Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for packaging bag printing, and in particular to an ink mixing device for packaging bags. Background Technology

[0002] In the production of food packaging bags, different color inks need to be mixed to print brand logos and nutrition facts. The device can precisely control the pigment ratio to ensure that the colors meet food safety standards. In the processing of daily chemical product packaging bags, special color inks are mixed through the ink mixing device to meet the needs of pearlescent, fluorescent and other effects for the colorful patterns of washing and care products.

[0003] The prior art patent document CN216856564U discloses a special ink mixing device for green printing of packaging bags, which solves the shortcomings of general ink mixing devices that cannot mix multiple colors and clean the inner wall. The device includes a housing, in which an ink mixing box and several ink tanks are fixedly installed in the middle and top of the housing, respectively. A rotating shaft is connected to the ink mixing box by a bearing, which runs through and extends to the outside of the bottom of the ink mixing box. A stirring blade is spirally welded on the rotating shaft, and stirring rods distributed vertically are welded on both sides of the rotating shaft. A scraper is welded to the end of each of the stirring rods. The device is driven by an external power source, and multiple ink tanks can supply ink to the ink mixing box. A water inlet pipe adds washing water to the ink mixing box to clean it, so as to avoid ink residue affecting the mixing of other colors and achieve the purpose of multiple ink mixing. At the same time, the rotating shaft in the ink mixing box not only has stirring blades for thorough mixing, but also scrapers for cleaning the inner wall of the ink mixing box.

[0004] In the existing technology, insufficient mixing of ink mixing devices leads to uneven ink composition, resulting in color differences, stripes, and color blocks in the packaging bag pattern during printing, affecting the consistency of appearance. Insufficient dispersion of pigment particles easily clogs the printing nozzle, and the ink has poor stability, easily separating after storage, requiring frequent machine shutdowns for stirring, and scrapping the entire batch of packaging bags, increasing cost losses.

[0005] The purpose of this invention is to provide an ink mixing device for packaging bags, which solves the problem of insufficient mixing in ink mixing devices.

[0006] To achieve the above objectives, this utility model provides an ink mixing device for packaging bags, including a device body and a water pump. A control panel is fixedly connected to the outside of the device body, and multiple ink tanks are provided on the top of the device body. An electric control valve is fixedly connected to the outside of each ink tank. A mixing mechanism is fixedly connected inside the device body, and a cleaning mechanism is fixedly connected to the outside of the water pump.

[0007] The mixing mechanism includes a motor, which is externally fixedly connected to the top of the device body. A drive rod is fixedly connected to the drive end of the motor.

A connecting rod is fixedly connected to the bottom of the gear. Multiple stirring blades are fixedly connected to the outside of the connecting rod. A rotating assembly is rotatably connected inside the device body.

[0008] The cleaning mechanism includes an annular tube, which is fixedly connected to the outside of the device body. Multiple nozzles are fixedly connected to the outside of the annular tube. A connecting pipe is fixedly connected to the outside of the water pump, and the connecting pipe is fixedly connected to the output shaft of the water pump.

[0009] The rotating assembly includes an L-shaped plate, which is fixedly connected to the outside of the drive rod, and a gear ring is fixedly connected to the outside of the L-shaped plate.

[0010] The device body has a water inlet pipe fixedly connected to its outer left side and a discharge pipe fixedly connected to its outer side.

[0011] The annular tube is fixedly connected to a connecting sleeve, and the connecting sleeve is fixedly connected to the outside of the connecting tube.

[0012] The active rod is externally fixedly connected to multiple scrapers, which are externally rotatably connected to the inside of the device body.

[0013] The gear is fixedly connected to the outside of the connecting plate, the gear ring is fixedly connected to the outside of the L-shaped plate, and the outside of the gear is meshed with the outside of the gear ring.

[0014] The device body is fixedly connected to an ink outlet pipe, and the feed pipe is located at the bottom of the device body.

