[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Example

[0028] This embodiment discloses an automatic sealing device for food bags, the overall structure of which is as follows: Figure 1 As shown, it includes a conveyor belt 1, a workbench 2 set on one side of the conveyor belt 1, a hot-press sealing mechanism 3 set on the workbench 2, and a stop alignment component 4 that plays the role of sealing alignment.

[0029] The hot-press sealing mechanism 3 includes an upper hot-press strip 309 and a lower hot-press strip 308 aligned vertically. The upper hot-press strip 309 and the lower hot-press strip 308 are metal heating plates with built-in electric heating wires. The food bag to be sealed is clamped by the upper hot-press strip 309 and the lower hot-press strip 308 to achieve hot-press sealing.

[0030] The upper hot press bar 309 is supported by the upper drive mechanism; the lower hot press bar 308 is installed on the table surface 21 of the workbench 2 for support.

[0031] When performing heat sealing of food bags, the end of the food bag to be sealed is placed between the upper heat sealing strip 309 and the lower heat sealing strip 308 by manual operation. However, due to the lack of a limiting alignment structure on the rear side of the upper and lower heat sealing strips, the manual placement will result in uneven placement and skewing. As a result, the heat sealing area will be a skewed line. Based on this, the automatic food bag sealing device disclosed in this embodiment further installs a stop alignment component 4 on the table surface 21 of the workbench 2.

[0032] like Figure 2 and Figure 3 As shown, the gear alignment piece 4 is located behind the lower hot press strip 308, and the setting height of the gear alignment piece 4 needs to be higher than the setting height of the lower hot press strip 308.

[0033] For ease of description, the main body of the baffle alignment component 4 is named baffle body 41. The baffle body 41 is vertically distributed on the workbench surface 21, and the setting height of the baffle body 41 is higher than the setting height of the lower hot pressing strip 308. Based on the part of the baffle body 41 that is higher than the lower hot pressing strip 308, an alignment groove 42 is provided on the front side of the higher part.

[0034] The alignment groove 42 is a narrow groove, mainly used for the insertion of the food bag on the side to be sealed. Under the guidance of the alignment groove 42, the food bag can be aligned and placed between the upper heat sealing strip 309 and the lower heat sealing strip 308, which effectively reduces the occurrence of food bag misalignment, thereby helping to form a straight sealing heat sealing line.

[0035] Additionally, it should be noted that the conveyor belt 1 on one side of the hot-press sealing mechanism 3 is mainly for the purpose of facilitating the transfer of the sealed food and food bags to the next process.

[0036] Therefore, it can be seen that for the automatic sealing device for food bags disclosed in this embodiment, a stop alignment member 4 is added to the rear side of the lower hot pressing strip 308. Under the guidance of the alignment groove 42 of the stop alignment member 4, the end of the food bag to be sealed is placed between the upper hot pressing strip 309 and the lower hot pressing strip 308 without being crooked, thereby obtaining a neat sealing line and having the technical advantage of improving sealing quality.

[0037] Implementation 2

[0038] This embodiment discloses an automatic sealing device for food bags. Based on the structure disclosed in Embodiment 1, to ensure that the end of the food bag to be sealed can more accurately enter the alignment groove 42 of the stop alignment member 4, such as... Figure 3 and Figure 5 As shown, the baffle body 41 of the gear alignment component 4 is extended to one end so that the length of the baffle body 41 is greater than the length of the lower hot pressing strip 308.

[0039] One end of the extended stop alignment member 4 also has an alignment groove 42, and based on this, guide rollers 43 with vertical spacing are installed in the alignment groove 42.

[0040] The guide rollers 43 are spaced apart vertically, allowing the end of the food bag to be sealed to be inserted through the gap between the upper and lower guide rollers 43. Under the guidance of the guide rollers 43, the end of the food bag to be sealed can enter the alignment groove 42 more smoothly.

