Specific embodiments

[0034] The present utility model will be described below in conjunction with specific embodiments.

[0035] Embodiment 1, as Figures 1 to 4 shown, a manual side guiding device includes a left support frame 11 and a right support frame 12 which are arranged opposite to each other horizontally and at intervals. A left guide wheel frame 21 and a right guide wheel frame 22 are horizontally slidably installed between the left support frame 11 and the right support frame 12. A left lead screw nut 31 is screwed and fixed to the lower end of the left guide wheel frame 21, and a right lead screw nut 32 is screwed and fixed to the lower end of the right guide wheel frame 22.

[0036] Among them, as Figures 1 to 4 shown, a vertically arranged left side guide wheel 41 is installed at the upper end of the left guide wheel frame 21, and a vertically arranged right side guide wheel 42 is installed at the upper end of the right guide wheel frame 22.

[0037] Furthermore, as Figure 1 and Figure 2As shown, the manual side guide device further includes a first driving lead screw 51 and a second driving lead screw 52 that horizontally extend along the left-right direction. The left end of the first driving lead screw 51 is installed on the left support frame 11 through a left bearing block 61. The first driving lead screw 51 cooperates with the left lead screw nut 31 to jointly form a ball screw pair. The right end of the first driving lead screw 51 is provided with a first screw shaft portion 511 that horizontally extends to the right and is coaxially integrated with the first driving lead screw 51.

[0038] Furthermore, as Figure 1 and Figure 2 shown, the second driving lead screw 52 cooperates with the right lead screw nut 32 to jointly form a ball screw pair. An axially penetrating second screw shaft hole 521 is provided in the core of the second driving lead screw 52. The second driving lead screw 52 is rotationally sleeved around the periphery of the first screw shaft portion 511 through the second screw shaft hole 521. The right end of the second driving lead screw 52 is installed on the right support frame 12 through a right bearing block 62.

[0039] In addition, as Figure 2 and Figure 3 shown, the upper parts of the left guide wheel frame 21 and the right guide wheel frame 22 are respectively provided with a long hole 23 that vertically penetrates and extends along the left-right direction, a left internal thread hole 24 that opens to the left and whose right end communicates with the long hole 23, and a right internal thread hole 25 that opens to the right and whose left end communicates with the long hole 23. A left fine adjustment screw 71 is screwed in the left internal thread hole 24, and a right fine adjustment screw 72 is screwed in the right internal thread hole 25. The lower ends of the wheel shafts of the left side guide wheel 41 and the right side guide wheel 42 are respectively inserted into the long holes 23 on the corresponding sides, and the lower ends of each wheel shaft are respectively clamped and limited between the left fine adjustment screw 71 and the right fine adjustment screw 72 on the corresponding side.

[0040] When the manual side guide device in the first embodiment works, when the first driving lead screw 51 is manually rotated, the ball screw pair composed of the first driving lead screw 51 and the left lead screw nut 31 drives the left guide wheel frame 21 to move left and right, thereby realizing the left and right displacement adjustment of the left side guide wheel 41. When the second driving lead screw 52 is manually rotated, the ball screw pair composed of the second driving lead screw 52 and the right lead screw nut 32 drives the right guide wheel frame 22 to move left and right, thereby realizing the left and right displacement adjustment of the right side guide wheel 42. The left side guide wheel 41 and the right side guide wheel 42 in the first embodiment are independently driven by the corresponding ball screw pairs, that is, the left side guide wheel 41 and the right side guide wheel 42 can realize independent movement to adjust the position. Compared with the synchronous linkage adjustment structure of the side guide wheels on the left and right sides in the prior art, the manual side guide device in the first embodiment has better adjustability.

[0041] In addition, the first driving lead screw 51 and the second driving lead screw 52 in the first embodiment are assembled and connected by sleeving the first lead screw shaft portion 511 with the second lead screw hole 521. This structural design has the advantage of good structural compactness.

[0042] It should be emphasized that the left side guide wheel 41 and the right side guide wheel 42 in the first embodiment can be roughly adjusted in position through the corresponding ball screw pair. When fine adjustment of the positions of the left side guide wheel 41 and the right side guide wheel 42 is required, only the positions of the left fine adjustment screw 71 and the right fine adjustment screw 72 need to be adjusted to move the wheel shafts of the side guide wheels left and right within the long holes 23. The specific fine adjustment process is as follows: When it is necessary to adjust the position of the left side guide wheel 41 or the right side guide wheel 42 to the left, screw out the left fine adjustment screw 71 and screw in the right fine adjustment screw 72; when it is necessary to adjust the position of the left side guide wheel 41 or the right side guide wheel 42 to the right, screw out the right fine adjustment screw 72 and screw in the left fine adjustment screw 71. The left guide wheel frame 21 and the right guide wheel frame 22 in the first embodiment can respectively fine-adjust the positions of the left side guide wheel 41 and the right side guide wheel 42 through the fine adjustment structure composed of the left fine adjustment screw 71 and the right fine adjustment screw 72 to improve the position adjustment accuracy.

