When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0034] The first embodiment of the utility model is as follows Figure 1-12 As shown: a chopstick film covering machine, including a workbench 40, on which a turntable seat 100, a film pulling mechanism 200 and a film feeding mechanism 300 are arranged in sequence, a color mark sensor 41 is arranged between the film pulling mechanism 200 and the film feeding mechanism 300, a cutting assembly 400 for cutting the cover film is arranged on the side of the film feeding mechanism 300 away from the film pulling mechanism 200, a chopstick feeding mechanism 500 is arranged on one side of the workbench 40, the chopstick feeding mechanism 500 is located downstream of the film feeding mechanism 300, a chopstick covering mechanism 700 for combining the cover film and chopsticks is arranged between the film feeding mechanism 300 and the chopstick feeding mechanism 500, an optical fiber sensor 42 for sensing chopsticks is arranged on the chopstick feeding mechanism 500, and a control module 600 for controlling the operation of each component is also arranged on the workbench 40.

[0035] The turntable seat 100, the film pulling mechanism 200, the film feeding mechanism 300, the cutting assembly 400, the chopstick sleeve mechanism 700 and the chopstick feeding mechanism 500 are sequentially arranged, and the operation of each assembly is controlled by the control module 600, wherein the turntable seat 100 is used to place the film sleeve strip, which is in the shape of a sleeve, and a plurality of transparent color marks are arranged on the film sleeve strip, and the film sleeve is divided into individual film sleeve pieces by the color marks thereon, and one end of the film sleeve strip is wound around the turntable seat 100, and the other end extends out and first passes through the gap between the driving shaft 2002 and the rubber wheel 2004 in the film pulling mechanism 200 to pull it, and then is transported to the bottom of the color mark sensor 41 by the cooperation of the outer clamping wheel 2005 on one side and the film 2006, and the color mark between the adjacent film sleeve pieces is sensed by the color mark sensor 41, and then the film sleeve strip is supported by the support on the film feeding center rod 7. The opening portion enters into the film feeding mechanism 300, and the film strip is fed to the cutting assembly 400 by the film feeding mechanism 300. At this time, the chopstick feeding mechanism 500 also synchronously feeds the chopsticks thereon to a position flush with the film piece. When the optical fiber sensor 42 thereon senses the chopsticks, it transmits it to the control module 600, and then the control module 600 controls the cutting assembly 400 to cut the color mark on the film strip. The cut film piece is fed to the chopsticks by the chopstick sleeve mechanism 700, thereby completing the assembly of the chopsticks and the film piece. The assembled chopsticks are then pressed into shape by a heat shrink mechanism. Through the above structure, the film and chopsticks are quickly assembled and formed in an automated manner, thereby solving the technical problem of high cost and low efficiency of the existing manual film method. At the same time, the device can also be used for a set of a pair of chopsticks to increase the packaging efficiency of chopsticks.

[0036] like Figure 1 As shown: a vertical frame is provided on the workbench 40, and the vertical frame is located below the side of the outer pressure wheel 2005 away from the film pulling mechanism 200. A color mark frame 410 is detachably provided on the vertical frame. The color mark sensor 41 is fixed on the color mark frame 410, and the induction electrode thereon is set downward. A film sleeve channel is provided below the color mark frame 410. The film sleeve strip is aligned with the film sleeve channel through the leveling of the film feeding mechanism 300. A pressure wheel is also provided at the output end of the film sleeve channel so that it can accurately enter under the color mark sensor 41. The detachable setting of the color mark frame 410 can make it more convenient to adjust the color mark sensor 41, so that the cutting position of the film sleeve strip can be determined according to the position of the color mark sensor 41. When in use, the color mark sensor 41, the optical fiber sensor 42 and the cutting assembly 400 are all synchronously operated by the control module 600. The control module 600 is an integrated control machine, on which the operating parameters of each component can be set.

Figure 1 As shown: the machine base 1 is formed by four side blocks and a bottom surface, and a accommodating cavity is formed in between. The film feeding motor 2 is installed on the left block and the output end thereof is located in the accommodating cavity. The fixed plate is welded by side plates 3 and bottom plates 4 that are perpendicular to each other. Four film feeding wheel shafts 5 are provided on the side plates 3 and the bottom plate 4. The side film feeding wheel shaft 501 on the side plate 3 is connected to the output end of the film feeding motor 2 through the side film feeding wheel shaft driving mechanism. The side film feeding wheel shaft driving mechanism is located between the left block and the side plate 3. The lower film feeding wheel shaft 502 on the bottom plate 4 is linked to each other through the lower film feeding wheel shaft driving mechanism. The lower film feeding wheel shaft driving mechanism is located in the accommodating cavity, wherein the lower film feeding wheel shaft driving mechanism is connected to the side film feeding wheel shaft driving mechanism through the eccentric driving mechanism. In this way, only one driving motor is needed to complete the synchronous rotation of the film feeding wheel shaft 5 on the side plate 3 and the bottom plate 4, thereby reducing costs and improving overall work efficiency.

[0038] like Figure 2-6 As shown: the film feeding center rod 7 is detachably placed horizontally between the fixed plates, one end of which is the material supporting part 701, and the middle end is the first film feeding part 702. The first film feeding part 702 is located between the fixed plate and the film feeding wheel axle 5. The end of the first film feeding part 702 away from the material supporting part 701 extends out of the machine base 1 through the feeding channel, and the section extending out of the machine base 1 is the second film feeding part 705.

