Description

Technical Field

[0001] The utility model relates to the field of ink production equipment, in particular to an energy-saving stirring device for ink production. Background Art

[0002] Ink is an indispensable item in the printing industry. During production, ink needs to go through processes such as color adjustment, dispersion, and mixing to meet the product quality requirements before it leaves the factory. The mixing process requires a stirring device to complete. A common ink stirring device includes a stirring drum, a base, a drive motor, a vertically downward main shaft, and a stirring head connected to the lower end of the main shaft. The stirring head is provided with a stirring blade formed by large spiral blades (like the blades of a fan) that spread from the middle to the surroundings. The stirring blades on the stirring head are driven by the main shaft to rotate to stir the ink. The disadvantages of this existing stirring device are: 1. The stirring blade is large in size and has high resistance during stirring, which makes the driving motor consume a lot of power, is not energy-saving, and is not convenient to clean the stirring head; 2. The speed cannot be adjusted according to different requirements, and it is not convenient to use; 3. The stirring drum is fixed and inconvenient to move. The staff needs to use auxiliary equipment to transport it. Although the Chinese patent No. 202022981279X discloses a movable stirring drum, it uses a handle installed on the outer drum and a universal wheel installed on the bottom to achieve the movement of the stirring drum. However, the following issues still exist: 1. The U-shaped handle is connected to the outer wall of the mixing drum only by two welded feet. When the mixing drum is lifted and carried by the handle (especially when the mixing drum is still heavy and contains a large amount of ink), the welds are easily loosened due to excessive force, making the structure unreliable. 2. The stirring device and the mixing drum are two completely independent devices, which is not convenient to use.

[0003] Therefore existing ink production stirring device is difficult to meet the requirements of the majority of manufacturers. Summary of the Invention

[0004] The purpose of the utility model is to address the above-mentioned problems and shortcomings and to provide an energy-saving stirring device for ink production that is easy to use, energy-saving, and easy to clean, and has a reliable connection structure between the handle and the stirring drum and good stirring effect.

[0005] The technical solution of the present utility model is achieved as follows:

[0006] The energy-saving stirring device for ink production described in this utility model is characterized by comprising a stainless steel stirring drum, a drive mechanism mounted on the stirring drum, and a stirring head mounted at the bottom end of the output shaft of the drive mechanism and extending into the stirring drum. The stirring head is formed as a ratchet with ratchet teeth arranged around its periphery. A metal upper hoop is fixed to the upper portion of the outer wall of the stirring drum, and the upper hoop is provided with a handle. A liquid outlet pipe with a control valve is provided at the bottom of the stirring drum.

[0007] The handles can be front and rear handles welded to the upper hoop, each handle being reliably connected to the upper hoop by at least two welding legs; or they can be an annular handle arranged on the upper hoop, the annular handle being reliably connected to the upper hoop by at least four welding legs.

[0008] The upper hoop can be connected to the mixing drum as a whole by welding or bonding with strong glue.

[0009] Preferably, the handle is composed of a transverse handlebar and at least two welding legs which reliably connect the middle portion of the transverse handlebar to the upper hoop.

[0010] Furthermore, a lower hoop is provided at the bottom end of the outer wall of the mixing drum, and a plurality of universal wheels are connected to the lower hoop, so that the mixing drum can be displaced by means of the universal wheels.

[0011] Furthermore, a support rod is provided at the upper port of the mixing drum, and the drive mechanism is fixedly mounted on the support rod. The drive mechanism can be formed by a drive motor. Preferably, the drive mechanism is a drive motor and a transmission externally connected to the drive motor. There are two support rods at the upper port of the mixing drum, which are arranged in parallel to form a support frame, and a mounting plate is provided on the support frame. The drive motor is securely locked to the mounting plate by fastening screws. A storage cylinder located at the periphery of the drive motor can also be provided on the support frame, and the gap between the storage cylinder and the drive motor forms a cavity for the built-in concealment of the power connection line of the drive motor.

[0012] Furthermore, at least one guide block is installed at the lower part of the inner cavity wall of the mixing drum, and at least one of the left and right sides of the guide block has a guide bevel for guiding the material toward the middle of the mixing drum.

