Description

Technical Field

[0001] This invention mainly relates to the field of screw press processing, specifically an automated assembly device for fixed and moving plates of a screw press. Background Technology

[0002] Screw presses are widely used in municipal wastewater treatment projects and water treatment in industries such as petrochemicals, light industry, chemical fibers, papermaking, pharmaceuticals, and leather. The main body of the dewatering machine consists of stacked fixed and moving blades, with a spiral shaft running through them to form a filtration device. The front section of the screw press is the thickening section, and the rear section is the dewatering section. The filter gaps between the fixed and moving blades, as well as the pitch of the spiral shaft, gradually decrease from the thickening section to the dewatering section. To prevent sludge from clogging the gaps between the moving and fixed blades, the rotation of the spiral shaft typically drives the moving rings to rotate continuously. The equipment achieves a continuous self-cleaning process through the movement between the fixed and moving rings. Screw presses are available in single-shaft and double-shaft structures. In a double-shaft screw press, the two spiral shafts rotate in opposite directions, thus better pushing and displacing the sludge.

[0003] Currently, the assembly of the fixed and moving plates in a screw press mainly relies on manual operation. Workers manually stack the fixed and moving plates alternately, with the fixed plates nested on support columns, and spacers placed on the support columns between the fixed plates. This method is heavily dependent on manual labor, resulting in low assembly efficiency and high assembly costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an automated assembly device for the stationary and moving plates of a screw press, which enables automated assembly of the stationary and moving plates, improving assembly efficiency, reducing the degree of human intervention, and lowering assembly costs.

[0005] To achieve the above objectives, the present invention employs the following technical solution:

[0006] An automated assembly device for stationary and moving plates of a screw press includes a positioning frame, a first stacking seat, and a second stacking seat. The positioning frame is equipped with a lifting system, and the lifting system has corresponding positioning seats. Each positioning seat has several positioning holes. A lifting cylinder is located below the positioning frame, and a lifting mold is located at the front end of the piston rod of the lifting cylinder. The lifting mold has contact heads corresponding to the positioning holes. Both the first and second stacking seats have stacking lifting mechanisms at their bottoms. Positioning grooves are provided on the top surfaces of both the first and second stacking seats, and stacking fixtures are placed within these grooves. Both the first and second stacking seats have lifting channels, and the stacking fixtures have through holes corresponding to these lifting channels. The top of the stacking lifting mechanisms has lifting heads adapted to the lifting channels. A lifting frame is provided between the positioning frame and the tops of the first and second stacking seats. The lifting frame has a lifting rail at its bottom, a lifting timing belt mechanism on one side of the lifting rail, a clamping seat slidingly mounted on the lifting rail, a lifting mechanism at the bottom of the clamping seat, two inner support claw chucks at the bottom of the lifting mechanism, a pad dispensing device on one side of the positioning frame, the pad dispensing device including a dispensing frame, a transverse guide rail and a transverse timing belt mechanism on the dispensing frame, a dispensing seat slidingly mounted on the transverse guide rail, an extension sleeve fixedly mounted on the dispensing seat, an extension slide rail slidingly mounted on the extension sleeve, an extension timing belt mechanism on one side of the extension slide rail, a point on the timing belt of the extension timing belt mechanism fixed to the dispensing seat, a dispenser at the front end of the extension slide rail, a dispensing channel inside the dispenser, a dispensing hole at the bottom front end of the dispensing channel, a pusher at the rear end of the dispensing channel, and a material cylinder at the top rear end of the dispensing channel.

The top of the positioning frame is provided with a first servo motor for driving the first lifting screw to rotate.

[0009] The positioning hole is a countersunk hole, and the diameter of the contact head is the same as the small diameter hole at the bottom of the positioning hole.

[0010] The lifting channel is located below the stacked screw plates, and the top of the lifting head contacts the bottom of the stacked screw plates. Through the lifting action of the stacking lifting mechanism, the topmost stacked screw plate is disengaged from the positioning cylinder.

