Description

Technical Field

[0001] The present application relates to the technical field of inkjet printing equipment, and in particular, to a hoisting structure for a vertical double-sided inkjet printer. Background Art

[0002] Vertical double-sided inkjet printers are a type of printer that has developed rapidly in recent years. Their typical feature is that two printer heads of the printer are located on the left and right sides of the printing channel, and the printing medium moves up and down or down and up to achieve step-by-step printing. By controlling the printer nozzles, completely different patterns or overlapping patterns can be printed on both sides of the printing medium, which is applied to some scenarios that require double-sided display, such as large transparent window posters, hanging posters, or knitted products.

[0003] Existing vertical double-sided inkjet printers usually include an inkjet printer main body, a unwind roller and a windup roller installed on the inkjet printer main body. The unwind roller and the windup roller are located on the same side of the inkjet printer main body, and usually the unwind roller is located above the windup roller. During the feeding process, usually the unwind roller needs to be removed first, then the material roll is threaded through the unwind roller, and then the unwind roller equipped with the material roll is reinstalled on the inkjet printer main body to complete the feeding. Since the unwind roller equipped with the material roll is relatively heavy as a whole, and coupled with the relatively large overall size of the inkjet printer main body, it is very difficult to achieve the reinstallation of the unwind roller on the inkjet printer main body only by manual handling, and usually a hoisting device needs to be used to assist manual lifting of the material roll.

[0004] However, in practical applications, the sizes, weights, etc. of different models of vertical double-sided inkjet printers are different, and each feeding process of the inkjet printer requires the assistance of a hoisting device. And the hoisting device is usually installed in the workshop. Therefore, before using the inkjet printer, it is necessary to ensure that the entire inkjet printer is located within the working area of the hoisting device, which has relatively high requirements for the position and use. In addition, during each feeding process, the hook of the hoisting device needs to be moved to the vicinity of the inkjet printer first, which is inconvenient to use. Summary of the Utility Model

[0005] In order to solve the problem that each feeding process of the inkjet printer in the prior art requires the assistance of a hoisting device, resulting in limited use position and inconvenient use process, the present application provides a hoisting structure for a vertical double-sided inkjet printer.

[0006] A hoisting structure for a vertical double-sided inkjet printer provided by the present application adopts the following technical solutions:

[0007] A hoisting structure for a vertical double-sided inkjet printer includes an inkjet printer main body, an installation seat is arranged on the inkjet printer main body, and a hoisting mechanism for hoisting a material roll to a specified position on the inkjet printer main body is arranged on the installation seat.

[0008] By adopting the above technical solution, during use, the staff first installs the hoisting mechanism on the mounting base, then hoists the whole to the top of the inkjet printer main body, and fixes it on the inkjet printer main body through the mounting base, thereby fixing the hoisting mechanism on the inkjet printer main body. When feeding is required, the hoisting mechanism can assist the staff in hoisting the material roll. Compared with the prior art that requires the aid of a crane equipment, the usage requirements are lower and the overall use is simpler and more convenient.

[0009] Preferably, the mounting base includes a fixing frame fixed to the top of the inkjet printer main body, two first sliders slidably arranged on the fixing frame, and a connecting rod arranged between the two first sliders. The two first sliders are arranged at intervals along the length direction of the inkjet printer main body. The two ends of the connecting rod are respectively fixedly connected to a first slider. There are two groups of hoisting mechanisms, and the two groups of hoisting mechanisms are arranged in one-to-one correspondence with the two first sliders. A first driving component for driving the first slider to slide along the length direction of the inkjet printer main body is arranged on the fixing frame.

[0010] By adopting the above technical solution, during use, the two first sliders are driven to slide synchronously by the first driving component, thereby driving the two groups of hoisting mechanisms to slide synchronously, so as to realize the adjustment of the positions of the two groups of hoisting mechanisms, ensure that the two groups of hoisting mechanisms are at both ends of the length direction of the material roll during the feeding process, thus ensuring the stability during the hoisting process, and further ensuring the stability during the feeding process.

[0011] Preferably, the first driving component includes a rack fixed to the fixing frame, a first driving gear rotatably arranged on the connecting rod, and a first driving motor arranged on the connecting rod for driving the first driving gear to rotate. The first driving gear is meshed with the rack, and the length direction of the rack is parallel to the length direction of the inkjet printer main body.

