Description

Technical Field

[0001] The present invention relates to the technical field of static eliminators, and particularly to a static eliminator for batch removing static electricity from the surface of a film. Background Art

[0002] The surface of an existing ID card has a polyethylene terephthalate (PET) film. During the ID card manufacturing process, the printed film has strong static electricity, which causes the batch-printed PET films to adsorb to each other, resulting in static adhesion of the films.

[0003] During the reservation process using a machine, due to the static adhesion effect, it is easy to take out multiple films at once when taking the film, resulting in abnormal shutdown of the machine and affecting the overall efficiency. Summary of the Invention

[0004] In view of the above-mentioned disadvantages of the related art, the present application provides a static eliminator for batch removing static electricity from the surface of a film to solve the above technical problems.

[0005] The present application provides a static eliminator for batch removing static electricity from the surface of a film. The static eliminator includes a silo and a separator for contacting and separating the films. The silo has a receiving space for stacking the films. The separator extends into the receiving space. After the separator contacts and separates the films, the separator tilts relative to the silo, and the separator can abut against and drive the films so that multiple films are stacked in sequence obliquely.

[0006] The technical solution adopted by the present invention can achieve the following beneficial effects: The receiving space in the silo can stack the films, and the separator extends into the receiving space. The separator can contact and separate the films, and two adjacent films can be separated from each other or partially separated. At this time, the separator tilts relative to the silo, and the separator can abut against and drive the films so that multiple films are stacked in sequence obliquely. After the multiple films are separated, the multiple films are stacked in sequence obliquely. When taking the film, one hand can directly touch the edge of the upper film without contacting or wrongly taking away the lower film, reducing the risk of taking out multiple films at the same time and improving the card-making efficiency. In addition, compared with the case of vertical stacking, the contact area between two adjacent obliquely stacked films is reduced, which makes it easier to overcome the adhesion force when taking away the upper film and easier to take it off separately from multiple films, improving the taking efficiency.

Detailed implementation manners

[0010] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other implementation manners obtained by those of ordinary skill in the art without creative efforts fall within the scope protected by the present invention.

[0011] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of this application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / ", generally represents an "or" relationship between the associated objects before and after.

[0012] An electrostatic eliminating device 1 for batch removing static electricity on the surface of a film is provided in an embodiment of this application, hereinafter simply referred to as the electrostatic eliminating device 1. Please refer to Figure 1 , the electrostatic eliminating device 1 may include a silo 110 and a separating member 120, and the silo 110 and the separating member 120 are connected.

[0013] Please refer to Figure 1 , the silo 110 can be a metal silo, such as a stainless steel silo or a copper silo, etc. The metal silo 110 can quickly conduct static electricity to prevent the static electricity of the electrostatic eliminating device 1 from being conducted to the film 2. The silo 110 has a receiving space 111 for stacking the film 2. The size and shape of the receiving space 111 can be adapted to the film 2, which is beneficial to the stacking of the film 2 and can prevent the film 2 from wrinkling. Among them, the film 2 can be a polyethylene terephthalate film, etc., and the type, specification, or quantity of the film 2 is not limited.

[0014] Please refer to Figure 1 and Figure 2 , the separating member 120 is used to contact and separate the film 2, and the separating member 120 can be movably connected to the silo 110. And the separating member 120 extends into the receiving space 111, the separating member 120 can contact the film 2, and when the separating member 120 moves relative to the silo 110, the separating member 120 can drive a part of the film 2 to move relatively, so as to separate two adjacent films 2 from each other.

