[0001] The utility model relates to the technical field of printing machines, and particularly relates to a temporary auxiliary component for a clamping mechanism of a printing machine. Background Technique

[0002] In the composition structure of a printing machine, the clamping mechanism thereon is generally composed of two telescopic rods arranged oppositely. Clamping ends are provided at the piston rod ends of the two telescopic rods. The two clamping ends make approaching or separating movements under the driving action of the corresponding telescopic rods. When in use, a material roll is placed between the two clamping ends, and then the two clamping ends are driven to make approaching movements to realize the clamping and bearing of the material roll.

[0003] Such as Figure 1 As shown, the telescopic rod structure supporting the printing machine is composed of a fixed cylinder 101, a movable rod 102 and a clamping end 103. After the movable rod makes a corresponding length telescopic movement on the fixed cylinder, it can be automatically clamped by a spring buckle 104 at the end of the fixed cylinder to keep the position of the movable rod stationary and prevent it from retracting. The cooperation of the two movable rods can realize the stable clamping of the material roll. However, during the use process, the spring buckle will cause component wear due to long-term use, or be damaged due to improper operation by technicians, resulting in a decline in the clamping effect of the spring buckle and making it difficult to exert a stable locking force on the movable rod. After the material roll is clamped and fixed by the movable rod, the spring buckle is difficult to firmly lock the movable rod, and the movable rod may make a retracting movement as shown by the arrow in the figure, resulting in the dropping of the material roll. Also, since this kind of telescopic rod structure is equipped for the printing machine itself, some connection parts are fixedly connected (such as welding), making it difficult to quickly and conveniently disassemble and replace the damaged telescopic rod structure, and the disassembly and replacement costs are also relatively high.

[0004] Therefore, we propose a temporary auxiliary component for a clamping mechanism of a printing machine to enable the clamping mechanism to still be used normally while maintaining this telescopic rod structure. Content of the Utility Model

[0005] The purpose of the utility model is to propose a temporary auxiliary component for a clamping mechanism of a printing machine to solve the problems in the prior art. The limiting part in this auxiliary component can be abutted and arranged between the clamping end and the fixed cylinder, preventing the movable rod and the clamping end from making retracting movements, and enabling the clamping action of the telescopic rod structure to be stably maintained.

[0006] To solve the above problems, the utility model provides the following technical solutions:

[0007] A temporary auxiliary component for a printing press clamping mechanism includes a limiting member disposed between a clamping end and a fixed cylinder end, such that the clamping end is kept at a constant distance from the fixed cylinder by the limiting member; the limiting member includes two baffles, which are detachably connected and can be mounted on the outside of a movable rod, and together form a limiting unit, with the two ends of the limiting unit arranged axially along the movable rod abutting against the clamping end and the fixed cylinder end, respectively.

[0008] As a further embodiment of this utility model: the baffle is designed in an arc shape so that when the two baffles are attached to the outside of the movable rod, they form a ring-shaped limiting assembly.

[0009] As a further embodiment of this utility model: the limiting components are configured as two sets and arranged along the axial direction of the movable rod. The distance between the two limiting components is adjustable so that when both limiting components are located outside the movable rod, the two ends of the two limiting components can respectively abut against the clamping end and the end of the fixed cylinder.

[0010] As a further embodiment of this utility model: a connecting block is slidably installed on any of the baffles of the limiting body along the axial direction of the movable rod. When both limiting bodies are located outside the movable rod, the connecting blocks on the two limiting bodies are arranged opposite to each other and can be detachably connected.

[0011] As a further embodiment of this utility model: the near ends of the two connecting blocks are respectively provided with protrusions and slots for inserting the protrusions.

[0012] As a further embodiment of this utility model: the protrusion is provided with a through hole, and the connecting block is provided with a pin that can pass through into the slot, so that when the protrusion is inserted into the slot, one end of the pin located in the slot can be inserted into the through hole, thereby achieving locking between the protrusion and the slot.

[0013] As a further embodiment of this utility model: the pin has a threaded section, the through hole has an internal thread, and the internal thread and the threaded section are designed to be compatible.

[0014] As a further embodiment of this utility model: the baffle plate is provided with a groove along the axial direction of the movable rod, and a slider for mounting the connecting block is slidably installed in the groove.

[0015] As a further embodiment of this utility model: both baffles located on the same limiting unit are provided with threaded holes, and fastening bolts can be inserted into the threaded holes to achieve a detachable connection between the two baffles.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By setting two limiting units at each end to abut against the clamping end and the fixed cylinder respectively, the retraction of the clamping end and the movable rod is effectively prevented, thus locking the position of the clamping end and ensuring stable and durable clamping action of the telescopic rod structure. For the clamping mechanism of printing equipment, this limiting unit design effectively solves the problem of insufficient locking force of the telescopic rod structure at a lower cost, greatly saving enterprise costs.

[0018] 2. The two baffles in the limiting component adopt a split design, which enables quick connection and disassembly of the limiting component. Both baffles are set to be arc-shaped, which can effectively hold the contact moving rod, making the limiting component a stable ring-shaped clamp, avoiding deformation caused by local stress concentration, and improving the overall stability of the limiting component.

[0019] 3. By setting two sets of adjustable limiters, and making the two sets of limiters connect and lock after adjustment, the two sets of limiters can be adapted to different distances between the clamping end and the fixed cylinder, so as to realize the abutment and locking of the clamping end in different extension states, thus expanding the scope of application.

