Description

Technical Field

[0001] This invention relates to a cushioning paper pad machine. Background Technology

[0002] Existing cushioning pad production equipment, i.e., cushioning pad machines, typically rely on gear meshing and pressing, along with puncture wheel puncture and shaping, to convey, deform, and shape kraft paper consumables (i.e., padding materials). However, due to the physical deformation requirements of the kraft paper consumables as they transform from a planar to a three-dimensional structure, the forming channel of the cushioning pad machine needs to provide a relatively long wrap angle distance to ensure sufficient folding and shrinkage of the kraft paper consumables. This results in a lengthy forming channel, leading to an excessively long longitudinal dimension (in the kraft paper consumable conveying direction) of the equipment. Existing cushioning pad machines suffer from the following drawbacks: 1. Due to their long forming flow channels and loose component layout, cushioning paper pad machines generally suffer from problems such as large overall size, loose overall structure, low spatial integration, and heavy weight. This low integration design limits the flexibility of equipment deployment in confined spaces.

[0003] 2. The complex mechanical structure results in a compact and concealed layout of the internal transmission chain and electrical components, making them difficult to access during maintenance and repair. In the event of a paper jam, operators must remove multiple layers of the outer shell and internal components to clean the paper, making the maintenance process cumbersome and the downtime long.

[0004] 3. The lack of effective vibration and noise reduction between the power components and the frame results in significant mechanical vibration and noise during high-speed operation of the equipment. Existing buffer paper pad machines lack effective vibration and noise reduction design between the drive system and the frame, resulting in significant mechanical vibration and aerodynamic noise from the high-speed gear meshing, pressing, and puncturing actions.

[0005] 4. Due to the lack of a built-in debris collection and cleaning mechanism, paper scraps and dust generated during the production process are very easy to accumulate inside the shell, and the operation of disassembling the external protective cover and shell is cumbersome, time-consuming and laborious for operators.

[0006] 5. In terms of safety protection, the hand protection design has obvious defects and the protection is not thorough. The existing paper cushioning machines mostly use passive isolation methods such as extended discharge ports or curved guards at the paper outlet. However, when paper blockage occurs, operators may still manually reach into the paper outlet to clean the paper, resulting in cuts and scratches to their hands.

[0007] 6. In order to reduce noise while ensuring the forming quality of the cushioning paper pads, the existing cushioning paper pad machines are set at a relatively slow speed, resulting in low production efficiency of cushioning paper pads.

[0008] 7. Due to the large power consumption of the entire machine, the existing cushioning paper pad machine cannot be adapted to battery power to achieve mobile operation. It can only rely on wired power to operate, and the update and upgrade of the control program also requires opening the shell for operation. It lacks a convenient external interaction interface and cannot meet the needs of humanized production.

[0009] 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

[0010] The purpose of this invention is to provide a cushioning paper pad machine to solve at least one of the above-mentioned technical problems.

[0011] According to one aspect of the present invention, a cushioning paper pad machine is provided, comprising: The paper pad machine body has a paper inlet that gradually narrows in cross-sectional area. Guide components that guide the downward-bending and inward-folding sides of the padding material are located in the paper inlet of the paper padding machine body. The guiding component includes a guide and a support. The guide is located on top of the support, and the bottom of the support is located on the inner bottom of the paper inlet. The width of the guide gradually decreases from the paper inlet to the paper outlet of the paper press body. The guide roller has tapered ends and is located upstream of the paper inlet of the paper pad machine body. The padding material passes over the guide roller from the top and enters the paper feed inlet of the paper pad machine body.

