Description

Technical Field

[0001] The invention relates to the technical field of natural rubber extrusion molding-weighing, in particular to a molding-weighing integrated machine for rubber and a molding and weighing method thereof. Background Art

[0002] After the natural rubber is collected, it needs to be broken up and then some auxiliary materials are added for mixing. After the mixing is completed, the rubber materials need to be squeezed into blocks and then transported (on the one hand, it is convenient for transportation, and on the other hand, it avoids the broken rubber materials from contacting with air and causing certain qualitative changes).

[0003] In the current natural rubber industry (a small number of Chinese companies, most of which are concentrated in Southeast Asia), the equipment used is increasingly unable to meet the needs of mass production. In the current natural rubber extrusion and weighing methods, the extrusion mechanism and the weighing mechanism are separated. The extrusion mechanism is easy to stick to the inner wall of the extrusion mechanism when pressing the natural rubber material, making it difficult to clean. In addition, the means of extrusion and weighing are also very simple: when extruding, pour some rubber material, and then extrude it into a separate rubber block; weigh the extruded rubber block; then extrude the next rubber block and weigh it again; in this way, extrude multiple rubber blocks, weigh multiple rubber blocks, calculate the total weight of the weighed multiple rubber blocks, and then compare it with the weight required by the customer. If it does not meet the standard, cut a part of the rubber material to make up for it.

[0004] The existing problems are: 1. When the total weight of the rubber is insufficient, the additional rubber material is manually adhered to the rubber block. During the repeated handling process, these adhered rubber materials are very easy to fall off (rubber materials are similar to dough), resulting in the final customer receiving rubber materials that are less than the weight of the scale; 2. During the extrusion molding process, the weight difference between each rubber block is large. When a customer needs a rubber block of a certain total weight, it is necessary to select multiple rubber blocks from the warehouse, and it is difficult to select multiple rubber blocks of appropriate weight to piece together the rubber blocks required by the customer; 3. Whether in the extrusion or weighing environment, a large amount of manual participation is required, the degree of automation is low, and it is difficult to meet mass production; when the customer needs it, more people are also required to participate in the selection of materials for delivery, and it may result in the customer receiving rubber materials that are less than the weight of the scale. Summary of the invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a rubber molding-weighing integrated machine and a molding and weighing method thereof, so as to solve the calculation problem that the existing rubber material is easy to fall off during transportation, and also solve the technical problem of low degree of automation of extrusion and weighing, and also solve the problem that it is difficult to select rubber blocks when a certain total weight of rubber material is required.

[0006] The purpose of the present invention is achieved through the following technical solutions:

[0007] In a first aspect, a molding-weighing integrated machine for rubber is disclosed, comprising an extrusion molding part I, a cutting part II, and a weight adjustment part III;

[0008] The extrusion molding part I has an extrusion inner cavity in the left and right directions; a feed port is provided at the front and rear walls of the right end of the extrusion inner cavity, and a discharge port is provided at the left end of the extrusion inner cavity; a piston plate is also adaptively provided in the extrusion inner cavity;

[0009] The cutting part II is arranged at the discharge port at the left end of the extrusion forming part I;

[0010] The weight adjustment part III is arranged on the left side of the cutting part II; the weight adjustment part III includes a long conveying mechanism and a length measuring device, and a length measuring device is arranged on the outer side of the right end of the long conveying mechanism; a weighing machine is arranged on the left end of the length conveying mechanism; the length measuring device, the weighing machine, and the cutting part II are all electrically connected to the control panel;

[0011] The rubber material is put into the extrusion cavity from the feed port, and is squeezed under the action of the piston plate, and then extruded from the discharge port; the extruded rubber moves to the left under the drive of the long conveying mechanism, and the length measuring device can measure the length of the extruded rubber, and the cutting part II can cut the extruded rubber to form a rectangular rubber block; when the rectangular rubber block is weighed, if it is overweight / underweight, the length of the next time is measured by the length measuring device, so that more material can be cut / supplemented in the next cutting, so that the sum of the weights of multiple rubber blocks is the set value.

[0012] As a preferred technical solution of the present application, the extrusion molding section I includes a first compartment section, a second compartment section, and a third compartment section connected sequentially from right to left; the first compartment section is rectangular, and has a feed port at the front and rear walls of the right end, and a pushing cylinder is arranged at the right end; the pushing cylinder is connected to the piston plate; the second compartment section is rectangular, and a plurality of nozzles are arranged on its wall; the nozzles can spray out anti-sticking oil. After the rubber material is placed in the first compartment section, it can be pushed into the second compartment section under the action of the piston plate, and the rubber material can be sprayed with anti-sticking oil in the second compartment section; the rubber material is pushed from the right end to the left end in the second compartment section by the piston plate, and the rubber is pressed against the knife plate of the cutting section II to complete the extrusion, forming a material with a rectangular cross section.

