Description

Technical Field

[0001] The present invention relates to the technical field of food packaging, and particularly to an intubation device.

Background Art

[0002] In recent years, the food processing industry has developed rapidly, and the market share of various boxed products (including cup-shaped ones) has been continuously increasing, especially in the aspects of drinks such as yogurt, jelly, turtle jelly, and milk. Boxed products usually place 6 to 12 small boxes of drinks in each packaging box according to specific requirements. These drinks usually need straws for consumption. The traditional method is that after the packaging box is sealed, the packaging box is conveyed out through a conveying chain, and then the corresponding number of continuous straws is inserted into the gap between two rows of drinks through an intubation device. The existing intubation device includes a straw conveying block installed on the conveyor belt and a push rod assembly. The straw conveying block has a receiving groove for holding straws, and the push rod assembly is used to push out the continuous straws in the straw conveying block so that the continuous straws are inserted into the gap. In order to avoid the interference of the straw conveying block with the conveyance of the packaging box, the straw conveying block is always located outside the packaging box and the distance between the straw conveying block and the packaging box remains unchanged during conveyance. In addition, there is a certain distance between the drink and the edge of the box opening. In this way, when the push rod assembly pushes the continuous straws, one end of the continuous straws extending out of the receiving groove will spread out before being inserted into the gap, and the continuous straws with a larger spreading amplitude will be blocked by the cup body of the drink and cannot be inserted into the gap, resulting in the phenomenon of missed insertion of straws.

Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an intubation device that can ensure that the continuous straws are inserted into the gap in a closely arranged stacked state, effectively avoiding the occurrence of the phenomenon of missed insertion of straws and ensuring the packaging qualification rate.

[0004] To solve the above technical problem, the present invention adopts the following technical solutions:

[0005] An intubation device includes a frame, and also includes two synchronously moving conveyor belts, a bracket, a push rod assembly, and a straw conveying block mounted on the frame. The straw conveying block has a receiving groove for holding straws. The bracket includes a sliding rod extending perpendicular to the conveying direction, and both ends of the sliding rod are fixed on the two conveyor belts respectively. The straw conveying block and the push rod assembly are slidably mounted on the sliding rod. A guiding assembly is further provided between the two conveyor belts. The guiding assembly includes a first guiding member slidably engaged with the straw conveying block and a second guiding member slidably engaged with the push rod assembly. The first guiding member includes a docking section for abutting the straw conveying block against the body of the drink cup or inserting it into the gap, and a disengaging section for moving the straw conveying block away from the packaging box. The second guiding member includes an insertion section, one end of the insertion section is away from the docking section, and the other end extends along the conveying direction and gradually approaches the docking section. When the push rod assembly cooperates with the other end, the straw in the receiving groove is pushed into the packaging box.

[0006] In the above intubation device, the guiding assembly further includes an upper guiding plate and a lower guiding plate fixed on the frame. The docking section and the insertion section are provided on the upper guiding plate, a part of the disengaging section is provided on the lower guiding plate, and the docking section and the disengaging section are connected end to end. The second guiding member further includes a reset section for resetting the push rod assembly, a part of the reset section is provided on the lower guiding plate, and the reset section and the insertion section are connected end to end.

[0007] In the above intubation device, the guiding assembly further includes a first guiding wheel and a second guiding wheel. One first guiding wheel is provided between the two ends of the upper guiding plate and the lower guiding plate respectively, and a part of the disengaging section is provided on the circumference of the first guiding wheel. One second guiding wheel is provided between the two ends of the upper guiding plate and the lower guiding plate respectively, and a part of the reset section is provided on the circumference of the second guiding wheel.

[0008] In the above intubation device, the intubation device further includes a motor, a first rotating shaft and a second rotating shaft rotatably mounted at both ends of the frame, two driving wheels fixed on the first rotating shaft, and two driven wheels fixed on the second rotating shaft. One of the conveyor belts is sleeved on one of the driving wheels and one of the driven wheels, and the other conveyor belt is sleeved on the other driving wheel and the other driven wheel. The first rotating shaft is connected to the motor. One of the first guiding wheel and the second guiding wheel is fixed on the first rotating shaft, and the other first guiding wheel and the second guiding wheel are fixed on the second rotating shaft.

