Description

Technical Field

[0001] This utility model relates to a passive wheel assembly for a sealing machine, belonging to the field of sealing machines. Background Technology

[0002] A sealing machine is a machine that seals containers filled with packaging materials. After the product is put into the packaging container, in order to preserve the product, maintain the product quality, and prevent product loss, the packaging container needs to be sealed. This operation is completed on a sealing machine.

[0003] The passive rollers used to install the feeding conveyor belt on existing sealing machines can cause the conveyor belt to deviate after long-term use. Traditionally, the passive rollers are adjusted by mounting bolts to correct the deviation of the conveyor belt. However, this adjustment method is prone to failure due to loose mounting bolts, requiring frequent adjustments, which is not conducive to improving production efficiency and quality. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide a passive wheel assembly for a sealing machine.

[0005] A passive wheel assembly for a sealing machine is fixedly mounted in the material inlet direction of the sealing machine. The passive wheel assembly includes an adjusting seat, on which a passive wheel for conveying packaging bags is mounted. The adjusting seat has through grooves penetrating three sides of the adjusting seat, forming a deformable gap between the grooves. The front-to-back position of the passive wheel is adjusted according to the size of the gap. Adjustment is achieved through the deformable gap of the adjusting seat, eliminating the need for bolt fixing, thereby improving the stability of the passive wheel. This avoids problems such as sealing misalignment and uneven sealing caused by conveyor belt deviation, ensuring sealing quality and improving product packaging consistency. Compared to traditional bolt adjustment methods, the structure is simpler, easier to manufacture and install, and applicable to conveyor belt systems of different sizes, offering greater adaptability.

[0006] Preferably, the adjusting seat has an opening on one side between opposite sides, and adjusting holes are provided on both sides of the opening. Adjusting bolts, whose ends connect to the sealing machine, are installed in the adjusting holes. The size of the gap is adjusted by the tightness of the connection between the adjusting bolts and the sealing machine. The opening on the opposite sides of the adjusting seat, and the adjusting holes on both sides of the opening, make the deformation adjustment of the adjusting seat more flexible. By adjusting the tightness of the adjusting bolts, the size of the gap can be precisely controlled, thereby adjusting the front-to-back position of the driven wheel and improving its adaptability.

[0007] Furthermore, the adjustment holes include a first adjustment hole and a second adjustment hole located on the side of the adjustment seat where the driven wheel is mounted, and a third adjustment hole located on the adjustment seat away from the driven wheel and corresponding to the second adjustment hole. Users can more conveniently adjust the position of the driven wheel according to actual operating conditions without frequent disassembly and assembly of components, reducing maintenance difficulty.

[0008] Furthermore, the adjusting bolts are located in the first adjusting hole, the second adjusting hole, and the third adjusting hole, respectively. The gap size is adjusted by adjusting the upper and lower adjusting bolts. One end of the adjusting bolt is fixed, and the other end is used for adjustment. The tightness of the connection between the adjusting bolt and the sealing machine is adjusted to change the gap size. The adjustment method is simple and quick.

[0009] Furthermore, a connecting groove, which is arc-shaped, is provided on the inner wall of the through groove opposite to the opening. The arc-shaped connecting groove on the inner wall of the through groove opposite the opening allows the adjusting seat to deform along the arc-shaped groove when under force adjustment, ensuring that the driven wheel can move more smoothly and accurately during adjustment, thus achieving a more flexible adjustment effect. Because the connecting groove is arc-shaped, the force on the adjusting bolt is distributed more evenly across the entire adjusting structure of the adjusting seat, reducing local stress concentration, thereby reducing wear on the adjusting bolt and improving the service life of the overall structure.

[0010] Furthermore, the diameter of the connecting groove is larger than the spacing of the through grooves. Because the connecting groove diameter is larger than the through groove spacing, the adjusting seat can provide greater deformation space during adjustment, allowing for a wider adjustment range of the driven wheel, adapting to conveyor belts with different tensions, and improving the compatibility of the sealing machine. The larger diameter of the connecting groove also allows for a wider adjustment range of the driven wheel, accommodating the conveying needs of packaging bags of different specifications and thicknesses, improving the applicability of the sealing machine, and making it suitable for the production of more types of product packaging.

