Description

Technical Field

[0001] This invention relates to a miniaturized honeycomb paper machine. Background Technology

[0002] Most honeycomb paper machines on the market are large in size and heavy in weight, resulting in poor flexibility of use. Some smaller honeycomb paper machines are compatible with honeycomb paper consumables with smaller roll diameters and do not have a cutting module, requiring manual tearing of the honeycomb paper, which leads to a poor user experience. In addition, most honeycomb paper machines on the market use the speed difference between two pairs of rubber rollers to stretch and unfold the honeycomb paper, which is relatively expensive.

[0003] Therefore, overcoming the aforementioned technical deficiencies is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] The purpose of this invention is to provide a miniaturized honeycomb paper machine to solve at least one of the above-mentioned technical problems.

[0005] According to one aspect of the present invention, a miniaturized honeycomb paper machine is provided, comprising:

[0006] Rotatable paper feed roller;

[0007] A pair of output rollers rotating in opposite directions, with the output rollers rotating at a speed greater than that of the feed rollers;

[0008] The support rod is used to carry the honeycomb paper roll. When the honeycomb paper roll is supported on the support rod, the bottom of the honeycomb paper roll can press against the feed roller. The speed difference between the output roller and the feed roller can unfold the honeycomb paper fed from the honeycomb paper roll into a three-dimensional shape; and

[0009] The pressure mechanism drives the support rod to maintain a tendency to move towards the paper feed roller so that the bottom of the honeycomb paper roll carried on the support rod is in close contact with the paper feed roller.

[0010] The miniaturized honeycomb paper machine of this invention, when producing honeycomb paper for packaging items, involves placing a honeycomb paper roll onto a support rod, with the bottom of the roll pressing against a feeding roller. When a drive device (such as a motor) drives the feeding roller and the output roller to rotate, the speed difference between the output roller and the feeding roller allows the honeycomb paper roll to unfold into a three-dimensional shape. This three-dimensional honeycomb paper can be used for packaging items. Because the pressure mechanism can drive the support rod to maintain a tendency to move towards the feeding roller, the bottom of the honeycomb paper roll on the support rod is kept close to the feeding roller. The pressure applied to the support rod by the pressure mechanism ensures stable paper feeding by the feeding roller and prevents... When the paper feed roller vibrates during the paper feeding process, especially when the honeycomb paper roll is unwound to a small diameter, the miniaturized honeycomb paper machine of this invention no longer requires two pairs of rubber rollers when the honeycomb paper is stretched and unfolded. The paper feed roller is a single roller, which simplifies the structure, reduces costs, and reduces size and weight. In addition, since the support rod maintains a tendency to move towards the paper feed roller during the unwinding process of the honeycomb paper roll and the bottom of the honeycomb paper roll is always pressed against the paper feed roller, the honeycomb paper roll and the single-roll paper feed roller are in a close fit state, and no gap needs to be reserved. Thus, the device of this invention can be compatible with honeycomb paper consumables with larger roll diameters while maintaining a size similar to that of honeycomb paper machines on the market.

[0011] In some embodiments, a support frame may also be included. The pressure mechanism may include a rotating pressure plate and a first tensioning member. One end of the rotating pressure plate is hinged to the support frame, one end of the first tensioning member is disposed on the support frame, and the other end of the first tensioning member is disposed on the rotating pressure plate. The other end of the rotating pressure plate can press against the bearing rod. The first tensioning member can drive the rotating pressure plate to apply pressure to the bearing rod so that the bottom of the honeycomb paper roll carried on the bearing rod is in close contact with the paper feed roller.

[0012] Therefore, since the rotating pressure plate can rotate on the support frame, under the tension of the first tensioning component, the rotating pressure plate can always press against the bearing rod, apply pressure to the bearing rod, ensure that the bottom of the honeycomb paper roll on the bearing rod is always in close contact with the paper feed roller, ensure stable paper feeding by the paper feed roller, and prevent slippage between the honeycomb paper and the paper feed roller when the honeycomb paper roll is unwound to a small diameter.

[0013] In some embodiments, the support frame may be provided with a receiving groove, in which the end of the bearing rod is received.

[0014] When the rotating pressure plate applies pressure to the support rod, the support rod can move in the receiving groove so that the bottom of the honeycomb paper roll supported on the support rod is in close contact with the paper feed roller.

[0015] Therefore, during the unwinding process, as the unwinding radius decreases, the support rod moves towards the feed roller in the receiving groove. At the same time, under the pressure applied by the rotating pressure plate, the bottom of the honeycomb paper roll supported on the support rod remains in close contact with the feed roller, ensuring stable paper feeding by the feed roller and preventing slippage between the honeycomb paper and the feed roller when the honeycomb paper roll is unwound to a small diameter.

[0016] In some embodiments, the pressure mechanism may further include a limiting plate and a second tensioning component. The limiting plate is hinged to the support frame, one end of the second tensioning component is disposed on the support frame, and the other end of the second tensioning component is disposed on one end of the limiting plate. The other end of the limiting plate is provided with a slot, and the side of the limiting plate near the receiving slot is provided with an arc-shaped edge.

[0017] The rotating pressure plate is equipped with a first pin.

[0018] When the rotating pressure plate and the limiting plate are in their initial state, the first pin is engaged in the slot.

[0019] When the bearing rod is housed in the receiving groove and presses against the arc-shaped edge of the limiting plate, the bearing rod drives the limiting plate to swing so that the first pin disengages from the slot and the rotating pressure plate presses against the bearing rod.

[0020] When the rotating pressure plate and the limiting plate are in the final state, the arc-shaped edge of the limiting plate presses against the first pin and the rotating pressure plate presses against the bearing rod.

