Description

Technical Field

[0001] The invention relates to the field of adhesive tape processing, and in particular to a high-efficiency and energy-saving adhesive tape drying device. Background Art

[0002] As a common industrial and consumer product, adhesive tape is widely used in packaging, bonding, sealing and protection. Its production process usually includes steps such as substrate preparation, gluing, drying and winding. During the drying stage of tape production, the glued tape needs to be removed by a specific device to remove the moisture or solvent in the adhesive to ensure the adhesive performance and stability of the tape surface. However, the traditional tape drying technology still has the following shortcomings in practical applications:

[0003] Traditional tape drying devices usually use a linear conveying method to dry the tape surface through hot air or infrared heating. Although this method is mature in technology, the drying efficiency is low due to the limited contact area between the drying gas and the tape surface and the short flow path. Especially for wide tapes or scenes that require efficient production, it is difficult to meet the high-efficiency requirements of modern industrial production.

[0004] In conventional drying devices, the flow path of the drying gas in the cavity is complex and uneven, and some of the gas is not fully utilized and is directly discharged, resulting in energy waste. At the same time, moisture is easily retained in the drying cavity during the traditional drying process, affecting the drying efficiency and increasing energy consumption.

[0005] In the linear conveying drying mode, the strength of the drying airflow that the tape contacts at different positions may be different, resulting in uneven drying of the tape surface. This unevenness will affect the performance of the tape adhesive and reduce the quality stability of the tape.

[0006] Traditional drying devices usually require the dried tape to be readjusted or transported to the winding device, which increases the operation steps and equipment complexity and reduces production efficiency;

[0007] Although some devices are currently equipped with dry gas recovery systems, due to design limitations, the recovery efficiency is low, making it difficult to achieve multiple uses of dry gas, which increases operating costs and environmental burdens. Summary of the invention

DETAILED DESCRIPTION

[0036] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0037] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0038] like Figure 1 As shown, an efficient and energy-saving adhesive tape drying device of the present invention comprises a bottom shell 8, wherein the bottom shell 8 has a drying chamber 27, and a tape placement position is formed on one side of the drying chamber 27. The adhesive tape to be dried is arranged in a spiral shape at the tape placement position. When drying, the adhesive tape to be dried is arranged in a spiral shape and placed in the drying chamber 27 to complete the installation.

[0039] It also includes a rotary drive mechanism, which is installed on the lower end surface of the bottom shell 8 and corresponds to the tape placement position. The driving end of the rotary drive mechanism is installed with a winding drum 30, and the winding drum 30 is positioned and installed at the center of the spiral tape 11 and is fixedly connected to the center of the center of the tape. When drying is completed, the spiral tape 11 can be directly wound up by the rotary drive mechanism without moving to other winding stations.

[0040] It also includes a sealing cover 1, which is connected to the bottom shell 8 in an upper and lower guiding manner. The sealing cover 1 is provided with a detachable sealing part 2 on one side relative to the bottom shell 8. When the sealing cover 1 is closed with the bottom shell 8, the sealing cover 1 and the bottom shell 8 seal the upper and lower sides of the spiral tape 11, and form a dry air inlet end at the outermost end of the spiral tape 11, a spiral drying channel 100 is formed inside the spiral tape 11, and a dry air outlet end is formed at the center of the spiral tape 11. When it is necessary to take out or put in the tape, the sealing cover 1 can be opened vertically to operate. Once the sealing cover 1 is closed relative to the bottom shell 8, the upper and lower sides of the tape can be sealed, so that a spiral drying channel 100 with closed upper and lower sides is formed. Therefore, the dry gas can only be dried along the spiral drying channel 100, input from the outermost side, and gradually move toward the center. The airflow will not be turbulent during the whole process, the length of the drying channel is increased, and the dry gas can be repeatedly contacted with the glue seal to achieve better drying.

[0041] It also includes an exhaust mechanism, which is installed in the sealing cover 1 and is arranged opposite to the winding drum 30. The exhaust mechanism is connected to the dry gas outlet end of the winding drum 30, and the dry gas dried in the drying channel is extracted by the exhaust mechanism and stored in the sealing cover 1. Once the dry gas enters from the outermost end, after passing through the vortex-shaped drying channel 100, the exhaust gas is finally collected at the center by the exhaust mechanism and reused, so as to use energy more reasonably.

[0042] like Figure 4 As shown, it also includes a guide pulling mechanism, which is installed in the drying chamber 27. The guide pulling mechanism is fixedly connected to the opening of the spiral tape 11. When the bottom shell 8 and the sealing cover 1 are in an inclined state, the guide pulling mechanism moves the opening of the tape in a direction away from the winding drum 30 by gravity, and the center position of the spiral tape 11 is gathered on the winding drum 30. During normal drying, the center of the bottom shell 8 is located on one side of the tape, and the guide pulling mechanism will not pull the tape and remain stationary. Once the drying is completed and the tape needs to be wound up, the center of the bottom shell 8 can be controlled, and gravity can be used to make the guide pulling mechanism slide, thereby pulling out the tape, so that the center position of the tape is tightened, and the rotary drive mechanism can be used to wind up the tape.

