Description

Technical Field

[0001] The utility model relates to the technical field of wrapping machines, in particular to a discharging mechanism and a wrapping machine. Background Art

[0002] At present, the transparent film three-dimensional packaging machine is an automatic packaging equipment suitable for medicine boxes, card boxes, cosmetic boxes and other packaging boxes. Its working process is the pushing of the packed box, the transmission of the packaging film, the wrapping of the packed box and the packaging film, the ironing of the wrapping interface, the heat dissipation and the discharge of the material. The transparent film three-dimensional packaging machine is mainly suitable for the automatic outer packaging of single or multiple pieces of various box-type items in the industries of medicine, food, health products, tea, cosmetics, gifts, stationery, audio-visual products, etc. After the product is heat-sealed, it adopts a passive discharge method. When the machine is stopped, there is no subsequent feeding and advancement, so the package parked on the machine cannot be automatically removed, and manual material removal will easily cause burns.

[0003] In the prior art, there is a case where the passive discharging cannot be automatically discharged when the machine stops, such as a wrapping discharging mechanism of a transparent film three-dimensional packaging machine with patent number CN211108384U; the tail material is transported in the form of a conveyor belt, which requires a certain space in the length direction, but is not applicable to the situation where passive discharging is required in the limited space at the end of the heat sealing station. Utility Model Content

[0004] The purpose of the utility model is to provide a discharging mechanism and a wrapping machine, which solves the problem of how to automatically discharge materials when the space at the passive discharging end of the wrapping machine is limited.

[0005] The utility model is a discharging mechanism realized in this way, comprising a linear driving member, a pushing member and a guiding member, wherein the linear driving member is connected to the pushing member, the driving direction of the linear driving member is consistent with the discharging direction, the guiding member comprises an avoidance section and a pushing section arranged in sequence along the discharging direction, the avoidance section is arranged obliquely along the discharging direction, and the linear driving member can drive the pushing member to move along the avoidance section and the pushing section.

[0006] The next material enters between the materials, pushing the material at the end to be discharged, and passive discharging is performed; in the process of passive discharging, the linear drive is connected to the pusher, and the avoidance section is inclined along the discharging direction. When the pusher moves along the inclined avoidance section, the height of the pusher can be adjusted, so that when the pusher slides in the avoidance section to a height that is not within the range of the material, the avoidance effect is achieved; when there is no next material entering, the tailings will be left in the waiting area for discharging. If it is inconvenient to take it manually and there are safety risks The utility model is connected with the pushing member through a linear drive when the passive discharging cannot complete the discharging of the tail material. The linear drive drives the pushing member to move along the avoidance section of the guide member to the pushing section. At this time, the pushing member can move to the end of the tail material, and move along the discharging direction through the linear drive, driving the pushing member to push the tail material out from the end of the tail material to complete the pushing. The utility model has only one linear drive member, which is matched with the guide member with the avoidance section and the pushing section, so that the pushing member can push the tail material out without interfering with the passive discharging, and at the same time, the number of parts is small and the space occupied is small.

[0007] A further technical solution of the utility model is that the pushing member can slide along the avoidance section to avoid material discharge.

[0008] The avoidance section is inclined, and when the pusher moves along the inclined avoidance section, the height of the pusher can be adjusted, so that when the material is discharged passively, the avoidance effect is achieved when the pusher slides in the avoidance section to a height that is not within the range of the material.

[0009] A further technical solution of the utility model is that the pushing section is consistent with the discharging direction, and the pushing piece slides along the pushing section to move the material along the discharging direction.

[0010] The pushing section is consistent with the discharging direction. When the pushing piece moves along the pushing section, the pushing piece moves along the discharging direction to discharge the tail material smoothly.

[0011] A further technical solution of the utility model is that the material pushing member is elastically rotatably connected to the linear driving member.

[0012] When the pusher slides along the guide to avoid and push materials, the height of the pusher is different. In order to achieve the avoidance and pushing of the pusher, the pusher is designed to be a rotatable structure so that the angle between the pusher and the linear drive can be adjusted. In order to further ensure the stability of the pusher, the space between the pusher and the linear drive is designed to be elastic and rotatable.

[0013] A further technical solution of the utility model is: the pushing member includes a pushing part which can be perpendicular to the discharging direction and a connecting part for connecting the pushing part with the output end of the linear driving member, the pushing part moves along the guide member, and the connecting part is provided with a roller which is slidably connected to the guide member.

[0014] The connecting part is used to connect the pushing part and the linear driving part, so that the pushing part is perpendicular to the discharging direction when moving along the pushing section, which is convenient for pushing out the tail material; a roller slidably connected to the guide part is provided on the connecting part, so that the pushing part reduces wear when moving along the guide part.

[0015] A further technical solution of the utility model is that: the guide member is provided with a slide groove for the pusher to pass through.

[0016] The pusher slides through the slide groove and the guide member. When the pusher moves along the slide groove, the height position of the pusher can be changed, thereby achieving avoidance and pushing.

[0017] A further technical solution of the utility model is: the pushing member is placed above the linear driving member, and the pushing member is connected to the linear driving output end through an L-shaped connecting member.

