Description

Technical Field

[0001] The present invention relates to the technical field of pipe gallery construction safety, and in particular to a manufacturing device and a manufacturing method for a prefabricated pipe gallery. Background Art

[0002] At present, prefabricated pipe corridors are underground or above-ground pipe corridor structures that are prefabricated in factories and transported to construction sites for assembly. This structure is usually used to centrally lay various municipal utility pipelines, such as electricity, telecommunications, tap water, gas, heat, etc., thereby avoiding interference between different pipelines and improving construction efficiency and safety. Prefabricated pipe corridors use modular design to transfer some of the processes that were originally cast on site to the factory, reducing the difficulty and time of on-site construction, and the quality is usually more controllable. Prefabricated pipe corridors are generally made using molds, that is, concrete is poured in a mold with steel bars tied. After the concrete is poured, it is manually vibrated to remove bubbles and ensure that the concrete is dense, and finally it is cured and demolded.

[0003] With respect to the above-mentioned related technologies, the inventors believe that, during the prefabrication process of the pipe gallery, it is often found that there are still many bubbles in the concrete after vibration, and the bubble removal effect is still poor, which leads to the appearance of low-quality prefabricated pipe gallery.

During the rotation of the gear, when the second ball moves from the lowest end of the arc-shaped ascending section to the arc-shaped transition section, the coating plate rotates circumferentially around the piston rod of the multi-stage cylinder while avoiding the roller and moving vertically upward to the top of the roller. When the second ball moves from the arc-shaped transition section to the lowest point of the arc-shaped descending section, the coating plate rotates circumferentially around the piston rod of the multi-stage cylinder while avoiding the roller and moving vertically downward to the initial height, so that the plate surface of the coating plate faces the inner wall on the other side of the forming mold.

[0015] The present application provides a method for manufacturing a prefabricated pipe gallery using the following technical solution:

[0016] A method for making a prefabricated pipe gallery comprises the following steps:

[0017] Determine the specific size, structural form and material requirements of the prefabricated pipe gallery according to project requirements and pipeline layout;

[0018] Prepare the required steel bars, concrete and other auxiliary materials according to design requirements;

[0019] Prepare concrete, ensuring its strength grade and mix proportion meet design requirements;

[0020] The release agent is evenly applied to the inner side wall and the inner bottom wall of the forming mold by a coating mechanism;

[0021] Pour concrete into the forming mold in layers through the grouting mechanism;

[0022] After pouring, the concrete is cured to ensure that it is fully hardened and reaches the designed strength.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. When prefabricating the pipe gallery, first apply the release agent to the inner surface of the forming mold through the coating mechanism. During operation, first coat the surface of the roller coating component with the release agent, then move the roller coating component to a position close to the inner side wall of one side of the forming mold through the driving component, and then continue to move the roller coating component vertically downward through the driving component, so that the inner side wall of one side of the forming mold can be evenly and fully coated with the release agent. At this time, the state of the driving component is the third state. After the roller coating component is attached to the inner bottom wall of the forming mold, the driving component can be switched from the third state to the fourth state. After switching, the roller coating component will move on the inner bottom wall of the forming mold under the action of the driving component, so that the inner bottom wall of the forming mold can be evenly and fully coated with the release agent. Finally, the driving component can be switched from the fourth state to the third state, and the roller coating component can continue to apply the release agent to the inner side wall of the other side of the forming mold. In this way, the release agent on the inner surface of the forming mold can be coated more evenly, avoiding improper application of the release agent, which may cause bubbles to hang on the inner surface of the forming mold, and thus allowing the release agent to fully form a film, effectively reducing the generation of bubbles when concrete is subsequently injected into the forming mold;

