Description

Technical Field

[0001] The present invention relates to the technical field of paper laminating machines, and more particularly to a middle-section paper feeding mechanism of a paper laminating machine. Background Art

[0002] A laminating machine is primarily used to laminate two or more sheets of paper together. During laminating, the printed face paper is glued onto the bottom paper. In existing laminating machines, the face paper is fed from above by a face paper feed mechanism (e.g., a feeder), while the bottom paper is fed from below by a bottom paper feed mechanism. During this process, glue is applied to the bottom paper, and then the top face paper and bottom bottom paper are bonded together. The laminating process is then completed by a subsequent laminating mechanism.

[0003] However, some problems were found in the use of traditional paper laminating machines:

[0004] First, before the paper laminating machine starts running, it needs to be debugged first, or proofing needs to be done for a small amount of face paper and base paper. At this time, the paper conveying speed is not fast. After the paper laminating is completed, the machine needs to be stopped to check the finished product to see if the bonding is misaligned, whether the amount of glue is appropriate, etc. Secondly, when processing small batch orders, the existing paper laminating machine also needs to be fully debugged, which is not convenient. Third, when changing orders, the existing paper laminating machine needs to stop and switch the face paper size, which is also inconvenient. In response to these problems, when debugging, testing or processing small batch orders, the existing paper laminating machine needs to wait for a long time for the feeder paper feeding mechanism to deliver the face paper. If only a small amount of face paper is processed, the height of the face paper material table needs to be adjusted to cooperate with the feeder paper feeding. This results in a lot of time wasted on face paper delivery during debugging and testing, which greatly affects the efficiency of debugging and testing, and also affects the overall work efficiency. At the same time, if the traditional feeder paper feeding mechanism needs to change orders (i.e. process facial tissue of another size), it is necessary to stop the machine after feeding the facial tissue on the previous batch of facial tissue material table, and then change orders, which cannot be processed continuously and efficiently. Summary of the Invention

[0005] In response to the shortcomings of the existing technology, the present invention provides a paper mounting machine. By setting a paper feeding gap, surface paper can be quickly transported from the paper feeding gap, which facilitates the debugging and proofing of the equipment. At the same time, when it is necessary to change orders, it can be switched to feeding paper through the paper feeding gap, and then the size of the feeder paper feeding mechanism can be adjusted. By switching the paper feeding method, the machine can be kept running, thereby improving the efficiency of proofing and changing orders.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a paper mounting machine, comprising a face paper feeding mechanism, a face paper conveying mechanism and a bottom paper conveying mechanism, wherein the face paper feeding mechanism or the face paper conveying mechanism is arranged transversely and a paper feeding gap is formed at the transverse portion, and a paper feeding platform is provided to one side of the paper feeding gap, and the paper feeding platform is used to carry face paper, and a paper feeding roller is provided on the paper feeding platform, and the paper feeding roller drives the face paper to enter the face paper feeding mechanism or the face paper conveying mechanism from the paper feeding gap.

[0012] The present invention is further configured such that: a guiding slope is provided at one end of the first conveying frame close to the paper feeding gap, and the guiding slope is arranged to be inclined from top to bottom along the surface paper conveying direction.

DETAILED DESCRIPTION

[0030] The present invention will be further described in detail below with reference to the accompanying drawings.

