Description

Technical Field

[0001] The utility model relates to the field of carton processing auxiliary components, in particular to a precise slotting line device for carton processing. Background Art

[0002] Cartons are the most widely used packaging products. Depending on the materials used, there are corrugated boxes, single-layer cardboard boxes, etc., with various specifications and models. Different from wooden box packaging, woven bag packaging, cloth bag packaging and plastic box packaging, carton packaging has the characteristics of easy material acquisition, light weight, easy printing, easy design and molding, and low cost. Therefore, it is widely used in sales packaging and transportation packaging of goods.

[0003] In the process of carton processing, the raw material of carton is cardboard. Before the cardboard is made into carton, precise slotting line processing is an indispensable step in the process of carton processing. Specifically, in the operation, the staff places the cardboard on the conveying mechanism, and then the conveying mechanism conveys the cardboard to the slotting line mechanism position for precise slotting line processing, so that the processed cardboard can be conveniently made into carton in the subsequent process.

[0004] However, in the actual use of the slotting line mechanism, firstly, some waste paper scraps will be cut during the slotting line processing, and these waste paper scraps are usually directly scattered on the base of the slotting line mechanism, which is very inconvenient to collect and clean. At the same time, when the cardboard is transmitted to the base after the slotting line is completed, the cardboard will rely on inertia to scatter directly on the base. When it is necessary to collect and remove these cardboards, workers are often required to collect these cardboards specifically, which is inconvenient for workers to collect and remove these cardboards.

[0017] Preferably, the top end surface of the material collection box is flush with the top end surface of the material drop opening, and the outer rear portion of the material collection box is in close contact with the inner rear portion of the material drop opening.

