Description

Technical Field

[0002] PVB interlayer is a translucent film, a polymer material formed by extrusion of polyvinyl butyral resin with plasticizer. It is a translucent film with no impurities, a flat surface, a certain degree of roughness and good softness. It has good adhesion to inorganic glass, and has the characteristics of transparency, heat resistance, cold resistance, moisture resistance, high mechanical strength, etc. It is the best adhesive material for manufacturing laminated and safety glass in the world. It is also widely used in building curtain walls, awnings, display windows, bank counters, prison visitor windows, steel furnace screens and various bulletproof glass.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] See also Figure 1 As shown, the present invention is a raw material crushing and processing equipment for the production of PVB intermediate film, including a support frame 1, a material receiving box 2 is fixedly arranged on the upper end of the support frame 1, a first crushing chamber 3 is fixedly arranged on the upper end of the material receiving box 2, the first crushing chamber 3 is communicated with the material receiving box 2, a support plate 101 is connected to the support frame 1, a second crushing chamber 4 is arranged on the upper end of the support plate 101, the second crushing chamber 4 is arranged corresponding to the bottom center of the material receiving box 2, a storage box 5 is arranged at the bottom end of the support plate 101, and the storage box 5 is fixedly installed on the support frame 1.

[0037] like Figure 2A plurality of discharge holes 301 are arranged at the bottom of the first crushing chamber 3, and linear slides 302 are symmetrically arranged on both sides of the first crushing chamber 3, and sliders 303 are slidably installed on the linear slides 302, and a crushing plate 304 is fixedly arranged between the two sliders 303, and crushing holes 3041 are arranged in an array on the crushing plate 304, and a plurality of cutting blades 3042 are circumferentially arranged on the inner wall of the crushing hole 3041, and first crushing blades 305 are arranged in an array on the inner walls of both sides of the first crushing chamber 3, and the first crushing blades 305 are arranged one-to-one corresponding to the crushing holes 3041.

[0038] Specifically, in order to carry out preliminary crushing of raw materials that have been agglomerated into blocks or large particles, by setting a crushing hole 3041 and a cutting blade 3042, the slider 303 will drive the crushing plate 304 to move back and forth along the linear slide 302. During this process, the crushing hole 3041 will reciprocate through the raw material, and the cutting blade 3042 will cut and crush the raw material, and cooperate with the first crushing blade 305 to crush the raw material that has been agglomerated into blocks or large particles, thereby realizing the preliminary crushing process. The crushed raw material will enter the receiving box 2 from the discharge hole 301.

[0039] like Figure 6 As shown, the second pulverizing chamber 4 is coaxially provided with an inner sleeve 401 and a middle sleeve 402, and the inner sleeve 401 and the middle sleeve 402 divide the second pulverizing chamber 4 from the inside to the outside into an annular primary pulverizing chamber 403, a secondary pulverizing chamber 404 and a tertiary pulverizing chamber 405, and the feeding port at the bottom end of the receiving box 2 is located directly above the primary pulverizing chamber 403, and a plurality of primary sieve holes 4031 are distributed in an annular array at the bottom of the primary pulverizing chamber 403, a plurality of secondary sieve holes 4041 are distributed in an annular array at the bottom of the secondary pulverizing chamber 404, and a plurality of tertiary sieve holes 4051 are distributed in an annular array at the bottom of the tertiary pulverizing chamber 405, and the primary sieve holes 4031 are distributed in an annular array at the bottom of the secondary pulverizing chamber 404, and the tertiary sieve holes 4051 are distributed in an annular array at the bottom of the tertiary pulverizing chamber 405. 031, the apertures of the secondary sieve holes 4041 and the tertiary sieve holes 4051 decrease successively. A rolling assembly 6 is arranged inside the second crushing chamber 4. The rolling assembly 6 includes a rotating shaft 601, a connecting rod 602 and a rolling rod 603. The rotating shaft 601 rotates coaxially with the second crushing chamber 4. The top of the rotating shaft 601 is fixedly connected to the connecting rod 602. There are three groups of rolling rods 603, and each group of rolling rods 603 is symmetrically distributed on both sides of the connecting rod 602 and extends into the corresponding crushing chamber. A rolling ball 604 is rotatably installed at the bottom of the rolling rod 603, and the rotating shaft 601 drives the rolling ball 604 to perform a rotating ball milling action in the corresponding crushing chamber.

