Description

Technical Field

[0001] The utility model belongs to the technical field of packaging material production, in particular to a raw material crusher for wear-resistant packaging materials. Background Art

[0002] Take woven bags as an example. Woven bags are also called snakeskin bags. Their raw materials are generally polyethylene, polypropylene and other chemical plastic raw materials. They are a type of plastic bag used for packaging. In industrial production, woven bags are used in a wide range of scenarios and have certain requirements for wear resistance. For example, in terms of packaging bags for various industrial and agricultural products, woven bags need to be wear-resistant during storage and transportation to prevent damage during handling and stacking. This type of packaging material is also supported by various raw materials. For example, woven bags are made of chemical plastics such as polyethylene and polypropylene through crushing, granulation, drawing, and weaving. Therefore, the crushing of raw materials is necessary. Crushing requires the use of relevant crushers, etc., but conventional crushers have the following disadvantages in actual use:

[0003] First of all, the crusher can crush the raw materials into small particles by cutting, grinding, etc. However, if the cutting method is used for crushing large pieces of raw materials, it is easy to wear the blades, and the raw materials will impact the blades, which will easily increase the load on the blades and reduce their service life. Therefore, for the crushing of large pieces of raw materials, there is a lack of certain pre-treatment functions.

[0004] One-time crushing will always lead to incomplete crushing, so repeated crushing is required, which leads to reduced efficiency, prolonged crushing time, and inability to quickly obtain raw materials with the required particle size. Utility Model Content

[0005] The purpose of the utility model is to provide a raw material crusher for wear-resistant packaging materials. By arranging a crushing cylinder, a crushing roller, a first crushing tooth, a second crushing tooth, a crushing shell, a wheel, a crushing knife, and a screen, the utility model solves the problems of lack of pretreatment function for bulk raw materials and the inability to quickly obtain raw materials of the required particle size by one-time crushing.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a raw material crusher for wear-resistant packaging materials, comprising a crushing cylinder, a first workbench, a second workbench, a crushing shell and a feeding cylinder. The lower portion of the crushing cylinder is fixed to a first chamber inside the first workbench. A crushing roller is rotatably arranged in the crushing cylinder, and crushing teeth 1 distributed in an annular array are fixed on the inner wall of the crushing cylinder. Crushing teeth 2 distributed in an annular array are fixed on the outer peripheral surface of the lower middle portion of the crushing roller.

[0008] The second workbench is located on one side of the first workbench, and a through chamber 2 is opened in the second workbench. A crushing shell is fixed in the second chamber, and a second motor is fixed on the upper end of the crushing shell. The output shaft of the second motor passes through the crushing shell downward and extends into the inner cavity of the crushing shell. A wheel is fixed therein, and crushing knives distributed in a ring array are fixed on the outer circumference of the wheel.

[0009] A feeding barrel is fixed through the upper end of the crushing shell, and a piston is provided in the feeding barrel to move up and down;

[0010] A screen is fixed on the bottom surface of the workbench below the second chamber.

[0011] Furthermore, the four corners of the bottom of the workbench 1 are all fixed with support legs 1, and the four corners of the bottom of the workbench 2 are all fixed with support legs 2. The support legs 1 are higher than the support legs 2, and the workbench 1 is higher than the workbench 2.

[0012] Furthermore, an inverted U-shaped bracket is fixed to the upper part of the outer periphery of the grinding cylinder, and a motor 1 is fixed to the top of the bracket. The output shaft of the motor 1 passes downward through the bracket and is fixed with a rotating shaft, and the bottom end of the rotating shaft is rotatably connected to a support bar fixed inside the chamber 1.

[0013] Furthermore, a crushing roller is fixed to the outer periphery of the part of the rotating shaft extending into the crushing cylinder, and the upper part of the crushing roller is a truncated cone structure, and the lower part of the crushing roller is a cylindrical structure. The crushing teeth 1 and the crushing teeth 2 do not contact each other, and the crushing teeth 1 and the crushing teeth 2 are staggered when viewed from above, and are distributed in order of high and low when viewed from the front.

[0014] Furthermore, a lower hopper is fixed on the bottom surface of a workbench below the chamber, and a lower feeding pipe is fixed through the bottom end of the lower hopper, and the lower end of the lower feeding pipe is connected to the side of the feeding barrel.

[0015] Furthermore, a cylinder is fixed to the upper end of the feed barrel, and a piston rod at the telescopic end of the cylinder passes downward through the feed barrel and is fixedly connected to the upper end of the piston in the feed barrel.

