Description

Technical Field

[0001] This utility model relates to the field of ink filling technology, and more specifically to a printing ink filling device. Background Technology

[0002] Printing ink filling equipment is a type of machinery specifically designed for ink filling and is an indispensable piece of equipment in the printing industry.

[0003] Chinese Patent Publication No. CN215403019U discloses an automatic filling device for printing ink, including a filling device body, a gantry frame, a clearing mechanism, a lifting mechanism, a conveyor belt, support legs, a mounting box, pads, a feeding pipe, a connector, a connecting pipe, a filling head, a valve, a mounting plate, and a filter screen. A conveyor belt is installed on one side of the top of the mounting box, and a gantry frame is installed on the other side of the top of the mounting box. The filling device body is installed on top of the gantry frame. This invention achieves the lifting of the filling head through the lifting mechanism, which facilitates adjusting the height of the filling head according to the different heights of the cans to be filled. It can fill cans of different heights without changing the filling head, improving the practicality of the equipment. The clearing mechanism uses high-pressure gas from an air pump to blow air through the filling head to clear blockages, preventing clogging and improving filling efficiency. Furthermore, it eliminates the need for manual cleaning, reducing labor costs.

[0004] However, the following shortcomings still exist: when the ink in the printing ink filling equipment is used up, the equipment needs to be stopped and the ink tank replaced. When the equipment is stopped, the ink container is often only half-filled. Intermittent filling will result in inconsistent product content, which will reduce product quality and increase production time. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a printing ink filling device to solve the problems existing in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a printing ink filling device, comprising an oil tank assembly, a conveying device fixedly connected to the inner side of the bottom end of the oil tank assembly, a clamping assembly fixedly connected to the top of the conveying device, the oil tank assembly comprising an ink tank, a pneumatic pipe connected to the top of the ink tank, a feeding pipe connected to one side of the ink tank, a support frame fixedly connected to the bottom of the ink tank, an air pump connected to the inner side of the support frame, a filling pipe connected to the bottom of the air pump, a first spring welded to the inner side of the bottom of the ink tank, a piston plate welded to the top of the first spring, a piston plate connected to the top end of the filling pipe and passing through the piston plate, a first plunger fixedly connected to the middle of the top of the piston plate, a first air cylinder movably sleeved on the top end of the first plunger, and the top end of the first air cylinder fixedly connected to the inner side of the top of the ink tank.

[0007] Furthermore, the conveying device includes a workbench, and a support frame is fixedly connected to the side of the workbench.

[0008] Furthermore, two fixed plates are fixedly connected to the top of the workbench, a conveyor belt is connected to one side of the two fixed plates by a rotating shaft, and a motor is bolted to one side of one of the fixed plates.

[0009] Furthermore, the rear shaft of the motor is connected to one end of the conveyor belt, and a clamping assembly is fixedly connected to the top of the conveyor belt.

[0010] Furthermore, the clamp assembly includes a clamp housing, a second spring is welded to the inner side of the bottom of the clamp housing, and a placement plate is welded to the top of the second spring.

[0011] Furthermore, a second air cylinder is fixedly connected to the middle of the bottom inner side of the fixture housing, a second plunger is movably sleeved on the top of the second air cylinder, a placement plate is fixedly connected to the top of the second plunger, and the first air pipe is connected to both sides of the second plunger.

[0012] Furthermore, one end of each of the two first air tubes is connected to a second air tube, one side of the top of each of the two second air tubes is connected to a third air tube, one end of each of the two third air tubes is movably sleeved with a movable rod, and one end of each of the two movable rods is fixedly connected to a clamping block.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model incorporates an oil tank device. When the ink in the ink tank gradually decreases, the spring force exceeds the weight of the ink, causing the piston plate to move upward. This causes the first plunger to compress the air in the first air cylinder into the ink tank, increasing the air pressure in the ink tank. The pressure forces the ink out of the ink tank and into the ink tank through the feed pipe, thus replenishing the ink. This invention helps solve the problem in printing ink filling equipment where the equipment needs to be stopped after the ink is used up to replace the ink tank. When stopping the equipment, the ink container is often only half-filled. Intermittent filling leads to inconsistent product content, which reduces product quality and increases production time.

[0015] 2. This utility model features a clamping assembly. The ink container is positioned on a placement plate, and the weight of the container compresses the second plunger, causing the airflow in the second air cylinder to flow into the first air pipe. After passing through the second air pipe, the airflow enters the third air pipe, which in turn pushes out the movable rod. The movable rod connects to a clamping block, and pushing out the movable rod causes the clamping block to move forward and clamp the container, which helps to improve the stability of ink filling.

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The printing ink filling equipment involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1 to 4 This utility model provides a printing ink filling equipment, including an oil tank device 1, a conveying device 2 fixedly connected to the inner side of the bottom end of the oil tank device 1, and a clamping assembly 3 fixedly connected to the top of the conveying device 2.

