Description

Technical Field

[0001] The present invention relates to the technical field of packaging material production equipment, and particularly relates to a forming bubble film separation device. Background Art

[0002] Currently, when packaging different items and cartons, bubble film is often used to package the items. When using the existing bubble film, the staff needs to first tear off the appropriate number of film pieces according to the size of the item, and then pack the item. Before tearing the film, the staff has to confirm the length of the torn film first. For some large items that require a large number of film pieces, it takes a certain amount of time and effort to confirm the number of film pieces. In some cases where bubble film is formed using degradable paper-plastic film consumables, due to the characteristics of the consumables, it is easy to tear the consumables during the process of tearing along the dotted line, and it is necessary to be very careful to tear along the dotted line, resulting in low packing efficiency of the workers.

[0003] At the same time, since it is manual film tearing, the consistency of the number of torn film pieces cannot be guaranteed. The number of film pieces is likely to be too many or too few. Too many film pieces will cause waste of the film, and too few film pieces may cause the item to be inadequately wrapped and damaged during transportation, bringing certain losses to the customer.

[0004] There are some separation devices for bubble film in the prior art, such as the equipment disclosed in Patent US7571589B2. However, this kind of equipment can only be used for bubble film with a width of a single bubble size. For bubble film with a larger width (such as a row having 4 or more bubbles arranged side by side), this equipment is not applicable. If the equipment needs to be modified, its overall width needs to be increased to adapt to larger-sized bubble film. In order to make the modified equipment applicable to more sizes of bubble film, only the overall width of the equipment can be increased as much as possible so that the width size of the bubble film is not greater than the overall width of the equipment. And such a setting will inevitably lead to an increase in the size of the overall equipment. The too-large equipment size will occupy a large amount of space, and at the same time, the too-large equipment size will also affect the stability of use. Summary of the Invention

[0005] In view of the deficiencies of the prior art, the present invention provides a forming bubble film separation device. It can be applicable to bubble films with different width sizes and can significantly reduce the size of the equipment.

[0006] According to one aspect of the present invention, there is provided a forming bubble film separation device, including

[0007] a frame having a feed inlet and a discharge outlet. A first transmission component and a second transmission component are arranged in the middle of the frame. The second transmission component is arranged downstream of the first transmission component, and the end of the first transmission component is connected to the head of the second transmission component;

[0008] The supporting bracket is arranged outside the feeding port on the frame. The supporting bracket includes a supporting part, and an adjusting structure for adjusting the width of the supporting part and the relative position between the supporting part and the feeding port is also arranged on the supporting bracket;

[0009] The first transmission component and the second transmission component have a first working condition and a second working condition. The first working condition is set such that the first transmission component and the second transmission component are set to drive the bubble film at the same speed in the first direction. The second working condition is set such that the first transmission component is set to drive the bubble film in the second direction, and the second transmission component is set to drive the bubble film in the first direction. Wherein, the first direction is the direction from the feeding port to the discharging port, and the second direction is the direction from the discharging port to the feeding port.

[0010] The formed bubble film separating device of the present invention drives and tears the bubble film through the first transmission component and the second transmission component on the frame, and a supporting bracket is also arranged on the frame, so that the width of the frame does not need to be greater than the width of the bubble film. At the same time, in the present invention, the bubble film is separated by the way of reverse tearing, so that it can be ensured that the bubble film can be completely separated when being torn, and there will be no situation that the separation is incomplete due to the too large width of the bubble film. Specifically, during operation, the bubble film located upstream is supported by the supporting bracket, so that the bubble film near the feeding port can be as parallel as possible to the bubble film inside the device to ensure the effect of separating the bubble film and avoid incomplete separation. After the bubble film is torn, since the bubble film near the discharging port has been separated and torn and does not need to be torn again, the too-wide part on the bubble film can droop freely without support.

[0011] In some embodiments, both the first transmission component and the second transmission component are set as a conveyor belt assembly including a first conveyor belt and a second conveyor belt. A part of the first conveyor belt and the second conveyor belt are in contact with each other, and their moving directions are set to be opposite to each other for clamping and driving the bubble film;

[0012] Both the first transmission component and the second transmission component are arranged on one side of the frame, and a receiving space is also arranged on the frame.

