Description

[Technical Field]

[0001] This utility model relates to the field of blow molding machine technology, specifically to a blow molding machine preform removal device that can be adapted to different preform teeth. [Background Technology]

[0002] A blow molding machine is an industrial piece of equipment that processes plastic granules or preforms into hollow containers using a blow molding process. It is widely used in the beverage, cosmetics, and pharmaceutical industries. The basic process of a blow molding machine includes heating and softening plastic granules or preforming preforms → placing them in a mold → injecting compressed air to inflate and shape the preform → cooling and demolding. Traditional blow molding machines generally suffer from limited applicability in their preform removal devices. These devices are fixed and non-adjustable, unable to adapt to different preform thread sizes (such as differences in support ring height and outer diameter), requiring frequent replacement of the removal components, resulting in low removal efficiency.

[0003] In view of this, this case involves in-depth research into the aforementioned issues, which led to the formation of this case. [Utility Model Content]

[0004] This invention aims to solve the aforementioned technical problems of existing blow molding machines by providing a blow molding machine preform removal device that can adapt to different preform nipple sizes. Through the combination of elongated holes, threaded holes, and bolt assemblies, the traditional "fixed preform removal" is upgraded to "adaptive preform removal," achieving stepless horizontal adjustment of the preform removal pressure plate, accurately adapting to different preform nipple sizes, and forcibly limiting the preform support ring, fundamentally solving the problems of narrow applicability and preform removal failure.

[0005] This utility model is implemented as follows: a blow molding machine preform removal device adaptable to different preform teeth, including a fixed frame, a preform removal pressure plate, and a bolt assembly for detachably connecting the fixed frame and the preform removal pressure plate; the fixed frame includes at least one longitudinal connecting plate, and the bottom surface of the longitudinal connecting plate has a threaded hole; the preform removal pressure plate is vertically connected to the bottom surface of the longitudinal connecting plate by the bolt assembly, and an extension plate for positioning the preform support ring is fixed on the side of the preform removal pressure plate near the preform, and the preform removal pressure plate has a through hole, and the threaded hole and the through hole are arranged vertically and vertically respectively.

[0006] Furthermore, the bottom surface of the longitudinal connecting plate has two threaded holes arranged side by side; the blanking plate has two elongated holes that pass through the two threaded holes.

[0007] Furthermore, there are three longitudinal connecting plates, which are arranged side by side along the length of the demolding pressing plate.

[0008] Furthermore, the preform removal device also includes a connecting frame, which includes a gantry frame and a connecting plate. The gantry frame is fixedly connected to the preform conveying device, one end of the connecting plate is fixedly connected to the gantry frame, the other end of the connecting plate is fixedly connected to the preform conveying device, and the middle part of the connecting plate is fixedly connected to the upper part of multiple longitudinal connecting plates.

[0009] The advantages of this utility model are:

[0010] 1. The blow molding machine de-premium device of Example 1, adaptable to different preform nipples, upgrades the traditional "fixed de-premium" to "adaptive de-premium" through the combination of elongated holes, threaded holes, and bolt assemblies. This achieves stepless horizontal adjustment of the de-premium pressure plate, precisely adapting to different preform nipple sizes, and forcibly limiting the preform support ring, fundamentally solving the problems of narrow applicability and de-premium failure. The extension plate vertically presses against the preform support ring to prevent slippage and ensure a high de-premium success rate; the extension plate can be customized in shape for special preforms and is compatible with irregularly shaped support rings. Three longitudinal connecting plates are evenly distributed along the length of the de-premium pressure plate, dispersing the de-premium force and preventing deformation of the pressure plate; multiple sets of parallel threaded holes and elongated holes provide more positioning points, enhancing adjustment accuracy and operational error tolerance; the gantry frame + connecting plate double-fixed design rigidly connects the de-premium device to the conveying device, resisting mechanical vibration interference.

[0011] 2. The adjustable automatic preform removal and de-preg blowing machine of Example 2 changes the preform removal method to mechanical preform removal. The pressure plate of the preform removal device forcibly clamps the preform support ring, eliminating the risk of preform slippage and achieving high-stability preform removal. The adjustable pressure plate and adaptive preform removal gripper are compatible with preforms of various specifications, improving the applicability of the blowing machine. The conveying device, preform removal device and preform removal device 300 work together to achieve precise linkage of preform removal and de-preg actions, improving production efficiency.

