Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of printing machines, in particular to a clamping mechanism for printing a bottle. Background Art
[0002] Screen printing refers to the method of using a screen perforated plate and printing material to obtain a pattern by scraping, which is referred to as screen printing. The pattern accuracy of screen printing is lower than that of photochemical method, but the process is simple, the production efficiency is high, the cost is low, and it is suitable for mass production.
[0003] In addition to being widely used in flat printing, screen printing can also be used for more regular curved surface printing, mainly referring to the surface printing of bottles. Since the surface of the bottle is a curved surface, it is usually necessary to use a clamping device to support the bottle during printing, and stick the bottle under the printing plate. The bottle then rotates while moving through the printing plate, so that different parts of the bottle contact different parts of the printing plate in turn, and then complete the printing operation. Therefore, in this process, the moving speed of the printing plate needs to be consistent with the linear speed of the outer wall of the bottle. The more consistent the speed, the higher the quality of the printed product.
[0004] The common bottle clamping method is to press the bottle onto the printing plate, and then the printing plate drives the bottle to rotate during the movement. Although this can maintain the consistency of the speed of the two to a certain extent, the friction between the two is not large because the bottle is mostly made of plastic or glass and the printing plate is mostly made of stainless steel. The initial contact of the movement may cause a certain relative sliding, and it is also difficult to ensure that the speed of the two is completely consistent. Therefore, a device with better synchronization for bottle screen printing can be designed. Utility Model Content

[0029] Example
[0030] The following is further described in conjunction with specific embodiments. Figure 1 -Attached Figure 6 As shown, the clamping mechanism for the bottle body 32 during printing of the present embodiment includes a bottom plate 11, a lifting device provided on the bottom plate 11 for supporting the bottle body 32, a first driving device for driving the lifting device to rise and fall, and a second driving device 20 for driving the bottle body 32 to rotate around its axis; the lifting device includes a U-shaped support rod 12, an arc-shaped first support plate 13 with an opening facing upward provided at one end of the support rod 12, and an arc-shaped second support plate 14 with an opening facing upward provided at the other end of the support rod 12; the first support plate 13 is used to support the side edge of the bottom of the bottle body 32, and the second support plate 14 is used to support the side edge of the bottle mouth of the bottle body 32. Specifically, when in use, the bottle body 32 is transported by the conveyor belt 31. When the bottle body 32 is transported to the bottom of the printing plate 33 and is located directly above the support rod 12, the first driving device drives the support rod 12, the first supporting plate 13 and the second supporting plate 14 to rise. The first supporting plate 13 supports the bottom of the bottle body 32, and the second supporting plate 14 supports the bottle mouth of the bottle body 32, so that the bottle body 32 contacts the printing plate 33, and then printing can be started. During printing, the printing plate 33 moves under the drive of an external force, and then the friction between the printing plate 33 and the bottle body 32 causes the bottle body 32 to rotate. At this time, the second driving device 20 also synchronously drives the bottle body 32 to rotate, so that the linear speed of the outer wall of the bottle body 32 is substantially consistent with the linear speed of the printing plate 33, so as to ensure the printing quality. The printing operation can be completed during the movement. After the printing is completed, the support rod 12 is lowered, and the bottle body 32 is put back on the conveyor belt 31. In this way, not only can the printing operation be completed quickly, but also the printing quality can be better guaranteed to avoid printing misalignment, smearing and the like.
[0031] In this embodiment, a horizontally arranged first electric push rod 16 is provided at one end of the support rod 12 close to the second support plate 14, and a block 17 is provided at the end of the telescopic rod of the first electric push rod 16, and the block 17 is arranged toward the bottle mouth of the bottle body 32. The block 17 is made of rubber material, and the first electric push rod 16 is rotatably connected to the block 17. A vertically arranged block is provided on the side of the first support plate 13 away from the second support plate 14, and the block abuts against the outer bottom of the bottle body 32. Specifically, after the support rod 12 pulls up the bottle body 32, the first electric push rod 16 pushes the block 17 into the bottle mouth and abuts the bottom of the bottle body 32 against the block, so that the bottle body 32 can be better positioned and higher-precision printing can be achieved.
