Description

Technical Field

[0001] The present invention relates to the technical field of rubber stopper production equipment, and in particular to a drying device for rubber stopper production. Background Art

[0002] A rubber stopper is a sealing device made of rubber. It offers advantages such as dustproofing, waterproofing, wear resistance, tear resistance, aging resistance, oil resistance, and ozone resistance. It can be used to seal chemical or medical containers. After the rubber stopper is formed, some impurities such as dust and oil film may remain on its surface. These impurities must be cleaned and dried before packaging the finished product.

[0003] A Chinese patent document with publication number CN218210421U discloses a drying device for the production of medical rubber stoppers, which includes four sets of legs, a support platform, a drying device body, a heat dissipation pipe, a drying box, a feed pipe, a drying screen, a connecting rod, a rotating wheel, a support plate, a rotating shaft and a servo motor. A working chamber is provided in the drying box, a slide is provided in the middle of the outer wall of the working chamber, and multiple sets of heat dissipation holes are provided on the heat dissipation pipe; the drying screen is located in the working chamber, and batches of rubber stoppers are placed in the drying screen, and the drying screen swings up and down to shake off water droplets on the surface of the medical rubber stoppers, thereby improving the drying efficiency and effect of the medical rubber stoppers.

[0004] In the above scheme, the operation mode of the drying screen is to move vertically up and down periodically, and batches of rubber plugs are stacked in the drying screen. When the stacking density of the rubber plugs in the drying screen is large, the rubber plugs in the middle are least likely to be exposed to the drying airflow. Moreover, since the rubber plugs themselves have high elasticity, during the up and down vibration of the drying screen, the vibration effect on the rubber plugs in the middle is weaker, and the moisture on it is not easy to separate. The moisture here is the most difficult to flow out, that is, the drying efficiency of the rubber plugs in the middle of the drying screen is low. Summary of the Invention

[0005] The present invention provides a drying device for rubber stopper production, aiming to solve the problem of low drying efficiency of the middle rubber stopper in a drying screen in the related art.

[0006] The present invention relates to a drying device for rubber stopper production, comprising a machine body, a vibrating mechanism and a vibrating screen for holding rubber stoppers, wherein the machine body is connected to a hot drying pipe, the hot drying pipe is used to convey airflow into a drying chamber, the vibrating mechanism is used to control the vibrating screen to perform periodic motion within the machine body, a central axis column is coaxially connected to the middle of the vibrating screen, a hot drying channel is provided in the central axis column, the central axis column and the bottom plate are relatively fixed, a plurality of hot drying holes connected to the hot drying channel are provided on the side wall of the central axis column, the hot drying channel and the hot drying pipe are connected; the vibrating screen comprises a bottom plate, a top plate and a plurality of connecting columns, The two ends of the connecting column are respectively connected to the top plate and the bottom plate, and the connecting column undergoes elastic deformation along the movement direction of the vibrating screen; the central axis column is coaxially connected to the adjustment frame, and a plurality of extension bodies are fixedly connected to the adjustment frame, and the extension body extends radially along the central axis column. The adjustment frame includes a plurality of adjustment ribs, and the extension trajectory of the adjustment ribs is a spiral line around the axis of the central axis column. An adjustment groove for the adjustment ribs to pass through is provided on the top plate, and an auxiliary channel is provided in the extension body, and the auxiliary channel is connected to the hot drying channel. A plurality of air flow holes connected to the auxiliary channel are provided on the extension body.

[0007] The effect is that part of the hot drying air flow can enter the auxiliary channel and eventually flow out from the air flow hole and contact the rubber plug, thereby increasing the spatial position points and direction diversity of the hot drying air flow entering the vibrating screen and improving the drying efficiency.

[0008] The effect is as follows: the vibrating screen is filled with piles of rubber plugs to be dried. Driven by the vibration mechanism, the vibrating screen moves back and forth to shake the rubber plugs inside, making it easier to remove moisture from the rubber plugs. The central column and the vibrating screen are coaxial, that is, the central column is located in the middle of the vibrating screen, where the rubber plugs are piled up to the maximum. The hot drying pipe transports hot air to the central column, and the hot air eventually enters the vibrating screen through the hot drying holes, auxiliary channels or air flow holes and contacts the rubber plugs. The overall direction of the hot air flow is from the middle of the vibrating screen to the outside of the vibrating screen, so that the place with the highest docking density of rubber plugs in the vibrating screen is affected by the hot drying air flow the most, and the vibration During the vibration of the screen, the gaps between the rubber stoppers also change irregularly, and the hot drying gas passing through is more likely to contact various positions on the surface of each rubber stopper, thereby improving the overall drying efficiency of the rubber stoppers in the vibrating screen; when the top plate moves axially away from the bottom plate, the internal space of the vibrating screen becomes larger, and the groove wall and the adjusting ribs of the adjusting groove produce abutment force. Since the adjusting ribs are relatively inclined, the adjusting frame is subjected to a thrust perpendicular to the axis of the central column, so the adjusting frame rotates, and the extension body also rotates accordingly. On the one hand, it has a plucking effect on the rubber stoppers, and on the other hand, it also increases the position diversity of the air flow holes, further improving the heat drying effect.

