Description

Technical Field

[0001] This invention belongs to the field of brick-making equipment technology, specifically relating to a brick-making machine airbag-type automatic locking and releasing device and method. Background Technology

[0002] Brick machines are divided into two main categories: vacuum brick machines and non-fired brick machines. The former uses soil to make brick blanks, requiring a large amount of soil and thus wasting resources. The latter uses waste coal gangue, shale, stone powder, fly ash, slag, mineral slag, crushed stone, sand, etc., and does not undergo a firing process, making it more environmentally friendly and resource-saving, and has been strongly promoted by the state. Existing brick machines require fixing and limiting the position of the mold before pressing bricks. The earliest fixing and limiting method was to use screws to lock the mold, which was time-consuming and labor-intensive. Later, airbags were used to lock the mold, but airbags could only clamp the mold. To loosen it, the power had to be turned off to allow the airbags to slowly deflate, and manual pressing of the airbags was still required to loosen the clamped block, which was very inconvenient. In view of this, this solution was developed. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by the present invention is to provide a brick machine airbag type automatic locking and releasing device and method, which can automatically lock and release the mold.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a brick machine airbag type automatic locking and releasing device, including two locking and releasing components. The locking and releasing components include a base, an airbag, two pressure rods and a pressure seat. The base is provided with two mounting brackets, which are spaced apart. The middle part of the two pressure rods is rotatably connected to the mounting brackets. The pressure seat is connected to the lower surface of the two pressure rods on the same side. The other end of the two pressure rods is fixedly connected to a synchronizing rod. The airbag is located on the base, and the upper surface of the airbag is fixedly connected to the lower surface of the synchronizing rod.

[0005] Furthermore, the number of airbags is three, and the three airbags are spaced apart.

[0006] Furthermore, a limiting post is provided next to the airbag, the limiting post is connected to the base, and the upper surface of the limiting post is located within the swing path of the synchronizing rod. The limiting post is used to limit the swing angle of the pressure rod.

[0007] Furthermore, the automatic locking and releasing device also includes a mold, the mold having extension plates on both sides, the extension plates having two positioning holes, the lower surface of the pressure seat being connected to a first buffer pad, the base having a second buffer pad corresponding to the pressure seat, the first buffer pad having two first through holes, the second buffer pad having two second through holes, the pressure seat having two first mounting slots, the base having two second mounting slots, the first through holes, the second through holes, the first mounting slots, the second mounting slots, and the positioning holes being vertically aligned;

[0008] The second mounting groove is provided with a ferromagnetic sliding rod, and the first mounting groove has an electrically driven magnetic suction plate; the electrically driven magnetic suction plate drives the ferromagnetic sliding rod to extend between the first through hole and the positioning hole when energized.

[0009] Furthermore, the extension plate is provided with two position calibration holes, which are spaced apart. The first buffer pad has two third through holes, the second buffer pad has two fourth through holes, the pressure seat has two third mounting slots, and the base has two fourth mounting slots. The third through holes, fourth through holes, third mounting slots, fourth mounting slots, and position calibration holes are vertically aligned.

[0010] An infrared generator is installed in the third mounting slot, and an infrared receiver is installed in the fourth mounting slot.

[0011] Furthermore, the second mounting groove includes a receiving portion and a protruding portion. The diameter of the receiving portion is larger than the diameter of the protruding portion. The end of the ferromagnetic sliding rod has a circular boss located inside the receiving portion. The diameter of the circular boss is larger than the diameter of the protruding portion and smaller than or equal to the diameter of the receiving portion.

[0012] Furthermore, the base is provided with a vertical plate, which is located on the inner side of the second buffer pad and below the pressure rod. A third buffer pad is provided on the outer side of the vertical plate.

[0013] Furthermore, the automatic locking and releasing device also includes a pneumatic system, which comprises two solenoid valves, two vacuum generators, two 2-position 2-way pilot-operated solenoid valves, four 3-way adapters, and two 2-way adapters. Each solenoid valve, vacuum generator, 2-position 2-way pilot-operated solenoid valve, two 3-way adapters, and one 2-way adapter is grouped together. One end of the vacuum generator is connected to the solenoid valve, and the other end is connected to the upper end of the 2-position 2-way pilot-operated solenoid valve. The other end of the solenoid valve is connected to the lower end of the 2-position 2-way pilot-operated solenoid valve. The upper end of the two-position two-way pilot-operated solenoid valve is connected to the lower end of the upper three-way adapter, the lower end of the two-position two-way pilot-operated solenoid valve is connected to the upper end of the lower three-way adapter, the lower end of the upper three-way adapter is connected to the upper end of the lower three-way adapter, and the lower end of the lower three-way adapter is connected to the two-way adapter. The two-way adapters in the two groups are interconnected. An air inlet pipe is provided on the connecting pipe between the three-way adapter and the two-way adapter in one group. The upper end of the upper three-way adapter in each group is connected to the outside.

