A temperature switch insulating paper feeding device

Abstract

This invention belongs to the field of material feeding technology and proposes a feeding device for temperature switch insulating paper. It includes a base, with a second support frame sleeved at the upper center of the base. Two first support frames are symmetrically installed on both sides of the second support frame. Each of the two first support frames is equipped with a vertically positioned steering shaft and a meshing feeding shaft. The upper and lower sides of the interior of the second support frame are connected to a first adjustment mechanism and a second adjustment mechanism for cyclic clamping and releasing. The first and second adjustment mechanisms pull the middle of the paper tape, accompanied by automatic telescopic movement, so that the paper tape is tensioned during conveying and automatically adapts to the tension of the paper tape. This prevents the insulating paper tape from becoming misaligned or deformed due to paper tape bending, facilitates paper tape feeding, and prevents the paper tape from being affected by the material roll during feeding, causing tearing and damage that affects quality.

Description

Technical Field

[0001] This invention relates to a temperature switch insulating paper feeding device, belonging to the field of production feeding technology. Background Technology

[0002] A temperature switch is a type of temperature switch that uses a bimetallic strip as the temperature sensing element. It is a low-cost bimetallic strip overheat-induced contact. The bottom surface of the rectangular housing of the temperature controller needs to be lined with insulating paper to ensure insulation between the housing and the stationary contact lead-out piece. Therefore, during the manufacturing process of the temperature switch, the insulating paper needs to be transported, processed, and assembled onto the temperature control switch.

[0003] Existing insulating paper feeding devices lack self-correction mechanisms in their insulating paper feeding processes. Inaccurate feeding or paper deformation can cause the cut insulating paper to fail to meet accuracy requirements. Current feedback mechanisms typically only correct problems after they occur, failing to achieve real-time self-adjustment. Furthermore, paper curvature is a major cause of paper misalignment or jamming, and it can also lead to tearing and cracking, affecting the quality of the insulating paper. Therefore, real-time and proper adjustment of paper curvature is necessary.

[0004] Therefore, we have made improvements to this by proposing a temperature switch insulating paper feeding device. Summary of the Invention

[0005] (I) The technical problem to be solved by the present invention is that the existing insulating paper feeding device does not have a self-correction function in the mechanism for conveying insulating paper. The curvature of the insulating paper is prone to paper deviation, paper jam and tearing, which affects the quality of the insulating paper. It is necessary to adjust the curvature in real time.

[0006] (II) Technical Solution

[0007] To achieve the above-mentioned objectives, this invention provides a temperature switch insulating paper feeding device, comprising a base, a second support frame sleeved at the upper center of the base, and two first support frames symmetrically mounted on both sides of the second support frame. Each of the two first support frames is equipped with a vertically positioned steering shaft and a meshing feeding shaft. The upper and lower sides of the interior of the second support frame are connected to a first adjustment mechanism and a second adjustment mechanism for cyclic clamping and releasing. Both the first and second adjustment mechanisms have an air blowing mechanism sleeved inside. The feeding shaft and steering shaft drive the paper tape for conveying and steering. The first and second adjustment mechanisms are installed in the middle of the paper tape to pull it. When clamped, the first and second adjustment mechanisms fix the paper tape to prevent it from retracting and falling off. During the releasing process, the first and second adjustment mechanisms pull the paper tape to adapt to the tension of the paper tape and prevent it from shifting or misaligning. When completely released, the first and second adjustment mechanisms work with the feeding shaft and the air blowing mechanism to correct and flatten the paper tape.

[0008] The base includes a tabletop, on both sides of which are symmetrically arranged sliding grooves, and a positioning hole is provided in the middle of the lower baffle of the sliding groove.

[0009] The first support frame includes a column, the bottom of which is connected to a slider. The slider is slidably installed inside a groove. An installation groove is provided inside the slider. A pneumatic pin is fixedly installed inside the installation groove. The bottom of the pneumatic pin is connected to a pin that is adapted to and engages with a positioning hole.

[0010] The second support frame includes a screw lifting frame, a screw connecting block that slides inside the screw lifting frame, a pin that is consistent with the pneumatic pin that is installed inside the screw connecting block, and the upper end of the screw connecting block is connected to the second adjustment mechanism.

