Description

Technical Field

[0001] The invention specifically relates to a low-energy-consumption and low-loss pin-moving type preform separating device. Background Art

[0002] Plastic bottles are common containers in daily life. The common method of making plastic bottles is to blow a test tube-shaped preform into a bottle with a predetermined shape. The current blow molding equipment includes a preform feeding device, a heating device, a bottle blowing device and a bottle discharging device, and each device is sequentially connected in series by a conveying track. The preform is first transferred from the preform feeding device to the conveying track, and then the preform is heated and softened by the heating device, and then blown into shape by the bottle blowing device, and finally the finished product is taken out by the bottle discharging device.

[0003] In order to reduce the loss of heat energy and fully improve the heat utilization rate of the heating device, the spacing between the preforms in the heating device is as small as possible for heating; because the spacing between the cavities in the mold is relatively large, it is required that before the preforms are sent into the mold, the spacing between the preforms needs to be adjusted so that the spacing between the preforms corresponds to the spacing between the cavities in the mold; therefore, in the prior art, the variable pitch screw is generally driven by a motor, and the screw drives the preform clamping device, and the pitch adjustment of the preform is achieved through the different pitches of the screw. This prior art has the following shortcomings: a separate motor is required as a support system, which has high energy consumption and high loss; the variable pitch screw is complex to process, has high cost, and is easy to wear; in addition, the clamping device has a complex structure and is easy to hit, which makes the preforms prone to failure during the process of taking, separating and sending the preforms. Summary of the invention

[0004] In view of the deficiencies in the prior art, the object of the present invention is to provide a low-energy-consumption and low-loss pin-moving preform separating device.

[0031] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0032] Example

[0033] like Figure 1-9 As shown, a low-energy consumption and low-loss pin-type embryo separation device comprises a pin-type embryo separation device 1, an embryo removal structure 2 fixedly mounted with the pin-type embryo separation device 1, a bottle preform 3 located inside the embryo removal structure 2 and driven and transported by the pin-type embryo separation device 1, and a bottle preform chuck 4 for delivering the bottle preform 3 into the embryo removal structure 2. The pin-type embryo separation device 1 comprises a frame 11, a track strip 12 mounted on the frame 11, a plurality of pin-type embryo separation assemblies 13 fixedly mounted on the track strip 12 and equidistantly distributed, and a plurality of pin-type embryo separation assemblies 13 fixed on the frame 11 and equidistantly distributed. The straight groove guide rails 14 at the lower sides of the frame 12 are used to support the guide needle embryo separation assembly 13, and the dial 15 located above the frame 11 and assembled with the power device of the driving track strip 12. The embryo removal structure 2 includes a supporting foot 21, a first embryo removal frame 22 fixedly installed with the supporting foot 21, a second embryo removal frame 23 fixedly installed with the frame 11 and arranged parallel to the first embryo removal frame 22, and a third embryo removal frame 24 fixedly installed with the frame 11 and on the same straight line with the second embryo removal frame 23.

[0034] The needle-shifting splitter assembly 13 includes a support block 131 fixedly mounted on the track strip 12, a guide pulley 132 mounted on the lower end of the support block 131, an assembly seat 133 fixedly mounted on the upper side of the support block 131 by bolts, a rotating shaft 134 inserted in the center of the assembly seat 133 and having a slot at the upper end, a needle-shifting splitter assembly 135 clamped in the slot at the upper end of the rotating shaft 134, a first magnet 136 fixedly mounted on one side of the upper side of the assembly seat 133 by bolts, and a second magnet 137 fixedly mounted on the other side of the upper side of the assembly seat 133 by bolts.

[0035] In the present embodiment, two guide pulleys 12 are provided. Specifically, the guide pulleys 12 can be assembled with the straight groove guide rails 14 of the needle-shifting embryo-separating device 1, which can further improve the working stability of the needle-shifting embryo-separating device 1.

