Description

Technical Field

[0001] This utility model relates to hot melt adhesives, and in particular to a cutting and forming device for high-adhesion EVA hot melt adhesive blocks. Background Technology

[0002] Hot melt adhesive is a solid adhesive, usually in block or granule form, and is widely used in industrial production and handicrafts.

[0003] During the production of hot melt adhesive blocks, the molten fluid hot melt adhesive is extruded from the extrusion tube and cut by a cutter. It then falls onto the conveying device and is cooled and shaped by water cooling. During long-term use, hot melt adhesive will inevitably remain on the surface of the cutter. If too much of this residual hot melt adhesive accumulates on the cutter surface, it can easily affect the cutting effect of the cutter, resulting in irregular shapes of the hot melt adhesive blocks.

[0004] To address the above issues, we propose a cutting and forming device for high-adhesion EVA hot melt adhesive blocks. Utility Model Content

[0005] This invention proposes a cutting and forming device for high-adhesion EVA hot melt adhesive blocks, which solves the above-mentioned problems existing in the use of the prior art.

[0006] The technical solution of this utility model is implemented as follows: a cutting and forming device for high-adhesion EVA hot melt adhesive blocks includes a cooling box, a cooling chamber is provided inside the cooling box, an extrusion pipe is provided above the cooling box, the lower side of the extrusion pipe extends into the cooling chamber, a conveyor belt is provided inside the cooling chamber, a number of shower heads are provided above the conveyor belt, and a cutter that can move left and right is installed inside the cooling chamber.

[0007] The cooling chamber is equipped with a scraper that can move back and forth.

[0008] A further feature of this invention is that a cylinder is installed inside the left side wall of the cooling chamber, a slide block is fixedly provided at the end of the piston rod of the cylinder, and the cutter is fixedly provided on the slide block;

[0009] The front and rear sides of the slide block abut against the front and rear side walls of the cooling chamber, respectively.

[0010] A further feature of this invention is that two lead screws are symmetrically and rotatably connected between the front and rear sidewalls of the cooling chamber.

[0011] Scraper seats are fixed on both the upper and lower sides of the scraper, and the two scraper seats are respectively threaded to the lead screw on the same side;

[0012] The scraper has a through groove running from front to back, and the edge of the groove abuts against the upper and lower sides of the cutter.

[0013] A further feature of this invention is that a mounting seat is fixedly provided on the rear side of the scraper seat on the lower side, and the mounting seat is threadedly connected to the lead screw on the lower side.

[0014] A collection box is detachably installed on the lower side of the mounting base. The collection box has an upward-facing collection groove and is located directly below the scraper.

[0015] A further feature of this invention is that a through hole is provided in the mounting base from front to back, and a bolt is provided in the through hole, the bolt being threaded into the rear side wall of the collection box.

[0016] A further feature of this invention is that the bottom wall of the collection tank has several drainage outlets extending through it.

[0017] A further feature of this invention is that: a mounting box is installed on the rear side of the cooling box, and the rear sides of the two lead screws are rotatably connected to the mounting box; a motor for driving the lead screws is installed on the mounting box.

[0018] Both motors are equipped with synchronous pulleys, and a synchronous belt connects the two synchronous pulleys.

[0019] A further feature of this invention is that the shower head includes several straight nozzles, angled nozzles, and two horizontal nozzles;

[0020] A mounting frame is fixedly provided on the upper side of the cooling box. Several direct nozzles are linearly and equidistantly fixed inside the upper side wall of the mounting frame. The angled nozzle is fixed on the left side of the upper side wall of the mounting frame and aligned with the discharge port of the extrusion tube.

[0021] The two horizontal nozzles are symmetrically fixed in the front and rear side walls of the cooling chamber and are positioned opposite the discharge port of the extrusion tube.

[0022] In summary, the beneficial effects of this utility model are as follows:

[0023] After prolonged use, the cutter surface is covered with a thick layer of hot melt adhesive. When it is necessary to clean the surface, move the cutter away from the extrusion tube, and then the scraper located at the front moves backward to scrape off the residual hot melt adhesive on the cutter surface. The scraped hot melt adhesive falls into the collection box to prevent this hot melt adhesive from being transported to other equipment along with the hot melt adhesive block.

[0024] If the blade of the cutter becomes dull, it can be sharpened with a scraper to ensure the cutting effect.

[0025] If the collection box is full of hot melt adhesive, technicians can loosen the bolts to remove the collection box and remove the hot melt adhesive for further processing. Attached Figure Description

[0034] The following will refer to the appendix in the embodiments of this utility model. Figure 1-6 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] Example:

[0036] like Figures 1 to 6 As shown, a cutting and forming device for high-adhesion EVA hot melt adhesive blocks includes a cooling box 11, with a cooling chamber 12 inside the cooling box 11. An extrusion pipe 13 connected to an extrusion device (not shown) is disposed above the cooling box 11, and the lower side of the extrusion pipe 13 extends into the cooling chamber 12. A conveyor belt 19 is disposed inside the cooling chamber 12, and several shower heads 20 connected to a water supply device (not shown) are disposed above the conveyor belt 19. A cylinder 17 is installed inside the left side wall of the cooling chamber 12. The cylinder 17... A slide block 18 is fixedly provided at the end of the stopper rod, and the cutter 14 is fixedly provided on the slide block 18. The front and rear sides of the slide block 18 respectively abut against the front and rear side walls of the cooling chamber 12. The slide block 18 drives the cutter 14 to move to the right under the drive of the cylinder 17, thereby cutting the hot melt adhesive extruded from the extrusion tube 13 into blocks. The cut hot melt adhesive blocks fall onto the conveyor belt 19 and are transported to the equipment of the next process through the conveyor belt 19. During the transport process, the shower head 20 sprays water to cool the hot melt adhesive blocks, thereby cooling and shaping them.

