Description

一种低压大截面单芯电缆弯曲装置及其使用方法A low-voltage large-section single-core cable bending device and use method thereof

技术领域Technical Field

本发明涉及弯曲设备的技术领域,特别是涉及一种低压大截面单芯电缆弯曲装置及其使用方法。The invention relates to the technical field of bending equipment, and in particular to a low-voltage large-section single-core cable bending device and a use method thereof.

背景技术Background Art

低压大截面单芯电缆是指用于低压配电系统中,具有较大导体截面积的单芯电缆,这类电缆的设计主要用于传输较低电压等级(通常指工频额定电压0.6/1kV及以下)的电力,同时因为其较大的导体截面积(如240mm²、调径单元(300)mm²、动力单元(400)mm²等),能够承载较高的电流负荷,适合远距离输电或是对电流容量有较高要求的场合。Low-voltage large-section single-core cable refers to a single-core cable with a larger conductor cross-sectional area used in low-voltage power distribution systems. This type of cable is designed mainly for transmitting power at lower voltage levels (usually referring to the rated power frequency voltage of 0.6/1kV and below). At the same time, due to its larger conductor cross-sectional area (such as 240mm², adjustable diameter unit (300) mm², power unit (400) mm², etc.), it can carry a higher current load and is suitable for long-distance power transmission or occasions with high requirements for current capacity.

电缆在架设时,经常会遇到如狭小空间、管道转弯处、电缆桥架的转角等特殊位置,电缆在该位置一般需要进行弯曲处理,常用的电缆弯曲方式是通过两个推柱抵在电缆一侧,再利用两个推柱中间的顶柱对电缆另一侧进行挤压,从而使电缆弯曲,而采用该弯曲方式时,弯曲的电缆会形成一定角度,即电缆弯曲位置无法形成弧形,电缆弯曲位置的弧度较小,这样容易造成电缆应力集中或因弯曲局部区域的变形量过大而导致电缆电芯断裂,影响电缆正常使用。When laying cables, they often encounter special locations such as narrow spaces, pipe bends, and corners of cable trays. Cables generally need to be bent at these locations. The commonly used cable bending method is to use two push columns to push against one side of the cable, and then use the top column between the two push columns to squeeze the other side of the cable to bend the cable. When this bending method is used, the bent cable will form a certain angle, that is, the cable bending position cannot form an arc, and the arc at the cable bending position is small, which can easily cause cable stress concentration or cause cable core breakage due to excessive deformation in the local bending area, affecting the normal use of the cable.

The conical surface 204 can position the multiple single plates 201 in an arc arrangement, so that the multiple single plates 201 can switch between a straight line arrangement and an arc arrangement. When the multiple single plates 201 are arranged in a straight line, the cable can be placed on the clamping unit on the multiple single plates 201. When the single boards 201 are deformed into an arc-shaped arrangement, the cable is bent into an arc shape. Since the position of the first single board 201 among the multiple single boards 201 is fixed and the remaining multiple single boards 201 can move, the specific number of movements of the multiple single boards 201 can determine the arc of the cable bending, that is, the cable bending angle, and the number of movements of the multiple single boards 201 is calculated starting from the first single board 201, and the position of the stage 205 on the single board 201 can determine the distance between the clamping unit and the center of the circle where the multiple single boards 201 arranged in an arc shape are located, that is, the bending radius of the cable, thereby realizing the adjustment of the specific situation of the cable bending.

在实际使用时,缠绕有电缆的线盘一边移动,一边释放电缆,线盘可采用车载等方式移动,释放的电缆不再移动,当线盘移动至需要弯曲电缆的位置时,将电缆放置在多个单板201上的夹持单元上,利用动力单元400推动多个单板201移动并变形的方式对电缆进行弯曲即可,而为了方便弯曲装置移动,可在底座100底部配套加装支腿和滚轮等常规结构。In actual use, the cable drum wrapped with the cable moves while releasing the cable. The cable drum can be moved by means of a vehicle or the like. The released cable no longer moves. When the cable drum moves to the position where the cable needs to be bent, the cable is placed on the clamping units on the multiple single boards 201. The power unit 400 is used to push the multiple single boards 201 to move and deform, so as to bend the cable. In order to facilitate the movement of the bending device, conventional structures such as legs and rollers can be installed at the bottom of the base 100.

