Description

Technical Field

[0001] The utility model relates to the technical field of packaging box laminating equipment, in particular to a simplified laminating machine. Background Art

[0002] In the field of packaging, in traditional technology, after the product packaging box is loaded, it is usually wrapped with film to enhance protection and appearance. Heat-sealed film packaging is one of the mainstream methods, which involves pre-making heat-sealed bags, that is, forming a bag with an opening by heat-sealing two layers of film, and then manually placing the packaging box and heating and shrinking it to ensure that the film fits tightly, achieving the dual purpose of beauty and protection.

[0003] In view of the low efficiency of manual operation and the difficulty in meeting the needs of large-scale production, the author of the present invention has recently applied for a fully automatic film laminating machine (refer to Chinese patent CN116812266A) to realize the automation of film laminating of packaging boxes. The core structure of the device is as follows:

[0004] A rack for mounting various mechanisms;

[0005] A film loading mechanism, arranged on the inner side of the frame, for conveying and unwinding the folded double-layer heat-sealing film roll;

[0006] A heat-sealing cutting mechanism is arranged at the upper end of the frame and docked with the film-loading mechanism, and is used to heat-melt-cut the double-layer heat-sealing film roll transversely to form a three-side sealed bag and a bag clamping position;

[0007] A bag pulling mechanism is arranged at the bag opening position on one side of the heat sealing and cutting mechanism, and is used to pull the three-side sealed bag made by the heat sealing and cutting mechanism along the bag clamping position to the bag opening position;

[0008] The bag-stretching and bag-moving mechanism is arranged on the same side of the bag-pulling mechanism and the heat-sealing and cutting mechanism and is located at the bag opening side of the three-side-sealed bag, and is used to stretch open the bag opening of the three-side-sealed bag pulled out by the bag-pulling mechanism, respectively clamp the upper and lower film layers of the stretched bag opening, blow open the three-side-sealed bag along the stretched bag opening, and move the blown-open three-side-sealed bag to the box-pushing position on the other side of the frame;

[0009] A packaging box conveying mechanism is provided at the box pushing position and located at the bag entry side of the bag opening, and is used to feed the packaging box and convey it to one side of the box pushing position;

[0010] A box pushing mechanism is arranged at the packaging box conveying mechanism position, and is used to push the packaging box along the box pushing position into the inner side of the bag opening of the three-side sealed bag, and to push the three-side sealed bag and the packaging box together to the bag sealing position on the other side of the box pushing position;

[0011] A bag sealing mechanism, arranged at the bag sealing position, for hot-melt sealing the bag opening of the three-side sealed bag to form a heat-sealed package;

[0012] A packaging box output mechanism, connected to the bag sealing position, is used to output the packaged packaging box to a subsequent heat drying device for heat drying and shrinking;

[0013] The edge sealing mechanism is arranged on both sides of the packaging box output mechanism and is used for heat-sealing the heat-sealed packaging at the four corners of the packaging box.

[0014] The above solution combines the moving line of heat-sealing film processing with the moving line of packaging box processing in a T-shaped distribution, integrating the processes of loading, bag making, bag opening and feeding, box pushing, heat sealing and edge sealing, significantly improving the efficiency of automated lamination.

[0015] However, the above solution still has the following limitations:

[0016] 1. The T-shaped structure makes the machine large in size, which is difficult to carry by conventional freight elevators. On-site installation requires breaking the wall, which is inconvenient to operate.

[0017] 2. The design of some components is not streamlined enough, which not only increases costs, but also causes waste of space and is not conducive to the overall optimization of the equipment.

