Description

Technical Field

[0001] This utility model relates to the field of product drying technology, and in particular to a drying device. Background Technology

[0002] During the production of extruded tubes, the extruded tubes produced from the extruder in the previous process are soaked in water. When the extruded tubes are taken out of the water, many water droplets remain on the surface and inside. It is impossible to dry every corner of the extruded tube manually with an air gun. Some automatic drying devices can only dry the outside of the tube, leaving water droplets inside. This results in water stains on the tube, which has an adverse effect on the appearance and quality of the product. Utility Model Content

[0010] The power component is a cylinder.

[0011] The multiple air inlets are arranged at intervals, and the interval between the air inlets is the same as the arrangement distance of the tube body. The center of the air inlet coincides with the center of the tube body.

[0012] The stepping conveying mechanism includes a first motor, a linkage mechanism, and a conveying frame. The first motor drives the linkage mechanism to rotate. One end of the linkage mechanism is connected to the output shaft of the first motor, and the other end of the linkage mechanism is rotatably connected to the conveying frame.

[0026] Please see Figures 1 to 4 , Figure 1 This is a schematic diagram of the drying device of this utility model, used to dry the tube 10. The tube 10 can be a round tube, square tube, triangular tube, or irregularly shaped tube, and the material can be metal, silicone, rubber, plastic, or polymer. This specification uses a silicone extruded round tube as an example of the tube 10. The extruded tube is a product made of silicone into a continuous tubular shape through a certain processing technology. During production, it is immersed in water, so many water droplets remain on the surface and inside of the extruded tube after it is removed from the water. These water droplets and stains need to be dried before it can be used normally. For ease of explanation, the two ends along the length of the tube 10 are defined as the first end and the second end, respectively.

[0027] The drying device of this application includes a frame 1, a stepping conveyor mechanism 2, a tube rotation mechanism 3, and a blower mechanism. The stepping conveyor mechanism 2 and the blower mechanism are mounted on the frame 1. The stepping conveyor mechanism 2 is adjacent to the extruded tube production line and receives the produced tubes 10, used to convey the tubes 10 to the tube rotation mechanism 3. The tube rotation mechanism 3 is used to drive the tubes 10 to rotate circumferentially, thereby facilitating the blower mechanism to dry the entire outer surface of the tubes 10 without leaving water droplets or stains. The blower mechanism includes a side blower mechanism 4 and an outer blower mechanism 5. The side blower mechanism 4 is used to blow air onto one end of the tubes 10 in the axial direction, thereby drying the inside of the tubes 10, and the water droplets inside the tubes are discharged through the other end. The outer blower mechanism 5 is used to blow air onto the outer surface of the tubes 10, drying the water droplets and stains on the outer surface of the tubes 10. The side blower mechanism 4 and the external blower mechanism 5 work together to dry the inside and surface of the tube 10, achieving the required standard for use.

[0028] The side-blowing mechanism 4 is located at the first end of the tube body 10 along its axial direction. The side-blowing mechanism 4 includes a first fan 41 and multiple air outlets 42 connected to the first fan 41. The air outlets 42 are opposite to the inner wall of the tube body 10. The first fan 41 provides an air source, discharging gas through the air outlets 42. In one embodiment, the side-blowing mechanism 4 generates a wind force of 0.5 MPa, and the blowing time for a single tube body 10 is 6 seconds. The air outlets 42 are positioned directly opposite the first or second end of the tube body 10, blowing water droplets and stains from the tube wall out from the other end, ensuring the inside of the tube body 10 is dry and free of water stains, meeting the usage standards.

[0029] The external blower mechanism 5 includes a power unit 51, a second blower 52, and an air knife 53. The power unit 51 drives the air knife 53 to slide axially along the pipe body 10. The air knife 53 is connected to the second blower 52, and the air outlet of the air knife 53 is opposite to the outer wall of the pipe body. The second blower 52 generates compressed air. After the compressed air enters the air knife 53, it generates a thin airflow sheet through the special geometry of the air knife 53 and blows it out at high speed, forming a thin, high-intensity, large-airflow impact air curtain to dry the water droplets and stains on the outer surface of the pipe body 10. The power unit 51 drives the air knife 53 to slide axially along the pipe body 10, reciprocating between the first and second ends of the pipe body 10. At the same time, the aforementioned pipe body rotation mechanism 3 drives the pipe body 10 to rotate, ensuring that the air knife 53 can blow onto the entire outer surface of the pipe body 10, so that the inner wall and outer surface of the pipe body 10 are dry after passing through the drying device.

[0030] The power component 51 in this application is a cylinder, hydraulic cylinder, or electric cylinder. Preferably, the power component 51 is a cylinder, specifically a rodless cylinder. A rodless cylinder is a cylinder that uses a piston to directly or indirectly connect to an external actuator, causing it to reciprocate along with the piston. The biggest advantage of this type of cylinder is that it saves installation space. In this embodiment, the power component 51 is a rodless cylinder, which reduces the required installation space and enables reciprocating motion, driving the air knife 53 to reciprocate along the length of the support frame 54, thereby drying the outer surface of the tube body 10.

