Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] refer to Figure 1 A production equipment for hot melt double-sided adhesive tape, wherein the equipment box 1 is used to house components such as a pressure pump 15, a connecting pipe 16 and an output outlet 17, and a support platform 2 is provided at the top of the equipment box 1, which is used to support other components for producing hot melt double-sided adhesive tape.

[0023] refer to Figure 1The hot melt double-sided tape is produced on the operating table 3, which is located on top of the support platform 2. The operating table 3 is detachable and can be removed for cleaning and maintenance. Four sets of glue-applying rods 10 are arranged around the top edge of the operating table 3. The rotating rod 12 is driven by the motor 11 to rotate, which in turn drives the winding rod 13 to rotate, so that the hot melt double-sided tape is wound on the winding rod 13. There are two glue-applying rods 10 in each set, and there is a gap between the two glue-applying rods 10. At this time, the hot melt double-sided tape passes through the glue-applying rods 10, and both sides of the hot melt double-sided tape are coated with glue. The four sets of glue-applying rods 10 can produce four rolls of hot melt double-sided tape at the same time.

[0024] refer to Figure 1 Each of the four sets of glue-applying rods 10 has a limiting block 9 on one side. There are two limiting blocks 9 in each set, and there is a gap between the two limiting blocks 9. The hot melt double-sided adhesive passes through the limiting block 9 and then passes through the glue-applying rod 10 to be pre-wound onto the winding rod 13. The winding rod 13 rotates and drives the hot melt double-sided adhesive to be wound onto the winding rod 13. At this time, the limiting block 9 can continuously limit the hot melt double-sided adhesive.

[0025] refer to Figure 1 Two glue-applying rods 10 are provided on one side opposite to the two limiting blocks 9. Hot melt double-sided adhesive is applied manually by passing it through the glue-applying rods 10. The applied hot melt double-sided adhesive is sticky. The hot melt double-sided adhesive is then stuck onto the winding rod 13. The winding rod 13 has a concave arc-shaped groove. The arc-shaped groove is used to gather and limit the hot melt double-sided adhesive, so that the hot melt double-sided adhesive is wound into the groove 19 on the winding rod 13. At this time, the concave arc-shaped groove on the winding rod 13 can continuously limit the hot melt double-sided adhesive.

[0026] refer to Figure 1 Multiple sets of glue-applying rods 10 can simultaneously produce multiple rolls of double-sided tape, resulting in high work efficiency. The hot melt double-sided tape is limited by the limiting block 9, and the double-sided tape is effectively limited by the concave arc groove on the winding rod 13. The double-sided tape is not easy to fall off during the production process, making it highly practical.

[0027] refer to Figure 1 The top surface of the limiting block 9 is at the same height as the top surface of the glue applicator 10, which facilitates the limiting of the hot melt double-sided adhesive. The same height allows the hot melt double-sided adhesive to be stably positioned on the same horizontal plane when passing through the limiting block 9 for glue application, which can improve the stability of the production process. The bottom end of the limiting block 9 is fixedly connected to the support platform 2, which can improve the stability of the limiting block 9. The limiting block 9 is not easy to fall off due to long-term work.

[0028] refer to Figure 1The top surface of the winding rod 13 is at the same height as the top surface of the adhesive applicator 10, which facilitates the winding of the hot melt double-sided adhesive. The same height allows the hot melt double-sided adhesive to be rolled stably on the same horizontal plane after the adhesive is applied, which can improve the stability of the production process. The bottom end of the winding rod 13 is rotatably connected to the support platform 2, which does not affect the rotation of the winding rod 13 to wind the hot melt double-sided adhesive, and also improves the stability of the winding rod 13.

[0029] refer to Figure 1 The top of the support platform 2 is located on one side of the operating platform 3 and is set on the control panel 4. The control panel 4 is equipped with multiple control buttons. Users can control the operation of the equipment by operating the control buttons on the control panel 4. The control panel 4 is connected to an external control box via wires. The external control box can be a PLC control box. A PLC control box refers to a programmable control cabinet, which is an electrical cabinet that can control the motor 11 and the switch through pre-programming.

