Description

Technical Field

[0001] The utility model relates to the technical field of tea filling equipment, in particular to a cap buckling and film placing device for tea capsule assembly. Background Art

[0002] Capsule drinks are very popular because of their hygiene and convenience, and can quickly obtain a drink with excellent taste when combined with a brewing machine. Existing capsules mainly consist of a capsule cup, a shower head cover, a film and contents (such as tea, coffee). After the contents are filled into the main body of the cup, the shower head cover is generally placed on the step of the inner edge of the capsule cup, and the film is generally heat-sealed and welded to the edge end face of the capsule cup. Among them, the film is generally manually placed on the edge of the capsule cup for welding, with low production efficiency and easy deviation when manually controlled. Another method is to directly cut the roll film into sheet films online and then weld them. Although the degree of automation is high, the edges of the sheet films after online cutting are easy to be serrated, which damages the appearance quality of the film.

[0060] As Figures 1 to 19 shown, the present utility model provides a cap - buckling and film - placing device for tea capsule assembly, including a production line conveyor belt 4; the production line conveyor belt 4 is mounted on a frame 8;

[0061] Along the conveying direction of the production line conveyor belt 4, a cap - buckling part 1 for buckling a flower - sprinkling cap 6 onto a capsule cup 5, a film - placing part 2 for placing a film 7 on the rim of the capsule cup 5 after cap - buckling, and a heat - sealing part 3 for heat - sealing the film 7 onto the rim of the capsule cup 5 are sequentially arranged.

[0062] The film - placing part 2 includes a film - storing structure 21 and a film - sucking structure 22. The film - storing structure 21 stores the film 7 in the form of a sheet film. The film - sucking structure 22 includes a film - sucking disc 221 that can be lifted and rotated. The film - sucking disc 221 sucks and places the film through the opening and closing of vacuum suction; the film - sucking disc 221 can suck the film 7 in the film - storing structure 21 and place the film 7 on the rim of the capsule cup 5.

[0063] The cap - buckling and film - placing device for tea capsule assembly of the present utility model solves the problems of film deviation in the existing manual method and the problem of poor serrated edges of the film in the online punching method of roll film; by the method that the film - sucking disc 221 moves and rotates to a predetermined position in the film - storing structure 21 to suck the film 7 in the form of a sheet film, and then rotates and moves back in the reverse direction to the film - placing position to place the film, the automatic sucking and placing of the film at a predetermined position are realized; the film - sucking disc 221 realizes the sucking and placing of the film through the opening and closing of vacuum suction; the predetermined path of the rotation and movement of the film - sucking disc 221 defines the fixed position of the film sucking and placing, thereby solving the problem of film deviation; the present utility model uses the film 7 in the form of a sheet film to replace the online punching method of roll film, improving the appearance quality of the film; the present utility model improves the degree of automation, improves production efficiency, is simple and easy to implement, has a low manufacturing cost, and can be widely used in various production lines for capsule filling.

[0064] Further, as Figure 2 、 Figure 5 shown, the film - placing part 2 further includes a cylinder structure 23 for driving the lifting of the film - sucking disc 221.

[0065] Further, as Figure 5As shown, the film suction structure 22 further includes a rotating body 223, a rotating shaft 222, and a suction valve 224. An air suction channel is provided inside the rotating shaft 222. The first end of the air suction channel is open, and the second end is closed. The film covering suction cup 221 is arranged near the second end of the air suction channel and is communicated with it. That is, the rotating shaft 222 is a hollow structure with one end open and one end closed. The film covering suction cup 221 is fixedly connected near the closed end of the rotating shaft 222, and the rotating body 223 is fixedly connected near the open end of the rotating shaft 222.

[0066] The suction valve 224 is communicated and arranged at the first end (i.e., the open end) of the air suction channel; the rotating body 223 is fixedly sleeved on one end of the rotating shaft 222 away from the film covering suction cup 221; specifically, the rotating body 223 is fixedly connected to the rotating shaft 222 through a rotating body snap ring 225.

[0067] The rotating shaft 222 is rotationally connected to a cylinder structure 23. The cylinder structure 23 drives the rotating shaft 222 to move up and down to drive the film covering suction cup 221 and the rotating body 223 to move up and down. The rotating body 223 can drive the rotating shaft 222 to rotate during the up and down movement so that the opening of the film covering suction cup 221 rotates to the film covering storage structure 21.