由于电缆截面面积较大,电缆重量较大,因此释放的电缆不宜再次移动,只能对电缆进行静态弯曲处理,传统方式中利用电缆在三个呈三角形分布的滚轮之间进行弧形滚压的方式难度较大,不宜采用。Due to the large cross-sectional area and heavy weight of the cable, the released cable should not be moved again and can only be subjected to static bending. The traditional method of using the cable to perform arc rolling between three rollers distributed in a triangle is difficult and should not be used.

通过弯曲单元200的创新设计,尤其是单板201可转动和直线/弧形排列方式切换功能,以及载物台205在单板201上的可调位置设计,实现了对电缆弯曲半径和弯曲弧度的精确调节,这有助于避免电缆因过度弯曲或不恰当的弯曲形态导致的应力集中和电芯损伤,提高了电缆使用的安全性和可靠性;该装置能够根据实际需求灵活调整电缆的弯曲程度,无论是需要较小的弯曲角度还是较大的弯曲半径,都能通过调整单板201的数量和载物台205的位置来实现,适用于不同安装环境下的电缆铺设需求,特别是在狭小空间或需要特定角度转弯的复杂布局中;该装置结构简单,电缆变形方式简便,降低了操作难度;综上所述,该发明不仅提升了电缆弯曲作业的精确度和效率,还显著增强了电缆的安全使用和维护便利性,是针对低压大截面单芯电缆铺设难题的一项重要技术创新。Through the innovative design of the bending unit 200, especially the rotatable and straight/arc arrangement switching functions of the single plate 201, and the adjustable position design of the stage 205 on the single plate 201, precise adjustment of the cable bending radius and bending curvature is achieved, which helps to avoid stress concentration and cell damage caused by excessive bending or inappropriate bending shape of the cable, and improves the safety and reliability of cable use; the device can flexibly adjust the bending degree of the cable according to actual needs, whether a smaller bending angle or a larger bending radius is required, it can be achieved by adjusting the number of single plates 201 and the position of the stage 205, which is suitable for cable laying needs in different installation environments, especially in small spaces or complex layouts that require turning at specific angles; the device has a simple structure, a simple cable deformation method, and reduces the difficulty of operation; in summary, the invention not only improves the accuracy and efficiency of cable bending operations, but also significantly enhances the safe use and maintenance convenience of cables. It is an important technical innovation for the difficult problem of laying low-voltage large-section single-core cables.

如图4至图5所示,所述载物台205的前后两侧均设置有导向板206,导向板206的一端水平滑动安装在载物台205侧壁上,导向板206的另一端垂直穿过单板201并相对滑动,导向板206与单板201之间通过弹片207连接;As shown in FIGS. 4 and 5 , guide plates 206 are provided on both the front and rear sides of the stage 205. One end of the guide plate 206 is horizontally slidably mounted on the side wall of the stage 205. The other end of the guide plate 206 vertically passes through the single board 201 and slides relatively. The guide plate 206 and the single board 201 are connected by a spring sheet 207.

其中,所述单板201上开设滑槽,滑槽内设置卡齿,载物台205滑动安装在滑槽内,载物台205上设置卡齿,滑槽内的卡齿与载物台205上的卡齿啮合。The single board 201 has a slide groove, a latching tooth is arranged in the slide groove, the loading platform 205 is slidably installed in the slide groove, a latching tooth is arranged on the loading platform 205, and the latching tooth in the slide groove meshes with the latching tooth on the loading platform 205.

详细的,通过设置卡齿使单板201与载物台205卡装连接,可对载物台205在单板201上的位置进行自动锁定,避免电缆弯曲时,载物台205在单板201上移动,利用弹片207和导向板206对载物台205的弹性下拉力,可使载物台205牢固的卡在单板201上,当需要调节载物台205在单板201上的位置时,只需提升载物台205,使载物台205与单板201脱齿,之后使载物台205在滑槽内滑动即可,此时载物台205与导向板206相对滑动,导向板206始终为载物台205提供向下弹性拉力,当调节完成后,松开载物台205,弹片207可拉动载物台205重新卡在单板201上,该结构方式即实现了锁定功能,又能够满足载物台205位置调节的需求。In detail, by setting the latch teeth to make the single board 201 and the loading platform 205 snap-fitted and connected, the position of the loading platform 205 on the single board 201 can be automatically locked to prevent the loading platform 205 from moving on the single board 201 when the cable is bent. The elastic downward pulling force of the spring sheet 207 and the guide plate 206 on the loading platform 205 can make the loading platform 205 firmly stuck on the single board 201. When the position of the loading platform 205 on the single board 201 needs to be adjusted, it is only necessary to lift the loading platform. 205, so that the stage 205 and the single board 201 are disengaged, and then the stage 205 can be slid in the slide groove. At this time, the stage 205 and the guide plate 206 slide relatively, and the guide plate 206 always provides a downward elastic pulling force for the stage 205. When the adjustment is completed, the stage 205 is released, and the spring piece 207 can pull the stage 205 to be stuck on the single board 201 again. This structural method realizes the locking function and can meet the needs of position adjustment of the stage 205.

