Description

Technical Field

[0001] The invention relates to the technical field of paper box forming machines, in particular to a paper box forming corner pasting machine. Background Art

[0002] With the continuous development of economy and the continuous progress of science and technology, a strong technical support is provided for the vigorous development of forming equipment, so as to promote the development of forming equipment towards high centralization, high intelligence and high precision. The paper box forming machine is one of the many forming equipment, also known as gray board bending forming machine and four-corner pasting machine.

[0003] The forming process of the paper box forming machine in the prior art is to first cut off the four corners of the square bottom plate to form a cross-shaped bottom plate, then open a V-shaped groove between the four outer edges and the center of the cross-shaped bottom plate, and then move the bottom plate to the bottom of the mold. The mold is pressed down to make the four outer edges of the bottom plate turn up along the V-shaped groove to form the four side walls of the paper box, and then the folded paper box is taped at the side corners, and the four side walls of the paper box are taped at the corners where they are connected to each other to achieve final forming.

[0004] The molding operation realized by the above-mentioned molding machine needs to cut off the four corners of the square bottom plate at the beginning, and the cut four corners cannot be used again, resulting in waste; in response to this, a panel molding machine has appeared on the market, which uses a long strip bottom plate, only folds the front and rear outer edges, and the two sides are formed by splicing two side panels to form a paper box with four side walls. The two spliced ​​side walls formed by this method are not strong enough; the above-mentioned two types of equipment appear in the existing market, one is direct folding and corner pasting, and the other is a relatively improved panel and corner pasting. The two types of equipment operate independently, and most manufacturers produce a wide variety of products. The use of panel and corner pasting machines to produce paper boxes that can be panelized can reduce costs, but there are still many products that need to be produced using direct folding and corner pasting. At this time, manufacturers can only configure both types of equipment, which significantly increases the cost of daily maintenance. Summary of the invention

[0062] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments, and the contents mentioned in the implementation modes are not intended to limit the present invention.

[0063] like Figures 1 to 18 As shown, a paper box forming and corner gluing machine of the present invention comprises a frame 1, a bottom plate conveying device 2 installed on the frame 1, a molding device 3, a side corner gluing device 4 and a forming box output device 5;

[0064] It also includes a side plate conveying device 6 and a bottom edge gluing device 7 installed on the frame 1;

[0065] The frame 1 is provided with a molding area 11; the side corner gluing device 4, the bottom edge gluing device 7 and the molding box output device 5 are all located below the molding area 11, the molding device 3 is located above the molding area 11, the side plate conveying device 6 is located at one side of the molding area 11, and the bottom plate conveying device 2 is used to transfer the bottom plate to the molding area 11;

[0066] The bottom plate conveying device 2 includes a glue dispensing mechanism 21 for spraying glue on the bottom plate surface; the molding device 3 includes a lower die head 31 and a molding power element 32 for driving the lower die head 31 to move up and down; the molding power element 32 drives the lower die head 31 to move downward through the molding area 11 close to the molding box output device 5, and drives the lower die head 31 to move upward away from the molding area 11 to reset.

[0067] The invention discloses a paper box forming and corner pasting machine, which has two operation modes;

[0068] The first operation mode completes the carton forming by directly folding the edges and corners. The specific operation process is as follows;

[0069] The stacked bottom plates are placed on the loading seat 25 of the lifting and transferring mechanism 22 in the bottom plate conveying device 2, and the loading seat 25 is driven upward by the lifting power element 26 (see Figure 1 and Figure 2 ) Let the stacked bottom plates approach the picking-up robot 27, then the picking-up robot 27 sucks up the top layer of the stacked bottom plates through the suction cup, and then the lifting piece 29 in the horizontal transfer mechanism 23 moves forward to the bottom of the single bottom plate grabbed by the picking-up robot 27, and the picking-up robot 27 puts down the bottom plate, and the bottom plate falls to the upper side of the lifting piece 29 (the number of the lifting pieces 29 is two and they are spaced apart from each other to just abut the two sides of the lower side of the bottom plate, and the upper side of the lifting piece 29 is provided with a plurality of ventilation holes The horizontal power element 20 drives the lifting member 29 to move toward the molding area 11. When the lifting member 29 moves to the bottom of the brush 2a, the bottom plate contacts the brush 2a and continues to move for a certain distance. The air vents on the upper side of the lifting member 29 blow air and the bottom plate moves back. The bottom plate loses the force of being adsorbed by the lifting member 29 and is held by the brush 2a without moving. When the lifting member 29 moves back to the bottom of the picking-up robot 27, the pusher at the other end of the lifting member 29 just contacts the end surface of the bottom plate at the brush 2a (see FIG. Figure 4 and Figure 5 ), when the lifting member 29 moves toward the molding area 11 again, the pusher pushes the bottom plate to move to the bottom of the molding device 3 (that is, the bottom plate is moved to the bottom of the molding device 3 twice, and this design can shorten the travel of the lifting member 29);

