[0002] With the continuous development of social economy and the increasing level of science and technology, my country's chemical industry is also developing continuously. In the chemical industry, liquid chemicals are generally packaged by filling to facilitate the storage and transportation of chemicals.

[0003] In the prior art, there is an automatic filling device for chemical industry, which includes a frame, on which a conveying mechanism, a filling mechanism and a cover mechanism are arranged, and the conveying mechanism is used to convey the filling bottles. The filling mechanism includes a storage box, a conveying pipe and a filling head, the storage box is fixedly mounted on the frame, one end of the conveying pipe is connected to the storage box, and the other end is connected to the filling head, the filling head is fixedly mounted on the frame and is located above the conveying mechanism. The cover mechanism is used to place and tighten the cover body on the top of the filling bottle after filling. When in use, the conveying mechanism conveys the filling bottle to the bottom of the pipe pile head, and then the filling head conveys the chemical product in the storage box to the filling bottle, and then the conveying mechanism transports the filling bottle containing the chemical product to the bottom of the cover mechanism, so that the cover mechanism tightens the cover body on the bottle mouth of the filling bottle.

[0004] Regarding the above-mentioned related technologies, since the filling head is fixed and located directly above the filling bottle, there is a height difference between the filling head and the filling bottle. This means that when the filling head passes the chemicals in the storage box downward into the bottle mouth of the filling bottle, the falling chemicals are likely to splash out of the filling bottle, thereby causing leakage of the chemicals, so there is room for improvement.

The lifting assembly 52 includes a rotating member 521 and a lifting screw 522. In the embodiment of the present application, the rotating member 521 is set as a servo motor, and a brake device is set on the servo motor. The brake device is used to lock the output shaft when the output shaft of the servo motor stops, so as to ensure the current position of the lifting frame 51.

[0037] Reference Figure 1 and Figure 3 The servo motor is fixedly mounted on the frame 1 and is located above the above-mentioned string-type conveyor. The output shaft of the servo motor is fixedly connected to the top of the lifting screw 522 through a coupling, and the lifting screw 522 is vertically arranged. Both ends of the lifting screw 522 are rotatably connected to the frame 1 through bearings, and the bottom end of the lifting screw 522 passes downward through the lifting frame 51 and is threadedly connected to the lifting frame 51 to achieve the driving of the lifting frame 51 to slide.

[0039] Reference Figure 1 and Figure 2 The frame 1 is also provided with a positioning assembly 6, which is located directly below the lifting frame 51. The positioning assembly 6 includes a positioning frame 61 and a positioning cylinder 62. The positioning frame 61 and the positioning cylinder 62 are both provided in two numbers and are provided one by one.

[0040] Reference Figure 1 and Figure 2 Each positioning cylinder 62 is fixedly mounted on the frame 1, and the piston rod is extended in the direction close to the other positioning cylinder 62. The piston rod of each positioning cylinder 62 is fixedly connected to the corresponding positioning frame 61, and by driving the corresponding positioning frame 61 to move, the two positioning frames 61 clamp the filling bottle, thereby realizing the clamping and positioning of the filling bottle.

[0041] Reference Figure 1 , Figure 2 and Figure 3, the frame 1 is also provided with an upper cover mechanism 7, which includes an upper cover frame 71, a rotating assembly 72 and a conveying assembly 73. The conveying assembly 73 includes a conveyor belt 731 and a plurality of conveyor racks 732. The conveyor belt 731 is installed on the frame 1 and is used to convey objects placed on its upper surface. The conveyor belt 731 is inclined upward along its own length direction and close to one end of the lifting frame 51. The plurality of conveyor racks 732 are evenly and equidistantly distributed along the conveying direction of the conveyor belt 731, and are all fixedly connected to the surface of the conveyor belt 731, so that the conveyor rack 732 can drive the cover body to move by abutting against the cover body on the conveyor belt 731 during the movement, thereby realizing the conveying of the cover body.

[0042] Reference Figure 3 and Figure 4 The upper cover frame 71 is located between the conveying assembly 73 and the filling head 33, and when the bottom end of the filling head 33 is located in the filling bottle below, the end of the upper cover frame 71 close to the filling head 33 is tilted upward and is not located on the displacement path of the filling head 33.

[0043] Reference Figure 3 and Figure 4 In the initial state, that is, when the inclination angle of the upper cover frame 71 is consistent with the inclination angle of the conveyor belt 731, the end of the upper cover frame 71 close to the conveyor belt 731 is close to the conveyor belt 731, so that the cover body on the conveyor belt 731 can be smoothly pushed by the conveyor frame 732 and transported to the conveyor belt 731.