如图6所示,所述夹持单元包括在载物台205上相对设置的两个直角座208,每个直角座208上均竖向滑动设有直角架209,直角座208与直角架209之间通过弹性板210连接,弹性板210上转动设置有多个圆柱形的橡胶囊211。As shown in Figure 6, the clamping unit includes two right-angle seats 208 arranged opposite to each other on the stage 205, each right-angle seat 208 is provided with a vertically slidable right-angle frame 209, the right-angle seat 208 and the right-angle frame 209 are connected by an elastic plate 210, and a plurality of cylindrical rubber bags 211 are rotatably provided on the elastic plate 210.

详细的,橡胶囊211内可填充空气或液体,弹性板210能够发生弹性变形,在自然状态时,弹性板210推动直角架209和直角座208之间形成最大距离的开口。In detail, the rubber bag 211 can be filled with air or liquid, and the elastic plate 210 can be elastically deformed. In the natural state, the elastic plate 210 pushes the right-angle frame 209 and the right-angle seat 208 to form an opening with a maximum distance.

一个直角座208固定在载物台205上,另一个直角座208能够在载物台205上移动,当需要对电缆进行夹持时,将电缆放置在两个直角座208之间,推动能够在载物台205上移动的直角座208移动,两个直角座208相互靠近,直角座208上的多个橡胶囊211对电缆外壁进行挤压固定处理,同时由于电缆的反向挤压,弹性板210发生弧形变形,从而使其上的多个橡胶囊211都能够与电缆接触,提高电缆受力面积,由于弹性板210的变形,直角架209在直角座208上滑动,橡胶囊211受到电缆的反向挤压,橡胶囊211与电缆之间存在较大接触面积,由此使橡胶囊211为电缆起到缓冲保护的作用,同时在电缆弯曲时,由于电缆变形,其与夹持单元之间会发生相对运动,此时电缆会带动橡胶囊211在弹性板210上转动,从而使电缆能够平稳弯曲。One right-angle seat 208 is fixed on the stage 205, and the other right-angle seat 208 can move on the stage 205. When the cable needs to be clamped, the cable is placed between the two right-angle seats 208, and the right-angle seat 208 that can move on the stage 205 is pushed to move. The two right-angle seats 208 are close to each other, and the multiple rubber bags 211 on the right-angle seats 208 squeeze and fix the outer wall of the cable. At the same time, due to the reverse squeezing of the cable, the elastic plate 210 is deformed in an arc shape, so that the multiple rubber bags 211 on it are 11 can contact with the cable, thereby increasing the force-bearing area of the cable. Due to the deformation of the elastic plate 210, the right-angle frame 209 slides on the right-angle seat 208, and the rubber bag 211 is reversely squeezed by the cable. There is a large contact area between the rubber bag 211 and the cable, thereby enabling the rubber bag 211 to play a buffering and protective role for the cable. At the same time, when the cable is bent, due to the deformation of the cable, relative movement will occur between it and the clamping unit. At this time, the cable will drive the rubber bag 211 to rotate on the elastic plate 210, so that the cable can be bent smoothly.

如图6至图7所示,所述夹持单元还包括套管212和插杆213,套管212固定在一个直角座208上,插杆213穿过另一个直角座208并相对转动,插杆213的一端设置有扳手214,插杆213的另一端滑动插入套管212内;As shown in FIGS. 6 and 7 , the clamping unit further includes a sleeve 212 and an insertion rod 213. The sleeve 212 is fixed on one right-angle seat 208. The insertion rod 213 passes through another right-angle seat 208 and rotates relatively. A wrench 214 is provided at one end of the insertion rod 213. The other end of the insertion rod 213 is slidably inserted into the sleeve 212.

