[0002] At present, most of the nylon sheet film forming processes in the food industry are sheet electrode heat sealing and welding. The welding width is affected by the electrode and is usually only one millimeter wide. When the nylon film size is large and the product weight is increased, the thin welding position can no longer meet the high yield rate.

Widening the electrode will cause the welding position to melt and deform at high temperature, and the appearance will be distorted.

DETAILED DESCRIPTION

[0025] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] like Figure 1-7 As shown, the present invention proposes a clipping machine chain drive steel belt heat sealing welding device including a connecting component 1, a transmission component 2, a sealing welding component 3 and a driving component 4. The sealing welding component 3 includes a heating mechanism, a steel belt 31 and a pulley 32. The steel belt 31 is sleeved on the pulley 32 to form a belt drive. The heating mechanism is used to heat the steel belt 31. The connecting component 1 is used to adjust the distance and angle between the steel belt 31 and the cylindrical casing rolled into a sheet nylon casing. The driving component 4 is used to drive the pulley 32 to rotate through the transmission component 2. The steel belt 31 is used to heat seal the cylindrical casing.

[0027] It can be understood that the heating mechanism first heats the steel belt 31 to a predetermined temperature. When the sheet nylon casing is rolled into a cylindrical casing, it is transmitted to the clipping machine chain drive steel belt heat sealing device. The position of the clipping machine chain drive steel belt heat sealing device is fine-tuned by connecting component 1, so that the steel belt 31 fits the position of the cylindrical casing that needs to be sealed, and the driving component 4 drives the pulley 32 to rotate through the transmission component 2, thereby driving the steel belt 31 to move along with the cylindrical casing transmission, thereby continuously heat sealing the cylindrical casing.

[0028] It can be understood that, compared with the situation where the traditional welding width is affected by the electrode, the heat sealing method of the steel strip 31 can achieve a better sealing effect even when the nylon film size is large.

[0029] It should be noted that the moving speed of the steel belt 31 is consistent with the transmission speed of the tubular casing, so as to avoid the tubular casing being involved in the heat sealing process.

[0030] Furthermore, the sealing welding assembly also includes a pulley cover 33 , which is connected to the transmission assembly 1 , the steel belt 31 is exposed from the pulley cover 33 , and the heating mechanism is located between the steel belt 31 and the pulley 32 and is in contact with the steel belt 31 .

[0031] In this embodiment, the pulley cover 33 has at least two side openings, and the steel belt 31 is exposed from one side of the opening, so as to contact with the tubular casing to achieve heat sealing. The transmission component 2 enters the pulley cover 33 from the other side and is connected to the pulley 32 for transmission, thereby driving the pulley 32 to rotate, that is, driving the steel belt 31 on the pulley 32 to move.

[0032] In this embodiment, there are two pulleys 32, and a belt transmission is formed between the two pulleys 32 and the steel belt 31, thereby driving the steel belt 31 to move. In some embodiments, there may be any number of pulleys 32, as long as the steel belt 31 can be driven to move by the pulleys 32, and the moving speed is consistent with the transmission speed of the tubular casing.

[0033] Furthermore, the heating mechanism includes a heating block 34 and a heating connection seat 35 . The heating connection seat 35 is connected to the transmission assembly 2 . The heating block 34 is connected to the heating connection seat 35 and is in contact with the steel belt 31 .

[0034] Furthermore, the heating mechanism also includes an isolation cover 36 and a heating baffle 37. The isolation cover 36 is connected to the side wall of the heating block 34 close to the pulley cover 33. The heating block 34 is located in the isolation cover 36. The heating baffle 37 is connected to the side of the isolation cover 36 away from the pulley cover 33.

[0035] It can be understood that the heating connecting seat 35 serves to fix and support the heating block 34, and the isolation cover 36 and the heating baffle 37 are used to prevent the heat of the heating block 34 from spreading to places other than the steel belt 31, such as preventing the heating block 34 from heating other components such as the pulley cover 33 and the pulley 32.

