[0034] The utility model will be described in further detail below in combination with the drawings and examples. It can be understood that the specific examples described here are only used to explain the utility model, and not to limit the utility model. In addition, it should be noted that, in order to facilitate the description, only the part related to the utility model is shown in the drawings, not all structures.

In addition, the terms "first", "second" are only used to distinguish in description, and have no special meaning.

[0038] In combination withFigure 1 , Figure 2 , Figure 3 As shown, this embodiment provides a conveying device, which includes a conveying assembly 1, a conveying screw 3, and a screw adjusting assembly 4.

[0039] Combination Figure 1 , Figure 3 As shown, the conveying assembly 1 is capable of conveying material 2 along a first direction X1 (the first direction X1 is the material conveying direction), and the material 2 is, for example, a bottle-shaped material such as a glass bottle or a PET bottle. For example, as shown... Figure 2 As shown, the conveying assembly 1 includes a base 11, a chain guide rail 12, and a conveying chain 13. The base 11 extends along the conveying direction and has a mounting opening 111 at its top. The chain guide rail 12 is mounted to this mounting opening 111. In this embodiment, the chain guide rail 12 is mounted to the mounting opening 111 by a snap-fit ​​method. In other embodiments, the chain guide rail 12 can also be mounted to the mounting opening by bolts (for example, by the cooperation of a guide rail pressure plate and a bolt assembly on the upper surface of the chain guide rail 12, pressing the chain guide rail 12 tightly against the mounting opening 11). The conveying chain 13 is disposed on the chain guide rail 12. This conveying chain 13 is a conveying chain 13 formed by combining multiple chain plates or chain links (e.g., a keel chain). There is a gap between adjacent chain links or chain plates in this type of conveying chain 13, allowing the conveying chain 13 to support small-angle steering.

[0040] In the aforementioned conveying device, by configuring the conveying assembly as a base 11, a chain guide rail 12, and a conveying chain 13, the base 11 can provide installation space for other mechanical structures (i.e., with...). Figure 3 Taking the shown perspective as an example, a protective assembly 5 is installed on the left side of the base 11, and a screw adjustment assembly 4 is installed on the right side of the base 11, making the overall structure of the conveying device more compact. This allows the conveying device to be used in space-constrained scenarios, optimizing space utilization. Simultaneously, the compact design directly reduces the use of other additional metal frames or support frames (i.e., there is no need to separately set up support frames to support the protective assembly 5 and the screw adjustment assembly 4), saving production costs. Furthermore, the more compact structure makes it easier to transport the conveying device as a whole. In addition, by setting the chain plate guide rail 12 and the conveyor chain 13, the conveying assembly 1 can be slightly offset or turned during use, allowing for flexible layout according to actual usage scenarios, improving the adaptability of the conveying device to different scenarios.

[0041] Combination Figure 1 , Figure 3As shown, the aforementioned conveying screw 3 is located on one side of the conveying assembly 1 in the second direction X2 and extends along the first direction X1. That is, the conveying screw 3 extends along the conveying direction of the material 2, and the conveying screw 3 can utilize the space between two adjacent threads to convey the material 2. Specifically, in the first direction X1, the size of the material 2 is less than or equal to the thread pitch of the conveying screw 3 (i.e., the distance between two adjacent threads). The material 2 is placed in the thread gap (between two adjacent threads) on the conveying screw 3. With the movement of the conveying assembly 1 (i.e., the movement of the conveying chain 13) and the rotation of the conveying screw 3, the material 2 will move along the first direction X1, realizing the conveying of the material 2. Furthermore, during this conveying process, the conveying screw 3 uses its own thread structure to separate adjacent materials 2, facilitating the entry of the material 2 into the subsequent filling machine.