[0015] 1. The present invention relates to an ink mixing device for packaging bags. The device uses a motor to drive the active rod, which in turn drives the connecting plate to drive the gear, which in turn drives the connecting rod to drive the stirring blade. This achieves thorough mixing, ensuring uniform distribution of ink components, guaranteeing consistent printing color on the packaging bags, avoiding color differences that could affect the product's appearance, reducing the sedimentation of high-viscosity ink, improving ink flowability, and making printing smoother.

[0016] 2. The present invention relates to an ink mixing device for packaging bags. By starting a water pump, water is transported through a connecting pipe to an annular pipe, which cleans the inside of the nozzle. At the same time, a scraper driven by a motor repeatedly cleans the inner wall, thereby achieving automatic cleaning. This can remove residual ink from the inner wall and components of the ink mixing box, avoid cross-contamination between different batches of ink, reduce the impact of residue on the next ink mixing, and help continuous and stable production.

[0023] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0024] Please see Figure 1 Figure 3This utility model provides a technical solution: an ink mixing device for packaging bags, including a device body 1 and a water pump 2. A control panel 3 is fixedly connected to the outside of the device body 1. The control panel 3 is a rectangular flat plate structure, embedded on the front top of the device body 1. Multiple circular buttons and a rectangular display screen are distributed on the surface. The buttons have clear function labels. The device can be operated and various parameters can be displayed. Multiple ink tanks 4 are set on the top of the device body 1. The ink tanks 4 are transparent cylindrical tanks with a sealing cap on the top and a funnel-shaped bottom. They are evenly arranged on the edge of the top of the device body 1, allowing for direct observation of the remaining ink. They are used to store printing inks of different colors. An electric control valve 5 is fixedly connected to the outside of the ink tanks 4. The electric control valve 5 is a cylindrical valve body, installed at the outlet at the bottom of the ink tanks 4, and connected to the funnel-shaped bottom of the ink tanks 4. The valve opening and closing size can be controlled by an electrical signal to precisely adjust the ink flow rate and flow. A mixing mechanism 6 is fixedly connected inside the device body 1, and a cleaning mechanism 9 is fixedly connected to the outside of the water pump 2.

[0025] The mixing mechanism 6 includes a motor 61, which is fixed at the center of the top of the device body 1. The output shaft extends vertically downward into the interior of the device body 1, providing continuous and stable rotational power. The motor 61 is externally fixedly connected to the top of the device body 1. The drive end of the motor 61 is fixedly connected to a drive rod 62, which is a solid cylindrical rod. The top end is coaxially fixed with the output shaft of the motor 61, and the bottom end extends downward into the lower part of the internal cavity of the device body 1. It can rotate at high speed with the drive of the motor 61. A connecting plate 63 is rotatably connected to the outside of the drive rod 62. The connecting plate 63 is a circular flat plate with a circular hole in the middle that matches the active rod 62. It is sleeved on the outside of the active rod 62 through a bearing and can rotate freely around the active rod 62. Its edges extend horizontally in all directions. A fixing rod 64 is fixedly connected inside the connecting plate 63. A gear 65 is fixedly connected to the outside of the fixing rod 64. The center hole of the gear 65 is fixedly fitted with the bottom end of the fixing rod 64. The teeth are evenly distributed on the outer circumference and can move synchronously with the connecting plate 63. A connecting rod 66 is fixedly connected to the bottom of the gear 65. Multiple stirring blades 67 are fixedly connected to the outside of the connecting rod 66.

