Description

Technical Field

[0001] The invention relates to the technical field of production of degradable adhesive tapes, in particular to a gluing device and a gluing method for production of degradable adhesive tapes. Background Art

[0002] With the improvement of environmental awareness, degradable materials are being used more and more widely in the packaging industry. As an environmentally friendly product, degradable tape has high requirements on the uniformity of glue coating, the environmental performance of glue and production efficiency during its production process. During the production process of degradable tape, it is necessary to coat the degradable tape with glue to achieve the stickiness of the tape.

[0003] The Chinese patent proposes a gluing device and production equipment for the production of degradable tape, with the publication number CN113102169A, which includes a mounting seat and two sets of traction rollers mounted on both sides of the mounting seat. The traction rollers are connected to a power mechanism for driving the traction rollers to rotate. A spraying mechanism for spraying glue on the tape and a spreading mechanism for evenly spreading the glue on the surface of the tape are provided between the traction rollers.

[0004] The glue coating device in the above scheme can improve the efficiency of glue spraying, and at the same time facilitate the adjustment of the longitudinal stroke range of the spraying pipe, and can make the glue evenly spread on the tape, but there are still the following problems:

[0005] The tape is easily exposed to dust during transmission. If the dust is not cleaned in time, it is easy to cause the dusty area to fail to be coated with glue, which leads to uneven glue coating of the tape.

[0006] The tape is prone to wrinkles during transportation and gluing. The presence of wrinkles is not only not conducive to evenly spraying the glue on the tape surface, but also has an adverse effect on the subsequent winding operation.

[0007] Therefore, the design is practical and the dust attached to the degradable tape is wiped off by the dust removal cloth arranged in the dust removal box. The reciprocating screw rotates to drive the friction block to move back and forth. The friction block continuously rubs against the bottom end surface of the plastic plate to generate static electricity on the plastic plate. The dust particles remaining on the coating surface of the degradable tape can be adsorbed onto the plastic plate under the action of static electricity, effectively avoiding the problem of uneven coating of the coating surface of the degradable tape due to the attachment of dust. At the same time, the two moving plates perform intermittent reciprocating motion, so that the smoothing rod on the moving plate can move back and forth intermittently along the width direction of the degradable tape, so that the degradable tape can be stretched and smoothed, and the upper end surface of the degradable tape can be further flattened with the flattening rod, which effectively prevents the degradable tape from wrinkling during transmission, affecting the gluing effect and the subsequent winding work. A gluing device and a gluing method for the production of degradable tape are very necessary. Summary of the invention

[0018] Based on the above-mentioned gluing device for producing a degradable adhesive tape, the present invention also provides a gluing method for producing a degradable adhesive tape, comprising the following steps:

[0019] Step 1: Place the tape roll on the first mounting frame, then pass the degradable tape between the transmission roller and the guide roller on the second mounting frame and the fourth mounting frame, and extend to the outer end of the fourth mounting frame, and finally wind it on the winding device, and then adjust the tightness of the degradable tape during transmission by turning the hand wheel;

[0020] Step 2: Start the driving motor to start the transmission of the degradable tape. When the degradable tape passes through the second mounting rack, the dust removal cloth can wipe off the dust attached to the degradable tape, and the dust collection box can electrostatically adsorb the dust particles remaining on the degradable tape onto the plastic plate, thereby achieving dust removal of the degradable tape;

[0021] Step 3: When the degradable tape passes between the second mounting frame and the third mounting frame, the smoothing rods on the two movable plates can stretch and smooth the degradable tape along the width direction of the degradable tape, and cooperate with the flattening rod to further flatten the upper end surface of the degradable tape to avoid wrinkles on the degradable tape;

[0022] Step 4: When the degradable tape is transferred to the third mounting frame, multiple glue spray heads in the glue spray box spray glue, and the brushing plate brushes the glue on the degradable tape so that the glue is evenly brushed on the glue-coated surface of the degradable tape;

