Description

Technical Field

[0001] This invention relates to the technical field of material feeding in paper tube processing, and in particular to a material feeding device for paper product processing. Background Technology

[0002] In the paper product processing and production process, paper tubes are a common carrier for winding paper, film and other materials. The cleanliness of their surface directly affects the subsequent packaging quality and usage effect. After the paper tubes are cut and shaped, their surface often has paper scraps, dust and other debris generated during cutting. If they are not cleaned in time, these paper scraps will contaminate the products that are subsequently wound, or fall off during packaging and stacking, affecting the cleanliness of the production environment and the appearance quality of the products.

[0003] Traditional paper tube conveying devices typically only have simple conveying functions, transferring paper tubes from the cutting station to the next process via conveyor belts or rollers. Most existing conveying equipment lacks an effective online cleaning mechanism, requiring manual cleaning or separate cleaning stations to remove paper scraps from the paper tube surface. This increases the process flow and labor costs, reduces production efficiency, and the impact force when the paper tube falls onto the conveyor belt is relatively large, which can easily cause damage to the ends of the paper tube or equipment vibration, affecting the stability and service life of the equipment. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0032] Example 1, referring to Figures 1 to 8This is the first embodiment of the present invention. This embodiment provides a feeding device for paper product processing and production. The feeding device for paper product processing and production uses a structure of support rollers 7 and negative pressure holes 8 to form a local low pressure at the negative pressure holes 8 by utilizing high-speed airflow to achieve online automatic cleaning of paper scraps on the surface of the paper tube. The sliding sleeve 31 and the support rod 32 cooperate with the throttling hole 33 to automatically adjust the spacing of the support rollers 7 and buffer the impact of the paper tube falling by utilizing air pressure changes. The adjusting gear 71 meshes with the internal gear ring 72 to make the support rollers 7 rotate during the revolution and conveying process, so as to achieve full-square cleaning of the paper tube. Cleanliness is achieved through the following: the support roller 115 and the swing link 114 adaptively fit the diameter of the paper tube under the action of the torsion spring 116, ensuring the paper tube stands stably and naturally creating gaps to avoid collisions; the stabilizing frame 117 and the second conveyor belt 118 are driven by the hydraulic link 119 to form an upper and lower clamping conveyor, and the guide assembly 1110 ensures synchronous lifting to ensure smooth conveying; the second drive component 10 draws power from the central shaft of the air pump 92 to achieve integration of air supply and conveying power; the end cap 12 and the net bag collect paper scraps to keep the environment clean; the guide rod 73 and the connecting plate 74 separate the flow channels to balance the adsorption force.

[0033] Specifically, such as Figure 1 As shown, a guide plate is fixedly installed on one side of the upper end of the support 1. The guide plate overlaps with the discharge port of the paper tube dividing device. When the paper tube is discharged, it guides the paper tube to the support roller 7. Both sides of the support 1 are rotatably equipped with drive disks 2; air chambers 3 are set inside the drive disks 2. The air chambers 3 of the two drive disks 2 are connected to each other through connecting pipes 4; there are multiple linear grooves 5, which are arranged in a ring array around the air chambers 3 and along the radial direction of the drive disks 2 inside the drive disks 2; and a rotating part 6 is slidably set in the linear grooves 5.

[0034] Specifically, the support roller 7 is rotatably positioned between two corresponding rotating parts 6 on both sides and is rotatably connected to the rotating parts 6 via bearings, allowing them to rotate relative to each other. A support gap is formed between adjacent support rollers 7 to support the paper tube. In use, after the paper tube is cut, it falls from the top into the support gap between the two adjacent support rollers 7. The support roller 7 has a hollow structure and is open at both ends. Multiple negative pressure holes 8 are opened on the outer peripheral wall of the support roller 7. The drive motor 91 is started, and the drive motor 91 drives the air pump 92 to work. The air pump 92 sends compressed air into the air chamber 3 through the connecting pipe 4. Since the air chambers 3 of the two drive discs 2 are connected to each other through the connecting pipe 4, the compressed air enters the interior of the support rollers 7 on both sides evenly. The airflow is quickly discharged from the other end of the support roller 7. During this process, according to Bernoulli's principle, the high-speed airflow creates a local low pressure at the negative pressure hole 8, thereby drawing paper scraps from the surface of the paper tube into the negative pressure hole 8 and discharging them from the end of the support roller 7 with the airflow. This achieves automatic cleaning of paper scraps on the surface of the paper tube, avoiding the tediousness of manual cleaning and effectively improving the cleanliness of subsequent packaging or palletizing.

