Description

Technical Field

[0001] This utility model relates to the field of printing roller technology, and in particular to a support platform above a printing roller. Background Technology

[0002] The support platform above the printing roller in a ton bag printing machine refers to the platform located above the printing roller to support and fix the printing roller and its related components. This ensures the printing roller remains stable under high-speed rotation and pressure, preventing the printed pattern from shifting or becoming blurry due to shaking. It also fixes the axial position of the printing roller to prevent it from shifting during printing, which would affect printing accuracy. After product cutting, each piece of material needs to be printed with corresponding product information, making it inconvenient to clean the printing roller when necessary.

[0003] A search revealed Chinese Patent Publication No. CN112026341A, which discloses a printing device with a cutting mechanism. The device includes a base, a support column fixed to the top of the base, a printing platform and a cutting platform fixed to the top of the support column, a U-shaped frame fixed to the printing platform with its bottom end fixedly connected to the base, an clearance channel inside the printing platform, a driving printing roller and a driven printing roller rotatably connected to the U-shaped frame, with the driven printing roller embedded within the clearance channel, a printing motor fixed to one side of the U-shaped frame, and the output shaft of the printing motor fixedly connected to the driving printing roller. One end of the printing roller is fixed with a drive gear, and the output shaft of the driven printing roller is fixed with a driven gear. The drive gear and the driven gear are meshed and connected. This printing device with a cutting mechanism can meet the cutting requirements of different lengths. At the same time, the cutting is completed during the printing process, which has a relatively high production efficiency and allows for intuitive knowledge of the output. However, in the existing support platform above the printing roller, when the printing roller rotates at high speed and bears a large pressure, it vibrates and deforms due to insufficient rigidity, resulting in ghosting, blurring and misregistration of the printed pattern. If the support platform is not properly sealed during the processing, it is easy for ink and dust to enter and cause wear. It needs to be disassembled and cleaned regularly, which results in high maintenance costs. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a support platform above the printing roller, which aims to improve the problems in the prior art where insufficient rigidity causes vibration and slight deformation, resulting in ghosting, blurring and misregistration of printed patterns, and if the support platform is not properly sealed during processing, it needs to be disassembled and cleaned regularly, resulting in high maintenance costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a support platform above a printing roller, comprising a worktable, a support mechanism fixedly connected to the top left side of the worktable for supporting and protecting the printing roller, an adjustment mechanism fixedly connected to the bottom right side of the support mechanism for adjusting the spacing between the printing rollers, a conveying mechanism fixedly connected to the top right side of the worktable, a motor fixedly connected to the rear side of the outer wall of the support mechanism, a printing cylinder fixedly connected to the output end of the motor, the support mechanism comprising a support frame fixedly connected to the left side of the outer wall of the worktable, a support platform fixedly connected to the top adjacent side of the top of the support frame, a fixed frame fixedly connected to the top of the outer wall of the support frame, a fumigation hood fixedly connected to the top of the outer wall of the fixed frame, a curtain fixedly connected to the bottom of the outer wall of the fumigation hood, and the curtain fixedly connected to the top of the outer wall of the support platform.

A pushing component is fixedly connected to the bottom rear side of the fixed frame.

[0009] The above technical solution involves starting a hydraulic push rod, driving a gear to rotate and move along a rack, causing a moving block within the fixed frame to slide. The moving block then drives the pad, the compaction cylinder, and the connecting frame. Adjusting the extension and retraction of the hydraulic push rod allows for adjustment of the position and pressure of the compaction cylinder, thereby controlling the material compaction.

[0010] As a further description of the above technical solution:

[0011] The pushing assembly includes a hydraulic push rod, which is fixedly connected to the bottom rear side of the fixed frame. The output end of the hydraulic push rod is rotatably connected to a gear. A rack is fixedly connected to one side of the inner wall of the fixed frame, and the rack meshes with the gear.

[0012] The above technical solution involves installing a hydraulic push rod in the component at the bottom rear of the fixed frame.

[0019] As a further description of the above technical solution:

[0020] A conveying pipe is fixedly connected to the right side of the inner wall of the support frame, and branch pipes are provided around the outer wall of the conveying pipe.

[0021] Through the above technical solution: the conveying pipe is fixed to the right side of the inner wall of the support frame as a fluid transmission channel, and the branch pipes around it are used for diversion, so that the fluid enters from one end and is evenly distributed to different positions.

