Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wood processing equipment, in particular to an automatic polishing production line for slender rod parts. BACKGROUND

[0002] Currently, slender round wood strips are often used as main materials for making handicrafts or wooden products. These round wood strips are generally made from the wood core left after the whole wood is planed. This not only utilizes waste but also reduces the consumption of wood. However, the surface of the wood core is relatively rough after being planed by a planer, which cannot meet the requirements of subsequent handicraft or wooden product processing. Therefore, the slender round rods usually need to be surface polished, such as using a polishing device to polish the surface of the slender round rod.

[0003] For polishing work of such slender round rod structure, a chopstick polishing machine is disclosed in patent No. CN218947241U. The chopstick polishing device adopts a flow line design and can realize automatic feeding, automatic polishing, and discharging, with high automation. The patent technology provides uniform speed driving sources by setting a polishing mechanism, two groups of servo motors and speed reducers, and then cooperates two groups of main synchronous wheels, polishing rollers, slave synchronous wheels, drive shafts, driven shafts, limit shafts, and polishing belts. The two groups of staggered polishing rollers and polishing belts realize alternating and efficient polishing of chopsticks, enhance the polishing effect of chopsticks, improve the polishing quality of chopsticks, and make the chopsticks polished successfully at one time without rework, saving time and effort. However, in this technical solution, multiple chopsticks may be fed at the same time when the hopper feeds, which leads to uneven polishing and polishing jamming of the polishing mechanism when polishing chopsticks. Moreover, in this technical solution, the chopsticks after being fed by the hopper are only conveyed into the polishing mechanism by the supporting seats on the transfer frame for polishing. However, the chopsticks are simply placed on the supporting seats without any fixing structure to fix or limit them. When the supporting seats move the chopsticks to the working area of the polishing mechanism, the rotating polishing rollers and polishing belts are likely to shake or pop up the chopsticks when they contact the chopsticks, and the popped-up chopsticks are likely to be inserted between the polishing belt and the polishing roller and jam them, affecting the subsequent processing.

[0037] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0038] Reference Figures 1 to 12The application provides an automatic polishing production line for elongated rod pieces, which comprises a piece-by-piece feeding device 100, a clamping and feeding device 200, a polishing device 300, a discharging and receiving device 400 and a control system 500. The piece-by-piece feeding device 100 can feed and deliver the elongated rod pieces one by one. The clamping and feeding device 200 comprises a rack 210, a receiving and conveying mechanism 220, a clamping mechanism 230 and a positioning device 240. The receiving and conveying mechanism 220 is rotatably installed on the rack 210 and used for receiving the elongated rod pieces delivered by the piece-by-piece feeding device 100. The working end of the clamping mechanism 230 can be swingably installed on the side of the rack 210 away from the output end of the piece-by-piece feeding device 100. The clamping mechanism 230 can swing open and close relative to the receiving and conveying mechanism 220 and cooperate with the receiving and conveying mechanism 220 to clamp and feed the elongated rod pieces outward. The positioning device 240 is arranged on the rack 210 above the output end of the receiving and conveying mechanism 220. The positioning device 240 can effectively position the elongated rod pieces clamped and fed by the receiving and conveying mechanism 220 and the clamping mechanism 230. The polishing device 300 is used for receiving and polishing the elongated rod pieces clamped and fed by the receiving and conveying mechanism 220 and the clamping mechanism 230. The discharging and receiving device 400 is used for receiving the elongated rod pieces delivered by the polishing device 300. The control system 500 is electrically connected with the piece-by-piece feeding device 100, the receiving and conveying mechanism 220, the clamping mechanism 230, the discharging and receiving device 400 and the polishing device 300.

[0039] The polishing device 300 can be a conventional polishing device. For example, the patent with publication number CN218947241U discloses a polishing mechanism in a chopstick polishing machine, which is not described in detail herein. The piece-by-piece feeding device 100 can adopt the structural design of the feeding bin and the first feeding assembly in the bamboo chopstick sharpening and polishing machine disclosed in the patent with publication number CN218557449U. It should be noted that the design can only be used for feeding short rod structures, and the selection should be made according to the requirements.