[0042] Combination Figure 1 , Figure 3 As shown, the aforementioned conveying screw 3 is rotatably connected to the screw adjusting assembly 4. The screw adjusting assembly 4 can adjust the position of the conveying screw 3 in the second direction X2 and the third direction X3. The first direction X1, the second direction X2, and the third direction X3 are arranged at angles to each other, for example, 90°. Specifically, taking... Figure 3 Taking the perspective shown as an example, the screw adjustment assembly 4 can adjust the height of the conveying screw 3 in the vertical direction (up and down direction) and its position in the horizontal direction (left and right direction).

[0043] Specifically, such as Figure 3 The aforementioned screw adjustment assembly 4 includes a first adjustment component 41 and a second adjustment component 42.

[0044] The first adjustment component 41 is mounted on the base 11. This first adjustment component 41 can adjust the position of the conveying screw 3 in the third direction X3, that is, to... Figure 3 Taking the shown perspective as an example, the first adjustment component 41 is disposed on one side of the base 11 of the aforementioned conveying component 1 and is detachably connected to the base 11. The first adjustment component 41 can adjust the height of the conveying screw 3 in the vertical direction (up and down direction). The second adjustment component 42 is installed on the first adjustment component 41, and the aforementioned conveying screw 3 is rotatably connected to the second adjustment component 42. The second adjustment component 42 can adjust the position of the aforementioned conveying screw 3 in the second direction X2, that is, with Figure 4 Taking the perspective shown as an example, the second adjustment component 42 can adjust the position of the conveying screw 3 in the horizontal direction (left and right direction).

[0045] Thus, the conveying device provided by the embodiment can uniformly separate the plurality of materials 2 on the conveying assembly 1 by using the structure characteristic that the pitch of the conveying screw 3 is a fixed value (i.e., the distance between the adjacent two threads is a fixed value), so that the adjacent two materials 2 can keep a preset distance, and the materials 2 are prevented from being stuck or damaged by collision, thereby facilitating subsequent transfer work or other work. In addition, the screw adjusting assembly 4 including the first adjusting assembly 41 and the second adjusting assembly 42 is arranged, wherein the first adjusting assembly 41 is installed on the base 11 and can adjust the position of the conveying screw 3 in the third direction X3; the second adjusting assembly 42 is installed on the first adjusting assembly and rotatably connected with the conveying screw 3, and can adjust the position of the conveying screw 3 in the second direction X2. By the cooperation of the first adjusting assembly 41 and the second adjusting assembly 42, the position of the conveying screw 3 in the second direction X2 and the third direction X3 can be adjusted. In this way, the conveying device can adaptively adjust the distance between the conveying screw 3 and the materials 2 in the second direction X2 and the third direction X3 according to different types of materials 2, so that the height and size (diameter) of the conveying screw 3 are adapted to the materials 2, and the distance between the conveying screw 3 and the materials 2 is prevented from being too far or too close, so that the conveying screw 3 cannot normally convey the materials 2, and the conveying screw 3 can adapt to the conveying of different types of materials 2, and the applicability of the conveying device is improved. At the same time, the split shaft control (i.e., the first adjusting assembly 41 is separately arranged to adjust the position of the conveying screw 3 in the third direction X3, and the second adjusting assembly 42 is separately arranged to adjust the position of the conveying screw 3 in the second direction X2) can reduce the complexity of the mechanical structure, so that the overall structure is simpler, and the design and manufacture of the mechanical structure are facilitated; and the separate adjustment of the positions of the conveying screw 3 in the second direction X2 and the third direction X3 can avoid the mechanical coupling interference between the two directions, reduce the error transmission, and make the position adjustment in a single direction more accurate.

[0046] It can be understood that the conveying screw 3 needs a separate driving device (such as a rotating motor) as a power source, and the driving device is in transmission connection with one end of the conveying screw 3 through a transmission assembly (such as a shaft coupling, a reduction gear set, etc.). When the positions of the conveying screw 3 in the second direction X2 and the third direction X3 change, the length and height of the shaft coupling, which is a key component for transmitting power in the transmission assembly, should also change accordingly. Therefore, in the embodiment, the length and height of the shaft coupling are adjusted by the first adjusting assembly 41 and the second adjusting assembly 42. Figure 5 、 Figure 3As shown in the above conveying device for transmitting power components can be used with retractable universal joint 6, the driving half-coupling 61 and driven half-coupling 62 of the retractable universal joint 6 through the middle part of the flexible pipe 63 connection to adapt to the conveying screw 3 in the second direction X2 and the third direction X3 position changes.

