Description

Technical Field

[0001] This utility model relates to the technical field of paper cup production equipment, specifically a paper cutting device for producing paper cups. Background Technology

[0002] In the paper cup manufacturing process, raw paper slitting is a crucial pre-processing step. A raw paper slitting device for paper cup production is a specialized piece of equipment designed to accomplish this task. This device is typically located after the unwinding mechanism and before the rewinding mechanism. Its core function is to precisely cut the continuously released raw paper longitudinally. A typical slitting device mainly includes a frame, a set of guide rollers for guiding and flattening the paper web, and the core slitting mechanism. The slitting mechanism generally employs a shearing system consisting of circular blades and a bottom blade. By adjusting the lateral position of the circular blades, the slitting width can be flexibly set, thereby simultaneously slitting wide raw paper into multiple narrow strips that meet the specifications of subsequent processes. These narrow strips are then individually wound into rolls for use in the next production stage.

[0003] In existing paper slitting devices for paper cup production, after slitting, multiple paper strips pass together through a large guide roller for overall correction and tension adjustment. This overall correction cannot cope with the deviation of individual paper strips caused by slight vibrations of the slitting blades, uneven paper material, or slight tension disturbances. Consequently, problems such as winding and uneven end faces will occur during winding, affecting the efficiency and yield of subsequent automated processes in paper cup production. In addition, the shearing action during the slitting process will cause burrs to form on the edges of the paper, making them sharp. These sharp edges can easily scratch the surface coating or the paper itself during subsequent guide roller transport and winding, affecting the waterproof performance and appearance of the paper cup.

[0004] Therefore, a paper slitting device for producing paper cups is needed to improve the above-mentioned problems. Utility Model Content

[0005] To address the problems in existing technologies, such as the inability to independently correct the deviation of individual strips of raw paper and the tendency for sharp burrs on the paper edges after slitting to cause damage, this utility model provides a raw paper slitting device for producing paper cups, thereby solving the aforementioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A paper slitting device for producing paper cups includes a support mechanism, a slitting mechanism above the support mechanism, a limit slide rail on one side of the slitting mechanism, a composite mechanism evenly arranged above the limit slide rail, and a connecting mechanism on one side of each composite mechanism; the slitting mechanism includes a slitting roller and limit seats mounted on both ends of the slitting roller above the support mechanism, and multiple slitting blades mounted around the periphery of the slitting roller; the composite mechanism includes a guide plate, a correction slider, and an edge grinding slider, correction rollers on both sides of the correction slider, and edge grinding blocks on both sides of the edge grinding slider; the connecting mechanism includes a linkage plate and clamping plates that are centrally symmetrical on both sides of the linkage plate.

[0007] Preferably, the guide plate has a correction groove and a grinding groove. The correction slider is slidably connected to the inside of the correction groove, and the grinding slider is slidably connected to the inside of the grinding groove. A spring is provided above the correction slider, and elastic ropes are connected to the upper and lower ends of the grinding slider. The other ends of the elastic ropes are connected to the inside of the grinding groove.

[0008] Preferably, the two correction rollers are symmetrical about the correction slider, and the outer side of the edge grinding block is provided with a rounded edge grinding groove.

[0009] Preferably, each side of the clamping plate is fixedly connected with a plug rod, the plug rod passes through the linkage plate, and a spring is surrounded around the plug rod.

[0010] Preferably, the bottom of the guide plate is fixedly connected to a connecting slide block, the connecting slide block is slidably connected to a limiting slide rail, and the limiting slide rail is bolted to the inner side of the support mechanism.

[0011] Preferably, a connecting rod is fixedly connected to one side of the linkage plate, and the other end of the connecting rod is fixedly connected to the bottom of the connecting slide.

[0012] Preferably, the support mechanism is provided with an unwinding mechanism and a winding mechanism at both ends.

[0013] Preferably, the inner side of the support mechanism is rotatably connected to multiple sets of guide roller mechanisms.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention, by setting up a composite mechanism and a connecting mechanism, can independently correct the deviation of each strip of paper after slitting, solving the problem that traditional devices can only correct the deviation of the entire paper web and cannot make local adjustments to a single strip of paper, thereby improving the neatness of winding and product quality.

[0015] This invention, by setting an edge grinding slider and an edge grinding block in the composite mechanism, can perform rounded grinding on the edges of the slit paper, avoiding damage to subsequent processing equipment caused by sharp edges, reducing burr problems in subsequent processing, and improving the yield of paper cup forming.

[0016] This utility model, through the linkage design of the connecting mechanism and the slitting mechanism, enables the composite mechanism to move synchronously when adjusting the spacing of the slitting blades, thereby achieving coordinated adjustment of the slitting, correction, and edge grinding stations and improving the adaptability of the composite mechanism.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] Example: Please refer to Figure 1-5 The paper slitting device for producing paper cups shown includes a support mechanism 1, a slitting mechanism 2 above the support mechanism 1, a limit slide rail 7 on one side of the slitting mechanism 2, a composite mechanism 8 evenly arranged above the limit slide rail 7, and a connecting mechanism 9 on one side of each composite mechanism 8. The slitting mechanism 2 includes a slitting roller 21 and a limiting seat 23 at both ends of the slitting roller 21 mounted on the support mechanism 1. Multiple slitting blades 22 are mounted on the periphery of the slitting roller 21. The composite mechanism 8 includes a guide plate 81, a correction slider 85, and a grinding slider 88. Correction rollers 87 are provided on both sides of the correction slider 85, and grinding blocks 89 are provided on both sides of the grinding slider 88. The connecting mechanism 9 includes a linkage plate 92 and clamping plates 93 that are centrally symmetrical on both sides of the linkage plate 92; The support mechanism 1 is equipped with a PLC controller on its outer side, which can control the operation of other equipment, which is the prior art; a cylinder 24 is installed above the limit seat 23, which can control the up and down sliding of the slitting roller 21, thereby allowing the slitting blade 22 to contact the raw paper for slitting.

