Description

Technical Field

[0001] The invention relates to the technical field of carton processing, and in particular to a continuous labeling and sealing device for packaging carton processing. Background Art

[0002] A carton sealing machine is a type of machine that seals cartons with tape or the like. It consists of a conveying mechanism for conveying cartons, an upper movement for sealing the upper cover of the carton, a lower movement for sealing the lower cover of the carton, and other components.

[0003] Publication No. CN213891479U is a carton sealing machine, which is to place the carton to be sealed on a conveying device, start the conveying device to convey the carton from the channel to the inside of the chamber of the box body, and then start two sets of motors. Under the deceleration effect of the reduction box and the transmission effect of the first connecting rod and the second connecting rod, the connecting column is driven to rotate along the connection point between the connecting column and the first connecting ear, so that the glue brush reciprocates to apply sealing glue to the center line of the top of the carton, and then start the two sets of folding plate devices to press the sealing glue on the top of the carton and the top of the carton, and then start the conveying device again to convey the sealed carton to the next process, so as to facilitate the sealing of the carton and improve the degree of automation;

[0004] However, in the specific operation process, the above patented structure only realizes the sealing operation of folding the upper side of the carton in half and then performing the tape pasting. It is difficult to position the cardboard leaves on the top of the carton during the pasting process, which not only affects the accuracy of the tape position when sealing the carton, but also easily causes the cardboards on the opening and closing surfaces of the box to be unable to align and overlap, resulting in a large gap. In addition, due to the limited rotation angle of the above patented structure, the downward pressure height of the folding plate is forced to be relatively fixed, which cannot adapt to the folding of cartons of various specifications, further affecting the sealing efficiency of the carton.

[0005] In view of the technical defects in this aspect, a solution is now proposed. Summary of the invention

[0006] The purpose of the present invention is to make adaptive pressure on the opening and closing cardboards of the box body in multiple directions, forcing the two groups of opening and closing cardboards corresponding to the same side to align and overlap, thereby reducing the impact of tape sealing effect caused by offset or excessive gap between the opening and closing cardboards when sealing the box, which is beneficial to improving the overall airtightness of the carton.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention is provided with a storage plate, a push frame and a double limit mechanism. The carton is placed on the storage plate, and the bottom end is adaptively pressed by two sets of push frames. The second cylinder drives the inverted L-shaped vertical frame and the vertical plate to move to one side, and the top frame of the inverted L-shaped vertical frame extends to the outside of the limit frame and gradually presses on the top of the carton, and serves as the top limit of the carton. It cooperates with the bottom storage plate to press the upper and lower end surfaces of the carton together, so as to assist in the correction of the carton and keep the upper and lower adjacent opening and closing cardboards aligned;

[0019] As the top block continues to move, the circular axis on its top surface moves in a straight line along the corresponding inclined slot, and continuously pulls the slide plate to insert into the transverse slot, and forces the front and rear groups of branch clamping rods to approach each other and press against the outside of the corresponding opening and closing cardboards. Therefore, the upper and lower groups of branch clamping rods press against the outside of the front and rear groups of opening and closing cartons respectively, further keeping the upper and lower groups of cardboards on the same side aligned and overlapped, and reducing the gap between them, so that the tape can be positioned and adhered;

[0020] This structure helps align the two sets of opening and closing paperboards on the front and back opening and closing surfaces of the carton up and down to press them together to reduce the gap interval, so as to avoid the situation that the opening and closing paperboards are offset or the gap is too large when sealing the carton, which affects the sealing effect of the tape, thereby improving the overall airtightness of the carton. At the same time, the motor can be used to drive the storage plate to rotate 180 degrees to force the box body to turn over and repeat the above steps to achieve two-way sealing;

[0021] 2. The present invention also adjusts the spacing between the upper and lower rows of branch clamping rods according to the specifications of the box body of the box sealing by arranging an adjustment component and cooperating with the double limit mechanism. The motor is used to drive the two sets of limit gears to rotate clockwise, and the front and rear end limit gears are respectively engaged with the corresponding top frame 1 and top frame 2 to realize the upward or downward movement of the top frame 1 and top frame 2, and push the corresponding inverted L-shaped vertical frame and vertical plate to move upward or downward. The spacing between the inverted L-shaped vertical frame and the vertical plate increases, and the spacing between the upper and lower rows of branch clamping rods also increases accordingly, so as to adapt to the pressure limitation of the opening cardboard of cartons of more specifications.

