Description

Technical field:

[0002] The invention relates to a high-speed rubber core automatic line and a working method thereof. Background technology:

[0004] In the pencil production process, it is necessary to open a lower lead core groove for placing the lead core on the top surface of the lower lead core groove plate, and open an upper lead core groove for accommodating the lead core on the bottom surface of the upper lead core groove plate. The lead cores are placed one by one into the lower lead core groove on the top surface of the lower lead core groove plate by manual or roller, and then the upper lead core groove plate is superimposed on the lower lead core groove plate to form an integral pencil plate, thereby wrapping the lead core in the middle to form a sandwich structure, and finally the integral pencil plate is cut into pencils by cutting equipment. In order to realize the above working process, the traditional technology uses a combination of multiple devices, and the adjacent devices are manually transferred, which makes the overall production efficiency low.

[0005] In order to improve production efficiency, some manufacturers have disclosed pencil glue core equipment that combines multiple devices and reduces manual transportation. For example, Chinese patent publication No. CN213206225U discloses a glue core automatic line, which includes a frame and a feeding hopper on the frame for stacking pencil core plates. A groove planing mechanism for planing grooves on the surface of the plate and a pencil core plate gluing mechanism for gluing in the lead groove are sequentially arranged along the plate input to output direction. The rear end of the pencil core plate gluing mechanism has a pencil core plate conveying mechanism for transmitting the glued pencil core plate, and during the conveying process, the pencil core plate with the lead placed is stacked with another pencil core plate to form a sandwich structure through the lead core sorting and lead core feeding mechanisms. The above mechanism can conveniently realize the automatic forming and output of the pencil glue core, ensuring the quality and efficiency of the pencil glue core plate forming.

[0006] However, the above structural layout is not reasonable enough, and the distance between the gluing of the pencil lead board and the lead slot is relatively far. When the pencil lead board is transported over a long distance, not only the transmission track and the back of the pencil lead board are easily adhered to glue, but also foreign objects are easily dropped into the pencil lead slot, thereby affecting the quality of the formed pencil; at the same time, the connection between each mechanism is not smooth enough and the transport span is large, which makes the overall equipment stability poor, increases the requirements for the quality of the pencil board, not only the equipment cost and the use cost are high, but also the production is not stable enough and the defective rate is high.

[0018] Another technical solution adopted by the present invention is: a working method of a high-speed rubber core automatic line, comprising the following steps:

[0019] (1) stacking a plurality of lower lead core slot plates with the lead core placement slots facing upwards in a first U-shaped guide slot; stacking a plurality of lower lead core slot plates with the lead core placement slots facing downwards in a second U-shaped guide slot; and placing a plurality of lead cores in a lead core hopper;

[0020] (2) The first chain hook of the lower lead core slot plate conveyor line pushes the lower lead core slot plates in the first U-shaped guide groove to move along the direction of the first chain, and the lower lead core slot plates pass through the dust hood and the glue coating mechanism in turn. The dust hood removes dust from the lead core placement groove on the lower lead core slot plate, and the glue coating mechanism sprays glue on the lead core placement groove on the lower lead core slot plate; the second chain hook of the upper lead core slot plate conveyor line pushes the upper lead core slot plates in the second U-shaped guide groove to move along the direction of the second chain, and the glue coating assembly coats glue on the lead core placement groove on the upper lead core slot plate during the conveying process;

[0079] like Figures 1 to 5As shown, a high-speed glue core automatic line of the present invention comprises a glue core conveying mechanism 4, a lower lead core slot plate feeding and gluing mechanism 5, a lead core feeding mechanism 2 and an upper lead core slot plate feeding and gluing mechanism 3 which are sequentially arranged from right to left along the conveying direction of the glue core conveying mechanism 4, the glue core conveying mechanism 4 is provided with an adsorption component 6 located below the output end of the lower lead core slot plate feeding and gluing mechanism 5, the adsorption component 6 is used to receive and adsorb the lower lead core slot plates one by one downward onto the conveying plane of the glue core conveying mechanism 4; the lead core feeding mechanism 2 is arranged above the lead core placement area of ​​the glue core conveying mechanism 4, and a lead core screening conveying mechanism 1 is arranged above the lead core feeding mechanism 2; the glue core conveying mechanism 4 is provided with a pressing component 7 located above the output end of the upper lead core slot plate feeding and gluing mechanism 3, the pressing component 7 is used to press down the upper lead core slot plates one by one so that the upper lead core slot plates are glued with the lower lead core slot plates conveyed thereto. During operation, the lower lead core slot plate feeding and gluing mechanism applies glue to the lead core placement groove on the top surface of the lower lead core slot plate, and then transports it to the top of the adsorption component. The adsorption component receives and adsorbs the lower lead core slot plates one by one onto the conveying plane of the glue core conveying mechanism. Then the glue core conveying mechanism transports the lower lead core slot plate to the lead core placement area, and the lead core feeding mechanism places a lead core in each lead core placement groove on the top surface of the lower lead core slot plate to realize lead core loading; then the glue core conveying mechanism transports the lower lead core slot plate to the bottom of the pressing component, and the upper lead core slot plate feeding and gluing mechanism applies glue to the bottom surface of the upper lead core slot plate and the lead core placement groove on the bottom surface, and then the upper lead core slot plate is transported to the bottom of the pressing component, and the pressing component presses the upper lead core slot plates down one by one to glue the upper lead core slot plates and the lower lead core slot plates to form a glue core plate with a sandwich structure.

[0080] like Figure 6-16 As shown, in this embodiment, the lead core feeding mechanism 2 includes two synchronously rotatable feed turntables 201, and each feed turntable 201 is provided with a core feeding plate 202 on the side of which the fixed position can be rotated and adjusted relative to the feed turntable, and a lead core slot group 203 is provided on the periphery of the core feeding plate, and a protrusion 204 is provided on the periphery of the feed turntable 201, which can be moved from a non-lead core slot position of the core feeding plate 202 to a lead core slot position of the core feeding plate, and is used to block part of the lead core slots of the lead core slot group.

[0081] In the lead core feeding mechanism, multiple groups of lead core slot groups 203 can be provided, and adjacent groups of lead core slot groups 203 are arranged at intervals, and multiple groups of lead core slot groups 203 are evenly distributed on the core entry plate 202; the above-mentioned protrusions 204 can also be provided in multiple groups, and multiple protrusions are evenly distributed on the turntable, and each protrusion corresponds to a lead core slot group.

