Description
Technical Field
[0001] The utility model belongs to the technical field of packaging bag vacuum pumping devices, in particular to a vacuum pumping component. Background Art
[0002] The bag packaging machine is a packaging equipment that integrates multiple functions such as bag loading, unloading, vacuuming, sealing, and bag unloading. Food and other materials can be loaded into the packaging bag through unloading. After loading, the bag will be transported to the vacuuming station, where vacuuming is performed through a vacuum straw and a clamp that keeps the packaging bag relatively fixed.
[0003] In the prior art, a small-caliber flat-mouthed vacuum nozzle is usually inserted into the middle of the bag opening of the packaging bag to perform vacuum extraction. However, when the packaging bag is filled with bulk materials, the air is mainly concentrated on both sides of the bulk materials (that is, the sides of the packaging bag). During the vacuum extraction process, the negative pressure will cause the bag walls on both sides of the packaging bag to fit together to form a seal, especially near the mouth of the vacuum nozzle, where the bag walls are more likely to fit together to form a seal, making it difficult to effectively extract and empty the air in the packaging bag, affecting the vacuum degree and thus the storage time of the material. Utility Model Content
[0004] In view of this, the purpose of the utility model is to provide a vacuum assembly to solve the problem that the air on both sides of the bulk material cannot be sucked away by the flat-mouthed vacuum nozzle when vacuuming the packaging bag.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A vacuum assembly includes a suction nozzle component, wherein the suction nozzle component includes a main body for inserting into a bag opening of a packaging bag, the width of the main body is smaller than and close to the width of the bag opening of the packaging bag, and suction ports are respectively arranged at both ends of the main body in the width direction.
[0007] In a possible implementation, the main body is thick in the middle and thin at both ends in the width direction.
[0008] In a possible implementation, the main body is shuttle-shaped in the width direction.
[0009] In a possible implementation, the main body extends in a depth direction of the packaging bag to have a preset length.
[0010] In a possible implementation, the suction nozzle component further has a suction tube communicated with the suction port.
[0011] In a possible implementation, the two suction ports are respectively connected to the same suction tube through a branch airway formed in the main body.
[0012] In a possible implementation, it also includes clamping members arranged in pairs and a driving mechanism for driving the clamping members to perform separation and combination actions;
[0013] The clamping piece is in the form of an arched structure with an elastically variable span as a whole, and both ends of the clamping piece are respectively provided with clamping portions for clamping the sides of the packaging bag.
[0014] In a possible implementation, the clamping piece is an integral structure.
[0015] In a possible implementation, the clamping part is a sheet metal part formed by bending.
[0016] In a possible implementation, the clamping portion is connected to a resistance-enhancing pad for contacting the packaging bag.
[0017] Compared with the prior art, the utility model has the following beneficial effects:
[0018] The vacuum pumping assembly of the utility model can simultaneously suck out the air mainly concentrated on both sides of the material in the packaging bag through a suction nozzle component whose main body width matches the bag opening of the packaging bag, in cooperation with the suction ports arranged at both ends in the width direction of the suction nozzle component, thereby achieving more effective vacuum pumping and avoiding the problem that the upper part of the packaging bag is easily sealed and the lower part cannot be sucked during the vacuum pumping process.
[0019] Moreover, the main body of the suction nozzle component is thick in the middle and thin at both ends, which can not only adapt to the shape of the bag opening after the block material is loaded, but also support the bag opening, which can play a better sealing role during vacuuming. The suction nozzle component extends in the depth direction of the packaging bag to form a longer length, which can ensure that the suction nozzle component can form an effective seal with the packaging bag when moving forward and backward in the packaging bag, thereby improving the sealing performance of vacuuming and the quality of the bag opening during subsequent sealing and molding.
[0020] At the same time, the suction nozzle component can be conveniently connected to a suction device for vacuuming through a suction tube, and can facilitate air circulation through two branch airways in its main body.
[0021] In addition, when the air on both sides of the bulk material in the packaging bag is effectively sucked through the suction nozzle component, the two clamping parts driven by the driving mechanism to perform the separation and combination action can also simultaneously perform the bag-supporting action on both sides of the packaging bag, so that there can be a larger gap between the two sides of the bulk material with more air and the packaging bag through the bag-supporting action to evacuate air, further avoiding the situation where the inner walls of the two sides of the packaging bag are easily sealed near the suction port during the suction process.

DETAILED DESCRIPTION
[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with specific implementation methods.
