Description

Technical Field

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

[0002] A rubber stopper is a sealing device made of rubber, which has the advantages of dust prevention, water prevention, wear resistance, tear resistance, aging resistance, oil resistance, ozone resistance, etc. Chemical or medical containers can be sealed through rubber stoppers. After the rubber stopper is formed, there will be some impurities such as dust and oil film remaining on its surface, and it needs to be cleaned and dried before being packaged into finished products.

[0003] The Chinese patent document with the publication number CN218210421U discloses a drying device for medical rubber stopper production, including four sets of legs, a support table, a drying device body, a heat dissipation pipe, a drying box, a feed pipe, a drying sieve, a connecting rod, a rotating wheel, a support plate, a rotating shaft and a servo motor. A working cavity is arranged inside the drying box, a sliding groove is arranged in the middle of the outer wall of the working cavity, and multiple sets of heat dissipation holes are arranged on the heat dissipation pipe; the drying sieve is located inside the working cavity, and a batch of rubber stoppers are placed in the drying sieve, and the drying sieve swings up and down to shake off the 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 solution, the operation mode of the drying sieve is vertical up-and-down periodic movement. A batch of rubber stoppers are stacked in the drying sieve. When the stacking density of the rubber stoppers in the drying sieve is relatively large, the rubber stoppers in the middle are least likely to come into contact with the drying air flow. Moreover, due to the relatively high elasticity of the rubber stoppers themselves, during the up-and-down vibration of the drying sieve, the vibration effect on the rubber stoppers in the middle is relatively weak, and the moisture on them is not easily separated, and the moisture here is the most difficult to flow out, that is, the drying efficiency of the rubber stoppers in the middle of the drying sieve is relatively low. Summary of the Invention

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

[0006] A drying device for rubber stopper production of the present invention comprises a machine body, a vibration mechanism and a vibration screen for containing rubber stoppers, the machine body is connected with a hot drying pipe, the hot drying pipe is used to convey airflow into a drying chamber, the vibration mechanism is used to control the vibration screen to perform periodic movement in the machine body, a central axis column is coaxially connected to the middle of the vibration screen, a hot drying channel is provided in the central axis column, the central axis column and a 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 is connected to the hot drying pipe; the vibration 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 an adjustment frame, and a plurality of extension bodies are fixedly connected to the adjustment frame, and the extension bodies extend 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, and 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 airflow can enter the auxiliary channel and eventually flow out from the airflow hole and contact the rubber plug, thereby increasing the spatial position points and direction diversity of the hot drying airflow 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 reciprocates to make the rubber plugs inside it shake, and the moisture on the rubber plugs is easier to separate; the central axis column and the vibrating screen are coaxial, that is, the central axis column is located in the middle of the vibrating screen, where the rubber plugs are piled up to the maximum, and the hot drying pipe transports hot air to the central axis 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 where the rubber plugs are connected with the maximum density in the vibrating screen is affected by the hot drying air flow to the maximum, 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 axis column, so that the adjusting frame rotates, and the extension body also rotates accordingly. On the one hand, it has a toggling effect on the rubber stoppers, and on the other hand, it also increases the diversity of the position 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. 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, the other end of the movable column is coaxially inserted into the fixed cylinder, and 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 enables 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 action of inertia, the top plate continuously moves closer to and away from the bottom plate, the internal space size of the vibrating screen constantly changes, and the shaking degree and mutual collision degree of the rubber plugs inside it are higher, which is more conducive to the separation of moisture.

[0011] Preferably, the vibrating screen further includes a mounting ring plate, the mounting ring plate is coaxial with the bottom plate, the mounting ring plate is fixedly connected to all the 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 to the connecting column through the mounting ring plate. After removing the top plate, the upper part of the vibrating screen is open, which is convenient for putting the rubber plugs into it.

