Description

Technical Field

[0001] This invention relates to the field of pressing device technology, and more particularly to a pressing device and a loom. Background Technology

[0002] The gripping force of the take-up mechanism on the fabric affects whether the weft position can be stably controlled. Only by ensuring that the weft position remains unchanged can normal fabric weaving production be guaranteed. Factors such as the magnitude of the clamping force formed by the take-up pressure roller and the take-up roller, as well as the type of rubber wrapped around each roller, all affect the gripping force of the take-up mechanism on the fabric. However, the biggest influencing factor is the clamping force between the take-up pressure roller and the take-up roller. This clamping force must be just right for the fabric. If the clamping force is too large, it will cause defects on the fabric surface and damage to the rubber wrapped around the roller. If the clamping force is too small, the fabric gripping force will be insufficient, affecting the weft position.

[0003] Most existing take-up pressure roller clamping devices install the pressure roller in a fixed position, forming a fixed clamping position with the take-up roller. This makes it impossible to conveniently adjust the clamping position according to the weaving requirements of different fabrics. The adjustment process of the clamping position is relatively complicated, wasting a lot of time and manpower, and reducing the adjustment efficiency of the clamping device.

[0004] Therefore, how to improve the adjustment efficiency of the clamping device is a technical problem that needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the object of the present invention is to provide a clamping device to improve the adjustment efficiency of the clamping device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0016] The first circumferential groove and the second circumferential groove are arranged along the circumference of the clamping adjustment block. The axes of the first mounting hole and the second mounting hole are arranged parallel to the axis of the clamping adjustment block. The first circumferential groove and the first mounting hole are connected, and the second circumferential groove and the second mounting hole are connected. The first connecting rod passes through the first circumferential groove and is connected to the first hinge shaft. The second connecting rod passes through the second circumferential groove and is connected to the second hinge shaft.

[0017] Optionally, in the above-mentioned clamping device, the clamping adjustment block is further provided with a third mounting hole and a fourth mounting hole;

[0018] The support base is fixedly provided with a fixed shaft, the third mounting hole is rotatably engaged with the fixed shaft, one end of the stop shaft is slidably disposed in the groove of the handle, and the other end is installed in the fourth mounting hole.

[0019] Optionally, in the above-mentioned pressing device, the first connecting rod is hinged to the first pressure roller through a third hinge shaft, and the second connecting rod is hinged to the second pressure roller through a fourth hinge shaft. The center line connecting the first hinge shaft and the third hinge shaft is the first connecting line, and the center line connecting the second hinge shaft and the fourth hinge shaft is the second connecting line.

[0020] Wherein, when the first pressure roller and the second pressure roller are pressing the take-up roller together, the first connecting line is located on the side of the fixed shaft close to the take-up roller, and the second connecting line is located on the side of the fixed shaft close to the take-up roller.

[0021] Optionally, in the above-described pressing device, the first pressure roller includes:

[0022] The first pressure roller seat has its first end rotatably mounted on the support seat;

[0023] The first pressure roller cover has a first end rotatably mounted on the support base, and the rotation axis of the first pressure roller cover coincides with the rotation axis of the first pressure roller base.

[0024] Fasteners securely connect the second end of the first pressure roller seat and the second end of the first pressure roller cover, forming a receiving space between the first pressure roller seat and the first pressure roller.

[0025] The first pressure roller body is disposed in the accommodating space.

[0026] Optionally, in the above-described clamping device, the fasteners include bolts, nuts, and elastic elements;

[0027] The bolt's thread passes through the second end of the first pressure roller seat and the second end of the first pressure roller cover before connecting to the nut. The elastic element is installed between the nut and the first pressure roller cover or between the head of the bolt and the first pressure roller seat.

[0028] Optionally, in the above-mentioned pressing device, a support shaft is fixedly provided on the support base, and the first end of the first pressure roller seat and the first end of the first pressure roller cover are both hinged to the support base through the support shaft.

[0033] A loom includes a take-up roller and a pressing device as described above.