[0021] Therefore, before the support rod carrying the honeycomb paper roll is placed in the receiving slot of the support frame, the rotating pressure plate and the limiting plate are in their initial state. At this time, the first pin on the rotating pressure plate is engaged in the slot on the limiting plate (the rotating pressure plate and the limiting plate are locked together), facilitating feeding. Then, the support rod carrying the honeycomb paper roll is placed in the receiving slot on the support frame. Under the action of gravity, the support rod will press against the arc-shaped edge of the limiting plate, thereby driving the limiting plate to swing on the support frame. At this time, the first pin on the rotating pressure plate will disengage from the slot on the limiting plate (the rotating pressure plate and the limiting plate are unlocked). Under the pulling force of the first tensioning component, the rotating pressure plate swings on the support frame and presses against the support rod. The rotating pressure plate applies pressure to the support rod, ensuring that the bottom of the honeycomb paper roll carried on the support rod is tightly attached to the paper feeding roller, making the paper feeding roller stable. When the rotating pressure plate and the limiting plate... When the board is in the final stage, i.e., when the honeycomb paper roll is unwound to its smallest diameter, under the tension of the second tensioning component, the arc-shaped edge of the limiting plate presses against the first pin. Under the tension of the first tensioning component, the rotating pressure plate presses against the carrying rod. Thus, under the dual pressure of the limiting plate and the rotating pressure plate, the bottom of the small-diameter honeycomb paper roll is ensured to be firmly attached to the paper feed roller, preventing the paper feed roller from jumping or the honeycomb paper from slipping on the paper feed roller. The arc-shaped edge design on the limiting plate ensures that when the carrying rod is placed in the receiving groove on the support frame, the limiting plate will swing under the weight of the support rod and the honeycomb paper roll, thereby causing the first pin on the rotating pressure plate to disengage from the slot on the limiting plate, unlocking the rotating pressure plate and the limiting plate. Moreover, the arc-shaped edge on the limiting plate allows the carrying rod to move smoothly and steadily towards the paper feed roller in the receiving groove on the support frame.

[0022] In some embodiments, a second pin may be provided on the support frame, which can limit the swing range of the rotating pressure plate.

[0023] When the rotating pressure plate abuts against the second pin, the first pin will not cross the end of the limiting plate with a slot so that the first pin will not disengage from the slot.

[0024] Therefore, when the honeycomb paper roll is unwound, the support rod needs to be removed and the rotating pressure plate lifted. The second pin can limit the lifting angle range of the rotating pressure plate. When the rotating pressure plate is lifted to abut against the second pin, the first pin on the rotating pressure plate is once again engaged in the slot on the limiting plate, realizing the interlocking of the rotating pressure plate and the limiting plate. The rotating pressure plate and the limiting plate return to their initial state. At this time, the support rod can be removed from the receiving slot on the support frame for easy unloading. The second pin can prevent the rotating pressure plate from swinging too much when it is lifted, causing the first pin on the rotating pressure plate to cross the end of the limiting plate with the slot. This would result in the rotating pressure plate and the limiting plate not being able to return to their initial state when loading the next batch of material. Under the pulling force of the second tensioning component, the limiting plate would block the opening of the receiving slot on the support frame, making it impossible to load the material, that is, the support rod carrying the honeycomb paper roll cannot be placed in the receiving slot on the support frame.

[0025] In some embodiments, both the first tensioning member and the second tensioning member are tension springs.

[0026] Therefore, during the unwinding process, the honeycomb paper roll on the support rod is pressed against the bearing rod by the tension of the tension spring. The rotating pressure plate applies pressure to the bearing rod, making the bottom of the honeycomb paper roll on the bearing rod stick tightly to the paper feed roller. During the unwinding process, under the tension of the tension spring, the arc-shaped edge of the limiting plate can stick tightly to the bearing rod in the receiving groove, so that the bearing rod can move smoothly and steadily towards the paper feed roller in the receiving groove on the support frame. In addition, when the rotating pressure plate and the limiting plate are in the finishing state, that is, when the honeycomb paper roll is unwound to the smallest roll diameter, under the tension of the tension spring, the arc-shaped edge of the limiting plate can be firmly pressed against the first pin.

[0027] In some implementations, the number of support frames and pressure mechanisms can both be two.

[0028] One pressure mechanism is mounted on one support frame, another pressure mechanism is mounted on another support frame, and the paper feed roller is located between the two support frames.

[0029] The two ends of the support rod are respectively housed in receiving slots on two support frames.

[0030] Therefore, the two support frames can provide support for the support rod and the honeycomb paper roll on the support rod, and the two pressure mechanisms can simultaneously apply pressure to both ends of the support rod, so that the honeycomb paper roll on the support rod is in close contact with the paper feed roller in the width direction, ensuring stable unwinding of the honeycomb paper roll.

[0031] In some embodiments, an arc-shaped base plate may also be included.

[0032] The paper feed roller has multiple rings arranged along its length.

[0033] The base plate has multiple perforations.

[0034] The ring on the paper feed roller is inserted upwards through a hole in the bottom plate, and the top of the ring extends out from the upper surface of the bottom plate.

[0035] The pressure mechanism drives the support rod to maintain a tendency to move towards the paper feed roller so that the bottom of the honeycomb paper roll carried on the support rod is in close contact with the ring on the paper feed roller.

[0036] Therefore, by having multiple rings closely adhere to the bottom of the honeycomb paper roll, the friction between the two can be increased, further preventing slippage between the honeycomb paper and the feed roller when the honeycomb paper roll is unwound to a small diameter. Moreover, the arc-shaped bottom plate can guide the unwinding of the honeycomb paper roll, reducing the risk of the honeycomb paper being stuck before entering the output roller. In addition, the bottom plate can also collect paper scraps, catching some of the paper scraps generated during the unwinding process due to stretching of the honeycomb paper roll.