[0043] It should be further emphasized that when fine-adjusting the positions of the left side guide wheel 41 and the right side guide wheel 42, the lower end portions of the wheel shafts of the left side guide wheel 41 and the right side guide wheel 42 respectively move left and right along the corresponding long holes 23. The long holes 23 can finely guide the left side guide wheel 41 and the right side guide wheel 42 to improve the accuracy and convenience during fine adjustment.

[0044] Based on the above situation, through the above structural design, the manual side guide position device in the first embodiment has the advantages of novel structural design, good adjustability, and high adjustment accuracy.

[0045] Embodiment 2, as Figure 1 and Figure 2 shown, the difference between the second embodiment and the first embodiment is that the right end portion of the first lead screw shaft portion 511 protrudes from the right end opening of the second lead screw hole 521, and a small handwheel 81 is fixedly installed at the right end portion of the first lead screw shaft portion 511.

[0046] Among them, a large handwheel 82 is fixedly installed at the right end portion of the second driving lead screw 52, and the small handwheel 81 and the large handwheel 82 are respectively located on the right end side of the right support frame 12.

[0047] When roughly adjusting the positions of the left side guide wheel 41 and the right side guide wheel 42, the staff can drive the corresponding first driving lead screw 51 and second driving lead screw 52 to rotate through the small handwheel 81 and the large handwheel 82.

[0048] It should be noted that since the small handwheel 81 and the large handwheel 82 are located on the same side, when adjusting the positions of the left side guide wheel 41 and the right side guide wheel 42, the staff can perform the adjustment operation as long as they are on one side, which is very convenient to use.

[0049] Embodiment 3, as Figure 1 and Figure 2 shown, the difference between this Embodiment 3 and Embodiment 1 is that: the left end face of the second driving lead screw 52 is connected to the first driving lead screw 51 through an end face bearing 91.

[0050] Wherein, the inner wall of the second lead screw shaft hole 521 and the outer circumferential surface of the first lead screw shaft portion 511 are arranged at intervals, and two bushings 92 arranged at axial intervals are installed between the inner wall of the second lead screw shaft hole 521 and the first lead screw shaft portion 511.

[0051] The inner wall of the second lead screw shaft hole 521 is spaced from the outer circumferential surface of the first lead screw shaft portion 511 through the bushing 92, and the left end face of the second driving lead screw 52 is connected to the first driving lead screw 51 through the end face bearing 91. This connection structure design can effectively reduce the contact area between the first driving lead screw 51 and the second driving lead screw 52. On the one hand, it can reduce the processing cost, and on the other hand, it can effectively reduce the friction force between the two.

[0052] Embodiment 4, as Figure 3 and Figure 4 shown, the difference between this Embodiment 4 and Embodiment 1 is that, to ensure the smooth left and right movement of the left side guide wheel frame 21 and the right side guide wheel frame 22, the following guiding structure design can be adopted in this Embodiment 4. Specifically: at least two guide rods 101 arranged at intervals front and back are installed between the left support frame 11 and the right support frame 12. The left end parts and right end parts of the respective guide rods 101 are respectively connected to the left support frame 11 and the right support frame 12 on the corresponding side; the left side guide wheel frame 21 is respectively provided with left side guide sleeves 102 corresponding to the respective guide rods 101, and the respective left side guide sleeves 102 are respectively matched with the corresponding guide rods 101; the right side guide wheel frame 22 is respectively provided with right side guide sleeves 103 corresponding to the respective guide rods 101, and the respective right side guide sleeves 103 are respectively matched with the corresponding guide rods 101.

[0053] Embodiment 5, as Figure 1 and Figure 4 shown, the difference between this Embodiment 5 and Embodiment 1 is that: a conveying roller group is installed between the left support frame 11 and the right support frame 12, and the conveying roller group is located above the left side guide wheel frame 21 and the right side guide wheel frame 22.

[0054] Among them, the conveying roller group includes a number of transverse conveying rollers 110 that are arranged at intervals from front to back and horizontally extend in the left-right direction respectively. The left end and the right end of each transverse conveying roller 110 are respectively connected to the left support frame 11 and the right support frame 12 on the corresponding side.

[0055] During the process of material conveying, the material is supported and moved by each transverse conveying roller 110 of the conveying roller group, and the left side guide wheel 41 and the right side guide wheel 42 position the corresponding left and right edges of the material to ensure accurate conveying of the material.

[0056] The above content is only the preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