[0012] In this invention, the cushioning paper pad machine first guides the padding material (i.e., raw material consumable) into the paper inlet of the machine body via guide rollers. After shrinking and forming at the paper inlet, it is then pressed and shaped into a cushioning paper pad by the paper pad forming mechanism inside the machine body and sent out to the paper outlet of the machine body. The cutting mechanism inside the machine body cuts the delivered cushioning paper pad to a set length, thus producing the cushioning paper pad. Since both ends of the guide rollers are conical, when the padding material passes over the top of the guide rollers, the two ends of the guide rollers will pre-deform the sides of the padding material downwards. This differs from the deformation method of the traditional cushioning paper pad machine where the padding material folds upwards during feeding. In this invention, the padding material entering the paper inlet of the machine body naturally bends and folds inwards on both sides under the deformation guidance of the guide component. With only a short-distance guidance between the guide rollers and the guide component in the paper inlet, the padding material can shrink into the basic shape of the paper pad within the forming channel inside the machine body, and then... After the paper pad forming mechanism (meshing gears) inside the paper pad machine body presses and shapes the paper pad, it produces a cushioning paper pad. Traditional cushioning paper pad machines have a relatively long forming flow channel and a relatively gentle deformation guidance. In the cushioning paper pad machine of this invention, the guide roller and the T-shaped guide component in the paper inlet can quickly and violently deform and shrink the pad material. After passing through the paper inlet, the pad material can shrink from a width of 380mm to between 90mm and 100mm. This allows the pad material to immediately reach the paper pad forming mechanism (meshing gears) inside the paper pad machine body after passing through the paper inlet, thereby effectively shortening the length of the forming flow channel inside the paper pad machine body. It changes the traditional upward folding method of the pad material and adopts a feeding path in which the pad material naturally bends and folds inward. The pre-shrinking of the pad material can be completed with short-distance guidance, which can significantly shorten the length of the forming flow channel and realize the miniaturization of the whole machine. For example, the length from the paper inlet to the paper outlet of the paper pad machine body can be reduced from about 840mm to about 380mm.

[0013] In some embodiments, both sides of the guide can be arc-shaped, the middle part of the bottom of the guide can be concave, and the middle position of the inner bottom of the paper inlet can be provided with a protrusion extending from the paper inlet of the paper pad machine body to the paper outlet, and the bottom of the support is provided on the protrusion.

[0014] Therefore, the arc-shaped guides on both sides can guide the sides of the pad material to bend downwards smoothly and easily, and can also pull the pad material more smoothly and with low resistance. The middle part of the bottom of the concave guides can provide space for the inward fold after the sides of the pad material bend downwards, and the two sides of the protrusions can guide the edges of the sides of the pad material to curl upwards and deform.

[0015] In some embodiments, a tail frame may also be included, with one end of the tail frame disposed on the paper pad machine body and a guide roller disposed on the other end of the tail frame, and the tail frame and the paper pad machine body being detachably connected.

[0016] Therefore, the guide roller is mounted on the paper pad machine body via the tailstock, and is easy to install and remove.

[0017] In some embodiments, the device may further include a tilting plate and a support shaft. One side of the tilting plate is hinged to the inner wall of the paper pad machine body. The tilting plate has a through hole. The paper pad machine body includes an upper gear and a lower gear for conveying and pressing / piercing the padding material. The upper gear and the lower gear are meshing. The upper gear is sleeved on the support shaft and rotatably connected to the support shaft. The upper gear is housed in the through hole. Both ends of the support shaft are respectively located on the tilting plate. When the flip plate flips, the upper and lower gears can mesh or disengage.

[0018] Thus, the upper gear and the lower gear constitute the paper pad forming mechanism of the paper pad machine body. The meshing upper gear and the lower gear can convey, press, puncture and shape the pad material, and send it out to the paper outlet. When it is necessary to clean the pad material that is blocked or stuck in the forming channel of the paper pad machine body, the flip plate can be flipped open. The flip plate drives the upper gear and the lower gear to separate through the support shaft. At this time, the pad material and debris that are blocked or stuck in the forming channel can be removed very easily, realizing quick cleaning of the pad material.

[0019] In some embodiments, a preload bolt and a preload spring may also be included. The end of the preload bolt passes through the support shaft and is screwed into the flip plate. The preload spring is sleeved on the preload bolt. One end of the preload spring abuts against the nut of the preload bolt, and the other end of the preload spring abuts against the support shaft.

[0020] Thus, the axial elastic preload provided by the preload spring enables a non-rigid floating meshing connection between the upper and lower gears. At the same time, the elastic compensation effect of the preload spring ensures that the tooth surfaces of the upper and lower gears remain in close contact during high-speed operation.

[0021] In some embodiments, a first damping pad and a second damping block may also be included. The first damping pad is sleeved on the pre-tightening bolt and located between the support shaft and the flipping plate, and the second damping block is located at the bottom of the paper pad machine body.

