Description

Technical Field

[0001] The utility model relates to a machine for opening a strip package, in particular a film taking machine. Background Art

[0002] The prior art WO2013101445A1 discloses a dispenser for opening a strip package. The dispenser includes a housing 20. A space 3 on the side of the housing is used to accommodate a transport container for the package, such as a paper box 2. The strip package 1 is peeled from the front of the container and is guided to still reach the separators 6, 7 in the form of a strip. The strip package 1 passes through the separators 6, 7. The separators include a pair of upper and lower rollers or pins arranged such that the strip package 1 passes through the nip between them. At the outlet of the nip area, the first and second films of the strip package are separated from each other and unfolded, and the envelopes of the strip package are opened one by one, and the items contained therein are released and provided in a gripping posture.

[0003] The separators are located on the front side of the container of the strip package. The receiver element 16 is located on the rear side of the strip package. The receiver element 16 is rotatably supported on the side of the housing. The films are respectively guided downstream along the upper wall part and the lower wall part that limit the space 3 or compartment for accommodating the container 2, and then are guided around the rollers or pins 12, 13, 14, 15 to the receiver element.

[0004] The receiver element rotates under the action of the control device, repeatedly holds and simultaneously winds the separated first and second films 10, 11 of the strip package on a single-axis body, and simultaneously applies a pulling force on these two films, pulls the strip package out of the container at the front, and separates it at the separator.

[0005] In this dispenser, since the separators and the receiver element are respectively arranged on both sides in the horizontal direction of the container, and a certain installation and operation space must be reserved between any two adjacent ones, the length occupied by the three in the horizontal direction is relatively large, and the volume of the occupied space is also relatively large. Moreover, there are also rollers or pins 12, 13, 14, 15 behind the receiver element, which further increases the lateral length of the dispenser, making the overall length of the dispenser large and the overall volume relatively large, bringing inconvenience to transportation, and the user also needs to provide a relatively large placement space for it. Summary of the Utility Model

[0006] The purpose to be achieved by the utility model is to provide a film taking machine, which solves the problem of inconvenience in transportation, packaging or storage caused by the too long overall length of the machine, effectively shortens the length of the machine, has a more compact structure, and is more convenient for transportation, packaging, carrying and storage.

[0007] To achieve the above object, the utility model adopts the following technical solutions: A film taking machine, comprising a machine body, a container mounting table, a separating member, a first winding member and a second winding member arranged on one side surface of the machine body, wherein:

[0008] The container mounting table is used for mounting a container with a strip-shaped package stored therein;

[0009] The separating member is used for separating a first film and a second film of the strip-shaped package;

[0010] The first winding member is used for winding the first film, and the second winding member is used for winding the second film;

[0011] The separating member is located on the horizontal side of the container mounting table;

[0012] A winding space is defined horizontally between the separating member and the container mounting table. The first winding member and the second winding member are located in the winding space. The first winding member is higher than the separating member, and the second winding member is lower than the separating member;

[0013] The separating member includes a first separating member and a second separating member distributed vertically. On the side away from the container mounting table between the first separating member and the second separating member, an outlet for outputting the strip-shaped package is formed. The horizontal plane where the outlet is located divides the winding space into a first winding space and a second winding space distributed vertically. The first winding member is located in the first winding space, and the second winding member is located in the second winding space;

[0014] A space for the first film to extend is formed between the first separating member and the first winding member. The first film extends to the first winding member through the first separating member. A space for the second film to extend is formed between the second separating member and the second winding member. The second film extends to the second winding member through the second separating member.

[0015] After adopting the above technical solution, the utility model has the following advantages: A winding space is defined in the horizontal direction between the separating member and the container mounting table, and is divided into a first winding space and a second winding space which are distributed up and down. The first winding member is located in the first winding space, and the second winding member is located in the second winding space. That is, the winding space between the container mounting table and the separating member is used to install the first winding member and the second winding member and supply the first film and the second film to extend and wind. The winding space between the container mounting table and the separating member is fully utilized, and the overall length occupied by the container mounting table, the first winding member, the second winding member and the separating member in the horizontal direction is greatly shortened, making the overall structure of the film taking machine more compact and more convenient for transportation, packaging, carrying and storage. More importantly, since the first winding member and the second winding member are located in the winding space between the separating member and the container mounting table, the distances between the first winding member and the second winding member and the separating member and the container mounting table in the horizontal direction are closer. The first film and the second film extending from the container opening pass through the separating member, and the lengths of the films extending to the two winding members are shorter and spread more smoothly. The acting forces of the first winding member and the second winding member on the first film and the second film are more direct and stable respectively. Therefore, the first film and the second film can be pulled out more stably and smoothly by the two winding members without jamming, and the winding effect is more stable.