DETAILED DESCRIPTION

[0032] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] An inclined material guide plate 4 is provided at the bottom end of the inner wall of one side of the inner slide groove 201, and one end of the material guide plate 4 extends to the lower end of the concave bottom frame 1, a concave slide frame 5 is slidably connected at the center of the inner slide groove 201, and a cylinder 6 is provided between the side of the concave slide frame 5 away from the opening end and the corresponding inner wall of the inner slide groove 201 through a push rod, a motor 7 is provided at the center of the inner wall at the bottom of the concave slide frame 5, and the top output end of the motor 7 is provided with a storage plate 8 extending to the upper end of the concave slide frame 5 and fixedly installed;

[0035] The limiting frame 2 is provided with a double limiting mechanism 9. When working, the semi-finished carton is placed on the surface of the storage plate 8, and the two sets of opening and closing paperboards at the upper and lower ends are respectively located at the front and rear ends of the carton (such as Figure 1 As shown), the closed cardboard which was originally the front side of the carton is placed facing downwards;

[0036] See also Figure 3As shown, the front and rear frames of the storage board 8 are respectively sleeved with a concave structure of the abutment frame 801, and the front and rear two sets of abutment frames 801 are mirror-symmetrical with respect to the central axis of the storage board 8. The top surfaces of the abutment frames 801 are arranged at both ends in a symmetrical chamfered surface, and a slot 802 is arranged at the midline of the top surface of the abutment frame 801.

[0037] A snap ring 803 is fixedly installed at the center of the front and rear ends of the top surface of the storage plate 8, and the snap ring 803 is slidably connected to the inside of the card slot 802. A damping spring shock absorber 804 is commonly arranged inside the card slot 802 between the snap ring 803 and the inner wall of one side of the card slot 802, and is pressed and limited by two groups of abutment frames 801 at the front and rear ends of the storage plate 8. The spacing between the two groups of abutment frames 801 is adjusted by moving forward and backward according to the width of the carton. The card slot 802 also moves synchronously with the abutment frame 801 and moves relative to the snap ring 803, forcing the damping spring shock absorber 804 to compress or rebound, so as to assist the abutment frame 801 to move stably until the bottom layer of the carton is adaptively clamped;

[0038] Then start the cylinder 1 6, which uses the push rod to push the concave sliding frame 5, the storage plate 8 and the carton to move to the limit frame 2, and after being limited by the double limit mechanism 9, the upper and lower pieces of open cardboards on the front and rear surfaces are forced to press and overlap, and then one end of the tape in the tape divider is pulled out and extended to the starting end position of the gap between the upper and lower sets of open and closed cardboards at the front end of the carton, and the tape is adhered to the carton, and the tape is cut off after being fitted along the front end gap to complete the single-sided sealing of the carton;

[0039] If double-sided sealing is required, the cylinder 6 is used again to pull the concave sliding frame 5 to move in the opposite direction and escape from the double limiting mechanism 9, and then the motor 7 is started to drive the storage plate 8 to rotate 180 degrees so that the unsealed surface at the rear end rotates forward, and then the cylinder 6 moves the flipped carton back to the double limiting mechanism 9 for pressing and limiting, and then repeats the above steps to seal the opening and closing cardboard at the front end, so as to achieve single-sided or double-sided sealing of the carton.

[0040] It is worth mentioning that after the box is sealed, the cylinder 6 can be used to pull the storage plate 8 and the carton to move toward the push rod 3, and the push rod 3 and the carton move relative to each other and press the carton in sequence, forcing the carton to leave the storage plate 8 and move toward the inner slide groove 201, and then be guided downward by the guide plate 4 to realize automatic unloading.

[0041] Example 2: Please refer to Figure 2 , Figure 4 - Figure 5 As shown, the double limiting mechanism 9 includes an inverted L-shaped vertical frame 91 and a vertical plate 92, the inverted L-shaped vertical frame 91 and the vertical plate 92 are movably arranged at one side of the interior of the limiting frame 2, the inverted L-shaped vertical frame 91 is movably arranged at the upper end of the vertical plate 92, and one end of the top frame of the inverted L-shaped vertical frame 91 is arranged in an oblique surface and extends to the outside of the limiting frame 2;

[0042] Sliding shafts 93 are fixedly installed at the bottom centers of both sides of the inverted L-shaped vertical frame 91 and the top centers of both sides of the vertical plate 92. A vertical frame 94 is slidably sleeved between the two sliding shafts 93 on the same side, and vertical grooves are arranged at the upper and lower ends of the vertical frame 94. The sliding shafts 93 are slidably connected in the corresponding vertical grooves. A cylinder 2 95 is arranged at the center of one side of one group of vertical frames 94 through a push rod, and the cylinder 2 95 is arranged at the center of the inner wall of one side of the limit frame 2 through a machine base. A concave card frame 96 is arranged at the rear end between the left and right groups of vertical frames 94.

