Description

Technical Field

[0001] The invention relates to the technical field of plastic film receiving devices, in particular to a receiving device of a polyethylene film blowing machine. Background Art

[0002] Polyethylene film is an important type of polymer material products. It is widely used because of its advantages of light weight, high strength, flatness, smoothness and transparency, easy processing and low price. The function of the polyethylene film blowing machine is to heat and melt the plastic particles and blow them into the required film.

[0003] The melted plastic is blown into an expanded tubular bubble structure by a film blowing machine. After being cooled by air, it needs to be flattened by a receiving device to form a double-layer film structure and then rolled up. Most existing receiving devices are based on a frame connected to the film blowing machine. An automatically rotatable through-shaft is horizontally arranged at one end of the frame, and a mechanism for clamping a paper tube is installed in the through-shaft. The film can be rolled up by using a rubber wheel. When replacing a new paper tube, the entire through-shaft needs to be removed. Repeated disassembly and assembly of the through-shaft not only affects the rotation accuracy of the through-shaft, but also causes problems such as cumbersome operation and low efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a material collecting device for a polyethylene film blowing machine, which can form a quick disassembly and assembly structure with a side shaft assembly by utilizing an elastic plug-in shaft assembly, and will not affect the rotation accuracy of the side rotating cylinder; at the same time, a detachable plug sleeve assembly can be used to form an extrusion structure between the outer surface of the elastic plug-in shaft assembly and the inner surface of the paper tube, and a plug column can be used to insert into the inner square groove opened in the plug sleeve assembly and the inner connecting column, which can improve the stability of the convenient installation of the paper tube and provide a safe limit for the winding of the polyethylene film.

[0005] The object of the present invention is achieved through such a technical solution. A material receiving device of a polyethylene film blowing machine includes a fixed frame component, a side shaft assembly, an elastic plug shaft assembly, a plug sleeve assembly and a plug column assembly. The side shaft assembly includes a rotating frame, the elastic plug shaft assembly includes an outer fixed pipe, a fixed plug block and an inner sliding pipe, the plug sleeve assembly includes a fixed plug block, an elastic connection plug block, an opposite plug block and an opposite elastic connection plug block, and the plug column assembly includes an inner square groove and a plug column;

[0006] The front ends of the fixed frame members are respectively fixed with main side plates and opposite side plates, one set of rotating frames is slidably connected with the main side plates and can be raised and lowered, and the other set of rotating frames is fixed with the opposite side plates. The inner ends of each set of rotating frames are screwed with side rotating cylinders, and the inner ends of the side rotating cylinders are symmetrically provided with plug-in end grooves;

[0007] The inner sliding tube is elastically moved outward to slide with the outer fixed tube, the fixed plug block is symmetrically fixed on one end of the outer fixed tube, and a movable plug block is symmetrically fixed on the outside of one end of the inner sliding tube. The elastic plug-in shaft assembly can be inserted into the plug-in end grooves opened in different side rotating cylinders through the fixed plug blocks and the movable plug blocks at both ends;

[0008] The outsides of the outer solid tube and the inner sliding tube can be sleeved with the plug sleeve assembly, the elastic connection plug block is elastically connected to the solid plug block, the opposite elastic connection plug block is elastically connected to the opposite plug block, one end of the opposite elastic connection plug block can be inserted into the solid plug block, and one end of the elastic connection plug block can be inserted into the opposite plug block. An inner connecting column is horizontally fixed to the inner middle part of each group of side rotating cylinders, and an inner square groove is opened in the outer end body of the inner connecting column. After the plug sleeve assemblies located in the outer solid tube and the inner sliding tube are installed in place, the plug column can be inserted into the inner square groove from the insertion point of the solid plug block and the opposite elastic connection plug block, and pass through the insertion point of the opposite plug block and the elastic connection plug block, and in this process, the opposite elastic connection plug block and the elastic connection plug block can be pushed to move elastically outward.

[0009] The use process of the technical solution of the present invention is as follows:

[0010] Before working, first insert an unused paper tube of set length onto the outside of the elastic plug-in shaft assembly, and hold one end of the outer fixed tube with one hand to insert the fixed plug block into the plug-in end groove opened in any one group of side rotating cylinders, and hold the inner sliding tube with the other hand and push the inner sliding tube in the direction of the outer fixed tube. The inner sliding tube is elastically retracted so that the movable plug block at one end of the inner sliding tube can be aligned with the plug-in end groove opened in another group of side rotating cylinders. Under the action of the outward elastic force of the inner sliding tube itself, the movable plug block can be inserted into the aligned plug-in end groove. In this way, the elastic plug-in shaft assembly can be installed between the plug-in end grooves opened in different side rotating cylinders when the paper tube is inserted into the outside of the elastic plug-in shaft assembly.