[0009] In the above intubation device, the guiding assembly further includes two arc-shaped plates. The upper guiding plate, the lower guiding plate and the two arc-shaped plates are connected to form a waist-shaped plate, and a part of the disengaging section and the reset section are provided on the arc-shaped plates.

[0010] In the above-mentioned intubation device, the first guide member and the second guide member are guide grooves, and the push rod assembly and the straw conveying block are respectively provided with rollers that are slidably matched with the guide grooves.

[0011] In the above-mentioned intubation device, the push rod assembly includes a second slider slidably matched with the sliding rod and a push rod installed on the second slider. The push rod is inserted into the accommodating groove, and an outlet nozzle that matches the shape of the insertion gap is formed at one end of the accommodating groove facing the packaging box.

[0012] In the above-mentioned intubation device, the straw conveying block further includes a side baffle and a scraping plate for scraping the straws into the accommodating groove. The scraping plate and the side baffle are provided at the tops of the opposite side walls of the accommodating groove. The side of the side baffle facing the scraping plate is an inclined surface, and the inclined surface gradually moves away from the scraping plate upward.

[0013] In the above-mentioned intubation device, the straw conveying block further includes a top plate for covering a part of the top of the accommodating groove. The top plate is located between the scraping plate and the outlet nozzle, and the top plate is an inclined plate that is inclined upward in the direction close to the scraping plate.

[0014] In the above-mentioned intubation device, the docking section and the detachment section are transitionally connected through an arc section.

[0015] Advantages of the present invention:

[0016] When the intubation device in the present invention is working, with the transportation of the packaging box, the first guiding member first guides the straw conveying block to slide relative to the sliding rod along the transportation direction, so that the straw conveying block gradually approaches the cup body of the beverage. When the straw conveying block cooperates with the docking section, the straw conveying block abuts against the beverage cup body or inserts into the gap (this gap refers to the space in the packaging box for accommodating the straw). The insertion section will guide the push rod assembly to slide relative to the sliding rod along the transportation direction so that the push rod assembly gradually approaches the straw conveying block. When the push rod assembly cooperates with the other end of the insertion section, the push rod assembly inserts the straw in the accommodating groove into the gap of the packaging box. Since the straw conveying block abuts against the beverage cup body or the straw conveying block inserts into the gap, one end of the continuous straw extending out of the accommodating groove will immediately insert into the gap between the two rows of beverages. The two rows of beverages will restrain one end of the continuous straw, while the accommodating groove will restrain the other end of the continuous straw, which ensures that the continuous straw is always in a controlled state, that is, it ensures that the continuous straw can be inserted into the gap in a tightly arranged stacked state, avoiding the situation of scattering, thereby effectively avoiding the phenomenon of missed insertion of the straw and ensuring the packaging qualification rate; in addition, after the intubation is completed, the disengaging section will guide the straw conveying block to slide relative to the sliding rod so that the straw conveying block gradually moves away from the packaging box to avoid interfering with the transportation of the packaging box and at the same time prepare for the next intubation work; finally, compared with the prior art where the straw conveying block and the push rod assembly are respectively arranged on two pairs of conveyor belts, the present invention only requires two conveyor belts, thereby reducing the manufacturing cost of the intubation device.

[0017] The guiding assembly further includes an upper guiding plate and a lower guiding plate fixed on the frame. The docking section and the insertion section are arranged on the upper guiding plate, a part of the disengaging section is arranged on the lower guiding plate, and the docking section and the disengaging section are connected end to end. The second guiding member further includes a reset section for resetting the push rod assembly, a part of the reset section is arranged on the lower guiding plate, and the reset section and the insertion section are connected end to end. With such a design, the straw conveying block and the push rod assembly can be automatically reset under the drive of the conveyor belt and in cooperation with the guidance of the lower guiding plate, and can maintain the stability of the reset position, so as to facilitate the smooth cooperation of the straw conveying block with the docking section next time and the smooth cooperation of the push rod assembly with the insertion section next time.

