Description

Technical Field

[0001] This utility model relates to the field of coating equipment technology, specifically a coating device for aquatic feed additive packaging line. Background Technology

[0002] Feed additives refer to small or trace amounts of substances added during feed production, processing, and use. Feed additives are essential raw materials in the modern feed industry, significantly enhancing the nutritional value of basic feeds, improving animal production performance, ensuring animal health, saving feed costs, and improving the quality of livestock products. After production, feed additives need to be packaged using packaging machines. The bagged feed additives are transferred via conveyor belts and stacked. Because the bags are prone to slipping, the stacked feed additive bags are easily collapsed, hindering stacking and potentially causing injury to production workers. Therefore, it is necessary to apply an adhesive to the top of the packaged feed additive bags to ensure a certain adhesive bond between adjacent bags.

[0003] According to a search report from a novelty search agency, CN216910779U discloses a gluing device for a feed additive packaging line. The device includes a vertical plate fixed to a conveyor belt support, a fixed seat on the vertical plate, and a gluing roller rotatably mounted above the conveyor belt via a connecting frame. A fixed shell is mounted on the connecting frame, and a gluing nozzle is mounted on the fixed shell. The outlet of the gluing nozzle is located above the gluing roller. A height adjustment component is provided between the fixed seat and the fixed shell to adjust the height of the gluing roller. The feed additive bags are connected to the gluing roller via the conveyor belt. The gluing roller adheres the glue to the feed additive bags. The height adjustment component allows for adjustment of the gluing roller's height to accommodate different sizes of feed additive bags. The glue-coated feed additive bags are less prone to collapse during stacking, improving stacking stability.

[0004] The above-disclosed technology discloses a gluing device for a feed additive packaging line. This device applies glue to the top of the feed additive bags by using gluing rollers that rotate and rub against the bags during transport. The glue-adhered surface of the feed additive bags makes them less prone to collapse during stacking, improving stacking stability. However, it still has the following shortcomings in use:

[0005] 1. Even for feed additive bags of the same specification, slight deviations in thickness are inevitable after filling. These slight deviations can cause the bags to bulge and become jammed against the coating rollers. The lack of an adaptive, elastic anti-jamming structure makes its applicability unsatisfactory. 2. The lack of an automatic cleaning and dust removal mechanism for the top of the feed additive bags before coating means that residual dust on the top of the bags can affect the coating effect. Therefore, this application proposes a coating device for aquatic feed additive packaging lines to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of this invention is to provide a coating device for aquatic feed additive packaging line to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gluing device for aquatic feed additive packaging line, comprising a belt conveyor and a U-shaped vertical plate fixed between the front and rear sides of the belt conveyor. A lifting vertical guide assembly is installed on the U-shaped vertical plate. A U-shaped seat is provided on the left side of the U-shaped vertical plate. A gluing roller is rotatably installed between the front and rear inner walls of the U-shaped seat. A protective cover is fixedly fitted on the outer side of the U-shaped seat. The gluing roller is located inside the protective cover. Two vertical missile support assemblies are fixedly connected to the top of the U-shaped seat to provide vertical guidance and elastic support. The lifting vertical guide assembly is slidably fitted on the two vertical missile support assemblies. The lifting vertical guide assembly is used to adjust the vertical guidance of the vertical missile support assembly. The vertical missile support assembly is used to drive the gluing roller to adjust the vertical guidance through the U-shaped seat during the adjustment, so as to apply glue to the top of feed additive bags of different heights, and to perform adaptive elastic avoidance and anti-jamming when there is a height deviation when multiple feed additives are conveyed sequentially.

[0008] The protective cover is equipped with a secondary blowing and brushing dust removal assembly located on the left side of the coating roller for secondary blowing and brushing cleaning. A glue-passing assembly is installed on the U-shaped seat for passing glue onto the coating roller. The secondary blowing and brushing dust removal assembly is used to blow and brush the top of the feed additive bag twice during the conveying process. The glue-passing assembly is used to supply glue to the top of the coating roller after connecting to an external glue supply device. The coating roller rotates due to the friction caused by the conveying of the feed additive bag, thus performing the rotating glue application work.

