TECHNICAL FIELD

[0001] The utility model relates to the technical field of coating machine, specifically, relates to a paste hopper and coating machine. BACKGROUND

[0002] With the wide application of lead-acid storage batteries in many fields such as automobiles, communications and electric power, higher requirements are put forward for the production efficiency and quality of the plates. As a key equipment in the production process of the plates, the coating machine is becoming increasingly important, prompting the continuous development and improvement of related technologies to meet the demand for large-scale, high-efficiency production of high-quality lead-acid storage battery plates

[0003] Early paste coating of the plates was mostly operated manually. This method not only has low efficiency and cannot meet the demand for large-scale production, but also cannot guarantee the uniformity and consistency of the paste coating, resulting in uneven quality of the plates and affecting the performance and service life of the batteries.

[0004] Later, some simple mechanical plate coating devices appeared, such as coating machines, but these devices still have many deficiencies in function and performance, such as the inability to adjust the paste pressure simply and quickly. SUMMARY

[0005] The utility model provides a paste hopper and coating machine, solve the problem that in related art cannot simple and quick adjustment paste pressure.

[0006] The technical scheme of the utility model is as follows:

[0007] A paste hopper, comprising a shell and a paste coating roller rotatably arranged in the shell, further comprising,

[0008] An eccentric roller is rotatably arranged in the shell, and the rotational axis is parallel to the rotational axis of the paste coating roller, and the eccentric roller is located above one side of the paste coating roller.

[0009] A gap adjusting rod is rotatably arranged in the shell, and the rotational axis is parallel to the rotational axis of the paste coating roller, and the gap adjusting rod is located between the eccentric roller and the paste coating roller, and the gap adjusting rod is used for abutting against the eccentric roller after rotation.

[0010] As a further technical scheme, the cross section of the gap adjusting rod is semicircular or arc-shaped.

[0011] As a further technical scheme, further comprising,

[0012] An adjusting tooth is arranged on the eccentric roller and located outside the paste hopper.

[0013] An adjusting plate handle is rotatably arranged on the outer wall of the paste hopper and has a tooth part, and the tooth part is engaged with the adjusting tooth.

[0014] As a further technical solution, further comprising,

[0015] Lowering the paste roller wheel is rotatably arranged in the paste hopper, located above the paste roller wheel, one side of the eccentric roller wheel.

[0016] As a further technical solution, further comprising,

[0017] Stirring fins are rotatably arranged in the paste hopper, and there are several above the paste roller wheel.

[0018] As a further technical solution, a coating machine is also proposed, comprising the paste hopper, further comprising,

[0019] Frame;

[0020] The overturning shaft is rotatably arranged on the frame, and the rotation axis is parallel to the rotation axis of the paste roller wheel.

[0021] The support plate is arranged on the overturning shaft, and the paste hopper is arranged in a lifting manner relative to the support plate.

[0022] As a further technical solution, further comprising,

[0023] The rear support is arranged on the paste hopper.

[0024] Linear drive one is arranged on the support plate and is in driving connection with the rear support.

[0025] As a further technical solution, further comprising,

[0026] The front support is arranged on the paste hopper.

[0027] Linear drive two is arranged on the frame, and the output end of the linear drive two is hinged or abuts on the front support.

[0028] The working principle and beneficial effects of the utility model are as follows:

[0029] In the utility model, the eccentric roller wheel and the gap adjusting rod are arranged on one side of the paste roller wheel in the paste hopper, the gap between the two and the paste roller wheel is adjusted, and then the paste pressure is changed, so as to meet the actual production and processing requirements.

[0030] Specifically, in the working process of the coater, the stability of the lower paste pressure is crucial for uniform paste coating. Through the specific installation position of the eccentric roller and the eccentricity of the eccentric roller itself, the relative distance, i.e. the gap, between the eccentric roller and the paste roller changes during the rotation of the eccentric roller. The increase or decrease of the gap will cause the pressure of the paste roller to decrease or increase. After the adjustment rod rotates and tightly abuts the eccentric roller, the gap change caused by the eccentric wheel can be fine-tuned. For example, in some cases where the coating precision is very high, the lower paste pressure needs to be controlled within a very narrow range. Relying solely on the eccentric wheel may cause the gap to change too much or too little. The adjustment rod can accurately control the amplitude of the gap change through its own adjustment, making the adjustment of the lower paste pressure more precise. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0036] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the specific implementation modes of the present application will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative labor, and other embodiments can also be obtained.

[0037] For the sake of simplicity of the drawings, only the parts related to the utility model are shown in the drawings, which do not represent the actual structure of the product. In addition, in order to make the drawings simple and easy to understand, in some drawings, only one of the parts with the same structure or function is shown schematically, or only one of them is marked. In this text, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0038] In this text, it should be noted that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication of two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0039] In addition, in the description of the present application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.

