[0002] The loading head is used for connecting the goods source and the conveying device. At present, when goods need to be carried to the loading head, the goods are moved to the loading end of the loading head, and then the goods are moved to the conveying device under the action of the conveying belt of the loading head for conveying.

[0003] However, when heavy goods are carried, the artificial burden and labor intensity are still increased. UTILITY MODEL CONTENT

[0004] In order to overcome the above-mentioned defects, the utility model discloses a liftable loading head, which is adjusted to a position lower than the goods according to the need when the goods need to be carried to the loading head, so that when the goods need to be transferred to the loading head, only the friction needs to be overcome to pull the goods to the loading head, and the gravity does not need to be overcome to carry the goods to the loading head, so that the applied force can be effectively reduced, and the burden of workers can be reduced.

[0005] The liftable loading head of the utility model comprises a base, further comprises: a conveying unit, the conveying unit is provided with a driving roller and a driven roller, and further comprises a conveying belt connected with the driving roller and the driven roller respectively; a lifting part is used for driving the conveying unit to rotate around the central axis of the driving roller; end shafts are arranged at both ends of the driving roller and are away from each other, further comprises a first flange sleeve connected with the end shaft and a second flange sleeve connected with the base, at least part of the first flange sleeve and the second flange sleeve are coaxially arranged, and a bushing coaxially arranged with the driving roller is further arranged between the first flange sleeve and the second flange sleeve.

[0006] The application has the following beneficial effects: by setting the end shaft on both ends of the driving roller and setting the first flange sleeve on the end shaft, the end shaft can be kept stable and will not rotate with the driving roller when the driving roller rotates to convey the material, thereby ensuring the stability of the conveying unit. Meanwhile, the second flange sleeve is set on the base, and the bushing is set between the first flange sleeve and the second flange sleeve, so that the loading head can be lifted smoothly, and the function of the driving roller for conveying goods does not interfere with the function of the loading head for lifting around the driving roller, thereby ensuring that the height of one end of the loading goods of the lifting loading machine of the application can be adjusted to the height convenient for receiving goods, and the conveying function of the conveying unit itself is not interfered. The application uses the axial direction of the driving roller as the rotation axis of the loading head, so that the overall structure of the loading head is more compact, and the self-gravity of the loading head that needs to be overcome when lifting is minimized.

[0007] Further, the first flange sleeve has a first connecting head extending outward in a direction away from the driving roller, and the first connecting head is sleeved on the outside of the end shaft in at least a partial axial direction.

[0010] Further, the driven roller has a main body part located in the middle region of the axial direction, and two center adjustment parts located at the ends of the main body part, and the outer diameter of the center adjustment part is smaller than that of the main body part. Thus, by making the outer diameter of the region close to the two ends of the driven roller slightly smaller and the middle slightly larger, the belt is inclined to force close to the two ends when it is not centered, so that it gradually recovers to the center under the action of its own tension. Please note that the outer diameter of the center adjustment part is only slightly smaller than the outer diameter of the main body part.

[0011] Further, the center adjustment part has at least one region with an outer diameter smaller than that of the main body part. It can also be a plurality of regions arranged in sequence, so that the driving roller has a gradually reduced outer diameter.

[0012] Further, the connecting plate is arranged to drive the driven roller to move, and the adjusting piece is arranged to be connected with the connecting plate, the adjusting piece is connected with the connecting plate, and the adjusting piece is arranged to move towards the driving roller.

[0032] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0033] See appendix Figures 1-8 As shown, this embodiment provides a liftable loading head for use in conjunction with a flexible rolling belt conveyor. In use, the liftable loading head is attached to the end of the flexible rolling belt conveyor via connecting lug 12. After the goods are first moved to the loading head, they are then transported by the loading head to the flexible rolling belt conveyor for corresponding conveying.

