Description

Technical Field

[0001] The utility model relates to sanitary products, in particular to production equipment for condoms. Background Art

[0002] Condoms are rubber products. During the production process, the condom mold is dipped in a pool of liquid rubber, and the liquid rubber adheres to the condom mold. The condom mold exits the liquid rubber pool, and after cooling, the rubber on it forms a condom prototype. After that, the condom prototype needs to be flanging. After that, the condom is separated from the mold through the demoulding process. The production of condoms is an assembly line operation, which requires a transmission mechanism to drive the condom mold through the liquid rubber pool, the flanging device, and the demoulding mechanism. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a flanging device for the production line of condoms.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a condom flanging assembly structure, comprising a conveying structure for conveying a condom mold, a first flanging roller and a second flanging roller arranged beside the conveying structure, and a mold self-rotation driving mechanism capable of driving the condom mold to rotate, the first flanging roller and the second flanging roller are arranged front and back along the conveying direction of the conveying structure, the first flanging roller and the second flanging roller are both arranged obliquely, the rear end of the first flanging roller is inclined outward, and the front end of the second flanging roller is inclined outward. That is, the first flanging roller and the second flanging roller are inclined in opposite directions.

[0005] The flanging device of the present invention is arranged beside the conveying structure, the mold self-rotation driving mechanism is installed on the top bracket, the top bracket is fixed on the ceiling, and the flanging roller is finally supported by the bottom bracket. In this way, the condom mold on the conveying structure can pass between the mold self-rotation driving mechanism and the flanging roller to realize the production line of condoms.

[0006] Under the drive of the transmission structure, the lying condom mold passes between the mold self-rotation drive mechanism and the flanging roller. The mold self-rotation drive mechanism acts on the upper part of the condom mold to make the condom mold rotate; the flanging roller acts on the lower part of the condom mold to flanging the condom prototype on the mold. In this way, the condom prototype on the mold is flanging during the self-rotation process, and a better flanging effect can be obtained.

[0007] The first flanging roller and the second flanging roller are arranged at an angle. Specifically, the condom molds conveyed by the conveying structure are a row of molds, each mold is formed with a condom prototype, and the flanging roller is inclined with respect to the row of molds. A specific mold, under the conveyance of the conveying structure, first contacts with the front end of the flanging roller, and the front end of the flanging roller acts on the rear half of the mold. When the mold moves to the rear end of the flanging roller, the rear end of the flanging roller acts on the front half of the mold. In this way, the self-rotating flanging roller can effectively flanging the condom prototype on the mold.

[0008] Under the transmission of the transmission structure, the mold first passes through the first flanging roller and then passes through the second flanging roller. Since the first flanging roller is inclined to the condom mold, the force of the first flanging roller on the condom prototype is inclined to the condom mold, and the force is inclined forward. In this way, the flanging condom is twisted on the mold due to the inclined force. In order to eliminate this distortion, the present invention sets a second flanging roller after the first flanging roller. The force of the second flanging roller on the condom on the mold is opposite to the force of the first flanging roller on the condom, so that the twisted condom is reset to ensure the quality of the condom.

[0009] The first flanging roller is equipped with a first mold self-rotation driving mechanism, and the second flanging roller is equipped with a second mold self-rotation driving mechanism; the first mold self-rotation driving mechanism and the second mold self-rotation driving mechanism are located above the mold, and the first flanging roller and the second flanging roller are located below the mold, and the first mold self-rotation driving mechanism is located between the conveying structure and the first flanging roller, and the second mold self-rotation driving mechanism is located between the conveying structure and the second flanging roller; any mold self-rotation driving mechanism includes a transmission belt and a follower wheel, and the follower wheel presses the transmission belt toward the mold so that the transmission belt contacts the side wall of the mold.

[0010] The function of any mold self-rotation driving mechanism is to drive the condom mold to rotate. The first mold self-rotation driving mechanism is correspondingly arranged with the first flanging roller. When the first mold self-rotation driving mechanism drives the condom mold to rotate, the first flanging roller flanging the condom prototype on the self-rotating mold. The second mold self-rotation driving mechanism is correspondingly arranged with the second flanging roller. When the second mold self-rotation driving mechanism drives the condom mold to rotate, the second flanging roller flanging the condom prototype on the self-rotating mold eliminates the distortion of the condom caused by the first flanging roller.

