Description

Technical Field

[0001] The present invention relates to the technical field of liquid chromatographs, and in particular to a continuous processing device for advanced liquid chromatograph components and a working method thereof. Background Art

[0002] In advanced liquid chromatography, as the plunger seal wears, small particles can fall through the pipeline and enter the sample injection valve, damaging the valve and potentially contaminating the chromatographic column. Therefore, a liquid chromatography in-line filter is installed between the pump outlet and the injection valve. Its cup-shaped structure provides a large liquid-receiving area and a long service life, effectively preventing particles from entering the system while ensuring adequate liquid flow. The sieve plate in the in-line filter plays a crucial role, intercepting impurities in the mobile phase and protecting the liquid phase system.

[0003] In the production process of stainless steel sieve plates, it is usually necessary to use blanking equipment for continuous blanking production. For example, the existing patent publication number CN112475004A discloses a stainless steel sieve plate manufacturing process, including a base plate, a blanking device, a clamping device, a lifting device and a cleaning module. The blanking device is fixedly installed on the base plate, and the lifting device is fixedly installed on the base plate. The lifting devices are symmetrically arranged on both sides of the blanking device, and a clamping device is provided on the blanking device.

[0004] In the above technical solution, the punching die is fixed by a clamping device, the punching die is controlled to move intermittently by a lifting device, and the punching head is controlled by the punching device to punch the stainless steel sieve plate to be punched. However, burrs and burrs are inevitably present on the outer edges of the sieve plate after punching, which will greatly affect the subsequent normal use and require further polishing process for processing.

[0005] Therefore, it is necessary to provide a continuous processing device for advanced liquid chromatography components and a working method thereof, which can achieve the effect of automatic chamfering. Summary of the Invention

[0040] See also Figure 1-9 The present invention provides a technical solution: a continuous processing device for advanced liquid chromatography components and a working method thereof, comprising a collecting box 5, a punching component, a grinding component, a discharge component and a transfer table 2,

[0041] At least one set of punching dies is eccentrically arranged on the inner side of the turntable 2. The turntable 2 drives the punching dies to rotate sequentially and cyclically between the punching assembly, the grinding assembly and the unloading assembly.

[0042] The punching assembly includes a cylinder assembly 9 and a punching punch 901. When the punching punch 901 corresponds to the punching die, the cylinder assembly 9 drives the punching punch 901 to punch out the sieve plate body 6 from the strip plate 601. The sieve plate body 6 falls into the punching die. A limiting assembly is provided in the punching die to support and limit the sieve plate body 6. The grinding assembly grinds burrs on the sieve plate body 6. The unloading assembly pushes the sieve plate body 6 out of the punching die and drops it into the collection box 5.

[0043] A supporting top plate 8 is provided on the upper side of the turntable 2, the lower end of the supporting top plate 8 is fixedly connected to a supporting column 801, the lower end of the supporting column 801 is fixedly connected to a bottom plate 802, the middle end of the supporting column 801 is fixedly connected to the support platform 1, the turntable 2 is rotatably connected to the middle side of the support platform 1, and a loading belt 7 and a feeding belt 701 are provided at both ends of the support platform 1. The loading belt 7 is used to transfer the strip plate 601 to the support platform 1.

[0044] First, the strip plate 601 to be punched is transported to the upper side of the transfer table 2 through the feeding belt 7. When the punching punch 901 corresponds to the position of the punching die, the punching punch 901 is driven down by the cylinder assembly 9 to cooperate with the punching die to punch the strip plate 601. The punching punch 901 punches out the sieve plate body 6 and presses it into the punching die; the limiting assembly inside the punching die supports and limits the sieve plate body 6, and drives it to move to the grinding assembly position through the rotation of the transfer table 2. At the same time, , the feeding belt 7 continues to transport the strip plate 601 to the lower side of the blanking punch 901 for the next blanking; then the grinding component grinds the outer edge of the sieve plate body 6 to remove burrs and ensure the surface quality of the product; then the turntable 2 drives the polished sieve plate body 6 to move to the unloading component position, and the unloading component unloads the sieve plate body 6 into the collection box 5, thus completing the continuous blanking and grinding integrated work of the sieve plate body 6, greatly improving efficiency and high degree of automation;

[0045] Preferably, three sets of blanking dies are provided, corresponding to the blanking punch 901, the grinding assembly and the unloading assembly respectively, so that while the blanking punch 901 is performing the blanking work, the grinding assembly and the unloading assembly are simultaneously performing the grinding and unloading work on the screen plate body 6, further improving the work efficiency, and cooperating with the intermittent rotation of the turntable 2, thereby realizing continuous production and processing operations.

