Description

Technical Field

[0001] This utility model relates to the field of plastic baling machine technology, and in particular to a high-efficiency baling machine for the production of plastic products. Background Technology

[0002] Plastic products are various products made primarily from plastic through different processing techniques. They are industrial products produced in large quantities, in diverse forms, and mostly in a scattered state. After production, they need to be centrally stored and transported. Direct stacking will occupy a lot of space due to their loose or scattered characteristics, resulting in wasted storage capacity and low transportation loading rate. They may also scatter or be damaged due to collisions and compression. Therefore, packaging machines for plastic product production are needed to compress the volume of materials, improve the utilization rate of storage space, increase transportation loading efficiency, and reduce logistics costs, while avoiding material scattering and loss.

[0003] Early plastic product packaging equipment mainly consisted of a manually pushed conveyor platform and bolt-locked fixed supports. Because the conveyor platform relied on manual pushing for material transfer, it was inefficient. The fixed supports clamped the products by manually tightening bolts, resulting in poor adaptability and requiring frequent shutdowns for adjustments. To solve these problems, existing packaging machines use servo motor-driven conveyor belts for automatic material transport and cylinder or screw-driven clamping mechanisms to replace manual fixing, ensuring precise positioning. However, in actual use, because the packaging film is fixed to the flange with bolts, installation requires inserting the roll and tightening the bolts, and disassembly requires tools to remove the flange. Changing rolls is time-consuming and labor-intensive, hindering continuous production and reducing packaging efficiency, thus failing to meet user needs. Utility Model Content

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when it is necessary to replace the packaging film roll, the slide rod and the positioning protrusion slide into the film roll shaft, and the gathering shell moves downward synchronously inside the film roll shaft to squeeze the inclined panel, so that the positioning pin gathers towards the center of the film roll shaft. The positioning pin exits from the positioning hole opened in the old packaging film roll, releasing the fixation of the old film roll. The new film is put on the outside of the film roll shaft, the gathering shell moves upward and separates from the inclined panel, and the spring pushes the positioning pin to insert into the positioning hole on the inside of the new packaging film roll, realizing the automatic locking of the new film roll.

The clamping block compresses the inner spring 2, and the spring 2 generates a reverse elastic force, pushing the clamping block to fit tightly against the surface of the product to achieve a rapid clamping effect. For plastic products of different sizes, when the lead screw is rotated, the lead screw generates axial displacement through the threaded engagement with the limiting shell, pushing the guide shell to slide along the inside of the limiting shell, thereby changing the distance between the clamping blocks on both sides.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model is provided: a high-efficiency packaging machine for plastic product production, including a packaging table 1, a quick-change mechanism 2 is provided at the top front left end of the packaging table 1, the quick-change mechanism 2 is used to quickly change the packaging film, a fixing mechanism 3 is provided at the top of the packaging table 1, the fixing mechanism 3 is used to fix the plastic products, and a conveying mechanism 4 is provided at the rear side of the packaging table 1, the conveying mechanism 4 is used to convey the plastic products.

[0033] The quick-change mechanism 2 includes a film roll 201, which serves as a support carrier for packaging the film roll. Its bottom is rotatably connected to the packaging table 1, ensuring the film roll rotates freely during the winding action. The bottom of the film roll 201 is rotatably connected to the top front right side of the packaging table 1. A slide rod 202 is provided at the top of the film roll 201, serving as a manual operating lever that passes through the top of the film roll 201. A positioning protrusion 203 is fixedly connected to the right side of the outer wall of the slide rod 202. When the slide rod 202 is pressed down and rotated, the protrusion engages with the top of the film roll 201, achieving axial locking of the slide rod 202. The bottom ends of both the slide rod 202 and the positioning protrusion 203 pass through the top of the film roll 201 and are fixedly connected to a gathering shell 204. The gathering shell 204 moves vertically by pressing the inclined panel 2. 08. The vertical force is converted into the lateral contraction force of the positioning pin 206. The inner bottom of the membrane roll 201 is fixedly connected to the connecting post 205. The connecting post 205 provides a fixed fulcrum for the spring 207. Multiple springs 207 are fixedly connected to the top of the outer wall of the connecting post 205. The springs 207 provide the restoring force for the positioning pin 206. The other end of each of the multiple springs 207 is fixedly connected to the positioning pin 206. The end of the positioning pin 206 can be inserted into the positioning hole on the inner side of the packaging membrane roll to achieve circumferential fixation of the membrane roll. One end of each of the multiple positioning pins 206 penetrates the inner wall of the membrane roll 201. The top of the other end of each of the multiple positioning pins 206 is fixedly connected to the inclined plate 208. The top of one side of each of the multiple inclined plates 208 is slidably connected to the inner wall of the gathering shell 204.

