Description

Technical Field

[0001] This utility model application relates to the field of paper tube slotting technology, and in particular to a paper tube slotting device. Background Technology

[0002] like Figure 1 As shown, during the fiber winding process, the paper tube, as an important load-bearing tool, typically requires the machining of lead-in grooves and / or tail-out grooves on its outer wall to meet the needs of fiber fixation and guidance. Lead-in grooves guide the fiber positioning at the initial stage of winding, while tail-out grooves secure the fiber tail at the end of winding, thereby ensuring the stability of the winding process and product quality.

[0003] Currently, the grooving process of paper tubes mainly relies on manual operation. Workers hold the paper tubes and perform grooving through manual or semi-automatic equipment. However, this processing method has the following significant drawbacks: (1) Low processing efficiency: The grooving speed of manual operation is relatively slow, which is difficult to meet the needs of mass production. Especially in high-efficiency fiber winding production lines, paper tube grooving becomes a bottleneck restricting the overall production efficiency; (2) High labor intensity: Workers need to hold the paper tubes for a long time to perform repetitive operations, which can easily lead to physical fatigue. This not only affects the health of workers, but may also cause a decrease in grooving accuracy and unstable processing quality due to fatigue.

[0004] Therefore, there is an urgent need for a paper tube slotting device to overcome the shortcomings of existing technologies, improve the automation level of paper tube processing, reduce reliance on manual operation, and meet the demand of modern fiber winding production lines for high-efficiency paper tubes.

The gear unit, gear flange 105, and stop plate can be connected together using common fasteners such as bolts.

[0030] In this utility model application, the first toothed disc 701 and the second toothed disc 1072 are connected together by multiple connecting posts 1073 to form a toothed disc unit 107. The first toothed disc 1071 and the second toothed disc 1072 work together to support the two sides of the paper tube to be slotted or the two sides after slotting. The stop disc 106 is located outside the first toothed disc 1071 and is fixedly installed on the first rotating shaft 104 to prevent the first toothed disc 1071 from sliding along the axial direction of the first rotating shaft 104.

[0032] In this utility model application, firstly, the first toothed disc 1071 is provided with a plurality of first arc-shaped grooves 10711, and the second toothed disc 1072 is provided with a plurality of second arc-shaped grooves 10721. The first arc-shaped grooves and the second arc-shaped grooves have the same structure and position (e.g., circumferential position). The first arc-shaped grooves 10711 and the second arc-shaped grooves 10721 are aligned, so that the first arc-shaped grooves 10711 and the second arc-shaped grooves 10721 jointly support the paper tube to be slotted or the paper tube after slotting. The radius of the first arc-shaped grooves and the second arc-shaped grooves can be designed to match the shape of the paper tube to be slotted, so that the first toothed disc 1071 and the second toothed disc 1072 can stably support the paper tube to be slotted or the paper tube after slotting. In addition, the first rotating shaft 104 can be connected to the first toothed disc and the second toothed disc using the key connection method in the existing mechanical field, so that the first toothed disc and the second toothed disc can be connected to the first rotating shaft.

[0033] Optionally, the first gear plate 1071 is provided with multiple first connecting holes 10713, the second gear plate is provided with multiple second connecting holes, the stop plate 106 is provided with multiple mounting holes, and the gear plate flange 105 is provided with multiple through holes. Fasteners pass through the mounting holes, the first connecting holes, the through holes, and the second connecting holes.

[0034] In this utility model application, fasteners (such as bolts or screws) can be passed sequentially through the mounting holes of the stop plate 106, the first connecting hole of the first gear plate 1071, the through hole of the gear plate flange 105, and the second connecting hole of the second gear plate 1072. Then, nuts or the like are used to firmly connect these components together, thus connecting the second gear plate 1072, the gear plate flange 105, the first gear plate 1071, and the stop plate 106 together. The entire assembly and disassembly process does not require complicated tools, which is convenient for daily maintenance or replacement of components.

[0035] Optionally, the clamping release unit 200 includes: a second motor 201, a second mounting plate 202, a gear 203, a first moving rod 204, a second moving rod 205, a third moving rod 206, a connecting block 207, a first top head 2091, and a second top head 2101; the second motor 201 is connected to the first support plate 501 through the second mounting plate 202, the output shaft of the second motor 201 is connected to the gear 203, the first moving rod 204 is provided with a first tooth groove, the second moving rod 205 is provided with a second tooth groove, the gear 203 meshes with the first tooth groove and the second tooth groove, the connecting block 207 is connected to the second moving rod 205 and the third moving rod 206, the first moving rod 204 is connected to the first top head 2091, and the second top head 2101 is connected to the third moving rod 206.