[0035] Specifically, the first driving component 9 includes a drive motor 91 and an air pump 92. The drive motor 91 is fixedly connected to the side wall of the support 1, and the air pump 92 is drivenly connected to the motor shaft of the drive motor 91. The exhaust port of the air pump 92 is connected to the air chamber 3.

[0036] Specifically, the second driving component 10 is connected to the driving disk 2 for driving the driving disk 2 to rotate. The second driving component 10 drives the driving disk 2 to rotate slowly around its axis, causing all the support rollers 7 to revolve, so that the paper tube rotates during the cleaning process, thereby improving the cleaning efficiency.

[0037] Example 2, refer to Figures 2-8 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, it also includes sliding sleeves 31 and support rods 32. There are multiple sliding sleeves 31, which are evenly arranged on the outer periphery of the air cavity 3, and the interior of the sliding sleeves 31 is connected to the interior of the air cavity 3. The bottom end of the support rod 32 is slidably disposed inside the top end of the sliding sleeve 31, and the top end of the support rod 32 is fixedly connected to the rotating part 6. When the air pump 92 fills the air cavity 3 with compressed air, the air not only enters the support roller 7, but also enters each sliding sleeve 31. The increased air pressure inside the sliding sleeve 31 pushes the support rod 32 outward. The support rod 32 drives the rotating part 6 to slide outward along the linear groove 5, thereby moving the support rollers 7 on both sides away from each other and widening the support gap. This design allows the support rollers 7 to automatically unfold when there is no paper tube, making it easier for the paper tube to fall into the gap. When the paper tube falls and hits the support roller 7, the impact force is transmitted to the support rod 32 through the support roller 7, causing the support rod 32 to compress the gas inside the sliding sleeve 31, achieving buffering and depressurization, effectively preventing the paper tube from being damaged by hard impact, and also protecting the support rollers 7 and transmission components, extending the service life of the equipment.

[0039] Specifically, the support rod 32 is sealed and slides in a sliding fit with the inner wall of the sliding sleeve 31. A throttling orifice 33 is provided at the connection between the sliding sleeve 31 and the air cavity 3. The presence of the throttling orifice 33 gives the change in air pressure inside the sliding sleeve 31 a certain degree of damping. The impact force of the falling paper tube is transmitted to the support rod 32 through the support roller 7, forcing the support rod 32 to retract quickly. At this time, the gas inside the sliding sleeve 31 is compressed and can only be slowly discharged into the air cavity 3 through the small throttling orifice 33. This forms a damping back pressure inside the sliding sleeve 31, effectively absorbing the impact energy and achieving buffer protection for the paper tube and the equipment. When the support rod 32 extends, the gas enters through the throttling orifice 33, which also limits the extension speed, making the unfolding action of the support roller 7 smooth and controllable, avoiding violent shaking caused by sudden changes in air pressure, and improving the stability of equipment operation and the accuracy of paper tube positioning.

[0040] Specifically, it also includes an adjusting gear 71 and an internal gear ring 72. The adjusting gear 71 is fixedly connected to one end of the support roller 7, and the internal gear ring 72 is fixedly set on the side wall of the support 1 and meshes with the adjusting gear 71. When the drive disk 2 drives the support roller 7 to revolve, since the internal gear ring 72 is fixed, the adjusting gear 71 is forced to rotate under the action of meshing with the internal gear ring 72, thereby driving the support roller 7 to rotate around its own axis, so that the paper tube passively rotates in the support gap. Its entire circumferential surface can be aligned with the negative pressure hole 8 in sequence, ensuring that paper scraps from all parts of the paper tube can be effectively sucked in, achieving all-round cleaning, avoiding cleaning dead corners, and improving the cleanliness consistency of the paper tube surface.

