Description

Technical Field

[0001] The invention relates to a diaphragm folding mechanism, and in particular to a diaphragm folding mechanism and method. Background Art

[0002] In the current field of membrane folding technology, common operation processes include two main methods: one is to first transport the concentrated water net to the predetermined middle position of the membrane, then fix the membrane and the concentrated water net through the pressure plate, and use the membrane clamping claw to directly clamp the membrane from the other end and fold it. In this process, the pre-pressing plate will drop to press the folded membrane, and after the claws are withdrawn, the claw pressure plate will clamp the folded membrane and transport it away.

[0003] Another way is to transport the membrane to the designated location and place the concentrated water net vertically on a fixed position of the membrane, so that the membrane forms a certain arc when folded. Then, the clamping plate below will clamp the folded part, and the folded membrane will be turned down by the clamping plate and transported away in the horizontal direction.

[0004] However, both of these existing technologies have some obvious disadvantages. First, the structure of the folding mechanism is relatively complex, because it involves multiple independent mechanical parts and action steps, which leads to operational complexity. Secondly, due to the serial execution of multiple steps, the entire folding process takes a long time, which affects production efficiency. In addition, these complex actions and mechanisms also increase the difficulty of maintenance and the failure rate. Summary of the invention

The diaphragm pushing clamping cylinder is arranged and moves along the Y-axis direction, and the second clamp is connected to the diaphragm pushing clamping cylinder. The diaphragm sending folding cylinder is arranged and moves along the X-axis direction, and the lifting cylinder is arranged and moves along the Z-axis direction.

[0013] Furthermore, the end surface of the transverse pressure plate used to bypass the membrane and the concentrated water network is a curved surface.

[0014] Furthermore, the height of the pressing plate mechanism is lower than that of the lateral pressing plate.

[0015] A diaphragm folding method, the diaphragm folding method is: The clamping assembly of the displacement mechanism on the diaphragm clamps the diaphragm and moves the diaphragm along the X-axis direction through the sliding assembly; a part of the diaphragm is attached to the concentrated water net, and the displacement assembly of the displacement mechanism under the diaphragm controls the clamping claws to clamp the diaphragm attached with the concentrated water net, bypassing the transverse pressure plate of the pre-pressing mechanism and moving in the direction of the pressure plate mechanism.

DETAILED DESCRIPTION

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figure 1 and Figure 2 A diaphragm folding mechanism shown includes a diaphragm upper displacement mechanism, a pre-pressing mechanism, a diaphragm lower displacement mechanism and a pressing plate mechanism; The displacement mechanism on the diaphragm clamps and moves the diaphragm along the X-axis direction through a clamping assembly installed on the sliding assembly; the clamping assembly includes a clamping jaw 1 and a carrier plate 2, there are a plurality of clamping jaws 1 and they are evenly distributed on the carrier plate 2, the sliding assembly includes a slider 3 and a slideway 4, the carrier plate 2 is slidably arranged on a slideway 4 arranged in a horizontal direction through sliders 3 located at both ends, the clamping jaw 1 can push the diaphragm in the direction close to the pre-pressing mechanism along the X-axis direction, and the clamping jaw 1 continues to move forward to clamp a new diaphragm after releasing the diaphragm.

[0025] like Figure 3The displacement mechanism below the diaphragm shown includes a group of displacement components arranged symmetrically on both sides of the diaphragm, and the second clamp connected to the displacement component clamps and moves the diaphragm and the concentrated water net attached thereto along the X-axis, Y-axis and Z-axis directions; specifically, the displacement component of the displacement mechanism below the diaphragm includes a diaphragm-pushing clamp cylinder 5, a diaphragm-feeding folding cylinder 6 and a lifting cylinder 7 that are stacked and arranged in sequence from top to bottom, the diaphragm-pushing clamp cylinder 5 is arranged and moved along the Y-axis direction, the second clamp 8 is connected to the diaphragm-pushing clamp cylinder 5, the diaphragm-feeding folding cylinder 6 is arranged and moved along the X-axis direction, and the lifting cylinder 7 is arranged and moved along the Z-axis direction. Thus, the displacement component realizes the all-round displacement of the second clamp 8, which is conducive to flexibly clamping the diaphragm and moving the diaphragm and the concentrated water net obliquely downward to bypass the transverse pressure plate.