[0013] As a preferred technical solution of the present application, the extrusion molding part I also includes a third compartment section; the right end of the third compartment section is a large rectangular opening, the left end is a small rectangular opening, and the small rectangular opening on the left end is a discharge port; the third compartment section is provided at the left end of the second compartment section; when the rubber moves from right to left in the third compartment section, it is squeezed on the cross section.

[0014] Furthermore, each cabin section has flanges at both left and right ends, and the flanges are connected by bolts to form a detachable structure.

[0015] As a preferred technical solution of the present application, in the weight adjustment part III: the long conveying mechanism includes a plurality of rollers arranged at intervals, and a conveying belt is arranged on the rollers.

[0016] As a preferred technical solution of the present application, in the weight adjustment part III: the length measuring device includes a long strip plate, a lead screw driven by a servo motor is arranged on the long strip plate, and a laser sensor is mounted on the lead screw; the laser sensor and the long strip plate are also slidably matched through a slide groove. The servo motor controls the position of the laser sensor on the long strip plate by controlling the number of turns of the lead screw, thereby controlling the length position between the laser sensor and the cutting part II.

[0017] As a preferred technical solution of the present application, in the weight adjustment part III: the weighing machine includes a material frame, and an electronic weighing scale is arranged below the material frame.

[0018] As the preferred technical solution of the present application, the cutting part II comprises a gantry; vertical grooves are provided on the left and right walls of the gantry, and a knife plate capable of moving up and down is installed in the vertical grooves; a cutting cylinder is provided on the crossbeam of the gantry.

[0019] Furthermore, a detachable carbide blade is provided at the bottom of the blade plate.

[0020] In a second aspect, a molding and weighing method for a rubber molding-weighing integrated machine is also disclosed, comprising the following steps:

[0021] S1. When the rubber material is squeezed out of the discharge port like a toothpaste base, the cross section of the extruded rubber material is rectangular, and the rectangular size of the cross section is consistent with the size of the discharge port;

[0022] S2. The extruded rubber is gradually displaced to the left under the drive of the long conveying mechanism, so that the displacement speed of the long conveying mechanism is consistent with the speed at which the rubber material is extruded;

[0023] S3, the servo motor drives the lead screw to rotate, thereby driving the laser sensor to move, and preliminarily adjusting the distance between the laser sensor and the cutting part II in the left and right directions - the length is set manually, when the laser sensor senses the left end of the extruded rubber, the cutting cylinder in the cutting part II drives the blade to move, and the extruded rubber material is cut off, and the cut rubber material becomes a long rectangular rubber block;

[0024] S4, then the extrusion molding part I stops extruding the rubber material first, and the long conveying mechanism drives the rubber block to move to the left, and the rubber block falls into the material frame in the weighing machine, and then the weight of the rubber block is weighed by the electronic weighing scale;

[0025] S5. The electronic weighing scale transmits the weighed weight to the PLC control panel. The weight of each rubber block is preset with a certain calibration value in the PLC. The PLC control panel obtains the actual weight of the cut rubber block and compares it with the calibration value - and calculates the weight difference. In addition, the PLC control panel can also calculate the density of the rubber block based on the actual weight, the size of the discharge port, and the length of the rubber block;

[0026] S6. According to the weight difference, density and the size of the discharge port, the length of the next rubber block to be cut off is calculated to make up the difference. If the actual weight is greater than the calibration value, the next cutting length is shortened. If the actual weight is less than the calibration value, the next cutting length is increased. Then the PLC controls the servo motor in the length measuring device to move - adjust the position of the laser sensor.

[0027] S7, then the extrusion molding part I continues to extrude, and when the rubber material is extruded to a corresponding length, it is cut off again to form a second rubber block;

[0028] S8, the third rubber block, the fourth rubber block and the subsequent rubber blocks are formed in this way. Since the weights of the adjacent rubber blocks to be cut are related, each time the weight of a rubber block deviates, it can be adjusted by the weight of the next rubber block;

[0029] S9. After cutting a plurality of rubber blocks in this way, the PLC also accumulates the weight of these rubber blocks and compares it with the total rubber weight required in the end. When there is an error, the weight is adjusted at the last rubber block.

