Description
Technical Field
The utility model relates to a case sealer's core especially relates to a high-speed case sealer core.
Background
The case sealer is used for packing the product case sealer, so that the product case sealer is convenient to store and transport. The sealing speed of the existing sealing machine is only dozens of boxes/minute generally, and the ideal sealing speed is thirty or more boxes/minute. How to increase the speed of the case sealer is always a problem considered in the industry.
The movement of the carton sealing machine shown in fig. 1 is used for sealing a carton by sticking adhesive tapes. The box sealing states a to d show the box sealing principle of the box sealing machine core.
Referring to fig. 1, which is a top view, as shown in a state diagram, the carton 80 'moves rightwards on the side of the movement, the side edge of the front end of the carton 80' hits the front pressing wheel 23 ', and the adhesive tape 31' staying on the front pressing wheel 23 'is adhered (the adhesive surface of the adhesive tape 31' faces towards the direction of the box). Since the carton 80 ' has a certain traveling speed, the front pinch roller 23 ' and the front swivel arm 21 ' need to be started to swivel as soon as possible.
As shown in the state b, the paper box 80 ' pushes the front pressing wheel 23 ' to rotate together with the front rotating arm 21 '. Because the front rotating arm 21 'and the rear rotating arm 22' are linked by the linkage rod 25 ', and the spring 50' is connected to the rear rotating arm 22 ', the spring 50' is stretched, and the elastic force of the spring 50 'indirectly causes the front pressing wheel 23' to press the side surface of the carton 80 'so that the adhesive tape is adhered to the side surface of the carton 80'.
As shown in the state b, the paper box 80 ' pushes the outer end of the knife arm 41 ' at the same time, and the outer end of the knife arm 41 ' is provided with the blade 42 ' inward a short distance, and the blade 42 ' is spaced a short distance from the paper box 80 ' without cutting the adhesive tape 31 '.
As shown in the state c, the paper box 80 'is separated from the front pressing wheel 23', and then the paper box 80 'is separated from the outer end of the knife arm 41', the knife arm 41 'rotates clockwise due to the action of the spring (the spring is not shown in the figure), the knife 42' rotates clockwise, and the knife 42 'cuts off the adhesive tape 31'. At this point, the rear press wheels 24 'remain pressed against the carton 80'.
As shown in the state diagram d, the carton 80 ' still moves, and the rear pressing wheel 24 ' needs to rotate counterclockwise rapidly to cling the rear section of adhesive tape to the side of the rear end of the carton 80 '.
Thus, the automatic box sealing is completed.
From the above-mentioned carton sealing step, it can be seen that when the carton 80 ' enters, the front pressing wheel 23 ' needs to make a rapid rotational motion under the pushing of the carton 80 ' to match the traveling speed of the carton 80 ', and the stiffness coefficient of the spring 50 ' is required to be as low as possible. When the carton 80 ' is going to leave, the pressing force of the rear pressing wheel 24 ' by the carton 80 ' is being released, and the rear pressing wheel 24 ' needs to rapidly rotate, so that the linear velocity generated by the rotation in the traveling direction of the carton 80 ' exceeds the carton 80 ', so that the rear pressing wheel 24 ' can be pressed against the rear wall of the carton 80 ' to adhere to the adhesive tape, and the stiffness coefficient of the spring 50 ' is required to be as high as possible. Thus, there is a contradiction to the stiffness coefficient requirement of the spring 50'. Therefore, the advancing speed of the paper box 80 'is limited, and poor adhesion is easily caused after the advancing speed of the paper box 80' is improved, so that the box sealing efficiency is not high. Even when the speed of the carton 80 'is too high, the carton 80' hits the front press wheels 23 ', which easily causes the carton 80' to deform.
In order to solve the above contradiction, chinese patent document "CN 108528845 a" discloses a case sealer core with the structure of fig. 2, which is additionally provided with an air cylinder 51 ', the air cylinder 51 ' is connected with the spring 50 ' in series, and the air cylinder is deflated at the beginning of case sealing to relax the spring; when the sealing box is close to the end, the cylinder is inflated to tension the spring and increase the elasticity of the spring. Therefore, the contradiction between the reaction speed of the front pinch roller at the beginning of the box sealing and the reaction speed of the rear pinch roller at the end of the box sealing is solved.
The utility model aims at providing another kind of scheme and solve the initial time preceding pinch roller reaction rate of joint sealing and close on the contradiction between the back pinch roller reaction rate when the joint sealing finishes.

Example 1
As shown in fig. 3, the high-speed case sealer core includes a fixing plate 10, the fixing plate 10 is provided with an upper block and a lower block, and the upper block is removed to show the internal structure of the core, and only the lower block is shown.
The fixing plate 10 mainly serves as a support for mounting other components.
The high-speed carton sealing machine movement further comprises a pressing wheel assembly 20, an adhesive tape mounting assembly 30, a tape cutting assembly 40 and an elastic assembly 50 which are mounted on the fixing plate 10.
The pressing wheel assembly 20 comprises a front rotating arm 21 rotatably arranged on the fixing plate 10, a rear rotating arm 22 rotatably arranged on the fixing plate 10, a front pressing wheel 23 arranged at the outer end of the front rotating arm 21, a rear pressing wheel 24 arranged at the outer end of the rear rotating arm 22 and a linkage rod 25. Two ends of the linkage rod 25 are respectively hinged with the front rotating arm 21 and the rear rotating arm 22, so that one of the front rotating arm 21 and the rear rotating arm 22 can rotate to drive the other to rotate, namely the linkage rod 25 plays a linkage role.