[0012] By adopting the above technical solution, during use, the output shaft of the first driving motor rotates to drive the first driving gear to rotate. Under the cooperation of the rack, when the first driving gear rotates, it will move along the length direction of the rack, thereby driving the two first sliders and the connecting rod to slide synchronously, and further realizing the adjustment of the positions of the two groups of hoisting mechanisms.

[0013] Preferably, the hoisting mechanism includes a second slider slidably arranged on the first slider along the width direction of the inkjet printer main body, a first driving cylinder arranged on the first slider for driving the second slider to slide, and an electric hoist fixed to the second slider for hoisting the material roll.

[0014] By adopting the above technical solution, when in use, the second slider is driven to slide by the first driving cylinder, so that the electric hoist installed on the second slider extends outside the main body of the printer. Then, the lifting of the material roll can be realized by the coordinated use of the two electric hoists, and the use is simple and convenient.

[0015] Preferably, the lifting mechanism includes a third slider slidably arranged on the first slider along the width direction of the main body of the printer, a second driving cylinder arranged on the first slider for driving the third slider to slide, a winding wheel and a guiding wheel rotatably arranged on the third slider, and a lifting rope arranged between the winding wheel and the guiding wheel. The winding wheel and the guiding wheel are spaced apart on the third slider. One end of the lifting rope is wound around the winding wheel, and the other end of the lifting rope is used to lift the material roll after passing around the guiding wheel. A second driving component is further arranged on the third slider for driving the winding wheels in the two groups of lifting mechanisms to rotate synchronously.

[0016] By adopting the above technical solution, when in use, the third slider is driven to slide by the second driving cylinder until the lifting rope on the third slider extends outside the main body of the printer. Then, the second driving component is used to drive the two winding wheels to rotate synchronously to unwind the lifting rope. After that, the staff connects the lifting ropes to one end of the material roll respectively, and then the second driving component can be used to drive the two winding wheels to rotate synchronously to wind up, so as to drive the material roll to rise through the lifting rope, thereby realizing the lifting of the material roll. The overall use is simple and convenient, and at the same time, the stability of the material roll during the rising process is ensured.

[0017] Preferably, the second driving component includes a linkage shaft rotatably arranged on the connecting rod for connecting the two winding wheels together, and a second driving gear rotatably arranged on the third slider. The two winding wheels and the two second driving gears are coaxially fixed on the linkage shaft. A third driving gear and a second driving motor for driving the third driving gear to rotate are arranged on one of the third sliders. The second driving gear and the third driving gear are meshed with each other.

[0018] By adopting the above technical solution, when in use, the output shaft of the second driving motor rotates to drive the third driving gear to rotate. The rotation of the third driving gear synchronously drives the second driving gear to rotate, so as to drive the linkage shaft to rotate, thereby driving the two winding wheels to rotate synchronously, and further realizing the synchronous winding or unwinding of the winding wheels in the two groups of lifting mechanisms.

[0019] Preferably, an auxiliary feeding component is arranged at one end of the first slider away from the second slider for assisting the staff to wind the material around the main body of the printer.

[0020] By adopting the above technical solution, when feeding at the unwinding roller, since the main body of the inkjet printer is relatively high, at this time, the auxiliary feeding assembly can assist the operator in winding one end of the material roll around the main body of the inkjet printer, thus facilitating subsequent printing.

[0021] Preferably, the auxiliary feeding assembly includes a fourth slider sliding on the first slider along the width direction of the main body of the inkjet printer, a third driving cylinder arranged on the connecting rod for driving the fourth slider to slide, a fourth driving cylinder arranged on the fourth slider, a fifth slider arranged at the end of the piston rod of the fourth driving cylinder, and a clamping member arranged on the fifth slider for clamping the material, and the fifth slider slides along the height direction of the main body of the inkjet printer.

