Description

Technical Field

[0001] The invention relates to the technical field of filling auxiliary equipment, and in particular to a plugging device suitable for softening an inner plug. Background Art

[0002] The inner plugs of cosmetic containers made of LDPE or PVC materials have higher hardness and can be assembled by the traditional inner plug pressing method - align the bottom of the inner plug with the container mouth, and use a press to push the top of the inner plug vertically downward to squeeze the inner plug into the container.

[0003] However, the inner plug made of DPE or PVC material has poor oil resistance and plasticity, while some cosmetics require the inner plug to have high oil resistance and plasticity, so it is necessary to use materials with high oil resistance and plasticity to make the inner plug, such as NBR materials. The inner plug made of such materials has high plasticity and will undergo large deformation under pressure, and the outer diameter of the inner plug is larger than the inner diameter of the container port. Therefore, it is impossible to use a press to directly push the soft inner plug into the container, that is, the traditional inner plug pressing device cannot complete the assembly of the soft inner plug. Therefore, the soft inner plug is now assembled manually - manually folding the soft inner plug, inserting the folded soft inner plug into the container port, allowing the soft inner plug to unfold naturally, and then using fine stainless steel nails to adjust the position of the soft inner plug to meet the assembly requirements. However, the manual assembly of soft inner plugs is limited by manpower, and the assembly efficiency is low, which cannot meet production needs. Summary of the invention

[0042] It can be seen from the above technical solutions that the present invention has the following advantages:

[0043] ① Under the guidance of the guide, the sliding part is slid away from the accommodating part, leaving enough space between the accommodating part and the sliding part, so that the container is placed in the second accommodating groove, and then the sliding part is slid close to the accommodating part, so that the port of the container contacts the sliding part in a manner aligned with the first through hole, and then the soft inner plug is placed into the first accommodating groove with the bottom end facing inward, so that the bottom end of the soft inner plug is in the intersection area of ​​the first accommodating groove and the first through hole, and then the driving part drives the plug pressing rod to be inserted into the first through hole under the guidance of the guide, so that the plug pressing rod contacts the bottom end of the soft inner plug, which is squeezed and bent, so that the protrusion on the bottom end of the soft inner plug is in the through hole direction of the first through hole. The plug rod forms a stable contact, and the plug rod is continuously inserted, thereby pushing the bottom end of the soft plug forward in the first through hole, and then pulling the soft plug as a whole from the first accommodating groove into the first through hole. Because the aperture of the first through hole is smaller than the outer diameter of the soft plug, the soft plug always moves toward the port in the first through hole in a folded state under the extrusion and pushing action of the plug rod in cooperation with the limit of the first through hole, and finally enters the port aligned with the first through hole as a whole. Finally, the plug rod is driven by the driving member to gradually withdraw from the port. The good plasticity of the soft plug allows itself to gradually restore its original volume as the plug rod withdraws, forming an interference fit with the port, and completing the assembly of the soft plug. By utilizing the good plasticity of the soft rubber plug itself, the driving member is set to drive the plug rod and cooperate with the limit of the first through hole to drag the soft plug into the container port. Under the automatic resetting of the soft rubber plug, the assembly of the soft rubber plug is completed. Compared with the original manual assembly, the assembly process is simplified, the assembly difficulty is reduced, the manual workload is reduced, and the assembly efficiency is improved.

[0044] ② By providing a plurality of plug pressing rods and correspondingly providing a plurality of first accommodating grooves, first through holes and second accommodating grooves, the driving member can be driven once and a plurality of soft inner plugs can be assembled at the same time, thereby further improving the assembly efficiency.

However, the manual assembly of soft inner plugs is limited by manpower, resulting in low assembly efficiency and unable to meet production needs.