[0021] In this embodiment, the guide plate 81 is provided with a correction groove 82 and a grinding groove 83. The correction slider 85 is slidably connected to the inside of the correction groove 82, and the grinding slider 88 is slidably connected to the inside of the grinding groove 83. A spring 86 is provided above the correction slider 85, and elastic ropes 881 are connected to the upper and lower ends of the grinding slider 88. The other ends of the elastic ropes 881 are connected to the inside of the grinding groove 83. Among them, spring 86 is used to apply downward pressure so that the correction rollers 87 on both sides of the correction slider 85 can closely contact the paper strip, thereby correcting the deviation; elastic rope 881 is used to suspend the edge grinding slider 88 in the middle of the edge grinding groove 83, but the distance can be adjusted up and down to fit the paper strip.

[0022] In this embodiment, the two correction rollers 87 are symmetrical about the correction slider 85, and the outer side of the grinding block 89 is provided with a rounded grinding groove 891. Among them, the correction rollers 87 between the two guide plates 81 are staggered, so the minimum distance between the two guide plates 81 is about three centimeters thick. The cross-section of the rounded corner grinding groove 891 is U-shaped, and the sandpaper is glued to the inside. The rounded corner grinding groove 891 can be divided into two areas, left and right. The left area is a transition area similar to a trumpet, and the right area is a grinding area that is straight. This allows the rounded corner grinding groove 891 to grind the edge of the paper strip and form a rounded corner.

[0023] In this embodiment, a plug rod 94 is fixedly connected to one side of the clamping plate 93. The plug rod 94 passes through the linkage plate 92, and a spring 95 surrounds the outside of the plug rod 94. Among them, the second spring 95 allows the two clamping plates 93 to move toward the linkage plate 92, thereby clamping the slitting blade 22. Thus, when the slitting blade 22 moves, the composite mechanism 8 can move synchronously through the connecting mechanism 9.

[0024] In this embodiment, a connecting slide 84 is fixedly connected to the bottom of the guide plate 81, and the connecting slide 84 is slidably connected to the limiting slide rail 7. The limiting slide rail 7 is bolted to the inner side of the support mechanism 1. The limiting slide rail 7 is parallel to the slitting roller 21 and has a groove to limit the sliding of the composite mechanism 8.

[0025] In this embodiment, a connecting rod 91 is fixedly connected to one side of the linkage plate 92, and the other end of the connecting rod 91 is fixedly connected to the bottom of the connecting slide 84; Among them, the connecting rod 91 is an inclined block used to connect the linkage plate 92 and the connecting slide 84.

[0026] In this embodiment, the support mechanism 1 is provided with an unwinding mechanism 3 and a winding mechanism 5 at its two ends, respectively; The unwinding mechanism 3 is used to loosen the original paper tube; while the winding mechanism 5 is used to wind up the cut paper strips.

[0027] In this embodiment, multiple sets of guide roller mechanisms 6 are rotatably connected to the inner side of the support mechanism 1; Among them, the guide roller mechanism 6 located on both sides of the slitting mechanism 2 has a fixed height and the bottom of the correction roller 87 is in contact with the guide roller mechanism 6, but the other guide roller mechanisms 6 can move up and down inside the support mechanism 1 to adjust the tension; the surface of the guide roller mechanism 6 has multiple raised rings for correction, which is the prior art.

[0028] The working principle of this utility model is as follows: After the raw paper is placed on the unwinding mechanism 3, it is guided by multiple guide roller mechanisms 6 on the left side, passes above the slitting mechanism 2, then passes inside the rounded edge grinding groove 891 and below the correction roller 87, and is then guided by multiple guide roller mechanisms 6 on the right side and connected to the winding mechanism 5. During this process, the spacing of multiple slitting blades 22 can be adjusted to control the slitting width. During the adjustment process, the composite mechanism 8 and the connecting mechanism 9 will also move accordingly. Finally, the slitting operation is carried out by the controller on the outside of the support mechanism 1. During the slitting process, the raw paper will be cut into multiple independent strips. These strips will be located between two composite mechanisms 8. Since each guide plate 81 is equipped with a sliding correction roller 87, the correction roller 87 can locally correct the edge of the strip. Combined with the overall correction of the existing guide roller mechanism 6, this can prevent unevenness in some areas during the winding process. In addition, since the paper strips will pass through and rub against the rounded corner grinding groove 891 in the grinding block 89 after being cut, the rounded corners on both sides of the cut paper strips can be pre-treated to reduce the subsequent processing time. During the above-mentioned adjustment of the spacing of multiple slitting blades 22, due to the flexible clamping of the clamping plate 93 on both sides of the bottom of the slitting blade 22, the connecting slide 84 and the guide plate 81 can move together through the connecting rod 91, and the movement is limited by the limiting slide rail 7, so that the composite mechanism 8 can move synchronously when the slitting blade 22 moves.

[0029] The support mechanism 1, slitting mechanism 2, unwinding mechanism 3, winding mechanism 5, and guide roller mechanism 6 used in this utility model are all existing known electrical devices, and all can be directly purchased and used on the market. Their structure, circuit, and control principle are all existing known technologies. Therefore, the structure, circuit, and control principle of the support mechanism 1, slitting mechanism 2, unwinding mechanism 3, winding mechanism 5, and guide roller mechanism 6 will not be described in detail here.

[0030] All standard parts used in this application can be purchased from the market. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art and are also general components, which are common knowledge in this field.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
