DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present application will be described clearly and completely below. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0033] Referring to Figures 1-7 The utility model discloses a double position mould conveying device for lipstick machine, including the base plate 10, be provided with cooling section conveying channel 21 and take material section conveying channel 22 on the base plate 10, and the both ends of cooling section conveying channel 21 and the both ends of taking material section conveying channel 22 are vertically connected to form the mould conveying channel 20 of closed loop, be slidably connected with a plurality of paste forming mould 30 in the mould conveying channel 20, and the cooling window 11 that is communicated in cooling section conveying channel 21 is seted up on the base plate 10, and the cooling window 11 is used to provide cold air to cool the paste forming mould 30 that removes on cooling section conveying channel 21,

[0034] Cooling section conveying channel 21 is provided with a plurality of first linear channel 211, and the plurality of first linear channel 211 is sequentially vertically connected, and taking material section conveying channel 22 is provided with two second linear channel 221, and the two second linear channel 221 is parallel and vertically connected at the both ends of cooling section conveying channel 21, and the paste taking part 222 is provided on every second linear channel 221,

[0035] The double position mould conveying device further includes a plurality of pushing mechanisms 40 sequentially connected to each first linear channel 211 and second linear channel 221, and the pushing mechanisms 40 are used to push the paste forming mould 30 to move step by step along the mould conveying channel 20.

[0036] The double-station mold conveying device works, and a plurality of paste forming molds 30 are stepwisely slid in the closed-loop mold conveying channel 20 by the driving of the pushing mechanism 40. First, the liquid paste is injected into the paste forming mold 30 by the feeding mechanism, and then the paste forming mold 30 carrying the liquid paste is stepwisely moved into the cooling section conveying channel 21. Since the cooling section conveying channel 21 is composed of a plurality of first linear channels 211 which are vertically connected in sequence, and the substrate 10 is provided with cooling windows 11 which are connected to the cooling section conveying channel 21 and can provide cold air, the paste in the cooling section conveying channel 21 is cooled and solidified during the movement of the paste forming mold 30 along the first linear channels 211. Then, the cooled paste forming mold 30 is pushed by the pushing mechanism 40 into the taking section conveying channel 22. The two second linear channels 221 of the taking section conveying channel 22 are parallel to each other and vertically connected at both ends of the cooling section conveying channel 21, and each second linear channel 221 is provided with a paste taking part 222. Here, the molds on the two second linear channels 221 can be simultaneously operated to take the paste, realizing double-station operation. During the whole process, the pushing mechanism 40 is sequentially connected to each first linear channel 211 and second linear channel 221 to stepwisely move the paste forming mold 30 along the mold conveying channel 20, ensuring that the mold circulates according to the process.

[0037] Compared with the prior art, the double-station design of the device allows the paste on two molds to be taken at the same time on the taking section conveying channel 22, greatly improving the paste taking efficiency and overcoming the disadvantage that the existing package material clamp paste loading mechanism can only take the paste on one mold at a time. The cooling section conveying channel 21 is composed of a plurality of first linear channels 211 which are vertically connected in sequence, and the cold air supply of the cooling window 11 can fully and uniformly cool the mold during the movement, improving the paste cooling and molding quality. Moreover, the setting of a plurality of pushing mechanisms 40 ensures that the mold stepwisely moves stably and accurately in the complex closed-loop channel, ensuring the continuity and efficiency of the whole production process and providing strong support for the overall efficiency improvement of the lipstick production.

