[0033] Reference below Figures 1 to 3 The electric drum of the present invention will be described in detail.

[0034] The electric roller is usually installed on a conveying device. The conveying device includes two frames. A conveying path is formed between the two frames. The electric roller is installed on the conveying path. The two ends of the electric roller are respectively inserted into the connecting holes of the two frames. The roller body 100 in the middle of the electric roller is located between the two frames and is used to drive the conveyor belt to move. In order to achieve stable installation of the electric roller on the conveying device, the length of the electric roller needs to be greater than the distance between the two frames, so that after the electric roller is installed on the conveying path, the two ends of the electric roller can be respectively extended into the two frames; when installing the electric roller, it is necessary to first insert one end of the electric roller into one of the frames, and then use external force to press the other end of the electric roller into the other frame. Therefore, in order to facilitate the installation of the electric roller, the distance between the two frames often needs to be greater than the length of the roller body 100. Accordingly, after the electric roller is installed, a large installation gap is often left between the roller body 100 and the frame. When the electric roller is working, the electric roller is prone to axial shaking.

[0035] In order to reduce the axial shaking of the electric drum during operation, refer to Figure 1 and Figure 2The electric drum of the embodiment of the present invention includes a drum body 100 and a latch shaft module 200; a plug-in hole extending left and right is formed at the right end of the drum body 100; the latch shaft module 200 includes a latch shaft 210 and an elastic snap-fit ​​structure, the latch shaft 210 includes an insertion section and a connecting section, the insertion section is connected to the left end of the connecting section, the insertion section is inserted into the plug-in hole, the connecting section is located on the right side of the plug-in hole, and is used to be inserted into the frame of the conveying equipment, the elastic snap-fit ​​structure is arranged on the insertion section, and the elastic snap-fit ​​structure can be partially inserted into the snap-fit ​​groove 101 under the action of its own elastic force.

[0036] When installing the electric drum of this embodiment, the drum body 100 can be first placed on the conveying path between the two frames, and the right end of the drum body 100 is close to the frame, and the plug-in hole is opposite to the connecting hole of the frame. Then, the staff can use the latch shaft 210 to pass through the connecting hole and the plug-in hole from right to left in sequence until the elastic snap-in structure is opposite to the snap-in groove 101 on the wall of the plug-in hole. At this time, under the elastic force of the elastic snap-in structure itself, the elastic snap-in structure is partially inserted into the snap-in groove 101 to achieve the locking and fixation of the latch shaft 210.

[0037] It can be understood that since the drum body 100 can be placed on the conveying path first, the relative distance between the two frames can be set to be consistent with the length of the drum body 100. After the electric drum is installed on the conveying equipment, the installation gap between the drum body 100 and the frame is smaller, and the axial shake generated by the electric drum during operation is also smaller.

[0038] refer to Figure 2 In some embodiments of the present invention, the drum body 100 includes a cylinder 110, a bearing seat 120, a bearing 130, a sleeve 140 and a sealing cover 150. The bearing seat 120 is connected to the right end of the cylinder 110. The sleeve 140 and the sealing cover 150 are both inserted into the bearing seat 120, and the sleeve 140 is located on the left side of the sealing cover 150. The bearing seat 120 and the sleeve 140, as well as the bearing seat 120 and the sealing cover 150 are rotatably connected through the bearing 130. The inner hole of the sleeve 140 and the inner hole of the sealing cover 150 jointly form a plug-in hole, and the connection between the sleeve 140 and the sealing cover 150 forms a snap-in groove 101.

[0039] It can be understood that since the clamping groove 101 is formed at the connection between the shaft sleeve 140 and the sealing cover 150,

[0040] Therefore, the staff can adjust the size of the snap-in groove 101 by adjusting the distance between the shaft sleeve 140 and the sealing cover 150 in the left-right direction, so that the snap-in groove 101 can adapt to elastic snap-in structures of different sizes.

