Description

Technical Field

[0001] The invention relates to the technical field of cover tape gluing, in particular to a heat-sealed cover tape gluing device and a process thereof. Background Art

[0002] Heat-sealable cover tape is a sealing material widely used in the food, medicine, cosmetics, electronic packaging and other industries. Its function is to form a sealing film at the mouth of the packaging container to prevent oxidation, deterioration and contamination of the packaging, thereby ensuring the quality and safety of the product. The heat-seal adhesive (adhesive) applied on the heat-sealable cover tape is an important component to achieve this sealing effect. The heat-seal adhesive is usually applied by a coating machine on one side of the tape, and after coating, the solvent in the coating needs to be removed by a drying device to ensure that the coating is dry and uniform. There are two main types of existing coating machines, namely roller transfer coating machines and slot extrusion coating machines. Since there are two main types of heat-sealing adhesives used for heat-sealing cover tapes: emulsion adhesive and acrylic adhesive. Among them, emulsion adhesive is a water-based adhesive, mainly composed of raw materials such as polyacrylic acid emulsion, polyurethane emulsion and acrylate emulsion. It has excellent adhesion and sealing performance, and also has the advantages of heat resistance and chemical resistance. Moreover, because it contains less volatile organic compounds, it has less pollution to the environment during the use of emulsion adhesive, which is more environmentally friendly. However, emulsion adhesive is mostly coated with slot extrusion coating machines. This is because emulsion adhesive is a water-based adhesive with good fluidity. Although roller transfer coating is also a common coating method, it is mainly suitable for slurries with high solid content and high viscosity. Therefore, slot extrusion coating machines are more suitable for emulsion adhesive coating of heat-sealing cover tapes. However, the existing slit extrusion coating machines mostly have fixed slit sizes, which results in certain limitations when coating glues of different thicknesses and cover tapes of different widths. If the coating thickness needs to be changed, it can usually only be achieved indirectly by adjusting the flow rate and pressure of the glue, thereby increasing the complexity of the operation. When the slit of a fixed size is used to coat the narrow cover tape with glue, glue will be wasted in the redundant area, resulting in increased production costs. In view of this, in order to overcome the above technical problems, the present invention proposes a heat-sealed cover tape gluing device and a process thereof, which solves the above technical problems. Summary of the invention

[0003] In order to make up for the shortcomings of the prior art, the present invention proposes a heat-sealing cover tape gluing equipment and a process thereof.

[0011] A heat-sealed cover tape gluing process, which is applicable to the above-mentioned heat-sealed cover tape gluing equipment, has the following steps: S1: Tape winding: first pull one end of the cover tape at the winding mechanism to the tape inlet, and pass it through the tape inlet to wind it above the glue coating cylinder, so that the cover tape passes between the mounting frame and the glue coating cylinder, and is stretched to the winding mechanism; S2: Adjustment of the length of the heat-sealing adhesive: When the electromagnetic piece is powered off, the stepper motor is controlled to drive the screw rod to drive the blocking plate and the blocking sheet to block the extrusion port of the extrusion head to adjust the length of the heat-sealing adhesive extruded by the extrusion head; S3: Heat-sealing adhesive thickness adjustment: When the electromagnetic sheet is energized, the electromagnetic sheet attracts the transmission rod away from the lead screw and enters the rectangular groove, so that the hydraulic oil in the rectangular groove enters the T-slot and pushes the insertion rod out of the T-slot and engages with the belt; the stepper motor drives the worm through the belt to drive the worm wheel to rotate, so that the worm wheel drives the screw to push the adjustment plate to move, so as to adjust the thickness of the heat-sealing adhesive extruded by the extrusion head; S4: Extrusion speed adjustment: first push the L-shaped rod into the circular groove, then rotate the swivel to drive the extrusion head to rotate through the mounting frame, so that the extrusion head is tilted to the set angle; then pull the L-shaped rod out of the circular groove and insert it into the positioning groove on the surface of the swivel; so that the L-shaped rod is clamped and fixed to the swivel; S5: Gluing: After the control is completed, the connecting tube at the upper end of the extrusion head is connected to the external heat-sealing glue delivery pipeline; then the external heat-sealing glue delivery pipeline is controlled to deliver the heat-sealing glue into the extrusion head, so that the heat-sealing glue entering the extrusion head is extruded through the extrusion port and coated on the cover tape wound around the upper end of the glue coating cylinder. At the same time, the external winding mechanism is controlled to wind up the cover tape coated with the heat-sealing glue to obtain the required glue-coated cover tape.