[0023] Step 5: The glue-coated degradable tape can then be heated and dried in a drying box to quickly solidify the glue on the degradable tape. Finally, the degradable tape is transmitted through the fourth mounting rack and rolled up, completing the gluing of the degradable tape.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. The present invention can wipe off the dust attached to the degradable tape through the dust removal cloth arranged in the dust removal box. When the transmission roller in the second mounting frame rotates, the reciprocating screw rotates to drive the friction block to move back and forth. The friction block will continue to rub against the bottom end surface of the plastic plate when moving, thereby generating static electricity on the plastic plate. The dust particles remaining on the coating surface of the degradable tape can be adsorbed onto the plastic plate under the action of static electricity, effectively avoiding the problem of uneven coating of the coating surface of the degradable tape due to the adhesion of dust. In addition, the plastic plate can be quickly disassembled after the coating operation is completed, which is convenient for cleaning the dust adsorbed on the plastic plate and convenient for subsequent use.

[0026] 2. According to the present invention, when the reciprocating screw rotates, the first worm gear meshing with the first worm gear can be driven to rotate, so that the first rotating rod drives the half gear to rotate. When the half gear rotates, the two movable plates can perform intermittent reciprocating motion. The smoothing rod on the movable plate can intermittently move back and forth along the width direction of the degradable tape, so that the degradable tape can be stretched and smoothed. At the same time, the friction block can drive the flattening rod to move when it reciprocates, so as to further flatten the upper end surface of the degradable tape, thereby effectively preventing the degradable tape from wrinkling during transmission, affecting the gluing effect and the subsequent winding work.

[0027] 3. In the present invention, the first worm gear can drive the second rotating rod to drive the crank to rotate when rotating, and the sliding column on the crank can slide in the arc frame, so that the arc frame drives the piston to move back and forth in the cylinder, so that the glue in the glue box can be continuously pumped into the glue spray box, and the glue is sprayed out through multiple glue spray heads after diversion in the glue spray box. After the glue is sprayed onto the degradable tape, it will be brushed by the brushing plate. The brushing plate can be tightly attached to the glue coating surface of the degradable tape under the elastic potential energy of the tension spring, ensuring that the glue can be evenly brushed on the glue coating surface of the degradable tape, thereby improving the glue coating effect.

[0028] 4. In the present invention, the transmission roller in the fourth mounting frame can rotate through the second worm gear, so that the multiple third rotating rods on the fixed support plate in the drying box rotate, and the third rotating rods drive the fan blades to rotate, and cooperate with the electric heating wire to heat the inhaled air and blow it downward. The setting of the dustproof net can prevent external dust from being inhaled into the drying box, thereby drying the sprayed degradable tape, allowing the glue to solidify quickly, and further improving the gluing efficiency of the degradable tape.

A suspension rod is fixedly arranged on the spray box 932, and the suspension rod is fixedly arranged in the third mounting frame 6. A second rotating rod 9311 is rotatably connected to the bottom plate 922, and a second worm gear 9312 meshing with the first worm gear 924 is fixedly sleeved on the second rotating rod 9311. A crank 9313 is fixedly arranged on the second rotating rod 9311, and a sliding column 9314 is fixedly arranged on the crank 9313. The sliding column 9314 is slidably connected to the inner wall of the arc frame 9310. A limiting plate 9318 is fixedly arranged on the sliding rod 9317, and a tension spring 9319 is fixedly arranged between the limiting plate 9318 and the connecting plate 9315.

[0058] Specifically, when the first worm gear 924 rotates, it can drive the second rotating rod 9311 to drive the crank 9313 to rotate. The sliding column 9314 on the crank 9313 can slide in the arc frame 9310, so that the arc frame 9310 drives the piston 938 to move back and forth in the cylinder 935, so that the glue in the glue box 931 can be continuously pumped into the glue spray box 932. After being diverted in the glue spray box 932, the glue is sprayed out through multiple glue spray heads 933. After being sprayed onto the degradable tape 4, the glue will be brushed by the brushing plate 9316. The brushing plate 9316 can be tightly attached to the glue coating surface of the degradable tape 4 under the elastic potential energy of the tension spring 9319, ensuring that the glue can be evenly brushed on the glue coating surface of the degradable tape 4, thereby improving the glue coating effect.