[0009] Preferably, the length direction of the connecting column is parallel to the moving direction of the vibrating screen, and the connecting column includes a fixed cylinder and a movable column. One end of the fixed cylinder is fixedly connected to the bottom plate, one end of the movable column is connected to the top plate, and the other end of the movable column is coaxially inserted into the fixed cylinder. A movable spring is fixedly connected between the movable column and the fixed cylinder.

[0010] The effect is that the elastic connection between the fixed cylinder and the movable column allows the relative distance between the top plate and the bottom plate to change elastically. During the reciprocating movement of the vibrating screen, due to the effect of inertia, the top plate continuously moves closer to and away from the bottom plate, and the size of the internal space of the vibrating screen continuously changes. The degree of shaking and mutual collision of the rubber plugs inside is higher, which is more conducive to the separation of moisture.

[0011] Preferably, the vibrating screen further comprises a mounting ring plate, the mounting ring plate is coaxial with the bottom plate, the mounting ring plate is fixedly connected to all movable columns at the same time, and the top plate and the mounting ring plate are detachably connected by bolts.

[0012] The effect is that the top plate is detachably connected through the mounting ring plate and the connecting column, and after the top plate is removed, the top of the vibrating screen is open, which is convenient for placing the rubber plug therein.

[0013] Preferably, the vibration mechanism includes a connecting seat, the connecting seat is slidably connected to the machine body, the sliding direction is vertical, the connecting seat is connected to the vibrating screen, the central axis column and the base plate are coaxially rotatably connected, one end of the central axis column passes through the base plate and is fixedly connected to a connecting threaded cylinder, a threaded column is fixedly connected to the connecting seat, the connecting threaded cylinder and the threaded column are coaxially threadedly connected, and the side of the base plate facing away from the top plate abuts against the connecting seat.

[0014] Preferably, a plurality of positioning pins are fixedly connected to the side of the connecting seat facing the base plate, and a positioning hole is opened on the base plate for the positioning pins to pass through. The axes of the positioning pins and the positioning holes are parallel to the axis of the central axis column, and the axial length of the positioning pins is greater than the axial length of the threaded column.

[0015] The effect is that: during the installation of the vibrating screen and the connecting seat, when the positioning pins and the positioning holes are aligned one by one, the connecting threaded cylinder and the threaded column are also coaxially aligned, and then the vibrating screen continues to descend and the central axis column is rotated, the connecting threaded cylinder and the threaded column are threadedly connected, and when the side of the bottom plate facing away from the top plate abuts against the connecting seat, the connecting seat and the vibrating screen are relatively fixed.

[0016] Preferably, the adjustment frame also includes a stabilizing rib, the number of the stabilizing ribs is consistent with the adjustment ribs and the two are connected one-to-one, the length direction of the stabilizing ribs is parallel to the length direction of the central axis column, the stabilizing ribs are located at the end of the adjustment rib facing the base plate, and the adjustment groove is also for the stabilizing rib to pass through. In a natural state, the stabilizing ribs are located in the adjustment groove.

[0017] The effect is that when the top plate moves closer to the bottom plate, the internal space of the vibrating screen becomes smaller, and the top plate may squeeze or collide with the rubber plug, and the stacking density of the rubber plug is also higher. At this time, since the length direction of the stabilizing rib is parallel to the moving direction of the top plate, the adjustment frame does not rotate and the extension body does not rotate, so as to reduce the extrusion force between the extension body and the rubber plug.

[0018] Preferably, the extension body includes an extension tube and an extension ball, one end of the extension tube is fixedly connected to the adjustment frame, and the other end is fixedly connected to the extension ball, the auxiliary channel passes through the extension tube and the extension ball at the same time, and multiple air flow holes are distributed on the extension tube and the extension ball. The length direction of the extension tube is the radial direction of the central axis column, the cross-section of the extension tube is an ellipse, and the short axis direction of the ellipse is parallel to the length direction of the central axis column.