[0022] Therefore, the first shock-absorbing pad can effectively reduce the vibration and noise of the gear set (upper gear and lower gear) during operation. The second shock-absorbing block at the bottom of the paper pad machine body and the first shock-absorbing pad form the whole machine's shock absorption system, which can effectively reduce the internal vibration and noise of the machine and block the vibration transmission between the paper pad machine body and the external mounting bracket.

[0023] In some embodiments, a cover may also be included, which is disposed on the flip plate and covers the upper gear.

[0024] Therefore, the cover over the upper gear can provide safety protection, preventing hands or tools from directly contacting the upper gear and causing safety risks when the housing of the paper pad machine is opened.

[0025] In some implementations, the top of the paper pad machine body may be provided with a flip-up cover. Once the top cover is flipped open, the electrical components inside the paper pad machine can be inspected and maintained.

[0026] Therefore, by simply flipping open the top cover, the electrical components inside the paper pad machine can be inspected and maintained. In addition, when paper blockage occurs inside the paper pad machine, the top cover can also be flipped open to clean up the paper debris.

[0027] In some implementations, the bottom of the paper pad machine body may be equipped with a flip-open dust removal cover. When the dust removal cover is flipped open, it can clean the paper scraps generated during the operation of the cutting mechanism and the paper feeding inside the paper pad machine body.

[0028] Therefore, the dust removal cover can be installed below the cutting mechanism inside the paper pad machine body. After flipping the dust removal cover open, the debris generated by the cutting mechanism cutting the pad material can be cleaned directly.

[0029] In some embodiments, a capacitance detection module and an alarm may also be included. The inner wall or outer periphery of the paper outlet of the paper pad machine body is provided with an electrode plate or at least a ring of electrode foil. The capacitance detection module can detect the capacitance value at the paper outlet. The controller of the paper pad machine body is electrically connected to the capacitance detection module and the alarm.

[0030] Therefore, when a hand or other non-insulating object enters the paper outlet, an electric field is generated between the hand or other non-insulating object and the electrode plate or electrode foil, resulting in capacitance. When only the buffer paper pad passes through the paper outlet of the paper pad machine body, the capacitance value at the paper outlet does not change significantly. However, when a hand or other non-insulating object enters the paper outlet, the capacitance value at the paper outlet changes significantly. By detecting the change in capacitance value at the paper outlet through the capacitance detection module, it can be determined whether a human body or other non-insulating object has entered the paper outlet of the paper pad machine body. When the operator... If an employee accidentally inserts their hand or other non-insulated object into the paper output slot, the machine will immediately stop operating and the alarm will sound. Capacitance change detection can be achieved by installing an electrode plate or wrapping at least one turn of electrode foil (such as copper foil, tin foil, aluminum foil, etc., which can be used as electrode materials) on the inner wall or outer perimeter of the paper output slot. This simplifies the structural design of the paper pad machine body and enables the detection of human body parts and other non-insulated objects in a compact structural space. Moreover, when the electrode foil is wrapped in multiple turns, the surface area of ​​the electrode can be increased, thereby improving the sensitivity of capacitance change detection.

[0031] In some embodiments, the tailstock may include a left tailstock and a right tailstock. The end face of the paper feed port of the paper pad machine body is provided with two slots. One end of the guide roller is located on one end of the left tailstock, and the other end of the left tailstock is inserted into one slot. The other end of the guide roller is located on one end of the right tailstock, and the other end of the right tailstock is inserted into another slot.

[0032] Therefore, the left and right tailstocks of the tailstock can be inserted into the two slots on the end face where the paper feed port is located, and can be tightened with screws. The quick-assembly and disassembly of the tailstock using the slot-type installation simplifies the tailstock installation process and improves the ease of operation.

[0033] In some implementations, the paper pad machine body may be equipped with a power socket and a USB port for connecting to an external power source.

[0034] Therefore, the paper pad machine can be powered by an external battery (such as a power bank) connected to a power socket, making it convenient for mobile operation. The program can be updated without disassembling the machine via a USB port, making machine maintenance convenient. Attached Figure Description

[0038] Figures 1 to 14 The structure of a cushioning paper pad machine according to one embodiment of the present invention is shown schematically.

