Description

Technical Field

[0001] The present invention relates to the technical field of composite sealing strip production, and particularly relates to a putty composite sealing strip production line. Background Art

[0002] In the field of putty composite sealing strip manufacturing, there are no advanced production devices. Currently, the production devices used in the industry for putty composite sealing strips usually only have extruders and no other auxiliary devices, resulting in very low production efficiency and unstable quality. The application field of putty composite sealing strips is in the waterproof sealing of the interfaces of precast concrete integrated pipe galleries. Precast concrete integrated pipe galleries are century projects and livelihood projects, with very high quality requirements, and also very high requirements for the waterproof effect of putty composite sealing strips. Due to the lack of advanced production devices for putty composite sealing strips at present, their production efficiency and quality cannot keep up with the development of precast concrete integrated pipe galleries, severely restricting the overall development of this industry. In addition, due to low production efficiency, a large amount of labor and multiple devices are required for production to meet the usage needs, greatly increasing the production cost of the products. In today's era of labor shortage, a large demand for labor adds burdens to enterprises and also increases the social burden. Summary of the Invention

[0003] The purpose of the present invention is to develop a putty composite sealing strip production line to solve the problems of low production efficiency and low production quality of existing putty composite sealing strips.

[0004] The present invention is achieved through the following technical solutions:

An efficiency enhancing device for compounding and forming the materials with the to-be-compounded sealing strips is provided at the outlet of the flow dividing device, and several composite sealing strips can be produced simultaneously. The shaping machine includes a first winding roller for receiving the composite sealing strips extruded by the extruder and a second winding roller for receiving the composite sealing strips wound by the first winding roller. The first winding roller is arranged above the second winding roller, and their axial projections on the horizontal plane intersect. The composite sealing strips are shaped in the shaping machine, and the cooling time of the composite sealing strips is increased through the first and second winding rollers, so that the cooling effect is better and the quality of the composite sealing strips is ensured. The automatic length measuring and coiling machine includes coiling discs having the same number as the efficiency enhancing device and a measuring device for measuring the length of the composite sealing strips. The measuring device is arranged on the movement track of the composite sealing strips entering the coiling discs.

[0009] Furthermore, the axis of the first winding roller is perpendicular to the traveling and transporting direction of the compounded seal strip, and the axis of the second winding roller is inclined to the traveling and transporting direction of the compounded seal strip. The projections of the axes of the two winding rollers on the horizontal plane intersect, so that the compounded seal strips on the same roller do not contact each other, ensuring the quality of the compounded seal strip.

[0010] Furthermore, the shaping machine further includes a machine box body for accommodating the first winding roller and the second winding roller. A nozzle is provided above the first winding roller on the machine box body, and the nozzles are evenly arranged along the axial direction of the first winding roller. The water sprayed by the nozzles increases the cooling rate of the compounded seal strip.

[0011] Furthermore, a water tank for receiving the water sprayed by the nozzles is provided below the second winding roller on the machine box body to collect the water for recycling.

[0012] Furthermore, the automatic length measuring and coiling machine further includes a base for placing the coiling disk. A support rod is provided on the base.

[0013] Furthermore, an isolating paper coiling disk is further provided on the adjusting plate, and the isolating paper coiling disk is arranged above or below the measuring device.

[0014] Furthermore, a connecting plate is further provided on the base.

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] like Figures 1 to 4As shown in the figure, the present invention discloses a putty composite sealing strip production line, which includes an extruder 1, a shaping machine 2 and an automatic length measuring and coiling machine 3. All the electronic devices on the production line are connected to the control cabinet 30 by wires. According to the production process flow of the putty composite sealing strip, the sealing strip sequentially passes through the extruder 1, the shaping machine 2 and the automatic length measuring and coiling machine 3. After the putty is added to the extruder 1, the rotating screw in the extruder 1 pushes the putty, and the pushed putty is mixed with the sealing strip, and a preliminary putty composite sealing strip product is formed after mixing. The rollers of the shaping machine 2 are arranged in a staggered manner, so that the passing time of the putty composite sealing strip in the shaping machine 2 is increased, enabling the shaping machine 2 to have sufficient time to cool the putty composite sealing strip. The cooled putty composite sealing strip has a stable structure due to the temperature reduction. The length is measured by the automatic length measuring and coiling machine 3 and coiled, thus completing the production of the putty composite sealing strip.

