Description

Technical Field

[0001] The utility model relates to the technical field of pre-shrinking machines, in particular to a rubber blanket water squeezing and treatment device for a pre-shrinking machine. Background Technique

[0002] A pre-shrinking machine refers to a device that, under suitable wet and hot conditions, utilizes the expansion and contraction deformation of a rubber blanket to increase the weft density and radial fabric shrinkage to a certain extent, so that the fabric has a loose structure. When the fibers are wetted, swollen and dissolved, it will no longer cause radial length shortening, and the finished product shrinkage rate is reduced. During the pre-shrinking process, the spray water cools the rubber blanket, which will cause the surface of the rubber blanket to be water-bearing. To avoid problems such as water spots and water blisters on the fabric surface due to encountering water vapor, it is necessary to control the water content on the surface of the rubber blanket.

[0003] During the operation of the pre-shrinking machine, in order to prevent the rubber blanket from overheating, it is necessary to cool the rubber blanket through internal and external spray water. The surface of the rubber blanket is rough, and water-bearing phenomenon will occur. If the water squeezing is not clear, water spots and water blisters will be formed on the fabric. Therefore, it is necessary to carry out the backwashing process, which affects the delivery date and increases the cost.

[0004] After retrieval, a rubber blanket pre-shrinking machine with the application number 201921858581.7 has a water scraping mechanism including a core shaft, a sleeve rotatably sleeved on the core shaft, a water scraping plate fixedly connected to the sleeve, and a torsion spring connected between the core shaft and the sleeve; the free end of the water scraping plate abuts against the surface of the rubber blanket. The water scraping plate will reliably abut against the surface of the rubber blanket under the action of the torsion spring. During operation, when water adheres to the surface of the rubber blanket and moves to the position where the water scraping mechanism is located with it, the water scraping plate will scrape off this water, which can effectively prevent the cooling water from moving to the pressure drying cylinder along with the rubber blanket and affecting the pre-shrinking effect.

[0005] In the existing technical solution, the water squeezing and treatment is carried out by setting a water scraping mechanism. When the free end of the water scraping plate abuts against the surface of the rubber blanket and water adheres to the surface of the rubber blanket and moves to the position where the water scraping mechanism is located with it, the water scraping plate will scrape off this water, so as to achieve the effect of removing water. However, since the water scraping plate abuts against the surface of the rubber blanket, scratches will be caused on the surface layer of the rubber blanket during water scraping, thus affecting the quality of the rubber blanket. Summary of the Invention

[0006] The purpose of the utility model is to provide a rubber blanket water squeezing and treatment device for a pre-shrinking machine. The water squeezing roller rotates to squeeze the rubber blanket inside and outside, which can more effectively remove the attached water on the surface of the rubber blanket. This mechanical squeezing method is more thorough than simply scraping water by the water scraping plate, improving the water squeezing efficiency. The water scraping plate may cause certain wear on the surface of the rubber blanket during the water scraping process, while the water squeezing roller works by rolling extrusion, with relatively less wear on the rubber blanket, which helps to extend the service life of the rubber blanket, so as to solve the problems raised in the above background technique.

[0007] To achieve the above object, the present utility model provides the following technical solution: A water squeezing device for the rubber blanket of a pre-shrinking machine, comprising a bracket. A short shaft penetrates through the bottom end inside the bracket, and a support arm is rotatably connected to the end of the short shaft away from the bracket. In front of the short shaft, there is a cylinder fixedly installed on the side wall of the bracket. The upper end of the cylinder is detachably installed with a bolt, and a guide groove is provided at the connection between the support arm and the bolt.

[0008] The front end of the support arm is provided with a water squeezing roller assembly. The water squeezing roller assembly includes a core shaft fixedly installed at the front end inside the support arm, and a water squeezing roller is rotatably installed on the core shaft.

[0009] Preferably, a fixing nut is fixedly installed at the connection between the core shaft and the support arm. Bearing grooves are provided at both ends inside the water squeezing roller, and bearings are installed inside the bearing grooves.

[0010] Preferably, the support arm is rotatably connected to the bracket through the short shaft, and two groups of the support arm, the cylinder, the fixing nut, the bolt, the short shaft and the guide groove are symmetrically installed.

