Description

Technical Field

[0001] The invention relates to the technical field of plastic tube production, in particular to a plastic tube extrusion production device for laparoscopes. Background Art

[0002] In the extrusion production process of laparoscope plastic tubes, the extrusion die is a crucial component, which determines the final shape and size of the plastic tube. However, laparoscope plastic tubes have extremely high requirements for surface quality and smoothness, because they need to operate inside the human body, and the rough surface may cause damage to human tissue, and also affect the imaging effect of the laparoscope and the passability of the instrument. At present, the detection of the surface quality and smoothness of plastic tubes mainly adopts manual visual inspection and some simple contact measurement methods.

[0003] In the extrusion production of plastic tubes for laparoscopes, the uniform dispersion of materials at the feed port directly affects the quality stability of the plastic tubes. Most of the existing feeding methods are to directly put the materials into the hopper of the extruder, and then rely on the rotation of the screw to transport the materials into the extruder. However, this method has the problem of uneven material dispersion.

[0004] During the extrusion production of plastic tubes for laparoscopy, the extruder generates a large amount of waste heat when heating the material and maintaining the production temperature. Currently, most of this waste heat is directly discharged into the surrounding environment, which not only wastes energy, but also causes the temperature of the production workshop to rise, affecting the working environment and the normal operation of the equipment. Summary of the invention

[0005] The purpose of the present invention is to provide a plastic tube extrusion production equipment for laparoscope to solve the problems raised in the prior art.

[0006] To achieve the above object, the present invention provides the following technical solutions:

The mounting platform is placed on a horizontal basis, the driving unit is fixedly mounted on the mounting platform, the driving unit is fixedly connected to the breaking up unit, the breaking up unit has the function of improving the uniformity of the material, the anti-blocking unit is slidably connected to the breaking up unit, the anti-blocking unit is fixedly connected to the detection unit, and the detection unit is rotatably mounted on the driving unit.

[0008] The mounting table is used to install and fix the driving unit, the driving unit is used to drive the device to operate, the breaking unit is used to disperse the material, the anti-blocking unit is used to prevent the material from blocking in the breaking unit, and the detection unit is used to detect the surface smoothness of the finished product. After the material is broken up by the breaking unit, the anti-blocking unit is used to further improve the uniformity of the material. The driving unit heats and melts the material, and the detection unit detects the surface smoothness of the finished product at the die head. The finished product after detection is cooled and formed by the cooling module.

[0009] Furthermore, a waste outlet is provided on the mounting platform, and a control console is provided on the mounting platform.

[0010] In order to facilitate the staff to control the device in time when a machine failure occurs to avoid greater losses.

[0011] Furthermore, the driving unit includes a driving motor, a screw barrel, a screw rod and a slide. The fixed end of the driving motor is slidably mounted on the slide, the output end of the driving motor is fixedly connected to the screw rod, one end of the screw barrel is fixedly mounted on the driving motor housing, the screw rod is mounted inside the screw barrel, the slide is fixedly mounted on the mounting table, and the screw barrel is fixedly connected to the breaking unit.

[0012] The control console controls the drive motor to start, thereby driving the screw to rotate, heating and extruding the material entering the barrel, and then quickly cooling and forming it under the action of the cooling module.

[0013] Furthermore, the disintegration unit includes a feed barrel, a rotating motor, a connecting barrel, a stirring plate, a connecting rod, a filter plate, a buffer spring and a slide plate. The feed barrel is fixedly installed above the screw barrel, and the feed barrel outlet is conductively connected to the screw barrel. The fixed end of the rotating motor is fixedly installed above the feed barrel, and the output end of the rotating motor is fixedly connected to the connecting barrel, and the connecting barrel is connected to the stirring plate through a torsion spring. One end of the connecting rod is threadedly connected to the connecting barrel, and the other end of the connecting rod is threadedly connected to the filter plate. The filter plate is rotatably installed in the feed barrel, and the filter plate is connected to the slide plate through a buffer spring. The slide plate is slidably installed on the inner wall of the feed barrel, and an airbag is provided at one end of the stirring plate away from the connecting barrel, and the feed barrel is slidably connected to the anti-blocking unit.

