[0002] After plastic buckets are manufactured, they often need to be printed with specific colors or have glue applied to a fixed position on their surface for attaching labels. During the printing process, the plastic buckets need to be clamped to facilitate the printing coating process on the outer surface of the plastic buckets.
[0003] A search revealed that this utility model relates to the field of printing technology, specifically disclosing a plastic bucket printing device. The device includes a printing component, a fixing component, and an adjusting component. The printing component is installed on one side of the fixing component, which is installed above the adjusting component. The fixing component includes a support plate, a first fixing plate, a second fixing plate, and two sliding units. The two sliding units are symmetrically arranged at both ends of the first fixing plate. Each sliding unit includes an extension block, a connecting plate, a connecting block, and a connecting rod. One end of the connecting plate is slidably connected to a first sliding groove, and both ends of the connecting rod are slidably connected to a second and a third sliding groove, respectively. One end of the connecting block is fixedly connected to the top of the connecting rod, and the other end of the connecting block is slidably connected to a fourth sliding groove. This structural design allows for the fixing of plastic buckets of different sizes without frequent clamp changes, thus saving costs and improving printing efficiency.
[0004] The plastic bucket printing device in the aforementioned patent still has certain shortcomings. During the printing process on the surface of existing plastic buckets, the plastic bucket body is pressed to varying degrees. However, the plastic bucket body is not very rigid, and therefore, it will deform to some extent during the pressing process. This causes the printed pattern on the surface of the bucket body to deform to varying degrees, affecting the overall printing quality and making it inconvenient for users to use the printed bucket. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a plastic bucket printing device that solves the problem that in the process of printing patterns on the surface of plastic buckets, the plastic bucket body is pressed to varying degrees. However, the plastic bucket body is not very rigid, and therefore, certain deformation will occur during the pressing process. As a result, the printed pattern on the surface of the bucket body will be deformed to varying degrees, affecting the overall printing quality and making it inconvenient for users to use the printed bucket.

A top connecting block is connected to the top of the drive connecting plate, and an abutment push plate is fixed to the top of the top connecting block. An inner wall support plate is arranged on the side of each abutment push plate. Three connecting screws are evenly arranged on the side of each inner wall support plate, and the ends of each connecting screw pass through the abutment push plate. A connecting nut is fitted onto the end of each connecting screw.
[0008] Preferred technical solution 1: The printing rotating assembly includes a bottom support platform disposed at the bottom of the supporting disc, with supporting legs evenly arranged around the bottom end of the bottom support platform, a rotating groove formed at the top end of the bottom support platform, an annular limiting groove formed on the inner side wall of the rotating groove, a central through hole formed in the middle of the bottom wall of the rotating groove, a servo motor fixed at the bottom of the bottom support platform, a connecting ring fixed at the bottom end of the supporting disc, and a plurality of limiting contact blocks evenly arranged on the outer side of the connecting ring.

[0015] This design allows the limiting contact block to slide more smoothly in the annular limiting groove, effectively limiting the connection ring.
[0016] Compared with the prior art, the present invention provides a plastic bucket printing device, which has the following beneficial effects:
[0017] This invention features a barrel printing support assembly mounted on a supporting disc. Two inner wall support plates within this assembly are driven by a drive screw via a drive motor. This drive screw, through a connecting plate, drives an abutment plate, causing the inner wall support plates to abut against the inner wall of the plastic barrel. This effectively supports the inner wall of the plastic barrel, allowing for appropriate pressure when printing patterns on the outer surface. This prevents the printed patterns from being affected by barrel deformation, significantly improving the printing quality. Meanwhile, a servo motor in the printing rotation assembly rotates the supporting disc via a rotating connecting column. Simultaneously, the supporting disc rotates the fixed plastic barrel, making it easier for users to print patterns on various support surfaces of the plastic barrel. Attached Figure Description

