Technical Field
[0001] The utility model relates to the technical field of feeding devices, in particular to an automatic feeding device for an upward-blowing film-blowing wire-drawing machine. Background Art
[0002] The upward blowing film blowing wire drawing machine is a plastic processing equipment used to make plastic films and filaments. Film blowing is to heat and melt plastic particles and then blow them into films. Wire drawing is to heat, extrude, split and stretch plastic particles to form flat wires, which are then rolled up for weaving on a circular loom. It combines film blowing technology and wire drawing technology to produce plastic products of different specifications and uses.
[0003] The feeding device of the blown film wire drawing machine usually puts the raw materials into the feed barrel, and then transports them to the blown film wire drawing machine for manufacturing via a conveyor. However, in the actual production process, it is necessary to produce plastic products of different specifications and varieties, and it is necessary to replace the remaining raw materials in the feed barrel. The blown film wire drawing machine in the prior art is difficult to quickly unload the remaining raw materials in the feed barrel, and it is not convenient to replace the raw materials, which affects the production efficiency of the blown film wire drawing machine. Utility Model Content
[0004] In order to solve the above problems, the utility model provides an automatic feeding device for an upward blowing type film blowing wire drawing machine.
[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: an automatic feeding device for an upward blowing film blowing wire drawing machine, comprising a base plate and a screw conveyor fixed to the upper surface of the base plate, the top of the screw conveyor is fixed and connected to a feed pipe, a mounting seat is fixedly provided on the feed pipe, a limiting groove is provided at the intersection between the upper surface of the mounting seat and the side wall of the mounting seat, a support rod is fixed on the upper surface of the base plate, a connecting block is rotatably connected to the upper end of the support rod, a feeding assembly is installed on the connecting block, the feeding assembly comprises a feeding barrel fixed to the side wall of the connecting block, a feeding pipe fixed and connected to the bottom of the feeding barrel, and a valve arranged on the feeding pipe, the feeding pipe cooperates with the limiting groove, a fixing groove is provided on the inner wall of the limiting groove, a fixing block matching the fixing groove is fixed on the side wall of the feeding pipe, and a limiting assembly for limiting the fixing block is installed on the mounting seat.
[0006] By adopting the above technical scheme, the raw materials are put into the feed barrel, and the feeding amount is controlled by the valve. The raw materials enter the screw conveyor through the feed pipe and are transported to the film blowing and drawing machine for manufacturing. When the raw materials in the feed barrel need to be replaced, the staff releases the limiting effect of the limiting assembly on the fixed block, thereby rotating the feed barrel along the axis of the support rod to separate from the mounting seat, and then opening the valve to take out the remaining raw materials, which is convenient for rapid unloading of the raw materials in the feed barrel, thereby facilitating the replacement of raw materials and improving the production efficiency of the film blowing and drawing machine.
[0007] Furthermore, a plug-in groove is provided on the side wall of the fixing block away from the discharge pipe, and the limiting assembly includes a pin which is penetrated and slidably connected to the side wall of the mounting seat, and an operating block fixed to the end of the pin away from the fixing block, and the pin is plugged into the plug-in groove.
[0008] By adopting the above technical solution, the pin is inserted into the mounting seat and the plug-in slot, which plays a limiting role on the fixed block and the discharge pipe. When the raw materials need to be replaced, the staff only needs to pull the pin out of the plug-in slot through the operating block, thereby releasing the limiting effect on the fixed block and facilitating the rotation of the feed barrel for unloading.
[0009] Furthermore, a mounting groove is provided on the side wall of the mounting seat, a spring sleeved on the latch is provided in the mounting groove, one end of the spring is fixed to the inner wall of the mounting groove, and the other end of the spring is fixed to the side wall of the operating block.
[0010] By adopting the above technical solution, the operating block causes the latch to press against the insertion slot under the elastic force of the spring, thereby reducing the probability of the latch being separated from the insertion slot and causing the discharge pipe and the feed barrel to move.
[0011] Furthermore, the side wall of the latch is provided with an inclined surface for making way for matching with the side wall of the fixing block.
[0012] By adopting the above technical solution, in the process of rotating the discharge pipe into the limit groove, the fixed block cooperates with the inclined surface to squeeze the pin into the mounting seat, eliminating the tedious operation of the staff manually pulling the operating block, and facilitating the rapid limitation of the fixed block.
[0013] Furthermore, a rubber pad is fixed to the inner wall of the limiting groove.
[0014] By adopting the above technical solution, the rubber pad is made of rubber material, which is elastic. The feed tube cooperates with the limiting groove and presses against the rubber pad, thereby reducing the wear between the feed tube and the limiting groove.
