Description

Technical Field

[0001] The invention relates to the technical field of hand looms, in particular to a wide-width hand loom. Background Art

[0002] A wide hand loom is a traditional hand weaving tool used to weave wide fabrics. It is usually made of wood, metal and other materials and relies on manual operation to complete the weaving process. This type of loom is usually larger than a standard narrow loom and can weave wider fabrics. It is widely used in the production of large-scale fabric products such as bed sheets, curtains, and carpets.

[0003] The patent with patent announcement number CN210177051U relates to a hand loom that improves traditional weaving technology, including a frame, and vertical poles are symmetrically fixed to the top rear of the frame by bolts, and the top side of the vertical pole is fixed to the suspension rod by bolts, and the two inner sides of the front end of the suspension rod are fixed with suspension columns by bolts, and a circular ring is fixed to the bottom front side of the vertical pole. The bottom of the suspension column and the front side of the circular ring are hung with hook springs, and a weft guide plate is connected to the top front of the frame, and a pair of guide plate struts are hinged at the bottom of the weft guide plate. The patent uses the foot to pedal the guide plate struts to make the weft guide plate slide and press the line on the frame, so that the weft and warp are staggered and superimposed, and reset under the tension of the hook spring, so that both hands only need to thread the shuttle, and there is no need to bend the weft guide plate, which makes the arms relaxed and the shuttle threading faster.

[0004] In the above patent, the weft guide plate is slid and pressed on the frame by pedaling the guide plate support rod, so that the weft and warp are interlaced and superimposed, and reset under the tension of the hook spring, so that both hands only need to thread the shuttle, and there is no need to bend the weft guide plate, which makes the arms lighter and the shuttle threading faster. However, if the pedal shaft is not lubricated for a long time, it will cause increased pedal wear, frequent failures, and uneven operation, which will cause the staff to exert more force to operate the pedal, which not only increases labor intensity, but may also lead to inaccurate operation and reduce work efficiency. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention provides a wide-width hand loom, which solves the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A wide-width hand loom, comprising a loom body, a vertical rod fixedly mounted on the inner wall of the loom body, a weft pressing plate rotatably mounted on the inner wall of the loom body, a No. 1 L-shaped plate fixedly mounted on the inner wall of the loom body, and further comprising a lubricating device, a protective device, and a collecting device; The oil pump of described oil tank is connected with the oil pump of described oil tank cap, and the oil pump of described oil tank cap is connected with the oil pump of described oil tank cap.

The two pedals are symmetrically distributed around the center of the textile machine body, which facilitates the recovered oil to flow into the bottom of the oil tank and facilitates the extrusion rod to squeeze the guide plate.

[0008] According to the above technical solution, the protective device includes a connecting rope, a palm frame, a fixing plate, an elastic telescopic rod and a limit block, the palm frame is slidably mounted on the inner wall of the vertical rod, one end of the connecting rope is fixedly mounted on the top of the pedal, and the other end of the connecting rope is fixedly connected to the bottom of the palm frame, the fixing plate is fixedly mounted on the top of the palm frame, the elastic telescopic rod is fixedly mounted on the side of the fixing plate close to the vertical rod, the limit block is slidably mounted on the top of the palm frame, and the limit block is fixedly mounted on the telescopic end of the elastic telescopic rod. The connecting rope moves up and down, driving the palm frame to move up and down. At the same time, when the palm frame moves up and down, it drives the limit block to move up and down. When the limit block moves up and down a certain distance, it contacts the limit groove and under the action of the elastic telescopic rod, the limit block is inserted into the limit groove to limit the palm frame.

[0009] According to the above technical solution, the protective device also includes a long rod, a spring piece and an arc block. The long rod is fixedly installed on the inner wall of the vertical rod, the spring piece is fixedly installed on the side of the long rod close to the palm frame, and the arc block is fixedly installed on the side of the palm frame close to the long rod. When the palm frame moves up and down, the arc block is driven to move up and down. The arc block moves up and down and contacts with the spring piece and generates vibration to clean the lint on the palm frame.

[0010] According to the above technical solution, a limiting groove is provided on the inner wall of the vertical rod, and the side of the limiting block close to the palm frame is a No. 2 inclined surface. There are two limiting blocks, and the two limiting blocks are symmetrically distributed around the center of the palm frame. There are two palm frames, and the two palm frames are symmetrically distributed around the center of the vertical rod, which facilitates the resetting of the limiting block to release the limitation on the palm frame, thereby improving the applicability of the loom.