[0040] In addition, the control system 500 can adopt a conventional control cabinet system in the present application, and of course in some embodiments, the control system can also be adaptively improved on the basis of the conveying system and the conveying method thereof disclosed in the patent with publication number CN105584823A, which will not be described in detail herein. In an embodiment of the present application, the control system 500 includes a control cabinet, a programmable control board, a microprocessor, a memory, and an input / output interface, which are basic modules arranged in the control cabinet. The microprocessor, the memory, and the input / output interface are all installed on the programmable control board. The programmable control board is connected to the single-rod feeding device 100, the receiving conveying mechanism 220, the clamping mechanism 230, the discharging receiving device 400, and the polishing device 300 through the input / output interface. A control panel is arranged on the control cabinet and connected to the programmable control board. Workers can control the start-stop or action of the single-rod feeding device 100, the receiving conveying mechanism 220, the clamping mechanism 230, the discharging receiving device 400, and the polishing device 300 through the control panel. This technology is conventional and will not be described in detail herein.

[0041] The single-rod feeding device 100 is used to feed the slender rods one by one in the slender rod polishing production line, which ensures the quality of feeding and the polishing quality of the subsequent polishing device 300. The receiving conveying mechanism 220 is used to receive the slender rods output by the single-rod feeding device 100, and the clamping mechanism 230 is used to clamp and convey the slender rods, which ensures the reliability of conveying. In addition, the clamping device can be designed to swing, which provides space for the discharging of the slender rods. Furthermore, the positioning device 240 is used to position the slender rods clamped and conveyed by the receiving conveying mechanism 220 and the clamping mechanism 230, which ensures the accuracy and stability of the conveying direction of the slender rods output by the clamping device, and is beneficial to the polishing of the subsequent polishing device 300. The discharging receiving device 400 is used to receive the slender rods output by the polishing device 300, which avoids the swinging of the slender rods when they pass through the polishing device 300 due to the lack of fixing or limiting structure at the passing end, and ensures the polishing quality of the slender rods by the polishing device 300. The control system 500 is used to control the action of the single-rod feeding device 100, the receiving conveying mechanism 220, the clamping mechanism 230, the discharging receiving device 400, and the polishing device 300, which further improves the automation capability and work efficiency and reduces the labor intensity.

[0042] Referring to Figures 3 to 6In an embodiment of the present application, in order to adapt to the polishing processing requirements of the wood core formed after the veneer is planed, in an embodiment of the present application, the piece-by-piece feeding equipment 100 comprises a storage device 110 for storing and pushing out the stacked elongated rod members, at least one feeding device 120 for receiving the elongated rod members discharged by the storage device 110, and a poking device 130. The lifting mechanism 140 is provided on the feeding device 120, and a plurality of lifting structures 141 are provided on the lifting mechanism 140. The opening clamping groove 142 for accommodating the elongated rod member is provided on the lifting structure 141, and the width and depth of the opening clamping groove 142 are only adapted to one elongated rod member. The poking device 130 is installed on the feeding device 120, and the poking device 130 can remove the excess elongated rod members in the opening clamping groove 142. The control system 500 is electrically connected with the storage device 110, the feeding device 120, and the poking device 130.

