Description

Technical Field

[0001] This utility model belongs to the technical field of slicing machines, specifically relating to a pusher plate counterweight device and a slicing machine pusher equipment. Background Technology

[0002] In the cigarette slicing workshop of a cigarette factory, the pusher plate of the slicing machine conveys materials via a toothed belt. Since the conveying direction of the cigarette blocks is inclined upwards, the installation positions of the toothed belt and the pusher plate are also inclined. When the pusher plate is not working, the toothed belt is subjected to a large traction force, and the large weight of the pusher plate itself causes an imbalance of forces. Long-term operation of the pushing process can easily cause the toothed belt to break. Utility Model Content

[0003] The purpose of this utility model is to provide a pusher plate counterweight device and a slicing machine pusher equipment to solve the problem that the toothed belt that drives the pusher plate in the existing slicing machine is prone to breakage when not in operation due to excessive traction force.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] In a first aspect, a pusher plate counterweight device is provided for counterweighting the pusher plate in a slicer, comprising a sprocket, a chain, and a counterweight assembly; the sprocket is rotatably mounted on the slicer via a sprocket shaft, one end of the chain is connected to the pusher plate, and the other end of the chain is connected to the counterweight assembly; a speed regulating assembly is installed on the slicer, and the speed regulating assembly is drivenly connected to the sprocket shaft to control the speed of the sprocket.

[0006] In this invention, the conveyor belt of the slicing machine is inclined upwards to transport materials (such as tobacco blocks), employing a step-by-step conveying method to facilitate slicing of the material by the slicing machine's cutter at the end of the conveyor. When the pusher plate is not in operation, it is in an inclined state, resulting in a downward traction force on the toothed belt, which can easily lead to breakage of the toothed belt over prolonged periods. The counterweight assembly provides a balancing pull on the pusher plate via a chain, while the sprocket acts as a reversing mechanism. This design ensures that the traction force on the toothed belt is reduced or eliminated, thereby extending the service life of the toothed belt. Simultaneously, during the material pushing process by the pusher plate, the counterweight assembly also protects the toothed belt through the same balancing effect.

[0007] Further defined: the speed adjustment assembly includes a mounting bracket, a transmission component, and a brake caliper. The sprocket shaft is mounted on the mounting bracket via bearings. A brake disc is mounted in the middle of the sprocket shaft. The brake caliper is mounted on the mounting bracket via a connecting shaft and is opposite to the brake disc. The sprocket is mounted on one end of the sprocket shaft, and the transmission component is mounted on the other end of the sprocket shaft. A traction control component connected to the brake caliper is rotatably mounted on the end of the connecting shaft near the transmission component. The rotation of the sprocket intermittently drives the traction control component to rotate through the transmission component. The rotation of the traction control component pulls the brake caliper into frictional contact with the brake disc.

[0008] In this system, regardless of whether the sprocket rotates forward or backward, power can be transmitted to the traction control component through the transmission component. Furthermore, the faster the sprocket rotates, the greater the frequency at which the transmission component intermittently drives the traction control component, and consequently, the more times the traction control component applies braking traction to the brake caliper, and the more times the brake caliper applies intermittent braking to the brake disc.

[0009] Further defined: the transmission component includes a timing disc fixedly mounted on the sprocket shaft and a rotating sleeve rotatably mounted on the connecting shaft; the outer circumferential surface of the timing disc has at least one connecting screw hole, and at least one of the connecting screw holes is fitted with a lever; a passive dial coupled to the lever is mounted on the rotating sleeve, and the traction control component is mounted on the end of the rotating sleeve away from the passive dial.

[0010] When there are multiple connecting screw holes, the interval time of the synchronous disc can be adjusted by adding or removing levers, thereby adjusting the frequency of the driven disc rotation. On the other hand, the synchronous disc can also be counterweighted to make its structure more balanced and to make the synchronous disc and sprocket more balanced at both ends of the sprocket shaft.

[0011] Further defined: the traction control component includes an actuating disc, a traction rope, and a traction disc. The actuating disc is fixedly connected to the rotating sleeve, and the traction disc is rotatably mounted on the connecting shaft. The traction disc and the actuating disc are coaxially spaced apart, and the surfaces of the traction disc and the actuating disc facing each other are provided with protrusions in a circumferential array. The traction rope connects the traction disc to the brake caliper.

[0012] Further defined: the connecting shaft includes a polygonal column section and a cylindrical section, the brake caliper is mounted on the polygonal column section, and the traction control component is mounted on the cylindrical section.

[0013] Further defined: the brake caliper includes a fixed frame fixedly mounted on the mounting bracket or the connecting shaft, and two sub-calipers slidably mounted on the fixed frame; the two sub-calipers are slidably connected to the connecting shaft and are respectively located on both sides of the brake disc; a spring is connected between the two sub-calipers.

