Description

Technical Field

[0001] The present application relates to the technical field of candle packaging, and in particular to a candle packaging process. Background Art

[0002] Aromatherapy candles are a type of craft candles. They have a fresh and pleasant scent. In addition, they are beautiful in color and emit a pleasant fragrance during the burning process. Therefore, they are usually installed in a cup to be used as an embellishment to create a romantic atmosphere. Aromatherapy candles installed in a cup are called cup candles. To make a cup candle, it is usually necessary to process the cup first, then set the candle wick in the cup, and then inject candle slurry into the cup to finally complete the finished product.

[0003] Some prior arts use a method of multiple multi-head operation when injecting candle slurry. This process method not only has low wax injection accuracy and a long production line, but also makes it difficult to ensure consistent filling quality. Summary of the invention

[0004] The present application aims to solve at least one of the technical problems existing in the prior art. To this end, the present application proposes a candle packaging process to improve the accuracy and quality of candle packaging.

[0005] The present application provides a candle packaging process, comprising the following steps: S1. The material is moved to the loading station through the feeding line; S2, the pushing mechanism pushes the material at the loading station to the filling line; S3, the heating mechanism heats the material; S4, the clamping mechanism organizes the material and lifts the material to a position close to the filling port of the filling tank; S5, open the filling port and start filling; S6. After filling is completed, the air extraction mechanism performs air extraction; S7, the cooling mechanism cools the material and the filling inside the material; S8, the feeding mechanism feeds and fills the material; S9. The heating mechanism is used to heat the material again so that the filling materials of the two fillings in the material are integrated.

[0006] Based on the candle packaging process, the feeding and filling are respectively arranged on two separate production lines to avoid mutual interference. The material on the feeding production line can be transferred to the filling production line by using the pushing mechanism, and a regular action is realized. At the same time, before the material is filled, the material will be preliminarily heated to make it have a certain temperature to avoid the liquid filling material flowing out of the filling port from solidifying instantly when it contacts the inner wall of the material, which affects the subsequent filling effect. Through the setting of the clamping mechanism, the material can be secondary regularized before filling, and the material can be lifted to a certain height at the same time, so that the filling can be completed at a position close to the filling port, which can not only improve the filling effect, reduce the influence of the filling material being cooled by air after flowing out of the filling port, but also reduce splashing and improve the utilization rate of the filling material; and through the setting of the exhaust mechanism, the cooling mechanism, the feeding mechanism and the secondary heating mechanism, the filling material in the material can be repeatedly exhausted, cooled, fed and heated, and the top surface of the final solid filling material approaches the horizontal plane, and the filling amount in all materials tends to be consistent, which improves the filling effect.

[0007] Optionally, step S1 also includes: placing the material into the feeding mechanism, the feeding mechanism transports the material to the position of the wick installation mechanism through the first feeding conveyor belt, and installing the wick tooling, the first feeding conveyor belt transports the material in the wick installation mechanism to the transfer mechanism, and the material is then transported to the loading station opposite to the pushing mechanism through the second feeding conveyor belt.

[0008] Furthermore, based on the setting of the above-mentioned loading line, the transfer mechanism is used as a turning point, and the overall arrangement is L-shaped, so as to form a C-shaped structure in combination with the filling line as a whole, effectively reducing the occupied area of ​​the packaging line used in the candle packaging process.

[0009] Optionally, the feeding mechanism includes a feeding tray with a disc structure and a feeding pushing assembly, the feeding tray includes a feeding bottom plate and a feeding ring wall surrounding the circumference of the feeding bottom plate, a first discharge port is provided on the side wall of the feeding ring wall, and an avoidance groove for accommodating at least part of the first loading conveyor belt is provided on the feeding bottom plate, so that at least part of the first loading conveyor belt is flush with the top of the feeding bottom plate, the part of the first loading conveyor belt located in the feeding tray is used to transport the material to the first discharge port, and the feeding pushing assembly is used to push the material on the feeding bottom plate to the first loading conveyor belt or the position of the first discharge port.

[0010] Furthermore, based on the above-mentioned feeding mechanism, the feeding and pushing assembly and part of the first loading conveyor belt can be used to quickly feed the material in the feeding tray, thereby improving the output efficiency and reducing the probability of the material staying in the feeding tray.

[0011] Optionally, the step S1 also includes: the second feeding conveyor belt first conveys the material to the partition component, the partition component conveys all the materials to the feeding space in sequence, and the materials in the feeding space are then driven by the second feeding conveyor belt to move to the corresponding feeding station.

[0012] Furthermore, based on the above-mentioned separation component, continuous materials can be adjusted to have a set interval and maintain a set gap to avoid the distance between two materials being too small, which affects the regular movement before pushing the materials.

[0013] Optionally, the partition assembly includes a partition shaft and a partition plate, a plurality of the partition plates are evenly arranged in the circumferential direction on the circumferential side of the partition shaft, a partition space for accommodating a material is formed between every two of the partition plates, the partition shaft is rotatably set in the position where the pushing mechanism receives the material, and the partition shaft extends in the vertical direction; the pushing mechanism includes a pushing block, the pushing guide surface is formed at the end of the pushing block facing the partition assembly, and the pushing guide surface and the partition space together surround the loading space.

[0014] Furthermore, based on the above-mentioned partitioning assembly, it is possible to achieve the displacement of materials to the loading station one by one, thereby avoiding the accumulation of materials at the position of the pushing mechanism.

[0015] Optionally, step S4 also includes: the clamping mechanism rises to a set height before the material reaches directly below the filling port, and when the material reaches directly below the filling port, the in-place sensor detects that the material moves to the filling station. At this time, the two clamping arms in the clamping mechanism begin to descend and are respectively located on both sides of the material. The two clamping arms then begin to approach each other to clamp and fix the material, and then lift the material to a position close to the filling port.