[0016] Further, the first winding member includes a first winding shaft, the axis of the first winding shaft is parallel to the axis of the first separating member and determines a first plane, the first plane is inclined relative to the vertical plane, the second winding member includes a second winding shaft, the axis of the second winding shaft is parallel to the axis of the second separating member and determines a second plane, and the second plane is inclined relative to the vertical plane.

[0017] Adopting the foregoing technical solution, both the first plane and the second plane are inclined relative to the vertical plane, which is convenient for more smoothly pulling out the strip packaging and ensuring that the first film and the second film are separated when output at the outlet of the separating member.

[0018] Further, the angle A at which the first plane is inclined relative to the vertical plane is 15° to 75°; and / or, the angle B at which the second plane is inclined relative to the vertical plane is 15° to 75°.

[0019] Adopting the foregoing technical solution, by reasonably designing the magnitudes of the angles A and B, it is ensured that the first film and the second film can be smoothly pulled out and separated from the outlet.

[0020] Further, the second winding shaft is closer to the separating member in the horizontal direction than the first winding shaft, and the first winding shaft is closer to the separating member in the vertical direction than the second winding shaft.

[0021] Adopting the foregoing technical solution, A and B can be made unequal, so that the first film and the second film are subjected to different pulling forces from the first winding member and the second winding member, which is conducive to separating them while being output from the outlet; the second winding shaft is closer to the separating member in the horizontal direction than the first winding shaft, which can make full use of the vertical space of the second winding space and make the second film extend and wind more smoothly. The first winding shaft is closer to the separating member in the vertical direction than the second winding shaft, which can make full use of the horizontal space of the first winding space and is beneficial to reducing the height dimension of the whole machine.

[0022] Further, the axis of the first winding shaft is parallel to the axis of the second winding shaft and determines a third plane. The third plane is inclined relative to the vertical plane, and the inclination angle C is 2° to 10°.

[0023] Adopting the foregoing technical solution, by reasonably designing the size of the angle C, the position arrangement of the first winding member and the second winding member is further optimized, and the utilization rate of the winding space is improved.

[0024] Further, a guiding member is provided on the side surface of the machine body between the separating member and the container mounting table. The guiding member is used to guide the strip-shaped package to extend from the container to the separating member.

[0025] Adopting the foregoing technical solution, the smoothness and stability of the strip-shaped package extending from the container to the separating member can be improved, which is beneficial to the first film and the second film being smoothly separated at the outlet of the separating member.

[0026] Further, the guiding member includes a longitudinally extending portion connected to the container mounting table, a laterally extending portion connected to the separating member, and a guiding portion connected between the longitudinally extending portion and the laterally extending portion.

[0027] Adopting the foregoing technical solution is beneficial to improving the structural strength of the guiding member and providing complete support for the movement process of the strip-shaped package extending from the container to the separating member. The first film and the second film are laid out and extended from the container to the separating member in a flat state, and the materials in the strip-shaped package are prevented from being bent.

[0028] Further, the longitudinally extending portion and the container mounting table are of an integrally formed structure; and / or, one end of the laterally extending portion away from the guiding portion extends to the second separating member.

[0029] Adopting the foregoing technical solution, the integrally formed structure of the longitudinally extending portion and the container mounting table can improve the structural strength of the guiding member and facilitate the smooth guiding of the strip-shaped package; one end of the laterally extending portion away from the guiding portion extends to the second separating member, which can make the strip-shaped package transition to the second separating member more naturally and reduce the possibility of the materials being bent during the movement of the strip-shaped package.

[0030] Further, a limiting member for restricting the movement of the strip packaging along the guiding member is provided above the guiding member. A slit for the strip packaging to pass through is formed between the limiting member and the guiding member, and the limiting member is hinged to the machine body or the first separating member.

