Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a spring grinding machine for small springs. Background Technology

[0002] Spring grinding machines are specialized equipment used to grind the two ends of springs. They use a high-speed rotating grinding wheel to grind the spring ends to make them flat, vertical, and meet the required precision. They are characterized by high automation and high grinding accuracy. They are key post-processing equipment in spring manufacturing. Small springs are small in size and have a precise structure. The flatness of the two ends of the springs directly affects the assembly accuracy and performance. Therefore, they are closely related to spring grinding machines.

[0003] A search revealed a Chinese announcement number (CN205630239U) disclosing a spring grinding machine, comprising a material tray, a transmission rod, and a push rod. The material tray includes a base and gears, with the gears detachably connected to the base. One end of the push rod is equipped with a movable tube. This invention allows for simple operation to achieve the extension and retraction of the push rod and the replacement of the gears, without the need to completely disassemble the material tray, thus saving manpower and resources, reducing worker operating time, and improving work efficiency.

[0004] The patent description mentioned above states that "when the diameter of the spring to be ground by the spring grinding machine changes, the moving tube is rotated, and the moving tube sleeved on the push rod moves along the thread to the appropriate position." After the filter plate is clogged, it takes a lot of time to replace or clean it. Small spring grinding machines are mostly single-machine or small-batch production models, which will directly slow down the delivery schedule, especially during periods of high order volume. In response to the above problems, a spring grinding machine for small springs is proposed. Utility Model Content

[0005] This utility model proposes a spring grinding machine for small springs, which aims to improve the problem that some existing spring grinding machines for small springs are difficult to disassemble and assemble in water storage tanks.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A spring grinding machine for small springs includes a mounting frame, a workbench fixedly connected to the top of the mounting frame, a water tank fixedly connected to the bottom outer end of the workbench, a disassembly and assembly mechanism slidably connected to the bottom left outer end of the water tank, a pump body fixedly connected to the outside of the water tank, a delivery pipe fixedly connected to the output end of the pump body, and an anti-backflow mechanism fixedly connected to the outside of the delivery pipe. The disassembly and assembly mechanism includes a sliding lever, which is slidably connected to the inside of the water storage tank. A cavity is provided on the left side of the outside of the water storage tank. A limit plate is slidably connected inside the cavity. A reset spring is sleeved on the outside of the sliding lever. A connecting component is fixedly connected to the bottom of the sliding lever.

[0007] The above solution allows for a reasonable structural design of the grinding spring machine. The disassembly and assembly mechanism slides within the water storage tank cavity via a sliding lever. Combined with a limiting plate and a return spring, it facilitates the easy disassembly and assembly of the water storage tank components. The operation is labor-saving and the machine is securely fixed, making internal cleaning and maintenance convenient. The anti-backflow mechanism ensures unidirectional water flow. The water storage tank, pump body, and delivery pipe work together to cool the grinding wheel, thus improving the overall ease of use and safety of the equipment.

[0008] As a further description of the above technical solution: The connecting assembly includes a second pull plate, which is externally fixedly connected to the bottom of the sliding lever, and a handle is fixedly connected to the bottom of the second pull plate.

[0009] With the above solution: In the connecting assembly, pull plate two is fixed to the bottom end of the sliding lever, and the handle is fixed to the bottom of pull plate two. Pulling the handle allows the sliding lever to slide directly within the water tank cavity via pull plate two, easily controlling the engagement or disengagement of the sliding lever with the component. Operation is more convenient and labor-saving, eliminating the need for direct contact with the sliding lever, improving the ease of use of the disassembly and assembly mechanism, and facilitating the quick disassembly, assembly, and maintenance of related components of the water tank.

[0010] As a further description of the above technical solution: The anti-backflow mechanism includes a mounting housing, a cross-shaped placement plate is fixedly connected to the top of the inner part of the mounting housing, a connecting housing is fixedly connected to the bottom of the cross-shaped placement plate, a sliding rod is slidably connected to the bottom of the outer part of the connecting housing, a mounting spring is sleeved on the outside of the sliding rod, and a sealing component is fixedly connected to the bottom of the outer part of the sliding rod.