DETAILED DESCRIPTION

[0054] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0055] See also Figures 1 to 10 , which is a simplified laminating machine as the best embodiment of the utility model, comprises a frame 10, a film loading mechanism 11, a heat sealing and cutting mechanism 12, a bag pulling mechanism 13, a bag supporting and moving mechanism 20, a packaging box input mechanism 14, a bag sealing mechanism 15, a packaging box output mechanism 16, a box pushing mechanism 17 and an edge sealing mechanism 18, and the upper end of the frame 10 forms an overall rectangular mounting surface 19;

[0056] Specifically, the packaging box input mechanism 14 has a first conveying mechanism (not shown in the figure) for linear transmission, the first conveying mechanism includes a first support frame 141, a first conveyor belt 142 that is transmission-connected between the two ends of the first support frame 141 in the length direction, and a first conveying motor 143 for driving the first conveyor belt 142 for transmission. The head end of the upper belt surface of the first conveyor belt 142 is located close to the edge of the mounting surface 19, and the end thereof forms an output position 144 for transferring the packaging box to the next workstation.

[0057] The packaging box output mechanism 16 has a second conveying mechanism (not shown in the figure) for linear transmission. The second conveying mechanism includes a second support frame 161, a second conveyor belt 162 connected between the two ends of the second support frame 161 in the length direction, and a second conveying motor (not shown in the figure) for driving the second conveyor belt 162 to transmit. The head end of the second conveyor belt 162 is parallel to one side of the end of the first conveyor belt 142 and forms an input position 163, so as to facilitate the continuous transition transmission of the packaging box. In addition, in order to realize the continuous backward transmission of the packaging box The second conveying mechanism also includes a pair of third conveyor belts 164 arranged in parallel. The third conveyor belt 164 is connected to the second conveyor belt 162 and the end of the third conveyor belt 164 extends to the other edge of the mounting surface 19 relative to the first conveyor belt 142, and is used to convey the packaging box backwards and reserve enough space for the packaging box with three-side sealed bags to be heat-sealed. The edge sealing mechanism 18 is arranged on both sides of the conveying path of the third conveyor belt 164, and the four corners of the packaging box covered with the three-side sealed bag are heat-sealed by a movable edge sealing device, and finally conveyed along the third conveyor belt 164.

[0058] In this embodiment, Figure 5 As shown, the heat-sealing cutting mechanism 12, the bag-pulling mechanism 13, the second conveying mechanism and the edge-sealing mechanism 18 are arranged in line in sequence to form a first working area A. The first conveying mechanism is arranged parallel to the first working area A and its output position 144 is parallel to and opposite to the input position 163 of the second conveying mechanism.

[0059] Specifically, the heat-sealing and cutting mechanism 12 is arranged at an edge position opposite to the head end of the first conveyor belt 142, and the bag-pulling mechanism 13 is distributed between the second conveyor belt 162 and the heat-sealing and cutting mechanism 12. The three-side sealed bag is formed by leading the double-layer heat-sealing film roll that is folded in half and rolled up to the heat-sealing and cutting mechanism 12 for continuous heat sealing and cutting, so as to form a three-side sealed bag with an opening on one side between the two continuously distributed cut edges. The double-layer heat-sealing film roll serving as the basis of the three-side sealed bag is folded in half and wound in the upper film mechanism 11, and its folded edge is located in a direction away from the first conveyor belt 142. The upper film mechanism 11 is arranged on the inner side of the frame 10 and below the heat-sealing and cutting mechanism 12. The bag-pulling mechanism 13 has a pair of clamping claws for clamping the two ends of the same side edge of the three-side sealed bag. The heat-sealing mechanism 131 and the bag-pulling device 132 for driving the clamping mechanism 131 to move toward or away from the heat-sealing and cutting mechanism 12, so that after the double-layer heat-sealing film roll is led out to the heat-sealing and cutting mechanism 12, it is first heat-sealed to form a first seal, and then the two sides of the first seal are clamped by the clamping mechanism 131 and pulled out in a direction away from the heat-sealing and cutting mechanism 12, and then the heat-sealing and cutting mechanism 12 heat-seals and cuts the double-layer heat-sealing film roll again to form a second seal, and at this time, a three-side sealed bag with an opening toward the first conveyor belt 142 is formed between the first seal and the second seal, and at this time, the two sides of the non-opening side of the three-side sealed bag are respectively fixed by the clamping mechanism 131 and the heat-sealing and cutting mechanism 12, so that the three-side sealed bag temporarily remains in a stable state and waits for subsequent transfer.