[0031] With the foregoing technical solution, through the slit formed between the limiting member and the guiding member, it can be ensured that the strip packaging moves flatly to the outlet, further reducing the possibility of material bending. The limiting member is hinged to the machine body or the first separating member, which is convenient for opening the slit and reinstalling a new strip packaging.

[0032] Further, a second tension shaft for increasing the tension of the second film is provided on the side of the machine body. The second tension shaft is located between the second separating member and the second winding member and within the second winding space. The second tension shaft is obliquely and upwardly offset relative to the second plane, and the second film moves along the outer circumferential surface of the second tension shaft; and / or, a first tension shaft for increasing the tension of the first film is provided on the side of the machine body. The first tension shaft is located between the first separating member and the first winding member and within the first winding space. The first tension shaft is obliquely and downwardly offset relative to the first plane, and the first film moves along the outer circumferential surface of the first tension shaft.

[0033] With the foregoing technical solution, the second tension shaft can increase the tension of the second film, ensuring smooth pulling of the second film without jamming and easy separation from the first film; similarly, the first tension shaft can increase the tension of the first film, ensuring smooth pulling of the first film without jamming and easy separation from the second film.

[0034] Further, a control module is provided inside the machine body. A detection shaft is provided on the side of the machine body between the separating member and the second winding member. The second film moves along the outer circumferential surface of the detection shaft to the second winding member. Spaces for the second film to extend are formed between the detection shaft and the separating member and the second winding member respectively. The detection shaft is provided with a detection sensor for detecting the moving distance of the second film, and the detection sensor is electrically connected to the control module.

[0035] With the foregoing technical solution, the control module and the detection sensor can be used to electrically control the pulling length of the strip packaging. The detection signal generated when the second film passes through the detection sensor is used to judge the pulling length of the second film, so as to control the states of the first winding shaft and the second winding shaft, whether to continue rotating or stop rotating. In addition, the detection shaft can also be used to increase the tension of the second film, ensuring that the second film is not prone to slip relative to the detection shaft, thereby improving the detection accuracy.

[0036] Further, the detection sensor is provided inside the detection shaft, and a detection window is provided on the outer circumferential surface of the detection shaft. The detection sensor detects the second film through the detection window; and / or, the detection shaft is located inside or outside the second winding space.

[0037] With the foregoing technical solution, the detection sensor is embedded in the detection shaft, with a hidden design, long service life, and it does not affect the extension and winding of the second film; the detection shaft is located within the second winding space, which can reduce the impact of the setting of the detection shaft on the lateral length of the machine. If the detection shaft is located outside the second winding space, the length of the second film from the outlet to the second winding shaft can be increased, facilitating the detection and identification by the detection sensor.

[0038] Furthermore, a second tension shaft for improving the tension of the second film is provided on the side of the machine body. The second tension shaft is located between the separation member and the detection shaft and within the winding space. The second tension shaft is higher than the detection shaft and closer to the container mounting table than the detection shaft. A space for the extension of the second film is formed between the second tension shaft and the detection shaft, and the second film moves along the outer circumferential surface of the second tension shaft to the detection shaft.

[0039] With the foregoing technical solution, the second tension shaft cooperates with the detection shaft to improve the tension of the second film, ensuring that the second film is not prone to slipping relative to the detection shaft, and ensuring that the detection sensor can accurately obtain the moving distance of the second film.

[0040] Furthermore, a film outlet sensor for obtaining the input signal of the user is provided inside the machine body. The film outlet sensor is located on the side of the separation member in the horizontal direction away from the container mounting table, and the detection direction of the film outlet sensor faces the side of the machine body where the separation member is located.

[0041] With the foregoing technical solution, an induction signal is obtained by the film outlet sensor, and the first winding member and the second winding member are controlled to work by using the induction signal, which can realize automatic film outlet, with diversified function selection and diversified working modes.

[0060] The technical solution of the present utility model will be described in detail below with specific embodiments. These several specific embodiments can be combined or replaced according to actual situations. For the same or similar concepts or processes, they may not be repeated in some embodiments.