[0018] The above-mentioned precise slotting line device for carton processing is adopted. Specifically, during the use of the cardboard slotting line, the cardboard is translated and transported to the cardboard slotting line mechanism by the cardboard conveying mechanism and is slotted by the cardboard slotting line mechanism. Since the pad at the front of the base is equipped with the limit stop assembly for preventing the cardboard that is transported and dropped by the cardboard slotting line mechanism from scattering on the top surface of the pad, the setting of the limit stop assembly can block and limit the falling cardboard at the front. Specifically, during operation, the end is held and the clamping stud is reversed counterclockwise to make the elastic pressure block leave the bottom of the adjusting groove, and then the movable seat of the limit stop assembly slides longitudinally along the slide groove and moves clockwise. The elastic pressure block at the bottom end of the pressing stud is tightened by the needle in the forward rotation and pressed on the bottom of the adjusting groove, so that the longitudinal position of the baffle can be adjusted, and then the baffle is adjusted to a suitable position in the longitudinal direction to block and limit the falling cardboard at the front, thereby enriching the general use range of the limit stop component and improving the use flexibility of the limit stop component. The baffle can be adjusted to a suitable position with reference to the position state of the falling cardboard. After the baffle is adjusted into place, the cardboard falling through the cardboard slotting line mechanism can be blocked and limited at the front. At the same time, since the side limit components are extended on both sides of the limit stop component, the falling paper can be blocked by the setting of the side limit components. The plate is used to block and limit the side of the plate. Specifically, during operation, after the limiting nuts on the same side are screwed respectively, the distance between the limiting side plates at both sides can be adjusted by the adjusting studs of the side limiting assembly sliding laterally along the slide groove and by screwing the limiting nuts to press against the surface of the wing plate. This makes it easy to adjust the limiting side plates to a suitable position in the horizontal direction to block and limit the side of the cardboard being conveyed and fallen, thereby enriching the general use scope of the side limiting assembly and improving the use flexibility of the side limiting assembly. The distance between the limiting side plates at both sides can be adjusted appropriately according to the position state of the cardboard falling, and the limiting side plates at both sides can be adjusted to a suitable position. After the limiting side plates are adjusted into position, the cardboards conveyed and dropped by the cardboard slotting line mechanism can be blocked and limited on both sides. In this way, since the cardboards conveyed and dropped by the cardboard slotting line mechanism are blocked and limited from the front and both sides respectively, the cardboards conveyed and dropped by the cardboard slotting line mechanism can be prevented from scattering on the top surface of the pad, so that workers can collect and remove the cardboards. Specifically, as to the blanking opening position of the cardboard slotting line mechanism, since the cardboard slotting line mechanism is provided with the waste collection component for collecting waste paper scraps generated in the slotting and cutting process of the cardboard slotting line mechanism at the position of the blanking opening, the workers can clean the waste paper scraps generated in the slotting and cutting process of the cardboard slotting line mechanism into the collection box.In this way, the waste paper scraps generated during the slotting and cutting process of the cardboard slotting line mechanism can be collected in a centralized manner through the collection box of the waste collection assembly, thereby avoiding the waste paper scraps being scattered on the top surface of the base and being inconvenient to collect and clean. Specifically, when the collection box and the blanking opening are combined, at the beginning, the outer periphery of the collection box and the inner periphery of the blanking opening are vertically slidably matched, and the limit rod and the limit hole are horizontally slidably matched. At this time, the collection box and the blanking opening are vertically slidably matched, and the limit rod and the limit hole are horizontally slidably matched. The lateral sliding fit method can detachably fix the collection box to the inner periphery of the blanking opening. The fixed combination method of the collection box and the blanking opening is simple and easy to operate, which makes it easy to quickly combine the collection box with the blanking opening to collect and use the waste paper scraps produced by slotting and cutting. When the collection box and the blanking opening need to be separated later, the handles at both sides are pulled outward at the same time, and the outer ends of the limit rods are pulled out of the corresponding limit holes through the stretching of the springs, and then the limit rods are kept pulled outward. The collecting box can be slid vertically downward from the blanking opening to be separated, or can be slid forward from the back to be separated and then removed. The separation method of the collecting box and the blanking opening is simple and easy to operate, which is convenient for the later removal of the collecting box to completely clean out the concentrated waste paper scraps, and also convenient for regular cleaning and maintenance of the collecting box. When reinstalling the collecting box, the collecting box is picked up so that the outer periphery of the collecting box and the inner periphery of the blanking opening are vertically slidably matched, and at the same time, the pull handles at both sides are pulled outward again, and the collected paper scraps are stretched by the springs. The outer ends of the limiting rods are inserted into the corresponding mounting holes. When the material collecting box moves to the material collecting box at the material dropping opening until the top surface of the material collecting box is flush with the top surface of the material dropping opening and the outer rear part of the material collecting box is in contact with the inner rear part of the material dropping opening, it means that the limiting rods and the limiting holes are laterally coaxial again. Then, the handle is released, and the spring releases the stretched state at any time to drive the limiting rods to be laterally inserted into the corresponding limiting holes again, so as to complete the reinstallation and fixation of the material collecting box at the material dropping opening position.

[0019] The beneficial effects are as follows: 1. The utility model is provided with a limit stopper assembly on the pad at the front of the base to prevent the cardboards conveyed through the cardboard slotting line mechanism from scattering on the top surface of the pad, so that the front of the conveyed falling cardboards can be blocked and limited by the setting of the limit stopper assembly, and at the same time, side limiter assemblies are extended on both sides of the limit stopper assembly, so that the side of the conveyed falling cardboards can be blocked and limited by the setting of the side limiter assemblies, so as to prevent the cardboards from scattering on the pad after the cardboards are dropped, and it is convenient for workers to collect and take away the cardboards;

[0020] 2. The longitudinal position of the baffle can be adjusted by sliding the movable seat of the limit stop assembly along the longitudinal slide groove and by tightening the elastic pressure block at the bottom of the clamping stud to press on the bottom of the adjustment groove, so that the baffle can be adjusted to a suitable position in the longitudinal direction to block and limit the front of the cardboard being transported and dropped, thus enriching the general use range of the limit stop assembly and improving the use flexibility of the limit stop assembly;

[0021] 3. The distance between the limiting side plates at both sides can be adjusted by sliding the adjusting stud of the side limiting assembly laterally along the slide groove and tightening the limiting nut on the surface of the wing plate, so that the limiting side plates can be adjusted to a suitable position in the horizontal direction to block and limit the falling cardboard, thereby enriching the general use range of the side limiting assembly and improving the use flexibility of the side limiting assembly;

