[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 A heat-sealing packaging forming device comprises a frame 100 and a forming mechanism 200, a longitudinal sealing mechanism 300 and a transverse sealing mechanism 400 arranged on the frame 100. The forming mechanism 200 can guide the film material to curl and form it into a strip package with a cavity. The longitudinal sealing mechanism 300 comprises a first driver 310 and a longitudinal heat-sealing assembly 320. The longitudinal heat-sealing assembly 320 has a longitudinally arranged heating seat 321, and the heating seat 321 is detachably connected with a heat-sealing portion 322. The first driver 310 is drivingly connected to the longitudinal heat-sealing assembly 320 and can drive the longitudinal heat-sealing assembly 320 to move so that the heat-sealing portion 322 abuts against the curled and folded portion of the strip package to hot-melt-bond the curled and folded portion of the strip package. The transverse sealing mechanism 400 can perform transverse sealing on the strip package.

[0034] It is understandable that if Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, the forming mechanism 200, the longitudinal sealing mechanism 300, and the transverse sealing mechanism 400 are arranged in sequence from top to bottom, and the heat sealing part 322 is detachably arranged on the rear side of the heating seat 321. A heating tube 323 is inserted on the heating seat 321, and the heating seat 321 is heated by the heat generated by the heating tube 323. When in use, the film material for packaging is input into the forming mechanism 200, and the forming mechanism 200 guides the film material to be curled and formed into a strip package with a cavity. The first driver 310 drives the longitudinal heat sealing component 320 to move in the direction of the strip package, so that the heat sealing part 322 abuts against the curled and folded part of the strip package, and the heat is heated by conducting heat through the heating seat 321. The curled and folded part of the strip package is hot-melt bonded by the heat sealing part 322. As the strip package is conveyed downward, it moves relative to the heat sealing part 322, so that the heat sealing part 322 can continuously perform longitudinal sealing on the strip package, and then the strip package is sent to the transverse sealing mechanism 400, which performs transverse sealing on the strip package. The transverse sealing operation is performed at intervals, and materials are filled between the two intervals of transverse seals to achieve heat sealing packaging operations. By arranging the heat sealing part 322 to be detachable relative to the heating seat 321, when the heat sealing part 322 is worn out due to long-term use, the heat sealing part 322 can be removed and replaced separately without replacing the longitudinal heat sealing component 320 as a whole, thereby reducing maintenance costs and facilitating production applications.

[0035] In actual application, the first driver 310 can be a cylinder, a hydraulic cylinder, an electric push rod, etc. The specific structures such as the frame 100, the forming mechanism 200, the longitudinal sealing mechanism 300, the transverse sealing mechanism 400 can be set accordingly according to actual use needs. They are not described in detail here and are explained in detail below.

[0036] In some embodiments, the heating seat 321 is provided with a slot 324 extending in the up-down direction, the slot wall of the slot 324 is adapted to the outer profile of the heat sealing portion 322 , and the heat sealing portion 322 can be inserted into the slot 324 from the upper side of the slot 324 .

[0037] It is understandable that if Figure 4 and Figure 5As shown, the slot 324 is arranged at the rear side of the heating seat 321 and extends in the up-down direction. The horizontal cross-section of the slot 324 is a "T"-shaped structure, and the outer contour of the heat sealing part 322 is adapted thereto. The heating seat 321 is provided with a blocking member 325 at the lower side of the slot 324. The heat sealing part 322 can be inserted into the slot 324 from the upper side of the slot 324. The blocking member 325 blocks the heat sealing part 322 at the lower side of the slot 324 to limit its downward separation from the slot 324. The plug-in installation method makes the installation and disassembly of the heat sealing part 322 relatively simple and easy to use. Since the cross-section of the slot 324 is a "T"-shaped structure, the horizontal movement and rotation of the heat sealing part 322 are limited, the heat sealing part 322 is better fixed, and the possibility of its loosening is reduced. Moreover, the slot 324 with a "T"-shaped structure can increase the contact area with the heat sealing part 322, so as to facilitate the heat transfer between the two.