[0034] A photoelectric sensor is installed at the top rear right end of the packaging table 1. The photoelectric sensor sends a signal to the control system by detecting whether the material has reached the inlet of the turntable 302, which coordinates the stopping of the conveying mechanism 4 and the starting of the push plate 7. The height of the turntable 302 matches the height of the conveyor belt 404. Matching the height of the turntable 302 with the height of the conveyor belt 404 ensures a smooth transition of the material from the conveyor belt 404 to the turntable 302.

[0035] Specifically, when the packing film roll needs to be replaced, the slide bar 202 is pushed downwards. The slide bar 202 drives the positioning protrusion 203 to slide into the film roll shaft 201. The gathering shell 204 moves downwards synchronously inside the film roll shaft 201. During the downward movement, the gathering shell 204 will press the inclined plate 208 through the inclined surface, causing multiple inclined plates 208 to drive the positioning pin 206 to gather towards the center of the film roll shaft 201. The positioning pin 206 compresses the spring 207 on the outer wall of the connecting column 205, causing the end of the positioning pin 206 to exit from the positioning hole opened in the old packing film roll, thereby releasing the fixation of the old film roll. After the positioning protrusion 203 is fully inserted into the inner side of the film roll shaft 201, the slide bar 202 is rotated to make the positioning protrusion 203 rotate. At this time, the film... The top of the roll 201 forms an axial limit on the positioning protrusion 203, which can prevent the slide rod 202 from resetting upwards and maintain the gathering state of the positioning pin 206. The old packaging film roll is removed from the film roll 201 to complete the disassembly. When installing the new packaging film, the new film is placed on the outside of the film roll 201, and the slide rod 202 is rotated in the opposite direction to make the positioning protrusion 203 disengage from the limit at the top of the film roll 201. The slide rod 202 moves upwards under the indirect action of the restoring force of the spring 207. The gathering shell 204 moves upwards and disengages from the inclined panel 208. The spring 207 pushes the positioning pin 206 to extend outwards from the film roll 201 and insert it into the positioning hole on the inside of the new packaging film roll to fix the new film roll. By quickly changing the film roll, the packaging efficiency is effectively improved.

[0036] Reference Figure 1 , Figure 2 and Figure 4 The fixing mechanism 3 includes a servo motor 301, which is the power source for the turntable 302. The top end of the servo motor 301 is fixedly connected to the bottom end of the packing table 1. The output end of the servo motor 301 passes through the packing table 1 and is fixedly connected to the turntable 302. The turntable 302 is a platform for carrying plastic products. Limiting shells 303 are fixedly connected to the left and right sides of the top of the turntable 302. The limiting shells 303 restrict the guide shells 304 to slide only in the horizontal direction. Guide shells 304 are slidably connected inside both limiting shells 303. 4. The guide shell 304 provides longitudinal extension space for the clamping block 305. The clamping block 305 is slidably connected inside both guide shells 304. The clamping block 305 is a component that directly contacts the plastic product. Spring 2 306 is fixedly connected to the opposite side of the two clamping blocks 305. Spring 2 306 provides continuous elastic force to the clamping block 305. The opposite side of the two spring 2 306 is fixedly connected to the inner wall of the corresponding guide shell 304. The opposite side of the two limiting shells 303 is provided with pitch changing component 307.