[0012] The beneficial effects of the present invention are as follows: 1. The present invention arranges an adjusting plate and a blocking plate so that the adjusting plate can adjust the width of the extrusion port to change the thickness of the heat-sealing adhesive extruded from the extrusion port; avoids adjusting the flow rate and pressure to affect the uniformity and quality of the coating, and makes the thickness adjustment more accurate and the response faster; and the setting of the blocking plate enables the blocking plate to drive the blocking sheet to block the length direction of the extrusion port, thereby controlling the extrusion length of the heat-sealing adhesive, so that the heat-sealing adhesive can be accurately coated on cover tapes of different widths, avoiding the heat-sealing adhesive being extruded into excess areas and causing waste, thereby reducing production costs; the practicality of the present invention is effectively improved.

[0013] 2. The present invention provides a rotating ring, and the user only needs to rotate the rotating ring to drive the mounting frame to rotate, so that the extrusion head of the mounting frame rotates around the glue coating cylinder, so that the extrusion head is tilted, thereby causing the adjusting plate to tilt downward. When the tilted extrusion head extrude the heat-sealing adhesive, the heat-sealing adhesive will flow along the side of the adjusting plate away from the screw. Since the adjusting plate is tilted, the side of the tilted adjusting plate away from the screw has a certain supporting effect on the heat-sealing adhesive, that is, the gravity of the heat-sealing adhesive will increase the friction between the heat-sealing adhesive and the adjusting plate, thereby reducing the extrusion speed of the heat-sealing adhesive; to prevent the heat-sealing adhesive from being extruded too quickly after the conveying speed of the cover tape is reduced, resulting in an excessive amount of heat-sealing adhesive applied on the surface of the cover tape, thereby facilitating the control of the thickness of the heat-sealing adhesive applied on the surface of the cover tape with a slower extrusion speed, thereby further improving the practical application effect of the present invention.

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0017] like Figures 1 to 8 As shown, the heat-sealing cover tape gluing device of the present invention comprises: The machine body 1 has a rotating rod 11 rotatably connected inside the machine body 1; a glue coating cylinder 111 is fixedly mounted on the surface of the rotating rod 11; a belt inlet 12 is provided on one side of the machine body 1; a mounting frame 13 is provided above the glue coating cylinder 111; the mounting frame 13 is rotatably connected to the machine body 1; an extrusion head 14 is fixedly mounted on one side of the mounting frame 13; an extrusion port 141 is provided at the lower end of the extrusion head 14; a connecting pipe 142 connected to the extrusion port 141 is fixedly mounted on the upper end of the extrusion head 14; An adjusting plate 143 is slidably and sealedly connected to the lower end of the extrusion port 141; a screw 144 is rotatably connected to one side of the adjusting plate 143; the screw 144 is spirally connected to the extrusion head 14; a blocking plate 145 is slidably connected to the lower end of the extrusion port 141; a mounting slot 15 is provided inside the mounting frame 13; a winding rod 151 and a blocking sheet 152 are provided in the mounting slot 15; the winding rod 151 is rotatably connected to the inner wall of the mounting slot 15; one end of the blocking sheet 152 is connected to the winding rod 151, and the other end is connected to the adjusting plate 143; a servo motor 153 is fixedly installed on one side of the extrusion head 14; the servo motor 153 is used to drive the winding rod 151 to rotate; A driving unit is installed at one side of the extrusion port 141 ; the driving unit is used to drive the screw rod 17 to rotate.