[0032] The second driving device 20 in this embodiment includes an arc-shaped clamping plate 21 disposed above the second supporting plate 14 and opening downward, a through hole 22 provided on the clamping plate 21, a first roller 23 disposed in the through hole 22, and a power assembly for driving the first roller 23 to rotate; the first roller 23 abuts against the outer wall of the bottle mouth of the bottle body 32; the clamping plate 21 is connected to the fixed object through a fixing rod. The power assembly includes a second roller 24 abutting against the outer wall of the first roller 23, a third roller 25 abutting against the lower side of the printing plate 33, a first belt pulley 27 disposed on the second roller 24, a second belt pulley 28 disposed on the third roller 25, and a transmission belt 29 for connecting the first belt pulley 27 and the second belt pulley 28; the diameter of the first belt pulley 27 is greater than the diameter of the second belt pulley 28; the first roller 23, the second roller 24, and the third roller 25 are all disposed on the clamping plate 21 through a fixing bar 26. Specifically, when the bottle body 32 is driven to rotate, in addition to the outer wall of the bottle body 32 contacting the printing plate 33 to drive the bottle body 32 to rotate, the printing plate 33 can also drive the third roller 25 to rotate when it moves, and the transmission belt 29 between the third roller 25 and the second roller 24 drives the second roller 24 to rotate, and then the connection between the second roller 24 and the first roller 23 drives the first roller 23 to rotate, and finally the first roller 23 directly drives the bottle body 32 to rotate, so that the movement of the universal printing plate 33 is realized, and the bottle mouth of the bottle body 32 is indirectly driven to rotate, so that the transmission delay is less and no additional power mechanism is required. Among them, the second roller 24 and the third roller 25 are equivalent to the deceleration mechanism (the linear speed of the printing plate 33 when moving is obviously greater than the linear speed at the bottle mouth, so it needs to be decelerated, and other deceleration structures with the same function can also be used). It should be noted that the fixed object refers to a fixed device, such as a structure such as the bottom plate 11.
[0033] In this embodiment, a pair of the second roller 24 and the third roller 25 are provided. The pair of second rollers 24 are both in contact with the first roller 23 ; and a third roller 25 is connected to a second roller 24 .
[0034] The first driving device in this embodiment includes a pair of driving plates 18 respectively disposed at both ends of the support rod 12, and a pair of second electric push rods 19 respectively connected to the pair of driving plates 18 and vertically disposed; the second electric push rods 19 are connected to the bottom plate 11. The first driving device also includes a pair of sleeves respectively disposed vertically at both ends of the support rod 12, and a bracket 110 connected to the sleeves, the bracket 110 is connected to the bottom plate 11, and the sleeves are sleeved on the outer wall of the support rod 12. Specifically, the pair of second electric push rods 19 synchronously push the support rod 12 up and down, and the sleeves can make the movement of the support rod 12 more stable and smooth.
[0035] In summary, the clamping mechanism for printing the bottle body 32 of this embodiment transports the bottle body 32 through the conveyor belt 31 when in use. When the bottle body 32 is transported to the bottom of the printing plate 33 and is located directly above the support rod 12, the first driving device drives the support rod 12, the first support plate 13 and the second support plate 14 to rise. The first support plate 13 supports the bottom of the bottle body 32, and the second support plate 14 supports the bottle mouth of the bottle body 32, so that the bottle body 32 contacts the printing plate 33, and then printing can be started. During printing, the printing plate 33 moves under the drive of an external force, and then The friction between the bottle body 32 and the bottle body 32 causes the bottle body 32 to rotate, and at this time, the second driving device 20 also synchronously drives the bottle body 32 to rotate, so that the linear speed of the outer wall of the bottle body 32 is basically consistent with the linear speed of the movement of the printing plate 33, thereby ensuring the printing quality. The printing operation can be completed during the movement. After the printing is completed, the support rod 12 is lowered and the bottle body 32 is put back on the conveyor belt 31. In this way, not only can the printing operation be completed quickly, but also the printing quality can be better guaranteed to avoid printing misalignment, smearing, etc.
[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