[0037] In some embodiments, a rotatable guide roller may also be included, located on the side of the base plate, so that the honeycomb paper roll carried on the support rod can bypass the guide roller and enter between the two output rollers.

[0038] Therefore, the guide roller can make the honeycomb paper roll carried on the support rod enter the two output rollers more smoothly and steadily.

[0039] In some embodiments, a cutter module may also be included, which is located downstream of the paper output roller.

[0040] The cutting module includes a drive unit, a timing belt, a cutter, a cutter holder, and a fixed blade. The drive unit drives the timing belt for transmission. The cutter is mounted on the cutter holder, which is located on the timing belt. The fixed blade is arranged parallel to the paper output roller, and the cutter is attached to the fixed blade.

[0041] When the drive unit drives the synchronous belt to convey the paper, the synchronous belt drives the cutter holder to move back and forth so that the cutter cuts the three-dimensional honeycomb paper sent out by the paper roller.

[0042] Therefore, when it is necessary to cut the three-dimensional honeycomb paper sent out by the paper output roller, the drive unit drives the synchronous belt to move back and forth. The synchronous belt drives the knife holder to move back and forth. The knife holder drives the cutter to move back and forth. Since the cutter is attached to the fixed knife, under the cooperation of the cutter and the fixed knife, the cutter cuts the three-dimensional honeycomb paper sent out by the paper output roller.

[0043] In some embodiments, the cutter module may further include a slide, a first gear, a second gear, a connecting shaft, and a rack.

[0044] The slide is mounted on the synchronous belt. Both the first and second gears are mounted on the slide and can rotate on it. The first gear meshes with the rack, and the second gear meshes with the first gear. The second gear is connected to the knife holder via a connecting shaft, which in turn drives the knife holder to rotate. The rack is arranged parallel to the paper output roller.

[0045] When the synchronous belt drives the slide to move back and forth along the rack, the second gear drives the knife holder to rotate so that the rotating cutter on the knife holder cuts out the three-dimensional honeycomb paper fed out by the paper roller.

[0046] Therefore, when it is necessary to cut the three-dimensional honeycomb paper sent out by the paper output roller, the drive component drives the synchronous belt to move. The synchronous belt drives the slide to move. The first gear on the slide rolls along the rack. The first gear drives the second gear to rotate. The second gear drives the knife holder to rotate through the connecting shaft. The knife holder drives the cutter to rotate. The cutter moves along the length of the rack while rotating. The rotating cutter, in cooperation with the fixed knife, cuts the three-dimensional honeycomb paper sent out by the paper output roller.

[0047] In some embodiments, the cutter module may also include a tension spring and a retaining spring. The end of the cutter holder is provided with a conical boss. The cutter is circular. The retaining spring is sleeved on the cutter holder and fixedly connected to the cutter holder. The cutter is sleeved on the cutter holder and can move on the cutter holder along the axial direction of the cutter holder. The cutter is located between the retaining spring and the conical boss. The tension spring is placed on the conical surface of the conical boss. The tension spring drives the cutter to move towards the retaining spring so that the cutter fits against the fixed blade.

[0048] Therefore, under the restoring force of the tension spring, the cutter tends to move towards the retaining spring, which allows the cutter to remain in contact with the fixed blade during the cutting of the honeycomb paper. At the same time, the cutter has a certain floating space along the axial direction of the blade holder, thus ensuring that the cutter and the fixed blade do not produce abnormal noise while cutting the honeycomb paper.

[0049] In some embodiments, a handle may also be included, which is disposed on the slide.

[0050] When the handle is turned, it causes the slide to move back and forth along the rack.

[0051] Therefore, when it is necessary to cut the three-dimensional honeycomb paper sent out by the paper output roller, electric cutting can be performed without the use of a drive component. The handle can be moved along the length of the rack, the handle drives the slide to move along the length of the rack, the first gear on the slide rolls along the rack, the first gear drives the second gear to rotate, the second gear drives the knife holder to rotate through the connecting shaft, the knife holder drives the cutter to rotate, and the cutter rotates while moving along the length of the rack. The rotating cutter, in cooperation with the fixed knife, cuts the three-dimensional honeycomb paper sent out by the paper output roller, realizing manual cutting. The miniaturized honeycomb paper machine of the present invention can be compatible with manual / electric cutting of honeycomb paper.

[0052] In some embodiments, a guide rail may also be included, which is arranged parallel to the paper output roller, and a slide block is slidably mounted on the guide rail.

[0053] As a result, the slide can move smoothly along the guide rail, ensuring that the cutter can smoothly cut the three-dimensional honeycomb paper sent out by the paper output roller. Attached Figure Description

[0067] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0068] In the description of this invention, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated.

[0069] Figures 1 to 8 The structure of a miniaturized honeycomb paper machine according to one embodiment of the present invention is shown schematically.

[0070] refer to Figures 1 to 8 A miniaturized honeycomb paper machine includes a feed roller 1, an output roller 2, a support rod 3, and a pressure mechanism 4. Furthermore, the miniaturized honeycomb paper machine may also include a support frame 5, a base plate 6, a guide roller 7, a cutter module 8, a handle 9, a guide rail 10, an upper support rod 20, a front guide roller 30, a first guide plate 40, a second guide plate 50, a third guide plate 60, and a front housing 70.

[0071] refer to Figure 2 and Figure 3 There are two support frames 5, which can be arranged in parallel. The two support frames 5 can be used to support and install related components.