[0082] In the lead feeding mechanism, the lead slot group 203 includes a plurality of lead slots 2031 arranged at intervals.

[0083] In the lead core feeding mechanism, the upper surface of the protrusion 204 may be higher than or equal to the upper surface of the lead core groove.

[0084] In the lead core feeding mechanism, the top of the core entry plate 202 is the feeding end of the lead core, and the lead core screening and conveying mechanism 1 is located above the core entry plate 202. The lead core is vertically stacked in the vertical blanking trough 108 of the lead core screening and conveying mechanism 1. When the lead core trough of the core entry plate 202 rotates to the output end of the vertical blanking trough 108, the lead core goes from the vertical blanking trough 108 to the lead core trough of the core entry plate 202; the lower part of the above-mentioned core entry plate 202 is the discharge end of the lead core, and the lead core rotates to the lower part with the core entry plate 202 and the feeding turntable 201, and then the lead core in the lead core trough of the avoidance groove of the material discharging protection piece is just discharged. A lower lead core groove plate gluing mechanism 206 is provided on the side of the core entry plate to convey the lower lead core groove plate to the discharge position of the lead core, so that the lead core enters the different grooves on the upper surface of the lower lead core groove plate in sequence.

[0085] In the lead core feeding mechanism, the core feeding plate 202 is connected to the feeding turntable 201 via the feeding spindle 207, and the feeding spindle 207 is driven to rotate by the spindle driving device. Further, the spindle driving device may include a synchronous wheel 209 and a driving wheel 210 arranged at the end of the feeding spindle, and the synchronous wheel and the driving wheel are connected via a synchronous belt 211, and the driving wheel is driven by the motor to rotate and drive the synchronous wheel and the feeding spindle to rotate synchronously. It is worth noting here that the spindle driving device is not limited to this, and can also adopt various modes such as gear transmission or gear chain transmission, which are not limited here.

[0086] In the lead core feeding mechanism, the synchronous wheel is coaxially fixedly connected with the feed spindle through an expansion sleeve 212; the expansion sleeve is fastened by a fixing piece; the expansion sleeve is a prior art, and the expansion sleeve can be a hydraulic expansion sleeve. By unlocking the expansion sleeve, the synchronous wheel and the feed spindle can be quickly separated, and the expansion sleeve can be re-locked, so that the synchronous wheel and the feed spindle can be quickly reconnected. For example, when it is necessary to adjust the position of the lead core groove on the core feeding plate, it is only necessary to unlock the expansion sleeve to disconnect the connection between the synchronous wheel and the feed spindle, so as to facilitate the rotation of the core feeding plate, thereby adjusting the position of the lead core groove of the core feeding plate to match the conveying mechanism of the lead core plate. Furthermore, a protective cover 224 is provided on the outside of the synchronous wheel.

[0087] In the lead core feeding mechanism, the core feeding plate 202 is connected to the feeding turntable 201 by a positioning piece 213, the core feeding plate 202 is provided with an adjustment slot 214, the feeding turntable 201 is provided with a connection hole 215 corresponding to the adjustment slot 214, and the positioning piece passes through the adjustment slot and the connection hole to connect the core feeding plate and the feeding turntable; by adjusting the position of the core feeding plate and the turntable, it is possible to produce plastic core boards with the same center distance and different widths without replacing accessories. Furthermore, the positioning piece can be a screw, a bolt or any other connecting piece.

[0088] In the lead core feeding mechanism, the core entry plate 202 is formed by splicing two half core plates 2021; by setting the design of splicing two half core plates into the core entry plate, the core entry plate can be taken out by only unlocking the positioning piece, which is more convenient for maintenance. At the same time, the two half core plates have the same structure, which can help reduce production costs.

[0089] The feed turntable system can produce rubber core boards with the same center distance but different widths without changing accessories. When producing boards of different specifications, only four feed core boards of the same model need to be replaced, which greatly saves machine adjustment time, improves the versatility of the equipment, and reduces the cost of use.

[0090] In the lead core feeding mechanism, an arc groove 2022 is provided on the core entry plate 202, and an arc limit block 2011 is provided on the side of the feed turntable 201 to cooperate with the arc groove; when the rotation position of the feed turntable is adjusted, the arc limit block moves in the arc groove to limit the rotation angle of the feed turntable relative to the core entry plate.

[0091] In the lead core feeding mechanism, a pneumatic material blocking mechanism 216 is provided between the upper parts of the two feeding turntables to limit the lead cores in the lead core screening and conveying mechanism 1 from falling into the lead core slot group. Further, the pneumatic material blocking mechanism includes a control push plate 2161 and a push plate driving device 2162 for driving the control push plate to extend and retract. It is worth noting that the push plate driving device can be a cylinder, a hydraulic cylinder or other driving elements.

[0092] In the lead core feeding mechanism, a material guard 217 is provided in front of the core entry plate 202, and a baffle 225 is provided beside the material guard 217. The end of the material guard close to the feeding turntable 201 is provided with an avoidance slot 218 that matches the shape of the core entry plate 202. A limiting space 219 for limiting the lead core is formed between the lead core slot group 203 rotated to the avoidance slot and the end surface of the avoidance slot. Further, there is a certain gap between the core entry plate and the avoidance slot to avoid interference when the core entry plate rotates. At the same time, the distance of the gap is smaller than the diameter of the lead core to prevent the lead core from falling out, so that the lead core can be limited in the lead core slot when the core entry plate rotates, so that the lead core is rotated and transported from the upper part of the core entry plate to the lower part of the core entry plate, and is placed in the slot of the lead core plate in sequence.

[0093] The lead core feeding mechanism also includes a lead core feeding frame 220, and the core feeding plate 202 and the feeding turntable 201 are installed inside the lead core feeding frame 220. In order to ensure the stability of the rotation of the feeding turntable, the feeding spindle and the lead core feeding frame are connected through a bearing 208.