[0031] This embodiment discloses a paper mounting machine, such as Figure 1-9 As shown, it includes a face paper feeding mechanism 1, a face paper conveying mechanism 2 and a bottom paper conveying mechanism 13, wherein the face paper feeding mechanism 1 is connected to a feeder feeding mechanism (not shown in the figure) (the feeder feeding mechanism is the same as that in the prior art), which is arranged in a frame 14 and conveys the face paper sheets to the face paper conveying mechanism 2 one by one through the feeder feeding mechanism 13. Figure 2, a conveyor belt is provided at the bottom, and the bottommost bottom paper is transported out each time by the conveyor belt, and then the gluing and pressing mechanism are used to complete the paper mounting work. The characteristic of this embodiment is that the facial paper conveying mechanism 2 or the facial paper feeding mechanism 1 is arranged in a transverse direction and a paper feeding gap 3 is formed at the transverse direction. The paper feeding gap 3 is extended to one side to form a paper feeding platform 4. The paper feeding platform 4 is used to carry facial paper. A paper feeding roller 41 is provided on the paper feeding platform 4. The paper feeding roller 41 drives the facial paper from the paper feeding gap 3 into the facial paper conveying mechanism 2. According to the different positions of the paper feeding gap, the present invention has two embodiments: Embodiment 1 is as follows: Figure 1 , the paper feeding gap 3 is set at the surface paper conveying mechanism 2. Example 2 Figure 8 The paper feeding gap 3 is arranged at the surface paper feeding mechanism 2. Among them, embodiment 1 is preferred, and the specific structure of embodiment 1 is described in detail below.

[0032] Reference Figure 2-3 The paper feeding gap 3 is directly set on the conveyor frame 21 and extends out of the paper feeding platform 4. In conjunction with the paper feeding roller 41, the facial paper can be directly fed into the facial paper conveying mechanism 2, so that the facial paper can immediately be laminated with the bottom paper below, greatly shortening the waiting time for facial paper delivery. It can quickly check whether the finished laminated paper meets the requirements and adjust parameters in time, such as whether the speeds of the facial paper conveying mechanism 2 and the bottom paper conveying mechanism 13 match, whether the laminated paper is offset or misaligned on the bottom paper, whether the amount of glue is appropriate, etc., saving the waiting time of traditional laminating machines during debugging and testing, and greatly improving work efficiency. In addition, during the laminating process, if the original feeder paper feeding mechanism has finished feeding facial paper, it can be switched to feeding facial paper through the paper feeding gap. During this process, the facial paper material table of the feeder paper feeding mechanism can be reloaded, achieving the effect of laminating without stopping the machine. To expand further, if small batches of paper mounting are carried out, the face paper can also be fed directly from the paper feeding gap, saving the debugging time of the feeder paper feeding mechanism. When large batches of paper mounting are carried out, the feeder paper feeding mechanism can be used to automatically transport the face paper, which also increases the versatility of the equipment. According to various needs, the two different face paper feeding methods can be flexibly switched.

[0033] Further, refer to Figure 1-2 As a preferred embodiment of the first embodiment, the conveyor frame 21 is configured as two disconnected parts, including a first conveyor frame 211 and a second conveyor frame 212, with a paper feed gap 3 formed between the first conveyor frame 211 and the second conveyor frame 212. By providing the disconnected first conveyor frame 211 and the second conveyor frame 212, the spacing position between the first conveyor frame 211 and the second conveyor frame 212 can be better adjusted, thereby adjusting the formed paper feed gap 3 to accommodate different thicknesses of facial paper.

[0034] Further, refer to Figure 2A first pressure roller 81, a second pressure roller 82, and a third pressure roller 83 are disposed above the conveyor frame 21. The first pressure roller 81 is disposed at the entrance of the tissue paper conveying mechanism 2, the second pressure roller 82 is disposed at the exit of the paper feeding gap 3, and the third pressure roller 83 is disposed at the exit of the tissue paper conveying mechanism 2. A plurality of first conveying ropes 9 are wound around the first pressure roller 81, the second pressure roller 82, and the third pressure roller 83. With the above structure, tissue paper fed through the tissue paper feeding mechanism 1 is engaged by the first pressure roller 81, tissue paper fed from the paper feeding gap 3 is engaged by the second pressure roller 82, and tissue paper is engaged by the third pressure roller 83 when being delivered. Together with the wound first conveying ropes, the first conveying ropes 9 clamp the tissue paper to the corresponding conveying ropes on the conveyor frame 2, ensuring smooth tissue paper transportation. Stable transportation of tissue paper is achieved both when entering and leaving the conveyor frame 2.