[0014] Furthermore, the breaking unit also includes a straight rod, a magnetic block, a push rod, a traction rope, a reset spring and an extrusion plate, one end of the straight rod is fixedly connected to the filter plate, and the other end of the straight rod is fixedly connected to the magnetic block. In the vertical direction, two adjacent stirring plates are connected by a push rod, and the extrusion plate is connected to the connecting rod by a traction rope, and the traction rope is slidably connected to the connecting tube, one end of the reset spring is fixedly connected to the extrusion plate, and the other end is fixedly installed on the inner wall of the stirring plate, and the extrusion plate is slidably installed inside the stirring plate.

[0015] When the material is put into the feed barrel, the control console controls the rotation motor to start, driving the connecting barrel to rotate, driving the stirring plate to rotate, on the one hand, driving the connecting rod to rotate upward, and under the action of the restoring force of the reset spring itself, pushing the extrusion plate to move to the right, so that the gas inside the stirring plate enters the air bag, pushing the falling material to hit the inside of the feed barrel to disrupt the material distribution, while increasing the contact area with the material inside the feed barrel to avoid material adhesion, improve the uniformity of the material, avoid uneven heating caused by uneven entry into the screw barrel, and affect the quality of the finished product. On the other hand, under the action of the connecting rod, the filter plate rotates upward to compress the buffer spring. When the magnetic block on the straight rod is close to the stirring plate, the magnetic block pushes the magnet, so that the stirring plate compresses the torsion spring and rotates. Under the action of the push rod, other stirring plates are driven to rotate synchronously, and the materials in the feeding barrel are further broken up to improve the uniformity of the materials. During the reversal of the rotating motor, the filter plate is driven to move downward under the action of the self-restoring force of the buffer spring on the slide plate. At this time, the connecting rod moves downward synchronously, and the compression reset spring of the extrusion plate is pulled to reset under the action of the traction rope, thereby changing the contact area between the stirring plate and the material again, increasing the mixing uniformity of the materials, and pushing the round rod upward during the upward movement of the filter plate.

[0016] Furthermore, the stirring plate is initially at an angle of 30 degrees to the horizontal axis, and a magnet is disposed at the end of one end surface of the stirring plate close to the filter plate.

[0017] When the magnetic block moves upward and approaches the stirring plate, the magnet is pushed to drive the stirring plate to rotate due to the effect of like charges repelling each other, so that the stirring plate can rotate while revolving, thereby increasing the uniformity of material mixing.

[0018] Furthermore, the anti-blocking unit includes a round rod, an air collecting box, a movable plate, an air inlet pipe, an air outlet pipe and a heat conduction pipe. One end of the round rod is slidably connected to the feed barrel, and the other end of the round rod is fixedly connected to the movable plate. The air collecting box is conductively connected to the heat conduction pipe through the air inlet pipe, and the movable plate is slidably installed inside the air collecting box, the air inlet pipe is conductively connected to the heat conduction pipe, one end of the air outlet pipe is conductively connected to the air collecting box, and the other end is conductively connected to the heat conduction pipe, a one-way valve is provided inside the air inlet pipe, and a one-way valve is provided inside the air outlet pipe, one end of the heat conduction pipe is conductively connected to the discharge port of the screw barrel, and the other end is conductively connected to the bottom of the feed barrel, an electric swing plate is provided in the heat conduction pipe located at the bottom of the feed barrel for adjusting the outlet direction, the movable plate is fixedly connected to the detection unit, and the movable plate is connected to the inner wall of the air collecting box through a spring.

