Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. It is understood that, without conflict, some technical means of the various embodiments described herein can be substituted for or combined with each other.

[0030] In the description of this utility model, the terms "first," "second," etc., are used only to distinguish the described objects and have no sequential or technical meaning. Therefore, objects specified with "first," "second," etc., may explicitly or implicitly include one or more of those objects. Furthermore, the words "one" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one, while "multiple" indicates at least two.

[0031] In the description of this utility model, references to "one embodiment" or "some embodiments" mean that one or more embodiments of the utility model include the specific features, structures, or characteristics described in connection with that embodiment. Therefore, the phrases "one embodiment," "some embodiments," "other embodiments," "and other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0032] This utility model provides a synchronous belt conveyor device for material conveying and facilitating equipment maintenance. (See reference...) Figure 1 In some embodiments, the synchronous belt conveyor includes a first conveyor line 10, a second conveyor line 20 and a third conveyor line 30 arranged sequentially along the conveying direction X.

[0033] Specifically, in conjunction with reference Figure 2 , Figure 3 , Figure 10 and Figure 11 The first conveyor line 10 has a first connecting plate 111 at its rear end, and the second conveyor line 20 has a second connecting plate 21 at its front end. The first connecting plate 111 and the second connecting plate 21 are connected by fastening bolts 23. The second conveyor line 20 has a third connecting plate 22 at its rear end, and the third conveyor line 30 has a fourth connecting plate 31 at its front end. The third connecting plate 22 and the fourth connecting plate 31 are connected by fastening bolts 23. It should be noted that the front end of each conveyor line refers to the end of the conveyor line corresponding to the upstream end in the conveying direction X, and the rear end of each conveyor line refers to the end of the conveyor line corresponding to the downstream end in the conveying direction X. Additionally, Figure 2 , Figure 3 , Figure 10 and Figure 11 The side frames of each conveyor line are hidden to facilitate observation of the structure of each conveyor line and avoid obstruction.

[0034] Each conveyor line has a synchronous pulley at both its front and rear ends, and a synchronous belt is wound around the pulley. Specifically, the first conveyor line 10 has a synchronous pulley 112 at its front and rear ends, and a synchronous belt 113 is wound around the pulley 112. The second conveyor line 20 has a synchronous pulley 24 at its front and rear ends, and a synchronous belt 25 is wound around the pulley 24. The third conveyor line 30 has a synchronous pulley 32 at its front and rear ends, and a synchronous belt 33 is wound around the pulley 32.

[0035] Furthermore, referring to Figure 2 The first conveyor line 10 is further provided with a first transmission gear 114 at its rear end. The first transmission gear 114 is coaxially connected to the synchronous pulley 112 at the rear end of the first conveyor line 10. The second conveyor line 20 is further provided with a second transmission gear 26 and a third transmission gear 27 at its front end. The second transmission gear 26 is coaxially connected to the synchronous pulley 24 at the front end of the second conveyor line 20. The central axis of the third transmission gear 27 is parallel to the central axis of the second transmission gear 26. The first transmission gear 114 and the second transmission gear 26 are respectively meshed with the third transmission gear 27.

[0036] In this invention, the synchronous belt conveyor features high strength and reliability. The conveyor lines are segmented and modular, with the first conveyor line 10 and the second conveyor line 20, and the second conveyor line 20 and the third conveyor line 30, detachably connected by fastening bolts 23. Each conveyor line can be independently disassembled and maintained, reducing equipment maintenance complexity. When the synchronous pulley 112 in the first conveyor line 10 drives the first transmission gear 114 to rotate, the first transmission gear 114 drives the third transmission gear 27 to rotate, and the third transmission gear 27 then drives the second transmission gear 26 to rotate. This allows the driving force of the first conveyor line 10 to be transmitted to the second conveyor line 20, achieving a compact layout, reducing energy consumption, and saving costs. When this synchronous belt conveyor is applied to a workstation, the second conveyor line 20 is positioned at the center of the workstation, the first conveyor line 10 corresponds to the loading position, and the third conveyor line 30 corresponds to the unloading position. Materials are loaded from the first conveyor line 10, processed by the workstation, and then unloaded from the third conveyor line 30. When maintaining the workstation equipment, simply disassemble the second conveyor line 20. This method is highly efficient, reduces labor intensity, and improves work efficiency.