[0039] like Figure 7-9 As shown: the cutting assembly 400 includes an electric slip ring 20 and a rotating transmission mechanism, the electric slip ring 20 is arranged in the feeding channel, the fixed end of the electric slip ring 20 is arranged on the machine base 1, the movable end of the electric slip ring 20 is provided with a rotating transmission mechanism, the rotating transmission mechanism is provided with a cutter assembly, one end of the film feeding center rod 7 passes through the electric slip ring 20 and the rotating transmission mechanism, the cutting part of the cutter assembly is arranged around the film feeding center rod 7, the electric slip ring 20 and the cutting transmission disk 31 are provided with openings for placing the film feeding center rod 7, the opening of the cutting transmission disk 31 is provided with a bearing, and the film material on the film feeding center rod 7 is conveniently transported to the cutting assembly through the opening and the bearing.

[0040] By providing an electric slip ring 20 in the feeding channel, and arranging a cutting transmission disk 31 on the movable end of the electric slip ring 20, a cutter assembly is provided on the cutting transmission disk 31, and the cutter assembly can rotate accordingly with the rotation of the cutting transmission disk 31. When in use, the film material is conveyed out from the opening in the middle of the cutting transmission disk 31 through the film conveying center rod 7 via the electric slip ring 20 in the feeding channel. Since the cutter assembly is arranged around the film conveying center rod 7, the conveyed film material is located below the cutter head 222 of the cutter assembly. When the cutting transmission disk 31 is driven to rotate by the cutter motor 30, it will simultaneously drive the cutter motor 30 and the cutter motor 30. The electric slip ring 20 rotates, thereby triggering the pushing electromagnet 21 electrically connected to the electric slip ring 20. The pushing electromagnet 21 pushes the cutter head 222 thereon downward to make the cutter head 222 fully contact with the film material. At the same time, since the cutter assembly is in a high-speed rotating state, and the film material sleeved on the film feeding center rod 7 is in a static state, the high-speed rotating cutter head 222 completes 360° all-round cutting around the film material on the film feeding center rod 7. Through the above structure, only one cutter head is needed to complete the all-round cutting of the film material, and the structure is simpler, so as to solve the technical problems of high cost and complex structure of the existing cutting device.

[0042] The cutter motor 30 is arranged on the inner side of the machine base 1, and its output end extends out of the machine base 1 through an opening on the machine base 1.

[0045] like Fig. 9 As shown: the cutter head 222 is tilted relative to the film feeding center rod 7. When powered on, the blade of the cutter head 222 contacts the film feeding center rod 7. This method enables the blade of the cutter head 222 to fully contact the film feeding center rod 7, making cutting easier.

[0047] like Figure 7 As shown: a slip ring mounting part 25 is provided on one side of the base 1 close to the feeding channel, and the fixed end of the electric slip ring 20 is fixed to the slip ring mounting part 25 by threaded connection. The slip ring mounting part 25 is located inside the base 1, and is provided with an opening for the film feeding center rod 7 to pass through.

[0048] The cutting drive disc 31 rotates at a constant speed, which makes the cutting more uniform.

[0049] The implementation method is as follows:

[0050] During use, the film material is transported to the cutting assembly 400 by the film feeding mechanism 300, and the chopstick feeding mechanism 500 on the other side will synchronously transport the chopsticks to the same level as the film material. An optical fiber sensor 42 is provided above the chopstick feeding mechanism 50, and when it senses the chopsticks, it will transmit the information to the control module 600. After receiving the information from the optical fiber sensor 42, the control module 600 will start the cutter motor 30 and drive the electric slip ring 20, so that the electric slip ring 20 triggers the pushing electromagnet 21, presses down the cutter head located at the pushing end of the pushing electromagnet 21 and rotates at high speed around the film feeding center rod 7 to cut the film material. The cut film material will be assembled with the chopsticks by the turntable to complete the whole process.

Every two guide wheels 8 are in contact with a film feeding wheel 6 on a film feeding wheel shaft 5 to form a feeding point. When the film feeding wheel shaft 5 drives the film feeding wheel 6 to rotate, since it is between the two guide wheels 8, it will rub against the two guide wheels 8 to rotate the two guide wheels 8. Through this design method, the film feeding is avoided. The core rod 7 will be driven by the film feeding wheel 6 on the film feeding wheel shaft 5 so that the film feeding center rod will rush forward. At the same time, one end of the film feeding center rod 7 passes through the feeding channel on the machine base 1 and is connected to the downstream of the film feeding mechanism and the cutting assembly and the chopstick feeding assembly. When in use, the film sleeve will first be covered on the first film feeding part of the film feeding center rod by the supporting part of the film feeding center rod, and then the film sleeve wrapped on the film feeding center rod will be driven forward by the cooperation of the film feeding wheel shaft and the guide wheel on the first film feeding part, and then enter the cutting assembly through the feeding channel to complete the cutting, and then the external feeding assembly will cooperate with the guide wheel on the second film feeding part to send it to the chopstick feeding assembly to complete the film sleeve of the chopsticks.
