[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] Example 1

[0024] like Figures 1-5As shown, this utility model provides a technical solution: a coating roller assembly with a cutting mechanism, including a frame 1. Two sets of symmetrically distributed support plates 2 are fixedly connected to the top of the frame 1. Three staggered roller shafts 3 are rotatably connected to the inner side of the support plates 2. Transmission wheels 4 are fixedly connected to the outer side of each of the three roller shafts 3. A motor 5 is fixedly connected to the outer side of each transmission wheel 4. A cutting mechanism 6 for automatically cutting the fabric is provided on the top of the frame 1. An adjustment mechanism 7 for adjusting the cutting range of the cutting mechanism 6 is also provided on the top of the frame 1. One end of each of the three roller shafts 3 is rotatably connected to the inner side of the support plate 2 via three bearing seats, and the other end of each of the three roller shafts 3 passes through another support plate 2 and is fixedly connected to the three transmission wheels 4. All three transmission wheels 4 are connected to the inner side of the support plates 2 via three bearing seats. The transmission belt connects the three transmission wheels 4, one of which is fixedly connected to the output shaft of the motor 5. The motor 5 is fixedly connected to the outside of the support plate 2. The adjustment mechanism 7 includes a drive wheel 71 fixedly connected to the output shaft of the motor 5 and a bracket 72 fixedly connected to the outside of another set of support plates 2. A driven wheel 73 is externally connected to the drive wheel 71. A drive gear 74 is fixedly connected to the outside of the driven wheel 73. A first driven gear 75 meshes with the outside of the drive gear 74. A protruding rod 76 is fixedly connected to the outside of the first driven gear 75. A sliding rod 77 is rotatably connected to the inside of the first driven gear 75. A limiting plate 78 is fixedly connected to the outside of the sliding rod 77. A fixing rod 79 is slidably connected to the outside of the limiting plate 78. A second... The driven gear 710 and slide rod 77 have two equally spaced insertion holes 711. A pin 712 is inserted into the inner side of each insertion hole 711, and a fixing bracket 713 is inserted into the top of the pin 712. The driving gear 71 is located on the outer side of the transmission wheel 4. A rotating shaft is fixedly connected to the inner side of the driven gear 73. The driving gear 74 is fixedly connected to the outer end of the rotating shaft. The end of the rotating shaft away from the driving gear 74 is rotatably connected to the outer side of the support plate 2 via a bearing seat. The first driven gear 75 and the second driven gear 710 are equally spaced, and both are rotatably connected to the outside of the slide rod 77 via bearing seats. The dimensions of the first driven gear 75 are compatible with those of the driving gear 74, and the dimensions and teeth of the second driven gear 710 are compatible with those of the driving gear 74. The number of teeth is smaller than the first driven gear 75. There are two protrusions 76, which are fixedly connected to the outside of the first driven gear 75 and the second driven gear 710 respectively. Both protrusions 76 pass through the slide bar 77. The end of the slide bar 77 away from the limiting plate 78 passes through the bracket 72 and is fixedly connected to a handle. Both ends of the fixing rod 79 are fixedly connected to the inside of the bracket 72. The distance between the two insertion holes 711 is the same as the distance between the first driven gear 75 and the second driven gear 710. The size of the two insertion holes 711 is adapted to the pin 712. The fixing bracket 713 is fixedly connected to the top of the bracket 72. The fixing bracket 713 has a through hole adapted to the size of the pin 712. The pin 712 passes through the through hole and is inserted into the insertion hole 711.

