Description

Technical Field

[0001] The invention relates to the technical field of PS plate production, in particular to an anti-blocking PS plate production feeding mechanism. Background Art

[0002] PS sheet is polystyrene sheet, which is a thermoplastic plastic sheet. Polystyrene (PS) has the advantages of light weight, low price, low water absorption, good electrical insulation performance, good transparency, etc. In the production process of PS sheet, the extrusion molding step requires the use of an extruder. During the use of the extruder, the amount of material added will affect the service life of the machine. The extruder is generally fed in a hungry manner. Therefore, the material cannot completely fill the screw groove during the extrusion process, which is conducive to the mixing, plasticization and exhaust of the material. If the material is added too much, the screw groove will be filled with material, affecting exhaust and plasticization. In severe cases, the material may even come out from the exhaust. If there is too little material in the screw groove, then there is too little material above the screw and sufficient material below. In this case, the screw will be warped, resulting in the screw and The friction of the barrel increases, damaging the screw barrel. Too little material will also lead to insufficient shear. Common feeding methods are gravity feeding and forced feeding. Gravity feeding relies on the gravity of the material to flow from the hopper into the feed port of the extruder. This method is simple and low in cost, but the feeding amount is relatively unstable. It is affected by factors such as the particle size, shape, fluidity and the height of the material in the hopper. There will be too much or too little feeding. Forced feeding uses a screw feeder to force the material into the extruder. When the moisture of the material increases, the material may stick together, affecting its fluidity in the feeder, which will cause the screw to run idle or the material to not be pushed smoothly, resulting in too little feeding. When the material is too dry and too fluid, overfeeding may occur. Summary of the Invention

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive of other embodiments.

[0032] Example 1

[0033] Reference Figure 1 - Figure 6 , which is the first embodiment of the present invention, provides an anti-clogging PS sheet production feeding mechanism, the anti-clogging PS sheet production feeding mechanism includes a production component 100, including a frame 101, an extrusion mechanism 102 is provided on the frame 101, a feeding pipe 103 is fixed on the top of the extrusion mechanism 102, and a storage bin 104 is fixed on the top of the feeding pipe 103.

[0034] The extrusion mechanism 102 includes an extrusion screw and a drive motor. A heating device is provided on the outside of the extrusion mechanism 102. The granular material is added into the storage bin 104 and transported to the extrusion mechanism 102 through the feed pipe 103. Under the push of the screw, the molten material is extruded through the die of the extruder to form a sheet blank with a certain shape and size. After that, after subsequent processes such as calendering, cooling, pulling, and cutting, the PS sheet product is finally obtained.

[0035] The auxiliary component 200 is arranged on the feed pipe 103 and includes a quantitative part 201. The quantitative part 201 includes a collecting frame 201a. The collecting frame 201a is fixed to one side of the feed pipe 103. A card slot 103-1 is provided on one side of the feed pipe 103. A receiving plate 201b is provided in the card slot 103-1. A feed trough 103-2 is provided on one side of the feed pipe 103. A baffle plate 201c is rotatably connected to the feed trough 103-2 through a rotating shaft. An intercepting plate 201d is fixed to one side of the receiving plate 201b. A rotating column 201e is inserted into the receiving plate 201b. A torsion spring 201f is sleeved on the outside of the rotating column 201e. The two ends of the torsion spring 201f are respectively fixed to the rotating column 201e and the inner wall of the receiving plate 201b.

[0036] The collecting frame 201a is semicircular, and there are two intercepting plates 201d, which are fixed at both ends of one side of the receiving plate 201b. The rotating column 201e is rotatably connected to the feed pipe 103 through a bearing, and the rotating column 201e is connected to the receiving plate 201b through a torsion spring 201f, so that when the rotating column 201e rotates, it can drive the receiving plate 201b to rotate.

[0037] The baffle plate 201c is used to block the feed trough 103-2 to prevent the material inside the collection frame 201a from flowing into the feed pipe 103. A feeding port is provided on the top of the collection frame 201a. During operation, some material can be added to the collection frame 201a in advance.

[0038] When the amount of material discharged into the feed pipe 103 is normal, the receiving plate 201b and the baffle plate 201c are both in a vertical state. When the amount of material discharged into the feed pipe 103 is too much, the receiving plate 201b will tilt toward the inside of the feed pipe 103, and intercept the material falling from the inside of the feed pipe 103, and transport the intercepted material to the collection frame 201a, so as to reduce the material entering the extrusion mechanism 102, thereby avoiding the situation where excessive amount of material will affect exhaust and plasticization.