[0037] In some preferred embodiments, each conveyor section is further provided with a tension adjustment assembly for adjusting the tension of the corresponding synchronous belt. The tension adjustment assembly includes a first idler pulley, a second idler pulley, and a drive pulley. The drive pulley is located between the first and second idler pulleys. The central axis of the first idler pulley, the central axis of the second idler pulley, and the central axis of the drive pulley are parallel to the central axis of the corresponding synchronous belt pulleys, respectively. The synchronous belt passes around the first idler pulley, the drive pulley, and the second idler pulley in sequence.

[0038] Furthermore, the tension adjustment assembly also includes an eccentric mounting structure, which includes a fixed shaft, an idler shaft, and a locking nut. The idler shaft is located at one axial end of the fixed shaft and is eccentrically positioned relative to the fixed shaft. The first idler and the second idler are rotatably mounted on their respective idler shafts. The fixed shaft is fixed to the side of the corresponding conveyor line by the locking nut.

[0039] Specifically, refer to Figure 3 and Figure 4 The first conveyor line 10 is equipped with a tension adjustment assembly 12, which can be used to adjust the tension of the synchronous belt 113. The tension adjustment assembly 12 includes a first idler pulley 121, a second idler pulley 122, and a drive pulley 123. The drive pulley 123 is located between the first idler pulley 121 and the second idler pulley 122. The first idler pulley 121, the second idler pulley 122, and the drive pulley 123 have a roughly "convex" shaped structure. The central axis of the first idler pulley 121, the central axis of the second idler pulley 122, and the central axis of the drive pulley 123 are parallel to the central axis of the synchronous belt pulley 112, respectively. The synchronous belt 113 passes sequentially around the first idler pulley 121, the drive pulley 123, and the second idler pulley 122. (Refer to...) Figures 4 to 6 The tension adjustment assembly 12 also includes an eccentric mounting structure 124, which includes a fixed shaft 1241, an idler shaft 1242, and a locking nut 1243. The idler shaft 1242 is located at one axial end of the fixed shaft 1241 and is eccentrically positioned relative to the fixed shaft 1241. The idler shaft 1242 can be integrally connected to the fixed shaft 1241. The first idler 121 and the second idler 122 are rotatably mounted on their respective idler shafts 1242. The fixed shaft 1241 is fixed to the side frame (not shown in the figure) of the first conveyor line 10 by the locking nut 1243. The first idler pulley 121 and the second idler pulley 122 are installed using an eccentric mounting structure 124. When it is necessary to adjust the tension of the synchronous belt 113, simply loosen the corresponding locking nut 1243 and rotate the corresponding fixed shaft 1241 to adjust the position of the corresponding idler pulley shaft 1242, that is, adjust the position of the first idler pulley 121 or the second idler pulley 122, thereby adjusting the tension of the synchronous belt 113. The operation is convenient, simple and reliable.

[0040] Reference Figure 10 The second conveyor line 20 is equipped with a tension adjustment assembly 29, which is used to adjust the tension of the synchronous belt 25. (Refer to...) Figure 11 The third conveyor line 30 is equipped with a tension adjustment assembly 34, which is used to adjust the tension of the synchronous belt 33. The structures of the tension adjustment assemblies 29 and 34 are similar to those of the tension adjustment assembly 12, and will not be described in detail here.