[0034] When using the clamping device provided by this invention, since both the handle and the clamping adjustment block are rotatably mounted on the support base, and the stop shaft on the clamping adjustment block is slidably mounted in the groove on the handle, when the handle is rotated downwards, the groove on the handle pushes the stop shaft to rotate in the first direction, which in turn causes the clamping adjustment block to rotate in the first direction. Since the two ends of the linkage assembly are rotatably connected to the clamping adjustment block and the pressure roller assembly respectively, when the clamping adjustment block rotates in the first direction, it will drive the pressure roller assembly to rotate in the first direction through the linkage assembly. In this embodiment of the invention, the pressure roller assembly rotates downwards and clamps the winding mechanism. When the handle is turned upwards, the groove on the handle pushes the stop shaft to rotate in the second direction, which means that the pressure adjustment block rotates in the second direction. The second direction is opposite to the first direction. Based on the fact that the two ends of the linkage assembly are respectively rotatably connected to the pressure adjustment block and the pressure roller assembly, when the pressure adjustment block rotates in the second direction, it will drive the pressure roller assembly to rotate in the second direction through the linkage assembly. In the embodiment of the present invention, the pressure roller assembly rotates downwards and presses the take-up roller, so that a gap is created between the pressure roller assembly and the take-up roller, which allows for quick and easy operation when feeding or adjusting the fabric surface.

[0035] Therefore, the pressing device provided by the present invention can quickly switch between pressing and lifting actions of the pressure roller assembly, reducing the complexity of operation for the operator, saving a lot of time and manpower, and improving the adjustment efficiency of the pressing device.

Detailed Implementation

[0045] In view of this, the core of the present invention is to provide a clamping device to improve the adjustment efficiency of the clamping device.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] like Figures 1 to 7 As shown in the figure, an embodiment of the present invention discloses a pressing device, including a support base 100, a pressure roller assembly 200, a handle 300, a pressing adjustment block 400, and a connecting rod assembly 500.

[0048] The pressure roller assembly 200 is rotatably mounted on the support base 100; the handle 300 is rotatably mounted on the support base 100, and the handle 300 is provided with a sliding groove 301; the pressing adjustment block 400 is rotatably mounted on the support base 100, and the pressing adjustment block 400 is provided with a stop shaft 405, which is slidably mounted in the sliding groove 301; the two ends of the connecting rod assembly 500 are rotatably connected to the pressing adjustment block 400 and the pressure roller assembly 200, respectively.

[0049] When using the clamping device provided by this invention, since both the handle 300 and the clamping adjustment block 400 are rotatably mounted on the support base 100, and the stop shaft 405 on the clamping adjustment block 400 is slidably mounted in the groove 301 on the handle 300, when the handle 300 is rotated downwards, the groove 301 on the handle 300 pushes the stop shaft 405 to rotate in the first direction, that is, the clamping adjustment block 400 rotates in the first direction. Since the two ends of the connecting rod assembly 500 are respectively rotatably connected to the clamping adjustment block 400 and the pressure roller assembly 200, when the clamping adjustment block 400 rotates in the first direction, it will drive the pressure roller assembly 200 to rotate in the first direction through the connecting rod assembly 500. In this embodiment of the invention, the pressure roller assembly 200 rotates downwards. The take-up roller 600 is pressed down. When the handle 300 is turned upward, the slide groove 301 on the handle 300 pushes the stop shaft 405 to rotate in the second direction, that is, the pressing adjustment block 400 rotates in the second direction. The second direction is opposite to the first direction. Since the two ends of the connecting rod assembly 500 are respectively rotatably connected to the pressing adjustment block 400 and the pressure roller assembly 200, when the pressing adjustment block 400 rotates in the second direction, it will drive the pressure roller assembly 200 to rotate in the second direction through the connecting rod assembly 500. In this embodiment of the invention, the pressure roller assembly 200 rotates downward and presses down on the take-up roller 600, so that a gap is created between the pressure roller assembly 200 and the take-up roller 600, so that the operation can be carried out quickly and easily when feeding or adjusting the fabric.

[0050] Therefore, the pressing device provided by the present invention can quickly switch between the pressing action and the lifting action of the pressure roller assembly 200, reduce the complexity of the operator's operation, save a lot of time and manpower, and improve the adjustment efficiency of the pressing device.