[0013] The beneficial effects of this application compared with the prior art are:

[0014] 1. The stirring head is changed from the existing large fan-type stirring blade to a ratchet structure with ratchet teeth around the periphery. Since the ratchet teeth are small in size, the resistance of the ink to the stirring head during rotation and stirring is greatly reduced. Therefore, the driving mechanism can also choose a driving motor with lower power consumption, which is energy-saving and environmentally friendly, and is extremely easy to clean.

[0015] Second, by replacing the traditional motor with a drive motor and an external transmission, the speed can be adjusted according to different requirements, which further facilitates its use.

[0016] 3. The handle is connected to the mixing drum through the upper hoop, which effectively increases the connection force area between the handle and the mixing drum, ensuring that the handle is not easy to loosen, so the structure is more reliable.

[0017] 4. The driving mechanism is fixed at the upper port of the mixing drum, which can achieve synchronous displacement and further facilitate its use and transportation.

[0018] 5. At least one guide block with a guiding bevel is installed at the lower part of the inner cavity wall of the mixing drum. The guiding bevel can make the ink (or color paste) rotating along the inner cavity wall in the mixing drum move toward the center, and the ink (or color paste) originally located in the center is squeezed toward the inner cavity wall. This continuous exchange stirring method effectively increases the uniformity of the ink or color paste stirring.

[0019] The present invention will be further described below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1-Figure 2 It is a structural diagram of the present utility model. DETAILED DESCRIPTION

[0021] like Figure 1-Figure 2 As shown, the energy-saving stirring device for ink production of the present invention comprises a stainless steel stirring drum 1, a drive mechanism 2 mounted on the stirring drum 1, and a stirring head 3 mounted at the bottom end of the output shaft 21 of the drive mechanism 2 and extending into the stirring drum 1. The stirring head 3 is formed by a ratchet with ratchet teeth arranged around its perimeter. A metal upper hoop 4 is fixed to the upper portion of the outer wall of the stirring drum 1. The upper hoop 4 is provided with a handle. The ratchet teeth on the perimeter of the ratchet are curved in the same direction. The ratchet is mated to the bottom end of the output shaft of the drive mechanism via an integral connector and securely locked by a locking screw. A liquid outlet pipe with a control valve is provided at the bottom of the stirring drum 1. The upper hoop 4 is integrally connected to the stirring drum 1 by welding or strong adhesive. The specific arrangement of the handle can be determined according to needs. For example, it can be an annular handle mounted on the upper hoop 4, securely connected to the upper hoop 4 by at least four welded legs. Preferably, the handle comprises a front handle and a rear handle welded to the upper hoop 4, each handle 5 securely connected to the upper hoop 4 by at least two welded legs. Furthermore, the handle 5 preferably comprises a transverse rod 51 and at least two welded legs 52 that securely connect the middle portion of the transverse rod 51 to the upper hoop 4. The left and right ends of the transverse rod extend outward, making it easier for multiple people to grasp and lift the mixer together. To facilitate easy and labor-saving movement of the mixer drum 1, a lower hoop 6 is provided at the bottom end of the outer wall of the mixer drum 1. Multiple universal wheels 7 are connected to the lower hoop 6.

[0022] Furthermore, a support rod 8 is provided at the upper end of the mixing drum 1, and the drive mechanism 2 is fixed on the support rod 8. The drive mechanism 2 includes a drive motor and an external transmission. There are two support rods 8 at the upper end of the mixing drum 1, and they are arranged in parallel to form a support frame. In order to make the power connection line of the drive mechanism well hidden in the storage cylinder when not in use and not easy to fall off, while ensuring the overall appearance is beautiful, a storage cylinder located at the periphery of the drive motor can also be provided on the support frame. The gap between the storage cylinder and the drive motor forms a cavity for the power connection line of the drive motor to be built in and hidden.

[0023] In order to further improve the stirring efficiency, at least one guide block is installed at the lower part of the inner cavity wall of the mixing drum 1, and at least one of the left and right sides of the guide block has a guide bevel to guide the material to the middle of the mixing drum. The guide bevel can make the ink (or color paste) rotating along the inner cavity wall in the mixing drum move closer to the middle direction. The ink (or color paste) originally located in the middle is squeezed toward the inner cavity wall. This continuous exchange stirring method effectively increases the uniformity of the stirring of the ink or color paste. Another advantage is that the utility model can slightly block the guide block to prevent the ink or color paste in the mixing drum from rotating too fast in the same direction, thereby further ensuring the uniformity of the stirring of the ink or color paste.