[0068] The suction valve 224, the rotating shaft 222, and the film covering suction cup 221 are internally communicated. The suction valve 224 sucks air through the air suction channel (the hollow structure of the rotating shaft), and then generates suction force on the film covering suction cup 221, so as to suck the film covering 7 inside it when the film covering suction cup 221 reaches the film covering storage structure 21 (see the movement state drawing details in Figure 17 ).

[0069] The suction valve 224 stops sucking air when the film covering suction cup 221 returns from the film covering storage structure 21 to the production line conveyor belt 4 (initial state). The film covering 7 detaches from the film covering suction cup 221 and falls on the cup mouth edge surface of the capsule cup 5 to complete the placement of the film covering.

[0070] By driving the film covering suction cup 221 (pneumatic suction cup) to rotate to a predetermined position to suck the film sheet and then rotate in the reverse direction back to the starting position to place the film covering, the suction and placement of the film covering at the predetermined position are realized. The opening and closing of the vacuum suction of the film covering suction cup 221 solve the problem of sucking and placing the film covering. The predetermined path of the rotation of the film covering suction cup 221 defines the fixed position of sucking and placing the film covering, thus solving the problem of film deviation.

[0071] Furthermore, as shown in Figure 5 , Figure 6As shown in the figure, the film placing part 2 further includes a vertically arranged rotating back plate 226. A rotating shaft limiting chute 2261 is arranged on the rotating back plate 226. A rotating shaft slideway 227 is arranged on one side of the rotating back plate 226. A slider 228 capable of sliding along it is sleeved on the rotating shaft slideway 227. The rotating shaft 222 rotates through the slider 228 and the rotating shaft limiting chute 2261, and the slider 228 is connected to the cylinder structure 23. A rotating column 229 is also arranged on the rotating back plate 226. During the lifting process, the rotating body 223 rotates circumferentially along the rotating column 229 to drive the rotating shaft 222 and the film covering suction cup 221 to rotate.

[0072] Further, as Figure 5 shown in the figure, a bearing seat 220 is connected to the slider 228. Bearings 2201 are arranged at both ends of the bearing seat 220. The rotating shaft 222 rotates through the bearings to be rotatably connected to the slider 228.

[0073] Near the middle section of the outside of the rotating shaft 222, two bearings are sleeved through the bearing seat 220, so that the rotating shaft 222 can rotate within the bearings. When the rotating shaft 222 rotates within the bearings, it synchronously drives the rotating body 223 and the film covering suction cup 221 fixedly connected to the rotating shaft 222 to rotate. The bearing seat 220 is fixedly connected to the slider 228 via a slider connecting plate 2281. The slider 228 can slide up and down on the rotating shaft slideway 227, thereby driving the entire film suction structure 22 to move up and down within the rotating shaft limiting chute 2261.

[0074] Further, as Figure 5 shown in the figure, the cylinder structure 23 includes a cylinder 231. A pneumatic push rod 232 is slidably inserted into the cylinder 231. A cylinder blowing valve 233 and a cylinder suction valve 234 are respectively arranged at both ends of the cylinder 231. A push block extension rod 235 is connected to the pneumatic push rod 232, and the push block extension rod 235 is connected to the bearing seat 220.

[0075] The cylinder structure 23 controls the up and down movement of the film suction structure 22. The pneumatic push rod 232 is fixedly connected to the push block extension rod 235, and the push block extension rod 235 is vertically and fixedly connected to the bearing seat 220 of the film suction structure 22. The pneumatic push rod 232 can move back and forth within the cylinder 231. When the cylinder blowing valve 233 blows air, the pneumatic push rod 232 rises under the air force and pushes the film suction structure 22 up via the push block extension rod 235. When the cylinder suction valve 234 sucks air, the pneumatic push rod 232 drops under the air force and pulls the film suction structure 22 back to the initial state via the push block extension rod 235.

[0076] Further, as Figure 6 、 Figure 7 shown in the figure, the rotating body 223 includes a semi-circular body. A first groove 2231 is arranged inward at the center of the chord side of the semi-circular body. Symmetrical arc tracks 2232 are arranged inward from the chord side on the semi-circular body. A second groove 2233 is arranged inward at a position opposite to the first groove 2231 on the arc side of the semi-circular body.