[0041] Furthermore, the first conveyor line 10 and the third conveyor line 30 are respectively equipped with drive components. The drive components include a geared motor, a drive gear, a driven gear, and a transmission belt. The geared motor drives and connects to the drive gear, the driven gear is coaxially connected to the corresponding drive wheel, and the transmission belt is sleeved on the drive gear and the driven gear.

[0042] Specifically, refer to Figure 3 and Figure 4The first conveyor line 10 is equipped with a drive assembly 13, which includes a geared motor 131, a drive gear 132, a driven gear 133, and a transmission belt 134. The geared motor 131 drives the drive gear 132, and the driven gear 133 is coaxially connected to the drive wheel 123. The transmission belt 124 is sleeved on the drive gear 132 and the driven gear 133. The inner side of the transmission belt 124 is provided with an internal tooth structure that matches the drive gear 132 and the driven gear 133. In application, the geared motor 131 drives the drive gear 132 to rotate. When the drive gear 132 rotates, it drives the driven gear 133 to rotate through the transmission belt 134. The driven gear 133 then drives the drive wheel 123 to rotate, thereby driving the synchronous belt 113 to run, and also driving the first idler pulley 121, the second idler pulley 122, and the synchronous pulleys 112 at both ends to rotate. Furthermore, the cylindrical surface of the drive wheel 123 is provided with a gear structure, which can increase the friction between the drive wheel 123 and the timing belt 113 and prevent slippage.

[0043] Reference Figure 11 The third conveyor line 30 is equipped with a drive assembly 35, which is used to drive the synchronous belt 33 to achieve material conveying. The structure of the drive assembly 35 is similar to that of the drive assembly 13, and will not be described in detail here.

[0044] Reference Figure 3 and Figure 7 A feed sensor 14 is provided at the front end of the first conveyor line 10. The feed sensor 14 is used to detect whether material has entered the first conveyor line 10. In application, the feed sensor 14 can be a photoelectric sensor, a contact sensor, a proximity sensor, or other products. When the material reaches the front end of the first conveyor line 10, the feed sensor 14 is triggered and feeds back the trigger signal to the electrical control system.

[0045] Reference Figure 7 and Figure 8 A stop assembly 15 is provided in the middle section of the first conveyor line 10. The stop assembly 15 includes a stop cylinder 151 and a stop block 152. The stop cylinder 151 is arranged vertically, and the stop block 152 is located at the top of the drive rod of the stop cylinder 151. When it is necessary to block the material, the stop cylinder 151 drives the stop block 152 to rise, and the stop block 152 can block the material.

[0046] In some embodiments, the first conveyor line 10 and the third conveyor line 30 are respectively provided with lifting assemblies. Each lifting assembly includes a lifting cylinder and a lifting plate. The lifting cylinder is arranged vertically, and the lifting plate is located on the top of the drive rod of the lifting cylinder. The lifting assembly is used to lift the material at the corresponding position, so as to facilitate the material picking or unloading operation of the workstation equipment.

[0047] Reference Figure 7The rear end of the first conveyor line 10 is sequentially provided with a first lifting assembly 16 and a second lifting assembly 17. The first lifting assembly 16 and the second lifting assembly 17 are used to support and lift the material, so that the workstation equipment can pick up the material and process it. (Refer to...) Figure 11 The third conveyor line 30 is equipped with a third lifting assembly 36 and a fourth lifting assembly 37 in sequence. These assemblies support the processed material and lower it onto the synchronous belt 33 for easy unloading. Figure 9 Taking the first lifting assembly 16 shown as an example, the first lifting assembly 16 includes a lifting cylinder 161 and a lifting plate 162. The lifting cylinder 161 is arranged vertically, and the lifting plate 162 is located at the top of the drive rod of the lifting cylinder 161. Of course, this utility model is not limited to this. In other embodiments, the number and position of the lifting assemblies can be reasonably set according to actual needs.