[0043] like Figure 2 and Figure 5 As shown, the rotary drive mechanism includes a drive motor 13 installed on the bottom surface of the bottom shell 8, and a drive shaft is installed on the output end of the drive motor 13. The drive shaft extends into the drying chamber 27 and is flush with the bottom surface of the drying chamber 27. A rectangular positioning notch is arranged on the top end face of the drive shaft, and the bottom of the winding drum 30 is positioned and installed in the positioning notch. The drive motor 13 is controlled by an external controller. A new winding drum 30 needs to be placed in the winding drum 30 after each winding of the tape. When installing the tape to be dried, it is installed on the outside of the winding drum 30. The winding drum 30 can be driven by the drive motor 13 to rotate in a circle to complete the winding of the dried tape.

[0044] Please continue reading Figure 5 The winding drum 30 has an air extraction chamber 28 with a top opening, and an air extraction opening 31 is provided on the winding drum 30, and the air extraction opening 31 is communicated with the air extraction chamber 28. The dry air flowing through the drying channel enters the air extraction chamber 28 through the air extraction opening 31, and the top of the air extraction chamber 28 is sealed and docked by the air extraction mechanism. A rectangular positioning block 35 is provided at the bottom of the winding drum 30, and the rectangular positioning block 35 is positioned and inserted into the positioning notch. A tape fixing groove 29 is provided on the outer circumferential surface of the winding drum 30, and the central part of the center position of the tape is stuck in the tape fixing groove 29 and fixed by adhesion. Through the rectangular positioning block 35 and the positioning notch, the winding drum 30 can follow the driving motor 13 to make a circular motion, and the dry airflow will eventually pass through the air extraction opening 31 after passing through the vortex-shaped drying channel 100 and enter the air extraction chamber 28, and then be extracted and stored by the air extraction mechanism.

[0045] like Figure 2 and Figure 3As shown, the air extraction mechanism includes an air extraction pump 22, which is installed in the storage chamber 26 in the sealing cover 1, and a conical air extraction joint 19 is installed at the air extraction end of the air extraction pump 22, and the air extraction joint 19 is inserted into the air extraction chamber 28 with a top opening, so as to extract the dry gas in the air extraction chamber 28;

[0046] The output pipeline of the vacuum pump 22 is connected to an elastic air storage bag 24, and the elastic air storage bag 24 is arranged in the storage chamber 26. The vacuum pump 22 is used to fill the extracted dry gas into the elastic air storage bag 24. A one-way air outlet valve is installed on the output pipeline. An air guide hose 21 is provided at the output end of the elastic air storage bag 24, and a solenoid valve is installed on the air guide hose 21. The output end of the air guide hose 21 is connected to a secondary drying mechanism, which is located on one side of the bottom shell 8 and is used for secondary drying of the stretched tape. The extracted hot air will cause the elastic air storage bag 24 to expand elastically, so that the dry gas inside has a larger output force. The one-way air outlet valve prevents the gas in the elastic air storage bag 24 from flowing back. The solenoid valve allows the dry gas in the elastic air storage bag 24 to be stored and can also be output under pressure after opening.

[0047] Please continue reading Figure 3 A baffle 23 is fixedly installed in the storage cavity 26 on one side of the air pump 22, one side of the elastic air storage bag 24 is fixedly connected to the baffle 23, and the other side of the elastic air storage bag 24 is connected to a guide plate 25, and the guide plate 25 is guided and installed in the storage cavity 26. The air pump 22 and the solenoid valve are both controlled by an external controller. After the elastic air storage bag 24 is inflated, it expands and pushes the guide plate 25 to move. Inlet and outlet holes can also be set on the side of the storage cavity 26 away from the baffle 23. When the elastic air storage bag 24 is elastically expanded, the original gas inside can be squeezed out from the inlet and outlet holes.

[0048] like Figure 1 and Figure 3As shown, the secondary drying mechanism includes a gas collecting cylinder 20, which is fixedly mounted on one side of the outer side of the bottom shell 8. The output end of the gas collecting cylinder 20 is provided with one or more air flow nozzles 9 in parallel, and the air flow nozzles 9 are arranged along the length direction of the bottom shell 8, and are used to perform secondary drying on the pulled adhesive tape. The gas collecting cylinder 20 is connected and conducted with the air guide hose 21. When the adhesive tape is pulled out through the guide pulling mechanism, the solenoid valve is opened at this time, and the dry gas filled in the elastic air storage bag 24 can enter the gas collecting cylinder 20, and then be sprayed out by one or more air flow nozzles 9. Since the air flow nozzles 9 correspond to the glue surface of the pulled adhesive tape, the sprayed dry air flow can perform secondary drying on the glue surface of the adhesive tape. The purpose of secondary drying is to make up for some solvents or moisture remaining during the primary drying period, so as to achieve better drying effect. Since the secondary drying part is located during the winding period of the adhesive tape, the time utilization rate can be higher. The secondary drying can be maintained for a period of time after the adhesive tape is pulled out, or the secondary drying can be performed while winding.