[0077] At both ends of the rotating shaft limiting chute 2261, a rotating column 229 is respectively arranged, and the second groove 2233 can be stuck at the rotating columns 229 at both ends of the rotating shaft limiting chute 2261 to limit the rotating body; at least one rotating column 229 is arranged on one side of the rotating shaft limiting chute 2261, and the arc track or the first groove can rotate along the rotating column 229 on one side of the rotating shaft limiting chute 2261 to guide the rotation of the rotating body 223.

[0078] When the entire film sucking structure 22 moves up and down, it drives the rotating body 223 to rotate circumferentially along the rotating column 229 on the rotating back plate 226, thereby driving the entire film sucking structure 22 to rotate circumferentially, and further enabling the cover film suction cup 221 to move from the production line conveyor belt 4 (initial state) to the cover film storage structure 21 (for the movement state drawing details, see Figure 17 ) for reciprocating rotation.

[0079] In a specific embodiment of the present utility model, there are a total of 5 rotating columns 229, which are distributed from low to high; there is 1 at each of the top and bottom ends of the rotating shaft limiting chute 2261, and 3 are arranged on one side of the rotating shaft limiting chute 2261; the rotating columns 229 at the topmost and bottommost ends play a role in limiting the upper and lower limits of the rotating body 223. Thus, the state of the cover film suction cup 221 can be divided into an initial state, a movement state 1, a movement state 2, a movement state 3, and a movement state 4. The initial state refers to the state where the opening of the cover film suction cup 221 faces downward corresponding to the capsule cup 5 on the production line conveyor belt 4 (see Figure 13 ); at this time, the second groove 2233 is stuck at the rotating column 229 at the bottom end of the rotating shaft limiting chute 2261 (the state of the rotating body 223 is as shown in Figure 8 ); the movement state 1 is the state when an arc track of the rotating body 223 rotates around the lowest rotating column 229 on one side of the rotating shaft limiting chute 2261 (the states of the rotating body 223 and the cover film suction cup 221 are respectively as shown in Figure 9 , Figure 14 ); the movement state 2 is the state when the two arc tracks and the first groove 2231 of the rotating body 223 are respectively sleeved on the 3 rotating columns 229 on one side of the rotating shaft limiting chute 2261 (the states of the rotating body 223 and the cover film suction cup 221 are respectively as shown in Figure 10 , Figure 15 ); the movement state 3 is the state when an arc track of the rotating body 223 rotates away from the lowest rotating column 229 on one side of the rotating shaft limiting chute 2261 (the states of the rotating body 223 and the cover film suction cup 221 are respectively as shown in Figure 11 , Figure 16 ); the movement state 4 is the state when the rotating body 223 rises and rotates 180°, and the opening of the cover film suction cup 221 faces upward corresponding to the cover film storage structure 21 (as shown in Figure 17 ), at this time, the second groove 2233 is stuck at the rotating column 229 at the top end of the rotating shaft limiting chute 2261 (the state of the rotating body 223 is as shown inFigure 12 as shown

[0080] When the cylinder structure 23 gradually pushes the film suction structure 22 upward, the rotating body 223 is synchronously pushed upward. The arc track of the rotating body 223 guides the upward movement direction of the rotating body 223. Therefore, the movement track of the rotating body 223 is to climb while rotating along each rotating column 229, and synchronously drives the rotating shaft 222 connected to it to rotate and climb. The cover film suction cup 221 connected to the closed end of the rotating shaft 222 rotates and climbs synchronously with the rotating body 223.

[0081] When the rotating body 223 rotates and climbs from the initial state (see Figure 8 ) to the motion state 4 (see Figure 12 ), the cover film suction cup 221 also rotates and climbs to the motion state 4 accordingly. At this time, the rotating body 223 is restricted by the topmost rotating column 229 and no longer rises after moving to the motion state 4. The rotating body 223 rotates 180° compared with the initial state. The cover film suction cup 221 also synchronously reaches the established highest point and rotates 180° relative to the initial state. At this time, the opening of the cover film suction cup 221 faces and is close to the cover film storage structure 21. At this time, the suction valve 224 connected to the open end of the rotating shaft sucks air, and sucks out the cover film 7 stacked in the cover film storage structure 21 (inside the cover film storage cylinder 211) from the bottom opening. The continuous suction force of the suction valve 224 causes the cover film 7 to be sucked on the cover film suction cup 221 and not to fall off.