[0043] A top block 97 is fixedly installed at the middle section of the front and rear end surfaces of the inverted L-shaped vertical frame 91 and the vertical plate 92, and a round shaft 98 is fixedly installed at the top position of the top block 97. One end of each group of top blocks 97 extends to the inside of the transverse groove 99 opened on the front and rear end surfaces of the limit frame 2, and a slide plate 910 is slidably connected inside the transverse groove 99 and at the upper end of the top block 97. An inclined groove 911 is opened on the top surface of the slide plate 910, and the top of the round shaft 98 is slidably connected to one end inside the inclined groove 911. A branch clamp rod 912 is fixedly installed on one side of the slide plate 910 and outside the transverse groove 99, and one end of the front and rear groups of branch clamp rods 912 extend to the side wall of the limit frame 2 respectively.

[0044] After the carton position is determined, the second cylinder 95 is started, which uses a push rod to push the vertical frame 94, the inverted L-shaped vertical frame 91 and the vertical board 92 to move to one side, and the top frame of the inverted L-shaped vertical frame 91 extends to the outside of the limit frame 2 and gradually presses on the top of the carton, and serves as the top limit of the carton. It cooperates with the bottom storage board 8 to press the upper and lower end surfaces of the carton together, so as to assist the carton correction while keeping the upper and lower adjacent opening and closing paperboards aligned;

[0045] The four groups of branch clamping rods 912 are respectively located at the front and rear opening and closing cardboards of the carton, and the top blocks 97 at the front and rear ends are driven to move continuously along with the inverted L-shaped vertical frame 91 and the vertical plate 92, and the circular shaft 98 on the surface of the top block 97 moves linearly along the corresponding inner wall of the inclined groove 911. Because the inner wall of the inclined groove 911 is resisted, the slide plate 910 is continuously pulled to insert into the transverse groove 99, and the front and rear groups of branch clamping rods 912 are forced to approach each other and press against the outside of the corresponding opening and closing cardboard. Therefore, the upper and lower groups of branch clamping rods 912 are respectively pressed against the outside of the front and rear groups of opening and closing cartons, further keeping the upper and lower groups of cardboards on the same side aligned and overlapped, and reducing the gap between them to facilitate the adhesion of the tape;

[0046] This structure helps to align the two sets of opening and closing paperboards on the front and rear opening and closing surfaces of the carton up and down and press them together to reduce the gap spacing, so as to avoid the problem of the opening and closing paperboards being offset or the gap being too large when sealing the carton, which may affect the tape sealing effect, thereby improving the overall airtightness of the carton.

[0047] Embodiment 3: Due to the differences in carton specifications, when sealing and pasting cartons of different specifications, the adjustment component 10 needs to be used to further adjust the positions of the upper and lower sets of branch clamping rods 912 to adapt to the pressing limit of cartons of various specifications;

[0048] See also Figure 4 , Figure 6 - Figure 8 As shown, an adjustment component 10 is provided at the inner wall of the rear end of the concave card frame 96, and the adjustment component 10 includes a second motor 101, and the second motor 101 is fixedly installed at the center of the inner wall of the rear end of the concave card frame 96, and a rotating rod 102 is fixedly connected to the output shaft at the front end of the motor 101, and the rotating rod 102 passes through the inverted L-shaped vertical frame 91 and the vertical plate 92 in sequence, and the outer portion of the rotating rod 102 is located at the front and rear ends of the interval between the inverted L-shaped vertical frame 91 and the vertical plate 92. The outer portion of the limiting gear 103 is respectively sleeved with a top frame 104 and a top frame 2 105;

[0049] The top frame 104 and the top frame 2 105 are movably arranged at the front and rear ends between the inverted L-shaped vertical frame 91 and the vertical plate 92, respectively, and the inner wall on one side of the top frame 104 and the inner wall on the other side of the top frame 2 105 are both provided with tooth groove groups, the top of the top frame 104 is hinged to the front end surface of the inverted L-shaped vertical frame 91, and the top frame 104 is internally located at the bottom end with a disc 106 fixedly installed at the front end of the vertical plate 92, the bottom of the top frame 2 105 is hinged to the rear end surface of the vertical plate 92, and the top frame 2 105 is internally located at the top end with a disc 106 fixedly installed at the rear end of the inverted L-shaped vertical frame 91.