[0026] The inner wall of the smoking hood is connected to a ventilation pipe, and the smoking hood adopts an inverted funnel-shaped design.

[0027] The above technical solution involves designing the fume hood in an inverted funnel shape to effectively collect smoke and dust in the work area and discharge it through the central vent pipe, ensuring a clean environment.

[0028] This utility model has the following beneficial effects:

[0029] 1. In this utility model, the motor is mounted on the rear side of the support mechanism. After starting, it drives the printing cylinder to rotate to complete the printing.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides: a support platform above a printing roller, including a workbench 1, a support mechanism 2 fixedly connected to the top left side of the workbench 1, the support mechanism 2 being used to support and protect the printing roller, an adjustment mechanism 3 fixedly connected to the bottom right side of the support mechanism 2, the adjustment mechanism 3 being used to adjust the spacing between the printing rollers, a conveying mechanism 4 fixedly connected to the top right side of the workbench 1, a motor 5 fixedly connected to the rear side of the outer wall of the support mechanism 2, a printing cylinder 6 fixedly connected to the output end of the motor 5, the support mechanism 2 including a support frame 201, the support frame 201 fixedly connected to the left side of the outer wall of the workbench 1, a support platform 202 fixedly connected to the top adjacent side of the top of the support frame 201, a fixed frame 203 fixedly connected to the top of the outer wall of the support frame 201, a fumigation hood 205 fixedly connected to the top of the outer wall of the fixed frame 203, a curtain 204 fixedly connected to the bottom of the outer wall of the fumigation hood 205, the curtain 204 fixedly connected to the top of the outer wall of the support platform 202, a conveying pipe 7 fixedly connected to the right side of the inner wall of the support frame 201, and branch pipes 8 opened around the outer wall of the conveying pipe 7;

[0040] Specifically, motor 5 is installed on the rear side of support mechanism 2. After starting, it drives printing cylinder 6 to rotate and complete the printing task. Printing cylinder 6 is stably supported by support mechanism 2. Support frame 201 is arched to ensure structural stability and is fixed on the left side of worktable 1. The top of the support frame 202 supports the core component of printing roller. Fixing frame 203 is installed on top of support frame 201 to fix fumigation hood 205. Curtain 204 is suspended between the bottom of fumigation hood 205 and support frame 202 to form a semi-enclosed space, which prevents the spread of pollutants and reduces external interference. A support platform is provided above printing roller. The platform has a mesh structure with a rotatable top that can be opened and closed for easy cleaning of the printing rollers. The top of the support platform is also equipped with a fume hood 205 and a curtain 204 to prevent the spread of smoke. The conveying pipe 7 fixed on the right side of the inner wall of the support frame 201 can serve as a fluid transmission channel. The branch pipes 8 opened around its outer wall serve as a diversion function. During operation, the fluid enters from one end of the conveying pipe 7 and is evenly distributed to different positions through the branch pipes 8. It can be used for material conveying, conveying clean gas through the branch pipes 8 to remove dust from the equipment, or conveying liquid to treat the surface of materials, thereby meeting different process requirements.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The adjusting mechanism 3 includes a fixed frame 301, which is fixedly connected to the bottom right side of the support mechanism 2. A moving block 302 is slidably connected to the middle of the inner wall of the fixed frame 301. A pad 303 is fixedly connected to the outer wall of the moving block 302 on the side away from it. A rolling cylinder 304 is rotatably connected to the outer wall of the moving block 302 on the side adjacent to it. A connecting frame 305 is rotatably connected to the bottom of the outer wall of the moving block 302. A pushing assembly 306 is fixedly connected to the bottom rear side of the fixed frame 301. The pushing assembly 306 includes a hydraulic push rod 3061, which is fixedly connected to the bottom rear side of the fixed frame 301. A gear 3062 is rotatably connected to the output end of the hydraulic push rod 3061. A rack 3063 is fixedly connected to one side of the inner wall of the fixed frame 301. The rack 3063 meshes with the gear 3062. A scraper 9 is fixedly connected to the right side of the inner wall of the support frame 201. The support frame 201 adopts an arched design.

