Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and specifically to a synchronous moving device. Background Technology

[0002] In the field of printing equipment technology, the horizontal position adjustment of the printing roller is a crucial step in ensuring the quality of printed products, and the rationality of its adjustment method directly affects the operating efficiency and operating costs of the equipment. Currently, the industry mainly relies on two technical solutions for adjusting the horizontal position of the printing roller: manual lead screw adjustment and motor adjustment. Manual lead screw adjustment relies entirely on manual rotation of the lead screw to adjust the position of the printing roller. While this method is simple in structure, it consumes a lot of manpower, especially when frequent adjustments or large adjustment strokes are required. This not only results in high labor intensity for operators but also low adjustment efficiency. Motor adjustment, on the other hand, uses a motor to drive the lead screw to complete the adjustment action. Compared to manual adjustment, it significantly improves labor-saving and convenience. However, this solution requires the installation of a motor, control circuit, and corresponding transmission auxiliary components. This not only significantly increases the overall manufacturing cost of the equipment but also makes the adjustment structure more complex, occupying more internal space. Its applicability is greatly limited in applications where compactness is a high priority. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a synchronous moving device, which solves the technical problems of high labor intensity and low adjustment efficiency of pure manual screw adjustment and increased cost and structure of motor-driven adjustment. This solution is more labor-saving, cost-saving, streamlined in structure and reduces space occupation.

[0004] To solve the above problems, the technical solution provided by this utility model is as follows:

[0005] A synchronous moving device includes symmetrically arranged housings and an adjusting handwheel and a worm gear built into the housings. The adjusting handwheel is coaxially connected to a worm gear body, which meshes with the worm gear. The end of the worm gear is provided with an end slot adapted to an electric screwdriver. A synchronous adjusting shaft is connected between the housings and coaxially connected to the worm gear. The worm gear body is coaxially fixed to an adjusting screw, which is connected to a sliding support for moving rollers.

[0006] By integrating manual adjustment with an adjustment structure compatible with power tools, it can meet the needs of manual operation by adjusting the handwheel, and can also achieve labor-saving adjustment by using the end slot with an electric screwdriver. At the same time, the synchronous adjustment shaft ensures the synchronicity of adjustment actions on both sides, effectively solving the problems of high labor intensity and low efficiency of pure manual adjustment. Moreover, it does not require a matching motor and control components, achieving the effects of cost saving, structural simplification and reduced space occupation.

[0007] Optionally, the synchronous adjustment shaft is provided with an elastic limiting component, which includes a patterned sleeve, a compression spring, and a limiting stop sleeve. The patterned sleeve and the compression spring are slidably sleeved on the synchronous adjustment shaft, the limiting stop sleeve is fixedly connected to the synchronous adjustment shaft, and the compression spring connects the patterned sleeve and the limiting stop sleeve.

[0008] The elastic limiting component is mainly used to elastically limit and buffer the axial movement of the synchronous adjustment shaft. It can limit the sliding range of the patterned sleeve through the elastic force of the compression spring, avoiding excessive displacement that could lead to component collisions or abnormal adjustment. It can also enhance the friction with related contact components through the patterned structure of the patterned sleeve, while the elastic deformation of the compression spring provides buffering, reducing rigid impacts during the operation of the synchronous adjustment shaft and ensuring the stability of the synchronous adjustment process.

[0009] Optionally, the synchronous adjustment shaft is provided with a waist-shaped keyway, and the patterned sleeve is provided with a pin that slides and limits the movement in conjunction with the waist-shaped keyway.

[0010] The combination of the waist-shaped keyway and the pin is mainly used to guide and limit the movement of the patterned sleeve. The structure of the pin being embedded in the waist-shaped keyway restricts the circumferential rotation of the patterned sleeve around the synchronous adjustment shaft, ensuring that it can only slide axially along the synchronous adjustment shaft. At the same time, the length range of the waist-shaped keyway limits the sliding stroke of the pin, thereby helping to constrain the axial sliding range of the patterned sleeve and ensuring the overall stability of the elastic limiting component.