[0014] A method for automatically locking and releasing a brick machine using an airbag system includes the following steps:

[0015] S1. The mold moves below the pressure seat;

[0016] S2. Calibrate the mold position;

[0017] S3, the airbag inflation seat presses down on the extension plate of the mold;

[0018] S4. When changing the mold, the airbag is used to separate the pressure seat and extension plate.

[0019] Furthermore, the specific steps of step S2 are as follows: the airbag inflation seat is pressed onto the extension plate. When the infrared receiver in any of the fourth mounting slots does not receive an infrared signal, it indicates that the mold position is inaccurate. The airbag deflation seat leaves the extension plate, the mold is moved, and the above actions are repeated until the infrared receivers in the two fourth mounting slots receive the signal from the infrared generator in the corresponding third mounting slot.

[0020] Furthermore, the specific steps of step S3 are as follows: the airbag inflation pressure seat is pressed onto the extension plate, the electric drive magnetic suction plate of the first mounting groove is energized, the ferromagnetic sliding rod extends into the space between the first through hole and the positioning hole, and the material feeding vibration pressing begins.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. This invention relates to a brick machine airbag-type automatic locking and releasing device. When the mold moves between two locking and releasing components, the airbag is instantly inflated, and the pressure seat at the end of the control rod moves downward to press the mold, thus achieving automatic locking. Only when the mold is changed, the gas in the airbag is sucked out, and the pressure seat at the end of the control rod is lifted upward, thus achieving automatic releasing. Furthermore, this invention also provides a brick machine airbag-type automatic locking and releasing method, which can automatically calibrate the mold position for pressing and releasing the mold.

[0023] 2. When the pressure seat presses the extension plate of the mold, the first through hole of the first buffer pad, the second through hole of the second buffer pad, the first mounting groove of the pressure seat, the second mounting groove of the base and the positioning hole of the extension plate are aligned vertically. When the electric drive magnetic suction plate is energized, it pulls the ferromagnetic sliding rod into the space between the first through hole and the positioning hole, thus limiting the horizontal position of the mold.

Detailed Implementation

[0031] To make the above features and advantages of the present invention more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0032] like Figure 1-6 As shown, this embodiment provides a brick machine airbag type automatic locking and releasing device, including two locking and releasing components and a mold 5. The mold 5 has extension plates 51 on both sides, and the extension plates 51 have two positioning holes 511. The extension plates 51 are provided with two position calibration holes 512, which are located between the two positioning holes 511.

[0033] The locking / unlocking assembly includes a base 1, an airbag 2, two pressure rods 3, and a pressure seat 4. The base 1 has two mounting brackets 15 spaced apart. The middle of each pressure rod 3 is rotatably connected to a mounting bracket 15. The pressure seat 4 is connected to the lower surface of the two pressure rods 3 on the same side. Specifically, a first buffer pad 41 is connected to the lower surface of the pressure seat 4, and a second buffer pad 11 is provided at a corresponding position on the base 1 and the pressure seat 4. The first buffer pad 41 has two first through holes 411, and the second buffer pad 11 has two second through holes. The pressure seat 4 has two first mounting grooves. The base 1 has two second mounting slots, and the first through hole 411, the second through hole, the first mounting slot, the second mounting slot and the positioning hole 511 are corresponding vertically. A ferromagnetic sliding rod 13 is provided in the second mounting slot. The second mounting slot includes a receiving part 161 and a protruding part 162. The diameter of the receiving part 161 is larger than the diameter of the protruding part 162. The end of the ferromagnetic sliding rod 13 has a circular boss 131. The circular boss 131 is located in the receiving part 161. The diameter of the circular boss 131 is larger than the diameter of the protruding part 162 and smaller than or equal to the diameter of the receiving part 161. The first mounting slot contains an electrically driven magnetic suction plate 43. When the electrically driven magnetic suction plate 43 is energized, it drives the ferromagnetic sliding rod 13 to extend between the first through hole 411 and the positioning hole 511. When the pressure seat 4 presses the extension plate 51 of the mold 5, the first through hole 411 of the first buffer pad 41, the second through hole of the second buffer pad 11, the first mounting slot of the pressure seat 4, the second mounting slot of the base 1, and the positioning hole 511 of the extension plate 51 correspond vertically. When the electrically driven magnetic suction plate 43 is energized, it draws the ferromagnetic sliding rod 13 into the space between the first through hole 411 and the positioning hole 511, thus limiting the horizontal position of the mold 5. Since the ferromagnetic sliding rod 13 is located in the positioning hole 511 and the first through hole 411, the mold 5 can also be appropriately offset in the horizontal direction during vibration. After the vibration ends, it will be reset under the action of the ferromagnetic sliding rod 13 and the first buffer pad 41.