[0019] The effect is that: according to the shape of the extension tube, the extension tube has a higher degree of elastic bending deformation in the direction of movement of the top plate, and has a higher resistance to deformation in the direction of rotation of the adjustment frame, so the extension body can move the rubber plug more smoothly, and the structural stress on the extension tube is also smaller during the process of the rubber plug being squeezed toward the bottom plate.

[0020] Preferably, a plurality of air discharge holes are provided on the machine body, the hole axis direction of the air discharge holes is the radial direction of the vibrating screen, and the plurality of air discharge holes are distributed in an array along the circumference of the vibrating screen.

[0021] Preferably, the helix angle of the adjustment rib (2) relative to the central axis column (4) ranges from 50° to 70°.

[0022] The effect is that: the helix angle of the adjusting rib is greater than 50°, so that the vertical force it is subjected to can be decomposed into a lateral component and has a rotation tendency under the push of this component; the helix angle is less than 70°, which to a certain extent ensures that the adjusting frame can be pushed to rotate a larger lateral angle when the vertical stroke of the top plate is limited.

[0023] By adopting the above technical solution, the beneficial effects of the present invention are:

[0024] The present invention arranges a central axis column with a hot drying hole and an extension body with an air flow hole, so that the emission point of the hot drying air flow is located inside the vibrating screen and at the place where the rubber stoppers are most accumulated. The hot drying air flow flows from the inside of the vibrating screen to the outside of the vibrating screen. At the same time, the emission position and emission direction of the hot drying air flow are diverse, thereby improving the effective utilization rate of the hot drying air flow and the overall drying efficiency of batch rubber stoppers.

[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] The following combination Figures 1 to 7 The present invention describes a drying device for producing rubber stoppers.

[0036] This embodiment discloses a drying device for rubber stopper production. Figure 1As shown, the apparatus comprises a body 1, a vibrating screen 3, and a vibrating mechanism 2. The vibrating screen 3 is used to hold batches of cleaned rubber stoppers. Both the body 1 and the vibrating screen 3 are cylindrical, with a drying chamber 12 defined within the body 1. The vibrating mechanism 2 is used to cause the vibrating screen 3 to periodically reciprocate within the body 1. When the vibrating screen 3 is within the body 1, it is coaxial with the body 1, and the vibrating screen 3 moves in its own axial direction.

[0037] like Figure 1 and Figure 2 As shown, the axis of the machine body 1 is vertical, and the vibration mechanism 2 is located in the drying chamber 12. It includes a drive motor 21, a drive disc 22, a drive connecting rod 23, and a connecting seat 24. The drive motor 21 is fixedly connected to the machine body 1, and the drive disc 22 is coaxially fixedly connected to the output shaft of the drive motor 21. The axis of the drive disc 22 is horizontal. One end of the drive connecting rod 23 is hinged to the drive disc 22, and the hinge axis is parallel to the axis of the drive disc 22, and the hinge point is eccentric relative to the drive disc 22. The connecting seat 24 is coaxial with the machine body 1 and is slidably connected, with the sliding direction being the axial direction of the machine body 1. The other end of the drive connecting rod 23 is hinged to the connecting seat 24, thereby forming a crank slider mechanism of the vibration mechanism 2. When the drive motor 21 is started, the connecting seat 24 moves vertically back and forth in the machine body 1, and the movement speed varies sinusoidally.

[0038] like Figure 1 、 Figure 3 and Figure 4As shown, the vibrating screen 3 includes a bottom plate 31, a top plate 32, a mounting ring plate 334 and a plurality of connecting columns 33. The bottom plate 31 and the top plate 32 are parallel and coaxial. The plurality of connecting columns 33 are arranged in a circumferential array around the vibrating screen 3. One end of the connecting column 33 is connected to the bottom plate 31, and the other end is connected to the top plate 32. Dense pores (not shown in the figure) are formed on the bottom plate 31 and the top plate 32, and a gap is formed between each two adjacent connecting columns 33. During the reciprocating movement of the vibrating screen 3, moisture on the rubber plug can be thrown out of the vibrating screen 3 through the pores and gaps. The connecting column 33 is elastically deformable along its length and comprises a fixed cylinder 331 and a movable column 332. One end of the fixed cylinder 331 is fixedly connected to the bottom plate 31, while one end of the movable column 332 is detachably connected to the top plate 32 via a mounting ring plate 334. The other end of the movable column 332 is coaxially inserted into the fixed cylinder 331. A movable spring 333 is fixedly connected between the movable column 332 and the fixed cylinder 331, thereby allowing the relative distance between the top plate 32 and the bottom plate 31 to be elastically changed. The mounting ring plate 334 is coaxial with the bottom plate 31 and is simultaneously fixedly connected to all the movable columns 332. The top plate 32 and the mounting ring plate 334 are connected by bolts that pass vertically through the top plate 32 and screw into the mounting ring plate 334. When the top plate 32 is not installed, the top of the vibrating screen 3 is open, allowing the stack of rubber plugs to be placed therein. Once the top plate 32 and the mounting ring plate 334 are connected, the rubber plugs are stably sealed within the vibrating screen 3. In order to improve the convenience of operation, the bolt adopts a butterfly bolt 34.

