Description

Technical Field

[0001] This invention belongs to the field of mechanical engineering technology, specifically relating to a sponge sandwich fabric tape slicing and blanking machine. Background Technology

[0002] Sponge-insulated fabric tape is a composite functional material. It consists of a sponge as the middle layer, bonded with abrasive sandpaper or industrial scouring pads as the base layer, and then bonded with fleece as the outer layer. It is characterized by its soft texture, excellent toughness, and strong absorption capacity for liquids such as coolants and cleaning agents. The resulting sponge-insulated fabric tape slices, after being die-cut, are widely used in high-speed polishing, precision grinding, and industrial cleaning applications.

[0003] However, after the sponge-backed fabric tape is punched and cut, the slices often fail to detach automatically from the base tape residue. Currently, the industry commonly uses manual methods for peeling and separating, where operators manually peel the slices off the tape one by one. This method is not only inefficient and unsuitable for mass production, but also labor-intensive, easily leading to worker fatigue, further affecting production efficiency and product quality consistency. Summary of the Invention

[0004] The purpose of this invention is to provide a sponge sandwich fabric tape slicing and blanking machine to solve the problems existing in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a sponge sandwich fabric tape slicing and blanking machine, comprising a frame, a conveyor belt, a twin-shaft roller, a patting mechanism, and a tensioning mechanism; The tensioning mechanism is located on the front side of the frame; The striking mechanism is located at the top center of the frame; The biaxial rolls are located above the rear of the frame; The conveyor belt is located in the middle of the frame and directly below the tapping mechanism; After punching, the sponge sandwich fabric strip is configured to pass sequentially under the tensioning mechanism and the patting mechanism, and exit through the gap between the two rollers of the biaxial rollers; the biaxial rollers are used to drive the excess material of the sponge sandwich fabric strip forward, and work in conjunction with the tensioning mechanism to tighten the sponge sandwich fabric strip; the patting mechanism is used to pat the slices on the sponge sandwich fabric strip from above, causing them to separate from the excess material and fall; the falling slices fall onto the conveyor belt and are sent out by the conveyor belt.

[0006] Preferably, the tensioning mechanism consists of a front guide shaft, a rear guide shaft, and connecting rods at both ends that connect the front guide shaft and the rear guide shaft respectively; the tensioning mechanism is rotatable about the axis of the rear guide shaft; the sponge interlayer fabric tape is configured to pass through from below the front guide shaft and out from above the rear guide shaft; the installation position of the front guide shaft is lower than that of the rear guide shaft, and the sponge interlayer fabric tape passing through is tensioned by the gravity of the front guide shaft and the connecting rod itself.

[0007] Preferably, the patting mechanism includes a patting shaft, at least one patting rod, and a crank-rocker power device; the patting rod is fixedly mounted on the patting shaft; the crank-rocker power device is driven to the patting shaft to drive the patting shaft to perform reciprocating rotation, thereby causing the patting rod to swing up and down to pat the slices on the sponge interlayer fabric tape.

[0008] Preferably, the number and installation position of the striking rods are configured according to the size and distribution of the slices; the axial direction of all striking rods faces the rear of the machine.

[0009] Preferably, the crank rocker power unit includes a motor, a motor mount, a swing block, a rocker arm, and an adjusting arm; the motor is fixed to the frame via the motor mount; one end of the swing block is fixedly connected to the output shaft of the motor, and the other end is hinged to one end of the rocker arm via a bearing; the adjusting arm has multiple adjusting holes, and the other end of the rocker arm is hinged to one of the adjusting holes on the adjusting arm via a pin; the other end of the adjusting arm is fixedly connected to one end of the striking shaft.

[0010] The beneficial effects of this invention are: the invention achieves efficient and automatic detachment of punched slices by automatically beating the taut sponge interlayer fabric strip through a beating mechanism; the collection and transportation of slices are completed synchronously by a conveyor belt, replacing the traditional manual peeling method, which greatly improves production efficiency and reduces labor intensity. At the same time, the equipment has a simple and reasonable structure and operates stably and reliably. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0015] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings and preferred embodiments.

[0016] like Figure 1-4 As shown in the figure, the specific structure of the sponge sandwich fabric tape slicing and blanking machine of this embodiment is as follows: The frame 1 serves as the basic support structure for the entire equipment. It is made of welded steel profiles and provides the installation foundation for each functional component.

[0017] The conveyor belt 2 is installed in the middle of the frame 1 via pulleys and a drive motor. Its belt width is slightly larger than the size of the sponge sandwich fabric slices, and the surface is made of anti-slip material to ensure effective transport of the slices.

