Description

Technical Field

[0001] This utility model relates to the field of paper handle technology, and in particular to an automatic paper handle laminating machine. Background Technology

[0002] Paper handles, as a lifting aid designed specifically for items such as paper strips and packaging boxes, greatly enhance the portability and practicality of these items. Due to the limited strength of paper products themselves, in order to meet the lifting force requirements in actual use, paper handles often need to precisely bond two or more layers of paper materials together to create a stronger and more durable lifting structure.

[0003] However, in current paper handle manufacturing processes, it's easy to see that the crucial steps—from raw material sorting, gluing, bonding, to pressure holding—still largely rely on manual operation. This not only makes it difficult to achieve continuous and efficient operation throughout the production process, leading to low production efficiency, but also triggers a series of derivative problems. For example, the uncontrollability of manual operation often results in inaccurate raw material sorting, uneven gluing, insufficient bonding, and unstable pressure holding, thus affecting the overall quality and durability of the paper handle.

[0004] Furthermore, due to the limitations of manual operation, existing paper handle manufacturing plants often occupy a large area to accommodate the need for extensive manual labor. This not only increases the company's operating costs but also limits the further expansion of production scale. At the same time, the waste of raw materials during manual operation is also quite serious, and the material transfer process is cumbersome and inefficient, further driving up production costs.

[0005] Therefore, how to effectively reduce the production cost and improve the production efficiency of paper handles by improving manufacturing processes, optimizing production flow, and introducing automated equipment, while ensuring the quality and performance of paper handles, has become a key issue that needs to be addressed by those skilled in the art.

Detailed Implementation

[0037] The present invention will be further described in detail below with reference to specific embodiments:

[0038] like Figures 1-5 As shown, this utility model is applied to the production of paper handles. The paper handle is formed by bonding two layers of paper strips, which are rolls of raw material A and rolls of raw material B, respectively. The roll of raw material A is mounted on the first feeding roller 11, and the roll of raw material B is mounted on the second feeding roller 12. Speed-regulating motors are connected to the first feeding roller 11 and the second feeding roller 12 respectively to evenly feed the two raw materials. Raw material B bypasses the second guide group 12 and is conveyed within the guide flow channel 23, passing sequentially through the feeding assembly 3, the glue dispensing device 4, the bonding assembly 5, and the pressing assembly 6. Raw material A bypasses the first guide group 21 and enters the guide channel, positioned above raw material B, and sequentially passes through the bonding assembly 5 and the pressing assembly 6 to complete the bonding and pressing with raw material B. Specifically:

[0039] An automatic paper handle laminating machine includes a feeding mechanism 1 comprising a first feeding roller 11 and a second feeding roller 12 for placing raw material A and raw material B, respectively. In this embodiment, the first feeding roller 11 is positioned above the second feeding roller 12. Both raw material A and raw material B are paper materials; however, depending on actual usage requirements, paper materials can be laminated with other materials, or both can be non-paper materials. Furthermore, in other embodiments, a three-layer or multi-layer paper tape laminating setup can be used, but this requires three or more feeding rollers and two or more gluing stations.

[0040] The guiding mechanism 2 includes a first guiding group 21, a second guiding group 22, and a guiding channel 23 to guide and transport the raw materials on the first feeding roller 11 and the second feeding roller 12, respectively. The guiding channel 23 includes two symmetrically arranged guide plates 231, which are parallel to each other and form a guiding groove 232 within which the paper handle moves. In this embodiment, the two guide plates 231 are detachably connected to the frame, and their spacing can be adjusted to change the width of the guiding groove 232, thus adapting to the transport of paper handles with different width requirements.

[0041] The first guide group 21 includes a first tensioning device 211 and a plurality of first guide wheels 212. The first tensioning device 211 includes a first fixed rod 2111 and a first pressure rod 2112 parallel to and rotatably connected to the first fixed rod 2111. In this embodiment, the first fixed rod 2111 is horizontally arranged, and its two ends are rotatably connected to the frame. Raw material A passes under the first pressure rod 2112, around the first pressure rod 2112, and sequentially passes around the plurality of first guide wheels 212 into the guide channel 23. In the free state, the first pressure rod 2112 is directly below the first fixed rod 2111. When raw material A is being transported, it rubs against the first pressure rod 2112 and drives the first pressure rod 2112 to rotate along the first fixed rod 2111. Due to its own gravity, the first pressure rod 2112 tends to rotate in the opposite direction and tends to move directly below the first fixed rod 2111. At the same time, the reverse rotation tendency presses against the raw material A, thereby achieving tensioning of raw material A.

