Description

Technical Field

[0001] This utility model belongs to the field of PVC film processing technology, and more specifically, it relates to a color matching device for PVC blister film. Background Technology

[0002] In the production of PVC blister film, precise color matching is crucial. Existing PVC blister film color matching methods suffer from several problems, such as low accuracy leading to color deviations that affect product quality; low efficiency, resulting in time-consuming and labor-intensive processes that increase production costs; and a lack of flexible color matching solutions, making it difficult to meet diverse color requirements. To overcome these shortcomings, the development of a new type of color matching device for PVC blister film is urgently needed. This device must possess high precision, high efficiency, and high flexibility to improve the color matching level in PVC blister film production.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] like Figures 1 to 11 As shown, a color mixing device for PVC blister film can individually mix pigments in multiple containers 501. It includes a rotating mechanism 1, a stirring mechanism 3, a color mixing mechanism 4, and a dispensing mechanism 5. The rotating mechanism 1 includes a rectangular base 101 with a toothed ring 102 in the center. A driving mechanism 109 is fixedly connected to the center of the toothed ring 102. The driving mechanism 109 includes a driving device 1091 fixed to the base 101. A tray 108 fixedly connected to the base 101 is provided on the outside of the driving device 1091. A toothed disc 1 is fixedly connected to the extended end of the driving device 1091. 092, the toothed disc 1092 is flush with the toothed ring 102. A fixed post 1093 is fixedly connected to one end of the toothed disc 1092, and a first hexagonal block 1094 is fixedly connected to one end of the fixed post 1093. A ring groove 1082 is opened on the side of the tray 108 near the outer ring. A slot 1081 is opened between the ring groove 1082 and the outer side of the tray 108, so that the pot 501 can enter the ring groove 1082 through the slot 1081 and slide in the ring groove 1082. The tray 108 has a central hole 1083 in the middle, which cooperates with the drive device 1091. That is, the drive device 1091 can be installed in the central hole 1083, which can reduce the overall height. The base 101 is fixedly connected to the pivot hole 107 and the hexagonal prism 2 at both ends, respectively. The color mixing mechanism 4 is rotatably connected to the upper part of the pivot hole 107, and the stirring mechanism 3 is slidably connected to the upper part of the hexagonal prism 2.

[0031] like Figures 6 to 10As shown, the stirring mechanism 3 includes a support frame 302 that is slidably connected to the hexagonal prism 2. A positioning chuck 304 is slidably connected to one end of the support frame 302. A fixed plate 303 is slidably connected to the upper end of the positioning chuck 304. Multiple stirring devices 305 are fixedly connected to the positioning chuck 304. The support frame 302 includes a connecting column 3023. A hexagonal hole 3021 that mates with the hexagonal prism 2 is opened in the middle of the connecting column 3023. A locking hole 3022 is opened on the side of the connecting column 3023. A locking pin 301 is slidably connected in the locking hole 3022. The function of the locking pin 301 is to connect and fix the support frame 302 and the hexagonal prism 2. A bracket 3024 is fixedly connected to one side of the connecting column 3023, and an arc-shaped slider 3025 is fixedly connected to one end of the bracket 3024. The positioning chuck 304 has multiple hexagonal through slots 3042 on its outer side. The inner side of each hexagonal through slot 3042 is a hexagonal groove, and the outer side is an arc-shaped slot. A second limiting post 3041 is fixedly connected to the positioning chuck 304 between every two hexagonal through slots 3042. A circular slide rail 3043 is formed inside each hexagonal through slot 3042. The arc-shaped slider 3025 is slidably connected to the circular slide rail 3043. The support frame 302 supports the positioning chuck 304 without affecting its rotation. A hexagonal through hole 3044 is formed in the center of the positioning chuck 304, and the hexagonal through hole 3044 is slidably connected to the first hexagonal block 1094. When the gear plate 1092 rotates, the positioning chuck 304 also rotates synchronously. The upper end of the positioning chuck 304 is movably connected to the fixed plate 303. The fixed plate 303 has multiple holes 3031. The holes 3031 are slidably connected to the second limiting post 3041, which fixes the stirring device 305 installed on the positioning chuck 304 and prevents the stirring device 305 from disengaging when the positioning chuck 304 rotates.

[0032] like Figure 8 As shown, the stirring device 305 includes a second hexagonal block 3051 that mates with a hexagonal through slot 3042. The upper end of the second hexagonal block 3051 abuts against the fixed plate 303. A shaft 3052 is fixedly connected to the bottom of the second hexagonal block 3051. Multiple stirring rods 3054 are fixedly connected to the bottom of the shaft 3052. A lid 3053 is fixedly connected to the upper end of the stirring rods 3054 on the shaft 3052, and the lid 3053 seals the pot 501. The multiple stirring rods 3054 are perpendicular to the shaft 3052, which thoroughly stirs the pigment inside the pot 501.

[0033] The upper side of the hexagonal prism 2 is provided with multiple positioning holes 202, and the locking pin 301 is slidably connected to the positioning holes 202. A cylinder 201 is fixedly connected to the middle of the hexagonal prism 2, and the bottom of the connecting column 3023 abuts against the top of the cylinder 201.

