Description

Technical Field

[0001] The invention belongs to the technical field of rubber calenders, in particular to a calendering device for producing conveyor belts. Background Art

[0002] The calendering process of rubber first uses an open mill to rough and finely refine the mixed rubber sheet, or feeds the calender through a pin-type cold feed extruder. If the product contains fabric, the fabric is dried after passing through a guide device, and is sent to the calender after a certain tension. It is stretched and extruded by the calender roller to form a rubber sheet or rubber cord fabric, which is then cooled and finally wound up. The calendering process is the same as the calendering of plastics. The main process is to use two rollers to roll the rubber into a film with a certain thickness and density.

[0003] During the operation of the rubber calender, there is a prominent problem. When the rubber material passes through the calender roller, due to the high temperature of the rubber material, it is in a relatively soft and sticky state. The rubber material at this high temperature is very easy to stick to the outer wall of the calender roller.

[0004] As the calender roller rotates, the sticky rubber comes into contact with the rubber product again, which will not only affect the surface quality of the rubber product, causing problems such as unevenness and uneven thickness of the product, but also reduce the working efficiency of the calender. Frequent manual cleaning of sticky rubber will increase production costs and operating difficulty, thereby affecting the stability and sustainability of the entire rubber calendering production.

DETAILED DESCRIPTION

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0042] like Figures 1 to 11 As shown, a calendering device for conveyor belt production described in the present invention includes a calendering mechanism, a driving mechanism, a scraping mechanism, a control mechanism and a recovery mechanism.

[0043] The calendering mechanism installation bracket 1, the calendering roller 6 and the transmission shaft 9, the transmission shaft 9 is fixedly installed on the axial end of the calendering roller 6, and the calendering roller 6 is rotatably connected to the installation bracket 1 through the transmission shaft 9, wherein the transmission shaft 9 is connected to the installation bracket 1 through the cooperation of the bearing and the bearing seat.

[0044] The driving mechanism is used to drive the transmission shaft 9 to rotate along its own axis. There are two calendering rollers 6. To complete the calendering operation, it is necessary to control the two calendering rollers 6 to rotate synchronously towards each other. Two mutually meshing gears are arranged at one end of the transmission shaft 9 outside the two calendering rollers 6. At this time, by controlling one of the calendering rollers 6 to rotate, the other calendering roller 6 can be controlled to rotate, so as to realize the calendering operation.

[0045] The scraping mechanism includes a scraping frame 5 and a guide plate 14. The scraping frame 5 is fixedly mounted on the side wall of the mounting bracket 1, and the outer wall of the scraping frame 5 is slidingly fitted with the radial outer wall of the calendering roller 6. During the rotation of the calendering roller 6, the rubber sticking to its outer wall is scraped by the outer wall of the scraping frame 5, so that the adhered rubber falls off to the inner cavity of the scraping frame 5. By scraping the rubber sticking to the outer wall of the calendering roller 6, the sticky rubber can be prevented from contacting the material again, and depressions and protrusions can be prevented from appearing on the surface of the rubber after calendering, thereby improving the production quality of the conveyor belt.

[0046] In order to facilitate the scraped rubber to fall into the inner cavity of the scraping frame 5, the inner wall of the scraping frame 5 on the side in contact with the calendering roller 6 is inclined. When the calendering roller 6 rotates, the sticky rubber is pushed along the inclined surface of the scraping frame 5 and falls into the interior of the scraping frame 5.

[0047] The guide plate 14 is made of elastic material and is elastically installed on the inner wall of the scraping frame 5. The guide plate 14 is tilted. After the rubber falling off the outer wall of the calender roller 6 falls into the inner cavity of the scraping frame 5, it gradually cools down. At this time, the guide plate 14 is rotated by tapping, so that the scraped rubber slides along the inclined surface of the guide plate 14 until it is discharged from one end of the guide plate 14, so as to facilitate the recycling of the scraped rubber.

[0048] The control mechanism includes a bearing plate 13 , a mounting tube 12 and a knocking shaft 20 . The bearing plate 13 is fixedly mounted on the bottom of the scraping frame 5 , and the mounting tube 12 is fixedly mounted on the inner wall of the bearing plate 13 . The bearing plate 13 provides mounting and support for the mounting tube 12 .

[0049] The tapping shaft 20 is elastically arranged in the mounting tube 12 and is used to tap the bottom of the guide plate 14. The elastic force exerted on the tapping shaft 20 is used to pull the tapping shaft 20 to control the tapping shaft 20 to tap the bottom surface of the guide plate 14, thereby driving the guide plate 14 to vibrate and realize the discharge of the collected rubber.

[0050] The recovery mechanism is used to recover the residue discharged from one end of the guide plate 14, so as to realize the recovery of the scraped rubber.