[0011] The above solution involves an anti-backflow mechanism in which a cross-shaped plate is fixedly connected to the housing, a sliding rod is fitted with a spring and slidably connected to the bottom of the housing, and also connected to a sealing assembly. Water flow pushes the sealing assembly to compress the spring of the sliding rod, ensuring smooth water flow to the grinding wheel for cooling. When the water flow stops, the spring rebounds, causing the sliding rod to reset and seal with the sealing assembly, effectively preventing backflow, ensuring water circuit cleanliness, and improving the stability of the water circuit and the reliability of grinding wheel cooling in the grinding spring machine.

[0012] As a further description of the above technical solution: The sealing assembly includes a sealing plate, the outer side of which is fixedly connected to the outside of the sliding rod, and a sealing ring is fixedly connected to the bottom of the inner side of the mounting housing, with the outer side of the sealing plate fitting against the outer side of the sealing ring.

[0013] The above solution involves a sealing plate fixed to a sliding rod and a sealing ring fixed to the bottom of the housing. The two fit tightly together. When water flows, the sealing plate moves with the sliding rod to open the passage. When the flow stops, a spring returns, causing the sealing plate and sealing ring to re-fit. This ensures a tight and reliable seal, effectively preventing water backflow, ensuring clean unidirectional water flow, enhancing the sealing performance of the anti-backflow mechanism, and improving the operational stability of the grinding spring machine's water circuit.

[0014] As a further description of the above technical solution: The water storage tank is internally connected to a filter plate, and a pull plate is fixedly connected to the outer right side of the filter plate. The outer side of the sliding rod is locked to the outer bottom of the pull plate.

[0015] The above solution allows for the sliding filter plate inside the water tank to filter impurities in the water, ensuring a clean water path. The pull plate facilitates the removal and removal of the filter plate, and the sliding lever is locked to the bottom of the pull plate to securely fix the filter plate. When the filter plate needs to be replaced, simply operate the sliding lever to unlock it, making disassembly and assembly convenient. This ensures both the filtration effect and ease of maintenance, improving the water quality assurance capability and ease of use of the water tank.

[0016] As a further description of the above technical solution: A protective shell is fixedly connected to the top of the workbench. A motor is fixedly connected to the outer left side of the protective shell. A drive bevel gear is fixedly connected to the drive end of the motor. A housing is fixedly connected to the outer side of the drive bevel gear. A driven bevel gear is rotatably connected to the outer top of the housing. Grinding wheels are fixedly connected to both the upper and lower ends of the housing.

[0017] The above solution provides the following: the protective shell on the top of the workbench can shield the machining debris and ensure operational safety; the motor drives the active bevel gear, which in turn drives the housing to rotate, so that the grinding wheels at the upper and lower ends of the housing work synchronously. The double grinding wheel design improves the grinding efficiency, and the stable bevel gear transmission ensures that the grinding wheel speed is uniform. It combines protection and high efficiency, enhancing the stability, safety and work efficiency of the spring grinding machine.

[0018] As a further description of the above technical solution: A second motor is fixedly connected to the front top of the workbench, and a rotating placement disk is fixedly connected to the drive end of the second motor. Multiple placement tubes are fixedly connected to the outside of the rotating placement disk.

[0019] The above solution involves a second motor at the top of the workbench driving a rotating placement tray. Multiple placement tubes on the tray can simultaneously hold multiple small springs. The second motor provides stable power, causing the placement tray to rotate at a uniform speed, which in turn drives the springs to be transported to the processing position in an orderly manner. This eliminates the need for frequent manual feeding. The multi-placement tube design increases the processing capacity per batch, and automated conveying reduces manual intervention, thereby improving spring grinding efficiency and ensuring feeding accuracy.

[0020] As a further description of the above technical solution: A receiving box is fixedly connected to the bottom front side of the workbench. A drawer is slidably connected to the bottom front side of the receiving box. Multiple fixed housings are fixedly connected to the bottom inside the drawer. Limiting blocks are slidably connected inside the fixed housings. A sliding rod is fixedly connected to the top of the limiting block. A tension spring is sleeved on the outside of the limiting block. A rubber plate is fixedly connected to the top of the limiting block.