[0018] The guiding assembly further includes a first guiding wheel and a second guiding wheel. A first guiding wheel is respectively arranged between the two ends of the upper guiding plate and the lower guiding plate, a part of the disengaging section is arranged on the periphery of the first guiding wheel, a second guiding wheel is respectively arranged between the two ends of the upper guiding plate and the lower guiding plate, and a part of the reset section is arranged on the periphery of the second guiding wheel. With such a design, the first guiding wheel can guide the straw conveying block during the up and down flipping, so as to facilitate the smooth cooperation of the straw conveying block with the lower guiding plate and the upper guiding plate, and the second guiding wheel can guide the push rod assembly during the up and down flipping, so as to facilitate the smooth cooperation of the push rod assembly with the lower guiding plate and the upper guiding plate.

[0019] The intubation device further includes a motor, a first rotating shaft and a second rotating shaft rotatably mounted at both ends of the frame, two driving wheels fixed on the first rotating shaft, and two driven wheels fixed on the second rotating shaft. One conveyor belt is sleeved on one of the driving wheels and one of the driven wheels, and the other conveyor belt is sleeved on the other driving wheel and the other driven wheel. The first rotating shaft is connected to the motor. One of the first guide wheels and the second guide wheels is fixed on the first rotating shaft, and the other first guide wheel and the second guide wheel are fixed on the second rotating shaft. With such a design, by using the first rotating shaft and the second rotating shaft as the installation carriers of the first guide wheel and the second guide wheel, it is possible to save the separate design of other structures for installing the first guide wheel and the second guide wheel, resulting in a simple structure and convenient assembly.

[0020] The first guiding member and the second guiding member are guiding grooves, and the push rod assembly and the straw conveying block are respectively provided with rollers slidably engaged with the guiding grooves. With such a design, it can not only make the movement of the straw conveying block relative to the first guiding member and the movement of the push rod assembly relative to the second guiding member smoother, avoiding jamming, but also save the material cost.

[0021] The push rod assembly includes a second slider slidably engaged with the sliding rod and a push rod mounted on the second slider. The push rod is inserted into the receiving groove, and an outlet pipe opening matching the shape of the insertion gap is formed at one end of the receiving groove facing the packaging box. With such a design, the row of straws can be inserted into the gap in a stacked state matching the shape of the gap, thereby further facilitating the smooth insertion of the straws.

[0022] The straw conveying block further includes side baffles and a scraper for scraping the straws into the receiving groove. The scraper and the side baffles are provided at the tops of the opposite side walls of the receiving groove. One side of the side baffle facing the scraper is an inclined surface that gradually moves away from the scraper upward. With such a design, the row of straws scraped off can be introduced into the receiving groove through the blocking and guiding of the inclined surface, preventing the straws from falling outside the receiving groove.

[0023] The straw conveying block further includes a top plate for covering part of the top of the receiving groove. The top plate is located between the scraper and the outlet pipe opening, and the top plate is an inclined plate inclined upward in the direction close to the scraper. With such a design, it can prevent the row of straws from unfolding and protruding upward from the receiving groove.

[0024] The docking section and the detachment section are connected by an arc section for transition. With such a design, it can ensure that the straw conveying block smoothly switches between the docking section and the detachment section, avoiding jamming.

[0035] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings of the embodiments of the present invention. However, the following embodiments are only the preferred embodiments of the present invention and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present invention.

