Description

Technical Field

[0001] This utility model relates to the field of industrial printers, specifically to an industrial printing roll unwinding and rewinding device that facilitates loading and unloading. Background Technology

[0002] To improve transportation efficiency, industrial paper rolls or industrial fabric rolls are typically tens of thousands of meters long. However, existing printers' built-in paper loading and unloading systems cannot directly handle these lengths. Typically, specialized equipment is needed to wind the massive industrial rolls into multiple smaller rolls, each hundreds or thousands of meters long. This process requires multiple unwinding and rewinding operations, is labor-intensive, and necessitates reserving space for hoisting equipment.

[0003] For example, utility model patent CN221190867U discloses a 10,000-meter printer loading and unloading system and a 10,000-meter printer, including a hoisting assembly and an unwinding roller assembly and a rewinding roller assembly disposed below the hoisting assembly. The hoisting assembly includes a support frame, a pair of overhead trolley tracks at the top of the support frame, a movable crossbeam between the pair of overhead trolley tracks, a traveling trolley on the movable crossbeam, and a hook connected to the bottom of the traveling trolley. The unwinding roller assembly includes a pair of unwinding support plates, with a fabric unwinding roller connected between the pair of unwinding support plates. The rewinding roller assembly includes a pair of rewinding support plates, with a rewinding roller connected between the pair of rewinding support plates. This 10,000-meter printer loading and unloading system can directly utilize the hoisting assembly for lifting industrial paper rolls or industrial fabric rolls using an overhead trolley, thereby allowing paper loading or unloading operations to be performed from above the unwinding roller assembly and the rewinding roller assembly, avoiding the limitations of space constraints during the loading and unloading process using forklifts. However, the 10,000-meter printer roll-up and roll-down system and the 10,000-meter printer still require external hoisting equipment, which is costly and inconvenient for loading and unloading rolls. Utility Model Content

[0004] In order to facilitate the loading and unloading operation and realize the loading and unloading function of the winding and unloading device, the technical solution adopted by this utility model is: an industrial printing winding and unloading device that facilitates loading and unloading, including a rotating support shaft, a drive mechanism, a pair of paper roll lifting arms and a pair of support plates.

[0005] The rotating support shaft is disposed between the pair of support plates. The drive mechanism is mounted on the support plates and is connected to the rotating support shaft for transmission. The drive mechanism is used to drive the rotating support shaft to rotate, thereby driving the paper roll lifting arm to rotate.

[0006] A pair of paper roll lifting arms are respectively disposed at both ends of the rotating support shaft, and are used to lift the paper roll onto the support plate or remove the paper roll from the support plate under the rotation of the rotating support shaft.

[0007] Based on the above, in order to facilitate the rotation of the rotating support shaft, the driving mechanism includes a pair of driving cylinders, and each end of the rotating support shaft is provided with a force-applying arm. Each force-applying arm is connected to the extension end of the corresponding driving cylinder, and the axial projection of the force-applying arm intersects with the axial projection of the paper roll lifting arm.

[0008] Based on the above, it is convenient to use drive cylinders to push the force-applying arm. A pair of drive cylinders are respectively installed on the outer side of the support plate in a downward-sloping position. This allows the drive cylinders to lift the paper roll onto the support plate when they extend, and to rotate the paper roll lifting arm to a horizontal position when they retract.

[0009] Based on the above, in order to facilitate support, a paper roller is provided at the center of the paper roll, and a paper roller mounting groove for accommodating the paper roller is provided on the support plate.

[0010] Based on the above, the two ends of the paper roller are respectively extended from the support plate.

[0011] Based on the above, in order to improve the operational safety of the equipment, a protective railing is connected between the rear parts of the pair of support plates, and the top of the protective railing is set higher than the top of the support plate.

[0012] Based on the above, in order to increase the structural stability of the equipment, a crossbeam and several fabric winding rollers are also provided between the rear parts of the pair of support plates.

[0013] Based on the above, in order to achieve powered winding and unwinding, driven gears and bearings are respectively provided at both ends of the paper roller, a drive motor is provided on the support plate, and a drive gear that meshes with the driven gear is provided on the drive motor. The two ends of the paper roller are rotatably engaged with the paper roller mounting groove through the bearings.

[0014] Based on the above, in order to improve the safety of the equipment, a protective cover is provided on the outer side of the pair of support plates.

[0015] This utility model has substantial features and advancements compared to the prior art. Specifically, the industrial printing roll-up and unwinding device provided by this utility model facilitates loading and unloading of materials. By setting a rotating support shaft on a support plate and a paper roll lifting arm on the rotating support shaft for lifting the paper roll, and setting a force-applying arm at the end of the rotating support shaft, the force-applying arm can be rotated by the extension and retraction of the drive cylinder. Then, the rotating support shaft drives the paper roll lifting arm to rotate and lift, realizing that the roll-up and unwinding device has its own loading and unloading function, thus facilitating loading and unloading operations.

[0016] Furthermore, by mounting the drive cylinder obliquely on the support plate, the extension rod of the drive cylinder forms a certain angle with the horizontal line, thereby facilitating the use of the drive cylinder to push the force-applying arm.