[0011] Then, different plug sleeve components are respectively put on the outer surfaces of the outer solid tube and the inner sliding tube, and the outer surfaces of the different plug sleeve components are respectively inserted into the two ends of the inner surface of the paper tube, so that the paper tube forms a preliminary connection with the outer solid tube and the inner sliding tube through the plug sleeve components at both ends;

[0012] By coordinating the insertion of the plug post and knocking and moving any one of the plug sleeve assemblies, the two groups of plug sleeve assemblies can be moved to positions facing different inner square grooves, so that after the plug post is inserted into the plug-in joint of the fixed plug block and the opposite elastic connection plug block, it can be accurately inserted into the inner square groove again after passing through the tube wall of the outer fixed tube or the inner sliding tube, and can pass through the plug-in joint of the opposite plug block and the elastic connection plug block. Since the plug post is made of hard material, it will not bend or deform during the insertion process, and will form an outward movement effect on the opposite elastic connection plug block and the elastic connection plug block, so that the opposite elastic connection plug block and the elastic connection plug block can be elastically stretched outward, forming a squeezing effect on the inner surface of the paper tube;

[0013] The plugging column also enables the plug sleeve assembly at one end of the paper tube to form a stable connection with the outer fixed tube and the inner connecting column located inside the outer fixed tube. Similarly, the plug sleeve assembly at the other end of the paper tube forms a stable connection with the inner sliding tube and the inner connecting column located inside the inner sliding tube, thereby enabling the paper tube to be installed safely and stably.

[0014] A rotation drive mechanism is provided at the outer end of a group of side rotary drums connected to the opposite side plates, and the rotation speed of the opposite side rotary drums formed by the rotation drive mechanism matches the discharge speed of the polyethylene film blowing machine;

[0015] After the head end of the polyethylene product blown into a film is fixed to the outside of the paper tube, the polyethylene product blown into a film can gradually form a roll as the polyethylene film blowing machine discharges the material and the side rotating cylinder rotates in coordination;

[0016] After the polyethylene film product forms a whole roll, it is cut and processed. After the two sets of plugs are removed, the movable unloading turnover platform is used to push the inner sliding tube in the direction of the outer fixed tube to disconnect the elastic plug shaft assembly from the side shaft assembly. Then the plug sleeve assembly connected between the outside of the elastic plug shaft assembly and the inner surface of the paper tube is removed, and the paper tube and the polyethylene film product roll rolled up on the outside of the paper tube are unloaded.

[0017] By adopting the above technical solution, the present invention can achieve the following beneficial effects:

[0018] (1) The present invention sets the elastic plug-in shaft assembly and the side shaft assembly in a separate and quickly disassembled form, so that when replacing a new paper roll, there is no need to remove the side rotor, thereby avoiding the problem of increased rotation accuracy error of the side rotor caused by frequent disassembly of the side rotor;

[0019] (2) The present invention not only provides a plug sleeve assembly for clamping and fixing the paper tube on the outside of the elastic plug shaft assembly, but also arranges the elastic connection plug block to be elastically connected to the fixed plug block, and arranges the opposite elastic connection plug block to be elastically connected to the opposite plug block, so that the components formed by the opposite plug block and the opposite elastic connection plug block and the components formed by the fixed plug block and the elastic connection plug block can be inserted between the outside of the elastic plug shaft assembly and the outside of the paper tube to form an outer conical structure, which facilitates the insertion and squeezing of the plug sleeve assembly between the outside of the elastic plug shaft assembly and the inner surface of the paper tube, thereby forming a preliminary connection and fixation between the paper tube and the elastic plug shaft assembly;

[0020] (3) In order to further improve the stability of paper tube installation, the present invention further provides a plug column assembly between the plug sleeve assembly and the elastic plug shaft assembly and the side shaft assembly. After the two sets of plug sleeve assemblies are inserted into place between the outer side of the elastic plug shaft assembly and the inner surface of the paper tube, the plug column is inserted into the plug-in position of the opposite elastic connection plug block and the fixed plug block, which can push the opposite elastic connection plug block to move elastically outward, thereby forming a squeezing effect on the inner surface of the paper tube. As the plug column continues to be inserted, it can pass through the wall of the outer fixed tube or the inner sliding tube and penetrate into the inner square groove provided in the inner connection column body. In the process of inserting the plug block into the plug-in position of the opposite plug block and the elastic connection plug block, the elastic connection plug block can also be elastically moved outward, cooperating with the opposite elastic connection plug block to form a squeezing effect on the inner surface of the paper tube, thereby improving the safety and stability of paper tube installation.

