Description

Technical Field

[0001] The utility model relates to a moving device, more specifically, it relates to a moving device for a bottom pasting machine. Background Art

[0002] Currently, existing packaging bags usually need to be glued on the bottom by a bottom gluing machine. Various roller mechanisms are usually used as moving devices to drive the packaging bags to move on the bottom gluing machine so as to be glued and folded. However, when the rollers roll, the packaging bags will generate sliding friction with the frame, and the surface of the packaging bags will be worn, resulting in high bag breakage and scrap rates. Therefore, a moving device for the bottom gluing machine that does not generate sliding friction between the packaging bags and the frame is needed.

[0003] In view of the above reasons, how to prevent the packaging bag from generating sliding friction with the frame is exactly the problem considered in this application. Utility Model Content

[0004] In view of the shortcomings of the prior art, a moving device for a bottom pasting machine is provided, which can prevent the packaging bag from generating sliding friction with the frame during operation.

[0005] To achieve the above-mentioned purpose, the following technical solution is provided: a mobile device for a bottom pasting machine, comprising a frame, two symmetrically arranged beams are fixedly connected to the frame, the beams are connected to a moving mechanism, the beams are also fixedly connected to a rack, the moving mechanism comprises a clamping piece for clamping a packaging bag, a motor is fixedly connected inside the clamping piece, the motor is connected to a transmission shaft rotatably connected to the clamping piece, and the transmission shaft is fixedly connected to a moving gear meshing with the rack.

[0006] In summary, the above technical solution has the following beneficial effects: two symmetrically arranged crossbeams are provided with moving mechanisms, and the clamping members in the moving mechanisms completely cover the side of the packaging bag to avoid direct contact between the packaging bag and the crossbeam, and the two symmetrically arranged clamping members can increase the static friction force on the packaging bag by squeezing to prevent the packaging bag from falling off during movement, and after clamping, the two moving mechanisms can move synchronously on the crossbeam to deliver the packaging bag to various components of the bottom gluing machine. During this process, the packaging bag and the clamping members remain relatively still, so that no friction damage will occur;

[0007] When controlling the movement of the clamping part, it is necessary to control the motor to start, and the motor drives the moving gear to rotate through the transmission shaft, and the moving gear is meshed with the rack, so that the clamping part can be driven to move along the rack direction, and the moving direction of the clamping part can be controlled by controlling the rotation direction of the motor;

[0008] Since rollers are usually used in the prior art to drive the packaging bag to move by rolling, the contact surface between the packaging bag and the crossbeam is constantly moving relative to each other, which will cause friction damage. In the utility model, the packaging bag is clamped by two symmetrically arranged clamping members, so that the packaging bag and the clamping members remain stationary during the movement, while the clamping members move relative to the crossbeam, thereby preventing the contact surface between the packaging bag and the crossbeam from moving relative to each other, thereby achieving the purpose of preventing the packaging bag from generating sliding friction with the frame during operation, thereby preventing friction damage.

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. The same parts are represented by the same reference numerals. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0019] Reference Figure 1-3As shown, a mobile device for a bottom pasting machine includes a frame 1, two symmetrically arranged crossbeams 2 are fixedly connected to the frame 1, a mobile mechanism 3 is connected to the crossbeam 2, a rack 21 is also fixedly connected to the crossbeam 2, the mobile mechanism 3 includes a clamping member 31 for clamping a packaging bag, a motor 32 is fixedly connected inside the clamping member 31, the motor 32 is connected to a transmission shaft 33 rotatably connected to the clamping member 31, and the transmission shaft 33 is fixedly connected to a mobile gear 34 meshing with the rack 21;

[0020] The two symmetrically arranged crossbeams 2 are both provided with moving mechanisms 3, and the clamping members 31 in the moving mechanisms 3 completely cover the side of the packaging bag to prevent the packaging bag from directly contacting the crossbeam 2, and the two symmetrically arranged clamping members 31 can increase the static friction force on the packaging bag by squeezing to prevent the packaging bag from falling off during the movement. After clamping, the two moving mechanisms 3 can move synchronously on the crossbeam 2 to deliver the packaging bag to various components of the bottom gluing machine. During this process, the packaging bag and the clamping members 31 remain relatively still, so no friction damage will occur;

[0021] When controlling the movement of the clamping member 31, it is necessary to control the motor 32 to start, and the motor 32 drives the moving gear 34 to rotate through the transmission shaft 33, and the moving gear 34 is meshed and connected with the rack 21, so that the clamping member 31 can be driven to move along the direction of the rack 21, and the moving direction of the clamping member 31 can be controlled by controlling the rotation direction of the motor 32;

[0022] Since rollers are usually used in the prior art to drive the packaging bag to move by rolling, the contact surface between the packaging bag and the beam 2 is constantly moving relative to each other, which will cause friction damage. In the utility model, the packaging bag is clamped by two symmetrically arranged clamping members 31, so that the packaging bag remains stationary with the clamping members 31 during the movement, while the clamping members 31 move relative to the beam 2, thereby preventing the contact surface between the packaging bag and the beam 2 from moving relative to each other, thereby achieving the purpose of preventing the packaging bag from generating sliding friction with the frame 1 during operation, thereby preventing friction damage.