[0011] Any mold rotation driving mechanism acts on the upper part of the condom mold through the transmission belt to make the condom mold rotate.

[0012] The transmission structure includes a transmission chain and a mold base connected to the transmission chain. The mold base is connected to the transmission chain through a transmission connecting rod. The mold base includes a tail kit hinged to the transmission connecting rod and a mold base body pivotally connected to the tail kit. The mold base body is provided with a positioning groove, and the condom mold is inserted in the positioning groove. A mold base guide and limit structure is provided on the side of the transmission chain. The mold base guide and limit structure limits and guides the running trajectory of the mold base and the condom mold thereon.

[0013] The transmission chain drives the mold seat through the transmission connecting rod, and the mold seat drives the condom mold installed thereon. Since the mold seat is hinged to the transmission connecting rod, the mold seat and the condom mold thereon can swing up and down relative to the transmission connecting rod. Under the restriction and guidance of the mold seat guide limit structure, with the transmission of the transmission chain, the mold seat and the condom mold thereon can be in a lying state, an upright state, or an inclined state. When in the upright state, the condom mold can be immersed in the liquid rubber pool. When in the lying state, the flanging device located beside the transmission structure can flanging the condom prototype on the mold. When in the inclined state, the demoulding mechanism located beside the transmission structure can peel the condom formed on the condom mold from the mold.

[0014] The middle part of the transmission connecting rod is connected to the transmission chain, and the two ends of the transmission connecting rod are respectively connected to the mold base. The first flanging roller and the second flanging roller are provided on both sides of the transmission structure. In this way, the same transmission chain drives the two rows of condom molds on the left and right sides. Any flanging roller is equipped with a mold self-rotation drive mechanism, and the first flanging roller and the second flanging roller on both sides of the transmission structure simultaneously flanging the condom prototype on the corresponding mold to improve production efficiency.

[0015] Any flanging roller is installed on a support frame, and a flanging roller motor is provided on the support frame, and the flanging roller motor drives the flanging roller to rotate through a transmission mechanism. The support frame is installed on a bottom bracket, and the bottom bracket is fixed on the ground. Both ends of the flanging roller are pivotally connected to a bearing seat, and the bearing seat is installed on the support frame.

[0016] The transmission mechanism is a transmission chain. A driven sprocket is installed at one end of the flanging roller, a driving sprocket is installed on the flanging roller motor shaft, and the transmission chain is installed on the driven sprocket and the driving sprocket. Under the transmission of the transmission chain, the flanging roller motor drives the flanging roller to rotate.

The transmission wheel connected to the transmission wheel motor is the main transmission wheel, and the other transmission wheel is the slave transmission wheel. The pair of transmission wheels and the transmission wheel motor are installed on the top bracket, and the top bracket is fixed to the ceiling. The follower wheel is located on the inner ring of the transmission belt, and the transmission belt is stretched downward, so that the outer ring of the transmission belt acts on the side wall of the condom mold, so that each condom mold passing through the transmission belt rotates.

[0018] The follower wheel is mounted on a pair of columns. A spring is sleeved on the column. The top of the column is movably fitted in the guide cylinder. The guide cylinder is mounted on the fixed plate. The top of the spring is against the bottom of the guide cylinder. A limit plate is provided on the column that protrudes upward from the guide cylinder. A pair of columns are connected to both ends of the follower wheel shaft. The fixed plate is mounted on the top bracket, and the top bracket is mounted on the ceiling. Under the action of the spring, the column has a tendency to move downward, which causes the follower wheel to tighten the transmission belt so that the transmission belt is in close contact with the mold. The limit plate limits the maximum downward movement of the column and prevents the column from detaching from the guide cylinder.

[0019] The follower wheels of any mold rotation mechanism are in a row, and the length of a row of follower wheels is equivalent to the length of the corresponding flanging roller. In this way, the condom prototypes on several molds located between the row of follower wheels and the flanging roller can be flanging at the same time, thereby improving production efficiency.

[0020] A groove is provided on the outer circumference of the follower wheel, and the transmission belt is fitted in the groove and protrudes outward from the groove.

[0036] Combination Figure 1 , Figure 2 , Figure 5 The condom flanging combination structure includes a conveying structure 10 for conveying a condom mold 90, a first flanging roller 201 and a second flanging roller 202 arranged beside the conveying structure, and a mold rotation driving mechanism 30 capable of driving the condom mold to rotate. The first flanging roller 201 and the second flanging roller 202 are arranged front and back along the conveying direction of the conveying structure, and the first flanging roller and the second flanging roller are both inclined, with the rear end of the first flanging roller inclined outwardly and the front end of the second flanging roller inclined outwardly.