[0009] Preferably, the lifting vertical guide assembly includes an L-shaped lifting plate, and the U-shaped vertical plate is slidably sleeved on the L-shaped lifting plate. An electric telescopic rod with its extended end fixedly connected to the inner wall of the top of the L-shaped lifting plate is fixedly installed on the left side of the U-shaped vertical plate. The L-shaped lifting plate and the electric telescopic rod cooperate to drive the L-shaped lifting plate to move up and down for lifting operations.

[0010] Preferably, the vertical missile support assembly includes a T-shaped guide rod fixedly connected to the top of the U-shaped seat, and the L-shaped lifting plate slidably sleeved on the two T-shaped guide rods. A fixing sleeve is fixedly sleeved on each T-shaped guide rod, and a spring is fixedly connected between the top of the fixing sleeve and the inner top wall of the L-shaped lifting plate. The spring is movably sleeved on the corresponding T-shaped guide rod. The T-shaped guide rods, fixing sleeves, and springs work together to sequentially drive the U-shaped seat to rise and fall via the two springs, two fixing sleeves, and two T-shaped guide rods when the L-shaped lifting plate rises and falls. The U-shaped seat then drives the adhesive rollers to rise and fall, allowing feed additives of different thicknesses to be applied. The height of the feed bag is adjusted. In addition, when there is a slight height difference between feed additive bags of the same specification and batch, the protruding part of the feed additive bag squeezes and drives the coating roller to rotate as friction drives it to move slightly upward. The coating roller drives the U-shaped seat to move upward. The U-shaped seat drives two fixed sleeves through two T-shaped guide rods to compress two springs. After passing through the protruding part, the elastic force of the compressed springs rebounds and resets. This achieves an adaptive elastic avoidance and anti-jamming effect when multiple feed additive bags are conveyed sequentially with height differences, further improving applicability.

[0011] Preferably, the two-brush dust removal assembly includes a hollow brush plate fixedly installed on the left side of the baffle cover. Multiple soft bristles are fixedly arranged at the bottom of the hollow brush plate. Multiple first cleaning pipes, all inclined downwards to the left, are evenly spaced and fixedly connected to the bottom left side of the hollow brush plate. A powerful fan is fixedly installed on the left side of the baffle cover. The bottom of the powerful fan is an air outlet and is fixedly connected to the top of the hollow brush plate. A vent pipe is fixedly connected to the right side of the hollow brush plate. The right end of the vent pipe extends into the baffle cover and is fixedly connected to a circular pipe with sealed front and rear ends. Multiple L-shaped cleaning pipes are evenly spaced and fixedly connected to the bottom of the circular pipe. The bottom ends of the L-shaped cleaning pipes are inclined towards the bottom of the soft bristles. The system, consisting of a plate, soft brush bristles, a first cleaning pipe, a powerful blower, a ventilation pipe, a round pipe, and an L-shaped cleaning pipe, works in conjunction with each other. During the transport of feed additive bags, the powerful blower supplies air into the hollow brush plate. A portion of the air is blown downwards and to the left through multiple first cleaning pipes, while another portion is introduced into the round pipe through the ventilation pipe and then blown downwards and to the left through multiple L-shaped cleaning pipes. During transport, the top of the feed additive bag is first cleaned by the first cleaning pipe, then brushed by the soft brush bristles, and subsequently cleaned again by the L-shaped cleaning pipes. This achieves the effect of double cleaning and brushing of the top of the feed additive bag during transport, preventing excessive impurities from remaining on the top and affecting the adhesive coating effect, thus improving the overall performance.