[0070] Because the side plate conveying device 6 is provided with a bottom plate receiving member 6b, when the lifting member 29 moves the bottom plate to the bottom of the brush 2a, the bottom plate has entered the upper side of the bottom plate receiving member 6b, and the pusher pushes the bottom plate to move and slide along the upper side of the bottom plate receiving member 6b to the bottom of the molding device 3 (see Figure 6 and Figure 8 );

[0071] The molded power element 32 drives the molded plate 33 and the molded boss 34 to move downward, and the lower side of the molded boss 34 contacts the center surface of the bottom plate. The bottom plate moves further downward to approach the four side corner glue sticking devices 4 located below. Due to the design of the first guide surface 49 and the second guide surface 40 of the guide assembly 45, the four side walls connected to the center surface of the bottom plate are turned up along the V-shaped grooves between them to form a paper box shape (see Figure 10 to Figure 11 ), at this time, the third power element 4g drives the first tape outlet assembly 4e (the first tape outlet assembly 4e adopts the existing product on the market, that is, the tape is clamped by two rollers, and one of the rollers rotates to continuously output the tape) to output the tape from the first tape outlet, and the tape passes through the first tape outlet limiter 4f and extends out of its outlet with a preset length of tape. The paper box continues to move downward so that the tape sticks to its four corners, and then the second power element 4c drives the shaping member 4h to move forward and extend from the angle groove 4a to drive the first cutting knife 4b to cut the tape. Figures 11 to 15 , the direct folding and corner-tapping forming paper box is completed, and the molded boss 34 continues to push the formed and corner-taped paper box to fall to the forming box output device 5 for output; the forming box output device 5 can be driven by a conveyor belt and a motor to achieve output.

[0072] The second operation mode completes the carton forming by folding the edges, adding panels and then pasting the corners. The specific operation process is as follows;

[0073] The conveying action of the front section of the bottom plate is the same as that of the first operation mode, so it will not be described in detail. The main difference is that the bottom plate required for this operation mode is rectangular, and a V-shaped groove is provided between the center surface and the front and rear side walls for folding, and the side walls on both sides are provided by the side plate conveying device 6 and then spliced ​​and bonded; the specific operation is as follows:

[0074] When the bottom plate moves toward the molding area 11, the bottom plate moves through the back of the lifting and fixing frame 24, and the glue dispensing mechanism 21 installed at this position sprays glue on both sides of the side surface of the bottom plate (see Figure 2 and Figure 3), the lifting member 29 drives the bottom plate to continue to move to the bottom of the brush 2a, and the brush 2a touches the glue sprayed on the side of the bottom plate to brush the glue evenly. After the bottom plate touches the brush 2a and moves a certain distance, the vent on the side of the lifting member 29 blows air and moves back. The bottom plate loses the force of being adsorbed by the lifting member 29 and is held by the brush 2a without moving. When the lifting member 29 moves back to the bottom of the picking-up robot 27, the pusher at the other end of the lifting member 29 just touches the end face of the bottom plate located at the brush 2a. Figure 4 and Figure 5 When the lifting member 29 moves toward the molding area 11 again, the pusher pushes the bottom plate to move to the bottom of the molding device 3;

[0075] Then, the push plate mechanism 63 in the two side plate conveying devices 6 located on both sides of the molding area 11 pushes a side plate located at the bottom layer of the accommodating space 65 to the flip plate mechanism 64, and the side plate moves into the side plate clamping groove 6a of the clamping member 69 in the flip plate mechanism 64. Then, the flip plate power element 60 drives the flip plate rotating shaft 68 to rotate and drives the clamping member 69 to flip the side plate into an upright state. After the side plate is flipped up, it is tightly attached to the side wall of the molding boss 34 of the molding device 3 (see Figures 6 to 9 , the figure shows that there is a distance between the side panel conveying device 6 and the molding boss 34 of the molding device 3 in order to facilitate the structural position layout. Under normal circumstances, the side panel conveying device 6 is close to the molding boss 34 of the molding device 3, so that the flipped side panel is directly attached to the side wall of the molding boss 34);