[0048] Furthermore, each lifting assembly is equipped with a position sensor, which is used to detect whether there is material present at the corresponding position. (Refer to...) Figure 7 or Figure 9 The first lifting assembly 16 has a position sensor 163 on its side, which can detect whether there is material on the lifting plate 162. Furthermore, the number of position sensors is not limited to one. For example, a position sensor 163 can also be set at the rear end of the first lifting assembly 16 to improve control accuracy and system reliability.

[0049] In some preferred embodiments, each conveyor section is further provided with a protective plate, which covers the corresponding synchronous belt, and the protective plates of the three conveyor sections are at the same height. (Refer to...) Figure 3 A protective plate 115 is provided on the first conveyor line 10, and the protective plate 115 covers the synchronous belt 113. (Refer to...) Figure 10 The second conveyor line 20 is equipped with a protective plate 28, which covers the synchronous belt 25. (See reference...) Figure 11 The third conveyor line 30 is equipped with a protective plate 38, which covers the synchronous belt 33.

[0050] In some preferred embodiments, the surfaces of synchronous belts 113, 25, and 33 are respectively provided with antistatic coatings. The antistatic coatings can protect the materials from static electricity and improve the safety and reliability of the equipment.

[0051] When the aforementioned synchronous belt conveyor is applied to a workstation, the second conveyor line 20 corresponds to the middle position of the workstation, the first conveyor line 10 corresponds to the loading position of the workstation, and the third conveyor line 30 corresponds to the unloading position of the workstation. Its workflow is as follows: S1: The first conveyor line 10 conveys materials along the conveying direction X. The first material is first conveyed to the second lifting component 17. The position sensor on the side of the second lifting component 17 detects the presence of the material and sends a feedback signal to the electrical control system. The electrical control system controls the synchronous belt 113 to decelerate. Then, the second lifting component 17 lifts the material at that position. S2: When the second material arrives at the first lifting assembly 16, the position sensor 163 on the side of the first lifting assembly 16 detects the presence of the material and sends a feedback signal to the electrical control system. The electrical control system controls the synchronous belt to decelerate, and then the first lifting assembly 16 lifts the material at that position. S3: The workstation equipment simultaneously removes the two materials from the first lifting assembly 16 and the second lifting assembly 17 for processing; afterwards, the first lifting assembly 16 and the second lifting assembly 17 descend. S4: After the first two materials are processed, the third lifting component 36 and the fourth lifting component 37 rise, and the station equipment places the two materials on the third lifting component 36 and the fourth lifting component 37 respectively; after placement, the third lifting component 36 and the fourth lifting component 37 drive the materials down to the synchronous belt 33, and the synchronous belt 33 drives the materials to be output.

[0052] In addition, when the third and subsequent materials enter the first conveyor line 10 and the first lifting component 16 and the second lifting component 17 have not yet descended, the blocking component 15 rises to block the third and subsequent materials; after the first lifting component 16 and the second lifting component 17 descend, the blocking component 15 descends, so that the third material reaches the second lifting component 17, and then the above steps are repeated.

[0053] In summary, this utility model provides a synchronous belt conveyor device, comprising a first conveyor line, a second conveyor line, and a third conveyor line arranged sequentially along the conveying direction. The first conveyor line is detachably connected to the second conveyor line, and the second conveyor line is detachably connected to the third conveyor line via fastening bolts. Each conveyor line can be independently disassembled and maintained, reducing the complexity of equipment maintenance. When maintaining the workstation equipment, only the second conveyor line needs to be disassembled, resulting in high operational efficiency, low labor intensity, and improved work efficiency. The first and second conveyor lines are connected by a transmission gear meshing structure, enabling a compact layout and reducing energy consumption. The synchronous belt has high strength and good reliability; each conveyor line is equipped with a tension adjustment assembly, and the idler wheel in the tension adjustment assembly is installed with an eccentric mounting structure, facilitating the adjustment of the synchronous belt tension and improving operational efficiency. Multiple sensors are installed on the conveyor lines to detect the material position, facilitating precise control of loading and unloading operations.

[0054] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