Detailed Implementation Methods

[0027] To better understand the technical solution of this utility model, the technical solution of this utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Example 1

[0029] Reference Appendix Figure 1-4As shown, this embodiment provides a blow molding machine preform removal device 300 adaptable to different preform teeth, including a fixed frame 8, a preform removal pressure plate 7, and a bolt assembly detachably connecting the fixed frame 8 and the preform removal pressure plate 7. The fixed frame 8 includes at least one longitudinal connecting plate 81, with a threaded hole 82 on its bottom surface. The preform removal pressure plate 7 is vertically connected to the bottom surface of the longitudinal connecting plate 81 via the bolt assembly. An extension plate 71 for positioning a preform support ring 401 is fixed on the side of the preform removal pressure plate 7 near the preform 400. The extension plate 71 presses down on the support ring 401, achieving precise positioning of the preform support ring 401. The preform removal pressure plate 7 has a through-hole 72, with the threaded hole 82 and the through-hole 72 corresponding vertically. During adjustment, align the elongated hole 72 with the threaded hole 82 according to the size of the preform 400 thread or the support ring 401. Manually change the alignment position of the threaded hole 82 and the elongated hole 72 to move the extension plate 71 closer to or further away from the mounting head 2. Then, use the bolt assembly to lock the preform removal plate 7 and the fixing bracket 8. The preform removal plate 7 of the preform removal device 300 is horizontally adjustable via the elongated hole 72 and the bolt assembly to accommodate different preform 400 thread sizes or support rings 401 of different sizes.

[0030] In this embodiment, the bottom surface of the longitudinal connecting plate 81 has two threaded holes 82 arranged side by side; the blanking plate 7 has two elongated holes 72 through the two threaded holes 82.

[0031] In this embodiment, there are three longitudinal connecting plates 81, which are arranged side by side along the length of the de-embryo pressing plate 7.

[0032] In this embodiment, the preform removal device 300 further includes a connecting frame 9, which includes a gantry frame 91 and a connecting plate 92. The gantry frame 91 is fixedly connected to the preform conveying device 100. One end of the connecting plate 92 is fixedly connected to the gantry frame 91, and the other end of the connecting plate 92 is fixedly connected to the preform conveying device 100. The middle part of the connecting plate 92 is fixedly connected to the upper part of a plurality of longitudinal connecting plates 82.

[0033] The blow molding machine preform removal device 300, which is adaptable to different preform teeth in this embodiment, has the following beneficial technical effects:

[0034] 1. By using the combination of elongated hole 72, threaded hole 82, and bolt assembly, the traditional "fixed preform removal" is upgraded to "adaptive preform removal," achieving stepless horizontal adjustment of the preform removal pressure plate 7 to precisely adapt to different preform thread sizes (such as differences in the height / outer diameter of the support ring 401), and can forcibly limit the preform support ring 401, fundamentally solving the problems of narrow applicability and preform removal failure. The extension plate 71 vertically presses the preform support ring 401 to prevent slippage and ensure a high preform removal success rate; the extension plate 71 can be designed with customized shapes (such as arc / serrated) for special preforms, and is compatible with irregularly shaped support rings 401.

[0035] 2. Adaptation can be completed simply by manually adjusting the position of the bolt assembly, without the need to replace parts, greatly reducing downtime for adjustment.

[0036] 3. Three longitudinal connecting plates 81 are evenly distributed along the length of the demolding pressure plate 7 to disperse the demolding force and prevent the demolding pressure plate 7 from deforming; multiple sets of parallel threaded holes 82 and elongated holes 72 provide more positioning points, enhancing adjustment accuracy and operational fault tolerance; the double-fixed design of gantry frame 91 + connecting plate 92 rigidly connects the demolding device 300 to the conveying device 100, resisting mechanical vibration interference.

