Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a tensioning mechanism for a velvet making and cleaning device. Background Art

[0002] In the automation industry, especially when new energy automation equipment is working continuously, it is easy to malfunction, such as loose screws and misalignment at the connection. At this time, it is easy to lag if the fault is handled manually and the equipment is stopped immediately, which interrupts the continuity of the operation of the automation equipment. Therefore, it is necessary to install a set of horizontal tensioning devices on the equipment. The existing technologies are mainly divided into fixed tensioning, constant tension tensioning, etc. The existing spiral tensioning mechanism is a device that is locked after reaching the required pressure through manual adjustment or adjustment by a small hydraulic cylinder. It is characterized by simple structure and compact layout. However, the tension and stroke of manual adjustment are small, and the adjustment of the pulling force is based on observation experience and the operating status of the equipment. It cannot automatically keep the pre-tension constant and needs to be adjusted frequently. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the magnitude of the tensioning force of the connecting piece in the horizontal direction cannot be adjusted conveniently and reliably.

[0004] To this end, the utility model provides a tensioning mechanism for a velvet cleaning device, comprising:

[0005] An outer cover component, wherein the outer cover component has an accommodating space, a driving member is rotatably arranged inside the accommodating space, the driving member is formed in a rod shape, two fixing members are arranged on the driving member, and the driving member drives the two fixing members to approach each other; a reset member is arranged between the two fixing members, and the reset member drives the two fixing members to move away from each other; a stop member is also arranged on the fixing member, and the stop member passes through the fixing member and forms an abutting state and a non-abutting state with the driving member.

[0006] Furthermore, the outer cover assembly includes a bottom plate, two back plates and two side plates, the back plate and the side plates are both vertically arranged on the bottom plate, and the two back plates and the two side plates are arranged opposite to each other, and the bottom plate, the two back plates and the two side plates are arranged to form the accommodating space.

[0007] Furthermore, two ends of the driving member respectively penetrate the side plates to form an adjusting portion, and the adjusting portion drives the driving member to be rotatably disposed inside the accommodating space.

[0008] Furthermore, the driving member is provided with two groups of threads, the spiral directions of the two groups of threads are opposite, and the two fixing members are respectively connected to the two groups of threads.

[0009] Furthermore, the reset member is a spring, the reset member is sleeved on the driving member, and two ends of the reset member are respectively in contact with end surfaces of the two fixing members.

[0010] Furthermore, the stopper is a locking screw, and the stopper passes through the fixing member. The end of the stopper rotates closer to or farther away from the driving member to form an abutting state and a non-abutting state with the driving member, respectively.

[0011] Furthermore, the two opposite end faces of the fixing member are always in contact with the two opposite inner walls of the accommodating space. When the fixing members move closer to or farther away from each other, the two opposite end faces of the fixing member respectively form sliding friction with the two opposite inner walls of the accommodating space.

[0012] The technical solution adopted by the utility model to solve its technical problems is:

[0013] The beneficial effects of the utility model are:

[0014] 1. The driving member drives the two fixing members to move closer to or farther from each other along the axial direction of the driving member, thereby generating and adjusting the tensioning force along the axial direction of the driving member.

[0015] 2. Compared with the existing technical solutions, the structure of this solution is simpler and the maintenance is more indirect. While having good convenience, it can also ensure the reliability of the tensioning mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] Example:

[0025] like Figures 1 to 3 As shown, a tensioning mechanism for a velveting cleaning device comprises: an outer cover component, the outer cover component has an accommodating space 1, a driving member 2 is rotatably arranged inside the accommodating space 1, the driving member 2 is formed in a rod shape, two fixing members 3 are arranged on the driving member 2, the fixing members 3 include but are not limited to locking blocks, the driving member 2 drives the two fixing members 3 to approach each other; a reset member 4 is arranged between the two fixing members 3, the reset member 4 drives the two fixing members 3 away from each other; a stop member 5 is also arranged on the fixing member 3, the stop member 5 passes through the fixing member 3, and forms an abutting state and a non-abutting state with the driving member 2.

