Description

Technical Field

[0001] This utility model relates to a waste discharge machine, and more particularly to an adaptive chain drive structure for a pneumatic waste discharge machine. Background Technology

[0002] Ordinary waste removal machines use punches to remove the pre-cut graphic blocks from the pearl cotton sheet.

[0003] However, the above-mentioned waste removal machine (application number: 202220680582.2, utility model name: conveyor belt type CNC waste removal machine) uses a punch frame to drive the punch rod down, which punches the graphic block corresponding to the punch rod out of the pearl cotton board, thereby realizing the separation of the graphic block from the pearl cotton board material.

[0004] The aforementioned waste removal machine has a complex structure, requiring the installation of numerous punches on the punching frame. Furthermore, once the pearl cotton sheet with different shaped graphic blocks is replaced, the position and number of punches need to be readjusted, which is not only time-consuming but also labor-intensive for operators and results in low production efficiency. Therefore, the applicant has designed a pneumatic waste removal machine to solve the above problems.

[0005] The pneumatic waste discharge machine of this application uses an upper drive roller and a lower drive roller to clamp the material plate and drive the material plate forward, thereby realizing the continuous passage of the material through the air knife. However, because the thickness of the material plate varies, the height of the upper drive roller needs to be adjusted according to the thickness of the material plate. Therefore, the upper drive roller is set on a lifting frame to achieve lifting and lowering. Based on the above purpose, this application designs an adaptive chain drive structure to ensure that after the upper drive roller is lifted and lowered, the lower drive roller can also drive the upper drive roller to rotate through the adaptive chain drive structure. Utility Model Content

[0006] In order to overcome the shortcomings of the existing technology, this utility model provides an adaptive chain drive structure for a pneumatic waste discharge machine.

[0007] The technical solution adopted by this utility model to solve its technical problem is:

[0008] An adaptive chain drive structure for a pneumatic waste discharge machine is characterized by comprising a roller drive mechanism, an elastic tensioning mechanism, a transmission chain one, a sprocket one mounted on the lower drive roller, sprockets two and three mounted on the upper drive roller, and a sprocket four mounted on a lifting frame. The lower drive roller is mounted on the frame and rotates via the roller drive mechanism. The transmission chain one is mounted on sprockets one, two, three, and four. Sprocket three is mounted on the frame via the elastic tensioning mechanism, and the elastic tensioning mechanism can apply an elastic force to tighten the transmission chain. The lower drive roller drives the upper drive roller to rotate via the transmission chain one.

[0009] The roller drive mechanism includes a roller drive motor, a sprocket five mounted on the roller drive motor, a sprocket six mounted on the lower drive roller, and a transmission chain two mounted on sprocket five and sprocket six.

[0010] The elastic tensioning mechanism includes an adaptive spring, a self-adjusting frame, and a fixed base fixed to the frame. The sprocket three is disposed on the self-adjusting frame, and the adaptive spring is disposed between the self-adjusting frame and the fixed base and can apply an elastic force to the self-adjusting frame, thereby tensioning the transmission chain through the sprocket three.

[0011] The fixed base is provided with a mounting groove. The self-adjusting frame includes a base plate and side plates disposed opposite to each other on the base plate. The base plate is located below the fixed base and the side plates are located on both sides of the fixed base. The groove wall of the mounting groove is provided with a clearance elongated hole. The sprocket is disposed on the side plate through a bearing and a rotating shaft, and the rotating shaft passes through the clearance elongated hole. The adaptive spring is disposed between the base plate and the fixed base.

[0012] The sprockets three and four are positioned opposite and below sprocket one, thus forming a V-shape in the transmission chain one.

[0013] The end of the rotating shaft is provided with a limiting surface, which can abut against the wall of the avoidance elongated hole to restrict the rotation of the rotating shaft.

[0014] The beneficial effects of this utility model are: This utility model uses sprocket three and sprocket four as tensioning wheels, and with the cooperation of the elastic tensioning mechanism, elastic force is applied to sprocket three to tighten the transmission chain, which ensures that the transmission chain one can be tensioned after the upper drive roller is raised and lowered, thereby ensuring that the upper drive roller can be driven by power in the position within the lifting and lowering range.

Furthermore, this disclosure is limited only by the scope of the claims.

Throughout this specification, the same reference numerals refer to the same elements. In the following description, detailed descriptions of relevant known functions or configurations will be omitted where it is determined that such detailed descriptions would unnecessarily obscure the focus of this disclosure.

