Description

Technical Field

[0001] The invention relates to a synthetic polyisoprene gasket siliconization technology, in particular to a synthetic polyisoprene gasket siliconization processing equipment. Background Art

[0002] Medicinal synthetic polyisoprene gaskets are commonly used as seals on infusion bags and infusion bottles. The processing of synthetic polyisoprene gaskets requires steps such as edge removal, acid and alkali treatment, cleaning, and siliconization.

[0003] For example, the publication (announcement) number is CN103254456B, and the publication (announcement) date is 2015-11-18, which discloses a method for producing a medicinal synthetic polyisoprene gasket, comprising the step of silicifying the synthetic polyisoprene gasket by immersing it in silicone oil.

[0004] The drawback of existing technologies is that the siliconization of gaskets on the market currently typically uses an immersion coating process, which requires a long siliconization time and reduces production efficiency. If a stirring device is used to improve the flow siliconization efficiency of silicone oil, the stirring rod will directly impact the gasket in contact with the silicone oil. As a result, the silicone oil on the gasket surface will be damaged and fall off due to mechanical stress, requiring more time to reattach, which has little effect on improving production efficiency. Alternatively, a pipeline can be installed to transport silicone oil tangentially along the silicone oil barrel, so that the silicone oil drives the gasket to rotate in a regular circle along the inner wall of the barrel, using centrifugal force to reduce center accumulation. However, there will be a situation where the gaskets on the outermost circle of the circumference directly impact the inner wall of the barrel, causing certain siliconization damage. Therefore, an elastic mesh metal basket is used to hold the gaskets. Accordingly, although the side wall of the basket reduces the stress caused by direct impact, it also blocks the silicone oil that enters the basket in the circumferential direction. Under the pulsed flow (the flow rate of the silicone oil is periodically adjusted to prevent the gasket from forming a fixed collision trajectory due to long-term uniform motion), the acceleration and deceleration of the gasket are uncontrollable. Especially when dealing with the simultaneous siliconization of a large number of gaskets, the probability of collision between gaskets is greatly increased, which correspondingly reduces the siliconization effect on the gasket surface. Summary of the Invention

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0021] See also Figure 1-12 The embodiment of the present invention provides a technical solution: a synthetic polyisoprene gasket siliconization processing equipment, including a siliconization barrel 1 and an electric push rod 2, and also includes: The inner container 3 has a plurality of liquid inlets 12 symmetrically arranged at the bottom and liquid outlets 13 symmetrically distributed on the side; A mesh basket 4 for holding gaskets is slidably mounted in the inner container 3, and a basket hole 40 is formed at the bottom of the mesh basket 4; The mesh panels 5 are symmetrically distributed in the mesh basket 4, and a channel 60 is formed between the two mesh panels 5; In the default state, the mesh plate 5 is in contact with the bottom of the mesh basket 4 and is driven to move horizontally and vertically, wherein: During horizontal movement, the plate holes 50 formed on the screen plate 5 are misaligned with the basket holes 40; During the vertical movement, a storage cavity 7 is formed between the mesh plate 5 and the bottom of the mesh basket 4 .

[0022] Specifically, a gantry or gate-shaped metal frame located on the ground is installed on the outside of the silicification barrel 1, and is used to install an electric push rod 2 with the output end facing downward. The end of the silicification barrel 1 can also be removably installed with a barrel cover 11. These are all existing technologies and will not be described in detail here.

[0023] Furthermore, the inner liner 3 (made of alloy metal, commonly used for storing silicone oil) is slidably installed on the siliconizing barrel 1 (the two are kept in alignment after installation (a sealing ring is required to be placed in the connecting gap between the two after the alignment), or the edge of the inner liner 3 port is fixed to the inner wall of the siliconizing barrel 1 by welding), and the liquid inlet 12 integrally formed at the bottom of the inner liner 3 is passed downward through the hole at the bottom of the siliconizing barrel 1, and then connected using a pipe with a threaded end. Similarly, the liquid outlet 13 is also connected using the same pipe, but the liquid outlet 13 uses a threaded interface to synchronously connect the inner liner 3 and the holes opened on the side of the siliconizing barrel 1 (the two holes need to be connected to thread the liquid outlet 13), so that the silicone oil transported upward is discharged through the side of the siliconizing barrel 1, and is used in conjunction with silicone oil circulation and transportation equipment (such as an infusion pump).