[0051] It should be noted that the above-mentioned pressure roller assembly 200 may include one pressure roller, or two or three pressure rollers. The present invention does not limit the specific number of pressure rollers in the pressure roller assembly 200. As long as the number can meet the usage requirements, it is within the protection scope of the present invention.

[0052] Optionally, the pressure roller assembly 200 provided in this embodiment of the invention includes a first pressure roller 201 and a second pressure roller 202. Both the first pressure roller 201 and the second pressure roller 202 are rotatably mounted on the support base 100. The center line connecting the first pressure roller 201 and the take-up roller 600 is a first connecting line T1, and the center line connecting the second pressure roller 202 and the take-up roller 600 is a second connecting line T2. The angle between the first connecting line T1 and the second connecting line T2 is greater than 0° and less than 180°, that is, the first pressure roller 201 and the second pressure roller 202 are located on the same side of the take-up roller 600. The connecting rod assembly 500 includes a first connecting rod. 501 and 502 are connected. The two ends of the first connecting rod 501 are rotatably connected to the pressing adjustment block 400 and the first pressure roller 201, respectively. The two ends of the second connecting rod 502 are rotatably connected to the pressing adjustment block 400 and the second pressure roller 202, respectively. This allows the sliding groove 301 on the handle 300 to push the stop shaft 405 to rotate in the first direction when the handle 300 is turned downwards. This causes the pressing adjustment block 400 to rotate in the first direction. Since the pressing adjustment block 400 is rotatably connected to the first pressure roller 201 via the first connecting rod 501 and to the second pressure roller 202 via the second connecting rod 502, the pressing adjustment block 401... The first pressure roller 201 is driven to rotate in a first direction via the first connecting rod 501, and the second pressure roller 202 is driven to rotate in the first direction via the second connecting rod 502. In this embodiment of the invention, both the first pressure roller 201 and the second pressure roller 202 rotate downwards to press the take-up roller 600. When the handle 300 is turned upwards, the sliding groove 301 on the handle 300 pushes the stop shaft 405 to rotate in a second direction, that is, the pressing adjustment block 400 rotates in the second direction. The second direction is opposite to the first direction. The pressing adjustment block 400 is rotatably connected to the first pressure roller 201 via the first connecting rod 501. The second pressure roller 202 is rotatably connected via the second connecting rod 502. Therefore, the pressing adjustment block 400 drives the first pressure roller 201 to rotate in the second direction via the first connecting rod 501, and drives the second pressure roller 202 to rotate in the second direction via the second connecting rod 502. In this embodiment of the invention, both the first pressure roller 201 and the second pressure roller 202 rotate upward and lift up, so that both the first pressure roller 201 and the second pressure roller 202 have gaps with the take-up roller 600. This allows for quick and easy operation when feeding or adjusting the fabric surface. In addition, the double pressure roller pressing can also increase the winding tension of the fabric and improve the weaving quality of the fabric.

[0053] Furthermore, the aforementioned clamping adjustment block 400 has a cylindrical structure, and is provided with a first circumferential groove 401, a second circumferential groove 402, a first mounting hole 403, and a second mounting hole 404. A first hinge shaft 503 is rotatably disposed in the first mounting hole 403, and a second hinge shaft 504 is rotatably disposed in the second mounting hole 404. The first circumferential groove 401 and the second circumferential groove 402 are arranged circumferentially along the clamping adjustment block 400. The axes of the first mounting hole 403 and the second mounting hole 404 are parallel to the axis of the clamping adjustment block 400. The first circumferential groove 401 and the first mounting hole 403 are connected, and the second circumferential groove 402 and the second mounting hole 404 are connected. A first connecting rod 501 passes through the first circumferential groove 401 and connects to the first hinge shaft 503. A second connecting rod 502 passes through the second circumferential groove 402 and connects to the second hinge shaft 504, so as to pass through the first circumferential groove... The first connecting rod 501 is limited by the second circumferential groove 402 to prevent it from wobbling during motion transmission. The second connecting rod 502 is also limited by the second circumferential groove 402 to prevent it from wobbling during motion transmission, thus improving the stability of the clamping device's adjustment process. Furthermore, since the first connecting rod 501 is rotatably connected to the clamping adjustment block 400 via the first hinge shaft 503, the rotation of the clamping adjustment block 400 will drive the first pressure roller 201 to rotate via the first connecting rod 501, switching the clamping and lifting actions of the first pressure roller 201 on the take-up roller 600. Similarly, since the second connecting rod 502 is rotatably connected to the clamping adjustment block 400 via the second hinge shaft 504, the rotation of the clamping adjustment block 400 will drive the second pressure roller 202 to rotate via the second connecting rod 502, switching the clamping and lifting actions of the second pressure roller 202 on the take-up roller 600.