[0016] Furthermore, based on the above-mentioned clamping mechanism, the material can be regulated and fixed before filling, and the material can be separated from the filling conveyor belt to avoid the filling conveyor belt affecting the filling of the material. The clamping mechanism can also drive the material close to the filling port to achieve a better filling effect and reduce splashing of the filling material.

[0017] Optionally, step S4 also includes: before the two clamping arms approach each other to clamp the material, the two clamping arms are first rotated by a certain angle so that the tops of the clamping grooves on the two clamping arms first contact the outer wall of the material; when the clamping grooves on both sides are in contact with the outer wall of the material, the two clamping arms continue to apply a clamping force to the material, and the two clamping arms rotate themselves and utilize the friction with the outer wall of the material to lift the material to the filling conveyor belt that leaves the filling line.

[0018] Furthermore, based on the above-mentioned clamping mechanism, the two clamping arms will align the material with the filling port while approaching each other. After the two clamping arms clamp the material, the contact area between the two and the outer wall of the material is very small (only the top part of the clamping groove is in contact with the material), thereby reducing the friction of the two clamping arms on the outer wall of the material. After clamping the material, the contact area between the clamping arms and the material is gradually increased by rotating the clamping arms, thereby reducing the friction with the material caused by the uneven heights of the clamping arms on both sides. When the two clamping arms rotate, the position of contact with the material is constantly rising, thereby driving the material to gradually rise and make the material separate from the filling conveyor belt, thereby avoiding the shaking and vibration of the filling conveyor belt itself from affecting the filling work.

[0019] Optionally, the filling line also includes a cleaning mechanism, which is arranged within the coverage range of at least one of the heating mechanisms. The cleaning mechanism includes a cleaning piece, a cleaning seat, a first elastic piece and a cleaning track. The cleaning piece is arranged on the cleaning seat and contacts the bottom surface of the filling conveyor belt in the filling line. The cleaning seat is slidably arranged on the cleaning track along the movement direction of the filling conveyor belt. The two ends of the first elastic piece are respectively connected to the cleaning seat and the cleaning track, and are used to provide the cleaning seat with an elastic force that is the same as or opposite to the movement direction of the filling conveyor belt.

[0020] Furthermore, based on the above-mentioned cleaning mechanism, not only can the outer surface of the filling conveyor belt be cleaned, but also the temperature of the heating mechanism can be used to heat and soften the fillings on the filling conveyor belt, so that the cleaning mechanism can more conveniently scrape the fillings and make it easier for the fillings to separate from the filling conveyor belt, thereby improving the cleaning efficiency of the cleaning mechanism; through the setting of the first elastic member, the thrust of the cleaning member pushed by the filling conveyor belt can be coordinated with the thrust of the cleaning member, so that the cleaning member can continuously reciprocate in the first direction or the opposite direction, thereby improving the cleaning effect, and the cleaning mechanism not only does not require a power source, but also can use the heating effect of the heating mechanism on the filling conveyor belt to improve the cleaning effect of the cleaning mechanism, and does not occupy additional space.

[0021] Optionally, the cleaning mechanism also includes a second elastic member and a cleaning slider, the cleaning slider is slidably set on the cleaning seat along the movement direction of the filling conveyor belt, a plurality of cleaning sliders are evenly arranged on the cleaning seat, the second elastic member is set between every two adjacent cleaning sliders, and is used to provide the cleaning slider with an elastic force that is the same or opposite to the movement direction of the filling conveyor belt.

[0022] Furthermore, based on the above-mentioned cleaning mechanism, through the cooperation of the first elastic member, the second elastic member, the cleaning slider, the cleaning seat and the cleaning track, after the cleaning member is subjected to the thrust of the filling conveyor belt, the cleaning member located at the end along the movement direction moves to the extreme position in the first direction. At this time, all the cleaning members at the rear drive the cleaning slider below to start squeezing or stretching the second elastic member on its front side, and the cleaning seat also starts to squeeze or stretch the first elastic member. Through the joint action of multiple first elastic members and multiple second elastic members, combined with the unstable thrust of the filling conveyor belt on the cleaning member, a double shaking effect can be created. By utilizing the frequent shaking of multiple cleaning members, the cleaning effect of the cleaning mechanism on the filling conveyor belt can be significantly improved.

[0023] Optionally, the cleaning mechanism also includes a tensioning assembly, which includes a plurality of tensioning rollers supported on the inner surface and / or outer surface of the filling conveyor belt, wherein two adjacent tensioning rollers are supported on the inner surface of the filling conveyor belt to form a cleaning area, and the cleaning member contacts the outer surface of the filling conveyor belt located in the cleaning area.

[0024] Furthermore, based on the above-mentioned tensioning assembly, at least two tensioning rollers extending along the second direction can be used to tension the filling conveyor belt, so that the filling conveyor belt corresponding to the cleaning mechanism is in a tensioned state, thereby further ensuring that all cleaning parts can be cleaned reliably and evenly, thereby improving the cleaning effect of the filling conveyor belt.

[0025] One or more of the above embodiments of the present application have at least one or more of the following beneficial effects: The feeding and filling are arranged on two separate production lines to avoid mutual interference. The material on the feeding production line can be transferred to the filling production line by using the pushing mechanism, and a regular action is realized. At the same time, before the material is filled, the material will be preliminarily heated to make it have a certain temperature to avoid the liquid filling material flowing out of the filling port from solidifying instantly when it contacts the inner wall of the material, which affects the subsequent filling effect. Through the setting of the clamping mechanism, the material can be secondary regularized before filling, and the material can be lifted to a certain height at the same time, so that the filling can be completed at a position close to the filling port, which can not only improve the filling effect, reduce the influence of the filling material being cooled by air after flowing out of the filling port, but also reduce splashing and improve the utilization rate of the filling material; and through the setting of the exhaust mechanism, the cooling mechanism, the feeding mechanism and the secondary heating mechanism, the filling material in the material can be repeatedly exhausted, cooled, fed and heated, and the top surface of the final solid filling material approaches the horizontal plane, and the filling amount in all materials tends to be consistent, which improves the filling effect.

