Description

Technical Field

[0001] The present invention relates to the field of column pipe forming and processing equipment, in particular to a tree-grain column forming machine Background Art

[0002] In the construction of amusement facilities and other related amusement buildings, columns, as supporting and decorative elements, are not only required to have sufficient structural strength, but also to visually attract tourists. In recent years, as people's pursuit of the beauty and innovation of amusement facilities continues to increase, various columns with unique appearance designs have begun to be favored by the market.

[0003] The tree pattern pillar is a new type of pillar product developed on this basis. By setting tree-like patterns on the surface of the pillar, it can not only make the appearance of the pillar more unique and beautiful, but also coordinate with the natural environment and enhance the tourists' travel experience.

[0004] When manufacturing tree-grain columns, through specific mold design and material injection process, the material naturally forms tree-like patterns during the solidification process, thereby producing a column product with clear, three-dimensional tree patterns; this method is not only simple to operate and low in cost, but also can greatly improve the appearance quality and market competitiveness of the column products.

[0005] Regarding the above-mentioned related technologies, the column pipe products involved in the tree-grain column forming processing are generally large in size. During the processing, the workpiece transportation is relatively troublesome. If it is all done manually, it will not only consume more manpower and labor, but also affect the workpiece quality and production efficiency. Summary of the invention

[0006] In order to facilitate workers to carry workpieces, improve production efficiency and reduce production costs; the present application provides a tree-grain column forming machine.

[0007] The tree-grain column forming machine provided in this application adopts the following technical solution:

[0008] A tree-grain column forming machine comprises a hoisting frame and an operating platform for hoisting workpieces, the hoisting frame is arranged above the operating platform, and a movable frame is slidably installed on the hoisting frame along the workpiece transportation direction; hooks are arranged on both sides of the movable frame along the workpiece transportation direction, and the hooks are used to be hung on both sides of the workpiece along its own transportation direction, and a winding piece for winding up the hooks is installed on the hoisting frame; an upper mold and a lower mold are arranged on the operating platform, and a working cavity for placing the workpiece is formed between the upper mold and the lower mold, and the inner walls of the upper mold and the lower mold in the working cavity are provided with tree-shaped patterns; a vacuum manufacturing component for evacuating the working cavity is also installed on the operating platform.

[0009] By adopting the above technical solution, the workpiece is first hoisted to the top of the operating platform by the hoisting frame to achieve accurate positioning of the workpiece in three-dimensional space, and then the workpiece is lowered to the working chamber by the hook and the winding piece. After the workpiece enters the working chamber, the upper mold and the lower mold are closed. At this time, the vacuum manufacturing component starts to work and vacuumizes the working chamber to ensure that the material can be evenly distributed under the action of the tree-like texture after injection, and fits tightly to the surface of the workpiece, so as to obtain a column product with clear and three-dimensional tree texture;

[0010] First, through the movable lifting frame and hook design, the workpiece can be automatically and accurately lifted into the working chamber, which greatly reduces the workload of workers in carrying workpieces and improves production efficiency; second, combined with the vacuum operation of the vacuum manufacturing component, it can ensure that the material can be evenly distributed and tightly fit on the surface of the workpiece after injection, forming a clear and three-dimensional tree grain effect, and improving the molding quality of the product; third, the automated operation of the lifting frame also reduces the direct contact between workers and machinery, further improving work safety.

[0011] Preferably, the lower mold is fixedly mounted on the operating platform, the upper mold is rotatably mounted on the operating platform, and a driving assembly for driving the upper mold to rotate on the operating platform is installed on the operating platform; the upper mold is flipped toward the direction close to the lower mold to form the working cavity.

[0012] By adopting the above technical solution, when the workpiece is accurately placed at the predetermined position on the operating platform through the hoisting frame, the driving assembly starts to work, driving the upper die to flip toward the lower die to form a closed working cavity; by flipping the upper die and the lower die to form the working cavity together, the workload of the worker in placing the workpiece into the working cavity is further reduced; the worker only needs to hoist the workpiece to the predetermined position, and the subsequent upper die flipping and working cavity formation process are automatically completed by the machine, which improves work efficiency; secondly, since the direct contact between the worker and the working cavity is reduced during the whole process, the risk of the worker during operation is reduced. Especially when handling large or heavy workpieces, this design can significantly reduce the possibility of worker injury.

[0013] Preferably, pulleys are respectively provided on both sides of the movable frame along the workpiece transport direction, the pulleys are rollingly mounted on the hanging frame, and a driving member for driving the pulleys to roll is mounted on the movable frame.