[0012] Preferably, the glue-feeding assembly includes a horizontal tube fixedly connected to the top of the U-shaped seat, with both the front and rear ends being sealed structures. The bottom of the horizontal tube is connected to and fixedly connected to multiple glue-applying nozzles, the bottom of which extends into the U-shaped seat and is located above the glue-applying roller. The left side of the horizontal tube is connected to and fixedly connected to an injection connector. The horizontal tube, glue-applying nozzles, and injection connector cooperate with each other. The injection connector is connected to an external glue supply device to feed glue into the horizontal tube. The glue is discharged through the multiple glue-applying nozzles to the top of the glue-applying roller. Under the rotation of the glue-applying roller, the glue is supplied to the outside of the glue-applying roller.

[0013] Preferably, the bottom of the glue-applying roller is lower than the bottom of the guard, and the bottom of the glue-applying roller is flush with the bottom of the soft bristles.

[0014] Preferably, a rectangular guide hole is provided on the top inner wall of the U-shaped vertical plate to slide and fit with the outer side of the L-shaped lifting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. By using a belt conveyor, guardrail, and dual-blow dust removal assembly, the top of the feed additive bag can be pre-cleaned twice by blowing and brushing to remove dust during transport, thus avoiding the phenomenon that too much dust and impurities remain on the top and affect the coating effect, thereby improving the performance.

[0017] 2. By combining the lifting vertical guide assembly, vertical missile support assembly, U-shaped seat, glue coating rollers, and U-shaped upright plate, the glue coating height can be adjusted according to feed additive bags of different specifications and thicknesses, thus improving applicability;

[0018] 3. Through the combination of the vertical missile support assembly, U-shaped seat and glue-through assembly, glue can be applied to the top of the feed additive bag during the conveying process, and adaptive elastic avoidance can be achieved to prevent jamming when there are height deviations among multiple feed additive bags, further improving applicability.

[0019] This utility model incorporates a series of structures that facilitate pre-cleaning and brushing the top of feed additive bags twice during transport to remove dust. This prevents residual dust and impurities from affecting the adhesive coating effect, thus improving performance. It also allows for adjusting the adhesive coating height according to feed additive bags of different thicknesses, facilitates adhesive coating on the top of the bags during transport, and provides adaptive elastic avoidance to prevent jamming when multiple feed additive bags have different heights, further enhancing applicability.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figures 1 to 3 As shown in this embodiment, a gluing device for an aquatic feed additive packaging line includes a belt conveyor 100 and a U-shaped vertical plate 1 fixed between the front and rear sides of the belt conveyor 100. A lifting vertical guide assembly is installed on the U-shaped vertical plate 1. A U-shaped seat 2 is provided on the left side of the U-shaped vertical plate 1. A gluing roller 201 is rotatably installed between the front and rear inner walls of the U-shaped seat 2. A support shaft is fixedly connected between the front and rear inner walls of the U-shaped seat 2. A circular through hole is opened on the front side of the gluing roller 201. Two bearings are fixedly sleeved in the circular through hole. The inner ring of the bearing is fixedly sleeved with the outer side of the support shaft, which achieves the effect of rotating the gluing roller 201. A protective cover 202 is fixedly fitted on the outer side of the U-shaped seat 2. The glue-applying roller 201 is located inside the protective cover 202. Two vertical guide components are fixedly connected to the top of the U-shaped seat 2 to provide vertical guidance and elastic support. The lifting vertical guide component is slidably fitted on the two vertical guide components. The lifting vertical guide component is used to adjust the vertical guide lifting of the vertical guide component. The vertical guide component is used to drive the glue-applying roller 201 to adjust the lifting during the lifting adjustment, so as to apply glue to the top of feed additive bags of different heights, and to perform adaptive elastic avoidance and prevent jamming when there is a height deviation when multiple feed additives are conveyed sequentially.

[0026] The protective cover 202 is equipped with a secondary blowing and brushing dust removal assembly located on the left side of the coating roller 201 for secondary blowing and brushing. The U-shaped seat 2 is equipped with a glue-passing assembly for passing glue onto the coating roller 201. The secondary blowing and brushing dust removal assembly is used to blow and brush the top of the feed additive bag twice during the conveying process. The glue-passing assembly is used to supply glue to the top of the coating roller 201 after connecting to an external glue supply device. The coating roller 201 rotates due to friction from the conveying of the feed additive bag, thus performing the rotating glue application work.