[0043] It should be noted that, in order to remove the excess elongated rod members in the opening clamping groove 142, that is, when there are two or more elongated rod members in one opening clamping groove 142, even if the width and depth of the opening clamping groove 142 are limited to only adapt to one elongated rod member, generally, lifting one elongated rod member needs to lift both ends of the rod-shaped workpiece at the same time, so as to ensure the stability of the rod-shaped workpiece. Therefore, in actual use, two lifting structures 141 are generally provided at the same level, and the two lifting structures 141 are used to clamp both ends of the rod-shaped workpiece in the opening clamping groove 142, thereby realizing stable lifting of the rod-shaped workpiece. In the actual lifting process, since two lifting structures 141 are used to clamp both ends of the same rod-shaped workpiece, there are two lifting structures 141 each clamping one end of a rod-shaped workpiece, and at this time, the other end of the two rod-shaped workpieces is clamped in the opening clamping groove 142 due to the weight and is lifted together with the lifting structure 141. Therefore, in the present application, there is a case that two lifting structures 141 at the same level lift two rod-shaped workpieces at the same time, which easily leads to feeding errors and seriously affects the normal work of the later polishing equipment. The main purpose of the design of the poking device 130 in the present application is to solve the above problems and ensure that two lifting structures 141 at the same level lift one elongated rod member together, thereby realizing piece-by-piece feeding.

[0044] In an embodiment of the present application, in order to improve the stacking capacity and reduce the frequency of manual feeding, the storage device 110 comprises a support frame 111, support chains 112 rotatably arranged on both sides of the support frame 111, and a feeding motor 113 mounted on the support frame 111, the rotation centers of the two ends of the support chains 112 are connected by a main shaft 115, the output end of the feeding motor 113 drives the main shaft 115 to rotate through a belt, in turn driving the two support chains 112 to rotate synchronously; the support frame 111 is provided with a guide rod 114 inclined downward and connected to the feeding end of the feeding device 120 at the front end.

[0045] Referring to Figures 3 to 6 The feeding device 120 can adopt a conventional lifting device, for example, the patent with publication number CN114348593A discloses a toothpick round stick machine automatic feeding device, as long as it can lift the slender rod. In order to realize precise feeding one by one, the feeding device 120 in the present application is provided with two, two feeding devices 120 are connected in sequence, and a sliding rod 121 is inclinedly arranged between the two feeding devices 120, one end of the sliding rod 121 is connected to the discharge end of the feeding device 120 at the front end, the other end of the sliding rod 121 is connected to the feeding end of the feeding device 120 at the rear end, and a stirring device 130 is installed on the feeding device 120 at the rear end. Among them, the width or depth of the opening clamping groove 142 in the lifting structure 141 on the feeding device 120 at the front end is larger than that of the opening clamping groove 142 in the lifting structure 141 on the feeding device 120 at the rear end. The main purpose of this is to use the opening clamping groove 142 in the lifting structure 141 at the front end to disperse the slender rod pile supplied by the storage device 110, so that these dispersed slender rods fall into the two sliding rods 121, reducing the number of slender rods, and then ensuring that the lifting structure 141 on the feeding device 120 at the rear end can feed one by one. In addition, in the present application, in order to ensure stable feeding of the feeding device 120 at the rear end, the lifting structure 141 on the feeding device 120 at the front end can lift two slender rods at the same time, which can ensure that the feeding device 120 at the rear end always has slender rods for feeding. The stirring device 130 installed on the feeding device 120 at the rear end can ensure that the feeding device 120 at the rear end can realize feeding one by one.

[0046] But in the present application, due to the wood core after planing due to its own fiber and environmental influence, it is easy to cause the wood core to bend and overlap each other, in order to solve the above wood core feeding problem, therefore in an embodiment of the present application, the lifting mechanism 140 includes frame body 143, two rotating shafts 144 arranged on the frame body 143 and driving motor 145, two rotating shafts 144 are not in the same vertical plane, both ends of two rotating shafts 144 are provided with driving gear 146, driving gear 146 on the same side of two rotating shafts 144 is wound with lifting chain 147, two lifting chains 147 are provided with several lifting structures 141, opening clamping groove 142 is arranged on the outer side of lifting structure 141, and the opening clamping groove 142 on the two lifting chains 147 is one-to-one corresponding; the driving motor 145 is connected with one end of any rotating shaft 144 through the belt; the pre-ejecting mechanism and the lever mechanism are installed on the frame body 143. In this embodiment, the lifting structure 141 on the two lifting chains 147 is also one-to-one corresponding, which ensures that the opening clamping groove 142 on the one-to-one corresponding lifting structure 141 is in the same horizontal plane, and ensures that the elongated rod can be smoothly lifted when lifting the same elongated rod in the later stage, avoiding the situation that the elongated rod slips off.