[0036] It can be understood that the isolation cover 36 can be of any structure and material as long as it can prevent the heating block 34 from heating components other than the steel strip 31 .

[0037] In this embodiment, the isolation cover 36 and the heating baffle 37 are respectively connected to the opposite sides of the heating block 34 and then assembled onto the heating connection base 35 .

[0038] Furthermore, the transmission assembly 2 includes a connecting vertical plate 21, a transmission shaft 22, a transmission bearing 23 and a transmission bearing seat 24. The transmission bearing seat 24 is connected to the connecting vertical plate 21. The transmission shaft 22 passes through the transmission bearing seat 24 and is rotatably connected to the transmission bearing seat 24 through the transmission bearing 23. One end of the transmission shaft 22 is plugged into the pulley 32, and the end away from the pulley 32 is transmission-connected to the drive assembly 4.

[0039] It can be understood that the connecting plate 21 is located between the sealing assembly 3 and the driving assembly 4, and the driving assembly 4 drives the transmission shaft 22 to rotate, thereby driving the pulley 32 to rotate, and then the belt drive is used to realize the movement of the steel belt 31.

[0040] In this embodiment, the pulley cover 33 is connected to the connecting vertical plate 21 of the transmission assembly 2 .

[0041] Furthermore, the driving assembly 4 includes a motor 41, a driving sprocket 42, a transmission sprocket 43 and a chain 44. The driving sprocket 42 is connected to the output end of the motor 41. The transmission sprocket 43 and the driving sprocket 42 are both engaged with the chain 44 to form a chain drive. The end of the transmission shaft 22 away from the pulley 32 is connected to the transmission sprocket 43.

[0042] It can be understood that the motor 41 provides power to drive the driving sprocket 42 to rotate, and uses the chain 44 to drive the transmission sprocket 43 to rotate. The transmission sprocket 43 drives the transmission shaft 22 to rotate, thereby driving the pulley 32 to rotate, thereby achieving the effect of driving the steel belt 31 to move.

[0043] In this embodiment, the number of the transmission shaft 22 and the driving sprocket 42 is the same as the pulley 32, that is, two. The two transmission sprockets 43 and one driving sprocket 42 are distributed in a triangle to support the chain and are respectively engaged with the chain 44 to form a chain drive.

[0044] Furthermore, the transmission shaft 22 and the transmission sprocket 43 are connected in a limiting manner via a spacer ring 45 .

[0045] Furthermore, the driving assembly 4 also includes a motor connecting seat 45 , and the motor 41 is connected to the motor connecting seat 45 .

[0046] It can be understood that the motor connection seat 46 can be set at any place as long as it can fix the motor 41 so that the motor 41 can drive the driving sprocket 42 to rotate.

[0047] Furthermore, the driving assembly 4 also includes a chain cover 47 , and the chain cover 47 is arranged on the periphery of the chain 44 .

[0048] Furthermore, the connecting assembly 1 includes a top plate 11, a connecting block 12, a screw rod 14, a slider 15, a rotating block 16 and a cylinder 17. The top plate 11 is connected to other components. There are two connecting blocks 12. The two connecting blocks 12 are connected to opposite sides of the top plate 11. The screw rod 14 passes through the slider 15 and is threadedly transmitted with the slider 15, and the two ends are respectively rotatably connected to the two connecting blocks 12. The rotating block 16 is rotatably connected to one end of the slider 15 away from the top plate 11. The transmission assembly 2, the sealing assembly 3 and the driving assembly 4 are all connected to the rotating block 16. The cylinder 17 is used to drive the rotating block 16 to rotate relative to the slider 15.

[0049] It can be understood that by rotating the screw rod 14, the slider 15 can be driven to move through the threaded transmission, and then the rotating block 16 under the slider 15 can be driven to move, and finally the transmission assembly 2, the sealing assembly 3 and the driving assembly 4 can be driven to move along the axis direction of the screw rod 14 to adjust the distance between the steel belt 31 and the cylindrical casing. The rotating block 16 is driven by the cylinder 17 to rotate relative to the slider 15, and then the transmission assembly 2, the sealing assembly 3 and the driving assembly 4 can be driven to rotate together to adjust the angle between the steel belt 31 and the cylindrical casing.

