Description

Technical Field

[0001] The invention relates to the technical field of film packaging equipment, in particular to a simple film packaging equipment for thin covers. Background Art

[0002] Some thin covers (referred to as "thin covers"), such as can covers, need to be stacked and wrapped with sanitary films to form can cover rollers before transportation, so as to reduce the contamination of the can covers during transportation. In the prior art, it is usually necessary to manually wrap a stack of can covers with sanitary films, which leads to a lot of uncontrollable human contact contamination on the can cover packaging line, increasing the risk of contamination of the can covers. In addition, the entire production and packaging line requires a large number of operators, with a low degree of automation, resulting in high production efficiency and cost.

[0003] To this end, the Chinese invention patent with application number CN201510276308.3 (authorization announcement number CN104859885B) discloses an automatic film packaging machine, including: a frame, as the main body of the packaging machine, used to support the following components; a counting and conveying assembly, arranged at the end of the frame, used to count a certain number of can lids, stack the counted can lids into a stack, and convey the stacked can lids to a designated position; a packaging assembly, arranged in the middle of the frame, used to package the stacked can lids to form a can lid roller wrapped with a sanitary film; a film conveying assembly, arranged in the middle of the frame , for the packaging assembly to convey the sanitary film required for the packaging process; the transport clamp assembly is arranged at the end of the frame, and one end is located on the upper part of the counting and conveying assembly, and the other end is located on the upper part of the packaging assembly, which is used to clamp the stacked can lids and transport them to the packaging assembly; the two-end welding assembly is arranged corresponding to the packaging assembly, and is used to weld and seal the films at both ends of the can lid roller after being wrapped by the packaging assembly; the roller conveying assembly is arranged in the middle of the frame, and is used to convey the can lid roller packaged by the packaging assembly to the two-end welding assembly; the roller output assembly outputs the can lid roller after being welded and sealed by the two-end welding assembly to the finished product stacking area. The automatic film packaging machine can not only significantly improve the automation degree of the can lid production line, save labor costs, and have significant economic benefits, but also greatly reduce the uncontrollable contact pollution caused by human beings, and improve health and safety.

[0004] However, the automatic film packaging machine in the above patent still has certain shortcomings. After the can lids are stacked into a pile by the counting and conveying assembly of the above packaging machine, they need to be clamped by the transport clamp assembly and transferred to the location of the packaging assembly. The transport action process of the transport clamp assembly is to drive the clamped can lids to perform multiple horizontal and vertical movements through the cooperation of the horizontal drag chain bracket and the vertical drag chain bracket of the clamp system to realize the transfer process of the can lids. The action process of the above transport clamp assembly is relatively complicated, the packaging efficiency is not high, and there is a risk of the clamp system not clamping firmly and falling. On the other hand, the setting of the above transport clamp assembly also makes the packaging machine occupy a larger space as a whole.

[0005] Therefore, the existing film packaging equipment for thin covers needs further improvement. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a simple film packaging device for thin covers which can effectively simplify the feeding process of stacked thin covers and thus improve the packaging efficiency in view of the current status of the prior art.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: a simple film packaging device for thin covers, comprising:

[0008] The rack has a first position, a second position and a third position, wherein the first position and the second position are respectively spaced apart along a first direction consistent with a transverse direction of the rack, and the second position and the third position are respectively spaced apart along a second direction consistent with a longitudinal direction of the rack;

[0009] A material guiding channel extends along the first direction of the frame to receive and place the thin cover transferred from the previous process;

[0010] A transverse material pushing mechanism, provided on the frame, for pushing the thin covers stacked together standing in the material guiding channel from a first position to a second position;

[0011] a longitudinal material pushing mechanism, arranged at the second position of the frame, having a thin cover clamping channel which can be connected with the material guiding channel and can be opened and closed up and down, for receiving the stacked thin covers pushed by the transverse material pushing mechanism, and driving the stacked thin covers in the thin cover clamping channel to be pushed from the second position of the frame to the third position of the frame, and opening the thin cover clamping channel to release the stacked thin covers;

[0012] The film wrapping device is arranged on the frame, and includes a film conveying mechanism and a heat cutting mechanism. The film conveying mechanism can convey the film to the area of ​​the forward path of the longitudinal pushing mechanism and arrange the film in the area vertically, and can be pressed by the longitudinal pushing mechanism during the forward movement of the longitudinal pushing mechanism to release the film required for packaging; the heat cutting mechanism is arranged at the third position of the frame, and is used to wrap the film on the outer periphery of the stacked thin covers and cut off the excess film after wrapping, so as to form a thin cover roller preliminarily wrapped with the film;

[0013] A roller conveying mechanism is arranged on the frame and runs in a circuitous manner in the second direction of the frame, and is used to convey the thin cover roller wrapped with the film;

[0014] The heat shaping mechanism is arranged on the frame and is used for performing heat shaping treatment on the films at both ends of the thin cover roller and the films wrapped on the outer periphery of the thin cover roller.