[0094] In this embodiment, when the lead core feeding mechanism is working: (1) the lead cores fall one by one into the lead core groove 2031 at the top of the core feeding plate 202. As the core feeding plate 202 and the feeding turntable 201 rotate synchronously, the lead cores are rotated from the top of the core feeding plate through the avoidance groove 218 of the material protection member to the lower part of the core feeding plate 202. The lead cores moved to the lower part of the core feeding plate 202 are separated from the limit of the avoidance groove 218 and then enter the grooves of the lower lead core groove plate in sequence; (2) when it is necessary to produce and match different quantities of lead cores, by unlocking the positioning member, The core feeding plate is rotated so that a certain number of lead core slots 2031 are rotated to overlap with the protrusions of the feeding turntable 201, and the protrusions 204 close the lead core slots, thereby adjusting the number of remaining lead core slots. After the adjustment is completed, the positioning member is re-locked; (3) When it is necessary to control the lead core to stop feeding, the push plate driving device of the pneumatic blocking mechanism drives the control push plate to extend, blocking the lead core slots and the feeding channel, so that the lead core stops being input into the core feeding plate; when it is necessary to continue feeding, the push plate driving device is reset to drive the control push plate to reset.

[0095] In another embodiment, a sensor 221 is provided behind the core feeding plate; the sensor is installed below the top of the lead core feeding frame through a sensor mounting plate 222. When the raised position of the feeding turntable just moves to the output end of the blanking channel, the sensor feedbacks a signal to control the control push plate of the pneumatic material blocking mechanism to push out, close the output port of the blanking channel, and prevent the lead core on the blanking channel from continuing to be fed; at the same time, an encoder 223 is provided at the output end of the lower lead core slot plate feeding and gluing mechanism, and the encoder, the sensor and the controller are electrically connected. During the conveying process, the encoder is used to detect whether the lower lead core slot plate gluing mechanism has a lower lead core slot plate output, so as to control the core feeding plate to feed the lead core, thereby preventing the waste of lead core. Specifically: when the encoder detects that there is no lower lead core slot plate output by the lower lead core slot plate gluing mechanism, the control push plate of the pneumatic material blocking mechanism extends, so that the lead core on the blanking channel can no longer enter the lead core slot of the feeding turntable, so that the number of lead cores already on the turntable just matches the lower lead core slot plate that has been output by the lower lead core slot plate gluing mechanism, to avoid the lead core continuing to be unloaded when there is no lower lead core slot plate delivered, and falling to the conveying surface of the lower lead core slot plate feeding and gluing mechanism, causing waste.

[0096] The advantages of this lead core feeding mechanism are:

[0097] (1) When it is necessary to produce and match different numbers of lead cores, the core feeding plate is rotated by unlocking the positioning parts so that a certain number of lead core slots are rotated to coincide with the protrusions of the feed turntable. The protrusions close these lead core slots, thereby adjusting the number of remaining lead core slots. After the adjustment is completed, the positioning parts can be re-locked. It is flexible to adjust and easy to use; (2) Bearings are installed on both sides of the feed spindle to ensure the stability of the turntable during movement. The transmission structure of hydraulic expansion sleeve plus synchronous belt is adopted, which is not only simple in structure and low in cost, but also easy and convenient to install and maintain; (3) The feed turntable system can produce rubber core boards with the same center distance and different widths without replacing accessories. When producing boards of different specifications, only four core feeding plates of the same model need to be replaced. Since the core feeding plates are assembled The lead core blanking control mechanism is easy to disassemble, greatly saving the time of adjusting the machine, improving the versatility of the equipment, and reducing the cost of use; (4) a lead core blanking control mechanism is added, which controls the blanking of the lead core by feedback from the encoder of the lower lead core slot plate feeding and gluing mechanism during the conveying process to determine whether there is any output from the lower lead core slot plate. When there is no output from the lower lead core slot plate, it is necessary to control the lead core to stop blanking. Specifically, when the raised position of the feed turntable just moves to the output end of the blanking slot, the raised position prevents the lead core in the blanking channel from continuing to be blanked. At the same time, the sensor feedbacks a signal, and the push plate drive device of the pneumatic material blocking mechanism drives the control push plate to extend, blocking the lead core slot and the blanking channel, so that the lead core stops being input to the core feed plate; when it is necessary to continue blanking, the push plate drive device resets and drives the control push plate to reset.

[0098] like Figure 17-23 As shown, in this embodiment, the rubber core conveying mechanism 4 includes a rubber core conveying line 401, and the rubber core conveying line 401 is provided with a lower lead core slot plate feeding station 8, a lead core feeding station 9 and an upper lead core slot plate feeding station 10 in sequence from right to left along the conveying direction. The output end of the lower lead core slot plate feeding and gluing mechanism 5 is located above the side of the lower lead core slot plate feeding station 8, and the adsorption component 6 is arranged at the lower lead core slot plate feeding station 8; the lead core feeding station 9 corresponds to the position of the lead core placement area, and the lead core feeding mechanism 2 is arranged at the lead core feeding station 9; the output end of the upper lead core slot plate feeding and gluing mechanism 3 is located above the upper lead core slot plate feeding station 10, and the pressing component is arranged at the upper lead core slot plate feeding station.

[0099] In the rubber core conveying mechanism, a lead core pressing roller 410 is provided above the rubber core conveying line 401 between the lead core feeding station 9 and the upper lead core slot plate feeding station 10 .

[0100] In the rubber core conveying mechanism, the adsorption assembly 6 includes a lifting adsorption plate 403 arranged at the lower pencil core slot plate feeding station 8 and used to adsorb the bottom surface of the lower pencil core slot plate. The lifting adsorption plate 403 is driven to lift by an electric mechanism. The top surface of the lifting adsorption plate is provided with a first adsorption hole 406, and the adsorption hole is externally connected to a vacuum pumping device. Further, a concave cavity for accommodating the lifting adsorption plate is provided on the horizontal work surface of the rubber core conveying line at the lower pencil core plate feeding station.

[0101] In the rubber core conveying mechanism, the upper lead core slot plate feeding station 10 is provided with a vacuum adsorption plate 416 for adsorbing the top surface of the upper lead core slot plate. The adsorption surface of the vacuum adsorption plate 416 is located at the bottom surface, and has a plurality of second adsorption holes 423 externally connected to the vacuum pumping device.

[0102] In the rubber core conveying mechanism, a downward pressing through hole is provided on the vacuum adsorption plate; the downward pressing component 7 includes a lifting and pressing plate 411 for passing through the downward pressing through hole and pressing the upper lead core slot plate, and the lifting and pressing plate 411 is driven to rise and fall by an electric mechanism.

[0103] In the rubber core conveying mechanism, a rubber core plate pressing roller 412 is arranged above the rubber core conveying line 401 at the next station of the upper lead core slot plate feeding station 10 .