[0041] Specifically, it also includes a conveyor frame 11, which is disposed on one side of the support 1, including an outer frame 111, which is fixedly disposed on one side of the support 1 by multiple connecting rods; a first conveyor belt 112, which is disposed at the bottom of the inner side of the outer frame 111; multiple mounting slots 113, which are opened on both sides of the first conveyor belt 112 along the conveying direction of the first conveyor belt 112, and the spacing between two adjacent mounting slots 113 is equal; a swing link 114, which is rotatably connected to the inside of the mounting slot 113; a support roller 115, which is rotatably disposed between the top ends of two corresponding swing links 114 on both sides; and a torsion spring 116, which is disposed at the connection between the swing link 114 and the inner wall of the mounting slot 113, and when the cleaned paper tube passes from the support... When the paper tube rolls down from the idler roller 7 onto the first conveyor belt 112, it first contacts the support rollers 115 on both sides. Under the action of gravity, the paper tube presses down on the support rollers 115, causing the swing link 114 to swing outward against the elastic force of the torsion spring 116. The support rollers 115 then open and adaptively fit the diameter of the paper tube. The restoring force of the torsion spring 116 ensures that the support rollers 115 always apply a certain clamping force to the paper tube, ensuring that the paper tube stands stably on the first conveyor belt 112 and does not tip over. At the same time, since the spacing between adjacent mounting slots 113 is equal, a uniform interval is formed between adjacent support rollers 115, which naturally creates gaps between the falling paper tubes, preventing the paper tubes from colliding with each other during the conveying process, ensuring neat arrangement, and providing convenience for subsequent bundling or stacking.

[0042] Furthermore, such as Figure 1 As shown, a transfer assembly is provided in the gap between the support 1 and the feeder 11. The assembly includes two side plates, which are rotatably connected to the side walls of the two supports 1 respectively. Several small-diameter and densely arranged guide rollers are rotatably arranged between the two side plates, so that paper tubes of different specifications can roll on the surface of the transfer assembly. At the same time, the side plates and the supports 1 can be fixed at different angles by bolts to form a downward angle, so that the paper tube can roll down from the support roller 7 to the surface of the transfer assembly, and then roll through the transfer assembly to the surface of the first conveyor belt 112.

[0043] Specifically, the feeding frame 11 also includes a stabilizing frame 117, which is slidably disposed on the upper inner side of the outer frame 111; a second conveyor belt 118, which is sleeved on the outer periphery of the stabilizing frame 117; and four hydraulic connecting rods 119, which are respectively disposed at the four corners of the stabilizing frame 117. The outer shell of the hydraulic connecting rod 119 is fixedly connected to the top of the outer frame 111, and the piston rod end of the hydraulic connecting rod 119 is fixedly connected to the stabilizing frame 117. During the process of the paper tube being conveyed by the first conveyor belt 112, the hydraulic connecting rod 119 extends and pushes the stabilizing frame 117 downward, so that the second conveyor belt 118 presses against the upper surface of the paper tube. The first conveyor belt 112 and the second conveyor belt 118 run synchronously to form an upper and lower clamping conveying, which effectively prevents the paper tube from rolling or deviating when accelerating or decelerating, ensuring smooth conveying. The flexible contact of the second conveyor belt 118 will not damage the surface of the paper tube, and at the same time, it can adapt to paper tubes of different diameters, improving the versatility of the device.