[0030] Figure 1 It is a stereoscopic view of a vacuum assembly at a first viewing angle, which mainly shows the main body 11 of the suction nozzle component 1 and the suction pipe 12. Figure 2 The present invention is a stereoscopic view of a vacuum pumping component at a second viewing angle.
[0031] Please refer to Figure 1 and Figure 2 As shown, an embodiment of the present application provides a vacuum extraction component, including a suction nozzle component 1, wherein the suction nozzle component 1 includes a main body 11 for inserting into the bag opening 21 of the packaging bag 2, the width of the main body 11 is smaller than and close to the width of the bag opening 21 of the packaging bag 2, and the main body 11 is respectively provided with suction ports 13 at both ends in the width direction.
[0032] Among them, the suction nozzle component 1 mainly comprises a main body 11 for inserting into the bag opening 21 of the packaging bag 2. The width of the main body 11 is set to be smaller than and close to the width of the bag opening 2, so that the main body 11 can be inserted into the bag opening 21 while the two ends can be extended to the two sides of the packaging bag 2 accordingly, and then the suction ports 13 can be arranged at the two ends of the extended main body 11. The suction ports 13 located on both sides can simultaneously suck the two sides of the block material 4 where most of the air is concentrated, so as to achieve effective vacuuming. Moreover, by sucking on both sides at the same time, the problem that the upper part of the packaging bag 2 is easily sealed during the vacuuming process, resulting in the inability to suck the lower part, can be avoided.
[0033] It can be understood that the size of the main body is based on the bag opening of the packaging bag, that is, the extension direction of the bag opening is the width direction, and accordingly, the size of the main body in the same direction is also the width; of course, this is for the convenience of limiting the description. In other scenarios, the length can also be replaced by the width for description without limitation.
[0034] Through the above-mentioned technical solution, a suction nozzle component 1 whose main body width matches the bag opening 21 of the packaging bag 2 is adopted, and the suction ports 13 arranged at both ends in the width direction thereof are cooperated, so that the air mainly concentrated on both sides of the material in the packaging bag 2 can be sucked simultaneously, thereby achieving more effective vacuuming and avoiding the problem that the upper part of the packaging bag 2 is easily sealed during the vacuuming process, resulting in the inability to suck the lower part.
[0035] After the bulk material 4 is placed in the packaging bag 2, the bag opening 21 will be wide in the middle and narrow at both ends. If the conventional flat-mouthed suction nozzle component 1 is still used, the suction nozzle component 1 will not be able to fully fit with the bag opening 21 and effectively seal.
[0036] In order to solve the above-mentioned problem, in one embodiment, the main body 11 is thick in the middle and thin at both ends in the width direction.
[0037] The main body of the suction nozzle member 1 is thick in the middle and thin at both ends, which can not only match the shape of the bag opening 21 after the block material 4 is loaded, but also support the bag opening 21, and can play a better sealing role when vacuuming. Such a structure can also facilitate the block material 4 to be blocked by the solid part in the middle, so as to move it into place and avoid direct suction of the block material 4.
[0038] On this basis, the main body 11 of such a structure is specifically shuttle-shaped in the width direction. The shuttle-shaped shape makes the main body 11 of the nozzle member 1 have a smooth transition structure from the middle to both ends, so that it can fit more fully with the bag opening 21, further improving the sealing performance during the suction process.
[0039] Furthermore, when the suction nozzle assembly 1 is in use, it needs to move forward and backward relative to the packaging bag 2. In order to ensure that the bag opening 21 can always be supported and sealed during the movement of the suction nozzle assembly 1, the main body 11 extends in the depth direction of the packaging bag 2 to have a preset length. The preset length can be selected and configured according to actual needs, and it is preferably greater than or equal to the distance that the suction nozzle assembly 1 needs to penetrate and retreat in the bag opening 21.
[0040] In this way, by extending the suction nozzle component 1 in the depth direction of the packaging bag 2 to form a longer length, it can be ensured that the suction nozzle component 1 can form an effective seal with the packaging bag 2 when moving forward and backward, thereby improving the vacuum sealing performance and the quality of the bag opening 21 during subsequent sealing and molding.
[0041] In a specific implementation process, the nozzle component 1 further comprises a suction pipe 12 connected to the suction port 13. A suction device such as a vacuum pump can be connected through the suction pipe 12, so that the packaging bag 2 can be vacuumed.
[0042] Figure 3 It is a cross-sectional view of a vacuum assembly, which mainly shows the cross-sectional structure of the main body 11 of the suction nozzle component 1 and the suction pipe 12.