[0036] Refer to Figures 1 to 6As shown in the figure, the intubation device in this preferred embodiment includes a frame 1, a conveyor belt 2, a bracket 3, a push rod assembly 4, a straw conveying block 5, a motor 6, a first rotating shaft 7, a second rotating shaft 8, a driving wheel 9 and a driven wheel 10. The first rotating shaft 7 and the second rotating shaft 8 are respectively rotatably installed on the frame 1 and are arranged at intervals along the conveying direction of the packaging box. Two driving wheels 9 are respectively installed at both ends of the first rotating shaft 7 and rotate synchronously with the first rotating shaft 7. The first rotating shaft 7 is connected to the motor 6. Two driven wheels 10 are respectively installed at both ends of the second rotating shaft 8 and rotate synchronously with the second rotating shaft 8. The number of conveyor belts 2 is two. One conveyor belt 2 is sleeved on one of the driving wheels 9 and one of the driven wheels 10, and the other conveyor belt 2 is sleeved on the other driving wheel 9 and the other driven wheel 10, thereby realizing the synchronous movement of the two conveyor belts 2.

[0037] The bracket 3 includes a sliding rod 31 extending perpendicular to the conveying direction. Both ends of the sliding rod 31 are respectively fixedly installed on the two conveyor belts 2 so that the conveyor belts 2 drive the bracket 3 to move synchronously. The straw conveying block 5 and the push rod assembly 4 are respectively slidably installed on the sliding rod 31. That is, a first slider 51 is fixedly installed at the bottom of the straw conveying block 5. The first slider 51 is provided with a first through hole for the sliding rod 31 to pass through. The first through hole is slidably matched with the sliding rod 31 so that the straw conveying block 5 reciprocates along the length direction of the sliding rod 31. In addition, the straw conveying block 5 is also provided with a receiving groove 50 with an open upper end for holding straws. The push rod assembly 4 includes a second slider 41 and a push rod 42 fixedly installed on the second slider 41. The second slider 41 is provided with a second through hole for the sliding rod 31 to pass through. The second through hole is slidably matched with the sliding rod 31 so that the push rod assembly 4 reciprocates along the length direction of the sliding rod 31. The push rod 42 extends perpendicular to the conveying direction. One end of the push rod 42 is inserted into the receiving groove 50, and an outlet port 501 is provided at one end of the receiving groove 50 close to the packaging box.

[0038] In addition, a guiding assembly located between two conveyor belts 2 is further provided on the rack 1 in this preferred embodiment. The guiding assembly includes an upper guiding plate 11, a lower guiding plate 12, a first guiding member 13 and a second guiding member 14. The upper guiding plate 11 is located above the lower guiding plate 12. The first guiding member 13 is slidably engaged with the first slider 51, and the second guiding member 14 is slidably engaged with the second slider 41. Preferably, in order to reduce the material cost, both the first guiding member 13 and the second guiding member 14 are guiding grooves provided on the upper guiding plate 11 and the lower guiding plate 12. A roller slidably engaged with the first guiding member 13 is provided at the bottom of the first slider 51, and a roller slidably engaged with the second guiding member 14 is provided at the bottom of the second slider 41. The first guiding member 13 includes a butt joint section 130 and a disengaging section 131 connected end to end. The butt joint section 130 is provided on the upper guiding plate 11, and the disengaging section 131 is partially provided on the lower guiding plate 12 and partially provided on the upper guiding plate 11. The butt joint section 130 and the disengaging section 131 are respectively parallel to the conveyor belt 2. The butt joint section 130 is closer to the packaging box than the disengaging section 131, and the two ends of the butt joint section 130 and the disengaging section 131 are connected by an arc section for smooth transition, so as to ensure that the first slider 51 can smoothly switch between the butt joint section 130 and the disengaging section 131 and avoid jamming. When the first slider 51 is engaged with the butt joint section 130, the straw conveying block 5 abuts against the beverage cup body, and when the first slider 51 is engaged with the disengaging section 131, the straw conveying block 5 moves away from the packaging box to avoid interfering with the conveyance of the packaging box.