[0082] After the cover film suction cup 221 sucks the cover film 7, the cylinder air blowing valve 233 stops working, and the cylinder suction valve 234 starts working. The pneumatic push rod 232 of the cylinder structure 23 moves downward, synchronously pulling the rotating body 223 downward. Under the guiding and limiting action of each rotating column 229, the rotating body 223 gradually moves back to the initial state from the motion state 4 through the motion state 3, the motion state 2, and the motion state 1. Due to the limiting action of the lowermost rotating column 229, the rotating body 223 stops descending when it moves to the established lowest point. During this process, the cover film suction cup 221 gradually rotates and falls back to the initial state synchronously. At this time, the opening of the cover film suction cup 221 faces the capsule cup mouth on the production line conveyor belt. At this time, the suction valve 224 connected to the open end of the rotating shaft stops sucking air, and the cover film 7 detaches from the cover film suction cup 221 and falls on the capsule cup mouth edge surface to complete the placement of the cover film.

[0083] Furthermore, as Figure 5 shown, the cover film storage structure 21 includes a cover film storage cylinder 211 and a cover film baffle 212. Multiple cover films 7 are stacked in the cover film storage cylinder 211; the cover film storage cylinder 211 is vertically arranged and has openings at both ends. In a specific embodiment, the cover film storage cylinder 211 is a straight cylinder structure with a hollow interior and through holes at both ends. The internal space shape of this straight cylinder structure matches the shape and size of the cover film. A support plate is provided at the top of the rotating back plate 226, and the cover film storage cylinder 211 is supported on the support plate.

[0084] The film covering baffle 212 is arranged at the bottom opening of the film covering storage cylinder 211 to prevent the film covering 7 from falling; the film covering suction cup 221 rises and its opening rotates to the bottom of the film covering storage cylinder 211, and then sucks the film covering 7 in the film covering storage cylinder.

[0085] Furthermore, as Figure 3 、 Figure 4 shown, the cover buckling part 1 includes a first shower head cover suction cup 11, a second shower head cover suction cup 12 and a shower head cover turntable 13. The first shower head cover suction cup 11 and the second shower head cover suction cup 12 move up and down and horizontally synchronously; the second shower head cover suction cup 12 adsorbs and transfers the shower head cover 6 outside the production line conveyor belt 4 to the shower head cover turntable 13, and the shower head cover turntable 13 rotates the shower head cover 6 thereon by a set angle to match the placement direction of the capsule cup 5 on the production line conveyor belt 4; the first shower head cover suction cup 11 adsorbs and transfers the shower head cover 6 after being rotated by the shower head cover turntable 13 and buckles it on the capsule cup 5 on the production line conveyor belt 4.

[0086] Furthermore, as Figure 4 shown, the first shower head cover suction cup 11 and the second shower head cover suction cup 12 are respectively connected to both sides of the first lifting rod 14. The first lifting rod 14 is connected to the lifting rod connection block 15, and the lifting rod connection block 15 can move horizontally and perpendicular to the production line conveyor belt 4.

[0087] Furthermore, as Figure 4 shown, a connection block slideway 16 is fixedly arranged on one side of the lifting rod connection block 15. A first horizontal push-pull rod 171 is connected to the lifting rod connection block 15, and the first horizontal push-pull rod 171 pushes the lifting rod connection block 15 to move horizontally along the connection block slideway 16.

[0088] Furthermore, as Figure 3 、 Figure 4 shown, the cover buckling part 1 includes a shower head cover sorting tray 18. A shower head cover conveyor belt 181 is arranged below the shower head cover sorting tray 18. One end of the shower head cover conveyor belt 181 is provided with a push-pull connection block 19 for receiving the shower head cover 6. The push-pull connection block 19 can move horizontally to move the shower head cover to the shower head cover suction position, and the second shower head cover suction cup 12 sucks the shower head cover 6 at the shower head cover suction position.

[0089] Furthermore, as Figure 4 shown, a second horizontal push-pull rod 172 is connected to the push-pull connection block 19, and the second horizontal push-pull rod 172 pushes the push-pull connection block 19 to move horizontally.