[0015] In order to drive the stacked thin covers to move smoothly in the first direction of the frame, the lateral pushing mechanism includes:

[0016] A slide assembly, comprising a slide rail extending along a first direction of the frame and a slide seat slidably arranged on the slide rail, wherein the slide rail has a first rotation axis consistent with its own length direction, and the slide rail is connected to the frame in a manner of being rotatable around the first rotation axis;

[0017] A material push baffle unit is arranged on the sliding seat, comprising a material push plate, which can rotate with the slide rail and has a material push state in which the material push plate is located above the material guide channel and abuts against the thin cover placed on the material guide channel, and a yield state in which the material push plate is away from the material guide channel and outside the moving path of the thin cover;

[0018] The first driving mechanism is arranged on the frame, and a power output end of the first driving mechanism is connected to the slide rail to drive the slide rail to rotate around the first rotation axis.

[0019] When the lateral pushing mechanism starts to push forward, in order to prevent the thin cover subsequently transferred to the material guide channel from falling forward, the pushing baffle unit includes a thin cover buffer device, which includes:

[0020] A support plate assembly, comprising a first support plate and a second support plate spaced apart along the first direction on the sliding seat, wherein the first support plate is disposed adjacent to a first position of the frame, and the second support plate is disposed away from the first position of the frame;

[0021] A guide rod is movably arranged on the first support plate and the second support plate along its own axial direction, the axial direction of the guide rod is consistent with the first direction of the frame, the guide rod has a first end adjacent to the first support plate and a second end adjacent to the second support plate, and the second end of the guide rod is connected to the push plate;

[0022] The elastic member acts on the guide rod and makes the second end of the guide rod always have a tendency to move toward the first supporting plate.

[0023] With the cooperation of the elastic member and the push plate, the thin cover subsequently transmitted to the material guide channel will resist the push plate and compress the elastic member. Therefore, even when the push plate starts to push forward, the subsequent thin cover will not fall forward. This achieves the simplification of the lateral pushing mechanism while ensuring the stability of the thin cover transmission process.

[0024] The above-mentioned elastic member can adopt various existing technologies and may include various elastic elements such as compression springs, torsion springs, and spring leaves. However, in order to better cooperate with the above-mentioned guide rod structure, the outer peripheral surface of the guide rod has a radially outwardly protruding block, and the elastic member is a spring sleeved on the guide rod, which is correspondingly located between the block and the second support plate.

[0032] In order to keep the stacked thin covers conveyed to the thin cover clamping channel through the material guiding channel in an upright state and avoid tipping over, a brush is provided on the inner wall surface of the pressing plate to keep the stacked thin covers pushed into the thin cover clamping channel through the lateral material pushing mechanism in an upright state.

[0033] A brush is arranged on the inner wall surface of the pressing plate. On the one hand, it can enable the stacked thin covers that are transferred to the thin cover clamping channel through the material guiding channel to remain in an upright state. On the other hand, it also makes the reserved gap between the pressing plate and the supporting plate (in a closed state) relatively large (slightly larger than the outer diameter of the thin cover) to avoid interference with the process of the thin cover entering the thin cover clamping channel or the forward movement of the pushing plate.

[0034] In order to realize the opening and closing action between the pressure plate and the support plate, a connecting seat is provided at the power output end of the second driving mechanism, and the thin cover clamping device is arranged on the connecting seat, wherein the pressure plate of the thin cover clamping device is rotatably connected to the connecting seat, and the power output end of the third driving mechanism is connected to the pressure plate and can drive the pressure plate to rotate relative to the connecting seat.

[0037] The mobile frame driving mechanism includes a fourth driving mechanism and a fifth driving mechanism. The power output end of the fourth driving mechanism is connected to the first mobile frame, and the fifth driving mechanism is connected to the second mobile frame.