[0034] The liftable loading head of this embodiment includes a base 1, a conveying unit 2, and a lifting section. See attached diagram for details. Figure 2 As shown, the conveying unit 2 has a drive roller 21 and a driven roller 22, and also includes a conveyor belt 24 connected to the drive roller 21 and the driven roller 22 respectively; the lifting part is used to drive the conveying unit 2 to rotate around the central axis of the drive roller 21; end shafts 31 are provided at both ends of the drive roller 21, which are far apart from each other, and the end shafts 31 do not rotate with the driving action of the drive roller 21, and also include a first flange sleeve 32 connected to the end shafts 31 (see Appendix). Figure 3 (as shown), and the second flange sleeve 33 connected to the base 1 (see Appendix)Figure 4 As shown in the drawings, at least part of the first flange sleeve 32 and the second flange sleeve 33 are coaxially arranged with each other, and a bushing 34 coaxially arranged with the driving roller 21 is arranged between the first flange sleeve 32 and the second flange sleeve 33 (see the drawings). Figure 5 As shown in the drawings.

[0035] Therefore, when it is needed to carry the goods to the loading head, the upper end of the loading head is adjusted to a position lower than the goods as needed, and the goods are pulled to the loading head by overcoming the friction only, without the need to carry the goods to the loading head by overcoming the gravity again, so that the applied force can be effectively reduced, and the burden of the workers can be reduced.

[0036] The conveying belt can stably convey the goods under the driving of the driving roller 21 and the driven roller 22. The arrangement of the end shaft 31 enables the end shaft 31 to remain stable and not rotate with the driving roller 21 when the driving roller 21 rotates, thereby ensuring the stability of the conveying unit 2. The coaxial arrangement of the first flange sleeve 32 and the second flange sleeve 33, the connection of the first flange sleeve 32 and the second flange sleeve 33 with the end shaft 31 and the base 1 of the driving roller 21 respectively, and the arrangement of the bushing 34 between the first flange sleeve 32 and the second flange sleeve 33 enable the loading head to stably lift and lower, and the function of the driving roller 21 for conveying the goods and the function of the loading head for lifting and lowering by rotating around the driving roller 21 do not interfere with each other.

[0037] In some embodiments, the first flange sleeve 32 has a first connecting head 321 extending outward in a direction away from the driving roller 21, the first connecting head 321 is sleeved on the outside of the end shaft 31 in at least part of the axial direction, and the second flange sleeve 33 has a second connecting head 331 extending in a direction close to the driving roller 21. The inner diameter of the second connecting head 331 is greater than the outer diameter of the first connecting head 321, and the bushing 34 is arranged between the first connecting head 321 and the second connecting head 331. See the drawings. Figure 5 As shown in the drawings, in some embodiments, one end of the second connecting head 331 away from the main body of the second flange sleeve 33 has a retaining rim 3311 extending toward the first connecting head 321, so that one end of the bushing abuts against the retaining rim 3311 and the other end abuts against the guard plate 11, thereby achieving stable installation of the bushing 34.

[0038] In other possible embodiments, the opposite design can also be adopted, that is, the outer diameter of the second connecting head 331 is smaller than the inner diameter of the second connecting head 331, and it is only needed to ensure that there is a space for arranging the bushing 34 between the first connecting head 321 and the second connecting head 331.

[0039] In some embodiments, the base 1 has a guard plate 11 extending towards the side close to the conveying unit 2, and the second flange sleeve 33 is arranged on the guard plate 11. Thus, the present application, by arranging the guard plate 11, not only facilitates the fixed connection of the second flange sleeve 33, but also enables the lifting part to be shielded by the guard plate 11, so that the appearance of the liftable loading head is more neat and beautiful.

[0040] Referring to the accompanying drawings Figure 6 and Figure 7 As shown in the drawings, in some embodiments, the driven roller 22 has a main body part 221 located in the middle axial region thereof, and two centering adjustment parts 222 located at the two ends of the main body part 221 and symmetrical to each other, and the outer diameter of the centering adjustment part 222 is smaller than that of the main body part 221. Thus, by making the outer diameter of the driven roller 22 slightly smaller near the two ends and slightly larger in the middle, when the belt is not centered, the belt is tilted at the positions close to the two ends (in the direction of arrow A in the drawings) under the action of the self-tightening force of the belt, so that it gradually recovers to the centered state. Please note that the outer diameter of the centering adjustment part 222 is only slightly smaller than that of the main body part 221. Figure 7

[0041] In some embodiments, the centering adjustment part 222 has at least one region with an outer diameter smaller than that of the main body part 221. It can also be a plurality of regions arranged in steps, so that the driving roller 21 has an appearance with gradually reduced outer diameter.

