Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and relates to an attached chain plate chain conveyor with a film guiding mechanism for use in conjunction with a horizontal winding packaging machine. Background Art

[0002] In the field of transportation packaging, a horizontal winding packaging machine can use a PE stretch film to perform vertical winding packaging on goods. After packaging, the appearance of the goods is beautiful, and the dust-proof and waterproof performance is significantly improved, which is favored by the majority of users. When the horizontal winding packaging machine is working, the film rack for placing the PE stretch film roll makes a circular motion in the vertical direction along with the closed rotating ring. The goods are placed on a conveyor used in conjunction with the horizontal winding packaging machine and pass through the middle of the closed rotating ring and run forward. A gap greater than or equal to the width dimension of the PE stretch film (taking the width of the PE stretch film as 500 mm as an example, the gap size ≥ 500 mm) will be opened between the front and rear sections of the conveyor used in conjunction with the horizontal winding packaging machine, so that the PE stretch film can wind around the bottom of the goods. This structure is suitable for goods with a longer running direction on the conveyor. However, when the user needs to package goods with a "川" - shaped tray or cushion block placed at the bottom or goods with a shorter length in the running direction of the conveyor, the goods cannot pass through the two sections of the conveyor, and the goods will tilt at the gap between the two sections of the conveyor, resulting in abnormal operation of the equipment. If only the distance between the two sections of the conveyor is reduced so that the goods can pass through normally, the PE stretch film will wind around the bottom of the conveyor carrying the goods when winding around the bottom of the goods. When the goods run forward, the wound PE stretch film will break, be damaged, etc., and cannot meet the packaging requirements. For this situation, a design of an attached chain plate chain conveyor with a film guiding mechanism has been carried out. Summary of the Invention

[0003] In order to make up for the deficiencies of the prior art, the present invention designs an attached chain plate chain conveyor with a simple structure and convenient use for use in conjunction with a horizontal winding packaging machine. This equipment expands the application range of the horizontal winding packaging machine, enabling goods with a "川" - shaped tray or cushion block placed at the bottom or goods with a shorter length in the running direction of the conveyor to be wound and packaged using a horizontal winding packaging machine, and can be widely applied to industries with such situations, such as the board and building materials industries.

[0004] The present invention is realized through the following technical solutions:

[0005] An attached chain plate chain conveyor for use in conjunction with a horizontal winding packaging machine, characterized in that: the attached chain plate chain conveyor includes legs, a long frame, a short frame, a conveying mechanism, and a film guiding mechanism;

[0006] Note: The Chinese character "川" in the text is kept as it is because it may be a specific term or symbol in the original context. If it has a specific meaning that needs to be translated, more context information is required.Several horizontal racks are installed at the upper end of the legs through several longitudinal beams. The racks on both sides are short racks, and the rack in the middle is a long rack. The protruding part at the front end of the long rack passes through the closed swivel of the horizontal wrapping packaging machine; the conveying mechanism for transporting the goods forward is installed on the long rack and the short rack;

[0007] The film guide mechanism is installed on the protruding part of the front end of the long frame and is located within the rotating packaging range of the film frame installed on the closed swivel. When the goods move forward while being wrapped with packaging film, the film guide mechanism will smoothly move the lower side of the packaging film forward and guide it out.

[0008] Four mutually parallel frames are installed above the legs, the protruding parts of the front ends of the two middle long frames pass through the closed swivel of the horizontal wrapping packaging machine, and the two frames on both sides are short frames.

[0009] The conveying mechanism adopts an attached chain plate chain sprocket assembly; a set of attached chain plate chain sprocket assemblies is installed between the two ends of each long frame and between the two ends of each short frame, and each attached chain plate chain runs forward synchronously to convey the goods forward; the attached chain plate chain sprocket assembly is connected to the drive motor through a transmission device.

[0010] In the conveying mechanism, the transmission device includes a driving sprocket assembly and a driven sprocket assembly mounted on a frame;

[0011] A first transmission sprocket and a second transmission sprocket are fixedly mounted on the first transmission shaft in the driving sprocket assembly, and a driving sprocket of the chain plate chain sprocket assembly on the short frame is also mounted on the first transmission shaft;

[0012] The driving motor is installed on the supporting leg and connected with the first driving sprocket in the driving sprocket assembly and the first driving shaft through the first driving chain. The driving sprocket assembly is driven to rotate by the rotation of the driving motor, and then the chain attached to the short frame is driven to move to transport the goods.