[0039] refer to Figures 1 to 14A cushioning paper pad machine includes a paper pad machine body 1, a guide component 2, and a guide roller 3. Additionally, the cushioning paper pad machine may also include a tail frame 4, a tilting plate 5, a support shaft 6, a pre-tightening bolt 7, a pre-tightening spring 8, a first shock-absorbing pad 9, a second shock-absorbing block 10, a cover 11, a capacitance detection module, and an alarm.

[0040] refer to Figure 1 The paper pad machine body 1 can realize the conveying, deformation and shaping of pad material (i.e. raw material consumable).

[0041] refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 The paper inlet 101 of the paper pad machine body 1 is tapered with a gradually decreasing longitudinal cross-sectional area, and the paper inlet 101 is approximately trumpet-shaped.

[0042] refer to Figure 1 , Figure 10 and Figure 12 The paper inlet 101 of the paper pad machine body 1 is connected to the paper outlet 102 of the paper pad machine body 1 through the forming flow channel 113.

[0043] refer to Figures 1 to 3 The guide component 2 is installed in the paper inlet 101 of the paper pad machine body 1. The guide component 2 is used to guide the two sides of the pad material to bend downward and fold inward. Specifically, the guide component 2 includes a guide 21 and a support 22. The guide 21 is fixed to the top of the support 22. The guide 21 and the support 22 can be fixed by screws or integrally formed. The bottom of the support 22 is fixed (e.g. by screws) to the inner bottom of the paper inlet 101. The width of the guide 21 gradually decreases from the paper inlet 101 to the paper outlet 102 of the paper pad machine body 1. Under the deformation guidance of the guide 21 of the guide component 2, the two sides of the pad material entering the paper inlet 101 of the paper pad machine body 1 will naturally bend downward and fold inward.

[0044] refer to Figure 2 and Figure 3 Both sides of the guide 21 are arc-shaped, and the middle part of the bottom of the guide 21 is concave. The top of the support 22 is located at the center line of the concave cavity at the bottom of the guide 21. The two sides of the guide 21 are supported by the support 22 so that the two sides of the pad material can be bent downward and folded inward synchronously and symmetrically. The arc-shaped guide 21 can guide the two sides of the pad material to bend downward smoothly and smoothly, and can also pull the pad material more smoothly and with low resistance. The middle part of the bottom of the concave guide 21 can provide space for the inward fold after the two sides of the pad material bend downward.

[0045] refer to Figure 2 and Figure 3A protrusion 1011 is formed at the middle position of the inner bottom of the paper inlet 101 of the paper pad machine body 1. The protrusion 1011 extends from the paper inlet 101 to the paper outlet 102 of the paper pad machine body 1. The bottom of the support member 22 is fixed (e.g., by screws) on the protrusion 1011. Both sides of the protrusion 1011 are arc-shaped. The two sides of the protrusion 1011 can guide the edges of the pad material to curl upward and deform.

[0046] refer to Figures 1 to 4 The guide roller 3 is located upstream of the paper inlet 101 of the paper pad machine body 1. The padding material passes over the guide roller 3 from the top and enters the paper inlet 101 of the paper pad machine body 1. Both ends of the guide roller 3 are conical, that is, both ends of the guide roller 3 are formed with conical surfaces 31. Because both ends of the guide roller 3 are conical, when the padding material passes over the top of the guide roller 3, the conical surfaces 31 at both ends of the guide roller 3 will pre-deform the sides of the padding material downward, so that the sides of the padding material entering the paper inlet 101 of the paper pad machine body 1 will bend downward more naturally and easily. Because both ends of the guide roller 3 are conical, when the padding material passes over the top of the guide roller 3, the conical surfaces 31 at both ends of the guide roller 3 will pre-deform the sides of the padding material downward, thus making the sides of the padding material entering the paper inlet 101 of the paper pad machine body 1 bend downward more naturally and easily. The end will pre-deform the pad material by bending it downwards on both sides. Unlike the deformation method of the pad material folding upwards when feeding the traditional cushioning paper pad machine, the pad material entering the paper inlet 101 of the paper pad machine body 1 will be naturally bent inwards on both sides under the deformation guidance of the guide 21 of the guide component 2. With only the short-distance guidance between the guide roller 3 and the guide component 2 in the paper inlet 101, the pad material can shrink into the basic shape of the paper pad in the forming flow channel 113 inside the paper pad machine body 1. The guide roller 3 and the T-shaped guide component 2 can quickly and violently deform and shrink the pad material, thereby effectively shortening the length of the forming flow channel 113 inside the paper pad machine body 1 and realizing the miniaturization of the whole machine.