[0036] In this utility model application, one side of the connecting block 207 can be connected to the second moving rod 205 via the first fastener 2071, and the other side of the connecting block 207 can be connected to the third moving rod 206 via the second fastener 2061. The first fastener 2061 and the second fastener 2071 can be fasteners such as flanges and nuts. The second motor 201 drives the gear 203 to rotate, and the gear 203 meshes with the first tooth groove of the first moving rod 204 and the second tooth groove of the second moving rod 205, driving the first moving rod 204 to move, the second moving rod 205 to move, and the third moving rod to move. 206 moves; specifically, the second motor 201 drives the gear 203 to rotate forward and backward, causing the first moving rod 204 and the third moving rod 206 to move closer or further apart. The first moving rod 204 is connected to the first mandrel 2091, and the third moving rod 206 is connected to the second mandrel 2101. Thus, the first mandrel and the second mandrel can achieve clamping or releasing actions by moving the first moving rod 204 and the third moving rod 206 closer or further apart. A clamping action at least means clamping the paper tube to be slotted, and a releasing action at least means releasing or loosening the paper tube after slotting. Specifically, the two cases of the second motor rotating forward and backward are as follows: When the second motor 201 rotates forward, the gear 203 rotates in one direction (e.g., clockwise or counterclockwise). The gear 203 meshes with the first and second tooth slots. The gear 203 drives the first moving rod 204 and the second moving rod 205 to move in opposite directions. Since the second moving rod 205 is connected to the third moving rod 206 through the connecting block 207, the third moving rod 206 also moves synchronously. Accordingly, the first moving rod 204 and the third moving rod 206 will move towards each other. However, the first moving rod 204 drives the first top head, and the third moving rod 206 drives the second top head, so that the first top head and the second top head approach and clamp the paper tube to be slotted, completing the clamping action of the paper tube to be slotted.

[0037] When the second motor 201 reverses, the gear 203 rotates in the opposite direction (e.g., counterclockwise or clockwise). The reverse rotation of the gear 203 drives the first moving rod 204 and the second moving rod 205 to move in opposite directions. The third moving rod 206 also moves in the opposite direction due to the action of the connecting block 207. Accordingly, the first moving rod 204 and the third moving rod 206 will move away from each other. However, the first moving rod 204 drives the first top head, and the third moving rod 206 drives the second top head, so that the first top head and the second top head move away from the released paper tube after the slotting is completed, thus completing the release action of the paper tube after the slotting is completed.

[0038] Optionally, a first bushing 2092 is installed on the first support plate 501, a second bushing 2102 is installed on the second support plate 502, a first moving rod 204 slides relative to the first bushing 2092, and a third moving rod 206 slides relative to the second bushing 2102.

[0039] In this utility model application, guide sleeves 208 can be provided on both the first support plate 501 and the second support plate 502. The guide sleeves 208 guide the movement of the second moving rod 205. The first moving rod 204 and the third moving rod 206 can move linearly through the first bushing 2092 and the second bushing 20102 respectively, driven by the second motor 201 and the gear 203.

[0040] Optionally, the grooving unit 300 includes: a third motor 301, a reducer 302, a third mounting plate 303, a coupling, a second rotating shaft 304, a cutting blade, a bearing 308, and a mounting plate 309; the output shaft of the third motor 301 is connected to the reducer 302, the reducer 302 is connected to the first support plate 501 through the third mounting plate 303, the output shaft of the reducer 302 is connected to one side of the second rotating shaft 304 through the coupling, multiple cutting blades are connected to the second rotating shaft 304, the other side of the second rotating shaft 304 is connected to the bearing 308, the bearing 308 is connected to the mounting plate 309, and the mounting plate 309 is connected to the second support plate 502.

[0041] In some embodiments, the third motor 301 is selected from the MS1H1 series motor, and the reducer 302 can be selected from the MRV025 series reducer, etc.

[0042] In this utility model application, the third motor 301 drives the output shaft of the reducer 302 to rotate. The output shaft of the reducer 302 is connected to the second rotating shaft 304 through a coupling, thereby driving the second rotating shaft 304 and the cutting blade to rotate. The cutting blade can slot the paper tube to be slotted.

[0043] Optionally, multiple cutting blades are provided, including a first cutting blade 305 and a second cutting blade 306. The first cutting blade 305 includes a first cutting edge 3051 with a radius of R1, a second first cutting edge 3052 with a radius of R2, and a first mounting hole 3053. The second cutting blade 306 includes a second cutting edge 3061 with a radius of R3, a second cutting edge 3062 with a radius of R4, and a second mounting hole 3063. The second rotating shaft 304 passes through the first mounting hole 3053 and the second mounting hole 3063.