[0047] In some embodiments, in order to make the elongated rod placed in the opening clamping groove 142 separate smoothly from the opening clamping groove 142, and ensure the stable conveying of the elongated rod, some receiving structures can be arranged on the top of the lifting mechanism 140, such as receiving plate. In an embodiment of the present application, the frame body 143 is provided with stripping fan 148 on the outer side of both ends of the rotating shaft at the top, the outer periphery of the stripping fan 148 is provided with feeding slope near one end of the feeding end of the lifting chain 147, and the outer periphery of the stripping fan 148 is provided with stripping section outwardly. Wherein, when the lifting chain 147 lifts the elongated rod to the top of the lifting mechanism 140, it will gradually enter the feeding slope, and with the gradual increase of the slope surface of the feeding slope and the continuous lifting of the lifting chain 147, the two ends of the elongated rod continue to slide forward on the two feeding slopes due to inertia until they slide to the stripping section, at this time the elongated rod continues to slide on the stripping section to the next equipment, such as the feeding port of the polishing equipment, or the inlet of the detection equipment. The stripping fan 148 is designed as an arc ring, and is eccentrically arranged and installed with the rotating shaft, so that the elongated rod on the lifting chain 147 can better enter the front end of the feeding slope.

[0048] Further referring to Figure 5 and Figure 6The poking device 130 includes pre-ejecting mechanisms and poking rod mechanisms, which are both installed on the feeding device 120 on both sides of the lifting mechanism 140; the working end of the pre-ejecting mechanism is projected on the side of the lifting mechanism 140 at a height higher than the height of the opening card slot 142 and lower than the height of the opening of the opening card slot 142; when the lifting mechanism 140 lifts the elongated rod member through the opening card slot 142, the two groups of pre-ejecting mechanisms can lift the elongated rod member accommodated in the opening card slot 142 to the opening of the opening card slot 142, and the elongated rod member is still clamped in the opening card slot 142; the poking rod mechanism is installed on the lifting mechanism 140 and located behind the pre-ejecting mechanism; when the lifting mechanism 140 lifts more than one elongated rod member through the same opening card slot 142, the poking rod mechanism can lift all the elongated rod members in the opening card slot 142. The main purpose of the pre-ejecting mechanism is to lift the elongated rod member in the opening card slot 142. If the two ends of the elongated rod member are clamped in two opening card slots 142 at the same horizontal level, the elongated rod member will not fall from the two opening card slots 142 when the pre-ejecting mechanism lifts the elongated rod member; if one end of each of the two opening card slots 142 clamps one elongated rod member, the elongated rod member will naturally fall back to the bottom of the lifting mechanism 140 and be lifted by the other group of lifting structures 141 due to the difficulty of being stably clamped by the corresponding opening card slot because of the weight of the elongated rod member.

[0049] Further, in order to make the elongated rod member smoothly pass through when contacting the pre-ejecting mechanism during lifting, in an embodiment of the present application, the pre-ejecting mechanism includes a mounting seat 131, an adjusting rod 132 mounted on the mounting seat 131, and a pushing wheel 133 rotatably mounted on the upper end of the adjusting rod 132, the mounting seat 131 is installed on the feeding device 120 and located on the outside of the lifting mechanism 140, and the mounting seat 131 is provided with an adjusting nut 134 for adjusting the extension amount of the adjusting rod 132. The adjusting nut 134 is rotatably mounted on the corresponding hole of the mounting seat 311, and the lower end of the adjusting rod 132 is screwed into the adjusting nut 134 and the hole. The extension amount of the adjusting rod 132 needs to satisfy that the height of the top end of the pushing wheel 133 can make the outer side of the single elongated rod member flush with the opening of the opening card slot 142, or the outer side of the single elongated rod member partially exceeds the opening card slot 142, as long as the single elongated rod member is still clamped in the opening card slot 142.