[0040] Specifically, the raw materials after preliminary crushing will fall into the primary crushing chamber 403, and the rotating shaft 601 will drive the three groups of crushing rods 603 to rotate continuously in the corresponding crushing chamber, so that the crushing balls 604 crush the raw materials, and after being crushed by the rotating crushing balls 604, the raw materials enter the secondary crushing chamber 404 from the primary sieve hole 4031 to continue crushing and crushing, and so on and finally enter the tertiary crushing chamber 405 to crush and crush. Since the apertures of the primary sieve holes 4031, the secondary sieve holes 4041 and the tertiary sieve holes 4051 decrease step by step, the degree of crushing of the raw materials will also be refined step by step. The primary crushing chamber 403, the secondary crushing chamber 404 and the tertiary crushing chamber 405 will achieve different degrees of crushing on the raw materials, so that three kinds of raw materials with different fineness after crushing can be obtained.

[0041] like Figure 3 As shown, slide grooves 306 are symmetrically arranged on both sides inside the first crushing chamber 3, and a top plate 307 is slidably installed in the slide groove 306. The top plate 307 closes the upper end opening of the first crushing chamber 3, and a telescopic cylinder 308 is fixedly arranged on the top plate 307. The output shaft of the telescopic cylinder 308 is connected to the pressure plate 309, and the second crushing blades 310 are distributed in an array at the bottom of the pressure plate 309.

[0042] Specifically, since the crushing hole 3041 and the cutting blade 3042 can only cut and crush the raw material in the horizontal direction, the cutting effect of the raw material may be less than ideal. At this time, the crushing plate 304 is used to push the raw material to one side of the first crushing chamber 3, and the telescopic cylinder 308 is started to push the pressing plate 309 and the second crushing blade 310 to cut and crush the raw material in the vertical direction to improve the crushing effect of the raw material.

[0043] like Figure 7 As shown, a conical material blocking platform 406 is fixedly arranged between the bottom of the inner sleeve 401 and the middle sleeve 402 and between the middle sleeve 402 and the second crushing chamber 4.

[0044] Specifically, when the raw material passes through the primary sieve hole 4031, it will directly fall onto the inclined cone surface of the conical material blocking platform 406. The conical material blocking platform 406 will guide the raw material to the rolling path of the rolling ball 604. During the rolling process, part of the raw material will be pushed to the conical material blocking platform 406. At this time, the inclined surface structure of the conical material blocking platform 406 will make the raw material slide back onto the rolling path to facilitate multiple reciprocating rolling of the raw material. The same is true when the raw material passes through the secondary sieve hole 4041, thereby improving the rolling and crushing efficiency of the raw material.

[0045] like Figure 7 As shown, the rolling assembly 6 also includes a rolling motor 605 , which is fixedly arranged at the bottom center of the second crushing chamber 4 , and the output end of the rolling motor 605 is fixedly connected to the rotating shaft 601 .

[0046] like Figure 8 As shown, a semi-spherical cylinder 6031 is extended from the bottom of the rolling rod 603, and the rolling ball 604 is rotatably installed in the semi-spherical cylinder 6031. A mounting groove is provided in the semi-spherical cylinder 6031, and a pressure block 6032 is provided in the mounting groove. The top of the pressure block 6032 is connected to the mounting groove through an extrusion spring 6033, and a pressing bead 6034 is rotatably installed on the bottom end of the pressure block 6032, and the bottom end of the pressing bead 6034 presses against the top of the rolling ball 604.