[0042] Referring to the accompanying drawings Figure 8 In some embodiments, the present application further comprises a connecting plate 41 capable of driving the driven roller 22 to move, and further comprises an adjusting piece 42 capable of being connected with the connecting plate 41, and the adjusting piece 42 is capable of moving towards the direction close to or away from the driving roller 21. The liftable loading head of the present application further comprises a blocking piece 43 connected with the adjusting piece 42, and an adjusting bolt 44 used for abutting against the blocking piece 43 and capable of adjusting the position of the blocking piece 43, and the adjusting bolt 44 is fixed on the guard plate 11, and the axial direction of the adjusting bolt 44 is arranged along the direction away from the driving roller 21.

[0043] Correspondingly, at least one adjusting hole 111 (see the accompanying drawings Figure 9 ​As shown, the fixing bolt 45 passes through the adjusting hole 111 and is connected with the adjusting piece 42 and the connecting plate 41 respectively, and the adjusting piece 42 and the connecting plate 41 are located on two sides of the guard plate 11 respectively and are fixed under the action of the fixing bolt 45. Thus, the position of the fixing bolt 45 in the adjusting hole 111 can be adjusted under the pushing of the adjusting bolt 44, and then the relative position between the driven roller 22 and the driving roller 21 is adjusted, so that the effect of adjusting the belt tensioning is achieved to a certain extent. Meanwhile, in cooperation with the structure of the center adjusting part 222 of the driven roller 22, the driven roller 22 is adjusted to the appropriate tensioning position, so that the belt can be smoothly guided to the center position under the action of the center adjusting part 222. In some embodiments, the number of adjusting holes 111 is three and arranged in a triangular array, so that the position stability of the fine adjustment of the position of the driven roller 22 can be ensured.

[0044] In some embodiments, the tensioning adjusting roller 23 is further included to keep the belt of the loading head in a tensioning state. In some embodiments, the existing belt conveyor in the prior art is directly used as the conveying unit 2.

[0045] The first flange sleeve 32, the second flange sleeve 33 and the bushing 34 and other structures are arranged at the end of the driving roller 21 of the belt conveyor, and the belt conveyor is hinged with the base 1.

[0046] The accompanying drawings are combined with the detailed description Figure 10 As shown, in some embodiments, a plurality of cow eye balls 5 are further arranged on the edge of the bottom of the base 1 along the circumferential direction. Compared with the way of arranging the universal casters in the prior art, since the mounting axis of the caster and the rotation axis of the caster itself have a certain spacing, the way of mounting the universal caster must be able to cover the annular rotation area of the spacing. However, the present application directly uses the cow eye ball 5 as a turning structure, which can reduce the turning radius of the liftable loading head and further reduce the space required for work.

[0047] In some embodiments, the mounting notch 112 is further arranged on the guard plate 11, and the output end of the driving source is hingedly arranged at the corner part of the guard plate 11 body away from the driving roller 21 and provided with the mounting notch 112. The mounting notch 112 is used to provide a avoiding space for the installation of the lifting part, and the output end of the driving source is formed as a hinge point by the area of the guard plate 11 body located in the mounting notch 112, without the need to additionally arrange other hinge structures on the guard plate 11 body, so that the overall structure of the liftable loading head is more compact.

[0048] In some embodiments, a control box 6 is further arranged on the apron 11, and the driving sources of the driving roller 21 and the lifting part are in communication connection with the control box 6. Thus, the working of the driving sources of the driving roller 21 and the lifting part is controlled under the control of the control box 6.

[0049] The above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made according to the spirit and essence of the present application shall be covered within the protection scope of the present application.