[0013] Preferably, the vibrating mechanism includes a connecting seat, the connecting seat is slidably connected to the machine body in the vertical direction, the connecting seat is connected to the vibrating screen, the central axis column is rotatably connected to the bottom plate coaxially, one end of the central axis column passes through the bottom plate and is fixedly connected with 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 bottom 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 bottom plate, positioning holes for the positioning pins to pass through are formed in the bottom plate, the axes of the positioning pins and the positioning holes are both 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. Then, the vibrating screen is continuously lowered and the central axis column is rotated, and the connecting threaded cylinder and the threaded column are threadedly connected. 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 adjusting frame further includes stabilizing rib strips, the number of the stabilizing rib strips is the same as that of the adjusting rib strips and the two are connected in one-to-one correspondence. The length direction of the stabilizing rib strips is parallel to the length direction of the central axis column. The stabilizing rib strips are located at the end of the adjusting rib strips facing the bottom plate. The adjusting groove also allows the stabilizing rib strips to pass through. In the natural state, the stabilizing rib strips are located in the adjusting 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, 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 adjusting 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 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 adjusting rib (2) relative to the central axis column (4) is in the range of 50°-70°.

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

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

Detailed implementation manners

[0032] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0033] The following will be combined with Figures 1 to 7 to describe a drying device for producing rubber plugs according to the present invention.

[0034] This embodiment discloses a drying device for producing rubber plugs, as shown in Figure 1As shown in the figure, it includes a machine body 1, a vibrating screen 3 and a vibration mechanism 2. The vibrating screen 3 is used to hold a batch of rubber stoppers after cleaning. Both the machine body 1 and the vibrating screen 3 are cylindrical. A drying chamber 12 is provided inside the machine body 1. The vibration mechanism 2 is used to make the vibrating screen 3 move periodically back and forth inside the machine body 1. When the vibrating screen 3 is located inside the machine body 1, it is coaxial with the machine body 1, and the moving direction of the vibrating screen 3 is its own axis direction.

[0035] As Figure 1 and Figure 2 shown in the figure, the axis of the machine body 1 is in the vertical direction. The vibration mechanism 2 is located inside the drying chamber 12 and includes a driving motor 21, a driving disk 22, a driving connecting rod 23 and a connecting seat 24. The driving motor 21 is fixedly connected to the machine body 1. The driving disk 22 is coaxially and fixedly connected to the output shaft of the driving motor 21. The axis of the driving disk 22 is in the horizontal direction. One end of the driving connecting rod 23 is hinged to the driving disk 22. The hinge axis is parallel to the axis of the driving disk 22 and the hinge point is eccentrically arranged relative to the driving disk 22. The connecting seat 24 is coaxial with the machine body 1 and is slidably connected, and the sliding direction is the axial direction of the machine body 1. The other end of the driving connecting rod 23 is hinged to the connecting seat 24. Thus, the vibration mechanism 2 forms a crank-slider mechanism. When the driving motor 21 is started, the connecting seat 24 moves vertically back and forth inside the machine body 1, and the magnitude of the moving speed changes sinusoidally.

[0036] As 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. Densely distributed pores (not shown in the figure) are formed on the bottom plate 31 and the top plate 32, and a gap is formed between every 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 the gap. The connecting column 33 can be elastically deformed along its length direction, and includes a fixed cylinder 331 and a movable column 332. One end of the fixed cylinder 331 is fixedly connected to the bottom plate 31, one end of the movable column 332 is detachably connected to the top plate 32 through a mounting ring plate 334, and 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, so that the relative distance between the top plate 32 and the bottom plate 31 can be elastically changed. The mounting ring plate 334 is coaxial with the bottom plate 31, and the mounting ring plate 334 is fixedly connected to all the movable columns 332 at the same time. The top plate 32 and the mounting ring plate 334 are connected by bolts, and the bolts vertically pass through the top plate 32 and are screwed into the mounting ring plate 334; when the top plate 32 is not installed, the upper part of the vibrating screen 3 is open, which is used to place the piled rubber plugs therein. After the top plate 32 and the mounting ring plate 334 are connected, the rubber plugs are stably sealed in the vibrating screen 3. In order to improve the convenience of operation, the bolt adopts a butterfly bolt 34.

