[0028] The following are specific embodiments of the present utility model, in combination with the accompanying drawings, to further describe the technical solutions of the present utility model, but the present utility model is not limited to these embodiments.

[0029] As Figures 1 to 3 shown in combination with Figure 6 a continuous film waste trimming and material receiving device includes a machine table 10, a feeding roller 21, a material receiving roller 22, a front feeding table 31, a rear feeding table 32, a detection mechanism 40, a front auxiliary roller group 51, a cutting mechanism 60, a collection mechanism 70 and a material receiving mechanism 80. The feeding roller 21 and the material receiving roller 22 are respectively arranged at both ends of the machine table 10. The front feeding table 31 and the rear feeding table 32 are arranged flush on both sides of the machine table 10 for carrying the continuous film 1A, and an interval for installing the front auxiliary roller group 51, the cutting mechanism 60 and the collection mechanism 70 is formed between them. The detection mechanism 40 is arranged above the front feeding table 31, and it can use a CCD camera for visually detecting the defective area 1B' on the continuous film 1A. The whole film area with the defective area 1B' detected is positioned as the waste 1B. The front auxiliary roller group 51 is arranged at the rear side of the front feeding table 31 for driving the conveyance of the continuous film 1A. The collection mechanism 70 includes a lifting cylinder 71 and a cover plate 72. The lifting cylinder 71 is arranged on the machine table 10 and near the front side of the rear feeding table 32. The cover plate 72 is arranged at the output end of the lifting cylinder 71 and is flush with the rear feeding table 32, and after being driven to move upward, it opens the material receiving port 100 communicating with the machine table 10. The cutting mechanism 60 is arranged between the front auxiliary roller group 51 and the collection mechanism 70 for trimming the waste 1B into the material receiving port 100. The material receiving mechanism 80 is arranged above the rear feeding table 32, and it includes a moving module 82 and a tape sticking module 83. The tape sticking module 83 is arranged on the moving module 82 for connecting the film after the waste 1B is trimmed and continues to be fed with the previous section of the film through the tape, so as to form a continuous film and then continue to be fed and wound around the material receiving roller 22.

[0030] In the present utility model, a whole roll of continuous film material 1A is placed on a feeding roller 21 for feeding. The continuous film material 1A in an unfolded state sequentially passes through the upper end of a front feeding table 31, passes through a front auxiliary roller group 51 and is pulled forward for conveying, passes through a cutting mechanism 60, is located at the upper end of a cover plate 72, passes through the upper end of a rear feeding table 32, and is finally wound around a receiving roller 22. During the whole feeding process, a detection mechanism (CCD camera) visually detects a defective area 1B' on the continuous film material 1A. The entire material area with the defective area 1B' is waste material 1B. Then, at the front end position of the waste material 1B, the cutting mechanism 60 cuts along a first cutting line 1C (a virtual cutting line). The front formed material 1A' near the first cutting line 1C and the film material at its front end continue to be driven forward by the receiving roller 22, are located at the upper end of the rear feeding table 32, and stop moving forward when reaching below a tape sticking module 83. At the same time, since the continuous film material 1A has been cut, the film material behind the first cutting line 1C is pulled forward by the front auxiliary roller group 51, and a lifting air cylinder 71 drives the cover plate 72 to move upward to open a receiving opening 100. The waste material 1B is pushed into the receiving opening 100. When the end position of the waste material 1B is located below the cutting mechanism 60, the cutting mechanism 60 cuts along a second cutting line 1C' (a virtual cutting line). Then, the waste material 1B is completely pulled into the receiving opening 100 under the action of the gravity at its front end. The lifting air cylinder 71 drives the cover plate 72 to move downward to be flush with the rear feeding table 32. The rear formed material 1A" near the second cutting line 1C' and the film material at its rear end continue to be pulled forward by the front auxiliary roller group 51, are located at the upper end of the rear feeding table 32, and stop moving forward when reaching below the tape sticking module 83 and making the second cutting line 1C' adjacent to and in contact with the first cutting line 1C. The tape sticking module 83 drives the movement through a moving module 82 to paste the connection part between the first cutting line 1C and the second cutting line 1C'. After the rear formed material 1A" is connected to the front formed material 1A', it is then wound and collected by the rear receiving roller 22. It should be noted that: since the cutting of the waste material area 1B' is to cut the entire material area defined as waste material 1B, the waste material 1B, the front formed material 1A', the rear formed material A", etc. all have the same length, that is, the length between the first cutting line 1C and the second cutting line 1C'. Therefore, the accurate docking of the rear formed material 1A" and the front formed material 1A' can be realized by the feeding of the receiving roller 22, the front auxiliary roller group 51, etc. controlled by a servo motor.