[0015] Please refer to Figure 2 and Figure 3, after the separating member 120 contacts and separates the film 2, the separating member 120 tilts relative to the magazine 110, and the separating member 120 can abut against and drive the film 2 so that a plurality of films 2 are stacked obliquely in sequence. Among them, as Figure 4 shown, the oblique stacking means that along the stacking direction of the plurality of films 2, the central axes of the plurality of films 2 are distributed in sequence along a predetermined direction. When taking out the obliquely stacked films 2, one hand can directly touch the edge of the upper film 2 without contacting or wrongly taking away the lower film 2, reducing the risk of taking out multiple films 2 simultaneously and improving the card-making efficiency. In addition, compared with the case of vertical stacking, the contact area between two adjacent obliquely stacked films 2 is reduced, which makes it easier to overcome the adhesion force when taking away the upper film 2 and easier to take it off separately from the plurality of films 2, improving the taking efficiency. Among them, the upper film 2 or the lower film 2 is used to distinguish two adjacent films 2, not completely two films 2 distributed in a certain specific direction.

[0016] In the embodiment of the present application, please refer to Figure 3 , before the oblique stacking, the films 2 located in the accommodating space 111 are stacked in sequence along the first direction (such as Figure 3 shown by x in Figure 3 ). A plurality of films 2 are in contact with each other and present a stacked state. The driven separating member 120 can tilt towards the second direction (such as Figure 3 shown by y in

[0017] ), and the separating member 120 abuts against and drives the film 2 so that a plurality of films 2 are stacked obliquely in sequence, and the first direction and the second direction intersect or are perpendicular. Due to the abutting and driving action of the separating member 120, the plurality of sequentially stacked films 2 are subjected to force and tilt. According to the different distances from the tilting axis of the separating member 120, the moving distances of the plurality of sequentially stacked films 2 after being driven are also different, which can also make the central axes of the plurality of films 2 distributed in sequence along a predetermined direction along the stacking direction of the plurality of films 2. Therefore, along the direction away from the tilting axis of the separating member 120, the moving distances of the plurality of sequentially stacked films 2 gradually increase so that the plurality of films 2 are stacked obliquely, which can improve the taking convenience of the films 2.

[0017] Preferably, in the second direction, the height of the magazine 110 gradually increases, which makes the film 2 located in the magazine 110 inclined relative to the horizontal plane. When the separating member 120 drives the upper film 2 to move, the component force of the gravity of the lower film 2 can resist the adhesion force between the films 2, preventing the lower film 2 from being taken away by the upper film 2 and improving the use safety.

[0018] Please refer to Figure 2The silo 110 has two opposite first side panels 113, two opposite second side panels 114 and a bottom panel 112, and the two opposite first side panels 113, two opposite second side panels 114 and the bottom panel 112 enclose a receiving space 111 for receiving the film 2. Exemplarily, the two opposite first side panels 113 and the two opposite second side panels 114 are distributed along the edge of the bottom panel 112, thereby enclosing a semi-open receiving space 111, that is, the receiving space 111 is exposed through the top of the silo 110, so that the operator can put the film 2 from the top of the silo 110.

[0019] See also Figure 3 , the two ends of the first side plate 113 are respectively rotatably matched with the two second side plates 114, for example, the first side plate 113 is provided with a rotating shaft, and the opposite ends of the rotating shaft can be respectively inserted into the holes of the two second side plates 114, so that the first side plate 113 can rotate around the rotating shaft. Of course, both of the two first side plates 113 can be rotatably matched with the second side plates 114, which is not limited here. The two first side plates 113 can be switched between the first state and the second state. When the first side plate 113 is in the first state, the two first side plates 113 are perpendicular to the bottom plate 112. Further, the two second side plates 114 can be perpendicular to the bottom plate 112, so that the cross section of the accommodating space 111 is rectangular, and the stacked films 2 can be neatly placed in the accommodating space 111. When the first side plate 113 is in the second state, the two first side plates 113 are tilted relative to the bottom plate 112. With the tilted setting of the two first side plates 113, the two sides of the film 2 placed in the accommodating space 111 will be subjected to the thrust generated by the rotation of the first side plate 113 and the second side plate 114. Due to the combined effect of the thrusts on both sides, the multiple films 2 will be tilted, and the multiple films 2 will gradually form a tilted stacking state under the action of the thrusts. Compared with the unilateral driving, this method of driving the film 2 from both sides at the same time can make the film 2 more evenly stressed, effectively avoiding the problems of deviation, wrinkles, etc. of the film 2 during the tilted stacking process, thereby realizing the orderly tilted stacking of the film 2.