[0013] Thus, by such an arrangement, the conveyor belt assembly only contacts a part in the middle of the bubble film to drive the bubble film. At the same time, the two conveyor belts of the conveyor belt assembly are in contact with each other, so as not to contact the bubble part in the bubble film. The redundant bubble film can be placed in the receiving space and move together with the part of the bubble film in contact with the conveyor belt assembly, thereby reducing the structural complexity of the conveyor belt assembly and effectively reducing the conveyor belt width of the conveyor belt assembly.

[0014] In some embodiments, the supporting bracket includes a bracket body, the bracket body is connected to the frame, a first supporting member is disposed in the middle of the bracket body, and the adjusting structure includes a first stopper and a second stopper slidably disposed on the first supporting member. A position on the first supporting member between the first stopper and the second stopper forms a supporting portion.

[0015] Thus, by such an arrangement, the first stopper and the second stopper can be used to adjust the portion of the first supporting member that contacts the bubble film, so as to limit the width of the bubble film, and at the same time, the position of the bubble film can be limited, ensuring that the running path of the bubble film is correct and the position of the bubble film is correct, so as to ensure the working stability when separating the bubble film.

[0016] In some embodiments, the first supporting member is a roller rotatably disposed on the bracket body.

[0017] Thus, by such an arrangement, the roller can be used to reduce the friction between the bubble film and the first supporting member, avoiding affecting the integrity of the bubble film.

[0018] In some embodiments, a second supporting member parallel to the first supporting member is further disposed on the bracket body, and the first stopper and the second stopper are simultaneously slidably disposed on the first supporting member and the second supporting member.

[0019] Thus, by such an arrangement, the second supporting member can be used to further support the bubble film, so that the discharging direction of the bubble film production equipment can be opposite to the feeding direction of the equipment of the present invention. At the same time, a gap can be formed between the second supporting member and the first supporting member to prevent the bubble film from stacking and entering the feeding port of the equipment.

[0020] In some embodiments, a head seeking component is disposed between the first transmission component and the second transmission component. The head seeking component is a photoelectric sensor, and the head seeking component faces the bubble film to determine whether the end of the bubble film is conveyed out of the first transmission component.

[0021] Thus, by such an arrangement, the photoelectric sensor can be used to identify the end of the bubble film. Since in the second working condition, the end of the bubble film will be conveyed towards the feeding port, it is necessary to re-determine the position of the end of the bubble film, and then further determine the moment when separating the bubble film in the second working condition.

[0022] In some embodiments, an electrostatic removal brush is disposed at the discharging port.

[0023] Thus, by such an arrangement, the bubble film can be removed of static electricity, avoiding the problem that the separated bubble film is adsorbed on the equipment by static electricity and does not fall.

[0024] In some embodiments, a material stop assembly is provided at the discharge port. The material stop assembly is configured to apply a clamping pressure to the bubble film so that the bubble film is clamped and stopped at the discharge port.

[0025] Thus, by such an arrangement, the separated bubble film can be clamped by the material stop assembly, preventing the bubble film from flying out of the device at the discharge port and making it more convenient for the user to pick up the separated bubble film.

[0026] In some embodiments, the material stop assembly includes a clamping plate and a brush assembly. The clamping plate is disposed on a first side of the discharge port and is parallel to the discharge direction of the discharge port. The brush assembly is disposed on a side of the discharge port opposite to the first side. The distance between the end of the brush assembly facing the clamping plate and the clamping plate is not greater than the thickness of the bubble film.

[0027] Thus, by such an arrangement, the bubble film can be clamped by the brush and the clamping plate. The brush has good deformation performance and is not likely to affect the shape of the bubble film.

[0028] In some embodiments, one side of the supporting bracket is flush with the same side on the frame. The width of the supporting portion is set to be not less than the width of the frame and not greater than twice the width of the frame.

[0029] Thus, by such an arrangement, it can be ensured that the bubble film placed in the device can be clamped and driven by the first drive assembly and the second drive assembly in the device, ensuring the stability of the device operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0040] The present invention will be further described in detail below with reference to the accompanying drawings.