[0062] It should be noted that: the sliding portion 100 needs to have enough space to open the first through hole 120 and the first accommodating groove 110 that intersect vertically, and the side close to the accommodating member 310 is adapted to the end face of the port 610 of the container 600 to ensure that the port 610 of the container 600 can be aligned and contacted with the first through hole 120. Here, its shape is not specifically limited, and it can be a cube, a rectangular parallelepiped, etc.; the driving member needs to have a linear driving function and can fix the plug rod 220 in a position aligned with the first through hole 120. It is not specifically limited here, and it can be an electric push rod, an electric cylinder, a pneumatic strut, a linear motor, etc.; the radial cross-sectional area of ​​the plug rod 220 needs to be smaller than the orifice area of ​​the first through hole 120 to ensure that the plug rod 220 can enter the first through hole 120 together with the plug; the accommodating member 310 only needs to have space for opening the second accommodating groove 311. Here, its shape is not specifically limited. The second accommodating groove 311 is adapted to the container 600 to ensure that after the container 600 is placed in the second accommodating groove 311, the port 610 of the container 600 is aligned with the first through hole 120, and the port 610 of the container 600 needs to be exposed so that the port 610 can contact the sliding part 100; the guide member 320 can guide the driving member and the sliding part 100 to move in the through hole direction of the first through hole 120, and its shape is adapted to the sliding connection position on the sliding part 100 and the driving member; the plug rod 220 is aligned with the first through hole 120, that is, the axis of the plug rod 220 is colinear with the axis of the first through hole 120; the shape and size of the port 610 of the container 600 is equal to the shape and size of the orifice of the first through hole 120, and the port 610 of the container 600 is aligned with the first through hole 120, that is, the center of the port 610 is in the axis direction of the first through hole 120.

[0063] Specifically, in order to enable the plunger rod 220 to form a stable abutment with the protrusion at the bottom end of the soft inner plug 500, so as to ensure that the soft inner plug 500 will be driven by the plunger rod 220 to move toward the port 610 of the container 600 during the process of inserting the plunger rod 220 into the first through hole 120, a notch 221 adapted to the soft inner plug 500 is provided at one end of the plunger rod 220 close to the sliding portion 100. In this embodiment, in order to simultaneously fix multiple plunger rods, a positioning plate is added to the driving member so that the driving member has enough space to install and fix the plunger rod 220, that is, the driving member is composed of a linear motor (not shown in the figure) and a positioning plate 211, the center of the upper surface of the positioning plate 211 is connected to the end of the driving shaft of the linear motor, and the positioning plate 211 is provided with a row of sixth through holes 211.1 distributed at equal intervals for fixing the plunger rod 220, and the sixth through hole 211.1 is vertically penetrated through the upper and lower surfaces of the positioning plate 211. The left and right ends of the positioning plate 211 are provided with two seventh through holes 211.2 which are compatible with the guide piece 320. The seventh through hole 211.2 is a circular through hole which vertically passes through the upper and lower surfaces of the positioning plate 211. The sixth through hole 211.1 is embedded with a cylindrical first copper sleeve 212. The plug rod 220 adopts a pin, the upper end of which is accommodated in the sixth through hole 211.1 of the positioning plate 211 to realize the fixed connection between the pin and the positioning plate 211. A semicircular notch 221 is provided at the lower end of the pin. In this embodiment, an example of assembling a circular soft inner plug 500 having a circle of protrusions at both the bottom and the top into a circular bottle is used for explanation, wherein the port 610 of the circular bottle is a straight tube structure having a diameter smaller than that of the cylindrical bottle body 620, and the length of the port 610 is equal to the distance between the protrusions at both ends of the soft inner plug 500. Therefore, a semicircular notch 221 having a diameter smaller than the outer diameter of the soft inner plug 500 is provided to fork the soft inner plug 500, and then the protrusion at the bottom end of the soft inner plug 500 forms a block to the lower end of the plug rod 220 to prevent the plug rod 220 from sliding out of the soft inner plug 500, so that the plug rod 220 and the soft inner plug 500 form a stable abutment, so that the plug rod 220 can drive the soft inner plug 500 to move toward the port 610 of the container 600.

