Description

Technical Field

[0001] This utility model relates to the technical field of conveyor belt mechanisms, and in particular to material conveying mechanisms. Background Technology

[0002] In the preparation of prepregs, the raw materials are generally supplied in roll form, and then slit and cut to obtain prepregs of corresponding specifications to meet customer requirements. Currently, the cutting of these prepregs is done using a Caiying cutting machine. Typically, when cutting roll prepregs, the cutting area needs to be heated first, and then cut using a cross-cutting blade and / or longitudinal cutter. However, the existing cutting machines operate continuously from loading to unloading. When using the cross-cutting blade, the prepreg will momentarily pause. If feeding continues during this pause, a section of prepreg may slightly stack, resulting in uneven heating.

[0003] The utility model application with application number CN202220486537.3 discloses a feeding mechanism for a cutting machine, including a first frame and a second frame arranged in parallel with each other, and a feeding assembly and a rewinding assembly located between the first frame and the second frame; the feeding assembly includes a feeding air shaft, a feeding shaft, a first feeding traction shaft and a second feeding traction shaft; a first buffer assembly is provided between the first feeding traction shaft and the second feeding traction shaft; the rewinding assembly includes a guide shaft, a pressure roller used in conjunction with the guide shaft, and a discharge air shaft, and a second buffer assembly is provided on one side of the feed end of the guide shaft.

[0004] Because the material belt is prone to loosening during conveying, it may slip and affect the cutting accuracy when it reaches the cutting position. Utility Model Content

[0005] The purpose of this invention is to provide a material conveying mechanism that addresses the shortcomings of existing technologies.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A material conveying mechanism includes a conveyor frame, which is provided with a front conveyor, a middle conveyor and a rear conveyor. The front conveyor includes a first front conveyor roller, a second front conveyor roller, a front active conveyor roller and a front conveyor belt nested between the first front conveyor roller, the second front conveyor roller and the front active conveyor roller. A front tension adjusting member is provided on the outside of the front conveyor belt to adjust the tension of the front conveyor belt.

[0008] The middle conveyor includes a middle conveyor roller capable of longitudinal movement; the rear conveyor includes a first rear conveyor roller, a rear active conveyor roller, and a rear conveyor belt nested between the first rear conveyor roller and the rear active conveyor roller.

[0009] The first front conveyor roller, the second front conveyor roller, and the first rear conveyor roller are arranged side by side, and the material belt passes sequentially through the top of the first front conveyor roller, the top of the second front conveyor roller, the bottom of the middle conveyor roller, and the top of the first rear conveyor roller.

[0010] Furthermore, the front conveyor also includes a front support platform located between the first front conveyor roller and the second front conveyor roller, and a strip support plate for supporting the strip to be cut is mounted on the top of the front support platform.

[0011] Furthermore: a front support seat is installed at the bottom of the support platform, and a first adjustment groove is formed along the length of the front support seat. The front support seat is installed on the conveyor frame with adjustable height through the first adjustment groove. Outwardly bent guide plates are formed at both ends of the material belt support plate.

[0012] Furthermore: the front tension adjustment component includes an inclined tension adjustment seat, a front tension wheel that rolls with the front conveyor belt at the outer end of the tension adjustment seat, and a second adjustment groove formed along the length direction of the tension adjustment seat. The tension adjustment seat is installed in the conveyor frame in an adjustable position through the second adjustment groove.

[0013] Furthermore, there are two tension adjustment seats, which are arranged symmetrically on both sides of the front conveyor belt.

[0014] Furthermore, the central conveyor also includes a longitudinally arranged lifting drive, the drive end of which is equipped with a roller mounting seat, and the end of the central conveyor roller is mounted on the roller mounting seat.

[0015] Furthermore, the central conveyor also includes a longitudinally arranged linear guide rail, on which a linear sliding seat is slidably mounted along the length direction, and the linear sliding seat is connected to the roller mounting seat.

