Description

Technical Field

[0001] The utility model relates to the field of clothing processing equipment, in particular to a device for elastic conveying with a conveyor belt. Background Art

[0002] The working principle of seamless heat press in the field of clothing is to use high temperature and pressure to melt hot melt adhesive film or hot melt adhesive, and then press two or more layers of superimposed fabrics together to form a permanent bond. Figure 1 As shown, the fabric is typically placed on the conveyor of a seamless heat press. Cylinder 3 then drives pressure device 1 downward onto the conveyor belt of conveyor device 2, pressing the fabric layers against the heated hot melt adhesive film or adhesive to achieve multi-layered bonding. The conveyor belt then transports the fabric forward, allowing the hot-pressed, bonded fabric to be discharged. This bonding method ensures smooth, soft seams on garments without damaging fabric fibers, while also providing excellent sealing and waterproof properties.

[0003] However, the gap between the pressure device and the conveyor belt is fixed after pressing down. When the total thickness of the stacked layers of fabric is uneven, it may cause part of the stacked layers of fabric to be too thin and unable to be pressed tightly, affecting the bonding quality, or part of the stacked layers of fabric to be too thick and get stuck between the pressure device and the conveyor belt, causing the equipment to not operate normally. Utility Model Content

[0004] In view of the deficiencies raised in the above background technology, the utility model provides a device for elastic conveying of a conveyor belt.

[0005] The utility model adopts the following technical solutions:

[0006] A device for elastic conveying of a conveyor belt, characterized in that the device comprises:

[0007] Side plates are provided on both sides of the conveyor belt, and a row of penetrating adjustment holes are provided on the side plates along the conveying direction of the conveyor belt. The adjustment holes of the two side plates correspond to each other one by one, and the adjustment holes are vertical strip holes, and a placement hole is provided on the bottom surface of each adjustment hole;

[0008] A support roller, wherein a support shaft is installed in the center of the support roller, and both ends of the support shaft are respectively inserted into the two corresponding adjustment holes, so that the support roller is located between the two side plates, and the conveyor belt passes through each of the support rollers;

[0009] A spring is embedded in each of the placement holes, and the elastic force of the spring stretching lifts the support shaft to the top surface of the adjustment hole.

[0010] In one possible implementation, the device also includes a guide pin, the spring is sleeved outside the guide pin, and the other end of the guide pin is embedded in the placement hole, one end of the guide pin is an expanded diameter portion with an enlarged diameter, and the upper end of the spring is against the expanded diameter portion, so that the elastic force of the stretched spring pushes up the expanded diameter portion.

[0011] In a possible implementation, the placement hole is a threaded hole that passes through the side plate. A spiral connecting bolt is adapted to fit in the threaded hole, and the bolt abuts against the lower end of the spring.

[0012] In a possible implementation, when the pressure device is located above the conveyor belt, the conveyor belt passes above each of the support rollers; when the pressure device is located below the conveyor belt, the conveyor belt passes below each of the support rollers.

[0013] In a possible implementation, the conveyor belt is a synchronous belt, and the support roller is a synchronous wheel.

[0014] From the above description of the structure of the present invention, it can be seen that compared with the prior art, the present invention has the following advantages: the present invention uses springs to push the two ends of the support roller to the ends of the adjustment hole, so as to push the conveyor belt out to remain outside the edge of the side plate to facilitate the conveying of fabrics, and when the pressure device is lowered to the conveyor belt, the distance between the conveyor belt and the pressure device can be elastically changed through the connection of the spring, forming an adaptive pressing for fabrics of different thicknesses, preventing the total thickness of the stacked multi-layer fabrics from being too thin to be pressed, and also preventing the total thickness of the stacked multi-layer fabrics from being too thick to be stuck in the pressure device and the conveyor belt. It can be seen that the structure of the present invention can ensure the bonding quality of multi-layer fabrics, and at the same time, it can also ensure the normal and orderly operation of the seamless hot press.

[0023] In addition, in this application, directional terms such as "upper" and "lower" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to changes in the orientation of the components in the drawings.

[0024] The utility model provides a device for elastic conveying of a conveyor belt, as shown in the attached Figure 2 and 4 As shown, the device includes side plates 22, support rollers 23 and springs 24. The side plates 22 are provided on both sides of the conveyor belt 21. The side plates 22 are provided with a row of through adjustment holes 221 along the conveying direction of the conveyor belt 21, and the adjustment holes 221 of the side plates 22 correspond to each other. Figure 5 The adjustment hole 221 is a vertical strip hole, and the side plate 22 is provided with a placement hole 222 on the end surface of one end of each adjustment hole 221 in the length direction.

[0025] Continue to refer to the attached Figure 5A support shaft 231 is installed through the center of the support roller 23. Preferably, bearings 232 are embedded and fixed in the end surfaces of both ends of the support roller 23. The support shaft 231 passes through the two bearings 232, so that the two ends of the support shaft 231 extend outside the two ends of the support roller 23. A retaining spring (not shown in the drawings) is installed on the end surface of the support shaft 231 facing the outer end of the support roller 23 to prevent relative axial movement between the support roller 23 and the support shaft 231. The two ends of the support shaft 231 are also inserted into two corresponding adjustment holes 221, so that the support roller 23 is located between the two side plates 22, and the conveyor belt 21 passes through each support roller 23. In addition, when the pressure device 1 is located above the conveyor belt 21, the conveyor belt 21 passes above each support roller 23. When the pressure device 1 is located below the conveyor belt 21, the conveyor belt 21 passes below each support roller 23. These two arrangements allow the pressure device 1 to simultaneously compress the spring 24 when applying pressure to the conveyor belt 21. This embodiment is described using the example of the pressure device 1 being located above the conveyor belt 21. Preferably, the conveyor belt 21 is a synchronous belt, and the support rollers 23 are synchronous pulleys. When the conveyor belt 21 passes over the support rollers 23, the synchronous pulleys engaged therewith are driven to rotate, thereby improving the stability of the conveyor belt 21 and the support rollers 23 after the conveyor belt 21 presses down on the support rollers.