[0031] Through the functions of the detection mechanism 50, the cutting mechanism 60, and the collection mechanism 70 in the present utility model, the waste material 1B can be cut and collected after being cut. Through the feeding of the front auxiliary roller group 51, the receiving of the rear receiving roller 22, and the connection of the cut film material by the material receiving mechanism 80 (tape sticking module 83) and then continuing to receive the material, the continuous receiving and winding of the material after cutting the waste material 1B on the continuous film material 1A are realized, thereby improving the automation level of the material receiving.

[0032] More specifically, the material cutting mechanism 60 includes a cutting cylinder 61, a cutting knife 62, and a base 63. The base 63 and the cutting cylinder 61 are arranged on the machine table 10, and the base 63 is flush with the front / rear feeding table. The cutting knife 62 is arranged at the output end of the cutting cylinder 61 to cut the continuous film material 1A passing through the base 63. The base 63 can play a supporting role when cutting the continuous film material 1A; and gaps can be provided on the base 63 to avoid the cutting edge of the cutting knife 62.

[0033] To ensure accurate visual inspection of the defective area 1B' on the continuous film material 1A, a first adsorption area 310 can be set on the front feeding table 31. The continuous film material 1A is flattened through the pulling action of the front auxiliary roller group 51 and the first adsorption area 310, and the defective area 1B' can be identified more accurately; to ensure accurate tape pasting and material connection between the rear formed material 1A" and the front formed material 1A', a second adsorption area 320 can be set below the tape pasting module 83 on the rear feeding table 32 to adsorb and fix the rear formed material 1A" and the front formed material 1A'; of course, the second adsorption area 320 can also play an adsorption and fixing role when the first cutting line 1C on the cut film material moves onto it.

[0034] Similarly, a pair of material pressing mechanisms 90 can also be included. The pair of material pressing mechanisms 90 are respectively arranged at both ends of the rear feeding table 32. The material pressing mechanism 90 includes a material pressing cylinder 91 and a pressing rod 92. The material pressing cylinder 91 is arranged on the machine table 10, and the pressing rod 92 is arranged at the output end of the material pressing cylinder 91 to press the film material located on the rear feeding table 32, and can also fix the film material; of course, the material pressing mechanism closer to the winding roller 22 can also press and fix the film material when the first cutting line 1C on the cut film material moves to the corresponding position on the rear feeding table 22.

[0035] In addition, a rear auxiliary roller group 52 can be set. It is arranged on the machine table 10 and behind the rear feeding table 22 to drive the continuous film material for transportation, and the setting of the rear auxiliary roller group 52 also facilitates the control of the positioning of the film material on the rear feeding table 22.

[0036] Regarding the specific structure of the material connection mechanism 80, its moving module 82 includes an electric cylinder and a vertically arranged cylinder. A bracket 81 is provided on the machine table 10. The electric cylinder is arranged on the bracket 81, and the vertically arranged cylinder is arranged at the output end of the electric cylinder, and a tape pasting module 83 is provided at the output end. The electric cylinder and the vertically arranged cylinder cooperate to drive the tape pasting module 83 to move in the horizontal and vertical directions.

