Description

Technical Field

[0001] This application relates to the field of slicing equipment, and more particularly to an automatic slicing and wrapping equipment. Background Technology

[0002] In the production and processing of energy storage temperature control units, plate heat exchangers are the core heat exchange components, and their performance is easily affected by ambient temperature. Therefore, it is usually necessary to wrap foam on the outer surface of the plate heat exchanger to achieve heat insulation effect.

[0003] Currently, most foam wrapping operations for plate heat exchangers in the industry rely on manual labor. Operators need to manually measure and cut foam strips of the corresponding specifications according to the actual length, width and height of the plate heat exchanger to be processed, then paste the foam strips on the outer surface of the plate heat exchanger, and manually wrap tape to reinforce the pasted foam strips.

[0004] However, the manual operation method results in a long processing time for foam wrapping of plate heat exchangers and low work efficiency, which needs to be improved. Summary of the Invention

[0005] To address the issue of low work efficiency, this application provides an automatic strip-cutting and wrapping device.

[0006] The automatic strip-cutting and wrapping equipment provided in this application adopts the following technical solution: An automatic strip cutting and wrapping device includes a working frame, a discharge roller, and a take-up roller. The discharge roller and the take-up roller are respectively located at both ends of the working frame along its length. The discharge roller is used to release foam, and the take-up roller is used to roll up waste material. The working frame is equipped with a cutting component. The side of the working frame is provided with a foam buffer station for collecting foam and a wrapping station for wrapping foam on a heat exchanger.

[0007] By adopting the above technical solution, after the foam is released by the discharge roller, it is continuously conveyed along its length on the work frame. When it passes the cutting component, the cutting component cuts multiple appropriately sized foam blocks from the entire foam strip. The cut waste is then rolled up by the receiving roller, ensuring continuous foam conveying. The cut foam blocks are placed in the buffer station for storage. The robotic arm at the wrapping station can pick up the foam from the buffer station and attach it to the surface of the plate heat exchanger, thereby achieving full automation from foam conveying, cutting to wrapping, and improving the foam wrapping efficiency of the plate heat exchanger.

[0008] Optionally, the cutting assembly includes a cutting plate and several cutting blades. The cutting plate is fixed on the work frame. The top wall of the cutting plate is provided with several horizontal grooves and several vertical grooves. The horizontal grooves are arranged along the length direction of the work frame, and the vertical grooves are arranged along the width direction of the work frame. The horizontal grooves and vertical grooves are arranged intersectingly. Several of the horizontal grooves and vertical grooves are arranged in a matrix. The cutting blades are inserted into the horizontal grooves and vertical grooves. The cutting blades are connected to the cutting plate through a push cylinder. The push cylinder is used to drive the cutting blades to extend out of the cutting plate.

[0009] By adopting the above technical solution, when it is necessary to cut foam of a specific shape, it is only necessary to control the push cylinders in the horizontal and vertical grooves corresponding to the edge of the shape to drive the cutting blades at the corresponding positions to rise, so that the rising cutting blades surround and form the desired cutting shape. When the foam moves over the cutting plate, the cutting blades rise and abut against the foam to cut it. When it is necessary to cut foam of other shapes, it is only necessary to adjust the rising combination of the cutting blades in other positions, without the need to replace the entire set of blades. This achieves rapid switching and cutting of foam of different shapes and improves the equipment's adaptability to plate heat exchangers of different specifications.

[0010] Optionally, a pressure plate is connected to the work frame via a lifting cylinder. The pressure plate is located directly above the cutting plate. The lifting cylinder is used to drive the pressure plate to move up and down, and the pressure plate is used to press the foam onto the cutting plate.

[0011] By adopting the above technical solution, when the foam moves to the cutting plate, the lifting cylinder drives the pressure plate to move down until the pressure plate presses against the foam, making the foam press firmly against the cutting plate. When the cutting blade rises, the pressure plate provides support, preventing the cutting blade from pushing the foam up when it moves upward, ensuring that the cutting blade can pierce the foam, thus improving cutting quality and cutting accuracy.

