Description

Technical Field

[0001] The invention relates to the technical field of plastic coating equipment, in particular to a high-efficiency continuous plastic coating machine for pillar inner plugs. Background Art

[0002] In the field of agricultural production, farmers usually use wooden or bamboo poles to build racks to help vines and climbing plants grow, such as loofah, lentils and tomatoes. Although these wooden or bamboo poles are environmentally friendly, they will age and break after being exposed to the wind and sun. This is not conducive to plant growth, and they are disposable, wasting a lot of wooden and bamboo poles. In the field of decorative flowers, flower racks are also needed to help flowers take shape.

[0003] Therefore, a kind of pillar specially designed for agricultural production and flower planting has emerged. The pillar includes a fiberglass rod and a plastic layer coated on the fiberglass rod or a steel pipe and a plastic layer coated on the fiberglass rod. Plastic parts are installed at both ends of the pillar respectively so that the entire pillar is coated with plastic; thereby protecting the pillar, enhancing the integrity of the fiberglass tube, and improving the insulation performance and appearance.

[0004] At present, Chinese patent CN 115320122 A provides a fully automatic plastic coating device for pillars, which drops plastic parts on both ends of the pillars, and the telescopic end of the cylinder at one end of the pillar moves horizontally to push the plastic parts and the pillars; at the same time, the telescopic end of the cylinder at the other end of the pillar moves downward to support the plastic parts and the other end of the pillar, so that the pillar and the plastic parts on both sides are automatically plugged in; automatic assembly is achieved, and then the telescopic end of the cylinder at the other end of the pillar moves upward again, so that the conveying mechanism can convey the assembled pillars out, and then continue to load the plastic parts and the pillars; although the device can achieve automatic assembly, the assembly process needs to control the frequent up and down movement of the telescopic end of the cylinder, which becomes a bottleneck restricting the improvement of assembly efficiency; therefore, we propose a pillar plug high-efficiency continuous plastic coating machine to further improve the overall assembly efficiency.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0044] See also Figure 1-Figure 13 The present invention provides a high-efficiency continuous plastic packaging machine for pillar inner plugs, comprising a frame 1, on which a pushing mechanism 2, a round tube feeding mechanism 3, an accessory feeding mechanism 4, a conveying mechanism, a first guiding mechanism 6, a thermoplastic mechanism 7, an embossing mechanism 8, a cooling mechanism 9, a second guiding mechanism 10 and a follow-up cutting mechanism 11 are sequentially arranged, and the conveying mechanism comprises a first conveying mechanism 5 and a second conveying mechanism 12. Among them, the pushing mechanism 2 comprises a first fixed plate 201, which is mounted on the frame 1, and the first fixed plate 201 is mounted with a first cylinder 202 through a cylinder mounting plate, and the output end of the first cylinder 202 is fixedly connected with a tube pushing baffle 203, and two limit plates 204 are sequentially arranged in front of the tube pushing baffle 203, and the limit plates 204 are provided with V-shaped grooves, and the limit plates 204 are located directly below the front end of the round tube feeding mechanism 3.

[0045] See also Figure 1-Figure 5 The round tube feeding mechanism 3 includes two wall panels 301 arranged opposite to each other, and the wall panels 301 are installed on the frame 1. An inclined material placing plate 302 is installed on the opposite side of the wall panels 301, and the round tube 303 is placed on the material placing plate 302. The round tube 303 slides down along the material placing plate 302 under the action of gravity. The end of the material placing plate 302 is connected to a second fixing plate 305 through a connecting frame 304, and the lower surface of the second fixing plate 305 is sequentially installed with a second cylinder 306 and a third cylinder 308, and the output end of the second cylinder 306 is fixedly connected to a pressing plate 307, and the output end of the third cylinder 308 is fixedly connected to a stop rod 309. When the third cylinder 308 drives the blocking rod 309 to move downward, the blocking rod 309 abuts against the round tube 303, which can prevent the round tube 303 from sliding out of the material placement plate 302. At the same time, the second cylinder 306 drives the pressing plate 307 to move downward, and after pressing the second round tube 303 at the front end, the third cylinder 308 drives the blocking rod 309 to move upward; the first round tube 303 at the front end of the material placement plate 302 can fall downward onto the limiting plate 204. Therefore, the present application can control the round tubes 303 to fall to the limiting plate 204 in an orderly manner through the cooperation of the second cylinder 306, the third cylinder 308, the pressing plate 307 and the blocking rod 309, so as to avoid multiple round tubes 303 falling to the limiting plate 204 together.

[0046] Preferably, the material placing plate 302 is also provided with silver steel supports extending along the length direction of the material placing plate 302, and both ends of the circular tube 303 are placed on the silver steel supports. The silver steel supports can reduce the friction and resistance when the circular tube 303 slides down, making the circular tube 303 slide down more smoothly.