[0051] The control motor 4 is fixedly mounted on the upper end surface of the support frame 3 , and the control box 2 is fixedly mounted on the upper end surface of the support frame 3 . The support frame 3 is a steel frame structure made of angle steel, and the support frame 3 provides installation and support for the control motor 4 .

[0052] The control worm wheel 11 and the control worm 10 are both rotatably mounted on the inner wall of the control box 2 , and the control worm wheel 11 and the control worm 10 are meshed with each other. Rotating the control worm 10 drives the control worm wheel 11 to rotate.

[0053] One end of the control worm 10 is fixedly connected to the output shaft of the control motor 4, and the axial end of the control worm wheel 11 is connected to the transmission shaft 9 through a transmission member. In this embodiment, the transmission member uses a common belt and pulley. The control motor 4 drives the control worm 10 to control the worm wheel 11 to rotate, thereby driving the transmission shaft 9 and the calendering roller 6 to rotate, providing power for rubber calendering.

[0054] The recovery mechanism includes a guide frame 15, a crushing barrel 29 and a discharge hopper 24. The outer wall of the guide frame 15 is fixedly connected to the side wall of the mounting bracket 1, and the other end of the guide frame 15 is fixedly connected to the outer wall of the bearing plate 13. When the guide plate 14 vibrates, the collected rubber is controlled to be discharged into the inner cavity of the guide frame 15 and falls downward under gravity.

[0055] The crushing drum 29 is fixedly mounted on the outer wall of the supporting frame 3 , the bottom of the guide frame 15 is fixedly connected to the upper end surface of the crushing drum 29 , and the discharge hopper 24 is fixedly mounted on the bottom of the crushing drum 29 . After the rubber in the guide frame 15 falls into the crushing drum 29 , it is discharged through the discharge hopper 24 .

[0056] As a preferred embodiment of the present invention, a guide tube 19 is fixedly installed on the inner wall of the mounting tube 12, and a sliding plate 18 is elastically installed on the inner wall of the guide tube 19. The upper end surface of the sliding plate 18 is fixedly connected to the bottom surface of the tapping shaft 20. A spring is provided on the upper end surface of the sliding plate 18, and the other end of the spring is fixedly connected to the inner wall of the guide tube 19. The sliding adjustment sliding plate 18 drives the tapping shaft 20 to slide. After being released, the elastic force of the spring drives the sliding plate 18 and the tapping shaft 20 to slide, thereby realizing the tapping of the guide plate 14.

[0057] A magnetic plate 17 is fixedly mounted on the bottom surface of the sliding plate 18 . The magnetic plate 17 is a common magnet. A control ring 36 is slidably mounted between the mounting tube 12 and the guide tube 19 . The control ring 36 is an iron ring.

[0058] The outer wall of the control ring 36 is sealed to the inner wall of the mounting tube 12, and the inner wall of the control ring 36 is sealed to the outer wall of the guide tube 19, wherein the outer wall and the inner wall of the control ring 36 are both provided with sealing rubber rings, and the control ring 36 and the guide tube 19 and the mounting tube 12 are sealedly connected. At this time, the air pressure in the chamber between the mounting tube 12 and the guide tube 19 is adjusted to drive the control ring 36 to slide.

[0059] During the sliding of the control ring 36, the sliding plate 18 is driven to slide by the magnetic force between the control ring 36 and the magnetic plate 17 until the magnetic force between the magnetic plate 17 and the control ring 36 is smaller than the elastic force exerted on the sliding plate 18. At this time, the elastic force of the spring pulls the sliding plate 18 until the tapping shaft 20 taps the guide plate 14, so as to control the discharge of the collected rubber.

[0060] After the tapping shaft 20 taps the guide plate 14, the control ring 36 is slid in the reverse direction until the magnetic force between the magnetic plate 17 and the control ring 36 is again greater than the elastic force on the sliding plate 18, so that the sliding plate 18 can be controlled to slide again by sliding the control ring 36, so that the tapping shaft 20 taps the guide plate 14 again.

[0061] A support tube 8 is fixedly mounted on the outside of the mounting bracket 1 , and an elastic block 22 is fixedly mounted on the inner wall of the support tube 8 . The elastic block 22 is made of rubber.

[0062] A cavity is provided inside the elastic block 22, and a transfer tube 7 is fixedly installed on the outer wall of the support tube 8. One end of the transfer tube 7 is connected with the inner cavity of the elastic block 22, and the other end of the transfer tube 7 is connected with the inner cavity of the mounting tube 12. The elastic block 22 is pressed to discharge the air inside the elastic block 22 out of the cavity between the mounting tube 12 and the guide tube 19. At this time, the control ring 36 slides upward. After the elastic block 22 is released, the elastic block 22 is reset to suck out the air in the cavity between the mounting tube 12 and the guide tube 19. At this time, the control ring 36 slides downward.