[0076] After the side panel is tightly attached to the side wall of the molded boss 34, it is just above the position where the bottom plate is coated with glue. The molded boss 34 moves downward to push the side panel to the position where the glue is applied to the upper side of the bottom plate (at this time, the upper side of the side panel contacts the edge of the lower side of the molded plate 33 to achieve downward movement). At the same time, the front and rear side walls of the bottom plate are turned up into an upright shape due to the design of the first guide surface 49 and the second guide surface 40 of the guide assembly 45 in the four side corner glue sticking devices 4 located below and the downward pressure of the molded boss 34. The turned-up side walls on the front and rear sides of the bottom plate plus the two side walls of the two side panels form a paper box shape.

[0077] The paper box continues to move downward. At this time, the third power element 4g drives the first tape output component 4e (the first tape output component 4e adopts the existing product on the market, that is, the tape is clamped by two rollers, and one of the rollers rotates to continuously output the tape) to output the tape from the first tape outlet. The tape passes through the first tape outlet limiter 4f and extends out of its outlet with a preset length of tape. The paper box moves downward so that the tape sticks to its four corners, and then the second power element 4c drives the shaping member 4h to move forward and extend from the angle groove 4a to drive the first cutting knife 4b to cut the tape (see Figures 11 to 15 );

[0078] The paper box continues to move downward. At this time, the sixth power element 7g of the second tape output mechanism 75 in the bottom edge gluing device 7 drives the second tape output assembly 7e (the second tape output assembly 7e adopts an existing product on the market, that is, the tape is clamped by two rollers, and one of the rollers rotates to continuously output the tape) through the synchronous belt to output the tape from the second tape output port. The tape passes through the second tape output limiter 7f and extends from its outlet to a preset length. Then the fourth power element 74 in the bottom edge gluing device 7 starts to move forward along the connecting rod 78 and drives the sliding plate 73, the second tape output mechanism 75 and the second cutting mechanism 76 to move forward (see Figures 16 to 18 The fourth power element 74 is a cylinder. Since the extension rod of the cylinder, i.e. the extending end of the connecting rod 78, is fixedly connected to the floating seat 72, when the cylinder is in operation, the cylinder itself moves forward and backward);

[0079] The sliding plate 73, the second adhesive tape delivery mechanism 75 and the second cutting mechanism 76 are moved forward as a whole, so that the bottom supporting member 7a of the second cutting mechanism 76 extends to the bottom of the paper box, and the paper box is just supported when it falls. Since the bottom supporting member 7a is in an L-shaped shape, the adhesive tape extends to the extending end of the bottom supporting member 7a (see FIG. Fig.16 ), so when the paper box falls to the bottom supporting member 7a, its bottom edge just touches the tape and is stuck, and then the fifth power element 7c in the second cutting mechanism 76 drives the bottom supporting member 7a to drive the second cutting knife 7b to move further forward to cut the tape and complete the bottom edge gluing (the second base 71 and the floating seat 72 are connected by screws 79 and springs 70, and the floating seat 72 drives the bottom supporting member 7a to have a rebound force to press upward, so that the tape can be better adhered); the molded boss 34 continues to push the formed and corner-pasted paper box to fall to the forming box output device 5 for output; the forming box output device 5 can be driven by a conveyor belt and a motor to achieve output.

[0080] One device realizes two different operation modes. Manufacturers can complete the production of two different paper boxes with one device without two devices, thus reducing procurement costs. At the same time, only one device needs to be maintained on a daily basis, which significantly reduces daily maintenance costs compared to maintaining two devices.

[0081] In this embodiment, Figures 1 to 5 As shown;

[0082] The bottom plate conveying device 2 includes a lifting and conveying mechanism 22 and a horizontal conveying mechanism 23;

[0083] The lifting and transferring mechanism 22 includes a lifting fixed frame 24, a material carrier 25 mounted on the lifting fixed frame 24 for carrying the stacked bottom plates, a lifting power element 26 for driving the material carrier 25 to move up and down, and a picking robot 27 for picking up the topmost bottom plate from the stacked bottom plates;

[0084] The horizontal transfer mechanism 23 includes a horizontal fixed frame 28, a lifting member 29 mounted on the horizontal fixed frame 28 for receiving the bottom plate picked up by the picking-up robot 27, and a horizontal power element 20 for driving the lifting member 29 to reciprocate along the horizontal fixed frame 28 to approach the molding area 11 and the lifting transfer mechanism 22;

[0085] The glue dispensing mechanism 21 is installed on the lifting and fixing frame 24 and is located above the lifting member 29; the horizontal transfer mechanism 23 includes a brush 2a located above the lifting member 29; when the lifting member 29 drives the bottom plate located on its upper side to move toward the molding area 11, it passes under the glue dispensing mechanism 21 and the brush 2a.

