Auxiliary material returning mechanism and cutting guide machine

Abstract

The application provides an auxiliary material returning mechanism and a cutting machine. The auxiliary material returning mechanism comprises a support frame fixed relative to a support structure of a conveying device, a roller support slidingly assembled on the support frame, and a roller rotatably connected with the roller support. An axis around which the roller rotates is perpendicular to a sliding direction of the roller support. The auxiliary material returning mechanism further comprises a driving mechanism for driving the roller support to slide. When the roller support slides to a first set position, the roller extends into an edge of a tray and is used for supporting rubber material. When the roller support slides to a second set position, the roller avoids the rubber material. In the above technical solution, the position of the roller can be adjusted by driving the roller support to extend or retract, so that the roller can be extended to be located within the edge of the tray when material returning is needed, thereby supporting the rubber material to enable the rubber material to fall on the tray during material returning.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this application clearer, the application will now be described in further detail with reference to the accompanying drawings.

[0019] It should be noted that, unless otherwise defined, the technical or scientific terms used in one or more embodiments of this specification should have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms "first," "second," and similar words used in one or more embodiments of this specification do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects.

Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0020] To facilitate understanding of the auxiliary material ejection mechanism provided in this application embodiment, its application scenario is first described. The auxiliary material ejection mechanism provided in this application embodiment is applied in the scenario of tire material feeding. Currently, the tire reel is often not directly below the driven roller of the guide cutter's feeding roller, resulting in the tire material not being ejected to the reel during guide cutter ejection. Therefore, manual intervention is required to complete the ejection, leading to high labor intensity and low work efficiency for workers. Therefore, this application embodiment provides an auxiliary material ejection mechanism to improve the efficiency of ejection. A detailed description is given below with reference to specific drawings and embodiments.

[0021] refer to Figure 1 , Figure 1This diagram illustrates an application scenario of the auxiliary material ejection mechanism 100 provided in this embodiment. The auxiliary material ejection mechanism 100 is applied in a guide cutter, which mainly includes a tray 300 and a conveying device 200. The tray 300 carries the tire material 400, and the tire material carried by the tray 300 can be conveyed by the conveying device 200, i.e., the conveying device 200 is used to convey the tire material 400 carried by the tray 300 to the required workstation. When a material change is required, the conveying device 200 changes its transmission direction, and the tire material 400 on the conveying device 200 is conveyed in the opposite direction to the tray 300. Currently, since the tray 300 is not directly below the conveying device 200, simply changing the transmission direction of the conveying device 200 cannot directly drop the material into the tray 300. Therefore, an auxiliary material ejection mechanism 100 is provided, fixed relative to the support structure 210 of the conveying device 200. When the conveying device 200 ejects material, the auxiliary material ejection mechanism 100 assists in dropping the material into the tray 300. The following is a detailed description with reference to the accompanying drawings and embodiments.

[0022] Please refer to the above. Figure 1 and Figure 2 As shown, Figure 2 This is a schematic diagram of the auxiliary unloading mechanism 100 provided in this application embodiment. The auxiliary unloading mechanism 100 includes a support frame 110, a roller bracket 120, and a roller 130. The support frame 110 serves as a support structure 210 for the roller bracket 120 and the roller 130, and is fixed relative to the support structure 210 of the conveying device 200 to fix the entire auxiliary unloading mechanism 100 in a fixed position relative to the support structure 210 of the conveying device 200. The roller bracket 120 is slidably mounted on the support frame 110 and can slide back and forth relative to the support frame 110. The roller bracket 120 supports the roller 130, which is a component in contact with the tire material 400. When the conveying device 200 unloads the tire material, the roller 130 supports the tire material 400. The structure of each part of the auxiliary unloading mechanism 100 is described in detail below.

[0023] Continue to refer to Figure 1 and Figure 2As shown, the support frame 110 provided in this embodiment of the application is used to support the roller bracket 120. The support frame 110 can be a beam structure or other structure that can provide support. In specific configuration of the support frame 110, it can be fixed to the support structure 210 of the conveying device 200, or the support structure 210 of the conveying device 200 and the support frame 110 can be fixed relative to each other. For example, the support structure 210 of the conveying device 200 and the support frame 110 can be fixed together on a base or other fixed structure. In an optional embodiment, the support frame 110 is fixed to the support structure 210 of the conveying device 200, thereby allowing the auxiliary unloading mechanism 100 to be fixed relative to the support structure 210 of the conveying device 200 and providing stable support.