[0040] As Figure 1 shown, a paste hopper is proposed, which comprises a shell 1 and a coating roller 2 rotatably arranged in the shell 1, further comprising,

[0041] An eccentric roller 3 is rotatably arranged in the shell 1, and the rotation axis is parallel to the rotation axis of the coating roller 2. The eccentric roller 3 is located above the side of the coating roller 2.

[0042] A gap adjusting rod 4 is rotatably arranged in the shell 1, and the rotation axis is parallel to the rotation axis of the coating roller 2. The gap adjusting rod 4 is located between the eccentric roller 3 and the coating roller 2, and the gap adjusting rod 4 is used to abut the eccentric roller 3 after rotation.

[0043] In the embodiment, in order to solve the problem that the existing technology cannot adjust the paste pressure simply and quickly, the eccentric roller 3 and the gap adjusting rod 4 are arranged on one side of the coating roller 2 in the paste hopper, and the gap between the two and the coating roller 2 is adjusted, so as to change the paste pressure and meet the actual production and processing requirements.

[0044] Specifically, in the working process of the coater, the stability of the lower paste pressure is crucial for uniform paste coating. Through the specific installation position of the eccentric roller 3 and its eccentric characteristics, the eccentric roller 3 changes the relative distance, i.e. the gap, between the paste coating roller 2 during rotation. The increase or decrease of the gap will cause the paste coating roller 2 to change the pressure on the paste. After the rotation of the gap adjusting rod 4, which is in close contact with the eccentric roller 3, the gap change caused by the eccentric roller can be fine-tuned. For example, in some cases where the coating precision is very high, the lower paste pressure needs to be controlled within a very narrow range. Relying solely on the eccentric roller may cause the gap to change too much or too little. After the eccentric roller 3 determines the general paste distribution and gap range, the gap adjusting rod 4 can change the distance between the two in a small range, effectively making up for the lack of precision when adjusting the eccentric roller 3, and making the adjustment of the lower paste pressure more accurate.

[0045] Further, the cross section of the gap adjusting rod 4 is semicircular or arc-shaped.

[0046] In this embodiment, the semicircular or arc-shaped cross section can be in close contact with the eccentric roller 3. The semicircular arc can fit the circumference of the eccentric roller 3, and the contact between the two is smooth during the rotation of the eccentric roller 3. Just like a semicircular groove cooperating with a circular shaft, the contact position can be flexibly changed after the rotation of the eccentric roller 3, and a certain degree of tightness can be ensured.

[0047] In addition, the cross section of the gap adjusting rod 4 can also be a circular shape with an arc-shaped notch. When the gap adjusting rod 4 is rotated, the arc-shaped notch part can also be in close contact with the eccentric roller 3 due to the near point and far point. The cross section of the gap adjusting rod 4 can also be circular, which is set to rotate eccentrically and can also be in close contact with the eccentric roller 3 after rotation.

[0048] Further, it further comprises an adjusting tooth 5, which is arranged on the eccentric roller 3 and located outside the paste hopper 6; an adjusting plate handle 7 is arranged on the outer wall of the paste hopper 6 and has a tooth part 8, which is engaged with the adjusting tooth 5.

[0049] In this embodiment, the adjusting tooth 5 is installed on the eccentric roller 3 and located outside the paste hopper for easy operation. The adjusting plate handle 7 is installed on the outer wall of the paste hopper through a rotating shaft, and the tooth part 8 is engaged with the adjusting tooth 5 on the eccentric roller 3. The length of the adjusting plate handle 7 can be designed to be convenient for hand holding and operation, such as 150 millimeters. The modulus and number of teeth of the tooth part 8 are determined according to the required adjustment accuracy and torque transmission requirements.

[0050] By rotating the adjusting plate 7, the eccentric roller 3 can be conveniently driven to rotate through the meshing transmission of the tooth part 8 and the adjusting tooth 5. This structure enables the operator to easily adjust the position of the eccentric roller 3 outside the paste hopper, thereby changing the gap, without the need to open the paste hopper or use complex tools, improving the convenience and work efficiency of the paste hopper adjustment, and enabling real-time adjustment during the operation of the equipment according to the paste coating effect.

[0051] Further, the paste hopper 6 further comprises a lower paste roller 9, which is rotatably arranged in the paste hopper 6 and located above the paste coating roller 2 and on one side of the eccentric roller 3.

[0052] In this embodiment, the lower paste roller 9 is installed in the paste hopper and located above the paste coating roller 2 and on one side of the eccentric roller 3. The diameter of the lower paste roller 9 can be designed according to the space in the paste hopper and the flowability of the paste, such as 40 mm, and the surface thereof can be made of a material with a certain roughness or special texture to better grasp and transfer the paste. The lower paste roller 9 and the paste coating roller 2 maintain a certain gap, which can be adjusted according to the viscosity of the paste and the required paste coating thickness, such as 2-5 mm.