[0026] As will be fully understood by those skilled in the art, the features of the different embodiments of this disclosure may be coupled or combined with each other in part or in whole, and may cooperate with each other and be technically driven in various ways. The embodiments of this disclosure may be implemented independently of each other, or may be implemented together in an interdependent relationship.

[0027] Reference Figure 1 , Figure 2This utility model discloses an adaptive chain drive structure for a pneumatic waste discharge machine, including a roller drive mechanism, an elastic tensioning mechanism, a transmission chain 1, a sprocket 11 mounted on the lower drive roller, a sprocket 12 and a sprocket 13 mounted on the upper drive roller 100, and a sprocket 14 mounted on the lifting frame 300. The upper drive roller 100 is also mounted on the lifting frame 300. The lower drive roller 200 is mounted on the frame and rotates via the roller drive mechanism. The transmission chain 1 is mounted on sprockets 11, 12, 13, and 14. The sprocket 13 is tensioned by the elastic tensioning mechanism. The transmission chain 11 is tensioned by applying elastic force through the elastic tensioning mechanism on the frame and the sprocket 3 13. The lower drive roller 200 drives the upper drive roller 100 to rotate through the transmission chain 11. In the above structure, sprocket 3 13 and sprocket 4 14 are tensioning wheels that are not connected to the drive roller. Sprocket 3 13, in conjunction with the elastic tensioning mechanism, maintains tension on the transmission chain 11, thereby ensuring good cooperation between the transmission chain 11, sprocket 11, and sprocket 2 12. This ensures that the transmission chain 11 remains tensioned after the upper drive roller 100 is raised or lowered, thus ensuring that the upper drive roller 100 has power to drive it after raising or lowering.

[0028] Specifically, sprockets 13 and 14 are positioned relative to and below sprocket 11, thus forming a V-shape with the transmission chain 1. This arrangement allows sprockets 13 and 14 to apply tension to the transmission chain 1 symmetrically. Furthermore, when the upper drive roller 100 descends, sprocket 14 also descends, while sprocket 13 moves under the tension of the elastic tensioning mechanism, thereby preventing the transmission chain 1 from becoming slack.

[0029] like Figure 3 and Figure 4 As shown, the elastic tensioning mechanism includes an adaptive spring 3, a self-adjusting frame 4, and a fixed base 5 fixed to the frame. The sprocket 3 13 is disposed on the self-adjusting frame 4. The adaptive spring 3 is disposed between the self-adjusting frame 4 and the fixed base 5 and can apply an elastic force to the self-adjusting frame 4, thereby tensioning the transmission chain 1 through the sprocket 3 13. The above structure pushes the self-adjusting frame 4 through the elastic force of the adaptive spring 3, thereby driving the sprocket 3 13 to tension the transmission chain 1.

[0030] Specifically, the fixed base 5 is provided with a mounting groove 51, and the self-adjusting frame 4 includes a base plate 41 and side plates 42 disposed opposite to each other on the base plate 41. The base plate 41 is located below the fixed base 5 and the side plates 42 are located on both sides of the fixed base 5. The groove wall of the mounting groove 51 is provided with a clearance elongated hole 6. The sprocket 3 13 is disposed on the side plate 42 via a bearing and a rotating shaft 7, and the rotating shaft 7 passes through the clearance elongated hole 6. The adaptive spring 3 is disposed between the base plate 41 and the fixed base 5. Through the above structure, one end of the adaptive spring 3 abuts against the bottom surface of the fixed base 5, and the other end of the adaptive spring 3 abuts against the base plate 41, thereby causing the sprocket 3 13 to tension the transmission chain 1 by pulling the rotating shaft 7 through the self-adjusting frame 4.

[0031] As shown in the figure, the end of the rotating shaft 7 is provided with a limiting surface (not shown in the figure), which can abut against the wall of the avoidance elongated hole 6 to restrict the rotation of the rotating shaft 7.

[0032] In this application, the roller drive mechanism includes a roller drive motor 400, a sprocket 15 disposed on the roller drive motor 400, a sprocket 16 disposed on the lower drive roller 200, and a transmission chain 2 disposed on the sprocket 15 and the sprocket 16. Through the above structure, the roller drive motor 400 can drive the lower drive roller 200 to rotate.

[0033] The above provides a detailed description of the adaptive chain drive structure for a pneumatic waste discharge machine provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