[0038] In addition, by adjusting the number of paste forming molds 30, the paste forming molds 30 can be distributed in a staggered manner, so that two types of paste forming molds 30 can be placed at the same time to achieve flexible selection of corresponding paste production according to the needs of two types of paste, that is, the equipment can only produce one type of paste structure, or according to the needs, the paste forming molds 30 for forming two types of paste are distributed in a staggered manner in the mold conveying groove 20, the number thereof is adjusted, so that one type of paste forming mold 30 is pushed into one section of the second straight groove 221, and the other type of paste forming mold 30 is pushed into the other section of the second straight groove 221. When one type of paste needs to be formed, only the paste liquid needs to be injected into one type of paste forming mold 30, and the other type of paste forming mold 30 is idle during the whole process. When the other type of paste needs to be formed, only the position of injecting the paste liquid and the amount of injecting the paste liquid need to be adjusted, and the paste taking mechanism such as the paste taking mechanism of the package material clamp described in the invention patent application publication No. CN114259120A can be used to take out the formed paste by setting two groups to respectively connect two paste taking parts 222, and the formed paste is taken out by the selection control mode. Of course, when the structures of the two types of paste only differ slightly, the two types of paste can also be formed at the same time, and only the types of the pastes need to be reasonably classified after the pastes are taken out. This greatly improves the flexibility and efficiency of the equipment in dealing with different sizes of paste production, and completely solves the problems of time waste and limited production flexibility caused by replacing a large number of molds to produce different sizes of paste in the past.

[0039] Please refer to Figure 2 , Figure 3 and Figure 7On the basis of the above technical scheme, further, the inner wall of the mold conveying channel 20 is provided with a sliding table part 23, a plurality of paste forming molds 30 are erected on the sliding table part 23, and can slide in the mold conveying channel 20 along the sliding table part 23, so that the paste forming mold 30 can move smoothly and stably; the paste forming mold 30 includes a mold main plate 31 slidably erected on the sliding table part 23 and at least one paste profiling silica gel piece 32 provided on the mold main plate 31 and extending into the inside of the mold conveying channel 20, and the paste profiling silica gel piece 32 is in abutment with the sliding table part 23; it can be convenient to profile the paste, and it can be flexible to adjust or replace the paste profiling silica gel piece 32 according to the shape and size requirements of different pastes, without the need to replace the whole mold, that is, the mold main plate 31 can be made into a structure suitable for the mold conveying channel, and different paste profiling silica gel pieces 32 are replaced to form different paste forming molds 30, and the silica gel material can be stretched, and after molding, the paste profiling silica gel piece 32 can be expanded by reverse vacuumizing, so as to facilitate taking out the paste molded in the paste profiling silica gel piece 32; compared with the traditional mold structure, the universality and production flexibility of the mold are greatly improved, the diversified lipstick production demand can be quickly responded, and the production efficiency and production convenience are further improved.

[0040] Please refer to Figures 1-3 On the basis of the above technical scheme, further, the plurality of paste forming molds 30 include a plurality of first paste forming molds 30 and a plurality of second paste forming molds 30, the plurality of first paste forming molds 30 and the plurality of second paste forming molds 30 are distributed in the cooling section conveying channel 21 in a staggered manner, and one of the second straight grooves 221 is arranged to receive the first paste forming mold 30, and the other of the second straight grooves 221 is arranged to receive the second paste forming mold 30. When the market has demand for pastes of different sizes or shapes, the device can process two different types of paste forming molds 30 at the same time in the same production process, without frequent replacement of the paste forming molds 30, effectively reducing the downtime caused by replacement of the molds, and greatly improving the production efficiency. For example, when the order demand of two types of pastes is not high each time, the two types of pastes can be generated by the device, that is, the first paste forming mold 30 corresponding paste is continuously output on one of the second straight grooves 221, and the second paste forming mold 30 corresponding paste is continuously output on the other of the second straight grooves 221. The whole process basically only changes the variety of paste, and basically only adjusts the parameters, without frequent replacement of the paste forming mold 30, thereby meeting the diversified market demand and enhancing the competitiveness of enterprises in the market, bringing higher economic benefits to lipstick production enterprises.

