A printing press dryer that is easy to assemble and disassemble

Abstract

This utility model relates to the field of drying technology, specifically a printing press dryer that is easy to assemble and disassemble. It includes a housing, a fan at the top of the housing, a heater inside the housing, and a connecting frame at the top of the housing. The connecting frame is L-shaped and fixedly connected to a fixing plate, with a fixing cylinder fixedly inserted into the connecting frame. This easy-to-assemble printing press dryer allows for easy installation by rotating a knob, which drives a screw to rotate. Since the screw is screwed into the inner cavity of the fixing cylinder, when the screw rotates, the clamping plate slides backward in a straight line under the limiting action of the connecting groove and the connecting block. This allows the fixing plate and the clamping plate to cooperate in clamping and fixing the edge of the printing press, thus achieving the installation of the device. It is simple to operate and convenient to use, solving the problem that existing printing press dryers are inconvenient to install in actual use, requiring complex and cumbersome structures to install the dryer on the printing press.

Description

Technical Field

[0001] This utility model relates to the field of drying technology, specifically a printing press dryer that is easy to assemble and disassemble. Background Technology

[0002] The printing press unit is the core component of a printing press, a key functional unit that transfers graphic information from the printing plate to the substrate during the printing process. During printing, the inking system evenly delivers ink to the image areas of the printing plate on the plate cylinder, while the dampening system evenly coats the non-image areas of the plate with dampening fluid, making the image areas oleophilic and water-repellent, and the non-image areas hydrophilic and oleophilic. When the plate cylinder, blanket cylinder, and impression cylinder rotate simultaneously, the image areas on the plate absorb ink, and the non-image areas absorb dampening fluid.

[0003] However, existing printing press dryers are inconvenient to install in actual use, requiring a complex and cumbersome structure to install the dryer on the printing press. To address this issue, a printing press dryer that is easy to assemble and disassemble is provided. Utility Model Content

[0004] The purpose of this utility model is to provide a printing press dryer that is easy to assemble and disassemble, so as to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: a printing press dryer that is easy to assemble and disassemble, including a housing, a fan provided at the top of the housing, a heater provided in the inner cavity of the housing, a connecting frame provided at the top of the housing, the connecting frame being "L"-shaped and fixedly connected to a fixing plate, a fixing cylinder fixedly inserted into the connecting frame, a screw threaded into the inner cavity of the fixing cylinder, a clamping plate rotatably connected to the rear end of the screw through a bearing, and a knob fixedly connected to the front end of the screw.

[0005] Preferably, the inner cavity of the connecting frame has a connecting groove at the top, and a connecting block is slidably embedded in the inner cavity of the connecting groove. The bottom end of the connecting block is fixedly connected to the top end of the clamping plate. The inner cavity of the connecting groove and the outer wall of the connecting block are adapted to each other and are both dovetail-shaped.

[0006] Preferably, a fixing block is provided on one side of the outer wall of the housing, and fixing holes are respectively provided on the front and rear sides of the fixing block. A frame is provided on the other side of the outer wall of the housing, and a sliding assembly is provided in the inner cavity of the frame. Two sliding plates are provided on the sliding assembly, and a fixing rod is provided on the side of the two sliding plates that are close to each other.

[0007] Preferably, the outer wall of the fixing rod is adapted to fit the inner cavity of the fixing hole.

[0008] Preferably, the sliding assembly includes a lead screw, a handle, a slider, and a limiting assembly. One end of the lead screw is rotatably connected to the rear side of the inner cavity of the frame via a bearing, and the other end of the lead screw extends to the front end of the frame and is fixedly connected to the handle. The two sliders are respectively screwed to the front and rear sides of the outer wall of the lead screw and are respectively fixedly connected to the two slide plates. The limiting assembly is disposed in the inner cavity of the frame and is fixedly connected to the two sliders.

[0009] Preferably, the threads on the front and rear sides of the outer wall of the lead screw are arranged opposite to each other.

[0010] Preferably, the limiting component includes a limiting groove and limiting blocks. The limiting groove is formed in the inner cavity of the frame. The two limiting blocks are slidably embedded in the inner cavity of the limiting groove and are respectively fixedly connected to two sliders. The inner cavity of the limiting groove and the outer wall of the limiting block are adapted to each other and are both in the shape of a "T".

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] By rotating the knob, the screw is driven to rotate. Since the screw is screwed into the inner cavity of the fixed cylinder, when the screw rotates, the clamping plate can slide backward in a straight line under the limiting action of the connecting groove and the connecting block. This allows the fixed plate and the clamping plate to cooperate to clamp and fix the edge of the printing press, thus realizing the installation of the device. The operation is simple and convenient. It solves the problem that the existing printing press dryer is inconvenient to install in actual use and requires a complex and cumbersome structure to install the dryer on the printing press.