[0018] The biaxial roller 3 consists of two parallel rollers, precisely mounted on the rear of the frame 1 via bearing seats. The gap between the two rollers can be adjusted according to the thickness of the sponge interlayer fabric. At least one roller is connected to a drive motor to provide traction power for the fabric to move forward.

[0019] The tapping mechanism mainly includes a tapping shaft 5, tapping rods 4, and a crank-rocker power unit 11. The tapping shaft 5 is symmetrically mounted on the upper center of the frame 1 via two precision bearing seats, allowing it to reciprocate within the bearing seats. Multiple tapping rods 4 are fixed to the tapping shaft 5 at specific intervals, their installation positions corresponding to the distribution of slices on the sponge interlayer fabric. The tapping rods 4 are made of lightweight, high-strength aluminum alloy, with a flexible rubber layer wrapped around their ends, enabling effective tapping without damaging the slices.

[0020] The crank-rocker power unit 11 includes a motor 111, a motor mount 112, a swing block 113, a rocker arm 114, and an adjusting arm 115. The motor 111 is securely fixed to the side of the frame 1 via the motor mount 112, and its output shaft is rigidly connected to the swing block 113. The swing block 113 is hinged to one end of the rocker arm 114 via a rolling bearing, and the other end of the rocker arm 114 is connected to an adjusting hole on the adjusting arm 115 via a pin. The adjusting arm 115 has multiple sets of adjusting holes; by selecting different holes, the swing amplitude of the striking arm can be adjusted. The end of the adjusting arm 115 is fixedly connected to the striking shaft 5 via a key, converting the rotational motion of the motor into the reciprocating oscillation of the striking shaft.

[0021] The tensioning mechanism consists of a front guide shaft 8, a rear guide shaft 10, and connecting rods 9. The rear guide shaft 10 is mounted on the front side of the frame 1 via a hinged support, allowing the entire tensioning mechanism to rotate freely around the axis of the rear guide shaft. The front guide shaft 8 and the rear guide shaft 10 are connected by two parallel connecting rods 9 to form a frame structure. The installation position of the front guide shaft 8 is significantly lower than that of the rear guide shaft 10, utilizing its own weight to generate tension. The surfaces of both guide shafts are polished to ensure that they do not cause wear when in contact with the sponge interlayer fabric tape.

[0022] First, the tensioning mechanism is hinged to the front of the frame 1 via its rear guide shaft 10, allowing the entire assembly of the front guide shaft 8 and the rear guide shaft 10, connected by the connecting rod 9, to rotate around the rear guide shaft 10. The front guide shaft 8 and the connecting rod 9 hang naturally under gravity. The slapping shaft 5 is mounted to the middle of the frame 1 via a bearing seat. Based on the size and distribution of the slices 7 on the sponge interlayer fabric 6 to be treated, a corresponding number of slapping rods 4 are fixed to the corresponding positions on the slapping shaft 5 with their axes facing backward. Subsequently, the motor 111 of the crank rocker power unit 11 is fixed to the frame 1 via a motor seat 112, with the end of its adjusting arm 115 fixed to one end of the slapping shaft 5, thereby transmitting power to the slapping mechanism. The dual-axis roller 3 is mounted to the rear of the frame 1. Finally, the conveyor belt 2 is mounted in the middle of the frame 1, ensuring that its surface is directly below the swing trajectory of the slapping rods 4, to receive and transport the falling slices 7.

[0023] When the equipment is running, the operator guides the sponge interlayer fabric strip 6, which has completed the punching process, through the path in sequence: passing under the front guide shaft 8, then around to the top of the rear guide shaft 10, then horizontally passing under the patting shaft 5 and the patting rod 4, and finally passing out through the gap between the two rollers of the dual-axis roller 3.

[0024] When the equipment is powered on, the dual-axis roller 3 rotates at a constant speed, continuously moving the remaining material of the sponge interlayer fabric belt 6 forward. Simultaneously, the crank-rocker power unit 11 starts working, and the motor 111 converts the rotational motion into the reciprocating oscillation of the slapping shaft 5 through the swing block 113, rocker arm 114, and adjusting arm 115, thereby driving the slapping rod 4 to perform up-and-down slapping motions. The conveyor belt 2 starts synchronously.

[0025] During operation, the tensioning mechanism uses its own weight to keep the sponge interlayer fabric belt 6 taut as it passes through the striking area. The high-speed reciprocating striking rod 4 precisely strikes the slices 7, overcoming the adhesion between them and the base belt, causing them to detach. The detached slices 7 naturally fall onto the conveyor belt 2 below and are collected in the collection area, thus fully realizing the automated feeding and collection of the sponge interlayer fabric belt slices.

[0026] It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention.