[0024] Furthermore, the liquid inlets 12 at the bottom of the inner container 3 are symmetrically distributed on both sides, and the multiple liquid inlets 12 on one side are arranged in an arc shape with equal distances, and the liquid inlet 12 is close to the side of the inner container 3. The purpose is to preferentially transport the silicone oil upward along the inner wall of the inner container 3 (such as Figure 4 As shown by the straight arrow in the middle, and the length of the straight arrow represents the flow rate of the silicone oil, so the silicone oil close to the inner wall of the inner liner 3 reaches the liquid surface first), then returns from the middle of the inner liner 3, and searches downward for the liquid outlet 13 for discharge (in the process, the downward silicone oil is greater than the silicone oil flow rate of the short arrow, so the silicone oil in the inner liner 3 presents two opposite, and maintains clockwise and counterclockwise flow states, and the downward arc arrow in the figure represents the silicone oil being discharged from the liquid outlet 13 (when facing one of the liquid outlets 13, the liquid inlet 12 is distributed on the left and right sides)), thereby causing the silicone oil in the basket 4 to present a regular up and down circulation flow.

[0025] Furthermore, the mesh basket 4 is specifically a stainless steel metal basket with multiple equal holes, and the mesh plate 5 is a stainless steel metal support plate with holes of the same size as the mesh basket 4. In the default state, the inner diameters of the basket holes 40 and the plate holes 50 coincide with each other. At this time, the flow rate of the silicone oil input into the mesh basket 4 is the lowest (adjusting the overlap of the holes of the two in combination with the flow rate of the liquid inlet 12 can make the adjustable range of the silicone oil flow rate in the mesh basket 4 larger, and the adjustment of the hole overlap area can directly act on the gasket, making the flow rate response more sensitive).

[0026] By pre-loading a large batch of gaskets into the mesh basket 4 and stacking them on the mesh plate 5, the mesh basket 4 is then lowered into the inner container 3 along with the electric push rod 2 (the upper end of the mesh basket 4 is always above the liquid level) and left to rest. This allows the upward-flowing silicone oil to circulate in opposite directions within the mesh basket 4, ensuring the regular rotation of the gaskets for siliconization and reducing mechanical stress. Directly feeding silicone oil upward through the basket holes 40 and plate holes 50 significantly reduces flow losses during pulsed flow and enables controllable acceleration and deceleration of the gaskets (controllable silicone oil delivery at the liquid inlet 12 is equivalent to flow rate control in the prior art). When the mesh plate 5 moves horizontally, reducing the overlap between the plate holes 50 and the basket holes 40, the flow rate of silicone oil entering the mesh basket 4 from the mesh plate 5 increases, providing greater flushing power for the large batch of gaskets. This allows the large batch to maintain regular rotation for siliconization, significantly reducing the probability of collision between gaskets, and thus enhancing the siliconization effect on the gasket surface. When the lower mesh plate 5 is moved vertically to make the channel 60 form the upper port of the storage chamber 7, the downward flowing silicone oil will send the gasket from the channel 60 into the storage chamber 7. At this time, the mesh plate 5 divides the mesh basket 4 into a double-layer siliconized space (the corresponding gasket is in the siliconization finishing work, the silicone oil flow rate is reduced, and the circulating flow and transportation are not working), which is used to limit the movement range of the gasket, slow down the gasket and reduce the rigid impact caused by mutual collision, thereby improving the efficiency of the gasket siliconization finishing work.

[0027] In another embodiment provided by the present invention, a connecting rod 21 connected to the output end of the electric push rod 2 is rotatably provided on the basket 4.

[0028] Specifically, a connector 22 is integrally formed at the lower end of the connecting rod 21, and the end of the connector 22 has a thread for connecting to a nut (after the nut reaches the maximum thread tightening stroke, the distance between the nut and the metal sheet integrally formed on the connector 22 is greater than the thickness of the bottom of the basket 4. The purpose is to allow the basket 4 to still rotate circumferentially after the basket 4 is clamped and installed (equivalent to the bolt and nut installation method).

[0029] By installing the net basket 4 at the end of the connecting rod 21, and then fixing the connecting rod 21 to the output end of the electric push rod 2 with bolts and nuts, the electric push rod 2 can push and pull the net basket 4 up and down, making it convenient to immerse the gasket in silicone oil, and at the same time, the net basket 4 can also be adjusted to a predetermined height.

[0030] In another embodiment provided by the present invention, the inner wall of the inner container 3 is symmetrically provided with a guide slope 31, and the guide slope 31 is divided into a high surface 312 and a lower inclined surface 313 according to its shape; The end of the screen plate 5 driven to move downward slides with the high surface 312 and the lower inclined surface 313 in sequence, so as to drive the screen plate 5 to move horizontally.