[0047] Exemplary, the above driving device is a rotating motor, the output shaft of the rotating motor and the driving half-coupling 61 of the retractable universal joint 6 through the first gear set to achieve transmission connection.

[0048] Specifically, the first gear set includes the first bevel gear and the second bevel gear, the sum of the pitch angle of the first bevel gear and the second bevel gear is equal to the shaft intersection angle (in this embodiment, the axis of the first bevel gear and the second bevel gear is 90° orthogonal, that is, the shaft intersection angle is 90°). When the transmission ratio of the rotating motor and the retractable universal joint 6 is 1:1 (i.e. the first bevel gear and the second bevel gear are equal diameter transmission), the pitch angle of the first bevel gear and the second bevel gear is 45°, and the pitch cone vertex of the first bevel gear and the second bevel gear coincides with the intersection of the axes of the two; when the transmission ratio of the rotating motor and the retractable universal joint 6 is changed according to the actual use requirements, for example, the transmission ratio needs to be changed to 2:1 (i.e. the first bevel gear and the second bevel gear are non-equal diameter transmission), at this time, the pitch angle of the two needs to be adjusted according to the tooth ratio of the two. And r1+r2=90° two formula calculation, in which Z1, Z2 are the number of teeth of the first bevel gear and the second bevel gear, respectively, and r1, r2 are the pitch angle of the first bevel gear and the second bevel gear. For example, Z1=20, Z2=40, r1≈26.6°, r2≈63.4°. In addition, the large end face modulus of the first bevel gear and the second bevel gear is equal to ensure the pitch matching, and the pressure angle of the first bevel gear and the second bevel gear is the standard straight bevel gear pressure angle, i.e. 20°; of course, when the first bevel gear and the second bevel gear are helical bevel gears, the pressure angle of the two can be extended to 22.5°.

[0049] The motor output shaft is connected with the first bevel gear, for example, the two are connected by key connection, specifically, a key groove (flat key or spline) is processed on the motor output shaft, and a corresponding key groove is designed on the inner side wall of the mounting hole of the first bevel gear, so that the two can be connected by key to transmit torque; for example, the motor output shaft and the first bevel gear are connected by the form of shaft shoulder and locking nut, specifically, a shaft shoulder segment and a threaded segment are processed on the end of the motor output shaft, the mounting hole of the first bevel gear is arranged on the shaft shoulder segment of the motor output shaft and the end face of the first bevel gear is fitted with the shaft shoulder, then a round nut is installed on the threaded segment to cooperate with a stop washer to prevent loosening, so that the connection between the motor output shaft and the first bevel gear is achieved.

[0050] The second bevel gear is connected with the driving half-coupling 61 of the telescopic universal coupling 6, and the connection between the two is achieved in the following manner, for example: a coupling flange is arranged at the end of the driving half-coupling 61, a bevel gear shaft end flange is arranged on the second bevel gear, and the driving half-coupling 61 is connected with the second bevel gear through the coupling flange and the bevel gear shaft end flange; or, a transition shaft is arranged between the driving half-coupling 61 and the second bevel gear, and the driving half-coupling 61 and the second bevel gear are connected with the two ends of the transition shaft through key connection, so as to indirectly achieve the connection between the driving half-coupling 61 and the second bevel gear.

[0051] The driven half-coupling 62 of the telescopic universal coupling 6 is connected with the conveying screw 3 through a second gear set.