[0038] In order to flexibly release the film required in the thin cover wrapping process, the film conveying mechanism includes:

[0039] A first film unwinding assembly includes a first film fixing roll for winding a film, a first film tensioning roller assembly for laying the film, and a sixth driving mechanism for driving the first film fixing roll to rotate around its own axis to release the film;

[0040] The second film unwinding assembly is located above the first film unwinding assembly and includes a second film fixing roll for winding the film, a second film tensioning roller assembly for laying the film, and a seventh driving mechanism for driving the second film fixing roll to rotate around its own axis to release the film.

[0041] In order to achieve the purpose of accurate film supply of the film conveying mechanism, the first film tensioning roller assembly at least includes two first brackets, a first tensioning roller and a first proximity switch, the two first brackets are vertically arranged and spaced apart in the first direction of the frame, and two first slide grooves arranged vertically are provided on the two opposite surfaces of the two first brackets, and the two ends of the first tensioning roller can be correspondingly slid up and down in the first slide grooves on the two first brackets, and the first tensioning roller tensions the film laid on the first film tensioning roller assembly under the action of its own gravity, and the first proximity switch is arranged on the first bracket, for identifying when the first tensioning roller moves up to a set position, and outputs a signal to start the sixth driving mechanism to the control system to release the film wound on the first film fixed roll;

[0042] The second film tensioning roller assembly includes at least two second brackets, a second tensioning roller and a second proximity switch. The two second brackets are vertically arranged and spaced apart in the first direction of the frame. Two second brackets opposite to each other are provided with vertically arranged second slide grooves. Both ends of the second tensioning roller can be slid up and down in the second slide grooves on the two second brackets accordingly. The second tensioning roller tensions the film laid on the second film tensioning roller assembly under the action of its own gravity. The second proximity switch is arranged on the second bracket for identifying when the second tensioning roller moves up to a set position and outputs a signal to start the seventh drive mechanism to the control system to release the film wound on the second film fixed roll.

[0043] In order to realize the transmission of the thin cover roller with the preliminary film completed, the roller transmission mechanism includes a rotating roller assembly that can rotate cyclically in the second direction of the frame, and the rotating roller assembly includes a plurality of rotating rollers arranged in sequence and spaced apart in the second direction of the frame, and any two adjacent rotating rollers form a positioning position for positioning and upwardly supporting the thin cover roller, and each of the rotating rollers can also rotate around its own axis to drive the thin cover roller placed on the positioning position to rotate around its own axis.

[0044] In order to perform shaping and shrinking treatment on the end and peripheral film of the thin cover roller to ensure the effect of thin cover film coating, the thermal shaping mechanism includes:

[0045] The port shaping device comprises a stand, hot air injection heads arranged at both ends of the stand, and two eighth driving mechanisms arranged on the stand, wherein the stand is located above the roller conveying mechanism and is extended along the first direction of the frame, the two hot air injection heads are slidably arranged on the stand, and can reciprocate along the length direction of the stand, and the power output ends of the two eighth driving mechanisms are respectively connected to the two hot air injection heads, so as to drive the two hot air injection heads to correspond to the port positions of the thin cover roller placed on the rotating roller assembly, and heat and shape the films at both ends of the thin cover roller;

[0046] The peripheral shaping device includes a hot air injection rack located above the roller conveying mechanism and extending along the first direction of the frame.

[0047] In order to simplify the structure of the thermal plastic forming mechanism and reduce the occupied space, the hot air injection rack is also arranged on the vertical rack.

[0048] Compared with the prior art, the advantages of the present invention are as follows: the loading process of the thin cover of the simple film packaging equipment for thin covers of the present invention is realized by the cooperation of the horizontal pushing mechanism and the longitudinal pushing mechanism, wherein the longitudinal pushing mechanism has a thin cover clamping channel, which can be directly used to receive the stacked thin covers pushed by the horizontal pushing mechanism, and drive the stacked thin covers to move along the second direction of the frame to the position where the film coating device is located for film coating operation. The film packaging equipment does not need to drive the clamped can cover to move horizontally and vertically multiple times through the handling clamp assembly in the prior art to realize the transfer of the thin cover (can cover), thereby effectively simplifying the loading process of the thin cover and improving the packaging efficiency. In the preferred embodiment, the thin cover clamping channel is formed by the cooperation of the pressure plate and the support plate of the thin cover clamping device to directly receive the stacked thin covers transmitted from the material guide channel of the horizontal pushing mechanism, wherein the pressure plate and the support plate clamp the outer periphery of the thin cover, which can effectively solve the problem of unreliable clamping of the handling clamp system (clamping at both ends of the thin cover stacking direction) in the prior art and avoid the risk of falling.