DETAILED DESCRIPTION

[0029] Some embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present application and are not intended to limit the protection scope of the present application.

[0030] Since wax is solid at room temperature, it needs to be turned into liquid state by high temperature before filling. However, the temperature should not be too high to prevent the wax from shrinking too much during solidification and affecting the appearance of the product. It is usually about 5°C above the melting point of the wax.

[0031] Some filling methods in the prior art use a method of multiple multi-head operations. This process method not only has low wax filling accuracy and a long production line, but also makes it difficult to ensure consistent filling quality.

[0032] Based on this, the present application provides a candle packaging process, in which the loading and filling are respectively arranged on two separate assembly lines to avoid mutual interference. The material on the loading assembly line can be transferred to the filling assembly line by means of a pushing mechanism, and a regular action can be achieved. At the same time, before the material is filled, the material will be preliminarily heated to make it have a certain temperature to avoid the liquid filling material flowing out of the filling port from solidifying instantly when it contacts the inner wall of the material, thereby affecting the subsequent filling effect. By setting the clamping mechanism, the material can be heated twice before filling. The material can be raised to a certain height to complete the filling near the filling port, which can not only improve the filling effect and reduce the influence of the filling being cooled by air after flowing out of the filling port, but also reduce splashing and improve the utilization rate of the filling material; and, through the arrangement of the air extraction mechanism, the cooling mechanism, the feeding mechanism and the secondary heating mechanism, the filling material in the material can be repeatedly exhausted, cooled, fed and heated, and the top surface of the final solid filling material approaches the horizontal plane, and the filling amount in all materials tends to be consistent, thereby improving the filling effect.

[0033] The present application will be described in detail below through specific embodiments.

[0034] Reference Figures 1 to 8 As shown, this embodiment provides a candle packaging process, comprising the following steps: S1. Material 1 is moved to the loading station through the conveyor of the loading line, wherein material 1 can be a container such as a cup or a box that can hold fillings; S2, the pushing mechanism pushes the material 1 at the loading station onto the filling line; S3, the heating mechanism 2 heats the material 1; S4, the clamping mechanism 3 arranges the material 1 and lifts the material 1 to a position close to the filling port 41 of the filling tank 4, wherein the filling tank 4 has a heating structure to ensure that the filling material in the filling tank 4 always remains in a flowable state and ensures smooth filling. The filling tank 4 can extract the filling material from the storage structure through structures such as pipelines and pumps. The filling tank 4 can also be directly used as a storage structure to store a large amount of filling material; S5, opening the filling port 41 to perform filling. Furthermore, the filling port 41 can be opened and closed by a valve or other structure; S6. After filling, the exhaust mechanism 5 performs exhaust treatment to extract some harmful gases in the filled material 1 to ensure environmental protection and health; S7, the cooling mechanism 6 cools the material 1 and the filling inside the material 1 to solidify the filling; S8, the feeding mechanism 7 feeds and fills the material 1, wherein the feeding mechanism 7 can be composed of a filling tank 4, a filling port 41 and a clamping mechanism 3. Since a pit is likely to appear at the top center after the filling solidifies, it is necessary to feed the material to ensure the filling effect; S9. Use the heating mechanism 2 to heat the material 1 again to integrate the two fillings in the material 1. It should be understood that the four mechanisms of the exhaust mechanism 5, the cooling mechanism 6, the feeding mechanism 7 and the heating mechanism 2 for heating the material 1 again can be a set of assemblies, and the number of the assemblies is not less than one set, that is, the filling work can be completed after two, three, four or even more times of filling and feeding, thereby ensuring that the filling amount in all materials 1 tends to be consistent and the top surface is close to horizontal.

[0035] The candle packaging process provided in this embodiment sets the feeding and filling on two separate production lines respectively to avoid mutual interference. The material 1 on the feeding production line can be transferred to the filling production line by using the pushing mechanism, and a regular action is achieved. At the same time, before the material 1 is filled, the material 1 will be preliminarily heated to make it have a certain temperature to avoid the liquid filling material flowing out of the filling port 41 from solidifying instantly when it contacts the inner wall of the material 1, affecting the subsequent filling effect. By setting the clamping mechanism 3, the material 1 can be secondarily regularized before filling. At the same time, the material 1 can be lifted to a certain height so that the filling can be completed at a position close to the filling port 41, which can not only improve the filling effect and reduce the influence of the filling material being cooled by air after flowing out of the filling port 41, but also reduce splashing and improve the utilization rate of the filling material; and, through the arrangement of the exhaust mechanism 5, the cooling mechanism 6, the feeding mechanism 7 and the secondary heating, the filling material in the material 1 can be repeatedly exhausted, cooled, fed and heated, and the top surface of the final solid filling material approaches the horizontal plane, and the filling amount in all the materials 1 tends to be consistent, thereby improving the filling effect.

[0036] Optionally, step S1 also includes: placing material 1 into the feeding mechanism 81, the feeding mechanism 81 conveys the material 1 to the position of the wick installation mechanism 83 through the first loading conveyor belt 821, and installing the wick tooling 834, the first loading conveyor belt 821 conveys the material 1 in the wick installation mechanism 83 to the transfer mechanism, and the material 1 is then conveyed to the loading station opposite to the pushing mechanism through the second loading conveyor belt 822; wherein, the conveying directions of the first loading conveyor belt 821 and the second loading conveyor belt 822 can be perpendicular to each other, the extension directions of the second loading conveyor belt 822 and the filling assembly line can be perpendicular to each other, the first loading conveyor belt 821 and the filling assembly line can be located on the same side of the second loading conveyor belt 822, forming a C-type arrangement; further, the conveying direction of the first loading conveyor belt 821 is a first direction, the conveying direction of the filling assembly line is the opposite direction of the first direction, and the conveying direction of the second loading conveyor belt 822 is a second direction.