[0030] The present invention has the following advantages:

[0031] (1) High degree of automation, improved work efficiency, suitable for mass production;

[0032] In this solution, the rubber material can be automatically put into the extrusion cavity through some feeding equipment, and the extrusion-length measurement-cutting-weighing and the like can be automatically performed, thereby improving the production efficiency;

[0033] (2) The total weight of all the cut rubber blocks can be controlled more accurately, which is convenient for subsequent weight selection and prevents material from falling off during transportation;

[0034] In this scheme, when a certain rubber block is cut off, it will be compared with the standard weight. When the rubber block does not meet the standard weight, the weight will be supplemented (increased / decreased) when the next rubber block is cut;

[0035] In this way, when customers need a certain total weight of rubber material, they can quickly find rubber blocks that can be combined to form the total weight (for example, assuming that the standard weight of each rubber block is 0.5 tons, the weight of the first rubber block is 0.4 tons, the weight of the second rubber block is 0.6 tons - the extra 0.1 tons is used to make up the weight of the first rubber block, the weight of the third rubber block is 0.55 tons, and the weight of the fourth rubber block is 0.45 tons - the third rubber block is also used to make up the weight; when the customer needs 2 tons of rubber material, these 4 blocks can be selected; similarly, when the weight is 10 tons, 100 tons, etc., through this method of weight-complementing adjacent rubber blocks, the corresponding rubber blocks can be quickly found in the factory warehouse for combination);

[0036] In addition, since the latter rubber block is used to make up for the former rubber block, when customers need a certain total weight of rubber materials, they can always find suitable rubber blocks to combine easily and quickly, without having to manually cut off a portion of the material and stick it to the rubber block, and without having to worry about the subsequent adhesion of the rubber material falling off, so that customers can receive materials of sufficient weight;

[0037] (3) The nozzle arranged at the second compartment allows the anti-sticking oil sprayed by the nozzle to be located on the surface of the rubber material, which can prevent the material from adhering to the inner wall of the compartment when the third compartment is extruded; in addition, the extrusion cavity formed can be penetrated from left to right, especially the front and rear walls of the right end of the extrusion cavity are provided with a feed inlet, if a small amount of material adheres to the inner wall, it can also be cleaned in time; in addition, the compartments are detachable, and when a large amount of material is indeed adhered, it can also be convenient to disassemble and clean it in time.

[0047] The present invention is further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0048] It should be noted that the directions or positional relationships indicated by "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the inventive product is usually placed when in use, or are the directions or positional relationships commonly understood by those skilled in the art. Such terms are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0049] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0050] First, as Figure 1 to Figure 4 As shown, this specific embodiment discloses a molding-weighing integrated machine for rubber, including an extrusion molding part I, a cutting part II, and a weight adjustment part III;

[0051] The extrusion molding part I has an extrusion cavity in the left and right directions, a feed port 101 is provided at the front and rear walls of the right end of the extrusion cavity 0, a discharge port 102 is provided at the left end of the extrusion cavity, and a piston plate 103 is also adaptively provided in the extrusion cavity;

[0052] Wherein, the cutting part II is arranged at the discharge port 102 at the left end of the extrusion forming part I;

[0053] The weight adjustment part III is arranged on the left side of the cutting part II; the weight adjustment part III includes a long conveying mechanism 50 and a length measuring device 60, and the length measuring device 60 is arranged outside the right end of the long conveying mechanism 50; a weighing machine is arranged at the left end of the length conveying mechanism 50; the length measuring device 60, the weighing machine, and the cutting part II are all electrically connected to the control panel;

[0054] The rubber material is put into the extrusion cavity from the feed port 101, and is squeezed under the action of the piston plate 103, and then is extruded from the discharge port 102; the extruded rubber moves to the left under the drive of the long conveying mechanism 50, and the length measuring device 60 can measure the length of the extruded rubber, and the cutting part II can cut the extruded rubber to form a rectangular rubber block; when the rectangular rubber block is weighed, if it is overweight / underweight, the length of the next time is measured by the length measuring device 60, so that more material can be cut / supplemented in the next cutting, so that the sum of the weights of multiple rubber blocks is the set value.

[0055] The extrusion molding part I is further explained below.

[0056] See also Figure 2 The extrusion molding part I includes a first compartment section 20 and a second compartment section 30 connected sequentially from right to left. The first compartment section 20 and the second compartment section 30 are both penetrated from left to right, and the left and right ends of each compartment section have flanges, and the adjacent flanges are connected by bolts to form a detachable structure; the cutting part II is fixed to the flange at the left end of the second compartment section 30. The first compartment section 20 and the second compartment section 30 are supported by brackets.