[0059] See also Fig.15 and Fig.16 , it is further obtained that the gluing mechanism 9 also includes a drying section 94, which includes a drying box 941, a second worm 943 is rotatably connected in the drying box 941, a fixed support plate 945 is fixedly arranged in the drying box 941, a plurality of third rotating rods 946 are rotatably connected on the fixed support plate 945, a third worm wheel 948 meshingly connected with the second worm 943 is fixedly arranged on the third rotating rod 946, a fan blade 947 is fixedly arranged on the lower end surface of the third rotating rod 946, and a heating wire 949 is arranged below the fan blade 947; the drying box 941 is fixedly arranged on the third mounting frame 6, one end of the second worm 943 rotatably penetrates the drying box 941, and a third belt transmission group 944 is arranged between the output shaft of the transmission roller 81 in the fourth mounting frame 7, a dustproof net 942 is arranged above the fixed support plate 945, the dustproof net 942 is fixedly arranged in the drying box 941, and the heating wire 949 is fixedly connected to the inner wall of the drying box 941.

[0060] Specifically, the second worm gear 943 can rotate the transmission roller 81 in the fourth mounting frame 7, so that the multiple third rotating rods 946 on the fixed support plate 945 in the drying box 941 can rotate, and the third rotating rods 946 drive the fan blades 947 to rotate, and cooperate with the heating wire 949 to heat the inhaled air and blow it downward. The setting of the dustproof net 942 can prevent external dust from being sucked into the drying box 941, thereby drying the sprayed degradable tape 4, allowing the glue to solidify quickly, thereby improving the gluing efficiency of the degradable tape 4.

[0061] In the actual operation process: first, the tape roll 3 is placed on the first mounting frame 2, and then the degradable tape 4 is passed between the transmission roller 81 and the guide roller 85 on the second mounting frame 5 and the fourth mounting frame 7, and extended to the outer end of the fourth mounting frame 7 and wound on the winding device, and then the screw rod 87 is rotated by turning the hand wheel 88, and the lifting frame 84 drives the guide roller 85 to move up and down under the action of the threaded connection, so as to adjust the distance between the guide roller 85 and the transmission roller 85, and then the tightness of the degradable tape 4 during transmission can be adjusted to ensure the normal transmission of the degradable tape 4, and then the gluing operation can be started;

[0062] When gluing the degradable tape 4, start the driving motor 83 to make the two groups of transmission rollers 81 transmit the degradable tape 4. When the degradable tape 4 is transmitted to the dust removal box 912 on the second mounting frame 5, the dust removal cloth 913 arranged in the dust removal box 912 can wipe off the dust attached to the degradable tape 4. When the transmission roller 81 in the second mounting frame 5 rotates, the transmission shaft 914 can rotate under the transmission of the first belt transmission group 915, and then under the meshing transmission of the gear transmission group 917, the reciprocating screw rod 916 starts to rotate. The limiting slider 9116 threadedly connected to the reciprocating screw rod 916 can drive the friction block 9115 to reciprocate under the action of the thread. The limiting rod 9117 can provide stability and guidance for the movement of the friction block 9115. When moving, 9115 will continue to rub against the bottom end surface of the plastic plate 919, thereby generating static electricity on the plastic plate 919. When the degradable tape 4 is transmitted to the bottom of the dust collection box 918, the dust particles remaining on the glue-coated surface of the degradable tape 4 can be adsorbed onto the plastic plate 919 under the action of static electricity, effectively avoiding the problem of uneven glue coating on the glue-coated surface of the degradable tape 4 due to the adhesion of dust. After the glue coating operation is completed, the pressing plate 9113 can be released from the tight fixation of the plastic plate 919 by pulling the lifting handle on the guide rod 9112, and then the pressing plate 9113 can be rotated to the end away from the plastic plate 919, and then the plastic plate 919 can be removed by the handle on the plastic plate 919, and the dust adsorbed on the plastic plate 919 can be cleaned for subsequent use;

