Description

Technical Field

[0001] The invention relates to the field of nitrocellulose production equipment, and in particular to a pulp roll feeding device and a feeding method. Background Art

[0002] In the pulp roll feeding process of nitrocellulose production, the existing method is to first clamp the pulp roll onto the feeding track by a forklift, then manually insert a pin into the pulp roll, set both ends of the pin on the feeding track, and finally let the pin carry the pulp roll to the slicer feeding platform for cutting.

[0003] The existing feeding method requires manual intervention in the threading link and subsequent links, with a low degree of automation and high labor intensity. There are certain safety risks that are not conducive to the automated production of pulp nitrocellulose. Especially when the production intensity is high, operators will inevitably deform their movements due to fatigue. The risks caused by this need to be solved by optimizing the feeding equipment and minimizing the dependence on manual labor. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a pulp roll feeding device and a feeding method which can automatically realize pulp roll feeding.

[0005] The technical solution adopted by the present invention to solve the technical problem is as follows: a pulp roll feeding device comprises two parallel guide rails, the front end of the guide rails is arranged on the front support, the end of the guide rails is arranged obliquely with the horizontal plane, and the front end of the guide rails is higher than the end of the guide rails; a through-pin slot structure is arranged at the end of the guide rails, the slot surface of the through-pin slot structure and the end of the guide rails are smoothly transitionally connected, a pulp roll feeding arm is arranged at the front end of the guide rails, and the feeding arm support surface of the pulp roll feeding arm is rotatably connected to the front end of the guide rails. The through-pin is lifted by the pulp roll feeding arm, thereby lifting the pulp roll on the through-pin. The through-pin rolls along the feeding arm support surface of the pulp roll feeding arm to the guide rails, and then rolls along the guide rails to the slot surface at the end of the guide rails. The slot surface clamps the through-pin to fix the pulp roll, thereby completing the feeding operation of the pulp roll. This solution saves a lot of manual operation links and ensures the safety and stability of the entire feeding process.

[0006] In order to prevent the pin from slipping off the pulp roll feeding arm at the beginning of the lifting of the pulp roll feeding arm and causing safety hazards, the following solution can be selected: the pulp roll feeding arm includes a pin baffle, which is arranged on the end of the feeding arm support surface away from the front end of the guide track, and the pin baffle extends upward in a direction perpendicular to the feeding arm support surface, and the pin baffle and the feeding arm support surface intersect to form a pin feeding slot. The pin feeding slot is a right-angle slot structure, which can well restrain the pin.

[0007] Furthermore, the pulp roll loading arm comprises a loading arm driving motor, and the loading arm driving motor drives the loading arm supporting surface to rotate around the front end of the guide track.

[0008] Furthermore, the pin-through slot structure includes a slot anti-collision pad, and the slot surface is arranged between the slot anti-collision pad and the end of the guide track. The pin rolling to the slot surface may pass over the slot surface under the action of inertia. In order to solve this safety hazard, the slot anti-collision pad can block the pin and buffer the pin.

[0009] Furthermore, the rear support includes a rear support frame and a support rod rotatably arranged on the rear support frame, the support rod and the rear support frame are threadedly connected, the support rod is arranged in a vertical direction, and the top of the support rod is connected to the end of the guide track through a spherical hinge structure. The support rod is rotated to achieve the rise and fall of the support rod, and the inclination of the guide track is adjusted, thereby adjusting the rolling speed of the pin. This solution can adjust the feeding progress according to the feeding needs in actual production.

[0010] A pulp roll feeding method comprises a pulp roll feeding device, including a through pin and a pulp roll, wherein the through pin passes through the pulp roll along the central axis direction of the pulp roll, and the two ends of the through pin are respectively clamped in a through pin feeding slot formed by the intersection of a loading arm support surface and a through pin baffle of a pulp roll loading arm, and then the loading arm driving motor is started to drive the loading arm support surface to rotate, and the through pin and the pulp roll are lifted upward, and then the through pin roll rolls along the loading arm support surface to a guide track and moves along the guide track until the slot surface is clamped and locked, thereby completing the pulp roll feeding operation.

