DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides a technical solution: a quantitative cutting mechanism for producing hot melt adhesive strips, comprising: a base 1 with a working system installed inside, an upper cover 2 is arranged on the left side of the upper end of the base 1, and the contact surface between the base 1 and the upper cover is provided with adhesive strip fixing grooves 3 in an array shape, and the right side of the upper end of the base 1 and the right side of the upper cover 2 are both rotatably connected with a transmission roller 4, and an adhesive strip pushing groove 5 is arranged around the outer side of the transmission roller 4 and at a position opposite to the adhesive strip fixing groove 3, and a transmission belt 6 is sleeved on the outer sides of the front and rear ends of the two transmission rollers 4, and the right side of the front surface of the base 1 is connected with Motor 7, the output end of the motor 7 is fixedly connected to the front end of the lower end driving roller 4, the left side of the upper end of the base 1 is connected to a hydraulic support 8, the upper end of the hydraulic support 8 is connected to a hydraulic 9, the inside of the hydraulic support 8 is connected to a cutting knife 10, the upper surface of the cutting knife 10 is connected to a connecting plate 11, the output end of the hydraulic press 9 passes through the hydraulic support 8 and is fixedly connected to the upper surface of the cutting knife 10, the left side of the front surface of the base 1 is connected to a control panel 12, the control panel 12 is electrically connected to the control system inside the base 1, the motor 7, and the hydraulic press 9.

[0025] When in use, the hot-melt adhesive strip is pulled between the adhesive strip pushing grooves 5, and the corresponding parameters are input into the control panel 12 according to the required length, and the quantitative cutting mechanism for producing the hot-melt adhesive strip is started. The motor 7 rotates to drive the lower end transmission roller 4 to rotate, and the upper end transmission roller 4 is pulled by the transmission belt 6 to rotate together. At this time, the hot-melt adhesive strip will be pushed to the left to the inside of the adhesive strip fixing groove 3 opened between the base 1 and the upper cover 2, and continue to be pushed forward. When the set start time of the hydraulic press 9 is reached, the telescopic end of the hydraulic press 9 extends downward, pushing the cutting knife 10 and the connecting plate 11 to move downward together to cut the hot-melt adhesive strip.

[0026] like Figure 1-3 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, a guide block 21 is connected to the right side of the upper surface of the base 1, and a guide groove 22 is provided on the upper surface of the guide block 21. The center of the guide groove 22 is parallel to the two transmission rollers 4, and a chamfer is provided at the edge of the guide groove 22.

[0027] From the analysis of the above structure, it can be seen that the hot-melt adhesive strip at the rear is first pulled to the upper end of the guide slot 22, and then pulled between the adhesive strip pushing slots 5, which guides the hot-melt adhesive strip and prevents the position from shifting. The chamfers at the edges of the guide slot 22 can prevent the hot-melt adhesive strip from being scratched.

[0028] like Figure 1-2 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, guide plates 23 are connected to the left and right sides of the lower end of the hydraulic support 8.

[0029] It can be seen from the analysis of the above structure that when the cutting knife 10 falls downward, the guide plate 23 can guide the cutting knife 10 to prevent the position from being shifted.

[0030] like Figure 1-2 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, a tool groove 24 is opened on the left side of the upper surface of the base 1 and located at the lower end of the cutting knife 10.

[0031] From the analysis of the above structure, it can be known that when the cutting knife 10 cuts downwards, it can cut into the inside of the cutting knife groove 24, thereby ensuring that the hot melt adhesive strip can be completely removed.

[0032] like Figure 1-4 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, a material removal guide plate 25 is connected to the left surface of the base 1, and the lower end of the inner part of the material removal guide plate 25 is inclined forward.

[0033] From the analysis of the above structure, it can be known that after being cut, the hot melt adhesive strip will fall onto the upper surface of the material discharge guide plate 25 and then slide out through the forward slope.

[0034] like Figure 1-3 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, a rubber anti-slip strip is attached to the outer surface of the rubber strip pushing groove 5.

[0035] From the analysis of the above structure, it can be known that the rubber anti-skid strip attached to the outer surface of the rubber strip pushing groove 5 can increase the friction between the rubber strip pushing groove 5 and the hot melt adhesive strip when the driving roller 4 rotates.

[0036] like Figure 1-5As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, hydraulic rods 26 are connected to the front and rear ends of the base 1, and the upper output end of the hydraulic rod 26 is fixedly connected to the lower surface of the upper cover 2. Slide rails 27 are provided at the front and rear ends of the right side of the base 1, and a slider 28 is inserted and connected to the inside of the slide rail 27. The upper end of the slider 28 is connected to a roller 29 by bolts.

[0037] From the analysis of the above structure, it can be known that if the processed hot melt adhesive strip has a larger diameter, the transmission belt 6 is removed and replaced with a longer transmission belt 6, the slider 28 is inserted into the interior of the slide rail 27, and the transmission belt 6 is sleeved on the roller 29 and the transmission roller 4, and then the lower end of the roller 29 is fixed to the upper end of the slider 28 by bolts, and then the hydraulic rod 26 is started to move the upper cover 2 together with the transmission roller 4 at the upper end, and then the slider 28 is pulled backward, and after the transmission belt 6 is tightened, it is fixed at the left and right ends by bolts. At this time, the distance between the transmission roller 4, the base 1 and the upper cover 2 increases, so that a hot melt adhesive strip with a larger diameter can pass through.

[0038] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