[0021] (4) Furthermore, since the two groups of pins are respectively connected to the two ends of the paper tube, they can also form a certain limit on the winding process of the polyethylene film product to prevent the polyethylene film product from being skewed during the winding process.

[0038] like Figure 1-Figure 11 As shown, a material receiving device of a polyethylene film blowing machine, a main side plate 301 and an opposite side plate 303 are fixed to both sides of the front end of a fixed frame member 1, one set of rotating frames 306 is slidably connected to the main side plate 301 and can be raised and lowered, and another set of rotating frames 306 is fixed to the opposite side plate 303, and the inner end of each set of rotating frames 306 is screwed with a side rotating cylinder 309, and the inner end of the side rotating cylinder 309 is symmetrically provided with a plug-in end groove 310;

[0039] The inner sliding tube 405 is elastically moved outward to slide with the outer fixed tube 401, and the fixed plug block 403 is symmetrically fixed on one end of the outer fixed tube 401. A movable plug block 406 is symmetrically fixed on the outside of one end of the inner sliding tube 405. The elastic plug-in shaft assembly 4 can be inserted into the plug-in end grooves 310 opened in different side rotating cylinders 309 through the fixed plug blocks 403 and the movable plug blocks 406 at both ends.

[0040] The outer sides of the outer fixed tube 401 and the inner sliding tube 405 can be sleeved with the plug sleeve assembly 5, the elastic connection plug block 503 is elastically connected to the fixed plug block 502 to form an integral structure, the opposite elastic connection plug block 508 is elastically connected to the opposite plug block 507 to form an integral structure, one end of the opposite elastic connection plug block 508 can be inserted into the fixed plug block 502, and one end of the elastic connection plug block 503 can be inserted into the opposite plug block 507 to form an outer conical surface structure together, and the inner middle part of each set of side rotating cylinders 309 is horizontally fixed with an inner connection plug block 503. The connecting column 606 and the inner square groove 607 are provided in the outer end body of the inner connecting column 606. After the plug sleeve assemblies 5 located in the outer fixed tube 401 and the inner sliding tube 405 are installed in place, the plug column 614 can be inserted inwardly into the inner square groove 607 from the insertion point of the fixed plug block 502 and the opposite elastic connecting plug block 508, and pass through the insertion point of the opposite plug block 507 and the elastic connecting plug block 503. In this process, the opposite elastic connecting plug block 508 and the elastic connecting plug block 503 can be pushed to move elastically outward.

[0041] Here’s how it works:

[0042] The receiving device is installed at the discharge end of the polyethylene film blowing machine and is used to form a roll of polyethylene products blown into a film;

[0043] First, insert the unused paper tube 7 of set length onto the outside of the elastic plug-in shaft assembly 4, and hold one end of the outer fixed tube 401 with one hand to insert the fixed plug block 403 into the plug-in end groove 310 opened in any one group of side rotating cylinders 309, and hold the inner sliding tube 405 with the other hand and push the inner sliding tube 405 in the direction of the outer fixed tube 401, so that the inner sliding tube 405 is elastically retracted, so that the movable plug block 406 at one end of the inner sliding tube 405 can be opposite to the plug-in end groove 310 opened in another group of side rotating cylinders 309, and under the action of the outward elastic force of the inner sliding tube 405 itself, the movable plug block 406 can be inserted into the opposite plug-in end groove 310, so that the elastic plug-in shaft assembly 4 can be installed between the plug-in end grooves 310 opened in different side rotating cylinders 309 when the paper tube 7 is inserted into the outside of the elastic plug-in shaft assembly 4;

[0044] Then, different plug sleeve components 5 are respectively put on the outer surface of the outer solid tube 401 and the inner sliding tube 405, and the outer surfaces of different plug sleeve components 5 are respectively inserted into the two ends of the inner surface of the paper tube 7, so that the paper tube 7 forms a preliminary connection with the outer solid tube 401 and the inner sliding tube 405 through the plug sleeve components 5 at both ends;