[0037] Furthermore, based on the setting of the above-mentioned loading line, the transfer mechanism is used as a turning point, and the overall arrangement is L-shaped, so as to form a C-shaped structure in combination with the filling line as a whole, effectively reducing the occupied area of ​​the packaging line used in the candle packaging process.

[0038] Continue to refer to Figure 1 and Figure 2 As shown, the wick installation mechanism 83 includes a material positioning component and a wick installation component. The material positioning component includes a rotatable material positioning disk 831 and material positioning grooves 8311 evenly arranged along the circumference of the material positioning disk 831. The material positioning grooves 8311 are used to receive or send out the material 1; the wick installation component includes a rotatable wick turntable 832 and wick conveying rods 833 evenly arranged on the wick turntable 832 along the circumference. The rotating shafts of the material positioning disk 831 and the wick turntable 832 and the wick conveying rods 833 are The axial direction of the rod 833 extends in the vertical direction (the third direction). When the wick turntable 832 and the material positioning disk 831 are rotated to the set angle, one of the wick conveying rods 833 and one of the material positioning grooves 8311 move to a coaxial position, and the material 1 located in the material positioning groove 8311 is configured to receive the wick tooling 834 on the wick conveying rod 833 above it; the bottom end of the wick conveying rod 833 can be extended and retracted in the vertical direction, and the bottom end of the wick conveying rod 833 is used to clamp or release the wick tooling 834.

[0039] Optionally, the wick installation mechanism 83 also includes a tooling positioning disk 835 coaxially arranged with the wick turntable 832, and the two rotate synchronously. The tooling positioning disk 835 is provided with wick passing holes 8351 corresponding to the multiple wick conveying rods 833. When the wick conveying rod 833 installs the wick tooling 834 on the material 1, it is necessary to first pass through the corresponding wick passing hole 8351. When the wick tooling 834 interferes with the tooling positioning disk 835, the installation of the wick tooling 834 is canceled, and the next wick tooling 834 is adjusted for installation.

[0040] Continue to refer to Figure 1 and Figure 2 As shown, the feeding mechanism 81 includes a feeding tray 811 of a disc structure and a feeding pushing assembly. The feeding tray 811 includes a feeding bottom plate 8111 and a feeding ring wall 8112 surrounding the circumference of the feeding bottom plate 8111. A first discharge port is provided on the side wall of the feeding ring wall 8112. An avoidance groove for accommodating at least part of the first loading conveyor belt 821 is provided on the feeding bottom plate 8111, so that at least part of the first loading conveyor belt 821 is flush with the top of the feeding bottom plate 8111. The part of the first loading conveyor belt 821 located in the feeding tray 811 is used to transport the material 1 to the first discharge port. The feeding and pushing assembly is used to push the material 1 on the feeding bottom plate 8111 to the first loading conveyor belt 821 or the first discharge port; it should be understood that the feeding ring wall 8112 is provided with a discharge port at a position located on the first loading conveyor belt 821, and the first loading conveyor belt 821 can directly drive the material 1 in the feeding ring wall 8112 to move from the discharge port to the position of the wick mounting mechanism 83. The feeding ring wall 8112 can be provided with an opening above or a first feed port on the peripheral side, and the material 1 can be placed into the feeding tray 811 through the opening or the first feed port.

[0041] Furthermore, based on the above-mentioned feeding mechanism 81, the feeding and pushing assembly and part of the first loading conveyor belt 821 can be used to quickly feed out the material 1 in the feeding tray 811, thereby improving the output efficiency and reducing the probability of the material 1 staying in the feeding tray 811.

[0042] In some embodiments, the feeding and pushing assembly includes a feeding paddle 8121 and a feeding and pushing motor 8122. The feeding and pushing motor 8122 is coaxially arranged with the feeding disk 811. The output shaft of the feeding and pushing motor 8122 is connected to the feeding paddle 8121 and is used to drive the feeding paddle 8121 to rotate around the output shaft of the feeding and pushing motor 8122. At least part of the feeding paddle 8121 extends radially along the feeding disk 811 and is used to push the material 1 toward the first discharge port; wherein, the pushing surface of the feeding paddle 8121 is an arc-shaped surface, and the concave side faces the movement direction of the feeding paddle 8121, that is, the concave side of the feeding paddle 8121 is the front side, and when the feeding paddle 8121 rotates, the concave side pushes the material 1 toward the first discharge port, and by setting the pushing surface of the feeding paddle 8121 to an arc-shaped surface, the material 1 can be gathered while pushing the material, thereby further improving the efficiency of conveying the material 1 outward.

[0043] In some further embodiments, the feed paddle 8121 can be an elastic structure, that is, when the material 1 or other structures in the feed tray 811 form a sufficiently large resistance to the feed paddle 8121, the feed paddle 8121 can use its own elastic deformation to avoid the feed paddle 8121 from getting stuck and causing damage to the material 1.

[0044] Furthermore, the conveying direction of the first loading conveyor belt 821 is perpendicular to a diameter in the feed tray 811. Specifically, the intersection of the first loading conveyor belt 821 and the diameter is located at a position on the diameter away from the center of the feed tray 811, thereby enabling the material 1 moving onto the first loading conveyor belt 821 to have a sufficient initial velocity, thereby improving the matching degree of the material 1 at the moment of displacement onto the first loading conveyor belt 821, and thereby improving the stability of the material 1 after it is displaced onto the first loading conveyor belt 821.

