Description

Technical Field

[0001] This utility model relates to a sealing machine with double-sided roller pressing. Background Technology

[0002] In the packaging, food, pharmaceutical and daily chemical industries, heat sealing machines are widely used to seal flexible packaging materials such as plastic films and composite films. They melt the contact surfaces of the packaging materials by heating, apply pressure to fuse them, and then cool to form a strong and airtight seal.

[0003] Chinese Patent No. CN202421187061.9 discloses a sealing machine with convenient transmission, which realizes torque transmission between the output shaft and the rear roller shaft by setting a transmission sleeve. Specifically, the structure uses fasteners such as bolts to pass through the connecting groove and the limiting groove, and cooperate with the output shaft and the rear roller shaft to transmit the rotational power of the output shaft to the rear roller shaft. However, in the actual assembly process, it is necessary to accurately align the connecting groove of the output shaft, the limiting groove on the rear roller shaft and the corresponding hole on the transmission sleeve at the same time, which is quite cumbersome. Moreover, since the output shaft, the rear roller shaft and the transmission sleeve are all cylindrical rotating bodies, relative rotation between the components is easy to occur before the fasteners are fully tightened, resulting in alignment difficulties and affecting assembly efficiency and connection reliability.

[0004] Therefore, how to facilitate the connection between the output shaft and the rear roller shaft has become a problem that urgently needs to be solved by those in this technical field. Summary of the Invention

The second connecting part includes second mounting blocks protruding from both the top and bottom sides facing rearward, and each second mounting block has a first mating hole corresponding to each first insertion hole. The first connecting part has first mounting blocks protruding from both the left and right sides facing forward, and each first mounting block has a second mating hole corresponding to each second insertion hole.

[0007] The present invention is further configured such that: the output shaft is prismatic and the first connecting part is provided with a mounting groove and the mounting groove is adapted to the shape and size of the output shaft; the output shaft is bolted to the first connecting part; the second connecting part is bolted to the connecting shaft; the conveying mechanism also includes a baffle; the top of the conveyor belt is located above the baffle and a bearing is installed on the baffle; the bearing is sleeved on the connecting shaft.

[0008] The present invention is further configured such that: the workbench is rotatably mounted with a left pressure roller and a right pressure roller on the left and right sides of the hot pressing mechanism and the heat dissipation mechanism, and also includes a drive mechanism for driving the left pressure roller and the right pressure roller to rotate. The number of the left pressure roller and the right pressure roller are two, and they are respectively located on the upper and lower sides of the channel.

[0009] The present invention is further configured such that: the drive mechanism includes a geared motor, an output gear fixed to the geared motor, a lower gear meshing with the output gear, an upper gear meshing with the lower gear, an upper synchronous belt, and a lower synchronous belt; the upper gear is coaxially arranged with the upper left pressure wheel, and the lower gear is coaxially arranged with the lower left pressure wheel; the upper synchronous belt transmission is arranged between the upper left pressure wheel and the upper right pressure wheel, and the lower synchronous belt transmission is arranged between the lower left pressure wheel and the lower right pressure wheel.

[0010] The present invention is further configured such that: the driving mechanism includes a first mating belt and a second mating belt; the worktable is rotatably mounted with mating wheels on the left side of each left pressure roller; each left pressure roller includes a front mating section and an insertion groove is provided in each front mating section; the first mating belt is disposed between the mating section of the upper left pressure roller and the upper mating wheel; and the second mating belt is disposed between the mating section of the lower left pressure roller and the lower mating wheel.

[0011] The present invention is further configured such that: the workbench includes a mounting plate, the drive mechanism includes a connecting gear and a first mating gear, the lower gear is located to the right of the output gear and the connecting gear is located to the left of the output gear and meshes with it, the first mating gear meshes with the connecting gear, the first mating gear is coaxially arranged with the output shaft, a second mating gear is provided on the connecting shaft and a transmission gear meshing with the second mating gear is provided on the left transmission wheel.

[0012] The present invention is further configured to include a plurality of first mating springs and second mating springs. The hot pressing mechanism includes heating elements located on the upper and lower sides of the channel, and the heat dissipation mechanism includes heat dissipation elements located on the upper and lower sides of the channel. The upper heating element has a first mating body fixedly installed on the top left and right sides, and the upper heat dissipation element has a second mating body fixedly installed on the top left and right sides. Each first mating spring is located between the mounting plate and the first mating body, and each second mating spring is located between the mounting plate and the second mating body.