[0053] The lower paste roller 9 can assist in the supply and distribution of the paste. It can more evenly transport the paste in the paste hopper to the paste coating roller 2, especially for paste with high viscosity, the rotation of the lower paste roller 9 can break the agglomeration state of the paste, so that it is smoothly transferred to the surface of the paste coating roller 2, and through the relative movement with the paste coating roller 2, the paste is further flattened on the paste coating roller 2, improving the uniformity and stability of the paste coating, and reducing defects and fluctuations in the paste coating process.

[0054] Further, the paste hopper 6 further comprises stirring fins 10, which are rotatably arranged in the paste hopper 6 and located above the paste coating roller 2.

[0055] In this embodiment, a plurality of stirring fins 10 are installed in the paste hopper and located above the paste coating roller 2. The stirring fins 10 can be made of metal material and designed as curved blade shape, such as 80 mm in length and 20 mm in width. The installation angle of the stirring fins 10 can be determined according to the stirring requirements of the paste, so that they can fully stir the paste in the paste hopper when rotating. The stirring fins 10 are connected to a driving device, such as a small motor or linked with other rollers such as the paste coating roller 2 through gear transmission.

[0056] The stirring wing 10 can prevent the paste from depositing and caking in the paste hopper. During the operation of the paste hopper, the stirring wing 10 continuously rotates to stir the paste, so that the paste maintains uniform composition and fluidity. This is particularly important for the paste containing solid particles or prone to stratification, which can ensure the consistency of the quality and performance of the paste each time the paste is applied, improve the quality stability of the applied product, and prolong the storage time of the paste in the paste hopper, thereby reducing the problems caused by the deterioration or unevenness of the paste.

[0057] Further, as shown in Figure 2 、 3 , a coating machine is also provided, which comprises a paste hopper and a rack 11, a large overturning shaft 12 is rotatably arranged on the rack 11, and the rotation axis of the large overturning shaft 12 is parallel to the rotation axis of the paste roller 2; a supporting plate 13 is arranged on the large overturning shaft 12, and the paste hopper 6 is arranged in a lifting manner relative to the supporting plate 13.

[0058] In this embodiment, the rack 11 is arranged in the coating machine as a supporting structure of the entire device. The large overturning shaft 12 is mounted on the rack 11 through bearings, and the supporting plate 13 is fixedly mounted on the large overturning shaft 12. The supporting plate 13 can be made of a metal plate and has sufficient strength and rigidity.

[0059] The rack 11 provides a stable mounting basis for other components of the coating machine and ensures the overall stability of the device during operation. The large overturning shaft 12 can drive the supporting plate 13 and the paste hopper to perform an overturning action, which facilitates the switching of the paste hopper between different working states, such as the working position during paste application and the non-working position during cleaning and maintenance. The lifting arrangement of the paste hopper relative to the supporting plate 13 can adapt to the paste application requirements of different thicknesses of plates. By adjusting the height of the paste hopper, the paste roller 2 and the plate surface can maintain appropriate contact pressure and clearance, which improves the precision and quality of paste application and facilitates the installation and disassembly of the paste hopper.

[0060] Further, a rear support 14 is arranged on the paste hopper 6, and a linear driving member 15 is arranged on the supporting plate 13 and is drivingly connected with the rear support 14.

[0061] In this embodiment, the rear support 14 cooperates with the linear driving member 15 to realize the lifting control of the paste hopper. The extension and retraction of the linear driving member 15 drives the rear support 14 to move up and down, thereby changing the height position of the rear end of the paste hopper. The linear driving member 15 can be an electric push rod, an air cylinder, etc. By adjusting the height of the paste hopper, the thickness of the applied paste is adjusted to meet different processing requirements.

[0062] Further, a front support 16 is arranged on the paste hopper 6, and a linear driving member 17 is arranged on the rack 11, and the output end of the linear driving member 17 is hingedly connected or abuts against the front support 16.

[0063] In this embodiment, the linear drive member two 17 can be an electric push rod, a pneumatic cylinder, etc., connected or abutted on the front support 16, used to stabilize the hopper. For example, when the hopper is turned over or lifted, the linear drive member two 17 will act accordingly to give the hopper a supporting force, making it more stable during movement.

[0064] As shown in Figure 2 The rotating drum 18 is also provided on the frame 11, which provides a stable support plane for the coated plate. During the coating process, the plate needs a flat support. The surface of the rotating drum 18 can make the plate stable, ensuring that the plate will not deform or shift during subsequent coating operations. For example, when the plate enters the coating machine through the conveying device and reaches the surface of the rotating drum 18, the rotating drum 18 acts like a solid "workbench", creating good conditions for plate coating.

[0065] In addition, the rotating drum 18 can move the plate. It is driven by a motor or other power device to rotate at a certain speed. When the plate is placed on the rotating drum 18, the plate will be transmitted forward due to the rotation of the rotating drum 18. This transmission method ensures the continuity of the coating process, so that the plate can pass through different stations such as coating area and drying area according to the set speed and path. For example, in a continuous production coating line, the uniform rotation of the rotating drum 18 can ensure that each plate can complete the coating process in an orderly manner, improving production efficiency.

Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
