Description

Technical Field

[0001] The invention relates to the technical field of sponge processing equipment, and in particular discloses a sponge thin-cutting and rolling equipment. Background Art

[0002] The sponge blocks produced by the existing sponge foaming production line are all in the form of long strips with a width of about 1.0~1.5m and a length of more than 30m. In the subsequent processing of the sponge blocks, they need to be cut according to customer needs. Some customers need to cut the sponge blocks into thin sheets for making various fixture cushions. The traditional processing method is to first cut the sponge into cylindrical shapes, and then use a sponge circular cutting machine for cutting and rolling. This processing method will produce a large amount of sponge scraps, resulting in serious waste and increased costs.

[0003] The invention patent with application number 202311512440.0 discloses a sponge cutting device, including a limit assembly, a fixing assembly, a cutting assembly and a base. The limit assembly and the fixing assembly are both arranged on the base. The limit assembly is located on both sides of the sponge for limiting the left and right positions of the sponge. The fixing assembly is located on the top of the sponge. The cutting assembly is slidably connected to the base, and its output end can be pressed down to complete the cutting of the sponge. When cutting, the sponge is placed on the base, and the sponge is fixed in the front, back, left and right directions by the limit assembly and the fixing assembly, and the cutting assembly is pressed down so that its output end contacts the sponge to complete the cutting. The cutting assembly can slide along the base to achieve cutting at different positions, so that the size of the cut sponge meets different needs. Although the cutting device disclosed in the patent realizes automatic cutting of the sponge through the cooperation of the limit assembly, the fixing assembly and the cutting assembly, the sponge cutting device cuts the sponge into long strips instead of thin slices. In addition, the sponge cutting device cannot ensure the uniform thickness of the sponge after thin cutting, nor can it roll up the cut material. An additional rolling operation is required, which increases the steps of sponge cutting processing. Therefore, in view of the shortcomings of the existing sponge cutting device that is unable to evenly slice the sponge and unable to synchronously rewind the sponge, the present application proposes a sponge thinning and rewinding device that can effectively solve the above technical problems. Summary of the invention

[0004] The present invention aims to provide a sponge thin-cutting and rolling device to achieve uniform thin-cutting of a sponge block and synchronous rolling processing.

[0005] The present invention is achieved through the following technical solutions: A sponge thin-cutting and rolling device comprises a box seat for placing a sponge block, the upper surface of the box seat is provided with a walking frame moving along the length direction of the sponge block, the walking frame is provided with a lifting and adjusting frame and a lifting and guiding assembly for driving the walking frame to move up and down, a knife frame is fixed in the lifting and adjusting frame, a cutting blade is installed at the lower end of the knife frame, a pressure roller seat is provided just above the cutting edge of the cutting blade, a pressure roller is rotatably provided in the pressure roller seat, a vertical guiding assembly is provided between the pressure roller seat and the lifting and adjusting frame, a lifting and hanging mechanism for lifting and adjusting the pressure roller seat is provided in the lifting and adjusting frame, both ends of the lifting and adjusting frame below the cutting blade are provided with centering clamps, and the two centering clamps are symmetrically arranged on both sides of the sponge block, and the centering clamps are connected to the side ends of the lifting and adjusting frame through horizontal guide rods and springs; A side plate is fixed on the lifting and adjusting frame at a side away from the cutting blade edge portion, a sheet winding roller is rotatably connected to the side plate, and a winding motor is connected to the end of the sheet winding roller.

[0006] During the thin-cutting and winding process of a sponge block, the sponge thin-cutting and winding device disclosed in the present invention first controls the operation of the lifting guide component according to the current thickness of the sponge block and the thickness required for cutting, and adjusts the lifting adjustment frame to a corresponding height under the action of the lifting guide component so that the distance between the bottom of the cutting blade and the upper surface of the sponge block is equal to the cutting thickness.

[0007] Then move the traveling frame toward one end of the sponge block, so that the cutting blade extends into the sponge block for a certain distance, and then start the lifting mechanism, and lower the pressure roller seat through the lifting mechanism, so that the pressure roller presses on the sponge block above the cutting blade, and then continue to move the traveling frame, so that while the cutting blade cuts the sponge block, the pressure on the top of the sponge block remains unchanged. At the same time, the two center clamps clamp and limit the two sides of the sponge below the cutting point under the action of the spring support force, so as to prevent the top of the sponge from convexly deforming to both sides under the pressure, thereby ensuring the uniformity of sponge cutting.

[0008] In addition, during the movement of the traveling frame, the winding motor is started to rotate the film winding roller, and the cut sponge film is synchronously wound up by the film winding roller until the entire traveling frame moves out from the other end of the sponge block, indicating that one cutting and winding is completed. Finally, the operator removes the sponge film roll from the film winding roller, and then moves the traveling frame back to reset it. After adjusting the height position of the cutting blade again, the next cutting and winding action can be performed.