[0011] Preferably, dust-proof end caps are fixedly installed at both ends of the water squeezing roller. Fixing screws are equiangularly installed at the edge of the outer end face of the dust-proof end cap, and the number of the fixing screws is six.

[0012] Preferably, a rubber blanket guide roller is rotatably installed inside the bracket, and a rubber blanket is attached to the outer end face of the rubber blanket guide roller.

[0013] Preferably, a roller surface coating is provided on the end face of the water squeezing roller. The material of the roller surface coating is hard chromium material, and the material of the water squeezing roller is 45# steel material.

[0014] Preferably, the length of the water squeezing roller is greater than the length of the rubber blanket guide roller, and the length of the rubber blanket guide roller is greater than the width of the rubber blanket.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. The water squeezing roller of the present utility model squeezes the rubber blanket both inside and outside by rotation, which can more effectively remove the attached water on the surface of the rubber blanket. This mechanical squeezing method is more thorough than simply scraping water with a water scraping plate, improving the water squeezing efficiency. During the rotation of the water squeezing roller, pressure can be evenly applied to the rubber blanket, ensuring that the water in all parts of the rubber blanket can be effectively removed, avoiding the problem of local residual water caused by uneven water scraping of the water scraping plate. The water scraping plate may cause certain wear to the surface of the rubber blanket during the water scraping process, while the water squeezing roller works by rolling extrusion, with relatively less wear on the rubber blanket, which helps to extend the service life of the rubber blanket.

[0017] 2. The utility model improves the water squeezing effect and reduces the water content of the rubber blanket by means of the hard chromium plating on the surface of the water squeezing roller and applying the extrusion force of the air cylinder, which can effectively avoid the occurrence of water spots and water bubbles and reduce the rework cost; by setting the dust-proof end cover, the problem of water and dust entering the bearing can be effectively avoided, and the service life of the bearing can be prolonged.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0026] The present utility model provides a technical solution:

[0027] Please refer to Figures 1 to 4, A water squeezing device for the rubber blanket of a pre-shrinking machine, including a bracket 9 which can play a supporting role. A short shaft 6 penetrates through the bottom end inside the bracket 9. One end of the short shaft 6 away from the bracket 9 is rotatably connected to a support arm 2. In front of the short shaft 6, there is a cylinder 3 fixedly installed on the side wall of the bracket 9. The upper end of the cylinder 3 is detachably installed with a pin 5. A guide groove 10 is provided at the connection between the support arm 2 and the pin 5. The setting of the guide groove 10 can prevent interference between the telescopic pushing movement of the cylinder 3 and the rotational movement of the support arm 2. The front end of the support arm 2 is provided with a water squeezing roller assembly 1. The water squeezing roller assembly 1 includes a mandrel 103 fixedly installed at the front end inside the support arm 2. A water squeezing roller 101 is rotatably installed on the mandrel 103. A fixing nut 4 is fixedly installed at the connection between the mandrel 103 and the support arm 2. The support arm 2 is rotatably connected to the bracket 9 through the short shaft 6. Two groups of the support arm 2, the cylinder 3, the fixing nut 4, the pin 5, the short shaft 6 and the guide groove 10 are symmetrically installed. An rubber blanket guide roller 8 is rotatably installed inside the bracket 9, and an rubber blanket 7 is attached to the outer end face of the rubber blanket guide roller 8.

[0028] By adopting the above technical solution, the rubber blanket 7 needs cold water spraying to continuously cool down. Since the surface of the rubber blanket 7 is rough and uneven, it is difficult to remove the water on the surface. By applying force through the cylinder 3 and using the short shaft 6 as a fulcrum, the support arm 2 is lifted, so that the water squeezing roller 101 contacts and applies pressure to the rubber blanket 7. Since the rubber blanket guide roller 8 and the water squeezing roller 101 are on both sides of the same point of the rubber blanket 7, a squeezing state is formed on the rubber blanket 7, causing the rubber blanket 7 to deform, increasing the contact area between the water squeezing roller 101 and the rubber blanket 7, and thus squeezing out the water on the outer surface of the rubber blanket 7. Therefore, compared with scraping water by a water scraping plate, the water squeezing roller 101 rotates to perform internal and external extrusion on the rubber blanket, and can more effectively remove the attached water on the surface of the rubber blanket. This mechanical extrusion method is more thorough than simply scraping water by a water scraping plate, improving the water squeezing efficiency. During the rotation process, the water squeezing roller 101 can evenly apply pressure to the rubber blanket, ensuring that the water in each part of the rubber blanket can be effectively removed, avoiding the problem of local residual water caused by uneven water scraping by the water scraping plate. The water scraping plate may cause certain wear on the surface of the rubber blanket during the water scraping process, while the water squeezing roller 101 works by rolling extrusion, with relatively less wear on the rubber blanket, which helps to extend the service life of the rubber blanket.