[0042] The second guide assembly 22 includes a second tensioning device 221 and multiple second guide wheels 222. The second tensioning device 221 includes a second fixed rod 2211 and a second pressure rod 2212 parallel to and rotatably connected to the second fixed rod 2211. In this embodiment, the second fixed rod 2211 is horizontally positioned and located below the first pressure rod 2112. The two ends of the first fixed rod 2111 are rotatably connected to the frame. Raw material B passes under the second pressure rod 2212, around the second pressure rod 2212, and sequentially passes around the multiple second guide wheels 222 before entering the guide channel 23. In its free state, the second pressure rod 2212 is directly below the second fixed rod 2211. When raw material B is being transported, it rubs against the second pressure rod 2212, causing the second pressure rod 2212 to rotate along the second fixed rod 2211. Due to its own gravity, the second pressure rod 2212 tends to rotate in the opposite direction and move directly below the second fixed rod 2211. At the same time, the reverse movement pushes against the raw material B, thus achieving tension on the raw material B.

[0043] The bonding mechanism includes a feeding assembly 3, a dispensing device 4, a bonding assembly 5, and a pressing assembly 6 arranged sequentially in the conveying direction of the guide channel 23.

[0044] like Figure 1 and Figure 3 As shown, the feeding assembly 3 includes a fifth pressure roller 31 disposed above the guide channel 23 and a sixth pressure roller 32 disposed below the guide channel 23, as well as a second driving device 33 capable of driving the fifth pressure roller 31 to rotate. The raw material on the second discharge roller 12 is transferred between the sixth pressure roller 32 and the fifth pressure roller 31. In this embodiment, the guide groove 232 at the first pressure roller is through-hole, and the top of the first pressure roller is parallel to or slightly higher than the bottom of the guide groove 232; the fifth pressure roller 31 and the sixth pressure roller 32 are tangentially arranged. In a preferred embodiment, a corresponding mechanism capable of driving upward and downward movement can be connected to the fifth pressure roller 31. When raw material B is fed, the fifth pressure roller 31 is driven upward to facilitate the installation of raw material B. After installation, the fifth pressure roller 31 is driven downward, pressing against the raw material B and clamping it to the sixth pressure roller 32. Then, under the drive of the second driving device 33, the raw material B is transferred. Of course, in other embodiments, a spring can also be used to press the fifth pressure roller 31 downward.

[0045] like Figure 1 and Figure 3 As shown, the dispensing device 4 is mounted on the machine base via a bracket 41. The dispensing port 42 of the dispensing device 4 is positioned within the guide groove 232, and when the raw material B is within the guide groove 232, the dispensing port 42 is slightly higher than the raw material B. In other preferred embodiments, the dispensing device 4 is inclined, meaning that one end of the dispensing port 42 is closer to the bonding component 5.

[0046] The bonding assembly 5 includes a third pressure roller 51 disposed above the guide channel 23 and a fourth pressure roller 52 disposed below the guide channel 23, as well as a third drive device 53 capable of driving the third pressure roller 51 to rotate. The upper end of the fourth pressure roller 52 penetrates the guide channel 23; the paper handle is bonded between the third pressure roller 51 and the fourth pressure roller 52. In this embodiment, raw material A passes downward around the third pressure roller 51 and is bonded to raw material B. The guide groove 232 at the fourth pressure roller 52 is through-hole, and the plane of the top end of the fourth pressure roller 52 is parallel to or slightly higher than the bottom surface of the guide groove 232; the third pressure roller 51 and the fourth pressure roller 52 are tangentially arranged. In a preferred embodiment, a corresponding mechanism capable of driving the third pressure roller 51 to move upward and downward can be connected to the third pressure roller 51. During loading, the third pressure roller 51 is lifted upwards, and raw material B and raw material A are installed together between the third pressure roller 51 and the fourth pressure roller 52. During operation, the third pressure roller 51 is driven downwards to press against raw material A, and simultaneously, driven by the third drive device 53, it comes into contact with raw material B. Of course, in other embodiments, elastic elements such as springs or counterweights can also be connected to the third pressure roller 51 to achieve downward pressure on raw material A and raw material B.