[0011] Preferably, the sealing machine has a connecting hole, and the bottom of the adjusting seat has several fixing holes. The adjusting seat is fixed to the sealing machine by bolts connected to the connecting hole and the fixing hole. By providing several fixing holes at the bottom of the adjusting seat and fixing it to the connecting hole of the sealing machine with bolts, the adjusting seat can be more firmly installed on the sealing machine, preventing it from loosening or shifting due to vibration or force during long-term operation, thus improving the stability of the feeding system. Since the adjusting seat is fixed by bolts through the fixing holes, it can remain stable after adjusting the position of the driven wheel and will not shift due to external forces, thereby ensuring that the conveyor belt maintains a good feeding trajectory during operation, improving conveying accuracy and sealing quality.

[0012] Preferably, a fixed shaft is fixed on the adjusting seat, and a rotating bearing is sleeved on the fixed shaft. The driven wheel is sleeved outside the rotating bearing. By fixing the fixed shaft on the adjusting seat and sleeved the rotating bearing on the fixed shaft, the driven wheel can rotate more smoothly. The use of the rotating bearing ensures the smooth rotation of the driven wheel, avoids conveyor belt deviation caused by the driven wheel shaking or uneven rotation, improves conveying accuracy, ensures accurate conveying position of the packaging bag, and thus improves sealing quality.

[0013] The beneficial effects of this utility model are as follows: the adjustment is made by adjusting the deformable gap of the adjustment seat, without relying on bolts for fixing and adjustment, thereby improving the stability of the passive wheel, avoiding problems such as misalignment and uneven sealing caused by conveyor belt deviation, ensuring sealing quality, improving product packaging consistency, and compared with the traditional bolt adjustment method, the structure is simpler, easier to manufacture and install, and applicable to conveyor belt systems of different sizes, with stronger adaptability.

[0024] like Figure 1-5 The diagram illustrates an embodiment of a passive wheel assembly for a sealing machine according to this invention. Fixed in the material inlet direction of the sealing machine 1, the passive wheel assembly includes an adjusting seat 2. The adjusting seat 2 has a passive wheel 24 for conveying packaging bags. The adjusting seat 2 has through grooves 21 penetrating its three sides, forming deformable gaps 211 between the grooves. The front-to-back position of the passive wheel 24 is adjusted according to the size of these gaps 211. Adjustment is achieved through the deformable gaps 211 of the adjusting seat 2, eliminating the need for bolt fixing. This improves the stability of the passive wheel 24, preventing sealing misalignment and uneven sealing caused by conveyor belt deviation, ensuring sealing quality, and improving product packaging consistency. Compared to traditional bolt adjustment methods, this structure is simpler, easier to manufacture and install, and suitable for conveyor belt systems of different sizes, offering greater adaptability.

[0025] An opening 212 is provided on the side of the adjusting seat 2 between opposite sides. Adjusting holes are provided on both sides of the opening 212, and adjusting bolts 214, whose ends are connected to the sealing machine 1, are installed in the adjusting holes. The size of the gap 211 is adjusted by the tightness of the connection between the adjusting bolts 214 and the sealing machine 1. The opening 212 on the opposite side of the adjusting seat 2 and the adjusting holes on both sides of the opening 212 make the deformation adjustment of the adjusting seat 2 more flexible. By adjusting the tightness of the adjusting bolts 214, the size of the gap 211 can be precisely controlled, thereby adjusting the front and rear position of the driven wheel 24 and improving the adaptability of the driven wheel 24.

[0026] The adjustment holes include a first adjustment hole 217 and a second adjustment hole 218 located on the side of the adjusting seat 2 where the driven wheel 24 is mounted, and a third adjustment hole 219 located on the adjusting seat 2 away from the driven wheel 24 and corresponding to the second adjustment hole 218. Users can more conveniently adjust the position of the driven wheel 24 according to actual operating conditions without frequent disassembly and assembly of components, thus reducing maintenance difficulty.

