[0002] Brushes are tools that people use frequently in their daily lives. A brush blank is the blank before the bristles are attached. In the actual production process, a bristle attaching machine is usually used to attach bristles to the blank, and then the brush is obtained after trimming.

[0003] In actual tufting production, some brush blanks are placed onto the tufting machine manually, which is inefficient and does not meet the requirements of fully automated production. Others use a horizontal conveyor table for conveying, during which a robotic arm picks up the brush blanks from the conveyor belt and moves them to the tufting machine to achieve automatic feeding. However, the horizontal conveyor table occupies a large space, resulting in poor space utilization. Utility Model Content

[0032] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.

[0033] A type of blank transport mechanism, such as Figures 1-3As shown, the device includes a frame 1 and a housing 2. The frame 1 is located inside the housing 2. A conveyor belt 3 for circulating transport is installed on the frame 1. The conveyor belt 3 is connected end to end to form a closed loop. At the same time, a conveyor wheel 4 is installed on the frame 1 to guide the conveyor belt 3 to bend horizontally multiple times. After bending, the conveyor belt 3 has multiple horizontal parts 5, which are distributed vertically. Placement plates 6 for placing brush blanks are installed on the conveyor belt 3. The placement plates 6 are horizontally arranged and are distributed at intervals along the conveying direction of the conveyor belt 3. In actual use, multiple brush blanks can be placed on each placement plate 6, and then the placement plates 6 are automatically transported by the conveyor belt 3.

[0034] like Figures 2-4 As shown, a shaft 7 is fixedly installed at one end of the placement plate 6, and the other end of the placement plate 6 is rotatably connected to the conveyor belt 3 through the shaft 7. At the same time, a limiting component is provided on the machine body to keep the placement plate 6 in a horizontal state. With the help of the limiting component, the placement plate 6 can always be kept in a horizontal state during the conveying process, avoiding the placement plate 6 from tilting when the conveyor belt 3 turns, which would cause the brush blanks to fall off. The bent and distributed conveyor belt 3 structure can set more placement plates 6 for placing brush blanks in a limited space, effectively improving space utilization, realizing automatic conveying of brush blanks, effectively improving production efficiency, and allowing workers to do other work after placing all the brush blanks, thus improving labor utilization.

[0035] like Figure 3 and Figure 4 As shown, the limiting component includes an auxiliary belt 8 and a limiting plate 9. The auxiliary belt 8 is also bent and its shape is consistent with and matches that of the conveyor belt 3. The auxiliary belt 8 is conveyed synchronously with the conveyor belt 3. The auxiliary belt 8 is circulated and is set on the frame 1. The auxiliary belt 8 is set parallel to the conveyor belt 3 front and back. The limiting plate 9 and the placement plate 6 are set one-to-one. A connecting shaft 10 is fixedly set on the limiting plate 9. One side of the limiting plate 9 is rotatably connected to the auxiliary belt 8 by means of the connecting shaft 10. The shaft 7 on the placement plate 6 passes through the conveyor belt 3. The end of the shaft 7 is fixed to the side of the limiting plate 9 facing away from the connecting shaft 10. The axis of the shaft 7 is not collinear with the axis of the connecting shaft 10. In this embodiment, the axis of the shaft 7 is higher than the axis of the connecting shaft 10. This can limit the rotation of the placement plate 6 and the shaft 7, so that the placement plate 6 can always be kept in a horizontal state during the conveying process, realizing the stable placement of the brush blank, providing the stability of the conveying, and improving the space utilization.

[0036] like Figures 2-4As shown, in this embodiment, both the conveyor belt 3 and the auxiliary belt 8 are made of chains. A through hole 11 is provided at the joint hinge of the chain. The shaft 7 on the placement plate 6 passes through the through hole 11 and is adapted to it to achieve relative rotation. The connecting shaft 10 on the limiting plate 9 passes through the through hole 11 and is adapted to it to achieve relative rotation. The structure of using chains makes it easier to rotate and install the shaft 7 and the connecting shaft 10, and does not affect the automatic conveying achieved by multiple horizontal bends of the chain, while maximizing the space utilization rate.

