After the glue-coated composite release paper is cut, the rubber band loses the pulling force applied by the equipment conveying and will rebound, so that the formed self-adhesive woven rubber band is in a bent state, resulting in poor quality of the self-adhesive woven rubber band. Summary of the invention

[0004] In order to improve the product quality of self-adhesive braided rubber bands, the present application provides a self-adhesive braided rubber band production device.

[0005] The self-adhesive woven rubber band production equipment provided in this application adopts the following technical solution: A self-adhesive woven rubber band production equipment comprises a frame, the frame comprises a base and a vertical frame, the vertical frame is sequentially provided with a combing mechanism, a rubber band conveying mechanism, a release paper conveying mechanism, a gluing mechanism, a compounding mechanism and a cutting mechanism, a force unloading mechanism is arranged between the rubber band conveying mechanism and the compounding mechanism, the force unloading mechanism comprises a force unloading frame and a force unloading pulley, the force unloading frame is installed on the vertical frame, the force unloading pulley is rotatably arranged on the force unloading frame, and the force unloading pulley is slidably arranged on the force unloading frame along the height direction of the vertical frame.

[0006] By adopting the above technical scheme, the main reason why the rubber band generates tension during the conveying process is that the rubber band has elasticity, and the rollers conveying the rubber band at the two places where the front end is unwinding and the rear end is compounded are powered, and the front end and the rear end of the rubber band are conveyed according to the rotation speed of their respective rollers. The setting of the unloading mechanism can form a section of the rubber band that naturally droops between the unwinding end and the compounding end, so that the rubber band is not in a tight state during the conveying process, thereby reducing the probability of the rubber band being pulled during compounding, reducing the probability of the self-adhesive braided rubber band after compounding being bent, and improving the product quality of the self-adhesive braided rubber band.

[0007] Optionally, detectors are provided at the top and bottom of the unloading frame corresponding to the unloading pulleys, and the detectors detect the distance from the unloading pulley to the top or bottom of the unloading frame.

[0008] By adopting the above technical solution, the detector can detect the position of the unloading pulley, thereby facilitating the control of the position of the unloading pulley by adjustment, reducing the probability of the unloading pulley losing its unloading function, and also reducing the probability of rubber bands accumulating at the unloading mechanism and affecting the normal operation of the equipment.

[0009] Optionally, the rubber band conveying mechanism includes a conveying roller and a conveying wheel, the conveying roller is rotatably arranged on the stand, the conveying wheel is arranged in contact with the conveying roller, and the conveying wheel is rotatably arranged on the stand.

[0010] By adopting the above technical solution, the conveying roller is driven by a motor to convey the rubber band, and the conveying wheel reduces the probability of the rubber band slipping by clamping.

[0011] Optionally, the rubber band conveying mechanism also includes an adjusting component, which includes an adjusting plate, an adjusting member and a mounting platform, the adjusting plate is mounted on the stand, the adjusting member is mounted on the adjusting plate, the mounting platform is mounted on the adjusting member, the conveying wheel is rotatably disposed on the mounting platform, and the adjusting member drives the mounting platform to slide in a direction toward and then away from the conveying roller.

[0012] By adopting the above technical solution, the height of the conveying wheel is adjusted by the adjusting assembly. When the rubber band does not need to be conveyed, the pressure on the rubber band is removed by driving the conveying wheel away from the conveying roller, so that the rubber band floats up and leaves the conveying roller, thereby stopping the conveying of the rubber band.

[0013] Optionally, a clamping mechanism is arranged between the rubber band conveying mechanism and the combing mechanism, and the clamping mechanism includes a clamping platform, a clamping plate, a clamping member and a clamping block. The clamping platform is fixed on the vertical frame, the clamping plate is fixed on the vertical frame above the clamping platform, the clamping member is installed on the clamping plate, and the clamping block is installed on the clamping member, and the clamping member drives the clamping block to slide toward or away from the clamping platform.

[0014] By adopting the above technical solution, the clamping mechanism can clamp the rubber band when the rubber band conveying mechanism stops conveying the rubber band, thereby reducing the probability of the rubber band rebounding.

[0015] Optionally, a dividing mechanism is provided on the vertical frame before and after the combing mechanism, and the dividing mechanism includes a dividing rod and a partition plate. There are two dividing rods, which are arranged in parallel on the vertical frame, and there are several partition plates, which are evenly arranged along the length direction of the dividing rods, and the dividing rods and the partition plates form several through holes.

[0016] By adopting the above technical solution, the rubber bands are separated by respectively passing a plurality of rubber bands through a plurality of passing holes, thereby reducing the probability of the rubber bands being entangled during transportation.

