[0001] The invention relates to the technical field of printers, and in particular to a large-size material roll receiving device. Background Art

[0002] In the field of inkjet printer technology, printers are usually designed as all-in-one machines, including the entire process of loading, printing and receiving materials.

Therefore, it is necessary to design a separate material receiving and discharging device to solve this problem.

[0005] This involves many issues such as the load-bearing and transfer problems of the material rolls.

[0010] Based on the above, the top notch of the vertical constraint slide groove is a V-shaped notch, and the main area of ​​the vertical constraint slide groove has the same groove width.

[0011] Based on the above, the platform is a plane platform or a slope platform whose outer side is slightly lower than the inner side, and an inclined support plate is arranged on the outer side of the platform.

[0017] Based on the above, the gap of the clamping roller set is adjustable.

[0018] The present invention has outstanding substantive features and significant progress compared to the prior art. Specifically, the present invention has the following advantages: 1. Since the material collection device is mainly used to collect large-sized material rolls, and the diameter of large-sized material rolls is large, in the process of reeling, in order to avoid too much suspended material, a vertical constraint chute is set to make the center of gravity of the material roll movable, and the surface of the material roll can always fit closely with the roller system below, effectively preventing the suspended material from being too long and avoiding wrinkles in the material roll.

[0019] 2. As the material roll is too large and heavy, it is too difficult to load and unload the material roll by hoisting. Therefore, a flipping mechanism is set up to cooperate with the material roll support frame to flip as a whole. However, the two ends of the material roll are not fixed. When it is below the horizontal plane of the flipping system, the material roll can automatically slide from the material roll support frame into the carrier, which is convenient for unloading.

[0020] 3. The platform can also be tilted, and the unloading becomes a two-stage unloading, reducing the height difference with the ground or transfer vehicle.

[0021] 4. There are two forms of roller system design. Different structural forms are selected according to different usage scenarios to ensure the stability of material collection. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The technical solution of the present invention is further described in detail below through specific implementation methods.

[0030] Example 1 like Figure 1-Figure 3 As shown, a large-size material roll receiving device includes a base 1, a carrier 2, a material roll support frame 3, a roller system 4 and a turning mechanism 5.

[0031] The material roll support frame 3 includes two side frames 31 and vertical constraint slide grooves 32 arranged on the inner side of the frames, and the lower ends of the outer sides of the two side frames 31 are hinged to the base 1. The top notch of the vertical constraint slide groove 32 is a V-shaped notch, and the main area of ​​the vertical constraint slide groove 32 has the same groove width.

[0032] Among them, the core function of the vertical constraint slide groove 32 is to limit the rotating shaft 7 of the material roll 6. The rotating shaft 7 can slide freely in the vertical constraint slide groove 32. During the material roll winding process, as the winding thickness increases, the rotating shaft 7 gradually moves from bottom to top.

[0033] The flip mechanism 5 includes a telescopic rod whose rear end is hinged to the upper part of the base, and whose front end is hinged to the upper part of the stand 13. The telescopic rod pushes the material roll support frame to flip around the bottom hinge point. When unloading the material roll, the stand 31 is pushed down to at least horizontal, and the vertical constraint slide 32 is also rotated to at least horizontal or downwardly inclined state. The rotating shaft 7 is no longer restricted by the vertical constraint slide 32, and the entire material roll slides away from the material roll support frame 3. During the installation process, the main structure of the empty material roll is the rotating shaft 7, which can be lifted and installed inside the vertical constraint slide 32, or the rotating shaft 7 can be installed in the vertical constraint slide 32 according to the reverse operation of unloading and then reversed to the vertical state.

[0034] The platform 2 is arranged on the base 1 and is located on the flipping side of the material roll support frame 3. The platform 2 is a flat platform or an inclined platform with the outer side slightly lower than the inner side, which is used to cooperate with the action of the flipping mechanism 5. When unloading, the material roll is unloaded first and then onto the platform 2. An inclined support plate 21 is arranged on the outer side of the platform 2 to prevent the material roll 6 from escaping from the platform 2 under the action of inertia.

[0035] That is, the telescopic rod pushes the material roll support frame to flip as a whole, so that the material roll is separated from the material roll support frame and enters the carrier at the lowest position, and the two ends of the material roll are restricted in the vertical constraint slide groove at the highest position.

[0036] In a preferred embodiment, the inner end of the platform 2 is hinged to the base 1, and a platform telescopic rod 22 is connected between the outer side of the platform 2 and the base 1, and the platform telescopic rod 22 drives the outer side of the platform to flip downward to form a discharge slope.

[0037] In essence, a two-level unloading step is formed to avoid excessive height difference in unloading and prevent the material coil from being damaged during unloading.

