Description

Technical Field

[0001] The invention relates to the technical field of PC prefabricated part processing, and in particular to a PC prefabricated wallboard mold closing and cleaning integrated device. Background Art

[0002] With the accelerated advancement of the construction industrialization process, prefabricated buildings have gradually become the mainstream trend in the construction industry due to their significant advantages in standardized design, factory production and integrated decoration. PC (Prefabricated Concrete) components, as an important part of prefabricated buildings, such as prefabricated reinforced concrete columns and prefabricated walls, require the use of professional mold tables for batch production during the production process.

[0003] However, the traditional PC prefabricated component mold table still has many shortcomings in terms of mold clamping, cleaning, demoulding and transportation. For example, a PC prefabricated wall mold clamping device with publication number CN222178135U uses a cleaning mechanism to cooperate with a pressing plate to press the concrete. Although it can achieve all-round and uniform force on the pressing plate and scrape and clean the concrete adhered to the surface to improve the use effect of the device, it cannot simultaneously clean the inner wall of the mold and the concrete dropped on the pressing plate. It is necessary to clean the mold additionally, which makes the cleaning steps more cumbersome. In addition, it is difficult to achieve automatic demoulding and transportation after demoulding, thereby reducing the processing efficiency of PC prefabricated wall panels. Summary of the invention

In addition, in combination with the auxiliary limiting sleeve, the wire brush can be prevented from being thrown out and contacting and hitting the protrusions during mold closing vibration and demolding vibration, thereby further improving the service life of the wire brush.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0038] Example 1: Please refer to Figure 1-Figure 8 As shown, the following solutions can be used to solve the problems of difficulty in fully cleaning the mold, inability to automatically demould and transport the PC prefabricated wall, and reduced processing efficiency and quality;

[0039] In this embodiment, a PC prefabricated wall panel mold cleaning integrated device includes a frame 1, a pressing plate 11 is fixedly connected to the top of the frame 1, an exhaust port (not shown) is opened through the top of the pressing plate 11, and a blocking rod (not shown) is sealed and slidable in the exhaust port, and the blocking rod can be controlled by an electric push rod to open or block the exhaust port, so that the excess air in the mold frame 12 can be discharged before the mold is closed and pressed, thereby improving the processing quality of the PC prefabricated wall panel, and a mold frame 12 is arranged below the pressing plate 11, and a bottom plate 13 is slidably connected to the mold frame 12;

[0040] A fixed amount of concrete is added into the mold frame 12, and the mold frame 12 is carried upward by the bottom plate 13 to move upward, so that the pressing plate 11 contacts the mold frame 12, and then the bottom plate 13 continues to rise, so that the bottom plate 13 moves upward in the mold frame 12, so that the concrete contacts the pressing plate 11 and combines with the mold frame 12 to complete the mold extrusion to prepare the PC prefabricated wallboard, and after the preparation is completed, the PC prefabricated wallboard can be pushed out of the mold frame 12 to achieve the demoulding effect through the movement of the bottom plate 13 in the mold frame 12. The frame 1 is provided with a driving unit 2 for driving the mold frame 12 to move in multiple directions, which is used to realize the motion processing of the bottom plate 13 combined with lifting and turning, and a conveying unit 3 for conveying the PC prefabricated wallboard, and a step-by-step cleaning unit 4 is provided on the mold frame 12;

[0041] The driving unit 2 includes a T-shaped frame 21 fixed to the bottom of the bottom plate 13, and the two sides of the T-shaped frame 21 are rotatably connected with a movable frame 22 that slides with the frame 1. The movable frame 22 is lifted and lowered on the frame 1, and the T-shaped frame 21 carries the bottom plate 13 and the mold frame 12 to move synchronously, and the bottom plate 13 moves independently in the mold frame 12. The step-by-step cleaning unit 4 includes a blocking roller 41, and a plurality of accommodating cavities 1 and accommodating cavities 2 are opened on the annular outer wall of the blocking roller 41. A wire brush 42 is slidably connected in the accommodating cavity 1.