[0026] The stirring blade 67 is a rectangular thin plate, arranged along the length of the connecting rod 66. When rotating, it can generate a strong stirring and shearing effect on the ink. The rotating assembly 68 is rotatably connected inside the device body 1. The rotating assembly 68 includes an L-shaped plate 681. The L-shaped plate 681 is fixedly connected to the outside of the drive rod 62. A gear ring 682 is fixedly connected to the outside of the L-shaped plate 681. The gear ring 682 is fixed to the end of the horizontal rod of the L-shaped plate 681, and its center coincides with the axis of the drive rod 62. Gears meshing with gears 65 are distributed on its inner circumference. The gear 65 is fixedly connected to the outside of the connecting plate 63, and the gear ring 682 is fixedly connected to the outside of the L-shaped plate 681. The outside of the gear 65 meshes with the outside of the gear ring 682. When the driving rod 62 drives the L-shaped plate 681 and the gear ring 682 to rotate, the gear ring 682 drives the gear 65 to rotate around its own axis through meshing transmission. At the same time, the connecting plate 63 moves in a circular motion with the driving rod 62, so that the stirring blade 67 both revolves around the driving rod 62 and rotates on its own, realizing all-round stirring and mixing of the ink.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, the cleaning mechanism 9 includes an annular pipe 91, which is a circular pipe fixed inside the upper part of the device body 1 and fits against the inner wall of the device body 1, allowing the cleaning water to be evenly distributed. The annular pipe 91 is fixedly connected to the outside of the device body 1. Multiple nozzles 92 are fixedly connected to the outside of the annular pipe 91. The nozzles 92 are conical structures and are evenly distributed at the bottom of the annular pipe 91, with their openings facing the inside of the device body 1. When working, they can spray high-pressure water to rinse the internal components. The water pump 2 is fixedly connected to the outside of a connecting pipe 93, which is a cylindrical flexible hose with a certain degree of flexibility and can bend with the movement of the components. It can deliver the water output by the water pump 2 to the annular pipe 91. The outside of the connecting pipe 93 is fixedly connected to the output shaft of the water pump 2. The water inlet pipe 7 is fixedly connected to the left side of the outside of the device body 1. The water inlet pipe 7 is a cylindrical rigid pipe with one end connected to an external water source and the other end extending into the inside of the device body 1 to provide the device with the water required for cleaning and ink adjustment.

[0028] The device body 1 is externally fixedly connected to a discharge pipe 8, which is a cylindrical pipe with an inclined setting to facilitate the discharge of wastewater and residual ink after cleaning. The annular pipe 91 is externally fixedly connected to a connecting sleeve 94, which is a cylindrical sleeve with a sealing gasket on the inner wall to enhance the sealing of the connection with the connecting pipe 93 and prevent water leakage. The connecting sleeve 94 is externally fixedly connected to the outside of the connecting pipe 93. The active rod 62 is externally fixedly connected to multiple scrapers 95, which are rectangular plate structures evenly distributed along the circumference of the active rod 62 and fit against the inner wall of the device body 1. When the active rod 62 rotates, it can scrape off the residual ink on the inner wall. The scrapers 95 are externally rotatably connected to the inside of the device body 1. The device body 1 is externally fixedly connected to an ink outlet pipe 10. The discharge pipe 8 is externally located at the bottom of the device body 1. When cleaning, wastewater and scraped ink residue are discharged from the device body 1 through the discharge pipe 8.

[0029] Working principle: The motor 61 drives the active rod 62 to move, which in turn drives the connecting plate 63 to move. The edge of the connecting plate 63 extends horizontally, causing the gear 65 connected to the bottom of the fixed rod 64 to rotate. The L-shaped plate 681 fixed in the middle of the active rod 62 rotates with it. The annular internal gear ring 682 at the horizontal end of the L-shaped plate 681 rotates synchronously and meshes with the gear 65 to drive the transmission, causing the gear 65 to rotate around its own axis. At the same time, the connecting plate 63 moves in a circular motion with the active rod 62, and the connecting rod 66 at the bottom of the gear 65 moves accordingly. The stirring blades 67 on the outside of the gear revolve around the active rod 62 and rotate on their own, so as to stir and mix the inflowing ink in all directions.

[0030] When cleaning is required, the water pump 2 starts and delivers water to the annular pipe 91 above the device body 1 through the connecting pipe 93. The connecting pipe 93 and the annular pipe 91 are connected by the connecting sleeve 94. The nozzles 92, which are evenly distributed at the bottom of the annular pipe 91, spray high-pressure water to rinse the internal components. At the same time, the active rod 62 drives the external scraper 95 to rotate. The scraper 95 adheres to the inner wall of the device body 1 to scrape off residual ink. The wastewater and ink residue generated during cleaning are discharged through the discharge pipe 8 set at the bottom of the device body 1.

[0031] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