[0013] It also includes adjusting bolts, and the conveying mechanism also includes baffles located on the front and rear sides of the conveyor belt. The right conveying wheel includes a mounting shaft at the center position and a tensioning slider is fixed on the front side of the mounting shaft.

[0014] By adopting the above technical solution, in the process of torque transmission between the output shaft and the connecting shaft through the transmission sleeve, the first connecting part is first fixed to the output shaft and the second connecting part is fixed to the connecting shaft.

Since the first mounting block is located on the upper and lower sides of the first connecting part and connected to the upper and lower sides of the connecting member, and the second mounting block is located on the left and right sides of the second connecting part and connected to the left and right sides of the connecting member, the initial positioning can be achieved by simply inserting the first connecting part and the second connecting part during the assembly process. Furthermore, since the connecting member is cubic in shape, the first connecting part and the second connecting part will not rotate relative to the connecting member during the connection process. Moreover, due to the presence of the first mounting hole and the second mounting block, the first connecting part and the second connecting part can be stably positioned at different positions on the connecting member, effectively preventing rotation before the fastening bolts are inserted during the connection of the transmission sleeve with the output shaft and the connecting shaft, thus simplifying the assembly process and improving the efficiency and stability of the assembly connection.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-9As shown, this utility model discloses a sealing machine with double-sided roller pressing, including a worktable 1, a conveying mechanism 2 located in front of the worktable 1, a hot pressing mechanism 3 located on the worktable 1, a heat dissipation mechanism 4, and a channel 11 located on the worktable 1. Therefore, by placing the package to be hot-pressed on the conveying mechanism 2 so that the sealing position is located in the channel 11, the hot pressing mechanism 3 is activated to heat the sealing position, melting the contact surface and forming a seal (this is prior art and will not be described in detail here). It also includes a transmission sleeve 5. The conveying mechanism 2 includes a conveyor belt 21, a left conveyor wheel 22 located on the left side of the conveyor belt 21, and a right conveyor wheel 23 located on the right side of the conveyor belt 21. The worktable 1 rotates... An output shaft 12 is installed on the worktable 1. A connecting shaft 15 for linkage with the output shaft 12 is provided on the worktable 1. The connecting shaft 15 is linked with the left transmission wheel 22. The transmission sleeve 5 includes a first connecting part 51 fixedly connected to the output shaft 12 by a key connection, bolts, etc., a second connecting part 52 fixedly connected to the connecting shaft 15 by a key connection, bolts, etc., and a connecting member 53 located between the first connecting part 51 and the second connecting part 52. The connecting member 53 is cubic in shape and has first insertion holes 531 on the top and bottom sides and second insertion holes 532 on the left and right sides. The second connecting part 52 includes second mounting blocks 521 protruding from the top and bottom sides facing backward, and each second mounting block 521 is provided corresponding to each first insertion hole 531. The first connecting part 51 has a first mating hole 5111. First mounting blocks 511 protrude from both the left and right sides of the first connecting part 51 facing forward. Each first mounting block 511 has a second mating hole 5211 corresponding to each second insertion hole 532. By inserting bolts between the first mating hole 5111 and the first insertion hole 531, and between the second mating hole 5211 and the second insertion hole 532, the connection and fixation between the connecting part 53 and the first connecting part 51 and the second connecting part 52 can be completed, thereby completing the assembly of the transmission sleeve 5 between the output shaft 12 and the connecting shaft 15. During the torque transmission process between the output shaft 12 and the connecting shaft 15 using the transmission sleeve 5, the first connecting part 51 is first fixed to the output shaft 12, and then the second connecting part 52 is fixed to the connecting shaft 15. After fixing the shaft 15, either the first connecting part 51 is connected to the connector 53, or the second connecting part 52 is connected to the connector 53. Then, the other connecting part is inserted. Since the first mounting block 511 is located on the upper and lower sides of the first connecting part 51 and connected to the upper and lower sides of the connector 53, and the second mounting block 521 is located on the left and right sides of the second connecting part 52 and connected to the left and right sides of the connector 53, preliminary positioning can be achieved by simply inserting the first connecting part 51 and the second connecting part 52 during assembly. Furthermore, since the connector 53 is cubic in shape, the first connecting part 51 and the second connecting part 52 will not rotate relative to the connector 53 during the connection process.Furthermore, due to the presence of the first mounting hole and the second mounting block 521, the first connecting part 51 and the second connecting part 52 can be stably positioned at different positions on the connecting part 53, effectively preventing rotation before the fastening bolts are inserted during the connection of the transmission sleeve 5 with the output shaft 12 and the connecting shaft 15, thus simplifying the assembly process and improving the efficiency and stability of the assembly connection. Therefore, after the output shaft 12 is rotated, it can drive the left conveyor wheel 22 to rotate, so that the conveyor belt 21 can move the package that needs to be sealed.