[0024] For ease of understanding, the two opposite ends of the conveying device 200 are defined as the input end and the output end. The input end is the end where the tire material 400 enters the conveying device 200 during normal conveying, while the output end is the end where the tire material 400 exits the conveying device 200 during normal conveying. When the tire material 400 is being unloaded, it exits the conveying device 200 from the input end.

[0025] In an alternative embodiment, the support frame 110 is fixed to the support structure 210 of the conveying device 200 on the side near the input end. This facilitates the auxiliary unloading mechanism 100 supporting the tire material 400 during unloading.

[0026] Continue to refer to Figure 1 and Figure 2 As shown, the roller bracket 120 provided in this embodiment of the application is used to support the roller 130 and rotatably connected to the roller bracket 120, and is used to contact the tire material 400. It should be understood that the axis around which the roller 130 rotates is perpendicular to the sliding direction of the roller 130, so that the roller 130 can rotate relative to the tire material 400 when the tire material 400 is conveyed by the conveying device 200.

[0027] The roller support 120 is slidably mounted on the support frame 110 and can slide back and forth relative to the support frame 110, so that the roller support 120 can slide back and forth relative to the support structure 210 of the conveying device 200. Figure 1As shown, the roller support 120 is located on one side of the tire material 400 that contacts the conveying device 200. When the roller support 120 slides to a certain position, the roller 130 on the roller support 120 can contact the side of the tire tread that contacts the conveying device 200, thereby supporting the tire material 400 and changing the drop position of the tire material 400. Specifically, the roller support 120 can slide back and forth between a first set position and a second set position. When the roller support 120 slides to the first set position, the roller 130 extends into the edge of the tray 300 and is used to support the rubber material. At this time, the roller 130 is located directly above the tray 300. The auxiliary unloading mechanism 100 can be regarded as an extension structure of the conveying device 200, so that the drop position of the tire material 400 can be located on the tray 300, ensuring that the tire material 400 can fall into the tray 300 for support during unloading. When the roller support 120 slides to the second set position, the roller 130 avoids the rubber material. This state corresponds to the state when the conveying device 200 is normally conveying the tire material 400. When the roller support 120 is in the second set position, the roller 130 does not contact the tire material 400, and the tire material 400 can be directly conveyed to the conveying device 200 through the pallet 300.

[0028] In addition, the auxiliary unloading mechanism 100 provided in this application embodiment also includes a driving mechanism 140, which is used to drive the roller support 120 to slide, specifically to drive the roller support 120 to slide back and forth to meet the needs of the guide cutter.

[0029] As can be seen from the above description, the auxiliary unloading mechanism 100 provided in this application embodiment drives the extension and retraction of the roller bracket 120 through the drive mechanism 140, thereby adjusting the position of the roller 130. When unloading is required, the roller 130 can be extended so that the roller 130 is located within the edge range of the tray 300, thereby supporting the adhesive material so that the adhesive material can fall onto the tray 300 when unloading.

[0030] In an optional embodiment, the auxiliary unloading mechanism 100 provided in this application can also be used to fold the tire material 400 during unloading. (See reference...) Figure 1As shown, when the tire material 400 is placed on the pallet 300, it adopts an S-shaped folding method. Therefore, during unloading, the reciprocating sliding stroke of the roller support 120 matches the folded length of the tire material 400 on the pallet 300, thus folding the tire material 400 into an S-shape during unloading. Specifically, the roller support 120 can also slide to a third preset position, which is located between the first preset position and the second preset position. The first and third preset positions are respectively located at the two ends of the folded tire material 400 on the pallet 300. During unloading, the roller support 120 slides back and forth between the third preset position and the first preset position, thereby folding the tire material 400 onto the pallet 300 during unloading, facilitating the continued feeding of subsequent tire materials 400. When using the above method, the auxiliary unloading mechanism 100 can be implemented in conjunction with automated control. If a sensor and controller are installed on one side of the equipment, the controller controls the drive mechanism 140 and the sliding position and stroke of the roller support 120. Additionally, the sensor detects the position where the tire material 400 falls onto the tray 300, and controls the roller support to slide accordingly based on the position of the tire material 400, so that the tire material 400 folds into an S-shape. It should be understood that the above-described coordination of the sensor, controller, and drive mechanism 140 is a common control method. The controller can be a conventional microcontroller or host computer, and the sensor can be a common position-collecting sensor.

