This structure can radially constrain each soft pearl cotton strip, fundamentally solving the problems of lateral displacement, warping, and entanglement caused by the loss of overall tension after slitting.

Description

Technical Field

[0001] This utility model particularly relates to a pearl cotton slitting device. Background Technology

[0002] EPE foam (polyethylene foam) is a cushioning packaging material that often needs to be cut into specific widths during production. Existing EPE foam cutting devices typically include a conveying mechanism and a rotary cutter. After being cut, multiple EPE foam strips entering the downstream conveying mechanism are prone to lateral shifting, warping, and even tangling due to loss of overall tension and the effects of cutting stress. Existing equipment attempts to add fixed guide baffles to prevent EPE foam deviation, but this integrated structure cannot adapt to different cutting widths and numbers of strips, resulting in poor flexibility.

[0003] Secondly, the slitting process generates a large amount of debris and dust. If this waste is not removed in time, it will accumulate inside the equipment, especially under the conveyor mechanism. Because the pearl cotton debris is fluffy and elastic, it easily hooks and supports itself at the discharge port of traditional fixed receiving plates or simple screens, forming a stable "bridging" phenomenon. This "bridging" can completely block the discharge channel, preventing subsequent debris from passing through normally. Frequent manual intervention is required for cleaning, which not only increases maintenance costs, but the accumulated debris may also be drawn into the transmission components, affecting the equipment's lifespan and posing safety hazards.

[0018] A pearl cotton slitting device includes a frame 1, a conveying assembly, a cutting assembly, an anti-deviation cover 4, and a waste collection assembly. The conveying assembly is mounted on the frame 1 and consists of a first conveying mechanism 21 and a second conveying mechanism 22 arranged in parallel along the feeding direction. The cutting assembly spans the gap between the first conveying mechanism 21 and the second conveying mechanism 22 and includes a cutter shaft 31 rotatably supported on the frame 1 and a plurality of disc cutters 32 spaced apart along the axial direction of the cutter shaft 31. The anti-deviation cover 4 is fixed on the frame 1 and located on the discharge side of the cutting assembly. A plurality of independent guide lips 41 are arranged side by side at the bottom of the anti-deviation cover 4, and an independent guide channel for constraining a single pearl cotton strip is formed between adjacent guide lips 41. The waste collection assembly includes a screen plate 51 disposed below the conveying assembly, a guide trough 52 inclinedly connected below the screen plate 51, and a collection box 53 disposed at the discharge end of the guide trough 52.

[0019] Furthermore, a vibration mechanism is provided between the sieve plate 51 and the frame 1; the vibration mechanism includes symmetrically opened slide grooves 61 on the frame 1, and sliders 62 that slide and cooperate with the slide grooves 61 are provided on both sides of the sieve plate 51; the sieve plate 51 is connected to a linear drive member 63 that drives it to reciprocate along the slide grooves 61; an elastic component is provided at the end of the slide grooves 61, and the sieve plate 51 vibrates when the sliders 62 strike the elastic component.

[0020] Furthermore, the linear drive 63 is a telescopic motor.

[0021] Furthermore, the elastic component includes a mounting post 71 fixedly disposed at the end of the slide groove 61, a spring 72 sleeved on the mounting post 71, and an abutment block 73 disposed at the end of the spring 72.

[0022] Furthermore, both the first conveying mechanism 21 and the second conveying mechanism 22 are conveyor belt mechanisms.

[0023] Furthermore, the guide lip plate 41 is detachably installed on the bottom of the anti-deviation cover 4 by means of bolt connection or snap connection.