[0086] The picking-up manipulator 27 is equipped with a suction cup, which is used for ventilation and blowing to suck up and put down the bottom plate; there are two lifting pieces 29, which are spaced apart from each other to just abut the two sides of the lower side of the bottom plate, and a plurality of ventilation holes are provided on the upper side of the lifting piece 29 for sucking and blowing off the bottom plate; the lifting piece 29 drives the bottom plate to move toward the molding area 11, first passes under the dispensing mechanism 21, and is abutted by the brush 2a when it moves under the brush 2a. When the bottom plate passes under the dispensing mechanism 21, if dispensing is required, it is dispensed. The glue mechanism 21 starts to spray glue on both sides of the side of the bottom plate to correspond to the splicing of the two side panels. If no glue is needed, the glue mechanism 21 will pass directly without being started; the position of the brush 2a corresponds to the two sides of the side of the bottom plate. When the bottom plate after glue is applied passes through the brush 2a, the brush 2a will evenly apply the glue; the brush 2a also plays a role in supporting the bottom plate to allow the lifting member 29 to move back. When the lifting member 29 transfers the second bottom plate, it pushes the previous bottom plate to the molding area 11, shortening the stroke of the lifting member 29 and improving the working efficiency.

[0087] In this embodiment, Figures 6 to 9 As shown;

[0088] There are two side plate conveying devices 6, and the two side plate conveying devices 6 are respectively located on both sides of the forming area 11 and are symmetrically arranged;

[0089] The side panel conveying device 6 includes a side panel fixing frame 61, two side panel clamping members 62, a pushing plate mechanism 63 and a flipping plate mechanism 64 installed on the side panel fixing frame 61; the two side panel clamping members 62 are spaced apart from each other to form a accommodating space 65 for accommodating the stacked side panels, the pushing plate mechanism 63 is located below the accommodating space 65 and is used to push out the bottom side panel of the stacked side panels, and the flipping plate mechanism 64 is located in front of the pushing plate mechanism 63 and is used to clamp and flip up a side panel pushed out by the pushing plate mechanism 63 to stand upright.

[0090] The side panel conveying device 6 is provided with a storage space 65 for storing the side panels. When the side panel splicing operation is performed, the side panel conveying device 6 is started to push out the side panels and flip them up to stand upright to form two side walls of the bottom panel and then splice them.

[0091] In this embodiment, the push plate mechanism 63 includes a push plate member 66 and a push plate power element 67 for driving the push plate member 66 to move back and forth. The reciprocating movement of the push plate member 66 can continuously push out the bottom side plate of the stacked side plates.

[0092] In this embodiment, the flap mechanism 64 includes a flap shaft 68, a clamping member 69 mounted on the flap shaft 68, and a flap power element 60 for driving the flap shaft 68 to rotate; the clamping member 69 is provided with a side plate slot 6a, which extends to connect the upper and lower end surfaces of the clamping member 69, and the side plate slides into the side plate slot 6a from the upper end surface of the clamping member 69 and slides out of the side plate slot 6a from the lower end surface of the clamping member 69;

[0093] When the push plate mechanism 63 pushes the side plate out, the entrance of the side plate slot 6a on the upper end surface of the clamping member 69 is horizontally aligned with the pushed side plate.

[0094] There are two clamping members 69, which are respectively installed at both ends of the flap shaft 68. After the side panels are pushed out, the two sides are inserted into the side panel slots 6a of the two clamping members 69. Then the flap power element 60 is started to make the flap shaft 68 drive the clamping members 69 to rotate so that the side panels are flipped up to an upright state.

[0095] After being turned up, the side plate is directly pressed against the side wall of the lower die head 31 , and the upper side surface of the side plate abuts against the edge of the molding plate 33 of the lower die head 31 and is pushed downward.