[0031] Continue to refer to Figure 1 and Figure 2 As shown, the support frame 110 provided in this embodiment includes a support beam 112 and two connecting beams 111. The connecting beams 111 are fixed to opposite ends of the support beam 112, forming a U-shaped structure. During installation, the roller bracket 120 is slidably mounted on the support beam 112, the drive mechanism 140 is fixed on the support beam 112, and the connecting beams 111, as connecting structures, are fixedly connected to the support structure 210 of the conveying device 200.

[0032] When this structure is adopted, the support frame 110 is hoisted below the conveying device 200 by the connecting beam 111, so that there is a height difference between the roller support 120 and the conveying device 200, and the sliding of the roller support 120 will not affect the conveying device 200.

[0033] In one feasible embodiment, when the roller support 120 is slidably connected to the support frame 110, a guide sleeve 113 can be provided on the support beam 112. The roller support 120 is slidably assembled within the guide sleeve 113 to provide support for the roller support via the guide sleeve 113. For example, the roller support 120 includes a support frame and a guide shaft 121. The support frame has a U-shaped opening structure, with its opening direction facing away from the drive mechanism 140 (i.e., away from the support frame 110), and the two opposing sidewalls of the support frame are horizontally arranged. During assembly, the guide shaft 121 is slidably assembled within the guide sleeve 113, thereby achieving horizontal sliding (to achieve horizontal sliding). Figure 1 and Figure 2 The placement direction of the auxiliary unloading mechanism 100 is the reference direction.

[0034] When arranging the rollers 130, the rollers 130 are rotatably connected to the support frame. Specifically, the rollers 130 are disposed within the support frame, and the rollers 130 are rotatably connected to two opposite side walls of the support frame. In an optional embodiment, there are multiple rollers 130, and the arrangement direction of the multiple rollers 130 is along the sliding direction of the roller support 120, so that the tire material 400 can be supported by multiple rollers 130 when supporting the tire material 400. For example, when there are multiple rollers 130, the rollers 130 located at the opening of the support frame 122 are partially exposed outside the support frame 122, thereby reducing friction between the support frame 122 and the tire material 400 during unloading, and improving the safety of the tire material 400 during unloading.

[0035] In an alternative embodiment, the guide sleeve 113 may be partially exposed outside the support beam 112. Specifically, the portion of the guide sleeve 113 exposed outside the support beam 112 is located on the side of the support beam 112 away from the bracket frame. That is, the length of the guide sleeve 113 may be greater than the width of the support beam 112, thereby increasing the contact area between the guide sleeve 113 and the guide shaft 121, and thus improving the horizontal support for the roller bracket 120. This ensures that when the roller 130 contacts the tire material 400, the roller 130 can provide sufficient force to change the direction of transmission.

[0036] In one alternative configuration, there are two guide sleeves 113 and two guide shafts 121. When arranged, the two guide sleeves 113 are positioned on opposite sides of the drive mechanism 140, and the guide shafts 121 are also positioned on opposite sides of the drive mechanism 140. With this structure, the drive mechanism 140 is located in the middle, and the two guide sleeves 113 are on either side, thus ensuring the stability of the roller support 120 during sliding and reducing the likelihood of the roller support 120 jamming during drive.

[0037] In one alternative embodiment, the drive mechanism 140 provided in this application can be a drive cylinder, a drive hydraulic cylinder, or a linear motor. Of course, in addition to the specific drive mechanism 140 described above, other linear drive mechanisms 140 can also be applied to the embodiments of this application.

[0038] This application embodiment also provides a guide cutting machine, which includes a conveying mechanism and a tray 300 located at one end of the conveying mechanism; wherein, the conveying device 200 is provided with a feeding driven roller, and the rubber material carried by the tray 300 can be conveyed through the conveying device 200 after passing around the feeding driven roller; It also includes an auxiliary unloading mechanism 100 of any of the above, wherein the support frame 110 is fixed relative to the support structure 210 of the conveying device 200.

[0039] In the above technical solution, the roller support 120 is extended and retracted by the drive mechanism 140, thereby adjusting the position of the roller 130. When it is necessary to unload the material, the roller 130 can be extended so that the roller 130 is located within the edge range of the tray 300, thereby supporting the rubber material so that the rubber material can fall on the tray 300 when unloading.

Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments of this specification should be included within the scope of protection of this disclosure.

[0041] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