[0038] In actual application, the slot 324 can also be a dovetail groove structure. In addition to the plug-in installation method, the heat sealing part 322 can also be detachably connected to the heating seat 321 through a snap-on structure, a threaded structure, etc., which can be set accordingly according to actual use needs.

[0039] In some embodiments, the surface of the heat-sealing portion 322 that abuts against the strip packaging is provided with a Teflon material layer. It is understandable that during processing, the surface of the heat-sealing portion 322 may be sprayed with Teflon so that the surface of the heat-sealing portion 322 that abuts against the strip packaging has a Teflon material layer, which has an extremely low friction coefficient, makes the surface highly lubricated, reduces wear, and is also convenient for cleaning the abutting surface of the heat-sealing portion 322, making it easy to use.

[0040] In some embodiments, the longitudinal sealing mechanism 300 also includes a first movable frame 330, the first driver 310 is driven and connected to the longitudinal heat sealing assembly 320 through the first movable frame 330, the longitudinal heat sealing assembly 320 includes a first plate seat 326 and a first connecting pin 327, the heating seat 321 is connected to the first plate seat 326, one side of the first plate seat 326 is rotatably connected to the first movable frame 330, and the other side of the first plate seat 326 is fixed to the first movable frame 330 through the first connecting pin 327, and the first connecting pin 327 is removable.

[0041] It is understandable that if Figure 4 and Figure 5As shown in the figure, the first moving frame 330 has a "C" - shaped structure. The driving end of the first driver 310 is connected to the first moving frame 330. A plurality of heating seats 321 are provided and arranged in the left - right direction on the first plate base 326. Two first connecting pins 327 are provided and are respectively located on the left and right sides of the first plate base 326. The left and right sides of the first moving frame 330 are butted against the left and right sides of the first plate base 326. The first connecting pin 327 on the left side is inserted vertically into the left side of the first plate base 326 and the left side of the first moving frame 330, so that the left side of the first plate base 326 is rotatably connected to the left side of the first moving frame 330. The first connecting pin 327 on the right side is inserted vertically into the right side of the first plate base 326 and the right side of the first moving frame 330, so that the right side of the first plate base 326 is rotatably connected to the right side of the first moving frame 330. When in use, the first driver 310 drives the first plate base 326 to move through the first moving frame 330, thereby driving the longitudinal heat - sealing assembly 320 to move. When maintenance is required, any one of the first connecting pins 327 on the left and right sides can be detached, so that the first plate base 326 can be rotated and opened relative to the first moving frame 330, which is convenient for maintenance and also convenient for replacing and cleaning the heat - sealing part 322, facilitating use.

[0042] In actual application, only one first connecting pin 327 can also be provided, so that the first plate base 326 can be rotated and opened on one side. The first connecting pin 327 can be a plug or a threaded part. The specific structures of the first moving frame 330, the first plate base 326, etc. can be set accordingly according to actual use requirements.

[0043] In some embodiments, the forming mechanism 200 includes a guide member 210, a forming plate 220, and a mandrel 230. The guide member 210 is provided on the upper side of the forming plate 220. The forming plate 220 is provided with a forming groove 221 that penetrates up and down. The mandrel 230 passes through the guide member 210 and extends into the forming groove 221. The groove side of the forming groove 221 corresponding to the heat - sealing part 322 is provided with an open structure. The guide member 210 can guide the film material to curl and wrap around the outside of the mandrel 230. The film material curled and wrapped around the outside of the mandrel 230 can be sent along the mandrel 230 into the forming groove 221 and the curling and closing part faces the heat - sealing part 322.

