Description

Technical Field

[0001] The utility model relates to the field of carton production, in particular to an adhesive device for carton production. Background Technique

[0002] In the existing carton gluing method, such as the solution with the authorization announcement number CN213972817U, when in use, the roller conveyor 7 works to convey the cartons. Then, the switch valve on the glue output pipe 8 is opened, and the glue is conveyed through the glue output pipe 8. The glue will drip and smear on the top of the carton. The L-shaped scraper 11 can evenly smear the glue on the carton, and the L-shaped scraper 11 can push the excess glue from the inlet 10 into the recovery box 9. Although the glue can be leveled and the excess glue can be scraped off in this way, there are still the following problems;

[0003] 1. When the glue drips and is scraped off, in order to ensure that the cartons can be conveyed on the roller conveyor 7, there must be intervals between the cartons and the front and rear sides to prevent the cartons from colliding. Due to the interval between the carton and the inlet 10, the excess glue will also flow downward, resulting in the sides of the carton being coated with glue, and at the same time, it is difficult to achieve the effect of collecting the glue.

[0004] 2. When continuously gluing, that is, when one carton after another is placed on the roller conveyor 7 for conveyance, in order to prevent dripping on the lower side, it is necessary to manually control the opening and closing of the switch back and forth, which is cumbersome to operate. Summary of the Invention

[0005] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an adhesive device for carton production, which effectively solves the problems of glue flowing downward and dripping.

[0006] The technical solution it adopts is that an adhesive device for carton production includes two horizontal bars placed left and right in the front and back. A plurality of roller conveyors are evenly distributed left and right between the two horizontal bars, and the axes of the roller conveyors are arranged front and back. A vertical plate is fixed on each of the front and back sides of the two horizontal bars, and the upper side of the vertical plate is higher than the horizontal bar. A hollow housing is fixed between the two vertical plates. A telescopic rod is fixed on each of the front and back sides of the lower end surface of the housing. A rotatable round rod is installed on the lower side of the telescopic rod, and the axis of the round rod is arranged front and back. A brush evenly distributed in the circumferential direction is fixed on the outer edge of the round rod. The telescopic rod is composed of two hollow rods, and the inner side of the rod on the upper side is communicated with the inside of the housing; the outer end of the brush on the round rod can block the lower end of the telescopic rod, and the telescopic rod is always subjected to an upward moving force; the brush is located between the two roller conveyors;

[0007] When the telescopic rod moves upward, the lower side of the brush is located above the roller conveyor, and the upper and lower parts inside the telescopic rod are not connected; when the telescopic rod moves downward, the lower side of the brush is located below the upper side of the roller conveyor and the round rod is located above the roller conveyor, and the upper and lower parts inside the telescopic rod are connected.

[0008] The inner rod of the telescopic rod is located on the upper side and is connected to the inside of the housing. A spring is sleeved on the inner rod of the telescopic rod. One end of the spring is fixed on the housing, and the other end of the spring is fixed on the outer rod of the telescopic rod. The spring gives an upward force to the outer rod of the telescopic rod.

[0009] On both sides of the lower end of the housing, two vertical rods placed up and down are fixed respectively. The two vertical rods on the corresponding side are arranged front and back. A swing rod arranged left and right is hinged on each vertical rod, and the hinged position is located in the middle of the swing rod. The left and right ends of the swing rod can swing up and down. A long circular hole along the length direction is opened on the front side of one end of the swing rod. A short rod arranged front and back is fixed inside the outer rod of the telescopic rod. The swing rod is sleeved on the short rod through the long circular hole, and the swing of the swing rod can drive the outer rod of the telescopic rod to move downward;

[0010] On the other end of the two swing rods on the corresponding side, a pressing wheel is rotated. The axis of the pressing wheel is arranged front and back, and is located between the front and back directions of the front and back brushes. When the telescopic rod moves upward, the lower side of the pressing wheel is located below the upper side of the roller conveyor. When the telescopic rod moves downward, the pressing wheel is located on the upper side of the roller conveyor, and the axis of the pressing wheel is always higher than the upper side of the roller conveyor.

[0011] A cover body with an open lower end is fixed at the lower end of the telescopic rod. The round rod rotates on the cover body. The lower side of the brush is located below the open lower end of the cover body. The inner end of the round rod penetrates through the cover body and extends out of the cover body. A first friction wheel is fixed at the extending end of the round rod. A second friction wheel is rotated on one side of the cover body where the first friction wheel is located. The rotation of the second friction wheel can drive the first friction wheel to rotate, and the lower side of the second friction wheel is located below the cover body.