[0011] Optionally, the housing has a hexahedral structure, with the adjustment handwheel installed on the outer facade, and a cover plate provided on the outer facade, with a rotating arrow groove structure for marking.

[0012] The hexagonal structure of the enclosure provides stable support for the internal adjustment components. The adjustment handwheel on the exterior allows for manual adjustment by the operator. The cover plate protects the internal structure of the enclosure, while the rotating arrow groove on the cover plate clearly indicates the rotation direction of the adjustment handwheel, assisting the operator in accurate operation and reducing adjustment errors.

[0013] Alternatively, the worm gear passes through the housing and is rotatably connected via a bearing seat.

[0014] The structure is designed to ensure stable installation and flexible rotation of the worm gear. The bearing housing provides support and positioning for the worm gear through a rotating connection, reducing frictional resistance during rotation. Simultaneously, the worm gear passing through the housing allows it to precisely mesh with the turbine body inside the housing. Furthermore, the bearing housing's support prevents wobbling during worm gear rotation, ensuring the stability of the meshing transmission between the worm gear and the turbine body, thereby guaranteeing the precision of the adjustment action.

[0015] Optionally, the inward end of the adjusting handwheel is provided with handwheel teeth, the adjusting handwheel slides axially along the thin section of the adjusting screw, the turbine body is provided with a tooth groove that mates with the handwheel teeth, and the handwheel teeth and tooth groove are detachable structures.

[0016] The structure is mainly designed to control the power transmission between the adjustment handwheel and the turbine body. By adjusting the handwheel and sliding it along the axial direction of the adjustment screw, the handwheel teeth can be engaged or disengaged from the tooth grooves of the turbine body. This allows the two to engage to transmit power when manual adjustment is needed, and to disengage when manual adjustment is not required (such as when using an electric screwdriver). This avoids interference caused by the synchronous rotation of the adjustment handwheel with the turbine body, and ensures the flexibility of switching adjustment modes.

[0017] Optionally, the adjusting handwheel has a fastening nut at its center, which is threaded to the end of the thin segment.

[0018] The fastening nut is mainly used to fix the axial position of the adjusting handwheel. Through the threaded connection with the end of the thin section of the adjusting screw, the adjusting handwheel can be stably locked in the required axial position (such as the state of the handwheel teeth engaging or disengaging with the tooth groove), to prevent the adjusting handwheel from sliding axially due to vibration or other accidents during equipment operation or adjustment, to ensure the stability of the engagement state of the handwheel teeth and tooth groove, and thus to ensure the reliability of the adjustment operation.

[0019] Optionally, the outer edge of the adjusting handwheel is provided with anti-slip texture.

[0020] The anti-slip texture on the outer edge of the adjusting handwheel is mainly used to enhance the friction when the operator holds the handwheel, preventing the hand from slipping during the rotation of the handwheel, thereby improving the stability and convenience of manual adjustment operation, and ensuring that the operator can drive the adjusting handwheel to rotate more effortlessly and accurately.

[0021] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0022] Firstly, the adjustment method is flexible and labor-saving. It can be operated manually by adjusting the handwheel, or driven by an electric screwdriver with the end slot. Compared with pure manual screw adjustment, it greatly reduces labor intensity and improves adjustment efficiency.

[0023] Secondly, it has lower cost and simpler structure, and does not require supporting components such as motors and control circuits. Compared with motor adjustment solutions, it saves manufacturing costs and reduces equipment space occupation, making it suitable for compact scenarios.

[0024] Thirdly, it has strong adjustment stability. The synchronous adjustment shaft ensures that the adjustment actions on both sides are synchronized, ensuring accurate adjustment of the horizontal position of the synchronous roller. The elastic limit component, combined with the waist-shaped keyway and the pin, can not only limit the sliding of the component and buffer the impact, but also prevent the circumferential rotation of the patterned sleeve, further maintaining stable operation.