[0041] Figure 1 and Figure 2 schematically shows the overall structural composition of the formed bubble film separation device according to an embodiment of the present invention. Refer to Figure 1 and Figure 2As shown in the figure, the forming bubble film separating device of the present invention includes a frame 1. The frame 1 is provided with a feed inlet 11 and a discharge outlet 12. A first transmission assembly 21 and a second transmission assembly 22 are arranged in the middle of the frame 1. The second transmission assembly 22 is arranged downstream of the first transmission assembly 21. The end of the first transmission assembly 21 is connected to the head of the second transmission assembly 22. When the bubble film passes through the frame 1, it sequentially passes through the feed inlet 11, the first transmission assembly 21, the second transmission assembly 22 and the discharge outlet 12. The connection between the end of the first transmission assembly 21 and the head of the second transmission assembly 22 mentioned here does not mean that the end of the first transmission assembly 21 and the head of the second transmission assembly 22 are completely seamlessly spliced, but that they are arranged in sequence, and there may be a corresponding gap between them. Among them, the first transmission assembly 21 and the second transmission assembly 22 have a first working condition and a second working condition. The first working condition is the working condition of conveying the bubble film. The first transmission assembly 21 and the second transmission assembly 22 are both set to drive the bubble film at the same speed in the first direction. This first direction is the direction from the feed inlet 11 to the discharge outlet 12, that is, the forward transmission of the bubble film is realized. The second working condition is the working condition of separating the bubble film. The first transmission assembly 21 is set to drive the bubble film in the second direction, and the second transmission assembly 22 is set to drive the bubble film in the first direction. This second direction is the direction from the discharge outlet 12 to the feed inlet 11, that is, the reverse transmission of the bubble film is realized. When the first working condition is realized, the first transmission assembly 21 and the second transmission assembly 22 drive the bubble film forward synchronously and at the same speed. When the second working condition is realized, the first transmission assembly 21 drives in the reverse direction, and the second transmission assembly 22 drives in the forward direction, so that the bubble film is torn between the first transmission assembly 21 and the second transmission assembly 22 to realize the separation of the bubble film. Refer to Figure 1 As shown in the figure, in some embodiments, an outer housing 16 may be provided outside the frame 1 to protect the internal structure of the frame 1.

[0042] Refer to Figure 1 and Figure 2As shown, the frame 1 is further provided with a supporting bracket 3. Specifically, the supporting bracket 3 is arranged outside the feeding port 11 on the frame 1. The supporting bracket 3 is used to support the bubble film before it enters the frame 1. It includes a supporting portion 33, and an adjusting structure 4 for adjusting the width of the supporting portion 33 and the relative position between the supporting portion 33 and the feeding port 11 is also arranged on the supporting bracket 3. By providing the supporting bracket 3, when separating a bubble film with a larger width, when the bubble film passes through the frame 1, part of the bubble film will extend into the frame 1 and be driven by the first transmission component 21 and the second transmission component 22, while the other part of the bubble film will extend outside the frame 1 and be supported by the supporting bracket 3, reducing the influence of the change in the shape of the bubble film on the transmission and separation of the bubble film. By adjusting the width of the position on the supporting bracket 3 for supporting the bubble film, the width of the supporting portion 33 can be adaptively changed according to the different width sizes of the bubble film to be separated. Adjusting the width of the supporting portion 33 to correspond to the width of the bubble film can limit the bubble film, thus avoiding the displacement of the bubble film when passing through the whole device and affecting the separation effect. At the same time, adjusting the relative position between the supporting portion 33 and the feeding port 11 can adjust the size of the bubble film extending into the frame 1 and the size of the bubble film exposed outside the frame 1.