[0064] Specifically, in order to stably fix the guide member 320 around the accommodating member 310 and make the base 300 have a certain degree of versatility, a bottom plate 330 and M second limiting blocks 340 are added to the base 300, where M is an integer greater than or equal to 2; the bottom plate 330 is provided with a fifth through hole 331; the bottom plate 330 is detachably connected to the second limiting block 340 through the fifth through hole 331; the bottom plate 330 is connected to one end of the guide member 320; and the M second limiting blocks 340 limit the accommodating member 310. The fifth through hole 331 is designed as a threaded through hole, and a plurality of evenly distributed threaded through holes are provided on the bottom plate 330, and the second limiting blocks 340 are locked with screws, so that the accommodating members 310 of different shapes can be limited by connecting the second limiting blocks 340 with threaded through holes at different positions, so that the bottom plate 330 can be matched with accommodating members 310 of different shapes. In the present embodiment, the accommodating part 310 is a rectangular parallelepiped structure, and a row of circular holes distributed at equal intervals are provided on its upper surface, namely, the second accommodating groove 311, the inner diameter of the circular hole is equal to the outer diameter of the bottle body 620, and the depth of the circular hole is approximately half of the height of the bottle body 620, the lower surface of the accommodating part 310 is in contact with the upper surface of the bottom plate 330, and a second limiting block 340 is in contact with the left, right and rear surfaces of the accommodating part 310; a total of three second limiting blocks 340 are provided, of which the two second limiting blocks 340 in contact with the left and right surfaces of the accommodating part 310 are heptahedrons of the same size and shape, and the second limiting block 340 in contact with the rear surface of the accommodating part 310 is a rectangular parallelepiped, and the second limiting blocks 340 are provided with first threaded through holes 341 for cooperating with screws and perpendicular to the upper surface of the bottom plate 330, the lower surface of the second limiting block 340 is in contact with the upper surface of the bottom plate 330, and the second limiting block 340 is in contact with the upper surface of the bottom plate 330 through the second limiting block 340 A threaded through hole cooperates with the threaded through hole and screws on the bottom plate 330 to be fixedly connected to the bottom plate 330, and the common limit of the three second limit blocks 340 locks the accommodating member 310 on the bottom plate 330; a threaded through hole penetrating the upper and lower surfaces of the bottom plate 330 is opened in the middle of the bottom plate 330, and the threaded through hole is a countersunk threaded circular hole, which is used to cooperate with the screw to lock the second limit block 340, that is, the fifth through hole 331, and second threaded through holes 332 penetrating the upper and lower surfaces of the bottom plate 330 are opened at the left and right ends of the bottom plate 330. The second threaded through hole 332 is a countersunk threaded circular hole, and its upper end aperture is adapted to the lower end of the guide member 320, that is, the upper and lower end apertures of the second threaded through hole 332 are equal, the middle aperture is smaller than the apertures at the two ends, and the middle hole wall is provided with an internal thread, and the guide member 320 is fixed to the bottom plate 330 in a manner perpendicular to the upper surface of the bottom plate 330 by cooperating with the screws.

[0065] Specifically, because the bottom of the first accommodating groove 110 needs to intersect with the first through hole 120 vertically, and the driving part moves in the vertical direction, the first accommodating groove 110 needs to be arranged horizontally, that is, it needs to be opened on the side of the sliding part 100. In order to open enough first accommodating grooves 110 on the sliding part 100 with limited volume and maximize the use of the sliding part 100 to improve assembly efficiency, N first through holes 120 are arranged in an array. For example, when the sliding part is a rectangular parallelepiped, a plurality of first through holes 120 arranged in an array can be opened on the outer edge of the upper surface of the rectangular parallelepiped, and the centers of the openings of the first through holes 120 on the upper surface are connected in sequence to form a rectangle similar to the upper surface, and corresponding first accommodating grooves are opened on the left, right, front and back surfaces of the rectangular parallelepiped. In this embodiment, the sliding portion 100 is composed of a rectangular parallelepiped and two sliding blocks 130, and the sliding blocks 130 are connected to the left and right surfaces of the rectangular parallelepiped; 12 circular through holes are opened on the rear side of the upper surface of the rectangular parallelepiped and vertically penetrate the upper and lower surfaces thereof, and the 12 circular through holes are evenly spaced and distributed in the length direction of the sliding portion 100, namely, the first through holes 120, and 12 circular blind holes corresponding to the 12 first through holes 120 are opened on the front surface of the rectangular parallelepiped, namely, the first accommodating grooves 110, and the bottom of the circular blind hole penetrates the hole wall of the first through hole 120, and the circular blind hole is perpendicular to the front surface of the rectangular parallelepiped, and the axis of the circular blind hole is aligned with the corresponding first through hole 120. The axial lines intersect vertically; the sliding block 130 is a rectangular parallelepiped structure, on which an eighth through hole 131 is provided, which vertically penetrates the upper and lower surfaces thereof and matches the guide member 320. In this embodiment, the guide member 320 is a round rod structure, so the eighth through hole 131 is set as a circular through hole. In order to reduce the wear of the sliding block 130 caused by the friction between the guide member 320 and the sliding block 130, a cylindrical second copper sleeve 140 is embedded in the eighth through hole 131, which is used to directly contact the guide member 320, and the sliding block 130 and the guide member 320 are isolated by the second copper sleeve 140. The wear resistance of the second copper sleeve 140 is utilized to improve the durability of the sliding block 130. The functions of the first copper sleeve 212 and the third copper sleeve 430 are the same as those of the second copper sleeve 140.