[0026] The extruder 1 is a screw extruder 1, which includes a base 10. The base 10 is rectangular in shape. One end of the base 10 is provided with a motor box, and a motor is arranged in the motor box. A gearbox is arranged above the motor box. The driving wheel of the motor is in transmission connection with the driven wheel of the gearbox. The other end of the base 10 is provided with a support plate, and a pipe clamp is arranged on the support plate. The conveying pipe of the extruder 1 is arranged in the pipe clamp. The discharge port 13 of the conveying pipe is located at the pipe clamp. The other end of the conveying pipe is connected to the gearbox. The conveying pipe is horizontally arranged. A second constant temperature device 11 is arranged on the conveying pipe. The second constant temperature device 11 includes a heating sleeve, and the heating sleeve is a heating resistor. An inlet 12 is arranged above the conveying pipe. The heated putty enters the conveying pipe from the inlet 12. A screw is arranged in the conveying pipe. The maximum diameter of the screw is the same as the inner diameter of the conveying pipe. The screw is in transmission connection with the gearbox. The motor drives the gearbox, and the gearbox drives the screw to rotate in the conveying pipe. After the putty enters the conveying pipe through the inlet 12, it is in the spiral groove of the screw, and the rotating screw pushes the putty forward.

[0027] The discharge port 13 of the conveying pipe is connected to the flow dividing device 14. The flow dividing device 14 is of a "T"-shaped pipe structure. The putty output from the discharge port 13 of the conveying pipe flows through the flow dividing device 14 to the outlets at both ends thereof. The function of the flow dividing device 14 is to divide the putty into multiple flow channels. At each of the outlets at both ends of the flow dividing device 14, there is provided an efficiency enhancing device 15. The efficiency enhancing device 15 is of a straight pipe structure. One end of the efficiency enhancing device 15 is an efficiency enhancing head 150. The efficiency enhancing head 150 is provided with an inlet for the sealing strip to be compounded. The efficiency enhancing head 150 is provided with holes, and the shape and size of the holes are the same as those of the cross-section of the sealing strip to enter. The other end of the efficiency enhancing device 15 is an efficiency enhancing tail 151. After the putty is compounded with the sealing strip in the efficiency enhancing device 15, it is output from the efficiency enhancing tail 151. The efficiency enhancing tail 151 is also provided with holes, and the shape and size of the holes are the same as those of the cross-section of the putty compounded with the sealing strip. On the efficiency enhancing tail 151 of the efficiency enhancing device 15, there is provided a first constant temperature device 152. The first constant temperature device 152 is similar in structure to the second constant temperature device 11, and both are heating sleeves, which keep the equipment at a certain temperature and keep the putty at a certain temperature, being beneficial to the conveying or shaping of the putty. Both the efficiency enhancing head 150 and the efficiency enhancing tail 151 can be replaced according to production requirements for the entry of sealing strips with different cross-sections and the output of the putty compounded with the sealing strips.