[0039] The second guide member 14 includes an insertion section 141 and a reset section 142. The insertion section 141 is arranged on the upper guide plate 11 and is arc-shaped. The insertion section 141 is arranged corresponding to the docking section 130. One end of the insertion section 141 is far from the docking section 130, and the other end extends along the conveying direction and gradually approaches the docking section 130. The reset section 142 includes a transition section 1421, an inclined section 1422, and a straight section 1423 that are connected in sequence. Both the straight section 1423 and the transition section 1421 are parallel to the conveyor belt 2. The transition section 1421 is arranged on the upper guide plate 11 and is connected to the end of the insertion section 141 close to the docking section 130 through an arc section. Both the transition section 1421 and the inclined section 1422 are arranged corresponding to the separation section 131. The inclined section 1422 is arranged on the lower guide plate 12 and is connected to the transition section 1421. A part of the straight section 1423 is arranged on the lower guide plate 12 to be connected to the inclined section 1422, and the other part is arranged on the upper guide plate 11 and is connected to the end of the insertion section 141 far from the docking section 130. The end of the straight section 1423 arranged on the upper guide plate 11 and connected to the insertion section 141 is arranged corresponding to the docking section 130. When the second slider 41 cooperates with the insertion section 141, the push rod 42 gradually pushes out the straw in the receiving groove 50. When the second slider 41 cooperates with the other end of the insertion section 141, the straw in the receiving groove is pushed into the gap. When the second slider 41 cooperates with the transition section 1421 and the inclined section 1422, the push rod assembly 4 gradually moves away from the straw conveying block 5. When the second slider 41 cooperates with the straight section 1423, the second slider 41 resets to the initial state and maintains the stability of its reset position, so that the receiving groove 50 can hold the next row of connected straws. That is, by using the guide assembly in this embodiment, the straw conveying block 5 and the push rod assembly 4 can be automatically reset under the drive of the conveyor belt 2 and the guidance of the lower guide plate 12, and can maintain the stability of the reset position, so as to facilitate the smooth cooperation between the straw conveying block 5 and the docking section 130 next time and the smooth cooperation between the push rod assembly 4 and the insertion section 141 next time.

[0040] Secondly, the guiding assembly in this preferred embodiment further includes a first guiding wheel 15 and a second guiding wheel 16. One first guiding wheel 15 and one second guiding wheel 16 are mounted on the first rotating shaft 7. The first guiding wheel 15 and the second guiding wheel 16 are located between two driving wheels 9. One first guiding wheel 15 and one second guiding wheel 16 are mounted on the second rotating shaft 8. The first guiding wheel 15 and the second guiding wheel 16 are located between two driven wheels 10. A partial disengaging section 131 is provided on the circumferential side of the first guiding wheel 15. The reset section 142 further includes a guiding section 1424 provided on the circumferential side of the second guiding wheel 16. The guiding section 1424 connects the transition section 1421 and the inclined line section 1422. With such a design, it is possible to guide the straw conveying block 5 during up-and-down flipping through the first guiding wheel 15, so as to facilitate the smooth cooperation between the first slider 51 and the disengaging section 131 on the lower guiding plate 12 and the upper guiding plate 11, and it is possible to guide the push rod assembly 4 during up-and-down flipping through the second guiding wheel 16, so as to facilitate the smooth cooperation between the second slider 41 and the inclined line section 1422 of the lower guiding plate 12 and the straight line section 1423 of the upper guiding plate 11. In addition, by using the first rotating shaft 7 and the second rotating shaft 8 as the installation carriers for the first guiding wheel 15 and the second guiding wheel 16, it is possible to save the design of other structures for installing the first guiding wheel 15 and the second guiding wheel 16 separately. Thus, the structure is simple and the assembly is convenient.

[0041] Finally, the straw conveying block 5 in this preferred embodiment further includes side baffles 52 and a scraper 53 for scraping the straws into the receiving groove 50. A plurality of scrapers 53 are arranged at intervals along the moving direction of the push rod 42. The scraper 53 and the side baffles 52 are provided at the tops of the opposite side walls of the receiving groove 50. The side of the side baffle 52 facing the scraper 53 is an inclined surface 521, and the inclined surface 521 gradually moves away from the scraper 53 upwards. With such a design, the row of scraped straws can be introduced into the receiving groove 50 through the blocking and guiding of the inclined surface 521, avoiding the straws from falling outside the receiving groove 50.