[0042] After the preparation of the PC prefabricated wall panels is completed, the bottom plate 13 carries the mold frame 12 to move downward until the bottom of the pressing plate 11 is higher than the top of the blocking roller 41. The bottom plate 13 stops descending, and the blocking roller 41 carries the wire brush 42 to rotate and move horizontally under the pressing plate 11 in combination with the blocking roller 41 to first clean the concrete at the bottom of the pressing plate 11. A plurality of knocking rods 43 are provided in the second accommodating chamber.

[0043] A plurality of reset springs 14 are fixedly connected between the bottom of the bottom plate 13 and the mold frame 12. The reset springs 14 are arranged so that the bottom plate 13 can drive the mold frame 12 to move synchronously while the bottom plate 13 is lifted and lowered, and when the mold frame 12 is hindered from moving, the bottom plate 13 moves independently in the mold frame 12, so as to realize the mold closing and pressing processing of the PC prefabricated wallboard and the demoulding process;

[0044] One side of the frame 1 is fixedly connected to a guide rod 15 that slides with the corresponding movable frame 22, and the other side of the frame 1 is rotatably connected to a screw rod 16 that is threadedly connected to the corresponding movable frame 22. A motor 1 that drives the screw rod 16 to rotate is installed on the frame 1 through bolts. The motor drives the screw rod 16 to rotate, and the combination of the movable frame 22 and the guide rod 15 causes the T-frame 21 to carry the base plate 13 to perform lifting movements.

[0045] L-shaped guide rods 23 are fixedly connected to both ends of the T-shaped frame 21, and a vertical limit groove 24 is provided on the side wall of the frame 1, and a V-shaped guide groove 25 is provided in the middle of the vertical limit groove 24. When the bottom plate 13 moves up and down, the L-shaped guide rods 23 slide in the vertical limit groove 24 to limit the deflection of the T-shaped frame 21 and prevent the concrete from flowing out before the mold is closed. The mold frame 12 moves up and down synchronously under the drive of the reset tension spring 14.

[0046] After the surface of the pressing plate 11 is cleaned, the blocking roller 41 is stopped at the upper middle part of the mold frame 12, the bottom plate 13 carries the mold frame 12 to move downward, and the L-shaped guide rod 23 enters the V-shaped guide groove 25 from the vertical limiting groove 24 above, thereby causing the T-shaped frame 21 to carry the bottom plate 13 and the mold frame 12 to flip 180 degrees, so that the top opening of the mold frame 12 is downward, and the concrete that has been cleaned on the surface of the pressing plate 11 and dropped into the mold frame 12 can be discharged, and the blocking roller 41 is used to assist in preventing the demoulding of the PC prefabricated wallboard from falling at a higher position and being damaged;

[0047] After flipping, the bottom plate 13 is removed from the mold frame 12, and the rotating blocking roller 41 is moved horizontally to clean the concrete on the surface of the bottom plate 13. In the process of removing, the concrete on the inner wall of the mold frame 12 is scraped and cleaned with the help of the bottom plate 13, thereby achieving the integrated processing of mold preparation, automatic demoulding and transportation, and step-by-step comprehensive cleaning of the mold after demoulding for the PC prefabricated wall panel.

[0048] The top of both sides of the mold frame 12 are fixedly connected with slides 45, and the two groups of slides 45 are rotatably connected with screw rods 46 and spline shafts 47 respectively. Motor 2 for driving the corresponding screw rods 46 and spline shafts 47 to rotate is installed on the slide 45 through bolts. A driving seat 48 and an auxiliary seat 49 for sliding with the slide 45 are rotatably installed at both ends of the blocking roller 41. The driving seat 48 and the auxiliary seat 49 slide in the corresponding slide 45 to drive the blocking roller 41 to move on the surface of the mold frame 12.