[0011] The beneficial effects of the present invention are as follows: through the automatic loading of the pulp roll feeding device, not only the safety and stability of the pulp roll transportation during the production process is guaranteed, but also the feeding progress can be flexibly adjusted according to the production rhythm, so that the feeding structure can match the overall production rhythm. Specifically: 1. The present invention adopts an automatic feeding device to realize the automatic feeding process, replacing the original forklift and manual feeding methods, improving the degree of automation and the inherent safety of the process, and reducing labor intensity and safety risks. 2. The present invention adopts a lifting arm and a guide rail, and utilizes inertia to transport materials to the feeding platform, replacing the existing manual rolling of the pulp roll into the guide rail, reducing labor intensity. 3. The present invention avoids the cross-operation of forklifts and people, improves the inherent safety of the process, and reduces safety risks. 4. The present invention can be used for automatic feeding of coiled materials, reducing labor intensity, improving production efficiency, and reducing safety risks. The present invention is suitable for pulp roll feeding processes. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a schematic diagram of a pulp roll feeding device, a threading pin and a pulp roll of the present invention.

[0013] Marked in the figure are: pulp roll 1, through pin 2, guide rail 3, front end 31, end 32, slot surface 4, pulp roll feeding arm 5, through pin baffle 51, feeding arm supporting surface 52, feeding arm driving motor 6, rear support 7, slot anti-collision pad 8, front support 9. DETAILED DESCRIPTION

[0014] The present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0015] like Figure 1 The figure shows an embodiment of a pulp roll feeding device, as well as a through pin 2 and a pulp roll 1. The pulp roll 1 is cylindrical, and the through pin 2 passes through the pulp roll 1 along the axis of the pulp roll 1. Both ends of the through pin 2 extend outside the pulp roll 1, so as to be conveniently arranged on the feeding arm support surface 52 and the guide track 3 during the subsequent feeding operation.

[0016] The pulp roll feeding device mainly includes a pulp roll feeding arm 5 at the front end, a guide track 3 in the middle, and a slot surface 4 at the rear end. The feeding arm support surface 52 of the pulp roll feeding arm 5 is used to carry the through pin 2. One of the end surfaces of the feeding arm support surface 52 is provided with a through pin baffle 51, and the through pin baffle 51 can extend upward in a direction perpendicular to the feeding arm support surface 52. Generally, according to actual needs, the angle range between the through pin baffle 51 and the feeding arm support surface 52 can be set to 50° to 90°, and the angle range is an acute angle range as a whole, which can further improve the through pin feeding slot formed by the intersection of the through pin baffle 51 and the feeding arm support surface 52, and prevent the through pin 2 from slipping during the rotation of the feeding arm support surface 52 around the front end 31 of the guide track 3. The power for the feeding arm support surface 52 to lift upward is provided by the feeding arm drive motor 6. The other end face of the loading arm support surface 52, that is, the end face away from the through-pin baffle 51, can be rotatably arranged at the front end 31 of the guide track 3, and the specific rotation structure can be a rotating pin structure or a hinge structure. The end face of the loading arm support surface 52 is smoothly connected to the front end 31 of the guide track 3, ensuring that when the loading arm support surface 52 is lifted upward to one end of the through-pin baffle 51 is higher than the front end 31 of the guide track 3, the through-pin 2 can slide smoothly along the loading arm support surface 52 onto the guide track 3.

[0017] After the pin 2 slides onto the guide track 3, since the guide track 3 is obliquely arranged with the horizontal plane, and the front end 31 of the guide track 3 is higher than the end 32 of the guide track 3, the pin 2 can continue to move toward the end 32 of the guide track 3 under the inertia of the pulp roll 1. In order to adjust the angle between the guide track 3 and the horizontal plane and adjust the inclination of the guide track 3, the height of the rear support 7 can be adjusted. The specific structural form can be selected as follows: the rear support 7 includes a rear support frame and a support rod rotatably arranged on the rear support frame, and the rear support frame is arranged on the ground. The support rod is threadedly connected with the rear support frame, and the support rod is arranged in the vertical direction. When the support rod is rotated, the support rod moves upward or downward in the vertical direction under the action of the thread. The top of the support rod is connected to the end 32 of the guide track 3 through a spherical hinge structure, ensuring that when the rotating support rod moves upward or downward, the end 32 of the guide track 3 also moves upward or downward, thereby adjusting the angle between the guide track 3 and the horizontal plane.

[0018] After the pin 2 slides to the end 32 of the guide rail 3, it slides to the slot surface 4. The slot surface 4 is a downwardly concave groove, the left end of the groove is smoothly connected to the end 32 of the guide rail 3, and the right end of the groove is provided with a slot anti-collision pad 8, which prevents the pin 2 from jumping out of the groove and causing damage to surrounding equipment. After the pin 2 reaches the groove, it stops moving, and at this time, the feeding action is completed.
