Description

Technical Field

[0001] This application relates to the field of tobacco processing, and more particularly to a chain conveyor installation auxiliary device. Background Technology

[0002] The stem cutter is a key piece of equipment in the tobacco processing industry for handling tobacco stems. Its copper busbar chain, as a core component, plays a crucial role in conveying and compacting the stems. During long-term operation, oil and soot easily accumulate at the hinge points of the copper busbar chain, leading to stiffness and poor transmission, requiring regular disassembly for deep cleaning and maintenance. However, the installation process of the copper busbar chain in existing technology has significant drawbacks: the component is heavy and complex, requiring multiple operators to work together to lift, position, and adjust it manually. This traditional manual installation method is not only labor-intensive and time-consuming but also poses safety hazards due to operator errors. Furthermore, excessive manpower increases maintenance costs. Especially under conditions of frequent disassembly and cleaning, the inefficient installation method severely restricts equipment maintenance efficiency and affects production continuity. Utility Model Content

[0003] In view of this, the purpose of this application is to overcome the shortcomings of the prior art and provide a chain installation auxiliary device.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0005] This application provides:

[0006] A chain conveyor installation auxiliary device, comprising:

[0007] A slide rail frame, the slide rail frame having a guide surface;

[0008] The support frame is located on the side of the slide rail frame closer to the stalk cutter;

[0009] A guide roller, which is rotatably mounted on the support frame;

[0010] A traction chain is placed on the guide surface, with one end of the traction chain connected to the old chain and the other end of the traction chain away from the old chain connected to the new chain.

[0011] Furthermore, the slide rail bracket includes:

[0012] Frame, the frame having installation space;

[0013] A rotating roller is rotatably mounted at both ends of the frame and is located within the mounting space.

[0014] At least one support plate is fixedly connected to the frame and is located between the two rotating rollers. The circumferential surface of the rotating rollers and the surface of the support plate form a guide surface.

[0015] Furthermore, the support plate has multiple weight-reduction holes extending through it.

[0016] Furthermore, the frame includes two spaced-apart base rods, forming the installation space between the two base rods. An inclined rod is fixedly installed at one end of each base rod, and the inclined rod is inclined. The base rod and the inclined rod form a preset angle. A support rod is installed at the end of the base rod away from the connection point with the inclined rod, and the end of the support rod away from the base rod is fixedly connected to the inclined rod.

[0017] Furthermore, at least one fixing hole is provided through the bottom rod, and a buckle is provided on one side of the fixing hole.

[0018] Furthermore, connecting pieces are provided at both ends of the rotating shaft of the guide roller, and connecting frames are fixedly installed on the connecting pieces. The connecting frames are used to fix the guide roller, and a limit sleeve is also provided on the outer circumferential surface of the guide roller.

[0019] Furthermore, the connecting frame includes a connecting rod connected to the connecting piece, a fixing rod is fixedly installed at the end of the connecting rod away from the connecting piece, and fixing pieces are fixedly provided at both ends of the fixing rod.

[0020] Furthermore, a connecting hole is provided through the connecting piece, and a thread is provided on the circumferential surface of the connecting rod. The connecting rod passes through the connecting hole, and a first nut and a second nut are installed on the connecting rod. The first nut and the second nut are respectively located on both sides of the connecting piece.

[0021] Furthermore, the traction chain has multiple links, each link including a link member. One end of the link member is provided with a first protrusion, and the first protrusion has a first through hole in a first direction, through which a first pin passes. At least one second protrusion is provided at the end of the link member away from the first protrusion, and the second protrusion has a second through hole in a first direction, through which a second pin passes.

[0022] Furthermore, the chain mounting auxiliary device also includes a base for supporting the slide rail frame. The base includes a carrier plate, a carrier frame is fixedly installed at the bottom of the carrier plate, and fasteners are fixedly provided on the upper surface of the carrier plate.