[0011] According to the above technical solution, the cleaning device includes a fiber block, a friction rod, a No. 2 L-shaped plate and a collecting trough, the fiber block is fixedly mounted on the inner wall of the vertical rod, the friction rod is slidably mounted on the surface of the fiber block, one end of the No. 2 L-shaped plate is fixedly mounted on the side of the palm frame away from the long rod, and the other end of the No. 2 L-shaped plate is fixedly mounted on the side of the friction rod away from the fiber block, and the collecting trough is fixedly mounted on the inner wall of the vertical rod, and the No. 2 L-shaped plate moves up and down to drive the friction rod to move up and down, and the friction rod moves up and down to rub the fiber block, so that the fiber block generates static electricity, which absorbs the fluff dropped by the vibration of the palm frame.

[0012] According to the above technical solution, the cleaning device also includes a square plate, a card plate, an L-shaped sliding rod and a pressure block. The square plate is fixedly installed on the top of the fiber block, the card plate is fixedly installed on the inner wall of the vertical rod, the L-shaped sliding rod is slidably installed on the side of the square plate close to the second L-shaped plate, and the pressure block is fixedly installed on the top of the L-shaped sliding rod. The second L-shaped plate contacts and squeezes the pressure block. The pressure block moves downward under the extrusion force. The downward movement of the pressure block drives the L-shaped sliding rod to move downward, thereby squeezing the fluff scraped up by the friction rod.

[0013] According to the above technical solution, a No. 1 spring is provided between the square plate and the L-shaped sliding rod, an L-shaped hole is opened on the surface of the card plate, two friction rods are provided, and the two friction rods are symmetrically distributed around the center of the fiber block, and two No. 2 L-shaped plates are provided, and the two No. 2 L-shaped plates are symmetrically distributed around the center of the fiber block, which facilitates the resetting of the L-shaped sliding rod and the downward sliding of the L-shaped sliding rod to squeeze the fluff.

[0014] The present invention provides a wide-width hand loom, which has the following beneficial effects: (1) In this invention, when the loom is working, the worker steps on the pedal. When the pedal moves downward, the oil tank is squeezed by the squeezing rod, so that oil is sprayed out from the oil outlet pipe to lubricate the rotating shaft, thereby reducing friction, ensuring smooth operation, extending the service life of the pedal, reducing noise, improving work efficiency, and reducing subsequent maintenance costs. At the same time, when the oil spray plate sprays too much oil, the excess oil will flow back to the inside of the oil tank through the return pipe to prevent excessive oil spraying from causing waste and increasing costs.

[0015] (2) This invention limits the upward and downward movement of the palm frame by means of a limiting rod and a limiting groove, thereby preventing the palm frame from moving too far upward and downward, which would cause the shed to open too wide, resulting in uneven weft distribution, uneven cloth surface, yarn skipping or weft breakage, and thus reducing the quality of the finished product. At the same time, the palm frame is vibrated by the contact between the spring piece and the arc block, thereby cleaning the lint on the palm frame and preventing the lint on the palm frame from being excessive, increasing friction, causing thread breakage, reducing work efficiency, and increasing costs.

[0016] (3) This invention generates static electricity in the fiber block by rubbing the friction rod against the fiber block, and collects the fluff that falls due to vibration. The static electricity has a strong adsorption effect on the fluff, making the working environment cleaner and reducing the impact of the fluff on equipment, products and workers' health. It helps to improve product quality and avoid defects caused by the fluff adhering to the fabric. It is also beneficial to the workers' respiratory health and reduces the occurrence of respiratory diseases. At the same time, the L-shaped sliding rod and the friction rod can squeeze the fluff on the surface of the limit block, causing the fluff to fall into the collection box, making it convenient for the staff to centrally handle the fluff later.