[0049] The driving seat 48 is threadedly connected to the screw rod 46, the auxiliary seat 49 is rotatably connected to a sleeve 410 that slides with the spline shaft 47, the sleeve 410 is fixedly connected to an orthogonal bevel gear 1 411, and the roller shaft of the blocking roller 41 is fixedly connected to an orthogonal bevel gear 2 412 that meshes with the orthogonal bevel gear 1 411;

[0050] Through the setting of the orthogonal bevel gear 1 411 and the orthogonal bevel gear 2 412, the spline shaft 47 and the blocking roller 41 can be vertically distributed. The spline shaft 47 is driven to rotate by the corresponding motor 2, and the spline shaft 47 drives the sleeve 410 to rotate. The sleeve 410 drives the blocking roller 41 located on one side of the mold frame 12 to rotate rapidly through the meshing orthogonal bevel gear 1 411 and the orthogonal bevel gear 2 412. The corresponding motor 2 drives the screw rod 2 46 to rotate, and the driving seat 48 drives the rotating blocking roller 41 to move horizontally on the surface of the mold frame 12 to complete the cleaning and flipping blocking process.

[0051] The conveying unit 3 includes a conveying platform 31, and a chain conveyor 32 is installed inside the conveying platform 31 for conveying the demoulded PC prefabricated wallboard. A guide seat that slides with the frame 1 is fixedly connected to the conveying platform 31 to increase the stability of the conveying platform 31 during the lifting process. A lifting electric push rod 33 is fixedly connected between the bottom of the conveying platform 31 and the frame 1.

[0052] By lifting the electric push rod 33 to drive the conveying platform 31 to move upward, the PC prefabricated wall panels and the cleaned concrete can be transported in layers to improve the convenience of collecting the concrete. A resistance plate 34 is fixedly connected to the top of one side of the conveying platform 31 to assist the relative movement between the mold frame 12 and the bottom plate 13, thereby prompting the bottom plate 13 to push the PC prefabricated wall panels out of the mold frame 12 for demoulding.

[0053] By lifting the electric push rod 33, the conveying platform 31 is driven to move upward, the resistance plate 34 contacts the mold frame 12, and pushes the mold frame 12 to move upward. When the bottom plate 13 or the blocking roller 41 is about to contact the PC prefabricated wall panel, the screw rod 46 rotates to drive the blocking roller 41 to move to one side of the mold frame 12, and then the PC prefabricated wall panel is pushed out of the mold frame 12 through the continuous upward movement of the conveying platform 31.

[0054] Example 2: Please refer to Figure 5-Figure 11 As shown, the following solution can be used to solve the problem that when the mold frame is turned over, the demoulding PC prefabricated wall panel extrusion wire brush is bent, which affects the subsequent mold cleaning effect;

[0055] In this embodiment, a plurality of reset springs 44 are fixedly connected between the wire brush 42 and the accommodating chamber 1. By setting the accommodating chamber 1 and the reset springs 44, when the blocking roller 41 does not rotate, it is retracted into the accommodating chamber 1 under the tensile action of the reset springs 44, so that when the blocking roller 41 restricts the PC prefabricated wallboard from falling, the problem of bending of the wire brush 42 due to the squeezing of the PC prefabricated wallboard and affecting the cleaning effect of the mold is avoided;

[0056] A cross bar that rotates with the knocking rod 43 is fixedly connected in the second accommodating chamber, which is used for rotatably installing the knocking rod 43 and preventing the knocking rod 43 from interfering with the rotation of the blocking roller 41. When the blocking roller 41 rotates, the centrifugal force of the rotation causes the wire brush 42 to be thrown out of the first accommodating chamber and stretch the second reset spring 44, thereby cleaning the concrete at the bottom of the pressure plate 11 and impacting the pressure plate 11 with the help of the knocking rod 43 that is thrown out, thereby helping to improve the cleaning effect of the pressure plate 11.