[0104] In the rubber core conveying mechanism, transmission gaps 407 are provided on both sides of the conveying direction on the conveying plane 404 of the rubber core conveying line 401, and a circulating conveying chain 422 is provided inside and below the transmission gap 407. A plurality of conveying chain hooks 408 are fixedly provided at equal intervals in the length direction of the conveying chain 422, and the conveying chain hooks 408 are exposed from the corresponding transmission gaps 407. The conveying chain hooks 408 are used to push the lower lead core slot plate along the conveying direction.

[0105] In the rubber core conveying mechanism, in order to ensure the smooth operation of the conveying chain, guide rail grooves are set on the horizontal sections of the conveying chain 422 on the rubber core conveying line 401. The horizontal sections of the conveying chain are guided in the guide rail grooves, but the conveying chain hooks are located outside the guide rail grooves.

[0106] In the rubber core conveying mechanism, the conveying plane 404 of the rubber core conveying line 401 is provided with a vacuum adsorption section 409 for adsorbing the lower lead core slot plate on the lead core placement area, and the vacuum adsorption section 409 includes a plurality of third adsorption holes 424 distributed along the conveying direction, and the third adsorption holes are externally connected to the vacuum pumping device. The vacuum adsorption section performs appropriate vacuum adsorption on the lower lead core slot plate, so that the lower lead core slot plate can move smoothly under the push of the conveying chain hook, and the lower lead core slot plate can fit tightly on the conveying path, ensuring that the lead core always falls into the lead core placement groove on the top surface of the upper lead core slot plate when the lead core is dropped.

[0107] The working principle of the rubber core conveying mechanism is:

[0108] When the lower lead core slot plate is ready to fall from the output end of the upper lower lead core slot plate feeding and gluing mechanism 5 to the lower lower lead core slot plate feeding station 8, the lifting and adsorption plate 403 first rises and receives and adsorbs the lower lead core slot plate, and then the lifting and adsorption plate 403 descends to stably place the lower lead core slot plate on the lower lead core slot plate feeding station 8, and the posture of the lower lead core slot plate is relatively stable and not easy to tilt;

[0109] Subsequently, the lower lead core slot plate is gradually moved to the vacuum adsorption section 409 of the lead core placement area under the push of the conveying chain hook 408 on the upper section of the conveying chain 422. The vacuum adsorption section 409 performs appropriate vacuum adsorption on the lower lead core slot plate, so that the lower lead core slot plate can move smoothly under the push of the conveying chain hook. At this time, the process of placing the lead cores one by one into the corresponding lead core placement slot can be carried out on the vacuum adsorption section. At the same time, as the lower lead core slot plate is conveyed, the lead core pressing roller 410 rolls onto the lead core of the lower lead core slot plate. , press or compact the lead placed in the lead placement slot into the lead placement slot, so that the lead is not easy to run out of the lead placement slot during the subsequent transportation process; when the lower lead slot plate is transported to the bottom of the upper lead slot plate feeding station 10, the lifting and pressing plate 411 is used to press down the upper lead slot plate adsorbed on the bottom of the vacuum adsorption plate 416, so that it can be glued with the lower lead slot plate with the lead placed directly below to form a "sandwich"-like glue core plate, and the glue between the upper and lower lead slot plates is firm and stable. Finally, the glue core plate wrapped with the lead moves to the glue core plate pressing roller, and the glue core plate pressing roller further rolls the glue core plate to make the upper and lower pencil core plates more firmly glued.

[0110] In this embodiment, the lead core feeding mechanism and the rubber core conveying mechanism are driven by the same power source, specifically: the feed turntable of the lead core feeding mechanism and the conveying chain on the rubber core conveying line are connected via a chain or synchronous belt transmission to achieve synchronous transmission from the same power source. When the rubber core conveying line conveys the lower lead core slot plate to place the lead core and subsequently forms the rubber core board, it also drives the feed turntable to rotate synchronously to place the lead core, and the conveying direction of the lower pencil core board can be consistent with the rotation direction of the feed turntable, so the structure is stable and the structural cost is greatly optimized.

[0111] The advantages of the rubber core conveying mechanism are:

[0112] 1. When the lead cores are placed one by one into the corresponding lead core placement grooves, as the lower lead core groove plate is transported, the lead core pressing roller rolls onto the lead core of the lower lead core groove plate, pressing or compacting the lead core placed in the lead core placement groove into the lead core groove, so that the lead core is not easy to run out of the lead core groove during the subsequent transportation process;

[0113] 2. The pressing assembly is used to press down the upper lead core slot plate on the upper lead core slot plate feeding station, so that it can be glued with the lower lead core slot plate with the lead core placed directly below to form a "sandwich"-like glue core plate, and the upper and lower pencil core plates are firmly and stably glued.

[0114] like Figure 24-30 As shown, in this embodiment, the lower lead core trough plate material loading and gluing mechanism includes a body 501, a lower lead core trough plate conveyor line arranged on the body 501, and a first U-shaped guide groove vertically arranged above the lower lead core trough plate conveyor line. The conveying direction of the lower lead core trough plate conveyor line is perpendicular to the conveying direction of the glue core conveying mechanism. The lower lead core trough plate conveyor line includes a first chain that rotates in a circular manner. Both sides of the first chain 502 are respectively wound around a rotating drum, one of which is driven by a power input mechanism such as a motor. A plurality of first chain hooks 503 are fixedly provided at equal intervals in the length direction of the first chain. The spacing between two adjacent first chain hooks 503 is greater than the length of the lower lead core trough plate 506. The spacing between two adjacent first chain hooks 503 can be adjusted according to different sizes. The first U-shaped guide groove is used to guide and limit multiple stacked lower lead core groove plates, the first chain hook pushes the lower lead core groove plates in the first U-shaped guide groove to move along the travel direction of the first chain, and a dust suction cover and a glue coating mechanism are sequentially provided on the travel track of the lower lead core groove plate, and the glue coating mechanism sprays glue or sprays glue on the lead core placement groove on the lower lead core groove plate.

[0115] In the lower lead core groove plate feeding and gluing mechanism, the first chain hook 503 is T-shaped, and the lower part of the T-shaped first chain hook is fixed on the chain link of the first chain 502. The upper part of the first chain hook is designed to be T-shaped, so that the contact area when it pushes the lower lead core groove plate 506 can be increased, thereby avoiding the cracking of the lower lead core groove plate caused by excessive pressure of the first chain hook (when the first chain hook is a straight rod, its contact area with the lower lead core groove plate is small, and it is easy to squeeze on the strip groove and cause it to crack).

