Detailed implementation manners

[0032] The following will describe in detail the specific implementation manners of the present utility model with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and illustrating the present utility model, and are not used to limit the present utility model.

[0033] In the present utility model, unless otherwise stated, the orientation terms such as "upper, lower, inner, outer" included in the terms only represent the orientation of the terms in the normal use state, or the common names understood by those skilled in the art, and should not be regarded as a limitation to the terms.

[0034] Refer to Figures 1-8 As shown, a 3D printing belt adjusting device, the adjusting device includes: a feedback mechanism 200 and a pressing mechanism 300 disposed on a horizontal slide rail 103 of a printer body; wherein, the horizontal slide rail 103 is horizontally slidably disposed on a support mechanism, a belt body 104 is installed in the horizontal slide rail 103 through a transmission wheel, the feedback mechanism 200 and the pressing mechanism 300 are both fixedly disposed on the side of the horizontal slide rail 103 and above the belt body 104, the pressing mechanism 300 is used to adjust the tension degree of the belt body 104 during work, and the feedback mechanism 200 is installed adjacent to the pressing mechanism 300, and is used to detect the tension degree of the belt body 104 in the horizontal slide rail 103 and directly reflect the adjustment effect of the pressing mechanism 300 on the belt body 104.

[0035] During use, the pressing mechanism 300 and the feedback mechanism 200 are both firmly installed on the side of the horizontal slide rail 103 and above the belt body 104. The feedback mechanism 200 captures minute changes in the belt tension state. When it is necessary to adjust the tension degree of the belt body 104, the pressing mechanism 300 applies downward pressure to the belt body 104, thereby changing its tension state. During this process, the adjustment amount of the pressing mechanism 300 can be intuitively reflected by the feedback mechanism 200, which can achieve fine control of the tension degree of the belt body 104, improve the adjustment accuracy and stability, reduce wear and faults caused by the belt being too tight or too loose, extend the service life of the belt, and reduce the maintenance cost.

[0036] Refer to Figures 3-5As shown in the figure, the feedback mechanism 200 includes: a first mounting base 201, a lower pressing roller 203, a sliding rod 204, a spring 210, a first slider 211, and an upper pressing roller 212. Among them, the first mounting base 201 is fixedly installed on the side of the horizontal slide rail 103 and a plurality of lower pressing rollers 203 that are in contact with the inner side wall of the belt body 104 are fixedly arranged at intervals on one side close to the belt body 104. A sliding rod 204 is slidably arranged on the first mounting base 201 on one side close to the belt body 104. An upper pressing roller 212 that is located between two lower pressing rollers 203 and is in contact with the outer side wall of the belt body 104 is fixedly arranged on the side surface of the sliding rod 204. A first slider 211 is fixedly arranged on its back surface. A first sliding groove 209 for the first slider 211 to slide is formed on the first mounting base 201. A spring 210 is fixedly arranged in the first sliding groove 209. The other end of the spring 210 is in contact with the upper surface of the first slider 211. A feedback member for directly observing the tension degree of the belt body 104 is arranged on the surface of the first mounting base 201.

[0037] In the above solution, when the belt body 104 runs under the action of the driving wheel, its inner side wall will continuously contact the lower pressing roller 203. However, since the lower pressing roller 203 is fixed, they mainly play a role in positioning and guiding. As the tension degree of the belt body 104 changes, the contact force between its upper side wall and the upper pressing roller 212 will also change. The upper pressing roller 212 is connected to the first slider 211 through the sliding rod 204, and the first slider 211 slides in the first sliding groove 209, and a spring 210 is arranged in this sliding groove. When the belt is tightened, the upper pressing roller 212 will be subjected to a greater pressure, pushing the first slider 211 to move inward in the sliding groove and simultaneously compressing the spring 210. On the contrary, when the belt is loose, the spring 210 will release energy, pushing the first slider 211 and the upper pressing roller 212 to move outward to restore contact with the belt. A feedback member is arranged on the surface of the first mounting base 201, which is used to directly observe or measure the displacement change generated by the compression or release of the spring 210, so as to indirectly reflect the tension degree of the belt body 104.

