Description

Technical Field

[0001] This utility model relates to the field of paper drum production technology, and in particular to a drum rolling machine for paper drum production. Background Technology

[0002] The body of the packaging paper drum is made of kraft paper bonded with polyvinyl alcohol solution. The production of paper drums often requires the use of a drum rolling machine. Common paper drums need a certain clamping structure during the drum rolling operation to improve the stability of the finished product quality. At the same time, it is also necessary to facilitate the unloading of the drum after the drum rolling operation to improve the working efficiency of the drum rolling machine.

[0003] A search revealed that utility model patent CN222223600U discloses a winding machine for paper drum production, comprising a winding mechanism, a pressing mechanism fixedly connected to one side of the upper part of the winding mechanism, a cutting mechanism fixedly connected to one side of the pressing mechanism, and an adhesive applicator fixedly connected to the other side of the upper part of the winding mechanism. The winding mechanism includes a base, a winding bracket fixedly connected to one side of the upper part of the base, a winding motor fixedly connected to the outer side of the winding bracket, a sliding groove embedded in the top of the base, and a first electric telescopic component fixedly connected to the other side of the upper part of the base.

[0004] Although the aforementioned roll-up machine can roll kraft paper drums, after the roll-up is completed and the kraft paper is cut using the cutting mechanism, the end of the kraft paper will be located inside the cutting opening and blocked by the cutting bracket. When manually pulling it later, it will be very inconvenient due to the obstruction of the cutting bracket, thus increasing the difficulty of roll-up.

[0005] Therefore, it is necessary to invent a drum rolling machine for paper drum production to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a roll-up machine for paper drum production, which avoids obstructing the kraft paper after it has been cut, thus making it easier to pull the end of the kraft paper during subsequent roll-up. This reduces operational difficulty and improves roll-up efficiency, making it more convenient in actual use. This solves the problem mentioned in the background art where, after roll-up and cutting of the kraft paper by the cutting mechanism, the end of the kraft paper is located inside the cutting opening and is blocked by the cutting bracket. Subsequent manual pulling of the kraft paper is very inconvenient due to the obstruction of the cutting bracket, thus increasing the difficulty of roll-up.

[0007] According to one aspect of this disclosure, a rolling machine for paper drum production is provided, comprising:

[0008] A frame for suspending rolls of kraft paper;

[0009] A roll-up mechanism for winding kraft paper into a roll; and

[0010] An open-type cutting mechanism, comprising a first U-shaped frame, a clearance groove, a reciprocating screw, a second motor, a slider, a guide rod, a cutting blade, and a pressure wheel;

[0011] The first U-shaped frame is fixedly installed between the L-shaped frame and the adjacent support rod. The clearance groove is opened on the inner side of the first U-shaped frame. The reciprocating screw is rotatably nested on the inner side of the first U-shaped frame through a bearing. The second motor is fixedly installed at the right end of the first U-shaped frame and is connected to the reciprocating screw for transmission. The slider is sleeved on the outer side of the reciprocating screw. The guide rod slides through the slider and is fixedly installed on the inner side of the first U-shaped frame. The second U-shaped frame is fixedly installed at the bottom end of the slider. The cutting blade is fixedly installed in the middle of the inner side of the second U-shaped frame. Two pressure wheels are provided and are rotatably installed at both ends of the inner side of the second U-shaped frame through a pin.

[0012] A paper drum rolling machine according to at least one embodiment of the present disclosure includes a base plate and an L-shaped frame, the L-shaped frame being fixedly disposed on the top left side of the base plate.

[0013] According to at least one embodiment of the present disclosure, a paper drum rolling machine for paper drum production includes a frame further comprising a suspension frame and support rods. The suspension frame is fixedly disposed on the top inner side of the L-shaped frame, and two support rods are provided, both of which are fixedly disposed on the top right end of the base plate. Both support rods are fixedly connected to the L-shaped frame.

[0014] According to at least one embodiment of the present disclosure, a paper drum rolling machine for paper drum production includes a rotating tube, a hollow drum, and an air pump connecting pipe. The rotating tube passes through an L-shaped frame and is rotatably connected to the L-shaped frame via a bearing. The hollow drum is fixedly connected to the right end of the rotating tube and has a plurality of air holes evenly distributed on its surface. The air pump connecting pipe is connected to the left end of the rotating tube via a rotary joint.

[0015] According to at least one embodiment of the present disclosure, a paper drum rolling machine for paper drum production includes a first motor and gears. The first motor is fixedly disposed on the left side of the L-shaped frame. Two gears are provided and mesh with each other. One gear is drivenly connected to the first motor, and the other gear is fixedly sleeved on the outside of the rotating tube.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] This invention features an open cutting mechanism. After the roll is completed, the second motor drives the reciprocating screw to rotate. As the screw rotates, it causes the slider, guided by the guide rod, to move continuously to the right. During this movement, the slider moves synchronously to the right via the second U-shaped frame, driving the cutting blade and the pressure roller. As the cutting blade and pressure roller move, the two pressure rollers press the kraft paper against the inner wall of the first U-shaped frame. Simultaneously, the cutting blade cuts the pressed kraft paper. Subsequently, as the reciprocating screw continues to rotate, the slider eventually returns to its original position, at which point the second motor is stopped. The unobstructed end of the kraft paper can then be pulled directly from the inside of the first U-shaped frame. Compared to existing technologies, this invention avoids obstructing the kraft paper after cutting, making it easier to pull the end of the kraft paper during subsequent roll-up. This reduces operational difficulty and improves roll-up efficiency, making it more convenient in actual use. Attached Figure Description

[0026] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0027] Figure 1 This is a schematic diagram of the overall structure of a paper drum rolling machine according to one embodiment of the present disclosure.