[0009] As a further configuration of the above scheme, the vertical guide assembly includes convex plates arranged on the inner walls of both sides of the lifting and adjusting frame, the convex plates are provided with guide cylinders, and both ends of the pressure roller seat are provided with guide rods penetrating the corresponding guide cylinders. The above is a specific design scheme of the vertical guide assembly, and the action between the guide cylinder and the guide rod can ensure that the pressure roller is vertically pressed on the upper surface of the sponge block, and ensure that the part of the sponge block that contacts the pressure roller is evenly stressed.

[0010] As a further configuration of the above scheme, the lifting mechanism includes a rotating shaft rotatably arranged in a lifting and adjusting frame above the pressure roller seat, and the end of the rotating shaft is connected to a driving device, and a winding wheel is arranged on the rotating shaft, and a connecting rope whose lower end is connected to the pressure roller seat is wound around the winding wheel. The above is a specific design scheme of the lifting mechanism, which drives the rotating shaft to rotate through the driving device, and then the pressure roller is lifted up and down under the action of the winding wheel and the connecting rope, and the weight of the pressure wheel can be fully applied to the upper surface of the sponge block, ensuring that the upper surface of the sponge block is evenly stressed during the movement.

[0011] As a further configuration of the above scheme, vertical slide grooves are provided on the opposite surfaces of both sides of the walking frame, the lifting guide assembly includes a slide rod and a screw rod respectively arranged in the two vertical slide grooves, and a screw motor connected to the screw rod is arranged on the top of the gantry body, and a sliding hole block and a screw hole block acting with the slide rod and the screw rod are respectively arranged on both side ends of the lifting adjustment frame. The above is a specific design scheme of the lifting guide assembly, and the height of the lifting adjustment frame can be adjusted in real time through the action between the screw motor, the screw rod and the screw hole block.

[0012] As a further configuration of the above scheme, a laser distance sensor facing the lifting and adjusting frame is installed on the top of the traveling frame, and the laser distance sensor and the lead screw motor are electrically connected to a controller. The laser distance sensor can monitor the height position of the lifting and adjusting frame in real time, and control it in real time through the controller, thereby realizing precise adjustment of the height of the cutting blade position.

[0013] As a further configuration of the above scheme, the upper surface of the box seat is provided with mutually parallel slide rails and roller grooves, the walking frame includes a gantry frame body, the lower end of the gantry frame body is provided with a wheel seat, the wheel seat is provided with rollers that rotate and interact with the roller grooves, and a slide groove opening that interacts with the slide rails is provided, and the wheel seat is provided with a walking motor that drives the rollers. A specific scheme of the walking mechanism between the walking frame and the box seat is that the walking frame can stably move along the length direction of the upper surface of the box seat through the driving action of the rollers and the guiding action of the slide rails.

[0014] As a further configuration of the above scheme, the two centering clamps are symmetrically arranged in an "eight" shape on both sides of the lower end of the lifting and adjusting frame, the spring is connected between the centering clamp and the lifting and adjusting frame, and the horizontal guide rod is connected to the centering clamp and is arranged through the through hole on the side end of the lifting and adjusting frame. The position design of the two centering clamps can enable the centering clamp to always clamp and limit the sponge block under the cutting blade, so as to prevent the sponge block from protruding and deforming to both sides and affecting the final thin cutting uniformity.

[0015] As a further configuration of the above scheme, a weight plate sleeve rod is provided at the center of the upper surface of the pressure roller seat, and a plurality of weight plates are provided on the weight plate sleeve rod. Through the above further configuration of the pressure roller seat, when thin slices are cut for sponge blocks with different foaming effects, the force applied by the pressure roller on the sponge block can be adjusted so that different sponge blocks can be thinly sliced ​​uniformly.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The sponge thin-cutting and winding device disclosed in the present invention utilizes a traveling frame to move linearly along the upper surface of a box seat, and then completes the thickness cutting of the sponge block through the action of a cutting blade during its linear movement, and can perform online winding of the cut sponge slices through a winding roller during the mobile cutting process, which not only realizes the efficient cutting of the sponge slices, but also realizes automatic winding and packaging, greatly improving the cutting and processing efficiency of the sponge block.

[0017] The sponge thin-cutting and winding device disclosed in the present invention can also press the pressure roller on the upper surface of the sponge block directly above the cutting blade during operation. During the moving cutting process, the force on the upper surface of the sponge block always remains consistent. Combined with the clamping and limiting effect of the center clamping plates on both sides of the sponge block, the sponge block can be evenly cut during the fixed-thickness thin-cutting process, and the thickness of the cut sponge slices can be kept uniform, which greatly improves the cutting effect of the sponge slices.