[0031] Specifically, a slider 51 is welded to the top of the arc of the mesh plate 5, and symmetrically arranged vertical limiting holes 41 are opened on the side wall of the mesh basket 4 so that the slider 51 can slide in the limiting holes 41, and the slider 51 extends out of the outer wall of the mesh basket 4 in the default state.

[0032] Furthermore, the guide slope 31 is integrally formed on the inner wall of the inner liner 3, and the end surface where the guide slope 31 and the slider 51 slide in contact has an arc-shaped depression concentric with the inner liner 3, so that the downward moving slider 51 limits the rotation of the basket 4.

[0033] Furthermore, Figure 4 As shown, the closer the lower inclined surface 313 is to the bottom of the inner container 3 , the larger the straight-line distance between the lower inclined surfaces 313 on both sides.

[0034] Furthermore, the inner wall of the bottom of the basket 4 is integrally formed with a plurality of protrusions 43 (the outer wall of the bottom of the basket 4 is extruded by the protrusions on the mold), and the mesh plate 5 is provided with a plurality of parallel strip holes 54, and the strip holes 54 are sleeved on the outside of the protrusions 43 for sliding contact.

[0035] During the downward movement of the screen plate 5, the slider 51 slides from the high surface 312 to the lower inclined surface 313, and the slope of the lower inclined surface 313 is used to move the two sliders 51 away from each other, thereby actively reducing the overlapping area between the plate hole 50 and the basket hole 40. During the process, the bar hole 54 slides along the ridge 43 to achieve guide limit, thereby ensuring stable translation of the screen plate 5.

[0036] In another embodiment provided by the present invention, an elastic member 6 is fixedly installed between the two mesh plates 5, and the elastic member 6 is slid down in sequence to restore the deformation.

[0037] Specifically, when the slider 51 contacts the lowest position of the lower slope 313, the elastic member 6 completely recovers its deformation (that is, the maximum stroke of the slider 51 radially away from the connecting rod 21 is to contact the inner wall of the inner tank 3). When the slider 51 is located on the end surface of the guide slope 31 and slides circumferentially, it needs to overcome the resistance of the elastic member 6 to continue to deform, so the slider 51 can stably move up and down.

[0038] Further, such as Figure 9As shown, the two ends of the elastic member 6 are welded to the flat ends of the two mesh plates 5, but the vertical lines formed by the welding positions (perpendicular to the flat ends of the mesh plates 5) are arranged in parallel (not overlapping). Therefore, after the elastic member 6 is compressed, the vertical line of the tangent line of the top of the bending arc and the radius line of the mesh basket 4 will be separated, and the deformation and bending ability of one end of the elastic member 6 (far from the axis of the mesh basket 4) is greater than the deformation and bending ability of the other end (close to the axis of the mesh basket 4). Therefore, when the elastic member 6 recovers its deformation, the end with greater deformation and bending ability actively generates a thrust in a specified direction (the component force in the thrust direction forms tangents on the two circles, so that the force has circumferential power). At the same time, the thrust is distributed circumferentially, which enables the two elastic members 6 to apply a torsional force to the mesh plates 5, so that the two mesh plates 5 have circumferential movement ability.

[0039] As the slider 51 slides along the lower inclined surface 313, the elastic member 6 recovers its deformation and pushes the two mesh panels 5 to slide along the guides of the protrusions 43, achieving horizontal movement of the mesh panels 5. When the slider 51 is at the elevated surface 312, the elastic member 6 undergoes its maximum compression deformation under operation (but below the elastic limit of the elastic member 6). Furthermore, the elastic member 6's maximum deformation under non-operational conditions allows the slider 51 to retract into the mesh basket 4, facilitating assembly and disassembly of the two mesh panels 5 from the mesh basket 4.

[0040] In another embodiment provided by the present invention, the mesh plate 5 abuts against a limiting protrusion 32 provided on the inner wall of the inner container 3, so that the mesh plate 5 moves to the end position.

[0041] Specifically, the limiting protrusion 32 is integrally formed on the lower inclined surface 313 , so when the slider 51 reaches the end position, it will be restricted and unable to move further downward. At this time, the elastic member 6 cannot restore its deformation, so the elastic member 6 still retains elastic force.

[0042] When the slider 51 moves down to the position of the limiting protrusion 32, it stops, and when the basket 4 is driven to continue to move downward, the mesh plate 5 is passively moved away from the bottom of the basket 4, thereby forming a storage cavity 7, which is convenient for the storage cavity 7 to be used for the completion of the siliconization work.