[0045] Continue to refer to Figure 1 and Figure 2 As shown, along the rotation direction of the feeding paddle 8121, the end of the feeding paddle 8121 close to the feeding ring wall 8112 is located on the rear side of the end of the output shaft of the feeding pushing motor 8122. Combined with the arc surface structure, the material 1 can be gradually guided to the outside of the feeding ring wall 8112 during the process of pushing the material 1, so that its linear speed is faster, and it can also be closer to the first discharge port, further improving the discharge efficiency.

[0046] Optionally, the end of the feed paddle 8121 close to the feed ring wall 8112 is at a set angle to its movement direction, and the set angle is close to 90 degrees, so that when the outer end of the feed paddle 8121 pushes the material 1, the speed of the material 1 is made consistent with the linear speed direction of the rotation of the feed paddle 8121, thereby improving the smoothness of the material 1 entering the first discharge port and effectively increasing the initial velocity of the material 1 when it moves to the first loading conveyor belt 821.

[0047] In some embodiments, the first loading conveyor belt 821 has a first track plate 8211 and a second track plate 8212 arranged in parallel, and there is a gap between the first track plate 8211 and the second track plate 8212 that is slightly larger than the outer diameter of the material 1 to form a channel for transporting the material 1. The first track plate 8211 and the second track plate 8212 can reduce the risk of the material 1 falling to the outside of the first loading conveyor belt 821 during transportation.

[0048] Furthermore, the feeding ends of the first track plate 8211 and the second track plate 8212 pass through the first discharge port and extend to the diameter position on the feeding bottom plate 8111 that is perpendicular to the first loading conveyor belt 821, wherein the first track plate 8211 is farther from the axis of the feeding tray 811 than the second track plate 8212, and the end of the first track plate 8211 extending into the feeding tray 811 is provided with a first guide plate 8213, and / or the end of the second track plate 8212 extending into the feeding tray 811 is provided with a second guide plate 8214; the first guide plate 8213 and / or the second guide plate 8214 form an open structure at the passage opening where the material 1 enters the first track plate 8211 and the second track plate 8212, thereby achieving a guiding effect on the material 1.

[0049] In a further embodiment, the first guide plate 8213 is rotatably connected to the first track plate 8211, and the first guide plate 8213 has an opening position and a closing position. When the first guide plate 8213 is located at the opening position, the first guide plate 8213 has an open structure at the channel opening, and when the first guide plate 8213 is located at the closing position, the first guide plate 8213 blocks the channel opening and is used to prevent material 1 from entering the channel; and / or, the second guide plate 8214 is rotatably connected to the second track plate 8212, and the second guide plate 8214 has an opening position and a closing position. When the second guide plate 8214 is located at the opening position, the second guide plate 8214 has an open structure at the channel opening, and when the second guide plate 8214 is located at the closing position, the second guide plate 8214 blocks the channel opening and is used to prevent material 1 from entering the channel.

[0050] In some embodiments, the transfer mechanism can be similar in structure to the feeding mechanism 81, wherein the transfer mechanism can include a transfer tray 851 and a transfer pushing assembly, the transfer tray 851 includes a transfer bottom plate 8511 and a transfer ring wall 8512, and the transfer ring wall 8512 is staggered with a second inlet and a second outlet, wherein the second inlet is connected to the first loading conveyor belt 821, and the second outlet is connected to the second loading conveyor belt 822, and the transfer pushing assembly is used to push the material 1 on the transfer bottom plate 8511 to the second loading conveyor belt 822 or the position of the second outlet.

[0051] In some embodiments, the transfer pushing assembly includes a transfer paddle 8521 and a transfer pushing motor 8522. The transfer pushing motor 8522 is coaxially arranged with the transfer disc 851. The output shaft of the transfer pushing motor 8522 is connected to the transfer paddle 8521 and is used to drive the transfer paddle 8521 to rotate around the output shaft of the transfer pushing motor 8522. At least part of the transfer paddle 8521 extends radially along the transfer disc 851 and is used to push the material 1 toward the second discharge port; wherein, the pushing surface of the transfer paddle 8521 is an arcuate surface, and the concave side faces the movement direction of the transfer paddle 8521, that is, the concave side of the transfer paddle 8521 is the front side, and when the transfer paddle 8521 rotates, the concave side pushes the material 1 toward the second discharge port. By setting the pushing surface of the transfer paddle 8521 to an arcuate surface, the material 1 can be gathered while pushing the material, thereby further improving the efficiency of conveying the material 1 outward.

[0052] In some further embodiments, the transfer paddle 8521 can be an elastic structure, that is, when the material 1 or other structures in the transfer plate 851 form a sufficiently large resistance to the transfer paddle 8521, the transfer paddle 8521 can use its own elastic deformation to avoid the transfer paddle 8521 from getting stuck and causing damage to the material 1.

[0053] Furthermore, the conveying direction of the second loading conveyor belt 822 is perpendicular to a diameter in the transfer disc 851. Specifically, the intersection of the second loading conveyor belt 822 and the diameter is located at a position on the diameter away from the center of the transfer disc 851, thereby enabling the material 1 moving onto the second loading conveyor belt 822 to have a sufficient initial velocity, thereby improving the matching degree of the material 1 at the moment of displacement onto the second loading conveyor belt 822, and thereby improving the stability of the material 1 after it is displaced onto the second loading conveyor belt 822.

[0054] Optionally, along the rotation direction of the transfer paddle 8521, the end of the transfer paddle 8521 close to the transfer ring wall 8512 is located on the rear side of the end of the output shaft close to the transfer pushing motor 8522. Combined with the arc surface structure, the material 1 can be gradually guided to the outside of the transfer ring wall 8512 during the process of pushing the material 1, so that its linear speed is faster, and it can also be closer to the second discharge port, further improving the discharge efficiency.