[0038] Refer to Figure 4 As shown in the figure, the feedback member includes: a rack 205, a gear 206, a pointer 207, and a scale line 208. Among them, a rack 205 is fixedly arranged on the side surface of the sliding rod 204. A gear 206 is rotatably arranged on the first mounting base 201. The gear 206 meshes with the rack 205 and a pointer 207 is fixedly arranged on its side surface. A scale line 208 that is used in cooperation with the pointer 207 is arranged on the first mounting base 201.

[0039] In the above solution, when the belt body 104 runs under the action of the driving wheel, its tension degree will change. This change will cause the upper pressure roller 212 to be subjected to different degrees of pressure, thereby pushing the sliding rod 204 to slide in the chute of the first mounting seat 201. Since the rack 205 is fixed to the sliding rod 204, the sliding of the sliding rod 204 will drive the rack 205 to move. The rack 205 meshes with the gear 206, so the movement of the rack 205 will drive the gear 206 to rotate. As the gear 206 rotates, the pointer 207 fixed to the side of the gear 206 will also rotate accordingly. The rotation of the pointer 207 will cause it to point to different positions on the scale line 208, and these positions represent different belt tension degrees. The operator can directly read the current tension degree of the belt body 104 by observing the position of the pointer 207 on the scale line 208.

[0040] Referring to Figures 3-6 As shown, the pressing mechanism 300 includes: a second mounting seat 301, a sliding bracket 302, a pressure roller 303 and a second slider 305; wherein, the second mounting seat 301 is vertically and fixedly installed on the side of the horizontal slide rail 103, and the inner wall of the second mounting seat 301 slidably provides a sliding bracket 302. The sliding bracket 302 is located above the belt body 104, and the inner wall of the sliding bracket 302 rotatably provides a pressure roller 303 that abuts against the outer side wall of the horizontal slide rail 103. Opposite side surfaces of the sliding bracket 302 are fixedly provided with second sliders 305, and the inner side wall of the second mounting seat 301 is provided with a second chute 304 for the second sliders 305 to slide. The second mounting seat 301 is provided with an adjusting member for driving the sliding bracket 302 to slide vertically in the second mounting seat 301.

[0041] In the above solution, the second mounting seat 301 is provided with an adjusting member for controlling the up and down movement of the sliding bracket 302. When it is necessary to adjust the tension degree of the belt body 104, the operator operates the adjusting member to drive the sliding bracket 302 to slide vertically in the second mounting seat 301. As the sliding bracket 302 moves downward, the pressure applied by the pressure roller 303 to the belt body 104 gradually increases, thereby increasing the tension degree of the belt. On the contrary, if the sliding bracket 302 moves upward, the tension degree of the belt will decrease. During this process, the feedback mechanism 200 can be combined to monitor the tension degree of the belt in real time, and the position of the sliding bracket 302 can be continuously adjusted according to the need until the ideal tension state is reached. By precisely adjusting the tension degree of the belt, the operating state of the equipment can be optimized, the printing accuracy and production efficiency can be improved, and at the same time, the failures and downtime caused by belt slack or over-tightening can be reduced.

[0042] Referring to Figure 6As shown, the adjusting member includes a screw rod 306 and a rotating handle 307. The screw rod 306 is vertically arranged and threadedly penetrates through the second mounting seat 301. Its bottom surface is fixedly connected to the upper surface of the sliding bracket 302, and a rotating handle 307 is fixedly provided on the top surface of the screw rod 306.