[0011] The lifting mechanism includes a pair of fixed lifting sleeves and a fixed lead screw nut. A lifting slide rail is slidably arranged inside the lifting sleeves. A second lifting lead screw is fitted inside the fixed lead screw nut. A second servo motor is arranged at the top of the second lifting lead screw. An installation plate is arranged at the bottom of the lifting slide rail. Two inner support claw chucks are arranged at the bottom of the installation plate.

[0012] The clamping seat includes a mounting seat and a drive seat. The drive seat cooperates with the hoisting rail. The lifting mechanism is located at the bottom of the mounting seat. The bottom of the drive seat is provided with a fine-tuning slide rail and a fine-tuning screw.

[0016] This invention automates the assembly of stationary and moving blades in a screw press, improving assembly efficiency, reducing manual intervention, and lowering labor costs. Automated assembly results in greater consistency and improved stability of the assembled screw press.

[0017] This device uses a stacking fixture to position the stacked sheaths, completing the positioning and stacking of the sheaths during the preceding cutting process, thus facilitating subsequent positioning and gripping. The preparation of the stacked sheaths requires no additional manpower, making it better suited for the assembly of this invention.

[0018] This device automates the gasket assembly by using a gasket dispensing device to dispense gaskets onto each mounting post, thereby improving the gasket installation efficiency and ultimately increasing the overall assembly efficiency of the stacked screw sheets. Attached Figure Description

[0029] Combined with appendix Figure 1-9 The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined in this application. Example 1:

[0030] The present invention discloses an automated assembly device for fixed and moving plates of a screw stacking machine, comprising a positioning frame 1, a first stacking seat 2, and a second stacking seat 3. The positioning frame 1 serves as the assembly position for the screw stacking plates, the first stacking seat 2 is used to place the stacked fixed plates, and the second stacking seat 3 is used to place the stacked moving plates. A lifting system 11 is installed on the positioning frame 1, and a corresponding positioning seat 12 is installed on the lifting system 11. The lifting system 11 drives the positioning seat 12 to rise and fall, thereby accommodating screw stacking plates of different heights. Specifically, the lifting system 11 includes a lifting slide rail 111 and a first lifting screw 112. The positioning seat 12 is provided with a sliding pair that cooperates with the lifting slide rail 111 and a screw nut. A first servo motor 113 is installed on the top of the positioning frame 1 to drive the first lifting screw 112 to rotate. Driven by the first servo motor 113, the first lifting screw 112 rotates, thereby causing the positioning seat 12 to rise and fall along the lifting slide rail 111 through cooperation with the screw nut.

[0031] The positioning base 12 has several positioning holes 13, which serve as insertion holes for the support column and are used for the installation and positioning of the mounting plate. A lifting cylinder 14 is installed below the positioning frame 1. A lifting mold 15 is installed at the front end of the piston rod of the lifting cylinder 14. The lifting mold 15 has contact heads 16 corresponding to the positioning holes 13. After assembly, the lifting cylinder 14 is used to lift the support column, and the contact heads 16 on the lifting mold 15 are used to lift the assembled stacked screw plate for hoisting. The positioning holes 13 are countersunk holes, and the diameter of the contact head 16 is the same as the small-diameter hole at the bottom of the positioning hole 13, ensuring stability after the mounting column is inserted. When ejecting the mounting column, the contact head 16 is inserted through the small-diameter hole at the bottom to push the bottom surface of the mounting column.