[0044] It can be understood that, such as Figure 1 、 Figure 2 and Figure 3As shown, the forming plate 220 is connected and fixed to the frame 100, and is provided with a plurality of forming grooves 221, which are arranged in the left-right direction, and the forming grooves 221 are connected up and down, and the front side thereof is an open structure for the heat sealing part 322 to extend therein; the guide member 210 is arranged on the upper side of the forming plate 220 and is provided with a plurality of corresponding forming grooves 221, and is provided with a curved surface structure and a slot hole for guiding the curling of the film material, and the core rod 230 passes through the slot hole of the guide member 210 and extends into the forming groove 221. When in use, the film material is conveyed to the guide 210, and the guide 210 guides the film material to curl and wrap around the outside of the core rod 230. Subsequently, the film material (strip packaging) curled and wrapped around the outside of the core rod 230 is conveyed to the molding groove 221 along the core rod 230, and the curled and folded part faces the heat sealing part 322. The heat sealing part 322 abuts against the curled and folded part to perform hot-melt bonding on it to achieve longitudinal sealing of the strip packaging. In actual application, in addition to the above structure, a curved surface structure can be set at the film material input port of the molding groove 221 to guide the film material to curl into a strip packaging with a cavity. The specific setting quantity and distribution of the guide 210, molding groove 221, etc. can be set accordingly according to actual use needs.

[0045] Further, a feeding channel for material transportation is provided inside the core rod 230. It is understandable that by providing the feeding channel inside the core rod 230, when in use, materials can be transported to the strip packaging through the feeding channel, which is convenient for use.

[0046] In some embodiments, the transverse sealing mechanism 400 includes a second driver 410, a third driver 420, a first transverse heat sealing assembly 430 and a second transverse heat sealing assembly 440. The second driver 410 is drivingly connected to the first transverse heat sealing assembly 430 and can drive the first transverse heat sealing assembly 430 to move. The third driver 420 is drivingly connected to the second transverse heat sealing assembly 440 and can drive the second transverse heat sealing assembly 440 to move, so that the first transverse heat sealing assembly 430 and the second transverse heat sealing assembly 440 can move closer to or away from each other, so as to form a horizontal clamp on the strip packaging and perform hot melt bonding at the clamping position.

[0047] It is understandable that if Figure 1 , Figure 2 and Figure 6As shown, the driving directions of the second driver 410 and the third driver 420 are opposite. The two respectively drive the first transverse heat-sealing assembly 430 and the second transverse heat-sealing assembly 440 to move, so that the first transverse heat-sealing assembly 430 and the second transverse heat-sealing assembly 440 move closer to each other, horizontally clamp the strip packaging, and heat-seal at the clamping position to complete the transverse sealing of the strip packaging. In actual application, in addition to the above structure, a motor can also be used to drive the threaded rod to rotate, and threads with opposite helix directions are provided on the threaded rod to drive the linkage structures on both sides to move closer or farther away respectively, so as to realize the driving of the first transverse heat-sealing assembly 430 and the second transverse heat-sealing assembly 440. Specifically, it can be set according to actual usage needs.

[0048] Further, the transverse sealing mechanism 400 further includes a second moving frame 450. The second driver 410 is drivingly connected to the first transverse heat-sealing assembly 430 through the second moving frame 450. The first transverse heat-sealing assembly 430 includes a second plate seat 431 and a second connecting pin 432. One side of the second plate seat 431 is rotatably connected to the second moving frame 450, and the other side of the second plate seat 431 is fixed to the second moving frame 450 through the second connecting pin 432, and the second connecting pin 432 is detachable.

