Description

Technical Field

[0001] This application relates to the field of punching equipment, and more particularly to a packaging bottle and a punching device thereof. Background Technology

[0002] Packaging bottles are a type of packaging container in the packaging industry. Packaging bottles are usually used to carry liquids. In the field of cosmetics, packaging bottles are usually equipped with a press-type pump head.

[0003] Currently, some packaging bottles have an inner liner and an outer shell. The outer shell provides strength to the packaging bottle, while the inner liner contracts with the contents to reduce air contact with the contents. There is a gap between the inner liner and the outer shell, requiring through holes to be made in the side wall of the outer shell to maintain the balance between the internal and external air pressure of the inner liner. Since the outer shell is cylindrical, the punching equipment is manually fed, making it difficult to ensure that the punching direction can penetrate the axial direction of the outer shell. This can lead to the punching equipment being unable to break through the outer shell, resulting in low punching quality for the packaging bottles. Summary of the Invention

[0004] In order to improve the punching quality of packaging bottles by punching equipment, this application provides a packaging bottle and punching equipment thereof.

[0005] In the first aspect, this application provides a punching device, which adopts the following technical solution:

[0006] A punching device includes a frame, a conveying assembly, a feeding assembly, and a punching assembly. The conveying assembly includes a conveyor motor, several conveyor rollers, a conveyor belt, and several push blocks. The several conveyor rollers are distributed along the direction from the feeding assembly to the punching assembly. The conveyor rollers are hourglass-shaped with diameters at both ends larger than their diameter in the middle. The conveyor belt is sleeved on the several conveyor rollers. The conveyor motor is used to drive the conveyor rollers to rotate. The several push blocks are distributed circumferentially along the conveyor belt and are disposed on the conveyor belt. The feeding assembly is used to place packaging bottles on the conveying assembly, and the punching assembly is used to punch holes in the packaging bottles on the conveyor belt.

[0007] By adopting the above technical solution, the feeding assembly is used to place the packaging bottles to be punched onto the conveying assembly. The conveying motor drives the conveying roller to move, and the conveying roller drives the conveyor belt to rotate. Since the conveying roller is an hourglass shape with large ends and a small middle, the horizontal packaging bottles will always be located at the lowest point of the conveyor belt, making each packaging bottle parallel to each other. This ensures that the axis of the punching drill bit passes through the axis of the packaging bottle, improving the punching quality of the impact equipment on the packaging bottles. The pushing block keeps the distance between each packaging bottle consistent, ensuring that the drilling interval of the punching assembly is consistent, and improving the positioning accuracy of the punching assembly.

[0008] Optionally, the feeding assembly includes a feeding bin and two step feeding sections. The feeding bin is located above the conveyor belt and is used to hold the packaging bottles to be punched. The lower end face of the feeding bin has a feeding port. The feeding assembly is distributed along the width direction of the conveyor belt. The feeding assembly includes a rotating rod, several limiting plates, and a driving component. The rotating rod is horizontally arranged and rotatably connected to the inner side wall of the feeding bin. Several limiting plates are distributed circumferentially along the axis of the rotating rod. The limiting plates are used to block the feeding port. The driving component is used to drive the rotating rod to rotate.

[0009] By adopting the above technical solution, the feeding bin is used to store unpunched packaging bottles. The unpunched packaging bottles are periodically fed onto the conveyor belt by the distributed feeding assembly. The drive component drives the rotating rod to rotate, and the rotating rod drives the limiting plate to rotate. The rotation of the limiting plate feeds the unpunched packaging bottles that are pressed against the limiting plate onto the conveyor belt. The adjacent limiting plates rotate with the rotating rod and block the feeding port, so that subsequent unpunched packaging bottles cannot leave the feeding bin from the feeding port. The feeding assembly has a simple structure and realizes the operation of periodically feeding packaging bottles.