[0019] When the filter plate moves upward, it pushes the round rod to move upward, driving the movable plate to move upward, thereby sucking the hot gas in the heat conduction pipe into the lower part of the gas collecting box from the air inlet pipe. When the filter plate moves downward, the filter plate releases the thrust on the round rod, and the spring's own restoring force drives the movable plate to move downward to squeeze the internal hot air out from the air outlet pipe, thereby blowing up the material accumulated on the filter plate and bringing it into contact with the stirring plate again to break it up, avoiding material accumulation and further improving the mixing uniformity of the material. At the same time, the hot air preheats the raw materials, avoiding the problem of uneven heating in the screw barrel and improving the quality of the product.

[0020] Furthermore, the diameter of the air inlet pipe is greater than the diameter of the air outlet pipe.

[0021] In order to make the excess hot air in the screw barrel be ejected from the air guide pipe at high speed and high pressure, it is avoided that the material accumulated on the filter plate cannot be effectively blown up due to insufficient air pressure, thereby affecting the uniformity of material mixing.

[0022] Furthermore, the detection unit includes a bent rod, a rack, a gear, a telescopic probe and a fixed ring, the bent rod is fixedly connected to the movable plate, the rack is fixedly connected to the bent rod, the rack is meshingly connected to the gear, the gear is fixedly mounted on the outer surface of the fixed ring, the fixed end of the telescopic probe is fixedly mounted on the inner wall of the fixed ring, the fixed ring is rotatably mounted on the end of the barrel, and the telescopic probes are coaxially arranged in multiple groups, and each adjacent group of telescopic probes are arranged in sequence with a deviation of 5-15°.

[0023] During the up and down movement of the movable plate, the upper and lower racks are driven to move under the transmission action of the bending rod, so that the gear drives the fixed ring to rotate. During the rotation of the fixed ring, the telescopic probe detects the surface smoothness of the plastic tube produced from the extrusion die head. If there are depressions or protrusions on the surface of the plastic tube, it means that the screw speed at this time does not match the extrusion speed. At this time, the telescopic probe is extended or shortened. When the set length value is changed, the console senses the change in the length of the telescopic probe and triggers an alarm to remind the staff to adjust the screw speed to ensure consistent speed, thereby improving the production quality of the product.

[0024] Furthermore, the tooth ratio of the rack to the gear is 10:1-15:1.

[0025] In order to facilitate the small range movement of the rack to drive the gear to rotate at least one circle, the surface of the plastic pipe can be fully inspected, the integrity of the inspection can be improved, and missed inspections can be avoided.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. When the material is put into the feed barrel, the control console controls the rotation motor to start, drives the connecting barrel to rotate, drives the stirring plate to rotate, and drives the connecting rod to rotate upward. Under the action of the restoring force of the return spring, the extrusion plate is pushed to move rightward, so that the gas inside the stirring plate enters the airbag, and the falling material is pushed to hit the inside of the feed barrel to disrupt the material distribution. At the same time, the contact area with the material inside the feed barrel is increased to avoid material adhesion, improve the uniformity of the material, avoid uneven heating caused by uneven entry into the screw barrel, and affect the quality of the finished product. On the other hand, under the action of the connecting rod, the filter plate is rotated upward to compress the buffer spring. When the magnetic block on the straight rod is close to the stirring plate, the magnetic block pushes the magnet, so that the stirring plate compresses the torsion spring and rotates. Under the action of the push rod, other stirring plates are driven to rotate synchronously, and the material in the feed barrel is further scattered to improve the uniformity of the material. In the reversal process of the rotating motor, under the action of the self-restoring force of the buffer spring on the slide plate, the filter plate is driven to move downward. At this time, the connecting rod moves downward synchronously, and the extrusion plate is pulled to compress the return spring under the action of the traction rope to reset, and the contact area between the stirring plate and the material is changed again, and the mixing uniformity of the material is increased.

[0028] 2. The present invention drives the movable plate to move upward when the filter plate moves upward and pushes the round rod to move upward, thereby sucking the hot gas in the heat conduction pipe into the lower part of the gas collecting box from the air inlet pipe. When the filter plate moves downward, the filter plate releases the thrust on the round rod, and drives the movable plate to move downward under the action of the spring's own restoring force to squeeze the internal hot air out from the air outlet pipe, thereby blowing up the material accumulated on the filter plate and bringing it into contact with the stirring plate again to break it up, avoiding material accumulation and further improving the mixing uniformity of the material. At the same time, the hot air preheats the raw materials, avoiding the problem of uneven heating in the screw barrel and improving the quality of the product.