[0066] Specifically, the bottom of the bottle body 620 is fixed by the second accommodating groove 311 so that the port 610 is aligned with the first through hole 120. The port 610 may be offset due to the deformation of the bottle body 620 itself or the deviation of the manufacturing process, resulting in an alignment error between the port 610 and the first through hole 120, thereby affecting the assembly. In order to ensure that the port 610 can be accurately aligned with the first through hole 120, a positioning portion 400 is added; the positioning portion 400 is arranged between the sliding portion 100 and the accommodating member 310, and is aligned with the guide The guide 320 is slidably connected; the positioning portion 400 is provided with N second through holes 410; the second through holes 410 are aligned with the first through holes 120, and the second through holes 410 are stepped through holes; the aperture diameter of the first stage 411 of the second through holes 410 linearly decreases toward the second stage 412, and the minimum aperture diameter of the first stage 411 is equal to the outer diameter of the port 610; the aperture diameter of the second stage 412 is equal to the inner diameter of the port 610; the first stage 411 is close to the accommodating member 310, and the second stage 412 is close to the sliding portion 100. By setting the first stage 411 in the second through hole 410 so that the inner diameter linearly decreases to the second stage 412, and aligning with the port 610 through a larger aperture, the influence of the offset can be eliminated, ensuring that the port 610 must enter the second through hole 410, and then gradually guiding the port 610 into the second stage 412 through the linearly decreasing aperture to be precisely aligned with the first through hole 120, thereby avoiding the influence of the bottle body 620 itself on the assembly. At the same time, the second through hole 410 forms a certain locking on the port 610, which can avoid the influence of the shaking of the container 600 on the assembly. In this embodiment, the positioning portion 400 is a plate-like structure, and a ninth through hole 420 penetrating the upper and lower surfaces thereof and matching with the guide member 320 is provided at both left and right ends of the positioning portion 400. Since the guide member is a round rod, the ninth through hole 420 is a circular through hole, in which a cylindrical third copper sleeve 430 is embedded. A plurality of second through holes 410 penetrating the upper and lower surfaces thereof are provided in the middle portion of the positioning portion 400, and the second through holes 410 are arranged in a straight line at equal intervals; the second through holes 410 are circular holes, and the lower end thereof is a funnel-shaped hole section, and the aperture gradually decreases from bottom to top, namely the first stage 411, and the upper end thereof is a hole section with an aperture equal to the inner diameter of the port 610, namely the second stage 412, and the depth of the first stage 411 is much greater than the depth of the second stage 412.

[0067] Specifically, in order to further improve the efficiency of assembly, a first limit block 321 and a spring 322 are sleeved in the middle of the guide member 320; the first limit block 321 is arranged between the positioning portion 400 and the receiving portion 310; one end of the spring 322 is connected to the first limit block 321, and the other end is connected to the positioning portion 400. By utilizing the elasticity of the spring 322, the sliding portion 100 and the positioning portion 400 can automatically slide away from or close to the receiving portion 310. When the driving member drives the pressing member 230 to move downward, the pressing member 230 presses the soft inner plug 500 against each other, so that the pressing member 230 and the soft inner plug 500 both generate friction with the hole wall of the first through hole 120. The pressing member 230 and the soft inner plug 500 impart a downward friction force to the hole wall, and the friction force becomes the compression force of the spring 322, compressing the spring 322, thereby allowing the sliding portion 100 and the positioning portion 400 at the upper end of the spring 322 to move downward. The sliding part cooperates with the port 610, so that the port 610 is connected to the first through hole 120; when the soft inner plug 500 completely enters the port 610, the driving part drives the plugging part 230 to move upward, at this time, the downward friction force disappears, and under the driving of the return elastic force of the spring 322, the sliding part 100 and the positioning part 400 slide upward, and sufficient disassembly space is reserved for taking out the container 600 with the soft inner plug 500 from the second receiving groove 311, and sufficient assembly space is reserved for loading the container 600 to be assembled with the soft inner plug 500 into the second receiving groove 311. In this way, the steps of sliding the sliding part 100 and the positioning part 400 are omitted, and the assembly process is further simplified, that is, the assembly efficiency is further improved. In this embodiment, in order to limit the maximum compression amount of the spring 322, a spring seat 323 is sleeved in the middle of the guide 320. The spring seat 323 is a straight tube structure, and a circular plate is arranged inside the lower end thereof. The inner diameter of the circular plate is equal to the diameter of the guide 320, and the outer diameter of the circular plate is equal to the inner diameter of the straight tube structure. The upper surface of the circular plate supports the spring 322. When the lower surface of the positioning part 400 contacts the upper end of the spring seat 323, the spring seat 323 bears the downward friction force, the sliding part 100 and the positioning part 400 cannot continue to slide downward, and the spring 322 will no longer be compressed.