[0015] Furthermore, a handle is fixed to the side wall of the feeding barrel.
[0016] By adopting the above technical solution, the setting of the handle provides a fulcrum for the feeding barrel, making it convenient for the staff to pull the feeding barrel to move by the handle.
[0017] Furthermore, a transparent window is provided on the side wall of the feed barrel.
[0018] By adopting the above technical solution and setting the transparent window, the staff can observe the remaining amount of raw materials in the feeding barrel through the transparent window, so as to replenish the raw materials in time.
[0019] Furthermore, the inner wall of the feed barrel is inclined downward toward one side of the discharge pipe.
[0020] By adopting the above technical solution, the inclined feeding barrel allows the raw materials to roll toward the lower feeding tube under the action of gravity, thereby reducing the probability of residual raw materials on the inner wall of the feeding barrel.
[0021] In summary, the utility model has the following beneficial effects:
[0022] 1. In the present application, the raw materials are put into the feed barrel, and the amount of the raw materials is controlled by a valve. The raw materials enter the screw conveyor through the feed pipe and are transported to the film blowing wire drawing machine for manufacturing. When the raw materials in the feed barrel need to be replaced, the staff releases the limiting effect of the limiting component on the fixed block, thereby rotating the feed barrel along the axis of the support rod to separate from the mounting seat, and then opening the valve to take out the remaining raw materials, which is convenient for the rapid unloading of the raw materials in the feed barrel, thereby facilitating the replacement of the raw materials and improving the production efficiency of the film blowing wire drawing machine;
[0023] 2. In this application, the latch is inserted into the mounting seat and the insertion slot, which limits the fixed block and the feeding tube. When the raw material needs to be replaced, the staff only needs to pull the latch out of the insertion slot through the operating block, thereby releasing the limiting effect on the fixed block, making it easier to rotate the feeding tube for unloading;
[0024] 3. In the present application, the operating block causes the latch to press against the insertion slot under the elastic force of the spring, thereby reducing the probability that the latch will be separated from the insertion slot and cause the discharge pipe and the feed barrel to move.

DETAILED DESCRIPTION
[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.
[0030] like Figure 1-3 As shown, an embodiment of the present application discloses an automatic feeding device for an upward-blowing film blowing wire drawing machine, comprising a base plate 1, a screw conveyor 2, a feed pipe 3, a mounting seat 4, a support rod 5, a connecting block 6, a feed discharge assembly 7, a fixing block 8 and a limit assembly 9.
[0031] The bottom plate 1 is a rectangular plate-like structure, and the bottom plate 1 is used to carry the device. The screw conveyor 2 is a screw conveyor 2 commonly used in the prior art and suitable for the present embodiment, and the screw conveyor 2 is fixed on the upper surface of the bottom plate 1. The feed pipe 3 is a vertically arranged circular tubular structure, and the feed pipe 3 is fixed and connected to the top of the screw conveyor 2. The mounting seat 4 is a rectangular parallelepiped structure, and the mounting seat 4 is fixedly sleeved on the feed pipe 3. A limiting groove 41 is provided at the intersection between the upper surface of the mounting seat 4 and the side wall of the mounting seat 4, and a fixing groove 42 is provided on the inner wall of the limiting groove 41, and a mounting groove 43 is provided on the side wall of the mounting seat 4. The support rod 5 is a vertically arranged circular rod-like structure, and the support rod 5 is fixed on the upper surface of the bottom plate 1. The connecting block 6 is a rectangular parallelepiped structure, and the connecting block 6 is rotatably connected to the upper end of the support rod 5.
[0032] The material discharge assembly 7 is installed on the connecting block 6, and the material discharge assembly 7 includes a feed barrel 71, a feed pipe 72 and a valve 73. The feed barrel 71 is a cylindrical structure with an opening at the top, and the feed barrel 71 is fixed on the side wall of the connecting block 6. The feed pipe 72 is a circular tubular structure, and the feed pipe 72 is fixed and connected to the bottom of the feed barrel 71, and the feed pipe 72 cooperates with the limit groove 41. The valve 73 is a valve 73 commonly used in the prior art and suitable for this embodiment, and the valve 73 is arranged on the feed pipe 72. The fixed block 8 is a rectangular parallelepiped structure, and the fixed block 8 is fixed on the side wall of the feed pipe 72, and the fixed block 8 cooperates with the fixed groove 42, and the side wall of the fixed block 8 away from the feed pipe 72 is provided with a plug-in groove 81.