[0013] Rotating the handle causes the lead screw to rotate, which in turn generates a relative thread rotational force on the opposing threads on the front and rear sides of the lead screw's outer wall. This causes the two sliders to slide simultaneously towards the center of the machine frame's inner cavity under the limiting action of the limiting groove and the limiting block. The two sliding plates then drive the two fixed rods to slide simultaneously towards the center of the machine frame's inner cavity, allowing the two fixed rods to insert into the inner cavity of the fixing holes on another machine housing. Under the combined action of the fixed rods and fixing holes, the splicing between adjacent machine housings can be achieved. This allows for easy adjustment of the number of devices according to the width of the printing press, improving the flexibility of the device during use. Attached Figure Description

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 5 This utility model provides a technical solution: a printing press dryer that is easy to assemble and disassemble, including a housing 1, a fan 2 installed at the top of the housing 1, a heater 11 installed in the inner cavity of the housing 1, a connecting frame 3 installed at the top of the housing 1, the connecting frame 3 being "L"-shaped and fixedly connected to a fixing plate 4, a fixing cylinder 5 fixedly inserted into the connecting frame 3, a screw 6 screwed into the inner cavity of the fixing cylinder 5, a clamping plate 8 rotatably connected to the rear end of the screw 6 via a bearing, and a knob 7 fixedly connected to the front end of the screw 6. By rotating the knob 7, the dryer can be adjusted to operate the dryer. Knob 7 drives screw 6 to rotate. Since screw 6 is screwed into the inner cavity of fixed cylinder 5, when screw 6 rotates, clamping plate 8 can slide backward in a straight line under the limiting action of connecting groove 9 and connecting block 10, so that fixed plate 4 and clamping plate 8 cooperate to clamp and fix the edge of printing machine, thereby realizing the installation of the device. It is simple to operate and convenient to use, solving the problem that the existing printing machine dryer is inconvenient to install in actual use and requires a complex and cumbersome structure to install the dryer on the printing machine.

[0022] In this embodiment, a connecting groove 9 is provided at the top of the inner cavity of the connecting frame 3. A connecting block 10 is slidably embedded in the inner cavity of the connecting groove 9. The bottom end of the connecting block 10 is fixedly connected to the top end of the clamping plate 8. Under the limiting effect of the connecting groove 9 and the connecting block 10, the clamping plate 8 can be prevented from rotating with the screw 6 when the screw 6 rotates, which improves the flexibility of the device during use. The inner cavity of the connecting groove 9 and the outer wall of the connecting block 10 are adapted to each other and are both dovetail-shaped, which can keep one end of the connecting block 10 embedded in the inner cavity of the connecting groove 9, improving the stability of the connecting assembly during use.

[0023] In this embodiment, a fixing block 12 is provided on one side of the outer wall of the housing 1, and fixing holes 13 are respectively provided on the front and rear sides of the fixing block 12. A frame 14 is provided on the other side of the outer wall of the housing 1. A sliding assembly is provided in the inner cavity of the frame 14. Two sliding plates 15 are provided on the sliding assembly. A fixing rod 16 is provided on the side of the two sliding plates 15 that are close to each other. The sliding assembly drives the two sliding plates 15 and the two fixing rods 16 to slide simultaneously toward the middle of the inner cavity of the frame 14, so that the two fixing rods 16 are respectively inserted into the inner cavity of the fixing hole 13 on the other housing 1. Under the joint action of the fixing rod 16 and the fixing hole 13, the splicing between adjacent housings 1 can be realized. This allows the number of devices to be increased or decreased according to the width of the printing machine, improving the flexibility of the device in use.

[0024] In this embodiment, the outer wall of the fixing rod 16 is adapted to fit the inner cavity of the fixing hole 13, so that the fixing rod 16 can be inserted into the inner cavity of the fixing hole 13.

[0025] In this embodiment, the sliding assembly includes a lead screw 17, a handle 18, sliders 19, and a limiting assembly. One end of the lead screw 17 is rotatably connected to the rear side of the inner cavity of the frame 14 via a bearing, and the other end of the lead screw 17 extends to the front end of the frame 14 and is fixedly connected to the handle 18. Two sliders 19 are respectively screwed to the front and rear sides of the outer wall of the lead screw 17 and are respectively fixedly connected to two sliding plates 15. The limiting assembly is disposed in the inner cavity of the frame 14 and is fixedly connected to the two sliders 19, so that the handle 18 drives the lead screw 17 to rotate, thereby generating threads on the front and rear sides of the outer wall of the lead screw 17. The relative screw rotation force causes the two sliders 19 to slide simultaneously toward the center of the inner cavity of the frame 14 under the limiting action of the limiting groove 20 and the limiting block 21. This causes the two slide plates 15 to drive the two fixing rods 16 to slide simultaneously toward the center of the inner cavity of the frame 14. The two fixing rods 16 are then inserted into the inner cavity of the fixing hole 13 on another housing 1. Under the combined action of the fixing rods 16 and the fixing hole 13, the splicing between adjacent housings 1 can be realized. This allows the number of devices to be increased or decreased according to the width of the printing press, improving the flexibility of the device during use.

[0026] In this embodiment, the threads on the front and rear sides of the outer wall of the lead screw 17 are arranged opposite to each other, so that when the lead screw 17 rotates, the front and rear sides of its outer wall generate relative thread rotation force, so that the two sliders 19 slide relative to each other simultaneously under the limiting action of the limiting groove 20 and the limiting block 21.

[0027] In this embodiment, the limiting component includes a limiting groove 20 and limiting blocks 21. The limiting groove 20 is formed in the inner cavity of the frame 14. Both limiting blocks 21 are slidably embedded in the inner cavity of the limiting groove 20 and are respectively fixedly connected to two sliders 19. Under the joint action of the limiting groove 20 and the limiting blocks 21, the sliders 19 can be prevented from rotating with the lead screw 17 when the lead screw 17 rotates, which improves the stability of the sliding component during use. The inner cavity of the limiting groove 20 and the outer wall of the limiting block 21 are adapted to each other and are both in the shape of "T", which can keep one end of the limiting block 21 embedded in the inner cavity of the limiting groove 20, which improves the stability of the limiting component during use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