[0039] When the amount of falling material is too small, the baffle plate 201c will rotate and open upward inside the feed pipe 103, thereby releasing the interception of the material inside the collection frame 201a. At this time, the material inside the collection frame 201a will flow into the feed pipe 103, thereby increasing the material entering the extrusion mechanism 102, thereby avoiding the situation where the friction between the screw and the barrel is aggravated and the screw and barrel are damaged. When the amount of material is too small, the inclination angle of the baffle plate 201c will be adaptively increased, thereby speeding up the material entering the feed pipe 103, and thus quickly replenishing the missing material.

[0040] The intercepting plate 201d is used to intercept the material on the top of the receiving plate 201b to prevent the material intercepted by the receiving plate 201b from falling into the feed pipe 103 again.

[0041] The auxiliary component 200 also includes a trigger 202, which includes a guide plate 202a. A positioning column 202b is fixed in the guide plate 202a. One end of the positioning column 202b passes through the outside of the feed pipe 103 and is rotatably connected to the feed pipe 103 through a bearing. A stabilizing column 202c is fixed to the bottom of the guide plate 202a. A first spring 202d is sleeved on the outside of the stabilizing column 202c. The two ends of the first spring 202d are respectively connected to the guide plate 202a. It is fixed to the inner wall of the feed pipe 103, a material distribution trough 202a-1 is provided on the guide plate 202a, a rotating rod 202e is fixed to the outside of the positioning column 202b, a connecting frame 202f is fixed to the end of the rotating rod 202e, a connecting shaft 202g is fixed to the connecting frame 202f, a rotating rod 202h is fixed to the outside of the rotating column 201e, a sliding groove 202h-1 is provided on the rotating rod 202h, and the connecting shaft 202g slides in the sliding groove 202h-1.

[0042] The positioning column 202b is used to support and position the guide plate 202a, and the stabilizing column 202c is used to position the first spring 202d to prevent the first spring 202d from deforming when compressed.

[0043] When the material is discharged, it will fall on the top of the guide plate 202a and apply downward pressure to the guide plate 202a. At this time, the first spring 202d applies an upward thrust to the guide plate 202a. When the amount of material falling is just right, the guide plate 202a will remain in a tilted state. As the material continues to fall, the guide plate 202a will continue to remain in the current state.

[0044] When the amount of material falling is too much, the pressure on the guide plate 202a will increase, and it will overcome the elastic force of the first spring 202d and rotate downward, driving the positioning column 202b to rotate, so that the positioning column 202b drives the rotating rod 202e to rotate, and the rotating rod 202e drives the rotating rod 202h to rotate downward through the cooperation of the connecting shaft 202g and the slide groove 202h-1, so that the rotating rod 202h can drive the rotating column 201e to rotate, and then the rotating column 201e can drive the receiving plate 201b to tilt toward the inside of the feeding pipe 103, so as to intercept excess material.

[0045] When the amount of material discharged is too small, the pressure on the guide plate 202a is reduced, and the elastic force generated by the first spring 202d will push the guide plate 202a to rotate upward. The guide plate 202a drives the rotating rod 202e to rotate through the positioning column 202b, and the rotating rod 202e drives the rotating rod 202h to rotate upward through the cooperation of the connecting shaft 202g and the slide groove 202h-1. The rotating rod 202h drives the receiving plate 201b to rotate into the collection frame 201a through the rotating column 201e, and pushes the baffle plate 201c to rotate into the feed pipe 103 through the receiving plate 201b, so that the material inside the collection frame 201a can flow into the feed pipe 103, thereby increasing the amount of material discharged.

[0046] In the future, the material distribution trough 202a-1 is set to evenly distribute the material falling on the top of the guide plate 202a on the top of the guide plate 202a, so that the receiving plate 201b can intercept a specified amount of material when intercepting the material, without intercepting too much or too little material.

[0047] Example 2

[0048] Reference Figure 4 - Figure 10 , which is the second embodiment of the present invention, and is based on the previous embodiment.

