DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to more clearly understand the above-mentioned objects, features, and advantages of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0026] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification.

[0027] As Figures 1-5 shown, the present utility model provides a semi-automatic foam pre-installing machine, which includes a frame 100 and a plurality of conveying rollers 101 installed inside the frame 100 for conveying foam.

[0028] A top frame 102 is fixedly installed on the top of the frame 100. Three radar distance sensors 200 are installed on the inner wall of the top frame 102 on the feeding side of the frame 100. A PLC controller 300 electrically connected to the three radar distance sensors 200 is installed on the front side of the top frame 102. A top pressing assembly 400 for pressing the top of the foam is arranged inside the top frame 102. A side pressing assembly 500 for pressing the side of the foam is installed at the bottom of the frame 100.

[0029] In this embodiment, a driving motor 103 is installed on the front side of the frame 100. The plurality of conveying rollers 101 are in transmission connection, and any one of the conveying rollers 101 is connected to the driving motor 103.

[0030] In this embodiment, the side pressing assembly 500 includes a support table 501 fixedly installed at the bottom of the frame 100. An adjustable distance motor 502 is installed on the front side of the support table 501. A bidirectional screw 503 arranged along the width direction of the support table 501 and connected to the adjustable distance motor 502 is rotatably arranged inside the support table 501. Two screw sleeves 504 arranged at intervals along its length are threadedly connected to the bidirectional screw 503. The tops of the two screw sleeves 504 are respectively fixedly connected to two connecting plates 505 that move closer to or away from each other. A plurality of side pressing rollers 506 are rotatably arranged on the tops of the two connecting plates 505. The adjustable distance motor 502 is electrically connected to the PLC controller 300 through a wire. The PLC controller 300 causes the adjustable distance motor 502 to drive the bidirectional screw 503 to rotate, and drives the connecting plates 505 through the screw sleeves 504 to make the side pressing rollers 506 move to contact both sides of the foam to prevent deviation.

[0031] In this embodiment, the pressing assembly 400 includes a plurality of cylinders 401 installed on the top frame 102 and arranged at intervals along the length direction of the top frame 102. A top pressure rod 402 is fixedly connected between the movable ends of the plurality of cylinders 401. A plurality of uniformly distributed T-shaped connecting rods 403 are fixedly connected below the top pressure rod. Upper pressure rollers 404 are rotatably arranged at both ends of the T-shaped connecting rod 403 far from the top pressure rod. The cylinder 401 is electrically connected to the PLC controller 300 through a wire. The PLC controller 300 makes the cylinder 401 extend to push the top pressure rod 402, thereby driving the T-shaped connecting rod 403 to make the upper pressure roller 404 contact the top of the foam to prevent it from being blown off.

[0032] In this embodiment, any one of the side pressure rollers 506 can be located in the gap between two adjacent conveying rollers 101. The diameter of the upper pressure roller 404 is smaller than that of the conveying roller 101 and its position corresponds to directly above the conveying roller 101. The distance between the bottom of the top pressure rod 402 and the lowest point of the upper pressure roller 404 is greater than the height by which the side pressure roller 506 exceeds the conveying roller 101. During the movement of the upper pressure roller 404 and the side pressure roller 506, there will be no collision and interference between the two.

[0033] In this embodiment, the three radar distance sensors 200 are respectively located on the inner top wall, the front side of the inner wall, and the rear side of the inner wall of the top frame 102. The radar distance sensor 200 located on the inner top wall of the top frame 102 is electrically connected to the PLC controller 300 through a wire and is used to measure the thickness of the foam. The radar distance sensors 200 located on the front side and the rear side of the inner wall of the top frame 102 are electrically connected to the PLC controller 300 through a wire and are used to measure the width of the foam;

[0034] The width calculation formula of the foam is as follows:

[0035] D_width = D1 - D2 - D3;

[0036] Wherein, D1 is the distance between the two radar distance sensors 200 on the front and rear sides, D2 is the distance measured by the radar distance sensor 200 on the front side to the foam, D3 is the distance measured by the radar distance sensor 200 on the rear side to the foam, and D_width is the width of the foam;

[0037] The thickness calculation formula of the foam is as follows:

[0038] D_thickness = D4 - D5 - D6;

[0039] Wherein, D4 is the distance from the radar distance sensor 200 at the top to the top of the frame 100, D5 is the distance from the top of the frame 100 to the top end of the conveying roller 101, D6 is the distance measured by the radar distance sensor 200 at the top to the foam, and D_thickness is the thickness of the foam;

[0040] According to the above, the width and thickness of the foam can be calculated to facilitate the PLC controller 300 to control the stroke of the top pressing component 400 and the side pressing component 500.

[0041] In this embodiment, the radar distance sensor 200 located on the inner top wall of the top frame 102 detects downward and its position is offset from the conveying roller 101. The two radar distance sensors 200 located on the front side and the rear side of the inner wall of the top frame 102 correspond to each other in the front and rear positions and are higher than the highest point of the conveying roller 101. The three radar distance sensors 200 detect the foam, and their positions will not be affected by the conveying roller 101.

[0042] In this embodiment, both ends of the inner side of the support table 501 are fixedly connected with limit rods 507. The limit rods 507 pass through the connecting plate 505, and the connecting plate 505 slides along the length direction of the limit rods 507. The limit rods 507 are provided to limit the connecting plate 505, so that the connecting plate 505 moves linearly to overcome the circumferential rotation tendency of the screw sleeve 504.

[0043] Usage method and working principle of this device:

[0044] When this device is in use, the foam material to be conveyed is placed on the conveying roller 101, and the placement direction starts from the side with the radar distance sensor 200. The three radar distance sensors 200 in the front, rear, and above respectively detect the distance of the foam and transmit the signals to the PLC controller 300. The PLC controller 300 calculates the width and thickness of the foam and controls the cylinder 401 and the distance adjustment motor 502 to work. According to the calculated thickness of the foam, the stroke of the cylinder 401 is controlled, so that the cylinder 401 extends to push the upper pressure rod 402, thereby driving the T-shaped connecting rod 403 to make the upper pressure roller 404 contact the top of the foam to prevent it from being blown off. According to the calculated width of the foam, the distance adjustment motor 502 drives the bidirectional screw rod 503 to rotate, controls the stroke of the screw sleeve 504 moving along the bidirectional screw rod 503, and drives the connecting plate 505 under the action of the screw sleeve 504 to make the side pressure roller 506 move to contact both sides of the foam to prevent deviation;

[0045] While the foam material is being transported on the conveying roller 101, centering and limiting are performed according to the width of the foam to prevent the foam from having a tendency to shift and fall to both sides, and limiting is performed from above according to the thickness of the foam to prevent it from being blown off, facilitating the next process of the foam.

[0046] The above are only the preferred embodiments of the present utility model, and are not intended to limit the present utility model in other forms. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present utility model without departing from the content of the technical solution of the present utility model still fall within the protection scope of the technical solution of the present utility model.