[0050] In the above embodiment, if only one end of the single elongated rod is clamped in one open clamping groove 142, it is difficult to ensure that the whole single elongated rod is pushed down by the pushing wheel 133 alone, and at this time, two open clamping grooves 142 on the same horizontal plane can each carry one elongated rod. Therefore, in order to further ensure that the elongated rods can be fed one by one, and also to ensure that the two ends of the elongated rod are clamped in the open clamping grooves 142 on the same horizontal plane, and to ensure the accurate feeding of the subsequent polishing equipment, the open clamping groove 142 located in the working area of the lever mechanism can be used to push down all the elongated rods clamped in the open clamping groove 142. In an embodiment of the present application, in order to improve the intelligent feeding, the lever mechanism includes a photoelectric sensor 135, a pushing piece 136, and a pushing block 137 arranged on the telescopic end of the pushing piece 136. The pushing piece 136 is installed on the feeding device 120 and located on the outer side of the lifting mechanism 140. The photoelectric sensor 135 is installed on the feeding device 120. When the photoelectric sensor 135 detects that the lifting mechanism 140 lifts multiple elongated rods through the open clamping groove 142, the pushing piece 136 can push all the elongated rods in the open clamping groove 142 outward through the pushing block 137. The control system 500 matched with the photoelectric sensor 135 can determine whether there are multiple elongated rods in the same open clamping groove 142 according to the interval time of the elongated rods detected by the photoelectric sensor 135 twice in succession, which greatly reduces the complexity of the control system 500. At the same time, in the present application, the distance between the two adjacent open clamping grooves 142 can also be set, and the running speed of the lifting mechanism 140 can also be set, so that the photoelectric sensor 135 can effectively detect whether there are multiple elongated rods in the same open clamping groove 142, and improve the accuracy of monitoring. It should be noted that in the above embodiment, the pushing piece 136 can be a telescopic pneumatic cylinder or a pushing electric cylinder structure, which is also electrically connected with the microprocessor of the control system 500.

[0051] Further, in the above embodiment, the identification of the number of elongated rod clamps is entirely relied on the photoelectric sensor 135, which increases the complexity of the control system 500. Of course, in an improved embodiment of the present application, in order to reduce the complexity of the entire control system 500, the lever mechanism in the present application can not use the intelligent identification method; see Figure 6The poking rod mechanism comprises an adjusting seat 138 and a poking rod 139 hinged at one end of the adjusting seat 138, the poking rod 139 is capable of automatic reset, the adjusting seat 138 is installed on the feeding device 120 and located on the outside of the lifting mechanism 140, when the lifting mechanism 140 lifts the elongated rod through the open clamping groove 142, the elongated rod can drive the poking rod 139 to swing. Wherein, the adjusting seat 138 is a structure capable of lifting, which is mainly used to adapt to open clamping grooves 142 of different depths and different specifications. In order to ensure the success rate in the application, when the lifting mechanism 140 lifts the elongated rod through the open clamping groove 142, if the two ends of the elongated rod are respectively clamped in two open clamping grooves 142 at the same horizontal, the two ends of the elongated rod will drive the two poking rods 139 on the two sides to swing synchronously, because the force is uniform, the elongated rod is limited on one side of the bottom of the open clamping groove. Therefore, the two ends of the elongated rod are longer than the distance between the two poking rods 322 on the two adjusting seats 321 in the actual process, so if the open clamping grooves 212 at the same horizontal clamp two elongated rods at the same time, the open clamping grooves 212 on one side must clamp one end of one elongated rod respectively, and the other end of the elongated rod is a movable end, at this time the poking rod 139 will collide with the end of the elongated rod, and the other end is not limited, therefore, the end of the elongated rod far away from the poking rod 139 will swing around the open clamping groove 142 to the side of the poking rod 139 at this time, so that the elongated rods clamped in the open clamping groove 142 will fall off, at this time some guide structures can be used to make the elongated rods that swing and fall off continue to fall back to the bottom of the lifting mechanism 140, waiting for the next time to be lifted.