[0046] The punching die includes a die cylinder 101, which passes through the turntable 2 and is fixedly connected thereto. The inner diameter of the die cylinder 101 is adapted to the punching punch 901. The limit assembly includes a plurality of upper limit mechanisms and a plurality of lower limit mechanisms. The upper limit mechanism includes an arc-shaped grinding block 102. The inner side of the arc-shaped grinding block 102 is provided with a downward arc-shaped inclined surface, which is adapted to the outer edge of the screen plate body 6. In the initial state, the arc-shaped grinding block 102 extends to the inner side of the die cylinder 101, and the die The cylinder 101 is penetrated by a number of square through holes, and a removable cover plate 103 is provided on the outside of the square through holes. A fixed grinding block 104 is fixedly connected to the square through holes. One side of the fixed grinding block 104 is provided with an inclined surface adapted to the arc-shaped grinding block 102, and the inner side of the fixed grinding block 104 is provided with an arc surface with the same inner diameter as the die cylinder 101. The setting directions of the upper limit mechanisms and the lower limit mechanisms are opposite to each other and are arranged in a ring-shaped staggered manner. The upper limit mechanism and the lower limit mechanism limit the screen plate body 6 between the two.

[0047] Preferably, the limiting assembly is provided with several upper limiting mechanisms and several lower limiting mechanisms. Specifically, in the initial state, the arc-shaped grinding block 102 extends to the inner side of the die cylinder 101, and the arc-shaped grinding blocks 102 arranged oppositely up and down limit the sieve plate body 6 in the middle (such as Figure 4 shown);

[0048] Specifically, when the punching punch 901 is punching, the punched out sieve plate body 6 is pressed into the die cylinder 101. At this time, the sieve plate body 6 contacts the upper arc-shaped grinding block 102 and presses it down. The arc-shaped grinding block 102 moves along the inclined surface of the fixed grinding block 104, so that the arc-shaped grinding block 102 moves into the square through hole, so that the sieve plate body 6 falls on the arc-shaped inclined surface of the lower arc-shaped grinding block 102. Then the punching punch 901 rises and resets, so that the upper arc-shaped grinding block 102 also re-extends into the die cylinder 101, so that the sieve plate body 6 is restricted in the middle by the upper and lower arc-shaped grinding blocks 102, and the right angle of its outer edge contacts the arc-shaped inclined surface, and the outer edge end face contacts the inner arc surface of the fixed grinding block 104.

[0049] The grinding assembly includes an electric telescopic rod 107 and a lifting rotary disk 109. The lower end of the electric telescopic rod 107 is rotatably connected to the pressing disk 108. The electric telescopic rod 107 is arranged at the lower end of the supporting top plate 8. The lifting rotary disk 109 is arranged on the upper side of the bottom plate 802 and is correspondingly arranged below the pressing disk 108. The pressing disk 108 and the lifting rotary disk 109 are relatively displaced to clamp the screen plate body 6 and rotate it.

[0050] Preferably, the grinding surface of the arc-shaped grinding block 102 is set to be an arc-shaped inclined surface, and the grinding surface of the fixed grinding block 104 is an inner arc surface, and the upper and lower right-angle ends of the outer edge of the sieve plate body 6 are in contact with the arc-shaped inclined surface of the arc-shaped grinding block 102, and the outer edge end face is in contact with the inner arc surface of the fixed grinding block 104, so that the edges of the sieve plate body 6 that are punched are in contact with the grinding surface. When grinding work is required, the pressing plate 108 is pushed down by the electric telescopic rod 107, and the lifting rotary plate 109 is raised, so that the sieve plate body 6 in the die cylinder 101 is clamped in the middle, and then the lifting rotary plate 109 is rotated to drive the sieve plate body 6 to rotate itself, and continuously grind between it and the static grinding surface to remove burrs, thereby ensuring the surface quality of the product.

[0051] A pair of trapezoidal slide grooves are provided at the upper end of the square through hole, and a trapezoidal slider 105 is slidably fitted on the inner side of the trapezoidal slide groove. A spring telescopic rod 106 is provided at one end of the trapezoidal slider 105, and the spring telescopic rod 106 is connected to the cover plate 103. A spring retraction rod is provided at the lower end of the trapezoidal slider 105, and the spring retraction rod is connected to the arc-shaped grinding block 102.

[0052] Preferably, a spring telescopic rod 106 and a trapezoidal slider 105 are provided for guidance, and a spring retraction rod is provided between the trapezoidal slider 105 and the arc-shaped grinding block 102, so that the arc-shaped grinding block 102 is in contact with the trapezoidal slider 105 in the initial state. Specifically, when the sieve plate body 6 is punched into the die cylinder 101, the sieve plate body 6 is pressed on the upper end of the upper arc-shaped grinding block 102. Under the guidance of the spring retraction rod, the arc-shaped grinding block 102 moves downward in a straight line, and the arc-shaped grinding block 102 is displaced along the inclined surface of the fixed grinding block 104, thereby being retracted into the square through hole. The trapezoidal slider 105 is horizontally displaced for guidance, thereby ensuring the stability of the overall oblique displacement of the arc-shaped grinding block 102.