[0041] Therefore, in the automatic sealing device for food bags disclosed in this embodiment, the stop alignment member 4 extends out from one end, and a guide roller 43 is provided in the alignment groove 42 of the extended stop alignment member 4. By utilizing the guiding rolling action of the guide roller 43, the food bag can enter the alignment groove 42 more smoothly and accurately. Under the guiding action of the alignment groove 42, the occurrence of food bag skewing is effectively reduced, thereby making the sealing of the upper and lower heat pressing strips more neat and improving the sealing quality of the sealing device. Example

[0042] This embodiment discloses an automatic sealing device for food bags. Based on the structure of the automatic sealing device for food bags disclosed in Embodiment 1, the structure of the heat-sealing mechanism 3 is further defined.

[0043] First Figure 2 As shown, the hot-press sealing mechanism 3 also includes a support member 301;

[0044] There are two sets of support members 301. The two sets of support members 301 are fixedly installed on the table surface 21 of the workbench 2 and together support the fixed platform 302.

[0045] Based on the fixed platform 302, a linear motor 303 is set up. The linear motor 303 serves as the power drive mechanism for the upper heat-pressing strip 309. The connection and assembly with the upper heat-pressing strip 309 are achieved through the moving platform 305 and the carrier 306.

[0046] First, a moving platform 305 is connected to the output end of a linear motor 303. Second, a carrier 306 is assembled on the moving platform 305 through shock-absorbing connectors 310 at both ends. Third, an upper heat-pressing strip 309 is fixedly installed below the carrier 306.

[0047] Therefore, the linear motor 303 drives the moving platform 305 to move up and down, which in turn drives the upper heating strip 309 on the carrier 306 to move up and down. When the food bag is placed between the upper and lower metal heating strips, the pressure required for sealing can be applied.

[0048] Preferably, to improve the stability of the vertical movement of the mobile platform 305, a guide sleeve 311 is also provided on the fixed platform 302. The guide sleeve 311 is distributed on the left and right sides of the linear motor 303, and a guide post 304 is slidably installed inside the guide sleeve 311, which is connected to the mobile platform 305. Thus, through the guiding cooperation between the guide post and the guide sleeve, the vertical movement of the mobile platform 305 is provided with guiding support.

[0049] Furthermore, the shock-absorbing connector 310 specifically includes a connecting screw and a shock-absorbing spring. The shock-absorbing spring is sleeved on the connecting screw and positioned between the moving platform 305 and the carrier 306. The connecting screw is locked to the moving platform 305 at one end and to the carrier 306 at the other end. Thus, the shock-absorbing spring provides a damping effect when the upper hot pressing strip 309 presses down on the lower hot pressing strip 308.

[0050] Furthermore, such as Figure 4As shown, based on the width limitation of the support member 306 that supports the upper hot pressing strip 309, in order to ensure that the setting of the baffle body 4 of the baffle 4 does not affect the hot pressing of the upper and lower hot pressing strips, the setting height of the baffle body 41 of the baffle 4 is higher than the setting height of the lower hot pressing strip 308, while the setting height of the baffle body 41 of the baffle 4 is less than the sum of the heights of the lower hot pressing strip 308 and the upper hot pressing strip 309. Thus, it does not affect the downward movement of the upper hot pressing strip 309 and its tight fit with the lower hot pressing strip 308.

[0051] In addition, a positioning block 307 is fixed on the front side of the lower hot pressing strip 308 to provide reinforcement and support.

[0052] In summary, the automatic food bag sealing device disclosed in this utility model involves a worker inserting the end of the food bag to be sealed into the alignment groove 42 of the alignment member 4 along the gap of the guide roller 43 during the sealing process. Based on the guiding effect of the alignment groove 42, the food bag is positioned neatly and without skewing between the upper and lower heating strips 309 and 308. Once the end of the food bag to be sealed is completely positioned between the upper and lower heating strips, the linear motor 303 provides driving force, causing the two heating strips to adhere and apply pressure. This allows the heated upper and lower heating strips 309 and 308 to automatically seal the food bag. Because the skewing of the food bag is improved, the resulting sealing strip area is more uniform, resulting in a better sealing effect for this automatic food bag sealing device.

[0053] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