[0043] In another embodiment provided by the present invention, an opening 42 is opened on the side of the basket 4 to cooperate with the lower inclined surface 313 for drainage.

[0044] Specifically, the opening 42 is symmetrically arranged and is arranged on the same side as the guide slope 31 so that the opening 42 and the lower inclined surface 313 are connected.

[0045] By maintaining contact with the basket 4 as it moves downward to the high surface 312, the opening 42 is sealed by the high surface 312. (Although the inner wall of the inner liner 3, which does not have a guide slope 31, does have an arc-shaped chamber outside the basket 4, this arc-shaped chamber lacks a liquid inlet 12. Therefore, the silicone oil does not flow rapidly upward along the arc-shaped chamber into the side wall of the basket 4. Instead, it flows in a gentle manner, causing minimal interference with the circulation flow within the basket 4 and is negligible here.) When the opening 42 reaches the lower slope 313, the opening 42 becomes exposed, and the silicone oil delivered upward from the liquid inlet 12 flows along the slope of the lower slope 313 and enters through the opening 42. This portion of silicone oil flowing into the basket 4 is directed in the same direction as the upward path of the circulation flow, thereby assisting the circulation flow, making the circulation flow more stable, and thus ensuring the regular rotation and siliconization of the gasket. The electric push rod 2 can adjust the downward position of the opening 42 according to actual needs, thereby adjusting the amount of silicone oil delivered to the opening 42 by the lower slope 313.

[0046] In another embodiment provided by the present invention, a limiting groove 33 is provided on the limiting protrusion 32 , and the elastic member 6 under reset drives the screen plate 5 to slide back and forth with the limiting groove 33 .

[0047] Specifically, the limiting groove 33 is an arc-shaped depression on a horizontal plane, so as to allow the slider 51 to stay at the bottom of the depression.

[0048] By suddenly lowering the basket 4 (having reached the slope position of the lower slope 313, and the opening 42 has been operated and has begun to finish the work) until the slider 51 suddenly contacts the limiting groove 33, the elastic member 6 suddenly releases the torque to make the two mesh plates 5 rotate circumferentially (the bar holes 54 and the protrusions 43 are separated from each other), thereby making the slider 51 climb from the bottom of the arc-shaped depression to one side. However, after climbing, the elastic member 6 will be pressed again. Therefore, during the process of the elastic member 6 recovering its deformation, the slider 51 will pass through the arc-shaped depression. The bottom of the channel 60 is moved upwards and downwards, and the sliding block 51 is moved back and forth until the sliding block 51 stops at the bottom of the arc-shaped depression, thereby realizing the reciprocating circumferential rotation of the screen plate 5, so that the channel 60 can continuously switch positions, and the screen plate 5 can also sieve and comb the gaskets accumulated above it, making the gaskets looser and facilitating the flow of silicone oil to transport the gaskets downwards, and then sending the gaskets floating at the end of the channel 60 into the storage chamber 7, so that the storage chamber 7 can collect and store all the gaskets in advance.

[0049] In another embodiment provided by the present invention, an elastic strip 52 is provided at the end of the mesh plate 5 and is deformed by abutting against the inner wall of the opening 42 .

[0050] Specifically, the arc-shaped elastic strip 52 is welded to the end surface of the slider 51, and the end of the elastic strip 52 is integrally formed with an elastic edge 53 (both made of elastic metal sheets). The elastic strip 52 in the default state is embedded in the limiting hole 41 (such as Figure 5 As shown in FIG, the elastic edge 53 serves to prevent the elastic strip 52 from sliding out of the limiting hole 41 toward the outside of the basket 4, so that the elastic strip 52 maintains stable operation.

[0051] Furthermore, the elastic potential energy of the elastic strip 52 is smaller than the elastic potential energy of the elastic member 6 , the limiting hole 41 and the opening 42 are connected, and the connecting position is rounded to facilitate the sliding block 51 to slide into the opening 42 .

