Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of packaging machinery, in particular to a water-based adhesive tape machine core structure and adhesive tape machine convenient to wear. BACKGROUND

[0002] In the existing carton sealing equipment, the main material for sealing adhesive tape is BOPP (biaxially oriented polypropylene) and PVC (polyvinyl chloride). However, these materials have the problem of not being easy to degrade, causing great pollution to the environment. In addition, in the process of paper box recycling and remanufacturing, manual tearing of the adhesive tape is required, significantly increasing labor costs. Therefore, with the deepening of the concept of environmental protection, traditional plastic packaging materials are gradually being eliminated, especially in developed countries, this trend is more obvious.

[0003] To address this challenge, the skilled person in the art has developed a water-active adhesive tape (referred to as water-based adhesive tape) based on the concept of environmental protection. The tape uses degradable materials (such as water-based kraft paper adhesive tape), which can automatically generate adhesion when exposed to water, so that only water is needed to achieve adhesion during the packaging process, greatly simplifying the sealing operation and improving the convenience of paper box recycling.

[0004] For example, Chinese patent publication No. CN115743775A discloses a water-based adhesive tape automatic carton sealing machine core, the core structure of which includes a core frame, a paper disc for storing adhesive tape, an adhesive tape conveying mechanism for conveying adhesive tape, a cutting mechanism for cutting adhesive tape, and a liquid immersion mechanism fixed on the core frame. The liquid immersion mechanism is arranged between the cutting mechanism and the adhesive tape exit end, and includes a liquid storage container and a movable adhesive roller. The adhesive roller is partially immersed in the liquid storage container, and through contact with the adhesive tape during the conveying process, one side of the adhesive tape is uniformly stained with liquid, thereby achieving water-activated activation of the adhesive tape.

[0005] The above-mentioned scheme realizes automatic paper feeding, adhesive tape water brushing, adhesive tape cutting, and adhesive tape sticking and smoothing, effectively promoting the development of environmentally friendly carton packaging, and conforms to the green packaging concept of sustainable development. However, the prior art still has the following shortcomings:

[0006] 1. Complicated adhesive tape threading process: Although the core structure layout is coherent, when installing the water-based adhesive tape, the adhesive tape still needs to be threaded through each component in the traditional manner, which is complex and time-consuming to operate.

[0007] 2. Inaccurate adhesive tape length control: Due to the lack of precise length adjustment mechanism, the phenomenon of adhesive tape being too short or too long is likely to occur, affecting the sealing quality and efficiency.

[0008] Therefore, there is an urgent need for an improved water-based adhesive tape carton sealing equipment to further optimize the adhesive tape threading process, improve the accuracy of the adhesive tape length, and ensure the efficiency and environmental protection of the sealing process.

[0048] As shown, Figure 4 The cutter assembly 50 includes the fixed cutter 51 and the moving cutter 52 arranged on both sides of the belt conveying channel and the driving device 53 for driving the fixed cutter 51 and the moving cutter 52 to fold to cut the adhesive tape.

[0049] Specifically, the driving device 53 is a linearly telescopic air cylinder, the moving cutter 52 is in the form of a sheet and is horizontally fixed to the output rod of the air cylinder, when the output rod of the air cylinder is in the contracted state, the moving cutter 52 is located on one side of the belt conveying channel and does not protrude out of the belt conveying channel, the fixed cutter 51 is also in the form of a sheet and includes a fixed seat for fixing the moving cutter 52 to the bottom plate 11 and a lower cutter blade, the side of the fixed seat facing the moving cutter 52 is provided with a mounting groove (not labeled in the figure), the lower cutter blade is embedded in the mounting groove, and the upper and lower cutter blades are closely distributed in the vertical direction, when the moving cutter 52 extends to the position of the fixed cutter 51, the lower end surface of the moving cutter 52 closely contacts the upper end surface of the lower cutter blade, thereby facilitating the cutting of the water-based adhesive tape 90.

[0053] Alternatively, the air cylinder can be replaced by a screw rod mechanism or other mechanism or device with linear telescopic function, which is not limited herein.