[0020] In the embodiments of this application, please refer to Figure 5 and Figure 6 The static electricity removal device 1 further includes an ion blower 130. Further, the ion blower 130 can be a static electricity removal ion wind rod, etc., and is not limited. The ion blower 130 is used to discharge ion wind. Further, the ion blower 130 can generate a large number of positive and negative ions, which are driven by the airflow and discharged from the ion blower 130.

[0021] See also Figure 5 and Figure 6, the separating member 120 is disposed within the accommodating space 111. The separating member 120 is capable of lifting and lowering relative to the bottom plate 112 and scraping the edge of the film 2 located within the accommodating space 111. Exemplarily, a plurality of films 2 located within the accommodating space 111 are stacked to form a stacked body, and the side surface of the stacked body is uneven, i.e., there are minute protrusions or depressions. The surface of the separating member 120 may be provided with the hook surface of a Velcro, and the hook surface contacts the side surface of the stacked body. This enables fine hooks on the hook surface to be embedded in the seams between adjacent two films 2. When the separating member 120 and the magazine 110 move relative to each other, the fine hooks can drive the upper film 2 to separate, and adjacent two films 2 can be separated from each other or partially separated.

[0022] In some other cases, the separating member 120 may be a plate member structure with a rough surface, such as sandblasting treatment or etching process in machining, or by spraying a rough coating, etc. The separating member 120 is capable of rubbing the side surfaces of a plurality of films 2. The microscopic protrusions on the rough surface of the separating member 120 will be embedded in the minute gaps between the films 2. During the separating operation, an external force is applied to the separating member 120, and this strong frictional force enables the separating member 120 to effectively drive the film 2 in contact therewith to generate relative displacement.

[0023] At this time, driven by the separating member 120, adjacent two films 2 can be separated from each other to form a larger gap. The ion blower 130 is in communication with the accommodating space 111, and the ion blower 130 can blow air into the accommodating space 111 in a direction parallel to the bottom plate 112. The ionized air blown out by the ion blower 130 can enter the gap between adjacent two films 2. The ionized air can enter the gap. Due to the fluidity and diffusibility of the air flow, the ionized air discharged by the ion blower 130 can be quickly transmitted into the gap. Ions with an electrostatic polarity opposite to that of the film 2 surface in the ionized air will be attracted to the film 2 surface, and the charges of the ionized air and the static charges on the film 2 surface undergo a neutralization reaction, thereby eliminating the static electricity on the film 2 surface, so that adjacent two films 2 can be completely separated, and preventing the films 2 from being electrostatically adsorbed again. In addition, the ion blower 130 can also continue to blow air during the tilting process of the first side plate 113 to continuously eliminate the interference of static electricity.

[0024] Further, please refer to Figure 1 and Figure 3, the first side plate 113 and the second side plate 114 are provided with guide holes 115. The guide holes 115 can be strip-shaped holes, circular holes, etc., without limitation. The guide holes 115 are located in the blowing path of the ion blower 130. A plurality of thin films 2 located in the accommodating space 111 are stacked to form a stacked body. The guide holes 115 can guide the ion wind blown by the ion blower 130 so that the ion wind blows to the side surface of the stacked body. Among them, when the ion wind enters the guide holes 115, the air flow is first restricted by the inner wall of the guide holes 115. The initial turbulent flow state (turbulent flow) is gradually adjusted due to the frictional action of the channel wall surface and geometric guidance, and is gradually transformed into a laminar flow state of stratified flow. This laminar flow state of the air flow has a stable velocity distribution and flow direction, and can be more accurately guided to the side surface of the stacked body of the thin films 2 in the accommodating space 111. The stability of the laminar air flow also helps the positive and negative ions in the ion wind to more orderly neutralize the static charges on the surface of the thin film 2, improving the static elimination efficiency.

