Description

Technical Field

[0001] This utility model relates to the field of flooring production, and in particular to an edge trimming device for producing plastic flooring. Background Technology

[0002] Plastic flooring, also known as flooring made of plastic materials, can be classified into two types according to its usage: tiles (or floor tiles) and rolls (or linoleum). According to its material, it can be classified into three types: rigid, semi-rigid, and soft (elastic). The production of plastic flooring has length and width requirements. If the two sides of the freshly formed plastic flooring do not meet the specified size requirements, an edge trimming device is needed to trim the edges of the plastic flooring.

[0003] A search revealed Chinese Patent Publication No. CN221291400U, which discloses an edge-trimming device for PVC plastic flooring production. This patent includes a workbench with a rotating construction plate on top. An edge-trimming mechanism is located on one side of the rotating construction plate, and a linear slide is located on one side of the edge-trimming mechanism. Horizontal calibration mechanisms are located on both sides of the rotating construction plate. This device can automatically adjust the direction and angle of the measuring instrument to adapt to different conditions, thereby improving its applicability. However, current edge-trimming devices for plastic flooring production lack rapid adjustment methods for edge-trimming operations of different widths, and burrs are generated on the cut surface after trimming, requiring further processing and affecting production efficiency.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figure 1 — Figure 6As shown, a trimming device for producing plastic flooring includes a base frame 101. A trimming table 102 is bolted to the top of the base frame 101. A conveying mechanism and a driving mechanism are mounted on the base frame 101. The driving mechanism includes two upright plates 301 bolted to the sides of the base frame 101. A main shaft 302 is rotatably connected between the upright plates 301. A motor 304 is bolted to the outer side of the upright plates 301. The output shaft of the motor 304 is connected to the main shaft 302 via a coupling. Two symmetrically arranged trimming mechanisms are mounted on the main shaft 302. Each trimming mechanism includes a mounting ring 401, on which a cutting blade 402 is bolted. The cutting blade 402 is annular. The main shaft 302 has several locking holes 303. The mounting ring 401 is screwed... The mounting ring 401 is connected to a locking bolt 403 that mates with the locking hole 303. A guide plate 404 is rotatably connected to the mounting ring 401. A guide shaft 405 is slidably connected to the guide plate 404. The guide shaft 405 is bolted to the upright plate 301. A grinding mechanism is provided on the guide plate 404. The grinding mechanism includes a connecting plate 601. A groove 602 is provided on the connecting plate 601. The guide plate 404 is slidably disposed in the groove 602. A grinding component 603 is bolted to the connecting plate 601. A transmission mechanism is provided on the mounting ring 401. The transmission mechanism is disposed between the mounting ring 401 and the connecting plate 601. With the transmission mechanism, when the cutting blade 402 is performing rotary cutting, the connecting plate 601 can reciprocate back and forth, so that the grinding component 603 grinds the two cut surfaces of the plastic floor.

[0026] In this embodiment, the cutting table 102 has a second slot 104 for accommodating the grinding part 603. The grinding part 603 is C-shaped and has a grinding layer 605 on its inner side. After the plastic flooring is cut, the grinding layer 605 of the grinding part 603 will grind the two cut surfaces of the plastic flooring, eliminating the need for further processing and improving production efficiency.

[0027] In this embodiment, an inclined surface 604 is provided on the opposite side of the two grinding parts 603, and the inclined surface 604 separates the scrap material cut from the plastic flooring from the plastic flooring.

[0028] In this embodiment, the transmission mechanism includes a first bevel gear 501, which is bolted to a mounting ring 401. A second bevel gear 502 meshes with the first bevel gear 501. A connecting rod 503 is rotatably connected to the second bevel gear 502. One end of the connecting rod 503 away from the second bevel gear 502 is bolted to a guide plate 404. A reciprocating screw 504 is bolted to one end of the second bevel gear 502 away from the first bevel gear 501. A moving ring 505 is threaded onto the reciprocating screw 504. A connecting plate 601 is rotatably connected to the moving ring 505.

[0029] In this embodiment, the conveying mechanism includes two mounting frames 201, which are bolted to the top of the base frame 101. The two mounting frames 201 are respectively arranged on the front and rear sides of the trimming table 102. Several sets of conveying rollers 203 are rotatably connected inside the mounting frame 201. The surface of the conveying rollers 203 is provided with a rubber layer to prevent the plastic floor from shifting and sliding when it moves. A power assembly 202 for driving the conveying rollers 203 is bolted to the mounting frame 201.

[0030] In this embodiment, a first slot 103 is provided on the cutting table 102, and the bottom of the cutting blade 402 is located in the first slot 103. The first slot 103 allows the cutting blade 402 to move left and right, and the cutting blade 402 can ensure the cutting effect when the plastic floor moves through the position of the first slot 103.

[0031] Working Principle: When using this device, first adjust the positions of the cutting blade 402 and the grinding piece 603 according to the trimming requirements of the plastic flooring. During adjustment, rotate the locking bolt 403 to disengage it from the locking hole 303. Then, slide the two mounting rings 401 left and right to the designated positions. As the mounting rings 401 move, they drive the connecting plate 601 to move axially along the guide shaft 405 via the guide plate 404, thus synchronously changing the position of the grinding piece 603. Then, rotate the locking bolt 403 back into the locking hole 303 at that position to lock the mounting rings 401. At this point, the trimming operation of the plastic flooring can begin. Turn on the power assembly 202 and the motor 304. The power assembly 202 drives several sets of conveyor rollers 203 to rotate. The operator places the plastic flooring to be trimmed from the front of the mounting frame 201. Between the conveyor rollers 203, the plastic flooring is fed into the trimming table 102. The motor 304 drives the main shaft 302 to rotate. The main shaft 302 drives the mounting ring 401 and the cutting blade 402 to rotate synchronously through the locking bolt 403. The cutting blade 402 trims the plastic flooring. When the mounting ring 401 rotates, it drives the first bevel gear 501 to rotate synchronously. The first bevel gear 501 drives the reciprocating screw 504 to rotate through the second bevel gear 502. When the reciprocating screw 504 rotates, it drives the moving ring 505 to move back and forth. The moving ring 505 drives the connecting plate 601 to move synchronously along the length of the guide shaft 405. The connecting plate 601 drives the grinding part 603 to move back and forth on the cut surface of the plastic flooring, thereby grinding the burrs. This is how the trimming operation is performed during the production of plastic flooring.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