[0050] When processing cartons of different sizes, the positions of the upper and lower rows of branch clamping rods 912 are adjusted. The specific adjustment steps include:

[0051] Start the second motor 101, and use the rotating rod 102 to drive the two sets of limit gears 103 to rotate clockwise, and the limit gear 103 at the front end is meshed with the tooth groove set on the side wall of the top frame 104 to realize the upward movement of the top frame 104, and the top end of the top frame 104 pushes the inverted L-shaped vertical frame 91 upward, and the disc 106 at the front end of the vertical plate 92 extends inside the top frame 104 and slides;

[0052] The limiting gear 103 at the rear end meshes with the tooth groove group at the side wall of the top frame 105, forcing the top frame 105 to transmit downward and press the vertical plate 92. At the same time, the disc 106 at the rear end of the inverted L-shaped vertical frame 91 slides relatively along the inside of the top frame 105. Therefore, the distance between the inverted L-shaped vertical frame 91 and the vertical plate 92 increases, and the sliding shafts 93 on the sides of the two slide along the corresponding vertical frames 94 respectively, and the distance between the upper and lower rows of branch clamping rods 912 also increases accordingly to adapt to the pressing limit of the opening cardboard of cartons of more specifications, thereby enhancing the practicality of the device.

[0053] Working principle: When the present invention is used, the semi-finished carton is first placed on the surface of the storage plate 8, and the two sets of opening and closing paperboards originally at the upper and lower ends are respectively located at the front and rear ends of the carton (such as Figure 1 As shown), the closed cardboard that was originally the front side of the carton is placed downward, and the abutment frame 803 is used to adaptively press the bottom of the carton;

[0054] Then start the cylinder 1 6, which uses the push rod to push the concave sliding frame 5, the storage plate 8 and the carton to move to the limit frame 2, and then start the cylinder 2 95, and use the push rod to push the vertical frame 94, the inverted L-shaped vertical frame 91 and the vertical plate 92 to move to one side, and the top frame of the inverted L-shaped vertical frame 91 extends to the outside of the limit frame 2 and gradually presses on the top of the carton, and serves as the top limit of the carton. It cooperates with the bottom storage plate 8 to press the upper and lower end surfaces of the carton together, so as to assist in the correction of the carton while keeping the upper and lower adjacent opening and closing cardboards aligned;

[0055] The four groups of branch clamping rods 912 are respectively located at the opening and closing paperboards at the front and rear of the carton, and the top blocks 97 at the front and rear ends are driven to move continuously by the inverted L-shaped vertical frame 91 and the vertical plate 92, and the circular shaft 98 on the surface of the top block 97 moves linearly along the corresponding inner wall of the inclined groove 911. Because the inner wall of the inclined groove 911 is resisted, the slide plate 910 is continuously pulled to insert into the transverse groove 99, and the front and rear groups of branch clamping rods 912 are forced to approach each other and press against the outside of the corresponding opening and closing paperboard. Therefore, the upper and lower groups of branch clamping rods 912 are respectively pressed against the outside of the front and rear groups of opening and closing cartons, further keeping the upper and lower groups of paperboards on the same side aligned and overlapped;

[0056] Then, one end of the tape in the tape divider is pulled out and extended to the starting end position of the gap between the upper and lower sets of opening and closing cardboards at the front end of the carton, and the tape is adhered to the carton, and the tape is cut off after being fitted along the front end gap to complete the single-sided sealing of the carton. If double-sided sealing is required, the cylinder 6 is used again to pull the concave sliding frame 5 to move in the opposite direction and escape from the double limiting mechanism 9, and then the motor 7 is started to drive the storage plate 8 to rotate 180 degrees so that the unsealed surface at the rear end rotates forward, and then the cylinder 6 moves the flipped carton back to the double limiting mechanism 9 for pressing and limiting, and then repeats the above steps to seal the opening and closing cardboard at the front end;

[0057] Finally, after the box is sealed, the cylinder 6 can be used to pull the storage plate 8 and the carton to move toward the push rod 3, and the push rod 3 and the carton move relative to each other and press the carton in sequence, forcing the carton to leave the storage plate 8 and move toward the inner slide groove 201, and the guide plate 4 is used to guide it downward to achieve automatic unloading.