[0023] In this embodiment, it is necessary to specifically explain that the oil tank device 1 helps to solve the problem that when the ink in the printing ink filling equipment is used up, the equipment needs to be stopped to replace the ink tank. When the equipment is stopped, the ink container is often only half-filled. Intermittent filling will lead to inconsistent product content. The clamping assembly 3 helps to improve the stability of ink filling. The specific structure and working principle of the above components will be explained in detail later.

[0024] In a preferred embodiment, the oil tank device 1 includes an ink tank 101. A pneumatic pipe 102 is connected to the top of the ink tank 101, a feed pipe 103 is connected to one side of the ink tank 101, a support frame 104 is fixedly connected to the bottom of the ink tank 101, an air pump 105 is connected to the inner side of the support frame 104, a filling pipe 106 is connected to the bottom of the air pump 105, a first spring 107 is welded to the inner side of the bottom of the ink tank 101, a piston plate 108 is welded to the top of the first spring 107, the top end of the filling pipe 106 is connected to the piston plate 108 and passes through the piston plate 108, a first plunger 109 is fixedly connected to the middle of the top of the piston plate 108, a first air cylinder 110 is movably sleeved on the top end of the first plunger 109, and the top end of the first air cylinder 110 is fixedly connected to the inner side of the top of the ink tank 101.

[0025] In this embodiment, it is necessary to specifically explain that when the ink in the ink tank 101 gradually decreases, the elastic force of the first spring 107 is greater than the weight of the ink, causing the piston plate 108 to move upward. This causes the first plunger 109 to squeeze the air in the first air cylinder 110 into the ink tank, increasing the air pressure in the ink tank. The pressure forces the ink out of the ink tank and into the ink tank through the feed pipe 103, thus replenishing the ink tube. This helps to solve the problem that when the ink in the printing ink filling equipment is used up, the equipment needs to be stopped to replace the ink tank. When the equipment is stopped, the ink container is often only half-filled. Intermittent filling will lead to inconsistent product content, which will reduce product quality and increase production time.

[0026] In a preferred embodiment, the conveying device 2 includes a workbench 201, a support frame 104 fixedly connected to the side of the workbench 201, two fixed plates 202 fixedly connected to the top of the workbench 201, a conveyor belt 203 connected to one side of the two fixed plates 202 by a rotating shaft, a motor 204 bolted to one side of one fixed plate 202, a rotating shaft on the back of the motor 204 connected to one end of the conveyor belt 203, and a clamp assembly 3 fixedly connected to the top of the conveyor belt 203.

[0027] In a preferred embodiment, the clamp assembly 3 includes a clamp housing 301. A second spring 302 is welded to the inner side of the bottom of the clamp housing 301. A placement plate 303 is welded to the top of the second spring 302. A second air cylinder 304 is fixedly connected to the middle of the inner side of the bottom of the clamp housing 301. A second plunger 305 is movably sleeved at the top of the second air cylinder 304. The placement plate 303 is fixedly connected to the top of the second plunger 305. First air pipes 306 are pipe-connected to both sides of the second plunger 305. A second air pipe 307 is pipe-connected to one end of each of the two first air pipes 306. A third air pipe 308 is pipe-connected to one side of the top of each of the two second air pipes 307. Movable rods 309 are movably sleeved at one end of each of the two movable rods 309. A clamping block 310 is fixedly connected to one end of each of the two movable rods 309.

[0028] In this embodiment, it should be specifically explained that the ink container is located on the placement plate 303. The gravity of the container squeezes the second plunger 305, causing the airflow in the second air cylinder 304 to flow into the first air pipe 306. After being transmitted through the second air pipe 307, it enters the third air pipe 308, which in turn pushes out the movable rod 309. The movable rod 309 is connected to the clamping block 310. Pushing out the movable rod 309 causes 30 to move forward and clamp the container, which helps to improve the stability of ink filling.

[0029] The working principle of this utility model is as follows: When the ink in the ink tank 101 gradually decreases, the elastic force of the first spring 107 is greater than the weight of the ink, causing the piston plate 108 to move upward. This causes the first plunger 109 to squeeze the air in the first air cylinder 110 into the ink tank, increasing the air pressure in the ink tank. The pressure forces the ink out of the ink tank and into the ink tank through the feed pipe 103, thus replenishing the ink tube. This helps to solve the problem that when the ink in the printing ink filling equipment is used up, the equipment needs to be stopped to replace the ink tank. When the equipment is stopped, the ink container is often only half-filled. Intermittent filling will lead to inconsistent product content, which will reduce product quality and increase production time.

[0030] The ink container is located on the placement plate 303. The weight of the container squeezes the second plunger 305, causing the airflow in the second air cylinder 304 to flow into the first air pipe 306. After being transmitted through the second air pipe 307, it enters the third air pipe 308, which in turn pushes out the movable rod 309. The movable rod 309 is connected to the clamping block 310. Pushing out the movable rod 309 causes 30 to move forward and clamp the container, which helps to improve the stability of ink filling.