[0116] In the lower lead core slot plate loading and gluing mechanism, a support bottom plate 504 located above the first chain and a first U-shaped guide groove 505 located on the support bottom plate and vertically arranged are provided on the body 501. The first U-shaped guide groove 505 can be formed by stamping a metal plate. The first U-shaped guide groove 505 is used to guide and limit multiple stacked lower lead core slot plates 506 (the multiple stacked lower lead core slot plates are not shown in the figure). The lower lead core slot plates have multiple lead placement grooves 528 for placing pencil leads. Each lower lead core slot plate has a side with a lead placement groove facing upward. A groove 507 is provided on the support bottom plate to facilitate the extension of the first chain hook 503. The first chain hook pushes the lower lead core slot plates in the first U-shaped guide groove to move along the travel direction of the first chain.

[0117] In the lower lead core slot plate feeding and gluing mechanism, the slot 507 is arranged along the length direction of the first chain, the slot is in the shape of a strip, the slot width is greater than the width of the lower part of the T-shaped first chain hook, and a through slot 510 is arranged on the supporting bottom plate 504 and at the end of the slot, the through slot 510 is used for the upper part of the T-shaped first chain hook to pass through, and the shape of the through slot 510 is rectangular, such as Fig.28 As shown, during operation, the T-shaped first chain hook 503 enters the groove from the right through groove, and then moves from right to left with the first chain, and finally leaves the groove from the left through groove. This process can move the lowest lower lead core groove plate located on the supporting bottom plate and in the first U-shaped guide groove from right to left. According to the above continuous action, each lower lead core groove plate in the first U-shaped guide groove can be output for dust suction and glue spraying.

[0118] In the lower lead core groove plate material coating mechanism, in order to better position, a guide limit plate 511 is vertically provided on the support bottom plate 504 and opposite to the groove position of the first U-shaped guide groove. The lower lead core groove plate is limited by the first U-shaped guide groove and the guide limit plate to achieve front, back, left and right direction limitation. In order to release the materials separately, the upper part of the first U-shaped guide groove and the guide limit plate are bent outward by 10-20 degrees.

[0119] In the lower lead slot plate feeding and gluing mechanism, the dust hood 508 is a rectangular hood, the upper surface of the dust hood has a transparent window 527 for observing the dust collection situation, the dust hood has a round tube 512 connected to the negative pressure adsorption tube, two groups of brushes are arranged in the dust hood, the two groups of brushes are respectively mounted on the brush mounting plate 513, the brush mounting plate 513 is connected to the brush mounting seat 515 by the first bolt 514 (the two brushes and the brush mounting plate are opposite and spaced), the brush mounting seat has a vertical groove 516, the first bolt 514 is penetrated and connected in the vertical groove 516, and the end is connected to the brush mounting plate 513, and the height of the brush is adjusted by adjusting the height of the first bolt 514 in the vertical groove 516 to achieve the adjustment of the height of the brush; before gluing, two dust removal methods of brush and vacuum suction are added, which can effectively remove foreign matter on the pencil plate and greatly improve the yield rate.

[0120] In the glue coating mechanism for the lower lead core groove plate, the specific glue coating mechanism 509 includes, from bottom to top, a glue coating plate 517, a glue coating dispersion plate 518, and a glue coating cover 519 arranged above the glue coating dispersion plate. The lower cover opening of the glue coating cover 519 is sealed and connected to the periphery of the glue coating dispersion plate 518. The glue coating cover is provided with a glue input channel 520. A glue storage cavity is formed between the glue coating cover and the glue coating dispersion plate. A glue feeding hole 520 is provided on the glue coating plate 517. The gluing trough 521 has a row of glue spray holes 522 arranged at its bottom, the glue spray holes facing the strip grooves on the lower lead core groove plate where the lead core is installed, the glue dispersion plate 518 is provided with a plurality of glue holes 523, the glue holes connect the glue storage cavity and the gluing trough, the glue flows into the glue storage cavity from the glue input channel 520, passes through the glue holes 523 and enters the gluing trough 521, and is finally sprayed out from the glue spray holes 522.

[0121] In the gluing mechanism for the lower lead slot plate, in order to make separate adjustments, a gluing adjustment baffle 524 is installed on the body 501, and the gluing mechanism 509 is installed on the gluing adjustment baffle 524. A runway-shaped hole 525 is provided on the gluing adjustment baffle, and the runway-shaped hole 525 is arranged perpendicular to the travel direction of the lower lead slot plate 506. A second bolt 526 threadedly connected to the body is provided in the runway-shaped hole. The second bolt 526 is loosened during adjustment, and the second bolt 526 is tightened after the gluing adjustment baffle 524 is appropriately adjusted perpendicular to the travel direction of the lower lead slot plate 506. Through the above-mentioned adjustment mechanism, it can be suitable for the lower lead slot plates 506 of pencils of different specifications and models.

[0122] In the lower lead core slot plate feeding and gluing mechanism, a support plate 529 is rotatably hinged on the support base plate 504, and the support plate 529 is rotatably hinged on the seat body on the support base plate 504 through a pin shaft. The support plate has a horizontal position and a vertical position. In the horizontal position, the support plate is set to the side away from the groove to avoid the push rod from pushing the lower lead core slot plate. In the vertical position, the support plate is flipped to a vertical position to support the lower lead core slot plate located in the U-shaped guide groove; through the support plate 529, debugging and maintenance can be carried out without taking out the plate in the U-shaped guide groove, which is convenient for debugging the equipment.

[0123] The working principle of the lower lead core groove plate feeding and gluing mechanism is as follows: multiple pieces of lower lead core groove plates (the lower lead core groove plates have multiple lead core placement grooves for placing pencil leads, and the side with the lead core placement grooves faces upwards) are stacked and placed in a first U-shaped guide groove (completed manually or by a robot). As the first chain circulates, the first chain hook on the first chain pushes the lowest piece of lower lead core groove plate to move toward the dust hood and the gluing mechanism. When moving to the dust hood station, the negative pressure suction of the dust hood is used to absorb and discharge the debris generated when the lead core placement grooves of the lower lead core groove plate are made, and the lead core placement grooves on the lower lead core groove plate are sprayed with glue or coated with glue by the gluing mechanism.