[0010] Optionally, the frame is further provided with two positioning components for ensuring that the packaging bottle abuts against the push block. The positioning components are located between the feeding component and the punching component. The two positioning components are distributed along the width direction of the conveyor belt. Each positioning component includes a positioning plate and a torsion spring. The positioning plate is rotatably connected to the frame. The distance between the two positioning plates gradually decreases along the direction from the feeding component to the punching component. The torsion spring is sleeved on the rotation axis of the positioning plate. The torsion spring is used to bring the two positioning plates closer to each other at the end facing the punching component.

[0011] By adopting the above technical solution, the feeding component cannot guarantee that the packaging bottle will abut against the push block, and the distance between the packaging bottles cannot be guaranteed, which will cause deviation in the punching position of the subsequent punching component. The positioning component is used to ensure that the packaging bottle remains abut against the push block. When the packaging bottle is on the conveyor belt and runs to the position of the positioning component, the diameter of the packaging bottle is greater than the minimum distance between the two positioning plates. The friction between the packaging bottle and the conveyor belt is not enough for the packaging bottle to push the positioning plates away until the push block abuts against the packaging bottle. Under the action of the push block, the packaging bottle will push the two positioning plates away from each other against the torsion spring until the distance between the two positioning plates is enough for the packaging bottle to pass through. At this time, it is ensured that the packaging bottle abuts against the push block, and the distance between the subsequent packaging bottles remains consistent. The positioning component ensures that the packaging bottle is in a consistent punching position in the punching component.

[0012] Optionally, the two driving components correspond one-to-one with the two positioning components. Each driving component includes a ratchet, a pawl, a mounting wheel, a clamping spring, a first bevel gear, and a second bevel gear. The mounting wheel is coaxially arranged with the rotating rod and is located at one end of the rotating rod. The ratchet is coaxially arranged with the rotating rod and is rotatably connected to the outer wall of the discharge bin. The pawl is rotatably connected to the mounting wheel. The clamping spring is used to keep the pawl engaged with the ratchet. The first bevel gear is coaxially arranged with the ratchet and is located at one end of the ratchet. The second bevel gear is coaxially arranged with the rotation axis of the positioning plate on the same side and is located on the rotation axis of the positioning plate. The first bevel gear meshes with the second bevel gear.

[0013] By adopting the above technical solution, during the process of the push block moving the packaging bottle toward the positioning component, the packaging bottle overcomes the elastic force of the torsion spring and drives the positioning plate to rotate. The rotation of the positioning plate drives the second bevel gear to rotate, the second bevel gear drives the first bevel gear to rotate, and the first bevel gear drives the ratchet to rotate. At this time, the pawl disengages from the ratchet, and the ratchet rotates relative to the mounting wheel. At this time, the rotating rod remains stationary, and the sealing plate remains in the state of sealing the discharge port. When the push block drives the packaging bottle away from the positioning component, the positioning plate returns under the action of the torsion spring and rotates in the opposite direction. The positioning plate drives the second bevel gear to rotate, the second bevel gear drives the first bevel gear to rotate, and the first bevel gear drives the ratchet to rotate. The pawl engages with the ratchet under the action of the clamping spring, and the mounting wheel rotates with the ratchet. The rotation of the mounting wheel drives the rotating rod to rotate, and the rotating rod drives the sealing plate to rotate. The perforated packaging bottle that abuts against the sealing plate is placed onto the conveyor belt, and the adjacent sealing plate seals the sealing opening. Through the drive component, subsequent packaging bottles are sequentially placed onto the conveyor belt during the positioning process without human intervention.

[0014] Optionally, the frame is further provided with two clamping assemblies for reducing the detachment of the packaging bottle from the conveyor belt during punching. The clamping assemblies are located between the conveying assembly and the punching assembly. The two clamping assemblies are distributed along the width direction of the conveyor belt. Each clamping assembly includes a clamping strip and several clamping springs. The length direction of the clamping strip is parallel to the length direction of the conveyor belt. The distance between the two clamping strips gradually decreases along the direction from the conveyor belt to the punching assembly. The clamping strip is slidably connected to the frame along the width direction of the conveyor belt. The several clamping springs are distributed along the length direction of the clamping strip. The clamping springs are used for the clamping strip to abut against the packaging bottle.