[0052] Further referring to Figures 7 to 8After the above feeding device 120 finishes feeding the single elongated rod, the stripping section of the elongated rod on the stripping fan 148 falls in the output direction. At this time, in order to better achieve the functions of receiving the elongated rod and subsequent pinch feeding of the elongated rod, in an embodiment of the present application, the receiving and conveying mechanism 220 includes a conveying motor 221, at least two groups of drive shafts 222, and a plurality of bearing wheels 223 mounted on the drive shafts 222. The two groups of drive shafts 222 are rotatably mounted on the rack 210. The conveying motor 221 is mounted on the rack 210 and its output end is connected to any one of the drive shafts 222 through a belt, and the two groups of drive shafts 222 are connected through a synchronous belt. The bearing wheels 223 are provided with a plurality of corrugated grooves 224 in the circumferential direction. The rack 210 is provided with a support groove plate 225 with a trumpet-shaped cross section in the area between the two groups of drive shafts 222. The bottom of the support groove plate 225 is lower than the pinch feeding plane formed by the cooperation of the bearing wheels 223 and the pinch feeding mechanism 230. The control system 500 is electrically connected to the conveying motor 221. Among them, the two ends of the elongated rod are received by the bearing wheels 223 on the two groups of drive shafts 222, which can effectively avoid more areas contacting the elongated rod, and at the same time there is enough space to accommodate the area where the elongated rod deforms. It should be noted that the two groups of drive shafts 222 are respectively located on the two sides of the lifting mechanism 140 and the outward ends thereof are directed to the output end of the lifting mechanism 140. In addition, the drive shafts 222 can also be provided as four groups, wherein two groups are provided on each side of the lifting mechanism 140, so that elongated rods of different length specifications can be set.

[0053] Among them, the corrugated grooves 224 are mainly used to avoid the sliding of the elongated rod on the bearing wheels 223 due to the deformation of the elongated rod itself during the clamping of the elongated rod, and the corrugated grooves 224 are used to limit the deformation swing of the elongated rod when it is pressed by the pinch feeding mechanism 230. The main function of the support groove plate 225 is to receive the elongated rod that is too curved and to limit the falling position of the elongated rod. The bottom of the support groove plate 225 is lower than the pinch feeding plane formed by the cooperation of all the bearing wheels 223 and the pinch feeding mechanism 230, which can accommodate some elongated rods that are curved and deformed in the middle, and also reduces the influence of the bearing wheels 223 on conveying the elongated rod.

[0054] In some embodiments, in order to facilitate the above-mentioned function of opening and closing relative to the carrying conveying mechanism 220, the clamping mechanism 230 comprises a telescopic part 231 hinged at one end to the rack 210, a swing shaft 232 rotatably mounted on the rack 210, at least two sets of swing arms 234 respectively arranged on both ends of the swing shaft 232, and clamping wheels 235 rotatably mounted on the swing arms 234. The swing shaft 232 is provided with a driving arm 236, the other end of the telescopic part 231 is hinged to the driving arm 236, and the outer periphery of the clamping wheel 235 is provided with a V-shaped groove 233 capable of positioning the elongated rod part in cooperation with the carrying conveying mechanism 220. The control system 500 is electrically connected to the telescopic part 231. Among them, the telescopic part 231 is a conventional telescopic electric cylinder or air cylinder, and the telescopic movement of the telescopic part 231 can drive the swing shaft 232 to rotate, thereby driving the clamping wheels 235 on the swing arms 234 to move close to or away from the carrying conveying mechanism 220, realizing the relative opening and closing of the clamping wheels 235 and the carrying conveying mechanism 220 in order to receive the elongated rod part output by the receiving and lifting mechanism 140 or clamp the elongated rod part. In the above-mentioned embodiment, the main purpose of the V-shaped groove 233 is to adjust the position and position of the elongated rod part when the swing arm 234 swings to the carrying conveying mechanism 220, and the V-shaped groove 233 is used for guiding. In fact, in this embodiment, the telescopic part 231 is electrically connected to the programmable circuit board, and the microprocessor controls the action of the telescopic part 231. The operator can adjust the action parameters of the telescopic part 231 through the operation panel.

