[0001] This utility model relates to the field of printing roller technology, specifically to a printing roller for printing equipment. Background Technology

[0002] Printing equipment consists of machines and tools used to produce various printed materials, widely used in publishing, packaging, advertising, and other industries. Based on different printing technologies and requirements, printing equipment can be categorized into offset printing presses, digital printing presses, flexographic printing presses, screen printing presses, and rotary printing presses. Printing rollers are crucial components on printing presses used to transfer ink and paper. They are typically made of metal materials (such as aluminum or steel) and sometimes covered with a layer of rubber to provide better ink gripping and transfer capabilities. The main types of printing rollers include inking rollers, printing rollers, and pressure rollers.

[0003] Existing printing rollers can only print one fixed pattern because the printing shell and the printing roller are integrated and cannot be disassembled. This limits the application range of the printing roller. If the printing shell is damaged, the entire printing roller needs to be replaced, resulting in a waste of materials and costs. Utility Model Content

[0004] The purpose of this utility model is to provide a printing roller for printing equipment, which solves the problem that existing printing rollers can only print one fixed pattern because the outer printing shell and the printing roller are integrated and cannot be replaced. The application range of the printing roller is fixed, and if the printing shell is damaged, the printing roller needs to be replaced, resulting in waste of materials and costs.

[0005] This utility model solves the above-mentioned technical problems through the following technical solution: This utility model includes:

[0006] A first roller body, with a second roller body at one end of the first roller body. Both the first roller body and the second roller body have two horizontal grooves on their outer sides. The four horizontal grooves have multiple equally spaced slots inside, and magnetic blocks are fixed inside the multiple slots.

[0007] A printing roller shell, wherein annular grooves are provided on both sides of the printing roller shell, and the printing roller shell is disposed outside the first roller body and the second roller body;

[0008] Two mounting assemblies are respectively disposed on the outside of the first roller body and the second roller body. The mounting assemblies are used for quick replacement of the printing roller shell. Each mounting assembly includes a replacement component, which includes an annular positioning block. Two double sliding plates are fixed on the inner side of the annular positioning block. The annular positioning block has two mounting slots and two connecting slots that are respectively connected to the two mounting slots. An inner groove is formed on the outside of the annular positioning block. Magnetic head clamps slide inside the two mounting slots. A central groove inclined plate is fixed on the outside of the two magnetic head clamps. A drive bar passes through the inside of the two central groove inclined plates. The two drive bars slide inside the two connecting slots respectively. One end of each drive bar extends into the inside of the inner groove. A U-shaped drive head is fixed to one end of each drive bar.

[0009] Preferably, a fixing plate is fixed to the inner side of each of the two drive bars, and an assist spring is fixed to the outer side of each of the two fixing plates.

[0010] Preferably, the mounting assembly further includes a telescopic component, which is disposed at one end of the second roller body and is used to change the distance and splicing length between the first roller body and the second roller body.

[0011] Preferably, one end of the first roller body is provided with a pull-out groove, and the telescopic component includes a telescopic rod fixed to one end of the second roller body, an elastic retaining ball fixed inside the pull-out groove, and a connecting piece fixed to one end of the first roller body.

[0013] Preferably, the first roller body and the second roller body are connected by a telescopic rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] By pinching the two U-shaped drive heads in the annular positioning block, a portion of the two drive bars is pulled out of the connecting groove. The drive bars drive the fixing plate to squeeze the assist spring and push the inclined plate of the central groove outwards into the mounting groove, thereby causing the magnetic head clamping plate to slide out of the corresponding slot and release the limitation of the annular positioning block. The annular positioning block can be pulled out along the transverse groove to remove the printing roller shell and replace it with a new one. The new printing roller shell is limited by the two annular positioning blocks. The annular positioning blocks will be limited by the magnetic head clamping plate and the slot. For printing roller shells of different sizes, the distance between the two annular positioning blocks can be changed by clamping the magnetic head clamping plate in the slot at different positions to complete the fixation, so as to realize the installation and fixation of printing roller shells of various sizes, and more than one printing roller shell can be installed and used within the allowable size.

[0023] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0024] This embodiment provides a technical solution: a printing roller for printing equipment, such as... Figure 1-5 As shown, it includes a first roller body 1, a printing roller shell 7, and two mounting components 6. The number of mounting components 6 can be freely set according to the number of printing roller shells 7 set on the first roller body 1 and the second roller body 2 later. The second roller body 2 is set at one end of the first roller body 1. The exterior of the first roller body 1 and the second roller body 2 are provided with two equally spaced transverse grooves 3. The interior of the four transverse grooves 3 is provided with multiple equally spaced slots 4. The interior of the multiple slots 4 is fixed with magnetic blocks 5. The printing roller shell 7 is set on the exterior of the first roller body 1 and the second roller body 2. The two sides of the printing roller shell 7 are provided with annular grooves 8. One end of the second roller body 2 is fixed with an open annular abutment shell 10.