[0060] like Figure 5 As shown, a second working area B parallel to the first working area A is formed between the first conveying mechanism and the first working area A, and the bag sealing mechanism 15 is disposed in the second working area B, and the bag sealing mechanism 15 is located between the output position 144 of the first conveying mechanism and the input position 163 of the second conveying mechanism to form a heat sealing position C;

[0061] Specifically, the bag sealing mechanism 15 is a top-and-bottom structure, including a bag sealing base 151 and a heat-sealing seat 152 that can move up and down relative to the bag sealing base 151. The upper end height of the bag sealing base 151 is consistent with the upper end height of the first conveyor belt 142 and the second conveyor belt 162. The upper end of the bag sealing base 151 forms the aforementioned heat-sealing position C, so that when the three-side sealed bag is transferred to the heat-sealing position C, its opening faces the output position 144 of the first conveyor belt 142 and its main body is placed between the bag sealing base 151 and the heat-sealing seat 152. After the packaging box is pushed into the three-side sealed bag, the heat-sealing seat 152 is pressed down to heat-seal the open side of the three-side sealed bag, forming a complete and closed heat-sealed bag on the outer surface of the packaging bag. At this time, the four corners of the heat-sealed bag have not been processed yet, waiting to be subsequently conveyed to the third conveyor belt 164 and then heat-sealed and cut off by the edge sealing mechanism 18.

[0062] A bag taking position D is formed between the bag pulling mechanism 13 and the heat sealing and cutting mechanism 12. The bag holding and moving mechanism 20 includes a bag holding and moving device 40 and a linear driving device 30. The linear driving device 30 is placed in the second working area B and is used to move the bag holding and moving device 40 from the bag taking position D to between the heat sealing position C and the output position 144 of the first conveying mechanism.

[0063] Specifically, in the second working area B, along the direction from the first conveyor belt 142 to the second conveyor belt 162, the bag sealing mechanism 15 and the linear drive device 30 are staggered, the linear drive device 30 is located on the side close to the first conveyor belt 142, the bag sealing mechanism 15 is located on the side close to the second conveyor belt 162, and the linear drive device 30 extends along the bag taking position D to the heat sealing position C, so that the temporarily fixed three-side sealed bag can be transferred along the bag taking position D to the heat sealing position C, which is convenient for the subsequent process of pushing the box into the bag.

[0064] The box pushing mechanism 17 is arranged at the output position 144 of the first conveying mechanism, and includes a first box pushing device 171 and a second box pushing device 172. The first box pushing device 171 is used to push the packaging box into the three-side sealed bag at the heat sealing position C along the output position 144 of the first conveying mechanism, and the second box pushing device 172 is used to push the packaging box placed at the heat sealing position C and with the bag opening heat-sealed to the input position 163 of the second conveying mechanism.

[0065] Specifically, in this embodiment, the first box pushing device 171 and the second box pushing device 172 are both arranged in a linear shape and are both arranged on the side of the output position 144 of the first conveyor belt 142, consistent with the width direction of the first conveyor belt 142. The first box pushing device 171 is located at a lower position close to the belt surface of the first conveyor belt 142 and has a lever 173 and a lever 173 device (not marked in the figure, such as a motor, a cylinder, a synchronous belt 342, etc.) that drives the lever 173 to move along the width direction of the first conveyor belt 142. The second box pushing device 172 is located at the first conveyor belt 142. A box pushing device 171 is provided above the box pushing device 171 and has a push rod 174 and a dual-axis device (not shown in the figure) for driving the push rod 174 to move in the height direction and the width direction of the first conveyor belt 142. The end of the push rod 174 is designed to be a long rod so as to penetrate into the heat sealing position C to push the packaging box to the input position 163 of the second conveyor belt 162. The box pushing mechanism 17 is installed in the area at the end of the first conveyor belt 142 through a fixed frame, so as to make full use of the area and realize the smooth transition of the packaging box on the first conveyor belt 142 and the second conveyor belt 162.

[0066] Therefore, the maximum distance of the mounting surface 19 in the first horizontal direction is the width of the first conveying mechanism plus the width of the second working area B plus the width of the first working area A, and the maximum distance in the second horizontal direction is the distance between the head end of the first conveyor belt 142 and the end of the third conveyor belt 164 in the second direction, so that the entire laminating machine can be fully compressed to achieve further streamlining.