[0072] refer to Figure 2 and Figure 3The two ends of the paper feed roller 1 are respectively inserted and installed (e.g., through bearings) on two support frames 5, and the paper feed roller 1 can rotate on the two support frames 5. The two ends of the paper output roller 2 are respectively inserted and installed (e.g., through bearings) on two support frames 5, and the paper output roller 2 can rotate on the two support frames 5. There are two paper output rollers 2, and a pair of paper output rollers 2 are arranged vertically. The rotation directions of the pair of paper output rollers 2 are opposite. In this embodiment, the structure of the paper output roller 2 and the installation method of the pair of paper output rollers 2 are existing technologies and will not be described in detail, such as the vertically arranged roller shafts in the announcement number CN113184599B.

[0073] refer to Figure 2 and Figure 3 A motor (not shown) installed inside the support frame 5 drives the drive wheel 201 to rotate. The drive wheel 201 drives the first driven wheel 202 at one end of the upper paper output roller 2 to rotate via a belt. The first driven wheel 202 drives the upper paper output roller 2 to rotate. The upper paper output roller 2 can drive the lower paper output roller 2 to rotate in the opposite direction via meshing gears. The first driven wheel 202 at the other end of the upper paper output roller 2 drives the second driven wheel 101 at the end of the paper feed roller 1 to rotate via a belt. 01 drives the paper feed roller 1 to rotate. The rotation speed of the paper output roller 2 is greater than that of the paper feed roller 1. That is, there is a speed difference between the paper output roller 2 and the paper feed roller 1. In this way, the honeycomb paper consumable between the paper output roller 2 and the paper feed roller 1 will be subjected to a pulling force along the surface of the consumable and in the same direction as the consumable's movement. This allows the honeycomb paper between the paper output roller 2 and the paper feed roller 1 to unfold into a three-dimensional shape. The rotation speed of the paper feed roller 1 and the rotation speed of the paper output roller 2 can be adjusted and set by the model and size of the first driven wheel 202 and the second driven wheel 101.

[0074] refer to Figure 2 The support frame 5 has a receiving groove 51 formed on it. The receiving groove 51 is arranged longitudinally and slightly inclined. The top of the receiving groove 51 is open. The two ends of the bearing rod 3 can be respectively received in the two receiving grooves 51 on the two support frames 5. The bearing rod 3 is used to support the honeycomb paper roll. When the bearing rod 3 supports the honeycomb paper roll, the bottom of the honeycomb paper roll can press against the paper feeding roller 1. (Refer to...) Figure 2 , Figure 3 and Figure 6 The paper feed roller 1 is provided with multiple rings 11 arranged at equal intervals along the length of the paper feed roller 1. When the support rod 3 carries the honeycomb paper roll, the bottom of the honeycomb paper roll can press against the rings 11 on the paper feed roller 1. The paper feed roller 1 can increase the friction between the two by having multiple rings 11 close to the bottom of the honeycomb paper roll, and further prevent the honeycomb paper and the paper feed roller 1 from slipping when the honeycomb paper roll is unwound to a small diameter.

[0075] refer to Figure 2 and Figure 11The bottom support plate 6 is arc-shaped, and its two ends can be installed on two support frames 5 respectively. The bottom support plate 6 has multiple perforations 61 formed on it. The width of the perforations 61 is slightly larger than the width of the ring 11 on the paper feed roller 1. The interval between two adjacent perforations 61 is slightly smaller than the interval between two adjacent rings 11 on the paper output roller 1. The number of perforations 61 is the same as the number of rings 11 on the paper feed roller 1. The rings 11 on the paper feed roller 1 are inserted into the perforations 61 on the bottom support plate 6 from the bottom upward. The top of the rings 11 extends from the upper surface of the bottom support plate 6. The arc-shaped bottom support plate 6 can guide the unwinding of the honeycomb paper roll, reducing the risk of the honeycomb paper being stuck before entering the paper output roller 2. In addition, the bottom support plate 6 can collect paper scraps, catching some of the paper scraps generated by the stretching of the honeycomb paper roll during unwinding.

[0076] The pressure mechanism 4 can drive the support rod 3 to maintain a tendency to move towards the paper feed roller 1 so that the bottom of the honeycomb paper roll material carried on the support rod 3 is in close contact with the paper feed roller 1. In this embodiment, there are two pressure mechanisms 4. One pressure mechanism 4 is set on one support frame 5, and the other pressure mechanism 4 is set on another support frame 5. The two pressure mechanisms 4 can simultaneously apply pressure to both ends of the support rod 3 so that the honeycomb paper roll material carried on the support rod 3 is in close contact with the paper feed roller 1 in the width direction, ensuring stable unwinding of the honeycomb paper roll material. The two pressure mechanisms 4 have the same structure and are installed on the two support frames 5 in the same way. The structure of one press mechanism 4 on one support frame 5 will be described below. Specifically, refer to Figures 2 to 5 The pressure mechanism 4 includes a rotating pressure plate 41 and a first tensioning member 42. One end of the rotating pressure plate 41 is hinged to the support frame 5, and one end of the first tensioning member 42 is fixed to the support frame 5. The other end of the first tensioning member 42 is fixed to the rotating pressure plate 41 near the center. The other end of the rotating pressure plate 41 is used to press against the bearing rod 3. The first tensioning member 42 can drive the rotating pressure plate 41 to apply pressure to the bearing rod 3 so that the bottom of the honeycomb paper roll carried on the bearing rod 3 is pressed tightly against the ring 11 on the paper feed roller 1. When the rotating pressure plate 41 applies pressure to the bearing rod 3 (e.g. Figure 10 , Figure 12 , Figure 13As shown, the rotating pressure plate 41 can drive the support rod 3 to maintain a tendency to move towards the paper feed roller 1 so that the bottom of the honeycomb paper roll material carried on the support rod 3 is in close contact with the ring 11 on the paper feed roller 1. Since the rotating pressure plate 41 can rotate on the support frame 5, under the pulling force of the first tensioning member 42, the rotating pressure plate 41 can always press against the support rod 3, applying pressure to the support rod 3. During the unwinding process, as the unwinding radius decreases, the support rod 3 will move towards the paper feed roller 1 in the receiving groove 51 on the support frame 5. At the same time, under the pressure applied by the rotating pressure plate 41, the bottom of the honeycomb paper roll material carried on the support rod 3 is always in close contact with the ring 11 on the paper feed roller 1, ensuring stable paper feeding by the paper feed roller 1 and preventing slippage between the honeycomb paper and the paper feed roller 1 when the honeycomb paper roll material is unwound to a small diameter.