[0013] The third transmission sprocket is fixedly mounted on the second transmission shaft in the driven sprocket assembly, and the driving sprocket of the chain plate chain sprocket assembly on the long frame is also mounted on the second transmission shaft; the driven sprocket assembly is mounted on the front end of the long frame;

[0014] The second transmission sprocket in the driving sprocket assembly is connected to the third transmission sprocket in the driven sprocket assembly through the second transmission chain; the driven sprocket assembly is connected to the attached chain plate chain on the long frame and drives it to move forward, and transports the goods forward together with the attached chain plate chain on the short frame.

[0015] The film guiding mechanism comprises a film guiding driving sprocket assembly, a film guiding driven sprocket assembly, and a film guiding chain connected therebetween;

[0016] The film guide driving sprocket assembly includes a film guide mechanism driving sprocket, a film guide transmission shaft, and a film guide sprocket which are connected in sequence. The transmission shaft is installed on a long frame via a seat bearing. The film guide sprocket is connected to the film guide chain.

[0017] The film guide driven sprocket assembly comprises a sprocket bearing seat and a film guide sprocket. The axle of the film guide sprocket is installed on the long frame via a bearing and the sprocket bearing seat; the film guide sprocket is connected to the film guide chain.

[0018] In the film guiding mechanism, the lower plane of the film guiding chain is used as the main working plane, which is lower than the lower plane of the long frame, the lower plane of the chain attached to the long frame, and the lower plane of the second conveyor chain, so that when the film frame on the horizontal wrapping packaging machine is rotated to the bottom of the long frame with the closed rotating ring, the PE stretch film contacts the lower plane of the film guiding chain and is tightly wrapped on the lower plane of the film guiding chain;

[0019] The film guide chain and chain bracket are installed on the outside of the long frame.

[0020] In the film guide mechanism, there is a chain bracket between the upper and lower sides of the film guide chain. The chain bracket is installed on the long frame and is located between the film guide active sprocket assembly and the film guide driven sprocket assembly; the chain bracket supports and limits the film guide chain.

[0021] In the film guiding mechanism, the chain bracket includes a chain support plate and a support plate bracket. The chain support plate is fixed on the upper and lower sides of the support plate bracket. The chain support plate is made of nylon material. The contact between the chain support plate and the film guiding chain has the effect of wear resistance and noise reduction.

[0022] In the film guiding mechanism, the transmission method is that the driving sprocket of the film guiding mechanism is meshed with the lower surface of the second transmission chain connecting the driving sprocket assembly and the driven sprocket assembly, and the driving sprocket of the film guiding mechanism is driven to rotate by the lower surface of the second transmission chain, and the rotation direction of the driving sprocket of the film guiding mechanism is opposite to the rotation direction of the sprocket on the driving sprocket assembly, so that the movement direction of the lower plane of the film guiding chain is consistent with the movement direction and speed of the working surface on the upper side of the attached chain plate chain, thereby achieving the effect of guiding the film forward.

[0023] In the film guiding mechanism, the heights of the rotating shafts of the film guiding active sprocket assembly and the film guiding driven sprocket assembly are lower than the heights of the rotating shafts of the active sprocket assembly and the driven sprocket assembly.

[0024] The sprockets and chains in this article can be replaced by pulleys and belts.

[0025] Working principle: The goods to be packaged are placed on the attached chain plate conveyor and move leftward along with the attached chain plate. The lower side of the film guiding chain of the film guiding mechanism moves leftward at the same conveying speed as the attached chain plate. When the goods to be packaged reach the closed rotating ring and move above the film guiding mechanism, the film roll makes a circular motion in the vertical direction along with the closed rotating ring, and the PE stretch film wraps the goods, the protruding part of the long frame, and the film guiding mechanism together. The goods move leftward along the upper side of the attached chain plate, and the lower PE stretch film moves leftward along the lower side of the film guiding chain. The PE stretch film can be smoothly exported to the left from the conveyor until the packaging of the goods is completed. The PE stretch film shortens under the action of elasticity. The chain bracket plays a role in supporting and limiting the film guiding chain, preventing the film guiding chain from shifting or bending under the influence of the tightening force of the PE stretch film.

