Description

Technical Field

[0001] This utility model relates to the field of mixing equipment technology, and in particular to a quantitative dispensing device for the production of leather auxiliaries. Background Technology

[0002] Leather auxiliaries are important auxiliary chemicals in the leather processing, and their product quality largely depends on the precise proportions of various raw materials. In the production of leather auxiliaries, multiple raw materials typically need to be added to mixing equipment in specific ratios for thorough mixing. Therefore, the accuracy of the formulation directly affects the performance and quality of the final product.

[0003] Volumetric weighing devices are commonly used in existing quantitative batching systems. They typically involve injecting a certain amount of raw material into a container, and once the desired volume is reached, feeding it into a mixing device for blending. To ensure metering accuracy and batching efficiency, existing technologies often employ containers with fixed volumes. During operation, the raw material is fed into the mixing device all at once once it is full, facilitating periodic operations and ensuring high accuracy in raw material measurement. However, a drawback is that fixed-volume containers are difficult to adapt to different raw material ratios, thus limiting their applicability in quantitative batching applications requiring frequent adjustments to additive ratios. Utility Model Content

[0005] To achieve the above objectives, a quantitative dispensing device for leather auxiliaries production is provided, comprising a mixing chamber, several sets of dispensing mechanisms mounted on the top of the mixing chamber, and a drive assembly connected to the dispensing mechanisms for transmission. The drive assembly is used to drive the dispensing mechanisms to periodically dispense materials. The dispensing mechanisms include:

[0006] The mounting base is fixed to the mixing tank and is interconnected with it;

[0007] A rotating drum, rotatably connected within a mounting base, is used to contain and transport leather auxiliary materials; the drive assembly is connected to the rotating drum via a transmission.

[0008] A capacity adjustment component is provided on the rotating drum, which is used to adjust the single feeding capacity by changing the cavity volume formed by the capacity adjustment component and the rotating drum;

The connecting shaft is rotatably connected to the center of the hollow sleeve.

[0019] An adjusting component is provided outside the hollow sleeve, and the connecting shaft extends out of the hollow sleeve and is fixed to the adjusting component;

[0020] The outer wall of the hollow sleeve is sealed to the inner ring surface of the fixed box. When the upper opening is misaligned with the liquid inlet or liquid outlet, the inner wall of the fixed box forms a seal around the upper opening.

[0053] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0054] Reference Figure 1This utility model discloses a quantitative dispensing device for leather auxiliary production, comprising a mixing tank 1, several dispensing mechanisms mounted on the top of the mixing tank 1, and a drive assembly 6 connected to the dispensing mechanisms for transmission. The drive assembly 6 is used to drive the dispensing mechanisms to periodically dispense materials. The dispensing mechanism includes: a mounting base 2, fixed to the mixing tank 1 and interconnected with it; a rotating drum 3, rotatably connected to the mounting base 2 for containing and conveying leather auxiliary raw materials, the drive assembly 6 being connected to the rotating drum 3 for transmission; a capacity adjustment assembly 4, disposed on the rotating drum 3, for adjusting the single dispensing capacity by changing the cavity volume formed by the capacity adjustment assembly 4 and the rotating drum 3; and a locking member 5, disposed on the rotating drum 3 and movably engaged with the capacity adjustment assembly 4, the locking member 5 being used to lock the capacity adjustment assembly 4. The mounting base 2 includes: a fixed box 21; a liquid inlet end 22 and an air outlet end 23, both fixedly mounted on the top of the fixed box 21; and a liquid outlet at the bottom of the fixed box 21.

[0055] By adopting the above technical solution, during use, the capacity of the rotating drum 3 is adjusted by the capacity adjustment component 4 to ensure that the raw material injected in a single batch reaches the required volume. Then, the capacity adjustment component 4 is locked by the locking component 5 to maintain a constant injection volume, which is the required component of the raw material. In operation, raw material can be injected into the rotating drum 3 through the mounting base 2. After filling, the rotating drum 3 is driven to rotate by the drive component 6, thereby conveying the required volume of raw material to the mixing chamber 1 for mixing. Therefore, by adjusting the capacity adjustment component 4, the volume that can be injected into the rotating drum 3 can be changed, thus adapting to different mixing ratio requirements.

[0056] Reference Figure 3 and Figure 4 The rotating drum 3 includes a hollow sleeve 31 with an upper opening 32 and is rotatably connected to the fixed box 21. A mounting bracket 33 is also fixedly installed on the hollow sleeve 31, and a fixed shaft 34 coaxial with the rotating drum 3 is fixedly installed on the mounting bracket 33. When in use, when the upper opening 32 is at its highest point, raw materials can be injected into the hollow sleeve 31 through an external device connected to the liquid inlet 22. After completion, the hollow sleeve 31 rotates until the upper opening 32 reaches the liquid outlet, and then flows into the mixing box 1 through the liquid outlet. As shown in the figure, the fixed box 21 has an inner ring surface, and a groove is provided on the inner ring surface. That is, the diameter of the inner ring surface in the middle is larger than the diameter of the two end faces. This allows the hollow sleeve 31 to be stably rotated and connected in the fixed box 21. In addition, in order to make its rotation stable, it can be installed by bearing. In order to ensure the sealing effectiveness, a sealing element can also be provided between the inner ring surface of the fixed box 21 and the hollow sleeve 31 to achieve a good sealing effect.