[0015] By adopting the above technical solution, since punching holes in the packaging bottle will cause uneven force on the bottle, the bottle will detach from the conveyor belt, and the punching quality will be greatly reduced. The clamping component can keep the bottle pressed against the conveyor belt. The clamping strip moves along the width of the conveyor belt, and the clamping spring is used to press the clamping strip against the bottle. The distance between the two clamping strips gradually decreases along the direction from the conveyor belt to the punching component. The clamping strip guides the bottle to stay pressed against the conveyor belt. The quality of punching the packaging bottle is improved by the clamping component.

[0016] Optionally, the clamping assembly further includes a guide bar, one end of which is disposed at the end of the clamping bar facing the feeding assembly, and the distance between the two guide bars gradually decreases along the direction from the feeding assembly to the punching assembly.

[0017] By adopting the above technical solution, since the clamping strips will be close to each other, it is not easy for the bottle to enter directly between the clamping strips. Forcing entry will scratch the outside of the bottle and reduce the quality of the bottle. The two guide strips are flared, which makes it easier for the bottle to enter between the two clamping strips and reduces the quality problems on the outside of the bottle.

[0018] Optionally, the punching assembly includes a punching motor, a punching drill bit, and a driving component. The punching motor is mounted on the frame, the punching drill bit is mounted on the output shaft of the punching motor, and the driving component is used to drive the punching motor to move toward the packaging bottle.

[0019] By adopting the above technical solution, the punching motor drives the punching drill bit to rotate, and the driving component drives the punching drill bit to move towards the packaging bottle. The punching drill bit drills through holes in the bottle body. The punching assembly has a simple structure and is easy for workers to operate.

[0020] Optionally, the punching assembly further includes a synchronizing element, which includes a timing belt, two first timing pulleys, two second timing pulleys, a sliding block, a mounting block, and a synchronizing block. The two first timing pulleys are distributed along the direction of the conveyor belt and are rotatably connected to the frame. The two second timing pulleys are located below the first timing pulleys and are sequentially lowered along the direction from the feeding assembly to the punching assembly. The second timing pulleys are rotatably connected to the frame. The timing belt is sleeved on the two first timing pulleys and the two second timing pulleys. The synchronizing block is disposed on the timing belt. The mounting block is slidably connected to the frame along the conveying direction of the conveying assembly. The mounting block is slidably connected to the mounting block in the vertical direction and rotatably connected to the synchronizing block in the horizontal direction. The punching motor is disposed on the mounting block.

[0021] By adopting the above technical solution, the sliding block moves along the length of the conveyor belt, the mounting block slides vertically on the sliding block, and the punching motor is set on the mounting block, enabling the punching motor to perform multiple movements on the plane. The mounting block is set on the synchronization block, which is set on the synchronization belt, enabling the mounting block to move along the path of the synchronization belt. The synchronization belt is sleeved on two first synchronization pulleys and two second synchronization pulleys, forming a quadrilateral. The synchronization belt located between the two second synchronization pulleys will drive the synchronization block to gradually approach the conveyor belt, and the moving speed of the block along the conveyor belt direction is the same as the moving speed of the conveyor belt. Relative to the conveyor belt, the synchronization block moves vertically downward. At this time, the punching motor drives the punching head to move towards the packaging bottle until the packaging bottle is punched. Afterward, the synchronization block will drive the mounting block to move away from the synchronization belt, and the punching drill bit will move away from the packaging bottle. Then, the synchronization block will drive the mounting block to return to the initial position to punch subsequent packaging bottles. During the punching process, the punching drill bit moves vertically relative to the packaging bottle, so that the conveyor belt does not need to stop running, thus improving work efficiency.

[0022] Optionally, the driving component includes a driving gear, an idler wheel, a first driving wheel, a second driving wheel, and a driving timing belt. The driving gear is disposed on the conveyor roller. The idler wheel is rotatably connected to the frame and meshes with the driving gear. The first driving wheel is coaxially disposed with the idler wheel and is located on the rotation axis of the idler wheel. The second driving wheel is coaxially disposed with one of the second timing wheels and is located on the rotation axis of the second timing wheel. The driving timing belt is sleeved on the first driving wheel and the second driving wheel.