[0026] The beneficial effects of the present invention are that the attached chain plate conveyor with a film guiding mechanism is used in cooperation with a horizontal winding packaging machine, and can be applied to goods with a U-shaped pallet, cushion blocks placed at the bottom, or a shorter length in the running direction of the conveyor. The device has a simple structure, is convenient to use and maintain, expands the application range of the horizontal winding packaging machine, is an effective supplement to the horizontal winding packaging machine, reduces the labor intensity of workers, saves the packaging cost of customers, improves work efficiency, and enhances the packaging effect of goods.

[0027] The protruding part of the long frame on the attached chain plate conveyor can pass through the closed rotating ring of the horizontal winding packaging machine and is arranged within the rotating packaging range of the film rack. Its front end is close to the rear end of the rear conveying line, which can enable the goods with a U-shaped pallet, cushion blocks placed at the bottom, or a shorter length in the running direction of the conveyor to smoothly transition and run.

[0028] The lower side of the film guiding chain in the film guiding mechanism is lower than the lower plane of the long frame and is within the rotating packaging range of the film rack. During operation, the stretch film contacts the lower plane of the film guiding chain, and the running direction of the lower side of the film guiding chain is the same as the running direction of the attached chain plate on the side carrying the goods (i.e., the upper side of the attached chain plate), which can enable the wound stretch film to be smoothly exported forward and avoid the breakage of the stretch film affecting the packaging effect.

[0029] The film guiding mechanism can adjust the number of teeth of the driving sprocket to keep the conveying speed of the film guiding chain consistent with that of the attached chain plate, ensuring the smooth export of the PE stretch film.

[0030] The film guiding mechanism is provided with a chain bracket, which plays a role in supporting and limiting the film guiding chain, preventing the film guiding chain from shifting under the influence of the tightening force of the PE stretch film, ensuring the normal operation of the film guiding chain, and enabling the PE stretch film to be smoothly exported.

[0043] The film guiding mechanism is installed at the protruding part of the front end of the long frame and is located within the rotating packaging range of the film frame 2 installed on the closed swivel 3. When the goods move forward while being wrapped with the packaging film, the film guiding mechanism smoothly moves the lower side of the packaging film forward and guides it out.

[0044] Four mutually parallel frames are installed above the legs 5 , the protruding parts of the front ends of the two middle long frames 9 pass through the closed swivel 3 of the horizontal wrapping packaging machine 1 , and the two short frames 10 are on both sides.

[0045] The conveying mechanism adopts an attached chain plate chain sprocket assembly; a set of attached chain plate chain sprocket assemblies is installed between the two ends of each long frame 9 and between the two ends of each short frame 10, and each attached chain plate chain runs forward synchronously to convey the goods forward; the attached chain plate chain sprocket assembly is connected to the drive motor 6 through a transmission device.

[0046] In the conveying mechanism, the transmission device includes a driving sprocket assembly 11 and a driven sprocket assembly 13 mounted on the frame;

[0047] A first transmission sprocket 23 and a second transmission sprocket 24 are fixedly mounted on the first transmission shaft 22 in the driving sprocket assembly 11, and a driving sprocket 25 of the chain plate chain sprocket assembly on the short frame is also mounted on the first transmission shaft 22;

[0048] The driving motor 6 is installed on the supporting leg 5 and connected to the first transmission sprocket 23 and the first transmission shaft 22 in the driving sprocket assembly 11 through the first transmission chain 19. The driving sprocket assembly 11 is driven to rotate by the driving motor 6, and then the chain plate attached chain 7 on the short frame 10 is driven to move to transport the goods.

[0049] A third transmission sprocket 27 is fixedly mounted on the second transmission shaft 26 in the driven sprocket assembly 13, and a driving sprocket 28 of the chain plate chain sprocket assembly on the long frame 9 is also mounted on the second transmission shaft 26; the driven sprocket assembly 13 is mounted on the front end of the long frame 9;

[0050] The second transmission sprocket 24 in the driving sprocket assembly 11 is connected to the third transmission sprocket 27 in the driven sprocket assembly 13 through the second transmission chain 20; the driven sprocket assembly 13 is connected to the attached chain plate chain 7 on the long frame 9 and drives it to move forward, and transports the goods forward together with the attached chain plate chain 7 on the short frame 10.