[0011] The column is rotatably connected to a first cylinder at its center, and the other end of the first cylinder is rotatably sleeved on a screw connecting block.

[0012] The first adjustment mechanism is fixedly connected to the upper side of the second support frame, and the second adjustment mechanism is movably installed on the lower side of the second support frame. The second adjustment mechanism includes a traction shaft, and two connecting sleeves are symmetrically sleeved at both ends of the traction shaft. The two connecting sleeves are slidably installed inside the side column of the second support frame, and a second cylinder is connected to the bottom of the connecting sleeve. The second cylinder is fixedly connected to the top surface of the screw connecting block.

[0013] The traction shaft is a hollow cylinder in the middle, and circular holes are arranged in an array on the circumference of the traction shaft. An air blowing mechanism is sleeved inside the circular holes.

[0014] The blowing mechanism includes an exhaust pipe, an air inlet pipe connected to the end of the exhaust pipe, an air outlet protruding from the upper surface of the exhaust pipe, and a dome-shaped conical foam plug and a spring telescopic rod connected inside the air outlet. The plug is connected to the inner wall of the air inlet pipe through the spring telescopic rod and is fitted into the inside of the round hole through the air inlet pipe.

[0015] (III) Beneficial Effects

[0016] The temperature switch insulating paper feeding device provided by this invention has the following advantages:

[0017] 1. The first and second adjustment mechanisms pull the middle of the paper tape and automatically extend and retract it to tension the paper tape during the conveying process. This automatically adapts to the tension of the paper tape, preventing the insulating paper tape from deviating or deforming due to paper tape bending. This facilitates the feeding of the paper tape and prevents the paper tape from being affected by the material roll during the feeding process, which could cause bending changes, tearing, or damage that would affect the quality.

[0018] 2. By clamping and fixing the paper tape under the extrusion of the first and second adjustment mechanisms, it is convenient to fix the middle part of the paper tape during the cutting process at the end of the paper tape, so as to avoid the paper tape from springing back and falling off after being cut, and to facilitate the stable and continuous conveying and processing of the paper tape.

[0019] 3. Through the final retraction action of the first and second adjustment mechanisms, the surfaces of the first and second adjustment mechanisms are separated from the raw material surface. In conjunction with the air blowing mechanism, the paper tape is smoothed by blowing air onto the surfaces of the first and second adjustment mechanisms. At the same time, the retraction action of the first and second adjustment mechanisms corrects the misaligned paper tape, preventing wrinkles from forming during the conveying process. At this time, the raw material at the middle position of the first support frame at both ends is flattened and unfolded. During the flattening process, the paper tape is corrected by the conveying of the feeding shaft. Attached Figure Description

Detailed Implementation

[0027] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0028] like Figures 1-5 As shown, this embodiment proposes a temperature switch insulating paper feeding device, including a base 1. A second support frame 3 is sleeved and installed at the upper middle part of the base 1, and two first support frames 2 are symmetrically installed on both sides of the second support frame 3. Each of the two first support frames 2 is equipped with a vertically placed steering shaft 5 and a meshing feeding shaft 4. The feeding shaft 4 includes two transmission rollers with meshing end gears, and one of them is externally connected to a drive motor. During the meshing process of the feeding shaft 4, it drives the paper belt to drive. The upper and lower sides of the interior of the second support frame 3 are connected to a first adjustment mechanism 6 and a second adjustment mechanism 7 for cyclic clamping and releasing. The first adjusting mechanism 6 and the second adjusting mechanism 7 are both fitted with an air blowing mechanism 8. The feeding shaft 4 and the steering shaft 5 drive the paper belt to be conveyed and turned. The first adjusting mechanism 6 and the second adjusting mechanism 7 are installed in the middle of the paper belt to drive the paper belt to be pulled. When the first adjusting mechanism 6 and the second adjusting mechanism 7 clamp, they fix the paper belt to prevent the paper belt from shrinking and falling off. When the first adjusting mechanism 6 and the second adjusting mechanism 7 are relaxed, they pull the paper belt to adapt to the tension of the paper belt and prevent the paper belt from deviating or misaligning. When the first adjusting mechanism 6 and the second adjusting mechanism 7 are completely released, they work with the feeding shaft 4 and the air blowing mechanism 8 to correct and flatten the paper belt.