[0025] In addition, the guide holes 115 can guide the lifting movement of the separating member 120 relative to the bottom plate 112, and the separating member 120 is slidably matched with the guide holes 115. For example, the separating member 120 is provided with a connecting member, and the connecting member extends into the guide holes 115 and is slidably arranged along the guide holes 115. Among them, the extending direction of the guide holes 115 can be perpendicular to the bottom plate 112. This can realize the lifting movement of the separating member 120 relative to the bottom plate 112 and scrape the edges of the thin films 2 located in the accommodating space 111, improving the sliding effect of the separating member 120.

[0026] In the embodiment of the present application, please refer to Figure 6 , the static elimination device 1 may further include a flexible flow guide cover 140. The flexible flow guide cover 140 can be made of high molecular materials such as silicone rubber and polytetrafluoroethylene, and is made of materials with good flexibility and insulation. The flexible flow guide cover 140 can deform to adapt to different working conditions. The flexible flow guide cover 140 is connected between the ion blower 130 and the first side plate 113, and the flexible flow guide cover 140 can guide the ion wind to the guide holes 115. After the first side plate 113 is tilted and a plurality of thin films 2 are stacked obliquely, the flexible flow guide cover 140 can deform accordingly with the first side plate 113, always maintaining the effective guidance of the ion wind, so as to ensure that the ion wind can blow along the direction parallel to the bottom plate 112, ensuring that the ion wind stably and continuously plays the role of eliminating static electricity.

[0027] Of course, the number of ion blowers 130 can be multiple, such as 2, 3 or more, without limitation. Multiple ion blowers 130 can be distributed in different orientations of the silo 110. For example, at least one ion blower 130 is disposed on the side of the second side plate 114 away from the accommodating space 111 to discharge ionized air in different directions, so as to improve the anti-static effect. In addition, the number of flexible guide covers 140 can correspond to that of the ion blowers 130, that is, the flexible guide covers 140 and the ion blowers 130 are in one-to-one correspondence, that is, at least one flexible guide cover 140 is correspondingly disposed for one ion blower 130 to improve the anti-static effect of the ionized air.

[0028] In the embodiment of the present application, please refer to Figure 3 , the separating member 120 may include a first separating member 121 and a second separating member 122. For example, the first separating member 121 and the second separating member 122 may be plate-like structures of the same specification or shape, without limitation. Of course, in some cases, the first separating member 121 and the second separating member 122 may be two different structures to adapt to different functions and structures. The first separating member 121 is slidably engaged with the first side plate 113, and the second separating member 122 is slidably engaged with the second side plate 114. The sliding engagement methods include but are not limited to a slider and a chute or a slide rail and a sliding member, etc.

[0029] Please continue to refer to Figure 3 , the first separating member 121 is connected to the second separating member 122. For example, the first separating member 121 and the second separating member 122 are drivingly connected, and the specific connection methods include but are not limited to a slider and a chute or a slide rail and a sliding member, etc. And the second separating member 122 can push the first separating member 121 to slide relative to the first side plate 113. Specifically, the second separating member 122 is driven and movably disposed relative to the bottom plate 112 and the second side plate 114. The second separating member 122 can scrape the side surface of the stack formed by stacking a plurality of films 2. At the same time, the second separating member 122 also drives the first separating member 121 to slide relative to the first side plate 113, so that the first side plate 113 can scrape the other side surface of the stack. The second separating member 122 and the first separating member 121 act on the stack at the same time, which is beneficial to separating the plurality of films 2 and improving the anti-static effect.

[0030] Driven by the second separating sub-component 122, the first separating sub-component 121 drives the first side plate 113 to switch between the first state and the second state. That is, when the first separating sub-component 121 is driven by the second separating sub-component 122, the two first side plates 113 are tilted. With the tilting of the two first side plates 113, both sides of the film 2 placed in the accommodating space 111 will be subjected to the thrust generated by the rotation of the first side plate 113. Due to the combined action of the thrust on both sides, multiple films 2 will tilt, and multiple films 2 will gradually form an inclined stacked state under the action of this thrust. This setting can enable the first separating sub-component 121 and the second separating sub-component 122 to cooperate with each other, reducing the number of driving mechanisms.