[0055] Optionally, the end of the transfer paddle 8521 close to the transfer ring wall 8512 is at a set angle with its movement direction, and the set angle is close to 90 degrees, so that when the outer end of the transfer paddle 8521 pushes the material 1, the speed of the material 1 is made consistent with the linear speed direction of the rotation of the transfer paddle 8521, thereby improving the smoothness of the material 1 entering the second discharge port and effectively increasing the initial velocity of the material 1 when it moves to the second loading conveyor belt 822.

[0056] In some embodiments, the second loading conveyor belt 822 has a third track plate 8221 and a fourth track plate 8222 arranged in parallel, and there is a gap slightly larger than the outer diameter of the material 1 between the third track plate 8221 and the fourth track plate 8222 to form a channel for transporting the material 1. The third track plate 8221 and the fourth track plate 8222 can reduce the risk of the material 1 falling to the outside of the second loading conveyor belt 822 during transportation.

[0057] Furthermore, the feeding ends of the third track plate 8221 and the fourth track plate 8222 pass through the second discharge port and extend to the diameter position on the transfer bottom plate 8511 that is perpendicular to the second loading conveyor belt 822, wherein the third track plate 8221 is farther from the axis of the transfer tray 851 than the fourth track plate 8222, and the end of the third track plate 8221 extending into the transfer tray 851 is provided with a third guide plate 8223, and / or the end of the fourth track plate 8222 extending into the transfer tray 851 is provided with a fourth guide plate 8224; the third guide plate 8223 and / or the fourth guide plate 8224 form an open structure at the passage where the material 1 enters between the third track plate 8221 and the fourth track plate 8222, thereby achieving a guiding effect on the material 1.

[0058] Continue to refer to Figure 1 and Figure 2As shown, the third guide plate 8223 is rotatably connected to the third track plate 8221, and the third guide plate 8223 has an opening position and a closing position. When the third guide plate 8223 is located at the opening position, the third guide plate 8223 has an open structure at the channel opening, and when the third guide plate 8223 is located at the closing position, the third guide plate 8223 blocks the channel opening and is used to prevent material 1 from entering the channel; and / or, the fourth guide plate 8224 is rotatably connected to the fourth track plate 8222, and the fourth guide plate 8224 has an opening position and a closing position. When the fourth guide plate 8224 is located at the opening position, the fourth guide plate 8224 has an open structure at the channel opening, and when the fourth guide plate 8224 is located at the closing position, the fourth guide plate 8224 blocks the channel opening and is used to prevent material 1 from entering the channel.

[0059] Optionally, step S1 also includes: the second feeding conveyor belt 822 first conveys the material 1 to the partition component, the partition component conveys all the materials 1 to the feeding space in sequence, and the material 1 in the feeding space is then driven by the second feeding conveyor belt 822 to move to the corresponding feeding station.

[0060] Furthermore, based on the above-mentioned separation component, the continuous materials 1 can be adjusted to have a set interval and maintain the set gap to avoid the distance between two materials 1 being too small, which affects the regular movement before pushing the materials.

[0061] Continue to refer to Figure 1 and Figure 2 As shown, the partition assembly includes a partition shaft 841 and a partition plate 842, and a plurality of partition plates 842 are evenly arranged on the circumferential side of the partition shaft 841, and a partition space for accommodating a material 1 is formed between every two partition plates 842. The partition plate 842 can be a plate-like structure or a stick-like structure, etc., as long as it can provide thrust and resistance to the material 1 to separate two adjacent materials 1. The partition shaft 841 is rotatably set at the position where the pushing mechanism receives the material 1, and the partition shaft 841 extends in the vertical direction; the pushing mechanism includes a pushing block 101, and a pushing guide surface 1011 is formed at the end of the pushing block 101 facing the partition assembly, and the pushing guide surface 1011 and the partition space are surrounded together. A feeding space is formed; wherein, a driving motor can be provided on the partition shaft 841 to realize active rotation, and the partition shaft 841 can also realize rotation when the partition plate 842 is pushed by the material 1. The material 1 first contacts one of the partition plates 842, and the material 1 pushes the partition plate 842 under the transportation of the second feeding conveyor belt 822, thereby driving the partition shaft 841 to rotate, and the partition plate 842 located on the rear side of the material 1 begins to move between the material 1 and the next material 1, thereby isolating the material 1 in the separation space formed between the two partition plates 842, and the partition shaft 841 continues to rotate, and the opening of the separation space is set toward the pushing guide surface 1011, and together they form a feeding space.

[0062] Furthermore, based on the above-mentioned separation assembly, the materials 1 can be moved to the loading station one by one, thereby avoiding the accumulation of the materials 1 at the position of the pushing mechanism.

[0063] In some embodiments, a plurality of pushing grooves 1012 are evenly arranged along the second direction on the pushing block 101, and the shape of each pushing groove 1012 matches the shape of the side wall of the material 1. Furthermore, each pushing groove 1012 covers the circumferential side of the material 1 within a range of no more than 180 degrees, so that the material 1 can enter the opening of the pushing groove 1012 and leave the pushing groove 1012, and continue to be transported by the filling conveyor belt 11.

[0064] In a further embodiment, the connection between every two adjacent push grooves 1012 is separated by a sharp corner or a rounded corner structure. When the push groove 1012 moves toward the material 1, if there is a certain deviation between the material 1 and the push groove 1012, the material 1 can be guided to the correct position through the sharp corner or the rounded corner to ensure that the material 1 can move accurately to the bottom of the push groove 1012 (the side opposite to the opening). It should be understood that a guide structure formed by a sharp corner or a rounded corner is also provided between the push guide surface 1011 and the adjacent push groove 1012.