[0061] As Figures 1 to 3 shown, the present utility model provides a film taking machine, which includes a machine body 100, a container mounting table 200, a separating member 300, a first winding member 400, and a second winding member 500 provided on one side surface of the machine body 100, wherein:

[0062] The container mounting table 200 is used to mount a container 20 storing a strip-shaped package 900. The container 20 generally adopts a rectangular parallelepiped or cube-shaped box structure. Therefore, the container mounting table 200 generally can adopt a structure with side plates 21 on all four sides, a bottom plate at the bottom, and an open top, which is convenient for mounting the container 20. Since the container mounting table 200 is fixed to one side surface of the machine body 100, the side surface of the machine body 100 can be used as a side plate. The height of the side plate 21 only needs to play a role in limiting the container 20 so that the container 20 is not easily detached from the container mounting table 200. The two adjacent side plates 21 can be connected or not. When connected, the structural strength is higher. When not connected, the corners of the container 20 can be avoided, which is convenient for taking and placing the container 20. It can be understood that the shape or structure of the container mounting table 200 can also be adjusted adaptively according to the shape of the container 20.

[0063] The separating member 300 is used to separate the first film 901 and the second film 902 of the strip-shaped package 900. The separating member 300 should facilitate the first film 901 and the second film 902 to change the extension direction. In order to reduce the length dimension of the film taking machine, the separating member 300 is located on the horizontal side of the container mounting table 200;

[0064] A winding space is defined horizontally between the separating member 300 and the container mounting table 200. The first winding member 400 and the second winding member 500 are located within the winding space. The first winding member 400 is higher than the separating member 300, and the second winding member 500 is lower than the separating member 300. Specifically, the separating member 300 includes a first separating member 31 and a second separating member 32 distributed vertically. On the side away from the container mounting table 200 between the first separating member 31 and the second separating member 32, an outlet 301 for outputting the strip-shaped package 900 is formed. The horizontal plane where the outlet 301 is located divides the winding space into a first winding space 101 and a second winding space 102 distributed vertically. The strip-shaped package 900 itself has a certain thickness. Since the outlet 301 naturally has a certain height, the horizontal plane where the outlet 301 is located includes all the horizontal planes that intersect perpendicularly with the longitudinal section of the outlet, that is, all the horizontal planes passing through the outlet 301 can be used as the horizontal boundary between the first winding space 101 and the second winding space 102. The first winding member 400 is located in the first winding space 101, and the second winding member 500 is located in the second winding space 102. The first separating member 31 and the second separating member 32 can adopt a common shaft structure or a curved plate structure with a relatively smooth surface, such as Figure 5 shown in

[0065] The winding space can be understood in combination with Figure 4 . First, the vertical plane where the right side surface of the container mounting table 200 is located defines the left boundary of the winding space, and the vertical plane where the separating member 300 is located defines the right boundary of the winding space. The vertical distance from the first winding member 400 to the separating member 300 limits the maximum diameter of the first film 901 during winding, so that the upper boundary of the first winding space 101 can be determined. The horizontal distance from the second winding member 500 to the right side surface of the container mounting table 200 limits the maximum diameter of the second film 902 during winding. At the same time, the vertical distance from the second winding member 500 to the table surface of the placing body 100 also limits the maximum diameter of the second film 902 during winding. It can be basically determined that the lower boundary of the second winding space generally does not exceed the bottom surface of the body or the table surface of the placing body 100, so as to clarify the spatial ranges of the first winding space 101 and the second winding space 102, which are respectively Figure 4 the two basic spaces outlined by the double-dot dash lines in. The first winding space 101 and the second winding space 102 are distributed vertically at different heights and are basically side by side horizontally, so that the length of the body 100 in the horizontal direction can be effectively shortened;

[0066] The first winding member 400 is used for winding the first film 901, and the second winding member 500 is used for winding the second film 902; the first winding member 400 and the second winding member 500 generally rotate synchronously. The first winding member 400 and the second winding member 500 can be manually driven. For example, a rotating handle can be added to drive the rotation of the first winding member 400 and the second winding member 500, which is relatively free to control. They can also be electrically driven. For example, a motor can be added to drive the rotation of the first winding member 400 and the second winding member 500. The motor can be manually controlled through a switch or automatically controlled through a sensor, which will be specifically described later.