[0037] The flanging device of the present invention is arranged beside the conveying structure 10, the mold self-rotation driving mechanism 30 is installed on the top bracket, the top bracket is fixed on the ceiling, and the flanging roller 20 is finally supported by the bottom bracket 40. In this way, the condom mold 90 on the conveying structure 10 can pass between the mold self-rotation driving mechanism 30 and the flanging roller 20, so as to realize the production line of condoms.

[0038] Under the drive of the transmission structure 10, the condom mold 90 in a lying position passes between the mold self-rotation drive mechanism 30 and the flanging roller 20, and the drive belt 31 of the mold self-rotation drive mechanism acts on the upper part of the condom mold 90 to make the condom mold rotate; the flanging roller 20 acts on the lower part of the condom mold to flanging the condom prototype on the mold. In this way, the condom prototype on the mold 90 is flanging during the self-rotation process, and a better flanging effect can be obtained.

[0039] The first flanging roller 201 and the second flanging roller 202 are arranged at an angle. Specifically, the condom mold 90 conveyed by the conveying structure 10 is a row of molds, and a condom prototype is formed on each mold. The relationship between any flanging roller and the corresponding row of molds is inclined. A specific mold, under the conveyance of the conveying structure 10, first contacts with the front end of the flanging roller, and the front end of the flanging roller acts on the rear half of the mold. When the mold moves to the rear end of the flanging roller, the rear end of the flanging roller acts on the front half of the mold. In this way, the self-rotating flanging roller can effectively flanging the condom prototype on the mold.

[0040] Under the conveyance of the conveying structure 10, the mold 90 first passes through the first flanging roller 201 and then passes through the second flanging roller 202. Since the first flanging roller is inclined to the condom mold 90, the force of the first flanging roller 201 on the condom prototype is inclined to the condom mold, and the force is inclined forward. In this way, the flanging condom is twisted on the mold due to the inclined force. In order to eliminate this distortion, the present invention sets a second flanging roller 202 behind the first flanging roller 201. The force of the second flanging roller 202 on the condom on the mold is opposite to the force of the first flanging roller 201 on the condom, so that the twisted condom is reset to ensure the quality of the condom.

[0041] The first flanging roller 201 is equipped with a first mold self-rotation driving mechanism 301, and the second flanging roller 202 is equipped with a second mold self-rotation driving mechanism 302; the first mold self-rotation driving mechanism and the second mold self-rotation driving mechanism are located above the mold, and the first flanging roller and the second flanging roller are located below the mold, and the first mold self-rotation driving mechanism is located between the conveying structure 10 and the first flanging roller, and the second mold self-rotation driving mechanism is located between the conveying structure and the second flanging roller; any mold self-rotation driving mechanism includes a transmission belt 31 and a follower wheel 32, and the follower wheel presses the transmission belt toward the mold so that the transmission belt contacts the side wall of the mold.

[0042] The function of any mold self-rotation driving mechanism is to drive the condom mold to rotate. The first mold self-rotation driving mechanism 301 is arranged corresponding to the first flanging roller 201. When the first mold self-rotation driving mechanism drives the condom mold 90 to rotate, the first flanging roller 201 performs flanging on the condom prototype on the self-rotating mold. The second mold self-rotation driving mechanism 302 is arranged corresponding to the second flanging roller 201. When the second mold self-rotation driving mechanism 302 drives the condom mold 90 to rotate, the second flanging roller 202 performs flanging on the condom prototype on the self-rotating mold to eliminate the distortion of the condom caused by the first flanging roller.

[0043] Any mold rotation driving mechanism acts on the upper part of the condom mold 90 through the transmission belt 31 to make the condom mold rotate.

[0044] Combination Figure 1 , Figure 4The transmission structure 10 includes a transmission chain 11 and a mold base 12 connected to the transmission chain. The mold base is connected to the transmission chain through a transmission connecting rod 13. The mold base includes a tail kit 121 hinged to the transmission connecting rod and a mold base body 122 pivotally connected to the tail kit. The mold base body is provided with a positioning groove 123, and the condom mold 90 is inserted in the positioning groove; a mold base guide and limiting structure is provided on the side of the transmission chain 11, and the mold base guide and limiting structure limits and guides the running trajectory of the mold base and the condom mold thereon.