[0012] A ring smaller than the inner diameter of the outer rod and larger than the inner diameter of the inner rod is fixed inside the outer rod of the telescopic rod, and the ring is coaxial with the telescopic rod.

[0013] In the utility model, since the two telescopic rods are of a hollow structure and the brush can block the open lower end of the telescopic rod, it can not only make the glue flow downward but also prevent the problem that too much glue flows out after soaking into the brush;

[0014] Moreover, the upper part of the telescopic rod can be completely separated up and down by the ring, and the problem that the glue moves into the brush and drips during non-use can be avoided. Brief Description of the Drawings

[0020] The following further elaborates in detail on the specific embodiments of the present utility model in conjunction with the accompanying drawings.

[0021] It is given by Figures 1 to 5 The present utility model includes two cross bars 1 placed horizontally from front to back. Between the two cross bars 1, a plurality of drum conveyors 2 are evenly distributed left and right. The axes of the drum conveyors 2 are arranged from front to back. On the front and back sides of the two cross bars 1, a vertical plate 3 is fixed respectively. The upper side of the vertical plate 3 is higher than the cross bar 1. A hollow housing 4 is fixed between the two vertical plates 3. On the front and back sides of the lower end surface of the housing 4, a telescopic rod 5 is fixed respectively. A rotatable round rod 6 is installed on the lower side of the telescopic rod 5. The axis of the round rod 6 is arranged from front to back. A brush 7 evenly distributed in the circumferential direction is fixed on the outer edge of the round rod 6. The telescopic rod 5 is composed of two hollow rods. The inner side of the rod on the upper side is communicated with the inside of the housing 4. The outer end of the brush 7 on the round rod 6 can block the lower end of the telescopic rod 5. The telescopic rod 5 is always subjected to an upward force. The brush 7 is located between the two drum conveyors 2;

[0022] When the telescopic rod 5 moves upward, the lower side of the brush 7 is located above the drum conveyor 2, and the upper and lower sides of the inner side of the telescopic rod 5 are not communicated; when the telescopic rod 5 moves downward, the lower side of the brush 7 is located below the upper side of the drum conveyor 2 and the round rod 6 is located above the drum conveyor 2, and the upper and lower sides of the inner side of the telescopic rod 5 are communicated.

[0023] The inner rod of the telescopic rod 5 is located on the upper side and is communicated with the inside of the housing 4. A spring is sleeved on the inner rod of the telescopic rod 5. One end of the spring is fixed on the housing 4, and the other end of the spring is fixed on the outer rod of the telescopic rod 5. The spring gives an upward force to the outer rod of the telescopic rod 5.

[0024] On both sides of the lower end of the described housing 4, two vertical rods 8 placed one above the other are fixed respectively. The two vertical rods 8 on the corresponding side are arranged front and back. A swing rod 9 arranged left and right is hinged on each vertical rod 8. The hinged position is located in the middle of the swing rod 9. The left and right ends of the swing rod 9 can swing up and down. A long circular hole along the length direction is formed on the front side of one end of the swing rod 9. A short rod 10 arranged front and back is fixed inside the outer rod of the telescopic rod 5. The swing rod 9 is sleeved on the short rod 10 through the long circular hole. The swinging of the swing rod 9 can drive the outer rod of the telescopic rod 5 to move downward.

[0025] A pressing wheel 11 is rotated at the other end of the two swing rods 9 on the corresponding side. The axis of the pressing wheel 11 is arranged front and back, and is located between the front and back directions of the front and back brush hairs 7. And when the telescopic rod 5 moves upward, the lower side of the pressing wheel 11 is located at the lower side above the roller conveyor 2. After the telescopic rod 5 moves downward, the pressing wheel 11 is located on the upper side of the roller conveyor 2, and the axis of the pressing wheel 11 is always higher than the upper side of the roller conveyor 2.

[0026] A housing 12 with an open lower end is fixed at the lower end of the described telescopic rod 5. The round rod 6 rotates on the housing 12. The lower side of the brush hair 7 is located at the lower side of the open lower end of the housing 12. The inner end of the round rod 6 penetrates through the housing 12 and extends out of the housing 12. A first friction wheel 13 is fixed at the extending end of the round rod 6. A second friction wheel 14 is rotated on one side of the housing 12 where the first friction wheel 13 is located. The rotation of the second friction wheel 14 can drive the first friction wheel 13 to rotate. The lower side of the second friction wheel 14 is located at the lower side of the housing 12.