[0043] Regarding the structures of the first transmission component 21 and the second transmission component 22, they can be implemented as conveyor belt components. The conveyor belt can drive the movement of the bubble film to achieve the transmission of the bubble film. The conveyor belt component includes a first conveyor belt 23 and a second conveyor belt 24. The first conveyor belt 23 and the second conveyor belt 24 are arranged opposite to each other and have a part in contact with each other, and their moving directions are set to be opposite to each other for clamping and driving the bubble film. Both the first conveyor belt 23 and the second conveyor belt 24 are driven by a combination of a driving wheel 25 and a driven wheel 26. Since the first conveyor belt 23 and the second conveyor belt 24 rotate synchronously, the conveyor belt component can drive the driving wheels 25 of the first conveyor belt 23 and the second conveyor belt 24 to rotate synchronously and at the same speed through the transmission between a driving motor, gears, pulleys and belts. Specifically, the relevant structure of the conveyor belt driving mechanism in the prior art can be referred to, and no further elaboration will be made on this part here.

[0044] In some possible implementation manners, both the first transmission component 21 and the second transmission component 22 are arranged on one side of the frame 1, and a receiving space 13 is also arranged on the frame 1. Specifically, refer to Figure 4As shown, in this embodiment, the conveyor belt widths of the first transmission assembly 21 and the second transmission assembly 22 are set to be relatively small, so that the conveyor belt width is not greater than the interval size between adjacent bubbles in the width direction of the bubble film, so as to enable the portion where the first conveyor belt 23 and the second conveyor belt 24 are in contact with each other to clamp the interval position between adjacent bubbles in the width direction of the bubble film to drive the bubble film to move. When the bubble film is clamped and moved, the portion on the side of the bubble film facing the inside of the frame 1 can be placed in the accommodation space 13 to avoid excessive sagging due to gravity, which affects the transmission and separation of the bubble film. And the portion on the side of the bubble film facing the outside of the frame 1 can be supported by the support bracket 3, so that at least the section of the bubble film near the feed port 11 can be supported, avoiding affecting the transmission and separation of the bubble film. Refer to Figure 4 As shown, the accommodation space 13 is arranged inside the frame 1. An upper plate 14 and a lower plate 15 are arranged inside the frame 1. The upper plate 14 is arranged above the conveyor belt assembly, and the lower plate 15 is arranged below the conveyor belt assembly. The space between the upper plate 14 and the lower plate 15 forms the accommodation space 13. Refer to Figure 2 As shown, the first transmission assembly 21 and the second transmission assembly 22 are arranged on one side of the frame 1, and the drive structures of the first transmission assembly 21 and the second transmission assembly 22 are arranged on the opposite side of the frame 1.

[0045] For the support bracket 3, it may include a bracket body 34. The bracket body 34 is connected to the frame 1 and is arranged outside the feed port 11 on the frame 1. A first support member 31 is arranged on the bracket body 34. The first support member 31 is used to form a support portion 33 to support the bubble film. The adjustment structure 4 includes a first stop block 41 and a second stop block 42 slidably arranged on the first support member 31. The first stop block 41 and the second stop block 42 form limits on both sides of the portion of the first support member 31 used to support the bubble film through the sliding arrangement on the first support member 31, so that the position on the first support member 31 between the first stop block 41 and the second stop block 42 forms the support portion 33. Further, in order to reduce the influence of the friction force of the first support member 31 on the bubble film when the bubble film passes through the first support member 31, so that the bubble film is worn, etc., the first support member 31 can be set as a roller. Refer to Figure 1 and Figure 2 As shown, in the figure Figure 1 and Figure 2In the illustrated embodiment, the support body 34 is formed in a horizontally placed "C shape", one side of which is flush with the same side on the frame 1. The first supporting member 31 is a roller, and both ends are rotatably connected to both ends of the support body 34. The first stopper 41 and the second stopper 42 are slidably arranged on the first supporting member 31 to form a supporting portion 33. By dynamically adjusting the positions of the first stopper 41 and the second stopper 42, the width of the supporting portion 33 and the relative position between the supporting portion 33 and the feed inlet 11 can be adjusted. In addition, scales can be provided on the first supporting member 31 to facilitate the user as an adjustment standard during adjustment. For the width of the supporting portion 33, it is specifically set that the width of the supporting portion 33 is not less than the width of the frame 1 and not greater than twice the width of the frame 1. Through such a design, it can be ensured that no matter how the relative position between the supporting portion 33 and the feed inlet 11 is adjusted, the bubble film placed in the device can be clamped and driven by the first transmission assembly 21 and the second transmission assembly 22 in the device, ensuring the stability of the device operation.