[0025] Fourth, it is easy and reliable to operate. The anti-slip texture of the adjustable handwheel makes it easy to grip, the clutch structure can switch the power transmission state, the fastening nut can fix the position of the handwheel, and the box cover and arrow groove serve as protection and operation guidance, reducing operation errors and improving the overall user experience.

[0033] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments.

[0034] Example 1

[0035] Combined with appendixFigures 1-2 A synchronous moving device includes symmetrically arranged housings 1 and an adjusting handwheel 5 and a worm gear built into the housings 1, divided into a left adjusting housing 8 and a right adjusting housing 9. The adjusting handwheel 5 is coaxially connected to a worm gear body 11, which meshes with the worm gear. The end of the worm gear is provided with an end slot 6 adapted to an electric screwdriver. A synchronous adjusting shaft 3 is connected between the housings 1, and the synchronous adjusting shaft 3 is coaxially connected to the worm gear. The worm gear body 11 is coaxially fixed to an adjusting screw 7, which is connected to a sliding support for moving the roller.

[0036] Combined with appendix Figure 3 The sliding support is divided into a small sliding support 14 and a large sliding support 15. The large sliding support 15 is equipped with a slide rail, and the small sliding support 14 is slidably connected to this slide rail. The sliding supports are all symmetrically arranged. An anilox roller 12 is connected between two small sliding supports 14, and a printing roller 13 is connected between two large sliding supports 15. The moving device in this scheme is designed to control the distance and position of the anilox roller 12 and the printing roller 13. By rotating the adjusting handwheel 5 or using an electric screwdriver to engage the end slot 6, the worm gear is driven to rotate. The worm gear meshes with the turbine body 11, causing the turbine body 11 to rotate synchronously. Since the turbine body 11 is coaxially fixed to the adjusting screw 7, the rotation of the turbine body 11 will drive the adjusting screw 7 to rotate, thereby causing the sliding support connected to the adjusting screw 7 to move, thus realizing the position adjustment of the moving roller. At the same time, the two housings 1 are connected by the synchronous adjusting shaft 3. When the worm gear rotates, the synchronous adjusting shaft 3 moves in tandem, ensuring that the actions of the adjusting screws 7 on both sides are consistent, thus ensuring the stability of the horizontal position adjustment of the synchronous roller.

[0037] Combined with appendix Figure 4 , 6 The synchronous adjustment shaft 3 is provided with an elastic limiting component 4, which includes a patterned sleeve 401, a compression spring 402 and a limiting sleeve 403. The patterned sleeve 401 and the compression spring 402 are slidably sleeved on the synchronous adjustment shaft 3, the limiting sleeve 403 is fixedly connected to the synchronous adjustment shaft 3, and the compression spring 402 connects the patterned sleeve 401 and the limiting sleeve 403. When the synchronous adjusting shaft 3 undergoes axial displacement or the patterned sleeve 401 is subjected to external force, the patterned sleeve 401 will slide along the synchronous adjusting shaft 3. At this time, the compression spring 402 connected to the patterned sleeve 401 is compressed or stretched due to the sliding of the patterned sleeve 401. Since the limiting sleeve 403 is fixed to the synchronous adjusting shaft 3 and its position is fixed, it will limit the deformation range of the compression spring 402. In turn, the elastic reaction force of the compression spring 402 constrains the sliding stroke of the patterned sleeve 401, thereby achieving elastic limiting of the axial displacement of the synchronous adjusting shaft 3. At the same time, the patterned sleeve 401 adapts to the deformation of the compression spring 402 to maintain the stability of the limiting effect.

[0038] The synchronous adjusting shaft 3 is provided with a waist-shaped keyway 403, and the patterned sleeve 401 is provided with a pin that cooperates with the waist-shaped keyway 403 for sliding and limiting. When the patterned sleeve 401 slides along the synchronous adjusting shaft 3, the pin on the patterned sleeve 401 will be embedded in the waist-shaped keyway 403 of the synchronous adjusting shaft 3 and move together with the patterned sleeve 401; the groove wall of the waist-shaped keyway 403 will restrict the circumferential rotation of the pin, thereby preventing the patterned sleeve 401 from rotating relative to the synchronous adjusting shaft 3. At the same time, the length of the waist-shaped keyway 403 will limit the movement distance of the pin, thereby determining the axial sliding limit of the patterned sleeve 401, realizing the combined effect of directional sliding and stroke limiting.