[0012] Optionally, the work frame is connected to two limiting plates via an adjusting rod. The two limiting plates are arranged opposite each other in the width direction of the work frame and are slidably connected to the work frame. The adjusting rod is arranged along the width direction of the work frame and is rotatably connected to the work frame. The two ends of the adjusting rod are provided with threaded structures with opposite directions of rotation. The two limiting plates are respectively sleeved on the two ends of the adjusting rod and are threadedly connected to the adjusting rod. When the adjusting rod rotates, it is used to drive the two limiting plates closer to or further apart from each other.

[0013] By adopting the above technical solution, when the operator rotates the adjusting rod, the two limiting plates move closer or further apart due to the opposite rotation of the threads at both ends of the adjusting rod. This adapts to foams of different widths, guides and limits the conveying path of the foam, prevents the foam from shifting during the conveying process, and ensures accurate cutting position.

[0014] Optionally, the cutting plate is provided with a mounting plate, and the cutting plate is provided with a moving cylinder. The output end of the moving cylinder is connected to the mounting plate and is used to drive the mounting plate to move up and down. The push cylinder is located on the mounting plate.

[0015] By adopting the above technical solution, when multiple foams of the same shape need to be cut, the corresponding cutting blade is selected and raised using a push-push cylinder, allowing the foam to move to the cutting blade for cutting. After cutting, the moving cylinder is activated to drive the mounting plate downwards, so that all cutting blades are submerged in the corresponding horizontal and vertical grooves. The surface of the cutting plate is smooth, facilitating the transport of subsequent uncut areas of long strips of foam to the cutting plate and avoiding scratches on the moving foam. When the complete uncut foam reaches the cutting plate, the moving cylinder is activated to drive the mounting plate upwards, and the previously raised cutting blades protrude directly from the cutting plate, eliminating the need to reselect the push-push cylinder and improving the efficiency of continuously cutting multiple foams of the same specification.

[0016] Optionally, the mounting plate is provided with a rotating assembly, the output end of the push cylinder is connected to a mounting block, the mounting block is slidably connected to the mounting plate, the cutting blade is rotatably connected to the mounting block, and the rotating assembly is connected to the cutting blade to drive the cutting blade to rotate.

[0017] By adopting the above technical solution, when the cutting blade comes into contact with the foam, the rotating component drives the cutting blade to rotate. The rotating cutting blade can cut the foam more smoothly during the cutting process, reducing cutting resistance, improving cutting quality, and ensuring that the foam is completely cut through.

[0018] Optionally, the rotating assembly includes a conveyor belt, a rotating rack, a rotating gear, and a transmission belt. The conveyor belt is rotatably connected to the mounting plate. The rotating rack is disposed on the inner wall of the conveyor belt. The transmission belt is disposed on the mounting block. The driving pulley of the transmission belt is coaxially fixed with the rotating gear. The driven pulley of the transmission belt is coaxially fixed with the cutting blade. The rotating gear is located inside the conveyor belt and meshes with the rotating rack on one side of the conveyor belt. The transverse or longitudinal grooves on the same straight line correspond to one conveyor belt.

[0019] By adopting the above technical solution, in the initial state, the rotating gear meshes with the rotating rack on the inner bottom wall of the conveyor belt. When the cutting blade needs to move upward, the push cylinder drives the mounting block upward, causing the rotating gear to move in the conveyor belt until the rotating gear meshes with the rotating rack on the inner top wall of the conveyor belt. The rotating gears connected to the cutting blades on the same straight line are located in the same conveyor belt. When driving the conveyor belt to rotate, the cutting blades on the same straight line can rotate simultaneously, so that the cutting blades forming the edge of the shape are uniformly driven to rotate and cut by the same conveyor belt, simplifying the drive structure and ensuring the synchronous rotation of the cutting blades in the same direction.

[0020] Optionally, two sprockets are rotatably connected to the side wall of the pressure plate. A chain is fitted on the sprocket and is arranged along the length of the work frame. The chain meshes with the sprockets, and the sprockets rotate to drive the chain to move. A pressure roller is connected to the chain via a connecting rod. The pressure roller is arranged along the width of the work frame, and the end of the pressure roller is rotatably connected to the connecting rod. The pressure roller can abut against the foam.