[0047] See also Figure 1-Figure 2 The accessory feeding mechanism 4 includes a feeding rack 402, and an assembly cylinder 403 is arranged at the bottom end of the feeding rack 402, that is, the bottom end of the feeding rack 402 is connected to the assembly cylinder 403, and the feeding rack 402 contains double-headed inner plugs 401, which are stacked together, and the double-headed inner plugs 401 enter the assembly cylinder 403 in sequence, wherein the structure of the double-headed inner plugs 401 is as follows: Fig.13 shown.

[0048] It should be noted that both ends of the double-headed inner plug 401 are assembled with the round tube 303, so that plastic parts are installed at the end of the round tube 303, thereby obtaining a pillar specially designed for agricultural production and flower planting; when the double-headed inner plug 401 in the assembly tube 403 is separated from the assembly tube 403, the assembly tube 403 at the bottom end of the feeding rack 402 can enter into the assembly tube 403, so that the double-headed inner plug 401 enters the assembly tube 403 in turn.

[0049] It should be further explained that the circular tube 303 of the present application can be a glass fiber tube or a steel tube. The present application does not make any specific limitation and all are within the protection scope of the present application.

[0050] Furthermore, when the round tube 303 falls onto the limiting plate 204, the first cylinder 202 delivers the front end of the round tube 303 into the assembly cylinder 403 at a first travel speed through the tube push baffle 203. At this time, the conveying mechanism delivers another round tube 303 at a second travel speed, wherein the second travel speed is lower than the first travel speed. At this time, there is a double-headed inner plug 401 that falls from the feeding rack 402 between the two round tubes 303. Since the first travel speed is greater than the second travel speed, the round tube 303 behind the double-headed inner plug 401 can push the double-headed inner plug 401 to catch up with the round tube 303 in front, so that both ends of the double-headed inner plug 401 are assembled with the round tube 303, realizing the automatic assembly of the double-headed inner plug 401 and the round tube 303; at this time, the conveying mechanism continues to convey the assembled round tube 303, and when the rear end of the round tube 303 is about to leave the assembly cylinder 403, another double-headed inner plug 401 is taken from the feeding rack 402 falls in, and the first cylinder 202 pushes the front end of another round tube 303 into the assembly cylinder 403 at the first travel speed through the tube push baffle 203, so that both ends of the double-headed inner plug 401 are assembled with the round tube 303 again, so that both ends of the round tube 303 are installed with plastic parts, and the conveying mechanism is always conveying the round tube 303 during the assembly process, so the assembly efficiency is greatly improved, and then the cycle is repeated to assemble both ends of the double-headed inner plug 401 with the round tube 303.

[0051] See also Figure 6 The first conveying mechanism 5 includes two first shaft support plates 503, the first shaft support plate 503 located in the front is rotatably connected with the first upper conveying wheel 501 and the first lower conveying wheel 502, and the first shaft support plate 503 located in the back is rotatably connected with the first upper gear 505 and the first lower gear 506, the first upper gear 505 is connected with the first upper conveying wheel 501, and the first lower gear 506 is connected with the first lower conveying wheel 502.

When the motor drives the first transmission gear 504 to rotate, it will drive the first upper gear 505 and the first lower gear 506 to rotate in the opposite direction, and then drive the first upper conveying wheel 501 and the first lower conveying wheel 502 to rotate in the opposite direction, and the first upper conveying wheel 501 and the first lower conveying wheel 502 together convey the round tube 303 forward.

[0052] See also Figure 2 and Figure 7The second conveying mechanism 12 includes two second shaft support plates 1206. The second shaft support plate 1206 located in the front is slidably matched with a second slider 1203 and is rotatably connected to a second lower conveying wheel 1202.

A spring 1204 is provided between the upper surface of the second slider 1203 and the second shaft support plate 1206. The spring 1204 is used to apply a certain pressure to the second slider 1203 to increase the clamping force between the second upper conveying wheel 1201 and the second lower conveying wheel 1202, thereby increasing the contact friction between the second upper conveying wheel 1201 and the second lower conveying wheel 1202 and the outer wall of the circular tube 303, making it convenient to convey the circular tube 303 forward. A second upper gear 1209 and a second lower gear 1210 are rotatably connected to the second axis support plate 1206 located on the back side. The axle of the second upper conveying wheel 1201 is transmission connected to the second upper gear 1209 through a soft connector 1207. The axle of the second lower conveying wheel 1202 is transmission connected to the second lower gear 1210 through a fixed shaft. The soft connector 1207 is a cross slider connecting shaft. The soft connector 1207 can allow the second upper conveying wheel 1201 to have a certain degree of freedom of movement in the vertical direction relative to the second upper gear 1209. During the process of the second upper conveying wheel 1201 and the second lower conveying wheel 1202 conveying the round tube 303, the second upper conveying wheel 1201 can be displaced less than millimeters in the vertical direction. The second upper gear 1209 is meshed with the second lower gear 1210, one of the second upper gears 1209 is in transmission connection with the encoder 14, and the second upper gears 1209 are in transmission connection with each other through the second transmission gear 1208, one of the second transmission gears 1208 is driven to rotate by a motor, which is not shown in the figure, and the second upper gear 1209 drives the meter wheel of the encoder 14 to rotate, thereby measuring the moving length of the assembled round tube 303 and the double-headed inner plug 401. The encoder 14 is mounted on the third fixed plate 13, the third fixed plate 13 is in the shape of a letter "]", and the third fixed plate 13 is mounted on the second shaft support plate 1206 located on the back.