[0029] 3. The present invention drives the upper and lower racks to move under the transmission action of the bending rod during the up and down movement of the movable plate, so that the gear drives the fixed ring to rotate. During the rotation of the fixed ring, the telescopic probe detects the surface smoothness of the plastic tube produced from the extrusion die head. If there are depressions or protrusions on the surface of the plastic tube, it means that the screw speed at this time does not match the extrusion speed. At this time, when the telescopic probe is extended or shortened and the set length value is changed, the control console senses the change in the length of the telescopic probe and triggers an alarm to remind the staff to adjust the screw speed to ensure the consistency of the speed, thereby improving the production quality of the product.

The fixed end of the rotating motor 32 is fixedly installed above the feed barrel 31, and the output end of the rotating motor 32 is fixedly connected to the connecting barrel 33. The connecting barrel 33 is connected to the stirring plate 34 through a torsion spring. One end of the connecting rod 35 is threadedly connected to the connecting barrel 33, and the other end of the connecting rod 35 is threadedly connected to the filter plate 36. The filter plate 36 is rotatably installed in the feed barrel 31, and the filter plate 36 is connected to the slide plate 38 through a buffer spring 37. The slide plate 38 is slidably installed on the inner wall of the feed barrel 31. An air bag is provided at one end of the stirring plate 34 away from the connecting barrel 33, and the feed barrel 31 is slidably connected to the anti-blocking unit 4.

[0050] like Figure 8 , 10 As shown, the breaking unit 3 also includes a straight rod 39, a magnetic block 310, a push rod 311, a traction rope 312, a reset spring 313 and an extrusion plate 314. One end of the straight rod 39 is fixedly connected to the filter plate 36, and the other end of the straight rod 39 is fixedly connected to the magnetic block 310. In the vertical direction, two adjacent stirring plates 34 are connected by the push rod 311, and the extrusion plate 314 is connected to the connecting rod 35 by the traction rope 312. The traction rope 312 is slidably connected to the connecting tube 33.

The extrusion plate 314 is slidably installed inside the stirring plate 34.

[0051] When the material is put into the feed barrel 31, the control console 12 controls the rotating motor 32 to start, drive the connecting barrel 33 to rotate, drive the stirring plate 34 to rotate, and on the one hand drive the connecting rod 35 to rotate upward, and under the action of the restoring force of the return spring 313 itself, push the extrusion plate 314 to move to the right, so that the internal gas of the stirring plate 34 enters the air bag, and pushes the falling material to hit the inside of the feed barrel 31 to disrupt the material distribution, while increasing the contact area with the material inside the feed barrel 31 to avoid material adhesion, improve the uniformity of the material, avoid uneven heating caused by uneven entry into the screw barrel 22, and affect the quality of the finished product. On the other hand, under the action of the connecting rod 35, the filter plate 36 rotates upward to compress the buffer spring 37. When the straight rod 39 When the magnetic block 310 on the stirring plate 34 is close to the magnetic block 310, the magnetic block 310 pushes the magnet, so that the stirring plate 34 compresses the torsion spring and rotates. Under the action of the push rod 311, the other stirring plates 34 are driven to rotate synchronously, and the materials in the feeding barrel 31 are further dispersed to improve the uniformity of the materials. During the reversal of the rotating motor 32, the filter plate 36 is driven to move downward under the action of the self-restoring force of the buffer spring 37 on the slide plate 38. At this time, the connecting rod 35 moves downward synchronously, and under the action of the traction rope 312, the extrusion plate 314 is pulled to compress the reset spring 313 to reset, thereby changing the contact area between the stirring plate 34 and the material again, increasing the mixing uniformity of the materials. During the upward movement of the filter plate 36, the round rod 41 is pushed to move upward.

