Detailed Implementation

[0034] The present invention will now be described in conjunction with specific embodiments.

[0035] Example 1, as Figures 1 to 4 As shown, a pressing and feeding assembly includes a frame 1, a fixed bracket 2 is fastened to the frame 1, and a first synchronous belt assembly 3 is mounted on the fixed bracket 2. The first synchronous belt assembly 3 includes a first driving synchronous belt pulley 31, a first driven synchronous belt pulley 32, and a first feeding synchronous belt 33 wound between the first driving synchronous belt pulley 31 and the first driven synchronous belt pulley 32.

[0036] Among them, such as Figures 1 to 4 As shown, the pressing and feeding assembly also includes a movable bracket 4, which is equipped with a second synchronous belt assembly 5 that moves synchronously with the first synchronous belt assembly 3. The second synchronous belt assembly 5 includes a second driving synchronous belt pulley 51, a second driven synchronous belt pulley 52, and a second feeding synchronous belt 53 that is wound between the second driving synchronous belt pulley 51 and the second driven synchronous belt pulley 52.

[0037] It should be noted that, as Figures 1 to 4 As shown, the movable bracket 4 is located directly above the fixed bracket 2, and the movable bracket 4 and the fixed bracket 2 are arranged at intervals.

[0038] Furthermore, such as Figure 1 and Figure 2 As shown, the frame 1 is securely mounted with an adjusting bracket 61 located above the movable bracket 4. The movable bracket 4 is rotatably mounted with a vertically arranged adjusting screw 62 via bearings. The upper end of the adjusting screw 62 extends above the adjusting bracket 61. The adjusting bracket 61 is screwed with a screw nut 63 corresponding to the adjusting screw 62, and the adjusting screw 62 and the screw nut 63 cooperate. To facilitate the operator's rotation operation of the adjusting screw 62, a drive handwheel 64 located above the adjusting bracket 61 is securely mounted on the upper end of the adjusting screw 62, meaning that the adjustment screw 62 can be rotated simply by driving the handwheel 64.

[0039] Furthermore, such as Figure 4 As shown, the conveying surfaces of the first feeding synchronous belt 33 and the second feeding synchronous belt 53 are respectively covered with a soft rubber layer 7.

[0040] It needs to be explained that, such as Figures 1 to 4 As shown, the first synchronous belt assembly 3 further includes a first driving shaft 34 and a first driven shaft 35. The first driving shaft 34 and the first driven shaft 35 are rotatably mounted on the fixed bracket 2 via bearings. The first driving synchronous pulley 31 is mounted on the first driving shaft 34, and the first driven synchronous pulley 32 is mounted on the first driven shaft 35. The second synchronous belt assembly 5 further includes a second driving shaft 54 ​​and a second driven shaft 55. The second driving shaft 54 ​​and the second driven shaft 55 are rotatably mounted on the movable bracket 4 via bearings. The second driving synchronous pulley 51 is mounted on the second driving shaft 54, and the second driven synchronous pulley 52 is mounted on the second driven shaft 55. The frame 1 is equipped with a reduction drive motor 81. The power output shaft of the reduction drive motor 81 is driven and connected to the first driving shaft 34 and the second driving shaft 54 ​​respectively. During operation, the reduction drive motor 81 drives the first driving shaft 34 and the second driving shaft to rotate synchronously, thereby causing the first synchronous belt assembly 3 and the second synchronous belt assembly 5 to move synchronously.

[0041] During the feeding of workpiece products using the pressing and feeding assembly of this embodiment, the workpiece product is placed into the gap between the first feeding synchronous belt 33 and the second feeding synchronous belt 53. The first feeding synchronous belt 33 contacts and presses against the workpiece product through the soft rubber layer 7, and the second feeding synchronous belt 53 also contacts and presses against the workpiece product through the soft rubber layer 7. That is, the workpiece product is pressed by the first feeding synchronous belt 33 and the second feeding synchronous belt 53. During the synchronous movement of the first feeding synchronous belt 33 and the second feeding synchronous belt 53, the workpiece product moves synchronously with the first feeding synchronous belt 33 and the second feeding synchronous belt 53, thereby realizing the workpiece product feeding operation.

