DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment

[0019] Please refer to Figures 1-4, the present utility model provides a technical solution: a filter cloth tensioning device for a vacuum filter, including a device main body 7. A tensioning roller 4 is arranged at the bottom left of the device main body 7. A filter cloth 1 is drivingly connected to the outside of the tensioning roller 4. Tensioning guide rails 5 are arranged on the front and rear end faces of the tensioning roller 4, and tensioning bearings 6 are arranged between the front and rear end faces of the tensioning roller 4 and the tensioning guide rails 5. The tensioning bearings 6 are sleeved on the outer walls of the front and rear end faces of the tensioning roller 4. Tensioning roller adjusting screw seats 3 are arranged on both sides of the front and rear end faces of the tensioning roller 4. Tensioning cylinders 2 are arranged on the front and rear end faces at the top of the tensioning roller 4. The tensioning cylinders 2, the tensioning roller adjusting screw seats 3 and the tensioning guide rails 4 form a manual mechanical adjusting device. The height of the tensioning bearing 6 is adjusted by this adjusting device, and the height of the tensioning roller 4 is adjusted through the tensioning bearing 6, thereby adjusting the tightness of the filter cloth. An electric telescopic rod 8 is arranged in the middle on the left side of the device main body 7. A tensioning adjusting rod 9 is arranged on the left side of the electric telescopic rod 8. Connecting blocks 10 are arranged in the middle of the right front and rear end faces of the tensioning adjusting rod 9. Fixed blocks 11 matched with the connecting blocks 10 are arranged on the left sides of the front and rear end faces of the electric telescopic rod 8, and bolts 12 are arranged between the connecting blocks 10 and the fixed blocks 11 on the same side. An arc-shaped contact surface 13 is arranged on the left side of the tensioning adjusting rod 9. The left side of the tensioning adjusting rod 9 is in fit connection with the filter cloth 1 through the arc-shaped contact surface 13. The electric telescopic rod 8 can fit one end of the tensioning adjusting rod 9 with the arc-shaped contact surface 13 onto the filter cloth 1 through telescoping, and then the tightness of the filter cloth 1 can be adjusted through the cooperation of the telescoping of the electric telescopic rod 8 and the tensioning adjusting rod 9.

[0020] Among them, preferably, a plurality of sets of ball grooves 14 are longitudinally arranged in parallel from the inside to the outside on the outside of the tensioning adjusting rod 9, and balls 15 are arranged in the ball grooves 14. Such a setting can not only reduce the friction between the tensioning adjusting rod 9 and the filter cloth 1, but also increase the smoothness of the filter cloth 1 passing through the tensioning adjusting rod 9.

[0021] Preferably, fixed bases matched with the tensioning guide rails 5 are arranged on the front and rear end faces at the bottom left of the device main body 7, and the tensioning guide rails 5 on the front and rear end faces are vertically and parallelly arranged on the left side of the device main body 7. The arranged fixed bases can play the role of supporting and fixing the tensioning guide rails 5.

[0022] Preferably, support plates are arranged around the bottom of the device main body 7, and mounting holes are vertically penetrated through the four weeks of the top of the support plates. The device main body 7 can be installed and fixed through the cooperation of the mounting holes and the support plates. Embodiment

[0023] Refer to Figures 1-4, what is different about this embodiment from the first embodiment is that: in the middle of the left side of the device main body 7, there is an installation groove that matches the electric telescopic rod 8. The installation of the electric telescopic rod 8 can be conveniently fixed through the provided installation groove. The included angle between the electric telescopic rod 8 and the device main body 7 is set to ninety degrees. Such a setting can increase the stability of the connection between the electric telescopic rod 8 and the device main body 7; the length of the tension adjustment rod 9 from the inside to the outside is greater than the length of the filter cloth 1 from the inside to the outside. Such a setting can comprehensively contact the filter cloth 1, thereby adjusting the tightness of the filter cloth 1.

[0024] The electrical appliances mentioned in this article are all connected to an external power source through wires.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