[0037] Example 2

[0038] Please see Figure 1-10 As shown in the figure, this embodiment provides an adjustable automatic preform removal and de-preg blowing machine, including a conveying device 100 for conveying preforms 400, a preform removal device 200, and a de-preg removal device 300. The structure of the de-preg removal device 300 is shown in Embodiment 1. The conveying device 100 includes an annular conveying assembly 1 and a plurality of mounting heads 2 mounted on the annular conveying assembly 1 for mounting the preforms 400; the annular conveying assembly 1 drives the mounting heads 2 to move, and the preforms 400 are fixed on the preform insertion heads 211 of the mounting heads 2. The preform removal device 200 is located above the annular conveying assembly 1. The preform removal device 200 includes a left clamp 3 and a right clamp 4 that clamp the upper part of the mounting head 2, and a driving assembly 5 that drives the left clamp 3, the right clamp 4, and the mounting head 2 to rise simultaneously; the washers 24 of the plurality of mounting heads 2 enter between the left clamp 3 and the right clamp 4 and are clamped by the left clamp 3 and the right clamp 4, and the driving assembly 5 drives the left clamp 3, the right clamp 4, and the mounting head 2 to rise simultaneously. The preform removal device 300 is located on the side of the annular conveying assembly 1 and below the preform removal device 200. The preform removal device 300 includes a pressure plate 7 for pressing down the preform 400. The pressure plate 7 is higher than the height of the preform 400 support ring 401. When the preform 400 rises, the support ring 401 is blocked by the pressure plate 7, while the preform insertion head 211 continues to move upward, realizing mechanical forced preform removal.

[0039] In this embodiment, a support ring 401 is provided on the outer periphery of the preform 400. The support ring 401 is designed to be precisely blocked by the pressure plate 7 to ensure the success rate of preform removal.

[0040] The adjustable automatic preform removal and de-preg blowing machine of this embodiment has the following beneficial technical effects: by changing the de-preg method to mechanical de-preg, the pressure plate 7 of the de-preg device 300 forcibly clamps the preform 400 support ring 401, eliminating the risk of preform slippage and achieving high-stability de-preg removal; through the adjustable pressure plate 7 and adaptive de-preg grippers, it is compatible with preforms of multiple specifications 400, improving the applicability of the blowing machine; through the coordination of the conveying device 100, the de-preg device 200, and the de-preg device 300, the de-preg removal actions are precisely linked, improving production efficiency.

[0041] In this embodiment, the mounting head 2 includes a blank holder 21, a rotating shaft 22, a rotating gear 23, a washer 24, a spacer ring 25, a first bearing component 26, a first pad 27, a spring 28, a second pad 29, a second bearing component 210, a blank insert head 211, and a blank insert pad 212. The blank holder 21 forms a mounting cavity 213, and the rotating shaft 22 is mounted in the mounting cavity 213. The rotating shaft 22 includes a narrow diameter section 221 and a wide diameter section 222, which form a limiting step 223. The rotating gear 23 and the washer 24 are mounted on the limiting step 223 from top to bottom. The spacer ring 25, the first bearing component 26, the first pad 27, the spring 28, the second pad 29, and the second bearing component 210 are sequentially mounted outside the wide diameter section 222 from top to bottom. The blank insert head 211 is mounted at the bottom end of the rotating shaft 22. The preform inserter 211 is fixed to the bottom end of the rotating shaft 22 by bolts. The preform inserter 211 is used to install the preform 400. The outer wall of the preform inserter 211 abuts against the inner wall of the preform 400's teeth, so that the preform 400 and the preform inserter 211 fit tightly together. The preform inserter pad 212 is installed on the preform inserter 211, and the preform inserter pad 212 serves to limit the position of the preform 400.

[0042] Preferably, the first bearing component 26 and the second bearing component 210 are ball bearings.

[0043] In this embodiment, the mounting head 2 further includes a first C-shaped retaining ring 214 and a second C-shaped retaining ring 215; the inner wall of the blank head seat 21 is also recessed with a first groove for mounting the first C-shaped retaining ring 214 and a second groove for mounting the second C-shaped retaining ring 215, the inner diameter of the first groove and the second groove being larger than the inner diameter of the mounting cavity 213; the top surface of the first bearing member 26 abuts against the bottom surface of the first C-shaped retaining ring 214, the bottom surface of the second bearing member 210 abuts against the top surface of the second C-shaped retaining ring 215, and the C-shaped retaining rings limit the movement to ensure the stable lifting and lowering of the rotating shaft 22.