[0023] By adopting the above technical solution, the conveyor roller drives the drive gear to rotate, the drive gear drives the idler wheel to rotate, the idler wheel drives the first drive wheel to rotate, the first drive wheel drives the second drive wheel to rotate via the drive timing belt, the second drive wheel drives the second drive wheel to rotate, the second drive wheel drives the timing belt to rotate, and the timing belt can drive the punching drill bit to move. The drive component hooks the timing component with the conveyor assembly, so that the moving speed of the punching drill bit along the conveyor belt direction is consistent with the moving speed of the conveyor belt, thereby improving the punching quality of the packaging bottle.

[0024] Secondly, the packaging bottle provided in this application adopts the following technical solution:

[0025] A packaging bottle includes a bottle body and an inner liner. The inner liner is made of a soft material and is used to hold and contain items. The inner liner is disposed within the bottle body, and there is a cavity between the bottle body and the inner liner. The bottle body is used for threaded connection with a vacuum pump head, and the inner liner is used to form a sealed space with the vacuum pump head. A through hole communicating with the cavity is provided on the side wall of the bottle body, and the through hole is processed using the aforementioned punching equipment.

[0026] By adopting the above technical solution, the vacuum pump head and the inner liner form a sealed space. When the user needs to use the contents of the inner liner, the contents are squeezed out of the inner liner by squeezing the vacuum pump head. Since air cannot enter the inner liner through the vacuum pump head, the inner liner contracts, and air enters the cavity through the through hole of the bottle body, maintaining the air pressure balance between the inner liner and the outside. The bottle body provides the strength and aesthetics of the packaging bottle, and the inner liner reduces the contact between the contents and the outside air, delaying the oxidation of the contents.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] The funnel-shaped conveyor belt ensures that the horizontally placed packaging bottles are always at the lowest point of the conveyor belt, ensuring that the punching drill bit is parallel to the radial direction of the packaging bottle.

[0029] The positioning component is used to abut the packaging bottle against the push block, so that the distance between subsequent packaging bottles is the same, and to control the punching position of the packaging bottle;

[0030] The drive component enables the positioning component and the feeding component to work together. When a bottle comes off the positioning component, the feeding component can put the unpunched bottle onto the conveyor belt, reducing the workload of the workers.

[0031] The clamping assembly is used to prevent the packaging bottle from detaching from the conveyor belt due to uneven force on the packaging bottle during the punching assembly, thus improving the quality of the packaging bottle punching.

[0032] The synchronizing element ensures that the punch head moves relative to the conveyor belt during the punching process, enabling the punching drill to move vertically downward relative to the packaging bottle without stopping the conveyor belt during punching, thus improving the working efficiency of the punching equipment.

The driving timing belt 535 is sleeved on the first driving wheel 533 and the second driving wheel 534.

[0050] The implementation principle of a punching device according to an embodiment of this application is as follows: The packaging bottle passes through the feeding component 4, the positioning component 6, the pressing component 8 and the punching component 5 in sequence in the punching device. The packaging bottle to be processed is placed in the feeding bin 41. The feeding component is used to control the packaging bottle to be fed into the feeding bin 41 in sequence. The packaging bottle will first go to the positioning component 6 on the conveyor belt 33. The positioning plate 61 will block the packaging bottle, so that the packaging bottle moves relative to the conveyor belt 33 until the packaging bottle abuts the pushing block 34. The pushing block 34 drives the packaging bottle to move, and drives the positioning plate 61 to overcome the elastic force of the torsion spring 62. The positioning plate 61 rotates. The packaging bottle passes through the positioning component 6. The positioning plate 61 is reset under the action of the torsion spring 62 until it abuts the limiting post 63.