[0027] Specifically, the lifting vertical guide assembly includes an L-shaped lifting plate 101 and a U-shaped vertical plate 1 slidably fitted onto the L-shaped lifting plate 101. The top inner wall of the U-shaped vertical plate 1 has a rectangular guide hole that slides onto the outer side of the L-shaped lifting plate 101, which serves to guide the vertical sliding of the L-shaped lifting plate 101. An electric telescopic rod 102 with its extended end fixedly connected to the top inner wall of the L-shaped lifting plate 101 is fixedly installed on the left side of the U-shaped vertical plate 1. The L-shaped lifting plate 101 and the electric telescopic rod 102 cooperate to drive the L-shaped lifting plate 101 to move up and down for lifting operations.

[0028] Furthermore, the vertical missile support assembly includes a T-shaped guide rod 3 fixedly connected to the top of the U-shaped base 2, and an L-shaped lifting plate 101 slidably sleeved on the two T-shaped guide rods 3. The top of the L-shaped lifting plate 101 has two vertical guide holes that slide and fit onto the outer sides of the corresponding T-shaped guide rods 3, providing vertical sliding guidance for the T-shaped guide rods 3. A fixing sleeve 301 is fixedly sleeved on the T-shaped guide rod 3, and a spring 302 is fixedly connected between the top of the fixing sleeve 301 and the inner top wall of the L-shaped lifting plate 101. The spring 302 is movably sleeved on the corresponding T-shaped guide rod 3. The T-shaped guide rods 3, fixing sleeves 301, and springs 302 work together to guide the L-shaped lifting plate 101 upwards and downwards, sequentially through the two springs 302, the two fixing sleeves 301, and the two T-shaped guide rods 3. The U-shaped seat 2 rises and falls, driving the glue-coating roller 201 to adjust the glue-coating height according to the different specifications and thicknesses of the feed additive bags. Additionally, when there is a slight height deviation among feed additive bags of the same specification and batch, the protruding part of the feed additive bag, driven by friction, compresses and drives the glue-coating roller 201 to move slightly upward. The glue-coating roller 201 then drives the U-shaped seat 2 upward. The U-shaped seat 2, through two T-shaped guide rods 3, drives two fixed sleeves 301 to compress two springs 302. After passing through the protruding part, the springs 302, in their compressed state, rebound and reset. This achieves an adaptive elastic avoidance and anti-jamming effect when multiple feed additive bags are conveyed sequentially with height deviations, further improving applicability.

[0029] Furthermore, the second-stage dust removal assembly includes a hollow brush plate 501 fixedly installed on the left side of the baffle 202. Multiple soft bristles 502 are fixedly arranged on the bottom of the hollow brush plate 501. The bottom of the adhesive roller 201 is lower than the bottom of the baffle 202, and the bottom of the adhesive roller 201 is flush with the bottom of the soft bristles 502. Multiple first-stage cleaning pipes 503, all inclined downwards to the left, are evenly spaced and fixedly connected to the bottom left side of the hollow brush plate 501. A powerful fan 5 is fixedly installed on the left side of the shield 202. The bottom of the powerful fan 5 is an air outlet and is connected and fixed to the top of the hollow brush plate 501. A vent pipe 504 is fixedly connected to the right side of the hollow brush plate 501. The right end of the vent pipe 504 extends into the shield 202 and is connected and fixed to a round pipe 505 with sealed front and rear ends. Multiple L-shaped cleaning pipes 506 are fixedly connected at equal intervals at the bottom of the round pipe 505. The bottom end is inclined towards the bottom of the soft brush bristles 502. The hollow brush plate 501, soft brush bristles 502, first cleaning pipe 503, powerful fan 5, ventilation pipe 504, round pipe 505 and L-shaped cleaning pipe 506 work together. When the feed additive bag is conveyed, the powerful fan 5 is activated to supply air into the hollow brush plate 501. Part of the air is blown out to the lower left through multiple first cleaning pipes 503, and another part of the air is introduced into the round pipe 505 through the ventilation pipe 504, and then blown out to the lower left through multiple L-shaped cleaning pipes 506. During the conveying of the feed additive bag, the top of the bag is first cleaned by the first cleaning pipe 503, then brushed by the soft brush bristles 502, and then the brushed part is cleaned again by the L-shaped cleaning pipes 506. This achieves the effect of cleaning the top of the feed additive bag twice by blowing and brushing during the conveying process, avoiding the phenomenon that too many impurities remain on the top and affect the coating effect, thus improving the use effect.