[0025] Please see Figure 1-4 ,
[0026] Example 1: A plastic bucket printing device includes a support disc 1, a bucket body printing support component 2 is provided on the top of the support disc 1, and a printing rotation component 3 is provided on the bottom of the support disc 1.
[0027] The barrel printing support assembly 2 includes a top drive groove 201 located at the center of the top of the support disc 1. A drive screw 202 is rotatably inserted into the top drive groove 201, with the end of the drive screw 202 rotatably penetrating through the top drive groove 201. A drive motor 203 is located on the outer side of the support disc 1, and the drive shaft of the drive motor 203 is fixedly connected to the end of the drive screw 202. Two drive connecting plates 204 are symmetrically inserted into the top drive groove 201, with the drive screw 202 threaded through the center of each drive connecting plate 204. Two limiting rods 205 are symmetrically arranged inside 201. The limiting rods 205 pass through the side of the driving connecting plate 204. The top of the driving connecting plate 204 is connected to a top connecting block 206. The top of the top connecting block 206 is fixed with an abutting push plate 207. The side of the abutting push plate 207 is provided with an inner wall support plate 208. Three connecting screws 209 are evenly arranged on the side of the inner wall support plate 208. The ends of the connecting screws 209 pass through the abutting push plate 207. The ends of the connecting screws 209 are fitted with connecting nuts 210.
[0028] The printing rotating assembly 3 includes a bottom support platform 301 disposed at the bottom of the support disk 1. Support legs 302 are evenly arranged around the bottom end of the bottom support platform 301. A rotating groove 309 is opened at the top of the bottom support platform 301. An annular limiting groove 303 is opened on the inner side wall of the rotating groove 309. A central through hole 304 is opened in the middle of the bottom wall of the rotating groove 309. A servo motor 305 is fixed at the bottom of the bottom support platform 301. A connecting ring 306 is fixed at the bottom end of the support disk 1. A plurality of limiting contact blocks 307 are evenly arranged on the outer side of the connecting ring 306. The connecting ring 306 is inserted into the rotating groove 309. The limiting contact blocks 307 are slidably inserted into the annular limiting groove 303. A rotating connecting column 308 is fixed in the middle of the bottom end of the support disk 1. The bottom end of the rotating connecting column 308 passes through the central through hole 304 and is fixedly connected to the drive shaft at the top of the servo motor 305.
[0029] Example 2: The difference between this example and Example 1 is that the threads at both ends of the drive screw 202 are in opposite directions, and the drive screw 202 is threaded through to drive the connecting plate 204.
[0030] This allows the drive screw 202 to simultaneously drive the two drive connecting plates 204, through which its threads pass, to move closer to or further away from each other.
[0031] Example 3: The difference between this example and Example 1 is that the bottom side of the drive motor 203 is connected to the support disk 1 through a fixed plate.
[0032] This makes the drive motor 203 more stable when driving the drive screw 202.
[0033] Example 4: The difference between this example and Example 1 is that the end of the limiting contact block 307 is hemispherical, and the limiting contact block 307 is slidably inserted into the annular limiting groove 303.
[0034] This makes the limiting contact block 307 slide more smoothly in the annular limiting groove 303, and fully limits the connecting ring 306.
[0035] In this embodiment, since the plastic bucket body is pressed to varying degrees during the printing process, the plastic bucket body is not very hard, and therefore will deform to a certain extent during the pressing process. As a result, the printed pattern on the surface of the bucket body will be deformed to varying degrees, affecting the overall printing quality and making it inconvenient for users to use the printed bucket body.
[0036] In summary, in practical implementation, when the user needs to print patterns on the surface of the cylindrical plastic bucket, the user can first place the open end of the plastic bucket on the outside of the two inner wall support plates 208. The user can then start the drive motor 203, which can be driven by a battery without external wiring. The drive motor 203 drives the two drive connecting plates 204 to move away from each other through the drive screw 202. This causes the drive connecting plates 204 to drive the two abutting push plates 207 to move away from each other through the top connecting block 206. In turn, the sides of the abutting push plates 207 are connected to the inner wall support plates 208 through the connecting screw 209 to abut against the inner wall of the plastic bucket, so that the inner wall of the plastic bucket is supported by the abutment.
[0037] Furthermore, since the inner wall support plate 208 is fixed by the connecting screw 209 passing through the abutting push plate 207 and the connecting nut 210, the user can replace the inner wall support plate 208 with different curvatures according to the size of the plastic bucket. This makes the inner wall support plate 208 fit the inner wall of the plastic bucket more closely. When the user prints patterns on the outer wall of the plastic bucket, appropriate pressure can be applied, and the pattern printing on the surface of the bucket can be clearer. There will be no problem of pattern deformation due to bucket deformation, making printing more convenient and faster.
[0038] The printing rotating assembly 3, located at the bottom of the supporting disc 1, has a servo motor 305 that drives the supporting disc 1 to rotate via a rotating connecting column 308. The bottom of the supporting disc 1 is inserted into the rotating groove 309 via a connecting ring 306. The side of the connecting ring 306 is inserted into the annular limiting groove 303 via several limiting contact blocks 307. This effectively limits the rotation of the supporting disc 1, ensuring greater stability when the plastic bucket, which is fixed against the top of the supporting disc 1, rotates for printing. This facilitates printing operations on multiple contact areas of the plastic bucket and makes it more convenient for users to print patterns on the bucket body.