[0027] When the second friction wheel 14 rotates, it can drive the first friction wheel 13 to rotate in the opposite direction and further drive the brush hair 7 to rotate in the opposite direction.

[0028] A ring 15 smaller than the inner diameter of the outer rod and larger than the inner diameter of the inner rod is fixed inside the outer rod of the described telescopic rod 5. The ring 15 is coaxial with the telescopic rod 5.

[0029] When the outer rod of the telescopic rod 5 moves upward, the round rod 6 can block the lower end of the inner rod of the telescopic rod 5; when the outer rod of the telescopic rod 5 moves downward, the lower end of the inner rod of the telescopic rod 5 is not blocked. And because the diameter of the ring 15 is smaller than the inner diameter of the outer rod, the inside of the outer rod of the telescopic rod 5 is vertically communicated.

[0030] It is worth mentioning that a stirring rod 16 and a heating sheet 17 are provided inside the housing 4. The stirring rod 16 is driven by a motor 18.

[0031] Before the utility model is used, the telescopic rod 5 moves to the uppermost side of the displacement under the action of the spring, and the ring 15 blocks the lower end of the inner rod of the telescopic rod 5;

[0032] When the utility model is in use, glue is placed in the housing 4, the motor 18 is started and heated to make the glue fluid, and the heat is evenly distributed through the stirring rod 16. First, the cardboard can be placed on the top of the roller conveyor 2, and the roller conveyor 2 works to convey the cardboard. When the cardboard passes through the pressing wheel 11, the cardboard will push the pressing wheel 11, and the pressing wheel 11 will move upward to the upper side of the cardboard. The upward movement of the pressing wheel 11 drives the outer rod of the telescopic rod 5 to move downward through the hinge. At the same time, the telescopic rod 5 is connected up and down, and the glue in the housing 4 will flow to the upper side of the brush 7 through the telescopic rod 5 and soak into the brush 7. Since the glue is hot melt glue and its fluidity is not high, the brush 7 can prevent the glue from dripping;

[0033] Since the telescopic rod 5 moves downward, it will drive the brush 7 to move downward. When the cardboard moves to the position of the brush 7, the brush 7 can contact the upper side of the cardboard. At the same time, the second friction wheel 14 on the cover 12 will contact the upper end face of the cardboard and rotate with the movement of the cardboard. The rotation of the second friction wheel 14 drives the brush 7 to rotate through the first friction wheel 13. The brush 7 can rotate to brush the soaked glue at the position where the cardboard needs to be glued, and there will be no problems of excessive glue dripping and unevenness;

[0034] The cardboard continues to be conveyed. Since there is a pressing wheel 11 on each of the left and right sides of the brush 7, as long as one of the two pressing wheels 11 falls on the upper side of the cardboard, the telescopic rod 5 is located on the lower side of the displacement, and the brush 7 can continue to brush the glue, and the gluing can be completed without missing brushing;

[0035] When the cardboard is separated from both pressing wheels 11, the spring pulls the outer rod of the telescopic rod 5 to move upward, and the upper and lower parts of the telescopic rod 5 are separated by the ring 15 again, and the glue stops flowing downward.

[0036] 1. The utility model has the hollow structure of the two telescopic rods 5, and the brush 7 can block the lower opening of the telescopic rod 5, which can not only make the glue flow downward, but also prevent the glue from flowing out too much after soaking into the brush 7;

[0037] And the upper part of the telescopic rod 5 can be completely separated up and down by the ring 15, which can prevent the glue from moving into the brush 7 and dripping during non-use.

[0038] 2. The utility model smears the glue on the cardboard by rotating the brush 7, which not only plays the role of gluing, but also can evenly sweep the glue to prevent the problem of uneven glue smearing, and there is no need to scrape off the excess glue.

[0039] 3. With the pressing wheels 11 on both the left and right sides, the telescopic rod 5 can be driven to move downward. Before and after the cardboard box enters the gluing position, the brush 7 moves downward to prepare for gluing, and the telescopic rod 5 can move upward only after the cardboard box exits from the other pressing wheel 11, ensuring that the gluing position of the cardboard box can be glued.

[0040] 4. The utility model does not need to manually control the gluing switch, and can solve the problem of manually controlling the switch back and forth to prevent glue dripping during continuous gluing.