[0021] By adopting the above technical solution, when the pressure plate moves to a position close to the foam, the sprocket rotates, driving the chain to move. The connecting rod drives the pressure roller to move from the side of the pressure plate to below it and abut against the foam. The pressure roller moves along the chain, sliding along the surface of the foam in the length direction of the work frame. The pressure roller rotates synchronously, flattening the foam and pressing it against the cutting plate, allowing the foam to be cut flat and improving the accuracy of the cutting dimensions.

[0022] Optionally, the end of the pressure plate is connected to a pre-pressure rod via a fixing rod. The pre-pressure rod is vertically arranged and passes through the fixing rod. The bottom end of the pre-pressure rod can abut against the foam. A spring is sleeved on the pre-pressure rod, and the spring is used to drive the bottom end of the pre-pressure rod to move downward.

[0023] By adopting the above technical solution, when the pressure plate moves down to make the distance between the pressure plate and the foam reach the condition that the pressure roller can move, the bottom end of the pre-pressure rod first abuts against the foam, and the elastic force of the spring realizes the pre-tightening of the foam on both sides of the pressure plate, ensuring that the foam is immediately compressed and not easy to rebound when the pressure roller flattens the foam. Then the pressure plate moves down to make solid pressing, ensuring the stability of the flattening process.

[0024] Optionally, the pressure plate has a cavity, and a bottom plate at the bottom of the pressure plate blocks the bottom opening of the pressure plate. The bottom plate is slidably connected to the pressure plate, and a movable rack is fixed on the bottom plate. A movable gear is rotatably connected to the inner wall of the cavity, and the movable gear meshes with the movable rack. A suction cup is connected to the inner top wall of the cavity through a connecting cylinder, and the suction cup can adsorb foam.

[0025] By adopting the above technical solution, after the foam is cut, the rotating gear drives the rotating rack to move the base plate, exposing the suction cup. The connecting cylinder then moves the suction cup downwards to pick up the cut foam pieces. Simultaneously, the take-up roller rewinds the waste material, achieving simultaneous cutting and waste recycling, thus improving work efficiency.

[0026] In summary, this application includes at least one of the following beneficial effects: 1. Through the coordinated operation of the discharge roller, cutting assembly, buffer station and wrapping station, the entire process of foam feeding, cutting and wrapping is automated, which effectively improves the foam wrapping efficiency of plate heat exchangers. 2. The matrix-arranged cutting blades, combined with the selective drive of the push cylinder, allow for the cutting of foam of different shapes and sizes simply by switching the combination of rising cutting blades, without the need to replace the entire set of blades, thus improving the equipment's versatility and switching efficiency.

[0029] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0030] This application discloses an automatic strip-cutting and wrapping device. (Refer to...) Figure 1 and Figure 2The automatic strip cutting and wrapping equipment includes a working frame 1, a discharge roller 11, and a take-up roller 12. The discharge roller 11 and take-up roller 12 are respectively located at both ends of the working frame 1 along its length. The discharge roller 11 is used to release the rolled foam, and the take-up roller 12 is used to roll up the cut waste material. A cutting assembly 2 is provided on the working frame 1, and a buffer station and a wrapping station are located on the side of the working frame 1. The buffer station is used to collect the cut piece foam for temporary storage, and the wrapping station is equipped with a robotic arm (not shown in the figure) for picking up the foam from the buffer station and attaching it to the surface of the plate heat exchanger.

[0031] Reference Figure 2 and Figure 3 The cutting assembly 2 includes a cutting plate 21 and several cutting blades 22. The cutting plate 21 is fixed on the work frame 1, and several horizontal grooves 211 and several vertical grooves 212 are formed on the top wall of the cutting plate 21. The horizontal grooves 211 are arranged along the length direction of the work frame 1, and the vertical grooves 212 are arranged along the width direction of the work frame 1. The horizontal grooves 211 and the vertical grooves 212 are arranged in a matrix.

