Detailed Implementation

[0022] To make the technical problems solved, the technical solutions and the beneficial effects of the utility model clearer, the utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] The embodiments provided by this utility model are as follows: Figures 1-3 As shown, a cutting device for producing thermal insulation cotton includes a base 10, a rotating arm 20 rotatably connected to the base 10, a cutting assembly 30 mounted on the rotating arm 20, and a blade holder 31 rotatably connected to the rotating arm 20. A downward-facing cutting blade 32 is vertically fixed on the blade holder 31. Stretching plates 33 are mirror images of the left and right sides of the cutting blade 32. A first connecting shaft 34 is fixedly mounted on the top of the stretching plates 33. The first connecting shaft 34 is rotatably mounted on the blade holder 32 around its own axis. On the frame 31, the first connecting shaft 34 is parallel to the cutting blade 32. The bottom of the tension plate 33 is fixedly provided with a tension tilting foot 35, which is at an angle to the horizontal plane. The bottom height of the cutting blade 32 is greater than the bottom height of the tension tilting foot 35 when it is not under force. The base 10 is provided with a fixed base 40 on one side near the cutting assembly 30. The cutting table 50 is fixedly provided on the base 40. Clamping assemblies 60 are provided on both sides of the cutting table 50. The clamping assemblies 60 are used to clamp the insulation cotton on the cutting table 50.

[0024] In use, the operator places the insulation cotton on the cutting table 50, rotates the clamping assembly 60 to clamp the insulation cotton, rotates the rotating arm 20, and the rotating arm 20 drives the blade holder 31 to move closer to the cutting table 50. The stretching foot 35 contacts the insulation cotton. Then, the rotating arm 20 continues to rotate towards the cutting table 50, and the first connecting shaft 34 rotates, which in turn drives the stretching plate 33 to rotate outward. The stretching plate 33 drives the stretching foot 35 to stretch the insulation cotton, so that the insulation cotton is in a taut state. The cutting blade 32 cuts the insulation cotton, completing the cutting process of the insulation cotton. The operator then rotates the rotating arm 20 in the opposite direction, and the rotating arm 20 drives the cutting blade 32 and the stretching plate 33 to disengage from the cutting table 50, completing the reset.

[0025] Preferably, the clamping assembly 60 includes a clamping seat 61, which is fixedly mounted on the base 40. A clamping plate 62 is rotatably connected to the clamping seat 61, and the clamping plate 62 can contact the top of the cutting table 50.

[0026] Preferably, the top of the clamp 61 is provided with a second connecting shaft 63 that rotates around its own axis, and the second connecting shaft 63 is fixedly connected to the clamp 62.

[0027] Preferably, an anti-slip layer 64 is fixedly provided at the bottom of the clamping plate 62. By providing the anti-slip layer 64, the friction between the clamping plate 62 and the insulation cotton can be increased, preventing the insulation cotton from moving during the cutting process.

[0028] Preferably, an outward-facing handle 65 is fixedly connected to the second connecting shaft 63. The operator can control the handle 65 to rotate the clamp 62, making it easier to use.

[0029] Preferably, a rotating shaft 70 is horizontally fixed on the rotating arm 20, and a drive assembly that drives the rotating shaft 70 to rotate around its own axis is provided on the base 10.

[0030] Preferably, a connecting rod 36 is fixedly installed on the blade holder 31, and rolling bearings are fixedly sleeved on both sides of the connecting rod 36. The rolling bearings are snapped onto the rotating arm 20, and a drive assembly for driving the connecting rod 36 to rotate is installed on the rotating arm 20. This arrangement allows the operator to freely adjust the cutting angle of the cutting blade 32 to meet different cutting needs.

[0031] Preferably, baffles 80 are fixedly installed on the front and rear sides of the top of the base 40. On the one hand, the baffles 80 can further restrict the position of the insulation cotton, and on the other hand, the baffles 80 can prevent cutting debris from falling to the ground.

[0032] Preferably, a number of mounting columns 90 are fixedly provided on the top of the base 40, and the cutting table 50 is fixed on the mounting columns 90. By setting the mounting columns 90, it is convenient to install and replace the cutting table 50 to accommodate insulation cotton of different shapes and sizes.

[0033] Preferably, a cutting plate 100 is installed on the top of the cutting table 50. The cutting plate 100 covers the cutting table 50 and protects the cutting table 50, preventing the cutting blade 32 from damaging the cutting table 50.

[0034] The working principle of this embodiment, and its more specific process, are as follows:

[0035] The worker places the insulation cotton on the cutting table 50 and turns the handle 65. The handle 65 drives the clamping plate 62 to rotate downwards via the second connecting shaft 63, clamping the insulation cotton. The worker controls the drive assembly to operate, and the drive assembly on the base 10 drives the rotating arm 20 to rotate. The rotating arm 20 drives the blade holder 31 to move closer to the cutting table 50. The drive assembly on the rotating arm 20 drives the connecting rod 36 to rotate, and the connecting rod 36 drives the blade holder 31 to rotate to a suitable cutting position. The stretching foot 35 contacts the insulation cotton. Then, the rotating arm 20 continues to rotate towards the cutting table 50, and the first connecting shaft 34 rotates, which in turn drives the stretching plate 33 to rotate outwards. The stretching plate 33 drives the stretching foot 35 to stretch the insulation cotton, making the insulation cotton taut. The cutting blade 32 cuts the insulation cotton, completing the cutting process. The worker then turns the rotating arm 20 in the opposite direction, and the rotating arm 20 drives the cutting blade 32 and the stretching plate 33 to disengage from the cutting table 50, completing the reset.

[0036] It should be noted that when selecting and installing the cutting blade 32, the horizontal height of the cutting blade 32 should be slightly higher than that of the stretching foot 35. If the cutting blade 32 is too high, it may damage the insulation cotton when the stretching foot 35 stretches the insulation cotton.

[0037] The cutting device for producing thermal insulation cotton of this utility model has a cutting component 30 set on a rotating arm 20, a blade holder 31 rotatably connected to the rotating arm 20, a downward cutting blade 32 vertically fixed on the blade holder 31, a stretching plate 33 mirrored on the left and right sides of the cutting blade 32, a first connecting shaft 34 fixedly set on the top of the stretching plate 33, the first connecting shaft 34 rotatably set on the blade holder 31 around its own axis, a stretching tilting foot 35 fixedly set on the bottom of the stretching plate 33, the stretching tilting foot 35 forming an angle with the horizontal plane, and a cutting table 50 fixedly set on the base 40, with clamping components 60 set on both sides of the cutting table 50. This allows the cutting device for producing thermal insulation cotton to keep the part of the thermal insulation cotton to be cut in a taut state before cutting, ensuring that the cutting of the thermal insulation cotton is flat and smooth.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model shall fall within the protection scope of the present utility model.