[0041] In order to realize flexible switching of the two types of paste production, further proposed is that one section of the second linear channel 221 is connected to the two ends of the cooling section conveying channel 21, and the other section of the second linear channel 221 is connected to the positions close to the two ends of the cooling section conveying channel 21, and the two sections of the second linear channel 221 are arranged with a paste forming mold 30 in between, so that the end of the cooling section conveying channel 21 connected to the taking section conveying channel 22 can accommodate exactly three paste forming molds 30; this layout greatly optimizes the connection and circulation efficiency of the molds during the conveying process. In the taking process, the two sections of the second linear channel 221 arranged in intervals, in combination with the end space that can accommodate three molds, can make different types of paste forming molds 30 more orderly enter the corresponding taking positions. Especially in the case of staggered distribution of two different types of paste forming molds 30, when the two different types of paste forming molds 30 flow from the second linear channel 221 to the first linear channel 211, it is only necessary to push them step by step by the pushing mechanism 40. When the two different types of paste forming molds 30 flow from the first linear channel 211 to the second linear channel 221, in terms of mold arrangement, one of the paste forming molds 30 flowing from the outermost side needs to be placed at the end of the cooling section conveying channel 21 in advance. By controlling the number of paste forming molds 30, so that every time two other paste forming molds 30 flow into the end of the cooling section conveying channel 21, the first flowing paste forming mold 30 and the pre-placed paste forming mold 30 are of the same type, thus, two types of paste forming molds 30 can be pushed into the two sections of the second linear channel 221 every time, and the paste forming mold 30 left at the end of the cooling section conveying channel will always be the pre-placed one. Of course, if the end of the cooling section conveying channel 21 connected to the taking section conveying channel 22 can accommodate more paste forming molds 30, for example, four, then two paste forming molds 30 need to be placed in advance.

[0042] Please refer to Figure 2 and Figure 5On the basis of the above technical solutions, further proposed to the two second straight slot 221 of the pusher mechanism 40 combined into one, including linear guide rail 41, belt transmission assembly 42, the first motor 43 and at least a group of lifting push assembly, linear guide rail 41, belt transmission assembly 42 and the first motor 43 are installed at the lower end of the base plate 10, the first motor 43 and belt transmission assembly 42 transmission connection, lifting push assembly slidingly connected on the linear guide rail 41 and with belt transmission assembly 42 transmission connection, lifting push assembly includes slidingly connected to the linear guide rail 41 and with belt transmission assembly 42 transmission connection of fixed seat 44, two lifting cylinders 45 installed on the fixed seat 44, installed on the piston end of lifting cylinder 45 lifting plate 46, and the positioning pin 47 installed on the lifting plate 46, the lower end of the paste forming die 30 is provided with a positioning hole 33 matched with the positioning pin 47, and the base plate 10 is provided with a let window 12 for the lifting plate 46 to extend into the mold conveying channel 20, two lifting cylinders 45 correspond to two second straight slot 221 respectively, after the positioning pin 47 is inserted into the positioning hole 33 driven by the lifting cylinder 45, the paste forming die 30 is moved along the material taking section conveying channel 22 by the first motor 43 driving the belt transmission assembly 42. Two lifting cylinders 45 correspond to two second straight slot 221 respectively, and the precise matching of the positioning pin 47 and the lower end positioning hole 33 of the paste forming die 30 can simultaneously or separately operate the paste forming die 30 on the two second straight slot 221 when needed; when moving the paste forming die 30, the positioning pin 47 is inserted into the positioning hole 33 driven by the lifting cylinder 45, and then the mold is moved along the material taking section conveying channel 22 by the first motor 43 driving the belt transmission assembly 42, which ensures the accuracy and stability of the mold moving. Moreover, the let window 12 provided on the base plate 10 enables the lifting plate 46 to smoothly extend into the mold conveying channel 20, ensuring the effective action of the lifting push assembly on the mold, realizing the efficient, synchronous or asynchronous moving of different types of paste forming die 30 on the two second straight slot 221, further improving the operation efficiency and production flexibility of the double station mold conveying device, and providing strong support for the automation and high efficiency of lipstick production.

[0043] Please refer to Figure 1 and Figure 3On the basis of the above technical scheme, the first and second paste forming molds 30 are pushed from the two second linear grooves 221 to the first linear groove 211, and the pushing mechanism 40 connected to the first linear groove 211 is provided with two displacements to push the first and second paste forming molds 30 entering the first linear groove 211 at the same time twice in a step-by-step manner. After the first and second paste forming molds 30 are pushed from the two second linear grooves 221 to the first linear groove 211, the pushing mechanism 40 connected to the first linear groove 211 is provided with two displacements, which can effectively realize the separate and orderly pushing of different types of molds. On the one hand, for the two paste forming molds 30, through twice step-by-step pushing, it can ensure that they move in the first linear groove 211 according to the predetermined production rhythm and process requirements, avoid the pushing conflict caused by the simultaneous entry of the two paste forming molds 30, and ensure the smooth progress of the cooling process. The traditional pushing method is realized by a pneumatic cylinder. In order to achieve precise two displacements, the pneumatic cylinder pushing can be replaced by a lead screw pushing or other power mechanisms, which is a simple replacement of a conventional means, so the technical scheme will not be described in detail.