[0096] In this embodiment, the side plate conveying device 6 includes a bottom plate receiving member 6b installed on the side plate fixing frame 61 and a receiving power element 6c for driving the bottom plate receiving member 6b to move forward and backward;

[0097] The bottom plate receiving member 6b is used to lift the side of the bottom plate entering the molding area 11. When the molding device 3 pushes the bottom plate to move downward, the receiving power element 6c drives the bottom plate receiving member 6b to move backward.

[0098] When the lower die head 31 moves downward to push the bottom plate to fall, the side edge of the bottom plate is deformed and moves downward from the upper side surface of the bottom plate receiving member 6b.

[0099] In this embodiment, Figure 7 As shown;

[0100] The side corner gluing device 4 and the bottom edge gluing device 7 are located below the molding area 11 and are respectively arranged around the molding area 11; the bottom edge gluing device 7 is located below the side corner gluing device 4, and the molding box output device 5 is located below the bottom edge gluing device 7.

[0101] This position layout makes it easy to choose whether to enable the bottom plate gluing device. If you need to enable the bottom edge gluing, you can first glue the four side corners of the carton, and then glue the bottom edge after it is initially stabilized, making it easier to glue the bottom edge and more stable after gluing.

[0102] In this embodiment, Figures 10 to 15 As shown;

[0103] The side corner gluing device 4 comprises a first base 41 connected to the frame 1, a folding guide mechanism 42 installed on the first base 41, a first adhesive tape output mechanism 43 and a first cutting mechanism 44;

[0104] The folding guide mechanism 42 includes a guide assembly 45, two driving wheels 46, a guide belt 47 and a first power element 48; the guide assembly 45 includes a first guide surface 49 and a second guide surface 40 for contacting two adjacent side walls of the paper box, and the angle between the first guide surface 49 and the second guide surface 40 is matched with the angle between the two adjacent side walls of the paper box. The two driving wheels 46 are installed on the guide assembly 45 and are respectively close to the upper and lower ends of the first guide surface 49. The guide belt 47 is sleeved on the two driving wheels 46 and passes in front of the first guide surface 49. The first power element 48 drives the guide belt 47 to rotate;

[0105] An angle groove 4a is provided at the lower end portion where the first guide surface 49 and the second guide surface 40 are connected;

[0106] The first tape output mechanism 43 includes a first tape output port located in the angled slot 4a for outputting the tape; the first cutting mechanism 44 includes a first cutting knife 4b located in the angled slot 4a and a second power element 4c for driving the first cutting knife 4b to extend and cut the tape.

[0107] There are four side corner gluing devices 4, which correspond to the four side edges of the paper box respectively. The side edge of the paper box moves downward along the angle between the first guide surface 49 and the second guide surface 40, and then passes through the angle groove 4a. Then, the first tape outlet located in the angle groove 4a extends a preset length of tape to allow the side edge of the downward moving paper box to directly adhere during the downward movement. Then, the first cutting knife 4b extends out to cut the tape, leaving part of the tape on the side corner of the paper box.

[0108] In this embodiment, the second guide surface 40 is provided with an elastic sheet 4d, and the position of the elastic sheet 4d is close to the angle groove 4a. The four elastic sheets 4d of the four side corner gluing devices 4 push the paper box at the same time to make the gluing process stable and reliable.

[0109] In this embodiment, the first tape output mechanism 43 includes a first tape output assembly 4e, a first tape output stopper 4f and a third power element 4g; the first tape output port is arranged at the first tape output assembly 4e, and the first tape output port is aligned with the entrance of the first tape output stopper 4f;

[0110] The third power element 4g drives the first tape outlet assembly 4e through the synchronous belt to output the tape from the first tape outlet, and the tape passes through the first tape outlet limiting member 4f and extends from its outlet.

[0111] The first adhesive tape output assembly 4e can be a product currently available on the market, that is, a product that clamps the adhesive tape by two rollers, and one of the rollers rotates to continuously output the adhesive tape; the first adhesive tape output assembly 4e is the same as the second adhesive tape output assembly 7e, see Fig.17 The specific structure of the second tape outlet assembly 7e is shown.

[0112] The first tape-out limiting member 4f is used to limit the position of the extended tape, and the first cutting knife 4b is located on the lower side of the first tape-out limiting member 4f. The inner wall surface of the first tape-out limiting member 4f presses against the extended tape, allowing the first cutting knife 4b to quickly and reliably cut the tape.