[0025] 2. The coating plate will rotate with the gear after being affected by the rotation of the gear. If it rotates directly, the coating plate will collide with the connecting gap and get stuck. Therefore, in order to avoid the above situation, a connecting rod, a sliding sleeve, an avoidance rod, a telescopic rod, a second spring and an avoidance part are provided. When the coating plate contacts the inner wall of one side of the forming mold, the telescopic rod is in a contracted state and the second spring is also in a compressed state. When the roller moves horizontally on the inner bottom wall of the forming mold from close to the inner wall of one side to close to the inner wall of the other side, the inner wall of one side of the forming mold releases the restriction on the telescopic rod. At this time, the telescopic rod will move horizontally under the elastic force of the second spring and leave the connecting gap, so that the connecting gap will not affect the subsequent rotation of the coating plate. Then, when the roller moves to the inner wall of the other side close to the forming mold, the second ball at the end of the extension bar will contact the inner wall of the other side of the forming mold, and then as the roller continues to move, it will generate thrust on the rack, causing the gear to rotate, and the coating plate will rotate synchronously with the gear. However, due to the restriction of the first ball in the avoidance groove, the coating plate will not rotate horizontally in the circumferential direction, but will first gradually move up during the rotation process, allowing the coating plate to avoid the roller and then gradually move down, so that the final height of the coating plate remains unchanged, but successfully avoids the obstruction of the roller to achieve the normal change of the coating plate position. Of course, when the gear rotates, the torsion spring between the gear and the annular groove will gradually tighten to generate a torsional force. For example, the torsional force of the torsion spring is greater than the sum of the friction force between the gear and the rack and the friction force between the second ball and the avoidance groove. In this way, after the coating is completed and the coating plate is separated from the molding mold, the torsional force of the torsion spring will allow the coating plate to cross the roller again and reset to the initial state for the next use.

DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] The following is further described in conjunction with specific embodiments. Figure 1-Figure 9 The present invention is a manufacturing device for a prefabricated pipe gallery, comprising a forming mold 1, a grouting mechanism 2 and a coating mechanism 3. The grouting mechanism 2 is installed on one side of the forming mold 1 and is used to inject concrete into the forming mold 1. The coating mechanism 3 is installed on the forming mold 1 and is used to coat a release agent on the inner surface of the forming mold 1.

[0040] Exemplarily, the forming mold 1 is a rectangular box with an open top. Further, in order to facilitate the removal of the prefabricated pipe gallery after forming, in other embodiments, the side wall of the forming mold 1 can be set as an opening and closing door.

[0041] At the same time, the grouting mechanism 2 includes a concrete mixing component 21 and a pumping component 22. The pumping component 22 is movably installed between the concrete mixing component 21 and the forming mold 1, and the pumping component 22 has a switchable first state and a second state. When the pumping component 22 is in the first state, the pumping component 22 is away from the forming mold 1. When the pumping component 22 is in the second state, the pumping component 22 pumps the concrete stored in the concrete mixing component 21 into the forming mold 1. Exemplarily, the switching between the first state and the second state can be adaptively changed according to the usage. For example, when it is not necessary to inject concrete into the forming mold 1, the pumping component 22 is adjusted to the first state so that the outlet end of the pumping component 22 is away from the forming mold 1, which avoids the situation that the cleaning task is aggravated due to misoperation of pumping concrete 221 into the already cleaned forming mold 1.

[0042] Furthermore, the coating mechanism 3 includes a frame 31, a driving assembly 32 and a roller coating assembly 33. The frame 31 is installed above the molding die 1, and a gap is left between the frame 31 and the upper end opening of the molding die 1 for the pump outlet end of the pumping assembly 22 to enter. The roller coating assembly 33 is installed on the driving assembly 32. The driving assembly 32 has a third state and a fourth state. When the driving assembly 32 is in the third state, the driving assembly 32 drives the roller coating assembly 33 to fit the inner side wall of the molding die 1 and roll the release agent vertically. When the driving assembly 32 is in the fourth state, the driving assembly 32 drives the roller coating assembly 33 to fit the inner bottom wall of the molding die 1 and roll the release agent horizontally. It is worth noting that the position where the third state and the fourth state of the driving assembly 32 are switched is configured to be at the junction of the inner side wall and the inner bottom wall of the molding die 1.