[0047] It should be noted that the lengths of the three groups of rolling rods 603 in this embodiment are different, and will be selected according to the different depths of the corresponding crushing chambers to ensure that the rolling balls 604 at the bottom of each group of rolling rods 603 can abut against the bottom of the corresponding crushing chamber. During the rolling process, the rolling motor 605 is started, and the three groups of rolling rods 603 are driven to rotate continuously through the rotating shaft 601, and the three groups of rolling balls 604 will also synchronously perform the rotating rolling process. During the rotating rolling process of the rolling balls 604, the squeezing spring 6033 will squeeze the pressing block 6032, so that the pressing ball 6034 always abuts against the rolling ball 604, and the pressing ball 6034 and the rolling ball 604 are in point contact. The rolling ball 604 will always be subjected to the pressure of the pressing ball 6034 while rotating normally, thereby ensuring that the rolling ball 604 always has sufficient rolling pressure, thereby improving the rolling and crushing effect.

[0048] like Figure 4 and Figure 5 As shown, a dredging assembly 7 is provided inside the material receiving box 2, and the dredging assembly 7 includes a double-acting cylinder 701, and the double-acting cylinder 701 is fixedly provided on a bracket 702, and the bracket 702 is provided above the unloading port at the bottom end of the material receiving box 2, and an upper connecting plate 703 is fixedly provided on the top of the output shaft of the double-acting cylinder 701, and a sleeve rod 704 is evenly connected around the upper connecting plate 703, and a telescopic rod 705 is slidably installed in the sleeve rod 704, and the telescopic rod 705 is connected to the sleeve rod 704 by a spring, and a flexible scraper 706 is fixedly provided on the end of the telescopic rod 705, and the flexible scraper 706 abuts against the inner walls of the four sides of the material receiving box 2, and a lower connecting plate 707 is fixedly provided on the bottom end of the output shaft of the double-acting cylinder 701, and a dredging plate 708 is evenly connected around the lower connecting plate 707, and a dredging rod 709 is fixedly provided on the upper end of the dredging plate 708.

[0049] Specifically, when the raw materials after preliminary crushing fall into the receiving box 2 in large quantities at one time, it may cause the discharge port at the bottom of the receiving box 2 to be blocked. At the same time, during the discharge process, the raw materials may also adhere to the side wall of the receiving box 2, resulting in insufficient discharge. By setting up the dredging component 7, the double-acting cylinder 701 is used to drive the upper connecting plate 703 and the lower connecting plate 707 to reciprocate up and down. On the one hand, the upper connecting plate 703 will drive the sleeve rod 704 to rise and fall synchronously when it reciprocates. Due to the elastic connection between the sleeve rod 704 and the telescopic rod 705, the flexible scraper 706 will always be close to the side wall of the receiving box 2 under the action of elastic force. When the sleeve rod 704 moves up and down, the flexible scraper 706 will scrape the raw materials adhered to the side wall of the receiving box 2 back and forth to achieve sufficient discharge. On the other hand, when the lower connecting plate 707 reciprocates, it will drive the dredging rod 709 to stir up and down at the discharge port position, which can avoid the blockage of the raw materials at the discharge port position.

[0050] like Fig. 9 As shown, an annular partition is provided in the storage box 5, and the annular partition divides the storage box 5 into a primary storage chamber 501, a secondary storage chamber 502 and a tertiary storage chamber 503 from the inside to the outside. The bottom of the primary crushing chamber 403 is connected with the primary storage chamber 501 through a guide pipe 1 4032, the bottom of the secondary crushing chamber 404 is connected with the secondary storage chamber 502 through a guide pipe 2 4042, and the tertiary crushing chamber 405 is connected with the tertiary storage chamber 503 through a tertiary sieve hole 4051.

[0051] like Fig. 9 As shown, the first-level storage chamber 501 is connected to a discharge pipe 1 504, the second-level storage chamber 502 is connected to a discharge pipe 2 505, and the third-level storage chamber 503 is connected to a discharge pipe 3 506. The discharge pipe 1 504, the discharge pipe 2 505 and the discharge pipe 3 506 are coaxially arranged.