[0018] As an embodiment of the present invention, two winding rods 151 are provided; the two winding rods 151 are distributed up and down; the surfaces of the two winding rods 151 are fixedly connected with a spur gear ring 154; the surfaces of the two winding rods 151 are surrounded by a transmission belt 155; the inner wall of the transmission belt 155 is provided with a tooth groove 156 that meshes with the spur gear ring 154; the end of the blocking plate 152 close to the winding rod 151 is fixedly connected to the transmission belt 155.

[0019] As an embodiment of the present invention, the driving unit includes a stepper motor 16; the stepper motor 16 is installed on one side of the extrusion port 141; one side of the adjustment plate 143 is rotatably connected with a screw rod 17; two adjustment plates 143 are provided; the two adjustment plates 143 are distributed at both ends of the screw rod 17; the threads at both ends of the screw rod 17 are arranged oppositely; the screw rod 17 is rotatably connected to the extrusion head 14; the stepper motor 16 is connected to the screw rod 17; When working, the existing slit extrusion coating machines mostly have fixed slit sizes, which leads to certain limitations when coating heat-sealing adhesives of different thicknesses and cover tapes of different widths. If the coating thickness needs to be changed, it can usually only be achieved indirectly by adjusting the flow rate and pressure of the heat-sealing adhesive, thereby increasing the complexity of the operation. When the slit of a fixed size is applied to a narrow cover tape, the heat-sealing adhesive will be wasted in excess areas, resulting in increased production costs. In this regard, the present invention sets the adjustment plate 143 and the blocking plate 145 so that the adjustment plate 143 can adjust the width of the extrusion port 141 to change the thickness of the heat-sealing adhesive extruded from the extrusion port 141; avoid adjusting the flow rate and pressure to affect the uniformity and quality of coating, so that the thickness adjustment is more accurate and the response is faster; and the setting of the blocking plate 145 enables the blocking plate 145 to drive the blocking sheet 152 to block the length direction of the extrusion port 141, thereby controlling the extrusion length of the heat-sealing adhesive, so that the heat-sealing adhesive can be accurately coated on cover tapes of different widths, avoiding the heat-sealing adhesive being extruded in excess areas and causing waste, thereby reducing production costs; so that the practicality of the present invention is effectively improved; In the initial state, the cover tape is placed on the winding mechanism, and the extrusion head 14 is connected to the external heat-sealing adhesive delivery pipeline through the connecting pipe 142 at the upper end; the user stretches one end of the cover tape on the winding mechanism to make it pass through the tape inlet 12, so that the cover tape passes from the bottom of the glue coating cylinder 111, so that the cover tape is wound around the top of the glue coating cylinder 111 from the side of the glue coating cylinder 111 away from the tape inlet 12, and then the end of the cover tape wound around the top of the glue coating cylinder 111 is pulled to the winding mechanism for winding operation; when the cover tape is pulled to the winding mechanism, the user can directly control the external heat-sealing adhesive delivery pipeline to deliver the heat-sealing adhesive through the connecting pipe 14 2 enters the extrusion head 14, so that the heat-sealing glue filled in the extrusion head 14 can be squeezed out through the extrusion port 141, so that the heat-sealing glue in the extrusion port 141 can flow downward along the side of the adjustment plate 143 away from the screw 144; because the extrusion head 14 is located above the glue coating cylinder 111, the heat-sealing glue extruded from the extrusion head 14 can flow downward to the upper end of the cover tape wound around the glue coating cylinder 111, so that the heat-sealing glue extruded from the extrusion head 14 can be coated on the upper end of the cover tape, and at the same time, the winding mechanism is controlled to continuously wind the cover tape, so that the heat-sealing glue extruded from the extrusion head 14 can be evenly coated on the upper end of the cover tape; Since the viscosity of the cover tape is affected by the coating thickness of the heat-sealing adhesive, that is, the greater the coating thickness of the heat-sealing adhesive, the higher the viscosity of the