[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please see Figure 1-6 A winding head pressure roller that is easy to install and adjust includes a base 2. The inner wall of the base 2 is slidably connected to a lifting plate 1 via a lifting mechanism. The lifting plate 1 is provided with a mounting seat 5 inside. The outer wall of the mounting seat 5 is provided with a roller body 3 via a snap-fit ​​mechanism. The snap-fit ​​mechanism includes an insertion hole 6 that passes through the outer wall of the mounting seat 5. The outer wall of the roller body 3 is fixedly connected with a plug 7 that matches the insertion hole 6. The inner wall of the mounting seat 5 is rotatably connected to a rotating ring 8. The outer wall of the rotating ring 8 is rotatably connected to multiple connecting rods 9. The other end of each of the multiple connecting rods 9 is rotatably connected to a locking rod 10 that is slidably connected to the mounting seat 5. The outer wall of the plug 7 is provided with multiple first locking holes 11 that match the locking rods 10. The rear end face of the rotating ring 8 is fixedly connected to multiple connecting shafts 12 that extend to the outer wall of the mounting seat 5. The other end of the multiple connecting shafts 12 is fixedly connected to a turntable 13.

[0025] In this embodiment: Rotating the turntable 13 causes the rotating ring 8 to rotate via the connecting shaft 12, which in turn causes multiple locking rods 10 to slide outward synchronously via multiple connecting rods 9, so that the multiple locking rods 10 can simultaneously disengage from multiple first locking holes 11, thereby disengaging the insert block 7 from the insertion hole 6, i.e., removing the roller body 3. Conversely, when installing the roller body 3, inserting the insert block 7 into the insertion hole 6, aligning the locking rod 10 with the first locking hole 11, and rotating the turntable 13 in the opposite direction, which in turn causes the rotating ring 8 to rotate in the opposite direction via the connecting shaft 12, and the rotating ring 8 further causes the multiple locking rods 10 to slide inward synchronously via the connecting rods 9, so that the locking rods 10 are inserted into the first locking holes 11, thereby fixing the insert block 7, i.e., fixing the roller body 3. This utility model installs and removes the roller body 3 by means of a snap-fit ​​connection, which is convenient for installation and removal.

[0026] As a technical optimization of this utility model, the outer wall of the turntable 13 is slidably connected with a pin 14, the outer wall of the pin 14 is fixedly connected with a limit block 15, the outer wall of the pin 14 is sleeved with a spring 16, one end of the spring 16 is fixedly connected to the turntable 13, the other end of the spring 16 is fixedly connected to the limit block 15, and the rear end face of the mounting base 5 is provided with two second locking holes 17 that match the pin 14.

[0027] In this embodiment: Pull the pin 14 outward to disengage it from one of the second locking holes 17 and stretch the spring 16. At this time, the turntable 13 can be rotated. Rotating the turntable 13 causes the locking rod 10 to engage with or disengage from the first locking hole 11. At this time, the pin 14 rotates until it aligns with the other second locking hole 17. Release the pin 14, and under the elastic force of the spring 16, the pin 14 engages with the other second locking hole 17, fixing the turntable 13 and preventing it from rotating accidentally.

[0028] As a technical optimization of this utility model, the lifting mechanism includes a threaded rod 19 rotatably connected inside the base 2, a first bevel gear 20 fixedly connected to the lower end of the threaded rod 19, a rotating shaft 21 passing through and rotatably connected to the lower end of the base 2, and a second bevel gear 22 meshing with the first bevel gear 20 fixedly connected to the outer wall of the rotating shaft 21.

[0029] In this embodiment: rotating the shaft 21 drives the second bevel gear 22 to rotate, which in turn drives the first bevel gear 20 to rotate, and the first bevel gear 20 further drives the threaded rod 19 to rotate, thereby driving the lifting plate 1 to rise or fall, thereby adjusting the height of the roller 3.

[0030] As a technical optimization of this utility model, the outer wall of the mounting base 5 is provided with multiple circumferentially distributed arc grooves 18.

[0031] In this embodiment: by opening multiple arc grooves 18 on the outer wall of the mounting base 5, it is convenient for the connecting shaft 12 to extend to the outside of the mounting base 5.

[0032] As a technical optimization of this utility model, the base 2 has two limiting rods 23 fixedly connected inside, and the lifting plate 1 is slidably connected to the two limiting rods 23.

[0033] In this embodiment, the limiting rod 23 facilitates the limiting of the lifting plate 1, making the up-and-down movement of the lifting plate 1 stable.

[0034] As a technical optimization of this utility model, the insert 7 is rectangular.

[0035] In this embodiment, the insertion block 7 is set as a rectangle to prevent axial rotation of the insertion block 7.

[0036] As a technical optimization of this utility model, a base plate 4 is fixedly connected to the lower end face of the base 2, and multiple mounting holes are opened on the outer wall of the base plate 4.

[0037] In this embodiment, mounting holes are made on the outer wall of the base plate 4 to facilitate fixing the base plate 4.

[0038] The working principle and usage process of this utility model are as follows: When disassembling the roller body 3, first pull the pin 14 outward to disengage it from one of the second locking holes 17 and stretch the spring 16. At this time, the turntable 13 can be rotated. Then, the turntable 13 rotates, and the turntable 13 drives the rotating ring 8 to rotate through the connecting shaft 12. In turn, multiple connecting rods 9 drive multiple locking rods 10 to slide outward synchronously, so that multiple locking rods 10 disengage synchronously from multiple first locking holes 11. At this time, the pin 14 rotates until it aligns with another second locking hole 17. Release the pin 14, and the pin 14, under the elastic force of the spring 16, will lock into another second locking hole 17. In the locking hole 17, the turntable 13 is fixed to prevent it from rotating accidentally. At this time, the insert 7 can be dislodged from the insertion hole 6, that is, the roller body 3 can be removed. Conversely, when installing the roller body 3, the insert 7 is inserted into the insertion hole 6, so that the locking rod 10 is aligned with the first locking hole 11. The turntable 13 is rotated in the opposite direction, which in turn drives the rotating ring 8 to rotate in the opposite direction through the connecting shaft 12. The rotating ring 8 further drives multiple locking rods 10 to slide inward synchronously through the connecting rod 9, so that the locking rods 10 are inserted into the first locking hole 11, thereby fixing the insert 7, that is, fixing the roller body 3. This utility model installs and removes the roller body 3 by means of locking, which is convenient for installation and removal.