[0043] On this basis, when the pipe gallery is prefabricated, the release agent is first applied to the inner surface of the forming mold 1 through the coating mechanism 3. During operation, the surface of the roller coating component 33 is first coated with the release agent, and then the roller coating component 33 is moved to a position close to the inner side wall of one side of the forming mold 1 through the driving component 32, and then the roller coating component 33 is vertically moved downward through the driving component 32, so that the inner side wall of one side of the forming mold 1 can be evenly and fully coated with the release agent. At this time, the state of the driving component 32 is the third state. Until the roller coating component 33 is attached to the inner bottom wall of the forming mold 1, the driving component 32 can be switched from the third state to the fourth state. After switching, the roller coating component 33 will move on the inner bottom wall of the forming mold 1 under the action of the driving component 32, so that the inner bottom wall of the forming mold 1 can be evenly and fully coated with the release agent. Finally, the driving component 32 can be switched from the fourth state to the third state, and the roller coating component 33 can continue to apply the release agent to the inner side wall of the other side of the forming mold 1.

[0044] It is worth noting that due to the different models of the molding mold 1, the four side walls of some molding molds 1 need to be coated with release agent. Therefore, two sets of mutually perpendicular driving components 32 and roller coating components 33 can be set on the frame 31, so that the molding mold 1 of this model can be effectively coated with release agent.

[0045] In this way, the release agent on the inner surface of the forming mold 1 can be coated more evenly, avoiding improper application of the release agent, which may cause bubbles to hang on the inner surface of the forming mold 1, thereby allowing the release agent to fully form a film, effectively reducing the generation of bubbles when concrete is subsequently injected into the forming mold 1.

[0046] In some embodiments, Figure 1 As shown, the concrete mixing assembly 21 includes a concrete mixer, and the concrete mixer is more convenient for loading and unloading materials and is easy to move.

[0047] For example, refer to Figure 1 , 2 The pumping assembly 22 includes a concrete pump 221, a pipe body 222 and a first rodless cylinder 223. The concrete pump 221 is connected and installed on the concrete mixing assembly 21, and the pipe body 222 is connected to the pumping end of the concrete pump 221. In this way, after the concrete pump 221 is started, the concrete in the concrete mixer can be directly sprayed out from the pipe mouth end of the pipe body 222, which is beneficial to improving the spraying efficiency of the concrete.

[0048] At the same time, the pipe body 222 includes a telescopic pipe section 2221, a transverse pipe section 2222 and an arc-shaped pipe section 2223. The telescopic pipe section 2221 is connected to the pumping end of the concrete pump 221, one end of the transverse pipe section 2222 is connected to the telescopic pipe section 2221, and the other end is connected to the arc-shaped pipe section 2223. The arc-shaped pipe section 2223 extends obliquely downward; thus, since the arc-shaped pipe section 2223 extends obliquely downward, when the arc-shaped pipe section 2223 is moved to the upper end opening of the forming mold 1, the concrete can be directly sprayed from the concrete through the telescopic pipe section 2221, the transverse pipe section 2222 and the arc-shaped pipe section 2223 into the forming mold 1, which can avoid the concrete from splashing to other places after being sprayed out and causing waste to a certain extent, which is beneficial to improving the utilization rate of the concrete.

[0049] Furthermore, the first rodless cylinder 223 is horizontally installed between the concrete mixing assembly 21 and the forming mold 1, and the moving piston of the first rodless cylinder 223 is connected to the transverse pipe section 2222. When the pumping assembly 22 is in the first state, the moving piston of the first rodless cylinder 223 drives the transverse pipe section 2222 to move horizontally away from the forming mold 1 to drive the arc-shaped pipe section 2223 away from the gap; when the pumping assembly 22 is in the second state, the moving piston of the first rodless cylinder 223 drives the transverse pipe section 2222 to move horizontally close to the forming mold 1 to drive the arc-shaped pipe section 2223 to enter the gap and make the pipe mouth of the arc-shaped pipe section 2223 face the inside of the forming mold 1.

