[0033] Reference Figure 1 and Figure 2 The utility model provides a locking device according to this embodiment, comprising a base 1, a locking assembly, a locking driver 7, and an adjustment plate 41. The locking assembly is movably connected to the base 1, the fixed end of the locking driver 7 is fixedly connected to the base 1, and the driving end of the locking driver 7 is connected to the locking assembly for driving the locking assembly to reciprocate in a first direction.

[0034] The adjustment plate 41 is located below the base 1 , the upper surface of the adjustment plate 41 is opposite to the lower surface of the base 1 , and the adjustment plate 41 is slidably connected to the locking assembly;

[0035] The locking assembly includes two groups of connecting plates 2, linear bearings 3 and tooling shafts 4. The two groups of connecting plates 2 are respectively provided at both ends of the linear bearings 3. The linear bearings 3 are provided through the base 1 and are slidably connected to the base 1. One end of the tooling shaft 4 is connected to the side of the connecting plate 2 away from the base 1, and the other end of the tooling shaft 4 is connected to the adjustment plate 41. When the locking drive member 7 is in operation, the adjustment plate 41 reciprocates along the first direction.

[0036] The linear bearings 3 are provided in two groups, and the two groups of linear bearings 3 are provided on both sides of the length direction of the base 1;

[0037] The locking assembly also includes a locking seat 5 and a locking rod 6. The locking seat 5 is connected to the base 1. The locking seat 5 and the locking rod 6 are arranged on the same axis. The locking rod 6 is rotatably connected to the adjustment plate 41. The other end of the adjustment plate 41 is slidably connected to the linear bearing 3.

[0038] The locking device of the present application is applied to tooling structures of various bottles that require processes such as rotary printing, hot stamping, and colored paper pasting. First, the product bottles are locked, and then the rotary printing, hot stamping, and other processes are carried out.

[0039] The locking device includes a base 1, on which a locking assembly, a locking drive 7 and an adjustment plate 41 are provided. The locking assembly is movably connected to the base 1, and the base 1 is provided with a mounting groove 11. The locking drive 7 is arranged in the mounting groove 11. The fixed end of the locking drive 7 is fixedly connected to the base 1, and the driving end is connected to the locking assembly for driving the locking assembly to reciprocate along the first direction. In this embodiment, the locking drive 7 is a driving cylinder.

[0040] An adjustment plate 41 is slidably connected to the locking assembly. Specifically, the adjustment plate 41 is located below the base 1, with its upper surface facing the lower surface of the base 1. This design allows the device to adjust the distance between the adjustment plate 41 and the base 1 as needed to accommodate bottles of different lengths. When the locking driver 7 is activated, it drives the locking assembly to reciprocate in the first direction, driving the adjustment plate 41 to move synchronously. Through this movement, the adjustment plate 41 can adjust the distance between itself and the base 1, allowing the device to stably lock bottles of different lengths without having to replace the clamp.

[0041] The locking assembly consists of two groups of connecting plates 2, two groups of linear bearings 3 and a tooling shaft 4. The two groups of connecting plates 2 are respectively arranged at both ends of the linear bearing 3 in the width direction, and the two groups of bearings are respectively located on both sides of the length direction of the base 1. The linear bearing 3 passes through the base 1 and is slidably connected thereto. The connecting plates 2 include a first connecting plate and a second connecting plate. The first connecting plate is arranged above the base 1, and its lower surface is opposite to the upper surface of the base 1. The second connecting plate is arranged below the base 1, and its upper surface is opposite to the lower surface of the base 1. The second connecting plate is connected to the driving end of the locking drive 7. The tooling shaft 4 is slidably connected to the base 1 through the linear bearing 3, and is respectively connected to the first connecting plate, the second connecting plate and the adjustment plate 41. When the locking drive 7 is running, it drives the connecting plates 2, the linear bearings 3 and the tooling shaft 4 to move synchronously. Driven by the tooling shaft 4, the adjustment plate 41 also makes reciprocating motion relative to the base 1, thereby locking the product bottle.

[0042] The locking assembly also includes a locking seat 5 and a locking rod 6. The locking seat 5 is connected to the base 1 and is on the same axis as the locking rod 6. The locking rod 6 is rotatably connected to the adjusting plate 41. This device is a tooling structure used for various bottles that require rotary printing, hot stamping, and colored paper pasting. The device of this application first locks the product bottle and then performs rotary printing, hot stamping, and other processes. The design of the rotatable connection between the locking rod 6 and the adjusting plate 41 is intended to adapt to the needs of the bottle body in process operations such as rotary printing, hot stamping, and colored paper pasting. During these processes, the bottle needs to be rotated, and the locking device not only needs to firmly fix the bottle body, but also must allow the bottle body to rotate freely in the locked state. Therefore, the rotatable connection between the locking rod 6 and the adjusting plate 41 allows the bottle body to still perform rotational movement after being locked, thereby cooperating to complete rotary printing or other related processes.

[0043] The locking device also includes a rotary drive member 8 and a rotary shaft 9. One end of the rotary shaft 9 is connected to the rotary drive member 8, and the other end of the rotary shaft 9 is passed through the base 1 and connected to the locking seat 5. The rotary drive member 8 is used to drive the rotary shaft 9 to rotate.

[0044] The rotary drive member 8 is arranged above the base 1. In this embodiment, the rotary drive member 8 is a servo motor. The rotary shaft 9 is penetrated by the base 1 and is rotatably connected to the base 1. One end of the rotary shaft 9 is connected to the driving end of the rotary drive member 8, and the other end is fixedly connected to the locking seat 5. The rotary drive member 8 drives the rotary shaft 9 to rotate. In the actual working state, after the locking assembly completes the locking work on the product bottle, the rotary drive member 8 starts to run, driving the rotary shaft 9 to rotate, and the rotary shaft 9 drives the locking seat 5 to rotate. At the same time, the locking rod 6 rotates relative to the adjustment plate 41. The locking assembly and the rotating device cooperate to complete the rotary printing or other related processes of the product.

[0045] A supporting member 61 is provided on the side of the locking rod 6 away from the adjustment plate 41, and the supporting member 61 is used to stably support the product;

[0046] The supporting member 61 is conical.

[0047] A conical supporting part 61 is provided on the side of the locking rod 6 close to the product bottle, which is used to cooperate with the bottom of the bottle. When the product bottle is fixed, the locking rod 6 moves toward the product surface under the action of the locking drive cylinder, and the supporting part 61 abuts the product surface. The two work together to achieve the fastening and locking of the product. Since the conical structure has good stability, the bottle body can rely on the support of the supporting part 61 to maintain balance during rotation. Even in the case of high-speed rotation, the supporting part 61 can effectively disperse the pressure through the conical edge to prevent the bottle body from being displaced due to imbalance, thereby successfully completing printing, hot stamping or pasting of colored paper and other processes.

[0048] Balancing blocks 12 are provided on both sides of the base 1 in the length direction to maintain the balance of the locking device.

[0049] In the locking device of the present application, balance blocks 12 are provided on both sides of the length direction of the base 1. The purpose of this arrangement is to maintain the balance of the entire device during operation. In actual use, especially when the bottle body rotates, the device may become unstable due to asymmetric weight distribution or external force. The design of the balance block 12 is intended to balance the overall center of gravity of the device by increasing the weight or support points on both sides of the base 1 to ensure its stability during operation.

[0050] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