[0032] Reference Figure 4 and Figure 5 Each horizontal groove 211 and vertical groove 212 is equipped with a cutting blade 22. The cutting blade 22 is connected to the cutting plate 21 via a push cylinder 24. The push cylinder 24 is used to drive the cutting blade 22 to extend out of the top wall of the cutting plate 21.

[0033] Reference Figure 2 and Figure 6 During cutting, the push cylinders 24 in the horizontal grooves 211 and vertical grooves 212 corresponding to the edge of the shape to be cut are activated, driving the cutting blades 22 at the corresponding positions to rise. The rising cutting blades 22 surround and form the desired cutting shape. When the foam moves over the cutting plate 21, the surrounding cutting blades 22 cut the foam. When different shapes need to be cut, it is only necessary to switch and activate the push cylinders 24 at different positions to raise the corresponding cutting blades 22, without having to replace the entire set of blades.

[0034] Reference Figure 2 and Figure 7 The work frame 1 is also connected to a pressure plate 3 via a lifting cylinder 31, with the pressure plate 3 located directly above the cutting plate 21. The lifting cylinder 31 is fixed to the work frame 1, and its output end is connected to the pressure plate 3 to drive the pressure plate 3 to move up and down. During cutting, the lifting cylinder 31 drives the pressure plate 3 to move down, pressing the foam onto the cutting plate 21, and provides support when the cutting blade 22 rises, preventing the foam from arching.

[0035] Reference Figure 3 and Figure 4The cutting plate 21 has an internal mounting plate 25, and a moving cylinder 26 is located at the bottom of the cutting plate 21. The output end of the moving cylinder 26 is connected to the mounting plate 25 to drive the mounting plate 25 to move up and down. The push cylinder 24 is fixed on the mounting plate 25. When continuously cutting foam of the same specification, after the cutting is completed, the moving cylinder 26 drives the mounting plate 25 to move down, so that all the cutting blades 22 are submerged in the horizontal groove 211 and the vertical groove 212. The surface of the cutting plate 21 has no protrusions, which makes it easy for the uncut foam area to continue to move into place. After the new foam is in place, the moving cylinder 26 drives the mounting plate 25 to move up, and the selected cutting blade 22 protrudes out of the cutting plate 21 again to cut, without the need to reselect the push cylinder 24.

[0036] Reference Figure 5 and Figure 6 A rotating assembly 4 is provided on the mounting plate 25. The output end of the push cylinder 24 is connected to a mounting block 23, which is slidably connected to the mounting plate 25. The cutting blade 22 is rotatably connected to the mounting block 23. The rotating assembly 4 includes a conveyor belt 41, a rotating rack 42, a rotating gear 43, and a drive belt 44. The conveyor belt 41 is rotatably connected to the mounting plate 25, and the rotating rack 42 is located on the upper and lower sides of the inner wall of the conveyor belt 41. The drive belt 44 is located on the mounting block 23, and its driving pulley is coaxially fixed with the rotating gear 43, while its driven pulley is coaxially fixed with the cutting blade 22. The rotating gear 43 is located inside the conveyor belt 41 and meshes with the rotating rack 42 on one side of the conveyor belt 41. The cutting blades 22 corresponding to the transverse grooves 211 or longitudinal grooves 212 on the same straight line share one conveyor belt 41.

[0037] Initially, the rotating gear 43 meshes with the rotating rack 42 on the inner bottom wall of the conveyor belt 41. When the push cylinder 24 drives the mounting block 23 upward, the rotating gear 43 moves upward in the conveyor belt 41 until it meshes with the rotating rack 42 on the inner top wall of the conveyor belt 41. When the conveyor belt 41 rotates, it drives the rotating gear 43 on the same straight line to rotate synchronously, which is transmitted to the cutting blade 22 through the transmission belt 44, causing the cutting blade 22 to rotate during cutting.

[0038] Reference Figure 2 and Figure 7 Two sprockets 5 are rotatably connected to the side wall of the pressure plate 3, and the two sprockets 5 are spaced apart along the length of the work frame 1. Chains 51 are fitted onto the two sprockets 5, and the chains 51 are also spaced along the length of the work frame 1 and mesh with the sprockets 5. The sprockets 5 are driven to rotate by a motor, which in turn moves the chains 51. Pressure rollers 53 are connected to the chains 51 via connecting rods 52. The pressure rollers 53 are arranged along the width of the work frame 1, and their ends are rotatably connected to the connecting rods 52.