[0050] On this basis, by starting the first rodless cylinder 223, the horizontal position of the transverse pipe section 2222 can be adjusted, which is beneficial to improving the convenience of adjusting the position of the pipe body 222. In addition, since the moving piston of the first rodless cylinder 223 is connected to the transverse pipe section 2222, the moving piston of the first rodless cylinder 223 can support the transverse pipe section 2222, so that the pipe body 222 is not prone to shake too much when conveying concrete, which is beneficial to improving the stability of the concrete input into the forming mold 1. It is worth noting that the telescopic pipe section 2221 is a hose, and the transverse pipe section 2222 and the arc pipe section 2223 are both hard pipes.

[0051] In some embodiments, Figure 2 , 3 As shown, the frame 31 includes support rods 311 and a top plate 312. A support rod 311 is vertically provided at each of the four edges of the forming mold 1. The top plate 312 is horizontally installed on multiple support rods 311 and is located above the upper end opening of the forming mold 1. It is worth noting that there is a gap between the support rods 311 and the top plate 312, which can allow the arc-shaped pipe section 2223 to directly enter.

[0052] At the same time, the driving assembly 32 includes a second rodless cylinder 321 and a multi-stage cylinder 322. The second rodless cylinder 321 is installed in the middle of the bottom surface of the top plate 312, and the length direction of the second rodless cylinder 321 is consistent with the length direction of the molding die 1. Exemplarily, the second rodless cylinder 321 extends horizontally. Further, the multi-stage cylinder 322 is installed on the moving piston of the second rodless cylinder 321, and the piston rod of the multi-stage cylinder 322 extends vertically downward, and the roller coating assembly 33 is installed at the end of the multi-stage cylinder 322 away from the second rodless cylinder 321. In this way, when the second rodless cylinder 321 is started, the second rodless cylinder 321 can drive the roller coating assembly 33 to move in the molding die 1 along the length direction of the molding die 1 to achieve the coating of the release agent on the inner bottom wall of the molding die 1. When the multi-stage cylinder 322 is started, the piston rod of the multi-stage cylinder 322 will extend vertically downward to achieve the coating of the release agent on the inner wall of the molding die 1. Of course, in this application, the second rodless cylinder 321 and the multi-stage cylinder 322 need to be used in conjunction to achieve the best position adjustment effect.

[0053] In some embodiments, reference Figure 2 , 3 The roller coating assembly 33 includes a roller 331, the length of the roller 331 is adapted to the width of the forming mold 1, and the surface of the roller 331 is covered with a sponge cover 3311. Since the sponge cover 3311 has many and small gaps inside, it can store a relatively sufficient release agent to provide sufficient coverage of the inner surface of the forming mold 1 during the rolling process of the roller 331. Of course, during the roller coating process, if the dosage of the release agent is insufficient, the movement of the roller 331 can be stopped, and then the sponge cover 3311 on the surface of the roller 331 can be manually supplemented with the release agent. When supplementing, it is only necessary to supplement some parts of the sponge cover 3311. Due to the characteristics of the sponge cover 3311 having many pores, the release agent can quickly fill the entire sponge cover 3311, and it is also convenient to supplement the sponge cover 3311 with the release agent.

[0054] At the same time, the middle part of the roller 331 has a connection gap 3312, the outer diameter of the roller 331 in the connection gap 3312 is smaller than the outer diameter of other parts of the roller 331, and the piston rod end of the multi-stage cylinder 322 is provided with a collar 3221, which extends into the connection gap 3312 and is rotatably connected to the roller 331. In this way, the roller 331 can be connected to the piston rod of the multi-stage cylinder 322 while achieving normal rotation of the roller 331, so that the piston rod of the multi-stage cylinder 322 will not affect the rolling of the roller 331 too much.