[0033] The limit assembly 9 is installed on the mounting seat 4 and is used to limit the fixed block 8. The limit assembly 9 includes a latch 91, an operating block 92 and a spring 93. The latch 91 is a horizontally arranged rectangular rod-shaped structure. The latch 91 is arranged on the side wall of the mounting seat 4 and is slidably connected. The latch 91 is plugged into the plug slot 81. The operating block 92 is a round block-shaped structure. The operating block 92 is fixed to the end of the latch 91 away from the fixed block 8. The spring 93 is arranged in the mounting slot 43. The spring 93 is sleeved on the latch 91. One end of the spring 93 is fixed to the inner wall of the mounting slot 43, and the other end of the spring 93 is fixed to the side wall of the operating block 92.
[0034] The bolt 91 is inserted into the mounting seat 4 and the insertion groove 81, which limits the fixing block 8 and the discharge pipe 72. The raw material is put into the feed barrel 71, and the feeding amount is controlled by the valve 73. The raw material enters the screw conveyor 2 through the feed pipe 3 and is transported to the film blowing and drawing machine for manufacturing. When the raw material in the feed barrel 71 needs to be replaced, the staff pulls the bolt 91 out of the insertion groove 81 through the operating block 92, thereby releasing the limiting effect on the fixing block 8, thereby rotating the feed barrel 71 along the axis of the support rod 5 to separate from the mounting seat 4, and then opening the valve 73 to take out the remaining raw material, which is convenient for quickly unloading the raw material in the feed barrel 71, thereby facilitating the replacement of the raw material and improving the production efficiency of the film blowing and drawing machine. The operating block 92 causes the bolt 91 to press against the insertion groove 81 under the elastic force of the spring 93, reducing the probability of the discharge pipe 72 and the feed barrel 71 moving due to the bolt 91 being separated from the insertion groove 81.
[0035] In order to facilitate the rapid limiting of the fixed block 8, the side wall of the pin 91 is provided with a yielding inclined surface 911 which cooperates with the side wall of the fixed block 8. In the process of rotating the discharge tube 72 into the limiting groove 41, the fixed block 8 cooperates with the yielding inclined surface 911 to squeeze the pin 91 into the mounting seat 4, eliminating the tedious operation of the staff to manually pull the operating block 92, thereby facilitating the rapid limiting of the fixed block 8.
[0036] In order to reduce the wear between the feed tube 72 and the limiting groove 41, a rubber pad 10 is fixed to the inner wall of the limiting groove 41. The rubber pad 10 is made of rubber material, and the material is elastic. The feed tube 72 cooperates with the limiting groove 41 and presses against the rubber pad 10, thereby reducing the wear between the feed tube 72 and the limiting groove 41.
[0037] In order to facilitate the movement of the feed barrel 71 , a handle 11 is fixed to the side wall of the feed barrel 71 . The setting of the handle 11 provides a fulcrum for the feed barrel 71 , thereby facilitating the staff to move the feed barrel 71 by pulling it through the handle 11 .
[0038] In order to facilitate timely replenishment of raw materials, a transparent window 12 is provided on the side wall of the feed barrel 71. The setting of the transparent window 12 allows the staff to observe the remaining raw materials in the feed barrel 71 through the transparent window 12, thereby facilitating timely replenishment of raw materials.
[0039] In order to reduce the probability of raw materials remaining on the inner wall of the feed barrel 71, the inner wall of the feed barrel 71 is tilted downward toward the side of the discharge pipe 72. The tilted feed barrel 71 allows the raw materials to roll toward the discharge pipe 72 under the action of gravity, thereby reducing the probability of raw materials remaining on the inner wall of the feed barrel 71.
[0040] The working principle of an automatic feeding device for an upward-blowing film-blowing wire drawing machine in this embodiment is as follows: the latch 91 is inserted into the mounting seat 4 and the insertion slot 81, which limits the fixed block 8 and the feeding pipe 72, and the raw material is put into the feed barrel 71, and then the feeding amount is controlled by the valve 73. The raw material enters the screw conveyor 2 through the feed pipe 3 and is transported to the film-blowing wire drawing machine for manufacturing. When the raw material in the feed barrel 71 needs to be replaced, the staff pulls the latch 91 out of the insertion slot 81 through the operating block 92 , thereby releasing the limiting effect on the fixed block 8, so that the feed barrel 71 is rotated along the axis of the support rod 5 to separate from the mounting seat 4, and then the remaining raw materials are taken out by opening the valve 73, which is convenient for quickly unloading the raw materials in the feed barrel 71, thereby facilitating the replacement of raw materials and improving the production efficiency of the film blowing and wire drawing machine. Under the elastic force of the spring 93, the operating block 92 makes the pin 91 press against the plug-in groove 81, reducing the probability that the pin 91 is separated from the plug-in groove 81 and causing the discharge pipe 72 and the feed barrel 71 to move.
[0041] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