[0063] The present invention is further described in detail below with reference to the accompanying drawings.

[0064] See also Figure 1-Figure 14A simple film packaging device for thin covers includes a frame 10, a thin cover erecting device 30, a lateral pushing mechanism 20, a longitudinal pushing mechanism 40, a film wrapping device, a roller conveying mechanism 90 and a thermoplastic forming mechanism 91. The thin cover erecting device 30, the lateral pushing mechanism 20, the longitudinal pushing mechanism 40, the film wrapping device, the roller conveying mechanism 90 and the thermoplastic forming mechanism 91 are all arranged on the frame 10.

[0065] The rack 10 has a first position, a second position and a third position, wherein the first position and the second position are respectively along a first direction (eg, Figure 3 The second position and the third position are respectively arranged along a second direction (as shown in FIG. Figure 3 M2 in the figure); that is, the first direction is perpendicular to the second direction. In this embodiment, the thin cover is firstly transported from the first position to the second position along the first direction of the frame 10 by the transverse pushing mechanism 20, and then transported from the second position to the third position along the second direction of the frame 10 by the longitudinal pushing mechanism 40, and then wrapped with a film by the film wrapping device. After the initial wrapping is completed, it is continuously pushed forward along the second direction of the frame 10 by the roller conveying mechanism 90. During the movement, the thermoplastic mechanism 91 can heat and shrink the film that initially wraps the thin cover roller. After the treatment is completed, it can be continuously driven by the roller conveying mechanism 90 to the position of the unloading slide 11 provided on the frame 10 for unloading.

[0066] The frame is provided with a material guide channel 21, which extends along the first direction of the frame 10 and is used to receive and place the thin cover transferred from the previous process. The cross section of the material guide channel 21 is preferably designed to be C-shaped, and the opening is upward, wherein the inner diameter of the material guide channel 21 is adapted to the outer diameter of the thin cover so that the thin cover can be stably transferred in an upright state. The transverse material pushing mechanism 20 is used to push the thin covers 101 that are stacked together and stand upright in the material guide channel 21 from a first position to a second position along the first direction of the frame 10.

[0067] See also Figure 2 and Figure 4 The lateral pushing mechanism 20 includes a slide assembly, a pushing baffle unit 24 and a first driving mechanism 25. Figure 1 In the embodiment, the lateral pushing mechanism 20 is shielded by a protective cover. Figure 2 for Figure 1 Schematic diagram of the structure after hiding the protective cover and other components.

[0068] See also Figure 4The slide assembly includes a slide rail 22 extending along the first direction of the frame 10 and a slide seat 23 slidably arranged on the slide rail 22, wherein the slide rail 22 is arranged on one side of the material guide channel 21, that is, arranged in parallel with the material guide channel 21. Since the movement path of the thin cover in the first direction is relatively long, the slide rail 22 and the slide seat 23 of this embodiment preferably adopt a magnetic coupling rodless cylinder, wherein the cylinder body of the magnetic coupling rodless cylinder is equivalent to the above-mentioned slide rail 22, and the slider on the cylinder body of the magnetic coupling rodless cylinder is equivalent to the above-mentioned slide seat 23.

[0069] Continue to see Figure 4 The slide rail 22 of this embodiment has a first rotation axis 220 that is consistent with its length direction, and the slide rail 22 is connected to the frame 10 in a manner that it can rotate around the first rotation axis 220. Specifically, a first fixing seat 27 and a second fixing seat 28 fixed to the frame 10 are also arranged at intervals in the first direction of the frame 10, and the two ends of the slide rail 22 are rotatably connected to the first fixing seat 27 and the second fixing seat 28 through respective bearings.

[0070] See also Figure 4 The first driving mechanism 25 is disposed on the frame 10, and its power output end is movably connected to the slide rail 22, which can be realized by hinges or other means to drive the slide rail 22 to rotate around the first rotation axis 220. The first driving mechanism 25 of this embodiment can be a motor or a cylinder.