[0016] Furthermore: the lifting drive component is a lifting cylinder, which is arranged parallel to the linear guide rail.

[0017] Furthermore, a belt pressing assembly is provided above the second front conveyor roller and the first rear conveyor roller. The belt pressing assembly includes a movable seat that can move radially along the second front conveyor roller, and the movable seat is equipped with a belt pressing roller that contacts the belt of the second front conveyor roller.

[0018] The beneficial effects of this utility model are as follows: the conveyor belt passes sequentially through the top of the first front conveyor roller, the top of the second front conveyor roller, the bottom of the middle conveyor roller, and the top of the first rear conveyor roller. When passing the middle conveyor roller, if the conveyor belt becomes loose, the middle conveyor roller descends to hold the conveyor belt in place, increasing tension and preventing the conveyor belt from becoming loose and causing a decrease in conveying efficiency; when the tension of the conveyor belt is too high, the middle conveyor roller rises to reduce the tension and prevent the conveyor belt from becoming too tight and breaking.

[0034] The present invention will now be described in detail with reference to the accompanying drawings.

[0035] like Figure 1-4 As shown, the material conveying mechanism includes a conveying frame, which is provided with a front conveying component 1, a middle conveying component 2 and a rear conveying component 3. The front conveying component 1 includes a first front conveying roller 11, a second front conveying roller 12, a front active conveying roller 13 and a front conveying belt 192 nested between the first front conveying roller 11, the second front conveying roller 12 and the front active conveying roller 13. A front tension adjusting component is provided on the outside of the front conveying belt 192 to adjust the tension of the front conveying belt 192.

[0036] The central conveyor 2 includes a central conveyor roller 21 that can move longitudinally;

[0037] The rear conveyor 3 includes a first rear conveyor roller 31, a rear active conveyor roller 32, and a rear conveyor belt 37 nested between the first rear conveyor roller 31 and the rear active conveyor roller 32.

[0038] The first front conveyor roller 11, the second front conveyor roller 12, and the first rear conveyor roller 31 are arranged side by side.

[0039] The conveyor belt 10 passes sequentially through the top of the first front conveyor roller 11, the top of the second front conveyor roller 12, the bottom of the middle conveyor roller 21, and the top of the first rear conveyor roller 31. When passing the middle conveyor roller 21, if the conveyor belt 10 becomes loose, the middle conveyor roller 21 descends to pull the conveyor belt 10 back up, increasing the tension and preventing the conveyor belt 10 from becoming loose and causing a decrease in conveying efficiency. When the tension of the conveyor belt 10 is too high, the middle conveyor roller 21 rises to reduce the tension and prevent the conveyor belt 10 from becoming too tight and breaking.

[0040] Specifically, the front conveyor 1 also includes a front support platform located between the first front conveyor roller 11 and the second front conveyor roller 12. A material belt support plate 15 is installed on the top of the front support platform to support the top of the front conveyor belt 192. The material belt support plate 15 can support the material belt that needs to be cut, prevent the material belt from denting when it moves forward, and ensure support for the material belt 10.

[0041] A front support seat 14 is installed at the bottom of the support platform. The front support seat 14 has a first adjusting groove 16 formed along its length. The front support seat 14 is installed on the conveyor frame with adjustable height through the first adjusting groove 16. The material belt support plate 15 has outwardly bent guide plates 191 formed at both ends. The guide plates 191 play a guiding role, which facilitates the material belt to rub against the material belt support plate 15. The height of the front support seat 14 can be adjusted by cooperating with the conveyor frame through the first adjusting groove 16, thereby adjusting the height of the material belt support.