[0052] like Fig.10 As shown, the stirring plate 34 is initially at an angle of 30 degrees to the horizontal axis, and a magnet is provided at the end of one end surface of the stirring plate 34 close to the filter plate 36 .

[0053] When the magnetic block 310 moves upward and approaches the stirring plate 34, the stirring plate 34 is driven to rotate by the magnet due to the repulsion of like charges, so that the stirring plate 34 revolves and rotates at the same time, thereby increasing the uniformity of material mixing.

[0054] like Fig.10 As shown, the anti-blocking unit 4 includes a round rod 41, an air collecting box 42, a movable plate 43, an air inlet pipe 44, an air outlet pipe 45 and a heat conducting pipe 46. One end of the round rod 41 is slidably connected to the feed barrel 31, and the other end of the round rod 41 is fixedly connected to the movable plate 43. The air collecting box 42 is connected to the heat conducting pipe 46 through the air inlet pipe 44. The movable plate 43 is slidably installed inside the air collecting box 42. The air inlet pipe 44 is connected to the heat conducting pipe 46. One end of the air outlet pipe 45 is connected to the air collecting box 42. The air inlet pipe 44 is provided with a one-way valve inside, the air outlet pipe 45 is provided with a one-way valve inside, one end of the heat-conducting pipe 46 is conductively connected to the discharge port of the screw barrel 22, and the other end is conductively connected to the bottom of the feed barrel 31, and an electric swing plate is provided in the heat-conducting pipe 46 at the bottom of the feed barrel 31 for adjusting the outlet direction of the gas, the movable plate 43 is fixedly connected to the detection unit 5, and the movable plate 43 is connected to the inner wall of the air collecting box 42 through a spring.

[0055] When the filter plate 36 moves upward, it pushes the round rod 41 to move upward, and drives the movable plate 43 to move upward, so that the hot gas in the heat conduction pipe 46 is sucked into the lower part of the gas collecting box 42 from the air inlet pipe 44. When the filter plate 36 moves downward, the filter plate 36 releases the thrust on the round rod 41, and drives the movable plate 43 to move downward under the action of the spring's own restoring force to squeeze the internal hot air out from the air outlet pipe 45, so that the material accumulated on the filter plate 36 is blown up and contacts the stirring plate 34 again to break it up, avoiding material accumulation and further improving the mixing uniformity of the material. At the same time, the hot air preheats the raw materials, avoiding the problem of uneven heating in the screw barrel 22, thereby improving the quality of the product.

[0056] like Fig.10 As shown, the diameter of the air inlet pipe 44 is greater than the diameter of the air outlet pipe 45 .

[0057] In order to make the excess hot air in the screw barrel 22 be ejected from the air guide pipe at high speed and high pressure, it is avoided that the material accumulated on the filter plate 36 cannot be effectively blown up due to insufficient air pressure, thereby affecting the uniformity of material mixing.

[0058] like Figure 6 As shown, the detection unit 5 includes a bent rod 51, a rack 52, a gear 53, a telescopic probe 54 and a fixed ring 55. The bent rod 51 is fixedly connected to the movable plate 43, the rack 52 is fixedly connected to the bent rod 51, the rack 52 is meshingly connected to the gear 53, the gear 53 is fixedly mounted on the outer surface of the fixed ring 55, the fixed end of the telescopic probe 54 is fixedly mounted on the inner wall of the fixed ring 55, the fixed ring 55 is rotatably mounted on the end of the screw barrel 22, and the telescopic probes 54 have multiple groups of coaxial arrangements, and each adjacent group of telescopic probes 54 are arranged in sequence with a deviation of 5-15°.