[0022] 4. A waste collection component for collecting waste paper scraps generated during the slotting and cutting process of the cardboard slotting line mechanism is provided at the position of the blanking opening of the cardboard slotting line mechanism, so that the waste paper scraps generated during the slotting and cutting process of the cardboard slotting line mechanism can be collected in a centralized manner through the collection box of the waste collection component, thereby avoiding the waste paper scraps being scattered on the top surface of the base and being inconvenient to collect and clean;

[0023] 5. The collection box is detachably fixed to the inner periphery of the blanking opening by means of vertical sliding cooperation between the collection box and the blanking opening and horizontal sliding cooperation between the limit rod and the limit hole. The fixed combination of the collection box and the blanking opening is simple and easy to operate, and then it is convenient to quickly combine the collection box with the blanking opening to collect and use the waste paper scraps generated by slotting and cutting;

[0024] 6. You only need to pull the limit rod out of the limit hole to make the collection box slide vertically from the blanking opening and remove it. The separation method of the collection box and the blanking opening is simple and easy to operate, which is convenient for the collection box to be disassembled later and the collected waste paper scraps to be completely cleared out. At the same time, it is convenient to regularly clean and maintain the collection box. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] See also Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the lower part of the cardboard slotting line mechanism 2 is equipped with a waste collection component 6 for collecting waste paper scraps generated during the slotting and cutting process of the cardboard slotting line mechanism 2. Specifically, the waste collection component 6 includes a collection box 602 with a material drop opening 601. The upper and lower parts and the front part of the material drop opening 601 of the cardboard slotting line mechanism 2 are open. The collection box 602 is a rectangular box body with the top and the front part open. The outer periphery of the collection box 602 is vertically slidably matched with the inner periphery of the material drop opening 601, and the front part of the collection box 602 is open. The front part of the paperboard slotting line mechanism 2 exceeds the front part of the blanking opening 601, and the front part of the paperboard slotting line mechanism 2 is fixed with fixed blocks 603 extending longitudinally at the positions on both sides of the blanking opening 601, and the fixed blocks 603 are provided with limited holes 606 in the horizontal direction, and the two sides of the collecting box 602 that exceed the front part of the blanking opening 601 are provided with mounting holes 608 in the horizontal direction, and the mounting holes 608 and the limited holes 606 are through holes, and the mounting holes 608 and the limited holes 606 are respectively coaxially opposed in the horizontal direction, and the mounting holes 608 are coaxially slidably matched with the limited holes 606 in the horizontal direction. The limiting rods 607 are positioned at the sides of the machine, and the outer ends of the limiting rods 607 at the two sides that are far away from each other are slidably matched with the corresponding limiting holes 606, and the inner ends of the limiting rods 607 at the two sides that are close to each other are extended out of the corresponding inner side of the collecting box 602 and are coaxially fixed with a pull handle 605. The part of the limiting rod 607 located between the corresponding pull handle 605 and the inner end face of the collecting box 602 is coaxially fitted with a spring 604, and the two ends of the spring 604 are respectively fixedly connected with the corresponding pull handle 605 and the inner end face of the collecting box 602. The purpose of such a setting is that, first, the waste paper scraps generated during the slotting and cutting process of the cardboard slotting line mechanism 2 can be collected through the collection box 602, and at the same time, the collection box 602 can be detachably fixed to the inner periphery of the blanking opening 601 by means of vertical sliding cooperation between the collection box 602 and the blanking opening 601 and horizontal sliding cooperation between the limit rod 607 and the limit hole 606, and the collection box 602 can be vertically slid away from the blanking opening 601 and removed after only pulling the limit rod 607 out of the limit hole 606.

[0046] See also Figure 1 , Figure 4 , Figure 7 and Figure 8 As shown, the limiting material stopper assembly 5 is optimized as follows: the adjusting groove 506 is a dovetail groove or an I-shaped groove, and the adjusting groove 506 is a blind groove in the longitudinal direction and is opened from front to back, so that the movable seat 502 can only slide longitudinally along the adjusting groove 506 and cannot escape from other directions. At the same time, the baffle 501 is a rectangular vertical plate and the top surface is not lower than the blanking position height of the paperboard slotting line mechanism 2. Such a configuration facilitates the baffle 501 to have a sufficient height in the vertical direction to block and limit the front part of the blanking paperboard.