[0026] That is to say, the working process of the whole device can be summarized as "drive-stop-restore". The two fixing parts 3 are nested on the outside of the driving part 2, and the two fixing parts 3 are put together for a distance. Then the driving part 2 and the fixing parts 3 are placed in the accommodating space 1. A suitable position is found to rotatably set the driving part 2 in the accommodating space 1. Specifically, the driving part 2 is rotatably set on the outer cover assembly. At the same time, the driving part 2 rotates in the same direction to drive the two fixing parts 3 to approach each other (this is driving) and ensure the horizontality between the two fixing parts 3, that is, to reduce the distance between the two fixing parts 3, generate the traction pre-tension of the conveyor, and ensure the normal tension of the conveyor belt during operation by changing the tensioning degree of the conveyor belt, so as to meet the requirements of friction drive.

[0027] Furthermore, when the two fixing members 3 approach each other to a given distance, the positions of the two fixing members 3 need to be temporarily locked to ensure that the tension of the conveyor belt at a certain point in time can be maintained for a period of time. To achieve this purpose, the stop member 5 penetrates the fixing member 3 and abuts against the driving member 2, generating a large sliding friction in the axial direction of the driving member 2 (this is stopping), thereby ensuring that the two fixing members 3 are stationary relative to the driving member 2 when stopping, so that the operator can operate under a given tension.

[0028] The outer cover assembly includes a bottom plate 6, two back plates 7 and two side plates 8. The back plate 7 and the side plates 8 are both vertically arranged on the bottom plate 6, and the two back plates 7 and the two side plates 8 are arranged opposite to each other. The bottom plate 6, the two back plates 7 and the two side plates 8 are arranged to form a containing space 1.

[0029] Among them, the accommodating space 1 formed by the bottom plate 6, two back plates 7 and two side plates 8 is specifically in the shape of a long and narrow strip, and the long side direction of the accommodating space 1 can also have a certain guiding effect on the approach and distance between the fixing members 3, thereby ensuring the reliability of the tensioning force generated by the fixing members 3 during the movement.

[0030] Two ends of the driving member 2 respectively penetrate the side plates 8 to form an adjusting portion 9 . The adjusting portion 9 drives the driving member 2 to be rotatably disposed inside the accommodating space 1 .

[0031] The adjusting part 9 is specifically an adjusting knob, which is integrally connected to the driving member 2. The adjusting part 9 extends out of the outer end surface of the outer cover assembly to facilitate the operator to manually rotate the adjusting part 9, and the adjusting part 9 serves as a power source for the rotation of the driving member 2. When the adjusting part 9 is manually rotated, the driving member 2 is driven to rotate, thereby controlling the approach between the two fixing members 3.

[0032] The driving member 2 is provided with two sets of threads 10 , the spiral directions of the two sets of threads 10 are opposite, and the two fixing members 3 are connected to the two sets of threads 10 respectively.

[0033] That is to say, when the driving member 2 rotates in one direction, the threads 10 on the driving member 2 will tend to move toward or away from each other along the axial direction of the driving member 2. When the two fixing members 3 are respectively arranged on the two groups of threads 10, the driving member 2 will drive the fixing members 3 to move toward each other in a certain rotation direction, thereby generating the normal tension required for friction drive.

[0034] The reset member 4 is a spring, and is sleeved on the driving member 2 . Two ends of the reset member 4 abut against end surfaces of the two fixing members 3 , respectively.

[0035] The driving member 2 drives the two fixing members 3 to move toward each other. At this time, the reset member 4 is in a state of continuous compression during the movement toward each other of the two fixing members 3, and generates a tendency to drive the two fixing members 3 to move away from each other. When the movement toward each other of the two fixing members 3 meets the tension requirement, the manual rotation of the adjusting portion 9 is stopped, and the two fixing members 3 stop moving toward each other. At this time, the reset member 4 starts to rebound (this is reset), driving the two fixing members 3 abutting against the two ends of the reset member 4 to move away from each other, and driving the two fixing members 3 to return to the position before the movement toward each other, thereby realizing the reset of the entire device.

[0036] The stopper 5 is a locking screw. The stopper 5 passes through the fixing member 3. The end of the stopper 5 rotates to move closer to or away from the driving member 2, thereby forming an abutting state and a non-abutting state with the driving member 2, respectively.

[0037] The two opposite end surfaces of the fixing member 3 always fit with the two opposite inner walls of the accommodating space 1 . When the fixing members 3 move closer to or farther away from each other, the two opposite end surfaces of the fixing member 3 form sliding friction with the two opposite inner walls of the accommodating space 1 .

[0038] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
