Description

Technical Field

[0001] This utility model relates to the technical field of thin film production equipment, and in particular to a controllable height adjustment mechanism for film drying. Background Technology

[0002] In the production of films (such as specialty industrial films and packaging films), the coated wet film needs to be dried to solidify the slurry on its surface. Hanging drying is a commonly used process, and its core requirement is the ability to precisely adjust the distance between the drying equipment and the film surface based on the film material, slurry characteristics, and production speed. The accuracy of this distance directly affects drying efficiency, energy consumption, and the quality of the final product.

[0003] Existing hoisting mechanisms for drying equipment often have the following shortcomings: Insufficient rigidity and stability: Traditional frame structures are prone to deformation or vibration when hoisting heavy drying equipment and frequently raising and lowering it, which changes the parallelism between the drying equipment and the film surface and affects the uniformity of drying.

[0004] Complex installation and poor adaptability: Most mechanisms are welded together, resulting in a large workload for on-site installation and difficulty in adjustment once completed. The existing mechanisms are ill-suited for changes in production line layout or the need to replace drying equipment of different sizes.

[0005] Stress concentration at connection points: The connection points between the lifting mechanism and the frame and top frame are usually simple bolt connections. Under long-term load and operation, these connection points are prone to fatigue damage, which poses a safety hazard.

[0006] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a controllable height adjustment mechanism for film drying, making it more valuable for industrial applications. Utility Model Content

[0007] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a controllable height adjustment mechanism for film drying.

[0008] To achieve the above objectives, the present invention adopts the following technical solution: A controllable height adjustment mechanism for film drying includes a frame, a top frame mounted on top of the frame, and a baking equipment mounting frame mounted below the top frame for mounting baking equipment. At least two synchronous lifting mechanisms are installed at the bottom of the top frame. The top of the synchronous lifting mechanism is connected to the top frame through an upper mounting assembly, and the telescopic part at the bottom of the synchronous lifting mechanism is connected to the baking equipment mounting rack below. The upper mounting assembly includes a lifting mechanism mounting frame, an upper mounting plate, and a reinforcing mounting plate. The top of the synchronous lifting mechanism is mounted on the bottom of the lifting mechanism mounting frame, and the lifting mechanism mounting frame is mounted on the bottom of the upper mounting plate. Reinforcing mounting plates are mounted on both the left and right sides of the top of the upper mounting plate. Several upper reinforcing ribs are evenly arranged on the reinforcing mounting plate along the front-back direction. Two upper reinforcing ribs on the left and right sides, which correspond to each other, pass through the frame and are then connected together. The top of the rack is mounted to the top frame above by several side mounting assemblies. The side mounting assemblies include two side mounting plates mounted together from top to bottom. Several side reinforcing ribs are provided on the top outer side of the upper side mounting plate and several side reinforcing ribs are provided on the bottom outer side of the lower side mounting plate. The two side reinforcing ribs on the left and right sides or front and back sides, which correspond one-to-one, pass through the rack or top frame and are then connected together.

[0009] As a further improvement of this utility model, reinforcing support rods are installed around the top frame and the frame, so that the frame, the top frame and the reinforcing support rods form a triangular support structure.

[0010] As a further improvement of this utility model, a drop rack for supporting the product is installed at the bottom near the frame.

[0011] As a further improvement of this utility model, several support feet are installed at the bottom of the frame, and counterweights are installed inside the support feet.

[0012] As a further improvement of this utility model, the synchronous lifting mechanism includes a motor, electric push rods and a synchronizer, wherein the motor drives multiple electric push rods to extend and retract synchronously through the synchronizer.

[0013] As a further improvement of this utility model, the synchronizer is a mechanical linkage shaft, which is connected to the input shaft of each electric push rod through a bevel gear box.

[0014] As a further improvement of this utility model, the bevel gearbox is a retractable universal coupling structure.

[0015] As a further improvement of this utility model, the telescopic part at the bottom of the synchronous lifting mechanism is connected to the baking equipment mounting bracket below via a universal joint.

[0016] As a further improvement of this utility model, multiple sets of quick clamping mechanisms for clamping the baking equipment are provided on the baking equipment mounting rack.

[0017] By means of the above solution, this utility model has at least the following advantages: This invention constructs a statically indeterminate and stable frame through multiple reinforcement designs including an upper mounting component, a side mounting component, and a triangular reinforcing support rod. This effectively suppresses deformation and vibration generated during hoisting and lifting, providing a stable physical basis for the drying process and greatly improving structural rigidity and stability.