[0050] Furthermore, a guide rail 13 is provided between the two connecting blocks 12 . The guide rail 13 passes through the slider 15 and has two ends respectively connected to the two connecting blocks 12 , so as to provide guidance for the transmission between the screw rod 14 and the slider 15 .

[0051] In this embodiment, there are two guide rails 13 , and the two guide rails 13 are located on both sides of the screw rod 14 .

[0052] Furthermore, one end of the screw rod 14 passes through the connecting block 12 and is connected to a knob 18 .

[0053] It can be understood that by applying a rotational force to the knob 18 , the screw rod 14 can be driven to rotate.

[0054] In this embodiment, the knob 18 is connected to the screw rod via the nut 108 .

[0055] In this embodiment, both ends of the screw rod 14 are rotatably connected to the connecting block 12 via copper sleeves 104 .

[0056] In this embodiment, the two connection blocks 12 are connected to the top plate 11 by sealing the top plate 102 .

[0057] In this embodiment, a first rotating hole is provided on the rotating block 16, and an inner sleeve 161 is arranged in the first rotating hole. A rotating groove is provided at one end of the sliding block 15 close to the rotating block 16, and a second rotating hole is penetrated through the inner wall of the rotating groove. A rotating shaft 151 is inserted in the second rotating hole. The rotating shaft 151 and the inner sleeve 161 are rotatably matched to realize the rotating connection between the rotating block 16 and the sliding block 15.

[0058] Furthermore, the connecting assembly 1 also includes a cylinder fixing plate 19 , the cylinder fixing plate 19 is connected to the slider 15 , and the cylinder 17 is connected to the cylinder fixing plate 19 .

[0059] In this embodiment, the cylinder fixing plate 19 is connected to the slider 15 via the baffle 109 .

[0060] It can be understood that after the cylinder 17 is connected to the cylinder fixing plate 19, its output end can be connected to any one or more of the rotating block 16, the transmission assembly 2, the sealing assembly 3 and the driving assembly 4 to form a transmission, so that the cylinder 17 can drive the rotating block 16, the transmission assembly 2, the sealing assembly 3 and the driving assembly 4 to rotate relative to the slider 15, that is, the angle between the steel belt 31 and the cylindrical casing can be adjusted.

[0061] In this embodiment, the output end of the cylinder 17 is connected to the driving assembly 4 through a fisheye bearing 107 .

[0062] The working principle of the present invention is as follows: first, the steel belt 31 is heated by the heating block 34 to make the steel belt 31 reach a temperature capable of heat sealing and welding. When the tubular casing is transported to the sealing and welding device by other transport mechanisms, the distance and angle between the steel belt 31 and the tubular casing are adjusted by twisting the knob 18 and controlling the cylinder 17 to advance until the steel belt 31 and the tubular casing are parallel and fit. At this time, the steel belt 31 heat seals and welds the gap on the tubular casing. At the same time, the motor 41 drives the driving sprocket 42 to rotate, and drives the transmission sprocket 43 to rotate through the chain 44, thereby driving the transmission shaft 22 to rotate, and the transmission shaft 22 drives the pulley 32 to rotate, and finally the pulley 32 drives the steel belt 31 to move along with the transmission of the tubular casing, completing the continuous heat sealing and welding of the tubular casing.

[0063] It can be seen from the above embodiments that the present invention can avoid the situation where the welding width is affected by the electrode by heat-sealing the cylindrical casing in the form of a steel belt. When the nylon film is large in size and the product weight is increased, the cylindrical casing can also be well sealed without pinhole leakage or bulging of the bag during disinfection, thereby reducing costs and raw material losses and not affecting the appearance of the seal.

[0064] The present invention is not limited to the embodiments described in the specific implementation manner. Those skilled in the art may derive other implementation manners based on the technical solution of the present invention, which also fall within the technical innovation scope of the present invention.