[0027] The adjusting bolts 214 are located in the first adjusting hole 217, the second adjusting hole 218, and the third adjusting hole 219, respectively. The size of the gap 211 is adjusted by adjusting the upper and lower adjusting bolts 214. One end of the adjusting bolt 214 is fixed, and the other end is used for adjustment. The tightness of the connection between the adjusting bolt 214 and the sealing machine 1 is adjusted to change the size of the gap 211. The adjustment method is simple and quick. The first adjusting hole 217 and the third adjusting hole 219 have threads. By tightening or loosening the adjusting bolts 214, the driven wheel 24 can be adjusted, causing the gap 211 between the adjusting seats 2 to change.

[0028] A connecting groove 215, which is arc-shaped, is provided on the inner wall of the through groove 21 opposite to the opening 212. The arc-shaped connecting groove 215 on the inner wall of the through groove 21 opposite to the opening 212 allows the adjusting seat 2 to deform along the arc-shaped groove when under force adjustment, ensuring that the driven wheel 24 can move more smoothly and accurately during adjustment, thus achieving a more flexible adjustment effect. Because the connecting groove 215 is arc-shaped, the force on the adjusting bolt 214 is more evenly distributed across the entire adjusting structure of the adjusting seat 2, reducing local stress concentration, thereby reducing the wear of the adjusting bolt 214 and improving the service life of the overall structure.

[0029] The diameter of the connecting groove 215 is larger than the spacing of the through grooves 21. Because the diameter of the connecting groove 215 is larger than the spacing of the through grooves 21, the adjusting seat 2 can provide greater deformation space during adjustment, allowing the driven wheel 24 to have a wider adjustment range, adapting to conveyor belts with different tensions and improving the compatibility of the sealing machine 1. The larger diameter of the connecting groove 215 also allows for a wider adjustment range of the driven wheel 24, accommodating the conveying needs of packaging bags of different specifications and thicknesses, thus improving the applicability of the sealing machine 1 and making it suitable for the production of more types of product packaging.

[0030] The sealing machine 1 is provided with a connecting hole 11, and the bottom of the adjusting seat 2 is provided with several fixing holes 216. The adjusting seat 2 is fixed to the sealing machine 1 by bolts connected to the connecting hole 11 and the fixing holes 216. By providing several fixing holes 216 at the bottom of the adjusting seat 2 and fixing it to the connecting hole 11 of the sealing machine 1 with bolts, the adjusting seat 2 can be more firmly installed on the sealing machine 1, preventing the adjusting seat 2 from loosening or shifting due to vibration or force during long-term operation, thus improving the stability of the feeding system. Since the adjusting seat 2 is fixed by bolts through the fixing holes 216, it can remain stable after adjusting the position of the driven wheel 24 and will not shift due to external forces, thereby ensuring that the conveyor belt always maintains a good feeding trajectory during operation, improving conveying accuracy and sealing quality.

[0031] A fixed shaft 22 is fixed on the adjusting seat 2, and a rotating bearing 23 is sleeved on the fixed shaft 22. The driven wheel 24 is sleeved on the outside of the rotating bearing 23. By fixing the fixed shaft 22 on the adjusting seat 2 and sleeved the rotating bearing 23 on the fixed shaft 22, the driven wheel 24 can rotate more smoothly. The use of the rotating bearing 23 ensures the smooth rotation of the driven wheel 24, avoids the conveyor belt from running off-center due to the wobbling or uneven rotation of the driven wheel 24, improves the conveying accuracy, ensures the accurate conveying position of the packaging bag, and thus improves the sealing quality.

[0032] When the conveyor belt shifts inward, loosen the adjusting bolts 214 in the second adjusting hole 218 and the third adjusting hole 219, and tighten the adjusting bolts 214 in the first adjusting hole 217.

[0033] When the conveyor belt shifts outward, tighten the adjusting bolts 214 in the second adjusting hole 218 and the third adjusting hole 219, and loosen the adjusting bolts 214 in the first adjusting hole 217.

[0034] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall still fall within the scope of the present utility model.
