequent processes. Utility Model Content

[0005] The purpose of this application is to provide an automatic feeding device for plunger spraying to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides an automatic feeding device for plunger spraying, employing the following technical solution:

[0007] An automatic feeding device for plunger spraying includes a disc support frame, a feeding conveyor belt disposed on one side of the disc support frame, and a discharging mechanism disposed on the other side of the disc support frame. A feeding disc is rotatably disposed inside the disc support frame, a bracket is fixed to the top of the feeding disc, and multiple placement mechanisms are fixed to the bottom of the bracket.

[0008] The placement mechanism includes an electric slide rail, an electric telescopic rod, a gripper, a baffle, a turntable, and a rotary motor. Multiple electric slide rails are arranged around the bottom of the support. An electric telescopic rod is fixed to the bottom of the electric slide rail. A gripper is rotatably connected to the end of the electric telescopic rod away from the electric slide rail. A baffle is provided at the bottom of the gripper. A turntable is provided on the inner side of the bottom of the baffle. The turntable passes through the feeding tray and is rotatably connected to the feeding tray. A rotary motor is fixed to the bottom of the turntable.

[0009] A stepper motor is fixedly connected to the center line of the bottom of the feeding tray. An automatic spray gun is fixed on the side of the disc support frame away from the feeding conveyor belt. A controller is provided on the top of the support frame. A pressure sensor is fixed on the top of the turntable.

[0010] By adopting the above technical solution, the worker places the plunger on the feed conveyor belt onto the turntable, where it is clamped in the gripper. After the pressure sensor on the turntable senses the pressure, it transmits the signal to the controller. The controller controls the electric telescopic rod to move downward, causing the gripper to squeeze and fix the plunger. Under the action of the controller, the stepper motor is controlled to rotate by an angle, so that the unpainted plunger reaches the position of the automatic spray gun. The controller controls the automatic spray gun to spray the plunger. The rotary motor drives the plunger to rotate on the turntable, which facilitates spraying around the plunger. After spraying, the controller controls the stepper motor to rotate by another angle, so that the plunger that has just been sprayed leaves, and a new unpainted plunger reaches the position of the automatic spray gun.

[0011] Preferably, the feeding tray is rotatably connected to the slide groove inside the disc support frame via a locking block surrounding the outer side.

[0012] By adopting the above technical solution, the feeding tray can be rotated easily, and the feeding tray can be supported at the same time.

[0013] Preferably, the plurality of the placement mechanisms are arranged in a circular array on the feeding tray.

[0014] By adopting the above technical solution, it is beneficial to continuously spray the plunger on the feeding tray.

[0015] Preferably, the cross-section of the baffle is U-shaped, and the horizontal plane of the turntable is lower than the horizontal plane of the feeding tray.

[0016] By adopting the above technical solution, the plunger is shielded to prevent it from affecting other areas during spraying, making it easier to place the plunger and preventing the bottom of the plunger from moving.

[0017] Preferably, the electric slide rail, electric telescopic rod, rotary motor, and stepper motor are all electrically connected to the controller.

[0018] By adopting the above technical solution, the controller can easily control the electric slide rail, electric telescopic rod, rotary motor and stepper motor to perform corresponding operations at appropriate times.

[0019] Preferably, the automatic spray gun is electrically connected to the controller, and the pressure sensor is electrically connected to the controller.

[0020] By adopting the above technical solution, the controller can easily control the automatic spray gun to spray, and the pressure sensor transmits the signal to the controller when it is under pressure.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. The placement mechanism allows the plunger to be placed on the turntable and continuously rotated to the automatic spray gun for spraying under the drive of the stepper motor. This reduces the process of removing the plunger after spraying and greatly improves production efficiency.