[0028] Figure 2 This is a schematic diagram of the frame 1 and the winding mechanism 2 of a paper drum production machine according to one embodiment of the present disclosure.

[0029] Figure 3 This is a schematic diagram of the open cutting mechanism 3 of a paper drum production rolling machine according to one embodiment of the present disclosure.

[0030] like Figures 1-3 As shown, the paper drum rolling machine disclosed herein may include components such as a frame 1, a rolling mechanism 2, and an open cutting mechanism 3.

[0031] like Figure 2 As shown in this disclosure, the frame 1 includes a base plate 11, an L-shaped frame 12, a suspension frame 13, and support rods 14. The L-shaped frame 12 is fixedly installed on the top left side of the base plate 11, the suspension frame 13 is fixedly installed on the top inner side of the L-shaped frame 12, and there are two support rods 14, both of which are fixedly installed on the top right end of the base plate 11. Both support rods 14 are fixedly connected to the L-shaped frame 12.

[0032] This allows for the use of the suspension frame 13 to suspend the rolls of kraft paper, facilitating subsequent traction and winding.

[0033] like Figure 2As shown, in a preferred embodiment, the winding mechanism 2 includes a rotating tube 21, a hollow drum 22, an air pump connecting pipe 23, a first motor 24, and gears 25. The rotating tube 21 passes through the L-shaped frame 12 and is rotatably connected to the L-shaped frame 12 via bearings. The hollow drum 22 is fixedly connected to the right end of the rotating tube 21 and has multiple air holes evenly distributed on its surface. The air pump connecting pipe 23 is connected to the left end of the rotating tube 21 via a rotary joint. The first motor 24 is fixedly disposed on the left side of the L-shaped frame 12. There are two gears 25 that mesh with each other. One gear 25 is connected to the first motor 24 for transmission, and the other gear 25 is fixedly sleeved on the outside of the rotating tube 21.

[0034] Therefore, in order to attach the end of the kraft paper to the outside of the hollow roll 22, the air pump connected to the air pump connection pipe 23 draws air from inside the hollow roll 22 through the air pump connection pipe 23 and the rotating pipe 21, so that the end of the kraft paper is attached to the surface of the hollow roll 22 due to negative pressure. Then, the first motor 24 drives the rotating pipe 21 to rotate through the gear 25. When the rotating pipe 21 rotates, it drives the hollow roll 22 to wind the kraft paper. During the winding process, glue is continuously applied to the surface of the kraft paper until multiple layers of kraft paper are bonded together to form a paper drum.

[0035] like Figure 3 As shown in this disclosure, the open cutting mechanism 3 includes a first U-shaped frame 31, a clearance groove 32, a reciprocating screw 33, a second motor 34, a slider 35, a guide rod 36, a second U-shaped frame 37, a cutting blade 38, and a pressure wheel 39. The first U-shaped frame 31 is fixedly disposed between the L-shaped frame 12 and the adjacent support rod 14. The clearance groove 32 is formed inside the first U-shaped frame 31. The reciprocating screw 33 is rotatably nested inside the first U-shaped frame 31 via a bearing. Two motors 34 are fixedly mounted on the right end of the first U-shaped frame 31 and are connected to the reciprocating screw 33 for transmission. The slider 35 is driven and sleeved on the outside of the reciprocating screw 33. The guide rod 36 slides through the slider 35 and is fixedly mounted on the inside of the first U-shaped frame 31. The second U-shaped frame 37 is fixedly mounted on the bottom end of the slider 35. The cutting blade 38 is fixedly mounted on the middle of the inside of the second U-shaped frame 37. Two pressure wheels 39 are provided and are rotatably mounted on both ends of the inside of the second U-shaped frame 37 via pins.

[0036] Therefore, after the roll is completed, the second motor 34 drives the reciprocating screw 33 to rotate. When the reciprocating screw 33 rotates, it drives the slider 35, which is guided by the guide rod 36, to move continuously to the right. During the rightward movement of the slider 35, the cutting blade 38 and the pressure roller 39 move synchronously to the right through the second U-shaped frame 37. As the cutting blade 38 and the pressure roller 39 move continuously, the two pressure rollers 39 press the kraft paper against the inner wall of the first U-shaped frame 31. At the same time, the cutting blade 38 cuts the pressed kraft paper. Subsequently, as the reciprocating screw 33 continues to rotate, the slider 35 eventually returns to its original position. At this time, the second motor 34 is stopped. Afterward, the unobstructed end of the kraft paper can be pulled directly from the inside of the first U-shaped frame 31. Compared with the existing technology, this avoids obstruction after the kraft paper is cut, making it easier to pull the end of the kraft paper during subsequent roll-up. This reduces the difficulty of operation and improves the efficiency of roll-up, making it more convenient in actual use.

[0037] It should also be noted that any content not described in detail in this specification is prior art known to those skilled in the art.

[0038] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure. Those skilled in the art can make other changes or modifications based on the above disclosure, and these changes or modifications still fall within the scope of the present disclosure.