[0054] As Figure 3 , 5 shown in the embodiment, the upper driving wheel 30 and the lower driving wheel 20 are respectively installed on the upper and lower sides of the moving knife 52, and the upper driving wheel 30 and the lower driving wheel 20 are on the same vertical plane and rotate parallel to each other, and the rotation shafts of the upper driving wheel 30 and the lower driving wheel 20 are hinged between the first panel 13 and the bottom plate 11 through the bearing 21.

[0055] The auxiliary compression wheel 40 is parallel to the lower driving wheel 20, and is slidingly arranged on the support 10 in the direction of approaching or moving away from the lower driving wheel 20.

[0056] Specifically, as Figure 5 shown, the bottom plate 11 is located in the second mounting area and opposite to the lower driving wheel 20, and is fixed with an L-shaped first mounting plate 54, and the first mounting plate 54 is locked and fixed with a linear telescopic first driving cylinder 55, and the output shaft of the first driving cylinder 55 is fixed with a second mounting plate 56 which is open towards the lower driving wheel 20 and is in the shape of “ ”, and the two side walls of the second mounting plate 56 are rotatably connected with a contact wheel 57, and when the first driving cylinder 55 is extended, the wheel surface of the contact wheel 57 is in contact with the wheel surface of the lower driving wheel 20, so as to drive the water-based adhesive tape 90 passing through it through the friction in the process of rotation, so as to continuously transmit it towards the other side of the tape running channel, and through the auxiliary compression wheel 40, the water-based adhesive tape 90 can be smoothly transmitted in the tape running channel in cooperation with the lower driving wheel 20.

[0057] As Figure 5 , 6 , 7 shown, the immersion liquid assembly 60 is opposite to the upper driving wheel 30, and includes a liquid storage tank 61 and a water-dipping roller 62 which is parallel to the upper driving wheel 30 and is used for transferring water in the liquid storage tank 61 to the roller surface of the upper driving wheel 30, and the immersion liquid assembly 60 is slidingly arranged on the support 10 in the direction of approaching or moving away from the upper driving wheel 30.

[0058] Specifically, as Figure 5 , 6 shown, the immersion liquid assembly 60 is slidingly connected to the support 10 through a cylinder device or a lead screw device, which is used to approach or move away from the upper driving wheel 30 to compress or release the adhesive tape, and in the embodiment, it is driven by a second driving cylinder 63, which is a sliding seat 64 type cylinder, and the side wall of the liquid storage tank 61 is locked and fixed on the sliding seat 64 of the second driving cylinder 63, so that the opening of the liquid storage tank 61 is upward and can move in the direction of approaching or moving away from the upper driving wheel 30 under the telescopic action of the second driving cylinder 63 cover the sliding seat 64.

[0059] In this embodiment, the liquid tank 61 is recessed downward on the side close to the upper driving wheel 30 so that the side wall thereof forms a lateral opening 611 facing the upper driving wheel 30. The water absorbing roller 62 is rotatably connected to the side wall on both sides of the lateral opening 611, and the lowest position of the water absorbing roller 62 is lower than the bottom of the lateral opening 611 and extends to a position close to the bottom of the liquid tank 61. The outer circumferential side of the water absorbing roller 62 extends to a position protruding from the lateral opening 611 so as to form a contact position beyond the liquid tank 61. When the second driving cylinder 63 is extended, the liquid tank 61 can drive the water absorbing roller 62 to move to a position in contact with the wheel surface of the upper driving wheel 30. At this time, the upper driving wheel 30 is just located on the contact position of the water absorbing roller 62, so that the water absorbing roller 62 is in contact with the upper driving wheel 30. When the water absorbing roller 62 rotates, the liquid in the liquid tank 61 can be transferred along the roller surface to the surface of the water-based adhesive tape 90 at the contact position, so as to activate the water-based adhesive tape 90 to generate adhesion, thereby facilitating subsequent packaging of the carton.

In cooperation with a corresponding temperature detection probe (not shown in the figure), the temperature of the water in the liquid tank 61 can be controlled to keep it at the most suitable temperature. When the water is delivered to the surface of the water-based adhesive tape 90, the water-based adhesive tape 90 can be quickly activated to generate adhesion. In this process, the water temperature in the liquid tank 61 is generally required to be higher than the optimal activation temperature, so as to offset the temperature loss in the delivery process.