[0067] Preferably, Figure 6 As shown, in this embodiment, the linear driving device 30 includes a base 31 in the shape of a long plate, a first guide rail 32 arranged on the upper end surface of the base 31 and distributed along its length direction, a first slider 33 slidingly arranged on the first guide rail 32, and a first driving mechanism 34 for driving the first slider 33 to move along the guide rail.

[0069] Specifically, Figure 6 , 7 As shown in Figures 8 and 9, the base 31 is distributed in the length direction of the second working area B and is maintained in parallel with the conveying directions of the first conveyor belt 142 and the second conveyor belt 162. A pair of parallel first guide rails 32 are formed on the upper end surface of the base 31. A synchronous belt 342 that circulates along its length direction is provided on one side of the base 31.

The other side of the connecting plate 343 is clamped and fixed on the synchronous belt 342. The synchronous motor 341, the synchronous belt 342 and the connecting plate 343 constitute the aforementioned first driving mechanism 34. Therefore, when the synchronous motor 341 rotates, the end of the connecting plate 343 follows the synchronous belt 342 to move in its conveying direction, thereby driving the movable frame 41 to move along the length direction of the first guide rail 32, thereby realizing the reciprocating movement of the movable frame 41 between the bag taking position D and the heat sealing position C.

[0072] Preferably, Figure 7 , 9 As shown, the moving frame 41 is provided with an adjusting rod 70 above the bidirectional screw rod 50 at the uppermost end, and the adjusting rod 70 is provided with a driving gear 71 which can rotate circumferentially and adjust axially therewith, and a driving rack 72 which is vertically distributed and meshed with the driving gear 71 is provided on one side of the connecting rod 60, and an end of the adjusting rod 70 passes through one side of the moving frame 41 and is transmission-connected to a first driving motor 73 fixed to the moving frame 41, and a pair of limit blocks 511 are provided on the upper end surface of the adjusting seat 51, and the driving gear 71 is movably limited between the two limit blocks 511.

[0074] In this embodiment, Figure 7 , 8As shown, the adjusting rod 70 is arranged between the mounting plate 415 and the top of the long side plate 413 and is located above the bidirectional screw rod 50. The first drive motor 73 and the second drive motor 54 are both installed on the side of the long side plate 413 away from the short side plate 412. The output end of the first drive motor 73 is connected to the adjusting rod 70 through a bearing (not shown) arranged on the long side plate 413. The adjusting rod 70 is a square rod with a rectangular (or regular polygonal) cross section. The center of the driving gear 71 is provided with a square hole (or regular polygonal hole) adapted to the cross section of the adjusting rod 70. The end of the bidirectional screw rod 50 passes through the long side plate 413 away from the short side plate 412. A driving wheel 53 is coaxially provided on the outer wall away from the short side plate 412, and the second driving motor 54 is connected to the two driving wheels 53 through a synchronous toothed belt 55. Therefore, when the first driving motor 73 rotates, the adjusting rod 70 drives the driving gear 71 to rotate synchronously, and the driving rack 72 meshing with the driving gear 71 moves up or down along the tangent of the meshing position with the driving gear 71, thereby realizing the separation of the upper clamping jaw 43 and the lower clamping jaw 42, so that the upper side of the opening of the three-side sealed bag clamped by the upper clamping jaw 43 is pulled away from the lower side of the opening, so that the opening of the three-side sealed bag is fully opened, which is convenient for pushing in the subsequent packaging box.