[0124] The lower lead core slot plate feeding and gluing mechanism has a simple structure and a compact layout. The lower lead core slot plate is directly fed into the gluing mechanism after vacuum cleaning, thereby shortening the conveying distance and preventing foreign matter from adhering again during long-distance conveying, resulting in the lead core being unable to fit tightly to the lead core slot plate.

[0125] like Figure 31-34 As shown, in this embodiment, the lead core screening and conveying mechanism includes a lead core hopper 101 with a stacking port 102 at the bottom, two screening and conveying chains 103 for conveying lead cores and arranged in parallel are arranged below the lead core hopper 101, a screening gap is reserved between the two screening and conveying chains for the lead cores of unqualified length to fall, a discharging conveying wheel 104 located below the stacking port is arranged between the feeding ends of the two screening and conveying chains 103, and a discharging gap is reserved between the discharging side of the stacking port and the discharging conveying wheel for the lead cores to pass through; the lead cores in the lead core hopper roll into the stacking port It falls on the discharging conveyor wheel, and the friction between the lead core and the discharging conveyor wheel sends the lead core from the discharging gap to the screening conveyor chain. When the length of the lead core is less than the width of the screening spacing, at least one end of the lead core will not be on the screening conveyor chain, and it will fall from the screening spacing and be removed. Both ends of the lead core with qualified length will be on the screening conveyor chain and transported forward along the screening conveyor chain, thereby realizing automatic screening of lead cores with unqualified lengths, ensuring that the length of the lead core after screening meets the requirements and can be used for the next step of production, thereby improving the yield rate and reducing the loss of lead cores.

[0126] In the lead core screening and conveying mechanism, the discharge side of the stacking port is connected to a discharge adjustment baffle 105 for adjusting the size of the discharge gap; the height of the discharge adjustment baffle is adjusted according to the lead core specifications. When conveying lead cores of different specifications, there is no need to replace the discharge conveying wheel. Only the discharge adjustment baffle needs to be adjusted to an appropriate height. Lead cores of different specifications can be produced through the friction between the discharge conveying wheel and the lead core.

[0127] In the lead core screening and conveying mechanism, the discharge adjustment baffle is connected to the discharge side of the stacking port through an adjustment bolt, and the discharge side of the stacking port is provided with a vertical long hole adapted to the adjustment bolt.

[0128] In the lead core screening and conveying mechanism, the sprockets of the two screening conveyor chains are coaxially arranged to realize the synchronous movement of the two screening conveyor chains. The discharge conveyor wheel 104 is also coaxially arranged with the sprocket at the feed end of the screening conveyor chain to realize the synchronous movement of the discharge conveyor wheel 104 and the screening conveyor chain. The wheel axle of the sprocket at the feed end of the screening conveyor chain is coaxially connected to the main shaft of the motor.

[0129] In the lead core screening and conveying mechanism, a lead core dropping mechanism 106 is provided at the discharge end of the screening and conveying chain, and two sensors A107 for sensing the lead core are provided on the lead core dropping mechanism, one above and one below. The qualified lead cores after screening fall into the lead core dropping mechanism 106, and the stacked lead cores are sensed by the two sensors A107, and the start and stop of the discharge conveying wheel and the feeding speed are controlled according to the feedback of the lead core stacking height. Further, the lead core dropping mechanism includes two parallel vertical dropping troughs 108 for stacking the lead cores, and the two vertical dropping troughs are respectively located below the discharge ends of the two screening and conveying chains, and a wedge-shaped inlet 109 is provided at the upper end of the vertical dropping trough, and the width of the vertical dropping trough 108 is slightly larger than the lead core diameter, so that the lead core can be vertically stacked in the vertical dropping trough 108, and the use of direct drop feeding ensures that the lead cores in the hopper can be used for the next production, thereby reducing the loss of the lead core.

[0130] In the lead core screening and conveying mechanism, a lead core recovery box 110 for receiving lead cores with unqualified length is provided below the screening and conveying chain. When the length of the lead core on the screening and conveying chain is shorter than the required size, the lead core is removed and falls into the lead core recovery box.

[0131] In the lead core screening and conveying mechanism, a plurality of material-selecting grooves 111 are distributed at intervals around the discharging conveying wheel.

[0132] In the lead core screening and conveying mechanism, the inner bottom surface of the lead core hopper is a sloped surface, the stacking port is located at the lower part of the sloped surface, and a sensor B112 for sensing the lead core is provided in the lead core hopper; the lead core is placed in the lead core hopper, and the sloped surface at the bottom of the lead core hopper allows the lead core to fall smoothly into the stacking port, and the sensor B112 in the lead core hopper is used to sense the amount of lead core. When there is less lead core in the hopper, the height of the lead core is lower than the sensor B112, and the sensor B112 will send an alarm through the system to prompt the system to replenish the lead core.

[0133] The advantages of the lead core screening and conveying mechanism are: simple structure, reasonable design, good screening effect, convenient debugging, ability to remove lead cores with unqualified lengths, high working efficiency, ensuring that the length of the lead cores after screening meets the requirements, improving the yield rate, and reducing the loss of the lead cores.

[0134] like Figure 35-42As shown, in this embodiment, the upper lead core slot plate feeding and gluing mechanism includes an upper lead core slot plate conveyor line, a feeding assembly 314, a stacking assembly 315, a gluing assembly 301 and a vacuum adsorption assembly 316 arranged in sequence along the conveying direction of the upper lead core slot plate conveyor line, the conveying direction of the upper lead core slot plate conveyor line is perpendicular to the conveying direction of the glue core conveying mechanism, the upper lead core slot plate conveyor line includes a feeding panel, and the gluing assembly includes a coating seat 303 fixedly arranged at the lower end of the feeding panel, and the top of the coating seat is concavely provided with a glue holding groove 327, and the side end of the glue holding groove is provided with a longitudinally penetrating coating The glue hole 328 of the seat, the glue holding groove is symmetrically arranged on both sides horizontally with brush installation grooves 305 for installing the brush 304, the feeding panel is correspondingly provided with a through hole 306 for the brush to protrude and apply glue, and a reflux hole 307 is vertically penetrated on the coating seat outside the brush installation groove. The reflux holes are also symmetrically arranged on both sides of the glue holding groove, which are closer to the feeding end and the discharging end of the glue coating component than the brush installation groove. The lower ends of the reflux holes are connected and covered by a coating sealing plate 308 on the bottom of the coating seat to form a reflux cavity, and a reflux pipe 309 connected to the reflux cavity is provided on the coating sealing plate.