[0021] The above solution involves a drawer in the front receiving box of the workbench to collect the processed springs. Inside the drawer, a fixed housing contains a limiting block connected to a sliding rod and a rubber plate. A tension spring is installed to cushion the springs. When the springs fall in, they squeeze the rubber plate, causing the limiting block to compress the springs and reduce shock, thus preventing collision damage. Multiple fixed housings allow for categorized storage, and the drawer facilitates easy access. The shock-absorbing design protects the springs, improving the safety of material collection and the convenience of organization.

[0022] This utility model has the following beneficial effects: 1. In this utility model, pulling the handle causes the second pull plate to drive the sliding clamp and the limiting plate to squeeze the reset spring. After separating the first pull plate, the filter plate can be taken out. During installation, the filter plate is inserted, and the handle is released to allow the spring to rebound and clamp the first pull plate. The disassembly and assembly steps are simple. The spring provides a stable clamping force, which facilitates quick replacement of the filter plate, improves maintenance efficiency, and enhances the convenience and reliability of the device.

[0023] 2. In this utility model, starting the pump allows water from the storage tank to flow through the delivery pipe into the mounting housing. This squeezes the sealing plate, causing the sliding rod to compress the mounting spring. The water flows through the cross-shaped placement plate to the grinding wheel for cooling. When the water flow stops, the spring rebounds, causing the sealing plate to adhere to the sealing ring to prevent backflow. This provides stable and precise water supply and cooling, while preventing backflow ensures a clean water path, improving the safety and lifespan of the grinding wheel. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 1 to 3This utility model provides an embodiment of a spring grinding machine for small springs, including a mounting frame 1. The mounting frame 1 serves as the load-bearing foundation of the equipment, providing a stable mounting platform for components such as the worktable 2 and water tank 3, evenly distributing the weight of each part of the equipment to the ground. The worktable 2 is fixedly connected to the top of the mounting frame 1. The worktable 2 is the operating platform for spring grinding and is used to install the grinding mechanism. Its flat surface and high strength characteristics ensure accurate workpiece positioning during grinding, while also withstanding the impact and heat generated during grinding. The water tank 3 is fixedly connected to the outer bottom of the worktable 2, providing continuous water for the grinding process. The coolant supply system collects and temporarily stores used coolant to achieve coolant recycling, which saves resources and keeps the working environment clean. The bottom left side of the water tank 3 is slidably connected to the disassembly mechanism 6, and the water tank 3 is fixedly connected to the outside of the pump body. The pump body serves as the power source for coolant circulation, pressurizing the coolant in the water tank 3 and delivering it to the delivery pipe 7 to provide continuous cooling and lubrication to the grinding area. The output end of the pump body is fixedly connected to the delivery pipe 7, which provides a delivery channel for coolant and accurately guides the pressurized coolant to the grinding point. Its flexible characteristics can adapt to the movement of the grinding mechanism and avoid pipe damage caused by rigid connection. Specifically, the mounting frame 1 stably supports the equipment components and evenly distributes the weight; the worktable 2 ensures accurate workpiece positioning and withstands impact and heat during grinding; the water tank 3 supplies coolant and recycles it, saving resources; the pump pressurizes and delivers coolant, and the delivery pipe 7 gently guides the coolant to the grinding point to avoid damage, thus improving the overall stability, grinding accuracy, and resource utilization of the grinding spring machine.