[0059] During the up and down movement of the movable plate 43, the upper and lower racks 52 are driven to move under the transmission action of the bent rod 51, so that the gear 53 drives the fixed ring 55 to rotate. During the rotation of the fixed ring 55, the telescopic probe 54 detects the surface smoothness of the plastic tube produced from the extrusion die head. If there are depressions or protrusions on the surface of the plastic tube, it means that the rotation speed of the screw 23 at this time does not match the extrusion speed. At this time, the telescopic probe 54 is extended or shortened. When the set length value is changed, the control console 12 senses the change in the length of the telescopic probe 54, triggers an alarm, and reminds the staff to adjust the rotation speed of the screw 23 to ensure the consistency of the rotation speed, thereby improving the production quality of the product.

[0060] like Figure 6 As shown, the gear ratio between the rack 52 and the gear 53 is 10:1-15:1.

[0061] In order to facilitate the small range movement of the rack 52 to drive the gear 53 to rotate at least one circle, the surface of the plastic pipe can be fully inspected, the integrity of the inspection can be improved, and missed inspections can be avoided.

[0062] Working principle of the present invention:

[0063] When the material is put into the feed barrel 31, the control console 12 controls the rotating motor 32 to start, drive the connecting barrel 33 to rotate, drive the stirring plate 34 to rotate, and on the one hand drive the connecting rod 35 to rotate upward, and under the action of the restoring force of the return spring 313 itself, push the extrusion plate 314 to move to the right, so that the internal gas of the stirring plate 34 enters the air bag, and pushes the falling material to hit the inside of the feed barrel 31 to disrupt the material distribution, while increasing the contact area with the material inside the feed barrel 31 to avoid material adhesion, improve the uniformity of the material, avoid uneven heating caused by uneven entry into the screw barrel 22, and affect the quality of the finished product. On the other hand, under the action of the connecting rod 35, the filter plate 36 rotates upward to compress the buffer spring 37. When the straight rod 39 When the magnetic block 310 on the stirring plate 34 is close to the magnetic block 310, the magnetic block 310 pushes the magnet, so that the stirring plate 34 compresses the torsion spring and rotates. Under the action of the push rod 311, the other stirring plates 34 are driven to rotate synchronously, and the materials in the feeding barrel 31 are further dispersed to improve the uniformity of the materials. During the reversal of the rotating motor 32, the filter plate 36 is driven to move downward under the action of the self-restoring force of the buffer spring 37 on the slide plate 38. At this time, the connecting rod 35 moves downward synchronously, and under the action of the traction rope 312, the extrusion plate 314 is pulled to compress the reset spring 313 to reset, thereby changing the contact area between the stirring plate 34 and the material again, increasing the mixing uniformity of the materials. During the upward movement of the filter plate 36, the round rod 41 is pushed to move upward.

[0064] When the filter plate 36 moves upward, it pushes the round rod 41 to move upward, and drives the movable plate 43 to move upward, so that the hot gas in the heat conduction pipe 46 is sucked into the lower part of the gas collecting box 42 from the air inlet pipe 44. When the filter plate 36 moves downward, the filter plate 36 releases the thrust on the round rod 41, and drives the movable plate 43 to move downward under the action of the spring's own restoring force to squeeze the internal hot air out from the air outlet pipe 45, so that the material accumulated on the filter plate 36 is blown up and contacts the stirring plate 34 again to break it up, avoiding material accumulation and further improving the mixing uniformity of the material. At the same time, the hot air preheats the raw materials, avoiding the problem of uneven heating in the screw barrel 22, thereby improving the quality of the product.

[0065] During the up and down movement of the movable plate 43, the upper and lower racks 52 are driven to move under the transmission action of the bent rod 51, so that the gear 53 drives the fixed ring 55 to rotate. During the rotation of the fixed ring 55, the telescopic probe 54 detects the surface smoothness of the plastic tube produced from the extrusion die head. If there are depressions or protrusions on the surface of the plastic tube, it means that the rotation speed of the screw 23 at this time does not match the extrusion speed. At this time, the telescopic probe 54 is extended or shortened. When the set length value is changed, the control console 12 senses the change in the length of the telescopic probe 54, triggers an alarm, and reminds the staff to adjust the rotation speed of the screw 23 to ensure the consistency of the rotation speed, thereby improving the production quality of the product.

[0066] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