[0037] The pitch control assembly 307 includes two lead screws 3071. The lead screws 3071 rotate to drive the guide shell 304 to slide along the limiting shell 303, precisely adjusting the initial distance between the clamping blocks 305 on both sides. The adjacent sides of the two lead screws 3071 are respectively threaded to the corresponding limiting shell 303. The adjacent sides of the two lead screws 3071 pass through the corresponding limiting shell 303 and one side of the guide shell 304 and are fixedly connected to the limiting plate 3072. The limiting plate 3072 prevents the guide shell 304 from disengaging from the lead screw 3071. When the lead screw 3071 is rotated in the opposite direction, the limiting plate 3072 drives the guide shell 304 to reset synchronously.

[0038] Specifically, when the plastic product is fed into the turntable 302 by the push plate 7, the edge of the product contacts the inclined surface of the clamping block 305. The inclined surface is subjected to force and generates a lateral thrust, causing the clamping blocks 305 on both sides to contract inward into the guide shell 304. At this time, the clamping block 305 compresses the inner spring 306, and the spring 306 generates a reverse elastic force, pushing the clamping block 305 to fit tightly against the surface of the product, thereby achieving the clamping effect. For plastic products of different sizes, by rotating the lead screw 3071, the lead screw 3071 generates axial displacement through the threaded engagement with the limiting shell 303, pushing the guide shell 304 to slide along the inside of the limiting shell 303, thereby changing the distance between the clamping blocks 305 on both sides. When the lead screw 3071 is rotated in the opposite direction, the limiting piece 3072 can drive the guide shell 304 to reset synchronously. The servo motor 301 drives the turntable 302 to rotate, which can drive the fixed product to rotate with the turntable 302. With the wrapping action of the packaging film, all-round packaging is achieved.

[0039] Reference Figure 1 , Figure 2 and Figure 5The conveying mechanism 4 includes a frame 401 and a conveyor belt 404. The front side of the frame 401 is fixedly connected to the rear side of the packing table 1. Conveyor rollers 402 are rotatably connected to the left and right sides of the frame 401. The two conveyor rollers 402 drive the conveyor belt 404 through friction with it. The two conveyor rollers 402 are connected via the conveyor belt 404, and the conveyor belt 404 achieves horizontal conveying of plastic products through the transmission of the conveyor rollers 402. A servo motor 403 is fixedly connected to the right front end of the frame 401. The servo motor 403 controls the running speed of the conveyor belt 404 by adjusting its speed, synchronizing with the packing rhythm. The output end of the servo motor 403 passes through the frame 401 and is fixedly connected to the front end of the corresponding conveyor roller 402. Limiting components 4 are provided on the front and rear sides of the frame 401. 05; The limiting component 405 includes multiple fixing blocks 4051, which provide sliding guides for the connecting rods 4052. One side of each fixing block 4051 is fixedly connected to the front and rear sides of the frame 401. The inner walls of each fixing block 4051 are slidably connected to the connecting rods 4052, which are used to adjust the position of the limiting plate 4054. The top of each fixing block 4051 is threaded with bolts 4053. When the bolts 4053 are tightened, their bottom ends press against the surface of the connecting rods 4052, locking the position of the limiting plate 4054 through friction. The front and rear sides of the top of the frame 401 are provided with limiting plates 4054, which are used to constrain the lateral displacement of the material. The opposite sides of two limiting plates 4054 are respectively fixedly connected to one end of the corresponding connecting rod 4052.

[0040] Specifically, when the servo motor 403 starts, the output shaft drives the right conveyor roller 402 to rotate. Through the friction between the conveyor belt 404 and the two conveyor rollers 402, the conveyor belt 404 is driven to run horizontally along the frame 401, realizing the continuous conveying of plastic products from the production line to the packaging table 1. When conveying plastic products of different widths, the bolt 4053 on the top of the fixing block 4051 is loosened, and the limiting plate 4054 is pushed to drive the connecting rod 4052 to slide along the fixing block 4051 until the distance between the two limiting plates 4054 matches the width of the material. Then the bolt 4053 is tightened, and the bottom end of the bolt 4053 contacts the surface of the connecting rod 4052. The position is locked by the friction between the bolt 4053 and the connecting rod 4052.