[0018] The pusher is above the linear drive, which can effectively save space.

[0019] The utility model also provides a wrapping machine, including a material platform, a heat sealing mechanism, a transfer mechanism and a discharging station, wherein the transfer mechanism is used to move the material on the material platform to the heat sealing mechanism, the discharging station is arranged on the side of the heat sealing mechanism opposite to the material platform, and the heat sealing mechanism is provided with the discharging mechanism.

[0020] The wrapped materials are transported to the material platform, and the materials are moved along the heat sealing mechanism through the transfer mechanism to complete the heat sealing of the materials. The heat-sealed materials are discharged along the discharging station under the thrust of the next material entering. When the last material enters the waiting discharging area, passive discharging cannot be achieved because no material enters. The utility model pushes the tailings to the discharging station through the provided discharging mechanism to complete the discharging of the tailings.

[0021] A further technical solution of the utility model is that a heat dissipation section is provided at the output end of the heat sealing mechanism, and the discharging mechanism is placed below the heat dissipation section.

[0022] After the heat sealing is completed, the material enters the heat dissipation section at the tail of the heat sealing mechanism. Before the next material comes, the current material stays on the heat dissipation section to achieve heat dissipation; when there is no next material coming, the last material will stay in the heat dissipation section to avoid burns and other safety issues caused by manual handling. The utility model sets a discharging mechanism below the heat dissipation section. Since the heat dissipation section is short, the problem of limited space below needs to be considered when designing the discharging mechanism. The tail material processing mechanism set in the utility model can achieve material pushing and avoidance through a driving and guiding member, with fewer parts and less space occupation.

[0023] The beneficial effects of the utility model are as follows: the material is pushed out of the end by the entry of the next material, and passive discharging is performed; in the process of passive discharging, the linear drive is connected with the pushing piece, and the avoidance section is inclined along the discharging direction. When the pushing piece moves along the inclined avoidance section, the height of the pushing piece can be adjusted, so that when the material is passively discharged, the pushing piece slides in the avoidance section to a height that is not within the range of the material, so the avoidance effect is achieved; when there is no next material entering, the tail material will be left in the waiting discharging area, and it is inconvenient and difficult to take it manually. There are safety risks. When passive discharging cannot complete the tail material discharging, the utility model is connected to the pushing member through a linear drive. The linear drive drives the pushing member to move along the avoidance section of the guide member to the pushing section. At this time, the pushing member can move to the end of the tail material, and move along the discharging direction through the linear drive, driving the pushing member to push the tail material out from the end of the tail material to complete the pushing. The utility model has only one linear drive member, which is combined with a guide member with an avoidance section and a pushing section, which can meet the requirement of the pushing member to push the tail material out without interfering with passive discharging. At the same time, it has few parts and occupies little space. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Embodiment 1:

[0035] Figure 1-5 A discharging mechanism is shown, including a linear driving member 51, a pushing member 52 and a guide member 53. The linear driving member 51 is connected to the pushing member 52. The driving direction of the linear driving member 51 is consistent with the discharging direction. The guide member 53 includes an avoidance section 54 and a pushing section 55 arranged in sequence along the discharging direction. The avoidance section 54 is inclined along the discharging direction. The linear driving member 51 can drive the pushing member 52 to move along the avoidance section 54 and the pushing section 55.

[0036] In this embodiment, the pushing member 52 can slide along the avoiding section 54 to avoid material discharge.

[0037] In this embodiment, the passive material discharging area is placed above the guide member. When passive material discharging occurs, the pushing member descends along the avoidance section to below the passive material discharging area to avoid interference with the passive material discharging. When the tail material cannot be discharged passively, the pushing member slides into the pushing section along the inclined avoidance section, and the pushing member rises to the end of the tail material, and the tail material is discharged by moving along the discharging direction through linear drive.

[0038] In this embodiment, the pushing section 55 is consistent with the material discharging direction, and the pushing member 52 slides along the pushing section 55 to move the material along the material discharging direction.

[0039] The pushing section is consistent with the discharging direction. When the pushing piece moves along the pushing section, the pushing piece moves along the discharging direction to discharge the tail material smoothly.

[0040] In this embodiment, the pushing section is placed below the material discharge area. When the tail material needs to be pushed, the pushing piece slides from the avoidance section to the pushing section, and the pushing piece rises to contact the end of the tail material, and the tail material discharge is completed through the action of the linear drive member.

[0041] As another embodiment, the material pushing section 55 is a bottom rail 57 for conveying materials.

[0042] In this embodiment, the pusher 52 is elastically rotatably connected to the linear drive 51 .

[0043] When the pusher slides along the guide to avoid and push materials, the height of the pusher is different. In order to achieve the avoidance and pushing of the pusher, the pusher is designed to be a rotatable structure so that the angle between the pusher and the linear drive can be adjusted. In order to further ensure the stability of the pusher, the space between the pusher and the linear drive is designed to be elastic and rotatable.

[0044] In this embodiment, the pusher and the linear drive are elastically connected to each other through a rotating shaft with a coil spring.