[0044] Specifically, the feeding rack 11 also includes a guide assembly 1110 disposed at the top of the outer frame 111, including a rotating shaft 11101 rotatably connected to the top of the outer frame 111; two guide gears 11102 fixedly disposed on the outer periphery of the rotating shaft 11101; and a guide rack 11103 fixedly disposed on the stabilizing frame 117. The guide rack 11103 meshes with the guide gears 11102. When the hydraulic connecting rod 119 drives the stabilizing frame 117 to rise and fall, the guide racks 11103 on both sides of the stabilizing frame 117 drive the guide gears 11102 to rotate. Since the gears on both sides are connected through the same rotating shaft 11101, the left and right sides of the stabilizing frame 117 rise and fall synchronously, avoiding tilting and jamming, and ensuring that the second conveyor belt 118 is always parallel to the first conveyor belt 112, thereby applying uniform pressure to the paper tube and improving the conveying stability.

[0045] Specifically, the second driving component 10 includes a connecting shaft 101, which is fixedly connected to the central shaft of the air pump 92, a first pulley 102 fixedly connected to the connecting shaft 101, and a second pulley 103 fixedly connected to the driving disc 2. A transmission belt 104 is sleeved between the first pulley 102 and the second pulley 103. In use, the drive motor 91 drives the air pump 92 and the second driving component 10 simultaneously. The rotation of the central shaft of the air pump 92 drives the connecting shaft 101 to rotate. Power is transmitted to the driving disc 2 through the first pulley 102, the transmission belt 104, and the second pulley 103, realizing the slow revolution of the driving disc 2. This allows a single motor to simultaneously complete the functions of air supply and delivery, simplifying the power system, reducing energy consumption and manufacturing costs, and enabling flexible adjustment of the speed through belt drive to adapt to different production rhythms.

[0046] Specifically, an end cap 12 is fixedly installed on one side of the support 1, and the position of the end cap 12 corresponds to the discharge end of the support roller 7. A mesh bag is detachably connected to the outer periphery of the end cap 12. The airflow discharged from the end of the support roller 7 carries paper scraps and blows them toward the end cap 12. The end cap 12 blocks and changes the direction of the airflow, causing the paper scraps to fall into the mesh bag for collection, preventing the paper scraps from flying around and polluting the environment. The detachable design of the mesh bag facilitates regular cleaning and keeps the working area clean. At the same time, a protective switch (not shown in the figure) is installed at the end cap 12. This switch is connected in series in the control circuit of the first drive unit 9. When the end cap 12 is removed, the micro switch is disconnected, and the first drive unit 9 cannot be started, thereby ensuring operational safety.

[0047] Specifically, the support roller 7 is provided with a guide rod 73 inside, and a plurality of connecting plates 74 are fixedly provided on the outer periphery of the guide rod 73. The connecting plates 74 are located between two adjacent negative pressure holes 8 and are used to separate the negative pressure holes 8 in the same linear direction. The guide rod 73 and the connecting plates 74 divide the inside of the support roller 7 into a plurality of independent flow channels. Each flow channel corresponds to a row of negative pressure holes 8. When the airflow enters from one end, due to the separation of the flow channels, the airflow is evenly distributed along each flow channel, avoiding short-circuiting or deviating to one side of the airflow, so that the adsorption force at each negative pressure hole 8 is balanced, thereby ensuring that paper scraps on all parts of the paper tube surface can be effectively sucked in, and improving the uniformity of the cleaning effect.

[0048] During use, the paper tube falls into the support gap, the first drive unit 9 is activated, the airflow enters the support roller 7 through the air cavity 3, the negative pressure hole 8 adsorbs paper scraps and discharges them with the airflow, at the same time the air pressure pushes the support rod 32 to unfold the support roller 7 and buffer the impact; the drive disk 2 revolves to transport the paper tube, the adjusting gear 71 cooperates with the internal gear ring 72 to make the support roller 7 rotate, achieving all-round cleaning; the cleaned paper tube falls into the feed rack 11, is adaptively clamped by the support roller 115, and is stably output through the first conveyor belt 112 and the second conveyor belt 118.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