[0043] When it is necessary to adjust the tension of the belt body 104, the operator rotates the rotating handle 307 to drive the screw rod 306 to move downward under the action of the thread. Since the screw rod 306 is fixedly connected to the sliding bracket 302, the sliding bracket 302 will also move downward accordingly, and the pressure exerted by the pressure roller 303 on the belt body 104 increases, and the tension of the belt increases. If it is necessary to reduce the tension of the belt, then rotate the rotating handle 307 in the reverse direction, and the screw rod 306 and the sliding bracket 302 will move upward accordingly, and the pressure of the pressure roller 303 on the belt decreases, and the tension of the belt decreases.

[0044] Refer to Figure 3 As shown, the second mounting seat 301 is fixedly installed on the side surface of the horizontal slide rail 103 through the second bolt 308, and the first mounting seat 201 is fixedly installed on the side surface of the horizontal slide rail 103 through the first bolt 202.

[0045] In the above solution, the second mounting seat 301 and the first mounting seat 201 are respectively fixed on the side surface of the horizontal slide rail 103 through the second bolt 308 and the first bolt 202, which enhances the structural stability of the entire adjusting device and prevents loosening or falling off caused by vibration or impact during the operation of the equipment. The design of bolt connection makes the installation process simple and fast, and at the same time is also convenient for subsequent maintenance and replacement of components. When it is necessary to disassemble or replace the mounting seat, just loosen the bolt and it can be easily removed.

[0046] Refer to Figures 1-2 As shown, the printer body includes a printing base 100 and a printing bracket 102. The printing bracket 102 is fixedly arranged on both sides of the upper surface of the printing base 100 that are far away from each other, and the horizontal slide rail 103 is slidably sleeved on the printing bracket 102.

[0047] In the above solution, the horizontal slide rail 103 is firmly supported on the printing base 100 through the printing bracket 102, providing a solid support foundation for the entire adjusting device and ensuring the stability of the equipment during operation.

[0048] Refer to Figures 1-2 As shown, a printing plate 101 is slidably arranged at the middle position of the top of the printing base 100.

[0049] In the above solution, according to the requirements of the printing task, the position of the printing plate 101 on the sliding track is adjusted manually or automatically to ensure that the printed object can be accurately placed in the predetermined printing area, enabling the user to flexibly adjust its position according to the requirements of the printing task, thereby adapting to printed objects of different sizes and shapes.

[0050] In summary, for the 3D printing belt adjusting device provided by the present utility model, during use, as the tension degree of the belt body 104 changes, the contact force between its upper side wall and the upper pressure roller 212 also changes. This change causes the upper pressure roller 212 to be subjected to different degrees of pressure, which in turn pushes the sliding rod 204 to slide in the chute of the first mounting seat 201. Since the rack 205 is fixed to the sliding rod 204, the sliding of the sliding rod 204 drives the rack 205 to move. The rack 205 meshes with the gear 206, so the movement of the rack 205 drives the gear 206 to rotate. As the gear 206 rotates, the pointer 207 fixed to the side of the gear 206 also rotates accordingly. The rotation of the pointer 207 causes it to point to different positions on the scale line 208, and these positions represent different belt tension degrees. The operator can directly read the current tension degree of the belt body 104 by observing the position of the pointer 207 on the scale line 208. When it is necessary to adjust the tension degree of the belt body 104, the operator drives the sliding bracket 302 to slide vertically in the second mounting seat 301 by operating the adjusting member. As the sliding bracket 302 moves downward, the pressure exerted by the pressure roller 303 on the belt body 104 gradually increases, thereby increasing the belt tension degree. On the contrary, if the sliding bracket 302 moves upward, the belt tension degree will decrease. During this process, the feedback mechanism 200 can be combined to monitor the belt tension degree in real time and continue to adjust the position of the sliding bracket 302 as needed until the ideal tension state is reached, by precisely adjusting the belt tension degree.

[0052] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without contradiction. To avoid unnecessary repetition, the present utility model will not separately describe various possible combination methods.

[0053] Furthermore, any combination can be made between different embodiments of the present utility model as long as it does not violate the idea of the present utility model, and it should equally be regarded as the content disclosed by the present utility model.