[0054] like Figure 6 and Figure 7 As shown, the clamping adjustment block 400 is also provided with a third mounting hole 406 and a fourth mounting hole 407; wherein, a fixed shaft 102 is fixedly provided on the support base 100, and the third mounting hole 406 is rotatably engaged with the fixed shaft 102 so that when the clamping adjustment block 400 rotates to the point where the first connecting rod 501 or the second connecting rod 502 contacts the fixed shaft 102, the fixed shaft 102 acts to block the rotation of the clamping adjustment block 400, so that the first pressure roller 201 and the second pressure roller 202 are in a clamping state; one end of the stop shaft 405 is slidably disposed in the slide groove 301 of the handle 300, and the other end is installed in the fourth mounting hole 407 so that when the handle 300 is rotated, the slide groove 301 pushes the stop shaft 405 to rotate, and based on the rotation of the stop shaft 405, the clamping adjustment block 400 also rotates accordingly, thereby driving the first pressure roller 201 and the second pressure roller 202 to perform the switching between the clamping action and the lifting action on the take-up roller 600.

[0055] like Figure 4 and Figure 5 As shown, Figure 4 The solid line portion is a schematic diagram of the structure when the first pressure roller 201 presses the take-up roller 600 tightly, and the dashed line portion is a schematic diagram of the structure when the second pressure roller 202 presses the take-up roller 600 tightly. Figure 5 The dashed section represents a structural diagram when the first pressure roller 201 presses against the take-up roller 600, and the solid section represents a structural diagram when the second pressure roller 202 presses against the take-up roller 600. Specifically, the first connecting rod 501 is hinged to the first pressure roller 201 via a third hinge shaft 505, and the second connecting rod 502 is hinged to the second pressure roller 202 via a fourth hinge shaft 506. The center line connecting the first hinge shaft 503 and the third hinge shaft 505 is the first connecting line T1, and the center line connecting the second hinge shaft 504 and the fourth hinge shaft 506 is the second connecting line T2. The solid section represents a structural diagram when the first pressure roller 201 and the second pressure roller 600 press against each other. When the roller 202 is pressing the take-up roller 600, the first connecting line T1 is located on the side of the center of the fixed shaft 102 close to the take-up roller 600. That is, during the pressing adjustment process, the first connecting line T1 should rotate from the outside of the center of the fixed shaft 102 to the inside of the center of the fixed shaft 102. In addition, the second connecting line T2 is also located on the side of the center of the fixed shaft 102 close to the take-up roller 600. That is, during the pressing adjustment process, the second connecting line T2 should rotate from the outside of the center of the fixed shaft 102 to the inside of the center of the fixed shaft 102, so that the pressing device can maintain a stable pressing state.

[0056] The terms “inner side of the center of fixed shaft 102” and “outer side of the center of fixed shaft 102” are relative to the center of fixed shaft 102. “Inner side of the center of fixed shaft 102” refers to the side of the center of fixed shaft 102 that is closer to the take-up roller 600, and “outer side of the center of fixed shaft 102” refers to the side of the center of fixed shaft 102 that is away from the take-up roller 600.