[0067] A space for the first film 901 to extend is formed between the first separating member 31 and the first winding member 400, that is, there is enough distance between the first separating member 31 and the first winding member 400 for the first film 901 to extend, which is convenient for the separation of the first film 901 and the second film 902. The first film 901 extends to the first winding member 400 through the first separating member 31. A space for the second film 902 to extend is formed between the second separating member 32 and the second winding member 500. Similarly, there is enough distance between the second separating member 32 and the second winding member 500 for the second film 902 to extend, which is convenient for the separation of the second film 902 and the first film 901. The second film 902 extends to the second winding member 500 through the second separating member 32. It is necessary to ensure that the first film 901 and the second film 902 are respectively tensioned by the first winding member 400 and the second winding member 500, and a synchronous traction force is maintained on the first film 901 and the second film 902, which is beneficial to the smooth output of the strip packaging 900.

[0068] In summary, by defining a winding space in the horizontal direction between the separation member 300 and the container mounting table 200 and dividing it into an upper first winding space 101 and a lower second winding space 102, the first winding member 400 is located in the first winding space 101, and the second winding member 500 is located in the second winding space 102. That is, the winding space in the horizontal direction between the container mounting table 200 and the separation member 300 is used to install the first winding member 400 and the second winding member 500 and to extend and wind the first film 901 and the second film 902, making full use of the winding space in the horizontal direction between the container mounting table 200 and the separation member 300. The overall length occupied by the container mounting table 200, the first winding member 400, the second winding member 500, and the separation member 300 in the horizontal direction is greatly shortened, making the overall structure of the film taking machine more compact and more convenient for transportation, packaging, carrying, and storage.

[0069] More importantly, since the first winding member 400 and the second winding member 500 are located in the winding space between the separating member 300 and the container mounting table 200, the horizontal distances between the first winding member 400 and the second winding member 500 and the separating member 300 and the container mounting table 200 are closer. The first film 901 and the second film 902 extending from the container opening pass through the separating member 300, and the lengths of the films extending to the two winding members are shorter and spread flatter. The acting forces of the first winding member 400 and the second winding member 500 on the first film 901 and the second film 902 are more direct and stable. Therefore, the first film 901 and the second film 902 can be pulled out by the two winding members more stably and smoothly without jamming, and the winding effect is more stable.

[0070] In one embodiment, in order to make the separation of the first film 901 and the second film 902 smoother, it can be designed that the first winding member 400 includes a first winding shaft 41. The axis of the first winding shaft 41 is parallel to the axis of the first separating member 31 and determines a first plane M1. The first plane M1 is inclined relative to the vertical plane. The second winding member 500 includes a second winding shaft 51. The axis of the second winding shaft 51 is parallel to the axis of the second separating member 32 and determines a second plane M2. The second plane M2 is inclined relative to the vertical plane. Both the first plane M1 and the second plane M2 are inclined relative to the vertical plane so as to be able to pull out the strip packaging 900 more smoothly and ensure that the first film 901 and the second film 902 are effectively separated while being pulled out at the outlet 301 of the separating member 300. Since both the first winding shaft 41 and the second winding shaft 51 are located in the winding space, that is, on the left side in the horizontal direction of the separating member 300, the first film 901 and the second film 902 are separated at a large angle after being pulled out from the outlet 301, which is convenient for the user to obtain the material.

[0071] It should be noted that generally, the material is a circular filter membrane. Both the first film 901 and the second film 902 are composed of multiple sections connected in series with equal lengths. The starting points and ending points of each section of the two correspond. Each section of the first film 901 and the second film 902 wraps a filter membrane. The filter membrane is not adhered to the first film 901 nor to the second film 902. Only the four sides of each section are adhered and sealed to seal the filter membrane and prevent it from being contaminated.

[0072] Under the pulling action of the first winding member 400 and the second winding member 500 respectively, each section of the first film 901 and the second film 902 gradually outputs from the outlet 301 of the separating member 300. The output part is separated at the outlet 301, that is, the four sides of each section are gradually separated. The first winding member 400 and the second winding member 500 continue to rotate, and the first film 901 and the second film 902 of this section continue to output and separate from the outlet. The filter membrane wrapped in this section also begins to extend from the outlet 301. When the extended length is long enough, the user can take away the filter membrane.

[0073] The angle A at which the first plane M1 is inclined relative to the vertical plane is 15° to 75°, for example, A = 15°, 30°, 47°, 60° or 75°, etc. Similarly, the angle B at which the second plane M2 is inclined relative to the vertical plane is 15° to 75°, for example, B = 15°, 21°, 45°, 60° or 75°, etc. A and B can be equal or unequal. By reasonably designing the magnitudes of angles A and B, it is ensured that the first film 901 and the second film 902 can be smoothly pulled out and separated from the outlet 301, and at the same time, good tension effects of the first film 901 and the second film 902 can be ensured.