[0036] A fixing bolt 1311 is disposed at the center of the support block 131, and a vertical groove 1312 is provided on the back side of the support block 131. Specifically, the support block 131 is clamped with the track strip 12 of the preform separating device through the vertical groove 1312, and then the fixing bolt 1311 penetrates the support block 131 and is screwed into the track strip 12 for fixing. When the track strip 12 moves, the support block 131 is driven to move, and the pin 135 abuts against the preform 3, and the preform 3 is pushed to move.

[0037] The portion of the assembly seat 133 corresponding to the first magnet 136 is convex and has an embedding groove 1331. Specifically, since the pin 135 needs to push the preform 3 to move forward, the pin 135 needs to be fixed by the first magnet 136 and the convex portion of the assembly seat 133 is also needed to stably support the pin 135.

[0038] The space between the first magnet 136 and the second magnet 137 is a sector-shaped area where the setting needle 135 rotates. Specifically, the setting needle can rotate in the sector-shaped area with the rotating shaft 134 as the center point.

[0039] It should be further explained that the dial 15 and the track strip 12 are driven to rotate synchronously, so that when the dial 15 rotates, the paddle on the dial 15 cooperates with the paddle pin 135 to perform the material paddle operation, so that the paddle contacts the preform 3 entering from the preform removal structure 2 and moves forward one station, which further facilitates the paddle pin 135 to abut against the preform 3 and push the preform 3 to move forward.

[0040] A strip groove 211 is formed at the portion where the support foot 21 contacts the ground. Specifically, the installation position of the support foot 21 can be adjusted through the strip groove 211, so that the support foot 21 drives the first embryo retrieval rack 22 to move closer to and then away from the second embryo retrieval rack 23 and the third embryo retrieval rack 24, so as to accommodate the transport and placement of bottle embryos 3 of different sizes.

[0041] The first embryo taking frame 22 comprises an L-shaped steel seat 221 fixedly mounted on the supporting foot 21 by bolts, an embryo feeding section 222 fixedly mounted on the front end of the L-shaped steel seat 221 by bolts and cooperating with the second embryo taking frame 23 to place the bottle embryo, an L-shaped pad steel 223 fixedly mounted on the L-shaped steel seat 221 by bolts and used for docking and supporting the bottle embryo, and an embryo conveying section 224 fixedly mounted on the L-shaped steel seat 221 by bolts and cooperating with the third embryo taking frame 24 to convey the bottle embryo.

[0042] The embryo entry section 222 includes an embryo entry section bottom plate 2221 which is stacked on the upper surface of the L-shaped steel seat 221 and has the same thickness as the L-shaped pad steel 223, an embryo entry section middle plate 2222 which is stacked on the upper surface of the embryo entry section bottom plate 2221 and has a width smaller than that of the embryo entry section bottom plate 2221, and an embryo entry section panel 2223 which is stacked on the upper surface of the embryo entry section middle plate 2222 and has the same size as the embryo entry section panel 2223. The embryo entry section bottom plate 2221, the embryo entry section middle plate 2222 and one side of the embryo entry section panel 2223 are placed flush, and a clamping groove is formed on the other side due to the small width of the embryo entry section middle plate 2222. Specifically, the clamping groove can cooperate with the wing edge of the bottle preform 3, so that the bottle preform 3 is separated from the bottle preform clamp 4 when the bottle preform 3 is sent into the first embryo removal rack 22 and the second embryo removal rack 23.

[0043] The embryo delivery section 224 includes an L-shaped embryo delivery section bottom plate 2241 which is stacked on the upper surface of the L-shaped steel seat 221 and has a width smaller than the L-shaped steel seat 221, and an L-shaped embryo delivery section panel 2242 which is stacked on the upper surface of the L-shaped embryo delivery section bottom plate 2241 and has a width consistent with the L-shaped steel seat 221. The thickness of the L-shaped embryo delivery section bottom plate 2241 is consistent with the L-shaped pad steel 223, so that the bottle embryo 3 can enter the embryo delivery section 224 through the L-shaped pad steel 223. , and one side of the L-shaped embryo-feeding section bottom plate 2241 and the L-shaped embryo-feeding section panel 2242 are placed flush, and on the other side, due to the small width of the L-shaped embryo-feeding section bottom plate 2241, a clamping groove is formed between the L-shaped embryo-feeding section panel 2242 and the L-shaped steel seat 221. Specifically, the clamping groove can cooperate with the wing edge of the bottle preform 3, and when the bottle preform 3 is fed into the first embryo-taking rack 22 and the third embryo-taking rack 24 area, the bottle preform 3 is pushed by the pin 135 to be separated and transported.