[0045] The transmission chain 11 drives the mold base 12 through the transmission connecting rod 13, and the mold base drives the condom mold 90 installed thereon. Since the mold base 12 is hinged with the transmission connecting rod 13, the mold base 12 and the condom mold 90 thereon can swing up and down relative to the transmission connecting rod 13. Under the restriction and guidance of the mold base guide and limit structure, with the transmission of the transmission chain 11, the mold base 12 and the condom mold 90 thereon can be in a lying state, an upright state, or an inclined state. When in an upright state, the condom mold 90 can be immersed in a liquid rubber pool. When in a lying state, the flanging device located beside the transmission structure 10 can flanging the condom prototype on the mold. When in an inclined state, the demoulding mechanism located beside the transmission structure can strip the condom formed on the condom mold from the mold. As an option, the mold base guide and limit structure is a guide bar 14, which includes an upright section, an inclined section, and a horizontal section connected end to end. When the mold base 12 is pressed against the horizontal section, the condom mold 90 is in a lying state. When the mold base 12 is pressed against the inclined section, the condom mold 90 is in an inclined state.

[0046] like Figure 3 , the flanging roller 20 is tilted. Specifically, the condom mold 90 conveyed by the conveying structure 10 is a row of molds, each mold is formed with a condom prototype, and the flanging roller 20 is tilted with respect to the row of molds. A specific mold moves forward under the conveyance of the conveying structure 10, and first contacts with the head end of the flanging roller 20. The head end of the flanging roller acts on the rear half of the mold. When the mold moves to the tail end of the flanging roller, the tail end of the flanging roller 20 acts on the front half of the mold. In this way, the self-rotating flanging roller 20 can effectively flanging the condom prototype on the mold 90.

[0047] like Figure 2 The flanging roller 20 is mounted on a support frame 21, and a flanging roller motor 22 is provided on the support frame. The flanging roller motor drives the flanging roller to rotate through a transmission mechanism 23. The support frame 21 is mounted on a bottom bracket 40, and the bottom bracket is fixed on the ground. Both ends of the flanging roller 20 are pivotally connected to a bearing seat 24, and the bearing seat is mounted on the support frame 21.

[0048] The transmission mechanism 23 is a transmission chain. A driven sprocket is installed at one end of the flanging roller 20, a driving sprocket is installed on the flanging roller motor shaft, and a transmission chain is installed on the driven sprocket and the driving sprocket. Under the transmission of the transmission chain, the flanging roller motor 22 drives the flanging roller 20 to rotate.

[0049] The transmission belt 31 is mounted on a pair of transmission wheels 33, and any one of the transmission wheels is driven by a transmission wheel motor. The transmission wheel connected to the transmission wheel motor is the main transmission wheel, and the other transmission wheel is the slave transmission wheel. The pair of transmission wheels and the transmission wheel motor are mounted on a top bracket, and the top bracket is fixed to the ceiling. The follower wheel 32 is located at the inner ring of the transmission belt 31, and the transmission belt 31 is stretched downward, so that the outer ring of the transmission belt acts on the side wall of the condom mold 90, so that each condom mold 90 passing through the transmission belt 31 rotates.

[0050] like Figure 5 The follower wheel 32 is mounted on a pair of columns 34. A spring 35 is sleeved on the column. The top of the column is movably fitted in the guide cylinder 36. The guide cylinder is mounted on a fixed plate 37. The top of the spring is against the bottom of the guide cylinder. A limit plate 38 is provided on the column protruding upward from the guide cylinder. A pair of columns 34 are connected to both ends of the follower wheel shaft. The fixed plate 37 is mounted on the top bracket, and the top bracket is mounted on the ceiling. Under the action of the spring 35, the column 34 has a tendency to move downward, which makes the follower wheel 32 hold the transmission belt 31 tightly, so that the transmission belt is in close contact with the mold. The limit plate 38 limits the maximum downward movement of the column 34 and prevents the column from detaching from the guide cylinder 36.

[0051] A groove is formed on the outer circumference of the follower wheel 32, and the transmission belt 31 fits in the groove and protrudes outward from the groove. The groove can effectively position the transmission belt 31. The portion of the transmission belt protruding outward from the groove abuts against the condom mold 90.
