Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, and in particular to a precision positioning device for offset printing machines. Background Technology

[0002] In past offset printing production practices, traditional positioning methods had many limitations. Early offset printing machine positioning mainly relied on manual experience and simple mechanical markings. Operators determined the position of the printing material by visual observation and manual adjustment. This method was not only inefficient, but the positioning accuracy was also greatly affected by human factors. Differences in the operating habits and skill levels of different operators would lead to inconsistent positioning results, making it difficult to guarantee the consistency and high quality of printed products.

[0003] The existing offset printing machine positioning device adopts a single-layer support structure, which makes it difficult to effectively distribute pressure. As a result, when the device bears the weight of the offset printing machine and its related components, it is prone to deformation due to excessive local pressure, causing the entire positioning device to shake and thus affecting the positioning accuracy of the offset printing machine. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a precision positioning device for offset printing machines.

[0005] This utility model is achieved by the following technical solution: a precision positioning device for offset printing machine, including a support mechanism, a sliding mechanism on the top of the support mechanism, and a lifting mechanism on the top of the sliding mechanism;

[0006] The support mechanism includes a first support plate, a support block fixedly connected to the top of the first support plate, a second support plate fixedly connected to the top of the support block, and a load-bearing plate fixedly connected to the top of the second support plate.

[0007] As a further improvement to the above solution, the top of the load-bearing plate is threaded with bolts, and the load-bearing plate is threadedly connected to the second support plate. Connecting columns are provided on both sides of the support block, and the bottom and top of the connecting columns are fixedly connected to the first support plate and the second support plate, respectively.

[0008] Through the above technical solution, the supporting mechanism can provide basic support for the entire precision positioning device. The first support plate serves as the bottom support, dispersing the pressure of the device on the ground or mounting surface. The support block increases the overall height and strengthens the structural stability. The second support plate further expands the support area, and the load-bearing plate directly bears the weight of the offset printing machine's related components, ensuring that the device will not shake or deform due to pressure during operation, thus improving the stability of the device.

[0009] As a further improvement to the above solution, the sliding mechanism includes a fixed block, the top of which has a groove, a limiting shaft is fixedly connected in the groove, and a sliding block is sleeved on the surface of the limiting shaft.

[0010] As a further improvement to the above solution, a base is fixedly connected to the top of the sliding block, and a connecting rod is provided on one side of the base, with both sides of the connecting rod fixedly connected to the base.

[0011] Through the above technical solution, the sliding mechanism and the limiting shaft provide precise guidance for the sliding block, enabling the sliding block to slide smoothly along the limiting shaft in the groove. This allows for precise position adjustment in the horizontal direction, providing a reliable basis for the lateral positioning of the offset printing machine and helping to improve the positioning accuracy of the printing material in the lateral position.

[0012] As a further improvement to the above solution, the lifting mechanism includes a first lifting block, a second lifting block is sleeved inside the first lifting block, the second lifting block extends to the top of the first lifting block, a first connecting block and a second connecting block are fixedly connected to one side of the first lifting block and the second lifting block respectively, a first lifting rod is fixedly connected to the top of the first connecting block, and a second lifting rod is sleeved on the top of the first lifting rod.

[0013] As a further improvement to the above solution, a limiting plate is provided on the side of the first lifting block away from the first connecting block, and both sides of the limiting plate are fixedly connected to the first lifting block. A snap-fit ​​block is fixedly connected on the side of the second lifting block away from the second connecting block, and a snap-fit ​​plate is snapped into the snap-fit ​​block.

[0014] Through the above technical solution, the lifting mechanism is set up, which is connected to a first lifting block and a second lifting block, respectively. The first lifting block and the second lifting block are connected to a first connecting block and a second connecting block, and the height is adjusted through the first lifting rod and the second lifting rod. Thus, the overall height of the device can be flexibly adjusted according to the different working requirements of the offset printing machine, which greatly improves the versatility and applicability of the device.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention provides a foundation for the entire precision positioning device through a supporting mechanism. The first support plate serves as the bottom support, dispersing the pressure of the device on the ground or mounting surface. The support block increases the overall height and strengthens the structural stability. The second support plate further expands the support area, while the load-bearing plate directly bears the weight of the offset printing machine's components, ensuring that the device will not shake or deform under pressure during operation, thus improving the device's stability. The sliding mechanism provides precise guidance for the sliding block's movement via a limiting shaft, allowing the sliding block to slide smoothly along the limiting shaft within the groove. This enables precise horizontal position adjustment, providing a reliable foundation for the offset printing machine's lateral positioning and improving the positioning accuracy of the printing material in the lateral direction. The lifting mechanism, connected to a first and second lifting block via a first and second connecting block respectively, and further adjusted via a first and second lifting rod, allows for flexible adjustment of the overall height of the device according to different working requirements of the offset printing machine, greatly improving the device's versatility and applicability.

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example

[0024] Please combine Figure 1-4The present embodiment of a precision positioning device for an offset printing machine includes a support mechanism 1, a sliding mechanism 2 is provided on the top of the support mechanism 1, and a lifting mechanism 3 is provided on the top of the sliding mechanism 2.

[0025] The support mechanism 1 includes a first support plate 101, a support block 102 fixedly connected to the top of the first support plate 101, a second support plate 103 fixedly connected to the top of the support block 102, and a load-bearing plate 104 fixedly connected to the top of the second support plate 103.

[0026] The top of the load-bearing plate 104 is threaded with bolts, and the load-bearing plate 104 is threadedly connected to the second support plate 103. Both sides of the support block 102 are provided with connecting columns, and the bottom and top of the connecting columns are fixedly connected to the first support plate 101 and the second support plate 103, respectively.

[0027] The sliding mechanism 2 includes a fixed block 201, the top of the fixed block 201 is provided with a sliding groove, a limiting shaft 202 is fixedly connected in the sliding groove, and a sliding block 203 is sleeved on the surface of the limiting shaft 202.

[0028] The top of the sliding block 203 is fixedly connected to the base 204, and a connecting rod is provided on one side of the base 204. Both sides of the connecting rod are fixedly connected to the base 204.

[0029] The lifting mechanism 3 includes a first lifting block 301, a second lifting block 302 is sleeved inside the first lifting block 301, the second lifting block 302 extends to the top of the first lifting block 301, a first connecting block and a second connecting block are fixedly connected to one side of the first lifting block 301 and the second lifting block 302 respectively, a first lifting rod is fixedly connected to the top of the first connecting block, and a second lifting rod is sleeved on the top of the first lifting rod.

[0030] A limiting plate 303 is provided on the side of the first lifting block 301 away from the first connecting block. Both sides of the limiting plate 303 are fixedly connected to the first lifting block 301. A snap-fit ​​block is fixedly connected on the side of the second lifting block 302 away from the second connecting block. A snap-fit ​​plate is snapped into the snap-fit ​​block.

[0031] The implementation principle of this utility model is as follows: Based on the lateral position requirements of the printing material in the offset printing machine, the sliding block 203 is pushed to slide on the limiting shaft 202. Due to the guiding effect of the limiting shaft 202, the sliding block 203 can smoothly drive the base 204 and the lifting mechanism 3 above it to move horizontally, thereby achieving precise positioning of the offset printing machine in the lateral direction. According to the thickness of the printing material or the vertical requirements of the printing position, the lifting mechanism 3 is adjusted. By stretching or compressing the first and second lifting rods, the second lifting block 302 rises or falls within the first lifting block 301. When the appropriate height is reached, the locking block is engaged with the locking plate to fix the position of the second lifting block 302, completing the vertical positioning adjustment of the offset printing machine.