[0052] Specifically, the raw materials after rolling and crushing in the first-level crushing chamber 403 can directly fall into the first-level storage chamber 501 through the guide pipe 4032, the raw materials after rolling and crushing in the second-level crushing chamber 404 can directly fall into the second-level storage chamber 502 through the guide pipe 4042, and the raw materials in the tertiary crushing chamber 405 can fall into the tertiary storage chamber 503 through the third-level sieve hole 4051 after rolling and crushing. The fineness of the raw materials after crushing is different in different rolling stages, so that graded discharging and collection can be achieved according to different degrees of rolling and crushing, and the raw material collection and discharging processes of different storage chambers are independent of each other and do not interfere with each other.

[0053] The working principle of the above equipment is as follows: when in use, the PVB interlayer raw material is poured into the first crushing chamber 3, and the slider 303 moves back and forth along the linear slide 302, so that the crushing hole 3041 on the crushing plate 304 passes through the raw material back and forth, and the cutting blade 3042 is used in conjunction with the first crushing blade 305 to preliminarily crush the raw material that has condensed into blocks or large particles, and the telescopic cylinder 308 is started to push the pressing plate 309 and the second crushing blade 310 to cut and crush the raw material in the vertical direction. When the preliminarily crushed raw material falls into the receiving box 2, the double-acting cylinder 701 drives the upper connecting plate 703 and the lower connecting plate 707 to reciprocate up and down, and the flexible scraper 706 will scrape the raw material adhering to the side wall of the receiving box 2 back and forth, and at the same time, the dredging rod 709 stirs up and down at the discharge port position to avoid blockage of the raw material at the discharge port position, and the raw material will pass through the discharge port. The raw materials fall into the first-level crushing chamber 403, and the rotating shaft 601 will drive the three groups of crushing rods 603 to rotate continuously in the corresponding crushing chamber, so that the crushing balls 604 crush the raw materials, and after being crushed by the rotating crushing balls 604, they enter the second-level crushing chamber 404 from the first-level sieve hole 4031 to continue crushing and crushing, and so on and finally enter the tertiary crushing chamber 405 to be crushed and crushed. The raw materials after crushing in the first-level crushing chamber 403 can directly fall into the first-level storage chamber 501 through the guide pipe 4032, and the raw materials after crushing in the second-level crushing chamber 404 can directly fall into the second-level storage chamber 502 through the guide pipe 2 4042, and the raw materials in the tertiary crushing chamber 405 can fall into the tertiary storage chamber 503 through the third-level sieve hole 4051 after crushing, so as to realize graded discharging and collection according to different crushing degrees.

[0054] The present invention also provides a processing method of raw material crushing processing equipment for producing PVB interlayer, comprising the following steps:

[0055] Step 1: Preliminary crushing: Pour the PVB interlayer raw material into the first crushing chamber 3, drive the slider 303 to move back and forth along the linear slide 302, so that the crushing holes 3041 on the crushing plate 304 pass through the raw material back and forth, and use the cutting blade 3042 and the first crushing blade 305 to preliminarily crush the raw material that has condensed into blocks or large particles;

[0056] Step 2, fine ball grinding, the raw material after preliminary grinding falls into the primary grinding chamber 403 through the material receiving box 2, and after being rolled by the rolling balls 604, it enters the secondary grinding chamber 404 from the primary sieve hole 4031 to continue to be rolled and crushed, and so on and finally enters the tertiary grinding chamber 405 to be rolled and crushed, the apertures of the primary sieve hole 4031, the secondary sieve hole 4041 and the tertiary sieve hole 4051 decrease step by step, realizing a step-by-step fine grinding process;

[0057] Step three, graded discharge. The raw materials that have been crushed to different degrees in the primary crushing chamber 403, the secondary crushing chamber 404 and the tertiary crushing chamber 405 can fall into the corresponding chambers inside the storage box 5 at different crushing stages, so as to realize graded discharge and collection according to different crushing degrees.

[0058] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