[0046] In addition, in some possible embodiments, a second supporting member 32 parallel to the first supporting member 31 can also be provided on the support body 34, and the first stopper 41 and the second stopper 42 are arranged to be slidably arranged on both the first supporting member 31 and the second supporting member 32 at the same time. Specifically, referring to Figure 2 as shown, in Figure 2 the illustrated embodiment, the second supporting member 32 is arranged above the first supporting member 31 and is arranged as a connecting rod, and both ends of the connecting rod are fixedly arranged on the support body 34. The first stopper 41 and the second stopper 42 are simultaneously slidably arranged on both the first supporting member 31 and the second supporting member 32, and clamping structures are arranged at the positions where the first stopper 41 and the second stopper 42 are connected to the second supporting member 32 to be used for fixing the positions of the first stopper 41 and the second stopper 42. At this time, the scale can be arranged on the second supporting member 32. The specific clamping structure is arranged to include a first clamping block and a second clamping block. The second supporting member 32 is clamped between the first clamping block and the second clamping block, and the first clamping block and the second clamping block are connected by bolts. Then, by tightening the bolts, the clamping of the second supporting member 32 can be realized to fix the positions of the first stopper 41 and the second stopper 42. By adding the second supporting member 32, the bubble film can be further supported around the second supporting member 32, so that no matter from any different direction and angle when the bubble film is discharged, the bubble film can be supported by the supporting frame 3 to be fed from the feed inlet 11 of the bubble film separating device. At the same time, a rectangular inlet structure 35 is formed between the first supporting member 31 and the second supporting member 32, so that the bubble film needs to pass through the inlet structure 35 before entering the device from the feed inlet 11, thus avoiding the situation that the bubble film is folded, affecting the entry of the bubble film into the device and the separation of the bubble film.

[0047] In order to better determine the length of the separated bubble film, a head-finding component 5 can also be provided on the rack 1 to judge the position of the current bubble film in the rack 1. Specifically, the head-finding component 5 can be set as a photoelectric sensor. The head-finding component 5 can be arranged between the first transmission component 21 and the second transmission component 22 and face the bubble film, so as to be able to judge the length dimension of the separated bubble film when the control device executes the second working condition. Exemplarily, referring to Figure 3 as shown in Figure 3 In the shown embodiment, the head-finding component 5 is set as a photoelectric sensor and is arranged between the first transmission component 21 and the second transmission component 22. Since the device is in uniform transmission when executing the first working condition, when the transmission starts, the head-finding component 5 senses the end of the bubble film, and then according to the transmission time and the transmission speed, the length passed by the bubble film can be judged, so as to be able to judge the length dimension of the separated bubble film when executing the second working condition at the current moment. In addition, the length dimension of the separated bubble film when executing the second working condition at the current moment can also be judged by monitoring the number of turns of the motor and the length of the bubble film passing by for each turn of the motor.

[0048] In addition, an antistatic brush 6 can also be provided at the discharge port 12 of the rack 1. The antistatic brush 6 can remove static electricity from the discharged bubble film to prevent the separated bubble film from being adsorbed on the device by static electricity and unable to fall by itself. Specifically, referring to Figure 1 as shown in Figure 1 In the shown embodiment, the antistatic brush 6 is arranged above the discharge port 12 and the bristles droop, so that the bubble film coming out of the discharge port 12 can contact the static electricity brush to remove static electricity from the discharged bubble film. The length of the static electricity brush is the same as the width of the discharge port 12 to realize removing static electricity from the bubble film coming out of the discharge port 12 at the same time.