其中,套管212内壁上和插杆213外壁上均设置有凸齿215,插杆213的外壁上还设置有凹陷区216,当插杆213转动并使其上凸齿215与套管212内的凸齿215啮合时,套管212与插杆213之间位置锁定,此时扳手214倾斜搭接在载物台205上,当插杆213转动并使凹陷区216朝向套管212内的凸齿215位置时,套管212与插杆213能够相对滑动。Among them, convex teeth 215 are provided on the inner wall of the sleeve 212 and the outer wall of the insertion rod 213, and a recessed area 216 is also provided on the outer wall of the insertion rod 213. When the insertion rod 213 rotates and the convex teeth 215 on it engage with the convex teeth 215 in the sleeve 212, the position between the sleeve 212 and the insertion rod 213 is locked. At this time, the wrench 214 is tilted and overlapped on the worktable 205. When the insertion rod 213 rotates and the recessed area 216 is toward the position of the convex teeth 215 in the sleeve 212, the sleeve 212 and the insertion rod 213 can slide relative to each other.

详细的,两个直角座208之间通过套管212和插杆213连接,当通过扳手214转动插杆213,使插杆213上的凸齿215转动并卡入套管212内的凸齿215上时,套管212与插杆213之间处于卡接状态,此时套管212与插杆213无法相对运动,两个直角座208之间位置锁定,扳手214倾斜搭接在载物台205上,由此借助于扳手214自身重力,使插杆213无法随意转动,从而保持两个直角座208的锁定状态。In detail, the two right-angle seats 208 are connected by a sleeve 212 and an insertion rod 213. When the insertion rod 213 is rotated by the wrench 214, the convex teeth 215 on the insertion rod 213 are rotated and clamped into the convex teeth 215 in the sleeve 212, the sleeve 212 and the insertion rod 213 are in a clamping state. At this time, the sleeve 212 and the insertion rod 213 cannot move relative to each other, and the position of the two right-angle seats 208 is locked. The wrench 214 is tilted and overlapped on the worktable 205. With the help of the wrench 214's own gravity, the insertion rod 213 cannot rotate at will, thereby maintaining the locked state of the two right-angle seats 208.

当需要调节两个直角座208之间位置时,向上搬动扳手214使插杆213旋转,此时凹陷区216移动至套管212内的凸齿215区域,凹陷区216与套管212内的凸齿215处于分离状态,由此能够使插杆213在套管212内滑动,方便调节两个直角座208之间位置关系。When the position between the two right-angle seats 208 needs to be adjusted, the wrench 214 is moved upward to rotate the insertion rod 213. At this time, the recessed area 216 moves to the convex tooth 215 area in the sleeve 212. The recessed area 216 and the convex tooth 215 in the sleeve 212 are in a separated state, thereby allowing the insertion rod 213 to slide in the sleeve 212, thereby facilitating the adjustment of the position relationship between the two right-angle seats 208.

如图4和图8所示,相邻两个单板201之间通过板簧217连接;As shown in FIG. 4 and FIG. 8 , two adjacent single plates 201 are connected via a leaf spring 217 ;

每个所述单板201上均开设有通槽218,通槽218内侧壁上开设有卡槽;Each of the single plates 201 is provided with a through slot 218, and a card slot is provided on the inner wall of the through slot 218;

还包括滑块220,滑块220在多个单板201上的通槽218内滑动,滑块220上设置有与卡槽配合使用的卡棱,滑块220上倾斜设置有斜杆219,所述动力单元400为所述斜杆219提供推力。It also includes a slider 220, which slides in the through slots 218 on the multiple single plates 201. The slider 220 is provided with a clamping edge used in conjunction with the clamping slot. The slider 220 is obliquely provided with an inclined rod 219, and the power unit 400 provides thrust for the inclined rod 219.

