[0002] Washing machines are one of the most common household appliances currently. They can save the step of hand washing. You can directly put the clothes into the washing machine and pour in the detergent. After a period of time, the clothes will be automatically washed and can be taken out and dried. It is very convenient.

[0003] Among them, Jide washing machine is a common washing machine brand on the market. Its door outer ring is injection molded. Figure 1 , Figure 2 As shown in the figure, 1, 2, and 3 are the gate positions respectively. There are flashes on the inner edge 5 and the outer edge 4, which need to be trimmed before entering the subsequent assembly process. However, due to the large volume of the door outer ring product, the manual trimming speed is very slow and the efficiency is low. In addition, the gate 6 at the bottom of the door outer ring must be removed during the trimming, which is troublesome to operate. Summary of the invention

[0004] In order to solve the problems of low efficiency and high strength of manual trimming of existing door outer rings, the present invention provides a fully automatic trimming machine for door outer rings, which can realize automatic trimming of door outer rings and improve efficiency.

[0005] The technical solution is as follows: a fully automatic trimming machine for the outer ring of a door, characterized in that it includes a machine platform, a main turntable is installed on the machine platform, the main turntable is connected to a first driving motor, an annular positioning block is arranged on the main turntable, a clamping mechanism and an outer ring trimming mechanism are arranged on the outer side of the main turntable, an inner ring trimming mechanism and a gate cutting mechanism are arranged on the inner side of the annular positioning block, the outer ring trimming mechanism includes a first rotating cylinder, a swing block is installed on the piston rod of the first rotating cylinder, an outer ring trimming head is installed on the swing block, the inner ring trimming mechanism includes a driving cylinder, an inner ring trimming head is installed on the piston rod of the driving cylinder, and the gate cutting mechanism includes pneumatic scissors.

[0006] It is further characterized in that the clamping mechanism comprises at least two second rotary cylinders, and a pressing wheel is mounted on the piston rod of each second rotary cylinder;

[0007] An auxiliary cylinder is arranged beside the first rotating cylinder, the cylinder body of the auxiliary cylinder is hinged to the machine platform, and the piston rod of the auxiliary cylinder is hinged to the swing block;

[0008] The inner ring trimming mechanism and the gate cutting mechanism are both installed on the middle turntable, and the middle turntable is connected to the second driving motor;

[0009] The main turntable is installed on a base, and the base is connected to the machine through a connecting rod. The main turntable has a middle through hole, and the intermediate turntable is connected to the second driving motor through a rotating shaft passing through the through hole. The main turntable and the intermediate turntable rotate independently of each other.

[0010] After adopting the present invention, the outer ring of the door is placed on the annular positioning block and pressed to achieve clamping, the pneumatic scissors on the gate cutting mechanism extend and cut the gate, the main turntable rotates to drive the outer ring of the door to rotate, the inner ring trimming head and the outer ring trimming head respectively trim the inner edge and the outer edge of the outer ring of the door, thereby realizing automatic trimming of the outer ring of the door and improving efficiency.

[0020] See Figures 3 to 9As shown, a fully automatic trimming machine for the outer ring of a door comprises a machine platform 9, a main turntable 18 is mounted on the machine platform 9, the main turntable 18 is connected to a first drive motor 19, an annular positioning block 20 is arranged on the main turntable 18, a clamping mechanism and an outer ring trimming mechanism are arranged on the outer side of the main turntable 18, the clamping mechanism comprises two second rotary cylinders 11, a pressing wheel 17 is mounted on the piston rod of each second rotary cylinder 11, and is used to press the outer ring 13 of the door to prevent scratches by using its rolling characteristics; the outer ring trimming mechanism It includes a first rotating cylinder 26, a swing block 21 is installed on the piston rod of the first rotating cylinder 26, an outer ring trimming head 22 is installed on the swing block 21, an inner ring trimming mechanism and a gate cutting mechanism are arranged on the inner side of the annular positioning block 20, the inner ring trimming mechanism includes a driving cylinder 23, an inner ring trimming head 24 is installed on the piston rod of the driving cylinder 23, and the gate cutting mechanism includes pneumatic scissors 25, which are purchased parts from the market, and the scissors can be extended and sheared respectively under the action of two cylinders. In the figure, 7 is an emergency stop switch, 8 is a start switch, 10 is a guardrail, 12 is a laser proximity switch for detecting the outer ring 13 of the door, 14 is a reflector matched with the proximity switch, 15 is a touch screen, and 16 is an air valve

[0021] In order to achieve a better outer ring dressing effect, an auxiliary cylinder 27 is arranged next to the first rotary cylinder 26. The cylinder body of the auxiliary cylinder 27 is hinged to the machine table, and the piston rod of the auxiliary cylinder 27 is hinged to the swing block 21, which is used as a telescopic connecting rod and is not ventilated.

[0022] The inner ring trimming mechanism and the gate cutting mechanism are both mounted on the intermediate rotating disk 28, and the intermediate rotating disk 28 is connected to the second driving motor 29;

[0023] The main turntable 18 is installed on the base 30, and the base 30 is connected to the machine 9 through a connecting rod 31. The main turntable 18 has a middle through hole, and the intermediate turntable 28 is connected to the second drive motor 29 through a rotating shaft 32 passing through the through hole. The main turntable 18 and the intermediate turntable 28 rotate independently of each other.

[0024] The working principle of the present invention is as follows: first place the door outer ring 13 on the main turntable 18, and position it by the annular positioning block 20. The second rotating cylinder 11 drives the pressure block 17 to rotate and press it on the door outer ring 13 to fix it. The pneumatic scissors 25 extend and cut off the gate and then reset. Then the inner ring trimming head 24 and the outer ring trimming head 22 are pushed against the inner and outer edges of the door outer ring respectively under the drive cylinder 23 and the first rotating cylinder 26. The door outer ring 13 rotates one circle driven by the main turntable 18, and the outer ring trimming head 22 completes the trimming of the outer edge. In order to achieve a better inner edge trimming effect, the middle turntable 28 drives the inner ring trimming head 24 to rotate one circle to achieve inner edge trimming. The trimmed door outer ring 13 can be taken out.