[0023] This application utilizes the guide surface of the slide rail frame and the traction chain to form a continuous conveying channel. The old chain itself powers the new chain via the traction chain, which then slides synchronously along the guide surface and guide rollers of the slide rail frame into the cutting machine. This effectively solves the problems of high labor intensity and low efficiency caused by manually lifting the chain. The combined structure of the support frame and guide rollers forms a stable guiding fulcrum on the cutting machine side, preventing the chain from falling and jamming, significantly reducing safety risks during installation. The mechanical transmission design of the slide rail frame and traction chain allows the replacement of the old and new chains to be completed in a single operation, simplifying the traditional multi-person collaborative process to a single-person monitoring operation, greatly shortening maintenance time and reducing labor costs.

[0039] When replacing the copper chain of the existing stem cutting machine (hereinafter referred to as the chain), it is usually done by manually lifting it. Since the chain is heavy, it is inefficient and dangerous to replace it entirely by manual labor.

[0040] This application provides a chain installation auxiliary device, including a slide rail frame 100, a support frame 200, a guide roller 300, and a traction chain 400. Specifically, the slide rail frame 100 has a guide surface, the support frame 200 is located on the side of the slide rail frame 100 closer to the stalk cutter, the guide roller 300 is rotatably mounted on the support frame 200, the traction chain 400 is placed on the guide surface, one end of the traction chain 400 is connected to the old chain, and the other end of the traction chain 400 away from the old chain is connected to the new chain.

[0041] See Figure 1As shown, when the chain in the stem cutter needs to be replaced, firstly, one end of the traction chain 400 is connected to the old chain in the stem cutter. Then, the end of the traction chain 400 away from the old chain is connected to the new chain to be replaced. The lower half of the old chain is discharged outwards by the guide roller 300. Specifically, the power of the stem cutter drives the old chain to rotate gradually, and the lower half of the old chain is gradually discharged outwards by the guide roller 300. As the upper half of the old chain rotates, it drives the traction chain 400 into the stem cutter, which in turn drives the chain to rotate. The new chain connected by the traction chain 400 enters the cutting machine. As the cutting machine drives the old chain to continue rotating and being discharged outward, the new chain will be fully inserted into the cutting machine under the transmission traction of the traction chain 400. After the new chain enters the cutting machine, it will be installed with the drive shaft of the cutting machine. At this time, the cutting machine can move the new chain. As the cutting machine drives the new chain to move, the new chain will be installed in the predetermined position. After the new chain is fully inserted into the cutting machine, the old chain and the traction chain 400 will be discharged at the position of the guide roller 300, thus completing the replacement of the old and new chains.

[0042] In this embodiment, since the lower half of the old chain will fall under the action of gravity, it will cause scraping with the body of the cutting machine, causing the chain to arch and jam. Therefore, this application guides it with guide roller 300 to prevent it from jamming during rotation.

[0043] It should be noted that when the lower half of the old chain is discharged under the guidance of the guide roller 300, manual assistance is still required to pull it outward to prevent the lower half of the old chain from accumulating at the position of the guide roller 300 and causing jamming.

[0044] In this embodiment, the slide rail frame 100 mainly supports and guides the traction chain 400 and the new chain. Specifically, the guide surface of the slide rail frame 100 is an inclined surface. The traction chain 400 and the new chain slide on the guide surface and enter the cutting machine to achieve installation.

[0045] The slide rail frame 100 includes a frame 110, a rotating roller 120, and at least one support plate 130. The frame 110 has an installation space 101. The rotating roller 120 is rotatably mounted at both ends of the frame 110 and is located within the installation space 101. The support plate 130 is fixedly connected to the frame 110 and is located between the two rotating rollers 120. The circumferential surface of the rotating roller 120 and the surface of the support plate 130 form a guide surface.

[0046] Please see Figure 1 and Figure 2As shown, in order to enable the new chain and traction chain 400 to smoothly enter the stalk cutter, a frame 110 is set at the chain replacement port of the stalk cutter. Rotating rollers 120 are installed at both ends of the frame 110, thereby reducing the force required for the new chain and traction chain 400 to enter the stalk cutter, and to a certain extent reducing the wear of the traction chain 400 and the new chain. Since there is a certain gap between the two rotating rollers 120, the traction chain 400 and the new chain are prone to fall off in the gap between the two rotating rollers 120 when passing through the two rotating rollers 120. Therefore, a support plate 130 needs to be installed in the gap area between the two rotating rollers 120 to provide support. Specifically, in this embodiment, multiple spaced support plates 130 are provided in the gap between the two rotating rollers 120. At this time, the upper surface of the support plate 130 and the circumferential surface of the two rotating rollers 120 form a guide surface for the traction chain 400 and the new chain to pass through.