[0039] After the pressure plate 3 moves down close to the foam, the sprocket 5 rotates, driving the chain 51 to move. The connecting rod 52 drives the pressure roller 53 to move from the side of the pressure plate 3 to below the pressure plate 3 and to abut against the foam. During the movement, the pressure roller 53 rolls along the surface of the foam, flattening the foam and pressing it against the cutting plate 21.

[0040] Reference Figure 2 and Figure 7 The two ends of the pressure plate 3 along its length are connected to pre-compression rods 61 via fixing rods 6. The pre-compression rods 61 are vertically positioned and pass through the fixing rods 6, with their bottom ends abutting against the foam. A spring 62 is fitted onto the pre-compression rod 61, with one end abutting against the fixing rod 6 and the other end abutting against the top end of the pre-compression rod 61, used to drive the bottom end of the pre-compression rod 61 downwards. During the downward movement of the pressure plate 3, the pre-compression rods 61 contact the foam before the pressure plate 3, pre-compressing the foam.

[0041] Reference Figure 2 and Figure 7 The pressure plate 3 has a cavity 32 inside, and the bottom opening of the pressure plate 3 is sealed by a base plate 33. The base plate 33 is slidably connected to the pressure plate 3, and a movable rack 34 is fixed on the base plate 33. A movable gear 35 is rotatably connected to the inner wall of the cavity 32, and the movable gear 35 meshes with the movable rack 34. A suction cup 37 is connected to the inner top wall of the cavity 32 through a connecting cylinder 36, and the suction cup 37 is used to adsorb foam.

[0042] After cutting, the moving gear 35 rotates to drive the moving rack 34 to move, causing the base plate 33 to slide so that the bottom opening of the pressure plate 3 is exposed. The connecting cylinder 36 drives the suction cup 37 to move down and pick up the cut foam block. Then the connecting cylinder 36 retracts to lift the foam block, completing the pickup.

[0043] Reference Figure 1 and Figure 2 The work frame 1 is also equipped with two limiting plates 71, which are arranged opposite to each other in the width direction of the work frame 1 and are slidably connected to the work frame 1. An adjusting rod 7 is rotatably connected to the work frame 1, which is arranged along the width direction of the work frame 1. The two ends of the adjusting rod 7 are provided with threaded structures with opposite directions of rotation. The two limiting plates 71 are respectively sleeved on the two ends of the adjusting rod 7 and threadedly connected to the adjusting rod 7. When the adjusting rod 7 is rotated, the two limiting plates 71 move closer or further apart to accommodate foam of different widths.

[0044] The implementation principle of an automatic strip-cutting and covering device according to an embodiment of this application is as follows: The discharge roller 11 releases foam, which is conveyed along its length on the work frame 1. Two limiting plates 71 limit and guide the foam. When the foam reaches the cutting plate 21, the lifting cylinder 31 drives the pressure plate 3 to move downwards. The pre-pressure rod 61 first contacts the foam for pre-pressure, then the pressure roller 53 moves to flatten the foam, and the pressure plate 3 presses the foam onto the cutting plate 21. According to the required cutting shape, the push cylinders 24 in the corresponding transverse grooves 211 and longitudinal grooves 212 drive the cutting blade 22 to rise, forming the cutting shape. The moving cylinder 26 drives the mounting plate 25 to move upwards, causing the cutting blade 22 to protrude from the cutting plate 21. The cutting blade 22 rotates under the drive of the rotating component 4 to cut the foam. After cutting, the suction cup 37 picks up the cut foam blocks and transfers them to the buffer station. Waste material is wound up by the receiving roller 12. The robotic arm at the wrapping station picks up the foam from the buffer station, tears off the film, and sticks it to the surface of the plate heat exchanger to complete the wrapping. Throughout the process, when it is necessary to change the cutting shape, only the starting combination of the push cylinder 24 needs to be changed, without changing the cutting tools.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