[0025] Two mounting components 6 are respectively disposed on the outside of the first roller body 1 and the second roller body 2. The mounting components 6 are used to quickly replace the printing roller shell 7. The mounting components 6 include a replacement part, which includes an annular positioning block 61. The annular positioning block 61 is divided into two parts: an annular plate and annular positioning plates installed on both sides of the annular plate. The size of the annular positioning plate is adapted to the annular groove 8. Two double sliding plates 62 are fixed on the inner side of the annular positioning block 61. The double sliding plate 62 is composed of two plates. The size of the plates is adapted to the size of the transverse groove 3, and the space between the two plates is just enough to pass through the magnetic head clamping plate 66, that is, the magnetic head clamping plate 66 slides on the inner side of the double sliding plate 62. The interior of the annular positioning block 61 has two mounting grooves 63 and two connecting grooves 64 that are respectively connected to the two mounting grooves 63. The exterior of the annular positioning block 61 has an inner groove 65. Inside each mounting slot 63, a magnetic head clamp 66 slides. The magnetic pole of the magnetic head clamp 66 is the "N pole", and the magnetic pole of the magnetic block 5 is the "S pole". The two attract each other and can fix the magnetic head clamp 66 in the slot 4. A central slot inclined plate 67 is fixed to the outside of each of the two magnetic head clamps 66. A drive bar 68 passes through the inside of each of the two central slot inclined plates 67. The two drive bars 68 slide inside the two connecting slots 64 respectively. One end of each of the two drive bars 68 extends into the inside of the inner slot 65. A U-shaped drive head 69 is fixed to one end of each of the two drive bars 68. A fixing piece 610 is fixed to the inside of each of the two drive bars 68. An assist spring 611 is fixed to the outside of each of the two fixing pieces 610. When the assist spring 611 is at its original length, the distance between the two U-shaped drive heads 69 is the farthest. At this time, the central slot inclined plate 67 is completely in the mounting slot 63.

[0026] The mounting assembly 6 also includes a telescopic component, which is located at one end of the second roller body 2. The telescopic component is used to change the distance and splicing length between the first roller body 1 and the second roller body 2, and is suitable for installation on printing roller shells 7 of various lengths. One end of the first roller body 1 is provided with a pull-out groove 9. The telescopic component includes a telescopic rod 612 fixed to one end of the second roller body 2, an elastic retaining ball 613 fixed inside the pull-out groove 9, and a connecting piece 614 fixed to one end of the first roller body 1. The telescopic rod 612 is slidably connected in the pull-out groove 9. The first roller body 1 and the second roller body 2 are connected by the telescopic rod 612. The telescopic rod 612 has multiple screw holes 615 and multiple alignment holes 616 on its outside. The size of the alignment holes 616 is adapted to the size of the elastic retaining ball 613. The connecting piece 614 is internally threaded with a screw 617. The screw holes 615 and the screw 617 are adapted to each other.

[0027] When replacing the printing roller shell 7, simply pinch the two U-shaped drive heads 69 in the annular positioning block 61. This will cause the two U-shaped drive heads 69 to pull a portion of the two drive bars 68 out of the connecting groove 64. The drive bars 68 will then cause the fixing plate 610 to compress the assist spring 611. As the drive bars 68 move along the path of the connecting groove 64, they will push the central groove inclined plate 67 out of the mounting groove 63. The central groove inclined plate 67 will then cause the magnetic head clamping plate 66 connected to it to slide out of the corresponding clamping groove 4, releasing the limit of the annular positioning block 61. The annular positioning block 61 can then be pulled out of the first roller body 1 or the second roller body 2 along the path of the transverse groove 3 to remove the printing roller shell 7. Place one end of the new printing roller shell 7 between the first roller body 1 and the second roller body 2, and pinch it again. The two U-shaped drive heads 69 in the annular positioning block 61 slide between the magnetic head clamping plate 66 and the double slide plate 62, and slide the double slide plate 62 into the corresponding transverse groove 3. After the corresponding indicator sticker on one side of the annular positioning block 61 is removed, the U-shaped drive heads 69 are released. Under the reset of the assist spring 611, the drive bar 68 is pushed to reset. The magnetic block 5 attracts the magnetic head clamping plate 66, causing the magnetic head clamping plate 66 to be inserted into the corresponding slot 4, thereby fixing the position of the annular positioning block 61. The annular groove 8 at one end of the printing roller shell 7 is clamped onto the annular positioning plate on one side of the annular positioning block 61. Using the same method, another annular positioning block 61 is installed outside the first roller body 1 or the second roller body 2, so that the annular plate on one side of the annular positioning block 61 is clamped onto the annular groove 8 on one side of the printing roller shell 7, thus securing the printing roller shell 7.

[0028] For printing roller shells 7 of different sizes, the spacing between the two annular positioning blocks 61 can be changed by inserting the magnetic head clamp 66 in the slot 4 at different positions in the annular positioning block 61, so as to install and fix printing roller shells 7 of various sizes. For smaller printing roller shells 7, more than one printing roller shell 7 can be installed on the first roller body 1 and the second roller body 2 within the allowable size, as long as the number of annular positioning blocks 61 is changed.

[0029] The length between the first roller 1 and the second roller 2 is changed by pulling the telescopic rod 612 out of the pull-out groove 9. When the telescopic rod 612 moves, the screw 617 and the screw hole 615 are aligned by the elastic ball 613 and the alignment hole 616 at different positions. After the length of the first roller 1 and the second roller 2 is adjusted, one end of the screw 617 is screwed into the corresponding screw hole 615 by rotating the screw 617, thereby fixing the length of the first roller 1 and the second roller 2 and increasing the applicability of the first roller 1 and the second roller 2.

[0030] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