[0037] Combined with Figure 4 and 5As shown, the specific structure of the tape - sticking module 83 is as follows: it includes a first mounting plate 8301. The first mounting plate 8301 is arranged at the output end of the vertical electric cylinder. One side of it is provided with a winding shaft 8302, and the tape roll 800a is sleeved on the winding shaft 8302. A connecting plate 831 is hinged on the first mounting plate 8301. The other end of the connecting plate 831 is connected to a first air cylinder 832 arranged on the first mounting plate 8301. And a feeding guide assembly 833 is arranged on the connecting plate 831 near its connection with the first air cylinder 832. The tape 800b passes through the feeding guide assembly 833 and is pressed against the film material (the first cutting line 1C and the second cutting line 1C′). The output end of a second air cylinder 834 on a second mounting plate 8302 on one side of the first mounting plate 8301 is provided with a pressure roller 835. The pressure roller 835 is close to the feeding guide assembly 833 and is driven to press the tape 800b tightly. The output end of a third air cylinder 836 on a second mounting plate 8303 is provided with a scissor air cylinder 837. The scissor air cylinder 837 is driven to cut the tape located between the pressure roller 835 and the feeding guide assembly 833. The specific working process of the tape - sticking module 83 is as follows: The first air cylinder 832 drives the feeding guide assembly 833 to press the tape 800b against the end position at the connection of the first cutting line 1C and the second cutting line 1C′. The vertical air cylinder and the tape - sticking module 83 are driven to translate by the electric cylinder. During the translation process, since the end of the tape 800b is pressed and adhered to the film material, the feeding guide assembly 833 can drive the tape at the rear position to be adhered to the film material during the translation process, and force the tape roll 800a to continuously feed the tape to be pressed against the film material for adhesion until the other end position at the connection of the first cutting line 1C and the second cutting line 1C′. During this process, the second air cylinder 834 can drive the pressure roller 835 to move down to abut against the tape 800b to further press it. Then the first air cylinder 832 drives the feeding guide assembly 833 to lift a certain distance. The third air cylinder 836 drives the scissor air cylinder 837 to extend between the feeding guide assembly 833 and the pressure roller 835, and the scissor air cylinder 837 cuts the tape. (Or further, the pressure roller 835 is driven by the electric cylinder to continue to translate a certain distance to press the cut tape against the film material), thus completing the re - connection of the film material.

[0038] More specifically, the material guiding assembly 833 includes a first material guiding wheel 8331, a second material guiding wheel 8332, and a limiting plate 8333. The first material guiding wheel 8331 is arranged on one side of the connecting plate 831 close to the material pressing wheel 835 through a first rotating shaft 833a on the connecting plate 831. The second material guiding wheel 8332 is arranged on the other side of the connecting plate 831 through a first rotating shaft 833b on the connecting plate 831. The bottom ends of the first material guiding wheel 8331 and the second material guiding wheel 8332 are respectively abutted against the upper surface of the tape 800b. The limiting plate 8333 is provided with an anti-sticking coating, which is arranged on the connecting plate 831 to abut against the lower surface of the tape 800b to prevent the tape from moving away from the first guiding wheel 8331 without support when the tape is not attached, thus affecting the pressing action of the first guiding wheel 8331 on the tape.

[0039] The material guiding assembly 833 further includes an adsorption plate 8334. The adsorption plate 8334 is arranged between the first material guiding wheel 8331 and the second material guiding wheel 8332 for adsorbing the tape. Specifically, a middle cavity 8330 is provided in the middle of the adsorption plate 8334, and a vacuum suction head 8330' communicating with the middle cavity 8330 is provided on one side of the adsorption plate 8334. Adsorption holes 8330'' communicating with the middle cavity 8330 are provided in a matrix on the other side. Through the negative pressure adsorption action of the vacuum suction head 8330', the middle cavity 8330, and the adsorption holes 8330'', the tape 800b can be positioned within the material guiding assembly 833. Acting together with the limiting plate 8333, it ensures the position of the tape 800 and its end so that the first material guiding wheel 8331 can accurately act on the end position of the tape 800b when the tape is attached next time.