[0075] Preferably, Figure 6 As shown, the upper clamping jaw 43 includes an upper limit plate 431 fixed horizontally to the bottom of the connecting rod 60 and an upper clamping cylinder 432 fixed on the connecting rod 60 and located directly above the upper limit plate 431, and the output shaft of the upper clamping cylinder 432 faces the upper limit plate 431; the lower clamping jaw 42 includes a lower limit plate 421 fixed horizontally above the adjustment seat 51 and a lower clamping cylinder 422 fixed at the bottom of the adjustment seat 51 and located directly below the lower limit plate 421, and the output shaft of the lower clamping cylinder 422 faces the lower limit plate 421, from An upper clamping position (not shown in the figure) for clamping the upper side of the opening of the three-side sealed bag is formed at the contact position between the upper limit plate 431 and the upper clamping cylinder 432, and a lower clamping position (not shown in the figure) for clamping the lower side of the opening of the three-side sealed bag is formed at the contact position between the lower limit plate 421 and the lower clamping cylinder 422. The two upper clamping positions and the two lower clamping positions respectively clamp and fix the four corners of the opening of the three-side sealed bag. When the two upper clamping jaws 43 move upward, the opening of the three-side sealed bag is opened to form a suitable size for the packaging box to be pushed in.

[0076] Preferably, Figure 7As shown, the end of the lower limit plate 421 away from the lower clamping cylinder 422 extends to the outside of the moving frame 41, and a baffle 423 distributed along the edge of the lower limit plate 421 close to the side wall of the moving frame 41 is vertically provided. The baffle 423 and the two lower limit plates 421 form a box pushing channel (not marked in the figure) for the packaging box to pass through. Therefore, when the moving frame 41 is driven to the heat-sealing position C, the baffle 423 and the end of the lower limit plate 421 are located close to the belt surface of the first conveyor belt 142, forming a box pushing channel, so that the packaging box can be pushed from the first conveyor belt 142 to the three-side sealed bag at the heat-sealing position C. At this time, the packaging box has been pushed onto the second conveyor belt 162, the open side of the three-side sealed bag is located in the second working area B, and the main part of the three-side sealed bag close to the first conveyor belt 142 is located at the heat sealing position C of the bag sealing mechanism 15. Therefore, when the bag sealing mechanism 15 heat-seals and cuts off the open side of the three-side sealed bag, the open side of the three-side sealed bag is heat-sealed to form a complete heat-sealed bag, which is then transmitted backward along the second conveyor belt 162, and its four corners are heat-sealed and cut off by the edge sealing mechanism 18 on the third conveyor belt 164, forming a heat-sealed bag shape that fits the packaging box, and then undergoes a corresponding heat drying process to make it completely heat-shrunk and fit onto the surface of the packaging bag.

[0077] Preferably, Figure 7 , 9 As shown, a position sensor 80 is provided at the top of the movable frame 41 in the moving direction of the adjusting seat 51, and a baffle 81 which can cooperate with the position sensor 80 is provided at the top of the connecting rod 60. In this embodiment, the position sensor 80 is a photoelectric sensor. Thus, through the cooperation of the baffle 81 and the photoelectric sensor, the position of the adjusting seat 51 can be accurately identified. By setting the position and number of the photoelectric sensors, the adjustment of the two adjusting seats 51 on the same bidirectional screw rod 50 can be realized, and adaptive adjustment can be performed on three-side sealed bags of different widths.