[0029] Specifically, as Figure 2 and Figure 4As shown in the figure, bearing grooves 102 are provided at both inner ends of the water squeezing roller 101. Bearings 107 are installed inside the bearing grooves 102. Dust-proof end caps 104 are fixedly installed at both ends of the water squeezing roller 101. Fixing screws 105 are installed at equal angles on the outer end face edge of the dust-proof end cap 104. The number of fixing screws 105 is set to six. A roller surface coating 106 is provided on the end face of the water squeezing roller 101. The material of the roller surface coating 106 is hard chromium. The material of the water squeezing roller 101 is 45# steel. The length of the water squeezing roller 101 is greater than the length of the rubber blanket guide roller 8, and the length of the rubber blanket guide roller 8 is greater than the width of the rubber blanket 7.

[0030] By adopting the above technical solutions, the rotation of the water squeezing roller body 101 of the water squeezing roller 101 is realized through the bearings 107 in the bearing grooves 102, while the mandrel 103 is firmly fixed to the support arm 2 and does not rotate. There is a roller surface coating 106 outside the water squeezing roller 101 to protect the water squeezing roller 101 from rusting and swelling, ensuring that the surface of the rubber blanket 7 can be evenly pressed. The material of the roller surface coating 106 is hard chromium, and the high hardness of hard chromium can improve the water squeezing effect. The support arm 2 takes the short shaft 6 as the fulcrum, and the water squeezing roller 101 is lifted by the force applied by the air cylinder 3. The acting points of the water squeezing roller 101 and the rubber blanket guide roller 8 are on both sides of the same position of the rubber blanket 7, ensuring that the extrusion force is concentrated. By the hard chromium coating on the surface of the water squeezing roller 101 and the extrusion force applied by the air cylinder 3, the water squeezing effect is improved, the water content of the rubber blanket 7 is reduced, the occurrence of water spot and water bubble problems can be effectively avoided, and the rework cost is reduced; by setting the dust-proof end cap 104, the problem of water and dust entering the bearing 107 can be effectively avoided, and the service life of the bearing 107 is improved.

[0031] Working principle: During use, the rubber blanket 7 needs to be continuously cooled by cold water spraying. Since the surface of the rubber blanket 7 is rough and uneven, it is difficult to remove the water on the surface. By applying force with the air cylinder 3 and taking the short shaft 6 as the fulcrum, the support arm 2 is lifted to make the water squeezing roller 101 contact and apply pressure to the rubber blanket 7. Since the rubber blanket guide roller 8 and the water squeezing roller 101 are on both sides of the same point of the rubber blanket 7, an extrusion state is formed on the rubber blanket 7, causing the rubber blanket 7 to deform, increasing the contact area between the water squeezing roller 101 and the rubber blanket 7, and thus squeezing out the water on the outer surface of the rubber blanket 7. The rotation of the water squeezing roller body 101 of the water squeezing roller 101 is realized through the bearings 107 in the bearing grooves 102, while the mandrel 103 is firmly fixed to the support arm 2 and does not rotate. There is a roller surface coating 106 outside the water squeezing roller 101 to protect the water squeezing roller 101 from rusting and swelling, ensuring that the surface of the rubber blanket 7 can be evenly pressed. The material of the roller surface coating 106 is hard chromium, and the high hardness of hard chromium can improve the water squeezing effect. The support arm 2 takes the short shaft 6 as the fulcrum, and the water squeezing roller 101 is lifted by the force applied by the air cylinder 3. The acting points of the water squeezing roller 101 and the rubber blanket guide roller 8 are on both sides of the same position of the rubber blanket 7, ensuring that the extrusion force is concentrated.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