[0135] In the upper lead core slot plate feeding and gluing mechanism, a reflux port 310 communicating with the reflux hole is provided on the feeding panel, and two brushes act on the feeding end and the discharging end of the gluing component respectively. The brush at the feeding end can remove foreign matter, dust, etc. on the upper lead core slot plate during the gluing process. At the same time, the overflowing glue can also flow back to the bottom through the reflux port and the reflux hole for recycling, and the height of the brush at the discharging end can be adjusted to set the glue coating thickness. That is, a multi-chamber glue supply structure is adopted to ensure that plates of poor quality can also be evenly glued, while taking into account the problem of glue overflow recovery, which not only improves product quality but also reduces material loss.

[0136] In the upper lead core slot plate feeding and gluing mechanism, the brush height can be adjusted to prevent glue from overflowing and has the function of cleaning the plate. The upper lead core slot plate is coated with glue through the gluing area, and the glue layer is adjusted to a suitable thickness by adjusting the adjusting bolt under the discharge brush. The gluing system also has a reflux structure, which can recover glue overflowed due to improper debugging and avoid glue waste.

[0137] In the upper lead core groove plate feeding and gluing mechanism, the bottom end of the brush is set in the brush installation groove through the brush adjustment seat 311, and the installation groove is vertically opened with brush adjustment holes 312 on both sides along its length direction, and is screwed from bottom to top through the coating sealing plate and the brush adjustment hole and fixed on the brush adjustment seat to adjust the brush vertically. A butterfly nut is fixed at the bottom of the screw, and the height of the brush adjustment seat and the brush is adjusted by rotating the butterfly. A total of four brush adjustment holes are set, and four corresponding screws 331 are also set.

[0138] In the upper lead core slot plate material coating mechanism, the bottom of the coating seat is recessed upward with a square groove 313 in a square shape to facilitate connecting the bottom of the reflux hole, and the upper end of the reflux pipe is connected to the square groove.

[0139] In the upper lead core slot plate loading and gluing mechanism, the feeding assembly 314, the stacking assembly 315, the gluing assembly 301 and the vacuum adsorption assembly 316 are all fixed on the feeding panel, and the feeding assembly includes a second chain 317 that circulates and rotates below the feeding panel. As for the driving and circulating rotation method of the second chain, it is a universal setting and will not be elaborated on here. A plurality of second chain hooks 318 are fixedly provided at equal intervals in the length direction of the second chain, and the second chain hooks are all T-shaped. The lower part of the vertical section of the T-shaped second chain hook is fixed on the second chain, and a groove 319 for the second chain hook to extend out is provided on the feeding panel.

[0140] In the upper lead core slot plate loading and gluing mechanism, the stacking assembly includes a second U-shaped guide groove 321 fixedly connected to the upper end of the feeding panel and extending vertically for stacking the upper lead core slot plates, and a second guide limiting plate 322 is vertically provided on the feeding panel and directly opposite to the groove opening of the second U-shaped guide groove. The upper lead core slot plate is limited by the second U-shaped guide groove and the second guide limiting plate to achieve horizontal and vertical limitation, and a transverse movement channel 323 for a single upper lead core slot plate to pass through is reserved between the bottom of the second U-shaped guide groove and the feeding panel.

[0141] In the upper lead core slot plate feeding and gluing mechanism, the second slot is arranged along the length direction of the second chain, the second slot is in the shape of a strip, the width of the second slot is greater than the width of the vertical section of the T-shaped second chain hook, a second through slot 320 is arranged on the feeding panel and at the end of the slot, the second through slot is used for the upper horizontal section of the T-shaped second chain hook to pass through, the second through slot is provided with two, which are respectively opened on the side of the stacking component to be docked and the side to be pushed to the gluing component, one side is for the second chain hook to extend to the feeding panel to push the material, and the other side is for the second chain hook to be recovered below the feeding panel after the pushing is completed; when working, the T-shaped second chain hook enters the second slot from the second through slot on one side, and then moves horizontally with the second chain, and finally leaves the second slot from the second through slot on the other side, this process can push the lowest upper lead core slot plate located on the feeding panel and in the second U-shaped guide groove laterally, according to the above-mentioned continuous action, each upper lead core slot plate in the second U-shaped guide groove can be output for gluing.

[0142] The upper part of the second chain hook is designed to be T-shaped, so that the contact area when it pushes the upper lead core slot plate can be increased, thereby avoiding the upper lead core slot plate from being cracked due to excessive pressure from the push rod (when the second chain hook is a straight rod, the contact area between it and the upper lead core slot plate is small, and it is easy to squeeze on the strip groove of the upper lead core slot plate to cause it to crack. A plurality of lead core placement grooves for placing lead cores are recessed at intervals along the width direction of the bottom of the upper lead core slot plate, and the lead core placement grooves all extend and penetrate along the length direction of the upper lead core slot plate).

[0143] In the upper lead core slot plate feeding and gluing mechanism, the vacuum adsorption assembly includes two guide plates 324 fixedly connected to the feeding end surface of the feeding panel, the upper end cover of the guide plate is fixed with a vacuum adsorption plate 416, the outer end of the vacuum adsorption plate 416 extends horizontally out of the feeding panel and a negative pressure adsorption chamber 326 is fixed on the upper surface of the end, the bottom of the negative pressure adsorption chamber is open and covered on the vacuum adsorption plate 416, and a plurality of third adsorption holes 424 are vertically opened on the vacuum adsorption plate 416 and communicated with the negative pressure adsorption chamber to facilitate the lower end surface of the vacuum adsorption plate to adsorb the glue-coated upper lead core slot plate, and the yield rate is greatly improved by cooperating with the pressing device of the conveying mechanism of the rear process through the vacuum adsorption assembly.

[0144] In the upper lead core slot plate feeding and gluing mechanism, the two guide plates 324 are connected to the feeding panel by bolts, and one of the guide plates is provided with a plurality of strip holes 330 at intervals, and the strip holes are extended longitudinally. The spacing between the two guide plates can be adjusted by the strip holes and the bolts, so as to guide and limit the upper lead core slot plate that is about to enter the gluing assembly. The two guide plates are fixed above the gluing assembly, and cooperate with the vacuum adsorption plate to form a limiting channel for a single group of upper lead core slot plates to pass through for gluing.

[0145] In the upper lead core slot plate feeding and gluing mechanism, the feeding assembly is covered inside via a feeding protection cover 329, and the top of the feeding protection cover is fixedly connected to the bottom of the feeding panel.

