Description

TECHNICAL FIELD

[0001] The utility model relates to a transverse sealing technology field, concretely is a transverse sealing mechanism. BACKGROUND

[0002] As a key process of continuous packaging machine, transverse sealing is a pivotal link in the whole packaging process. It not only determines the integrity of the packaging product, but also affects the subsequent packaging conveying, stacking and other operations. After the packaging material is formed into a product packaging container and filled with products, transverse sealing rapidly intervenes to close the transverse opening of the packaging, completes the key transformation from "open container" to "sealed packaging", and provides a reliable protective barrier for the products, enabling the products to safely enter the logistics and sales channels.

[0003] In the transverse sealing link of the continuous packaging machine, the current technical scheme relies on the cooperation of the two actions of swinging and up-down sliding to ensure that the opening and closing of the transverse sealing part accurately match the operation rhythm of the whole machine.

[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, specific details such as specific system structures, technologies and the like are given in the following description for the purpose of illustration but not for the purpose of limitation, so that the embodiments of the utility model can be thoroughly understood. However, those skilled in the art should know that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits and methods are omitted to avoid unnecessary details that hinder the description of the utility model. Figure 1 to the drawings Figure 3 It can be known that the transversal sealing mechanism mainly comprises the following parts or components: the fixed plate 10, the second rotating shaft 13, the mounting plate 131, the first ironing block 14 and the second ironing block 15.

[0033] In the utility model, two first rotating shafts 11 are arranged in parallel on the fixed plate 10, and the first drive source 12 drives the two first rotating shafts 11 to rotate in opposite directions through the connecting assembly 20; the first ends of the two second rotating shafts 13 are eccentrically fixed on the first ends of the two first rotating shafts 11; the two mounting plates 131 are fixed on the second ends of the two second rotating shafts 13, and the two mounting plates 131 are fixed with the two clamping plate seats 132, and the two clamping plate seats 132 are coaxial with the two second rotating shafts 13; the first ironing block 14 and the second ironing block 15 are fixed on the two clamping plate seats 132 through the first mounting assembly 30 and the second mounting assembly 40, and when the two first rotating shafts 11 drive the two second rotating shafts 13, the two mounting plates 131 and the two clamping plate seats 132 to rotate eccentrically, the first ironing block 14 and the second ironing block 15 are driven to move close to or away from each other through the first mounting assembly 30 and the second mounting assembly 40.

[0034] Specifically, the first drive source 12 is a motor.

[0035] Specifically, the two clamping plate seats 132 move synchronously when running.

[0036] As an embodiment, the drawings attached to the specification Figure 2 It can be seen that the connecting assembly 20 comprises two first synchronous wheels 21, which are respectively fixed on the second ends of the two first rotating shafts 11; the first end of the synchronous belt 23 is in meshing connection with the second synchronous wheel 22 on the first driving source 12, and the second end is in meshing connection with one of the first synchronous wheels 21, and the outer surface of the lower half of the synchronous belt 23 is in meshing connection with the other first synchronous wheel 21.

[0037] When the first driving source 12 rotates clockwise, the second synchronous wheel 22 rotates clockwise, driving the synchronous belt 23 to move. The synchronous belt 23 drives the first synchronous wheel 21 connected thereto to rotate clockwise, so that the first rotating shaft 11 rotates clockwise; and the lower half of the synchronous belt 23 drives the other first synchronous wheel 21 to rotate counterclockwise, driving the second rotating shaft 11 to rotate counterclockwise. This realizes uniform and stable distribution of the power of the first driving source 12 to the two first rotating shafts 11, and provides starting power for the eccentric movement of the subsequent second rotating shaft 13 and the final block to realize the horizontal sealing action.

[0038] Specifically, the inner rotation of the synchronous belt 23 between the two first synchronous wheels 21 is provided with a tensioning wheel 24, which is in meshing connection with the inner surface of the lower half of the synchronous belt 23.