[0090] After the capsule cup 5 is filled with the content, it enters the process of buckling the shower head cover. The shower head cover 6 is placed on the step at the edge of the capsule cup mouth. Its functions are: on the one hand, it can enhance the strength of the whole capsule; on the other hand, the buckling of the shower head cover can compress the content in the cup (such as tea raw materials, which are fluffy and easy to protrude from the cup edge) to a certain extent, preventing the content from protruding from the capsule cup mouth edge after filling and affecting the subsequent process of welding the cover film.

[0091] The shower head cover sorting tray 18 sends the shower head cover 6 to the shower head cover conveyor belt 181 through vibratory sorting, and the shower head cover conveyor belt 181 sends the shower head cover 6 to the push-pull connection block 19 connected to the second horizontal push rod 172. At this time, the second horizontal push rod 172 pushes the push-pull connection block 19 together with the shower head cover 6 in the direction of the first horizontal push rod 171 under the action of pneumatic force and stops at the shower head cover suction position.

[0092] At the same time, the lifting rod connection block 15 of the first lifting rod 14 moves along the connection block slideway 16 in the pulling force of the first horizontal push rod 171 in the direction away from the production line conveyor belt 4 until the second shower head cover suction cup 12 is exactly above the shower head cover suction position.

[0093] At this time, the first shower head cover suction cup 11 and the second shower head cover suction cup 12 drive by the first lifting rod 14 move downward from the starting height until the second shower head cover suction cup 12 touches the shower head cover 6 at the shower head cover suction position. Synchronously, the first shower head cover suction cup 11 touches the shower head cover 6 that has rotated a certain angle in the shower head cover turntable 13.

[0094] The first shower head cover suction cup 11 and the second shower head cover suction cup 12 respectively suck the shower head cover 6 in the shower head cover turntable 13 and at the shower head cover suction position under the action of pneumatic suction.

[0095] The shower head cover turntable 13 is a transfer position for the transportation of the shower head cover. The functions of this transfer position are: on the one hand, it reduces the problem of transportation position deviation caused by a long transportation distance in one step; on the other hand, it adjusts the placement position of the shower head cover at the transfer position so that it can be directly matched for buckling and installation above the capsule cup on the production line. The shower head cover 6 in the shower head cover turntable 13 is transported from the shower head cover suction position by the second shower head cover suction cup 12. The shower head cover turntable 13 has a rotating function. After the second shower head cover suction cup 12 transports the shower head cover to the shower head cover turntable 13, the shower head cover turntable 13 immediately starts to rotate by a certain angle so that the placement direction of the shower head cover 6 matches the placement direction of the capsule cup 5 on the production line conveyor belt 4 for matching buckling. After the shower head cover completes the rotation of the certain angle, the first shower head cover suction cup 11 descends to suck the shower head cover 6 in the shower head cover turntable 13. The rotation action of the shower head cover turntable 13 occurs before the first shower head cover suction cup 11 descends.

[0096] The first shower head cover suction cup 11 and the second shower head cover suction cup 12, together with the shower head covers 6 they respectively suck, rise to the starting height of the first lifting rod 14 driven by the first lifting rod 14. After the shower head cover turntable 13 and the shower head covers 6 at the shower head cover suction positions are respectively sucked by the first shower head cover suction cup 11 and the second shower head cover suction cup 12, the shower head cover turntable 13 and the shower head cover suction positions are in the state of an empty plate without shower head covers. At this time, the second horizontal push rod 172 pulls the push-pull connection block 19 backward to the starting position. Then, the shower head cover conveyor belt 181 conveys new shower head covers 6 to the push-pull connection block 19 again, so that the second horizontal push rod 172 can push the shower head covers to the shower head cover suction position next time.

[0097] The first horizontal push rod 171 pushes the first lifting rod 14 together with the first shower head cover suction cup 11 and the second shower head cover suction cup 12 that have sucked the shower head covers in the direction of the production line conveyor belt 4 through the lifting rod connection block 15 until the first shower head cover suction cup 11 is directly above the capsule cup 5 on the production line conveyor belt 4. At this time, the second shower head cover suction cup 12 is directly above the shower head cover turntable 13. Then, the first lifting rod 14 drives the first shower head cover suction cup 11 and the second shower head cover suction cup 12 to move downward until the shower head cover on the first shower head cover suction cup 11 touches the edge of the capsule cup 5 on the production line conveyor belt 4. At this time, the shower head cover on the second shower head cover suction cup 12 is inside the shower head cover turntable 13.