[0052] Specifically, the second gear set includes a third bevel gear and a fourth bevel gear in meshing connection, wherein the third bevel gear has the same structure as the second bevel gear, and the sum of the pitch angles of the fourth bevel gear and the third bevel gear is equal to the shaft intersection angle (in this embodiment, the shaft lines of the third bevel gear and the fourth bevel gear are arranged at 90°, i.e., the shaft intersection angle is 90°). The pitch angles of the fourth bevel gear and the third bevel gear can be set according to the actual transmission ratio, for example, if the transmission ratio of the telescopic universal coupling 6 and the conveying screw 3 is 1:1, the pitch angles of the fourth bevel gear and the third bevel gear are both 45°, and of course, the pitch angles of the fourth bevel gear and the third bevel gear can also be set by referring to the calculation method of the pitch angles of the first bevel gear and the second bevel gear, which will not be described herein again.

[0053] The third bevel gear is connected with the driven half-coupling 62 in the following manner, for example, through flange connection or indirect connection through a transition shaft, and the connection manner can be referred to the connection manner of the second bevel gear and the driving half-coupling 61, which will not be described herein again.

[0054] The fourth bevel gear is connected with the conveying screw 3 in the following manner, for example, through key connection or through the form of a shaft shoulder and a locking nut, and the connection manner can be referred to the connection manner of the first bevel gear and the motor output shaft, which will not be described herein again.

[0055] As can be seen from the above settings, when the rotary motor rotates, the output shaft of the motor rotates, which drives the first bevel gear connected to the output shaft to rotate. The first bevel gear transmits power to the second bevel gear through the meshing action between the gears. At this time, due to the structural characteristics of the bevel gear, the power transmission direction rotates by 90°. Subsequently, the second bevel gear drives the retractable universal coupling 6 to rotate, which in turn drives the third bevel gear, which is also connected to the retractable universal coupling 6, to rotate. The third bevel gear transmits power to the fourth bevel gear through the meshing action between the gears. At this time, due to the structural characteristics of the bevel gear, the power transmission direction rotates by 90° again. Finally, the fourth bevel gear transmits power to the conveying screw 3, thus realizing the rotary motor (drive device) driving the conveying screw 3 to rotate.

[0056] It is easy to understand that the aforementioned screw adjustment assembly 4 can be set in multiple sets according to the length of the conveying screw 3. For example, screw adjustment assemblies 4 can be set in the middle of the conveying screw 3 and at the end of the conveying screw 3 away from the drive device. This not only enables the adjustment of the position of the conveying screw 3 in the second direction X2 and the third direction X3, but also enables the use of multiple sets of screw adjustment assemblies 4 to provide support and fixation for the conveying screw 3, thereby improving the stability of the operation of the conveying screw 3.

[0057] In some embodiments, combined with Figure 6 to Figure 8 , Figure 6 to Figure 8 As shown, the first adjustment assembly 41 includes a first adjustment bracket 411 and a first fixing member. The first adjustment bracket 411 includes a first connecting portion 4111 and a second connecting portion 4112. Figure 3 As shown, a first adjustment hole 4113 extending in a third direction X3 is provided in the first connecting portion 4111 of the first adjustment bracket 4111. This first adjustment hole 4113 is, for example, an oblong hole or a long rectangular hole extending in a third direction X3. The first adjustment bracket 411 can be detachably connected to the base 11 by a first fixing member passing through the first adjustment hole 4113. Here, the first fixing member is, for example, a bolt. It is easy to understand that the location of the first adjustment hole 4113 is not limited to the first connecting portion 4111. It can also be provided on the base 11 (i.e., on the outer wall of the base 11 on the side closest to the first adjustment bracket 411) with an opening in a second direction X2 and extending in a third direction X3. Furthermore, it is possible to simultaneously provide first adjustment holes 4113 with openings in a second direction X2 and extending in a third direction X3 on both the first connecting portion 4111 and the base 11. Those skilled in the art can flexibly choose the configuration according to actual usage requirements, and no further limitations are imposed here.