[0026] As attached Figure 3 As shown, each placement hole 222 is embedded with a spring 24. The spring 24 can be embedded in a threaded hole 222 that extends through the side plate 22. A screw-type bolt 26 can be inserted into the placement hole 222. The bolt can be a headless bolt. After the spring 24 is positioned through the placement hole 222 with one end facing away from the adjustment hole 221 (through the bottom surface of the side plate 22), the bolt 26 is screwed into the placement hole 222, resting against the lower end of the spring 24. Preferably, two bolts 26 can be screwed into the placement hole 222 to enhance the securement of the bolt 26 within the placement hole 222. The above structure uses the elastic force of the spring 24 to lift the support shaft 231 to the top surface of the adjustment hole 221, thereby lifting the surface of the conveyor belt 21 by pushing the support roller 23 upward. By applying pressure to the surface of the conveyor belt 21, the conveyor belt 21 can be pressed down and the spring 24 can be compressed. It can be seen that the utility model makes the height of the conveyor belt 21 relative to the side plate 22 elastically variable, thereby making the gap between the conveyor belt 21 and the pressure device 1 elastically variable.

[0027] As the conveyor belt 21 conveys the fabric and the pressure device 1 presses the fabric downward, the elastic force of the stretched spring 24 pushes the support roller 23 upward, thereby pushing the fabric under the pressure device 1, so that the fabric can be subjected to sufficient pressure for hot pressing. At the same time, when the fabric is pressed by the pressure device 1 against the conveyor belt 21, the surface of the conveyor belt 21 can also compress the spring 24 when subjected to downward pressure, forming a conveyor belt suitable for fabrics of different thicknesses, avoiding the inability to convey excessively thick fabrics or fabrics that are too thin to generate the required pressure for hot pressing.

[0028] Continue to refer to the attached Figure 3 and 5 The device also includes a guide pin 25, which is placed in each placement hole 222. One end of the guide pin 25 has an enlarged diameter portion 251. After the spring 24 is sleeved over the guide pin 25, the spring 24 and guide pin 25 are then inserted into the placement hole 222, so that one end of the enlarged diameter portion 251 of the guide pin 25 is exposed within the adjustment hole 221. The other end of the guide pin 25 is inserted into the placement hole 222 and abuts against the screwed-in bolt 26. At the same time, the upper end of the spring 24 abuts against the enlarged diameter portion 251, allowing the spring 24 to lift the enlarged diameter portion 251 through the elastic force of tension, and then lift the connecting pin through the enlarged diameter portion 251. In this structure, the guide pin 25 can limit the spring 24, allowing the spring 24 to only be stretched or compressed vertically, preventing the spring 24 from skewing.

[0029] Furthermore, the side plates 22 are provided with a retaining portion 223 on the edge of the adjustment hole 221 facing away from the conveyor belt 21. The retaining portion 223 retains the end of the support shaft 231 within the adjustment hole 221, thereby confining the support shaft 231 between the side plates 22, allowing only rotation but not axial movement of the support roller 23. Alternatively, recessed retaining grooves (not shown) can be provided near the ends of the support shaft 231, with the upper end of the expanded diameter portion 251 of the guide pin 25 embedded in the retaining grooves. This also confines the ends of the support shaft 231 within the adjustment hole 221, allowing only rotation but not axial movement of the support roller 23.

[0030] In addition, the side panels 22 may be as shown in the attached Figure 6 The "7"-shaped structure shown is such that after the side panels 22 are fixed on the workbench 4 of the seamless hot press, the position below the conveyor belt 21 is suspended in the air to facilitate the pressing of tubular garments. For example, the fabric is formed into a tubular shape and then put on the horizontal parts of the two side panels 22, and the parts to be bonded are superimposed on the conveyor belt 21, so that the fabrics on both sides of the seam position where the fabrics need to be bonded move with the conveyor belt 21 and are pushed forward during the hot pressing process. This hot pressing method can prevent the unpressed parts from being pressed into deformation and wrinkles.

[0031] To sum up, in the structure of the present invention, the spring 24 is used to push the two ends of the support roller 23 to the end of the adjustment hole 221, so as to push the conveyor belt 21 out to remain outside the edge of the side plate 22, so as to facilitate the conveying of fabrics, and when the pressure device 1 is pressed down to the conveyor belt 21, the distance between the conveyor belt 21 and the pressure device 1 can be elastically changed through the connection of the spring 24, forming an adaptive pressing for fabrics of different thicknesses, so that the structure of the present invention can ensure the bonding quality of multi-layer fabrics, and at the same time, it can also enable the seamless hot press to always operate normally and orderly.

[0032] The above is only a specific implementation method of the present invention, but the design concept of the present invention is not limited to this. Any non-substantial changes to the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