[0035] Further, refer to Figure 3 A connecting plate 10 is provided in the paper feeding gap 3. One end of the connecting plate 10 is connected to the paper feeding roller 41, and the other end is connected to the facial paper conveying mechanism 2. A bevel portion 101 is provided at the end of the connecting plate 10 corresponding to the paper feeding roller 41. The bevel portion 101 is arranged to be inclined from bottom to top along the facial paper conveying direction. Because facial paper is thin, if the paper is fed by the paper feeding roller 41 instead of a feeder, as the paper feeding roller 41 rotates, the facial paper is easily sucked onto the paper feeding roller 41 and moves downward along the conveying roller 41, causing a paper jam. Therefore, the provision of the connecting plate 10 can effectively avoid paper jams, especially since the bevel portion 101 is provided at the end near the paper feeding roller 41, which can correctly guide the facial paper into the facial paper conveying mechanism 2.

[0036] In order to further ensure the delivery of facial paper, refer to Figure 5 A pressure roller 5 is provided above the conveyor frame 21 near the paper feeding gap 3. The pressure roller 5 may be provided with an elastic structure such as a torsion spring to maintain contact with the paper feeding roller 41. By providing the pressure roller 5 to clamp the facial paper, the power for feeding the facial paper is increased, and the friction between the stacked papers that may cause the facial paper to be unable to be fed out is avoided.

[0037] Further, refer to Figure 3 The first conveying frame 211 is provided with a guide slope 7 at one end near the paper feeding gap 3, and the guide slope 7 is arranged to be inclined from top to bottom along the paper feeding direction. By setting the guide slope 7, the paper is guided so that it can be smoothly fed out of the paper feeding gap 3.

[0038] Further, refer to Figure 5-6, a plurality of second conveying ropes 6 that can carry facial paper are wound around the second conveying frame 21, and a rope loop groove 411 is provided on the paper feeding roller 41, and at least one of the plurality of second conveying ropes 6 is wound around the rope loop groove 411. At the same time, the servo motor that controls the rotation of the paper feeding roller 41 is consistent with the speed of the second conveying rope 6. Through the setting of the second conveying rope 6, the second conveying rope 6 can directly contact the facial paper, thereby better carrying the facial paper. As a preferred embodiment, the second conveying rope 6 is arranged below the first conveying rope 9, and the second conveying rope 6 and the first conveying rope 9 are staggered so that the second conveying rope 6 can carry the facial paper and transport it between the first conveying rope 9 and the second conveying rope 6. In this way, the facial paper can be clamped by the elasticity of the first conveying rope 9 and the second conveying rope 6, thereby improving the conveying reliability.

[0039] Furthermore, the facial paper conveying mechanism 2 is provided with an outer baffle 11 at a position corresponding to the paper feed gap 3. The outer baffle 11 is disposed above the conveying frame 21 and is tilted along the direction of facial paper conveyance. The outer baffle 11 further blocks the facial paper being fed from the paper feed gap 3, ensuring that even hard facial paper is better guided along the conveyance direction.

[0040] The specific structure of Example 2 is shown in FIG. Figure 9 The paper feeding platform 4 includes a conveyor plate extending at an angle. Several pressure rollers are installed on the conveyor plate to ensure smooth paper feeding. Feed rollers 41 are located at both the front and rear ends of the conveyor plate to provide power for paper feeding. A rotating roller 15, which provides auxiliary power, is located above the middle section of the conveyor plate. This rotating roller 15 simultaneously acts on the passageway of the facial paper feed mechanism 1 above it and the conveyor plate below it. When using a feeder for paper feeding, the rotating roller 15 can provide power for the facial paper feed mechanism 1. When using a paper gap for paper feeding, it can also provide a certain amount of power for the paper feeding platform 4. Furthermore, a connecting plate 10 and an inclined portion 101 are also located near the paper feed roller 41 of the facial paper feed mechanism 1 to guide the facial paper.

[0041] The paper feeding platform 4 of the embodiment 1 and the embodiment 2 is further provided with a pair of slidable paper baffles 42. Figure 7 The paper stopper 42 is slidably adjusted laterally by the slots provided on the paper feeding platform 4. The spacing of the paper stopper 42 can be adjusted according to the size of the facial paper to ensure the neatness of the facial paper.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