[0055] In some embodiments, Figure 4 , 5As shown, the roller coating assembly 33 also includes a coating plate 332, which is vertically connected to the piston rod of the multi-stage cylinder 322, the width of the coating plate 332 is adapted to the width of the connecting gap 3312, and the coating plate 332 extends from top to bottom and passes through the connecting gap 3312 until it is flush with the bottom of the connecting gap 3312; the plate surface of the coating plate 332 facing away from the connecting gap 3312 is provided with a first sponge block 3221, and the first sponge block 3221 is used to fit with the inner side wall of the molding mold 1 near the connecting gap 3312; the bottom of the coating plate 332 is provided with a second sponge block 3322, and the second sponge block 3322 is used to fit with the inner bottom wall of the molding mold 1 near the connecting gap 3312. Such arrangement allows the first sponge block 3221 on the coating plate 332 to fill the gap on the inner wall of the molding mold 1 facing the connecting gap 3312, that is, when the roller 331 is coating the release agent, the portion of the inner wall of the molding mold 1 facing the connecting gap 3312 cannot be coated with the release agent, and the first sponge block 3221 on the coating plate 332 can move synchronously with the rolling of the roller 331 to supplement the portion that cannot be coated at the connecting gap 3312, which is beneficial to improving the uniformity of the coating of the release agent when the roller 331 is coating the inner wall of the molding mold 1.

[0056] At the same time, when the roller 331 switches from rolling coating on the inner side wall of the molding mold 1 to the inner bottom wall, the presence of the second sponge block 3322 will also synchronously fill the small gap at the connecting gap 3312 facing the bottom of the molding mold 1. That is, when the roller 331 is coating the release agent, a small part of the inner bottom wall of the molding mold 1 facing the connecting gap 3312 cannot be coated with the release agent, while the second sponge block 3322 can directly cover this small part, thereby further improving the coverage rate of the release agent.

[0057] In some embodiments, Figure 5 As shown, the bottom of the collar 3221 is also provided with a floor 4, and the bottom of the floor 4 is covered with a third sponge block 41, and the third sponge block 41 is flush with the second sponge block 3322, and the third sponge block 41 is also used to fit with the inner bottom wall of the molding die 1 near the connecting gap 3312. In this way, the floor 4 can fill the vacant part of the roller 331 located below the connecting gap 3312, and combined with the second sponge block 3322, the vacant part of the roller 331 located below the connecting gap 3312 can be mostly filled, thereby improving the coverage of the roller 331 when applying the release agent, so that bubbles are not easily suspended on the inner surface of the molding die 1, which is beneficial to reduce the generation of bubbles.

[0058] In some embodiments, in combination Figure 4 , 5An automatic steering mechanism 5 is also provided between the coating plate 332 and the piston rod of the multi-stage cylinder 322. The automatic steering mechanism 5 is used to drive the coating plate 332 to rotate circumferentially around the piston rod of the multi-stage cylinder 322 to a position away from each other when the roller 331 moves from the inner side wall on one side to the inner side wall on the other side on the inner bottom wall of the forming mold 1, so that the first sponge block 3221 can be attached to the inner side wall on the other side of the forming mold 1. In this way, the position of the coating plate 332 can be adjusted by the automatic steering mechanism 5, so that the coating plate 332 can realize circumferential rotation when the roller 331 moves to the inner side wall on the other side, and then the coating plate 332 can take on the task of filling the vacancy of the connection gap 3312 on the inner wall on the other side of the forming mold 1. Moreover, compared with providing a coating plate 332 on both sides of the roller 331, the advantage of such a configuration is that the utilization rate of the release agent can be improved, so as to avoid, to a certain extent, the situation where the operator fills the coating plate 332 on one side with the coating agent and then the coating plate 332 on this side cannot be used in the subsequent coating process, which not only achieves the effect of saving resources, but also avoids waste to a great extent.