[0146] In the upper lead core groove plate feeding and gluing mechanism, a second support plate is hinged on the feeding panel beside the second guide limiting plate, and the second support plate has a horizontal position and an oblique position after flipping. In the horizontal position, the second support plate is turned to the side away from the second groove to avoid the second chain hook from pushing the upper lead core groove plate. In the oblique position, the support plate is flipped to an oblique direction to support the upper lead core groove plate located at the bottom of the second U-shaped guide groove 321. Through the second support plate 333, debugging and maintenance can be carried out without taking out the plate in the second U-shaped guide groove, which is convenient for debugging the equipment.

[0147] The working principle of the upper lead core slot plate feeding and gluing mechanism is as follows: first, multiple upper lead core slot plates (the lower part of the upper lead core slot plates has multiple lead core placement slots for placing pencil leads, and the side with the lead core placement slots faces downward) are stacked and placed in the second U-shaped guide groove (completed manually or by a robot). As the second chain circulates, the second chain hook on the second chain pushes the lowest upper lead core slot plate to move toward the gluing assembly. After moving to the gluing assembly, the brush located at the feed end can effectively remove foreign matter, dust, etc. on the upper lead core slot plate, and the glue is filled up by injecting glue into the upper glue hole. At the same time, the overflowing glue can also flow back to the bottom through the reflux port and the reflux hole for recycling, and the glue coating thickness can be set by adjusting the height of the brush at the discharge end, that is, a multi-chamber glue supply structure is adopted to ensure that plates of poor quality can also be evenly glued, while taking into account the problem of glue overflow recovery, which not only improves product quality but also reduces material loss.

[0148] The advantages of the upper lead core slot plate feeding and gluing mechanism are:

[0149] 1. The glue coating component is acted on the feed end and the discharge end of the glue coating component through two brushes respectively. The brush at the feed end can remove foreign matter, dust, etc. on the upper lead core groove plate during the glue brushing process. At the same time, the overflowing glue can also flow back to the bottom through the reflux port and the reflux hole for recycling, and the glue coating thickness can be set by adjusting the height of the brush at the discharge end. That is, a multi-chamber glue supply structure is adopted to ensure that the plates with poor quality can also be glued evenly, while taking into account the problem of glue overflow recovery, which not only improves the product quality but also reduces material loss.

[0150] 2. The use of a wider T-shaped second chain hook and a feeding assembly with a smaller conveying interval can improve efficiency while avoiding cracking of the upper lead core slot plate during the conveying process.

[0151] 3. The yield rate is greatly improved by combining vacuum adsorption components with downward pressure components.

[0152] In this embodiment, Figure 1-5 As shown, the machine 11 is also included, the glue core conveying mechanism 4, the lower lead core slot board loading and gluing mechanism 5, and the upper lead core slot board loading and gluing mechanism 3 are all arranged on the top of the machine 11, the lower lead core slot board loading and gluing mechanism 5 and the upper lead core slot board loading and gluing mechanism 3 are located on the same side of the glue core conveying mechanism 4, and the machine 11 is provided with a loading pedal 12 between the lower lead core slot board loading and gluing mechanism 5 and the upper lead core slot board loading and gluing mechanism 3. The loading pedal is provided to facilitate the loading of the upper lead core slot board, the lower lead core slot board and the lead core after manual stepping.

[0153] In this embodiment, the working method of the high-speed rubber core automatic line includes the following steps:

[0154] (1) stacking a plurality of lower lead core slot plates with the lead core placement slots facing upwards in a first U-shaped guide slot; stacking a plurality of lower lead core slot plates with the lead core placement slots facing downwards in a second U-shaped guide slot; and placing a plurality of lead cores in a lead core hopper;

[0155] (2) The first chain hook of the lower lead core slot plate conveyor line pushes the lower lead core slot plates in the first U-shaped guide groove to move along the direction of the first chain, and the lower lead core slot plates pass through the dust hood and the glue coating mechanism in turn. The dust hood removes dust from the lead core placement groove on the lower lead core slot plate, and the glue coating mechanism sprays glue on the lead core placement groove on the lower lead core slot plate; the second chain hook of the upper lead core slot plate conveyor line pushes the upper lead core slot plates in the second U-shaped guide groove to move along the direction of the second chain, and the glue coating assembly coats glue on the lead core placement groove on the upper lead core slot plate during the conveying process;

[0156] (3) After the glue is sprayed, the lower lead core trough plate is transported to the lower lead core trough plate feeding station by the lower lead core trough plate conveyor line. The lifting adsorption plate located at the lower lead core trough plate feeding station receives and adsorbs the bottom of the lower lead core trough plate, and drives the lower lead core trough plate to move downward to the conveying plane of the glue core conveyor line. Then, the conveying chain hook of the glue core conveyor line pushes the lower lead core trough plate to move toward the lead core feeding station; and the upper lead core trough plate after the glue is coated is transported to the upper lead core trough plate feeding station by the upper lead core trough plate conveyor line. The vacuum adsorption plate at the upper lead core trough plate feeding station adsorbs the upper lead core trough plate;

[0157] (4) When the lower lead core slot plate is transported to the lead core feeding station, the vacuum adsorption section at the lead core placement area performs vacuum adsorption on the bottom of the lower lead core slot plate; then, as the lower lead core slot plate is transported and the feed turntable rotates synchronously, the lead cores on the feed plate on the side of the feed turntable fall into the lead core placement slots of the lower lead core slot plate in sequence, and one lead core falls into each lead core placement slot, thereby realizing lead core feeding;

[0158] (5) As the lower lead core groove plate is conveyed, the lead core pressing roller rolls onto the lead core of the lower lead core groove plate, pressing or compacting the lead core placed in the lead core placement groove into the lead core placement groove;

[0159] (6) When the glue-coated upper lead core slot plate is conveyed by the upper lead core slot plate conveyor line to the lower part of the upper lead core slot plate feeding station, the lifting and pressing plate penetrates downward through the pressing hole to press down the upper lead core slot plate adsorbed on the bottom surface of the vacuum adsorption plate, so that the upper lead core slot plate can be glued with the lower lead core slot plate with the lead core placed thereunder, forming a sandwich structured glue core plate;

[0160] (7) The rubber core conveyor line conveys the rubber core board to the turntable stacking mechanism. The rubber core board changes from a horizontal state to a sideways state and is stacked on the storage platform.