[0023] 2. The discharge mechanism allows the electric telescopic rod to pull up the sprayed plunger under the control of the controller, feed it into the discharge mechanism, and then discharge the plunger, making it convenient to use. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0029] This application discloses an automatic feeding device for plunger spraying, referring to... Figure 1-3 The system includes a disc support frame 1, a feeding conveyor belt 2 disposed on one side of the disc support frame 5, and a discharging mechanism 3 disposed on the other side of the disc support frame 1. The discharging mechanism 3 is composed of a conveying roller and a fixing clamp. The disc support frame 1 is rotatably provided with a feeding plate 4. The top of the feeding plate 4 is fixed with a bracket 5. The feeding plate 4 is rotatably connected to the sliding groove inside the disc support frame 1 through a locking block surrounding the outside, which facilitates the rotation of the feeding plate 4. The bottom of the bracket 5 is fixed with multiple placement mechanisms 6. The multiple placement mechanisms 6 are arranged in a ring array on the feeding plate 4 to facilitate the continuous feeding of plungers to the automatic spray gun 8.

[0030] The placement mechanism 6 includes an electric slide rail 61, an electric telescopic rod 62, a gripper 63, a baffle 64, a turntable 65, and a rotary motor 66. Multiple electric slide rails 61 are arranged around the bottom of the support 5. An electric telescopic rod 62 is fixed to the bottom of each electric slide rail 61. A gripper 63 is rotatably connected to the end of the electric telescopic rod 62 away from the electric slide rail 61. A baffle 64 is provided at the bottom of the gripper 63. The baffle 64 has a U-shaped cross-section to prevent spraying onto other parts of the turntable 65, thus affecting the equipment's service life. The horizontal plane of the turntable 65 is lower than the horizontal plane of the feeding tray 4, facilitating the electric telescopic rod 62 to press the plunger onto the turntable 65 and preventing the plunger's bottom from detaching from the turntable 65. The turntable 65 is located on the inner side of the bottom of the baffle 64. The turntable 65 passes through the feeding tray 4 and is rotatably connected to it. A rotary motor 66 is fixed to the bottom of the turntable 65.

[0031] A stepper motor 7 is fixedly connected to the bottom center line of the feeding tray 4. An automatic spray gun 8 is fixed on the side of the disc support frame 1 away from the feeding conveyor belt 2. A controller 9 is provided on the top of the bracket 5. A pressure sensor is fixed on the top of the turntable 65. The electric slide rail 61, electric telescopic rod 62, rotary motor 66 and stepper motor 7 are all electrically connected to the controller 9. The automatic spray gun 8 is electrically connected to the controller 9. The pressure sensor is electrically connected to the controller 9.

[0032] The implementation principle of the automatic feeding device 4 for plunger spraying in this application embodiment is as follows:

[0033] When using the device, the worker stands on one side of the feed conveyor belt 2 and sequentially places the plungers on the feed conveyor belt 2 into the grippers 63 on the turntable 65. The pressure sensor on the surface of the turntable 65 senses the pressure and transmits a signal to the controller 9. The controller 9 controls the electric telescopic rod 62 to move downwards, pressing down on the plungers. When the pressure sensor reaches the set value, the controller 9 controls the electric telescopic rod 62 to stop. After the automatic spray gun 8 finishes spraying one item, the controller 9 controls the stepper motor 7 to rotate by a certain angle to move the next item. After the plunger is rotated to the front of the automatic spray gun 8, the controller 9 controls the automatic spray gun 8 to spray the plunger. During spraying, the rotary motor 66 drives the plunger to rotate, which facilitates spraying one circumference of the plunger. After the spraying time is up, the controller 9 controls the stepper motor 7 to rotate again, sending out the sprayed plunger. When it reaches the position of the discharge mechanism 3, the controller 9 controls the corresponding electric telescopic rod 62 to move upward, so that the gripper 63 pulls up the plunger. The electric slide rail 61 drives the plunger to approach the discharge mechanism 3, and then sends out the sprayed plunger.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, principle and application direction of this application should be covered within the scope of protection of this application.