[0020] 4. After the two limiting units abut against the clamping end and the fixed cylinder respectively, the two limiting units can be locked by bringing the two sets of connecting blocks close together and connecting them. The locking is convenient.

[0021] 5. Through the plug-in design of the protrusion and slot, not only can the two connecting blocks be adapted and pressed together, but the geometric matching of the protrusion and slot can achieve quick alignment, shorten the assembly time, and further optimize the connection efficiency.

[0022] 6. The locking structure of the pin and through hole can resist axial force and realize the quick connection and locking of the two connecting blocks. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1:

[0033] like Figure 2 As shown, a temporary auxiliary component for a printing press clamping mechanism is adapted to use with a telescopic rod structure in a printing press. It includes a limiting member for being disposed between the clamping end 103 and the end of the fixed cylinder 101. Specifically, after the material roll is clamped and supported by the clamping end 103 in the two telescopic rod structure, the movable rod 102 will extend to a corresponding length. At this time, the limiting member can be disposed between the clamping end 103 and the fixed cylinder 101 to maintain the position of the clamping end 103 and the fixed cylinder 101. Since the clamping end 103 is fixedly connected to the movable rod 102, the movable rod 102 will not retract, ensuring that the material roll is stably clamped and supported.

[0034] The limiting component includes two arc-shaped baffles 1. In use, the two baffles 1 are mounted on the outside of the movable rod 102 and are detachably connected. The two baffles 1 together form a limiting unit. The two ends of the limiting unit, arranged axially along the movable rod 102, abut against the clamping end 103 and the end of the fixed cylinder 101, respectively, thus preventing the movable rod 102 from retracting and ensuring the continuity and stability of the clamping action of the telescopic rod structure. Because the baffles 1 are arc-shaped, the limiting unit is annular and clamp-like, which makes the limiting unit more securely installed on the movable rod 102.

[0035] The detachable connection design of the two baffles 1 can be set by any conventional connection method in the prior art, such as bolting the two baffles 1 together, with threaded holes 9 on both baffles 1, and fastening bolts 10 can be inserted into the threaded holes 9 to achieve the connection.

[0036] Example 2:

[0037] like Figures 2-5 As shown, since the length of the limiting assembly along the axial direction of the movable rod 102 is fixed, it can only maintain and lock the clamping state when the distance between the clamping end 103 and the end of the fixed cylinder 101 is equal to the length of the limiting assembly. That is, it can only provide stable clamping assistance for a single type of length of material roll. Based on this, this application designs the limiting assembly into two sets, and the distance between the two sets of limiting assemblies can be adjusted and then connected and locked. This design allows the length of the two sets of limiting assemblies to be adapted to the corresponding distance between the clamping end 103 and the end of the fixed cylinder 101, thereby achieving clamping assistance for the telescopic rod structure within a certain range.

[0038] Specifically, the two sets of limiting components are arranged axially along the movable rod 102. In use, the two telescopic rods drive the two clamping ends 103 closer together to clamp and support the material roll. Then, both limiting components are mounted on the same movable rod 102, with one end of the limiting component abutting against the clamping end 103 and the other end abutting against the end of the fixed cylinder 101. Finally, the two limiting components are connected and locked. This state can be achieved by… Figure 5 This application utilizes a two-position adjustable limit system to achieve auxiliary locking of the clamping end 103 and the fixed cylinder 101 with different spacings, thus having a wide range of applications.

[0039] Example 3:

[0040] To achieve a locking connection after the two limit units are adjusted, a groove 7 is provided on the baffle 1 along the axial direction of the movable rod 102. A slider 8 is slidably installed on the groove 7, and a connecting block 2 is installed on the slider 8. When both limit units are held on the movable rod 102, the two limit units are driven to move away from each other until the two limit units are in contact with the clamping end 103 and the end of the fixed cylinder 101 respectively. Then, the connecting blocks 2 on the two baffles 1 are moved closer together until they press against each other. Then, the two connecting blocks 2 in the pressing state are connected and locked, thus achieving a lock between the two limit units. This allows the two limit units to maintain a contact state with the clamping end 103 and the end of the fixed cylinder 101 respectively, effectively preventing the retraction of the movable rod 102 and ensuring the long-term stability of the clamping action.

[0041] In order to enable the two connecting blocks 2 to fit and press against the movable rod 102, protrusions 3 and slots 4 for inserting the protrusions 3 can be provided at the close ends of the two connecting blocks 2 respectively. When the two connecting blocks 2 are close together, the positions of the two connecting blocks 2 can be positioned relative to each other by the insertion and cooperation of the protrusions 3 and the slots 4, which facilitates the connection and locking action of the two connecting blocks 2.

[0042] Based on the above design of protrusion 3 and slot 4, in order to better achieve the connection effect of the two connecting blocks 2, a through hole 5 can be opened on the protrusion 3, and a pin 6 that can pass through the slot 4 can be provided on the connecting block 2. When the protrusion 3 is inserted into the slot 4, one end of the pin 6 located in the slot 4 can be inserted into the through hole 5, so as to realize the pin connection and locking between the protrusion 3 and the slot 4.

[0043] Of course, the connection lock between the two connecting blocks 2 can also be set to other conventional designs in the prior art, such as threaded connection. In this case, the pin 6 needs to have a threaded section and the through hole 5 needs to have an internal thread. The internal thread and the threaded section are designed to be compatible, so as to achieve a stable threaded connection lock between the protrusion 3 and the slot 4.

[0044] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