[0016] Furthermore, the height of the piston is higher than the diameter of the discharge pipe.

[0017] The utility model has the following beneficial effects:

[0018] The utility model solves the problem of lack of pre-processing function for bulk raw materials by arranging a crushing cylinder, a crushing roller, a first crushing tooth and a second crushing tooth. First, the bulk raw materials enter the crushing cylinder and enter the gap between the crushing roller and the crushing cylinder along the curved surface of the upper part of the crushing roller. At this time, the crushing roller rotates at a high speed, and the raw materials continuously contact the first crushing tooth and the second crushing tooth, which are quickly crushed and the bulk materials are quickly crushed into small particles that can pass through the gap between the first crushing tooth and the second crushing tooth, thus realizing pre-processing crushing operation and avoiding the problem that the materials are too large to be conveniently cut and crushed.

[0019] The utility model solves the problem that the raw materials of the required particle size cannot be quickly obtained by one-time crushing by arranging a crushing cylinder, a crushing roller, a crushing shell, a wheel disk, a crushing knife and a screen. After the material enters the crushing cylinder, it is crushed with the help of the crushing roller, and then enters the feed cylinder through the discharge hopper and the discharge pipe, and finally enters the crushing shell. The wheel disk and the crushing knife in the crushing shell rotate at a high speed, and quickly crush the material into small particles until it can pass through the screen and fall down. The material that cannot pass through the screen will continue to stay in the crushing shell and be cut by the crushing knife until it is qualified. This process is efficient and time-saving, and suitable materials can be obtained in one process. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0031] See also Figure 1-7 As shown, the utility model is a raw material crusher for wear-resistant packaging materials, including a crushing drum 1, a workbench 2, a workbench 3, a crushing shell 4 and a feeding drum 5. The lower portion of the crushing drum 1 is fixed through a chamber 204 inside the workbench 2. A crushing roller 105 is rotatably arranged in the crushing drum 1, and crushing teeth 104 distributed in an annular array are fixed on the inner wall of the crushing drum 1. Crushing teeth 2 106 distributed in an annular array are fixed on the outer peripheral surface of the lower middle portion of the crushing roller 105.

[0032] The crushing drum 1 and the crushing roller 105 inside it are used for primary crushing of materials. The crushing drum 1 is fixed in the chamber 1 204 inside the workbench 1 2. The bottom of the crushing drum 1 is an open structure. The crushing teeth 104 and the crushing teeth 2 106 do not contact each other during operation. When the raw materials pass between the inner wall of the crushing drum 1 and the outer wall of the crushing roller 105, they will inevitably contact a large number of crushing teeth 104 and crushing teeth 2 106. As a result, large pieces of material will be continuously crushed into small pieces.

[0033] The second workbench 3 is located on one side of the first workbench 2, and a through chamber 303 is provided in the second workbench 3. A crushing shell 4 is fixed in the second chamber 303, and a second motor 401 is fixed to the upper end of the crushing shell 4. The output shaft of the second motor 401 passes through the crushing shell 4 downward and extends into the inner cavity of the crushing shell 4. A wheel disc 402 is fixed therein, and crushing knives 403 distributed in a ring array are fixed on the outer periphery of the wheel disc 402;

[0034] The second chamber 303 in the second workbench 3 is fixed with the crushing shell 4, and the second motor 401 is installed on the upper end of the chamber 303. The second motor 401 drives the rotation of the wheel and the crushing knife 403 inside the crushing shell 4, so that the raw materials entering the crushing shell 4 are quickly crushed.

[0035] The upper end of the crushing shell 4 is fixed with a feed barrel 5, and a piston 502 is provided in the feed barrel 5 for upward and downward movement. The material introduced into the feed barrel 5 by the discharge pipe 203 is continuously squeezed downward by the up-and-down movement of the piston 502, so that the material enters the crushing shell 4 faster.

[0036] A screen 302 is fixed to the bottom of the workbench below the second chamber 303 ; the screen 302 is used to screen the material crushed in the crushing shell 4 , and the material with qualified particle size falls through the screen 302 , while the unqualified material continues to remain in the crushing shell 4 for crushing.

[0037] The four corners of the bottom of workbench 1 2 are fixed with support legs 1 201, and the four corners of the bottom of workbench 2 3 are fixed with support legs 2 301. Support legs 1 201 are higher than support legs 2 301, and workbench 1 2 is higher than workbench 2 3. The height difference design allows the material in the grinding cylinder 1 to smoothly enter the feeding cylinder 5.