[0074] In one embodiment, it can be designed that the second winding shaft 51 is closer to the separating member 300 in the horizontal direction than the first winding shaft 41, and the first winding shaft 41 is closer to the separating member 300 in the vertical direction than the second winding shaft 51. In this way, angles A and B can be made unequal, so that the pulling forces on the first film and the second film by the first winding member and the second winding member are different, which is beneficial to their separation while being output from the outlet. The second winding shaft 51 being closer to the separating member 300 in the horizontal direction than the first winding shaft 41 can make full use of the vertical space of the second winding space 102, making the extension and winding of the second film 902 smoother. The first winding shaft 41 being closer to the separating member 300 in the vertical direction than the second winding shaft 51 can make full use of the horizontal space of the first winding space, which is beneficial to reducing the height dimension of the whole machine.

[0075] As the usage time increases, the first film 901 will be continuously wound on the first winding shaft 41, and the second film 902 will be continuously wound on the second winding shaft 51. Therefore, the weight distribution of the whole machine changes. Since the second film 902 is wound in the second winding space 102, it generally will not cause the overall center of gravity of the machine to rise. However, the first film 901 is wound in the first winding space 101, which is higher than the space where the container is located. Therefore, it will cause a certain degree of rise in the overall center of gravity of the machine. Therefore, in order to improve the stability of the machine during use, in one embodiment, the axis of the first winding shaft 41 is parallel to the axis of the second winding shaft 51 to determine the third plane M3. The third plane M3 is inclined relative to the vertical plane, and the inclination angle C is 2° to 10°, for example, 2°, 4°, 5°, 7°, 10°, etc. By reasonably designing the magnitude of angle C, the position arrangement of the first winding member and the second winding member is further optimized, and the utilization rate of the winding space is improved. At the same time, the center of gravity of the first winding shaft 41 after winding the first film 901 can be made to be horizontally located between the center of gravity of the container and the center of gravity of the second winding shaft 51 after winding the second film 902, so that the overall center of gravity of the machine is balanced at a relatively central position in the length direction of the machine body, thereby improving the stability of the machine during use.

[0076] To improve the smoothness and stability of the strip packaging 900 extending from the container to the separating member 300, a guiding member 600 can be provided on the side of the machine body 100 between the separating member 300 and the container mounting table 200. The guiding member 600 is used to guide the strip packaging 900 from the container to the separating member 300, and is also beneficial to the smooth separation of the first film 901 and the second film 902 at the outlet 301 of the separating member 300.

[0077] The guiding member 600 has a continuous surface for supporting the movement of the strip packaging 900, ensuring that the material is not easily bent during movement. Specifically, in one embodiment, the guiding member 600 includes a longitudinally extending portion 61 connected to the container mounting table 200, a laterally extending portion 62 connected to the separating member 300, and a guiding portion 63 connected between the longitudinally extending portion 61 and the laterally extending portion 62. Since the guiding member 600 can be fixed to the machine body 100, the structural strength of the guiding member 600 and the stability after fixation can be improved through the longitudinally extending portion 61 and the laterally extending portion 62. The longitudinally extending portion 61 extends upward from the bottom, enabling the strip packaging 900 to be supported as it leaves the container. The guiding portion 63 allows the strip packaging 900 to be smoothly transferred onto the laterally extending portion 62. The guiding portion 63 can adopt a curved surface structure convex toward the side where the strip packaging 900 is located, or a bevel structure, with both ends smoothly connected to the longitudinally extending portion 61 and the laterally extending portion 62 respectively. The first film 901 and the second film 902 are spread out from the container in a flat state, extended to the separating member 300, and the material inside the strip packaging is prevented from being bent.