[0014] The spring prevents the sub-caliper from contacting the brake disc when not being pulled, and the spring, in conjunction with the traction rope, provides better flexibility for the sub-caliper's movement.

[0015] Further, the fixing frame is provided with a sliding groove, and the top of the sub-caliper is connected to a sliding block that slides in cooperation with the sliding groove.

[0016] Further specifying: the speed adjustment component includes a damper, which is disposed between the sprocket shaft and the slicer.

[0017] Secondly, a slicing machine pushing device includes a frame, a pushing plate, and a pushing plate counterweight device as described above; a conveyor belt for conveying materials is inclinedly installed on the frame, and a toothed belt is installed in the middle of the frame; a guide is provided in the middle of the frame, the pushing plate overlaps the guide and is fixedly connected to one section of the toothed belt; the pushing plate counterweight device is connected to the pushing plate and serves as a counterweight for the pushing plate.

[0018] This design allows for the use of a counterweight device to balance the weight of the pusher plate, thereby protecting the toothed belt that drives the pusher plate and preventing unbalanced forces on the toothed belt.

[0019] Further defined: the pusher plate includes at least a pusher plate mounting frame and a pusher plate body rotatably mounted on the pusher plate mounting frame.

[0020] The utility model adopting the above technical solution has the following advantages:

[0021] In this application, one end of the chain is connected to the pusher plate, and the other end passes around the sprocket and is connected to a counterweight assembly, which provides weight to the pusher plate. When the pusher plate is not in operation, it exerts a large traction force on the toothed belt connected to it. This traction force is balanced by the tension provided by the counterweight assembly, solving the problem that the toothed belt driving the pusher plate in the slicer is prone to breakage due to excessive traction when not in operation. In addition, the counterweight of the counterweight assembly can be increased or decreased, thus better adapting to different feeding speeds of the pusher plate. Through the set speed adjustment component, a certain braking force can be provided under the drive of the sprocket itself to prevent the sprocket speed from exceeding the limit. The purely mechanical structure design has high reliability of adjustment; and the overall structure is simple, low in cost, and highly practical. Attached Figure Description

[0034] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0035] Example 1

[0036] like Figures 1-4 As shown in the figure, a pusher plate counterweight device 500 of this utility model is used for counterweighting the pusher plate in a slicer. It includes a sprocket 502, a chain, and a counterweight assembly 505; wherein the counterweight assembly 505 is a weight. The sprocket 502 is rotatably mounted on the slicer via a sprocket shaft 508. The rotatable mounting of the sprocket shaft 508 can be achieved by a bearing installed on a mounting bracket 507 located on the slicer. One end of the chain is connected to the pusher plate 400, and the other end of the chain is connected to the counterweight assembly 505. A speed regulating assembly is installed on the slicer, and the speed regulating assembly is drivenly connected to the sprocket shaft 508 to control the speed of the sprocket 502.

[0037] In this embodiment, the counterweight pulls the chain vertically downwards. This allows for the installation of an intermediate sprocket on the slicer, which guides the chain's direction of movement and prevents interference with other operations of the slicer. The weight of the counterweight can be determined based on actual conditions; for example, the unidirectional traction force of the toothed belt 320 on the pusher plate can be calculated, and the weight of the counterweight can be determined after calculating the unidirectional traction force. When the pusher plate is not in operation and is in an inclined state, the counterweight can counteract the traction force of the pusher plate on the toothed belt 320, preventing the pusher plate from causing the toothed belt 320 to break. This extends the service life of the toothed belt 320, reduces production costs, and improves production efficiency. Simultaneously, during the material pushing process, the counterweight component 505 can also reduce the driving energy consumption of the toothed belt 320 by pulling the pusher plate in conjunction with the toothed belt 320, while maintaining a balance of traction force and protecting the toothed belt 320.

[0038] In this embodiment, the chain head 501 and chain tail 503 can be connected to the pusher plate and counterweight by welding; the chain tail 503 can be connected to a hook 504, through which the counterweight can be added or removed for counterweight adjustment; the chain head 501 can be connected to the lug 408 via a pull rod 506. Two sets of counterweights can be provided, located on opposite sides of the slicer.