[0044] In some embodiments, the first cutting edge 3051 may contact the surface of the paper tube to be slotted, the second cutting edge 3052 may not contact the surface of the paper tube to be slotted, the first cutting edge 3061 may contact the surface of the paper tube to be slotted, and the second cutting edge 3062 may not contact the surface of the paper tube to be slotted. As the cutting blade rotates, the first cutting edge and the second cutting edge can cut into the interior of the paper tube to be slotted to form the desired groove. The depth and shape of the groove can be determined by the radius of the first cutting edge, the radius of the second cutting edge, and the installation position on the second rotating shaft 304.

[0045] Optionally, multiple first mounting posts 1062 connect the first support plate 501 and the first baffle 1061, and multiple second mounting posts 1072 connect the second support plate 502 and the second baffle 1062. The gear unit 107 is located between the first baffle 1061 and the second baffle 1062. The first baffle 1061 has a first through hole, and the second baffle 1062 has a second through hole. The first top head 2091 can pass through the first through hole, and the second top head 2101 can pass through the second through hole.

[0046] In this utility model application, the first through hole corresponds to the first top head, and the second through hole corresponds to the second top head, which guides the movement of the first top head and the second top head. The first top head and the second top head can clamp the paper tube to be slotted.

[0047] Optionally, the other side of the second rotating shaft 304 is connected to the bearing 308 via a connector 307. The connector 307 includes a bearing seat 3071 and a connecting shaft 3072. One side of the bearing seat 3071 is connected to the second rotating shaft 304, and the other side of the bearing seat 3071 is connected to the connecting shaft 3072. The connecting shaft 3072 is connected to the bearing 308.

[0048] In this utility model application, the third motor 301 drives the second rotating shaft 304 to rotate. The second rotating shaft 304 is fastened to the connecting shaft seat 3071. The rotational motion of the second rotating shaft 304 is transmitted to the connecting shaft 3072. The connecting shaft 3072 is mounted on the mounting plate 309 through the bearing 308. The mounting plate 309 is fixed on the second support plate 502, providing a mounting base for the bearing 308.

[0049] The working method of the paper tube slotting device of this utility model application is as follows: First, when the paper tube to be slotted is loaded, the operator manually or through the conveying mechanism (such as a common conveyor chain, common conveyor belt, etc.) set in front of the loading and unloading unit 100 to feed the paper tube to be slotted into the toothed disc unit 107. The paper tube to be slotted is placed in the first arc-shaped groove 10711 of the first toothed disc 1071 and the second arc-shaped groove 10721 of the second toothed disc 1072 in the toothed disc unit 107. The first toothed disc 1071 and the second toothed disc 1072 respectively support the two sides of the paper tube to be slotted, and thus the paper tube to be slotted is carried by the toothed disc unit 107. The first motor 101 rotates, driving the toothed disc unit 107 to rotate, and the paper tube to be slotted moves between the first top head 2091 and the second top head 2101. Next, when the second motor 201 rotates forward, the gear 203 rotates in one direction and meshes with the first and second tooth slots. The gear 203 drives the first moving rod 204 and the second moving rod 205 to move in opposite directions. Since the second moving rod 205 is connected to the third moving rod 206 through the connecting block 207, the third moving rod 206 also moves synchronously. Accordingly, the first moving rod 204 and the third moving rod 206 will move closer to each other. However, the first moving rod 204 drives the first top head 2091, and the third moving rod 206 drives the second top head 2101, so that the first top head 2091 and the second top head 2101 approach and clamp the paper tube to be slotted, completing the clamping action of the paper tube to be slotted, so that the paper tube will not move left or right during the subsequent cutting process. Then, the third motor 301 drives the reducer to reduce speed, and the second rotating shaft 304 rotates under the drive of the reducer 302, driving multiple cutting blades (such as the first cutting blade and the second cutting blade) mounted on the second rotating shaft 304 to rotate synchronously. Based on the clamping of the paper tube to be slotted, the multiple cutting blades contact the surface of the paper tube to be slotted and cut it, forming the required groove on the surface of the paper tube to be slotted, thereby completing the slotting of the paper tube by multiple cutting blades. Next, when the second motor 201 reverses, the gear 203 rotates in the opposite direction. The reverse rotation of the gear 203 drives the first moving rod 204 and the second moving rod 205 to move in opposite directions. The third moving rod 206 also moves in the opposite direction due to the action of the connecting block 207. Correspondingly, the first moving rod 204 and the third moving rod 206 will move away from each other. However, the first moving rod 204 drives the first push head, and the third moving rod 206 drives the second push head, so that the first push head and the second push head move away from the released paper tube after the slotting is completed, thus completing the release action of the paper tube after the slotting is completed.

[0050] Finally, the first motor 101 rotates again, driving the toothed disc unit 107 to rotate, which in turn drives the grooved paper tube to rotate. Due to its own gravity, the grooved paper tube leaves the toothed disc unit 107 and can fall into the collection box for collection.