[0047] refer to Figures 1 to 4One end of the tailstock 4 is mounted on the paper pad machine body 1, and the guide roller 3 is mounted on the other end of the tailstock 4. The tailstock 4 is detachably connected to the paper pad machine body 1. The guide roller 3 is mounted on the paper pad machine body 1 through the tailstock 4, which facilitates assembly and disassembly. Specifically, the tailstock 4 includes a left tailstock 41 and a right tailstock 42, which are symmetrically arranged. The paper inlet 101 of the paper pad machine body 1 has two L-shaped slots 107 on its end face. One end of the guide roller 3 is fixed to one end of the left tailstock 41, and the other end of the left tailstock 41 is fixed to the other end of the guide roller 3. The guide roller 3 is inserted into a slot 107, and the other end of the guide roller 3 is fixed to one end of the right tailstock 42. The other end of the right tailstock 42 is inserted into another slot 107. The guide roller 3 can rotate between the left tailstock 41 and the right tailstock 42, or it can remain stationary. The left tailstock 41 and the right tailstock 42 of the tailstock 4 can be inserted into the two slots 107 on the end face where the paper feed port 101 is located, and can be tightened with screws. The quick-release tailstock with slot installation simplifies the disassembly and assembly process of the tailstock 4 and improves the ease of operation.

[0048] refer to Figures 5 to 7 , Figure 10 , Figure 12One side of the flip plate 5 is hinged to a frame mounted on the inner wall of the paper pad machine body 1 via a flip hinge 54. The other side of the flip plate 5 is fixed to the frame inside the paper pad machine body 1 via a captive screw. The flip plate 5 is easy to open by simply loosening the captive screw. The frame mounted on the inner wall of the paper pad machine body 1 is used to install and support related components inside the paper pad machine body 1 and is not protected by this invention. An upper gear 103 and a lower gear 104 are installed inside the paper pad machine body 1. The upper gear 103 and the lower gear 104 can mesh together. The meshing part of the upper gear 103 and the lower gear 104 is located in the forming flow channel 113. The upper gear 103 and the lower gear 104 are used to convey and press and puncture the pad material. A perforation 51 is formed on the flip plate 5. The upper gear 103 is sleeved on the support shaft 6 and rotatably connected to the support shaft 6. The upper gear 103 can be mounted on the support shaft 6 via a bearing. The upper gear 103 accommodates... In the perforation 51, both ends of the support shaft 6 are respectively mounted on the flip plate 5. To prevent the support shaft 6 from rotating on the flip plate 5, two opposing flat portions can be formed on the circumference of the support shaft 6. One flat portion of the support shaft 6 abuts against the flip plate 5, and both ends of the support shaft 6 can abut against the flip plate 5 through a pad 53. The pad 53 is fixed to the flip plate 5, which increases the tightening amount at the end of the pre-tightening bolt 7. Even if the thickness of the flip plate 5 is relatively thin, the flip plate 5 and the pad 53... The combined thickness is used to tighten the end of the pre-tightening bolt 7. When the flip plate 5 flips, the upper gear 103 and the lower gear 104 can mesh or disengage. The upper gear 103 and the lower gear 104 constitute the paper pad forming mechanism of the paper pad machine body 1. The meshing upper gear 103 and lower gear 104 can convey, press, puncture and shape the pad material, and send it to the paper outlet 102. When it is necessary to clean the pad material blocked or jammed in the forming flow channel 113 of the paper pad machine body 1, the flip plate 5 can be flipped open. Figure 12 (As shown in the diagram), the flip plate 5 drives the upper gear 103 and the lower gear 104 to separate via the support shaft 6. At this time, the pad material and debris that are blocked or stuck in the molding channel 113 can be removed very easily, and the pad material can be cleaned quickly.