[0017] Optionally, the number of the unloading pulleys corresponds to the number of the through holes, the number of the conveying wheels and the clamping blocks corresponds to the unloading pulleys, the number of the adjusting members and the mounting platform corresponds to the conveying wheels, and the number of the clamping members corresponds to the clamping blocks.

[0018] By adopting the above technical solution, a plurality of conveying wheels and mounting platforms can respectively clamp and convey a plurality of rubber bands, thereby realizing the separate conveying of the rubber bands, that is, the conveying of a single rubber band can be adjusted when the unloading force of the rubber band is different due to its own roughness, and the probability of the rubber bands being entangled during the conveying process can also be reduced.

[0019] Optionally, a positioning plate is provided on the stand in front of the composite mechanism, and a plurality of guide grooves are provided on the positioning plate corresponding to the number of the through holes.

[0020] By adopting the above technical solution, the guide groove can reduce the probability of multiple rubber bands overlapping each other during compounding, thereby improving the compounding quality.

[0021] A force-unloading and conveying method for a self-adhesive woven rubber band production device comprises the following steps: S1: The rubber band is threaded so that the rubber band leaving the combing mechanism passes through the clamping table and the clamping block, the conveying roller and the conveying wheel, and the unloading pulley in sequence and then enters the compound mechanism; S2: conveying the rubber band to the unloading mechanism, driving the clamping block away from the clamping table, and driving the conveying wheel and the conveying roller to clamp the rubber band, and conveying the rubber band to the unloading mechanism through the rotation of the conveying roller; S3: Rubber unloading conveying. When the unloading pulley slides close to the bottom of the unloading frame due to the rubber conveying, the clamping block is driven close to the clamping table to clamp the rubber, and the conveying wheel is driven away from the conveying roller to stop conveying the rubber to the unloading mechanism. At this time, the rubber is driven into the compounding mechanism by the power of the compounding mechanism for compounding. The speed of rubber unloading conveying is lower than the speed of conveying the rubber to the unloading mechanism. When the unloading pulley approaches the top of the unloading frame, the rubber is conveyed to the unloading mechanism again.

[0022] By adopting the above technical scheme, a certain amount of rubber is reserved at the unloading mechanism through the rubber conveying mechanism cooperating with the unloading mechanism, the rubber is straightened by the unloading pulley's own gravity and is not in a pulled state, and then the rubber is conveyed to the compounding mechanism for compounding. The compounding speed of the compounding mechanism is lower than the conveying speed of the conveying roller. After a period of compounding, the unloading pulley will gradually approach the bottom of the unloading frame. At this time, the conveying wheel is driven away from the conveying roller to stop the rubber from being conveyed to the unloading mechanism. After the unloading pulley is lifted away from the bottom of the unloading frame by the compounding mechanism, the conveying wheel is pressed on the rubber to continue conveying the rubber. The setting of the unloading mechanism ensures that there is always a section of the rubber in a state where it is not pulled, thereby reducing the bending and twisting of the self-adhesive braided rubber after compounding, and improving the quality of the self-adhesive braided rubber.

[0023] In summary, the present application includes at least one of the following beneficial technical effects: The main reason why the elastic band generates tension during the conveying process is that the elastic band is elastic, and the rollers conveying the elastic band at the front unwinding end and the rear compounding end are powered, and the front and rear ends of the elastic band are conveyed according to the rotation speed of their respective rollers. The setting of the unloading mechanism can form a section of the elastic band that naturally sags between the unwinding end and the compounding end, so that the elastic band is not in a tight state during the conveying process, thereby reducing the probability of the elastic band being pulled during compounding, and reducing the probability of the self-adhesive braided elastic band being bent after compounding, thereby improving the product quality of the self-adhesive braided elastic band; The detector can detect the position of the unloading pulley so as to facilitate the control of the position of the unloading pulley by adjustment, reduce the probability of the unloading pulley losing its unloading function, and also reduce the probability of the rubber band accumulating at the unloading mechanism and affecting the normal operation of the equipment; The height of the conveying wheel is adjusted by the adjusting assembly. When the rubber band does not need to be conveyed, the conveying wheel is driven away from the conveying roller to relieve the pressure on the rubber band, so that the rubber band floats up and leaves the conveying roller, thereby stopping the conveying of the rubber band; The clamping mechanism can clamp the rubber band when the rubber band conveying mechanism stops conveying the rubber band, thereby reducing the probability of the rubber band rebounding; The rubber bands are separated by respectively passing the plurality of rubber bands through the plurality of passing holes, thereby reducing the probability of the rubber bands being entangled during transportation; Through the rubber conveying mechanism and the unloading mechanism, a certain amount of rubber is reserved at the unloading mechanism, and the rubber is straightened by the unloading pulley's own weight and is not in a pulled state, and then the rubber is conveyed to the compounding mechanism for compounding. The compounding speed of the compounding mechanism is lower than the conveying speed of the conveying roller. After a period of compounding, the unloading pulley will gradually approach the bottom of the unloading frame. At this time, the conveying wheel is driven away from the conveying roller to stop the rubber from being conveyed to the unloading mechanism. After the unloading pulley is lifted away from the bottom of the unloading frame by the compounding mechanism, the conveying wheel is pressed on the rubber to continue conveying the rubber. The setting of the unloading mechanism ensures that there is always a section of the rubber in a state of not being pulled, thereby reducing the bending state of the self-adhesive braided rubber after compounding and improving the quality of the self-adhesive braided rubber.