[0078] To further improve the structural strength of the guiding member 600, the longitudinally extending portion 61 and the container mounting table 200 can be designed as an integrally formed structure, that is, the bottom plate of the container mounting table 200 and the longitudinally extending portion 61 are an integral structure, and the longitudinally extending portion 61 is a vertically extending plate-like structure, facilitating the smooth guiding of the strip packaging. When fixing the container mounting table 200, the guiding member 600 is fixed simultaneously. For example, connecting ears 64 are provided on the side of the longitudinally extending portion 61 facing away from the container mounting table 200 and on the side of the guiding member 600 facing away from the strip packaging 900. The connecting ears 64 are fixedly connected to the machine body 100 through fasteners, thereby fixedly connecting the container mounting table 200 to the side wall of the machine body 100.

[0079] In order to enable the strip packaging 900 to smoothly transition to the outlet 301, one end of the lateral extension 62 away from the guiding part 63 extends to the second separating part 32, reducing the possibility of the material being bent and damaged during the movement along with the strip packaging. A small gap can be left between the lateral extension 62 and the second separating part 32. For example, when the second separating part 32 needs to rotate, it is inconvenient for the lateral extension 62 to directly contact the second separating part 32. And when the second separating part 32 does not rotate, the lateral extension 62 can also directly contact the second separating part 32, or even be manufactured as an integral structure.

[0080] Generally, the strip packaging 900 is tensioned on the guiding part 600 to ensure that the strip packaging 900 does not bend during transportation. In order to prevent foreign objects from falling and hitting the strip packaging 900, a limiting part 700 for restricting the movement of the strip packaging 900 along the guiding part 600 can be provided above the guiding part 600. A slit for the strip packaging 900 to pass through is formed between the limiting part 700 and the guiding part 600. The limiting part 700 is hinged to the machine body 100 or the first separating part 31. Through the slit formed between the limiting part 700 and the guiding part 600, it can be ensured that the strip packaging 900 moves smoothly to the outlet 301, further reducing the possibility of the material being damaged. The limiting part 700 is hinged to the machine body 100 or the first separating part 31, which is convenient for opening the slit and reinstalling a new strip packaging 900.

[0081] In order to improve the tension of the second film 902, a second tension shaft 12 for improving the tension of the second film 902 can be provided on the side of the machine body 100. The second tension shaft 12 is located between the second separating part 32 and the second winding part 500 and is within the second winding space 102. The second tension shaft 12 is obliquely displaced upward relative to the second plane M2, and the second film 902 moves along the outer circumferential surface of the second tension shaft 12. Similarly, in order to improve the tension of the first film 901, a first tension shaft (not shown in the figure) for improving the tension of the first film 901 can also be provided on the side of the machine body 100. The first tension shaft is located between the first separating part 31 and the first winding part 400 and is within the first winding space 101. The first tension shaft is obliquely displaced downward relative to the first plane M1, and the first film 901 moves along the outer circumferential surface of the first tension shaft. Ensure that the second film 902 and the first film 901 are pulled out smoothly without jamming, and the two are separated in time at the outlet 301, and the material is smoothly output from the outlet 301.

[0082] In another embodiment, a control module is provided inside the body 100. A detection shaft 13 is provided between the separation member 300 and the second winding member 500 on the side of the body 100. The second film 902 moves along the outer circumferential surface of the detection shaft 13 to the second winding member 500. Spaces for the second film 902 to extend are formed between the detection shaft 13 and the separation member 300 and the second winding member 500 respectively. The detection shaft 13 is provided with a detection sensor for detecting the moving distance of the second film 902, and the detection sensor is electrically connected to the control module. By using the control module and the detection sensor, the pulling-out length of the strip packaging 900 can be electrically controlled. The moving distance of the second film 902 is judged by the detection signal generated when the second film 902 passes through the detection sensor, so as to control the working states of the first winding shaft 41 and the second winding shaft 51, that is, to continue rotating or stop rotating. In addition, the detection shaft 13 can also be used to increase the tension of the second film 902, ensuring that the second film 902 is not likely to slip relative to the detection shaft 13, thereby improving the detection accuracy.