[0045] Since the length of the paper tube 7 is a uniformly set length, and the theoretical length between the inner square grooves 607 opened in the inner connecting column 606 fixed in the middle of the two different sets of side rotating cylinders 309 remains unchanged, the insertion of the plug column 614 and the knocking and moving of any set of plug sleeve components 5 can make the two sets of plug sleeve components 5 move to the position facing the different inner square grooves 607, so that after the plug column 614 is inserted into the plugging position of the fixed plug block 502 and the opposite elastic connecting plug block 508, the plug sleeve components 5 can be moved to the position facing the different inner square grooves 607. 01 or the tube wall of the inner sliding tube 405, it can be accurately inserted into the inner square groove 607 again, and can pass through the insertion point of the opposite plug block 507 and the elastic connection plug block 503. Since the plug column 614 is made of hard material, it will not bend or deform during the insertion process, and will form an outward movement effect on the opposite elastic connection plug block 508 and the elastic connection plug block 503, so that the opposite elastic connection plug block 508 and the elastic connection plug block 503 can be elastically stretched outward, forming a squeezing effect on the inner surface of the paper tube 7;

[0046] Due to the plugging effect of the plug post 614, the plug sleeve assembly 5 at one end of the paper tube 7 forms a stable connection with the outer solid tube 401 and the inner connecting post 606 located inside the outer solid tube 401. Similarly, the plug sleeve assembly 5 at the other end of the paper tube 7 forms a stable connection with the inner sliding tube 405 and the inner connecting post 606 located inside the inner sliding tube 405, so that the paper tube 7 is safely and firmly installed.

[0047] A rotation drive mechanism is provided at the outer end of a group of side rotary cylinders 309 connected to the opposite side plate 303, and the rotation speed of the opposite side rotary cylinders 309 formed by the rotation drive mechanism matches the discharge speed of the polyethylene film blowing machine;

[0048] After the head end of the polyethylene product blown into a film is fixed to the outside of the paper tube 7, the polyethylene product blown into a film can be gradually formed into a coil as the polyethylene film blowing machine discharges the material and the side rotating cylinder 309 rotates in coordination;

[0049] And because the two groups of plug posts 614 are respectively located at the two ends of the paper tube 7, a certain safety limit effect can be formed during the winding process of the polyethylene product blown into a film;

[0050] After the polyethylene film product forms a whole roll, it is cut and processed. After the two groups of plug posts 614 are removed, the movable unloading turnover platform is used to push the inner sliding tube 405 in the direction of the outer fixed tube 401, so that the elastic plug shaft assembly 4 and the side shaft assembly 3 can be disconnected, and then the plug sleeve assembly 5 connected between the outside of the elastic plug shaft assembly 4 and the inner surface of the paper tube 7 is removed, and the paper tube 7 and the polyethylene film product roll rolled up on the outside of the paper tube 7 are unloaded.

[0051] The specific structure of the fixed frame component 1, the rubber wheel component 2 and the side shaft component 3 is as follows: Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the upper parts of both ends of the fixed frame body 101 are symmetrically fixedly connected with side top seats 102, and the fixed frame body 101 is a frame structure. The device is fixed at the discharge position of the polyethylene film blowing machine through the fixed frame body 101;

[0052] The introduction of the rubber wheel component 2 can guide the film blown by the polyethylene film blowing machine before entering the outside of the paper tube 7. A rubber wheel rotating seat 201 is symmetrically fixedly installed in each group of side top seats 102, and the two ends of the rubber wheel rotating shaft 202 are respectively rotatably connected to the coaxially opposite rubber wheel rotating seats 201; and the outer shaft end of one group of rubber wheel rotating shafts 202 is connected to a mechanism that is transmission-connected to the rotating drive mechanism arranged at the outer end of the side rotating cylinder 309, so that the rubber wheel rotating shaft 202 can keep rotating synchronously with the side rotating cylinder 309;

[0053] The rubber wheel components 2 may be introduced in multiple groups according to actual conditions. The blown polyethylene film must first be inserted between the two groups of rubber wheel shafts 202 before it can be rolled up outside the paper tube 7. The two groups of rubber wheel shafts 202 can not only form a guide for the polyethylene film during the rolling process, but also avoid the problem of different tightness of the polyethylene film during the process of rolling up outside the paper tube 7.