[0029] The base 1 includes a table 11, with symmetrical sliding grooves 12 on both sides of the table 11. A positioning hole 13 is provided in the middle of the baffle below the sliding groove 12. The positioning hole 13 and the sliding groove 12 are designed to facilitate connection with the first support frame 2, allowing for sliding adjustment of the position after the first support frame 2 is installed. The positioning hole 13 and the first support frame 2 are fixed by a pin, which facilitates the stable support of the first support frame 2 for the feeding shaft 4 and the steering shaft 5.

[0030] The first support frame 2 includes a column 21, with a slider 22 connected to the bottom of the column 21. The slider 22 is slidably installed inside the slide groove 12. An installation groove 24 is provided inside the slider 22, and a pneumatic pin 25 is fixedly installed inside the installation groove 24. The bottom of the pneumatic pin 25 is connected to a pin that is adapted to and engages with the positioning hole 13. The column 21 is used to install the feeding shaft 4 and the steering shaft 5, and slides and positions itself with the positioning hole 13 through the slider 22 and the pneumatic pin 25, thereby adjusting the position of the first support frame 2 so that the feeding shaft 4 and the steering shaft 5 on the first support frame 2 can better tension and convey the paper tape.

[0031] The second support frame 3 includes a screw lifting frame 31, inside which a screw connecting block 32 slides. Inside the screw connecting block 32, a pin identical to the pneumatic pin 25 is installed. The upper end of the screw connecting block 32 is connected to the second adjustment mechanism 7. The second support frame 3 includes a U-shaped frame, and the two side columns of the frame are equipped with symmetrical lead screws. The symmetrical lead screws are connected to the two ends of the screw connecting block 32 and drive the transmission. The bottom of the symmetrical lead screws is equipped with meshing double gears, and the double gears at the bottom of the two side columns of the frame are connected by a chain. The first cylinder 23 is controlled by the switch of the pin on the screw connecting block 32 or the switch of the pneumatic pin 25 to drive the screw connecting block 32 to adjust up and down on the second support frame 3 or to drive the first support frame 2 to slide on both sides of the second support frame 3. During the up and down movement of the screw connecting block 32 by the first cylinder 23, the screw connecting blocks 32 on both sides of the frame are synchronously linked by the lead screw, gears and chain.

[0032] The first cylinder 23 is rotatably connected to the middle of the column 21. The other end of the first cylinder 23 is rotatably sleeved on the screw connecting block 32. The connection of the first cylinder 23 drives the screw connecting block 32 to adjust up and down on the second support frame 3 or drives the first support frame 2 to slide on both sides of the second support frame 3. Adjusting the second adjustment mechanism 7 connected to the screw connecting block 32 and the feeding shaft 4 on the first support frame 2 adjusts the conveying tension of the paper tape, which facilitates the use of the device.

[0033] The first adjustment mechanism 6 is fixedly connected to the upper side of the second support frame 3, and the second adjustment mechanism 7 is movably installed on the lower side of the second support frame 3. The second adjustment mechanism 7 includes a traction shaft 71, and two connecting sleeves 72 are symmetrically sleeved at both ends of the traction shaft 71. The two connecting sleeves 72 are slidably installed inside the side column of the second support frame 3, and the bottom of the connecting sleeve 72 is connected to a second cylinder 73. The second cylinder 73 is fixedly connected to the top surface of the screw connecting block 32. The first adjustment mechanism 6 and the second adjustment mechanism 7 have the same structure and are symmetrically installed on the upper and lower sides of the second support frame 3 to perform tightening and loosening clamping actions. The bottom of the second adjustment mechanism 7 is connected to the screw connecting block 32 through the connecting sleeve 72 and the second cylinder 73. The height of the second adjustment mechanism 7 installed inside the second support frame 3 is adjusted by the screw connecting block 32, changing the distance between the first adjustment mechanism 6 and the second adjustment mechanism 7, so as to change the clamping effect between the first adjustment mechanism 6 and the second adjustment mechanism 7.

