[0018] The utility model is further illustrated in conjunction with the drawings and specific embodiments.

[0019] Referring to Figure 1 and Figure 2 The embodiment provides a bidirectional double-blade flat cutting machine (hereinafter referred to as a flat cutting machine) for cutting a large-thickness foam glass into multiple glass products with moderate thickness to match the use specifications of actual application scenarios, and the large-thickness foam glass is the product to be cut.

[0020] As Figure 1 The flat cutting machine of the embodiment includes two liftable saw blade units 1 and a conveying unit 2 matched with the saw blade units 1.

[0021] The conveying unit 2 is used to carry the product to be cut and has two opposite conveying directions. The two saw blade units 1 are arranged at intervals and arranged along the long direction of the conveying unit 2. The extension direction of the saw blade 11 of the saw blade unit 1 is parallel to the width direction of the conveying unit 2. The product to be cut on the conveying unit 2 moves along the two opposite conveying directions in turn. The two saw blade units 1 correspond to the two conveying directions of the conveying unit 2 one by one, and only the saw blade height of one saw blade unit 1 corresponds to the cutting height of the product to be cut in each conveying direction.

[0022] The flat cutting machine of the embodiment further includes a rack 12 and a lifting drive assembly 13. The lifting drive assembly 13 is drivingly connected to the saw blade unit 1 to lift and lower the saw blade unit 1.

[0023] More specifically, the conveying unit 2 includes a conveying belt 21 that can convey forward and backward. Of course, in other embodiments, the conveying unit 2 can also be composed of a conveying plate, a guide rail, and a screw drive assembly for carrying the product to be cut. The conveying plate moves back and forth on the guide rail by driving the screw drive assembly.

[0024] As Figure 2 The lifting drive assembly 13 includes one driver 3, one transmission shaft 4, two guide slides 5 for fixedly connecting the corresponding saw blade units 1, respectively, and two guide columns 6 and screw nut pairs 7 perpendicular to the conveying belt 21, and the two guide slides 5, the guide columns 6, and the screw nut pairs 7 are one-to-one corresponding.

[0025] The driver 3 drives the connecting transmission shaft 4 to rotate, the transmission shaft 4 is drivingly connected with the screw rod 71 of the screw nut pair 7 to lift or lower the screw rod 71, the guide sliding seat 5 is slidably assembled to the guide column 6 through the guide sliding groove, and is fixed to the screw rod 71 through the clamping hook on the guide sliding seat 5, so that the guide sliding seat 5 and the screw rod 71 are fixedly connected, and the saw blade unit 1 is arranged to be liftable.

[0026] The embodiment adopts the saw blade unit 1 belonging to the prior art, which comprises a driving assembly containing a motor, two cutter wheels arranged at intervals, and a saw blade 11 sleeved on the two cutter wheels, which follows the movement and drives the cutter wheels to rotate through the driving assembly containing the motor to drive the saw blade 11 to move correspondingly, thereby realizing slitting or cutting of the foam glass.

[0027] In specific implementation, the two saw blade units 1 are respectively a first saw blade unit and a second saw blade unit.

[0028] The conveying belt 21, the guide column 6 and the nut 72 of the screw nut pair 7 are respectively assembled to the rack 12, and the top portions of the two guide columns 6 are fixed together through the connecting frame.

[0029] Specifically, the driver 3 is a motor, the driver 3 is fixed on the connecting frame between the two guide columns 6, the transmission shaft 4 is rotatably assembled to the connecting frame, the transmission shaft 4 is sleeved with the transmission gear 9 on the outer periphery, the driver 3 is connected with the transmission gear 9 through the transmission chain 10 to realize transmission connection with each other, and the transmission shaft 4 is connected with the screw rod 71 of the screw nut pair 7 through the speed reducer 8 to drive the screw rod 71 to move, the screw rod 71 drives the guide sliding seat 5 to lift or lower together when the screw rod 71 lifts or lowers, thereby driving the corresponding saw blade unit 1 to lift or lower, and adjusting the saw blade height of the saw blade unit 1 to match the cutting height of different products to be cut.

[0030] In use, first, the saw blade of the first saw blade unit is lowered to a height position matching the cutting height of the product to be cut, the saw blade of the second saw blade unit is raised to a height position not contacting the product to be cut, then the conveying belt 21 is moved towards the first saw blade unit, so that the product to be cut on the conveying belt 21 is moved towards the saw blade of the first saw blade unit and is cut and slit into two semi-finished products with smaller thickness by the first saw blade unit, after that, the two semi-finished products in the stacked state are driven by the conveying belt 21 to continue moving without changing the direction until completely passing below the second saw blade unit and stopping on the side away from the first saw blade unit of the second saw blade unit.

[0031] Then the saw blade of the second saw blade unit is lowered to a height position that matches the cutting height of the product to be cut, and the saw blade of the first saw blade unit is raised to a height position that does not contact the product to be cut, and then the conveyor belt 21 is moved toward the second saw blade unit, so that the product to be cut on the conveyor belt 21 is moved toward the saw blade of the second saw blade unit, and is cut and cut into three semi-finished products with smaller thickness by the second saw blade unit. After that, the three stacked semi-finished products are driven by the conveyor belt 21 and continue to move in the same direction until they completely pass under the first saw blade unit and stop at the initial position. If the three semi-finished products with smaller thickness at this time all meet the usage specifications of the actual application scenario, then these three semi-finished products with smaller thickness are glass products.

[0032] If the foam glass needs to be cut into 4 or 5 or more glass products of smaller thickness, the above processing steps can be repeated, and the final glass products that meet the use specifications can be processed without adding any additional equipment. The details will not be described here.

[0033] By arranging two liftable saw blade units 1 at intervals and arranging them along the long direction of the conveying unit 2, and the conveying unit 2 having two opposite conveying directions, a cutting production line is formed in which double saw blade units are provided on the same conveying unit 2, and the products to be cut on the conveying unit 2 are moved in turn along the two opposite conveying directions, and in each conveying direction, only one saw blade unit 1 has a saw blade height corresponding to the cutting height of the products to be cut, thereby achieving multiple back and forth cutting of the products to be cut on the same conveying unit 2, so as to effectively reduce the conveying length of the conveying unit 2. Compared with the cutting production line of the prior art, the cutting production line of this embodiment can save redundant equipment (such as conveyor belts 21 and cutting machines, etc.), so that the total length of the entire cutting production line is significantly shortened. This not only has a simple and compact structure, but also occupies a smaller area.

[0034] Further preference, such as Figure 2 As shown, the outer peripheral surface of the guide column 6 has a plurality of radially protruding limiting portions 61 arranged at intervals. The guide slide 5 can be slidably mounted on the guide column 6 and limited between two adjacent limiting portions 61 to play an anti-fouling role.

[0035] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the form and details of the present invention without departing from the spirit and scope of the present invention as defined by the appended claims, and all of these changes are within the scope of protection of the present invention.