[0014] By adopting the above technical solution, firstly, the use of the pulley can significantly reduce the friction resistance when the mobile frame slides on the hanging frame, so that the mobile frame can slide more easily and quickly. This not only improves the working efficiency of the machine, but also reduces the heat and wear generated by friction, and prolongs the service life of the equipment; secondly, due to the cooperation of the pulley and the driving member, the mobile frame can be precisely controlled. The driving member can accurately adjust the speed and distance of the pulley rolling according to the preset instructions or the information fed back by the sensor, so as to ensure that the mobile frame can be accurately parked at the predetermined position and realize the precise positioning of the workpiece.

[0015] Preferably, the upper die is provided with the driving assembly on both sides along the workpiece transmission direction; the driving assembly comprises a rotating seat and a driving cylinder, the rotating seat is mounted on the operating platform, and the upper die is rotatably connected to the rotating seat; the driving cylinder is rotatably mounted on the operating platform, and the output end of the driving cylinder is rotatably connected to the upper die. The driving cylinder is connected to a side of the upper die away from the rotating connection.

[0016] By adopting the above technical solution, the upper mold is turned over by using a combination of a rotating seat and a driving cylinder, making the entire turning process fully automated; the worker only needs to start the driving cylinder, and the output rod of the cylinder will shrink, driving the upper mold to rotate on the rotating seat, so that it can be accurately fastened to the lower mold. This not only reduces the labor intensity of the workers, but also improves the automation level of the overall equipment.

[0017] Preferably, the vacuum manufacturing components are arranged on both sides of the operating platform along the workpiece transmission direction; each of the vacuum manufacturing components includes a vacuum seat, a vacuum tube and a vacuum generator; the vacuum seat is installed on the operating platform, one end of the vacuum tube is slidably installed on the vacuum seat toward or away from the working chamber, and the other end is connected to the vacuum generator.

[0018] By adopting the above technical solution, firstly, using the vacuum manufacturing component to create negative pressure in the working chamber can ensure that the material can be evenly distributed in every corner of the working chamber when injected, avoiding material accumulation or voids, thereby improving the molding quality of the product; secondly, since the material can be filled into the working chamber more evenly, the production interruption or rework caused by uneven material distribution can be reduced, thereby improving production efficiency; thirdly, the sliding installation design of the vacuum manufacturing component enables it to flexibly adapt to workpieces and working chambers of different sizes, thereby improving the adaptability and reliability of the equipment.

[0019] Preferably, the upper mold is provided with a first connecting groove along the circumferential direction on the side close to the lower mold after rotation, and the upper mold is provided with a first bag at the first connecting groove, the first bag protrudes out of the first connecting groove and abuts against the lower mold; the lower mold is provided with a second connecting groove along the circumferential direction on the side close to the upper mold, and the lower mold is provided with a second bag at the second connecting groove, the second bag protrudes out of the second connecting groove and abuts against the upper mold; the first connecting groove and the second connecting groove are staggered.

[0020] During the molding process of the tree-grain column, when the upper mold is turned over and close to the lower mold to form a closed working cavity, the material may leak from the gap between the molds during injection. By adopting the above technical solution, when the upper mold is turned over and close to the lower mold, the first bag will first contact and compress the lower mold to form a preliminary seal; as the upper mold continues to rotate, the second bag will also contact and compress the upper mold to further enhance the sealing effect; by improving the sealing between the upper mold and the lower mold, firstly, it can reduce the leakage of material from the gap between the molds during injection, and ensure that the material can be evenly distributed in the working cavity; it helps to reduce production costs and improve the molding quality of the product; secondly, by reducing material leakage, it can reduce the workload of workers in the later stage of tree grain construction.

[0021] Preferably, each vacuum tube is installed with a sealing ring at the pipe mouth close to the working chamber, the upper mold is provided with a first semi-annular sealing groove on one side close to each vacuum seat, and the lower mold is provided with a second semi-annular sealing groove on one side close to each vacuum seat; the sealing ring is inserted into the upper mold through the first sealing groove, and the sealing ring is inserted into the lower mold through the second sealing groove.

[0022] By adopting the above technical solution, when the mold is closed, the sealing ring will be inserted into the first sealing groove and the second sealing groove respectively, so as to seal the gap between the vacuum tube and the mold; first, it is helpful to reduce the leakage of materials from the gap during injection, and ensure that the materials can be evenly filled into the working cavity; second, by reducing material leakage, the workload of workers in the later stage of tree grain construction is further reduced.

[0023] Preferably, guide surfaces are provided on both upper and lower sides of the inner wall of the sealing ring on a side away from the vacuum tube.

[0024] By adopting the above technical solution, firstly, the use of the guide design enables the sealing ring to promote the further close fit between the upper mold and the lower mold during the insertion process, thereby improving the sealing effect between the molds. This helps prevent the material from leaking out from the gap between the molds during injection, ensuring that the material can be evenly filled into the working cavity; secondly, the design of the guide surface makes the insertion process of the sealing ring smoother, reducing the additional adjustments and corrections required by the operator; improving work efficiency and reducing the difficulty of operation.