[0071] See also Figure 4 The push plate unit 24 includes a push plate 241 and a thin cover buffer device provided on the sliding seat 23. The thin cover buffer device specifically includes a support plate assembly, a guide rod 263 and an elastic member 265 (not shown in the figure). The support plate assembly includes a first support plate 261 and a second support plate 262 spaced apart along a first direction on the sliding seat 23. The first support plate 261 is provided at a first position adjacent to the frame 10, and the second support plate 262 is provided at a first position away from the frame 10. The guide rod 263 is movably provided on the first support plate 261 and the second support plate 262 along its own axial direction. The axial direction of the guide rod 263 is consistent with the first direction of the frame 10. The guide rod 263 has a first end adjacent to the first support plate 261 and a second end adjacent to the second support plate 262.

[0072] See also Figure 4The push plate 241 is connected to the second end of the guide rod 263, wherein the push plate 241 is a strip plate, and the push plate 241 can slide along the slide rail 22 with the sliding seat 23, and can also rotate with the rotation of the slide rail 22, so that the push plate has two states: a pushing state and a yielding state. In the pushing state, the free end of the push plate 241 is located above the material guide channel 21 and abuts against the thin cover placed on the material guide channel 21, so that the thin cover can be pushed to move when the sliding seat 23 moves forward. In the yielding state, the push plate 241 can be away from the top of the material guide channel 21 and outside the moving path of the thin cover, so that when the sliding seat 23 is reset, it will not interfere with the thin cover that is subsequently pushed to the port position of the material guide channel 21.

[0073] See also Figure 4 The outer peripheral surface of the guide rod 263 is provided with a stopper 264 protruding radially outward, and the elastic member 265 is a spring sleeved on the guide rod 263, one end of the spring abuts against the stopper 264, and the other end abuts against the second support plate 262, so that the second end of the guide rod 263 always has a tendency to move toward the first support plate 261. Of course, the elastic member can also be in the form of a tension spring, which can also achieve the above purpose.

[0074] With the cooperation of the elastic member 265 and the pushing plate 241, the thin cover subsequently transmitted to the material guide channel 21 will abut against the pushing plate 241 and compress the elastic member 265. Therefore, even when the pushing plate 241 starts to push forward, the subsequent thin cover will not fall forward. This ensures the stability of the thin cover transmission process while simplifying the lateral pushing mechanism 20.

[0075] For the simple film packaging equipment for thin covers, the previous process of the lateral pushing mechanism 20 is basically to use a transmission belt (not shown) to convey the flat thin cover to the end position of the material guide channel 21. In order to connect with the transmission belt and achieve the purpose of standing up the thin cover and keeping it in the standing state, a thin cover standing device 30 is set at the end position of the material guide channel. The thin cover standing device 30 includes a magnetic wheel assembly and a thin cover holding assembly, wherein the magnetic wheel assembly includes a magnetic wheel 31 arranged at the end position of the material guide channel 21, the axis of the magnetic wheel 31 is perpendicular to the length direction of the material guide channel 21, and the magnetic wheel 31 is connected to a driving member and can rotate around its own axis (the driving member can be a motor) to absorb the thin cover conveyed from the previous process, and make the thin cover stand up during the rotation of the magnetic wheel 31 and then transfer it to the material guide channel 21. The thin cover retaining assembly includes a magnetic component 32 arranged at the end position of the material guide channel 21. The magnetic component 32 is specifically arranged at the bottom of the guide groove. Under the action of the magnetic component 32, the thin cover transferred to the material guide channel 21 can be kept in a vertical stacking state to avoid tipping problems.

[0076] See also Figure 2 and Figure 3 The longitudinal pushing mechanism 40 is arranged at the second position of the frame 10, and is used to receive the stacked thin covers pushed by the transverse pushing mechanism 20, and drive the stacked thin covers to move along the second direction of the frame 10. Specifically, the thin covers can be pushed from the second position of the frame 10 to the third position of the frame 10 for coating processing.

[0077] The longitudinal pushing mechanism 40 includes a thin cover clamping device 41 and a second driving mechanism 46. For the convenience of implementation, a connecting seat 47 is provided on the power output end of the second driving mechanism 46, and the thin cover clamping device 41 is arranged on the connecting seat 47, so that it can reciprocate in the second direction of the frame 10. The second driving mechanism 46 can be a motor or a cylinder.