[0053] Preferably, Figure 3 As shown, a first guiding mechanism 6 is arranged in front of the second conveying mechanism 12. The first guiding mechanism 6 includes an upper pressing wheel 601 and a lower pressing wheel 602. The upper pressing wheel 601 and the lower pressing wheel 602 roll with the outer surface of the round tube 303 to ensure that the round tube 303 remains stable during the conveying process and prevents it from shaking up and down.

[0054] See also Figure 8 The thermoplastic mechanism 7 is used to wrap the assembled circular tube 303 and the double-headed inner plug 401 with plastic film; the thermoplastic mechanism 7 includes a screw barrel 701 connected to the injection molding machine, and a screw rod for conveying molten plastic is arranged inside the screw barrel 701. The screw barrel 701 is connected through a screw barrel connector 702, a die connector 703 and a die head 704, and the die head 704 wraps the assembled circular tube 303 and the double-headed inner plug 401 with plastic film. The screw rod is used to continuously convey the molten plastic from the heating area to the molding area, that is, to continuously convey the heated hot melt plastic to the die head 704, and the assembled circular tube 303 and the double-headed inner plug 401 pass through the die head 704 at the second travel speed, so that the molten plastic can be continuously wrapped on the outer surface of the assembled circular tube 303 and the double-headed inner plug 401, thereby forming a plastic layer.

[0055] Preferably, Fig. 9 and Fig.10 As shown, the inner wall of the die head 704 is provided with a strip groove 7041, so that the outer surface of the assembled round tube 303 and the double-headed inner plug 401 is formed with a plastic convex strip, and the plastic convex strip can increase the friction of the outer surface of the round tube 303, so as to facilitate the climbing plants and climbing plants to climb on it later. There are four strip grooves 7041, which are distributed in an annular manner on the inner wall of the die head 704. An embossing mechanism 8 is provided in front of the thermoplastic mechanism 7; the embossing mechanism 8 includes a first support plate 801, a through hole 802 for the round tube 303 to pass through is provided in the middle of the first support plate 801, and an embossing wheel 804 corresponding to the plastic convex strip is rotatably connected to the first support plate 801 through the second support plate 803, and the number of embossing wheels 804 is set to four, and a plurality of gear teeth are distributed in an annular array on the outer surface of the embossing wheel 804, and the gear teeth of the embossing wheel 804 are used to roll the plastic convex strip. When the round tube 303 with plastic ridges formed on the outer surface passes through the first support plate 801, the plastic ridges combine with the gear teeth on the embossing wheel 804, which will drive the embossing wheel 804 to rotate, and the embossing wheel 804 rolls it at the same time; when the gear teeth of the embossing wheel 804 are separated from the plastic ridges, the embossing wheel 804 continues to rotate under the action of inertia. At this time, the embossing wheel 804 will not press on the plastic ridges to obtain indentations until the next gear tooth contacts the plastic ridges, thereby pressing on the plastic ridges to obtain spaced indentations, making the plastic ridges discontinuous, thereby making the outer surface of the round tube 303 uneven, which is beneficial to increase the friction of the outer surface of the pillar, thereby facilitating vines and climbing plants to climb the pillars in the later stage.

[0056] See also Fig.11The cooling mechanism 9 includes a water tank 901, a connecting pipe 902 and a water tank 903. External cooling water enters the water tank 901 through the water pipe, cools the pillar and flows back to the water tank 903 through the connecting pipe 902. The cooling mechanism 9 cools the pillar after injection molding, helps the plastic to solidify quickly, and can significantly shorten the solidification time of the plastic.

[0057] Preferably, a second guide mechanism 10 is provided in front of the cooling mechanism 9. The second guide mechanism 10 includes four positioning wheels 1001. The positioning wheels 1001 are in rolling cooperation with the outer surface of the round tube 303 to further ensure that the round tube 303 remains stable during transportation and prevents it from shaking up and down.