An adhesive tape mounting assembly 30 is arranged near the front rotating arm 21, and the adhesive tape mounting assembly 30 extends the adhesive tape to the front pressure wheel 23 in a zigzag manner. As shown in fig. 3, the end of the adhesive tape is approximately left at the front pressing wheel 23, the adhesive surface faces left, and the paper box to be sealed enters the box sealing machine core from left to right.
As the carton enters from left to right in fig. 3, the carton pushes the outer end a, causing the knife arm 41 to rotate counterclockwise by a small angle. A blade 42 is provided a small distance inwards at the outer end a. When the carton is tightly propped against the outer end a, the blade 42 is not contacted with the adhesive tape; as the carton continues to travel to the right to disengage the outer end a of the knife arm 41 (i.e., disengage the knife arm 41), the knife arm 41 rotates back clockwise such that the blade 42 contacts and severs the tape.
The resilient member 50 includes a fixed end 51 and a movable end 52. Wherein the fixed end 51 is fixed on the fixed plate 10. The moving end 52 is connected to the rear rotating arm 22, and the moving end 52 moves in accordance with the rotation of the rear rotating arm 22.
As shown in fig. 3 and 4, the spring assembly 50 includes a first spring 53, a second spring 54, an intermediate coupling member 55, and a stopper 56. The stiffness coefficient of the first spring 53 is larger than that of the second spring 54. The intermediate link 55 is disposed between the first spring 53 and the second spring 54, and the stopper 56 is disposed on a moving path of the intermediate link 55.
Referring to fig. 4, the stopping member 56 is provided with a fixing post, i.e. a position where the fixing end 51 of the elastic member 50 is located. The fixed end 51 is rotatably fixed to the stationary plate 10. The stopper 56 has a stopper wall 562 for stopping, and a lumen 561 is provided on one side (i.e., the left side) of the stopper wall 562. The intermediate connector 55 is disposed in the lumen 561 and can move more firmly within the lumen 561. A second spring 54 is also disposed in the lumen 561.
When the moving end 52 is pulled, the second spring 54 is compressed by the head 552 on the left side, and the first spring 53 is extended. And since the stiffness coefficient of the first spring 53 is larger than that of the second spring 54, the second spring 54 is mainly deformed. When the second spring 54 is compressed to the limit, the intermediate connecting member 55 together with the second spring 54 is stopped by the blocking wall 562 of the blocking member 56, i.e. the maximum amplitude of the movement of the intermediate connecting member 55 in one direction is limited by said blocking wall 562. At this time, mainly the first spring 53 is deformed. It is believed that the combined stiffness of the resilient member 50 is lower during the initial stage of pulling the movable end 52 and higher during the final stage of pulling the movable end 52. Since the carton enters the carton sealing machine core at a high speed in the initial stage of pulling the movable end 52, the front pressing wheel 23 needs to perform a rapid rotating action to match the speed of the carton, and the comprehensive stiffness coefficient of the elastic component 50 is preferably small. When the carton releases the rear pressing wheel 24, the rear pressing wheel 24 needs to quickly make a circling motion to catch up with the high-speed advancing speed of the carton and cling to the rear side face of the carton, so that the adhesive tape clings to the rear side edge of the carton. It is desirable that the overall stiffness of the resilient member 50 be relatively high.
Therefore, the carton sealing speed of the carton can be greatly improved, and the practice can reach at least more than 70 cartons per minute.
In this embodiment, the stop member 56 is rotatably disposed on the fixed plate 10 to match the rotation of the movable end 52 when moving relative to the fixed end 51. In other technical solutions, the stopping member 56 may not be rotatably disposed, and it is also possible to realize that the intermediate connecting member 55 is stopped by the stopping member 56 when moving to a certain position.
As shown in fig. 3, the resilient member 50 further includes a third spring 57. A third spring 57 is connected between the linkage rod 25 and the rear rotating arm 22. When the rear rotating arm 22 rotates, the third spring 57 is stretched to some extent. The third spring 57 assists in providing a return force for the swivel of the rear rotating arm 22. The elasticity of the whole elastic component 50 is changed more softly, and the vibration of the movement of the carton sealing machine is reduced.
As shown in fig. 3, the linkage rod 25 is provided with a plurality of connection holes 251, the connection holes 251 are used for connecting one end of the third spring 57, and the connection holes 251 are selectively connected in one of the connection holes 251, so as to adjust the tension of the third spring 57.
Example 2
As shown in fig. 5, the embodiment 2 is different from the embodiment 1 in the structure of the elastic member 50.
In the embodiment 2, as shown in fig. 5, the fixed end 51 and the movable end 52 of the elastic member 50 are respectively connected to one ends of two first springs 53, the other ends of the two first springs 53 are respectively connected to an intermediate connecting member 55, and a second spring 54 is fixedly connected between the two intermediate connecting members. The two intermediate links 55 and the second spring 54 are provided with stoppers 56 around their outer peripheries. The stop 56 also has a lumen 561 and a stop wall 562.
In this structure, the distance between the fixed end 51 and the movable end 52 can be made longer, and the structure is suitable for sealing large cartons.
The utility model discloses a case sealer core can make the joint sealing speed reach sixty case/minute, and the linear velocity reaches 50 meters/minute at least, and current linear velocity mostly only is 10 meters/minute, if can reach 30 meters/minute just high-speed joint sealing, the utility model discloses can greatly improve the joint sealing speed.
The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention, so as not to limit the protection scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