cover tape; and different application occasions have different requirements for the viscosity of the cover tape; for example, for some products with higher sealing requirements, a cover tape with high viscosity is required, while for light packaging, a cover tape with low viscosity can be used; when it is necessary to produce a cover tape with low viscosity, the user needs to first rotate the screw rod 144 so that the screw rod 144 rotates relative to the adjustment plate 143, so that the screw rod 144 rotating relative to the adjustment plate 143 can spirally rotate and enter the extrusion port 141, so that the extrusion The adjusting plate 143 in the pressing port 141 is pushed by the screw 144 to continuously move toward the side of the extrusion port 141 close to the connecting tube 142, so that the distance between the side of the adjusting plate 143 away from the screw 144 and the side of the extrusion port 141 close to the connecting tube 142 is reduced, and then when the heat-sealing adhesive in the extrusion port 141 flows downwardly through the side of the adjusting plate 143 away from the screw 144 and the side of the extrusion port 141 close to the connecting tube 142, the thickness of the flowing heat-sealing adhesive is reduced, so that the thickness of the heat-sealing adhesive coated on the upper end of the cover tape is reduced, thereby achieving the production of a cover tape with less viscosity; Since the market demand for products may change at any time, manufacturers often need to adjust the width of the cover tape according to customer needs; when the width of the cover tape is reduced, the user needs to control the stepper motor 16 to operate so that the stepper motor 16 drives the screw rod 17 to rotate; since the threads at both ends of the screw rod 17 are arranged in opposite directions, and the two blocking plates 145 are spirally connected to the two ends of the screw rod 17, the screw rod 17 can drive the two blocking plates 145 connected to the screw rod 17 to approach each other, so that the blocking plate 145 pulls the blocking sheet 152 in the installation slot 15 out of the installation slot 15, so that the blocking sheet 152 extending out of the installation slot 15 The sheet 152 can partially block the two ends of the extrusion port 141 until the distance between the two blocking plates 145 just matches the width of the cover tape, and then the stepper motor 16 is controlled to stop rotating. At the same time, the servo motor 153 is controlled to run, so that the servo motor 153 can drive the winding rod 151 to rotate, so that the collection rod pushes the tooth groove 156 of the inner ring wall of the transmission belt 155 through the spur gear ring 154 to drive the transmission belt 155 to rotate around the two collection rods, so that the transmission belt 155 can drive the blocking sheet 152 fixed thereto to be wound up. Since the stepper motor 16 has a self-locking ability; that is, when the stepper motor 16 is When the motor 16 stops receiving input pulses and keeps the winding energized, the motor can keep a fixed position, so that the stepper motor 16 has a self-locking ability; therefore, when the blocking sheet 152 is pulled by the transmission belt 155 and enters the installation groove 15, the end of the blocking sheet 152 away from the installation groove 15 will generate a pulling force on the blocking plate 145, but because the blocking plate 145 is driven by the screw rod 17 and the stepper motor 16 connected to the screw rod 17 is self-locking, the blocking plate 145 cannot move, that is, the blocking sheet 152 is in a tightened state at this time; thereby ensuring that the tightened blocking sheet 152 can fit tightly with the extrusion port 141, Thereby, the blocking sheet 152 can effectively block the local positions at both ends of the extrusion port 141, and effectively prevent the heat-sealing adhesive extruded from the extrusion port 141 from flowing out through the gap between the blocking sheet 152 and the lower end of the extrusion head 14; ensure that the heat-sealing adhesive extruded from the extrusion port 141 can flow out through the gap between the two blocking plates 145, so that the length of the extruded heat-sealing adhesive is not only the distance between the two blocking plates 145, but also the width of the cover tape, so that the extruded heat-sealing adhesive can be accurately coated on the cover tape to prevent the extruded heat-sealing adhesive from exceeding the cover tape and causing waste, thereby reducing production costs and improving the practicability of the present invention.