[0037] like Figure 2 , Figure 3 and Figure 5 As shown, a central axis column 4 is coaxially arranged in the middle of the vibrating screen 3. The central axis column 4 and the bottom plate 31 are relatively fixed in the axial direction and can rotate relatively in the circumferential direction. A clearance hole 321 for the central axis column 4 to pass through is opened in the middle of the top plate 32. One end of the central axis column 4 passes through the bottom plate 31 and is coaxially fixedly connected with a connecting threaded barrel 43, which is located on the side of the bottom plate 31 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 accordingly, and 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 is continued 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.

[0038] likeFigure 1 , Figure 2 and Figure 3 As shown in Figure 1 , Figure 2 and Figure 3 , a hot air drying pipe 13 is fixedly connected inside the machine body 1. The hot air drying pipe 13 is a flexible pipe. One end of the flexible pipe is fixedly installed on the connecting seat 24, and the other end is externally connected to a hot air drying gas source (not shown in the figure). A hot air drying channel 41 is coaxially opened inside the central axis column 4, and the bottom end of the hot air drying channel 41 penetrates through to the inner cavity of the connecting threaded cylinder 43. A channel for the hot air drying air flow to pass through is also opened on the connecting seat 24. After the hot air drying gas source supplies gas, the hot air drying air flow in the hot air drying pipe 13 can pass through the connecting seat 24 and enter the hot air drying channel 41 from the bottom of the central axis column 4. A plurality of hot air drying holes 42 communicating with the hot air drying channel 41 are opened on the side wall of the central axis column 4. The plurality of hot air drying holes 42 are arranged in multiple columns and multiple rows on the central axis column 4. The arrangement direction of each row of hot air drying holes 42 is the circumferential direction of the central axis column 4, and the arrangement direction of each column of hot air drying holes 42 is the axial direction of the central axis column 4. The length direction of each hot air drying hole 42 is the radial direction of the central axis column 4. The hot air drying air flow in the hot air drying channel 41 finally flows out from the hot air drying holes 42 and enters the internal space of the vibrating screen 3 to contact the rubber plug.

[0039] As Figure 1 and Figure 4 shown in Figure 1 and Figure 4 , a plurality of air discharge holes 11 are opened on the side wall of the machine body 1. The plurality of air discharge holes 11 are arranged in an array along the circumferential direction of the vibrating screen 3, and the hole axis directions of all the air discharge holes 11 are the radial direction of the vibrating screen 3. The air discharge holes 11 communicate the drying cavity 12 and the external space of the machine body 1. The hot air drying air flow in the vibrating screen 3 flows out through the pores or gaps on the vibrating screen 3 and finally flows out of the machine body 1 through the air discharge holes 11.

[0040] As Figure 3 , Figure 5 and Figure 6As shown, the central axis column 4 is coaxially and rotationally connected to an adjusting frame 5. The adjusting frame 5 is located on the side of the bottom plate 31 facing the top plate 32. A plurality of extension bodies 54 are provided on the adjusting frame 5. The adjusting frame 5 includes a connecting ring pipe 51. The connecting ring pipe 51 is coaxially sleeved outside the central axis column 4 and is aligned with one row of heat drying holes 42. The inner cavity of the connecting ring pipe 51 communicates with this row of heat drying holes 42. The extension body 54 includes an extension pipe 541 and an extension ball 542. One end of the extension pipe 541 is fixedly connected to the connecting ring pipe 51, and the other end is fixedly connected to the extension ball 542. An auxiliary channel 543 is formed on the extension body 54. The auxiliary channel 543 communicates with the inner cavity of the connecting ring pipe 51. The auxiliary channel 543 passes through the extension pipe 541 and the extension ball 542 at the same time. A plurality of air flow holes 544 are formed on both the extension pipe 541 and the extension ball 542. The air flow holes 544 communicate with the auxiliary channel 543. Part of the heat drying air flow can enter the auxiliary channel 543 through the connecting ring pipe 51 and finally flow out from the air flow holes 544 to contact the rubber plug. Thereby, the diversity of the spatial position points and directions of the heat drying air flow entering the vibrating screen 3 is improved, and the drying efficiency is improved. In this embodiment, there are four extension bodies 54 in total. The four extension bodies 54 are arranged in a circumferential array around the central axis column 4, and the length direction of the extension pipe 541 is the radial direction of the vibrating screen 3.