[0030] Furthermore, the glue-feeding assembly includes a horizontal tube 4 fixedly connected to the top of the U-shaped seat 2, with both the front and rear ends being sealed structures. Multiple glue-applying nozzles 401 are fixedly connected to the bottom of the horizontal tube 4. The bottom of the glue-applying nozzles 401 extends into the U-shaped seat 2 and is located above the glue-applying roller 201. A glue-injection connector is fixedly connected to the left side of the horizontal tube 4. The horizontal tube 4, glue-applying nozzles 401, and glue-injection connector are configured to cooperate. The glue-injection connector is connected to an external glue supply device to feed glue into the horizontal tube 4. The glue is discharged through the multiple glue-applying nozzles 401 to the top of the glue-applying roller 201. Under the rotation of the glue-applying roller 201, glue is supplied to the outside of the glue-applying roller 201.

[0031] The usage method of this embodiment is as follows: When using the coating device for the aquatic feed additive packaging line, firstly, adjust the height of the coating roller 201 according to the thickness of the feed additive bag. During adjustment, start the electric telescopic rod 102 to drive the L-shaped lifting plate 101 to move up or down. The L-shaped lifting plate 101 drives the U-shaped seat 2 to rise and fall in sequence through two springs 302, two fixing sleeves 301, and two T-shaped guide rods 3. The U-shaped seat 2 drives the coating roller 201 to rise and fall, adjusting the coating height according to the feed additive bags of different specifications and thicknesses. After the adjustment is appropriate, the feed additive bag is conveyed to the right by the belt conveyor 100. The powerful blower 5 supplies air into the hollow brush plate 501. Part of the air is blown out to the lower left through multiple first cleaning pipes 503, and another part of the air is introduced into the round pipe 505 through the ventilation pipe 504, and then blown out to the lower left through multiple L-shaped cleaning pipes 506. During the conveying of the feed additive bag, its top is first blown clean by the first cleaning pipe 503, and then brushed clean by the soft bristles 502. Immediately afterwards, the brushed part is blown clean again by the L-shaped cleaning pipes 506. This achieves the effect of blowing and brushing clean the top of the feed additive bag twice during the conveying process, avoiding the phenomenon that too much dust and impurities remain on the top and affect the coating effect, thus improving the use effect.

[0032] Connect the glue injection connector to an external glue supply device to inject glue into the horizontal tube 4. The glue is discharged through multiple glue nozzles 401 to the top of the glue coating roller 201. When the feed additive bag is conveyed to the glue coating roller 201, friction drives the glue coating roller 201 to rotate. Under the action of the rotation of the glue coating roller 201, the glue is supplied to the outside of the glue coating roller 201 through the glue nozzles 401, and the glue coating work is performed on the top of the feed additive bag under the action of the rotation of the glue coating roller 201. In addition, when there is a slight height deviation in feed additive bags of the same specification and batch, the feed... When the feed additive bag rotates on the friction-driven coating roller 201, its protruding part squeezes and drives the coating roller 201 to move slightly upward. The coating roller 201 drives the U-shaped seat 2 to move upward. The U-shaped seat 2 drives the two fixed sleeves 301 to compress the two springs 302 through the two T-shaped guide rods 3. After passing through the protruding part, the spring force of the compressed spring 302 rebounds and resets, realizing the effect of adaptive elastic avoidance and anti-jamming when multiple feed additive bags are conveyed in sequence with height deviation, further improving applicability.