[0044] Reference Figure 3 and Figure 4 The end of the upper cover frame 71 away from the filling head 33 is rotatably connected to the frame 1 through a pin shaft, and is located at the top bottle mouth of the filling bottle just below the filling head 33, and is located on the extension path of the rotation trajectory of the upper cover frame 71, so that when the upper cover frame 71 rotates, it can place the cover body placed on it at the bottle mouth of the top of the filling bottle.

[0045] Reference Figure 3 and Figure 4 , a clamping assembly 74 is provided on the upper cover frame 71, and the clamping assembly 74 includes a plurality of clamping frames 741. In the embodiment of the present application, the number of the clamping frames 741 is set to two. The two clamping frames 741 are respectively located on both sides of the upper cover frame 71 along the width direction of the conveyor belt 731, and a cover body is placed between the two clamping frames 741. The main body parts of the two clamping frames 741 are both arc-shaped, so that the inner wall thereof is fully attached to the outer wall of the cover body, and a groove is provided on one side wall of the clamping frames 741 close to each other, so that the side end of the cover body is embedded in the groove, reducing the probability of the cover body falling.

[0046] Reference Figure 3 and Figure 4Each clamping frame 741 has a sliding portion 7411 extending in a direction away from the other clamping frame 741 , each sliding portion 7411 passes through the side wall of the upper cover frame 71 , and is slidably connected to the upper cover frame 71 , and the sliding direction is the width direction of the conveyor belt 731 .

[0047] Reference Figure 3 and Figure 4 , each sliding part 7411 is provided with an elastic member 742, and in the embodiment of the present application, the elastic member 742 is configured as a pressure spring. Each of the pressure springs is sleeved on the corresponding sliding part 7411 and is located between the main body of the clamping frame 741 and the side wall of the upper cover frame 71. One end of each of the pressure springs abuts against the main body of the clamping frame 741, and the other end abuts against the inner side wall of the upper cover frame 71, so that the clamping frame 741 is reset by its own elastic force.

[0048] Reference Figure 3 and Figure 4 A contact portion 7412 extends from one end of the main body of each clamping rack 741 close to the conveying rack, and each contact portion 7412 is inclined in a direction away from the other clamping rack 741 .

[0049] Reference Figure 3 and Figure 4 In the initial state, when there is no cover on the upper cover frame 71, the two clamping frames 741 approach each other, and the inclination angle of the upper cover frame 71 is consistent with the inclination angle of the conveyor belt 731. When the conveyor belt 731 runs and drives the conveyor frame 732 to move, the conveyor frame 732 pushes the corresponding cover to move, so that the cover gradually slides onto the upper cover frame 71. In this process, the cover gradually abuts against the abutment portion 7412 on the clamping frame 741, so that the clamping frame 741 slides and gradually opens, so that the cover can slide between the two clamping frames 741 and clamp the cover.

[0050] Reference Figure 3 and Figure 4 The rotating assembly 72 includes a sliding frame 721, a transmission frame 722 and a linkage member 723, and the linkage member 723 includes a linkage frame 7231. The number of the sliding frame 721 and the linkage frame 7231 is set to two, and the sliding frame 721 and the linkage frame 7231 are arranged one by one. The two linkage frames 7231 are respectively located on opposite sides of the upper cover frame 71, and the top end of each linkage frame 7231 is rotatably connected to the lifting frame 51 through a pin shaft, and the other end is rotatably connected to the corresponding sliding frame 721 through a pin shaft.

[0051] Reference Figure 1 , Figure 3 and Figure 4Each sliding frame 721 is slidably connected to the frame 1 through a slide rail, and the sliding direction of the sliding frame 721 is perpendicular to the rotation axis of the upper cover frame 71. The number of transmission frames 722 is set to two, and they are respectively located on opposite sides of the upper cover frame 71 and correspond to the sliding frames 721. One end of each transmission frame 722 is rotatably connected to the corresponding sliding frame 721 through a pin shaft, and the other end is rotatably connected to the upper cover frame 71 through a pin shaft. The rotation axis of the upper cover frame 71 and the transmission frame 722 is different from the rotation axis of the upper cover frame 71 and the frame 1.

[0052] Reference Figure 3 and Figure 4 In the initial state, that is, when the bottom end of the filling head 33 is located on the upper side of its own displacement path, the bottom end of the filling head 33 does not extend into the filling bottle below. At this time, the sliding frame 721 is located on the side of its own sliding path close to the lifting frame 51, and the inclination angle of the upper cover frame 71 is the same as the inclination angle of the conveyor belt 731, so that the conveying assembly 73 can convey the cover body to the upper cover frame 71.

[0053] Reference Figure 3 and Figure 4 When the filling head 33 slides downward under the drive of the lifting frame 51, the filling head 33 drives the linkage frame 7231 to slide together. At this time, the linkage frame 7231 drives the sliding frame 721 to gradually slide away from the lifting frame 51, so that the sliding frame 721 drives the upper cover frame 71 to rotate upward through the conveying frame to avoid the filling head 33. When the filling head 33 descends to the bottom of the filling bottle, the sliding frame 721 is located at the end of its own sliding path farthest from the lifting frame 51.