[0022] By adopting the above technical solution, in use, first drive the fifth slider to move downward through the fourth driving cylinder, and drive the clamping member to move downward. Then, the operator moves one end of the material roll to the clamping member and clamps and fixes it through the clamping member. Then, drive the clamping member to rise through the fourth driving cylinder, and at the same time drive the fourth slider to move through the third driving cylinder until the whole clamping member passes over the top of the main body of the inkjet printer, and after one end of the material roll is wound around the main body of the inkjet printer, the operator can remove the material, so as to achieve the purpose of assisting the operator in winding the material roll around the main body of the inkjet printer.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. During use, directly install the hoisting mechanism on the top of the main body of the inkjet printer through the mounting seat. Thus, during the subsequent feeding process, adjust the two hoisting mechanisms at both ends in the length direction of the material roll through the first driving component, and then through the cooperation of the first driving cylinder and the electric hoist, realize the hoisting and feeding of the material roll. Compared with the prior art that needs to rely on a crane device, the usage requirements are lower, and the overall use is simpler and more convenient;

[0025] 2. Through the cooperation of the second driving cylinder, the second driving component, the take-up wheel, the guide wheel and the suspension rope, realize the synchronous lifting of both ends of the material roll, thereby ensuring the stability of the material roll during the rising process, and further ensuring the stability of the feeding process;

[0026] 3. During use, the auxiliary feeding assembly assists the operator in winding one end of the material roll around the top of the main body of the inkjet printer, improving the convenience of the feeding process. Description of the Drawings

Detailed implementation manners

[0037] The following will further describe the present application in detail with reference to the appended Figure 1 - appended Figure 9 drawings.

[0038] The embodiment of the present application discloses a hoisting structure for a vertical double-sided inkjet printer.

[0039] Embodiment 1:

[0040] Refer to Figure 1 and Figure 2, a hoisting structure for a vertical double-sided printer, including a printer main body 1 standing on the ground. There is a mounting seat 2 at the top of the printer main body 1. The mounting seat 2 is composed of a fixing frame 21, a first slider 22 and a connecting rod 23. Among them, the fixing frame 21 is fixedly connected to the top of the printer main body 1 by bolts. There are two first sliders 22, and the two first sliders 22 are arranged at intervals along the length direction of the printer main body 1. The first slider 22 is slidably connected to the fixing frame 21, and the sliding direction of the first slider 22 is along the length direction of the printer main body 1. The connecting rod 23 is located between the two first sliders 22, and both ends of the connecting rod 23 are fixedly connected to a first slider 22 by bolts. A first driving assembly 4 is arranged on the fixing frame 21. A set of hoisting mechanisms 3 are arranged on each first slider 22, and the two sets of hoisting mechanisms 3 are symmetrically arranged.

[0041] Refer to Figure 1 and Figure 2 , during use, the two first sliders 22 are connected together through the connecting rod 23, so that the two sets of hoisting mechanisms 3 are combined together. When the first slider 22 is driven to slide by the first driving assembly 4 subsequently, the two sets of hoisting mechanisms 3 can be driven to move synchronously, so that before lifting the material roll, the hoisting mechanisms 3 can be moved to both sides in the length direction of the material roll, thereby ensuring the stability during the process of lifting the material roll by the hoisting mechanisms 3.

[0042] Refer to Figure 2 and Figure 3 , the first driving assembly 4 is composed of a rack 41, a first driving gear 42 and a first driving motor 43. Among them, the rack 41 is fixedly connected to the fixing frame 21 by bolts, and the length direction of the rack 41 is parallel to the length direction of the printer main body 1. The first driving gear 42 is rotatably connected to the connecting rod 23, the first driving gear 42 meshes with the rack 41, the first driving motor 43 is fixedly connected to the connecting rod 23 by bolts, and the output shaft of the first driving motor 43 is coaxially and fixedly connected to the first driving gear 42; during use, the output shaft of the first driving motor 43 rotates to drive the first driving gear 42 to rotate. Under the cooperation of the rack 41, the first driving gear 42 rotates to drive the connecting rod 23 and the two first sliders 22 to slide synchronously, so as to realize the adjustment of the position of the hoisting mechanism 3.