[0098] At this time, the suction of the first shower head cover suction cup 11 and the second shower head cover suction cup 12 is stopped, and the shower head covers are separated from the first shower head cover suction cup 11 and the second shower head cover suction cup 12. The shower head cover on the first shower head cover suction cup 11 is placed and installed on the edge of the capsule cup 5 on the production line conveyor belt 4, and the shower head cover on the second shower head cover suction cup 12 falls into the shower head cover turntable 13. A complete installation process of buckling the shower head cover is completed.

[0099] The first lifting rod 14 drives the first shower head cover suction cup 11 and the second shower head cover suction cup 12 that have separated from the shower head covers to move upward to the starting height, and then, under the pulling of the first horizontal push rod 171, the first shower head cover suction cup 11 and the second shower head cover suction cup 12 are respectively pulled back to directly above the shower head cover suction position and the shower head cover turntable 13. At this time, new shower head covers have been transported to the shower head cover suction position under the push of the second horizontal push rod 172, and new shower head trays have been transported to the inside of the shower head cover turntable 13 by the second shower head cover suction cup 12 in the previous buckling cover process. Then, the first lifting rod 14 drives the first shower head cover suction cup 11 and the second shower head cover suction cup 12 to move downward to contact the shower head covers at their respective corresponding positions for sucking and transporting, and start the next buckling cover process.

[0100] Further, as Figure 18 、 Figure 19 shown, the heat sealing part 3 includes a heat sealing head 31, and a second lifting rod 32 capable of driving its lifting is connected to the heat sealing head 31.

[0101] The hot sealing head 31 heated to a predetermined temperature moves downward under the drive of the second lifting rod 32 until it presses against the capsule cup 5 after the cover film 7 is placed. After maintaining the pressure for a predetermined time, the cover film 7 is welded to the edge of the capsule cup. At this time, the hot sealing head 31 moves upward (in the direction away from the production line conveyor belt) under the drive of the second lifting rod 32 to disengage from the capsule cup 5. The cover film hot sealing is completed.

[0102] After the capsule cup is filled with the content, it undergoes three processes to become a finished capsule: in sequence: buckling the shower head cover, placing the cover film, and hot sealing the cover film. Specifically, it includes:

[0103] After the capsule cup 5 is filled with the content, it enters the process of buckling the shower head cover. The shower head cover 6 is placed on the step at the edge of the capsule cup. This process is completed by the cover buckling part 1.

[0104] After the capsule cup 5 undergoes the process of buckling the shower head cover, the cover film 7 is placed. Placing the cover film 7 means accurately placing the cover film 7 for sealing on the edge surface of the capsule cup after the cover is buckled. This process is completed by the film placing part 2.

[0105] After the capsule cup 5 places the cover film, it enters the next working station, namely the cover film hot sealing station, under the drive of the production line conveyor belt 4, and the last cover film hot sealing process is carried out for welding and sealing. This process is completed by the hot sealing part 3.

[0106] As described above, the cover buckling and cover film placing device for assembling tea capsules of the present utility model has the following beneficial effects:

[0107] The present utility model solves the problems of film deviation in the existing manual method and the problem of poor serrated edges of the cover film in the online punching method of the rolled film; by the method of moving and rotating the cover film suction cup to the predetermined position of the cover film storage structure to suck the cover film in the form of a sheet film, and then rotating and moving back in the reverse direction to the cover film position to place the cover film, the automatic suction and placement of the cover film at the predetermined position are realized; the cover film suction cup realizes the suction and placement of the cover film through the opening and closing of vacuum suction; the predetermined path of the rotation and movement of the cover film suction cup limits the fixed position of the suction and placement of the cover film, thereby solving the problem of film deviation; the present utility model uses the cover film in the form of a sheet film to replace the online punching method of the rolled film, improving the appearance quality of the cover film; the present utility model improves the degree of automation, making the production efficiency increase, being simple and easy to implement, having a low manufacturing cost, and can be widely used in various production lines for capsule filling.

[0108] The above is only the schematic specific implementation manner of the present utility model, and is not used to limit the scope of the present utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present utility model shall fall within the scope of protection of the present utility model.