[0057] A transmission plate 17 is fixedly connected to the top of one side of the mold frame 12, and the free side of the transmission plate 17 is an arc-shaped structure. A plurality of knocking protrusions cooperating with the knocking rod 43 are fixedly connected to the arc-shaped inner side of the transmission plate 17. During the extrusion preparation process of the PC prefabricated wallboard, the knocking rod 43 is thrown out from the second accommodating chamber by means of the rotating centrifugal force of the blocking roller 41, and hits the plurality of knocking protrusions on the transmission plate 17, so that the transmission plate 17 forms a high-frequency vibration effect, and transmits the vibration to the mold frame 12, so as to promote the uniform distribution of concrete inside the mold frame 12 and improve the use strength of the finished PC prefabricated wallboard;

[0058] After the preparation of the PC prefabricated wall panel is completed, the motor drives the screw rod 16 to rotate, and the movable frame 22 and the guide rod 15 are combined to cause the T-frame 21 to carry the bottom plate 13 to move downward, and enter the V-shaped guide groove 25 from the upper vertical limit groove 24 through the L-shaped guide rod 23, thereby causing the T-frame 21 to carry the bottom plate 13 and the mold frame 12 to flip over and demold, and the blocking roller 41 is combined with the rotation to cause the knocking rod 43 to hit the knocking protrusion, thereby realizing the demolding and unloading of the PC prefabricated wall panel, and the bottom plate 13 is moved out of the mold frame 12, and the blocking roller 41 carries the knocking rod 43 to hit the bottom plate 13, which promotes the cleaning effect of the concrete on the surface of the bottom plate 13.

[0059] Auxiliary limiting sleeves 413 are provided at both ends of the blocking roller 41, and the annular inner wall of the auxiliary limiting sleeve 413 is a frustum structure, and both ends of the wire brush 42 are fixedly connected with a bending plate that slides with the blocking roller 41, and a universal ball rolling on the inner wall of the auxiliary limiting sleeve 413 is installed at one end of the bending plate. When the blocking roller 41 is located on the transmission plate 17, the two groups of auxiliary limiting sleeves 413 move relative to each other, and through the frustum structure of the inner wall thereof, combined with the bending plate and the universal ball, the wire brush 42 is restricted from being thrown out of the accommodating cavity and contacting and knocking the protrusion, so as to extend the service life of the wire brush 42, and the universal ball avoids increasing the rotation resistance of the blocking roller 41 at this time.

[0060] The driving seat 48 and the auxiliary seat 49 are both slidably connected with two sets of slide bars fixedly connected with the corresponding auxiliary limit sleeves 413. The slide bars are used for the movable installation of the auxiliary limit sleeves 413. The bottom of the auxiliary limit sleeves 413 is fixedly connected with a guide pin 414. The top of the slide seat 45 is provided with a Z-shaped guide groove 415.

[0061] When the blocking roller 41 moves from the transmission plate 17 to the top of the mold frame 12, the Z-shaped guide groove 415 guides the guide pin 414, so that the auxiliary limiting sleeve 413 moves away from the blocking roller 41. Combined with the frustum structure of the inner wall of the auxiliary limiting sleeve 413, the spacing between the plurality of wire brushes 42 can be gradually increased, so that the rotating centrifugal force of the blocking roller 41 can autonomously cause the wire brush 42 to be thrown out of the accommodating chamber 1.

[0062] In the process of the blocking roller 41 moving from the top of the mold frame 12 to the top of the transmission plate 17, the Z-shaped guide groove 415 guides the guide pin 414, prompting the auxiliary limiting sleeve 413 to move relative to each other, automatically reducing the effect of limiting the spacing between the multiple wire brushes 42.

[0063] Example 3: Please refer to Figure 1-Figure 11 As shown, the present invention also proposes a method for using a PC prefabricated wall panel mold cleaning integrated device, comprising the following steps:

[0064] Step 1: Add a certain amount of concrete into the mold frame 12, and the motor 1 drives the screw 16 to rotate, and the movable frame 22 and the guide rod 15 are combined to cause the T-frame 21 to carry the bottom plate 13 to move upward, and the L-shaped guide rod 23 slides in the vertical limit groove 24 to limit the deflection of the T-frame 21. The mold frame 12 moves upward synchronously under the drive of the reset spring 14, so that the pressing plate 11 is in conflict with the mold frame 12, and then the bottom plate 13 continues to rise, so that the bottom plate 13 moves upward in the mold frame 12, and the reset spring 14 is stretched, so that the concrete contacts the pressing plate 11 and is combined with the mold frame 12 to complete the mold extrusion to prepare the PC prefabricated wallboard;