[0049] Specifically, the auxiliary component 200 also includes a pushing member 203, which includes a push column 203a, which is fixed to one side of the material blocking plate 201c, and a stabilizing sleeve 203b is provided on the outer side of the push column 203a, which is fixed to the inner wall of the collection frame 201a through a connecting column, and a mounting plate 203c is fixed to the outer side of the push column 203a, and a second spring 203d is fixed to one side of the mounting plate 203c, and the other end of the second spring 203d is fixed to the stabilizing sleeve 203b.

[0050] The push pin 203a is arc-shaped, and the stabilizing sleeve 203b is used to support and position the push pin 203a. When the receiving plate 201b rotates into the collecting frame 201a, the push pin 203a will be pushed to move, so that the blocking plate 201c can be pushed to open by the push pin 203a.

[0051] When the receiving plate 201b is reset, the second spring 203d applies a thrust to the mounting plate 203c, and the mounting plate 203c drives the push column 203a to move, so that the push column 203a can drive the blocking plate 201c to reset and close, and intercept the material inside the collecting frame 201a again.

[0052] The elastic force of the second spring 203d is smaller than the elastic force of the torsion spring 201f, and the elastic force of the second spring 203d is sufficient to close the baffle plate 201c. The elastic force of the first spring 202d is larger than the elastic force of the torsion spring 201f and the second spring 203d.

[0053] Specifically, the auxiliary component 200 also includes an extension piece 204, which includes an extension plate 204a. A positioning plate 204b is fixed to one side of the extension plate 204a. A stabilizing rod 204c is fixed inside the positioning plate 204b. One end of the stabilizing rod 204c is rotatably connected to the receiving plate 201b.

[0054] The extension plate 204a is triangular in shape, and the height of the positioning plate 204b is flush with the interception plate 201d, and is used to intercept materials on the top of the extension plate 204a. There are two extension plates 204a and two positioning plates 204b.

[0055] When the receiving plate 201b rotates to a certain angle and cannot rotate anymore, and the guide plate 202a continues to rotate downward, the stabilizing bar 204c will drive the extension plate 204a to rotate toward the side of the receiving plate 201b, thereby increasing the width of the receiving plate 201b and further increasing the amount of material intercepted by the receiving plate 201b.

[0056] Specifically, a swing rod 204d is fixed to the outside of the stabilizing rod 204c, a chamber 201b-1 is opened in the receiving plate 201b, the swing rod 204d is movably connected to the chamber 201b-1, a moving rod 204e is provided in the chamber 201b-1, a positioning shaft 204f is fixed to the end of the moving rod 204e, a positioning groove 204d-1 is opened on the swing rod 204d, and the positioning shaft 204f slides in the positioning groove 204d-1.

[0057] The moving rod 204e is connected to the swing rod 204d through the cooperation of the positioning shaft 204f and the positioning slot 204d-1. When the moving rod 204e moves upward, it can drive the swing rod 204d to rotate, thereby allowing the swing rod 204d to drive the stabilizing rod 204c to rotate.

[0058] Specifically, a fixed column 204g is fixed to the bottom of the moving rod 204e, a force block 204h is fixed to the bottom end of the fixed column 204g, and an extrusion block 204i is fixed to the outside of the rotating column 201e.

[0059] When the receiving plate 201b cannot continue to rotate after rotating to the specified angle, and the guide plate 202a continues to rotate downward, the rotating column 201e will apply a torsional force to the torsion spring 201f, and drive the extrusion block 204i to squeeze the inclined surface of the force-bearing block 204h, thereby pushing the force-bearing block 204h to move, and driving the fixed column 204g to move through the force-bearing block 204h, and then the fixed column 204g can drive the moving rod 204e to move upward.

[0060] Specifically, the auxiliary component 200 also includes a blanking part 205, which includes a rotating roller 205a, which is rotatably connected to the feed pipe 103 through a rotating shaft, and a material plate 205b is fixed to the outside of the rotating roller 205a. There are multiple material plates 205b, which are fixed in a ring shape to the outside of the rotating roller 205a. A motor 205c is fixed to one side of the feed pipe 103, and the output shaft of the motor 205c is fixed to the rotating roller 205a.

[0061] The motor 205c is used to drive the rotating roller 205a to rotate. When the rotating roller 205a is rotating, the material inside the storage bin 104 can be transported downward through the cooperation of the material plate 205b. By setting up multiple material plates 205b, the uniformity of the material falling can be ensured.

[0062] Example 3

[0063] Reference Figure 1 - Figure 10 , which is the third embodiment of the present invention, is based on the first two embodiments.