[0049] Among them, Figure 4 and Figure 5 As shown, the guide pulling mechanism includes a counterweight slider 10, and guide blocks are arranged on both sides of the counterweight slider 10. The guide blocks are slidably arranged in the guide slide grooves 17 opened on both sides of the drying chamber 27. The counterweight slider 10 is provided with a metal hose 32 with arbitrary bending ability on the side facing the tape. The counterweight slider 10 has an air inlet cavity inside, and the air inlet end of the metal hose 32 is connected and communicated with the air inlet cavity. An air inlet hose 211 is arranged at the air inlet end of the air inlet cavity, and the air inlet hose 211 is connected to the external air pump 4. The air pump 4 is connected to the external dry hot air source. The dry hot air source is input into the air inlet cavity inside the counterweight slider 10 by the air pump 4 through the air inlet hose 211, and then input into the vortex-shaped drying channel 100 by the air inlet hose 211. The metal hose 32 can be bent and adjusted at an angle.

[0050] A clamping claw 34 is provided on the side of the counterweight slider 10 facing the tape, and a clamping cavity is opened in the middle of the clamping claw 34. The opening of the tape is inserted into the clamping cavity. A locking piece 33 is provided on one side of the clamping claw 34. The locking piece 33 can be a locking screw or a screw. During installation, the opening of the tape to be dried is inserted into the clamping cavity, and then the locking piece 33 is locked.

[0051] like Figure 1-Figure 6As shown, the bottom shell 8 is hingedly set on a base 12 on one side of the spiral tape 11, and hinged rods 15 are set on both sides of the bottom shell 8. One end of the hinged rod 15 is hinged to the bottom shell 8 through a first hinge shaft 14, and the other end of the hinged rod 15 is fixedly connected to the two side surfaces of the base 12. The base 12 is located on one side of the hinged rod 15 to form an upwardly protruding connecting support plate 16, and the hinged rod 15 is fixedly connected to the connecting support plate 16. The side of the bottom shell 8 away from the hinged rod 15 is a movable end, and a lifting drive mechanism is set at the movable end.

[0052] The lifting drive mechanism includes a driving cylinder 7, the bottom of which is fixedly mounted on the base 12, a connecting ear 5 is provided on the lower end surface of the bottom shell 8, an articulated bracket 6 is installed on the output end of the driving cylinder 7, and the articulated bracket 6 is hinged to the connecting ear 5 through a second articulated shaft 18, and the angle value of the bottom shell 8 relative to the horizontal plane is controlled by the driving cylinder 7. When the tape is dried normally, the bottom shell 8 is slightly tilted toward one side of the tape to ensure that the position of the counterweight slider 10 remains stationary to achieve better drying. Once winding is required, the driving cylinder 7 is retracted to make the bottom shell 8 tilt in the opposite direction, and the counterweight slider 10 can slide away from the tape, thereby pulling the dried tape to straighten the tape, and the center of the tape is tightened on the winding drum 30. At this time, the driving motor 13 is turned on, and the tape can be wound up under the pulling force of the counterweight slider 10 on the tape. The counterweight of the counterweight slider 10 can be adjusted later and can be selected and replaced according to different tape types, load-bearing capacities, etc.

[0053] In order to improve the sealing performance, the sealing part 2 is made of rubber material, and the sealing part 2 can be connected with the sealing cover 1 by magnetic attraction. The magnetic attraction can be completed by embedding a magnet in the sealing part 2. According to the height of the glue to be dried, the sealing part 2 with different rear ends can be selected. In this way, when the sealing cover 1 is covered with the bottom shell 8, the sealing part 2 can be well sealed and contacted with the top of the adhesive tape to be dried, so that the sealing pressing force is moderate;

[0054] Among them, guide holes are opened at the four corners of the bottom shell 8, and a guide shaft 3 is set at the position corresponding to each guide hole on the lower end surface of the sealing cover 1. The guide shaft 3 is inserted into the guide hole. The sealing cover 1 can be opened relative to the bottom shell 8 manually, or by setting a lifting cylinder on the outside, or by a robot, etc., and any method is available to open the sealing cover 1 vertically relative to the bottom shell 8.

[0055] The present invention provides an efficient and energy-saving adhesive tape drying device, which effectively extends the flow path of the drying gas by arranging the adhesive tape to be dried into a vortex structure and utilizing the structure of the adhesive tape itself to form a single air inlet and a vortex drying channel 100 design, so that the flow path of the drying gas can be fully contacted with the surface of the adhesive tape, and the airflow will not be turbulent, thereby greatly improving the drying efficiency;

[0056] In addition, after the adhesive tape of the present invention is dried, its spiral structure can be used to directly wind it after being straightened by a guide pulling mechanism, and no additional winding equipment and winding stations are needed to wind the adhesive tape, which greatly simplifies the processing steps, improves work efficiency and reduces the production of finished products;

[0057] Finally, since the present invention discharges the drying gas from the middle position of the spiral tape 11, there is only one gas collection port and one gas inlet, so that the entire drying gas can be completely collected after one drying is completed. When the tape is straightened and wound, the pulled tape can be dried a second time, and the interval time during winding can be reasonably utilized for further drying, and the design is more reasonable.

[0058] The above is only a specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope defined in the claims.