详细的,每个单板201上均设置通槽218和卡槽,滑块220能够在多个通槽218之间滑动,从而使滑块220配置在不同单板201上,当需要推动单板201移动时,动力单元400对斜杆219提供作用力并推动斜杆219移动,斜杆219推动滑块220移动,滑块220上的卡棱朝向对应单板201上的卡槽方向移动并相互卡接,此时借助于动力单元400的推力,从而使单板201移动,该单板201带动剩余多个单板201移动,从而实现多个单板201的变形运动。In detail, each single board 201 is provided with a through groove 218 and a card slot, and the slider 220 can slide between multiple through grooves 218, so that the slider 220 is configured on different single boards 201. When the single board 201 needs to be pushed to move, the power unit 400 provides a force to the inclined rod 219 and pushes the inclined rod 219 to move, and the inclined rod 219 pushes the slider 220 to move. The card edges on the slider 220 move toward the card slot direction on the corresponding single board 201 and engage with each other. At this time, with the help of the thrust of the power unit 400, the single board 201 is moved, and the single board 201 drives the remaining multiple single boards 201 to move, thereby realizing the deformation movement of multiple single boards 201.

当滑块220需要作用在不同单板201上时,只需使滑块220上的卡棱与对应单板201上的卡槽分离,即可使滑块220在不同通槽218之间切换,从而调节电缆弯曲角度。When the slider 220 needs to act on different boards 201 , it is only necessary to separate the edge on the slider 220 from the slot on the corresponding board 201 , so that the slider 220 can be switched between different through slots 218 , thereby adjusting the bending angle of the cable.

板簧217可为相邻两个单板201之间提供弹性拉力,从而使多个单板201在自然状态时保持直线排列状,相邻两个单板201通过平面203相互贴合。The leaf spring 217 can provide elastic tension between two adjacent single boards 201 , so that the plurality of single boards 201 can be arranged in a straight line in a natural state, and the two adjacent single boards 201 can be attached to each other through the plane 203 .

当滑块220在不同单板201上时,滑块220朝向首个单板201方向的多个单板201为工作区,工作区内的单板201可对电缆进行弯曲,而滑块220朝向尾端的单板201方向的多个单板201为闲置区,闲置区内的多个单板201由于板簧217的作用不会发生弯曲变形。When the slider 220 is on different single boards 201, the multiple single boards 201 facing the first single board 201 of the slider 220 are the working area, and the single boards 201 in the working area can bend the cable, while the multiple single boards 201 facing the tail end of the single board 201 of the slider 220 are the idle area, and the multiple single boards 201 in the idle area will not bend or deform due to the action of the leaf spring 217.

如图3所示,还包括托板221和多个伸缩杆222,托板221的一端固定在底座100上,托板221的另一端固定在多个单板201中的首个单板201底部,伸缩杆222的活动端固定在剩余多个单板201中的一个单板201底部,伸缩杆222的固定端上设置有转盘223,转盘223转动安装在底座100上;As shown in FIG3 , it also includes a support plate 221 and a plurality of telescopic rods 222, one end of the support plate 221 is fixed on the base 100, the other end of the support plate 221 is fixed to the bottom of the first single board 201 among the plurality of single boards 201, the movable end of the telescopic rod 222 is fixed to the bottom of one single board 201 among the remaining plurality of single boards 201, and a rotating disk 223 is arranged on the fixed end of the telescopic rod 222, and the rotating disk 223 is rotatably mounted on the base 100;

其中,伸缩杆222穿过转盘223和底座100。The telescopic rod 222 passes through the rotating disk 223 and the base 100 .

详细的,多个单板201中的首个单板201利用托板221固定在底座100上,剩余每个单板201通过伸缩杆222和转盘223安装在底座100上,首个单板201位置固定,剩余多个单板201可利用伸缩杆222和转盘223移动,从而对多个单板201进行托举,当多个单板201变形时,伸缩杆222上的单板201可拉动伸缩杆222伸长,伸缩杆222同步倾斜,此时伸缩杆222带动转盘223在底座100上转动。In detail, the first single board 201 among the multiple single boards 201 is fixed on the base 100 by using a supporting plate 221, and each remaining single board 201 is installed on the base 100 by a telescopic rod 222 and a turntable 223. The position of the first single board 201 is fixed, and the remaining multiple single boards 201 can be moved by using the telescopic rod 222 and the turntable 223, so as to lift the multiple single boards 201. When the multiple single boards 201 are deformed, the single board 201 on the telescopic rod 222 can pull the telescopic rod 222 to extend, and the telescopic rod 222 tilts synchronously. At this time, the telescopic rod 222 drives the turntable 223 to rotate on the base 100.