[0044] One end of the L-shaped embryo delivery section panel 2242 facing the L-shaped pad steel 223 is also tilted upward to provide an embryo delivery section anti-falling and warping edge 22421 . Specifically, the embryo delivery section anti-falling and warping edge 22421 can prevent the bottle preform 3 from falling off the embryo delivery section 224 .

[0045] The second embryo rack 23 includes a second embryo rack bottom plate 231 fixedly installed with the frame 11 by bolts, a second embryo rack middle plate 232 stacked on the upper surface of the second embryo rack bottom plate 231 and having a smaller width than the second embryo rack bottom plate 231, and a second embryo rack panel 233 stacked on the upper surface of the second embryo rack middle plate 232 and having the same size as the second embryo rack bottom plate 231. The second embryo rack bottom plate 231, the second embryo rack middle plate 232 and the second embryo rack panel 233 are placed flush on one side, and a clamping groove is formed between the second embryo rack bottom plate 231 and the second embryo rack panel 233 on the other side due to the small width of the second embryo rack middle plate 232. Specifically, the clamping groove can cooperate with the wing edge of the bottle preform 3, so that the bottle preform 3 is separated from the bottle preform chuck 4 when the bottle preform 3 is fed into the first embryo rack 22 and the second embryo rack 23.

[0046] The third embryo taking frame 24 includes a third embryo taking frame bottom plate 241 fixedly installed with the frame 11 by bolts and abutting against the second embryo taking frame 23, and a third embryo taking frame panel 242 stacked on the upper surface of the third embryo taking frame bottom plate 241. The width of the third embryo taking frame panel 242 is greater than the third embryo taking frame bottom plate 241. The outer side of the third embryo taking frame panel 242 is placed flush with the third embryo taking frame bottom plate 241. The inner side of the third embryo taking frame panel 242 covers the third embryo taking frame bottom plate 241 and extends toward the first embryo taking frame 22. Specifically, the third embryo taking frame panel 242 is used to press down the wing edge of the bottle embryo 3 to prevent the bottle embryo 3 from tilting and detaching from the embryo taking structure 2. At the same time, since there is no clamping groove in the third embryo taking frame 24, the third embryo taking frame panel 242 cooperates with the pin 135 to support the bottle embryo 3.

[0047] One end of the third embryo retrieval rack panel 242 facing the second embryo retrieval rack 23 is also tilted upward to be provided with a third embryo retrieval rack anti-falling and warping edge 2421 . Specifically, the third embryo retrieval rack anti-falling and warping edge 2421 can prevent the bottle preforms 3 from falling off the third embryo retrieval rack 24 .

[0048] like Fig.10 As shown, the paddle on the dial 15 cooperates with the paddle pin 135 to perform the paddle operation, so that the paddle contacts the preform 3 entering from the preform taking structure 2 and moves forward one station. The preform 3 is unable to move due to resistance in the preform taking structure 2. At this time, the paddle pin 135 abuts against the preform 3. At this time, due to the resistance of the preform 3, the paddle pin 135 rotates in the direction A, contacts the first magnet 136 and is adsorbed and fixed by the first magnet 136, and then pushes the preform 3 to move forward. When the external robot takes out the preform, the robot drives the preform to push the paddle pin 135 in front, so that it separates from the first magnet 136 and rotates in the direction B to approach the second magnet 137, abuts against the second magnet 137 and is adsorbed and fixed by the second magnet 137 to achieve reset, and prepares for the next round of preform pushing.

All other modifications, replacements or changes made to the above structures of the present invention based on the above contents of the present invention, in accordance with common technical knowledge and customary means in the art, without departing from the above basic technical ideas of the present invention, should fall within the protection scope of the present invention.