DETAILED DESCRIPTION

[0033] The following is combined with Figure 1-8 This application is described in further detail.

In addition, in this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", and "connected" appear, they should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection, a limited connection such as an interference fit, a transition fit, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium; therefore, for ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0035] The present application embodiment discloses a self-adhesive woven elastic production device, referring to Figure 1 , Figure 2 and Figure 3, including a frame 1, the frame 1 includes a base 101 horizontally arranged on the ground and a stand 102 vertically fixed to the base 101 perpendicular to the base 101, the stand 102 is sequentially provided with a combing mechanism 2, an elastic conveying mechanism 3, a release paper conveying mechanism 4, a gluing mechanism 5, a compound mechanism 6 and a cutting mechanism 7, a force unloading mechanism 8 is arranged between the elastic conveying mechanism 3 and the compound mechanism 6, the force unloading mechanism 8 includes a force unloading frame 81 installed on the stand 102 and a plurality of force unloading pulleys 82 rotatably arranged on the force unloading frame 81, in this embodiment, four force unloading pulleys 82 are arranged, each of which is used for unloading a rubber band, and the force unloading pulley 82 is slidably arranged on the force unloading frame 81 along the height direction of the stand 102, and the body weight of the force unloading pulley 82 is less than the minimum pulling force of the rubber band. For example, in this embodiment, the rubber band will be pulled longer by a pulling force of 40N, then the force unloading pulley 82 The weight of the body needs to be less than 40N. At the same time, the area of ​​the unloading frame 81 used for the unloading pulley 82 to slide needs to be smooth and frictionless. In this embodiment, the unloading pulley 82 has its own weight of 25N. The surface of the unloading frame 81 is prone to become rough due to long-term use and generate friction. The error value is reserved. The rubber band passes through the unloading pulley 82. The main reason for the tension of the rubber band during the transportation process is that the rubber band has elasticity, and the rollers conveying the rubber band at the two places where the front end is unrolled and the rear end is compounded are powered, and the front and rear ends of the rubber band are conveyed according to the rotation speed of their respective rollers. The setting of the unloading mechanism can form a section of the rubber band that naturally droops between the unwinding end and the compounding end, so that the rubber band is not in a tight state during the transportation process, thereby reducing the probability of the rubber band being pulled during compounding, reducing the probability of the self-adhesive braided rubber band being bent after compounding, and improving the product quality of the self-adhesive braided rubber band.

[0036] Reference Figure 1 , Figure 2 and Figure 3 , the unloading pulley 82 at the top and bottom of the unloading frame 81 is provided with a detector 9, and the detector 9 detects the distance from the unloading pulley 82 to the top or bottom of the unloading frame 81. The detector 9 can use a travel switch or a distance detection sensor. When the travel switch is used, the installation position of the travel switch needs to be adjusted according to the actual distance. When the distance sensor is used, the value of the distance sensor trigger needs to be preset. In this embodiment, the distance sensor is used, and the unloading pulley 82 is lowered to the bottom of the unloading frame 81 and then the rubber band is transported. The rubber band will accumulate at the unloading mechanism 8, and the rubber band is easily entangled in other structures of the equipment, causing the equipment to be stuck and damaged. When the unloading pulley 82 is stretched to the top of the unloading frame 81, the unloading pulley 82 will lose its unloading function. The detector 9 can detect the position of the unloading pulley 82, so as to facilitate the position of the unloading pulley 82 by adjusting and controlling, thereby reducing the probability of the unloading pulley 82 losing its unloading function, and also reducing the probability of the rubber band accumulating at the unloading mechanism 8 to affect the normal operation of the equipment.

In this embodiment, four conveying wheels 32 are arranged corresponding to the number of unloading pulleys 82. The conveying wheel 32 is rotatably arranged on the stand 102. The conveying roller 31 is driven by a motor to convey the rubber. The conveying wheel 32 reduces the probability of the rubber slipping by clamping. The rubber conveying mechanism 3 also includes an adjusting component 33. The adjusting component 33 includes an adjusting plate 331 installed on the stand 102, a plurality of adjusting members 332 installed on the adjusting plate 331, and a mounting platform 333 installed on the adjusting member 332.