[0062] In addition, a layer of sponge (not shown in the figure) is generally designed in the liquid tank 61 to filter the residual glue brought down by the water absorbing roller 62, so as to avoid the residual glue flowing into the liquid tank 61 and affecting the original state of the liquid.

[0063] Preferably, the water absorbing roller 62 is rotatably arranged on the side of the liquid tank 61 close to the upper driving wheel 30 and at least partially immersed below the liquid surface in the liquid tank 61.

[0064] Preferably, as shown in Figure 6 the liquid tank 61 is provided with a roll preventing plate 66 distributed above the water absorbing roller 62 and parallel to the belt passing channel. The lower end of the roll preventing plate 66 extends out a plurality of roll preventing strips 661, and a plurality of annular accommodation grooves 621 are arranged around the roller surface of the water absorbing roller 62. The roll preventing strips 661 at least partially penetrate into the accommodation grooves 621.

[0065] In the embodiment, the two sides of the anti-winding plate 66 extend vertically towards the same side to form a connecting edge 662, and the two connecting edges 662 are rotationally connected to the two side walls of the liquid storage groove 61, so that the angle and position of the anti-winding plate 66 can be adjusted, and the anti-winding strip 661 can smoothly enter the accommodation slot 621.

[0066] In the above process, when the water-based adhesive tape 90 is transmitted between the upper driving wheel 30 and the water roller 62, it is soaked by the water on the water roller 62, thereby activating the adhesive component on the water-based adhesive tape 90, and then the water-based adhesive tape 90 continues to be transported towards the opening position of the tape passage under the guidance of the anti-winding strip 661, so as to avoid the water-based adhesive tape 90 being wound into the liquid storage groove 61 along the water roller 62, and further improve the stability of the water-based adhesive tape 90 transportation.

[0067] Preferably, as shown in Figure 6 , 7 , the liquid storage groove 61 located below the water roller 62 is provided with a liquid collecting tank 67, one side of the liquid collecting tank 67 is provided with a liquid guide opening (not shown in the figure), which is used to collect excess liquid and guide the liquid to the outside, and the two sides of the liquid collecting tank 67 are also rotationally connected to the lower end of the liquid storage groove 61, and the opening of the liquid collecting tank 67 is opposite to the contact position of the water roller 62, so that when the excess water drops from the water roller 62 or flows down along the edge of the liquid storage groove 61, it can smoothly fall into the opening of the liquid collecting tank 67 for collection, and flow to the corresponding external collection container through the liquid guide opening, thereby avoiding the liquid with residual adhesive flowing into the internal structure of the machine core, affecting the normal operation of the machine core.

[0068] Preferably, as shown in Figure 7 , 8 , 9, the upper driving wheel 30 and the lower driving wheel 20 are driven to rotate by the stepping motor 22 or the servo motor, respectively. In the embodiment, the upper driving wheel 30 and the lower driving wheel 20 are driven to rotate by two stepping motors 22, respectively. The two stepping motors 22 are installed in the first mounting area 14, the output shaft of the stepping motor 22 extends through the bottom plate 11 to the back of the bottom plate 11, and the rotating shaft of the upper driving wheel 30 and the lower driving wheel 20 also extends through the bottom plate 11 to the back of the bottom plate 11. The rotating shaft and the corresponding output shaft are transmissionally connected through the synchronous belt mechanism 23, so that the double driving wheels and the stepping motor 22 can be driven to accurately control the feeding length of the water-based adhesive tape 90, effectively avoiding the problems of too short or too long adhesive tape, thereby significantly improving the quality and efficiency of carton packaging.

This design makes the water-based adhesive tape 90 can be directly inserted from the opening side of the tape passing channel, and then the adhesive tape is pressed accurately between the upper driving wheel 30 and the lower driving wheel 20 by moving the auxiliary pressing wheel 40 and the immersion liquid assembly 60, and the installation process is completed.