[0018] The upper mounting component of this invention cleverly distributes the concentrated load to the top of the frame, while the side mounting component ensures the robustness of the main frame nodes, fundamentally solving the problem of stress concentration at the connection points and guaranteeing the service life and safety of the equipment.

[0019] This utility model uses a bevel gearbox with a universal coupling and a universal joint connection, which gives the transmission system and the actuator a certain tolerance capability, ensuring that the entire lifting system can operate smoothly and synchronously even in the presence of minor installation errors, thus reducing maintenance requirements.

Detailed Implementation

[0025] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0026] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] The first embodiment of this utility model: like Figures 1-3 As shown, a controllable height adjustment mechanism for film drying in this embodiment includes a frame 1, a top frame 2 installed on the top of the frame 1, and a baking equipment mounting frame 7 installed below the top frame 2 for mounting baking equipment.

[0028] At least two synchronous lifting mechanisms 3 are installed at the bottom of the top frame 2. The top of the synchronous lifting mechanism 3 is connected to the top frame 2 through the upper mounting assembly 4, and the telescopic part at the bottom of the synchronous lifting mechanism 3 is connected to the baking equipment mounting rack 7 below.

[0029] The upper mounting assembly 4 includes a lifting mechanism mounting frame 41, an upper mounting plate 42, and a reinforcing mounting plate 43. The top of the synchronous lifting mechanism 3 is mounted on the bottom of the lifting mechanism mounting frame 41, and the lifting mechanism mounting frame 41 is mounted on the bottom of the upper mounting plate 42. Reinforcing mounting plates 43 are mounted on both the left and right sides of the top of the upper mounting plate 42. Several upper reinforcing ribs 44 are evenly arranged on the reinforcing mounting plate 43 along the front-back direction. Two upper reinforcing ribs 44 on the left and right sides, which correspond to each other, pass through the frame 1 and are then connected together.

[0030] These upper reinforcing ribs pass through the top crossbeam of the frame, and then the corresponding ribs on the left and right sides are connected together. This design effectively disperses and transfers the huge load generated by the lifting mechanism to the entire top of the frame through the upper mounting plate, the reinforcing mounting plate, and the upper reinforcing ribs, greatly enhancing the local strength and rigidity of the top frame load-bearing area and avoiding stress concentration.

[0031] The top of the frame 1 is mounted to the top frame 2 via several side mounting assemblies 5. Each side mounting assembly 5, from top to bottom, comprises two side mounting plates 51 mounted together. Several side reinforcing ribs 52 are provided on the top outer side of the upper side mounting plate 51, and several side reinforcing ribs 52 are provided on the bottom outer side of the lower side mounting plate 51. Two corresponding side reinforcing ribs 52 on the left and right sides or front and back sides pass through the frame 1 or top frame 2 and are then connected together. This double-connection structure forms a robust frame node, ensuring the stability of the connection between the frame and the top frame and effectively resisting lateral forces.

[0032] Reinforcing support rods 6 are installed around the perimeter between the top frame 2 and the frame 1, forming a triangular support structure with the frame 1, top frame 2, and reinforcing support rods 6. This further strengthens the frame structure, significantly improving the overall rigidity and stability of the entire equipment during load-bearing and operation.

[0033] A drop rack 9 for supporting the product 8 is installed near the bottom of the frame 1.

[0034] Several support legs 10 are installed at the bottom of the frame 1, and counterweights are installed inside the support legs 10.

[0035] The synchronous lifting mechanism 3 includes a motor, electric push rods, and a synchronizer. The motor drives multiple electric push rods to extend and retract synchronously via the synchronizer. The synchronizer is a mechanical linkage shaft, which is connected to the input shaft of each electric push rod via a bevel gear box. The bevel gear box is a telescopic universal coupling structure. The telescopic part at the bottom of the synchronous lifting mechanism 3 is connected to the baking equipment mounting bracket 7 below via a universal joint.

[0036] The synchronizer in the synchronous lifting mechanism uses a bevel gearbox with a telescopic universal coupling structure. This allows for slight positional and angular deviations in each electric push rod during installation, avoiding assembly stress and wear caused by rigid connections, and ensuring the smoothness and reliability of synchronous transmission. Simultaneously, the telescopic part connects to the baking equipment mounting frame via a universal joint, compensating for minor asynchrony among the multiple push rods during movement and preventing internal stress in the equipment frame.