[0054] The main side plate 301 is fixedly connected to one side of the front end of the fixed frame body 101, and the opposite side plate 303 is fixedly connected to the other side of the front end of the fixed frame body 101, and the main side plate 301 and the opposite side plate 303 are horizontally opposite to each other, and the adjustment slide groove 302 is vertically opened in the main body of the main side plate 301, and the main body of the opposite side plate 303 is provided with an opposite fixing groove 304;

[0055] The outer end of each set of rotating frames 306 is fixedly connected to a connecting socket 305, and the main rotating shaft 308 is coaxially fixedly connected to the inner end of the side rotating cylinder 309. The inner end of each set of rotating frames 306 is also fixedly installed with an inner rotating seat 307, and the main rotating shaft 308 on the same side is rotatably connected in the inner rotating seat 307;

[0056] One set of connection sockets 305 is fixedly connected in the opposite fixed groove 304, and the other set of connection sockets 305 is slidably connected in the adjustment slide groove 302. After the two sets of connection sockets 305 are installed, the two sets of side rotating cylinders 309 are coaxially facing each other in theory.

[0057] A through hole is also provided in the middle of the main body of the connecting socket 305, which is opposite to the inner rotating seat 307, so as to facilitate the passage of the shaft end of the main rotating shaft 308;

[0058] The shaft end of the main rotating shaft 308 installed in the opposite side plate 303 is connected to a rotation driving mechanism, which can drive the rotation of the main rotating shaft 308 and the side rotating cylinder 309;

[0059] The lower end of the main body of the main side plate 301 is threadedly connected with an adjusting bolt 312, and the inner end of the adjusting bolt 312 is rotatably connected to the bottom end of the connecting socket 305 slidably connected in the adjusting slot 302. By rotating the adjusting bolt 312, the height of the connecting socket 305 slidably connected in the adjusting slot 302 can be adjusted, so that the height of a group of side rotating cylinders 309 connected to the main side plate 301 can be fine-tuned in real time, thereby reducing the occurrence of the problem of roll deflection caused by the winding action of the elastic plug-in shaft assembly 4 inserted between the two groups of side rotating cylinders 309 and the paper roll 7 installed and fixed outside the elastic plug-in shaft assembly 4.

[0060] The specific structure of the elastic plug shaft assembly 4 is as follows Figure 6 and Figure 7 As shown, the fixed insert 402 is fixedly connected to the inner hole of one end of the outer fixed tube 401, and the fixed insert block 403 is symmetrically fixedly connected to the outside of the fixed insert 402;

[0061] The inner end of the inner hole of the fixed insert 402 is fixedly connected to the inner fixed seat 404, and the inner end of the inner hole of the inner slide tube 405 is fixedly connected to the inner movable seat 409. One end of the inner compression spring 410 is clamped on the side of the inner movable seat 409, and the other end is clamped on the side of the inner fixed seat 404. The elastic power formed by the inner compression spring 410 can make the inner slide tube 405 elastically move outward.

[0062] The two sides of the main body of the outer fixed tube 401 are symmetrically provided with limit slide grooves 407, and the two sides of the inner end of the outer side of the inner slide tube 405 are symmetrically fixed with limit sliders 408, and the limit sliders 408 on the same side are slidably connected in the limit slide grooves 407. The limit sliders 408 can provide a travel range for the sliding range of the limit slide grooves 407, so that the inner slide tube 405 can move elastically within a certain range;

[0063] The outer side of the inner slide tube 405 near the movable plug block 406 is also provided with embossed teeth 411, which can increase the friction of the hand-held grip and facilitate the movement of the inner slide tube 405;

[0064] The inner hole of the inner end of the side rotating cylinder 309 is provided with an insertion chamfer 311, and the outer ends of the fixed insert tube 402 and the inner sliding tube 405 are also provided with rounded corners, which can more conveniently insert the fixed insert tube 402 and the inner sliding tube 405 into the inner hole of the side rotating cylinder 309.