[0024] On the worktable of frame 1, a first conveying mechanism 21 and a second conveying mechanism 22 are sequentially installed along the feeding direction. In this embodiment, both adopt a standard conveyor belt mechanism, including a driving roller, a driven roller, a conveyor belt tensioned thereon, and a drive motor. Directly above the gap between the first conveying mechanism 21 and the second conveying mechanism 22, a cutter shaft 31 is rotatably supported by a pair of bearing seats. This cutter shaft 31 is driven by a servo motor. Along the axial direction of the cutter shaft 31, three disc cutters 32 are installed at equal intervals according to the required cutting width. Directly below the conveying assembly, a waste collection assembly is provided. A screen plate 51 with screen holes is formed in sliding engagement with two symmetrically machined grooves 61 on frame 1 through sliders 62 welded on both sides. The cylinder of a telescopic motor is fixed on frame 1, and the end of its push rod is hinged to the bottom of the screen plate 51. An elastic component is installed at the end of each groove 61. The elastic component includes a mounting post 71 fixed to the bottom of the trough, a pressure spring 72 sleeved on the mounting post 71, and an abutment block 73 connected to the end of the spring 72. When the slider 62 impacts the abutment block 73, it compresses the spring 72 to absorb and store energy; subsequently, the spring 72 releases its elastic potential energy, which, through the abutment block 73, bounces the screen plate 51 in the opposite direction. Under the combined action of this impact and rebound, the screen plate 51 vibrates, thereby effectively shaking off the debris. A stainless steel guide trough 52 is installed obliquely below the screen plate 51, with its high end located below the screen plate 51 and its low end suspended above a pull-out collection box 53.

[0025] Based on the above technical solution, this utility model effectively solves the problem of bridging and clogging that easily occurs during the collection of fluffy pearl cotton debris by setting a sieve plate 51 driven by a vibration mechanism. The vibration of the sieve plate 51 can actively disrupt the stable structure between the debris, ensuring that it falls loosely and evenly into the guide trough 52.

[0026] Based on the above technical solution, this application provides four detachable guide lip plates 41 at the bottom of the anti-deviation cover 4. These guide lip plates 41 are installed side by side on the anti-deviation cover 4 by means of bolt connection or other methods, and the spacing between them can be adjusted according to the cutting width. A guide channel is formed between every two adjacent guide lip plates 41. Since four guide lip plates 41 are installed, a total of three guide channels are formed. These three channels are aligned with and accommodate the three cut pearl cotton strips, achieving personalized and precise guidance.

[0027] The equipment is started, and the first and second conveying mechanisms 22 and the cutter shaft 31 begin to operate. Wide-width EPE foam rolls are guided onto the first conveying mechanism 21, where the EPE foam is smoothly conveyed and cut into three strips by the disc cutter 32. The three strips of EPE foam then enter three independent guide channels formed by four guide lip plates 41, and under the constraint of these channels, they transition to the second conveying mechanism 22 for further output. Simultaneously, the telescopic motor pushes the screen plate 51 to slide back and forth within the chute 61. Each time the slider 62 on the screen plate 51 strikes the abutment block 73, the screen plate 51 vibrates. This vibration loosens the EPE foam debris accumulated on the screen plate 51, allowing it to fall through the screen holes into the guide chute 52 below. The debris slides along the inclined guide chute 52 into the collection box 53, achieving automatic waste removal during the production process.

[0028] This invention utilizes multiple independent guide lip plates 41 located at the bottom of the anti-deviation cover 4 to form independent guide channels corresponding to the slit pearl cotton strips in pairs. This structure can radially constrain each soft pearl cotton strip, fundamentally solving the problems of lateral displacement, warping, and entanglement caused by the loss of overall tension in the slit material. In addition, the waste collection assembly, consisting of a sieve plate 51, a vibration mechanism, an inclined guide chute 52, and a collection box 53, enables the automatic collection and removal of cutting debris and dust.

[0029] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art that various changes or modifications can be made to the present invention without departing from the principles and spirit of the present invention as defined by the claims. Therefore, the detailed description of the embodiments in this disclosure is for explanation only and not for limiting the present invention, but rather the scope of protection is defined by the content of the claims.