[0020] The output shaft 12 is prismatic, and the first connecting part 51 is provided with a mounting groove 512, which is adapted to the shape and size of the output shaft 12. In this embodiment, the output shaft 12 is a quadrangular prism. The output shaft 12 is bolted to the first connecting part 51, and the second connecting part 52 is bolted to the connecting shaft 15. The conveying mechanism 2 also includes a baffle 25. The top of the conveyor belt 21 is located above the baffle 25, and a bearing 24 is installed on the baffle 25. The bearing 24 is fitted onto the connecting shaft 15. Since the output shaft 12 is prismatic, during the process of connecting the first connecting part 51 to the output shaft 12, the output shaft 12 cannot rotate relative to the first connecting part 51 after entering the mounting groove 512 that is adapted to its shape. This facilitates the bolting connection of the output shaft 12 to the first connecting part 53. The connecting shaft 15 is supported on the baffle 25 by the bearing 24, which effectively improves the stability of the left conveyor wheel 22 and makes the conveyor belt 21 move the packaging that needs to be sealed stably.

[0021] The workbench 1 is rotatably mounted with a left pressure roller 13 and a right pressure roller 14 on the left and right sides of the hot pressing mechanism 3 and the heat dissipation mechanism 4. It also includes a drive mechanism 6 for driving the left pressure roller 13 and the right pressure roller 14 to rotate. There are two left pressure rollers 13 and two right pressure rollers 14, which are located on the upper and lower sides of the channel 11 respectively. After the sealing machine is started, the drive mechanism 6 can drive the left pressure roller 13 and the right pressure roller 14 to rotate. Since there are two left pressure rollers 13 and two right pressure rollers 14, which are located on the upper and lower sides of the channel 11 respectively, after the package to be sealed is placed on the conveyor belt 21 of the conveying mechanism 2, the position to be sealed will first reach the right pressure roller 14 so that the contact surfaces on both sides of the sealing position are flat and attached together. Then, after the contact surfaces are heated and melted by the hot pressing mechanism 3, the heat sealing can be completed. After reaching the heat dissipation mechanism 4 for cooling and solidification to form a seal, it is pressed again by the right pressure roller 14 to improve the stability of the seal.

[0022] The drive mechanism 6 includes a geared motor 61, an output gear 611 fixed to the geared motor 61 by welding, keying, or other means, a lower gear 62 meshing with the output gear 611, an upper gear 63 meshing with the lower gear 62, an upper synchronous belt 64, and a lower synchronous belt 65. The upper gear 63 is coaxially arranged with the upper left pressure roller 13, and the lower gear 62 is coaxially arranged with the lower left pressure roller 13. The upper synchronous belt 64 transmits power between the upper left pressure roller 13 and the right pressure roller 14, and the lower synchronous belt 65 transmits power between the lower left pressure roller 13 and the right pressure roller 14. After the geared motor 61 is started, the output shaft 12 of the geared motor 61... The fixed output gear 611 rotates, and since the lower gear 62 meshes with the output gear 611 and can rotate, the upper gear 63 meshing with the lower gear 62 can also rotate, thereby causing the left pressure rollers 13 on both sides coaxially arranged to rotate. Since the upper synchronous belt 64 is set between the upper left and right pressure rollers 14 and the lower synchronous belt 65 is set between the lower left and right pressure rollers 14, the synchronous rotation of the upper and lower pressure rollers is achieved, thereby ensuring uniform pressure on the packaging material moving in the channel 11. At the same time, the two rotating pressure rollers can work together with the conveyor belt 21 to move the packaging material in the channel 11.

[0023] The drive mechanism 6 further includes a first mating belt 66 and a second mating belt 67. The worktable 1 is rotatably mounted with mating wheels 16 on the left side of each left pressure roller 13. Each left pressure roller 13 includes a front mating section 131, and each front mating section 131 is provided with an insertion groove 1311. The first mating belt 66 is disposed between the mating section 131 of the upper left pressure roller 13 and the upper mating wheel 16. The second mating belt 67 is disposed between the mating section 131 of the lower left pressure roller 13 and the lower mating wheel 16. Since there is a mating section 131 on the front side of each left pressure roller 13 for the first mating belt 66 and the second mating belt 67 to be inserted, during the rotation of each left pressure roller 13, the first mating belt 66 and the second mating belt 67 that are mated with it can be driven to rotate, so that the mating wheel 16 located on the other side of each mating belt can rotate accordingly, providing assistance for the movement of the sealing material and improving the stability of the material sealing during the sealing process.