[0042] The front tension adjustment component includes an inclined tension adjustment seat 17. A front tensioning wheel 18 that rolls with the front conveyor belt 192 is installed at the outer end of the tension adjustment seat 17. The tension adjustment seat 17 has a second adjustment groove 19 formed along its length. The tension adjustment seat 17 is installed in an adjustable position on the conveyor frame through the second adjustment groove 19. When the tension of the front conveyor belt 192 does not meet the current conveying requirements, the position of the tension adjustment seat 17 can be adjusted to adjust the pressure between the front tensioning wheel 18 and the front conveyor belt 192, so that the front conveyor belt 192 can convey the material belt 10 more stably and prevent the material belt 10 from stopping.

[0043] Preferably, there are two tension adjustment seats 17, which are arranged symmetrically on both sides of the front conveyor belt 192. The two tension adjustment seats 17 move simultaneously, and the tension of the front conveyor belt 192 can be adjusted without the tension adjustment seat 17 having a large movement path, which makes the adjustment more efficient.

[0044] Furthermore, the central conveyor 2 also includes a longitudinally arranged lifting drive. The driving end of the lifting drive is equipped with a roller mounting seat 22, and the end of the central conveyor roller 21 is mounted on the roller mounting seat 22. When the material belt 10 passes through the central conveyor roller 21, if the material belt 10 becomes loose, the central conveyor roller 21 descends, which can pull the material belt 10, increase the tension, and prevent the material belt 10 from becoming loose and causing a decrease in conveying efficiency. When the tension of the material belt 10 during conveying is too large, the central conveyor roller 21 rises, thereby reducing the tension and preventing the material belt 10 from becoming too tight and breaking.

[0045] Preferably, the lifting drive is a lifting cylinder 23. Under the drive of the lifting cylinder 23, the middle conveyor roller 21 installed on the roller mounting seat 22 can be raised and lowered, so that the tension of the material belt 10 passing through the middle conveyor roller 21 can be adjusted to ensure that the material belt 10 is conveyed forward stably and smoothly.

[0046] Furthermore, a linear guide rail 24 is provided on the side of the guide rod. A linear sliding seat 25 is slidably installed on the linear guide rail 24 along its length. The linear sliding seat 25 is connected to the roller mounting seat 22. When the roller mounting seat 22 moves up and down, the linear sliding seat 25 connected to the roller mounting seat 22 slides along the linear guide rail 24, further ensuring its lifting stability. When the middle conveyor roller 21 moves up and down, it ensures the lateral position of the middle conveyor roller 21 and prevents lateral deviation.

[0047] A belt pressing assembly 33 is provided above the second front conveyor roller 12 and the first rear conveyor roller 31. The belt pressing assembly 33 includes a movable seat 34 that can move radially along the second front conveyor roller 12. The movable seat 34 is equipped with a belt pressing roller 35 that contacts the material belt of the second front conveyor roller 12.

[0048] The pressing assembly 33 also includes a pressing cylinder 36 arranged radially along the second front conveyor roller 12, the drive end of the pressing cylinder 36 being connected to the movable seat 35.

[0049] When the conveying of the material belt 10 needs to be paused, the movable seat 34, driven by the pressure cylinder 36, approaches the second front conveyor roller 12. The pressure roller 35 of the movable seat 34 comes into frictional contact with the material belt, which can stop the second front conveyor roller 12, thus halting its rotation. At this time, the material belt 10 will not continue to move forward, preventing further increases in belt breakage losses.

[0050] Similarly, the pressing assembly 33 of the first rear conveyor roller 31 has the same structure as the pressing assembly 33 of the second front conveyor roller 12, and the specific structure will not be described in detail here.

[0051] In addition, the pressing assembly 33 can adjust the height according to the thickness of the material belt, so that the material belt will not lift up when passing through the front conveyor 1, the middle conveyor 2, and the rear conveyor 3, ensuring that the material belt passes through evenly and ensuring the quality of subsequent cutting.

[0052] In summary, this utility model possesses the aforementioned excellent characteristics, enabling it to achieve unprecedented efficiency in use and thus become a highly practical product.

[0053] 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.