[0058] For example, a mounting plate 14 is provided on the outer side wall of the base 11 of the conveying assembly 1. Bolt holes are provided on the mounting plate 14. When the first adjusting bracket 411 needs to be installed on the base 11, the bolt is passed through the first adjusting hole 4113 and the bolt hole on the mounting plate 14 simultaneously along the second direction X2. The first adjusting bracket 411 and the conveying assembly 1 are detachably connected by tightening the bolt. When it is necessary to adjust the position of the conveying screw 3 in the third direction X3, the bolt passing through the first adjusting hole 4113 is loosened. At this time, the first adjusting bracket 411 can move along the extension direction of the first adjusting hole 4113, that is, along the third direction X3, thereby driving the conveying screw 3 to move in the third direction X3, so as to realize the adjustment of the position of the conveying screw 3 in the third direction X3.

[0059] In some embodiments, combined with Figure 9 to Figure 11 , Figure 9 to Figure 11 As shown, the second adjustment assembly 42 includes a second adjustment bracket 421 and a second fixing member. The second adjustment bracket 421 includes a third connecting portion 4211 and a fourth connecting portion 4212. Figure 3 As shown, the third connecting portion 4211 of the second adjusting bracket 421 is provided with a second adjusting hole 4213 that opens along the third direction X3 and extends along the second direction X2. This second adjusting hole 4213 is, for example, an oblong hole or an elongated rectangular hole extending along the second direction X2. The second adjusting bracket 421 is detachably connected to the second connecting portion 4112 via a second fixing member (e.g., a bolt) passing through the second adjusting hole 4213. The conveying screw 3 is rotatably connected to the fourth connecting portion 4212 of the second adjusting bracket 421. It is easy to understand that the location of the second adjustment hole 4213 is not limited to the third connecting part 4211. Alternatively, a second adjustment hole 4213 can be provided on the second connecting part 4112, opening in the third direction X3 and extending in the second direction X2. Furthermore, second adjustment holes 4213 can be provided on both the third connecting part 4211 and the second connecting part 4112, opening in the third direction X3 and extending in the second direction X2. Those skilled in the art can flexibly choose the appropriate configuration based on actual usage requirements, and no further limitations are made here. In addition, the location of the first adjustment hole 4113 does not affect the location of the second adjustment hole 4213. In other words, the three configurations of the first adjustment hole 4113 and the three configurations of the second adjustment hole 4213 are complementary and can be flexibly combined according to actual usage requirements, which will not be exhaustively listed here.

[0060] Exemplarily, a bolt hole is arranged on the second connecting portion 4112 of the first adjusting bracket 411, when the second adjusting bracket 421 needs to be installed on the first adjusting bracket 411, the bolt is simultaneously passed through the second adjusting hole 4213 and the bolt hole of the second connecting portion 4112 along the third direction X3, and the detachable connection between the second adjusting bracket 421 and the first adjusting bracket 411 is realized by fastening the bolt; when the position of the conveying screw 3 in the second direction X2 needs to be adjusted, the bolt passing through the second adjusting hole 4213 is loosened, at this time, the second adjusting bracket 421 can move along the extension direction of the second adjusting hole 4213, that is, move in the second direction X2, and further can drive the conveying screw 3 to move in the second direction X2, so as to realize the adjustment of the position of the conveying screw 3 in the second direction X2.

[0061] In the conveying device, the first adjusting bracket 411 including the first connecting portion 4111 and the second connecting portion 4112 is arranged, the first adjusting hole 4113 extending along the third direction X3 is arranged on the first connecting portion 4111, the first adjusting bracket 411 is detachably connected with the conveying assembly 1 through the first adjusting hole 4113; and the second adjusting bracket 421 including the third connecting portion 4211 and the fourth connecting portion 4212 is arranged, the second adjusting hole 4213 extending along the second direction X2 is arranged on the third connecting portion 4211, and the second adjusting bracket 421 is detachably connected with the first adjusting bracket 411 through the second adjusting hole 4213. In this way, moving the first adjusting bracket 411 along the extension direction of the first adjusting hole 4113 can realize the adjustment of the position of the conveying screw 3 in the third direction X3, and moving the second adjusting bracket 421 along the extension direction of the second adjusting hole 4213 can realize the adjustment of the position of the conveying screw 3 in the second direction X2, so the structure and principle are simple, and the processing, manufacturing, maintenance and repair are convenient.