[0051] When the packaging bottle causes the positioning plate 61 to rotate, the positioning plate 61 drives the second bevel gear 76 to rotate, the second bevel gear 76 drives the first bevel gear 75 to rotate, and the first bevel gear 75 drives the ratchet 71 to rotate. At this time, the pawl 72 cannot engage the ratchet 71, and the ratchet 71 rotates relative to the mounting wheel 73. The limiting plate 422 keeps the discharge port 411 blocked. After the packaging bottle moves away from the positioning plate 61, the positioning plate 61 returns to its original position. The positioning plate 61 drives the second bevel gear 76 to rotate, the second bevel gear 76 drives the first bevel gear 75 to rotate, and the first bevel gear 75 drives the ratchet 71 to rotate. At this time, the pawl 72 is kept in contact with the ratchet 71 under the action of the clamping spring 74. The mounting wheel 73 rotates with the ratchet 71, and the mounting wheel 73 drives the rotating rod 421 to rotate. The limiting plate 422, which originally blocked the discharge port 411, rotates and puts the packaging bottle to be processed onto the conveyor belt 33. The adjacent sealing plate blocks the discharge port 411, and the above operation is repeated.

[0052] When the bottle is between the two clamping components 8, it is guided by the guide bar 83 into the space between the two clamping bars 81. The clamping bars 81, under the action of the clamping spring 82, hold the bottle against the conveyor belt 33, ensuring the bottle's position is fixed and facilitating the punching component 5 to punch the bottle. When the bottle moves below the punching component 5, the synchronizing block 546 moves to the hypotenuse of the right-angled trapezoidal synchronous belt 541. Under the combined action of the sliding block 544 and the mounting block 545, the punching drill bit 52 and the conveyor belt 33 maintain the same speed in the horizontal direction. The punching head gradually approaches the bottle, and the punching motor 51 keeps the punching drill bit 52 rotating to drill the bottle. After the bottle is drilled, the synchronizing block 546 drives the sliding block 544 to move vertically upward, facilitating the bottle to disengage from the punching drill bit 52. The synchronizing block 546 returns to its initial position as the synchronous belt 541 continues to move.

[0053] The synchronous belt 541 is controlled by the drive component 53. The conveyor roller 32 drives the drive gear 531 to rotate, the drive gear 531 drives the idler wheel 532 to rotate, the idler wheel 532 drives the first drive wheel 533 to rotate, the first drive wheel 533 drives the second drive wheel 534 to rotate through the drive synchronous belt 535, the second drive wheel 534 drives the second synchronous wheel 543 to rotate, and the second synchronous wheel 543 drives the synchronous belt 541 to move. This achieves speed coordination between the conveyor belt 33 and the synchronous belt 541, and allows the packaging bottle punching to be done without stopping the conveyor belt 33, thus improving the working efficiency of the punching equipment.

[0054] This application also discloses a packaging bottle.

[0055] Reference Figure 7 A packaging bottle includes a bottle body 11 and an inner liner 12. The bottle body 11 is cylindrical, and the diameter of the bottle mouth is smaller than the diameter of the bottle body 11. The bottle body 11 is connected to a vacuum pump head by a thread. The inner liner 12 is located inside the bottle body 11 and is disposed on the inner side wall of the bottle body 11. The inner liner 12 communicates with the bottle mouth and is used to hold the contents. The inner liner 12 forms a sealed space with the vacuum pump head. A cavity 13 is provided between the inner liner 12 and the bottle body 11. A through hole 14 is provided on the outer side wall of the bottle body 11 and communicates with the cavity 13. The through hole 14 is punched using the aforementioned punching equipment.

[0056] The implementation principle of a packaging bottle in this application embodiment is as follows: the user can pump out the contents in the inner liner 12 through the vacuum pump head. At this time, as the contents in the inner liner 12 decrease, the vacuum pump head prevents air from entering the inner liner 12, and the inner liner 12 contracts. At this time, the air enters the cavity 13 through the through hole 14, ensuring that the air pressure inside the inner liner 12 is consistent with the external air pressure. Air cannot enter the inner liner 12, reducing the oxidation rate of the contents.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