[0049] In some possible embodiments, a stop component can also be provided at the discharge port 12 of the whole device. The stop component is used to apply a clamping pressure to the bubble film so that the bubble film from the discharge port 12 is clamped and stopped at the discharge port 12, which is convenient for the user to directly take it. Specifically, the stop component can include a clamping plate 72 and a brush component 71. Among them, the clamping plate 72 is arranged on the first side of the discharge port 12 and is arranged parallel to the discharge direction of the discharge port 12. The brush component 71 is arranged on the side of the discharge port 12 opposite to the first side, so that the clamping plate 72 and the brush component 71 are arranged opposite to each other to clamp the bubble film discharged from the discharge port 12. Referring to Figure 1 as shown in Figure 1In the shown embodiment, the clamping plate 72 is arranged at the lower part of the discharge port 12, and its length is the same as the width of the discharge port 12. The brush assembly 71 is arranged at the upper part of the discharge port 12, and the brush assembly 71 is only arranged at the position corresponding to the position of the second transmission assembly 22 at the discharge port 12, so as to reduce the installation amount of the brush assembly 71. The interval between the end of the brush assembly 71 facing the clamping plate 72 and the clamping plate 72 is set to be not greater than the thickness of the bubble film, so that the better deformation performance of the bristles of the brush assembly 71 itself can be utilized, and the bubble film is clamped by the deformation of the bristles and the clamping plate 72. At the same time, because the bristles are relatively soft, it is not easy to affect the shape of the bubble film. The clamping plate 72 can be set as a collision-proof plate made of polyurethane, so as to relieve the injury suffered by the user when colliding with the clamping plate 72 during use and improve the safety of the equipment. It can be understood that the setting of the material stop assembly and the setting of the static electricity brush in this embodiment can be set synchronously together, and the settings of the two will not affect each other, and the setting of the clamping plate 72 can also make the static electricity brush better contact with the bubble film to remove static electricity from the bubble film.

[0050] The formed bubble film separating device of the present invention drives and tears the bubble film through the first transmission assembly 21 and the second transmission assembly 22 on the frame 1, and a supporting bracket 3 is also arranged on the frame 1, so that the width of the frame 1 does not need to be greater than the width of the bubble film. At the same time, in the present invention, the bubble film is separated by the way of reverse tearing, so that it can be ensured that the bubble film can be completely separated when torn, and there will be no situation that the separation is incomplete due to the too large width of the bubble film. Specifically, during the operation, the bubble film located upstream is supported by the supporting bracket 3, so that the bubble film near the feed port 11 can be kept parallel to the bubble film located inside the equipment as much as possible to ensure the effect of separating the bubble film and avoid incomplete separation. When the bubble film is torn, since the bubble film near the discharge port 12 has been separated and torn and does not need to be torn again, the too wide part of the bubble film can droop freely without support.

[0051] When the formed bubble film separation device of the present invention is in use, first, the width of the supporting part 33 on the supporting bracket 3 is adjusted according to the width of the bubble film to be separated. Then, the bubble film winds around the first supporting member 31 and the second supporting member 32 on the supporting bracket 3, and passes through the inlet structure 35 formed between the first supporting member 31 and the second supporting member 32, and is placed into the feed port 11 through the supporting part 33. When the device is started, the first working condition is first executed so that the first transmission component 21 and the second transmission component 22 drive the bubble film towards the discharge port 12 at the same speed. During the transmission, the bubble film passes between the first transmission component 21 and the second transmission component 22 and is detected by the head seeking component 5 to start calculating the length of the transmitted bubble film. When the preset threshold standard is reached, the head seeking component 5 will send a signal to control the operation of the device, causing the current working condition to switch from the first working condition to the second working condition. After the second working condition is executed, the first transmission component 21 and the second transmission component 22 will operate in opposite directions to tear and separate the bubble film. The bubble film on the side of the second transmission component 22 after separation will continue to be transmitted to the discharge port 12, while the bubble film on the side of the first transmission component 21 will be transmitted a certain distance towards the feed port 11. After the separated bubble film is discharged from the discharge port 12, it will be de-electrified by the static elimination brush 6 and stop at the discharge port 12 under the clamping of the brush assembly 71 and the clamping plate 72, and the user can directly take it. When the separation of the bubble film needs to be carried out again, the first working condition will be executed again, so that the bubble film is transmitted from the first transmission component 21 to the second transmission component 22 and is transmitted towards the discharge port 12. At this time, it will be detected again after passing through the head seeking component 5 to continue calculating the length of the transmitted bubble film.

[0052] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