[0020] As an embodiment of the present invention, a worm 171 is arranged above the screw 17; a mounting shell 18 fixedly connected to the extrusion head 14 is arranged on the side of the worm 171 away from the extrusion head 14; the worm 171 and the screw 17 are both rotatably connected to the mounting shell 18; a worm wheel 172 is fixedly connected to the end of the screw 144 away from the adjustment plate 143; the worm wheel 172 is meshed with the worm 171; a transmission unit is installed between the mounting shell 18 and the extrusion head 14; the stepping motor 16 drives the worm 171 to rotate through the transmission unit.

[0021] As an embodiment of the present invention, the transmission unit includes a transmission rod 162; the output shaft of the stepper motor 16 is provided with a rectangular groove 161; the transmission rod 162 is slidingly sealed and connected in the rectangular groove 161; the transmission rod 162 is connected to the bottom of the rectangular groove 161 through a connecting spring 163; the bottom of the rectangular groove 161 is inlaid with an electromagnetic sheet 164; the output shaft of the stepper motor 16 and the worm 171 are connected by a belt drive through a belt 181; and a slot is provided at one end of the lead screw 17 close to the stepper motor 16.

[0022] As an embodiment of the present invention, the transmission unit further includes an insertion rod 165; the output shaft of the stepper motor 16 is provided with a T-shaped slot 166 connected to the rectangular slot 161; the insertion rod 165 is slidably sealed and connected in the T-shaped slot 166; the inner ring wall of the belt 181 is provided with a slot 182 that matches the insertion rod 165; the surface of the worm 171 is fixedly connected with a protrusion 173 that matches the slot 182; When working, in the initial state, the belt 181 is made of PTFE material, and the electromagnetic sheet 164 is in the power-off state, so that the transmission rod 162 extends out of the rectangular groove 161 and is inserted into the slot under the push of the connecting spring 163; at this time, as the stepper motor 16 runs, the stepper motor 16 can drive the screw rod 17 to rotate through the transmission rod 162, so that the screw rod 17 can drive the two blocking plates 145 to pull the blocking plates 152 to move towards each other; thereby adjusting the length of the extruded heat-sealing glue; when it is necessary to adjust the adjustment plate 143, it is only necessary to control the electromagnetic sheet 164 to be energized so that the electromagnetic sheet 164 can produce magnetic adsorption on the transmission rod 162. The force causes the transmission rod 162 to squeeze the connecting spring 163 into the rectangular groove 161 under the adsorption of the electromagnetic sheet 164, so that the transmission rod 162 can extend out of the slot and away from the screw rod 17; the transmission rod 162 is separated from the screw rod 17. Since the rectangular groove 161 is filled with hydraulic oil, and the T-slot 166 is connected to the rectangular groove 161, the transmission rod 162 adsorbed by the electromagnetic sheet 164 can squeeze the hydraulic oil in the rectangular groove 161 during the process of entering the rectangular groove 161, so that the hydraulic oil in the rectangular groove 161 flows into the T-slot 166, so that the hydraulic oil flowing into the T-slot 166 can push the insertion rod 16 in the T-slot 166. 5 extends out of the T-slot 166, so that the insertion rod 165 extending out of the T-slot 166 can be inserted into the slot 182 directly opposite to it; at this time, as the stepper motor 16 runs, the stepper motor 16 can push the slot wall of the slot 182 through the T-rod to drive the entire belt 181 to rotate; because the worm 171 is meshed with the slot 182 on the inner wall of the belt 181 through the protrusion 173 fixed on the surface; during the rotation of the belt 181, the belt 181 can drive the worm 171 to rotate through the protrusion 173 fixed on the surface of the worm 171, so that the worm 171 can drive the worm wheel 172 meshed with it to rotate during the rotation, so that the worm wheel 172 can drive the worm wheel 172 to rotate. The fixed screw 144 rotates, so that the rotating screw 144 is spirally mixed into the extrusion head 14, so that the screw 144 pushes the adjustment plate 143 to adjust the thickness of the heat-sealing adhesive extruded from the extrusion port 141; compared with manually rotating the screw 144, the transmission method of the worm gear 172 and the worm 171 is not only more accurate and fast, but also the worm gear 172 and the worm 171 have a self-locking mechanism, which can prevent the heat-sealing adhesive in the extrusion port 141 from being pushed by the adjustment plate 143 to move and drive the screw 144 to move, thereby ensuring that the adjustment plate 143 can stably adjust the width of the extrusion port 141; so that the practical application effect of the present invention is further improved;The installation shell 18 is used to shield the worm wheel 172 and the worm 171 to prevent foreign impurities or heat-sealing adhesive from splashing onto the worm wheel 172 and the worm 171. It not only prevents the worm wheel 172 and the worm 171 from being blocked by foreign impurities or splashing heat-sealing adhesive, thereby reducing the transmission effect of the worm wheel 172 and the worm 171, but also reduces the adhesion and wear of foreign impurities on the worm wheel 172 and the worm 171, thereby increasing the service life of the worm wheel 172 and the worm 171.