[0049] refer to Figure 5 and Figure 6In this embodiment, the support shaft 6 and the flip plate 5 are installed as follows: the end of a pre-tightening bolt 7 passes through the support shaft 6 located on one side of the through hole 51 and is then screwed into the pad 53 and the flip plate 5. The inner diameter of the through hole on the support shaft 6 through which the pre-tightening bolt 7 passes is slightly larger than the outer diameter of the pre-tightening bolt 7. The pre-tightening bolt 7 can move up and down in the through hole on the support shaft 6. A pre-tightening spring 8 is fitted on the pre-tightening bolt 7, with one end abutting against the nut of the pre-tightening bolt 7 and the other end abutting against the support shaft 6. The end of another pre-tightening bolt 7 passes through the support shaft 6 located on the other side of the through hole 51 and is then screwed into the pad 53 and the flip plate 5. The inner diameter of the through hole on the support shaft 6 through which the pre-tightening bolt 7 passes is slightly larger than the outer diameter of the pre-tightening bolt 7. Another pre-tightening spring 8 is fitted on the pre-tightening bolt 7, with one end abutting against the nut of the pre-tightening bolt 7 and the other end abutting against the support shaft 6. Figure 6 A shim can be installed between the bottom end of the preload spring 8 and the support shaft 6. The axial elastic preload provided by the preload spring 8 enables the upper gear 103 and the lower gear 104 to form a non-rigid floating meshing connection. At the same time, the elastic compensation effect of the preload spring 8 ensures that the tooth surfaces of the upper gear 103 and the lower gear 104 are continuously and tightly engaged during high-speed operation.

[0050] refer to Figure 6 Two guide posts 52 are installed on the flip plate 5. The bottom of one guide post 52 passes through the support shaft 6 located on one side of the through hole 51 and is fixed to the flip plate 5. The bottom of the other guide post 52 passes through the support shaft 6 located on the other side of the through hole 51 and is fixed to the flip plate 5. A bushing can be installed between the guide post 52 and the support shaft 6. The support shaft 6 can float up and down along the guide post 52. The two guide posts 52 can ensure that the support shaft 6 and the upper gear 103 installed on the support shaft 6 float up and down smoothly.

[0051] refer to Figure 5 and Figure 6 There are two first damping pads 9. One first damping pad 9 is fitted on a pre-tightening bolt 7 and is located between the support shaft 6 and the pad 53 on the flip plate 5. The other first damping pad 9 is fitted on another pre-tightening bolt 7 and is located between the support shaft 6 and the pad 53 on the flip plate 5. The two first damping pads 9 can effectively reduce the vibration and noise of the gear set (upper gear 103 and lower gear 104) during operation.

[0052] refer to Figure 7 and Figure 10The second shock absorber 10 is installed at the bottom of the frame inside the paper pad machine body 1. The second shock absorber 10 at the bottom of the paper pad machine body 1 and the first shock absorber 9 form the shock absorption system of the whole machine. Through the synergistic effect of the second shock absorber 10 and the first shock absorber 9, the internal vibration and noise of the machine can be effectively reduced, and the vibration transmission between the paper pad machine body 1 and the external mounting bracket can be blocked.

[0053] refer to Figures 5 to 7 The cover 11 covers the upper gear 103. The edge of the opening of the cover 11 can be fixed to the periphery of the perforation 51 on the flip plate 5 by screws. The cover 11 covering the upper gear 103 can provide safety protection and prevent hands or tools from directly contacting the upper gear 103 when the shell of the paper pad machine body 1 is opened, thus preventing safety risks.

[0054] refer to Figure 10 The paper pad machine body 1 is equipped with a motor 114. A drive gear 110 is mounted on the shaft of the motor 114. A rotating shaft 112 is also mounted inside the paper pad machine body 1. A lower gear 104 is mounted on the rotating shaft 112 and rotates synchronously with the rotating shaft 112. A driven gear 111 is mounted at the end of the rotating shaft 112. The drive gear 110 and the driven gear 111 are connected by a synchronous chain. In this way, when the motor 114 is working, the drive gear 110 rotates, and the drive gear 110 drives the driven gear 111 to rotate through the synchronous chain. The driven gear 111 drives the rotating shaft 112 to rotate, and the rotating shaft 112 drives the lower gear 104 to rotate. The upper gear 103, which meshes with the lower gear 104, rotates in the opposite direction to the lower gear 104, thereby realizing the conveying and pressing / puncturing of the pad material in the forming flow channel 113.