[0039] like Figures 6-9As shown, in this embodiment, the speed adjustment assembly includes a mounting bracket 507, a transmission component, and a brake caliper. A sprocket shaft 508 is mounted on the mounting bracket 507 via bearings. A brake disc 509 is mounted in the middle of the sprocket shaft 508. The brake caliper is mounted on the mounting bracket 507 via a connecting shaft 512 and is opposite to the brake disc 509. The connecting shaft 512 includes a polygonal cylindrical section and a cylindrical section. The brake caliper is mounted on the polygonal cylindrical section, and the traction control component is mounted on the cylindrical section. A sprocket is mounted at one end of the sprocket shaft 508, and a transmission component is mounted at the other end of the sprocket shaft 508. The transmission component includes a timing disc 510 fixedly mounted on the sprocket shaft 508 and a rotating sleeve 513 rotatably mounted on the connecting shaft 512. The outer circumferential surface of the timing disc 510 has three connecting screw holes, and a lever 511 is installed in each of the three connecting screw holes. A passive dial 514 coupled to the lever 511 is mounted on the rotating sleeve 513. When the timing disc 510 rotates, the passive dial 514 can be rotated by the lever 511. A traction control component connected to the brake caliper is rotatably mounted on one end of the connecting shaft 512 near the transmission component. The rotation of the sprocket intermittently drives the traction control component to rotate through the transmission component. The rotation of the traction control component pulls the brake caliper into frictional contact with the brake disc 509.

[0040] In fact, the number of connecting screw holes in this embodiment can also be other numbers, either odd or even. Furthermore, the passive dial 514 has three paddles, making it an eccentric structure with two paddles always positioned below the axis of the rotating sleeve 513, thus providing a return function. If the driven speed of the passive dial 514 is too low, it will not rotate for the entire rotation cycle and will not drive the traction control component. The two paddles being positioned below the axis of the rotating sleeve 513 also ensures that the lever 511 can contact the paddles. Adjusting the lever 511 and the passive dial 514 allows for adjustment of the intermittent time of the synchronizer disc 510 and the number of times the traction control component pulls the brake caliper.

[0041] In this embodiment, the traction control component includes an actuation disc 520, a traction rope 522, and a traction disc 519. The actuation disc 520 is fixedly connected to the rotating sleeve 513. The traction disc 519 is rotatably mounted on the connecting shaft 512. The traction disc 519 and the actuation disc 520 are coaxially spaced apart. The surfaces of the traction disc 519 and the actuation disc 520 facing each other are provided with protrusions 521 in a circumferential array. The number of protrusions 521 on the traction disc 519 and the actuation disc 520 is different. The traction rope 522 connects the traction disc 519 to the brake caliper.

[0042] In practice, the traction rope 522 connects to the traction disc 519 at the outer top. When the traction disc 519 is not driven, the traction of the traction rope 522 keeps the traction disc 519 in a fixed position. The traction rope 522 can be made of rubber material, elastically connecting to the traction disc 519. When the traction disc 519 rotates very little, it is insufficient to drive the brake caliper to brake. The number of protrusions 521 in this embodiment can also be increased or decreased as needed; a shoulder 518 can be provided on the connecting shaft 512 to relatively limit the position of the traction disc 519.

[0043] In this embodiment, the traction control mechanism operates as follows: during traction, regardless of whether the sprocket 502 rotates forward or backward, the power of the sprocket 502 is transmitted to the rotating sleeve 513 and the actuating disc 520 of the traction control mechanism via the synchronous disc 510 and the driven dial 514 of the transmission component. The protrusion 521 on the actuating disc 520 pushes the protrusion 521 on the traction disc to rotate, and the rotation is transmitted to the traction disc 519, which in turn pulls the traction rope 522. The traction rope 522 then pulls the brake caliper to achieve braking. Furthermore, the faster the sprocket rotates, the higher the frequency at which the synchronous disc 510 and the driven dial 514 in the transmission component intermittently drive the actuating disc 520. Consequently, the number of braking tractions applied to the brake caliper via the actuating disc 520, the traction disc 519, and the traction rope 522 is increased, and the number of times the brake caliper applies intermittent braking to the brake disc 509 is increased. When the sprocket rotates at a lower speed, it indirectly prevents the sprocket speed from exceeding the limit.

[0044] In fact, in this embodiment, when there are two, four or five connecting screw holes, on the one hand, the interval time of the synchronization disc 510 can be adjusted by adding or removing levers 511, thereby adjusting the frequency of the driven passive dial 514 to rotate; on the other hand, the synchronization disc 510 can be counterweighted to make the structure of the synchronization disc 510 more balanced, and to make the synchronization disc 510 and the sprocket more balanced at both ends of the sprocket shaft 508.

[0045] like Figure 8 , Figure 9As shown, in this embodiment, the brake caliper includes a fixed frame 515 fixedly mounted on the mounting bracket 507, and two sub-calipers slidably mounted on the fixed frame 515; a spring 525 connects the two sub-calipers; the fixed frame 515 is a U-shaped frame with fixing holes, and the U-shaped frame is mounted on the slicer by fixing bolts passing through the fixing holes. The two sub-calipers are a left sub-caliper 516 and a right sub-caliper 517, which are slidably connected to the connecting shaft 512. The left sub-caliper 516 is located on the left side of the brake disc 509, and the right sub-caliper 517 is located on the right side of the brake disc 509. When the traction rope 522 is not under tension, the spring 525 prevents the left caliper 516 and right caliper 517 from contacting the brake disc 509. However, when the traction rope 522 is under tension, the spring force overcomes the spring force of the spring 525, causing the left caliper 516 and right caliper 517 to contact the brake disc 509 for braking. This structural design provides high braking flexibility; specifically, the spring 525 prevents the calipers from contacting the brake disc 509 when not under tension, and the spring 525, in conjunction with the traction rope 522, provides better flexibility for the movement of the calipers.