[0024] The workbench 1 includes a mounting plate 17, and the drive mechanism includes a connecting gear 68 and a first mating gear 69. The lower gear 62 is located to the right of the output gear 611, while the connecting gear 68 is located to the left of the output gear 611 and meshes with it. The first mating gear 69 meshes with the connecting gear 68 and is coaxially arranged with the output shaft 12. A second mating gear 151 is provided on the connecting shaft 15, and a transmission gear 221 meshing with the second mating gear 151 is provided on the left transmission wheel. Because the first mating gear 69 and the connecting gear 68 mesh... Since gear 68 meshes, after the reduction motor 61 is started, the rotation of output gear 611 can drive the lower gear 62 and connecting gear 68 to rotate. Since the first mating gear 69 meshes with the connecting gear 68, the rotating connecting gear 68 can drive the first mating gear 69 and output shaft 12 to rotate. The output shaft 12 transmits torque to the connecting shaft 15 through the transmission sleeve 5, which in turn causes the second mating gear 151 to rotate, thereby driving the transmission gear 221 that meshes with the second mating gear to rotate, thus realizing the rotation of the left transmission wheel 22 and driving the transmission belt 21 to perform transmission.

[0025] The system also includes several first mating springs 7 and second mating springs 8. The hot pressing mechanism 3 includes heating elements 31 located on the upper and lower sides of the channel 11, while the heat dissipation mechanism 4 includes heat dissipation elements 41 located on the upper and lower sides of the channel 11. First mating bodies 311 are fixedly installed on the left and right sides of the top of the upper heating element 31, and second mating bodies 411 are fixedly installed on the left and right sides of the top of the upper heat dissipation element 41. Each first mating spring 7 is located between the mounting plate 17 and the first mating body 311, and each second mating spring 8 is located between the mounting plate 17 and the second mating body 311. Between the bodies 411, due to the presence of the first cooperating spring 7 and the second cooperating spring 8, when the packaging material to be sealed is placed between the two heating elements 31, the upper heating element 31 will move slightly upwards while the first cooperating spring 7 is compressed upwards. The elastic force of the first cooperating spring 7 will push the upper heating element 31 against the contact surface, thereby stabilizing the heating and achieving adhesion between the two contact surfaces. Similarly, the second cooperating spring 8 can make the upper heat dissipation element 41 press stably against the contact surface, thereby allowing the adhered contact surface to cool and solidify.

[0026] The system also includes an adjusting bolt 9. The conveying mechanism 2 also includes baffles 25 located on the front and rear sides of the conveyor belt 21. The right conveyor wheel 23 includes a mounting shaft 231 at the center, and a tensioning slider 2311 is fixed to the front side of the mounting shaft 231. The baffle 25 has a groove 251 for the tensioning slider 2311 to slide. The tensioning slider 2311 is inserted into the groove 251 and threadedly engaged with the adjusting bolt 9. The right conveyor wheel 23 is fixed to the tensioning slider 2311 through the mounting shaft 231. The slider 2311 is embedded in the groove 251 of the baffle 25 and threadedly engaged with the adjusting bolt 9. By rotating the adjusting bolt 9, the tensioning slider 2311 can be pushed to move along the groove 251, thereby changing the distance between the left and right conveyor wheels 23 and quickly adjusting the tension of the conveyor belt 21.

[0027] In addition, it is worth noting that the workbench 1 is equipped with a switch group for adjusting the speed of the conveyor belt 21, whether to start the hot pressing module, and whether to power on and heat the heating element (the specific linkage method is existing technology and will not be described here).

[0028] Furthermore, in this embodiment, channel 11 is located between upper synchronous belt 64, lower synchronous belt 65, first mating belt 66, and second mating belt 67. Upper synchronous belt 64, lower synchronous belt 65, first synchronous belt, and second synchronous belt are all made of high-temperature resistant material. The brass blocks within each heating element 31 can heat the sealing position through the upper synchronous belt 64, lower synchronous belt 65, first mating belt 66, and second mating belt 67. Each heat dissipation element 41 can cool the sealing position through the upper synchronous belt 64, lower synchronous belt 65, first mating belt 66, and second mating belt 67. The temperature controller used to control the heating element to heat the chalcopyrite is located within the workbench 1 and is linked to the switch. All of the above are existing technologies and can be referenced in Chinese Patent No. CN202321089060.6, "An Automatic Sealing Machine."

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