[0051] The film guiding mechanism includes a film guiding driving sprocket assembly 14, a film guiding driven sprocket assembly 17, and a film guiding chain 18 connected therebetween;

[0052] The film guide driving sprocket assembly 14 includes a film guide mechanism driving sprocket 15, a film guide transmission shaft 29, and a film guide sprocket 30 which are connected in sequence. The transmission shaft 29 is installed on the long frame via a seat bearing; the film guide sprocket is connected to the film guide chain 18;

[0053] The film guide driven sprocket assembly 17 comprises a sprocket bearing seat and a film guide sprocket 30. The axle of the film guide sprocket is installed on the long frame via the bearing and the sprocket bearing seat; the film guide sprocket is connected to the film guide chain.

[0054] In the film guiding mechanism, the lower plane of the film guiding chain 18 serves as the main working plane, which is lower than the lower plane of the long frame 9, the lower plane of the attached chain plate chain 7 on the long frame, and the lower plane of the second conveyor chain. When the film frame 2 on the horizontal wrapping packaging machine 1 is rotated to the bottom of the long frame 9 along with the closed swivel 3, the PE stretch film contacts the lower plane of the film guiding chain 18 and is tightly wrapped around the lower plane of the film guiding chain 18.

[0055] In the film guiding mechanism, there is a chain bracket 16 between the upper and lower sides of the film guiding chain. The chain bracket is installed on the long frame 9 and is located between the film guiding active sprocket assembly 14 and the film guiding driven sprocket assembly 17; the chain bracket supports and limits the film guiding chain 18.

[0056] In the film guiding mechanism, the chain bracket 16 includes a chain support plate and a support plate bracket. The chain support plate is fixed on the upper and lower sides of the support plate bracket. The chain support plate is made of nylon material. The chain support plate is in contact with the film guiding chain 18, which has the effect of wear resistance and noise reduction.

[0057] In the film guiding mechanism, the transmission method is that the active sprocket 15 of the film guiding mechanism is meshed with the lower surface of the second transmission chain 20 connecting the active sprocket assembly 11 and the driven sprocket assembly 13, and the active sprocket 15 of the film guiding mechanism is driven to rotate by the lower surface of the second transmission chain 20, and the rotation direction of the active sprocket 15 of the film guiding mechanism is opposite to the rotation direction of the sprocket on the active sprocket assembly 11, so that the movement direction of the lower plane of the film guiding chain 18 is consistent with the movement direction and speed of the working surface on the upper side of the attached chain plate chain 7, thereby achieving the effect of guiding the film forward.

[0058] In the film guiding mechanism, the heights of the rotating shafts of the film guiding driving sprocket assembly 14 and the film guiding driven sprocket assembly 17 are lower than the heights of the rotating shafts of the driving sprocket assembly 11 and the driven sprocket assembly 13 .

[0059] The chain plate conveyor 4 with attached chain plates mainly consists of legs 5, a long frame 9, a short frame 10, a driving motor 6, a driving sprocket assembly 11, a driven sprocket assembly 13, a transmission chain, a tensioning sprocket assembly 8, and the chain plate chain 7 with attached chain plates, etc. The legs 5 are installed on the ground as the support of the overall structure and the height is adjustable. The driving sprocket assembly 11, the driven sprocket assembly 13, and the tensioning sprocket assembly 8 are installed on the frame.

[0060] The film guiding mechanism 12 mainly consists of a film guiding driving sprocket assembly 14, a film guiding driven sprocket assembly 17, a film guiding chain 18, and a chain bracket 16, etc. The film guiding mechanism 12 is integrally installed on the protruding part at the front end of the long frame 9. The film guiding chain 18 and the chain bracket 16 are installed on the outside of the long frame.