[0078] See also Figure 4 The thin cover clamping device 41 includes a support plate 42 that can receive the stacked thin covers, a pressing plate 43 located above the support plate 42 and capable of opening and closing relative to the support plate 42, and a third driving mechanism 48 that drives the pressing plate 43 to open and close relative to the support plate 42. Preferably, the extension direction of the support plate 42 and the pressing plate 43 is consistent with the first direction of the frame 10, that is, the support plate 42 and the pressing plate 43 can be a bent plate or an arc plate with openings facing each other (the support plate opening faces upward and the pressing plate opening faces downward). When the support plate 42 is closed relative to the support plate 42, a thin cover clamping channel 45 is formed between the pressing plate 43 and the support plate 42 for the stacked thin covers to enter and remain in an upright state, and the thin cover clamping channel 45 is connected to the port of the material guide channel 21.

[0079] Combination Figure 5 The inner wall surface of the pressing plate 43 is provided with a brush 44 for pressing the stacked thin covers. The arrangement of the brush 44, on the one hand, enables the stacked thin covers conveyed to the thin cover clamping channel through the material guide channel 21 to remain in an upright state, and on the other hand, also enables the reserved gap between the pressing plate 43 and the supporting plate 42 (in the closed state) to be relatively large (slightly larger than the outer diameter of the thin cover), so as to avoid interference with the process of the thin cover entering the thin cover clamping channel or the forward movement of the push plate 241.

[0080] See also Figure 4-Figure 6 In order to realize the opening and closing action between the pressing plate 43 and the supporting plate 42, the pressing plate 43 of the thin cover clamping device 41 is rotatably connected to the connecting seat 47, and the connecting seat 47 is provided with the above-mentioned third driving mechanism 48. The power output end of the third driving mechanism 48 is connected to the pressing plate 43, and can drive the pressing plate 43 to rotate relative to the connecting seat 47, thereby realizing the opening and closing action with the supporting plate 42.

Among them, the films on the above two film placing components are arranged vertically in the film area where the bonding position is located, and are correspondingly located in the forward path of the longitudinal pushing mechanism 40. As a result, the film on the film conveying mechanism 50 can be pressed by the longitudinal pushing mechanism 40 during the forward movement of the longitudinal pushing mechanism 40 to release the film 100 required for packaging (film placing is performed in conjunction with the driving mechanism).

Specifically, the first film tensioning roller assembly 52 includes two first brackets 71, a first tensioning roller 72, and a first proximity switch 73. The two first brackets 71 are vertically arranged and spaced apart in the first direction of the frame 10, and the two opposite surfaces of the two first brackets 71 are provided with vertically arranged first slide grooves 710. The two ends of the first tensioning roller 72 can be slid up and down in the first slide grooves 710 on the two first brackets 71 accordingly. The first tensioning roller 72 tensions the film laid on the first film tensioning roller assembly 52 under the action of its own gravity. The first proximity switch 73 is arranged on the first bracket 71, and is used to identify when the first tensioning roller 72 moves up to the set position, and outputs a signal to start the sixth drive mechanism 53 to the control system to release the film wrapped on the first film fixing roll 51.

[0084] In order to make the up and down movement of the first tensioning roller 72 more stable, gears 77 are coaxially installed at both ends of the first tensioning roller 72, and a vertically arranged rack 78 is provided on the side wall of the first slide groove 710 of the first bracket 71.

The second film unwinding assembly includes a second film fixing roll 54 for winding the film, a second film tensioning roller assembly 55 for laying the film, and a seventh driving mechanism 56 for driving the second film fixing roll 54 to rotate around its own axis to release the film.

[0086] See also Figure 7 , the second film tensioning roller assembly 55 also includes a plurality of fixed rollers fixed on the frame 10, so that the film is laid into an S-shaped or M-shaped structure. In addition to the above-mentioned fixed rollers, the second film tensioning roller assembly 55 also includes a tensioning roller that can be adjusted by its own weight. Specifically, the second film tensioning roller assembly 55 includes two second brackets 74, a second tensioning roller 75 and a second proximity switch 76. The two second brackets 74 are vertically arranged and spaced in the first direction of the frame 10. The two second brackets 74 are provided with vertically arranged second slide grooves 740 on the two opposite surfaces. The two ends of the second tensioning roller 75 can be correspondingly slid up and down in the second slide grooves 740 on the two second brackets 74. The second tensioning roller 75 tensions the film laid on the second film tensioning roller assembly 55 under the action of its own gravity. The second proximity switch 76 is arranged on the second bracket 74, which is used to identify when the second tensioning roller 75 moves up to the set position, and outputs a signal to start the seventh driving mechanism 56 to the control system to release the film wound on the second film fixed roll 54.