[0034] like Figure 3As shown, the other end of the base 101 is provided with an opening that connects the gear ring 102 to the outside. A first limiting post 103 is fixedly connected to one end of the opening. A rotating rack 104 is rotatably connected to the first limiting post 103. One end of the rotating rack 104 is provided with a first limiting hole 1041 that cooperates with the first limiting post 103. The rotating rack 104 is provided with an arc-shaped tooth 1043 on the side near the gear ring 102, which forms a circle with the gear ring 102, so that the pot 501 can rotate inside without detaching. A rotation limiter 1042 is fixedly connected to the upper end of the rotating rack 104. A wrench 105 is rotatably connected to the rotation limiter 1042. One end of the wrench 105 has a rotation hole 1051 that mates with the rotation limiter 1042. A locking slot 1052 is provided on one side of the wrench 105. A locking tongue 106 is fixedly connected to the corresponding base 101 to cooperate with it. The locking slot 1052 and the locking tongue 106 lock the rack 104 to prevent it from being pushed out when the pot 501 rotates to the position of the rotating rack 104. This serves to fix the rotating rack 104.

[0035] like Figure 11 As shown, the holding mechanism 5 includes a pot 501. A gear 502 is fixedly connected to the bottom of the pot 501. The gear 502 meshes with a gear disc 1092 and a gear ring 102 for transmission. Through the rotation of the gear disc 1092 and the engagement of the gear ring 102, the pot 501 can revolve around the gear disc 1092 and rotate on its own axis. A third limiting post 503 is fixedly connected to the bottom of the gear 502. The third limiting post 503 is slidably connected to an annular groove 1082. The annular groove 1082 not only allows the third limiting post 503 to rotate inside, but also acts as a stop for the third limiting post 503 and the pot 501. The number of pots 501 is the same as the number of stirring devices 305. The axis of the pot 501 is collinear with the axis of the stirring device 305, so that each pot 501 corresponds to one stirring device 305, which thoroughly stirs the pigment inside the pot 501.

[0036] like Figure 2As shown, the color mixing mechanism 4 includes a rotating shaft 403 rotatably connected to the rotating shaft hole 107. A placement rack 402 is fixedly connected to the upper end of the rotating shaft 403. Multiple pigment pots 401 are fixedly connected to the placement rack 402. A pump body is fixedly connected to the bottom of each pigment pot 401. The outlet of the pump body is interconnected. In this utility model, three pigment pots 401 are connected together in series using a four-way pipe and then connected to a pigment tube 404. If more pigment pots 401 are needed, the corresponding connecting pipe can be replaced to connect them in series. One end of the placement rack 402 is connected to a pigment tube 404. The pigment tube 404 is sealed to the outlet of the pump body. The pigment tube 404 is located above the pot 501. The advantage of this is that only one pigment tube 404 is located above the pot 501. Different colors of pigment are filled into the pot 501 for mixing. From the outside, it looks simpler and more beautiful.

[0037] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.

[0038] Working principle: First, slide the stirring mechanism 3 upwards. When it reaches a suitable height, insert the locking pin 301 into the appropriate positioning hole 202 of the hexagonal prism 2 to fix the stirring mechanism 3. Select a suitable pot 501, turn the wrench 105 to separate the locking jaw 1052 from the locking tongue 106, rotate the rotating rack 104 to slide the gear 502 and the third limiting post 503 at the bottom of the pot 501 from the slot 1081 of the tray 108 into the annular groove 1082, rotate the gear plate 1092 to make the pot 501 slide into the interior, and slide the required pots 501 in sequence (it is best to have an even number of pots 501, and place them in pairs to prevent uneven force when rotating). After placing the required pots 501, turn off the rotating rack 104 and fix the wrench 105 back in its original position. Lift the fixing plate 303 to separate it from the positioning chuck 304. Place the stirring device 305 above each pot 501 so that the second hexagonal block 3051 enters the hexagonal through groove 3042. Loosen the fixing plate 303 so that the second limiting post 3041 enters the hole 3031 for fixation. Start the pump at the bottom of the pigment pot 401 to pump the pigment from the pigment pot 401 into the pot 501 through the pigment tube 404 according to the set ratio. When the pigment is placed in a pot 501, the driving device 1091 drives the toothed disc 1092 to rotate, which drives the pot 501 to rotate and prepare the pigment for the next pot 501.

[0039] The second step involves releasing the locking pin 301 after each pot 501 has been filled with pigment. The fixing pin 3032 in the stirring mechanism 3 is then placed onto the cylinder 201, and the locking pin 301 is reinserted to secure it. The pot lid 3053 covers the pot 501, sealing it and preventing pigment from flying out during mixing. The drive device 1091 is then activated, causing the gear plate 1092 to rotate, which in turn rotates the pot 501. The first hexagonal block 1094 at the upper end of the gear plate 1092 drives the positioning chuck 304 to rotate synchronously. Since the pot 501 rotates both on its own axis and revolves around the sun, it is in a rotating state relative to the stirring device 305, meaning the stirring rod 3054 can stir the pigment inside the pot 501. It is worth noting that before the drive device 1091 rotates, the color mixing mechanism 4 is rotated at an angle so that the paint tube 404 is not above the pot 501. The advantage of this is that the pot lid 3053 can be tightly connected to the pot 501, and the pot 501 will not collide with the paint tube 404 when it rotates.

[0040] Third, after stirring is finished, stop the drive device 1091, pull out the locking pin 301, lift the stirring mechanism 3 upward, separate the pot 501 from the pot lid 3053, open the wrench 105, rotate the rotating rack 104, and you can remove the pots 501 from the base 101 one by one to complete the color mixing operation.

[0041] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