[0055] In order to stabilize the clamping of the elongated rod part, the swing arm 234 is provided with two sets, and the two sets of swing arms 234 are respectively arranged on both ends of the swing shaft 232, and each set of swing arms 234 is provided with the clamping wheel 235. Among them, the clamping wheels 235 on the two sets of swing arms 234 can clamp the elongated rod part in cooperation with the carrying conveying mechanism 220, thereby improving the stability and reliability of clamping.

[0056] Further referring to Figures 7 to 8The positioning device 240 comprises a limiting blanking groove 241 and a discharging cylinder 242. The limiting blanking groove 241 is installed above the load wheel 223 at the output end of the receiving conveying mechanism 220 of the rack 210, and is provided with a V-shaped opening in cross section. The discharging cylinder 242 is installed on the bottom side of the end of the limiting blanking groove 241 away from the receiving conveying mechanism 220, and the pinch plane formed between the load wheel 223 and the pinch mechanism 230 is arranged in the same plane as the axis of the discharging cylinder 242. The limiting blanking groove 241 is parallel to the falling direction of the elongated rod member in the opening direction, and the V-shaped opening facilitates the automatic alignment of the elongated rod member during falling. In addition, the main function of the discharging cylinder 242 is to facilitate the positioning of the output elongated rod member and improve the output accuracy of the elongated rod member, which is beneficial to the polishing of the polishing equipment 300. It should be particularly pointed out that in the embodiment, the outer end of the discharging cylinder 242 is directly communicated with the feeding port of the polishing equipment 300, so that the elongated rod member clamped and conveyed by the load wheel 223 and the pinch mechanism 230 can enter the polishing equipment 300.

[0057] Further referring to Figure 1 、 Figure 2 、 Figures 9 to 12 After the elongated rod member is polished in the polishing equipment 300, the elongated rod member is prone to shaking due to friction between the elongated rod member and the polishing structure in the polishing equipment 300 during polishing. In addition, the elongated rod member has a large length-diameter ratio and is flexible. Therefore, in order to reduce the shaking of the processed elongated rod member and ensure the stability of the elongated rod member, the discharging receiving equipment 400 is used to receive and limit the shaking of the elongated rod member. In an embodiment of the present application, the discharging receiving equipment 400 comprises a positioning receiving device 410 and a receiving and stacking device 420. The positioning receiving device 410 is used to clamp and convey the elongated rod member polished and discharged by the polishing equipment 300. The receiving and stacking device 420 comprises a receiving inclined plate 421, a receiving conveying platform 423 and a limiting baffle 424. The receiving inclined plate 421 is obliquely installed at one end of the receiving conveying platform 423, and the projection of the slope direction of the receiving inclined plate 421 on the horizontal plane is parallel to the conveying direction of the receiving conveying platform 423. One side of the receiving conveying platform 423 is connected with the positioning receiving device 410, and the limiting baffle 424 is installed on the side of the receiving conveying platform 423 away from the positioning receiving device 410. The control system 500 is electrically connected with the positioning receiving device 410 and the receiving conveying platform 423.

[0058] The positioning and receiving device 410 plays a role in stabilizing the elongated rod member and also connects the polishing equipment and the receiving and stacking device 420. In addition, the receiving inclined plate 421 and the limiting baffle 424 constitute a receiving and limiting function of the displacement of the elongated rod member. In actual use, the elongated rod member output by the positioning and receiving device 410 will inevitably have a certain inertia, and the limiting baffle 424 is used to block the forward conveying of the elongated rod member and to stop and block the elongated rod member. The inclined slope surface of the receiving inclined plate 421 is arranged to enable the elongated rod member to naturally roll into the receiving and conveying platform 423 due to its own weight, which can adjust the posture of the elongated rod member to some extent, and is more regular than the mode of directly stopping and falling into the receiving and conveying platform 423 by using the limiting baffle 424, which is also conducive to the conveying and stacking of the elongated rod member by the receiving and conveying platform 423.