[0062] It is not difficult to understand that in order to achieve the effect of adjusting the position of the conveying screw 3 in the second direction X2 and the third direction X3, the above-mentioned first adjusting assembly 41 and the second adjusting assembly 42 can also be set in other ways. For example, the first adjusting assembly 41 includes a first adjusting support 411, and a first connecting part 4111 of the first adjusting support 411 is connected with the base 11 of the conveying assembly 1 through a sliding rail or a sliding groove, both of which extend along the third direction X3. The type of the sliding rail is a dovetail sliding rail or an inverted trapezoidal sliding rail, and the type of the sliding groove is matched with the type of the sliding rail. In addition, a limiting assembly and a locking assembly are arranged on the first adjusting support 411 or the base 11 of the conveying assembly 1, respectively, to limit the sliding distance and lock the sliding position. In this way, the position of the conveying screw 3 in the third direction X3 can be adjusted through the first adjusting assembly 41. Similarly, the second adjusting assembly 42 can also be set in the same way, that is, the second adjusting assembly 42 includes a second adjusting support 421, and a third connecting part 4211 of the second adjusting support 421 is connected with a second connecting part 4112 of the first adjusting support 411 through a sliding rail or a sliding groove. For details, refer to the setting mode of the first adjusting assembly 41, which will not be described here. Through the above-mentioned setting, the position of the conveying screw 3 in the second direction X2 and the third direction X3 can also be adjusted. Further, a gear and a rack structure can be additionally arranged between the first connecting part 4111 of the first adjusting support 411 and the base 11 of the conveying assembly 1, and between the third connecting part 4211 of the second adjusting support 421 and the second connecting part 4112 of the first adjusting support 411. The driving motor drives the gear to rotate, and the gear and the rack are matched to realize the electric adjustment of the position of the conveying screw 3 in the second direction X2 and the third direction X3. Through the above-mentioned setting, the position adjustment of the conveying screw 3 is more labor-saving, saves manpower, and saves adjustment time.

[0063] It should be noted that the different setting modes (setting adjusting holes or setting sliding rails, sliding grooves or setting adjusting gears and racks) of the above-mentioned first adjusting assembly 41 and the second adjusting assembly 42 belong to completely parallel different technical solutions, both of which have good beneficial effects, and a person skilled in the art can choose flexibly according to actual use requirements. Moreover, a person skilled in the art can also combine different setting modes according to actual use requirements, such as detachable connection between the first adjusting assembly 41 and the base 11 of the conveying assembly 1 through the first adjusting hole 4113, and sliding connection between the second adjusting assembly 42 and the first adjusting assembly 41 through the setting sliding rail and the sliding groove. The combination mode of different technical solutions will not be enumerated here.

[0064] In some embodiments, as Figure 3As shown, the conveying device further comprises a protection assembly 5. The protection assembly 5 is located on the other side of the conveying assembly 1 in the second direction X2 and extends along the first direction X1. That is, the screw adjusting assembly 4 is arranged on one side of the base 11 of the conveying assembly 1, and the protection assembly 5 is arranged on the other side of the base 11. The protection assembly 5 can prevent the material 2 conveyed by the conveying assembly 1 from falling in the second direction X2. By arranging in this way, the reliability of the conveying device when conveying the material 2 can be improved.