[0078] Preferably, Fig.10As shown in the figure, the mounting surface 19 is provided with a third guide rail 90 in the second working area B that moves in a direction approaching or away from the first working area A. The lower end of the base 31 is slidably disposed on the third guide rail 90 through a third slider 91. A yielding rack 92 that is linear and parallel to the third guide rail 90 is fixedly provided on the lower end surface of the base 31. A yielding motor 93 is provided on the mounting surface 19. A yielding gear that meshes with the yielding rack 92 is传动 provided on the output shaft of the yielding motor 93. In addition, in order to further increase the simplicity of the mechanism, the yielding motor 93 can be disposed between the lower end of the first support frame 141 and the mounting surface 19. Thus, when the yielding motor 93 operates, the yielding gear drives the yielding rack 92 engaged therewith to move along the extension direction of its length, so as to cooperate with the bag pulling mechanism 13 to achieve yielding. When the bag pulling mechanism pulls out the three-side sealed bag, the yielding motor 93 rotates, causing the base 31 to drive the moving frame 41 as a whole to yield to the bag pulling mechanism 13 and the three-side sealed bag. After the three-side sealed bag is pulled out to a proper position, the yielding motor 93 reverses, causing the base 31 to drive the moving frame 41 as a whole to move towards the three-side sealed bag, so that the upper limiting plate 431 of the upper clamping jaw 43 and the lower limiting plate 421 of the lower clamping jaw 42 simultaneously penetrate into the opening of the three-side sealed bag. At this time, the output shafts of the upper clamping cylinder 432 and the lower clamping cylinder 422 are both in the retracted state. The bag bodies on both sides of the opening of the three-side sealed bag are located between the upper limiting plate 431 and the upper clamping cylinder 432 and between the lower limiting plate 421 and the lower clamping cylinder 422. Thus, when the upper clamping cylinder 432 and the lower clamping cylinder 422 extend simultaneously, the bag bodies on the upper and lower sides of the opening of the three-side sealed bag are simultaneously clamped respectively. In addition, in order to facilitate the clamping of both sides of the opening of the three-side sealed bag, a bag hooking mechanism is preset on the bag pulling mechanism, so that when the three-side sealed bag is pulled out, its opening is in a pre-opened state, facilitating the penetration of the upper limiting plate 431 and the lower limiting plate 421. Moreover, blowing bag mechanisms of the blowing type are provided at the positions of the moving frame 41 at the upper clamping position and the lower clamping position, which can spray air currents to blow up the three-side sealed bag, so that the other unclamped end side thereof remains in a horizontal state and smoothly transitions to the heat sealing position C.

[0079] In order to facilitate the smooth transition of the three-side sealed bag and the moving frame 41 from the bag taking position D to the heat sealing position C, an opening and sinking mechanism (not shown in the figure) can also be designed on the mounting surface 19, so that the bag pulling mechanism 13 can sink as a whole, avoiding affecting the movement process of the three-side sealed bag and the moving frame 41.

[0080] In this embodiment, the moving frame 41 as a whole is designed as a U-shaped frame adapted to the length direction of the base 31, and the first driving motor 73 and the second driving motor 54 added on its outer side are both kept parallel to the length direction of the base 31, so that the moving frame 41 as a whole is limited within the second working area B, further streamlining the mechanism and making the overall volume of the equipment smaller.

[0081] The beneficial effects of the present utility model are as follows:

[0082] Firstly, the utility model divides the mounting surface 19 of the upper end face of the frame 10 into three parallel areas, arranges the heat-sealing cutting mechanism 12, the bag pulling mechanism 13, the second conveying mechanism and the edge sealing mechanism 18 in sequence on the linear first working area A, arranges the first conveying mechanism for box insertion in parallel on one side of the first working area A, and forms a second working area B parallel to the first working area A and the first conveying mechanism between the two, and arranges the bag sealing mechanism 15 and the bag supporting and moving mechanism 20 in parallel in the second working area B. Compared with the original T-shaped layout of the whole machine, the mounting surface 19 on the upper end of the frame 10 is extremely divided, and the streamlined mechanism makes the layout of each mechanism on the mounting surface 19 more reasonable, which is suitable for various types of freight elevator transportation without breaking the wall for installation, and is more convenient for the transportation and installation of the whole equipment.

[0083] In addition, by dividing the upper end surface of the frame 10 into a first working area A and a second working area B, a compact layout of the equipment is achieved, which significantly reduces the overall footprint, allowing the equipment to adapt to a smaller space and facilitate transportation and installation.

[0084] In addition, the laminating machine integrates multiple processes such as loading, bag making, bag opening and feeding, box pushing, heat sealing, and edge sealing. It has a high degree of automation, which effectively improves production efficiency and reduces labor costs.

[0085] In particular, by using a linear drive device 30, a streamlined bag-supporting and bag-moving mechanism 20, etc., unnecessary components are reduced, equipment costs are reduced, and space utilization is improved.

[0086] In summary, the utility model achieves a high degree of integration and streamlined design of the laminating machine by optimizing the layout, significantly improves the space utilization efficiency, makes the equipment more compact, easier to transport and install, is particularly suitable for standard freight elevators, does not require special installation conditions, and greatly facilitates users.

[0087] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
