Description

Technical Field

[0001] This utility model relates to the field of paper processing machinery technology, and more specifically, to a needle roller structure for machining. Background Technology

[0002] A needle roller is a cylindrical industrial component with fine steel needles evenly arranged on its surface. It is usually made of a metal substrate and is precision machined to ensure the accuracy of needle tip arrangement and wear resistance. Its working principle is to achieve functions such as loosening, combing or texturing by rotating and contacting the material surface. It is widely used in industries such as textiles, papermaking and leather processing and is one of the core instruments in the field of material surface treatment.

[0003] When processing waxed paper, operators often use needle rollers to create small holes in the paper. However, while existing needle rollers have basic waxed paper processing functions, they generally cannot remove and replace the nylon layer with inserted needles. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a needle roller structure for machining, which has the advantage of a removable needle insert nylon layer.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a needle roller structure for machining, comprising a round shaft, a steel layer movably sleeved on the outer surface of the round shaft, a needle-inserting nylon layer fixedly connected to the outer surface of the steel layer, a cavity opened on the right side of the inside of the round shaft, a fixing block fixedly connected to the left side of the inner surface of the cavity, a threaded rod movably sleeved on the inner surface of the right side of the round shaft, the left end of the threaded rod sequentially penetrating the round shaft and the fixing block and extending into the interior of the fixing block, a movable block threadedly sleeved on the outer surface of the threaded rod, the outer surface of the movable block movably connected to the inner surface of the cavity, a connecting rod hinged to the left surface of the movable block, and a locking block hinged to the other end of each connecting rod, the number of locking blocks being three, the outer surfaces of all three locking blocks being movably connected to the inner surface of the cavity, the outer ends of all three locking blocks penetrating the round shaft and extending to the outer side of the round shaft, and the left surfaces of all three locking blocks being movably connected to the right surface of the steel layer.

[0006] As a preferred embodiment of this utility model, a limiting disc is fixedly connected to the left end of the threaded rod, and the outer surface of the limiting disc is movably connected to the inner surface of the fixing block.

[0007] As a preferred embodiment of this utility model, a limiting strip is fixedly connected to the outer surface of the circular shaft, and the outer surface of the limiting strip is movably connected to the inner surface of the steel layer.

[0008] As a preferred embodiment of this utility model, two base plates are movably connected to the left and right sides of the outer surface of the circular shaft. The upper surfaces of the two base plates are respectively movably connected to a first pressure plate and a second pressure plate. The outer surface dimensions of the first pressure plate and the second pressure plate are completely identical. Circular grooves are formed on the left and right sides of the outer surface of the circular shaft between the first pressure plate and the second pressure plate. Semi-circular sliding plates are movably connected to the inner surfaces of the circular grooves. There are two semi-circular sliding plates, and the outer surfaces of the two semi-circular sliding plates are respectively fixedly connected to the first pressure plate and the second pressure plate.

[0009] As a preferred embodiment of this utility model, a drive motor is fixedly installed on the inner surface of the top of the second pressure plate, a rotating shaft is fixedly sleeved at the other end of the output shaft of the drive motor, and an active rod is fixedly sleeved on the outer surface of the rotating shaft.

[0010] As a preferred embodiment of this utility model, the other end of the driving rod is hinged to a driven rod, the other end of the driven rod is movably sleeved with a sleeve bolt, the bottom end of the outer surface of the sleeve bolt is threaded with a movable plate, the right surface of the movable plate is movably connected to the left end of the steel layer, and the inner surface of the movable plate is movably sleeved with the outer surface of the round shaft.