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figures 1-8 One embodiment of the present invention is as follows: a wide-width hand loom, comprising a loom body 1, a vertical rod 2 fixedly mounted on the inner wall of the loom body 1, a weft pressing plate 3 rotatably mounted on the inner wall of the loom body 1, a No. 1 L-shaped plate 4 fixedly mounted on the inner wall of the loom body 1, wherein the lubricating device comprises a rotating shaft 51, a pedal 52, an oil tank 53, an extrusion rod 54, a guide plate 55, a sealing plate 56, a return pipe 57, an oil outlet pipe 58 and an oil spray plate 59, the rotating shaft 51 rotates through the No. 1 L-shaped plate 4, the pedal 52 is fixedly mounted on the circumferential surface of the rotating shaft 51, the oil tank 53 is fixedly mounted on the side of the No. 1 L-shaped plate 4 close to the vertical rod 2, the extrusion rod 54 slides through the inner and outer walls of the oil tank 53, the extrusion rod 54 is connected to the bottom of the pedal 52, the guide plate 55 is slidably installed on the inner wall of the oil tank 53, the sealing plate 56 is slidably installed on the inner wall of the oil tank 53, and a groove is provided on the top of the No. 1 L-shaped plate 4. The groove is connected to the oil tank 53 through a return pipe 57. The injection plate 59 is fixedly installed inside the groove. The injection plate 59 is connected to the oil tank 53 through an oil outlet pipe 58. By squeezing the guide plate 55, oil is sprayed out from the injection plate 59 to lubricate the rotating shaft 51 by spraying oil, reducing friction, ensuring smooth operation, extending the service life of the pedal 52, reducing noise, improving work efficiency, and reducing later maintenance costs.

[0021] The upper surface of the guide plate 55 is provided with a No. 1 slope, an air valve is provided on the top of the oil tank 53, the bottom of the squeezing rod 54 is fixedly connected to the guide plate 55, and two pedals 52 are provided. The two pedals 52 are symmetrically distributed around the center of the textile machine body 1, which facilitates the recovered oil to flow into the bottom of the oil tank 53 and facilitates the squeezing rod 54 to squeeze the guide plate 55.

[0022] When this embodiment is working: when the loom is working, the staff steps on the pedal 52 and squeezes the pedal 52 so that the pedal 52 can rotate up and down. When the pedal 52 rotates downward, it drives the squeezing rod 54 to move downward. The squeezing rod 54 moves downward and drives the guide plate 55 to move downward. The guide plate 55 moves downward and contacts the sealing plate 56 to seal the oil tank 53. At the same time, the guide plate 55 continues to move downward, driving the sealing plate 56 to move downward, so that the oil enters the oil spray plate 59 from the oil outlet pipe 58 and is then sprayed from the oil spray plate 59 to spray oil and lubricate the rotating shaft 51, reducing friction, ensuring smooth operation, extending the service life of the pedal 52, reducing noise and improving work efficiency, and reducing later maintenance costs. At the same time, when the oil spray plate 59 sprays too much oil, the excess oil will be returned to the oil tank 53 through the return pipe 57 to prevent excessive oil spraying from causing waste and increasing costs.

[0023] See also Figures 1-8 The elastic telescopic rod 64 and the limit block 65 are used to limit the palm frame 62, so as to prevent the palm frame 62 from moving up and down too far, resulting in the shed opening being too large, so that the weft yarn cannot be evenly distributed, resulting in uneven cloth surface, yarn skipping or weft breakage, thereby reducing the quality of the finished product.

[0024] The protective device also includes an elongated rod 66, a spring piece 67 and an arc block 68. The elongated rod 66 is fixedly mounted on the inner wall of the vertical rod 2, the spring piece 67 is fixedly mounted on the side of the elongated rod 66 close to the palm frame 62, and the arc block 68 is fixedly mounted on the side of the palm frame 62 close to the elongated rod 66. Vibration is generated by the contact between the spring piece 67 and the arc block 68 to clean the lint on the palm frame 62, thereby preventing excessive lint on the palm frame 62, increasing friction, causing line breakage, and reducing work efficiency.

[0025] A limiting groove is provided on the inner wall of the vertical rod 2, and the side of the limiting block 65 close to the palm frame 62 is a No. 2 inclined surface. Two limiting blocks 65 are provided, and the two limiting blocks 65 are symmetrically distributed around the center of the palm frame 62. There are two palm frames 62, and the two palm frames 62 are symmetrically distributed around the center of the vertical rod 2, which makes it convenient for the limiting block 65 to reset and release the limit on the palm frame 62, thereby improving the applicability of the loom.