[0039] like Figure 2 、 Figure 3 and Figure 5 As shown, a central column 4 is coaxially disposed in the middle of the vibrating screen 3. The central column 4 and the bottom plate 31 are relatively fixed in the axial direction and can rotate relative to each other in the circumferential direction. A clearance hole 321 is provided in the middle of the top plate 32 for the central column 4 to pass through. One end of the central column 4 passes through the bottom plate 31 and is coaxially fixedly connected to a connecting threaded barrel 43. The connecting threaded barrel 43 is located on the side of the bottom plate 31 facing away from the top plate 32. A threaded column 241 is fixedly connected to the connecting seat 24, and a plurality of positioning pins 242 are fixedly connected to the side of the connecting seat 24 facing the bottom plate 31. A plurality of positioning holes 311 are provided on the bottom plate 31 for the positioning pins 242 to pass through. The axes of the positioning pins 242 and the positioning holes 311 are parallel to the axis of the central axis column 4; the axial length of the positioning pins 242 is greater than the axial length of the threaded column 241. During the installation of the vibrating screen 3 and the connecting seat 24, when the positioning pins 242 and the positioning holes 311 are aligned one by one, the connecting threaded cylinder 43 and the threaded column 241 are also coaxially aligned, and then the vibrating screen 3 continues to descend and the central axis column 4 is rotated, and the connecting threaded cylinder 43 and the threaded column 241 are threadedly connected. When the bottom plate 31 is away from the side of the top plate 32 and abuts against the connecting seat 24, the connecting seat 24 and the vibrating screen 3 are relatively fixed.

[0040] like Figure 1 、 Figure 2 and Figure 3 As shown, a drying tube 13 is fixedly connected to the housing 1. This tube 13 is a flexible hose, one end of which is fixedly mounted on the connector 24 and the other end is connected to an external drying air source (not shown). A drying channel 41 is coaxially defined within the central column 4. The bottom end of this channel 41 extends through the lumen of the connecting threaded barrel 43. The connector 24 also has a channel for drying air. After the drying air source is supplied, the drying air within the drying tube 13 can pass through the connector 24 and enter the drying channel 41 from the bottom of the central column 4. A plurality of heat drying holes 42 connected to the heat drying channel 41 are provided on the side wall of the central axis column 4. The plurality of heat drying holes 42 are arranged in multiple columns and rows on the central axis column 4. The heat drying holes 42 in each row are arranged in the circumferential direction of the central axis column 4, and the heat drying holes 42 in each column are arranged in the axial direction of the central axis column 4. The length direction of each heat drying hole 42 is the radial direction of the central axis column 4. The heat drying airflow in the heat drying channel 41 eventually flows out from the heat drying holes 42, enters the internal space of the vibrating screen 3 and contacts the rubber stopper.

[0041] like Figure 1 and Figure 4 As shown, the sidewall of the machine body 1 is provided with a plurality of air discharge holes 11. These holes 11 are arranged in an array circumferentially around the vibrating screen 3, with all holes 11 oriented radially with respect to the vibrating screen 3. These holes 11 connect the drying chamber 12 with the exterior of the machine body 1. The hot drying air within the vibrating screen 3 flows out through the pores or gaps in the vibrating screen 3 and is ultimately discharged from the machine body 1 through the air discharge holes 11.

[0042] like Figure 3 、 Figure 5 and Figure 6As shown, the central column 4 is coaxially connected to the adjustment frame 5. The adjustment frame 5 is located on the side of the bottom plate 31 facing the top plate 32. The adjustment frame 5 is provided with multiple extension bodies 54. The adjustment frame 5 includes a connecting ring tube 51, which is coaxially sleeved outside the central column 4 and aligned with one of the heat exhaust holes 42. The inner cavity of the connecting ring tube 51 is connected to the heat exhaust hole 42. The extension body 54 includes an extension tube 541 and an extension ball 542. One end of the extension tube 541 is fixedly connected to the connecting ring tube 51, and the other end is fixedly connected to the extension ball 542. The extension body 54 is provided with an auxiliary channel 543, which is connected to the inner cavity of the connecting ring tube 51 and passes through both the extension tube 541 and the extension ball 542. Both the extension tube 541 and the extension ball 542 are provided with multiple airflow holes 544, which communicate with the auxiliary channel 543. A portion of the hot drying airflow can enter the auxiliary channel 543 through the connecting ring tube 51, ultimately exiting through the airflow holes 544 and contacting the rubber stopper. This increases the spatial location and direction diversity of the hot drying airflow entering the vibrating screen 3, thereby improving drying efficiency. In this embodiment, there are four extension bodies 54, arranged in a circumferential array around the central axis 4, with the length of the extension tube 541 oriented radially with respect to the vibrating screen 3.