[0032] Both the first stacking base 2 and the second stacking base 3 are equipped with a stacking lifting mechanism 21 at their bottoms. Positioning grooves 22 are installed on the top surfaces of the first stacking base 2 and the second stacking base 3, and a stacking fixture 4 is placed within the positioning grooves 22. Specifically, the stacking fixture 4 includes a fixture base 41 and a pair of positioning cylinders 42. The fixture base 41 cooperates with the positioning grooves 22, which position the fixture base 41. The two positioning cylinders 42 are symmetrically arranged on the fixture base 41, and are used to position the inner holes of the stacked shear plates. The fixed and moving shear plates are both cut from sheet metal. The cut shear plates are stacked on the stacking fixture 4, and the positioning cylinders 42 position the two inner holes of the shear plates, thus serving as positioning components for subsequent shear plate gripping. Both the first stacking base 2 and the second stacking base 3 are provided with lifting channels 23. The stacking fixture 4 is provided with through holes corresponding to the lifting channels 23. The top of the stacking lifting mechanism 21 is equipped with a lifting head 24 that cooperates with the lifting channels 23. The lifting channels 23 are located below the stacked screw plates. The top of the lifting head 24 contacts the bottom of the stacked screw plates. Through the lifting action of the stacking lifting mechanism 21, the topmost stacked screw plate is disengaged from the positioning cylinder 42. In this embodiment, the lifting mechanism 21 includes a pair of lifting slide rails 211 and a lifting screw 212. The bottom of the lifting mechanism 21 has a fixed lifting sleeve and a fixed screw nut. The lifting slide rails 211 are slidably engaged with the lifting sleeve, and the lifting screw 212 is engaged with the screw nut. A lifting plate is mounted on the top of the lifting slide rail 211, and the lifting head 24 is mounted on the top surface of the lifting plate. A lifting servo motor 213 for driving the lifting screw 212 to rotate is mounted on the lifting plate. The motor shaft of the lifting servo motor 213 is connected to the lifting screw 212 via a coupling. The lifting screw 212 is rotatably connected to the bottom surface of the lifting plate. The lifting servo motor 213 drives the lifting screw 212 to rotate, thereby raising and lowering the lifting plate through the cooperation of the lifting screw 212 and the fixed screw nut, and the cooperation of the lifting slide rail 211 and the lifting sleeve. This allows the lifting head 24 to pass through the lifting channel 23 and abut against the stacked screw plate at the bottom. Through the stepping of the lifting mechanism 21, the topmost stacked screw plate can be lifted away from the position of the positioning cylinder 42 with each lift, thus facilitating subsequent gripping.

[0033] A lifting frame 5 is installed between the positioning frame 1 and the top of the first stacking seat 2 and the second stacking seat 3. The lifting frame 5 is fixed by a gantry structure or a top-mounted structure. A lifting rail 51 is installed at the bottom of the lifting frame 5, and the lifting rail 51 connects the positioning frame 1 with the first stacking seat 2 and the second stacking seat 3. Specifically, when arranging the equipment, the positioning frame 1, the first stacking seat 2, and the second stacking seat 3 are placed on the same straight line. This allows the gripping mechanism to perform linear displacement during the positioning, gripping, and assembly of the stacked screw plates, reducing equipment and control costs, shortening equipment formation time, and improving assembly efficiency.

[0034] A hoisting timing belt mechanism 52 is installed on one side of the hoisting track 51, and a clamping seat 6 is slidably installed on the hoisting track 51. A point on the timing belt of the hoisting timing belt mechanism 52 is fixedly installed to the clamping seat 6. Driven by the hoisting timing belt mechanism 52, the clamping seat 6 can be precisely displaced along the hoisting track 51, thereby moving above the first stacking seat 2 and the second stacking seat 3 to clamp the stacked screw pieces, and moving above the positioning frame 1 to assemble the stacked screw pieces, etc. A lifting mechanism 61 is installed at the bottom of the clamping seat 6, and two internal support claw chucks 62 are provided at the bottom of the lifting mechanism 61. The lifting mechanism 61 serves as a vertical action component for clamping and lowering the stacked screw pieces. Specifically, the lifting mechanism 61 includes a pair of fixedly installed lifting sleeves 63 and a fixed screw nut. A lifting slide rail 64 is slidably installed inside the lifting sleeves 63, and a second lifting screw 65 is fitted inside the fixed screw nut. A second servo motor 66 is installed on the connecting frame at the top of the second lifting screw 65, and the second servo motor 66 is used to drive the second lifting screw 65 to rotate. The bottom of the lifting slide rail 64 has a mounting plate 67, and the bottom of the second lifting screw 65 is rotatably connected to the mounting plate 67. The second servo motor 66 drives the second lifting screw 65 to rotate. With the cooperation of the second lifting screw 65 and the fixed screw nut, the lifting slide rail 64 is driven to slide up and down under the limit of the lifting sleeve 63, thereby completing the precise vertical displacement of the lifting mechanism 61. Two inner support claw chucks 62 are set at the bottom of the mounting plate 67. Through the precise lifting and lowering of the mounting plate 67, the inner support claw chucks 62 can accurately grip and assemble the stacked screw sheets. The inner support claw chucks 62 use their claws to position and grip the two inner holes of the stacked screw sheets, thereby achieving precise positioning and gripping of the stacked screw sheets, and completing the positioning and engagement of the stacked screw sheet mounting holes and support columns in subsequent assembly.

