Description

Technical Field

[0001] This invention belongs to the field of packaging machinery technology, and in particular relates to a bottle clamping device that can be quickly detached. Background Technology

[0002] In the production of bottled liquid products, plastic bottles need to be arranged in a suitable manner and independently transported to various packaging stations. At stations such as blow molding and filling, the bottles need to be accurately positioned during transport to complete processes such as shaping, filling, and sealing. Bottle neck clamping devices can accurately clamp the bottles and, in conjunction with the moving parts of the star wheel, facilitate the transport of the bottles, enabling their movement between multiple stations.

[0003] However, in practical applications, the bottle-clamping and conveying process is affected by the main control system, especially during the handover process between the upstream and downstream star wheel transmissions. If there is even a slight difference in the rotational rhythm of the two star wheels, it is highly likely that the bottle-clamping device will misalign, causing the entire system to crash. Therefore, many manufacturers use various methods to detect such misalignment and report it to the main control system to implement automated measures, such as speed reduction. However, in actual applications, due to the production speed, even with the installation of position detection devices and speed reduction after misalignment, the initial speed is still very high. Even if the main control system initiates a deceleration program, the equipment still needs several seconds to stop. During this period, severe crashes can still occur, resulting in significant equipment damage and prolonged interruptions to continuous production. Therefore, there is an urgent need to research a bottle-clamping device that can quickly detach to solve the above problems. Summary of the Invention

[0007] As a preferred embodiment of the present invention, a plurality of first bolts corresponding to threaded pins are vertically inserted into the upper surface of the mounting plate; the lower end of the first bolt is inserted into the upper end of the threaded pin; the lower surface of the nut of the first bolt is in contact with the upper surface of the mounting plate; the first bolt and the threaded pin are threadedly engaged.

[0008] As a preferred embodiment of the present invention, each of the two bottle clamps is vertically inserted with a pin; the pin is rotatably engaged with the bottle clamp; and the pin is fixedly inserted into the support plate.

[0009] As a preferred embodiment of the present invention, a limiting plate is horizontally provided below the supporting plate; the limiting plate is connected to the supporting plate by a second bolt; and the bottle clamp is disposed between the supporting plate and the limiting plate.

[0010] As a preferred embodiment of the present invention, protrusions are fixedly inserted into the lower surfaces of both bottle clamps; the two ends of the tension spring are respectively connected to the two protrusions.

[0011] As a preferred embodiment of the present invention, a plurality of L-shaped support rods are arranged along the annular direction below the edge of the mounting plate; a connecting block is inserted into the vertical section of the support rod; the connecting block is respectively connected to the mounting plate and the support rod by a pair of third bolts; the first magnetic locator is fixedly embedded in the upper surface of the horizontal section of the support rod; the second magnetic locator is fixedly embedded in the lower surface of the limiting plate.

[0012] As a preferred embodiment of the present invention, the first magnetic locator is fixedly embedded in the lower surface of the mounting plate; the second magnetic locator is fixedly embedded in the upper surface of the support plate.

[0013] The present invention has the following beneficial effects:

[0014] This invention utilizes the lever principle to achieve normal bottle clamping and rotating conveying function.

It is designed with a closed-loop detection system to stop the main unit. Moreover, thanks to the quick installation design, it enables rapid replacement, quick troubleshooting, and resumption of production.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Example 1:

[0031] Please see Figure 1-5 As shown, this invention is a bottle clamping device that can be quickly detached, including a vertically arranged drive shaft 1, a mounting plate 2 horizontally fixed to the upper end of the drive shaft 1, and a proximity switch 3 vertically mounted on the edge of the mounting plate 2; the drive shaft 1 is used to transmit power to realize the horizontal rotation of the mounting plate 2; the proximity switch 3 is a conventional device in the art; multiple conventional first magnetic locators 4 are evenly distributed and fixed along the annular direction at the edge of the mounting plate 2; multiple support plates 5 are horizontally arranged along the annular direction below the edge of the mounting plate 2; the upper surface of each of the multiple support plates 5 is vertically provided with a receiving hole 501; a threaded pin 6 is threaded into the receiving hole 501; the threaded pin 6 is threaded into the receiving hole 501. The upper end of the pin 6 is fixed to the mounting plate 2; the upper surfaces of multiple support plates 5 are each vertically fixed with a detection rod 7 corresponding to the proximity switch 3; multiple support plates 5 are each fixed with a second magnetic positioner 8 corresponding to the first magnetic positioner 4; the second magnetic positioner 8 is a conventional device in the art; the magnetic properties between the inner surfaces of the second magnetic positioner 8 and the first magnetic positioner 4 are different; a pair of horizontally arranged bottle clamps 9 are rotatably connected to the lower surface of the support plate 5; the inner sides of the two bottle clamps 9 each have an arc-shaped notch 901; a clamping space for the bottle neck is formed between the two notches 901; the two bottle clamps 9 are connected by a tension spring 10.

[0032] It should be noted that, as Figure 3-4As shown, multiple L-shaped support rods 16 are arranged along the annular direction below the edge of the mounting plate 2; connecting blocks 17 are inserted into the vertical sections of the support rods 16; the connecting blocks 17 are respectively connected to the mounting plate 2 and the support rods 16 by a pair of third bolts 18; the first magnetic locator 4 is fixedly embedded in the upper surface of the horizontal section of the support rod 16; the upper surface of the horizontal section of the support rod 16 slides and fits against the lower surface of the limiting plate 13, thereby providing a lifting effect for the limiting plate 13; the second magnetic locator 8 is fixedly embedded in the lower surface of the limiting plate 13.

[0033] The specific working principle is as follows:

[0034] 1) When misalignment occurs during the rotation of the mounting plate 2, the bottle clamp 9 is impacted. Under the impact force, the support plate 5 breaks free from the magnetic attraction between the lower second magnetic locator 8 and the first magnetic locator 4 and begins to rotate around the threaded pin 6. When the support plate 5 rotates to the position where it completely breaks free from the magnetic attraction between the lower second magnetic locator 8 and the first magnetic locator 4 and breaks free from the support position of the bearing rod 16, the support plate 5 slides off the threaded pin 6 under the action of gravity, avoiding more serious impact.

[0035] 2) When the bottle clamp 9 slips off, the phase rotates with the mounting plate 2 to the detection position of the proximity switch 3. At this time, the detection rod 7 has slipped off with the support plate 5 and cannot provide a monitoring point. The proximity switch 3 cannot detect the signal and feeds back to the system to stop abnormally, so as to avoid causing a larger impact.

[0036] 3) When an abnormal shutdown is detected, maintenance and inspection are required to eliminate the cause of the impact. Replace the bottle clamp mechanism formed by the bottle clamp 9 and support plate 5, and offset the positions of the second magnetic locator 8 and the first magnetic locator 4. Align the receiving hole 501 on the support plate 5 with the threaded pin 6 at the installation phase, insert it, and rotate the support plate 5 to ensure that the second magnetic locator 8 is directly above the first magnetic locator 4 and achieve the attraction between the second magnetic locator 8 and the first magnetic locator 4. In this way, the positioning and installation of the bottle clamp 9 can be completed quickly.

[0037] Among them, such as Figure 3As shown, multiple first bolts 11 corresponding to threaded pins 6 are vertically inserted into the upper surface of the mounting plate 2; the lower end of the first bolt 11 is inserted into the upper end of the threaded pin 6; the lower surface of the nut of the first bolt 11 is in contact with the upper surface of the mounting plate 2; the bolt 11 and the mounting plate 2 are clearance-fitted; the first bolt 11 and the threaded pin 6 are threadedly fitted; the threaded pin 6 and the mounting plate 2 are interference-fitted. By designing multiple first bolts 11 corresponding to threaded pins 6 to be vertically inserted into the upper surface of the mounting plate 2, with the lower end of the first bolt 11 inserted into the upper end of the threaded pin 6, and ensuring that the lower surface of the nut of the first bolt 11 is in contact with the upper surface of the mounting plate 2 and that the first bolt 11 and the threaded pin 6 are threadedly fitted, the installation stability of the threaded pin 6 can be effectively improved.