[0077] The structure will now be described using a press mechanism 4 mounted on a support frame 5. For details, please refer to [reference needed]. Figures 2 to 5 The pressure mechanism 4 also includes a limiting plate 43 and a second tensioning component 44. The limiting plate 43 is hinged to the support frame 5 near its center. One end of the second tensioning component 44 is fixed to the support frame 5, and the other end of the second tensioning component 44 is fixed to one end of the limiting plate 43. A groove 431 is formed on the other end of the limiting plate 43. An arc-shaped edge 432 is formed on the side of the limiting plate 43 near the receiving groove 51. A first pin 411 is installed on the side of the rotating pressure plate 41 near the support frame 5. When the rotating pressure plate 41 and the limiting plate 43 are in the initial state ( Figure 9 The state shown is the initial state. The first pin 411 on the rotating pressure plate 41 is engaged in the slot 431 on the limiting plate 43. Before feeding, that is, before the bearing rod 3 carrying the honeycomb paper roll is placed in the receiving slot 51 of the support frame 5, the rotating pressure plate 41 and the limiting plate 43 are in the initial state. Figure 9 As shown), at this time, the first pin 411 on the rotating pressure plate 41 is engaged in the slot 431 on the limiting plate 43, and the rotating pressure plate 41 and the limiting plate 43 are locked together, which facilitates feeding and placing the bearing rod 3 in the receiving groove 51 of the support frame 5; as the unwinding radius decreases, the bearing rod 3 moves towards the paper feed roller 1 in the receiving groove 51 on the support frame 5. When the bearing rod 3 in the receiving groove 51 presses against the arc-shaped edge 432 on the limiting plate 43 ( Figure 10 (As shown in the diagram), the bearing rod 3 drives the limiting plate 43 to swing so that the first pin 411 on the rotating pressure plate 41 disengages from the slot 431 on the limiting plate 43. At this time, the rotating pressure plate 41 presses against the bearing rod 3. Figure 10As shown, the support rod 3 carrying the honeycomb paper roll is placed in the receiving groove 51 on the support frame 5. Under the action of gravity, the support rod 3 will press against the arc-shaped edge 432 on the limiting plate 43, thereby driving the limiting plate 43 to swing on the support frame 5. At this time, the first pin 411 on the rotating pressure plate 41 will disengage from the slot 431 on the limiting plate 43, and the rotating pressure plate 41 and the limiting plate 43 will be unlocked. Under the pulling force of the first tensioning component 42, the rotating pressure plate 41 swings on the support frame 5, and the rotating pressure plate 41 always presses against the support rod 3. Figure 12 (As shown in the diagram), the rotating pressure plate 41 applies pressure to the bearing rod 3, ensuring that the bottom of the honeycomb paper roll carried on the bearing rod 3 is tightly pressed against the ring 11 on the paper feed roller 1, thus stabilizing the paper feeding by the paper feed roller 1; as the unwinding radius further decreases, when the rotating pressure plate 41 and the limiting plate 43 are in the finishing state, the arc-shaped edge 432 on the limiting plate 43 presses against the first pin 411 on the rotating pressure plate 41, and the rotating pressure plate 41 presses against the bearing rod 3 ( Figure 13 As shown in the diagram, when the rotating pressure plate 41 and the limiting plate 43 are in the finishing state, i.e., when the honeycomb paper roll is unwound to the small diameter, under the pulling force of the second tensioning member 44, the arc-shaped edge 432 on the limiting plate 43 presses against the first pin 411 on the rotating pressure plate 41. Under the pulling force of the first tensioning member 42, the rotating pressure plate 41 presses against the bearing rod 3. In this way, under the dual pressure of the limiting plate 43 and the rotating pressure plate 41, the bottom of the small diameter honeycomb paper roll is ensured to be tightly attached to the ring 11 on the paper feeding roller 1, preventing the paper feeding roller 1 from jumping and the honeycomb paper from slipping on the paper feeding roller 1.

