Technical Field
[0001] This utility model relates to the technical field of paper processing equipment, and more specifically, to a support constraint adjustment mechanism and a paper storage rack. Background Technology
[0002] Paper storage racks in paper processing equipment are mainly used in printing, papermaking and other production processes to temporarily store and transport pre-processed paper, ensuring continuous supply and avoiding production interruptions. Their functions include stable paper feeding, adapting to different specifications of paper rolls or sheets, and integrating automation devices to achieve efficient production. In addition, the design of paper storage racks emphasizes safety and ease of maintenance, such as being equipped with tension adjustment, rust-proof materials and emergency stop devices to ensure the stability and reliability of the processing process. They are key equipment in paper processing production lines.
[0003] Currently, paper storage racks are used in paper processing equipment, and the internal paper storage space is adjustable to process paper of different sizes. The existing adjustment method is to first adjust one side of the baffle, place the paper, and then adjust the other side to clamp the paper. This operation is cumbersome and cannot quickly adjust to fit the paper. Utility Model Content
[0004] The purpose of this utility model is to provide a counterweight constraint adjustment mechanism and a paper storage rack. Through a synchronous transmission device, the first baffle and the second baffle can move synchronously in opposite directions or in opposite directions on the paper dropping platform. The movement is achieved through the cooperation of a rack and a connecting gear, which causes the connecting gear to drive the rack on the other side to move, which in turn causes the base on the other side to drive the other baffle to move. This enables synchronous adjustment and movement with one hand, improves the efficiency of paper space adjustment, and aims to solve the problems in the prior art.
[0005] This utility model is implemented as follows: a support constraint adjustment mechanism includes a paper-dropping platform. A first limiting groove and a second limiting groove are respectively provided at both ends of the paper-dropping platform. A first baffle and a second baffle are respectively provided between the first and second limiting grooves. The lower sides of the first and second baffles pass through the first and second limiting grooves and are respectively connected to the base at the bottom of the paper-dropping platform. A synchronous transmission device is provided between the two bases. The synchronous transmission device controls the movement of the two bases to achieve synchronous, opposite, or backward movement of the first and second baffles within the first and second limiting grooves.
[0006] Furthermore, the base is provided with fixing posts on both sides, the fixing posts are connected to the first baffle or the second baffle, and a connecting structure is provided on the fixing posts, the connecting structure passing through the first baffle or the second baffle to complete the fixation.
[0007] Furthermore, the synchronous transmission device includes a slide groove on the base, a fixed seat is provided inside the slide groove, and fixed screw holes are provided on both sides of the fixed seat. Screws provided in the fixed screw holes are used to fix the device to the paper dropping platform.
[0008] Furthermore, extension portions are provided on both sides of the bottom end of the fixed base, and the extension portions extend outward to the lower side of the base.
[0009] Furthermore, racks are provided on opposite sides of the two bases, and connecting gears are provided on the paper dropping platform between the racks, with the two ends of the connecting gears meshing with the two racks respectively.
[0010] Furthermore, a connecting shaft is provided in the middle of the connecting gear, one end of which is fixed to the paper dropping platform and the other end extends to the connecting frame.
[0011] Furthermore, both ends of the connecting frame extend to the outside of the connecting gear, and the ends are bent inward and fixed to the paper dropping platform.
[0012] Furthermore, both sides of the slide groove are arc-shaped, and both sides of the fixing seat are provided with abutment joints that are adapted to the slide groove.
[0013] Furthermore, both the first baffle and the second baffle are provided with connecting grooves at their bottom ends. The connecting structure includes a connecting screw, a washer is fitted on the outer wall of the connecting screw, a spring is provided at the lower part of the washer, the spring is fitted on the outer wall of the fixing column and is in a compressed state, and the connecting screw passes through the fixing column and extends into the connecting groove to realize the connection and fixation between the base and the first baffle or the second baffle.
[0014] Compared with the prior art, the counter-bracing constraint adjustment mechanism and paper storage rack provided by this utility model have the following beneficial effects:
[0015] 1. The synchronous transmission device enables the first and second baffles to move synchronously in opposite directions on the paper feeding platform. Users only need to adjust one end to adjust the diameter of the paper storage space. Pulling one side baffle causes the baffle to move the lower base in the first or second limiting groove. The movement is achieved through the cooperation of the rack and pinion and the connecting gear, which causes the connecting gear to move the rack on the other side, which in turn causes the base on the other side to move the other baffle. This enables synchronous adjustment with one hand and improves the efficiency of paper space adjustment.
[0016] 2. By extending the extension part under the fixed seat to the lower part of the base, the extension part can provide support for the base when the base moves, avoiding deformation of the base due to lack of support during long-term movement. In addition, the fixed seat and the sliding groove on the base cooperate to achieve precise directional movement of the base without deviation, ensuring the accuracy of the base's directional movement.
[0017] 3. The base and baffle are connected by connecting screws, washers and springs to ensure the reliability of the base's movement during operation. This provides tolerance compensation capability and effectively solves the problems of jamming or wear caused by cumulative errors, assembly tolerances and minor deformations during movement. This greatly improves the smoothness of the mechanism's operation and its lifespan. This is a key innovation to ensure the long-term reliable operation of the mechanism.