[0031] In addition, the number of the first separating sub-component 121 and the second separating sub-component 122 can be multiple, or the number of the parts for scraping the film 2 in the first separating sub-component 121 and the second separating sub-component 122 is multiple, and multiple parts scrape the film 2 simultaneously to improve the scraping effect and avoid stress concentration and other situations in a single part.

[0032] It can be understood that, referring to Figure 3 , the static eliminator 1 may further include a driving member 160, and the driving member 160 can be a driving motor or a cylinder, etc., without limitation. The driving member 160 is used to drive the second separating sub-component 122 to move relative to the silo 110. Exemplarily, taking the driving motor as an example for introduction, the driving member 160 and the second separating sub-component 122 can be driven by a lead screw. The driving motor can drive the lead screw, and the lead screw drives the second separating sub-component 122 to move, and then the second separating sub-component 122 drives the first separating sub-component 121 to be movably arranged. In addition, in some cases, the second separating sub-component 122 can also move under the action of an external driving force (such as manual pushing, etc.).

[0033] In some other cases, the static eliminator 1 can include two driving members. One of the two driving members drives the first separating sub-component 121 and the second separating sub-component 122 to move up and down simultaneously, and the other can independently drive the first separating sub-component 121 to be rotatably arranged. This can also achieve two different moving states, which will not be elaborated here.

[0034] In the embodiments of the present application, referring to Figure 6, the separating member 120 may further include a support member 150. The support member 150 is provided with a first sliding groove 151. The first sliding groove 151 may include a first section 1511 and a second section 1512 that communicate with each other. The first section 1511 extends in a direction perpendicular to the bottom plate 112. The extending directions of the first section 1511 and the second section 1512 intersect. Exemplarily, both the first section 1511 and the second section 1512 are strip-shaped holes. The extending directions of the first section 1511 and the second section 1512 intersect, and there may be an included angle between them, such as 30°, 60° or 80°, etc., without limitation. The extending direction of the first section 1511 is the first direction, and the extending direction of the second section 1512 is along the second direction or its opposite direction. The second separating sub-member 122 is provided with a second sliding groove 1221. One end of the second sliding groove 1221 is correspondingly arranged with the first section 1511, and the other end extends toward the side of the first section 1511 close to the second section 1512. The first separating sub-member 121 has a sliding portion 1211, and the sliding portion 1211 passes through the first sliding groove 151 and the second sliding groove 1221 at the same time. Relative to the first section 1511, the extending direction of the second sliding groove 1221 is substantially the same as that of the second section 1512.

[0035] Please refer to Figure 6 and Figure 7 , the second separating sub-member 122 moves in a direction perpendicular to the bottom plate 112, and the movement path of the second separating sub-member 122 includes a first path and a second path. While the second separating sub-member 122 moves within the first path, it drives the sliding portion 1211 to slide along the first section 1511, so that the first separating sub-member 121 slides relative to the first side plate 113. In other words, the sliding portion 1211 can slide along the first section 1511 and be located at the end of the second sliding groove 1221 at the same time, so as to facilitate the sliding portion 1211 to be driven by the second separating sub-member 122 and slide along the first section 1511.