[0028] The shaping machine 2 includes a machine box body 20. The outer shape of the machine box body 20 is a cuboid. A bracket is provided inside the machine box body 20, and all components inside the machine box body 20 are arranged on the bracket. A motor and an inverter electrically connected to the motor are provided at the bottom of the machine box body 20. Above the motor, there is a water tank 25. The water tank 25 is a square water tank 25. A drain port is provided at the bottom of the water tank 25, and the drain port is connected to a water delivery pipe. A micro pump is provided on the water delivery pipe, and the micro pump is arranged on the bracket below the water tank 25. Above the water tank 25, there is a second winding roller 24. Both ends of the second winding roller 24 are arranged above the square water tank 25. Both ends of the second winding roller 24 are connected to two bearings arranged on the water tank 25. The second winding roller 24 can rotate above the water tank 25. Above the second winding roller 24, there is a first winding roller 23. The first winding roller 23 is similar in structure to the second winding roller 24. The difference is that the length of the first winding roller 23 is less than that of the second winding roller 24. Both ends of the first winding roller 23 are connected to two bearings fixedly arranged on the bracket. The first winding roller 23 and the second winding roller 24 are not parallel in the same horizontal plane and have a certain angle, that is, the projections of the axial directions of the first winding roller 23 and the second winding roller 24 on the square water tank 25 intersect, and the intersection point is the midpoint of each of the two projection lines. And the projection of the axial direction of the first winding roller 23 on the water tank 25 is perpendicular to or parallel to two sides of the water tank 25. The axial direction of the first winding roller 23 is perpendicular to the traveling and transmission direction of the composite sealing strip, and the axial direction of the second winding roller 24 is inclined to the traveling and transmission direction of the composite sealing strip.One end of the first winding roller 23 and the second winding roller 24 is also provided with a gear, and the gear is in transmission connection with a motor arranged at the lower part of the water tank 25. A water injection pipe 21 is also arranged at the top of the machine box body 20 of the shaping machine 2. The water injection pipe 21 is arranged directly above the first winding roller 23. One end of the water injection pipe 21 is blocked, and the other end is connected to a water inlet and a water delivery pipe. A number of spray heads 22 are arranged on the water injection pipe 21, and all the spray heads 22 are arranged directly above the first winding roller 23. After the putty composite sealing strip enters the shaping machine 2, it first enters the upper part of the first winding roller 23, then enters the second winding roller 24, returns from the second winding roller 24 to the first winding roller 23, and finally is output from the first winding roller 23. Since the second winding roller 24 is misaligned with the first winding roller 23, there is a certain angle between their projections, which increases the travel of the putty composite sealing strip and increases the passing time of the putty composite sealing strip in the shaping machine 2. Moreover, the putty composite sealing strips on the same winding roller do not contact each other, preventing adhesion caused by contact and thus damaging the putty on the outside of the putty composite sealing strip. During this process, the spray heads 22 below the water injection pipe 21 spray water, and the sprayed water cools the putty composite sealing strip. The temperature of the cooled putty structure is not easy to deform. The water sprayed by the spray heads 22 to cool the putty composite sealing strip falls into the water tank 25 below the second winding roller 24 and enters the water delivery pipe from the drain outlet at the bottom of the water tank 25. The micro pump transports the water in the water delivery pipe to the water injection pipe 21 to realize the reuse of water and save water resources.

[0029] The automatic length measuring coiling machine 3 includes a base 37, the outer shape of which is also a cuboid. A motor and an inverter connected to the motor by wires are provided at the bottom of the base 37. Two coiling discs 34 are provided on the side of the base 37. The centers of the two coiling discs 34 are located on the same horizontal line. A transmission shaft is provided at the center of the coiling disc 34, and the transmission shaft is in transmission connection with the motor. A coiler 33 is also provided at the center of the coiling disc 34. The outer shape of the coiler 33 is similar to a cone. The circles at the bottom and top of the coiler 33 are concentric circles. The diameter of the circle at the bottom of the coiler 33 is larger than that of the circle at the top. The top of the coiler 33 is coaxially connected to the transmission shaft. Such a structure prevents the putty composite sealing strip from falling off the coiler 33. The motor drives the transmission shaft, and the coiling disc 34 and the coiler 33 rotate coaxially and synchronously. Two buffer rollers 35 are provided on the top of the base 37. By adjusting the friction pair of the buffer rollers 35, the rotation of the buffer rollers 35 has a certain resistance. The buffer rollers 35 are arranged on a connecting plate, and the connecting plate is fixed on the top of the base 37. The two buffer rollers 35 are respectively arranged beside the two coiling discs 34 and are on the movement track of the putty composite sealing strip. The horizontal height of the buffer rollers 35 is slightly higher than the top of the coiling discs 34. Two measuring devices are also provided on the top of the base 37. The measuring device includes a support rod. The bottom of the support rod is connected to the base 37 and is perpendicular to the top of the base 37. An adjusting plate 36 is provided on the support rod. A number of holes are provided on the adjusting plate 36. A proximity switch and a length measuring roller 32 (i.e., a part of the measuring device) are provided on the adjusting plate 36. The proximity switch is arranged on the side of the length measuring roller 32. An induction piece is provided on the circumferential side of the length measuring roller 32. When the induction piece approaches the proximity switch as the length measuring roller 32 rotates one week, the proximity switch will obtain a signal and transmit this signal to the counter in the control cabinet 30, thereby recording the number of rotations of the length measuring roller 32. The circumference of the length measuring roller 32 is certain, and the product of the circumference and the number of rotations is the total length of the rotation of the length measuring roller 32, that is, the length of the putty composite sealing strip. A support rod is also provided on the adjusting plate 36. An isolation paper coiling disc 31 is provided on the support rod. The isolation paper coiling disc 31 is located above the length measuring roller 32. By adjusting the friction pair of the isolation paper coiling disc 31, the rotation of the isolation paper coiling disc 31 has a certain resistance, so that the isolation paper maintains a certain tension, and the isolation paper can be coiled on the isolation paper coiling disc 31. The components on the adjusting plate 36 are bolted to the adjusting plate 36 through the holes on the adjusting plate 36, and the positions of the components on the adjusting plate 36 can be adjusted on the adjusting plate 36. A control cabinet 30 is also provided on the top of the base 37. A display screen is provided on the control cabinet 30, which can display some specific parameters of the production line equipment.The putty composite sealing strip enters the length measuring roller 32 through the buffer roller 35. Since the rotation of the buffer roller 35 has a certain resistance, it plays a certain role in decelerating the conveyance of the putty composite sealing strip. After the putty composite sealing strip enters the length measuring roller 32, it is conveyed on the length measuring roller 32. The length measuring roller 32 moves synchronously with the putty composite sealing strip, and thus the length of the putty composite sealing strip is measured. Then it enters the coiler 33 from the length measuring roller 32. At this time, the release paper on the release paper reel 31 contacts the putty composite sealing strip and moves together into the coiling disc 34 to be coiled by the coiler 33. The release paper prevents the direct contact between the putty composite sealing strips from causing a decline in product quality.