[0038] An inverted U-shaped bracket 101 is fixed to the upper portion of the outer periphery of the pulverizing cylinder 1, and a motor 102 is fixed to the top of the bracket 101. The output shaft of the motor 102 passes downward through the bracket 101 and is fixed to a rotating shaft 103. The bottom end of the rotating shaft 103 is rotatably connected to a support bar 205 fixed inside the chamber 1 204.

[0039] The motor 102 is mounted on the grinding cylinder 1 through the bracket 101. The motor 102 drives the rotating shaft 103 to rotate. The bottom of the rotating shaft 103 and the support bar 205 rotate to help increase the stability of the rotating shaft 103.

[0040] A pulverizing roller 105 is fixed to the outer periphery of the portion of the rotating shaft 103 that extends into the pulverizing cylinder 1. The upper portion of the pulverizing roller 105 is a truncated cone-shaped structure, and the middle and lower portions of the pulverizing roller 105 are cylindrical structures. The pulverizing teeth 104 and the pulverizing teeth 106 do not contact each other. The pulverizing teeth 104 and the pulverizing teeth 106 are arranged in an alternating pattern when viewed from above, and are arranged in a high-low order when viewed from the front.

[0041] The rotation of the rotating shaft 103 drives the rotation of the crushing roller 105. After the crushing roller 105 rotates, the material entering between the outer wall of the crushing roller 105 and the inner wall of the crushing cylinder 1 will quickly contact the crushing teeth 104 and the crushing teeth 2 106, and the large pieces of material will be quickly crushed into small particles.

[0042] A hopper 202 is fixed to the bottom surface of the workbench 2 below the chamber 1 204, and a feeding pipe 203 is fixed through the bottom end of the hopper 202. The lower end of the feeding pipe 203 is connected to the side of the feeding barrel 5.

[0043] After being crushed in the crushing cylinder 1 , the material will enter the lower hopper 202 , and the lower hopper 202 will slide down through the discharge pipe 203 and be introduced into the barrel 5 .

[0044] A cylinder 501 is fixed to the upper end of the feed barrel 5, and a piston 502 at the telescopic end of the cylinder 501 extends downward through the feed barrel 5 and is fixedly connected to the upper end of the piston 502 in the feed barrel 5; the height of the piston 502 is higher than the diameter of the discharge pipe 203;

[0045] The cylinder 501 drives the piston 502 to perform reciprocating lifting and lowering, but the highest point of the piston 502 will never be lower than the highest point of the bottom end of the discharge pipe 203. During the lifting and lowering process of the piston 502, the material entering the feed barrel 5 from the discharge pipe 203 will be continuously pressed down quickly and squeezed into the crushing shell 4, so that it can be crushed quickly.

[0046] The specific working principle of the present invention is as follows: first, the crushing cylinder 1 is fixed in the chamber 1 204 in the workbench 1 2, the bottom of the crushing cylinder 1 is an open structure, and the motor 102 is installed on the crushing cylinder 1 through the bracket 101. The motor 102 drives the rotating shaft 103 to rotate. The rotation of the rotating shaft 103 drives the rotation of the crushing roller 105. After the crushing roller 105 rotates, the material is put into the crushing cylinder 1 from the upper end. The material entering between the outer wall of the crushing roller 105 and the inner wall of the crushing cylinder 1 will quickly contact the crushing teeth 104 and the crushing teeth 2 106. The large pieces of material will be quickly broken into small particles and finally enter the discharge hopper 202 and then guided through the discharge pipe 203. The raw materials are fed into the feeding barrel 5. At this time, the cylinder 501 drives the piston 502 to perform reciprocating lifting and lowering. During the lifting process of the piston 502, the material in the feeding tube 203 entering the feeding barrel 5 will be continuously pressed down quickly and squeezed into the crushing shell 4. At this time, the motor 2 401 drives the wheel to rotate and the crushing knife 403 to rotate inside the crushing shell 4, so that the raw materials entering the crushing shell 4 are quickly crushed. The wheel disc 402 and the crushing knife 403 in the crushing shell 4 rotate at high speed, and the material is quickly crushed into small particles until it can pass through the screen 302 and fall down. The material that cannot pass through the screen 302 will continue to stay in the crushing shell 4 and be cut by the crushing knife 403 until it is qualified.

[0047] The above are only preferred embodiments of the present invention and do not limit the present invention. Any modification to the technical solutions described in the aforementioned embodiments, any equivalent replacement of some of the technical features therein, and any modification, equivalent replacement, and improvement made are within the scope of protection of the present invention.