[0047] In this embodiment, since the replacement port of the chain of the stalk cutter has a certain height, the upper surface of the frame 110 is inclined, and the corresponding guide surface is also inclined, so as to facilitate the traction chain 400 and the new chain to enter the stalk cutter under the action of the guide surface.

[0048] Please continue reading. Figure 1 As shown, in order to further reduce the weight of the entire slide rail frame 100, a plurality of weight-reducing holes 131 are provided through the support plate 130. The weight of the entire slide rail frame 100 is reduced by the weight-reducing holes 131, thereby facilitating the handling and movement of the slide rail frame 100.

[0049] In this embodiment, the support plate 130 is rectangular, so the multiple weight-reducing holes 131 can be distributed rectangularly at equal intervals on the support plate 130.

[0050] The frame 110 includes two spaced-apart base rods 111, forming an installation space 101 between the two base rods 111. An inclined rod 112 is fixedly installed at one end of each base rod 111. The inclined rod 112 is inclined, and the base rod 111 and the inclined rod 112 form a preset angle. A support rod 113 is installed at the end of the base rod 111 away from the connection with the inclined rod 112. The end of the support rod 113 away from the base rod 111 is fixedly connected to the inclined rod 112.

[0051] Please continue reading. Figure 2As shown, the slide rail frame 100 has two spaced-apart frame bodies 110, which are fixedly connected and form an installation space 101 between them. From the side, the frame body 110 is triangular. Specifically, the frame body 110 includes a bottom frame body 110, which is horizontally set. The tilting rod 112 is tilted, and the support rod 113 is vertically set. The three are connected to each other to form a frame with a right-angled triangle shape on the side, providing a framework for the installation of the rotating roller 120 and the support plate 130, as well as supporting the traction chain 400 and the new chain passing through.

[0052] The guide roller 300 has connecting pieces 310 at both ends of its rotating shaft. A connecting frame 500 is fixedly installed on the connecting piece 310. The connecting frame 500 is used to fix the guide roller 300. A limit sleeve 320 is also provided on the outer circumference of the guide roller 300.

[0053] The connecting frame 500 includes a connecting rod 510 connected to the connecting piece 310. A fixing rod 520 is fixedly installed at the end of the connecting rod 510 away from the connecting piece 310. Fixing pieces 530 are fixedly provided at both ends of the fixing rod 520.

[0054] To prevent the old chain from falling and scraping against the machine platform during the discharge of the old chain and the installation of the new chain, a support frame 200 is installed on the machine platform of the cutting machine. At least one guide roller 300 is then installed on the support frame 200 to support the old chain during discharge and the new chain during installation.

[0055] Please see Figure 3 and Figure 4 As shown, in this embodiment, the guide roller 300 is rotatably mounted at the end of the support frame 200, and the guide roller 300 is located at the chain replacement port. Specifically, in order to prevent the old chain from deviating when it is discharged, limiting sleeves 320 are installed at both ends of the guide roller 300 to limit its width.

[0056] Please continue reading. Figure 3 and Figure 4 As shown, in order to prevent the guide roller 300 and the support frame 200 from moving, connecting plates 310 are provided at both ends of the guide roller 300, and connecting rods 510 are installed on the connecting plates 310. A fixing rod 520 is installed at the end of the connecting rod 510, and fixing plates 530 are also provided at both ends of the fixing rod 520 in the axial direction. When replacing the old chain, the fixing plates 530 can be fixedly installed on the cutting machine with bolts, thereby fixing the guide roller 300 and the support frame 200.

[0057] A connecting hole 311 is provided through the connecting piece 310, and a thread is provided on the circumference of the connecting rod 510. The connecting rod 510 passes through the connecting hole 311, and a first nut 511 and a second nut 512 are installed on the connecting rod 510. The first nut 511 and the second nut 512 are located on both sides of the connecting piece 310, respectively.