[0025] Preferably, a first mounting groove is opened in the vertical direction at each rotating seat on the operating platform, a first mounting block is slidably installed at the first mounting groove on the operating platform, a first elastic member is installed between the first mounting block and the first mounting groove, and each rotating seat is respectively installed on a side of the corresponding first mounting block away from the first elastic member; a second mounting groove is opened in the vertical direction at each driving cylinder on the operating platform, a second mounting block is slidably installed at the second mounting groove on the operating platform, a second elastic member is installed between the second mounting block and the second mounting groove, and each driving cylinder is respectively installed on the corresponding second mounting block.

[0026] By adopting the above technical solution, firstly, the mounting block can be fine-tuned in the vertical direction relative to the operating platform, so that the upper mold and the lower mold can fit tightly together when the sealing ring is inserted, thereby improving the sealing effect between the molds; secondly, since the first mounting block and the second mounting block can be fine-tuned in the vertical direction, even if there is a slight misalignment between the upper mold and the lower mold, hard collision and damage can be avoided by fine-tuning. This helps to extend the service life of the equipment.

[0027] Preferably, a trimming platform for trimming the workpiece is provided at the front end of the operating platform along the workpiece transport direction.

[0028] By adopting the above technical solution, workers start the lifting frame to lift the workpiece onto the correction platform to trim the outer surface of the workpiece, making the outer surface of the workpiece smooth and clean, facilitating the attachment of materials to the surface of the workpiece and improving the overall structural stability of the tree grain column.

[0046] Reference Figure 3 and Figure 4 An upper die 21 and a lower die 22 are provided on the operating platform 2, and a working cavity 201 for placing a workpiece is formed between the upper die 21 and the lower die 22. The inner walls of the upper die 21 and the lower die 22 at the working cavity 201 are provided with tree-like patterns. Material is poured into the working cavity 201, and after the material is solidified and formed, tree patterns are formed on the surface of the workpiece under the pressure of the tree-like patterns.

[0047] The lower mold 22 is fixedly installed on the operating platform 2, and the upper mold 21 is rotatably installed on the operating platform 2. A driving component 23 for driving the upper mold 21 to rotate on the operating platform 2 is installed on the operating platform 2; the driving components 23 are arranged on both sides of the upper mold 21 along the workpiece transmission direction; the driving component 23 includes a rotating seat 231 and a driving cylinder 232, the rotating seat 231 is installed on the operating platform 2, and the upper mold 21 is rotatably connected to the rotating seat 231; the driving cylinder 232 is rotatably installed on the operating platform 2, and the output end of the driving cylinder 232 is rotatably connected to the upper mold 21; the driving cylinder 232 is connected to the side of the upper mold 21 away from the rotating connection; the upper mold 21 is flipped toward the lower mold 22 to form a working cavity 201; by the design of flipping the upper mold 21, the degree of automation of mold closing is improved, and the manual operation of workers to close the upper mold 21 and the lower mold 22 is reduced, thereby reducing the possibility of workers being injured when processing large-volume workpieces.

[0048] The movable frame 11 is provided with pulleys on both sides along the workpiece transport direction, and the pulleys are rollingly mounted on the hanging frame 1. A driving member for driving the pulley to roll is mounted on the movable frame 11. In the present embodiment, the driving member is a micro motor, and the driving member is mounted on the movable frame 11 and the output end of the driving member is connected to the pulley. After starting the driving member, the movable frame 11 can be driven to move on the hanging frame 1, and the rotation of the pulley can be accurately controlled by the driving member, thereby controlling the position of the movable frame 11 on the hanging frame 1.

[0049] Reference Figure 3 , vacuum manufacturing components 3 are arranged on both sides of the operating platform 2 along the workpiece transmission direction; each vacuum manufacturing component 3 includes a vacuum seat 32, a vacuum tube 31 and a vacuum generator; the vacuum seat 32 is installed on the operating platform 2, and one end of the vacuum tube 31 is slidably installed on the vacuum seat 32 in the direction close to or away from the working chamber 201, and a movable cylinder 33 is installed on the vacuum seat 32, and the output end of the movable cylinder 33 is connected to the vacuum generator, driving the pipe mouth of the vacuum tube 31 to abut against the side walls of the upper mold 21 and the lower mold 22 located in the working chamber 201, thereby creating negative pressure between the workpiece and the upper mold 21 and the lower mold 22, and then fully injecting the material into the gap between the workpiece and the upper mold 21 and the lower mold 22 to reduce the occurrence of voids.