[0063] When the transmission shaft 914 is rotating, the first worm 924 can rotate under the transmission action of the second belt transmission group 925. When the first worm 924 rotates, it can drive the first worm wheel 927 meshing therewith to rotate. The first worm wheel 927 drives the first rotating rod 926 to rotate. The first rotating rod 926 drives the half gear 928 to rotate. When the half gear 928 rotates, it will intermittently mesh with the two tooth plates 9213, so that the two moving plates 929 can move. The sliding plate 9210 on the moving plate 929 can slide in the sliding groove of the fixed frame 921. When the half gear 928 is not in contact with one of the tooth plates 9213, the moving plate 929 at the tooth plate 9213 can The stretch spring 9212 is reset under the rebound action, so that the two moving plates 929 can perform intermittent reciprocating motion. When the moving plate 929 moves, the smoothing rod 9214 on the moving plate 929 can intermittently move back and forth along the width direction of the degradable tape 4, so that the degradable tape 4 can be stretched and smoothed. When the flattening rod 9219 on the limit slider 9116 is reciprocating, the upper end surface of the degradable tape 4 is further flattened. The telescopic spring 9217 arranged in the moving plate 929 can make the smoothing rod 9214 and the flattening rod 9219 close to the surface of the degradable tape 4, effectively preventing the degradable tape 4 from wrinkling during transmission, affecting the gluing effect and subsequent winding work;

[0064] When the first worm 924 rotates, the second rotating rod 9311 can rotate under the meshing transmission of the second worm wheel 9312. When the second rotating rod 9311 rotates, it drives the crank 9313 to rotate. When the crank 9313 rotates, the sliding column 9314 on the crank 9313 can slide in the arc frame 9310, and the arc frame 9310 drives the push rod 939 to move, so that the piston 938 reciprocates in the cylinder 935. When the piston 938 is pulled and moved, the glue in the glue box 931 can be transferred to the cylinder 935 through the feed pipe 936 under the action of air pressure. When the piston 938 is pushed back, the cylinder 935 The glue can be squeezed into the glue spray box 932 on the third mounting frame 6 through the discharge pipe 937. The one-way valves provided in the feed pipe 936 and the discharge pipe 937 can ensure that the glue is transported to the glue spray box 932. The glue is transported to the glue spray box 932 and then sprayed out through multiple glue spray heads 933 after being divided, so that the degradable tape 4 after dust removal starts to be coated with glue. After the glue is sprayed onto the degradable tape 4, it will be brushed by the brushing plate 9316. The brushing plate 9316 can be closely attached to the glue coating surface of the degradable tape 4 under the elastic potential energy of the tension spring 9319, ensuring that the glue can be evenly brushed on the glue coating surface of the degradable tape 4.

[0065] When the transmission roller 81 in the fourth mounting frame 7 rotates, the second worm gear 943 can rotate under the transmission action of the third belt drive group 944. The rotation of the second worm gear 943 can drive multiple third worm wheels 948 meshing therewith to rotate, thereby making multiple third rotating rods 946 on the fixed support plate 945 in the drying box 941 rotate. The third rotating rod 946 drives the fan blade 947 to rotate, and cooperates with the heating wire 949 to heat the inhaled air and blow it downward. The setting of the dustproof net 942 can prevent external dust from being sucked into the drying box 941, thereby drying the sprayed degradable tape 4, allowing the glue to solidify quickly, thereby improving the gluing efficiency of the degradable tape 4.