[0057] like Figures 1 to 5As shown, the first pressure roller 201 includes a first pressure roller seat 2011, a first pressure roller cover 2012, a fastener 2013, and a first pressure roller body 2015; wherein, the first end of the first pressure roller seat 2011 is rotatably mounted on the support base 100, and the first end of the first pressure roller cover 2012 is rotatably mounted on the support base 100, and the rotation axis of the first pressure roller cover 2012 coincides with the rotation axis of the first pressure roller seat 2011, and the second end of the first pressure roller seat 2011 and the second end of the first pressure roller cover 2012 are fastened together, and an accommodating space is formed between the first pressure roller seat 2011 and the first pressure roller 201. The main body 2015 is disposed in the receiving space so that the opening and closing between the first pressure roller cover 2012 and the first pressure roller seat 2011 can be realized by the rotation of the second end of the first pressure roller cover 2012 relative to the first pressure roller seat 2011. This facilitates placing the first pressure roller body 2015 in the receiving space and then locking the first pressure roller body 2015 in the receiving space by fasteners 2013. The rotation of the first pressure roller seat 2011 on the support 100 allows the first pressure roller 201 as a whole to rotate relative to the support 100, thereby realizing the switching between the pressing action and the lifting action of the first pressure roller 201.

[0058] In addition, the fastener 2013 mentioned above can be a bolt assembly or a snap-fit ​​component, etc. Any type of fastener 2013 that can meet the usage requirements is within the protection scope of this invention; optionally, the fastener 2013 provided in the embodiments of this invention adopts a bolt assembly, which has a simple structure and is easy to assemble.

[0059] Specifically, the fastener 2013 includes a bolt, a nut, and an elastic element 2014; wherein, the bolt's shank passes through the second end of the first pressure roller seat 2011 and the second end of the first pressure roller cover 2012 and is connected to the nut, and the elastic element 2014 is installed between the nut and the first pressure roller cover 2012 or between the head of the bolt and the first pressure roller seat 2011, so that when the handle 300 is turned to press the first pressure roller body 2015 against the take-up roller 600, the elastic element 2014 ensures that the pressing force between the first pressure roller body 2015 and the take-up roller 600 is appropriate, and provides a buffering and protective effect on the fabric surface and the roller body winding rubber.

[0060] It should be understood that the above-mentioned elastic element 2014 can be a spring or a rubber block, etc. Any elastic element 2014 that can meet the usage requirements is within the protection scope of this invention; Optionally, the elastic element 2014 provided in the embodiment of this invention is a spring, so that it can be directly sleeved on the bolt for easy assembly.

[0061] The support base 100 provided by the present invention is fixedly provided with a support shaft 101. The first end of the first pressure roller seat 2011 and the first end of the first pressure roller cover 2012 are both hinged to the support base 100 through the support shaft 101. On the one hand, the support shaft 101 supports the first pressure roller 201, and on the other hand, the first pressure roller 201 as a whole can rotate around the support shaft 101 to realize the switching between pressing action and lifting action.

[0062] The structure of the second pressure roller 202 and the first pressure roller 201 may be the same or different. As long as the structure can meet the usage requirements, it is within the protection scope of this invention. Optionally, the second pressure roller 202 provided in the embodiment of this invention has the same structure as the first pressure roller 201 in order to improve the generalization rate of component structure and reduce costs.

[0063] Furthermore, the clamping device also includes an automatic clamping control module, which includes a receiving unit, a calculation unit, and an execution unit. The receiving unit receives a preset clamping force value, the calculation unit calculates the rotation direction and angle of the handle 300 based on the preset clamping force value, and the execution unit drives the handle 300 to rotate based on the rotation direction and angle of the handle 300. This allows the clamping device to automatically adjust the clamping force through the automatic clamping control module, thereby improving the automation level of the clamping device, further reducing manpower and time waste, and improving the adjustment efficiency of the clamping device.

[0064] It should be understood that the aforementioned receiving unit can directly receive the preset clamping force value input manually, or it can detect the fabric type signal through the detection element and convert the fabric type information into an electrical signal and transmit it to the receiving unit. The receiving unit generates the preset clamping force value based on the fabric type information, further improving the automation level of the clamping device.

[0065] In addition, the present invention also discloses a loom, including a take-up roller 600 and a pressing device as described in any of the above claims. Therefore, the loom includes all the technical effects of the above-mentioned pressing device, which will not be described in detail here.

[0066] The terms "first" and "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units may include steps or units not listed, but rather steps or units not listed.