[0083] The detection sensor is arranged inside the detection shaft 13. A detection window 131 is provided on the outer circumferential surface of the detection shaft 13. The detection sensor detects the second film 902 through the detection window 131. The detection sensor is embedded in the detection shaft 13, with a hidden design, long service life, and does not affect the extension and winding of the second film 902. There are various ways for the detection sensor to detect the second film 902. For example, a mark is set at a fixed length interval on the second film 902. As the second film 902 is pulled and wound, each time the mark is detected, the detection sensor can generate a detection signal, thereby obtaining the moving distance of the second film 902. When the control module receives the signal, the first winding member 400 and the second winding member 500 pause rotating. During this process, the user completes an operation of obtaining materials, such as taking away the filter membrane with tweezers. Besides using marks, visual technology can also be used to automatically judge the moving distance of the second film. Then the first winding member 400 and the second winding member 500 rotate again to continue pulling out the next section of the first film 901 and the second film 902. To improve the degree of automation, on the basis of the motor driving the first winding member 400 and the second winding member 500, by operating the film outlet switch on the body 100, the control module obtains the film outlet signal and starts the first winding member 400 and the second winding member 500 again, that is, the semi-automatic film outlet mode of the film taking machine.

[0084] Among them, the marks on the second film 902 can be color marks, and the detection sensor generates a detection signal through the difference between different colors, or can be light-transmitting marks, and the detection sensor generates a detection signal through the difference in light transmittance. For example, a through groove 921 can be directly provided on the second film 902. The through groove 921 will transmit light, while the position without the through groove 921 will block light to a certain extent. When the through groove 921 is aligned with the detection window 131, the detection sensor can generate a detection signal, and the control module causes the two winding members to stop rotating.

[0085] In one embodiment, the detection shaft 13 can be designed to be located within the second winding space 102, which can reduce the influence of the setting of the detection shaft 13 on the lateral length of the machine. In another embodiment, the detection shaft 13 can be designed to be located outside the second winding space 102, which can increase the length of the second film 902 from the outlet 301 to the second winding shaft 51 after being pulled out, facilitating the detection and identification by the detection sensor.

[0086] On the basis of setting the detection shaft 13, the tension of the second film 902 can be further increased. For example, a second tension shaft 12 for increasing the tension of the second film 902 is provided on the side of the machine body 100. The second tension shaft 12 is located between the separation member 300 and the detection shaft 13 and within the winding space. The second tension shaft 12 is higher than the detection shaft 13 and is closer to the container mounting table 200 than the detection shaft 13. A space for the second film 902 to extend is formed between the second tension shaft 12 and the detection shaft 13. The second film 902 moves along the outer circumferential surface of the second tension shaft 12 to the detection shaft 13. The second tension shaft 12 cooperates with the detection shaft 13 to increase the tension of the second film 902, ensuring that the second film 902 is not prone to slipping relative to the detection shaft 13 and ensuring that the detection sensor can accurately obtain the moving distance of the second film 902.

[0087] In order to further improve the degree of automation and reduce the operation steps of the user, a film outlet sensor 14 for obtaining the input signal of the user may also be provided in the machine body 100. The film outlet sensor 14 is located on the side of the separating member 300 in the horizontal direction away from the container mounting table 200, and the detection direction of the film outlet sensor 14 faces the side of the machine body 100 where the separating member 300 is located. The film outlet sensor 14 is located on the side of the separating member 300 in the horizontal direction away from the container mounting table 200. During the working process, when a certain filter membrane extends a certain length from the outlet 301, the detection sensor detects the signal and transmits it to the control module, which controls the first winding member 400 and the second winding member 500 to pause rotating. The user uses a clamping tool such as tweezers to pick up the material. The clamping tool will approach the outlet 301 of the separating member 300, and the clamping tool will be sensed by the film outlet sensor 14. The film outlet sensor 14 generates a sensing signal and transmits it to the control module. After receiving the sensing signal, the control module controls the first winding member 400 and the second winding member 500 to start rotating again and continue to discharge the film, realizing automatic film discharge, that is, the sensing film discharge mode of the film taking machine. By turning off the detection sensor, it is possible to return to the semi-automatic film discharge mode, with diverse working modes.

[0088] Since the materials in the strip packaging 900 are generally arranged in sequence along the length direction of the strip packaging 900, the film is generally discharged in an intermittent manner, that is, the first winding member 400 and the second winding member 500 work for a period of time to complete the film discharge, then pause for a period of time, and then continue to work after obtaining the film discharge signal (generated by the user operating the film discharge switch or obtained by the film outlet sensor sensing and transmitting), complete the next film discharge, and then pause for work, waiting for the next film discharge signal.

[0089] In addition to the above preferred embodiments, the present utility model has other implementation manners. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection claimed by the present utility model.