[0047] Specifically, with regard to the positions of the elastic pressure block 507 and the clamping stud 504, the elastic pressure block 507 is a cylindrical rubber block and its outer diameter is smaller than the outer diameter of the clamping stud 504. The top of the clamping stud 504 is fixed with an end 503 for facilitating holding and applying force. The purpose of this arrangement is that during the process of the elastic pressure block 507 being pressed on the bottom of the adjusting groove 506, the elastic pressure block 507 can avoid pressure damage to the bottom of the adjusting groove 506 through its own buffering capacity, and can also improve the stability of the elastic pressure block 507 when being pressed and locked. Preferably, the end 503 is an outer hexagonal shape, so that the clamping stud 504 can be tightened or loosened smoothly by holding the end 503 and applying force.

[0048] See also Figure 1 , Figure 3 , Fig. 9 and Fig.10 As shown, the side limit assembly 7 is optimized as follows: the slide grooves 703 are all waist-shaped long grooves arranged in the transverse direction, the top surfaces of the limit side plates 701 are all flush with the top surfaces of the baffle plates 501, the limit side plates 701 are all rectangular vertical plates, and the front end surfaces are in contact with the rear end surfaces of the corresponding wing plates 702 on the same side but are not connected. The purpose of such an arrangement is, firstly, to facilitate the slide grooves 703 to have a sufficiently wide transverse adjustment range, and at the same time to facilitate the limit side plates 701 to have a sufficient height in the vertical direction to block and limit the side edges of the blanking paperboard.

[0049] Further optionally, the limit nuts 705 are all hand-tightened knurled nuts and the outer diameters are all larger than the vertical slot width of the adjusting slot 506, so that the limit nuts 705 can be directly grasped and forcefully tightened or loosened, and at the same time, the limit nuts 705 can be smoothly tightened on the front end surface of the wing plate 702. The front end of the adjusting stud 704 is coaxially fixed with a handle 706, so that the adjusting stud 704 can be driven to slide laterally along the slide slot 703 by grasping the handle 706 and applying force. At the same time, the setting of the handle 706 can also prevent the limit nut 705 from detaching from the front end of the adjusting stud 704.

[0050] See also Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the waste collection component 6 is optimized as follows: the top surface of the collection box 602 is flush with the top surface of the material drop opening 601, and the outer rear part of the collection box 602 is in close contact with the inner rear part of the material drop opening 601. The purpose of this arrangement is that during the cooperation between the collection box 602 and the material drop opening 601, when the limiting rod 607 moves with the collection box 602 to be horizontally coaxial with the limiting hole 606, an obvious prompt can be given by the top surface of the collection box 602 being flush with the top surface of the material drop opening 601 and the outer rear part of the collection box 602 being in close contact with the inner rear part of the material drop opening 601.