The adjustment members 332 drive the mounting platforms 333 to slide in a direction close to and then away from the conveying roller 31. The height of the conveying wheel 32 is adjusted by the adjustment assembly 33. When the rubber band does not need to be conveyed, the pressure on the rubber band is removed by driving the conveying wheel 32 away from the conveying roller 31, so that the rubber band floats up and separates from the conveying roller 31, thereby stopping the conveying of the rubber band. The multiple adjustment members 332 respectively adjust the multiple conveying wheels 32. On the one hand, the probability of the rubber band slipping and mixing together during the conveying process can be avoided. On the other hand, when the positions of the unloading pulleys 82 are not synchronized, the conveying wheels 32 can be driven by the adjustment members 332 to adjust the lifting and lowering of individual unloading pulleys 82, so that all the unloading pulleys 82 return to a synchronized state.

The gluing head is connected to the glue source, and glue is applied to the side where the release paper and the rubber band are attached to each other. The glue is compounded to the rubber band through the release paper, and the release paper is subsequently torn off to make the rubber band have adhesion.

The upper composite belt 63 is driven by a cylinder to rise and fall on the stand 102. The composite guide roller 61 guides the rubber band to send the rubber band between the upper composite belt 63 and the lower composite belt 62, and then the upper composite belt 63 and the lower composite belt 62 are continuously pressed to be composited. The sliding setting of the upper composite belt 63 can The compounding pressure is adjusted to reduce the probability of the rubber band being pulled during compounding. At the same time, since the instantaneous pressure during compounding cannot be too large, it is necessary to set the upper compounding belt 63 and the lower compounding belt 62 to apply a small pressure to the rubber band and the release paper for a longer time, thereby improving the compounding effect; a positioning plate 13 is arranged on the stand 102 in front of the compounding mechanism 6, and a plurality of guide grooves 14 are opened on the positioning plate 13 corresponding to the number of the through holes 12.

The clamping component 1003 drives the clamping block 1004 to abut against the clamping platform 1001 to clamp the rubber band, thereby reducing the probability of the rubber band rebounding when the rubber band is not transported. When the clamping component 1003 drives the clamping block 1004 away from the clamping platform 1001, the rubber band can be transported between the clamping platform 1001 and the clamping block 1004.

[0044] Reference Figure 1 , Figure 2 and Figure 8 A dividing mechanism 11 is provided on the frame 102 before and after the combing mechanism 2.

The rubber bands are separated by respectively penetrating the plurality of penetration holes 12, thereby reducing the probability of the rubber bands being entangled during transportation.

[0045] A force-unloading and conveying method for a self-adhesive woven rubber band production device comprises the following steps: S1: rubber band threading, so that the rubber band leaving the combing mechanism 2 passes through between the clamping table 1001 and the clamping block 1004, between the conveying roller 31 and the conveying wheel 32, and the force-unloading pulley 82 in sequence and then enters the composite mechanism 6; S2: conveying the rubber band to the force-unloading mechanism 8, driving the clamping block 1004 away from the clamping table 1001, and driving the conveying wheel 32 and the conveying roller 31 to clamp the rubber band, and conveying the rubber band to the force-unloading mechanism 8 by rotating the conveying roller 31; S3: rubber band force-unloading conveying, when the rubber band conveying causes the force-unloading pulley 82 to slide to the bottom of the force-unloading frame 81, the clamping block 1004 is driven to approach the clamping table 1001 to clamp the rubber band, and at the same time When the unloading pulley 82 is close to the top of the unloading frame 81, the rubber is transported to the unloading mechanism 8 again. Since the speed of unloading the rubber is lower than the speed of unloading the rubber, when the conveying wheel 32 presses the rubber onto the conveying roller 31, the unloading pulley 82 will gradually slide toward the bottom of the unloading frame 81. When the unloading pulley 82 is close to the top of the unloading frame 81 again, the conveying wheel 32 is moved away from the conveying roller 31 to stop the rubber transport to the unloading mechanism 8.

[0046] The implementation principle of the embodiment of the present application is as follows: four rubber bands are passed through the dividing mechanism 11 in front of the combing mechanism 2, and then the rubber bands pass through the combing mechanism 2 and then through the dividing mechanism 11 behind the combing mechanism 2, and after passing through the dividing mechanism 11, the rubber bands pass through the clamping mechanism 10, the rubber band conveying mechanism 3, and the force unloading mechanism 8 in sequence and then enter the compounding mechanism 6, and at the same time, the release paper roll is unrolled and conveyed at the release paper conveying mechanism 4, and the release paper is coated with glue by the gluing mechanism 5 and then enters the compounding mechanism 6, and after the rubber bands and the release paper are compounded by the compounding mechanism 6, they are cut by the cutting mechanism 7 to complete the production and processing of the self-adhesive woven rubber bands.