[0059] Referring to Figure 9 and Figure 10 In the present application, the positioning and receiving device 410 can adopt the sealing strip clamping mechanism disclosed in the patent with publication number CN217992685U. In the present application, the elongated rod member has a relatively large length-diameter ratio, and is prone to bending and deformation under stress. Therefore, when the elongated rod member passes through the polishing equipment 300, both ends thereof can be located outside the polishing equipment 300. Therefore, in order to stabilize the elongated rod member and prevent the end extending out of the polishing equipment 300 from shaking, the positioning and receiving device 410 comprises a bracket 411, a clamping motor 412, a limiting plate 413, and a clamping chain 414 rotatably arranged on the bracket 411. The output end of the clamping motor 412 is connected to the rotation center of one end of the clamping chain 414 through a belt. The limiting plate 413 is installed on the bracket 411 and located above the clamping chain 414. The limiting plate 413 cooperates with the clamping chain 414 to form a clamping space for clamping the elongated rod member. One end of the bracket 411 is provided with a feeding pipe 415, one end of which is in communication with the clamping space and the other end is in communication with the output end of the polishing equipment 300. The cross section of the limiting plate 413 is U-shaped, so that the limiting plate 413 is reversely buckled on the clamping chain 414 to form a closed clamping space, which is conducive to the conveying of the elongated rod member and prevents the elongated rod member from shaking. The clamping motor 412 is electrically connected to the programmable control board in the control system 500.

[0060] Referring to Figure 11 and Figure 12In the present application, the receiving and conveying platform 423 can adopt a conventional chain, a belt or a movable receiving hopper to carry the elongated rod member clamped and conveyed by the positioning and receiving device 410. In an embodiment of the present application, the receiving and conveying platform 423 comprises a main frame 422, two receiving chains 425 rotatably mounted on two sides of the main frame 422, a rotating main shaft 427 connecting the rotation centers of the same ends of the two receiving chains 425, a stacking motor 426 mounted on the main frame 422 and having an output end connected to the rotating main shaft 427 through a belt, a receiving inclined plate 421 mounted on one end of the main frame 422, one side of the main frame 422 connected to the positioning and receiving device 410, and a limiting baffle 424 mounted on the side of the main frame 422 away from the positioning and receiving device 410. The two ends of the main frame 422 are provided with gears, the receiving chains 425 are wound around the two gears, and the area of the main frame 422 between the two gears is provided with a receiving support plate for supporting the receiving chains 425. Of course, a plurality of support wheels can also be provided on the main frame 422 to support the receiving chains 425. The stacking motor 426 is also electrically connected to the programmable circuit board in the control system 500 through a data line, and the microprocessor controls the action of the stacking motor 426.

[0061] In order to better realize the counting and metering of the divided stacks, in some embodiments of the present application, a plurality of mounting blocks 428 are provided on the receiving chains 425, a partition rod 429 is mounted on each mounting block 428, and a carrying space is formed between two adjacent partition rods 429. The mounting blocks 428 can be provided with clamping positions, and the partition rods 429 are inserted into the clamping positions. In this way, the staff can adjust the distance between two adjacent partition rods 429 according to the requirements to adapt to the stacking of different quantities.

[0062] It should be particularly noted that the limiting baffle 424 is provided on the side close to the main frame 421 with a sensor for counting the number of elongated rod members. The sensor is used to detect the number of elongated rod members output by the positioning and receiving device 410, avoiding the trouble of subsequent operators counting. In addition, in actual use, the sensor is electrically connected to the programmable circuit board in the control system 500, and the control system 500 controls the rotation of the stacking motor 426 according to the number detected by the sensor.

[0063] The above embodiments are only preferred embodiments of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and replacements made by those skilled in the art based on the present application are within the scope of protection of the present application.