[0025] With the above technical solution, during use, the user can drive the transmission wheel 4 to rotate via the motor 5. The rotation of the transmission wheel 4 drives the roller 3 to rotate, which in turn conveys the fabric. Simultaneously, the drive wheel 71 also rotates via the motor 5 and transmission wheel 4. The drive wheel 71, through a transmission belt, drives the driven wheel 73 to rotate. The driven wheel 73, in turn, drives the drive gear 74, the first driven gear 75, and the cam 76 to rotate. The cam 76, after rotating, cuts the fabric in conjunction with the cutting mechanism 6. When the cutting length needs adjustment, the user can remove the pin 712 from the insertion hole 711 on the slide bar 77. The user can then slide the slide bar 77 to move the second driven gear 710 to engage with the drive gear 74. The gear 74 is engaged, and the second driven gear 710 meshes with the driving gear 74. Then, the pin 712 can be inserted into the insertion hole 711 on the slide rod 77 after passing through the through hole on the fixing frame 713 again. At this time, the position of the slide rod 77 can be fixed. Since the second driven gear 710 is smaller, the rotation speed of the second driven gear 710 will be faster under the action of the driving gear 74, thereby driving the rotation speed of the cam 76 to increase. This makes the frequency of the cam 76 driving the slide plate 63 to move higher, thereby increasing the cutting frequency of the cutting blade 64 on the fabric, reducing the length of the cut fabric, and thus achieving the effect of adjusting the length of the cut fabric, thereby greatly improving practicality and ease of use.

[0026] Example 2

[0027] like Figures 1-5As shown, this utility model provides a technical solution: a coating roller assembly with a cutting mechanism, including a frame 1. Two sets of symmetrically distributed support plates 2 are fixedly connected to the top of the frame 1. Three staggered roller shafts 3 are rotatably connected to the inner side of the support plates 2. Transmission wheels 4 are fixedly connected to the outer side of each of the three roller shafts 3. A motor 5 is fixedly connected to the outer side of each transmission wheel 4. A cutting mechanism 6 for automatically cutting the fabric is provided on the top of the frame 1. An adjustment mechanism 7 for adjusting the cutting range of the cutting mechanism 6 is also provided on the top of the frame 1. The cutting mechanism 6 includes rectangular grooves 61 formed on the two right-side support plates 2. A limiting rod 62 is fixedly connected to the inner side of the rectangular groove 61, and the outer side of the limiting rod 62 slides... A sliding plate 63 is connected, and a cutting blade 64 is fixedly connected to the bottom of the sliding plate 63. A spring 65 is fixedly connected to the bottom of the sliding plate 63. A sliding groove 66 is opened on the top of the end of the sliding plate 63 near the bracket 72. Two rectangular grooves 61 have the same size and are positioned correspondingly. Limiting rods 62 are fixedly connected to the inner side of each of the two rectangular grooves 61. Both limiting rods 62 are slidably connected to the sliding plate 63. There are two springs 65. One end of each spring 65 is fixedly connected to the bottom of the sliding plate 63, and the other end of each spring 65 is fixedly connected to the inner side of the two rectangular grooves 61. The size of the sliding groove 66 is adapted to the protrusion 76. The length of the cutting blade 64 is the same as the length of the roller 3.

[0028] With the above technical solution, during use, the user can drive the driven wheel 73, the driving gear 74, the first driven gear 75, and the convex rod 76 to rotate via the motor 5. When the convex rod 76 rotates to a certain position, it will contact the sliding groove 66 on the slide plate 63, and drive the slide plate 63 to move through the limit rod 62. While the slide plate 63 moves and compresses the spring 65, it can also drive the cutting blade 64 to move. When the cutting blade 64 moves to a certain position, it can cut the fabric. At the same time, when the convex rod 76 moves to a certain position, it will separate from the sliding groove 66 on the slide plate 63. At this time, the slide plate 63 will return to its original position under the influence of the spring 65. Then, the slide plate 63 will drive the cutting blade 64 to return to its original position. Afterwards, the convex rod 76 will rotate to the position of the sliding groove 66 again and drive the slide plate 63 to move again. Through the continuous movement of the convex rod 76 and the slide plate 63, the fabric can be continuously cut, thereby achieving the effect of automatic cutting, thus improving practicality and production efficiency.

[0029] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