[0037] like Figures 5-8 As shown, an auxiliary wheel 12 is provided on the frame 1 to guide the auxiliary belt 8 through multiple bends. In this embodiment, both the conveyor wheel 4 and the auxiliary wheel 12 are sprockets. The auxiliary wheel 12 is arranged in a one-to-one correspondence with the conveyor wheel 4. The auxiliary wheel 12 is rotatably connected to the frame 1. At the same time, a mounting plate 13 is provided on the frame 1 and is detachably connected to it. The conveyor wheel 4 is rotatably connected to the mounting plate 13. The conveyor wheel 4 is located at each bend of the conveyor belt 3, and the auxiliary wheel 12 is located at each bend of the auxiliary belt 8. In addition, a drive source is provided on the frame 1 to drive the conveyor belt 3 and the auxiliary belt 8. In this embodiment, the drive source includes a drive motor 14 and a reducer 15. The input end of the reducer 15 is connected to the output end of the drive motor 14. In this embodiment, one of the corresponding conveyor wheel 4 and auxiliary wheel 12 is a drive wheel. The output end of the reducer 15 is rotatably connected to the mounting plate 13. A bearing 16 is provided on the mounting plate 13 to support the output end of the reducer 15.

[0038] like Figure 8 and Figure 9 As shown, a drive gear 17 is provided at the output end of the reducer 15, and driven gears 18 are provided on the conveyor wheel 4 and the auxiliary wheel 12. The axial thickness of the drive gear 17 is greater than the sum of the axial thicknesses of the two driven gears 18. The driven gears 18 on the conveyor wheel 4 and the auxiliary wheel 12 mesh on the same side of the drive gear 17. In this way, only one drive source is needed to drive the conveyor wheel 4 and the auxiliary wheel 12 to rotate synchronously, which effectively simplifies the structure, makes the overall structure more compact, and saves the drive source to achieve the purpose of reducing costs.

[0039] like Figure 1 As shown, in actual use, a placement groove adapted to the shape of the brush blank can be opened on the top of the placement plate 6. The stability of the brush blank placement is further improved by the cooperation between the placement groove and the brush blank. In addition, there are pre-installation holes on the end face of the placement plate 6 away from the conveyor belt 3. The pre-installation holes can be used to determine whether to install the support bearing 19 according to actual needs. When the length of the brush blank is relatively long, resulting in a longer length of the placement plate 6, the support bearing 19 can be installed on the pre-installation holes. The support bearing 19 can provide auxiliary support for the free end of the placement plate 6, reducing the impact on the horizontality of the placement plate 6 due to its long length. This facilitates the subsequent marking of the brush blank on the placement plate 6 and also facilitates the precise gripping of the robot arm.

[0040] like Figure 1 As shown, there is an opening 20 at the front front of the housing 2 corresponding to the area of ​​the conveyor belt 3. The operator can place the brush blank at the opening 20. Safety light curtains 21 are set on the opposite sides of the opening 20 on the housing 2. The design of the safety light curtains 21 can play a safety protection role. If the operator accidentally puts his hand in during operation, the conveyor can be stopped in time to avoid injury to the operator and improve the safety of use.

[0041] like Figure 4 and Figure 5 As shown, auxiliary support bearings 22 are provided at both ends of the shaft 7 of the placement plate 6. The two auxiliary support bearings 22 are located between the limiting plate 9 and the conveyor belt 3, and between the placement plate 6 and the conveyor belt 3, respectively. In addition, support plates 23 are fixedly provided on the frame 1. The support plates 23 are spaced apart, and a moving groove 24 is formed between adjacent support plates 23 to match the conveyor belt 3 and allow it to move and be conveyed. The upper and lower sides of the auxiliary support bearings 22 abut against the support plates 23, respectively. In this way, the support plates 23 and auxiliary support bearings 22 can provide good support for the conveyor belt 3, improve the conveying stability of the conveyor belt 3, prevent the conveyor belt 3 from sagging due to gravity at the placement plate 6, and ensure that the conveyor belt 3 moves and is conveyed stably along the moving groove 24.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