[0038] The roller system 4 is arranged below the material roll support frame 3 for feeding material to the material roll support frame 3; specifically, in the present embodiment, the roller system 4 includes a first support roller 41, a first cloth winding roller 42, a second cloth winding roller 43, a clamping roller group 44 and other cloth winding rollers 45, the first support roller 41 is arranged below the material roll support frame 3 for supporting the material roll 6, the first cloth winding roller 42 has the same specifications as the first support roller 41 and is arranged at the same level, the second cloth winding roller 43 is arranged in the upper area of ​​the outer side of the first cloth winding roller 42 to cooperate with each other for adjusting the material to enter the material roll 6 at an angle higher than the upper end point of the first support roller 41, the clamping roller group 44 is arranged upstream of the first cloth winding roller 42 for providing preload and power for feeding, the other cloth winding rollers 45 are used for steering adjustment of feeding, and a feed port is arranged at the bottom of the base 1, the first cloth winding roller 42 and the clamping roller group 44 are power rollers, and the first cloth winding roller 42 and the first support roller 41 are driven by a chain or gear. A feeding guide plate 46 is provided between the clamping roller set 44 and the first cloth winding roller 42. The feeding guide plate 46 comprises an inclined portion connecting the gap of the clamping roller set and a curved portion connecting the surface of the first cloth winding roller. The inclined portion and the curved portion have a smooth transition.

[0039] In this embodiment, a pressure roller assembly 8 is also included, and the pressure roller assembly 8 includes a curved arm 81, a curved arm push rod 82 and a pressure roller 83 arranged on the non-flipping side of the material roll support frame 3. The span of the pressure roller 83 matches the span of the material roll support frame 3. The bottom end of the curved arm 81 is hinged to the base 1, and the two ends of the curved arm push rod 82 are respectively hinged to the curved arm 81 and the base 1. The curved arm push rod 82 is used to drive the curved arm to swing, thereby pressing the pressure roller against the surface of the material roll. Its main purpose is to prevent wrinkles on the surface of the material roll.

[0040] Working principle description: Taking the printing process as an example, the material wound on the roll is a printing medium, such as cloth, paper or film. After being exported from the printing device, the printing medium enters from the feed port below the base 1, and is first wound around other cloth winding rollers 45. After determining the conduction direction and a certain tensioning force, it enters the clamping roller group 44. The clamping distance of the clamping roller group 44 is adjustable, and the preload force can be adjusted. At the same time, the clamping roller group 44 has active power, which can drag and guide the printing medium to continue moving forward and be wound around the first cloth winding roller 42, and then transferred to the second cloth winding roller 43, and then enter the tangent between the first support roller 41 and the material roll 6 to start the entire material collection process.

[0041] As the material is wound, the diameter of the material roll 6 becomes larger and larger. When the material is wound or increases to a certain extent, the pressure roller assembly 8 abuts against the surface of the material roll 6 to ensure that the surface of the material roll is smooth.

[0042] During the winding process, the rotating shaft 7 gradually moves upward along the vertical constraint slide groove 32, and stops winding after reaching the preset winding diameter, cutting off the printing medium, and controlling the flipping mechanism 5 to push the material roll support frame 3 from vertical to horizontal or tilted downward, and the material roll is moved from the material roll support frame 3 to the carrier, and then the carrier is controlled to tilt and transfer the material roll from the carrier to the ground or other operating equipment.

[0043] The main function of the loading guide plate 46 is to realize automatic loading at a local position when there is no one to guide it. The printing medium is pushed by the clamping roller group 44 and moves along the loading guide plate 46 to the first cloth winding roller. The first cloth winding roller winds the printing medium upward under the rotation drive, and then the staff continues the remaining winding operation process, which provides a solution to the problem of manual cloth winding in the first cloth winding roller area and lack of cloth winding space.

[0044] Example 2 like Figure 4-Figure 6 As shown, the main difference between this embodiment and embodiment 1 is that: the roller system 4 includes a first support roller 41, a second support roller 47, a clamping roller group 44 and other cloth-winding rollers 45, the first support roller 41 and the second support roller 47 are arranged in parallel below the material roll support frame 3 for supporting the material roll 6, the clamping roller group 44 is arranged upstream of the second support roller 47 for providing preload and power for the feed, the other cloth-winding rollers 45 are used for steering adjustment of the feed, and a feed port is arranged at the bottom of the base, the first support roller 41 or the second support roller 47 is a power roller, the first support roller 41 and the second support roller 47 are driven by a chain or gear, the clamping roller group 44 is a power roller, and the gap of the clamping roller group is adjustable.

[0045] Furthermore, a feeding guide plate 46 is provided between the clamping roller set 44 and the second supporting roller 47, and the feeding guide plate 46 includes an inclined portion connecting the gap of the clamping roller set and a curved portion connecting the surface of the second supporting roller, and the inclined portion and the curved portion have a smooth transition.

[0046] In this embodiment, the upper material roll 6 is supported by two support rollers, and the three structures form a relatively stable triangular structure, so that the material collection process is more stable.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the present invention can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the present invention, which should be included in the scope of the technical solution for protection of the present invention.