[0041] Optionally, in other embodiments of the present invention, without considering the adjustable size of the snap-in groove 101, the snap-in groove 101 can also be separately set on the inner hole wall of the sleeve 140, or separately set on the inner hole wall of the sealing cover 150, or the sleeve 140 and the sealing cover 150 can be set homogeneously and integrally.

[0042] In some special cases, such as when the electric roller is damaged, the staff needs to replace the electric roller on the conveying equipment. After the latch shaft 210 is inserted into the plug hole, when the latch shaft 210 needs to be removed from the plug hole, the staff often needs to pull the latch shaft 210 outward with force, so that the elastic clamping structure itself can shrink under the action of the groove wall of the clamping groove 101 to disengage from the clamping groove 101, so that the latch shaft 210 can be disengaged from the plug hole. In the above process, the staff often needs to apply a large pulling force to the latch shaft 210, which is not only inconvenient to operate, but also easy to damage the elastic clamping structure.

[0043] In order to facilitate the staff to disassemble the electric drum, refer to Figure 2 In some embodiments of the present invention, a through hole extending left and right is provided in the latch shaft 210, the right end of the through hole is connected to the outside world, and a mounting hole connected to the outside world is opened on the hole wall of the through hole; the elastic snap-fit ​​structure includes a pressing shaft 220, an elastic connector 230 and a snap-fit ​​member 240, the pressing shaft 220 extends in the left and right directions and is inserted into the through hole, the elastic connector 230 is arranged in the through hole and is located on the left side of the pressing shaft 220, the left and right ends of the elastic connector 230 are respectively connected to the hole wall of the through hole and the pressing shaft 220, a contact surface is formed on the pressing shaft 220, and the snap-fit ​​member 240 is inserted into the mounting hole and contacts the contact surface.

[0044] In the above embodiment, when the electric roller needs to be installed, the staff can overcome the elastic force of the elastic connector 230 to press the pressing shaft 220 to the left, and the pressing shaft 220 can move to the left to avoid the clamping member 240, so that the clamping member 240 can be completely retracted into the installation hole. At this time, the latch shaft 210 can be smoothly inserted into the installation hole and the insertion hole. Then, the staff releases the pressing shaft 220, and under the elastic force of the elastic connector 230, the pressing shaft 220 moves to the left, and the abutment on the pressing shaft 220 is pressed. The surface pushes the clamping piece 240 to move upward, and the clamping piece 240 extends to the mounting hole and is inserted into the clamping groove 101 to realize the installation of the electric drum on the frame; when the electric drum needs to be disassembled, the staff can overcome the elastic force of the elastic connecting piece 230 to press the pressing shaft 220 to the left, and the pressing shaft 220 can move to the left to avoid the clamping piece 240, so that the clamping piece 240 can be completely retracted into the mounting hole. At this time, the latch shaft 210 can smoothly disengage from the insertion hole and the mounting hole to realize the disassembly of the electric drum.

[0045] It is understandable that the arrangement of the pressing shaft 220 and the elastic connector 230 facilitates the staff to control the insertion or disengagement of the clamping member 240 into or out of the clamping groove 101 through the pressing shaft 220, thereby reducing the difficulty of installing and disassembling the electric drum of this embodiment.

[0046] Specifically, refer to Figure 3 In some embodiments of the present invention, the abutment surface includes a first sub-abutment surface 221a, and the pressing shaft 220 includes a first abutment section 221. The first abutment section 221 is a truncated cone with a cross-sectional area gradually decreasing to the right, and the outer peripheral surface of the first abutment section 221 forms a first sub-abutment surface 221a.

[0047] It is understandable that since the first sub-abutment surface 221a is the outer peripheral surface of the truncated cone-shaped first abutment section 221, after the pressing shaft 220 rotates, when the pressing shaft 220 moves left and right, a portion of the first sub-abutment surface 221a can always abut against the clamping member 240.