[0052] When the slider 51 stops and slides in the limiting hole 41, the two elastic strips 52 are compressed and deformed and slide against the inner wall of the upper end of the opening 42, so that the elastic strips 52 can be reset to push the mesh 5 back to the default state. After the mesh 5 moves vertically, the slider 51 enters the opening 42 from the limiting hole 41, so that the opening 42 provides the slider 51 with circumferential movement space. Since the elastic strip 52 is in the middle of the opening 42 in the default state, it uses its own width to intercept the silicone oil flowing through the opening 42, and after interception, the silicone oil is divided into two auxiliary flows of equal flow rate. When the elastic strip 52 moves circumferentially, the two auxiliary flows repeatedly switch flow rates, which can make it easier to disperse the gaskets accumulated on the top of the mesh 5, and facilitate the gaskets to enter the storage cavity 7. At this time, the basket 4 loses the connection between the slider 51 and the limiting hole 41, so that the basket 4 will also move circumferentially on the connecting rod 21 (the basket 4 loses the limitation of the guide slope 31, and under the action of uneven distribution of internal gaskets and different liquid impact forces, the basket 4 is impacted by the upwardly transported silicone oil and moves circumferentially at will), thereby enabling the movable basket 4 to sieve and sort out the gaskets in the storage chamber 7, making the gaskets in the finishing work more dispersed, reducing the accumulation of gaskets in the storage chamber 7, and also reducing the blockage of gaskets at the end of the channel 60.

[0053] In another embodiment provided by the present invention, an upper inclined surface 311 is provided on the high surface 312 , and the mesh plate 5 repeatedly slides with the upper inclined surface 311 to make the spacing between the channels 60 adjustable.

[0054] Specifically, the upper slope 311 and the lower slope 313 are symmetrical, and the slope angles and lengths of the two slopes are the same. The bottom of the upper slope 311 coincides with the port of the inner liner 3, so when the slider 51 enters the inner liner 3 downward, it slides directly on the guide slope 31.

[0055] After the siliconization is completed, the basket 4 is pulled up to the upper inclined surface 311 and away from the liquid surface to drain the silicone oil. At this time, the elastic member 6 is in a state of recovery deformation, and the electric push rod 2 is used to repeatedly push and pull the basket 4 up and down to separate the residual silicone oil under the action of inertia. At the same time, the mesh plate 5 is repeatedly moved horizontally to comb out the remaining gaskets on it, and the channel 60 is opened to the maximum spacing to enhance the ability of the gaskets to enter the storage chamber 7. Manual labor is also required to feed the remaining gaskets, so that the gaskets can obtain a safe and stable anti-spill space in the storage chamber 7, and have a high-efficiency drainage function.

[0056] In another embodiment provided by the present invention, the deformed elastic strip 52 causes the mesh plate 5 to move toward the mesh basket 4 to compact the gasket in the storage chamber 7 .

[0057] After all the gaskets are delivered to the storage chamber 7, the accumulated gaskets force the mesh plate 5 to maintain a predetermined distance from the bottom of the mesh basket 4. The elastic strips 52 are then deformed by pressure, and the elastic reaction force causes the mesh plate 5 to apply pressure to the gaskets, thereby facilitating the drainage of residual silicone oil. Simultaneously, the mesh basket 4 is completely separated from the inner liner 3 (still within the siliconized barrel 1). At this point, the slider 51 is free from the arc-shaped depression of the guide slope 31, and the mesh basket 4 is manually rotated, utilizing centrifugal force to accelerate the removal of residual silicone oil. At this point, the slider 51 is freely movable within the opening 42, and the mesh basket 4 is rotated forward and backward. This causes the mesh plate 5, under circumferential inertia, to impact the sidewalls of the opening 42 using the slider 51, generating vibrations in the mesh basket 4 and further enhancing the silicone oil drainage effect.

[0058] Working principle: By placing a large number of gaskets into the mesh basket 4 in advance and stacking the gaskets on the mesh plate 5, the mesh basket 4 is then lowered into the inner tank 3 along with the electric push rod 2 and left to stand, so that the upward-flowing silicone oil forms a reverse circulation flow in the mesh basket 4, satisfying the siliconization treatment of the regular rotation of the gaskets and reducing mechanical stress. The silicone oil is directly transported upward through the basket holes 40 and the plate holes 50, which can greatly reduce the flow loss of silicone oil under pulsed flow and make the acceleration and deceleration of the gaskets controllable. When the mesh plate 5 moves horizontally to reduce the overlapping area between the plate holes 50 and the basket holes 40, the flow rate of the silicone oil entering the mesh basket 4 from the mesh plate 5 increases, which can provide greater flushing ability for large quantities of gaskets and satisfy the regular rotation siliconization of large quantities of gaskets. When the lower mesh plate 5 is moved vertically to make the channel 60 form the upper port of the storage chamber 7, the downward flowing silicone oil will send the gasket from the channel 60 into the storage chamber 7. At this time, the mesh plate 5 divides the mesh basket 4 into a double-layer siliconized space to limit the movement range of the gasket, slow down the gasket and reduce the rigid impact caused by mutual collision.

[0059] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
