DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] The automatic grouting molding equipment for the production of ceramic flower pots is optimized for the quantitative grouting, vibration defoaming, and internal grouting exhaust in the grouting process of ceramic flower pot production. The basic structure of the equipment is composed of a carrier 1 that carries the mold and a carrier 4 fixed on the surface of the carrier 1.

[0031] The quantitative grouting structure is as follows:

[0032] like Figure 1 , Figure 2 , Figure 6 As shown, the grouting bucket 5 is fixed on the surface of the carrier 4, and a plug disc 51 is slidably adapted and installed in the grouting bucket 5. A variable volume cavity is formed between the plug disc 51 and the bottom end of the grouting bucket 5. The top of the grouting bucket 5 has an exhaust port. A push handle 52 is fixed at the center position of the plug disc 51. The push handle 52 slides through the bottom surface of the grouting bucket 5. A first electric push rod 53 is vertically installed on the outside of the grouting bucket 5. The telescopic end of the first electric push rod 53 is fixedly connected to the push handle 52 through a connecting frame 54. The connecting frame 54 is T-shaped, and both ends of the connecting frame 54 keep vertical sliding with the carrier 4.

[0033] like Figure 7 As shown, a valve assembly 6 is arranged on the bottom surface of the grouting bucket 5, and the valve assembly 6 includes a valve housing 61, and a through-port 62 penetrating the variable volume cavity is provided in the middle of the valve housing 61, and an outlet 63 and an inlet 64 are respectively provided at both ends of the valve housing 61, and the inlet 64 is connected to the mud storage container through a pipeline, and the outlet 63 is connected to the grouting pipe 3 through a hose, and the grouting pipe 3 is arranged above the carrier 1, and a reduced diameter opening 65 is arranged on the side of the through-port 62 close to the outlet 63 inside the valve housing 61, and a first valve plate 66 and a second valve plate 67 are rotatably arranged on the side of the reduced diameter opening 65 close to the outlet 63 and the side of the inlet 64 close to the outlet 63, respectively;

[0034] like Figure 8 As shown, a position switch 9 is installed on the surface of the carrier 4 by screws, the position switch 9 is aligned with the connecting frame 54, and the position switch 9 is connected to the first electric push rod 53 through the controller, and the controller is set to mark the "zero position" of the movement of the first electric push rod 53 at the position where the plug disc 51 is attached to the bottom surface of the grouting bucket 5, that is, the state where the volume of the variable volume chamber is 0;

[0035] The mold is placed on the surface of the carrier 1, and the grouting pipe 3 is aligned downward with the grouting port of the mold. The first electric push rod 53 is in the "zero position" in the initial state. The controller controls the first electric push rod 53 to shrink, so that the push handle 52 pushes the plug disc 51 to rise, and the volume of the variable volume cavity gradually expands to form a negative pressure. At this time, the second valve plate 67 rotates to open the inlet 64 under the action of pressure, and the first valve plate 66 is pressed to close the reduced diameter port 65. The mud in the storage container enters the variable volume cavity through the inlet 64 and the through port 62. When the connecting frame 54 touches the position switch 9, the controller controls the first electric push rod 53 to extend, and the plug disc 51 descends to press the mud in the variable volume cavity into the valve housing 61. At this time, the second valve plate 67 is pressed to close the inlet 64, and the first valve plate 66 is pressed to open the reduced diameter port 65. The mud is transmitted to the grouting pipe 3 through the outlet 63 and injected into the mold until the first electric push rod 53 moves to the "zero position" to complete the grouting. The mold is replaced for continuous grouting.

[0036] By controlling the capacity of the variable volume cavity to be consistent with the mold capacity, the mold grouting amount can be accurately controlled. For the grouting production of different batches of flower pots, the height of the position switch 9 is adjusted according to the specific mold capacity to adjust the volume of the variable volume cavity and meet the grouting production of flower pots of different sizes.