[0017] Furthermore, by extending the paper rolls out from both ends of the support plate and creating paper roll mounting slots on the support plate, the paper roll lifting arm can easily lift the paper rolls during the up and down winding operations.

[0018] Therefore, this industrial printing roll-up and unrolling device, which facilitates loading and unloading, has the function of easy loading and unloading operations and realizes the built-in loading and unloading function of the roll-up and unrolling device. Attached Figure Description

[0023] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0024] Example 1

[0025] This embodiment provides an industrial printing roll-up and unrolling device that facilitates loading and unloading, such as... Figure 1 , Figure 2 , Figure 3 As shown, the system includes a rotating support shaft 12, a drive mechanism, a pair of paper roll lifting arms 13, and a pair of support plates 3. The rotating support shaft 12 is disposed between the pair of support plates 3, and the drive mechanism is mounted on the support plates 3 and is drively connected to the rotating support shaft 12. The drive mechanism is used to drive the rotating support shaft 12 to rotate, thereby driving the paper roll lifting arms 13 to rotate.

[0026] A pair of paper roll lifting arms 13 are respectively disposed at both ends of the rotating support shaft 12, and are used to lift the paper roll 4 onto the support plate 3 or remove the paper roll 4 from the support plate 3 under the rotation of the rotating support shaft 12.

[0027] Specifically, in this embodiment, to facilitate the rotation of the rotating support shaft, the driving mechanism includes a pair of driving cylinders 10. Each end of the rotating support shaft 12 is provided with a force-applying arm 11, and each force-applying arm 11 is connected to the extension / retraction end of the corresponding driving cylinder 10. The axial projection of the force-applying arm 11 intersects with the axial projection of the paper roll lifting arm 13. The pair of driving cylinders 10 are respectively installed on the outer side of the support plate 3 in a downward-sloping posture. This allows the driving cylinders 10 to lift the paper roll 4 onto the support plate 3 when extended, and to rotate the paper roll lifting arm 13 to a horizontal position when retracted.

[0028] For ease of support, a paper roller 6 is centrally located on the paper roll 4, and a paper roller mounting groove 14 is provided on the support plate 3 to accommodate the paper roller 6. Both ends of the paper roller 6 extend out of the support plate 3. The paper roll support arm 13 is provided with slots for hooking the ends of the paper roller 6.

[0029] Example 2

[0030] This embodiment provides an industrial printing roll-up and unrolling device that facilitates loading and unloading. The main difference from Embodiment 1 is that, in this embodiment, to improve operational safety, a protective railing 1 is connected between the rear parts of the pair of support plates 3. The top of the protective railing 1 extends above the top of the support plates 3. To increase the structural stability of the device, a crossbeam 7 and several winding rollers 5 are also provided between the rear parts of the pair of support plates 3.

[0031] Example 3

[0032] This embodiment provides an industrial printing winding and unwinding device that facilitates loading and unloading. The main difference from Embodiment 1 is that, in this embodiment, to achieve powered winding and unwinding, driven gears 8 and bearings are respectively provided at both ends of the paper roller 6. A drive motor 9 is provided on the support plate 3, and a drive gear meshing with the driven gear 8 is provided on the drive motor 9. Both ends of the paper roller 6 are rotatably engaged with the paper roller mounting groove 14 via the bearings.

[0033] Example 4

[0034] This embodiment provides an industrial printing roll-up and unrolling device that facilitates loading and unloading. The main difference from Embodiment 1 is that, in order to improve the safety of the device, a protective cover 2 is provided on the outer side of the pair of support plates 3.

[0035] Specifically, the loading and unloading operation steps of the industrial printing roll-up and unloading device provided by this utility model are as follows:

[0036] When loading, first use a flatbed cart or other moving tool to move the paper roll 4 together with the paper roller 6 to one side of the rotating support shaft 12;

[0037] Then, the drive cylinder 10 is activated to retract, thereby pushing the force arm 11 to rotate around the axis of the rotating support shaft 12, so that the paper roll lifting arm 13 rotates synchronously around the axis of the rotating support shaft 12, and finally the paper roll lifting arm 13 rotates to a horizontal state.

[0038] Then, a flatbed truck or other mobile tool is used to move the paper roll to the top of the paper roll lifting arm 13, and the two ends of the paper roll 6 are hooked by the slots on the paper roll lifting arm 13.

[0039] Finally, the drive cylinder 10 is activated to extend it, thereby pushing the force arm 11 to rotate around the axis of the rotating support shaft 12. This causes the paper roll lifting arm 13 to rotate synchronously around the axis of the rotating support shaft 12, ultimately rotating the paper roll lifting arm 13 to a vertical position. This allows both ends of the paper roll 6 to engage in the paper roll mounting groove 14, ensuring that the driven gear on the paper roll is connected to the drive motor.

[0040] When rolling down to the next roll, reverse the above steps.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it; although the utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications can still be made to the specific implementation of this utility model or equivalent substitutions can be made to some technical features without departing from the spirit of the technical solution of this utility model, and all such modifications and substitutions should be covered within the scope of the technical solution claimed by this utility model.