[0055] refer to Figure 1 , Figure 4 and Figure 13 The top of the paper pad machine body 1 is equipped with a flip-up cover 105. The touch screen 115 of the paper pad machine body 1 is mounted on the flip-up cover 105. The flip-up cover 105 is mounted on the frame inside the paper pad machine body 1 via a hinge structure. When the flip-up cover 105 is flipped open... Figure 13 (As shown in the diagram), the electrical components inside the paper pad machine body 1 can be inspected and maintained. In addition, after flipping the flip plate 5 open, the pad material and debris that are blocked or stuck in the forming flow channel 113 can be removed very easily.

[0056] refer to Figure 8 and Figure 14The bottom of the paper pad machine body 1 is equipped with a flip-open dust removal cover 106. One side of the dust removal cover 106 can be installed on the bottom of the paper pad machine body 1 via a hinge structure, and the other side of the dust removal cover 106 can be fixed to the bottom of the paper pad machine body 1 via a captive screw. When the dust removal cover 106 is flipped open, it can clean the paper scraps generated during the operation of the cutting mechanism and the paper feeding inside the paper pad machine body 1. The dust removal cover 106 can be installed below the cutting mechanism inside the paper pad machine body 1. After flipping the dust removal cover 106 open, the debris generated by the cutting mechanism cutting the pad material can be cleaned directly.

[0057] refer to Figure 8 , Figure 9 and Figure 11 An electrode plate (not shown) or at least one ring of electrode foil (not shown) is installed on the inner wall or outer periphery of the paper outlet 102 of the paper pad machine body 1. The capacitance detection module is connected to the controller of the paper pad machine body 1, and the controller of the paper pad machine body 1 is connected to an alarm (not shown). The controller of the paper pad machine body 1 can control the motor 114 and the cutting mechanism of the paper pad machine body 1 to start or stop working. The capacitance detection module (not shown) can detect the capacitance value at the paper outlet 102 of the paper pad machine body 1 and send it to the controller of the paper pad machine body for processing. The capacitance detection module can adopt an LCR digital bridge, a resonant measurement module (LC resonant circuit), or an integrated capacitance detection chip. The detection chip of the capacitance detection module, the alarm, and the controller of the paper pad machine body 1 are all integrated on the circuit board inside the paper pad machine body 1. When a human hand or other non-insulating object enters the paper outlet 102, an electric field can be generated between the human hand or other non-insulating object and the electrode plate or electrode foil, thereby generating capacitance. When only the buffer paper pad passes through... When a human hand or other non-insulating object enters the paper outlet 102 of the paper pad machine body 1, the capacitance value at the paper outlet 102 does not change significantly. However, when a human hand or other non-insulating object enters the paper outlet 102, the capacitance value at the paper outlet 102 changes significantly. By detecting the change in capacitance value at the paper outlet 102 through the capacitance detection module, it can be determined whether a human hand or other non-insulating object has entered the paper outlet 102 of the paper pad machine body 1. When an operator accidentally puts their hand or other non-insulating object into the paper outlet 102, the equipment will immediately stop operating and the alarm will sound. The capacitance change can be detected by installing an electrode plate or wrapping at least one turn of electrode foil (such as copper foil, tin foil, aluminum foil, etc., which can be used as electrode materials) on the inner wall or outer periphery of the paper outlet 102. This simplifies the structural design of the paper pad machine body 1 and enables the detection of human body parts and other non-insulating objects in a compact structural space. Moreover, when the electrode foil is wrapped in multiple turns, the surface area of ​​the electrode can be increased, thereby improving the sensitivity of capacitance change detection.