[0065] As shown in the drawings, Figure 3 As shown, the protection assembly 5 comprises a mounting bracket 51, a third adjusting assembly 52, and a protection member 53. The mounting bracket 51 comprises a fifth connecting portion 511 and a sixth connecting portion 512. The fifth connecting portion 511 of the mounting bracket 51 is connected to the conveying assembly 1 (for example, bolted to the outer side wall of the base 11), the third adjusting assembly 52 is connected to the sixth connecting portion 512 of the mounting bracket 51 (for example, bolted or clamped), and the protection member 53 is connected to the third adjusting assembly 52. The protection member 53 is, for example, a plate-shaped structure extending along the conveying direction of the material 2 (i.e., the first direction X1), or a rod-shaped structure extending along the conveying direction of the material 2. The third adjusting assembly 52 can adjust the position of the protection member 53 in the second direction X2. By arranging in this way, the third adjusting assembly 52 in the protection assembly 5 can adaptively adjust the distance between the protection member 53 and the material 2 according to the size (diameter) of the material 2 conveyed by the conveying assembly 1, so that the protection assembly 5 can be suitable for preventing the material 2 of different sizes (diameters) from falling, thereby improving the practicability of the conveying device.

[0066] As shown in the drawings, Figure 1 As shown, the third adjusting assembly 52 comprises a support member 521, a protection member mounting member 522, and a locking member 523. Specifically, one end of the support member 521 is connected to the sixth connecting portion 512 of the mounting bracket 51 (for example, bolted), the protection member mounting member 522 is slidingly connected to the other end of the support member 521 in the second direction X2. For example, a connecting through hole is formed in the support member 521 in the second direction X2, and the shape and size of the connecting through hole are the same as the shape and size of the cross-sectional shape of the protection member mounting member 522 (the cross section is parallel to the third direction X3 and perpendicular to the second direction X2), so that the protection member mounting member 522 can be inserted into the connecting through hole of the support member 521, and the protection member mounting member 522 can slide in the second direction X2. In the second direction X2, the protection member 53 is located between the support member 521 and the conveying screw 3, and the protection member 53 is connected to the protection member mounting member 522. For example, the two are connected by welding or detachable connection by bolts.

[0067] The locking member 523 can limit the movement of the guard mounting member 522 in the second direction X2. For example, the locking member 523 is an adjusting knob or a bolt with external threads provided on the outer side wall, and a locking hole is formed in the support member 521 in the third direction X3. The locking hole is provided with internal threads, and the center lines of the connecting hole and the locking hole are at an angle, for example, 90°. The guard mounting member 522 is inserted into the connecting hole in the second direction X2, and the locking member 523 is inserted into the locking hole in the third direction X3. When the locking member 523 rotates around its center line (for example, clockwise), the locking member 523 moves towards the guard mounting member 522 under the cooperation of the internal and external threads, and the end of the locking member 523 close to the guard mounting member 522 presses the guard mounting member 522, limiting the movement of the guard mounting member 522 in the second direction X2 by the friction between the locking member 523 and the guard mounting member 522. When it is necessary to adjust the position of the guard mounting member 522 in the second direction X2, the locking member 523 is rotated counterclockwise, and the locking member 523 moves away from the guard mounting member 522, and the end of the locking member 523 close to the guard mounting member 522 releases the guard mounting member 522, so that the guard mounting member 522 can move in the second direction X2.

[0068] In the conveying device, the third adjusting assembly 52 is provided with the support member 521, the guard mounting member 522 connected to the support member 521 in the second direction X2, the guard 53 connected to the guard mounting member 522, and the locking member 523. In this way, the distance between the guard 53 and the material 2 on the conveying assembly 1 can be adjusted by sliding the guard mounting member 522 in the second direction X2, and the position of the guard mounting member 522 in the second direction X2 can be limited by adjusting the locking member 523. The flexible adjustment of the guard 53 and the locking of the position of the guard 53 in the second direction X2 can be realized, and the structure is simple and the operation is convenient.