[0048] When the electric drum is working, the clamping member 240 is easily pressed downward by the vibration of the electric drum itself. The pressing shaft 220 is likely to move to the left by overcoming the elastic force of the elastic connecting member 230. At this time, the latch shaft 210 is likely to be separated from the plug hole. In order to improve the self-locking property of the latch shaft 210, refer to Figure 3 In some embodiments of the present invention, the abutment surface also includes a second sub-abutment surface 222a, and the pressing shaft 220 also includes a second abutment section 222, the second abutment section 222 is cylindrical, and the circumferential surface of the second abutment section 222 forms a second sub-abutment surface 222a; the second abutment section 222 is connected to the left end of the first abutment section 221, and the first sub-abutment surface 221a is connected to the second sub-abutment surface 222a.

[0049] It can be understood that when the pin shaft 210 is inserted into the plug hole, under the elastic force of the elastic connecting member 230, the pressing shaft 220 can move to the right so that the second sub-abutment surface 222a abuts against the clamping member 240. Since the direction in which the clamping member 240 applies thrust to the second sub-abutment surface 222a is perpendicular to the second sub-abutment surface 222a, it is difficult for the clamping member 240 to push the pressing shaft 220 to move left and right through the second sub-abutment surface 222a when the clamping member 240 vibrates in the vertical direction, so that the clamping member 240 can be stably inserted into the clamping groove 101, thereby improving the self-locking property of the pin shaft 210.

[0050] In some embodiments of the present invention, in order to adjust the elastic force of the elastic connector 230, refer to Figure 2The latch shaft 210 includes a shaft body 211 and a screw 212. The insertion hole is provided in the shaft body 211. The screw 212 is provided on the left side of the shaft body 211 and the thread is inserted into the insertion hole. The left end of the elastic connector 230 is connected to the screw 212. It can be understood that by rotating the screw 212, the depth of the screw 212 inserted into the insertion hole can be adjusted, so that the compression amount of the elastic connector 230 can be adjusted, thereby realizing the adjustment of the elastic force of the elastic connector 230.

[0051] In some embodiments of the present invention, the clamping member 240 is spherical. It is understandable that the spherical clamping member 240 is less obstructed by the groove wall of the clamping groove 101 and the hole wall of the mounting hole.

[0052] It is understandable that when the latch shaft module 200 rotates, after the latch shaft 210 is inserted into the plug hole, the clamping member 240 may be misaligned with the clamping groove 101, and at this time, the clamping member 240 cannot be inserted into the clamping groove 101. After the latch shaft 210 is inserted into the plug hole, in order to ensure that the clamping groove 101 can always be inserted into the clamping groove 101, in some embodiments of the present invention, the clamping groove 101 is set as an annular groove.

[0053] The conveying device provided in accordance with the second aspect of the embodiment of the present invention includes the electric roller provided in the first aspect of the embodiment of the present invention, a conveying path is formed in the conveying device, and the conveying device also includes a frame located in the width direction of the conveying path, a connecting hole is provided on the frame, and the connecting section is inserted into the connecting hole.

[0054] Refer to the following Figure 4 The method for installing the electric drum according to the third aspect of the present invention will be described in detail.

[0055] The installation method of the electric roller provided in the third aspect of the present invention is applied to the conveying device provided in the second aspect of the present invention, and the installation method includes the following steps:

[0056] Step S100, placing the drum body 100 of the electric drum in the conveying path, and making the plug-in hole of the drum body 100 face the connecting hole of the frame;

[0057] Step S200 , insert the latch shaft module 200 into the connecting hole and the plugging hole in sequence, and insert the elastic snap-fit ​​structure into the snap-fit ​​groove 101 .

[0058] It can be understood that since the drum body 100 is first placed in the conveying path, the distance between the two frames can be kept consistent with the length of the drum body 100, thereby reducing the installation gap between the drum body 100 and the frame, and then during the operation of the electric drum, the axis shaking generated by the electric drum is smaller.

[0059] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