A fourth cylinder 1105 is carried on one of the first sliders 1104. The bottom end of the fourth cylinder 1105 is rotatably connected to the first slider 1104. The output end of the fourth cylinder 1105 is rotatably connected to a tool holder 1106. The end of the tool holder 1106 away from the fourth cylinder 1105 is rotatably connected to the bottom plate 1108. The blade 1107 is installed on the tool holder 1106.

[0059] It should be noted that the encoder 14 is used to trigger the moving mechanism so that the moving mechanism drives the blade 1107 and the fourth cylinder 1105 to move synchronously with the assembled round tube 303 and the double-headed inner plug 401; at this time, the fourth cylinder 1105 can drive the blade 1107 to approach the double-headed inner plug 401 to cut off the double-headed inner plug 401, so that the round tubes 303 connected to each other through the double-headed inner plug 401 can be separated at the double-headed inner plug 401, ensuring that plastic parts are inserted at both ends of the separated round tubes 303.

[0060] Preferably, see Fig.12The bottom plate 1108 is provided with a clamping plate 1110 through which the assembled round tube 303 and the double-headed inner plug 401 pass. A fifth cylinder 1111 is provided on one side of the clamping plate 1110. When the bottom plate 1108 moves synchronously with the pillar, the telescopic end of the fifth cylinder 1111 is used to extend into the clamping plate 1110 and abut against the outer surface of the assembled round tube 303 and the double-headed inner plug 401, thereby fixing the assembly of the round tube 303 and the double-headed inner plug 401 to prevent shaking or displacement during the cutting process. At this time, the fourth cylinder 1105 is controlled to drive the blade 1107 close to the double-headed inner plug 401. Since the assembled round tube 303 and the double-headed inner plug 401 will not shake during the cutting process, the cutting area can be guaranteed to be flat.

[0061] Working principle of the present invention: the accessory feeding mechanism 4 of the present invention is used to convey the double-headed inner plug 401 into the assembly cylinder 403 in sequence, a plurality of round tubes 303 are placed on the round tube feeding mechanism 3, the round tube feeding mechanism 3 is used to convey the round tubes 303 in sequence to the front of the pushing mechanism 2, the pushing mechanism 2 is used to push the front end of the round tube 303 into the assembly cylinder 403 at a first travel speed, the conveying mechanism is used to convey the round tube 303 out of the assembly cylinder 403 at a second travel speed, the thermoplastic mechanism 7 is used to wrap the assembled round tube 303 and the double-headed inner plug 401 with plastic film; the follow-up cutting mechanism 11 is used to cut off the middle part of the double-headed inner plug 401 so that the multiple round tubes 303 connected together by the double-headed inner plug 401 are separated from each other. After the round tube 303 falls onto the limiting plate 204, the first cylinder 202 feeds the front end of the round tube 303 into the assembling cylinder 403 at a first travel speed. At this time, the conveying mechanism conveys another round tube 303 at a second travel speed. There happens to be a double-headed inner plug 401 that has fallen from the feeding rack 402 between the two round tubes 303. Since the first travel speed is greater than the second travel speed, the round tube 303 behind the double-headed inner plug 401 can push the double-headed inner plug 401 to catch up with the round tube 303 in front, so that both ends of the double-headed inner plug 401 are assembled with the round tube 303, realizing the automatic assembly of the double-headed inner plug 401 and the round tube 303. Moreover, during the assembly process, the conveying mechanism keeps conveying the round tube 303, and the assembly efficiency is greatly improved. After that, the two ends of the double-headed inner plug 401 are assembled with the round tube 303 in a reciprocating cycle. Since the conveying mechanism is connected to the encoder 14 in transmission, the encoder 14 can measure the moving length of the assembled round tube 303 and the double-headed inner plug 401; the encoder 14 triggers the moving mechanism, so that the servo motor 1101 drives the belt 1102 to move synchronously with the assembly of the round tube 303 and the double-headed inner plug 401, and then drives the blade 1107 and the fourth cylinder 1105 to move synchronously with the assembled round tube 303 and the double-headed inner plug 401, and the position of the blade 1107 corresponds to the position of the double-headed inner plug 401; then the telescopic end of the fifth cylinder 1111 is used to extend into the clamping plate 1110 and abut against the outer surface of the assembled round tube 303 and the double-headed inner plug 401, thereby fixing the assembly of the round tube 303 and the double-headed inner plug 401 to prevent shaking or displacement during the cutting process. At this time, the fourth cylinder 1105 is controlled to drive the blade 1107 to approach the double-headed inner plug 401, so that the round tube 303 connected to each other by the double-headed inner plug 401 can be separated at the double-headed inner plug 401, ensuring that plastic parts are inserted at both ends of the separated round tube 303. Since the assembled round tube 303 and the double-headed inner plug 401 will not shake during the cutting process, the cutting area can be guaranteed to be smooth.