[0011] As a preferred technical solution of this utility model, long bolts are movably sleeved on the upper surfaces of the first pressure plate and the second pressure plate. The bottom ends of the long bolts pass through the first pressure plate, the second pressure plate and the bottom plate in sequence and extend into the interior of the bottom plate. The outer surface and the inner surface of the bottom plate are threaded together.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting a fixed block, a threaded rod, a movable block, a connecting rod, and a locking block, allows the operator to rotate the threaded rod. When the operator rotates the threaded rod, the outer surface of the threaded rod will drive the movable block, causing the movable block to move to the right. At this time, the three connecting rods will rotate along with the movement of the movable block, and the other end of the connecting rod will drive the locking block, causing the three locking blocks to move in opposite directions. Finally, when the three locking blocks contact the fixed block, the three locking blocks will retract into the cavity. At this time, the locking blocks will no longer block the steel layer, thus allowing the steel layer and the nylon layer of the insert pin to be pulled out from the outer surface of the round shaft.

[0014] 2. This utility model, by setting a rotating shaft, a driving rod, a driven rod, a sleeve bolt, and a movable plate, allows the rotating shaft and driving rod to start rotating when the drive motor starts running. At this time, the other end of the driving rod will drive the driven rod, causing the driven rod to also start rotating. The other end of the driven rod will then drive the sleeve bolt, causing the sleeve bolt and the movable plate to move left and right along the outer surface of the circular shaft. At this time, the distance from the right surface of the movable plate to the left end of the connecting rod will change, thus allowing steel layers of different lengths to be fitted onto the outer surface of the circular shaft.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1 to 7 As shown, this utility model provides a needle roller structure for machining, including a round shaft 1, a steel layer 2 movably sleeved on the outer surface of the round shaft 1, a needle nylon layer 3 fixedly connected to the outer surface of the steel layer 2, a cavity 4 opened on the right side inside the round shaft 1, a fixing block 5 fixedly connected to the left side of the inner surface of the cavity 4, a threaded rod 6 movably sleeved on the inner surface of the right side of the round shaft 1, the left end of the threaded rod 6 passing through the round shaft 1 and the fixing block 5 in sequence and extending into the interior of the fixing block 5, a movable block 7 threadedly sleeved on the outer surface of the threaded rod 6, the outer surface of the movable block 7 movably connected to the inner surface of the cavity 4, a connecting rod 8 hinged to the left surface of the movable block 7, and a locking block 9 hinged to the other end of each connecting rod 8, the number of locking blocks 9 being three, the outer surfaces of the three locking blocks 9 being movably connected to the inner surface of the cavity 4, the outer ends of the three locking blocks 9 passing through the round shaft 1 and extending to the outer side of the round shaft 1, and the left surfaces of the three locking blocks 9 being movably connected to the right surface of the steel layer 2.

[0025] When the threaded rod 6 starts to rotate, the moving block 7 will start to move to the left under the drive of the thread of the threaded rod 6. At this time, the three connecting rods 8 will start to rotate with the movement of the moving block 7. At the same time, the other end of the connecting rod 8 will drive the locking block 9, thereby causing the three locking blocks 9 to start to move in opposite directions.

[0026] Among them, the left end of the threaded rod 6 is fixedly connected to the limiting disc 10, and the outer surface of the limiting disc 10 is movably connected to the inner surface of the fixing block 5.

[0027] The design of the limiting disc 10 ensures that the threaded rod 6 will not detach from the inner surfaces of the moving block 7 and the fixed block 5.

[0028] Among them, the outer surface of the round shaft 1 is fixedly connected to the limiting strip 11, and the outer surface of the limiting strip 11 is movably connected to the inner surface of the steel layer 2.

[0029] The design of the limiting strip 11 allows the steel layer 2 and the pin nylon layer 3 to rotate together with the round shaft 1.

[0030] The outer surface of the circular shaft 1 is movably connected to two base plates 12 on both the left and right sides. The upper surfaces of the two base plates 12 are movably connected to a first pressure plate 13 and a second pressure plate 14, respectively. The outer surface dimensions of the first pressure plate 13 and the second pressure plate 14 are exactly the same. The outer surfaces of the circular shaft 1 are provided with circular grooves 15 between the first pressure plate 13 and the second pressure plate 14 on both the left and right sides. The inner surfaces of the circular grooves 15 are movably connected to two semi-circular sliding plates 16. The outer surfaces of the two semi-circular sliding plates 16 are fixedly connected to the first pressure plate 13 and the second pressure plate 14, respectively.