[0087] Similarly, gears 77 are coaxially mounted at both ends of the second tensioning roller 75 , and a vertically arranged rack 78 is provided on the side wall of the second slide groove 740 of the second bracket 74 . The gear 77 on the second tensioning roller 75 meshes with the rack 78 in the second slide groove 740 .

[0088] During the forward movement of the longitudinal pushing mechanism 40, the film laid on the film conveying mechanism 50 is pressurized by the longitudinal pushing mechanism 40, which can drive the first tensioning roller 72 of the first film tensioning roller assembly 52 and the second tensioning roller 75 of the second film tensioning roller assembly 55 to slide upward along the corresponding first slide groove 710 and the second slide groove 740. When moving to the set position, the corresponding proximity switch can identify this and output a signal to start the seventh drive mechanism 56 (and the sixth drive mechanism 53) to the control system to release the film required for wrapping. After the thermal cutting mechanism 80 cuts off the excess film after wrapping, the first tensioning roller 72 and the second tensioning roller 75 can move downward again under the action of their own gravity. At this time, the corresponding proximity switch outputs a signal to close the seventh drive mechanism 56 (and the sixth drive mechanism 53) to the control system to stop supplying film, thereby achieving the purpose of accurate film supply by the film conveying mechanism 50.

[0089] The sixth driving mechanism 53 of the first film placing assembly and the seventh driving mechanism 56 of the second film placing assembly can both adopt driving motors.

The rotating roller assembly of this embodiment can adopt a sprocket structure in the prior art that can realize both the cyclic rotation of the rotating roller assembly and the rotation of the rotating roller 900 around its own axis, such as adopting a structure similar to that of a roller conveying assembly in an automatic film packaging machine disclosed in the Chinese invention patent with application number CN201510276308.3 (authorization announcement number CN104859885B).

[0093] After the thin cover clamping device 41 of the longitudinal pushing mechanism 40 pushes the stacked thin covers to the third position of the frame, the pressure plate of the thin cover clamping device 41 opens, and the stacked thin covers clamped by it can be released to a positioning position of the roller conveying mechanism 90, that is, it is received by the two rotating rollers of the roller conveying mechanism 90, and then the thin cover clamping device 41 returns to the initial position. The thermal cutting mechanism 80 is activated to wrap the film around the outer periphery of the stacked thin covers, and after cutting off the excess film wrapped outside the stacked thin covers, a thin cover roller 102 initially wrapped with a film is formed, and the thin cover roller 102 can continue to move forward along the second direction of the frame under the drive of the roller conveying mechanism 90.

Among them, when the two ports of the thin cover roller are heated by the two hot air injection heads 93, the roller conveying mechanism 90 can control (through the cooperation of the proximity switch) the rotating roller 900 to rotate around its own axis, thereby driving the thin cover roller to rotate around its own axis at the stop position, thereby effectively improving the shaping effect and speed.

[0096] join Figure 12-14 The peripheral shaping device includes a hot air injection rack 95 located above the roller conveying mechanism 90 and extending along the first direction of the frame 10. The hot air injection rack 95 has a strip-shaped air outlet 950 that is consistent with the length direction of the hot air injection rack 95. The strip-shaped air outlet 950 is arranged downward and can spray hot air to the thin cover roller placed at the positioning position during the rotation around its own axis. The two hot air injection heads 93 and the hot air injection rack 95 share a stand 92. Specifically, when the periphery of the thin cover roller is heated by the above-mentioned hot air injection rack 95, the roller conveying mechanism 90 can also control (through the cooperation of the proximity switch) the rotating roller 900 to rotate around its own axis, thereby driving the thin cover roller to rotate around its own axis at the stop position, thereby improving the shaping effect and speed.

[0097] The heating and shaping process of the two hot air injection heads 93 and the hot air injection rack 95 can be carried out simultaneously at the same positioning position, or can be carried out successively at two positions in the moving direction of the rotating roller assembly, such as Fig.14 As shown, in order to make a reasonable spatial arrangement of the two hot air injection heads 93 and the hot air injection rack 95, the present embodiment first performs heat and shaping treatment on the two ports of the film on the periphery of the thin cover roller through the two hot air injection heads 93 at the previous position, and then, moves to the next position with the rotating roller assembly, performs heat and shaping treatment on the film on the periphery of the thin cover roller through the hot air injection rack 95.