[0057] Optionally, an auxiliary slide groove in the left and right directions can be opened on the bracket, and the lower part of each cabin section is adapted to the auxiliary slide groove and connected via a locking screw; when it is necessary to open each cabin section, the bolts are removed and then the locking screws are removed, so that the auxiliary slide groove can be slid in the left and right directions, thereby facilitating the cleaning of materials on the inner walls of each cabin section.

[0058] The first cabin section 20 is rectangular, and a feed port 101 is provided on its side, and a feed bin is welded at the feed port 101; a push cylinder 104 is provided at the right end of the first cabin section 20, and a piston plate 103 is fixed at the end of the push cylinder 104. The piston plate 103 extends into the first cabin section 20.

[0059] The second compartment section 20 is also rectangular, and its cross-sectional size is adapted to that of the first compartment section 20. Multiple nozzles are arranged on the upper and lower walls and the front and rear walls of the second compartment section 20. The nozzles are connected to the tank body with anti-sticking oil through a pipeline, and a pump is arranged on the pipeline. When the pump is working, the anti-sticking oil is sprayed out from the nozzles, and the anti-sticking oil is sprayed on the surface of the rubber material.

[0060] During operation: the rubber material is put into the first compartment 20 through the feed port 101, and then pushed into the second compartment 30 under the action of the piston plate 103, and then the nozzle sprays anti-sticking oil; the piston plate 103 continues to move, so that the left end of the rubber material rests on the knife plate of the cutting part II (the knife plate is in a falling state at this time, and can close the discharge port 102), so as the piston plate 103 continues to move, the rubber material is gradually squeezed; when the knife plate of the cutting part II is lifted (the knife plate rises to open the discharge port 102), if the rubber material is continued to be squeezed through the piston plate 103, the rubber material will eventually be squeezed out from the discharge port 102, just like squeezing toothpaste, except that the cross-section of the squeezed rubber material is rectangular.

[0061] Of course, for the extrusion molding part I, another design can be adopted, that is, on the basis of the above extrusion molding part I, a third compartment section is added. The right end of the third compartment section 30 is a large rectangular opening, and the right end is the same size as the left end of the second compartment section 20; the left end of the third compartment section 30 is a small rectangular opening, which is the discharge port 102. In the third compartment section, the structure of large right and small left can better complete the extrusion.

[0062] The cutting part II is further explained below.

[0063] See also Figure 3 The cutting part II includes a gantry 80, a cutting cylinder is fixed on the crossbeam of the gantry 80, a knife plate 801 is arranged below the crossbeam, and the knife plate 801 is connected to the output end of the cutting cylinder; a vertical groove is opened between the opposite walls of the side frame of the gantry 80, and the side edge of the knife plate 801 is adapted to the vertical groove. A detachable carbide blade is arranged at the lower edge of the knife plate 801.

[0064] During operation, the cutting cylinder drives the blade 801 to move up and down, and the rubber material extruded at the outlet 101 can be cut into segments, so that the cut rubber material becomes a rubber block. Since the blade is very easy to wear when cutting rubber material, when wear occurs, the carbide blade is promptly removed and replaced with a new blade.

[0065] The weight adjustment part III is further explained below.

[0066] See also Figure 4 For the long conveying mechanism 50 in the weight adjustment part III, a plurality of rollers are arranged at intervals on the long frame, and a conveyor belt is arranged on the rollers.

[0067] In addition, the length measuring device 60 in the weight adjusting part III includes a long strip plate 61, on which a lead screw 63 driven by a servo motor 62 is arranged, and a laser sensor 64 is mounted on the lead screw 63 through threaded adaptation, and the bottom of the laser sensor 64 is slidably matched with the slide grooves opened on the upper surface of the long strip plate 61 through the protrusion. When working, the servo motor 62 controls the position of the laser sensor 64 on the long strip plate 61 by controlling the number of rotations of the lead screw 63, thereby controlling the length position between the laser sensor 64 and the cutting part II.

[0068] Furthermore, the weighing machine in the weight adjustment unit III includes a material frame, and an electronic weighing scale is provided below the material frame.

[0069] In addition, the electronic weighing scale in the weighing machine, the cutting cylinder in the cutting part II, the servo motor in the length measuring device 60, and the laser sensor in the length measuring device 60 are all connected to the PLC control panel.