[0044] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7On the basis of the above technical solutions, the mold main plate 31 is further provided in a long strip structure, the paste profiled silica gel part 32 is provided in a plurality of uniform arrangement along the lateral direction of the mold main plate 31, the mold main plate 31 is formed with a long side portion and a short side portion through the long strip structure, the first auxiliary leveling mechanism is arranged on the wall surface of the first linear channel 211 or the second linear channel 221 and abuts against the long side portion of the paste forming mold 30, the first auxiliary leveling mechanism comprises a leveling cylinder 24 fixed outside the mold conveying channel 20 and a leveling frame 25 connected to the piston end of the leveling cylinder 24, and the leveling frame 25 is driven by the leveling cylinder 24 to extend into the mold conveying channel 20 to support the lower end of the mold main plate 31 of the paste forming mold 30 conveyed. The beneficial effects of the structure design are remarkable. The mold main plate 31 is provided in a long strip structure, and the plurality of paste profiled silica gel parts 32 are uniformly arranged along the lateral direction of the mold main plate 31. This design makes the paste forming mold 30 have good layout rationality and stability when bearing and forming paste. The first auxiliary leveling mechanism arranged on the wall surface of the first linear channel 211 or the second linear channel 221 and abutting against the long side portion of the paste forming mold 30 plays a key role. When the paste forming mold 30 is conveyed in the channel, the leveling cylinder 24 drives the leveling frame 25 to extend out, which can timely and effectively support the lower end of the mold main plate 31 conveyed. This not only prevents the long strip structure of the mold main plate 31 from shaking or tilting during the conveying to the end portion, but also ensures the stability of the mold during the conveying.

[0045] In addition, during the conveying of the long strip paste forming mold 30, considering the arrangement of the double stations, the paste forming mold 30 may be tilted and dumped when flowing into or out of the taking section conveying channel 22 without the sliding table portion 23. To this end, the first leveling plate 26 is arranged at the positions of the two ends of the cooling section conveying channel 21 and is matched with the paste profiled silica gel part 32, and the first leveling plate 26 is further matched with the two ends of the second linear channel 221. The first leveling plate 26 can form a structure simulating the sliding table portion 23, so that the paste forming mold 30 can smoothly complete the turning movement between the first linear channel 211 and the second linear channel 221. The first leveling plate 26 can be matched with the paste profiled silica gel part 32 and the two ends of the second linear channel 221, and form a structure simulating the sliding table portion 23. This makes the paste forming mold 30 have reliable support when turning between the first linear channel 211 and the second linear channel 221, avoids the dumping phenomenon caused by the lack of the sliding table portion 23, and ensures the stability and safety of the mold conveying.

[0046] The second flat plate 27 corresponding to the second straight line groove 221 is arranged at the position close to the end of the cooling section conveying groove 21, and the inclined push cylinder 28 for driving the second flat plate 27 to extend and retract in the cooling section conveying groove 21 is arranged at the lower end of the base plate 10; when the second flat plate 27 extends into the cooling section conveying groove 21, the second flat plate 27 is used for supporting the paste forming mold 30 to slide along the direction of the cooling section conveying groove 21 at the position, which can strongly support the paste forming mold 30 to slide along the direction of the cooling section conveying groove 21, and ensures the stability of the mold during the cooling process; when the second flat plate 27 is retracted, the paste forming mold 30 is slid along the direction of the material taking section conveying groove 22 at the position, which avoids the paste profiled silica gel part 32, realizes the effective switching of the mold conveying path in different production stages, greatly improves the reliability and operation efficiency of the double-station mold conveying device, and guarantees the continuity and high efficiency of the lipstick production process.

[0047] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