[0045] In this embodiment, an L-shaped connecting piece connected to the pushing piece is provided at the output end of the linear driving piece, so that the pushing piece is placed above the linear driving piece, thereby saving space.

[0046] In this embodiment, the pushing member 52 includes a pushing portion 521 which is perpendicular to the discharge direction and a connecting portion 522 for connecting the pushing portion 521 with the output end of the linear driving member 51. The pushing portion 521 moves along the guide member 53, and the connecting portion 522 is provided with a roller 523 which is slidably connected to the guide member 53.

[0047] The connecting part is used to connect the pushing part and the linear driving part, so that the pushing part is perpendicular to the discharging direction when moving along the pushing section, which is convenient for pushing out the tail material; a roller slidably connected to the guide part is provided on the connecting part, so that the pushing part reduces wear when moving along the guide part.

[0048] In this embodiment, the connecting portion is perpendicular to the pushing portion. When the pushing member moves along the avoidance section of the guide member, the angle between the connecting portion and the discharge direction can be changed to ensure that the height position of the pushing portion changes, thereby achieving avoidance and pushing.

[0049] In this embodiment, the roller is disposed on the connecting portion and close to the pushing portion.

[0050] In this embodiment, the guide member 53 is provided with a slide groove 56 for the pushing member 52 to pass through.

[0051] The pusher slides through the slide groove and the guide member. When the pusher moves along the slide groove, the height position of the pusher can be changed, thereby achieving avoidance and pushing.

[0052] In this embodiment, the guide member is provided with a chute connecting the avoidance section and the material pushing section, and the roller on the material pushing member spans the chute. As another embodiment, the material pushing member is slidably connected to the chute.

[0053] In this embodiment, the pusher 52 is placed above the linear drive 51 , and the pusher 52 is connected to the output end of the linear drive 51 via an L-shaped connector.

[0054] The pusher is above the linear drive, which can effectively save space.

[0055] In this embodiment, Figure 3 It is a state diagram of the pusher sliding from the avoidance section into the push section.

[0056] The working principle of the utility model is as follows: the material is pushed out of the end through the entry of the next material, and the passive discharge is performed; in the process of passive discharge, the linear drive is connected with the pusher, and the avoidance section is inclined along the discharge direction. When the pusher moves along the inclined avoidance section, the height of the pusher can be adjusted, so that when the material is passively discharged, the pusher can slide in the avoidance section to a height that is not within the range of the material to achieve the avoidance effect; when there is no next material entering, the tail material will be left in the discharge area, and it is inconvenient to take it manually and the tail material will be left in the discharge area. There are safety risks. When passive discharging cannot complete the tail material discharging, the utility model is connected to the pushing member through a linear drive. The linear drive drives the pushing member to move along the avoidance section of the guide member to the pushing section. At this time, the pushing member can move to the end of the tail material, and move along the discharging direction through the linear drive, driving the pushing member to push the tail material out from the end of the tail material to complete the pushing. The utility model has only one linear drive member, which is combined with a guide member with an avoidance section and a pushing section, which can meet the requirement of the pushing member to push the tail material out without interfering with passive discharging. At the same time, it has few parts and occupies little space.

[0057] Embodiment 2:

[0058] like Figure 1-5 A wrapping machine shown includes a material platform 1, a heat sealing mechanism 2, a transfer mechanism 3 and a discharging station 4. The transfer mechanism 3 is used to move the material on the material platform 1 to the heat sealing mechanism 2. The discharging station 4 is arranged on the side of the heat sealing mechanism 2 opposite to the material platform 1. It is characterized in that the heat sealing mechanism 2 is provided with a discharging mechanism described in Example 1.

[0059] The wrapped materials are transported to the material platform, and the materials are moved along the heat sealing mechanism through the transfer mechanism to complete the heat sealing of the materials. The heat-sealed materials are discharged along the discharging station under the thrust of the next material entering. When the last material enters the waiting discharging area, passive discharging cannot be achieved because no material enters. The utility model pushes the tailings to the discharging station through the provided discharging mechanism to complete the discharging of the tailings.

[0060] In this embodiment, a heat dissipation section 6 is provided at the output end of the heat sealing mechanism 2 , and the discharging mechanism 5 is placed below the heat dissipation section 6 .

[0061] After the heat sealing is completed, the material enters the heat dissipation section at the tail of the heat sealing mechanism. Before the next material comes, the current material stays on the heat dissipation section to achieve heat dissipation; when there is no next material coming, the last material will stay in the heat dissipation section to avoid burns and other safety issues caused by manual handling. The utility model sets a discharging mechanism below the heat dissipation section. Since the heat dissipation section is short, the problem of limited space below needs to be considered when designing the discharging mechanism. The tail material processing mechanism set in the utility model can achieve material pushing and avoidance through a driving and guiding member, with fewer parts and less space occupation.

[0062] In this embodiment, discharging pieces inclined downward are provided on both sides of the discharging station, and the material slides out between the discharging pieces.

[0063] In this embodiment, the material passes between the heat sealing mechanisms.

[0064] In this embodiment, a gap is provided between the heat dissipation sections for the material pushing member to pass through.