[0059] For example, Figure 4 , 5 The automatic steering mechanism 5 includes a rotating component 6, a resistance component 7 and an avoidance component 8; wherein the rotating component 6 includes a gear 61 and a torsion spring 62, the piston rod of the multi-stage cylinder 322 has an annular groove, the gear 61 is rotatably sleeved in the annular groove, the coating plate 332 is connected to the gear 61, the torsion spring 62 is sleeved between the annular groove and the gear 61, and when the torsion spring 62 is in a natural state, the coating plate 332 is opposite to the inner side wall of one side of the molding mold 1.

[0060] At the same time, refer to Figure 5 , 6 The abutment assembly 7 includes a rack 71, an extension bar 72 and a first spring 73. A transverse guide rail 3222 is provided on the piston rod of the multi-stage cylinder 322. The rack 71 is laterally movable on the transverse guide rail 3222, and the rack 71 is meshed with the gear 61. In this way, after the rack 71 moves with the roller 331 and abuts against the inner side wall of the other side of the molding die 1, the continued movement of the roller 331 drives the rack 71 to move axially on the transverse guide rail 3222, thereby driving the gear 61 to rotate.

[0061] Furthermore, the rack 71 is provided with an extension groove 711 along its own axial direction, the extension bar 72 is slidably inserted in the extension groove 711, and the first spring 73 is provided in the extension groove 711. For example, one end of the first spring 73 is connected to the end wall of the extension groove 711, and the other end is connected to the end of the extension bar 72, and the first spring 73 always has a tendency to push part of the extension bar 72 out of the extension groove 711, and the elastic force of the first spring 73 is greater than the friction force when the gear 61 and the rack 71 are engaged. After such a configuration, when the extension bar 72 abuts against the inner side wall of the other side of the molding die 1, the rack 71 and the extension bar 72 will move synchronously and will not easily slide relative to each other, that is, the first spring 73 overcomes the abutment force, so that the rack 71 and the extension bar 72 do not slide relative to each other, and the rack 71 drives the gear 61 to rotate. At the same time, a first ball 721 is provided at one end of the extension bar 72 away from the rack 71. The first ball 721 can convert sliding friction into rolling friction, thereby preventing the end of the extension bar 72 from directly contacting the inner wall of the molding mold 1 and damaging the inner wall of the molding mold 1, which is beneficial to reducing the probability of the release agent not being able to be evenly applied due to damage to the inner wall of the molding mold 1; a blocking portion 3223 is also provided on the piston rod of the multi-stage cylinder 322, and the blocking portion 3223 is used to prevent the coating plate 332 from continuing to rotate, so that when the coating plate 332 rotates from the inner wall on one side facing the molding mold 1 to the inner wall on the other side facing the molding mold 1, it remains in the position facing the inner wall on the other side of the molding mold 1.

[0062] Through the above scheme, when the extension bar 72 collides with the inner side wall of the other side of the forming mold 1 with the rolling of the roller 331, the extension bar 72 will move synchronously with the rack 71 to drive the gear 61 to rotate, and then drive the coating plate 332 to rotate, until the coating plate 332 is rotated to the blocking portion 3223, at which time the coating plate 332 can no longer continue to rotate, and the extension bar 72 will move into the rack 71 to compress the first spring 73, which can not only avoid the jamming situation to a certain extent, but also allow the coating plate 332 to achieve stable position rotation. Exemplarily, the meshing point of the rack 71 and the gear 61 and the connection point of the gear 61 and the coating plate 332 are staggered, so that the transmission between the two will not affect each other.