[0035] A pad dispensing device 7 is installed on one side of the positioning frame 1. The pad dispensing device 7 includes a dispensing frame 71, a transverse guide rail 72 and a transverse synchronous belt mechanism 73 on the dispensing frame 71, and a dispensing seat 74 slidably installed on the transverse guide rail 72. Driven by the transverse synchronous belt mechanism 73, the dispensing seat 74 can be displaced laterally under the limitation of the transverse guide rail 72. An extension sleeve 75 is fixedly installed on the dispensing seat 74, and an extension slide rail 76 is slidably installed on the extension sleeve 75. An extension synchronous belt mechanism 77 is installed on one side of the extension slide rail 76, and a point on the synchronous belt of the extension synchronous belt mechanism 77 is fixed to the dispensing seat 74. A dispenser 8 is provided at the front end of the extension slide rail 76. Through the movement of the extension synchronous belt mechanism 77, the extension slide rail 76 can be driven to make precise forward and backward displacement under the limitation of the extension sleeve 75. Driven by the transverse synchronous belt mechanism 73 and the extension synchronous belt mechanism 77, the dispenser 8 can be precisely displaced in the horizontal plane, allowing it to move above the mounting post and dispense the gasket accurately onto the post. The dispenser 8 has a dispensing channel 81, the height of which is slightly greater than the thickness of the gasket. A dispensing hole 82 is provided at the bottom front end of the dispensing channel 81, a pusher 83 is installed at the rear end, and a material cylinder 84 is installed at the top rear end. Specifically, the pusher 83 includes a push cylinder 85 and a push block 86. The push block 86 slides with the dispensing channel 81. When the push cylinder 85 is in the retracted state, the push block 86 is located behind the material cylinder 84. The gasket inside the material cylinder 84 falls into the dispensing channel 81 under gravity. The extension of the push cylinder 85, along with the push block 86, pushes the gasket to the dispensing hole 82, causing it to fall onto the mounting post. When the cylinder 85 retracts, the push block 86 moves to the rear side of the material cylinder 84, and the pad continues to fall into the feeding channel 81 under the action of gravity to wait for the next push.

[0036] Furthermore, in this embodiment, all moving elements are controlled by the controller.

[0037] According to the time sequence, the assembly procedure for the stationary and moving plates of the screw press using this device is as follows:

[0038] First, a forklift is used to place the stacking fixture 4 on the first stacking seat 2 and the second stacking seat 3. The fixed and moving plates are placed in the stacking fixture 4 on the first and second stacking seats 2 and 3 respectively. Then, the mounting post is inserted into the positioning hole 13 in the positioning seat 12. Next, the lifting mechanism 21, through the lifting head 24 and lifting channel 23, lifts the bottom of the stacked plates, causing the topmost fixed / moving plates to disengage from the positioning cylinder 42. Based on the assembly height, the height of the positioning seat 12 is adjusted by adjusting the lifting system 11 so that the dispenser 8 is slightly higher than the top of the mounting post. The controller controls the hoisting timing belt mechanism 52 to move the clamping seat 6 above the first stacking seat 2. Then, the lifting mechanism 61 lowers the inner support claw chuck 62 to clamp the fixed piece. Next, the lifting mechanism 61 raises the inner support claw chuck 62, and the hoisting timing belt mechanism 52 moves the clamping seat 6 directly above the positioning seat 12. The lifting mechanism 61 then lowers the inner support claw chuck 62 to insert the mounting hole on the fixed piece into the mounting column. Finally, the inner support claw chuck 62 releases the clamp, lowering the fixed piece. The lifting mechanism 61 then raises the inner support claw chuck 62, and the hoisting timing belt mechanism 52 moves the clamping seat 6 above the second stacking seat 3. Then, the lifting mechanism 61 lowers the inner support claw chuck 62 to clamp the moving piece. Finally, the lifting mechanism 61 raises the inner support claw chuck 62, and the hoisting timing belt mechanism 52 moves the clamping seat 6 directly above the positioning seat 12. Simultaneously, the controller controls the transverse synchronous belt mechanism 73 and the extension synchronous belt mechanism 77 to move the dispenser 8 above multiple mounting posts. The pusher 83 completes the dispensing and assembly of multiple washers. The dispenser 8 then resets, and the lifting mechanism 61 lowers the inner support claw chuck 62, placing the moving piece on top of the fixed piece. Multiple mounting posts limit the moving piece, preventing it from slipping. The assembly of the fixed piece, washers, and moving piece is then repeated until assembly is complete. After assembly, the lifting system 11 controls the positioning seat 12 to descend, and the lifting cylinder 14 lifts it. The contact head 16 pushes each mounting post out of the positioning hole 13, allowing the assembled stacked sheet to be hoisted away for later use. Example 2:

[0039] Regarding Embodiment 1, to compensate for misalignment errors during the gripping and assembly of the stacked screw sheets, this embodiment compensates for the displacement of the inner support claw chuck 62 in the lateral direction of the lifting track 51. Specifically, the gripping seat 6 includes a mounting seat 91 and a drive seat 92. The drive seat 92 cooperates with the lifting track 51. The lifting mechanism 61 is located at the bottom of the mounting seat 91. The bottom of the drive seat 92 is provided with a fine-tuning slide rail 93 and a fine-tuning screw 94. The top of the mounting seat 91 is provided with a fine-tuning sliding pair and a screw nut that cooperate with the fine-tuning slide rail 93. One end of the drive seat 92 is provided with a fine-tuning servo motor 95 for driving the fine-tuning screw 94. Driven by the fine-tuning servo motor 95, the mounting seat 91 can be finely adjusted laterally relative to the lifting track 51 by the cooperation of the fine-tuning screw 94 and the screw nut, thereby aligning the stacked screw sheets with the mounting column and lowering them down. Specifically, this fine-tuning process is completed manually by the operator. Example 3:

[0040] In Embodiment 1, the first stacking seat 2 and the second stacking seat 3 are positioned on opposite sides of the positioning frame 1. Two clamping seats 6 are installed on the hoisting rail 51. The lifting mechanism 61 and the inner support claw chuck 62 installed at the bottom of the clamping seats 6 are also in two sets. The two clamping seats 6 are located between the first stacking seat 2 and the positioning frame 1, and between the second stacking seat 3 and the positioning frame 1, respectively. Two hoisting synchronous belt mechanisms 52 are provided to cooperate with the clamping seats 6, and these mechanisms drive the clamping seats 6 on both sides respectively. Through the clamping and alternating assembly of the two sets of clamping mechanisms, assembly efficiency can be greatly improved. When assembling the fixed and moving pieces of the screw press, the clamping seats 6 on both sides move simultaneously. While assembling the moving pieces, the other clamping seat is completing the clamping of the fixed pieces, thereby shortening the material handling time and improving assembly efficiency.