[0030] When this putty composite sealing strip production line is running, the putty enters the extruder 1 from the feed inlet 12. The rotating screw pushes the putty into the combined pipe. According to production needs, the rotation speed of the screw can be controlled and adjusted through the gearbox. The putty enters the shunt device 14 through the conveying pipe. The putty enters the boosting devices 15 connected to the two ends of the shunt device 14 respectively from the shunt device 14. The sealing strips to be compounded enter the boosting device 15 from the boosting head 150 of the boosting device 15. The putty and the sealing strips are compounded inside the boosting device 15. The compounded putty composite sealing strip is output from the boosting tail 151 of the boosting device 15 and then enters the first winding roller 23 of the shaping machine 2. After winding half a circle on the first winding roller 23, it enters the second winding roller 24 below it. After winding half a circle on the second winding roller 24, it enters the first winding roller 23 again, and finally is output from the top of the first winding roller 23. During this process, the water sprayed by the nozzle 22 at the top of the shaping machine 2 cools the putty composite sealing strip passing through the shaping machine 2. The putty on the surface of the putty composite sealing strip becomes more stable after being cooled. Since the axial projections of the first winding roller 23 and the second winding roller 24 on the horizontal plane have a certain angle and intersect, and the intersection point is the midpoint of each of them, this increases the travel of the putty composite sealing strip inside the shaping machine 2, increases the time it passes through the shaping machine 2, and there is sufficient time for the putty composite sealing strip to cool down. Moreover, the putty composite sealing strips on the same winding roller do not contact each other, preventing the putty on their surfaces from being damaged due to contact and affecting the product quality. The cooling water enters the drainage hopper from the water tank 25 under the winding roller and enters the drain pipe from the drainage hopper. The micro pump transports the water in the drain pipe to the injection pipe 21 and sprays it out from the nozzle 22 of the injection pipe 21, realizing the recycling of water resources.

[0031] After being shaped in the shaping machine 2, the putty composite sealing strip enters the automatic length measuring and coiling machine 3. First, it passes through the buffer roller 35, and the buffer roller 35 has a certain decelerating effect on the putty composite sealing strip. Then it enters the length measuring roller 32 from the buffer roller 35. The putty composite sealing strip moves synchronously with the length measuring roller 32. The release paper on the release paper reel 31 above the length measuring roller 32 contacts and moves synchronously with the putty composite sealing strip. The release paper wraps around the outside of the putty composite sealing strip and is curled by the coiler 33 in the middle of the coiling reel 34 together with the putty composite sealing strip. The release paper prevents the putty composite sealing strips from contacting each other and affecting the product quality.

[0032] The above embodiments are only the preferred embodiments of the present invention and do not limit the technical solutions of the present invention. Any technical solutions that can be achieved on the basis of the above embodiments without creative work shall be regarded as falling within the scope of the patent rights of the present invention.