[0068] Specifically, the plugging member 230 sends the bottom protrusion of the soft inner plug 500 into the top area of ​​the bottle body 620, allowing the bottom protrusion to stretch, thereby being clamped at the junction of the port 610 and the bottle body 620, that is, the maximum distance that the plugging member 230 can move downward needs to be determined according to the height of the port 610. Because different containers 600 have ports 610 of different heights, different containers 600 have different requirements for the maximum distance of the downward movement of the plugging member 230. The socket position of the first limit block 321, the height of the spring seat 323, the height of the positioning portion 400 and the height of the sliding block 130 jointly determine the maximum distance that the plugging member 230 can move downward - when the positioning portion 400 contacts the upper end of the spring seat 323 and the positioning plate 211 contacts the sliding block 130, the plugging member 230 will not be able to move downward further. Therefore, when the height of the spring seat 323, the height of the positioning portion 400 and the height of the sliding block 130 cannot be easily changed, the sleeve position of the first limit block 321 can be adjusted to control the maximum distance that the pressing member 230 can move downward. In order to allow the sleeve position of the first limit block 321 to be adjusted as needed, a third through hole 321.1, a fourth through hole 321.2 and a through slot 321.3 are provided on the first limit block 321; the third through hole 321.1 is adapted to the guide member 320; the through slot 321.3 of the through slot 321.3 is in the same direction as the through hole direction of the third through hole 321.1, and the through slot 321.3 is connected to the third through hole 321.1; the fourth through hole 321.2 vertically penetrates the side wall of the through slot 321.3, the fourth through hole 321.2 is close to the notch of the through slot 321.3, and there is a gap between the fourth through hole 321.2 and the third through hole 321.1. 3, and the third through hole 321.1 is also connected to the guide member 320, thereby realizing that the first limit block 321 is fixedly connected to the guide member 320, and the first limit block 321 is fixedly connected to the guide member 320, and the third through hole 321.1 is connected to the guide member 320, and the third through hole 321.1 is connected to the guide member 320, so that the first limit block 321 is fixedly connected to the guide member 320, and the third through hole 321.1 is connected to the guide member 320, so that the first limit block 321 is fixedly connected to the guide member 320, and the third through hole 321 is connected to the guide member 320, so that the first limit block 321 is fixedly connected to the guide member 320, and the first limit block 321 is fixedly connected to the guide member 320, so that the installation position of the first limit block 321 can be quickly adjusted as needed.In this embodiment, the first limit block 321 is a rectangular structure, and the centers of its upper and lower surfaces are vertically penetrated by a circular through hole, which is compatible with the guide member 320, namely the third through hole 321.1; the front side of the third through hole 321.1 is provided with a gap that vertically penetrates the upper and lower surfaces of the first limit block 321, and the gap divides the front side of the first limit block 321 evenly into two parts, and the gap is the through groove 321.3; the front side of the first limit block 321 is provided with a circular through hole that vertically penetrates its left and right surfaces, and the circular through hole vertically penetrates the left and right avoidance of the through groove 321.3, namely the fourth through hole 321.2.

[0069] Optionally, when the pressing device is not provided with the positioning portion 400, a first stopper 321, a spring 322 and a spring seat 323 may also be sleeved in the middle of the guide member 320. In this case, the first stopper 321 is provided between the sliding portion 100 and the receiving member 310, the upper end of the spring 322 is connected to the sliding portion 100, the lower end of the spring 322 is connected to the upper surface of the annular plate in the spring seat 323, and the lower end of the spring seat 323 is connected to the upper surface of the first stopper 321. By utilizing the elasticity of the spring 322, the sliding portion 100 can automatically slide away from or close to the receiving member 310, thereby improving assembly efficiency.