[0063] An arc plate 23 is fixedly installed on the inner wall of the elastic block 22. The arc plate 23 is made of elastic material, and the outer wall fits the inner wall of the elastic block 22. The arc plate 23 is a common elastic copper plate. After pressing the elastic block 22, the elastic force of the arc plate 23 assists the elastic block 22 to reset, preventing the elastic block 22 from remaining concave after pressing the elastic block 22.

[0064] The transmission shaft 9 passes through the support tube 8 and a transmission cam 21 for pressing the elastic block 22 is fixedly installed on the radial outer wall. The transmission shaft 9 drives the transmission cam 21 to rotate during rotation, and the elastic block 22 is pressed by the transmission cam 21. After the transmission cam 21 and the elastic block 22 are separated, the elastic block 22 restores its elastic deformation to drive the control ring 36 to slide back and forth.

[0065] In order to facilitate the vibration of the guide plate 14, a load-bearing beam 16 is fixedly installed on the upper end surface of the load-bearing plate 13. The upper end surface of the load-bearing beam 16 is slidably connected to the bottom surface of the guide plate 14. A spring is arranged above the load-bearing beam 16, and the other end of the spring is connected to the guide plate 14, so that the guide plate 14 can vibrate when it is tapped.

[0066] As a preferred embodiment of the present invention, a screening plate 26 is fixedly installed on the inner wall of the crushing cylinder 29 . The screening plate 26 is a common mesh plate and is used to screen the rubber entering the crushing cylinder 29 .

[0067] The inner wall of the crushing cylinder 29 is fixedly installed with a mounting box 25, and the inner wall of the mounting box 25 is fixedly installed with a crushing motor 33. The output shaft of the crushing motor 33 extends to the upper end surface of the screening plate 26 and is fixedly installed with a crushing plate 30. The crushing plate 30 is inclined and has a blade at the edge. The crushing motor 33 drives the crushing plate 30 to rotate, and the rubber that has not passed through the screening plate 26 is crushed, and then screened through the screening plate 26. The collected rubber is crushed and then recycled, which is beneficial to subsequent recycling and processing.

[0068] As a preferred embodiment of the present invention, a guide cylinder 27 is fixedly mounted on the inner wall of the crushing cylinder 29 , and the crushing cylinder 29 provides a mounting support position for the guide cylinder 27 .

[0069] A control rod is elastically mounted on the inner wall of the guide cylinder 27 , and a spring is disposed on the outer wall of one end of the control rod located inside the guide cylinder 27 , and the other end of the spring is fixedly connected to the outer wall of the guide cylinder 27 .

[0070] One end of the control rod extends to the outside of the guide cylinder 27 and is fixedly installed with an auxiliary plate 28. The bottom of the auxiliary plate 28 is slidably fitted with the outer wall of the crushing plate 30. The edge of the auxiliary plate 28 is provided with a cutting edge that is the same as that of the crushing plate 30. The elastic force exerted on the control rod makes the auxiliary plate 28 tend to approach the crushing plate 30 in real time, thereby improving the efficiency of rubber shear crushing during the rotation of the crushing plate 30.

[0071] A mounting block 32 is fixedly mounted on the inner wall of the mounting box 25 , an elastic rod 31 is elastically mounted on the inner wall of the mounting block 32 , a spring is fixedly mounted on the outer wall of the elastic rod 31 , and the other end of the spring is fixed to the inner wall of the mounting block 32 .

[0072] The bottom surface of the elastic rod 31 passes through the mounting block 32 and fits with the bottom surface of the screening plate 26. During the screening process of the screening plate 26, the elastic rod 31 slides and taps the bottom surface of the screening plate 26 to facilitate the small rubber particles to pass through the screening plate 26. At the same time, the vibration generated by tapping the screening plate 26 bounces up the large rubber particles, so that the crushing plate 30 can crush the large rubber particles.

[0073] A toggle rod 34 is fixedly installed on the outer wall of the output shaft of the crushing motor 33, and the side wall of the toggle rod 34 is inclined. A transmission groove 35 is opened on the outer wall of the elastic rod 31, and the inner wall of the transmission groove 35 is inclined. When the crushing motor 33 controls the rotation of the crushing plate 30, the toggle rod 34 is synchronously driven to rotate, and the toggle rod 34 slides along the inclined surface of the transmission groove 35, thereby pressing the elastic rod 31 downward. At this time, the elasticity of the outer wall of the elastic rod 31 stores elastic potential energy. As the toggle rod 34 rotates, the toggle rod 34 separates from the elastic rod 31. At this time, the elastic rod 31 knocks on the bottom surface of the screening plate 26 to complete the knocking of the screening plate 26.

Figure 1 As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