[0018] The paper storage rack includes a paper storage drawer, and the paper storage drawer is provided with a paper adjustment mechanism, which is the aforementioned counter-support constraint adjustment mechanism. Attached Figure Description

[0028] Reference Figure 1-5 As shown, the support constraint adjustment mechanism includes a paper-dropping platform 1. A first limiting groove 3 and a second limiting groove 5 are respectively provided at both ends of the paper-dropping platform 1. A first baffle 2 and a second baffle 4 are respectively provided between the first limiting groove 3 and the second limiting groove 5. The lower sides of the first baffle 2 and the second baffle 4 pass through the first limiting groove 3 and the second limiting groove 5, and are respectively connected to the base 6 at the bottom of the paper-dropping platform 1. A synchronous transmission device is provided between the two bases 6. The synchronous transmission device controls the movement of the two bases 6 to achieve synchronous opposite or opposite movement of the first baffle 2 and the second baffle 4 in the first limiting groove 3 and the second limiting groove 5. The synchronous transmission device enables the first baffle 2 and the second baffle 4 to move synchronously opposite or opposite on the paper-dropping platform 1, achieving synchronous adjustment movement with one hand and improving the efficiency of paper space adjustment.
[0029] In this embodiment, fixing posts 7 are provided on both sides of the base 6. The fixing posts 7 are connected to the first baffle 2 or the second baffle 4. A connecting structure 8 is provided on the fixing posts 7. The connecting structure 8 passes through the first baffle 2 or the second baffle 4 to complete the fixation. The bottom ends of the first baffle 2 and the second baffle 5 are provided with connecting grooves. The connecting structure 8 includes a connecting screw 81. A washer 82 is sleeved on the outer wall of the connecting screw 81. A spring 83 is provided at the lower part of the washer 82. The spring 83 is sleeved on the outer wall of the fixing post 7 and is in a compressed state. During connection, the compression is completed by the washer 82, causing the spring to... The spring 83 is in a compressed elastic state. The connecting screw 81 passes through the fixing post 7 and extends into the connecting groove to realize the connection and fixation between the base 6 and the first baffle 2 or the second baffle 4. The base 6 and the baffle are connected by connecting screw 81 + washer 82 + spring 83 to ensure the reliability of the movement of the base 6 during operation. This results in tolerance compensation capability, effectively solving the problems of jamming or wear caused by cumulative errors, assembly tolerances and minor deformations during movement. This greatly improves the smoothness of operation and life of the mechanism. This is a key innovation to ensure the long-term reliable operation of the mechanism.
[0030] Specifically, the lower part of the spring member 83 is sleeved on the outer wall of the fixed post 7, and the bottom extends into the groove on the base 6. Through the compression between the bottom wall of the groove and the gasket 82, the spring member 83 is in a compressed elastic state.
[0031] In this embodiment, the synchronous transmission device includes a slide groove 9 disposed on the base 6. A fixed seat 10 is disposed inside the slide groove 9. Fixed screw holes 15 are disposed on both sides of the fixed seat 10. Screws disposed in the fixed screw holes 15 are used to fix the device to the paper drop platform 1. An extension portion 14 is disposed on both sides of the bottom end of the fixed seat 10. The extension portion 14 extends outward to the lower side of the base 6. By extending the extension portion 14 disposed under the fixed seat 10 to the lower part of the base 6, the extension portion 14 can provide support for the base 6 when the base 6 moves, preventing the base 6 from deforming due to lack of support during long-term movement. Furthermore, the fixed seat 10 cooperates with the slide groove 9 on the base 6 to achieve precise directional movement of the base 6 without deviation, ensuring the accuracy of the directional movement of the base 6.
[0032] In this embodiment, racks 11 are provided on opposite sides of the two bases 6. A connecting gear 12 is provided on the paper drop platform 1 between the racks 11. The two ends of the connecting gear 12 mesh with the two racks 11 respectively. The user only needs to adjust one end to adjust the diameter of the paper storage space. Pulling one side baffle causes the baffle to move the lower base 6 in the first limiting groove 3 or the second limiting groove 5. The movement is achieved through the cooperation of the racks 11 and the connecting gear 12, which causes the connecting gear 12 to move the racks 11 on the other side, causing the base 6 on the other side to move the other baffle.
[0033] In this embodiment, a connecting shaft is provided in the middle of the connecting gear 12. One end of the connecting shaft is fixed on the paper drop platform 1, and the other end extends to the connecting frame 13. Both ends of the connecting frame 13 extend to the outside of the connecting gear 12, and the ends are bent inward and fixed to the paper drop platform 1, which serves to protect the connecting gear 12.
[0034] In this embodiment, both sides of the slide groove 9 are arc-shaped, and both sides of the fixing seat 10 are provided with abutment joints that are compatible with the slide groove 9 to reduce the impact force when sliding to the edge.
[0035] The paper storage rack includes a paper storage drawer, in which a paper adjustment mechanism is provided. The paper adjustment mechanism is the aforementioned counter-bracing constraint adjustment mechanism. The fixed base 10 cooperates with the sliding groove 9 on the base 6 to achieve precise directional movement of the base 6 without deviation, ensuring the accuracy of the directional movement of the base 6.
[0036] The user of this technical solution only needs to adjust one end to adjust the diameter of the paper storage space. Pulling one side baffle causes the baffle to move the lower base 6 in the first limiting groove 3 or the second limiting groove 5. The movement is achieved through the cooperation of the rack 11 and the connecting gear 12, which causes the connecting gear 12 to move the rack 11 on the other side, causing the base 6 on the other side to move the other baffle. The extension 14 provided under the fixed seat 10 extends to the lower part of the base 6. When the base 6 moves, the extension 14 can provide support for the base 6, preventing the base 6 from deforming due to lack of support during long-term movement. In this way, the synchronous transmission device enables the first baffle 2 and the second baffle 4 to move synchronously in opposite directions on the paper drop platform 1, realizing synchronous adjustment movement with one hand and improving the efficiency of paper space adjustment.
[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