[0034] The traction shaft 71 is a hollow cylinder in the middle. Circular holes 74 are arrayed on the circumference of the traction shaft 71. An air blowing mechanism 8 is sleeved inside the circular holes 74. The opening of the circular holes 74 and the sleeve of the air blowing mechanism 8 allow the air blowing mechanism 8 to exhaust air evenly around the circumference of the second adjustment mechanism 7. The airflow smooths out the paper tape connected to the second adjustment mechanism 7 and prevents wrinkles from forming on the paper tape.

[0035] The air blowing mechanism 8 includes an exhaust pipe 81, with an air inlet pipe 82 connected to the end of the exhaust pipe 81. An air outlet 83 is protruding from the upper surface of the exhaust pipe 81. Inside the air outlet 83, there is a dome-shaped conical foam plug 84 and a spring telescopic rod 85. The plug 84 is connected to the inner wall of the air inlet pipe 82 through the spring telescopic rod 85 and fits into the inside of the round hole 74. The plug 84 is conical in shape and smaller than the inner diameter of the round hole 74. The dome of the plug 84 is pushed out of the round hole 74 by the spring telescopic rod 85, and the gas is discharged through the round hole 74 and the exhaust pipe 81. The gas blows and smooths the paper tape, preventing wrinkles from forming during the paper tape transmission process.

[0036] Specifically, in use, the insulation paper feeding device for this temperature switch works as follows: The upper end of the base 1 is supported by a second support frame 3, which houses the first adjustment mechanism 6 and the second adjustment mechanism 7. Symmetrical first support frames 2, feeding shafts 4, and steering shafts 5 are installed on both sides of the second support frame 3. The paper strip material is fed in from the middle of the feeding shaft 4 on the front side, pulled above the surface of the second adjustment mechanism 7, and then exited through the middle of the feeding shaft 4 on the rear side. Guided by the steering shaft 5 on the rear side, it winds around the lower part of the first adjustment mechanism 6, is pulled again below the surface of the first adjustment mechanism 6, and then passes through the middle of the feeding shaft 4 on the front side. The guide shaft 5 discharges the material, and during the traction process of the first adjusting mechanism 6 and the second adjusting mechanism 7, the first adjusting mechanism 6 and the second adjusting mechanism 7 perform cyclic extension and retraction springback actions. Initially, the first adjusting mechanism 6 and the second adjusting mechanism 7 are installed in the middle of the second supporting frame 3 at both ends of the first supporting frame 2 and are connected by compression. At this time, the feeding shaft 4 remains in a paused state during the intermittent process. The springback between the first adjusting mechanism 6 and the second adjusting mechanism 7 can squeeze and clamp the upper and lower layers of paper tape. The end of the paper tape is punched inside the paper cutter (not shown). At this time, the paper tape is fixed during the paper tape processing and cutting process to prevent it from overflowing. The paper tape retracts; subsequently, the first adjusting mechanism 6 and the second adjusting mechanism 7 retract inside the second support frame 3. The raw material, located in the middle of the device, is constantly bidirectionally pulled by the first adjusting mechanism 6 and the second adjusting mechanism 7, automatically adapting to the surface tension of the raw material and being squeezed and conveyed by the feeding shaft 4 and the steering shaft 5 on the first support frame 2, driving the paper tape to move. Finally, the first adjusting mechanism 6 and the second adjusting mechanism 7 move to both ends of the second support frame 3 as the tape retracts. After retraction, the first adjusting mechanism 6 and the second adjusting mechanism 7 separate from the surface of the raw material, flattening and unfolding the raw material at the middle position of the first support frame 2 at both ends. During the flattening process, the paper tape is corrected by the conveying of the feeding shaft 4. At the same time, the first adjusting mechanism 6 and the second adjusting mechanism 7 are equipped with an air blowing mechanism 8. The air blowing mechanism 8 is connected to an external air source (not shown) and then vents through the round hole 74 and the exhaust pipe 81. The air blows and smooths the paper tape to prevent wrinkles from forming during the paper tape conveying process. At this time, the raw material is fed to the designated position in a flat state. The first adjusting mechanism 6 and the second adjusting mechanism 7 quickly spring up and continue to clamp and fix the paper tape through the first adjusting mechanism 6 and the second adjusting mechanism 7 to process the paper tape. Then the above operation is repeated.

[0037] The above embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. Although the invention has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of the invention do not depart from the spirit and scope of the invention and should be covered within the scope of the claims of the invention.