[0065] Step 2: During the extrusion preparation of the PC prefabricated wallboard, the spline shaft 47 is driven to rotate by the corresponding motor 2, and the spline shaft 47 drives the shaft sleeve 410 to rotate. The shaft sleeve 410 drives the blocking roller 41 located on one side of the mold frame 12 to rotate rapidly through the meshing orthogonal bevel gear 1 411 and the orthogonal bevel gear 2 412. During the rotation of the blocking roller 41, the knocking rod 43 is thrown out from the accommodating chamber 2 by the rotating centrifugal force, and hits the multiple knocking protrusions on the transmission plate 17, so that the transmission plate 17 forms a high-frequency vibration effect, and transmits the vibration to the mold frame 12, so as to promote the uniform distribution of concrete inside the mold frame 12, and improve the use strength of the finished PC prefabricated wallboard. The auxiliary limiting sleeve 413 is combined with the bending plate and the universal ball to limit the wire brush 42 from being thrown out of the accommodating chamber 1, so as to extend the service life of the wire brush 42;

[0066] Step 3: After the PC prefabricated wallboard is prepared, the motor 1 drives the screw 16 to rotate, and the movable frame 22 and the guide rod 15 are combined to cause the T-frame 21 to carry the bottom plate 13 to move downward, the pressing plate 11 is separated from the mold frame 12, and the mold frame 12 is reset relative to the bottom plate 13 until the bottom of the pressing plate 11 is higher than the top of the blocking roller 41, the bottom plate 13 stops descending, the blocking roller 41 rotates, and the corresponding motor 2 drives the screw 2 46 to rotate, and the driving seat 48 drives the rotating blocking roller 41 to rotate on the pressing plate 1 1, and in the process that the blocking roller 41 moves horizontally below the mold frame 12, the guide pin 414 is guided by the Z-shaped guide groove 415, so that the auxiliary limiting sleeve 413 moves away from the blocking roller 41, and the rotating centrifugal force of the blocking roller 41 causes the wire brush 42 to be thrown out from the accommodating chamber 1, and the reset tension spring 2 44 is stretched, so that the concrete at the bottom of the pressing plate 11 is cleaned, and the knocking rod 43 is used to hit the pressing plate 11 to improve the cleaning effect of the pressing plate 11;

[0067] Step 4: After the surface of the pressing plate 11 is cleaned, the blocking roller 41 stops rotating and stops at the top of the mold frame 12. The bottom plate 13 carries the mold frame 12 and continues to move downward. The L-shaped guide rod 23 enters the V-shaped guide groove 25 from the vertical limiting groove 24 above, thereby causing the T-shaped frame 21 to carry the bottom plate 13 and the mold frame 12 to flip 180 degrees, so that the top opening of the mold frame 12 faces downward, and then stops descending. The blocking roller 41 is used to help prevent the PC prefabricated wallboard that is demoulded due to cleaning vibration from falling and being damaged;

[0068] Step 5: Lift the electric push rod 33 to drive the conveying platform 31 to move upward, the contact plate 34 contacts the mold frame 12, and pushes the mold frame 12 to move upward. When the bottom plate 13 or the blocking roller 41 is about to contact the PC prefabricated wallboard, the screw rod 46 rotates to drive the blocking roller 41 to move to one side of the mold frame 12, and then the PC prefabricated wallboard is pushed out of the mold frame 12 through the continuous upward movement of the conveying platform 31. Combined with the rotation of the blocking roller 41, the knocking rod 43 is prompted to hit the knocking protrusion, so as to realize the demoulding and unloading of the PC prefabricated wallboard, and the chain conveyor 32 is started to unload and transport;