[0044] In this embodiment, the inner wall of the blank holder 21 is further recessed with a third groove for installing the first bearing member 26 and a fourth groove for installing the second bearing member 210. The inner diameter of the third groove and the fourth groove is larger than the inner diameter of the mounting cavity 213 and smaller than the inner diameter of the first groove and the second groove.

[0045] In this embodiment, a third C-shaped buckle 218 is also included. A fifth groove for mounting the third C-shaped buckle 218 is formed on the outer wall of the rotating shaft 22. The second pad 29 is mounted on the third C-shaped buckle 218.

[0046] In this embodiment, the upper part of the mounting head 2 is also threaded with an anti-loosening nut 216 for pressing the rotating gear 23. The anti-loosening nut 216 is threadedly locked with the rotating shaft 22, thereby enhancing the reliability of the rotating gear 23.

[0047] In this embodiment, the embryo head seat 21 is snapped onto the annular conveying assembly 1 via the connecting part 217.

[0048] When the preform pulling device 200 pulls the washer 24, the anti-loosening nut 216, the rotating gear 23, the washer 24, the rotating shaft 22, the second pad 29, the third C-shaped retaining ring 218, the preform insertion head 211, the preform head pad 212, and the preform 400 rise together. The second pad 29 compresses the spring 28, and the support ring 401 of the preform 400 is forcibly locked by the pressure plate 7, causing the preform 400 to separate from the preform insertion head 211 and fall off.

[0049] In this embodiment, the preform removal device 200 further includes a Z-shaped mounting platform 6; the drive assembly 5 includes a cylinder 51, a floating joint 52, and a preform removal plate 53; the cylinder 51 is fixedly mounted on the top of the Z-shaped mounting platform 6, and the output end of the cylinder 51 is connected to the preform removal plate 53 through the floating joint 52. When the mounting head 2 reaches the work position, the left clamp 3 and the right clamp 4 automatically clamp the washer 24 on the upper part of the mounting head 2 through a tension spring; then the cylinder 51 retracts, driving the preform removal plate 53 to rise, and the clamps synchronously lift the rotating shaft 22 of the mounting head 2 through the pull plate, causing the preform 400 to move upward.

[0050] In this embodiment, the left clamp 3 includes a first left clamping jaw 31 and a second left clamping jaw 32. The first left clamping jaw 31 is mounted to the first end of the drawing plate 53 via a first left rotating shaft 33, and the second left clamping jaw 32 is mounted to the second end of the drawing plate 53 via a second left rotating shaft. The right clamp 4 includes a first right clamping jaw 41 and a second right clamping jaw 42. The first right clamping jaw 41 is mounted to the first end of the drawing plate 53 via a first right rotating shaft 43, and the second right clamping jaw 42 is mounted to the second end of the drawing plate 53 via a second right rotating shaft. By adjusting the tightness of the first left rotating shaft 33, the second left rotating shaft, the first right rotating shaft 43, and the second right rotating shaft, the distance between the left clamp 3 and the right clamp 4 can be adjusted to accommodate washers 24 of different sizes. The first left clamping jaw 31 and the first right clamping jaw 41 are connected by a first tension spring 34, and the second left clamping jaw 32 and the second right clamping jaw 42 are connected by a second tension spring. The distance between the left clamp 3 and the right clamp 4 is adaptive to the size of the washer 24 by the tension spring. It also includes a first pull plate 36 and a second pull plate 44. The first pull plate 36 is fixedly installed on the lower part of the first left gripper 31 and the second left gripper 32, and the second pull plate 44 is fixedly installed on the lower part of the first right gripper 41 and the second right gripper 42. The first pull plate 36 forms a first step 361 for the washer 24 to abut against, and the second pull plate 44 forms a second step 441 for the washer 24 to abut against.

[0051] In this embodiment, a slider 531 is fixedly connected to one side of the blank-drawing plate 53, and a slide rail 61 that cooperates with the slider 531 is provided on the Z-shaped mounting platform 6. The combination of the slider 531 and the slide rail 61 ensures that the blank-drawing plate 53 moves vertically.

[0052] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