[0113] In this embodiment, the first cutting mechanism 44 includes a shaping member 4h and a first heating tube 4i installed on the shaping member 4h; the first cutting blade 4b is installed on the shaping member 4h, and the second power element 4c drives the shaping member 4h to drive the first cutting blade 4b to extend. The shaping member 4h is long and extends along the length direction of the angle groove 4a, and the first heating tube 4i makes the shaping member 4h heat up as a whole and presses the tape against the side corner of the paper box.

[0114] In this embodiment, the shaping member 4h and the first cutting knife 4b are both provided with a cutting guide groove 4j, the cross-sectional shape of which is V-shaped; the cutting guide groove 4j is vertically aligned with the angle groove 4a and the angles of the two are matched and corresponded. The design of the cutting guide groove 4j allows the shaping member 4h and the first cutting knife 4b to work in close contact with the side corners of the paper box. The cutting guide groove 4j of the first cutting knife 4b facilitates cutting the tape in close contact with the side corners of the paper box, and the cutting guide groove 4j of the shaping member 4h allows the side corners of the paper box to move down closely to allow heat to be transferred to the tape attached to the paper box.

[0115] In this embodiment, Figures 16 to 18 As shown;

[0116] The bottom edge glue sticking device 7 comprises a second base 71, a floating base 72, a sliding plate 73, a fourth power element 74, a second adhesive tape output mechanism 75 and a second cutting mechanism 76; the second base 71 is connected to the frame 1, the floating base 72 is mounted on the second base 71 and can float up and down relative to the second base 71, the floating base 72 is provided with a slide groove 77 for the sliding plate 73 to be installed, the fourth power element 74, the second adhesive tape output mechanism 75 and the second cutting mechanism 76 are all mounted on the sliding plate 73, and the fourth power element 74 is provided with a connecting rod 78, one end of which is fixedly connected to the floating base 72;

[0117] The fourth power element 74 moves forward and backward along the connecting rod 78 , and drives the sliding plate 73 , the second adhesive tape output mechanism 75 and the second cutting mechanism 76 to move forward and backward together.

[0118] The floating seat 72 can float up and down relative to the second base 71. After the paper box falls and is caught by the bottom supporting member 7a of the second cutting mechanism 76, the floating seat 72 drives the bottom supporting member 7a to rebound upward and resist the bottom surface of the paper box, so that the adhesive tape attached to the bottom surface of the paper box is pushed and pressed tightly. The fourth power element 74 is activated to move forward along the connecting rod 78, driving the sliding plate 73, the second adhesive tape output mechanism 75 and the second cutting mechanism 76 to move forward together so that the bottom supporting member 7a extends out to catch the falling paper box.

[0119] In this embodiment, the bottom edge glue sticking device 7 further includes a screw 79 and a spring 70 sleeved on the screw 79; the end of the screw 79 passes through the floating seat 72 and is screwed to the second base 71, one end of the spring 70 abuts against the nut of the screw 79, and the other end of the spring 70 abuts against the floating seat 72; the floating seat 72 floats up and down along the screw 79. The elastic force of the spring 70 enables the floating seat 72 to float slightly up and down.

[0120] In this embodiment, the second cutting mechanism 76 includes a bottom supporting member 7a, a second cutting blade 7b installed on the bottom supporting member 7a, and a fifth power element 7c installed on the sliding plate 73 for driving the bottom supporting member 7a to move forward and drive the second cutting blade 7b to cut the tape; the cross-sectional shape of the bottom supporting member 7a is L-shaped. The L-shaped design of the bottom supporting member 7a makes it easier to support the bottom surface of the paper box.

[0121] In this embodiment, the bottom support 7a is provided with a second heating tube 7d, which heats the L-shaped adhesive tape cut into a whole so that the tape can be better adhered to the paper box.

[0122] In this embodiment, the second tape output mechanism 75 includes a second tape output assembly 7e, a second tape output stopper 7f and a sixth power element 7g; the second tape output assembly 7e is provided with a second tape output port, and the second tape output port is aligned with the inlet of the second tape output stopper 7f;

[0123] The sixth power element 7g drives the second tape outlet assembly 7e through the synchronous belt to output the tape from the second tape outlet, and the tape passes through the second tape outlet stopper 7f and extends out from its outlet.

[0124] The cooperation of the second tape outlet assembly 7e and the second tape outlet stopper 7f is the same as that of the first tape outlet assembly 4e and the first tape outlet stopper 4f. Fig.17 It can be seen that the specific structure of the tape delivery component is a design in which the tape is clamped by two rollers, and one of the rollers rotates to continuously output the tape.