[0042] Specifically, after the hydraulic push rod 3061 is activated, its output end drives the gear 3062 to rotate. Because the gear 3062 meshes with the rack 3063 on the inner wall of the fixed frame 301, the rotating gear 3062 moves along the rack 3063, thereby driving the moving block 302 inside the fixed frame 301 to slide. When the moving block 302 moves, it drives the pad 303, the compaction cylinder 304, and the connecting frame 305. By adjusting the extension and retraction of the hydraulic push rod 3061, the position and compaction pressure of the compaction cylinder 304 can be changed, thereby realizing the adjustment of the compaction of the material and pushing the assembly 3061. In section 6, the hydraulic push rod 3061 is fixed to the bottom rear side of the fixed frame 301. When the hydraulic push rod 3061 is started, its output end drives the gear 3062 to rotate. Since the gear 3062 meshes with the rack 3063 on one side of the inner wall of the fixed frame 301, the rotating gear 3062 will move along the rack 3063, thereby realizing the position adjustment of related components. At the same time, the scraper 9 fixed on the right side of the inner wall of the arched support frame 201 can scrape and clean the surface of the material when it passes by, ensuring the flatness and cleanliness of the material processing.

[0043] Reference Figure 1 , Figure 2 and Figure 3 The conveying mechanism 4 includes a second connecting frame 401, which is fixedly connected to the top right side of the workbench 1. A conveying plate 402 is fixedly connected to one side of the outer wall of the second connecting frame 401, and a support rod 403 is fixedly connected to the other side of the conveying plate 402. An auxiliary wheel 404 is rotatably connected to the bottom of the outer wall of the support rod 403. A limit component 405 is slidably connected to the top of the outer wall of the second connecting frame 401. The limit component 405 includes a moving rod 4051, which is slidably connected to the top of the outer wall of the second connecting frame 401. Multiple spring plates 4052 are fixedly connected to the right side of the outer wall of the moving rod 4051, and rollers 4053 are rotatably connected to the bottom of the outer wall of the spring plates 4052. A ventilation pipe 10 is connected to the middle of the inner wall of the smoke hood 205. The smoke hood 205 adopts an inverted funnel-shaped design.

[0044] Specifically, the conveying mechanism 4 is responsible for material transfer. The connecting frame 401 is fixed to the top right side of the workbench 1. The conveying plate 402 on it cooperates with the support rod 403 and the auxiliary wheel 404 to assist the material movement. The limiting component 405 at the top of the connecting frame 401 can be adjusted by sliding the moving rod 4051. The spring plate 4052 and the roller 4053 can limit and guide the material. At the same time, the fume hood 205 is shaped like an inverted funnel, which can effectively collect the smoke and dust generated in the working area and discharge them through the ventilation pipe 10 connected in the middle of its inner wall to ensure a clean working environment.

[0045] Working principle: The motor 5 is fixed to the rear side of the support mechanism 2. After starting, it drives the printing cylinder 6 to rotate through the output end to realize the printing function. The printing cylinder 6 is supported by the support mechanism 2 to ensure its stable rotation. The support frame 201 is arched to ensure the structural load-bearing capacity. It is fixed to the left side of the worktable 1. The top of the support frame 202 supports the core component of the printing roller and provides structural support. The fixing frame 203 is installed on the top of the support frame 201 to fix the smoke hood 205. The curtain 204 is suspended between the bottom of the smoke hood 205 and the support frame 202 to form a semi-enclosed space. On the one hand, it prevents the spread of pollutants, and on the other hand, it reduces external interference during the printing process. The fume hood 205 collects exhaust gas simultaneously and discharges it through the ventilation pipe 10. The scraper 9 on the inner wall of the support frame 201 can smooth the surface when the material passes by, ensuring printing quality and material flatness. A support platform is provided above the printing roller. The support platform is a support mesh. The top of the support platform can be rotated to open and close. Workers can stand on the support platform and open the support platform to clean the printing roller. The top of the support platform is also equipped with a fume hood 205 and a curtain 204 to prevent the smoke from spreading outward.

[0046] After the hydraulic push rod 3061 in the push assembly 306 is started, its output end drives the gear 3062 to rotate. Since the gear 3062 meshes with the rack 3063 fixed on one side of the inner wall of the fixed frame 301, the rotating gear 3062 moves along the rack 3063, thereby driving the moving block 302 in the fixed frame 301 to slide in the middle of the inner wall of the fixed frame 301. When the moving block 302 moves, the pad 303 fixed on it, the rotatably connected crushing cylinder 304, and the connecting frame 305 move accordingly, which can adjust the crushing of the material. By adjusting the extension and retraction of the hydraulic push rod 3061, the position and crushing pressure of the crushing cylinder 304 can be changed.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