[0031] In this application, the frame 1 includes a first frame 11 and a second frame 12, which are arranged axially along the tube 10 and correspond to one end of the tube 10 along its axial direction. In one embodiment, the first frame 11 and the second frame 12 correspond to the first end and the second end of the tube 10, respectively. A certain length is spaced between the first frame 11 and the second frame 12 to allow for accommodating space. A tube rotation mechanism 3 is located between the first frame 11 and the second frame 12. When the first frame 11 and the second frame 12 are placed on a flat surface, the tube rotation mechanism 3 can be placed on the open space between the first frame 11 and the second frame 12. A side air blower mechanism 4 is installed on the first frame 11 or the second frame 12, opposite to either end of the tube 10. In this embodiment, the side air blower mechanism 4 is installed on the first frame 11, opposite to the first end of the tube 10. An external air blower mechanism 5 is fixed to the top of the first frame 11 and the second frame 12, blowing air downwards from the top of the tube 10. The external blower mechanism 5 and the tube body rotation mechanism 3 are respectively arranged at the upper and lower positions of the tube body 10, and their layout is compact and saves space.

[0032] In this application, the side blower mechanism 4 has multiple air outlets 42, which facilitates the simultaneous drying of multiple tubes 10, thereby improving work efficiency. The multiple air outlets 42 are spaced apart and evenly arranged on a horizontal plane, and the distance between two adjacent air outlets 42 is the same as the arrangement distance of the multiple tubes 10. The center of the air outlet 42 coincides with the center of the tube 10, which facilitates the uniform drying of the inner wall of the tube 10.

[0033] The air blower mechanism 5 in this application also includes a support frame 54. The two ends of the support frame 54 are fixed to the first frame 11 and the second frame 12 respectively. The power component 51 is installed on the support frame 54, and the power output end of the power component 51 can extend and retract along the length of the support frame 54, thereby driving the air knife 53 to reciprocate.

[0034] Please see Figure 3 In this application, the stepping conveyor mechanism 2 includes a first motor 21, a linkage mechanism 22, and a conveyor frame 23. The first motor 21 drives the linkage mechanism 22 to rotate. One end of the linkage mechanism 22 is connected to the output shaft of the first motor 21, and the other end of the linkage mechanism 22 is rotatably connected to the conveyor frame 23. The linkage mechanism 22 can drive the conveyor frame 23 to reciprocate up and down. The conveyor frame 23 is used to carry the tube 10 and convey the tube 10 to the tube rotating mechanism 3. Specifically, the linkage mechanism 22 includes a transmission rod, a first rotating shaft, an arc-shaped rotating shaft, and a second rotating shaft in sequence. The transmission rod is connected to the output shaft of the first motor 21, the first rotating shaft is rotatably connected to the transmission rod, and the two ends of the arc-shaped rotating shaft are rotatably connected to the first rotating shaft and the second rotating shaft, respectively. The second rotating shaft is rotatably connected to the frame 1, and the arc-shaped rotating shaft is also rotatably connected to the conveyor frame 23. The first motor 21 drives the first rotating shaft to rotate via a transmission rod. The first rotating shaft then drives the arc-shaped rotating shaft and the second rotating shaft to rotate in sequence, thus enabling the conveyor frame 23 to move downwards, forwards, upwards, and backwards back to its original position in one rotation cycle. When the conveyor frame 23 moves downwards, the extruded tube abuts against the tube body rotating mechanism 3, and the tube body 10 remains on the tube body rotating mechanism 3. When the tube body 10 is dried, the conveyor frame 23 returns to its original position, lifting the tube body 10, and the tube body 10 returns to the conveyor frame 23, thus transferring the dried tube body 10 to the next process.

[0035] Preferably, in this application, the first motor 21 is a stepper motor. A stepper motor is a discrete control motor that converts electrical pulse excitation signals into corresponding angular or linear displacement values. This type of motor moves one step for each input electrical pulse, so it is also called a pulse motor. The first motor 21 drives the linkage mechanism 22 to move, thereby completing the steps of feeding, drying, and unloading the tube 10, realizing the full automation of the drying process.

[0036] Please see Figure 4In this application, the tube rotation mechanism 3 includes a second motor 31, a synchronous belt 32, a transmission wheel 33, and rollers 34. The second motor 31 drives the synchronous belt 32 to move, and the synchronous belt 32 is wound around the transmission wheel 33. The transmission wheel 33 and rollers 34 are coaxially fixed, and the transmission wheel 33 drives the rollers 34 to rotate. The tube 10 is placed between two adjacent rollers 34. There are multiple transmission wheels 33 and rollers 34, which are arranged sequentially along the same plane. The diameter of the rollers 34 is larger than the diameter of the transmission wheels 33. The transmission wheels 33 and rollers 34 rotate in the same direction. The tube 10 is driven to rotate by two adjacent rollers 34, and the rotation direction of the tube 10 is also the same as the rotation direction of the rollers 34.

[0037] The tube body rotation mechanism 3 in this application also includes a pressing roller 35. The pressing roller 35 and the transmission wheel 33 are offset in the vertical plane. The pressing roller 35 is arranged between two adjacent transmission wheels 33. The synchronous belt 32 is wound around the transmission wheel 33 and the pressing roller 35 in sequence. The pressing roller 35 is used to tighten the synchronous belt 32.

[0038] The drying device in this application also includes a water stain collection tank, which is placed on a flat ground and corresponds to the second end position of the tube 10 in the axial direction, for receiving water droplets and water stains blown out from the tube 10.

[0039] Using the drying device of this invention, the surface and inner wall of the tube are automatically dried, leaving no water droplets or stains inside or outside the tube. The drying effect is uniform inside and out, resulting in good drying performance. Furthermore, it can be conveyed while blowing air, greatly improving production efficiency.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