[0043] like Figure 3 、 Figure 4 and Figure 5As shown, the adjustment frame 5 also includes three adjustment ribs 52 and three stabilizing ribs 53. The extension trajectory of the adjustment ribs 52 is a spiral line around the axis of the central column 4, and the spiral pitch angle of the adjustment ribs 52 relative to the central column 4 ranges from 50° to 70°. The length direction of the stabilizing ribs 53 is parallel to the length direction of the central column 4. A single stabilizing rib 53 corresponds to one adjustment rib 52, and the adjustment rib 52 is fixedly connected to the end of the stabilizing rib 53 away from the bottom plate 31. The three stabilizing ribs 53 and the three adjustment ribs 52 are arranged in a circumferential array around the central column 4. The top plate 32 is provided with an adjustment slot 322 located on the wall of the clearance hole 321, through which the stabilizing rib 53 or the adjustment rib 52 passes. In its natural state, the top plate 32 is within the length range of the stabilizing rib 53. During the upward deceleration or downward acceleration of the vibrating screen 3, inertia causes the top plate 32 to move relatively away from the bottom plate 31, extending the movable spring 333 and increasing the internal space of the vibrating screen 3. The top plate 32 then moves within the length of the adjustment rib 52. Due to the relative inclination of the adjustment rib 52, the walls of the adjustment slot 322 exert a lateral abutment on the adjustment rib 52, causing the adjustment frame 5 to be thrust perpendicular to the axis of the central column 4. This causes the adjustment frame 5 to rotate, and the extension 54 to rotate accordingly. This not only actuates the rubber stoppers but also increases the positional diversity of the airflow holes 544, further enhancing the drying effect. Furthermore, the gaps between the rubber stoppers are now larger, and the stacked rubber stoppers pose less resistance to the rotation of the extension 54. To reduce friction between the walls of the adjustment slot 322 and the adjustment rib 52, balls can be embedded in the walls of the adjustment slot 322, which roll against the adjustment rib 52.

[0044] like Figure 3 、 Figure 4 and Figure 5 As shown, on the contrary, during the process of the vibrating screen 3 decelerating downward or accelerating upward, the top plate 32 moves relatively close to the bottom plate 31. When the top plate 32 moves within the length range of the stabilizing rib 53, the movement of the top plate 32 will not cause the adjusting frame 5 to rotate; until the movable spring 333 is in a compressed state, the top plate 32 continues to move close to the bottom plate 31, and the top plate 32 may squeeze or collide with the rubber plug, thereby increasing the physical force of the vibrating screen 3 on the rubber plug, thereby promoting the separation of water on the rubber plug.

[0045] like Figure 5 and Figure 7As shown, the cross-section of the extension tube 541 is an ellipse, the short axis direction of the ellipse is parallel to the length direction of the central axis column 4, and the hole axis of the air flow hole 544 on the extension tube 541 is parallel to the short axis direction of the ellipse; therefore, the extension tube 541 has a higher degree of elastic bending deformation in the vertical direction and a higher ability to resist deformation in the lateral direction. The extension body 54 moves the rubber plug laterally more smoothly, and the structural stress on the extension tube 541 is also smaller during the process of the rubber plug being squeezed toward the bottom plate 31.

[0046] The working process of this embodiment:

[0047] After the rubber stopper is placed in the vibrating screen 3, the vibrating screen 3 is fixed to the connecting seat 24. The hot drying airflow is introduced into the hot drying pipe 13, and the hot drying gas flows from the middle of the vibrating screen 3 to the outside. At the same time, the vibrating mechanism 2 is started to make the vibrating screen 3 move back and forth. During each movement cycle, the adjusting frame 5 carries each extension body 54 to swing back and forth in both directions once. Under the vibration action of the vibrating screen 3, the steering action of the extension body 54 and the heating action of the hot airflow, the moisture on the rubber stopper is quickly separated from the rubber stopper.

[0048] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