[0051] With the above structure, specifically in the process of using the cardboard slotting line, the cardboard is translated and transported to the cardboard slotting line mechanism 2 through the cardboard conveying mechanism 1 and is slotted by the cardboard slotting line mechanism 2. Since the pad 4 at the front of the base 3 is installed with a limit stop component 5 for preventing the cardboard that is transported through the cardboard slotting line mechanism 2 from scattering on the top surface of the pad 4, the setting of the limit stop component 5 can block and limit the front of the transported falling cardboard. Specifically, in operation, after holding the end 503 and reversing the pressing stud 504 counterclockwise to make the elastic pressing block 507 leave the bottom of the adjusting groove 506, the movable seat 502 of the limit stop component 5 slides longitudinally along the slide groove 703 and tightens the bottom of the pressing stud 504 by clockwise rotation. The elastic pressing block 507 at the end is pressed on the bottom of the adjusting groove 506 to adjust the longitudinal position of the baffle 501, so that the baffle 501 can be adjusted to a suitable position in the longitudinal direction to block and limit the falling cardboard at the front, thereby enriching the general use range of the limit stop component 5 and improving the use flexibility of the limit stop component 5. The baffle 501 can be adjusted to a suitable position with reference to the position state of the falling cardboard. After the baffle 501 is adjusted into place, the cardboard falling through the cardboard slotting line mechanism 2 can be blocked and limited at the front. At the same time, since the side limit components 7 are extended on both sides of the limit stop component 5, the side limit components 7 can be set to block the falling cardboard at the side. When the locking nut 705 is turned, the distance between the limiting side plates 701 at the two sides can be adjusted by turning the limiting nut 705 on the same side respectively. The limiting nut 705 on the same side can then be turned, and the distance between the limiting side plates 701 at the two sides can be adjusted by turning the limiting nut 705 on the two sides to the two sides. After the limiting side plates 701 are adjusted into place, the cardboards conveyed and dropped by the cardboard slotting line mechanism 2 can be blocked and limited on both sides. In this way, since the cardboards conveyed and dropped by the cardboard slotting line mechanism 2 are blocked and limited from the front and both sides respectively, the cardboards conveyed and dropped by the cardboard slotting line mechanism 2 can be prevented from scattering on the top surface of the pad 4, so that the workers can collect and remove the cardboards. Specifically, as to the position of the blanking opening 601 of the cardboard slotting line mechanism 2, since the cardboard slotting line mechanism 2 is provided with a waste collection component 6 for collecting waste paper scraps generated in the slotting and cutting process of the cardboard slotting line mechanism 2 at the position of the blanking opening 601, the workers can clean the waste paper scraps generated in the slotting and cutting process of the cardboard slotting line mechanism 2 into the collection box 602.In this way, the waste paper scraps generated during the slotting and cutting process of the cardboard slotting line mechanism 2 can be collected in a centralized manner through the collection box 602 of the waste collection assembly 6, thereby avoiding the waste paper scraps being scattered on the top surface of the base 3 and being inconvenient to collect and clean. Specifically, when the collection box 602 and the blanking opening 601 are combined, at the beginning, the outer periphery of the collection box 602 and the inner periphery of the blanking opening 601 are vertically slidably matched, and the limiting rod 607 and the limiting hole 606 are horizontally slidably matched. At this time, the collection box 602 and the blanking opening 601 are vertically slidably matched, and the limiting rod 607 and the limiting hole 606 are horizontally slidably matched. The combination method can make the collection box 602 detachably fixed to the inner periphery of the blanking opening 601. The fixed combination method of the collection box 602 and the blanking opening 601 is simple and easy to operate, and then it is convenient to quickly combine the collection box 602 with the blanking opening 601 to collect and use the waste paper scraps generated by slotting and cutting. When it is necessary to separate the collection box 602 and the blanking opening 601 later, the pull handles 605 at both sides are pulled outward at the same time, and the outer ends of the limiting rods 607 are pulled out of the corresponding limiting holes 606 by the way of being stretched by the springs 604, and then the limiting rods 607 are kept pulled outward to make the collection box 602 The material box 602 is detached by sliding vertically downward from the material-dropping opening 601 or sliding forward from the back to the front to be detached and then removed. The separation method of the material-dropping box 602 and the material-dropping opening 601 is simple and easy to operate, which is convenient for the collection box 602 to be disassembled and the collected waste paper scraps to be completely cleaned out at a later time, and it is also convenient for the collection box 602 to be regularly cleaned and maintained. When the collection box 602 is reinstalled, the collection box 602 is picked up so that the outer periphery of the collection box 602 and the inner periphery of the material-dropping opening 601 are vertically slidably matched, and at the same time, the pull handles 605 at the two sides are pulled outward again, and the limit rods 604 are stretched by the springs. 7, the outer ends of the collecting box 602 are all received into the corresponding installation holes 608. When the collecting box 602 moves to the top surface of the collecting box 602 at the blanking opening 601, and the outer rear part of the collecting box 602 is in contact with the inner rear part of the blanking opening 601, it means that the limiting rod 607 and the limiting hole 606 are again horizontally coaxial, and the handle 706 is released. The spring 604 releases the tension state at any time and drives the limiting rod 607 to be horizontally inserted into the corresponding limiting hole 606 again, so as to complete the reinstallation and fixation of the collecting box 602 at the blanking opening 601.