[0049] It can be understood that, as Figure 1 、 Figure 2 and Figure 6 shown, the transverse sealing mechanism 400 further includes a third moving frame 460. Both the second moving frame 450 and the third moving frame 460 are in a "C" shape. The driving end of the second driver 410 is connected to the second moving frame 450, and the driving end of the third driver 420 is connected to the third moving frame 460. The second transverse heat-sealing assembly 440 is fixedly connected to the third moving frame 460. The right side of the second plate seat 431 is rotatably connected to the second moving frame 450 through a rotating shaft. The second connecting pin 432 is arranged on the left side of the second plate seat 431. The left side of the second moving frame 450 is docked with the left side of the second plate seat 431. The second connecting pin 432 is inserted vertically through the left side of the second plate seat 431 and the left side of the second moving frame 450 to connect the left side of the second plate seat 431 and the left side of the second moving frame 450. When in use, the second driver 410 drives the second plate seat 431 to move through the second moving frame 450, thereby driving the first transverse heat-sealing assembly 430 to move. The third driver 420 drives the second transverse heat-sealing assembly 440 to move through the third moving frame 460. When maintenance is required, the second connecting pin 432 can be detached, so that the second plate seat 431 can be rotated and opened relative to the second moving frame 450, which is convenient for maintenance and use. In actual application, the second connecting pin 432 can be a plug or a threaded part. The specific structures of the second moving frame 450, the second plate seat 431, the third moving frame 460, etc. can be set according to actual usage needs.

[0050] Furthermore, the transverse sealing mechanism 400 also includes a fourth driver 470 and a slide 480. The slide 480 is slidably connected to the frame 100. The second driver 410 and the third driver 420 are both fixedly connected to the slide 480. The fourth driver 470 is drivingly connected to the slide 480 and can drive the slide 480 to move up and down.

[0051] It is understandable that if Figure 1 , Figure 2 and Figure 6 As shown, the slide 480 is connected to the frame 100 by being movable up and down through the guide rod, the second driver 410 and the third driver 420 are both fixedly connected to the slide 480, and the second movable frame 450 and the third movable frame 460 are both horizontally movable and connected to the slide 480. When in use, the strip package is clamped by driving the first transverse heat sealing component 430 and the second transverse heat sealing component 440, and then the fourth driver 470 drives the slide 480 to move downward to pull the strip package and transport it downward, so as to realize the downward pulling and conveying of the upper strip package and the film material; after the slide 480 moves downward by a preset distance, the first transverse heat sealing component 430 and the second transverse heat sealing component 440 move apart to release the clamping of the strip package, at this time, the fourth driver 470 drives the slide 480 to move upward and reset, and the above clamping and pulling actions are repeated later to realize the interval transverse sealing of the strip package.

[0052] Specifically, the transverse sealing mechanism 400 also includes a rocker member 471 and a connecting rod member 472. The two ends of the connecting rod member 472 are rotatably connected to the rocker member 471 and the slide 480 respectively. The rocker member 471 is connected to the driving end of the fourth driver 470 and can be driven by the fourth driver 470 to swing, so as to drive the slide 480 to move up and down through the connecting rod member 472.

[0053] It is understandable that if Figure 1 , Figure 2 and Figure 6 As shown, the fourth driver 470 is a swing driver, whose driving end is connected to the rocker member 471, and is used to drive the rocker member 471 to swing. The upper and lower ends of the connecting rod member 472 are respectively connected to the rocker member 471 and the slide 480 for rotation, thereby forming a rocker slider structure. Through the swing of the rocker member 471, the slide 480 can be moved up and down periodically, which is convenient for use. In actual application, in addition to the above structure, the slide 480 can also be directly driven up and down by a linear driver, such as a cylinder, a hydraulic cylinder, etc., which can be set accordingly according to actual use needs.

[0054] Furthermore, the frame 100 is provided with a stroke detection component 110 corresponding to the movement of the slide 480, which is used to detect the up and down movement of the slide 480, improve reliability and facilitate feedback control of the swing amplitude of the rocker member 471 to control the up and down movement of the slide 480, which is convenient for use. In actual application, the stroke detection component 110 may include an infrared sensor, a Hall sensor, a micro switch, etc., to detect the up and down movement of the slide 480, which can be set accordingly according to actual use needs.

[0055] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