[0043] Please refer to Figure 3 As shown, the two suction ports 13 are respectively connected to the same suction pipe 12 through a branch airway 14 formed in the main body. The two branch airways 14 in the main body can facilitate the circulation of air.
[0044] In some implementation structures of the branch airway 14, it can be set to Figure 3 The bent airway structure shown can also be set as a straight airway structure without limitation. Of course, a connecting port is also provided at the top of the main body 11 of the nozzle member 1, and the connecting port can be convenient for connecting the suction pipe 12 and connecting the two branch airways 14 to the suction pipe 12.
[0045] In the embodiments of the present application, while the air on both sides of the bulk material 4 in the packaging bag 2 is effectively sucked out by the suction nozzle component 1, the packaging bag 2 on both sides of the bulk material 4 where air mainly exists can also be supported by an additional mechanism. The support is achieved by stretching the two sides of the packaging bag 2 tight and straightening them to avoid the areas of the packaging bag 2 on both sides of the bulk material 4 being pressed together to form a seal due to the negative pressure, which makes it difficult to effectively empty and extract the air in the areas of the packaging bag 2 on both sides of the bulk material 4.
[0046] Figure 4This is a schematic diagram of the use of a vacuum assembly when a clamping member 3 and a driving mechanism are provided. The diagram mainly shows the state in which two pairs of clamping members 3 jointly squeeze the two sides of the packaging bag 2 under the clamping action to support the bag to both sides; Figure 5 It is a schematic diagram of the structure of a clamping member 3 of a vacuum assembly, and the figure also shows the movement direction of a pair of clamping members 3 when performing the separation and combination action.
[0047] For example, please refer to Figure 4 and Figure 5 As shown, the additional mechanism is a pair of clamping members 3 and a driving mechanism (not shown in the figure) for driving the clamping members 3 to separate and close; the clamping members 3 are overall in the form of an arched structure with an elastically variable span, and the two ends of the clamping members 3 respectively have clamping portions 31 for clamping the sides of the packaging bag 2.
[0048] The two clamping members 3 are driven by the driving mechanism to separate and close. When clamping, the clamping parts of the two clamping members 3 cooperate to clamp the sides of the packaging bag, and the distance between the clamping parts 31 at both ends of the arch is increased through the elastic deformation of the arch to straighten the packaging bag, so that the two sides of the bulk material 4 with more air can be evacuated by supporting the bag to have a larger distance, further avoiding the situation that the inner walls of the two sides of the packaging bag 2 are easily sealed near the suction port 13 during the suction process. The clamping member 3 with an arch structure can not only facilitate the avoidance of materials, but also facilitate the elastic movement of the clamping parts 31 at both ends along the span direction.
[0049] Specifically, the clamping member 3 is an integrated structure, so that the extrusion can be smoother. The driving mechanism can be a linear driving mechanism, such as a linear driving component such as a cylinder, or it can be an existing mechanism that uses other non-linear motion paths but directly aims to achieve the opening and closing separation and combination action, and is not limited. The driving mechanism can install at least one group of paired clamping members 3 through a mounting arm, such as two pairs arranged longitudinally. A driving mechanism such as a cylinder can install two pairs of clamping members 3 through two symmetrical mounting arms, so that the two pairs of clamping members 3 can be controlled to perform separation and combination actions.
[0050] In addition, the clamping part 3 may be a sheet metal part formed by bending.
[0051] Figure 6 The figure is a schematic diagram of the connection structure between a clamping part of a vacuum assembly and a resistance-enhancing pad.
[0052] In order to increase the friction between the clamping portion 31 and the packaging bag 2, Figure 6As shown, the clamping portion 31 is connected with a resistance-enhancing pad for contacting the packaging bag 2. The resistance-enhancing pad can be made of rubber material and includes a pad portion 51 and a columnar connecting portion 52 connected in one piece. The columnar connecting portion is provided with at least one annular limiting protrusion 53, and the limiting protrusion is limitedly matched with the connecting hole 32 provided on the clamping portion 31, so that the resistance-enhancing pad 5 can be installed by the elastic deformation of the limiting protrusion 53 during disassembly or assembly, and installation or replacement is more convenient.
[0053] The above are only preferred embodiments of the present invention. It should be noted that the above preferred embodiments should not be regarded as limiting the present invention. The protection scope of the present invention should be based on the scope defined by the claims. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the spirit and scope of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