[0078] refer to Figure 2 and Figure 3 A second pin 52 is installed on the support frame 5. The second pin 52 is located on the side of the rotating pressure plate 41. The second pin 52 is used to limit the swing range of the rotating pressure plate 41. During the swinging process, when the rotating pressure plate 41 abuts against the second pin 52, the first pin 411 on the rotating pressure plate 41 will not cross the end of the limiting plate 43 that is provided with the slot 431. Figure 2The top of the middle limiting plate 43 ensures that the first pin 411 will not disengage from the slot 431. When the honeycomb paper roll is unwound, the bearing rod 3 needs to be removed, and the rotating pressure plate 41 is lifted. The second pin 52 can limit the range of the lifting angle of the rotating pressure plate 41. When the rotating pressure plate 41 is lifted to abut against the second pin 52, the first pin 411 on the rotating pressure plate 41 is once again engaged in the slot 431 on the limiting plate 43, realizing the interlocking of the rotating pressure plate 41 and the limiting plate 43. The rotating pressure plate 41 and the limiting plate 43 return to their initial state. At this time, the bearing rod 3 can be removed from the support. The material is removed from the receiving groove 51 on the support frame 5 for easy unloading. The second pin 52 can prevent the rotating pressure plate 41 from swinging too much when it is lifted, causing the first pin 411 on the rotating pressure plate 41 to cross the end of the limiting plate 43 with the slot 431. This would prevent the rotating pressure plate 41 and the limiting plate 43 from returning to their initial state when loading the material next time. Under the pulling force of the second tensioning component 44, the limiting plate 43 will block the opening of the receiving groove 51 on the support frame 5, making it impossible to load the material, that is, the bearing rod 3 carrying the honeycomb paper roll material cannot be placed in the receiving groove 51 on the support frame 5.

[0079] In this embodiment, the design of the arc-shaped edge 432 on the limiting plate 43 ensures that when the support rod 3 is placed in the receiving groove 51 on the support frame 5, the limiting plate 43 will swing under the gravity of the support rod 3 and the honeycomb paper roll, thereby causing the first pin 411 on the rotating pressure plate 41 to disengage from the slot 431 on the limiting plate 43, thus unlocking the rotating pressure plate 41 and the limiting plate 43. Moreover, the arc-shaped edge 432 on the limiting plate 43 allows the support rod 3 to move smoothly and steadily in the receiving groove 51 on the support frame 5. The second pin 52 prevents the rotating pressure plate 41 from swinging too much when it is lifted, causing the first pin 411 on the rotating pressure plate 41 to cross the end of the limiting plate 43 with the slot 431. Therefore, the shape of the slot 431 and the arc edge 432 on the limiting plate 43, as well as the position of the second pin 52 and the first pin 411 on the rotating pressure plate 41, are particularly important. This determines whether the rotating pressure plate 41 and the limiting plate 43 can be kept in the designated position when the honeycomb paper is taken out after use, so as to facilitate the next feeding.

[0080] In this embodiment, both the first tensioning component 42 and the second tensioning component 44 are tension springs. During the unwinding process, the honeycomb paper roll on the support rod 3 is pressed against the bearing rod 3 by the rotating pressure plate 41 under the tension of the tension spring. The rotating pressure plate 41 applies pressure to the bearing rod 3, causing the bottom of the honeycomb paper roll on the bearing rod 3 to be tightly pressed against the ring 11 on the paper feed roller 1. During the unwinding process, under the tension of the tension spring, the arc-shaped edge 432 on the limiting plate 43 can be pressed tightly against the bearing rod 3 in the receiving groove 51, so that... The support rod 3 can move smoothly and steadily toward the paper feed roller 1 in the receiving groove 51 on the support frame 5. In addition, when the rotating pressure plate 41 and the limiting plate 43 are in the finishing state, that is, when the honeycomb paper roll is unwound to the small diameter, under the tension of the tension spring, the arc edge 432 on the limiting plate 43 can be firmly pressed against the first pin 411. Under the tension of the tension spring, the rotating pressure plate 41 presses against the support rod 3, ensuring that the bottom of the small diameter honeycomb paper roll is tightly attached to the ring 11 on the paper feed roller 1.

[0081] refer to Figure 2 and Figure 11 The guide roller 7 is located on the side of the bottom support plate 6. The two ends of the guide roller 7 are mounted on two support frames 5. The guide roller 7 can rotate on the support frame 5. The honeycomb paper roll material carried on the support rod 3 can pass around the guide roller 7 and enter between the two output rollers 2. The guide roller 7 can make the honeycomb paper roll material carried on the support rod 3 enter between the two output rollers 2 more smoothly and steadily.

[0082] refer to Figure 11 The first guide plate 40 and the second guide plate 50 are installed below the paper feeding roller 1. The ends of the first guide plate 40 and the second guide plate 50 are fixed on the support frame 5. The honeycomb paper roll material carried on the support rod 3 passes around the guide roller 7 and enters the space between the two paper output rollers 2 through the channel between the first guide plate 40 and the second guide plate 50, ensuring that the honeycomb paper roll material carried on the support rod 3 enters the space between the two paper output rollers 2 more smoothly and steadily.

[0083] refer to Figures 1 to 3 Each of the two support frames 5 has a bracket 501 mounted on its top. The top of each bracket 501 has an L-shaped slot 502 formed therein. The two ends of the upper support rod 20 are engaged in the L-shaped slots 502 on the two brackets 501. The upper support rod 20 can rotate on the bracket 501. The upper support rod 20 is used to support the tissue paper roll material (e.g., ...). Figures 10 to 12 As shown), a front housing 70 is installed between the two support frames 5, and the cutter module 8 is installed in the front housing 70. (See reference) Figure 2 and Figure 11A front guide roller 30 is installed on the top of the front housing 70, and a third guide plate 60 is installed below the bottom support plate 6. The end of the third guide plate 60 is fixed to the support frame 5. The tissue paper roll carried on the upper support rod 20 passes around the front guide roller 30 and enters the space between the two paper output rollers 2 together with the honeycomb paper through the channel between the bottom support plate 6 and the third guide plate 60. The three-dimensional honeycomb paper is packaged with tissue paper, and its core function is to provide complementary protection and improve the packaging effect. The honeycomb paper is responsible for "impact resistance", and the tissue paper is responsible for "detail protection". The combination of the two is a combination of "strong cushioning + fine protection", which can take into account both the practicality and aesthetics of the packaging. In other embodiments, depending on the packaging needs, the bracket 501 and the upper support rod 20 may not be installed, that is, tissue paper may not be used for packaging.