[0065] Optionally, step S4 further includes: the clamping mechanism 3 rises to a set height before the material 1 reaches directly below the filling port 41, and when the material 1 reaches directly below the filling port 41, the in-place sensor 32 detects that the material 1 moves to the filling station. Specifically, the detection end of the in-place sensor 32 can be arranged opposite to the filling port 41 in the second direction, and the in-place sensor 32 can also be spaced apart from the filling port 41 in the first direction by a distance of half the width of the material 1 in the first direction. As long as it can be detected that the center position of the opening at the top of the material 1 is displaced to directly below the filling port 41, at this time , the two clamping arms 31 in the clamping mechanism 3 begin to descend and are respectively located on both sides of the material 1, and the two clamping arms 31 then begin to approach each other to clamp and fix the material 1, and then lift the material 1 to a position close to the filling port 41; it should be understood that after the clamping mechanism 3 rises to the set height, it will not interfere with the conveying action of the material 1 on the filling conveyor belt 11 of the filling line, that is, the bottom of the clamping mechanism 3 will be higher than the top of the material 1. It should be noted that the distance between the filling port 41 and the filling conveyor belt 11 is greater than the height of the two materials 1 in the vertical direction.

[0066] Furthermore, based on the above-mentioned clamping mechanism 3, the material 1 can be regulated and fixed before filling, and the material 1 can be moved away from the filling conveyor belt 11 to avoid the filling conveyor belt 11 affecting the filling of the material 1. The clamping mechanism 3 can also drive the material 1 to approach the filling port 41, so that the filling effect of the material 1 is better and the splashing of the filling material is reduced.

[0067] Optionally, step S4 also includes: before the two clamping arms 31 approach each other to prepare to clamp the material 1, the two clamping arms 31 are first rotated by a certain angle so that the tops of the clamping grooves 311 on the two clamping arms 31 first contact the outer wall of the material 1, and when the clamping grooves 311 on both sides are against the outer wall of the material 1, the two clamping arms 31 continue to apply a clamping force to the material 1, and the two clamping arms 31 rotate themselves and utilize the friction force with the outer wall of the material 1 to lift the material 1 to the filling conveyor belt 11 that leaves the filling line. It should be noted that the rotation directions of the two clamping arms 31 are opposite.

[0068] Furthermore, based on the above-mentioned clamping mechanism 3, the two clamping arms 31 will achieve alignment of the material 1 with the filling port 41 while approaching each other. After the two clamping arms 31 clamp the material 1, the contact area between the two and the outer wall of the material 1 is very small (only the top part of the clamping groove 311 is in contact with the material 1), thereby reducing the friction of the two clamping arms 31 on the outer wall of the material 1. After clamping the material 1, the contact area between the clamping arms 31 and the material 1 is gradually increased by rotating the clamping arms 31, thereby reducing the friction effect on the material 1 caused by the uneven heights of the clamping arms 31 on both sides. When the two clamping arms 31 rotate, the contact position with the material 1 is continuously rising, thereby driving the material 1 to gradually rise and making the material 1 separate from the filling conveyor belt 11, thereby avoiding the shaking and vibration of the filling conveyor belt 11 itself from affecting the filling work.

[0069] Continue to refer to Figure 4 and Figure 5 As shown, the clamping groove 311 matches the side wall shape of the material 1. The clamping groove 311 can specifically be a semicircular groove, thereby increasing the contact area with the side wall of the material 1 and improving the clamping stability; further, an anti-slip pad can be provided in the clamping groove 311, thereby further improving the contact surface roughness between the clamping arm 31 and the material 1, thereby improving the clamping stability and reliability of the clamping arm 31 on the material 1.

[0070] In a further embodiment, the clamping groove 311 covers a range of less than 180 degrees on the circumferential side of the material 1, so that the two clamping arms 31 can have a set interval between each other after clamping the material 1, thereby avoiding interference between the two clamping arms 31 and affecting the clamping reliability of the material 1; specifically, the clamping groove 311 can cover 100 to 160 degrees on the circumferential side of the material 1, which can ensure that the contact surface between the clamping groove 311 and the material 1 is large enough and avoid interference between the two clamping arms 31.

[0071] In some embodiments, the height of the clamping arm 31 is less than the height of the material 1, and the clamping arm 31 is used to clamp the area between the top and bottom of the material 1, that is, to clamp the middle part of the material 1. This arrangement can avoid interference with the filling conveyor belt 11 when the clamping arm 31 descends, and can also avoid interference with the bottom of the filling tank 4 when the clamping arm 31 rises. Furthermore, the height of the clamping arm 31 is greater than 2 / 3 of the height of the material 1, thereby ensuring the stability and reliability of the clamping arm 31 in clamping the material 1.

[0072] Continue to refer to Figure 4 and Figure 5 As shown, the clamping mechanism 3 also includes a clamping frame 36, wherein the clamping frame 36 is provided with a lifting assembly 33, a translation assembly 34 and a rotation assembly 35, the ends of the two clamping arms 31 are respectively connected to the two rotation assemblies 35, the rotation axis of the rotation assembly 35 is arranged parallel to the second direction, so as to drive the clamping arms 31 connected thereto to rotate around the rotation axis parallel to the second direction, the translation assembly 34 is connected to the clamping frame 36 through the lifting assembly 33, and the lifting assembly 33 is used to drive the translation assembly 34 on the clamping frame 36 along the vertical direction (third direction) The translation assembly 34 is used to drive the two rotating assemblies 35 to reciprocate along the first direction, thereby driving the clamping arm 31 to approach or move away from the filling port 41. The translation assembly 34 is used to drive the two rotating assemblies 35 to reciprocate along the first direction, wherein the translation assembly 34 may include two translation blocks 341, and the two rotating assemblies 35 are correspondingly arranged on the two translation blocks 341. The translation assembly 34 can drive the two translation blocks 341 to reciprocate along the first direction, thereby driving the rotating assembly 35 and the clamping arm 31 to reciprocate in the first direction, and the two translation blocks 341 can perform synchronous or asynchronous motion.