[0070] In a second aspect, this specific embodiment discloses a molding and weighing method for a rubber molding-weighing integrated machine, which is implemented based on the above-mentioned molding-weighing integrated machine and includes the following steps:

[0071] S1. When the rubber material is squeezed out of the discharge port 102 like a toothpaste base, the cross section of the rubber material being squeezed out is rectangular, and the rectangular size of the cross section is consistent with the size of the discharge port 102;

[0072] S2. The extruded rubber is gradually displaced to the left under the drive of the long conveying mechanism 50, so that the displacement speed of the long conveying mechanism 50 is consistent with the speed at which the rubber material is extruded;

[0073] S3, the servo motor drives the lead screw to rotate, thereby driving the laser sensor to move, and preliminarily adjusting the distance between the laser sensor and the cutting part II in the left and right directions - the length is set manually, when the laser sensor senses the left end of the extruded rubber, the cutting cylinder in the cutting part II drives the blade 801 to move, and the extruded rubber material is cut off, and the cut rubber material becomes a long rectangular rubber block;

[0074] S4, then the extrusion molding part I stops extruding the rubber material, and the long conveying mechanism 50 drives the rubber block to move to the left, and the rubber block falls into the material frame in the weighing machine, and then the weight of the rubber block is weighed by the electronic weighing scale;

[0075] S5. The electronic weighing scale transmits the weighed weight to the PLC control panel. The weight of each rubber block is preset with a certain calibration value in the PLC. The PLC control panel obtains the actual weight of the cut rubber block and compares it with the calibration value, and calculates the weight difference. In addition, the PLC control panel can also calculate the density of the rubber block according to the actual weight, the size of the discharge port 102, and the length of the rubber block.

[0076] S6. According to the weight difference, density, and the size of the discharge port 102, the length of the next rubber block to be cut off is calculated to make up the difference. If the actual weight is greater than the calibration value, the next cutting length is shortened. If the actual weight is less than the calibration value, the next cutting length is increased. Then the PLC controls the servo motor in the length measuring device 60 to move - adjust the position of the laser sensor.

[0077] S7, then the extrusion molding part I continues to extrude, and when the rubber material is extruded to a corresponding length, it is cut off again to form a second rubber block;

[0078] S8, the third rubber block, the fourth rubber block and the subsequent rubber blocks are formed in this way. Since the weights of the adjacent rubber blocks to be cut are related, each time the weight of a rubber block deviates, it can be adjusted by the weight of the next rubber block;

[0079] S9. After cutting a plurality of rubber blocks in this way, the PLC also accumulates the weight of these rubber blocks and compares it with the total rubber weight required in the end. When there is an error, the weight is adjusted at the last rubber block.

[0080] The above embodiments only express preferred implementation modes, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.

When the rubber material is squeezed out of the discharge port (102) like a toothpaste base, the cross section of the rubber material being squeezed out is rectangular, and the size of the rectangle of the cross section is consistent with the size of the discharge port (102); S2, the extruded rubber is gradually displaced to the left under the drive of the long conveying mechanism (50), so that the displacement speed of the long conveying mechanism (50) is consistent with the speed at which the rubber material is extruded; S3, the servo motor drives the lead screw to rotate, thereby driving the laser sensor to move, and preliminarily adjusting the distance between the laser sensor and the cutting part II in the left and right directions - the length is set manually, when the laser sensor senses the left end of the extruded rubber, the cutting cylinder in the cutting part II drives the blade (801) to move, and the extruded rubber material is cut off, and the cut rubber material becomes a long rectangular rubber block; S4, then the extrusion molding part I stops extruding the rubber material, and the long conveying mechanism (50) drives the rubber block to move to the left, and the rubber block falls into the material frame in the weighing machine, and then the weight of the rubber block is weighed by an electronic weighing scale; S5, the electronic weighing scale transmits the weighed weight to the PLC control panel. The weight of each rubber block is preset with a certain calibration value in the PLC. The PLC control panel obtains the actual weight of the cut rubber block and compares it with the calibration value, and calculates the weight difference. In addition, the PLC control panel can also calculate the density of the rubber block according to the actual weight, the size of the discharge port (102), and the length of the rubber block; S6, based on the weight difference, density, and size of the discharge port (102), the length of the next rubber block to be cut off in order to make up the difference is calculated. If the actual weight is greater than the calibration value, the next cutting length is shortened. If the actual weight is less than the calibration value, the next cutting length is increased. Then the PLC controls the servo motor in the length measuring device 60 to move - adjust the position of the laser sensor. S7, then the extrusion molding part I continues to extrude, and when the rubber material is extruded to a corresponding length, it is cut off again to form a second rubber block; S8, the third rubber block, the fourth rubber block and the subsequent rubber blocks are formed in this way. Since the weights of the adjacent rubber blocks to be cut are related, each time the weight of a rubber block deviates, it can be adjusted by the weight of the next rubber block; S9. After cutting a plurality of rubber blocks in this way, the PLC also accumulates the weight of these rubber blocks and compares it with the total rubber weight required in the end. When there is an error, the weight is adjusted at the last rubber block.