[0037] The structure of vibration defoaming is as follows:

[0038] like Figure 8 , Fig. 9 As shown, a sliding cavity 12 is provided on the surface of the carrier 1, and the carrier plate 11 slides in the sliding cavity 12 elastically through a spring, and fixed tooth plates 81 are symmetrically fixedly installed on both sides of the carrier plate 11, and the connecting frame 54 is symmetrically fixedly installed with a movable tooth plate 8, and the tooth surfaces of the movable tooth plate 8 and the fixed tooth plate 81 are aligned and contacted, and the teeth of the movable tooth plate 8 and the fixed tooth plate 81 are adapted straight teeth, and the tip angle of the straight teeth is greater than 90°;

[0039] like Figure 8 As shown, the positioning assembly 2 includes two brackets 21, which are symmetrically fixed on both sides of the carrier plate 11, and a cylinder 22 is installed on the surface of the bracket 21. A rubber pressing plate 23 is fixed to the telescopic end of the cylinder 22, and an infrared sensor 24 is provided on one side of the carrier plate 11;

[0040] When the mold is placed on the surface of the carrier plate 11, the infrared sensor 24 monitors whether it is in place, and the controller controls the cylinder 22 to extend synchronously so that the two rubber pressure plates 23 clamp the mold. The rubber pressure plates 23 are arc-shaped and can automatically center the mold on the surface of the carrier plate 11. When the first electric push rod 53 extends to drive the plug plate 51 to move down for grouting, the connecting frame 54 drives the movable tooth plate 8 to descend, and the tooth surfaces of the movable tooth plate 8 and the fixed tooth plate 81 contact each other and the elastic force of the carrier plate 11, so that the carrier plate 11 produces continuous shaking, which is used to discharge bubbles in the mud and make the surface quality of the formed flower pot higher.

[0041] The structure of internal grouting exhaust is as follows:

[0042] like Figure 1 , Figure 2 , Figure 5 As shown, the grouting pipe 3 is fixedly connected to the slide 31, the slide 31 slides vertically along the carrier 4, the second electric push rod 32 is vertically installed on the side of the carrier 4, the telescopic end of the second electric push rod 32 is connected to the slide 31, and the bottom of the grouting pipe 3 is sealed and a plurality of material ports 33 are set at the bottom edge;

[0043] When grouting is performed, the second electric push rod 32 contracts to cause the slide 31 to drive the grouting pipe 3 to descend, and the grouting pipe 3 is inserted into the mold. The material port 33 is close to the bottom of the mold, and the mud is sprayed into the mold through the material port 33. Since the grouting part is located at the bottom of the mold, the height of the mud gradually rises from bottom to top, which can smoothly discharge the air in the mold, reduce excessive mixing of the mud with air during injection, and reduce the gas content in the mud.

[0044] like Figure 3 , Figure 4 , Figure 5 As shown, a ring sleeve 7 is slidably sleeved on the outside of the grouting pipe 3, the ring sleeve 7 is connected and fixed to the suspension 71, the suspension 71 slides vertically and elastically with the slide 31 through a spring, the bottom end of the grouting pipe 3 has a truncated cone portion 34 with a gradually increasing diameter, and the bottom of the ring sleeve 7 has a skirt;

[0045] When the grouting pipe 3 is inserted into the mold for grouting, the compression spring between the suspension 71 and the slide 31 slides, so that the ring sleeve 7 is against the top surface of the mold and remains outside the mold. After the grouting is completed, the second electric push rod 32 extends to allow the slide 31 to drive the grouting pipe 3 to move upward, and the grouting pipe 3 is withdrawn from the mold. The surface of the grouting pipe 3 will be covered with mud. During the withdrawal process of the grouting pipe 3, the ring sleeve 7 is always maintained at the top of the mold under the action of elastic force, and the grouting pipe 3 and the ring sleeve 7 will slide. The ring sleeve 7 can scrape off the mud on the surface of the grouting pipe 3 until the grouting pipe 3 is completely withdrawn from the mold. The skirt of the ring sleeve 7 fits the frustum 34 to complete the scraping of all the mud on the side wall of the grouting pipe 3, and the ring sleeve 7 blocks the material port 33 to prevent dripping.

[0046] like Figure 3 , Figure 4As shown, a vertical thread penetrates the screw rod 72 on the surface of the slide 31, and a push switch 73 for positioning the suspension 71 is installed at the bottom of the screw rod 72. The push switch 73 is connected to the second electric push rod 32 through the controller. During grouting, since the suspension 71 and the ring sleeve 7 resist the surface of the mold, the slide 31 pushes the grouting pipe 3 down and inserts it into the mold, and the distance between the slide 31 and the bottom of the suspension 71 gradually decreases. When the push switch 73 touches the suspension 71, the contraction movement of the second electric push rod 32 is stopped, indicating that the grouting pipe 3 is inserted to the preset depth at this time. According to molds of different sizes, the screw rod 72 can be rotated to adjust the height of the push switch 73 to change the touch distance between the push switch 73 and the suspension 71.

[0047] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