[0028] An anti-backflow mechanism 8 is fixedly connected to the outside of the delivery pipe 7. The anti-backflow mechanism 8 includes a mounting housing 81, which provides installation space for the anti-backflow component and also participates in coolant delivery as part of the delivery pipe 7. Its pressure-resistant structure can withstand the liquid pressure inside the pipe. A cross-shaped placement plate 82 is fixedly connected to the top of the inner part of the mounting housing 81. The cross-shaped placement plate 82 provides stable support for the connecting housing 83 and distributes the weight of the connecting housing 83 to the inner wall of the mounting housing 81. At the same time, the cross-shaped structure minimizes the obstruction to coolant flow while ensuring support strength. A connecting housing 83 is fixedly connected to the bottom of the cross-shaped placement plate 82. The connecting housing 83 is a sliding rod 8. 4. The mounting spring 85 provides guidance and installation space, restricts the radial movement of the sliding rod 84, and ensures that it can only slide up and down axially. The sliding rod 84 is slidably connected to the outer bottom end of the connecting housing 83. Under the action of coolant pressure and mounting spring 85, the sliding rod 84 drives the sealing assembly 86 to move up and down. The mounting spring 85 is sleeved on the outside of the sliding rod 84. The mounting spring 85 pushes the sealing assembly 86 downward by its elastic force, so that the sealing assembly 86 maintains a sealed state when there is no liquid pressure. When the pump body is working and the coolant pressure is greater than the spring force, the spring is compressed. The sealing assembly 86 is fixedly connected to the outer bottom end of the sliding rod 84. The sealing assembly 86 includes a sealing plate 861. Specifically, in the anti-backflow mechanism 8, the housing 81 is hydraulically supported and provides a mounting base for components; the cross-shaped plate 82 stably supports the connecting housing 83 and minimizes resistance to fluid flow; the sliding rod 84 of the connecting housing 83 slides axially; the installed spring 85 pushes the sealing component 86 to seal when there is no pressure; when the coolant is pressurized, the spring compresses to allow the fluid to pass through, preventing coolant backflow, ensuring stable cooling supply, and improving the reliability of the grinding spring machine.

[0029] The sealing plate 861 is tightly fitted with the sealing ring 862 under the push of the mounting spring 85 to form a sealing surface. When the coolant flows in the forward direction, the liquid pressure pushes the sealing plate 861 to move upward against the spring force and open the channel. When the liquid flows in the reverse direction or the pressure disappears, it resets under the action of the spring force and re-forms a seal to prevent backflow. The outer side of the sealing plate 861 is fixedly connected to the outside of the sliding rod 84. The inner bottom of the mounting housing 81 is fixedly connected to the sealing ring 862. The sealing ring 862 and the sealing ring of the sealing plate 861 form a double sealing structure to enhance the sealing effect. Even under low pressure, it can effectively prevent coolant backflow. The outer side of the sealing plate 861 is in contact with the outer side of the sealing ring 862. Specifically, the sealing plate 861 is tightly fitted with the sealing ring 862 under the push of the installation spring 85 to form a seal. When the coolant flows in the forward direction, the push plate moves away to open the channel, and when it flows in the reverse direction or without pressure, the spring helps it to reset and seal. The double sealing structure enhances the effect and can effectively prevent backflow even under low pressure, ensuring stable unidirectional delivery of coolant and improving the reliability of the grinding spring machine cooling system.

[0030] Reference Figures 2 to 4 The disassembly and assembly mechanism 6 includes a sliding latch 61. The sliding latch 61 engages with the sealing cover groove of the water tank 3 through a wedge-shaped latch head to achieve quick locking or unlocking of the sealing cover. The sliding latch 61 is externally slidably connected to the inside of the water tank 3. A cavity 62 is provided on the left side of the outside of the water tank 3. The cavity 62 provides installation space for the limiting plate 63 and the return spring 64, while protecting the internal components from the corrosion of coolant and ensuring long-term stable operation of the mechanism in a humid environment. The limiting plate 63 is slidably connected inside the cavity 62. The limiting plate 63 slides synchronously with the sliding latch 61, which can limit the maximum stroke of the sliding latch 61 and evenly transmit the elastic force of the return spring 64 to the sliding latch 61, ensuring stable and reliable locking force. The return spring 64 is sleeved on the outside of the sliding latch 61. Specifically, in the disassembly and assembly mechanism 6, the sliding latch 61 cooperates with the wedge-shaped latch head and the sealing cover groove of the water tank 3 to achieve quick locking or unlocking; the cavity 62 protects the internal components from coolant corrosion and ensures stable operation in a humid environment; the limiting plate 63 limits the travel of the latch and evenly transmits the elastic force of the reset spring 64 to ensure stable locking force, improve the ease of disassembly and assembly of the sealing cover and the durability of the mechanism.