[0043] Refer to Figure 2 and Figure 4, the hoisting mechanism 3 is composed of a second slider 31, a first driving cylinder 32 and a electric hoist 33. Among them, the second slider 31 is slidably arranged on the first slider 22 along the width direction of the printer main body 1. The cylinder block of the first driving cylinder 32 is fixed on the first slider 22 by bolts. The piston rod of the first driving cylinder 32 is fixedly connected to the second slider 31. The electric hoist 33 is installed on the end of the second slider 31 away from the first slider 22 by bolts. When in use, after the hoisting mechanism 3 moves to the designated position, the piston rod of the first driving cylinder 32 can extend to drive the second slider 31 to slide away from the first slider 22. The sliding of the second slider 31 synchronously drives the electric hoist 33 to slide. Until the electric hoist 33 moves to the outside of the printer main body 1, the electric hoist 33 can be used to lift the material roll on the periphery of the printer main body 1.

[0044] Refer to Figure 4 and Figure 5 , at the same time, after installing the unwinding roller with the material roll on the printer main body 1, the staff needs to first guide one end of the material 7 to wind around the printer main body 1. Since the overall height of the printer main body 1 is relatively high, it is extremely inconvenient to rely only on manual operation during the process of winding one end of the material 7 at the unwinding roller around the top of the printer main body 1. In order to improve the convenience of the winding operation of the material 7, an auxiliary feeding component 6 is arranged at the end of the first slider 22 away from the second slider 31.

[0045] Refer to Figure 4 and Figure 5 , when in use, the auxiliary feeding component 6 is arranged on the first slider 22. The sliding of the first slider 22 can drive the auxiliary feeding component 6 to slide synchronously, so as to adapt to material rolls at different positions, without the need to adjust the position of the auxiliary feeding component 6 separately. Then, the auxiliary feeding component 6 can assist the staff to wind the material 7 around the top of the printer main body 1, thereby improving the overall convenience of the equipment.

[0046] Refer to Figure 5 and Figure 6 , the auxiliary feeding component 6 is composed of a fourth slider 61, a third driving cylinder 62, a fourth driving cylinder 63, a fifth slider 64 and a clamping member 65. Among them, the fourth slider 61 is slidably connected to the first slider 22 along the width direction of the printer main body 1. The cylinder block of the third driving cylinder 62 is fixed on the connecting rod 23 by bolts. The piston rod of the third driving cylinder 62 is fixedly connected to the fourth slider 61 by bolts. The fourth driving cylinder 63 is installed on the fourth slider 61, and the piston rod of the fourth driving cylinder 63 is arranged vertically downward. The end of the piston rod of the fourth driving cylinder 63 is fixedly connected to the fifth slider 64. The clamping member 65 is arranged on the fifth slider 64. In this embodiment, the clamping member 65 is preferably set as a finger cylinder, and the clamping end of the finger cylinder faces away from the second slider 31.

[0047] Reference Figure 5 and Figure 6 When in use, in the initial state, the clamping member 65 is located at the front side of the printer body 1, and the clamping end of the clamping member 65 is arranged toward the rear side of the printer body 1. After the staff installs the material roll on the printer body 1, they can pull one end of the material 7 wound on the material roll and guide it to move to the clamping end of the clamping member 65, and clamp and fix it through the clamping member 65. Then, through the cooperation of the third driving cylinder 62 and the fourth driving cylinder 63, one end of the material 7 is passed around the top of the printer body 1 and moved to the rear side of the printer body 1. Finally, the staff stands at the rear side of the printer body 1, removes the material 7 and completes the subsequent winding, so as to achieve the purpose of assisting the staff to wind the material 7 on the printer body 1, and the overall use is more convenient.

[0048] The implementation principle of the embodiment of the present application is as follows: when in use, the material roll is first transported to the vicinity of the printer body 1, and then the first drive motor 43 drives the first drive gear 42 to rotate, and under the cooperation of the rack 41, the hoisting mechanism 3 installed on the first slider 22 is moved close to the material roll, and the two sets of hoisting mechanisms 3 are symmetrically distributed at both ends of the length direction of the material roll, and then the piston rod of the first drive cylinder 32 is extended to drive the second slider 31 to slide, so that the electric hoist 33 is moved and extended to the outside of the printer body 1, and then the staff can lift the material roll and The electric hoist 33 is connected, and the material roll can be hoisted and transported to the designated position on the printer body 1 through the electric hoist 33; when the material roll is installed on the printer body 1, the third driving cylinder 62, the fourth driving cylinder 63 and the clamping member 65 are used in coordination to assist the staff to pull the material 7 around the printer body 1, so as to realize the material roll loading process; compared with the prior art method of loading with the help of overhead crane equipment, the overall use is more convenient, and it can be applied to different positions, which is more convenient for actual production applications.