[0039] When the first driving source 12 starts and drives the second synchronous wheel 22 to rotate, the synchronous belt 23 starts to move, thereby driving the two first synchronous wheels 21 to rotate. In this process, the tensioning wheel 24 rotates with the movement of the synchronous belt 23, and it remains in meshing connection with the inner surface of the lower half of the synchronous belt 23 to adjust the tension of the synchronous belt 23.

[0040] As an embodiment, the drawings attached to the specification Figure 3It can be seen that the first mounting assembly 30 comprises a first hot air seat 31 arranged on one side of the corresponding clamping plate seat 132, the first end of the first hot air seat 31 is connected to the corresponding clamping plate seat 132 through a buffer assembly, the second end of the first hot air seat 31 is provided with a first recess (not marked in the figure), the first end of the first ironing block 14 is fixedly arranged in the first recess, and the second end of the first ironing block 14 extends out of the first recess. The second mounting assembly 40 comprises a second hot air seat 41 arranged opposite to the first hot air seat 31, the first end of the second hot air seat 41 is connected to the corresponding clamping plate seat 132 through an adjusting assembly, the second end of the second hot air seat 41 is provided with a second recess (not marked in the figure), the first end of the second ironing block 15 is fixedly arranged in the second recess, and the second end of the second ironing block 15 extends out of the second recess. The buffer assembly comprises a first buffer plate 32 fixedly arranged on the corresponding clamping plate seat 132, a second buffer plate 33 arranged between the first buffer plate 32 and the first hot air seat 31, the second buffer plate 33 is fixedly connected to the first end of the first hot air seat 31, an optical shaft 321 is fixedly arranged on the first buffer plate 32, the free end of the optical shaft 321 is slidingly connected to the second buffer plate 33 and penetrates through the second buffer plate 33, and a spring 34 is fixedly arranged between the first buffer plate 32 and the second buffer plate 33. The adjusting assembly comprises a first adjusting plate 42 fixedly arranged on the corresponding clamping plate seat 132, a second adjusting plate 43 arranged between the first adjusting plate 42 and the second hot air seat 41, the second adjusting plate 43 is fixedly connected to the first end of the second hot air seat 41, and the second adjusting plate 43 is connected to the first adjusting plate 42 through a plurality of bolts 44.

[0041] In the transverse sealing process, when the first ironing block 14 contacts the packaging material, the equipment may be vibrated or damaged due to instantaneous impact force, at this time, the buffer assembly plays a role, the optical shaft 321 slides in the second buffer plate 33, and the spring 34 is compressed, the spring 34 is used to absorb the impact force by elastic deformation, the influence of vibration on other parts of the equipment is reduced, and the first ironing block 14 stably seals the packaging material. In actual production, due to differences in the thickness and material of the packaging material, it is necessary to adjust the relative position between the second ironing block 15 and the first ironing block 14 to achieve the best transverse sealing effect. At this time, by loosening or tightening the bolts 44, the relative position between the second adjusting plate 43 and the first adjusting plate 42 is changed, so that the second hot air seat 41 and the second ironing block 15 are adjusted in position, the transverse sealing parameters are optimized, and the transverse sealing requirements of different packaging materials are met.

[0042] The buffer assembly of the first mounting assembly 30 ensures the stability of the first ironing block 14 during transverse sealing, reduces the adverse effects of impact force, and the adjusting assembly of the second mounting assembly 40 gives the second ironing block 15 adjustability, so that the equipment can adapt to diversified packaging materials. The two cooperate with each other to provide a solid guarantee for the efficient and accurate operation of the continuous packaging machine transverse sealing technology.

[0044] The sliding rail 134 provides precise movement guidance for the sliding block 133 in sliding connection therewith. When the packaging machine is running, the mounting plate 131 and the related components will move due to the eccentric movement of the second rotating shaft 13 driven by the first rotating shaft 11, at this time, the sliding block 133 slides along the sliding rail 134, which can ensure that the first mounting assembly 30 and the second mounting assembly 40 strictly follow the predetermined trajectory during movement, avoiding deviation or shaking.

[0045] And the sliding rail 134 can ensure that the first sealing block 14 and the second sealing block 15 coincide at the heat-sealed material, and keep the pressure stable.