[0050] Reference Figure 1 The control console 4 is used to control the movement of the hanging frame 1, the lowering of the hook 111 and the injection of materials, so as to facilitate workers to use the column forming machine; a vacuum manufacturing component 3 for evacuating the working chamber 201 is also installed on the operating platform 2.

[0051] The implementation principle of a tree-grain column forming machine in Example 1 of the present application is as follows: a worker operates the control console 4, starts the mobile frame 11 to slide to the top of the workpiece to be hoisted, and then starts the winding piece 112 through the operating table to lower the hook 111. The worker hangs the hook on the workpiece, and then starts the winding piece 112 and the mobile frame 11 to lift the workpiece and transport it to the working chamber 201. At this time, the worker starts the vacuum manufacturing component 3, drives the vacuum tube 31 close to the notch of the working chamber 201, and then the worker injects material into the working chamber 201, and creates negative pressure in the working chamber 201 through the vacuum manufacturing component 3, so that the material can be evenly distributed in various corners between the working chamber 201 and the workpiece during injection, reducing the occurrence of material accumulation or voids; when the material solidifies after a certain period of time, a tree-like pattern can be formed on the workpiece, and the manufacture of the tree-like column is completed.

[0052] Example 2

[0053] The difference between Example 2 of the present application and Example 1 is that, referring to Figure 5 and Figure 6The upper mold 21 is provided with a first connection groove 211 along the circumferential direction on one side close to the lower mold 22 after rotation, and the upper mold 21 is provided with a first bag 212 at the first connection groove 211, the first bag 212 protrudes out of the first connection groove 211 and abuts against the lower mold 22; the lower mold 22 is provided with a second connection groove 221 along the circumferential direction on one side close to the upper mold 21, and the lower mold 22 is provided with a second bag 222 at the second connection groove 221, the second bag 222 protrudes out of the second connection groove 221 And it abuts against the upper mold 21; the first connecting groove 211 and the second connecting groove 221 are staggered; when the upper mold 21 flips over and approaches the lower mold 22, the first bag 212 will first contact and compress with the lower mold 22 to form a preliminary seal; as the upper mold 21 continues to rotate, the second bag 222 will also contact and compress with the upper mold 21, further enhancing the sealing effect, reducing the outflow of material from the gap between the upper mold 21 and the lower mold 22, and reducing the workload of workers when constructing the tree grain in the later stage.

[0054] Reference Figure 6 and Figure 7 A sealing ring 5 is installed at the pipe mouth of each vacuum tube 31 close to the working chamber 201, and guide surfaces 51 are provided on the upper and lower sides of the inner wall of the sealing ring 5 away from the vacuum tube 31; a semi-annular first sealing groove 213 is opened on the side of the upper mold 21 close to each vacuum seat 32, and a semi-annular second sealing groove 223 is opened on the side of the lower mold 22 close to each vacuum seat 32; the sealing ring 5 is inserted into the upper mold 21 through the first sealing groove 213, and the sealing ring 5 is inserted into the lower mold 22 through the second sealing groove 223.

[0055] A first mounting groove 24 is provided at each rotating seat 231 on the operating platform 2 along the vertical direction, a first mounting block 241 is slidably installed at the first mounting groove 24 of the operating platform 2, a first elastic member 242 is installed between the first mounting block 241 and the first mounting groove 24, and each rotating seat 231 is respectively installed on a side of the corresponding first mounting block 241 away from the first elastic member 242; a second mounting groove 25 is provided at each driving cylinder 232 on the operating platform 2 along the vertical direction, a second mounting block 251 is slidably installed at the second mounting groove 25 of the operating platform 2, a second elastic member 252 is installed between the second mounting block 251 and the second mounting groove 25, and each driving cylinder 232 is respectively installed on the corresponding second mounting block 251.

[0056] The working principle of the embodiment 2 of the present application is as follows: the driving cylinder 232 is started to drive the upper mold 21 to flip over so that it is engaged with the lower mold 22. After the sealing ring 5 is inserted into the upper mold 21 and the lower mold 22, the guide surfaces 51 on the upper and lower sides of the sealing ring 5 abut against the upper mold 21 and the lower mold 22, thereby driving the upper mold 21 to move toward the lower mold 22, further reducing the gap between the upper mold 21 and the lower mold 22, and reducing the leakage of the material in the gap at this location; at the same time, because the rotating seat 231 and the driving cylinder 232 of the upper mold 21 are both movably installed on the operating platform 2 in the vertical direction, after the sealing ring 5 is inserted into the upper mold 21 and the lower mold 22, it can drive the upper mold 21 to move stably toward the lower mold 22, reducing the hard collision and damage between the upper mold 21 and the lower mold 22.