[0023] As an embodiment of the present invention, the surface of the rotating rod 11 is sleeved with two rotating rings 2; the two rotating rings 2 are distributed on both sides of the glue coating cylinder 111; one end of the rotating ring 2 is rotatably connected to the body 1; the other end is connected to the mounting frame 13; a positioning groove 21 is provided on the outer ring wall of the rotating ring 2; a circular groove 22 is provided on one side of the body 1 close to the rotating ring 2; an L-shaped rod 23 is slidably connected in the circular groove 22; the L-shaped rod 23 is connected to the bottom of the circular groove 22 by a fixing spring 231; During operation, the extrusion speed of the heat-sealing adhesive extruded by the extrusion head 14 is not only affected by its own fluidity, but also easily affected by gravity and the friction between the inner wall of the extrusion port 141 and the inner wall of the adjustment plate 143. If the extrusion head 14 is vertically downward, the heat-sealing adhesive extruded by the extrusion head 14 is most affected by gravity and the friction between the inner wall of the extrusion port 141 and the inner wall of the adjustment plate 143, that is, the heat-sealing adhesive extrusion speed is the fastest. Therefore, the external winding mechanism needs to quickly convey the cover tape for coating the heat-sealing adhesive. However, the faster the conveying speed of the cover tape, the greater the friction between the cover tape and the glue coating cylinder 111. Especially for a thinner cover tape, if the friction is too large, it will cause the thinner cover tape to be damaged. Therefore, when coating the thinner cover tape with heat When sealing the glue, it is necessary to slow down the conveying speed of the cover tape. To this end, the present invention provides a rotating ring 2. The user only needs to rotate the rotating ring 2 to make the rotating ring 2 drive the mounting frame 13 to rotate, so that the extrusion head 14 hit by the mounting frame 13 rotates around the glue coating cylinder 111, so that the extrusion head 14 is tilted, thereby making the adjustment plate 143 tilt downward. When the tilted extrusion head 14 extrude the heat-sealing glue, the heat-sealing glue will flow along the side of the adjustment plate 143 away from the screw 144. Because the adjustment plate 143 is tilted, the side of the tilted adjustment plate 143 away from the screw 144 has a certain supporting effect on the heat-sealing glue, that is, the gravity of the heat-sealing glue will increase the friction between the heat-sealing glue and the adjustment plate 143, thereby reducing the extrusion speed of the heat-sealing glue; in order to prevent the cover tape from being conveyed at a high speed, After the degree is reduced, the extrusion speed of the heat-sealing adhesive is too fast, resulting in an excessive amount of heat-sealing adhesive applied to the surface of the cover tape, thereby facilitating the control of the thickness of the heat-sealing adhesive applied to the surface of the cover tape with a slower extrusion speed, thereby further improving the practical application effect of the present invention; and the L-shaped rod 23 is provided for fixing the swivel 2. Because when the swivel 2 drives the mounting frame 13 to rotate, the mounting frame 13 tilts, causing the center of gravity of the swivel 2 to shift. In order to ensure that the mounting frame 13 does not deflect downward due to the unstable center of gravity, the L-shaped rod 23 is provided so that the L-shaped rod 23 can be inserted into the positioning groove 21 on the surface of the swivel 2, thereby fixing the swivel 2, so as to ensure that the mounting frame 13 drives the extrusion head 14 to extrude the heat-sealing adhesive stably and tiltedly; That is, before rotating the swivel 2, the user first rotates the L-shaped rod 23 so that the protruding end of the L-shaped rod 23 rotates in the direction away from the swivel 2 until the protruding end of the L-shaped rod 23 is away from the swivel 2, and then pushes the L-shaped rod 23 to squeeze the fixing spring 231 into the circular groove 22. At this time, the L-shaped rod 23 is located between the swivel 2 and the body 1. After rotating the swivel 2 to the desired position, the positioning groove 21 on the surface of the swivel 2 is opposite to the circular groove 22. The L-shaped rod 23 is loosened, so that the L-shaped rod 23 extends out of the circular groove 22 and is inserted into the positioning groove 21 under the push of the restoring force of the fixing spring 231. Rotating the L-shaped rod 23 again causes the protruding end of the L-shaped rod 23 to rotate toward the center of the swivel 2, so that the L-shaped rod 23 is clamped to the swivel 2; thereby achieving the fixation of the swivel 2.