[0058] Please continue reading. Figure 3 and Figure 4 As shown, in order to adjust the height of the guide roller 300 to a predetermined height, a connecting hole 311 can be made on each connecting piece 310, and an external thread can be made on the outer circumferential surface of the connecting rod 510. The first nut 511 and the second nut 512 are screwed onto the connecting rod 510. The connecting rod 510 passes through the connecting hole 311. After the end of the support frame 200 is lifted so that the guide roller 300 reaches the predetermined height, the first nut 511 and the second nut 512 are screwed and tightened towards the connecting piece 310 to limit the height of the guide roller 300, thereby keeping the guide roller 300 at the predetermined height position. At this time, the support frame 200 may tilt to a certain extent, but it does not affect normal use.

[0059] In this embodiment, the guide roller 300 may be composed of a rotating shaft (not shown) and a rotating sleeve (not shown). The rotating sleeve is located on the outer periphery of the rotating shaft and can rotate relative to the rotating shaft. The connecting piece 310 is disposed on the rotating shaft, and the rotating shaft may be fixedly connected or rotatably connected to the support frame 200.

[0060] The traction chain 400 has multiple links, each link including a link member 410. One end of the link member 410 is provided with a first protrusion 420. The first protrusion 420 has a first through hole 421 extending through it in a first direction. A first pin 430 passes through the first through hole 421. At least one second protrusion 440 is provided at the end of the link member 410 away from the first protrusion 420. The second protrusion 440 has a second through hole 441 extending through it in a first direction. A second pin 450 passes through the second through hole 441.

[0061] See Figure 1 and Figure 5 As shown, the traction chain 400 is composed of several chain links. In this embodiment, in order to facilitate quick disassembly and installation with new and old chain rows, the traction chain 400 is composed of several single-row chain links.

[0062] In this embodiment, the first protrusion 420 can be connected to the old chain by inserting the first protrusion 420 into the groove of the old chain, and then inserting the first pin 430 into the old chain and extending it into the first through hole 421, thereby connecting the traction chain 400 to the old chain. Furthermore, when it is necessary to install and connect with a new chain, the second protrusion 440 can be inserted into the groove of the new chain, and then the second pin 450 can be inserted into the new chain and extending it into the second through hole 441, thereby connecting the second protrusion 440 to the new chain. Therefore, the traction chain 400 is connected to the old and new chains by the cooperation of the first pin 430 and the second pin 450.

[0063] In this embodiment, there are two second protrusions 440, and a connecting groove 411 is defined between the two second protrusions 440. The connecting groove 411 is adapted to connect with the protruding part of the new chain. It should be noted that the shape of the connecting groove 411 is adapted to the shape of the first protrusion 420.

[0064] In this embodiment, the first direction mentioned above is the width direction of the chain link 410.

[0065] At least one fixing hole 102 is provided through the bottom rod 111, and a buckle is provided on one side of the fixing hole 102.

[0066] The chain track installation auxiliary device also includes a base 600, which supports the slide rail frame 100. The base 600 includes a carrier plate 610, a carrier frame 620 is fixedly installed at the bottom of the carrier plate 610, and a fastener 630 is fixedly provided on the upper surface of the carrier plate 610. The fastener 630 is adapted to the shape of the fixing hole 102.

[0067] Please see Figure 1 and Figure 6 As shown, the existing chain replacement position of the stem cutter is relatively high, so the slide rail frame 100 cannot reach the corresponding height. Therefore, it is necessary to support the slide rail frame 100 by using the base 600. Specifically, the base 600 is mainly composed of a carrier plate 610 and a carrier frame 620. In order to fix the carrier plate 610 to the slide rail frame 100, multiple fasteners 630 are installed on the carrier plate 610, and fixing holes 102 that are compatible with the fasteners 630 are opened on the bottom rod 111. A buckle is fixedly installed on one side of each fixing hole 102. When the fastener 630 passes through the fixing hole 102 to the surface above the bottom rod 111, the fastener 630 is fixed by the buckle, thereby preventing the carrier plate 610 from separating from the slide rail frame 100.