[0073] In some embodiments, a clamping chamfer 3111 is provided at the top of the clamping groove 311, and the clamping chamfer 3111 can be an oblique structure. When the clamping arm 31 rotates a certain angle (the tops of the two clamping grooves 311 are close to each other, and the bottoms of the two clamping grooves 311 are away from each other), the two clamping arms 31 can utilize the inclined surface formed by the clamping chamfer 3111 to make surface contact with the side wall of the material 1. Furthermore, the clamping chamfer 3111 smoothly transitions to the side wall of the lower part of the clamping groove 311 through the arc-shaped clamping fillet 3112. Through the setting of the clamping fillet 3112, after the clamping arm 31 clamps and fixes the material 1 using the clamping chamfer 3111, that is, when the translation assembly 34 and the rotation assembly 35 drive the two clamping arms 31 to approach each other and perform a rotation action in the opposite direction to the previous direction, the clamping fillet 3112 can be used to make the relative position of the material 1 and the clamping groove 311 change smoothly, and the whole process is smoother.

[0074] Continue to refer to Figure 7 and Figure 8 As shown, the filling line also includes a cleaning mechanism 9, which is arranged within the coverage of at least one heating mechanism 2, that is, each heating mechanism 2 may be provided with a cleaning mechanism 9, or only one or more heating mechanisms 2 may be provided with a cleaning mechanism 9, the cleaning mechanism 9 includes a cleaning member 91, a cleaning seat 92, a first elastic member 931 and a cleaning track 94, the cleaning member 91 is arranged on the cleaning seat 92, and contacts the bottom surface of the filling conveyor belt 11 in the filling line, and the cleaning member 91 is a brush, a scraper The structure can be used as long as the outer surface of the filling conveyor belt 11 can be scraped. The bottom surface of the filling conveyor belt 11 here refers to the outer surface of the upper half of the annular filling conveyor belt 11 when it continues to rotate to the lower half after completing the conveying of the material 1. The cleaning seat 92 is slidably arranged on the cleaning track 94 along the movement direction of the filling conveyor belt 11. The two ends of the first elastic member 931 are respectively connected to the cleaning seat 92 and the cleaning track 94, and are used to provide the cleaning seat 92 with an elastic force that is the same as or opposite to the movement direction of the filling conveyor belt 11.

[0075] Furthermore, based on the above-mentioned cleaning mechanism 9, not only can the outer surface of the filling conveyor belt 11 be cleaned, but also the temperature of the heating mechanism 2 can be used to heat and soften the filling material on the filling conveyor belt 11, so that the cleaning mechanism 9 can be more convenient to scrape the filling material, and it is easier to make the filling material separate from the filling conveyor belt 11, thereby improving the cleaning efficiency of the cleaning mechanism 9; through the setting of the first elastic member 931, the thrust of the cleaning member 91 pushed by the filling conveyor belt 11 can be coordinated, so that the cleaning member 91 can continuously reciprocate in the first direction or the opposite direction, thereby improving the cleaning effect, and the cleaning mechanism 9 not only does not require a power source, but also can use the heating effect of the heating mechanism 2 on the filling conveyor belt 11 to improve the cleaning effect of the cleaning mechanism 9, and does not occupy additional space.

[0076] Optionally, the cleaning mechanism 9 also includes a second elastic member 932 and a cleaning slider 95. The cleaning slider 95 is slidably set on the cleaning seat 92 along the movement direction of the filling conveyor belt 11. Multiple cleaning sliders 95 are evenly arranged on the cleaning seat 92. The second elastic member 932 is set between every two adjacent cleaning sliders 95 and is used to provide the cleaning slider 95 with an elastic force that is the same or opposite to the movement direction of the filling conveyor belt 11.

[0077] Furthermore, based on the above-mentioned cleaning mechanism 9, through the cooperation of the first elastic member 931, the second elastic member 932, the cleaning slider 95, the cleaning seat 92 and the cleaning track 94, after the cleaning member 91 is subjected to the thrust of the filling conveyor belt 11, the cleaning member 91 located at the end along the movement direction moves to the extreme position in the first direction. At this time, all the cleaning members 91 at the rear drive the cleaning slider 95 below to begin to squeeze or stretch the second elastic member 932 on its front side, and the cleaning seat 92 also begins to squeeze or stretch the first elastic member 931. Through the joint action of multiple first elastic members 931 and multiple second elastic members 932, combined with the unstable thrust of the filling conveyor belt 11 on the cleaning member 91, a double shaking effect can be created. By utilizing the frequent shaking of multiple cleaning members 91, the cleaning effect of the cleaning mechanism 9 on the filling conveyor belt 11 can be significantly improved.

[0078] Optionally, the cleaning mechanism 9 also includes a tensioning assembly, which includes a plurality of tensioning rollers 96 supported on the inner surface and / or outer surface of the filling conveyor belt 11, wherein two adjacent tensioning rollers 96 are supported on the inner surface of the filling conveyor belt 11 to form a cleaning area, and the cleaning member 91 contacts the outer surface of the filling conveyor belt 11 located in the cleaning area.

[0079] Furthermore, based on the above-mentioned tensioning assembly, at least two tensioning rollers 96 extending along the second direction can be used to tension the filling conveyor belt 11, so that the filling conveyor belt 11 corresponding to the cleaning mechanism 9 is in a tensioned state, thereby further ensuring that all cleaning parts 91 can be cleaned reliably and evenly, thereby improving the cleaning effect of the filling conveyor belt 11.