[0053] The unloading assembly includes a unloading plate 501 , the upper end of which is provided with an electric telescopic rod 2 502 , and the collecting box 5 is provided at the upper end of the bottom plate 802 and corresponds to the position of the unloading plate 501 .

[0054] When unloading is required, the unloading plate 501 is pushed down by the electric telescopic rod 502, and the unloading plate 501 pushes the sieve plate body 6 to move downward, and the sieve plate body 6 slides along the arc-shaped inclined surface of the lower arc-shaped grinding block 102, thereby pushing the arc-shaped grinding block 102 back into the square through hole, so that the sieve plate body 6 can be unloaded into the collection box 5, and the unloading is completed. That is to say, through the setting of the arc-shaped grinding block 102 and the fixed grinding block 104, the sieve plate body 6 can pass through the restriction of the front or back arc-shaped grinding block 102 under the action of thrust, with a high degree of automation and strong practicality.

[0055] The upper end of the base plate 802 is fixedly connected to a center column 201, which passes through the turntable 2 and is rotatably connected thereto. The inner side of the center column 201 is fixedly connected to a motor component 202, and the upper side of the motor component 202 drives a gear 1 203, and one side of the gear 1 203 is meshed with an inner gear ring 204, which is fixedly connected to the turntable 2. An annular groove for the inner gear ring 204 to rotate is provided on the outer side of the center column 201.

[0056] Preferably, when the turntable 2 needs to be driven to rotate intermittently, the motor 202 drives the gear 1 203 to rotate, and the gear 1 203 engages with the inner gear ring 204 to drive the inner gear ring 204 and the turntable 2 to rotate.

[0057] A pair of driving wheels 209 are provided at the upper end of the center column 201, and the lower end of the supporting top plate 8 is fixedly connected to the connecting column 4. The lower end of the connecting column 4 is fixedly connected to a pair of pressing wheels 401. The pressing wheels 401 press the strip plate 601 against the driving wheel 209. The driving wheel 209 is used to drive the intermittent feeding of the strip plate 601.

[0058] Preferably, the driving wheel 209 is rotated to drive the strip plate 601 to feed, and in order to improve the feeding stability, a pair of pressing wheels 401 are provided, corresponding to the driving wheel 209, so that the strip plate 601 is pressed against the driving wheel 209, and the two are kept in close fit, thereby ensuring the feeding accuracy and stability.

[0059] The lower end of gear 1 203 is fixedly connected to bevel gear 1 205, one side of bevel gear 1 205 is meshedly connected to bevel gear 2 206, one end of bevel gear 2 206 is fixedly connected to gear 2 207, the upper side of gear 2 207 is meshedly connected to gear 3 208, the middle side of gear 3 208 passes through and is fixedly connected to a rotating rod, which passes through a pair of driving wheels 209 and is fixedly connected thereto.

[0060] Preferably, the motor component 202 drives gear 1 203 to rotate while also driving bevel gear 1 205 to rotate, and drives bevel gear 2 206 and gear 2 207 to rotate through meshing connection, and gear 2 207 drives gear 3 208 and the rotating rod to rotate, which can drive a pair of driving wheels 209 to rotate and drive the strip plate 601 to feed. That is to say, when the turntable 2 drives the die cylinder 101 to rotate and switch positions, it synchronously drives the strip plate 601 to feed. The two have good synchronization and high degree of automation, so that each time the empty die cylinder 101 moves to the lower side of the punching punch 901, the strip plate 601 is automatically fed, and the punching punch 901 can directly start the punching work, thereby improving efficiency.

[0061] The grinding assembly also includes a base 110, and a cylinder part 111 is provided on the inner side of the base 110. The driving end of the cylinder part 111 is rotatably connected to a torsion bar 112. Straight key slots are provided at both ends of the torsion bar 112.

The gear five is driven to rotate by the motor assembly, and the torsion bar 112 is fixedly connected to the lifting rotary disk 109.

[0062] Preferably, when it is necessary to drive the lifting rotary disk 109 to lift and rotate, the motor assembly drives gear five to rotate, driving gear four 114 to rotate, and the driving key 113 transmits torque to drive the torsion bar 112 to rotate, which can drive the lifting rotary disk 109 to rotate, and the cylinder part 111 drives the torsion bar 112 to move, which can drive the lifting rotary disk 109 to lift, and the driving key 113 slides in the straight key slot, which will not affect the normal rotation of the lifting rotary disk 109.