[0069] In some embodiments, the third adjusting assembly 52 further comprises a third fixing member; the fifth connecting portion 511 of the mounting bracket 51 in the protective assembly 5 is provided with a third adjusting hole which is opened along the second direction X2 and extends along the third direction X3, for example, a waist-shaped hole or a long strip-shaped rectangular hole which extends along the third direction X3, and the mounting bracket 51 is detachably connected with the base 11 by the third fixing member (for example, a bolt) which is threaded in the third adjusting hole. That is, the mounting bracket 51 is detachably connected with the outer side wall of the base 11 by threading the third fixing member in the third adjusting hole. It is not difficult to understand that the third adjusting hole is not limited to be arranged on the fifth connecting portion 511, but can also be arranged on the base 11 (that is, on the outer side wall of the side of the base 11 which is close to the protective assembly 5), or both the fifth connecting portion 511 and the base 11 can be provided with the third adjusting hole which is opened along the second direction X2 and extends along the third direction X3, and the person skilled in the art can flexibly select and arrange according to the actual use requirements, which is not limited here.

[0070] Exemplarily, the base 11 of the conveying assembly 1 is provided with a bolt hole, the bolt is threaded along the second direction X2 through the third adjusting hole and the bolt hole on the base 11, and the mounting bracket 51 is detachably connected with the conveying assembly 1 by fastening the bolt. In addition, the mounting bracket 51 can be moved along the extension direction of the third adjusting hole (that is, the third direction X3) by loosening the bolt. By such arrangement, the position of the protective assembly 5 in the third direction X3 can be adjusted, so that the protective member 53 in the protective assembly 5 can adaptively adjust its height (that is, the position in the third direction X3) according to the material 2 of different heights, so as to ensure better anti-toppling effect on the material 2 of different heights, and improve the practicability of the conveying device.

[0071] In some embodiments, as Figure 12As shown, the conveying screw 3 of the conveying device comprises a plurality of sub-screws 31 arranged along the first direction X1, for example, 3 sub-screws 31, and adjacent two sub-screws 31 are connected through a screw connecting assembly 32. By segmenting the conveying screw 3, if a sub-screw 31 is damaged during actual use, only the damaged part needs to be replaced instead of the entire conveying screw 3, thereby reducing the maintenance cost and time. Meanwhile, for a longer conveying line, the length of the conveying screw 3 also needs to be increased synchronously, and the segmented combined structure of the conveying screw 3 can increase the overall rigidity and reduce vibration and deformation (the length of the shaft-shaped part is increased, the bending force borne in the process of torsion is increased, which leads to an increase in the deformation amount of the shaft-shaped part itself). In addition, the segmented combined structure of the conveying screw 3 can also solve the manufacturing process problem of a large screw and reduce the transportation difficulty.

[0072] Exemplarily, as shown in Figure 12 The screw connecting assembly 32 comprises a connecting shaft 321. The connecting shaft 321 penetrates the screw adjusting assembly 4 along the first direction X1 and is rotatably connected with the screw adjusting assembly 4, and the two ends of the connecting shaft 321 are respectively detachably connected with the adjacent two sub-screws 31. Specifically, the fourth connecting part 4212 of the second adjusting bracket 421 in the second adjusting assembly 42 is provided with a bearing mounting hole, and the connecting shaft 321 is arranged to pass through the rotating bearing and install the rotating bearing and the connecting shaft 321 in the bearing mounting hole of the fourth connecting part 4212 of the second adjusting bracket 421, so as to realize the rotatable connection between the connecting shaft 321 and the screw adjusting assembly 4. In addition, the connecting shaft 321 is provided with a connecting spline at both ends, and the two sub-screws 31 to be connected are respectively provided with corresponding spline flanges, and the detachable connection between the connecting shaft 321 and the sub-screws 31 can be realized by connecting the connecting splines at both ends of the connecting shaft 321 with the spline flanges at the ends of the two sub-screws 31. It can be understood that, in order to improve the connection firmness of the connecting shaft 321 and the sub-screws 31, a conical pin, a fixed flange, a spline flange, a retaining ring, a screw and the like can be additionally arranged at the connecting position of the connecting shaft 321 and the sub-screws 31, and a person skilled in the art can selectively arrange them according to actual use requirements.

Further, a spline flange 324 is arranged in the flange mounting groove, which is arranged on the upper surface of the fixed flange 322, and the spline flange 324 is connected with the fixed flange 322 by the screw 325.