[0058] refer to Figure 3 , Figure 8 , Figure 9 and Figure 13 A power socket 108 and a USB port 109 are installed on the side of the paper pad machine body 1. Both the power socket 108 and the USB port 109 are electrically connected to the circuit board inside the paper pad machine body 1. The power socket 108 is used to connect to an external power source. The paper pad machine body 1 can be powered by an external battery (such as a power bank) connected to the power socket 108, which is convenient for mobile operation. The USB port 109 allows for program updates without disassembling the machine, which is convenient for machine maintenance.

[0059] refer to Figures 1 to 15 In the cushioning paper pad machine of the present invention, the pad material 100 (i.e., raw material consumable) enters the paper inlet 101 of the paper pad machine body 1 after passing over the top of the guide roller 3. After being shrunk and formed by the paper inlet 101, it is pressed and shaped into a cushioning paper pad by the paper pad forming mechanism (upper gear 103 and lower gear 104) inside the paper pad machine body 1 and sent out to the paper outlet 102 of the paper pad machine body 1. The cutting mechanism 116 inside the paper pad machine body 1 ( Figure 9(As shown) The conveyed buffer paper pads are cut to a set length to produce buffer paper pads. The upper gear 103 and lower gear 104 are connected by a non-rigid floating meshing connection. Utilizing the elastic compensation effect of the pre-tension spring 8, the tooth surfaces of the upper gear 103 and lower gear 104 remain in close contact during high-speed operation. Since both ends of the guide roller 3 are conical, when the pad material 100 passes over the top of the guide roller 3, the two ends of the guide roller 3 will pre-deform the sides of the pad material 100 by bending downwards. This differs from the upward folding deformation method of traditional buffer paper pad machines. The pad material entering the paper inlet 101 of the paper pad machine body 1 is guided by the deformation of the guide member 21 of the guide component 2, causing the sides of the pad material 100 to naturally bend downwards. The guide 21, with its curved and arc-shaped sides, guides the pad material to bend downwards smoothly and easily. It also allows the pad material to be pulled more smoothly and with less resistance by the meshing upper gear 103 and lower gear 104. The concave bottom of the guide 21 provides space for the inward folding of the pad material 100 after bending downwards. The protrusion 1011 on the bottom of the paper inlet 101 guides the edges of the pad material 100 to curl upwards. In this invention's buffer paper pad machine, the pad material 100 can be shrunk into the basic shape of a paper pad within the forming channel 113 inside the paper pad machine body 1 by only the short-distance guidance of the guide roller 3 and the guide component 2 in the paper inlet 101. Then, the paper pad forming mechanism inside the paper pad machine body 1... After the upper gear 103 and lower gear 104 are pressed and shaped, a cushioning paper pad is produced. Traditional cushioning paper pad machines have a relatively long forming flow channel and a relatively gentle deformation guidance. In the cushioning paper pad machine of this invention, the guide roller 3 and the T-shaped guide component 2 in the paper inlet 101 can quickly and violently deform and shrink the pad material. After passing through the paper inlet 101, the pad material 100 can shrink from a width of 380mm to between 90mm and 100mm. This allows the pad material 100 after passing through the paper inlet 101 to immediately reach the paper pad forming mechanism inside the paper pad forming machine body 1, thereby effectively shortening the length of the forming flow channel inside the paper pad forming machine body 1. It changes the traditional upward folding method of the pad material and adopts a feeding path where the pad material naturally bends and folds inwards downwards, completing the process with a short-distance guide. Pre-shrinking of the padding material can significantly shorten the length of the forming flow channel, achieving miniaturization of the entire machine. For example, the length from the paper inlet 101 to the paper outlet 102 of the paper pad machine body 1 can be reduced from approximately 840mm to approximately 380mm. In addition, by flipping open the upper cover 105, the electrical components inside the paper pad machine body 1 can be inspected and maintained. After flipping open the flip plate 5, the padding material and debris blocked or stuck in the forming flow channel 113 can be easily removed, achieving quick cleaning of the padding material. After flipping open the dust removal cover 106, the debris generated by the cutting mechanism inside the paper pad machine body 1 when cutting the padding material can be directly cleaned. When the operator accidentally puts his hand or other non-insulated object into the paper outlet 102, the equipment will immediately stop operating and the alarm will sound.

[0060] The above descriptions are merely some embodiments of the present invention. Those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