[0031] The return spring 64 pushes the limiting plate 63 and the sliding lever 61 downwards through its elastic force, keeping the wedge-shaped head of the sliding lever 61 in an extended state to ensure a tight engagement with the sealing cover groove. This prevents the water tank 3 from leaking due to vibration during operation. A connecting assembly 65 is fixedly connected to the bottom of the sliding lever 61. The connecting assembly 65 includes a pull plate 651, which increases the force-bearing area at the bottom of the sliding lever 61, allowing the operator to pull the sliding lever 61 with less effort. Simultaneously, its planar structure stably connects to the handle 652, ensuring... The force is evenly transmitted. The pull plate 651 is externally fixedly connected to the bottom of the sliding lever 61. The bottom of the pull plate 651 is fixedly connected to the handle 652, which provides a convenient grip point for the operator. By pulling the handle 652 upward, the pull plate 651 and the sliding lever 61 can be driven to rise synchronously, compressing the return spring 64 and causing the locking head to disengage from the sealing cover slot, thus unlocking the sealing cover. After releasing the handle 652, it automatically resets and locks under the action of the return spring 64. The operation is simple and effortless, and the anti-slip texture can prevent the hand from slipping, improving the safety of operation. Specifically, the reset spring 64 pushes the limit plate 63 and the sliding lever 61 downwards, allowing the retaining head to extend and tightly lock the sealing cover groove, preventing water tank 3 from vibrating and leaking; the pull plate 651 in the connecting component 65 increases the force-bearing area, and the handle 652 provides a gripping point. Pulling the handle 652 unlocks the device, and releasing it automatically resets and locks it, making operation effortless. The anti-slip texture ensures safety and improves the convenience and reliability of the sealing cover installation and removal.

[0032] Reference Figures 3 to 5A filter plate 4 is slidably connected inside the water tank 3. The filter plate 4 filters the coolant flowing back to the water tank 3, intercepting metal chips and impurities generated during grinding. This prevents impurities from entering the pump body and causing damage, or from re-entering the grinding area with the coolant and affecting machining accuracy. A pull plate 5 is fixedly connected to the outer right side of the filter plate 4. The pull plate 5 provides a force point for pulling out the filter plate 4, making it easy for operators to quickly remove the filter plate 4 from the water tank 3 for cleaning. The outer side of the sliding latch 61 is locked to the outer bottom of the pull plate 5. A protective shell 9 is fixedly connected to the top of the worktable 2. The protective shell 9 can block metal chips and coolant splashed during grinding, protecting operators from injury. Meanwhile, the transparent material facilitates observation of the processing. A motor 10 is fixedly connected to the outer left side of the protective housing 9. The motor 10 provides rotational power to the grinding wheel 14. By adjusting the speed, it can adapt to spring grinding with different materials and precision requirements. A drive bevel gear 11 is fixedly connected to the drive end of the motor 10. The drive bevel gear 11 transmits the horizontal rotational power of the motor 10 to the driven bevel gear 13, realizing the vertical conversion of the motion direction and providing a suitable rotation direction for the grinding wheel 14. A housing 12 is fixedly connected to the outside of the drive bevel gear 11. The housing 12 provides protection and lubrication space for the bevel gear transmission, preventing coolant and debris from entering the gear meshing area and affecting the transmission accuracy. Specifically, the filter plate 4 filters impurities in the coolant to prevent damage to the pump body and affect machining accuracy; the pull plate 5 allows for easy removal and cleaning; the protective shell 9 blocks debris and coolant, protecting personnel and facilitating observation; the motor 10 supplies power to the grinding wheel 14; the bevel gear changes the transmission direction; the housing 12 protects the gears from impurities, thus improving the overall safety, machining accuracy, and ease of maintenance of the grinding spring machine.