如图3所示,所述调径单元300包括竖向滑动安装在底座100上的调节台301,调节台301与底座100之间通过气缸302连接,并且气缸302为调节台301提供移动动力,气缸302上横向滑动设有Z型板303,每个所述载物台205上均开设有与Z型板303配合使用的插槽;As shown in FIG3 , the diameter adjustment unit 300 includes an adjustment platform 301 vertically slidably mounted on the base 100, the adjustment platform 301 and the base 100 are connected via a cylinder 302, and the cylinder 302 provides a moving power for the adjustment platform 301, a Z-shaped plate 303 is horizontally slidably disposed on the cylinder 302, and each of the loading platforms 205 is provided with a slot for use with the Z-shaped plate 303;

所述调节台301上设置有第一电机304,第一电机304的输出端传动设有齿柱305,所述Z型板303上设置有与齿柱305配合使用的齿区。The adjusting platform 301 is provided with a first motor 304 , the output end of the first motor 304 is provided with a gear column 305 , and the Z-shaped plate 303 is provided with a gear area used in conjunction with the gear column 305 .

详细的,由于载物台205的调节工作需要使其能够竖直移动和水平移动,因此当Z型板303的端部插入多个载物台205上的插槽内时,可利用气缸302来推动Z型板303竖向移动,从而使载物台205竖直移动,利用第一电机304、齿柱305和Z型板303上的齿区来推动Z型板303横向移动,从而使载物台205横向移动。In detail, since the adjustment work of the worktable 205 requires that it can move vertically and horizontally, when the ends of the Z-plate 303 are inserted into the multiple slots on the worktable 205, the cylinder 302 can be used to push the Z-plate 303 to move vertically, thereby moving the worktable 205 vertically, and the first motor 304, the gear column 305 and the tooth area on the Z-plate 303 can be used to push the Z-plate 303 to move horizontally, thereby moving the worktable 205 horizontally.

当多个单板201变形时,移动状态的单板201可直接与Z型板303远离,即载物台205与Z型板303分离,从而不会对单板201的移动造成影响。When the plurality of single boards 201 are deformed, the single boards 201 in the moving state can be directly separated from the Z-shaped board 303 , that is, the stage 205 is separated from the Z-shaped board 303 , thereby not affecting the movement of the single boards 201 .

如图3所示,所述动力单元400包括开设在底座100上的长孔,长孔内滑动设有移动套401,移动套401上滑动穿插有推杆402,并且推杆402通过第二电机403和传动轮404提供动力,第二电机403固定在移动套401上,推杆402与斜杆219之间转动连接;As shown in FIG3 , the power unit 400 includes a long hole opened on the base 100, a moving sleeve 401 is slidably provided in the long hole, a push rod 402 is slidably inserted on the moving sleeve 401, and the push rod 402 is powered by a second motor 403 and a transmission wheel 404, the second motor 403 is fixed on the moving sleeve 401, and the push rod 402 is rotatably connected to the inclined rod 219;

底座100上设置有第三电机405,第三电机405的输出端传动设有蜗杆406,蜗杆406上螺装套设有螺套407,螺套407与移动套401连接,蜗杆406的长度方向与长孔的长度方向平行。A third motor 405 is provided on the base 100 , and a worm 406 is provided at the output end of the third motor 405 . A screw sleeve 407 is threadedly mounted on the worm 406 . The screw sleeve 407 is connected to the movable sleeve 401 . The length direction of the worm 406 is parallel to the length direction of the long hole.

详细的,第三电机405可通过蜗杆406和螺套407推动移动套401沿长孔方向移动,从而带动推杆402、斜杆219和滑块220移动,方便将滑块220移动至不同单板201上。In detail, the third motor 405 can push the movable sleeve 401 to move along the long hole direction through the worm 406 and the screw sleeve 407, thereby driving the push rod 402, the inclined rod 219 and the slider 220 to move, making it convenient to move the slider 220 to different single boards 201.

传动轮404与推杆402之间传动连接,第二电机403可通过传动轮404推动推杆402穿过移动套401并移动,此时推杆402通过斜杆219和滑块220推动单板201移动,从而使多个单板201变形。The transmission wheel 404 is connected to the push rod 402, and the second motor 403 can push the push rod 402 through the moving sleeve 401 and move through the transmission wheel 404. At this time, the push rod 402 pushes the single board 201 to move through the inclined rod 219 and the slider 220, thereby deforming multiple single boards 201.