[0046] In fact, the fixing bracket 515 in this embodiment can also be installed on the connecting shaft 512, and then the left sub-caliper 516 and the right sub-caliper 517 can be assembled and adjusted accordingly.

[0047] like Figure 9 As shown, in this embodiment, the fixing frame 515 has a sliding groove 523, and the top of the sub-clamp is connected to a sliding block 524 that slides in conjunction with the sliding groove 523. A through hole is provided at the bottom of the fixing frame 515, through which the traction rope 522 can pass. A limit screw is provided at the end of the sliding groove 523 to prevent the sub-clamp from coming out.

[0048] In this embodiment, the speed adjustment component includes a damper, which is disposed between the sprocket shaft 508 and the slicer; wherein, the damper provides a damping, so that when the speed of the sprocket is too high, the sprocket shaft 508 is damped to prevent the sprocket speed from being too high.

[0049] Example 2

[0050] This embodiment of a slicing machine pushing device includes a frame 100, a pushing plate 400, and a pushing plate counterweight device 500. A conveyor belt 200 for conveying materials is inclinedly installed on the frame 100. A first motor 210 is installed on the frame 100. The output shaft of the first motor 210 can be connected to the pulley of the conveyor belt 200 through a reducer to drive the conveyor belt 200 to convey smoke blocks. A gear 330 is installed in the middle of the frame 100. A toothed belt 320 parallel to the conveyor belt 200 is wound around the gear 330. A second motor 310 is installed on the frame 100. The second motor 310 is used to drive the gear 330 and the toothed belt 320. The gear 330 and the toothed belt 320 constitute the pushing plate driving device 300. A guide member is provided in the middle of the frame 100. The pusher plate 400 overlaps the guide member and is fixedly connected to a section of the toothed belt 320 through a connecting block 411. The pusher plate counterweight device 500 is connected to the pusher plate 400 to provide counterweight for the pusher plate 400. The guide member includes a guide rail 413 connected to the frame 100 and a guide seat 412 in contact with the guide rail 413. The guide seat 412 is fixedly connected to the pusher plate 400 to guide the movement of the pusher plate 400. This structural design allows the pusher plate 400 to be counterweighted by the pusher plate counterweight device 500, thereby protecting the toothed belt 320 that drives the pusher plate 400 and preventing unbalanced forces on the toothed belt 320. In particular, it reduces the traction force required on the pusher plate 400 when the toothed belt 320 is not in operation.

[0051] like Figures 3-5 As shown, in this embodiment, the pusher plate 400 includes at least a pusher plate mounting frame 401 and a pusher plate body 402 rotatably mounted on the pusher plate mounting frame 401. The pusher plate mounting frame 401 includes a connecting plate 403, two side plates 405 connected to both ends of the connecting plate 403, and a bottom plate 404 parallel to the connecting plate 403 and located between the two side plates 405. A guide seat 412 is mounted on the top outer edge of the side plates 405. A hook 408 is mounted in the middle of the connecting plate 403, and the hook 408 is connected to a chain via a pull rod 506. Two extension plates 406 are connected to the connecting plate 403. The extension plates 406 have mounting holes 407 for mounting the pusher plate body 402. The pusher plate body 402 can rotate in the mounting holes 407. An air rod is installed on the base plate 404. The free end of the air rod is connected to the outer wall of the pusher plate body 402. The air rod can drive the pusher plate body 402 to rotate relative to the extension plates 406 to achieve contact during pushing and avoidance of smoke block conveying.

[0052] This structural design uses a counterweight component 505 to counterweight the pusher plate. When the pusher plate is not in operation, it exerts a significant traction force on the toothed belt 320 connected to it. This traction force is balanced by the tension provided by the counterweight component 505, solving the problem of the toothed belt 320 driving the pusher plate in the slicer easily breaking due to excessive traction when not in operation. Furthermore, the counterweight of the counterweight component 505 can be increased or decreased, thus better adapting to different feeding speeds of the pusher plate. The speed adjustment component provides a certain braking force under the drive of the sprocket itself, preventing the sprocket speed from exceeding its limit. The purely mechanical structure design ensures high reliability of adjustment; moreover, the overall structure is simple and highly practical.

[0053] The above provides a detailed description of the pusher plate counterweight device and the slicing machine pusher equipment provided by this utility model. The specific embodiments are described only to help understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