[0084] refer to Figure 2 and Figure 3 The cutter module 8 is installed in the front housing 70 and is located downstream of the paper output roller 2. The cutter module 8 is used to cut the three-dimensional honeycomb paper and tissue paper fed out by the paper output roller 2.

[0085] refer to Figure 2 , Figure 3 , Figure 7 and Figure 8The cutter module 8 includes a drive component 81, a timing belt 82, a cutter 83, a cutter holder 84, a fixed cutter 85, a slide 86, a first gear 87, a second gear 88, a connecting shaft 89, a rack 810, a tension spring 811, and a retaining spring 812. The drive component 81 is mounted on a support frame 5 and can be a motor. The drive component 81 drives the timing belt 82 via a pulley. A portion of the timing belt 82 spans between two support frames 5. The timing belt 82 located between the two support frames 5 is preferably arranged parallel to the paper output roller 2. The slide 86 is fixed to the timing belt 82. 2. When the drive unit 81 drives the synchronous belt 82 to convey and reverse, the synchronous belt 82 can drive the slide 86 to reciprocate downstream of the paper output roller 2 in a direction perpendicular to the paper output direction. The first gear 87 and the second gear 88 are both mounted on the slide 86 and can rotate on the slide 86. For example, the first gear 87 and the second gear 88 are both fixed to two bearings respectively by a shaft component. The bearings are mounted on the slide 86. The first gear 87 is located above the second gear 88. The first gear 87 meshes with the rack 810, and the second gear 88 meshes with the first gear 87. The rack 810 is arranged parallel to the paper output roller 2. The teeth on the rack 810 are located at the bottom of the rack 810 to mesh with the first gear 87. The second gear 88 is connected to the knife holder 84 through the connecting shaft 89. When the second gear 88 rotates, it can drive the knife holder 84 to rotate through the connecting shaft 89. The cutter 83 is mounted on the knife holder 84, and the knife holder 84 is mounted on the timing belt 82 through the slide 86. The fixed blade 85 is arranged parallel to the paper output roller 2 and is located downstream of the paper output roller 2. The cutter 83 is attached to the fixed blade 85. When the drive component 81 drives the timing belt... During transmission, the synchronous belt 82 drives the knife holder 84 to reciprocate along the rack 810 via the slide 86. The first gear 87 on the slide 86 rolls along the rack 810, driving the second gear 88 to rotate. The second gear 88 drives the knife holder 84 to rotate via the connecting shaft 89, which in turn drives the cutter 83 to rotate. The cutter 83 moves and rotates along the length of the rack 810. Since the cutter 83 is attached to the fixed blade 85, the rotating cutter 83, in cooperation with the fixed blade 85, cuts the three-dimensional honeycomb paper and tissue paper fed out by the paper output roller 2.

[0086] refer to Figure 1 When the motor, which is the driving component 81, rotates forward, the slide 86 moves from the left side to the right side along the rack 810. When the motor, which is the driving component 81, rotates in reverse, the slide 86 moves from the right side to the left side along the rack 810.

[0087] refer to Figure 8A conical boss 841 is formed on the left end of the cutter holder 84. In this embodiment, the cutter 83 is circular. The retaining spring 812 is sleeved on the cutter holder 84 and fixedly connected to it. The cutter 83 is sleeved on the cutter holder 84 and can move along the axial direction of the cutter holder 84 (the diameter of the mounting hole on the cutter 83 can be slightly larger than the outer diameter of the cutter holder 84). The cutter 83 is located between the retaining spring 812 and the conical boss 841. The tension spring 811 is placed around the conical surface 8411 of the conical boss 841. The tension spring 811 can drive the cutter 83 to move towards the retaining spring 812 so that the cutter 83 fits against the fixed blade 85. Under the restoring force of the tension spring 811, the cutter 83 maintains a tendency to move towards the retaining spring 812, so that the cutter 83 can remain in contact with the fixed blade 85 during the cutting of the honeycomb paper. At the same time, the cutter 83 has a certain floating space along the axial direction of the blade holder 84, thereby ensuring that the cutter 83 and the fixed blade 85 do not produce abnormal noise while cutting the honeycomb paper.

[0088] refer to Figure 3 and Figure 7 The handle 9 is inserted and fixed on a connecting frame 861 on the top of the slide 86. The slide 86 is fixed on the timing belt 82 through the connecting frame 861. When the handle 9 is turned, the handle 9 can drive the slide 86 to move back and forth along the rack 810. When it is necessary to cut the three-dimensional honeycomb paper sent by the paper output roller 2, electric cutting can also be performed without the use of the drive component 81. The handle 9 can be turned along the length direction of the rack 810. The handle 9 drives the slide 86 to move along the length direction of the rack 810. The first gear 87 on the slide 86 rolls along the rack 810. The first gear 810 drives the second gear 88 to rotate. The second gear 88 drives the knife holder 84 to rotate through the connecting shaft 89. The knife holder 84 drives the cutter 83 to rotate. The cutter 83 moves along the length direction of the rack 810 while rotating. The rotating cutter 83, in cooperation with the fixed knife 85, cuts the three-dimensional honeycomb paper sent by the paper output roller 2, realizing manual cutting. The miniaturized honeycomb paper machine of the present invention can be compatible with manual / electric cutting of honeycomb paper.

