Description

Technical Field

[0001] This utility model relates to the field of printing equipment, and more specifically, to a printing machine roller assembly. Background Technology

[0002] Roller assembly is a structure widely used in textile-related equipment. By coordinating multiple different rollers, it can achieve various functions including combing, opening, heating, guiding, and correction. Printing machines, as common fabric processing equipment, are also usually equipped with roller assembly structures.

[0003] In some roller sets, there are two rollers with a small gap between them. One roller applies pressure to the fabric to ensure that the fabric can stick tightly to the surface of the other roller. However, when passing one end of the fabric between the two rollers, the fabric is difficult to pass through because the distance between the two rollers is too small. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a printing machine roller assembly.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a printing machine roller assembly, including a support, on which a pressure roller and a guide roller are rotatably connected. A clamping plate is slidably connected to the side wall of the guide roller. The clamping plate slides along the radial direction of the guide roller. When the clamping plate is located at one end of the sliding trajectory away from the axis of the guide roller, the distance between the clamping plate and the guide roller is greater than the distance between the pressure roller and the guide roller. When the clamping plate is located at one end of the sliding trajectory close to the axis of the guide roller, one side of the clamping plate forms a cylindrical surface with the side wall of the guide roller.

[0006] The present invention is further configured such that both sides of the clamping plate are formed with arc surfaces.

[0007] The present invention is further configured such that: a connecting plate is fixedly connected to both sides of the clamping plate, a limiting plate is fixedly connected to the end of the connecting plate away from the clamping plate, a limiting groove is provided on the guide roller along the axis of the guide roller, and the limiting plate is slidably connected in the limiting groove.

[0008] The present invention is further configured such that: an elastic element is provided in the limiting groove, the two ends of the elastic element abut against the side wall of the limiting groove and the limiting plate, and the elastic element is located between the limiting plate and the clamping plate.

[0009] The present invention is further configured such that: a plurality of protruding ridges are fixedly connected to the side wall of the connecting plate.

[0010] The present invention is further configured such that the length of the limiting plate is the same as the length of the guide roller.

[0011] The present invention is further configured such that: a plurality of grooves are provided on both ends of the guide roller, and the grooves are arranged in a circumferential array around the axis of the guide roller.

[0012] In summary, this utility model has the following beneficial effects: the clamping plate and guide roller clamp the fabric, the groove provides two force application points for the rotating guide roller, and by rotating the guide roller, the fabric passes between the guide roller and the pressure roller, saving the time of adjusting the relative position of the pressure roller and the guide roller. Then, the clamping plate is slid to release the fixation of the end of the fabric, and finally the clamping plate and the guide roller re-form a cylindrical surface, ensuring the surface integrity of the guide roller. At the same time, both sides of the clamping plate that contact the fabric are arc surfaces, avoiding damage to the fabric. Attached Figure Description

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Example: A printing machine roller assembly, such as Figure 1 , Figure 2 , Figure 3 As shown, the device includes a support 1, on which a pressure roller 2 and a guide roller 3 are rotatably connected. A clamping plate 4 is slidably connected to the side wall of the guide roller 3. The clamping plate 4 slides along the radial direction of the guide roller 3. When the clamping plate 4 is located at one end of the sliding track away from the axis of the guide roller 3, the distance between the clamping plate 4 and the guide roller 3 is greater than the distance between the pressure roller 2 and the guide roller 3. When the clamping plate 4 is located at one end of the sliding track close to the axis of the guide roller 3, one side of the clamping plate 4 forms a cylindrical surface with the side wall of the guide roller 3, and both sides of the clamping plate 4 form arc surfaces. Several grooves 10 are provided on both ends of the guide roller 3, and the grooves 10 are arranged in a circumferential array around the axis of the guide roller 3.

[0019] Specifically, bracket 1 is located on both sides of pressure roller 2 and guide roller 3, with pressure roller 2 located above guide roller 3. When the fabric needs to pass between guide roller 3 and pressure roller 2, clamping plate 4 is slid away from the axis of guide roller 3, allowing one end of the fabric to pass between clamping plate 4 and guide roller 3. Then, clamping plate 4 is slid to clamp the fabric between clamping plate 4 and guide roller 3. Groove 10 provides two force application points for rotating guide roller 3. By rotating guide roller 3, the fabric passes between guide roller 3 and pressure roller 2, saving time in adjusting the relative positions of pressure roller 2 and guide roller 3. Then, clamping plate 4 is slid to release the fixation of the fabric end. Finally, clamping plate 4 and guide roller 3 re-form a cylindrical surface, ensuring the surface integrity of guide roller 3. At the same time, both sides of clamping plate 4 that contact the fabric are arc surfaces, avoiding damage to the fabric.

[0020] like Figure 1 , Figure 2 , Figure 3 As shown, connecting plates 5 are fixedly connected to both sides of the clamping plate 4. A limiting plate 6 is fixedly connected to the end of the connecting plate 5 away from the clamping plate 4. A limiting groove 7 is opened on the guide roller 3, which runs through the guide roller 3 along the axis of the guide roller 3. The limiting plate 6 is slidably connected in the limiting groove 7. An elastic element 8 is provided in the limiting groove 7. The two ends of the elastic element 8 abut against the side wall of the limiting groove 7 and the limiting plate 6. The elastic element 8 is located between the limiting plate 6 and the clamping plate 4. Several protruding ridges 9 are fixedly connected to the side wall of the connecting plate 5. The length of the limiting plate 6 is the same as the length of the guide roller 3.

[0021] Specifically, the connecting plate 5 is embedded in the end face of the guide roller 3. The connecting plate 5 fixes the distance between the limiting plate 6 and the clamping plate 4. When the limiting plate 6 cannot continue to slide because it is in contact with the side wall of the limiting groove 7, the sliding of the clamping plate 4 is also restricted to prevent the clamping plate 4 from falling off the guide roller 3. In this embodiment, the elastic element 8 is specifically a rubber block. When the clamping plate 4 slides away from the axis of the guide roller 3, the elastic element 8 undergoes compression deformation. The elastic force of the elastic block makes the clamping plate 4 tend to approach the axis of the guide roller 3, preventing the clamping plate 4 from contacting the pressure roller 2 and causing damage to the connecting plate 5 or the clamping plate 4. The protruding ribs 9 are linearly arrayed on the outer side wall of the connecting plate 5, which makes it easy for the operator to slide the clamping plate 4 and the limiting plate 6 through the connecting plate 5. At the same time, the limiting plate 6 passes through the guide roller 3 to ensure that when force is applied from the same end of the limiting plate 6 and the clamping plate 4, the other end of the two can also move synchronously.

[0022] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