[0041] As 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 axis column 4, and the spiral rise angle of the adjustment ribs 52 relative to the central axis column 4 is between 50° and 70°. The length direction of the stabilizing ribs 53 is parallel to the length direction of the central axis column 4. A single stabilizing rib 53 corresponds to one adjustment rib 52. 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 axis column 4. An adjustment groove 322 for the stabilizing ribs 53 or the adjustment ribs 52 to pass through is provided on the top plate 32 and on the wall of the clearance hole 321. In a natural state, the top plate 32 is located within the length range of the stabilizing ribs 53. During the process of the vibration screen 3 decelerating upward or accelerating downward, under the action of inertia, the top plate 32 moves relatively away from the bottom plate 31, the movable spring 333 stretches, the internal space of the vibration screen 3 becomes larger, and the top plate 32 moves into the length range of the adjustment rib 52. Since the adjustment rib 52 is relatively inclined, the groove wall of the adjustment groove 322 generates a lateral abutment force on the adjustment rib 52, and the adjustment frame 5 is subjected to a thrust perpendicular to the axis direction of the central axis column 4, so that the adjustment frame 5 rotates, and the extension body 54 also rotates accordingly, which has a toggling effect on the rubber plug on the one hand, and on the other hand, it also increases the position diversity of the air flow hole 544, further improving the heat drying effect. At the same time, the gap between the rubber plugs is also enlarged at this moment, and the piled rubber plugs have less rotation resistance to the extension body 54. In order to reduce the friction between the groove wall of the adjustment groove 322 and the adjustment rib 52, a ball can be embedded in the groove wall of the adjustment groove 322, and the ball and the adjustment rib 52 are in rolling contact.

[0042] like Figure 3 , Figure 4 and Figure 5 As shown, on the contrary, during the process of the vibration 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 stable rib 53, the movement of the top plate 32 will not cause the adjustment 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 vibration screen 3 on the rubber plug, thereby promoting the separation of water on the rubber plug from the rubber plug.

[0043] like Figure 5 and Figure 7As shown, the cross-section of the extension tube 541 is elliptical. The minor axis direction of the ellipse is parallel to the length direction of the central axis column 4, and the axis of the air flow hole 544 on the extension tube 541 is parallel to the minor axis direction of the ellipse. Thus, the elastic bending deformation degree of the extension tube 541 in the vertical direction is relatively high, and the anti-deformation ability in the horizontal direction is relatively high. When the extension body 54 horizontally toggles the rubber plug, it is smoother, and the structural stress on the extension tube 541 during the process of the rubber plug extruding towards the bottom plate 31 is also smaller.

[0044] The working process of this embodiment: After placing the rubber plug into the vibrating screen 3, the vibrating screen 3 is fixed to the connecting seat 24. The hot air drying tube 13 passes hot air drying flow. The hot air flows from the middle of the vibrating screen 3 to the outside. At the same time, the vibration mechanism 2 is started to make the vibrating screen 3 reciprocate. For each movement cycle, the adjusting frame 5 drives each extension body 54 to swing back and forth bidirectionally once. Under the vibration of the vibrating screen 3, the toggling of the extension body 54, and the hot air drying of the hot air flow, the moisture on the rubber plug quickly separates from the rubber plug.

[0045] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