[0024] A heat-sealed cover tape gluing process, which is applicable to the above-mentioned heat-sealed cover tape gluing equipment, has the following steps: S1: Tape winding: first pull one end of the cover tape at the winding mechanism to the tape inlet 12, and pass it through the tape inlet 12 to be wound above the glue coating cylinder 111, so that the cover tape passes between the mounting frame 13 and the glue coating cylinder 111, and is stretched to the winding mechanism; S2: Adjustment of the length of the heat-sealing adhesive: When the electromagnetic sheet 164 is powered off, the stepping motor 16 is controlled to drive the screw rod 17 to drive the blocking plate 145 and the blocking sheet 152 to block the extrusion port 141 of the extrusion head 14, so as to adjust the length of the heat-sealing adhesive extruded by the extrusion head 14; S3: Heat-sealing adhesive thickness adjustment: When the electromagnetic sheet 164 is energized, the electromagnetic sheet 164 attracts the transmission rod 162 away from the screw rod 17 and enters the rectangular groove 161, so that the hydraulic oil in the rectangular groove 161 enters the T-slot 166 and pushes the insertion rod 165 to extend out of the T-slot 166 and engage with the belt 181; the stepping motor 16 drives the worm 171 through the belt 181 to drive the worm wheel 172 to rotate, so that the worm wheel 172 drives the screw rod 144 to push the adjustment plate 143 to move, so as to adjust the thickness of the heat-sealing adhesive extruded by the extrusion head 14; S4: Extrusion speed adjustment: first push the L-shaped rod 23 into the circular groove 22, then rotate the swivel 2 to drive the extrusion head 14 to rotate through the mounting frame 13, so that the extrusion head 14 is tilted to a set angle; then pull the L-shaped rod 23 out of the circular groove 22 and insert it into the positioning groove 21 on the surface of the swivel 2; so that the L-shaped rod 23 is clamped and fixed to the swivel 2; S5: Glue coating: After the control is completed, the connecting tube 142 at the upper end of the extrusion head 14 is connected to the external heat-sealing glue delivery pipeline; then the external heat-sealing glue delivery pipeline is controlled to deliver the heat-sealing glue into the extrusion head 14, so that the heat-sealing glue entering the extrusion head 14 is extruded through the extrusion port 141 and coated on the cover tape wound on the upper end of the glue coating cylinder 111. At the same time, the external winding mechanism is controlled to wind up the cover tape coated with the heat-sealing glue to obtain the required glue-coated cover tape.
