Description

Technical Field

[0001] This utility model particularly relates to a film drying rack. Background Technology

[0002] In film manufacturing, printing, coating, and drying processes, drying racks are commonly used to support multiple take-up rollers with film wound on them for centralized drying or cooling in a suspended state. To maximize space utilization and improve production efficiency, existing drying racks typically employ a layout where multiple take-up rollers are densely arranged. This type of drying rack presents the following problems: the film on adjacent take-up rollers is highly susceptible to collision because the force applied when pushing or removing the rollers into or out of the drying area is difficult to control accurately, leading to collisions between films on adjacent rollers. Secondly, during equipment operation, even slight vibrations from the ground or personnel movement can be transmitted to the drying rack, causing minor wobbling of the take-up rollers. These film collisions can range from minor issues like wrinkles and scratches on the film surface, affecting product appearance quality, to more serious issues like film perforation and breakage, resulting in material waste and production interruptions. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, the present invention proposes a film drying rack.

[0004] To solve the aforementioned technical problems, this utility model adopts the following technical solution: A film drying rack includes a base frame and multiple winding rollers for winding film. Each winding roller has a sliding assembly detachably connected to both ends. The base frame has symmetrically arranged fixed plates along its length, and each fixed plate has a groove. The sliding assemblies slide in conjunction with the grooves, allowing the winding rollers to reciprocate along the grooves. Of two adjacent sliding assemblies located within the same groove, one has a mounting shell containing a fixed post. An elastic element is fitted onto the fixed post, and one end of the elastic element is connected to a sliding abutment platform that slides along the mounting shell. The other sliding assembly has a buffer platform. When the two sliding assemblies approach each other, the buffer platform pushes against the abutment platform, compressing the elastic element to buffer and prevent the films on the two winding rollers from colliding.

[0005] Preferably, at least one end of the slide is provided with a detachable baffle; when the baffle is installed on the fixed plate, it is used to restrict the sliding assembly from sliding out; when the baffle is removed from the fixed plate, it forms an loading and unloading opening for the sliding assembly to enter and exit the slide.

[0006] Preferably, the sliding assembly includes a base that slides in conjunction with the groove; the base is provided with an arc-shaped receiving platform, and the end of the take-up roller is detachably mounted on the arc-shaped receiving platform.

[0007] Preferably, two limiting rings are provided at intervals on the take-up roller, and the two limiting rings are respectively arranged near the two ends of the take-up roller to limit the axial position of the film from both sides.

[0008] Preferably, the elastic element is a spring.

[0009] Preferably, the bottom of the base frame is provided with casters.

[0010] Preferably, two guide rods are also fixed on the mounting shell, and the abutment platform is provided with through holes for the guide rods to pass through.

[0011] The beneficial effects of this utility model are: This invention utilizes a buffer assembly and a buffer platform, each consisting of a mounting shell, a fixed post, an elastic element, and a contact platform, installed on two adjacent sliding components within the same chute. When the sliding components are driven closer together by external force, the buffer platform contacts the contact platform and compresses the elastic element. This process directly converts the kinetic energy of the sliding components into elastic potential energy, which is absorbed and released through the deformation of the elastic element. This mechanism achieves automatic buffering and stopping at the physical level without external intervention, effectively preventing rigid collisions of the winding rollers caused by operational impacts or equipment vibrations, thereby avoiding damage to the film material.

[0018] A film drying rack includes a base frame 1 and multiple winding rollers 2 for winding film. Each winding roller 2 has a sliding assembly 3 detachably connected to both ends. The base frame 1 has a fixed plate 4 symmetrically arranged along its length. The fixed plate 4 has a groove 41, and the sliding assembly 3 slides along the groove 41 to allow the winding roller 2 to reciprocate along the groove 41. Of two adjacent sliding assemblies 3 located within the same groove 41, one has a mounting shell 5. The mounting shell 5 has a fixed post 51, and an elastic element 52 is sleeved on the fixed post 51. One end of the elastic element 52 is connected to an abutment platform 53 that can slide along the mounting shell 5. The other sliding assembly 3 has a buffer platform 530. When the two sliding assemblies 3 approach each other, the buffer platform 530 pushes against the abutment platform 53, compressing the elastic element 52 to buffer and prevent the films on the two winding rollers 2 from colliding.

[0019] Furthermore, at least one end of the slide groove 41 is provided with a detachable baffle 411; when the baffle 411 is installed on the fixed plate 4, it is used to restrict the sliding component 3 from sliding out; when the baffle 411 is removed from the fixed plate 4, it forms an loading and unloading opening for the sliding component 3 to enter and exit the slide groove 41.

[0020] Furthermore, the sliding assembly 3 includes a base 31, which is slidably engaged with the slide groove 41; an arc-shaped receiving platform 32 is provided on the base 31, and the end of the take-up roller 2 is detachably mounted on the arc-shaped receiving platform 32.

[0021] Furthermore, two limiting rings 21 are provided at intervals on the take-up roller 2. The two limiting rings 21 are respectively arranged near the two ends of the take-up roller 2 to limit the axial position of the film from both sides.

[0022] Furthermore, the elastic element 52 is a spring.