[0038] Among them, such as Figure 3-4 and Figure 6 As shown, each of the two bottle clamps 9 has a vertically inserted pin 12; the pin 12 is rotatably engaged with the bottle clamp 9; the pin 12 is welded to the support plate 5; a limiting plate 13 is horizontally installed below the support plate 5; the limiting plate 13 is connected to the support plate 5 by a second bolt 14; the bottle clamp 9 is positioned between the support plate 5 and the limiting plate 13; protrusions 15 are fixedly inserted into the lower surfaces of both bottle clamps 9; the two ends of the tension spring 10 are respectively connected to the two protrusions 15. By horizontally installing the limiting plate 13 below the support plate 5, and connecting the limiting plate 13 to the support plate 5 by the second bolt 14, and positioning the bottle clamp 9 between the support plate 5 and the limiting plate 13, the stability of the bottle clamp 9 in use can be effectively guaranteed.

[0039] It should be further explained that, in this embodiment, the first magnetic locator 4 is designed to be fixedly embedded in the upper surface of the horizontal section of the bearing rod 16, and the upper surface of the horizontal section of the bearing rod 16 slides and fits against the lower surface of the limiting plate 13, so it can lift the bottle clamp 9. Therefore, this embodiment is more suitable for use when the bottle is full, lifting to overcome gravity and ensuring the transfer effect of the bottle.

[0040] Example 2:

[0041] The difference between this embodiment and Embodiment 1 lies in the installation positions of the first magnetic locator 4 and the second magnetic locator 8, which differ from those in Embodiment 1. Figure 7-10 As shown, the first magnetic locator 4 is fixedly embedded in the lower surface of the mounting plate 2; the second magnetic locator 8 is fixedly embedded in the upper surface of the support plate 5.

[0042] The specific working principle is as follows:

[0043] 1) When the installation plate 2 is misaligned during rotation, the bottle clamp 9 is impacted. Under the impact force, the support plate 5 breaks free from the magnetic attraction between the second magnetic locator 8 and the first magnetic locator 4 and begins to rotate around the threaded pin 6. When the support plate 5 rotates to the position where it is completely free from the magnetic attraction between the second magnetic locator 8 and the first magnetic locator 4, the support plate 5 slides off the threaded pin 6 under the action of gravity, avoiding more serious impact.

[0044] 2) When the bottle clamp 9 slips off, the phase rotates with the mounting plate 2 to the detection position of the proximity switch 3. At this time, the detection rod 7 has slipped off with the support plate 5 and cannot provide a monitoring point. The proximity switch 3 cannot detect the signal and feeds back to the system to stop abnormally, so as to avoid causing a larger impact.

[0045] 3) When an abnormal shutdown is detected, maintenance and inspection are required to eliminate the cause of the impact. Replace the bottle clamp mechanism formed by the bottle clamp 9 and support plate 5, align the receiving hole 501 on the support plate 5 with the threaded pin 6 at the installation phase, insert it and rotate the support plate 5 to ensure that the second magnetic positioner 8 is directly above the first magnetic positioner 4, and achieve the attraction between the second magnetic positioner 8 and the first magnetic positioner 4. In this way, the positioning and installation of the bottle clamp 9 can be completed quickly.

[0046] It should be further noted that, compared to Example 1, this example is more suitable for use when the bottle is empty.

[0047] The preferred embodiments of the present invention disclosed above are merely illustrative of the invention. These preferred embodiments do not exhaustively describe all details, nor do they limit the invention to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the invention, thereby enabling those skilled in the art to better understand and utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