[0023] Furthermore, the clamping member 31 includes a first fixing plate 311 arranged horizontally and a second fixing plate 312 arranged vertically, the motor 32 is arranged in the first fixing plate 311, and the rack 21 is arranged toward the first fixing plate 311;

[0024] The crossbeam 2 is also fixedly connected with a first guide rail 22 arranged toward the first fixed plate 311, and first grooves 23 are provided on both sides of the first guide rail 22. The first fixed plate 311 is provided with a first moving member 313 slidably connected to the first guide rail 22 at one end away from the second fixed plate 312, and the first moving member 313 is fixedly connected with a first positioning bar 314 accommodated in the first groove 23;

[0025] The crossbeam 2 is also fixedly connected with a second guide rail 24 arranged toward the second fixed plate 312, and second grooves 25 are provided on both sides of the second guide rail 24. The second fixed plate 312 is provided with a second moving member 315 slidably connected to the second guide rail 24 at one end away from the first fixed plate 311, and the second moving member 315 is fixedly connected with a second positioning bar 316 accommodated in the second groove 25;

[0026] The first fixing plate 311 and the second fixing plate 312 can make the clamping member 31 present an "L" shape, and the rack 21 is arranged toward the first fixing plate 311, so that the meshing insertion direction of the moving gear 34 and the rack 21 can be in a vertical direction, thereby preventing the gear teeth of the moving gear 34 from being misaligned due to excessive force caused by gravity, thereby affecting the bottom pasting operation position;

[0027] The first moving member 313 cooperates with the first guide rail 22, and the second moving member 315 cooperates with the second guide rail 24, so that the clamping member 31 can be limited from two directions to prevent movement in a direction perpendicular to the moving direction, and can also share the weight of the clamping member 31, play a supporting role, and prevent the moving gear 34 from rubbing against the crossbeam 2. In addition, the first moving member 313 and the second moving member 315 are both arranged away from the connection between the first fixed plate 311 and the second fixed plate 312, so as to prevent conflicts with the moving gear 34 and the rack 21 as much as possible;

[0028] In order to further prevent the first moving member 313 from detaching from the first guide rail 22 , a first positioning bar 314 is arranged to be accommodated in the first groove 23 , which can achieve a clamping effect. Similarly, a second positioning bar 316 is arranged to be accommodated in the second groove 25 to prevent the second moving member 315 from detaching from the second guide rail 24 .

[0029] Furthermore, the second fixing plate 312 is also fixedly connected to the airbag 4 on the side away from the crossbeam 2;

[0030] The second fixing plate 312 is also fixedly connected to a side away from the cross beam 2 with an elastic positioning member 5 disposed above the airbag 4;

[0031] Since the second fixing plate 312 must be made of a rigid material, if there are protrusions on the surface, the surface of the packaging bag will be damaged, and the fit of the two second fixing plates 312 will be reduced. Therefore, the airbag 4 is provided as a buffer component, which can not only make the packaging bag and the clamping member 31 relatively still through the static friction force generated with the surface of the packaging bag, but also prevent the occurrence of protrusions;

[0032] In addition, since the airbag 4 has a certain volume, the two second fixing plates 312 may burst the airbag 4 if they are too close to each other. Therefore, an elastic positioning member 5 is provided. On the one hand, it can be used to fix the packaging bag near the bottom of an unimportant area, and on the other hand, it can prevent the two second fixing plates 312 from being too close to each other through interference.

[0033] Furthermore, the second fixing plate 312 is provided with an air passage 41 communicating with the airbag 4, the air passage 41 is fixedly connected with an isolation plate 42, the isolation plate 42 is provided with a through hole 43, and the isolation plate 42 is also fixedly connected with a one-way ventilation mechanism 44 for blocking the through hole 43;

[0034] The one-way ventilation mechanism 44 includes two connecting members 45 fixedly connected to the isolation plate 42 and symmetrically arranged, and the connecting members 45 are fixedly connected with elastic gaskets 46 for blocking the through holes 43 and abutting against the isolation plate 42;

[0035] During the pasting operation, a certain amount of gas needs to be maintained in the airbag 4. The one-way ventilation mechanism 44 allows gas to enter and prevents gas from flowing out. When the airbag 4 needs to be filled with gas, the flowing air lifts the elastic gasket 46, and the middle part is deformed toward the inside of the airbag 4. Therefore, the edges of the elastic gasket 46 are away from the isolation plate 42 except for the two ends fixed by the connecting piece 45, so that air can enter the airbag 4.

[0036] Under normal circumstances, when the air inside the airbag 4 wants to flow out, although the flowing air can also impact the elastic gasket 46, the elastic gasket 46 abuts against the isolation plate 42 and cannot be deformed, so the air cannot flow out, thereby preventing gas loss.

[0037] Furthermore, an air pump 6 is provided in the cross beam 2, the air pump 6 is connected to a pipe 61 extending out of the cross beam 2, the pipe 61 is fixedly connected to a plug-in piece 62, the second fixing plate 312 is fixedly connected to a plug-in piece 63 facing one side of the cross beam 2 and covering the air passage 41, and the plug-in piece 63 is provided with a slot 64 for accommodating the plug-in piece 62;

[0038] Since the pipe 61 needs to adapt to the vent 41 and also facilitate the movement of the clamp 31, a connector 63 and a connector plate 62 are set as connecting devices. When the connector plate 62 is inserted into the connector 63, the connector 63 can prevent the gas input from the pipe 61 from leaking, thereby quickly inflating the airbag 4.

[0039] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