[0089] refer to Figure 3 and Figure 7 The guide rail 10 is arranged parallel to the paper output roller 2. The end of the guide rail 10 can be mounted on the support frame 5. The slide block 86 is slidably mounted on the guide rail 10 through the slider 862. The slide block 86 can move smoothly along the guide rail 10 to ensure that the cutter 83 can smoothly cut the three-dimensional honeycomb paper sent out by the paper output roller 2.

[0090] The miniaturized honeycomb paper machine of this invention can use honeycomb paper rolls with a full roll diameter of 220mm and a width of 500mm, and can also use tissue paper rolls with a full roll diameter of 200mm and a width of 300mm. The overall machine dimensions are as follows. Figure 1 As shown, the machine length L = 680mm, as Figure 9 As shown, the width W=260mm, the bare machine height H=260mm, and the height after adding the tissue paper roll is 555mm.

[0091] refer to Figures 1 to 13 The miniaturized honeycomb paper machine of the present invention, when producing honeycomb paper for packaging items, places the honeycomb paper roll 80 on the support rod 3 and the tissue paper roll 90 on the upper support rod 20. Before feeding, the rotating pressure plate 41 and the limiting plate 43 are in position. Figure 9 In the initial state shown, the rotating pressure plate 41 and the limiting plate 43 are locked together, and the bearing rod 3 is placed in the receiving groove 51 of the support frame 5. The honeycomb paper roll 80 carried on the bearing rod 3 passes around the guide roller 7 and enters between the two paper output rollers 2 through the channel between the first guide plate 40 and the second guide plate 50. The tissue paper roll 90 carried on the upper bearing rod 20 passes around the front guide roller 30 and enters between the bottom support plate 6 and the third guide plate 60. The honeycomb paper enters between the two output rollers 2. Under the action of gravity, the support rod 3 presses against the arc-shaped edge 432 on the limiting plate 43. When the support rod 3 presses against the arc-shaped edge 432 on the limiting plate 43, the support rod 3 drives the limiting plate 43 to swing on the support frame 5. At this time, the first pin 411 on the rotating pressure plate 41 disengages from the slot 431 on the limiting plate 43, and the rotating pressure plate 41 and the limiting plate 43 are unlocked. The rotating pressure plate 41 presses against the support rod 3. Figure 10 As shown), under the tension of the first tensioning member 42, the rotating pressure plate 41 swings on the support frame 5, and the rotating pressure plate 41 always presses against the bearing rod 3. Figure 12 (As shown in the diagram), the rotating pressure plate 41 applies pressure to the support rod 3, ensuring that the bottom of the honeycomb paper roll supported on the support rod 3 is pressed tightly against the ring 11 on the paper feed roller 1, thus stabilizing the paper feeding of the paper feed roller 1. As the unwinding radius decreases, the support rod 3 moves towards the paper feed roller 1 in the receiving groove 51 on the support frame 5. As the unwinding radius further decreases, when the rotating pressure plate 41 and the limiting plate 43 are in the finishing state, the arc-shaped edge 432 on the limiting plate 43 presses against the first pin 411 on the rotating pressure plate 41, and the rotating pressure plate 41 presses against the support rod 3. Figure 13As shown in the diagram, when the rotating pressure plate 41 and the limiting plate 43 are in the finishing state, i.e., when the honeycomb paper roll 80 is unwound to the small diameter, under the tension of the second tensioning member 44, the arc-shaped edge 432 on the limiting plate 43 presses against the first pin 411 on the rotating pressure plate 41. Under the tension of the first tensioning member 42, the rotating pressure plate 41 presses against the bearing rod 3. Thus, under the dual pressure of the limiting plate 43 and the rotating pressure plate 41, the bottom of the small diameter honeycomb paper roll 80 is ensured to be tightly attached to the paper feed roller 1. On the ring 11, to prevent the paper feeding roller 1 from jumping and the honeycomb paper from slipping on the paper feeding roller 1; the miniaturized honeycomb paper machine of the present invention, when the motor drives the paper feeding roller 1 and the paper output roller 2 to rotate, can use the speed difference between the paper output roller 2 and the paper feeding roller 1 to unfold the honeycomb paper fed from the honeycomb paper roll 80 into a three-dimensional shape. The three-dimensional honeycomb paper can be used to pack items. The cutter 83 in the cutter module 8 can cut the three-dimensional honeycomb paper and tissue paper fed from the paper output roller 2. During the unwinding process, the pressure mechanism 4 can The pressure is applied to the support rod 3 to keep it moving towards the paper feed roller 1. This ensures that the bottom of the honeycomb paper roll 80 carried on the support rod 3 is in close contact with the paper feed roller 1. The pressure mechanism 4 ensures stable paper feeding by the paper feed roller 1 after applying pressure to the support rod 3, preventing jumping during the paper feeding process, especially when the honeycomb paper roll 80 is unwound to a small diameter. The miniaturized honeycomb paper machine of the present invention no longer requires two pairs of rubber rollers when the honeycomb paper is stretched and unfolded. The paper feed roller 1 is a single roller, which simplifies the structure, reduces costs, and reduces size and weight. In addition, during the unwinding process of the honeycomb paper roll, the support rod 3 moves towards the paper feed roller 1 in the receiving groove 51 on the support frame 5, and the bottom of the honeycomb paper roll is always pressed against the paper feed roller 1. The honeycomb paper roll and the single-roll paper feed roller 1 are in a close fit state, and no gap is required. Thus, the device of the present invention can be compatible with honeycomb paper consumables with larger roll diameters while maintaining a size similar to that of honeycomb paper machines on the market. It can also be compatible with manual / electric cutting of honeycomb paper.

[0092] The above descriptions are merely some embodiments of the present invention.
