DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings of the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0024] In the description of the utility model, it needs to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.

[0025] Please refer to Figure 1 , Figure 6 A kind of dispensing device for label printing ink, its structure is consistent with prior art, including multiple sequentially arranged storage tanks 2, main function is to store base material.

[0026] The right side of each storage tank 2 is provided with a discharge pipe 14 for conveying base material. In actual application, the required printing ink can be prepared by mixing multiple base materials and adding solvent for stirring.

[0027] It is worth noting that the device further includes a base 4, which mainly serves to support the storage tank 2. In addition, the upper end of the right side of the base 4 is provided with a rotatable lead screw 3, and the outer side of the lead screw 3 is connected with a driving block 1 through threads, and the right side of the driving block 1 is fixedly connected with a mixing tank. In actual operation, the base material discharged from the storage tank 2 through the discharge pipe 14 flows into the mixing tank, and then the mixing tank is moved to a suitable position for stirring, and the lead screw 3 serves to adjust the position of the mixing tank to match the position of different storage tanks 2.

[0028] In order to ensure that the lead screw 3 can effectively drive the driving block 1, the device is provided with a limiting rod connected with the base 4 at the lower end of the driving block 1. This design limits the driving block 1 with the limiting rod to ensure that the driving block 1 will not rotate with the lead screw 3.

[0029] In addition, in order to realize the automatic rotation of the lead screw 3, the device is fixedly installed with a driving motor (not shown in the figure, but Figure 1 The enlarged view part in the figure shows the key groove cooperation of the lead screw and the output shaft of the driving motor) on the upper end of the base 4, and the output shaft of the driving motor is connected with the lead screw 3 through a transmission device.

[0030] Please refer to Figure 2 , Figure 3 Compared with the existing technical equipment, the unique feature of the device is that the right side of the discharge pipe 14 is provided with a discharge pipe 16, and the lower end opening of the discharge pipe 16 is in the same vertical plane with the mixing tank. This design ensures that the base material can smoothly and accurately fall into the mixing tank.

[0031] In addition, in order to adjust the flow of the base material into the discharge pipe 16, the device is jointly provided with a baffle plate 15 between the discharge pipe 14 and the discharge pipe 16. The projection height and width of the baffle plate 15 in the vertical direction are greater than the diameter of the inner cavity of the discharge pipe 14, so as to ensure that the device can close the inner cavity channel of the discharge pipe 14 through the baffle plate 15. Only when necessary, the baffle plate 15 can be moved upward to unblock the inner cavity channel of the discharge pipe 14, so that the base material can smoothly enter the discharge pipe 16.

[0032] Specifically, please refer to Figure 5 , the discharge pipe 14 and the discharge pipe 16 are jointly provided with a containing groove 18 near the end, and the upper end of the containing groove 18 is an open structure. By using the existence of the containing groove 18, the ink overflow and waste can be effectively prevented.

[0033] It should be pointed out that in actual operation, by adjusting the distance of the upward movement of the baffle plate 15, the overlapping area of the baffle plate 15 and the inner cavity channel of the discharge pipe 14 in the vertical direction can be accurately controlled. In other words, by adjusting the upward movement distance of the baffle plate 15, the base material discharge rate of the discharge pipe 14 can be effectively controlled, thereby realizing the accurate control of the base material discharge amount per unit time and achieving the technical effect of adjusting the base material discharge amount according to the base material discharge rate.

[0034] Please refer to Figure 2 、 Figure 4 , specifically, in order to realize the upward movement of the baffle plate 15, the device is provided with a fixed plate 9 fixedly connected on the right side of each storage tank 2. The upper end of the fixed plate 9 is fixedly connected with the positioning plate 5, and the lower end is fixedly connected with the limiting ring 11.

[0035] The inner side of the limiting ring 11 is provided with a plug-in driven rod 12, and the lower end of the driven rod 12 is fixedly connected with the baffle plate 15. Under this structure, when the driven rod 12 is constrained by the limiting ring 11 to move up and down linearly, it can drive the baffle plate 15 to perform corresponding up and down movement.

[0036] In order to realize the up and down linear movement of the driven rod 12, the device is provided with a driving mechanism 17 at the lower end of the driven rod 12. The driving mechanism 17 is composed of a follower ring 1701 which is sleeved on the outer side of the driven rod 12 and is in sliding connection with it.

[0037] The lower end of the follower ring 1701 is fixedly connected with an installation plate 1702 on the front and back sides. In a single driving mechanism 17, the lower ends of the two installation plates 1702 are jointly provided with a driving piece 1705, and the driving piece 1705 is in movable connection with the corresponding installation plate 1702.

[0038] By ensuring that the driving block 1 is in the same horizontal plane as the driving member 1705, and the projection of the driving block 1 in the vertical plane presents a trapezoidal structure with the upper end width smaller than the lower end width, when the driving block 1 is driven to move linearly forward and backward by the lead screw 3, the driving block 1 can convert the horizontal direction thrust applied on the driving member 1705 into vertical direction thrust by using the inclined surface of the side end of the driving block 1, so as to realize the upward movement of the driving member 1705, i.e. the driven rod 12.

[0039] Correspondingly, when there is no contact between the driving block 1 and the driving member 1705, and the driving member 1705 does not bear the vertical direction thrust, the gravity of the driven rod 12 and the driving member 1705 itself will promote the downward movement of the driving block 1.

