Description
Technical Field
[0001] The utility model relates to the technical field of vacuum packaging machines, in particular to a heating row of a vacuum packaging machine. Background Art
[0002] When a vacuum packaging machine is used for packaging, the heating row of the vacuum packaging machine heats the packaging bag for sealing. When the existing heating row is powered on for heating, the heating wire will expand and contract thermally. Especially during the contraction process of the heating wire, the middle part of the heating wire will bulge and fold. After being used for a period of time, the bulging and folding parts of the heating wire are prone to breakage, resulting in the need to replace the heating wire. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a heating row of a vacuum packaging machine aiming at the deficiencies of the above-mentioned existing technology.
[0004] To solve the above technical problem, the technical solution adopted by the utility model is:
[0005] A heating row of a vacuum packaging machine includes a heating row base, an installation groove is arranged on the heating row base, a support seat is connected in the installation groove, installation blocks are connected to both sides of the support seat. An insulating cushion plate, a high-temperature adhesive tape, a heating wire and a high-temperature cloth are sequentially arranged above the support seat and the installation blocks. A copper seat is arranged on the side of the installation block, and both ends of the heating wire are fixed on the copper seat through a pressing plate. Upper and lower installation holes are processed in the installation block. A first guide sleeve is arranged in the upper installation hole, a spring is arranged in the first guide sleeve, a first guide post is arranged in the middle of the spring. A second guide sleeve is arranged in the lower installation hole, a linear bearing is connected in the second guide sleeve, and a second guide post passes through the middle of the linear bearing. The ends of the first guide post and the second guide post are connected to the copper seat through screws.
[0006] Further, an installation seat is arranged on the heating row base, an installation groove is processed in the middle of the installation seat, the bottoms of the support seat and the installation blocks are stuck in the installation groove. A connecting seat is arranged on one side of the bottom of the installation block, the connecting seat is stuck in the support seat and locked through a countersunk head screw on the side of the support seat. A long screw passes through the installation seat, and a nut is connected to the long screw to lock the support seat.
[0007] Further, an insulating partition is arranged between the copper seat and the first guide post and the second guide post.
[0008] Further, a first spacer is arranged in the upper installation hole, and a second spacer is arranged in the lower installation hole.
[0009] Further, both sides of the high-temperature cloth are fixed on the support seat, and the high-temperature cloth covers the entire heating wire.
[0010] Compared with the prior art, in a heating row of a vacuum packaging machine of the present utility model, a spring and a linear bearing are arranged in the mounting block. During the heating process of the heating wire, the elastic force of the spring keeps the heating wire taut. When the heating wire cools down, the elastic force of the spring makes the heating wire slowly contract, avoiding the phenomena of the heating wire bulging and folding, and improving the service life of the heating wire.

[0015] Next, the technical solutions in the embodiments of the present utility model will be described clearly and completely.
[0016] As Figures 1 to 3 shown, a heating row of a vacuum packaging machine includes a heating row base 1. An installation groove is provided on the heating row base 1. A support seat 2 is connected in the installation groove. Both sides of the support seat 2 are connected with mounting blocks 3. Among them, a mounting seat is provided on the heating row base 1. An installation groove is machined in the middle of the mounting seat. The bottom of the support seat 2 and the mounting blocks 3 are stuck in the installation groove. A connecting seat 4 is provided on one side of the bottom of the mounting block 3. The connecting seat 4 is stuck in the support seat and locked by a countersunk head screw on the side of the support seat 2. A long screw 5 passes through the mounting seat, and a nut is connected to the long screw 5 to lock the support seat. An insulating cushion plate 6, a high-temperature adhesive tape 7, a heating wire 8 and a high-temperature cloth 9 are sequentially arranged above the support seat 2 and the mounting blocks 3. The two sides of the high-temperature cloth 9 are folded and fixed on the support seat 2. The high-temperature cloth 9 covers the entire heating wire 8.
[0017] A copper seat 10 is arranged on the side of the mounting block 3. Both ends of the heating wire 8 are fixed on the copper seat 10 through a pressure plate 11. Among them, after the pressure plate 11 clamps the heating wire 8, it is locked on the copper seat 10 through mounting screws, springs and gaskets. Upper and lower mounting holes are machined in the mounting block 3. A first guide sleeve 11 is arranged in the upper mounting hole. A spring 12 is arranged in the first guide sleeve 11. A first guide post 13 is arranged in the middle of the spring 12. A second guide sleeve 14 is arranged in the lower mounting hole. Two linear bearings 15 are connected in the second guide sleeve 14. A second guide post 16 passes through the middle of the linear bearings 15. The ends of the first guide post 13 and the second guide post 16 are connected to the copper seat through screws. During the process of the copper seat 10 conducting heat when electrified, the heating wire heats up and expands to become longer. Under the action of the spring, the copper seat 10 slides along the guiding directions of the first guide post 13 and the second guide post 16.
[0018] In order to prevent short - circuit during the electrification of the copper seat 10, an insulating partition 17 is arranged between the copper seat 10 and the first guide post 13 and the second guide post 16. A first spacer 18 is arranged in the upper mounting hole. A second spacer 19 is arranged in the lower mounting hole. The first spacer 18 and the second spacer 19 respectively block the first guide post 13 and the second guide post 16.