[0030] refer to Figure 1 The top of the limiting block 9 is provided with a connecting mechanism 8, which is used to connect the limiting block 9 and the fixing plate 7, thereby improving the stability of the limiting block 9 and preventing the hot melt double-sided adhesive from damaging the limiting block 9 during the production process. The top of the connecting mechanism 8 is fixedly connected to the fixing plate 7, which is used to fix the connecting mechanism 8 and the rotating rod 12 and other components.

[0031] refer to Figure 1 The connecting mechanism 8 includes a support plate connecting two limiting blocks 9 and a support rod connecting a fixed plate 7. The support plate is used to connect the limiting blocks 9, and the support rod is used to connect the support plate and the fixed plate 7. The top of the fixed plate 7 is provided with a connecting plate 6, which is used to connect with the support mechanism 5. The bottom of the connecting plate 6 is fixedly connected to the support mechanism 5. The support mechanism 5 is used to connect the connecting plate 6 and the bearing platform 2. The bottom of the support mechanism 5 is fixedly connected to the bearing platform 2, thereby improving stability.

[0032] refer to Figure 1 The support mechanism 5, connecting plate 6, fixing plate 7 and connecting mechanism 8 are all provided in four sets. The support mechanism 5, connecting plate 6, fixing plate 7 and connecting mechanism 8 are all centrally symmetrically arranged with the operating table 3 as the center, which can facilitate multiple users to carry out the production of hot melt double-sided adhesive at the same time and improve the production efficiency of hot melt double-sided adhesive.

[0033] refer to Figure 1A rotating rod 12 is fixedly connected to the top of the glue applicator. A motor 11 is provided on one side of the top of the fixed plate 7. The motor 11 is rotatably connected to the rotating rod 12. The rotating rod 12 is driven by the motor 11 to rotate, and the winding rod 13 connected to the bottom of the rotating rod 12 is rotated simultaneously to realize the winding of hot melt double-sided adhesive. There are four sets of rotating rods 12 and motors 11, which can facilitate multiple users to carry out the production of hot melt double-sided adhesive at the same time and improve the production efficiency of hot melt double-sided adhesive.

[0034] refer to Figure 2 The equipment box 1 has a back plate 14 on the back. The back plate 14 is detachable. The components inside the equipment box 1 can be repaired and cleaned by removing the back plate 14. The back plate 14 has multiple rectangular through slots, which can be used for heat dissipation to prevent the components inside the equipment box 1 from being damaged by the heat generated during long-term use.

[0035] refer to Figure 3 The equipment box 1 is equipped with a pressure pump 15, which is existing technology. The specific working principle is as follows: first, the pressure pump 15 is filled with glue liquid, and then the centrifugal pump is started. The impeller rotates rapidly, and the blades of the impeller drive the liquid to rotate. When the liquid rotates, it flows to the outer edge of the impeller by inertia. At the same time, the impeller draws liquid in from the suction chamber. During this process, the liquid in the impeller flows around the blades. In the flow motion, the liquid exerts a lift force on the blades. Conversely, the blades exert a force on the liquid with a force equal in magnitude and opposite in direction to this lift force. This force does work on the liquid, so that the liquid gains energy and flows out of the impeller. At this time, the kinetic energy and pressure energy of the liquid both increase.

[0036] refer to Figure 3 The pressure pump 15 is equipped with a connecting pipe 16 at its top. The pressure pump 15 is filled with adhesive for applying hot melt double-sided tape. The pressure pump 15 pressurizes the adhesive into the connecting pipe 16. The connecting pipe 16 is equipped with an output outlet 17 at its top. The adhesive in the connecting pipe 16 is transported to the output outlet 17 by the pressure pump 15. The top of the output outlet 17 passes through the equipment box 1 and the operating table 3 and is connected to the coating rod. The adhesive is transported to the coating rod 10 through the output outlet 17. The coating rod 10 may have small holes to allow the adhesive to penetrate to the surface of the coating rod 10, thereby achieving the coating effect.

[0037] refer to Figure 4 The equipment box 1 has four support blocks 18 at the top corners. The support blocks 18 are used to support the equipment box 1 and other components. The support blocks 18 can be made of rough rubber material, which can increase friction and improve stability. The equipment box 1 has grooves 19 on both sides at the bottom. The cross-section of the grooves 19 is semi-circular. Users can put their hands into the grooves 19 to effectively leverage the force, which makes it easy to move the entire production equipment.