[0040] In actual operation, generally, the driving member 1705 is not in contact with the driving block 1, and the blocking plate 15 is embedded in the accommodating groove 18 to close the inner cavity passage of the discharging pipe 14. However, as the lead screw 3 rotates, the driving block 1 moves to the position in contact with the driving member 1705, at this time, as the driving block 1 continues to move, the driving member 1705 drives the blocking plate 15 to move upward, opens the inner cavity passage of the discharging pipe 14, and the base material flows from the discharging pipe 14 into the discharging pipe 16, and finally flows into the mixing tank.

[0041] Please refer to Figure 2 , Figure 3 , further, in order to ensure that the driven rod 12 can effectively drive the blocking plate 15 to reset downward, the device is coaxially provided with a compression spring I 8 at the upper end of the driven rod 12. The compression spring I 8 provides downward pressure for the driven rod 12, ensuring that the driven rod 12 has sufficient downward reset driving force.

[0042] Specifically, in order to accurately control the upward movement distance of the blocking plate 15, the device is provided with an adjusting plate at the other end of the compression spring I 8, and the upper end of the adjusting plate is fixedly connected with a screw rod I 6. The outer side of the screw rod I 6 is screwed with a positioning nut 7, and the upper end of the positioning nut 7 abuts against the positioning plate 5. By rotating the positioning nut 7, the relative height between the positioning nut 7 and the screw rod I 6 can be adjusted, and thus the initial compression amount of the compression spring I 8 is changed, i.e. the downward pressure applied by the compression spring I 8 on the driven rod 12 under the action of no external force is adjusted.

[0043] In addition, the device is coaxially provided with a compression spring II 13 at the lower end of the driven rod 12, and the other end of the compression spring II 13 abuts against the follower ring 1701 of the driving mechanism 17. When the follower ring 1701 moves upward, the compression spring II 13 will be forced to compress, thereby providing upward thrust for the driven rod 12.

[0044] Therefore, under the condition that the single upward movement distance of the follower ring 1701 is fixed, the device can accurately control the upward movement distance of the blocking plate 15 by adjusting the downward pressure applied by the compression spring I 8 on the driven rod 12 in the initial state.

[0045] Meanwhile, in practical applications, since the upward thrust exerted by the compression spring II13 on the driven rod 12 is affected by its own compression length, and the compression amount of the compression spring II13 is closely related to the movement stroke of the drive block 1, by adjusting the magnitude of the downward pressure exerted by the compression spring I8 on the driven rod 12 in the initial state, the precise control of the time for the baffle plate 15 to release the closure of the inner cavity channel of the discharge pipe 14 can be achieved.

[0046] Please refer to Figure 4 Furthermore, to precisely adjust the upward movement distance of the baffle plate 15 and the time it takes for the baffle plate 15 to release the closure of the inner cavity of the discharge pipe 14, this device specifies that the projection of each drive member 1705 in the vertical direction should be U-shaped. The two vertical portions of each drive member 1705 are located in the same vertical plane as the corresponding two mounting plates 1702, and each of the two vertical portions of each drive member 1705 is fixedly connected to a screw II 1704. Two locking nuts 1703 are screwed onto the outer side of each screw II 1704, clamping and fixing the mounting plates 1702 located in the same vertical plane. In this way, the overall height of the drive mechanism 17 can be adjusted by utilizing the interaction between the screw II 1704 and the locking nuts 1703. Even if the height of the drive block 1 remains constant, the upward movement distance of the follower ring 1701 can be controlled by changing the height of the lower end face of the drive mechanism 17 and the initial contact position between the drive member 1705 and the drive block 1. Therefore, by employing various control methods, precise control can be achieved over the upward movement distance of the baffle plate 15 and the time it takes for the baffle plate 15 to release the closure of the inner cavity of the discharge pipe 14.

[0047] Furthermore, the device specifies that the projection of the driven rod 12 in the vertical direction is T-shaped. Contact rings 10 are fixedly connected to the upper and lower ends of the larger diameter portion of the driven rod 12. Simultaneously, compression springs I 8 and II 13 are embedded inside the contact rings 10. By further specifying that the outer diameter of the contact ring 10 is equal to the inner diameter of the limiting ring 11, the movement trajectory of the driven rod 12 is constrained through the cooperation between the contact ring 10 and the limiting ring 11. Therefore, the presence of the contact ring 10 ensures that the overall height of the device meets the actual operational requirements, thereby guaranteeing the convenience of overall operation.

[0048] In the practical application of this utility model:

[0049] First, the operator needs to adjust the height of the drive mechanism 17 and the initial compression amount of the compression spring I8 corresponding to each storage box 2 in turn according to the proportion of each base material of the required printing ink.

[0050] Next, the corresponding drive motor is started, the lead screw 3 begins to rotate, and the drive block 1 moves linearly from front to back;

[0051] Subsequently, during the continuous movement of the driving block 1, the driving block 1 is in contact with the corresponding driving member 1705, and meanwhile, the mixing tank and the discharge pipe 16 corresponding to the driving member 1705 are located in the same vertical plane, at this stage, the driving member 1705 moves upward;

[0052] Finally, with the rising of the driving member 1705, the closure of the baffle plate 15 to the cavity passage of the discharge pipe 14 is removed, and the base material flows from the discharge pipe 14 into the discharge pipe 16 and then into the mixing tank.

[0053] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