[0037] The shower head 20 includes several straight nozzles 34, angled nozzles 35, and two horizontal nozzles 36. A mounting bracket 37 is fixed on the upper side of the cooling box 11. The angled nozzles 35 are fixed on the left side of the upper side wall of the mounting bracket 37 and aligned with the outlet of the extrusion tube 13. When the extrusion tube 13 extrudes hot melt adhesive blocks, the two horizontal nozzles 36 are symmetrically fixed in the front and rear side walls of the cooling chamber 12 and spray the outlet of the extrusion tube 13. The horizontal nozzles 36 and the angled nozzles 35 spray and cool the surface of the hot melt adhesive blocks when the extrusion tube 13 extrudes the hot melt adhesive blocks to accelerate the solidification and forming speed of the surface, thereby making the hot melt adhesive have a regular shape.

[0038] Several direct spray nozzles 34 are equidistantly and linearly fixed inside the upper side wall of the mounting frame 37. When the hot melt adhesive block falls onto the conveyor belt 19 and is transported to the right, the hot melt adhesive block is sprayed and cooled to ensure that its interior is completely solidified.

[0039] It should be noted that the attached drawings only show part of the equipment on the hot melt adhesive block production line. The shower head 20 shown in the attached drawings is only part of the water cooling device in the hot melt adhesive block production line. It does not mean that the water cooling device in the hot melt adhesive block production line is only the number shown in the attached drawings. In addition, the cooling chamber 12 is provided with flowing water (not shown in the figure) with the liquid level higher than the upper side of the conveyor belt 19. While buffering the falling hot melt adhesive blocks, the flowing water can also cool the lower side of the hot melt adhesive blocks that cannot be sprayed by the shower head 20 during the transportation of the hot melt adhesive blocks.

[0040] Furthermore, two lead screws 21 are symmetrically rotatably connected between the front and rear side walls of the cooling cavity 12. Two scraper seats 22 are threadedly connected to the two lead screws 21 respectively. The two scraper seats 22 are symmetrically arranged vertically. A scraper 15 is fixedly provided between the two scraper seats 22. A scraper groove 23 is opened in the scraper 15, and the edge of the scraper groove 23 abuts against the upper and lower side surfaces of the cutter 14.

[0041] The two lead screws 21 are driven as follows: a mounting box 29 is installed on the rear side of the cooling box 11, and the rear sides of the two lead screws 21 are rotatably connected to the mounting box 29. A motor 30 for driving the lead screws 21 is installed on the mounting box 29. A synchronous pulley 31 is fixed on each of the two lead screws 21, and a synchronous belt 32 is connected between the two synchronous pulleys. When the motor 30 drives the lead screw 21 on one side to rotate, the synchronous pulley 31 on the same side drives the synchronous pulley 31 on the other side to rotate synchronously through the synchronous belt 32, so that the two lead screws 21 can rotate synchronously.

[0042] The working principle of this embodiment is as follows: After the cutter 14 has been cutting for a long time, its surface is covered with a certain thickness of irregularly shaped hot melt adhesive that has been cooled and formed. At this time, the cutter 14 moves to the left and away from the extrusion tube 13. Then, the scraper 15 moves backward under the drive of the two lead screws 21, so that the edge of the scraper groove 23 scrapes over the upper and lower sides of the cutter 14, thereby scraping off the hot melt adhesive remaining on the surface of the cutter 14 and avoiding affecting the cutting effect of the cutter 14 on the hot melt adhesive block.

[0043] Furthermore, the scraper 15 can also sharpen the cutter 14 to ensure that the blade of the cutter 14 remains sharp, thereby further ensuring the cutting effect of the cutter 14 on the hot melt adhesive.

[0044] Based on Embodiment 1, Embodiment 2 is proposed: A mounting base 24 is fixedly provided on the rear side of the lower scraper seat 22. The mounting base 24 is threadedly connected to the lower lead screw 21. A through hole 26 is provided through the lower mounting base 24, and a bolt 27 is provided in the through hole 26. A collection box 25 is provided on the lower side of the mounting base 24. The collection box 25 is located directly below the scraper 15. A collection groove 28 with an upward opening is provided in the collection box 25. The bolt 27 is threadedly connected to the lower scraper seat 22. Inside the rear wall of the collection box 25, the hot melt adhesive scraped by the scraper 15 falls into the collection trough 28 to prevent it from falling onto the conveyor belt 19 and being transported to the next process along with the hot melt adhesive block. When the collection trough 28 is full of hot melt adhesive, the technician can remove the collection box 25 by loosening the bolt 27 and empty the hot melt adhesive in the collection trough 28. In addition, several drain holes 33 are provided through the bottom wall of the collection trough 28 to allow the water in the collection trough 28 to be drained.