[0041] Reference Figure 5A connecting plate 5 is fixedly connected to the left rear end of the frame 401. The connecting plate 5 provides a mounting point for the cylinder 6. The cylinder 6 is fixedly connected to the rear end of the connecting plate 5. The output end of the cylinder 6 is connected to the push plate 7. The piston rod provides thrust to smoothly push the products on the conveyor belt 404 into the turntable 302 through extension and retraction. The output end of the cylinder 6 passes through the rear side of the connecting plate 5 and is fixedly connected to the push plate 7. Guide rods 8 are slidably connected to the left and right sides inside the connecting plate 5. The guide rods 8 ensure that the push plate 7 moves only in the horizontal direction to avoid the products from shifting due to uneven force during pushing. The front ends of the two guide rods 8 are fixedly connected to the rear side of the push plate 7.

[0042] Specifically, when the plastic products are conveyed to the rear of the packaging table 1, the cylinder 6 is activated and drives the push plate 7 through the output end to smoothly push the material into the turntable 302. At this time, the guide rod 8 plays a guiding and limiting role on the push plate 7.

[0043] Working principle: When the packaging film roll needs to be replaced, the slide bar 202 is pushed downwards. The slide bar 202 drives the positioning protrusion 203 to slide into the film roll shaft 201. The gathering shell 204 moves downwards synchronously inside the film roll shaft 201. Since the inner wall of the gathering shell 204 slides in contact with the top of the inclined plate 208, the inclined plate 208 is squeezed by the inclined plate during the downward movement. This causes multiple inclined plates 208 to drive the positioning pin 206 to gather towards the center of the film roll shaft 201. The positioning pin 206 compresses the spring 207 on the outer wall of the connecting column 205, causing the end of the positioning pin 206 to exit from the positioning hole of the old packaging film roll, releasing the fixation of the old film roll. After the positioning protrusion 203 is fully inserted into the inner side of the film roll shaft 201, the slide bar 202 is rotated to make the positioning protrusion... When 203 rotates, the top of the film roll 201 forms an axial limit on the positioning protrusion 203, preventing the slide rod 202 from resetting upwards and maintaining the convergence state of the positioning pin 206. The old packaging film roll is removed from the film roll 201, completing the disassembly. When installing the new packaging film, the new film is placed on the outside of the film roll 201, and the slide rod 202 is rotated in the opposite direction to make the positioning protrusion 203 disengage from the limit at the top of the film roll 201. The slide rod 202 moves upwards under the indirect action of the restoring force of the spring 207, and the convergence shell 204 moves upwards and disengages from the inclined panel 208. The spring 207 pushes the positioning pin 206 to extend outwards from the film roll 201 and insert it into the positioning hole on the inside of the new packaging film roll, realizing the automatic locking of the new film roll. By quickly changing the film roll, the packaging efficiency is improved.

[0044] Furthermore, when the plastic product is fed into the turntable 302 by the push plate 7, the edge of the product first contacts the inclined surface of the clamping block 305. The inclined surface is subjected to force to generate a lateral thrust, causing the clamping blocks 305 on both sides to retract into the guide shell 304. The clamping block 305 compresses the inner spring 306, and the spring 306 generates a reverse elastic force, pushing the clamping block 305 to tightly fit the surface of the product to achieve a rapid clamping effect. For plastic products of different sizes, when the lead screw 3071 is rotated, the lead screw 3071 generates axial displacement through the threaded engagement with the limiting shell 303, pushing the guide shell 304 to slide along the inside of the limiting shell 303, thereby changing the distance between the clamping blocks 305 on both sides. When the lead screw 3071 is rotated in the opposite direction, the limiting piece 3072 can drive the guide shell 304 to reset synchronously. The servo motor 301 drives the turntable 302 to rotate, which can drive the fixed product to rotate with the turntable 302, and achieve all-round packaging in conjunction with the wrapping film.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