[0061] Currently, the conveyor arrangement used in conjunction with the horizontal winding packaging machine 1 in the market is as Figure 1 shown. There is a certain gap between the two conveyor lines, and it is not suitable for winding and packaging goods with a tray in the shape of a "川" character, cushion blocks, or goods with a shorter length in the running direction of the conveyor at the bottom.

[0062] The chain plate conveyor 4 with attached chain plates and a film guiding mechanism used in conjunction with the horizontal winding packaging machine 1 of the present invention is arranged as Figure 2 、 Figure 3 shown. The long frame 9 passes through the enclosed rotating ring 3 installed on the horizontal winding packaging machine 1. The film guiding mechanism 12 is installed on the protruding part of the long frame 9 and is within the rotational packaging range of the film rack 2 installed on the enclosed rotating ring 3. When the horizontal winding packaging machine 1 is working, the goods to be packaged are placed on the chain plate conveyor 4 with attached chain plates and move along with the chain plate chain 7 towards Figure 2 the left direction in the figure. At this time, as Figure 7 shown, the driving motor 6 drives the driving sprocket assembly 11, and then drives the driven sprocket assembly 13 to rotate counterclockwise. The upper side of the chain plate chain 7 moves to the left. At the same time, the lower surface of the second transmission chain connecting the driving sprocket assembly 11 and the driven sprocket assembly 13 meshes with the film guiding mechanism driving sprocket 15 on the film guiding driving sprocket assembly 14 arranged below it, driving the film guiding driving sprocket assembly 14 to move clockwise. The lower side of the film guiding chain 18 moves to the left. The conveying speed of the film guiding chain 18 can be made the same as that of the chain plate chain 7 by adjusting the number of teeth of the sprockets. When the goods to be packaged pass through the enclosed rotating ring 3 and run above the film guiding mechanism 12, the film rack 2 makes a circular motion in the vertical direction along with the enclosed rotating ring 3, as Figure 4The lower part of the shown PE stretching film contacts the lower side of the film guiding chain 18, and the upper part contacts the goods. The PE stretching film wraps the goods, the protruding part of the long frame, and the film guiding mechanism together. The goods move leftward along the upper side of the attached chain plate chain 7, and the lower PE stretching film moves leftward along the lower side of the film guiding chain 18. The PE stretching film can be smoothly led out of the conveyor to the left until the packaging of the goods is completed. The previously stretched PE stretching film shortens under the action of elasticity and tightly wraps the goods. The chain bracket 16 plays a role in supporting and limiting the film guiding chain 18 to prevent the film guiding chain 18 from shifting or bending under the influence of the tightening force of the PE stretching film. The left end of the goods runs onto another conveyor on the left side of the horizontal winding packaging machine.

[0063] A film clamping mechanism, a film welding mechanism, and a film cutting mechanism 31 are installed on the top of the horizontal winding packaging machine. The film clamping mechanism initially clamps the film head of the film roll on the film rack. The rotating ring of the packaging machine drives the film roll to rotate around the goods and wind the PE film 32. After winding several turns, the film clamping mechanism releases the film head. After the goods are wound with the PE film, the film welding mechanism welds the film tail to the PE film wound on the goods. The film clamping mechanism clamps the part of the film tail connected to the film roll, and the film cutting mechanism cuts or burns the film tail and the film roll, and the broken end of the film roll forms a film head that is still clamped on the film clamping mechanism. When starting to package the next goods, the film head is still clamped on the film clamping mechanism.

[0064] The attached chain plate chain conveyor with a film guiding mechanism used in cooperation with the horizontal winding packaging machine of the present invention includes an attached chain plate chain conveyor and a film guiding mechanism installed thereon. The protruding part of the long frame and the film guiding mechanism installed thereon can pass through the closed rotating ring of the horizontal winding packaging machine and are arranged within the rotating packaging range of the film rack, enabling the horizontal winding packaging machine to work properly and smoothly lead out the PE stretching film. The front end of the protruding part of the long frame of the attached chain plate chain conveyor is close to the rear end of the rear conveying line, enabling the goods placed at the bottom with a tray in the shape of the Chinese character "chuan", cushion blocks, or shorter in the running direction length of the conveyor to smoothly transition and be wound and packaged by the horizontal winding packaging machine, expanding the application range of the horizontal winding packaging machine and being an effective supplement to the horizontal winding packaging machine.