[0034] Preferably, a contact switch 1611 is provided at the bottom of the receiving part 161 for detecting whether the ferromagnetic sliding rod 13 is extended.

[0035] The first buffer pad 41 has two third through holes 412, the second buffer pad 11 has two fourth through holes, the pressure seat 4 has two third mounting slots, and the base 1 has two fourth mounting slots. The third through holes 412, the fourth through holes, the third mounting slots, the fourth mounting slots and the position calibration hole 512 are vertically aligned. An infrared generator 44 is installed in the third mounting slot, and an infrared receiver 14 is installed in the fourth mounting slot.

[0036] Two pressure rods 3 are fixedly connected to a synchronizing rod 31 at the other end. The airbag 2 is located on the base 1. There are three airbags 2, which are spaced apart. The upper surface of the airbag 2 is fixedly connected to the lower surface of the synchronizing rod 31. There is a limiting post 21 next to the airbag 2. The limiting post 21 is located between the two airbags 2 and is connected to the base 1. The upper surface of the limiting post 21 is located within the swing path of the synchronizing rod 31. The limiting post 21 is used to limit the swing angle of the pressure rod 3.

[0037] The pneumatic system used in Airbag 2 is as follows Figure 6 As shown, the pneumatic system includes two solenoid valves, two vacuum generators 61, two two-position two-way pilot-operated solenoid valves 62, four three-way adapters 63 and two two-way adapters 64. The solenoid valves are 4V310-10-DC24V solenoid valves 61, the vacuum generators 61 are vacuum generators CV-20HS, and the two-position two-way pilot-operated solenoid valves 62 are 2V130-15 two-position two-way pilot-operated solenoid valves 62. The system is divided into two groups. Each group consists of a 4V310-10-DC24V solenoid valve 6, a vacuum generator 61, a 2-position 2-way pilot-operated solenoid valve 62, two 3-way adapters 63, and a 2-way adapter 64. One end of the vacuum generator 61 is connected to the 4V310-10-DC24V solenoid valve 6, and the other end is connected to the upper end of the 2-position 2-way pilot-operated solenoid valve 62. The other end of the 4V310-10-DC24V solenoid valve 6 is connected to the lower end of the 2-position 2-way pilot-operated solenoid valve 62. The upper end of the 2-position 2-way pilot-operated solenoid valve 62 is connected to the lower end of the 3-way adapter 63 located above it. The lower end of the solenoid valve 62 is connected to the upper end of the lower three-way adapter 63, the lower end of the upper three-way adapter 63 is connected to the upper end of the lower three-way adapter 63, and the lower end of the lower three-way adapter 63 is connected to the two-way adapter 64. The two-way adapters 64 in the two sets are connected to each other. An air inlet pipe is provided on the connecting pipe between the three-way adapter 63 and the two-way adapter 64 in one set. The upper end of the upper three-way adapter 63 in each set is connected to the outside. The upper end of one three-way adapter 63 is connected to the air bladder, and the upper end of the other three-way adapter 63 is connected to the pressure head air bladder (the pressure air bladder located on the upper mold is not described in detail in this solution).

[0038] The base 1 is also provided with a vertical plate 12, which is located on the inner side of the second buffer pad 11 and below the pressure rod 3. A third buffer pad 121 is provided on the outer side of the vertical plate 12.

[0039] A method for automatically locking and releasing a type 2 airbag in a brick making machine includes the following steps:

[0041] S2, Mold 5 position calibration;

[0042] S3, the airbag 2 is inflated, and the pressure seat 4 presses down on the extension plate 51 of the mold 5;

[0043] S4. When changing the mold, the airbag 2 is used to separate the pressure seat 4 and the extension plate 51.

[0044] The specific steps of steps S1 and S2 are as follows: the airbag 2 inflation seat 4 is pressed onto the extension plate 51. When the infrared receiver 14 in any of the fourth mounting slots does not receive an infrared signal, it indicates that the position of the mold 5 is inaccurate. The airbag 2 deflating seat 4 leaves the extension plate 51, the mold 5 is moved, and the above actions are repeated until the infrared receivers 14 in the two fourth mounting slots receive the signal from the infrared generator 44 in the corresponding third mounting slot.

[0045] The specific steps of steps S3 and S4 are as follows: the airbag 2 is inflated, the pressure seat 4 is pressed onto the extension plate 51, the electric drive magnetic suction plate 43 of the first mounting slot is energized, and the ferromagnetic sliding rod 13 is inserted between the first through hole 411 and the positioning hole 511 to start the material feeding vibration pressing; only when changing the mold, the airbag 2 is deflated to separate the pressure seat 4 and the extension plate 51.