[0026] like Figure 4 The pre-stressing mechanism shown includes a transverse pressure plate, and a displacement mechanism under the diaphragm clamps and moves the diaphragm and the concentrated water net obliquely downward to bypass the transverse pressure plate to form a bending portion; the end surface of the transverse pressure plate 16 used to bypass the diaphragm and the concentrated water net is an arc surface, which plays a role in better guiding the diaphragm; at the same time, the pre-stressing mechanism also includes a crossbeam 9, a pre-stressing bar 10 and a pre-stressing bar cylinder 11, the crossbeam 9 is fixedly connected in the horizontal direction, the pre-stressing bar cylinder 11 is arranged on the crossbeam 9 along the Z-axis direction, and the pre-stressing bar 10 is connected to the pre-stressing bar cylinder 11 in the horizontal direction, driving the pre-stressing bar 10 to pre-stress from above the bending portion. It should be understood that after the pre-stressing mechanism pre-stresses the formed bending portion, the displacement assembly will control the jaws to move along the X-axis direction and the Y-axis to withdraw the jaws that clamp the diaphragm and the concentrated water net.

[0027] The pressure plate mechanism presses down the bending part through a pressure plate assembly that is movably arranged along the Z-axis direction. Specifically, the pressure plate assembly of the pressure plate mechanism includes a pressure plate cylinder 12 and a pressure plate 13. There are two pressure plate cylinders 12, and both are arranged along the Z-axis direction. The pressure plate cylinders 12 are arranged at both ends of the pressure plate 13. The pressure plate mechanism also includes a slider 14 and a slideway 15. There are two slideways 15 and they are arranged in the horizontal direction. There are two sliders 14 and they are slidably arranged on the slideway 15 one by one. The pressure plate cylinders 12 are connected to the sliders 14 one by one. The height position of the pressure plate mechanism is lower than the horizontal pressure plate 16. First, the pre-pressing mechanism clamps the lower displacement mechanism of the diaphragm and moves the diaphragm and the concentrated water network obliquely downward to bypass the bending part formed by the horizontal pressure plate, and then the pressure plate mechanism folds the bending part. The role of the slider 14 and the slideway 15 here is to translate the folded diaphragm backward and provide it to the subsequent processing steps.

[0028] At the same time, the present invention discloses a diaphragm folding method, specifically: the clamping assembly of the upper displacement mechanism of the diaphragm clamps the diaphragm and moves the diaphragm along the X-axis direction through the sliding assembly; a part of the diaphragm is attached to the concentrated water net, and the displacement assembly of the lower displacement mechanism of the diaphragm controls the clamping claw to clamp the diaphragm attached with the concentrated water net, bypassing the transverse pressure plate of the pre-pressing mechanism and moving in the direction of the pressure plate mechanism, such as Figure 5 As shown, the folding effect of the transverse pressure plate 16 during the movement causes the diaphragm to clamp the concentrated water network, the pre-pressing mechanism clamps the displacement mechanism below the diaphragm and moves the diaphragm and the concentrated water network obliquely downward to bypass the bending portion formed by the transverse pressure plate to perform pre-pressing, and the pressure plate mechanism folds the bending portion.

[0029] The diaphragm folding mechanism disclosed in the present invention comprises an upper diaphragm displacement mechanism, a pre-pressing mechanism, a lower diaphragm displacement mechanism and a pressure plate mechanism. Each mechanism works in coordination, reducing independent mechanical components and action steps, thereby simplifying the overall structure. All cylinders are integrated and stacked into a whole, and the structural design is more compact, which reduces redundant or difficult and time-consuming actions of folding the diaphragm. The folding process is efficient and flexible, and the operation complexity is effectively reduced. The diaphragm folding process will have fewer actions, faster time and higher efficiency throughout the process.

[0030] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the scope of the technical solution of the present invention also belong to the protection scope of the present invention.