[0054] Reference Figure 3 and Figure 4 When the filling head 33 gradually moves upward, the sliding frame 721 gradually slides toward the direction close to the lifting frame 51, and the upper cover frame 71 gradually approaches the filling bottle below. After the filling head 33 is separated from the filling bottle and moves higher than the height in the initial state, the upper cover frame 71 gradually approaches the filling bottle, and the cover body on the upper cover frame 71 gradually moves to the bottle mouth at the top of the filling bottle, thereby realizing the upper cover operation.

[0055] Reference Figure 1 , Figure 3 and Figure 4, each sliding part 7411 is provided with an arc-shaped guide surface at the bottom of one end away from the main body of the corresponding clamping frame 741. The frame 1 is also provided with a plurality of abutment frames 75. In the embodiment of the present application, the number of abutment frames 75 is set to two, and they are arranged one by one corresponding to the sliding part 7411, and are respectively located on both sides of the corresponding filling bottle. The top end of each abutment frame 75 is located on the displacement path of the sliding part 7411 on the corresponding clamping frame 741, so that the guide surface on the corresponding sliding part 7411 can abut against the abutment frame 75, thereby pushing the sliding part 7411 to slide.

[0056] Reference Figure 3 and Figure 4 Each abutting frame 75 is slidably connected to the machine body, and the sliding direction is opposite to the sliding direction of the sliding frame 721. The sliding path of each abutting frame 75 extends to the side of the corresponding filling bottle, so that the abutting frame 75 can avoid the filling bottle after sliding, ensuring the smooth transportation of the filling bottle by the conveying mechanism 2.

[0057] Reference Figure 3 and Figure 4 A driving frame 76 is provided on each abutting frame 75 , one end of each driving frame 76 is rotatably connected to the corresponding abutting frame 75 through a pin shaft, and the other end of each driving frame 76 is rotatably connected to the lifting frame 51 through a pin shaft.

[0058] Reference Figure 3 and Figure 4 In the initial state, that is, when the upper cover frame 71 is not close to the filling bottle, the abutting frame 75 is located on the side of its own sliding path away from the lifting frame 51. When the upper cover frame 71 gradually approaches the filling bottle, the lifting frame 51 drives the abutting frame 75 to slide in the direction close to the filling bottle through the driving frame 76, and makes the abutting frame 75 gradually located below the end of the sliding part 7411 of the corresponding clamping frame 741 with a guide surface. In the process of the upper cover frame 71 continuing to rotate downward, the bottom of the end of the sliding part 7411 of the clamping frame 741 with a guide surface gradually abuts against the corresponding abutting frame 75, so that the two clamping frames 741 are separated from each other, and then the clamping frame 741 gradually releases the clamping of the cover body. When the cover body is placed on the filling bottle, the clamping frame 741 is completely separated from the cover body to achieve the placement of the cover body.

[0059] Reference Figure 1 The capping mechanism 4 is located on the side of the upper cover mechanism 7 away from the storage box 31. The capping mechanism 4 is used to tighten the cover body onto the filling bottle. In the embodiment of the present application, the capping mechanism 4 is configured as a combined structure consisting of a mechanical claw and a driving device for driving the mechanical claw to rotate and lift, thereby realizing the clamping and rotation of the cover body.

[0060] The implementation principle of the automatic filling equipment for chemical industry in the embodiment of the present application is as follows: when filling is required, the filling head 33 slides downward under the drive of the lifting frame 51 and gradually extends into the filling bottle. In this process, the lifting frame 51 drives the upper cover frame 71 to rotate through the linkage frame 7231, the sliding frame 721 and the transmission frame 722, so as to avoid the filling head 33. When the filling head 33 descends to the bottom of the filling bottle, the sliding frame 721 is located at the end of its own sliding path farthest from the lifting frame 51.

[0061] When the filling head 33 moves upward, the sliding frame 721 drives the upper cover frame 71 to rotate downward through the transmission frame 722, so that the upper cover frame 71 gradually approaches the filling bottle, so that the cover body gradually moves and is placed on the bottle mouth at the top of the filling bottle. In this process, the bottom of the sliding part 7411 of the clamping frame 741, which has a guide surface at one end, gradually abuts against the corresponding abutting frame 75, so that the two clamping frames 741 move away from each other, so that the clamping frame 741 gradually releases the clamping of the cover body. After the upper cover is completed, the conveying mechanism 2 transports the filling bottle to the capping mechanism 4, so that the capping mechanism 4 tightens the cover body on the filling bottle.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