[0047] like Figure 1 and Figure 5 As shown, the pressing assembly 6 includes a first pressure roller 61 disposed above the guide channel 23, and a second pressure roller 62 whose upper end penetrates the guide channel. The first pressure roller 61 is positioned directly above the second pressure roller 62, and the paper handle is transmitted between the first pressure roller 61 and the second pressure roller 62. In this embodiment, the guide groove 232 at the second pressure roller 62 is through-hole, and the plane containing the top cut surface of the second pressure roller 62 is parallel to or slightly higher than the bottom surface of the guide groove 232. Raw materials A and B are formed into a paper handle by the bonding assembly 5, and then the paper handle is tightly connected by the first pressure roller 61 and the second pressure roller 62.

[0048] The pressing assembly 6 also includes a first base 63, a first fixing plate 64, and a second fixing plate 65 arranged sequentially in the vertical direction. A first guide rod 66 is disposed between the first base 63 and the second fixing plate 65, and the first guide rod 66 passes through the first fixing plate 64. A first driving device 67 is connected to the first pressure roller 61 and can drive it to rotate. The first driving device 67 is fixedly connected to the first fixing plate 64. The first guide rod 66 is vertically arranged, and its upper and lower ends are fixedly connected to the first base 63 and the second fixing plate 65, respectively. The first fixing plate 64 is disposed between the first base 63 and the second fixing plate 65 and is penetrated by the first guide rod 66, so that the first fixing plate 64 can slide up and down along the first guide rod 66, thereby allowing the first pressure roller 61 and the first driving device 67 to slide up and down along the first guide rod 66. The first driving device 67 can be a motor that can drive the first pressure roller 61 to rotate, or it can be other mechanisms that can drive the first pressure roller 61 to rotate.

[0049] The pressing assembly 6 is also equipped with a lever clamping device 68, which includes a clamping handle 681 mounted on the second fixed plate 65 and a second guide rod 682 connected to the clamping handle 681. The second guide rod 682 is vertically positioned, with its upper end connected to the clamping handle 681 and its lower end passing through the second fixed plate 65 and connecting to the first fixed plate 64. In this embodiment, the clamping handle 681 drives the second guide rod 682 to move vertically, thereby causing the second fixed plate 65 and the first pressure roller 61 to move vertically, facilitating the installation and clamping of the paper handle.

[0050] In this embodiment, the paper handle bonding process is as follows: the roll of raw material B is placed on the second feeding roller 12, the strip passes under the second pressure rod 2212, and then enters the guide groove 232 via multiple second guide rollers 222. In the guide groove 232, it passes sequentially between the fifth pressure roller 31 and the sixth pressure roller 32, below the glue dispensing device 4, between the third pressure roller 51 and the fourth pressure roller 52, and between the first pressure roller 61 and the second pressure roller 62.

[0051] The roll of raw material A is mounted on the first unloading roller 11. The strip passes under the first pressure bar 2112, then through multiple second guide rollers 222, and enters the guide groove 232 between the dispensing device 4 and the bonding assembly 5. After entering the guide groove 232, it is bonded to the top of raw material B; then it passes sequentially between the third pressure roller 51 and the fourth pressure roller 52, and between the first pressure roller 61 and the second pressure roller 62.

[0052] When raw material B passes through the dispensing device 4, adhesive is applied to the surface of raw material B by the dispensing device 4; when passing through the bonding component 5, raw material A and raw material B are initially bonded together under the pressure of the third pressure roller 51 to form a paper handle; when passing through the pressing component 6, the paper handle is further bonded tightly under the pressure of the first pressure roller 61.

[0053] Speed-regulating motors connected to the first feeding roller 11 and the second feeding roller 12 respectively feed raw material A and raw material B at a uniform speed. The first driving device 67 drives the first pressure roller 61 to rotate, and the third driving device 53 drives the third pressure roller 51 to rotate, thereby driving the paper handle to be transported in the guide groove 232; the second driving device 33 drives the fifth pressure roller 31 to rotate, thereby driving the raw material B to be transported.

[0054] After the paper handle is formed, a winding device can be installed in the subsequent process to wind it up; alternatively, a cutting device can be installed in the subsequent process to cut the paper handle according to its usage requirements. The processing steps after the paper handle is formed are not part of this utility model and will not be specifically described in this embodiment.

[0055] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects.