[0023] Furthermore, the bottom of the base frame 1 is provided with casters 6.

[0024] Furthermore, two guide rods 510 are fixed on the mounting shell 5, and the abutment platform 53 is provided with through holes 531 for the guide rods 510 to pass through.

[0025] The working principle of this utility model is as follows: See Figure 1 The film drying rack in this embodiment includes a rectangular base frame 1, which is welded from structural steel. Two fixing plates 4 are symmetrically fixed on both sides of the base frame 1 along its length. Each fixing plate 4 has a long, narrow groove 41. Figure 1 We can see multiple take-up rollers 2 arranged in parallel, with each take-up roller 2 connected at both ends to a sliding assembly 3. The sliding assembly 3 is slidably engaged with a groove 41 on the fixed plate 4, and the sliding assembly 3 can only move linearly along the groove 41. Figure 1 Taking a sliding configuration with four take-up rollers 2 as an example, since the film wound on the take-up rollers 2 usually needs to undergo drying operations, the film surface is not dry at this time. That is to say, if two films collide or come into contact during the drying process, it will affect the quality of the film. Therefore, this application improves the anti-collision problem, and the specific implementation principle is as follows: Taking the sliding components 3 connected to two adjacent take-up rollers 2 in the same chute 41 as an example, a mounting shell 5 can be fixedly connected to one of the sliding components 3 by bolts. The mounting shell 5 has an inwardly recessed mounting groove 1-1. A fixing post 51 is fixedly installed in the mounting groove 1-1. An elastic element 52 is sleeved on the fixing post 51. One end of the elastic element 52 is connected to the bottom of the mounting groove 1-1, and the other end is connected to the abutment platform 53. Two guide rods 510 are also fixed on the mounting shell 5. They pass through the corresponding through holes 531 on the abutment platform 53 to ensure that the abutment platform 53 can only slide smoothly in a straight line and will not deflect.

[0026] The application scenario is as follows: When the operator places the take-up roller 2 to be dried onto the base frame 1, or when the take-up roller 2 moves closer to another take-up roller 2 due to external force, one of the sliding components 3 will move towards the other sliding component 3. As the sliding component 3 continues to move within the slide groove 41, the buffer platform 530 first contacts the abutment platform 53 (or the abutment platform 53 contacts the buffer platform 530). As it continues to move forward, the buffer platform 530 pushes the abutment platform 53 to slide into the mounting housing 5, thereby strongly compressing the spring. The compressed spring generates a counterforce, which acts on the two sliding components 3 through the abutment platform 53 and the buffer platform 530, manifesting as a resistance that effectively reduces and ultimately prevents the collision between the two. At this time, a safe gap is still maintained between the films on the two take-up rollers 2. As an embodiment 1, the above-mentioned elastic element 52 can be implemented using a spring.

[0027] Based on the above technical solution, in order to remove the dried film from the base frame 1, this application detachably installs baffles 411 at both ends of each slide 41 using several screws 1-2. Under normal operating conditions, the baffles 411 are secured by the screws 1-2, sealing the ends of the slide 41 and preventing the sliding components 3 from accidentally dislodging during sliding. When it is necessary to remove a certain take-up roller 2 for maintenance or replacement, simply unscrew the screws 1-2 at one end of the slide 41, remove the baffle 411 at that location, and the take-up roller 2, along with the sliding components 3 at both ends, can be directly pulled out from the opening end of the slide 41. The entire process requires no disassembly of any other parts.

[0028] Based on the above technical solution, two limiting rings 21 are also fitted on each take-up roller 2. These two limiting rings 21 can be fixed near both ends of the take-up roller 2. Their function is to clamp the wound film from both sides to prevent the film from becoming axially loose or deviating during the take-up and unwinding process, thus ensuring the neatness of the film roll.

[0029] Based on the above technical solution, a caster wheel 6 is installed at each of the four corners of the bottom of the base frame 1. This design allows the entire drying rack to be easily moved inside the workshop or laboratory.

[0030] It should be noted that the term "drying rack" in the title of this patent is defined as follows: The "drying rack" described in this utility model specifically refers to a process carrier rack used to support and transport the film winding roller 2 during the film manufacturing, printing, coating, and drying processes. Its core function is to safely and efficiently support and transport the film before, during, and after the drying process. It does not directly provide a heat source or other drying functions, but rather indirectly achieves the drying purpose of the film by moving it to an external environment with drying conditions such as drying tunnels, ovens, or drying yards.

[0031] This invention utilizes a buffer assembly and a buffer platform 530, each consisting of a mounting shell 5, a fixing post 51, an elastic element 52, and a contact platform 53, mounted on two adjacent sliding components 3 within the same slide groove 41. When the sliding components 3 are driven by external force to bring the take-up rollers 2 closer together, the buffer platform 530 contacts the contact platform 53 and compresses the elastic element 52. This process directly converts the kinetic energy of the sliding components 3 into elastic potential energy, which is absorbed and released through the deformation of the elastic element 52. This mechanism achieves automatic buffering and stopping without external intervention at the physical level, effectively preventing rigid collisions of the take-up rollers 2 caused by operational impacts or equipment vibrations, thereby avoiding damage to the film material.

[0032] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