[0065] The specific structure of the plug sleeve assembly 5 and the plug column assembly 6 is as follows: Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, one end of the outer fixed tube 401 and the inner sliding tube 405 are both installed with a plug sleeve assembly 5 and a plug column assembly 6. For ease of understanding, Figure 8 Only one end of the outer fixed tube 401 is used as a schematic diagram; the outer sides of the outer fixed tube 401 and the inner sliding tube 405 are symmetrically fixed with positioning side platforms 501, the positioning groove 504 is provided on the inner surface of the fixed plug block 502, and the opposite positioning groove 509 is provided on the inner surface of the opposite plug block 507. The positioning side platform 501 can form a clamping effect on the positioning groove 504 and the opposite positioning groove 509, so that the component formed by the connection between the fixed plug block 502 and the elastic connection plug block 503 and the component formed by the connection between the opposite plug block 507 and the opposite elastic connection plug block 508 can be installed on the outer side of the outer fixed tube 401 and the inner sliding tube 405 in a certain rotation orientation;

[0066] And because the outer diameter of the inner sliding tube 405 is smaller than the outer diameter of the outer fixed tube 401, the inner diameter of the plug sleeve assembly 5 matched with the inner sliding tube 405 is actually different from the inner diameter of the plug sleeve assembly 5 matched with the outer fixed tube 401, that is, the inner hole formed by the component formed by the connection of the fixed plug block 502 and the elastic connection plug block 503 installed outside the outer fixed tube 401 and the component formed by the connection of the opposite plug block 507 and the opposite elastic connection plug block 508 matches the outer diameter of the outer fixed tube 401, and the inner hole formed by the component formed by the connection of the fixed plug block 502 and the elastic connection plug block 503 installed outside the inner sliding tube 405 and the component formed by the connection of the opposite plug block 507 and the opposite elastic connection plug block 508 matches the outer diameter of the inner sliding tube 405;

[0067] One end of the fixed plug block 502 is transversely provided with a plugging groove 505, one end of the opposite plug block 507 is transversely provided with a opposite plugging groove 511, one end of the opposite elastic connection plug block 508 is transversely fixed with a opposite plugging boss 510, and one end of the elastic connection plug block 503 is transversely fixed with a plugging boss 506, the opposite plugging boss 510 can be inserted into the plugging groove 505, the plugging boss 506 can be inserted into the opposite plugging groove 511, and there is a certain matching gap between the opposite plugging boss 510 and the plugging groove 505, and between the plugging boss 506 and the opposite plugging groove 511, so as to facilitate the opposite elastic connection plug block 508 and the elastic connection plug block 503 to form an outward elastic deformation;

[0068] The outer fixed tube 401 and the inner sliding tube 405 are provided with square holes 605 for passing the plug posts 614;

[0069] The entry square hole 601 is provided at one end of the fixed plug block 502 and passes through the plugging groove 505 and the main body of the fixed plug block 502. The exit square hole 603 is provided at one end of the opposite plug block 507 and passes through the opposite plugging groove 511 and the main body of the opposite plug block 507. The opposite plugging boss 510 is provided with an entry push inclined groove 602, and the plugging boss 506 is provided with an exit push inclined groove 604.

[0070] After the plug sleeve assembly 5 is assembled, the inlet square hole 601 is directly opposite to the inlet push inclined slot 602, and the outlet square hole 603 is directly opposite to the outlet push inclined slot 604;

[0071] Both sides of one end of the plug post 614 are provided with push inclined surfaces 616, and the inclination angle of the push inclined surfaces 616 is the same as the inclination angle of the entry push inclined groove 602 and the exit push inclined groove 604, so that when the plug post 614 is inserted into the entry square hole 601 and the exit square hole 603, it can form a sliding fit with the entry push inclined groove 602 and the exit push inclined groove 604, so that the insertion of the plug post 614 forms an elastic outward squeezing effect on the inner surface of the paper tube 7.

[0072] The main body of the inner connecting column 606 is also provided with an elastic column sliding hole 608 which is connected to the inner square groove 607. A slide table 609 is slidably connected to the elastic column sliding hole 608. The inner end of each group of elastic column sliding holes 608 is fixedly connected to an inner slide seat 610. The elastic column 611 is fixedly connected to the inner end of the slide table 609 and is slidably connected to the inner slide seat 610. The outer seat 612 is fixedly connected to the inner end surface of the inner connecting column 606. The inner top spring 613 is located in the elastic column sliding hole 608, and one end is fixed to one side of the outer seat 612, and the other end is fixed to one side of the slide table 609, so that the elastic column 611 can be elastically moved toward the side of the inner square groove 607.

[0073] Side spring holes 615 are symmetrically provided on both sides of the middle of the main body of the plug post 614, so that after the plug post 614 is inserted into place, the spring post 611 and the side spring hole 615 form an elastic snap connection, so that not only can the main body of the plug post 614 be evenly distributed on both sides of the paper tube 7 each time the plug post 614 is inserted, forming a good limiting effect on the outside of the paper tube 7, but also the plug post 614 will not slip off easily during the rolling process of the polyethylene film product.
