Description

Technical Field

[0001] This utility model relates to the field of feeding rack technology, specifically a feeding rack for thermoplastic polyurethane film processing. Background Technology

[0002] Thermoplastic polyurethane film (TPU film) is a flexible polymer film made of thermoplastic polyurethane (TPU) material, combining the elasticity of rubber with the processing properties of plastic. Its molecular structure consists of alternating soft segments (polyether or polyester) and hard segments (diisocyanate and chain extender), giving it excellent abrasion resistance, high tensile strength, oil resistance, low temperature resistance, and moisture permeability.

[0003] In existing technologies, polyurethane film is typically stored using fixed-column racks or ordinary cantilever racks, which have fixed cantilever lengths and layer spacing, making it impossible to flexibly adjust according to the size of the goods. When storing thermoplastic polyurethane film rolls of varying lengths, if the roll length is less than the cantilever spacing, upper-level space is wasted; if the length exceeds the cantilever range, it cannot be stored properly, resulting in idle storage space. Therefore, we propose a material handling rack for thermoplastic polyurethane film processing. Utility Model Content

[0004] The purpose of this invention is to provide a material rack for processing thermoplastic polyurethane film, addressing the problem that the aforementioned methods for storing polyurethane film often employ fixed column racks or ordinary cantilever racks, whose cantilever lengths and layer spacing are fixed and cannot be flexibly adjusted according to the size of the goods. When storing thermoplastic polyurethane film rolls of varying lengths, if the roll length is less than the cantilever spacing, upper-layer space is wasted; if the length exceeds the cantilever range, it cannot be stored properly, resulting in idle storage space.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a feeding rack for processing thermoplastic polyurethane film, comprising: a feeding rack body, a fixing plate fixedly connected to one end of the feeding rack body, a support plate fixedly connected to the bottom of the fixing plate, a fixing frame fixedly connected to the top of the support plate, a telescopic mechanism provided inside the fixing frame, and a quick-release mechanism provided at one end of the fixing frame.

[0006] Preferably, the telescopic mechanism includes a worm gear installed on the inner wall of the fixed frame, one end of the worm gear meshing with a worm wheel, a rotating shaft installed at the axis of the worm wheel, a gear installed on the outer wall of the rotating shaft, and a rack meshing with one end of the gear.

[0007] Preferably, the quick-release mechanism includes a mounting cylinder fixedly connected to one end of the worm gear, the outer wall of the mounting cylinder having a convex groove, and the inner wall of the mounting cylinder having a spring installed.

[0008] Preferably, an installation column is placed on the inner wall of the installation cylinder, and a limit column is fixedly connected to the outer wall of the installation column.

[0009] Preferably, one end of the mounting post is fixedly connected to a connecting post, and one end of the connecting post is fixedly connected to a handle.

[0010] Preferably, a telescopic plate is fixedly connected to one end of the rack, an anti-slip plate is fixedly connected to the upper surface of the telescopic plate, and baffles are fixedly connected to the four corners of the upper surface of the telescopic plate.

[0011] This utility model has at least the following beneficial effects:

[0012] (1) The telescopic mechanism can be flexibly adjusted according to the actual length of goods such as thermoplastic polyurethane film rolls. When storing film rolls of different specifications, if the roll length is short, the telescopic plate can be retracted to avoid wasting the upper space due to the fixed telescopic plate. If the roll length is unusual, the telescopic plate can be extended to ensure normal storage, make full use of the storage space, reduce idle space, and abandon the simple stacking storage mode. By relying on the vertical layering and telescopic cantilever structure, multi-layer independent storage can be achieved, which greatly improves the space utilization rate.