[0064] Specifically, a positioning rod 204j is fixed to the inner wall of the chamber 201b-1, and the positioning rod 204j is movably connected to the moving rod 204e. A third spring 204k is fixed to the top of the moving rod 204e, and the top end of the third spring 204k is fixed to the inner wall of the chamber 201b-1.

[0065] The positioning rod 204j is used to position the moving rod 204e to prevent it from deflecting during movement. The third spring 204k applies a thrust to the moving rod 204e so that it can be reset after movement.

[0066] Specifically, a limiting block 201g is fixed on one side of the feed trough 103-2, and one side of the limiting block 201g is inclined, which is used to limit the rotation angle of the butting plate 201b.

[0067] When the receiving plate 201b rotates to a certain angle, it will contact the limit block 201g, so that its rotation angle can be limited by the limit block 201g to avoid the situation where its rotation angle is too large and the material intercepted at the top cannot be guided into the collection frame 201a.

[0068] Specifically, the bottom of the collecting frame 201a is inclined. The inclined bottom allows the material to flow into the feed pipe 103 by gravity.

[0069] Specifically, one side of the load-bearing block 204h is inclined.

[0070] During use, after the material is added to the storage bin 104, the motor 205c is started to drive the rotating roller 205a to rotate. When the rotating roller 205a is rotating, the material inside the storage bin 104 can be transported downward through the cooperation of the material plate 205b. The discharged material will fall on the top of the guide plate 202a and exert downward pressure on the guide plate 202a. At this time, the first spring 202d exerts an upward thrust on the guide plate 202a. When the amount of material falling is just right, the guide plate 202a will remain in a tilted state. As the material continues to fall, the guide plate 202a will continue to remain in the current state.

[0071] When the amount of material falling is too much, the pressure on the guide plate 202a will increase, and it will overcome the elastic force of the first spring 202d and rotate downward, driving the positioning column 202b to rotate, so that the positioning column 202b drives the rotating rod 202e to rotate, and the rotating rod 202e drives the rotating rod 202h to rotate downward through the cooperation of the connecting shaft 202g and the slide groove 202h-1, so that the rotating rod 202h can drive the rotating column 201e to rotate, and then the rotating column 201e can drive the receiving plate 201b to tilt toward the inside of the feed pipe 103, and intercept the material falling from the inside of the feed pipe 103, and transport the intercepted material to the collecting frame 201a, so as to reduce the material entering the extrusion mechanism 102, thereby avoiding the situation where too much material will affect the exhaust and plasticization.

[0072] When the receiving plate 201b cannot continue to rotate at the specified angle and the guide plate 202a continues to rotate downward, the rotating column 201e will apply a torsional force to the torsion spring 201f, and drive the extrusion block 204i to squeeze the inclined surface of the force-bearing block 204h, thereby pushing the force-bearing block 204h to move, and through the force-bearing block 204h, the fixed column 204g can move, and then the fixed column 204g can drive the moving rod 204e to move upward. When the moving rod 204e moves upward, it can drive the swinging rod 204d to rotate, so that the swinging rod 204d can drive the stabilizing rod 204c to rotate, and the stabilizing rod 204c will drive the extension plate 204a to rotate toward the side of the receiving plate 201b, thereby increasing the width of the receiving plate 201b, and thereby increasing the number of materials intercepted by the receiving plate 201b.

[0073] When the amount of material discharged is too small, the pressure on the guide plate 202a is reduced, and the elastic force generated by the first spring 202d will push the guide plate 202a to rotate upward. The guide plate 202a drives the rotating rod 202e to rotate through the positioning column 202b. The rotating rod 202e drives the rotating rod 202h to rotate upward through the cooperation of the connecting shaft 202g and the slide groove 202h-1. The rotating rod 202h drives the receiving plate 201b to rotate into the collecting frame 201a through the rotating column 201e. At this time, the receiving plate 201b pushes the column 203a. Move, and push the baffle plate 201c to open through the push column 203a, so as to release the interception of the material inside the collection frame 201a. At this time, the material inside the collection frame 201a will flow into the feed pipe 103, thereby increasing the material entering the extrusion mechanism 102, thereby avoiding the situation where the friction between the screw and the barrel is aggravated and the screw and barrel are damaged. When the amount of material is small or large, the inclination angle of the baffle plate 201c will be adaptively increased, thereby speeding up the material entering the feed pipe 103, and thus quickly replenishing the missing material.

[0074] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