[0033] A driven bevel gear 13 is rotatably connected to the top of the outer side of the housing 12. The driven bevel gear 13 receives power from the driving bevel gear 11 and changes its rotation direction, driving the grinding wheel 14 to rotate at high speed. Grinding wheels 14 are fixedly connected to both the upper and lower ends of the outer side of the housing 12. When the grinding wheel 14 rotates at high speed, it grinds the spring through the abrasive layer. The design of the upper and lower double grinding wheels 14 can process both ends of the spring at the same time, improving processing efficiency. A second motor 15 is fixedly connected to the front of the top of the worktable 2. The second motor 15 provides intermittent rotational power to the rotating placement disk 16. By precisely controlling the rotation angle, the springs in the placement tube 17 are moved sequentially to the processing position of the grinding wheel 14. A rotating placement disk 16 is fixedly connected to the drive end. The rotating placement disk 16 serves as a bearing and conveying component for the spring. By rotating, it transfers the spring to be processed to the grinding station and simultaneously moves the processed spring to the material picking station. Its disc structure ensures stable and accurate feeding. Multiple placement tubes 17 are fixedly connected to the outside of the rotating placement disk 16. The placement tubes 17 are used to position and clamp the spring to be processed, preventing the spring from shifting or falling off during rotation and grinding. The guide chamfer facilitates the smooth placement of the spring into the tube. A receiving box 18 is fixedly connected to the bottom front side of the worktable 2. The receiving box 18 is used to collect the processed spring, preventing the spring from falling directly to the ground and causing damage or scattering. Specifically, the driven bevel gear 13 drives the double grinding wheel 14 to rotate at high speed, which can process both ends of the spring at the same time to improve efficiency; the motor 2 15 controls the rotation of the placement plate 16 to rotate intermittently and send the spring to the work station; the placement tube 17 positions the spring to prevent it from deviating, and the receiving box 18 collects the finished product to prevent it from being damaged and scattered, thus improving the overall processing efficiency, feeding accuracy and finished product protection effect of the spring grinding machine.

[0034] A drawer 20 is slidably connected to the front of the receiving box 18. Multiple fixed housings 21 are fixedly connected to the bottom of the drawer 20. The fixed housings 21 provide installation space for the limiting block 22 and the tension spring 23, and at the same time play a preliminary positioning role for the spring, preventing multiple springs from colliding and wearing each other inside the drawer 20. The limiting block 22 is slidably connected inside the fixed housing 21. The limiting block 22 moves upward under the action of the tension spring 23. The rubber plate 19 on the top applies elastic pressure to the spring, realizing the flexible fixation of the spring. A sliding rod 24 is fixedly connected to the top of the limiting block 22. The tension spring 23 is sleeved on the outside of the limiting block 22. The rubber plate 19 is fixedly connected to the top of the limiting block 22. The rubber plate 19 is in direct contact with the spring. Its softness can prevent the spring from being rigidly clamped and causing surface scratches. The anti-slip texture can increase the friction with the spring and improve the fixing effect. At the same time, the elasticity of the rubber can further absorb vibration. Specifically, inside the drawer 20 of the receiving box 18, the fixed shell 21 prevents the spring from colliding and wearing; the tension spring 23 pushes the limit block 22 upward, and the rubber plate 19 flexibly fixes the spring; the rubber plate 19 avoids scratches, increases friction and absorbs vibration, ensures the stability of finished product storage, protects the surface quality of the spring, and improves the protection effect of receiving materials.

[0035] Working principle: When disassembling and assembling the filter plate 4, by pulling the handle 652, the handle 652 drives the pull plate 651 to slide, which in turn drives the sliding rod 61 to slide inside the cavity 62. The sliding rod 61 then slides inside the cavity 62 through the limiting plate 63, which in turn compresses the return spring 64, causing the return spring 64 to deform. This causes the sliding rod 61 to separate from the pull plate 5, and by pulling the pull plate 5, the filter plate 4 can be removed from the water storage tank 3. When installing the filter plate 4, by inserting the filter plate 4, and then by releasing the handle 652, the return spring 64 outside the sliding rod 61 rebounds, which then locks the sliding rod 61 into the pull plate 5, thus enabling the installation of the filter plate 4. By activating the pump, water from the storage tank 3 flows through the delivery pipe 7 into the mounting housing 81. This water flow then compresses the sealing plate 861, causing the sealing plate 861 to compress the sliding rod 84. This compresses the mounting spring 85 outside the sliding rod 84, causing the mounting spring 85 to deform. This allows the water to flow through the cross-shaped placement plate 82 into the delivery pipe 7, and then flow towards the outside of the grinding wheel 14, thus cooling the grinding wheel 14. When the water flow stops, the mounting spring 85 rebounds, causing the sealing plate 861 to come into contact with the sealing ring 862, thereby preventing backflow of water. As the material falls from the workbench 2 into the receiving box 18, it enters the rubber plate 19, which in turn squeezes the sliding rod 24. This causes the sliding rod 24 to drive the limiting block 22 to squeeze the tension spring 23, thus preventing damage to the material during feeding.