[0063] For example, Figure 7 , 8As shown in FIG. 9 , the avoidance assembly 8 includes a connecting rod 81, a sliding sleeve 82, a avoidance rod 83, a telescopic rod 84, a second spring 85 and a avoidance portion 86. The connecting rod 81 is horizontally connected to the gear 61. The sliding sleeve 82 is vertically arranged at the end of the connecting rod 81. The avoidance rod 83 is vertically slidably inserted in the sliding sleeve 82. The top of the avoidance rod 83 is provided with an anti-slip portion 861. The outer diameter of the anti-slip portion 861 is larger than the inner diameter of the sliding sleeve 82. The sliding sleeve 82 has a notch 82 1, one end of the telescopic rod 84 is connected to the avoidance rod 83 through the notch 821, and the other end extends horizontally and is connected to the coating plate 332, and the second spring 85 is arranged in the telescopic rod 84; when the first sponge block 3221 is in contact with the inner side wall of one side of the forming mold 1, the second spring 85 is in a compressed state, and when the roller 331 moves from the inner side wall of one side to the inner side wall of the other side on the inner bottom wall of the forming mold 1, the second spring 85 pushes the telescopic rod 84 to extend, so that the coating The plate 332 is separated from and horizontally moves away from the connecting gap 3312; the lower end of the avoidance rod 83 is provided with a second ball 831, and the avoidance portion 86 is coaxially arranged on the piston rod of the multi-stage cylinder 322. The surface of the avoidance portion 86 is circumferentially provided with an avoidance groove for the second ball 831 to roll, and the avoidance groove includes an arc-shaped ascending section 862, an arc-shaped transition section 863 and an arc-shaped descending section 864 in sequence. During the rotation of the gear 61, when the second ball 831 moves from the lowest end of the arc-shaped ascending section 862 to the arc-shaped transition section 863, the arc-shaped descending section 864 is rotated. When the arc-shaped transition section 863 is reached, the coating plate 332 rotates circumferentially around the piston rod of the multi-stage cylinder 322 while avoiding the roller 331 and moving vertically upward to the top of the roller 331. When the second ball 831 moves from the arc-shaped transition section 863 to the lowest point of the arc-shaped descending section 864, the coating plate 332 rotates circumferentially around the piston rod of the multi-stage cylinder 322 while avoiding the roller 331 and moving vertically downward to the initial height, so that the plate surface of the coating plate 332 faces the inner wall on the other side of the molding mold 1.

[0064] With such arrangement, the coating plate 332 will rotate with the gear 61 after being affected by the rotation of the gear 61. If it rotates directly, the coating plate 332 will collide with the connection gap 3312 and become stuck. Therefore, in order to avoid the above situation, a connecting rod 81, a sliding sleeve 82, an avoidance rod 83, a telescopic rod 84, a second spring 85 and a avoidance portion 86 are provided. When the coating plate 332 contacts the inner side wall of one side of the forming mold 1, the telescopic rod 84 is in a contracted state, and the second spring 85 is also in a compressed state. When the roller 331 moves horizontally from the inner side wall close to one side to the inner side wall close to the other side on the inner bottom wall of the forming mold 1, the inner side wall of one side of the forming mold 1 releases the restriction on the telescopic rod 84. At this time, the telescopic rod 84 will move horizontally under the elastic force of the second spring 85 and leave the connection gap 3312, so that the connection gap 3312 will not affect the subsequent rotation of the coating plate 332.

[0065] Then, when the roller 331 moves to the inner side wall of the other side close to the forming mold 1, the second ball 831 at the end of the extension bar 72 will contact the inner side wall of the other side of the forming mold 1, and then as the roller 331 continues to move, it will generate thrust on the rack 71, causing the gear 61 to rotate, and at this time, the coating plate 332 will rotate synchronously with the gear 61. However, due to the restriction of the first ball 721 in the avoidance groove, the coating plate 332 will not rotate horizontally, but will first gradually move up during the rotation process, allowing the coating plate 332 to avoid the roller 331 and then gradually move down, so that the final height of the coating plate 332 remains unchanged, but successfully avoids the obstruction of the roller 331, so as to achieve the normal change of the position of the coating plate 332.

[0066] Of course, when the gear 61 rotates, the torsion spring 62 between the gear 61 and the annular groove will gradually tighten and generate a torsion force. For example, the torsion force of the torsion spring 62 is greater than the sum of the friction between the gear 61 and the rack 71 and the friction between the second ball 831 and the avoidance groove. In this way, after the coating is completed and the coating plate 332 is separated from the molding die 1, the torsion force of the torsion spring 62 will allow the coating plate 332 to cross the roller 331 again and return to the initial state for the next use.