[0037] The baking equipment mounting rack 7 is equipped with multiple sets of quick clamping mechanisms for clamping the baking equipment. These quick clamping mechanisms may include snap-fit ​​and rotary handles to enable quick installation and removal of the baking equipment.

[0038] The second embodiment of this utility model: like Figure 1As shown, the controllable height adjustment mechanism for film drying in this embodiment consists of a robust frame 1 and a top frame 2 fixed to its top by a side mounting assembly 5. The bottom of the frame 1 is provided with support feet 10 with counterweights to increase overall stability. A drop rack 9 is also installed at the bottom of the frame 1 to provide transition support for the product 8 (i.e., the film) running below.

[0039] Further description of the core connection structure: like Figure 2 The upper mounting assembly 4 is a key component supporting the synchronous lifting mechanism 3. The lifting mechanism mounting frame 41 is a U-shaped bracket used to support the motor and housing of the synchronous lifting mechanism 3. The upper mounting plate 42 is a thick steel plate, welded or fixed to the bottom of the lifting mechanism mounting frame 41 with high-strength bolts. Two reinforcing mounting plates 43 are vertically welded to the top left and right sides of the upper mounting plate 42. On each reinforcing mounting plate 43, multiple (e.g., 3-4) upper reinforcing ribs 44 are welded along its length (front and back). During installation, these upper reinforcing ribs 44 pass through pre-drilled holes in the crossbeam at the top of the frame 1, and then nuts are used to lock the ends of the corresponding upper reinforcing ribs 44 on the left and right sides together. This clamping connection efficiently transfers the load of the lifting mechanism to the top main structure of the frame 1.

[0040] like Figure 3 The side mounting assembly 5 is used to connect the uprights of the frame 1 to the side beams of the top frame 2. It is formed by bolting together two side mounting plates 51. The upper side mounting plate 51 has upward-extending side reinforcing ribs 52 welded to its top outer side. These ribs pass through the side beams of the top frame 2 and are locked with corresponding ribs on the other side using nuts. The lower side mounting plate 51 has downward-extending side reinforcing ribs 52 welded to its bottom outer side. These ribs pass through the uprights of the frame 1 and are similarly locked with corresponding ribs on the other side. This design makes the connection point between the frame 1 and the top frame 2 a high-rigidity node.

[0041] like Figure 1 At least two (usually four for balance) synchronous lifting mechanisms 3 are suspended below the top frame 2 via the aforementioned upper mounting assembly 4. Each synchronous lifting mechanism 3 includes a motor, an electric actuator, and a synchronizer. The synchronizer uses a mechanical linkage shaft and is connected to the input shaft of each electric actuator via a bevel gearbox with a retractable universal coupling structure, which gives the transmission system a certain degree of flexibility. The telescopic part at the bottom of the electric actuator is connected to the baking equipment mounting bracket 7 via a universal joint. The baking equipment mounting bracket 7 is equipped with multiple sets of quick-clamping mechanisms 71 for quickly fixing and releasing the baking equipment.

[0042] In addition, at each corner of the frame 1 and the top frame 2, there are diagonally installed reinforcing support rods 6, forming a sturdy triangular structure that greatly enhances the frame's torsional resistance.

[0043] The working process of this embodiment: Initial state: The equipment is installed in place, and the baking equipment is fixed on the baking equipment mounting rack 7 by the quick clamping mechanism and is in a high initial position.

[0044] Height Adjustment: The operator starts the motor of the synchronous lifting mechanism 3 through the control system. The motor drives all electric push rods to retract or extend synchronously through a synchronous transmission system consisting of a bevel gear box and a linkage shaft. Because the transmission chain has a universal coupling and the bottom of the push rod is connected to the baking equipment mounting bracket 7 through a universal joint, the entire lifting process is smooth and without jamming.

[0045] Precise positioning and locking: When the baking equipment reaches the required height, the motor stops. The self-locking function built into the electric push rod ensures it remains reliably in that position. During this process, the entire mechanism is protected by the upper mounting assembly 4, the side mounting assembly 5, and the reinforcing support rod 6, ensuring no visible shaking or deformation.

[0046] Process adaptation and maintenance: When it is necessary to replace or maintain the baking equipment, the quick-clamping mechanism can be released for operation. The entire top frame 2 and lifting system can be separated from the frame 1 by disassembling the side mounting assembly 5, which facilitates the maintenance and replacement of large components.

Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0048] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