[0013] (2) Through the designed quick-release mechanism, the handle can be installed and switched between multiple feeding racks, needle

[0014] For multi-layered

[0015] With this material rack, workers do not need to equip each layer with a dedicated fixed handle. Through simple disassembly and installation, they can drive the telescopic plates of different material racks. When not in use, the handle can be removed from the material rack and stored in a tool cabinet or designated small space, avoiding the long-term protrusion of the handle occupying the passage and operation area space.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a feeding rack for processing thermoplastic polyurethane film, comprising: a feeding rack body 1, a fixing plate 2 fixedly connected to one end of the feeding rack body 1, a support plate 3 fixedly connected to the bottom of the fixing plate 2, a fixing frame 4 fixedly connected to the top of the support plate 3, a telescopic mechanism 5 provided inside the fixing frame 4, a quick-release mechanism 6 provided at one end of the fixing frame 4, the telescopic mechanism 5 including a worm gear 51 installed on the inner wall of the fixing frame 4, a worm wheel 52 meshing at one end of the worm gear 51, a rotating shaft 53 installed at the axis of the worm wheel 52, and a gear 54 installed on the outer wall of the rotating shaft 53. One end of the rack 55 is engaged with the quick-release mechanism 6, which includes a mounting cylinder 61 fixedly connected to one end of the worm gear 51. The outer wall of the mounting cylinder 61 is provided with a convex groove 62. A spring 63 is installed on the inner wall of the mounting cylinder 61. A mounting post 64 is placed on the inner wall of the mounting cylinder 61. A limit post 65 is fixedly connected to the outer wall of the mounting post 64. A connecting post 66 is fixedly connected to one end of the mounting post 64. A handle 67 is fixedly connected to one end of the connecting post 66. A telescopic plate 7 is fixedly connected to one end of the rack 55. An anti-slip plate 8 is fixedly connected to the upper surface of the telescopic plate 7. Baffles 9 are fixedly connected to the four corners of the upper surface of the telescopic plate 7.

[0024] When in use, the operator places the processed thermoplastic polyurethane film on the telescopic plate 7. The anti-slip plate 8 has a special textured design to increase the friction with the thermoplastic polyurethane film roll. During feeding, receiving or moving of the telescopic plate 7, even if there is vibration or tilting, the goods are not easy to slide or move, avoiding feeding interruption and material damage caused by the roll slipping, and ensuring the continuous and stable processing flow. When adjustment of the telescopic plate 7 is required, the operator installs the handle 67 into the mounting cylinder 61. At this time, the limiting post 65 enters the mounting cylinder 61 along the convex groove 62, and the mounting post 64 abuts against the spring 63. Then, the operator rotates the handle 67 to fix the limiting post 65 at the bottom of the convex groove 62, thus fixing the handle 67 onto the mounting cylinder 61. At this time, the spring 63 is in a compressed state, which can make the limiting post 65 more firmly fixed on the convex groove 62. Then, the operator rotates the handle 67, which drives the worm gear 51 to rotate. The rotation of the worm gear 51 drives the worm wheel 52 to rotate. The rotation of the worm wheel 52 drives the rotating shaft 53 to rotate. The rotation of the rotating shaft 53 drives the gear 54 to rotate. The rotation of the gear 54 drives the rack 55 to move back and forth, thereby driving the telescopic plate 7 to move back and forth on the fixed plate 2.

[0025] The telescopic mechanism 5 can be flexibly adjusted according to the actual length of goods such as thermoplastic polyurethane film rolls. When storing film rolls of different specifications, if the roll length is short, the telescopic plate 7 can be retracted to avoid wasting upper space due to the fixed telescopic plate 7. If the roll length is excessive, the telescopic plate 7 can be extended to ensure normal storage, make full use of storage space, reduce idle space, and abandon the simple stacking storage mode. By relying on vertical layering and telescopic cantilever structure, multi-layer independent storage can be achieved, which greatly improves space utilization.

[0026] When it is necessary to install the handle 67 onto another shelf, the operator rotates the handle 67 in the opposite direction, causing the limiting post 65 to disengage from the groove at the bottom of the convex groove 62. At this time, the spring 63 returns, and the limiting post 65 moves out along the convex groove 62, thus removing the handle 67 from the mounting cylinder 61 and installing it onto another shelf. Through the set quick-installation mechanism 6, the handle 67 can be installed and switched between multiple material feeding racks. For multi-layer material feeding racks, workers do not need to equip each layer with a dedicated fixed handle 67. Through simple disassembly and installation, the telescopic plates 7 of different material feeding racks can be moved. When the handle 67 is not in use, it can be removed from the material feeding rack and stored in a tool cabinet or designated small space, avoiding the handle 67 from protruding outwards for a long time and occupying the aisle and operating area space.