[0031] The design of the circular groove 15 and the semi-circular sliding plate 16 can prevent the circular shaft 1 from sliding left and right between the first pressure plate 13 and the second pressure plate 14.

[0032] Among them, a drive motor 17 is fixedly installed on the inner surface of the top of the second pressure plate 14, and a rotating shaft 18 is fixedly sleeved on the other end of the output shaft of the drive motor 17. An active rod 19 is fixedly sleeved on the outer surface of the rotating shaft 18.

[0033] When the drive motor 17 starts running, the rotating shaft 18 and the drive rod 19 will start to rotate.

[0034] Among them, the other end of the driving rod 19 is hinged to the driven rod 20, the other end of the driven rod 20 is movably sleeved with the sleeve bolt 21, the bottom end of the outer surface of the sleeve bolt 21 is threaded with the movable plate 22, the right surface of the movable plate 22 is movably connected to the left end of the steel layer 2, and the inner surface of the movable plate 22 is movably sleeved with the outer surface of the round shaft 1.

[0035] The design of the driving rod 19, driven rod 20, sleeve bolt 21 and movable plate 22 ensures that the sleeve bolt 21 will not rotate with the round shaft 1. At the same time, the thread design of the sleeve bolt 21 allows the sleeve bolt 21 to be pulled out from inside the movable plate 22.

[0036] Among them, the upper surfaces of the first pressure plate 13 and the second pressure plate 14 are movably fitted with long bolts 23. The bottom ends of the long bolts 23 pass through the first pressure plate 13, the second pressure plate 14 and the base plate 12 in sequence and extend into the interior of the base plate 12. The outer surface of the base plate 12 and the inner surface of the base plate 12 are threaded together.

[0037] The design of the long bolt 23 serves to fix the first pressure plate 13 or the second pressure plate 14 above the base plate 12.

[0038] Working principle and usage process of this utility model:

[0039] When the operator needs to remove the entire steel layer 2, the operator first removes the connecting bolt 21, then removes the long bolt 23, the entire first pressure plate 13 and the entire second pressure plate 14, and removes the entire round shaft 1 from inside the base plate 12. At this time, the base plate 12 will no longer block the steel layer 2 and the insert nylon layer 3. Then the operator rotates the threaded rod 6. As the threaded rod 6 rotates, the moving block 7 will start to move to the right under the drive of the threaded rod 6. At the same time, the connecting rod 8 will start to rotate due to the movement of the moving block 7. At this time, the other end of the connecting rod 8 will drive the locking block 9, so that the three locking blocks 9 will start to move in the direction of the moving block 7. Finally, the three locking blocks 9 will be retracted into the cavity 4. At this time, the operator can remove the round shaft 1 from inside the entire steel layer 2 and put the new steel layer 2 on the outer surface of the round shaft 1.

[0040] The operator then rotates the threaded rod 6 again, causing the three locking blocks 9 to contact the end face of the new steel layer 2. The operator then starts the drive motor 17. As the drive motor 17 runs, the rotating shaft 18 and the driving rod 19 begin to rotate. At this time, the other end of the driving rod 19 drives the driven rod 20, causing the driven rod 20 to start rotating. Simultaneously, the other end of the driven rod 20 drives the sleeve bolt 21 during rotation, causing the sleeve bolt 21 and the movable plate 22 to move towards the steel layer 2. Eventually, the movable plate 22 contacts the steel layer 2, at which point the entire steel layer 2 is confined between the movable plate 22 and the locking blocks 9, thus ensuring that the entire steel layer 2 does not move left or right.