[0036] Please refer to Figure 7 and Figure 8, while the second separating sub-component 122 moves within the second path, it drives the sliding part 1211 to slide along the second section 1512, and the sliding part 1211 slides along the second chute 1221, so that the first separating sub-component 121 drives the first side plate 113 to switch between the first state and the second state. In other words, when the sliding part 1211 is at the junction of the first section 1511 and the second section 1512, the second separating sub-component 122 continues to move, and the sliding part 1211 is driven and will move along the second section 1512. At this time, because the sliding path of the second separating sub-component 122 is in the direction perpendicular to the bottom plate 112, the groove wall of the second separating sub-component 122 will limit the movement range of the sliding part 1211. Therefore, the setting of the second chute 1221 can provide a sliding space for the sliding part 1211, so that the sliding part 1211 can move along the side of the first section 1511 close to the second section 1512, so that the first separating sub-component 121 can be driven and rotated along its own rotation axis, ensuring that the second separating sub-component 122 can drive the first separating sub-component 121 to rotate, improving the use safety.

[0037] Among them, in one case, the length of the second section 1512 is less than or equal to the length of the second chute 1221. The range of the second chute 1221 is larger than the range of the second section 1512. When the sliding part 1211 moves along the second section 1512, the second chute 1221 will not interfere with the sliding part 1211. This ensures that the sliding part 1211 slides freely along the length direction of the chute, avoiding mechanical obstacles caused by the width of the second chute 1221.

[0038] In another case, along the direction perpendicular to the bottom plate 112, the height of the second section 1512 is less than or equal to the height of the second chute 1221. This can also ensure that the range of the second chute 1221 is larger than the range of the second section 1512, avoiding mechanical obstacles caused by the width of the second chute 1221.

[0039] In still another case, the length of the second section 1512 is less than or equal to the length of the second chute 1221, and at the same time, along the direction perpendicular to the bottom plate 112, the height of the second section 1512 is less than or equal to the height of the second chute 1221, improving the sliding effect of the sliding part 1211, which will not be elaborated here.

[0040] Preferably, the shape of the second section 1512 can be arc-shaped, and the center of the arc is located on the side of the support 150 close to the bin 110. The center of the arc can be on the rotation axis corresponding to the rotation of the first side plate 113 relative to the second side plate 114. This arc shape adapts to the rotation direction of the first side plate 113 or the second side plate 114, so that when the first separating sub-component 121 and the second separating sub-component 122 move along the second section 1512, they can rotate around the rotation axis of the first side plate 113 or the second side plate 114, improving the rotation effect.

[0041] It is understandable that the number of the first separated sub-components 121 can be multiple. The multiple first separated sub-components 121 are connected to two opposite first side plates 113 to improve the driving effect and stability. Of course, the first sliding groove 151 and the second sliding groove can be correspondingly set to be multiple, so as to facilitate the sliding or rotating setting of the multiple first separated sub-components 121, which will not be elaborated here.

[0042] In the embodiment of the present application, please refer to Figure 9 , the bottom plate 112 can be provided with a notch 1121. The shape of the notch 1121 can be rectangular, semi-circular, etc., without limitation. The notch 1121 faces at least one of the two first side plates 113. When multiple films 2 need to be placed into the accommodating space 111 on the bottom plate 112, the operator can directly send the film 2 into the accommodating space 111 through the open area formed by the notch 1121. The notch 1121 provides an avoidance space, avoiding the scraping or collision of the fingers with the edge of the bottom plate 112, which may cause the film 2 to tilt and wrinkle, etc. That is, it simplifies the placing action and reduces the possibility of the film 2 being stacked and misaligned due to inconvenient operation. When taking out the film 2, the operator can use the space provided by the notch 1121 to conveniently insert the finger or tool into the accommodating space 111 to grab the film 2. Compared with the closed bottom plate 112 without the notch 1121, this setting reduces the difficulty of taking out the film 2.

[0043] In addition, please continue to refer to Figure 9 , at least one of the first side plates 113 is also provided with an opening 1131. The opening 1131 is correspondingly set with the notch 1121 and is communicated with each other. The opening 1131 can reduce the interference of the first side plate 113 to the operator's taking and placing. The operator can directly send the film 2 into the accommodating space 111 through the open area jointly formed by the notch 1121 and the opening 1131. This setting further reduces the difficulty of taking out the film 2. Especially for the multi-layer stacked films 2, it is easier to take out the films 2 layer by layer or as a whole.