[0042] It should be emphasized that in this embodiment, the first feeding synchronous belt 33 and the second feeding synchronous belt 53 of the pressing and feeding assembly contact and press the workpiece through the soft rubber layer 7. The clamping force of the soft rubber layer 7 makes the workpiece move synchronously with the first feeding synchronous belt 33 and the second feeding synchronous belt 53. The soft rubber layer 7 can effectively prevent the surface of the workpiece from being scratched.

[0043] Since the workpiece is fed and moved by the clamping force of the soft rubber layer 7, during operation, the operator can adjust the position of the screw nut 63 by rotating the screw 62, thereby adjusting the position of the movable bracket 4 and the second synchronous belt assembly 5, and adjusting the gap between the first feeding synchronous belt 33 and the second feeding synchronous belt 53 to achieve adaptive adjustment of the clamping force.

[0044] In summary, the clamping and feeding assembly of this embodiment has the advantages of novel structural design, convenient and quick adjustment of clamping force, and can effectively prevent the surface of the workpiece from being scratched during the conveying process.

[0045] Example 2, as Figures 1 to 3 As shown, the difference between this embodiment 2 and embodiment 1 is that the power output shaft of the speed reduction drive motor 81 is connected to the first active rotating shaft 34 through the coupling 82.

[0046] The frame 1 is also equipped with an auxiliary support 83. The upper end of the auxiliary support 83 is rotatably mounted with an auxiliary rotating shaft 84 via a bearing. The first active rotating shaft 34 is driven to connect with the auxiliary rotating shaft 84 via a transmission pair 85. The auxiliary rotating shaft 84 is also driven to connect with the second active rotating shaft 54 ​​via a transmission pair 85.

[0047] It should be explained that the transmission pair 85 in this embodiment 2 is a gear transmission pair 85 or a belt transmission pair 85.

[0048] During the process of the geared drive motor 81 driving the first synchronous belt assembly 3 and the second synchronous belt assembly 5 to move synchronously, the geared drive motor 81 starts, and the power output shaft of the geared drive motor 81 drives the first active rotating shaft 34 to rotate through the coupling 82. The first active rotating shaft 34 drives the auxiliary rotating shaft 84 to rotate through the transmission pair 85. The rotating auxiliary rotating shaft 84 then drives the second active rotating shaft 54 ​​to rotate through another transmission pair 85, thereby making the first active rotating shaft 34 and the second active rotating shaft 54 ​​rotate synchronously, so as to realize the synchronous operation of the first synchronous belt assembly 3 and the second synchronous belt assembly 5, and make the first feeding synchronous belt 33 and the second feeding synchronous belt 53 move synchronously, thereby ensuring the stability of workpiece feeding.

[0049] Example 3, as Figure 1 and Figure 2 As shown, the difference between this embodiment 3 and embodiment 1 is that: the movable bracket 4 is provided with an adjustment drive plate 65 arranged horizontally, the adjustment screw 62 is rotatably mounted on the adjustment drive plate 65 through a bearing, and a guide pair is installed between the adjustment drive plate 65 and the adjustment bracket 61.

[0050] Specifically, the guide pair includes several guide posts 66 that are respectively fastened to the adjustment drive plate 65 and arranged vertically. The adjustment bracket 61 is fastened to each guide post 66 with a guide sleeve 67, and each guide post 66 is inserted into the center hole of the corresponding guide sleeve 67.

[0051] During the process of adjusting the movable bracket 4 by driving the adjustment drive structure composed of the adjusting screw 62 and the screw nut 63 to move up and down, the guide pair structure composed of the guide post 66 and the guide sleeve 67 can ensure that the movable bracket 4 moves up and down stably, thereby ensuring the accuracy of the clamping force adjustment.

[0052] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation method and application scope based on the idea of ​​this utility model. The content of this specification should not be construed as a limitation of this utility model.