[0039] Combined with appendix Figure 1 , 2 5. The housing 1 has a hexahedral structure with an adjustment handwheel 5 on the outer facade and a cover plate 2 on the outer facade. The cover plate 2 has a rotating arrow groove structure for marking. The hexahedral structure maintains the relative position stability of internal components such as worm gears and turbines through its own rigidity. The operator drives the internal adjustment components by rotating the adjustment handwheel 5 on the outer facade. The cover plate 2 covers the outer facade of the housing 1, preventing external debris from entering the interior. The rotating arrow groove on its surface provides visual guidance, allowing the operator to clearly understand the correspondence between the rotation direction of the handwheel and the movement direction of the synchronous roller, thereby operating in the correct direction to achieve precise adjustment.

[0040] The worm passes through the housing 1 and is rotatably connected to the bearing housing 10. After the worm passes through the housing 1, the bearing housing 10 provides fixed support for it. When the worm is driven to rotate, the bearing in the bearing housing 10 and the worm rotate relative to each other. The bearing housing 10 limits the radial wobble of the worm to maintain its axial position, and the bearing characteristics reduce the frictional resistance when the worm rotates, so that the worm can rotate smoothly and stably pass through the housing 1, thereby accurately meshing and transmitting power with the turbine body 11 inside the housing 1.

[0041] Combined with appendix Figure 4 The adjusting handwheel 5 has a handwheel tooth 501 at its inward end. The adjusting handwheel 5 slides axially along the thin segment 701 of the adjusting screw 7. The turbine body 11 has a tooth groove that engages with the handwheel tooth 501. The handwheel tooth 501 and the tooth groove are detachable. When manual adjustment is required, the adjusting handwheel 5 is axially slid along the thin segment 701 of the adjusting screw 7 toward the turbine body 11, so that the handwheel tooth 501 at the end of the adjusting handwheel 5 engages with the tooth groove of the turbine body 11. At this time, rotating the adjusting handwheel 5 causes the handwheel tooth 501 to drive the turbine body 11 to rotate synchronously through meshing with the tooth groove. When manual adjustment is not required, the adjusting handwheel 5 is slid away from the turbine body 11 along the thin segment 701 of the adjusting screw 7, and the handwheel tooth 501 disengages from the tooth groove. When the adjusting handwheel 5 rotates, it no longer transmits power to the turbine body 11, thereby realizing the switching between manual and non-manual adjustment states.

[0042] Combined with appendix Figure 5 The adjusting handwheel 5 has a locking nut 502 at its center, which is threaded to the end of the thin segment 701. When the adjusting handwheel 5 slides along the thin segment 701 of the adjusting screw 7 to the target position, the locking nut 502 at the center of the adjusting handwheel 5 is rotated. Because the locking nut 502 is threaded to the end of the thin segment 701, it will move along the thread of the thin segment 701 toward the adjusting handwheel 5 until it abuts against the adjusting handwheel 5. Through the locking force of the threaded connection, the locking nut 502 fixes the adjusting handwheel 5 and the thin segment 701 relative to each other, restricting the axial sliding of the adjusting handwheel 5. If it is necessary to adjust the position of the adjusting handwheel 5, the locking nut 502 is rotated in the opposite direction to loosen it, which will release the fixation and push the adjusting handwheel 5 to slide.

[0043] The outer edge of the adjusting handwheel 5 is provided with anti-slip texture. When the operator holds the outer edge of the adjusting handwheel 5, the anti-slip texture increases the static friction between the hand and the handwheel by increasing the roughness of the handwheel surface, reducing the possibility of the hand slipping relative to the handwheel, so that the rotational force applied by the operator can be transmitted to the adjusting handwheel 5 more stably, ensuring the effective execution of manual adjustment actions.

[0044] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