[0026] The cleaning device includes a fiber block 71, a friction rod 72, a second L-shaped plate 73 and a collecting trough 78. The fiber block 71 is fixedly mounted on the inner wall of the vertical rod 2, and the friction rod 72 is slidably mounted on the surface of the fiber block 71. One end of the second L-shaped plate 73 is fixedly mounted on the side of the palm frame 62 away from the long rod 66, and the other end of the second L-shaped plate 73 is fixedly mounted on the side of the friction rod 72 away from the fiber block 71. The collecting trough 78 is fixedly mounted on the inner wall of the vertical rod 2. The friction rod 72 moves up and down to rub the fiber block 71 to generate static electricity, which absorbs the vibrated hair, reduces the impact of the hair on equipment, products and workers' health, and helps to improve product quality.

[0027] The cleaning device also includes a square plate 74, a card plate 75, an L-shaped sliding rod 76 and a pressure block 77. The square plate 74 is fixedly mounted on the top of the fiber block 71, the card plate 75 is fixedly mounted on the inner wall of the vertical rod 2, the L-shaped sliding rod 76 is slidably mounted on the side of the square plate 74 close to the second L-shaped plate 73, and the pressure block 77 is fixedly mounted on the top of the L-shaped sliding rod 76. By squeezing the pressure block 77 and the L-shaped sliding rod 76, the fluff on the top of the fiber block 71 is squeezed downward, so that the fluff on the top of the fiber block 71 falls into the collection tank 78, which is convenient for the staff to centrally handle it later.

[0028] A No. 1 spring is provided between the square plate 74 and the L-shaped sliding rod 76, an L-shaped hole is provided on the surface of the clamping plate 75, two friction rods 72 are provided, and the two friction rods 72 are symmetrically distributed around the center of the fiber block 71, and two No. 2 L-shaped plates 73 are provided, and the two No. 2 L-shaped plates 73 are symmetrically distributed around the center of the fiber block 71, so as to facilitate the resetting of the L-shaped sliding rod 76 and the downward sliding of the L-shaped sliding rod 76 to squeeze the fluff.

[0029] When this embodiment is working: when the pedal 52 rotates up and down, it drives the connecting rope 61 to move, and the connecting rope 61 moves, which drives the palm frame 62 to move. When one palm frame 62 moves downward, the other palm frame 62 moves upward to form a shed, which is convenient for the shuttle to shuttle back and forth. At the same time, when the palm frame 62 moves up and down, it drives the limit block 65 to move up and down. When the limit block 65 moves up and down a certain distance, it contacts the limit groove and, under the action of the elastic telescopic rod 64, the limit block 65 is inserted into the limit groove to limit the palm frame 62, preventing the palm frame 62 from moving up and down too much, which causes the shed to open too wide. , so that the weft yarn cannot be evenly distributed, the cloth surface is uneven, the yarn is skipped or the weft is broken, which leads to a decrease in the quality of the finished product. At the same time, when the palm frame 62 moves in the opposite direction, the limit block 65 is reset by squeezing the second inclined surface. The reset of the limit block 65 releases the limit on the palm frame 62, thereby improving the practicality of the loom. At the same time, when the palm frame 62 moves up and down, it drives the arc block 68 to move up and down. The arc block 68 moves up and down and contacts the spring piece 67 and generates vibration, which cleans the lint on the palm frame 62 to prevent the lint on the palm frame 62 from being too much, increasing friction, causing line breakage, reducing work efficiency, and increasing costs.

[0030] When the second L-shaped plate 73 moves downward, the second L-shaped plate 73 moves upward and downward, and the second L-shaped plate 73 moves upward and downward, driving the friction rod 72 to move upward and downward. The friction rod 72 moves up and down to rub the fiber block 71, causing the fiber block 71 to generate static electricity, which absorbs the fluff dropped by the vibration of the palm frame 62, making the working environment cleaner and reducing the impact of the fluff on equipment, products and workers' health. When the second L-shaped plate 73 moves downward a certain distance, the second L-shaped plate 73 contacts and squeezes the pressure block 77. The pressure block 77 moves downward under the squeezing force. The downward movement of the pressure block 77 drives the L-shaped sliding rod 76 to move downward, squeezing the fluff scraped up by the friction rod 72, causing the fluff to fall into the collection tank 78. At the same time, the upward and downward movement of the friction rod 72 can also scrape the surface of the fiber block 71, preventing the surface of the fiber block 71 from absorbing too much fluff, which causes the static effect to deteriorate, thereby affecting the adsorption effect. At the same time, the scraped fluff falls into the collection tank 78, which is convenient for the staff to centrally process later and improve work efficiency.

[0031] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