[0042] When the intubation device in the present invention is working, with the transportation of the packaging box, when the straw conveying block 5 is above the upper guide plate 11, it first cooperates with the disengagement section 131, and then cooperates with the docking section 130 under the drive of the conveyor belt 2. At this time, the straw conveying block 5 abuts against the beverage cup body, and the straw conveying block 5 and the packaging box move synchronously along the conveying direction. During the movement in the conveying direction, the scraper 53 on the straw conveying block 5 will scrape the straws on the continuous straw supply device 01 into the receiving groove 50. Before the straws fall into the receiving groove 50, the second slider 41 on the push rod assembly 4 cooperates with the straight section 1423 to prevent interference and cause the straws to fail to fall into the receiving groove 50. After the straws fall into the receiving groove 50, the second slider 41 cooperates with the insertion section 141 and moves in the direction close to the straw conveying block 5 under the guidance of the insertion section 141, so that the push rod 42 gradually pushes out the straws in the receiving groove 50. When the second slider 41 cooperates with the end of the insertion section 141 close to the docking section 130, the straws in the receiving groove 50 are pushed into the gap, thus completing the packaging of the continuous straws. Subsequently, the straw conveying block 5 cooperates with the disengagement section 131 to move away from the packaging box and reset, so as to avoid interfering with the transportation of the packaging box and also prepare for the next intubation. At the same time, the second slider 41 cooperates with the reset section 142 and resets to prepare for the next tube pushing action.

[0043] Since in the intubation device in this preferred embodiment, the straw conveying block 5 abuts against the beverage cup body during the intubation action, after the push rod 42 pushes the continuous straws out of the receiving groove 50, one end of the continuous straws extending out of the receiving groove 50 will immediately be inserted into the gap between two rows of beverages. The two rows of beverages will restrain one end of the continuous straws, and the receiving groove 50 will restrain the other end of the continuous straws, which ensures that the continuous straws are always in a controlled state, that is, it ensures that the continuous straws can be inserted into the gap in a closely arranged stacked state, avoiding the situation of spreading, thereby effectively avoiding the phenomenon of missed insertion of straws and ensuring the packaging qualification rate; finally, compared with the prior art where the straw conveying block and the push rod assembly are respectively arranged on two pairs of conveyor belts, only two conveyor belts are required in this embodiment, thereby reducing the manufacturing cost of the intubation device.

[0044] Preferably, the straw conveying block 5 in this preferred embodiment further includes a top plate 54 for shielding a part of the top of the receiving groove 50. The top plate 54 is located between the scraper 53 and the outlet 501, and the top plate 54 is an inclined plate inclined upward in the direction close to the scraper 53. Designed in this way, it can prevent the continuous straws from slipping out of the receiving groove 50 upward after unfolding.

[0045] Preferably, the shape of the outlet 501 in this preferred embodiment matches the shape of the gap between the two rows of beverage cup bodies. Designed in this way, it can enable the continuous straws to be inserted into the gap in a stacked state with the same shape as the gap, thereby further facilitating the smooth insertion of the straws.

[0046] It is understandable that in other embodiments of the present invention, when the straw conveying block cooperates with the docking section, one end of the straw conveying block can also be inserted into the gap between two rows of beverages. In this way, it can also ensure that the straws are inserted into the gap in a closely arranged stacked state.

[0047] It is understandable that in other embodiments of the present invention, the first guiding member and the second guiding member can also be guiding ribs.

[0048] It is understandable that in other embodiments of the present invention, the guiding assembly further includes two arc-shaped plates. The upper guiding plate, the lower guiding plate and the two arc-shaped plates are connected to form a waist-shaped plate, and a partial disengaging section and a reset section are arranged on the arc-shaped plates.

[0049] As described above, the above are only the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