[0049] The difference between Example 2 and Example 1 is that:

[0050] Reference Figure 7 and Figure 8 In this embodiment, the first driving assembly 4 is composed of a screw rod 44 rotating on the fixed frame 21, a threaded sleeve 45 threadedly matched with the screw rod 44, and a third driving motor 46 for driving the screw rod 44 to rotate, wherein the length direction of the screw rod 44 is parallel to the length direction of the printer body 1, two threaded sleeves 45 are provided, and the two threaded sleeves 45 are spaced apart along the length direction of the screw rod 44, the two threaded sleeves 45 are respectively fixedly connected to a first slider 22, the third driving motor 46 is fixed to the fixed frame 21 by bolts, and the output shaft of the third driving motor 46 is coaxially fixedly connected to the screw rod 44.

[0051] Reference Figure 7 and Figure 8 During use, the output shaft of the third driving motor 46 rotates to drive the lead screw 44 to rotate. The rotation of the lead screw 44 synchronously drives the two threaded sleeves 45 to slide. The sliding of the threaded sleeves 45 drives the first slider 22 and the hoisting mechanism 3 mounted on the first slider 22 to slide, thereby realizing the adjustment of the position of the hoisting mechanism 3. The overall use process is simple and convenient.

[0052] Reference Figure 7 and Figure 9 The hoisting mechanism 3 may also be composed of a third slider 34, a second driving cylinder 35, a winding wheel 36, a guiding wheel 37 and a hoisting rope 38. Among them, the third slider 34 is slidably arranged on the first slider 22. The sliding direction of the third slider 34 is parallel to the width direction of the inkjet printer main body 1. The cylinder block of the second driving cylinder 35 is fixed on the first slider 22. The piston rod of the second driving cylinder 35 is fixedly connected to the third slider 34. The winding wheel 36 and the guiding wheel 37 are both rotatably connected to the third slider 34. And the winding wheel 36 is located at one end of the third slider 34 close to the first slider 22, and the guiding wheel 37 is located at one end of the third slider 34 far from the first slider 22. One end of the hoisting rope 38 is wound around the winding wheel 36, and the other end of the hoisting rope 38 is suspended after passing around the guiding wheel 37.

[0053] Reference Figure 7 and Figure 9 A second driving component 5 is further arranged on the third slider 34. The second driving component 5 is composed of a linkage shaft 51 and a second driving gear 52. The linkage shaft 51 rotates on the third slider 34, and the linkage shaft 51 is located between the two winding wheels 36. The second driving gear 52 is located on one side of the winding wheel 36. The two winding wheels 36 and the two second driving gears 52 are coaxially fixed on the linkage shaft 51. A second driving motor 54 and a third driving gear 53 are further arranged on one of the third sliders 34. The second driving motor 54 is fixed on the third slider 34 by bolts. The third driving gear 53 rotates on the third slider 34, and the third driving gear 53 is coaxially fixedly connected to the output shaft of the second driving motor 54. The second driving gear 52 and the third driving gear 53 are meshed with each other. In this embodiment, the outer diameter of the second driving gear 52 is larger than the outer diameter of the third driving gear 53.

[0054] Reference Figure 7 and Figure 9, during use, one end of the lifting rope 38 is used for hoisting the coil after passing around the guide wheel 37. When the third slider 34 extends out of the main body 1 of the inkjet printer and is located above the coil, the second drive motor 54 can be used to drive the third drive gear 53 to rotate, thereby driving the second drive gear 52 to rotate, and then driving the winding wheel 36 to rotate. At this time, the synchronous rotation of the two winding wheels 36 can be realized through the linkage shaft 51, and then the two lifting ropes 38 can be wound or unwound synchronously. Compared with the method in Embodiment 1 where two electric hoists 33 are required to unwind respectively, it is more convenient to use and also ensures the stability of both ends of the coil during the hoisting process of the coil.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