[0057] Reference Figure 3 , Figure 5 as well as Figure 6The capacity adjustment assembly 4 includes: an adjustment plate 41, a connecting shaft 42, and a fixing plate 43 disposed inside the hollow sleeve 31. The end of the adjustment plate 41 is fixed to the connecting shaft 42, and one end of the fixing plate 43 is sleeved on the connecting shaft 42. The fixing plate 43 is also fixed to the hollow sleeve 31. The connecting shaft 42 is rotatably connected to the center of the hollow sleeve 31. An adjustment member 44 is disposed outside the hollow sleeve 31. The connecting shaft 42 extends out of the hollow sleeve 31 and is fixed to the adjustment member 44. The outer wall of the hollow sleeve 31 is sealed to the inner annular surface of the fixed box 21. When the upper opening 32 is misaligned with the liquid inlet 22 or the liquid outlet, the inner wall of the fixed box 21 forms a seal against the upper opening 32.

[0058] Furthermore, an elastic soft membrane 8 is also provided in the cavity, and the elastic soft membrane 8 is fixed to the adjusting plate 41 and the fixing plate 43 to improve the sealing effect.

[0059] Reference Figure 6 and Figure 7 The adjusting component 44 includes a ratchet 441, on which a spiral spring 442 is fixedly mounted. The inner end of the spiral spring 442 is fixed to the fixed shaft 34. The spiral spring 442 provides elastic force to the ratchet 441. When the ratchet 441 rotates (towards the inclined surface of its ratchet teeth), the outer end of the spiral spring 442 is fixed to the ratchet 441. This rotation of the ratchet 441 increases the elastic potential energy of the spiral spring 442, causing the ratchet 441 to tend to reset after it stops rotating. However, because part of the locking component 5 is stuck at the ratchet teeth, it hinders the rotation of the ratchet 441. After the locking component 5 is released from locking the ratchet 441, the spiral spring 442 can drive the ratchet 441 to reset.

[0060] Reference Figure 6 and Figure 7 An indicator rod 45 located on one side of the hollow sleeve 31 is also fixedly installed on the connecting shaft 42. A scale 7 on the hollow sleeve 31 is also provided on the same side as the indicator rod 45. The operator can adjust the scale by moving the indicator rod 45 and can ensure the adjustment is accurate by observing the scale 7.

[0061] Reference Figure 3The locking component 5 includes: a fixing block 51, fixedly mounted on the hollow sleeve 31; a trapezoidal locking block 52, movably engaged with the ratchet teeth of the ratchet wheel 441; a pull rod 53, movably mounted on the fixing block 51, with one end fixed to the trapezoidal locking block 52; and a return spring 54, mounted on the pull rod 53, with both ends fixed to the fixing block 51 and the trapezoidal locking block 52 respectively. When the indicator rod 45 is turned, the ratchet wheel 441 rotates, causing the ratchet teeth to push out the trapezoidal locking block 52. After the angle is adjusted, under the action of the return spring 54, the trapezoidal locking block 52 is pressed back in and engaged with the ratchet teeth, thereby ensuring that the angle remains unchanged, and thus ensuring that the maximum volume of the adjusted receiving cavity remains unchanged. Specifically, the inclined surface of ratchet 441 contacts the trapezoidal inclined surface of trapezoidal block 52. Therefore, when the indicator lever 45 is turned, the ratchet 441 is rotated. At this time, the inclined surface of the ratchet tooth presses against the trapezoidal inclined surface of trapezoidal block 52 until the two inclined surfaces disengage. Then, the ratchet 441 continues to rotate, and the trapezoidal block 52 is engaged between two adjacent ratchet teeth. Under the action of the spiral spring 442, the ratchet teeth will slightly rebound, so that the plane of the ratchet teeth abuts against the trapezoidal inclined surface of trapezoidal block 52, thus completing one angle adjustment. When the operator needs to manually release the locking state, the operator only needs to pull the lever 53 to disengage ratchet 441 from trapezoidal block 52.

[0062] Reference Figure 1 The drive assembly 6 includes: a drive motor 61, whose output shaft is fixedly mounted with a rotating shaft 62, which is also rotatably connected to the mixing box 1; two pulleys 63, which are respectively fixedly mounted on the rotating shaft 62 and the hollow sleeve 31, and the two pulleys 63 are connected by a belt 64. The drive motor 61 is a motor, and the drive motor 61 is controlled by an external control device (such as a PLC controller) to start and stop, so as to realize the periodic rotation of the drum 3. The control logic is as follows: In the initial state, the upper opening 32 of the rotating drum 3 is at its highest point, aligned with the liquid inlet 22, and the raw material is injected into the rotating drum 3 through the liquid inlet 22. After injection, the external control device controls the drive motor 61 to start, driving the rotating drum 3 to rotate 180 degrees through the pulley 63 and belt 64, so that the upper opening 32 rotates to its lowest point and aligns with the liquid outlet at the bottom of the fixed box 21. Under the action of gravity, the raw material is discharged from the liquid outlet into the mixing box 1. After discharge, the external control device controls the drive motor 61 to start again, driving the rotating drum 3 to continue rotating 180 degrees, so that the upper opening 32 returns to its highest point, waiting for the next feeding. This cycle is repeated to achieve periodic feeding.

[0063] Working principle: When adjusting the maximum volume, the operator rotates the capacity adjustment component 4 to make the maximum volume inside the rotating drum 3 reach the required value, and locks the capacity adjustment component 4 with the locking component 5. When dispensing, the raw materials are injected into the rotating drum 3 through the mounting base 2, and the rotating drum 3 is driven to rotate by the drive component 6 to input the raw materials into the mixing box 1 for mixing.

[0064] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
